Description

Technical Field

[0001] This application relates to the technical field of water supply equipment, and in particular to a silent variable frequency water supply equipment. Background Technology

[0002] Variable frequency water supply equipment is an advanced water supply system that uses variable frequency speed regulation technology to control the speed of the water pump motor, thereby achieving closed-loop regulation of the water pressure in the user's pipe network. The equipment mainly consists of a pressure tank, a water pump unit, a pressure measuring and stabilizing tank, a pressure sensor, and a variable frequency control cabinet. The equipment can always maintain the pressure gauge pressure equal to the user's setting.

[0003] A search revealed Chinese Patent Publication No. CN221721798U, which discloses a novel silent variable frequency water supply device. The device includes a base plate with a pressure tank fixed to its top. By starting a rotary motor, the device drives a rotating rod at the bottom to rotate. This rotation causes a support frame at the bottom to rotate as well. As the support frame rotates, a brush plate on one side is moved out of its storage slot. When the brush plate moves out of the slot, it compresses a spring to one side, keeping the brush plate in close contact with the inner wall of the pressure tank. This allows the brush plate to scrape away accumulated scale from the inner wall of the pressure tank as it rotates with the support frame, preventing long-term scale buildup. Pulling the handle pulls out a stopper from the discharge pipe, opening the pipe. The inclined design of the discharge pipe facilitates scale removal, solving the problem of difficult-to-clean scale inside the pressure tank.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: The above-mentioned solution uses the rotation of a brush plate to scrape away the scale accumulated on the inner wall of the pressure tank, thereby preventing the scale from accumulating on the inner wall of the pressure tank for a long time. Pulling the handle to pull the plug out of the discharge pipe opens the discharge pipe. Since the discharge pipe is set at an angle, it is conducive to the scale falling out, solving the problem that the scale inside the pressure tank is difficult to clean. However, the noise generated by the water supply equipment during the use of this device will affect the surrounding environment. The inability to reduce the noise generated by the water supply equipment can easily cause irritability, anxiety, and lack of concentration among the staff, thereby affecting work efficiency and potentially causing damage to hearing and other health aspects. Furthermore, continuous vibration will cause greater stress and impact on the connection parts between pipes and between pipes and equipment, accelerating the wear and fatigue damage of components such as pipes, valves, and flanges, reducing the service life of equipment and pipeline systems, and increasing maintenance and replacement costs.

[0015] 2. This utility model incorporates components such as a pressure tank, an elastic clamping plate, a clamping block, and a cover plate.

The cover plate features a double-layer shell design, effectively absorbing mechanical vibration noise and water flow noise generated during motor operation. This achieves the effect of reducing mechanical vibration noise generated during motor operation through the cover plate. Attached Figure Description

[0021] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0022] This application discloses a silent variable frequency water supply device. For example... Figure 1 , Figure 2 , Figure 3 As shown, the device includes a base 1, a soundproof cover 2 fixedly mounted on the upper surface of the base 1, a door 3 hinged to the inner wall of the soundproof cover 2, a connecting frame 4 fixedly connected to the upper surface of the base 1, a pressure tank 5 fixedly connected to the inner wall of the connecting frame 4, and a fixed pipe 7 fixedly connected to the outer surface of the pressure tank 5. The soundproof cover 2 completely encloses the equipment in a relatively independent space. The soundproof cover 2 adopts a multi-layer sound insulation structure, with an inner layer of sound-absorbing material, a middle layer of sound insulation board, and an outer layer of metal protective layer. This design can effectively isolate the noise generated inside the equipment. Ventilation openings and a door 3 are provided on the soundproof cover 2. The ventilation openings are equipped with silencers, and the door 3 is a soundproof door with good sealing performance, ensuring that noise transmission is minimized to the greatest extent without affecting the normal operation and maintenance of the equipment. The connecting frame 4 can support the pressure tank 5, and the fixed pipe 7 serves as the water inlet pipe of the pressure tank 5, facilitating the filling of the pressure tank 5 with water.

[0023] In this embodiment, a pump 6 is fixedly installed on the upper surface of the base 1. The output end of the pump 6 is fixedly connected to the water outlet pipe 18, and the input end of the pump 6 is fixedly connected to the connecting pipe 15. The pump 6 serves as the power source for water supply. It is usually a stainless steel water pump or a silent submersible pump, which has the characteristics of high efficiency, energy saving and low noise. Under the control of the frequency converter control cabinet, the operating status is adjusted according to the water demand. The connection between the pump 6 and the connecting pipe 15 enables the pump 6 to draw water from the pressure tank 5 through the connecting pipe 15.

