[0002] Well irrigation is widely used in plains areas and is a major method of agricultural irrigation. Due to its good irrigation effect, well irrigation is also widely used in the north where rainfall is low. To prevent animals and pedestrians from falling into the irrigation well, protective devices are usually installed at the wellhead.

[0003] The existing Chinese patent 201920236055.0 proposes a wellhead protection device for farmland irrigation wells. The through hole in this application can prevent people from falling into the well. However, some small animals or floating garbage may fall into the well through the wellhead. The death and decomposition of animals will pollute the water source and easily breed bacteria. They can easily cause infection when pumping water, which is inconvenient for users and reduces the practicality of the protection device. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a protective device for farmland irrigation wells, which has the advantage of preventing animals and garbage from entering. This solves the problem of the wellhead protection device for farmland irrigation wells proposed in the existing Chinese patent 201920236055.0. While the through hole of that application can prevent people from falling into the well, some small animals or floating garbage may fall into the well through the wellhead.

A first spring is fixedly connected inside the lock cylinder. A sliding plate is fixedly connected to the bottom of the first spring and is slidably connected to the lock cylinder. A pin is fixedly connected to the bottom of the sliding plate, and the rear side of the pin is set as an inclined surface. A second fixing plate is fixedly connected to the left side of the well casing. An insertion hole is opened on the surface of the second fixing plate. The bottom end of the pin is located inside the insertion hole and is slidably connected to it. A groove is opened on the left side surface of the lock cylinder. A dial plate is fixedly connected to the left side of the sliding plate. The groove is located inside the dial plate and is slidably connected to it.

[0006] In a preferred embodiment of this utility model, connecting plates are fixedly connected to both ends of the right side of the well casing, and second springs are fixedly connected to both ends of the back side of the front connecting plate. A movable plate is fixedly connected to the rear end of the second spring. A rope hole is passed through the front side of the rear connecting plate, and a steel wire rope is fixedly connected to the back side of the movable plate. The steel wire rope extends to the back side of the well casing through the rope hole. A back plate is fixedly connected to the rear side of the cover plate, and the back plate is fixedly connected to the steel wire rope.

[0007] As a preferred embodiment of this utility model, the surface of the well casing and the bottom surface of the cover plate are provided with rolling grooves, and a number of rolling balls are rolled inside the rolling grooves, and the rolling balls are arranged in a ring array along the axis of the well casing.

[0008] In a preferred embodiment of this invention, a connecting ring is fixedly connected to the bottom of the cover plate. The connecting ring is located inside the annular plate and is slidably connected to it. An anti-detachment plate is fixedly connected to the bottom end of the connecting ring. The top surface of the anti-detachment plate is in contact with the bottom surface of the annular plate, and the diameter of the anti-detachment plate is larger than the inner diameter of the annular plate.

[0009] In a preferred embodiment of this utility model, both ends of the inner side of the connecting plate are fixedly connected to sliding columns, the second springs are all sleeved on the surface of the sliding columns, the moving plates are all sleeved on the surface of the sliding columns and slidably connected to them, and the wire rope is located inside the sliding columns.

[0010] As a preferred embodiment of this utility model, a pulley frame is fixedly connected to the back of the rear connecting plate, and a pulley is rotatably connected to the inner side of the pulley frame via a pin. The wire rope is located inside the pulley and is tumbledly connected to it.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, through the setting of the first and second ports, allows for pumping water when the lever is moved upward, causing the slide plate to rise and compress the first spring. The slide plate then pulls the insert post out of the insertion hole and out of the second fixing plate. The handle can then be rotated to make the second port coincide with the first port, allowing the water pipe to be inserted into the well through the second and second ports. When not in use, the device is reset so that the second port is offset from the first port. This prevents small animals and garbage from entering the well casing and contaminating the water source, thus isolating them, facilitating user operation, and improving the practicality of the protective device.

[0013] 2. This utility model, through the setting of the second spring, allows the device to be reset after the user has pumped water. When the handle is turned, the back plate on the back side of the cover plate will drive the steel wire rope to stretch the moving plate, thereby putting the second spring in a stretched state. After the water pipe inside the second and first ports is pulled out, the second spring will contract, driving the moving plate and steel wire rope to rotate the back plate and cover plate. The cover plate will then cause the inclined surface of the insertion post to slide against the second fixed plate. The insertion post will be squeezed, causing the first spring to contract. When the insertion post coincides with the insertion hole, the insertion post will be inserted into the insertion hole and automatically fixed, avoiding the situation where animals and garbage enter and pollute the water source due to forgetting to reset, further improving the practicality of the device.

[0020] 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 protection scope of the present utility model.

[0021] like Figures 1 to 5As shown, a farmland well protection device includes a well casing 1, a connecting seat 2 fixedly connected to the bottom of the well casing 1, an annular plate 3 fixedly connected inside the well casing 1, a first opening 4 on the front side of the surface of the annular plate 3, a cover plate 5 attached to the top of the well casing 1, a second opening 6 on the left side of the surface of the cover plate 5, a handle 7 fixedly connected to the rear side of the surface of the cover plate 5, a first fixing plate 8 fixedly connected to the left side of the cover plate 5, a locking cylinder 9 fixedly connected to the bottom of the first fixing plate 8, and a first spring 10 fixedly connected to the bottom of the first fixing plate 8. Inside the locking cylinder 9, a sliding plate 11 is fixedly connected to the bottom of the first spring 10. The sliding plate 11 is slidably connected to the locking cylinder 9. A plug 12 is fixedly connected to the bottom of the sliding plate 11. The rear side of the plug 12 is set as an inclined surface. A second fixing plate 13 is fixedly connected to the left side of the well casing 1. An insertion hole 14 is opened on the surface of the second fixing plate 13. The bottom end of the plug 12 is located inside the insertion hole 14 and is slidably connected to it. A groove 15 is opened on the left side of the locking cylinder 9. A lever 16 is fixedly connected to the left side of the sliding plate 11. The groove 15 is located inside the lever 16 and is slidably connected to it.

