Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial production technology, specifically to a device for detecting the flow rate of gravity-fed water. Background Technology
[0002] Many large factories and industrial parks face the challenge of collecting water from dispersed areas, such as rainwater and sewage. Large underground pipes are often used to collect this water. Real-time flow monitoring is difficult in these situations.
[0003] Adding a flow meter to the underground pipes can lead to problems. When the water flow is low, it may not be able to detect the flow. Conversely, reducing the pipe diameter can result in excessive instantaneous flow, causing drainage problems. A common method is to add a flow meter at the rear of the collection tank. However, this method has a drawback: the data obtained is significantly inaccurate due to the limited capacity of the collection tank itself. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a device for detecting the flow rate of gravity-flow water, enabling the calculation and monitoring of the flow rate, solving the problem of large detection errors in current conventional solutions, and facilitating inspection and recording.

[0010] Furthermore, the water collection tank is connected to an overflow pipe, which is connected to a pit, and the overflow pipe is also equipped with a second flow meter.
[0011] The advantage of adopting the above technical solution is that the overflow pipe prevents the entry of instantaneous large flow of water, the impact of extreme weather on flow monitoring, and discharges into the pit when the flow is too large.
[0012] Furthermore, the pit is equipped with a water outlet pipe, a first water pump is installed in the water outlet pipe, the water outlet pipe is connected to the top of the water collection tank, and a third flow meter is installed on the water outlet pipe.
[0013] The advantage of adopting the above technical solution is that the flow entering the pit is pumped back into the collection tank by the first water pump, and then discharged through the collection tank.
[0014] Furthermore, a second water pump is installed on the liquid outlet pipe, and the liquid outlet pipe is connected to a delivery pipe.
[0015] The advantage of adopting the above technical solution is that the second water pump is used to draw water from the collection tank and let it flow away through the delivery pipe, so as to keep the water in the collection tank continuously discharged.
[0016] Furthermore, the liquid inlet pipe is connected to a filtration device, including a filter box, which has a first filtration section and a second filtration section.
[0017] The advantage of adopting the above technical solution is that the installation of the filtration device avoids the blockage of the entire water supply pipeline by rainwater or industrial wastewater during long-term use.
[0018] Furthermore, the filter box is provided with an inlet and two outlets, and a partition plate is provided inside the filter box, which divides the entire filter box into a first filtration section and a second filtration section.
[0019] The advantage of adopting the above technical solution is that it has two filtration sections, so when one is cleaned, the other can be used.
[0020] Furthermore, the filter box is equipped with two insert plates for switching the working states of the first filter section and the second filter section.
[0021] The advantage of adopting the above technical solution is that the insertion plate is used to switch between the first filter section and the second filter section, which facilitates cleaning.
[0022] Furthermore, the filter box is provided with an openable top cover, and both the first filter section and the second filter section are provided with filter baskets, which are detachable and installable.
[0023] The advantage of adopting the above technical solution is that the detachable filter basket facilitates the cleaning of the entire filter box. During cleaning, it can be directly removed and then cleaned.
[0024] Furthermore, the level gauge is a hydrostatic level gauge.
[0025] The advantage of adopting the above technical solution is that the hydrostatic level gauge can be used to detect the amount of water in the water collection tank, and the water flow rate can be obtained by adding the amount of water discharged.
[0026] Furthermore, the liquid outlet pipe is equipped with multiple valves.
[0027] The advantage of adopting the above technical solution is that the valve is easy to install and maintain. Attached Figure Description

Detailed Implementation
[0034] The present invention will now be described in further detail with reference to the accompanying drawings.
[0035] like Figure 1 As shown, this utility model discloses a device for detecting the flow rate of gravity-fed water, comprising:
[0036] Liquid inlet pipe 1 can collect liquids from different locations by combining multiple pipes;
[0037] The water collection tank 2 is connected to the liquid inlet pipe 1 and also has a liquid outlet pipe 3;
[0038] The flow detection device includes a level gauge 4 located in the water collection tank 2 and a first flow meter 5 installed in the liquid outlet pipe 3. The level gauge 4 is a hydrostatic level gauge used to sense the amount of liquid in the water collection tank 2.
[0039] The advantages of adopting the above technical solution are that it enables real-time monitoring and detection of gravity flow rate, has a simple structure, small data deviation, low investment cost, and is easy to use.
[0040] The water collection tank 2 is connected to an overflow pipe 21, which is connected to a pit 6. The overflow pipe 21 is also equipped with a second flow meter 22. The top of the overflow pipe 21 is connected to the upper side wall of the water collection tank 2. When the water level in the water collection tank 2 reaches a certain position, water will flow out from the overflow pipe 21 into the pit 6 to avoid the phenomenon of excessive water damaging the water collection tank 2. At the same time, the overflow water volume is recorded by the second flow meter 22, so even if overflow occurs, it will not affect the flow detection.
