Description

Technical Field

[0001] The utility model relates to the technical field of radioactive pollutant removal devices, in particular to a handheld radioactive pollutant removal device. Background Art

[0002] In the places where nuclear materials are mined, transported, processed, stored and nuclear waste is disposed of, there are large amounts of radioactive dust to varying degrees. If appropriate measures are not taken in time to deal with these tiny radioactive dusts, they will remain in the indoor environment for a long time and be contaminated to other environments through human activities, causing the expansion of the pollution area and increasing the difficulty of subsequent disposal.

[0003] At present, for radioactive fallout pollution in indoor environments, decontamination is generally carried out by using peelable film pressing decontamination method, air replacement or high-efficiency filtration method: First, the peelable film pressing decontamination method mainly uses a large spraying vehicle or a hand-push sprayer to spray the pressing decontaminant on a large area into the contaminated area, pressing and fixing the radioactive particles in the air and on the ground to form a peelable film body that embeds the radioactive particles, and finally peeling and curling the film body and transporting it away from the site, so as to achieve the purpose of removal. This method is suitable for handling large-scale radioactive pollution, but the disposal time is long and it is not suitable for handling radioactive contamination in daily work; second, the air replacement method or high-efficiency filtration method, which often needs to be applied to large-scale ventilation equipment and filtering equipment, is not only easy to produce dead angles in operation, but also cannot remove radioactive dust adsorbed on the surface of the building;

[0004] In order to solve the above technical problems, the current common practice is to use the vacuum method to adhere and remove the radioactive fallout contamination on the surface of the building. The specific implementation method is to use a decontamination film bound to the outside of the drum to adhere to the radioactive fallout and remove the radioactive fallout on the surface of the building; however, the decontamination film needs to be replaced manually after use, which greatly increases the risk of radioactive contamination and greatly reduces the removal efficiency.

[0005] Therefore, how to design a handheld radioactive contaminant removal device with a simple structure, easy use, high removal efficiency, good removal effect and the ability to automatically replace the decontamination film is an urgent problem that technicians in this field need to solve. Utility Model Content

[0006] The utility model provides a handheld radioactive pollutant removal device, which solves the technical problems of low removal efficiency, poor removal effect and high risk of personnel contamination (manual replacement of adhesive film) in existing radioactive fallout pollutant removal devices.

[0007] The utility model solves the above technical problems with the following technical solutions: a handheld radioactive pollutant removal device, comprising: an operating component, a decontamination roller and an automatic membrane replacement mechanism,

[0008] The operating component includes a hand-held rod, a fixed bracket and a connecting shaft, and the fixed bracket is fixed to the bottom end of the hand-held rod; the connecting shaft is arranged vertically with the hand-held rod and is rotatably connected to the fixed bracket; a closing plate is fixed to an open end of the decontamination roller and a fixing hole is provided in the middle of the closing plate, and the outer peripheral side wall of the decontamination roller is provided with a long strip hole arranged along its axial direction; the connecting shaft is penetrated and fixed in the fixing hole; the automatic film changing mechanism includes a motor, an old film cylinder and a new film cylinder wrapped with a decontamination film, the motor is fixed on the closing plate and its output shaft is arranged along the axis of the decontamination roller; the old film cylinder and the new film cylinder are arranged in the decontamination roller at intervals along the axis of the decontamination roller, one end of the old film cylinder is rotatably connected to the closing plate, and one end of the new film cylinder is fixed to the motor; the free end of the decontamination film passes through the long strip hole as the new film cylinder rotates, bypasses the decontamination roller, penetrates into the long strip hole and is fixed to the outer peripheral side end of the old film cylinder.

[0009] The beneficial effects of the utility model are: changing the traditional radioactive pollutant removal method, using a motor to drive the new film cylinder to rotate, because the free end of the decontamination film passes through the long hole, bypasses the decontamination roller, and passes through the long hole to be fixed on the outer peripheral side of the old film cylinder, the decontamination film can be automatically replaced after the decontamination film is adhered to and removes the radioactive fallout contamination, thereby reducing manual intervention and manual contact, reducing the risk of personnel being contaminated, and avoiding the secondary use of the decontamination film, thereby improving the removal efficiency and removal effect of radioactive fallout. Based on the above technical solution, the utility model can also be improved as follows.

[0010] Furthermore, the handheld rod includes a first rod section, an electric telescopic rod section and a second rod section which are integrally connected; and the fixed bracket is fixed to the bottom end of the second rod section.

[0011] A further beneficial effect of the above method is that the length of the hand-held rod can be changed by extending or contracting the electric telescopic rod section to adapt to clearing radioactive fallout in different locations.

[0012] Furthermore, the fixed bracket includes a first plate and a second plate that are integrally formed and vertically arranged, the first plate is arranged perpendicularly to the handle bar and fixed to the bottom end of the handle bar; the connecting shaft is arranged perpendicularly to the second plate and one end of the connecting shaft is rotatably connected to the plate surface of the second plate.

[0013] Furthermore, it also includes a drum cover, which is detachably buckled on the other open end of the decontamination drum.

[0014] A further beneficial effect of the above method is that the drum cover can be detachably fastened to the other open end of the decontamination drum, so that the decontamination film can be easily replaced.

[0015] Furthermore, it also includes a limiting plate, which is located on one side of the other end of the decontamination drum and is detachably connected to the fixing bracket.

[0016] A further beneficial effect of the above method is that a limit plate is placed on one side of the other end of the cleaning drum to prevent the cleaning drum from falling abnormally during rolling.

[0017] Furthermore, the controller is fixed on the hand-held rod and is wirelessly connected to the motor via Bluetooth or WiFi.

[0018] The above further beneficial effect is: utilizing the wireless communication connection between the controller and the motor can facilitate the use by the operator, automatically replace the decontamination film, and also avoid the secondary use of the decontamination film, thereby improving the cleaning efficiency and cleaning effect of the decontamination film.

[0019] Furthermore, the decontamination film is a paper film with stickiness on one side.

[0020] Furthermore, the outer peripheral side end of the decontamination roller is made of soft material.

[0021] The further beneficial effect of adopting the above method is that the outer peripheral side end of the cleaning drum is made of soft material, and the uneven surface of the building can be cleaned under the pushing state of the hand-held rod. BRIEF DESCRIPTION OF THE DRAWINGS
