In addition, the equipment components inside the distribution cabinet will generate heat during operation. Direct contact of the fire with the distribution cabinet body will also cause the temperature inside the distribution cabinet to gradually rise. When the temperature of the equipment components reaches a certain value, the equipment components with too high temperature are prone to malfunction or damage, thereby causing greater economic losses.

Because the bottom end of the outer wall of the fireproof shell 4 is located in the water storage shell 2, the circular grooves 7 on both sides of the bottom of the fireproof shell 4 are located in the water, so that the two groups of circular grooves 7 and the square grooves 8 form a connected fluid system. At this time, the rotating plate 11 rotates, which will exert a force on the water molecules near it. This force will change the motion state of the water molecules, that is, give the water molecules a momentum. According to the law of conservation of momentum, the change of momentum inside a system The rotation of the rotating plate 11 will also change the pressure in the two groups of circular grooves 7, so that water is sucked out from one group of circular grooves 7, and then moved to the other group of circular grooves 7 through the square grooves 8, forming a circulating water cycle, so that the heat can be taken away during the water circulation, and the heat is not easily transferred to the cabinet 1, so that the device has a better fire prevention effect when encountering a fire, so that the cabinet 1 will not only not be directly exposed to the fire, but also the heat is not easily transferred to the cabinet 1, so that the cabinet 1 is better protected.

[0020] A pair of connecting pipes 13 are fixedly connected to the top of the outer wall of the fireproof shell 4, and the pair of connecting pipes 13 are connected to the square groove 8; an annular water storage shell 14 is fixedly connected to the top of the outer wall of the pair of connecting pipes 13, and the pair of connecting pipes 13 are connected to the annular water storage shell 14; a group of water nozzles 15 are provided on the outer side wall of the annular water storage shell 14, and a group of water nozzles 15 are connected to the annular water storage shell 14. When water forms a water cycle in the circular groove 7, the square groove 8 and the water storage shell 2, because the connecting pipe 13 is connected to the square groove 8, water will also enter through the connecting pipe 13. The water flows into the annular water storage shell 14, and then a group of water nozzles 15 on the annular water storage shell 14 spray water out, which has the effect of extinguishing the fire and makes it difficult for the fire to spread. The water sprayed by the water nozzles 15 can cool the surroundings and the fireproof shell 4, so that the temperature of the surroundings and the fireproof shell 4 can be effectively controlled, so that the heat can be controlled, and the temperature rise of the cabinet 1 can be controlled, so that the temperature of the equipment components in the cabinet 1 is not easy to be too high, and the fire can be controlled, so that the threat of the cabinet 1 and the fireproof shell 4 can be reduced, so that the cabinet 1 can be effectively protected.

[0021] The annular water storage shell 14 includes an upper shell 141 and a lower shell 142; the bottom end of the outer wall of the upper shell 141 is sealed and rotatably connected to the top of the outer wall of the lower shell 142; a group of water nozzles 15 are arranged on the outer wall of the upper shell 141; the lower shell 142 is fixedly connected to the connecting pipe 13; the outer wall of one end of the rotating shaft 10 located outside the fireproof shell 4 is fixedly connected to the first gear 24; the top of the outer wall of the fireproof shell 4 is rotatably connected to the rotating rod 25; the top of the outer wall of the rotating rod 25 is fixedly connected to the second gear 26, and the second gear 26 is meshed with the first gear 24; the inner wall of the upper shell 141 is fixedly connected to the annular rack 27, and the annular rack 27 is meshed with the second gear 26. When the motor 9 When the rotating shaft 10 is driven to rotate, the rotation of the rotating shaft 10 drives the first gear 24 to rotate. Since the first gear 24 and the second gear 26 are meshed with each other, the first gear 24 drives the second gear 26 and the rotating rod 25 to rotate. Since the second gear 26 is meshed with the annular rack 27, the rotation of the second gear 26 drives the annular rack 27 and the upper shell 141 to rotate, so that the water sprinkler 15 on the upper shell 141 rotates while spraying water, so that the sprayed water can be sprayed farther under the action of the rotational force, so that the range of spraying cooling and fire control of the device is increased, so that fire and temperature are less likely to approach the cabinet 1, and the safety of the cabinet 1 is further improved.

