The door leaf is composed of a rhenium plate 2, a silver nanoparticle plate 3, a tungsten alloy plate 4, and an osmium alloy plate 5 from front to back. Rhenium is a material with excellent shielding performance. Rhenium has high density and high atomic number, which makes it perform well in X-ray radiation shielding. The rhenium plate 2 made of rhenium can provide a highly efficient radiation shielding effect. The shielding ability of rhenium mainly comes from its high density and atomic number. Due to its high density, rhenium can effectively absorb the energy of X-rays and reduce their penetration ability. At the same time, the high atomic number of rhenium causes it to interact with X-rays, further increasing the shielding effect.

[0035] Silver nanoparticle plate 3 is a material prepared using silver nanoparticles, which has excellent X-ray shielding performance. Silver nanoparticles have excellent X-ray scattering and absorption properties, which can effectively reduce the penetration ability of X-rays and provide efficient radiation shielding.

[0036] Tungsten alloys are a very dense material, and therefore perform excellently in X-ray and gamma-ray shielding.

[0037] Osmium is a platinum group metal; therefore, the osmium alloy plate 5 made of osmium has high density and radiation shielding performance. The inner bottom wall and inner top wall of the door frame 1 are rotatably fitted with a pivot 6. The door leaf is equipped with a fireproof mechanism. The pivot 6 is equipped with an automatic opening and closing mechanism at the upper end of the door frame 1. A manual opening and closing conversion mechanism is provided above the automatic opening and closing mechanism. A controller 7 for controlling the fireproof mechanism, the automatic opening and closing mechanism, and the manual opening and closing conversion mechanism is fixedly installed on the upper surface of the door frame 1.

[0038] The fire prevention mechanism includes a compressed gas storage cylinder 8 and an airbag 81. In the event of a fire, the fire prevention mechanism separates the fire and non-fire areas.

[0039] The automatic opening and closing mechanism includes a worm gear 9 and a worm 91. The controller 7 controls the automatic opening and closing mechanism to automatically open and close the door.

[0040] The manual opening and closing switching mechanism includes a cylinder 10, which controls the automatic opening and closing mechanism to separate from the rotating shaft 6 through the controller 7, so that the door can switch from automatic to manual opening and closing.

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, fire-resistant expansion sealing strips 82 are fixedly connected to the outer surfaces of the rhenium plate 2, silver nanoparticle plate 3, tungsten alloy plate 4, and osmium alloy plate 5, which are attached to the inner wall of the door frame 1. The fire-resistant expansion sealing strips 82 can effectively prevent flames from escaping and block the spread of fire. A GPS positioning module 83 and a wireless transmission module 84 are fixedly installed on the upper surface of the door frame 1, respectively. A temperature sensor 85 and a smoke sensor 86 are fixedly installed on the front of the rhenium plate 2, respectively. The controller 7 is connected to the ship's fire alarm system through the wireless transmission module 84. When a fire occurs inside the ship's medical room... At the same time, temperature sensor 85 and smoke sensor 86 are set to monitor the fire situation in real time and send a fire signal to controller 7. After processing by controller 7, the signal and location information of GPS positioning module 83 are sent to the ship's fire alarm system, thereby reminding the crew to take timely measures to prevent the fire from spreading and causing greater harm. The fire protection mechanism also includes mounting cavities 87 opened inside rhenium plate 2, silver nanoparticle plate 3, tungsten alloy plate 4 and osmium alloy plate 5. Fireproof door core plate 88 is fixedly installed on the inner wall of mounting cavity 87. Fireproof door core plate 88 is usually made of Constructed from fireproof rock wool, high-temperature resistant materials, or other flame-retardant materials, it can resist flame attack for a certain period of time and also has a certain sound insulation effect. The compressed gas storage cylinder 8 is filled with pre-compressed dry powder extinguishing agent. The compressed gas storage cylinder 8 is fixedly installed in the inner wall space of the installation cavity 87 near the left side of the fireproof door core plate 88. The outlet of the compressed gas storage cylinder 8 is fixedly connected to the outlet pipe 810 with a normally closed solenoid valve 89. One end of the outlet pipe 810 is fixedly connected to the inlet of the airbag 81. The airbag 81 is placed in the installation cavity 87 on the fireproof door core plate 88. Inside the airbag 81, the airbag 81 contacts the inner wall of the fireproof door core panel 88. When the controller 7 receives a fire signal, the controller 7 controls the normally closed solenoid valve 89 to open the valve, releasing the pre-compressed dry powder extinguishing agent in the compressed gas storage bottle 8 into the airbag 81 through the gas outlet pipe 810, causing it to inflate rapidly. At this time, the compressed gas and dry powder extinguishing agent in the airbag 81 are under high pressure. Once the flames rupture the airbag 81, the high-pressure compressed gas and dry powder extinguishing agent will be rapidly sprayed out, forming a mist or powder extinguishing agent to extinguish the flames and prevent the fire from continuing to spread.

