Description

Technical Field

[0001] The utility model relates to the technical field of water quality monitoring, in particular to a sampling structure and water quality monitoring equipment. Background Art

[0002] During outdoor construction, a large number of exposed construction surfaces are easily formed. Rainwater erosion during the flood season will cause soil erosion and affect the water quality of the downstream river. Therefore, construction units generally purify the polluted water bodies upstream. After the treatment is completed, the water flow will be sampled and tested through a sampling device to verify the purification effect. However, most existing sampling devices are cylindrical containers, which are generally only suitable for sampling in still water. When they fall into the flowing water for sampling, they are easy to flow downward with the water flow, making it difficult to sample the lower layer of the flowing water, thus affecting the monitoring effect. Some equipment that can sample deep flowing water requires auxiliary devices such as vertical guide rails, which are cumbersome to operate and not conducive to improving sampling efficiency.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1, reference Figures 1 to 5 , is the first embodiment of the present invention, which provides a sampling structure, including a sampling assembly 100, including a sampling tube 101, and a sampling cavity 102 opened inside the sampling tube 101, and a sampling hole 103 is provided on the sampling cavity 102. When sampling, the sampling tube 101 can be placed vertically in water, and under the action of water pressure, the water will flow along the sampling hole 103 into the sampling cavity 102, thereby completing the sampling work, such as Figure 2 As shown, the sampling tube 101 is provided with multiple sampling tubes 101 and sampling holes 103 according to different depths, so that the flowing water between multiple layers can be sampled simultaneously during sampling. This not only allows multiple groups of samples to be obtained to improve the water quality detection effect, but also increases the sampling efficiency of the samples. The suspension component 200 includes a floating ring 201 that is sleeved on the outside of the sampling tube 101. The sampling tube 101 is provided with a traction member 209 for pulling the sampling tube 101. The floating ring 201 is hollow and the buoyancy it receives in the water is much greater than the gravity of itself and the sampling tube 101, so it can ensure that the sampling tube 101 is vertically suspended in the flowing water. In addition, the staff can use the traction member 209 to maintain the sampling tube 101 in one position to ensure the normal progress of the sampling work.

[0030] Furthermore, a fixed support rod 202 is provided inside the floating ring 201, and a mounting sleeve 203 is fixedly installed on the side of the fixed support rod 202 away from the floating ring 201. A fitting plate 204 is fixedly installed on the upper end of the fitting sleeve 203, which is close to the outer wall of the sampling tube 101. The fitting plate 204 is made of elastic material. Figure 2 As shown, the sampling tube 101 is located inside the mounting sleeve 203, and the bonding plate 204 thereon achieves fixation between the floating ring 201 and the sampling tube 101 by squeezing the inner wall of the sampling tube 101, ensuring that the sampling tube 101 can be vertically suspended in the flowing water, making it easy to obtain flowing water samples at various levels.

[0031] Furthermore, a fastening sleeve 205 is threadedly mounted on the exterior of the mounting sleeve 203. Inside the fastening sleeve 205, a squeeze ring block 206 is disposed for contacting the bonding plate 204. The inner wall of the squeeze ring block 206 gradually extends inward, away from the floating ring 201. Because the inner wall of the squeeze ring block 206 gradually extends inward, away from the floating ring 201, when the squeeze ring block 206 is mounted on the exterior of the bonding plate 204, it presses the bonding plate 204 toward the sampling tube 101, increasing friction between the squeeze ring block 206 and the sampling tube 101 and improving the mounting stability between the floating ring 201 and the sampling tube 101. To adjust the sampling depth, the fastening sleeve 205 can be rotated to disengage the squeeze ring block 206 from the bonding plate 204, reducing friction between the bonding plate 204 and the sampling tube 101. At this point, the floating ring 201 can be freely slid on the sampling tube 101 to adjust the sampling depth.

[0032] During use, the sampling tube 101 is vertically suspended in the flowing water by the setting of the floating ring 201, and is maintained in one position by cooperating with the traction member 209 to ensure the normal progress of the sampling work. In addition, the setting of the fastening sleeve 205 and the extrusion ring block 206 allows the floating ring 201 to move freely on the sampling tube 101 to adjust the sampling depth, making it convenient for staff to sample deep flowing water.

[0033] Example 2, reference Figure 3 and Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, it further includes a traction member 209 comprising a winding roller 209a disposed at one end of the sampling barrel 101. A traction rope 209b having one end fixedly connected to the sampling barrel 101 is wound around the outer surface of the winding roller 209a. The provision of the traction rope 209b facilitates the staff in pulling the sampling barrel 101 on the shore, maintaining it in one position and facilitating sampling. Furthermore, during the traction process, the traction rope 209b opposes the impact force of the flowing water, causing the sampling barrel 101 and the floating ring 201 to have a tendency to tip over. However, this also increases the buoyancy of the floating ring 201, ensuring that the sampling barrel 101 and the floating ring 201 do not tip over.

