Description

Technical Field

[0001] This utility model relates to a sealing device, and more particularly to a sealing device for a through-hole of a liquid-cooled energy storage container. Background Technology

[0002] Compared to traditional thermal and hydropower, renewable energy generation, represented by solar and wind power, exhibits randomness and volatility, leading to frequency issues on the power grid. Power disturbances cause increased frequency fluctuations, resulting in weak voltage support, poor disturbance rejection, and resonance between power generation equipment and the system. To address these problems, adding energy storage systems to the renewable energy generation side can effectively resolve these issues affecting the power grid.

[0003] According to national standards, the minimum IP protection level for energy storage containers is IP54, and the service life is no less than 20 years. This places high demands on the overall sealing and sealing materials of energy storage containers.

[0004] Currently, after the energy storage containers are assembled, fireproof putty is used to seal the through holes in the partition walls between adjacent compartments (such as battery compartments and liquid cooling compartments). When using fireproof putty to seal through holes, (1) First, ensure good ventilation in the work area and wear appropriate protective equipment, such as gloves and masks, to prevent harmful substances from coming into contact with the skin and respiratory system. (2) Clean the surface: Before applying fireproof putty, clean the surface to be sealed to ensure it is dry, free of oil and impurities. This helps to improve the adhesion and effect of the fireproof putty. (3) Mix the fireproof putty: If the fireproof putty is a two-component material, it is necessary to mix components A and B correctly according to the instructions. Ensure that the mixture is evenly mixed and avoid lumps or insufficient mixing. Apply the fireproof putty: Use an appropriate tool (such as a scraper or trowel) to evenly apply the fireproof putty to the surface to be sealed. Be careful to fill all gaps and holes to ensure that nothing is missed. (4) Curing time: Fireproof putty usually requires a certain amount of time to cure. According to the specific product instructions, wait enough time to ensure that it achieves the best protective effect. During this period, avoid touching or moving the applied fireproof putty. (5) Inspection and testing: After curing, check whether the fireproof putty completely covers all areas that need to be sealed. The entire operation process is complicated and the pipes are not easy to install after installation. Moreover, the sealing is not tight, making it difficult to achieve IP54 protection. Therefore, it is necessary to develop a new sealing device suitable for the wall penetration holes of the energy storage battery compartment. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a wall hole sealing device for a liquid-cooled energy storage container that is simple in structure, easy to install, aesthetically pleasing, and has strong sealing performance.

[0006] This utility model discloses a wall-penetrating hole sealing device for a liquid-cooled energy storage container. The device is characterized by comprising a fixing component, a sealing component, and a fastening component. The fastening component includes a first fastening component and a second fastening component. The fixing component has a first through hole and a second through hole. Two sealing components are provided, respectively mounted on the first through hole and the second through hole via the first fastening component. Each sealing component is fitted with a second fastening component.

[0007] This utility model discloses a through-hole sealing device for a liquid-cooled energy storage container, wherein the fixing component is a fixing plate with multiple through holes, and the through holes are provided with fixing parts for fixing the fixing plate.

[0008] This utility model discloses a through-hole sealing device for a liquid-cooled energy storage container, wherein the fastener for fixing the fixing plate is a blind hole waterproof rivet nut.

[0009] This utility model relates to a sealing device for the through-hole of a liquid-cooled energy storage container, wherein the fixing plate is an aluminum alloy plate.

[0011] This utility model discloses a sealing device for the through-hole of a liquid-cooled energy storage container, wherein the first fastening component and the second fastening component are both hose clamps.

[0012] The difference between this utility model and the prior art is that this utility model uses blind hole waterproof rivet nuts to fix the fixing plate to the wall between the liquid cooling chamber and the energy storage chamber. Then, two rubber sealing sleeves are respectively fitted onto the connecting protrusions of the first through hole and the second through hole of the fixing plate and fixed with hose clamps. The liquid inlet pipe and liquid outlet pipe of the liquid cooling unit in the liquid cooling chamber pass through the two rubber sealing sleeves and the first through hole and the second through hole, respectively, and enter the energy storage chamber where the battery pack is installed. After the liquid inlet pipe and liquid outlet pipe are installed in the energy storage chamber, the two rubber sealing sleeves are fixed to the liquid inlet pipe and liquid outlet pipe respectively with hose clamps.

