[0039] Please refer to Figures 1 to 5 .

[0040] In the specific embodiment, the workbench assembly provided by the present utility model includes a box body 11. The top of the box body 11 is provided with a horizontally arranged work panel 12. The interior of the box body 11 has a shelter cavity 111 capable of accommodating a staff member. The side wall of the box body 11 has a shelter opening 112 for the staff member to enter and exit the shelter cavity 111, and a shelter door panel 113 is arranged to open and close on the shelter opening 112; the box body 11, the work panel 12 and the shelter door panel 113 are all made of lead plates.

[0041] During its operation and use, under normal working conditions for daily use, the staff member can place tooling and related tools and other equipment on the work panel 12 to implement corresponding daily production operations.

[0042] When an accident such as a nuclear leak occurs in the surrounding working environment, the staff member can quickly open the shelter door panel 113, enter the shelter cavity 111 through the shelter opening 112, and then close the shelter door panel 113 again to block the shelter opening 112. Since the box body 11, the work panel 12 and the shelter door panel 113 are all components made of lead plates, and lead plates have excellent radiation protection and corrosion resistance properties, the staff member in the shelter cavity 111 is thus under all-round protection.

[0043] After the nuclear leakage and other accidents in the external environment are handled and the external working conditions have returned to safety, or when the rescue personnel have arrived at the scene and taken corresponding rescue measures, the staff can reopen the shelter door panel 113 and leave the shelter cavity 111 through the shelter opening 112.

[0044] It can be seen that on the basis of being able to meet the basic workbench functions and the corresponding equipment supporting operations, the workbench assembly can also serve as a temporary shelter device in the event of a nuclear leakage accident or other situations, providing a reliable safe shelter space for the staff who are too late to escape, thus ensuring the personal safety of the staff, avoiding the staff being directly exposed to the external environment and being harmed by excessive nuclear radiation, etc., and effectively ensuring the safety of the staff's production operations.

[0045] Correspondingly, it also enables the component structure of the workbench assembly to meet the application requirements of various working conditions, improves its supporting application effect and safety guarantee for working conditions such as nuclear power plants, and correspondingly improves the working condition adaptability of the workbench assembly, making the operation and use in different working conditions safer and more convenient.

[0046] Generally, the work panel 12 and the shelter door panel 113 can be directly processed from lead plates, while the box body 11 can be formed by splicing and assembling multiple lead plates. In practical applications, the specific shapes, structures and processing and forming methods of the box body 11, the work panel 12 and the shelter door panel 113 can also be flexibly selected and adjusted according to the actual working condition requirements, but the processing base material should be selected from materials with good radiation protection and corrosion resistance such as lead plates to ensure the temporary shelter effect and safety of the workbench assembly and meet the emergency shelter requirements under extreme working conditions such as nuclear leakage.

[0047] Specifically, a traveling device is provided at the bottom of the box body 11. Through this traveling device, the box body 11 and even the entire workbench assembly can be moved to the target work station, so as to adjust the layout position of the workbench assembly when necessary, thereby meeting the application requirements under different working conditions.

[0048] Especially in the event of special working conditions such as a nuclear leakage accident, when the staff have entered the shelter cavity 111 for temporary shelter, if the rescue personnel have come to the scene, the workbench assembly with the staff inside can be directly moved to a safe environment, and then the shelter door panel 113 can be opened so that the staff can leave the shelter cavity 111 through the shelter opening 112, thereby further ensuring the operation safety during the rescue process, reducing the risk of the staff being harmed by nuclear radiation, etc., and ensuring the personal safety of the staff.

[0049] More specifically, the walking device is the universal wheel 13 arranged at the bottom of the box body 11. Specifically in actual assembly applications, these universal wheels 13 can be aligned and installed at the respective top corners or the respective edge parts of the bottom of the box body 11, or universal wheels 13 can be correspondingly arranged at the respective top corners and the respective edge positions of the bottom of the box body 11, so as to optimize the stress distribution at the bottom of the box body 11, improve the overall weighing capacity of the box body 11, and optimize the action efficiency and movement tracking performance during its overall movement.

[0050] Furthermore, the box body 11 is a cuboid, the shelter opening 112 is located on the front side wall of the box body 11, the shelter door panel 113 is a front panel detachably arranged on the front side wall of the box body 11, the assembly end of the front panel is hinged to the box body 11, and the action end of the front panel is detachably connected to the box body 11.

[0051] Generally, the front panel is a rectangular plate, and the assembly end and the action end of the front panel are respectively located on a set of opposite sides of the front panel. Considering the conventional operating habits, the assembly end and the action end of the front panel are respectively arranged on a set of horizontally symmetric opposite sides, so that the rotation axis of the assembly end of the front panel extends in the vertical direction, enabling the front panel to rotate about a fixed axis in the horizontal direction, thereby realizing the opening and closing of the front panel in the horizontal direction.

