[0016] The present invention provides a cooling device for a power cabinet, which has the following beneficial effects:

[0017] (1) According to the present invention, when it is necessary to cool down the middle combination position of the modular cabinet, the reciprocating cylinder is started to enable the piston plate to move back and forth in the air collecting box, so that the fixed pipe can absorb the hot air in the middle position of the modular cabinet and discharge it through the one-way valve, thereby facilitating the heat dissipation of the middle combination position in the modular cabinet and improving the heat dissipation efficiency; and through the cooperation of the transmission plate, connecting spring, rotating rod, shielding plate, extrusion disk, limiting hole, block, connecting rod, push plate and reset spring, the shielding plate can shield the fixed pipe when the piston plate moves downward, thereby preventing the hot air sucked from the cabinet from remaining in the air collecting box and preventing the hot air from being discharged from the fixed pipe into the cabinet, thereby reducing the heat dissipation effect.

[0018] (2) According to the present invention, when the card block moves downward, the card block will drive the fixed plate to move downward, so that the protrusion of the extrusion block will squeeze the groove of the side wall of the disturbance plate, thereby driving the disturbance plate to swing in the cooling pipe, which can block the coolant in the cooling pipe, so that the liquid in the cooling pipe can stay in the cooling pipe for a longer time, thereby effectively taking away the heat in the cabinet and improving the cooling efficiency; and when the disturbance plate swings, the swinging plate will squeeze the semicircular block, so that the semicircular block can drive the connecting column to move in the rotation, and the protruding block on the outer wall of the connecting column moves in the spiral groove, so that the rotating shaft can drive the stirring plate to rotate, thereby driving the stirring plate to rotate in the cooling pipe, stirring the coolant far away from the combined cabinet to the place close to the combined cabinet, so as to achieve better heat dissipation effect and prevent the temperature of the coolant near the combined cabinet from rising, which is inconvenient for subsequent cooling operations.

[0019] (3) In the present invention, when the rotating shaft rotates, the cam is driven to rotate. When the end of the cam with a smaller radius rotates to the top of the rotating shaft, the cam will squeeze the push rod, causing the push rod to move outside the cooling pipe. Through the cooperation of the moving plate, the transmission spring, the L-shaped transmission plate, the inclined block, the arc block, the knocking block and the knocking spring, the knocking block can knock the outer wall of the cooling pipe to knock the dust on the outer wall of the cooling pipe off, thereby preventing the outer wall of the cooling pipe from adhering to dust, which will affect the heat dissipation in the cooling pipe and the cooling effect on the cabinet.

DETAILED DESCRIPTION

[0032] 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.

[0033] See also Figure 1-Figure 11One embodiment of the present invention is: a cooling device for a power cabinet, comprising a base 1 and a combined cabinet 2, the combined cabinet 2 is fixed on the top of the base 1, a water pump 4 is fixed on the side wall of the combined cabinet 2, a cooling pipe 5 is attached to the outer wall of the combined cabinet 2, one side of the water pump 4 is connected to the base 1, the other side of the water pump 4 is connected to the cooling pipe 5 through a water pipe, the side of the cooling pipe 5 away from the water pump 4 is connected to the top of the base 1 through a water inlet pipe, a heat dissipation hole 3 is opened on the side wall of the combined cabinet 2, and the combined cabinet 2 An air intake component with better heat dissipation effect is arranged on the top, wherein the air intake component includes a fixed pipe 7, an air collecting box 6, a reciprocating cylinder 8, a piston plate 9, a one-way valve 10, a transmission plate 11, a connecting spring 12, a rotating rod 13, a baffle plate 14, an extrusion disk 15, a limit hole 17, a push plate 20, a block 18, a connecting rod 19 and a reset spring 21; the fixed pipe 7 is fixed to the top of the combined cabinet 2, the air collecting box 6 is fixed to the top of the fixed pipe 7, the reciprocating cylinder 8 is fixed to the top of the air collecting box 6, and the reciprocating cylinder 8 The output end is fixedly connected to the top of the piston plate 9, and the one-way valve 10 is fixed on the right side of the air collecting box 6. The one-way valve 10 can only exhaust air to the outside of the air collecting box 6, so that the air outside the air collecting box 6 cannot enter the air collecting box 6. The rotating rod 13 passes through the fixed pipe 7, and the penetration point is rotatably connected. The baffle plate 14 is fixed to the outer wall of the rotating rod 13, and the extrusion disk 15 is fixed to the end point of the rotating rod 13. The side wall of the extrusion disk 15 is fixed with a torsion spring, and the side of the torsion spring away from the extrusion disk 15 is fixed to the outer wall of the fixed pipe 7. The moving plate 11 passes through the bottom of the air collecting box 6 and is slidably connected at the penetration point. One side of the connecting spring 12 is fixed to the bottom of the air collecting box 6, and the other side of the connecting spring 12 is fixed to the protrusion of the transmission plate 11. The connecting rod 19 passes through the top of the air collecting box 6 and is slidably connected at the penetration point. The block 18 is fixed to the top of the connecting rod 19, one side of the return spring 21 is fixed to the top of the air collecting box 6, and the other side of the return spring 21 is fixed to the inner side of the block 18, and the limiting hole 17 is opened on the outer wall of the extrusion disk 15.

