Description

Technical Field

[0001] This utility model relates to the field of dam safety monitoring technology, and in particular to a drainage pipe interface device for a water pipe type settling meter. Background Technology

[0002] In accordance with the overall requirements of the Ministry of Water Resources for the construction of smart water conservancy, and focusing on the main tasks of water conservancy project operation management, supervision and management, and collaborative management, a digital platform for water conservancy project operation management will be built using digital means such as the Internet of Things, big data, and artificial intelligence. This will fully realize the intelligent and modern operation management of water conservancy projects, further ensure the safe operation of water conservancy projects, and give full play to the benefits of water conservancy projects.

[0003] Hydraulic structures, under the influence of their own materials, will deform due to the consolidation of soil and the rheological properties of rockfill. Excessive deformation can lead to defects such as uneven settlement and cracks. Therefore, monitoring facilities need to be deployed during dam construction. Deformation monitoring mainly includes: dam surface deformation, internal deformation of the dam (foundation), deformation of the seepage barrier, deformation of the spillway, and deformation of the surrounding rock of underground caverns. The monitoring instruments and their installation for internal dam (foundation) deformation should comply with relevant national and industry technical specifications. In a horizontally layered layout, a combination of water-tube settlement meters and tension wire horizontal displacement meters is recommended. Water-tube settlement meters are used to monitor the vertical displacement of the dam, while tension wire horizontal displacement meters are used to monitor the horizontal displacement. The settlement heads and pipelines of the water-tube settlement meters and the anchor plates and pipelines of the tension wire horizontal displacement meters should be installed in excavated trenches during dam filling, and their installation should comply with relevant specifications.

[0004] A water-tube settling meter is a high-precision measuring device used for long-term, automated monitoring of the vertical displacement (settlement or uplift) of the ground surface, building foundations, or embankments (such as dams and roadbeds). Its core working principle utilizes the principle of communicating vessels to correlate the changes in liquid level at a reference point with the changes at multiple monitoring points, thereby calculating the settlement at each monitoring point. Therefore, water-tube settling meters are widely used in the field of internal deformation monitoring for dam safety and can also achieve automated monitoring.

[0005] like Figure 1The diagram shows the engineering installation of a water-tube settling meter. Water in the tank flows into a connecting pipe through a pipeline. One end of the connecting pipe extends to the settling probe at the reference point, and the other end extends to the monitoring point and connects to the measuring tube. A measuring scale (measuring plate) is installed at the monitoring point to observe and measure the liquid level in the measuring tube. A drain pipe and an vent pipe are installed inside the settling probe. The vent pipe is used to expel air from the connecting pipe, and the drain pipe is used to discharge excess liquid that overflows into the probe due to liquid level fluctuations. The outlet of the drain pipe is connected to a water collection device. When settling occurs at the monitoring point, the liquid level drops, and water in the connecting pipe flows into the settling probe and is discharged through the drain pipe.

[0006] However, in the industry, the monitoring and maintenance of water tube settling meters has always been quite complicated. The most important issue is: during the monitoring process of water tube settling meters, it is difficult to determine when the readings are accurate, especially for water tube settling meters that have been installed for a long time. It is difficult to determine which measuring point is usable and which measuring point is malfunctioning.

[0007] Therefore, this case is brought. Utility Model Content

[0008] The purpose of this utility model is to provide a drainage pipe interface device for a water pipe type sedimentation meter to solve the above-mentioned technical problems.

[0009] To achieve the above objectives, the technical solution of this utility model is as follows: A drain pipe interface device for a water pipe type sedimentation meter includes: A transparent rigid pipe, inside which a waterwheel that can be driven to rotate by water flow is installed; The progressive tube includes an inlet progressive tube and an outlet progressive tube, which are respectively installed at both ends of a transparent rigid tube, and the diameter of the progressive tube gradually decreases from the side closer to the transparent rigid tube to the side farther away from the transparent rigid tube. The inlet hose and outlet hose are provided. One end of the inlet hose is installed on the inlet progressive tube, and the other end is used to connect to the outlet of the water pipe sedimentation meter. One end of the outlet hose is installed on the outlet progressive tube, and the other end is used to connect to the water collection device of the water pipe sedimentation meter.

[0010] Furthermore, the waterwheel includes a column and several waterwheels, the waterwheels being rotatably connected to the column via bearings, and the two ends of the column being fixedly connected to the inner wall of the transparent rigid pipe via mounting seats.

[0011] Furthermore, the waterwheel is shaped like a spoon.

[0012] Furthermore, the inlet hose and outlet hose are made of nylon tubing.

[0013] Furthermore, cameras are used to determine whether the waterwheel inside the transparent rigid pipe is rotating.

[0014] Furthermore, the waterwheel is red.

[0015] The advantages of this utility model are: 1. The observation principle of a water-tube settling meter is simple; the observation results depend on the stability of the water column in the measuring tube and the absence of air bubbles. This solution adds an interface device with integrated visual monitoring function to the outlet section of the water-tube settling meter's drain pipe. The device contains a transparent rigid pipe with a brightly colored (e.g., red) waterwheel inside. When water flows through the drain pipe, the waterwheel rotates. Observers or a camera can visually determine the drainage and fluid flow at the measuring point by observing whether the waterwheel rotates, thus confirming whether the currently measured data is stable and accurate. This design effectively solves the problem of determining "when the reading is valid" during long-term operation of a water-tube settling meter.

