Description

Technical Field

[0001] This utility model relates to the field of water supply engineering technology, and in particular to water supply equipment. Background Technology

[0002] Water supply and drainage generally refer to urban water supply systems and drainage systems (building water supply and drainage). Among them, water supply projects are projects that supply domestic and industrial water to residents and enterprises, as well as fire-fighting water, road greening water, etc. It consists of water source, water intake structure, raw water pipeline, water treatment plant and water supply network. It has the function of collecting and transporting raw water and improving water quality. In domestic and industrial water use, the variable frequency constant pressure water supply system uses the network water pressure (or user water flow) as the set parameter. Through microcomputer control of the frequency converter output frequency, the speed of water pump motor is automatically adjusted to realize the closed-loop regulation (PID) of network water pressure, so that the water supply system automatically and stably maintains the set pressure value.

[0003] However, in the current constant pressure variable frequency water supply equipment connected to the external water supply network, the equipment and pipelines are connected as one unit. When the filter pipe is blocked, it is not convenient to disassemble and clean it. At the same time, when cleaning is required, the equipment needs to be shut down, which will affect the user's water supply. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an intelligent constant pressure variable frequency water supply device that allows for the disassembly and cleaning of the filter tube while ensuring water supply to users during the cleaning process. This solves the problems of inconvenient disassembly and cleaning when the filter tube is clogged, and the need to shut down the equipment for disassembly and cleaning, which affects users' water supply.

[0005] This utility model provides the following technical solution: an intelligent constant pressure variable frequency water supply device, including a mounting plate. A water pump unit is fixedly mounted on the front side of the upper surface of the mounting plate. A drain pipe is fixedly mounted on the front end of the water pump unit. An output pipe is fixedly mounted on the upper end of the drain pipe. A butterfly valve is provided in the middle of the front end of the drain pipe. A fixing frame is fixedly mounted on the rear side of the upper surface of the mounting plate. A water tank is fixedly mounted on the upper end of the fixing frame. A connecting pipe is fixedly connected to the bottom end of the water tank. A pressure tank is provided on the left side of the upper surface of the mounting plate. The output end of the pressure tank is connected to a flow meter. A flow meter is fixedly mounted on the upper end of the circumferential surface of the output pipe. A control cabinet is provided on the right side of the upper surface of the mounting plate. A filter pipe is movably mounted on the left end of the output pipe. A branch pipe is fixedly connected to the front side of the circumferential surface of the left end of the output pipe.

[0006] Furthermore, the output pipe is equipped with switch valves at both ends of the filter pipe and at the inlet of the branch pipe. A filter is installed inside the filter pipe. Movable grooves are formed at both ends of the filter pipe, and connecting blocks are movably installed in these grooves. A sleeve is fixedly connected to the end of the connecting block away from the filter pipe, and a sealing pipe is threaded into the sleeve. Limiting blocks are symmetrically fixedly installed on the upper and lower sides of the interior of both ends of the filter pipe. Sliding grooves are formed on the upper and lower sides of the circumferential surface of the sealing pipe at the end near the filter pipe, and the limiting blocks are movably installed in these grooves. A flow meter installed on the output pipe monitors the water flow rate. When the filter pipe becomes blocked, causing a decrease in water flow and thus failing to meet water demand, the operator opens the switch valve at the inlet of the branch pipe and closes the switch valves at both ends of the output pipe near the filter pipe. Then, the operator removes the filter pipe for cleaning by rotating the sleeve in the reverse direction, thus ensuring the water supply needs are met.

[0007] Furthermore, a connecting ring is threaded to the end of the sleeve away from the filter tube, and the end of the connecting ring away from the sleeve abuts against the side wall of the output tube. By threading a connecting ring to the end of the sleeve away from the filter tube, the filter tube can be installed more stably in the output tube.

[0008] Furthermore, filter screens are symmetrically installed inside the branch pipe, and sewage pipes are fixedly installed at the front ends of the left and right sides of the branch pipe. The filter screens installed inside the branch pipe can ensure the safety of people's water supply.

[0009] Compared with the prior art, the advantages of this utility model are as follows:

[0010] 1. The staff connects the equipment to the external water supply network and installs a flow meter on the output pipe to monitor the water flow. When the filter pipe becomes blocked, causing the water flow to decrease and fail to meet the water demand, the staff opens the valve at the inlet of the branch pipe and closes the valves at both ends of the output pipe near the filter pipe. Then, the staff rotates the sleeve in the reverse direction, allowing the sleeve and the sealing tube to be retracted into the filter pipe along the slide groove. When the sealing tube is retracted into the filter pipe, the filter pipe is removed for cleaning. Water is then transported from the branch pipe to ensure that the water supply equipment can be used normally to supply water to users during the removal and cleaning of the filter pipe. When the water demand is too high, the valves on the output pipe and branch pipe are opened to allow water to flow out from the filter pipe and branch pipe, increasing the water flow. At the same time, the pressure tank is activated to pressurize the water to ensure water supply.

[0011] 2. The filter screen installed inside the branch pipe can reduce impurities in the water during use, thereby increasing water safety. When the filter screen becomes clogged, the switch valve installed on the drain pipe can be opened to backwash the filter screen through the drain pipe, thus ensuring the normal use of the filter screen.

