Description

Technical Field

[0001] The invention belongs to the technical field of electrical control cabinets, and in particular relates to a multifunctional integrated electrical control cabinet for garbage power generation. Background Art

[0002] The electrical control cabinet is a device for centralized control and protection of electrical equipment. In terms of basic structure, the cabinet is made of cold-rolled steel plate, with a surface sprayed with plastic to prevent rust, and a thickness of 1.2-2.0mm, which provides protection and shielding for internal components. The mounting plate is made of metal and fixed inside the cabinet. The electrical components are installed through standardized mounting holes. There are meters, buttons and indicator lights on the door to facilitate operation and obtain equipment status; the internal components have various functions. The circuit breaker automatically cuts off the circuit when the circuit is overloaded or short-circuited to protect the equipment. The contactor is used to control the start and stop of high-power equipment. The relay controls the large current with a small current to achieve signal conversion, amplification and logic control. The fuse will melt when the current rises abnormally, cutting off the circuit.

[0003] There are many electrical components in the electrical control cabinet, and the heat generated needs to be dissipated in time to help the normal operation of the electrical control cabinet. The existing electrical control cabinet mainly relies on external air conditioning for heat dissipation. However, this heat dissipation method has little effect on the heat discharge in the electrical control cabinet. For this reason, the prior art will add a heat dissipation component to the door panel of the electrical control cabinet, and generally dissipate heat through water cooling. However, this heat dissipation method cannot be changed according to the load size. If the temperature difference between the inside and outside of the cabinet is too large, it will also cause condensation of the air with moisture in the cabinet, affecting the normal use of the electrical cabinet. For this reason, we propose a multifunctional integrated electrical control cabinet for waste power generation to solve the above problems. Summary of the invention

On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0032] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention pertains. The terms used herein are intended only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] Examples, such as Figure 1-8 As shown, a multifunctional integrated electrical control cabinet for waste power generation includes a control cabinet body 10 and a heat dissipation door panel 20 movably mounted on the front side of the control cabinet body 10. Figure 1 As shown, the control cabinet body 10 includes a control cabinet housing 101 and heat dissipation openings 102 opened on both sides of the control cabinet housing 101;

[0035] like Figure 2-4As shown, the heat dissipation door panel 20 includes a door panel body 201, a heat dissipation assembly 30 is also installed in the door panel body 201, and multiple groups of heat dissipation holes 202 are symmetrically opened at the upper and lower parts of the door panel body 201, so as to facilitate the entry of cold air when the temperature inside the control cabinet is too high. Normally, there is no need to open the heat dissipation holes 202, so a sliding plate 210 is also slidably arranged on the inner wall of the door panel body 201, and holes corresponding to the heat dissipation holes 202 are also opened on the sliding plate 210. When the holes on the sliding plate 210 are aligned with the heat dissipation holes 202, the heat dissipation holes 202 are opened. When aligned, air can enter the electrical control cabinet from the heat dissipation holes 202. Sliding rails 203 are also arranged along both sides of the sliding plate 210. The sliding rails 203 are fixedly arranged on the inner wall of the door panel body 201. The sliding plate 210 can move up and down along the sliding rails 203. There are two groups of sliding plates 210. Cylinders 204 are also arranged along the opposite ends of the two groups of sliding plates 210. The telescopic shaft of the cylinder 204 is fixedly connected to the end of the sliding plate 210 to drive the sliding plate 210 to move.

[0036] like Figure 2 as well as Figure 5 As shown, the heat dissipation assembly 30 includes a movable plate 301 and a fixed plate 302. A cooling pipe 303 is provided between the movable plate 301 and the fixed plate 302. The cooling pipe 303 is in contact with the movable plate 301. The movable plate 301 is also provided with a cooling pipe 303 toward the inside of the cabinet. Figure 8 The heat sink 304 shown is in a stacked form under normal conditions, and the heat in the cabinet contacts the heat sink 304, and then the heat is taken out through the cooling pipe 303 to dissipate heat in the cabinet;

[0037] In addition, the heat dissipation component 30 also includes a second form, which can increase the heat dissipation efficiency to cope with the heat dissipation work in the overload situation, as shown in the following example: Figure 3 as well as Figure 6 As shown, a bracket 205 is fixedly installed on the inner wall of the door panel body 201, and a plurality of plate bodies are extended from the bracket 205 toward the door panel body 201, and a lead screw 206 is installed on the plate body, and a nut seat 207 is movably arranged on the outer side of the lead screw 206, and a first connecting frame 208 and a second connecting frame 209 are fixedly installed on the upper ends of the nut seats 207, wherein the first connecting frame 208 is also fixedly connected to the uppermost heat sink 304, and a plurality of groups of heat sinks 304 are provided, and a hinge is provided between two adjacent groups of heat sinks 304, so that the two groups of heat sinks 304 are hinged to each other, and when overloaded, the lead screw 206 is driven to rotate, so that the nut seat 207 drives the first connecting frame 208 to move along Figure 8 Move in the direction A shown, so that the stacked heat sink 304 is unfolded to expand the area in contact with heat;

[0038] At the same time, if Figure 4 , Figure 5 as well as Figure 7 As shown, a protruding block 308 is further provided on the front end surface of the movable plate 301, and guide columns 306 are further fixedly installed at the four corners of the fixed plate 302. A guide groove is further provided along the guide column 306 of the movable plate 301. The guide column 306 passes through the guide groove, and the exposed guide column 306 is fixedly screwed with a hexagonal nut. A return spring 307 is further provided on the outer side of the guide column 306. The return spring 307 can prop the movable plate 301 forward. When the nut seat 207 moves along the A direction, the second connecting frame 209 fixed with the nut seat 207 moves along the A direction, as shown in FIG. Figure 2 As shown, the second connecting frame 209 presses the protruding block 308 on the movable plate 301 toward the fixed plate 302, and an extrusion groove 305 is provided on the opposite end surfaces of the fixed plate 302 and the movable plate 301. The extrusion groove 305 is in the shape of a flat tube, and the cooling tube 303 can be extruded to make the cooling tube 303 change from a round tube to a flat tube. The flat tube is easier to dissipate heat because the shape of the flat tube can enhance convective heat transfer, and more fully exchange heat with the air outside the radiator (i.e., the movable plate 301 and the heat sink 304 in the text), thereby improving the heat dissipation efficiency. The selected cooling tube 303 is a plastic hose, which can be deformed into a flat tube when there is external force extrusion, and can elastically return to a round tube when there is no external force extrusion;

[0039] Among them, Fig. 9 As shown, the multifunctional integrated electrical control cabinet for waste power generation also includes a temperature control sensor, which is used to measure temperature, and an MCU module, wherein the temperature control sensor and the MCU module are electrically connected, and the MCU module controls the cylinder 204 and the motor driving the lead screw 206. When the temperature in the cabinet exceeds the threshold set by the temperature control sensor, the signal is transmitted to the MCU module, and the MCU module is used to control the up and down movement of the output shaft of the cylinder 204 and the forward and reverse rotation of the output shaft of the lead screw 206 motor. The method of controlling electrical components by using temperature control sensors and MCU modules belongs to the prior art and is therefore not described in detail in this article.

[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-mentioned embodiments only express several embodiments of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
