Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] Because current air conditioning systems typically use energy-saving water pumps that are fixed to the installation location with bolts, when they need to be disassembled and repaired, workers need to use specialized tools to loosen multiple bolts to remove them, which wastes repair time and reduces repair efficiency.

[0032] This utility model provides a water pump assembly for an air conditioning system, such as... Figures 1 to 5 As shown, the device includes a motor 1, a coupling 2, and a water suction box 3. Mounting seats 4 are fixedly mounted at the lower ends of the motor 1 and the water suction box 3. Bases 5 are movably mounted at the lower ends of both mounting seats 4. Limiting frames 18 are fixedly mounted on the bases 5, allowing the mounting seats 4 connected to the water suction box 3 to contact each other. A fixed chamber 6 and a drive chamber 7 are located inside the base 5. Two first screws 8 are rotatably mounted inside the fixed chamber 6. Lifting plates 9 are threadedly connected to the two first screws 8. Lifting blocks 10 are fixedly mounted on the lifting plates 9. There are four lifting blocks 10. A fixing block 11 is fixedly mounted on the upper end of each lifting block 10, passing through the fixed chamber 6. The fixing block 11 is L-shaped, with one end inserted into the mounting seat 4. A rotating rod 12 is rotatably mounted inside the drive chamber 7. A handle 13 is fixedly mounted on one end of the rotating rod 12, passing through the drive chamber 7. Two drive bevel gears 14 are fixedly mounted on the rotating rod 12. The lower end of each first screw 8 extends into the drive chamber 7 and is fixedly mounted with a driven bevel gear 15.

[0033] It should be noted that when a water pump needs to be installed in the air conditioning system, the entire water pump is placed on the base 5, so that the mounting seat 4 near the water suction box 3 contacts the limiting bracket 18. The mounting seat 4 is provided with a fixing groove that cooperates with the fixing block 11, so that the fixing groove is exactly aligned with the fixing block 11. Turn the handle 13, the handle 13 drives the rotating rod 12 to rotate, the rotating rod 12 drives the driving bevel gear 14 to rotate. Since the driving bevel gear 14 is meshed with the driven bevel gear 15, the driven bevel gear 15 rotates. The driven bevel gear 15 drives the first screw 8 to rotate, so that the lifting plate 9 moves downward. The lifting plate 9 drives the lifting block 10 to move, the lifting block 10 drives the fixing block 11 to move, so that one end of the fixing block 11 is inserted into the fixing groove. Under the pressure of the fixing block 11, the mounting seat 4 is fixed to the base 5. When it is necessary to disassemble the entire energy-saving water pump, the reverse operation can be used.

[0034] Furthermore, such as Figures 1 to 5 As shown, a sealing plate 16 is movably mounted on one side of the water absorption box 3, a connecting ring 17 is fixedly mounted on the water absorption box 3, an installation ring 19 is fixedly mounted on the outer side of the sealing plate 16, and a rotating ring 20 is rotatably mounted on the outer side of the installation ring 19 via a bearing. The rotating ring 20 is threadedly connected to the connecting ring 17. Multiple limiting rods 21 are fixedly mounted on the installation ring 19, and multiple limiting holes 22 that mate with the limiting rods 21 are provided on the connecting ring 17. A sealing ring 23 is fixedly mounted on one side of the sealing plate 16, and connecting pipes 24 are fixedly mounted on the sealing plate 16 and the water absorption box 3, respectively. A second screw is threaded onto the limiting frame 18. 25. One end of the second screw 25 is rotatably mounted on a fixed plate 26 via a bearing. Two insert rods 27 are fixedly mounted on the fixed plate 26. One end of the two insert rods 27 is inserted into the rotating ring 20. A drive groove 28 is provided on one side of the base 5. One end of the second screw 25 extends into the drive groove 28 and is fixedly mounted on a handle 29. Two slide rods 30 are fixedly mounted on the lower end of the fixed plate 26. One end of the two slide rods 30 extends through the limit frame 18 into the drive groove 28. The slide rods 30 are movably connected to the limit frame 18. An impeller is rotatably mounted inside the water suction box 3. The impeller is connected to the motor 1 via a coupling 2.

