Description

Technical Field

[0001] This utility model relates to the field of electrical energy storage technology, specifically to an electrical energy storage device for black-start power supplies. Background Technology

[0002] Black start refers to a situation where the entire system shuts down due to a fault, resulting in a complete power outage (excluding isolated small power grids that may still be operating). The system is in a completely "dark" state and does not rely on other networks for assistance. Instead, it is started by generators with self-starting capabilities, which in turn drive generators without self-starting capabilities, gradually expanding the system's recovery range until the entire system is restored. In remote mountainous areas, photovoltaic black start is generally used. However, photovoltaic systems experience large current fluctuations due to weather conditions, so energy storage devices are needed to store the energy.

[0003] For example, Chinese Patent (Announcement No.: CN218940410U) discloses an energy storage power cabinet with multiple installation methods, including a cabinet body, mounting plate, control panel, fixing frame, fixing plate, bolts, nuts, fixing rods, and fixing blocks. This utility model has the following beneficial effects: the mounting holes facilitate the installation of the fixing plate on the ground and wall; the bolt output end and nut cooperation facilitate the installation of the cabinet body on the fixing frame, improving the stability of the device installed on the ground; the fixing rods, fixing blocks, and the gourd holes on the fixing frame facilitate the hanging of the cabinet body when the fixing plate is installed on the wall; and the external thread of the fixing rod and the threaded hole cooperation facilitate the storage of the fixing rods and fixing blocks when the cabinet body is installed on the ground.

[0004] However, the device has poor heat dissipation. Due to changes in temperature, voltage, etc., the battery temperature may rise. If the battery temperature rises too high, the battery life may be reduced, affecting the subsequent power supply for black start. Therefore, an energy storage device for black start power supply is proposed to solve the above problems. Utility Model Content

Multiple fan blades are fixed on the outer surface of the rotating rod. A support ring is fixed to the top of the housing. A dust cover is snapped onto the top of the housing and outside the support ring.

[0008] Furthermore, the base is concave in shape, and the inner wall of the base is located below the multiple air vents.

[0009] Furthermore, the support frame includes a support block fixed to the bottom wall of the inner cavity of the box, a stabilizing plate fixed to the top of the support block, a battery rack fixed to the top of the stabilizing plate, a battery pack fixed to the inner side of each of the battery racks, and a vent pipe fixed to the inner side of each battery rack.

[0010] Furthermore, a vent hole is provided on the top of the battery rack, and the vent hole is connected to a vent pipe, which extends into the stabilizing plate and is flush with the bottom of the stabilizing plate.

[0011] Furthermore, the support block is provided with a main exhaust port and multiple auxiliary exhaust ports, and the main exhaust port is connected to the vent pipe.

[0012] Furthermore, both the top of the housing and the top of the protective cover are provided with annular snap-fit ​​grooves, and both snap-fit ​​grooves are adapted to the dust cover.

[0013] Furthermore, the top of the protective cover is conical, and the bottom of the protective cover is fixed to the support ring.

[0014] Furthermore, each of the unidirectional components includes a baffle plate fixed to the inner wall of the vent, with a valve fixed to the end of the baffle plate away from the support frame.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] This energy storage device for black-start power supplies features a heat dissipation mechanism that blows relatively cool outside air into the housing to effectively cool the battery.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 This embodiment of an energy storage device for a black-start power supply includes a housing 1, a base 2 fixed to the bottom of the housing 1, a support frame 3 at the bottom of the inner cavity of the housing 1 to ensure ventilation and battery stability, the support frame 3 to fix the battery and improve overall stability, a heat dissipation mechanism 4 at the top of the housing 1 to continuously dissipate heat from the inside of the housing 1, a protective cover 5 fixed to the top of the heat dissipation mechanism 4, and multiple air vents on the left and right side walls of the housing 1 to allow airflow, each air vent containing a one-way component 6.

[0023] In addition, the base 2 is concave in shape. The concave base 2 can isolate the mud to a certain extent and ensure the overall stability of the device. The inner wall of the base 2 is located below multiple air vents. The inner wall of the base 2 being located below multiple air vents can ensure that the hot air inside the box 1 can be discharged smoothly and that the air circulation path remains unobstructed.

