Description

Technical Field

[0001] This invention relates to the field of energy storage cabin frame technology, specifically to a quick-installation source-grid-load-storage energy storage cabin frame. Background Technology

[0002] The power generation-grid-load-storage system integrates power sources, grids, loads, and energy storage resources to achieve flexible regulation and stable operation of the power system. The energy storage compartment, as the core carrier of energy storage resources, places stringent requirements on the performance of its internal frame. Existing energy storage compartment frames suffer from the following key defects: 1. Installation and locking contradiction: Most quick-assembly frames use a single snap-fit ​​connection, and some only use wedge-shaped blocks to connect the support rod and the upright. They lack a secondary locking structure, and the snap-fit ​​is prone to loosening in a vibration environment. The connection locking force is less than 800N. On the other hand, frames that use bolts to assist in locking lose the advantage of quick assembly, and the installation efficiency is reduced by 40%.

[0003] 2. Poor adaptability and operability: The clamping of the support plate and the support rod is mostly of a fixed size, and the spacing cannot be finely adjusted according to the battery specifications. In addition, there is no guide structure when the wedge-shaped block is inserted into the socket, which requires repeated alignment and prolongs the installation time. The pressing rod has no reinforcement design and is prone to bending failure after long-term use.

[0004] 3. Insufficient durability: In outdoor scenarios, the frame is susceptible to corrosion. The salt spray resistance time of traditional galvanized coating is only 500 hours, and the gaps in mating parts such as sockets and pin holes are prone to increase due to wear, affecting the connection accuracy. Summary of the Invention

[0005] The technical problem this invention aims to solve is to overcome existing defects and provide a quick-installation energy storage module frame. Through the design of uprights, limiting brackets, tie rods, limiting blocks, support rods, wedge-shaped blocks, insertion holes, pressing rods, and springs, when connecting the uprights and support rods, both ends of the support rods are directly inserted into the insertion holes, and the tie rods are engaged in the limiting brackets via the limiting blocks. This accelerates the installation of the frame structure, improves construction efficiency, and effectively solves the problems in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quick-installation source-grid-load-storage energy storage cabin frame, comprising uprights, support rods, tie rods, and support plates, characterized in that: multiple sets of insertion holes are spaced apart along the height direction on the two opposite sides of the outside of the uprights, with two insertion holes symmetrically arranged in each set, and the inner wall of the insertion holes is provided with an inclined guide surface; a limiting bracket is fixedly provided on the other two opposite sides of the outside of the uprights, and two through pin holes are provided on the upper part of the limiting bracket, with an L-shaped pin with a limiting steel ball inserted into the pin hole; a limiting semi-ring is fixedly installed in the arc-shaped groove on the inner bottom side of the limiting bracket, and the inner wall of the limiting semi-ring is provided with anti-slip texture; The support rod has a hollow structure, and both ends of its inner side are rotatably connected to wedge-shaped blocks via pins.

A limiting ring is provided on the outer wall of the pin corresponding to the position of the steel ball, and the height of the steel ball protruding from the outer wall of the pin is 1.5mm-2mm.

[0009] The connection between the pressing rod and the wedge-shaped block is provided with reinforcing ribs, and the end of the pressing rod is provided with an anti-slip handle. The surface of the handle is provided with a mesh-like anti-slip texture with a texture depth of 1mm-1.2mm.

[0010] The spring is sleeved on a fixed post inside the support rod. The length of the fixed post is 2 / 3 of the free length of the spring, the pre-compression of the spring is 1 / 4 of its free length, and the elastic coefficient is 6N / mm-8N / mm.

[0011] The multi-position positioning holes of the locking groove are tapered holes with the diameter gradually increasing from the bottom to the opening of the groove. The taper is 1:5, and the spacing between the positioning holes is 50mm-100mm. The top of the elastic locking protrusion is a hemispherical structure with the diameter of the hemisphere matching the minimum diameter of the positioning hole. The extension stroke of the protrusion is 3mm-5mm, and the elastic coefficient of the built-in spring is 4N / mm-5N / mm.

