Technical Field

[0001] This invention belongs to the field of water environment monitoring technology, and specifically relates to a device for detecting nitrogen and phosphorus pollution in water environment sediments. Background Technology

[0002] Water environment monitoring refers to the systematic analysis of the composition, physicochemical properties, and biological characteristics of water bodies (such as surface water, groundwater, seawater, and wastewater) using physical, chemical, and biological techniques. This process aims to assess water quality, identify pollution sources, monitor pollution trends, and provide scientific evidence for water resource protection, pollution control, environmental management, and public health protection.

[0003] When conducting nitrogen and phosphorus pollution detection in aquatic sediments, detection devices are required. The commonly used detection device is a COD detector. This is done by bringing the COD detector to the site and then taking samples for testing. However, when using existing COD detectors, the area where the detector is placed may not be level. This causes the test tube containing sediment to be placed in the detector at an angle, resulting in an uneven sediment surface, uneven sediment deposition to one side, and affecting the test results.

[0004] Therefore, it is necessary to invent a device for detecting nitrogen and phosphorus pollution in aquatic sediments to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a device for detecting nitrogen and phosphorus pollution in aquatic sediments, thereby resolving the issues raised in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for detecting nitrogen and phosphorus pollution in aquatic sediments, comprising: a body, wherein a leveling and detection component is provided inside the body, the leveling and detection component is capable of leveling and detecting a detection tube containing sediment to be detected, and a sealing component is provided on the body; The leveling and detection assembly includes: a ball head sleeve, a ball head, a counterweight, a fixing assembly, a straightening assembly, and a detection head; The ball head sleeve is fixedly installed inside the machine body. The ball head is rotatably installed inside the ball head sleeve. A groove is provided on the top of the ball head. The straightening component is set in the groove. The straightening component can straighten the inserted detection tube. The counterweight is fixedly installed in the middle of the bottom end of the ball head. The fixing component is set on the ball head sleeve. The fixing component can fix the ball head. The detection head is set in the middle of the bottom wall of the groove.

[0007] Furthermore, the fixing component includes: a slider, a first electromagnet, and a first spring; The ball head sleeve has symmetrically arranged mounting slots inside. The first electromagnet is placed in the mounting slot. The slider is symmetrically fixedly installed outside the first electromagnet. The slider is slidably installed in the mounting slot. The first spring fixes the side of the slider near the ball head to the inner wall of the mounting slot. The ball head is made of iron.

[0008] Furthermore, the straightening component includes: an arc-shaped plate, a connecting rod, an iron plate, a second spring, and a second electromagnet; The arc-shaped plates are equidistantly arranged around the groove. The ball head has a cavity corresponding to the arc-shaped plates inside. The iron plate is slidably arranged in the cavity. The second electromagnet is fixedly installed on the inner wall of the cavity on the side away from the iron plate. The second spring is sleeved on the outside of the connecting rod. The two ends of the connecting rod are fixedly connected to the iron plate and the arc-shaped plates, respectively.

[0009] Furthermore, an annular groove is formed on the bottom wall of the groove, and an annular plate is slidably installed in the annular groove. A support plate is fixedly connected to the top of the annular plate by a straight rod, and the bottom of the annular plate is fixedly connected to the bottom wall of the annular groove by a third spring. A retaining ring is fixedly installed on the inner wall of the annular groove.

[0010] Furthermore, the ball head has a battery inside and a charging port on the outside. The charging port is connected to the battery via a power line, and the battery can supply power to the detection head and the second electromagnet.

[0012] Furthermore, an embedding groove is provided in the middle of the bottom wall of the groove, and the detection head is fixedly installed in the embedding groove. The top of the detection head is flush with the bottom wall of the groove. The detection tube containing the deposit can rely on its own weight to overcome the elastic force of the third spring to drive the support plate to descend to the top and be flush with the bottom wall of the groove.

[0013] Furthermore, the weight of the counterweight is sufficient to drive the ball head to rotate the arc plate to a vertical position under the action of gravity.

[0014] The technical effects and advantages of this invention are as follows: 1.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0017] This invention provides a device for detecting nitrogen and phosphorus pollution in aquatic sediments, such as... Figures 1 to 6 As shown, it includes: a body 1, an internal leveling and detection component, which can level and detect the detection tube containing the sediment to be detected, and a capping component on the body 1. The body 1 is a portable COD detector in the prior art, and the body 1 can detect sediment.

