The invention provides an anti-explosion fire rescue door which comprises a vertical hinged door, a door leaf limiting mechanism and a rescue overturning table; the vertical hinged door comprises a door frame arranged on a wall body and a door leaf hinged to the door frame through a plurality of anti-explosion hinges, and the door leaf is provided with a door lock allowing people to open from the outer side of the wall body; the door leaf limiting mechanism is used for restraining the door opening angle of the door leaf opening towards the outer side of the wall body; and the rescue overturning table comprises a standing plate, one side of the standing plate is hinged to the bottom of the door frame, the other side of the standing plate is provided with a protective fence structure allowing people to pass through, and a swing restraining structure is arranged between the standing plate and the vertical hinged door. According to the invention, personnel can conveniently open the door leaf from the outer side of the wall body by using a conventional means and quickly build the rescue overturning platform extending out of the wall body, so that the safety of the personnel and equipment is better ensured, and safe and reliable conditions are provided for quick rescue actions.

The invention discloses a multi-ball point pre-buried pile for geological disaster early warning, which belongs to the field of geological disaster early warning. It is a multi-ball point pre-buried pile for geological disaster early warning. Through the setting of the pre-buried pile, when the geological subsidence occurs, The pre-breaking sinking rod is subjected to downward pressure, and acts on the lower outer marking end, so that the surface of the marking ball is notched, and the colored sand inside overflows. When the pre-breaking sinking rod breaks, the outer marking end recovers after losing the pressing force. , the gap disappears, and the sand mining stops overflowing. When the pre-embedded pile detects that there is subsidence, the soil near the pre-embedded pile can be excavated, and the specific subsidence situation can be judged according to the amount of colored sand. , the sharp thorns gradually approach the inner photosphere until it will pierce, causing the fluorescent liquid inside to overflow, which can be used for auxiliary marking of geological subsidence, which will help the staff to intuitively judge the situation of geological subsidence, and facilitate corresponding Countermeasures to reduce potential safety hazards.

The invention discloses an anti-twisting automatic bale plucker which comprises a cotton conveying pipe, a stretchable pipe, a suction bin hopper, a bale plucking roller, a supporting plate, a top plate, a trolley, a sliding ring, an inner ring wallboard and an outer ring wallboard. The cotton conveying pipe is connected with the top of the stretchable pipe. The lower end of the stretchable pipe is connected with the top of the suction bin hopper. A material sensing sensor is arranged on the side wall of the suction bin hopper. A bale plucking roller is installed inside the suction bin hopper. A plurality of bale plucking fluted discs are evenly distributed on the bale plucking roller in the axial direction. The number of plucking teeth arranged on the bale plucking fluted discs is the multiple of 3, one third of the plucking teeth and the bale plucking fluted discs are on the same plane, the other two plucking teeth adjacent to the plucking teeth on the same plane of the bale plucking fluted discs are bent towards the two sides of the axial direction respectively, and a driving motor for driving the bale plucking roller is installed on the suction bin hopper. The anti-twisting automatic bale plucker is simple in structure, uniform in peeling cotton suction, capable of achieving intelligent motion cotton suction, capable of effectively preventing the bale plucking roller from being twisted by cotton, and capable of improving the working efficiency.
