Description

Technical Field

[0001] This utility model relates to the field of environmental governance technology, and in particular to a water quality sampling device for ecological environment governance. Background Technology

[0002] Ecological and environmental governance is a process of systematically intervening in natural ecosystems and environmental problems caused by human activities, with the goal of improving and protecting the ecological environment, through policy guidance, technological means, and public participation. It encompasses multiple fields such as the atmosphere, water, soil, and biodiversity, aiming to reduce pollution emissions, restore damaged ecosystems, and rationally utilize resources. For water pollution detection, water quality sampling devices are required.

[0003] In the prior art, such as Chinese Patent No. CN221707005U, a water quality testing sampling mechanism is disclosed, specifically relating to the field of sampling mechanism technology. It includes a water-collecting cylinder and a telescopic rod. The telescopic rod is detachably installed at the top of the water-collecting cylinder. An inlet is provided at the upper middle part of the outer wall of the water-collecting cylinder, and a filter screen is provided at the inlet. The upper part of the inlet is provided with opposing first and second arc-shaped baffles for blocking the filter screen. The first and second arc-shaped baffles can move closer or further apart through the movable structure. This utility model features a conical sealing component, which facilitates the water-collecting cylinder entering the water-collecting area through weeds. The detachably connected filter screen effectively blocks weeds from entering the water-collecting cylinder, ensuring sufficient water intake and eliminating the need for subsequent cleaning of weeds. Furthermore, the first and second cutting sections are used to cut vines and weeds in the water.

[0004] While the above-mentioned scheme has the advantages mentioned above, its disadvantages are as follows: Although it can effectively prevent weeds and other organisms from entering the water collection tube by using a filter screen, thus ensuring the water intake and eliminating the need for subsequent cleaning of weeds and other organisms in the water collection tube, and the first and second cutting sections are designed to cut vines and weeds in the water, making it easier for the water collection tube to quickly penetrate into eutrophic water, the process of sampling the water area requires staff to hold the sampling device close to the edge of the water area. For complex water edges, there is an unpredictable danger, resulting in low safety for staff when sampling water quality. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. While these technologies can effectively prevent weeds and other debris from entering the water collection tube using a filter screen, thus ensuring sufficient water intake and eliminating the need for subsequent cleaning of the tube, and while the first and second cutting sections are designed to cut vines and weeds in the water, facilitating the rapid penetration of the water collection tube into eutrophic water, the sampling process requires workers to hold the sampling device close to the edge of the water body. This poses a risk due to the unpredictable dangers at complex water edges, resulting in low safety for workers during water sampling.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a water quality sampling mechanism for ecological environment governance, comprising: an upper sampling cylinder, a lower sampling cylinder threadedly connected to the bottom of the upper sampling cylinder, two symmetrical arc-shaped grooves on the outer surface of the upper sampling cylinder, a movable disk slidably connected inside the upper sampling cylinder, a movable rod fixedly connected to the top of the movable disk, a fixed ring fixedly connected to the inner wall of the upper sampling cylinder, a spring provided on the outer surface of the movable rod, a fixed block fixedly connected to the outer surface of the upper sampling cylinder near the top, and a counterweight column fixedly connected to the bottom of the lower sampling cylinder.

[0007] Preferably, one end of the spring is fixedly connected to the bottom of the fixed ring, and the other end of the spring is fixedly connected to the bottom of the movable disc.

[0008] Preferably, the movable rod is in a sealed sliding connection with the fixed ring, and the movable rod is in a sealed sliding connection with the upper sampling cylinder.

[0009] Preferably, the outer surface of the movable rod has a circular hole one, and the top of the fixed block has a circular hole two.

[0010] Preferably, a filter screen is detachably installed on the inner wall of the arc-shaped groove, and both arc-shaped grooves are connected to the upper sampling cylinder.

[0011] Preferably, the outer surface of the upper sampling tube is fixedly connected with a plurality of cutting blades in a circumferential array, and the outer surface of the lower sampling tube is fixedly connected with a plurality of cutting blades in a circumferential array.

[0012] Preferably, the movable plate is made of rubber.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 0. This utility model involves throwing the device into a water area far from weeds using a rope. With the help of the counterweight, the device sinks into the water. Then, by pulling the rope connected to the first circular hole, a pulling force is applied to the movable rod, causing it to slide upwards along the inside of the upper sampling tube. Simultaneously, the movable disc slides upwards along the inside of the upper sampling tube, moving away from the position of the arc-shaped groove. At the same time, the spring is compressed. At this time, water in the water enters the upper and lower sampling tubes through the arc-shaped groove and is filtered by the filter screen to block weeds and algae in the water. Then, the rope connected to the second circular hole is released, allowing the movable disc to slide downwards along the inside of the upper sampling tube under the restoring force of the spring, sealing the position of the arc-shaped groove. Finally, by pulling the rope connected to the second circular hole, the device can be pulled back from the water area. In this way, for complex and dangerous water areas, workers can take samples away from the water edge, thus ensuring the safety of workers taking water samples.

