Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, and specifically to energy storage devices. Background Technology

[0002] In related technologies, existing energy storage devices typically involve opening the device's door and inserting sensors to detect internal air parameters such as temperature and humidity. However, this method significantly disrupts the internal environment of the energy storage device during detection, thereby drastically affecting the accuracy of air parameter readings. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an energy storage device that can reduce the impact of sensor detection on the internal environment of the energy storage device and increase the accuracy of the detection results.

[0004] The energy storage device according to a first aspect embodiment of the present invention includes:

[0005] Energy storage module;

[0006] The housing has an internal cavity for accommodating the energy storage module. The housing also has a clearance hole communicating with the cavity, which is adapted to allow a sensor for detecting air parameters within the cavity to pass through.

[0007] A seal is attached to the housing and covers the clearance hole, the seal being configured to be detachable from the housing.

[0008] The energy storage device according to the embodiments of this utility model has at least the following beneficial effects: When the sealing member is connected to the housing, it covers the clearance hole, thus isolating the receiving cavity from the outside world, thereby keeping the air parameters of the receiving cavity stable and ensuring the stability of the energy storage module during operation. When the sealing member is removed from the housing, the receiving cavity is connected to the outside world through the clearance hole, allowing the sensor to enter the receiving cavity through the clearance hole and detect the air parameters of the receiving cavity. This facilitates the understanding of the electrical environment inside the receiving cavity by the operator. Since the above detection process no longer requires opening the door, and the clearance hole through which the sensor passes is less likely to cause air exchange between the receiving cavity and the outside air, the electrical environment of the receiving cavity can also remain stable when the sensor is detecting, thereby enabling the sensor to obtain more accurate air parameters.

[0009] According to some embodiments of the present invention, the sealing element includes a sealing rod, which passes through the clearance hole and is interference-fitted with the clearance hole.

[0010] According to some embodiments of the present invention, the sealing rod is elastic, and the inner wall of the clearance hole can squeeze the outer periphery of the sealing rod to cause the sealing rod to produce an inward elastic deformation.

[0011] According to some embodiments of the present invention, the sealing element further includes a cover, which is located outside the housing and connected to the end of the sealing rod away from the receiving cavity. The cover abuts against the side wall of the housing away from the receiving cavity. On a projection plane perpendicular to the axial direction of the clearance hole, the projection of the outline of the clearance hole is a first projection, and the projection of the abutting surface of the cover abutting against the housing is a second projection. The second projection surrounds the first projection.

[0012] According to some embodiments of the present invention, the inner wall of the clearance hole is provided with a thread extending axially along the clearance hole, and the thread of the sealing rod is adapted to the thread of the inner wall of the clearance hole.

[0013] According to some embodiments of the present invention, the housing includes a housing body and a sealing ring. The housing body has an opening that communicates with the receiving cavity. The sealing ring is disposed in the opening and the interior of the sealing ring defines the clearance hole. The sealing element is detachably connected to the sealing ring.

[0014] According to some embodiments of the present invention, the sealing element is rotatably connected to the side wall of the housing away from the receiving cavity; one end of the sealing element away from the rotating shaft of the sealing element is configured to be detachable from the housing and can rotate relative to the housing in a direction away from the receiving cavity so that the clearance hole communicates with the outside.

[0015] According to some embodiments of the present invention, the sealing element includes a support platform and a cover plate. The support platform is slidably connected to the lower part of the inner wall of the clearance hole and also has a support surface for carrying articles. The cover plate is connected to the side of the support platform away from the receiving cavity. The support platform can slide in a direction away from the receiving cavity to make the clearance hole communicate with the outside.

[0016] According to some embodiments of the present invention, the clearance hole is inclined downwards along the direction away from the receiving cavity.

[0017] According to some embodiments of the present invention, the housing includes a shell portion and a door body, the shell portion and the door body together defining the receiving cavity, and when the door body is opened, the receiving cavity communicates with the outside; the door body has the clearance hole.

[0036] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0037] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. 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.

[0038] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0039] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0040] In the description of this utility model, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0041] In related technologies, with the promotion and utilization of new energy sources such as solar and wind power, energy storage technology has also developed. Energy storage devices are often used to store electrical energy so that the power grid can intelligently regulate the power. Energy storage devices store and release electrical energy through energy storage modules. In order to keep the electrical characteristics of the energy storage modules stable, it is also necessary to set up a shell around the energy storage modules to protect the electrical environment in which the energy storage modules are located, and to periodically measure the air parameters inside the shell.

