The utility model provides a kind of auxiliary concentrator device for box station, including substrate, multiple spaced concentrator racks are provided side by side on the front side of substrate, and the concentrator rack includes plug-in section, winding section, limiting section and extension section, winding section is horizontally arranged, plug-in section and limiting section are located at both ends of winding section and vertically arranged, and plug-in section is plugged in the front side of substrate, limiting section is vertically provided with telescopic extension section at both ends, the utility model has the beneficial effects: the device effectively stores the cable that is too long in box station, avoids cable too long, too much and causes confusion, affects the disassembly and overhaul of equipment in box station.

This utility model discloses a raft-type liftable aerator, relating to the field of aerator technology. The utility model includes plastic floats, elbows, tees, connectors, aeration risers, an aerator body, and steel wire ropes. Two floats are provided, and several elbows are provided, with the two floats connected by the elbows. By using two floats connected by several elbows and then joined by the connector to form a raft, the stability of the aerator body is increased. Four steel wire ropes are used to fix the entire raft, adding two more steel wire ropes than the single float of the original suspended chain aeration system, further reducing the swaying amplitude of the floats on the water surface. By replacing the hose (snake-skin hose) connection between the floats and the aerator body with a connector that connects to the aerator body via the aeration riser (which is a rigid pipe), tangling of the hose (snake-skin hose) is avoided, preventing tangling from affecting the equipment's performance and maintenance.

The utility model discloses an automatic organ preserving fluid adding and transferring device, which relates to the technical field of living tissue transportation and comprises a storage cylinder, a cylinder cover is movably mounted on the outer side of the storage cylinder close to the upper side, and the upper side of the cylinder cover is fixedly connected with a fluid storage bin. Handles are fixedly connected to the positions, close to the upper side, of the left side and the right side of the storage barrel, the inner side of the storage barrel is movably sleeved with a placement mechanism, and a liquid injection mechanism is rotationally connected to the upper side of the placement mechanism. According to the automatic organ preserving fluid adding and transferring device, through pulling of the tension spring, the pressing plate is used for fastening the tank cover, the injection pipe is pushed through the electric push rod, the pressing net is made to move up and down, the height of the pressing net can be adjusted, small biological tissue is prevented from shaking at will when transported in the inner tank, and the working efficiency is improved. Meanwhile, when the whole bottom plate is placed, the tank cover is still in a fixed state, and the living tissue is prevented from spilling out.

The utility model relates to the technical field of electric vehicles, in particular to an electric vehicle motor protection device which comprises a motor protection cover, mounting holes for mounting the motor protection cover are annularly formed in the motor protection cover at equal intervals, screws are arranged at the mounting holes, and a first ring groove and a second ring groove are formed in the motor protection cover. A protection assembly is arranged on the motor protection cover; after the motor protection cover is fixedly mounted, rubber ring pads are embedded in a first ring groove and a second ring groove, and then a protection ring is positioned and mounted, so that a first embedded ring is inserted into the first ring groove, a second embedded ring is inserted into the second ring groove, and the protection ring is matched to cover a screw so as to protect the screw for fixing the motor protection cover; abrasion and corrosion of the screw in the using process are avoided, and electric vehicle motor maintenance is prevented from being affected.

This utility model discloses an electrical ventilation device for transformers used in electrical engineering, relating to the field of transformer electrical ventilation technology. It includes a housing box, inside which a transformer body is installed. Heat dissipation slots are equidistantly spaced on both sides of the inner wall of the housing box. An ventilation mechanism is provided inside the housing box, comprising two cleaning components and an auxiliary heat dissipation component. The cleaning components and the auxiliary heat dissipation component work together. The cleaning components include a cleaning motor, which is fixedly connected to the outside of the housing box. A fixing plate is fixedly connected in a rectangular array to one side of the inner wall of the housing box. This utility model discloses an electrical ventilation device for transformers used in electrical engineering. Through the ventilation mechanism, the inner wall of the heat dissipation slots can be quickly cleaned, preventing dust from adhering to the inner wall of the heat dissipation slots. It drives a cleaning brush to remove dust from the heat dissipation slots, ensuring smooth ventilation. The device has a simple structure and strong practicality.
