[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the technical solutions in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 15 The present invention provides a technical solution: a microgrid distributed new energy storage device, comprising an organic box 1, an air inlet 2 is opened at one end of the machine box 1, and a fan mechanism 4 is arranged at the air inlet 2, an air outlet 3 is opened at the other end of the machine box 1, a battery 5, two rows of symmetrically distributed switches 6 for adjusting ventilation, an air inlet baffle 7 blocked at one end of the switch 6, an exhaust baffle 8 blocked at the other end of the switch 6, and an integrated component 9 for driving the switch 6 are arranged in the machine box 1, the battery 5 is distributed between the two rows of switches 6, a first square cavity space is reserved in the machine box 1 between the exhaust baffle 8 and the air outlet 3, and the air inlet baffle 7 is provided between the two rows of switches 6. A second square cavity space for a built-in fan mechanism 4 is reserved in the machine box 1 between the air inlet 2, and a battery 5 is distributed between the air inlet baffle 7 and the air exhaust baffle 8. The integrated component 9 includes a two-way power tool 10, a belt tool 11, a brake unit 12 and a temperature measuring device 13. Both sides of the two-way power tool 10 are transmission-connected with the belt tool 11. A row of brake units 12 are arranged on one side of each belt tool 11, and each brake unit 12 is correspondingly connected to a switch 6. A temperature measuring device 13 for detecting the temperature is correspondingly arranged at each of the two heat dissipation surfaces on the battery 5, and the temperature measuring device 13 and the belt tool 11 are transmitted through contact.

[0035] refer to Figure 5It is understood that the switch 6 includes a concave folding frame 15, an air inlet plate 16 fixed at one end of the concave folding frame 15, and an exhaust plate 14 fixed at the other end of the concave folding frame 15, the air inlet baffle plate 7 and the exhaust baffle plate 8 are of the same shape, and both are long plates with two symmetrically distributed long holes, a row of exhaust plates 14 block the long holes on the exhaust baffle plate 8, and a row of air inlet plates 16 block the long holes on the air inlet baffle plate 7, and the brake unit 12 and the exhaust plate 14 are transmission connected.

[0036] There is airflow scraped on the two heat dissipation surfaces of the battery 5, and one end of the heat dissipation surface is opposite to the strip holes on the air inlet baffle plate 7, and the other end is opposite to the strip holes on the exhaust baffle plate 8. The fan mechanism 4 is a fan blowing mechanism in the prior art. The fan mechanism 4 works so that external air is sucked into the machine box 1, passes through the strip holes on the air inlet baffle plate 7 and then flows to the strip holes on the exhaust baffle plate 8. In the process, it scrapes across the heat dissipation surface of the battery 5, thereby taking away heat, and ventilating and cooling the battery 5. Finally, the hot air flow passes through the strip holes of the exhaust baffle plate 8 and is discharged through the air outlet 3. The present invention divides the relative strip holes of the air inlet baffle plate 7 and the exhaust baffle plate 8 into a plurality of unit plate hole channels through a row of switches 6, for example, referring to Fig. 9 , the exhaust plate 14 and the air inlet plate 16 supported by the concave folding frame 15 rise and fall synchronously, the exhaust plate 14, the concave folding frame 15 and the air inlet plate 16 form a switch 6, in the upper row of switches 6, the switch 6 at one end rises, then the switch 6 falls, and the adjacent switch 6 rises and falls again, and the cycle ends. A heat dissipation airflow with an unchanged direction but a changed route will flow between the air inlet baffle plate 7 and the air exhaust baffle plate 8. This heat dissipation airflow will scrape across the heat dissipation surface of the battery 5, and the heat dissipation airflow will also scan the heat dissipation surface of the battery 5 along the vertical direction of the airflow. Compared with the direct large-area heat dissipation and ventilation when there is no row of switches 6 distributed between the air inlet baffle plate 7 and the air exhaust baffle plate 8, the airflow is The heat dissipation ventilation area is large and the power is lost. If the heat dissipation is performed on a large area, in order to ensure the ventilation strength of the airflow, the fan mechanism 4 needs to work at a high load, so that the energy consumption naturally increases, and the energy saving demand is not met. The impact strength of the airflow is not enhanced, and the heat dissipation cannot be effectively and quickly dissipated. The present invention only has local airflow blowing for heat dissipation each time, which can effectively concentrate the airflow, so that the airflow ventilation intensity is increased, and the fan mechanism 4 does not need to work at a high load. At the same time, the strong airflow is scanned and blows across the heat dissipation surface of the battery 5. The heat dissipation surface of the battery 5 can be swept by the strong airflow at all places, and there will be no area with weak ventilation close to the heat dissipation dead corner. The ultimate goal is to make the heat dissipation surface of the battery 5 fully ventilated and heat dissipated.

