Description

Technical Field

[0001] This invention relates to sludge cleaning devices, and more particularly to a solar-powered automatic sludge treatment device and method. Background Technology

[0002] Accumulation of silt at the bottom of rivers and lakes over a long period can cause the water to deteriorate and become foul-smelling. Furthermore, river and lake silt has a complex composition, containing large amounts of organic matter, heavy metals, and other toxic and harmful substances, which can be released under certain conditions, causing impacts and harm to the environment, ecosystem, and society.

[0003] At the same time, river and lake silt can be used as a new type of mineral resource that is rich in resources and can be utilized on a large scale, meeting the needs of natural resources such as soil and sand in economic construction and urban construction. However, if river and lake silt is completely removed, it will not only cause great ecological pollution to the bottom of the river and lake and its surroundings, but also waste this natural resource to a great extent.

[0004] To ensure that river and lake sediments can be successfully removed while maintaining ecological balance, and to enable the sediments to be continuously used in construction and other applications, it is necessary to develop targeted sediment treatment systems. Summary of the Invention

The power supply device is equipped with a solar concentrator and a battery, and supplies power to the dredging vessel, the sludge suction device, and the sludge treatment device. The sludge treatment device is equipped with a sludge filtration device, a water storage tank, and a vacuum pump. The water storage tank is located at the lower end of the sludge filtration device and is sealed to the sludge filtration device. The vacuum pump is located at the bottom end of the sludge filtration device.

[0007] The dredging vessel is equipped with a power wheel and a sensing device at its stern, and is connected to a microcontroller and a battery at its stern.

[0008] The sludge suction device includes a sludge suction pump and a sludge suction pipe. The sludge suction pump is fixedly connected to the top and bottom of the fixed bracket by rivets. The sludge suction pipe is fixedly connected to the telescopic rod by a ring buckle. One end of the sludge suction pipe is connected to the hull of the dredging vessel, and the other end is connected to the sludge suction pump. The fixed bracket and the telescopic rod are connected by a fixed hook located at the front end of the telescopic rod.

[0009] The telescopic rod includes fixed ends welded to both sides of the dredging vessel. The fixed ends are connected to the telescopic rod section through a connecting belt. The telescopic rod section is composed of several telescopic joints. The front end of the connecting belt is connected to the frontmost telescopic joint through a ring buckle.

The telescopic rod section is equipped with a locking block.

[0010] The telescopic rod is equipped with a mud level sensor at its front end, and the mud level sensor is connected to a microcontroller.

[0015] 1) Set up the course of the dredging vessel and install the operating platform, power supply equipment and sludge treatment equipment;

[0016] 2) Start the dredging vessel. After entering the dredging position under the command of the remote control terminal, lower the telescopic boom into the water. The mud level sensor detects the silt depth. The information is transmitted to the microcontroller.

[0020] Beneficial Effects: Compared with existing technologies, this invention has the following significant advantages: This invention utilizes solar energy as a power source to support the operation of the river and lake silt treatment device. It employs a remotely operable vessel-borne device, using telescopic rods on both sides of the vessel that extend to the bottom of the river or lake, along with a silt suction pump, to extract silt.

This enhances dredging efficiency and achieves scientific and ecological dredging. It is of great significance for realizing the regular automated removal and ecological dredging of river and lake silt, improving the ecological environment of rivers, lakes, and their surrounding areas, and promoting the effective utilization of silt, and has a very broad application prospect.

The remote control terminal 22 then sets the sludge depth and the vessel's travel speed and issues a command to start the rotating motor 435, causing the sludge suction pump 41 at the end of the telescopic boom 43 to sink. Once the sludge suction pump 41 reaches the preset sludge depth, the connecting belt 434 engages, the rotating motor 435 stops working, and the sludge suction pump 41 starts operating at its rated power. 1) The sludge is sucked into the sludge treatment device 5 through the suction pipe 42; 2) The vacuum pump 53 is started to initially pump out the sludge; 3) Repeat steps 2) to 3) until the sludge content in the sludge treatment device 5 reaches the warning position, the microcontroller 21 issues a warning, the suction pump 41 stops working, the rotating motor 435 starts to operate, and the suction pump 41 and the fixing device 44 are pulled up to the water surface.

[0030] Example 1:

