Description
Technical Field
The invention belongs to the field of nuclear power, and particularly relates to a personnel gate buffer device of a nuclear power plant.
Background
The main function of the personnel lock of the nuclear power plant is to allow personnel and small equipment to pass through when the reactor is running or is shut down thermally, without damaging the sealing function of the containment. The device also has the following functions under special conditions: under the accident condition, the emergency evacuation exit is used as an exit for emergency evacuation of personnel; when cold shutdown is performed, the gate is unlocked, and the inner door and the outer door are opened simultaneously, so that the gate can be used as a passage for personnel and small equipment to enter and exit the containment vessel; when the containment is subjected to sealing and strength tests, the containment can be used as a pressurization/decompression chamber.
The personnel gate structure comprises a cylinder body, a sealing door (an inner door and an outer door), a lifting door step, a channel bottom plate and other structures, and further comprises a transmission mechanism, an interlocking mechanism, a pressure balance mechanism, a locking mechanism, an outer door hinge mechanism, an inner door hinge mechanism and a jacking mechanism for driving the structures. When the personnel gate sealing door is closed, the door plate rotates and closes at a certain speed, and a larger rebound force and rebound displacement exist at the moment when the door plate contacts the door frame. The existing buffer mechanism cannot fully buffer the impact force of the door plate, so that the sealing door rebounds, and the sealing is not tight after the sealing door of the personnel gate is closed. Meanwhile, the service life of the transmission mechanism is influenced by instantaneous rebound impact when the sealing door is closed. Because the personnel gate belongs to a part of the pressure-bearing boundary of the nuclear containment and penetrates through the inner containment and the outer containment, the untight closing of the sealing gate can cause the failure of the pressure-bearing boundary of the nuclear containment, and serious results are caused.
In view of this, it is necessary to provide a personnel lock gate buffer device for a nuclear power plant, which ensures the normal closing of a personnel lock gate sealing door and maintains the integrity of a pressure-bearing boundary of a containment vessel.

In the illustrated embodiment, the auxiliary member is a nut 150, the first mandrel 148 is a bolt, one end of the bolt is connected to the suction plate connection plate 142, the other end of the bolt passes through the fixing hole of the door panel connection plate 144 and then is connected by the nut 150, and the first spring 146 is interposed between the suction plate connection plate 142 and the door panel connection plate 144 to limit the expansion and contraction of the first spring 146 and further limit the distance between the suction plate connection plate 142 and the door panel connection plate 144. In another embodiment of the present invention, a bolt hole is formed at one end of the first mandrel 148 after passing through the fixing hole of the door panel connecting plate 144, and one end of the first mandrel is connected to the suction plate connecting plate 142, and the first spring 146 is interposed between the suction plate connecting plate 142 and the door panel connecting plate 144 by inserting a bolt after the end having the bolt hole passes through the fixing hole of the door panel connecting plate 144.
Referring to fig. 3 and 4, the first spring 146 is used for horizontal impact damping, and when the door 30 is closed, it rotates toward the doorframe 20 at a certain speed to impact and close, and the damping device can sufficiently absorb the part of kinetic energy. Therefore, in designing, after the cushioning device is assembled, the distance from the rear surface of the door panel connecting plate 144 to the rear surface of the sliding plate 124 (i.e., the distance from the rear surface of the door panel connecting plate 144 to the door frame 20) is greater than the thickness of the door panel 30, so that cushioning can be started when the door panel 30 is not in contact with the door frame 20, and the impact force is reduced by the contact, so that the impact force of the door panel 30 can be sufficiently absorbed.
In addition, the electromagnetic chuck 120 is powered on in the buffering process, the chuck structural member 12 is tightly attached to the suction plate structural member 14, and the door panel 30 can be limited from rebounding and moving.
Because the suction plate structure 14 is designed with the first spring 146 for compression buffering, the suction plate structure 14 can be quickly reset after the door panel 30 is opened, and the reuse is not affected. Because the second spring 130 is arranged below the suction cup base plate 122 for compression buffering, after the sealing door panel 30 is opened, the whole body formed by connecting the electromagnetic suction cup 120 and the suction cup connecting plate 122 can be quickly reset, and the reuse of the suction cup structural member 12 is not influenced.
Meanwhile, the power supply time of the electromagnetic chuck 120 is controlled by controlling the power switch, before or when the sealing door panel 30 is in contact with the door frame 20, the electromagnetic chuck 120 is electrified, the electromagnetic chuck 120 and the suction plate 140 are tightly attached, after the electromagnetic chuck 120 and the suction plate 140 are tightly attached for a period of time (the time is not more than the total time of vertical sliding of the gate), the power supply is cut off, the electromagnetic chuck 120 has no suction force, and the personnel gate sealing door panel 30 can continue to fall back. Meanwhile, the electromagnetic chuck 120 is an electronic product, and if the electromagnetic chuck is in a power-on state for a long time, the service life of the electromagnetic chuck is affected, and the electromagnetic chuck 120 is powered off after the door panel 30 is closed in place, so that the service life of the electromagnetic chuck is not affected.
Compared with the prior art, the personnel gate buffer device for the nuclear power plant has the following beneficial technical effects:
1) the structure is simple, and the design is convenient;
2) the problems of rebound force and rebound displacement caused by overlarge horizontal impact force when the personnel gate sealing door is closed are solved, so that the personnel gate sealing door can be normally closed, the sealing performance of gate equipment is ensured, and the integrity of a pressure-bearing boundary of the nuclear containment vessel is maintained;
3) the problem of the vertical slip of personnel's gate sealing door with the door frame laminating is solved, original buffer's frictional wear problem has been reduced.
The present invention can be modified and adapted appropriately from the above-described embodiments, according to the principles described above. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and variations of the present invention should fall within the scope of the claims of the present invention. Furthermore, although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
