[0002] Gas pipeline stations are key nodes in long-distance natural gas pipeline systems, used to receive natural gas from gas sources and transport it to downstream stations or users. Gas pipeline stations need to be equipped with water supply facilities to provide domestic water to the gas pipeline stations.

[0003] In related technologies, the water supply equipment of gas pipeline stations includes water tanks, water pumps and connecting pipes. The water tanks and water pumps are connected by connecting pipes. The water tanks, water pumps and connecting pipes are arranged in a decentralized manner, which results in a large footprint. In addition, the connecting pipes are exposed, which affects the movement of staff and reduces the operating space of staff when they carry out maintenance, thus affecting the convenience of maintenance. Utility Model Content

[0004] The purpose of this application is to provide a water supply device that aims to solve the technical problems of current water supply devices having a large footprint and affecting the convenience of maintenance for staff.

[0005] This application provides a water supply device, which includes: A support frame, the support frame having an accommodating space, the top of the support frame having a top plate, the top plate having a supporting surface; A water tank is disposed on the supporting surface and connected to the top plate, and the water tank is provided with a storage space; A water pump, a connecting pipe, and a water supply pipe are provided. The water pump is located in the accommodating space and has an inlet and an outlet. One end of the connecting pipe is connected to the inlet, and the other end of the connecting pipe passes through the top plate to connect to the storage space. One end of the water supply pipe is connected to the outlet, and the other end is connected to the conveying pipe.

[0006] In the above-mentioned solution, the water supply equipment provided by this disclosure includes a support frame, a water tank, and a water pump. The water pump is placed within the accommodating space of the support frame, and the water tank is placed on the top support surface of the support frame. The floor area of ​​the water supply equipment is the same as that of the support frame, thereby reducing the overall space occupied by the water supply equipment. Furthermore, the connecting pipe between the water tank and the water pump passes through the top plate, placing it between the water tank and the water pump. The water supply pipe of the water pump extends underground to connect with the delivery pipe, thus ensuring that the connecting pipe and the water supply pipe are located within the area of ​​the support frame, without requiring additional space. Moreover, the arrangement of the connecting pipe and the water supply pipe does not occupy the space occupied by the water pump and the water tank, increasing the operating space for staff and thus increasing the convenience of maintenance.

[0007] Optionally, the water supply equipment further includes a water quality cleaning device and a cleaning pipe. The water quality cleaning device is adapted to release cleaning agent. One end of the cleaning pipe is connected to the storage space, and the other end of the cleaning pipe is connected to the cleaning agent delivery port of the water quality cleaning device.

[0008] In the above scheme, since the water supply equipment also includes a water quality cleaning device and a cleaning pipeline, the water quality cleaning device can deliver the cleaning agent to the storage space through the cleaning pipeline to sterilize the water body, maintain the stability of the water quality, and ensure the safety and reliability of the water supply.

[0009] Optionally, the water supply equipment further includes a water quality testing device, which is located in the storage space and connected to the water tank. The water quality testing device is used to test the water quality and is electrically connected to the water quality cleaning device. The water quality cleaning device is adapted to release the cleaning agent when the water quality is lower than a preset standard.

[0010] In the above scheme, since the water supply equipment also includes a water quality detection device, when the water quality detection device detects that the water quality is lower than the preset water quality, it will feed back a cleaning signal to the control module. The control module will then control the water quality cleaning device to release cleaning agent to achieve automatic cleaning of the water body, reduce manual intervention, lower labor costs, and provide a fast response.

[0011] Optionally, the water purification device includes an ozone generator.

[0012] In the above scheme, since ozone cannot be stored for a long time, this application sets up an ozone generator to produce ozone on its own, and then transports the ozone to the storage space of the water tank to meet the sterilization needs of the water body.

[0013] Optionally, the water cleaning device further includes an ozone generator, which is disposed in the storage space and connected to the water tank, and one end of the cleaning pipe is connected to the ozone generator.

