Description

Technical Field

[0001] This invention relates to the field of intelligent energy-saving control cabinets, and in particular to an intelligent energy-saving control cabinet for both heating and cooling. Background Technology

[0002] Electrical control cabinets can display various operating parameters using measuring instruments and adjust certain electrical parameters; they can also provide alerts or issue signals when the operation deviates from normal operating conditions. During normal operation, circuits can be connected or disconnected using manual or automatic switches. In case of faults or abnormal operation, circuits can be cut off or alarms can be triggered using protective electrical devices. They are commonly used in various power generation, distribution, and substations.

[0003] Chinese Patent No. CN112367790A discloses a photovoltaic energy-saving electrical control cabinet, belonging to the technical field of electrical control cabinets. This control cabinet has photovoltaic panels electrically connected to a battery on both sides of a triangular top cover at the top of the cabinet. These panels convert light energy into electrical energy and store it, providing emergency lighting during emergency repairs and powering independent equipment within the cabinet. Furthermore, a storage cavity is provided at the top of the cabinet. Inside this cavity is a removable protective cover, and inside the anti-slip cover are two side covers that can be pulled out and unfolded to be located on either side of the anti-slip cover. These side covers provide rain protection for electrical maintenance personnel during circuit repairs, facilitating repairs and enhancing maintenance safety.

[0004] As can be seen from the above structure, the existing dual-purpose (heating and cooling) intelligent energy-saving control cabinet has a key defect in outdoor photovoltaic power supply scenarios. The photovoltaic panels integrated on the top surface lack a snow accumulation handling mechanism. After snowfall in winter, snow easily accumulates and covers the surface of the photovoltaic panels, not only blocking sunlight and preventing the photovoltaic panels from effectively receiving sunlight, significantly reducing the photoelectric conversion efficiency or even completely interrupting power generation, but also increasing the load on the photovoltaic panel installation structure due to the weight of the snow accumulation, which may cause panel deformation and loosening of wiring terminals. At the same time, the ice water produced by melting snow can easily seep into the wiring points or the inside of the control cabinet along the edges of the photovoltaic panels, causing faults such as short circuits and corrosion, further damaging the photovoltaic power supply circuit. In low-temperature environments, the melted ice water freezes and forms an ice layer, which can also scratch the surface coating of the photovoltaic panels, damaging the photoelectric conversion performance in the long term, causing the photovoltaic power supply system to fail continuously, seriously affecting the energy supply stability of the dual-purpose (heating and cooling) function of the control cabinet, and making it difficult to meet the continuous use needs of outdoor scenarios that rely on photovoltaic power supply. Summary of the Invention

[0005] The purpose of this invention is to provide a dual-purpose (heating and cooling) intelligent energy-saving control cabinet to solve the problem of poor cleaning effect mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a dual-purpose (heating and cooling) intelligent energy-saving control cabinet, comprising a mounting base, a cabinet body fixedly connected to the upper end of the mounting base, a cabinet top fixedly connected to the upper end of the cabinet body, a center plate fixedly connected to the upper end of the cabinet top, top covers rotatably connected to both sides of the center plate, photovoltaic panels provided on the outer surface of the top covers, cleaning components provided on the outer surface of the top covers, a support component fixedly connected to the outer side of the cabinet top, the cleaning component comprising a mounting plate disposed on the upper end of the top cover, a mounting rod fixedly connected to one side of the mounting plate, a cleaning groove provided on the inner side of the mounting rod, a cleaning screw rotatably connected to the inside of each cleaning groove, a threaded component threaded to the outer surface of each cleaning screw, a snow scraper fixedly connected to the inner side of each threaded component, a synchronous pulley fixedly connected to the other end of each cleaning screw, the synchronous pulley being connected via a synchronous belt drive, a synchronous motor fixedly connected to the other side of the mounting plate, and the output shaft of the synchronous motor being fixedly connected to the synchronous pulley.

