WALKIE-TALKIE

In order to adapt to the development of industry demands that keep up with the times, Qianxing is committed to providing revolutionary products and underwater application solutions with the strongest performance and good experience for public institutions and enterprise customers. It has been widely applied in various areas such as police fire rescue, aquaculture, port hull inspection, environmental protection and municipal administration, water conservancy and water affairs, scientific research and exploration, etc

Traditional salvage

Traditional inspections mainly involve divers or leasing large ROV underwater robots for inspection. Manual inspections pose significant safety risks, and the rental cost of large ROVs is high. For long-term and high-frequency inspection tasks, the cost is too high, and the machines are relatively bulky, resulting in poor shooting results

Underwater robot rescue

The traditional underwater rescue mainly involves the diving of frogman, and there are problems such as high diving cost, low efficiency, and high safety hazards. The addition of underwater robot submersible shark P100 can replace frogman to perform some underwater search work, reducing the originally estimated 5-hour working time to less than 3 hours, and improving the overall search efficiency by nearly 50%

The submersible shark P100 has a time advantage in deployment preparation. From assembly to launch preparation, it can be completed within 3 minutes, while the frogman usually requires nearly 20 minutes of preparation time before launching. In emergency situations, the submersible shark P100 is a good emergency equipment

The submersible P100 is performing underwater search work

The submersible P100 completed the search and rescue work on the Dnieper River

The Dnieper River passes through the capital of Ukraine, Kiev, and is the largest river in Ukraine and the fourth largest river in Europe

The main task of this case was carried out by the local police rescue team, deploying the submersible shark P100 and the frogman to search for the target object simultaneously. The addition of the submersible shark P100 increased the search and rescue efficiency by 50%

On site situation

The water flow in the search area is gentle, with a flow rate of less than 1m/s, visibility of about 0.5-1 meters, and water depth of 4-8 meters

Inspection plan

(1) Delineate a search area

(2) The submersible shark P100 deploys underwater on the shore and searches along the water below the bridge; Frogman takes a boat to the center of the river and simultaneously launches a carpet search (as shown in the picture)

(3) If the underwater robot searches for the target object, keep the machine at a fixed depth, and then let the frogman find and bind the target object along the machine cable

Process

1.3 minutes to complete the deployment of the submersible shark P100 (the robotic arm is mainly used to pick up underwater objects related to this task)

2. According to the plan, the diving shark P100 will search for water from the starting point on the shore

3. Carpet style search (The submersible P100 has a full vector layout of 8 thrusters, which can move 360° in all directions and can still operate stably and sensitively even equipped with a robotic arm)

Key point analysis

According to the operation interface, the depth of the search area for the submersible shark P100 is about 4.6m, with average visibility, less distribution of aquatic plants, and more sediment at the bottom (the submersible shark P100 is an anti jamming motor that can avoid faults caused by sand lifting after touching the bottom)

In the actual search process, the forward direction of the submersible P100 intersects vertically with the direction of river flow. The submersible P100 has good lateral anti flow ability, which largely maintains the aircraft body moving forward in the established channel without causing any deviation in the aircraft body position, in order to avoid affecting the search results and missing the target

Search Report

The submersible shark P100 successfully completed the search task, but no target object was found in the search area. This ruled out the possibility of the target object being in the area for the rescue team. At the same time, no target object was found in the Frogman search area. Based on the results of both, the rescue team will make a new plan and arrange for the search work in the next water area

Summary

1. Traditional inspections mainly involve divers or leasing large ROV underwater robots for inspection. Manual inspections pose significant safety hazards, and the rental cost of large ROVs is high. For long-term and high-frequency inspection tasks, the cost is too high, and the machines are relatively bulky, resulting in poor shooting results; The Qiansha P100 is a small, lightweight industrial underwater robot that is safe, economical, and easy to operate, improving work efficiency and safety

2. The submersible shark P100 is equipped with a 4K anti shake lens, providing clear image data for underwater inspections and assisting in more accurate analysis of terrain sonar surveying results

3. When observing a certain section of the rock mass, the user needs to keep the machine moving smoothly from left to right or in the± 90° Mobile observation, the submersible shark P100 is designed with an 8-push full vector layout, which can be used for fixed depth photography and observation in one posture

4. The Qiansha P100 is designed as a platform and supports multiple mounts. In this dam inspection, external LED lights and laser calipers were installed, significantly improving work efficiency

5. The Qiansha P100 can be equipped with an optional 200 watt hour battery and supports battery disassembly and replacement, expanding operation time
