Abstract
The invention provides a device for automatically cleaning a net cage underwater and relates to a device for controlling and removing fouling organisms on a buoyant raft cultivation cage on the sea. A bamboo rod penetrates through round holes in the centers of all net cage partition plates in sequence, the net cage is drawn straightly into the longest supporting state to be identical with a net in diameter basically, and all the net cage partition plates are located on the same axis. The net scraper is installed on the net cage in a sleeving mode, locating rings are installed on the upper and lower partition plates of the net cage so that the upper portion and the lower portion of the net scraper can not break away from the net cage, a sand bag is installed under the net cage so that the time for the net cage perpendicular to the sea surface can be prolonged, the net cage is connected with a raft body through a hanging rope, and the upper portion of the raft body and a floating ball are connected through a buoyancy rope to form the device. According to the device, the net scraper can float to the top of the net cage when no tide exists, when the tide is increased to a certain degree, the net scraper can move to the bottom of the net cage, in the process, waves can make the net scraper do high-frequency motion on the local part of the net cage, and the motion has impact force to make it difficult for the fouling organisms to adhere to and exist on the net cage.
Description
Technical field
The present invention relates to preventing and kill off of fouling organism on agriculture marine buoyant raft aquiculture mesh cage, is for power is to a kind of device of cylinder mould underwater automatic cleaning with trend and wave.
Background technology
The patent such as " a kind of method to cylinder mould underwater automatic cleaning ", " a kind of device to cylinder mould underwater automatic cleaning " is authorized at present, and concrete technical scheme is all be sleeved on by a kind of circular ring buoy net scraper (scraping hereinafter referred to as net) on cylinder mould and make it all can not depart from cylinder mould up and down.Its operation principle is: when not having trend, and cylinder mould is perpendicular to sea, and the top floating to cylinder mould by natural buoyancy scraped by net; Can swing to direction of tide along with trend constantly increases cylinder mould, when the angle swung reaches certain level degree, the bottom moving to cylinder mould under the pulling of trend scraped by net.Facts have proved and to scrape in the process that relative cylinder mould moves up and down at net, the configuration of cylinder mould be there are certain requirements.The cylinder mould of current use, be connected by etting between dividing plate with dividing plate, this soft connection causes the etting diameter between two dividing plates inconsistent, local diameter the closer to dividing plate is larger, can diminish at the etting diameter in two dividing plate centre positions, in addition owing between net cage separator with dividing plate being soft connection, cylinder mould under water time, dividing plate entirety is not often on same axial line, above-mentioned two kinds of reasons can make net swipe in a certain position of cylinder mould, are difficult to realize predetermined net and scrape moving up and down of relative cylinder mould.
Summary of the invention
Make net swipe in a certain position of cylinder mould to overcome existing cylinder mould, be difficult to realize the technology drawback moved up and down that relative cylinder mould scraped by predetermined net, the invention provides a kind of new technical side by: insert a bamboo pole in the middle of the net cage separator and etting diameter can not only be made basically identical, and can make each net cage separator on same axial line.
The technical scheme that the technical problem that the present invention solves adopts is: net cage separator is transformed into central authorities with circular hole, circular has multiple length that is uniformly distributed equal and perpendicular to the gap of circular hole, bamboo pole diameter being greater than circular hole in the middle of net cage separator passes from the circular hole of each net cage separator central authorities successively, and props up state by stretching for cylinder mould to the longest.The automatic banding bamboo pole of elasticity that circular hole in the middle of each net cage separator can utilize plastics itself to have, makes the etting diameter on cylinder mould basically identical, and can make net cage separator all on same axial line.
The invention has the beneficial effects as follows, reduce net and scrape the probability violating card on cylinder mould, the operating efficiency to cylinder mould underwater automatic cleaning scraped by raising net.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and case study on implementation, the present invention will be further described.
Fig. 1-1 in Fig. 1 is the overall structure figure of cylinder mould, and Fig. 1-2 is the partial enlarged drawing of Fig. 1-1, and in Fig. 1,6. is cylinder moulds, is 9. bamboo poles, is 10. net cage separators.
Fig. 2 is the net cage separator of middle with hole.
Fig. 3 is the fundamental diagram of a kind of device of the present invention.Fig. 3-1 in Fig. 3 is when not having trend, and net is scraped and the relative position figure residing for cylinder mould, Fig. 3 in Fig. 3-2 and Fig. 3-3 be trend larger time, net is scraped and the relative position figure residing for cylinder mould.In Fig. 3,1. is buoyant spheres, is 2. buoyancy ropes, is 3. raft bodies, is 4. lifting ropes, is 5. circular ring buoy net scrapers, is 6. cylinder moulds, is 7. sandbags, is 8. locating rings, α. represent cylinder mould pivot angle, the position on sea when A. represents full sea, B. represents the position on half time of tide sea.
Embodiment
By Fig. 2 by disposable for net cage separator compression or injection mo(u)lding, make net cage separator central authorities have circular hole, circular has multiple length that is uniformly distributed equal and perpendicular to the gap of circular hole, then etting and dividing plate to be stitched together by traditional handicraft and to make cylinder mould.The bamboo pole in use diameter being greater than circular hole in the middle of cylinder mould passes from the circular hole of each net cage separator central authorities successively, and props up state by stretching for cylinder mould to the longest.Being scraped by net is sleeved on cylinder mould, and lower clapboard is installed locating ring on cylinder mould and net is scraped all can not depart from cylinder mould up and down, a sandbag is installed below cylinder mould and can extends the time of cylinder mould perpendicular to sea, be connected with raft body by lifting rope by cylinder mould, raft with it face connects to form a kind of device by buoyancy rope and buoyant spheres.
Marine tidal-current energy changes the size of direction and flow velocity twice daily with the change of tide, causes cylinder mould every day correspondingly to change pivot angle size at different directions.This device tidal current speed when full sea levels off to zero, and cylinder mould is perpendicular to sea, and the top (Fig. 3-1 as in Fig. 3) floating to cylinder mould by self buoyancy scraped by net; Along with the continuous increase of trend, cylinder mould can swing certain angle-α pivot angle to direction of tide, and when α pivot angle increases to a certain degree, the bottom (Fig. 3-2 as in Fig. 3) moving to cylinder mould under the impact of trend scraped by net.Then along with trend slows down, cylinder mould in the opposite direction repeats above-mentioned action (Fig. 3-3 as in Fig. 3) perpendicular to sea again.Change every day that net is scraped according to trend realizes two large strokes up and down at cylinder mould.
In above process, when wave is formed on the sea on cylinder mould top, cylinder mould rises to certain height with buoyant spheres by wave, in this rapid movement, owing to being subject to seawater drag effects, the movement velocity that net is scraped always is less than cylinder mould, and both will produce relative motion.This is that the high frequency motion of the local of power has impulsive force with wave, makes fouling organism cannot adhere to existence on cylinder mould.