[0012] The inner diameter of the limiting semi-ring is adapted to the outer diameter of the pull rod, with a gap of 0.5mm-1mm. The thickness of the limiting semi-ring is 8mm-10mm, and it is welded to the limiting seat, with a weld height of not less than 3mm.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention is based on the original upright 1, support rod 3, tie rod 4, support plate 2, wedge-shaped block 10, spring 12, pressing rod 11, L-shaped pin 14, limiting seat 7, and other parts, and through structural detail optimization, forms the following technical solution: (1) Core connection structure optimization Optimization of the connection between the upright and the support rod: The insertion hole 9 of the upright 1 is equipped with a 15° inclined guide surface (12mm in length), so that the support rod 3 does not need to be precisely aligned when inserted. The guide surface can guide the wedge-shaped locking block 10 to slide into the insertion hole automatically, reducing the alignment time from 15s / position to 7s / position. The end face of the wedge-shaped locking block is equipped with 35° barbed locking teeth (tooth height 2mm, spacing 3mm). After insertion, it forms a mechanical engagement with the inner side wall of the upright. With the help of the pre-compression spring (pre-compression amount 10mm, elastic coefficient 7N / mm), the connection locking force is increased from 800N to 1300N. Vibration test (frequency 5-50Hz, amplitude 2mm) for 2 hours showed no loosening.

[0021] Optimized locking of pull rod and limit seat: The L-shaped pin 14 has a contraction groove at the insertion end, and the limit steel ball protrudes 1.8mm. After being inserted into the pin hole 15, the steel ball is stuck into the pre-set annular groove on the hole wall, and the axial pull-out force is ≥150N, which is 50% higher than the original structure; the inner wall of the limit semi-ring 8 in the limit seat 7 is provided with anti-slip texture, which fits against the outer wall of the pull rod 4 to generate static friction. Combined with the anti-slip protrusions (1mm high) of the limit block 13 and the engagement of the groove texture, the double anti-loosening effect is significant.

[0022] (2) Operation and adaptability optimization Optimized pressing and disassembly: The connection between the pressing rod 11 and the wedge-shaped block is reinforced with a 5mm thick rib, which increases the bending strength by 60% and extends the service life from 500 insertions and removals to 1000 times; the textured anti-slip handle at the end (texture depth 1.1mm) can reduce the gripping force when pressing by 30%, making operation more effortless.

[0023] Support plate adaptation optimization: The locking groove 5 of the support rod 3 is equipped with a tapered positioning hole (taper 1:5, spacing 80mm), which is adapted to the hemispherical elastic locking protrusion (diameter 8mm) of the support plate 2. The protrusion has a telescopic stroke of 4mm, which can realize stepless micro-adjustment of the support plate spacing from 80mm to 1600mm. It is compatible with various specifications such as 18650 cylindrical batteries (spacing 18mm), 21700 cylindrical batteries (spacing 22mm), and square soft-pack batteries (spacing 50-100mm).

[0024] (3) Durability and protection optimization Material and coating optimization: All metal parts are made of Q235B steel, and the surface is treated sequentially with phosphate (thickness 6μm), hot-dip galvanizing (thickness 70μm), and fluorocarbon coating (thickness 25μm). After 1000 hours of salt spray corrosion test, there is no rust, which is 100% better than traditional coatings. The mating parts such as the insertion hole 9 and pin hole 15 are treated with high frequency quenching, with a surface hardness of HRC35-40 and wear of ≤0.1mm / 100 insertion and extraction cycles.

[0025] Clearance and fit optimization: The fit clearance between the limit block 13 and the groove of the limit seat 7 is 0.4mm, and the clearance between the limit half ring 8 and the pull rod is 0.8mm. This ensures smooth assembly and avoids wear caused by shaking, and the connection accuracy is maintained at ≤0.5mm over a long period of time.

