Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, and in particular to a levee breach sealing device for water conservancy dam projects. Background Art

[0002] Levee breach sealing devices used in water conservancy and dam projects refer to special equipment and materials used to quickly and effectively seal gaps or damaged parts of levees or dams caused by floods or other natural disasters. These sealing devices include sandbag filling devices, inflatable retaining walls, prefabricated modular retaining devices, etc. The purpose of designing such devices is to prevent water from penetrating the levee and carrying away sediment, leading to the occurrence of pipe bursts.

[0003] However, during the use of the existing device, on the one hand, because it is mainly used for the reinforcement and seepage protection of dams, it is necessary to determine the location of the dam seepage pipe burst before use. The location of the dam seepage pipe burst requires personnel to patrol the dam and cooperate with the release of chemicals to detect the location of the dam pipe burst. During the inspection, the dam is small and the abnormal seepage water surface is not easy to observe. The water flow rate of the river channel during the flood season is fast and the amount of chemical release is large, which is not suitable for ecological protection. As a result, when the existing dam breach sealing device is used, it is inconvenient to use the pressure difference caused by the abnormal water flow rate when the underwater seepage pipe bursts on the inner slope of the dam to conduct chemical release detection at the abnormal point to determine the location of the pipe burst. On the other hand, when the existing dam breach sealing device is used to underwater reinforce the inner slope of the dam at the pipe burst, personnel need to cooperate with large-scale machinery and equipment to drive a certain number of sand retaining boards into the river channel and then release reinforcement materials. When the large-scale equipment is not dispatched in time, the existing device is not convenient for providing personnel with a manual and easy-to-install platform for the water surface sand retaining boards to quickly carry out subsequent reinforcement operations on the dam.

[0031] Example 1: Please refer to Figures 1 to 4 and Figures 8 to 11The present invention provides a technical solution: a levee breach sealing device for water conservancy dam projects, wherein a steering seat 2 is installed on both sides of a machine body 1, a propeller 3 is connected to the inner side of the steering seat 2 through a motor, the front and rear sides of the upper end of the machine body 1 are rotatably connected to an organic plate 4 through bearings, and a No. 1 electric push rod 5 is movably connected to the lower side of the machine plate 4, and the No. 1 electric push rod 5 is fixed to the bottom of the installation cabin 6, the installation cabin 6 is opened on the inner side of the machine body 1, and a material box 7 is installed on the right side of the bottom of the installation cabin 6, a mounting frame 8 is provided at the bottom opening of the installation cabin 6, and a mounting ring 9 is provided on the outer side of the mounting frame 8, and the mounting ring 9 is fixed to the bottom of the machine body 1. A baffle 10 is provided on the rotating sleeve in the groove outside the mounting ring 9, and a detection assembly 11 is slidably provided in the mounting frame 8. The detection assembly 11 includes a sleeve 111, which is slidably mounted on the inner side of the mounting frame 8. A pressure sensor 112 is connected to the top of the sleeve 111 through a spring. A movable body 113 is movably mounted in the hole groove inside the sleeve 111. The movable body 113 is designed to be a spherical structure. The hole groove inside the sleeve 111 corresponds to the spherical structure of the movable body 113. The inner side of the sleeve 111 is designed to be a hollow structure. A bottom column 114 is installed at the lower end of the movable body 113. The detection assembly 11 is used for pipe burst detection of the dam;

[0032] The closing assembly 12 is arranged between the detection assembly 11 and the material box 7. The closing assembly 12 includes a mounting box 121, which is fixed to the lower ends of the front and rear sides of the mounting frame 8. The upper ends of the two mounting boxes 121 are connected to the inner cavity of the material box 7 through pipes. The bottom of the inner side of the two mounting boxes 121 is connected to a sliding plug 122 by a spring sliding connection. A protrusion is designed on the inner side between the two sliding plugs 122. The position of the protrusion of the sliding plug 122 corresponds to the active position of the sliding sleeve 111.

The extension assembly 13 is arranged on the inner side of the machine plate 4. The extension assembly 13 is used to facilitate the insertion of the sand baffle after it is expanded.

[0033] When the propeller 3 pushes the body 1 to conduct underwater inspection of the inner slope of the river embankment, when a pressure difference caused by suspected seepage pipe burst appears underwater on the inner slope of the embankment, the sleeve 111 moves downward in the mounting frame 8 due to the pressure difference, so that the pressure spring resistance between the sleeve 111 and the pressure sensor 112 is reduced, and the control system will record the position where the pressure sensor 112 changes vertically. At the same time, through the cooperation of the sleeve 111 and the closing component 12, the chemical detection agent in the material box 7 is released into the water area of the abnormal point of the embankment through the discharge hole 123, and cooperates with personnel to inspect the back slope of the abnormal embankment point and the chemical detection of accumulated water to determine the position of the seepage pipe burst, and cooperates with the baffle 10 and the mounting ring 9 to avoid the influence of underwater floating objects on the detection of the detection component 11.

