Intercepting device for external water inlet of aquaculture pond

Abstract

The invention relates to an intercepting device for the external water inlet of an aquaculture pond. The device comprises two vertical piles. A lateral hanging cable is fixedly arranged between the top ends of the two vertical piles. A plurality of netting hanging rings are penetrated through the lateral hanging cable. The netting hanging rings are sewn with fixed nettings. A netting hanging ring stay rope, a left net bottom stay rope, a right net bottom stay rope and an intermediate net bottom stay rope respectively pass through each of the plurality of netting hanging rings. Each netting hanging ring stay rope is respectively and fixedly provided with a netting hanging ring latch hook. The left net bottom stay rope, the right net bottom stay rope and the intermediate net bottom stay rope are respectively and fixedly connected with a netting left lifting cable, a netting right lifting cable and a netting intermediate lifting cable of the netting bottom, corresponding to the left end, the right end and the intermediate part of the netting bottom. The bottom edge of the netting is sewn with a sinking pressure bag filled with broken stones. According to the invention, a blocking netting can be pulled at a shore side to be cleaned at any time. Therefore, the requirements of aquaculture wastewater can be met more elaborately.

Description

technical field [0001] The invention belongs to the technical field of aquaculture pond equipment, in particular to an intercepting device for an external water inlet of an aquaculture pond. Background technique [0002] In recent years, my country's aquaculture industry has developed rapidly. Fish farming starts with raising water. The quality of water is the key factor for the success of aquaculture. In the process of pond aquaculture, ensuring the quality of influent water in the early stage can improve the success rate of aquaculture. In the process of pond breeding, the wild fish in the pond are often cleaned with advanced water and drugs such as tea seed cake and trichlorfon. On the one hand, this cleaning method cannot guarantee the cleaning effect. It is very harmful to the cultured species, and it will bury hidden dangers for future breeding, and the effect is not ideal. At present, although some breeding units have added a blocking device at the water inlet outsid...

In the process of pond breeding, the wild fish in the pond are often cleaned with advanced water and drugs such as tea seed cake and trichlorfon. On the one hand, this cleaning method cannot guarantee the cleaning effect. It is very harmful to the cultured species, and it will bury hidden dangers for future breeding, and the effect is not ideal

At present, although some breeding units have added a blocking device at the water inlet outside the breeding pond, such as figure 1 As shown, it includes a plurality of fixed poles 1 in the water inlet, a horizontal hanging bar 2 for hanging the block, a block 3 suspended on the hanging bar, a drop bag 4 at the bottom of the block and a crushed stone bag 5 in the drop bag. , the block with this structure can only intercept relatively large pollutants. If in order to intercept relatively small pollutants, the mesh of the block should be designed denser. In this way, the mesh of the block will be quickly blocked by pollutants, reducing the water intake. The flow may almost block the water intake, and the block with this structure can hardly clean the dirt. If it needs to be cleaned, it must be completely removed and reinstalled, which is time-consuming and laborious
