Description

Technical Field

[0001] This utility model relates to the field of liquid contamination detection technology, and in particular to a portable liquid contamination sampling and detection device for nuclear decontamination cabins. Background Technology

[0002] The portable liquid contamination sampling and detection device for nuclear decontamination cabins is mainly used in scenarios such as nuclear facility accident leaks, radioactive material transportation accidents, and post-disaster rescue in nuclear contaminated areas. Its core function is to quickly collect contaminated liquid samples on-site and analyze the radioactive nuclides in the samples in real time. It can be used in conjunction with nuclear decontamination cabins.

[0003] Traditional portable liquid contamination sampling and detection devices in nuclear decontamination shelters consist of four basic parts: a manual liquid extraction component, a sample storage bottle, an independent radioactive detection module, and a portable storage box. Manual liquid extraction relies on the operator's physical strength, and protective gloves significantly reduce hand dexterity. This not only results in low extraction efficiency but also leads to sample volume deviations due to uneven pressure, and even sample spillage. Sampling and detection are performed in separate steps, making them susceptible to cross-contamination by external air pollutants, dust, or other radioactive substances, which can distort the detection data. The detection module is cumbersome to operate, requiring manual calibration of the detection position and detection time, and cannot meet the rapid detection needs in nuclear emergency scenarios.

[0004] Existing technologies improve upon this in two ways: replacing manual piston pumps with electric micro-pumps, enabling automatic pumping via button control, reducing operational steps, and integrating the electric pump, sample storage unit, and radioactivity detection module into a portable case to form an integrated sampling and detection structure. The pump draws samples into the integrated sample chamber via a silicone tube. However, the problem of the electric pumping equipment being unable to be quickly replaced becomes apparent. The pump is fixed to the bracket inside the case with screws, and the tubing is threaded and sealed to the sample chamber. Replacement requires turning off the power, using tools to remove the screws and tubing, installing the new equipment, and checking the seal. The pumping equipment is fixed to the bracket with screws, lacking a quick-release structure, making operation cumbersome and reliant on tools. The threaded sealing of the tubing is time-consuming to disassemble and reassemble, requiring repeated seal checks. It does not consider the needs of immediate nuclear emergency response, focusing only on automation and integration while neglecting ease of maintenance. The range of nuclear contamination spreads over time, and equipment failure and replacement lead to device shutdown. Utility Model Content

The bottom right side of the outer wall of the outer shell 1 is provided with a locking component 306. The locking component 306 can fix the diversion pipe 301 after it is adjusted to a suitable position, to prevent the diversion pipe 301 from being displaced when the liquid flows or the device moves, and ensure the stability of the filtration and separation process. Specifically, the diversion pipe 301 of the filtration mechanism 3 provides a flow and separation channel for the liquid containing impurities, realizing the guiding and diversion of the liquid and impurities.

[0022] Reference Figure 2 , Figure 3 and Figure 6 The bottom of the outer casing 1 is provided with a stabilizing frame 11, which provides bottom support for the entire device and enhances the stability of the device when placed. A fixing block 12 is fixedly connected to the front bottom of the stabilizing frame 11, which provides stable support in contact with the ground when the device is stationary, preventing the device from sliding at will. A connecting block 13 is fixedly connected to the rear bottom of the stabilizing frame 11, and a roller 14 is fixedly connected to the inner bottom wall of the connecting block 13. The roller 14 enables the device to move, greatly reducing the physical exertion of operators when handling the device and improving the mobility of the device at nuclear emergency sites. For convenience, a pull rod 15 is fixedly connected to the top rear end of the stabilizer 11. The pull rod 15 provides a force-applying component for the operator to push or pull the device, making it convenient for the operator to pull the pull rod 15 to move the device. Two limiting plates 16 are fixedly connected to the rear side of the outer wall of the outer shell 1.

The anti-slip sleeve 17 fixed on the top of the pull rod 15 cooperates with the operator's hand to increase the friction between the hand and the pull rod 15, prevent the slippage when the hand is sweaty or when force is applied, and ensure the safety of the operator when pulling the pull rod 15.

