The invention discloses an uneven humid efficient phase changing coating preparation and a gravity assisted heat pipe device. The gravity assisted heat pipe device comprises a pipe body with two sealed ends; liquid working medium is poured into the pipe body; the upper portion of the pipe body is a condensation section, and the lower portion of the pipe body is an evaporation section; the inner top wall of the condensation section is a zigzag-shaped structure face; the uneven humid coating covers the inner side wall of the condensation section, the zigzag-shaped structure face and the inner bottom face of the evaporation section; the uneven humid coating comprises dewatering areas and hydrophilic areas; the uneven humid coating covering the zigzag-shaped structure face of the condensation section is of the structure that the straight stripes of the dewatering areas and the hydrophilic areas are distributed alternately; and the direction of the straight stripes is perpendicular to the zigzag grooves of the zigzag-shaped structure face. The gravity assisted heat pipe device can improve heat flux of an evaporation process and a condensation process remarkably. According to gravity assisted heat pipe device, depending on the operation rules of gravity assisted heat pipes, drawbacks existing in current gravity assisted heat pipes are overcome; working medium cycling speed is improved; and heat transfer load of the heat pipes is strengthened.

The invention discloses a board cutting platform. The board cutting platform comprises a supporting board; a positioning board is fixedly connected to the left side of the bottom of the supporting board, and a storage box is fixedly connected to the right side of the bottom of the supporting board; a collecting box is arranged in the storage box; a fixing board is fixedly connected to the right side of the top of the supporting board; a sliding block is arranged on the left side of the fixing board; and the top of the sliding block is connected with sliding rails in a sliding mode. Through cooperative use of the supporting board, the positioning board, the storage box, the collecting box, the fixing board, the sliding block, the sliding rails, a hollow block, a positioning block, a brush,a positioning rod, a bolt, a limiting board, an antiskid sleeve, an opening and a feed inlet, the problem that an existing cutting platform cannot collect waste in the using process is solved. The board cutting platform has the advantage of collecting waste, thereby reducing unnecessary resource waste, reducing the economic losses of users and being convenient to use by the users.

The invention relates to a multifunctional coal mine safety detection bar for detecting spontaneous combustion hidden trouble points of coal seams and a manufacturing method thereof. The multifunctional coal mine safety detection bar comprises an outer sleeve, a middle sleeve, an inner sleeve, a mine thermometer, a tail end plug and a front end plug, wherein the outer sleeve is of a hollow structure, and internal threads are arranged on the inner walls of the two ends of the outer sleeve; the middle sleeve is of a hollow structure, one end of the middle sleeve is connected with the outer sleeve and is provided with external threads, and the other end of the middle sleeve is provided with internal threads; the inner sleeve is of a hollow structure and is provided with external threads matched with the internal threads of the middle sleeve, and the other end of the inner sleeve is provided with a detection head; the mine thermometer is installed at one end of the inner sleeve close to the detection head; the tail end plug is connected with the outer sleeve through threads and is provided with a through hole for connecting an airbag; and the front end plug is connected with the other end of the outer sleeve through threads and is provided with a pit matched with the mine thermometer. The multifunctional coal mine safety detection bar has multiple functions of measuring coal seam temperature, collecting gas, being used as a walking stick for walking in a tunnel, and the like; the multifunctional coal mine safety detection bar has a retractable structure and is low in cost, simple and easy to use, exquisite and beautiful as well as fast and convenient; and the multifunctional coal mine safety detection bar is made of aluminum alloy, and then the weight of the traditional long rod made of iron is relieved, so that the multifunctional coal mine safety detection bar is portable and is convenient to use.

The invention provides a high-effective gas-water separator, which includes a tube head, a tube body, a flow guide part, a secondary separation flow guide trough, a water fog and oil fog collector, and an air oriented flow guide device. The tube head includes a tube body connection port and a flow guide connection port arranged on the lower end of the tube head, a gas inlet arranged on the front end of the tube head, and a gas outlet arranged on the back end. The flow guide connection port is connected to the upper part of the flow guide part. An assembling position of the secondary separation flow guide trough is disposed in the middle of the flow guide part. A circular cylinder, of which the interior is circular and the exterior is trough-like in shape, is designed at the lower end port. The secondary separation flow guide trough is connected to the middle part of the flow guide part through the assembling position of the secondary separation flow guide trough in a sleeving manner. The water fog and oil fog collector and the air oriented flow guide device successively sleeve the flow guide part and are arranged above the secondary separation flow guide trough. The inner wall of the tube body sleeves the circular cylinder, of which the interior is circular and the exterior is trough-like in shape, of the flow guide part; and the outer wall of the tube body is arranged through the flow guide part and the secondary separation flow guide sleeving the flow guide part. The water fog and oil fog collector and the air oriented flow guide device are then connected to the tube body connection port at the lower part of the tube head.
