TECHNICAL FIELD

[0001] The present application relates to the technical field of water pump. More particularly, the present application relates to a pump filter with adjusting function. BACKGROUND

[0002] As a necessary tool for underwater operation, the water pump undertakes an indispensable task in water operation. For some pumps that are used in water or downhole, sand particles and gravel that float in water are easily sucked into the water pump during the pumping operation, which may affect the operation of the water pump and cause the pump to be stopped for maintenance, thereby affecting the work progress. Although there are technologies for setting filters at the water inlet or other positions of the pump to filter the floating sand particles and the raised gravel, the filter holes of such technologies will still be blocked over time, the effect will gradually weaken, and maintenance is relatively frequent.

[0003] In view of the above, the present application provides a pump filter with adjusting function to improve the above-mentioned technical problems. SUMMARY

[0004] In order to overcome the shortcomings that the filter holes of the existing pump filter will be blocked and maintenance is relatively frequent, the present application provides a pump filter with adjusting function.

[0005] The technical scheme is as follows: A pump filter with adjusting function comprises a filter cylinder and a circular ring one, the filter cylinder is slidably connected with the circular ring one, further comprises a fixing ring, a bearing, an elastic tube, a hollow ring, a circular ring two, a circular rod and a spring, the circular ring one is connected with the fixing ring, the inner side of the fixing ring is fixedly connected with the bearing, the filter cylinder is fixedly connected with a plurality of elastic tubes, the inner side of the filter cylinder is fixedly connected with the hollow ring, the inner side of the hollow ring is slidably connected with the circular ring two, the circular ring two is fixedly connected with a plurality of circular rods, the circular rods are slidably connected with the hollow ring, and the circular rods are fixedly connected with the circular ring one, a cavity one is formed between the lower side of the circular ring two and the hollow ring, a cavity two is formed between the upper side of the circular ring two and the hollow ring, a plurality of through grooves are formed in the circular ring two, the cavity one is communicated with the cavity two through the through grooves, a plurality of springs are fixedly connected with the lower side of the circular ring two, and the springs are fixedly connected with the hollow ring.

[0006] As an improvement of the above-mentioned scheme, the pump filter with adjusting function further comprises a pipeline, the pipeline is fixedly connected between the hollow ring and the filter cylinder, the pipeline is communicated with the cavity one, a channel is formed in the filter cylinder, the channel is communicated with the pipeline, both open ends of the elastic tube are fixedly connected with the filter cylinder, a plurality of cavities three are formed in the filter cylinder, the middle part of the outer side of the elastic tube is located in the cavity three, and the cavity three is communicated with the channel.

[0007] As an improvement of the above-mentioned scheme, the filter cylinder, the circular ring one, the fixing ring and the bearing are all made of rust-proof material.

[0008] As an improvement to the above solution, the pump filter with adjustment function has a flange on the upper part of the filter cartridge.

[0009] As an improvement to the above solution, in the above-mentioned pump filter with adjustment function, the circular ring and the fixed ring are detachably connected.

[0010] As an improvement to the above solution, a sealing ring is provided on the outer ring surface of the aforementioned pump filter with adjustment function.

[0011] As an improvement to the above solution, the pump filter with adjustment function also includes a protection component, which includes a piston, a first limiting ring, and a second limiting ring; the piston is slidably connected to the inside of the pipe; the first limiting ring is fixed to the inside of the pipe and is located above the piston; the second limiting ring is fixed to the inside of the pipe and is located below the piston.

[0014] As an improvement to the above solution, in the above-mentioned pump filter with adjustment function, the elastic tube is made of puncture-resistant material.

