Technical Field

The invention belongs to laver cultivation, and relates to a device for laver cultivation, in particular to a device for realizing the overturning of a cultivation net by operating a floating ball so that laver can be dried out and photosynthesis is carried out.

Background

The laver is used as a commercial crop, is delicious, is rich in protein and various elements required by human bodies, and is favored by consumers. In recent years, a large number of mudflats are continuously reduced due to engineering construction, and grid culture in shallow sea areas is increasingly favored by people.

In laver cultivation, laver seedlings need to be continuously soaked in seawater and dried on the sea surface to be subjected to solarization, so that large-scale laver grid cultivation becomes very hard and troublesome, and particularly, the grids are pulled back to the land to be solarized, so that the labor intensity of workers is high, the required time is long, and the efficiency is very low.

With the economic development and the technical progress, people try to adopt a power mechanism to drive an adjusting rod through a pull rope, and the adjusting rod drives a floating ball to rotate so as to control the grid to sink and float.

Two relevant documents are presented below to reveal the state of the art.

The invention of Chinese patent application 200710300232.9 discloses a laver cultivation frame, which adopts an inserted link 2 to draw a buoy 4 and a cable 3 through a lifting rope 5, so that a curtain 6 can be submerged into the sea level, and the lifting rope 5 can be manually adjusted to lift the curtain 6 to expose the sea level, so that laver can be cultivated in the curtain 6.

The Chinese patent application 201710937933.7 discloses a laver culture device and a laver culture method based on the device, wherein a driving device 7 pulls an adjusting rope 6 and drives an adjusting rod 5 to rotate together with a float 1, so that a culture net 3 floats out of or is immersed in seawater, and the sinking and floating of the culture net are automatically controlled.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide a laver culture device which is very simple in structure and can turn over a culture net to enable the culture net to sink or float on the sea level.

The laver culturing device of the invention is realized by the following scheme:

a laver culturing device is characterized in that floating balls and cross rods are fixed to form floating ball carrying arms, a plurality of floating ball carrying arms are transversely installed on a culturing net along the length direction, the floating ball carrying arms at the front end and the rear end of the culturing net are respectively a front floating ball carrying arm and a rear floating ball carrying arm, a pair of cables is tied to the left side and the right side of each of the front floating ball carrying arm and the rear floating ball carrying arm respectively, a first cable and a second cable are contained in each pair of cables, and free ends of the first cable and the second cable in each pair of cables are tied together and connected with a third cable.

In this way, the device can be fixed to two posts in the shallow sea area by the free ends of the two third mooring ropes, and the aquaculture net can be easily turned over manually. If the cultivation net is positioned below and the floating ball is positioned above, the laver seedling can be soaked by seawater; if the cultivation net is positioned on the upper surface and the floating ball bearing is positioned on the lower surface, the laver seedling can be exposed to the sun. If the aquaculture net needs to be turned, people can hook the far end of the front floating arm or the rear floating arm cross rod through a pull rod to lift the aquaculture net, and two third mooring ropes are used as a device rotating central shaft to turn the whole aquaculture net.

Preferably, in the laver culture device, the floating ball carrier comprises two cross bars and two floating balls, the two cross bars are arranged in parallel, and the two floating balls are arranged separately.

Therefore, the floating ball can be more stable in heavy wind and heavy waves, can float along with the wind and heavy waves, but is not easy to turn over along with the wind and heavy waves.

More preferably, in the above laver culturing apparatus, the length of the net is 60 m to 120 m. Thus, 60 meters or more ensures the efficiency of the operation, and 120 meters or less ensures the turning at once.

Preferably, in the laver culturing device, the distance between the floating ball arms is 4-5 m. Therefore, on one hand, the number of the floating balls can be reduced, and on the other hand, the following floating balls can be ensured to be dragged and overturn along with the floating balls.

The laver culturing device created by the invention utilizes the free ends of the first cable and the second cable to be tied together and connected with the third cable, the other end of the third cable is tied on the column pile to realize fixation, meanwhile, the two third cables positioned at the front and rear ends can be used as the central shaft of the rotating device, the culturing net can be turned over manually, and the laver culturing device has the characteristics of convenient operation, very simple structure and lower manufacturing cost.

The laver culturing device of the invention manually turns over the culturing net, only one side of the front floating load or the back floating load is hooked by the pull rod to lift the far end of the cross rod and pull the far end to one side, and the whole culturing net can be turned over at one time without carrying out the same operation on each floating load, so the laver culturing device has the advantages of very simple and convenient operation and can save a large amount of time and labor.

The laver culturing device is suitable for large-scale culturing by adopting a plurality of devices, each device can be independently arranged in parallel, workers can take a boat to enter a gap between adjacent devices, and because all the front floating ball arms or the rear floating ball arms are positioned on the same side, the operation stroke can be carried out on the same side, the operation stroke can be effectively reduced, the operation time is further reduced, and the labor intensity of the workers is further reduced.

In addition, the laver culture device, the cross rod and the floating ball which form the floating ball arm can adopt two, two or more than two, and the device has a certain length, so that the culture net and the floating ball arms float along with the stormy waves in the sea, and the device has the function of resisting the floating ball arm from self overturning along with the stormy waves, and can prevent the third mooring rope from being damaged by self overturning for an unlimited time.
