The utility model discloses a grabbing type sea cucumber fishing robot. The sea cucumber collecting robot comprises a robot frame, a five-degree-of-freedom mechanical arm and a sea cucumber collecting device, a mechanical arm base and a sea cucumber collecting device are fixedly arranged on the top of the robot frame, a sealing bin is fixedly arranged at the bottom of the robot frame, and vertical propellers and horizontal propellers are fixedly arranged on the periphery of the robot frame. And the synchronous pulley II is driven by the stepping motor I to realize the rotary motion of the mechanical arm. According to the underwater robot, the five-degree-of-freedom mechanical arm and the eight-shaft propeller are adopted, and free movement and flexible grabbing of the robot under water are achieved. The sea cucumber catching robot can replace manpower to catch sea cucumbers and is not limited by seasons. The water pressure borne by the device is far higher than that borne by human beings, so that the device has higher safety. The sea cucumber catching robot is used for replacing manual work, and potential hazards of the marine environment to the body health of a caught person are effectively avoided.

A photovoltaic roof water surface mounting device disclosed by the present invention comprises a roof panel and a photovoltaic support, the top of the roof panel is provided with a plurality of ribs parallel to each other, the photovoltaic support is fixedly erected above the ribs through a plurality of adapter clamps, the photovoltaic support is provided with a plurality of photovoltaic panels, the plurality of photovoltaic panels are arranged along the length direction of the photovoltaic support, and the adapter clamps are fixedly arranged on the photovoltaic support. The adjacent photovoltaic panels are connected through a first locking device, and the outer sides of the photovoltaic panels at the head end and the tail end are fixedly connected with the photovoltaic support through a second locking device. According to the invention, the photovoltaic support is rapidly and stably connected to the convex edge of the roof panel through the arranged switching clamp; through the arrangement of the first locking device, automatic locking connection between two adjacent photovoltaic panels can be realized only by pushing the photovoltaic panels in place, and screws do not need to be turned frequently for fixation; the photovoltaic panels at the head end and the tail end are tightly connected to the photovoltaic support through the arranged second locking device, the photovoltaic panels are easy and convenient to install, time and labor are saved, and the installation efficiency is improved.
