Description

Technical Field

[0001] This utility model patent belongs to the technical field of generator auxiliary equipment, specifically relating to a rinsing box for shielding the radioactivity of a generator. Background Technology

[0002] The demand for molybdenum technetium generators has surged, leading to increased radiation doses due to higher overall activity. Existing washing cabinets lack independent shielding for individual generators, resulting in poor shielding. During daily production, washing one generator exposes the operator to cumulative radiation from the others, exposing them to additional radiation and causing radiation leaks in the washing and labeling / packaging areas, seriously threatening personnel safety and the production environment. Furthermore, the entrances to existing washing cabinets are too high, requiring the operator to lift the cabinet with both hands to place new generators in and retrieve old ones, making it extremely inconvenient and resulting in unnecessary additional radiation exposure. Therefore, an upgrade to the washing cabinets is urgently needed.

[0003] To address the aforementioned problems, this invention proposes a rinsing box for shielding the radioactivity of a generator. Utility Model Content

[0004] To address the aforementioned issues, this invention provides a rinsing tank for shielding the radioactivity of generators. The operating window provides radiation shielding for operators when storing generators. The cylindrical tank ensures that each generator has an independent operating space and independent shielding function. It also allows for the control of raising and suspending the bottom of the tank individually or in groups, and for a buffered descent. While ensuring that each generator has an independent operating space and independent shielding function, it also facilitates the removal of all generators together by operators in emergencies. Furthermore, because each generator has an independent operating space and independent shielding function, and is equipped with a radiation-shielding operating window, in emergencies, the generators in the cylindrical tank can be raised and rinsed directly inside the tank.

[0005] To achieve the above-mentioned technical effects, this utility model is implemented through the following technical solution: a rinsing box for shielding the radioactivity of a generator, comprising a box body and casters. The box body further includes an operating table that can load, unload, and rinse new and old generators while shielding radiation, a radiation-shielding storage layer, and a lifting mechanism that can control the bottom of the storage layer to be raised and lowered individually or in multiple groups.

A piston is movably installed in the lifting cylinder, and a lifting rod is connected to the upper surface of the piston, with the top of the lifting rod connected to the chassis. Several sets of type 7 slots are evenly arranged on the front and rear sides of the lifting rod. A lifting plate is provided above the lifting cylinder, and the lifting plate is mounted on spring supports on the left and right sides of the housing through ear plates. A limiting mechanism corresponding to the type 7 slot is installed on the lifting plate, and a foot-operated rocker lifting mechanism is installed on the bottom of the housing below the lifting plate.

[0012] Preferably, the limiting mechanism further includes a limiting hole, a retaining seat, a gear, a limiting clip, a hinge, a torsion spring, a rack, a pull rod, a limiting seat, and a pull rod groove. The limiting hole is located where the lifting plate is penetrated by the lifting rod. A retaining seat is rotatably mounted on the limiting hole. A gear is provided on the side of the retaining seat. A limiting clip is mounted on the upper surface of the retaining seat via a hinge, and a torsion spring is installed in the hinge. The torsion spring can spring the limiting clip toward the center of the limiting hole. A rack is meshed next to the gear. A pull rod is mounted on the rack, and the end of the pull rod extends out of the housing through a pull rod groove on the housing.

[0015] The beneficial effects of this utility model are:

[0016] The operating window in this invention can shield operators from radiation when storing the generator, and can be moved left and right to accommodate operator use. The cylindrical container ensures that each generator has an independent operating space and independent shielding function, which greatly reduces the radiation dose. The cylindrical container can be made of high-quality shielding materials such as 12ppb lead alloy, which effectively blocks radiation. This design can also prevent the accumulation of radiation dose at the source, comprehensively protecting the safety of production operators and the workshop environment. The handle in the cylindrical container makes it easy to open and close the lid, and the pressure plate can be used to tighten the lid. The chassis that can slide up and down along the inside of the cylindrical container makes it easy to raise and lower the generator. The rubber pad under the chassis can prevent radiation from leaking from below when the chassis is raised or lowered, protecting the safety of production operators and the workshop environment.

