Description

Technical Field

[0001] The utility model relates to the technical field of integrated controller protection, in particular to a protective cover for a water pump integrated controller. Background Technique

[0002] A water pump integrated controller is an intelligent control device that integrates functions such as starting, stopping, protecting, and monitoring of a water pump. It is widely used in various water pump systems. The water pump integrated controller is usually installed in an electrical box near the water pump and is connected to the water pump motor. It realizes remote or on-site control of the water pump through sensors and communication modules. For example, a sewage treatment intelligent integrated controller with the publication number CN215188086U includes a C-shaped plate. Both ends inside the C-shaped plate are provided with first chutes, and sliders are slidably installed inside the first chutes. A circuit board is slidably installed between the two sliders.

[0003] Although the utility model forms a box body through the cooperation of the C-shaped plate, the slider, and the control board, it can ensure the safety protection of the circuit board. And through the sliding connection between the first chute at both ends of the C-shaped plate and the slider, and then in cooperation with the fixing mechanism composed of a sleeve, a limiting ring, a spring, a positioning rod, a plug rod, a limiting disk, a limiting groove, and a positioning hole, the assembly and disassembly of the box body are more convenient. The setting of the cooling mechanism composed of the circulating water pipe and the water pump at the bottom of the circuit board replaces the traditional fan cooling method, not only ensuring the heat dissipation effect of the device, but also effectively preventing dust from entering and ensuring the service life of the device.

[0004] However, in the specific use process, the water source inside the circulating water pipe is pumped by the water pump, and the water source is controlled to circulate inside and outside the slider to accelerate the heat dissipation inside the box body, so that the working state of the water pump cannot be adjusted according to the temperature inside the box body. As a result, the water pump needs to continuously work to achieve the cooling of the box body, thereby increasing the power resource consumption and causing inconvenience in use. In view of this, we propose a protective cover for a water pump integrated controller. Content of the Utility Model

[0032] The protective cover of the water pump integrated controller comprises a protective cover 1 and a box body 2 which is movably inserted in the protective cover 1 and used to place the water pump integrated controller. The side wall of the protective cover 1 is located above the box body 2 and is rotatably connected to a limit block through a positioning shaft. When the limit block is rotated to be perpendicular to the top of the box body 2, the side of the limit block close to the protective cover 1 contacts the outer wall of the box body 2, thereby limiting the position of the box body 2. The outer wall of the limit block is coated with a damping rubber layer, which is used to increase the friction resistance of the limit block during rotation, so as to avoid the limit block swinging autonomously and affecting its stability under non-manual operation;

[0033] A cavity is provided between the inner wall and the outer wall of the side of the protective cover 1, and a semiconductor cooling sheet 3 is provided in the cavity so as to cool the inside of the cavity through the semiconductor cooling sheet 3.

[0034] The inner wall of the protective cover 1 is provided with a plurality of air holes 11 communicating with the inside of the cavity, so that the cold air in the cavity can enter the protective cover 1 through the air holes 11, the inner wall at the top of the protective cover 1 is provided with a temperature and humidity sensor 13, the top of the protective cover 1 is provided with a controller 14, the top of the protective cover 1 is movably connected with a drying box 5 for loading desiccant particles, the drying box 5 and the box body 2 are both hollow structures, so that the cold air in the protective cover 1 can pass through the holes on the box body 2 and contact the water pump integrated controller placed therein to achieve cooling, while the moisture in the gas in the protective cover 1 can enter the interior through the holes on the drying box 5 and fully contact the desiccant particles to achieve dehumidification;

[0035] As a preferred embodiment of the present invention, the bottom end of the drying box 5 passes through the top outer wall of the protective cover 1 and extends into the interior thereof, the bottom end of the drying box 5 is located below the top of the box body 2, and the side walls of the drying box 5 are in contact with the inner side walls of the box body 2, so that the bottom end of the drying box 5 extends into the box body 2 to limit the box body 2, thereby improving the stability of the box body 2.