[0052] It is not difficult to understand that, except for the side walls of the box body 11 on the side where the shelter door panel 113 is located, the side walls and the bottom plate and other structural components at other positions on the box body 11 can be welded and fixed to each other to ensure the overall structural strength and load-bearing capacity of the box body 11.

[0053] Of course, considering the different requirements of the assembly space layout in actual applications, the shelter opening 112 can also be correspondingly arranged on the left side wall, the right side wall or the rear side wall of the box body 11, and the shelter door panel 113 can also be correspondingly adjusted to a left panel, a right panel or a rear panel.

[0054] Specifically in actual applications, a lighting lamp 121 cooperating with the shelter cavity 111 is arranged at the bottom of the working panel 12, and a lighting switch 114 capable of controlling the on-off of the lighting lamp 121 is arranged on the inner wall of the shelter cavity 111. When the staff takes shelter in the shelter cavity 111 temporarily due to accidents such as nuclear leakage in the external environment, the lighting lamp 121 can be controlled to be turned on through the lighting switch 114 so as to provide appropriate lighting for the internal space of the shelter cavity 111, thereby meeting the basic environmental requirements in the shelter cavity 111; when there is no need to illuminate the internal environment of the shelter cavity 111, the lighting lamp 121 can be controlled to be turned off through the lighting switch 114 to reduce the energy consumption of the workbench assembly and save energy.

[0055] Under normal circumstances, in order to avoid misoperations caused by a dark environment, after the staff enters the shelter cavity 111, the lighting lamp 121 can be turned on before the shelter door panel 113 is closed again, so as to prevent the shelter cavity 111 from being in a completely dark state after the shelter door panel 113 is closed and completely blocks the shelter opening 112, resulting in the staff being unable to touch the lighting switch 114 in time and accurately, which affects the timely turning on of the lighting lamp 121.

[0056] Correspondingly, a positioning device 115 communicatively connected to the nuclear power plant control system and a positioning switch 116 capable of controlling the opening and closing of the positioning device 115 can also be provided on the inner wall of the shelter cavity 111. When the staff takes temporary refuge in the shelter cavity 111 due to accidents such as nuclear leakage in the external environment, the positioning device 115 can be activated by controlling the positioning switch 116, so as to send a distress alarm signal and the positioning information of the current position of the workbench assembly to the control system of the nuclear power plant, so that the monitoring personnel of the nuclear power plant control system can quickly understand the location of the accident and the positioning of the personnel in need of rescue, and then arrange rescue personnel to quickly rush to the location where the workbench assembly is located, so as to quickly rescue the staff taking refuge in the shelter cavity 111; if there is no need to send positioning and alarm distress information about the location of the workbench assembly, the positioning device 115 can be stopped by controlling the positioning switch 116 to reduce the energy consumption of the workbench assembly and save energy.

[0057] In practical applications, the positioning device 115 can be a Bluetooth signal module or a pulse signal module, and its specific type can be flexibly selected and adjusted according to actual working conditions. In principle, as long as it can ensure the smooth transmission of alarm distress and positioning signals.

[0058] Generally, a storage battery can be integrated inside the box body 11 of the workbench assembly to supply electrical energy to the positioning device 115 and the lighting lamp 121, ensuring the reliable operation of related electrical devices. Under normal working conditions, the storage battery can be charged by using the conventional power supply system in the nuclear power plant system to ensure that the power of the storage battery is always sufficient for emergency use in case of emergencies.

[0059] In addition, an emergency storage rack 117 can also be arranged in the shelter cavity 111 for storing some emergency food and medicine, so that the staff can maintain their vital signs and perform some simple self-help when taking refuge in the shelter cavity 111, waiting for the arrival of rescue personnel.

[0060] Correspondingly, a ventilation opening 118 capable of linking the shelter cavity 111 with the external gas environment should be arranged on the bottom plate of the box body 11 to prevent the staff from suffocating when taking refuge in the shelter cavity 111.

[0061] On the other hand, an extension board 14 is provided at the top of the box body 11 in an openable and closable manner, which can be flipped to a horizontal state to cover the working panel 12; the assembly end of the extension board 14 is hinged to the top edge of the box body 11, the action end of the extension board 14 is detachably connected to the top of the box body 11, and the assembly end and the action end of the extension board 14 are located at both ends of the extension board 14 respectively. Under normal working conditions, the extension board 14 can be flipped up to a state where it is generally arranged vertically, and tools and other equipment required for daily operations can be arranged on the main structure of the extension board 14 for easy access; at the same time, the extension board 14 can also be used as a unilateral shield for the working panel 12 to meet the operation requirements under different working conditions and avoid the influence of the external environment on the operation environment on the working panel 12.

