According to the stainless steel deep-well pump with the high sealing performance, when water flow is sucked upwards by the pump body, the flowing water flow drives blades to move, then a rotating shaft and a connecting rod are driven to rotate, the connecting rod rotates to drive a brush plate to move, and the brush plate moves to clean the inner wall of a filter cover and sweep away gravel clamped in filter holes, so that the situation that the gravel blocks the filter holes is avoided; due to the fact that the flow speed of water is reduced through rotation of the blades, gravels can be precipitated and enter the lower half portion of the filtering cover through the non-return plate, and when water flow reversely flows through upward movement, only few gravels reversely rise to the positions of the blades.

Description

Technical Field

[0001] The utility model relates to the technical field of deep well pumps, in particular to a high-sealing stainless steel deep well pump. Background Art

[0002] A deep well pump is a device specially used to extract groundwater or liquid from a deep well. It generates centrifugal force by driving the impeller to rotate through an electric motor to pump the liquid to the surface. It has the characteristics of high efficiency, long-distance transmission and strong adaptability. It is widely used in the fields of farmland irrigation, urban water supply, industrial water use, etc., providing a reliable water source for various water conservancy projects and water supply systems.

[0003] However, existing deep well pumps usually have filtering devices installed inside the equipment. However, due to the small size of the equipment, they often lack the function of discharging the filtered mud and sand out of the equipment. Since there are hard particles such as silica in the mud and sand, these particles will rub against the inner wall of the deep well pump for a long time, which will cause the waterproof performance of the deep well pump to be damaged, thereby reducing the service life of the deep water pump. In view of this, we propose a high-sealing stainless steel deep well pump. Utility Model Content

[0004] The utility model aims to provide a stainless steel deep well pump with high sealing performance to solve the problems raised in the above background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a high-sealing stainless steel deep well pump, comprising a pump body, the outer wall of the pump body is fixedly connected with a mounting ring, the mounting ring is fixedly connected to a filter cover by a threaded bolt, the outer wall of the filter cover is fixedly connected with a filter hole, a filter assembly is arranged inside the filter cover, and the filter assembly comprises:

[0006] The inner wall of the filter cover is fixedly connected with a mounting frame, the mounting frame is sleeved with the rotating shaft, and the side wall of the rotating shaft is fixedly connected with the blade;

[0007] A brush plate, wherein the side wall of the rotating shaft is fixedly connected with a connecting rod, and one end of the connecting rod away from the rotating shaft is fixedly connected to the brush plate;

[0008] Baffle 1, the outer wall of the filter cover is fixedly connected with baffle 1;

[0009] Baffle plate 2: the outer wall of the filter cover is fixedly connected with baffle plate 2.

[0010] Preferably, a check plate is fixedly connected to the inner wall of the filter cover, a guide block is fixedly connected to the inner bottom of the filter cover, a through hole is fixedly connected to the inner wall of the filter cover, and an opening is provided at the bottom of the baffle plate 2.

[0011] Preferably, the inner wall of the filter cover is fixedly connected to the sealing ring, and the sealing ring is sleeved with the mounting ring to improve the sealing degree between the filter cover and the pump body.

[0012] Preferably, the brush plate abuts against the inner wall of the filter cover, and the brush plate is in lateral contact with the filter hole located on one side of the inner wall of the filter cover.

[0013] Preferably, the baffle plate 1 and the baffle plate 2 are arranged at an angle, and the baffle plate 1 and the baffle plate 2 are inclined downward, so as to guide the settling mud and sand and prevent the mud and sand from settling around the filter cover.

[0014] Preferably, the check plate is provided with a large diameter end and a small diameter end, the large diameter end is located on the side close to the blades, and the small diameter end is located on the side away from the blades. The particles passing through the filter holes are precipitated due to the rotation of the blades which reduces the flow rate of water, and the gravel enters the lower part of the filter cover through the check plate. Due to the setting of the check plate, when the water flows upward, only a small amount of gravel will rise in the opposite direction to the blade position.

[0015] Compared with the prior art, the utility model provides a high-sealing stainless steel deep well pump, which has the following beneficial effects:

[0016] 1. The high-sealing stainless steel deep well pump has a mounting frame, a rotating shaft, blades, a connecting rod, a brush plate, a baffle plate 1 and a baffle plate 2. The baffle plate 1 and the baffle plate 2 are inclined downward to guide the sedimentation of mud and sand, so as to prevent the mud and sand from settling around the filter cover. The mud and sand are blocked by the filter holes, but when the particle size of the sand and gravel is similar to the size of the filter holes, they will be stuck in the filter holes. When the water flow is sucked upward by the pump body, the flowing water flow drives the blades to move, and then drives the rotating shaft and the connecting rod to rotate. The rotation of the connecting rod drives the brush plate to move. The movement of the brush plate cleans the inner wall of the filter cover and sweeps off the sand and gravel stuck in the filter holes to prevent the sand and gravel from clogging the filter holes. By arranging a filter assembly under the pump body, the filter device is pulled out of the pump body and the filter device can be disassembled at the same time, so as to improve the portability of the device, prevent the sand and gravel from wearing the pump body, improve the sealing of the pump body and extend the service life of the deep water pump.

