At present, the electric control cabinet has multiple drawer boxes installed on its own cabinet body through guide rails. The drawer box is used as a cavity to install electrical components, circuits and other components. This results in the need for staff to manually pull out the drawer boxes one by one during maintenance work, which causes inconvenience in operation during maintenance, especially when the cabinet body is high, and staff are required to repeatedly operate up and down, which increases the complexity and time-consuming of the operation. In addition, the manual operation of the drawer box increases the frequency of use of mechanical parts, which is easy to cause failure of the drawer box itself. For example, the drawer track, handle and other components may be worn or damaged during long-term use, thereby affecting the normal operation of the drawer box. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-7 The utility model provides an embodiment: an electric control cabinet with intelligent control drawers that automatically open and close, comprising an electric control cabinet body 1 and a plurality of support frames 3 fixed at equal intervals inside the electric control cabinet body 1, a heat dissipation hole 101 is fixed at the bottom end of the electric control cabinet body 1, and bases 6 are provided at both ends of the surface of the electric control cabinet body 1;

[0021] Drawer box monomers 2 are installed on both sides of the top of the support frame 3 through two sliding guide structures 4, and handles 12 are installed on both sides of the surface of the drawer box monomers 2. A linear rack 7 is fixed inside the support frame 3 between two adjacent sliding guide structures 4, and a gear drive unit 14 is installed on one side of the bottom of the drawer box monomer 2. The gear drive unit 14 is used to drive the drawer box monomer 2 to move along the extension direction of the linear rack 7;

[0022] A box body position sensing unit 5 is arranged inside the support frame 3 below the drawer box monomer 2. A control knob 8, a pull-out button 9 and a push-in button 10 are sequentially installed on one side of the surface of the drawer box monomer 2 from left to right. The control knob 8 includes a manual position and an automatic position. The manual position of the control knob 8 is usually used when the gear drive unit 14 fails and the drawer box monomer 2 needs to be pulled out to repair the gear drive unit 14.

[0023] A disconnect knob handle 13 is installed on the surface of the drawer box monomer 2 above the push button 10, and an indicator light 11 is installed on the other side of the surface of the drawer box monomer 2. The output ends of the pull-out button 9 and the push-in button 10 are electrically connected to the input end of the gear drive unit 14, and the input ends of the control knob 8, the indicator light 11, and the disconnect knob handle 13 are electrically connected to the output end of the electric control cabinet body 1;

[0024] The sliding guide structure 4 is composed of a lower guide rail 401 and an upper guide sleeve 402. The lower guide rail 401 is fixed to one side of the top of the support frame 3, and the upper guide sleeve 402 is fixed to one side of the bottom end of the drawer box monomer 2 and slides with the lower guide rail 401.

[0025] The support frame 3 is connected and fixed to the electric control cabinet body 1, and the interval height between the two adjacent support frames 3 is determined by the height specification of the drawer box monomer 2. When the drawer box monomer 2 slides, the sliding stability of the drawer box monomer 2 is improved by the lower guide rail 401 and the upper guide sleeve 402, and the integral lower guide rail 401 and the upper guide sleeve 402 are more evenly stressed than the slider or pulley drawer box, and there is no jamming phenomenon in the process of pulling out and pushing in the drawer box monomer 2;

[0026] The lower guide rail 401 and the upper guide sleeve 402 are both made of wear-resistant high-molecular polyethylene material. The high-molecular polyethylene has wear-resistant properties and also has a certain degree of self-lubrication, which reduces the friction between the guide rail and the guide groove during the process of pulling out or pushing in the drawer box, so that the drawer box will not be stuck during the process of pulling out or pushing in.

[0027] The gear drive unit 14 includes a servo motor 1401 installed on one side of the bottom of the drawer box monomer 2, and a motor fixing plate 1402 installed on the top of the servo motor 1401. The output end of the motor fixing plate 1402 is installed with a driving gear 1403, and the driving gear 1403 is meshed with the linear rack 7. When the gear drive unit 14 receives the working signal of the extraction button 9 or the push button 10, the motor fixing plate 1402 actively drives the driving gear 1403 to rotate, and the driving gear 1403 drives itself and the servo motor 1401, the drawer box monomer 2 and other components to move along the extension direction of the linear rack 7, so as to realize the extraction and storage functions of the drawer box monomer 2;

[0028] The box position sensing unit 5 includes two right-angle limit frames 501 fixed to the right side of the longitudinal beam of the support frame 3, and a limit sensor 502 installed on one side of the bottom end of the drawer box monomer 2. The box position sensing unit 5 is arranged inside the support frame 3 under each drawer box monomer 2, wherein the limit sensor 502 is installed at the bottom of the box body of the drawer box monomer 2, so that the limit sensor 502 can sensitively sense the right-angle limit frame 501, and the right-angle limit frame 501 at the front and rear positions can feedback whether the drawer box monomer 2 is pulled out or pushed in, so as to avoid the drawer box being pulled out too far or not pushed in enough;

[0029] When the drawer box monomer 2 is automatically pulled out and the limit sensor 502 senses the right-angle limit frame 501 on the outside, the gear drive unit 14 stops working. At this time, the upper guide sleeve 402 of the drawer box monomer 2 and the lower guide rail 401 still overlap by a certain length to ensure that the drawer box monomer 2 will not derail.

[0030] When the embodiment of the present application is in use, first, after the electric control cabinet body 1 and the drawer box monomer 2 are installed as a whole, the drawer box monomer 2 is pushed into place during normal operation, and the control knob 8 is in the automatic position, and then the drawer box monomer 2 is under the automatic control of the gear drive unit 14, and the electrical components or circuits in the corresponding drawer box monomer 2 fail, the indicator light 11 starts to flash an alarm, and at the same time, the fault information is fed back to the central control room of the power station and related maintenance personnel, and then the circuit breaker knob handle 13 is automatically rotated to the disconnected position, and finally, with the cooperation of the gear drive unit 14 and the linear rack 7, the failed drawer box monomer 2 is automatically pushed out for the maintenance personnel to repair the fault point. After the repair is completed The maintenance personnel only needs to press the push button 10, and the gear drive unit 14 receives the working signal and cooperates with the linear rack 7 to automatically push the drawer box monomer 2 into the electric control cabinet body 1. After being pushed into place, the circuit breaker knob handle 13 is automatically rotated to the closed position, so that the drawer box monomer 2 of the electric control cabinet body 1 can realize the automatic push-out or retract function. If the maintenance is performed under non-fault conditions, the maintenance personnel only needs to press the withdrawal button 9 or the push button 10, and the gear drive unit 14 automatically pulls out or pushes in the drawer box monomer 2 according to the control signal, reducing the work of the maintenance personnel. The electric withdrawal and push-in functions can avoid the situation where the drawer box monomer 2 is not pushed into place or the circuit breaker knob handle 13 is not rotated to the closed position.