A closing component 12 is provided between the detection component 11 and the material box 7. The closing component 12 is used for the delivery of chemicals in the material box 7;

[0035] The extension assembly 13 is arranged on the inner side of the machine plate 4. The extension assembly 13 includes two mounting cavities 131. The two mounting cavities 131 are opened on the left and right inner sides of the machine plate 4. A plurality of extension plates 132 are stacked and slidably arranged inside the mounting cavities 131. A rack 133 is installed at the bottom of the extension plate 132. A gear plate 134 is engaged at the lower end of the rack 133. The gear plate 134 is fixed in the mounting cavity 131 by a motor. A plurality of slot blocks 135 are installed at the upper end of the extension plate 132. A connecting rod 136 is fixed on one side of the extension plate 132. Block 136, the extension plates 132 slidingly arranged in the left and right installation cavities 131 are arranged oppositely. The inner side of the extension plates 132 in the left and right installation cavities 131 is the installation end of the connecting block 136. A connecting groove 137 is opened on the other side of the extension plate 132. The two extension plates 132 are connected by the concave-convex matching of the connecting block 136 and the connecting groove 137. The two slot blocks 135 on the extension plate 132 are used for inserting the sand guard plate. The extension component 13 is used to facilitate the insertion of the sand guard plate after being unfolded.

[0036] When large equipment cannot be deployed in time, the propeller 3 is used to quickly move the machine body 1 to the abnormal area, and the machine plate 4 is opened by the No. 1 electric push rod 5. Then, by starting the gear plate 134 motor, the extension plate 132 is unfolded to the left and right sides of the machine plate 4. The operator manually inserts the sand retaining plate through the slot block 135 into the preset position on the riverbed and fixes it.

[0037] Working principle: When using the dike breach sealing device for water conservancy dam projects, the operator first puts the body 1 into the river. After the body 1 is put into the water, the sliding sleeve 111 floats in the water due to its hollow structure, and drives the movable body 113 and the bottom column 114 to move upward in the mounting frame 8. At the same time, the pressure sensor 112 detects that the resistance of the connection spring between the sliding sleeve 111 increases. At this time, the control system records the initial value of the pressure sensor 112. Then the operator opens the pipeline valve on one side of the material box 7 and turns on the thruster 3 through the control system. Then, the thruster 3 is turned on through the control system. The steering seat 2 controls the body 1 to inspect for pipe bursts and leakage in the river channel near the embankment. When the body 1 is inspecting the river channel, the shield 10 rotates on the mounting ring 9 due to the interference of the water flow direction or floating objects such as underwater garbage, and blocks the rotation transfer to reduce the impact on the sliding sleeve 111, the movable body 113 and the bottom column 114. At the same time, when some water plants interfere with and hang on the bottom column 114, the circumferential movement of the bottom column 114 in the sliding sleeve 111 through the movable body 113 will not affect the position of the sliding sleeve 111, thereby improving the accuracy and range of detection of the pressure sensor 112;

[0038] During the inspection process, when pipe bursts and leakages occur in the dam, abnormal vortices appear in the flow velocity and direction of the water body under the river channel on the inner slope of the dam. At this time, the pressure difference caused by the flow velocity in the water body under the river channel drives the bottom column 114, the movable body 113 and the sliding sleeve 111 to move downward in the mounting frame 8. At this time, the pressure sensor 112 detects that the resistance of the spring below is reduced, and the control system records the data and records the position through the positioning system. At the same time, when the sliding sleeve 111 moves downward on the mounting frame 8, it will resist and drive the sliding plug 122 to move downward synchronously in the mounting box 121. After the sliding plug 122 moves, the chemical agent in the material box 7 flows into the mounting box 121 through the pipeline and is released into the water through the discharge hole 123. After that, the operator checks the back slope of the dam through the abnormal dam inspection positioning point sent by the system, and uses chemical detection to check whether there is pipe burst or leakage in the back slope water or water area.

[0039] In the above process, after the inspectors have determined through chemical testing that there is a seepage pipe burst at the abnormal location of the dam, the operator controls the steering seat 2 and the propeller 3 through the control system to move the machine body 1 to the abnormal location of the dam, and moves the No. 1 electric push rod 5 on the open side upward to expand the machine plate 4 by 90 degrees. Then, the gear disc 134 motors in the installation cavities 131 on the left and right sides are opened, and the extension plates 132 in the two installation cavities 131 on the left and right sides are driven to move and expand to the left and right sides through the gear disc 134 and the rack 133. When the extension plates 132 When the connecting groove 137 moved to one side corresponds to the position of the connecting block 136, the upper extension plate 132 moves downward so that the connecting groove 137 is mounted on the connecting block 136. At this time, the gear plate 134 motor continues to rotate to drive the extension plate 132 to move until only one extension plate 132 is left in the installation cavity 131. Then the operator inserts the sand retaining plate into the bottom of the river channel through the slot block 135, and reinforces the inner slope of the dam by placing sandbags or anti-seepage reinforcement materials in the area between the sand retaining plate and the dam to prevent pipe bursts from causing dam breaches.