[0014] In the above solution, since the water quality cleaning device also includes an ozone generator, the ozone generated by the ozone generator enters the ozone generator through the cleaning pipe, and is then released into the water tank through the ozone generator. Therefore, the ozone can be fully mixed with the water through the ozone generator to eliminate bacteria in the water and increase the water quality cleaning effect.

[0015] Optionally, the ozone generator is connected to the water tank; or, the ozone generator is connected to the support frame; or, the ozone generator is connected to an external support structure.

[0016] In the above solutions, the ozone generator can be connected to the water tank; or, the ozone generator can be connected to the support frame; or, the ozone generator can be connected to the external support structure. This design can reduce the space occupied by the ozone generator on the ground, thereby reducing the space occupied by the entire water supply equipment.

[0017] Optionally, the water supply device further includes an overflow pipe, the top end of which is connected to a preset position on the top of the water tank, the top opening of which is vertically upward and communicates with the storage space, and the bottom end of which passes through the side wall of the water tank and communicates with a floor drain.

[0018] In the above solution, since the water supply equipment also includes an overflow pipe, when the water level in the tank is too high, the excess water will flow to the floor drain through the overflow pipe, preventing water from overflowing from the top of the tank, eliminating the risk of overflow, and ensuring the safety of the water supply equipment.

[0019] Optionally, the water supply equipment further includes a drain pipe, the top end of which is connected to the bottom of the water tank and communicates with the storage space, and the bottom end of which passes through the top plate and communicates with the floor drain.

[0020] In the above solution, since the water supply equipment also includes a drainage pipe, when the water tank is cleaned and sewage is discharged, the drainage pipe will be opened, and the sewage in the water tank will be discharged to the floor drain through the drainage pipe, thereby increasing the convenience of sewage discharge.

[0021] Optionally, the water supply equipment further includes a water inlet pipe, one end of which is connected to the water tank and communicates with the storage space, and the other end of which is used to connect to a water source.

[0022] In the above scheme, when the water level in the water tank is too low, the pump can pump the water stored in the water truck into the water tank through the water inlet pipe to provide water to the water tank and increase the convenience of water intake for the water tank.

[0023] Optionally, the support frame includes multiple legs, which are spaced apart at the bottom of the top plate and connected to the top plate, and the multiple legs and the top plate form the accommodating space.

[0024] In the above scheme, the support frame has a simple structure and can provide a stable support foundation. At the same time, the water pump is placed in the accommodation space enclosed by multiple support legs and the top plate. The accommodation space is large, and the staff can operate through the space between two adjacent support legs, which increases the convenience of water pump installation and maintenance.

For example, "parallel" includes absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity can also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, where the acceptable deviation range for approximate equality can be, for example, a difference between the two equals being less than or equal to 5% of either one.

[0032] like Figure 1 As shown in the figure, this application embodiment provides a water supply device, which includes a support frame 1, a water tank 2, a water pump 3, a connecting pipe 31, and a water supply pipe 32. The bottom of the support frame 1 is used for support on the ground. The support frame 1 has a receiving space 11, which can be a cube, cuboid, cylinder, or other irregular shape, without restriction. The receiving space 11 can be formed in the middle or at the bottom of the support frame 1, without restriction. The top of the support frame 1 has a top plate 12, which has a supporting surface parallel to the horizontal plane. The water tank 2 is placed on the supporting surface and connected to the top plate 12, so that the water tank 2 can be placed on the supporting surface and connected to the top plate 12 to ensure the stability of the position of the water tank 2. The connection method can be welding or bolt connection, without restriction. The water tank 2 has a storage space 21. The shape of the storage space 21 can be a cube, cuboid, cylinder, or other irregular shape, without restriction. The size of the storage space 21 is also unrestricted and can be designed according to actual needs. The storage space 21 is used to store water. The water pump 3 is installed in the accommodating space 11. The water pump 3 can be placed in the accommodating space 11, or it can be placed in the accommodating space 11 and connected to the support frame 1 to increase the stability of the water pump 3 installation; there are no restrictions. The water pump 3 has an inlet and an outlet. One end of the connecting pipe 31 is connected to the inlet, and the other end of the connecting pipe 31 passes through the top plate 12 to connect to the storage space 21. One end of the water supply pipe 32 is connected to the outlet, and the other end is connected to the delivery pipe, which is a buried pipe. In use, the water pump 3 can pump water from the water tank 2 through the connecting pipe 31, transport it through the water supply pipe 32 to the delivery pipe, and then transport it to the target location through the delivery pipe.

