DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] As Figures 1-4 shown, the present utility model provides a shielding room structure with high sealing performance, including an outer frame 101. A movable door 102 is arranged on the front side of the outer frame 101. A sealing strip 104 is arranged between the movable door 102 and the outer frame 101. A ventilator 105 is screwed to the upper surface of the outer frame 101;

[0025] A pressure regulating assembly 200 is arranged at the bottom outside of the outer frame 101 close to it. The pressure regulating assembly 200 includes a control box 201, a pressure gauge 202, an air compressor 203 and a vacuum pump 204. The control box 201 and the pressure gauge 202 are screwed to the outside of the outer frame 101. Pipes are arranged between the air compressor 203 and the vacuum pump 204 and the outer frame 101.

[0026] In addition, the air compressor 203 and the vacuum pump 204 are arranged outside the shield room, which can reduce the influence of noise and vibration on the environment inside the shield room, and the pressure gauge 202 is arranged outside for easy reading.

[0027] It is convenient for maintenance and heat dissipation because the bottom position is beneficial to the stability of the equipment and the contact with the ground.

[0028] Furthermore, in this embodiment, a shielding layer 107 is arranged inside the outer frame 101, a sealing layer 106 is arranged between the shielding layer 107 and the outer frame 101, and sealant 108 is filled between the shielding layer 107, the sealing layer 106 and the outer frame 101 to improve the sealing performance through the sealant 108.

[0029] In this embodiment, both the outer frame 101 and the movable door 102 are made of aluminum alloy, and protection is provided through the material of the outer frame 101. Conductive coatings are applied to the outer surfaces of the outer frame 101 and the movable door 102. The sealing layer 106 is made of one of polytetrafluoroethylene or silicone, and the shielding layer 107 is made of one of copper, aluminum or stainless steel.

[0030] In this embodiment, a movable hinge 103 is arranged at the upper end of the movable door 102 and the outer frame 101. The movable hinge 103 is respectively movably connected to the movable door 102 and the outer frame 101. It is convenient to open and close the movable door 102 through the movable hinge 103. A push rod is screwed to the upper inner end of the movable door 102, and the rear end of the push rod is screwed to the outer frame 101. The opening and closing of the movable door 102 are controlled through the push rod, and the push rod is controlled by a control box 201 arranged outside the outer frame 101. Sealing strips 104 are embedded on the outer sides of the movable door 102 to seal the connecting side between the movable door 102 and the outer frame 101 and improve the sealing performance.

[0031] In this embodiment, a single-chip microcomputer 2011 and a wireless connector 300 are arranged inside the control box 201. The input end of the single-chip microcomputer 2011 is communicatively connected to the output end of the pressure gauge 202, and the output end of the single-chip microcomputer 2011 is communicatively connected to the vacuum pump 204, the air compressor 203 and the ventilator 105. The wireless connector 300 is wirelessly communicatively connected to a wireless remote controller 400. The single-chip microcomputer 2011 receives data signals from the pressure gauge 202, controls the use of the vacuum pump 204, the air compressor 203 and the ventilator 105 through the single-chip microcomputer 2011, and enables the wireless remote controller 400 to remotely send control signals to the single-chip microcomputer 2011 through the wireless connector 300.

[0032] In this embodiment, the detection end of the pressure gauge 202 penetrates through one side of the outer frame 101 and is communicated with the inside of the outer frame 101, so as to realize the pressure detection of the inside of the shielding room by the pressure gauge 202. The air compressor 203 and the vacuum pump 204 are communicated with the outer frame 101 through pipelines. A pressure regulating valve is arranged between the pipelines and the air compressor 203 and the vacuum pump 204. By controlling the pressure regulating valve, the pressurization and decompression operations of the air compressor 203 and the vacuum pump 204 can be controlled, and the amount of gas entering or discharging can be controlled more precisely, so as to realize the fine adjustment of the pressure. Sealing rubber rings 108 are arranged at the joints of the pressure gauge 202, the air compressor 203 and the vacuum pump 204 with the outer frame 101, and the sealing performance is improved by the sealing rubber rings 108.

[0033] In this embodiment, an air lock is arranged between the ventilator 105 and the outer frame 101. The air lock is arranged at the output end of the ventilator 105, and the input end of the air lock is communicatively connected with the single-chip microcomputer 2011, and the enabling of the air lock is controlled by the single-chip microcomputer 2011.

[0034] In addition, by arranging the air lock, it is prevented that the external air flows backward into the shielding room through the ventilator 105. It is ensured that when the ventilator 105 is running, the indoor air is pumped out, and the external air will not flow backward into the room through the output end of the ventilator 105. The air lock plays the role of a buffer zone. Only after the inner door is closed can the outer door be opened.

[0035] Specifically, when using the shielding room, in order to improve the sealing performance of the shielding room, a sealing strip 104 is arranged between the gap between the shielding room and the movable door 102 for sealing. Ventilation is carried out by the ventilator 105, and the pressure inside the shielding room is detected in real time by the pressure gauge 202. A pressure threshold is preset in the single-chip microcomputer 2011. The air compressor 203 and the vacuum pump 204 are at the outer bottom. When the real-time pressure value is higher or lower than the pressure threshold, the single-chip microcomputer 2011 controls the air compressor 203 or the vacuum pump 204 to perform pressurization or decompression operations to ensure that the pressure inside the shielding room remains at a stable value;

[0036] Pressurization means that the air compressor 203 transports compressed air into the shielding room through a pipeline, and a pressure regulating valve is installed on the pipeline to control the air flow rate entering the shielding room, so as to adjust the indoor pressure. Decompression means that the vacuum pump 204 extracts air from the shielding room through another pipeline to reduce the indoor pressure. When the pressure reaches the threshold value, the vacuum pump 204 or the air compressor 203 stops. The opening degree of the regulating valve is adjusted by receiving the signal of the single-chip microcomputer 2011, or manually adjusted by wireless remote control, and the operator adjusts according to the reading of the pressure gauge 202.

[0037] It should be noted that the control method of this application document is automatically controlled by the single-chip microcomputer 2011. The control circuit of the single-chip microcomputer 2011 can be realized by simple programming of those skilled in the art, which belongs to the common general knowledge in this field. This application will not explain the control method and circuit connection in detail.

[0038] The outer frame 101, movable door 102, movable hinge 103, sealing strip 104, ventilator 105, sealing layer 106, shielding layer 107, sealant 108, control box 201, single-chip microcomputer 2011, pressure gauge 202, air compressor 203, vacuum pump 204, wireless connector 300, wireless remote control 400 and other components of the present utility model are all common standard components or components known to those skilled in the art.