[0014] 1. In this utility model, when the device passes through weeds during the pull-back process, the weeds can be cut by the action of cutting blade one and cutting blade two, so as to prevent the device from being entangled by weeds. In this way, the device can be easily pulled back from the water and avoid being entangled by weeds. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Examples, such as Figure 1 - Figure 4 As shown, this utility model provides a water quality sampling mechanism for ecological environment governance, including: an upper sampling cylinder 1, a lower sampling cylinder 4 threadedly connected to the bottom of the upper sampling cylinder 1, two symmetrical arc-shaped grooves 11 on the outer surface of the upper sampling cylinder 1, a movable disk 13 sealed and slidably connected inside the upper sampling cylinder 1, a movable rod 7 fixedly connected to the top of the movable disk 13, a fixed ring 12 fixedly connected to the inner wall of the upper sampling cylinder 1, a spring 14 provided on the outer surface of the movable rod 7, a fixed block 9 fixedly connected to the outer surface of the upper sampling cylinder 1 near the top, and a counterweight column 6 fixedly connected to the bottom of the lower sampling cylinder 4.

[0020] Furthermore, such as Figure 1 - Figure 4 As shown, one end of the spring 14 is fixedly connected to the bottom of the fixed ring 12, and the other end of the spring 14 is fixedly connected to the bottom of the movable disk 13. Under the reset force of the spring 14, a downward pushing force can be applied to the movable disk 13.

[0021] Furthermore, such as Figure 1 - Figure 4 As shown, the movable rod 7 is slidably connected to the fixed ring 12 and slidably connected to the upper sampling tube 1. Through the above settings, water can be prevented from entering the upper sampling tube 1.

[0022] Furthermore, such as Figure 1 - Figure 4 As shown, the outer surface of the movable rod 7 has a circular hole 8, and the top of the fixed block 9 has a circular hole 10. The circular holes 8 and 10 facilitate the connection of the rope between the movable rod 7 and the fixed block 9.

[0023] Furthermore, such as Figure 1 - Figure 4 As shown, a filter screen 3 is detachably installed on the inner wall of the arc-shaped groove 11. Both arc-shaped grooves 11 are connected to the upper sampling tube 1. The filter screen 3 facilitates the blocking and filtration of weeds and algae in the water.

[0024] Furthermore, such as Figure 1 - Figure 4As shown, the outer surface of the upper sampling tube 1 is fixedly connected with multiple cutting blades 1 2 in a circumferential array, and the outer surface of the lower sampling tube 4 is fixedly connected with multiple cutting blades 2 5 in a circumferential array. Under the action of the cutting blades 1 2 and the cutting blades 2 5, weeds can be cut, thus preventing the device from being entangled by weeds.

[0025] Furthermore, such as Figure 1 - Figure 4 As shown, the movable plate 13 is made of rubber, and through the above-mentioned settings, it achieves a certain sealing effect.

[0026] Working principle: In use, two ropes are connected to the first hole 8 and the second hole 10 respectively. When using this device for sampling, it can be thrown away from the edge of the water area. With the help of the weight of the counterweight column 6, the device sinks into the water. Then, pull the rope connected to the first hole 8 to apply a pulling force to the movable rod 7, causing the movable rod 7 to slide upward along the inside of the upper sampling tube 1. At the same time, the movable plate 13 slides upward along the inside of the upper sampling tube 1 and moves away from the position of the arc groove 11. Simultaneously, the spring 14 is compressed. At this time, the water in the water enters the upper sampling tube 1 and the lower sampling tube 4 through the arc groove 11, and passes through the filter screen 3 to filter out weeds and algae in the water. After filtering, the rope connecting the second round hole 10 is loosened, allowing the movable disc 13 to slide downwards along the inside of the upper sampling tube 1 under the restoring force of the spring 14, sealing the position of the arc-shaped groove 11. Then, by pulling the rope connecting the second round hole 10, the device can be pulled back from the water area. This allows staff to take samples away from the edge of complex and dangerous water areas, ensuring the safety of water quality sampling. When the device passes through weeds during the pull-back process, the weeds can be cut by the action of the first cutting disc 2 and the second cutting disc 5, preventing the device from being entangled in weeds. This makes it easy to pull the device back from the water area, avoiding the situation of being entangled in weeds.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
