Description

Technical Field

[0001] The present application belongs to the technical field of water supply equipment, and in particular, relates to a water supply equipment. Background Art

[0002] Since the water supply equipment was put into promotion, tank-type non-negative pressure water supply equipment has been widely used. However, for some areas with insufficient water supply or concentrated water use such as buildings, residential areas, development zones, booster pump stations, and some places that require a certain amount of water storage capacity, such as hospitals, schools, hotels, etc., box-type constant pressure variable frequency water supply equipment can meet their use requirements. Compared with tank-type non-negative pressure water supply equipment, box-type constant pressure variable frequency water supply equipment has a more stable water supply pressure and less water pressure fluctuation. However, the existing box-type constant pressure variable frequency water supply equipment has the problem of large footprint and long length, which limits its application. Utility Model Content

[0003] The purpose of this application is to at least solve the problem of large footprint of water supply equipment. This purpose is achieved through the following technical solutions:

[0004] The present application proposes a water supply device, comprising:

[0005] Base;

[0006] A booster device, mounted on the base, comprising a plurality of water pumps arranged along a first direction, the water pumps being connected to a water inlet manifold and a water outlet manifold, at least a portion of the water inlet manifold being located on one side of the booster device along a second direction, the first direction being perpendicular to a thickness direction of the base, the second direction being perpendicular to the thickness direction of the base and perpendicular to the first direction;

[0007] A horizontal diaphragm air pressure tank is located on one side of the booster device along the second direction and on a side of the water inlet manifold away from the base, is installed on the base through a connector and is connected to the water outlet manifold.

[0008] In the above-mentioned water supply equipment provided by the present application, since at least part of the water inlet manifold is located on one side of the boosting device along the second direction, the orthographic projection of at least part of the water inlet manifold on the base does not overlap with the orthographic projection of the boosting device on the base, so that there is a certain space on the side of the water inlet manifold away from the base. The horizontal diaphragm air pressure tank is located on one side of the boosting device along the second direction and on the side of the water inlet manifold away from the base, so that the orthographic projection of the horizontal diaphragm air pressure tank on the base does not overlap with the orthographic projection of the boosting device on the base. The horizontal diaphragm air pressure tank is fixed to the base by a connector, and the connector can set up the horizontal diaphragm air pressure tank to avoid the water inlet manifold. Arranging the horizontal diaphragm air pressure tank on the side of the water inlet manifold away from the base can utilize the space on the side of the water inlet manifold away from the base. Since the height of the water pump, that is, the size of the water pump along the thickness direction of the base is large, there can be a larger space on the side of the water inlet manifold away from the base. Arranging the horizontal diaphragm air pressure tank on the side of the water inlet manifold away from the base can improve the compactness of the water supply equipment. Since at least part of the water inlet manifold is located on the side of the boosting device along the second direction, the second direction is perpendicular to the thickness direction of the base and perpendicular to the first direction, arranging the horizontal diaphragm air pressure tank on the side of this part of the water inlet manifold away from the base can make the horizontal diaphragm air pressure tank located on the side of the boosting device along the second direction, thereby avoiding the increase in the size of the water supply equipment along the first direction caused by the arrangement of the horizontal diaphragm air pressure tank. At the same time, the orthographic projection of the horizontal diaphragm air pressure tank on the base does not overlap with the orthographic projection of the booster device on the base, that is, the horizontal diaphragm air pressure tank is not located on the side of the water pump away from the base, so that the height of the end of the horizontal diaphragm air pressure tank away from the base along the thickness direction of the base can be lower than or equal to the height of the end of the water pump away from the base along the thickness direction of the base, thereby reducing the size of the water supply equipment along the thickness direction of the base. The water supply equipment provided in the present application has a small footprint, thereby saving space and making the application scenarios of the water supply equipment more extensive.

[0009] In some embodiments of the present application, the orthographic projection of the horizontal diaphragm air pressure tank in the second direction is located within the orthographic projection range of the boosting device in the second direction.

[0010] In some embodiments of the present application, the plurality of water pumps include a main pump and an auxiliary pump, and the power of the auxiliary pump is smaller than the power of the main pump.

[0011] In some embodiments of the present application, the number of the main pumps is greater than the number of the auxiliary pumps.

[0012] In some embodiments of the present application, an intelligent control box is also included, which is installed on the base and is connected to the boost device by signal.

