Description

Technical Field

[0001] This utility model belongs to the field of water supply, specifically relating to a shock-absorbing and noise-reducing secondary water supply device. Background Technology

[0002] In the water supply and drainage industry, secondary water supply equipment is frequently used. This equipment typically consists of an inlet assembly pipe, a distribution assembly pipe, a booster pump set (composed of one or more identical or different pumps), a supply assembly pipe, and a control cabinet. The secondary water supply equipment is fixed on a horizontal base for easy operation. After connecting to the main pipeline, tap water flows through the inlet assembly pipe and the distribution assembly pipe into the assembled pumps. After being pressurized by the pumps, the water is output to the supply assembly pipe, and then from there it is transported to the water pipes for use by users in high-altitude areas.

[0003] The upper pump of the booster pump set in the secondary water supply equipment vibrates during operation, causing the entire secondary water supply equipment to vibrate slightly. Since the secondary water supply equipment is fixed to a concrete or brick base, the low-frequency vibrations generated by the equipment spread through the base and the frame, producing noise. This is particularly problematic in certain situations, such as when the equipment is placed in a basement near a shear wall. Because the shear wall is directly connected to the main building structure, the low-frequency vibration noise is transmitted through the base to the shear wall, and then from the shear wall to the main building structure, resulting in low-frequency noise pollution that is difficult to trace. Current solutions to this problem involve laying vibration-damping pads between the base and the frame to absorb some vibration. However, this method has limitations: thin pads have poor vibration filtering; excessively thick pads lack sufficient support, resulting in instability and safety hazards. Furthermore, if bolts, connecting rods, or other connecting components are used between the base and the frame, vibrations can still easily be transmitted to the base through these contact parts, and then spread from the base to the surrounding area, generating noise. Utility Model Content

[0004] The purpose of this invention is to overcome the low-frequency noise problem of existing secondary water supply equipment and to provide a secondary water supply equipment that can effectively reduce vibration and reduce the propagation of low-frequency vibrations.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a shock-absorbing and silent secondary water supply device, including a secondary water supply device, a base, an inflatable shock-absorbing pad with an air nozzle, and a limiting frame. The secondary water supply device is fixed on the base. The base is provided with side plates and a top plate. The side plates and the top plate form a square shell covering the lower part of the secondary water supply device. The inflatable shock-absorbing pad is distributed on the bottom of the base, the four side plates, and the top plate. The limiting frame limits the inflatable shock-absorbing pad on the side plates and the top plate. The inflatable shock-absorbing pad is suspended and positioned to keep the secondary water supply device in place.

[0006] Optionally, the inflatable shock absorber has multiple support plates inside, which divide the interior of the inflatable shock absorber into multiple small chambers. The support plates have ventilation holes, and the small chambers are connected to each other through the ventilation holes.

[0007] Optionally, the inflatable shock absorber mainly consists of inflatable shock absorber I, inflatable shock absorber II, and inflatable shock absorber III, which are respectively distributed on the bottom of the base, the four side plates, and the top plate.

[0008] Optionally, the inflatable shock-absorbing pad includes a main body and side plates distributed on all four sides. The main body is located at the bottom of the base, and the side plates cover the four side plates and the top plate.

[0009] Optionally, the limiting frame mainly consists of a fixed plate, a vertical plate, and a horizontal plate, with a cross-section of "Z". The vertical plate has an inflatable shock-absorbing pad on its horizontal limiting side plate, and the horizontal plate has an inflatable shock-absorbing pad on its vertical limiting top plate. Reinforcing ribs are provided between the fixed plate and the vertical plate.

[0010] The method of using this utility model is as follows: A brick-concrete base is determined in the basement or equipment floor of a building for placing the equipment. The placement position of the secondary water supply equipment and the fixing position of the limiting frame are planned on the base. When planning the position of the limiting frame, the water inlet assembly pipe of the secondary water supply equipment extending from the side plate is avoided. Next, an inflatable shock-absorbing pad is laid at the planned placement position of the secondary water supply equipment on the base, and the secondary water supply equipment is placed on it. At the fixing position of the limiting frame on the base, the limiting frame is fixed to the base with screws. The limiting frames are distributed around the secondary water supply equipment. Then, slightly inflated shock-absorbing pads are placed between the limiting frames and the sides and top plate. Finally, the inflatable shock-absorbing pads are inflated to suspend and position the secondary water supply equipment.

