Abstract
Description
Technical Field
[0001] This application relates to the field of water quality testing, and in particular to a water quality radionuclide detection device. Background Technology
[0002] Water is a basic necessity for human survival, but it is also a significant medium for the spread of diseases and harmful substances. River water may contain radioactive materials that pose a threat to human health. This radioactivity primarily originates from naturally occurring radioactive nuclides such as uranium, radium, thorium, and potassium found in rocks and soil. Furthermore, artificial radioactive nuclides produced during nuclear tests and accidents can enter river water bodies, potentially increasing the radioactivity levels of the water source. Radioactive nuclides in the river environment can cause external radiation exposure to humans, and can also cause internal radiation exposure through the ingestion of drinking water, aquatic organisms, or terrestrial food contaminated by irrigation, thus posing health risks. Therefore, regular radionuclide monitoring of river water bodies is necessary.
[0003] Currently, most radionuclide detection in river water involves manually submerging detectors periodically into the water for radionuclide analysis. However, this process often requires sequential testing of multiple sections of river branches in various locations, necessitating repeated submersions, which is time-consuming, labor-intensive, and ineffective for real-time monitoring. Furthermore, some methods of radionuclide detection in river water involve directly placing detectors in the river for real-time monitoring. In severe weather, especially strong winds, underwater detectors are easily affected, causing them to agitate and potentially colliding with hard debris in the river, resulting in damage and shortening their lifespan.

[0025] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections (linkages).
[0026] The following is combined with Figures 1 to 3 The provided embodiments further illustrate the water quality radionuclide detection equipment proposed in this application.
[0027] like Figure 1 , Figure 3As shown, an embodiment of this application provides a water quality radionuclide detection device, including a support column 1, a base 7 buried in the riverbed at the bottom of the support column 1, and a placement box 2 installed at the upper part of the support column 1 above the water surface. The placement box 2 has a placement cavity 3 inside. A first opening 25 extending into the placement cavity 3 is provided at the bottom of the placement box 2. A first drive shaft 9 arranged along a first direction is provided inside the placement cavity 3. In some embodiments, the first direction is along the length of the placement cavity 3. A reversible motor 12 is provided on the placement box 2. The output end of the motor 12 is connected to the first drive shaft 9 and can drive the first drive shaft 9 to rotate. A winding roller 11 is provided on the first drive shaft 9, and a traction rope is wound on the winding roller 11. The free end of the traction rope passes through the first opening 25 and is connected to a radionuclide detector 23 for detecting river water quality. In some embodiments, the top of the radionuclide detector 23 has a protrusion or buckle for connecting the traction rope. The traction rope is connected to the top of the radionuclide detector 23 to lift the radionuclide detector 23 for traction operation. The placement box 2 is equipped with a processor 22 and a wireless communication module 36. The processor 22 is connected to the motor 12, the nuclide detector 23 and the wireless communication module 36 respectively. Normally, the radionuclide detector 23 is submerged in the water to detect radionuclides in the river water and feeds the results back to the processor 22 in real time. The processor 22 then transmits the data detected by the radionuclide detector 23 to the outside world in real time via the wireless communication module 36, avoiding the need for staff to travel to multiple river branches for testing. In case of severe weather such as thunderstorms or strong winds, the processor 22 can automatically control the motor 12 according to the instructions sent by the staff. The motor 12 drives the first drive shaft 9 to rotate and wind up the traction rope until the radionuclide detector 23 passes through the first opening 25 and enters the installation cavity 3. This avoids damage to the radionuclide detector 23 from collisions with foreign objects in the water during severe weather, ensuring the service life of the radionuclide detector 23. When the weather returns to normal, the processor 22 can automatically control the motor 12 according to the instructions. The motor 12 drives the first drive shaft 9 to rotate in the opposite direction to release the traction rope, allowing the radionuclide detector 23 to be submerged in the water again for testing.
[0028] like Figure 1 As shown, in some embodiments, the base 7 is preferably made of a material with a heavier counterweight, and the weight of the base 7 is greater than the weight of other accessories on the support column 1, so that the support column 1 stands more stably in the water.
[0029] like Figure 1As shown, in some embodiments, an arc-shaped guide ramp 26 is provided at the bottom of the placement box 2 at the first opening 25, and the diameter of the guide ramp 26 gradually decreases from bottom to top. By providing the funnel-shaped guide ramp 26, the nuclide detector 23 being recovered can be effectively guided, allowing the nuclide detector 23 to smoothly enter the first opening, avoiding the nuclide detector 23 from getting stuck outside the placement box 2 or from being damaged by direct collision with the placement box 2. Furthermore, a flexible material such as rubber can be provided on the outer surface of the guide ramp 26 to reduce the collision between the nuclide detector 23 and the guide ramp 26.
[0030] like Figure 1 As shown, in some embodiments, a counterweight 33 is provided at the bottom of the nuclide detector 23. The counterweight 33 increases the weight of the nuclide detector 23. When the motor 12 drives the first transmission shaft 9 to rotate to release the traction rope, the nuclide detector 23 can move directly down until it is submerged in the water under the drive of the counterweight 33.
[0031] like Figure 1 As shown, in some embodiments, the width of the counterweight 33 is greater than the width of the nuclide detector 23. A guide frame 27 is provided at the bottom of the placement cavity 3, positioned above the first opening 25. A limiting ring 34 is provided on the inner wall of the guide frame 27. The width of the opening of the limiting ring 34 is greater than the width of the nuclide detector 23, but less than the width of the counterweight 33. The guide frame 27 further guides the nuclide detector 23 as it enters the placement cavity 3, ensuring it remains upright within the cavity. The guide frame 27 also guides the downward deployment of the nuclide detector 23. The limiting ring 34, with an opening width greater than the nuclide detector 23 and less than the counterweight 33, limits the travel distance of the nuclide detector 23 during retrieval. When the counterweight 33 touches the limiting ring 34, the nuclide detector 23 is restricted and stops rising, preventing it from colliding with the first and second drive shafts.
