[0020] 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.

[0021] Example 1: Figure 1-Figure 5As shown, a mobile transformer with an explosion-proof protection mechanism includes a transformer 100, a heat dissipation mesh slot 101, two fixing frames 103, two sponge sheets 104, a heat dissipation mechanism 110, a water storage mechanism 130, two groups of liquid spraying mechanisms 120 and a linkage mechanism 140.

[0022] A heat dissipation port is provided on the back of the transformer 100, an opening is provided on the top of the transformer 100, and a heat dissipation mesh slot 101 is installed on the heat dissipation port; two fixing frames 103 are respectively installed on the two side surfaces of the transformer 100; two sponge sheets 104 are respectively installed in the two fixing frames 103, and the two sponge sheets 104 are in contact with the transformer 100; a heat dissipation mechanism 110 is installed on the top of the transformer 100, and the heat dissipation mechanism 110 is connected to the inside of the transformer 100, and the heat dissipation mechanism 110 is used to speed up the air flow speed inside the transformer 100; a water storage mechanism 130 is installed on the top of the heat dissipation mechanism 110, and water is contained in the water storage mechanism 130; a liquid spraying mechanism 120 is used to spray the water in the water storage mechanism 130 on the surface of the sponge sheet 104.

[0023] Specifically, when the transformer 100 needs to be cooled, the heat dissipation mechanism 110 is started to allow outside air to enter the transformer 100 through the heat dissipation mesh slot 101, so that the hot air in the transformer 100 is discharged, thereby accelerating the air circulation and facilitating the reduction of the temperature inside the transformer 100.

[0024] When the heat dissipation mechanism 110 is in operation, the two groups of spray mechanisms 120 will be driven to operate through the linkage mechanism 140, so that the spray mechanisms 120 draw out the water in the water storage mechanism 130 and spray it on the surface of the sponge sheet 104. Since the sponge sheet 104 is in contact with the surface of the transformer 100, when the water on the sponge sheet 104 evaporates, it will take away the heat from the surface of the transformer 100, thereby facilitating cooling of the transformer 100.

[0025] like Figure 5 As shown, the heat dissipation mechanism 110 includes a box 111, an air outlet 114, a motor 115, a shaft 116 and a fan blade 117. The box 111 is installed on the top surface of the transformer 100, and the box 111 is connected to the inside of the transformer 100; the air outlet 114 is installed on the side of the box 111; the motor 115 is installed in the box 111; the shaft 116 is fixedly connected to the power output shaft of the motor 115; the fan blade 117 is located in the air outlet 114, and the fan blade 117 is installed on the shaft 116.

[0026] Specifically, when the motor 115 is running, the power output shaft of the motor 115 will drive the fan blades 117 to rotate, and the rotating fan blades 117 will blow out the air in the box 111. Since the box 111 is connected to the inside of the transformer 100, the hot air in the transformer 100 will enter the box 111. The rotating fan blades 117 will blow out the hot air in the transformer 100, so that the outside air enters the transformer 100, thereby accelerating the air flow speed inside and outside the transformer 100.

[0027] like Figure 1-Figure 3 As shown, the water storage mechanism 130 includes a water tank 131, a water inlet pipe 132 and a drain pipe 133. The water tank 131 is placed on the top surface of the transformer 100; the bottom surface of the water tank 131 is provided with a storage groove, the size of which matches the water tank 131 and the transformer 100, the transformer 100 can be placed in the storage groove, and the top of the water tank 131 can be placed in the storage groove. The water inlet pipe 132 is installed on the water tank 131; the drain pipe 133 is installed on the side of the water tank 131.

[0028] Specifically, water can be added into the water tank 131 through the water inlet pipe 132. The water in the water tank 131 can be drained through the drain pipe 133.

[0029] like Figure 3 and Figure 4 As shown, the liquid spraying mechanism 120 includes a vertical pipe 121, a plurality of atomizing nozzles 122, a piston cylinder 123, a piston rod 126, a push plate 127 and a spring 128. The vertical pipe 121 is plugged into the first plug-in tube 105 installed on the fixed frame 103; multiple atomizing nozzles 122 are installed on the vertical pipe 121, and the multiple atomizing nozzles 122 are all facing the sponge sheet 104; the piston cylinder 123 is installed on the side of the box body 111, and the top surface of the piston cylinder 123 is provided with a suction tube 124 and a liquid infusion tube 125, the other end of the suction tube 124 is plugged into the water tank 131, and the other end of the liquid infusion tube 125 is plugged into the vertical pipe 121, and a piston sheet is slidably connected in the piston cylinder 123; both the suction tube 124 and the liquid outlet tube are installed with a one-way valve, so that the water in the piston cylinder 123 can only enter the vertical pipe 121 in one direction through the liquid infusion tube 125, and the water in the water tank 131 can only enter the piston cylinder 123 in one direction through the suction tube 124. The piston rod 126 is fixedly connected to the piston plate, and the piston rod 126 is slidably connected to the piston cylinder 123; the push plate 127 is fixedly connected to one end of the piston rod 126 away from the piston cylinder 123; one end of the spring 128 is connected to the push plate 127, and the other end of the spring 128 is connected to the piston cylinder 123.