[0015] Beneficial effects: First, it is used to intercept impurities and prevent impurities in the water from flowing into the pump and interfering with its operation. At the same time, the hollow ring, the second ring, the round rod and the spring work together to dampen the drive unit and ensure its service life. The second ring, which is used to dampen the drive unit, can also be used to control the reciprocating expansion and contraction of the elastic tube, so that the elastic tube intermittently squeezes the impurities located inside it, which can immediately remove the impurities in the early stage of accumulation and effectively prevent blockage. Second, by cooperating with the piston and the limiting ring, the pressure oil flowing into cavity three is restricted, preventing excessive pressure oil from flowing into cavity three when the vibration intensity of the drive unit is high. This would avoid problems such as excessive deformation of the elastic tube and insufficient pressure oil passing through the through groove, thus preventing excessive deformation of the elastic tube from affecting the pumping operation. At the same time, it can also prevent the damping effect from decreasing. In addition, by blocking the pressure oil with the stop block, the resistance of the pressure oil passing through the through groove is increased, thereby improving the kinetic energy dissipation capacity and improving the damping effect on the drive unit.

Detailed Implementation

[0018] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0019] Example 1: A pump filter with regulating function, such as Figures 1-5As shown, the system includes a filter cartridge 1 and a first ring 2; the first ring 2 is slidably connected to the filter cartridge 1; it also includes a fixed ring 3, a bearing 4, an elastic tube 5, a hollow ring 201, a second ring 202, a round rod 203, and a spring 204; the fixed ring 3 is connected to the first ring 2, and the fixed ring 3 is made of metal; the bearing 4 is fixedly connected to the inner side of the fixed ring 3; several elastic tubes 5 are fixedly connected to the filter cartridge 1; the hollow ring 201 is welded to the inner side of the filter cartridge 1; the second ring 202 is slidably connected to the inner side of the hollow ring 201; four round rods 203 are fixedly connected to the second ring 202. Rod 203, round rod 203 is slidably connected to hollow ring 201, round rod 203 is fixedly connected to circular ring 1 2; a cavity 92 is formed between the lower side of circular ring 202 and hollow ring 201; a cavity 93 is formed between the upper side of circular ring 202 and hollow ring 201; several through grooves 94 are opened on circular ring 202; cavity 1 92 is connected to cavity 2 93 through through grooves 94; twelve springs 204 are fixedly connected to the lower side of circular ring 202, springs 204 are fixedly connected to hollow ring 201, and springs 204 are made of alloy material.

[0020] It also includes a pipe 205; the hollow ring 201 is fixedly connected to the filter cartridge 1 by the pipe 205, which is connected to the cavity 92. The pipe 205 can be made of plastic or metal. The filter cartridge 1 has a channel 95, which is connected to the pipe 205. The two open ends of the elastic tube 5 are fixedly connected to the filter cartridge 1. The filter cartridge 1 has several cavities 96, and the outer middle part of the elastic tube 5 is located in the cavity 96, which is connected to the channel 95.

[0021] The filter cartridge 1, the circular ring 2, the fixing ring 3, and the bearing 4 are all made of rust-proof material for rust prevention.

[0022] The filter cartridge 1 has a flange 91 on its upper part. During installation, the flange 91 is snapped onto the water pump, and then bolts are used to lock the flange 91 onto the water pump.

[0023] The circular ring 2 and the fixed ring 3 are detachably connected, and the fixed ring 3 can be replaced to accommodate different types of drive units 6.

[0024] A sealing ring is provided on the outer ring surface of the ring 2. The ring 2 drives the sealing ring to slide on the inner side of the filter cylinder 1, so that the sealing effect can be guaranteed when the ring 2 slides on the inner side of the filter cylinder 1.

[0025] First, manually pass the output shaft of the drive unit 6 downward through the bearing 4, and insert the protrusion of the drive unit 6 near the output shaft into the retaining ring 3. The screw on the drive unit 6 passes through the retaining ring 3, and then the external nut is screwed to the lower end of the screw of the drive unit 6 to lock the drive unit 6 onto the retaining ring 3. Then, the filter cartridge 1 is installed on the water pump, and the output shaft of the drive unit 6 is connected to the turbine of the water pump to complete the assembly of the entire water pump. At this time, the inlet of the water pump is surrounded by the filter cartridge 1. When it is submerged in the water for pumping, floating debris such as sand and gravel will be filtered and intercepted by the filter cartridge 1 to prevent the water pump from sucking in such impurities and causing the pump to become clogged and damaged.

