Description

Technical Field

[0001] The utility model relates to the technical field of agricultural irrigation equipment and its peripheral supporting facilities, in particular to a valve control device and an agricultural irrigation system. Background Art

[0002] Most irrigation valves use customized parts, and there are no standard parts specifically for use, which leads to an increase in production costs. When designing the valve, we first select standard parts, and then design the valve according to the dimensions of the standard parts. When purchasing parts, only relatively cheap standard parts need to be purchased, which reduces the expenditure on manufacturing costs to a certain extent.

[0003] When connecting the electric push rod and the valve handle, most irrigation valves use customized connectors for connection, which not only increases the cost, but also makes the valve assembly cumbersome, bringing a certain amount of workload to the assembly. And due to the non-fixed connection position of the connectors, the connection is not accurate enough, resulting in the valve switch not being able to be fully opened or fully closed, affecting the working reliability of the valve.

[0004] In the prior art, the automation of the valve is mainly realized by a rotating motor, which requires a larger power and torque of the motor, resulting in a reduction in the battery life of the electric valve. The problem of valve closing in case of an emergency is not considered. The manual closing steps of most valves are complex. For example, for a valve with a rotating motor, pliers or a wrench have to be used for manual handling. The valves of some products are customized by the manufacturer. If the valve breaks down, it needs to be purchased from the manufacturer. The valve control structure in the prior art is relatively complex, using more connectors, making the manual installation more complex and increasing the possibility of problems.

[0031] The purpose of the present utility model is to provide a valve control device and an agricultural irrigation system to solve the problems existing in the above-mentioned prior art, simplify the structure of the valve control device, reduce the space occupied by the device, and save the use cost.

[0032] To make the above objects, features and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0033] Embodiment 1

[0034] This embodiment provides a valve control device, including a tee 10, a support mechanism and an actuating mechanism. Please refer to Figures 1 - 5, the tee 10 includes a middle opening and two end openings located at both ends of the middle opening. Pipe orifice valves 1 are provided at both end openings. The support mechanism is located between the two pipe orifice valves 1. The support mechanism includes a riding bracket 3 and a clamp 9. The riding bracket 3 is detachably connected to the clamp 9. The riding bracket 3 and the clamp 9 cooperate to clamp the tee 10 tightly. The actuating mechanism includes a solar panel 8 and an electric push rod 2. The solar panel 8 is fixed on the riding bracket 3. The solar panel 8 is also connected with a storage battery. Both the solar panel 8 and the storage battery are electrically connected to the electric push rod 2. The fixed end of the electric push rod 2 is rotatably hinged to the fixed rod 4 of the riding bracket 3 to achieve rotation. The movable end of the electric push rod 2 is hinged to the handle of the pipe orifice valve 1. The reciprocating sliding of the movable end of the electric push rod 2 can drive the handle to rotate to control the opening and closing of the pipe orifice valve 1. The electric push rod 2 corresponds to the pipe orifice valve 1 one by one.

[0035] For the valve control device of the present utility model, the support mechanism uses the riding bracket 3 and the clamp 9 to cooperate to clamp the tee 10 tightly. The connection structure is simple and the operation is convenient, which is beneficial to reducing the occupied space of the device and providing stable support for the actuating mechanism at the same time. The actuating mechanism uses the electric push rod 2 to drive the handle to rotate to achieve the opening and closing of the pipe orifice valve 1. The movable end of the electric push rod 2 is hinged to the handle, and the hinge is directly realized by opening a hole in the handle. The connection position is accurate, avoiding the situation that the pipe orifice valve 1 cannot be fully opened or fully closed. The solar panel 8 and the storage battery provide a power source for the electric push rod 2, saving energy. The solar panel 8 is connected with a storage battery to store the excess electric energy. In the case of no sunlight irradiation, the storage battery provides electric energy for the electric push rod 2 to ensure the endurance of the valve control device and improve the working reliability of the device. It should also be noted that the support mechanism adopts the riding bracket 3, which avoids affecting the setting direction of the middle opening of the tee 10 while ensuring the stability of the device, enabling the middle opening of the tee 10 to be connected to the pipes below and on the left and right sides, improving the flexible adaptability of the valve control device.

