Description

Technical Field

[0001] The present invention relates to the technical field of energy storage cabinets, and in particular to an intelligent protection device for an outdoor energy storage cabinet and a control method thereof. Background Art

[0002] Energy storage cabinet is a device used to store energy, usually through batteries and other energy storage elements, to store electricity when electricity is abundant or the price is low, and release electricity when the demand for electricity is peak or the price is high, thereby achieving time transfer and optimal use of electricity. It can be connected to the power grid, renewable energy power generation systems (such as solar photovoltaic, wind power generation, etc.) and various loads.

[0003] When energy storage cabinets are used outdoors, especially in areas with frequent sandstorms, they face the problem of sand and dust invasion. Therefore, it is necessary to protect the energy storage cabinets from sand and dust to prevent sand and dust from entering the cabinet and affecting the operation of the equipment. The traditional method mainly uses filters to protect and filter sand and dust, and improve the sealing effect of the cabinet to reduce the entry of sand and dust into the cabinet. However, while this approach ensures sand and dust protection, it also brings some shortcomings. First, the use of multi-layer filters will increase the wind resistance effect, thereby affecting the ventilation and heat dissipation effect of the cabinet. In addition, the improvement of sealing performance will also increase the temperature inside the cabinet, affecting the normal operation of the equipment. Therefore, when the energy storage cabinet is used outdoors, there is a contradiction between its sand protection and heat dissipation treatment. Summary of the invention

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships described in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] Reference Figure 1-Figure 14 , an intelligent protection device for an outdoor energy storage cabinet, comprising a wind direction and dust detection component 2 arranged on the top of the energy storage cabinet 1, a dust filter box 5 installed at the air inlet of the energy storage cabinet 1, an air outlet regulating box 6 installed at the exhaust port of the energy storage cabinet 1, and an air inlet regulating box 4 arranged on the side of the dust filter box 5, the wind direction and dust detection component 2 includes a wind direction detector and a dust detector, which are used to detect the wind direction and dust concentration, so as to judge the environment in which the energy storage cabinet 1 is located, and then adjust the vent positions of the air outlet regulating box 6 and the air inlet regulating box 4 according to the characteristics of the environment, and a protective baffle 3 is installed above the wind direction and dust detection component 2. And only the air outlet regulating box 6 is installed at the exhaust port because when exhausting, the air flow is discharged outward, and there is no need to deal with internal dust prevention, and it is only necessary to prevent external sand and dust from being directly blown into the air outlet regulating box 6.

[0021] The size and structure of the air inlet regulating box 4 and the air outlet regulating box 6 are the same, but their positions on the energy storage cabinet 1 are different. Here, the air inlet regulating box 4 is described in detail. One end of the air inlet regulating box 4 is open and connected to the inside of the sand and dust filter box 5. The middle part of the side of the air inlet regulating box 4 facing away from the open opening is provided with a first air port 401, and the other two symmetrical sides of the air inlet regulating box 4 are respectively provided with a second air port 402 and a third air port 403. The upper and lower heights of the three air ports are consistent, and dustproof grids are installed for preliminary treatment of large particles of sand and dust. The inside of the air inlet regulating box 4 Both sides are provided with air port blocks 7 for closing the second air port 402 and the third air port 403 respectively, and the two air port blocks 7 jointly control the closing of the first air port 403, the inner top of the air intake regulating box 4 is provided with a synchronous reverse driving component 8 and a one-way adjustment motor 10 connecting the two air port blocks 7, the inner bottom end of the air intake regulating box 4 is provided with a lifting connecting component 9 for connecting the two air port blocks 7, the inner upper end of the dust filter box 5 is provided with a plurality of filter screens 11, and the inner lower end of the dust filter box 5 is provided with a screw driving component 12 for driving the movement of each single filter screen 11. After detecting and determining the wind direction and dust concentration, the air outlet orientations of the air inlet regulating box 4 and the air outlet regulating box 6 can be adjusted to be staggered with the direction of the wind and sand. For example, when the detected wind direction corresponds to the first air outlet 401 and the sand and dust can be blown directly into the first air outlet 401, the two air outlet baffles 7 work to block and seal the first air outlet 401, and the second air outlet 402 and the third air outlet 403 are opened for ventilation to ensure the heat dissipation effect. The detected dust concentration corresponds to the number of filters 11 used, that is, the larger the concentration, the more filters 11 are used, and the smaller the concentration, the fewer filters 11 are used. This achieves dust filtering protection while minimizing the impact on ventilation and heat dissipation effects.