[0013] In some embodiments of the present application, a pressure switch and a pressure transmitter are installed on the water outlet manifold, the pressure switch is electrically connected to the water pump to control the start and stop of the water pump, and the pressure transmitter is signal-connected to the smart control box to detect the water pressure in the water outlet manifold.

[0014] In some embodiments of the present application, the connecting member includes two tank support plates arranged opposite to each other, the tank support plates are connected to the base, and both ends of the horizontal diaphragm air pressure tank are respectively connected to the tank support plates.

[0015] In some embodiments of the present application, a metal cladding plate is further included, and the metal cladding plate is wrapped around the outer side of the tank support plate.

[0016] In some embodiments of the present application, the horizontal diaphragm air pressure tank includes an annular connecting piece, which is arranged around the circumference of the horizontal diaphragm air pressure tank and is fixedly connected to the horizontal diaphragm air pressure tank, a first connecting hole is formed on the annular connecting piece, and a second connecting hole corresponding to the first connecting hole is formed on the tank body support plate, and the annular connecting piece and the tank body support plate are fixed by fasteners passing through the first connecting hole and the second connecting hole.

[0029] like Figure 1 and Figure 2 As shown, according to the embodiment of the present application, a water supply device 1 is proposed, comprising a base 11, a booster device 12 and a horizontal diaphragm air pressure tank 15. The booster device 12 is installed on the base 11, and the booster device 12 comprises a plurality of water pumps 121 arranged along a first direction x, and the water pumps 121 are connected to a water inlet manifold 13 and a water outlet manifold 14, and at least part of the water inlet manifold 13 is located on one side of the booster device 12 along a second direction y, the first direction x is perpendicular to the thickness direction z of the base 11, and the second direction y is perpendicular to the thickness direction z of the base 11 and perpendicular to the first direction x. The horizontal diaphragm air pressure tank 15 is located on one side of the booster device 12 along the second direction y and on the side of the water inlet manifold 13 away from the base 11, and is installed on the base 11 through a connector 16 and connected to the water outlet manifold 14.

[0030] The above-mentioned water supply equipment 1 provided by the present application includes a base 11, a booster device 12 and a horizontal diaphragm air pressure tank 15, wherein the base 11 is used to fix other components in the water supply equipment 1 and facilitate the stability of the equipment. The booster device 12 includes a plurality of water pumps 121, and the plurality of water pumps 121 are arranged along the first direction x. The booster device 12 is connected to the water inlet manifold 13 and the water outlet manifold 14, and is used to pressurize the water entering the water pump 121 from the water inlet manifold 13, thereby improving the stability of the water supply water pressure and meeting the needs of users. The horizontal diaphragm air pressure tank 15 is connected to the water outlet manifold 14, and can separate water and air through a diaphragm to avoid direct contact between water and air, and reduce the problem of oxidation and corrosion in water. At the same time, the horizontal diaphragm air pressure tank 15 can also play the role of water storage. When the water pump 121 stops working, the water in the horizontal diaphragm air pressure tank 15 can still be used for water for users, thereby reducing the number of starts and stops of the water pump 121 to extend the service life of the water pump 121. In addition, the horizontal diaphragm air pressure tank 15 can also be used to alleviate the pressure shock when the water pump 121 is working, and control the start and stop of the water pump 121 by adjusting the air pressure, thereby achieving more intelligent control of the water pump 121.

