Description

Technical Field

[0001] The invention relates to the technical field of pump body detection, in particular to a water pump detection device based on a circulating water system. Background Art

[0002] A circulating water system is a water treatment and delivery system used in industrial, commercial or residential buildings. It saves water and improves energy efficiency by reusing water resources. This system is widely used in air conditioning cooling, heating, industrial process cooling and various applications that require continuous water flow. The water pump is one of the core components of the circulating water system. Its main function is to ensure that water can flow along the predetermined route.

[0003] The water pump in the circulating water system is constantly in contact with the water flow during operation. The water contains solid particles (such as soil, sand, rust, etc.). These substances will cause wear to the inside of the pump body when circulating in the pump body. Therefore, it is necessary to conduct wear resistance testing on this type of water pump to ensure that the wear resistance inside the pump body meets the subsequent use requirements. At present, when conducting wear resistance testing, multiple external pump bodies are directly connected to the upper flange of the water pump in turn, and different types of abrasives (mud, sand, particles and rust, etc.) are pumped into the water pump to simulate the situation in actual use. After a period of time, the water pump is taken out and the wear condition inside the water pump is observed or tested to obtain the wear resistance of the water pump.

[0004] The current wear resistance testing process has the following problems: a batch of water pumps are usually tested during the test, and when connecting the water pump, the flange on the water pump needs to be docked with the pipe on the external pump body, and then the abrasive is tested. When the abrasive is replaced later, it needs to be manually disassembled and reinstalled for docking. If the entire process is performed manually, the test of a water pump will take a lot of time and cost, and the overall efficiency is low. In addition, the position of the water pump is not limited in the above process, so the stability of the water pump is poor during the docking process and the subsequent wear resistance testing process.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0034] like Figure 1 and Figure 2 As shown, a water pump detection device based on a circulating water system includes:

[0035] A bottom plate 1 is provided with a placement groove 10, and a fixing unit 2 for fixing the water pump base is arranged on the bottom plate 1. The fixing unit 2 includes a moving column 20. Two moving columns 20 that are symmetrically distributed on the left and right and have vertical axes slide up and down and penetrate through the bottom plate 1. A T-shaped plate 21 located above the bottom plate 1 is fixedly sleeved on the moving column 20. The two T-shaped plates 21 are symmetrical on the left and right, and two front-to-back symmetrical limiting cylinders 22 are fixedly arranged on the longitudinal section of the T-shaped plate 21.

[0036] like Figure 1 and Figure 2As shown, the right end face of the bottom plate 1 is provided with a fixed column 3 with a vertical axis through a connecting frame, and an annular plate 30 is provided on the fixed column 3 for sliding up and down. The annular plate 30 is driven by an external hydraulic cylinder (not shown in the figure) to move up and down. A plurality of mounting frames 31 evenly distributed in the circumferential direction are fixedly provided on the annular plate 30, and a flange 32 is fixedly provided on the mounting frame 31. A pipe 33 is fixedly provided on the upper end face of the flange 32. The pipes 33 corresponding to the plurality of mounting frames 31 are respectively connected to an external pump body (such as a mud pump, a sand pump, and a particle pump, etc.), and a plurality of circumferentially distributed docking columns 34 are fixedly provided on the lower end face of the flange 32. In order to improve the stability of the overall structure, a reinforcing rod can be connected between the mounting frame 31 and the fixed column 3.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, a guide mechanism 4 for guiding the flange 32 to dock with the flange on the water pump is commonly provided between the mounting frame 31 and the base plate 1, the guide mechanism 4 comprises a vertical column 40, a vertical column 40 with a vertical axis and located on the left side of the placement groove 10 is fixedly provided on the base plate 1, a movable plate 400 is slidably provided up and down on the vertical column 40, a connecting rod 401 is fixedly provided on the movable plate 400 and the mounting frame 31, and a docking tube 402 with an opening at the lower end is fixedly provided on the lower end surface of the connecting rod 401 via a spring telescopic rod.

