[0002] With the rapid development of information technology, government departments, public institutions and medium and large enterprises have built data centers and placed their own servers, switches and other equipment in the cabinets of the data center. When problems such as equipment short circuit, excessive dust, cable overload, etc. occur in the cabinet, it is easy to cause the equipment in the server to catch fire. Therefore, it is necessary to install automatic fire extinguishing devices in the cabinets.

[0003] For example, the public document with application number 201922203792.3 discloses an automatic fire extinguishing server cabinet. The utility model adopts an automatic alarm design structure. When the equipment in the cabinet catches fire, the temperature above the fire equipment rises, causing the fire detection tube above the fire equipment to soften and burst, the pressure in the fire detection tube drops, the container valve opens, and the fire-fighting gas in the fire-extinguishing agent cylinder enters the fire detection tube through the container valve and is ejected from the bursting point of the fire detection tube to extinguish the fire. At the same time, the fire alarm is activated to prompt the user that the fire extinguishing device is activated, and the fire extinguishing confirmation and repair of the fire extinguishing system are required, and the fire extinguishing agent cylinder is refilled with fire extinguishing agent. However, the automatic fire extinguishing device of the server cabinet adopts a large number of sensing equipment, the production cost is high, and the secondary use and repair cost is also high. In addition, the electrical sensing equipment is prone to damage and failure under high temperature and high pressure, or when it is left stationary for a long time, and it is not stable enough to use.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an automatic fire extinguishing device for a server cabinet is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide an automatic fire extinguishing device for a server cabinet to solve the problems raised in the above background technology.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 3 As shown, an automatic fire extinguishing device for a server cabinet comprises a containing box 1, the bottom of which is arranged as a complete through-hole, a T-plate 2 is rotatably arranged at the middle part of the lower part of the left and right sides of the outer surface of the containing box 1 through a rotating shaft seat, two sealing plates 3 are fixedly installed at the opposite ends of the T-plate 2, and the sealing plates 3 can seal the bottom of the containing box 1 after being horizontally butted, a connecting plate 4 is fixedly arranged at the front and rear sides of the opposite ends of the sealing plates 3, a tension spring 5 is rotatably arranged above the surface of the connecting plate 4 through a rotating shaft seat, the upper end of the tension spring 5 is rotatably connected to the left and right sides of the outer surface of the containing box 1 through the rotating shaft seat, opposite hooks 6 are fixedly installed below the surface of the sealing plate 3, and connecting ropes 7 are arranged on the opposite sides of the hooks 6 on both sides, and the T-plate 2 is rotatably connected with the rotating shaft seat of the receiving box 1 through the upper end vertical plate, and the connecting rope 7 is set on the hooks of the hooks 6 on both sides by using the knots at both ends. A buzzer 8 is fixedly installed on the front side of the outer surface of the receiving box 1, and a start button 9 is fixedly installed on the left and right sides of the outer surface of the receiving box 1 above the T-shaped plate 2. A cover feed port 10 is fixedly installed in the middle above the outer surface of the receiving box 1, and the cover feed port 10 is composed of a feed pipe and a screw cover. The inner surface of the receiving box 1 is set with inclined surfaces 11 on both sides, and the upper end of the inclined surface 11 is inclined from the middle of the receiving box 1 to the left and right sides of the receiving box 1. Mounting ears 12 are fixedly installed on the left and right sides above the outer surface of the receiving box 1, and the mounting ears 12 are set in an "L" shape and connected to the cabinet by bolts.

[0022] Furthermore, the hook 6 is fixed to the sealing plate 3 , and the connecting rope 7 connects the sealing plates 3 at both ends by means of the hook 6 , so that the sealing plates 3 are oppositely leveled and the containing box 1 is closed.

[0023] Furthermore, the tension spring 5 is connected to the sealing plate 3 by the connecting plate 4. When the sealing plate 3 is horizontally relatively closed, the tension spring 5 is in a stretched state, providing a tension for the sealing plate 3 to rotate toward both sides all the time.

[0024] Furthermore, the connecting rope 7 is melted, thereby losing the limiting tension on the sealing plates 3 on both sides. The tension spring 5 will then pull the sealing plates 3 to rotate through the T-plate 2, thereby opening the receiving box 1 to release the fire extinguishing agent.

[0025] Furthermore, the start button 9 is located above the T-plate 2, and the start button 9 controls the start of the buzzer 8. One end of the T-plate 2 can rotate upward under the tension of the tension spring 5, and pressing the start button 9 activates the buzzer 8 for warning.

[0026] Furthermore, the inclined surface 11 is inclined toward both sides, so that the fire extinguishing agent inside the vertically installed container box 1 can be smoothly cast out, avoiding the situation where the inner wall arranged at a right angle receives the fire extinguishing agent.

[0027] Working principle: When using the automatic fire extinguishing device of the server cabinet, first, use the connecting rope 7 to connect the hooks 6 at both ends, so that the sealing plate 3 is closed and blocks the bottom end of the receiving box 1, and then add the fire extinguishing agent to the inside of the receiving box 1 through the sealing cover feed port 10, and then use the bolts and mounting ears 12 to install the receiving box 1 at the top or left and right sides inside the cabinet. The fire extinguishing agents on both sides can be fully accumulated on one side of the sealing plate 3 by using the inclined surface 11. When a short circuit occurs inside the cabinet and a fire occurs, the flame will jump and the connecting rope 7 will melt. Without the force of the connecting rope 7 to pull the hook 6, the tension spring 5 will pull the sealing plate 3 at the T-plate 2 position through the connecting plate 4, and rotate to both sides to open the bottom of the receiving box 1, so that the internal fire extinguishing powder is sprinkled downward, completing the automatic fire extinguishing. At the same time, one end of the T-plate 2 rotates and moves upward, and under the traction of the tension spring 5, it will press the start button 9 to make the buzzer 8 sound, and provide a synchronous fire warning to the manual staff. This is the working principle of the automatic fire extinguishing device of the server cabinet.