[0033] In some embodiments, a connecting valve is provided on the connecting pipe 31. The connecting valve is used to control the opening and closing of the connecting pipe 31, and the connecting valve can be a manual valve or an automatic valve, without limitation. Wherein, when the connecting valve is an automatic valve, the automatic valve is electrically connected to the control module so that the control module can control the opening and closing of the connecting valve.

[0034] In some embodiments, a water supply valve is provided on the water supply pipeline 32. The water supply valve is used to control the opening and closing of the water supply pipeline 32, and the water supply valve can be a manual valve or an automatic valve, without limitation. Among them, when the water supply valve is an automatic valve, the automatic valve is electrically connected to the control module so that the control module can control the opening and closing of the water supply valve.

[0035] The water supply equipment provided in this embodiment includes a support frame 1, a water tank 2, and a water pump 3. The water pump 3 is placed in the accommodating space 11 of the support frame 1, and the water tank 2 is placed on the top support surface of the support frame 1. The floor area of ​​the water supply equipment is the same as that of the support frame 1, thereby reducing the space occupied by the entire water supply equipment. The connecting pipe 31 between the water tank 2 and the water pump 3 passes through the top plate 12, so that it is located between the water tank 2 and the water pump 3. The water supply pipe 32 of the water pump 3 extends into the ground to connect with the delivery pipe. Thus, the connecting pipe 31 and the water supply pipe 32 are located within the area of ​​the support frame 1, without adding extra space. Moreover, the arrangement of the connecting pipe 31 and the water supply pipe 32 does not occupy the space of the water pump and the water tank 2, increasing the operating space of the staff and thus increasing the convenience of maintenance.

[0036] In some implementations, such as Figure 1 As shown, the water supply equipment also includes a water quality cleaning device 4 and a cleaning pipe 5. The water quality cleaning device 4 is suitable for releasing cleaning agents, such as ozone, hydrogen peroxide, sodium hypochlorite, etc., without limitation. One end of the cleaning pipe 5 is connected to the storage space 21, and the other end of the cleaning pipe 5 is connected to the cleaning agent delivery port of the water quality cleaning device 4, so that the water quality cleaning device 4 and the storage space 21 are connected through the cleaning pipe 5, so that the water quality cleaning device 4 can release cleaning agents toward the storage space 21.

[0037] In this design, since the water supply equipment also includes a water quality cleaning device 4 and a cleaning pipe 5, the water quality cleaning device 4 can deliver the cleaning agent to the storage space 21 through the cleaning pipe 5, so as to sterilize the water body with the cleaning agent, maintain the stability of the water quality, and ensure the safety and reliability of the water supply.

[0038] In some implementations, reference continues. Figure 1The water supply equipment also includes a water quality testing device 6, which is located in the storage space 21 and connected to the water tank 2. The probe of the water quality testing device 6 extends into the storage space 21, or the device can be completely submerged within it, provided it is waterproofed. The connection method for the water quality testing device 6 can be bolted or welded, with no restrictions. The water quality testing device 6 is used to test water quality. It is electrically connected to a water quality cleaning device 4, which is suitable for releasing cleaning agents when the water quality is below a preset standard. The preset standard can be the turbidity and bacterial concentration of the water.

[0039] In some examples, the water quality testing device 6 includes a turbidity monitor, which is a device for continuously monitoring the turbidity in water. The online turbidity monitor typically uses optical measurement principles, such as a scattered light photometer or infrared light technology, to detect suspended particles in the water sample. When there are many suspended particles, the turbidity of the water increases. When the turbidity is greater than the preset turbidity, the water quality cleaning device 4 releases cleaning agent.

