DETAILED DESCRIPTION

[0025] The following describes in detail a protective fence for water conservancy construction provided by the present invention, with reference to the accompanying drawings and specific embodiments. It is also noted that, to provide a more detailed description of the embodiments, the following examples are listed as best and preferred embodiments. Those skilled in the art may also employ alternative implementations for some known technologies. Furthermore, the accompanying drawings are provided solely for the purpose of describing the embodiments in greater detail and are not intended to limit the present invention.

[0026] like Figure 1 、 Figure 2 and Figure 4As shown, the embodiment of the present invention provides a protective fence for water conservancy construction, comprising: a positioning plate 1, the top of the positioning plate 1 is rotatably connected to a fence body 2; a square groove 101 is provided on the top of the positioning plate 1, and a motor 102 for providing driving force is fixedly installed on the inner wall of the positioning plate 1, and a screw rod 103 is fixedly installed on the end of the output shaft of the motor 102, and the end of the screw rod 103 away from the motor 102 is rotatably connected to the inner wall of the square groove 101, and a movable ring 104 is threadedly connected to the outer wall of the screw rod 103; a groove 201 is provided on the side of the fence body 2 close to the positioning plate 1, and a positioning frame 202 is fixedly installed on the inner wall of the groove 201, and the inner wall of the positioning frame 202 is rotatable. It is connected to a rotating rod 203, and the outer wall of the rotating rod 203 is slidably connected to the moving rod 204. The outer wall of the rotating rod 203 is provided with a fixing hole 205. The outer wall of the moving rod 204 is threadedly connected to a fixing bolt 206, and the fixing bolt 206 passes through the moving rod 204 and is threadedly connected to the fixing hole 205. The end of the moving rod 204 away from the rotating rod 203 is connected to the moving ring 104 through the positioning pin 3, and the groove 201 is adapted to the size of the square groove 101. By limiting the square groove 101 and the groove 201, it is beneficial that when the positioning plate 1 overlaps with the fence body 2, the groove 201 can cover the square groove 101, thereby making the positioning plate 1 and the fence body 2 fit more closely.

[0027] like Figure 1 and Figure 3 As shown, the positioning pin 3 includes a pin shaft 301 that passes through the movable ring 104 and the movable rod 204. The inner wall of the pin shaft 301 is threadedly connected with a positioning shaft 302. The end of the positioning shaft 302 away from the pin shaft 301 is fixedly assembled with a positioning block 303. By setting the positioning pin 3, it is beneficial to connect the movable ring 104 and the movable rod 204, thereby improving its flexibility and facilitating the folding of the positioning plate 1 and the fence body 2 by removing the positioning pin 3 during movement.

[0028] like Figure 1 and Figure 2 As shown, the bottom of the positioning plate 1 is fixedly equipped with a fixing nail 105, and the outer wall of the fixing nail 105 is fixedly equipped with a barb 106. By setting the fixing nail 105 and the barb 106, it is beneficial to increase the friction between the contact surface between the positioning plate 1 and the slope, thereby improving the stability of the device in protection and ensuring its protection effect.

[0029] like Figure 1 and Figure 2 As shown, fixing grooves 107 are provided on both sides of the positioning plate 1, and the inner wall of the fixing groove 107 is fixedly equipped with a hanging ring 108. By setting the fixing groove 107 and the hanging ring 108, it is convenient to change the position of the device through the hanging ring 108, thereby improving its convenience.

[0030] like Figure 1 and Figure 2As shown, a through hole 207 is opened on the outer wall of the fence body 2, and a protective railing 208 is fixedly installed on the inner wall of the through hole 207. By setting the through hole 207 and the protective railing 208, it is beneficial to reduce the weight of the fence body 2 while ensuring its protective effect and improving its aesthetics.

[0031] The technical solution provided by the present invention is that when working, by rotating the fence body 2, the rotating rod 203 on the fence body 2 is rotated in the direction of the positioning plate 1, and then the moving rod 204 is pulled out, the end of the moving rod 204 is clamped with the top of the moving ring 104, the pin shaft 301 is inserted therein, and the moving rod 204 is connected to the moving ring 104 with the positioning shaft 302, and then the rotating rod 203 and the moving rod 204 are fixed with the fixing bolt 206. At this time, the screw rod 103 can be driven to rotate by the motor 102, thereby driving the moving ring 104 to move horizontally, and the movement of the moving ring 104 drives the moving rod 204 to move, thereby adjusting the angle of the fence body 2, which is conducive to adjusting the angle of the fence body 2 according to the actual slope of the slope.

[0032] The provision of the fixing nails 105 and the barbs 106 is conducive to increasing the friction between the contact surface of the positioning plate 1 and the slope, thereby improving the stability of the device in protection and ensuring its protection effect.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