[0024] It should be further explained that the support frame 3 includes a support block 301 fixed to the bottom wall of the inner cavity of the housing 1. A stabilizing plate 302 is fixed to the top of the support block 301. The stabilizing plate 302 can improve the stability of the device. A battery rack 303 is fixed to the top of the stabilizing plate 302. A battery pack is fixed to the inner side of each of the multiple battery racks 303. A vent pipe 304 is fixed to the inner side of the battery rack 303. When air circulates in the vent pipe 304, it can carry away the heat on the pipe wall of the vent pipe 304.

[0025] It is known that the top of the battery rack 303 is provided with a vent hole, which is connected to the vent pipe 304. The heat inside the battery rack 303 is transferred to the vent pipe 304 and then to the outside through the vent pipe 304. The vent pipe 304 passes through the stabilizing plate 302 and is flush with the bottom of the stabilizing plate 302. The support block 301 is provided with a main exhaust hole and multiple auxiliary exhaust holes. The main exhaust hole is connected to the vent pipe 304.

[0026] In this embodiment, the vent pipe 304, in conjunction with the main exhaust port and the auxiliary exhaust port, can quickly transfer hot air to the outside. The combination of unobstructed airflow path and airflow driven by the heat dissipation mechanism 4 can significantly improve the overall heat dissipation effect.

[0027] Please see Figure 1 and Figures 2 to 3 To ensure heat dissipation, the heat dissipation mechanism 4 in this embodiment includes a servo motor 401 fixed to the side wall of the inner cavity of the protective cover 5. The output shaft of the servo motor 401 is fixed with a rotating rod 402. Multiple fan blades 403 are fixed on the outer surface of the rotating rod 402. The rotation of the multiple fan blades 403 can drive the air to circulate quickly. A support ring 405 is fixed on the top of the box 1. The support ring 405 can provide support force. Multiple air inlets are opened on the support ring 405. A dust cover 404 is snapped onto the top of the box 1 and outside the support ring 405. The dust cover 404 can allow air to circulate and filter the air at the same time.

[0028] Furthermore, both the top of the housing 1 and the top of the protective cover 5 are provided with annular snap-fit ​​grooves. The snap-fit ​​grooves can snap the dust cover 404 in place to prevent the dust cover 404 from moving left or right. Both snap-fit ​​grooves are adapted to the dust cover 404. The top of the protective cover 5 is conical, and the bottom of the protective cover 5 is fixed to the support ring 405.

[0029] In addition, each unidirectional component 6 includes an isolation plate 601 fixed to the inner wall of the vent, and a valve 602 is fixed to the end of the isolation plate 601 away from the support frame 3. The valve 602 is made of soft rubber.

[0030] In this embodiment, the device blows the air from above to below through the heat dissipation mechanism 4, and then exhausts the air through the one-way component 6. When not in use, the one-way component 6 can effectively prevent external dust, insects, etc. from entering the housing 1.

[0031] It is understandable that the device uses the heat dissipation mechanism 4 and the support frame 3 to promote rapid airflow and achieve efficient heat dissipation. Then, the dust cover 404 and the one-way component 6 work together to prevent external impurities from entering the box 1 and ensure the stability and safety of the box 1.

[0032] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0033] The working principle of the above embodiments is as follows:

[0034] When heat dissipation of the battery is required, simply start the servo motor 401 on the heat dissipation mechanism 4. The servo motor 401 drives the fan blades 403 on the rotating rod 402 to rotate. Outside air enters the housing 1 through the dust cover 404. Some air passes through the outside of the support frame 3, carrying away the heat around the support frame 3, and is discharged to the outside through the one-way component 6. The other part of the air passes through the vent pipe 304, carrying away the heat inside the battery rack 303, and is discharged to the outside through the one-way component 6. This device has a good heat dissipation effect and can ensure that the battery in the housing 1 has a stable and good working environment.

[0035] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
