Technical Field

[0001] This application relates to the field of solar photovoltaic power generation technology, and in particular to an outdoor energy storage cabinet. Background Technology

[0002] Solar photovoltaic (PV) power generation is the process of converting photons from solar radiation into electrical energy through the photovoltaic effect. It mainly consists of solar panels and inverters. With the rapid development of new energy storage technologies and the widespread adoption of outdoor communication base stations, emergency power supply sites, and distributed PV energy storage systems, outdoor energy storage cabinets, as the core support and protection devices for energy storage equipment, have become a focus of industry attention due to their environmental adaptability, operational stability, and ease of maintenance. These cabinets need to be exposed to complex outdoor environments for extended periods, resisting not only the corrosive effects of high and low temperatures, wind, rain, dust, and ultraviolet radiation, but also providing a stable operating environment for internal precision equipment such as energy storage batteries, inverters, and controllers. Simultaneously, they must meet the requirements for convenient equipment installation and maintenance to ensure the long-term reliable operation of the energy storage system.

[0003] However, existing devices cannot cool the internal energy storage batteries in real time, and it is inconvenient for staff to install and fix the energy storage batteries. To solve the above problems, an outdoor energy storage cabinet is proposed. Utility Model Content

[0004] The purpose of this application is to provide an outdoor energy storage cabinet that has the advantages of being able to cool the energy storage battery inside the device in real time and facilitating the installation and fixing of the energy storage battery.

[0005] This application provides an outdoor energy storage cabinet with the following technical solution: An outdoor energy storage cabinet includes a mounting plate and a housing. The housing is fixedly connected to the upper surface of the mounting plate. A cooling chamber is provided inside the housing. Semiconductor coolers are embedded on both sides of the cooling chamber. A circulation pump is provided inside the cooling chamber. A temperature-conducting coil is provided inside the housing. One end of the temperature-conducting coil is fixedly connected to the circulation pump. A temperature-conducting plate overlaps the surface of the temperature-conducting coil. Insulation cotton is fixedly connected to the inner wall of the housing. The insulation cotton is placed between the housing and the temperature-conducting coil. The other end of the temperature-conducting coil passes through the interior of the cooling chamber. A temperature sensor is provided inside the housing. A placement slot is provided inside the housing. A ventilation mesh is embedded on the surface of the placement slot. A positioning slot is formed on the surface of the placement slot. An adjustment and positioning mechanism is fixedly connected inside the housing.

[0006] By adopting the above technical solution, through the cooperation of the cooling chamber, semiconductor cooler, circulating pump, temperature-conducting coil, and temperature-conducting plate, cold energy can be efficiently transferred to achieve uniform cooling inside the chamber. Combined with the inner wall insulation cotton to reduce cold energy loss, the suitable temperature environment required by the energy storage battery can be stably maintained, effectively avoiding the impact of high temperature on equipment performance, extending the service life of the equipment, and under the action of temperature sensor, the internal temperature of the chamber can be detected in real time. Through the transmission action of the first bevel gear and the second bevel gear, as well as the cooperation of the threaded column and the threaded tube, the positioning slot of the placement slot can be accurately aligned, which facilitates the positioning and fixing of the energy storage battery in the placement slot and adapts to the installation requirements of equipment of different sizes.

[0008] By adopting the above technical solution, the cooperation between the slide rail inside the box and the pulley on the lower surface of the placement slot allows the placement slot to slide flexibly along the slide rail, making it easy to pull the placement slot out of the box for placement or maintenance of the energy storage battery, and also easy to push it back into the box, reducing the operational difficulty in the equipment installation and maintenance process and improving work efficiency.

[0009] Preferably, the adjustment and positioning mechanism includes an adjustment chamber, which is fixedly connected inside the housing.

The first bevel gear and the second bevel gear mesh with each other.

[0010] By adopting the above technical solution, two sets of symmetrical threaded columns with opposite thread directions can drive the two sets of threaded tubes to move simultaneously towards or away from each other when the first rotating shaft knob is turned. This can quickly complete the positioning, fixing or loosening operation of the placement slot. Not only is the fixing stability stronger, but no additional tools are required. It can be operated manually by turning the knob, simplifying the operation process and improving the equipment fixing efficiency.

