Description

Technical Field

[0001] The utility model relates to the technical field of plasma, in particular to a fool-proof electron beam structure. Background Art

[0002] In the mid-20th century, with the rapid advancement of science and technology, humanity gradually mastered the art of controlling electron beams. Electron beams are high-energy particle beams that can be precisely focused and manipulated. This technology holds enormous potential in industrial processing, medical treatment, and scientific research. Electron beam welding, as an advanced welding technology, was first used in the aerospace and nuclear industries. Its high energy density and precise controllability enable welding at extremely high temperatures, achieving connections unattainable by traditional welding methods. However, early applications also exposed several problems and safety hazards. Learning from these early mistakes, scientists and engineers realized the need to introduce more stringent safety measures and foolproofing techniques to ensure the reliability and safety of electron beam equipment in various applications. The development and implementation of foolproofing technology has become a critical area of electron beam equipment design. The core concept of foolproofing is to reduce the possibility of human error by designing and implementing multiple physical and logical protection mechanisms, and to automatically correct potential dangerous situations.

[0003] A utility model search, patent number CN205392180U, discloses a foolproof electron beam radiation shielding structure and electron beam curing device. This foolproof electron beam radiation shielding structure includes a first shielding body, a second shielding body, and a fixing member. The first and second shielding bodies are provided with a mounting structure, and the fixing member is used to cooperate with the mounting structure to detachably connect and fix the first and second shielding bodies. The mounting structure has a preset position. When the fixing member is assembled to the position, the first and second shielding bodies are combined into place. The fixing member is provided with a magnetic member. A magnetic induction switch is provided at a preset position on the first or second shielding body. The magnetic induction switch is used to connect between the power supply and the electron accelerator. When the fixing member is assembled to the position, the magnetic induction switch is triggered and closed by the magnetic member. This utility model is not easily deceived during use, ensuring the integrity of the shielding structure.

[0004] However, simply adding a shielding body cannot completely fool-proof the equipment, and accidents may still occur due to human factors. Therefore, we propose a fool-proof electron beam structure. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the background technology and to design a fool-proof electron beam structure.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is a fool-proof electron beam structure, including a door magnetic alarm, a spring switch, a magnet, a hinge, leaded glass, a sealing rubber ring door frame, a physical door lock, a device body, and a door frame. It is characterized in that a spring switch and a magnet are respectively installed inside the door magnetic alarm, and the door magnetic alarm is respectively installed on the surface of the device body and the door frame through magnetic connection. A piece of leaded glass is installed on the surface of the door frame, and the door frame and the device body are physically connected by the hinge to fit the sealing rubber ring door frame, and the door frame and the device body are connected by the hinge to install a physical door lock on the outer surface.

[0007] Preferably, a piece of leaded glass is inlaid inside the door frame.

[0008] Preferably, the spring switch and the magnet are the main internal structures of the door magnetic alarm.

[0009] Preferably, the physical door lock closes the device body and the door frame.

[0010] Beneficial effects:

[0011] The present invention provides a foolproof electron beam structure with the following beneficial effects. Through its structural design, the device is composed of two parts: a door magnetic alarm switch and a magnet. The switch part is connected by a reed switch via a lead wire. It is shaped and packaged; the magnet part is a magnet with a corresponding magnetic field strength encapsulated in a plastic or alloy shell. When the two are separated or approached to a certain distance, the switch is disconnected, thereby sensing the change in the position of the object. It can be used in conjunction with the access control controller to enable an alarm when the door is not closed for a long time. The use of a sealing rubber ring door frame and leaded glass can prevent air from entering when observing the electron beam, thereby protecting the electron beam source and processing materials. By preventing misoperation and accidental opening, the mechanical interlock switch can reduce the risk of damage to the equipment, thereby extending the service life of the equipment and reducing maintenance and replacement costs.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] In the description of this utility model, it should be noted that the terms "upper / lower end," "inner," "outer," "front end," "rear end," "both ends," "one end," "the other end," and the like, indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "set / mounted," "sleeved," "connected," etc., should be understood in a broad sense. For example, "connected" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection through an intermediate medium; it may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0019] See also Figure 1-2 The utility model provides a technical solution: including a door magnetic alarm 1, a spring switch 1.1, a magnet 1.2, a hinge 3, leaded glass 4, a sealing rubber ring door frame 5, a physical door lock 6, a device body 7, and a door frame 8. It is characterized in that the spring switch 1.1 and the magnet 1.2 are respectively installed inside the door magnetic alarm 1, and the door magnetic alarm 1 is respectively installed on the surface of the device body 7 and the door frame 8 through magnetic connection. A piece of leaded glass 4 is installed on the surface of the door frame 7. The door frame 8 and the device body 7 are physically connected by the hinge 3 to fit the sealing rubber ring door frame 5. The door frame 8 and the device body 7 are connected by the hinge 3 to install a physical door lock 6 on the outer surface.

