DETAILED DESCRIPTION

[0019] 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 embodiments of 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. Example

[0020] like Figure 1-Figure 2 As shown, an embodiment of the present invention provides a flywheel energy storage control cabinet, including a cabinet assembly 1, a heat exchange assembly 2 and a fire extinguishing assembly 3.

[0021] In this embodiment, reference Figure 3 The cabinet assembly 1 includes a control cabinet 101, an electrical rail 102 arranged in the middle of the control cabinet 101, a flame monitoring sensor 104 arranged on one side of the control cabinet 101, and orifice plates arranged on both sides of the control cabinet 101 for control cables to pass through and be fixed. In this embodiment, the flame monitoring sensor 104 adopts existing mature technology and is commonly used in fire water cannons in Daxin Shopping Mall. Its technical principle will not be repeated here.

[0022] In this embodiment, reference Figure 4 The orifice plate includes a plurality of substrates 105 and clamping plates 106 which are cross-stacked with each other, wherein a plurality of holes 1 are opened on the substrate 105, and a plurality of holes 2 are opened on the clamping plate 106 at positions corresponding to the holes 1, and a plurality of convex teeth are arranged around the inner wall of the hole 2 toward the center point thereof. When the control cable is inserted into the hole 2, the control cable can be fixed in the hole 1 due to the deformation and extrusion of the convex teeth, thereby realizing orderly wiring arrangement.

[0023] In this embodiment, sound insulation cotton can be added to the inner wall of the control cabinet 101, and combined with the use of a perforated plate, the control cabinet 101 is in a better sealing state, thereby being able to effectively prevent dust and reduce noise.

[0024] In this embodiment, reference Figure 5-8 The heat exchange assembly 2 includes two flat tubes 201 arranged side by side on the rear side of the electrical rail 102, a sleeve 202 connected to the upper and lower ports of the flat tubes 201, a guide trough plate 209 arranged behind the flat tubes 201, and a fan 210 arranged at the top of the guide trough plate 209. The rear side of the flat tubes 201 is provided with heat dissipation fins 203, and the bottom of the guide trough plate 209 is installed with a deflection trough plate 211.

[0025] The heat exchange assembly 2 further includes a base 204 installed in the middle of the bottom wall of the control cabinet 101, inner tubes 1 205 provided on both sides of the base 204 and interconnected with each other, a top seat 206 installed in the middle of the top wall of the control cabinet 101, inner tubes 207 provided on both sides of the base 204 and independent of each other, and an air conditioner 208 whose inlet / outlet of the refrigeration medium is respectively connected to the top port of the inner tube 207. Among them, the inner tube 1 205 is respectively matched with the inside of the sleeve 202 at the bottom, and the inner tube 207 is respectively matched with the inside of the sleeve 202 at the top.

[0026] During the above operation, the refrigerant medium generated by the air conditioner 208 enters the inside of the flat tube 201 on one side through the inner tube 207 on one side, forms a loop reflux at the inner tube 1 205, and returns to the inside of the air conditioner 208 through the flat tube 201 on the other side and the inner tube 207. At the same time, the fan 210 forms convection with the hot air inside the control cabinet 101 through the internal groove of the guide groove plate 209, thereby completing heat exchange with the refrigerant medium through the heat dissipation fins 203, thereby achieving cooling of the control electrical components.

[0027] In this embodiment, the air conditioner 208 adopts the existing technology and is adaptively modified to adapt to the use of this solution, that is, the two inner tubes 207 are connected in series into the refrigerant medium circuit of the air conditioner 208. The modification technology is simple and the principle is feasible.

[0028] In this embodiment, reference Figure 9-13 The fire extinguishing assembly 3 includes a strip box 301 symmetrically arranged on both sides of the top wall of the control cabinet 101, and a bottom cover 304 hinged to the outer side of the bottom of the strip box 301, and the inner side of the bottom cover 304 is connected to the inner side of the bottom of the strip box 301 by magnetic attraction.

[0029] Among them, the strip box 301 has two inner and outer chambers. The inner chamber is provided with a fire blanket 302 stacked in an S shape. The top of the fire blanket 302 is connected to the top wall of the inner chamber, and the bottom is connected to a counterweight. The outer chamber is provided with air bags 303 stacked in an S shape. The air bags 303 are connected to high-pressure gas tanks 305 through control valves.