[0039] refer to Figure 8 It is understood that the temperature measuring device 13 includes a horizontal frame 26, a T-shaped limit plate 27, a pull-back spring 28, a flat frame 29, a deformable rod 30 and a concave elastic clip 31. The flat frame 29 includes a horizontal plate and a row of L-shaped columns fixed on the horizontal plate.

[0040] refer to Fig.11It is understood that the flat plate portion 21 includes a roller 32, a movable plate 33, a reset spring 34 and a swimming block 35. The guide long plate 22 and the movable plate 33 are distributed perpendicular to each other, and the guide long plate 22 and the movable plate 33 slide through the two plate holes opened on the swimming block 35 respectively. One end of the reset spring 34 is fixed on the movable plate 33, and the other end is fixed on the swimming block 35. Both ends of the movable plate 33 support rollers 32. The closed-loop toothed belt 23 is inserted into the groove opened on the swimming block 35 by setting a rubber block. The T-shaped limit plate 27 is contacted with the roller 32 at one end of the movable plate 33 by setting a convex arc surface, and the roller 32 at the other end of the movable plate 33 is contacted with the brake unit 12 for transmission.

[0041] refer to Fig.12 It is understood that the brake unit 12 includes a T-shaped push body 37, a sub-frame 38, an axis group 39, a unit rack 40 and a pendulum body 43. One end of the sub-frame 38 is fixed on the exhaust baffle plate 8, and the other end of the sub-frame 38 is slidably inserted into the slide groove provided on the T-shaped push body 37 through a fixed T-column. One end of the axis group 39 is transmission connected to the T-shaped push body 37, and the other end is transmission connected to the pendulum body 43. The pendulum body 43 is transmission connected to the unit rack 40 by setting an arc-shaped rack, and one end of the unit rack 40 is fixed on the exhaust plate 14.

[0042] The brake unit 12 also includes an L-shaped slow rod 36, an air cylinder 41 and an air valve 42. One end of the L-shaped slow rod 36 is fixed on the exhaust plate 14, and the other end is slidably inserted into one end of the air cylinder 41. The other end of the air cylinder 41 is sealed with an air valve 42, and the air cylinder 41 is fixed on the sub-frame 38.

[0043] refer to Fig.13 It is understood that the shaft group 39 includes a unit vertical shaft 44, a mainspring 45, a sub-frame 46, a unit transverse shaft 47 and a pressure gear 48. The T-shaped push body 37 is connected to the pressure gear 48 by a row of teeth. One end of the unit vertical shaft 44 is fixed in the middle of the pressure gear 48, and the other end is connected to the bevel gear fixed at one end of the unit transverse shaft 47 by a fixed bevel gear. The other end of the unit transverse shaft 47 is vertically fixed on the pendulum body 43, one end of the sub-frame 46 is fixed on the branch frame 38, and the unit vertical shaft 44 and the unit transverse shaft 47 are respectively movably sleeved in two through holes opened on the sub-frame 46, the mainspring 45 is fixedly sleeved on the unit vertical shaft 44, and the outer end of the mainspring 45 is fixed on the sub-frame 46.

[0044] refer to Fig.14 It is understood that the air valve 42 includes an air disk 49, a plurality of evenly arranged limiting arc plates 51 vertically fixed to the edge of the air disk 49, and an L-shaped spring clip 50 for supporting the air disk 49. The air disk 49 covers the end of the air cylinder 41, and a return air hole is opened in the middle of the air disk 49. One end of the L-shaped spring clip 50 is fixed on the air cylinder 41.

