Description

Technical Field

[0001] This application relates to the field of water supply and drainage system technology, and in particular to a water-saving building water supply and drainage system. Background Technology

[0002] With the rapid pace of urbanization, water scarcity is becoming increasingly severe. Traditional building water supply and drainage systems suffer from numerous wasteful practices in their design and use, such as excessive water consumption for toilet flushing and ineffective utilization of rainwater. In recent years, with increased environmental awareness and technological advancements, water-saving water supply and drainage systems have gradually gained attention. Existing water-saving systems primarily reduce water waste by improving pipe design and adding water-saving devices, but some problems still exist in practical applications.

[0003] For related technology, please refer to Chinese Patent No. CN115571935B, which discloses a water supply and drainage system including a first box and a second box. The first box is fixedly installed on one side of the upper part of the second box. An inlet pipe is fixedly installed on one side of the upper part of the first box. A rotating rod is rotatably installed inside the first box. A first filter assembly is fixedly installed on the surface of the rotating rod. An impurity collection frame is fixedly installed inside the first box and on one side of the rotating rod. An impurity discharge mechanism is installed inside the impurity collection frame. A guide port is opened between the first box and the second box.

[0004] Regarding the aforementioned technologies, currently, all building water supply and drainage pipes are equipped with flow meters for monitoring flow. When staff need to record and count the flow of water supply and drainage in a building, they need to count according to the flow meter. The flow meter is usually installed in an underground shaft, but dust in the underground shaft easily falls onto the flow meter. Staff need to enter the underground shaft to wipe the flow meter, which results in low efficiency in recording and counting. Summary of the Invention

[0005] To improve the efficiency of record-keeping and statistics, this application provides a water-saving building water supply and drainage system.

[0006] This application provides a water-saving building water supply and drainage system, which adopts the following technical solution: A water-saving building water supply and drainage system includes a water supply pipe and a drainage pipe. The water supply pipe is equipped with a flow meter 1 for monitoring the flow rate of the water supply pipe, and the drainage pipe is equipped with a flow meter 2 for monitoring the flow rate of the drainage pipe. Above the flow meter 1 is a nozzle 1 for cleaning dust from the surface of the flow meter 1, and above the flow meter 2 is a nozzle 2 for cleaning dust from the surface of the flow meter 2. The nozzle 1 is connected to a connecting pipe for supplying water to the nozzle 1. The connecting pipe is connected to the nozzle 2. The connecting pipe is equipped with an on / off valve for opening or closing the connecting pipe. The end of the connecting pipe away from the nozzle 1 is connected to a water storage tank for storing rainwater.

[0007] By adopting the above technical solution, the water supply pipe supplies water to the building, and flow meter one monitors the flow rate in the water supply pipe. The drain pipe drains water to the outside of the building, and flow meter two monitors the flow rate in the drain pipe. When staff need to record and count the flow rates of the inlet and outlet pipes, they open the connecting pipe by opening and closing the valve. Water is then transported to nozzles one and two through the connecting pipe. Nozzle one cleans the surface of flow meter one, and nozzle two cleans the surface of flow meter two, thereby reducing the process of staff wiping flow meters one and two and improving the efficiency of recording and counting.

[0008] Optionally, the upper end of the water storage tank is connected to an inlet tank, the lower ends of the water storage tank and the inlet tank are connected, the upper surface of the inlet tank is at the same level as the ground, and the upper opening of the inlet tank is provided with a filter screen that is movably connected.

[0009] By adopting the above technical solution, rainwater enters the storage tank through the inlet tank, and the filter screen filters the rainwater, which helps to reduce the occurrence of blockage in the storage tank.

[0010] Optionally, a clamp is provided on one side of the water storage tank. The clamp is movably connected to the water storage tank. The clamp is horizontally positioned and located inside the water storage tank. A sponge layer is fixedly connected to one side of the clamp. The sponge layer is horizontally positioned. The end of the sponge layer away from the clamp is fixedly connected to the water storage tank. Both sides of the sponge layer abut against the water storage tank.

[0011] By adopting the above technical solution, after rainwater enters the water storage tank, the sponge layer absorbs the water, and some of the rainwater flows from the sponge layer into the water storage tank for storage due to gravity. The sponge layer helps to reduce water evaporation in the water storage tank, and at the same time, it performs secondary filtration on the water entering the water storage tank, reducing the occurrence of clogging of subsequent nozzles one and two.

[0012] Optionally, a push rod is fixedly connected to the side of the clamp away from the sponge layer. The push rod is set perpendicular to the clamp. One end of the push rod that passes through the water storage tank is provided with a driving component for driving the push rod to move laterally in the axial direction of the push rod. When the push rod moves laterally, the clamp squeezes the sponge layer.

