Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] This application discloses an electronic fence for a drinking water source protection area. (Refer to...) Figure 1 , Figure 2 and Figure 3 An electronic fence for a drinking water source protection area includes an electronic fence body 1, and an extension mechanism 2 is provided at the bottom of the electronic fence body 1.

[0027] The extension mechanism 2 includes a fixed plate 201, the inner cavity of which is movably connected to the bottom surface of the electronic fence body 1. There are two fixed plates 201. A rotating plate 202 is rotatably connected to the top of the fixed plate 201. A movable rod 208 is movably connected inside the rotating plate 202. There are three movable rods 208. A movable plate 205 is fixedly connected to the bottom of the movable rod 208. An expansion plate 206 is fixedly connected to one side of the movable plate 205. The surface of the expansion plate 206 is movably connected to the inner cavity of the fixed plate 201.

[0028] Reference Figure 2 and Figure 3 The top of the moving rod 208 is fixedly connected to a limiting block 204, and the bottom of the limiting block 204 is movably connected to the top of the rotating disk 202. By setting the limiting block 204, and the diameter of the limiting block 204 being larger than the diameter of the moving rod 208, the movement of the moving rod 208 is limited, so as to prevent the moving rod 208 from detaching from the interior of the rotating disk 202 during operation.

[0029] Reference Figure 2 and Figure 3 A guide groove 209 is provided on one side of the fixed disk 201, and a moving groove 203 is provided on one side of the rotating disk 202. The inner cavities of both the guide groove 209 and the guide groove 203 are movably connected to the surface of the moving rod 208. With the moving groove 203 provided, and the diameter of the moving rod 208 being the same as the diameter of the moving groove 203, the moving rod 208 can move seamlessly inside the fixed disk 201. At the same time, the movement of the moving rod 208 is guided to prevent it from deviating. With the guide groove 209 provided, the movement of the moving rod 208 is limited to prevent it from deviating from the path during movement. This further improves the stability of the expansion plate 206 when it moves.

[0030] Reference Figure 4 An adjustment mechanism 3 is provided in the inner cavity of the fixed plate 201. The adjustment mechanism 3 includes a moving column 301. The surface of the moving column 301 is movably connected to the inner cavity of the fixed plate 201. One end of the moving column 301 is fixedly connected to a pull plate 302. A spring 303 is slidably sleeved on one end of the surface of the moving column 301. One end of the spring 303 is fixedly connected to one side of the fixed plate 201, and the other end of the spring 303 is fixedly connected to one side of the pull plate 302. With the setting of the spring 303, when the pull plate 302 moves, the spring 303 is stretched and deformed. When the spring 303 loses its tension, it drives the moving column 301 to reset, thereby fixing the position of the fixed plate 201.

[0031] Reference Figure 4The electronic fence body 1 has a number of fixing grooves 306 on its surface. One end of the movable column 301 is inserted into the fixing groove 306. Two grooves 305 are provided on one side of the inner cavity of the electronic fence body 1. A sliding column 304 is slidably connected to the inner cavity of the groove 305. One end of the sliding column 304 is fixedly connected to one side of the fixed plate 201. The fixing grooves 306 allow the movable column 301 to move inside the electronic fence body 1 and fix the fixed plate 201 before or after the movement. The grooves 305 allow the sliding column 304 to move inside the electronic fence body 1 and guide the movement of the fixed plate 201 to prevent the fixed plate 201 from moving too far.

[0032] Reference Figure 5 and Figure 6 A fixing mechanism 4 is provided on one side of the fixed disk 201. The fixing mechanism 4 includes a fixing plate 401. One side of the fixing plate 401 is fixedly connected to one side of the fixed disk 201. An adjusting screw sleeve 402 is fixedly connected to the inner cavity of the fixing plate 401. A threaded rod 404 is threadedly connected to the inner cavity of the adjusting screw sleeve 402. A moving block 405 is fixedly connected to one end of the threaded rod 404. A turntable 403 is fixedly connected to the other end of the threaded rod 404. A fixing column 406 is fixedly connected to one side of the moving block 405. The threaded rod 404 can push the moving block 405 to move, thereby driving the fixing column 406 to fix the position of the turntable 202. The turntable 403 increases the contact area between the operator and the threaded rod 404, thereby facilitating the rotation of the threaded rod 404.

[0033] Reference Figure 5 and Figure 6 A groove 407 is provided on one side of the fixed plate 401. A guide block 408 is slidably connected to the inner cavity of the groove 407. The top of the guide block 408 is fixedly connected to the bottom of the moving block 405. The groove 407 allows the guide block 408 to move inside the fixed plate 401 and guides the movement of the guide block 408, further improving the stability of the moving block 405 during movement.

[0034] Reference Figure 2 and Figure 6 A positioning groove 207 is provided on one side of the rotating disk 202. There are multiple positioning grooves 207. The surface of the fixing post 406 is inserted into the inner cavity of the positioning groove 207. By setting the positioning groove 207, the fixing post 406 can move inside the rotating disk 202, thereby fixing the rotating disk 202 before or after rotation and preventing the rotating disk 202 from rotating back.

[0035] Working Principle: The front-end accessories of the electronic fence mainly consist of poles, insulators, wires, audible and visual alarms, and surge arresters. The operator installs the electronic fence body 1 on the ground (this is existing technology). Then, by pulling the pull plate 302 outwards, the moving column 301 moves. When the pull plate 302 moves, the spring 303 is stretched and deformed. After the moving column 301 disengages from the fixing groove 306, the fixing plate 201 is pulled, causing one side of the fixing plate 201 to fit tightly against the ground. Simultaneously, the sliding column 304 moves within the groove 305. At this point, the groove 305 limits the movement of the fixing plate 201, preventing excessive movement. After the spring 303 loses its tension, the moving column 301 is inserted into the fixing groove 306, securing the used fixing plate 201. Finally, rotating the moving groove 203 rotates the threaded rod 404. The moving block 405 is moved by adjusting the threaded connection between the screw sleeve 402 and the threaded rod 404. The moving block 405 drives the fixed column 406 to move, causing the fixed column 406 to disengage from the positioning groove 207. Then, the moving rod 208 is moved by rotating the rotating disk 202. One end of the moving rod 208 moves from one side to the other side inside the moving groove 203, while the other end of the moving groove 203 moves from one side to the other side of the guide groove 209. The moving rod 208 drives the moving plate 205 to move, and the moving plate 205 drives the moving rod 208 to move, causing the moving rod 208 to expand outward and increase the contact range between the electronic fence body 1 and the ground. Finally, the threaded rod 404 is rotated by rotating the rotating disk 403. The moving block 405 is moved by adjusting the threaded connection between the screw sleeve 402 and the threaded rod 404. The moving block 405 drives the fixed column 406 to fit into the positioning groove 207, fixing the rotated disk 202.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
