Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic prefabricated cabins, and in particular to a photovoltaic prefabricated cabin. Background Art

[0002] A photovoltaic prefabricated cabin is a prefabricated substation designed specifically for photovoltaic power generation. Through modularization and prefabrication, the key equipment in the photovoltaic power generation system (such as inverters, transformers, switch cabinets, etc.) are integrated into a prefabricated cabin. The photovoltaic prefabricated cabin is usually set up outdoors in a sunny place.

[0003] In the related art, a photovoltaic prefabricated cabin includes a box body and a door. The door is rotatably connected to the box body, and heat dissipation holes are opened on the box body.

[0004] The internal circuit of the box may cause flames on the line due to aging or short circuit. Since the box is set outdoors, it is difficult for staff to deal with it in time, making it difficult to extinguish the fire in time, which may cause a fire inside the box. Summary of the invention

[0005] In order to improve the problem of fire easily occurring inside the box, the present application provides a photovoltaic prefabricated cabin.

[0006] The present application provides a photovoltaic prefabricated cabin, which adopts the following technical solution:

[0007] A photovoltaic prefabricated cabin comprises a box body and a box door, wherein the box door is rotatably connected to the box body, the box body is provided with heat dissipation holes, the box body is provided with a temperature sensor, the temperature sensor is provided with a driving member, and the driving member is provided with a baffle for blocking the heat dissipation holes; when a fire occurs in the box body, the temperature sensor drives the baffle to block the heat dissipation holes through the driving member.

[0008] By adopting the above technical solution, when a fire occurs inside the box, the temperature sensor can detect abnormal temperature, and the temperature sensor transmits a signal to the driver, which drives the baffle to move so that the baffle can block the heat dissipation holes. At this time, the channel for air exchange between the box and the outside air is blocked, making the oxygen in the box insufficient to support large-scale combustion, so that the fire in the box is gradually extinguished due to lack of oxygen.

[0009] Optionally, a receiving groove is provided on the box body, a fire extinguishing bag is provided in the receiving groove, and a puncture strip is provided on the baffle plate, and the puncture strip is located in the receiving groove; when the baffle plate blocks the heat dissipation hole, the puncture strip cuts the fire extinguishing bag, and the fire extinguishing bag can extinguish the flame.

[0010] By adopting the above technical solution, when the baffle blocks the heat dissipation, the puncture strip slides in the receiving groove, allowing the puncture strip to cut the fire extinguishing bag, so that the fire extinguishing bag is opened, allowing the fire extinguishing bag to extinguish the flame in the box, reduce the further spread of the fire, and further reduce the damage inside the prefabricated cabin.

[0011] Optionally, an accommodating spring is provided in the accommodating groove, and an accommodating plate is provided on the accommodating spring, and the accommodating spring drives the accommodating plate to protrude from the accommodating groove; when the baffle blocks the accommodating groove, the baffle does not block the heat dissipation hole; when the baffle blocks the heat dissipation hole, the baffle does not block the accommodating groove.

[0012] By adopting the above technical solution, the accommodating spring drives the accommodating plate to protrude from the accommodating groove, and the accommodating plate drives the fire extinguishing bag to protrude from the accommodating groove, and the fire extinguishing bag is moved into the box body, so that the fire extinguishing bag can be spread over a large area in the box body, so that the fire extinguishing bag can extinguish the flame, further shortening the time of fire.

[0013] Optionally, the baffle is provided with a stop hole for the fire extinguishing bag to pass through, a stop plate is rotatably connected to the stop hole, a stop strip is slidably connected to the stop plate, and a stop groove is provided on the stop plate for the stop strip to be inserted into; when the stop strip is inserted into the stop groove, the stop plate blocks the stop hole.

[0014] By adopting the above technical solution, the stop strip is inserted into the stop groove, so that the stop plate can be fixed in the stop hole, and the stop plate can block the stop hole, thereby limiting the fire extinguishing bag from detaching from the stop hole; after the fire extinguishing bag is used, the staff slides the stop strip to disengage the stop strip from the stop groove, so that the stop plate can be opened. At this time, the fire extinguishing bag can pass through the stop hole and be installed in the receiving groove, so that the fire extinguishing bag will not be scratched by the puncture strip during installation.

