Description

Technical Field

[0001] The present invention belongs to the technical field of water pump housing detection, and specifically refers to a detection device for a water pump housing. Background Art

[0002] The pump housing is one of the important structural components of the pump. It is usually a housing made of materials such as steel, cast iron, stainless steel, and aluminum alloy, surrounding the main components of the pump, such as the impeller, shaft, etc.

[0003] For existing water pump housings, such as the pump housing of a submersible pump, after production, it is necessary to detect the sealing performance of the housing. Most of the existing sealing detection schemes for the pump housing of a submersible pump are to introduce the pump housing into a pipeline for gas pressurization, and then submerge it in water to observe whether bubbles will be generated in the water, so as to judge whether the sealing performance of the pump housing is qualified. However, the detection results of this detection method are actually not easy to observe, and it is also difficult to understand where the sealing problem specifically occurs in the pump housing. Therefore, it is necessary to propose a detection device for a water pump housing. Summary of the Invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a detection device for a water pump housing, effectively solving the problems that the existing sealing detection method for a water pump housing is not easy to observe and it is difficult to understand where the sealing defect specifically occurs in the pump housing.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a detection device for a water pump housing, including an automatic sealing component, a vibration operation component, a water storage tank, a water outlet head, a corrugated extension pipe, an equipment base, a surrounding bracket, and a sealing component bracket. The vibration operation component is arranged on the equipment base, the surrounding bracket is fixedly connected to the equipment base, the sealing component bracket is fixedly connected to the surrounding bracket, the automatic sealing component is arranged on the sealing component bracket, the water storage tank is fixedly connected to the top inside the surrounding bracket, the water outlet head is arranged on the water storage tank in several groups, and the corrugated extension pipe is arranged on the water outlet head.

[0006] Preferably, the automatic sealing component includes a T-shaped guiding bracket, a T-shaped guiding groove, an auxiliary spring, a spring support platform, a T-shaped connecting rod, a sealing cover, a sealing motor, a driving turntable, a driving swing rod, and a reciprocating sliding column. The T-shaped guiding bracket is fixedly connected to the sealing component bracket, the T-shaped guiding groove is arranged in the T-shaped guiding bracket, several groups of the sealing covers are fitted and slidably arranged in the T-shaped guiding groove, the spring support platforms are fixedly connected to both sides of the T-shaped guiding bracket, the T-shaped connecting rod penetrates and slides through one end of the T-shaped guiding bracket, the auxiliary spring is connected between the spring support platform and the T-shaped connecting rod, the body of the sealing motor is arranged on the surrounding bracket, the driving turntable is arranged on the output end of the sealing motor, the reciprocating sliding column is fitted and slidably arranged on the vertical part of the T-shaped guiding groove, one end of the driving swing rod is hinged to the driving turntable, and the other end of the driving swing rod is hinged to the reciprocating sliding column.

[0007] Furthermore, the vibration operation assembly includes a submersible pump housing, a limiting ring, an intermittent motor, a conveyor belt mechanism, a conveyor support platform, a vibration spring, a vibration guide post, and a vibration sliding groove. The vibration sliding grooves are arranged in an array on the equipment base. The vibration guide posts are fitted and slidably arranged on the vibration sliding grooves. The conveyor support platform is fixedly connected to the top of the vibration guide posts. The vibration spring is arranged between the bottom of the conveyor support platform and the equipment base. The conveyor belt mechanism is arranged on the conveyor support platform. The intermittent motor is arranged on the conveyor belt mechanism and can control the intermittent conveyance of the conveyor belt mechanism. The submersible pump housings are arranged in multiple groups on the conveyor belt mechanism. The limiting ring is fixedly connected to the inner wall of the submersible pump housing.

[0008] Wherein, a detection layer is adhesively provided on the side wall of the sealing cover, and the detection layer is made of water-soluble paper.

[0009] Furthermore, the T-shaped connecting rod is in contact connection with the sealing cover.

[0010] Furthermore, the reciprocating sliding post is in contact connection with the top of the sealing cover.

[0011] Furthermore, the rotation frequency of the output end of the intermittent motor corresponds to the pressing frequency of the reciprocating sliding post, ensuring that each time the conveyor belt mechanism moves, the reciprocating sliding post can just press the sealing cover against the limiting ring.

