[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] First Embodiment

[0035] Regularly monitoring the structural health of the dam to timely detect possible 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, which may affect the reliability of the detection results. In order to stably and accurately push the detection disc 2 to the dam surface and improve the accuracy of the detection data, as Figure 1 , Figure 2 , Figure 5 and Figure 7 shown, this embodiment provides a multi-functional mobile detection equipment for dam hidden dangers, 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 at the bottom of the detection disc 2. The bottom of the detection needle 3 is conical, and the number of detection needles 3 is set to four and is distributed in a circumferential array. An annular blade is integrally formed on the outer side wall of its bottom, so that when the detection needle 3 descends, it rotates and directly drills into the dam surface without manually inserting and pulling out the detection needle 3, or pre-digging a detection hole.

[0036] The detection trolley 1 can be installed on the vehicle body through a connecting piece to facilitate quickly moving the detection trolley 1 to a suitable 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 detected dam, and record it in real time for remote monitoring and analysis, and it is also convenient for the staff to operate.

[0037] In order to ensure that the detection needle 3 is stably inserted into the dam surface, effectively avoid errors in manual operation, and make the automatic operation more convenient, the telescopic mechanism 4 is arranged inside the detection trolley 1 and is used to push out the detection disc 2 after removing the limit of the detection disc 2 so that the detection needle 3 is inserted into the dam surface. The telescopic mechanism 4 includes a cross bracket 41 detachably arranged on the top of the detection disc 2, which is convenient for subsequent disassembly, inspection and maintenance of the detection disc 2. Four circumferentially arrayed movable stoppers 42 are arranged at the bottom of the cross bracket 41, and one end of the movable stopper 42 penetrates through the side wall of the detection trolley 1 and is slidably connected thereto. A limit housing 43 fixed to the outer side wall of the detection trolley 1 is slidably arranged at one end of the movable stopper 42. One end of the top of the movable stopper 42 is in contact with the bottom of the detection disc 2 to support the detection disc 2 and keep it stable when not in use.

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

[0039] The output shaft of the servo motor 463 drives the transmission gear 464 to rotate. 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 hazards. At the same time, the detection needle 3 can adjust the insertion depth according to different conditions on the surface of the dam and can adapt to different complex conditions on the surface of the dam.

[0040] Second Embodiment

[0041] In order to keep the detection disc 2 stable when not in use and extend the service life of the detection disc 2, as Figure 3 and Figure 4 shown, in this embodiment, a moving component 44 for synchronously driving the four movable stoppers 42 to move away from the bottom of the detection disc 2 is arranged on the inner side of the detection trolley 1. The implementation method is specifically that the moving component 44 includes movable connecting rods 441 respectively arranged on the tops of the four movable stoppers 42. A gear one 442 is fixed to the top of the movable connecting rod 441. An arc-shaped rack 443 fixed to the outer side wall of the movable ring body 461 is meshed on one side of the gear one 442. Bearing seats fixed to the inner side wall of the detection trolley 1 are rotatably arranged at both ends of the movable connecting rod 441. A gear two 444 is fixed to the bottom of the movable connecting rod 441. A transmission rack 445 fixed to the movable stopper 42 is meshed on one side of the gear two 444. When the movable ring body 461 rotates, it drives the arc-shaped rack 443 to rotate. The arc-shaped rack 443 drives the movable connecting rod 441 to rotate through the gear one 442. The movable connecting rod 441 drives the gear two 444 at its bottom to rotate. The gear two 444 drives the movable stopper 42 to slide inward along the inner side of the limit housing 43 through the transmission rack 445.

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

[0043] Both ends of the bidirectional screw 451 respectively penetrate through the two sliding seats 456 and are threadedly connected thereto. A limit cross rail 457 fixed to the detection trolley 1 is provided at the top of the bidirectional screw 451, and the two sliding seats 456 respectively slide inside both ends of the limit cross rail 457, which can ensure that the two sliding seats 456 are more stable when moving.

[0044] Third Embodiment

[0045] To ensure that the detection needle can be stably inserted into the dam surface for detection and improve the accuracy of the detection data, as Figure 5As shown in the figure, in this embodiment, a rotating member 48 for driving the probe needle 3 to rotate when it descends is further provided at the top of the cross bracket 41. Specifically, the rotating member 48 includes movable vertical shafts 481 respectively threadedly provided at the tops of the four probe needles 3. A limiting vertical tube 482 is slidably provided at the top of the movable vertical shaft 481, and the top of the movable vertical shaft 481 penetrates through the detection disk 2 and the cross bracket 41 and extends into the limiting vertical tube 482. Vertical grooves are formed on both sides of the limiting vertical tube 482, and protrusions respectively sliding with the two vertical grooves are provided on both sides of the top of the movable vertical shaft 481, so that the movable vertical shaft 481 can only slide but not rotate in the limiting vertical tube 482. A positioning cross bar fixed to the support ring body 462 is rotatably provided at the top of the limiting vertical tube 482 through a bearing. The positioning cross bar provides a supporting function 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 driven gears 483 meshing with the internal gear 465 are respectively fixed to the tops of the remaining three limiting vertical tubes 482.