[0023] Working Principle: The operator can quickly open the cover plate 4 using the handle 5 on top of the cover plate 4. Opening the cover plate 4 does not affect the operation of internal components. When idle, it can protect the filter mechanism 3 and the radioactive detection probe 7 from dust and contamination. The electric micro-pump 207 is started, and its bottom dropper 208 is inserted into the contaminated liquid to be sampled. The electric micro-pump 207 replaces traditional manual pumping, improving efficiency. After the liquid enters through the dropper 208, the liquid tube 206 fixed to the right side of the insert plate 203 delivers it to the filter mechanism 3 on the right side of the inner wall of the outer casing 1. The filter mechanism 3 performs solid-liquid separation on the liquid containing impurities, preventing impurities from affecting subsequent detection. The separated pure sample enters the detection area. The operator rotates the radioactive detection probe 7 on the left side of the inner wall of the outer casing 1 to adjust its relative position to the sample, ensuring the probe accurately receives the radioactive signal and completes the detection. The detection data is transmitted in real time to the left side of the outer wall of the outer casing 1. The electronic display screen 6 allows operators to read records intuitively. When the electric micro pump 207 needs to be replaced due to a malfunction, the quick-release mechanism 2 initiates the maintenance process. The interlocking block 201 is fixed to the top right side of the outer wall of the outer shell 1, ensuring the stability of the quick-release mechanism 2. Without tools, the operator can directly use the sliding cooperation between the guide rail 205 on the front and rear sides of the outer wall of the insert plate 203 and the sliding groove 202 on the inner wall of the interlocking block 201 to pull the insert plate 203, along with the liquid pipe 206, the electric micro pump 207, and the dripper 208, out from the right side of the interlocking block 201. During this process, the sealing rubber ring 204 on the left side of the insert plate 203 ensures that there is no liquid leakage before disassembly. After replacing the new part, the guide rail 205 is slid into the sliding groove 202 in the opposite direction to complete the quick docking of the insert plate 203 and the interlocking block 201, avoiding long-term shutdown of the device due to component replacement and ensuring continuous sampling and testing in nuclear emergency scenarios. Furthermore, during the liquid processing stage, the contaminated liquid containing impurities, transported via the liquid pipe 206 in the quick-release mechanism 2, enters the diversion pipe 301, which is slidably connected to the right side of the inner wall of the outer casing 1. The diversion pipe 301 provides a directional flow channel for the liquid, preventing it from spreading randomly inside the device. Operators can flexibly adjust the liquid flow rate according to the impurity content by controlling the electric filter flow control valve 304 slidably connected to the outer wall of the diversion pipe 301. When the impurity content is high, the flow rate is slowed down to ensure sufficient retention and filtration of impurities; when the impurity content is low, the flow rate is increased to improve processing efficiency. The electric filter flow control valve 304 has a built-in filter structure that can intercept fine impurities in the liquid, achieving a dual function of flow control and filtration. This solves the problem of traditional filtration relying solely on a single filter screen and incomplete impurity separation. After being processed by the electric filter flow control valve 304, the liquid and impurities flow separately along the internal channels of the diversion pipe 301 to the appropriate channels. The filtered pure sample liquid, guided by the diversion tube 301, flows into the sampling bottle 302, which is slidably connected to the bottom left end of the receiving component. The sliding fit between the sampling bottle 302 and the diversion tube 301 facilitates subsequent removal and testing. The intercepted impurities fall into the waste bin 303, which is slidably connected to the bottom right side of the diversion tube 301. The storage component 305 on the inner wall of the waste bin 303 can seal and temporarily store the impurities to prevent them from overflowing and causing secondary pollution during device movement. To prevent the diversion tube 301 from shifting under the impact of liquid flow, the locking component 306 on the bottom right side of the outer wall of the outer shell 1 can fix the position of the diversion tube 301, ensuring that the diversion, filtration and receiving processes are stable. This solves the problem in the prior art where a loose diversion structure can cause sample and impurity mixing. The entire process does not require complicated manual operation, which greatly improves the separation efficiency and reliability of liquids containing impurities in nuclear emergency scenarios.
