Description

Technical Field

[0001] This application relates to the field of water supply equipment technology, specifically a low-noise, negative-pressure-free water supply system. Background Technology

[0002] In recent years, with rapid economic development, high-rise buildings have sprung up everywhere, standing tall before people's eyes. However, due to the fact that the pressure of the municipal pipe network can only reach about 0.2MPa, the water pressure and water quality problems of high-rise users have been troubling the designers of water supply companies. With the development of technology, the emergence of negative pressure water supply systems has solved the above problems. However, the water supply system generates a lot of noise during operation. The main reason is that the water pumps in the water supply system will generate a certain amount of vibration during operation, which leads to noise. Moreover, as the power of the water pumps increases, the vibration of the water pumps also increases, and the noise also increases, affecting the daily life of nearby residents. Utility Model Content

A water storage tank is provided on the support plate. The water storage tank is connected to the water pumping mechanism and the pressurizing mechanism.

[0004] The buffer mechanism includes a buffer seat, a buffer slide, a buffer spring, and a buffer platform. The buffer seat and the buffer platform are mounted on the base. The buffer slide is sleeved on the buffer seat. The buffer spring is located between the buffer slide and the buffer seat. The buffer platform is located in the middle of the buffer seat and is mounted on the buffer seat.

[0005] Guide rails are installed on the inclined surfaces on both sides of the buffer platform, and buffer blocks are slidably installed on the guide rails. Connecting rods are rotatably installed on both sides of the buffer blocks, and the other end of the connecting rods is rotatably installed on the top surface inside the buffer sliding shell.

[0006] The buffer platform is in the shape of an inverted trapezoid, the buffer block is in the shape of a concave "U", the guide rail is in the shape of a "T", and the narrow side of the guide rail is installed on the two sides of the buffer platform.

[0007] The side of the buffer platform is rough, the wide side of the guide rail is smooth, the A side of the buffer block is rough, and the B side of the buffer block is smooth.

[0008] When the buffer block moves downward along the guide rail, surface B of the buffer block contacts the wide side of the guide rail; when the buffer block moves upward along the guide rail, surface A of the buffer block contacts the side of the buffer platform.

[0009] A connecting pipe is installed on the left side of the water storage tank, and the connecting pipe is connected to the inside of the water storage tank. A water inlet pipe is provided on the water storage tank, and the water inlet pipe is connected to the inside of the water storage tank. A pressure gauge is installed on the side of the water inlet pipe.

[0010] The water pumping mechanism consists of an inlet pump pipe, a pump chamber, an outlet pump pipe, and a water pump. The pump chamber is mounted on the buffer sliding shell, and the water pump is mounted on the pump chamber. The inlet pump pipe is mounted on the right side of the pump chamber, and the outlet pump pipe is mounted on the left side of the pump chamber. A valve is provided between the inlet pump pipe and the pump chamber. The inlet pump pipe is connected to the connecting pipe. The other end of the outlet pump pipe is connected to a guide pipe, which is connected to the guide pipe. A drain pipe is connected to one side of the guide pipe, which is connected to the drain pipe.

[0012] The present application has the following beneficial effects: a buffer mechanism is provided below the pump mechanism, which absorbs the vibration generated during the operation of the pump mechanism through the buffer spring, and slows down the rebound speed of the buffer spring after absorbing the vibration through the friction between the buffer block and the side of the buffer platform, thereby playing a certain damping role and effectively reducing the noise generated during the operation of the water supply equipment.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] A low-noise, negative-pressure-free water supply system, based on Figure 1 and Figure 2 As shown, the device includes a base 8, on the upper surface of which a support plate 9, a buffer mechanism 3, and a pressurizing mechanism 2 are provided. The buffer mechanism 2 and the pressurizing mechanism 2 are installed on the left side of the support plate 9. A water pumping mechanism 4 is provided on the buffer mechanism 2. A water storage tank 1 is provided on the support plate 9. The water storage tank 1 is connected to the water pumping mechanism 4 and the pressurizing mechanism 2.

[0023] according to Figure 2 and Figure 3As shown, the buffer mechanism 3 includes a buffer seat 38, a buffer sliding shell 37, a buffer spring 34, and a buffer platform 31. The buffer seat 38 and the buffer platform 31 are mounted on the base 8. The buffer sliding shell 37 is sleeved on the buffer seat 38. The buffer spring 34 is located between the buffer sliding shell 37 and the buffer seat 38. The buffer platform 31 is located in the middle of the buffer seat 38 and is mounted on the buffer seat 38. The buffer sliding shell 37 is sleeved inside the buffer seat 38, fixing the movement direction of the buffer sliding shell 37 so that the buffer sliding shell 37 can only move up and down in contact with the buffer seat 38. A cylindrical locking block 35 is respectively installed on the inner top surface of the buffer sliding shell 37 and the inner bottom surface of the buffer seat 38. The buffer spring 34 is sleeved on the cylindrical locking block 35. The cylindrical locking block 35 serves to fix the buffer spring 34 and prevent the buffer spring 34 from shifting.

