Description

Technical Field

[0001] This utility model relates to the field of water conservancy project operation and management technology, specifically to a rubber dam filling and drainage device. Background Technology

[0002] Rubber dams are a new type of hydraulic structure that emerged with the development of polymer synthetic materials. They are bag-shaped dams formed by inflating the material with water through filling and draining pipelines. The dam crest is secure, and the dam height can be adjusted as needed to control the upstream water level, thereby providing benefits such as irrigation and flood control. Therefore, rubber dams are widely used in water conservancy projects.

[0003] Chinese Patent (Application No. 2014202538692) discloses a rubber dam filling and drainage device, belonging to a rubber dam bag filling and drainage equipment. It includes a water supply pipe, one end of which is connected to the rubber dam, and the other end to a water collection tank. A first valve is installed on the water supply pipe. The water supply pipe also includes three parallel loops: the first loop has a first water pump, a first check valve, and a second valve connected in series; the second loop has a second water pump, a second check valve, and a third valve connected in series; the third loop has a fourth valve; the third loop is connected to the first loop between the first check valve and the second valve; the third loop is connected to the second loop between the second check valve and the third valve; and a fifth valve is installed at the end of the third loop that connects to the first loop. The advantages of this utility model are: low cost, compact structure, simple construction, replaceable water pumps, simple maintenance, and reduced pump house construction costs. However, this rubber dam filling and drainage system is still somewhat cumbersome for small dams; and because filling the rubber dam bag requires certain water quality requirements, a dedicated water purification device is needed.

[0004] To address the problems of the aforementioned solutions, patent document CN207159929U discloses a rubber dam filling and drainage device. During dam raising, the filling valve is closed, the drain valve is opened, and the water pump is started. Silt and sewage at the bottom of the collection well are pumped out and discharged through the drain valve and drain pipe. After the silt and sewage are completely removed, the water flowing out of the drain pipe is clean water. The drain valve remains closed, the filling valve and overflow valve are opened, and the drain valve is closed. Water flows through the main pipeline into the dam bag, completing the filling process. Excess water flows out through the overflow valve and overflow pipe. The filling valve and overflow valve are then closed, completing the dam bag filling. During dam lowering, an extended handle installed in the pipe well is used to operate the drain valve. Water in the dam bag is discharged through the drain pipe until the dam bag collapses, completing the lowering process. The drain valve is then closed. During operation, this device can drain the lower layer of sewage from the collection well, thus ensuring the quality of the water entering the rubber dam. However, the water introduced into the rubber dam generally comes from river channels, and after prolonged use, sediment tends to accumulate inside the dam. During dam collapse, when the water is drained, the sediment deposited inside the dam cannot be effectively removed. Therefore, further optimization of the existing rubber dam filling and drainage system is necessary. Utility Model Content

[0005] The main purpose of this utility model is to provide a rubber dam filling and drainage device that can ensure the water quality entering the rubber dam and flush out the sediment deposited in the rubber dam during the process of injecting water into the rubber dam.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: A rubber dam filling and drainage device includes a water collection tank, a submersible pump installed at the lower end of the water collection tank, the outlet of the submersible pump connected to a water supply pipe, the water supply pipe connected to the water inlet of the rubber dam body, a drain pipe fixedly connected to the water supply pipe, a first electric valve and a first water quality turbidity sensor installed on the drain pipe, a second electric valve installed on the water supply pipe downstream of the drain pipe, the first water quality turbidity sensor, the first electric valve, a first controller and the second electric valve electrically connected, an overflow pipe fixedly connected to the water supply pipe downstream of the second electric valve, a pressure limiting valve installed on the overflow pipe, a pressure sensor installed inside the rubber dam body, the pressure sensor electrically connected to the pressure limiting valve via a third controller, a drain pipe fixedly connected to the outlet of the rubber dam body, a drain valve installed on the drain pipe, a branch pipe provided on one side of the drain pipe, the two ends of the branch pipe fixedly connected to the drain pipes on the front and rear sides of the drain valve respectively, a third electric valve and a second water quality turbidity sensor installed on the branch pipe, the third electric valve, the second water quality turbidity sensor and the second controller electrically connected.

[0007] Specifically, the first electric valve is a normally open electric valve, the second electric valve is a normally closed electric valve, and the third electric valve is a normally closed electric valve.

