Description

Technical Field

[0001] This utility model belongs to the field of pump cover technology, specifically relating to a low-noise pump cover. Background Technology

[0002] A water pump is a mechanical device that converts the mechanical energy of a prime mover into the energy of a liquid. It is widely used in agricultural irrigation, industrial drainage, and domestic water supply. The pump cover is an important component of a water pump. It is usually installed on the top of the pump body to seal the pump chamber, prevent fluid leakage, and ensure the normal operation of the pump.

[0003] For example, Chinese Patent No. CN216950826 U discloses a noise-reducing waterproof pump cover for a water pump. This utility model, by setting a buffer component, utilizes the elasticity of the metal sheet and its arc-shaped surface to effectively reduce the impact force of water flow on the pump cover body, thereby reducing the probability of the pump cover body generating high-frequency vibration due to excessive water flow impact, thus achieving a noise reduction effect. At the same time, by setting buffer cotton between the metal sheet and the pump cover body, the overall buffering capacity of the buffer component can be improved, and sound can be isolated to a certain extent, thereby achieving a sound insulation effect.

[0004] However, the aforementioned noise-reducing waterproof pump cover for water pumps has shortcomings in use: the buffer cotton set between the metal sheet and the pump cover body, and the sound insulation cotton between the sealing ring and the corrugated connecting groove, are not easy to disassemble and replace, and the operation is relatively cumbersome; now, a low-noise pump cover is provided to alleviate the above-mentioned problems. Summary of the Invention

[0005] This utility model achieves the purpose of quickly replacing sound insulation panels by using a combination of a positioning post, a first bolt, a mounting block, and a locking block to install the positioning post, the first bolt, and the mounting block into the positioning circular groove, the first threaded hole, and the mounting groove, respectively.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A low-noise pump cover includes a pump cover body and a sound insulation plate. The sound insulation plate has a sound insulation collar on one side near the pump cover body. A mounting opening is formed on one side of the pump cover body, and a positioning groove is formed inside the mounting opening. A positioning post is formed on one side of the sound insulation collar. A first threaded hole is formed on one side of the pump cover body near the top of the mounting opening. A third threaded hole is formed on the surface of the sound insulation plate at the first threaded hole. A first bolt is connected to the first threaded hole and the third threaded hole.

[0013] Compared with the prior art, the gain effect of this utility model is as follows:

[0014] 1. By setting up a structure including a positioning groove, positioning pins, a first bolt, a mounting block, a locking block, a moving plate, a spring, and a connecting plate, the connecting plate and the moving plate are moved in opposite directions by the lever, and the moving plate moves the locking block. At the same time, the spring is compressed and deformed. When the locking block is fully inserted into the mounting block, the mounting block is placed into the mounting groove. Simultaneously, multiple positioning pins on one side of the sound insulation collar are inserted into the positioning groove of the pump cover body. Then, the lever force on the lever is removed, and under the action of the spring's return force, one end of the locking block is fully inserted into the locking groove.

[0032] Please see Figure 1-7 Each movable plate 20 has a connecting plate 22 fixedly installed at its upper end. Each cavity has a rectangular groove 29 on its inner top surface. The surface of the sound insulation plate 4 has a through groove 25 at the rectangular groove 29. The top of the connecting plate 22 passes through the rectangular groove 29 and the through groove 25 in sequence and is fixedly connected to a lever 23. The connecting plate 22 is slidably connected to the rectangular groove 29 and the through groove 25 respectively. Each connecting plate 22 has a guide rod 24 slidably installed in it. The guide rod 24 is horizontally installed above the spring 21. The two ends of the guide rod 24 are fixedly connected to the inner side wall of the cavity respectively. Through the guide rod 24, the connecting plate 22 is limited, so that the connecting plate 22 can move stably.

[0033] Please see Figure 1-7The movable plate 20 is fixedly provided with mirror-distributed stabilizing blocks 26 on its exterior. Stabilizing rods 27 are slidably inserted into each stabilizing block 26. The two ends of the stabilizing blocks 26 are fixedly connected to the inner wall of the mounting block 17.

An adsorption plate 10 is installed on one side of the protective net 9, and a sound-absorbing cotton 11 is installed on the side of the adsorption plate 10 away from the protective net 9. The outer surfaces of the adsorption plate 10 and the sound-absorbing cotton 11 are fixedly connected to the inner wall of the sound insulation panel 4. In this way, the noise generated by the pump body during operation can be absorbed and reduced by the sound-absorbing cotton 11, and the adsorption plate 10 can effectively absorb dust in the air, which can effectively reduce the probability of dust in the air damaging the working components in the pump body, improve the service life of the pump, and thus improve its practicality in actual use.

[0036] Working principle: When this utility model is in use, when noise reduction of the water pump is required, the toggle block 23 is moved in the opposite direction through the connecting plate 22, which drives the moving plate 20 to move in the opposite direction. The moving plate 20 drives the locking block 18 to move in the opposite direction. At the same time, the spring 21 is compressed and deformed. When the locking block 18 is fully inserted into the mounting block 17, the mounting block 17 is placed into the mounting groove 16. At the same time, multiple positioning pins 6 on one side of the sound insulation ring 5 are inserted into the positioning circular groove 3 of the pump cover body 1, so that the sound insulation ring 5 is placed in the mounting circular opening 2 on the pump cover body 1. Then, the toggle force on the toggle block 23 is removed. Under the action of the spring 21's return force, the moving plate 20 drives the locking block 18 to move in the opposite direction until one end of the locking block 18 is fully inserted into the locking groove 19. Then, the first bolt 7 is installed into the first threaded hole 8, completing the installation between the sound insulation plate 4 and the pump cover body 1.
