Description

Technical Field

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

[0002] The most significant characteristic of deep well pumps is that the motor and pump are integrated into one unit. They are submerged in groundwater wells to draw and transport water, and are widely used in agricultural irrigation and drainage, industrial and mining enterprises, urban water supply and drainage, and sewage treatment. However, most existing deep well pumps lack anti-collision structures. When lowered into a deep well, the pump is prone to collisions with the well wall, causing damage and severely impacting its lifespan. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a new type of high-efficiency deep well pump.

[0004] The purpose of this utility model can be achieved through the following technical solution: a new type of high-efficiency deep well pump, including a pump body, characterized in that the pump body is provided with a buffer protection component that can reduce the impact force of collision, the buffer protection component including an outer protective cylinder coaxially sleeved on the pump body and a plurality of anti-collision rubber strips for reducing the intensity of collision.

[0005] The anti-collision rubber strip has a circular arc protrusion structure in its cross section;

[0006] The inner wall of the outer protective cylinder and the outer shell of the pump body are provided with several buffer chambers arranged in a honeycomb ring shape. Each buffer chamber is equipped with an elastic buffer strip, which can effectively absorb the impact energy generated by mechanical collision.

[0007] Several triangular support chambers are provided between the inner wall of the outer protective cylinder and the pump body. These support chambers are evenly distributed circumferentially along the outer wall of the pump body. The triangular structure design effectively improves the overall structural stability.

[0008] The outer protective cylinder is connected to the pump body shell through an integrated structure of buffer chamber and support chamber, forming an integral structure with both vibration reduction and load-bearing functions.

[0009] In the aforementioned high-efficiency new deep well pump, the arc-shaped raised surface of the anti-collision rubber strip has a wave-shaped anti-slip texture, and multiple anti-collision rubber strips are embedded in a circumferential direction along the outer peripheral wall of the outer protective cylinder at intervals.

[0010] In the aforementioned high-efficiency new deep well pump, the elastic buffer strip can be made of gradient density polyurethane material, with its density decreasing radially from the outside to the inside.

[0011] Compared with existing technologies, this new high-efficiency deep well pump has the following advantages:

[0012] 1. By combining honeycomb buffer chambers and gradient density elastic strips, energy is absorbed step by step, reducing peak impact force, and the wave pattern of its anti-collision rubber strips further disperses collision energy.

[0013] 2. The geometric rigidity design of the triangular support chamber enhances the overall resistance to deformation, ensuring the stable operation of the deep well pump under complex working conditions. The multi-layer protective structure reduces direct damage to the pump body's core components from mechanical collisions, lowers the failure rate, and extends the equipment's lifespan.

[0017] 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.

[0018] like Figure 1 , Figure 2 As shown, this high-efficiency new deep well pump includes a pump body 1. The pump body 1 is equipped with a buffer protection component to reduce the impact force of collisions. The buffer protection component includes an outer protective cylinder 2 coaxially sleeved on the pump body 1 and multiple anti-collision rubber strips 3 for reducing the intensity of collisions. The anti-collision rubber strips 3 have a circular arc convex structure in cross section. Between the inner wall of the outer protective cylinder 2 and the outer shell of the pump body 1, there are several buffer chambers 4 arranged in a honeycomb ring pattern. Each buffer chamber 4 is embedded with an elastic buffer strip 5, which can effectively absorb the impact energy generated by mechanical collisions. Between the inner wall of the outer protective cylinder 2 and the pump body 1, there are also several support chambers 6 with a triangular structure. The support chambers 6 are evenly distributed circumferentially along the periphery of the outer shell of the pump body 1. The triangular structure design effectively improves the overall structural stability. The outer protective cylinder 2 is connected to the outer shell of the pump body 1 through the integrated structure of the buffer chambers 4 and the support chambers 6, forming an integral structure with dual functions of vibration reduction and load bearing. The arc-shaped raised surface of the anti-collision rubber strip 3 has a wave-shaped anti-slip texture. Multiple anti-collision rubber strips 3 are embedded in a circular direction along the outer peripheral wall of the outer protective cylinder 2 at intervals. The elastic buffer strip 5 can be made of gradient density polyurethane material, and its density is distributed in a gradient decreasing distribution from the outside to the inside in the radial direction.

[0019] The outer protective sleeve 2 is coaxially fitted onto the outer shell of the pump body 1 to form the first layer of physical protection. The anti-collision rubber strip 3 adopts a rounded convex cross section and a wave-shaped anti-slip texture on the surface, which can not only disperse the impact force of external collisions, but also increase frictional resistance and prevent the pump body 1 from shifting due to vibration or collision.

[0020] The buffer chamber 4 is arranged in a honeycomb ring pattern between the inner wall of the outer protective cylinder 2 and the pump body 1. It is filled with elastic buffer strips 5 made of gradient-density polyurethane material. The porous nature of the honeycomb structure can evenly disperse impact energy, while the gradient-density material (dense on the outside and sparse on the inside) absorbs energy layer by layer, significantly reducing the damage to the pump body 1 from instantaneous impacts. The support chamber 6 is evenly distributed around the circumference of the pump body 1. Its triangular structure enhances overall stability through geometric rigidity, preventing the outer protective cylinder 2 from deforming due to impact. It also forms a "rigid-flexible" protective system with the buffer chamber 4. The outer protective cylinder 2 and the pump body 1 are integrated through the buffer chamber 4 and the support chamber 6, ensuring vibration damping while improving load-bearing capacity and reducing the risk of component loosening.
