Description

Technical Field

[0001] The utility model relates to the technical field of valve control equipment, in particular to a valve control module. Background Art

[0002] In agricultural production, the requirement for precise control of irrigation is getting higher and higher. Therefore, more and more solenoid valves are used for the valves involved in irrigation, which makes it gradually convenient to control multiple valves through a valve control circuit board. The valve control module equipped with the valve control circuit board is usually arranged at a position close to the valve in the field. After receiving a wired or wireless remote instruction, it controls the solenoid valve.

[0003] The existing valve control circuit board is usually arranged in a housing composed of two outer shells and fixed by multiple groups of screws and nuts, and then the whole is installed on the installation rod in the field. However, this makes the existing valve control module have some problems: sometimes it is necessary to replace the battery of the valve control module, and sometimes it is necessary to connect the valve control module to different valves when restoring the fertility of the plot during crop rotation. Each time it is troublesome to open the outer shell; in order to achieve a better rainproof effect, the outer shell is usually fully enclosed after assembly, which makes the valve control circuit board unable to ventilate and dissipate heat well and is easily damaged in hot weather. Summary of the Utility Model

[0004] In view of the above defects, the utility model provides a valve control module, which is easy to install and maintain, and can achieve better heat dissipation while being waterproof.

[0005] In order to achieve the purpose of the utility model, the following technology is proposed:

[0006] A valve control module includes:

[0007] A base, including a placement frame with through holes on both sides. An installation plate is arranged in the placement frame. A battery compartment is fixed on the other side of the installation plate. A pair of convex blocks parallel to the through direction of the opening of the placement frame are arranged at the upper end of the placement frame, and a rain guide groove is arranged at the upper end of the convex blocks;

[0008] A control board, assembled on one side of the installation plate, and the control board includes a valve control interface for connecting a solenoid valve;

[0009] A pair of outer cover assemblies, respectively assembled at both ends of the base. The outer cover assembly includes a cover body with openings on one side and the bottom surface. A magnet extending outside one side of the cover body is arranged on the inner top surface of the cover body. The magnetic poles of the two magnets of the two outer cover assemblies are opposite, and the magnets are used to slide through between the two convex blocks and be magnetically fixed.

[0010] Furthermore, a plurality of installation holes are formed on one side surface of the installation plate. By screwing the positioning holes and the installation holes of the control board, the control board is fixed.

[0011] Further, there is a predetermined distance between the lower end of the mounting plate and the inner bottom wall of the placement frame. The battery compartment includes an output port, and the control board further includes a battery interface. The wire connected to the battery interface is connected to the output port of the battery compartment through the gap between the lower end of the mounting plate and the inner bottom wall of the placement frame.

[0012] Further, arc-shaped side guide grooves extending downward are respectively connected to both ends of the rain guide groove.

[0013] Further, a bottom block is provided at the lower end of the placement frame, and a screw hole is provided on the lower end surface of the bottom block for fixing the entire valve control module.

[0014] Further, when the two magnetic blocks are fixed, their contact surfaces are located below the rain guide groove.

[0015] Further, an n-shaped sealing strip is also provided on one side of the cover body. When the two magnetic blocks are in contact and fixed, the lateral sides of the horizontal parts of the two n-shaped sealing strips of the two outer cover assemblies are respectively closely attached to both sides of the rain guide groove.

[0016] Further, a horizontal dust-proof plate is also provided inside the cover body, and a wire opening through which the wire led out from the valve control interface passes is provided on one horizontal dust-proof plate.

[0017] The beneficial effects of this technical solution are as follows:

[0018] 1. The two outer cover assemblies are fixed on both sides of the base by magnetic attraction. When replacing the battery or connecting different solenoid valves, the outer cover assemblies can be directly and conveniently pulled apart for maintenance operations without complex disassembly work.

[0019] 2. The rain guide groove covers the connection part of the two magnetic blocks, which can divert rainwater. The outer cover assemblies also cover both ends of the base, and it is not easy for rainwater to leak in. The opening between the lower end of the outer cover assembly and the base cannot cause rainwater to flow back, and ventilation can be achieved to reduce the temperature inside the base.

A pair of convex blocks 15 parallel to the penetration direction of the opening of the placement frame 11 are provided at the upper end of the placement frame 11. A rain guide groove 16 is provided at the upper end of the convex block 15. Both ends of the rain guide groove 16 are respectively connected with side guide grooves 17 that extend downward in an arc shape. A bottom block 18 is provided at the lower end of the placement frame 11. A screw hole 19 is formed on the lower end surface of the bottom block 18 for fixing on a base in the field having an upward protruding screw rod to fix the entire valve control module.

A magnet 32 extending outside one side of the cover body 31 is provided on the inner top surface of the cover body 31. The magnetic poles of the two magnets 32 of the two outer cover assemblies 3 are opposite. The magnet 32 is used to slide through between the two bumps 15 and be magnetically fixed. When the two magnets 32 are fixed, their contact surfaces are located below the rainwater guiding groove 16 to prevent rainwater from entering the gaps at the contact surfaces. An n-shaped sealing strip 33 is also provided on one side of the cover body 31. When the two magnets 32 are in contact and fixed, the lateral sides of the horizontal parts of the two n-shaped sealing strips 33 of the two outer cover assemblies 3 are respectively closely attached to both sides of the rainwater guiding groove 16. A horizontal dust-proof plate 34 is also provided inside the cover body 31 to prevent dust from being blown into the base 1 in windy weather. One end surface of the horizontal dust-proof plate 34 contacts the lower side surface of the opening side of the mounting plate 12. A wire opening through which the wire led out from the valve control interface 21 passes is also provided on the horizontal dust-proof plate 34 close to the control board 2 side.
