[0013] Preferably, it further comprises a guiding mechanism for guiding the rack plate, wherein the guiding mechanism comprises a round rod rotatably mounted on the inner wall of the cabinet, a guide wheel is fixed on the round rod, and the guide wheel abuts against the rack plate.

[0014] Preferably, the moving mechanism includes a driving box connected to the air outlet pipe, a short tube rotatably arranged through the bottom of the driving box, a rectangular piston cylinder is fixedly connected to the bottom of the short tube, a rectangular piston is slidably connected in the rectangular piston cylinder, a connecting tube connected to the rectangular piston is penetrated through the rectangular piston, a hollow reciprocating screw is installed at the bottom of the connecting tube, a support block is fixed to the inner wall of the cabinet, the reciprocating screw penetrates the support block and is connected with the support block, a guide pipe is rotatably connected to the bottom of the reciprocating screw, a guide plate is fixed on the guide pipe, and the guide plate slides against the cabinet.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. After the air is ejected through the curved pipe, the air flow rate at the bottom of the capillary tube is fast, and the air flow rate at the upper end is slow, resulting in a small pressure at the bottom of the capillary tube and a large pressure at the upper end of the capillary tube. Therefore, a pressure difference is generated between the upper and lower ends of the capillary tube. Therefore, the air will flow through the capillary tube into the curved pipe. Since the capillary tube is set close to the annular net, the dust filtered on the annular net can be sucked away, thereby cleaning the annular net and avoiding blockage of the annular net.

[0018] 2. After the pull rope is melted, the connecting block moves under the action of the first spring, thereby driving the two baffles to move relative to each other. Finally, the two baffles block the bottom of the fan, so that the air in the cabinet cannot circulate, and the corresponding air will not enter the air through the air inlet pipe.

[0019] 3. After the pull rope is melted, the moving block moves downward under the action of the second spring and the telescopic rod, and the moving block drives the rack plate to move downward, and the rack plate drives the gear to rotate, and the gear rotation drives the shaft rod to rotate, and the shaft rod rotation drives the worm to rotate, and the worm rotation drives the worm wheel to rotate, and the worm wheel rotation drives the valve to rotate, so that the valve opens.

[0020] 4. The carbon dioxide in the carbon dioxide storage tank is ejected through the outlet pipe and vaporized into the drive box, and then enters the rectangular piston cylinder through the carbon dioxide. Finally, the carbon dioxide is ejected through the connecting pipe, the hollow reciprocating screw and the guide pipe. The carbon dioxide ejected from the guide pipe is sprayed onto the server equipment, which can cool the server equipment and isolate oxygen at the same time, so that the server equipment will not burn due to a short circuit.

[0021] 5. When air passes through the drive box, it passes through the spiral blades, thus driving the spiral blades to rotate. The rotation of the spiral blades drives the vertical rod and the connecting rod to rotate. The rotation of the connecting rod drives the short tube to rotate. The rotation of the short tube drives the rectangular piston cylinder and the rectangular piston to rotate, thereby realizing the rotation of the connecting tube and the reciprocating screw. The reciprocating screw rotates up and down on the support block. At this time, the rectangular piston moves up and down on the rectangular piston cylinder, so that the guide tube can move back and forth up and down, and carbon dioxide can be evenly sprayed onto the server equipment, which can be fully and effectively cooled and extinguished, thereby protecting the server equipment.

[0022] In summary, the present invention utilizes the heat generated by the short circuit of the server equipment to drive the valve to open, so that carbon dioxide can be evenly sprayed onto the server body, and the server body can be fully and effectively cooled and fire extinguished, thereby protecting the server equipment.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Reference Figure 1-Figure 8 A big data server with a protective device includes a cabinet 1, a mounting frame 2 is installed in the cabinet 1, and a server device 3 is installed on the mounting frame 2; wherein a switch door is installed on the cabinet 1, and the switch door is not shown in the figure.

[0034] A protection component capable of protecting the server equipment 3; the protection component includes a fan 7 installed at the upper end of a cabinet 1, and a mesh plate can be installed at the air outlet end of the fan 7 to prevent debris from falling into the fan 7 and causing damage to it; two baffles 14 symmetrically arranged and capable of being reset are slidably connected to the inner top of the cabinet 1, and two guide rods 16 are fixed to the inner wall of the cabinet 1, and connecting blocks 15 are fixed at both ends of the baffles 14, the guide rods 16 pass through the connecting blocks 15 and are slidably connected thereto, and a first spring 21 is fixed on the connecting block 15, and the other end of the first spring 21 is fixedly connected to the inner wall of the cabinet 1, and the first spring 21 is set on the outside of the guide rods 16, and the first spring 21 is in a compressed state at this time.

