Description

Technical Field

[0001] The utility model belongs to the technical field of dewatering and precipitation, and particularly relates to a dewatering and precipitation drainage metering device. Background Art

[0002] At present, precipitation wells are often used in the control of foundation pit groundwater. By reducing the groundwater volume through precipitation wells, it is convenient for foundation pit excavation. During the use of precipitation wells, accurate metering and statistics of the external drainage volume are necessary tasks. Therefore, a dewatering and precipitation drainage metering device is required.

[0003] Existing dewatering and precipitation drainage metering devices usually use water meters to record the drainage volume. However, during the use process, due to the small water output of the precipitation well, a large amount of gas is contained in the pipeline, and the water meter will be affected by the gas in the pipeline when recording the drainage volume, resulting in inaccurate recorded data. Secondly, there are many impurities in the groundwater, which causes the conventional water meter to stop rotating and the meter to be unclear in the short term, affecting the normal progress of the statistics of the external drainage volume of the precipitation well.

[0004] Therefore, we provide a dewatering and precipitation drainage metering device to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a dewatering and precipitation drainage metering device. Through the combined setting of an exhaust component and a filtering component, the problems that the dewatering and precipitation drainage metering device in the prior art will stop rotating and the meter will be unclear in the short term due to a large amount of gas in the pipeline and sediment impurities in the water are solved.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a dewatering and precipitation drainage metering device, including a box body, an exhaust component and a filtering component. The top of the box body is fixedly connected with an exhaust box, and the exhaust box and the box body are communicated through a conveying pipe. A valve is sleeved on the surface of the conveying pipe. The bottom of the left side of the box body is communicated with a water outlet pipe, and a water meter is sleeved on the surface of the water outlet pipe;

[0008] The exhaust component is arranged at the top of the exhaust box and includes an exhaust pipe. A mesh plate is arranged at the top of the exhaust pipe. A top rod is fixedly connected to the bottom of the mesh plate. The bottom of the top rod extends into the inner cavity of the exhaust box and is sleeved with a spring. A buoyancy plate is fixedly connected to the bottom of the top rod. A sealing ring is fixedly connected to the top of the buoyancy plate;

[0009] The filtering component is arranged in the inner cavity of the box body and includes a filter plate. A sludge discharge square pipe is communicated with the right side of the box body, and a waste storage box is communicated with the bottom of the sludge discharge square pipe. A motor is fixedly connected to the left side of the box body. The right side of the output end of the motor penetrates through the box body and is fixedly connected with a screw rod. A threaded sleeve is threadedly connected to the surface of the screw rod, and a scraper is fixedly connected to the bottom of the threaded sleeve.

[0010] The utility model is further arranged such that a liquid level gauge is fixedly connected to the left side of the exhaust box, and the probe on the right side of the liquid level gauge penetrates into the inner cavity of the exhaust box.

[0011] The utility model is further arranged such that a water injection pipe is communicated with the top of the right side of the exhaust box, and the bottom of the exhaust box is fixedly connected with the box body through a support column.

[0012] The utility model is further arranged such that sliding rails are fixedly connected to the front side and the rear side between the two sides of the inner cavity of the box body. Sliders are slidably connected to the inner cavities of the sliding rails, and the bottom of the slider is fixedly connected with the scraper.

[0013] The utility model is further arranged such that a triangular guide block is fixedly connected to the right side of the bottom of the inner cavity of the box body, and a bottom plate is fixedly connected to the bottom of the box body.

[0014] The utility model is further arranged such that a sewage discharge pipe is communicated with the bottom of the front side of the waste storage box, and a pipe cap is threadedly connected to the front side of the sewage discharge pipe.

[0017] The utility model has the following beneficial effects:

[0018] 1. Through the arrangement of the exhaust component of the utility model, when the water injection pipe conveys groundwater into the exhaust box, the gas will be directly discharged through the exhaust pipe and the mesh plate, and the water is stored in the exhaust box until the water level reaches the height of the liquid level gauge. At this time, the buoyancy plate drives the sealing ring to move upward until the sealing ring fits with the inner wall of the exhaust box, the exhaust pipe is blocked, and then the valve is opened. The water in the exhaust box enters the inner cavity of the box body through the conveying pipe, and the gas will not be conveyed into the box body, avoiding the influence of the gas on the measurement data of the metering water meter.

[0019] 2. With the provision of the filtration assembly in the present utility model, sediment in water is filtered by the filter plate. The motor is turned on, and the motor cooperates with the screw rod to drive the threaded sleeve and the scraper to move. The scraper moves to push the sediment filtered out on the top of the filter plate towards the sludge discharge square pipe. The sediment is pushed into the interior of the sludge discharge square pipe and then falls into the waste storage box. By cleaning the top of the filter plate, it can continuously carry out the filtration work, avoiding the influence of sediment in water on the measurement data of the metering water meter.

[0020] Of course, it is not necessary for any product implementing the present utility model to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the buoyancy plate 705 drives the sealing ring 706 to fit with the inner wall of the exhaust box 2 due to the buoyancy of the water, thereby realizing the blocking of the exhaust pipe 701. Subsequently, the valve 4 is opened, and the water inside the exhaust box 2 enters the box body 1 through the conveying pipe 3. The filter plate 801 in the box body 1 filters the sediment and impurities in the water. The filtered water is discharged through the water outlet pipe 5.