[0031] The solar-powered automatic sludge treatment system of this embodiment includes a dredging vessel 1, on which a power supply device 3, a sludge suction device 4, and a sludge treatment device 5 are arranged. An operating platform 2 is located at the stern of the dredging vessel 1 and consists of a microcontroller 21, a remote control terminal 22, and a signal receiver processor 23, used to control the sludge suction device 4 and the sludge treatment device 5. The power supply device 3, consisting of a solar concentrator 31 and a battery 32, is located at the stern of the dredging vessel 1 and provides power to the dredging vessel 1, the sludge suction device 4, and the sludge treatment device 5. The sludge treatment device 5 includes a sludge filter 51, a water storage tank 52, and a vacuum pump 53. The sludge filter 51 is located in the center of the entire dredging vessel 1. The water storage tank 52 is located at the lower end of the sludge filter 51 and is sealed to it. The vacuum pump 53 is located at the front end of the sludge filter 51. The dredging vessel 1 is equipped with a power wheel 11 and a sensor 12 at its stern, and is connected to a microcontroller 21 and a battery 32. The power wheel 11 provides forward power to the dredging vessel 1, and the sensor 12 is used to determine the position of the dredging vessel 1 and adjust the vessel's position accordingly. The operating platform includes a microcontroller 21, a remote control terminal 22, and a signal receiving processor 23. The microcontroller 21 receives information from various sensors and transmits the terminal information to each sensor and sensing device. The remote control terminal 22 can receive data from the microcontroller in real time, process the data, and control the vessel. The signal receiving processor 23 is used to transmit data between the microcontroller and the remote control terminal, acts as a relay station, strengthens the signal strength, and is connected to the sensor 12 to determine the position of the dredging vessel 1. The silt suction device 4 includes a silt suction pump 41, a silt suction pipe 42, a telescopic rod 43, and a fixed bracket 44. The silt suction pump 41 is mounted on the fixed bracket 44, and the bottom and top of the fixed bracket 44 are riveted to the silt suction pump 41, so that the silt suction pump can reach a stable state when sucking bottom silt from the lake bottom. The silt suction pipe 42 and the telescopic rod 43 are fixedly connected to the telescopic rod 43 by a ring buckle. The lower end is connected to the outlet of the silt suction pump 41, and the upper end is connected to the hull of the dredging vessel 1, so that the bottom silt is directly sucked from the lake bottom to the silt filtration device 51. The fixed bracket 44 and the telescopic rod 43 are fixed together by the fixing hook 4310 at the front end of the telescopic rod.

[0032] The telescopic boom 43 comprises a fixed end 431, a telescopic boom section 432, a telescopic joint 433, a connecting belt 434, a rotating motor 435, a rotating shaft 436, a rotating wheel 437, a locking block 438, and a mud level sensor 439. The fixed end 431 is welded to both sides of the dredging vessel 1. The telescopic boom section 432 is composed of several telescopic joints 433. The fixed end 431 and the telescopic boom section 432 are connected internally through the connecting belt 434. The front end of the connecting belt 434 is connected to the front end of the telescopic joint 433 through a ring buckle. The rear end of the connecting belt 434 passes through the rotating wheel 437 and is fixed to the rotating motor 435, so that the front end of the telescopic joint is linked with the rotating wheel. The length of the connecting belt controls the descent height of the telescopic boom end, thereby achieving the effect of fixing the telescopic distance. The rotating motor 435 is connected to the battery 32 and the microcontroller 21. According to the instructions output by the microcontroller, it controls the movement of the connecting belt, thereby driving the front end of the telescopic joint and the position of the sludge pump to move. The locking block 438 is fixed on the telescopic rod end 432 and connected to the microcontroller. After receiving the termination signal from the remote control terminal, it stops the connecting belt from rotating and can be used to precisely control the descent depth of the telescopic rod. The front end of the telescopic rod 43 is equipped with a mud level sensor 439, which can measure the depth and thickness of the silt at the bottom of the lake. The mud level sensor 439 is connected to the microcontroller 21 so that the data can be transmitted to the microcontroller in real time. The sludge treatment device 5 can be set with one or more. The bottom and side walls of the sludge filtration device 51 are provided with multiple drainage holes 511, and the drainage holes 511 are inverted triangular cone structures. A filter column 512 is installed in the bottom drainage hole. The filter column 512 is hollow inside and has water-permeable holes 513 on its outer surface. The filter column 512 is connected to the bottom drainage hole 511 and is vertically distributed. The sludge filtration device 51 is provided with a porous wire mesh 514. The wire mesh and the drainage hole 511 are fixed by fastening holes and studs. The surface of the wire mesh 514 is covered with geotextile filter cloth 515. The geotextile filter cloth 515 has round holes corresponding to the filter column 512, so that the geotextile filter cloth covering the filter column overlaps and is fixed with the geotextile filter cloth of the drainage hole.

[0033] When the suction capacity of the sludge suction vessel is Q(m 3 The efficiency remains constant during operation, and the relationship between the vessel's forward speed v1 and the silt depth h can be expressed by the formula v1 = f(h)Q. In actual operation, the forward speed of the dredging vessel needs to be adjusted in real time according to the silt depth monitored by the silt level gauge to achieve the goal of ecological dredging. In practice, due to the limitation of the suction range of the suction pump, the dredging depth may be uneven in the direction of the vessel's movement. Therefore, in actual operation, the number of suction pumps and their distribution on the suction vessel can be reasonably arranged according to the suction radius and suction capacity of the suction pumps, and the lateral overlap rate and heading overlap rate of the suction vessel's forward path can be reasonably set.