[0026] The following is in conjunction with the appendix Figure 1-6 The embodiments of the present invention will be described in detail below, along with specific test data: 1. Preliminary preparations Parts inspection: Check that the dimensional deviation of parts such as upright 1 and support rod 3 is ≤ ±0.5mm, the barbed locking teeth of wedge block 10 are intact, the pre-compression of spring 12 is 10mm (free length 40mm), and the coating thickness meets the requirements (zinc plating layer 70μm±5μm).

[0027] Tools required: Only a level (accuracy 0.02mm / m) is needed; no special tools such as bolt wrenches are required, thus lowering the barrier to entry for operation.

[0028] 2. Pole positioning and installation Site positioning: Based on the dimensions of the energy storage compartment (10m long, 2.5m wide, and 2.2m high), mark the pole installation points on the ground with a horizontal spacing of 1.2m and a vertical spacing of 2.5m, and install a total of 9 poles.

[0029] Verticality adjustment of the pole: Place the pole vertically at the positioning point, visually align it initially, and use a level to measure the verticality of the pole. The error should be controlled within 0.5°. No additional fixing fixtures are required.

[0030] 3. Support rod installation (core quick-installation step) Guided insertion: Press the pressing rods 11 at both ends of the support rod 3 to compress the spring 12 to the end of the fixed column (compression amount 30mm), and the wedge-shaped locking block 10 is fully retracted; align the support rod with the insertion hole 9 of the upright 1, and push the support rod in without precise alignment by using the 15° guide surface of the insertion hole. The guide surface guides the wedge-shaped locking block to slide automatically to the insertion hole position, with a single alignment time of 6s.

[0031] Automatic locking: When the end face of the support rod is in contact with the upright, release the pressing rod, and the pre-compressed spring will quickly return to its original position (reset time 0.2s), pushing the barbed locking teeth of the wedge-shaped block into the inner wall of the upright. At this time, an axial tensile force of 1300N is applied, and the support rod shows no signs of slippage, completing the installation of a single support rod in ≤15s.

[0032] Multiple sets of support rods are installed at 0.5m, 1.0m, 1.5m and 2.0m along the height of the uprights. Each set has 4 rods (2 horizontal and 2 vertical). A total of 16 sets of support rods are installed on the 9 uprights. The total time is ≤4 minutes.

[0033] 4. Pull rod and anti-loosening lock Lateral tie rod assembly: Align the limiting blocks 13 at both ends of the tie rod 4 with the grooves of the limiting seat 7, apply a pressure of 40N to make the blocks fully embedded, and the grooves and the anti-slip texture of the blocks tightly engage to generate static friction force ≥300N.

[0034] Double locking pin: When the L-shaped pin 14 is inserted into the pin hole 15 of the limiting seat, the limiting steel ball is squeezed and contracted during the insertion process. After it is fully inserted, the steel ball pops out and gets stuck in the annular groove of the pin hole, with an axial pull-out force of 160N. The limiting half ring 8 fits against the outer wall of the pull rod, further limiting the radial sway of the pull rod. The assembly time of the double anti-loosening structure is ≤5s / location.

[0035] Full frame reinforcement: Each upright has a limit bracket with a tie rod installed. There are 16 horizontal tie rods and 8 vertical tie rods. The installation of all tie rods takes ≤3 minutes.

[0036] 5. Support plate and adapter adjustment Positioning of locking protrusions: Based on the spacing requirement of 21700 cylindrical batteries (22mm), the installation spacing of support plate 2 is calculated to be 220mm (10 sets of batteries are placed on each support plate). Align the elastic locking protrusion 6 on the lower side of the support plate with the third conical positioning hole of the locking groove 5 of the support rod (spacing 80mm, 3×80mm=240mm, after fine adjustment to fit 220mm).

[0037] Fine-tuning and locking: Press the hemispherical top of the elastic locking protrusion to retract it and lock it into the positioning hole. The built-in spring (elastic coefficient 4.5N / mm) provides continuous locking force. The support plate does not wobble after installation, the spacing error is ≤2mm, the installation time of a single support plate is ≤10s, and a total of 40 support plates are installed on a 10m frame, which takes ≤7 minutes.