[0022] It also includes a controller and a temperature sensor arranged inside the energy storage cabinet 1. The controller is electrically connected to the wind direction and dust detection component 2, the temperature sensor, the synchronous reverse drive 8, the one-way adjustment motor 10 and the screw drive 12, and is used to adjust the synchronous reverse drive 8, the one-way adjustment motor 10 and the screw drive 12 to perform corresponding work according to the detected temperature, dust concentration and wind direction.

[0023] Further, in order to ensure that the air port stopper 7 can seal the first air port 401, the second air port 402 and the third air port 403, the position and structure of the air port stopper 7 are described in detail below: Reference Figure 3-Figure 11, L-shaped baffles are connected to the upper and lower ends of the interior of the air intake regulating box 4, and the air port baffle 7 is installed between the upper and lower L-shaped baffles, that is, the two L-shaped baffles are respectively arranged on the upper and lower sides of the first air port 401, and the air port baffle 7 includes a first rotating plate 71 and a second rotating plate 72, and the two sides of one end of the first rotating plate 71 are respectively fixedly connected with a rotating shaft 7103 and an outer prism 7104, and the rotating shaft 7103 and the outer prism 7104 are coaxial with the end of the first rotating plate 71, so that the first rotating plate 71 and the outer prism 7104 rotate around the rotating shaft 7103, and the rotating shaft 7103 is rotatably installed on one of the L-shaped baffles, and the second rotating plate 72 is U-shaped, and one end of the second rotating plate 72 is provided with a second through hole 7202 adapted to the rotating shaft 7103, and the other end of the second rotating plate 72 is provided with a first through hole sleeved on the outside of the outer prism 7104 Hole 7201, the rotating shaft 7103 is adapted to the second through-hole 7202, so that the second rotating plate 72 can rotate relative to the first rotating plate 71, and at the same time, there is a gap between the outer wall of the outer prism 7104 and the inner wall of the first through-hole 7201, and the synchronous reverse driving member 8 is movably connected to the two rotating shafts 7103, that is, the synchronous reverse driving member 8 can drive the two rotating shafts 7103 to rotate at the same time, and each unidirectional adjustment motor 10 is movably connected to a rotating shaft 7103, that is, when the synchronous reverse driving member 8 is not connected to the two rotating shafts 7103, each unidirectional adjustment motor 10 can drive a rotating shaft 7103 to rotate, and the lifting connecting member 9 connects the outer prism 7104 and the first through-hole 7201, and forms a card connection between the second rotating plate 72 and the first rotating plate 71, so that the first rotating plate 71 can drive the second rotating plate 72 to rotate at the same time.

[0024] Furthermore, when the first air port 401 is sealed, the first rotating plate 71 needs to be further designed. The first rotating plate 71 is hollow inside, and a first electric push rod 7102 and a sliding plate 7101 are arranged inside the hollow. When the two first rotating plates 71 are parallel, Fig. 9 As shown, the first electric push rod 7102 extends to make the two sliding plates 7101 extend out of the first rotating plate 71 and seal and block the first air port 401. At this time, the two extended sliding plates 7101 fit together.

[0025] When the first rotating plates 71 of the two air port stoppers 7 need to move in the opposite direction at the same time, the synchronous reverse driving member 8 is used for operation and control. The synchronous reverse driving member 8 is described in detail below: Reference Figure 3-Figure 11A sealed driving chamber 404 is formed between the top of the air intake regulating box 4 and the L-shaped partition. The synchronous reverse driving member 8 is installed in the driving chamber 404 to prevent wind and sand from entering. It includes a double-headed motor 81, a telescopic shaft 82 installed at both ends of the double-headed motor 81, and a bevel gear 84 installed at the end of the telescopic shaft 82 and the rotating shaft 7103. The bevel gear 84 on the telescopic shaft 82 is meshed with the bevel gear 84 on the rotating shaft 7103, and the telescopic shaft 82 is located on both sides of the double-headed motor 81. When the double-headed motor 81 rotates, the two telescopic shafts 82 are driven to rotate at the same time. Under the action of the bevel gear 84, the two rotating shafts 7103 rotate in opposite directions, thereby realizing that the two first rotating plates 71 rotate in opposite directions. The end of the telescopic shaft 82 away from the double-headed motor 81 is sleeved with a sliding bracket 83, which is used to ensure the stability of the telescopic shaft 82 during the overall rotation. A second electric push rod 85 is provided on one side of each sliding bracket 83, and the second electric push rod 85 drives the sliding bracket 83 to slide on the bottom wall of the driving chamber 404. When the double-headed motor 81 is needed to drive the two rotating shafts 7103 to rotate at the same time, the second electric push rod 85 extends, the telescopic shaft 82 unfolds, and the bevel gear 84 on the telescopic shaft 82 is meshed with the bevel gear 84 on the rotating shaft 7103. When the double-headed motor 81 is not needed to drive the two rotating shafts 7103 to rotate, the second electric push rod 85 contracts, the telescopic shaft 82 contracts, and the bevel gear 84 on the telescopic shaft 82 is disengaged from the bevel gear 84 on the rotating shaft 7103. After disengagement, during the process of the rotating shaft 7103 being driven to rotate by the one-way adjustment motor 10 alone, after each rotation is completed, it is necessary to reset first, and then the two bevel gears 84 are meshed to ensure the stability of the meshing.