[0024] according to Figure 3 As shown, guide rails 33 are installed on the inclined surfaces of the buffer platform 31. Buffer blocks 32 are slidably installed on the guide rails 33. Connecting rods 36 are rotatably installed on both sides of the buffer blocks 32. The other end of the connecting rods 36 is rotatably installed on the top surface inside the buffer sliding shell 37. When the buffer sliding shell 37 moves downward, the connecting rods 36 rotate and drive the buffer blocks 32 to slide obliquely downward along the guide rails 33. When the buffer spring 34 absorbs energy and rebounds, driving the buffer sliding shell 37 to move upward, the connecting rods 36 are pulled upward and rotated. The connecting rods 36 pull the buffer blocks 32 to slide upward along the guide rails 33. A limit block is also provided at the upper end of the guide rails 33 to prevent the buffer blocks 32 from sliding off the guide rails 33 when moving upward.

[0025] according to Figure 3 and Figure 4 As shown, the buffer platform 31 is in the shape of an inverted trapezoid, the buffer block 32 is in the shape of a concave U, and the guide rail 33 is in the shape of a T. The narrow side of the guide rail 33 is installed on the two sides of the buffer platform 31.

[0026] according to Figure 4 As shown, the side of the buffer platform 31 is a rough surface, the wide side of the guide rail 33 is a smooth surface, the A surface of the buffer block 32 is a rough surface, and the B surface of the buffer block 32 is a smooth surface.

[0027] according to Figure 3As shown, when the buffer block 32 moves downward along the guide rail 33, the B-side of the buffer block 32 contacts the wide side of the guide rail 33; when the buffer block 32 moves upward along the guide rail 33, the A-side of the buffer block 32 contacts the side of the buffer platform 31. When the buffer block 32 moves downward, the contact area is small and the contact surface is smooth, resulting in low friction; when the buffer block 32 moves upward, the contact area is large and the contact surface becomes rough, increasing the friction on the buffer block 32 and slowing down the rebound speed of the buffer spring 34.

[0028] according to Figure 2 As shown, a connecting pipe 6 is installed on the left side of the water storage tank 1, and the connecting pipe 6 is connected to the interior of the water storage tank 1. A water inlet pipe 5 is provided on the water storage tank 1, and the water inlet pipe 5 is connected to the interior of the water storage tank 1. A pressure gauge is installed on the side of the water inlet pipe 5.

[0029] according to Figure 3 and Figure 5 As shown, the water pumping mechanism 4 consists of an inlet pump pipe 41, a pump chamber 45, an outlet pump pipe 43, and a water pump 44. The pump chamber 45 is mounted on the buffer sliding shell 37, and the water pump 44 is mounted on the pump chamber 45. The inlet pump pipe 41 is mounted on the right side of the pump chamber 45, and the outlet pump pipe 43 is mounted on the left side of the pump chamber 45. A valve 42 is provided between the inlet pump pipe 41 and the pump chamber 45. The inlet pump pipe 41 is connected to the connecting pipe 6. The other end of the outlet pump pipe 43 is connected to a guide pipe 10, which is connected to the guide pipe 10. A drain pipe 7 is connected to one side of the guide pipe 10, which is connected to the drain pipe 7.

[0030] according to Figure 1 and Figure 2 As shown, the pressurizing mechanism 2 includes a pressurizer 21, which is mounted on the base 8. Pressurizing pipes are installed on the left and right sides of the pressurizer 21, and the pressurizing pipes are connected to the connecting pipe 6 and the water guide pipe 10 respectively.

[0031] Working principle: The staff seals and connects the two external pipes to the inlet pipe 5 and the drain pipe 7 respectively. External tap water flows into the water storage tank 1 through the inlet pipe 5. The inside of the water storage tank 1 is connected to the connecting pipe 6. Tap water flows from the inside of the water storage tank 1 into the connecting pipe 6. The connecting pipe 6 is connected to the inlet pump pipe 41. Tap water enters the pump chamber 45 through the inlet pump pipe 41. The water pump 44 operates and pumps the tap water from the pump chamber 45 into the guide pipe 10 through the outlet pipe 43. The guide pipe 10 is connected to the drain pipe 7. Tap water is discharged from the guide pipe 10 through the drain pipe 7. The guide pipe 10 and the connecting pipe 6 are connected to the pressure booster 21 respectively. The pressure booster 21 pressurizes both the guide pipe 10 and the connecting pipe 6 at the same time, ensuring that the water supply equipment has sufficient water pressure to provide to residents when the municipal water pressure is insufficient.

[0032] During operation, the water pump 44 generates vibrations. Due to these vibrations, the buffer housing 37 moves downwards, compressing the buffer spring 34. The compressed buffer spring 34 absorbs the vibrations. The downward movement of the buffer housing 37 within the buffer seat 38 drives the connecting rod 36 to move downwards and rotate. The connecting rod 36 pushes the buffer block 32 downwards. Combined with the weight of the buffer block 32, its B-side contacts and slides against the wide side of the guide rail 33, resulting in low friction. After being compressed, the buffer spring 34 rebounds upwards, causing the buffer housing 37 to move upwards. This upward movement of the buffer housing 37 drives the connecting rod 36 to move upwards and rotate. The connecting rod 36 pulls the buffer block 32 upwards. The A-side of the buffer block 32 contacts and slides against the side of the buffer platform 31, resulting in high friction. This slows down the upward sliding speed of the buffer block 32, which in turn slows down the upward movement of the buffer housing 37. Consequently, the upward rebound speed of the buffer spring 34 also slows down. The vibrations generated by the water pump 44 are absorbed, reducing the noise generated by the water supply system during operation.
