Alternative embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 4, the present invention provides a radiation-proof living animal storage 100 configured to store living animals having radionuclides in the body, such as rats and/or mice, and living animals injected with radionuclides or contaminated with radionuclides need to be stored in the radiation-proof living animal storage 100. The living animal storing tank 100 includes a tank body 10, a light-transmitting window 20, and a fluorescent lamp 30.
The cabinet 10 is made of a radiation-proof material, for example, the cabinet 10 may be made of a lead plate coated with stainless steel. The cabinet 10 has a receiving space 40 therein, and the receiving space 40 is configured to receive a feeding box for receiving living animal examples, such as rats and/or mice, injected with radionuclides or subjected to radioactive contamination.
The light-transmitting window 20 is disposed on the top wall of the cabinet 10, and is configured to allow external natural light to be incident into the cabinet 10 to provide a light environment, and the light-transmitting window 20 is made of lead glass with radiation protection function, for example, and has good light transmittance, and meanwhile, can prevent radiation generated by living animals injected with radionuclides or suffering from radioactive pollution from leaking out of the cabinet 10 after the living animals are loaded into the cabinet 10.
The fluorescent lamp 30 is disposed on an inner sidewall of the cabinet 10, and is configured to automatically adjust brightness to supplement natural light incident into the cabinet, so that the light environment in the cabinet changes with time to simulate the external natural light environment. Namely, a natural light environment is simulated in the accommodating space 40 inside the cabinet body 10 through the light-transmitting window 20 and matched with the fluorescent lamp 30, and particularly, the natural light environment accords with the natural light environment of a specific living animal. The living animal stored in the cabinet 10 is prevented from being physiologically or psychologically affected due to an uncomfortable light environment. The intensity, chromaticity and the like of the fluorescent lamp 30 can be automatically adjusted, so that the light environment constructed by arranging the light transmission window 20 and matching with the fluorescent lamp 30 can be automatically adjusted at any time, thereby simulating the simulated natural light environment which is basically the same as the external natural light. The simulated natural light environment also distinguishes, for example, between daytime and nighttime, etc., and provides simulated natural light of different light intensities at different time periods. The fluorescent lamp 30 is, for example, an LED lamp that emits white light, and can simulate the effect of natural light.
In the embodiment of the invention, the radiation-proof living animal storage cabinet can be used for storing living animals which are fed with radionuclides or are polluted by radioactivity to avoid polluting operators or environment, external natural light can be allowed to enter the cabinet body through the light transmission window to provide a light environment, and meanwhile, the natural light entering the cabinet body is supplemented by the fluorescent lamp capable of automatically adjusting the brightness in the cabinet body, so that the light environment in the cabinet body changes along with time to simulate the external natural light environment.
In some embodiments, as shown in fig. 1 to 4, the top wall of the living animal storage cabinet 100 is further provided with an air inlet 51, so that the external clean air enters the cabinet 10, and the bottom wall of the living animal storage cabinet 100 is further provided with an air outlet, so that the dirty air in the cabinet 10 is discharged out of the cabinet, and the air in the cabinet 10 flows from top to bottom, so as to ensure that the interior of the cabinet 10 is suitable for the living animal air environment. By providing the air inlet 51 and the air outlet 52 on the top wall and the bottom wall of the living animal storage cabinet 100, respectively, the dirty air generated by the living animal in the cabinet 10 can be exchanged with the clean air outside, so that the inside of the cabinet 10 is always suitable for the living animal air environment.
In other embodiments, the air intake apertures may also be provided in the side walls, for example at a location where the side walls are adjacent the top wall, to increase the air intake path of the cabinet.
Since the feeding boxes for storing living animals provided in the cabinet 10 are generally open at the top, the upward and downward gas flow formed in the cabinet 10 more easily allows clean air to enter each feeding box to replace the dirty gas therein.