[0038] 6. Performance Testing and Verification Installation efficiency test: A team of 3 people completed the installation of a 10m frame (including 9 uprights, 16 sets of support rods, 24 tie rods and 40 support plates) in 38 minutes, which is 31% shorter than the original quick-installation frame (55 minutes) and 79% shorter than the traditional bolt frame (180 minutes).

[0039] Locking and vibration test: A battery pack (24 packs, 50kg each) with a total weight of 1200kg was placed on the support plate, and the connection locking force test reached 1350N; after a 2-hour vibration test (frequency 5-50Hz, amplitude 2mm), all connection parts were not loose, and the barbed locking teeth of the wedge-shaped block were not deformed.

[0040] Compatibility and durability testing: Different battery specifications can be replaced and the support plate spacing can be adjusted to achieve stable placement, with 100% compatibility; after 1000 insertion and removal tests, the pressing rod did not bend, the wedge-shaped card block wear was 0.08mm, and the coating did not peel off; after 1000 hours of salt spray testing, the upright surface showed no rust, and the fitting accuracy of the insertion hole did not decrease.

[0041] 7. Disassembly process Disassembly of support plate: Press the hemispherical top of the elastic locking protrusion to disengage it from the conical positioning hole, slide the support plate out along the locking groove, and disassemble a single piece in ≤5s.

[0042] Pull rod removal: Press the limiting steel ball of L-shaped pin 14 to retract it out of the annular groove, pull out the pin (takes 2 seconds), apply a pulling force of 80N to remove the pull rod, and the removal time for a single rod is ≤8 seconds.

[0043] Disassembly of support rod: Press the pressing rods 11 at both ends of the support rod to compress the spring and cause the barbed locking teeth of the wedge-shaped block to disengage from the inner wall of the upright, and pull out the support rod (takes 10 seconds / rod).

[0044] Upright storage: Lay down the uprights one by one to complete the disassembly of the frame. The total disassembly time is ≤20 minutes. The disassembled parts can be stacked and stored, saving 30% of transportation space.

[0045] The technical advantages of this energy storage compartment frame are mainly reflected in enabling rapid assembly and disassembly, improving construction efficiency, and ensuring connection stability. Specifically, these advantages can be summarized in the following two points: 1. Significantly improves installation efficiency, enabling boltless quick installation. To address the slow installation speed caused by the reliance on bolted connections in existing energy storage module frames, this frame achieves efficient assembly through optimized structural design: When connecting the upright and the support rod, no bolts are needed. Simply insert both ends of the support rod into the insertion holes of the upright. The wedge-shaped blocks inside the support rod will automatically lock into the inside of the upright under the action of the spring, completing the quick positioning. When connecting the tie rod to the upright, the limit blocks at both ends of the tie rod can be directly inserted into the limit bracket groove of the upright, and then the L-shaped pin can be inserted to lock it, eliminating the tedious steps of bolt tightening. The support plate and support rod can be quickly connected by locking protrusions into locking grooves, without the need for additional fastening procedures.

[0046] The aforementioned structural design eliminates the need for specialized tools and bolts in frame installation, significantly accelerating frame construction and effectively improving construction efficiency.

[0047] 2. Ensure connection stability and prevent slippage after assembly. While enabling quick assembly, the frame ensures reliable connections through multiple structural designs: The wedge-shaped locking blocks at both ends of the support rod cooperate with the spring and the pressing rod to form an elastic self-locking mechanism after being inserted into the insertion hole, preventing the support rod from detaching from the upright. The limit block of the pull rod is compatible with the groove of the limit seat, and the L-shaped pin is positioned by the limit steel ball after being inserted into the pin hole, which further strengthens the connection between the pull rod and the upright and prevents loosening. The limiting semi-ring inside the limiting bracket can provide auxiliary support for the tie rod, enhancing the overall stability of the structure.

[0048] This combination of "quick snap-fit ​​+ pin locking" design simplifies the installation process while ensuring connection strength, guaranteeing that the frame can stably support energy storage batteries and other equipment.

[0049] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
