Description

Technical Field

[0001] This utility model relates to the field of water pump controller technology, and in particular to a photovoltaic water pump controller that is easy to assemble and disassemble. Background Technology

[0002] A water pump controller starts and stops the water pump based on data such as the detected water source status, water consumption in the pipeline, and changes in pipeline pressure. It can be a traditional system consisting of a pressure tank, pressure switch, water shortage protection device, check valve, four-way valve, etc. The complete isolation of the live parts from the pipeline and the highly sealed control box give the controller a level of safety that traditional systems cannot match. Water pumps need to be moved to different locations every day during operation. Since the water pump controller has a precision structure, it needs to be disassembled and stored separately each time the water pump is moved. However, existing water pump controllers are usually fixed directly to the water pump with screws, making disassembly and assembly cumbersome.

[0003] For example, a water pump controller that is easy to install and remove is disclosed in Chinese patent literature (publication number: CN219220758U). Although this patent uses a mounting frame, miniature bearing, miniature ball screw, miniature handwheel, miniature ball screw slider, connecting rod, plug-in rod and fixed sliding sleeve, our design improvements and actual use have shown that this device has a reasonable structure and good practicality. The controller body is installed and fixed by plugging in the screw, which has good installation stability, a longer service life than spring, and makes the installation and removal of the controller body quick and convenient, which is conducive to promotion.

[0004] However, the controller is inserted into the mounting frame as a whole. If the controller and the mounting frame are inserted seamlessly, it will affect the heat dissipation of the controller and make it difficult to remove. If there is a certain gap between the controller and the mounting frame, the plug rod and the plug slot will limit the controller, but it will not prevent the controller from swaying left and right along the plug rod through the plug slot. In addition, it will generate continuous vibration when the water pump is working, which will increase the swaying amplitude and reduce the service life of the controller. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of disassembling and assembling photovoltaic water pump controllers and their susceptibility to vibrations that reduce their service life.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A photovoltaic water pump controller that is easy to assemble and disassemble includes a water pump body. A shock-absorbing mechanism is provided on the front of the water pump body, and the shock-absorbing mechanism includes a mounting plate. The back of the mounting plate is fixedly connected to the front of the water pump body.

A buffer spring is fixedly connected to the inner bottom wall of the limiting groove. One end of the buffer spring is fixedly connected to the lower end of the limiting slider.

[0009] The mounting plate is equipped with a quick-release mechanism on its front side.

[0027] Example

[0028] like Figure 1-4 As shown, this utility model provides a technical solution: a photovoltaic water pump controller that is easy to assemble and disassemble, including a water pump body 1. The front of the water pump body 1 is firmly fixed to a shock-absorbing mechanism by welding process, which protects the controller body 34 from vibration interference from the operation of the water pump and greatly extends its service life. The shock-absorbing mechanism includes a mounting plate 2. The mounting plate 2 is a key component for bearing and buffering. Its back is closely attached to the front of the water pump body 1. The full welding process is used to ensure the connection strength and build a stable foundation for subsequent components.

[0029] The front of the mounting plate 2 is precision milled to create symmetrically distributed limiting grooves 21. The inner walls of the limiting grooves 21 are straight and smooth, providing precise guidance for the sliding of the limiting slider 22, ensuring that its movement trajectory is strictly limited and smooth. The inner wall of the limiting groove 21 is fitted with the limiting slider 22, allowing the limiting slider 22 to move quickly and smoothly within it. A hydraulic damping rod 23 is bolted to the inner bottom wall of the limiting groove 21. The hydraulic damping rod 23 is made of high-precision, high-damping performance professional hydraulic components, with a fine internal structure and well-sealed moving parts. The upper end of the hydraulic damping rod 23 and the lower end of the limiting slider 22 are firmly connected by welding, including a plug, a precision throttling orifice, and suitable hydraulic oil, ensuring precise and efficient force transmission. The inner bottom wall of the limiting slide groove 21 is also fixedly connected by welding to a buffer spring 24. The buffer spring 24 is made of high-quality spring steel with a spring coefficient that has been rigorously tested and has undergone a fine heat treatment process to ensure stable and durable elasticity. One end of the buffer spring 24 is fixedly welded to the lower end of the limiting slider 22, forming a stable elastic buffer system that works in conjunction with the hydraulic damping rod 23 to cope with vibration and impact.

[0030] The front of the mounting plate 2 features a finely designed quick-release mechanism, making the installation and removal of the controller body 34 easy and convenient, greatly improving daily operation and maintenance efficiency.

[0031] The quick-release mechanism includes a mounting housing 3, the back of which is firmly fixed to the front of two limit sliders 22 by welding, ensuring that the mounting housing 3 moves synchronously with the shock absorption mechanism in a vibration environment, providing stable support for the internal controller.

