The invention discloses an air-conditioning ventilation system for an anti-explosion place of a ship and a control method thereof. The air-conditioning ventilation system comprises an independent airconditioner external unit arranged outside a cabin of the anti-explosion place, an anti-explosion air conditioner internal unit, an air-entering electric ventilation door and an air exhausting mechanism which are arranged in the cabin; the independent air conditioner includes a refrigeration assembly and an electric control box, and the anti-explosion air conditioner internal unit includes an evaporator, a thermostatic expansion valve, an anti-explosion draught fan, an electric heater, and a temperature sensor for detecting the air-returning temperature in the cabin of the anti-explosion place; and the refrigeration assembly communicates with the evaporator through a refrigerant pipe penetrating through a bulkhead, and the thermostatic expansion valve is fixed at an entrance of the evaporator. The control method comprises two control modes including a manual operation mode and an automatic mode, through the combined control of air conditioning and ventilation, the requirement of the storage temperature of anti-explosion items is ensured, long-time accumulation of flammable and explosive gas is avoided, the safety of the anti-explosion cabin is ensured, and the control method is high in degree of automation, simple in logic setting, easy to operate and reliable in control.

The invention discloses an electromechanical time fuze for an anti-aircraft gun hail-proof and rain-increasing bomb, which comprises an upper body 1, a wind cap 2, an electromechanical timing firing mechanism 3, a fuze body 4, a ball rotor safety and release safety mechanism 5, and a detonator tube 7. The hood 2 covers the front end of the upper body 1, and its bottom opening is fixed in the outer annular groove of the upper body 1. The electromechanical timing ignition mechanism 3 includes a magnetic recoil power supply and an electronic timing and firing module, located inside the cavity of the upper body 1 , the rear end is adjacent to the non-priming detonator 17, the ball rotor safety and release mechanism 5 is located in the inner cavity of the fuze body 4, the top is adjacent to the non-priming detonator 17, and the front end of the detonator 7 protrudes Part is adjacent to the ball rotor safety and disengagement mechanism 5, and the rear end is used as the fuze output end for detonating the projectile charge. The electromechanical time fuze of the anti-aircraft artillery hail-proof and rain-increasing bullet of the invention has accurate timing, good productivity and high reliability.

The invention discloses a skid-mounted pump set device comprising a housing and a skid-mount base. A door and a ventilation window are arranged on the housing. An exhaust fan is arranged in the housing. An electric control cabinet and an instrument cabinet are arranged in the housing. Pump set units are arranged in the housing. The skid-mount base is an I-shaped steel part. The pump set units are fixed on the I-shaped steel part through bolts. A lug is fixed on the skid-mount base. In the device provided by the invention, the skid-mount base and the housing are integrated through bolts, and the pump set units are fixed on the skid-mount base. When in use, the housing or the skid-mount base is suspended, such that the movement of the entire device can be realized. Compared with prior arts, only one time of mounting is needed. The device has the advantages of small land occupation, and can be subjected to centralized management. Explosion-proof safety is increased.

The invention discloses an inertial memory alloy composite rotor-type isolation mechanism, and belongs to the technical field of fuse safety mechanisms. The isolation mechanism comprises a body provided with a rotor hole, and a rotor nested in the rotor hole, wherein holes for accommodating a memory alloy pin pusher, an inertia safety component, a lock pin, a change-over switch, a fire propagation component, an explosion propagation component and other components are formed in the rotor and the body; and the isolation mechanism has a large isolation termination rotation angle through optimization for the structure components and optimization for the positions of the holes, the state of the isolation mechanism can be accurately identified and fed back, and locking for the isolation mechanism in each state in the state is ensured. According to the isolation mechanism disclosed by the invention, through the abovementioned arrangement, on one hand, the safety of the mechanism in a safe state is guaranteed, and the alignment of a detonation sequence in an arming state is ensured, so that the detonation efficiency is greatly increased; and on the other hand, the state of the isolation mechanism can be effectively identified and fed back to a control system by the change-over switch and other components, so that the safety of the isolation mechanism is further improved, and the detonation efficiency is further increased.
