Embodiment
Below in conjunction with specific embodiment the present invention is further specified.
There are the characteristic of escape, the present invention to design the auxiliary fish-catching apparatus of a kind of laser according to fish to high light.
First embodiment:
Like Fig. 1, shown in Figure 2, a kind of pond culture laser is auxiliary fishes for device, comprises strip PVC float 1, and said float 1 floats on 4 waters surface of pond, and 4 two sides, pond are extended at float 1 two ends, and vertical with bank, said pond.Have at least one cable 2 on the said float 1; Be provided with laser transmitter group 3 along said cable 2; Said laser transmitter group 3 is connected with the generating laser drive system through cable 2; Said laser transmitter group 3 emitted laser rays form netted laser grating face, and intersect the bottom surface in said laser grating face and said pond.Said cable 2 one ends extend to 4 banks, pond, are connected with the generating laser drive system, and the generating laser drive system is by the accumulator direct current stabilizer of alternating current (or connect) power supply, and both are positioned in the go-cart 6.Said generating laser drive system comprises: the pulsed drive system; Said pulsed drive system comprises pulse-width modulator, frequency regulator; Said pulse-width modulator, frequency regulator are connected with impulse generator respectively; Said impulse generator is connected with pulse amplifier, and said pulse amplifier is connected with pulse power amplifier, and said pulse power amplifier is connected with said laser transmitter group 3; Dc drive system, said dc drive system comprises dc generator, and said dc generator is connected with dc amplifier, and said dc amplifier is connected with linear power amplifier, and said linear power amplifier is connected with said laser transmitter group 3.Also comprise signal selector; Said signal selector is connected with dc generator with impulse generator respectively; The pulse laser of some fish is responsive, and the continuous laser of some fish is responsive, and effect is best when using pulse and continuous laser simultaneously; But the most energy-conservation when only using pulse laser, therefore strobe pulse and/or continuous laser output flexibly according to actual needs.Said laser grating face is vertical with the bottom surface in pond 4.As shown in Figure 2, laser transmitter group 3 RC generating lasers are launched laser straight down, and the laser beam of other generating lasers on both sides all has certain inclination angle to the center, that is, all intersect with centermost laser beam straight down.
When preparing fishing, according to adult fish size selected element type or linear laser transmitter and quantification in on-the-spot culturing pool face specification and the pond, generating laser is equidistant to be installed on the PVC float; Length slightly is longer than water surface width, and laser beam is downward, and a cable is installed on the float; Auxiliary fish for the output of device and be connected with cable on the float; Generating laser is connected with cable, and laser is auxiliary fishes for device and power supply places in the go-cart, float is placed the one side in pond.During fishing operation, float and dolly advancing to another side at the uniform velocity under the manual work effect is under the effect of laser grating; Fish is blocked the another side to the pond in the pond, and along with the lasting propelling of float, the fish density between float and the pond another side in the waters constantly increases; When float is advanced to suitable fish density; Keep the auxiliary device operation of fishing with a net in running order time of fishing for, advance float when fish density is low, fish with a net when fish density is high; Repeatable operation stops to assist after fishing for end fishes for device work, and the residue adult fish recovers conventional animation in the pond.
Second embodiment:
Laser beam branch among first embodiment is uneven, relatively concentrates on the middle and upper part of grating face, for the fish that is positioned at the middle and upper part, pond the effect of driveing is preferably arranged, but less for the effect of driveing near the fish of two sides and pond bottom.
So as shown in Figure 3, the difference of second embodiment and first embodiment is that the Laser emission direction of generating laser is vertically parallel downwards, forms uniform grating face.
The 3rd embodiment:
Gap between first and second embodiment grating is bigger, can not stop individual petite fish sometimes fully, therefore on the basis of the auxiliary fish-catching apparatus of above-mentioned laser, improves as follows:
Like Fig. 1, shown in Figure 4; Laser transmitter group 3 emitted laser are parallel and straight down, simultaneously through increasing the generating laser of one group of horizontal direction, cable and a fixedly pillar of generating laser vertically downward are installed in the middle of former float promptly; Cable and generating laser are fixed on the pillar; This cable is the both sides that 8, two groups of generating lasers of branch cable of former cable 2 are installed in pillar, and direction is respectively towards two banks; With the bank lateral vertical, what send when generating laser is worked on float and the pillar like this is the grating of square net.