[0031] In the above-mentioned water supply equipment 1 provided by the present application, since at least part of the water inlet manifold 13 is located on one side of the boosting device 12 along the second direction y, the orthographic projection of at least part of the water inlet manifold 13 on the base 11 does not overlap with the orthographic projection of the boosting device 12 on the base 11, so that there is a certain space on the side of the water inlet manifold 13 away from the base 11. The horizontal diaphragm air pressure tank 15 is located on one side of the boosting device 12 along the second direction y and on the side of the water inlet manifold 13 away from the base 11, so that the orthographic projection of the horizontal diaphragm air pressure tank 15 on the base 11 does not overlap with the orthographic projection of the boosting device 12 on the base 11. The horizontal diaphragm air pressure tank 15 is fixed to the base 11 by a connector 16, and the connector 16 can set up the horizontal diaphragm air pressure tank 15 to avoid the water inlet manifold 13. Arranging the horizontal diaphragm air pressure tank 15 on the side of the water inlet manifold 13 away from the base 11 can utilize the space on the side of the water inlet manifold 13 away from the base 11. Since the height of the water pump 121, that is, the size of the water pump 121 along the thickness direction of the base 11 is large, there can be a larger space on the side of the water inlet manifold 13 away from the base 11. Arranging the horizontal diaphragm air pressure tank 15 on the side of the water inlet manifold 13 away from the base 11 can improve the compactness of the water supply equipment 1. Since at least part of the water inlet manifold 13 is located on the side of the boosting device 12 along the second direction y, the second direction y is perpendicular to the thickness direction z of the base 11 and perpendicular to the first direction x, arranging the horizontal diaphragm air pressure tank 15 on the side of this part of the water inlet manifold 13 away from the base 11 can make the horizontal diaphragm air pressure tank 15 located on the side of the boosting device 12 along the second direction y, thereby avoiding the increase in the size of the water supply equipment 1 along the first direction x caused by the arrangement of the horizontal diaphragm air pressure tank 15. At the same time, the orthographic projection of the horizontal diaphragm air pressure tank 15 on the base 11 does not overlap with the orthographic projection of the booster device 12 on the base 11, that is, the horizontal diaphragm air pressure tank 15 is not located on the side of the water pump 121 away from the base 11, so that the height of the end of the horizontal diaphragm air pressure tank 15 away from the base 11 along the thickness direction z of the base 11 can be lower than or equal to the height of the end of the water pump 121 away from the base 11 along the thickness direction z of the base 11, thereby reducing the size of the water supply equipment 1 along the thickness direction z of the base 11. The water supply equipment 1 provided in the present application has a small footprint, thereby saving space and making the application scenarios of the water supply equipment 1 more extensive.

[0032] In addition, the size of the horizontal diaphragm air pressure tank 15 along the first direction x can be greater than the size along the thickness direction z of the base 11, and the size of the horizontal diaphragm air pressure tank 15 along the first direction x can be greater than the size along the second direction y, that is, the size of the horizontal diaphragm air pressure tank 15 along the first direction x is maximized, so as to make full use of the space defined by the size of the booster device 12 along the first direction x, and minimize the size of the water supply equipment 1 along the second direction y and along the thickness direction z of the base 11, so that the footprint of the water supply equipment 1 is smaller. In the above embodiment, the length direction of the horizontal diaphragm air pressure tank 15 can be parallel to the first direction x, so that the space defined by the size of the booster device 12 along the first direction x can be fully utilized, and the size of the water supply equipment 1 along the second direction y and along the thickness direction z of the base 11 can be reduced, so that the size of the water supply equipment 1 is smaller.

[0033] Specifically, Figure 3 and Figure 4 As shown, one end of the horizontal diaphragm air pressure tank 15 along its own length direction is connected to the water outlet manifold 14 through a connecting pipe 152. The connecting pipe 152 may include a first section and a second section. The first section extends along the thickness direction z of the base, and one end of the first section is connected to the horizontal diaphragm air pressure tank 15, and the other end is connected to the second section. The second section extends along the second direction y and is connected to the water outlet manifold 14.

[0034] Specifically, the base 11 may be a channel steel base 11 , and the base 11 and the ground may be fixed by expansion bolts to improve the stability of the water supply equipment 1 .

[0035] Specifically, the horizontal diaphragm air pressure tank 15 is made of stainless steel to avoid secondary pollution of the water quality.

[0036] Specifically, the horizontal diaphragm air pressure tank 15 can be configured with various specifications and volumes according to the user's water usage.

[0037] In a possible implementation, Figure 2 As shown, the orthographic projection of the horizontal diaphragm air pressure tank 15 in the second direction y is located within the orthographic projection range of the boosting device 12 in the second direction y.

[0038] In the above embodiment, the orthographic projection of the horizontal diaphragm air pressure tank 15 in the second direction y is located within the orthographic projection range of the booster device 12 in the second direction y, so that the height of the end of the horizontal diaphragm air pressure tank 15 away from the base 11 along the thickness direction z of the base 11 is lower than or equal to the height of the end of the water pump 121 away from the base 11 along the thickness direction z of the base 11, thereby reducing the size of the water supply equipment 1 along the thickness direction z of the base 11. And the two ends of the horizontal diaphragm air pressure tank 15 along the first direction x do not exceed the limited range of both sides of the booster device 12 along the first direction x, thereby further reducing the size of the water supply equipment 1 along the first direction x.

