Description
Technical Field
[0001] This invention belongs to the field of river dredging, specifically involving in-situ cleaning of river silt and slope reinforcement devices and methods. Background Technology
[0002] Rivers, as carriers of water resources, are primarily affected by sedimentation, which is a major cause of current river siltation. The accumulation of silt is a key factor affecting river safety, thus necessitating river dredging. Furthermore, due to water erosion, riverbank reinforcement is required to ensure the normal use of the river. Current methods typically involve manually removing the silt first, followed by manual slope reinforcement, which is not only labor-intensive and time-consuming but also incurs high costs for silt transportation and disposal, resulting in high overall construction costs. Summary of the Invention
[0003] The main objective of this invention is to provide a device and method for in-situ cleaning of river silt and slope reinforcement, which can simultaneously clean river silt and reinforce river slopes, saving time and effort.
[0004] The technical solution adopted in this invention is:
[0005] A device for in-situ cleaning of river silt and slope reinforcement includes a silt cleaning unit, an intelligent control unit for slurry moisture content, a slope spraying reinforcement unit, and a power unit.
[0006] The silt removal unit is used to remove silt from the river channel;
[0007] The intelligent control unit for mud moisture content controls the moisture content of the sludge delivered by the sludge cleaning unit; when the sludge moisture content is lower than the set value, water is introduced into the sludge through the inlet; when the sludge moisture content is higher than the set value, the drainage mechanism is automatically controlled to drain water.
[0008] The slope spraying reinforcement unit mixes the silt delivered by the intelligent control unit for slurry moisture content with the solidifying agent, and sprays it onto the riverbank slope through a rotating nozzle for reinforcement.
[0009] The power unit provides kinetic energy to the sludge cleaning unit, electrical energy to the sludge cleaning unit, the intelligent control unit for mud moisture content, and the slope spraying and reinforcement unit, and controls the operation of the sludge cleaning unit, the intelligent control unit for mud moisture content, and the slope spraying and reinforcement unit.
[0010] A further embodiment is that the sludge cleaning unit includes a sludge cleaning box, a rolling collection shaft, and a filter screen;
[0011] The sludge cleaning box is connected to the intelligent control unit for sludge moisture content via a connecting hose, and the bottom of the sludge cleaning box is open.
[0012] The rolling collection shaft is placed inside the sludge cleaning box to achieve in-situ cleaning and transportation of sludge;
[0013] The filter screen is placed inside the sludge cleaning box and located below the rolling collection shaft. It is used to filter out garbage and large stones on the surface of the sludge, preventing garbage and large stones from entering the intelligent control unit for sludge moisture content through the rolling collection shaft.
[0014] A further improvement is that a sludge scraper is installed under the filter screen. The sludge scraper is positioned in the forward direction of the sludge cleaning unit to perform secondary cleaning of the silt, ensuring the dredging effect while leveling the riverbed surface, thus ensuring that the riverbed surface is flat and aesthetically pleasing after dredging.
[0015] A further improvement is that the scraper blade is equipped with water-permeable holes, which are used to drain excess water in time during the secondary dredging process, so as to avoid the dredging effect being affected by water. At the same time, it reduces the amount of water flowing into the intelligent rolling drum of the mud storage tank, thereby saving the use of solidifying agent.
[0016] A further embodiment is that the rolling collection shaft includes a rolling shaft and blades;
[0017] The rolling shaft is connected to the power unit;
[0018] The blades are spirally wound around the rolling shaft;
[0019] The power unit drives the rolling shaft to rotate, which in turn drives the blades to rotate, thereby enabling the blades to clean and transport the sludge in situ.
[0020] The rolling collection shaft can collect sludge into the tail of the sludge cleaning box while cleaning, combining sludge removal and transportation into one process, reducing sludge pollution during transportation; at the same time, it greatly saves costs.
[0021] A further embodiment is that the sludge cleaning unit also includes a sludge volume control mechanism placed on the sludge cleaning box. The sludge volume control mechanism controls the speed and flow rate of the sludge entering the sludge moisture content intelligent control unit according to the amount of sludge collected in the sludge cleaning box.
