[0020] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0021] See also Figure 1-7 The embodiment of the present invention provides a protection device for power system information equipment, including a power protection cabinet 1, and also includes:

[0022] A square partition 13, the square partition 13 is located in the power protection cabinet 1, and a plurality of square mounting plates 14 are evenly distributed on the square partition 13; and a heat dissipation mechanism, the heat dissipation mechanism is located on the power protection cabinet 1 and connected to the square mounting plates 14;

[0023] Among them, the heat dissipation mechanism includes an air cooling component and a control component, and the air cooling component includes a fan unit, an air inlet pipe 9, an air hole 16 and a delivery pipe 22. The fan unit is located on the power protection cabinet 1, and the air inlet pipe 9 is fixedly installed on the fan unit. The other end of the air inlet pipe 9 is installed through the power protection cabinet 1. The air hole 16 is opened on the square mounting plate 14 and is connected to the air inlet pipe 9 through the delivery pipe 22. The fan unit is also connected to the control component, and the control component is located in the power protection cabinet 1.

[0024] During the use of the equipment, the power protection cabinet 1 is set, wherein the bottom of the power protection cabinet 1 is provided with a steel plate to facilitate the connection of the power protection cabinet 1 with the external structure, and the side wall of the power protection cabinet 1 is provided with a single door 2, which is in a closed state and is connected to the power protection cabinet 1. Sealed connection, a display 3 is also provided on the single door 2, which can be used to monitor and control the electronic equipment in the power protection cabinet 1. A cover plate 4 is provided on the top of the power protection cabinet 1 to prevent the power protection cabinet 1 from being exposed to wind and sun when the power protection cabinet 1 is installed outdoors. During the operation of the equipment in the power protection cabinet 1, the fan unit is started to allow the external natural wind to enter the air inlet pipe 9 after being pressurized, and to be transported to a plurality of delivery pipes 22 through the air inlet pipe 9. The plurality of delivery pipes 22 are respectively connected to the air holes 16 on the plurality of square mounting plates 14, wherein the square mounting plate 14 can be in the form of a square plate, and a mounting hole is opened on the top, so that the electrical equipment can be installed on the square mounting plate 14. At this time, the bottom of the electrical equipment is connected to the air hole 16. When high-pressure air is passed into the air hole 16, the high-pressure air can act directly on the electrical equipment, so that the specific electronic equipment can be fully cooled, the heat dissipation effect is improved, the service life of the equipment is extended, and the probability of fire is reduced as much as possible, which provides convenience for the staff and is worthy of promotion.

[0025] In one embodiment of the present invention, see Figure 1 and Figure 2 , the fan unit comprises:

[0026] The accommodating cylinder A5 is located on the electric power protection cabinet 1. A fan is arranged in the accommodating cylinder A5. The output end of the fan is connected to the air inlet pipe 9.

[0027] An air inlet 7, which is opened on the accommodating tube A5; and a cover A6, which is detachably connected to the accommodating tube A5.

[0028] By setting up a containing cylinder A5, which can adopt a cylindrical structure and be covered by a cover A6, the fan components in the containing cylinder A5 are protected. When the fan is working, external natural wind can be drawn into the containing cylinder A5 through the air inlet 7, wherein a filter is provided on the air inlet 7 to prevent dust from entering the containing cylinder A5. When the air enters the containing cylinder A5 and is pressurized by the fan, it can be transported to the air inlet pipe 9.

[0029] In one embodiment of the present invention, see Figure 3 , and also includes: a connecting notch 17, which is opened on the square partition plate 13; and a groove 15 and a notch 18, which are both opened on the square mounting plate 14, and the groove 15 and the notch 18 are both connected to the air hole 16.

