Energy storage system

Abstract

The invention relates to the field of energy storage equipment manufacturing, in particular to an energy storage system. Compared with a traditional energy storage system, the energy storage system has the advantages that the gear I rotates to drive the four racks I and the sliding blocks to move outwards and upwards at the same time, so that the four shells located on the upper portion are driven to be unfolded; and meanwhile, through the connecting device, when the upper shell is unfolded, the four lower shells can be driven to be unfolded, so that when the temperature is too high due to internal heat accumulation, the eight shells can be triggered to be unfolded outwards at the same time, air flow is increased, generated combustible gas rapidly escapes, and explosion is prevented. And meanwhile, when the corresponding shells in the vertical direction are separated, the powder barrel can be pushed inwards, then the fire extinguishing powder is added inwards, and internal combustion is further prevented.

Description

Technical Field

[0001] This invention relates to the field of energy storage equipment manufacturing, and more specifically to an energy storage system. Background Technology

[0002] Currently, with the development of society and the economy, energy storage systems, consisting of a housing and several battery modules housed within it, are widely used in electric vehicles, military equipment, and aerospace equipment. When a battery module experiences thermal runaway, to prevent the accumulation of flammable gas within the housing and subsequent explosion, the concentration of flammable gas inside the housing needs to be monitored in real time, and the gas must be promptly discharged outside the housing when the concentration reaches a set level. However, in traditional energy storage systems, the efficiency of flammable gas discharge from the housing is low during battery module thermal runaway, thus still posing a risk of explosion to the energy storage system. Summary of the Invention

[0003] The present invention provides an energy storage system, the purpose of which is to prevent the accumulation of combustible gases inside the energy storage system, to promptly discharge combustible gases, and to prevent explosions.

[0004] The above objectives are achieved through the following technical solutions:

[0005] An energy storage system includes a gear box I, on which four slide rails are fixedly connected, and a slider is slidably connected to each slide rail. A rack I is fixedly connected below each slider. A sleeve is rotatably connected inside the gear box I, passing through the gear box I. A gear I is fixedly connected below the sleeve, and the gear I meshes with the four racks I, which are arranged alternately in the vertical direction.

[0006] Four sliding rods are slidably connected to the gear box I, and a base plate is fixedly connected to the bottom of the sliding rods.

[0007] A screw is fixedly connected to the base plate, and the screw is threadedly connected to the sleeve that is rotatably connected to the gear box I; a gear II is fixedly connected to the top of the sleeve.

[0008] A cover is fixedly attached to the gear box I, and a round hole is provided on the cover. A spring box is fixedly attached below the round hole, and a rotating shaft is rotatably connected to the spring box. Gear III is fixedly attached below the rotating shaft, and gear III meshes with gear II.

[0009] A knob is fixedly connected above the rotating shaft, and a spring is fixedly connected between the spring barrel and gear III, with the spring sleeved on the outside of the rotating shaft.

[0010] The upper outer shell is fixedly connected to the corresponding slider, and a connecting device is fixedly connected between the two corresponding outer shells on the upper and lower sides.

[0011] The connecting device includes racks II and telescopic rods respectively fixed to the upper and lower outer shells. A gear box II is fixed between the two telescopic rods. A gear IV is rotatably connected inside the gear box II. The two racks II are slidably connected inside the gear box II and mesh with the gear IV.

[0012] The outer casing is provided with vents.

[0013] The outer shell has a notch, and a rotating plate is rotatably connected inside the notch. A baffle is rotatably connected between two corresponding rotating plates on the upper and lower sides. A powder cylinder is installed inside the corresponding two rotating plates and the baffle.

[0014] A frame is fixedly connected to the bottom of the base plate, and a battery is fixedly connected inside the frame; a support frame is fixedly connected to the bottom of the frame.

