Embodiment Construction

[0007] The present invention (see accompanying drawing) is made up of 4 cun PVC pipe 2,4 cun PVC plug 1,4 change 2 PVC joint 3,2 cun water pipe 5,60 order gauze 4. The 4-inch PVC pipe 2 is 50cm in length, one end is sealed with a 4-inch PVC plug, and the other end is connected with a 4-variable 2PVC connector. The other end of the 4 variable 2PVC connector is connected to a 2-inch water pipe. The surface of the 4-inch PVC pipe and the 4-inch PVC plug is evenly punched with several holes with a diameter of 1 cm, and the entire 4-inch PVC pipe and the 4-inch PVC plug 1 are wrapped with a 60-mesh gauze.

[0008] When the device is in use, put the whole 4-inch PVC pipe and 4-inch PVC plug wrapped by 60-mesh gauze 4 into the nursery pond gently, and use the siphon method to transfer the water in the nursery pond through 4 to 2 PVC joints and 2-inch plugs. Hose drained. When the drainage is finished, first raise the water outlet of the 2-inch water pipe so that it is higher than t...

Abstract

The invention discloses a device capable of reducing water flow impact force in aquaculture, relates to a water draining device during fry breeding of aquaculture, and aims to provide a water drainingdevice capable of reducing the water flow impact force. The device comprises a 4-inch PVC (polyvinyl chloride) pipe, a 4-inch PVC plug, a 4-to-2 PVC joint, a 2-inch water pipe and a 60-mesh gauze screen. The device is characterized in that the one end of the 4-inch PVC pipe is connected with the 4-inch PVC plug, the other end of the 4-inch PVC pipe is connected with the 4-to-2 PVC joint, the 2-inch water pipe is connected with the 2-inch end of the 4-to-2 PVC joint, a plurality of holes with the diameter of 1cm are formed in the surfaces of the 4-inch PVC pipe and the 4-inch PVC plug, and the60-mesh gauze screen wraps the whole 4-inch PVC pipe and the surface of the 4-inch PVC plug.

Description

technical field [0001] The invention relates to a drainage device during aquaculture seedling raising. Background technique [0002] Aquaculture nursery is an important link in the entire aquaculture industry, and the survival rate of the nursery is directly related to the economic benefits of the aquaculture industry. As we all know, there are many factors that affect the survival rate of aquatic seedlings, such as water quality, temperature, light and so on. However, the daily maintenance work during the nursery period, such as changing the water operation, is also one of the important factors affecting the survival rate of aquatic seedlings. Because, in the early development stage, the seedlings are extremely vulnerable to the stress of external factors and die. Improper water changes can cause a stress response in the seedlings resulting in high mortality. Therefore, how to minimize the stress death of seedlings caused by water exchange during aquaculture breeding is ...
