Description

Technical Field

[0001] The present invention relates to the field of power cabinets, and specifically to an intelligent DC power cabinet body structure. Background Art

[0002] An intelligent DC power cabinet is a current supply device used in a substation, mainly providing stable DC power supply for electrical equipment, such as high-voltage switch closing, signal control, and alarm circuits. The daily operation of an intelligent DC power cabinet requires a temperature range of -10°C to 40°C and a humidity of ≤85%. However, in some areas, it is difficult to ensure that the humidity is within this range, which is likely to cause internal corrosion, and then lead to the aging or even short circuit of electrical components.

[0003] Some existing relatively advanced intelligent DC power cabinets have an independent drying system to address the above situation. However, the desiccant inside these drying systems often automatically fails after being used for a period of time, resulting in a very short service life of the drying system. It often needs to be replaced every few months, which is very inconvenient and wastes desiccant. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent DC power cabinet body structure to solve the above problems.

[0005] The above technical objective of the present invention is achieved through the following technical solutions: An intelligent DC power cabinet body structure includes a cabinet body, and the cabinet body includes two side plates;

[0006] A humidity sensing component and a fan component are installed on the top of the cabinet body, and a drying component is installed at the bottom inside the cabinet body;

[0007] The drying component is composed of a storage component and a contact component. The storage component includes a storage barrel, a pressing plate is slidably arranged in the storage barrel, and the storage barrel is used to contain desiccant;

[0008] The contact component includes a contact barrel fixed between the side plates. The storage barrel is communicated with the contact barrel through a delivery pipe. A drying barrel is rotatably arranged in the contact barrel. A plurality of drying grooves are evenly opened on the outer side of the drying barrel. One of the drying grooves is aligned with the delivery pipe. The contact barrel is composed of two arc-shaped plates. The two arc-shaped plates form a drying port at the top and a discharge port at the bottom. The drying barrel is fixedly connected to the motor shaft of a motor, and the motor is fixed on the outer side of one of the side plates.

[0009] Preferably, a drying box is installed in each drying groove. A drying cavity is opened in the drying box, and the drying cavity is used to load desiccant. A number of first air-permeable holes are penetrated through both side walls of the drying cavity.

[0010] Preferably, an air-permeable strip is fixedly arranged in each of the drying cavities. An air vent cavity is formed in the air-permeable strip, and a plurality of second air-permeable holes are formed in three side walls of the air vent cavity.

[0011] Preferably, each drying box is slidably arranged in the drying groove. A slide bar is fixedly connected to the bottom of each drying box. The slide bar is slidably inserted into a slideway formed in the drying cylinder. A guiding bar is fixedly arranged at the end of each drying box. The guiding bars are all inserted into guiding grooves. Each guiding groove is composed of an arc and a protrusion. The guiding grooves are formed in a support plate, and the support plate is fixed to the side plate.

[0012] Preferably, a collection box fixed to the cabinet body is arranged at the bottom of the contact assembly.

[0013] Preferably, air-permeable holes are formed in the pressing plate. Threads are formed in the air-permeable holes. An air-permeable sheet is fixed to the bottom of the air-permeable holes. A plug is threadedly connected in the air-permeable holes. The material storage cylinder is fixed to the side plate through a bracket.

[0014] Preferably, the bottom of the drying cavity is inclined.

[0015] In summary, the present invention has the following beneficial effects:

[0016] 1. In the present application, a humidity sensing assembly is installed at the top of the cabinet body to monitor humidity. A fan assembly is also fixedly installed at the top of the cabinet body, and a drying assembly is installed at the bottom inside the cabinet body. When the humidity sensing assembly monitors that the humidity is too high, the fan assembly and the drying assembly are controlled to start through the built-in control system of the present application, so as to achieve the effect of intelligent dehumidification.

[0017] 2. The drying component consists of a storage component and a contact component. The storage component includes a storage cylinder, and a pressing plate is slidably arranged inside the storage cylinder. The contact component includes a contact cylinder fixed between the side plates. The storage cylinder is communicated with the contact cylinder through a conveying pipe. A drying cylinder is rotatably arranged inside the contact cylinder. A plurality of drying grooves are evenly formed on the outer side of the drying cylinder, and one of the drying grooves is aligned with the conveying pipe. The desiccant inside the storage cylinder will fall into this drying groove under the action of its own gravity. The contact cylinder is composed of two arc-shaped plates. The two arc-shaped plates form a drying opening at the top and a discharge opening at the bottom. The drying opening is directly opposite to the fan component. The drying cylinder is fixedly connected to the motor shaft of the motor. The motor is fixed on the outer side of one of the side plates. The motor drives the drying cylinder to rotate, driving the drying groove filled with desiccant to rotate to the position of the drying opening to dry the air blown out by the fan component. Another drying groove will be directly opposite to the conveying pipe to receive the desiccant. After the drying groove filled with desiccant moves to the position of the discharge opening, the internal desiccant will be discharged. Thus, it can achieve dehumidifying the interior only when the humidity exceeds the standard, which is very intelligent. Moreover, the desiccant can usually be in a relatively sealed state and will not get damp, greatly increasing its service life. In addition, the storage cylinder can hold a large amount of desiccant and does not need to be replaced frequently.

