Description

Technical Field

[0001] This application relates to the field of energy storage system technology, specifically to a ventilation device and energy storage equipment. Background Technology

[0002] In applications such as photovoltaic power plants and wind power plants, the power generation curve and the grid load curve can differ significantly. Therefore, energy storage systems are typically provided to store and regulate electrical energy, ensuring system reliability and stability. Current energy storage systems, such as lithium-ion battery energy storage systems, usually employ a prefabricated container design for ease of production, installation, maintenance, and rapid deployment. To protect the electrical and electronic components within the energy storage system, the container's ventilation system must prevent the ingress of foreign objects such as dust and water; therefore, a high Ingress Protection (IP) rating is usually required, such as at least IP54.

[0003] In existing technologies, although the filters of ventilation devices can block dust, long-term use can lead to dust accumulation and clogging of the mesh, increasing air resistance and affecting equipment performance or lifespan, requiring frequent filter replacement. Cleaning or replacing the filter requires disassembling the entire ventilation device, incurring significant time costs and resulting in low efficiency in filter cleaning and maintenance. Utility Model Content

[0014] In one embodiment, the ventilation device further includes louvers, the ventilation opening extends through the mounting frame along a first direction, and the louvers and the filter are respectively disposed on both sides of the mounting frame in the first direction;

[0015] The louver includes a frame and multiple blades. The frame is connected to the mounting frame. The multiple blades are spaced apart on the frame along a second direction. The first direction intersects the second direction. Two adjacent blades form an air duct, which is connected to the ventilation opening.

[0016] In one embodiment, the window frame is detachably connected to the mounting frame by screws.

[0017] In one embodiment, the blade includes a first folding portion, a second folding portion, a third folding portion, and a fourth folding portion connected in sequence. The third folding portion extends along the second direction, and the tilt angles of the first folding portion relative to the second direction, the tilt angles of the fourth folding portion relative to the second direction, and the tilt angles of the second folding portion relative to the second direction gradually increase.

[0018] In one embodiment, in the second direction, the distance between the third folding portions of two adjacent blades is 22mm to 27mm.

[0019] In one embodiment, the ventilation device further includes a waterproof pad connected between the mounting frame and the window frame, the waterproof pad being arranged circumferentially around the ventilation opening.

Detailed Implementation

[0034] The following are specific embodiments of this application, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments.

[0035] This application provides an energy storage device, including a housing and a ventilation device. The housing has an opening connecting the interior and exterior of the housing, and the ventilation device is connected to the housing. The housing, as the main structure of the energy storage device, provides installation space and protection for various energy storage components and related electrical components inside. The opening provides an airflow channel for the ventilation device, allowing fresh air from outside to enter the housing and carry away the heat generated by the energy storage components and electrical components during operation, thereby reducing the internal temperature of the housing and preventing damage from overheating.

[0036] refer to Figure 1 , Figure 2 and Figure 3 This application provides a ventilation device, including a mounting frame 100, a filter element 200, and a locking assembly 300.

[0037] The mounting frame 100 is the basic support structure of the entire ventilation system. The mounting frame 100 is connected to the housing of the energy storage device, and its shape is a frame that can form a ventilation opening 110. The ventilation opening 110 is used to communicate with the opening of the housing to realize the circulation of air between the inside and outside of the housing.

[0038] The filter element 200 is detachably connected to the mounting frame 100 and is disposed in the opening of the housing. The filter element 200 is placed over the vent 110 to filter the air passing through the vent 110, removing dust, impurities, and harmful particles to improve air quality. The filter element 200 is a breathable dustproof component and can use filter media such as wire mesh or foam. It is connected to the mounting frame 100 via an edge fixing structure.

[0039] The locking assembly 300 includes a first locking seat 310, a second locking seat 320, and a locking member 330. The first locking seat 310 is fixed to the mounting frame 100, and the second locking seat 320 is fixed to the filter element 200. The second locking seat 320 has a locking groove 321. One end of the locking member 330 is rotatably connected to the first locking seat 310, and the other end of the locking member 330 is engaged in the locking groove 321. Specifically, the first locking seat 310 provides a mounting base for the locking member 330. The rotating end of the locking member 330 can be rotated via a hinge or a pivot 311. The engaging end can be designed as a hook or a protruding structure to form a limiting fit with the corresponding locking groove 321. By rotating the locking member 330, the locking member 330 can be engaged and disengaged from the locking groove 321, thereby facilitating the locking and unlocking operations of the filter element 200.