[0042] Existing measurement methods require staff to open the door of the energy storage device before allowing sensors to enter the housing to collect data. However, since the door of the energy storage device is also used to allow the energy storage module to enter and exit, the opened door will cause the external environment to cause great interference to the internal environment of the housing. The air parameters such as humidity and temperature inside the housing will change, which will affect the sensor's detection results.

[0043] In view of this, please refer to Figures 1-3 As shown, this utility model proposes an energy storage device 10. Without departing from the inventive concept of this utility model, the energy storage device 10 of this utility model includes, but is not limited to, energy storage containers, energy storage cabinets, etc.

[0044] The energy storage device 10 of this utility model includes an energy storage module 100, a housing 200, and a sealing element 300.

[0045] Please refer to Figure 2 As shown, where Figure 2 Only the installation location of the energy storage module 100 in some embodiments is shown. The energy storage module 100 of this invention is used to store and release electrical energy. In some embodiments, the energy storage module 100 includes a battery assembly, an air-cooling assembly, and a control assembly. The control assembly can adjust the output power of the air-cooling assembly to ensure that the internal environment of the energy storage device 10 is maintained at a preset temperature, and can also control the charging and discharging of the battery assembly. It should be understood that the energy storage module 100 of this invention is not limited to the above-described form. Those skilled in the art can adjust the components of the energy storage module 100 themselves, and all such adjustments should be within the protection scope of this invention.

[0046] Please refer to Figure 2 , Figure 3 As shown, the housing 200 of this invention has an internal cavity 210 for accommodating the energy storage module 100. The housing 200 isolates the cavity 210 from the outside environment, thereby ensuring that the air parameters of the cavity 210 remain stable, and thus ensuring the stability of the energy storage module 100 during operation.

[0047] The housing 200 is provided with a clearance hole 220 communicating with the receiving cavity 210. The clearance hole 220 is adapted to allow a sensor for detecting air parameters inside the receiving cavity 210 to pass through. It should be noted that the phrase "the clearance hole 220 is adapted to allow a sensor for detecting air parameters inside the receiving cavity 210 to pass through" mentioned in this utility model should be understood as meaning that the aperture of the clearance hole 220 is large enough for a sensor for detecting air parameters inside the receiving cavity 210 to pass through, thereby allowing the sensor to enter the receiving cavity 210 through the clearance hole 220.

[0048] Exemplarily, in some embodiments, the housing 200 further includes a housing body 230 and a rectangular door 250. The housing body 230 has an opening communicating with the receiving cavity 210 for allowing people and the energy storage module 100 to enter and exit, and the outline of the opening is adapted to the shape of the door 250. When the door 250 is opened, the opening allows the receiving cavity 210 to communicate with the outside. The aperture size of the clearance hole 220 in the above embodiments can be 0.05-0.2 times the width of the door 250. In other embodiments, the aperture size of the clearance hole 220 can be 1.1-2 times the maximum size of the sensor perpendicular to its own length direction, or it can be 1-10 mm larger than the maximum size of the sensor perpendicular to its own length direction. The clearance hole 220 in the above embodiments can all allow the sensor to enter the receiving cavity 210 through the clearance hole 220. However, the present invention is not limited to the above embodiments. Without departing from the inventive concept of the present invention, those skilled in the art can also determine the aperture size of the clearance hole 220 according to other dimensions of the energy storage device 10 or the sensor.

[0049] Please refer to Figure 3 As shown, the sealing element 300 of this utility model is connected to the housing 200 and covers the clearance hole 220. The sealing element 300 is configured to be detachable from the housing 200. When the sealing element 300 is connected to the housing 200 and covers the clearance hole 220, the receiving cavity 210 is isolated from the outside, thereby keeping the electrical environment of the receiving cavity 210 stable and ensuring the stability of the energy storage module 100 during operation. When the seal 300 is removed from the housing 200, the receiving cavity 210 is connected to the outside through the clearance hole 220, so that the sensor can enter the receiving cavity 210 through the clearance hole 220 and detect the air parameters of the receiving cavity 210. This makes it easier for the staff to understand the electrical environment inside the receiving cavity 210. Since the above detection process no longer requires opening the door 250, and the clearance hole 220 through which the sensor passes is less likely to cause the air in the receiving cavity 210 to exchange with the outside air, the electrical environment of the receiving cavity 210 can remain stable when the sensor is measuring, thereby enabling the sensor to obtain more accurate air parameters.

