Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic inverters, and in particular to a photovoltaic inverter with a protection device. Background Art

[0002] An inverter is a converter that converts DC power (battery, storage bottle) into constant frequency and voltage or frequency and voltage regulated AC power. It consists of an inverter bridge, control logic and filter circuit. However, in real life, we find that when the inverter is working, it will generate a lot of heat. When the circuit fails, overloads, the temperature is too high, the heat dissipation is poor or some other environmental factors occur, the inverter will spontaneously combust. However, under the sun, these solar panels can generate more than one thousand volts of DC high voltage, and it is impossible to put out the fire manually. The only way is to wait until the sun sets or the solar panels burn out. However, this will cause the fire to be out of control and cause great losses. For this reason, we propose a photovoltaic inverter with a protective device. Summary of the invention

DETAILED DESCRIPTION

[0035] 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

[0036] See also Figure 1-12 The present invention provides a technical solution: a photovoltaic inverter with a protective device, comprising a bracket body 1, an inverter body 2 and a plug 3 arranged below the inverter body 2, and also comprising

[0037] The connecting pipe 4 is arranged in the inverter body 2 and is used to assist in extinguishing the fire after the inverter body 2 catches fire;

[0038] The water cooling element 5 is arranged in the inverter body 2 and is used to store water and assist the inverter body 2 in heat dissipation;

[0039] The automatic fire extinguishing assembly 6 is arranged in the inverter body 2 and is used to control the inverter body 2 to separate from the support body 1 and automatically extinguish the fire when the inverter body 2 spontaneously ignites.

[0040] The water cooling component 5 includes a micro water pump 51 arranged in the inverter body 2, a flow pipe 52 is arranged at the output end of the micro water pump 51, and the flow pipe 52 is arranged throughout the inverter body 2, the output end of the micro water pump 51 is connected to one end of the connecting pipe 4, and the end of the flow pipe 52 away from the micro water pump 51 and the end of the connecting pipe 4 away from the micro water pump 51 are at the same axis, the micro water pump 51 in the inverter body 2 will make the water flow in the flow pipe 52 continue to be in motion, and then the water flow will bring the heat in the inverter body 2 out of the inverter body 2 through the water flow, which can reduce the temperature accumulation in the inverter body 2, thereby reducing the spontaneous combustion phenomenon caused by the high temperature in the inverter body 2.

[0041] The automatic fire extinguishing assembly 6 includes a driving member 7 arranged in the inverter body 2, which is used to provide power for the automatic fire extinguishing of the inverter body 2; a disconnecting member 8 is arranged in the inverter body 2, which is used to control the plug 3 to be separated from the inverter body 2; two transmission members 9 are arranged in the inverter body 2, which are used to transmit power for the inverter body 2 to be separated from the bracket body 1; a synchronization member 10 is arranged in the inverter body 2, which is used to synchronously control the inverter body 2 to be separated from the bracket body 1 and to discharge the water in the circulation pipe 52; a separation member 11 is arranged above the inverter body 2, which is used to control the inverter body 2 to be separated from the bracket body 1; a drainage member 12 is arranged on the outside of the connecting pipe 4, which is used to control the water in the circulation pipe 52 to be sprayed out after the inverter body 2 catches fire.

[0042] The driving member 7 includes two driving plates 71 arranged in the inverter body 2, and a driving box 72 is arranged at the opposite ends of the two driving plates 71. A pressing plate 73 is slidably arranged in the driving box 72, and a plurality of pressing rods 74 are arranged at the bottom of the pressing plate 73. The plurality of pressing rods 74 are all slidably arranged in the driving box 72, and a liquid that expands when heated is stored above the pressing plate 73 in the driving box 72. When a fire occurs in the inverter body 2, the temperature in the inverter body 2 rises, and the high temperature in the inverter body 2 causes the driving member 7 to The heat-expanding liquid in the box 72 begins to expand. The heat-expanding liquid is mercury. When the mercury expands, the expanded mercury will push the extrusion plate 73 in the drive box 72, causing the extrusion plate 73 to slide in the drive box 72. When the extrusion plate 73 moves downward, the extrusion plate 73 will push the multiple extrusion rods 74 at its bottom, causing the multiple extrusion rods 74 to push it away from the off-line plate 82 at one end of the extrusion plate 73. Its function is to use the property of mercury's expansion when it is exposed to heat to make it a safe fire extinguishing drive without the need for manual intervention in extinguishing the fire.

