An internal temperature detection system for a box-type power distribution cabinet

Abstract

The present invention relates to the field of distribution cabinets, and specifically relates to an internal temperature detection system for a box-type distribution cabinet. When the detection module detects that the temperature between two certain accommodation cavities is too high, the wire winding roller will lower the originally isolated heat exchange plate, so that the heat exchange plate enters the storage cavity. Another set of wire winding rollers winds up, stretching the spare heat exchange plate in the storage cavity. The heat exchange plate entering the storage cavity is cooled. At the same time, after the spare storage cavity is stretched, the heat exchange holes are opposite to the cooling holes, and the cooling fan blows cold air into the heat exchange holes, thereby cooling the entire heat exchange unit. It can detect and cool the partition between the row of distribution cabinets in an environment relatively closed to the outside, and avoid external dust from entering the interior of the distribution cabinet while cooling.

Description

Technical Field

[0001] The present invention relates to the technical field of distribution cabinets, and in particular to an internal temperature detection system for a box-type distribution cabinet. Background Art

[0002] A box-type distribution cabinet is a common power equipment, which also includes a combined distribution cabinet. The main purpose is to install multiple box-type distribution cabinets in a row to save installation space. However, there is a problem of inconvenient heat dissipation for the row-mounted distribution cabinets. Specifically, when the temperature of one distribution cabinet is too high, its temperature will be transmitted into its adjacent distribution cabinet through the side wall of the distribution cabinet connected to it. And because the adjacent side wall has little contact with the external air, it is difficult to dissipate heat. The Chinese patent application with the application number CN202010620821.0 discloses a monitoring distribution cabinet with automatic detection and alarm and its heat dissipation method, which can perform heat dissipation operations on individual distribution cabinets, and can also stack all the sliding plates at one time to open all the distribution cabinets to complete the heat dissipation operations of all the distribution cabinets. The implementation method is simple and occupies little space.

[0003] However, the applicant has found that the prior art has at least the following problems:

[0004] When dissipating heat, it is necessary to open the back of the distribution cabinet for heat dissipation, which easily causes dust to enter and affects the performance of the distribution cabinet. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an internal temperature detection system for a box-type distribution cabinet to solve the problem that when dissipating heat, it is necessary to open the back of the distribution cabinet for heat dissipation, which easily causes dust to enter and affects the performance of the distribution cabinet.

[0009] A heat exchange module: receives the signal from the signal processing unit and is used to replace and cool the adjacent inner walls of each row of housing units;

[0010] The signal processing unit receives the temperature value sent by the detection module and compares it with the preset temperature stored in the signal processing unit.

[0041] In some alternative specific embodiments, such as Figures 1-5 As shown, the housing unit includes: a housing 101, in which a plurality of partition inner walls 105 are installed, and the plurality of partition inner walls 105 partition the interior of the housing 101 into a plurality of accommodation cavities 102.

[0042] In some alternative specific embodiments, the heat insulation unit includes mounting grooves 201 formed on the inner walls of the accommodation cavities 102. The mounting grooves 201 are arranged on both sides of the partition inner walls 105. A plurality of heat exchange plates 301 are adaptively installed in the mounting grooves 201. The plurality of heat exchange plates 301 are hinged by a hinge assembly 302. A heat exchange cavity 303 is provided inside the plurality of heat exchange plates 301. The plurality of heat exchange cavities 303 are connected by a hose 304. A heat exchange hole 305 is formed at the bottom of the lowermost heat exchange cavity 303, and the heat exchange hole 305 allows external air to enter. When in use, a plurality of heat exchange plates 301 are respectively installed on both sides of the partition inner walls 105. The plurality of heat exchange plates 301 are connected by a hose 304. The external cold air enters the heat exchange cavity 303 from the heat exchange hole 305 and is transmitted through the hose 304.

[0043] In some alternative specific embodiments, the power unit includes a housing 202 installed on the top of the protection module. A drive shaft 203 is installed in the housing 202. A wire winding roller 204 is installed on the drive shaft 203. A wire 205 is wound around the wire winding roller 204. The wire 205 is fixedly connected to the top of the heat exchange plate 301. A storage cavity 103 is provided at the bottom of the accommodation cavity 102. When the wire winding roller 204 pays out the wire, the plurality of heat exchange plates 301 enter the storage cavity 103. When it is detected that the temperature between two certain accommodation cavities 102 is too high, the wire winding roller 204 lowers the originally separated heat exchange plates 301 so that the heat exchange plates 301 enter the storage cavity 103, and another wire winding roller 204 winds up the wire to stretch the spare heat exchange plates 301 in the storage cavity 103.

When in use, the cooling fan 108 blows cold air into the heat exchange hole 305, thereby cooling the entire heat exchange unit.

[0046] In some optional specific embodiments, the hinge assembly 302 includes a connection seat 306 mounted on one set of heat exchange plates 301.

The mounting seat 307 is fixedly connected to a mounting plate 308, and the mounting plate 308 is fixedly connected to the other set of heat exchange plates 301.

[0047] Working principle of the present invention: When the detection module detects that the temperature between two certain accommodation cavities 102 is too high, the wire take-up roller 204 lowers the originally separated heat exchange plates 301, so that the heat exchange plates 301 enter the storage cavity 103. Another wire take-up roller 204 winds up, stretching the spare heat exchange plates 301 in the storage cavity 103. The heat exchange plates 301 entering the storage cavity 103 are cooled. At the same time, after the spare storage cavity 103 is stretched, the heat exchange holes 305 are opposite to the cooling holes 107, and cold air is blown into the heat exchange holes 305 through the cooling fan 108, thereby cooling the entire heat exchange unit. It can detect and cool the partition between row-mounted power distribution cabinets in an environment relatively closed to the outside, and avoid external dust from entering the interior of the power distribution cabinet while cooling.
