The production process of flame-retardant shaped bamboo material includes the steps of: cutting bamboo into bamboo sheet, soaking in preservative and steaming antisepsis, cutting dried bamboo sheet into bamboo filament, soaking the bamboo filament in flame-retardant liquid comprising phosphate ester and boric acid or borax, dewatering, soaking in the waterproof adhesive, drying, compression setting inside mold in over 50 MPa hydraulic press, solidification and cooling to set in a drying kiln, and demolding. In case of burning the bamboo material, the high temperature will make the formed bamboo material blacken and coke without flame. The flame-retardant shaped bamboo material is anticorrosive, waterproof, high in strength and high in toughness, and may be used as floor, wall and other building material.

The invention discloses a press buckle type rock wool composite board and a manufacturing method thereof, and belongs to the technical field of heat insulation material preparation. The composite board comprises rock wool base body layers, a reinforcing layer, a surface layer and a press buckle structure, wherein the reinforcing layer is arranged between the rock wool base body layers in a clampedway, and achieves the effects of supporting and reinforcement; the intensity of the rock wool base body layers is well enhanced, so that the overall intensity of the rock wool base body layers is improved by at least 100 times or higher; the surface layer is connected with the reinforcing layer through the press buckle structure, and is tightly attached onto the rock wool base body layer. Throughthe designed structure, the mode that the surface layer is adhered by polymer cement mortar in the prior art is changed; the polymer cement mortar is not used as much as possible; the emission of benzene and benzene derivatives is reduced; the use of the composite board is safer and more reliable; the heat insulation, sound insulation and fireproof effects are obvious.

The invention relates to a manufacturing method for fireproof glass cotton. The manufacturing method comprises the steps of: (1) selecting 65-75 parts by mass of glass cullet, 6-9 parts by mass of feldspar powder, 4-6 parts by mass of calcium oxide, 15-20 parts by mass of boric ore; (2) mixing raw materials into a mixture; (3) melting the mixture to obtain glass metal; and (4) leading the glass metal into a centrifugal machine for fibration to obtain glass cotton. The method can ensure that the manufactured glass cotton meets the fireproof and flame-retardant requirements through strict control on raw materials. The method is adopted for production, the production cost can be lowered, and the energy resources can be saved.

The invention relates to an oil-water separation type emergency oil storage pool for a transformer of a 66kV substation. The oil-water separation type emergency oil storage pool is structurally characterized in that a baffle is arranged in the oil storage pool to divide the oil storage pool into an oil pool and a water pool, a water drain pipe and a water drain gate valve are installed between the oil pool and the water pool, and the oil pool and the water pool are respectively connected with an oil inlet pipe and a water outlet pipe. By adopting the oil-water separation type emergency oil storage pool, a good condition that the oil storage pool does not contain water throughout the year can be reached, the traditional methods of pumping the water by using a water pump and manually draining the water are abandoned and the labor intensity and the labor cost are reduced; and since the water is convenient to drain and the oil storage pool does not contain water in winter, the situation that the emergency oil storage pool is damaged due to water frost heaving is eliminated. Oil-water separation complies with requirements on safety, fire prevention and environmental protection, the economic benefit is great and thirty thousand Yuan can be saved every year. The operation reliability of the substation is improved and a reliable guarantee is provided for local industrial and agricultural production and household electricity use of people.

The invention discloses a fireproof door capable of blocking off a crack after meeting heat. The sealing device for blocking off the crack can resist fire for more than three hours and can be matched with the fire-resistant time of a fireproof steel frame; the edge of the door leaf or the door frame of the fireproof door is provided with a dovetail groove; a U-shaped sealing steel tank is arranged in the dovetail groove; the notch of the sealing steel tank faces to the bottom of the dovetail groove; a thermal expansion device is arranged in the inner cavity of the sealing steel tank; the edge of the door leaf or the door frame opposite to the orientation of the notch of the dovetail groove is provided with an elastomer collection tank; an elastic sealing adhesive tape is arranged in the elastomer collection tank; the middle of the outer side of the sealing steel tank is connected with an outward-bending elastic member; the elastic member is clamped on the inner side of the notch of the dovetail groove; in the normal use process, the elastic member is tightly embedded to seal the steel tank; the notch of the sealing steel tank is provided with an outward-bending bending part; when the sealing steel tank is outwards popped up, the bending part is clamped on the inner side of the notch of the dovetail groove.

The invention relates to the technical field of intelligence, in particular to an intelligent door lock handle clutch with a fireproof function. The clutch comprises a handle adapter assembly, a handle clutch assembly and a driving device; the handle adapter assembly is composed of an outer handle square shaft, a handle adapter shaft, a handle adapter sleeve and a check ring, the handle clutch assembly is composed of an inner handle, a large square shaft, a small square shaft, a square head adjusting screw, a fireproof linkage piece, a driving spring and a pushing spirng; through the handle adapter assembly, the door opening action of the outer handle is connected to the handle clutch in a door, the handle adapter shaft is of a blind hole structure, after locking, the handle outside the door idles, and the defect that an existing outer clutch and a lock body bolt moving shaft hole are exposed is overcome; the defects of safety and reliability existing in an existing intelligent lock external clutch can be effectively overcome, the problem that a clutch and an electronic device fail due to overtemperature, and unlocking cannot be achieved is solved, the structure is ingenious, practicability and reliability are achieved, and the safety and the reliability of the intelligent lock are improved.

An integrated branch smashing, storing and transporting vehicle comprises a storing and transporting vehicle body, a branch smashing device and a vehicle box used for loading branch chippings are arranged on a chassis of the storing and transporting vehicle body, and the branch smashing device is connected with the chassis through a fixing device. The branch smashing, storing and transporting vehicle integrates smashing, storing and transporting, one vehicle serves as one production line, an automatic operation system is adopted, and the branch smashing, storing and transporting vehicle has aprimary classification function and can automatically sort bark and leaves; the crushed branch chippings are directly stored in the carriage, so that the volume can be effectively reduced by 70%-90%;closed operation is adopted, so that flying dust and noise are avoided, the whole smashing process is green, low-carbon, environmentally friendly and free of worries; and branch stacking can be effectively reduced, the fireproof requirement is met, and potential safety hazards are reduced.

The invention relates to a fireproof lock for a ship. The fireproof lock for the ship comprises a lock cylinder, a spring bolt, a cam mechanism and a buckle. The cam mechanism comprises a rotating shaft, a stop block and a torsion spring.