[0032] like Figure 2 and Figure 3As shown, in some embodiments, a second drive shaft 13 parallel to the first drive shaft 9 may also be provided in the mounting cavity 3. The installation height of the second drive shaft 13 is lower than that of the first drive shaft 9. A second pulley 14 is provided on the first drive shaft 9, and a third pulley 15 is provided on the second drive shaft 13. The second pulley 14 and the third pulley 15 are connected by a drive belt. A drive roller 16 is provided on the second drive shaft 13. The outer circumference of the drive roller 16 is provided with a groove 17 that connects end to end along its length. A guide rod 28 is provided between the drive shaft 9 and the second drive shaft 13. The guide rod 28 is parallel to the first drive shaft 9. A drive block 29 is provided on the guide rod 28. The drive block 29 is slidably connected to the guide rod 28. A slider 32 is provided at the end of the drive block 29 that is close to the drive roller 16. The slider 32 is slidably connected to the slide groove 17. A guide ear seat 30 is provided at the end of the drive block 29 that is close to the take-up roller 11. A through hole 31 is provided on the guide ear seat 30, and the traction rope passes through the through hole 31. When the motor 12 drives the first transmission shaft 9 to rotate, the first transmission shaft 9 drives the second pulley 14 to rotate. The second pulley 14 drives the third pulley 15 to rotate via the transmission belt. The rotation of the third pulley 15 drives the second transmission shaft 13 and the drive roller 16, which are concentric with it, to rotate. The rotation of the drive roller 16 then drives the drive block 29 to slide back and forth along the guide rod 28 through the sliding groove 17 and the sliding connection between the drive roller 16 and the slider 32. This drives the traction rope passing through the through hole 31 on the guide ear seat 30 to move back and forth, so that the traction rope is evenly wound on the take-up roller 11 and avoids knotting.
[0033] like Figure 1 and Figure 3 As shown, in some embodiments, two brush discs 21 are symmetrically arranged at the lower part of the mounting cavity 3. The two brush discs 21 are located on both sides of the first opening 25, and the opposite surfaces of the two brush discs 21 are respectively provided with bristles for cleaning the outer surface of the nuclide detector 23 entering the mounting cavity 3. Each of the two brush discs 21 is connected to a third drive shaft 19. Two bearing plates 18 are arranged in the mounting cavity 3 along the second direction. The two third drive shafts 19 are respectively mounted between the corresponding bearing plates 18 and the inner wall of the mounting cavity 3, and both third drive shafts 19 are parallel to the first drive shaft 9. The first drive shaft 9 is provided with two first pulleys 10, and the two third drive shafts 19 are respectively provided with fourth pulleys 20 corresponding to the first pulleys 10. The first pulleys 10 and the corresponding fourth pulleys 20 are connected by a drive belt. When the motor 12 drives the first drive shaft 9 to rotate, the rotation of the first drive shaft 9 drives the first pulley 10 to rotate. The rotation of the first pulley 10 drives the fourth pulley 20 to rotate through the transmission belt. The rotation of the fourth pulley 20 drives the two third drive shafts 19 and the two brush discs 21 to rotate. In this way, the bristles on the brush discs 21 can clean the dirt on the surface of the nuclide detector 23 that has been recovered into the placement cavity 3.
[0034] like Figure 1 As shown, in some embodiments, an anemometer 5 and a wind vane 6 are also installed on the top of the housing 2, and the anemometer 5 and wind vane 6 are connected to the processor 22. The anemometer 5 and wind vane 6 are used to monitor the external wind force in real time. When strong winds occur, the anemometer 5 detects excessive wind speed and feeds the data back to the processor 22. After receiving the strong wind signal, the processor 22 controls the motor 12 to work and automatically retrieve the nuclide detector 23. The processor 22 can also transmit the monitoring data of the anemometer 5 and wind vane 6 to the outside in real time through the wireless communication module 36, so that the staff can understand the working status of the equipment and react in a timely manner.
[0035] like Figure 1 As shown, in some embodiments, the placement box 2 is provided with a display screen 4, which is connected to the processor 22 and is used to display the nuclide information detected by the nuclide detector 23.
[0036] like Figure 1 As shown, in some embodiments, the placement box 2 is also equipped with an alarm 35, which is connected to the processor 22. When the nuclide detector 23 detects an abnormality in the nuclides in the water, the alarm 35 issues an alarm signal. Furthermore, in some embodiments, the alarm 35 can be a red LED light.
[0037] like Figure 1 As shown, in some embodiments, a storage battery 24 is installed inside the installation box 2, and the processor 22 is connected to the storage battery 24. The storage battery 24 supplies power to various electrical components inside and outside the installation box 2 through the power distribution module in the processor 22 to ensure their normal operation.
[0038] like Figure 1 As shown, in some embodiments, the motor 12 is mounted on the outer wall of the mounting box 2, and the outer wall of the mounting box 2 is provided with a rain shield 8 located above the motor 12. The rain shield 8 can prevent the motor 12 from being directly exposed to the sun and rain, thus extending the service life of the motor 12.
[0039] It is understood that the above embodiments only illustrate preferred embodiments of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this application. It should be noted that, for those skilled in the art, without departing from the concept of this application, the above technical features can be freely combined, and several modifications and improvements can be made, all of which fall within the protection scope of this application. Therefore, all equivalent transformations and modifications made within the scope of the claims of this application should fall within the coverage of the claims of this application.