[0036] It should be explained here that the fixed end of the electric push rod 2 is the shell end, and the movable end is the push rod end. The structural composition of the electric push rod 2 is common knowledge for those skilled in the art and will not be elaborated here. The storage battery can be a lithium battery or other types of storage batteries, and the storage battery can be arranged on the riding bracket 3 to ensure the structural stability of the device.

[0037] Among them, the riding bracket 3 includes an installation plane and bracket side walls connected to the installation plane. The number of bracket side walls is four groups. The bracket side walls are perpendicular to the installation plane and are in an arched structure to accommodate the tee 10 and other pipes connected to the middle opening of the tee 10, avoiding affecting the connection between the tee 10 and other pipes. The middle opening of the tee 10 can be opened downward, left, or right, facilitating the connection between the tee 10 and other pipes. While reducing the space occupied by the support mechanism, the adaptability of the tee 10 is improved. The solar panel 8 is arranged on the installation plane, and the clamp 9 is bolted to the bracket side wall, with stable connection and convenient disassembly and assembly.

[0038] Specifically, one end of the fixed rod 4 is fixedly connected to the riding bracket 3, and the other end of the fixed rod 4 extends out of the riding bracket 3 and is hinged to the fixed end of the electric push rod 2. The fixed rods 4 and the electric push rods 2 are in one-to-one correspondence. The fixed end of the electric push rod 2 is hinged to the riding bracket 3 by means of the fixed rod 4. The end of the fixed rod 4 hinged to the electric push rod 2 extends out of the riding bracket 3, providing sufficient movement space for the electric push rod 2 and forming a linkage mechanism at the same time, further improving the movement accuracy of the electric push rod 2 driving the handle to rotate and enhancing the opening and closing reliability of the pipe orifice valve 1.

[0039] In this specific embodiment, the fixed rod 4 is made of a square pipe. The fixed rod 4 is bolted to the riding bracket 3 and the number of bolts is at least two groups, ensuring the connection stability between the fixed rod 4 and the riding bracket 3, avoiding the sliding or rotation of the fixed rod 4 from affecting the action accuracy of the electric push rod 2, reducing the tiny displacement generated by the electric push rod 2 during operation, being beneficial to reducing the error of the electric push rod 2, and thus being able to more accurately control the opening and closing degree of the pipe orifice valve 1 under the action of the electric push rod 2.

[0040] It should also be noted that the two groups of electric push rods 2 and the fixed rods 4 are symmetrically arranged with the axis of the tee 10 as the axis of symmetry, improving the force uniformity of the tee 10.

[0041] More specifically, the support mechanism further includes a base 5 and a vertical rod 6. The base 5 is fixed on the riding bracket 3, one end of the vertical rod 6 is connected to the base 5, and the other end of the vertical rod 6 is connected to the solar panel 8. The support mechanism uses the base 5 and the vertical rod 6 to fix and support the solar panel 8, improving the structural stability of the solar panel 8, enabling it to have a certain ability to resist bad weather, and at the same time keeping the solar panel 8 at a certain height, thereby ensuring that sunlight can shine on the solar panel 8 and ensuring that the solar panel 8 can supply power to the electric push rod 2. Moreover, the solar panel 8 stores electrical energy using a storage battery. In weather without sunlight, the storage battery is used to supply power to the electric push rod 2, ensuring that the electric push rod 2 can work smoothly and improving the working reliability of the device. In other specific implementation manners achievable by the present utility model, the vertical rod 6 is a standard C-shaped steel member, and its length can be adjusted according to the height of the crops to ensure that sunlight can shine on the solar panel 8. The connection position between the vertical rod 6 and the base 5 can also be adjusted, thereby achieving the purpose of adjusting the height of the solar panel 8 and further improving the flexible adaptability of the solar panel 8.