[0018] 3. A drying box is installed in each drying groove. A drying cavity is formed inside the drying box for loading desiccant. A number of first ventilation holes are penetrated through the two side walls of the drying cavity. After the air enters the drying cavity, it will be discharged through the first ventilation holes, greatly strengthening the air circulation effect, optimizing the contact effect between the desiccant and the air in the drying cavity, and greatly improving the drying speed.

[0019] 4. Each drying box is slidably arranged in the drying groove. A slide bar is fixedly connected to the bottom of each drying box. The slide bar is slidably inserted into a slideway formed on the drying cylinder. A guide bar is fixedly connected to the end of each drying box, and the guide bars are inserted into guide grooves. Each guide groove consists of an arc and a protrusion. The guide bar connected to the top drying box moves to the position of the protrusion of the guide groove, so as to extend out of the drying groove. The air entering the top drying box will no longer be blocked by the drying groove, greatly improving the utilization efficiency of the desiccant in the top drying box.

Specific embodiments

[0033] Combined with the attached Figures 1-11 The intelligent DC power cabinet body structure described above includes a cabinet body 11, and the cabinet body 11 includes two side plates 13;

[0034] All kinds of electronic components are installed in the cabinet body 11. Considering the situation of excessive humidity that may be encountered during use, the applicant installs a humidity sensing component 41 at the top of the cabinet body 11 to monitor humidity, and fixedly installs a fan component 42 at the top of the cabinet body 11. A drying component is installed at the bottom inside the cabinet body 11. When the humidity sensing component 41 detects excessive humidity, it will control the fan component 42 and the drying component to start through the built-in control system of the present application, so as to achieve the effect of intelligent dehumidification. The setting of the fan component 42 is to accelerate the air circulation inside the cabinet body 11 and achieve a faster dehumidification effect;

[0035] In the long-term use process, the applicant found that during the period when the conventional drying component does not dehumidify moisture, the desiccant inside it will also absorb water vapor and become ineffective after a short time, and needs to be replaced frequently.

[0036] Therefore, the applicant redesigned the drying component in the present application. The drying component of the present application is composed of a storage component 50 and a contact component 60. The storage component 50 includes a storage cylinder 16. A pressing plate 29 is slidably arranged in the storage cylinder 16. The storage cylinder 16 is used to contain desiccant. Generally, silica gel desiccant or activated carbon desiccant is used for the power cabinet. The pressing plate 29 and the storage cylinder 16 are kept sealed, so that the desiccant in the storage cylinder 16 will not be easily damp;

[0037] The contact component 60 includes a contact cylinder 15 fixed between the side plates 13. The storage cylinder 16 is communicated with the contact cylinder 15 through a delivery pipe 17. A drying cylinder 18 is rotatably arranged in the contact cylinder 15. A plurality of drying grooves 40 are evenly arranged on the outer side of the drying cylinder 18. One of the drying grooves 40 is aligned with the delivery pipe 17. The desiccant in the storage cylinder 16 will fall into the drying groove 40 under the action of its own gravity. The contact cylinder 15 is composed of two arc-shaped plates 36. The two arc-shaped plates 36 form a drying port 37 at the top and a discharge port 38 at the bottom. The drying port 37 is directly opposite to the fan component 42. The drying cylinder 18 is fixedly connected to the motor shaft of a motor 23. The motor 23 is fixed outside one of the side plates 13. The motor 23 drives the drying cylinder 18 to rotate, driving the drying groove 40 filled with desiccant to rotate to the position of the drying port 37 to dry the air blown out by the fan component 42. The other drying groove 40 will be directly opposite to the delivery pipe 17 to receive desiccant. After the drying groove 40 filled with desiccant moves to the position of the discharge port 38, the desiccant inside will be discharged. Thus, it can be realized that the desiccant is only used to dehumidify the inside when the humidity exceeds the standard, which is very intelligent. Moreover, the desiccant can usually be in a relatively sealed state and will not get damp, greatly increasing the service life. In addition, the storage cylinder 16 can hold a large amount of desiccant and does not need to be replaced frequently.

