Description

Technical Field

[0001] This utility model relates to the field of water pump technology, and in particular to a novel set of inlet and outlet equipment for a vertical water pump. Background Technology

[0002] Traditional water pumps typically use Y-shaped filters at the inlet. However, Y-shaped filters are prone to causing turbulence and generating air bubbles. Therefore, a distance of 5-8 times the pipe diameter is needed before the water enters the pump to ensure a smooth flow and extend the pump's lifespan. The connection method is either flange or butt welding. However, Y-shaped filters, which also use flanges or butt welding, have several drawbacks. First, a long pipe is required at the inlet, necessitating significant space. Second, metal flexible conduits have a limited lifespan, requiring replacement every 3-5 years. Replacement damages the original insulation layer and is time-consuming and cumbersome to install. Third, installation requires on-site open flames and electricity, and welding slag inside the pipes needs to be removed. Finally, maintenance is difficult. Because the entire pump inlet and outlet are connected by flanges or butt welding, many bolts and other components need to be disassembled for repair or replacement if problems occur, resulting in high maintenance costs.

[0003] Currently, Chinese patent CN202707475U discloses a novel vertical water pump inlet and outlet assembly, including an inlet pipe, a water pump, and an outlet pipe, which are connected sequentially. A flow guide filter is provided between the inlet pipe and the water pump. Supports are provided at the bottom of both the flow guide filter and the outlet pipe bend. A butterfly valve is installed on the inlet pipe, and a butterfly valve and a check valve are installed on the outlet pipe. The key feature is that the water pump is vertically positioned between the flow guide filter and the outlet pipe, with the inlet and outlet pipes located on the left and right sides of the pump. The advantages of this invention are: its structure significantly reduces the floor space and footprint of the pump room, reduces weight, decreases pressure on the ground, has a service life consistent with the pipeline life, and allows for quick, simple, and clean installation with low maintenance costs; it also ensures a smooth water flow into the pump and provides vibration damping.

[0004] The aforementioned existing technical solutions have the following drawbacks: the lack of filtration measures leads to excessive impurities in the water during suction. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of vertical water pump inlet and outlet complete set of equipment to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A novel vertical water pump inlet and outlet assembly includes a water pump, a filter module installed at the water pump inlet, and a connection module installed at the water pump outlet. The filter module includes a frame and a cover plate. The cover plate is welded and fixed to the top of the frame. A mounting hole is provided at the center of the top of the cover plate. The bottom end of the water pump is fixedly installed in the mounting hole, and the water pump inlet is located inside the frame. A filter screen is fixedly installed on the outside of the frame. Multiple threaded holes are provided on the top of the cover plate, and lifting rings are screwed into the threaded holes. Multiple support rods are inserted into the bottom of the frame.

[0007] By adopting the above technical solution, when groundwater needs to be drained in some areas, there is a lot of sand and gravel in the groundwater. If all the sand and gravel are sucked out by suction, the natural filter layer formed by the underground sand and gravel may fail, causing the water quality to deteriorate rapidly. Therefore, by setting the filter screen to a mesh size that can just isolate the sand and gravel, and then expanding the area of ​​the entire filter module, the water pump can be able to draw out enough clean water, avoiding the problem of easy clogging caused by placing the filter device in the water pump inlet.

[0008] In a further embodiment, the frame is a cylindrical frame, and the outer wall diameter of the frame gradually decreases from top to bottom.

[0009] By adopting the above technical solution, the water pump will vibrate during operation. When sand and gravel get stuck on the filter screen, the vibration of the motor will cause the sand and gravel to fall downwards, giving the filter screen a certain self-cleaning ability.

[0010] In a further embodiment, the bottom end of the support rod has a pointed structure, and multiple square rods are spaced apart at the bottom end of the support rod.

[0011] By adopting the above technical solution, the support rod is used to create a certain gap between the bottom of the frame and the bottom of the well, so as to prevent it from sinking directly into the silt at the bottom of the well.

[0012] In a further embodiment, the filter screen has a circular mesh structure.

[0013] By adopting the above technical solution, it is possible to intercept gravel as much as possible, and the round hole is easy to process.

[0014] In a further embodiment, the connection module consists of a pipe fitting and a clamp.

[0015] By adopting the above technical solution, the clamp can quickly connect the pipe to the pipe joint.

[0016] In a further embodiment, a sealing ring is fitted on the outer end of the pipe fitting that connects to the water pipe.

[0017] In summary, this utility model has the following beneficial effects: 1. By setting the filter screen to a mesh size that can just separate sand and gravel, and then increasing the area of ​​the entire filter module, the water pump can draw out enough clean water, thus avoiding the problem of easy clogging caused by placing the filter device in the water pump inlet.

The filter module 2 includes a frame and a cover plate. The cover plate is welded and fixed to the top of the frame. An installation hole is provided at the center of the top of the cover plate. The bottom end of the water pump 1 is fixedly installed in the installation hole, and the inlet of the water pump 1 is located inside the frame. A filter screen is fixedly installed on the outside of the frame. Multiple threaded holes are provided on the top of the cover plate, and lifting rings are screwed into the threaded holes. Multiple support rods are inserted into the bottom of the frame. The frame is a cylindrical frame, and the outer diameter of the frame gradually decreases from top to bottom. The water pump vibrates during operation. When sand and gravel get stuck on the filter screen, the vibration of the motor will cause the sand and gravel to fall downwards, giving the filter screen a certain self-cleaning ability. The bottom end of the support rod has a pointed structure, and multiple square rods are spaced apart at the bottom end of the support rod. The mesh of the filter screen has a circular structure. The connection module 3 consists of a pipe joint and a clamp. A sealing ring is fitted on the outer end of the pipe joint that connects to the water pipe.