[0035] The two baffles 14 are reset to oppose each other to block the fan 7. Two carbon dioxide storage tanks 8 are installed on the inner top of the cabinet 1. The outlet pipes 24 of the carbon dioxide storage tanks 8 are provided with valves. A moving block 25 that can move up and down is provided in the cabinet 1. A telescopic rod 22 and a second spring 23 are fixedly connected to the inner top of the cabinet 1. The telescopic rod 22, the second spring 23 and the moving block 25 are fixedly connected. The second spring 23 is set on the outside of the telescopic rod 22. The moving block 25 can be moved downward by the second spring 23. Under the guidance of the telescopic rod 22, the stable movement of the moving block 25 is guaranteed.

[0036] The moving block 25 is fixedly connected to the baffle 14 through a pull rope 20. When the server equipment 3 is short-circuited and high-temperature smoke or flames flow upward, the smoke or flames burn it through the pull rope 20, so that the baffle 14 is reset, the fan 7 is blocked and the air circulation is reduced. A driving mechanism is installed in the cabinet 1. The moving block 25 moves downward to drive the driving mechanism to open the valve. The driving mechanism includes a rack plate 26 fixed to the bottom of the moving block 25. The inner wall of the cabinet 1 is rotatably connected to a shaft rod 29, on which a worm 28 is fixed, and a gear 27 is fixedly connected to the shaft rod 29. The gear 27 is meshed with the rack plate 26. A worm wheel 32 is installed on the valve, and the worm wheel 32 is meshed with the worm 28. In order to ensure the stable downward movement of the rack plate 26, a guide mechanism for guiding the rack plate 26 is also included. The guide mechanism includes a round rod 31 rotatably installed on the inner wall of the cabinet 1, and a guide wheel 30 is fixed on the round rod 31, and the guide wheel 30 is against the rack plate 26.

[0037] The carbon dioxide in the carbon dioxide storage tank 8 can be discharged, and a moving mechanism is installed in the cabinet 1. The moving mechanism moves up and down to evenly spray the carbon dioxide onto the server equipment 3, so as to cool down and extinguish the fire of the server equipment 3; the moving mechanism includes a driving box 10 connected to the exhaust pipe 24, and a short tube 34 is penetrated at the bottom of the driving box 10 and is rotatably arranged therewith. A cross bar 36 is fixedly connected to the driving box 10, and a vertical rod 37 is penetrated up and down by the cross bar 36 and is rotatably arranged therewith. A connecting rod 35 is fixed to the bottom of the vertical rod 37, and the connecting rod 35 is fixedly connected to the short tube 34, and a plurality of spiral leaves 38 are fixed on the vertical rod 37.

[0038] The bottom of the short tube 34 is fixedly connected to a connected rectangular piston cylinder 9, and a rectangular piston 39 is slidably connected inside the rectangular piston cylinder 9. A connecting pipe 40 connected to the rectangular piston 39 is penetrated by the rectangular piston 39, and a hollow reciprocating screw 33 is installed at the bottom of the connecting pipe 40. A support block 18 is fixed to the inner wall of the cabinet 1. The reciprocating screw 33 penetrates the support block 18 and is connected thereto. The bottom of the reciprocating screw 33 is rotatably connected to a guide pipe 17, and a guide plate 19 is fixed on the guide pipe 17. The guide plate 19 slides against the cabinet 1, wherein an L-shaped rod can be fixed on the inner wall of the cabinet 1, and the L-shaped rod penetrates the guide plate 19 and is slidably arranged, so that the stable movement of the guide plate 19 can be ensured.

[0039] In addition, the fan 7 works to exhaust the air in the cabinet 1, and it is necessary to supply air to the cabinet 1 to ensure the air circulation in the cabinet 1, so as to dissipate the heat of the server equipment 3. For this purpose, an air intake component is also included, through which the external air can enter the cabinet 1 to realize the air circulation in the cabinet 1. The air intake component includes a mounting plate 4 installed in the cabinet 1, and a circular cavity is provided in the middle of the mounting plate 4. An air intake pipe 6 is embedded and installed on the mounting plate 4, and one end of the air intake pipe 6 is connected to the circular cavity. The other end of the air inlet pipe 6 passes through the cabinet 1, and a diverter box 11 is rotatably connected to the air inlet pipe 6. A plurality of bent pipes 13 are fixed to the diverter box 11, and a thin tube 12 connected to the bent pipe 13 is fixed to the upper end thereof. An annular net 5 for blocking the upper end of the circular cavity is installed on the mounting plate 4, and the thin tube 12 is arranged close to the annular net 5 and does not abut against the annular net 5; wherein a circular plate is fixed to the inner wall of the annular net 5, and a supporting ring is fixed to the outside, so that the support and fixation of the annular net 5 are completed in this way.