[0038] However, if the desiccant is only in the drying tank 40, the air circulation effect is not good after the air enters. Therefore, a drying box 25 is installed in each of the drying tanks 40. A drying cavity 19 is formed in the drying box 25, and the drying cavity 19 is used to load the desiccant. A number of first air-permeable holes 20 are formed through both side walls of the drying cavity 19. After the air enters the drying cavity 19, it will be discharged through the first air-permeable holes 20, greatly enhancing the air circulation effect, optimizing the contact effect between the desiccant and the air in the drying cavity 19, and greatly improving the drying speed.

[0039] However, the air circulation effect in the middle position of the drying cavity 19 is very poor again. Therefore, an air-permeable strip 21 is fixedly arranged in each of the drying cavities 19. An air ventilation cavity 34 is formed in the air-permeable strip 21, and a number of second air-permeable holes 22 are formed in three side walls of the air ventilation cavity 34. In this way, the air entering the drying cavity 19 will enter the air ventilation cavity 34 through the second air-permeable holes 22 at the top of the air-permeable strip 21, and is directly discharged into the desiccant in the drying cavity 19 through the second air-permeable holes 22 on both sides of the air ventilation cavity 34, thereby further improving the utilization effect of the desiccant in the middle position of the drying cavity 19.

[0040] In addition, when the drying box 25 is used inside the drying tank 40, it also affects the air circulation effect inside the drying box 25, resulting in low utilization rate of the desiccant. Therefore, each drying box 25 is slidably arranged in the drying tank 40. A slide bar 35 is fixedly connected to the bottom of each drying box 25, and the slide bar 35 is slidably inserted into a slide way 43 formed in the drying cylinder 18. A guiding bar 26 is fixedly connected to the end of each drying box 25, and the guiding bar 26 is inserted into a guiding groove 28 (which can slide and rotate, with only a limiting effect). The guiding groove 28 is composed of an arc and a protrusion. The guiding bar 26 connected to the top drying box 25 moves to the protrusion position of the guiding groove 28, so as to extend out of the drying tank 40. The air entering the top drying box 25 will no longer be blocked by the drying tank 40, greatly improving the use efficiency of the desiccant in the top drying box 25. The guiding groove 28 is formed in a support plate 27, and the support plate 27 is fixed to the side plate 13.

[0041] In addition, a collection box 24 fixed to the cabinet body 11 is arranged at the bottom of the contact assembly 60, and the collection box 24 is used to receive the desiccant discharged by the contact assembly 60.

[0042] Vent holes 31 are formed in the pressing plate 29. The vent holes 31 have internal threads. A vent sheet 33 is fixed at the bottom of the vent holes 31. A plug 32 is threadedly connected in the vent holes 31. The plug 32 seals with the vent holes 31. The pressing plate 29 can be taken out from the storage cylinder 16 for adding desiccant. When the pressing plate 29 is put back, the plug 32 needs to be manually unscrewed. The two sides of the vent holes 31 are communicated. When the pressing plate 29 is put in at this time, the air in the storage cylinder 16 will be discharged from the vent holes 31. After completion, the plug 32 is screwed on to maintain the seal. A handle 30 is fixed on the pressing plate 29 for easy handling. The storage cylinder 16 is fixed to the side plate 13 through a bracket 14.

[0043] It should be particularly noted that the holes in the vent sheet 33, as well as the sizes of the second vent holes 22 and the first vent holes 20, are all smaller than the size of the desiccant to prevent the desiccant from passing through.

[0044] To facilitate the distribution of the desiccant in the drying chamber 19, the bottom of the drying chamber 19 is designed to be inclined, with a higher position near the delivery pipe 17 and a lower position far from the delivery pipe 17, to ensure that the desiccant in the drying chamber 19 can smoothly cover the entire drying chamber 19 under the action of gravity.

[0045] Usage method: When the humidity sensing component 41 detects that the humidity is too high, it will control the fan component 42 and the drying component to start through the built-in control system of the present application. The motor 23 drives the drying cylinder 18 to rotate, driving the drying trough 40 filled with desiccant to rotate to the drying port 37 position to dry the air blown out by the fan component 42. During the rotation, the guiding strip 26 connected to the top drying box 25 moves to the protruding position of the guiding groove 28, so as to extend out of the drying trough 40. The air entering the top drying box 25 will no longer be blocked by the drying trough 40. Another drying trough 40 will face the 39 to receive desiccant. After the drying trough 40 filled with desiccant moves to the discharge port 38 position, the internal desiccant will be discharged into the collection box 24.

[0046] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention, and their purpose is to enable those skilled in the art to understand the content of the present invention and implement it, and cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