[0013] The wall-penetrating hole sealing device of the liquid-cooled energy storage container of this utility model has at least the following beneficial effects:

[0014] (1) This through-wall sealing device has a simple structure and is easy to install, which simplifies the assembly process of liquid-cooled containers and improves processing efficiency.

Detailed Implementation

[0026] like Figure 1 , 3As shown in Figures 5 and 6, the present invention discloses a wall-penetrating hole sealing device for a liquid-cooled energy storage container 04, comprising a fixing component 01, a sealing component 02, and a fastening component 03. The fastening component 03 includes a first fastener 31 and a second fastener 32. The fixing component 01 is provided with a first through hole 111 and a second through hole 112. The liquid-cooled energy storage container 04 is provided with an energy storage compartment 41 and a liquid-cooled compartment 42. The fixing component 01 is installed on the wall 43 between the liquid-cooled compartment 42 and the energy storage compartment 41, and the first through hole 111 and the second through hole 112 correspond to the first wall-penetrating hole and the second wall-penetrating hole on the wall 43, respectively. There are two sealing components 02, which are respectively set on the first through hole 111 and the second through hole 112 through the first fastening component 31. Each sealing component 02 is fitted with a second fastening component 32. The liquid inlet pipe 44 and the liquid outlet pipe 45 of the liquid-cooled unit are respectively inserted into the two sealing components 02 and fixed by the two second fastening components 32.

[0027] The liquid-cooled energy storage container 04 is equipped with an energy storage compartment 41 for installing batteries and a liquid-cooled compartment 42 (liquid-cooled compartment 42 is on the left) for installing liquid cooling units. The liquid-cooled compartment 42 is separated from the energy storage compartment 41 by a partition (i.e., wall 43). The wall 43 has a first through-wall hole and a second through-wall hole for the liquid cooling unit's inlet pipe 44 and outlet pipe 45 to pass through the two through-wall holes and enter the energy storage compartment 41 to cool the batteries in the energy storage compartment 41. The fixing component 01 is fixed to the wall 43 with bolts. The two through-wall holes correspond one-to-one with the two through holes. In order not to occupy the volume of the energy storage compartment 41 and to ensure the safety of the energy storage compartment 41, the fixing component 01 is installed on... Inside the liquid cooling chamber 42, the right ends of the two sealing components 02 are firmly fixed to the first through hole 111 and the second through hole 112 of the fixing component 01 by the first fastening component 31, respectively. The left ends of the two sealing components are located inside the energy storage chamber 41. The liquid inlet pipe 44 and the liquid outlet pipe 45 pass through the sealing component 02, the through hole (first through hole 111 or second through hole 112), and the wall through hole (first wall through hole or second wall through hole) from the liquid cooling chamber 42 in sequence, and enter the energy storage chamber 41. After the liquid inlet pipe 44 and the liquid outlet pipe 45 are installed in the energy storage chamber 41, the left ends of the two sealing components 02 are finally firmly fixed to the liquid inlet pipe 44 and the liquid outlet pipe 45 by the two second fastening components 32, respectively.

[0028] With this configuration, the two through-wall holes are sealed tightly by the fixing component 01 and the sealing component 02, completely separating the energy storage chamber 41 and the liquid cooling chamber 42. Liquid and dust in the liquid cooling chamber 42 cannot enter the energy storage chamber 41, and dust and liquid in the energy storage chamber 41 cannot enter the liquid cooling chamber 42. This sealing device is not only simple in structure and easy to install, but also dustproof, waterproof and more aesthetically pleasing. If the temperature of the energy storage chamber 41 is too high or an accident such as a fire occurs, it can also play a role in heat insulation and fire prevention.

