[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1

[0035] Reference Figures 1-5 , which is the first embodiment of the present invention, and this embodiment provides an object transfer device for the main control room of a nuclear power plant, including a protection module 100, which is installed on the wall of the main control room; a transmission module 200, which is arranged inside the protection module 100 and is used to load objects to be transferred; a ventilation module 300, which is connected to the protection module 100, and is used to maintain air circulation inside and outside the protection module 100 and maintain air pressure balance; a purification module 400, which is located at a position of the protection module 100 close to the outer side of the main control room, and is used to purify the air entering or leaving the protection module 100; an object box 500, which is placed in the transmission module 200, and is used to hold objects to be transferred, and the object transfer can be achieved by moving the object box 500.

[0036] In this embodiment, the protection module 100 is installed on the wall of the main control room, playing a role of physical isolation to prevent the leakage of radioactive substances and also avoiding the entry of pollutants in the external environment into the main control room. This module is made of high-strength and radiation-resistant materials and has good sealing performance. The transmission module 200 is arranged inside the protection module 100, and its main function is to load the objects to be transmitted. Inside the transmission module 200, a slide rail device 201 is equipped, allowing the object box 500 to move smoothly along the track, reducing friction and facilitating the operator to push it easily.

[0037] The ventilation module 300 is responsible for maintaining the air pressure balance inside and outside the protection module 100, and can effectively block pollutants such as dust and microorganisms while ensuring air circulation. The ventilation module adopts a positive pressure design, that is, the air pressure inside the protection module 100 is slightly higher than the outside, which can prevent external pollutants from entering and reduce the risk of radioactive substances spreading outward. To adapt to different usage scenarios, the ventilation module 300 also supports manual adjustment of the air volume to flexibly handle various situations. The purification module 400 is located at the position of the protection module 100 close to the outside of the main control room, mainly used for purifying the air entering or leaving the protection module 100. This module adopts a multi-stage filtration technology. First is a coarse pre-filter screen to remove large particles; second is a HEPA filter screen, which can effectively remove harmful gases and odors. It provides a healthy and safe working environment for the nuclear power plant staff.

[0038] The outer shape of the protection module 100 is preferably 50 cm in height, 60 cm in width, and 800 cm in length.

[0039] In summary, this object transfer device for the main control room of a nuclear power plant not only meets the basic object transfer requirements, but also reaches a relatively high level in terms of safety and reliability, providing a strong guarantee for the safe and stable operation of the nuclear power plant.

[0040] Among them, a radioactive monitor 600 is also installed inside the protection module 100 to detect the radioactive level of the objects inside the transmission module 200 and ensure safety standards.

[0041] In another embodiment, the transmission module 200 can adopt a robotic arm or a conveyor belt.

[0042] Install a multi-degree-of-freedom robotic arm, and control the robotic arm to grab and place the object box 500 through programming. It has high flexibility, can achieve the transfer of complex paths, and is suitable for objects of various shapes and sizes.

[0043] Install a conveyor belt system, and place the object box 500 on the conveyor belt for transmission. The transmission is stable, the load-bearing capacity is strong, it is suitable for the transfer of a large number or heavy objects, and the maintenance is relatively simple.

[0044] Embodiment 2

[0045] Reference Figures 1-5 , which is the second embodiment of the present invention. This embodiment provides an object transfer device for the main control room of a nuclear power plant. The protection module 100 includes a top plate 101, on which there are at least one inlet connection pipe 102 and at least one outlet connection pipe 103; an air filter 104 is arranged inside the top plate 101 for filtering the air entering or discharging; an outer door 105 and an inner door 106, both doors are equipped with door handles 107, and the design of the inner door 106 and the outer door 105 complies with the requirements of nuclear safety regulations regarding radiation shielding; a first side plate and a second side plate, and a fixing plate 108 is installed on each of the first side plate and the second side plate, and the fixing plate 108 can be connected to the wall of the main control room area, so as to firmly fix the protection module 100 at a designated position. The inlet connection pipe 102 and the outlet connection pipe 103 are both provided with adjustable valves.

[0046] In this embodiment, by connecting the fixing plate 108 to the wall of the main control room area, the stability of object transfer is ensured, and at the same time, the protection module 100 is fixed.

[0047] The inner door 106 and the outer door 105 cannot be opened simultaneously, which is to prevent the external environment (such as air, dust, etc.) from directly contacting the inside of the main control room.

[0048] The operation sequence is to close one door first before opening the other, ensuring that there is at least one physical barrier at any time to prevent potential dangerous substances from entering the main control room.

[0049] The transmission module 200 includes an object box 500, which is composed of a bottom plate and left, right, front and rear plates, forming a closed or semi-closed space; a slide rail device 201, one end of the slide rail device 201 is connected to both sides of the object box 500, and the other end is fixed on the protection module 100; a handle 202 is installed on the front and rear plates of the object box 500 for assisting the user to push or pull the object box 500. The slide rail device 201 includes a linear slide rail, a curved slide rail or a telescopic slide rail to adapt to different usage environments and requirements.