[0040] In other examples, the water quality testing device 6 includes an online microbial sensor placed in a water tank. The online microbial sensor uses a microbial electrode (such as a dissolved oxygen electrode or a fuel cell electrode) to detect the rate at which bacteria consume oxygen or produce electrons through metabolism, and converts this into a bacterial concentration signal to determine whether the bacterial concentration exceeds the standard. When the bacterial concentration exceeds the standard, the water quality cleaning device 4 releases a cleaning agent.

[0041] In this design, since the water supply equipment also includes a water quality detection device 6, when the water quality detection device 6 detects that the water quality is lower than the preset water quality, it will feed back a cleaning signal to the control module. The control module will then control the water quality cleaning device 4 to release cleaning agent to achieve automatic cleaning of the water body, reduce manual intervention, lower labor costs, and provide a fast response.

[0042] In some embodiments, the water purification device 4 includes an ozone generator 41, wherein the ozone generator 41 is an air source ozone generator 41. The air source ozone generator 41 extracts oxygen from the air and converts it into ozone through corona discharge. There is no need to add an additional oxygen source, and ozone can be prepared directly using air, which is low cost.

[0043] In some examples, the air-source ozone generator 41 includes a filter and a reaction chamber. The filter removes impurities such as dust and moisture from the air to prevent contamination of the discharge components. The air, after being treated by the filter, enters the reaction chamber and undergoes corona discharge under the action of a high-frequency, high-voltage electric field. The electric field energy breaks the chemical bonds of oxygen molecules, causing them to decompose into individual oxygen atoms. The free oxygen atoms quickly combine with the undecomposed oxygen molecules to form ozone molecules, which are then transported to the water tank 2 through the cleaning pipe 5.

[0044] In this design, since ozone cannot be stored for a long time, this application sets up an ozone generator 41 to produce ozone and then delivers the ozone to the storage space 21 of the water tank 2 to meet the sterilization requirements of the water body.

[0045] In some embodiments, the water cleaning device 4 further includes an ozone generator 42, which is disposed in the storage space 21 and connected to the water tank 2. One end of the cleaning pipe 5 is connected to the ozone generator 42, so that the ozone generated by the ozone generator 41 enters the ozone generator 42 through the cleaning pipe 5 and is then released into the water tank 2 through the ozone generator 42. The ozone generator 42 can increase the degree of mixing between ozone and water.

[0046] In some examples, the ozone emitter 42 is equipped with an ejector inside. After the ozone enters the ozone emitter 42, the ejector propels the ozone into the water at high speed, causing the ozone to break into tiny bubbles, thereby increasing the contact area between the ozone and the water.

[0047] In other examples, the ozone emitter 42 is equipped with an energy-releasing water pump, which drives the water to flow and form a circulating water flow, allowing ozone bubbles to diffuse evenly in the water, thus avoiding local ozone accumulation and insufficient contact between the water and ozone.

[0048] In this design, since the water cleaning device 4 also includes an ozone generator 42, the ozone generated by the ozone generator 41 enters the ozone generator 42 through the cleaning pipe 5 and is then released into the water tank 2 through the ozone generator 42. Therefore, the ozone can be fully mixed with the water through the ozone generator 42 to eliminate bacteria in the water and increase the water cleaning effect.

[0049] In some embodiments, the ozone generator 41 is connected to the water tank 2, and the connection method can be welding or bolting, etc., without limitation; or, the ozone generator 41 is connected to the support frame 1, and the connection method can be welding or bolting, etc., without limitation; or, the ozone generator 41 is connected to an external support structure, which can be a wall, and the ozone generator 41 and the wall can be bolted together.

[0050] In this design, the ozone generator 41 can be connected to the water tank 2; or the ozone generator 41 can be connected to the support frame 1; or the ozone generator 41 can be connected to the external support structure. This design can reduce the space occupied by the ozone generator 41 on the ground, thereby reducing the space occupied by the entire water supply equipment.

