Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] First embodiment

[0035] Regular monitoring of the structural health of the dam in order to promptly detect potential safety hazards is extremely important for the safety of the dam. Since there is a certain gap between the current detection instrument and the dam surface during detection, the reliability of the detection results may be affected. In order to push the detection disk 2 stably and accurately to the dam surface, the accuracy of the detection data is improved. Figure 1 、 Figure 2 、 Figure 5 and Figure 7 As shown, this embodiment provides a mobile multifunctional detection equipment for hidden dangers in dams, which is composed of a detection trolley 1, a detection disc 2, a detection needle 3 and a telescopic mechanism 4. The detection disc 2 is detachably arranged at the inner bottom of the detection trolley 1 and is used to detect cracks and cavities inside the dam. The detection needle 3 is detachably fixed to the bottom of the detection disc 2. The bottom of the detection needle 3 is set to be conical, and the number of the detection needles 3 is set to four and distributed in a circular array. An annular blade is integrally formed on the outer wall of the bottom, so that the detection needle 3 can be rotated while descending and directly drilled into the surface of the dam, without the need to manually insert and remove the detection needle 3, or to dig a detection hole in advance.

[0036] The detection vehicle 1 can be installed on the vehicle body through the connecting parts, so as to quickly move the detection vehicle 1 to the appropriate detection position. At the same time, a detection receiver can be placed on the vehicle body to receive and display the data transmitted from the detection dam, and record it in real time for remote monitoring and analysis, which is also convenient for staff to operate.

[0037] In order to ensure that the detection needle 3 is stably inserted into the surface of the dam, effectively avoid errors in manual operation, and make automated operation more convenient, the telescopic mechanism 4 is arranged on the inner side of the detection trolley 1, and is used to push it out after the detection disk 2 is released to allow the detection needle 3 to be inserted into the surface of the dam. The telescopic mechanism 4 includes a cross bracket 41 that is detachably arranged on the top of the detection disk 2, which is convenient for subsequent disassembly, inspection and maintenance of the detection disk 2. Four movable blocks 42 are distributed in a circular array at the bottom of the cross bracket 41, and one end of the movable block 42 passes through the side wall of the detection trolley 1 and is slidably connected thereto. One end of the movable block 42 is slidably provided with a limiting shell 43 fixed to the outer wall of the detection trolley 1. The top end of the movable block 42 contacts the bottom of the detection disk 2 to support the detection disk 2 so that it remains stable when not in use.

[0038] The inner side of the detection trolley 1 is also provided with a transmission component 46 that first drives the movable stopper 42 through the moving component 44 to limit the detection disk 2, and then pushes the detection disk 2 downward through the pushing component 45. The transmission component 46 includes a movable ring body 461 for transmission arranged at the top of the cross bracket 41, and a support ring body 462 is rotatably arranged at the bottom of the movable ring body 461, and four connecting rods distributed in a circumferential array and fixed to the inner wall of the detection trolley 1 are fixed on the outside of the support ring body 462. A servo motor 463 is fixedly installed on the inner top of the detection trolley 1, and a transmission gear 464 is fixed at the output shaft of the servo motor 463. One side of the transmission gear 464 is meshed with an internal gear 465 fixed to the inner side of the movable ring body 461.

[0039] The output shaft of the servo motor 463 drives the transmission gear 464 to rotate, and the transmission gear 464 drives the movable ring body 461 to rotate through the internal gear 465. The movable ring body 461 rotates more stably on the support ring body 462, ensuring effective detection of potential underground hidden dangers. At the same time, the detection needle 3 can adjust the insertion depth according to different conditions of the dam surface and can adapt to different complex conditions on the dam surface.