[0026] During this period, a sealing ring can be added between the fixed ring 3 and the drive unit 6 to achieve a sealing effect; in addition to providing the installation function for the drive unit 6, the filter cartridge 1 can also intercept impurities in the water through the elastic tube 5 on the filter cartridge 1, so as to prevent impurities in the water from flowing into the water pump and interfering with its operation; when in use, the filter cartridge 1 can be used as a mounting bracket for the drive unit 6, and can also be used to intercept impurities, so as to prevent impurities in the water from flowing into the water pump and interfering with its operation.

[0027] Because the drive unit 6 vibrates during operation, the tightness of its mounting position gradually loosens over time, leading to a decrease in its installation stability. Therefore, pressure oil is filled into cavities 1 (92) and 2 (93). When the drive unit 6 vibrates downwards, it drives the fixed ring 3 and bearing 4 downwards. The fixed ring 3 drives the circular ring 2 downwards, which in turn drives the circular rod 203 downwards. The circular rod 203 then drives the circular ring 202 downwards, compressing the spring 204. During this process, the circular ring 202 squeezes the pressure oil in cavity 1 (92), causing it to flow through the through groove 94 into cavity 2 (93). When the drive unit 6 vibrates upwards, the spring... Under the combined action of the rebound force of 204, the drive unit 6 drives the first ring 2, the round rod 203 and the second ring 202 to move upward back to their original positions. The drive unit 6 continues to vibrate, causing the second ring 202 to move up and down reciprocally inside the hollow ring 201. This causes the pressure oil in the first cavity 92 and the second cavity 93 to continuously pass through the through groove 94 for exchange. When the pressure oil passes through the narrow through groove 94, it will be resisted and heated up, thus converting kinetic energy into heat energy, reducing the power of the second ring 202, thereby damping the drive unit 6. In use, the hollow ring 201, the second ring 202, the round rod 203 and the spring 204 work together to dampen the drive unit 6, ensuring the service life of the drive unit 6 and the installation stability of the drive unit 6.

[0028] When there are too many impurities in the water (such as floating sand or stirred-up mud), the impurities will block the elastic tube 5. Therefore, a pipe 205 is added to the hollow ring 201. The pipe 205, channel 95, and cavity 3 96 are also filled with pressurized oil. During the vibration damping of the drive unit 6 by the ring 202, the ring 202 moves downward to squeeze the pressurized oil in cavity 1 92, causing some of the pressurized oil in cavity 1 92 to flow into the pipe 205, and then from the pipe 205 into channel 95 and cavity 3 96, and then squeeze the elastic tube 5, causing the elastic tube 5 to deform towards its centerline. When the ring 202 moves upward, it will draw some of the pressurized oil in the pipe 205, channel 95, and cavity 3 96 back into cavity 1 92, so that the pressurized oil in cavity 3 96 contains When the pressure inside cavity 96 decreases, the deformed channel 95 springs back to its original shape. The second ring 202 continues its up-and-down reciprocating motion during the damping operation, causing the elastic tube 5 to expand and contract. This intermittently squeezes impurities located inside the elastic tube 5, effectively removing them in the early stages of accumulation and preventing blockages. In use, the second ring 202, used for damping the drive unit 6, can also control the reciprocating expansion and contraction of the elastic tube 5, causing it to intermittently squeeze impurities located inside. This effectively removes impurities in the early stages of accumulation and prevents blockages. It should be noted that the two open ends of the elastic tube 5 are fixedly connected to the filter cartridge 1, and the elastic tube 5 remains sealed to the filter cartridge 1 even when it deforms.

