Description

Technical Field

[0001] This utility model relates to the field of water pump connector connection, and more specifically, to a water pump connector connection device. Background Technology

[0002] A water pump is a machine that transports or pressurizes liquids. Existing water pumps are generally high-efficiency and energy-saving pumps, which effectively improve the working efficiency of the water pump and save energy.

[0003] In existing technology, the pump body will vibrate during normal operation. In order to prevent the vibration of the pump body from causing resonance effect in the entire system or rigid damage to the pipeline network, a rubber flexible joint is installed at the interface of the pump body. The flexible connection at the interface avoids the vibration of the pump body from affecting the connection with the connecting pipe.

[0004] However, through the flexible rubber connection, the impact force inside the pump body will act directly on the inner surface of the rubber, which may cause the rubber to wear and crack over time. After the rubber joint is damaged, the conveying system needs to be shut down for repair, which not only increases the direct losses, but also the indirect losses caused by the shutdown.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] The purpose of this utility model is to provide a water pump connector connection device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A water pump connector connection device includes a pump body and a connecting pipe. The surface of the pump body is provided with a water outlet end, and the end face of the connecting pipe is provided with a connecting end. Both the surface of the water outlet end and the connecting end are provided with sealing grooves. Both the water outlet end and the connecting end are fixedly installed with mounting plates by limiting bolts.

[0009] A limiting plate is mounted on the surface of the mounting plate by positioning bolts. A sealing plate is provided on the end face of the limiting plate. A rubber joint is provided on the surface of the sealing plate. A guide plate is provided on the inner surface of the rubber joint.

[0010] Furthermore, a sealing gasket is provided on the surface of the sealing groove, and a protrusion is provided on the side of the mounting plate to insert into the sealing groove.

[0011] Furthermore, a positioning groove is provided on the surface of the mounting plate, and a rubber pad is provided on the surface of the positioning groove, into which the sealing plate is inserted.

[0012] Furthermore, the rubber joint is provided with metal wires, and the end face of the rubber joint is fixedly connected to the surface of the sealing plate.

[0013] Furthermore, the guide plate is provided in several groups, and the several groups of guide plates are evenly laid on the inner surface of the rubber joint, with elastic plates provided between the several groups of guide plates.

[0014] Furthermore, an auxiliary plate is provided on the inner surface of the rubber joint near the water outlet end, and a wave spring is provided on the inner side of the auxiliary plate. One end of the wave spring is fixedly connected to the inner side of the auxiliary plate, and the other end of the wave spring is fixedly connected to the inner surface of the rubber joint.

[0015] Compared with the prior art, the present invention has the following advantages: The structure of the present invention first fixes the sealing plate to the side of the mounting plate with positioning bolts, then uses limiting bolts to fix one set of mounting plates to the end face of the connecting pipe, and then fixes another set of mounting plates to the outlet end of the pump body. Thus, the rubber joint set between the two sets of mounting plates facilitates the flow of liquid discharged from the pump body into the connecting pipe. In addition, the guide plate set on the inner surface of the rubber joint guides the impact of the water flow, avoiding the impact force of the water flow from directly acting on the inner surface of the rubber joint, which would cause wear and cracking of the inner surface of the rubber joint. The setting of the guide plate also helps to improve the service life of the rubber joint. Attached Figure Description