[0041] Furthermore, the pit 6 is equipped with a water outlet pipe 61, and a first water pump 62 is installed on the water outlet pipe 61. The water outlet pipe 61 is connected to the top of the water collection tank 2, and a third flow meter 63 is installed on the water outlet pipe 61. Under normal flow conditions, the water in the pit 6 flows back into the water collection tank 2 to empty the pit 6 and make it convenient for use when the flow is too large next time. The returned water is measured by the third flow meter 63. When detecting the water flow, since the overflow has already been detected, this part of the water volume needs to be subtracted.
[0042] Furthermore, a second water pump 31 is installed on the outlet pipe 3, and the outlet pipe 3 is connected to a delivery pipe 32. Valves are installed on both sides of the second water pump 31. The valves can be ball valves and also have check valves. The delivery pipe 32 is connected to the lower side of the water collection tank 2. The second water pump 31 drives the water in the water collection tank 2 to be discharged. The flow rate is detected by the flow meter on the outlet pipe. The flow rate measured by the second flow meter 22 plus the flow rate detected by the liquid level gauge 4 in the water collection tank 2 is the flow rate entering the inlet pipe 1.
[0043] In some implementations, the inlet pipe 1 is connected to a filter device, such as... Figure 2-3 As shown, the system includes a filter box 7, which has a first filter section 71 and a second filter section 72. The first filter section 71 and the second filter section 72 are arranged side by side. The filter device plays a good filtering role, reducing impurities in rainwater and industrial wastewater, and effectively preventing blockage of water inlet pipes and water delivery pipes.
[0044] Furthermore, the filter box 7 is equipped with an inlet 73 and two outlets 74. A partition plate 75 is installed inside the filter box 7, dividing the entire filter box 7 into a first filtration section 71 and a second filtration section 72. The partition plate 75 is fixedly installed in the middle of the filter box 7, forming two filtration chambers, namely the first filtration section 71 and the second filtration section 72. The entire filter box 7 can be buried underground along with the liquid inlet pipe 1 and the water collection tank 2, without occupying above-ground space. A mounting plate similar to a manhole cover can be installed on the ground to cover the ground without affecting its use, and it can be opened for cleaning, etc.
[0045] In addition, the filter box 7 is equipped with two insert plates 76 for switching the working state of the first filter section 71 and the second filter section 72. The top of the insert plate 76 has a protrusion that can move up and down. This movement can be achieved by a cylinder or manual operation. They are located at the inlets of the first filter section 71 and the second filter section 72, respectively, switching their working state. When the insert plate 76 is opened upwards, water flows through the corresponding filter section. While water flows through one section, the other can be cleaned. A valve is also installed at the outlet 74 to cut off the water flow, keeping the filter section to be cleaned closed. After cleaning, the wastewater containing impurities can be extracted. To prevent leakage, multiple sealing rings are installed on the insert plate 76 and the filter box 7.
[0046] Furthermore, the filter box 7 is equipped with an openable top cover. Both the first filter section 71 and the second filter section 72 are equipped with filter baskets 77. The filter baskets 77 are detachable and installable. The top cover is connected to the filter box 7 via a hinge. After opening, the filter baskets 77 can be taken out from the filter box 7. The bottom and sides of the filter baskets 77 are filter screens, and the upper edge has a fixing strip. The filter box 7 is equipped with a step to receive the fixing strip. After installation, the fixing strip contacts the step. A certain space is left between the bottom of the filter baskets 77 and the filter box 7. The water outlet 74 is located on the side of the box body, below the filter box 7. The water flowing in through the water inlet 73 flows out after being filtered by the filter baskets 77. The filter baskets 77 have handles for easy handling. After handling, the impurities inside can be poured out and cleaned before being put back in.
[0047] Water flows into the collection tank 2 from the inlet pipe 1. The level gauge 4 in the collection tank 2 senses the water volume. At the same time, due to the limited capacity of the collection tank 2, the outlet pipe 3 continuously discharges the liquid. The first flow meter 5 senses the flow rate through the outlet pipe and the level gauge 4 senses the water volume in the collection tank 2.
[0048] Under normal circumstances, the total flow rate of the entire system can be obtained by calculating the cumulative flow rate of the liquid pipe (flow rate one) and the water volume in the collection tank 2 (flow rate two).
[0049] In the event of a large instantaneous water volume, water will overflow into the pit 6 through the overflow pipe 21. The second flow meter 22 will detect the flow as flow rate three. The sum of flow rate one, flow rate two and flow rate three is the total water flow.
[0050] If there is a return flow in the outlet pipe 61, the water volume detected by the third flow meter 63 at this time is flow rate four. The system flow rate at this time is the sum of flow rate one, flow rate two, and flow rate three minus flow rate four, which is the total flow rate. The first, second, and third flow meters can be ultrasonic flow meters, volumetric flow meters, and rotor flow meters, etc., selected according to actual usage needs.
[0051] The calculation interval can be set to 1 hour or 10 minutes to make the detection results more accurate. The detection results of each flow meter and level gauge 4 can be displayed on the monitor for easy viewing. The whole system occupies little space, has a compact design, and is fully functional.
[0052] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
