Problems solved by technology

Drainage mechanical dredging needs to transport the water to the upstream storage first, and lead the water back after the sludge is cleaned. The cleaning cost is high, time-consuming and laborious
The dredging efficiency of the dredging ship is low, and it is impossible to effectively judge whether the mud at the bottom of the river and lake has been cleaned up. Repeated cleaning often occurs, which increases the cleaning burden

Embodiment 1

[0035] see Figure 1-5 As shown, the present invention is a river and lake dredging device, comprising a support base 1, a fixed foot 2, a winch 3, a driver 4, a telescopic rod 5, a drainage pipe 6, a photoelectric sensor 7 and an MCU control chip 8; the support base 1- A number of fixed feet 2 are fixed on the surface; the other surface of the support seat 1 is fixed with an MCU control chip 8, which is used to control the dredging device to work underwater; one end of the fixed feet 2 is connected to the winch 3 through the connecting shaft 301, and the winch 3 stirs up the mud , easy to remove; one surface of the fixed foot 2 is connected with the driver 4, and the driver 4 controls the dredging device to move underwater; one end of the driver 4 is connected with the telescopic rod 5, and the telescopic rod 5 controls the height of the dredging device and the underwater bottom surface; the fixed leg 2. A photoelectric sensor 7 is fixed on the surface. The photoelectric sens...

Embodiment 2

[0042] see Figure 7 Shown, a kind of control method of river and lake desilting device comprises the following steps:

[0043] SS01: When the dredging equipment is just launched into the water, the photoelectric sensor 7 monitors the signal strength in the river water, transmits the data to the MCU control chip 8, and records it as the initial strength;

[0044] SS02: MCU control chip 8 controls the extension of telescopic rod 5;

[0045] SS03: MCU control chip 8 starts winch 3 to stir up the mud;

[0046] SS04: The photoelectric sensor 7 monitors the signal strength in the river water, and transmits the data to the MCU control chip 8;

[0047] SS05: The MCU control chip 8 judges whether the surrounding mud is cleared. When the signal strength of the photoelectric sensor 7 changes from zero to half of the initial signal strength, it is judged that the mud in this direction is basically cleared;

[0048] SS06: MCU control chip 8 controls telescopic rod 5 to shrink;

[0049...

Embodiment 3

[0051] The principle of monitoring whether the silt of a river and lake dredging device is clean is as follows: when the dredging device enters the water, the optical signal intensity that can be achieved through the river water is first monitored by the photoelectric sensor 7, which is recorded as the initial intensity, and then the silt is dredged When the device is working, because the silt is stirred up, the intensity of the light signal received by the photoelectric sensor 7 becomes lower. As the silt is gradually removed, the light transmittance of the water increases. When the light signal intensity can reach half of the initial intensity, it indicates that The silt has been basically removed, and the cleared area can still be continuously desilted due to the fluidity of the water after the dredging device is moved.

Abstract

The invention discloses a desilting device for rivers and lakes and a control method of the desilting device, and relates to the technical field of desilting. The desilting device comprises a supporting base, fixed feet, winches, drivers, telescopic rods, photoelectric sensors and an MCU control chip. The multiple fixed feet are fixed to one surface of the supporting base. The MCU control chip isfixed to the other surface of the supporting base. One end of each fixed foot is connected with the corresponding winch through a connection shaft. One surface of each fixed foot is connected with thecorresponding driver. One end of each driver is connected with the corresponding telescopic rod. The fixed feet, the winches, the photoelectric sensors, the drivers and the telescopic rods are all electrically connected with the MCU control chip. According to the desilting device, by improving the fixed feet of the desilting device, the desilting device can move under water; and by installing thephotoelectric sensors on the fixed feet to monitor the silt removal degree, the desilting device can automatically recognize positions where silt is not removed, and the desilting device is controlled to move towards the positions where the silt is not removed.

Description

technical field [0001] The invention belongs to the technical field of dredging, and in particular relates to a river and lake dredging device and a control method thereof. Background technique [0002] In order to protect the ecological balance of rivers and lakes and improve the utilization rate of water resources, dredging of rivers and lakes is required at regular intervals. Common dredging methods include drainage mechanical dredging or use of dredging boats. Drainage mechanical dredging needs to transport water to the upstream storage first, and then lead the water back after the sludge is cleaned. The cleaning cost is high, time-consuming and labor-intensive. The dredging efficiency of the dredging ship is low, and it is impossible to effectively judge whether the silt at the bottom of the river and lake has been cleaned up. Repeated cleaning often occurs, which increases the cleaning burden. Contents of the invention [0003] The purpose of the present invention ...