[0043] The off-line member 8 includes a fixed block 81 arranged on both sides of the plug 3, a plurality of off-line plates 82 are arranged at the bottom of the multiple extrusion rods 74, a plurality of arc plates 83 are arranged at the bottom of the off-line plate 82, the plurality of arc plates 83 are all slidably arranged in the inverter body 2, and the plurality of arc plates 83 are used in conjunction with the adjacent fixed blocks 81, and an off-line spring 84 is arranged at the bottom of the off-line plate 82. When the off-line plate 82 is pushed by the extrusion rod 74, the off-line plate 82 will push the plurality of arc plates 83 at its bottom downward, thereby causing the plurality of arc plates 83 to move downward. When the plurality of arc plates 83 move downward, the plurality of arc plates 83 move downward. The arc-shaped plate 83 will push the fixed blocks 81 below it on both sides of the plug 3, so that the multiple arc-shaped plates 83 can separate the plug 3 from the inverter body 2 through the fixed blocks 81. The off-line spring 84 arranged at the bottom of the off-line plate 82 can prevent the plug 3 from being separated from the inverter body 2 due to excessive weight above the off-line plate 82 when the inverter body 2 is in normal use. Its function is to preferentially disconnect the line connected to the inverter body 2 when the inverter body 2 catches fire, so as to avoid causing more losses while not affecting the discharge of water in the flow pipe 52.

[0044] The transmission member 9 includes a first support frame 91 arranged in the inverter body 2, a shaft 92 is rotatably arranged on the first support frame 91, a winding wheel 93 is arranged on the outer side of the shaft 92, a ratchet 94 is arranged on the outer side of the shaft 92, a transmission rope 95 is wound around the outer side of the winding wheel 93, an insertion rod 96 is arranged at one end of the transmission rope 95 away from the winding wheel 93, a torsion spring 97 is arranged at one end of the shaft 92, and the end of the torsion spring 97 away from the shaft 92 is arranged on the first support frame 91, an auxiliary block 98 is arranged in the inverter body 2, and the insertion rod 96 is slidably arranged in the auxiliary block 98, A second support frame 99 is provided in the inverter body 2, and a second shaft 910 is rotatably provided on the second support frame 99, and a second torsion spring 911 is provided at one end of the second shaft 910, and the end of the second torsion spring 911 away from the second shaft 910 is provided on the second support frame 99, and a ratchet 912 used in conjunction with the ratchet 94 is provided on the second shaft 910, and the end of the ratchet 912 away from the ratchet 94 is located below the off-line plate 82. When the plug 3 is separated from the inverter body 2 and the off-line plate 82 reaches the bottom of the inner wall of the inverter body 2, the off-line plate 82 will perform a rotation on one end of the ratchet 912 at both ends. When the end of the ratchet 912 away from the ratchet wheel 94 is squeezed by the off-line plate 82, the ratchet 912 is tilted up at the end close to the ratchet wheel 94 under the action of the second shaft 910. The torsion spring 2 911 arranged at one end of the second shaft 910 can prevent the ratchet 912 from being out of control of the ratchet wheel 94 when the inverter body 2 is in normal use, thereby affecting the normal operation of the inverter body 2. When the ratchet 912 is tilted up at the end close to the ratchet wheel 94, the ratchet wheel 94 will rotate under the action of the torsion spring 1 97. When the torsion spring 1 97 controls the ratchet wheel 94 to rotate through the shaft 1 92, the torsion spring 1 911 arranged at one end of the second shaft 910 can prevent the ratchet 912 from being out of control of the ratchet wheel 94 when the inverter body 2 is in normal use, thereby affecting the normal operation of the inverter body 2. The winding wheel 93 on the outside of the shaft 1 92 will rotate along with the shaft 1 92. At this time, the transmission rope 95 wound around the outside of the winding wheel 93 begins to wind up, so that the insertion rod 96 at one end of the transmission rope 95 is pulled, so that the insertion rod 96 slides in the slot 102 provided on the auxiliary block 98 and the synchronization frame 101, and is separated from the control of the synchronization frame 101. Its function is to control the inverter body 2 to separate from the bracket body 1 after the plug 3 is separated, so as to avoid the inverter body 2 being separated first and then pulling the plug 3 when the inverter body 2 falls freely, resulting in greater losses.

[0045] The synchronous member 10 includes a synchronous frame 101 arranged in the inverter body 2, and a card slot 102 for use with the insertion rod 96 is opened at the bottom of the synchronous frame 101, and the insertion rod 96 is slidably arranged in the card slot 102, and a lifting rod 103 is arranged on the side of the synchronous frame 101 close to the flow pipe 52, and a pull rod 104 is arranged on the top of the synchronous frame 101. When the synchronous frame 101 moves upward under the action of the pull rod 104, the lifting rod 103 on one side of the synchronous frame 101 will move upward with the synchronous frame 101, so that the rising lifting rod 103 lifts the lever 125, which has the function of synchronously controlling the inverter body 2 to separate from the bracket body 1, and controlling the water flow in the flow pipe 52 and the connecting pipe 4 to disperse in the inverter body 2, so as to extinguish the inverter body 2.