[0050] In this embodiment, the object box 500 is composed of a bottom plate, left, right, front and rear plates, forming a closed or semi-closed space. Such a design can effectively protect the internal items, and at the same time is convenient for observing and taking and placing items. Ensure the safety and integrity of the items during the moving process.

[0051] One end of the slide rail device 201 is connected to both sides of the object box 500, and the other end is fixed to the protection module 100. This connection method not only ensures the stability of the object box 500 but also enables it to move smoothly on the slide rail. According to different usage scenarios and requirements, the slide rail can be linear, curved, or telescopic. The linear slide rail is suitable for simple linear motion; the curved slide rail is applicable to situations where obstacles need to be bypassed; and the telescopic slide rail can adapt to different lengths of moving paths, providing greater flexibility.

[0052] The handle 202 is installed on the front and rear panels of the object box 500, and its specific position can be determined according to the actual usage situation. It provides a convenient operation point for users, enabling them to more easily push or pull the object box 500.

[0053] The ventilation module 300 includes an air inlet 301 opened in the main control room; an exhaust fan 302 located at the air inlet 301 for extracting air; an air duct 303 connecting the exhaust fan 302; a check valve 304 to prevent gas from flowing from the outside of the main control room to the exhaust fan 302 through the air duct 303; an air outlet 305 provided in the external area of the main control room for discharging the treated air; and a filter screen provided inside the top plate 101 of the protection module 100 for filtering the incoming air.

[0054] In this embodiment, the exhaust fan 302 continuously extracts the air inside the protection module 100 and discharges it outside the main control room, keeping the air pressure inside the protection module 100 at a relatively low level. This helps prevent the air (which may contain harmful substances or pollutants) inside the protection module 100 from leaking into the main control room. The main control room is designed to be a slightly positive pressure environment, that is, the air pressure inside the main control room is slightly higher than the external environment. This design can effectively prevent the unfiltered outside air from entering the main control room, thus protecting the cleanliness and safety inside the main control room. The check valve 304 is provided to ensure the directionality of air flow and prevent the outside air from directly entering the main control room without being treated, further ensuring the safety of the indoor environment. Through the above measures, not only can the environmental conditions inside the protection module 100 be effectively controlled and managed, but also the air quality inside the main control room can be ensured, while reducing the potential pollution to the external environment.

[0055] Embodiment 3

[0056] Refer to Figures 4-5, which is the third embodiment of the present invention. This embodiment provides an object transfer device for the main control room of a nuclear power plant. The purification module 400 includes: an airtight chamber 401 for providing a closed environment so that the air inside can be effectively purified; an air purification device disposed in the airtight chamber 401 for purifying the air in the airtight chamber 401 to remove harmful substances such as viruses, bacteria, and radioactive particles in the air; a movable door 403 connected to the airtight chamber 401 for controlling the entry and exit of personnel or objects into and out of the airtight chamber 401; and a sealing strip installed on the movable door 403 to ensure good sealing when the movable door 403 is closed and prevent unpurified external air from entering the airtight chamber 401. The air purification device includes one or a combination of HEPA filters, activated carbon filter layers, and ultraviolet germicidal lamps to achieve a multi-stage purification effect.

[0057] In this embodiment, the airtight chamber 401 provides a completely enclosed space to ensure the isolation of the internal air from the outside world, thereby effectively controlling and improving air quality.

[0058] The air purification device may include components such as HEPA filters, activated carbon filter layers, and ultraviolet germicidal lamps. These components can be used alone or in combination. HEPA filter: efficiently captures tiny particles such as dust, viruses, bacteria, etc. Activated carbon filter layer: adsorbs gaseous pollutants such as harmful gases like formaldehyde and smoke, and helps remove odors. Ultraviolet germicidal lamp: utilizes the bactericidal ability of ultraviolet light to achieve the purpose of disinfection. Multi-stage purification effect: By combining different technologies, the air can be purified more comprehensively, improving the purification efficiency and quality.

[0059] The movable door 403 serves as a passage for entering and exiting the airtight chamber 401, and at the same time, it is necessary to ensure good sealing performance in the closed state. The sealing strip is installed on the movable door 403. Ensure that when the movable door 403 is closed, an effective seal can be formed to prevent unpurified external air from entering the airtight chamber 401 and maintain the indoor air quality.

[0060] A method for using an object transfer device for the main control room of a nuclear power plant. When transferring an object from the outside to the main control room, the external operator needs to open the outer door 105 of the object transfer device. Place the object to be transferred into the transfer module 200. After ensuring that the object is correctly placed, close the outer door 105. The external operator presses a preset button to send a signal to the personnel in the main control room to inform that the object is ready to be received. After receiving the signal, the personnel in the main control room can safely open the inner door 106, take out the object, and close the inner door 106 in a timely manner. When transferring an object from the main control room to the outside, this process is generally the same as the above steps, only in the opposite direction.
