Description

Technical Field

[0001] This utility model relates to the field of energy storage battery technology, specifically a high-voltage AC inverter DC energy storage battery device. Background Technology

[0002] A battery is a device that converts chemical energy into electrical energy. It contains an electrolyte solution and metal electrodes to generate current. It is a cup, tank, or other container or composite container that contains a portion of the space. It has positive and negative electrodes. With the advancement of technology, the term "battery" now generally refers to a small device that can generate electrical energy. There are many battery products, among which the high-voltage AC inverter DC energy storage battery device is one.

[0003] A search revealed a high-voltage AC inverter DC energy storage battery device with application number 202222354493.1. This device uses a snap-fit ​​assembly to fix the battery relatively within the housing, preventing it from shaking. When the battery needs to be removed, the snap-fit ​​assembly is disengaged by turning the handle, allowing the battery to be removed. This device allows operators to fix the battery relatively without manual adjustment after insertion, reducing their workload. However, when removing the battery, if the rotating gear is not locked after the snap-fit ​​block is disengaged from the fixing block, the curved surface of the sliding block can easily cause the pressing block to rotate on its own under the action of spring force, causing the snap-fit ​​block to return to its original position. Removing the battery requires one hand to hold the handle to prevent rotation while the other hand is used to remove the battery, or it may require two people to remove it, which is very inconvenient. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a high-voltage AC inverter DC energy storage battery device to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-voltage AC inverter DC energy storage battery device, comprising a protective shell, a pull-out box inside the protective shell, a rotating rod connected to the top side of the pull-out box, cover plates connected to both ends of the rotating rod, a torsion spring connected to the outer surface of the rotating rod, a spring located at the bottom inside the pull-out box, a support plate connected to the top of the spring, sliders connected to both sides of the support plate, a battery body located on the top of the support plate, a fixed column connected to one side inside the pull-out box, a limit groove and a sliding groove formed on the inner wall of the fixed column, a counterweight frame connected within the sliding groove, a wire hole inside the counterweight frame, and a soft pad inside the wire hole, an inverter connected to one side of the fixed column, a cover connected to one side of the pull-out box, and a control panel located on one side of the cover.

[0006] Furthermore, a cooling fan is provided on one side of the inner side of the protective shell, and a heat dissipation vent is opened on one side of the protective shell, with a dustproof mesh connected inside the heat dissipation vent.

[0007] By adopting the above technical solution, when the battery device is working, the air inside the device is replaced with the outside air through the heat dissipation vent under the blowing of the cooling fan, thereby cooling the inside of the device and avoiding excessive temperature, which would accelerate the aging of the battery body. The air is filtered by the dust filter to prevent dust from entering the device.

[0008] Furthermore, the number of springs is four, and the four springs are arranged in a rectangular array.

[0009] By adopting the above technical solution, during installation, the cover plate rotates and presses against the battery body under the pressure of the protective shell, thereby compressing the spring on the support plate. When maintaining the battery body, after the cover plate is exposed from the protective shell, the spring force pushes the support plate and the battery body upward, so that the battery body is exposed from the pull-out box, making it convenient for staff to take it out.

[0010] Furthermore, the support plate is slidably connected to the limiting groove via a slider.

[0011] By adopting the above technical solution, the displacement distance of the support plate is limited by the cooperation of the limiting groove and the slider, so as to avoid the battery body being ejected from the pull-out box due to excessive elasticity during battery body maintenance, which could cause injury to the staff.

[0012] Furthermore, the counterweight frame has an "I" shaped cross-section.

[0013] By adopting the above technical solution, the power cord is pulled by the weight of the counterweight frame itself, so that the power cord is always in a taut state, and the power cord is prevented from getting tangled when the battery body moves the power cord up and down.

[0014] Furthermore, the slide is provided in two sets, and the two sets of slides are symmetrically distributed. The cross-section of the slide is convex, and the counterweight frame is slidably connected to the slide.

[0015] By adopting the above technical solution, the power cord moves up or down in the chute through the counterweight frame during the process of rising and falling, driven by the battery body. This allows the counterweight frame to tighten the power cord while avoiding excessive pulling that could break the power cord and affect the practicality of the device.

[0016] Furthermore, the inner wall of the protective shell is provided with a movable groove, and a movable block is connected to one side of the pull-out box, and the movable block is slidably connected to the movable groove.

[0017] By adopting the above technical solution, when the pull-out box is pulled out of the protective shell, the movement distance of the pull-out box is limited by the cooperation of the movable block and the movable slot, so as to avoid excessive pulling and pulling the pull-out box out of the protective shell, which would affect the practicality of the device.