[0038] During operation, the water pump housing to be inspected is first placed on the bottom plate 1, and the water pump base is placed in the placement groove 10. In the process of the water pump being moved down and placed in the placement groove 10, the pump body base is initially guided by the fixing unit 2, and then the mounting frame 31 is manually rotated so that the flange 32 for the abrasive to be inspected is rotated to the top of the pump body. Then, the external hydraulic cylinder drives the annular plate 30 to move down, and the annular plate 30 drives the docking tube 402 to move down synchronously through the mounting frame 31, and the docking tube 402 is connected to the corresponding moving column 2. 0 cooperate with each other to guide the downward movement of the mounting frame 31 and the flange 32 thereon, so that the flange 32 is located at the specified docking position, and at the same time, the T-shaped plate 21 in the fixing unit 2 drives the limiting cylinder 22 to move downward synchronously through the cooperation between the docking cylinder 402 and the moving column 20, and the limiting cylinder 22 is inserted into the corresponding mounting hole on the pump body base. Finally, the T-shaped plate 21 presses the water pump base. The horizontal base is positioned by the above placement method, and the pump body is fixed on the bottom plate 1 at the same time. At this time, the upper flange of the pump body is located at the specified docking position.

[0039] As the annular plate 30 drives the corresponding mounting frame 31 and flange 32 to continue to move downward, the docking column 34 on the flange 32 passes through the through hole on the water pump flange, and finally the flange 32 presses the flange on the water pump, and the pipeline 33 is connected with the inner cavity of the water pump. Then the corresponding external pump body works to pump the corresponding abrasive into the water pump and flows out from the front end opening of the water pump, so as to perform a wear resistance test on the inner wall of the inner cavity of the water pump. After the test operation is completed, the test water pump is taken out, and the wear condition inside the water pump is visually observed or photographed by a miniature camera, and the wear resistance is judged by the degree of wear.

[0040] After completing the above-mentioned single abrasive inspection, the external hydraulic cylinder works to move the annular plate 30 upward, and the annular plate 30 is rotated to rotate the mounting frame 31 corresponding to another abrasive to above the bottom plate 1, and the above-mentioned operation is repeated to perform the inspection operation of another abrasive, and the above-mentioned process is repeated to perform the inspection operation of different types of abrasives. After the inspection of the water pump is completed, the water pump is taken out and replaced with the next water pump for inspection.

[0041] like Figure 2 and Figure 3 As shown, a guide tube 403 is fixedly provided on the lower end surface of the docking tube 402, and the guide tube 403 is in the shape of a truncated cone with a small diameter section facing upward.

[0042] When the docking tube 402 moves downward to cooperate with the moving column 20 , the docking tube 402 drives the guide tube 403 to move downward synchronously. The inner arc surface of the guide tube 403 first contacts the moving column 20 to guide the moving column 20 to move into the docking tube 402 .

[0043] like Figure 1 and Figure 3 As shown, the guiding mechanism 4 also includes an L-shaped frame 41, and two bonding plates 410 with symmetrical cross-sections in the length direction are fixedly provided on the movable plate 400 and the mounting frame 31 through the L-shaped frame 41, and the upper end surfaces of the corresponding two bonding plates 410 are jointly fixed with an arc-shaped lower pressure plate 411 through a vertical rod.

[0044] like Figure 1 and Figure 3 As shown, a pressing groove 412 is formed on the outer arc surface of the pressing plate 411 corresponding to the movable plate 400 , and a pressing block 413 is fixedly provided on the pressing plate 411 corresponding to the mounting frame 31 .

[0045] During operation, the left movable plate 400 is first moved upward manually, so that the movable plate 400 drives the bonding plate 410 and the lower pressure plate 411 to move upward synchronously, which is convenient for the placement of the water pump. Then, when the mounting frame 31 moves downward to connect the upper flange 32 with the water pump flange, the mounting frame 31 drives the L-shaped frame 41 and the bonding plate 410 thereon to move downward synchronously, and the bonding plate 410 drives the lower pressure block 413 thereon to move downward synchronously. After the lower pressure block 413 moves down to the lower pressure groove 412 of the left lower pressure plate 411, it presses the left lower pressure plate 411 and moves downward synchronously. Therefore, the two lower pressure plates 411 located above the water pump move downward synchronously and press the upper end of the water pump. The stability of the subsequent pumping of abrasives for testing is improved by the above-mentioned locking method of the water pump.

[0046] As the L-shaped frame 41 moves downward, the two bonding plates 410 on the L-shaped frame 41 move downward accordingly and gradually fit tightly against the front and rear sides of the water pump. The front and rear directions of the water pump are limited by the cooperation between the two corresponding bonding plates 410, thereby improving the accuracy and stability of the subsequent docking between the flange plate 32 and the flange on the water pump.