[0040] In this application, the filter element 200 is detachably connected to the mounting frame 100 and secured by a locking assembly 300. When the filter element 200 needs cleaning, replacement, or maintenance, simply operate the locking assembly 300 to rotate the locking member 330 out of the locking groove 321 of the second locking seat 320, and the filter element 200 can be easily removed from the mounting frame 100. After maintenance or replacement, the filter element 200 is then reinstalled onto the mounting frame 100 and locked by the locking assembly 300. The operation is simple and convenient, improving maintenance efficiency. The locking assembly 300 enables quick assembly and disassembly of the filter element 200 and the mounting frame 100, eliminating the need to disassemble or replace the entire ventilation device when cleaning or replacing the filter element 200, thus improving maintenance efficiency and reducing maintenance costs.

[0041] The design of the locking assembly 300 allows the filter element 200 to be securely fixed to the mounting frame 100. The first locking seat 310 and the second locking seat 320 are respectively fixed to the mounting frame 100 and the filter element 200. The locking member 330 engages with the locking groove 321 of the second locking seat 320 by rotation, forming a stable connection structure. This effectively prevents the filter element 200 from loosening, shifting, or falling off during use due to airflow or other external forces, ensuring the normal operation of the ventilation device and the filtration effect.

[0042] In this embodiment, multiple locking assemblies 300 are provided, and these multiple locking assemblies 300 are spaced apart in the circumferential direction of the ventilation opening 110. Specifically, when the filter element 200 needs to be fixed, the locking members 330 in the multiple locking assemblies 300 respectively engage with the locking grooves 321 on the corresponding second locking seats 320, forming a multi-point locking structure distributed circumferentially. Because the locking assemblies 300 are spaced apart, multiple edge areas of the filter element 200 are constrained, avoiding deformation caused by local stress concentration. During disassembly, the filter element 200 can be separated from the mounting frame 100 simply by releasing the locking state of each locking assembly 300 in sequence, without having to remove the entire ventilation device.

[0043] The mounting frame 100 includes a first side beam 120, a second side beam 130, a third side beam 140, and a fourth side beam 150 connected end to end. The first side beam 120, the second side beam 130, the third side beam 140, and the fourth side beam 150 form a ventilation opening 110. Three locking assemblies 300 are provided, and the first locking seat 310 of the three locking assemblies 300 is respectively provided on the first side beam 120, the second side beam 130, and the third side beam 140. One side of the filter element 200 abuts against the first side beam 120, the second side beam 130, and the third side beam 140, and the fourth side beam 150 is provided with a baffle 151 extending into the ventilation opening 110, and the baffle 151 abuts against the other side of the filter element 200.

[0044] The mounting frame 100 can be constructed using aluminum alloy profiles welded together or bolted together. The first side beam 120, the second side beam 130, the third side beam 140, and the fourth side beam 150 are connected end to end to form a closed frame. Three locking assemblies 300 are distributed on three adjacent side beams to form multi-point fixation. The baffle 151 is a limiting structure extending perpendicular to the fourth side beam 150, which can be made of bent steel plate or injection-molded flange, and is used to provide reverse support during the installation of the filter element 200.

[0045] During installation, the filter element 200 first contacts the positioning surfaces of the three side beams, and then the baffle 151 of the fourth side beam 150 automatically restricts its displacement, forming a four-point positioning constraint. By replacing the latch on the fourth side with the baffle 151, the operation steps are simplified, effectively shortening the replacement time of the filter element 200; at the same time, the guiding effect of the baffle 151 simplifies the installation and positioning process.

[0046] refer to Figure 2 , Figure 4 and Figure 5The ventilation device also includes louvers 400, and an air vent 110 extends through the mounting frame 100 along a first direction X. The louvers 400 and the filter element 200 are respectively disposed on both sides of the mounting frame 100 along the first direction X. The louvers 400 include a frame 410 and multiple blades 420. The frame 410 is connected to the mounting frame 100, and the multiple blades 420 are spaced apart on the frame 410 along a second direction Y. The first direction X intersects the second direction Y, and two adjacent blades 420 form an air duct 430, which communicates with the air vent 110. The louvers 400 are a grille structure with airflow guiding and protective functions. The first direction X can be perpendicular to the plane of the mounting frame 100, and the second direction Y can be horizontal or vertical.

