The effective use of these equipments can provide valuable time for personnel evacuation and rescue in case of emergency and reduce the losses caused by disasters.

[0003] According to the publicly disclosed patent CN213573733U, an automatically controllable fireproof biological shielding door includes two door leaves.

And on the outer sides of the two door leaves, fireproof layers are symmetrically installed. At the middle seam between the two door leaves, a fireproof expansion sealing strip is installed. In the process of implementing the utility model, although the automatic control of the shielding door is realized, and it has a ray shielding function and a 3.0-hour fireproof function, which can meet the high security requirements in the high-security field, its sealing performance is poor, and it cannot effectively prevent thick smoke from spreading into the room and endangering personal safety, greatly reducing the survival rate. Therefore, a new technical solution needs to be designed to solve this problem. Content of the Utility Model

Through the combination of structures such as a smoke sensor, an electromagnetic valve, a controller, a water inlet pipe, a biological shielding door, a limiting frame and a rubber sealing frame, when a fire occurs, the biological shielding door is closed. When the smoke sensor detects a fire, the electromagnetic valve is automatically opened through the controller, so that water enters between the biological shielding door and the limiting frame through the water inlet pipe, and then the water is limited in cooperation with the rubber sealing frame, so as to seal between the biological shielding door and the limiting frame through water, thereby greatly improving the sealing effect when the biological shielding door is closed, and further effectively preventing thick smoke from spreading into the room and endangering personal safety.

[0012] 2. By combining structures such as exhaust holes, sealing plugs, and water level sensors, when the electromagnetic valve is opened to let water in, air pressure pushes up the sealing plug to discharge the air between the biological shielding door and the limit frame through the exhaust hole, thus facilitating the addition of water between the biological shielding door and the limit frame. When the water level between the biological shielding door and the limit frame reaches the position where it contacts the water level sensor in the exhaust hole, the electromagnetic valve is closed through the controller, thereby avoiding waste caused by a large amount of water being discharged from the water inlet pipe.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The present utility model will be further described below with reference to the drawings and embodiments:

[0021] Embodiment 1: An intelligent new type of fireproof biological shielding equipment, see Figures 1 to 6, including a door frame 1, with a limit frame 13 installed inside the door frame 1. One end of the limit frame 13 is on the same horizontal plane as one end of the door frame 1. Hinges 12 are installed on both the upper and lower sides of one end of the door frame 1. The door frame 1 is hinged with a biological shielding door 11 through two hinges 12. A rubber sealing frame 14 is installed at one end of the biological shielding door 11 close to the limit block. One side of the top of the door frame 1 is provided with a water inlet pipe 2. One end of the water inlet pipe 2 is communicated with a water source. The water inlet pipe 2 is the same as the inner side of the door frame 1 between the limit frame 13 and the biological shielding door 11. An electromagnetic valve 21 is installed on the outer side of the water inlet pipe 2. Above one end of the door frame 1 far from the hinge 12, a smoke sensor 3 and a controller 31 are installed. The output end of the smoke sensor 3 is connected to the input end of the controller 31 through a wire. The output end of the controller 31 is connected to the input end of the electromagnetic valve 21 through a wire. During operation, when a fire occurs, the biological shielding door 11 is closed. When the smoke sensor 3 detects a fire, the electromagnetic valve 21 is automatically opened through the controller 31. Thus, water enters between the biological shielding door 11 and the limit frame 13 through the water inlet pipe 2. Then, in cooperation with the rubber sealing frame 14, the water is limited, and the space between the biological shielding door 11 and the limit frame 13 is sealed with water. Thus, the sealing effect when the biological shielding door 11 is closed is greatly improved, and further, the spread of thick smoke into the room to endanger personal safety can be effectively prevented.

[0022] Specifically, refer to Figure 5 , on one side of the top of the door frame 1 far from the water inlet pipe 2, an exhaust hole 5 is opened. A sealing plug is slidably inserted into the exhaust hole 5. A connecting plate 51 is installed at the top of the sealing plug. Limit mechanisms are arranged between both sides of the bottom of the connecting plate 51 and the door frame 1. A water level sensor 53 is installed at the bottom of the sealing plug. The output end of the water level sensor 53 is connected to the input end of the controller 31 through a wire. The output end of the controller 31 is connected to the input end of the electromagnetic valve 21 through a wire. When the electromagnetic valve 21 is opened for water inlet, air pressure pushes the sealing plug up to discharge the air between the biological shielding door 11 and the limit frame 13 through the exhaust hole 5. Thus, it is convenient to add water between the biological shielding door 11 and the limit frame 13. When the water level between the biological shielding door 11 and the limit frame 13 reaches the position where it contacts the water level sensor 53 in the exhaust hole 5, the electromagnetic valve 21 is closed through the controller 31. Thus, a large amount of water discharged from the water inlet pipe 2 is avoided from being wasted.

[0023] Furthermore, refer to Figure 5 , the limit mechanism is a limit telescopic rod 52. The maximum stretching length of the limit telescopic rod 52 is greater than the length of the sealing plug. The limit telescopic rod 52 can guide the up and down movement of the sealing plug, and thus ensure that the sealing plug can be accurately inserted into the exhaust hole 5 when moving up and down.

[0024] It should be noted that refer to Figure 1, on one side of one end of the door frame 1 close to the smoke sensor 3, an automatic door opener 4 is installed. The driving end of the automatic door opener 4 is connected to the biological shielding door 11, and the biological shielding door 11 can be automatically opened and closed through the automatic door opener 4.

[0025] It should be noted that, referring to Figure 6 , the thickness of the rubber sealing frame 14 is greater than the distance between the limiting frame 13 and the biological shielding door 11. The rubber sealing frame 14 is elastic and heat-resistant, and is used to improve the sealing effect of the connection between the biological shielding door 11 and the limiting frame 13, and further improve the sealing effect when a fire occurs in the biological shielding door 11.

[0026] In addition, the components designed in the present utility model are all common standard components or components known to those skilled in the art. Their structures and principles can all be known by those skilled in the art through technical manuals or through conventional experimental methods. Those skilled in the art can fully implement them without further elaboration. The content protected by the present utility model does not involve improvements to the internal structure and method either.

[0027] The embodiments disclosed in the present utility model are preferred embodiments, but not limited thereto. Those of ordinary skill in the art can easily understand the spirit of the present utility model based on the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present utility model, they are all within the protection scope of the present utility model.