[0022] A further solution is to include a mud moisture content intelligent control unit comprising a mud storage tank, a drainage mechanism, and a humidity sensor;
[0023] The mud storage tank is equipped with a water inlet and a water outlet;
[0024] The drainage mechanism is placed inside the mud storage tank, and a humidity sensor is installed on the drainage mechanism;
[0025] The sludge cleaning unit transports the collected sludge to the drainage mechanism via a connecting hose. A humidity sensor detects the humidity of the sludge in the drainage mechanism and transmits the data to the power unit. The power unit controls the operation of the drainage mechanism and the opening and closing of the inlet and outlet based on the data, thereby controlling the water content of the sludge in the drainage mechanism.
[0026] A further embodiment is that the drainage mechanism includes an intelligent rolling drum, which is placed inside the mud storage tank, and is equipped with a humidity sensor and a drainage hole.
[0027] The sludge cleaning unit transports the collected sludge to the intelligent rolling drum via a connecting hose. A humidity sensor detects the humidity of the sludge inside the intelligent rolling drum and transmits the data to the power unit. The power unit controls the operation of the intelligent rolling drum and the opening and closing of the inlet, outlet, and drain based on this data, thereby controlling the water content of the sludge inside the intelligent rolling drum.
[0028] A further proposed solution is that the slope spraying reinforcement unit includes a mud pump, a mixing tank, a solidified material storage tank, a solidified material control mechanism, a mixer, a pressure pump, and a rotary nozzle.
[0029] The mud pump pumps the sludge from the intelligent control unit for mud moisture content into the mixing tank.
[0030] The solidified material in the solidified material storage tank is input into the mixing tank through the solidified material control mechanism. The solidified material control mechanism automatically adjusts the amount of solidified material added into the mixing tank according to the amount of slurry in the mixing tank.
[0031] The mixer is placed in the mixing tank to mix the sludge and the solidified material, so that the sludge (slurry) and the solidifying agent are fully mixed to ensure the solidification effect;
[0032] The pressurized pump pumps the mixed sludge from the mixing tank into the rotary nozzle, which then sprays the mixed sludge onto the riverbank slope for slope reinforcement. The rotary nozzle allows for even spraying of the uniformly mixed sludge onto the slope, ensuring a tight bond between the sludge and the slope, depending on the actual site conditions.
[0033] The present invention also provides a method for in-situ river silt removal and slope reinforcement using the above-mentioned river silt removal and slope reinforcement device, which includes the following steps:
[0034] 1) Start the rolling collection shaft of the sludge cleaning unit. The entire device moves forward while collecting sludge and the collected sludge is transferred to the intelligent rolling drum in the sludge storage tank through the connecting hose.
[0035] 2) Start the scraper blades to perform a second dredging;
[0036] 3) The humidity sensor detects the humidity of the sludge inside the intelligent rolling drum and transmits the data to the power unit. The power unit controls the operation of the intelligent rolling drum and the opening and closing of the inlet, outlet and drain, thereby controlling the water content of the sludge inside the intelligent rolling drum.
[0037] 4) Once a certain amount of sludge has been collected in the intelligent rotating drum, start the mud pump to pump the sludge into the mixing tank;
[0038] 5) Based on the amount of sludge in the mixing tank, the solidification control mechanism delivers the corresponding amount of solidifying agent.
[0039] 6) Use the mixer in the mixing tank to thoroughly mix the sludge and solidifying agent evenly;
[0040] 7) The slurry mixed in the mixing tank is extracted by a pressure pump and transported to a rotary nozzle. The slurry is then sprayed evenly onto the slope surface through the rotary nozzle to reinforce the slope.
[0041] A further proposed solution is to control the water content of the sludge inside the intelligent rotating drum in step 3) as follows:
[0042] When the water content of the sludge in the intelligent rolling drum is lower than the set value, water is introduced into the sludge through the water inlet until the water content of the sludge is within the set value range.
[0043] When the sludge moisture content is higher than the set value, the power unit controls the intelligent rolling drum to rotate and opens the drainage hole and drain outlet to drain the sludge until the sludge moisture content is within the set value range.
[0044] The beneficial effects of this invention are as follows:
[0045] By setting up silt removal units and slope spraying reinforcement units, it is possible to remove river silt and reinforce river slopes at the same time, eliminating the need for manual river dredging and slope reinforcement, saving time and labor, and improving construction efficiency.
