Description

Technical Field

[0001] The invention belongs to the technical field of transformer substation protection equipment, and in particular relates to an induction type rodent-proofing device and a use method thereof. Background Art

[0002] In the power system, substations are the core hub for power conversion and distribution, and the stable operation of their internal equipment is crucial. In order to protect the equipment from external interference, especially to prevent small animals such as mice from entering the equipment room and causing short circuits or malfunctions, substations generally install rodent-proof baffles at the entrances of each equipment room. This measure effectively builds a physical barrier and reduces the risk of equipment failure.

[0003] However, with the increasing demand for refined and efficient operation and maintenance of substations, the existing rodent-proof baffle design has gradually exposed some problems. First, in high-frequency operation scenarios such as daily inspections of substations, complex switching operations, emergency abnormality handling, and heavy equipment handling, workers need to frequently cross these rodent-proof baffles, which not only increases physical exertion, but also significantly prolongs the task execution time, posing a direct challenge to operation and maintenance efficiency.

[0004] In addition, from the perspective of safety emergency management, a rapid response accident emergency mechanism must be established within the station to ensure that personnel can evacuate to a safe area quickly and without obstacles in an emergency. Although the rodent-proof baffle effectively blocks small animals, it may become an obstacle on the escape route during emergency evacuation, limiting the path for personnel to evacuate quickly, which invisibly reduces precious escape time and increases the severity of the consequences of the accident. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention provides an induction-type rodent-proofing device and a method of using the same to solve the above-mentioned technical problems.

[0007] A further improvement of the technical solution is that the support rod adopts an optical axis, each optical axis is slidably connected to a connecting block, all the connecting blocks are on the same vertical line, and are fixedly connected to the protective baffle.

[0008] A further improvement of the technical solution is that the driving structure includes a motor mounting bracket and a DC motor, the motor mounting bracket is installed at one end of the support frame close to the door of the equipment room, and the DC motor is vertically installed on the motor mounting bracket.

[0009] A further improvement of the technical solution is that the transmission structure includes a wire rope, a wire rope fixer, a take-up roller, a first transmission wheel and a second transmission wheel, the take-up roller is installed above the motor mounting bracket, the take-up roller is connected to the output end of the DC motor, the first transmission wheel is installed on the support frame on one side of the take-up roller, the second transmission wheel is installed on the end of the support frame away from the door of the equipment room, the wire rope fixer is installed on the end of the take-up roller away from the motor mounting bracket, the wire rope is wound around the take-up roller, one end of the wire rope is fixed to the wire rope fixer, and the other end of the wire rope is connected to the end of the connecting block away from the door of the equipment room through the first transmission wheel and the second transmission wheel.

[0010] A further improvement of the technical solution is that the sensing module includes a microwave sensor and a smoke sensor, both of which are installed on the protective baffle, and both of which are connected to the input end of the main control module.

[0011] A further improvement of the technical solution is to use a human body microwave sensor with model ZT-WBXDT485-1.

[0012] A further improvement of the technical solution is that the drive structure also includes two emergency drive components, both of which are installed at one end of the support frame close to the door of the equipment room, one is installed on the inner side above the support frame, and the other is installed on the inner side below the support frame.

[0013] A further improvement of the technical solution is that the emergency drive assembly includes a compression spring, a spring limit block and a hydraulic cylinder, one end of the compression spring is fixed to one end of the support frame close to the equipment room door, the other end of the compression spring is in contact with the spring limit block, an installation groove is provided on the support frame, the hydraulic cylinder is installed in the installation groove, the output end of the hydraulic cylinder is connected to the spring limit block, the micro hydraulic cylinder drives the spring limit block to extend out to resist the compression spring, the micro hydraulic cylinder also drives the spring limit block into the installation groove, releasing the compression spring to apply force to the connecting block, driving the protective baffle to translate closer to the support frame, and the elastic force of the compression spring is greater than the elastic force of the reset spring.

[0016] The beneficial effects of the present invention are: Improve operation and maintenance efficiency: By integrating the sensing module and the control module, the device can intelligently identify the approach of personnel in the substation and automatically adjust the opening state of the protective baffle. In high-frequency operation scenarios such as daily inspections, switching operations, abnormal handling, and heavy equipment handling, there is no need for manual frequent crossing of the protective baffle, which significantly reduces the physical exertion of the staff and shortens the task execution time, thereby greatly improving the operation and maintenance efficiency.

[0017] Enhanced safety emergency response capabilities: In emergency situations, such as fires, earthquakes and other emergencies, the sensing module can respond quickly and automatically remove the blocking state of the protective baffle to provide an unobstructed passage for personnel evacuation.