[0042] Among them, the base 5 is bolted to the riding bracket 3, with firm connection and convenient disassembly and assembly. Moreover, the base 5 has an installation groove adapted to the vertical rod 6, and one end of the vertical rod 6 is fixed in the installation groove, further improving the structural stability of the vertical rod 6 and the solar panel 8. The other end of the vertical rod 6 is connected to the solar panel 8. In actual application, the vertical rod 6 and the solar panel 8 are set to be rotatably connected, and a locking element is provided between them. In actual application, the angle of the solar panel 8 can be adjusted according to the installation position of the device, and after adjustment, it is fixed using the locking element, further improving the flexible adaptability of the solar panel 8 and ensuring that it can provide a stable power source for the electric push rod 2.

[0043] Furthermore, the movable end of the electric push rod 2 is hinged to the handle using a pin shaft 11 to achieve rotation. The axis of the pin shaft 11 is parallel to the rotation axis of the handle, using the pin shaft 11 to improve the relative rotation smoothness between the movable end of the electric push rod 2 and the handle, and then ensuring that the handle can rotate smoothly to achieve the opening and closing operation of the pipe orifice valve 1. In actual application, the movable end of the electric push rod serves as a connecting member between the pipe orifice valve 1 and the electric push rod 2, playing a role in force transmission. Under the accurate control of the valve controller 7, the pipe orifice valve 1 can be fully opened or closed. The electric push rod 2 can accurately control the stroke of its movable end, avoiding the phenomenon of damage to the pipe orifice valve 1 caused by excessive manual force, and can save a great deal of manpower under the replacement of the electric push rod 2.

[0044] It should also be noted here that the support mechanism and the action mechanism of the present utility model mostly adopt detachable connection methods such as hinge connection and bolt connection, avoiding fixed connection methods such as welding, greatly facilitating the later maintenance of the device. Only damaged parts can be replaced, saving maintenance costs.

[0045] Furthermore, the action mechanism further includes a valve controller 7. The electric push rod 2 is communicatively connected to the valve controller 7, and the valve controller 7 is arranged on the riding bracket 3. The valve controller 7 is used to control the action of the electric push rod 2, thereby controlling the opening and closing of the pipe orifice valve 1, further improving the controllability of the device, facilitating the operator to monitor the working state of the device in a timely manner, and providing convenience for the smooth operation of the agricultural irrigation system. The solar panel 8 and the storage battery are also electrically connected to the valve controller 7. The solar panel 8 and the storage battery provide power sources for the electric push rod 2, the valve controller 7 and other electrical components, ensuring the stable operation of the device. The solar energy absorbed by the solar panel 8 is converted into electrical energy to provide electrical energy for the electric push rod 2 and the valve controller 7, greatly saving the use of electricity, and at the same time avoiding the danger of high-voltage operation. The electrical energy obtained by the solar panel 8 and the electrical energy stored in the storage battery provide electrical energy for the electric push rod 2, and at the same time are sufficient to enable the valve controller 7 to have sufficient electrical energy to control the electric push rod 2 to work.

[0046] Embodiment 2

[0047] This embodiment provides an agricultural irrigation system, including the valve control device of Embodiment 1, and uses the valve control device to control the opening and closing of each valve in the agricultural irrigation system, improving the operation reliability of the system.

[0048] In practical applications, the pipelines in the agricultural irrigation system may have a working condition with multiple passages. Multiple groups of the valve control devices of Embodiment 1 can be set according to control needs. For example, for a five-way passage, as Figure 6 shown, two three-way pipes 10 are connected to form a five-way pipeline, which is convenient to connect and assemble, so as to meet the different pipeline connection requirements of the system. In actual production, it can be flexibly assembled according to specific irrigation requirements to realize the construction of different types of passages and improve the flexible adaptability of the system.

The descriptions of the above embodiments are only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