[0050] On the other hand, since the seal 300 is also configured to be detachable from the housing 200, when the sensor detection ends, the seal 300 can also be removed from the outside of the housing 200 toward the direction closer to the receiving cavity 210 (e.g. Figure 2 , Figure 3 The right-hand side of the cavity 210 is reconnected to the housing 200, which can isolate the cavity 210 from the outside world again, thereby keeping the electrical environment of the cavity 210 stable and ensuring the stability of the energy storage module 100 during operation.

[0051] This invention does not limit the manner in which the seal 300 is detachably connected to the housing 200. As a preferred embodiment, please refer to... Figure 3 As shown, in some embodiments, the seal 300 includes a sealing rod 310, which passes through and is interference-fitted with the clearance hole 220. The sealing rod 310, interference-fitted with the clearance hole 220, seals the clearance hole 220, thereby isolating the receiving cavity 210 from the outside. Furthermore, the friction of the inner wall of the clearance hole 220 further keeps the seal 300 stationary when not removed, increasing the stability of the connection between the seal 300 and the housing 200. When it is necessary to disassemble the seal 300, the operator can apply force to the seal 300 by hand or with tools, causing the seal 300 to move in a direction away from the receiving cavity 210 (e.g., ...). Figure 3 The sealing rod 310 moves to the left (as shown in the diagram) so that it disengages from the clearance hole 220.

[0052] Based on the above embodiments, in some embodiments, the sealing rod 310 is elastic, and the inner wall of the clearance hole 220 can compress the outer periphery of the sealing rod 310 to cause the sealing rod 310 to undergo an inward elastic deformation. When the sealing rod 310 and the clearance hole 220 are interference-fitted, due to the inward elastic deformation of the sealing rod 310, the inner wall of the clearance hole 220 can fully contact the outer peripheral surface of the sealing rod 310, further enhancing the sealing effect of the sealing rod 310, further stabilizing the electrical environment of the receiving cavity 210, and enabling the sensor to obtain more accurate air parameters.

[0053] To make the sealing rod 310 elastic, it is made of an elastic material. This invention does not limit the material of the sealing rod 310. For example, the material used to make the sealing rod 310 can be EPDM rubber, thermoplastic elastomer, polyvinyl chloride, fluorinated polyethylene, etc.

[0054] Please refer to Figure 5 As shown, Figure 5This illustration shows a scenario where the seal 300 is detachably connected to the housing 200. In some embodiments, the housing 200 includes a housing body 230 and a sealing ring 240. The housing body 230 has an opening 231 communicating with the receiving cavity 210. The sealing ring 240 is disposed within the opening 231, and the interior of the sealing ring 240 defines a clearance hole 220. The sealing ring 240 is elastic, and the sealing rod 310 is interference-fitted with the clearance hole 220. Through this design, the sealing rod 310 can compress the sealing ring 240, allowing the inner wall of the clearance hole 220 to fully contact the outer peripheral surface of the sealing rod 310, further enhancing the sealing effect of the sealing rod 310 and further stabilizing the electrical environment of the receiving cavity 210. Furthermore, the elasticity of the sealing ring 240 reduces direct collision between the sensor and harder parts of the housing 200, protecting the sensor when it extends into the receiving cavity 210 via the clearance hole 220.

[0055] The relationship between the aperture size of the clearance hole 220 and the sensor size in some embodiments has been described previously. In embodiments where the housing 200 is provided with a sealing ring 240, the aperture size of the clearance hole 220 may be smaller than the maximum size of the sensor in the direction perpendicular to its own length. The sealing ring 240 will be compressed by the sensor, causing the aperture size of the clearance hole 220 to increase, allowing the sensor to enter the receiving cavity 210 through the clearance hole 220. The sensor will also be compressed by the sealing ring 240, thus being able to be fixed on the housing 200, further enhancing stability during the measurement process.

