Manual water injection and suction pump for sinking-floating fishing net

Abstract

The invention discloses a manual water injection and suction pump for a sinking-floating fishing net. The manual water injection and suction pump for the sinking-floating fishing net comprises a pumpbody and a supporting plate, wherein supporting legs are fixedly connected to two sides of the bottom of the supporting plate correspondingly; supporting rods are fixedly connected to two sides of thetop of the supporting plate correspondingly; limiting rings are fixedly connected to the top ends of the two supporting rods correspondingly; the bottom of the pump body communicates with a connecting pipe; and the bottom of the connecting pipe penetrates through the limiting rings and the supporting plate and extends to the bottom of the supporting plate. The manual water injection and suction pump for the sinking-floating fishing net provided by the invention relates to the technical field of water suction pumps. According to the manual water injection and suction pump for the sinking-floating fishing net, in the using process, a movable plate drives a sealing plug to move upwards under the action of water pressure, so that a water flow can flow out smoothly; when the manual water injection and suction pump is not used, a sealing plug can seal the top end of the connecting pipe under the action of a resilience force of a spring, water in the pump body is prevented from running off,and water in the sinking-floating finishing net can be pumped out without the need for adding water when the manual water injection and suction pump is used for the next time, so that the manual waterinjection and suction pump for the sinking-floating fishing net is convenient to use; and the pump body can be detached from the supporting plate, so that the convenience in moving and transporting is achieved, and the practicability is improved.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a manual water injection pump for sinking and floating fishing nets. Background technique [0002] The sinking and floating fishing net is one of the tools for fishing in fish ponds or rivers. Its working principle is that there is a water-injection net tire on the edge of the fishing net. When placing the fishing net, first inject water into the water-injection net tire through the water injection pipe. Thereby completing the network. When lifting the net, it is necessary to slowly pump out the water in the water-injected net tire until the water-injected net tire emerges from the water surface. Since the water-injected net tire is set on the edge of the fishing net, a concave net with the edge on the water surface and the middle part under the water is formed. It is convenient to catch fish from the net. This kind of net is a kind of high-efficiency fishing net designed f...
