Embodiment
A lot of details have been set forth in the following description so that fully understand the utility model.But the utility model can be implemented to be much different from alternate manner described here, those skilled in the art can do similar popularization without prejudice to the utility model intension in the situation that, so the utility model is not subject to the restriction of following public specific embodiment.
Below, by reference to the accompanying drawings specific embodiment of the utility model is described.Refer to shown in Fig. 1 to Fig. 3, the utility model provides a kind of cellular prelarva to evade the device of harmful animal, the device that described cellular prelarva evades harmful animal is comprised of inner honeycomb structure 1 and outside mesh bag structure 2, outside mesh bag structure 2 is wrapped in inner honeycomb structure 1 outside, thereby forms the space that prelarva evades harmful animal.
Particularly, inner honeycomb structure 1 comprises dead lever 11, net button 12, packaged type clip 13 and cellularly evades case 14, and outside mesh bag structure 2 comprises landing net 21 and stay cord 22.
Shown in Fig. 1 and Fig. 3, wherein one end of dead lever 11 connects the cellular case 14 of evading, the other end is fixed on below artificial fish shelter 3 by two packaged type clips 13 on bar, and packaged type clip 13 can move up and down according to actual needs on dead lever 11.
On dead lever 11, be also provided with net button 12, described net is buckled 12 and is positioned at packaged type clip below, and described net is buckled 12 and is positioned at apart from dead lever 11 and cellular position of evading case 14 junction 5cm, also can be the arbitrary numerical value between 2cm to 10cm, the factors such as the length of choosing according to actual water environment and dead lever 11 determine.
Described net is buckled 12 and is connected with landing net 21 is dismountable.Particularly, landing net 21 is placed on cellular evading outside case 14, and one end of landing net 21 has openend, and the other end is blind end, openend is provided with stay cord 22, thereby the stay cord 22 of landing net 21 by being positioned at opening part buckle 12 places at net and formed slip-knots and carry out tightening up of landing net 21 and fix.
According to the environment in concrete waters, the length of dead lever 11 and diameter can design accordingly, for example the length of dead lever 11 can be the arbitrary value between 15cm to 40cm, its diameter can be the arbitrary value between 3cm to 10cm, the length of choosing dead lever 11 in the present embodiment is 25cm, diameter is 5cm, by polystyrene (High Impact Polystyrene, HIPS) material shock-resistant, high rigidity, is made.
Describedly cellularly evade the height of case 14 and the size of width also can design according to actual environment, to form the different shape of evading case and size, the height of for example evading case can be the arbitrary numerical value between 30cm to 70cm, and the width of evading case can be the arbitrary numerical value between 10cm to 30cm.In the present embodiment, the height of evading case 14 is 50cm, and width is 20cm.
Cellular case 14 inside of evading consist of honeycomb spleen formula structure 15, honeycomb spleen formula structure comprises the polygon cylinder of a plurality of hollows, for example octagonal cylinder or quadrangle cylinder, and at least one end of cylinder is provided with opening, also can be that two ends all arrange opening, conveniently prelarva be put into and evades case.Preferably, the honeycomb spleen formula structure in the present embodiment 15 is the equilateral hexagon cylinder that two ends all arrange the hollow of opening.The length of side of described honeycomb spleen formula structure 15 decides according to the actual size of evading case of choosing, for example, be that the length of side is the arbitrary numerical value between 3cm to 8cm, and in the present embodiment, its length of side is 6cm.Described cellular material selection of evading case 14 is shock-resistant, the polystyrene (High Impact Polystyrene, HIPS) of high rigidity, to reach the effect of better evading harmful animal.
Described landing net 21 covers in cellular case 14 outsides of evading, and forms in the lump a space of evading harmful animal with the cellular case 14 of evading.By inner diameter of mesh, to be 1mm(arrange according to the height of minimum predation same period fish silverfish prelarva described landing net 21) etting 23 make, the etting 23 in the present embodiment adopts monolayer polyethylene ettings.Because described landing net is to be wrapped in the outside of evading case 14, its size should according to the size of evading case correspondingly design a little more greatly, for example the bag of landing net is long can be the arbitrary numerical value between 35cm to 75cm, and landing net width can be the arbitrary numerical value between 15cm to 35cm.In the present embodiment, the bag of landing net 21 is long is 55cm, and width is 20cm, is wrapped in cellular evading outside case 14, and landing net 21 ends are made the net of slip-knot on dead lever 11 by stay cord 22 and buckled 12 places and close up, and stay cord 22 is polyethylene rope.
The using method of the cellular prelarva in actual mechanical process being evaded to the device of harmful animal below describes, and has two states: duty and off working state during the operation of device of the present utility model.As shown in Figure 4, the concrete using method of device of the present utility model is as described below:
A) prelarva is put into the cellular case of evading when the larvae growth phase starts:
Particularly, prelarva is put into the hollow space of hexagon cylinder by the opening of the hexagon cylinder of honeycomb spleen formula structure 15.
B) landing net is wrapped in to the cellular case outside of evading, forms the space that prelarva evades harmful animal, and by described device vertical hanging under artificial fish shelter:
Particularly, the device vertical hanging of cellular prelarva of the present utility model being evaded to harmful animal by dead lever 11 and the packaged type clip 13 on it is in artificial fish shelter 3 times; Landing net 21 is wrapped in to cellular case 14 outsides of evading, and the openend of landing net 21 is buckled 12 places by stay cord 22 at net and is made slip-knot, landing net 21 is also fixed on dead lever 11, and forms in the lump prelarva the space of effectively evading harmful animal is provided with the cellular case 14 of evading.
C) after the larvae growth phase finishes, take off landing net and rotate the cellular case of evading, the cellular prelarva evading in case is left:
Particularly, untie stay cord 22 to take off landing net 21 from cellular case 14 outsides of evading, and rotate the cellular case 14 of evading, the prelarva that possesses certain swimming and escape harmful animal ability in case can freely be left.Usually, after the larvae growth phase (alevin stage) finishes, enter young stage, prelarva grows up to juvenile fish.
Using method is also further included in and uses later treatment step, as described below:
D) take off the cellular case 14 of evading, by its cleaning and dry, wait until next time and use:
Particularly, untie packaged type clip 13 to take off the cellular case 14 of evading from Artificial Fish reef 3, by its cleaning and dry, wait until next time and use.
Steps A wherein) and step B) be duty, and step C) and D) be off working state.
Above-described embodiment is for illustrative principle of the present utility model and effect thereof, but the utility model is not limited to above-mentioned embodiment.Those skilled in the art all can, under spirit of the present utility model and category, in claim protection domain, modify to above-described embodiment.Therefore protection domain of the present utility model, should cover as claims of the present utility model.
