Description

TECHNICAL FIELD

[0001] The application belongs to the field of underwater operation equipment, and particularly relates to an underwater dam maintenance device. BACKGROUND

[0002] At present, underwater dams, as important water conservancy engineering facilities, play a crucial role in flood control, power generation, irrigation and the like. However, due to long-term influences of factors such as water flow scouring, geological changes and self material aging, the surface of the underwater dam often has defects such as cracks. If these cracks are not timely maintained, the dam structure may be damaged, thereby affecting the overall stability and safety of the dam.

[0003] When the traditional underwater dam maintenance equipment is used to maintain the surface cracks, the position of the equipment needs to be constantly moved to cover the entire maintenance area. This maintenance method is not only inefficient, but also increases the operation difficulty and cost. At the same time, due to the complex and changeable underwater environment, the frequent movement of the equipment may cause additional damage to the dam structure.

[0004] In view of the above problems, the industry has been seeking more efficient and stable underwater dam maintenance equipment. However, most of the existing equipment has problems such as complex operation and insufficient stability, which is difficult to meet the needs of actual maintenance work. Therefore, it is particularly important to develop an underwater dam maintenance device which is simple to operate, stable, improves maintenance efficiency and quality. CONTENT OF THE INVENTION

This design makes the cooperation of the mud troweling mechanism 5 and the rock cutting mechanism 6 more stable, easy to operate, and significantly improves the efficiency and quality of maintenance.

[0044] Further, Figures 4-7 Different angle diagrams showing the connection of the mud troweling mechanism 5 and the first walking beam 12 in the present application are shown in Figures 4-7 As shown, the mud troweling mechanism 5 comprises a mounting frame 51 and a troweling plate 52, the mounting frame 51 is connected to the side of the first walking beam 12 and the other side is connected to the troweling plate 52, and the troweling plate 52 is arranged in parallel with the first walking beam 12. The troweling plate 52 is firmly connected to the first walking beam 12 through the mounting frame 51 and moves along the extension direction of the dam working surface by means of the first walking beam 12, so that the troweling plate 52 can effectively cover and realize the filling and troweling of cracks in a certain working area during one working process, which significantly improves the efficiency and quality of crack repair.

[0045] In some preferred embodiments of the present application, as shown in Figure 4 , Figure 6 and Figure 7 The mud troweling mechanism 5 further comprises a rotating connection part 53, and the two ends of the rotating connection part 53 are respectively connected to the mounting frame 51 and the troweling plate 52.

[0046] In some preferred embodiments of the present application, as shown in Figure 5 , Figure 6 and Figure 7As shown, the mud leveling mechanism 5 further comprises a first moving platform 54 and a carrying shovel 55 connected to the first moving platform 54, the carrying shovel 55 can reciprocate in a direction perpendicular to the dam working surface, the first moving platform 54 is slidingly connected to the side of the first walking beam 12 and is arranged opposite to the mud board 52, and the first moving platform 54 can reciprocate along the extension direction of the first walking beam 12.

[0047] Further, Figure 8 As shown in the perspective view of the rock cutting mechanism 6 in the application connected with the second walking beam 13, Figure 8 As shown, the rock cutting mechanism 6 comprises a second moving platform 61, a mechanical arm 62 and a cutting head 63, the second moving platform 61 is slidingly connected with the second walking beam 13 and can reciprocate along the extension direction of the second walking beam 13, one end of the mechanical arm 62 is connected with the second moving platform 61 and the other end is connected with the cutting head 63. Through the precise cooperation of the second moving platform 61 and the second walking beam 13, the mechanical arm 62 and the cutting head 63 carried thereby are endowed with the ability to perform efficient tasks in a wider area. The mechanical arm 62 can not only drive the cutting head 63 to accurately perform the breaking work on the dam surface through flexible reciprocating movement, but also has the function of self-adjusting the working direction and working angle, which greatly expands the working range of the cutting head 63 and further improves the efficiency and flexibility of the overall operation.

[0048] In some preferred embodiments of the application, as Figure 8 As shown, the number of mechanical arms 62 is multiple, and the multiple mechanical arms 62 are correspondingly arranged with multiple cutting heads 63, each mechanical arm 62 can carry different types of cutting heads 63 for work. This design enables different types of cutting heads 63 to be directly applied for work without replacing the cutting heads 63 during one operation, thereby greatly improving the work efficiency and flexibility.

[0049] In some preferred embodiments of the application, the number of second moving platforms 61 can also be multiple, and each second moving platform 61 can carry multiple mechanical arms 62.

The main function of the waste collection box 9 is to collect the waste generated by the carrying shovel 55 and the cutting head 63 during the operation. This design effectively prevents the accumulation of waste, thereby avoiding unnecessary interference of the waste to the crack maintenance work, and ensuring the efficient and smooth operation of the maintenance work.

[0052] In some preferred embodiments of the present application, the waste collection box 9 is connected to the first walking beam 12 and / or the second walking beam 13, so that the waste collection box 9 can move with the first walking beam 12 and / or the second walking beam 13, and can timely and efficiently collect the waste.

[0053] Further, as shown in Figure 3 The mud processing mechanism comprises a mud tank 81, a mud receiving pipe 82, a mud discharging pipe 83 and a mud outlet nozzle 84 connected in sequence with the mud tank 81.

The water changing cover 14 is provided with a water inlet and a water outlet. A suction mechanism is installed in the water changing cover 14.

Such design enables the water changing cover 14 to wrap the dam surface more tightly and closely, thereby enhancing the sealing performance of the device and effectively improving the efficiency and quality of water changing, further ensuring the stability and efficiency of the entire maintenance operation.

[0057] The working process of the maintenance device in this application is as follows:

[0058] After receiving the task, the working mother ship will start and sail to the designated target dam location. Once arrived, it will use the traction mechanism 2 to steadily pull and lower the maintenance device to the designated area of the target dam. Next, the detection mechanism will start to conduct detailed detection on the maintenance location to accurately determine the specific location that needs to be maintained.

[0059] After detection confirmation, the traveling mechanism 3 and the adsorption mechanism 4 will work together to ensure that the maintenance device can be accurately positioned at the location that needs to be handled. At this time, the carrying shovel 55 will play its role, flexibly picking up soil or bricks, and performing paving or collecting work as needed, to prepare for the subsequent steps.

[0060] Subsequently, the rock cutting mechanism 6 will work closely with the second walking beam 13 to conduct forced breaking operations on the dam surface to remove damaged or uneven parts to ensure the flatness and stability of the dam surface.

[0061] Finally, the mud troweling mechanism 5 cooperates with the mud treatment mechanism to jointly conduct mud filling and troweling work on the dam. The mud troweling mechanism 5 will use the mud provided by the mud treatment mechanism to accurately fill the damaged parts of the dam surface, and through its troweling function, the dam surface will be restored to flatness, thereby achieving the purpose of repair.