[0022] The outer wall of the connecting pipe 13 is fixedly connected with a square shell 16, and the square shell 16 is connected with the connecting pipe 13; a sealing block 17 is fixedly connected to one side of the inner wall of the square shell 16 through a first spring, and the sealing block 17 matches the square shell 16 and the connecting pipe 13; a slope 18 is provided at one side corner of the bottom end of the outer wall of the sealing block 17, and the slope 18 matches the connecting pipe 13. When water enters the square groove 8 and the connecting pipe 13, the sealing block 17 will block the connecting pipe 13 under the elastic force of the first spring, so that the connecting pipe 13 is in a sealed state, so that when the rotating plate 11 rotates, Water is more easily sucked, so that the speed of water forming a water circulation is not easy to decrease, and when the water circulation is formed, the water will rush into the connecting pipe 13. Because a slope 18 is provided at a corner of one side of the bottom end of the outer wall of the sealing block 17, when the water impacts the slope 18, the slope 18 of the sealing block 17 will drive the sealing block 17 and the first spring to expand and contract under the action of the impact force, so that the connecting pipe 13 is released from the sealed state and connected to the annular water storage shell 14, so that the device can not only ensure the speed of water forming a water circulation, but also enable the water nozzle 15 to operate normally.

[0023] The outer wall of the lower shell 142 is fixedly connected to the third bevel gear 28; one end of the outer wall of a group of water sprinklers 15 is rotatably connected to the outer wall of the upper shell 141; the outer wall of a group of water sprinklers 15 is fixedly connected to the fourth bevel gear 29, and a group of fourth bevel gears 29 are meshed with the third bevel gear 28; a pair of auxiliary sprinklers 30 are fixedly connected to the outer wall of the water sprinkler 15, and the pair of auxiliary sprinklers 30 are connected to the water sprinkler 15; the pair of auxiliary sprinklers 30 are inclined, and the pair of auxiliary sprinklers 30 are symmetrical about the center line of the water sprinkler 15. When the water sprinkler 15 and the upper shell 141 rotate, because the outer wall of the lower shell 142 is fixedly connected to the third bevel gear 28 and the outer wall of a group of water sprinklers 15 is fixedly connected to the fourth bevel gear 29, and a group of The four bevel gears 29 are all meshed with the third bevel gear 28, so that when the water sprinkler 15 rotates, the fourth bevel gear 29 will move in the tooth groove of the third bevel gear 28, so that the fourth bevel gear 29 will rotate while moving along the tooth groove of the third bevel gear 28, so that the fourth bevel gear 29 drives the water sprinkler 15 to rotate, and the pair of auxiliary sprinkler heads 30 on the water sprinkler 15 rotates. When the pair of auxiliary sprinkler heads 30 rotates, the rotation of the auxiliary sprinkler heads 30 will change the angle of the auxiliary sprinkler heads 30, so that the auxiliary sprinkler heads 30 can not only spray to nearby places, but also to distant places, so that the auxiliary sprinkler heads 30 can cooperate with the water sprinkler heads 15 to expand the spraying range, and the spraying water potential will also be enhanced, so that the fire prevention effect of the present device is further improved.

[0024] A first through slot 19 is provided on one side of the outer wall of the square shell 16; a circular shell 20 is fixedly connected to one side of the outer wall of the square shell 16, and the circular shell 20 is connected to the first through slot 19; a blocking block 21 is fixedly connected to one side of the inner wall of the circular shell 20 through a second spring; a stretching rod 22 is fixedly connected to one end of the outer wall of the blocking block 21, and one end of the outer wall of the stretching rod 22 passes through the circular shell 20; a blocking groove 23 is provided on the outer side wall of the sealing block 17, and the blocking groove 23 matches the blocking block 21. When the sealing block 17 contracts under the impact force of water, when the blocking groove 23 on the sealing block 17 moves to the position of the blocking block 21, the blocking block 21 will be stuck in the blocking groove 23 under the elastic force of the second spring. The sealing block 17 is fixed so that when the subsequent water sprinkler 15 sprays water, the sealing block 17 will no longer block the connecting pipe 13. When the water pressure is reduced, the fixed sealing block 17 cannot block the connecting pipe 13. When the sealing block 17 is needed to block the connecting pipe 13, the stretching rod 22 is pulled so that the stretching rod 22 drives the blocking block 21 to move out of the blocking groove 23. At this time, the unfixed sealing block 17 will block the connecting pipe 13 again under the action of the first spring. Therefore, when the device needs to spray water, the sealing block 17 can be fixed, so that the water is not easily interrupted, so that the water sprinkler 15 can continue to spray water, and the fire prevention effect of the device is more stable and effective.