[0015] Optionally, a through hole is provided on the box door, and a movable component for inserting into the through hole is slidably connected to the box body, and the movable component is located on the moving path of the baffle; when the baffle blocks the heat dissipation hole, the movable component is inserted into the through hole, and the box door is difficult to rotate.

[0016] By adopting the above technical solution, when the baffle blocks the heat dissipation holes, since the moving component is located on the moving path of the baffle, the baffle pushes the moving component to slide on the box body, so that the moving component can be inserted into the through-hole, thereby realizing the limiting of the box door by the moving component, making it difficult for the box door to rotate on the box body, thereby avoiding the staff from accidentally opening the box door and reducing the problem of the staff opening the box door and causing external air to enter the box body and cause the flame to reignite. When the temperature inside the box becomes normal, the baffle does not block the heat dissipation holes. At this time, the staff drives the moving component to move to allow the moving component to disengage from the through-hole to facilitate the opening of the box door.

[0017] Optionally, a fixing strip is slidably connected in the through hole; when the movable component is inserted into the through hole, the fixing strip protrudes from the box door.

[0018] By adopting the above technical solution, when the movable component is inserted into the through-hole, the movable component drives the fixed bar to protrude from the box door. At this time, the staff can directly observe the protrusion of the fixed bar, so that the staff can know that there is a fire inside the box; when the flame inside the box is extinguished and the temperature returns to normal, the staff moves the movable component through the fixed bar to disengage the movable component from the through-hole to open the box door.

[0019] Optionally, the moving component includes a moving bar, a moving spring and a moving block, the moving bar is slidably connected to the box body, the moving spring is arranged between the moving bar and the moving block, and the moving block can be inserted into the through hole; when the fixed bar is inserted into the through hole, the moving block is detached from the through hole.

[0020] By adopting the above technical solution, the moving spring is located between the moving bar and the moving block. When the staff forcibly presses the fixed bar, the fixed bar can drive the moving block to move, causing the moving spring to be compressed, so that the moving block can be separated from the perforation, so that the staff can control the fire without waiting for the air inside the box to be consumed. The fire can be controlled when the staff arrives in time, further accelerating the efficiency of extinguishing the fire.

[0021] Optionally, a limit bar is provided on the moving block, and a limit groove is opened on the moving bar for inserting the limit bar. Rotating blocks are fixedly connected to both ends of the moving spring, and the two rotating blocks are respectively rotatably connected to the moving bar and the moving block; when the limit bar is inserted into the limit groove, the moving block can be detached from the through hole; when the limit bar abuts against the end face of the moving bar, the moving block is located in the through hole.

[0022] By adopting the above technical solution, the staff rotates the fixed bar to allow the fixed bar to drive the moving block to rotate. Since both ends of the moving spring are fixedly connected to the rotating block, and the two rotating blocks are respectively rotatably connected to the moving bar and the moving block, the moving block can rotate on the moving bar, so that the limit bar can be inserted into the limit groove, so that the moving block can move in the direction of the moving bar, and the moving block can be separated from the through-hole; when the limit bar abuts against the end face of the moving bar, the moving block cannot move in the direction of the moving bar, so that the moving block can be located in the through-hole, avoiding the moving block from being separated from the through-hole, and further allowing the cabinet door to be relatively stable when the moving block is located in the through-hole.

[0023] Optionally, a fixing block is provided on the fixing bar, and a fixing groove for inserting the fixing block is provided on the moving block; when the fixing block is inserted into the fixing groove, the fixing bar and the moving block are fixed to each other.

[0024] By adopting the above technical solution, the fixed block is inserted into the fixed groove, and the fixed block drives the groove wall of the fixed groove, so that the fixed block can move the moving block more stably, the limit bar is inserted into the limit groove, and the moving block moves toward the moving bar.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. When a fire occurs inside the box, the temperature sensor can detect that the temperature is too high. The temperature sensor transmits a signal to the driver, which drives the baffle to move so that the baffle can block the heat dissipation holes. At this time, the channel for air exchange between the box and the outside air is blocked, making the oxygen in the box insufficient to support large-scale combustion, so that the fire in the box is gradually extinguished due to lack of oxygen.

