Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0012] figure 1 Among them, the power pump (1) provides water as power for the whole set of facilities, the water inlet of the power pump (1) is the power pump inlet (2), and the power pump outlet (3) is connected to the water inlet (5) through the water inlet pipe (4), The water-absorbing fishing device (8) is connected on the Venturi retaining pipe (6), and the Venturi retaining pipe (6) is installed in the mixing chamber (7), and the mixing chamber (7) is connected with the filter fishing net (9).

[0013] combine figure 2 The schematic flow diagram of the entire set of devices in the middle tells the embodiment. When fishing starts, the water flow provided by the power pump (1) enters the water inlet (5) through the water inlet pipe (4) and then forms the inlet water flow (101) of the mixing chamber. Under the action of (6), the Venturi ...

Abstract

The invention discloses a novel trepang fishing device. During trepang fishing, power water provided by a power pump is conveyed to a water inlet through a water inlet pipe, the pressure difference between the conveyed power water and a water suction fishing pipe is used for producing suction force through a venturi nozzle so that the water suction fishing pipe can suck and discharge aquatic products needing to be fished to a fishing net. After water is filtered out, the aquatic products are caught. The efficiency of manual one-by-one picking fishing is improved, the underwater diving time of workers is shortened, risks and the workload are reduced, the whole device can be installed on an underwater robot to serve as a fishing device of the underwater robot, the workers do not need to enter the water to conduct fishing, and the workload and risks of manual fishing are reduced.

Description

technical field [0001] The invention relates to an aquatic fishing device, in particular to a new sea cucumber aquatic fishing device. Background technique [0002] Sea cucumbers generally live on the bottom of the sea with a water depth of about 10-20 meters. Because there are many reefs in their growth environment and they are on the bottom of the sea, they cannot be fished with nets. At present, sea cucumber fishing mainly depends on divers wearing oxygen masks and nets to dive into the seabed for manual harvesting. Harvesting sea cucumbers is troublesome and dangerous. At the same time, because sea cucumbers are harvested in spring and autumn, and the seawater temperature is very low, divers are prone to occupational diseases such as arthritis and rheumatism due to long-term sea cucumber harvesting. [0003] The economic value and nutritional value of wild sea cucumbers are much higher than those of artificial breeding. At present, wild sea cucumbers are fished one by ...
