[0027] As Figures 1 to 8As shown in the figure, a dam crack detection device includes two groups of symmetric telescopic mounting brackets 1. Each group of telescopic mounting brackets 1 includes a first mounting rod 11 with a U-shaped cross-section, a second mounting rod 12 with a U-shaped cross-section, and a third mounting rod 13 with a U-shaped cross-section. A first connecting slider 14 is installed at the tail end of the first mounting rod 11, and a first multi-stage electric telescopic rod 17 is installed on the first connecting slider 14. A second connecting slider 15 is installed at the tail end of the second mounting rod 12, and a second multi-stage electric telescopic rod 18 is installed on the second connecting slider 15. A third connecting slider 16 is installed at the tail end of the third mounting rod 13. The head of the first multi-stage electric telescopic rod 17 is connected to the second connecting slider 15 with screws, and the head of the second multi-stage electric telescopic rod 18 is connected to the third connecting slider 16 with screws.

[0028] Inner sliding grooves 19 are provided on the inner sides of the first mounting rod 11, the second mounting rod 12, and the third mounting rod 13. The inner sliding groove 19 on the inner side of the first mounting rod 11 engages with the first connecting slider 14. The inner sliding groove 19 on the inner side of the first mounting rod 1 engages with the second connecting slider 15 in a sliding fit, and the inner sliding groove 19 on the inner side of the second mounting rod 12 engages with the third connecting slider 16 in a sliding fit. This improves the stability when the second mounting rod, the third mounting rod, the second connecting slider, and the third connecting slider move.

[0029] Outer sliding grooves 110 are provided at the tops of the second mounting rod 12 and the third mounting rod 13. A limit slider 111 is installed at the head of the first mounting rod 11 and the head of the second mounting rod 12 respectively. The limit slider 110 at the head of the first mounting rod 11 engages with the outer sliding groove 110 at the top of the second mounting rod 12 in a sliding fit, and the limit slider 111 at the head of the second mounting rod 12 engages with the outer sliding groove 110 at the top of the third mounting rod 13 in a sliding fit. By using the cooperation of the limit slider and the outer sliding groove, it is possible to prevent the situation where the first mounting rod and the second mounting rod, and the second mounting rod and the third mounting rod are torn apart.

[0030] A first opening 112 for the motor of the first multi-stage electric telescopic rod 17 and the first connecting slider 14 to pass through is provided at the tail of the first mounting rod 11. A second opening 113 for the motor of the second multi-stage electric telescopic rod 18 and the second connecting slider 15 to pass through is provided at the tail of the second mounting rod 12. A third opening 114 for the third connecting slider 16 to pass through is provided at the tail of the third mounting rod 13.

[0031] A plurality of cameras 2 for taking images of the dam surface are installed at the bottom of each group of telescopic mounting brackets 1. Two cameras 2 are installed at the bottom of each of the first mounting rod 11, the second mounting rod 12, and the third mounting rod 13.

[0032] The first multi-stage electric telescopic rod drives the second mounting rod to move relative to the first mounting rod, thereby adjusting the positional relationship between the second mounting rod and the first mounting rod, and further adjusting the distance between the camera at the bottom end of the second mounting rod and the camera at the bottom end of the first mounting rod; the second multi-stage electric telescopic rod drives the third mounting rod to move relative to the second mounting rod, thereby adjusting the positional relationship between the third mounting rod and the second mounting rod, and further adjusting the distance between the camera at the bottom end of the third mounting rod and the camera at the bottom end of the second mounting rod.

[0033] The two sets of telescopic mounting frames 1 are connected via a docking frame 3 , and the docking frame 3 , the tail end of the first mounting rod 11 , and the first connecting slider 14 are connected by screws.

[0034] An end block 5 is mounted on one end of the telescopic mounting frame 1 away from the docking frame 3 , and the end block 5 is mounted on the head of the third mounting rod 13 .

[0035] The rear end of the docking frame 3 is fixed with a first U-shaped ring 31 for tying a traction rope, the rear end of the second connecting slider 15 is fixed with a second U-shaped ring 115 for tying a traction rope, and the rear end of the third connecting slider 16 is fixed with a third U-shaped ring 116 for tying a traction rope.

[0036] A first caster 4 is mounted on the bottom end of the docking frame 3, and a second caster 6 is mounted on the bottom end of the end block 5. The first and second casters work together to improve the stability of the dam crack detection device as it moves along the dam surface. Both the first and second casters 4 and 6 are fixed casters, each comprising a support rod 7 with a cross-shaped cross-section, a U-shaped caster frame 8, and a caster 9. The top end of the support rod 7 is fixedly connected to the bottom end of the docking frame 3, and the bottom end of the support rod 7 is fixedly connected to the caster frame 8. Caster 9 is rotatably mounted in the caster frame 8 via a caster shaft.

[0037] The first caster 4 is tilted forward and downward, with the included angle between the central axis of the first caster 4 and the bottom end of the docking frame 3 being 45° to 60°, thereby reducing resistance as the dam crack detection device moves downward along the dam surface. The bottom ends of the first caster 4 and the second caster 6 are located on the same plane, parallel to the bottom end of the docking frame 3.

[0038] During the inspection, the dam crack detection device is pulled by a traction rope and moved from top to bottom (or from bottom to top) along the dam surface, and the image data of the dam surface is captured by the camera for the inspectors to analyze and judge the dam cracks.

[0039] Two sets of telescopic mounting frames are assembled together through a docking frame, and multiple cameras are installed at the bottom of the telescopic mounting frame. Multiple cameras can be used for shooting at the same time. The telescopic mounting frame is used to adjust the distance between the cameras, thereby adjusting the shooting width of the dam crack detection device, which can improve the detection efficiency of the dam crack detection device on the dam.