[0007] Furthermore, the support assembly includes a support base fixedly connected to the outer side of the cabinet top. The surface of the support base is provided with a support groove. A bidirectional screw is rotatably connected inside the support groove. Movable parts are threadedly connected to both sides of the outer surface of the bidirectional screw. A connecting rod is fixedly connected to the upper end of each movable part. A support motor is fixedly connected to the outer side of the support base. The output shaft of the support motor is fixedly connected to the bidirectional screw.

[0008] Furthermore, the other end of the connecting rod is slidably connected to the lower end of the top cover, the upper end of the connecting rod is provided with an installation groove, and a support pulley is rotatably connected inside the installation groove. The lower end of the top cover is provided with a support sliding groove, and the support sliding groove and the support pulley are slidably connected to each other.

[0009] Furthermore, the inner side of the connecting rod is slidably connected to the outer side of the cabinet top, and a limiting groove is provided on the inner side of the connecting rod. A limiting slide block is fixedly connected to the outer side of the cabinet top, and the limiting slide block and the limiting groove are slidably connected to each other.

[0010] Furthermore, both sides of the outer surface of the limiting slide are provided with hidden grooves, and the interior of each hidden groove is provided with a fixing through hole. A fixing screw is inserted into the interior of each fixing through hole, and the limiting slide is threadedly connected to the top of the cabinet by the fixing screw.

[0011] Furthermore, rubber scrapers are fixedly connected to both sides of the snow scraper, and the lower end of the rubber scraper is slidably connected to the surface of the photovoltaic panel. The rubber scraper is fixedly connected to the snow scraper by connecting screws.

[0012] Furthermore, support rods are fixedly connected to both sides of the upper end of the center plate, and a protective plate is fixedly connected to the upper end of the support rods. The protective plate is located directly above the mounting plate.

[0013] Furthermore, protective nets are fixedly connected to both sides of the upper surface of the cabinet top, covering the upper surface of the cabinet top, and the lower end of the top cover is movably connected to the outer surface of the protective net.

[0014] Furthermore, a drive shaft is rotatably connected to the inner side of the cabinet top, and a drive plate is fixedly connected to the outer surface of the drive shaft. Multiple drive plates are provided, and the drive plates are located at the center of the cabinet top.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] Firstly, in this invention, the synchronous motor is started, and its output shaft drives the synchronous pulley fixed to it to rotate. Through the synchronous belt drive, the synchronous pulleys of the cleaning screws on both sides rotate synchronously, thereby driving the cleaning screws in the cleaning groove to rotate. The threaded part, through the threaded engagement with the cleaning screw, converts the rotational motion into linear motion, driving the inner snow scraper to move back and forth along the cleaning groove on the surface of the photovoltaic panel on the top cover, realizing the removal and cleaning of accumulated snow. The synchronous motor and synchronous belt drive ensure that the cleaning screws on both sides operate synchronously, the snow scraper is evenly stressed and moves smoothly, avoiding cleaning deviation due to unilateral stress. The reciprocating movement of the snow scraper can fully cover the surface of the photovoltaic panel, cleaning without dead corners, ensuring the photovoltaic panel's light reception efficiency, maintaining stable photovoltaic power supply, and eliminating the need for manual cleaning. It is especially suitable for harsh environments such as high altitude and extreme cold, reducing operation and maintenance costs and safety risks. During the cleaning process, the snow scraper makes flexible contact with the photovoltaic panel, and with the smoothness of the screw drive, it can efficiently remove snow while avoiding damage to the photovoltaic panel coating, extending the service life of the equipment, and ensuring a continuous and reliable energy supply for the control cabinet's dual-function heating and cooling function.