[0042] The above scheme is adopted: the controller 7 is connected to the ship's fire alarm system through the wireless transmission module 84. When a fire occurs inside the ship's medical room, the temperature sensor 85 and the smoke sensor 86 are set up to monitor the fire situation in real time and send a fire signal to the controller 7. After processing, the controller 7 sends the signal and the location information of the GPS positioning module 83 to the ship's fire alarm system, thereby reminding the crew to take timely measures to prevent the fire from spreading and causing greater harm.

[0043] like Figure 1 , Figure 2, Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the automatic opening and closing mechanism also includes a first touch switch 92 installed on the inner left wall of the door frame 1. The rotating shaft 6 is fixedly sleeved at the through hole on the left side surface of the door leaf on the outer surface of the inner door frame 1. A second touch switch 93 is fixedly installed on the back of the osmium alloy plate 5. The trigger end of the second touch switch 93 passes through the fireproof expansion sealing strip 82 and extends to the back of the fireproof expansion sealing strip 82. Handles 94 are fixedly installed on both the front and back of the osmium alloy plate 5. A face recognition access control 95 is fixedly installed on the back of the door frame 1. A power input shaft 96 is inserted into one end of the rotating shaft 6 located above the door frame 1. A mounting bracket 98 is rotatably sleeved on the outer surface of the power input shaft 96. A worm gear 9 is fixedly sleeved on one end of the power input shaft 96 located inside the mounting bracket 98. Symmetrically distributed bearing seats 99 are fixedly installed on the inner bottom wall of the mounting bracket 98. The worm 91 is rotatably sleeved on the inner wall of the two bearing seats 99. The outer surface of the worm 91 meshes with the inner wall of the tooth groove of the worm wheel 9. The mounting bracket 98 is fixedly mounted on the inner bottom wall of the back of one of the bearing seats 99. The output shaft of the power input motor 97 is fixedly connected to one end of the worm 91 through a coupling. The front of the door frame 1 is provided with a foot groove 910 with an inclined inner bottom wall. The inner bottom wall of the foot groove 910 is provided with mounting grooves 911 arranged in a linear array. The inner bottom wall of the mounting groove 911 is fixedly mounted with a spring 912. One end of the spring 912 is fixedly mounted with a foot pedal 914. The inner bottom wall of the foot groove 910 located at the center of the four mounting grooves 911 is fixedly mounted with a third touch switch 913. The trigger end of the third touch switch 913 is in contact with the lower surface of the foot pedal 914.

[0044] The above solution is adopted: Controller 7 controls the automatic opening and closing mechanism to achieve automatic opening or emergency closing, so as to realize intelligent door control and more rapid and accurate response to fire events;

[0045] When it is necessary to control the door to open automatically, the power input motor 97 reverses, and the power input motor 97 drives the worm 91 to mesh with the worm wheel 9, which drives the power input shaft 96 connected to the inner wall of the worm wheel 9 to rotate, which drives the rotating shaft 6 connected to the power input shaft 96 to rotate, and then drives the door connected to the surface of the rotating shaft 6 to rotate clockwise around the axis of the rotating shaft 6. When the rhenium plate 2 contacts the first touch switch 92, it controls the power input motor 97 to stop working. At this time, the door is in the automatic opening state.

[0046] When it is necessary to control the emergency closing of the door, the power input motor 97 rotates forward, driving the door connected to the surface of the rotating shaft 6 to rotate counterclockwise around the axis of the rotating shaft 6. When the door frame 1 contacts the second touch switch 93, the power input motor 97 is controlled to stop working. At this time, the door is in the emergency closing state.

[0047] In addition, by setting a fireproof door core plate 88 inside the installation cavity 87, it can resist the attack of flames for a certain period of time. At the same time, it also has a certain sound insulation effect, creating a comfortable environment for the crew and reducing the harm of noise to the human body.

