6results about How to "Improve pressure relief efficiency" patented technology

The utility model relates to the technical field of positive-voltage power distribution cabinets, and discloses a positive-voltage power distribution cabinet with explosion-proof and pressure-relief functions, which comprises a cabinet body, a cabinet door is rotatably connected to one side in the cabinet body, a pressure-relief assembly is arranged at the top of the cabinet body and comprises a pressure-relief top window, and fixing plates are arranged on two sides of the bottom of the pressure-relief top window. And guide grooves are formed in the two fixing plates correspondingly, supporting plates are fixedly connected to the two sides of the bottom of the pressure relief transom window correspondingly, connecting plates are fixedly connected to the bottoms of the two supporting plates correspondingly, and sliding rods are fixedly connected to one sides of the outer walls of the two connecting plates correspondingly. According to the utility model, the pressure relief transom window is jacked upwards by impact force, so that the displacement of the connecting plate is converted into rotation under the linkage of the connecting arm I and the connecting arm II and the limitation of the guide groove, the pressure relief transom window is rotated from horizontal to vertical, the top of the cabinet body is completely opened, and the effect of quick explosion-proof pressure relief is achieved; the problems that a traditional cabinet body is slow in pressure relief, concentrated in impact and prone to damage are solved, and the pressure relief efficiency is improved.

The utility model discloses a guide support, lithium cell and electrical equipment belong to lithium cell technical field, guide support is used to install in the inside of battery casing, including support body, the support body includes first support surface and second support surface who sets up oppositely, first support surface is used for supporting the electric core, and the second support surface sets up towards the battery casing inner wall who installs explosion -proof valve, first support surface of support body is provided with main guide groove and secondary guide groove, and secondary guide groove communicates with main guide groove, and main guide groove corresponds with the explosion -proof valve trepanning position, and secondary guide groove extends away from the explosion -proof valve trepanning position. The main guide groove and secondary guide groove of the utility model guide the electrolyte to the position away from the explosion -proof valve trepanning, avoid the electrolyte too much gathering at the explosion -proof valve trepanning position, alleviate the pressure of explosion -proof valve trepanning position pressure relief, reduce the fire risk.

This invention provides a battery casing and a battery. The battery casing is rectangular, and at least one side of the battery casing is provided with an explosion-proof groove structure. The explosion-proof groove structure includes a rectangular explosion-proof outer frame, which includes a first explosion-proof groove, a second explosion-proof groove, a third explosion-proof groove, and a fourth explosion-proof groove connected end to end in sequence. A fifth explosion-proof groove and a sixth explosion-proof groove are provided inside the rectangular explosion-proof outer frame. One end of the fifth explosion-proof groove and one end of the sixth explosion-proof groove intersect, and the connection point of the fifth explosion-proof groove and the sixth explosion-proof groove is located on one of the first, second, third, and fourth explosion-proof grooves. The other three of the first, second, third, and fourth explosion-proof grooves have two connection endpoints. The other end of the fifth explosion-proof groove is located at one of the connection endpoints, and the other end of the sixth explosion-proof groove is located at the other connection endpoint. The battery casing of this embodiment has the characteristic of high pressure relief efficiency.

This invention belongs to the field of textile technology, specifically a down-collecting device and processing method for down processing. It includes a down-filling hopper, an adjusting unit at one end of which contains a down-washing unit, and a pressure-relief unit within the down-washing unit. The invention uses an electric telescopic rod to move a filter plate inside the down-filling hopper away from the three-phase motor until the down inside the hopper is compressed to a designated area on one end of the electronic scale. Simultaneously, a crank connecting rod rotates, and a pressure-relief plate, under the control of a panel, rotates at a certain angle within the filter plate. This allows for real-time control of the alignment between the filter holes in the pressure-relief plate and the mesh of the filter plate. During this process, a pressure-relief valve extracts gas from inside the down-filling hopper to the outside, ensuring a vacuum in the down-retention area, eliminating the influence of air buoyancy, reducing airflow interference, effectively avoiding static electricity, improving the accuracy of the electronic scale's weight measurement, and ultimately improving product quality control precision.

This utility model provides an explosion-proof oil-immersed current transformer, belonging to the field of current transformers. It includes a transformer body, with an oil conservator at the top and an expander above the conservator, equipped with a top pressure relief component. Below the conservator is a porcelain bushing, and below the bushing, from top to bottom, are a riser and an oil tank. A bottom pressure relief component is located on the side of the oil tank. The beneficial effect of this utility model is that, based on existing oil-immersed current transformers, it not only retains the top pressure relief component at the expander but also adds an additional bottom pressure relief component at the oil tank. This allows for rapid pressure relief and explosion-proof protection when the internal pressure of the transformer body increases sharply, through the coordinated operation of the two pressure relief components.
