Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and specifically discloses a fishpond counter-current bucket water circulation improvement device. Background Technology

[0002] A fishpond counter-current water circulation system is a device used to improve water quality and circulation in fishponds. It promotes water flow and exchange by installing a counter-current water system within the fishpond, thereby improving water quality and the growth environment for fish. A common counter-current water system involves a pump drawing water from one end of the fishpond to the other, creating a counter-current flow. A counter-current water system typically consists of multiple water units, each with an inlet and an outlet.

[0003] For example, the utility model patent CN207305794U discloses a high-breeding-rate fish pond. The pond is divided into multiple elongated rearing ponds by parallel partitions. Each rearing pond contains a spawning nest for the fish. A working tank for heating water is located outside the pond. A water pump is connected to the pond to deliver water to the working tank. A hot water main pipe is located at the other end of the working tank to deliver hot water into the pond. A feeding hole for adding oxytocin is located at the top of the working tank. A temperature sensor for measuring water temperature is located inside the working tank. Through the combined use of the heating resistor, temperature sensor, and plastic greenhouse structure within the working tank, the water temperature is maintained at the optimal breeding temperature, enabling winter breeding. A drive plate allows for flexible and reasonable allocation of space between the spawning and rearing ponds. Water circulation through cold and hot water branch pipes at both ends of the rearing ponds stimulates gonadal development in the fish, shortening the development cycle. Regular water changes are achieved through a water exchange valve and a position meter, improving water quality. Currently, fish ponds improve water quality through counter-current bucket water circulation. Conventional circulation methods primarily involve pumping water from one end to the other, with filtration occurring during the process. While single-cycle water circulation can increase water flow and promote water exchange, resulting in a more even distribution of oxygen, nutrients, and waste and improving water quality, it is difficult to achieve the required water quality improvement when there are a large number of fish. Therefore, it is necessary to further enhance the structure of the water system to improve the quality of the counter-current bucket water circulation process. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a fish pond counter-current bucket water circulation improvement device to solve the problem that when the number of fish is large, it is difficult to achieve the water quality improvement standard by using a single circulation method.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fish pond counter-current bucket water circulation improvement device, including a water circulation mechanism, an aeration mechanism is provided on the upper end of one side of the water circulation mechanism, and a water treatment mechanism is also provided on the outer side of the water circulation mechanism.

[0006] Furthermore, the water circulation mechanism includes a water tank, a waste discharge port is provided through the lower back of the water tank, a valve is provided on the surface of the waste discharge port, a water pumping pipe is provided through one end of the water tank, and a filter head is provided at one end of the water pumping pipe inside the water tank.

[0007] A water pump is installed at one end of the water tank. A water supply pipe is installed at the outlet end of the water pump. A pipe sleeve is installed through the surface of the water supply pipe. A support frame is installed on the outer wall of the pipe sleeve. A water inlet pipe is installed at the end of the water tank away from the water pump. A connection port is installed at the other end of the water supply pipe.

[0008] Furthermore, a filter cylinder is provided at the lower end of the connector, a plate frame is provided inside the filter cylinder, a support block is provided on the inner wall of the filter cylinder, and the lower end of the plate frame is supported on the upper end of the support block.

[0009] Furthermore, two symmetrically distributed positioning rings are respectively provided at the upper end of the plate frame. Positioning pins slide through the inside of the positioning rings, and springs are wound around the surface of the positioning pins. Positioning grooves are opened on the inner wall of the filter cylinder, and the end of the positioning pin away from the spring is inserted into the inside of the positioning groove.

[0010] Furthermore, the aeration mechanism includes a side platform that covers the upper side of the pool. Several sets of air pumps are distributed above the side platform. The air inlet of the air pump is covered with a dustproof net, and the air outlet of the air pump is provided with an aeration pipe. The other end of the aeration pipe is inserted into the interior of the water inlet pipe.

[0011] Furthermore, the water treatment mechanism includes a base, a transition pipe is provided at the outward end of the inlet pipe, a second water pump is provided above the base, an outlet pipe is connected to the inlet flange of the second water pump, a treatment box is provided above the base, and a box cover is provided at the top of the treatment box.

[0012] Furthermore, the interior of the processing box is equipped with a filter cover, the surface of which has a through hole penetrating its interior. An ultraviolet lamp is installed through one side of the processing box, and a waste discharge port two is installed through the other side of the processing box. A valve two is installed on the surface of the waste discharge port two.

[0013] Furthermore, a universal interface is provided through one side of the box cover, and a valve is provided on the surface of the universal interface;

[0014] A bearing is installed through one side of the processing box, and a stirring shaft is installed through the bearing. Several stirring rods are installed inside the stirring shaft. A motor is installed outside the processing box, and a drive shaft is installed inside the motor. One end of the drive shaft is fixedly connected to the stirring shaft through a coupling.