[0032] The inner rear wall of the housing 3 is fixedly connected by welding with symmetrically distributed stop blocks 31. The stop blocks 31 are ingeniously designed, providing a positioning reference for the installation of subsequent components and limiting unnecessary displacement to a certain extent. The front of the stop blocks 31 is fixedly connected by welding with guide rods 32. The guide rods 32 are straight and smooth, providing precise guidance for the insertion of the limiting plate 33 and ensuring its accurate movement path. The outer gaps of the two guide rods 32 are matched with the limiting plate 33, allowing the limiting plate 33 to be flexibly inserted and removed.

[0033] The back of the limiting plate 33 is in close contact with the front of the stop block 31 to ensure accurate initial installation position. The controller body 34 is fixedly installed on the front of the limiting plate 33 by screws. The controller body 34 adopts advanced electronic control technology and integrates multiple functional modules. It can accurately control the operation of the water pump according to parameters such as light intensity, water level change, and water pressure fluctuation. The inner bottom wall of the mounting housing 3 is drilled to open a threaded hole 35. The hole diameter, pitch and other parameters of the threaded hole 35 are precisely matched with the screw 36, providing a reliable foundation for the screw 36 to be screwed in and out.

[0034] The inner wall of the threaded hole 35 is precisely threaded into the screw 36. The screw 36 is made of high-strength stainless steel, is straight and has good rigidity. Its lower end extends precisely to the bottom of the mounting housing 3 for easy operation. The lower end of the screw 36 is fixedly connected to the drive handle 37 by welding. The drive handle 37 adopts an ergonomic arc design with anti-slip texture on the surface, making it easy for the operator to grip and apply force, and easily control the rotation of the screw 36. The upper end of the screw 36 is rotatably connected to the limit block 38 through a high-precision bearing. The bearing is a ball bearing with high load capacity and low coefficient of friction to ensure that the screw 36 rotates smoothly without jamming. The limit block 38 can flexibly rise and fall with the screw 36.

[0035] The upper end of the limiting block 38 is milled to form a limiting slot 39. The shape and size of the limiting slot 39 are adapted to the lower end of the limiting plate 33 to ensure precise insertion. The inner walls on both sides of the limiting slot 39 are milled to form symmetrically distributed flared bevels 310. The angle of the flared bevels 310 is carefully designed. Based on the principle of inclined plane mechanics, it can convert the vertical displacement into horizontal compressive force during the upward movement of the limiting block 38, so as to achieve precise positioning of the limiting plate 33. The gap between the inner wall of the limiting slot 39 and the lower end of the limiting plate 33 is adapted to achieve smooth movable insertion.

[0036] The inner bottom wall of the housing 3 is fixedly connected by welding to symmetrically distributed guide sleeves 311. The inner top wall of the guide sleeve 311 is fitted with the movable rod 312 with a gap, and the movable rod 312 can move smoothly up and down in it, providing stable guidance for the lifting and lowering of the limit block 38 and preventing it from deviating and shaking. The upper ends of the two movable rods 312 are firmly fixedly connected to the lower end of the limit block 38 by welding, ensuring stable and reliable force transmission.

[0037] The working process of this utility model:

[0038] Step 1: When the water pump starts running, vibration is inevitable. The vibration is transmitted to the mounting plate 2. At this time, the hydraulic damping rod 23 and the buffer spring 24 in the limit slide groove 21 work together. The hydraulic damping rod 23 consumes vibration energy through the flow resistance of the internal liquid according to the principle of fluid mechanics, and slows down the up and down movement speed of the limit slider 22 caused by vibration. At the same time, the buffer spring 24 uses its own elasticity to help absorb vibration energy during compression and rebound, so that the mounting housing 3 fixedly connected to the limit slider 22 remains relatively stable, thereby effectively protecting the controller body 34 installed in the housing from severe vibration and impact.

[0039] Step two: When the operator prepares to install the controller body 34, first align the limiting plate 33 fixed on the back of the controller body 34 with the guide rod 32 inside the mounting housing 3, so that the limiting plate 33 is inserted along the guide rod 32. When the limiting plate 33 contacts the stop block 31, it indicates that the controller has been initially positioned. Next, the operator rotates the drive handle 37 at the lower end of the screw 36. The screw 36 is screwed upward through thread engagement with the threaded hole 35 on the bottom wall of the mounting housing 3. The limiting block 38, which is rotatably connected to the upper end of the screw 36 through the bearing, rises accordingly. Due to the flared inclined surface 310 design of the limiting slot 39 at the upper end of the limiting block 38, during the rising process... The inclined plane contacts the lower end of the limiting plate 33. Utilizing the mechanical principle of the inclined plane, the vertical displacement is converted into a horizontal squeezing force, causing the limiting plate 33 to move slightly to both sides and precisely engage in the limiting slot 39, thus completing the stable installation of the controller and ensuring that the controller will not loosen or fall off under the vibration environment of the water pump operation. When disassembling, the operator rotates the drive handle 37 in the opposite direction, and the screw 36 drives the limiting block 38 to descend, releasing the squeezing force between the limiting slot 39 and the limiting plate 33. At this time, the controller body 34 is held and pulled outward, allowing the limiting plate 33 to slide out along the guide rod 32, and the controller can be easily removed from the mounting housing 3.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
