[0028] In order to more clearly demonstrate the technical content of the present invention, it is further described below in conjunction with specific embodiments.

[0029] like Figure 1-3 As shown, the utility model mainly provides an underwater repair material adding device, including a traction trolley 1 and a rotary drum slotting mechanism 7 connected to the traction trolley 1. The traction trolley 1 can drive the rotary drum slotting mechanism 7 to rotate while moving on the bottom of the water to complete the adding of the repair material.

[0030] In this embodiment, the tractor 1 includes a frame 11, two rollers 12 are rotatably connected to the two sides of the frame 11, and a motor 13 for driving the rollers 12 is also installed on the frame 11. Considering that the tractor 1 needs to be able to move underwater, and the underwater mud is usually soft mud or silt with poor bearing capacity, in order to enable the tractor 1 to continue to travel on the surface of the underwater mud, a wider roller 12 is selected.

[0031] At the same time, a plurality of evenly arranged protrusions 14 are also provided on the wheel surface of the roller 12 to increase the friction between the roller and the bottom mud, so as to ensure that the roller can roll on the soft surface of the underwater bottom mud without sinking into the bottom mud.

[0032] A horizontal support 2 extending backward is installed at the rear of the frame 11, and a rotary drum slotting mechanism 7 is installed on the horizontal support 2. The rotary drum slotting mechanism 7 includes a storage bin 71 and a rotary drum 72 with closed ends; both ends of the storage bin 71 are provided with end covers 73, and a rotating shaft 74 is fixedly connected to the middle position of the end cover 73, and the rotating shaft 74 is rotatably connected to the horizontal support 2. When the traction trolley 1 moves, the rotating shaft 74 on the horizontal support 2 will rotate along with the movement of the traction trolley.

[0033] In this embodiment, a through hole 77 is provided at the center of the rotating drum 72, and the storage silo 71 is located in the through hole 77 of the rotating drum, wherein the rotating drum 72 is sleeved on the outer peripheral wall of the storage silo 71 and is rotationally connected with the storage silo 71; when the traction trolley moves, the rotating drum 72 sleeved on the storage silo 71 will rotate with the traction trolley, and the storage silo 71 is always in a fixed state during the rotation process. Specifically, the rotation relationship between the rotating drum and the storage silo can be realized by setting a ball bearing, and in order to avoid affecting the normal falling of the repair material in the storage silo, the ball bearings are set at both ends of the storage silo, and the ball bearings are common existing technologies, so they will not be described in detail here.

[0034] And because the storage silo 71 is an internally hollow component, the storage silo can be used to store repair materials; wherein, a small conveying hole 75 for conveying repair materials is vertically arranged at the bottom center of the storage silo, and the small conveying hole is interconnected with the storage silo.

[0035] The rotary drum slotting mechanism 7 also includes a plurality of feeding pipes 6, which are installed at equal angles on the side of the rotary drum 72; a through hole 65 is provided in the feeding pipe 6 (the through hole passes through the feeding pipe and the rotary drum on the feeding pipe in sequence), and the through hole 65 is used to connect with the conveying hole 75 in the rotary drum 72. In order to facilitate the excavation of the bottom mud, one end of the feeding pipe 6 is provided with a chamfered surface 66 facing the rotation direction of the rotary drum 72. When the feeding pipe 6 rotates with the rotating drum 72, the feeding pipe 6 at the bottom of the rotating drum 72 will be inserted into the bottom mud. When the feeding pipe 66 reaches a vertical state, the through hole 65 in the feeding pipe and the conveying hole 75 in the storage silo 3 can coincide with each other. Under the action of gravity, the repair material in the storage silo 71 will fall into the through hole 65 in the feeding pipe along the conveying hole 75, and then enter the silt soil. With the rotation of the rotary drum slotting mechanism 7, the through hole 65 in the next feeding pipe 6 will coincide with the conveying hole 75 in the storage silo again. The overlapping in the vertical state causes the repair material in the storage silo to be dropped into the silt soil in another opening, thereby completing the automatic delivery of the repair material; that is, the rotary drum grooving mechanism 7 rotates one circle, cuts the soil six times, and the repair material is dropped six times; at the same time, under the influence of the water flow rate, the cut soil will be slowly covered by the silt on the surface, thereby completing the filling; and the aperture of the conveying hole 75 in this example is set to be slightly larger than the aperture of the through hole 65 in the feeding pipe, so that the repair material in the rotary drum 72 can be dropped directly from the conveying hole into the feeding pipe 6 for delivery.