[0025] Embodiment 2:

[0026] See also Figure 7-Figure 8As shown, the connecting pipe 13 includes a first round tube 131 and a second round tube 132; the bottom end of the outer wall of the first round tube 131 is fixedly connected to the top end of the outer wall of the fireproof shell 4; the inner wall of the second round tube 132 is sealed and slidably connected to the outer wall of the first round tube 131; one end of the outer wall of the square shell 16 is fixedly connected to the outer wall of the first round tube 131; the top end of the outer wall of the second round tube 132 is fixedly connected to the bottom end of the outer wall of the lower shell 142; the outer wall of the rotating rod 25 is fixedly connected to the fifth bevel gear 31; the fireproof shell 4 The top of the outer wall of is rotatably connected to the first rotating rod 32 through the first square plate; the sixth bevel gear 33 is fixedly connected to one end of the outer wall of the first rotating rod 32, and the sixth bevel gear 33 is meshed with the fifth bevel gear 31; the other end of the outer wall of the first rotating rod 32 is fixedly connected to an elliptical block 34, and the outer side wall of the elliptical block 34 is in contact with the bottom end of the outer wall of the second circular tube 132. When the rotating rod 25 rotates, the rotation of the rotating rod 25 will drive the fifth bevel gear 31 to rotate, because the fifth bevel gear 31 and the sixth bevel gear 33 are meshed with each other. The first rotating rod 32 is meshed with each other, so that the fifth bevel gear 31 drives the first rotating rod 32 to rotate through the sixth bevel gear 33, and the rotation of the first rotating rod 32 drives the elliptical block 34 to rotate. Because the inner side wall of the second circular tube 132 is sealed and slidably connected to the outer side wall of the first circular tube 131 and the outer side wall of the elliptical block 34 is in contact with the outer wall bottom end of the second circular tube 132, when the elliptical block 34 rotates, it will drive the second circular tube 132 to move up and down, so that the second circular tube 132 drives the annular water storage shell 14 and the water sprinkler 15 to move up and down, so that the up and down movement of the water sprinkler 15 drives the water sprayed by the water sprinkler 15 to change the water flow direction, so that when there is an obstacle in front, the water flow direction of the sprayed water can be changed by the shaking generated by the up and down movement, and the water flow direction can be adjusted to make the water flow bypass the obstacle, so that the obstacle cannot hinder the water sprayed by the water sprinkler 15, so that the fire prevention effect of the device is further improved, and the device can still play the role of fire prevention, cooling and fire control when there is an obstacle.

[0027] The outer wall of the second circular tube 132 is provided with a pair of support plates 35, and the support plates 35 are U-shaped; the two ends of the outer wall of the pair of support plates 35 are respectively fixed to the outer wall of the pair of second circular tubes 132, and the pair of support plates 35 are symmetrical about the center line of the second circular tube 132; the top of the outer wall of the pair of support plates 35 is fixed to a pair of support rods 36, and the top of the outer wall of the two pairs of support rods 36 is fixed to the bottom end of the outer wall of the lower shell 142. When the second circular tube 132 drives the annular water storage shell 14 to move up and down, because the two ends of the outer wall of the pair of support plates 35 are respectively fixed to the outer wall of the pair of second circular tubes 132, a second When the circular tube 132 moves, it will drive a pair of support plates 35 and another second circular tube 132 to move, thereby making the up and down movement of the annular water storage shell 14 more convenient and less prone to malfunction. A pair of support rods 36 are fixedly connected to the top ends of the outer walls of the pair of support plates 35, and the top ends of the outer walls of the two pairs of support rods 36 are fixedly connected to the bottom ends of the outer walls of the lower shell 142, so that the annular water storage shell 14 has multiple force points when it moves up and down, thereby reducing the pressure and load of the second circular tube 132, making the up and down movement of the annular water storage shell 14 more convenient and flexible, and also making the movement of the annular water storage shell 14 less likely to impose a heavy burden on other mechanisms.