[0015] The working principle and beneficial effects of this solution are as follows: 1. When it is necessary to improve the circulation of water in the fish pond by counter-current bucket water circulation, the power of water pump one is turned on, so that water pump one can achieve a water pumping effect, so that the water in the pond can be pumped out through the water pump pipe, and then sent into the water supply pipe through water pump one, and enter the filter cylinder for filtration through the connection port. In the initial stage of water pumping, the basic filtration through the filter head can filter particles and larger impurities to prevent them from clogging water pump one. After entering the filter cylinder, the activated carbon filter can not only further filter fine particles, but also treat the odor in the water and reduce the circulation and breeding of odor. Finally, the filtered water is sent into the treatment tank for further treatment and return.

[0016] 2. As described in 1, when the water enters the treatment tank, the ultraviolet lamp is switched on, and ultraviolet light is emitted through the ultraviolet lamp to eliminate bacteria and viruses in the water, thereby achieving a further purification effect. Through the filter cover structure inside the treatment tank, it is possible to prevent the debris generated inside the treatment tank from being discharged together during the backflow. The power of the second water pump is turned on, and the sterilized water is drawn out through the outlet pipe and sent into the transition pipe through the second water pump. Finally, it flows back into the water tank through the inlet pipe. In order to ensure the oxygen content of the backflow water, the power of the air pump is turned on, so that the air pump can draw in external air and send it into the aeration pipe, so that the aeration holes at the end of the aeration pipe can aerate at the outlet of the inlet pipe, thereby increasing the gas exchange effect.

[0017] 3. As described in section 2, when nutrient solution or powder is needed, it can be dispensed into the treatment tank through a universal interface. The purpose of dispensing it into the treatment tank is to sterilize it through ultraviolet lamps, reducing the bacteria carried in the nutrient solution or powder. In order to improve the dispersion effect of the nutrient solution or powder with the water in the treatment tank, the power of the motor is turned on. Driven by the motor, the rotating shaft can drive the stirring shaft to rotate, thereby causing the stirring rod to rotate, which can uniformly mix the water with the nutrient solution or powder.

The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0036] In practice

[0037] When it is necessary to improve the water circulation in the fish pond by counter-current bucket-type water circulation, turn on the power of water pump 15 so that water pump 15 can perform a water pumping effect, so that the water in the pond 10 can be drawn out through the water pump pipe 13, and then sent into the water supply pipe 16 through the water pump 15, and enter the filter cylinder 1001 for filtration through the connection port 110. In the initial stage of water pumping, the basic filtration through the filter head 14 can filter out particles and larger impurities to prevent them from clogging the water pump 15. After entering the filter cylinder 1001, the activated carbon filter screen 1004 can not only further filter out fine particles, but also treat the odor in the water and reduce the circulation and breeding of odor. Finally, the filtered water is sent into the treatment tank 34 for further treatment and return.

[0038] When the water enters the treatment tank 34, the switch of the ultraviolet lamp 38 is turned on. The ultraviolet light emitted by the ultraviolet lamp 38 can eliminate bacteria and viruses in the water, thereby achieving a further purification effect. Through the filter cover 36 structure inside the treatment tank 34, the impurities generated inside the treatment tank 34 can be prevented from being discharged together during the backflow. The power of the second water pump 32 is turned on, and the sterilized water can be drawn out through the outlet pipe 33 and sent into the transition pipe 31 through the second water pump 32. Finally, it flows back to the water tank 10 through the inlet pipe 19. In order to ensure the oxygen content of the backflow water, the power of the air pump 21 is turned on, so that the air pump 21 can draw in the outside air and send it into the aeration pipe 23, so that the aeration holes at the end of the aeration pipe 23 can aerate at the outlet of the inlet pipe 19, thereby increasing the gas exchange effect.

[0039] When nutrient solution or powder is needed, it can be dispensed into the treatment tank 34 through the universal interface 3001. After being dispensed into the treatment tank 34, it can be sterilized by the ultraviolet lamp 38 to reduce the bacteria carried in the nutrient solution or powder. In order to improve the dispersion effect of nutrient solution or powder with water in the treatment tank 34, the power supply of motor 3005 is turned on. Driven by motor 3005, the rotating shaft can drive the stirring shaft 3004 to rotate, thereby causing the stirring rod 3006 to rotate, which can uniformly mix the water with the nutrient solution or powder.

[0040] When it is necessary to periodically clean the impurities attached to the activated carbon filter 1004 or to completely replace the activated carbon filter 1004, the positioning pin 1006 is pulled, which allows the spring 1007 to be stretched. This allows the positioning pin 1006 to slide away from the inside of the positioning groove 1008, thereby enabling the plate frame 1002 to slide away from the filter cylinder 1001, and thus enabling the removal of the activated carbon filter 1004.

It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