[0036] The repair material delivery mechanism disclosed in the utility model also includes a feeding mechanism 5. The feeding mechanism 5 includes a feeding hopper 51 and a feeding pipe 52. One end of the feeding pipe 52 is fixedly connected to the bottom of the feeding hopper 51, and the other end is connected to the rotating shaft 74 of the storage silo. The rotating shaft 74 is also a tubular structure. The bottom end of the feeding pipe 52 extends from the free end of the rotating shaft into the interior of the rotating shaft and communicates with the storage silo 71. The outer wall of the feeding pipe 52 is rotatably connected to the peripheral edge portion 76 of the through hole at the end of the rotating shaft and is well sealed. Therefore, the rotation of the rotating shaft does not drive the feeding pipe 52 to rotate. When the repair material stored in the storage silo 71 is about to be used up, the repair material can be transported to the interior of the storage silo 71 through the feeding hopper 51 and the feeding pipe 52, thereby completing the replenishment of the repair material inside the storage silo 71.

[0037] In this embodiment, in order to facilitate better control of the tractor, a wireless communication control device 8 is provided on the tractor, which is electrically connected to a power source (not shown in the figure for simplicity). The wireless communication control device 8 may include an antenna, which is electrically connected to the tractor motor, and can establish a connection with a remote terminal through the antenna (wireless communication module) and perform remote signal communication transmission; the user can control the travel and steering of the tractor through the remote terminal, which greatly reduces equipment and labor costs.

[0038] In summary, the utility model is used to solve the problem of in-situ repair material delivery at the bottom of rivers and lakes due to the complex and changeable underwater landforms. Its main configuration includes a traction trolley 1, a feeding mechanism 5, and a rotary drum slotting mechanism 7. The feeding hopper 51 in the feeding mechanism 5 can be made of a sealing material with a density lower than that of water and good waterproofness. It floats on the water surface during operation and is connected to the underwater rotary drum slotting mechanism 7 through a feeding pipe 52. The repair material in the feeding hopper 51 enters the storage silo 71 through the feeding pipe 52, and is delivered through the conveying holes 75 in the storage silo 71 to the through holes 65 on the feeding pipe on the rotary drum. The power source in this mechanism (not shown in the figure for simplicity) can be a lithium battery with a high power density, which can then drive the motor to drive the roller for traction work, and can also be used as a power source; except for the feeding hopper 51, the materials of other components are mainly stainless steel with strong corrosion resistance, which can work under extreme conditions and have a high application and promotion value in actual engineering.

[0039] It should be noted that: the utility model installs a rotary drum grooving mechanism on the horizontal bracket of the traction trolley, and uses a feeding pipe to throw the repair material into the mud at the bottom of the water. As the traction trolley moves, the rotary drum on the feeding pipe also rotates. During the rotation, grooves can be formed on the bottom mud through the oblique cut surface on the feeding pipe. At the same time, the repair material in the storage silo is fed into the formed groove through the feeding pipe, thereby realizing the automatic feeding of the bottom mud repair material underwater. Therefore, the use of the underwater repair material feeding device disclosed by the utility model can effectively improve the feeding efficiency of the repair material.

[0040] At the same time, a moisture-proof and anti-collision layer is arranged inside the hopper to prevent the material from getting wet or being squeezed and deformed; wherein the top opening position of the hopper is always higher than the water surface. In an optional embodiment, the hopper can be installed on a working ship on the water surface.

[0041] In another optional embodiment, the hopper is installed on a float or valve plate floating on the water (a striking color paint may be used for easy positioning). When the repair material needs to be replenished, the operator drives the boat close to the hopper and transports the material through the hopper.

[0042] The above-mentioned related explanations and descriptions of the embodiments are for the convenience of ordinary technicians in the technical field to understand and apply the utility model. It is obvious that those familiar with the technology in the field can easily make various modifications to these contents and apply the general principles described here to other embodiments without creative work. Therefore, the utility model is not limited to the above-mentioned related explanations and descriptions of the embodiments. Improvements and modifications made by technicians in the field based on the disclosure of the utility model without departing from the scope of the utility model should be within the scope of protection of the utility model.