[0026] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0027] Please see Figure 1-7 According to an embodiment of the present invention, a water pump connector connection device includes a pump body 1 and a connecting pipe 2. The pump body 1 has an outlet end 3 on its surface, and the connecting pipe 2 has a connecting end 4 on its end face. Both the outlet end 3 and the connecting end 4 have sealing grooves 5 on their surfaces. Both the outlet end 3 and the connecting end 4 are fixedly mounted with mounting plates 7 by limiting bolts 6. A limiting plate 9 is mounted on the surface of the mounting plate 7 by positioning bolts 8. A sealing plate 10 is provided on the end face of the limiting plate 9. A rubber joint 11 is provided on the surface of the sealing plate 10, and a guide plate 12 is provided on the inner surface of the rubber joint 11. First, the sealing plate 10 is fixedly connected to the surface of the mounting plate 7 by the positioning bolts 8 to facilitate subsequent use of the rubber joint 11. Then, the mounting plate 7 is fixedly connected to the connecting end 4 of the connecting pipe 2 and the outlet end 3 of the pump body 1 by the limiting bolts 6, facilitating the connection of the connecting pipe 2 and the pump body 1 via the rubber joint 11. The elasticity of the rubber joint 11 ensures that the vibration generated during the operation of the pump body 1 will not affect the normal use of the connecting pipe 2.

[0028] Please see Figure 6 and Figure 7 As shown, a sealing gasket 13 is provided on the surface of the sealing groove 5, and a protrusion is provided on the side of the mounting plate 7 to be inserted into the sealing groove 5. A positioning groove 14 is provided on the surface of the mounting plate 7, and a rubber gasket 15 is provided on the surface of the positioning groove 14. The sealing plate 10 is inserted into the positioning groove 14. First, the sealing gasket 13 is squeezed by inserting the mounting plate 7 into the sealing groove 5, and then the rubber gasket 15 is squeezed by inserting the sealing plate 10 into the positioning groove 14, thereby improving the sealing effect between the mounting plate 7 and the connecting end 4 and between the sealing plate 10 and the mounting plate 7.

[0029] Please see Figure 4 and Figure 5As shown, a metal wire 16 is provided inside the rubber joint 11, and the end face of the rubber joint 11 is fixedly connected to the surface of the sealing plate 10. By providing a metal wire 16 inside the rubber joint 11, and providing multiple sets of metal wires 16, which are evenly laid inside the rubber joint 11, the overall tensile and compressive strength of the rubber joint 11 is increased, which facilitates the long-term use of the rubber joint 11.

[0030] Please see Figures 5-7 As shown, the guide plate 12 is provided in several groups, which are evenly laid on the inner surface of the rubber joint 11. Elastic plates 17 are provided between the groups of guide plates 12. An auxiliary plate 18 is provided on the inner surface of the end of the rubber joint 11 near the water outlet 3. A wave spring 19 is provided on the inner side of the auxiliary plate 18. One end of the wave spring 19 is fixedly connected to the inner side of the auxiliary plate 18, and the other end of the wave spring 19 is fixedly connected to the inner surface of the rubber joint 11. The tilt angle of the guide plate 12 is set to facilitate the guidance of water flow and avoid the impact force of the water flow from directly acting on the inner surface of the rubber joint 11. In addition, the connection of the elastic plate 17 facilitates the stability of the guide plate 12 during long-term use and provides a supporting effect. In addition, the elasticity of the wave spring 19 itself supports the auxiliary plate 18. First, the auxiliary plate 18 provides initial guidance of water flow, and then the elasticity of the wave spring 19 facilitates the automatic reset of the auxiliary plate 18 and reduces the impact force received.

[0031] Through the above-described scheme of this utility model, the sealing plate 10 is first fixed to the side of the mounting plate 7 by the positioning bolt 8, and then a set of mounting plates 7 is fixedly connected to the end face of the connecting pipe 2 by the limiting bolt 6. Then, another set of mounting plates 7 is fixedly connected to the water outlet 3 of the pump body 1. Thus, the liquid discharged from the pump body 1 flows into the connecting pipe 2 through the rubber joint 11 set between the two sets of mounting plates 7. In addition, a guide plate 12 is set on the inner surface of the rubber joint 11. The guide plate 12 guides the impact of the water flow and avoids the impact force of the water flow directly acting on the inner surface of the rubber joint 11, which would cause wear and cracking of the inner surface of the rubber joint 11. The setting of the guide plate 12 also helps to improve the service life of the rubber joint 11.
