Description

Technical Field

[0001] This utility model relates to the field of aquaculture pond dredging technology, specifically to a bottom suction device for flowing water aquaculture ponds. Background Technology

[0002] In aquaculture, flow-through aquaculture ponds are a common type of pond. After aquatic products have been cultured in these ponds for a period of time, a significant amount of sludge and sediment accumulates at the bottom, requiring timely cleaning. Otherwise, it will negatively impact the water quality and consequently affect the aquaculture process. Currently, existing technology typically uses a sludge pump to remove the sludge from the flow-through aquaculture pond. The pump's inlet is connected to a sludge suction pipe, and its outlet is connected to a discharge pipe. By placing the free end of the sludge suction pipe at the bottom of the pond, the sludge and sediment can be suctioned out.

[0003] However, sludge and mud are not always thin; in many cases, sludge is quite viscous. This makes it difficult for the sludge pump to extract the sludge, and the viscous sludge can also easily clog the suction pipe, thus increasing the difficulty of cleaning. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a bottom suction device for a flowing water aquaculture pond. It has a structure with its own sludge crushing and stirring mechanism, which can stir, crush and dilute the sludge before suction, making the sludge cleaning work at the bottom of the pond smoother and more efficient.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: The bottom suction device for the flowing water aquaculture pond includes: The sludge suction port, suction hose, and sludge suction pump; the sludge suction port is a cylindrical structure with an open bottom, and the top is connected to the sludge suction pump via the suction hose. A handle rod is also fixed to the top of the sludge suction port. The mixing and crushing mechanism is located inside the sludge extraction port and is used to mix and crush the sludge.

[0006] As an improvement, the stirring and pulverizing mechanism includes a stirring and pulverizing drive mechanism, a cutter shaft, and pulverizing blades; multiple pulverizing blades are evenly fixed on the cutter shaft, and after the cutter shaft and pulverizing blades are evenly arranged in the circumferential direction within the sludge suction port, they are driven by the stirring and pulverizing drive mechanism to perform synchronous rotational motion and revolution motion around the circumference of the sludge suction port.

[0007] As an improvement, the mixing and pulverizing mechanism includes a motor, a rotating shaft, a disc, a cylindrical shaft, a fixed gear, and a movable gear. The cylindrical shaft passes through and is rotatably connected to the top wall of the sludge extraction port. After the rotating shaft passes through and is rotatably connected inside the cylindrical shaft, its top end is connected to a motor fixedly mounted on the top of the sludge extraction port, and its bottom end is fixedly connected to the disc. The top of each cutter shaft passes through and is rotatably connected to the disc, and a movable gear is fixedly mounted on the top end of each cutter shaft. A fixed gear, which meshes with each movable gear, is sleeved and fixed at the bottom of the cylindrical shaft. This mechanism can effectively and efficiently mix and pulverize the sludge and wastewater at the bottom of a flowing water aquaculture pond.

[0008] As an improvement, a threaded post is fixed to the top of the suction port, and a threaded slot is pre-drilled on the bottom surface of the handle rod, which is threaded onto the threaded post through the threaded slot. This allows the handle rod to be easily installed and removed, and after disassembly, this new design is easier to store, load, and transport.

[0009] It is worth mentioning that the sludge pump and motor in this technical solution are both existing devices known to the public, and the motor is an existing waterproof motor device.

[0010] The advantages of this utility model compared with the prior art are as follows: 1. When using this new type of equipment, the hand handle is used to move the sludge suction port at the bottom of the flowing water aquaculture pond. With the cooperation of the sludge suction pump, the sludge at the bottom of the flowing water aquaculture pond can be sucked out, thereby achieving the effect of sludge removal and pollution control.

[0011] 2. This new invention incorporates a mixing and pulverizing mechanism within the sludge extraction port, which effectively pulverizes and mixes the sludge at the bottom of the flowing water aquaculture pond. This thins the viscous sludge, enabling smoother and more efficient sludge removal. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] The bottom suction device for the flowing water aquaculture pond includes: The sludge suction port 1, the sludge suction hose 2, and the sludge suction pump (not shown in the figure) are all included. The sludge suction port 1 is a cylindrical structure with an open bottom, and the top is connected to the sludge suction pump through the sludge suction hose 2. The top of the sludge suction port 1 is also fixed with a handle rod 3 and a threaded post 12. The bottom surface of the handle rod 3 has a threaded groove 13, and the handle rod 3 is threaded onto the threaded post 12 through the threaded groove 13. The top of the handle rod 3 is covered with an anti-slip sleeve 14, which is a silicone sleeve. The mixing and pulverizing mechanism includes a motor 6, a rotating shaft 7, a disc 8, a cylindrical shaft 9, a fixed gear 10, a movable gear 11, a cutter shaft 4, and pulverizing blades 5. Multiple pulverizing blades 5 are evenly fixed on the cutter shaft 4, and the cutter shaft 4 and the pulverizing blades 5 are evenly arranged circumferentially within the sludge extraction port 1. The cylindrical shaft 9 passes through and is rotatably connected to the top wall of the sludge extraction port 1. The rotating shaft 7 passes through and is rotatably connected inside the cylindrical shaft 9, and its top end is driven by the motor 6, which is installed and fixed at the top of the sludge extraction port 1. The bottom end is fixedly connected to the disc 8. The top end of each cutter shaft 4 passes through and is rotatably connected to the disc 8. After the movable gear 11 is fixed to the top end of the cutter shaft 4, the bottom end of the cylindrical shaft 9 is fitted with and fixed with a fixed gear 10 that meshes with each movable gear 11. The pulverizing blades 5 on each cutter shaft 4 avoid each other, and their mixing ranges partially overlap.

[0021] In the specific implementation of this embodiment: like Figure 1 As shown, the hand-held handle 3 controls the movement of the sludge suction port 1 at the bottom of the flowing water aquaculture pond. Through the operation of the sludge suction pump, the sludge and sludge at the bottom of the pond can be suctioned. Simultaneously, the motor 6 drives the disc 8 to rotate. Through the cooperation of the fixed gear 10 and the movable gear 11, the cutter shaft 4 and the pulverizing blades 5 can revolve around the rotating shaft 7 while also rotating on their own axis. This effectively thins the sludge and sludge at the bottom of the pond, making the sludge suction work smoother and more efficient.