[0047] Specifically, the louvers 400 are configured on the air inlet side of the mounting frame 100, forming a separate structural layout with the filter element 200. When air flows through the louvers 400, the blades 420 guide the airflow into the air duct 430 at a specific angle. By adjusting the spacing and tilt angle of the blades 420, a laminar flow effect can be achieved. The vent 110 is arranged through the thickness direction of the mounting frame 100, allowing the louvers 400 and the filter element 200 to respectively perform the functions of blocking foreign objects and filtering dust. The window frame 410 is fixed to the mounting frame 100 through an edge connection structure. Multiple blades 420 are arranged equidistantly along the length of the window frame 410, and the relative positions of adjacent blades 420 form a continuous airflow channel. The louvers 400 can be disassembled individually for cleaning and maintenance without removing the entire ventilation system.

[0048] In one embodiment, the mounting frame 100 and the window frame 410 are detachably connected by screws 500. During installation, the window frame 410 and the corresponding positions of the mounting frame 100 are first aligned, and then the screws 500 are passed through the mounting frame 100 and screwed into the threaded holes of the window frame 410 to fix them in place. During disassembly, the connection can be released by rotating the screws 500 in the opposite direction, at which point the window frame 410 can be removed separately from the mounting frame 100. Partial disassembly can be performed when maintaining or replacing the louvers 400, without having to disassemble the entire ventilation system.

[0049] The blade 420 includes a first folding section 421, a second folding section 422, a third folding section 423, and a fourth folding section 424 connected in sequence. The third folding section 423 extends along the second direction Y. The tilt angles of the first folding section 421, the fourth folding section 424, and the second folding section 422 relative to the second direction Y gradually increase. The first folding section 421 is the part of the blade 420 near the installation position on the window frame 410, and can be formed by stamping a bent section from sheet metal. Its tilt angle variation is used to adjust the airflow direction. The second folding section 422 is a transition section connecting the first folding section 421 and the third folding section 423, and its tilt angle variation is used to guide the airflow smoothly. The third folding section 423 is the main body section extending along the second direction Y to improve the support strength of the blade 420. The fourth folding section 424 is a guide section located at the end of the blade 420, and its tilt angle variation is used to control the airflow direction.

[0050] Specifically, when the airflow passes through the duct 430 formed by adjacent blades 420, the airflow passes sequentially through the fourth fold 424, the third fold 423, the second fold 422, and the first fold 421 of the blades 420. The gradient change in the tilt angle of each fold causes the airflow to form a laminar flow state within the duct 430, avoiding the generation of vortices due to abrupt changes in angle.

[0051] In the second direction Y, the distance L between the third folds 423 of two adjacent blades 420 is 22mm to 27mm. Specifically, the distance L between the third folds 423, which are extensions of the blades 420, is limited to 22mm to 27mm. Within this range, the air duct 430 formed between adjacent blades 420 ensures sufficient ventilation, reduces wind resistance, and improves waterproofing.

[0052] The ventilation device also includes a waterproof gasket 600, which is connected between the mounting frame 100 and the window frame 410, and is arranged circumferentially around the vent 110. Specifically, the waterproof gasket 600 is elastically deformed by the pressure generated by the screws 500 during tightening, thereby filling the assembly gap between the two. When external moisture penetrates along the joint surface between the louver 400 and the mounting frame 100, the continuous annular structure of the waterproof gasket 600 can block the water flow path, preventing moisture from entering the device and improving the waterproof effect.

[0053] The ventilation device also includes a panel 700, which is connected to the side of the window frame 410 away from the mounting frame 100. The panel 700 has multiple through holes 710. The panel 700 refers to a plate-like structure covering the outside of the louvers 400, which can be made by stamping metal sheets to prevent large external particles from directly impacting the blades 420, while maintaining airflow channels through the through holes 710. The through holes 710 are perforated structures penetrating the surface of the panel 700, and can be arranged in circular, rectangular, or irregular shapes. This arrangement effectively blocks the intrusion of foreign objects such as leaves and flying insects, while balancing protective performance with ventilation efficiency, avoiding excessive airflow resistance from the panel 700.

[0054] Specifically, panel 700 is welded to window frame 410 at its edge, forming a stable connection between panel 700 and louver 400. Panel 700 is located on the outer side of the windward side of louver 400, so that external airflow must first pass through the air duct 430 formed by through hole 710 and multiple blades 420 before entering filter element 200, thus forming a multi-stage filtration structure in the airflow path.

[0055] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0057] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0058] Furthermore, the technical solutions of the various embodiments of this application can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them.