[0017] When it is necessary to store or retrieve the generator, the bucket lid can be opened, and the cylindrical base can be quickly raised by the rapid lifting mechanism, making it easy for operators to quickly store or retrieve the generator. Then, the base can be slowly lowered by the return buffer mechanism, and the bucket lid can be closed, thus achieving quick retrieval and slow placement, thereby improving work efficiency. In addition, this structure can also control the bottom of the cylindrical base to be raised and suspended individually or in multiple groups and to fall back with a buffer. While ensuring that each generator has an independent operating space and independent shielding function, it also makes it easy for operators to retrieve all generators at once in an emergency. Furthermore, because each generator has an independent operating space and independent shielding function, and is equipped with a radiation-shielding operating window, in an emergency, the generator in the cylindrical base can be raised and rinsed directly in the cylindrical base.

[0018] When the chassis needs to be lowered, the operator can gently lift the foot plate with the instep to allow the vent pin on the base plate to pierce the one-way valve vent and release the air. To ensure the chassis lowers slowly, the operator can control the force applied by lifting the foot. At the same time, the small spring can both reset the base plate and allow the operator to better feel the force applied by lifting the foot. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Example 1

[0031] like Figures 1 to 8 As shown, the existing technology in this embodiment has the following problems: The inventors found that the existing washing cabinet lacks an independent shielding function for each generator, and the shielding effect is poor. During daily production, when washing one generator, the operator will be exposed to the superimposed radiation damage from the other generators. This not only exposes the operator to additional radiation, but also causes radiation leakage in the washing room and the marking and packaging room, which seriously threatens personnel safety and the production environment. Secondly, the entrance of the existing washing cabinet is too high. Every time a new generator is put into storage or an old generator is recycled, it is necessary to lift it with both hands to put it in and take it out of the cabinet, which is extremely inconvenient to use and will also cause additional unnecessary radiation. Therefore, it is urgent to upgrade and transform the washing cabinet.

[0032] Therefore, the inventor provides a rinsing box for shielding the radiation of a generator, including a box body 1 and casters 2. The box body 1 also includes an operating table 3 that can load, unload and rinse new and old generators while shielding radiation, a radiation-shielding storage layer, and a lifting mechanism that can control the bottom of the storage layer to be raised and lowered individually or in multiple groups. An operating window that can slide left and right and shields radiation is slidably installed in the slide rail 6 on the front side of the operating table 3. The storage layer is provided with several radiation-shielding cylinders 7. The bottom of each cylinder 7 can be detachably installed with a lifting mechanism, and the lifting mechanism can control the bottom of the cylinder 7 to be raised and suspended individually or in multiple groups and lowered with a buffer.

[0033] Its effects are as follows: the operating window in this utility model can shield the operator from radiation when storing the generator, and can be moved left and right to facilitate the operator's use; the cylinder 7 can ensure that each generator has an independent operating space and independent shielding function, which will greatly reduce the radiation dose. The cylinder 7 can be made of high-quality shielding materials such as 12ppb lead alloy, which can effectively block radiation. Moreover, this design can prevent the accumulation of radiation dose from the source and fully protect the safety of production operators and the workshop environment.

[0034] When it is necessary to store or retrieve the generator, the lid 8 can be opened, and the base 11 of the cylindrical tank 7 can be quickly raised by the rapid lifting mechanism, so that the operator can quickly store or retrieve the generator. Then, the base 11 can be slowly lowered by the return buffer mechanism, and the lid 8 can be closed, thus realizing quick retrieval and slow placement, thereby improving work efficiency. In addition, this structure can also control the bottom of the cylindrical tank 7 to lift and hover individually or in multiple groups and to fall back with a buffer. While ensuring that each generator has an independent operating space and independent shielding function, it also makes it easy for the operator to retrieve all the generators at once in an emergency. Furthermore, because each generator has an independent operating space and independent shielding function, and is equipped with an operating window that can shield radiation, in an emergency, the generator in the cylindrical tank 7 can be lifted and rinsed directly in the cylindrical tank 7.

[0035] When the chassis 11 needs to be lowered, the operator can gently lift the foot plate 40 with the instep of their foot so that the air release nail 41 on the base plate 39 can be inserted into the air nozzle of the one-way valve 17 to release the air. If the chassis 11 needs to be lowered slowly, the force of the foot can be controlled. At the same time, the small spring 43 can not only reset the base plate 39, but also allow the operator to better feel the force of lifting the foot.

[0036] Furthermore, the operating window also includes a window frame 4 made of lead alloy and lead glass 5. The base of the window frame 4 is slidably mounted on the front slide rail 6 of the operating table 3, and the upper part of the window frame 4 is fitted with lead glass 5 facing the top of the cylinder 7.