[0029] Example 2, based on Example 1, such as Figure 6 and Figure 7 As shown, it also includes a protective assembly, which includes a piston 206, a first limiting ring 207, and a second limiting ring 208; the piston 206 is slidably connected to the inside of the pipe 205; the first limiting ring 207 is fixedly connected to the inside of the pipe 205 and is located above the piston 206; the second limiting ring 208 is fixedly connected to the inside of the pipe 205 and is located below the piston 206; the piston 206 is limited inside the pipe 205 by the cooperation of the first limiting ring 207 and the second limiting ring 208.

[0030] A humidity sensor is installed on the upper side of the ring 2. Since there are seals between the filter cartridge 1, the ring 2, the fixed ring 3, the bearing 4 and the drive unit 6, the performance of the seals will deteriorate after long-term use. When water leaks through the seals into the space on the upper side of the ring 2, the humidity sensor can detect the increase in air humidity and promptly remind the workers to perform maintenance operations.

[0031] It also includes a stop block 209; several stop blocks 209 are fixedly connected to each through slot 94 of the second annulus 202.

[0032] The elastic tube 5 is made of puncture-resistant material, such as high-strength flexible metal and high-strength flexible rubber, to improve service life.

[0033] When the vibration amplitude of the drive unit 6 is too large, the stroke of the reciprocating motion of the second ring 202 will increase, resulting in more pressure oil being squeezed into the third cavity 96. This increases the deformation of the elastic tube 5, thereby reducing its permeability and interfering with the pumping operation. Furthermore, with more pressure oil flowing into the pipe 205, channel 95, and third cavity 96, the amount of pressure oil flowing into the second cavity 93 decreases. This means that when the second ring 202 moves downward, the amount of pressure oil passing through the through groove 94 from the second cavity 93 decreases, causing the second ring 202 to be hollow. When the inner side of ring 201 moves upward, the amount of pressure oil in cavity 2 93 is insufficient to provide effective damping. Therefore, a protective component is added to the inner side of pipe 205. When ring 202 moves downward, it squeezes the pressure oil in cavity 1 92, causing the pressure oil to push piston 206 downward. Piston 206 squeezes the pressure oil in pipe 205, causing some of the pressure oil in pipe 205 and channel 95 to flow into cavity 3 96, thereby controlling the deformation of elastic tube 5. When ring 202 moves upward, piston 206 moves with the pressure oil... The piston moves upward back to its original position, where it is blocked and limited by the limiting ring 207, preventing it from detaching from the pipe 205. When the vibration amplitude of the drive unit 6 is too large, the downward stroke of the ring 202 increases, causing the pressure oil to push the piston 206 a greater distance until it contacts the limiting ring 208. At this point, the limiting ring 208 blocks and limits the piston 206, preventing it from compressing the pressure oil below it. This stops the pressure oil content in the cavity 96 from rising, effectively preventing excessive deformation of the elastic tube 5. At this time, the pressure oil in cavity 1 92 can only move through the through groove 94 to cavity 2 93, so that the pressure oil can fully participate in the damping operation, thereby ensuring the damping effect. In use, the piston 206 and the limiting ring 208 cooperate to restrict the pressure oil flowing into cavity 3 96, so as to avoid excessive pressure oil flowing into cavity 3 96 when the vibration intensity of drive part 6 is high, which would cause excessive deformation of elastic tube 5 and insufficient pressure oil passing through through groove 94. This avoids excessive deformation of elastic tube 5 and affects the pumping operation, and also prevents the damping effect from decreasing.

[0034] When the pressurized oil passes through the through groove 94, the stop block 209 inside the through groove 94 will block and limit the pressurized oil, thereby increasing the resistance of the pressurized oil passing through the through groove 94, thereby increasing the kinetic energy reduction capability, which is beneficial to improving the shock absorption effect on the drive unit 6.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