[0013] By adopting the above technical solution, the driving component drives the push rod to move laterally, the push rod drives the clamping plate to move laterally, the clamping plate and the water storage tank squeeze the sponge layer, and then the water in the sponge layer flows into the bottom of the water storage tank. When the water in the water storage tank is used up, the water in the sponge layer can be used to replenish the water in the water storage tank, which helps to reduce the occurrence of the situation where there is no water in the water storage tank.

[0014] Optionally, the driving component includes a push rack, a transmission gear, and a rotating gear. One end of the push rack is fixedly connected to the push rod, the push rack is coaxially connected to the push rod, the transmission gear meshes with the push rack, and the transmission gear is coaxially connected to the rotating gear.

[0015] By adopting the above technical solution, when the sponge layer needs to be squeezed, the drive gear rotates, which in turn drives the transmission gear to rotate. The transmission gear drives the rack to move laterally, and the rack drives the push rod to move laterally, thus making the process of squeezing the sponge layer more convenient.

[0016] Optionally, a well channel is provided on one side of the rotating gear. The well channel is a cuboid, and flow meter one and flow meter two are both installed inside the well channel. A well opening is opened at the upper end of the well channel. A rotating rod is rotatably connected to the well opening of the well channel. A well cover is fixedly connected to the rotating rod. The rotating rod is set at one end of the well cover. A cam is coaxially connected to one end of the rotating rod. A sliding groove is opened on the side wall of the well channel. A linkage rack is vertically installed in the sliding groove. The linkage rack is vertically installed. One side of the linkage rack meshes with the rotating gear. As the well cover rotates with the rotating rod to be perpendicular to the ground, the cam drives the linkage rack to move downward. The linkage rack drives the rotating gear to rotate clockwise.

[0017] By adopting the above technical solution, flow meter 1 and flow meter 2 are installed inside the well, which facilitates the recording and statistics by the staff. When the staff opens the well cover, the well cover drives the rotating rod to rotate, the rotating rod drives the cam to rotate, the cam drives the linkage rack to descend, and the linkage rack drives the rotating gear to rotate. Thus, when the well cover is opened, the sponge layer is squeezed. When the water in the water tank is low, the water in the sponge layer is squeezed into the water tank during the process of opening the well cover, which makes it easier to clean flow meter 1 and flow meter 2.

[0018] Optionally, a return spring is fixedly connected to the end of the linkage rack away from the cam. The spring is vertically arranged, and the end of the spring away from the linkage rack is fixedly connected to the shaft.

[0019] By adopting the above technical solution, after the linkage rack descends, when the staff closes the manhole cover, the reset spring rebounds, which facilitates the reset of the linkage rack and makes it easier for subsequent use.

[0020] Optionally, a drive gear is rotatably connected inside the wellbore. The drive gear meshes with the side of the linkage rack away from the rotating gear. The drive gear is coaxially connected to the opening and closing valve. As the well cover rotates with the rotating rod to be perpendicular to the ground, the cam drives the linkage rack to move downward. The linkage rack drives the drive gear to rotate, and the drive gear drives the opening and closing valve to open the connecting pipe.

[0021] By adopting the above technical solution, when the staff opens the manhole cover, the connecting rack descends, driving the gear to rotate, which in turn opens the valve. During the process of opening the manhole cover, nozzle one and nozzle two clean the manhole, eliminating the need to wait for the cleaning process and further improving the efficiency of recording and statistics.

[0022] In summary, this application includes at least one of the following beneficial technical effects of water-saving building water supply and drainage systems: 1. By setting up spray head one and spray head two, the water supply pipe supplies water into the building, and flow meter one monitors the flow rate in the water supply pipe. The drain pipe drains water out of the building, and flow meter two monitors the flow rate in the drain pipe. When staff need to record and count the flow rates of the inlet and outlet pipes, they open the connecting pipe by opening and closing the valve. Water is then transported to spray head one and spray head two through the connecting pipe. Spray head one cleans the surface of flow meter one, and spray head two cleans the surface of flow meter two, thereby reducing the process of staff wiping flow meter one and flow meter two and improving the efficiency of recording and counting. 2. As the staff opens the manhole cover, the connecting rack descends, driving the gear to rotate and opening the valve. During the opening process, nozzles one and two clean the manhole, eliminating the need to wait for the cleaning process and further improving the efficiency of recording and statistics.

[0027] The present application will be further described in detail below with reference to all the accompanying drawings.

[0028] This application discloses a water-saving building water supply and drainage system.