[0034] When it is necessary to cool down the middle combination position of the modular cabinet, by starting the reciprocating cylinder 8, the piston plate 9 can move back and forth in the air collecting box 6, so that the fixed pipe 7 can absorb the hot air in the middle position of the modular cabinet 2 and discharge it through the one-way valve 10, thereby facilitating the heat dissipation of the middle combination position in the modular cabinet and improving the heat dissipation efficiency.

[0035] By setting the baffle plate 14, when the piston plate 9 moves upward to absorb the hot air in the middle of the combined cabinet body 2, the baffle plate 14 is in an open state in the fixed pipe 7. When the piston plate 9 moves downward in the air collecting box 6, the baffle plate 14 blocks the fixed pipe 7 to prevent the hot air sucked out of the combined cabinet body 2 from remaining in the air collecting box 6, and to prevent the hot air from being discharged from the fixed pipe 7 into the combined cabinet body 2.

[0036] When the present embodiment is working, when it is necessary to perform heat dissipation operation on the middle combination position of the combined cabinet body 2, by starting the reciprocating cylinder 8, the output end of the reciprocating cylinder 8 can drive the piston plate 9 to move back and forth in the gas collecting box 6. When the piston plate 9 moves upward, the fixed pipe 7 can adsorb the hot air accumulated in the middle of the combined cabinet body 2 and absorb the hot air into the gas collecting box 6. When the gas enters the gas collecting box 6, the hot air in the gas collecting box 6 is discharged from the one-way valve 10. When the piston plate 9 moves upward to the position corresponding to the one-way valve 10, the hot air in the gas collecting box 6 is discharged from the one-way valve 10. When the push plate 20 makes contact, the piston plate 9 squeezes the push plate 20 and moves upward, driving the connecting rod 19 to move upward, stretching the return spring 21. When the connecting rod 19 moves upward, it drives the card block 18 to move upward, so that the card block 18 is moved out of the limiting hole 17 opened on the outer wall of the extrusion plate 15, thereby releasing the limit of the extrusion plate 15. Because the torsion spring is in a compressed state, the torsion spring can drive the extrusion plate 15 and the rotating rod 13 to rotate, so that the rotating rod 13 drives the shielding plate 14 to rotate, so that the shielding plate 14 blocks the fixed pipe 7. When the cylinder 8 drives the piston plate 9 to move downward in the gas collecting box 6, the piston plate 9 can squeeze the residual gas in the gas collecting box 6 to be discharged from the one-way valve 10, and the fixed pipe 7 is shielded by the shielding plate 14, so that when the piston plate 9 moves downward, the gas is prevented from being discharged from the fixed pipe 7, and when the piston plate 9 moves downward to contact with the transmission plate 11, the piston plate 9 squeezes the transmission plate 11 to move downward, so that the connecting spring 12 is stretched, and when the transmission plate 11 moves downward to contact with the protrusion of the extrusion plate 15 , so that the transmission plate 11 pushes the protrusion of the extrusion disk 15 to rotate, compressing the torsion spring, and when the limiting hole 17 of the extrusion disk 15 rotates to align with the block 18, the return spring 21 is in a stretched state, so that the return spring 21 drives the block 18 to extend into the limiting hole 17, so that the extrusion disk 15 can be fixed, and when the extrusion disk 15 rotates, it can drive the rotating rod 13 to rotate, so that the baffle plate 14 rotates in the fixed tube 7 and is in an open state, so that the next suction operation can be carried out.

