Embodiment
Below in conjunction with specific embodiment, the present invention is further described.
According to fish, high light is had the characteristic of escape, the present invention has designed a kind of laser assisted fish-catching apparatus.
The first embodiment:
As shown in Figure 1 and Figure 2, a kind of pond culture laser assisted is fished for device, comprises strip PVC float 1, and described 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, described pond.On described float 1, have at least one cable 2, along described cable 2, be provided with laser transmitter group 3, described laser transmitter group 3 is connected with generating laser drive system by cable 2, the laser beam of described laser transmitter group 3 transmittings forms netted laser grating face, and intersect the bottom surface in described laser grating face and described pond.Described cable 2 one end extend to 4 banks, pond, are connected with generating laser drive system, and generating laser drive system is by the accumulator direct current stabilizer of alternating current (or connect) power supply, and both are positioned in a go-cart 6.Described generating laser drive system comprises: pulsed drive system, described pulsed drive system comprises pulse-width modulator, frequency regulator, described pulse-width modulator, frequency regulator are connected with impulse generator respectively, described impulse generator is connected with pulse amplifier, described pulse amplifier is connected with pulse power amplifier, and described pulse power amplifier is connected with described laser transmitter group 3; DC drive system, described DC drive system comprises DC generator, and described DC generator is connected with dc amplifier, and described dc amplifier is connected with linear power amplifier, and described linear power amplifier is connected with described laser transmitter group 3.Also comprise signal selector, described signal selector is connected with DC generator with impulse generator respectively, the pulse laser of some fish is more responsive, the continuous laser of some fish is more responsive, while using pulse and continuous laser, effect is best simultaneously, but the most energy-conservation while only using pulse laser, therefore strobe pulse and/or continuous Laser output flexibly according to actual needs.Described laser grating face is vertical with the bottom surface in pond 4.As shown in Figure 2, the RC generating laser of laser transmitter group 3 is Emission Lasers straight down, and there is certain inclination angle at the laser beam Jun Xiang center of other generating lasers on both sides, that is, all intersect with center laser beam straight down.
While preparing fishing, according to adult fish size selected element type or linear laser transmitter quantification in on-the-spot culturing pool water surface specification and pond, generating laser is equidistant to be arranged on a PVC float, length is slightly longer than water surface width, and laser beam is downward, and a cable is installed on float, auxiliary output of fishing for device is connected with the cable on float, generating laser is connected with cable, and laser assisted fishes for device and power supply is placed in go-cart, float is placed in to the one side in pond.During fishing operation, float and dolly advancing to another side at the uniform velocity under artificial effect, under the effect of laser grating, in pond, fish is blocked the another side to pond, lasting propelling along with float, fish density between float and pond another side in 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, fish density advances float when low, when fish density is high, fish with a net, operation is until stop the auxiliary device work of fishing for after fishing for end repeatedly, in pond, residue adult fish recovers conventional animation.
The second embodiment:
Laser beam branch in the first embodiment is uneven, relatively concentrates on the middle and upper part of grating face, for the fish that is positioned at middle and upper part, pond, has the effect of driveing preferably, but less for the effect of driveing of the fish near two sides and pond bottom.
So as shown in Figure 3, the difference of the second embodiment and the first embodiment is, the Laser emission direction of generating laser vertically parallel downwards, form uniform grating face.
The 3rd embodiment:
Gap between first and second embodiment grating is larger, sometimes can not stop individual petite fish completely, therefore on the basis of above-mentioned laser assisted fish-catching apparatus, improves as follows:
As Figure 1 and Figure 4, the laser parallel of laser transmitter group 3 transmitting and straight down, simultaneously by increasing the generating laser of one group of horizontal direction, a cable vertically downward and the fixedly pillar of generating laser are installed in the middle of former float, cable and generating laser are fixed on pillar, this cable is the branch cable 8 of former cable 2, two groups of generating lasers are arranged on the both sides of pillar, direction is respectively towards two banks, with bank lateral vertical, what when on float and pillar, generating laser is worked like this, send is the grating of square net.
