Description

Technical Field

[0001] This utility model relates to the technical field of crack detection equipment, specifically a crack detection device for hydraulic structures. Background Technology

[0002] Hydraulic structures, such as dams, sluices, and dikes, are subjected to complex hydrological environments and mechanical forces over long periods, making them highly susceptible to cracking. These cracks not only affect the structural safety and stability of hydraulic structures but can also lead to serious problems such as leakage, thereby threatening the lives and property of people in the surrounding areas and the balance of the ecological environment.

[0003] Currently, various devices and methods for crack detection in hydraulic structures have emerged on the market. Among them, the method of using a movable platform to mount a measuring instrument is relatively common. A Chinese utility model patent (publication number: CN222977765U) discloses a crack detection device for hydraulic structures. This device includes a movable platform on which a measuring instrument for crack detection is mounted; an angle adjustment mechanism mounted on the movable platform to adjust its tilt angle; and a lifting mechanism connected to the movable platform to raise and lower it. This design, by adjusting the tilt angle of the movable platform through the angle adjustment mechanism, thereby changing the measuring angle of the measuring instrument, can adapt to the crack detection needs of hydraulic structures to a certain extent.

[0004] However, in practical applications, existing crack detection equipment still has significant limitations. While existing measuring instruments can change the tilt angle, they struggle to flexibly adjust the horizontal rotation angle when dealing with complex and varied hydraulic structures. Hydraulic structures have diverse shapes and layouts, and cracks may appear in various locations and angles. For example, on some curved dam structures or hydraulic structures with complex geometries, tilt angle adjustment alone cannot accurately align the measuring instrument with the cracks for detection. This necessitates frequent repositioning of the entire detection equipment by operators during actual inspections to adjust the instrument's horizontal orientation, increasing the workload and difficulty of the inspection, reducing efficiency, and affecting the accuracy and precision of crack detection. Utility Model Content

[0005] To address the existing technical problems, the main objective of this utility model is to provide a crack detection device for hydraulic structures. This device allows for convenient adjustment of the tilt angle and the angle of the detector, enabling the detector to quickly and accurately reach the appropriate angle. This allows for efficient and detailed detection of cracks at different horizontal locations in hydraulic structures, improving detection quality and efficiency.

[0006] To achieve the above-mentioned technical features, the purpose of this utility model is as follows: A crack detection device for hydraulic structures includes a detection platform body, on which a movable platform is provided.

[0025] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1: like Figures 1-6As shown, this utility model provides a crack detection device for hydraulic structures, including a detection platform body 1, on which a movable platform 2 is provided. A connecting rod 9 is rotatably mounted at the middle end of the movable platform 2 via a bearing 92, allowing the connecting rod 9 to rotate flexibly. A placement shell 3 is fixedly installed at the bottom end of the connecting rod 9, and a detector 8 is placed inside the placement shell 3. The placement shell 3 provides a safe placement space for the detector 8, protecting it from external collisions and damage, and ensuring that the detector 8 maintains a relatively stable position during horizontal rotation, thereby accurately detecting cracks in hydraulic structures. Multiple sets of connecting blocks 6 are fixedly installed on both sides of the movable platform 2. Telescopic components are provided on the multiple sets of connecting blocks 6, and pulleys 7 are provided at the ends of the telescopic components. The telescopic components can adjust their length according to the actual detection situation. In conjunction with the pulleys 7 at the ends, the device is more flexible when in contact with the surface of the hydraulic structure. A drive component is provided on the top outer surface of the movable platform 2 to control the rotation of the connecting rod 9.

[0027] Furthermore, the drive assembly includes a waterproof motor 4 fixedly mounted on the top of the movable platform 2 and a second bevel gear 91 fixedly mounted on the top of the connecting rod 9. The output shaft of the waterproof motor 4 is fixedly mounted with a first bevel gear 41, which meshes with the second bevel gear 91. This enables efficient power transmission from the waterproof motor 4 to the connecting rod 9 and changes the direction of power transmission, allowing the rotational motion of the waterproof motor 4 to be converted into the horizontal rotational motion of the connecting rod 9, thereby achieving horizontal angle adjustment of the detector 8.