[0030] By setting the groove 15 and the notch 18, wherein the groove 15 is opened in the middle of the square mounting plate 14, when the electrical equipment is installed on the square mounting plate 14 and is tightly attached to the square mounting plate 14, the groove 15 can be connected to the outside through a plurality of notches 18, and the notches 18 are circumferentially distributed on the square mounting plate 14. When the high-pressure air acts on the back of the electrical equipment through the groove 15, the contact area with the electrical equipment can be increased, thereby improving the cooling effect. At the same time, a part of the high-pressure gas will be dispersed to the surroundings through the notch 18, which can disturb the air in the power protection cabinet 1 and increase the fluidity of the air in the power protection cabinet 1, which is beneficial to further improve the heat dissipation effect. Moreover, by setting a plurality of connecting notches 17, the heat generated by the electrical equipment can enter the back of the power protection cabinet 1 through the connecting notch 17 and then be discharged to the outside.

[0031] In one embodiment of the present invention, see Figure 2 , Figure 4 and Figure 6 , the control component comprises:

[0032] A temperature sensing probe 19, which is located in the power protection cabinet 1 and is electrically connected to the fan unit;

[0033] A control cylinder 23, wherein the control cylinder 23 is connected to the inner wall of the power protection cabinet 1 and is connected to the air inlet pipe 9 through a branch pipe 35;

[0034] A control ball 36, wherein the control ball 36 is slidably mounted in the control cylinder 23, and the bottom end of the control ball 36 is connected to the inner wall of the control cylinder 23 via a second spring 34;

[0035] a first sensor 37 , which is located on the inner top wall of the control cylinder 23 and is detachably connected to the control ball 36 ; and a communication port 38 , which is opened on the control cylinder 23 .

[0036] By setting a temperature sensing probe 19, wherein the temperature sensing probe 19 can be in the form of a sensor and a controller, or in the form of a thermistor connected to a circuit, which will not be described in detail here, when the temperature in the power protection cabinet 1 becomes high, the speed of the fan can be increased, thereby increasing the ventilation volume in the power protection cabinet 1, which is beneficial to increase the rate of air exchange, thereby accelerating heat dissipation. When the temperature in the power protection cabinet 1 is too high and the speed of the fan is too large, the high-pressure wind can be delivered to the control cylinder 23 through the branch pipe 35. As the wind force becomes stronger and stronger, the control ball 36 can be blown to overcome the pulling force of the second spring 34 and move upward for a distance. The second spring 34 is connected to the inner wall of the control cylinder 23 through a support rod. When the control ball 36 contacts the first sensor 37, the total circuit in the power protection cabinet 1 can be controlled to be disconnected to avoid excessive temperature. High and safety accidents occur, and after the circuit is disconnected, the fan continues to work, so that the heat in the power protection cabinet 1 can be dissipated to the outside as soon as possible to achieve the purpose of protecting the equipment. At the same time, in the normal heat dissipation process, the air entering the control cylinder 23 can be discharged in time through the connecting port 38. At this time, under the tension of the spring, the control ball 36 is in a shaking state, so that the airflow discharged from the connecting port 38 is in a disorderly state, so as to improve the fluidity of the air in the power protection cabinet 1. Among them, the control ball 36 can be in the form of a foam ball or a rubber ball, which is not specifically limited here. When the control ball 36 is pressed against the first sensor 37, the connecting port 38 can be temporarily closed. Under the push of wind force, the control ball 36 can be continuously pressed against the first sensor 37, thereby ensuring that the circuit is in a disconnected state.

[0037] In one embodiment of the present invention, see Figure 1-4 , further comprising: a smoke probe 20, wherein the smoke probe 20 is located in the power protection cabinet 1;

[0038] A containing tube B11, which is connected to the outer wall of the power protection cabinet 1 and is connected to the air inlet pipe 9 through the air inlet pipe 10; and a starting component, which is located in the power protection cabinet 1 and is respectively connected to the containing tube B11 and the smoke detector 20.