Because the bottom end of the outer wall of the fireproof shell 4 is located in the water storage shell 2, the circular grooves 7 on both sides of the bottom end of the fireproof shell 4 are located in the water, so that the two groups of circular grooves 7 and the square grooves 8 form a connected fluid system. At this time, the rotating plate 11 rotates, which will exert a force on the water molecules near it, and this force will change the motion state of the water molecules, that is, give the water The momentum of a molecule. According to the law of conservation of momentum, the change in momentum within a system must be equal to the sum of the impulses of all external forces acting on the system. In this case, the force exerted by the rotation of the rotating plate 11 on the water molecules is the external force, which will cause the water molecules to gain momentum and start to move. The rotation of the rotating plate 11 will also change the pressure in the two groups of circular grooves 7, so that water is sucked out of one group of circular grooves 7 and then moves to the other group of circular grooves 7 through the square grooves 8, forming a circulating water cycle, so that the water can take away heat during the circulation, making it difficult for the heat to be transferred to the cabinet 1, so that the device has a better fireproof effect when encountering a fire, so that the cabinet 1 will not only not directly contact the fire, but also the heat will not be easily transferred to the cabinet 1, so that the cabinet 1 is better protected, and when the water When water circulation is formed in the circular groove 7, the square groove 8 and the water storage shell 2, because the connecting pipe 13 is connected with the square groove 8, water will also enter the annular water storage shell 14 through the connecting pipe 13, so that the water is sprayed out through a group of water nozzles 15 on the annular water storage shell 14, which has the effect of extinguishing the fire and makes it difficult for the fire to spread. The water sprayed by the water nozzle 15 can cool the surroundings and the fireproof shell 4, so that the temperature of the surroundings and the fireproof shell 4 can be effectively controlled, so that the heat can be controlled, and the temperature rise of the cabinet 1 can be controlled, so that the temperature of the equipment components in the cabinet 1 is not easy to be too high, and the fire can be controlled, so that the threat of the cabinet 1 and the fireproof shell 4 can be reduced, so that the cabinet 1 can be effectively protected, and when the water is submerged in the square groove 8 and the connecting pipe 13, the sealing block 17 will block the connecting pipe 13 under the elastic force of the first spring, so that the connecting pipe 13 is in a sealed state, so that when the rotating plate 11 rotates, water is more easily sucked, so that the speed of water forming a water circulation is not easy to reduce, and when the water circulation is formed, the water will rush into the connecting pipe 13, because the outer wall bottom end of the sealing block 17 is provided with a slope 18 at one side corner, when the water impacts the slope 18, the slope 18 of the sealing block 17 will drive the sealing block 17 and the first spring to expand and contract under the action of the impact force, so that the connecting pipe 13 is released from the sealed state and connected to the annular water storage shell 14, so that the device can not only ensure the speed of water forming a water circulation, but also enable the water nozzle 15 to operate normally, and when the sealing block 17 contracts under the impact force of water,When the locking groove 23 on the sealing block 17 moves to the position of the locking block 21, the locking block 21 will be locked into the locking groove 23 under the elastic force of the second spring, and the sealing block 17 will be fixed, so that when the subsequent water sprinkler 15 sprays water, the sealing block 17 will no longer block the connecting pipe 13, so that when the water pressure is reduced, the fixed sealing block 17 cannot block the connecting pipe 13 either. When the sealing block 17 needs to be used to block the connecting pipe 13, the stretching rod 22 is pulled so that the stretching rod 22 drives the locking block 21 to move out of the locking groove 23. At this time, the unfixed sealing block 17 will re-block the connecting pipe 13 under the action of the first spring, so that the sealing block 17 can be fixed when the device needs to spray water, so that the water is not easily interrupted, so that the water sprinkler 15 can be maintained The water is continuously sprayed, so that the fire prevention effect of the device is more stable and effective, and when the motor 9 drives the rotating shaft 10 to rotate, the rotation