[0037] Its effects and principles: This structure can shield the operator from radiation when storing the generator, and the operating window can be moved left and right to accommodate the operator's use.

[0038] Furthermore, the storage layer is equipped with six lead alloy cylinders 7 that can shield radiation;

[0039] Its effects and principles: This structure can ensure that each generator has an independent operating space and independent shielding function, which will greatly reduce the radiation dose. The material of the cylinder 7 can be made of high-quality shielding materials such as 12ppb lead alloy, which can effectively block radiation. Moreover, this design can prevent the accumulation of radiation dose from the source and fully protect the safety of production operators and workshop environment.

[0040] Furthermore, a lid 8 is installed on the top of the barrel 7, a folding handle 9 is installed on the center of the upper side of the lid 8, a pressure plate 10 is installed on the operating table on the edge of the lid 8, and a base 11 that can slide up and down along the inner side of the barrel 7 is installed at the bottom of the barrel 7.

[0041] Its effects and principles: The handle in this structure makes it easy to open and close the barrel lid 8, the pressure plate 10 can be used to press the barrel lid 8, and the base 11, which can slide up and down along the inner side of the barrel 7, can facilitate the raising and lowering of the generator.

[0042] Furthermore, a radiation-proof polymer pad 12 is provided on the mounting surface of the chassis 11 and the bottom of the barrel 7.

[0043] Its effect and principle: This structure can prevent radiation from leaking from below when the chassis is raised or lowered, thus protecting the safety of production operators and the workshop environment.

[0044] Furthermore, the lifting mechanism also includes a foot-operated rapid lifting mechanism and a foot-operated return buffer mechanism. The rapid lifting mechanism is installed at the bottom of the housing 1 below the chassis 11 and its top is connected to the bottom surface of the chassis 11. The return buffer mechanism is installed at the bottom of the housing 1.

[0045] Its effects and principles: When storing or waiting to retrieve the generator, the structure allows the lid 8 to be opened, and the base 11 of the cylindrical barrel 7 to be quickly raised via a rapid lifting mechanism, making it easy for operators to quickly store or retrieve the generator. Then, the base 11 is slowly lowered via a return buffer mechanism, and the lid 8 is closed, thus achieving fast retrieval and slow placement, thereby improving work efficiency. Furthermore, the structure can control the bottom of the cylindrical barrel 7 to be raised and suspended individually or in multiple groups, and to fall back with a buffer. While ensuring that each generator has an independent operating space and independent shielding function, it also makes it easy for operators to retrieve all generators at once in an emergency. Moreover, because each generator has an independent operating space and independent shielding function, and is equipped with a radiation-shielding operating window, in an emergency, the generator in the cylindrical barrel 7 can be raised and rinsed directly in the cylindrical barrel 7.

[0046] Furthermore, the rapid lifting mechanism also includes a lifting cylinder 13, a lifting rod 14, a type 7 slot 15, a piston 16, a one-way valve 17, a lifting plate 18, an ear plate 19, a spring support 20, a limiting mechanism, and a foot-operated rocker lifting mechanism. The lifting cylinder 13 is mounted on the chassis 11. A one-way valve 17 is provided at the bottom of the lifting cylinder 13. A piston 16 is movably installed in the lifting cylinder 13. A lifting rod 14 is connected to the upper surface of the piston 16, and the top of the lifting rod 14 is connected to the chassis 11. Several sets of type 7 slots 15 are evenly arranged on the front and rear sides of the lifting rod 14. A lifting plate 18 is provided above the lifting cylinder 13, and the lifting plate 18 is mounted on the spring supports 20 on the left and right sides of the housing 1 through the ear plate 19 on it. A limiting mechanism corresponding to the type 7 slot 15 is installed on the lifting plate 18. A foot-operated rocker lifting mechanism is installed on the bottom of the housing 1 below the lifting plate 18.

[0047] Its effect and principle: When using this structure, if it is necessary to lift the chassis 11, the operator adjusts the limiting mechanism corresponding to the cylinder 7 to be operated to align with the 7-type slot 15, and then operates the foot-operated rocker lifting mechanism to lift the lifting rod 14. During the lifting process, the piston 16 can pressurize the lifting cylinder 13 through the one-way valve 17. When the pedal 34 in the foot-operated rocker lifting mechanism is stepped to the bottom of the box 1, the pedal 34 can be released, and the spring support 20 pulls down the lifting plate 18 and lifts the pedal 34, and the limiting mechanism is locked down to the next level 7-type slot 15 on the lifting rod 14. During this process, the gas in the lifting cylinder 13 will prevent the lifting rod 14 from flowing back. This can be repeated to continuously lift the chassis 11.