[0039] By means of the smoke probe 20, when a fire occurs in the power protection cabinet 1 due to a circuit fault, the starting component can be activated and the accommodating cylinder B11 can be driven to start working quickly, wherein carbon dioxide gas can be provided in the accommodating cylinder B11, and a sealing cover B12 is provided on the top of the accommodating cylinder B11, which can keep the accommodating cylinder B11 in a sealed state. Driven by the gas pressure, the carbon dioxide gas can enter the delivery pipe 22 through the air inlet pipe 10, and blow onto the square mounting plate 14 respectively, and can fully contact with the equipment on the square mounting plate 14 to maximize the fire extinguishing work, wherein valves are provided on each pipeline to realize the control of the gas flow direction.

[0040] In one embodiment of the present invention, see Figure 4 and Figure 7 , the startup component includes:

[0041] An L-shaped partition 27, wherein the L-shaped partition 27 is connected to the inner wall of the power protection cabinet 1;

[0042] A circulation hole 40, wherein the circulation hole 40 is provided on the L-shaped partition plate 27;

[0043] An air outlet 8, the air outlet 8 is provided on the power protection cabinet 1 and is installed in coordination with the flow hole 40;

[0044] The blocking unit and the linkage unit are both located in the power protection cabinet 1, the blocking unit is located in the space enclosed by the power protection cabinet 1 and the L-shaped partition 27, and the linkage unit is respectively connected to the L-shaped partition 27 and the blocking unit.

[0045] Through the provided circulation hole 40, the heat generated in the power protection cabinet 1 can be discharged to the outside through the connecting slot 17 and the circulation hole 40, and finally discharged to the outside of the power protection cabinet 1 through the air outlet 8, thereby reducing the contact area between the ventilation part and the equipment, avoiding a large amount of dust falling on the electronic equipment, thereby affecting the service life, and through the provided sealing unit, wherein the sealing unit can be connected to the smoke probe 20, when a fire occurs in the power protection cabinet 1, the sealing unit can be driven to start through the smoke probe 20, and the circulation hole 40 can be blocked, so that the power protection cabinet 1 is in a closed space. At the same time, when the sealing unit is started, the linkage unit can be put into operation, so that the carbon dioxide in the containing cylinder B11 can be released, which is beneficial to improve the effect and efficiency of fire extinguishing and avoid further expansion of the accident.

[0046] In one embodiment of the present invention, the blocking unit comprises:

[0047] A push-pull member 24, wherein the push-pull member 24 is connected to the inner wall of the electric power protection cabinet 1, and the push-pull member 24 is also electrically connected to the smoke sensor 20;

[0048] a blocking plate 25 , wherein the blocking plate 25 is connected to the output end of the push-pull member 24 ; and a tapered rod 26 , wherein the tapered rod 26 is evenly distributed on the blocking plate 25 and is detachably connected to the flow hole 40 .

[0049] By setting up a push-pull member 24, which can be in the form of an electric push cylinder and connected to a power source through an independent circuit, the push-pull member 24 can push the blocking plate 25 to move in the direction of the L-shaped partition 27 after being energized, and make the conical rod 26 enter the flow hole 40, wherein a spherical body can be provided at the top end of the conical rod 26, thereby improving the sealing performance between the conical rod 26 and the inner wall of the smoke probe 20.

[0050] In one embodiment of the present invention, see Figure 4-6 , the linkage unit comprises:

[0051] A square frame 28 connected to the blocking plate 25;

[0052] A lifting plate 31, the lifting plate 31 is clamped in the square frame 28 through a limiting groove 30, and is connected to the inner top wall of the square frame 28 through a first spring 29, and the limiting groove 30 is opened on the square frame 28;

[0053] A connecting rod 32, one end of which is connected to the lifting plate 31, and the other end of which is connected to the bottom end of the square frame 28 and is slidably connected to the L-shaped partition plate 27;

[0054] a second sensor 39 , which is located on the control assembly and is installed in cooperation with the connecting rod 32 ; and an opening and closing member 21 , which is located on the air inlet pipe 9 and is also electrically connected to the second sensor 39 .

