Description

Technical Field

[0001] The invention relates to the technical field of non-negative pressure pipe network water supply, and in particular to non-negative pressure pipe network pressurized and steady-flow water supply equipment with a silencing function. Background Art

[0002] Negative pressure pipe network booster equipment refers to a new type of equipment that can be directly connected to the tap water pipe, uses expansion joints and vacuum compensation systems, and adopts new microcomputer-controlled frequency conversion technology. It can make full use of the existing water pressure in the pipe network, so that the motor pump works in a variable speed operation mode, and only replenishes the pressure of the difference between the inlet water pressure and the required pressure. When the low-peak tap water pressure can meet the user's water requirements, it does not work, does not consume electricity, and is directly supplied by tap water, with significant energy-saving effects.

[0003] Existing negative pressure pipe network boosting equipment is mostly installed in human living and working areas, and multiple water pumps are installed inside the negative pressure pipe network boosting equipment. During the operation of the negative pressure pipe network boosting equipment, multiple water pumps work at the same time and generate noise, which has a certain impact on the living conditions of nearby humans. Secondly, negative pressure pipe network boosting equipment is mostly installed outdoors, and the water pump is directly exposed to the external environment. The external temperature will have a greater impact on the performance of the water pump. Finally, during the use of the existing negative pressure pipe network boosting equipment, the equipment is often impacted by water hammer caused by sudden water flow, which in turn has a certain impact on the service life of the equipment. Summary of the invention

[0004] The purpose of the present invention is to provide a non-negative pressure pipe network pressurized and steady-flow water supply equipment with a silencing function to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a non-negative pressure pipe network pressurized and steady-flow water supply equipment with a silencing function, comprising an expansion joint, a water pump and a steady-flow pipe, a pipe is connected to the bottom of the steady-flow pipe, and the two ends of the pipe are respectively connected to the water supply pipe and the residential water pipe through the expansion joint, the steady-flow pipe is annular, the middle part of the steady-flow pipe is connected to the boosting pipe through the water pump, and a noise reduction component is arranged in the middle part of the steady-flow pipe, and the noise reduction component is used to absorb the noise generated by the water pump and the steady-flow pipe during operation;

[0006] Shock-absorbing components are provided at both ends of the flow-stabilizing tube, and the shock-absorbing components include a guide component, an energy-absorbing component and an adjustment component. The guide component is used to control the movement direction of the flow-stabilizing tube, the energy-absorbing component is used to absorb the energy generated during the vibration of the flow-stabilizing tube, and the adjustment component is used to change the temperature state in the working environment of the water pump.

[0007] Furthermore, the noise reduction component includes a spiral blade arranged inside the flow stabilizing tube, the spiral blade is located on both sides of the water pump, two groups of pipes are arranged inside the flow stabilizing tube, a follower plate is arranged inside the pipe, a cavity is arranged inside the flow stabilizing tube, when water flows through the pipe, the water flows impact the follower plate, so that the spiral blade and the follower plate rotate with the horizontal center line of the flow stabilizing tube as the center of the circle at the same time, and there are three states of water pressure between the water supply pipe and the residential water pipe. First, when the water supply pressure in the water supply pipe is greater than the water flow pressure of the residential water pipe, since the inner diameter of the middle part of the pipe is greater than the inner diameter of the two ends of the pipe, part of the water flow provided by the water supply pipe leaves through the residential water pipe, and the remaining part of the water enters the cavity through the gap of the follower plate, and there is a Two connecting ports, where the water inlet of the cavity is located on the side of the water pipe close to the residential water pipe, and the water inlet of the cavity is located on the side of the water pipe close to the water supply pipe. At this time, the flow rate of the cavity water inlet is greater than the flow rate of the water outlet; secondly, when the water supply pressure in the water supply pipe is equal to the water flow pressure of the residential water pipe, the flow rate provided by the water supply pipe is equal to the input flow rate of the residential water pipe, and at this time the flow rate of the cavity water inlet is equal to the flow rate of the water outlet; thirdly, when the water supply pressure in the water supply pipe is less than the water flow pressure of the residential water pipe, the flow rate provided by the water supply pipe is less than the input flow rate of the residential water pipe, and at this time the flow rate of the cavity water inlet is less than the flow rate of the water outlet, and the water retained in the flow stabilizing tube replenishes the named water pipe. Before the water in the cavity is about to be exhausted, a pressure monitoring element is arranged inside the cavity (Figure A control center (not shown in the figure) is arranged inside the flow-stabilizing tube. The pressure detection element feeds back an electrical signal to the control center, and the control center controls the water pump according to the feedback information. The water pump starts to pump the water in the boosting tube into the cavity, and then supplies the residents' water pipes until the output flow of the water supply pipe can fully support the input flow of the residents' water pipes. The pressure monitoring element feeds back an electrical signal to enable the control center to control the water pump to stop working; while the water flows in the pipeline, the water flows through the follower plate to drive the spiral blades to rotate. When the water pump is working, the internal mechanical structure of the water pump works and generates noise. Since the water pump is located in the annular flow-stabilizing tube, part of the noise passing through the flow-stabilizing tube is absorbed by the flow-stabilizing tube and the water flow inside it, and part of the noise is discharged through the openings on both sides of the flow-stabilizing tube. Open, since the two sides of the water pump are equipped with rotating spiral blades and a special arrangement between the spiral blades and the water pump, the rotating spiral blades drive the airflow to pass through the annular flow stabilizing tube, and the temperature is mainly reduced by the airflow being greater than the water pump in the working state. At the same time, the airflow has a part of sound absorption effect. Secondly, the rotating spiral blades complicate the noise sound wave channel, and further achieve the sound absorption effect. When the water flow inside the flow stabilizing tube suddenly stops, the water flow generates water hammer in the flow stabilizing tube. The water hammer phenomenon carries impact energy to impact the flow stabilizing tube. When the impact water flow passes through the follower plate, part of the energy inside the impact water flow is absorbed by the follower plate, and the remaining energy is absorbed by the flow stabilizing tube, so that the flow stabilizing tube and the annular tube slide on the guide rod.