[0024] Please see Figure 4 Two damping rods 19 are fixedly installed on the outer surface of the base 1. Each damping rod 19 has a connector 20 fixedly connected to its output end. Each connector 20 has a support rod 21 rotatably connected to its inner wall. Each support rod 21 has a fixed head 22 rotatably connected to its end away from the corresponding connector 20. The damping rods 19 are designed to provide buffering. During this process, the support rod 21 will rotate around the corresponding connector 20 and fixed head 22.

[0025] In a preferred embodiment, a fixing block 25 is fixedly connected to the outer surface of each fixing head 22, and two connecting blocks 23 are provided between the two fixing heads 22. Each connecting block 23 has a T-shaped groove 24 inside, and the inner wall of each T-shaped groove 24 is slidably connected to the corresponding fixing block 25. A connecting tube 15 is provided between the two fixing heads 22, and the inner wall of each fixing head 22 is engaged with the connecting tube 15. By vertically inserting the connecting block 23 along the overlapping fixing blocks 25, the T-shaped groove 24 will be inserted into the corresponding fixing block 25, so that the two connecting blocks 23 can be quickly fixed, and the connecting tube 15 can be clamped by the fixing head 22.

[0026] Looking back Figure 2The outer surface of the pressure tank 5 is fixedly connected with a locking block 10. The pressure tank 5 is provided with a cover plate 8. The outer surface of the cover plate 8 is fixedly connected with an elastic locking plate 9. The outer surface of each elastic locking plate 9 is engaged with the corresponding locking block 10. By installing the cover plate 8 on the pressure tank 5, the elastic locking plate 9 will be vertically inserted along the corresponding locking block 10 until the elastic locking plate 9 is engaged with the corresponding locking block 10, so that the cover plate 8 can be quickly fixed.

[0027] like Figure 3 As shown, a support plate 11 is fixedly connected to the inner wall of the pressure tank 5. The output end of the pressure tank 5 is fixedly connected to the connecting pipe 15. A waste pipe 17 is fixedly connected to the inner wall of the connecting pipe 15. A filter plate 16 is provided below the waste pipe 17. The outer surface of the filter plate 16 is fixedly connected to the connecting pipe 15. The waste filtered by the filter plate 16 can be discharged through the waste pipe 17. The filter plate 16 can filter the water flow in the pressure tank 5.

[0028] In this embodiment, a motor 12 is fixedly installed on the upper surface of the support plate 11. A connecting rod 13 is fixedly connected to the output end of the motor 12. A scraper 14 is fixedly connected to the outer surface of the connecting rod 13. By starting the motor 12, the motor 12 will drive the connecting rod 13 to rotate. The rotation of the connecting rod 13 will drive the scraper 14 to remove impurities attached to the inner wall of the pressure tank 5.

[0029] The implementation principle of a silent variable frequency water supply device according to an embodiment of this application is as follows: The cover plate 8 is installed along the pressure tank 5. During this process, the cover plate 8 can be quickly installed through the interlocking of the elastic clamping plate 9 and the corresponding clamping block 10. The soundproof enclosure 2 completely encloses the equipment in a relatively independent space. The soundproof enclosure 2 adopts a multi-layer sound insulation structure, with an inner layer of sound-absorbing material, a middle layer of sound insulation board, and an outer layer of metal protective layer. This design can effectively isolate the noise generated inside the equipment. Furthermore, ventilation openings and a door 3 are provided on the soundproof enclosure 2. Silencers are installed at the ventilation openings, and the door 3 is sealed. A high-performance soundproof door ensures that noise transmission is minimized without affecting the normal operation and maintenance of the equipment. The pressure tank 5 can be supported by the connecting frame 4. Therefore, the noise spread can be reduced by the soundproof cover 2 and the cover plate 8. Then, the damping rod 19 is installed on the base 1 and the two fixing heads 22 are quickly installed by the connecting block 23. During this process, the water will vibrate as it flows through the connecting pipe 15. At this time, the damping rod 19 and the support rod 21 can reduce the vibration and noise of the connecting pipe 15.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
