Abstract
The utility model discloses a drain grating and escape-preventing device for fish water-flowing culture, and relates to drain grating and escape-preventing devices. The drain grating and escape-preventing device for fish water-flowing culture resolves the problems that fishes escape after an existing drain grating and escape-preventing device is damaged due to too many pollutants and over large water flow pressure. Two triangular frameworks are congruent isosceles triangles in shape, the two triangular frameworks are parallel up and down, orthographic projections of the two triangular frameworks on the ground are coincide, the two triangular frameworks are fixedly assembled into a whole through a plurality of steel bars, the plurality of steel bars are parallel with each other, the distance between every two adjacent steel bars is equal, a drain grating and escape-preventing net is arranged on short edges of the two triangular frameworks and planes where the steel bars connected with the short edges are located, and the screen of the drain grating and escape-preventing net is 1cm*1cm. the drain grating and escape-preventing device for fish water-flowing culture is used for drain grating and escape-preventing in fish water-flowing culture.
Description
Technical field
The utility model relates to a kind of dirty anti-escape device that blocks, and is specifically related to a kind of dirty anti-escape device that blocks for the breed of fish flowing water.
Background technology
Through history in several thousand is arranged, traditional aquaculture model mainly was traditional fish species such as hydrostatic pond culture green grass or young crops, grass, silver carp, flathead to China's fish culture already.In recent years along with Chinese economic development, people's daily life level improves constantly the continuous developing with China's culture fishery, some are as rainbow trout, taimen, the breed of new varieties such as mountain woman trout and Luo Shi Minnow also obtains large-area popularization, the cultural technique that matches with it along with the popularization of new varieties and breeding facility are also in constantly research and development and perfect, the aquaculture model of above-mentioned new varieties mainly is the flowing water pond culture, because above-mentioned fish have one extremely strong enduring the characteristic that current move about, therefore just need one to prevent that fish from runing away and tackle the device of pollutants such as leaf and pasture and water at the water channel of culturing the pond entry.It is existing that anti-to escape to block dirty device mainly be flat shape since pollutant too much and water flow pressure is excessive cause preventing escaping to block dirty device breakage after fish run away, tend to the unnecessary loss that arrives to the fisherman.
The utility model content
The utility model for solve existing anti-escape to block dirty device since pollutant too much and excessive causing of water flow pressure anti-ly escape to block the problem that fish run away after the dirty device breakage, and then provide a kind of dirty anti-escape device that blocks for the breed of fish flowing water.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be:
The dirty anti-escape device that blocks of culturing for fish flowing water of the present utility model comprises two triangular framings, many reinforcing bars and block the dirty anti-net of escaping, two triangular framings are congruent isosceles triangle framework, two triangular framings be arranged in parallel up and down, two orthographic projections of triangular framing towards ground overlap and arrange, two triangular framings install by many reinforcing bars and are one, be arranged in parallel between the many reinforcing bars and adjacent two bar space equate, be equipped with on the plane at the reinforcing bar place that the minor face of two triangular framings is coupled to block and dirty anti-escape net, blocking the dirty anti-mesh of escaping to net is 1cm * 1cm.
The beneficial effects of the utility model are: be equipped with on the plane for the coupled reinforcing bar place of the minor face that blocks two triangular framings of dirty anti-escape device of fish flowing water breed of the present utility model and block the dirty anti-net of escaping, the area of plane at the reinforcing bar place that the minor face of two triangular framings is coupled is greater than the area of plane at coupled reinforcing bar place, the long limit of triangular framing, anti-escape to block dirty device and have only one to block and dirtyly anti-ly escape face and compare with existing, be equivalent to increase the discharge area, reduced and blocked the dirty anti-wire side water flow pressure of escaping to net, anti-to escape to block dirty device unsuitable damaged, greatly reduces the run away generation of event of fish.
Description of drawings
Fig. 1 schematic perspective view that blocks dirty anti-escape device for the breed of fish flowing water of the present utility model (blocking the dirty anti-net view of escaping omits).
Embodiment
Embodiment one: as shown in Figure 1, the dirty anti-escape device that blocks that is used for the breed of fish flowing water of present embodiment comprises two triangular framings 1, many reinforcing bars 2 and block the dirty anti-net of escaping, two triangular framings 1 are congruent isosceles triangle framework, two triangular framings 1 be arranged in parallel up and down, two orthographic projections of triangular framing 1 towards ground overlap and arrange, two triangular framings 1 install by many reinforcing bars 2 and are one, be arranged in parallel between many reinforcing bars 2 and the spacing of adjacent two reinforcing bars 2 equates, be equipped with on the plane at reinforcing bar 2 places that the minor face of two triangular framings 1 is coupled to block and dirty anti-escape net, blocking the dirty anti-mesh of escaping to net is 1cm * 1cm.
During use, block dirty anti-escape device and be installed in going on the water channel of flowing water pond of the present utility model, the plane at the reinforcing bar place that the minor face of two triangular framings is coupled is towards a side in flowing water pond, the plane at the reinforcing bar place that the long limit of triangular framing is coupled is towards a side of crawl, water in the flowing water pond flows into crawl by blocking dirty anti-escape device, block the dirty anti-pollutants such as net interception leaf and pasture and water of escaping, the periodic cleaning pollutant gets final product.
Can the triangular framing 1 above the water surface be installed by the deck, be convenient to change above deck block and dirty anti-escape net, reduce the working strength of workers of removing contamination, cleaning cleaner.The diameter of triangular framing 1 and reinforcing bar 2 is 1.5cm.
Embodiment two: as shown in Figure 1, the spacing H of adjacent two reinforcing bars 2 of present embodiment is 3cm.So design, the spacing of adjacent two reinforcing bars 2 is little, has strengthened the intensity of blocking dirty anti-escape device.Other composition and connected mode are identical with embodiment one.
Embodiment three: as shown in Figure 1, the length L of present embodiment reinforcing bar 2 is 100cm.So design, the length L of reinforcing bar 2 quite arranges with the height of culturing the pond.Other composition and connected mode are identical with embodiment one or two.
Embodiment four: as shown in Figure 1, the length L 1 on present embodiment triangular framing 1 long limit is 200cm, and the length L 2 of two minor faces is 150cm.So design has increased the discharge area greatly.Other composition and connected mode are identical with embodiment three.
