The surface wiping device for the watch touch screen comprises a bottom plate, a supporting plate, a top plate and telescopic rods, the supporting plate is fixedly connected to the left side and the right side of the top of the bottom plate, the top plate is fixedly connected to the top of the supporting plate, and the telescopic rods are arranged on the left side and the right side of the top of the top plate. A quick release assembly is arranged at the bottom of the top plate, sliding rails are fixedly connected to the front side and the rear side of the top of the bottom plate, sliding sleeves are slidably connected to the tops of the sliding rails, and connecting plates are fixedly connected to the tops of the inner sides of the sliding sleeves. By arranging the fixing plate, the wiping head can be rapidly replaced by the fixing plate, and the problems that in the using process, due to the fact that the wiping head is not provided with an auxiliary replacing structure, when the wiping head needs to be replaced due to abrasion or smudginess, time and labor are wasted, the number of times of production interruption is obviously increased, and the production efficiency is improved are solved. And therefore, the device has the advantage of assisting in replacement.

The invention relates to the technical field of oil cylinders, and discloses a 90-degree rotary connecting rod mechanism oil cylinder which structurally comprises a cylinder body, a cavity and a driving chamber are arranged in the cylinder body, the cavity and the driving chamber are communicated through a communicating hole, a piston rod is arranged in the cavity, the other end of the piston rod movably penetrates through the communicating hole and extends into the driving chamber, and the driving chamber is arranged in the cavity. The cavity is rectangular, a piston piece is installed in the cavity in a matched mode, an open groove is formed in the middle of the piston piece, and a first sealing piece and a second sealing piece are installed in the open groove. The first sealing piece and the second sealing piece make contact with the inner wall of the cavity, so that the phenomenon that the piston piece and the cavity cannot be sealed due to abrasion of the first sealing piece and the second sealing piece is avoided, and the replacement frequency of the first sealing piece and the second sealing piece is reduced; the service life of the first sealing piece and the second sealing piece is prolonged, and the sealing effect of the oil cylinder in the using process is improved.

The utility model belongs to the technical field of distribution box, concretely relates to a kind of overhaul power supply box intelligent control power transmission device, including total power supply control box and several overhaul power supply boxes, and the incoming line end inside total power supply control box is provided with power supply total air switch, and the input end of each overhaul power supply box is respectively connected to the output end of power supply total air switch by branch air switch, and multiple feeder circuits are provided in each overhaul power supply box, and the outgoing line end of each feeder circuit is correspondingly connected with one power socket for inserting temporary power plug during overhaul, and the leakage protection switch with leakage and overload protection function is respectively arranged on each feeder circuit, and the control contactor that can be remotely controlled to attract / close is connected with secondary line control circuit.The device can realize remote power transmission and timing power-off of overhaul power supply box through mobile phone APP, which can effectively reduce the trouble and safety risk caused by frequent connection and disconnection of temporary power line in overhaul work and stop power transmission operation.

The embodiment of the invention discloses a dry-type transformer device which comprises a dry-type transformer body and a static contact unit, the dry-type transformer body is provided with a moving contact unit corresponding to the static contact unit, the static contact unit comprises a plurality of static contact mechanisms, and the moving contact unit comprises a moving contact mechanism. The moving contact mechanism comprises a bus current-conducting plate, a contact support frame and two duckbilled moving contacts, the two duckbilled moving contacts are oppositely arranged on the bus current-conducting plate, and pressure springs for clamping the two duckbilled moving contacts are arranged between the duckbilled moving contacts and the contact support frame; the static contact mechanism comprises a duckbilled static contact used for being inserted between the two duckbilled moving contacts of the moving contact mechanism. According to the invention, the dry-type transformer can be quickly separated from a power supply end and a load end and can be quickly moved to a safe position so as to facilitate maintenance, so that the safety of maintenance personnel is ensured essentially, and quick power transmission can be realized by only replacing the dry-type transformer without repairing the dry-type transformer when a fault occurs.

The present invention relates to a free oscillation type power transformer rapid demagnetization circuit. The free oscillation type power transformer rapid demagnetization circuit comprises a status indication module, a switching power supply module, a capacitor bank module, a control module, and a working indication circuit; the status indication module, the switching power supply module, the capacitor bank module, the control module, and the working indication circuit are connected in sequence. The free oscillation type power transformer rapid demagnetization circuit is a high-efficiency demagnetization circuit for power transformers, which is designed to efficiently and quickly complete the demagnetization of power transformers to prevent equipment failures caused by the misoperation of transformer protection caused by the huge excitation surge current when the transformer is transmitting power, delaying power transmission, thereby causing power system accidents, which have a great impact on people's lives and property, traffic safety, production and life.