[0030] Specifically, when the push plate 127 moves upward, it will drive the piston rod 126 and the piston plate to move upward, and then transport the water in the piston cylinder 123 to the vertical pipe 121 through the infusion tube 125, and the water in the vertical pipe 121 will be sprayed toward the sponge sheet 104 through the atomizing nozzle 122; when the push plate 127 is released, the rebound force of the spring 128 will push the push plate 127 to move downward, and then drive the piston rod 126 and the piston plate to move downward, and then the piston cylinder 123 will draw the water in the water tank 131 into the piston cylinder 123 through the liquid extraction tube 124.

[0031] like Figure 5 As shown, the linkage mechanism 140 includes a reciprocating screw 141, a pinion 142, a large gear 143, a moving seat 144 and two cams 145. The reciprocating screw 141 is rotatably mounted on the housing 111; the pinion 142 is fixedly sleeved on the reciprocating screw 141; the large gear 143 is fixedly sleeved on the shaft 116, and the large gear 143 is meshed with the pinion 142; the moving seat 144 is sleeved on the reciprocating screw 141; when the reciprocating screw 141 rotates, the moving seat 144 will reciprocate horizontally along the reciprocating screw 141. The two cams 145 are respectively mounted at both ends of the reciprocating screw 141, and the two cams 145 are respectively in contact with the two push plates 127.

[0032] Specifically, when the shaft 116 rotates, it will drive the large gear 143 to rotate, and then mesh with the small gear 142 to rotate, and then drive the reciprocating screw 141 to rotate, and then drive the two cams 145 to rotate. The rotating cam 145 will cooperate with the spring 128 to make the push plate 127 move back and forth up and down.

[0033] like Figure 2 and Figure 5 As shown, the heat dissipation mechanism 110 includes a transverse groove 112 and a sealing strip 113. The transverse groove 112 is opened on the back of the box body 111; the sealing strip 113 is installed on the transverse groove 112.

[0034] Specifically, by providing the sealing strip 113 , it is possible to reduce the amount of air entering the box body 111 through the transverse groove 112 .

[0035] like Figure 2 and Figure 5 As shown, the mobile transformer with explosion-proof protection mechanism also includes a cleaning mechanism 150, and the cleaning mechanism 150 includes a bent rod 151 and a cleaning brush 152. The bent rod 151 is slidably connected to the transverse groove 112, and one end of the bent rod 151 is fixedly connected to the movable seat 144; the cleaning brush 152 is installed on the bent rod 151, and the cleaning brush 152 contacts the heat dissipation mesh groove 101.

[0036] Specifically, when the reciprocating screw 141 rotates, it drives the moving seat 144 to move reciprocatingly horizontally, and then drives the bending rod 151 to move reciprocatingly horizontally, so that the cleaning brush 152 cleans the heat dissipation mesh slot 101, thereby preventing dust and debris from clogging the heat dissipation mesh slot 101.

[0037] like Figure 1 , Figure 3 and Figure 6 As shown, the mobile transformer with explosion-proof protection mechanism further includes an explosion-proof protection mechanism 160, and the explosion-proof protection mechanism 160 includes a gas storage tank 161, an exhaust pipe 162, a solenoid valve 163, an air outlet groove 164, a fire detector and a controller.

[0038] The gas tank 161 is installed on the front of the box 111, and the gas tank 161 stores inert gas, such as carbon dioxide, nitrogen, argon or a mixture of multiple inert gases. The exhaust pipe 162 is installed in the gas tank 161, and one end of the exhaust pipe 162 extends to the inside of the transformer 100; the solenoid valve 163 is installed on the exhaust pipe 162; the gas outlet groove 164 is opened on the part of the exhaust pipe 162 located in the transformer 100; the fire detector (not shown) is installed in the transformer 100; the controller (not shown) is installed in the transformer 100, and the controller is electrically connected to the fire detector and the solenoid valve 163. The fire detector is an aspirating smoke detector or a smoke fire detector. The fire detector, the controller and the solenoid valve are existing mature technologies, and their working principles are not repeated here.

