Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0023] Next, the working principle in the embodiment is described in detail, so that those skilled in the art can better understand the present application:

[0024] The embodiment of the present application provides a nuclear radiation sampling device, which comprises a box body 1, a cover plate 2, a transfer mechanism 4 and a detector 6. The box body 1 comprises a first accommodating cavity 101 and a second accommodating cavity 102. The cover plate 2 is installed above the first accommodating cavity 101 through the transfer mechanism 4, so as to close the first accommodating cavity 101. The detector 6 is arranged in the second accommodating cavity 102. The detection end 601 of the detector 6 is arranged in the first accommodating cavity 101. The top of the second accommodating cavity 102 is provided with a containing groove 103. A water level sensor 5 is arranged in the containing groove 103. The water level sensor 5 is electrically connected with the transfer mechanism 4. When the water level in the containing groove 103 reaches a first preset water level, the transfer mechanism 4 moves the cover plate 2, so as to release the sealing of the first accommodating cavity 101.

[0025] The detector 6 can send the detection data to the terminal of the user through a wireless network, the box body 1 is made of stainless steel, the durability in the open field is increased, the box body 1 collects rainwater through the first accommodating cavity 101, and the second accommodating cavity 102 is provided with the detector 6 and the like. When it does not rain, the first accommodating cavity 101 can be sealed through the cover plate 2 to avoid impurities such as dust from entering to pollute the sample, and the accuracy of detection is improved. When it rains, the water level in the containing groove 103 rises, a signal is transmitted to the transfer mechanism 4 through the water level sensor, and then the cover plate 2 controls the opening and closing of the first cavity, wherein the rainwater that falls at the beginning has a high pollutant composition, and using the rainwater as a detection sample will make the detection data high, and because it takes a certain time for the rainwater to reach the first preset water level, after the cover moves, the pollutants in the rainwater entering the first accommodating cavity 101 are at an average level, and using the rainwater as a sample for detection is more accurate. In the embodiment, the cover plate 2 can be a solar panel, which can seal the first accommodating cavity 101 when it does not rain, and can also store electric energy for the detector 6 and the like. It should be noted that the solar panel can be installed on the cover plate 2, or the solar panel can be directly used as the cover plate 2, which can be adjusted according to the use environment. In one implementation, the transfer mechanism 4 includes a gear 402, a rack 401 and a motor, the rack 401 is installed on the back of the cover plate 2, the motor is arranged in the second accommodating cavity 102 and connected with the gear 402, and the gear 402 and the rack 401 are meshed with each other. The motor is electrically connected with the solar panel to drive the cover plate 2, the cooperation of the gear 402 and the rack 401 can make the cover plate 2 move horizontally to simplify the structure, and the horizontal movement can reduce the stress area of the nuclear radiation sampling device in the embodiment and improve the durability. It should be noted that the moving direction of the cover plate 2 can be set according to the actual situation.

[0027] The accommodating groove 103 is in a rectangular structure, and rainwater can be discharged through the second water outlet 1031 after the rainwater is collected. Moreover, the area of the second water outlet 1031 is smaller than the area of the accommodating groove 103, that is, when the rainfall reaches a set amount, the water level in the accommodating groove 103 can reach the first preset water level, so that the influence of too little rainfall on the low content of pollutants in rainwater can be reduced. Similarly, the rainwater in the first accommodating cavity 101 is discharged through a valve, so as to avoid that dust and other impurities in the air are left in the first accommodating cavity 101. In an implementation manner, the valve is a float ball valve 1011, and when the water level in the first accommodating cavity 101 reaches a second preset water level, the float ball valve 1011 discharges the water in the first accommodating cavity 101.