[0018] Furthermore, the positive and negative terminals of the battery body are connected to power lines, which pass through the wiring holes and are electrically connected to the inverter, and the outer surface of the power lines is in contact with the soft pad.

[0019] By adopting the above technical solution, the soft pad is made of rubber, which cushions the power cord and the counterweight frame, preventing the counterweight frame from scratching the power cord.

[0020] Furthermore, the cover is detachably connected to the protective housing by bolts.

[0021] By adopting the above technical solution, threaded holes are opened on one side of both the cover and the protective shell. By inserting bolts into the threaded holes, the cover and the protective shell are connected as a whole, protecting the battery body and preventing the pull-out box from sliding due to external forces.

[0022] Furthermore, the top of the support plate is provided with a number of heat dissipation holes, and the number of heat dissipation holes are distributed in a rectangular array.

[0023] By adopting the above technical solution, the heat generated by the battery body during operation enters the cavity at the bottom of the pull-out box through the heat dissipation holes. Driven by the fan, the heat is dissipated through the heat dissipation vents, thus preventing the internal temperature of the pull-out box from becoming too high and affecting the normal operation of the battery.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model, by incorporating a pull-out box, spring, torsion spring, cover plate, and rotating rod, allows the power cord, inverter, and other components to be installed and connected. Pushing the cover pulls the pull-out box into the protective housing. Simultaneously, the protective housing compresses the cover plate, which, in conjunction with the rotating rod and torsion spring, compresses the battery body. This, in turn, causes the support plate to compress the spring, completely squeezing the battery body into the pull-out box and securing it, achieving rapid fixation and protection of the battery body. Furthermore, in the event of an accidental drop, the spring cushions the impact on the battery body. When maintenance is required, once the cover plate protrudes from the protective housing, the spring force pushes the support plate and battery body upwards, exposing the battery body in the pull-out box, making retrieval more convenient and faster.

[0026] 2. This utility model is equipped with a sliding groove, a counterweight frame, and a soft pad. The counterweight frame uses its own weight to pull the power cord, keeping the power cord taut at all times and preventing it from getting tangled during the battery body's ascent and descent. The soft pad cushions the power cord and the counterweight frame, preventing the counterweight frame from scratching the power cord. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] Example 1: A high-voltage AC inverter DC energy storage battery device, such as Figures 1-6As shown, the device includes a protective outer shell 1, inside which is a pull-out box 2. A rotating rod 6 is connected to the top of the pull-out box 2, and cover plates 8 are connected to both ends of the rotating rod 6. A torsion spring 7 is connected to the outer surface of the rotating rod 6. A spring 3 is located at the bottom inside the pull-out box 2, and a support plate 4 is connected to the top of the spring 3. Slider blocks 11 are connected to both sides of the support plate 4. A battery body 5 is located on the top of the support plate 4. A fixing post 9 is connected to one side inside the pull-out box 2. A limit groove 10 and a sliding groove 13 are formed on the inner wall of the fixing post 9. A counterweight frame 14 is connected in the sliding groove 13. The counterweight frame 14 has a wire hole inside, and the wire hole contains a... An inverter 20 is connected to one side of the soft pad 15 and the fixing column 9. A cover 18 is connected to one side of the pull-out box 2. A control panel 19 is provided on one side of the cover 18. A cooling fan 21 is provided inside the protective shell 1. A heat dissipation vent is opened on one side of the protective shell 1, and a dustproof net 22 is connected inside the heat dissipation vent. When the battery device is working, the air inside the device is replaced with the outside air through the heat dissipation vent under the blowing of the cooling fan 21, thereby cooling the inside of the device and avoiding excessive temperature and accelerated aging of the battery body 5. The dustproof net 22 filters the air to prevent dust from entering the inside of the device.

[0037] See Figure 5 and Figure 6 In the above embodiment, there are four springs 3, and the four springs 3 are arranged in a rectangular array. During installation, under the pressure of the protective shell 1, the cover plate 8 rotates and presses against the battery body 5, thereby causing the support plate 4 to compress the springs 3. When maintaining the battery body 5, after the cover plate 8 is exposed from the protective shell 1, under the elastic force of the springs 3, the support plate 4 and the battery body 5 are pushed upward, so that the battery body 5 is exposed from the pull-out box 2, making it convenient for staff to take it out.

[0038] See Figure 6 In the above embodiment, the support plate 4 is slidably connected to the limiting groove 10 through the slider 11. The limiting groove 10 cooperates with the slider 11 to limit the displacement distance of the support plate 4, so as to avoid the battery body 5 being ejected from the pull-out box 2 by excessive elasticity when maintaining the battery body 5, which would cause injury to the staff.