[0016] 2. This scheme involves adding an interface device to the outlet section of the drainage pipe of the water-tube settling meter. If the waterwheel inside the device rotates stably during the settlement process, it indicates that the water flow characteristics inside the drainage pipe are stable, indicating that the measuring point is intact. If uneven settlement of the dam body causes the drainage pipe to rupture or become blocked, the drainage pipe will not be able to discharge water, and the waterwheel will not rotate. This proves that the settlement measuring head (point) is in a failed state, and the data from this measuring point cannot be used for the evaluation of the dam's safe operation status.

[0017] 3. By installing sensors on fixed cameras or waterwheel pillars, the timing of automated measurement data acquisition is determined by comprehensively judging the operating status of the waterwheel, further ensuring the accuracy of the water-tube settling meter data.

[0018] 4. This solution has a simple structure, low cost, and convenient installation. It can be matched with any type of water pipe sedimentation meter without requiring large-scale modification of the original system, which to a certain extent broadens the applicability of the equipment.

[0020] The present invention will be further described in detail below with reference to the embodiments. It should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicated by the accompanying drawings are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0021] This embodiment proposes a drainage pipe interface device for a water-tube type sedimentation meter, such as... Figure 2 As shown, the device is installed at the outlet of the drain pipe of the water-tube sedimentation meter. Figure 3 As shown, the interface device includes a transparent rigid tube 6, a progressive tube, an inlet hose 1, and an outlet hose 7.

[0022] A waterwheel, propelled by water flow, is installed inside a transparent rigid pipe 6. The size of the transparent rigid pipe 6 can be customized, but good visibility must be ensured so that the rotation of the waterwheel can be determined by the human eye or a camera. The waterwheel includes a column 5 and multiple waterwheel wheels 4. The waterwheel wheels 4 are rotatably connected to the column 5 via bearings. The upper and lower ends of the column 5 are fixedly connected to the inner wall of the transparent rigid pipe 6 via an upper mounting seat 3 and a lower mounting seat 9, respectively. The waterwheel can be made of plastic, but the color should be bright to facilitate observation by workers or machine vision. Red is recommended in this embodiment. Preferably, the column 5 is installed in the middle area of ​​the transparent rigid pipe 6, and the waterwheel is installed in the middle position of the column 5. The four wheels of the waterwheel are shaped like scoops to facilitate the capture of weak water flow, causing the waterwheel to rotate with the water flow.

[0023] Preferably, this embodiment also includes a camera (not shown in the figure) for observing the operating status of the waterwheel and for determining the acquisition time of the automated data of the water-tube settling meter, thereby further ensuring the accuracy of the water-tube settling meter data.

[0024] The progressive tube includes an inlet progressive tube 2 and an outlet progressive tube 8, which are respectively installed at both ends of the transparent rigid tube 6. The diameter of the progressive tube gradually decreases from the side closer to the transparent rigid tube 6 to the side farther away from the transparent rigid tube 6. The material and size of the progressive section are determined according to the actual requirements of the specific project, and it is necessary to ensure good sealing after connection to prevent water leakage from the drain pipe.

[0025] The inlet hose 1 and outlet hose 7 can be made of soft nylon tubing, which can adapt to drainage pipes of different diameters and achieve a good seal to prevent water leakage from the drainage pipe. One end of the inlet hose 1 is installed on the inlet progressive tube 2, and the other end is used to connect to the outlet of the water-tube sedimentation meter. One end of the outlet hose 7 is installed on the outlet progressive tube 8, and the other end is used to connect to the water collection device of the water-tube sedimentation meter.

[0026] refer to Figure 2 During the settling process, water overflowed from the outlet of the connecting water pipe located inside the settling probe, and the overflowed water was discharged through the drain pipe. (Reference) Figure 3 Water entering the drain pipe passes through the inlet hose 1 and the inlet progressive pipe 2 in sequence before entering the transparent rigid pipe 6. As the water flows through the transparent rigid pipe, the waterwheel rotates with the water flow. Afterward, the water flows through the outlet progressive pipe 8 and the outlet hose 7 in sequence before entering the water collection device of the drain pipe for recycling.

[0027] The observation principle of a water-tube settling meter is simple; the observation results depend on the stability of the water column in the measuring tube and the absence of air bubbles. This solution adds an interface device with integrated visual monitoring to the outlet section of the water-tube settling meter's drainage pipe. The device contains a transparent rigid pipe (6) and a brightly colored (e.g., red) waterwheel. When water flows through the drainage pipe, the waterwheel rotates. Observers or a camera can visually determine the drainage and fluid flow at the measuring point by observing whether the waterwheel rotates, thus confirming whether the measured data is stable and accurate. This effectively solves the problem of determining "when the reading is valid" during long-term operation of the water-tube settling meter. If the waterwheel rotates stably during settlement, it indicates stable water flow characteristics inside the drainage pipe, indicating that the measuring point is intact. If uneven settlement of the dam causes the drainage pipe to rupture or become blocked, water cannot flow from the drainage pipe, and the waterwheel will not rotate. This proves that the settlement probe (point) is in a failed state, and the data from this point cannot be used to evaluate the dam's safe operation.

[0028] This solution is simple in structure, low in cost, and easy to install. It can be matched with any type of water pipe sedimentation meter without requiring large-scale modification of the original system, thus broadening the applicability of the equipment to a certain extent.

[0029] The above embodiments are only used to explain the concept of the present invention, and are not intended to limit the protection of the present invention. Any non-substantial modifications made to the present invention using this concept should fall within the protection scope of the present invention.
