Description

Technical Field

[0001] The invention relates to the technical field of nuclear industry hot chambers, and in particular to an electrical interface device in a hot chamber. Background Art

[0002] The overall design concept of the equipment in the hot room is generally the same as the equipment design in the ordinary environment. The functional and process requirements are the dominant principles in the scheme design, structural design and spatial layout of a set of equipment. The inspection and maintenance of equipment in the special environment of the hot room are rarely considered.

[0003] Due to the requirements of their functional processes, various equipments need to realize certain motion functions or realize the control requirements of atmosphere, temperature, pressure, vacuum, etc., and be equipped with sensors, measuring instruments and other equipment. This requires that the equipment cannot be composed of simple mechanical structural components, but must be equipped with complex power supply cables, signal cables, control cables, and gas and water lines and pipelines. In existing designs, these connectors are generally distributed nearby in various places of the equipment body.

[0004] In a normal non-radiation environment, since people can directly contact the electrical interface equipment and operate the electrical interface equipment nearby, they can easily perform operations such as repair and replacement on the equipment.

[0005] When operating and maintaining the equipment in the hot room, due to the presence of radioactivity, personnel cannot directly contact the equipment. They must stand outside the shielded hot room and operate and maintain the equipment through the lead glass window using remote operating devices such as master-slave manipulators. Especially during equipment maintenance, equipment assembly and disassembly are required. The assembly of some equipment parts also requires high-precision fine operations. Equipment maintenance also requires the connection and disconnection of various electrical circuits, which requires a lot of electrical connector plugging and unplugging operations. As a remote mechanical operating device, the master-slave manipulator has poor flexibility. The end operating device can only perform clamping and tensioning actions. Compared with the flexibility of the complex joints of the human hand, its operability is very limited. Most installation, disassembly and electrical connector plugging and unplugging are very difficult for the master-slave manipulator.

[0006] Some mechanical mechanisms and electrical connectors are located far away or in blind spots, making it difficult for the master and slave manipulators to reach them, or other equipment blocks the human line of sight, making operation more difficult.

[0007] When the equipment fails and cannot be repaired by remote operation methods such as master-slave manipulators, it is necessary to perform a complex decontamination and cleaning procedure on the hot chamber, and then open the hot chamber for people to enter to perform equipment maintenance. At this time, it is necessary to consider the issue of personnel radiation protection. People need to wear radiation protection equipment such as gas suits, which reduces operational flexibility and has limited working time in the hot chamber. The hot chamber needs to be evacuated before the standard cumulative time is reached, and other personnel need to enter. The economic and time costs of this operation method are high, and there are also major safety hazards.

[0008] The above problems lead to poor scalability of the hot chamber function. After the hot chamber is put into operation, if you want to change the function of the equipment in the hot chamber or add a certain equipment, you must go through the same hot chamber decontamination procedure and then manually enter the hot chamber. Not only is the maintenance or replacement efficiency low, but it is also easy to cause harm to the human body. Summary of the invention

This method allows the installation and maintenance of components inside the hot chamber to be carried out outside the hot chamber, and the components can be moved out of the high radiation environment of the hot chamber. After the components are moved out of the hot chamber, they themselves no longer have strong radioactivity, so people can directly maintain the components through an easy-to-operate shielding glove box, which reduces the radiation received by the human body and can effectively avoid damage to the human body caused by the hot chamber radiation, making maintenance or replacement more efficient.

DETAILED DESCRIPTION

[0027] In the following detailed description, a large number of specific details are set forth in order to provide a thorough understanding of the present invention. However, those skilled in the art will appreciate that the present invention can be implemented without these specific details. In other cases, well-known methods, processes, components and circuits are not described in detail in order not to affect the understanding of the present invention.

[0028] See also Figures 1 to 4 As shown, according to an embodiment of the present invention, the electrical interface device in the hot chamber is arranged in the hot chamber 1, and a lifting port 2 is arranged on the top of the hot chamber 1. The electrical interface device in the hot chamber includes a base 3 arranged in the hot chamber 1, a motherboard 4 installed on the base 3, and a male board 5 plugged into the motherboard 4. A maintenance lifting position 6 and a shifting device for shifting or installing the motherboard 4 or the male board 5 are arranged at a position corresponding to the lifting port 2 on the base 3.