[0046] When the internal gear 465 rotates, it drives the three transmission gears 464 to rotate, drives the limiting vertical tubes 482 at their bottoms to start rotating, and the transmission gear 464 also drives the limiting vertical tube 482 at its bottom to rotate. The four limiting vertical tubes 482 rotate simultaneously, and drive the probe needle 3 to rotate and drill into the surface of the dam through the movable vertical shaft 481 at the bottom, making it more convenient for the probe needle 3 to insert into the ground. There is no need to manually insert and remove the probe needle 3, or pre-dig a detection hole for the probe needle 3 to insert, improving the efficiency of the detection work, enabling continuous operation for a long time, and reducing the pause time.

[0047] Fourth Embodiment

[0048] In order to effectively reduce the impact or friction suffered by the detection disk 2 during the working process, as Figure 6 shown in the figure, in this embodiment, a protection member 47 for preventing the detection disk 2 from directly hitting the ground is further provided on the cross bracket 41. Specifically, the protection member 47 includes support vertical tubes 471 fixed at the four corners of the bottom of the cross bracket 41. A movable vertical rod 472 is slidably provided at the bottom of the support vertical tube 471. A buffer spring 473 fixed inside the support vertical tube 471 and fixed to it is fixedly provided at the top of the movable vertical rod 472. When the detection disk 2 moves downward and the probe needle 3 inserts into the ground, the movable vertical rods 472 at the four corners of the bottom of the cross bracket 41 contact the ground, and the movable vertical rods 472 upwardly compress the buffer spring 473. The buffer spring 473 undergoes elastic deformation and is compressed, thereby avoiding damage caused by the detection disk 2 directly colliding with the ground and extending the service life of the detection disk 2.

[0049] In the present invention, the transmission component 46 first synchronously drives the four movable stoppers 42 to move into the corresponding limit shells 43. The movable stoppers 42 are moved away from the bottom of the detection disc 2, causing the detection disc 2 to lack limitation. Then, the pushing component 45 pushes the detection disc 2 downward. The detection needle 3 at the bottom of the detection disc 2 rotates and inserts into the dam surface. Then, the detection of potential dam hazards is carried out, improving the accuracy of the detection data. This can effectively avoid errors in manual operations, and the automated operation is more convenient, improving the efficiency of the detection work.

[0050] During the actual use of the detection equipment, the detection trolley 1 is moved to the specified detection position on the dam through the vehicle body. Then, the servo motor 463 is started. The output shaft of the servo motor 463 drives the transmission gear 464 at its bottom to rotate. The transmission gear 464 drives the internal gear 465 meshing with it to rotate. The internal gear 465 drives the movable ring body 461 outside it to rotate on the support ring body 462. The movable ring body 461 first drives the four arc-shaped racks 443 outside it to rotate. The four arc-shaped racks 443 respectively drive the first gears 442 meshing with them to rotate. The first gears 442 drive the movable connecting rods 441 at their bottoms to rotate. The movable connecting rods 441 drive the second gears 444 at their bottoms to start rotating. The second gears 444 drive the transmission rack 445 on one side of them to move. The transmission rack 445 drives the movable stopper 42 to slide through the side wall of the detection trolley 1 towards the inside of the limit shell 43. The movable stopper 42 is moved away from the bottom of the detection disc 2, causing the detection disc 2 to lack limitation.

[0051] At the same time, the arc-shaped rack 443 is completely disengaged from the first gear 442. 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. The bidirectional screw 451 drives the two sliding seats 456 to move towards both ends respectively. The sliding seats 456 push the top of the movable support rod 454 to move, changing the inclination angle of the movable support rod 454, thereby driving the bottom of the movable support rod 454 to move downward. Through the limit seat 455, the cross support 41 is pushed downward. The cross support 41 drives the detection disc 2 and the detection needle 3 at its bottom to move downward.

[0052] At the same time, the detection needle 3 drives the movable vertical shaft 481 at its top to move downward. When the internal gear 465 rotates, it drives the three transmission gears 464 to rotate simultaneously. The three transmission gears 464 respectively drive the limit vertical tubes 482 at their bottoms to start rotating. And the transmission gears 464 also drive the limit vertical tubes 482 at their bottoms to rotate, causing the four limit vertical tubes 482 to rotate simultaneously. The limit vertical tubes 482 drive the movable vertical shafts 481 at their bottoms to start rotating. The movable vertical shafts 481 drive the detection needles 3 at their bottoms to drill into the dam surface. Then, the detection of potential dam hazards can be carried out.

[0053] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
