Description

Technical Field

[0001] The utility model belongs to the technical field of irrigation electric valves, and more specifically, relates to a protection structure for an irrigation electric valve. Background Art

[0002] Irrigation electric valves play an important role in agricultural irrigation systems. They control the opening and closing of valves through motor drive to achieve automated irrigation control. The irrigation electric valve controls the opening and closing of the valve through the forward and reverse rotation of the motor.

[0003] The desert environment is extreme and water resources are extremely scarce. However, flood irrigation, as an effective water resource utilization method, can provide moisture for local forest and grass vegetation, alleviate the problem of water shortage and degradation, and achieve ecological restoration. Therefore, irrigation electric valves can be used in the desert environment. However, in the desert environment, the large temperature difference between day and night is likely to cause damage to the irrigation electric valve, and the service life of the irrigation electric valve is likely to be reduced.

[0004] To solve the above problems, a protection structure for an irrigation electric valve is proposed in this application. Summary of the Utility Model

[0005] In view of the problems in the related art, the utility model proposes a protection structure for an irrigation electric valve to overcome the above technical problems existing in the prior related art.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A protection structure for an irrigation electric valve includes a base. The top of the base is fixedly connected with an electric valve body. A load-bearing rod is welded to the top of the base. An annular water tank is fixedly sleeved on the outer surface of the electric valve body. The bottom of the annular water tank is fixedly connected with the top of the load-bearing rod. A heating wire is installed on the inner surface of the annular water tank. Heat dissipation fins are installed at the bottom of the annular water tank. A supply pipe is fixedly inserted into the top cavity of the annular water tank. A protection groove is opened at the top of the base.

[0008] A dust-proof plug is movably inserted into the inner surface of the supply pipe. A handle is fixedly connected to the top of the dust-proof plug. By setting the dust-proof plug and the handle, the operator can hold the handle to control the movement of the dust-proof plug, and the handle inserted into the supply pipe can minimize the pollution of the supply pipe by external impurities.

[0009] An adjusting rod is lapped on the top of the annular water tank. A sunshade is rotatably connected to the top of the adjusting rod. By setting the adjusting rod and the sunshade, the sunshade is located directly above the electric valve body, and the sunshade can minimize the temperature rise of the electric valve body caused by direct sunlight, and avoid the reduction of work efficiency caused by the continuous temperature rise of the electric valve body.

[0010] A threaded rod is welded to the top of the annular water tank, and the adjusting rod is threadedly connected to the outer surface of the threaded rod. By providing the threaded rod, the adjusting rod can drive the sunscreen cover to move up and down along the outer surface of the threaded rod, facilitating the rapid adjustment of the shielding angle and shading range of the sunscreen cover.

[0011] A rotating shaft is rotatably connected to the inner surface of the base. A protective cloth is wound around the outer surface of the rotating shaft. A hook is installed on the outer surface of the protective cloth. A positioning block is fixedly connected to the outer surface of the annular water tank. The outer surface of the hook is movably connected to the inner surface of the positioning block. By providing the rotating shaft, the protective cloth, the hook and the positioning block, the operator can hold the hook and move it upward to gradually release the protective cloth on the surface of the rotating shaft. When the hook catches the positioning block on the surface of the annular water tank, the released protective cloth can provide protection for the outer surface of the electric valve body, minimizing the contact area between the electric valve body and the dust and sand, and avoiding dust and sand from entering the electric valve body and affecting its normal operation as much as possible.

[0012] A connecting rod is movably inserted into the inner cavity of the base. The outer surface of the connecting rod is welded to the outer surface of the rotating shaft. A handle is fixedly connected to the side of the connecting rod away from the base. A limiting nut is threadedly connected to the outer surface of the connecting rod. By providing the connecting rod, the handle and the limiting nut, the operator can rotate the handle to quickly wind up the protective cloth through the connecting rod and the rotating shaft. And after the limiting nut on the surface of the connecting rod rotates and moves under force and is in close contact with the outer surface of the base, the rotation of the connecting rod is restricted, facilitating the quick storage of the protective cloth and improving the space utilization rate.

[0013] In summary, the technical effects and advantages of the present utility model are as follows:

[0014] 1. For the irrigation electric valve protection structure, the operator can pour water into the annular water tank through the supply pipe. The annular water tank wraps around the outside of the electric valve body to form a protective layer, which helps to reduce the direct heat exchange between the electric valve body and the external environment. At the same time, the heat dissipation fins at the bottom of the annular water tank can also improve the overall heat dissipation efficiency of the annular water tank and the electric valve body. Then, by starting the heating wire inside the annular water tank, the water temperature inside the annular water tank can be flexibly adjusted, minimizing the adverse effects of large day-night temperature differences on the electric valve body and extending the service life of the electric valve body as much as possible.