[0055] When the blocking plate 25 moves, the square frame 28 can be driven to move synchronously, wherein the bottom end of the square frame 28 can be slidably connected with the L-shaped partition 27 by clamping, or there can be a certain gap, which is not specifically limited here. When the square frame 28 moves, it can drive the connecting rod 32 to slide on the L-shaped partition 27, and through the first spring 29 provided, wherein the first spring 29 is always in a compressed state, a thrust can be exerted on the lifting plate 31. When the square frame 28 moves to the top of the control cylinder 23, since the top end of the control cylinder 23 is connected to the L-shaped partition 27, under the thrust of the first spring 29, the lifting plate 31 can slide downward in the square frame 28 through the limiting groove 30, and drive the connecting rod 32 to move downward synchronously. When the connecting rod 32 extends into the control cylinder 23, a pressure can be exerted on the control ball 36, so that the control ball 36 is pressed tightly against the second sensor 39. At this time, through the control of the second sensor 39 The opening and closing member 21 can be in the form of a solenoid valve, which can disconnect the air inlet pipe 9 and the delivery pipe 22 and the air inlet pipe 10 and the delivery pipe 22, thereby cutting off the high-pressure wind and putting the carbon dioxide gas into operation to achieve the purpose of rapid fire extinguishing. When a fire occurs, the temperature in the power protection cabinet 1 rises rapidly, and the control ball 36 is pressed against the first sensor 37 to cut off the circuit. At the same time, under the thrust of the connecting rod 32, the control ball 36 contacts the second sensor 39, thereby stopping the fan and putting the carbon dioxide gas into the fire extinguishing operation. At the same time, the sealing unit works in conjunction with the fan to improve the fire extinguishing effect. When the temperature rises, the fan will only increase its rotation speed and improve the heat dissipation effect, without putting the accommodating tube B11 and the sealing unit into operation, thereby ensuring the normal use of the equipment in the power protection cabinet 1 and improving the safety performance of the device.

[0056] In one embodiment of the present invention, see Figure 5 and Figure 7 , further comprising: a roller 33, the roller 33 being rollingly connected to the bottom end of the connecting rod 32; and a guide groove 41, the guide groove 41 being opened on the L-shaped partition 27 and connected to the roller 33.

[0057] By cooperating with the guide groove 41, when the blocking plate 25 drives the square frame 28 to move horizontally, the friction force of the connecting rod 32 during movement can be reduced, thereby improving the safety performance of the equipment. A push-pull plate is also provided on the lifting plate 31, so that after the equipment returns to normal, when the lifting plate 31 is pulled, the connecting rod 32 moves upward and separates from the control ball 36, thereby restoring the equipment to its original state.

[0058] In summary, during the use of the equipment, the power protection cabinet 1 is provided, wherein a steel plate is provided at the bottom of the power protection cabinet 1 to facilitate the connection of the power protection cabinet 1 with the external structure, and a single-opening door 2 is provided on the side wall of the power protection cabinet 1. When the single-opening door 2 is in a closed state, it is connected to the power protection cabinet 1. Sealed connection, a display 3 is also provided on the single door 2, which can be used to monitor and control the electronic equipment in the power protection cabinet 1. A cover plate 4 is provided on the top of the power protection cabinet 1 to prevent the power protection cabinet 1 from being exposed to wind and sun when the power protection cabinet 1 is installed outdoors. During the operation of the equipment in the power protection cabinet 1, the fan unit is started to allow the external natural wind to enter the air inlet pipe 9 after being pressurized, and to be transported to a plurality of delivery pipes 22 through the air inlet pipe 9. The plurality of delivery pipes 22 are respectively connected to the air holes 16 on the plurality of square mounting plates 14, wherein the square mounting plate 14 can be in the form of a square plate, and a mounting hole is opened on the top, so that the electrical equipment can be installed on the square mounting plate 14. At this time, the bottom of the electrical equipment is connected to the air hole 16. When high-pressure air is passed into the air hole 16, the high-pressure air can act directly on the electrical equipment, so that the specific electronic equipment can be fully cooled, the heat dissipation effect is improved, the service life of the equipment is extended, and the probability of fire is reduced as much as possible, providing convenience for the staff.