[0045] In a row of switches 6, the switches 6 from one end to the other end move in turn to open the local airflow channel between the air inlet baffle plate 7 and the air outlet baffle plate 8, that is, the switch 6 moves and then resets, and then the adjacent switch 6 moves and resets, and the cycle continues. From the perspective of transmission: one end of the worm 19 is connected to the motor drive mechanism in the prior art, and the worm 19 continuously rotates to drive the double-acting shaft 17, thereby transmitting the split shafts 20 at both ends, and the split shafts 20 rotate to drive the closed-loop toothed belt 23 to move and transport, thereby driving the flat The plate portion 21 moves in a directional manner, and the flat plate portion 21 moves a row of brake units 12 one by one. When the flat plate portion 21 moves a single brake unit 12, one end of the movable plate 33 is supported by the T-shaped limit plate 27, and the other end of the movable plate 33 pushes the T-shaped push body 37 through the roller 32. In this way, the T-shaped push body 37 moves to drive the pressure gear 48 to rotate, and then drives the unit horizontal axis 47 through the unit vertical axis 44. Next, the swing body 43 swings to drive the unit rack 40, and the unit rack 40 moves to drive the exhaust plate 14. Fig.15 , the exhaust plate 14 descends and leaks out the strip holes on the exhaust baffle plate 8, and the strip holes on the air inlet baffle plate 7 are partially leaked due to the descending of the air inlet plate 16. In this way, the local airflow route controlled by the single switch 6 is unblocked, and the airflow naturally blows over the local heat dissipation surface of the battery 5. After the flat plate portion 21 completes the toggling of a single brake unit 12, it continues to toggle the next brake unit 12. The brake unit 12 that has been toggled is automatically reset. The power source for the reset is the spring 45 providing elastic force to reverse and reset the unit vertical shaft 44. Fig.12 , there is a mechanism here that the exhaust plate 14 rises and drives the L-shaped slow rod 36. The process of extracting the L-shaped slow rod 36 from the air cylinder 41 is restrained by the negative pressure in the air cylinder 41. The L-shaped slow rod 36 was inserted quickly before. Because the air in the air cylinder 41 impacts and lifts the air disk 49, the air disk 49 no longer blocks the end of the air cylinder 41, and the air in the air cylinder 41 can be quickly discharged. After the discharge, the air disk 49 resets and blocks it again. The air replenished in the air cylinder 41 can only be slowly carried out through the return air holes on the air disk 49. In this way, the L-shaped slow rod 36 extends slowly from the air cylinder 41, so the exhaust plate 14 resets slowly, and it takes some time for the switch 6 to re-block the local airflow channel between the air inlet baffle plate 7 and the exhaust baffle plate 8. During this period of time, there is sufficient heat dissipation and ventilation on the heat dissipation surface of the battery 5.

[0046] In addition, the present invention also has a mechanism for adjusting the ventilation and heat dissipation time according to the local temperature. If the temperature of the local heat dissipation surface of the battery 5 is too high, the temperature causes the deformation rod 30 to expand, and the deformation rod 30 extends to push the T-shaped limit plate 27. The T-shaped limit plate 27 further protrudes into the moving path of the flat plate portion 21. In this way, when the movable plate 33 is supported by the protruding T-shaped limit plate 27, the T-shaped push body 37 pushed by the other end of the movable plate 33 moves a greater distance. In this way, the exhaust plate 14 moves a greater distance through subsequent transmission, that is, the switch 6 moves a greater distance. In this way, more time is required for resetting the switch 6, so that it takes a longer time for the local airflow channel controlled by the switch 6 to be reclosed. This airflow channel is the area where the deformation rod 30 was previously extended. After sufficient ventilation and heat dissipation, the temperature of this local area drops, and the deformation rod 30 automatically shrinks and recovers its initial shape and length. In this way, from the overall functional analysis, a row of switches 6 open the corresponding local airflow channels in turn. When the local temperature is high, the closing time of this local channel will be delayed, thereby ensuring sufficient ventilation to cool this area.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