[0040] Second embodiment

[0041] In order to keep the detection disk 2 stable when not in use and extend the service life of the detection disk 2, Figure 3 and Figure 4 As shown, in this embodiment, a moving component 44 for synchronously driving the four movable blocks 42 to move away from the bottom of the detection disk 2 is provided on the inner side of the detection trolley 1. The specific implementation method is that the moving component 44 includes a movable connecting rod 441 respectively provided on the top of the four movable blocks 42, a gear 442 is fixed on the top of the movable connecting rod 441, and one side of the gear 442 is meshed with an arc-shaped rack 443 fixed to the outer side wall of the movable ring body 461, and the two ends of the movable connecting rod 441 are respectively rotatably provided with a gear 443 fixed to the outer side wall of the movable ring body 461. The bearing seat is fixed on the side wall, and a gear 2 444 is fixed to the bottom of the movable connecting rod 441. A transmission rack 445 fixed to the movable stopper 42 is provided on one side of the gear 2 444. When the movable ring body 461 rotates, the arc-shaped rack 443 is driven to rotate. The arc-shaped rack 443 drives the movable connecting rod 441 to rotate through the gear 1 442. The movable connecting rod 441 drives the gear 2 444 at its bottom to rotate. The gear 2 444 drives the movable stopper 42 to slide toward the inside of the limit shell 43 through the transmission rack 445.

[0042] In order to ensure that the detection disc 2 is stably pushed out from the detection trolley 1 and the detection needle 3 is inserted into the surface of the dam, potential structural problems can be accurately located. A pushing component 45 is provided on the top of the cross bracket 41 for pushing the detection disc 2 downward to contact the dam surface for hidden danger detection. The pushing component 45 includes a bidirectional screw 451 provided on the top of the movable ring body 461, and the two ends of the bidirectional screw 451 are rotatably connected to the inner wall of the detection trolley 1 through bearings. A driving gear 452 is fixedly installed on one end of the bidirectional screw 451, and a movable rack 453 matching the driving gear 452 is fixed on the top of the movable ring body 461. The movable rack 453 is spaced apart from the driving gear 452. After the ring body 461 rotates a certain angle, the movable rack 453 contacts the driving gear 452 and drives it to rotate. The top two ends of the cross bracket 41 are respectively provided with movable support rods 454, and the bottom of the movable support rod 454 is hingedly provided with a limit seat 455 fixed to the cross bracket 41. The top of the movable support rod 454 is hingedly provided with a sliding seat 456. When the two sliding seats 456 move to both ends respectively, they push the top of the movable support rod 454 to move, so that the inclination angle of the movable support rod 454 changes, thereby driving the bottom of the movable support rod 454 to move downward, and pushing the cross bracket 41 downward through the limit seat 455, thereby driving the detection plate 2 to move downward.

[0043] The two ends of the bidirectional screw 451 pass through the two sliding seats 456 and are threadedly connected to them. The top of the bidirectional screw 451 is provided with a limiting rail 457 fixed to the detection trolley 1, and the two sliding seats 456 slide on the inner sides of the two ends of the limiting rail 457, which can ensure that the two sliding seats 456 are more stable when moving.

[0044] Third embodiment

[0045] In order to ensure that the probe can be stably inserted into the dam surface for detection, the accuracy of the detection data is improved, such as Figure 5As shown, in this embodiment, a rotating component 48 is further provided at the top of the cross bracket 41 for driving the detection needle 3 to rotate when it descends. The specific implementation method is that the rotating component 48 includes a movable vertical shaft 481 that is respectively threaded on the top of the four detection needles 3, and a limited vertical tube 482 is slidably provided on the top of the movable vertical shaft 481. The top of the movable vertical shaft 481 passes through the detection plate 2 and the cross bracket 41 and extends to the limited vertical tube 482. Vertical grooves are provided on both sides of the limited vertical tube 482. The top of the movable vertical shaft 481 is respectively provided with There are protrusions that slide with the two vertical grooves, so that the movable vertical shaft 481 can only slide and cannot rotate in the limiting vertical tube 482. The top of the limiting vertical tube 482 is provided with a positioning cross bar fixed to the support ring body 462 through a bearing rotation. The positioning cross bar provides support for the limiting vertical tube 482 to ensure that the limiting vertical tube 482 can rotate stably. The top of one of the limiting vertical tubes 482 is fixedly connected to the transmission gear 464, and the tops of the remaining three limiting vertical tubes 482 are respectively fixed with driven gears 483 that mesh with the internal gear 465.

[0046] When the inner gear 465 rotates, it drives the three transmission gears 464 to rotate, and drives the limiting vertical pipe 482 at the bottom thereof to start rotating. The transmission gear 464 also drives the limiting vertical pipe 482 at the bottom thereof to rotate. The four limiting vertical pipes 482 rotate at the same time, and drive the detection needle 3 to rotate and drill into the surface of the dam through the bottom movable vertical shaft 481, making it more convenient to insert the detection needle 3 into the ground. There is no need to manually insert and remove the detection needle 3, or to pre-dig a detection hole for the detection needle 3 to insert, which improves the efficiency of the detection work, allows continuous work for a long time, and reduces the pause time.

