Description

Anti-blocking water quality sampling device for aquaculture

Technical Field

The invention relates to the field of aquaculture, in particular to an anti-blocking water quality sampling device for aquaculture.

Background

The yield of aquaculture in the world is rapidly increasing since the 70 s in the 20 th century, the specific gravity in aquaculture is increasing day by day, and the history of freshwater aquaculture in China dates back to 11 th century before the first of the Gongyuan. The "fish culture" was published 5 th century before the Yuan. There are two main types of freshwater aquaculture: firstly, the cyprinid fishes are intensively cultured in the pond to obtain high yield by feeding and fertilizing, and various fishes with different feeding properties are mixedly cultured to give full play to the productivity of the water body. The other type is to breed seedlings in large and medium-sized water areas such as lakes, reservoirs, ditches, rice fields and the like, and aquatic products are obtained mainly by means of natural baits.

For guaranteeing that the suitable aquatic products of quality of water in the breed pond grow and breed, need carry out periodic sampling test to quality of water, but current sampling device carries inconveniently, and the inside pasture and water of pond can block up the sample connection when the sample simultaneously, causes sampling speed slow, and current sampling device can't carry out the layering sample simultaneously to can't carry out accurate analysis to the quality of water of each layer of pond inside.

Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Referring to fig. 1-2, an anti-blocking water quality sampling device for aquaculture comprises a hollow rod 1, a main rod 4, a round-head bottom rod 6, a fixed cylinder 7, a sampling bottle 8 and an isolation filter screen 14, wherein handles 2 are symmetrically welded on two sides of the hollow rod 1 to facilitate handling of the sampling device, an upper buckle 3 is connected to the lower side of the hollow rod 1 through threads, the main rod 4 is arranged on the lower side of the upper buckle 3, the upper buckle 3 is connected with the main rod 4 through a welding mode, the hollow rod 1 and the main rod 4 are both hollow structures, a lower buckle 5 is further welded on the lower side of the main rod 4, the upper buckle 3 and the lower buckle 5 are of the same type, the inner parts of the upper buckle 3 and the lower buckle 5 are also hollow structures, the lower side of the lower buckle 5 is connected with the round-head bottom rod 6 through threads, the isolation filter screen 14 is arranged between the upper buckle 3 and the lower buckle 5, the isolation filter, therefore, sundries such as aquatic weeds and the like in the culture pond are prevented from entering the sampling device during sampling, the blockage of a sampling port of the sampling device is effectively avoided, and the water quality sampling speed is improved; the outer wall left and right sides interval of mobile jib 4 is equipped with fixed cylinder 7, through screw fixed connection between the outer wall of fixed cylinder 7 and mobile jib 4, 7 inside slidable mounting of fixed cylinder have a sample bottle 8, and 8 upside central points of sample bottle put and open there is the sample connection, 8 upsides of sample bottle still are equipped with drag hook 9, are connected with stay cord 12 on the drag hook 9, 7 upsides of every fixed cylinder of group all are equipped with outer guide pulley 10, and outer guide pulley 10 is installed on the 4 outer walls of mobile jib, the inside guide pulley 11 that still corresponds of mobile jib 4 installs, stay cord 12 is worn out mobile jib 4 and hollow pole 1 after outer guide pulley 10 and the 11 direction of inner guide pulley in succession, and the 12 other ends of stay cord are connected with.

The working principle of the invention is as follows: when the water quality in the culture pond needs to be sampled, the circular pull ring 13 is lifted upwards, then the sampling device is stretched into the culture pond, after the position is proper, the circular pull ring 13 is gradually loosened, the sampling bottle 8 is gradually separated from the fixed cylinder 7 under the action of the gravity of the sampling bottle 8, when the sampling port of the sampling bottle 8 is contacted with the outside, water enters the sampling bottle 8 from the sampling port, the circular pull ring 13 is lifted upwards after a period of time, the sampling bottle 8 is installed in the fixed cylinder 7, then the sampling device is integrally lifted upwards, the water in each sampling bottle 8 is poured into a respective detection bottle after the sampling device is integrally taken out, after the sampling process is finished, the isolation filter screen 14 is arranged to prevent sundries such as aquatic plants in the culture pond from entering the sampling device during sampling, so that the blockage of the sampling port of the sampling device is effectively avoided, and the sampling speed of the water quality is improved, meanwhile, the water quality of each layer in the aquaculture pond can be sampled simply and effectively, so that water samples of each layer are comprehensively detected and analyzed, the water quality condition of the pond is accurately known, and the normal propagation and growth of aquatic products are guaranteed.