[0039] See Figure 1 , Figure 4 and Figure 5 In the above embodiment, the inner wall of the protective shell 1 is provided with a movable groove 16, and a movable block 17 is connected to one side of the pull-out box 2. The movable block 17 is slidably connected to the movable groove 16. When the pull-out box 2 is pulled out of the protective shell 1, the movable block 17 cooperates with the movable groove 16 to limit the movement distance of the pull-out box 2, so as to avoid excessive pulling and pulling the pull-out box 2 out of the protective shell 1, which would affect the practicality of the device.

[0040] See Figure 1 and Figure 2In the above embodiment, the cover 18 is detachably connected to the protective shell 1 by bolts. Both the cover 18 and the protective shell 1 have threaded holes on one side. By inserting the bolts into the threaded holes, the cover 18 and the protective shell 1 are connected as a whole to protect the battery body 5 and prevent the pull-out box 2 from sliding due to external forces.

[0041] See Figure 6 In the above embodiment, the top of the support plate 4 is provided with a plurality of heat dissipation holes 23, and the plurality of heat dissipation holes 23 are distributed in a rectangular array. The heat generated by the battery body 5 during operation enters the bottom cavity of the pull-out box 2 through the heat dissipation holes 23. Driven by the fan, the heat is dissipated through the heat dissipation vent, so as to avoid the internal temperature of the pull-out box 2 being too high and affecting the normal operation of the battery.

[0042] See Figure 1 and Figure 6 In the above embodiment, the positive and negative terminals of the battery body 5 are connected to power lines 12. The power lines 12 pass through the wire hole and are electrically connected to the inverter 20. The outer surface of the power lines 12 is in contact with the soft pad 15. The soft pad 15 is made of rubber. The soft pad 15 buffers the power lines 12 and the counterweight frame 14 to prevent the counterweight frame 14 from scratching the power lines 12.

[0043] Example 2: To prevent the power cord 12 from getting tangled during the rising and falling of the battery body 5, Example 2 is an improvement on Example 1. (See attached document.) Figure 6 The counterweight frame 14 has an "I" shaped cross section. The counterweight frame 14 uses its own weight to pull the power cord 12, keeping the power cord 12 taut at all times, thus preventing the power cord 12 from getting tangled during the process of the battery body 5 driving the power cord 12 to rise and fall.

[0044] See Figure 6 In the above embodiment, there are two sets of slide grooves 13, and the two sets of slide grooves 13 are symmetrically distributed. The cross-section of the slide groove 13 is convex. The counterweight frame 14 is slidably connected to the slide groove 13. Under the drive of the battery body 5, the power cord 12 moves up or down in the slide groove 13 through the counterweight frame 14 during the rising and falling process. This allows the counterweight frame 14 to tighten the power cord 12 while avoiding excessive pulling that could break the power cord 12 and affect the practicality of the device.

[0045] The implementation principle of this utility model is as follows: During installation, the operator first installs the inverter 20, control panel 19, and cooling fan 21. Then, the power cord 12 is passed through the counterweight frame 14 and connected to the positive and negative terminals of the battery body 5. The battery body 5 is then placed on the support plate 4. Under the action of its own weight, the battery body 5 drives the support plate 4 to compress the spring 3 and move down a small distance. At the same time, the counterweight frame 14 moves within the slide groove 13 under its own weight, tauting the power cord 12. At this time, the cover 18 is pushed, causing the pull-out box 2 to enter the protective shell 1. As the pull-out box 2 enters the protective shell 1, the protective shell 1 presses against the cover plate 8, which, in conjunction with the torsion spring 7 of the rotating rod 6, causes the cover plate 8 to press against the battery body 5, thereby compressing the battery body 5. The battery body 5 is completely squeezed into the pull-out box 2 and fixed in place. The cover 18 is then connected to the protective shell 1 as a whole and sealed with bolts, thus completing the assembly. When the battery body 5 is damaged and needs to be replaced, the operator loosens the bolts and pulls the cover plate to move the pull-out box 2 away from the protective shell 1. Under the action of the pull-out box 2, the movable block 17 slides in the movable groove 16, which limits the pull-out box 2. When the movable block 17 is located on one side of the movable groove 16, the cover plate 8 is located outside the protective shell. Under the action of the spring 3, the support plate 4 moves the battery body 5 upward. As the battery body 5 moves upward, it opens the cover plate 8 and cooperates with the torsion spring 7 to open the cover plate 8, thus exposing the battery body 5 to the pull-out box 2 for easy access by the operator.