[0039] In a possible implementation, Figure 1 As shown, the connecting member 16 includes two tank support plates 161 arranged opposite to each other, the tank support plates 161 are connected to the base 11 , and both ends of the horizontal diaphragm air pressure tank 15 are respectively connected to the tank support plates 161 .

[0040] In the above embodiment, the tank support plate 161 is vertically arranged with respect to the base 11 and is mounted on the base 11 by bolts.

[0041] In the above embodiment, the two tank support plates 161 can be arranged relatively along the first direction x so that the two ends of the horizontal diaphragm air pressure tank 15 are arranged along the first direction x, thereby making full use of the space defined by the size of the boosting device 12 along the first direction x to reduce the footprint of the water supply equipment 1.

[0042] In a possible implementation, Figure 2 As shown, the horizontal diaphragm air pressure tank 15 includes an annular connector 151, which is arranged around the circumference of the horizontal diaphragm air pressure tank 15 and is fixedly connected to the horizontal diaphragm air pressure tank 15. A first connecting hole 1511 is formed on the annular connector 151, and a second connecting hole corresponding to the first connecting hole 1511 is formed on the tank body support plate 161. The annular connector 151 and the tank body support plate 161 are fixed by fasteners passing through the first connecting hole 1511 and the second connecting hole.

[0043] In the above embodiment, the horizontal diaphragm air pressure tank 15 may include a cylindrical structure, the outer periphery of the cylindrical structure is welded and fixed to the annular connector 151, a first connecting hole 1511 is formed on the annular connector 151, and a second connecting hole corresponding to the first connecting hole 1511 is formed on the tank body support plate 161. The fastener may include a bolt, and the annular connector 151 can be fixedly connected to the tank body support plate 161 by the bolt, and the bolt passes through the first connecting hole 1511 and the second connecting hole in sequence and fixes the annular connector 151 to the tank body support plate 161.

[0044] In another feasible implementation, the annular connector 151 may also be welded and fixed to the tank support plate 161 , which is not particularly limited in the present application.

[0045] In a possible implementation, Figure 2 As shown, it also includes a metal cladding plate 17, which is wrapped around the outside of the tank support plate 161. This improves the aesthetics of the water supply device 1, protects the tank support plate 161, reduces the impact of external factors on the installation yield of the horizontal diaphragm air pressure tank 15 and the tank support plate 161, and improves the yield of the water supply device 1.

[0046] In a possible implementation, Figure 1 , Figure 2 and Figure 3 As shown, the plurality of water pumps 121 include a main pump 1211 and an auxiliary pump 1212 , and the power of the auxiliary pump 1212 is less than that of the main pump 1211 .

[0047] When the water pump 121 runs at a low speed for a long time or starts and stops frequently, such as water use at night or small flow during the day, in order to reduce the energy consumption of the water supply equipment 1, the main pump 1211 can be disabled and the auxiliary pump 1212 with lower power can be enabled to reduce the energy consumption of the water supply equipment 1 on the basis of meeting user needs, and reduce the loss of the main pump 1211 caused by long-term low-speed operation or frequent start and stop, thereby helping to increase the service life of the main pump 1211. The water supply method using the main pump 1211 with the auxiliary pump 1212 can make full use of the peak and low-peak interval characteristics of user water use, making the water supply method more energy-efficient.

[0048] Specifically, the number of main pumps 1211 can be greater than the number of auxiliary pumps 1212. The main pump 1211 is the main component of the boosting device 12 and has a stronger boosting effect. The auxiliary pump 1212 has weaker power, so the number can be set to be smaller. The main pump 1211 can be enabled when stronger power pressurization is required.

[0049] Specifically, there may be two main pumps 1211 and one auxiliary pump 1212, which is not particularly limited in the present application.

[0050] In the above-mentioned embodiment, the water pump 121 can be a permanent magnetic intelligent pump. Compared with the traditional water pump 121, the motor used in the traditional water pump 121 is a three-phase asynchronous motor, and an intelligent control box needs to be set up, and a frequency converter is independently configured in the intelligent control box, so it is necessary to independently set up a cement foundation for the intelligent control box. The water supply equipment 1 of the present application adopts a permanent magnetic intelligent pump, and the control box and the pressurizing unit in the water pump 121 are an integrated structure to form a permanent magnetic intelligent pump, so there is no need to set up a frequency converter in the intelligent control box 18, and there is no need to build a cement foundation for the intelligent control box 18, so that the water supply equipment 1 provided by the present application occupies a smaller site, is applicable to a wider range of scenarios, and is also applicable to occasions where the space of the pump room is limited.

