Description

TECHNICAL FIELD

[0001] The utility model relates to nuclear safety emergency technical field especially is a kind of portable self-advancing nuclear decontamination copolymer film recovery device. BACKGROUND

[0002] It is known that with the increasing perfection of nuclear energy application technology, the development and utilization of nuclear energy bring huge economic benefits and social benefits to human beings. With the wide application of nuclear energy, nuclear accidents have caused potential threats to the environment, social order and the health and safety of earth's inhabitants, so nuclear accident emergency, especially the emergency control of nuclear accident consequences, has become an essential means to ensure nuclear safety.

[0003] Nuclear pollution continuous copolymer film emergency control method has gradually become an important technical means for emergency control of nuclear accident radiation consequences due to its unique advantages of less waste, no secondary cross-contamination and high emergency efficiency. Its control operation system has become an important part of nuclear accident emergency control capability construction. The basic principle of nuclear pollution copolymer film emergency control (also known as nuclear pollution copolymer film three-stage control) is that the nuclear pollution dispersion device disperses the nuclear pollution copolymer film control agent onto the surface of the contaminated object, fully covers the nuclear pollutants, and prevents the nuclear pollutants from being suspended in the air or migrating deeply into the object under natural or artificial disturbance. At the same time, the control agent and the nuclear pollution particles interact through wetting, adsorption, embedding, adhesion, linking, micelle growth and copolymerization to form a dense nuclear decontamination copolymer film, which is completely fixed in place to control the internal radiation hazard range. The formed nuclear decontamination copolymer film is peeled off from the surface of the object and transferred to a specific place for burial, thereby eliminating the external radiation hazard of the nuclear pollution site and restoring the human survivable environment. As can be seen from the three-stage control of nuclear pollution copolymer film, the nuclear decontamination copolymer film peeling and recovery transfer is one of the inevitable actions during the nuclear accident emergency response period. In order to improve the emergency response speed and minimize the damage of the accident, the use of mechanical recovery decontamination equipment has become an inevitable tool. Therefore, a portable, self-advancing and narrow-area-use nuclear decontamination copolymer film recovery device, i.e. a portable self-advancing nuclear decontamination copolymer film recovery device, is proposed.

For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0028] Reference Figures 1 to 5 ​The utility model provides a portable self -propelled nuclear decontamination copolymer film recovery ware, including machine body trolley 1, longitudinal cutting mechanism 2 and stripping recovery mechanism 3, longitudinal cutting mechanism 2 and stripping recovery mechanism 3 are all connected on machine body trolley 1,

[0029] The recovery ware has a normal moving state and a working state, in the normal moving state, the longitudinal cutting mechanism 2 and the stripping recovery mechanism 3 are in a retracted state, and follow the machine body trolley 1 to move to a working position,

[0030] In the working state, the longitudinal cutting mechanism 2 can contact and cut the film body, and the stripping recovery mechanism 3 can contact and strip and recover the film body, and can also drive the machine body trolley 1 to move towards the film collection direction.

[0031] The recovery ware can strip and recover the nuclear decontamination copolymer film formed on the stands, aisles and other surfaces in the nuclear accident emergency, and further realize the surface decontamination and on-site environmental purification of these areas.

[0032] The recovery ware has a small volume and adjustable direction, and can be controlled by a single person, and has the functions of rapid recovery, packaging and transfer of the nuclear decontamination copolymer film on the surface of non-permeable medium and small space in a room, a car, a cave and the like.

[0033] As an optional implementation, the longitudinal cutting mechanism 2 includes a lifting guide rail 21, a vertical moving piece 22, a knurled nut 23, a transverse sliding piece 24, an auxiliary guide rail 25, a movable piece 26, a sliding block 27, a transverse guide rail 28 and a vibrating knife 29.