[0034] Example 2:

[0035] The solar-powered automatic sludge treatment method of this embodiment includes the following steps:

[0036] 1) Install the operating platform 2, power supply device 3, and sludge treatment device 5 onto the dredging vessel, and set the dredging vessel's travel route using the remote control terminal 22. In this step, the filter column 512 needs to be fixed to the bottom drainage hole 511, and the wire mesh 514 needs to be laid on the drainage hole 511. It is then fastened and fixed by connecting it with the bolts through the fastening holes. Geotextile filter cloth 515 is laid on top of the wire mesh. The telescopic rod 43 is riveted to both sides of the hull, and the suction pipe is fixed to the telescopic rod 43 by passing through the ring buckle on the telescopic rod 43. The upper end is connected to the sludge filter device 51, and the lower end is connected to the suction pump 41. The suction pump 41 is then fixedly connected to the fixing device 44 using relevant technology, and the front end of the telescopic rod 43 is connected to the fixing device 44 by the ring buckle.

[0037] 2) Start the dredging vessel 1. After the vessel enters the designated dredging location according to the pre-set route on the remote control terminal 2, it stops moving forward and begins dredging work. In this step, the telescopic boom 43 extends 50cm underwater, so that the mud level sensor 439 is below the water surface. The mud level sensor 439 senses the depth and thickness of the silt and transmits the data to the microcontroller 21. The remote control terminal 22 sets the dredging depth and the vessel's travel speed. Then, the dredging vessel 1 travels at the set speed, and the microcontroller 21 issues a command to start the rotating motor 435. The connecting belt starts rotating, causing the front end of the telescopic boom 43 and the sludge pump 41 to sink. After the sludge pump 41 reaches the preset silt depth, the rotating motor 435 stops working, and the locking block locks the connecting belt. The sludge pump 41 starts operating at its rated power, sucking the silt into the silt filter device 51 through the suction pipe 42. In this step, when the sludge suction capacity Q(m) of the dredging vessel is... 3 The efficiency remains constant during operation. The relationship between the ship's forward speed v1 and the silt depth h can be expressed by the formula v1=f(h)Q.

[0038] In practice, the speed of the dredging vessel needs to be adjusted in real time based on the silt depth monitored by the mud level gauge to achieve the goal of ecological dredging. In actual operation, due to the limitation of the suction range of the suction pumps, the dredging depth may be uneven along the vessel's forward direction. Therefore, in practice, the number of suction pumps and their distribution on the dredging vessel should be rationally arranged according to their suction radius and suction capacity, and the lateral overlap rate and heading overlap rate of the dredging vessel's forward path should be reasonably set. Simultaneously, the mud level sensor detects the silt depth in real time and transmits the data to a microcontroller, allowing for remote control interruption and real-time adjustment of the dredging vessel's forward speed and dredging depth.

[0039] 3) After the sludge is transported to the sludge dredging tank, start the vacuum pump 53 to perform preliminary pumping of the sludge, accelerate the filtration of water in the sludge in the sludge filtration device 51, and allow the sludge in the sludge filtration device 51 to be dried in the sunlight.

[0040] 4) Repeat steps 2) to 3). When the sludge content in the sludge filtration device 51 reaches the warning level, the microcontroller 21 issues a warning, the sludge suction pump 41 stops working, and the rotating motor 435 starts operating, pulling the sludge suction pump 41 and the fixing device 44 to the water surface. The dredging vessel 1 then sails to the shore under the command of the remote control terminal 22. Upon reaching the shore, the geotextile filter cloth 515 is loosened by unfastening the fastening device, allowing the sludge on the geotextile filter cloth 515 to be removed and stored or used directly. The sludge wastewater containing heavy metals in the water storage tank 52 undergoes secondary treatment.

[0041] 5) Repeat steps 1) to 4) until all dredging tasks along the ship's route are completed.

[0042] Effect Analysis:

[0043] This invention utilizes a solar concentrator and battery to collect sunlight for power, avoiding excessive electricity consumption and leveraging large usable areas of the lake surface. The device automatically adjusts the depth of the underwater sludge pump by connecting a microcontroller, a mud level sensor, and a rotating motor, improving sludge removal efficiency while meeting ecological dredging requirements. After the river and lake sludge is sucked onto the boat, it is directly filtered. The filtered sludge solidifies into blocks under sunlight, making it easy to remove and use. Simultaneously, the sludge discharged into the water contains heavy metals and cannot be directly discharged; it is stored in a storage tank to prevent secondary pollution of the river and lake. This invention is easy to install and disassemble, can be carried on a boat, or directly installed on a biological pot for sludge removal in a specific area, achieving automated sludge removal and collection. This invention uses a mud level sensor on a telescopic rod to determine the depth and thickness of river and lake silt, as well as the content of silt at the bottom of the lake, facilitating ecological dredging. Through the connection between the sensor and the microcontroller via the power wheels on both sides of the hull, the hull can be remotely controlled, saving manpower and resources, and enabling dredging to be carried out at fixed points and along fixed routes.