[0012] The beneficial effects achieved by the present invention with the above structure are as follows: This solution provides a detection device for a water pump pump housing, effectively solving the problems that the existing sealing detection method for the water pump pump housing is not easy to observe and it is difficult to know where the specific sealing defect of the pump housing occurs. This method has the following advantages:

[0013] (1) To solve the problem that the existing detection method for the sealing performance of a water pump casing is not easy to observe, the present invention proposes an automatic sealing component and a vibration operation component. When the sealing motor and the intermittent motor are started, the turntable is driven to rotate. By driving the swing rod, the reciprocating sliding column slides back and forth in the vertical part of the T-shaped guide groove. Then, the reciprocating sliding column that slides back and forth pushes the sealing cover located in the vertical part of the T-shaped guide groove downward. The sealing cover enters the submersible pump casing from the vertical part of the T-shaped guide groove and is buckled on the limiting ring. The reciprocating sliding column continues to move downward, and the force is transmitted to the conveying support platform through the conveyor belt mechanism. Then, the vibration spring drives the conveying support platform to vibrate downward. During this process, the vibration guide column enters the vibration sliding groove. When the reciprocating sliding column slides upward, the conveying support platform moves upward and resets through the vibration spring. The intermittent motor controls the intermittent movement of the conveyor belt mechanism, so that several groups of submersible pump casings move to the left in sequence, and the submersible pump casings are sealed one by one, which is convenient for subsequent sealing detection. Moreover, during the sealing process, the vibration effect on the water in the submersible pump casing is realized through the downward vibration action, further increasing the movement amplitude of the water in the submersible pump casing and improving the intensity of the sealing detection, making the detection result more reliable.

[0014] (2) After the sealing cover in the vertical part of the T-shaped guide groove enters the submersible pump casing, the sealing cover in the horizontal part of the T-shaped guide groove immediately replenishes the vertical part of the T-shaped guide groove through the auxiliary spring, ensuring that every time the conveyor belt mechanism moves, the reciprocating sliding column can just buckle the sealing cover on the limiting ring, which is convenient for cyclic detection and operation.

[0015] (3) By stretching the corrugated extension pipe, multiple groups of submersible pump casings can be freely filled with water. After filling with water, the corrugated extension pipe is taken out, and then the subsequent detection operations can be continued, which is relatively convenient. Brief Description of the Drawings

[0028] The automatic sealing assembly 1 includes a T-shaped guiding bracket 9, a T-shaped guiding groove 10, an auxiliary spring 11, a spring supporting platform 12, a T-shaped connecting rod 13, a sealing cover 14, a sealing motor 15, a driving turntable 16, a driving swing rod 17 and a reciprocating sliding column 18. The T-shaped guiding bracket 9 is fixedly connected to the sealing assembly bracket 8. The T-shaped guiding groove 10 is arranged in the T-shaped guiding bracket 9. The sealing cover 14 is fitted and slidably arranged in the T-shaped guiding groove 10 in several groups. The spring supporting platform 12 is fixedly connected to both sides of the T-shaped guiding bracket 9. The T-shaped connecting rod 13 is slidably arranged through one end of the T-shaped guiding bracket 9. The auxiliary spring 11 is connected between the spring supporting platform 12 and the T-shaped connecting rod 13. The body of the sealing motor 15 is arranged on the surrounding bracket 7. The driving turntable 16 is arranged on the output end of the sealing motor 15. The reciprocating sliding column 18 is fitted and slidably arranged on the vertical part of the T-shaped guiding groove 10. One end of the driving swing rod 17 is hinged to the driving turntable 16, and the other end of the driving swing rod 17 is hinged to the reciprocating sliding column 18.