[0027] 2. When the baffle blocks the heat dissipation holes, since the moving component is located on the moving path of the baffle, the baffle pushes the moving component to slide on the box body, so that the moving component can be inserted into the perforation, thereby limiting the box door by the moving component, making it difficult for the box door to rotate on the box body, thereby preventing the staff from accidentally opening the box door and reducing the problem of the staff opening the box door and causing external air to enter the box and cause the flame to reignite. When the temperature inside the box becomes normal, the baffle does not block the heat dissipation holes. At this time, the staff drives the moving component to move and let the moving component disengage from the perforation to facilitate the opening of the box door. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is combined with Figure 1-6 This application is described in further detail.

[0036] This embodiment discloses a photovoltaic prefabricated cabin. Figure 1 A photovoltaic prefabricated cabin includes a box body 1 and a plurality of box doors 2, wherein the plurality of box doors 2 are rotatably connected to the box body 1. A plurality of heat dissipation holes 11 are fixedly connected to the top of the box body 1, and the heat dissipation holes 11 are used for air exchange between the inside and outside of the box body 1.

[0037] Reference Figure 2 The box body 1 is provided with a plurality of placement slots 12 for placing the electrical components. A plurality of fireproof panels 121 are fixedly connected to the slot walls of the placement slots 12. The plurality of fireproof panels 121 are arranged in an array along the length direction of the box body 1, and the placement slots 12 between two adjacent fireproof panels 121 are not connected to each other.

[0038] Reference Figure 2 A plurality of temperature sensors 13 are provided on the placement groove 12, and a driving member 14 is electrically connected to the temperature sensor 13. The driving member 14 includes a driving cylinder, and the driving cylinder is fixedly connected to the groove wall of the placement groove 12. A baffle 141 is fixedly connected to the driving shaft of the driving cylinder, and the baffle 141 is used to block the plurality of heat dissipation holes 11.

[0039] Reference Figure 2 When a fire occurs in the placement groove 12, the temperature in the placement groove 12 rises, and the temperature sensor 13 detects the abnormal temperature. The temperature sensor 13 is activated by the driving cylinder. At this time, the driving cylinder drives the baffle 141 to completely block the opening of the heat dissipation hole 11, so that the placement groove 12 is sealed, so that the oxygen in the placement groove 12 is consumed by the fire to avoid a larger fire.

[0040] Reference Figure 3A receiving groove 15 is provided on the groove wall of the placement groove 12 away from the ground, a receiving spring 151 is fixedly connected to the bottom wall of the receiving groove 15, a receiving plate 152 is fixedly connected to the surface of the receiving spring 151 away from the bottom wall of the receiving groove 15, and the receiving spring 151 drives the receiving plate 152 to protrude from the receiving groove 15. When the receiving plate 152 is located in the receiving groove 15, the receiving spring 151 is in a compressed state.

[0041] Reference Figure 3 and Figure 4 A fire extinguishing bag 153 is placed on the receiving plate 152. The fire extinguishing bag 153 includes a potassium powder fire extinguishing agent. The potassium powder fire extinguishing agent can quickly react with oxygen in the air to consume a large amount of oxygen. Two puncture strips 142 are fixedly connected to the surface of the baffle 141. The two puncture strips 142 can cut open the fire extinguishing bag 153. When the baffle 141 blocks the heat dissipation hole 11, the baffle 141 does not block the receiving groove 15.

[0042] Reference Figure 4 A stop hole 143 is provided on the surface of the baffle 141, and a stop plate 144 is rotatably connected to the stop hole 143, and the stop plate 144 can completely block the opening of the stop hole 143. A stop groove 145 is provided on the side of the stop plate 144, and a sliding groove 146 is provided on the surface of the baffle 141. A stop bar 147 is slidably connected in the sliding groove 146, and the stop bar 147 can be inserted into the stop groove 145. When the baffle 141 completely blocks the stop hole 143, the stop bar 147 can be inserted into the stop groove 145. A first magnet 148 is fixedly connected to the end surface of the stop bar 147, and a second magnet 149 is fixedly connected to the bottom wall of the stop groove 145, and the first magnet 148 attracts the second magnet 149. When the stop bar 147 is inserted into the stop groove 145 , the first magnet 148 attracts the second magnet 149 , so that the stop bar 147 is fixed on the stop plate 144 .