[0029] Reference Figure 1 , Figure 2 and Figure 3A water-saving building water supply and drainage system includes a water supply and drainage mechanism 1, a water-saving mechanism 2, a cleaning mechanism 3, and a linkage mechanism 4. The water-saving mechanism 2 collects and utilizes rainwater, which helps to save water. The cleaning mechanism 3 cleans the water supply and drainage mechanism 1, which helps to reduce dust falling on the water supply and drainage mechanism 1. The linkage mechanism 4 links the water-saving mechanism 2 and the cleaning mechanism 3.

[0030] Reference Figure 1 , Figure 2 and Figure 3 The water supply and drainage mechanism 1 includes a water supply pipe 11, a drainage pipe 12, a flow meter 13, a flow meter 14, a well 15, a rotating rod 16, and a well cover 17. The water supply pipe 11 and the drainage pipe 12 are relatively parallel and horizontally arranged. The flow meter 13 is fixedly connected to the water supply pipe 11, and the flow meter 14 is fixedly connected to the drainage pipe 12. The well 15 is a cuboid. The flow meter 13 and the flow meter 14 are both arranged inside the well 15. The well 15 is vertically arranged and has a well opening at the upper end. The rotating rod 16 is rotatably connected to the well opening of the well 15. The rotating rod 16 is horizontally arranged and fixedly connected to one end of the well cover 17. The cross-sectional area of ​​the well cover 17 is equal to the cross-sectional area of ​​the well 15. The well cover 17 is movably connected to the well 15.

[0031] Reference Figure 1 , Figure 2 and Figure 3 Water supply pipe 11 supplies water to the building, and drainage pipe 12 drains the water out of the building. Flow meter 13 monitors the water flow in water supply pipe 11, and flow meter 24 monitors the water flow in drainage pipe 12. When the staff records and calculates the data of flow meter 13 and flow meter 24, the staff pulls the manhole cover 17, which rotates through the rotating rod 16. The staff enters the manhole 15 to observe and record the data of flow meter 13 and flow meter 24, which helps to reduce the risk of flow meter 13 and flow meter 24 being exposed and damaged.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The water-saving mechanism 2 includes an inlet tank 21, a storage tank 22, a filter screen 23, and a sponge layer 24. The inlet tank 21 is rectangular, and its upper surface is at the same level as the ground. The inlet tank 21 is vertically arranged and has an opening at its upper end. The filter screen 23 is detachably connected to the upper end of the inlet tank 21. The storage tank 22 is fixedly connected to the lower end of the inlet tank 21 and communicates with it. The sponge layer 24 is arranged inside the storage tank 22. One end of the sponge layer 24 is fixedly connected to the storage tank 22 and is horizontally arranged. Both sides of the sponge layer 24 abut against the storage tank 22. The sponge layer 24 is arranged at the upper end of the storage tank 22.

[0033] Reference Figure 1 , Figure 2 and Figure 3 Rainwater flows into the inlet tank 21 through the filter screen 23. The filter screen 23 filters the rainwater, which helps to reduce impurities entering the inlet tank 21. The rainwater flows into the storage tank 22 through the inlet tank 21. The sponge layer 24 further filters the rainwater, which facilitates the subsequent use of rainwater and saves water. At the same time, the sponge layer 24 absorbs water, which helps to reduce water vapor evaporation in the storage tank 22.

[0034] Reference Figure 1 , Figure 2 and Figure 3 The cleaning mechanism 3 includes a connecting pipe 31, a first nozzle 32, a second nozzle 33, and an on / off valve 34. The connecting pipe 31 is fixedly connected to the lower end of the water storage tank 22. The end of the connecting pipe 31 away from the water storage tank 22 passes through the well 15. Both the first nozzle 32 and the second nozzle 33 are fixedly connected to the connecting pipe 31 and are in communication with the connecting pipe 31. The on / off valve 34 is fixedly connected to the connecting pipe 31. The first nozzle 32, the second nozzle 33, and the on / off valve 34 are all located in the well 15. The first nozzle 32 is directly opposite the first flow meter 13, and the second nozzle 33 is directly opposite the second flow meter 14.