A water pump unit 2 is fixedly mounted on the front side of the upper surface of the mounting plate 1. A drain pipe 3 is fixedly mounted on the front end of the water pump unit 2. An output pipe 4 is fixedly mounted on the upper end of the drain pipe 3. A butterfly valve 5 is provided in the middle of the front end of the drain pipe 3. A fixing frame 6 is fixedly mounted on the rear side of the upper surface of the mounting plate 1. A water tank 7 is fixedly mounted on the upper end of the fixing frame 6. A connecting pipe 8 is fixedly connected to the bottom end of the water tank 7. A pressure tank 9 is provided on the left side of the upper surface of the mounting plate 1. The output end of the pressure tank 9 is connected to a flow meter 10. A flow meter 10 is fixedly mounted on the upper end of the circumferential surface of the output pipe 4. A butterfly valve 5 is provided on the right side of the upper surface of the mounting plate 1. The system includes a control cabinet 11, a filter pipe 12 movably installed at the left end of the output pipe 4, and a branch pipe 13 fixedly connected to the front side of the left circumferential surface of the output pipe 4. The operator fixes the water pump unit 2 onto the mounting plate 1, then connects the water pump unit 2 and the output pipe 4 through the drain pipe 3. The water tank 7 is then connected to the water pump unit 2 via connecting pipes 8. Finally, the external water supply network is connected to the output pipe 4 to provide domestic and industrial water. The water pump unit 2 controls the water consumption at different times, thereby saving water resources. When water consumption is too high and the water pump unit 2 cannot adjust it, the pressure tank 9 is used to increase the pressure, thus meeting the user's water demand.

[0019] In this embodiment, switch valves 14 are respectively installed on the output pipe 4 near the left and right ends of the filter pipe 12 and the inlet end of the branch pipe 13. A filter 15 is installed inside the filter pipe 12. Movable grooves are opened at the left and right ends of the filter pipe 12, and connecting blocks 17 are movably installed in the movable grooves. A sleeve 16 is fixedly connected to the end of the connecting block 17 away from the filter pipe 12. A sealing pipe 18 is threadedly connected inside the sleeve 16. Limiting blocks 19 are symmetrically fixedly installed on the upper and lower sides inside the left and right ends of the filter pipe 12. Sliding grooves 20 are opened on the upper and lower sides of the circumferential surface of the sealing pipe 18 near the filter pipe 12, and the limiting blocks 19 are movably installed in the sliding grooves 20. A flow meter 10 on the output pipe 4 monitors the water flow in the output pipe 4. When the filter pipe 12 becomes blocked, causing the water flow to decrease and thus failing to meet the water demand, the operator opens the switch valve 14 at the inlet end of the branch pipe 13 and closes the switch valves 14 at both ends of the output pipe 4 near the filter pipe 12. Then, the operator rotates the sleeve 16 in the reverse direction, allowing the sleeve 16 to carry the sealing tube 18 along the slide groove 20 to be retracted into the filter pipe 12. When the sealing tube 18 is retracted into the filter pipe 12, the filter pipe 12 is removed for cleaning. At the same time, water is transported from the branch pipe 13 to meet people's water demand.

[0020] In this embodiment, a connecting ring 21 is threaded to the end of the sleeve 16 away from the filter tube 12, and the end of the connecting ring 21 away from the sleeve 16 abuts against the side wall of the output tube 4. By threading the connecting ring 21 to the end of the sleeve 16 away from the filter tube 12, the length of the filter tube 12 can be adjusted by rotating the connecting ring 21, thereby making the filter tube 12 more stably installed in the output tube 4.

[0021] In this embodiment, filter screens 22 are symmetrically installed inside the branch pipe 13, and drain pipes 23 are fixedly installed at the front ends of the left and right sides of the branch pipe 13. The filter screens 22 installed inside the branch pipe 13 can reduce impurities in the water during the use of the branch pipe 13, thereby increasing the safety of people's water use. At the same time, when the filter screen 22 becomes blocked, the drain pipes 23 can be used to backwash the filter screen 22, thereby ensuring the normal use of the filter screen 22.

[0022] Working principle: The operator fixes the water pump unit 2 on the mounting plate 1, then connects the water pump unit 2 and the output pipe 4 through the drain pipe 3. The water tank 7 is then connected to the water pump unit 2 through the connecting pipe 8. Finally, the external water supply network is connected to the output pipe 4 to provide domestic and industrial water. The water pump unit 2 controls the water consumption at different times, thus saving water resources. When water consumption is too high and the water pump unit 2 cannot regulate it, the pressure tank 9 increases the pressure, raising the water flow rate. Simultaneously, a flow meter 10 is installed on the output pipe 4 to monitor the water flow. When the filter pipe 12 becomes blocked, causing water flow... When the water level drops and cannot meet the water demand, the staff will open the valve 14 at the inlet of branch pipe 13 and close the valves 14 at both ends of the output pipe 4 near the filter pipe 12. Then, the staff will rotate the sleeve 16 in the opposite direction, allowing the sleeve 16 and the sealing tube 18 to be retracted into the filter pipe 12 along the slide groove 20. When the sealing tube 18 is retracted into the filter pipe 12, the filter pipe 12 will be removed for cleaning. At the same time, water will be transported from the branch pipe 13. When the water demand is too high, the valves 14 will be fully opened, allowing water to flow out from the filter pipe 12 and the branch pipe 13 to meet the user's water demand.