[0017] 2. The high-sealing stainless steel deep well pump has a check plate, a guide block, a through hole and an opening. Since the rotation of the blades disturbs the water flow and reduces the water flow rate, gravel will settle. The gravel enters the lower part of the filter cover through the check plate. Due to the setting of the check plate, even if the water flow moves upward and reverses, only a small amount of gravel will rise in the opposite direction to the blade position. The gravel settled in the lower part of the filter cover is discharged from the filter cover through the through hole and the opening, thereby improving the filtering effect of the filter device on gravel.

DETAILED DESCRIPTION

[0025] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: a high-sealing stainless steel deep well pump, including a pump body 1, the outer wall of the pump body 1 is fixedly connected with a mounting ring 2, the mounting ring 2 is fixedly connected to a filter cover 3 by threaded bolts, the outer wall of the filter cover 3 is fixedly connected with a filter hole 5, the interior of the filter cover 3 is provided with a filter assembly, the filter assembly includes a mounting frame 6, a rotating shaft 7, blades 8, a connecting rod 9, a brush plate 10, a baffle 1 11, a baffle 2 12, a check plate 13, a guide block 14, a through hole 15 and an opening 16.

[0026] In one embodiment of the utility model, the inner wall of the filter cover 3 is fixedly connected to the sealing ring 4, and the sealing ring 4 is sleeved with the mounting ring 2 to improve the sealing degree between the filter cover 3 and the pump body 1, the inner wall of the filter cover 3 is fixedly connected with a mounting frame 6, and the mounting frame 6 is sleeved with the rotating shaft 7, and the side wall of the rotating shaft 7 is fixedly connected with a blade 8, and the side wall of the rotating shaft 7 is fixedly connected with a connecting rod 9, and the end of the connecting rod 9 away from the rotating shaft 7 is fixedly connected with a brush plate 10, and the brush plate 10 is abutted against the inner wall of the filter cover 3, and the brush plate 10 is in lateral contact with the filter hole 5 located on the side of the inner wall of the filter cover 3, and the outer wall of the filter cover 3 is fixedly connected with a baffle 11, and the outer wall of the filter cover 3 is fixedly connected with a baffle 2 12, and the baffle 11 and the baffle 2 12 are inclined. The second plate 12 is inclined downward to guide the sedimentation of mud and sand to prevent the mud and sand from settling around the filter cover 3. The inner wall of the filter cover 3 is fixedly connected with a check plate 13, the inner bottom of the filter cover 3 is fixedly connected with a guide block 14, the inner wall of the filter cover 3 is fixedly connected with a through hole 15, and the bottom of the baffle 12 is provided with an opening 16. The check plate 13 is provided with a large diameter end and a small diameter end. The large diameter end is located on the side close to the blade 8, and the small diameter end is located on the side away from the blade 8. The particles passing through the filter hole 5 are precipitated because the rotation of the blade 8 reduces the flow rate of water, and the gravel enters the lower half of the filter cover 3 through the check plate 13. Due to the setting of the check plate 13, when the water flows upward, only a small amount of gravel will rise in the opposite direction to the position of the blade 8.

[0027] The pump body 1 starts to work, and sucks water into the filter cover 3 through the filter hole 5. The water flow is pumped upward along the filter cover 3 and the pump body 1. The baffle 1 11 and the baffle 2 12 are tilted. The baffle 1 11 and the baffle 2 12 are tilted downward to guide the sedimentation of mud and sand, and prevent the mud and sand from settling around the filter cover 3, thereby reducing the amount of mud and sand around the filter cover 3. The mud and sand are blocked by the filter hole 5, but when the particle size of the gravel is similar to that of the filter hole 5, it will be stuck in the filter hole 5. When the water flow is sucked upward by the pump body 1, the flowing water flow drives the blade 8 to move, and then drives the rotating shaft 7 and the connecting rod 9 to rotate. The rotation of the connecting rod 9 drives the brush plate 10 to move. The brush plate 10 moves to clean the inner wall of the filter cover 3, sweeps off the gravel stuck in the filter hole 5, and prevents the gravel from clogging the filter hole 5.

[0028] In addition, a check plate 13 is fixedly connected to the inner wall of the filter cover 3, a guide block 14 is fixedly connected to the inner bottom of the filter cover 3, a through hole 15 is fixedly connected to the inner wall of the filter cover 3, an opening 16 is provided at the bottom of the baffle 12, and the check plate 13 is provided with a large diameter end and a small diameter end, the large diameter end is located on the side close to the blade 8, and the small diameter end is located on the side away from the blade 8. When the size of the particles is smaller than the filter hole 5, the filter hole 5 will not be able to block the passage of the particles. Since the rotation of the blade 8 reduces the flow rate of water, gravel will settle, and the gravel will enter the lower half of the filter cover 3 through the check plate 13. Due to the setting of the check plate 13, even if the water flow moves upward and reverses, only a small amount of gravel will rise in the opposite direction to the position of the blade 8, and the gravel settled in the lower half of the filter cover 3 will be discharged from the filter cover 3 through the through hole 15 and the opening 16.
