Description

Technical Field

[0001] This utility model relates to the field of energy storage cabinet design technology, and in particular to a mobile energy storage cabinet. Background Technology

[0002] With the global energy structure transformation and the popularization of distributed energy, energy storage technology has become the key to solving the intermittency of renewable energy and improving the flexibility of the power grid. As an innovative application of energy storage technology, mobile energy storage cabinets integrate battery technology, power electronics technology and intelligent control system, which can realize the storage, conversion and flexible allocation of electrical energy to meet the needs of emergency power supply, peak shaving and valley filling and off-grid power supply scenarios.

[0003] Mobile energy storage cabinets are commonly used for power supply in underground tunnels. When moving them, they may encounter long slopes, potentially leading to tipping over during transport. Therefore, CN215421170U discloses a mobile energy storage cabinet. By manually rotating a knob, a deceleration lever is driven to rotate, causing a deceleration plate to rotate and move away from a mounting slot. Once the deceleration plate is rotated to the ground, the handle is pulled to extend the deceleration block along its length, moving it towards a mounting slot until the deceleration insert is inserted into the socket, thus securing it. This prevents the cabinet from tipping over rapidly due to excessive downhill speed, which could damage the internal energy storage box.

[0004] The above solution improves friction during transportation to some extent, but it still has certain shortcomings. Firstly, the deceleration plate directly contacts the ground, resulting in excessive friction and making it prone to wear over time. Furthermore, when there are obstacles such as protruding stones on the ground, the deceleration plate is likely to collide with them during movement. This collision not only further exacerbates the damage to the deceleration plate but also reduces the stability of the entire cabinet during movement, increasing transportation risks. Secondly, this solution performs poorly when transporting uphill on slopes. Using a deceleration plate to increase friction significantly increases the thrust required, demanding greater physical strength from operators to push the cabinet, increasing transportation difficulty and labor intensity. Conversely, without a deceleration plate, slippage is likely on slopes, potentially causing the cabinet to lose balance and tip over, also damaging the internal energy storage boxes.

[0005] Therefore, the applicant proposed a mobile energy storage cabinet as a solution. Utility Model Content

[0006] This utility model provides a mobile energy storage cabinet that solves the problems mentioned in the background.

[0007] To solve the above-mentioned technical problems, this utility model provides a mobile energy storage cabinet, including a cabinet body, universal wheels installed at the four corners of the cabinet body, a translation wheel installed at the middle position of the bottom end of the cabinet body, and a transportation protection assembly installed inside the cabinet body. The transportation protection assembly includes two support plates fixed to the bottom end of the cabinet body. A first end face ratchet is rotatably installed on one side wall of the support plate. A second end face ratchet that can mesh with each other is provided on one side of the first end face ratchet. The second end face ratchet is fixed to one side of the telescopic rod. The telescopic rod slides inside the fixed cylinder. The second end face ratchet is connected to the fixed cylinder by a return soft spring. The fixed cylinder is fixed to the top of the moving plate. The moving plate is slidably connected to the bottom end of the cabinet body.

[0008] The top of the movable plate is equipped with a second support plate, and the second support plate is connected to one end of the telescopic rod by a strong spring that passes through the fixed cylinder.

[0009] The first end face ratchet teeth on both sides are in opposite directions, and the first end face ratchet rotates synchronously with the translation wheel through a synchronization component.

[0010] As a preferred technical solution of this utility model, two support plates three are fixed to the top of the movable plate, the fixed cylinder is inserted into the round hole of the support plate three, and one support plate three and support plate four are connected with two vertically aligned screws. The screws pass through the round hole of the support plate two and do not contact each other. The threaded part of the screw is threadedly connected to the threaded sleeve, and a stop block is fixed on the screw. The stop block and the threaded sleeve are respectively attached to the two sides of the support plate two.

[0011] As a preferred embodiment of this utility model, the support plate three and the support plate four are connected by two horizontally aligned guide rods, and the guide rods pass through the sliding holes of the support plate two to form a low-resistance sliding connection.

[0012] As a preferred technical solution of this utility model, the support plate is rotatably installed with a screw rod on the inner wall of the cabinet and is fixedly connected with a crossbar. The screw rod is threadedly connected to the movable plate, and the crossbar is slidably installed with the movable plate. The bottom of the movable plate is in contact with the bottom of the cabinet interior.