[0017] Secondly, in this invention, the starting support motor drives the bidirectional screw in the support groove to rotate. The moving parts on both sides of the outer surface of the bidirectional screw move synchronously in opposite directions through threaded engagement, driving the upper connecting rod to move synchronously. The support pulley at the upper end of the connecting rod slides along the support groove at the lower end of the top cover, guiding the top cover to rotate around the central plate to achieve adjustment of the opening and closing angle. By adjusting the opening and closing angle of the top cover, the ventilation gap between the top cover and the top of the cabinet can be increased when the internal temperature of the control cabinet rises, forming a natural ventilation channel, accelerating the exhaust of hot air from the cabinet and the inflow of cold air from the outside, improving heat dissipation efficiency. Auxiliary ventilation can be achieved without opening the main heat dissipation structure of the cabinet, reducing energy consumption, which is in line with the design concept of energy-saving control cabinets. At the same time, the size of the ventilation gap can be flexibly adjusted according to the heat generation in the cabinet, avoiding excessive ventilation that would cause the internal temperature of the cabinet to drop too low, affecting the stability of the dual-use function of heating and cooling. This ensures that electrical components operate at a suitable temperature, reduces the loss of frequent start-stop of the heat dissipation system, and extends the service life of the equipment.

Detailed Implementation

[0027] Example

[0028] Please see Figures 1-8In this embodiment of the invention, a dual-purpose (heating and cooling) intelligent energy-saving control cabinet includes a mounting base 1. A cabinet body 2 is fixedly connected to the upper end of the mounting base 1. A cabinet top 3 is fixedly connected to the upper end of the cabinet body 2. A center plate 4 is fixedly connected to the upper end of the cabinet top 3. Top covers 5 are rotatably connected to both sides of the center plate 4. Photovoltaic panels 6 are provided on the outer surface of the top covers 5. Cleaning components 7 are provided on the outer surface of the top covers 5. A support component 8 is fixedly connected to the outer side of the cabinet top 3. The cleaning component 7 includes a mounting plate 71 disposed on the upper end of the top cover 5. A mounting rod 72 is fixedly connected to one side of the mounting plate 71. A cleaning groove 73 is provided on the inner side of the mounting rod 72. A cleaning screw 74 is rotatably connected inside the cleaning groove 73. A threaded part 75 is threadedly connected to the outer surface of the cleaning screw 74. A snow scraper 76 is fixedly connected to the inner side of the threaded part 75. A synchronous pulley 77 is fixedly connected to the other end of the cleaning screw 74. The synchronous pulley 77 is driven by a synchronous belt 78. A synchronous motor 79 is fixedly connected to the other side of the mounting plate 71. The output shaft of the synchronous motor 79 is fixedly connected to the synchronous pulley 77.

[0029] Please see Figures 2-6 The support assembly 8 includes a support base 81 fixedly connected to the outside of the cabinet top 3. A support groove 82 is formed on the surface of the support base 81. A bidirectional screw 83 is rotatably connected inside the support groove 82. Moving parts 84 are threaded onto both sides of the outer surface of the bidirectional screw 83. A connecting rod 85 is fixedly connected to the upper end of each moving part 84. A support motor 86 is fixedly connected to the outside of the support base 81. The output shaft of the support motor 86 is fixedly connected to the bidirectional screw 83. The other end of the connecting rod 85 is slidably connected to the lower end of the top cover 5. An installation groove 87 is formed at the upper end of the connecting rod 85. A support pulley 88 is rotatably connected inside the installation groove 87. A support sliding groove is formed at the lower end of the top cover 5. 89. The support slide 89 and the support pulley 88 are slidably connected to each other; the start of the support motor 86 drives the bidirectional screw 83 in the support groove 82 to rotate. The moving parts 84 on both sides of the outer surface of the bidirectional screw 83 move synchronously in opposite directions through threaded engagement, driving the upper connecting rod 85 to move synchronously. The support pulley 88 at the upper end of the connecting rod 85 slides along the support slide 89 at the lower end of the top cover 5, guiding the top cover 5 to rotate around the center plate 4 to achieve the opening and closing angle adjustment. By adjusting the opening and closing angle of the top cover 5, the ventilation gap between the top cover 5 and the top of the cabinet 3 can be increased when the internal temperature of the control cabinet rises, forming a natural ventilation channel, accelerating the exhaust of hot air from the cabinet and the inflow of cold air from the outside, and improving the heat dissipation efficiency.

