Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinet auxiliary technology, in particular to a novel drawer of a drawer-type switch cabinet. Background Art

[0002] Low-voltage drawer-type power distribution cabinet (hereinafter referred to as low-voltage drawer cabinet) is a commonly used electrical control device. In addition to directly controlling the input working power of electrical equipment, the low-voltage drawer cabinet also outputs control signal instructions to the electrical equipment, and the electrical equipment is in different working conditions under the control signal instructions. Existing power distribution cabinets generally include a cabinet body and multiple control drawers. The control drawers can be pulled out and pushed in through the drawer slide rails of the cabinet body. The rear end of each control drawer has one or more power input and output terminals (which are plugged and connected to one or more power output and input terminals at the rear end of the low-voltage drawer cabinet), and one or more signal input and output terminals (which are plugged and connected to one or more signal output and input terminals at the rear end of the low-voltage drawer cabinet).

[0003] The authorized patent of my country's patent number "201922330520X" and patent name "Low Voltage Drawer Cabinet" records that "the utility model can cool down and dissipate heat inside the low voltage cabinet when the drawer assembly in the low voltage cabinet is pulled out for maintenance, with good heat dissipation effect, effectively preventing the aging of the line due to excessive temperature, and reducing safety hazards". As can be seen from the above, although the patent has achieved the invention purpose of preventing the aging of the line due to excessive temperature and reducing safety hazards, it is limited by the structure like other drawer-type switch cabinets and still has the following technical disadvantages. Specifically, the drawer slide rail is plugged together by the plug-in parts at the rear end and the plug-in parts at the rear end of the cabinet, so when the staff opens and closes the drawer, they often have to use a large force to plug the plug-in parts together or separate them. This will bring inconvenience to the staff and increase the labor intensity of the staff. In addition, when the electrical components in the drawer are on fire due to various reasons, the drawer cannot be opened immediately, and there is a probability that the plug-in parts will be burned together and cannot be effectively opened, which is not conducive to timely handling of the fire and will lead to the expansion of the accident. Utility Model Content

[0004] The utility model provides a drawer that allows staff to open it not only manually but also electrically, thus bringing convenience to the staff and achieving a better operating experience. The drawer can also be automatically opened forward when a fire occurs inside the drawer due to various reasons, thus preventing the connectors from being burned together due to the drawer being opened too late as much as possible, making it more conducive to handling fires and reducing the chance of accidents expanding. The utility model effectively overcomes the drawer of the prior art that has the disadvantages as described in the background due to structural limitations and provides a new type of drawer-type switch cabinet.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0015] Figure 4 This is a circuit diagram of the utility model. DETAILED DESCRIPTION

[0016] Figure 1 , 2 As shown in , 3 and 4, a new type of drawer-type switch cabinet drawer includes a drawer body 4, a power supply module D1, a battery G1 (12V, 1Ah), a trigger mechanism 1 and an opening and closing mechanism, and a power switch K1; the power supply module D1, the battery G1, the trigger mechanism 1 and the opening and closing mechanism are respectively provided in multiple sets, and the trigger mechanism 1 is respectively installed in multiple drawer bodies 4 of the drawer-type switch cabinet 3 through a component box 2; the opening and closing mechanism includes two electric push rods MD, and a set of linear slide rails 6 are respectively installed longitudinally on both sides of the upper end of the drawer partition 5 at the lower end of each drawer body 4 of the low-voltage drawer cabinet body through bolts, and the lower ends of the shells of the two electric push rods MD are respectively installed longitudinally on the sliding blocks 61 of the two sets of linear slide rails through bolts, and a limit plate 62 is vertically welded on the rear side end of the shell of each set of linear slide rails 6; the front ends of the push columns of the two electric push rods MD and the middle of both sides of the outer lower end of the drawer body 4 are respectively Welded together; each set of power supply module D1, power switch K1, battery G1 and trigger mechanism 1 are installed at the front end (inside the component box) of each drawer body 4, and the handle of the power switch K1 is located outside the first opening on the outside of the front partition of the drawer body 4. The power input ports 1 and 2 of the power supply module D1 and the AC 220V power connector in the drawer body are connected by wires respectively. The power output ports 3 and 4 of the power supply module D1 and the power input ports 1 and 2 of the power switch K1, the power input end of the trigger mechanism, the two control power input ends of the relay JK, and the power input ends of the battery G1 are connected by wires respectively. The power output ports 3, 4, 5, 6 of the power switch K1 and the positive and negative and negative and positive power input ends of the electric push rod MD are connected by wires respectively. The two normally open contact ends of the relay JK and the negative and positive power input ends of the electric push rod MD are connected by wires respectively. 8 is a drawer slide rail that is slidably installed and controls the movement of the drawer body.