[0026] When the synchronous reverse driving member 8 drives the rotating shaft 7103 to rotate, in order to avoid interference with the one-way adjustment motor 10, the one-way adjustment motor 10 is designed as follows: Specifically, a prismatic inner hole is opened at the end of the rotating shaft 7103, and a connecting rod matching the prismatic inner hole is installed at the end of the output shaft of the one-way adjustable motor 10, and a cylinder for driving the one-way adjustable motor 10 up and down is embedded in the top wall of the driving chamber 404. The cylinder contracts to move the one-way adjustable motor 10 upward, and the one-way adjustable motor 10 is disengaged from the rotating shaft 7103. The cylinder extends and the one-way adjustable motor 10 moves downward. The connecting rod on the output shaft of the one-way adjustable motor 10 is inserted into the rotating shaft 7103, and after each rotation of the rotating shaft 7103 driven by the synchronous reverse driving member 8, it can be ensured that the connecting rod on the output shaft of the one-way adjustable motor 10 is inserted into the rotating shaft 7103.

[0027] When the two rotating shafts 7103 rotate, that is, the first rotating plate 71 rotates, the second rotating plate 72 can rotate along with the first rotating plate 71, or the first rotating plate 71 can rotate alone, as follows: Reference Figure 3-Figure 13A sealed regulating chamber 405 is formed between the bottom of the air intake regulating box 4 and the L-shaped partition. The lifting connection member 9 is installed in the regulating chamber 405 to prevent dust from entering the regulating chamber 405. It includes a third electric push rod 91, a connecting plate 92 connected to the end of the third electric push rod 91, and a rotating sleeve 93 rotatably installed at both ends of the connecting plate 92. The third electric push rod 91 is embedded and fixed on the bottom wall of the regulating chamber 405. The third electric push rod 91 is retracted to drive the connecting plate 92 and the rotating sleeve 93 to move. The end of the rotating sleeve 93 away from the connecting plate 92 passes through the L-shaped partition and fits on the outer prism 7104, and the outer side of the rotating sleeve 93 is inserted in the first through hole 7201. When the third electric push rod 91 is extended, the connecting plate 92 and the rotating sleeve 93 move upward, and the end of the rotating sleeve 93 passes through the L-shaped partition and is inserted into the first through hole 7201. At the same time, the rotating sleeve 93 is sleeved on the outer prism 7104. At this time, the first rotating plate 71 rotates, and the outer prism 7104 rotates accordingly. The outer prism 7104 rotates, driving the rotating sleeve 93 to rotate on the connecting plate 92. The rotating sleeve 93 rotates and drives the second rotating plate 72 to rotate, so that the second rotating plate 72 rotates following the first rotating plate 71. When the third electric push rod 91 is retracted, the connecting plate 92 and the rotating sleeve 93 move downward, and the rotating sleeve 93 detaches from the first through hole 7201 and the outer prism 7104. At this time, the first rotating plate 71 rotates, and the outer prism 7104 rotates in the first through hole 7201 accordingly. Since there is a gap between the outer wall of the outer prism 7104 and the inner wall of the first through hole 7201 , the outer prism 7104 will not drive the second rotating plate 72 to rotate, and the rotating shaft 7103 rotates in the second through hole 7202 .

[0028] It should be noted that after adjusting the air inlet orientation of the air inlet regulating box 4 and the air outlet regulating box 6, when the sand concentration and the internal temperature of the energy storage cabinet 1 are detected, the number of filters 11 and the cleaning of the filters 11 can also be adjusted. The details are as follows: Reference Figure 3-Figure 14 The interior of the dust filter box 5 is divided into a filter chamber 51 at the upper end and a dust removal chamber 52 at the lower end by a horizontal partition. The filter chamber 51 corresponds to the open mouth of the air inlet adjustment chamber 405. The screw drive 12 covers the dust removal chamber 52 and the filter chamber 51, and the bottom of the horizontal partition is provided with a bottom slot for the filter screen 11 to pass through. A dust collector 13 for discharging dust to the outside of the dust filter screen 11 is provided at the bottom of the dust removal chamber 52. The filter chamber 51 is connected to the dust removal chamber 52 only through the bottom slot, and the filter screen 11 completely covers the bottom slot under normal circumstances to avoid the dust collector 13 directly acting on the filter chamber 51 when it is working. The dust collector 13 discharges the dust absorbed in the dust removal chamber 52 downward from the dust filter box 5 to avoid the accumulation of dust in the dust filter box 5 and reduce the intensity of manual processing.

