Description

Technical Field

[0001] This utility model relates to the field of photovoltaic energy storage technology, specifically to an electrical cabinet with good heat dissipation for photovoltaic energy storage. Background Technology

[0002] With increasing global focus on renewable energy, photovoltaic (PV) energy storage technology is gaining increasing attention. As a crucial component of the renewable energy sector, PV energy storage cabinets play a key role in solar photovoltaic power generation systems. These cabinets not only store the electrical energy generated by solar photovoltaic arrays but also release energy during peak electricity demand periods to alleviate grid pressure. However, existing PV energy storage cabinets have some shortcomings in heat dissipation and internal structural design, affecting their performance and lifespan.

[0003] In traditional designs, the internal carrier plates of electrical cabinets are usually fixed, which leads to problems such as varying equipment heights and heat accumulation. Especially for tall equipment, fixed carrier plates cannot provide sufficient ventilation and heat dissipation channels, making it difficult to effectively dissipate heat and thus affecting the normal operation and lifespan of the equipment. To address this, we propose an electrical cabinet with good heat dissipation for photovoltaic energy storage. Summary of the Invention

[0006] Preferably, a first positioning tooth block is fixedly installed on the periphery of the first threaded sleeve, and a second positioning tooth block is fixedly installed on the periphery of the connecting seat. The positioning tooth sleeve is inserted and installed on the periphery of the first positioning tooth block and the second positioning tooth block.

[0007] Preferably, a connecting ring is fixedly installed on the lower periphery of the first threaded sleeve, and a spring is sleeved around the periphery of the first threaded sleeve, the spring being snapped between the connecting ring and the second threaded sleeve.

[0008] Preferably, an air outlet is provided on the outer wall of the cabinet, an air inlet pipe is fixedly installed at the outer end of the cabinet, and a fan is fixedly installed inside the air inlet pipe.

[0009] Preferably, the column has a through cavity on its outer periphery, the base has an air guide hole on its inner wall, the two ends of the air guide hole are respectively connected to the through cavity and the air inlet pipe, and the column has a through hole on its outer wall that is connected to the through cavity.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This photovoltaic energy storage electrical cabinet with good heat dissipation allows for the adjustment of the spacing between various carrier plates within the cabinet based on the size of the electrical appliance and heat dissipation requirements via a threaded connection between the first threaded sleeve and the threaded groove. Furthermore, the carrier plates can be positioned by the insertion connection between the positioning toothed sleeve, the first threaded sleeve, and the connecting seat.

[0012] This type of photovoltaic energy storage electrical cabinet with good heat dissipation is equipped with an air inlet pipe. Through its internal fan, external air can be injected into the column, and through the through holes, the air can be evenly distributed to the upper part of each carrier plate to achieve the effect of heat dissipation for the electrical appliances.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-7 This utility model provides a technical solution: an electrical cabinet with good heat dissipation for photovoltaic energy storage, including a base 1, a photovoltaic panel 11 and a cabinet body 2 fixedly installed on the upper end of the base 1, a plurality of carrier plates 21 provided inside the cabinet body 2, a column 22 fixedly installed inside the cabinet body 2, a plurality of photovoltaic panels 11 slidably installed on the periphery of the column 22, a threaded curved groove 25 opened on the periphery of the column 22, a connecting seat 23 fixedly installed on the lower end of the carrier plate 21, a first threaded sleeve 24 threadedly connected to the threaded curved groove 25 is rotatably installed on the lower end of the connecting seat 23, a positioning toothed sleeve 3 is inserted and installed on the periphery of the first threaded sleeve 24 and the positioning toothed sleeve 3 is rotatably installed on the periphery of the first threaded sleeve 24 and threadedly connected to the positioning toothed sleeve 3.

[0027] Working principle: When it is necessary to adjust the spacing between each carrier plate 21 according to the height of the appliance and the heat dissipation requirements, the first threaded sleeve 24 can be rotated at the lower end of the connecting seat 23. With the column 22 restricting the movement direction of the connecting seat 23 through its plug-in connection with the column 23, the rotating first threaded sleeve 24 can drive the carrier plate 21 to move up and down through its threaded connection with the column 22, thereby achieving the effect of adjusting the spacing between adjacent carrier plates 21.

[0028] The second threaded sleeve 33 can be rotated around the first threaded sleeve 24. Through the threaded connection between the second threaded sleeve 3 and the positioning toothed sleeve 3, the positioning toothed sleeve 3 is driven to move, so that the positioning toothed sleeve 3 is inserted into the first threaded sleeve 24 and the connecting seat 23, thereby achieving the effect of positioning the first threaded sleeve 24 and the carrier plate 21.

[0029] As a further description of the above technical solution: a first positioning tooth block 31 is fixedly installed on the periphery of the first threaded sleeve 24, a second positioning tooth block 32 is fixedly installed on the periphery of the connecting seat 23, and a positioning tooth sleeve 3 is inserted and installed on the periphery of the first positioning tooth block 31 and the second positioning tooth block 32; a connecting ring 34 is fixedly installed on the lower periphery of the first threaded sleeve 24, and a spring 35 is sleeved on the periphery of the first threaded sleeve 24, and the spring 35 is snapped and installed between the connecting ring 34 and the second threaded sleeve 33.

[0030] Specifically, through the insertion connection between the first positioning tooth block 31 and the positioning tooth sleeve 3, the movement direction of the positioning tooth sleeve 3 can be restricted around the first threaded sleeve 24, so that the rotating second threaded sleeve 33 can drive the positioning tooth sleeve 3 to move up and down through the threaded connection between it and the positioning tooth sleeve 3. Through the insertion connection between the positioning tooth sleeve 3 and the first positioning tooth block 31 and the second positioning tooth block 32, the first threaded sleeve 24 can be positioned.

[0031] The spring 35 is provided to extend the connecting ring 34 and the second threaded sleeve 33 outward around the first threaded sleeve 24, thus preventing the second threaded sleeve 33 from becoming loose.

[0032] As a further description of the above technical solution: an air outlet 45 is provided on the outer wall of the cabinet 2, an air inlet pipe 4 is fixedly installed on the outer end of the cabinet 2, and a fan 41 is fixedly installed inside the air inlet pipe 4; a through cavity 42 is provided on the periphery of the column 22, an air guide hole 43 is provided on the inner wall of the base 1, the two ends of the air guide hole 43 are respectively connected to the through cavity 42 and the air inlet pipe 4, and a through hole 44 is provided on the outer wall of the column 22 that is connected to the through cavity 42.

[0033] Specifically, when it is necessary to dissipate heat from the electrical appliances inside the cabinet 2, the fan 41 is turned on. In the air inlet pipe 4, in conjunction with the air guide hole 43, outside air can be injected into the cavity 42. Then, through the various through holes 44 around the cavity 42, the air can be evenly sprayed out on the upper side of each carrier plate 21 to achieve the effect of dissipating heat from the electrical appliances.