[0051] In some embodiments, the water supply equipment also includes an overflow pipe 7. The top end of the overflow pipe 7 is connected to a preset position on the top of the water tank 2. This preset position is close to the top of the water tank 2. The distance between the top end of the overflow pipe 7 and the top of the water tank 2 is not limited and can be designed according to actual needs. However, it should ensure that the water tank 2 has sufficient storage space 21 and that water does not overflow from the top of the water tank 2 before flowing into the overflow pipe 7. The top opening of the overflow pipe 7 is vertically upward and communicates with the storage space 21. When there is a large amount of water in the water tank 2 and it reaches a certain water level, the water can flow to the overflow pipe 7. The bottom end of the overflow pipe 7 passes through the side wall of the water tank 2 and communicates with the floor drain 10. Excess water will flow through the overflow pipe 7 to the floor drain 10 and then to the target location. This target location can be a sewage pipe or a storage tank, etc., without limitation.

[0052] In some examples, the bottom end of the overflow pipe 7 passes through the side wall of the water tank 2 and is directly connected to the floor drain 10. The water discharged through the bottom end of the overflow pipe 7 can flow directly to the floor drain 10, so as to achieve direct connection between the bottom end of the overflow pipe 7 and the floor drain 10.

[0053] In other examples, the bottom end of the overflow pipe 7 passes through the side wall of the water tank 2 and connects to the drainage space at the ground. The drainage space is connected to the floor drain 10, so that water flows through the overflow pipe 7 to the drainage space and then through the drainage space to the floor drain 10, thereby achieving an indirect connection between the bottom end of the overflow pipe 7 and the floor drain 10.

[0054] As can be seen, the connection method between the bottom end of the overflow pipe 7 and the floor drain 10 is not restricted and can be designed according to actual needs.

[0055] In this design, since the water supply equipment also includes an overflow pipe 7, when the water level in the water tank 2 is too high, the excess water will flow to the floor drain 10 through the overflow pipe 7, preventing water from overflowing from the top of the water tank 2, eliminating the risk of overflow, and ensuring the safety of the water supply equipment.

[0056] In some embodiments, the water supply equipment also includes a drain pipe 8, the top end of which is connected to the bottom of the water tank 2 and communicates with the storage space 21, so that the water in the storage space 21 can flow to the drain pipe 8. The bottom end of the drain pipe 8 passes through the top plate 12 and communicates with the floor drain 10, so that the drain pipe 8 can discharge the water to the floor drain 10, and then flow to the target location through the floor drain 10. The target location can be a sewage pipe or the like, without limitation.

[0057] In some examples, the bottom end of the drain pipe 8 passes through the top plate 12 and is directly connected to the floor drain 10. The water discharged from the bottom end of the drain pipe 8 can flow directly to the floor drain 10, so as to achieve direct connection between the bottom end of the drain pipe 8 and the floor drain 10.

[0058] In other examples, the bottom end of the drainage pipe 8 passes through the top plate 12 and connects to the drainage space at the ground. The drainage space is connected to the floor drain 10, so that water flows through the drainage pipe 8 to the drainage space and then through the drainage space to the floor drain 10, thereby achieving an indirect connection between the bottom end of the drainage pipe 8 and the floor drain 10.

[0059] As can be seen, the connection method between the bottom end of the drainage pipe 8 and the floor drain 10 is not restricted and can be designed according to actual needs.

[0060] In this design, since the water supply equipment also includes a drain pipe 8, when the water tank 2 is cleaned and sewage is discharged, the drain pipe 8 will be opened, and the sewage in the water tank 2 will be discharged to the floor drain 10 through the drain pipe 8, thereby increasing the convenience of sewage discharge.

[0061] In some embodiments, a drain valve is provided on the drain pipe 8 to control the opening and closing of the drain pipe 8. The drain valve can be a manual valve or an automatic valve, without limitation. When the drain valve is an automatic valve, the automatic valve is electrically connected to the control module so that the control module can control the opening and closing of the drain valve.