[0011] Preferably, threaded columns are fixedly connected to both ends of the second rotating shaft, the threads on the surfaces of the two sets of threaded columns are opposite in direction, and each set of threaded columns is fitted with a threaded tube that matches the positioning groove.

[0012] By adopting the above technical solution, the sliding cooperation between the slider on the surface of the threaded tube and the sliding groove in the adjustment chamber can limit the rotation of the threaded tube with the threaded column, ensuring that the threaded tube only moves along the direction of the sliding groove, thereby accurately aligning with the positioning groove of the placement groove, avoiding the problem of inaccurate positioning due to the offset of the threaded tube, and ensuring the accuracy of equipment fixation.

[0013] Preferably, the housing is movably connected to a protective door via a hinge, and the surface of the protective door is provided with a latch, and the housing and the protective door are fixedly connected by the latch.

[0014] By adopting the above technical solution, the protective door is connected to the cabinet via hinges. When closed, it can isolate outdoor wind, rain, dust and foreign objects, protecting the energy storage batteries and components inside the cabinet from external environmental corrosion. At the same time, the latch can firmly fix the protective door to the cabinet, improving the cabinet's sealing and security, and preventing equipment from being stolen or accidentally touched.

[0015] Preferably, a liquid exchange pipe is fixedly connected to the surface of the housing, and the liquid exchange pipe passes through the refrigeration chamber, and a solenoid valve is provided on the surface of the liquid exchange pipe.

[0016] By adopting the above technical solution, the coolant exchange pipe running through the refrigeration chamber facilitates the replenishment or replacement of the coolant in the refrigeration chamber, while the solenoid valve on the surface of the coolant exchange pipe can precisely control the opening and closing of the coolant exchange channel, avoid coolant leakage, simplify the maintenance operation of the refrigeration system, and ensure the continuous and stable operation of the refrigeration system.

[0017] Preferably, the surface of the mounting plate is fixedly connected with a fixing block. There are two sets of fixing blocks, which are symmetrically arranged on both sides of the mounting plate. The surface of the fixing block is provided with a threaded hole so that a fixing bolt can pass through it.

[0018] By adopting the above technical solution, the fixing blocks on both sides of the mounting plate and the fixing bolts in the threaded holes can firmly fix the entire cabinet to the outdoor ground or mounting foundation, effectively resisting the impact of outdoor wind, vibration and other factors on the cabinet, preventing the cabinet from shifting or tipping over, and improving the stability and wind and earthquake resistance of the cabinet after installation.

[0019] Preferably, a control switch is fixedly connected to the surface of the enclosure, and a microprocessor is installed inside the control switch. The enclosure is made of cold-rolled steel plate and the surface is treated with electrostatic powder coating. By adopting the above technical solution, the microprocessor in the control switch can receive the detection signal from the temperature sensor and automatically control the start and stop of the semiconductor cooler and the circulating pump to achieve intelligent temperature regulation inside the cabinet. At the same time, the cabinet is made of cold-rolled steel plate and treated with electrostatic powder coating, which not only ensures the structural strength of the cabinet, but also improves its corrosion resistance and UV resistance, enabling it to adapt to harsh outdoor environments and extend the overall service life of the cabinet.

[0023] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0024] Example 1: An outdoor energy storage cabinet, referring to Figure 1 , Figure 3 and Figure 4The system includes a mounting plate 1 and a housing 2. The housing 2 is fixedly connected to the upper surface of the mounting plate 1. A cooling chamber 3 is located inside the housing 2. Semiconductor coolers 4 are embedded on both sides of the cooling chamber 3. A circulation pump 5 is installed inside the cooling chamber 3. A temperature-conducting coil 7 is installed inside the housing 2. Through the cooperation of the cooling chamber 3, semiconductor coolers 4, circulation pump 5, temperature-conducting coil 7, and temperature-conducting plate 8, cold energy can be efficiently transferred, achieving uniform cooling within the housing 2. Combined with the inner wall insulation cotton 6 to reduce cold energy loss, the system can stably maintain the suitable temperature environment required by the energy storage battery, effectively avoiding the impact of high temperatures on equipment performance, extending equipment lifespan, and, with the help of a temperature sensor 9, can monitor the temperature inside the housing 2 in real time. One end of the temperature-conducting coil 7 is fixedly connected to the circulation pump 5. A temperature-conducting plate 8 overlaps the surface of the temperature-conducting coil 7. Insulation cotton 6 is fixedly connected to the inner wall of the box 2. The insulation cotton 6 is placed between the box 2 and the temperature-conducting coil 7. The other end of the temperature-conducting coil 7 passes through the interior of the refrigeration chamber 3. A temperature sensor 9 is installed inside the box 2. A placement slot 11 is installed inside the box 2. A ventilation mesh 12 is embedded on the surface of the placement slot 11. A positioning slot 13 is opened on the surface of the placement slot 11. An adjustment and positioning mechanism 32 is fixedly connected inside the box 2. Through the transmission action of the first bevel gear 17 and the second bevel gear 19 inside the adjustment chamber 15, and the cooperation of the threaded column 20 and the threaded tube 21, the positioning slot 13 of the placement slot 11 can be accurately aligned, which facilitates the positioning and fixing of the energy storage battery in the placement slot 11 and adapts to the installation requirements of equipment of different sizes.