[0056] As a preferred option, please refer to Figure 4 As shown, Figure 4 This illustrates a scenario where the seal 300 is detachably connected to the housing 200. Figure 4 The thread 221 shown is for illustrative purposes only. In some embodiments, the inner wall of the clearance hole 220 is provided with a thread 221 extending axially along the clearance hole 220, and the thread of the sealing rod 310 is adapted to the thread 221 of the inner wall of the clearance hole 220. The sealing rod 310, adapted to the thread of the inner wall of the clearance hole 220, can seal the clearance hole 220, thereby isolating the receiving cavity 210 from the outside, and the thread 221 of the inner wall of the clearance hole 220 can further restrict the extension direction of the seal 300 along the clearance hole 220 (e.g., Figure 4 The seal 300 is moved (in the left-right direction shown in the diagram), thereby keeping the seal 300 stationary when not removed, increasing the stability of the connection between the seal 300 and the housing 200. When it is necessary to remove the seal 300, the operator can rotate the seal 300 by hand or with tools, so that the seal 300 moves in a direction away from the receiving direction (e.g., the left-right direction shown in the diagram). Figure 4 The sealing rod 310 moves to the left (as shown in the diagram) so that it disengages from the clearance hole 220.

[0057] Please refer to Figure 3 , Figure 5 As shown, in some embodiments, in addition to the sealing rod 310 provided in the sealing member 300, the sealing member 300 further includes a cover 320. The cover 320 is located outside the housing 200 and connected to the end of the sealing rod 310 away from the receiving cavity 210. The cover 320 abuts against the side wall of the housing 200 away from the receiving cavity 210. On a projection plane perpendicular to the axial direction of the clearance hole 220, the projection of the outline of the clearance hole 220 is the first projection, and the projection of the abutting surface of the cover 320 abutting against the housing 200 is the second projection. The second projection surrounds the first projection. Through the above scheme, the portion of the cover 320 abutting against the housing 200 can also restrict air from entering between the sealing member 300 and the inner wall of the clearance hole 220 along the radial direction of the clearance hole 220, further restricting the exchange of air between the external environment and the air in the receiving cavity 210. On the other hand, the cover 320 can restrict the sealing rod 310 connected to the cover 320 from further entering the receiving cavity 210 by its abutment relationship with the side wall of the housing 200 away from the receiving cavity 210. The reaction force of the side wall on the cover 320 can also indicate to the operator that the sealing rod 310 has been installed in the appropriate position inside the clearance hole 220.

[0058] As a preferred option, please refer to Figure 8 , Figure 9 As shown, Figure 8 , Figure 9 Different states of the seal 300 are shown. In some embodiments, the seal 300 is rotatably connected to the side wall of the housing 200 away from the receiving cavity 210. One end of the seal 300 away from the rotating shaft is configured to be detachable from the housing 200 and can rotate relative to the housing 200 in a direction away from the receiving cavity 210 to allow the clearance hole 220 to communicate with the outside. When the end of the seal 300 away from the rotating shaft is connected to the housing 200, the entire seal 300 can cover the clearance hole 220, thus isolating the receiving cavity 210 from the outside. When the end of the seal 300 away from the rotating shaft is detached from the housing 200, please refer to... Figure 9 As shown, the seal 300 is rotatable relative to the housing 200 in a direction away from the receiving cavity 210 (e.g., toward). Figure 8 , Figure 9 (With the paper as a reference, rotating clockwise) allows the receiving cavity 210 to connect to the outside through the clearance hole 220. Since the seal 300 remains rotatably connected to the housing 200, after the sensor completes the air parameter measurement, the operator can directly rotate the seal 300 again, causing the end of the seal 300 away from the rotation axis to reconnect to the housing 200, thus allowing the seal 300 to completely cover the clearance hole 220. The above embodiment makes it easier for the operator to adjust the opening and closing state of the clearance hole 220.

[0059] Without departing from the inventive concept of this utility model, those skilled in the art can design their own detachable connection method between the end of the seal 300 away from its own rotation axis and the housing 200. Exemplarily, in some embodiments, the seal 300 can be snap-fitted to the housing 200. In other embodiments, a magnet is provided at the end of the seal 300 away from its own rotation axis, and the surface of the housing 200 in contact with the seal 300 is provided with a ferromagnetic metal. Then, when the seal 300 covers the clearance hole 220, the magnet on the seal 300 attracts the ferromagnetic metal of the housing 200, allowing the seal 300 to be fixed to the housing 200.