[0008] Furthermore, the cavity is connected to the water outlet of the water pump, the lowermost end of the cavity is connected to two pipes, the spiral blade is connected to the follower plate, the connection between the spiral blade and the follower plate passes through the flow stabilizing tube, the connection between the spiral blade and the follower plate is annular, and the connection is in a sliding sealing structure with the flow stabilizing tube. The lower end of the follower plate is located in the pipe, and two pipes are passed through the lower part of the flow stabilizing tube. The two ends of the pipes are respectively connected to the expansion joint and the water supply pipe and the residential water pipe. The pipes are located below the flow stabilizing tube, wherein The water pump is located in the middle of the flow stabilizing tube, wherein one end of the water pump is connected to the flow stabilizing tube, and the other end of the water pump is connected to the boosting tube, and the water inlet end of the boosting tube is connected to the water supply pipe. A cavity is arranged inside the flow stabilizing tube, and the cavity is connected to the water outlet of the water pump, wherein the lower end of the cavity is connected to two pipes, wherein the spiral blade is connected to the follower plate, and the connection between the spiral blade and the follower plate passes through the flow stabilizing tube, and the connection between the spiral blade and the follower plate is annular, and the connection with the flow stabilizing tube is a sliding sealing structure, and the lower end of the follower plate is located in the pipe.

[0009] Furthermore, the guide assembly includes an annular tube arranged outside the flow stabilizing tube, guide rods are arranged on both sides of the annular tube, connecting rods are connected at both ends of the annular tube, energy absorbing assemblies are connected at both ends of the connecting rods, and the energy absorbing assemblies are shock absorbers.

[0010] Furthermore, the guide rod is arc-shaped, and the energy absorbing assembly includes an energy absorbing chamber and a piston plate. One end of the energy absorbing chamber is connected to a hydraulic oil chamber, and the piston plate is connected to a connecting rod. A guide structure is arranged inside the energy absorbing chamber, and the guide structure is used to control the flow rate of the hydraulic oil passing through the energy absorbing chamber. The guide rod is connected to an adjusting assembly. Since the guide rod is arc-shaped, the annular tube moves to the lowest point of the arc-shaped guide rod only under the action of gravity. The lowest point of the arc-shaped guide rod is the middle part of the guide rod. The annular tube drives the piston plate to move inside the energy absorbing chamber again. At this time, the gap volume between the piston plate and the baffle plate is reduced, and the hydraulic flow inside the gap moves toward the hydraulic oil chamber under the action of the piston plate. Under the action of the hydraulic oil flow, the movable plate moves toward the baffle plate until the movable plate and the baffle plate are meshed. The movable plate blocks the wedge-shaped hole of the baffle plate, forcing the hydraulic oil in the gap to return to the hydraulic oil chamber only through the through hole. The piston plate continues to move until the annular tube returns to the lowest point of the guide rod.