[0039] Specifically, when the fire detector detects a fire inside the transformer 100, the solenoid valve 163 is activated through the controller, so that the high-pressure inert gas in the gas tank 161 is transported to the exhaust pipe 162, and then the inert gas is quickly transported to the transformer 100 through the gas outlet groove 164, thereby isolating oxygen to achieve the effect of quickly extinguishing the fire, and also preventing the fire from spreading and causing excessive damage to the inside of the transformer 100, and at the same time preventing the fire from being too large and causing the transformer 100 to explode.

[0040] Working principle: When in use, water is added to the water tank 131 through the water inlet pipe 132. When the inside of the transformer 100 needs to be cooled down, the motor 115 is started, so that the power output shaft of the motor 115 drives the fan blades 117 to rotate, and the rotating fan blades 117 blow out the air in the box 111. Since the box 111 is connected to the inside of the transformer 100, the hot air in the transformer 100 will enter the box 111, and the rotating fan blades 117 will blow out the hot air in the transformer 100, so that the outside air enters the transformer 100, thereby accelerating the air flow speed inside and outside the transformer 100.

[0041] When the shaft 116 rotates, it will drive the large gear 143 to rotate, and then mesh with the small gear 142 to rotate, and then drive the reciprocating screw 141 to rotate, and then drive the two cams 145 to rotate. The rotating cam 145 will cooperate with the spring 128 to make the push plate 127 move back and forth up and down. When the push plate 127 moves back and forth up and down, the water in the water tank 131 will be drawn into the piston cylinder 123, and the water in the piston cylinder 123 will be transported to the vertical pipe 121, so that the water in the vertical pipe 121 is sprayed onto the sponge sheet 104 through the atomizing nozzle 122. Since the sponge sheet 104 is in contact with the surface of the transformer 100, when the water on the sponge sheet 104 evaporates, it will take away the heat from the surface of the transformer 100, thereby facilitating cooling of the transformer 100.

[0042] When the reciprocating screw 141 rotates, it drives the movable seat 144 to move reciprocatingly horizontally, and then drives the bending rod 151 to move reciprocatingly horizontally, so that the cleaning brush 152 cleans the heat dissipation mesh slot 101, thereby preventing dust and debris from clogging the heat dissipation mesh slot 101, allowing air to smoothly enter the transformer 100.

[0043] When the fire detector detects a fire inside the transformer 100, the solenoid valve 163 is activated through the controller, so that the high-pressure inert gas in the gas tank 161 is transported to the exhaust pipe 162, and then the inert gas is quickly transported to the transformer 100 through the gas outlet groove 164, thereby isolating oxygen to quickly extinguish the fire, and also preventing the fire from spreading and causing excessive damage to the inside of the transformer 100, and preventing the transformer 100 from exploding due to excessive fire.

[0044] Example 2: Figure 7 and Figure 8 As shown, in the case where other parts are the same as those of Example 1, the difference between this embodiment and Example 1 is that the water storage mechanism 130 also includes a plurality of moving wheels 134 and two second insert cylinders 135. The plurality of moving wheels 134 are installed on the top surface of the water tank 131; the two second insert cylinders 135 are installed on the side of the water tank 131, and the vertical pipe 121 is plugged into the second insert cylinder 135. Reinforcement ribs are provided inside the water tank 131 to improve the anti-deformation ability of the water tank 131.

[0045] Working principle: When the transformer 100 needs to be moved, the water in the water tank 131 is drained by opening the drain pipe 133 of the water tank 131.

[0046] Then, the water tank 131 is removed from the box body 111, and the water tank 131 is turned over so that the multiple moving wheels 134 are facing downward. Then, the infusion tube 125 is separated from the vertical pipe 121, and then the vertical pipe 121 is moved upward to separate the vertical pipe 121 from the first insertion tube 105, and then the two vertical pipes 121 are inserted into the two second insertion tubes 135, so that the water tank 131 and the two vertical pipes 121 form a temporary cart.

[0047] Then, by moving the fixing frame 103 upward, the transformer 100 is lifted and placed on the water tank 131, so that the transformer 100 is easy to be pushed, and the deployment of the transformer 100 in different scenarios is more flexible, and it can quickly respond to various needs, thereby improving the flexibility of the device.
