Trepang catching device

Abstract

The invention relates to a trepang catching device which comprises a driving device and the like. The driving device comprises storage batteries, an underwater motor control switch and an underwater motor which are electrically connected in sequence. The driving device further comprises a propeller arranged at the rear end of a floating body, wherein the shaft of the propeller is connected with the output shaft of the underwater motor, the floating body is arranged on a floating body frame, and a monitor is connected onto the floating body frame. A rope is connected onto the floating body frame, an anchor body is connected with the rope, and the lower end of the middle of the floating body frame is connected with a foot stepping frame. An inlet is formed in the upper end of a trepang cage, an elastic blocking strip is arranged on the inlet, and the trepang cage is connected onto the floating body frame through a trepang cage lifting rope. One end of a mechanical claw return spring is connected with the rear end of the foot stepping frame, the other end of the mechanical claw return spring is connected with the middle of a manual control mechanical claw, a rod portion of the manual control mechanical claw penetrates through the floating body frame, a handle connected with the upper end of the rod portion extends out the upper end of the floating body frame, a clamping claw connected with the lower end of the rod portion extends out of the bottom end of the floating body frame, and an underwater camera is arranged on the front side of the manual control mechanical claw.

Description

technical field [0001] The invention relates to a harvesting device, in particular to a harvesting device for sea cucumbers. Background technique [0002] In recent years, sea cucumber has gradually become one of people's favorite tonic products due to its high nutrition, high protein, and low fat characteristics. People have invested in sea cucumber farming, but the fishing of sea cucumbers is another problem. [0003] Sea cucumber fishing is divided into seasons. In winter, the water temperature is too low. Sea cucumbers metabolize slowly without eating, and they will hide in reef holes and do not move. Sea cucumbers need to sleep in summer, so they are not suitable for fishing. Sea cucumbers only come out to look for food when the water temperature rises in spring and autumn every year, and it is suitable for fishing at this time. [0004] The traditional harvesting method is manual harvesting. Divers carry oxygen tubes and oxygen masks to dive to the bottom of the sea ...

Problems solved by technology

[0004] The traditional harvesting method is manual harvesting. Divers carry oxygen tubes and oxygen masks to dive to the bottom of the sea to fish. The fishing bag usually needs to be hung around the neck of the diver. After a certain amount is harvested, the diver comes out of the water with the fishing bag and removes it. It is very troublesome to pour it into the fishing boat; moreover, the seawater pressure is strong, the labor intensity is high, and it is very dangerous. Long-term underwater fishing will cause great harm to the human body; hiring divers also requires a lot of money, and the cost is high. The number of arrests is not satisfactory
