Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture equipment, in particular to a cleaning mechanism for the central pipe of a fish pond. Background Art

[0002] Fishermen achieve high yields in fish farming by means of releasing fry, feeding, adjusting water quality, oxygenation, etc. High-density aquaculture is one of the trends in modern fishery aquaculture. In high-density aquaculture, water quality is one of the most basic environmental factors in fish farming and also one of the main factors affecting fish growth. The accumulation of residual bait and fish feces in the fish pond water will affect the growth and health status of fish. In addition, the change of water quality will also affect the appetite and activity of fish. Therefore, maintaining the cleanliness and stability of water quality is the key to fish farming. In order to keep the water clean, installing a water quality filter is one of the necessary conditions. The water quality filter can not only promote the circulation of water in the pool, but also filter feces, sediment, etc. in the water during the flowing process, so as to ensure that the water re-entering the fish pond remains clean.

[0003] During the breeding process, it is necessary to regularly clean the central pipe filter screen of the fish pond water quality filter. The traditional cleaning method uses methods such as manually holding cleaning tools or high-pressure water guns to remove the dirt in the central pipe filter screen. Such an operation is very inconvenient, and at the same time, the labor cost is high. It is also necessary to remove the central pipe in the fish pond, which has adverse effects such as stress on the fish in the fish pond. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the utility model provides a cleaning mechanism for the central pipe of a fish pond, which can automatically remove impurities such as residual bait, fish feces, and colloids accumulated on the central pipe filter screen, keep the central pipe filter screen unblocked, and ensure the circulating water aquaculture.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] A cleaning mechanism for the central pipe of a fish pond includes a central pipe, a filter screen frame, an automatic cleaning mechanism, a top fixing bracket, a bottom fixing bracket, and a bottom outer cover.

Correspondingly, the bottom fixing bracket 5 also has a lower installation plate 51 with a disc-shaped structure. Two lower installation platforms 52 protrude outward from the left and right sides of the lower installation plate 51. A fixing rod 7 is installed between a set of upper installation platforms 42 and lower installation platforms 52, and the fixing rod 7 connects the top fixing bracket 4 and the bottom fixing bracket 5.

[0019] The central pipe 1 is installed in the middle of the fish pond. A plurality of water outlets are provided on the central pipe for discharging the water body in the fish pond. The central pipe 1 passes through the bottom outer cover 6 and the bottom fixing bracket 5. The filter screen frame 2 is installed between the top fixing bracket 4 and the bottom fixing bracket 5. The filter screen frame 2 is a hollow cylindrical structure and covers the central pipe 1 inside it. There is enough accommodation space between the filter screen frame 2 and the central pipe 1. Long strip-shaped through holes 21 are evenly arranged on the outer wall of the filter screen frame 2. The through holes 21 are used for the water body to flow into the accommodation space and enter the central pipe 1. A filter screen (not shown in the figure) is installed on the outer wall of the filter screen frame 2. The filter screen is used to prevent impurities from entering the central pipe 1. The automatic cleaning mechanism 3 is arranged on the outside of the filter screen frame 2. The automatic cleaning mechanism 3 is used to clean the filter screen regularly. A brush 35 is arranged on the automatic cleaning mechanism 3. The brush 35 contacts the filter screen, and the filter screen is cleaned by the brush 35 to remove organic impurities such as residual bait, fish feces, and colloids on the filter screen.