When the synchronous frame 101 is separated from the control of the insertion rod 96, the pull rod 104 arranged on the top of the synchronous frame 101 will be released under the action of the disengagement spring 115. When the pull rod 104 moves upward, the disengagement plate 114 arranged on the top thereof will move upward together under the action of the disengagement spring 115. When the disengagement plate 114 moves upward, the two locking rods 116 slidingly arranged in the installation box 113 will move toward each other along the inclined surfaces at both ends of the disengagement plate 114 under the action of the locking springs 117 on the outside thereof, until the two locking rods 116 are disengaged from the locking grooves 118 on the two limit rods 111. When the two locking rods 116 are disengaged from the two locking grooves 118, the inverter body 2 will slide on the outside of the corresponding limit rods 111 through the two limit grooves 112, and then the inverter body 2 will be disengaged from the limit rod 111, so that the inverter body 2 is disengaged from the bracket body 1. Its function is to be able to disengage from the bracket body 1 in time after the inverter body 2 spontaneously ignites, so that the burning inverter body 2 is away from the photovoltaic panel.

[0047] The drainage member 12 includes two bearings 121 arranged on the outside of the connecting pipe 4, sleeves 122 are arranged on the opposite sides of the two bearings 121, and the sleeves 122 are rotatably arranged on the outside of the connecting pipe 4, a plurality of water spraying grooves 1 123 are opened on the outside of the connecting pipe 4, and a water spraying groove 2 124 used in conjunction with the plurality of water spraying grooves 1 123 is opened on the outside of the sleeve 122. In an initial state, the plurality of water spraying grooves 1 123 and the plurality of water spraying grooves 2 124 do not overlap, a lever 125 is arranged on the outside of the sleeve 122, and the lever 125 is located above the lifting rod 103, a plurality of connecting plates 126 are arranged on the outside of the sleeve 122, and a rotating ring 127 is arranged on one end of the plurality of connecting plates 126 away from the sleeve 122, and the rotating ring 127 is rotatably arranged on the outside of the connecting pipe 4, A plurality of round rods 128 are arranged on one side of the rotating ring 127 away from the plurality of connecting plates 126, a one-way valve 129 is arranged in the connecting pipe 4, a fixed ring 1210 is arranged at one end of the circulation pipe 52 close to the connecting pipe 4, a thread groove 1211 is arranged on the outer side of the fixed ring 1210, a movable ring 1212 is arranged on the outer side of the fixed ring 1210, and the movable ring 1212 is threadedly connected with the fixed ring 1210 through the thread groove 1211, a through hole 1213 for use with the plurality of round rods 128 is opened on the outer side of the movable ring 1212, and the plurality of round rods 128 are slidably and rotatably arranged in the movable ring 1212 through the plurality of through holes 1213, a connecting pipe 1214 for use with the one-way valve 129 is arranged in the movable ring 1212, and the connecting pipe 1214 is arranged in the movable ring 1212, and the connecting pipe 1214 is arranged in the movable ring 1212. The tube 1214 is slidably arranged in the circulation tube 52. When the lever 125 is lifted by the lifting rod 103, the lever 125 will drive the sleeve 122 on one side thereof to rotate through the bearings 121 at both ends thereof. After the sleeve 122 rotates, the second water spraying groove 124 on the outside of the sleeve 122 will communicate with the first water spraying groove 123 on the outside of the connecting tube 4, so that the water flow in the circulation tube 52 and the connecting tube 4 will be sprayed out through the first water spraying groove 123 and the second water spraying groove 124 under the action of the micro water pump 51. When the sleeve 122 rotates, the connecting plate 126 arranged on the outside of the sleeve 122 will drive the rotating ring 127 at one end thereof to rotate, so that the rotating ring 127 drives the multiple round rods 128 on one side thereof to rotate. When the multiple round rods 128 are under the action of the rotating ring 127, the rotating ring 127 can rotate the multiple round rods 128 on one side thereof. When the movable ring 1212 rotates downward, the multiple round rods 128 will pass through the multiple through holes 1213 corresponding thereto to control the rotation of the movable ring 1212. When the movable ring 1212 rotates, the movable ring 1212 will move toward the end away from the connecting pipe 4 through the thread groove 1211 on the fixed ring 1210, so that the movable ring 1212 drives the connecting pipe 1214 at one end thereof to disengage from the one-way valve 129, so that the one-way valve 129 blocks the end of the connecting pipe 4 close to the flow pipe 52, so that the water flow in the connecting pipe 4 can only be sprayed out through the water spraying groove 123 and the water spraying groove 2 124. After the connecting pipe 1214 is separated from the one-way valve 129, air will begin to enter the flow pipe 52. At this time, the micro water pump 51 will discharge all the water flow in the flow pipe 52 to the connecting pipe 4.All water in the connecting pipe 4 and the flow pipe 52 is sprayed out through the water spray trough 1 123 and the water spray trough 2 124. Its function is to separate the connecting pipe 4 from the flow pipe 52 and discharge all water to the connecting pipe 4 and discharge it through the small holes of the water spray trough 1 123 and the water spray trough 2 124, so as to achieve the function of automatic fire extinguishing.