[0047] Fourth embodiment

[0048] In order to effectively reduce the impact or friction of the detection plate 2 during operation, Figure 6 As shown, in this embodiment, a protective component 47 is further provided on the cross bracket 41 to prevent the detection disc 2 from directly hitting the ground. The specific implementation method is that the protective component 47 includes a supporting vertical tube 471 fixed to the four corners of the bottom of the cross bracket 41, and a movable vertical rod 472 is slidably provided at the bottom of the supporting vertical tube 471. The top of the movable vertical rod 472 is fixed with a buffer spring 473 located in the supporting vertical tube 471 and fixed thereto. When the detection disc 2 moves downward, after the detection needle 3 is inserted into the ground, the movable vertical rod 472 at the four corners of the bottom of the cross bracket 41 contacts the ground, and the movable vertical rod 472 squeezes the buffer spring 473 upward. The buffer spring 473 produces elastic deformation and is compressed, thereby avoiding damage caused by the detection disc 2 directly colliding with the ground, thereby extending the service life of the detection disc 2.

[0049] The present invention first synchronously drives the four movable blocks 42 to move into the corresponding limit housings 43 through the transmission component 46, and the movable blocks 42 are moved away from the bottom of the detection disk 2, so that the detection disk 2 has no limit, and then the detection disk 2 is pushed downward by the pushing component 45, and the detection needle 3 at the bottom of the detection disk 2 is rotated and inserted into the surface of the dam, and then the hidden dangers of the dam are detected, which improves the accuracy of the detection data. This can effectively avoid errors in manual operation, and the automated operation is more convenient, which improves the efficiency of the detection work.

[0050] The servo motor 463 is then started, and the output shaft of the servo motor 463 drives the transmission gear 464 at its bottom to rotate, and the transmission gear 464 drives the internal gear 465 meshing with it to rotate, and the internal gear 465 drives the movable ring body 461 on its outer side to rotate on the support ring body 462, and the movable ring body 461 first drives the four arc-shaped racks 443 on its outer side to rotate, and the four arc-shaped racks 443 respectively drive the gear 1 442 meshing with it to rotate, and the gear 1 442 drives the movable connecting rod 441 at its bottom to rotate, and the movable connecting rod 441 drives the gear 2 444 at its bottom to start rotating, and the gear 2 444 drives the transmission rack 445 on one side to move, and the transmission rack 445 drives the movable stopper 42 to pass through the side wall of the detection trolley 1 to slide toward the inside of the limit housing 43, and the movable stopper 42 moves away from the bottom of the detection disk 2, so that the detection disk 2 lacks a limit;

[0051] At the same time, the arc-shaped rack 443 is completely separated from the gear 1 442, and at this time the movable rack 453 contacts the driving gear 452 and drives it to rotate. The driving gear 452 drives the bidirectional screw 451 at its axis to rotate, and the bidirectional screw 451 drives the two sliding seats 456 to move to both ends. The sliding seat 456 pushes the top of the movable support rod 454 to move, so that the inclination angle of the movable support rod 454 changes, thereby driving the bottom of the movable support rod 454 to move downward, and the cross bracket 41 is pushed downward by the limit seat 455. The cross bracket 41 drives the detection plate 2 and the detection needle 3 at the bottom thereof to move downward;

[0052] At the same time, the detection needle 3 drives the movable vertical shaft 481 at its top to move downward, and when the internal gear 465 rotates, it drives the three transmission gears 464 to rotate at the same time. The three transmission gears 464 respectively drive the limiting vertical pipe 482 at the bottom to start rotating, and the transmission gear 464 also drives the limiting vertical pipe 482 at the bottom to rotate, so that the four limiting vertical pipes 482 rotate at the same time, and the limiting vertical pipe 482 drives the movable vertical shaft 481 at the bottom to start rotating as well. The movable vertical shaft 481 at its bottom drives the detection needle 3 to drill into the surface of the dam, and then the hidden dangers of the dam can be detected.

[0053] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
