[0029] In the description of the present utility model, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like used in the present invention to indicate the orientation or position relationship is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0031] See also Figure 1 to Figure 2 It should be noted that the illustrations provided in this embodiment are only used to schematically illustrate the basic concept of the utility model, and the drawings only show the components related to the utility model rather than the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0032] The utility model provides a disassembly, wiping and decontamination workbench for disassembling, cleaning and decontaminating workpieces in nuclear power equipment, specifically Figure 1 and Figure 2As shown, the disassembly, wiping and decontamination workbench includes an operating table 10, a drain groove 20 and an exhaust system 30, wherein a support leg 11 is provided at the bottom of the operating table 10, and the support leg 11 is used to support the operating table 10, and a plurality of through holes extending from top to bottom are also provided on the operating table 10; the drain groove 20 is arranged at the bottom of the operating table 10, and a waste liquid discharge port 201 is provided on the bottom wall of the drain groove 20, and an exhaust port 101 is also provided at the bottom of the operating table 10, and the exhaust port 101 is communicated with the cavity between the operating table 10 and the drain groove 20; the exhaust system 30 includes a first exhaust pipe 301 and a second exhaust pipe 302, specifically, the first exhaust pipe 301 is connected to the exhaust port 101, the second exhaust pipe 302 is arranged above the operating table 10, and an exhaust hood 3021 is provided on the second exhaust pipe 302.

[0033] When the disassembly, wiping and decontamination workbench of the utility model is used, the decontamination equipment is placed on the operating table 10 for disassembly, and the first exhaust duct 301 and the second exhaust duct 302 of the exhaust system 30 are connected with the external exhaust device, through the suction effect of the first exhaust duct 301 at the bottom of the operating table 10 and the suction effect of the second exhaust duct 302 arranged on the top of the operating table 10, the dust and radioactive gas dropped when the workpiece is disassembled on the operating table 10 can be sucked away by the exhaust system; thereby, the air quality of the factory is guaranteed and the harm to the body of the operator is avoided; when wiping and cleaning the disassembled parts, since the operating table 10 is provided with a through hole, the cleaning waste liquid can flow through the through hole to the drain groove at the bottom of the operating table 10 by its own gravity, and then be discharged from the waste liquid outlet 201 opened on the bottom wall of the drain groove 20 to the outside for collection, thereby avoiding pollution to the environment.

[0034] Further, in order to improve the fluidity of the cleaning waste liquid discharged from the waste liquid outlet 201 on the bottom wall of the drain tank 20, preferably, as Figure 1 As shown, in this embodiment, the bottom wall of the drain groove 20 has a slope that slopes downward toward the middle of the bottom wall of the drain groove, and the waste liquid discharge port 201 is arranged in the middle of the bottom wall of the drain groove 20, that is, the drain groove 20 is funnel-shaped. Through this structural design, the cleaning waste liquid flowing from the operating table 10 into the drain groove 20 can be more smoothly gathered to the middle of the bottom wall of the drain groove 20, so that the cleaning waste liquid in the drain groove 20 can be more thoroughly discharged to the outside through the waste liquid discharge port 201.

[0035] Specifically, in this embodiment, the bottom wall of the drain groove 20 is inclined toward the middle at a slope of 5°. Of course, in other optional embodiments, those skilled in the art can set any slope according to specific needs.

[0036] Further, such as Figure 1As shown, in this embodiment, a filter 2010 is further provided at the waste liquid outlet 201, through which large impurities can be blocked, and parts falling from the through holes on the operating table 10 can also be blocked. Specifically, in this embodiment, the filtering capacity of the filter 2010 is 500 μm.

[0037] Further, such as Figure 1 As shown, a first damper 3010 is provided on the first exhaust pipe 301, and a second damper 3020 is provided on the second exhaust pipe 302. During operation, the first exhaust pipe 301 can be opened and closed by the first damper 3010, and the second exhaust pipe 302 can be opened and closed by the second damper 3020 as needed.

[0038] Furthermore, considering that there are some relatively large devices in the nuclear power plant that need to be placed on the operating table 10 for disassembly and cleaning, in order to avoid the interference of the second exhaust pipe 302 and the exhaust hood 3021 located above the operating table 10 with the placement of large devices and workpieces, preferably, in this embodiment, the second exhaust pipe 302 is rotatably arranged above the operating table 10. Through this structural design, when placing large devices and workpieces on the operating table 10, the second exhaust pipe 302 and the exhaust hood 3021 are rotated to the outside of the operating table in advance, thereby facilitating the placement of the devices. The structure is simple and the operation is convenient.

[0039] Further, in order to facilitate the rotation of the second exhaust pipe 302 and the exhaust cover 3021, as shown in FIG. Figure 1 As shown, a rotating handle 3022 is provided on the exhaust hood 3021, and the second exhaust pipe 302 can be driven to rotate by pulling the rotating handle 3022.

[0040] Specifically, in this embodiment, the outer dimensions of the operating table are 1500×1000×900 mm (length×width×height).

[0041] In summary, the disassembly, wiping and decontamination workbench of the utility model can avoid the spread of radioactive substances when disassembling and cleaning nuclear power equipment, and avoid the harm to the body of the operator. Therefore, the utility model effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.

[0042] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
