Problems solved by technology

However, most of the above methods are carried out on the surface of the seepage opening, which has little effect on filling the seepage channel inside the dam body, and it is difficult to repair the leaks deep in the water level, resulting in low repair efficiency

Embodiment 1

[0037] This embodiment illustrates the technical solution of the device of the present invention.

[0038] like figure 1 As shown, the robot of the present invention includes a magnetization unit 1, a material unit 2, a lifting unit 3, a detection unit 4, a cleaning unit 5, a moving unit 6 and a control unit 7;

[0039] like figure 2 As shown, the magnetization unit 1 includes a casing 1-1, a waterproof layer 1-2, and an electromagnetic coil 1-3. Use acrylic board to make a 30cm*30cm*5cm uncovered cuboid to form the shell 1-1; the waterproof layer 1-2 uses a potting compound with a relative density greater than 1, and the electromagnetic coil 1-3 uses a flat electromagnetic coil with a diameter of 20cm. Coils; cast potting compound in casing 1-1 to seal solenoid coils 1-3.

[0040] The material unit 2 includes a material accommodating cavity 2-1, an edge guard 2-2, a phase change material 2-3, a heating sheet 2-4, and a connecting wire 2-5. The material accommodating cavi...

Embodiment 2

[0045] This embodiment specifically illustrates the technical solution of the method of the present invention.

[0046] like image 3 As shown in the figure, a small concrete face dam has an erosion hole at a depth of 2m, and a leakage channel 9 is formed. The method of the present invention is used to repair, including the following steps:

[0047] 1) Preparation stage. The underwater plugging robot was fabricated and assembled in the manner described in Example 1, and the equipment was debugged to ensure normal operation.

[0048] 2) Launch positioning. The underwater situation is monitored by the detection unit, the underwater robot is controlled to locate the leakage position, and the cleaning unit is activated to clean up the debris attached to the leakage inlet. The hole is inside the edge guard box. Monitor the reading of the water pressure sensing device. If the reading changes significantly after the material unit is lowered to make the berm contact with the dam ...

Abstract

The invention relates to a negative pressure suction force based dam leakage blocking robot and an application method thereof. The robot comprises a magnetic generation unit, a material unit, a lifting unit, a detection unit, a cleaning unit, a moving unit and a control unit. The robot can repair underwater leakage damage on the water face of a dam, and two layers of blocking effects are achievedon a leakage channel, wherein firstly, a blocking function is achieved on the leakage path after molten-state phase change materials sucked into the leakage channel due to leakage negative pressure are solidified, and secondly, the material unit is bound to the slope face of the dam through residual phase change materials, and a protection function is achieved on the damage area around a leakage inlet so as to reduce further damage of a dam body.

Description

technical field [0001] The invention relates to a robot and a use method, in particular to a dam leakage sealing robot based on negative pressure suction and a use method thereof, and belongs to the technical field of emergency protection for leakage danger of dam engineering. Background technique [0002] At present, the main methods of rushing and blocking the leakage danger of dams mainly include front sloping, covering with geosynthetics to intercept seepage, caulking and water-stopping, etc. These methods have been used in practical projects for many years and have achieved corresponding results. However, most of the above methods are rush protection on the surface of the seepage opening, which has little effect on filling the seepage channel inside the dam body, and it is difficult to carry out the repair of the leaks deeper from the water level, resulting in low repair efficiency. In recent years, the method of underwater self-priming of phase change materials to seal...