[0011] Furthermore, the flow guide structure includes a baffle and a movable plate arranged inside the energy absorption chamber, a wedge-shaped hole is arranged in the middle of the baffle, the outer wall size of the movable plate matches the inner wall size of the wedge-shaped hole, side plates are arranged at both ends of the movable plate, the movable plate is slidably connected with the energy absorption chamber through the side plates, a through hole is arranged in the middle of the movable plate, and the annular tube is connected to the energy absorption assembly through a universal shaft and a connecting rod, wherein under normal conditions, the connecting rod is straight and perpendicular to the connecting surface of the piston plate, when the annular tube slides on the guide rod, the annular tube drives the piston plate to move through the universal shaft and the connecting rod, and the connecting rod drives the piston plate away from the baffle, so that the gap volume between the piston plate and the baffle increases, thereby forcing the hydraulic oil in the hydraulic oil chamber to enter the gap between the piston plate and the baffle through the baffle and the movable plate, under the action of the hydraulic oil flow, the baffle and the movable plate are separated, so that the hydraulic oil flow enters the gap through the wedge-shaped hole in the baffle and the through hole in the movable plate, and the piston During the movement of the plate, the guide assembly and the energy absorption assembly cooperate with each other to absorb the remaining kinetic energy of the water flow impact; the outer wall size of the side plate matches the inner wall size of the energy absorption cavity, and the side plates are located on both sides of the movable plate. The existence of the side plates ensures that the horizontal center line of the movable plate coincides with the horizontal center line of the baffle; the guide rod is mounted on the base plate, and a shaft sleeve is provided under the ring tube. The ring tube is connected to the guide rod through the shaft sleeve. The energy absorption cavity and the base plate are connected through a universal shaft, and the connecting rod and the ring tube are connected through the universal shaft. The connecting rod and the energy absorption cavity serve as the connecting structure between the base plate and the ring tube, wherein when the ring tube slides on the guide rod, the connecting rod and the energy absorption cavity are in the same straight line; a block ring is provided on the side of the energy absorption cavity close to the baffle, and the movable plate is located between the block ring and the baffle. The block ring is mainly used to cooperate with the baffle to limit the movement length of the movable plate. The movement length of the movable plate is greater than the width of the movable plate. The block ring mainly realizes that the movable plate is quickly separated from or fitted with the baffle under the action of the hydraulic oil flow.

[0012] Furthermore, the regulating component includes a grid arranged inside the ring tube, and a louver is installed on the side of the grid away from the water pump. Since the existing non-negative pressure pipe network booster water supply equipment mostly works outdoors and is directly exposed to the external environment, the water pump in the non-negative pressure pipe network booster water supply equipment is easily affected by the external temperature. When the external environment temperature is too high, it is necessary to dissipate the heat of the water pump in time to avoid the water pump entering the overheating protection state, thereby affecting the normal water supply of the residents' water pipes. At this time, the louver is in an open state, and the outer wall of one side of the louver is in contact with the outer surface of the grid. When the ring tube slides on the guide rod, the lower end surface of the grid is in contact with the guide rod, so that the grid follows the movement of the ring tube. When the grid is in contact with the guide rod, the grid rotates with the horizontal center line of the ring tube as the center of the circle, and the grid moves relative to the louver, and the louver cleans the dust attached to the surface of the grid to maintain the flow effect between the inner and outer spaces of the ring tube.

[0013] Furthermore, the grid is rotatably connected to the ring tube, and the lower end of the grid passes through the ring tube and is connected to the guide rod. The upper and lower ends of the louver are installed with thermal expansion materials. When the external environment is too low, the upper and lower ends of the louver are installed with thermal expansion materials. When the temperature contacted by the thermal expansion material is lower than the specified temperature, the thermal expansion material automatically contracts, thereby realizing that the thermal expansion material drives the louver to close. The ring tube cooperates with the louver plates at both ends, so that the internal space of the ring tube is converted into a closed state. At this time, the heat generated by the water pump at work forms an internal air circulation in the closed space in the ring tube under the action of the spiral blades in the working state, thereby maintaining the temperature in the space where the water pump is located greater than the external environment temperature; secondly, when the temperature contacted by the thermal expansion material is higher than the specified temperature, the thermal expansion material automatically expands, thereby realizing that the thermal expansion material drives the louver to unfold, and the space in the ring tube is connected with the external environment.

At the same time, the steady flow pipe forms an air flow channel on the outside of the water pump to accelerate the heat generated during the operation of the water pump. The steady flow pipe cooperates with the noise reduction component to form a unidirectional airflow in the middle of the steady flow pipe.

