Through the above structure, the detection instrument moves on the entire dam surface through the detection platform 20, which has the advantages of convenient detection, comprehensive detection area, high work efficiency, etc., does not require manual climbing of the dam surface, greatly reduces the labor intensity of detection, and eliminates the safety hazards caused by manual detection on the dam surface. Preferably, the pull wire 30 is a steel wire rope or a nylon rope.

[0048] See also Figure 2 , 3 The control device 10 includes a base 11, on which a winding drum 12 is rotatably mounted. The winding drum 12 is driven to rotate by a first motor 13, so as to retract and release the cable 30 wound on the winding drum 12. The winch system is adopted, and the cable 30 is retracted and released by the forward and reverse rotation of the winding drum 12. The structure is simple and easy to use. For easy control, the first motor 13 is a stepping motor or a servo motor.

Supports 121 are respectively provided at both ends of the winding drum 12, and the supports 121 are connected and fixed to the first vertical plate 112. Bearing seats 122 are respectively provided on the supports 121. The central axes at both ends of the winding drum 12 are respectively connected and rotated with the bearing seats 122. The central axis of the winding drum 12 located on one side of the second vertical plate 113 extends out of the bearing seat 122 and is fixedly installed with a first gear 123. The first motor 13 is installed on a side of the second vertical plate 113 away from the winding drum 12. The output shaft of the first motor 13 faces the winding drum 12, and a second gear 131 is installed on the output shaft. The second gear 131 is meshed with the first gear 123 for transmission. The second gear 131 is meshed with the first gear 123 to further reduce the rotation speed of the winding drum 12, so that the detection platform 20 can run more stably.

[0050] In order to ensure that the pull wire 30 can be wound on the winding drum 12 without being separated from the winding drum 12 when the detection platform 20 is in any position, see Figure 3 A guide device 14 for the wire 30 to pass through is installed on the base 11. The guide device 14 can be composed of four rotating shafts, the wire 30 passes through the center surrounded by the four rotating shafts, or it can be composed of two groove wheels, which can be installed up and down, or left and right.

[0051] Because the cable 30 is in an oblique pulling state most of the time, the grooved wheels 143 are installed on the left and right sides.

The two grooved wheels 143 abut against each other, and a channel 144 is formed between them for the wire 30 to pass through. In this way, no matter where the detection platform 20 is, the wire 30 can be wound on the winding drum 12 through the channel 144.

[0052] See also Figure 4 , 5 The detection platform 20 includes a base 21, a driving device 24, a mounting platform 26, and a GPS locator 40. Four universal wheels 22 are installed at the bottom of the base 21. A connecting ring 23 connected to the pull wire 30 is provided on one side of the base 21. A driving device 24 is installed on the upper side of the base 21. The driving device 24 drives the mounting platform 26 to rotate. The detection instrument for detecting the dam surface 62 is installed on the mounting platform 26. The GPS locator 40 for locating the position of the detection platform 20 is installed on the base 21. Through the universal wheels 22, the detection platform 20 can move flexibly on the inclined dam surface 62 by its own weight. The driving device 24 drives the mounting platform 26 to rotate, so that the detection instrument installed on the mounting platform 26 can scan the dam surface 62 in a 360-degree comprehensive manner. The GPS locator 40 locates the position of the detection platform 20. Because the boundary of the connection between the dam surface 62 and the surrounding mountains is called the slope line, and the slope line is generally an irregular curve, the GPS locator 40 is used to identify the position of the slope line 621. First, it is convenient for the detection platform 20 to fully detect the dam surface 62 area, and second, it is to prevent the detection platform 20 from colliding with the mountain.

The first buffer body 251 is used to fix the support shaft 252, and to reduce the shock of the mounting platform 26, and to filter the vibration caused by the universal wheel 22 when walking on the dam surface 62. Preferably, the first buffer body 251 is a rubber block, and a hole for installing a bearing is provided in the first buffer body 251, and the support shaft 252 is installed in the bearing in the first buffer body 251. The second buffer body 254 is a cylindrical sponge with a certain hardness, such as EVA foam, which further reduces the bumps of the detection platform 20 during movement due to the instability of the dam surface 62, and avoids damage to the detection instrument. The mounting platform 26 is connected to the second buffer body 254 through high-strength glue, or connected to the fourth gear 253 through bolts passing through the second buffer body 254. At the same time, in order to prevent the detection platform 20 from colliding with foreign objects during movement, thereby causing damage to the detection instrument, protective plates 29 are installed on both sides of the base 21 to protect the detection instrument. Preferably, the second motor 241 is a stepper motor or a servo motor for easy control.