[0046] The silt removal unit cleans up the silt on the riverbed and makes the riverbed flat.
[0047] The water content of the sludge in the intelligent rolling drum is controlled by the intelligent control unit for sludge moisture content, ensuring that the sludge moisture content is the optimal moisture content for mixing with the solidifying agent, thereby ensuring the solidification effect of the sludge (sludge).
[0048] The silt (slurry) cleared from the riverbed is solidified by the slope spraying reinforcement unit, and the solidified slurry is sprayed onto the river slope to form a slurry slope protection with a certain strength, ensuring the stability of the river slope (slope protection).
[0049] Silt on the riverbed surface is collected by a rolling collection shaft, and the silt is removed and conveyed to the tail of the silt cleaning box by the rolling shaft and blades, thus realizing in-situ cleaning and transportation of silt.
[0050] The dual dredging method using a rolling collection shaft and a scraper ensures effective dredging while maintaining a beautiful and smooth riverbed surface after dredging.
[0051] By using a curing agent control mechanism to add appropriate curing agent according to the actual amount of mud, the ratio of mud to curing agent is ensured to be reasonable, avoiding waste of curing agent material and saving costs.
[0052] The filter screen can effectively control the entry of garbage and large stones in the sludge into the sludge cleaning box and subsequent processes, ensuring the normal operation of the device;
[0053] Using cleaned silt for slope reinforcement avoids the need for silt transportation and disposal, greatly saving costs.
[0054] The solidified mud sprayed onto the slope not only reinforces the slope but also provides various nutrients for the planting and growth of plants on the slope. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0063] Example 1

[0067] The silt cleaning unit 1 is used to clean silt from river channels. The silt cleaning unit 1 includes a silt cleaning box 1.1, a rolling collection shaft 1.2, and a filter screen 1.3. The silt cleaning box 1.1 is connected to the intelligent control unit 2 for sludge moisture content via a connecting hose 4, and has an opening at the bottom. The rolling collection shaft 1.2 is placed inside the silt cleaning box 1.1 and includes a rolling shaft and blades; the rolling shaft is connected to a power unit; the blades are spirally wound around the rolling shaft; the power unit drives the rolling shaft to rotate, which in turn drives the blades to rotate, thus enabling the blades to clean and transport the silt in situ. The rolling collection shaft 1.2 can collect the silt while cleaning it and bring it to the tail of the silt cleaning box 1.1, combining silt removal and transportation into a single process, reducing silt pollution during transportation, and significantly saving costs. The filter screen 1.3 is placed inside the silt cleaning box 1.1 and located below the rolling collection shaft 1.2. It is used to filter out garbage and large stones on the surface of the silt, preventing them from entering the intelligent control unit 2 for sludge moisture content through the rolling collection shaft 1.2. To perform secondary silt cleaning and ensure the dredging effect while leveling the riverbed surface 5, ensuring a smooth and aesthetically pleasing surface after dredging, a scraper 1.4 can be installed below the filter screen 1.3, positioned in the forward direction of the silt cleaning unit. To promptly drain excess water during secondary dredging by the scraper 1.4, preventing water from affecting the dredging effect and reducing water inflow into the intelligent rolling drum 2.2 of the sludge storage tank 2.1, thus saving on the use of solidifying agent, permeable holes 1.5 can be provided on the scraper 1.4.

The slurry pump 3.1 pumps the silt from the intelligent control unit 2 into the mixing tank 3.2. The solidified material control mechanism 3.4 is placed on the solidified material storage tank 3.3 and automatically adjusts the amount of solidifying agent added to the mixing tank 3.2 based on the amount of slurry in the mixing tank 3.2. The solidified material storage tank 3.3 contains the solidifying agent, which is input into the mixing tank 3.2 through the solidified material control mechanism 3.4. A mixer 3.5 is placed in a mixing tank 3.2 to mix the silt and solidifying agent, ensuring thorough mixing and effective curing. A pressure pump 3.6 is placed inside the mixing tank 3.2 to pump the mixed silt into a rotary nozzle 3.7, which sprays the mixed silt onto the riverbank slope for reinforcement. This invention uses the pressure pump 3.6 to evenly extract the mixture of silt (slurry) and solidifying agent, ensuring a good curing effect.