[0029] like Figure 1 ,2 As shown in Figure 4, the fixing component 01 is a fixing plate 11 with multiple through holes 114, and the through holes 114 are provided with fasteners for fixing the fixing plate 11.

[0030] The fixing component 01 is a flat fixing plate 11. The shape of the fixing plate 11 is not particularly limited. It can be rectangular, circular or other shapes. Its thickness is also not particularly limited. It can meet the usage requirements of the liquid-cooled energy storage container 04. The fixing plate 11 has multiple through holes 114. The fixing plate 11 is installed on the wall 43 between the liquid-cooled compartment 42 and the energy storage compartment 41 by fasteners passing through the through holes 114 to ensure that the fixing plate 11 will not loosen or fall off.

[0031] like Figure 3 , 5 As shown, the fastener for fixing plate 11 is a blind hole waterproof rivet nut (not shown in the figure).

[0032] By utilizing the robustness of the blind hole waterproof rivet nut, the stability and strength of the sealing device structure are effectively guaranteed. Its excellent waterproof performance ensures stability during long-term use, preventing rapid failure due to time, environmental factors, or other factors, thus effectively extending the service life of the fixing plate 11 and the overall liquid-cooled energy storage container structure. Furthermore, the installation process is relatively simple, requiring no complex processing or pre-reserved installation space. Connection is completed simply by inserting the rivet nut into the blind hole and using a special tool for riveting, improving installation efficiency and reducing installation costs.

[0033] like Figure 1 As shown, the fixing plate 11 is an aluminum alloy plate.

[0034] To ensure the waterproof, dustproof, and fireproof performance of the liquid-cooled energy storage container 04, the fixing plate 11 is made of a special aluminum alloy material. It can also be covered with a fireproof, waterproof, and highly insulating epoxy layer to further enhance the overall performance of the liquid-cooled energy storage container 04 and ensure that it meets the national standard of IP54 protection level.

[0035] IP54 specifically means that the dustproof rating is level 5 (protects against dust, but it cannot completely prevent dust from entering, but the amount of dust entering will not affect the normal operation of the equipment) and the waterproof rating is level 4 (prevents water splashing from all directions from entering the equipment and causing damage).

[0036] like Figure 1 , 2 As shown, the sealing component 02 is a rubber sealing sleeve 21. A connecting boss 113 is provided at both the first through hole 111 and the second through hole 112. The rubber sealing sleeve 21 is fitted on the connecting boss 113. The first fastening component 31 and the second fastening component 32 are both hose clamps 33.

[0037] A connecting boss 113 is provided at the first through hole 111 and the second through hole 112 on one side of the fixing plate 11. The other side of the fixing plate 11, i.e. the right side, is tightly attached to the wall 43 between the energy storage compartment 41 and the liquid cooling compartment 42 and is firmly fixed by a blind hole waterproof rivet nut. The rubber sealing sleeve 21 is a conical sealing sleeve, i.e., one end has a larger diameter than the other end. The larger diameter end of the two rubber sealing sleeves 21, i.e. the right end, is respectively fitted onto the two connecting bosses 113 and is fastened by a hose clamp 33. After the liquid cooling unit's inlet pipe 44 and outlet pipe 45 are installed by passing through the two rubber sealing sleeves 21, the smaller diameter end of the rubber sealing sleeve 21, i.e. the left end, is then fastened to the inlet pipe 44 and outlet pipe 45 respectively by the hose clamp 33 to ensure the sealing of the wall penetration hole of the liquid cooling energy storage container 04 and meet the national standard of IP54 protection level.

[0038] The length and diameter of the rubber sealing sleeve 21 are not specifically limited here. It can be matched with the through hole on the wall 43 according to the actual situation. Its material can be fluororubber, EPDM rubber or silicone rubber with dustproof, waterproof and fireproof properties. On the one hand, it can ensure that its protective performance meets the standards, and on the other hand, it can greatly extend the service life of the sealing device.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
