Description

Technical Field

[0001] This utility model belongs to the field of pumps, and relates to a deep well pump, and particularly to a high-efficiency deep well pump. Background Technology

[0002] A deep well pump is a machine that is submerged in a well to extract water. It is a type of pump that is immersed in a groundwater well to draw and transport water, and is widely used in farmland irrigation and drainage, industrial and mining enterprises, rural drinking water, and water extraction from deep groundwater.

[0003] Currently, deep well pumps on the market have a filter screen at the bottom of the body. The function of the filter screen is to filter out impurities such as mud, sand, and stones in the water, preventing impurities from entering the pump with the water and damaging the internal mechanical structure. However, prolonged use can cause the filter screen to become clogged, and users may not be aware of this. If the deep well pump is used in this case, negative pressure will form inside the pump. If the negative pressure persists for a long time, it can easily cause the deep well pump to be damaged and scrapped. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a high-efficiency deep well pump.

[0005] The purpose of this utility model can be achieved through the following technical solution: a high-efficiency deep well pump, including a pump head with a water inlet port, characterized in that a filter cylinder for filtering impurities is provided at the water inlet port of the pump head, and a cleaning device for cleaning impurities attached to the filter cylinder is also provided inside the water inlet port.

[0006] The filter cartridge has a U-shaped structure and is fixedly connected to the inside of the water inlet port of the pump head;

[0007] The cleaning device includes multiple rotatable cleaning rollers, a drive disc that can move the cleaning rollers, and a fixing ring adapted to the water inlet port of the pump head.

[0008] The drive disc is fixedly connected to the end of the output shaft of the deep well pump drive motor, and its output shaft passes through the center of the bottom of the filter cylinder.

[0009] The cleaning rollers are circumferentially spaced on the drive disc. Each cleaning roller has a connecting shaft and a transmission shaft at both ends. The connecting shaft is fixedly connected to the drive disc. The end of the transmission shaft is provided with a bearing. Each cleaning roller has a cleaning brush on the outside for cleaning the impurities attached to the filter cartridge.

[0010] The fixed ring is provided with a guide ring groove, which has an inverted T-shaped cross section. Multiple cleaning rollers are connected to the guide ring groove through a drive shaft and bearing components to form an axial limiting and circumferential sliding connection.

[0011] In the aforementioned high-efficiency deep well pump, the filter cylinder is connected to the pump head inlet port via internal and external thread engagement, and the rotation axis of the drive disc coincides with the central axis of the filter cylinder. The drive disc is located inside the filter cylinder and has a gap between it and the inner wall of the filter cylinder.

[0012] In the aforementioned high-efficiency deep well pump, there is a movable gap between the bearing component and the inner wall of the guide ring groove, the movable gap being 0.5-1mm.

[0013] Compared with existing technologies, this high-efficiency deep well pump has a simple structural design. Through a composite motion cleaning device, the filter cartridge is cleaned in real time, reducing the frequency of downtime maintenance. The matching design of the guide ring groove and bearing components ensures stable movement of the cleaning roller and avoids jamming. At the same time, the filter cartridge adopts internal and external thread connection, which can be easily disassembled, replaced or cleaned later. Attached Figure Description

Detailed Implementation

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figure 1 , Figure 2 , Figure 3As shown, this high-efficiency deep well pump includes a pump head 1 with an inlet port. A filter cartridge 2 for filtering impurities is installed at the inlet port of the pump head 1. A cleaning device for cleaning impurities adhering to the filter cartridge 2 is also installed inside the inlet port. The filter cartridge 2 has a U-shaped structure and is fixedly connected inside the inlet port of the pump head 1. The cleaning device includes multiple rotatable cleaning rollers 3, a drive disc 4 that can move the cleaning rollers 3, and a fixing ring 5 adapted to the inlet port of the pump head 1. The drive disc 4 is fixedly connected to the output shaft end of the deep well pump drive motor. The output shaft passes through the center of the bottom of the filter cylinder 2. The cleaning rollers 3 are circumferentially spaced on the drive disk 4. Each cleaning roller 3 has a connecting shaft 6 and a drive shaft 7 at both ends. The connecting shaft 6 is fixedly connected to the drive disk 4. The end of the drive shaft 7 is provided with a bearing 8. Each cleaning roller 3 has a cleaning brush 9 on the outside, which is used to clean the impurities attached to the filter cylinder 2. The fixing ring 5 is provided with a guide ring groove 10. The guide ring groove 10 has an inverted T-shaped cross section. Multiple cleaning rollers 3 are axially limited and circumferentially sliding connected by the drive shaft 7 and the bearing 8 and the guide ring groove 10.

[0020] The above-mentioned structure is simple in design. The cleaning device with compound motion cleans the filter cartridge 2 in real time, reducing the frequency of downtime maintenance. The design of the guide ring groove 10 and the bearing component 8 ensures the stable movement of the cleaning roller 3 and avoids jamming.

[0021] The filter cartridge 2 is connected to the inlet port of the pump head 1 via internal and external threads. The rotation axis of the drive disc 4 coincides with the central axis of the filter cartridge 2. The drive disc 4 is located inside the filter cartridge 2 and has a gap between it and the inner wall of the filter cartridge 2. The filter cartridge 2 uses internal and external thread connections, which facilitates disassembly, replacement, or cleaning in the future.

[0022] There is a movable gap between the bearing component 8 and the inner wall of the guide ring groove 10, which is 0.5-1mm.

[0023] When the deep well pump is running, water enters through the inlet port and passes through the U-shaped filter cylinder 2 to filter impurities. The drive motor drives the drive disc 4 to rotate, and the drive disc 4 causes the cleaning roller 3 to rotate synchronously through the connecting shaft 6. At the same time, the transmission shaft 7 slides in the guide ring groove 10, realizing the combined circumferential and axial motion of the cleaning roller 3. During the movement, the cleaning brush 9 continuously scrapes the inner wall of the filter cylinder 2 to remove attached impurities and prevent clogging.

[0024] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0025] Although this document uses a lot of technical terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any kind of additional limitation would contradict the spirit of this invention.
