Abstract
Description
Technical field:
[0001] The invention relates to the technical field of water conservancy engineering, and in particular to a gate foundation underwater crack desilting detector. Background technology:
[0002] In the daily operation of the water conservancy pump station, the gate is driven by the hoist to lift up and down along the two side foundations to realize the opening and closing function. The gate foundation includes the two side foundations and the bottom foundation, which are generally made of cement concrete. The two side foundations are used to guide the gate, and the bottom foundation is used to bear the weight. After long-term use, the bottom foundation is prone to cracks due to long-term stress, which cannot be found by the naked eye. Even if it is filmed by an underwater camera, these cracks are filled with silt at the bottom of the water for a long time. In addition, due to the fluidity of the water, it is difficult to determine whether there are cracks in the picture taken by the camera. At present, there is no good way to accurately detect whether there are cracks on the bottom foundation and the specific size of the cracks. Over time, the cracks continue to expand and deform. At the least, the foundations on both sides are deformed, causing the gate to rise and fall unsmoothly and easily malfunction. At the worst, the foundation becomes loose, forming a great safety hazard.
[0003] In summary, the problem of crack detection at the bottom foundation of the gate has become a technical problem that urgently needs to be solved in the industry. Summary of the invention:
[0004] In order to make up for the deficiencies of the prior art, the present invention provides a gate foundation underwater crack desilting detector, which solves the problem that cracks in the gate bottom foundation cannot be detected in the past, eliminates safety hazards, and ensures the normal operation of the gate and water conservancy project.
[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0007] The cover is placed on the bottom foundation of the gate by operating the operating lever, and high-pressure water is provided by a high-pressure water pump. The high-pressure water enters the annular channel through the drainage pipe, and then enters several water inlet channels through the annular channel, and then sprays to the bottom foundation on the inside of the cover through the water spray holes, so as to blow away the silt on the bottom foundation of the cover, and the water and silt are discharged from the sewage pipe to the outside of the cover through the one-way valve. After the silt in the cover is completely discharged, the water in the cover is clear and stable and does not flow. The camera shoots the bottom foundation in the cover and transmits the image to the external controller. The image of the bottom foundation is observed by the controller to detect cracks on the bottom foundation of the gate.
[0008] The cover body is in a frustum shape.

Specific implementation method:
[0022] In order to clearly illustrate the technical features of the present solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.
[0023] like Figure 1-2 As shown, a gate foundation underwater crack desilting detector comprises a cover body 1, the cover body 1 is closed at the top and open at the bottom, an annular channel 2 is arranged in the top plate of the cover body 1, the annular channel 2 is connected to a drain pipe 3, the drain pipe 3 is connected to a high-pressure water pump 4, a plurality of water inlet channels 5 are arranged in the circumferential direction in the side wall of the cover body 1, the top of the water inlet channel 5 is connected to the annular channel 2, the bottom of the water inlet channel 5 is provided with a water spray hole 6 facing the inner side of the cover body, a sewage pipe 7 is arranged at the top of the cover body 1, a one-way valve 8 is arranged in the sewage pipe 7, an operating rod 9 is connected to the top of the cover body 1, the operating rod 9 is used to control the movement of the cover body 1, a camera 10 and a lighting lamp 23 are arranged on the top of the inner side of the cover body 1, the camera 10 needs to be a waterproof camera to adapt to the underwater environment in the cover body 1, the lighting lamp 23 is used to illuminate the cover body, and the camera 10 and the lighting lamp 23 are connected to an external controller through a wire;
[0024] The cover body 1 is placed on the bottom foundation 11 of the gate by controlling the operating lever 9, and high-pressure water is provided by the high-pressure water pump 4. The high-pressure water enters the annular channel 2 through the drainage pipe 3, and then enters the plurality of water inlet channels 5 through the annular channel 2, and then is sprayed onto the bottom foundation 11 inside the cover body 1 through the water spray hole 6, so as to blow away the silt on the bottom foundation 11 inside the cover body 1, and the water and silt are discharged from the sewage pipe 7 to the outside of the cover body through the one-way valve 8. After the silt in the cover body 1 is completely discharged, the water in the cover body 1 is clear and stable and does not flow. The camera 10 shoots the bottom foundation inside the cover body 1 and transmits the image to the external controller. The image of the bottom foundation is observed by the controller to detect cracks on the bottom foundation 11 of the gate.
[0025] The cover body 1 is in the shape of a truncated cone with a large bottom area to increase the shooting range.
