[0033] The use method and advantages of the utility model: When the electronic clock which can be adjusted at multiple angles is used, the working process is as follows:
[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, first, the mounting base 1 is fixed to the surface of the control console of the substation through the through hole at the bottom thereof through the external fixing parts. In daily use, the clock body 7 (model CS-HTT) can provide accurate time and is equipped with corresponding temperature and humidity sensors, which can simultaneously monitor the ambient temperature in the control room, and help operators understand the working environment in the control room. The servo motor of the device is electrically connected to a controller (model TAD-YK618), which is equipped with a wireless remote control switch. In daily work, operators can carry the wireless remote control switch. When it is necessary to record the time, the wireless remote control switch can be used to drive the servo motor to rotate the worm 2 to drive the semi-worm gear 3, so that the chassis 4 drives the clock body 7 on the surface to rotate horizontally 180° along the surface of the mounting base 1, providing operators with a wider field of view without being limited by the limitation of fixed angles. At the same time, when the surface of the clock body 7 is affected by the reflective light, the structure can also ensure that the information is displayed more clearly by adjusting the direction of the clock body 7, which is crucial to ensure that operators can accurately read the information displayed by the clock. When the clock body 7 is not enabled or needs to be cleaned, it can be controlled by the drive group The servo motor on one side of the component 5 rotates the driving gear 501, and then the half gear 502 rotates. The driving gear 501 and the half gear 502 on the other side of the coaxially connected lower chassis 4 rotate respectively, so that the base 503 rotates with the rotation of the half gear 502, so that the clock body 7 is turned 90 degrees into the chassis 4. When the clock body 7 is turned over, the sponge tube 805 can be retracted in the chassis 4 through the external spring 803 structure to maintain the appropriate height of contact with the surface of the clock body 7, and can automatically adjust the height according to the height of the surface of the clock body 7 under the elastic structure to maintain the contact with the clock body. The sponge tube 805 is cleaned when the sponge tube 805 needs to be cleaned later, the plug-in rod 804 is squeezed toward the right tenon groove 802 to disengage the other end of the plug-in rod 804 from the left tenon groove 801. When the clock body 7 fails, the side plate 604 is pushed and pulled outward to open the distance between it and the card-connecting end 602 to provide a space for easy operation for taking out the clock body 7. At the same time, a card slot is provided on one side of the chassis 4 for placing files recording relevant data.
