Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, specifically to an underwater dam crack repair structure. Background Technology
[0002] Submersible dams are hydraulic structures built in aquatic environments such as rivers, lakes, or seas. Their main functions include intercepting water flow, regulating water levels, storing water and energy, and controlling siltation. The bottom of the dam is deeply embedded below the riverbed or seabed to ensure the overall structural strength and safety. The top may house spillways, gate systems, and monitoring facilities for precise management of water release and response to extreme flooding. As a key component of water conservancy projects, underwater dams not only support various economic benefits such as power generation, irrigation, and navigation, but also have a profound impact on the surrounding ecological environment, such as altering aquatic ecosystems and affecting fish migration routes. Therefore, comprehensive environmental assessments and ecological compensation measures are necessary during planning and construction. Through precise engineering design and construction techniques, underwater dams can operate stably for extended periods under complex and variable hydrological conditions, providing vital water resource regulation services to human society.
[0003] Underwater dams develop cracks due to a combination of factors, including uneven geological settlement, thermal expansion and contraction caused by temperature changes, construction quality defects, water pressure, and material aging. A search revealed Chinese Patent Publication No. CN222541391U, which discloses a dam panel crack control structure based on induced joint construction. This structure can control the generation and development of cracks inside the plain concrete panel and improve the water-proof performance of the plain concrete panel. It eliminates the need for repairs and reduces construction costs. However, in actual use, it has been found that this solution relies entirely on a pre-set induced area and induced plates to guide the cracks in a specific direction. If changes in the external environment exceed the design expectations, the induced cracks may fail, and the cracks may deviate from the predetermined path and not be detected in time.

[0006] (II) Technical Solution
[0007] To achieve the above objectives, the present invention provides the following technical solution: an underwater dam crack repair structure, including a main board, the main board including a main fixing plate with a first mounting hole at the tail, the main board also including a side fixing plate disposed on the side of the main fixing plate, the surface of the side fixing plate being provided with a sliding groove;
[0008] A movable plate is slidably mounted inside the slide groove via a slider. A connecting plate is provided on the upper surface of the main plate. The connecting plate includes a main connecting end and a side connecting end located outside the main connecting end. A connecting rod is rotatably mounted on the upper surface of the side connecting end via a connector. The other end of the connecting rod is rotatably connected to the upper surface of the movable plate via a connector.
[0009] As a preferred embodiment of this utility model, a through rod is welded to the bottom of the connecting plate, and a through plate is welded to one side of the upper surface of the main board, allowing the through rod to slide through. A limit block is provided at the end of the through rod.
[0010] As a preferred technical solution of this utility model, a baffle is provided on the outside of the through rod to block the through rod, the through plate and the limiting block.
[0011] As a preferred embodiment of this utility model, one end of the baffle is provided with an opening, and the connecting plate can slide inside the baffle through the opening.
[0012] As a preferred technical solution of this utility model, the side fixing plates are provided in two sets, and the two sets of side fixing plates are arranged opposite to each other on both sides of the main fixing plate. The slide grooves are provided in two sets, and each set of slide grooves has a set of movable plates slidably installed inside by a set of sliders. The two sets of movable plates are rotatably connected to the two sets of side fixing plates by two sets of connecting rods.
[0013] As a preferred embodiment of this utility model, the first mounting hole is provided in two sets.
[0014] As a preferred embodiment of this utility model, each set of side fixing plates is provided with two sets of second mounting holes at its end, and the connecting plate is provided with a set of third mounting holes at its end.
[0015] As a preferred embodiment of this utility model, the slider is installed on the bottom side of the movable plate, and a sensor is installed on the outside.
[0016] As a preferred embodiment of this invention, the length of the movable plate is longer than the length of the slide groove, and the bottom of the movable plate can cover the top of the slide groove.
[0017] Compared with the prior art, this utility model provides an underwater dam crack repair structure, which has the following beneficial effects:
[0018] 1. This utility model uses a main board, a connecting plate, a first mounting hole, a second mounting hole, and a third mounting hole to perform preliminary repairs on cracks in the dam body. The two sets of first mounting holes and four sets of second mounting holes increase the stability of the main board. The through plate, through which the through rod can slide, facilitates the length adjustment of the connecting plate according to the length of the crack, making the device applicable to the repair of cracks of different widths.
[0019] 2. In this utility model, after the initial repair of cracks on the main board and connecting plate, the cracks tend to enlarge and shift with increasing usage time. This causes the connecting plate to move, and the connecting rod mounted on the upper surface of the connecting end on the main board rotates, causing an angular shift. This results in the other end of the connecting rod pressing against the movable plate. The movable plate slides inside the slide groove via a slider. When the movable plate slides to a certain position, it causes a mechanical touch micro switch mounted on the outside of the slider to contact the inner wall of the slide groove, thereby sending a signal to the signal receiver for alarm reminder.
[0020] 3. This utility model avoids the problem of water pollutants entering the structure and causing blockage by using baffles and setting the length of the movable plate to be longer than the length of the chute. Multiple devices can be arranged in a relative sequence during use to repair cracks of different lengths. At the same time, the relative sequence of multiple devices can further increase the repair strength and improve the repair effect. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0030] Please see Figures 1-4 A structure for repairing cracks in an underwater dam includes a main board 1. The main board 1 includes a main fixing plate 101 with two first mounting holes 100 at its tail. The main board 1 also includes a side fixing plate 102 disposed on the side of the main fixing plate 101. The surface of the side fixing plate 102 is provided with a sliding groove 103, and two second mounting holes 200 are opened on one side.