[0026] The operating rod 9 is a telescopic rod so as to adjust the length. Before working, the length of the operating rod can be adjusted according to the approximate depth of the bottom foundation.
[0027] The top of the operating rod 9 is connected to a slide 13, and the slide 13 is connected to a driving mechanism, which includes a lifting seat installed on the two side foundations 12, a lead screw 15 is installed between the two lifting seats through a bearing seat 14, one end of the lead screw 15 is connected to a driving motor 16 installed on the lifting seat, and a guide rod 17 is fixedly installed between the two lifting seats, and the slide 13 is sleeved on the outside of the lead screw 15 and the guide rod 17, and the slide 13 is threadedly connected with the lead screw 15, and the slide 13 is slidably sleeved with the guide rod 17. When the driving motor 16 is working, it drives the lead screw 15 to rotate, and when the lead screw 15 rotates, it drives the slide 13 to move along the guide rod 17, thereby driving the operating rod 9 and the bottom cover 1 to translate, and various parts of the bottom foundation 11 of the gate are detected.
[0028] The lifting seat includes an outer telescopic shell 18 , in which an electric lifting rod 19 is arranged. The height of the telescopic shell 18 can be adjusted by extending or shortening the electric lifting rod 19 .
[0029] A wear-resistant sealing ring 20 is fixedly installed on the outer edge of the bottom of the cover body 1. The wear-resistant sealing ring 20 contacts and seals with the bottom base 11 to prevent external water from entering the cover body through the gap at the bottom of the cover body, thereby ensuring the stability of water in the cover body.
[0030] The bottom of the cover is provided with a contact sensor 21, which is connected to the controller signal. When the electric lifting rod 19 adjusts the height, after the contact sensor 21 contacts the bottom base 11, the contact sensor 21 sends a signal to the controller, and the controller controls the electric lifting rod 19 to stop adjusting. At this time, the bottom of the cover 1 just contacts the bottom base 11, and the height adjustment is completed.
[0031] The water spray hole 6 is a conical water spray hole that gradually shrinks from the outside to the inside, forming a high-pressure nozzle to increase the water spray pressure.
[0032] The operating rod 9 is a hollow rod, and the wire of the camera 10 is led from the inside of the operating rod 9 to the outside.
[0033] The high-pressure water pump 4 is arranged on the foundations 12 on both sides, and the water inlet pipe 22 of the high-pressure water pump 4 is connected with the water in the channel, so that water can be easily taken and the recycling and comprehensive utilization of water can be realized.
[0034] Working principle:
[0035] When the present invention is in use, for gates with narrow width, the staff can directly hold the operating lever 9 and extend the cover body 1 to the bottom foundation 11 of the gate for inspection. For gates with wider width, it is necessary to use the driving mechanism of the present invention to drive the operating lever 9 and the cover body 1 to move and inspect various parts of the bottom foundation of the gate. Before work, the cover body 1 is lowered to the bottom foundation 11 by the operating lever 9. The wear-resistant sealing ring 20 at the bottom of the cover body 1 contacts and seals with the bottom foundation 11. Then the high-pressure water pump 4 is started. The water in the channel enters the high-pressure water pump 4 through the water inlet pipe 22. After being pressurized in the high-pressure water pump 4, it is discharged to the annular channel 2 at the top of the cover body 1 through the drainage pipe 3, and then enters several water inlet channels 5 through the annular channel 2. Finally, it is sprayed to the bottom foundation 11 on the inside of the cover body 1 through the water spray hole 6, so that the silt on the bottom foundation 11 inside the cover body 1 is blown away. Water and silt are discharged from the sewage pipe 7 through the one-way valve 8 to the bottom foundation 11. The silt in the cover body 1 is discharged outside, and after the silt in the cover body 1 is completely discharged, the water in the cover body 1 is clear and stable and does not flow. The lighting lamp 23 illuminates the cover body, and the camera 10 shoots the bottom foundation 11 in the cover body 1 and transmits the image to the external controller. The staff observes the image of the bottom foundation 11 through the controller to determine whether there are cracks on the bottom foundation 11 and determine the size of the cracks, thereby accurately detecting the cracks on the bottom foundation 11 of the gate, and confirming whether the bottom foundation 11 needs to be repaired based on the detection results, thereby eliminating safety hazards.
[0036] The above specific implementation manner cannot be used as a limitation on the protection scope of the present invention. For those skilled in the art, any substitution, improvement or change made to the implementation manner of the present invention falls within the protection scope of the present invention.
[0037] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
