Description

Contamination and anti-escape device for fish running water aquaculture

technical field

The utility model relates to a dirt-blocking and escape-preventing device, in particular to a dirt-blocking and escape-preventing device for fish farming in running water.

Background technique

my country's fish farming industry has a history of thousands of years. The traditional farming model is mainly to breed traditional fish species such as green carp, grass carp, silver carp and bighead carp in still water ponds. In recent years, with the development of my country's economy, the continuous improvement of people's daily living standards and the continuous development of my country's aquaculture industry, some new varieties such as rainbow trout, panacea, mountain female trout and Rock's carp have also been widely promoted. With the promotion of new species and the matching breeding technology and breeding facilities are constantly being developed and improved, the breeding mode of the above-mentioned new species is mainly running water pond culture. Therefore, the water channel entering the aquaculture pond needs a device to prevent fish from escaping and intercept pollutants such as leaves and aquatic plants. Existing anti-escape trash-blocking devices are mainly planar. Due to excessive pollutants and excessive water flow pressure, fish escape after the anti-escape trash-blocking device is damaged, often causing unnecessary losses to fishermen.

Utility model content

The utility model aims to solve the problem of fish escaping after the anti-escape trash device is damaged due to excessive pollutants and excessive water flow pressure in the existing anti-escape trash device, and further provides a trash trap for fish flowing water aquaculture. Anti-escape device.

The technical scheme that the utility model takes for solving the problems of the technologies described above is:

The pollution-stopping and anti-escape device for fish running water culture of the utility model includes two triangular frames, multiple steel bars and pollution-stopping and anti-escape nets. The two triangular frames are all isosceles triangle frames, and the two triangle frames are parallel up and down. Setting, the orthographic projections of two triangular frames facing the ground are overlapped and set. The two triangular frames are fixed as a whole by multiple steel bars. The multiple steel bars are arranged parallel to each other and the distance between two adjacent steel bars is equal. A dirt-blocking and escape-proof net is installed on the plane where the steel bars connected to the short side are located, and the mesh of the pollution-stopping and escape-proof net is 1cm×1cm.

The beneficial effects of the utility model are: the dirt-blocking and escape-preventing device for fish flowing water cultivation of the utility model is provided with a dirt-blocking and escape-proof net on the plane where the short sides of the two triangular frames are connected to the steel bars, and the two triangles The plane area where the short sides of the frame are connected to the steel bars is greater than the plane area where the long sides of the triangular frame are connected to the steel bars. The water area reduces the water flow pressure on the net surface of the anti-escape anti-fouling net, and the anti-escape and anti-escape device should not be damaged, which greatly reduces the occurrence of fish escape incidents.

Description of drawings

Fig. 1 is a three-dimensional schematic diagram of the dirt-blocking and escape-preventing device for fish flowing water culture of the present utility model (the view of the dirt-blocking and escape-proof net is omitted).

Detailed ways

Specific embodiment one: as shown in Figure 1, the pollution-stopping and escape-preventing device used for fish flowing water culture in this embodiment includes two triangular frames 1, a plurality of steel bars 2 and pollution-stopping and escape-proof nets, two triangular frames 1 It is a full isosceles triangular frame, two triangular frames 1 are arranged parallel up and down, and the orthographic projections of the two triangular frames 1 facing the ground are overlapped and set, and the two triangular frames 1 are fixed as a whole through multiple steel bars 2, and the connection between the multiple steel bars 2 They are arranged parallel to each other and the distance between two adjacent steel bars 2 is equal. The short sides of the two triangular frames 1 are installed on the plane where the steel bars 2 connected to each other are located. ×1cm.

When in use, the dirt blocking and anti-escape device of the present utility model is installed on the water inlet channel of the running water pond, the plane where the short sides of the two triangular frames are connected to the steel bars is facing the side of the running water pond, and the long side of the triangular frame is connected to it. The plane where the steel bars are located is facing one side of the fish pond, and the water in the running water pond flows into the fish pond through the anti-escape device. The anti-escape net intercepts pollutants such as leaves and aquatic plants, and the pollutants can be cleaned regularly.

A deck can be installed on the triangular frame 1 above the water surface, which is convenient for replacing the pollution-stopping and escape-proof net on the deck, reduces the labor intensity of the cleaning workers, and cleans up more cleanly. The diameters of the triangular frame 1 and the steel bar 2 are both 1.5cm.

Embodiment 2: As shown in FIG. 1 , the distance H between two adjacent steel bars 2 in this embodiment is 3 cm. With such a design, the distance between two adjacent steel bars 2 is small, which enhances the strength of the pollution-blocking and escape-preventing device. Other compositions and connection methods are the same as those in Embodiment 1.

Embodiment 3: As shown in FIG. 1 , the length L of the steel bar 2 in this embodiment is 100 cm. Such design, the length L of reinforcing bar 2 is quite set with the height of breeding pond. Other compositions and connection methods are the same as those in Embodiment 1 or 2.

Embodiment 4: As shown in FIG. 1 , the length L1 of the long side of the triangular frame 1 in this embodiment is 200 cm, and the length L2 of the two short sides is 150 cm. Such a design greatly increases the water passing area. Other compositions and connection methods are the same as those in the third embodiment.