[0062] Generally, the extension board 14 is also a component made of lead plate. When the staff takes shelter in the shelter cavity 111 due to accidents such as nuclear leakage in the external environment, the extension board 14 can be folded to a horizontal state and the extension board 14 can completely cover the top of the box body 11, so as to use the extension board 14 to form an upper shield for the workbench surface and the shelter cavity 111 in the box body 11, thereby further improving the shielding and protection ability of nuclear radiation and corrosive substances above the shelter cavity 111, further improving the safety of the staff in the shelter cavity 111, and further improving the overall emergency safety shelter effect and personal safety guarantee ability of the workbench assembly.

[0063] Generally, a handle or a handle groove 141 can be arranged at the edge of the extension board 14, so that the staff can smoothly fold the extension board 14 by holding the handle or the handle groove 141, improving the operation convenience and operation efficiency of the extension board 14.

[0064] On this basis, a limit support device is connected between the extension board 14 and the box body 11, which can keep the extension board 14 in an unfolded state. After the extension board 14 is flipped up to a state where it is generally vertical, a structural support can be formed between the extension board 14 and the box body 11 through the limit support device, so as to keep the extension board 14 in the current generally vertical arrangement state, avoiding the extension board 14 suddenly folding down and injuring the staff or damaging the equipment on the working panel 12 when the staff performs processing operations at the working panel 12, thereby improving the operation and use safety of the workbench assembly.

[0065] Furthermore, the limit support device includes a movable strut 15 and a lock 142. The lock 142 protrudes from the side wall of the extension board 14. The assembly end of the movable strut 15 is hinged to the outer wall of the side part of the box body 11, and the connection end of the movable strut 15 has a clamping groove 151 that can be aligned and clamped on the lock 142 to realize the disassembly and assembly cooperation between the connection end of the movable strut 15 and the lock 142.

[0066] After turning up the extension board 14 to a substantially vertical state, the movable support rod 15 can be moderately folded so that the card slot 151 is aligned with the lock catch 142, and the connection end of the movable support rod 15 is pressed against the lock catch 142 until the lock catch 142 is embedded in the card slot 151, thereby completing the reliable connection between the movable support rod 15 and the extension board 14, and using the movable support rod 15 to form a reliable structural support for the extension board 14 so that the extension board 14 maintains a state of being arranged substantially along the vertical direction.

[0067] When it is necessary to turn down and fold the extension board 14 to a horizontal state, the connection end of the support rod can be pulled upward in the reverse direction so that it moves away from the lock catch 142 until the lock catch 142 is disengaged from the card slot 151, thereby releasing the structural support and limit of the extension board 14, so that the extension board 14 can be freely and smoothly turned down to a horizontal arrangement state, thereby using the extension board 14 to form an upper shielding and protection for the box body 11 and the working panel 12, and at the same time, the movable support rod 15 can be reset to prevent structural interference and blockage from occurring during the flipping action process of the extension board 14.

[0068] It is not difficult to understand that in practical applications, the width of the slot opening of the card slot 151 should not be greater than the outer diameter of the lock catch 142 to prevent the lock catch 142 from being disengaged from the card slot 151 after being installed in place; and the inner diameter of the inner cavity of the card slot 151 should not be less than the outer diameter of the lock catch 142 to avoid excessive local stress concentration after the lock catch 142 and the card slot 151 are installed in place and optimize the matching effect between the card slot 151 and the lock catch 142.

[0069] In addition, a number of extension storage slots 143 capable of accommodating tools are provided on the extension board 14. The extension storage slots 143 can be used to store tools and other equipment required in daily production and processing operations so that the staff can conveniently access them when performing operations at the working panel 12.

[0070] In summary, for the workbench assembly provided in the present utility model, during its operation and use, under normal working conditions for daily use, workers can place tooling and related tools and other equipment on the work panel to perform corresponding daily production operations. When accidents such as nuclear leakage occur in the surrounding working environment, workers can quickly open the shelter door panel, enter the shelter cavity through the shelter opening, and then close the shelter door panel again to block the shelter opening. Since the box body, the work panel, and the shelter door panel are all components made of lead plates, and lead plates have excellent radiation protection and corrosion resistance properties, the workers in the shelter cavity are thus protected in all aspects. After the nuclear leakage and other accidents in the external environment are handled and the external working environment has returned to safety, or when the rescue personnel have arrived at the scene and taken corresponding rescue measures, the workers can open the shelter door panel again and leave the shelter cavity through the shelter opening. Thus, it can be seen that on the basis of being able to meet the basic workbench functions and the corresponding equipment supporting operation and use, the workbench assembly can also serve as a temporary refuge device in the event of nuclear leakage accidents and other situations, providing a reliable safe shelter space for workers who have no time to escape, thereby ensuring the personal safety of workers, preventing workers from being directly exposed to the external environment and being harmed by excessive nuclear radiation, etc., and effectively ensuring the safety of workers' production operations. Correspondingly, it also enables the component structure of the workbench assembly to meet the application requirements of various working conditions, improves its supporting application effect and safety guarantee for working conditions such as nuclear power plants, and correspondingly improves the working condition adaptability of the workbench assembly, making its operation and use in different working environments safer and more convenient.