During the movement of the annular pipe on the guide rod, part of the kinetic energy of the annular pipe is used to resist gravity, thereby reducing the movement amplitude of the annular pipe on the guide rod. Secondly, the energy absorption component has the same effect as the existing shock absorber, but the structure is simpler than the existing shock absorber;

[0017] 3. The non-negative pressure pipe network booster and steady flow water supply equipment with a silencing function adjusts the setting and existence of the components so that the thermal expansion material can improve the working environment of the water pump according to the use environment of the water pump, so as to reduce the influence of the external ambient temperature on the working performance of the water pump, ensure that the water pump works at the highest performance state, and then meet the water demand of residents' water pipes. Secondly, the grid cooperates with the guide rod to realize self-cleaning of the grid, so as to facilitate the rapid adjustment of the working environment temperature of the water pump.

[0040] Working principle of the present invention: two pipes 2 are passed through the lower part of the flow stabilizing tube 1, and the two ends of the pipes 2 are respectively connected to the expansion joint, the water supply pipe and the residential water pipe. The pipes 2 are located below the flow stabilizing tube 1, wherein the water pump is located in the middle of the flow stabilizing tube 1, wherein one end of the water pump is connected to the flow stabilizing tube 1, and the other end of the water pump is connected to the boosting pipe 3, and the water inlet end of the boosting pipe 3 is connected to the water supply pipe. A cavity 43 is provided inside the flow stabilizing tube 1, and the cavity 43 is connected to the water outlet of the water pump, wherein the lower end of the cavity 43 is connected to the two pipes 2, wherein the spiral blade 401 is connected to the follower plate 402, and the connection between the spiral blade 401 and the follower plate 402 passes through the flow stabilizing tube 1, and the connection between the spiral blade 401 and the follower plate 402 is annular, and the connection is in a sliding sealing structure with the flow stabilizing tube 1, and the lower end of the follower plate 402 is located in the pipe 2;

[0041] When water flows through the pipe 2, the water flows impact the follower plate 402, causing the spiral blade 401 and the follower plate 402 to rotate at the same time with the horizontal center line of the flow stabilizing pipe 1 as the center of the circle. There are three states of water pressure between the water supply pipe and the residential water pipe. First, when the water supply pressure in the water supply pipe is greater than the water flow pressure of the residential water pipe, since the inner diameter of the middle part of the pipe 2 is greater than the inner diameter of the two ends of the pipe 2, part of the water flow provided by the water supply pipe leaves through the residential water pipe, and the remaining part of the water enters the cavity 43 through the gap of the follower plate 402. Two connecting ports are provided between the cavity 43 and the pipe 2, wherein the water inlet of the cavity 43 is located on the side of the water pipe close to the residential water pipe, and the water inlet of the cavity 43 is located on the side of the water pipe close to the water supply pipe. At this time, the flow rate of the water inlet of the cavity 43 is greater than the flow rate of the water outlet; second, when the water supply pressure in the water supply pipe is equal to the water flow pressure of the residential water pipe, the water supply pipe provides The flow rate is equal to the input flow rate of the resident water pipe, and at this time the flow rate at the water inlet of the cavity 43 is equal to the flow rate at the water outlet; thirdly, when the water supply pressure in the water supply pipe is less than the water flow pressure of the resident water pipe, the flow rate provided by the water supply pipe is less than the input flow rate of the resident water pipe, and at this time the flow rate at the water inlet of the cavity 43 is less than the flow rate at the water outlet, the water retained in the flow stabilizing tube 1 replenishes the named water pipe, and before the water in the cavity 43 is about to be consumed, a pressure monitoring element is provided in the cavity 43, and a control center is provided in the flow stabilizing tube 1, and the pressure detection element feeds back an electrical signal to the control center, and the control center controls the water pump according to the feedback information, and the water pump starts to pump the water in the boosting pipe 3 into the cavity 43, thereby replenishing the resident water pipe, until the output flow rate of the water supply pipe can fully support the input flow rate of the resident water pipe, and the pressure monitoring element feeds back an electrical signal to enable the control center to control the water pump to stop working;

[0042] When the water flows in the pipe 2, the water flows through the follower plate 402 to drive the spiral blade 401 to rotate. When the water pump is working, the internal mechanical structure of the water pump works and generates noise. Since the water pump is located in the annular flow-stabilizing tube 1, part of the noise passing through the flow-stabilizing tube 1 is absorbed by the flow-stabilizing tube 1 and the water flow inside the flow-stabilizing tube 1, and part of the noise leaves through the openings on both sides of the flow-stabilizing tube 1. Since the two sides of the water pump are spiral blades 401 in a rotating state and there is a special arrangement between the spiral blades 401 and the water pump, the spiral blades 401 in a rotating state drive the airflow to pass through the annular flow-stabilizing tube 1, and the water pump is mainly cooled by the airflow being greater than the working state. At the same time, the airflow has a part of sound absorption effect. Secondly, the spiral blades 401 in a rotating state complicate the noise sound wave channel, thereby further achieving the sound absorption effect.