[0015] The beneficial effects of the energy storage system of the present invention are as follows:

[0016] Compared to traditional energy storage systems, this invention uses gear I to rotate, which simultaneously drives four racks I and sliders to move outward and upward, thereby unfolding the four upper outer shells. Simultaneously, a connecting device allows the unfolding of the upper shells to drive the unfolding of the four lower shells. This means that when internal heat buildup causes the temperature to become too high, all eight shells can be triggered to unfold outward simultaneously, increasing airflow and allowing flammable gases to escape rapidly, preventing an explosion. Furthermore, when the corresponding shells separate in the vertical direction, the powder cartridge can be pushed inward, adding extinguishing powder to further prevent internal combustion.

Detailed Implementation

[0032] refer to Figure 1-8 The diagram shows an embodiment of the present invention in which gear I105 drives four racks I104 to move:

[0033] Four slide rails 102 are fixedly connected to the gear box I 101. A slider 103 is slidably connected to each slide rail 102. A rack I 104 is fixedly connected below each slider 103. A sleeve is rotatably connected inside the gear box I 101. The sleeve passes through the gear box I 101. A gear I 105 is fixedly connected below the sleeve. The gear I 105 meshes with the four racks I 104. The four racks I 104 are arranged alternately in the vertical direction.

[0034] Gearbox I 101 provides mounting positions for four slide rails 102, which restrict the movement direction of sliders 103, allowing the four sliders 103 to move only along the slide rails 102 in the diagonal direction of battery 402. Sleeve allows gear I 105 to rotate within gearbox I 101, and gear I 105 can drive four racks I 104 to move simultaneously, thereby driving the four sliders 103 to move outward or inward simultaneously. The four racks I 104 are staggered in the vertical direction to prevent them from obstructing each other during movement.

[0035] refer to Figure 1-9 The diagram shows an embodiment of the present invention in which the gearbox I101 slides along the slide bar 108:

[0036] Four slide rods 108 are slidably connected to the gear box I 101, and a base plate 109 is fixedly connected to the bottom of the slide rods 108.

[0037] The four sliding rods 108 can restrict the gear box I 101 to move only in the up and down direction along the sliding rods 108, and can also prevent the gear box I 101 from rotating during the movement; the base plate 109 provides support for the four sliding rods 108 and the gear box I 101.

[0038] refer to Figure 1-9 The diagram shows an embodiment of the present invention in which the gear box I101 is driven to move up and down by the screw 107:

[0039] A screw 107 is fixedly connected to the base plate 109, and the screw 107 is threadedly connected to the sleeve that is rotatably connected to the gear box I 101; a gear II 106 is fixedly connected to the top of the sleeve.

[0040] The base plate 109 supports and fixes the screw 107; the screw 107 is threadedly connected to the sleeve, allowing the sleeve to move along the direction of the screw 107 when it rotates; this drives the gear box I 101 to move in the vertical direction; at the same time, gear I 105 drives the four racks I 104 to slide outward, thereby causing the four sliders 103 to move outward and upward simultaneously; gear I 105 and gear II 106 are respectively close to the upper and lower sides of gear box I 101, clamping gear box I 101, and at the same time, the rotation of gear II 106 drives the sleeve to rotate.

[0041] refer to Figure 1-10 The diagram shows an embodiment of the present invention in which gear II 106 is driven to rotate by gear III 115:

[0042] A cover 110 is fixedly connected to the gear box I 101. The cover 110 has a round hole. A spring box 111 is fixedly connected below the round hole. A rotating shaft 113 is rotatably connected to the spring box 111. A gear III 115 is fixedly connected below the rotating shaft 113. The gear III 115 meshes with the gear II 106.

[0043] The cover 110 can protect the inside of the gear box I 101; the spring box 111 can provide a mounting position for the shaft 113; the shaft 113 can rotate simultaneously with the gear III 115, and drive the gear II 106 to rotate through the meshing connection between the gear III 115 and the gear II 106.

[0044] refer to Figure 1-10 The diagram shows an embodiment in which the spring 114 keeps the gear III 115 rotating.

[0045] A knob 112 is fixedly connected above the rotating shaft 113, and a spring 114 is fixedly connected between the spring box 111 and the gear III 115. The spring 114 is sleeved on the outside of the rotating shaft 113.

