Description

Technical Field

[0001] This utility model belongs to the technical field of anti-seepage wall detection device, and more specifically, it relates to a device for detecting the bottom condition of anti-seepage wall of hydraulic dam. Background Technology

[0002] A cutoff wall is a continuous wall constructed in loose permeable layers or earth-rock dams to prevent seepage. Due to its reliable structure, good seepage prevention effect, adaptability to various geological conditions, simple construction, and low cost, it is particularly effective in addressing seepage deformation hazards such as dam foundation leakage, downstream "soil erosion," and "piping." It has been widely used both domestically and internationally. In my country, cutoff walls are generally the first choice for seepage prevention treatment of water conservancy and hydropower overburden layers and earth-rock cofferdams with seepage pressure. Chinese Patent No. CN202120967951.1 discloses a device for detecting the bottom condition of a cutoff wall in a water conservancy dam, including a base plate. A connecting frame is fixedly connected to the upper surface of the base plate. A guide rod is movably connected to the upper surface of the base plate. A threaded rod is movably connected to the upper surface of the base plate. A threaded sleeve is movably connected to one side of the threaded rod. A drilling rig is fixedly connected to one side of the threaded sleeve. A first rack is fixedly connected to one side of the drilling rig, and the first rack meshes with a second disc gear. A drain tank is fixedly connected to the upper surface of the base plate. This invention not only enables the device to automatically pour waterproofing liquid into the wall through the cooperation of the plug and the socket, improving the convenience of the device, but also allows the temperature of the waterproofing liquid in the discharge tank to be detected by a temperature sensor, making it convenient for staff to observe. Furthermore, it can prevent the waterproofing liquid from flowing into the discharge pipe when the device is not in use by controlling the valve, thus improving the flexibility of the device.

[0003] Based on the above, the inventors have discovered the following problems: When the equipment in the above patent is used, it can automatically pour concrete. However, in the above device, the anti-seepage liquid needs to be introduced into the opening through the drain pipe. Therefore, the drain pipe needs to be located above the opening. The opening is formed by the work of the drill rod, so the diameter of the drill rod and the diameter of the opening are almost the same. The drill rod may damage the drain pipe when it is working.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a device for detecting the bottom condition of the seepage prevention wall of a hydraulic dam, in order to achieve a more practical purpose. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a device for detecting the bottom condition of the anti-seepage wall of a hydraulic dam, thereby resolving the issue that current detection devices may damage the discharge pipe during use.

[0006] The purpose and effectiveness of this utility model, a device for detecting the bottom condition of a seepage-proof wall in a hydraulic dam, are achieved through the following specific technical means:

The fixing plate is connected through the liquid outlet pipe, and a through hole is formed on the surface of the connecting plate.

[0009] Furthermore, the drilling mechanism includes a pair of mounting plates mounted on a mounting platform. A motor is mounted on the surface of one mounting plate, and a connecting rod is mounted through the output end of the motor through the mounting plate. The end of the connecting rod away from the motor output end is connected to the other mounting plate. A first bevel gear is mounted on the surface of the connecting rod. The mechanism also includes a threaded rod and a guide rod mounted on the surface of the mounting platform. A second bevel gear is mounted on one end of the threaded rod, and the second bevel gear meshes with the first bevel gear. The threaded rod and the guide rod pass through a moving block. A drilling rig is mounted on one end of the moving block, and a drill rod is mounted on the output end of the drilling rig. The mechanism also includes an opening in the surface of the mounting platform, located directly below the drill rod.

[0010] Furthermore, a protective shell is installed on the surface of the mounting plate on which the motor is installed.

[0012] Furthermore, the liquid discharge tank is made of stainless steel.

