The invention discloses a push-pull type steel-structured airtight protective door. The push-pull type steel-structured airtight protective door comprises a door sash, a rolling wheel, a door frame, sealing rubber strips on the periphery of the door frame, a locking linkage mechanism, an outer side guide roller mechanism, a ditch cover plate opener and a steel guide rail for movement of the rolling wheel. The two sides of the door sash are respectively provided with an inner side guide roller mechanism. The inner side guide roller mechanisms are matched with the locking linkage mechanism to enable sealing embedded and pressed strips on the door sash to be integrally embedded or exit out of inlaid grooves of the sealing rubber strips, so smooth opening of the door sash can be guaranteed. A manual traveling wheel mechanism can guarantee that the large-size door sash slides lightly and conveniently in the opening process. The small airtight protective door brings convenience for a small amount of people to go out and come in. The push-pull type steel-structured airtight protective door is used for integrated entrances and exits for subways and civil defense, and solves the problem that the large-size airtight protective door is difficult to be airtight and move. The push-pull type steel-structured airtight protective door is simple in structure, convenient to operate, low in manufacturing cost, safe to use, obvious in war preparedness benefit, economic benefit and social benefit, wide in popularization and application prospect, and reduces huge workload in peacetime and wartime conversion.

The invention relates to a system and method of actively capturing a low altitude small unmanned aerial vehicle, wherein an unmanned aerial vehicle platform is used for realizing low altitude flight, and is provided with a binocular vision image acquisition unit and an ejection capturing unit. The binocular vision image acquisition unit is used for shooting binocular video image information in a monitoring space; a multi-information collection unit is used for obtaining the inclination angle information, height information and / or geographical position information of the unmanned aerial vehicle platform; an information processing decision unit is used for fusing the binocular vision image information and the inclination angle information, height information and / or geographical position information, and calculating and analyzing air vehicle detection identification, depth information obtaining, air vehicle tracking, and air vehicle capturing commands; the ejection capturing unit captures air vehicles according to the air vehicle capturing commands. The system and method improve the capability of actively capturing invasive small low altitude small unmanned aerial vehicles.

The invention discloses a sand filling machine construction method for water island reef blow-filling construction. The reef sand receiving bucket is installed on the top of the vibrating screen, the vibrating screen is installed on the top of the platform, and the outer wall of the water flow separation tank is provided with a reef sand breaking device. Broken mixing tank, the broken mixing tank is fixed on the top of the platform, the bottom of the drying pipeline is connected with the mixing tank, the top of the mixing tank is provided with a drying box; the four corners of the bottom of the platform are equipped with rollers, and the rollers Supported on the track of the reclamation area, a vibration buffer device is installed at the bottom of the platform; the bottom of the mixing tank is connected with a rotatable sand discharge port. The reef sand with larger particle size is crushed and stirred by the rotating fan blade of the sand filling machine, so that the reef sand particles with large particle size are broken and smaller, which increases the crushing stress of the reef sand in the later stage, and greatly reduces the impact of the upper reef sand on the bottom reef sand during later filling. The possibility of breaking due to the increase of gravity, so as to avoid a series of engineering problems such as ground subsidence and ground cracks in the later stage.

The invention relates to an underground mineral mining method and discloses a working face mining method. The mining process comprises the following steps of before mining, performing constructing onworking faces to form a cut hole so as to form a starting point of mining on the working faces; and performing gob-side entry retaining while mining at the two ends of each working face to respectively form a first gate way and a second gate way, wherein the first gate way and the second gate way form ventilation and transportation channels of the working faces. The mining method for bilateral entry retaining has the advantages and positive effects that compared with the prior art, the underground mineral mining method can ensure the ventilation of a whole coal mining area without the need ofperforming tunneling around the mining area to prepare a roadway; the gate ways do not need to be tunneled in advance when each working face in the mining area is mined, but the gate ways are formed after coal mining, thereby greatly reducing the huge workload caused by tunneling the gate ways in advance and greatly shortening the well construction period; and simultaneously, no coal pillars needto be reserved, thereby saving resources.

The invention relates to a method for allocating addresses of communication equipment and counting the number of equipment, including several equipment and a monitoring system. The communication line of each equipment is divided into an input terminal IN and an output terminal OUT, and each equipment is connected in a line type. The terminal IN is connected with the monitoring system, and the input terminal IN of each subsequent device is connected to the output terminal OUT of a device; each device is controlled by a switch J to turn on and off the output terminal OUT; the communication device address assignment and device The method of quantity statistics includes step 1: the monitoring system sends a switch disconnection command; step 2: the monitoring system sends an address setting command to set the address of the first device; step 3: repeat step 2 until the device at the end of the communication line; step 4: carry out total. The present invention ensures that each device is uniquely corresponding to the address signal by distributing the address signals of the devices one by one. During the process of distributing the address signals, the device quantity is counted at the same time, reducing the huge workload of manual confirmation.