[0040] When the present invention is used, the fan 7 works to exhaust the air in the cabinet 1, and the external air enters the diversion box 11 through the air inlet pipe 6. Finally, the air is ejected through the curved pipe 13 and sprayed into the circular cavity. Finally, the air is filtered by the annular net 5 and flows into the cabinet 1, so that the air in the cabinet 1 can be circulated, and the server equipment 3 can be cooled.

[0041] After the air is ejected through the curved pipe 13, the resistance of the air will drive the curved pipe 13 and the diverter box 11 to rotate with the air inlet pipe 6 as the axis. The rotation of the curved pipe 13 drives the capillary 12 to rotate. After the air is ejected through the curved pipe 13, the air flow rate at the bottom of the capillary 12 is fast, and the air flow rate at the upper end is slow, resulting in a small pressure at the bottom of the capillary 12 and a large pressure at the upper end of the capillary 12. Therefore, a pressure difference is generated between the upper and lower ends of the capillary 12, so the air will flow into the curved pipe 13 through the capillary 12 (Bernoulli principle). Since the capillary 12 is arranged close to the annular net 5, the dust filtered on the annular net 5 can be sucked away, so as to clean the annular net 5 and avoid the annular net 5 from being blocked.

[0042] A brush or cotton can be fixed on the inner wall of the circular cavity, and after the air containing dust is blown toward the brush or cotton, the dust adheres to the brush or cotton, thereby achieving the effect of absorbing dust;

[0043] If the server device 3 short-circuits to generate smoke or flames, the high-temperature smoke or flames or air heated by the flames will flow upwards due to the operation of the fan 7, and the hot air will heat the pull rope 20 to make it melt (the material of the pull rope 20 can be selected according to actual conditions); after the pull rope 20 melts, the connecting block 15 moves under the action of the first spring 21, and then drives the two baffles 14 to move relative to each other, and finally the two baffles 14 block the bottom of the fan 7, so that the air in the cabinet 1 cannot circulate, and the corresponding air will not enter the air through the air inlet pipe 6;

[0044] After the pull rope 20 is melted, under the action of the second spring 23 and the telescopic rod 22, the moving block 25 moves downward, the moving block 25 drives the rack plate 26 to move downward, the rack plate 26 drives the gear 27 to rotate, the gear 27 drives the shaft 29 to rotate, the shaft 29 drives the worm 28 to rotate, the worm 28 drives the worm wheel 32 to rotate, the worm wheel 32 drives the valve to rotate, so that the valve is opened;

[0045] The carbon dioxide in the carbon dioxide storage tank 8 is ejected through the outlet pipe 24 and vaporized into the drive box 10, and then enters the rectangular piston cylinder 9 through the carbon dioxide, and finally the carbon dioxide is ejected through the connecting pipe 40, the hollow reciprocating screw rod 33 and the guide pipe 17. The carbon dioxide ejected from the guide pipe 17 is sprayed onto the server device 3, which can cool the server device 3 and isolate oxygen at the same time, so that the server device 3 will not burn due to a short circuit;

[0046] When air passes through the drive box 10, it passes through the spiral blade 38, thereby driving the spiral blade 38 to rotate. The rotation of the spiral blade 38 drives the vertical rod 37 and the connecting rod 35 to rotate. The rotation of the connecting rod 35 drives the short tube 34 to rotate. The rotation of the short tube 34 drives the rectangular piston cylinder 9 and the rectangular piston 39 to rotate, thereby realizing the rotation of the connecting tube 40 and the reciprocating screw 33. The reciprocating screw 33 rotates and reciprocates up and down on the support block 18. At this time, the rectangular piston 39 reciprocates up and down on the rectangular piston cylinder 9, thereby realizing the reciprocating up and down movement of the guide tube 17, so that carbon dioxide can be evenly sprayed onto the server equipment 3, and it can be fully and effectively cooled and extinguished, thereby realizing the protection of the server equipment 3.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