[0013] Furthermore, a rubber pad is installed at the bottom of the mounting platform.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model utilizes the combined use of a water pump outlet pipe, a liquid extraction pipe, and a mechanism for moving the outlet pipe. In use, the device is first placed in a suitable position, then the drilling mechanism is activated to drill a hole. After drilling, the electric cylinder is activated, which moves the connecting plate, which in turn moves the fixing plate, thus moving the outlet pipe above the drilled hole. It should be noted that the outlet pipe is made of flexible tubing and has a certain length. Then, the water pump is activated, injecting the anti-seepage liquid from the discharge tank into the hole. Through this design, the outlet pipe can be kept away from the drilling mechanism during use, thus preventing damage to the outlet pipe from the drilling mechanism and improving practicality.

[0029] Example:

[0030] As attached Figure 1 To be continued Figure 4 As shown:

[0031] This utility model provides a device for detecting the bottom condition of the anti-seepage wall of a hydraulic dam, including an installation platform. The surface of the installation platform is equipped with an opening mechanism and a liquid discharge tank. The surface of the liquid discharge tank is equipped with a water pump. The surface of the water pump is equipped with an outlet pipe and a suction pipe. The suction pipe extends into the interior of the liquid discharge tank. The surface of the installation platform is equipped with a mechanism for moving the outlet pipe.

[0032] The mechanism for moving the liquid outlet pipe includes an electric cylinder mounted on the surface of the mounting platform. A connecting plate is mounted on the output end of the electric cylinder, and a fixing plate is mounted on the surface of the connecting plate. The fixing plate is connected through the liquid outlet pipe, and a through hole is formed on the surface of the connecting plate.

[0033] By using a combination of a water pump outlet pipe, a liquid extraction pipe, and a mechanism for moving the outlet pipe, the device is first placed in a suitable position. Then, the drilling mechanism is activated to drill a hole. After drilling, the electric cylinder is activated, which moves the connecting plate, which in turn moves the fixing plate, thus moving the outlet pipe above the drilled hole. It should be noted that the outlet pipe is made of flexible tubing and has a certain length. Then, the water pump is activated, which injects the anti-seepage liquid from the discharge tank into the hole. Through the above design, the outlet pipe can be kept away from the drilling mechanism during use, thereby avoiding damage to the outlet pipe by the drilling mechanism and improving practicality.

[0034] The drilling mechanism includes a pair of mounting plates mounted on a mounting platform. A motor is mounted on the surface of one mounting plate, and a connecting rod is mounted through the output end of the motor through the mounting plate. The end of the connecting rod away from the motor output end is connected to the other mounting plate. A first bevel gear is mounted on the surface of the connecting rod. The mechanism also includes a threaded rod and a guide rod mounted on the surface of the mounting platform. A second bevel gear is mounted on one end of the threaded rod, and the second bevel gear meshes with the first bevel gear. The threaded rod and the guide rod pass through a moving block. A drilling rig is mounted on one end of the moving block, and a drill rod is mounted on the output end of the drilling rig. The mechanism also includes an opening on the surface of the mounting platform, which is located directly below the drill rod.

[0035] By using the drilling mechanism, when drilling is required, the motor and drill can be started. The motor starts and drives the connecting rod to rotate, which in turn drives the first bevel gear to rotate. The first bevel gear then drives the second bevel gear to rotate, which in turn drives the threaded rod to rotate. The threaded rod then drives the moving block to move, which in turn drives the drill to move downward. The drill starts and drives the drill rod to rotate, thus performing the drilling operation. The guide rod can limit the movement of the moving block.

[0036] The mounting plate on which the motor is installed is covered with a protective shell. The first bevel gear and the second bevel gear are located inside the protective shell. The end of the guide rod away from the mounting platform is connected to the bottom of the protective shell.

[0037] The use of a protective case can protect the internal components.

[0038] The liquid discharge tank has an injection port on its surface, and a sealing cap is installed on the surface of the injection port.

[0039] The filling port allows for easy addition of anti-leakage fluid to the drain tank, while the sealing cap prevents contamination of the liquid inside the drain tank.

[0040] The liquid discharge tank is made of stainless steel.

[0041] Using stainless steel can extend the service life of the drain tank.

[0042] The mounting platform is equipped with a rubber pad at its bottom. The use of the rubber pad increases the friction between the mounting platform and the ground.

[0043] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