[0008] Specifically, a filter seat is fixed in the water collection tank above the submersible pump. The outer edge of the filter seat is fixedly connected to the inner wall of the water collection tank. The middle part of the filter seat has an upward conical protrusion to form a guide cone. The filter seat outside the guide cone is recessed downward to form an annular cavity. The lower end of the vertical part of the water inlet bend is located in the water collection tank. The vertical part of the water inlet bend is concentric with the guide cone. Water in the river enters the water collection tank through the horizontal and vertical parts of the water inlet bend.

[0009] Specifically, a filter basket is placed inside the annular cavity. The filter basket is circular, with its outer and inner sides bent upwards, and the filter basket is located in the annular cavity.

[0010] Specifically, two vertical lifting rods are fixed inside the filter basket, with the upper end of the lifting rods fixedly connected to an upper rod located above the water inlet bend.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By linking the normally open first electric valve with the normally closed second electric valve, and in conjunction with the first water quality turbidity sensor, automatic sewage discharge is achieved during the initial water filling stage. When the first water quality turbidity sensor detects that the water in the sewage pipe is clear, the first controller immediately closes the sewage valve and opens the water injection valve to ensure that only clean water is injected into the dam body, thus preventing siltation from the source.

[0012] 2. Utilizing the water pressure during filling, the sediment deposited inside the dam is forced to be discharged through the branch pipe, at which point the third electric valve opens. The second water quality turbidity sensor monitors the water quality in the branch pipe in real time. After the sediment is discharged, the branch pipe valve automatically closes, achieving a coordinated operation of filling and dredging, reducing the frequency of manual maintenance.

[0013] 3. When the pressure inside the dam exceeds the threshold, the pressure sensor triggers the pressure relief valve to open, releasing pressure through the overflow pipe to prevent the rubber dam from bursting due to overfilling. In an emergency, the second controller can be shut off, and clean water can be injected directly, balancing safety and operational flexibility.

[0014] 4. The guide cone design forces water flow diffusion, preventing debris accumulation and guiding impurities into the annular filter basket. The upward-bending structure on both the inner and outer sides of the filter basket effectively intercepts suspended solids while preventing impurities from escaping. The combination of the lifting rod and the upper rod design facilitates the removal of debris from the filter basket, significantly reducing maintenance costs.

[0015] 5. The first controller is dedicated to switching the water quality during water injection; the second controller is responsible for drainage and dredging; and the third controller independently monitors the dam pressure. Each subsystem operates independently and collaboratively, achieving unattended operation throughout the entire process of water filling, sewage discharge, dredging, and pressure maintenance.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1: Refer to Figure 1 As shown, a rubber dam filling and drainage device includes a water collection tank 1. A submersible pump 2 is installed in the lower end of the water collection tank 1. The outlet of the submersible pump 2 is connected to a water supply pipe 3. The water supply pipe 3 is connected to the water inlet of the rubber dam body 11. A sewage pipe 4 is fixedly connected to the water supply pipe 3. A first electric valve 5 and a first water quality turbidity sensor 6 are installed on the sewage pipe 4. The first electric valve 5 is a normally open electric valve. A second electric valve 8 is installed on the water supply pipe 3 behind the sewage pipe 4. The second electric valve 8 is a normally closed electric valve. The first water quality turbidity sensor 6, the first electric valve 5, the first controller 7, and the second electric valve 8 are electrically connected.

[0022] An overflow pipe 9 is fixedly connected to the water supply pipe 3 on the rear side of the second electric valve 8, and a pressure limiting valve 10 is installed on the overflow pipe 9. A pressure sensor 18 is installed inside the rubber dam body 11, and the pressure sensor 18 is electrically connected to the pressure limiting valve 10 through a third controller 19.

[0023] The outlet of the rubber dam body 11 is fixedly connected to the drainage pipe 12. A drainage valve 13 is installed on the drainage pipe 12. A branch pipe 14 is provided on one side of the drainage pipe 12. Both ends of the branch pipe 14 are fixedly connected to the drainage pipes 12 on the front and rear sides of the drainage valve 13, respectively. A third electric valve 15 and a second water quality turbidity sensor 17 are installed on the branch pipe 14. The third electric valve 15 is a normally closed electric valve. The third electric valve 15, the second water quality turbidity sensor 17, and the second controller 16 are electrically connected.