[0018] The leveling and testing components include: ball head sleeve 2, ball head 3, counterweight 4, fixing components, straightening components, and testing head 20; The ball head sleeve 2 is fixedly installed inside the body 1, and the ball head 3 is rotatably installed inside the ball head sleeve 2. The top of the ball head 3 has a groove, and the straightening component is set in the groove. The straightening component can straighten the inserted detection tube. The counterweight block 4 is fixedly installed in the middle of the bottom end of the ball head 3. The fixing component is set on the ball head sleeve 2 and can fix the ball head 3. The detection head 20 is set in the middle of the bottom wall of the groove. The detection head 20 is the detection head 20 on the portable COD detector in the prior art.

[0019] In use, place the machine body 1 on the ground, then rotate the sealing assembly to open the groove on the machine body 1. Then, under the action of gravity, the counterweight 4 carries the ball head 3 to rotate inside the ball head sleeve 2. Finally, the ball head 3 stops moving, and the bottom wall of the groove is in a horizontal state. The ball head 3 is fixed by the fixing assembly. Then, the detection tube containing the sediment is placed into the groove. The straightening assembly straightens the detection tube to make it vertical. Finally, the entire detection tube is in a vertical state. Then, the detection head 20 is used for detection. The detection results are displayed on the machine body 1. This completes the detection of nitrogen and phosphorus pollution in the sediment. Because when the detection tube is placed into the groove, there may be a misoperation that causes the detection tube to press against the inner wall of the groove, causing the ball head 3 to deflect, which requires readjustment; Therefore, by setting the groove diameter to be larger than the detection tube diameter, the above-mentioned problems can be avoided when the detection tube is inserted. Then, the detection tube is straightened by the straightening component to make it vertical, so that the detection tube is in a vertical state for detection. This ensures that the liquid level of the sediment in the detection tube is horizontal and the sediment is evenly distributed, thus making the detection results more accurate.

[0020] like Figure 4 As shown, the fixing assembly includes: slider 5, first electromagnet 6, and first spring 7; The ball head sleeve 2 has symmetrically opened mounting grooves inside. The first electromagnet 6 is set in the mounting groove. The slider 5 is symmetrically fixedly installed on the outside of the first electromagnet 6. The slider 5 is slidably installed in the mounting groove. The first spring 7 fixes the side of the slider 5 near the ball head 3 to the inner wall of the mounting groove. The ball head 3 is made of iron.

[0021] When the first electromagnet 6 is energized, it becomes magnetic, causing the first electromagnet 6 to move the slider 5 towards the ball head 3. As the slider 5 moves, it compresses the first spring 7, causing it to deform. Finally, the first electromagnet 6 attracts and fixes the ball head 3, thus fixing the ball head 3. When the first electromagnet 6 is de-energized, it loses its magnetism. At this time, the first spring 7, along with the slider 5 and the first electromagnet 6, resets, thus releasing the fixation of the ball head 3.

[0022] like Figure 3 and Figure 4As shown, the straightening assembly includes: an arc plate 8, a connecting rod 9, an iron plate 10, a second spring 11, and a second electromagnet 12; The arc-shaped plates 8 are equidistantly arranged around the groove. The ball head 3 has a cavity corresponding to the arc-shaped plates 8 inside. The iron plate 10 is slidably arranged in the cavity. The second electromagnet 12 is fixedly installed on the inner wall of the cavity on the side away from the iron plate 10. The second spring 11 is sleeved on the outside of the connecting rod 9. The two ends of the connecting rod 9 are fixedly connected to the iron plate 10 and the arc-shaped plates 8 respectively. The iron plate 10 is rectangular in shape.

[0023] When the second electromagnet 12 is energized, it becomes magnetic, thereby attracting the iron plate 10, along with the connecting rod 9 and the arc plate 8, to move towards the detection tube. Finally, the multiple arc plates 8 work together to straighten the detection tube and make it vertical. During the movement of the iron plate 10, the second spring 11 is compressed and deformed. When the second electromagnet 12 is de-energized, it loses its magnetism. At this time, the second spring 11, along with the iron plate 10, the connecting rod 9, and the arc plate 8, returns to its original position.

[0024] like Figure 3 and Figure 4 As shown, an annular groove is provided on the bottom wall of the groove, and an annular plate 13 is slidably installed in the annular groove. The top of the annular plate 13 is fixedly connected to the support plate 15 by a straight rod 14, and the bottom of the annular plate 13 is fixedly connected to the bottom wall of the annular groove by a third spring 16. A retaining ring 17 is fixedly installed on the inner wall of the annular groove.

[0025] If the test tube slips and falls directly onto the bottom wall of the groove when it is inserted, it will cause the test head 20 to collide. Over time, the test head 20 will be frequently vibrated, which will easily cause it to be damaged. Therefore, when the detection tube falls due to a slip of the hand, it lands on the support plate 15, which presses down the straight rod 14 and the ring plate 13. The ring plate 13 compresses the third spring 16. The compression of the third spring 16 can buffer the impact of the fall and play a shock absorption role, thus protecting the detection head 20. Finally, the detection tube moves with the support plate 15 until the top of the support plate 15 is flush with the top of the detection head 20.