[0015] 2. For the irrigation electric valve protection structure, by rotating the limiting nut away from the base, the rotation restrictions of the connecting rod and the rotating shaft can be quickly released. Then, by moving the hook upward, the protective cloth on the surface of the rotating shaft can be gradually released. And after the hook catches the positioning block under force, the stretched protective cloth can play a role in protecting the electric valve body, minimizing the contact area between the electric valve body and the dust and sand and reducing the damage of the dust and sand to the electric valve body as much as possible.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Refer to Figure 1-3, An irrigation electric valve protection structure, including a base 1. A top of the base 1 is fixedly connected with an electric valve body 2, and the electric valve body 2 is installed at a central part of the top of the base 1; A load-bearing rod 3 is welded on the top of the base 1. An outer surface of the electric valve body 2 is fixedly sleeved with an annular water tank 4, and a bottom of the annular water tank 4 is fixedly connected with a top of the load-bearing rod 3. The load-bearing rod 3 can provide additional supporting force for the annular water tank 4; A heating wire 5 is installed on an inner surface of the annular water tank 4. The heating wire 5 uses an external power supply, and after the heating wire 5 is started, it can increase the temperature inside the annular water tank 4. A heat sink 6 is installed at a bottom of the annular water tank 4. The heat sink 6 contacting with air can accelerate the heat dissipation efficiency of the annular water tank 4; A supply pipe 7 is fixedly inserted into a top cavity of the annular water tank 4. An operator can pour pure water source into the annular water tank 4 through the supply pipe 7. Then the annular water tank 4 wraps around the outside of the electric valve body 2 to form a protective layer, which helps to reduce the direct heat exchange between the electric valve body 2 and the external environment, and the water source in the annular water tank 4 can minimize the interference of the external temperature on the electric valve body 2; A protective groove 8 is opened on the top of the base 1.

[0026] Referring to Figure 2 and Figure 4 , A dust-proof plug 9 is movably inserted into an inner surface of the supply pipe 7. An outer surface of the dust-proof plug 9 is movably connected with the inner surface of the supply pipe 7. When the dust-proof plug 9 is inserted into the supply pipe 7 under force, it can avoid the pollution of the supply pipe 7 and the annular water tank 4 by external impurities as much as possible; A handle 10 is fixedly connected to a top of the dust-proof plug 9. The handle 10 is installed at a central part of the top of the dust-proof plug 9, and an operator can control the movement of the dust-proof plug 9 more labor-savingly by holding the handle 10.

[0027] Referring to Figure 1 , Figure 2 and Figure 5 , An adjusting rod 11 is lapped on a top of the annular water tank 4. A top of the adjusting rod 11 is rotatably connected with a sunshade 12, and the sunshade 12 is located directly above the electric valve body 2; The adjusting rod 11 can provide supporting force for the sunshade 12. The semi-circular sunshade 12 can avoid the temperature rise of the electric valve body 2 caused by direct sunlight as much as possible, and the sunshade 12 can play a role in protecting the electric valve body 2. A threaded rod 13 is welded on the top of the annular water tank 4. The adjusting rod 11 is threadedly connected to an outer surface of the threaded rod 13. When the adjusting rod 11 is rotated under force, it slides up and down along the surface of the threaded rod 13. Furthermore, the working height of the sunshade 12 can be adjusted and controlled by rotating the adjusting rod 11, which is convenient for quickly adjusting the shielding range and height of the sunshade 12.

[0028] Referring to Figure 1 and Figure 6, a rotating shaft 14 is rotatably connected to the inner surface of the base 1. The rotating shaft 14 is located in the protective groove 8. A protective cloth 15 is wound around the outer surface of the rotating shaft 14. The length of the protective cloth 15 is less than the length of the rotating shaft 14. A hook 16 is installed on the outer surface of the protective cloth 15. A positioning block 17 is fixedly connected to the outer surface of the annular water tank 4. The outer surface of the hook 16 is movably connected to the inner surface of the positioning block 17. When the operator moves the hook 16 upward, the protective cloth 15 can be driven to move in the same direction. Then the rotating shaft 14 is stressed and rotates to gradually release the protective cloth 15. When the hook 16 hooks the positioning block 17 on the surface of the annular water tank 4, the unfolded protective cloth 15 can minimize the contact between the electric valve body 2 and the dust, and avoid the brake constantly contacting the electric valve body 2 and causing damage.

[0029] Referring to Figure 1 and Figure 6 , a connecting rod 18 is movably inserted into the inner cavity of the base 1. The outer surface of the connecting rod 18 is welded to the outer surface of the rotating shaft 14. A handle 19 is fixedly connected to the side of the connecting rod 18 away from the base 1. When the operator rotates the handle 19, the rotating shaft 14 can be driven to rotate through the connecting rod 18, and the rotation of the rotating shaft 14 can wind up the protective cloth 15, which is convenient for quickly storing the protective cloth 15 and avoiding damage caused by the random placement of the protective cloth 15 as much as possible. A limit nut 20 is threadedly connected to the outer surface of the connecting rod 18. The limit nut 20 can slide along the surface of the connecting rod 18 when it is stressed and rotated. When the limit nut 20 is stressed and moves toward the base 1 and tightly abuts against the surface of the base 1, the rotation of the connecting rod 18 and the rotating shaft 14 is restricted, and the connecting rod 18 is prevented from rotating accidentally due to external interference as much as possible.

[0030] Working principle: First, the temperature difference between day and night in the desert environment is relatively large. The electric valve body 2 is prone to damage when working in an environment with a large temperature difference between day and night. The operator can pour water into the annular water tank 4 through the supply pipe 7. The annular water tank 4 wraps around the outside of the electric valve body 2 to form a protective layer, which helps to reduce the direct heat exchange between the electric valve body 2 and the external environment. The annular water tank 4 and the heating wire 5 together form a heat preservation system to maintain the temperature stability of the electric valve body 2 and its surrounding environment by reducing heat exchange and providing heat. When the external temperature is relatively high, the heat dissipation fins 6 at the bottom of the annular water tank 4 can also improve the overall heat dissipation efficiency of the annular water tank 4 and the electric valve body 2. When the external temperature is relatively low, the water temperature inside the annular water tank 4 can be flexibly adjusted by starting the heating wire 5 inside the annular water tank 4, minimizing the adverse effects of the large temperature difference between day and night on the electric valve body 2 and extending the service life of the electric valve body 2 as much as possible.

[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
