Description

Technical Field

[0001] This utility model belongs to the technical field of reservoir aquaculture equipment, specifically a hanging net device for reservoir aquaculture. Background Technology

[0002] With the development of large-scale aquaculture technology, the reservoir hanging net aquaculture model, while improving water utilization, faces two major technical challenges: water temperature stratification and escape prevention.

[0003] In existing technologies, such as the intelligent temperature control system for underwater cage aquaculture disclosed in Chinese patent document CN210017514U, water temperature is regulated by combining a bottom heat exchanger with a surface circulation pump. However, this device relies on external energy for heating, resulting in high energy consumption and an inability to dynamically balance vertical temperature differences. Furthermore, its spiral heat exchange coil arrangement is prone to localized water temperature fluctuations when the water flow is disturbed, making it difficult to meet the fish's need for a stable temperature environment. Additionally, the floats are generally positioned along the circumference of the hanging net, posing a risk of fish jumping and escaping, thus causing losses.

[0004] The aforementioned existing technologies generally suffer from the following drawbacks: 1) Water temperature control relies on external heating equipment, resulting in high operating costs; 2) There is a risk of fish jumping and escaping.

[0005] Based on the above-mentioned technical problems, this application provides a hanging net device for reservoir aquaculture. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hanging net device for reservoir aquaculture, which solves the technical problems of water temperature control relying on external heating equipment, high operating costs, and the risk of fish jumping and escaping.

[0007] The solution adopted in this utility model is: a hanging net device for reservoir aquaculture, characterized in that it includes:

[0008] Aquaculture hanging net, wherein the aquaculture hanging net is a box structure with an open top and a number of filter holes evenly distributed on the inner wall;

[0009] A constant temperature component is fixedly installed at the bottom of the aquaculture hanging net. The constant temperature component includes a pump body, a bottom pipe, a top pipe, and several layout pipes. The top pipe is fixedly installed at the top of the aquaculture hanging net, the pump body is installed at the bottom of the aquaculture hanging net, the bottom pipe is a retractable pipe that connects the pump body and the top pipe, and several layout pipes are spaced apart along the length of the top pipe and are connected to the top pipe. Several atomizing water spray nozzles covering the inside of the aquaculture hanging net are provided on the layout pipes.

[0010] The floats are arranged in several places along the circumference of the aquaculture hanging net. The aquaculture hanging net is equipped with an adjustment component that cooperates with the floats to adjust the height of the floats.

[0011] Preferably, the pump body and the bottom pipeline have two, and the pump body is provided with a deep water pump, and the bottom of the breeding net is provided with a mounting plate connected with the pump body.

[0012] The double-pump-body design (deep water pump) significantly improves the water circulation efficiency, and when a single pump fails, the other pump can still maintain operation, ensuring system reliability. The deep water pump directly extracts low-temperature water from the bottom layer, enhancing the temperature control effect and avoiding the influence of high-temperature water on the surface layer on the breeding area. The bottom mounting plate facilitates quick disassembly and maintenance of the pump body, reducing maintenance difficulty. When in use, the pump body and the mounting plate are separated, and under the action of the telescopic pipeline and the gravity of the pump body, they sink to the bottom of the pool. The bottom of the pool and the top form a temperature difference, and the cooling effect is significant. The disassembly method can use a magnet on the bottom of the mounting plate and a magnet suction plate on the pump body, or use a bolt to disassemble and install, the main purpose is to facilitate storage.

[0013] Preferably, the atomizing nozzle is arranged upward at an inclination angle of 30°, the nozzle spacing is 2-3 times the pipe diameter, and the nozzles of adjacent pipelines are arranged in a staggered manner.

[0014] The 30° upward atomizing nozzle design makes the water flow form a spiral upward flow, expanding the water mixing range; the nozzle spacing is 2-3 times the pipe diameter and arranged in a staggered manner, ensuring the uniformity of the water temperature in the breeding area and avoiding local temperature differences. The actual measurement data shows that this structure can improve the water temperature uniformity by 40%, which is better than the traditional parallel nozzle design.

[0015] Preferably, the adjusting assembly comprises:

[0016] The net floating frame is arranged at the top of the breeding net.

[0017] The floating plate is arranged at the bottom of the net floating frame, the net floating frame is threadedly connected with an adjusting screw rod, one end of the adjusting screw rod is threadedly connected with the floating plate, the other end is provided with an adjusting block, and the floating plate is provided with a plurality of floating balls along the circumference.

[0018] The guide piece is arranged between the floating plate and the breeding net.

[0019] The thread connection between the adjusting screw rod and the adjusting block realizes stepless adjustment of the height of the floating ball, and a single person can complete the operation. The guide piece limits the moving direction of the floating plate to avoid the twisting of the net caused by lateral displacement and improve the adjustment stability.

[0020] Preferably, the guide piece comprises a guide rod and a limiting plate, the floating plate is slidably connected with the guide rod, the guide rod is fixedly connected with the net floating frame, the limiting plate is fixedly connected with the guide rod away from the net floating frame.

[0021] The combination of the guide rod and the limiting plate ensures that the floating plate smoothly slides along the vertical direction, prevents inclination or deviation under the impact of wind and waves, and limits the maximum stroke of the floating plate to avoid excessive adjustment and structural damage, thereby prolonging the service life of the device.

[0022] Preferably, the floating plate is provided with two L-shaped floating plates, which are located at the bottom of the net floating frame and are symmetrically arranged at the center of the net.

[0023] The L-shaped floating plate is symmetrically arranged at the center, thereby increasing the floating force acting area and improving the overturning resistance of the net cage.

[0024] Preferably, the L-shaped floating plate is made of glass fiber reinforced plastic, and the plate body is internally provided with a honeycomb-shaped floating cavity and a plurality of weight-reducing through holes.

[0025] Preferably, the net floating frame is made of aluminum alloy profile, the frame body is internally filled with closed-cell foam plastic, and the bottom surface of the floating frame is provided with a corresponding anti-collision buffer strip.

[0026] The aluminum alloy floating frame has excellent corrosion resistance, the closed-cell foam plastic filling enhances the overall floating force, the anti-collision buffer strip is made of elastic material and can absorb more than 80% of the impact force, thereby reducing the wear between the floating plate and the floating frame and prolonging the service life of the equipment.

[0027] Beneficial effects:

[0028] I. Water temperature regulation advantage: low-temperature water in the deep layer is extracted by the bottom deep water pump, and is sprayed upward at an angle of 30° through the atomizing nozzle of the top pipeline to form a three-dimensional water circulation system. Compared with the traditional plane heating, the stress reaction of fish caused by local high temperature is avoided, and the device is especially suitable for cold-water fish breeding. Since fish can be continuously fed at 15-20℃, the device is beneficial to the growth of fish.

[0029] II. Flexible adjustment capability: the screw rod and the floating plate are screw-connected, so that stepless adjustment of the floating ball within a certain range can be realized. The guide rod limiting structure ensures the vertical movement precision of the floating plate, and the position of the floating ball can be adjusted according to the type of fish through the adjusting assembly, so that the net floating frame is lifted, the net is pulled up, fish jumping out of the net is avoided, and economic loss is caused.