[0034] The bottom end of the lifting guide rail 21 is connected to the machine body trolley 1, the vertical moving piece 22 is movably connected to the lifting guide rail 21 through the knurled nut 23, the two transverse sliding pieces 24 are slidably connected to the lifting guide rail 21, each transverse sliding piece 24 is slidably connected to an auxiliary guide rail 25 and is connected to a movable piece 26, the bottom end of each auxiliary guide rail 25 is connected to a sliding block 27, each sliding block 27 is slidably connected to a transverse guide rail 28, the transverse guide rails 28 are connected to the machine body trolley 1, a compression spring 261 is arranged on the movable piece 26, the vibrating knife 29 is connected to the movable piece 26, and a cutting knife 291 is arranged on the vibrating knife 29.

[0035] The lifting guide rail 21 and the auxiliary guide rail 25 can form a vertically sliding support guide rail, so that the transverse sliding piece 24, the movable piece 26 and the vibrating knife 29 can adjust the relative position in the vertical direction, the knurled nut 23 can keep the relative position unchanged, and the knurled nut 23 can make the transverse sliding piece 24, the movable piece 26 and the vibrating knife 29 have the moving ability.

[0036] The longitudinal cutting mechanism 2 can be divided into a normal moving state and a working state, and the difference between the two states is that the height of the vibrating knife 29 and the cutting knife 291 is different;

[0037] When the longitudinal cutting mechanism 2 is in the normal moving state, the vibrating knife 29 and the cutting knife 291 are relatively located at a higher position, that is, in a lifted state, which is convenient for moving and transporting, and at this time, the bottom of the cutting knife 291 will not be in contact with the ground, preventing the cutting knife 291 from being in contact with the ground during driving and causing the cutting knife to break;

[0038] When the longitudinal cutting mechanism 2 is in the working state, the vibrating knife 29 and the cutting knife 291 are relatively located at a lower position, that is, in a lowered state, and at this time, the cutting knife 291 can be in contact with the film body to cut;

[0039] The above height is adjusted by the operator through manual adjustment of the knurled nut 23.

[0040] Since the transverse sliding member 24 is slidingly connected with the lifting guide rail 21, and the sliding block 27 is slidingly connected with the transverse guide rail 28, a support structure for transverse sliding can be formed by combination, and thus the relative distance between the two vibrating knives 29 can be adjusted in a transverse sliding manner, so that the cutting width of the film body can be adjusted, and the adjustment range can reach 0.2-0.4 m, which has a wider application range and high operation flexibility.

[0041] During the longitudinal cutting operation, the compression spring 261 cooperates with the movable piece 26 to drive the vibrating knife 29 to vibrate up and down, and the compression spring 261 can press the vibrating knife 29 to the ground, and at the same time, the vibrating knife 29 has a certain follow-up performance during operation, which can adapt to the ups and downs of the ground to fit the cutting and recovery of the co-polymer film, realize continuous recovery, effectively avoid the collision of the cutting knife, and improve the recovery efficiency.

When the stripping and recycling mechanism 3 is in the working state, the roller barrel 34 of the stripping and recycling mechanism 3 can be removed from the roller fixing hook 15 described below and lowered to contact the ground, ready to start work;

[0045] In the working state, the roller barrel 34 is removed and in contact with the co-polymer film on the ground. After the motor 31 is started, it can drive the gear and chain to rotate, thereby driving the transmission sleeve 33 and the roller barrel 34 to rotate, thereby stripping and recycling the co-polymer film on the ground. At the same time, the roller barrel 34 can be driven by the reaction force transmitted by the ground to automatically move the machine trolley 1 towards the recycling direction. The transmission mode is simple and effective, and also reduces maintenance costs.

[0046] After waiting for a roll of co-polymer film to be completely full, the connection between the transmission sleeve 33 and the roller barrel 34 can be released by the unrolling pin 35. The co-polymer film can be removed together with the roller barrel 34, and then a new roller barrel 34 can be installed to directly perform the recycling work of the next roll of co-polymer film, thereby improving efficiency.