[0037] See also Figure 1-Figure 11On the basis of the above embodiment, in another embodiment of the present invention, a disturbance component and a knocking component are provided on the cooling pipe 5, and the disturbance component includes a fixed plate 221, an extrusion block 223, a disturbance plate 222, a rotating shaft 224, a stirring plate 229, a semicircular block 225, a connecting column 226, a return spring 228 and a fixed block 227; the fixed plate 221 is fixed to the side wall of the block 18, the extrusion block 223 is fixed to the bottom of the fixed plate 221, and the disturbance plate 222 is rotatably installed on the inner wall of the cooling pipe 5, and the protrusion of the extrusion block 223 is in contact with the inner wall of the groove of the side wall of the disturbance plate 222, and the rotation The shaft 224 is rotatably mounted on the inner wall of the cooling tube 5, the semicircular block 225 is slidably mounted on the inner wall of the cooling tube 5, the connecting column 226 is fixed on the side wall of the semicircular block 225, one side of the return spring 228 is fixed on the side wall of the semicircular block 225, the fixed block 227 is fixed on the inner wall of the cooling tube 5, and the other side of the return spring 228 is fixed on the side wall of the fixed block 227, a protruding block is fixed on the outer wall of the connecting column 226, a spiral groove is provided on the outer wall of the rotating shaft 224, the protruding block of the connecting column 226 passes through the spiral groove provided on the outer wall of the rotating shaft 224, and the stirring plate 229 is fixed on the outer wall of the rotating shaft 224.

[0038] There are two groups of disturbance plates 222, and the two groups of disturbance plates 222 are symmetrically arranged with the center line of the air collecting box 6 in the vertical direction as the symmetry axis. The disturbance plates 222 swing in the cooling pipe 5, which can block the coolant in the cooling pipe 5, so that the liquid in the cooling pipe 5 can stay in the cooling pipe 5 longer, thereby effectively taking away the heat in the combined cabinet body 2 and improving the cooling efficiency.

[0039] When the disturbance plate 222 swings, the disturbance plate 222 squeezes the semicircular block 225, so that the semicircular block 225 can drive the connecting column 226 to move in the rotating shaft 224, and the raised block on the outer wall of the connecting column 226 moves in the spiral groove, so that the rotating shaft 224 can drive the stirring plate 229 to rotate, thereby driving the stirring plate 229 to rotate in the cooling pipe 5, stirring the coolant away from the combined cabinet body 2 to the place close to the combined cabinet body 2, so as to achieve better heat dissipation effect and prevent the coolant temperature near the combined cabinet body 2 from rising, which is inconvenient for subsequent cooling operations.

[0040] The knocking assembly includes a cam 231, a push rod 232, a moving plate 233, an L-shaped transmission plate 235, a slope block 236, a curved block 237, a transmission spring 234, a knocking spring 239 and a knocking block 238; the cam 231 is fixed to the outer wall of the rotating shaft 224, the push rod 232 passes through the top of the cooling pipe 5, and the penetration is slidably connected, the moving plate 233 is fixed to the top of the push rod 232, one side of the transmission spring 234 is fixed to the top of the cooling pipe 5, and the transmission spring 234 is fixed to the top of the cooling pipe 5. The other side of the movable spring 234 is fixed to the bottom of the movable plate 233, the L-shaped transmission plate 235 is slidably installed on the inner wall of the movable plate 233, one side of the knocking spring 239 is fixed to the inner wall of the movable plate 233, the other side of the knocking spring 239 is fixed to the side wall of the L-shaped transmission plate 235, the inclined block 236 is fixed to the inner side of the L-shaped transmission plate 235, the arc block 237 is fixed to the side wall of the cooling pipe 5, and the knocking block 238 is fixed to the inner side of the L-shaped transmission plate 235.