[0031] A movable plate 2 is slidably mounted inside the slide groove 103 via a slider 10. A connecting plate 3 is provided on the upper surface of the main plate 1. The connecting plate 3 includes a main connecting end 31 and a side connecting end 32 located outside the main connecting end 31. A connecting rod 4 is rotatably mounted on the upper surface of the side connecting end 32 via a connector. The other end of the connecting rod 4 is rotatably connected to the upper surface of the movable plate 2 via a connector. A through rod 33 is also welded to the bottom of the connecting plate 3. A through plate 34 is welded to one side of the upper surface of the main plate 1, allowing the through rod 33 to slide through. A limit block 35 is provided at the end of the through rod 33. A baffle 5 is provided on the outside of the through rod 33 to block the through rod 33, the through plate 34, and the limit block 35. An opening 50 is provided at one end of the baffle 5, through which the connecting plate 3 can slide inside the baffle 5. A set of third mounting holes 300 is provided at the end of the connecting plate 3.
[0032] Furthermore, the slider 10 is installed on the bottom side of the movable plate 2, and a sensor is installed on the outside. The sensor is a KW10-01ARJ mechanical touch micro switch, and the sensor output is connected to an HC-05 Bluetooth module as a signal receiver via a network.
[0033] Furthermore, the length of the movable plate 2 is longer than the length of the slide 103, and the bottom of the movable plate 2 can cover the top of the slide 103.
[0034] First, place the main board 1 on one side of the crack in the dam body. Then, pass the fixing pile through the first mounting hole 100 and the second mounting hole 200 in sequence to fix the main board 1. Then, fix the connecting plate 3 to the other side of the crack in the dam body through the third mounting hole 300. The main board 1 and the connecting plate 3 are used to perform preliminary repairs on the crack in the dam body through the first mounting hole 100, the second mounting hole 200 and the third mounting hole 300.
[0035] When the main board 1 is fixed to one side of the crack in the dam body, the two sets of first mounting holes 100 and the four sets of second mounting holes 200 increase the stability of the main board 1. The through plate 34 through which the through rod 33 can slide is used to make it easy to adjust the length of the connecting plate 3 according to the length of the crack, so that the device can be used to repair cracks of different widths. At the same time, the end of the through rod 33 is limited by the limiting block 35 to prevent the through rod 33 from falling off the through block.
[0036] After the motherboard 1 and connecting plate 3 perform initial repairs on the cracks, the cracks are prone to enlarge and displacement as usage time increases. This causes the connecting plate 3 to move, and the connecting rod 4, which is mounted on the upper surface of the connecting end 32 on the motherboard 1 via the rotating connector, shifts at an angle, causing the other end of the connecting rod 4 to press against the movable plate 2. The movable plate 2 slides inside the slide groove 103 via the slider 10. Since the core of the mechanical touch micro switch is to achieve rapid circuit switching by triggering the deformation of the spring through mechanical force, when the movable plate 2 slides to a certain position, it causes the mechanical touch micro switch mounted on the outside of the slider 10 to come into contact with the inner wall of the slide groove 103. This causes the external force to act on the transmission element of the mechanical touch micro switch, thereby sending a signal to the HC-05 Bluetooth module. After receiving the signal, the HC-05 Bluetooth module issues a warning for alarm reminder.
[0037] Since this device is used on an underwater dam, where there are various unidentified organisms and disturbances, a baffle 5 is installed on the outside of the through rod 33 to shield the through rod 33, through plate 34, and limiting block 35. Similarly, the length of the movable plate 2 is set to be longer than the length of the chute 103, so that the bottom of the movable plate 2 can shield the top of the chute 103, thereby preventing pollutants in the water from entering the structure and causing blockage.
[0038] Because the baffle 5 restricts the movement space of the connecting plate 3, an opening 50 is provided at one end of the baffle 5 to provide movement space for the connecting plate 3.
[0039] Please see Figure 5 This device forms a main repair structure through the main board 1, movable plate 2, connecting plate 3, connecting rod 4, and baffle 5. In use, multiple devices can be arranged in a relative sequence to repair cracks of different lengths. At the same time, the relative sequence of multiple devices can further increase the repair strength and improve the repair effect.
[0040] In use, the main board 1 is first placed on one side of the crack in the dam body. The fixing pile is then passed through the first mounting hole 100 and the second mounting hole 200 in sequence to fix the main board 1. The connecting plate 3 is then fixed to the other side of the crack through the third mounting hole 300, achieving the initial repair effect of the main board 1 and connecting plate 3 on the crack. Simultaneously, the through plate 34, through which the through rod 33 can slide, allows for length adjustment of the connecting plate 3 according to the crack's length, enabling the device to repair cracks of different widths. After the main board 1 and connecting plate 3 perform the initial repair, the crack is prone to enlargement over time. Displacement causes the connecting plate 3 to move, and the connecting rod 4, which is rotated and mounted on the upper surface of the connecting end 32 on the main board 1, shifts at an angle, causing the other end of the connecting rod 4 to press against the movable plate 2. The movable plate 2 slides inside the slide groove 103 via the slider 10. When the movable plate 2 slides to a certain position, it causes the mechanical touch micro switch mounted on the outside of the slider 10 to contact the inner wall of the slide groove 103, thereby sending a signal to the signal receiver for alarm reminder. At the same time, the baffle 5 and the setting of the length of the movable plate 2 to be longer than the length of the slide groove 103 prevent pollutants in the water from entering the structure and causing blockage.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