[0029] At the same time, in order to enable multiple filters 11 to ensure better protection against sand and dust, the filter 11 includes a first filter 111, a second filter 112 and a third filter 113 which are arranged in sequence. The mesh openings of the first filter 111, the second filter 112 and the third filter 113 are increased in sequence, and the first filter 111 is located at one end close to the energy storage cabinet 1. For example, the first filter 111 is 500 mesh, the second filter 112 is 300 mesh, and the third filter 113 is 200 mesh. The dust can be protected and filtered according to usage requirements.

[0030] When the filter 11 is no longer needed in the filter chamber 51, the corresponding filter 11 is moved into the dust removal chamber 52 by the lead screw drive 12. Therefore, in the process of the filter 11 moving downward, the sand and dust adsorbed on the filter 11 can also be processed to cooperate with the vacuum cleaner 13 for dust removal. At the same time, when it is moved to the filter chamber 51 for use next time, its filtering and protection effect can be better. Therefore, a dust scraper 14 is provided on one side of the first filter 111, the second filter 112 and the third filter 113 on the top wall of the dust removal chamber 52. The dust scraper 14 is L-shaped, and bristles are provided on the horizontal bottom end of the dust scraper 14. The bristles of the dust scraper 14 are against the surface of the filter 11, and the inner side of the filter 11 is chamfered to make the scraped dust roll out of the filter 11, which is convenient for being absorbed by the vacuum cleaner 13.

[0031] Reference Figure 1-Figure 17 , a control method for an outdoor energy storage cabinet intelligent protection device, comprising the following steps: S1, firstly, the wind direction and dust concentration of the environment in which the energy storage cabinet 1 is located are detected by the wind direction and dust detector, and then the temperature inside the energy storage cabinet 1 is detected by the temperature sensor and transmitted to the controller; S2, after receiving the detected temperature, risk and dust concentration, the controller controls the synchronous reverse drive 8, the lifting connection 9, the screw drive 12 and the one-way adjustment motor 10 to adjust the air inlets of the air inlet adjustment box 4 and the air outlet adjustment box 6, and adjust the number of filters 11 at the same time.

[0032] Specifically, S201, when the wind and sand are strong, according to the direction of the wind and sand, the air inlet adjustment box 4 and the air outlet adjustment box 6 are adjusted to make the wind and sand direction opposite to the air outlet position, so as to prevent the wind and sand from directly entering the ventilation opening: like Fig. 9 As shown, when the wind direction is toward the first air inlet 401, the first air inlet 401 is closed, and the second air inlet 402 and the third air inlet 403 are opened; like Fig.15 As shown, when the wind direction is toward the second air port 402, the second air port 402 is closed, and the first air port 401 and the third air port 403 are opened; like Fig.16As shown, when the wind direction is toward the first air inlet 401 and the second air inlet 402, the first air inlet 401 and the second air inlet 402 are closed, and the third air inlet 403 is opened; like Fig.17 As shown, when there is no wind or the sandstorm is small, the first air port 401 , the second air port 402 and the third air port 403 are opened at the same time to accelerate the air flow in the air intake adjustment box 4 .

[0033] S202, when the temperature inside the energy storage cabinet 1 is high, rapid heat dissipation is required. If there is a lot of dust, multiple filters are started and the power of the cooling fan inside the energy storage cabinet 1 is increased; if there is little dust, only the third filter 113 is turned on to reduce ventilation resistance and improve ventilation effect.

[0034] S203, when the temperature in the energy storage cabinet 1 is low, if the wind and sand are strong, multiple filters 11 are started at the same time; if the wind and sand are light, only the third filter 113 is turned on, or all the filters 11 are moved into the dust removal chamber 52, S204, when the temperature inside the energy storage cabinet 1 is lower than the normal temperature and ventilation and heat dissipation are not required, the first air port 401, the second air port 402 and the third air port 403 are closed, and all the filters 11 are moved into the dust removal chamber 52 to remove dust from the filters 11.