[0013] As a preferred embodiment of this utility model, the synchronization component includes a toothed pulley rotatably mounted between two support plates, a synchronization toothed belt wound around the toothed pulley, the synchronization toothed belt passing through the bottom of the cabinet, and a second toothed pulley wound around the lower end of the synchronization toothed belt, which is rotatably mounted at the bottom of the cabinet.

[0014] As a preferred embodiment of this utility model, a protective shell is installed at the bottom of the cabinet, and the second toothed pulley is rotatably installed on the inner wall of the protective shell. The shaft of the toothed pulley is connected to the connecting rods rotatably installed at both ends of the protective shell, and the connecting rods are connected to the wheel axle of the translation wheel for synchronous rotation.

[0015] As a preferred technical solution of this utility model, an energy storage rack is installed inside the cabinet, the transportation protection component is located in the space below the energy storage rack, and a glass plate is rotatably installed at the bottom of the cabinet. After the glass plate is rotated upward to a vertical position, it seals the space below the energy storage rack.

[0016] Compared with related technologies, the mobile energy storage cabinet provided by this utility model has the following beneficial effects:

[0017] 1. When this device is moving downhill, the second end ratchet on the corresponding end engages with the first end ratchet according to the transport direction. As the device moves downhill, the rotation of the translation wheel drives the first end ratchet to rotate through the synchronization component. The inclined surface of the first end ratchet's teeth presses against the inclined surface of the second end ratchet's teeth, causing the telescopic rod to compress the reset spring. At the same time, the strong spring is also compressed due to the relative movement of the second support plate, which can provide strong and stable resistance to the cabinet. This effectively prevents the cabinet from losing control due to the inertia of the downhill movement. It avoids the problems in the comparison document, such as the excessive friction between the deceleration plate and the ground causing wear and the cabinet becoming unstable due to collisions with protruding stones. This greatly improves the stability and safety of downhill transportation.

[0018] 2. Traditional mobile energy storage cabinets are prone to slipping, shifting back, or even tipping over when transported uphill. This device, however, first engages the ratchet on one end when going uphill. Then, instead of immediately moving the cabinet, the threaded sleeve on the screw is rotated away from the second support plate. At this point, when the telescopic rod moves, the powerful spring is no longer compressed, instead causing the second support plate to slide outside the guide rod. The reset spring only facilitates the reset of the telescopic rod and the ratchet on the second end face. This makes it much easier for operators to push the cabinet uphill, solving the slipping and shifting problem of traditional solutions, reducing the risk of tipping over, and ensuring safe and convenient uphill transportation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Depend on Figures 1-6 This utility model provides a mobile energy storage cabinet, including a cabinet body 1. Universal wheels 11 are installed at the four corners of the cabinet body 1, and a translation wheel 12 is installed at the center of the bottom of the cabinet body 1. A transport protection assembly 2 is installed inside the cabinet body 1. The transport protection assembly 2 includes two support plates 21 fixed to the bottom of the cabinet body 1. A first end-face ratchet 22 is rotatably mounted on the side wall of the support plate 21. A second end-face ratchet 23 that can mesh with each other is provided on one side of the first end-face ratchet 22. The second end-face ratchet 23 is fixed to a telescopic rod 24. On one side, the telescopic rod 24 slides inside the fixed cylinder 26. The second end ratchet 23 is connected to the fixed cylinder 26 and the return spring 25. The return spring 25 is wrapped around the outside of the telescopic rod 24. The fixed cylinder 26 is fixed to the top of the movable plate 27. The movable plate 27 is slidably connected to the bottom of the cabinet 1. The second support plate 28 is installed on the top of the movable plate 27. The second support plate 28 is connected to one end of the telescopic rod 24 and a strong spring 29 passes through the fixed cylinder 26. The first end ratchet 22 rotates synchronously with the translation wheel 12 through the synchronization assembly 3.