[0048] When in use, the micro water pump 51 in the inverter body 2 will keep the water flow in the circulation pipe 52 in a state of continuous motion, so that the water flow will bring the heat in the inverter body 2 out of the inverter body 2 through the water flow. When a fire occurs in the inverter body 2, the temperature in the inverter body 2 rises. The high temperature in the inverter body 2 will cause the heat-expanding liquid in the drive box 72 to begin to expand. The heat-expanding liquid is mercury. When the mercury expands, the expanded mercury will push the extrusion plate 73 in the drive box 72, causing the extrusion plate 73 to slide in the drive box 72. When the extrusion plate 73 moves downward, the extrusion plate 73 will push the multiple extrusion rods 74 at its bottom, causing the multiple extrusion rods 74 to push the off-line plate 82 away from one end of the extrusion plate 73. When the off-line plate 82 is squeezed by the extrusion rods 74, the extrusion plate 73 will be pushed away from the off-line plate 82. When pushed, the off-line plate 82 will push the multiple curved plates 83 at its bottom downward, so that the multiple curved plates 83 move downward. When the multiple curved plates 83 move downward, the multiple curved plates 83 will push the fixing blocks 81 below them on both sides of the plug 3, so that the multiple curved plates 83 can separate the plug 3 from the inverter body 2 through the fixing blocks 81. The off-line spring 84 arranged at the bottom of the off-line plate 82 can prevent the plug 3 from being separated from the inverter body 2 due to excessive weight above the off-line plate 82 when the inverter body 2 is in normal use. When the plug 3 is separated from the inverter body 2 and the off-line plate 82 reaches the bottom of the inner wall of the inverter body 2, the off-line plate 82 will squeeze one end of the ratchet teeth 912 at both ends of it. When the ratchet teeth 912 are away from one end of the ratchet wheel 94 After being squeezed by the off-line plate 82, the ratchet 912 is tilted up near one end of the ratchet 94 under the action of the second shaft 910. The torsion spring 2 911 arranged at one end of the second shaft 910 can prevent the ratchet 912 from being out of control of the ratchet 94 when the inverter body 2 is in normal use, thereby affecting the normal operation of the inverter body 2. When the ratchet 912 is tilted up near one end of the ratchet 94, the ratchet 94 will rotate under the action of the torsion spring 1 97. When the torsion spring 1 97 controls the rotation of the ratchet 94 through the shaft 1 92, the winding wheel 93 arranged on the outside of the shaft 1 92 will rotate with the shaft 1 92. At this time, the transmission rope 95 wound around the outside of the winding wheel 93 begins to reel, so that the insertion rod 96 at one end of the transmission rope 95 is pulled, causing the insertion rod 96 to slide The synchronous frame 101 is in the slot 102 opened on the auxiliary block 98 and the synchronous frame 101, and the control of the synchronous frame 101 is broken away. When the synchronous frame 101 is broken away from the control of the plug rod 96, the pull rod 104 arranged on the top of the synchronous frame 101 will move upward under the action of the breakaway spring 115. When the pull rod 104 moves upward, the breakaway plate 114 arranged on the top thereof will move upward together under the action of the breakaway spring 115. When the breakaway plate 114 moves upward, the two locking rods 116 slidingly arranged in the installation box 113 will move toward each other along the inclined surfaces at both ends of the breakaway plate 114 under the action of the locking springs 117 on the outside thereof, until the two locking rods 116 break away from the locking slots 118 on the two limit rods 111. When the two locking rods 116 break away from the two locking slots 118,The inverter body 2 will slide on the outside of the corresponding limiting rod 111 through the two limiting grooves 112, and then the inverter body 2 will break away from the limiting rod 111, so that the inverter body 2 will break away from the bracket body 1. When the synchronous frame 101 moves upward under the action of the pull rod 104, the lifting rod 103 on one side of the synchronous frame 101 will move upward with the synchronous frame 101, so that the rising lifting rod 103 will lift the lever 125. When the lever 125 is lifted by the lifting rod 103, the lever 125 will drive one side of the lifting rod 103 to move upward. The sleeve 122 on the side rotates through the bearings 121 at both ends thereof. When the sleeve 122 rotates, the second water spraying groove 124 on the outside of the sleeve 122 will communicate with the first water spraying groove 123 on the outside of the connecting pipe 4, so that the water flow in the flow pipe 52 and the connecting pipe 4 will be sprayed out through the first water spraying groove 123 and the second water spraying groove 124 under the action of the micro water pump 51. When the sleeve 122 rotates, the connecting plate 126 arranged on the outside of the sleeve 122 will drive the rotating ring 127 at one end thereof to rotate, so that the rotating ring 127 27 drives the multiple round rods 128 on one side to rotate. When the multiple round rods 128 rotate under the action of the rotating ring 127, the multiple round rods 128 will pass through the multiple through holes 1213 corresponding to them to control the rotation of the moving ring 1212. When the moving ring 1212 rotates, the moving ring 1212 will move to the end away from the connecting pipe 4 through the thread groove 1211 on the fixed ring 1210, so that the moving ring 1212 drives the connecting pipe 1214 at one end thereof to separate from the one-way valve 129, so that the one-way The valve 129 blocks the end of the connecting pipe 4 close to the flow pipe 52, so that the water in the connecting pipe 4 can only be sprayed out through the water spray trough 123 and the water spray trough 2 124. After the connecting pipe 1214 is separated from the one-way valve 129, air will begin to enter the flow pipe 52. At this time, the micro water pump 51 will discharge all the water in the flow pipe 52 to the connecting pipe 4, so that all the water in the connecting pipe 4 and the flow pipe 52 will be sprayed out through the water spray trough 123 and the water spray trough 2 124, achieving the effect of automatic fire extinguishing. Example