[0030] In this embodiment, once a flame is detected, the control valve is immediately opened briefly, so that a small amount of high-pressure inert gas in the high-pressure gas tank 305 is injected into the airbag 303, and then the inflated airbag 303 breaks open the bottom cover 304, and then the fire blanket 302 falls freely under the action of the counterweight block and quickly unfolds on both sides of the control electrical component. Then the control valve is continuously opened, so that the high-pressure inert gas in the high-pressure gas tank 305 is completely injected into the airbag 303, and then the inflated airbag 303 quickly squeezes the fire blanket 302 completely to cover the control electrical component, thereby achieving barrier fire extinguishing.

[0031] The fire blanket 302 is stacked in an S-shape to facilitate free fall and deployment during fire extinguishing. The airbag 303 is stacked in an S-shape to facilitate rapid expansion and deployment.

[0032] The fire extinguishing assembly 3 also includes a cover 307 installed on the top of the control cabinet 101, and a conduit 306 connecting the cover 307 and the inside of the control cabinet 101. A one-way valve is provided inside the conduit 306 so that only the gas inside the control cabinet 101 can flow to the inside of the cover 307. A column cavity 308 is provided at the rear of the cover 307. The top port of the column cavity 308 is connected to the inside of the cover 307. A sealing cover 309 is magnetically attracted to the bottom port. A telescopic folding tube 310 is connected to the top of the sealing cover 309. The top port of the telescopic folding tube 310 is connected to the top port of the column cavity 308.

[0033] As mentioned above, a large amount of harmful smoke will be generated in the event of a fire. Therefore, when the airbag 303 expands rapidly, the one-way valve is designed to open due to the impact of the high-pressure gas inside the control cabinet 101. As a result, the high-pressure gas containing a large amount of harmful combustion substances inside the control cabinet 101 is squeezed into the cover 307 by the airbag 303, and then enters the telescopic folding tube 310 through the column cavity 308. After the telescopic folding tube 310 passively expands its volume, it is temporarily stored inside it, thereby avoiding the leakage of harmful combustion substances such as thick smoke.

[0034] Wire forks 103 are provided on both sides of the control cabinet 101 . The wire forks 103 are located between the endpoints of two strip boxes 301 . The strip boxes 301 are all arc-shaped. The endpoint chords of the two strip boxes 301 are parallel to each other and are located between the two strip boxes 301 .

[0035] In this embodiment, in order to enable the fire blanket 302 to be better unfolded from both sides to cover the control electrical components, the strip box 301 is set to be arc-shaped, and the control cables are arranged with a cable fork 103 and placed between the ends of the two fire blankets 302.

[0036] This embodiment also provides a method for using a flywheel energy storage control cabinet, comprising the following steps: Step 1: The control electrical components are installed on the electrical rail 102 , and the control cables connected thereto are bent and neatly arranged in the cable fork 103 , and then sequentially pass through the cable fork 103 , the substrate 105 , and the clamping plate 106 to be connected to the external control circuit.

[0037] Step 2, when working, the refrigerant medium generated by the air conditioner 208 enters the inside of the flat tube 201 on one side through the inner tube 207 on one side, and forms a loop reflux at the inner tube 1 205, and returns to the inside of the air conditioner 208 through the flat tube 201 on the other side and the inner tube 207. At the same time, the fan 210 forms convection with the hot air inside the control cabinet 101 through the internal groove of the guide groove plate 209, thereby completing heat exchange with the refrigerant through the heat dissipation fins 203, thereby achieving cooling of the control electrical components.

[0038] Step three, once the flame monitoring sensor 104 detects the generation of flame, it will immediately feedback, and then the control valve will be briefly opened, so that a small amount of high-pressure inert gas in the high-pressure gas tank 305 is injected into the airbag 303, and then the inflated airbag 303 breaks open the bottom cover 304, and then the fire blanket 302 falls freely under the action of the counterweight block, and quickly unfolds on both sides of the control electrical component, and then the control valve is continuously opened, so that the high-pressure inert gas in the high-pressure gas tank 305 is completely injected into the airbag 303, and then the inflated airbag 303 quickly squeezes the fire blanket 302 completely to cover the control electrical component, thereby achieving barrier fire extinguishing.

[0039] Step 4. When the airbag 303 expands rapidly, the one-way valve is opened by the impact of the high-pressure gas inside the control cabinet 101, so that the high-pressure gas containing a large amount of harmful combustion substances inside the control cabinet 101 is filled into the cover 307 under the squeeze of the airbag 303, and then enters the telescopic folding tube 310 through the column cavity 308. After the telescopic folding tube 310 passively expands its volume, it is temporarily stored inside it, thereby avoiding the leakage of harmful combustion substances such as thick smoke.

[0040] 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.
