Description

Technical Field

[0001] This utility model relates to the field of sewage sampling technology, and in particular to a river sewage sampling device for rural environmental protection monitoring. Background Technology

[0002] River wastewater monitoring refers to the monitoring and analysis of wastewater in rivers to determine its pollution level and composition, thereby enabling appropriate remediation measures to be taken. River wastewater monitoring is an important component of urban water environment management, aiming to promptly identify and control pollution sources, ensure river water quality safety, and promote the sustainable use of water resources. The main purpose of river wastewater monitoring is to promptly identify and control pollution sources, ensure river water quality safety, and promote the sustainable use of water resources. Through monitoring, the pollution status of rivers can be understood, providing a scientific basis for environmental protection and water resource management. River wastewater monitoring requires the initial sampling of river wastewater using sampling devices.

[0003] A search revealed that patent CN217237310U discloses a river sewage sampling device for rural environmental protection monitoring. This device involves vertically inserting a sampling box into the water body. A control switch activates a drive motor, which rotates a threaded rod. A threaded sleeve on the side of a baffle is threadedly connected to the threaded rod, and a sliding sleeve on the side of the baffle is slidably connected to the sliding rod, causing the baffle to slide within the inner cavity. When the through-hole connects to the input end of the sampling bottle, the baffle contacts a stop switch on the upper edge of the inner cavity, stopping the drive motor and allowing sewage to enter the sampling bottle through the through-hole. However, this device shares the same drawbacks as existing sewage sampling devices: it requires manual insertion into the water, necessitating a boat trip to the middle of the river to collect samples. Furthermore, its limited size restricts sampling from deeper water. Additionally, multiple sampling bottles are used simultaneously, preventing the storage of samples from different locations and thus limiting the ability to collect multiple samples at once. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a river sewage sampling device for rural environmental protection monitoring.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a river sewage sampling device for rural environmental protection monitoring, comprising a sampling cylinder, a base, and multiple crossbars.

[0022] like Figures 1-3As shown, a river sewage sampling device for rural environmental protection monitoring is disclosed, including a sampling cylinder 1, a base 10 and multiple crossbars 15. The sampling cylinder 1 is divided into a bottom cavity 101 and a top cavity 102 by a partition. A top cover 2 is covered on the top surface of the sampling cylinder 1, and a sampling port 21 is provided on one side of the top cover 2. A servo motor 4 is fixed on the top wall inside the bottom cavity 101. The output shaft of the servo motor 4 extends into the top cavity 102 and is fixedly connected to a base plate 5. A top seat 7 is provided above the base plate 5. Multiple elastic support components 6 are fixed between the top seat 7 and the base plate 5. Multiple positioning grooves 8 are provided on the side of the upper surface of the top seat 7. A sample storage bottle 9 is provided inside each positioning groove 8. The diameter of the sample storage bottle 9 is larger than the diameter of the sampling port 21.

[0023] Each crossbar 15 has a threaded head 16 fixed at one end, and a threaded groove for screwing the threaded head 16 into the other end of the crossbar 15. A vertical plate 14 is fixed on the upper surface of the base 10. A through hole 141 for inserting the crossbar 15 is opened at the top of the vertical plate 14. A bracket 11 is fixed on the upper surface of the base 10, and a spool 12 is rotatably connected to the top of the bracket 11. A steel wire rope 13 is wound on the surface of the spool 12. A guide ring for passing through the steel wire rope 13 is fixed on the surface of the crossbar 15 near the threaded head 16. The end of the steel wire rope 13 away from the spool 12 passes through the guide ring and is fixedly connected to the upper surface of the top cover 2.

[0024] A filter screen 3 is fixed inside the sample inlet 21.

[0025] When sewage from the river enters through the inlet 21, the filter screen 3 prevents large particulate impurities in the sewage from entering the sample storage bottle 9.

[0026] The top cover 2 has a first locking bolt 22 that runs through the side wall and is threadedly connected, and a sealing gasket is fixed to the inner top wall of the top cover 2.

[0027] When each positioning slot 8 contains a sample bottle 9, the top cover 2 is placed on top of the sampling cylinder 1, and the first locking bolt 22 is tightened to fix the top cover 2.

[0028] The elastic support assembly 6 includes a vertical tube 61 fixed to the upper surface of the base plate 5, a vertical rod 62 slidably connected inside the vertical tube 61, and the top end of the vertical rod 62 is fixedly connected to the lower surface of the top seat 7. A spring 63 is fixedly connected to the bottom end of the vertical rod 62 and the bottom end of the vertical tube 61.

[0029] When the top cover 2 is fixed to the top of the sampling cylinder 1, the top of the sample bottle 9 will fit tightly against the inner top wall of the top cover 2 under the upward pressing action of the spring 63.

[0030] The bottom cavity 101 houses the controller 17 and the battery. A remote control is matched with the controller 17. The servo motor 4 is electrically connected to the controller 17 and the battery.

[0031] In this embodiment, the controller 17 is an ESP8266. After a command is sent to the controller 17 via a remote control, the controller 17 can control the servo motor 4 to rotate the base plate 5 by a specified angle, thereby causing the top seat 7 and multiple sample bottles 9 to rotate by a specified angle. The battery can power the controller 17 and the servo motor 4.

[0032] The top of the through hole 141 is threaded and connected to a second locking bolt 142. Multiple crossbars 15 can be screwed into the threaded grooves of adjacent crossbars 15 through the threaded head 16, which can realize the splicing of multiple crossbars 15. According to the sampling position, crossbars 15 of appropriate length are spliced, and then the spliced ​​crossbars 15 are inserted into the through hole 141. Then, the second locking bolt 142 is tightened to compress the crossbars 15 and fix them.

[0033] Working principle: First, multiple crossbars 15 are spliced ​​together. Then, the crossbars 15 are inserted into the through holes 141 and the second locking bolts 142 are tightened to compress and fix the crossbars 15. Then, the reel 12 is rotated to unwind the wire rope 13. The wire rope 13 drives the top cover 2 and the sampling cylinder 1 to descend into the water. At this time, the remote control sends a command to the controller 17. The controller 17 controls the servo motor 4 to drive the base plate 5 to rotate by a specified angle, so that one of the sample bottles 9 rotates to below the inlet 21. Water will enter the sample bottle 9 from the inlet 21. Then, the servo motor 4 is controlled to drive the base plate 5 to continue to rotate by a specified angle, so that the inlet 21 is located between two sample bottles 9. At this time, the upper surface of the top seat 7 between the two adjacent positioning slots 8 closes the inlet 21. Then continue to rotate the reel 12 to make the sampling cylinder 1 descend to different depths. When the sampling cylinder 1 descends to another depth, continue to control the servo motor 4 to drive the base plate 5 to rotate, so that another sample bottle 9 rotates to the bottom of the inlet 21 for sampling, until all the sample bottles 9 are filled with water samples.