[0029] When a component of the electrical interface equipment in the hot chamber has a problem and needs to be repaired or replaced, the male board 5 or the female board 4 with the problem can be removed from the base 3 by the shifting device, and then placed on the maintenance hoisting position 6. The external hoisting equipment extends from the hoisting port 2 into the hot chamber 1, and the component located on the maintenance hoisting position 6 is hoisted out of the hot chamber 1, and then the component is replaced or repaired outside the hot chamber 1. This method allows the installation and maintenance of the components in the hot chamber 1 to be carried out outside the hot chamber 1, and the component can be moved out of the high radiation environment of the hot chamber 1. After the component is moved out of the hot chamber 1, it itself has no strong radioactivity, so the component can be directly maintained by a person through an easy-to-operate shielding glove box, which reduces the radiation received by the human body and can effectively avoid the damage to the human body caused by the radiation of the hot chamber. The maintenance or replacement efficiency is higher, and the maintainability of the equipment in the hot chamber is improved.

[0030] The shifting device may be a manipulator 7, the manipulator arm of the manipulator 7 is arranged in the hot chamber 1, and the operating end of the manipulator 7 is arranged outside the hot chamber 1. The manipulator 7 can operate the various components of the electrical interface equipment located in the hot chamber 1, so that the staff can complete the operation work without entering the hot chamber 1, effectively avoiding the operator from being radiated by the hot chamber, and improving the safety protection of the operator. Since the manipulator arm of the manipulator is located in the hot chamber 1 and the operating end is located outside the hot chamber, the operator can conveniently control the manipulator arm by operating the operating end, thereby completing the operation of the various components of the electrical interface equipment in the hot chamber, and can also conveniently place the damaged parts at the maintenance hoisting position 6.

[0031] The shifting device may also be a hoisting device 8 disposed in the hot chamber 1, the hoisting device 8 comprising a first slide rail 9, a second slide rail 10 and a suspension arm 11, the first slide rail 9 and the second slide rail 10 are arranged vertically and crosswise in the horizontal direction and are relatively slidable, and the suspension arm 11 is slidably disposed on the first slide rail 9 or the second slide rail 10. The suspension arm can be moved to various positions in the horizontal direction by the first slide rail 9 and the second slide rail 10, so that the parts can be smoothly placed from the installation position to the maintenance hoisting position 6, or the parts can be hoisted from the maintenance hoisting position 6 to the installation position for installation, and the operation is more flexible and convenient.

[0032] Preferably, columns 12 are fixedly arranged on two opposite inner walls of the heat chamber 1, the first slide rail 9 is fixedly arranged on the columns 12, the second slide rail 10 is slidably arranged along the length direction of the first slide rail 9, and the suspension arm 11 is slidably arranged along the length direction of the second slide rail 10. The columns can provide support for the arrangement of the first slide rail 9, so that the first slide rail 9 can stably stay at a preset height. The suspension arm 11 is movable along the length direction of the second slide rail 10, and can cooperate with the displacement of the second slide rail 10 on the first slide rail 9 to achieve flexible adjustment of the hoisting position of the suspension arm 11. There can be two columns 12 on each side, which are respectively supported at both ends of the first slide rail 9 on that side, thereby improving the stability of the installation structure of the first slide rail 9. The columns 12 can be fixedly arranged on the inner wall of the heat chamber 1 by bolts, or can be directly welded to the inner wall of the heat chamber 1.

[0033] In order to facilitate the adjustment of the position of the second slide rail 10 on the first slide rail 9, a gear is provided on the second slide rail 10, and a rack is provided on the first slide rail 9, and the gear is meshed with the rack. A driving motor is also provided on the second slide rail 10, and the driving motor is connected to the gear. By controlling the direction of the driving motor, the sliding position of the second slide rail 10 on the first slide rail 9 can be conveniently adjusted. The displacement of the second slide rail 10 on the first slide rail 9 can also be achieved by various methods such as chain drive or belt drive, and can also be achieved by telescopic mechanisms such as telescopic cylinders. The control of the driving motor can be remotely controlled by a controller set outside the hot room.

[0034] A displacement trolley 13 is provided on the second slide rail 10, and the boom 11 is hoisted on the displacement trolley 13. A signal receiver can be provided on the displacement trolley 13, and a signal transmitter can be provided on an outdoor controller. The controller can send a control command to the displacement trolley 13 through the signal transmitter to control the moving position and moving direction of the displacement trolley 13, so that the boom 11 can reach an accurate hoisting position. The displacement trolley 13 has the advantages of flexible movement, convenient adjustment, small friction, etc., and the adjustment is more flexible.

