Technical Field

[0001] The utility model relates to the technical field of underwater silt cleaning, and particularly relates to a mud inlet assembly. Background Art

[0002] The underwater dredging project has always been on a large scale and requires a great deal of manpower and material resources. After the river is blocked and drained, the silt on the river bank is removed. The construction of the main river channel project is difficult, and the blockage of the main river further affects the normal drainage of the water system.

[0003] In order to further improve the efficiency of river dredging and reduce the dredging cost, people have successively developed equipment such as jet stirring and underwater excavation to dredge the river. However, these mechanical dredging processes are time-consuming and laborious, and most of the existing river silt cleaning devices dig the silt from the river bottom. However, the silt in the river itself has a large water content, resulting in an overweight silt, which affects the working efficiency of removing the river bottom silt. In addition, in some waters, there may be blocky and hard soil at the river bottom, and traditional methods such as jet stirring are not easy to clean.

[0004] Therefore, how to achieve efficient river silt cleaning is a problem that needs to be considered by those skilled in the art. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a mud inlet assembly to solve the problems of low efficiency of underwater silt cleaning and difficulty in cleaning blocky soil in the prior art.

[0006] The technical solution of the utility model is: a mud inlet assembly, including a plurality of mud inlets arranged in parallel.

A first shovel plate is connected to the lower end of the trumpet-shaped opening, and a mud outlet is connected to the second opening end. The mud outlet is connected to a mud suction pump. Driven by a dredger, the first opening end of the mud inlet assembly moves forward, so that the silt enters from the first opening end and is discharged from the mud outlet.

[0007] Preferably, a filter screen is arranged inside the trumpet-shaped opening, and the filter screen covers the mud outlet.

[0008] Preferably, a window is arranged on the upper baffle, and the window is arranged at one end of the filter screen away from the mud outlet.

Specific embodiments

[0026] The following combines specific embodiments to further elaborate on the content of the present utility model:

[0027] As Figures 1-3 shown, the present utility model is applied to the cleaning of underwater silt. The mud inlet assembly is connected to the robotic arm or other connecting devices of the cleaning ship through the mounting plate and is placed at the bottom of the water. As the cleaning ship moves forward, the first opening end of the mud inlet assembly moves forward. The first shovel plate and the second shovel plate scoop up the underwater silt, and the silt enters the second opening end along the flared opening and is discharged through the mud outlet. Among them, the underwater garbage or larger particles are filtered by the filter screen; water is discharged through the second pipeline and the third pipeline to wash the silt to facilitate the discharge of the silt in the mud outlet. Specifically:

[0028] A mud inlet assembly includes a plurality of mud inlets 1 arranged in parallel. The mud inlet 1 includes a left baffle 11, a right baffle 12, and an upper baffle 13. The left baffle 11, the right baffle 12, and the upper baffle 13 together form a flared opening 1a. The larger opening end of the flared opening 1a is the first opening end 1b, and the smaller opening end is the second opening end 1c. The lower end of the flared opening 1a is connected with a first shovel plate 14 and a second shovel plate 15. The first shovel plate 14 is inclined, and the side close to the first opening end 1b is lower than the side close to the second opening end 1c. The side of the first shovel plate 14 close to the first opening end 1b is provided with a toothed edge; the second shovel plate 15 is closer to the second opening end 1c relative to the first shovel plate 14; the second shovel plate 15 is inclined, and the side close to the first shovel plate 14 is provided with a toothed edge. The second opening end 1c is connected with a mud outlet 16, and the mud outlet 16 is connected with a suction pump (not shown in the figure).

[0029] In this embodiment, driven by the dredger, the inlet 1 assembly moves forward with the first opening end 1b facing forward. The first shovel plate 14 and the second shovel plate 15 shovel the silt and, under the guidance of the left baffle 11 and the right baffle 12, flow towards the second opening end 1c. Finally, under the suction of the suction pump connected to the outlet 16, the silt is sucked out.

[0030] A filter screen 17 is arranged inside the flared opening 1a, and the filter screen 17 covers the outlet 16. A window 18 is arranged on the upper baffle 13, and the window 18 is arranged at one end of the filter screen away from the outlet 16. When there is garbage or large - particle stones in the sucked silt, it can be filtered by the filter screen 17 to avoid blockage of the outlet 16. As the silt enters, the garbage can be discharged from the window 18 along with the flow of the silt; at the same time, the silt that cannot be sucked in time by the outlet 16 can also be discharged through the window 18, avoiding the situation where the silt inside the flared opening 1a cannot be discharged in time and accumulates and blocks.

[0031] At the upper end of the first opening end 1b, a first pipe 19 is arranged. The upper end of the first pipe 19 is connected to a water pump (not shown in the figure), and the lower end is connected to a plurality of second pipes 191. The ends of the second pipes 191 away from the first pipe 19 are connected to a first elbow 192, and the outlet end of the first elbow 192 corresponds to the first shovel plate 14.

[0032] A plurality of third pipes 193 are connected to the first pipe 19. The lower ends of the third pipes 193 pass through the upper baffle 13 and are connected to a second elbow 194, and the outlet end of the second elbow 194 corresponds to the second shovel plate 15.

[0033] In this embodiment, the water passing through the first pipe 19 is discharged through the second pipes 191 and the third pipes 193 to wash the silt inside the flared opening 1a, so as to increase the fluidity of the silt and further increase the discharge efficiency of the outlet 16.

[0034] There are three inlets 1. The adjacent two first opening ends 1b are connected by the edges of the left baffle 11 and the right baffle 12; the adjacent two second opening ends 1c are connected by a connecting plate 20, and an installation plate 21 is connected to the connecting plate 20. A lifting ring 22 is arranged at the upper end of the inlet 1. A front baffle 23 is arranged at the upper end of the first opening end 1b. The front baffle 23 is arranged in front of the first pipe 19, and the lower end of the front baffle 23 is connected to the front edge of the upper baffle 13. In this embodiment, the arrangement of multiple inlets 1 can increase the cleaning efficiency of the silt; the arrangement of the front baffle 23 can prevent the silt from crossing the inlet 1 when there is too much silt, which may affect the window 18, the first pipe 19, and the connection between the inlet 1 assembly and the dredger.