[0060] Further, please refer to Figure 6 , Figure 7 As shown, Figure 6 , Figure 7 Different states of the seal 300 are shown. In some embodiments, the seal 300 includes a support platform 330 and a cover plate 340. The support platform 330 is slidably connected to the lower part of the inner wall of the clearance hole 220 and also has a support surface 331 for carrying articles. The cover plate 340 is connected to the side of the support platform 330 away from the receiving cavity 210. The support platform 330 can slide in a direction away from the receiving cavity 210 to allow the clearance hole 220 to communicate with the outside. The cover plate 340 can close the clearance hole 220, thus isolating the receiving cavity 210 from the outside. When it is necessary to insert a sensor through the clearance hole 220, the operator can pull the seal 300 in a direction away from the receiving cavity 210 (e.g., ...). Figure 6 , Figure 7 The device moves to the left (in the middle direction) to allow the clearance hole 220 to connect with the outside. Please refer to... Figure 7 As shown, when the seal 300 moves to a certain extent, the operator can place the sensor on the bearing surface 331 and then move the seal 300 in a direction closer to the receiving cavity 210 (e.g., Figure 6 , Figure 7 The cover plate 340 re-closes the clearance hole 220 by moving to the right (in the middle direction). Through the above scheme, the seal 300 seals the clearance hole 220 through the cover plate 340 while allowing the sensor to be placed into the clearance hole 220 or the receiving cavity 210 through the bearing surface 331. The receiving cavity 210 remains isolated from the outside world when the sensor detects air parameters, making the sensor's detection results more accurate.

[0061] Without departing from the inventive concept of this utility model, both the cover plate 340 and the sealing element 300 in the above embodiments can be designed to be detachably connected to the housing 200. For example, in some embodiments, when covering the clearance hole 220, the cover plate 340 can further enhance the sealing effect on the clearance hole 220 by means of magnetic attraction or snap-fit ​​connection. In other embodiments, the support platform 330 can slide in a direction away from the receiving cavity 210 to separate the sealing element 300 entirely from the housing 200. This allows the operator to place the sensor on the support platform 330 and then slide the support platform 330 onto the lower part of the inner wall of the clearance hole 220, making operation more convenient.

[0062] Please refer to Figure 5 As shown, in some embodiments, the housing 200 further includes a housing body 230 and a sealing ring 240. The housing body 230 has an opening 231 communicating with the receiving cavity 210. The sealing ring 240 is disposed within the opening 231, and the interior of the sealing ring 240 defines a clearance hole 220. The sealing member 300 is detachably connected to the sealing ring 240. The sealing member 300 is detachably connected to the housing 200 via the sealing ring 240. When the sealing ring 240 wears out during long-term use, those skilled in the art can separate the sealing ring 240 from the housing body 230 and install a new sealing ring 240 on the housing body 230 to maintain the sealing effect of the sealing member 300 on the clearance hole 220 and reduce maintenance costs.

[0063] Please refer to Figure 10 As shown, where Figure 10 The seal 300 is not shown. Furthermore, in some embodiments, the clearance hole 220 is inclined downwards along the direction away from the receiving cavity 210. With the above solution, water vapor accumulated on the side wall of the housing 200 will be less likely to enter the receiving cavity 210 through the clearance hole 220 due to its own gravity, effectively enhancing the waterproof performance of the energy storage device 10 and enhancing the working stability of the energy storage module 100.

[0064] Please refer to Figure 11 As shown, in some embodiments, a portion of the sidewall of the housing 200 is bent relative to another portion, such that the thickness direction of a portion of the sidewall slopes downward in a direction away from the receiving cavity 210 (e.g. Figure 11 The housing 200 has a portion of its surface facing downward to the left away from the receiving cavity 210. A clearance hole 220 is provided on the aforementioned portion of the side wall, and the extension direction of the clearance hole 220 is parallel to the thickness direction of the housing 200. This design enhances the waterproof performance of the energy storage device 10 and also facilitates the processing of the clearance hole 220.

[0065] Please refer to Figures 1-3As shown, further, in some embodiments, the housing 200 includes a housing portion 260 and a door body 250, which together define a receiving cavity 210. When the door body 250 is open, the receiving cavity 210 communicates with the outside. The door body 250 has a clearance hole 220. Through this solution, when the operator uses a sensor inserted into the clearance hole 220 for detection, they can simultaneously confirm the state of the door body 250, reducing the possibility that the door body 250 is still open when the sensor is used for detection, thereby reducing errors in the detection results.

[0066] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