[0022] refer to Figure 1 and Figure 3 Both ends of the right side of the well casing 1 are fixedly connected to a connecting plate 17. Both ends of the back of the front connecting plate 17 are fixedly connected to a second spring 18. The rear end of the second spring 18 is fixedly connected to a moving plate 19. The front of the rear connecting plate 17 has a rope hole 20. The back of the moving plate 19 is fixedly connected to a wire rope 21. The wire rope 21 extends through the rope hole 20 to the back of the well casing 1. The back plate 22 is fixedly connected to the rear side of the cover plate 5. The back plate 22 is fixedly connected to the wire rope 21.

[0023] As a technical optimization of this utility model, by setting the second spring 18, when the user forgets to reset the device after pumping water, the back plate 22 on the back side of the cover plate 5 will drive the steel wire rope 21 to stretch the moving plate 19 when the handle 7 is turned, thereby putting the second spring 18 in a stretched state. After the water pipe inside the second port 6 and the first port 4 is pulled out, the second spring 18 will contract, driving the moving plate 19 and the steel wire rope 21 to rotate the back plate 22 and the cover plate 5. The cover plate 5 will then drive the inclined surface of the insertion post 12 to slide against the second fixed plate 13. The insertion post 12 will be squeezed, causing the first spring 10 to contract. When the insertion post 12 coincides with the insertion hole 14, the insertion post 12 will be inserted into the insertion hole 14 and automatically fixed, avoiding the situation where animals and garbage enter and pollute the water source due to forgetting to reset, further improving the practicality of the device. The rear side of the top of the second fixed plate 13 is fixedly connected to a limit block, which prevents the insertion post 12 from sliding too fast and misaligning with the insertion hole 14.

[0024] refer to Figure 5The surface of the well casing 1 and the bottom surface of the cover plate 5 are both provided with grooves 23. Several balls 24 are rolled inside the grooves 23, and the balls 24 are arranged in a ring array along the axis of the well casing 1.

[0025] As a technical optimization of this utility model, the friction between the well casing 1 and the cover plate 5 is greatly reduced by the setting of the ball bearing 24, making the cover plate 5 easier and smoother when automatically resetting, and also more labor-saving when manually rotating the cover plate 5 by the throttle 7.

[0026] refer to Figure 2 A connecting ring 25 is fixedly connected to the bottom of the cover plate 5. The connecting ring 25 is located inside the annular plate 3 and is slidably connected to it. An anti-detachment plate 26 is fixedly connected to the bottom end of the connecting ring 25. The top surface of the anti-detachment plate 26 is in contact with the bottom surface of the annular plate 3. The diameter of the anti-detachment plate 26 is larger than the inner diameter of the annular plate 3.

[0027] As a technical optimization of this utility model, the cover plate 5 is limited by the setting of the anti-detachment plate 26, which avoids the problem of the cover plate 5 separating from the well casing 1 and causing misalignment and failure.

[0028] refer to Figure 1 and Figure 3 Both ends of the inner side of the connecting plate 17 are fixedly connected to the sliding column 27. The second spring 18 is sleeved on the surface of the sliding column 27. The moving plate 19 is sleeved on the surface of the sliding column 27 and slidably connected to it. The wire rope 21 is located inside the sliding column 27.

[0029] As a technical optimization of this utility model, the sliding column 27 is used to limit the second spring 18, thereby preventing bending and deformation of the second spring 18, which would affect the service life of the second spring 18.

[0030] refer to Figure 1 and Figure 3 A pulley frame 28 is fixedly connected to the back of the rear connecting plate 17. A pulley 29 is rotatably connected to the inner side of the pulley frame 28 via a pin. The wire rope 21 is located inside the pulley 29 and is tumbledly connected to it.

[0031] As a technical optimization of this utility model, the pulley 29 makes it easier to pull the wire rope 21, while avoiding frequent friction between the wire rope 21 and the rope hole 20, which would cause severe wear of the wire rope 21 and greatly affect its service life.

[0032] The working principle and usage process of this utility model are as follows: In use, the user moves the lever 16 upwards, causing the slide plate 11 to rise and compress the first spring 10. The slide plate 11 then causes the insertion post 12 to disengage from the insertion hole 14 and be pulled out of the second fixing plate 13. The handle 7 can then be rotated to align the second port 6 with the first port 4, allowing the water pipe to be inserted into the well through the first port 4 and the second port 6 for pumping. After pumping is complete, the water pipe is pulled out from the second port 6 and the first port 4. When the handle 7 is rotated, the back plate on the rear side of the cover plate 5... 22 will drive the steel wire rope 21 to stretch the moving plate 19, thereby putting the second spring 18 in a stretched state. After the water pipe inside the second port 6 and the first port 4 is pulled out, the second spring 18 will contract, driving the moving plate 19 and the steel wire rope 21 to rotate the back plate 22 and the cover plate 5. The cover plate 5 will then drive the inclined surface of the insertion post 12 to slide against the second fixed plate 13. The insertion post 12 will be squeezed, causing the first spring 10 to contract. When the insertion post 12 coincides with the insertion hole 14, the insertion post 12 will be inserted into the insertion hole 14 and automatically fixed, so that the first port 4 is in a closed state.