[0036] As a preferred embodiment of the present invention, an upper plate is integrally formed at the top of the drying box 5, and a columnar rod 16 is vertically provided at the top of the protective cover 1 and at the corresponding corner of the upper plate. The top of the columnar rod 16 passes through the upper plate and is threadedly connected with a nut 161. A columnar groove slidably connected to the columnar rod 16 is provided at the top of the upper plate. The threaded connection between the columnar rod 16 and the nut 161 is used to detachably connect the upper plate and the protective cover 1, thereby improving the convenience of replacing the drying box 5.

[0037] As a preferred embodiment of the present invention, a clamping plate 4 for limiting the top of the water pump integrated controller is provided at the center of the protective cover 1, two quadrilateral prisms 41 are vertically provided at the top of the clamping plate 4, the top of the quadrilateral prism 41 passes through the inner wall of the top of the protective cover 1 and extends to the outside, the quadrilateral prism 41 is slidably connected to the protective cover 1, a T-shaped fixing plate 12 is provided at the top of the protective cover 1 and in the middle of the two quadrilateral prisms 41, and a threaded rod 121 and a guide rod 122 are respectively provided at the bottom end of the horizontal axis part of the fixing plate 12 and near both ends;

[0038] As a preferred embodiment of the present invention, the threaded rod 121 is threadedly connected to the corresponding quadrilateral prism 41, the threaded rod 121 is rotatably connected to the fixed plate 12, the top end of the threaded rod 121 passes through the fixed plate 12 and is provided with a handwheel, and the guide rod 122 is slidably connected to the corresponding quadrilateral prism 41 so as to guide and limit the moving trajectory of the quadrilateral prism 41 to avoid the quadrilateral prism 41 from offset during movement.

[0039] As a preferred embodiment of the present invention, an indicator light 15 is provided on the top of the protective cover 1. The indicator light 15 and the temperature and humidity sensor 13 are electrically connected to the controller 14 through wires. Specifically, when the temperature and humidity sensor 13 detects that the temperature in the protective cover 1 is higher than the value set by the controller 14, the controller 14 starts the semiconductor refrigeration sheet 3 so that the semiconductor refrigeration sheet 3 cools the inside of the cavity. When the temperature and humidity sensor 13 detects that the humidity in the protective cover 1 is higher than the value set by the controller 14, the controller 14 starts the indicator light 15 so that the indicator light 15 lights up to warn the user.

[0040] It should be added that the electronic components in the indicator light 15, temperature and humidity sensor 13, controller 14 and semiconductor refrigeration plate 3 in this embodiment are all universal standard parts or parts known to technical personnel in this field, and their structures and principles can be known to technical personnel in this field through technical manuals or through conventional experimental methods.

[0041] When the protective cover of the water pump integrated controller of the utility model is used, the water pump integrated controller is placed in the box body 2, and then the box body 2 is inserted into the protective cover 1, and then the limit block is rotated to be perpendicular to the top of the protective cover 1, so that the limit block limits the side wall of the box body 2, and then the drying box 5 is inserted into the protective cover 1, so that the columnar rod 16 passes through the columnar groove opened on the top of the upper plate and then is threadedly connected with the nut 161 to realize the detachable connection of the drying box 5;

[0042] Then, the hand wheel is turned to rotate the threaded rod 121. At this time, the quadrilateral prism 41 threadedly connected to the threaded rod 121 moves along the axial direction of the threaded rod 121 toward the side close to the box body 2. At the same time, the other quadrilateral prism 41 moves synchronously along the axial direction of the guide rod 122, thereby adjusting the height of the clamping plate 4. The clamping plate 4 continuously approaches the inner wall of the bottom end of the box body 2 until it fits with the top of the water pump integrated controller to achieve the clamping limit of the water pump integrated controller.

[0043] When the temperature and humidity sensor 13 detects that the temperature inside the protective cover 1 is higher than the value set by the controller 14, the controller 14 starts the semiconductor refrigeration plate 3, so that the semiconductor refrigeration plate 3 cools the inside of the cavity, and the cold air passes through the air vents 11 and the holes on the box body 2 and contacts the water pump integrated controller to achieve cooling. At the same time, the moisture in the gas passes through the holes on the drying box 5 and contacts the desiccant particles filled therein to achieve dehumidification, thereby achieving cooling of the water pump integrated controller while effectively reducing the impact of dust and moisture on the water pump integrated controller.