[0049] See also Figure 13-15 , the present invention provides a technical solution:

[0050] Different from the embodiment 1, the bracket body 1 is provided with an exhaust member 13 for assisting the water flow in the circulation pipe 52 to dissipate heat. The exhaust member 13 includes a suspension rod 131 provided on the bracket body 1, an exhaust cover 132 is provided at the bottom of the suspension rod 131, and a plurality of exhaust slots 133 are provided on one side of the exhaust cover 132. A rotating shaft 134 is rotatably provided in the exhaust cover 132, and a plurality of exhaust plates 135 are provided outside the rotating shaft 134, and the plurality of exhaust plates 135 are all arc-shaped, and a bottom plate 136 is provided at the bottom of the exhaust plate 135. A rotating shaft 134 is provided inside the exhaust cover 132. A rotating rod 137 is provided, and a plurality of wind-picking rods 138 are provided on the top of the rotating rod 137. A hemispherical body 139 is provided at one end of the plurality of wind-picking rods 138 away from the rotating rod 137. A first gear 1310 is provided on the outer side of the rotating rod 137. A second gear 1311 meshing with the first gear 1310 is provided on the outer side of the rotating shaft 134, and the radius of the first gear 1310 is greater than that of the second gear 1311. When the plurality of hemispherical bodies 139 are blown by wind, the plurality of hemispherical bodies 139 will drive the rotating rod 137 to rotate through the wind-picking rod 138. When the rotating rod 137 is blown by wind, the plurality of hemispherical bodies 139 will drive the rotating rod 137 to rotate. When the first gear 1310 rotates, the second gear 1311 meshed with the first gear 1310 will rotate synchronously in the opposite direction under the action of the first gear 1310. Since the radius of the first gear 1310 is larger than that of the second gear 1311, the rotation speed of the rotating shaft 134 at the axis of the second gear 1311 will be faster than that of the rotating rod 137 at the axis of the first gear 1310. When the second gear 1311 drives the rotating shaft 134 to rotate, The multiple exhaust plates 135 arranged on the outside of the rotating shaft 134 will rotate with the rotating shaft 134, thereby forming wind flow. The formed wind flow will be discharged through the multiple exhaust slots 133 opened on the outside of the exhaust cover 132, and blown to the flow pipe 52 exposed on the outside of the inverter body 2, so that the water flow temperature in the flow pipe 52 is reduced faster. Its function is to use natural wind as a drive and amplify the rotation speed through the first gear 1310 and the second gear 1311, so that the wind flow generated by the exhaust plate 135 is greater than the natural wind, thereby cooling the water in the flow pipe 52.