[0011] The principle of this invention is as follows: The inflatable shock-absorbing pad under the base is inflated, lifting the secondary water supply equipment and suspending it in an unstable state. Therefore, stability is achieved around the secondary water supply equipment through a side plate fixed to the base, a limiting frame fixed to the base, and an inflatable shock-absorbing pad placed between the side plate and the limiting frame. When the inflatable shock-absorbing pad is inflated, it surrounds the secondary water supply equipment for horizontal positioning. Vertical stability is achieved through a limiting frame fixed to the base and an inflatable shock-absorbing pad placed between the top plate and the limiting frame. When the inflatable shock-absorbing pad is inflated, the inflatable shock-absorbing pad on the top plate and the inflatable shock-absorbing pad under the base clamp the secondary water supply equipment for vertical positioning. The above method is used to keep the secondary water supply equipment in a stable suspended state. The air-filled shock-absorbing pads isolate the secondary water supply equipment from direct contact with the base and the limiting frame. When the booster pump of the secondary water supply equipment is running, the low-frequency vibration generated by it will be absorbed by the air-filled shock-absorbing pads, and the propagation of low-frequency vibration will be effectively suppressed, thereby achieving the effect of vibration reduction and noise reduction.

[0012] Compared with the prior art, the beneficial effects of this utility model are: this utility model can effectively absorb vibration, suppress the propagation of low-frequency vibration, and has a better shock absorption and noise reduction effect. Attached Figure Description

The base is a rectangular platform welded from steel. The inflatable shock-absorbing pad is made of high-molecular elastic materials such as rubber or silicone and is hollow inside. The air nozzle is glued to the outside. The limiting frame is a metal frame. The secondary water supply device is fixed to the base by screws, welding, or other means. The base is provided with a side plate 5 and a top plate 6. The side and top plates are made of high-strength plastic or metal sheets, forming a square shell covering the lower part of the secondary water supply equipment. The side plates are fixed to the base by screws, welding, etc. The inner side of the side plates has downward-sloping support ribs to withstand external pressure. The top plate consists of multiple small plates, some with notches for equipment extension. The top plate rests on the side plates through grooves on both sides at the bottom. Alternatively, the base can be welded into a cuboid structure using square tubing, with the side and top plates embedded within the frame. The outer sides of the side and top plates are flush with the outer sides of the frame, forming a neat plane. Inflatable shock-absorbing pads are distributed at the bottom of the base, on the four side plates, and on the top plate. Four limiting frames are fixed around the secondary water supply equipment, each with a certain length but not exceeding the length of the side plates. The limiting frames limit the inflatable shock-absorbing pads on the side and top plates, allowing the inflatable shock-absorbing pads to inflate and suspend the secondary water supply equipment for positioning.

[0018] To improve the pressure resistance of the inflatable shock absorber, an internal structure for the inflatable shock absorber is provided. The inflatable shock absorber has multiple vertical support plates 31 arranged in a crisscross pattern. The two ends of the support plates are fixed to the inner wall of the inflatable shock absorber. The support plates divide the interior of the inflatable shock absorber into multiple small chambers 32. The support plates are provided with ventilation holes 33, and the small chambers are connected to each other through the ventilation holes.

[0019] For ease of use, the inflatable shock absorber is in the form of a flat pad, which can consist of a whole with different folds, or multiple pads can be used in combination. For multiple pads used in combination, the inflatable shock absorber mainly consists of inflatable shock absorber I, inflatable shock absorber II, and inflatable shock absorber III, which are respectively distributed on the bottom of the base, the four side panels, and the top plate. For a single unit, the inflatable shock absorber includes a main body and side panels distributed on all four sides. The main body is located at the bottom of the base, and the side panels cover the four side panels and the top plate.

[0020] For ease of understanding, a limiting frame structure is provided. The limiting frame is mainly composed of a fixed plate 41, a vertical plate 42 and a horizontal plate 43. Its cross-section is "Z". There are inflatable shock-absorbing pads on the horizontal limiting side plate of the vertical plate and inflatable shock-absorbing pads on the vertical limiting top plate of the horizontal plate. An oblique reinforcing rib 7 is provided between the fixed plate and the vertical plate.