[0041] There are two groups of knocking blocks 238, and the two groups of knocking blocks 238 are symmetrically arranged with the center line of the air collecting box 6 in the vertical direction as the symmetry axis. When the rotating shaft 224 rotates, the cam 231 is driven to rotate. When the end of the cam 231 with a smaller radius rotates to the top of the rotating shaft 224, the cam 231 will squeeze the push rod 232, so that the push rod 232 moves outside the cooling pipe 5. Through the cooperation of the moving plate 233, the transmission spring 234, the L-shaped transmission plate 235, the inclined block 236, the arc block 237, the knocking block 238 and the knocking spring 239, the knocking block 238 can knock on the outer wall of the cooling pipe 5, knock the dust on the outer wall of the cooling pipe 5 off, and prevent the outer wall of the cooling pipe 5 from adhering to the dust, which will affect the heat dissipation in the cooling pipe 5 and affect the cooling effect of the combined cabinet 2.

[0042] When the embodiment is working, when the block 18 moves downward, the block 18 can drive the fixed plate 221 to move downward. When the fixed plate 221 moves downward, the extrusion block 223 can be driven downward, so that the protrusion of the extrusion block 223 squeezes the inner wall of the groove provided on the side wall of the disturbance plate 222, so that the disturbance plate 222 can swing. When the piston plate 9 moves upward to squeeze the push plate 20, the push plate 20 drives the connecting rod 19 to move upward, so that the connecting rod 19 drives the block 18 to move upward, so that the block 1 8 drives the fixed plate 221 and the extrusion block 223 upward so that the extrusion block 223 squeezes the disturbance plate 222 to reset, and the disturbance plate 222 swings in the cooling pipe 5, so as to block the water flow in the cooling pipe 5, so that the cooling water stays in the cooling pipe 5 for a little longer. When the disturbance plate 222 swings, the end of the disturbance plate 222 squeezes the semicircular block 225, so that the semicircular block 225 is squeezed away from the fixed pipe 7, so that the semicircular block 225 squeezes the return spring 228 to compress. When the semicircular block 225 moves, the connecting column 226 can be driven to move, so that the protruding block fixed on the surface of the connecting column 226 moves in the spiral groove of the rotating shaft 224, so that the protruding block squeezes the spiral groove provided on the outer wall of the rotating shaft 224, and can drive the rotating shaft 224 to rotate, so that the rotating shaft 224 drives the stirring plate 229 to rotate, so that the stirring plate 229 stirs the cooling water in the cooling pipe 5, so that the cooling water far away from the combined cabinet body 2 moves close to the combined cabinet body 2 for cooling. The operation makes the cooling effect better, and when the disturbance plate 222 does not squeeze the semicircular block 225, because the return spring 228 is in a compressed state, the return spring 228 drives the semicircular block 225 to reset, so that the semicircular block 225 drives the connecting column 226 to move, so that the protruding block fixed on the outer wall of the connecting column 226 is reset in the spiral groove, so that the rotating shaft 224 drives the stirring plate 229 to rotate and reset, and the stirring plate 229 rotates back and forth in the cooling pipe 5 through the back and forth rotation of the rotating shaft 224;

[0043] When the rotating shaft 224 rotates, the cam 231 can be driven to rotate. When the end of the cam 231 with a smaller radius rotates to the top of the rotating shaft 224, the cam 231 will squeeze the push rod 232 to move upward, so that the push rod 232 pushes the moving plate 233 to move upward, so that the transmission spring 234 is stretched. When the moving plate 233 moves upward, it can drive the L-shaped transmission plate 235 to move upward, and the inclined surface of the inclined surface block 236 will squeeze the curved surface of the curved surface block 237, so that the inclined surface block 236 will be subjected to the extrusion force, so that the L-shaped transmission plate 235 can be moved away from the fixed pipe 7, and the knocking block 238 can be moved away from the combined cabinet body 2. When the L-shaped transmission plate 235 is away from the fixed pipe 7, the knocking block 238 can be moved away from the combined cabinet body 2. When the pipe 7 is fixed, the knocking spring 239 will be stretched, and when the end with a larger radius of the cam 231 rotates to the top of the rotating shaft 224, the push rod 232 is not squeezed by the cam 231, and the transmission spring 234 is in a stretched state, thereby being able to drive the movable plate 233 to move downward, so that the L-shaped transmission plate 235 moves downward, so that the inclined surface block 236 does not contact the arc surface block 237, so that the inclined surface block 236 is not subject to squeezing force, and because the knocking spring 239 is in a stretched state, the knocking spring 239 can drive the L-shaped transmission plate 235 to reset, so that the knocking block 238 knocks on the outer wall of the cooling pipe 5, knocking the dust attached to the outer wall of the cooling pipe 5 off.

[0044] 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.