[0030] Please see Figure 3 and Figure 6The inner side of the connecting rod 85 is slidably connected to the outer side of the cabinet top 3. A limiting groove 12 is provided on the inner side of the connecting rod 85. A limiting slide 11 is fixedly connected to the outer side of the cabinet top 3. The limiting slide 11 and the limiting groove 12 are slidably connected. Hidden grooves 13 are provided on both sides of the outer surface of the limiting slide 11. Fixing through holes 14 are provided inside each hidden groove 13. Fixing screws 15 are inserted into each fixing through hole 14. The limiting slide 11 is threadedly connected to the cabinet top 3 via the fixing screws 15. The inner side of the connecting rod 85 and the outer side of the cabinet top 3 form a close sliding fit, while the limiting slide 11 on the outer side of the cabinet top 3 is precisely inserted into the inner side of the connecting rod 85. The limiting slide groove 12 forms a double sliding constraint. When the support component 8 drives the connecting rod 85 to move with the moving part 84, the limiting slide 11 slides synchronously along the limiting slide groove 12, which guides and limits the movement trajectory of the connecting rod 85 to prevent it from deviating or tilting. The limiting slide 11 is threadedly connected to the cabinet top 3 through the fixing through hole 14 and fixing screw 15 in the hidden groove 13. The hidden groove 13 can accommodate the fixing screw 15 to avoid damage and corrosion caused by exposure, ensuring that the limiting slide 11 is installed stably for a long time, thereby ensuring the structural stability of the connecting rod 85 during the sliding process and providing reliable support and guidance for the angle adjustment of the top cover 5.

[0031] Please see Figure 8 Rubber scrapers 19 are fixedly connected to both sides of the snow scraper 76. The lower end of the rubber scraper 19 is slidably connected to the surface of the photovoltaic panel 6. The rubber scraper 19 is fixedly connected to the snow scraper 76 by connecting screws 20. The rubber scrapers 19, which are fixed to both sides of the snow scraper 76 by connecting screws 20, move synchronously with the snow scraper 76 along the surface of the photovoltaic panel 6. The lower end of the rubber scraper 19 is in close contact with the surface of the photovoltaic panel 6. During the movement, it forms a flexible scraping of the snow on the surface. The fixing method of the connecting screws 20 ensures that the rubber scraper 19 is firmly connected to the snow scraper 76 and avoids falling off during snow scraping. The rubber scraper can adapt to the curvature of the photovoltaic panel 6 surface through its own elastic deformation to ensure that the snow is cleaned without dead corners. It can also avoid hard contact that scratches the coating of the photovoltaic panel 6. At the same time, its surface friction can enhance the snow scraping effect, achieving efficient snow removal while protecting the structure and photoelectric conversion performance of the photovoltaic panel 6.

[0032] Please see Figure 1Support rods 9 are fixedly connected to both sides of the upper end of the center plate 4. A protective plate 10 is fixedly connected to the upper end of the support rods 9. The protective plate 10 is located directly above the mounting plate 71. The support rods 9 on both sides of the upper end of the center plate 4 provide stable support for the protective plate 10, so that the protective plate 10 is suspended directly above the mounting plate 71 of the cleaning component 7. The protective plate 10 can directly block falling objects, branches, leaves and other foreign objects from hitting the mounting plate 71 and the cleaning component 7, so as to avoid damage to its structure and affect the snow removal function. At the same time, in snowy or rainy weather, the protective plate 10 can reduce the direct spray of rain and snow on the synchronous motor 79, synchronous wheel 77 and other electrical and transmission components, reduce the risk of moisture and corrosion, extend the service life of the cleaning component 7, and ensure that it can still stably drive the snow scraper 76 to complete the snow removal operation of the photovoltaic panel 6 in severe weather.