[0051] In a possible implementation, Figure 1 and Figure 2 As shown, it also includes an intelligent control box 18 , which is installed on the base 11 , and the intelligent control box 18 is connected to the boosting device 12 by signal.

[0052] In the above embodiment, the intelligent control box 18 is directly installed on the base 11, and there is no need to build a new cement foundation for the intelligent control box 18, so that the water supply equipment 1 provided in the present application occupies a smaller site and has a wider range of applicable scenarios. It is also applicable to occasions where the space in the pump room is limited, and saves installation costs.

[0053] Specifically, the intelligent control box 18 may be located at one side of the supercharging device 12 along the first direction x.

[0054] In the above embodiment, the intelligent control box 18 is located on one side of the booster device 12 along the first direction x, so that the distance between the intelligent control box 18 and the booster device 12 and the horizontal diaphragm air pressure tank 15 is relatively close, so as to reduce the length of the cable connecting the booster device 12 and the intelligent control box 18, and reduce the length of the cable connecting the horizontal diaphragm air pressure tank 15 and the intelligent control box 18. Thereby, the installation cost and construction difficulty of the cable can be reduced, and the maintenance cost can be reduced.

[0055] Specifically, the intelligent control box 18 is connected to the supercharging device 12 via signals so as to control the supercharging device 12 .

[0056] In a possible implementation, Figure 2 As shown, a pressure switch 19 is installed on the water outlet manifold 14 , and the pressure switch 19 is electrically connected to the water pump 121 to control the start and stop of the water pump 121 .

[0057] In the above embodiment, the pressure switch 19 mainly functions to detect the water pressure in the water supply device 1. When the water pressure reaches the set value, the water pump 121 is automatically started and stopped to ensure the normal operation of the water supply system.

[0058] In a possible implementation, Figure 2 As shown, it also includes a pressure transmitter 20, which is installed on the water outlet manifold 14. The pressure transmitter 20 is signal-connected to the intelligent control box 18, and the intelligent control box 18 is signal-connected to the boosting device 12. The pressure transmitter 20 is signal-connected to the intelligent control box 18 for detecting the water pressure in the water outlet manifold 14.

[0059] In the above embodiment, the pressure transmitter 20 converts the water pressure in the water outlet manifold 14 into an electrical signal and transmits it to the intelligent control box 18. The intelligent control box 18 controls the operating speed and frequency of the main pump 1211 through the electrical signal, adjusts the pressure and flow rate output by the water pump 121, thereby maintaining a constant water pressure to supply water to users.

[0060] In the above embodiment, when the water pressure monitored by the pressure transmitter 20 on the outlet manifold 14 reaches the target setting value, and the main pump 1211 has been running at a low frequency for a preset time, the intelligent control box 18 controls the main pump 1211 to stop, and controls the auxiliary pump 1212 to start, and the power of the auxiliary pump 1212 is smaller than that of the main pump 1211, thereby achieving the effect of reducing energy consumption. The target setting value and the preset time can be set according to actual needs, and this application does not make any special restrictions on this.

[0061] Specifically, the operating time of the main pump 1211 can be monitored by the intelligent control box 18.

[0062] In the above embodiment, the intelligent control box 18 is located on one side of the boosting device 12 along the first direction x, a water meter and a valve are provided on the pipeline connecting the water outlet manifold 14 and the user, a control cable is installed on the water pump 121, a signal cable is installed on the pressure switch 19 and the pressure transmitter 20, and a signal cable is installed on the water meter. These control cables and signal cables can be directly connected to the intelligent control box 18, and the control cables and signal cables are close to the intelligent control box 18, so that the cable length is short, so as to reduce the cost and facilitate construction and maintenance.

[0063] The water supply equipment 1 provided in the present application also includes a water tank, and the booster device 12 is connected to the water tank through a water inlet manifold 13, and a water inlet valve is installed on the water inlet manifold 13. Specifically, the water pump 121 is connected to the water inlet manifold 13 through valves and pipe fittings, and the water inlet manifold 13 is connected to the water outlet of the water tank. The water tank is a closed structure and is made of stainless steel to avoid secondary pollution of the water quality. The water pump 121 is connected to the water outlet pipe through a valve and a check valve 21. The pipelines and valves in the water supply equipment 1 are all made of stainless steel to avoid secondary pollution of the water quality.

[0064] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