[0035] Reference Figure 1 , Figure 2 and Figure 3 When staff need to record and compile the values ​​of flow meter 13 and flow meter 24, they open the on / off valve 34. Water in the water storage tank 22 flows through the connecting pipe 31 to the nozzle 1 32 and nozzle 2 33. The nozzle 1 32 cleans the dust on the surface of flow meter 13, and the nozzle 2 33 cleans the dust on the surface of flow meter 24. This helps to reduce the need for staff to clean flow meter 13 and flow meter 2 14 and improves the efficiency of recording and compiling statistics.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The linkage mechanism 4 includes a cam 41, a linkage rack 42, a return spring 43, and a drive gear 44. The cam 41 is coaxially connected to the rotating rod 16. A groove is provided on the side wall of the shaft 15. The linkage rack 42 is slidably connected to the groove of the shaft 15. The linkage rack 42 is vertically arranged. The cam 41 abuts against the upper end of the linkage rack 42. The end of the linkage rack 42 away from the cam 41 is fixedly connected to the return spring 43. The end of the return spring 43 away from the linkage gear is fixedly connected to the shaft 15. The return spring 43 is vertically arranged. The drive gear 44 is arranged inside the shaft 15 and meshes with one side of the linkage rack 42. The drive gear 44 is rotatably connected to the shaft 15 and coaxially connected to the opening and closing valve 34.

[0037] Reference Figure 1 , Figure 2 and Figure 3When staff need to record and compile statistics on flow meters 13 and 14, they rotate the manhole cover 17. The cover 17 drives the rotating rod 16 to rotate, which in turn drives the cam 41. The cam 41 then moves the linkage rack 42 downwards, compressing the return spring 43. This, in turn, drives the gear 44 to rotate, simultaneously opening the opening / closing valve 34. This allows staff to clean flow meters 13 and 14 while opening the manhole cover 17, further improving recording and statistical efficiency without requiring any cleaning operations. After closing the manhole cover 17, the return spring 43 springs back, resetting the linkage rack 42. The rack 42 then drives the gear 44 to rotate, closing the opening / closing valve 34, thus facilitating continued use.

[0038] Reference Figure 1 , Figure 2 and Figure 3 The linkage mechanism 4 also includes a drive component 45, a push rod 46, and a clamping plate 47. The drive component 45 includes a push rack 451, a transmission gear 452, and a rotating gear 453. The rotating gear 453 meshes with the side of the linkage rack 42 away from the driving gear 44. The push rack 451 and the transmission gear 452 are set in the ground. The rotating gear 453 and the transmission gear 452 are coaxially connected. The transmission gear 452 meshes with the push rack 451. The transmission gear 452 is set above the push rack 451. The push rack 451 is set horizontally. The end of the push rack 451 away from the transmission gear 452 is fixedly connected to the push rod 46. The push rod 46 is coaxially connected to the push rack 451. The end of the push rod 46 that passes through the water storage tank 22 is fixedly connected to the clamping plate 47. The clamping plate 47 is set horizontally. The two ends of the clamping plate 47 are slidably connected to the two sides of the water storage tank 22. The side of the clamping plate 47 away from the push rod 46 is fixedly connected to one end of the sponge layer 24.

[0039] Reference Figure 1 , Figure 2 and Figure 3 Rainwater falls through the sponge layer 24 into the water storage tank 22. The sponge layer 24 absorbs water and reduces the rate of water evaporation in the water storage tank 22, thus facilitating the storage of rainwater. When the staff opens the manhole cover 17, the linkage rack 42 descends, which in turn drives the rotating gear 453 to rotate. The rotating gear 453 drives the transmission gear 452 to rotate, which in turn drives the push rack 451 to move laterally, which in turn drives the push rod 46 to move laterally. The push rod 46 drives the clamping plate 47 to squeeze the sponge layer 24, thereby squeezing out the water in the sponge layer 24. When the water in the water storage tank 22 is used up, the water is squeezed out by squeezing the sponge layer 24, which makes it easier to clean the flow meter 13 and flow meter 24.

[0040] The implementation principle of a water-saving building water supply and drainage system in this application embodiment is as follows: When staff need to record and count flow meters 13 and 14, they rotate the manhole cover 17. The manhole cover 17 drives the rotating rod 16 to rotate, which in turn drives the cam 41 to rotate. The cam 41 drives the linkage rack 42 to move downward, which in turn compresses the return spring 43. This causes the linkage rack 42 to drive the gear 44 to rotate, and simultaneously opens the opening and closing valve 34. This allows staff to clean flow meters 13 and 14 while opening the manhole cover 17, further improving the efficiency of recording and counting without requiring any cleaning operations.

[0041] When the staff opens the manhole cover 17, the linkage rack 42 descends, which in turn drives the rotating gear 453 to rotate. The rotating gear 453 drives the transmission gear 452 to rotate, which in turn drives the push rack 451 to move laterally, which in turn drives the push rod 46 to move laterally. The push rod 46 drives the clamping plate 47 to squeeze the sponge layer 24, thereby squeezing out the water in the sponge layer 24. When the water in the water storage tank 22 is used up, the water is squeezed out by squeezing the sponge layer 24, which makes it easier to clean the flow meter 13 and flow meter 24.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