[0025] Please see Figure 2 , Figure 3 and Figure 4The interior of the housing 2 is fixedly connected to a slide rail 10, and the lower surface of the placement slot 11 is fixedly connected to a pulley 14. The pulley 14 is movably connected inside the slide rail 10. There are two sets of pulleys 14 and two sets of slide rail 10, which are symmetrically arranged inside the housing 2. The cooperation between the slide rail 10 inside the housing 2 and the pulley 14 on the lower surface of the placement slot 11 allows the placement slot 11 to slide flexibly along the slide rail 10. This makes it easy to pull the placement slot 11 out of the housing 2 to place or inspect the energy storage battery, and also easy to push it back into the housing 2, reducing the operational difficulty during equipment installation and maintenance. To improve operational efficiency, the adjusting positioning mechanism 32 includes an adjusting chamber 15, which is fixedly connected inside the housing 5. A bearing is fixedly connected inside the adjusting chamber 15 to allow a first rotating shaft 16 to pass through it. One end of the first rotating shaft 16 is fixedly connected to a first bevel gear 17. A bearing is also fixedly connected inside the adjusting chamber 15 to allow a second rotating shaft 18 to pass through it. A second bevel gear 19 is fixedly connected to the surface of the second rotating shaft 18. The first bevel gear 17 and the second bevel gear 19 mesh with each other, forming two sets of symmetrical threads with opposite directions. The threaded posts 20, when the knob 24 of the first rotating shaft 16 is rotated, can drive the two sets of threaded tubes 21 to move simultaneously in opposite directions, enabling quick positioning and loosening of the placement groove 11. This not only provides stronger stability but also eliminates the need for additional tools, allowing for manual operation via the knob 24, simplifying the process and improving equipment fixing efficiency. Both ends of the second rotating shaft 18 are fixedly connected to threaded posts 20, with the threads on the surfaces of the two sets of threaded posts 20 having opposite directions. Each set of threaded posts 20 is fitted with a threaded tube 21 that matches the positioning groove 13. The first rotating shaft 1... A knob 24 is fixedly connected to one end of the 6, and a slider 22 is fixedly connected to the surface of the threaded tube 21. A groove 23 is opened inside the adjustment chamber 15, and the slider 22 is movably connected inside the groove 23. The sliding cooperation between the slider 22 on the surface of the threaded tube 21 and the groove 23 inside the adjustment chamber 15 can limit the rotation of the threaded tube 21 with the threaded column 20, ensuring that the threaded tube 21 only moves along the direction of the groove 23, thereby accurately aligning with the positioning groove 13 of the placement groove 11, avoiding the problem of inaccurate positioning due to the offset of the threaded tube 21, and ensuring the accuracy of equipment fixation.