[0028] Furthermore, a protective cover 5 is bolted to the top of the active platform 2, which can effectively protect the first bevel gear 41 and the second bevel gear 91 from external environmental factors such as rain, dust, debris and other erosion and collisions, which helps to extend the service life of the drive components and reduce the occurrence of equipment failures.

[0029] Furthermore, angle gauges 21 are installed on both sides of the active platform 2. The angle gauges 21 can display the horizontal tilt angle of the active platform 2 and the detector 8 in real time and accurately. The operator can precisely control the horizontal angle of the detector 8 according to the display value of the angle gauges 21 to ensure that the detector 8 is at the optimal detection angle.

[0030] Furthermore, the telescopic assembly includes a circular plate 61 fixedly installed on multiple sets of connecting blocks 6, and a damper 62 fixedly installed on the side wall of the circular plate 61. A connecting plate 64 is fixedly installed at the end of the damper 62, and a pulley 7 is rotatably installed at the end of the connecting plate 64. A spring 63 is sleeved on the outer surface of the damper 62, and the two ends of the spring 63 are fixedly connected to the circular plate 61 and the connecting plate 64 respectively. The damper 62 can absorb and dissipate the vibration energy generated by the equipment during movement or detection, reduce the impact of vibration on the detector 8, and improve the stability of detection. The spring 63 and the damper 62 work together to not only further buffer the vibration, but also provide a certain elastic restoring force when the equipment is subjected to external force, so that the pulley 7 always maintains appropriate contact pressure with the surface of the hydraulic structure.

[0031] Furthermore, the side wall of the housing 3 is provided with an observation window 33, through which the operator can clearly observe the surface area of ​​the hydraulic structure that the detector 8 is pointing at through the observation window 33 on the side wall of the housing 3. In addition, multiple sets of heat dissipation grooves 32 are provided at the bottom of the housing 3. The heat dissipation grooves 32 can promote air circulation inside the housing 3 and dissipate the heat generated by the detector 8 when it is working in a timely manner.

[0032] Furthermore, a side plate 31 is fixedly installed on one side of the housing 3 by multiple sets of bolts. When the detector 8 malfunctions or needs to be upgraded, the operator can easily open the side plate 31 to operate the detector 8, which improves the maintainability and flexibility of the equipment and reduces the maintenance time and cost of the equipment.

[0033] Furthermore, a winch is fixed to the top edge of the main body 1 of the testing platform. The end of the winch rope is connected to the movable platform 2 and its lifting height is controlled. The winch can adjust the lifting height of the movable platform 2.

[0034] Furthermore, the pulley 7 is made of rubber. The rubber roller provides excellent cushioning and anti-slip properties, preventing damage to the building surface.

[0035] Furthermore, the active platform 2, located on the side where the pulley 7 is situated, features an open structure. This open structure facilitates the observation of cracks by the detector 8.

[0036] Example 2: The working principle of a crack detection device for hydraulic structures provided by this utility model is as follows: When it is necessary to repair cracks at different horizontal positions in a hydraulic structure, the operator starts the waterproof motor 4 fixedly installed at the top of the movable platform 2. After the waterproof motor 4 starts running, its output shaft drives the first bevel gear 41 fixedly installed on it to rotate synchronously. Since the first bevel gear 41 meshes with the second bevel gear 91 fixedly installed at the top of the connecting rod 9, the rotation of the first bevel gear 41 will drive the second bevel gear 91 to rotate accordingly. Since the second bevel gear 91 is fixedly connected to the connecting rod 9, the rotation of the second bevel gear 91 will further drive the connecting rod 9 to rotate horizontally around the bearing 92. The bottom end of the connecting rod 9 is fixedly installed with a placement shell 3, so the rotation of the connecting rod 9 will drive the placement shell 3 to rotate horizontally together. Inside the housing 3 is a detector 8 for crack detection. As the housing 3 rotates horizontally, the detector 8 also changes its horizontal orientation. The operator can clearly observe the surface area of ​​the hydraulic structure that the detector 8 is pointing at through the observation window 33 on the side wall of the housing 3. Based on the actual detection needs, the operator can precisely control the operation of the waterproof motor 4 to adjust the detector 8 to a suitable horizontal angle and conduct detailed detection of cracks at different horizontal positions.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