[0035] It should be noted that during water pump maintenance, it is necessary to open the sealing plate 16 of its suction box 3 to observe whether the internal impeller is damaged. Currently, water pump assemblies often use a spring-loaded fixing method to secure the sealing plate 16. For example, Chinese utility model patent CN216111317U discloses an energy-saving water pump for a central air conditioning system, which includes a base, a first fixing seat fixedly connected to the upper surface of the base, a mounting plate fixedly connected to the upper surface of the first fixing seat, a first spring fixedly connected inside the mounting plate, a fixing block fixedly connected to the end of the first spring away from the mounting plate, a metal rod fixedly connected to the lower surface of the fixing block, and a bell fixedly connected to the side surface of the metal rod. However, in this device, the sealing plate is fixed by the spring force during use. This fixing method has poor stability. Vibration occurs during the entire operation of the water pump, and the spring deforms with the vibration, making the sealing plate prone to loosening and falling off, thus affecting normal use.

[0036] In this embodiment, the second screw 25 threaded on the limiting frame 18, together with the fixing plate 26 and the insertion rod 27, limits the rotation ring 20. The rotation ring 20, the mounting ring 19 and the connecting ring 17 cooperate with each other to fix the sealing plate 16 and ensure its stability during use.

[0037] Furthermore, when it is necessary to inspect and maintain the impeller inside the water suction box 3, turn the handle 29. The handle 29 drives the second screw 25 to rotate. Since the second screw 25 is threadedly connected to the fixed plate 26, the fixed plate 26 moves downward. The fixed plate 26 drives the two sliding rods 30 to move and limit their movement. At the same time, the fixed plate 26 drives the two insert rods 27 to separate from the rotating ring 20. Rotate the rotating ring 20. The rotating ring 20 rotates around the point where it rotates with the mounting ring 19. Since the rotating ring 20 is threadedly connected to the connecting ring 17, the rotating ring... As the rotating ring 20 rotates, it separates from the connecting ring 17. The connecting ring 17 drives the mounting ring 19 to move. The mounting ring 19 is limited by the limiting rod 21 and the limiting hole 22. When the limiting rod 21 separates from the limiting hole 22, the mounting ring 19 drives the sealing plate 16 to separate from the water suction box 3. The sealing plate 16 can then be removed to inspect and repair the impeller inside the water suction box 3. After the repair is completed, the sealing plate 16 can be installed using the reverse method described above, and the rotating ring 20 can be fixed. The sealing ring 23 seals the space between the sealing plate 16 and the water suction box 3.

[0038] The working process of this utility model is as follows:

[0039] The base 5 is bolted to the location where the water pump needs to be installed. The entire water pump is placed on the base 5, so that the mounting seat 4 near the suction box 3 contacts the limiting bracket 18. The mounting seat 4 has a fixing groove that mates with the fixing block 11, ensuring the fixing groove is perfectly aligned with the fixing block 11. Turning the handle 13 causes the rotating rod 12 to rotate, thus fixing the mounting seat 4 to or separating it from the base 5. When repairing the water pump, the sealing plate 16 needs to be removed. Turning the handle 29 causes the second screw 25 to rotate. Since the second screw 25 is threadedly connected to the fixing plate 26, the fixing plate 26 moves downwards. The fixing plate 26 moves the two sliding rods 30 to limit its movement. Simultaneously, the fixing plate 26 causes the two insert rods 27 to separate from the rotating ring 20. Rotating the rotating ring 20 causes it to rotate around the mounting plate 26. The mounting ring 19 rotates at the rotating connection. Since the rotating ring 20 is threadedly connected to the connecting ring 17, the rotating ring 20 separates from the connecting ring 17 while rotating. The connecting ring 17 drives the mounting ring 19 to move. The mounting ring 19 is limited by the limiting rod 21 and the limiting hole 22. When the limiting rod 21 separates from the limiting hole 22, the mounting ring 19 drives the sealing plate 16 to separate from the water suction box 3, so that the sealing plate 16 can be disassembled. The impeller in the water suction box 3 can be inspected and repaired. After the repair is completed, the sealing plate 16 can be installed by using the reverse method described above, and the rotating ring 20 can be fixed. The sealing ring 23 seals between the sealing plate 16 and the water suction box 3. Using this method to disassemble and install the sealing plate 16, compared with the conventional method of fixing the sealing plate 16 with a spring, makes the sealing plate 16 less likely to loosen during use, ensuring its sealing effect.