[0035] Preferably, the boom 11 is telescopically arranged on the displacement trolley 13. The boom 11 is telescopically arranged on the displacement trolley 13. When the boom 11 moves following the displacement trolley 13, the boom 11 can be folded to avoid interference between the boom 11 and other components, and the displacement adjustment of the boom 11 is not affected by the position of the components below it, so that the position adjustment strategy of the boom 11 can be more flexible and convenient, and a more appropriate adjustment route can be selected to improve the adjustment efficiency and reduce the difficulty of adjustment. When the boom 11 reaches the lifting position, the boom 11 can be controlled to extend, and then the boom 11 can lift the components that need to be repaired, and then the displacement trolley 13 can be controlled to lift the boom 11 to the maintenance lifting position 6 for subsequent operations. When it is necessary to lift the components from the maintenance lifting position 6 to the installation position, the above-mentioned method can also be used for operation. After the boom 11 reaches the installation position, it can be slowly extended to a suitable length, and then the motherboard 4 or the male board 5 is lowered to the installation position. The motherboard 4 or the male board 5 is pressed down under the action of gravity to complete the plug-in cooperation with other components. The operation is simple and convenient.

[0036] Preferably, there are multiple motherboards 4, and the specifications of the multiple motherboards 4 are consistent. Since the specifications adopted by the motherboards 4 are consistent, the modular design of the motherboards 4 can be realized, the processing cost of the motherboards 4 can be reduced, and the standardization of the design of the motherboards 4 can be improved, and the difficulty of matching the male board 5 with the motherboard 4 can be reduced, so that the installation interface between the electrical interface equipment and the wall of the hot chamber is reduced, the coupling degree between the equipment design and the hot chamber design is reduced, and the reliability of the equipment and the hot chamber is improved.

[0037] The present invention designs the electrical interface board to a uniform specification, designs the number of connectors according to the requirements of the maximum module, and leads all connector pins to the outside of the heat chamber after welding or crimping. Each module is wired and interfaced outside the heat chamber according to its actual requirements, and the redundant pins are reserved for backup.

[0038] Since the motherboard 4 adopts the same specifications, it is more convenient to plug and unplug the electrical connectors and install them more conveniently when maintaining the equipment in the hot room. Generally, only part of the multiple motherboards 4 will be used, and the other motherboards 4 can be used as spare motherboards, so that when a new male board 5 is installed or an individual motherboard 4 fails, the male board 5 can be installed on other motherboards 4 in time, so that the electrical interface equipment in the hot room has better expansion performance. When the hot room needs to add functional modules, the new module only needs to design a male board 5 of the unified electrical interface board, which is hoisted into the hot room and placed on the spare motherboard 4, and the wiring configuration is performed outside the hot room according to the pre-defined pins.

[0039] Multiple motherboards 4 can make the motherboards in the hot chamber 1 interchangeable. When a single motherboard 4 fails, the male board 5 on the motherboard 4 can be directly moved to other motherboards 4, and then the failed motherboard 4 can be moved out of the hot chamber 1 for repair, so that the equipment can still maintain normal operation, reduce the fault repair time and the impact of the fault repair process on the use of the equipment, reduce the time cost of hot chamber maintenance, and reduce economic costs.

[0040] The motherboard 4 is provided with a power line socket 14, a signal line socket 15, a water line socket 16, a gas line socket 17 and / or a vacuum line socket 18, and the male board 5 has connectors corresponding to these sockets, which can facilitate the matching connection between the male board 5 and the motherboard 4.

[0041] Preferably, the male board 5 is provided with a guide post 19 extending toward the female board 4, and the female board 4 is provided with a guide hole 20 matched with the guide post 19. When the male board 5 is installed on the female board 4, the guide post 19 can be used to guide and position the installation of the female board 4 and the male board 5, so as to ensure the correctness of the electrical connector until the connection, improve the plug-in matching efficiency of the female board 4 and the male board 5, and save installation time.

[0042] The description of the above embodiments is only used to help understand the method of the present invention and its core concept; at the same time, for a person skilled in the art, according to the concept of the present invention, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation of the present invention.
