The present invention relates to the technical field of building walls, and discloses a pressure relief explosion-proof wall structure, including an embedded box embedded in the wall, an outer sealing plate is rotatably provided on the left side plate of the embedded box, and a slide plate is slidably provided on the right side plate, an inner sealing plate corresponding to the outer sealing plate is rotatably provided on the slide plate, and a connecting rod is rotatably connected between the outer sealing plate and the inner sealing plate; an extension plate is integrally provided at the end of the slide plate, and a limit plate is elastically slidably inserted on the embedded box. The present invention can achieve a pressure relief effect to reduce the probability of damage to the wall and the effect of personal injury, and can also keep the outer sealing plate and the inner sealing plate in an open state when there is no explosion risk and ventilation is required, so as to achieve indoor ventilation and play the role of a ventilation window, thereby eliminating the setting of the ventilation window in the prior art, reducing the number of reserved installation openings in the wall, and enhancing the strength of the wall.

The invention discloses a composite rotor cooling mechanism of a permanent magnet synchronous traction motor. A rotor core of the mechanism is provided with a skewed pole structure and is provided with a magnetic isolation groove, permanent magnets are uniformly arranged on the peripheral surface of the rotor core at intervals along the circumferential direction, a sheath is sleeved on the permanent magnets and the rotor core and is provided with a magnetic isolation groove, and wind thorns are arranged on the end surface of the air inlet side of the composite rotor cooling mechanism and are positioned at the magnetic isolation groove. In a limited cooling space, the magnetic isolation grooves parallel to the skewed poles are arranged, and the wind thorns are additionally arranged on the air inlet sides of the magnetic isolation grooves, so that the convective heat transfer coefficient in the magnetic isolation grooves is improved, the effect of cooling the motor is better achieved, the loss of the motor is reduced through the skewed poles of the rotor and the magnetic isolation grooves, and the temperature rise of the motor is reduced from the source. The magnetic isolation grooves, the skewed poles and the inner hole are used in a matched mode, starting from the two aspects of reducing loss and improving the heat dissipation coefficient, compared with a single cooling structure, the cooling mechanism has a better effect on reducing temperature rise, and the cooling mechanism can be applied to a more complex motor.

This utility model discloses a novel corrugated structure vibration film packaging device, belonging to the technical field of packaging devices. It includes a placement plate and a top cover positioned above the placement plate. The top of the placement plate has multiple placement holes arranged in a rectangular array, and the bottom of the placement plate has multiple placement frames arranged in a rectangular array, located below the placement holes on the same side. A fixing component is provided between the top cover and the placement plate, and a reinforcing plate is provided at the top of the top cover. This utility model, through the cooperation of the top cover, placement plate, and placement frames, can effectively package vibration film. The reinforcing plate at the top of the top cover and the baffle at the bottom of the placement plate increase the strength of the top cover and placement plate. Furthermore, the support block at the top of the placement plate supports the inner wall of the top of the top cover, which helps to increase the stress point of the top cover, reduce the deformation of the top cover under external forces, and improve the protective effect of the product on the vibration film.

The invention discloses a deicing device and application thereof, the deicing device comprises a vibration assembly and a driving assembly, the vibration assembly comprises a first eccentric block and a second eccentric block, and a driving part is connected with a first rotating shaft and a second rotating shaft through a steering part to drive the first rotating shaft and the second rotating shaft to coaxially and reversely rotate. Meanwhile, the first eccentric block is connected with the second rotating shaft, and the second rotating shaft drives the first eccentric block to rotate around the axial center of the second rotating shaft. The second eccentric block is connected with the first rotating shaft which drives the second eccentric block to rotate around the axial center of the first rotating shaft. As the first rotating shaft and the second rotating shaft coaxially and reversely rotate, the first eccentric block and the second eccentric block are respectively driven to coaxially and reversely rotate. The first eccentric block and the second eccentric block drive the deicing device to vibrate in the reverse rotation process, so that the overhead transmission line coated with ice vibrates at the same time, ice blocks or frost layers are shaken off, and efficient deicing is achieved.