[0028] The synchronization component 3 includes a toothed pulley 31 rotatably mounted between two support plates 21. A synchronous toothed belt 32 is wound around the toothed pulley 31 and passes through the bottom of the cabinet 1. A second toothed pulley 31 is wound around the lower end of the synchronous toothed belt 32 and is rotatably mounted at the bottom of the cabinet 1. A protective shell 34 is installed at the bottom of the cabinet 1. The second toothed pulley 31 is rotatably mounted on the inner wall of the protective shell 34, and the shaft of the toothed pulley 31 is connected to a connecting rod 33 rotatably mounted at both ends of the protective shell 34. The connecting rod 33 is connected to the axle of the translation wheel 12 for synchronous rotation. The teeth of the first end face ratchet 22 on both sides are opposite, so the teeth of the second end face ratchet 23 are also opposite. That is to say, when both sides are engaged at the same time, the toothed pulley 31 cannot rotate, and the translation wheel 12 cannot rotate, thus locking. The protective shell 34 serves a protective function to prevent dust and small stones from affecting the operation.

[0029] The design of the transport protection component 2 and the synchronization component 3 features a ratchet with one end of its teeth being beveled and the other end being straight, a conventional design. During transport, the device utilizes four omnidirectional wheels 11 in conjunction with translation wheels 12. The omnidirectional wheels 11 facilitate steering, while the translation wheels 12 improve support, although they may introduce slight resistance to rotation, which is negligible. When transporting down a slope, depending on the transport direction, the second-end ratchet 23 on one side engages with the first-end ratchet 22. When the first-end ratchet 22 on this side rotates, its teeth are beveled and straight. When the first end face ratchet 22 rotates in the direction of the translation wheel 12, its inclined surface will also press against the toothed inclined surface of the corresponding meshing second end face ratchet 23. In specific operation, the moving plate 27 at this end is moved so that the second end face ratchet 23 at this end meshes with the first end face ratchet 22. When the four universal wheels 11 move to the ramp for downhill transport, the linkage 33 rotates together with the translation wheel 12, causing two of the first end face ratchet 22 to rotate through the toothed pulley 31 and the synchronous toothed belt 32, but the other first end face ratchet 22 is not meshed. The inclined surface of the teeth of the second end face ratchet 23 presses against the inclined surface of the teeth of the second end face ratchet 23, causing the telescopic rod 24 to slide into the fixed cylinder 26, compressing the return spring 25. At the same time, the strong spring 29 is also compressed due to the relative movement of the support plate 28. It should be noted that the strength of the strong spring 29 is much greater than that of the return spring 25. This gives the cabinet a strong and stable resistance when going downhill, effectively preventing the cabinet 1 from accelerating out of control due to the inertia of going downhill. When it is necessary to adjust the direction of movement of the cabinet 1 or to move normally on flat ground, simply disengage the meshing second end face ratchet 23 from the first end face ratchet 22 to release the braking state. When the transport direction is opposite, the ratchet on the other side can be engaged. After transporting to the designated position, the ratchet structures on both sides can be engaged together to lock the translation wheel 12. The principle is that when the ratchet teeth are engaged, the vertical edge of the teeth cannot rotate, that is, the telescopic rod 24 cannot move. Since the teeth of the first end face ratchet 22 on both sides are in opposite directions, when both first end face ratchet 22 are engaged, the first end face ratchet 22 cannot rotate clockwise or counterclockwise in one direction. Thus, the rotation of the translation wheel 12 is restricted by the synchronization component 3, thereby locking the cabinet 1.

[0030] Two support plates 212 are fixed to the top of the movable plate 27. The fixed cylinder 26 passes through the round hole of the support plate 212. One support plate 212 and support plate 213 are connected to two vertically aligned screws 215. The screws 215 pass through the round hole of the support plate 28, but do not contact each other. The threaded part of the screw 215 is threadedly connected to the threaded sleeve 217. The screw 215 is fixed with a stop block 216. The stop block 216 and the threaded sleeve 217 respectively fit against the two sides of the support plate 28. One support plate 212 and support plate 213 are connected to two horizontally aligned guide rods 214. The guide rods 214 pass through the sliding hole of the support plate 28 to form a low-resistance sliding connection.