[0043] When the water flow inside the flow stabilizing tube 1 suddenly stops, a water hammer phenomenon occurs in the flow stabilizing tube 1. The water hammer phenomenon is accompanied by impact energy to impact the flow stabilizing tube 1. When the impact water flow passes through the follower plate 402, part of the energy inside the impact water flow is absorbed by the follower plate 402, and the remaining energy is absorbed by the flow stabilizing tube 1, so that the flow stabilizing tube 1 and the ring tube 501 slide on the guide rod 502.

[0044] The annular tube 501 is connected to the energy absorption component 6 through the universal shaft and the connecting rod 503, wherein in normal state, the connecting rod 503 is straight and perpendicular to the connecting surface of the piston plate 602. When the annular tube 501 slides on the guide rod 502, the annular tube 501 drives the piston plate 602 to move through the universal shaft and the connecting rod 503, and the connecting rod 503 drives the piston plate 602 away from the baffle plate 603, so that the gap volume between the piston plate 602 and the baffle plate 603 increases, thereby forcing the hydraulic oil in the hydraulic oil chamber to enter the gap between the piston plate 602 and the baffle plate 603 through the baffle plate 603 and the movable plate 604. Under the action of the hydraulic oil flow, the baffle plate 603 and the movable plate 604 are separated, so that the hydraulic oil flow enters the gap through the wedge-shaped hole in the baffle plate 603 and the through hole 605 in the movable plate 604. During the movement of the piston plate 602, the guide component 5 and the energy absorption component 6 cooperate with each other to absorb the remaining kinetic energy of the water flow impact;

[0045] Since the guide rod 502 is arc-shaped, the annular tube 501 moves to the lowest point of the arc-shaped guide rod 502 only under the action of gravity. The lowest point of the arc-shaped guide rod 502 is the middle part of the guide rod 502. The annular tube 501 drives the piston plate 602 to move inside the energy absorption chamber 601 again. At this time, the gap volume between the piston plate 602 and the baffle plate 603 is reduced, and the hydraulic flow inside the gap moves to the hydraulic oil chamber under the action of the piston plate 602. Under the action of the hydraulic oil flow, the movable plate 604 moves toward the baffle plate 603 until the movable plate 604 and the baffle plate 603 are meshed, and the movable plate 604 blocks the wedge-shaped hole of the baffle plate 603, forcing the hydraulic oil in the gap to return to the hydraulic oil chamber only through the through hole 605. The piston plate 602 continues to move until the annular tube 501 returns to the lowest point of the guide rod 502.

[0046] Since the existing non-negative pressure pipe network booster water supply equipment mostly works outdoors, the non-negative pressure pipe network booster water supply equipment is directly exposed to the external environment, and the water pump in the non-negative pressure pipe network booster water supply equipment is easily affected by the external temperature. When the external environment temperature is too high, the water pump needs to be cooled in time to avoid the water pump entering the overheating protection state, thereby affecting the normal water supply of the residents' water pipes. At this time, the louver plate 702 is in an open state, and the outer wall of one side of the louver plate 702 is in contact with the outer surface of the grid 701, wherein the ring pipe When the mesh 701 slides on the guide rod 502, the lower end surface of the mesh 701 fits with the guide rod 502, so that the mesh 701 follows the movement of the ring tube 501. When the mesh 701 is in contact with the guide rod 502, the mesh 701 rotates with the horizontal center line of the ring tube 501 as the center of the circle, and the mesh 701 moves relative to the louver plate 702. The louver plate 702 cleans the dust attached to the surface of the mesh 701 to maintain the flow effect between the inner and outer spaces of the ring tube 501.

[0047] Secondly, when the external environment is too low, thermal expansion materials are installed at the upper and lower ends of the louver 702. When the temperature contacted by the thermal expansion material is lower than the specified temperature, the thermal expansion material automatically contracts, thereby realizing that the thermal expansion material drives the louver 702 to be closed. The annular tube 501 cooperates with the louver 702 at both ends, so that the internal space of the annular tube 501 is converted into a closed state. At this time, the heat generated by the water pump at work forms an internal air circulation in the closed space of the annular tube 501 under the action of the spiral blades 401 in the working state, thereby maintaining the temperature in the space where the water pump is located higher than the external environment temperature.