[0017] Figure 1 , 2As shown in , 3, and 4, the linear slide 6 is a non-powered linear slide. The height of the limit plate 62 is slightly lower than the height of the lower end of the electric push rod MD housing, and higher than the upper end of the sliding block 61 of the linear slide. The trigger mechanism includes a temperature detection module D2 (the temperature probe is located outside the rear end opening of the component box, which is conducive to detecting the temperature change in the drawer body) and a relay JK, and a power switch AK2 connected by circuit board wiring. The handle of the power switch AK2 is located outside the second opening on the outer side of the front partition of the drawer body. The positive power input port 1 of the temperature detection module D2 is connected to one end of the power switch AK2, and the other end of the power switch AK2 is connected to the first control power input terminal of the relay JK. The negative power input terminal and the second control power input terminal of the relay JK are connected to the negative power input port 2 of the temperature detection module D2, and the power output port 3 of the temperature detection module D2 is connected to the positive power input terminal of the relay JK. The temperature detection module D2 can also be replaced by a smoke detection module.

[0018] Figure 1 , 2 As shown in Figures 3 and 4, normally, after the power supply module D1 is powered, its ports 3 and 4 output DC power to charge the battery G1 (all mechanisms can work normally after power failure). At the same time, the power switches K1, K2 and the trigger mechanism are powered and work. In normal times, the staff of this new type can directly pull the drawer body 4 forward to open or backward to close through the handle at the front end of each drawer body 4, and can also open or close the drawer body 4 through the power switch through the electric push rod, which brings convenience to the staff and a better experience. Specifically, the staff pulls the drawer body 4 forward to open or backward to close through the handle 7 at the front end of each drawer body 4, and the drawer body 4 moves forward or backward along the sliding block 61 of the linear slide rail through the outer shell of the electric push rod MD, so that the staff can manually control the drawer body 4 to open or close. The staff turns the handle of the power switch K1 to the left or right respectively, and the ports 1, 2 and ports 3, 4 or ports 5, 6 of the power switch K1 are connected respectively, and then the positive and negative or negative and positive power input terminals of the two sets of electric push rods MD are energized; the push columns of the two sets of electric push rods MD push the drawer body 4 backward or forward, and turn off the power switch after they are in place, so that the staff can open or close the drawer body 4 without manual force (the rear end of the shell of the electric push rod is in contact with the front end of the limit plate 5, which prevents the sliding block from moving backward in the opposite direction when the subsequent electric push rod pushes the drawer body 4 forward, causing the drawer body 4 to fail to move forward effectively).

[0019] Figure 1 , 2As shown in Figure 3, when there is no fire in the drawer and the temperature is appropriate (for example, below 50°C), the 3rd port of the temperature detection module D2 will not output power, the relay JK will not be energized and attracted, and the electric push rod will not push the drawer body 4 to the front end. When a fire occurs in the drawer body 4 due to various reasons and the internal temperature rises (for example, above 50°C), the 3rd port of the temperature detection module D2 will output power to the power input end of the relay JK, and the relay JK will be energized to attract its two control power input ends and two normally open contact ends to close, and then the negative and positive power input ends of the two sets of electric push rods MD are energized, and the push columns of the two sets of electric push rods MD push the drawer body 4 forward to open, which prevents the drawer body 4 from being opened too late in the event of a fire, causing the connectors to burn together, which is more conducive to handling the fire and reducing the probability of the accident expanding (eliminating the fault, turning off the power switch K2 before operating the power switch K1 each time). Figure 4 Among them, the power supply module D1 is an AC 220V to DC 12V power supply module; the electric push rod MD is a reciprocating electric telescopic rod, and the front and rear ends of its shell are equipped with limit switches. When the push column moves forward or backward to the stop point, the electric push rod will automatically lose power (without preventing the reverse input power from being powered); the working voltage of the relay JK is DC 12V; the temperature detection module D2 is a temperature detection switch of model YYW-2, which can detect temperatures between 0~1000°C, and can control the upper and lower limits of the temperature through its own buttons, so that the matching relay can operate to output power (output power after reaching the set temperature).
