Abstract
The utility model relates to a fish-electrifying apparatus with double purposes of a driving and a blocking effects, which comprises an automatic protecting line of a submarine electrode short circuit, a unidirectional and positive-negative bidirectional pulse converting line and a set of two-row screen-shaped electric grate. The utility model has two functions of electric driving and electric blocking, is especially applied to reservoir fisheries, and has the advantages of good driving and blocking effect, investment and labor saving and obvious economic benefit.
Description
The related electric fishing technical field of the utility model is to the improvement of fish-electrifying device.
General fish-electrifying device, electricity are caught up with and electric blocking is discrete.If electricity consumption is blocked equipment and is caught up with as electricity, because of anhydrous bottom electrode short circuit automatic safety device, when electricity catches up with ship to turn, electrode short circuit repeatedly under water, equipment easily breaks down and can not continuous operation; If electricity consumption catches up with the fishing machine to block as electricity, its power output is less than normal again, and the electric field scope is also too narrow.The pouncing on of China overwhelming majority reservoirs drag for block flood season fish respectively the different times in a year carry out.Thereby the fish-electrifying device availability of function singleness is low.
The purpose of this utility model provides a kind of electricity that has concurrently and catches up with the fish-electrifying apparatus that blocks function two-purpose with electricity, is the important improvement to fish-electrifying device.
The main points of this fish-electrifying apparatus are: electric pole short circuit protection circuit is under water arranged, the conversion line that produces unidirectional and positive and negative bidirectional pulse is arranged, and be furnished with cover double-row type screen shape electricity grid.
The automatic protection circuit of electric pole short circuit under water adopts electrode load resistance (3) under water to seal in the mode of triode bias line.In the bias line, have one by diode (1), adjustable resistance (2) reaches the series circuit of electrode (3) composition under water.This series circuit is in parallel with the series circuit that two diodes (4), (5) are formed again.The automatic protection circuit of this electric pole short circuit under water when electrode is collided short circuit under water, makes main circuit be in off-state; After electrode separates under water, connect main circuit automatically, make machine recover normal operating conditions immediately.So can guarantee the continuous effective ground work when catching up with of this machine as electricity.The conversion line that produces unidirectional and positive and negative bidirectional pulse can make this machine little endure during to 0.5 ohm of electrode load resistance under water, thereby makes the high water body of this functional adaptation electrical conductivity and form big blocking-up face.When catching up with, can export and to make the unidirectional pulse that electricity is caught up with as electricity; When blocking as electricity, export positive and negative bidirectional high-pressure pulse, set up by electric grid and be similar to the electric field that electric main is set up.But utilize this conversion line output similar electric field of setting up, save and safety than direct use electric main.Under identical supply voltage, the electric-field intensity that bidirectional pulse is set up is the twice of unidirectional pulse, and short to the residence time of fish effect.The such conversion line series connection of multi-section is used and can be improved output voltage.Depend on following special circuit, this conversion line is achieved its function: circuit and accumulator (6) that controllable silicon (7) and inductance (8) series connection constitute compose in parallel.Accumulator (6) and inductance (8) can be connected with electrode (3) under water by change-over switch (9) respectively, also can be connected with negative pole (10), adopt double-row type screen shape electricity grid when blocking as electricity, and these electricity grid are made of the parallel electric grid of two rows.The electric grid of one row are equidistant alternate positive electrode (11) and the negative electrodes (12) of row, and another arranges electric grid is the equidistant positive electrodes arranged of row, promptly aforementioned negative pole (10).The stagger phase place of half interval of two row electrodes, promptly arrange on the perpendicular bisector of adjacent two electrode connecting lines in the electric grid at another the position of electrode in the electric grid of a row.In the two row electrodes, the electric potential gradient of electrode is: positive electrode (11) current potential of the row that both positive and negative polarity is alternate is the highest, and negative electrode (12) current potential is minimum; Another row only contain the positive electrode (10) in the electric grid of positive electrode, and its current potential is between the above-mentioned positive and negative electrode that contains positive and negative electrode electricity grid.Like this, can strengthen electrode gap, the electric field scope that electric grid form also enlarges, and the fish near electric grid can both be subjected to bigger multiple electric field effects from different directions, blocks the fish effect thereby improved.
The advantage of the utility model fish-electrifying apparatus is that electricity is caught up with electricity and blocked dual-purpose, save electric energy, save artificial, safety, stable, efficient is high.Has remarkable economic efficiency through medium and small reservoir field trial proof.
