The invention discloses dustproof equipment capable of protecting a LED screen. The equipment comprises a protection box, a protection cavity with a leftward opening is formed in the left side in theprotection box, a cleaning device is arranged on the upper side in the protection cavity, and the cleaning device comprises sliding cavities which are symmetrical in a front-back mode and are arrangedon the front side and the rear side of the protection cavity in a communicating mode. According to the invention, in a mode that the LED screen is subjected to heat dissipation first and then is scrubbed, the LED screen is subjected to heat dissipation through a heat dissipation device to prolong the service life of the LED screen, and dust on the surface of an LED is cleaned through the cleaningdevice to avoid manual dust removal, so that time and labor are saved, and convenience and rapidness are achieved; moreover, the equipment can further extinguish a fire of the LED screen, so that thesituation that the fire is generated to threaten life safety is prevented; and meanwhile, the equipment is further provided with a dustproof device, so that the situation that external dust falls onthe surface of the LED screen to affect the using effect and attractiveness of the LED is avoided.

The invention relates to an anti-spray device for assisting high-pressure water jet slotting. The anti-spray device comprises a packing assembly (1) and a locking assembly (2), wherein the packing assembly (1) is connected with the locking assembly (2) by threads; the locking assembly (2) comprises an outer sleeve (9), a nut (10) and an inner sleeve (11); the outer surface of the inner sleeve (11) is smoothly contacted with the inner surface of the outer sleeve (9); the nut (10) is arranged on the inner sleeve (11), and located between the outer sleeve (9) and the packing assembly (1); the upper part of the outer sleeve (9) is drum-shaped; a plurality of annular convex teeth (15) are axially arranged outside a drum-shaped sleeve wall (14); a plurality of rectangular grooves (13) are uniformly distributed in a radial direction of the drum-shaped sleeve wall (14); an opening at the lower part of the outer sleeve (9) is horn-shaped; and a plurality of rectangular openings (16) are uniformly distributed in a radial direction of a horn-shaped sleeve wall to form a bracket (17). The anti-spray device has the advantages that an incidence rate of orifice spraying can be reduced effectively, so that a great threat of transfinite gas to life safety of coal miners is avoided; a great potential safety hazard in coal mining is eliminated; and the anti-spray device is simple to operate, safe and reliable, and is of great significance in assisting the widely-used high-pressure water jet slotting to prevent the orifice spraying.

The invention relates to a communication machine room good in protective performance and facilitating air conditioner installation. The communication machine room comprises a main body and a base andalso comprises a protective mechanism and an installing mechanism, wherein the protective mechanism comprises a protective assembly and a repelling assembly, and the installing mechanism comprises a lifting assembly and a fixing assembly. In the communication machine room good in protective performance and facilitating air conditioner installation, a main body can be controlled to rise to the upper portion of the base through the protective mechanism and make snakes and rats not in contact with the main body, climbing snakes and rats are repelled through air injection. Compared with existing communication machine rooms, it is avoided that snakes and rats enter the main body to damage lines of equipment and threat the life of people, the machine room can always in a normal working state, and the people can conveniently install an air conditioner at the bottom of the machine room through the installing mechanism. Compared with the existing communication machine rooms, air conditioner installation performed by the people at high positions is avoided, the installation is quicker and more convenient and reliable, later maintenance is simple and convenient, and the practicability and reliability of the communication machine room are greatly improved.

The invention relates to outdoor lighting equipment with ice pillar preventing and supporting pillar protecting functions. The outdoor lighting equipment comprises a supporting pillar, a fixing rod and lighting lamps and further comprises an expelling mechanism and an ice removing mechanism. The expelling mechanism comprises a reciprocating assembly and a beating assembly. The ice removing mechanism comprises an extensible and retractable assembly and an air injection assembly. According to the outdoor lighting equipment with the ice pillar preventing and supporting pillar protecting functions, by means of the expelling mechanism, pets with different heights can be expelled, the pets cannot get close to the supporting pillar, and therefore the safety of a lamp pillar is guaranteed, the situation that urine of pet dogs corrodes the supporting pillar, and consequently the using of the lighting equipment is affected is prevented, and the generation of peculiar smell is avoided; by means of the ice removing mechanism, comprehensive heating ice removing can be carried out on ice pillars on the lighting lamps, generation of new ice pillars is prevented, the life threat to surrounding people from ice pillar falling is avoided, the situation that the lighting equipment is damaged by the ice pillars is prevented, and the safety and the practicality of the outdoor lighting equipment areimproved.

The invention discloses an acting part of a water-based fire extinguishing bomb. The acting part comprises a detonating device and a bomb body device, wherein the detonating device comprises an impact head and a head screw; an explosive jar, an electric igniting head, an external ignition line, a secondary induction coil, an igniting control printed board and an insulation mechanism are arranged in the head screw; the secondary induction coil, the igniting control printed board and the electric igniting head are connected to achieve an electric detonating manner; the bomb body device comprises a central fixing tube, a micro-explosion throwing and spreading device, and a housing of which the two ends are provided with openings; the micro-explosion throwing and spreading device comprises an inner ignition line, a limiting hose and an explosive tube; the micro-explosion throwing and spreading device is positioned in the central fixing tube; one end of the central fixing tube is fixed to the opening of a front blocking cover through a pressing screw while the other end of the central fixing tube extends into the housing.