The living animal storing compartment 100 further includes a blocking member 60 provided at the air intake hole 51 and/or the air exhaust hole 52, configured to prevent radiation in the compartment from leaking out of the compartment through the air intake hole 51 and/or the air exhaust hole 52. I.e. to avoid leakage of radiation generated by the living animal injected with radionuclides or subjected to radioactive contamination, through the air inlet holes 51 and/or the air outlet holes 52 after it has been loaded into the cabinet 10.
In some embodiments, a filter screen is disposed in the air inlet 51, so that only clean air from outside is allowed to enter the cabinet 10 through the air inlet 51, and foreign matters, such as foreign matters, dust particles, etc., are filtered to enter the cabinet 10.
In some embodiments, an exhaust fan 521 is disposed in the exhaust port 52, and the exhaust fan 521 rotates to rapidly exhaust the dirty air in the cabinet 10 through the exhaust port 52. In some embodiments, the exhaust port 52 may also be connected to an exhaust device, which may provide power to allow the dirty air within the cabinet 10 to be quickly exhausted through the exhaust port 52.
In some embodiments, as shown in fig. 1 to 4, the blocking member 60 is disposed on an inner wall of the cabinet 10, the blocking member 60 is spaced apart from its corresponding air inlet hole 51 or air outlet 52 by a predetermined distance, and an orthographic projection of the blocking member 60 on the inner wall covers its corresponding air inlet hole 51 or air outlet 52. Because the radiation generally propagates in a straight line, the blocking member 60 can block the radiation from propagating through the air inlet 51 or the air outlet 52 to the outside of the cabinet 10, and the blocking member 60 is also made of radiation-proof material. The blocking member 60 corresponding to the intake hole 51 is shown in fig. 3, and the blocking member 60 corresponding to the exhaust hole 52 is not shown in fig. 4 in order to embody the specific structure of the exhaust hole 52, and the structure thereof may refer to the blocking member 60 shown in fig. 3.
The following will mainly explain the blocking member 60 corresponding to the air intake hole 51. As shown in fig. 1 to 4, in some embodiments, as shown in fig. 1 to 3, the number of air inlets 51 on the top wall of the living animal storage cabinet 100 is plural, and the number of corresponding stoppers 60 is plural, and the air inlets 51 are in one-to-one correspondence with the stoppers 60. As shown in fig. 2, on the top wall of the living animal storing cabinet 100, two rows of air intake holes 51 are provided on both sides of the light-transmitting window 20, respectively.
The diameter of the air inlet hole 51 is, for example, less than or equal to 6cm, the area of the air inlet hole 51 is less than the area of the corresponding blocking piece 60, and the area of the blocking piece 60 is, for example, more than 2 times, for example, 4 times, the area of the air inlet hole 51. The distance between the blocking piece 60 and the corresponding air inlet hole 51 is, for example, less than 4cm, for example, 2cm, and by adjusting the area between the blocking piece 60 and the corresponding air inlet hole 51 and the distance between them, the size of the air inlet hole 51 is as large as possible to ensure that sufficient external clean air can enter the cabinet 10 through the air inlet hole 51 and ensure the air environment in the cabinet 10 under the condition that the blocking piece 60 blocks the radiation of the radiation source positioned in the cabinet 10 from leaking through the air inlet hole 51. In other embodiments, one blocking member 60 may also correspond to a plurality of air intake holes 51 at the same time, i.e., the front projection of one blocking member 60 on the inner wall of the top wall may cover a plurality of air intake holes 51.
In some embodiments, the orthographic projection of the air intake aperture 51 onto the baffle 60 is located at the center of the baffle 60. By this arrangement, the blocking member 60 can better block radiation from propagating through the air inlet hole 51 to the outside of the cabinet 10.