[0029] The vibration operation assembly 2 includes a submersible pump housing 19, a limiting ring 20, an intermittent motor 21, a conveyor belt mechanism 22, a conveying support platform 23, a vibration spring 24, a vibration guiding column 25 and a vibration sliding groove 26. The vibration sliding grooves 26 are arranged in an array on the equipment base 6. The vibration guiding columns 25 are fitted and slidably arranged on the vibration sliding grooves 26. The conveying support platform 23 is fixedly connected to the top of the vibration guiding column 25. The vibration spring 24 is arranged between the bottom of the conveying support platform 23 and the equipment base 6. The conveyor belt mechanism 22 is arranged on the conveying support platform 23. The intermittent motor 21 is arranged on the conveyor belt mechanism 22 and can control the intermittent conveyance of the conveyor belt mechanism 22. The submersible pump housings 19 are arranged in multiple groups on the conveyor belt mechanism 22. The limiting rings 20 are fixedly connected to the inner walls of the submersible pump housings 19.

[0030] A detection layer 27 is attached to the side wall of the sealing cover 14, and the detection layer 27 is made of water-soluble paper.

[0031] The T-shaped connecting rod 13 is in contact connection with the sealing cover 14.

[0032] The reciprocating sliding column 18 is in contact connection with the top of the sealing cover 14.

[0033] The rotation frequency of the output end of the intermittent motor 21 corresponds to the pressing frequency of the reciprocating sliding column 18, ensuring that every time the conveyor belt mechanism 22 moves, the reciprocating sliding column 18 can just press the sealing cover 14 against the limiting ring 20.

[0034] During specific use, first, by stretching the corrugated extension pipe 5, multiple groups of submersible pump housings 19 can be freely filled with water. After filling, the corrugated extension pipe 5 is taken out, and then the subsequent detection operations can be continued, which is relatively convenient. Start the sealing motor 15 and the intermittent motor 21. Then, drive the turntable 16 to rotate, and drive the reciprocating sliding column 18 to reciprocate in the vertical part of the T-shaped guide groove 10 through the driving swing rod 17. Thus, the reciprocating sliding column 18 that reciprocates downward pushes the sealing cover 14 located in the vertical part of the T-shaped guide groove 10 downward. The sealing cover 14 enters the submersible pump housing 19 from the vertical part of the T-shaped guide groove 10 and is buckled on the limiting ring 20. Then, the reciprocating sliding column 18 continues to move downward, and the force is transmitted to the conveying support table 23 through the conveyor belt mechanism 22, and then the conveying support table 23 is driven to vibrate downward through the vibration spring 24. During this process, the vibration guide column 25 enters the vibration sliding groove 26. When the reciprocating sliding column 18 slides upward, the conveying support table 23 moves upward and resets through the vibration spring 24. The intermittent motor 21 controls the intermittent movement of the conveyor belt mechanism 22, so that several groups of submersible pump housings 19 move to the left in sequence, and the submersible pump housings 19 are sealed one by one, which is convenient for subsequent sealing detection. Moreover, during the sealing process, the vibration effect of the water in the submersible pump housing 19 is realized through the downward vibration action, further increasing the movement amplitude of the water in the submersible pump housing 19 and improving the intensity of the sealing detection, making the detection result more reliable. If there are defects in the sealing performance of the submersible pump housing 19, then during the vibration process of the above-mentioned submersible pump housing 19, a part of the water in the submersible pump housing 19 will flow out from the defective positions around the sealing cover 14. If a small amount of water flows out from the side wall of the sealing cover 14, a part of the detection layer 27 located on the side will be dissolved by water. After the detection is completed, just observe the degree of dissolution by water on several groups of detection layers 27 to judge the sealing performance of the submersible pump housing 19. Observe several groups of detection layers 27. If there is no dissolved part, it indicates that the sealing performance of the submersible pump housing 19 is qualified. If there is a dissolved part on the detection layer 27, it indicates that the sealing performance of the submersible pump housing 19 is unqualified. And the position where the detection layer 27 is dissolved corresponds to the position with sealing defects on the sealing cover 14, which is convenient for observation and can quickly understand where the pump housing has sealing defects. After the sealing cover 14 in the vertical part of the T-shaped guide groove 10 enters the submersible pump housing 19, the sealing cover 14 in the horizontal part of the T-shaped guide groove 10 is immediately supplemented to the vertical part of the T-shaped guide groove 10 through the auxiliary spring 11, ensuring that every time the conveyor belt mechanism 22 moves once, the reciprocating sliding column 18 can just buckle the sealing cover 14 on the limiting ring 20, which is convenient for cyclic detection and operation.