[0033] Please see Figure 4 Protective nets 18 are fixedly connected to both sides of the upper surface of the cabinet top 3, covering the upper surface of the cabinet top 3. The lower end of the top cover 5 is movably connected to the outer surface of the protective net 18. The protective nets 18 fixed to both sides of the upper surface of the cabinet top 3 form a complete coverage of the cabinet top 3 area. When the support component 8 drives the top cover 5 to rotate around the central plate 4 to open and close, the lower end of the top cover 5 remains in contact with the outer surface of the protective net 18. The protective net 18 can block leaves, dust, gravel and other debris from entering the gap between the top cover 5 and the cabinet top 3, avoiding debris from getting stuck in the rotating structure of the top cover 5 or accumulating on the surface of the cabinet top 3 and affecting heat dissipation. At the same time, when the top cover 5 is closed, the protective net 18 can play a buffer role, reducing direct collision and wear between the top cover 5 and the cabinet top 3. Moreover, its mesh structure does not affect the ventilation and heat dissipation of the cabinet top 3 area. While ensuring the structural protection effect, it maintains the unobstructed heat dissipation channel inside the control cabinet and ensures the stable operation of the equipment.

[0034] Please see Figure 5 A drive shaft 17 is rotatably connected to the inner side of the cabinet top 3. A drive plate 16 is fixedly connected to the outer surface of the drive shaft 17. Multiple drive plates 16 are provided, and the drive plates 16 are located at the center of the cabinet top 3. The drive shaft 17 on the inner side of the cabinet top 3 can rotate under external power or manual drive. The multiple drive plates 16 fixed on its outer surface rotate synchronously with the drive shaft 17. When the control cabinet needs to enhance internal ventilation and heat dissipation, the rotation of the drive plates 16 can accelerate the air flow in the area of ​​the cabinet top 3, forming an upward airflow guide, which promotes the rapid discharge of hot air in the cabinet through the gap between the top cover 5 and the cabinet top 3. At the same time, when it is necessary to adjust the airflow direction in the cabinet, the tilt direction of the drive plates 16 can be adjusted by controlling the rotation angle of the drive shaft 17, so as to realize the flexible switching of airflow guidance, assist in optimizing the heat dissipation efficiency in the cabinet, and ensure the stable operation of electrical components in a suitable temperature environment.

[0035] The working principle of this invention is as follows: First, the entire device is fixed by the mounting base 1. The core functions are achieved through the coordinated operation of multiple components, such as the top cover 5 adjustment, the photovoltaic panel 6 snow removal, and the cabinet heat dissipation. When the photovoltaic panel 6 is removing snow, the synchronous motor 79 of the cleaning component 7 is started. Its output shaft drives the synchronous wheel 77 to rotate. Through the synchronous belt 78, the cleaning screw 74 in the cleaning groove 73 of the mounting rod 72 rotates synchronously. The threaded part 75 drives the snow scraper 76 to move. The rubber scrapers 19 on both sides slide against the surface of the photovoltaic panel 6 with the snow scraper 76, flexibly scraping away the snow. The connecting screw 20 ensures that the rubber scraper 19 is stable. The protective plate 10 is suspended above the mounting plate 71 by the support rod 9 to prevent foreign objects from damaging the cleaning component 7. The angle adjustment of the top cover 5 depends on the support component 8. The support motor 86 drives the bidirectional screw 83 in the support groove 82 to rotate. The moving part 84 drives the cleaning component 76 to rotate. The connecting rod 85 moves synchronously, and the upper end of the connecting rod 85 supports the pulley 88, which slides along the lower end of the top cover 5 supporting the slide groove 89. At the same time, the inner limit slide groove 12 of the connecting rod 85 slides and engages with the outer limit slide seat 11 of the cabinet top 3, ensuring that the top cover 5 rotates smoothly around the central plate 4, realizing the adjustment of the opening and closing angle. When it snows, the tilt angle is increased to accelerate the snow to slide off. When it is sunny, the angle is adjusted to improve the light reception efficiency of the photovoltaic panel 6. When ventilating, the gap is increased to form a heat dissipation channel. The protective net 18 of the cabinet top 3 covers the upper surface to prevent debris from entering the gap between the top cover 5 and the cabinet top 3, and does not affect ventilation. When the inner drive shaft 17 of the cabinet top 3 rotates, multiple drive plates 16 rotate synchronously to accelerate the exhaust of hot air inside the cabinet and help optimize the heat dissipation efficiency. The precise cooperation of each component ensures both stable photovoltaic power supply and snow removal effect, and achieves efficient heat dissipation inside the cabinet, meeting the energy-saving operation requirements for both heating and cooling.