[0062] In some embodiments, the water supply equipment also includes a water inlet pipe 9, one end of which is connected to the water tank 2 and communicates with the storage space 21, and the other end of the water inlet pipe 9 is used to connect to a water source, which can be water stored in a water truck, etc., without limitation.

[0063] In this design, when the water level in the water tank 2 is too low, the pump can pump the water stored in the water truck into the water tank 2 through the water inlet pipe 9 to provide water to the water tank 2 and increase the convenience of water intake for the water tank 2.

[0064] In some embodiments, an inlet valve is provided on the water inlet pipe 9 to control the opening and closing of the water inlet pipe 9. The inlet valve can be a manual valve or an automatic valve, without limitation. When the inlet valve is an automatic valve, the automatic valve is electrically connected to the control module so that the control module can control the opening and closing of the inlet valve.

[0065] In some embodiments, the support frame 1 includes a plurality of legs 13, which are spaced apart at the bottom of the top plate 12 and connected to the top plate 12, and the plurality of legs 13 and the top plate 12 form an accommodating space 11.

[0066] In this design, the support frame 1 has a simple structure and can provide a stable support foundation. Meanwhile, the water pump 3 is placed in the accommodating space 11 formed by multiple support legs 13 and the top plate 12. The accommodating space 11 is large, and the staff can operate through the space between two adjacent support legs 13, which increases the convenience of installation and maintenance of the water pump 3.

[0067] In some implementations, pump 3 is a variable frequency pump, which can automatically adjust its speed according to the actual water consumption.

[0068] In this design, since water pump 3 is a variable frequency water pump, the variable frequency water pump can automatically adjust the speed according to the actual water consumption, thus avoiding providing too much or too little water supply, avoiding energy waste, and achieving constant pressure water supply.

[0069] In some examples, the variable frequency water pump is also equipped with a flow sensor and a display module. The flow sensor is located inside the variable frequency water pump to obtain the flow rate of the water being pumped. The flow sensor and the display module are electrically connected to display the water flow rate, allowing staff to visually observe the water flow situation.

[0070] In some examples, the variable frequency pump is also equipped with an operation panel that is electrically connected to the pump. The operation panel allows users to set parameters such as target pressure, upper / lower flow limit, speed range, and start / stop time, increasing the ease of use of the pump.

[0071] In some examples, the variable frequency pump is also equipped with an external power supply, which provides power to the variable frequency pump to meet its operating requirements.

[0072] In some examples, the variable frequency water pump is also equipped with a backup power supply, which is connected in parallel with the external power supply, so that the backup power supply and the external power supply can serve as backups for each other. When one of the backup power supply and the external power supply fails, the other of the backup power supply and the external power supply can be used to power the variable frequency water pump, ensuring the normal operation of the water supply equipment.

[0073] In some examples, the external power source and the backup power source are each equipped with solar panels to supplement the power of the external power source and the backup power source. By configuring solar panels, which are installed on the roof of the building, no additional land is required or other facilities need to be built. By setting up solar panels to supplement the power of the external power source and the backup power source, energy can be saved and energy consumption can be reduced, thus reducing electricity costs.

[0074] It is understandable that when the energy provided by the solar panels cannot meet the needs of the external power supply and backup power supply, external power supply equipment can be connected to supply power to the external power supply and backup power supply.

[0075] In some embodiments, the water tank 2 is cubic in shape, and the length, width and height of the water tank 2 are all 1.1-1.3m. In some examples, the length, width and height of the water tank 2 are all 1.2m.

[0076] In other embodiments, the water tank 2 is cubic in shape, with a length and height of 1.1-1.3m and a width of 1.9-2.1m. In some examples, the length and height of the water tank 2 are both 1.2m and the width of the water tank 2 is 2.0m.

[0077] As can be seen, the structural form of water tank 2 is not limited and can be designed according to actual needs.

[0078] In the description of the embodiments of this application, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0079] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