[0020] The automatic cleaning mechanism 3 includes a motor 31, a large gear set, a small gear set, a rotating bearing 34 and a brush 35. The rotating bearing 34 is rotatably installed between another upper mounting table 42 and the lower mounting table 52. The motor 31 is installed at the upper end of an upper mounting table 42 of the top fixing bracket 4. The driving end of the motor 31 is connected to the rotating bearing 34 through a conversion connector (not shown in the figure). The rotating bearing 34 is driven to rotate by the motor 31. The large gear set includes an upper large gear 321 and a lower large gear 322. The upper large gear 321 is sleeved on the outer wall of the upper end of the filter screen frame 2. The lower large gear 322 is sleeved on the outer wall of the lower end of the filter screen frame 2. The upper large gear 321 and the lower large gear 322 can drive the filter screen frame 2 to rotate. The small gear set includes an upper small gear 331 and a lower small gear 332. The upper small gear 331 is installed at the lower end of the upper mounting table 42 and is located directly below the motor 31. The lower small gear 332 is installed at the upper end of the lower mounting table 52. The rotating bearing 34 passes through the upper small gear 331 and the lower small gear 332 respectively. When the rotating bearing 34 rotates, it can drive the upper small gear 331 and the lower small gear 332 to rotate together. The upper small gear 331 is in gear connection with the upper large gear 321, and the lower small gear 332 is in gear connection with the lower large gear 322. When the upper small gear 331 and the lower small gear 332 rotate, they can drive the upper large gear 321 and the lower large gear 322 to rotate respectively, and the upper large gear 321 and the lower large gear 322 then drive the filter screen frame 2 to rotate.

[0021] The brush 35 is installed on the fixed rod 7 through a plurality of connection structures. The front end of the brush 35 contacts the filter screen on the outer wall of the filter screen frame 2. When the filter screen frame 2 rotates, the brush 35 can sweep off the impurities attached to the filter screen to prevent the filter screen from being blocked. Further, Figure 3As shown in the figure, the connection structure includes two connection blocks 72, a locking post 73 and a spring 74. The two connection blocks 72 are relatively installed on the fixed rod 7. The connection block 72 is in an L-shaped structure. A long strip-shaped locking hole 721 is opened at the front end of the connection block 72. The locking post 73 is arranged on the brush 35. The locking post 73 is a cylindrical column, and its diameter is smaller than that of the locking hole 721. During installation, the locking post 73 is sleeved into the locking hole 721. Since the locking hole 721 is in a long strip-shaped structure, the locking post 73 has a certain movement space in the locking hole 721. The spring 74 is arranged between the brush 35 and the fixed rod 7 and is located between the two connection blocks 72. Under the action of the spring 74, the brush 35 can closely adhere to the surface of the filter screen to ensure the cleaning effect of the brush 35.

[0022] The working principle of the present utility model is as follows:

[0023] The motor 31 is started through a control program, drives the rotary bearing 34 to rotate through a conversion connector. The rotation of the rotary bearing 34 drives the upper pinion 331 and the lower pinion 332 to rotate. Then, the upper pinion 331 and the lower pinion 332 respectively drive the upper large gear 321 and the lower large gear 322 to rotate. Since the upper large gear 321 and the lower large gear 322 are installed on the filter screen frame 2, the rotary bearing 34 can drive the filter screen frame 2 to rotate, and the filter screen 22 on the filter screen frame 2 also rotates accordingly. At the same time, the spring 74 provides elastic force to the brush 35. Under the action of the spring 74, the brush 35 can closely adhere to the surface of the filter screen, so that the brush 35 generates a pressure contact with the filter screen. When the filter screen 22 rotates, the brush 35 plays a role in washing the filter screen. In addition, the motor 31 can be controlled by an external program to start working regularly and stop automatically after working for a certain period of time, thereby effectively saving energy and usage costs.

[0024] In the present utility model, the filter screen frame is set as a rotatable structure. When the filter screen frame rotates, the brush can clean the filter screen on the filter screen frame. The brush can wash off the accumulated residual baits, fish feces and colloids on the filter screen, so that the filter screen is not blocked, ensuring the circulating water aquaculture. Impurities will not enter the central pipe and deposit. Therefore, there is no need to manually remove the central pipe for cleaning, which greatly saves labor and reduces the adverse effects such as stress on fish, and has a good cleaning effect. The present utility model can also be controlled by an external program to start the motor working regularly and stop automatically after working for a certain period of time, realizing an automatic cleaning effect. The present utility model is suitable for large-scale farms.