[0031] Furthermore, under normal conditions, the abutment block 216 and the threaded sleeve 217 are respectively attached to the two sides of the support plate 28. When the telescopic rod 24 moves, it compresses the strong spring 29, providing good resistance when going downhill. However, when the cabinet moves uphill, the initial operation is the same as moving downhill, selecting the ratchet on the corresponding end. When moving upwards, the unidirectional rotation design of the first end ratchet 22 and the second end ratchet 23 can be utilized. However, the resistance provided by the strong spring 29 makes pushing upwards very difficult. Therefore, the solution is to not move the cabinet immediately after the ratchet on that end engages, and instead engage the screw 215... The threaded sleeve 217 rotates away from the support plate 28, so when the telescopic rod 24 moves, it will not compress the strong spring 29. Instead, the strong spring 29 will cause the support plate 28 to slide outside the guide rod 214. The reset soft spring 25 has less elasticity and only facilitates the reset of the telescopic rod 24 and the second end face ratchet 23 after they move. Specifically, when the threaded sleeve 217 is rotated away from the support plate 28, the support plate 28 is no longer constrained by the threaded sleeve 217. Since the strong spring 29 no longer provides additional resistance, the operator will feel much more relaxed when pushing the cabinet 1 up the slope. Once the cabinet 1 has been moved to the appropriate position, if it is necessary to lock the translation wheel 12 again or restore the resistance function of the strong spring 29, simply rotate the threaded sleeve 217 again so that it contacts and fits against the second support plate 28, and push the second support plate 28 to contact the stop block 216. This will fix the position of the second support plate 28, allowing the strong spring 29 to participate in the movement braking and locking process of the cabinet 1 again. Note that at this time, the strong spring 29 is in a slightly compressed state, that is, the second support plate 28 will not collide with the stop block 216 when sliding outside the guide rod 214, so that the mobile energy storage cabinet can better adapt to various complex usage environments.

[0032] The support plate 21 is rotatably installed with a screw rod 211 on the inner wall of the cabinet 1, and is fixedly connected with a crossbar 210. The screw rod 211 is threadedly connected to the movable plate 27, and the crossbar 210 and the movable plate 27 are slidably installed through each other. The bottom of the movable plate 27 is in contact with the bottom of the inside of the cabinet 1.

[0033] Furthermore, during engagement, a knob on one side of cabinet 1 (see...) Figure 1 and Figure 4 The point marked (a) drives the lead screw 211 to rotate, and the moving plate 27 can be moved under the limit of the crossbar 210, which is very convenient.

[0034] The cabinet 1 is equipped with an energy storage rack 13. The transport protection component 2 is located in the space below the energy storage rack 13. A glass plate 14 is rotated and installed at the bottom of the cabinet 1. After the glass plate 14 is rotated upward to be vertical, it seals the space below the energy storage rack 13. This is a conventional protection design technology.

[0035] The glass panel 14 design prevents dust from affecting the transport protection components 2 when the cabinet is opened, creating a closed space. The transparent design of the glass panel 14 also makes it convenient for staff to operate and view the equipment.

[0036] Working principle: When transporting the mobile energy storage cabinet downhill, firstly, according to the transport direction, select the second end ratchet 23 on the corresponding end face to engage with the first end ratchet 22. This provides strong and stable resistance to the cabinet 1 when going downhill, effectively preventing the cabinet 1 from accelerating out of control due to downhill inertia. When moving the cabinet 1 uphill, the initial operation is the same as moving it downhill. First, select the ratchet on the corresponding end to engage. Then, instead of moving the cabinet 1 immediately, rotate the threaded sleeve 217 on the screw 215 to prevent it from contacting the support plate 28 and move it away from it. This makes it much easier for the operator to push the cabinet 1 uphill. When adjusting the direction of movement of the cabinet 1 or moving it normally on flat ground, simply... Separate the second end ratchet 23 from the first end ratchet 22 to release the brake. If the transport direction is opposite, select the other ratchet to engage. After the cabinet 1 is transported to the designated position, the ratchet structures on both sides can be engaged together to lock the translation wheel 12. Note that the ratchet mechanism will also experience wear and slight noise during long-term operation, but in this case, it is only used when transporting uphill or downhill and will not collide with the outside world, such as rubbing against the ground, so it can be ignored and only requires regular maintenance. Although this case has many structures, it is very convenient to use. First, select the ratchet on one end to engage according to the transport direction, and then set the support plate 28 reasonably according to the uphill or downhill conditions. It also has a locking effect and is worth promoting.