[0043] Reference Figure 3 and Figure 4 When the baffle 141 blocks the heat dissipation hole 11, the puncture strip 142 slides in the receiving groove 15, allowing the puncture strip 142 to cut the fire extinguishing bag 153, and the receiving spring 151 pushes the fire extinguishing bag 153 to protrude from the receiving groove 15 through the receiving plate 152, so that the fire extinguishing bag 153 covers the placement groove 12, allowing the potassium powder fire extinguishing agent to consume a large amount of oxygen, thereby reducing the oxygen in the placement groove 12, thereby suppressing the flame.

[0044] Reference Figure 2 and Figure 5The box body 1 is provided with a moving assembly 16, which includes a moving bar 161, a moving spring 162 and a moving block 163. The moving bar 161 is slidably connected to the groove wall of the placement groove 12. Both ends of the moving spring 162 are fixedly connected with a rotating block 164, one of which is rotatably connected to the end surface of the moving bar 161 away from the bottom wall of the placement groove 12, and the other rotating block 164 is rotatably connected to the end surface of the moving block 163.

[0045] Reference Figure 5 , a limiting strip 165 is fixedly connected to the surface of the moving block 163 facing the moving bar 161, and the limiting strip 165 extends along the length direction of the moving bar 161. A limiting groove 166 for inserting the limiting strip 165 is provided on the surface of the moving bar 161 facing the moving block 163. When the limiting strip 165 is inserted into the limiting groove 166, the moving block 163 moves toward the moving bar 161, and the moving spring 162 is in a compressed state at this time; when the limiting strip 165 abuts against the end surface of the moving bar 161 facing the moving block 163, the moving spring 162 is in a non-stressed state.

[0046] Reference Figure 1 and Figure 6 A plurality of through holes 21 are formed on the surface of the door 2 , and fixing strips 22 are slidably connected in the plurality of through holes 21 .

[0047] Reference Figure 3 , Figure 5 and Figure 6 The moving bar 161 is located on the moving path of the baffle 141. When the baffle 141 blocks the heat dissipation hole 11, the baffle 141 pushes the moving bar 161 to move toward the door 2, so that the moving block 163 is inserted into the through hole 21. At this time, the fixed bar 22 protrudes from the door 2, and the door 2 is difficult to rotate.

[0048] Reference Figure 5 and Figure 6 The end surface of the fixed bar 22 facing the moving block 163 is fixedly connected with the fixed block 23, and the fixed block 23 extends along the length direction of the fixed bar 22. The end surface of the moving block 163 away from the moving bar 161 is provided with a fixed groove 24 for inserting the fixed block 23. When the fixed block 23 is inserted into the fixed groove 24, the fixed bar 22 and the moving block 163 are fixed to each other, and at this time, the staff can drive the moving block 163 to move through the fixed bar 22.

[0049] Reference Figure 5 and Figure 6, the staff rotates and presses the fixing bar 22 to insert the fixing block 23 into the fixing groove 24, and then continues to rotate the fixing bar 22 to allow the fixing bar 22 to drive the moving block 163 to rotate, so that the limiting bar 165 is smoothly inserted into the limiting groove 166, so that the moving block 163 can be separated from the through hole 21, so that the staff can open the box door 2, and the staff can extinguish the fire point at this time.

[0050] The implementation principle of a photovoltaic prefabricated cabin in an embodiment of the present application is as follows: when a fire occurs inside the box body 1, the temperature sensor 13 detects abnormal temperature, and the temperature sensor 13 drives the driving cylinder to start, so that the driving cylinder drives the baffle 141 to block the heat dissipation hole 11. At this time, the baffle 141 drives the piercing strip 142 to move and cut the fire extinguishing bag 153. The baffle 141 does not block the opening of the accommodating groove 15, so that the accommodating spring 151 drives the fire extinguishing bag 153 to move into the placement groove 12, so that the fire extinguishing bag 153 can absorb the oxygen in the placement groove 12 and reduce the possibility of fire spreading; at the same time, the baffle 141 drives the moving strip 161 to move, so that the moving block 163 is inserted into the through hole 21. At this time, the moving block 163 pushes the fixed strip 22 to protrude from the box door 2, thereby preventing outsiders from accidentally opening the box door 2 and causing oxygen to be refilled into the placement groove 12.