[0046] The knob 112 is located above the spring box 111 and can drive the shaft 113 to rotate by turning it, thereby driving the gear III 115 to rotate. At the same time, turning the knob 112 can cause the spring 114 to store elastic potential energy and cause the gear III 115, as well as the gear I 105 and the gear II 106, to have a tendency to rotate, thereby causing the four sliders 103 to have a tendency to slide outward and move upward.

[0047] refer to Figure 1-4 The diagram illustrates an embodiment of the present invention in which the outer casing 201 is moved by the slider 103:

[0048] The four outer shells 201 located at the top and the four outer shells 201 located at the bottom are fixedly connected to the corresponding sliders 103, and the two outer shells 201 located on the upper and lower sides are fixedly connected by a connecting device.

[0049] The four upper outer shells 201 can move with the slider 103. When the spring 114 releases its elastic force, the four upper outer shells 201 can move outward and upward simultaneously to complete the unfolding function, increase the heat dissipation area and prevent the accumulation of internal gas and heat, thereby preventing explosion. The connecting device enables the four lower outer shells 201 to move with the four upper outer shells 201.

[0050] refer to Figure 1-12 The diagram illustrates an embodiment of the present invention in which the outer shells 201 located on the upper and lower sides are moved by a connecting device:

[0051] The connecting device includes racks II 202 and telescopic rods 203 respectively fixed to the upper and lower outer shells 201. A gear box II 204 is fixed between the two telescopic rods 203. A gear IV 205 is rotatably connected inside the gear box II 204. The two racks II 202 are slidably connected inside the gear box II 204 and mesh with the gear IV 205. At the same time, the outer shell 201 is provided with ventilation holes.

[0052] The telescopic rod 203 has an elongation tendency, thus ensuring that the gear box II 204 is always located at the center of the upper and lower outer shells 201. Simultaneously, when the upper outer shell 201 moves upward, the upper rack II 202 moves upward, driving the gear IV 205 to rotate, thereby driving the lower rack II 202 and outer shell 201 to move downward, causing the upper and lower outer shells 201 to move symmetrically relative to the center of the gear IV 205. When the invention uses a fuse-type temperature-sensing component to trigger the spring 114 to release its elastic force and drive the four upper outer shells 201 to move simultaneously outward and upward, the four lower outer shells 201 can also move simultaneously outward and downward, allowing all eight outer shells 201 to fully unfold, thus rapidly dissipating the accumulated heat. Ventilation holes on the outer shells 201 also allow for heat dissipation even when the eight outer shells 201 are in a retracted state.

[0053] refer to Figure 1-14 The diagram illustrates an embodiment of the present invention in which an internal open flame is extinguished using a powder cylinder 303:

[0054] The outer casing 201 has a notch, and a rotating plate 301 is rotatably connected inside the notch. A baffle 302 is rotatably connected between two corresponding rotating plates 301 on the upper and lower sides. A powder cylinder 303 is installed inside the corresponding two rotating plates 301 and baffle 302.

[0055] When the outer casing 201 on the upper and lower sides moves upward and downward respectively, it can pull the two rotating plates 301 to rotate inward, thereby pulling the baffle 302 to move inward, thus sending the powder cylinder 303 into the interior of the outer casing 20; at the same time, the rotating plates 301 in the front-back direction separate, thereby pulling the two powder cylinders 303 apart, thus releasing the calcium bicarbonate inside the powder cylinder 303 to achieve the purpose of extinguishing the fire; when the outer casing 201 is in the retracted state, the powder cylinder 303 can be used as a detachable fire extinguishing device.

[0056] refer to Figure 1-6 The diagram illustrates an embodiment of the present invention in which the battery 402 is protected by the frame 401:

[0057] A frame 401 is fixedly connected to the bottom of the base plate 109, and a battery 402 is fixedly connected inside the frame 401; a support frame 403 is fixedly connected to the bottom of the frame 401.

[0058] The frame 401 is located on the outside of the battery 402 and can support and protect the battery 402; the support frame 403 can fit completely with the four outer shells 201 located below, thereby enhancing the sealing of the outer shells 201 in the contracted state.