[0047] like Figure 1 , Figure 3 and Figure 4 As shown, the guiding mechanism 4 also includes a longitudinal bar 42. The connecting rod 401 is fixedly sleeved with the longitudinal bar 42 located above the docking tube 402. The lower end surface of the longitudinal bar 42 is fixedly provided with two front-to-back symmetrical plug-in columns 420. The upper end surface of the base plate 1 is provided with four matrix-arranged plug-in slots 421.

[0048] like Figure 1 , Figure 4 and Figure 5 As shown, the fixing unit 2 also includes a sliding rod 23, and the front and rear end surfaces of the inner wall of the placement groove 10 are both slidably provided with a sliding rod 23 with an axis extending from front to back, and the opposite surfaces of the two sliding rods 23 are fixedly provided with a fixing plate 230, and a spring 231 mounted on the sliding rod 23 is fixedly provided between the fixing plate 230 and the inner wall of the placement groove 10, and the opposite surfaces of the upper ends of the two fixing plates 230 are chamfered, and the left and right end surfaces of the inner wall of the placement groove 10 are both slidably provided with a sliding rod 232 with an axis extending from left to right, and the opposite surfaces of the two sliding rods 232 are fixedly provided with a fixing plate 233.

[0049] like Figure 1 , Figure 4 and Figure 5As shown, the fixed unit 2 also includes a push plate 24, and the left and right two sliding rods 232 are both slidably sleeved with push plates 24, a spring three 240 is fixedly provided between the push plate 24 and the fixed plate 233, a spring four 241 is fixedly provided between the push plate 24 and the inner wall of the placement groove 10, and the front and rear end surfaces of the T-shaped plate 21 are both fixedly provided with inclined bars 242, and the upper end surface of the push plate 24 is fixedly provided with a matching column 245 that matches the inclined bar 242 through a connecting bar.

[0050] During operation, the staff first places the water pump to be tested in the placement groove 10. During the placement process, the water pump base squeezes the upper chamfers of the two fixing plates 230, so that the two fixing plates 230 move away from each other, and the spring 231 is compressed. When the base is placed in the placement groove 10, the elastic force generated by the deformation of the spring 231 causes the two fixing plates 230 to press the front and rear sides of the base respectively, completing the preliminary fixation of the front and rear directions of the base.

[0051] Then, during the downward movement of the corresponding mounting frame 31 above the bottom plate 1, the mounting frame 31 drives the connecting rod 401 thereon to move downward synchronously, and the connecting rod 401 drives the longitudinal bar 42, the spring telescopic rod and the docking tube 402 to move downward synchronously. After the moving column 20 is inserted into the docking tube 402, the docking tube 402 pushes the moving column 20 to move downward synchronously, and the moving column 20 drives the T-shaped plate 21 thereon to move downward synchronously. During the downward movement of the T-shaped plate 21, the T-shaped plate 21 drives the inclined bar 242 thereon to move downward synchronously, and the inclined bar 242 and the corresponding The cooperation of the matching column 245 enables the matching column 245 to drive the push plate 24 to move, and the two push plates 24 approach each other. The two push plates 24 respectively drive the corresponding fixed plate 233 to approach the left and right sides of the pump body base through the spring three 240. The spring four 241 is stretched, and when the fixed plate 233 contacts the water pump base, it stops moving. The spring three 240 is compressed, and the elastic force generated by the compression of the spring three 240 causes the fixed plate 233 to press the base tightly, so the two fixed plates 233 cooperate with each other to clamp the left and right side walls of the base.

[0052] As the T-shaped plate 21 continues to move downward, the T-shaped plate 21 drives the limiting cylinder 22 thereon to be clamped into the mounting hole on the base, and the base is limited again. Finally, the T-shaped plate 21 moves downward to press the upper end surface of the base, and the base is pressed down and limited to the bottom plate 1, completing the upper and lower limiting process of the base. In summary, the limiting clamping of the pump body is completed and the upper flange of the pump body is at the specified docking position.

