Description

Technical Field

[0001] This utility model relates to the field of environmental protection monitoring sampling technology, specifically a sampling device for environmental protection monitoring equipment. Background Technology

[0002] Environmental monitoring is the foundation for scientific environmental management and environmental law enforcement supervision. It is an essential basic task for environmental protection. The core objective of environmental monitoring is to provide data on the current status and trends of environmental quality, to assess environmental quality, to evaluate current major environmental problems, and to serve environmental management. Water sampling is an important basic component of environmental monitoring. However, in actual water sampling work, the quality of the work is often affected by many factors such as sampling technology, sampling tools, and sampling environment. This also affects the accuracy of environmental monitoring data to a certain extent. In particular, the sampling tools have a profound impact on the work efficiency of the sampling staff.

[0003] In existing water sampling devices, when sampling water from heavily polluted rivers and lakes with a lot of floating impurities, the lack of a clearing and debris removal component makes it easy for large debris such as plant branches and leaves and aquatic plants to be adsorbed and blocked at the water inlet, causing obstacles to the sampling water. In addition, small particulate impurities in the water can easily clog the filter screen at the water inlet, requiring staff to frequently remove the sampling container from the water and manually clean it, making the cleaning operation cumbersome, laborious and inconvenient. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a sampling device for environmental protection monitoring equipment to solve the technical problem that small particulate impurities in water easily clog the filter screen on the water inlet, requiring staff to frequently remove the sampling container from the water and manually brush and clean it, resulting in a cumbersome, laborious and inconvenient cleaning operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for environmental protection monitoring equipment, comprising a water cylinder, a fixing ring fixedly connected to the top of the outer wall of the water cylinder, a rubber stopper provided inside the water cylinder, a lead screw fixedly connected to the top of the rubber stopper, a first gear passing through the top of the lead screw, and a threaded groove on the inner wall of the first gear that meshes with the lead screw, a second gear meshing with the first gear on one side, a rotating shaft fixedly connected to the top of the second gear, a third gear at the bottom of the rotating shaft, a rotating ring rotatably connected to the outer side of the water cylinder, a fourth gear meshing with the third gear at the top of the rotating ring, a water inlet chamber fixedly connected to the top of the water cylinder, and four sets of filter screens evenly arranged on the outer wall of the water inlet chamber.

[0006] By adopting the above technical solution, the power is transferred through the meshing of the first and second gears. While the rotating shaft drives the rotating ring, it can also link with the first gear to control the screw and rubber plug to slide up and down to pump water. It is convenient to use. While the rotating ring is rotating, the linkage of the third and fourth gears drives four sets of brushes to clean the filter screen on the outer wall of the water inlet chamber, effectively reducing the chance of the filter screen being blocked by small floating debris. It also eliminates the trouble of manually pulling out the sampling water tube to manually brush and clean the blockage, reducing the workload of the staff and making the cleaning operation of the sampling water tube simple and quick.

[0007] Furthermore, a handle is fixedly connected to the top of the second gear, and a rubber ring is fixed to the outside of the handle.

[0008] By adopting the above technical solution, the handle serves to facilitate the rotation of the second gear.

[0009] Furthermore, the top of the water cylinder is fitted with an outer shell, and the top of the outer shell has an annular hole that mates with the handle.

[0010] By adopting the above technical solution, the outer shell plays a role in protecting the internal structure.

[0011] Furthermore, limit rings are provided at both the upper and lower ends of the first gear, and fixed rods are fixedly connected to both sides of the limit rings.

[0012] By adopting the above technical solution, the limiting ring plays the role of fixing the first gear.

[0013] Furthermore, a fixing block is fixedly connected to the outer wall of the water cylinder, and the rotating shaft passes through the fixing block.

[0014] By adopting the above technical solution, the fixing block plays the role of fixing the rotating shaft.

[0015] Furthermore, four sets of connecting blocks are evenly arranged at the bottom of the rotating ring, and a brush is provided on one side of each connecting block.

[0016] By adopting the above technical solution, the connecting block serves to fix the brush.

[0017] In summary, the present invention has the following advantages: The present invention transmits power through the meshing of the first gear and the second gear. While the rotating shaft drives the rotating ring, it can also link with the first gear to control the screw and the rubber plug to slide up and down to pump water. It is convenient to use. While the rotating ring is rotating, the linkage of the third gear and the fourth gear drives four sets of brushes to clean the filter screen on the outer wall of the water inlet chamber, which effectively reduces the chance of the filter screen being blocked by small floating debris. It also eliminates the trouble of manually pulling out the sampling water tube to manually brush and clean the blockage, reducing the workload of the staff and making the cleaning operation of the sampling water tube simple and quick.

Four sets of filter screens 15 are evenly arranged on the outer wall of the water inlet chamber 1. In use, the user can rotate the second gear 7 forward and backward by rotating the handle 8 to drive the first gear 5, thereby pushing the lead screw 4 and the rubber stopper 3 to slide up and down along the internal space of the sampling water cylinder 1 to draw water for sampling.

[0026] At the same time, the rotation of the rotating shaft 9 drives the third gear 18, which can mesh with and drive the fourth gear 19, thereby driving the rotating ring 11 to rotate. Under the rotation of the rotating ring 11, the four sets of brushes 13 brush and clean the four sets of filter screens 15.

[0027] It effectively reduces the chance of the filter screen 15 being clogged by small floating debris, and eliminates the hassle of manually pulling out the sampling water tube 1 to manually brush and clean the blockage, reducing the workload of the staff and making the cleaning operation of the sampling water tube 1 simple and quick.

[0028] Please see Figures 1-4 A handle 8 is fixedly connected to the top of the second gear 7, and a rubber ring is fixed to the outside of the handle 8. Through the above structure, the handle 8 serves to facilitate the rotation of the second gear 7.

[0029] Please see Figure 1 The top of the water tank 1 is fitted with a shell 17, and the top of the shell 17 has a circular hole that matches the handle 8. Through the above structure, the shell 17 plays the role of protecting the internal structure.

[0030] Please see Figure 2 , Figure 3 and Figure 4 The first gear 5 is provided with limit rings 6 at both the upper and lower ends. The limit rings 6 are fixedly connected to the two sides of the limit rods 16. In this utility model, the limit rings 6 play the role of fixing the first gear 5 through the above structure.