[0026] like Figure 3 As shown, the ball head 3 has a battery 18 inside and a charging port 19 on the outside. The charging port 19 is connected to the battery 18 through a power transmission line. The battery 18 can supply power to the detection head 20 and the second electromagnet 12.

[0027] This ensures that the ball head 3 is not affected by the power transmission line when rotating, thus guaranteeing the normal rotation of the ball head 3.

[0028] like Figure 4 As shown, the sealing assembly includes: a sealing cap 21 and a foam ring 22; The cover 21 is rotatably mounted on the body 1, and the sponge ring 22 is fixedly mounted inside the cover 21. The bottom of the sponge ring 22 is provided with a flared opening, and the sponge ring 22 can be fitted onto the outside of multiple arc plates 8.

[0029] When not in use, the sponge ring 22 encircles multiple curved plates 8, thereby restricting the ball head 3 and preventing it from swinging around. This avoids the counterweight 4 from colliding with the ball head sleeve 2 and causing vibration, thus preventing the detection head 20 from being vibrated and protecting the detection head 20.

[0030] An embedding groove is provided in the middle of the bottom wall of the groove. The detection head 20 is fixedly installed in the embedding groove. The top of the detection head 20 is flush with the bottom wall of the groove. The detection tube containing the sediment can rely on its own weight to overcome the elastic force of the third spring 16 to drive the support plate 15 to descend to the top and be flush with the bottom wall of the groove. This ensures that the top of the final detection head 20 fits snugly against the bottom of the detection tube, allowing for better detection.

[0031] like Figure 3 As shown, the weight of the counterweight 4 is sufficient to drive the ball head 3 to rotate the arc plate 8 to a vertical position under the action of gravity.

[0032] This ensures that under the action of gravity, the counterweight 4 rotates with the ball head 3 and the arc plate 8 for adjustment, and finally straightens the arc plate 8 so that it is in a vertical state.

[0033] Working principle: In use, place the machine body 1 on the ground, then rotate the cover assembly to open the groove on the machine body 1. After the sponge ring 22 leaves the multiple arc plates 8, under the action of gravity, the counterweight 4 carries the ball head 3 to rotate inside the ball head sleeve 2. Finally, the ball head 3 stops moving, and the bottom wall of the groove is in a horizontal state. The first electromagnet 6 is energized to make it magnetic, so that the first electromagnet 6 carries the slider 5 towards the ball head 3. As the slider 5 moves, it compresses the first spring 7, causing it to deform. Finally, the first... Electromagnet 6 is attracted and fixed to ball head 3, thus fixing ball head 3. The second electromagnet 12 is energized to make it magnetic, thereby attracting iron plate 10, connecting rod 9 and arc plate 8 to move towards the detection tube. Finally, multiple arc plates 8 work together to straighten the detection tube and make it vertical. During the movement of iron plate 10, the second spring 11 is compressed and deformed. Finally, the entire detection tube is in a vertical state. Then, it is detected by detection head 20. The detection result is displayed on the body 1. Thus, the detection of nitrogen and phosphorus pollution in sediment is completed. Because when the detection tube is placed into the groove, there may be a misoperation that causes the detection tube to press against the inner wall of the groove, causing the ball head 3 to deflect, which requires readjustment; Therefore, the groove is set to have a diameter larger than that of the detection tube to avoid the above-mentioned problems when the detection tube is inserted. Then, multiple arc plates 8 are used to straighten the detection tube and make it vertical, so that the detection tube can be tested in a vertical state. This ensures that the liquid level of the sediment in the detection tube is horizontal and the sediment is evenly distributed, thus making the test results more accurate. If the test tube slips and falls directly onto the bottom wall of the groove when it is inserted, it will cause the test head 20 to collide. Over time, the test head 20 will be frequently vibrated, which will easily cause it to be damaged. Therefore, when the detection tube falls due to a slip of the hand, it lands on the support plate 15, which presses down the straight rod 14 and the ring plate 13. The ring plate 13 compresses the third spring 16. The compression of the third spring 16 can buffer the impact of the fall and play a shock absorption role, thus protecting the detection head 20. Finally, the detection tube moves with the support plate 15 until the top of the support plate 15 is flush with the top of the detection head 20, and then the detection operation is performed. When the detection tube needs to be removed, the second electromagnet 12 is de-energized to demagnetize it. At this time, the second spring 11, along with the iron plate 10, connecting rod 9, and arc plate 8, resets. Then the detection tube is removed, and the third spring 16, along with the ring plate 13, straight rod 14, and support plate 15, rises and resets.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
