Embodiments of the present specification provide a hull-shaped unmanned submersible rescue robot for underground mines, comprising: a robot body; a sensing module; and a control device; wherein the sensing module is connected to the control device; wherein the control device is located in the robot body and is connected to a drive device of the robot body; wherein the sensing module comprises a pressure sensor and a thermal imaging sensor; wherein the pressure sensor is located at an outer bottom of the robot body, and the thermal imaging sensor is located at an outer sidewall of the robot body; wherein the pressure sensor is configured to sense a draft of the robot body and transmit the draft to the control device; and wherein the thermal imaging sensor is configured to sense a position of each individual around the robot body and transmit the position of each individual to the control device. The hull-shaped unmanned submersible rescue robot for underground mines according to the embodiments of the present disclosure is not limited by communication signals, is capable of automatically responding and searching for and rescuing personnel in the underground mines at the first time after a water inrush occurs in the underground mines, improves water inrush emergency rescue capability, and increases a survival probability of trapped individuals in the underground mines.

This invention relates to the field of deck fencing technology and discloses a combined structure of a deck fencing and equipment support. The structure includes an antenna mast, reinforcing rods, crossbars, a searchlight bracket, and a horn bracket. The antenna mast and reinforcing rods are fixed to the deck surface, and the crossbars connect the antenna mast and reinforcing rods to form a fencing along the edge of the deck surface. The upper end of the antenna mast is used to fix the antenna, and the searchlight bracket and horn bracket are respectively installed on the outer side of the crossbars. The searchlight bracket includes a first base plate, a rotating shaft, and a fan-shaped transmission structure. The rotating shaft is rotatably mounted on the crossbar, and the first base plate is fixedly connected to the rotating shaft. The fan-shaped transmission structure is anti-rotatingly connected to the rotating shaft, and its center is concentric with the central axis of the rotating shaft. The fan-shaped transmission structure is also connected to a driver to drive the first base plate and the searchlight to adjust their pitch angle. The horn bracket includes a second base plate and a reinforcing plate. The reinforcing plate is fixed between the second base plate and the reinforcing rod, and the second base plate is used to fix the horn.
