Problems solved by technology

[0003] The object of the present invention is to provide a kind of anti-silting method of river quays with many silts and the quays of rivers with many silts, in order to solve the above mentioned rivers with many silts such as the navigable wharves in the middle and lower reaches of the Yellow River. In the area, due to the braking of ships entering the port, the sediment is easy to deposit, and special dredging ships are used for dredging, which has adverse effects on navigation and also increases the technical problems of management costs

Embodiment 1

[0074] The embodiment of the present invention provides a silt prevention method for a river wharf with a lot of sediment, such as Figure 1-2 shown,

[0075] Include the following steps:

[0076] Step 1: A sensor 13 for sensing the ship 14 (which can be a sensor 13 for sensing the position of the ship 14, such as the sensor 13 for sensing the entry of the ship 14) and an anti-silt The nozzle 8, the anti-silt nozzle 8 is connected to the water supply system of the silt river wharf via the control valve 701, and the control valve 701 is connected to the control system 12 on the silt river wharf; The sensor 13 is installed at the start position of the top platform of the departure area 1503 at the lower part of the wharf, and several rows of anti-siltation nozzles 8 are arranged between 1.6m below the highest navigable water level and 1.6m below the lowest navigable water level, with an interval of 2m between each row. The nozzle is connected to the control valve 701, the wate...

Embodiment 2

[0086] On the basis of Example 1, as Image 6 As shown, the water supply system includes an auxiliary water supply device 3, and the auxiliary water supply device 3 includes:

[0087] The auxiliary box 31 is arranged on the dock base 1, and the auxiliary box 31 is provided with:

[0088] The first cylinder 32 is arranged at the inner upper end of the auxiliary box 31 . The first cylinder 32 is provided with a first piston 33 that slides up and down. The lower end of the first piston 33 is connected with a first piston rod 34 . The lower end of the first piston rod 34 slides through the lower end of the cylinder;

[0089] The second cylinder 35 is arranged on the right side of the first cylinder 32;

Abstract

The invention provides a silt-laden river wharf silt prevention method and a silt-laden river wharf.The method comprises the steps that 1, a ship entering sensor and a silt prevention nozzle are arranged on a wharf, the silt prevention nozzle is connected with a water supply system of the wharf through a control valve, and the control valve is connected with a control system on the wharf; 2, when the ship enters a wharf basin, water on the lower portion of the ship body is in a stirring state, an inductor transmits a signal to a control system, an anti-silt nozzle sprays pressure water flow, and silt and muddy water at the bottom of the ship are aroused to flow downstream along with river water flow; 3, when the ship is berthed in the harbor, the inductor transmits a signal to a control system, and a nozzle on the upper portion of the berthing area is controlled to stop spraying water; and 4, when the ship leaves the port, the anti-silt nozzle is opened, and if the ship arrives at the port at the same time, the nozzle on the upper portion of the berthing area is controlled not to work. Sediment at the bottom and on the lower portion of a ship is aroused through the water power generated when the ship enters the port and taken away along with river water flow, siltation of a wharf port area is prevented, and special desilting work and interference on navigation are reduced.

Description

technical field [0001] The invention relates to the technical field of silt-rich river wharfs, in particular to a silt prevention method for silt-rich river wharfs. Background technique [0002] The navigable wharfs in the middle and lower reaches of the Yellow River with a lot of sediment, due to the high sediment content of the water flow, in the wharf port area, due to the braking of ships entering the port, the sediment is easy to deposit, and special dredging vessels are used for dredging, which is unfavorable to navigation. It also increases management costs. SUMMARY OF THE INVENTION [0003] The object of the present invention is to provide a silt prevention method for a quay of a silt-rich river and a quay of a silt-sand river to solve the above-mentioned navigable wharf of a silt-rich river such as the middle and lower reaches of the Yellow River. In the area, due to the braking of ships entering the port, sediment is easy to deposit, and special dredging vessels...
