Description

Technical Field

[0001] This invention relates to an underwater dredging device for aquaculture areas with a deployable protective cover, belonging to the field of underwater dredging technology. Background Technology

[0002] In aquaculture waters, where fish are raised at high densities, excess feed and fish excrement settle to the bottom and accumulate during feeding, causing the silt layer to increase by tens of centimeters per year. Over time, this silt can reach a thickness of over 1 meter in some areas. The decay of this nutrient-rich organic matter makes the water turbid and smelly, promotes algae growth, microbial proliferation, and the spread of diseases. Therefore, regularly removing silt can effectively reduce the risk of fish diseases.

[0003] Existing underwater dredging equipment uses a dredging machine to agitate the silt at the bottom of the water, turning it into mud. The mud is then transported to the shore by a suction pump. However, any mud that is not completely removed diffuses into the water, which increases the turbidity of the water.

[0004] Based on this, in order to solve the above technical problems, this case proposes an underwater dredging device for aquaculture waters with a deployable protective cover. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide an underwater dredging device for aquaculture waters with a deployable protective cover.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is: an underwater dredging device for aquaculture waters with an expandable protective cover, comprising a body, a suspension mechanism at the top of the body, a sludge suction mechanism and a stirring mechanism at the bottom of the body, and a protective cover mechanism on the outer periphery of the body.

[0007] Preferably, the sludge suction mechanism includes a sludge suction pump fixedly connected to the middle position of the bottom of the machine body, the sludge suction inlet of the sludge suction pump facing downwards, and the sludge outlet of the sludge suction pump connected to a sludge discharge pipe.

[0008] Preferably, the stirring mechanism includes several sets of stirring components evenly distributed on the outer periphery of the sludge suction mechanism.

[0009] Preferably, each of the stirring components includes a stirring motor fixedly connected to the machine body, and the output shaft of the stirring motor is vertically downward and fixedly connected to a rotating blade.

[0010] Preferably, the protective cover mechanism is an opening and closing protective cover mechanism.

[0011] Preferably, the protective cover mechanism includes several V-shaped frames, which are evenly distributed around the outer periphery of the body, and a flexible cover is fixedly connected between two adjacent frames. The inner ends of the frame are all hinged to the outer periphery of the machine body. The sides of the frame near the inner ends are all hinged to connecting rods. A lifting seat is provided on the machine body. The other ends of the connecting rods are all hinged to the outer periphery of the lifting seat.

[0012] Preferably, the suspension mechanism includes a plurality of lugs for connecting the suspension ropes, and the lugs are all fixedly installed at the top of the lifting seat.

[0013] Preferably, the machine body is provided with a lifting channel for vertically mounting the lifting seat, and the lifting seat is connected to the machine body by a screw jack driven by a motor.

[0014] Preferably, the motor is fixedly connected to the inner bottom of the lifting channel, and the ball nut screwed onto the screw of the screw jack is fixedly connected to the bottom of the lifting seat.

[0015] Preferably, a camera is installed on the body, and the camera's field of view is located within the coverage area of ​​the protective cover mechanism.

[0016] Compared with existing technologies, this invention has the following advantages: During cleaning operations, the underwater dredging device for aquaculture areas with a deployable protective cover covers the dredging area, and the stirring mechanism rotates rapidly, agitating the sludge into a slurry state. The suction mechanism then draws the slurry into the pump and discharges it, thereby achieving comprehensive and efficient sludge removal from aquaculture areas. This effectively reduces the labor intensity of workers and significantly shortens the cleaning time. The protective cover effectively prevents the spread of slurry, reducing the extent to which incompletely removed slurry diffuses into the water and preventing excessive turbidity. Furthermore, the protective cover effectively reduces the probability of fish and other organisms being strangled or injured in the dredging area, allowing underwater dredging operations to be carried out in aquaculture areas, greatly improving both aquaculture and dredging efficiency.

The top of the body is provided with a suspension mechanism, the bottom of the body is provided with a sludge suction mechanism and a stirring mechanism, and the outer periphery of the body is provided with a protective cover mechanism.

[0026] In this embodiment of the invention, the sludge suction mechanism includes a sludge suction pump 2 fixedly connected to the middle position of the bottom of the machine body. The sludge suction inlet of the sludge suction pump faces downward, and the sludge outlet of the sludge suction pump is connected to a sludge discharge pipe 3.

[0027] In this embodiment of the invention, the stirring mechanism includes several sets of stirring components evenly distributed on the outer periphery of the mud suction mechanism.

[0028] In this embodiment of the invention, each stirring assembly includes a stirring motor 4 fixedly connected to the machine body, and the output shaft of each stirring motor is vertically downward and fixedly connected to a rotating blade 5.

[0029] In this embodiment of the invention, the protective cover mechanism is an opening and closing type protective cover mechanism.

[0030] In this embodiment of the invention, the protective cover mechanism includes several V-shaped skeletons 6, which are evenly distributed around the outer periphery of the body, and a flexible cover 7 is fixedly connected between two adjacent skeletons. The inner ends of the frame are all hinged to the outer periphery of the machine body. The sides of the frame near the inner ends are all hinged to connecting rods 8. A lifting seat 9 is provided on the machine body. The other ends of the connecting rods are all hinged to the outer periphery of the lifting seat.

[0031] In this embodiment of the invention, the suspension mechanism includes a plurality of lugs 11 for connecting the suspension rope 10, and the lugs are all fixedly installed at the top of the lifting seat.

[0032] In this embodiment of the invention, the machine body is provided with a lifting channel 12 for vertically mounting the lifting seat, and the lifting seat is connected to the machine body by a screw jack 14 driven by a motor 13.

[0033] In this embodiment of the invention, the motor is fixedly connected to the inner bottom of the lifting channel, and the ball nut 16 screwed onto the lead screw 15 of the screw jack is fixedly connected to the bottom of the lifting seat.

This allows workers to observe and determine whether an organism is encased under the cover through the camera, improving operational safety.

[0035] In this embodiment of the invention, the working principle of the underwater dredging device for aquaculture areas with a deployable protective cover is as follows: The device is lowered to the work area by suspending it with a hoisting rope from the boat. Workers first observe the vicinity of the target dredging area for any organisms using a camera. Once confirmed to be free of organisms, the lifting platform descends, unfolding the cover to cover the target dredging area. Workers again observe through the camera to determine if any organisms are trapped inside the cover. After confirming no trapped organisms, the sludge suction and stirring mechanism is activated. The stirring mechanism rotates rapidly, turning the sludge into a slurry. The suction mechanism draws the slurry into the pump and discharges it, thus achieving comprehensive and efficient sludge removal from the aquaculture area. This effectively reduces the labor intensity of workers and significantly shortens the cleaning time. The cover effectively prevents the slurry from spreading, reducing the amount of incompletely removed slurry entering the water and preventing excessive turbidity. Furthermore, the cover effectively reduces the probability of fish and other animals entering the dredging area being strangled or injured, allowing underwater dredging operations to be carried out in aquaculture areas, greatly improving both aquaculture and dredging efficiency.