[0048] Furthermore, the limiting mechanism also includes a limiting hole 21, a card seat 22, a gear 23, a limiting card 24, a hinge 25, a torsion spring 26, a rack 27, a pull rod 28, a limiting seat 29, and a pull rod groove 30. The limiting hole 21 is located where the lifting plate 18 is penetrated by the lifting rod 14. A card seat 22 is rotatably mounted on the limiting hole 21. A gear 23 is provided on the side of the card seat 22. A limiting card 24 is mounted on the upper surface of the card seat 22 through a hinge 25, and a torsion spring 26 is installed in the hinge 25. The torsion spring 26 can spring the limiting card 24 toward the center of the limiting hole 21. A rack 27 is meshed next to the gear 23. A pull rod 28 is mounted on the rack 27, and the end of the pull rod 28 extends out of the housing 1 through the pull rod groove 30 on the housing 1. A limiting seat 29 is provided on the pull rod 28 at the front end of the rack 27 to limit the travel of the rack 27.

[0049] Its effect and principle: When using this structure, if it is necessary to lift the chassis 11, push the pull rod 28 to make the rack 27 drive the gear 23 to rotate, which in turn makes the card seat 22 drive the limit card 24 to rotate, and rotate the limit card 24 into the 7-type card slot 15. In this way, the lifting rod 14 can be lifted under the action of the lifting plate 18. When the lifting plate 18 is resetting downward, the torsion spring 26 can also keep the limit card 24 tightly attached to the lifting rod 14, so as to ensure that the limit card 24 can be locked into the next level 7-type card slot 15 on the lifting rod 14 again, so as to continue to lift. Similarly, if the lifting rod 14 is to be lowered, the limit card 24 must first be rotated to the left and right sides of the lifting rod 14 where there are no card slots.

[0050] Furthermore, the foot-operated rocker lifting mechanism also includes a base 31, a rocker arm 32, a rocker arm groove 33, a pedal 34, a connecting rod 35, a connecting rod groove 36, a lifting plate 37, and a limiting ball head 38. The base 31 is mounted on the base of the housing 1. The middle part of the rocker arm 32 is rotatably mounted on a shaft in the base 31 through a shaft hole. The front end of the rocker arm 32 extends out of the housing 1 from the rocker arm groove 33 and is provided with a pedal 34 at the front end. The rear end of the rocker arm 32 is connected to the lower end of the connecting rod 35 through a rotating joint. The upper end of the connecting rod 35 is mounted in the connecting rod groove 36 in the lifting plate 18 and the top end of the connecting rod 35 is connected to the limiting ball head 38.

[0051] Its effect and principle: When using this structure, if the chassis 11 needs to be raised, simply step on the pedal 34. Under the transmission of the base 31, the connecting rod 35 is lifted by the rocker arm 32. The lifting plate 18 is lifted by the lifting plate 37 on the connecting rod 35, thereby lifting the chassis 11. Because the rocker arm 32 moves upward in an arc, the connecting rod groove 36 can accommodate a small horizontal displacement of the connecting rod 35, while the limiting ball head 38 can prevent the connecting rod 35 from having a serious horizontal displacement.

[0052] Furthermore, the foot-lifting drop buffer mechanism also includes a base plate 39, a foot-lifting plate 40, an air release pin 41, a limiting post 42, and a small spring 43. The base plate 39 is movably installed on the outer side below the bottom of the box via the limiting post 42. The foot-lifting plate 40 is provided in front of the base plate 39. The upper surface of the base plate 39 is provided with an air release pin 41 corresponding to the air nozzle of the one-way valve 17. The upper part of the limiting post 42 extends into the inner side of the bottom of the box. The small spring 43 is sleeved on the upper end of the limiting post 42, and the upper and lower ends of the small spring 43 are respectively connected to the top of the limiting post 42 and the bottom of the box.

[0053] Its effect and principle: When using this structure, the operator can gently lift the foot plate 40 with the instep of their foot, so that the air release nail 41 on the base plate 39 can be inserted into the air nozzle of the one-way valve 17 to release the air. If it is necessary to ensure that the chassis 11 descends slowly, the force of the foot can be controlled. At the same time, the small spring 43 can not only reset the base plate 39, but also allow the operator to better feel the force of lifting the foot.
