Abstract
Description
Technical Field
[0001] This utility model relates to auxiliary monitoring devices in the field of water conservancy and hydropower, and more particularly to a displacement device for operating underwater equipment. Background Technology
[0002] Most hydropower stations are currently equipped with underwater grab beams for opening and closing gates. During this process, foreign objects such as trees and rocks in the gate slot and sill can prevent the gate from reaching the bottom and sealing properly, causing difficulties for normal use and maintenance. Therefore, it is necessary to use underwater monitoring devices to observe the situation near the gate slot and sill so that any interference from foreign objects can be quickly detected and dealt with in a timely manner.
[0003] Current underwater monitoring equipment generally uses fixed underwater cameras, which are stationary in a specific location for monitoring. Because the camera positions are fixed and the monitoring area is limited, even multiple cameras cannot completely cover the gate's movement range. Therefore, in areas that cannot be observed, operators must visually observe the gate's movement and rely on experience to determine the location of any obstruction. This approach suffers from low accuracy in location determination, long processing times, and high costs. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a displacement device for operating underwater monitoring equipment. It solves the problems of low accuracy in determining the location of problems, long time consumption, and high cost caused by the fixed position or small monitoring range of underwater equipment in existing technologies.
[0005] According to an embodiment of this utility model, a displacement device for operating underwater equipment is provided, which is installed on an underwater grab beam. It includes a translation device, a telescopic platform, and a mechanical telescopic arm. The translation device is connected to the top of the mechanical telescopic arm via the telescopic platform, allowing the mechanical telescopic arm to move horizontally perpendicular to the translation device. The top of the mechanical telescopic arm is fixedly connected to the telescopic platform. The bottom of the mechanical telescopic arm is provided with several multi-functional mechanical interfaces, which move vertically along the bottom. Simultaneously, the telescopic platform and the mechanical telescopic arm move horizontally via the translation device.
[0006] In the above embodiments, the underwater camera and the mechanical gripper are installed at the lower end of the displacement device, which can drive the underwater camera and the mechanical gripper to move in the horizontal and vertical directions perpendicular to the translation device, effectively monitoring all directions of the gate. This solves the problem in the prior art that underwater equipment has a fixed position or a small monitoring range, resulting in low accuracy in judging the location of the problem, long cycle time and high cost.
[0007] Furthermore, the multi-functional mechanical interface at the bottom of the mechanical telescopic arm can be connected to devices including underwater cameras, mechanical grippers, magnetic suction devices, and scrapers.
[0008] Furthermore, the translation device includes a base, a sliding rail, and a translation trolley; the base is connected to the grab beam, so that the entire translation device and the grab beam perform lifting actions synchronously; the sliding rail is connected to the base and is in the horizontal direction; the translation trolley is connected to the telescopic platform, driving the telescopic platform and the mechanical telescopic arm to move on the sliding rail.
[0009] Furthermore, the telescopic platform has a pyramid structure and is telescopic, with its larger end connected to the translation device and its smaller end connected to the mechanical telescopic arm.
[0010] Furthermore, the mechanical telescopic arm includes a first structure and a second structure. The first structure is connected to the telescopic platform by a pivot pin, and the second structure is also connected to the first structure by a pivot pin, so that the angle between the first structure and the telescopic platform is adjustable, and the angle between the first structure and the second structure is adjustable.
[0011] Furthermore, the translation trolley is detachably connected to the mechanical telescopic arm.
[0012] Furthermore, the mechanical telescopic arm includes a first structure and a second structure. The first structure is for telescopic movement, allowing it to move vertically. The second structure is for mounting various monitoring devices.
[0013] Furthermore, the first and second structures of the mechanical telescopic arm are fixed together by a pivot pin.
[0014] Furthermore, the second structure of the mechanical telescopic arm is made of metal, and various mechanical or electrical structures are provided at the lower end. Welding operations can also be performed on the second structure.
[0015] Furthermore, multiple translation trolleys and mechanical telescopic arms can be installed on the translation device.
[0016] Furthermore, the translation device can be equipped with multiple translation trolleys and robotic arms, and long scrapers can be installed to scrape off stains on the gate.
[0017] Furthermore, a magnetic suction device can also be installed at the lower end of the mechanical telescopic arm for picking up underwater metal devices.
[0018] Furthermore, the base of the displacement device is not detachable from the sliding track, while the translation trolley and the mechanical telescopic arm are detachable.
[0019] Furthermore, the translation track is installed on the grab beam or at the lifting lugs at both ends of the grab beam's lifting point, forming a horizontally placed translation track.
[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] This invention utilizes a displacement device to assist various underwater monitoring devices in mobile monitoring. Compared to previous fixed monitoring methods, it offers greater flexibility. Furthermore, when monitoring is not required for extended periods, the translation trolley and mechanical telescopic arm can be detached and installed on another underwater grab beam requiring monitoring. The device can move horizontally and vertically perpendicular to the translation mechanism, allowing it to be moved to various parts of the gate. The displacement device enables various underwater devices to move horizontally or vertically, allowing for omnidirectional movement of underwater equipment and achieving comprehensive monitoring, thus improving monitoring efficiency and expanding the monitoring range. Therefore, it solves the problems of low accuracy in locating underwater equipment due to fixed positions or limited monitoring ranges, as well as the long time cycles and high costs associated with existing technologies.
