The application provides a box-type transformer substation and power transmission equipment, and belongs to the technical field of power equipment. The box-type transformer substation comprises a box body and a ventilation window. The box body is provided with a window. The ventilation window comprises a plurality of blades arranged at intervals from top to bottom in the window. Each blade can rotate around its own axis. Any two adjacent blades have a ventilation state with a flow gap therebetween and a heat preservation state in which the two blades are lapped to seal the box body. In the heat preservation state, any two adjacent blades are lapped to each other and form a closed heat preservation chamber. The application forms a closed heat preservation chamber by lapping the blades, uses the static air layer in the chamber to achieve efficient heat insulation, guarantees the ventilation and heat dissipation demand in a high-temperature environment, provides reliable heat preservation effect in a low-temperature environment, and is beneficial to improving the environmental adaptability of the box-type transformer substation under severe working conditions.

The utility model belongs to the field of doors and windows, particularly relates to a door and window with heat insulation and heat preservation functions, and aims to solve the problems that indoor temperature is difficult to keep comfortable and stable under extreme weather conditions and living environment quality is affected due to the fact that an existing door and window cannot effectively block indoor and outdoor heat transfer, the following scheme is provided: the door and window comprises a window outer frame, a window inner frame and glass, the inner window frame is hinged to the outer window frame through hinges, the inner window frame is located on the inner ring of the outer window frame, and the three pieces of glass are arranged on the inner ring of the inner window frame; and the heat insulation and preservation assembly is arranged in the window inner frame and used for shielding the glass. Through the arrangement of the heat insulation and preservation assembly, the heat insulation and preservation performance of the door and window is effectively improved, indoor and outdoor heat transfer can be blocked when the weather is hot or cold, the indoor temperature is kept comfortable and stable, and meanwhile operation is easy and convenient, and use is convenient and fast.

This utility model relates to the field of heat-insulating bearing sleeve technology, specifically a heat-insulating bearing sleeve for a turbocharger, including a bearing sleeve body in the shape of a ring. A heat-insulating layer made of ceramic fiber is installed on one side of the inner wall of the bearing sleeve body. This utility model effectively blocks the large amount of heat generated during turbocharger operation from being transferred to the bearing sleeve through the ceramic fiber heat-insulating layer on the inner wall, preventing damage to bearings and other components due to high temperatures. The nickel-based alloy transition layer between the heat-insulating layer and the bearing sleeve body enhances the bonding strength between the two, ensuring that the heat-insulating layer is not easily detached under long-term high-temperature conditions. Simultaneously, the annular heat dissipation fins on the outer wall of the bearing sleeve body increase the contact area with air, accelerating heat dissipation, and several pressure relief holes can promptly release internal pressure caused by temperature changes, further improving the stability of the bearing sleeve under high-temperature conditions.

The invention discloses a high-strength flame-retardant phenolic aldehyde fireproof thermal insulation integrated board and a preparation method thereof, and belongs to the technical field of building materials. Phenolic resin, modified expanded vermiculite, polyphenyl particles, graphite polyphenyl particles, perlite particles and hexamethylenetetramine are mixed and stirred to obtain a mixture, and the mixture is subjected to hot press molding to obtain a structural layer phenolic board; taking a phenolic aldehyde insulation board as a middle layer, sequentially laying non-woven fabric on the surface of one side of the core material, smearing bonding mortar, attaching a structural layer phenolic aldehyde board, laying alkali-resistant glass fiber mesh cloth, smearing anti-crack mortar, and standing for 15 minutes; laying a non-woven fabric on the other side of the core material according to the same process, coating the non-woven fabric with adhesive mortar, attaching a second structural layer phenolic aldehyde plate, laying an alkali-resistant fiberglass mesh, and coating anti-crack mortar to obtain a prefabricated integrated plate; and standing and curing the prefabricated integrated plate to obtain the integrated plate. The obtained integrated plate has good mechanical property, flame retardant effect and heat preservation performance, and meets the requirement for integration of fire prevention and heat preservation of buildings.

This utility model relates to the field of ceramic fiber heat-resistant board technology, and more particularly to an environmentally friendly ceramic fiber heat-resistant board, comprising a fiber matrix layer, a ceramic fiber board, a reinforcing layer, a ceramic fiber felt, and a surface coating. The fiber matrix layer includes an intermediate layer, with an upper surface layer and a lower surface layer fixedly connected to the upper and lower surfaces of the intermediate layer, respectively. The reinforcing layer, ceramic fiber felt, and ceramic fiber board are sequentially fixedly connected to the upper and lower ends of the fiber matrix layer. The surface coating is applied to the surface of the ceramic fiber board. The reinforcing layer includes a surrounding panel, with mortises on all four inner walls of the surrounding panel, into which tenons are engaged. Transverse reinforcing rods are fixedly connected between corresponding tenons on the left and right sides of the surrounding panel, and longitudinal reinforcing rods are fixedly connected between corresponding tenons on the front and rear sides of the surrounding panel. The unique design of the reinforcing layer of this utility model greatly enhances the overall strength of the board, reduces the risk of deformation and damage, improves the toughness of the board, and effectively blocks heat transfer, meeting the environmental protection requirements of modern society.