[0020] The door frame 7 is inlaid with a piece of leaded glass 3. Electron beam equipment generates high-energy radiation, particularly X-rays, during operation. This radiation poses a potential hazard to operators and the surrounding environment. Due to its high density and high atomic number of lead, leaded glass effectively absorbs and shields this radiation, preventing leakage.

[0021] The spring switch 1.1 and magnet 1.2 form the main internal structure of the door magnetic alarm 1. The magnet, as one of its core components, uses the properties of a magnetic field to detect the door's status. When the door is closed, magnet 1.2 is in close proximity or contact with a magnetic sensor mounted on the door frame, completing a circuit. When the door is opened, the magnet moves away from the sensor, breaking the circuit and triggering the alarm. The spring switch 1.1 is an electromagnetic switch consisting of two or more metal reeds. These reeds separate in the absence of a magnetic field, but attract each other in the presence of a magnetic field, closing the circuit. The spring switch is typically enclosed in a glass or plastic tube. When a magnet approaches, the magnetic force on the reeds closes the circuit. When the magnet moves away, the elastic force on the reeds separates, breaking the circuit.

[0022] The physical door lock 6, which closes the device body 7 and door frame 8, plays a crucial role in ensuring the safe operation and protection of the device. It ensures that the protective door of the device body 7 cannot be opened arbitrarily during operation, thereby preventing electron beam leakage caused by accidental operation. The physical door lock 6 can be linked to the electron beam device's control system. If it detects that the door is unlocked or forced open, the device will immediately shut down to avoid danger. The physical door lock 6 mechanically secures the door to the door frame 8, preventing it from accidentally opening due to vibration or external forces. Once locked, the door frame and the device body 7 form a complete protective barrier, increasing the overall protection level and ensuring that radiation does not leak into the operating area. Once locked, the physical door lock 6 ensures the enclosure of the device body 7, preventing the electron beam and radiation from leaking into the external environment. The physical door lock 6 is integrated with the electron beam device's radiation shielding system to enhance overall protection. The physical door lock 6 ensures a tight fit between the door and the door frame 8, preventing radiation leakage due to the door gap. Even if a fault occurs inside the device 7, the tight fit between the physical door lock 6 and the door frame 8 can provide additional protection to prevent radiation leakage.

[0023] Through the use of wires by those skilled in the art, all electrical components in this case are connected to their corresponding power supplies, and appropriate controllers should be selected according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the following working principle, in which the electrical components are electrically connected in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control.

[0024] In this embodiment:

[0025] Mount the magnetic sensor on the door frame and the magnet on the door, ensuring they align when the door is closed. Connect the door magnetic alarm to the equipment's main control system or an independent alarm system. The alarm system immediately sounds an alarm if the door is opened. The door magnetic alarm continuously monitors the door's status and, upon detecting a door opening, immediately sends an alarm signal to the operator and the control system. The alarm system can be integrated with the electron beam system's control system. Once the door magnetic alarm triggers an alarm, the control system automatically shuts down the electron beam system to prevent electron beam leakage. The door magnetic alarm monitors the door's status in real time, while the physical door lock ensures that the door is physically locked. The two complement each other, providing dual security. Integrating the door magnetic alarm and physical door lock into the electron beam system's main control system provides comprehensive security control. Upon detecting any anomalies, the system automatically takes action to ensure safety. The door magnetic alarm confirms the door is closed, and the physical door lock locks the door before the electron beam system can be activated. The door magnetic alarm triggers an alarm, immediately shutting down the control system, while the physical door lock prevents the door from being easily opened.

[0026] The combination of a door magnetic alarm and a physical door lock effectively prevents electron beam leakage, ensuring the safety of operators and equipment. The door magnetic alarm provides real-time monitoring and alarm functions, while the physical door lock provides physical protection through mechanical means. The two complement each other to form a complete safety protection system. This dual insurance mechanism not only improves the safety of electron beam equipment but also provides a solid guarantee for its reliable operation.

[0027] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include," "comprise," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations. The phrase "includes an element defined by..." does not exclude the presence of other identical elements in the process, method, article, or device that includes the element.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