of the rotating shaft 10 drives the first gear 24 to rotate. Because the first gear 24 and the second gear 26 are meshed with each other, the first gear 24 drives the second gear 26 and the rotating rod 25 to rotate. Because the second gear 26 and the annular rack 27 are meshed with each other, the rotation of the second gear 26 drives the annular rack 27 and the upper shell 141 to rotate, so that the water nozzle 15 on the upper shell 141 rotates while spraying water, so that the sprayed water can be sprayed farther under the action of the rotation force, so that the spraying cooling and fire control range of the device is increased, so that the fire and temperature are less likely to approach the cabinet 1, and the safety of the cabinet 1 is further improved. When the water sprinkler 15 and the upper shell 141 rotate, because the outer side wall of the lower shell 142 is fixedly connected with the third bevel gear 28 and the outer side wall of a group of water sprinkler 15 is fixedly connected with the fourth bevel gear 29, and a group of fourth bevel gears 29 are meshed with the third bevel gear 28, when the water sprinkler 15 rotates, the fourth bevel gear 29 will move in the tooth groove of the third bevel gear 28, so that the fourth bevel gear 29 will move while moving along the tooth groove of the third bevel gear 28, so that the fourth bevel gear 29 drives the water sprinkler 15 to rotate, so that the pair of auxiliary sprinkler heads 30 on the water sprinkler 15 rotates. When the pair of auxiliary sprinkler heads 30 rotates, the rotation of the auxiliary sprinkler heads 30 will change the angle of the auxiliary sprinkler heads 30, so that the auxiliary sprinkler heads 30 can not only spray to nearby places , and it can also be sprayed to a distant place, so that the auxiliary nozzle 30 cooperates with the water nozzle 15 to expand the spraying range, and the spraying water potential will also be enhanced, so that the fire prevention effect of the device is further improved, and when the rotating rod 25 rotates, the rotation of the rotating rod 25 will drive the fifth bevel gear 31 to rotate. Because the fifth bevel gear 31 and the sixth bevel gear 33 are meshed with each other, the fifth bevel gear 31 drives the first rotating rod 32 to rotate through the sixth bevel gear 33, and the rotation of the first rotating rod 32 drives the elliptical block 34 to rotate. Because the inner side wall of the second circular tube 132 is sealed and slidably connected to the outer side wall of the first circular tube 131 and the outer side wall of the elliptical block 34 is in contact with the bottom end of the outer wall of the second circular tube 132, when the elliptical block 34 rotates, it will drive the second circular tube 132 to move up and down,Thereby, the second circular tube 132 drives the annular water storage shell 14 and the water sprinkler 15 to move up and down, so that the up and down movement of the water sprinkler 15 drives the water sprayed by the water sprinkler 15 to change the direction of the water flow, so that when there is an obstacle in front, the water flow direction of the sprayed water can be changed by the shaking generated by the up and down movement. The water flow direction can be adjusted to make the water flow bypass the obstacle, so that the obstacle cannot hinder the water sprayed by the water sprinkler 15, so that the fire prevention effect of the device is further improved, and the device can still play the role of fire prevention, cooling and controlling the fire when there are obstacles. When the second circular tube 132 drives the annular water storage shell 14 to move up and down, because the two ends of the outer wall of the pair of support plates 35 are respectively fixed to the outer side walls of the pair of second circular tubes 132, a pair of When the second circular tube 132 moves, it will drive a pair of support plates 35 and another second circular tube 132 to move, so that the up and down movement of the annular water storage shell 14 is more convenient and less prone to failure. A pair of support rods 36 are fixedly connected to the top of the outer wall of the pair of support plates 35, and the top of the outer wall of the two pairs of support rods 36 are fixedly connected to the bottom of the outer wall of the lower shell 142, so that the annular water storage shell 14 has multiple force points when moving up and down, thereby reducing the pressure and load of the second circular tube 132, making the up and down movement of the annular water storage shell 14 more convenient and flexible, and making the movement of the annular water storage shell 14 less likely to cause a large burden on other mechanisms, so that the service life of the mechanisms and parts in the device is increased, and the probability of damage to the parts in the device is reduced.