[0048] In normal use, when it is necessary to enter the ship's medical room, the face recognition access control 95 scans the face, which controls the automatic opening and closing mechanism to automatically open the door. When it is necessary to leave the ship's medical room, the foot pedal 914 is pressed, which makes the pedal 914 contact the third trigger switch, which automatically opens the door from inside the ship's medical room.

[0049] like Figure 4 and Figure 6 As shown, the manual opening and closing conversion mechanism also includes a flange 101. One end of the piston rod of the cylinder 10 is fixedly sleeved with the inner wall of the flange 101. The flange 101 is fixedly connected to the mounting bracket 98 by bolts.

[0050] Using the above solution: When it is necessary to switch the door from automatic to manual opening and closing, the controller 7 controls the cylinder 10 to retract, which drives the mounting bracket 98 to move upward along the height direction of the cylinder 10, causing the power input shaft 96 to separate from the rotating shaft 6. At this time, the door can be manually opened or closed simply by pulling the handle 94 or closing the handle 94.

[0051] Working principle and usage process of this invention:

[0052] Step 1: The door panel, composed of rhenium plate 2, silver nanoparticle plate 3, tungsten alloy plate 4 and osmium alloy plate 5, uses multiple shielding methods to achieve a highly efficient shielding effect against X-ray radiation. Compared with existing door panels made of lead plates or concrete, it provides more comprehensive and effective X-ray radiation shielding, thereby reducing the radiation impact on the human body and equipment.

[0053] Step two: The controller 7 is connected to the ship's fire alarm system via the wireless transmission module 84. When a fire occurs inside the ship's medical room, the temperature sensor 85 and smoke sensor 86 are set up to monitor the fire situation in real time and send a fire signal to the controller 7. The controller 7 then processes the signal and sends the location information along with the GPS positioning module 83 to the ship's fire alarm system, thereby alerting the crew to take timely measures to prevent the fire from spreading and causing greater harm. The specific measures are as follows:

[0054] When the controller 7 receives a fire signal, the controller 7 controls the normally closed solenoid valve 89 to open the valve, releasing the pre-compressed dry powder extinguishing agent in the compressed gas storage cylinder 8 into the airbag 81 through the gas outlet pipe 810, so that it is quickly inflated. At this time, the compressed gas and dry powder extinguishing agent in the airbag 81 are under high pressure. Once the flames rupture the airbag 81, the high-pressure compressed gas and dry powder extinguishing agent will be quickly sprayed out, forming a mist or powder extinguishing agent to extinguish the flames and prevent the fire from continuing to spread.

[0055] Meanwhile, the controller 7 controls the automatic opening and closing mechanism to achieve automatic opening or emergency closing, so as to realize intelligent door control and more rapid and accurate response to fire events.

[0056] When it is necessary to control the door to open automatically, the power input motor 97 reverses, and the power input motor 97 drives the worm 91 to mesh with the worm wheel 9, which drives the power input shaft 96 connected to the inner wall of the worm wheel 9 to rotate, which drives the rotating shaft 6 connected to the power input shaft 96 to rotate, and then drives the door connected to the surface of the rotating shaft 6 to rotate clockwise around the axis of the rotating shaft 6. When the rhenium plate 2 contacts the first touch switch 92, it controls the power input motor 97 to stop working. At this time, the door is in the automatic opening state.

[0057] When it is necessary to control the emergency closing of the door, the power input motor 97 rotates forward, driving the door connected to the surface of the rotating shaft 6 to rotate counterclockwise around the axis of the rotating shaft 6. When the door frame 1 contacts the second touch switch 93, the power input motor 97 is controlled to stop working. At this time, the door is in the emergency closing state.

[0058] In addition, by setting a fireproof door core plate 88 inside the installation cavity 87, it can resist the attack of flames for a certain period of time. At the same time, it also has a certain sound insulation effect, creating a comfortable environment for the crew and reducing the harm of noise to the human body.

[0059] Step 3: When it is necessary to switch the door from automatic to manual opening and closing, the controller 7 controls the cylinder 10 to retract, which drives the mounting bracket 98 to move upward along the height direction of the cylinder 10, causing the power input shaft 96 to separate from the rotating shaft 6. At this time, the door can be manually opened or closed simply by pulling the handle 94 or closing the handle 94.

[0060] Step four: During normal use, when it is necessary to enter the ship's medical room, the face recognition access control 95 scans the face, which controls the automatic opening and closing mechanism to automatically open the door. When it is necessary to leave the ship's medical room, the foot pedal 914 is pressed to make the pedal 914 contact the third trigger switch, which will automatically open the door from inside the ship's medical room.