[0034] Furthermore, a fixed screw 209c is fixedly mounted on one end of the winding roller 209a near the sampling barrel 101. The fixed screw 209c is externally threadedly sleeved with a fixed sleeve 209d that is fixedly connected to the sampling barrel 101. The provision of the fixed screw 209c and the fixed sleeve 209d realizes a detachable connection between the winding roller 209a and the sampling barrel 101, facilitating the fixing of the winding roller 209a to the sampling barrel 101 after use.

[0035] Furthermore, the upper and lower end surfaces of the fixed support rod 202 are respectively provided with a coaxially fixed indicator block 207 and a synchronization block 208. The rotating end of the synchronization block 208 is rotationally connected to the fixed support rod 202, and the side thereof close to the fixed support rod 202 is in contact with the fixed support rod 202. The surface roughness of the fixed support rod 202 is relatively large, and a triangular indicator groove is provided on the fastening sleeve 205. Since the indicator block 207 and the synchronization block 208 are rotationally connected to the fixed support rod 202, when they fall into the flowing water, they will rotate under the action of the flowing water, and their indicating direction will gradually become consistent with the direction of the flowing water. After the sampling is completed, the staff observes the indication of the synchronization block 208 with the triangular indicator groove as the indicating direction, thereby judging the direction of the flowing water, which can help scientific researchers simulate the propagation process of pollutants in water and predict their possible diffusion range. This is of great significance for taking targeted measures for governance and prevention in a timely manner, and helps to reduce the damage of pollution to the aquatic ecology. In addition, since the surface roughness of the fixed support rod 202 is relatively large, the friction between the remaining synchronous blocks 208 is relatively large. When the fixed support rod 202 is raised to the surface of the water, the synchronous blocks 208 are not prone to large deviations under the influence of factors such as gravity, which is beneficial for staff to judge the direction of river flow.

[0036] During use, the setting of the traction member 209 allows the sampling tube 101 to be maintained in one position, facilitating the normal sampling work. At the same time, the setting of the indicator block 207 and the synchronization block 208 facilitates the staff to judge the direction of water flow, which is beneficial for the staff to simulate the propagation process of pollutants in water.

[0037] Example 3, reference Figure 6 and Figure 7 , which is the third embodiment of the present utility model, and this embodiment further provides a water quality monitoring device. It includes a sealing component 300, including a sealing slot 301 opened on the inner wall of the sampling cavity 102 and close to the sampling hole 103, and a sealing disc 302 for sealing the sampling hole 103 is slidably installed in the sealing slot 301, and the sealing disc 302 is hollow in design. Since the sealing disc 302 is hollow in design, its buoyancy in water is greater than its own gravity. Therefore, when the flowing water enters the sampling cavity 102 through the sampling hole 103, the sealing disc 302 will slowly float up until the sampling hole 103 is blocked, so that the sample in the sampling cavity 102 will not overflow from the sampling hole 103, thereby preventing the pollutants therein from affecting the external environment. The drainage component 400 includes a liquid outlet 401 arranged on the inner wall of the sampling cavity 102 and connected to the outside world. The design of the liquid outlet 401 facilitates the discharge of the sample in the sampling cavity 102 into the detection device.

[0038] Furthermore, the drainage assembly 400 also includes a movable chamber 402 disposed within the sampling tube 101 and communicating with the liquid outlet 401. A partition 403 is slidably mounted within the movable chamber 402 for blocking the liquid outlet 401. The partition 403 is provided with a lower liquid hole 404 corresponding to the liquid outlet 401. A drainage spring 405 is provided at one end of the movable chamber 402 and is fixedly connected to the partition 403. Under normal conditions, the lower liquid hole 404 on the partition 403 does not correspond to the liquid outlet 401, so that the sample cannot flow out of the liquid outlet 401. During drainage, the partition 403 is pulled downward to align the lower liquid hole 404 with the liquid outlet 401, facilitating the discharge of the sample from both the liquid outlet 401 and the lower liquid hole 404. After drainage is complete, the partition 403 is released, and under the action of the drainage spring 405, the partition 403 re-blocks the liquid outlet 401.

[0039] Furthermore, a connecting thread is provided on the inner wall of the liquid outlet 401. The setting of the connecting thread facilitates the connection between the connecting pipe in the detection device and the liquid outlet 401, thereby avoiding the situation where the multiple sampling chambers 102 discharge in a disorderly manner.

[0040] During use, the blocking disc 302 and the blocking slot 301 can prevent the sample in the sampling cavity 102 from escaping after the sampling is completed, thereby preventing the pollutants therein from affecting the external environment.