In some embodiments, as shown in fig. 3, the blocking member 60 is disposed in parallel spaced relation to the top wall of the living animal holding cabinet, and the blocking member 60 is secured to the inner wall of the top wall of the living animal holding cabinet by a connector. Specifically, the periphery of the blocking member 60 is uniformly provided with a plurality of connection members, and the plurality of connection members fix the blocking member 60 on the inner wall of the top wall such that the blocking member 60 has a predetermined distance from its corresponding air inlet hole 51.
In some embodiments, the structure and function of the barrier of the corresponding exhaust port 52 provided on the bottom wall of the living animal holding cabinet 100 is substantially the same as the structure and function of the barrier of the corresponding exhaust port 52. The diameter of the exhaust port 52 is, for example, 4cm or more and 10cm or less, the area of the exhaust port 52 is smaller than the area of the corresponding barrier 60, and the area of the barrier 60 is, for example, 2 times or more, for example, 4 times the area of the exhaust port 52. The distance between the blocking member 60 and the corresponding air outlet 52 is, for example, less than 4cm, for example, 2cm, and by adjusting the area between the blocking member 60 and the corresponding air outlet 52 and the distance between them, the size of the air outlet 52 is as large as possible to ensure that the dirty air can be discharged out of the cabinet 10 through the air outlet 52 and the air environment in the cabinet 10 can be ensured under the condition that the blocking member 60 blocks the radiation of the radiation source located in the cabinet 10 from leaking through the air outlet 52. In some embodiments, the number of exhaust ports 52 is 1 or more, for example 2.
In some embodiments, the orthographic projection of the exhaust port 52 onto its corresponding barrier 60 is located at the center of the barrier 60. This arrangement allows the barrier 60 to better block radiation from traveling out of the cabinet 10 through the exhaust port 52.
In some embodiments, the blocking member 60 corresponding to the air outlet 52 is disposed in parallel with and spaced apart from the bottom wall of the living animal holding cabinet, and the blocking member 60 is fixed to the inner wall of the bottom wall of the living animal holding cabinet by a connecting member. Specifically, the periphery of the blocking member 60 is uniformly provided with a plurality of connection members, and the plurality of connection members fix the blocking member 60 on the inner wall of the bottom wall such that the blocking member 60 has a predetermined distance from its corresponding exhaust port 52.
In some embodiments, as shown in fig. 1 to 4, the living animal storage cabinet 100 includes a partition 70, and the partition 70 partitions the accommodating space 40 into a plurality of sub-accommodating spaces in a vertical direction, each of the sub-accommodating spaces being configured to accommodate the feeding bin. Each of the spacers 70 includes a plurality of parallel spaced bars, which are disposed to facilitate the flow of the other sub-spaces from top to bottom. The compartment 70 may support a feeding tank placed thereon.
In some embodiments, the number of the fluorescent lamps 30 is multiple, and each fluorescent lamp 30 is disposed in one of the sub-accommodation spaces. Each group of fluorescent lamps 30 independently and automatically adjusts brightness, supplements natural light incident into the corresponding sub-accommodation space, and enables the light environment in the corresponding sub-accommodation space to change along with time so as to simulate the external natural light environment. Because the positions of the plurality of sub-accommodating spaces arranged from top to bottom are different, the illumination and distribution of the light received by the sub-accommodating spaces from the light-transmitting window are also different. In order to make each sub-accommodation space simulate the light environment close to the external natural light environment, each group of fluorescent lamps 30 corresponding to each sub-accommodation space needs to be automatically regulated and controlled to different degrees.
In some embodiments, as shown in fig. 1-4, the cabinet 10 includes: a cabinet body 11, a cabinet door 12 and a hydraulic connecting rod 13. The cabinet body 11 has an opening exposing the receiving space 40. A cabinet door 12 is pivotally connected to the cabinet body 11 and is configured to close the opening in a closed state. By opening the cabinet door 12, the transfer of the mobile animal or its feeding box between the inside and the outside of the cabinet can be achieved. The hydraulic link 13 is disposed at the cabinet body 11 and connects the cabinet door 12 such that the cabinet door 12 has a tendency to be in a closed state.