[0026] Please see Figure 1 , Figure 2 and Figure 5The enclosure 2 is connected to a protective door 25 via hinges. A latch 26 is provided on the surface of the protective door 25. The enclosure 2 and the protective door 25 are fixedly connected via the latch 26. When closed, the protective door 25 isolates the enclosure from outdoor wind, rain, dust, and foreign objects, protecting the energy storage batteries and components inside the enclosure 2 from external environmental corrosion. Simultaneously, the latch 26 securely fixes the protective door 25 to the enclosure 2, improving the cabinet's sealing and security, preventing equipment theft or accidental contact. A coolant exchange pipe 28 is fixedly connected to the surface of the enclosure 2, and the coolant exchange pipe 28 penetrates the cooling chamber 3. A solenoid valve 29 is provided on the surface of the coolant exchange pipe 28. The coolant exchange pipe 28, penetrating the cooling chamber 3, facilitates the replenishment or replacement of coolant within the cooling chamber 3. The solenoid valve 29 on the surface of the coolant exchange pipe 28 precisely controls the opening and closing of the coolant exchange channel, preventing coolant leakage, simplifying the maintenance of the refrigeration system, and ensuring the continuous and stable operation of the refrigeration system.

[0027] Please see Figure 1 , Figure 2 and Figure 5 The mounting plate 1 has two sets of fixing blocks 30 fixedly connected to its surface. These blocks are symmetrically arranged on both sides of the mounting plate 1. Each fixing block 30 has threaded holes for mounting bolts 31 to pass through. The fixing blocks 30 on both sides of the mounting plate 1 and the mounting bolts 31 in the threaded holes securely fix the entire cabinet to the outdoor ground or mounting foundation, effectively resisting the effects of outdoor wind and vibration, preventing the cabinet from shifting or tipping over, and improving the stability and wind and earthquake resistance of the cabinet after installation. The surface of the enclosure 2 is also fixedly connected to control... Switch 27 contains a microprocessor. The enclosure 2 is made of cold-rolled steel plate with electrostatic powder coating. The microprocessor in the control switch 27 can receive the detection signal from the temperature sensor 9 and automatically control the start and stop of the semiconductor cooler 4 and the circulation pump 5 to achieve intelligent temperature regulation inside the enclosure 2. At the same time, the enclosure 2 is made of cold-rolled steel plate with electrostatic powder coating, which not only ensures the structural strength of the enclosure 2, but also improves its corrosion resistance and UV resistance, enabling it to adapt to harsh outdoor environments and extend the overall service life of the cabinet.

[0028] The implementation principle of this application embodiment is as follows: First, the mounting plate 1 of the device is placed in the designated installation position. Through the threaded holes of the fixing blocks 30 on both sides of the mounting plate 1, the fixing bolts 31 are inserted and screwed into the preset holes in the ground or installation foundation to make the device firmly fixed and prevent displacement during subsequent use. The protective door 25 of the box 2 is opened, and the placement slot 11 is pulled. At this time, the pulley 14 on the lower surface of the placement slot 11 slides along the slide rail 10 inside the box 2, pulling the placement slot 11 out of the box 2. The energy storage battery is placed in the placement slot 11, and then the placement slot 11 is pushed to slide back into the box 2 along the slide rail 10. The knob 24 at one end of the first rotating shaft 16 is rotated to drive the first rotating shaft 16 and the first bevel gear 17 on the surface to rotate. Under the meshing transmission of the first bevel gear 17 and the second bevel gear 19, the second rotating shaft 18 and the two sets of threaded columns 20 on the surface are rotated. Then the threaded columns 20 are connected to the second rotating shaft 18 and the two sets of threaded columns 20 on the surface. The battery moves through the threaded tube 21. Under the limiting action of the slider 22 and the slide groove 23, the threaded tube 21 moves along the slide groove 23. The two sets of threaded tubes 21 move towards each other at the same time and are inserted into the positioning groove 13 of the placement groove 11 to complete the positioning and fixing of the energy storage battery. Finally, the protective door 25 is closed and the lock 26 is fastened. The temperature sensor 9 inside the box 2 detects the temperature inside the box in real time and transmits the temperature signal to the microprocessor in the control switch 27. If the detected temperature is higher than the suitable temperature threshold of the energy storage battery, the microprocessor controls the semiconductor cooler 4 to start and cool the coolant in the cooling chamber 3. At the same time, the circulation pump 5 is started so that the cooled coolant circulates along the temperature conducting coil 7. The temperature conducting plate 8 on the surface of the temperature conducting coil 7 evenly transfers the cooling energy of the coolant to the box 2, thereby cooling the inside of the box 2. The insulation cotton 6 on the inner wall of the box 2 reduces the loss of cooling energy to the outside and maintains the stable temperature inside the box.
