[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. 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.
[0027] Please see Figures 1-6 The present invention will describe the above technical solution in detail through the following embodiments:
[0028] A hydraulic dredging device includes a water pump for conveying dredging water, the water pump providing pressurized flushing water, and further includes:
[0029] Water supply department, such as Figures 1-3 The structure shown in this embodiment includes a water supply pipe 1 that can flow into the flushing water source and connect to the water pump outlet. Multiple evenly distributed and connected branch pipes 2 are provided on the water supply pipe 1 near the gate.
[0030] Specifically, such as Figures 4-6 The structure shown has two first flushing nozzles 3 installed on each branch pipe 2, and a second flushing nozzle 4 installed on the side of the water supply pipe 1 away from the gate. The position of each second flushing nozzle 4 corresponds to the corresponding branch pipe 2.
[0031] It should be noted that, in order to better flush away the silt deposited at the bottom of the sluice gate discharge channel, this embodiment is equipped with a first flushing nozzle 3 and a second flushing nozzle 4, as shown in the figure. Figure 5 and Figure 6 The structure shown, which is tilted downwards at 30° relative to the horizontal plane, allows the scouring water to impact the silty soil and carry it away by hydraulic force, thus avoiding the problem of silty soil deposition at the gate outlet.
[0032] In this embodiment, to improve the scouring effect of water flow on silty soil, a first scouring nozzle 3 and a second scouring nozzle 4 are provided as follows: Figure 5 and Figure 6 The concentric unequal diameter structure shown has an inlet diameter larger than the outlet diameter, which allows the water to achieve a better impact effect after passing through the structure.
[0033] To better secure the water supply unit, such as Figures 1-4 As shown in the diagram, the water pipe 1 is detachably mounted on the bracket 5 via a U-shaped retaining ring 6. In this embodiment, the bracket 5 adopts the following... Figure 3The I-shaped structure is shown, and in order to reduce the scouring resistance when discharging, the I-shaped structure of the support 5 is arranged towards the gate side, the support 5 is fixed at the base through the anchor plate 7, the anchor plate 7 is pre-buried during the construction of the river channel, and the horizontal height of the river channel is kept consistent.
[0034] The working principle of the hydraulic dredging device is as follows: the first and second dredging nozzles 3 and 4 are connected by welding in the embodiment, and in other embodiments, the first and second dredging nozzles 3 and 4 can be installed by screwing, so as to be disassembled and replaced when damaged; after the gate is closed for discharging, silt soil is deposited on the river channel foundation near the gate, the device is installed at the river channel foundation on the discharge side, water flow is delivered through the water pump, and the water flow impacts the silt soil through the first and second dredging nozzles 3 and 4, so that the silt soil is washed away with the water flow.
[0035] It should be noted that if the embodiment of the utility model has directionality indication (such as up, down, left, right, front, back, etc.), the directionality indication is only used to explain the relative position relationship, movement condition and the like between the components in a certain specific posture, and if the specific posture changes, the directionality indication also changes accordingly.
