Description

Technical Field

[0001] The present invention relates to the technical field of key management, and in particular to an intelligent key management box for a transformer substation. Background Art

[0002] Substations are an important part of the power system. One of their main functions is to transform voltage. In power plants, electric energy usually needs to increase its voltage through step-up substations so that it can be transmitted over long distances more efficiently. When the electric energy reaches the vicinity of the user, it needs to be reduced by step-down substations to meet the needs of different users. At the same time, substations are also responsible for receiving and distributing electric energy. They connect power grids of various voltage levels through their transformers to ensure that electric energy can be transmitted from power plants to user terminals. Therefore, substations play a vital role in power systems. They can not only transform voltage, receive and distribute electric energy, but also control the flow of electricity, adjust voltage, improve energy utilization efficiency, promote economic development, promote sustainable development, ensure the reliability of power system operation, and help reduce construction and operating costs.

[0003] At present, in order to facilitate different operation and maintenance personnel to use substation keys, special key boxes are equipped in substations to store keys of various electric control cabinets, distribution boxes and operating tables. However, the existing key boxes are not only troublesome when borrowing and returning keys, but also have no good records of borrowed keys, which is not conducive to the statistics of substation keys and inconvenient for operation and maintenance personnel to manage substation keys. Therefore, we propose a substation intelligent key management box. Summary of the invention

[0007] Preferably, the storage device includes a key seat, a plurality of identification plates are installed on the upper end of the key seat, a plurality of storage slots are opened on the upper end of the key seat, a plurality of the storage slots are installed with card columns, a plurality of the storage slots are opened at the lower ends with through holes, a plurality of mounting racks are installed on the lower end of the key seat, a plurality of the mounting racks are installed on the upper ends of the plurality of the mounting racks, a plurality of the infrared reflection sensors correspond to a plurality of through holes in upper and lower positions, a plurality of the infrared reflection sensors are electrically connected to the controller, and the key seat is fixedly mounted on the lower inner wall of the key box. Since the infrared transmitter built into the infrared reflection sensor generates an infrared beam after being powered on, the transmitter emits infrared light. When the light encounters an object and is reflected back, the receiver detects the reflected light and outputs a signal sensor. The existence of the object is detected by utilizing the principle of reflection of the infrared beam encountering an obstacle. Therefore, the infrared light emitted by the infrared reflection sensor at the lower end of the corresponding storage slot is derived from the through hole. Therefore, after the key is taken out, it can be detected by the infrared reflection sensor. The controller is electrically connected to the infrared reflection sensor, thereby detecting the removal of the key, and recording the time of lending and returning the key, which is convenient for recording and management of the key box.

[0008] Preferably, the closing device includes a motor, two of which are provided, a connecting shaft is fixedly installed at the output ends of the two motors, a group of locking frames are fixedly installed at the upper ends of the two connecting shafts, and a gasket is fixedly installed at the lower ends of the two groups of locking frames, and two fixing grooves are opened at the left end of the support plate, and the two motors are fixedly installed in the two fixing grooves respectively, and the two motors are electrically connected to the controller.

[0009] Preferably, the front end of the controller is equipped with several connectors, the rear upper end of the controller is equipped with a display screen, the upper left end of the display is equipped with a keypad, and the upper right end of the controller is equipped with a fingerprint recognition area. The staff can use the keypad on the controller to unlock the key with a password or the fingerprint recognition area to unlock the key, so that the key box can be opened through the controller to take out or return the key.

[0010] Preferably, the lighting device comprises a No. 1 LED lamp holder and a No. 2 LED lamp holder, and LED lamp beads are installed at one end of the No. 1 LED lamp holder and the No. 2 LED lamp holder, respectively fixedly mounted on the front inner wall and the rear inner wall of the key box, and the No. 1 LED lamp holder and the No. 2 LED lamp holder are electrically connected to the controller.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When it is necessary to borrow the key in the key box to enter the substation for operation, the staff can first use the key area on the controller to unlock the password or the fingerprint recognition area to unlock the fingerprint. At this time, the controller starts the electric push rod on the fixing device, and the electric push rod drives the piston rod at its output end to retract. At this time, the staff can open the box cover to expose the key inside the key box, and then continue to start the motor on the closing device through the controller. The motor drives the connecting shaft on it to rotate backward, so that the locking frame on the connecting shaft opens. At this time, the staff can directly take out the key from the corresponding storage slot, and when the key is taken out, due to The infrared transmitter built into the infrared reflection sensor generates an infrared beam after being powered on. The transmitter emits infrared light. When the light encounters an object and is reflected back, the receiver detects the reflected light and outputs a signal sensor. The existence of the object is detected by utilizing the principle of reflection of the infrared light beam encountering an obstacle. Therefore, the infrared light emitted by the infrared reflection sensor at the lower end of the corresponding storage slot is derived from the through hole. Therefore, after the key is taken out, it can be detected by the infrared reflection sensor. The controller is electrically connected to the infrared reflection sensor to detect the removal of the key, thereby recording the time of lending and returning the key, which is convenient for recording and management of the key box and improves the practicality of the device.