[0053] It should be noted that when the T-shaped plate 21 presses the upper end surface of the base, the connecting rod 401 and the longitudinal bar 42 continue to move downward, the docking tube 402 stops moving downward, the spring telescopic rod is compressed, and the longitudinal bar 42 drives the plug-in column 420 thereon to continue to move downward and finally insert into the plug-in slot 421. Through the mutual cooperation of the four plug-in columns 420 and the corresponding plug-in slots 421, the plug-in columns 420, the connecting rod 401, the mounting frame 31, and the movable plate 400 together form a rectangular frame surrounding the pump body, thereby improving the stability during subsequent wear resistance testing.

[0054] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the fixing unit 2 also includes an L-shaped plate 25, the lower end surface of the base plate 1 is fixedly provided with the L-shaped plate 25, the horizontal section of the L-shaped plate 25 is slidably provided with a center plate 250, the upper end surface of the center plate 250 is slidably penetrated by a center column 251, the upper end surface of the center column 251 is fixedly provided with a rectangular plate 252, a spring 253 sleeved on the center column 251 is fixedly provided between the rectangular plate 252 and the center plate 250, a through groove 254 penetrating to the placement groove 10 is opened on the lower end surface of the base plate 1, and a limiting column 255 corresponding to the limiting cylinder 22 is fixedly provided on the upper end surface of the rectangular plate 252.

[0055] like Figure 5 As shown, the limiting cylinder 22 is composed of a cylindrical section and a truncated cone section with a small diameter section facing downward from top to bottom. The diameter of the limiting column 255 is the same as the inner diameter of the limiting cylinder 22. The lower opening of the limiting cylinder 22 and the upper end of the limiting column 255 are both chamfered.

[0056] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the fixed unit 2 also includes a driving group 26 arranged on the base plate 1, and the driving group 26 includes a fixed frame 260. Two left-right symmetrical fixed frames 260 are fixedly arranged on the lower end surface of the base plate 1. A swing bar 261 is rotatably arranged on the fixed frame 260 through a fixed axis. The two swing bars 261 are staggered front and back, and movable grooves 262 are provided at both ends of the left and right sides of the swing bar 261. A rectangular block 263 is fixedly arranged on the lower end surface of the moving column 20, and a spring 264 sleeved on the moving column 20 is fixedly arranged between the rectangular block 263 and the base plate 1. A receiving groove 265 is provided on the rectangular block 263 and the center plate 250, and a sliding column 266 is fixedly arranged in the receiving groove 265, and the sliding column 266 is located in the corresponding movable groove 262.

[0057] During operation, when the mounting frame 31 moves to the top of the bottom plate 1 and continues to move downward, the lower pressing block 413 presses the lower pressing plate 411 on the moving plate 400 so that the moving plate 400 moves downward synchronously. When the mounting frame 31 and the docking tube 402 on the moving plate 400 move downward to the top of the moving column 20 and press the moving column 20 to move downward synchronously, the moving column 20 drives the rectangular block 263 to move downward synchronously, the spring six 264 is stretched, and the rectangular block 263 is connected to the movable groove on the corresponding swing bar 261 through the sliding column 266 thereon. The cooperation between 262 makes the part of the swing bar 261 located below the center position of the bottom plate 1 swing upward, and the sliding column 266 on the center plate 250 is driven to move upward synchronously through the synchronous swing of the two swing bars 261, and then the center plate 250 drives the center column 251 and the rectangular plate 252 to move upward synchronously, and the rectangular plate 252 drives the limiting column 255 thereon to pass through the mounting hole at the corresponding position on the water pump base. The pump body base is preliminarily guided in the above manner, so that the subsequent limiting cylinder 22 is convenient for being inserted into the corresponding mounting hole.

[0058] As the movable column 20 continues to move downward, the center plate 250 continues to move upward, the spring five 253 is compressed, and the limiting column 255 is maintained in the corresponding mounting hole. Then the movable column 20 drives the T-shaped plate 21 and the limiting cylinder 22 to move downward synchronously until the conical section on the limiting cylinder 22 contacts the inner wall of the corresponding mounting hole, and adjusts the base position while contacting. As the limiting cylinder 22 continues to move downward, the vertical section of the limiting cylinder 22 is inserted into the corresponding mounting hole, and the limiting column 255 is inserted into the limiting cylinder 22 at the same time. Therefore, at this time, the limiting column 255 and the limiting cylinder 22 are plugged into each other, which improves the stability of the water pump fixation.