[0024] When water needs to be added to the rubber dam body 11, the submersible pump 2, the first controller 7, the second controller 16, and the third controller 19 are activated. After the second controller 16 is activated, the third electric valve 15 opens, and the submersible pump 2 transports water from the collection tank 1 to the water supply pipe 3. Since the first electric valve 5 is a normally open electric valve and the second electric valve 8 is a normally closed electric valve, after the submersible pump 2 is activated, the sewage in the lower end of the collection tank 1 enters the water supply pipe 3 and is discharged through the sewage pipe 4. Water from the river enters the collection tank 1 through the water inlet bend 106 to replenish it. At the same time, the first water quality turbidity sensor 6 monitors the water quality in the sewage pipe 4 in real time. When the water in the sewage pipe 4 becomes clear, the first water quality turbidity sensor 6 sends a signal to the first controller 7, which opens the second electric valve 8 and closes the first electric valve 5. At this time, the submersible pump 2 adds water from the collection tank 1 to the rubber dam body 11 through the water supply pipe 3.

[0025] After the water in the water inlet pipe 3 enters the rubber dam body 11, the water in the rubber dam body 11 is discharged through the drain pipe 12 and the branch pipe 14. During the process of the water entering the rubber dam body 11 being discharged from the branch pipe 14, the sediment deposited in the rubber dam body 11 can be flushed out.

[0026] When water in the rubber dam body 11 is discharged through the branch pipe 14, the second water quality turbidity sensor 17 monitors the water quality in the branch pipe 14 in real time. When the water in the branch pipe 14 becomes clear, the second water quality turbidity sensor 17 sends a signal to the second controller 16, and the second controller 16 closes the third electric valve 15. The water discharged from the water supply pipe 3 can then remain in the rubber dam body 11.

[0027] When water is stored in the rubber dam body 11, the pressure sensor 18 monitors the pressure inside the rubber dam body 11 in real time. When the pressure inside the rubber dam body 11 exceeds the set threshold in the third controller 19, the third controller 19 opens the pressure limiting valve 10, and the water in the water supply pipe 3 is discharged through the overflow pipe 9 to avoid excessive water being added to the rubber dam body 11.

[0028] When it is necessary to quickly inject water into the rubber dam body 11, the submersible pump 2, the first controller 7, and the third controller 19 are activated. At this time, the second controller 16 is closed, the third electric valve 15 remains closed, and the sewage in the lower end of the water collection tank 1 is discharged from the sewage pipe 4. Then, the clear water in the water collection tank 1 is injected into the rubber dam body 11.

[0029] Example 2: Based on Example 1, referring to... Figure 2 and Figure 3As shown, a filter seat is fixed in the water collection tank 1 above the submersible pump 2. The outer edge of the filter seat is fixedly connected to the inner wall of the water collection tank 1. The middle part of the filter seat has an upward conical protrusion to form a guide cone 102. The filter seat outside the guide cone 102 is recessed downward to form an annular cavity 101. The lower end of the vertical part of the water inlet bend 106 is located in the water collection tank 1. The vertical part of the water inlet bend 106 is concentric with the guide cone 102. Water in the river enters the water collection tank 1 through the straight part and the vertical part of the water inlet bend 106.

[0030] A filter basket 103 is placed inside the annular cavity 101. The filter basket 103 is circular, with its outer and inner sides bent upwards. The filter basket 103 is located in the annular cavity 101.

[0031] Two vertical lifting rods 104 are fixed inside the filter basket 103. The upper end of the lifting rod 104 is fixedly connected to the upper rod 105, which is located above the water inlet bend 106.

[0032] During the process of the water diversion bend 106 introducing water from the river channel into the water collection tank 1, the water discharged from the outlet of the water diversion bend 106 into the water collection tank 1 can be dispersed by the guide cone 102. By setting the guide cone 102, it is possible to prevent debris from accumulating on the guide cone 102 and to force the debris in the water into the filter basket 103, thus ensuring the effective filtration area of ​​the filter seat and effectively filtering the water in the water collection tank 1. This prevents water shortage in the water collection tank 1 below the filter seat and ensures the efficiency of water injection into the rubber dam body 11.

[0033] When it is necessary to clean the debris in the filter basket 103, the filter basket 103 is pulled upward by the upper rod 105 and the lifting rod 104. When the filter basket 103 is close to the upper end of the water collection tank 1, the impurities in the filter basket 103 can be easily removed.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
