Abstract

The invention discloses a method for automatically cleaning a mesh cage underwater in a swinging plate manner. A raft body on the upper part of the mesh cage is connected with a rectangular swinging plate through two upper swinging ropes; the lower surface of the swinging plate is connected with a group of scraping rings through two lower swinging ropes; the lowest scraping ring is matched with a hanging object to form a device. A group of scraping rings in the device is sleeved on the mesh cage, and both the upper part and the lower part of the group of scraping rings cannot be separated from the mesh cage. When a tide does not exist, the swinging plate of the device is perpendicular to the sea surface, and the scraping rings move to the bottom part of the mesh cage under the gravity effect of the hanging object; when the tide is increased to a certain degree, the swinging plate can swing by a certain angle toward the tide under the impact of the tide, and the scraping rings are lifted to move to the top part of the mesh cage through the lower swinging ropes. Underwater automatic scraping and cleaning of a mariculture mesh cage can be realized by the vertical movement of the scraping rings relative to the mesh cage. The method has the advantages that mechanical damage of cultivated shellfish caused by excessive swinging of the mesh cage is avoided effectively, and the survival rate and the yield of the cultivated shellfish are improved.

Description

A kind ofly put the board-like method to cylinder mould underwater automatic cleaning

Technical field

The present invention relates to preventing and kill off of fouling organism on seawater suspended longline farming cylinder mould, is a kind of method to cylinder mould underwater automatic cleaning.

Background technology

The multinomial patented technology such as " a kind of method and apparatus to cylinder mould underwater automatic cleaning " and product are applied aborning at present, and concrete grammar is all a kind of circular ring buoy net scraper (scraping hereinafter referred to as net) is sleeved on cylinder mould and makes it all can not depart from cylinder mould up and down.Basic principle is: when there is no trend, cylinder mould is perpendicular to sea, and net is scraped the top that floats to cylinder mould by self buoyancy; Along with trend constantly increases cylinder mould, can swing to direction of tide, when the angle swinging reaches " certain level degree ", net is scraped the bottom that moves to cylinder mould under the pulling of trend.Therefore trend is drawn to cylinder mould prerequisite and the important indicator that " certain level degree " is this technology.But in Liaoning, extensively the smooth shellfish of shrimp of cultivation is because itself does not have byssus for Hebei, northern China coastal area, Shandong, cylinder mould significantly swings and cause the mutual collision friction shell of shellfish body very easily to damage every day, causes shellfish disabled, undergrowth and death.

Summary of the invention

In order to overcome cylinder mould, significantly swing every day and to cause the mutual collision friction shell of shellfish body very easily to damage, cause shellfish disabled, undergrowth and dead problem.The invention provides a kind of new technical scheme: a kind of device is installed on existing cylinder mould, under the very little state of amplitude that this device can not swing or swing at cylinder mould, is realized the underwater automatic cleaning to cylinder mould.

Technical scheme provided by the invention is: the raft body (3) on cylinder mould top above connects a square pendulum plate of block length (5) by two upper swing ropes (4), pendulum plate (5) connects one group of scraping ring below by two lower swing ropes (6), scraping ring (7) has four equally distributed circular holes above, and each circular hole is joined together to form one group of scraping ring by connection cord (8) by scraping ring (7) is equidistant.Nethermost scraping ring is furnished with hanging thing (9) and forms a kind of device.One group of scraping ring in this device is sleeved on cylinder mould, and makes it all can not depart from cylinder mould up and down.This device is put plate (5) perpendicular to sea (A) when there is no trend, move in scraping ring (7) bottom to cylinder mould under the Action of Gravity Field of hanging thing (9), when trend increases to a certain degree, pendulum plate (5) can swing certain angle to direction of tide and move to cylinder mould top by lower swing rope (6) lifting scraping ring (7) under the impact of trend, realize scraping ring (7) moving up and down of cylinder mould (12) relatively, reach the cylinder mould object that automatic scraping is washed under water.

The invention has the beneficial effects as follows: effectively avoid cylinder mould excessively to swing the mechanical damage that cultivated shellfish is caused, improve survival rate and the output of cultivated shellfish.

Embodiment

Buoyant spheres (1) on sea in Fig. 1-1 (A) connects raft body (3) below by buoyancy rope (2), raft body (3) on cylinder mould top above connects a square pendulum plate of block length (5) by two upper swing ropes (4), pendulum plate (5) connects one group of scraping ring below by two lower swing ropes (6), scraping ring (7) has four each circular holes of equally distributed circular hole to be joined together to form one group of scraping ring by connection cord (8) by scraping ring (7) is equidistant above, and nethermost scraping ring is furnished with hanging thing (9) and forms a kind of " device ".One group of scraping ring that will be somebody's turn to do in " device " is sleeved on cylinder mould, steering-wheel-shaped positioning ring (11) is installed on lower clapboard on cylinder mould and is made scraping ring (7) all can not depart from cylinder mould up and down.Sandbag is installed below cylinder mould (12) to be prevented from too swinging under the impact of cylinder mould in trend.

The maximum perpendicular travel settings that distance between each scraping ring can produce according to pendulum plate, upper swing rope and lower swing rope, is slightly less than range in principle.The quantity of scraping ring (7) should be set according to the length of cylinder mould, while there is no trend in principle, nethermost scraping ring can not fall back to the bottom (seeing Fig. 2-1) of cylinder mould, and when trend increases to a certain degree, uppermost scraping ring can move to the top (seeing Fig. 2-2) of cylinder mould.

The minimum diameter of scraping ring is greater than net cage separator diameter 5-10 millimeter, prevents that scraping ring is stuck on net cage separator when cylinder mould swings to a certain degree, can suitably increase if desired the amplitude of the weight limits cylinder mould swing of sandbag (13).

The area of pendulum plate (5), length is set according to trend size and needed vertical stroke size, the large cultivation marine site of trend pendulum plate (5) on the contrary area can be suitably less more greatly, vertical stroke is required can suitably increase greatly to the length of pendulum plate (5) and lower swing rope (6), but the angle that will suitably control between lower swing rope (6) and lifting rope (10) can not be too large, 30 degree are following is advisable, otherwise the excessive scraping ring (7) that easily causes of transverse component that lower swing rope (6) produces scraping ring (7) is stuck on cylinder mould, affects scraping ring (7) to the motion at cylinder mould top.
