Description

Technical Field

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

[0002] Water quality monitoring is a crucial link in ensuring ecological security and human health. By analyzing water samples, we can understand indicators such as pollutant distribution and nutrient content, providing data support for water pollution control and ecological restoration.

[0003] However, most current water quality monitoring sampling devices adopt a fixed length design. The fixed length design is difficult to adapt to the stratification characteristics of water bodies at different depths. In natural water bodies, the water quality at different depths varies significantly due to factors such as light, temperature, and microbial activity. Fixed-length sampling devices can only obtain samples from a single depth at a time, making it inconvenient to sample water from different depth layers, which may lead to the omission of key pollution information.

[0004] In view of this, this application proposes a sampling device for water quality environmental monitoring to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a sampling device for water quality monitoring. This device adjusts the length of the rubber tube submerged in water by sliding a float, uses a limiting sleeve for positioning, and utilizes the combined force of a counterweight sinker and the buoyancy of the float to suspend the counterweight sinker at the target water layer. A water pump is then activated to draw water through a side inlet and discharge it through an outlet pipe, enabling rapid collection of water samples from different water layers. The device is simple in structure and low in cost, thus solving the problems mentioned in the background section.

[0006] A sampling device for water quality environmental monitoring includes: a sampling structure comprising a water pump, a rubber tube on one side of the water pump, a counterweight countersunk head installed at the lower end of the rubber tube, the lower end of the counterweight countersunk head being a conical structure, and a set of side water inlets on both sides thereof; a float ball slidably mounted on the rubber tube, and two sets of limiting rubber sleeves fitted around the outside of the rubber tube on each of the upper and lower sides of the float ball; and a winding structure comprising a fixed cylinder disposed at the front end of the water pump, the rubber tube being wound around the outside of the fixed cylinder, a fixed circular plate installed at the rear end of the fixed cylinder, and a limiting ring disposed at the front end of the fixed cylinder, which can slide back and forth to limit the movement of the wound rubber tube.

[0007] In a preferred embodiment, a filter screen is installed inside the side water inlet, and both sets of side water inlets are connected to the inside of the rubber tube.

[0008] In a preferred embodiment, one end of the rubber tube is connected to the water pump's inlet, and an outlet pipe is installed on the water pump's inlet.

[0009] In a preferred embodiment, a base is installed below the water pump, and a handle is installed above it.

[0010] In a preferred embodiment, the fixed circular plate is connected to the water pump, the limiting ring is located outside the fixed cylinder, and the diameter of the limiting ring is the same as the diameter of the fixed circular plate.

[0011] In a preferred embodiment, a threaded rod is installed in the middle of the inside of the fixed cylinder, and an inner circular plate is provided inside the fixed cylinder, with the threaded rod threadedly connected to the center of the inner circular plate.

[0012] In a preferred embodiment, a set of guide grooves are respectively provided on both sides of the fixed cylinder, and a slider is slidably provided in the guide groove. The upper end of the slider is connected to the limiting ring, and its lower end is connected to the inner circular plate.

[0013] In a preferred embodiment, the front end of the threaded rod is connected to a rotating head through the fixed cylinder.

[0014] Beneficial effects:

[0015] 1. By designing a sampling structure, users can freely slide the float along the outside of the rubber tube to adjust its position according to the target sampling depth, precisely controlling the length of the rubber tube entering the water. After adjustment, the float is limited on both the upper and lower sides by limiting sleeves, and the positioning is achieved through the frictional resistance of the tight fit. Then, the counterweight head is thrown into the water, and its gravity pulls the rubber tube to sink vertically, while the float floats stably on the water surface by its own buoyancy, ensuring that the counterweight head is suspended at the target water layer. At this time, the water pump is started, and the water quickly enters the rubber tube through the side inlet. Then, under the action of the water pump, the water is discharged through the outlet pipe to achieve sampling. This design can quickly collect water samples from different water layers, is simple and convenient to operate, has a simple structure, low manufacturing cost, and significantly improves the flexibility of water quality sampling.

[0016] 2. By designing a winding structure, the rubber tube can be tightly wound around the outside of the fixed cylinder before carrying. Then, the threaded rod is rotated to drive the inner circular plate to move axially, which in turn drives the limiting ring connected to it to move synchronously towards the fixed circular plate. As the threaded rod continues to rotate, the distance between the limiting ring and the fixed circular plate decreases, forming a bidirectional clamping force on the wound rubber tube. The stability characteristics of mechanical transmission are used to clamp and fix the rubber tube, avoiding loosening due to shaking or squeezing. This structure not only ensures compact storage but also enhances stability during carrying. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 As shown, a sampling device for water quality environmental monitoring includes: a sampling structure 1, including a water pump 11, a rubber tube 14 on one side of the water pump 11, a counterweight sinker 17 installed at the lower end of the rubber tube 14, and the lower end of the counterweight sinker 17 is a conical structure with a set of side water inlets 19 on both sides, a float ball 15 slidingly mounted on the rubber tube 14, and two sets of limiting rubber sleeves 16 fitted on the outside of the rubber tube 14 on the upper and lower sides of the float ball 15; and a winding structure 2, including a fixed cylinder 23 set at the front end of the water pump 11, the rubber tube 14 wound around the outside of the fixed cylinder 23, a fixed circular plate 22 installed at the rear end of the fixed cylinder 23, and a limiting ring 21 that can slide back and forth to limit the winding rubber tube 14.

[0025] Please see Figure 1 and Figure 3 As shown, a filter screen 110 is installed inside the side water inlet 19, and both sets of side water inlets 19 are connected to the inside of the rubber tube 14.

[0026] Please see Figures 1-2As shown, one end of the rubber hose 14 is connected to the water inlet of the water pump 11, and the water outlet pipe 18 is installed on the water inlet of the water pump 11.

[0027] Please see Figures 1-2 As shown, a base 12 is installed below the water pump 11, and a handle 13 is installed above it.

[0028] Please see Figures 1-2 As shown, the fixed circular plate 22 is connected to the water pump 11, and the limiting ring 21 is located outside the fixed cylinder 23, and the diameter of the limiting ring 21 is the same as the diameter of the fixed circular plate 22.

[0029] Please see Figures 4-5 As shown, a threaded rod 26 is installed in the middle of the inside of the fixed cylinder 23, and an inner circular plate 25 is provided inside the fixed cylinder 23, with the threaded rod 26 being threadedly connected to the center of the inner circular plate 25.

[0030] Please see Figures 4-5 As shown, a set of guide grooves 27 are respectively opened on both sides of the fixed cylinder 23, and a slider 28 is slidably arranged in the guide groove 27. The upper end of the slider 28 is connected to the limiting ring 21, and its lower end is connected to the inner circular plate 25. When the inner circular plate 25 moves, it can drive the slider 28 to move linearly along the path of the guide groove 27, thereby driving the limiting ring 21 to move stably.

[0031] Please see Figure 1 , Figure 2 as well as Figure 5 As shown, the front end of the threaded rod 26 passes through the fixed cylinder 23 and is connected to the screw head 24.

[0032] In practical use, the working principle of this utility model is as follows:

[0033] In use, first, adjust the position of the float 15 by sliding it along the outside of the rubber tube 14 according to the target sampling depth to control the length of the rubber tube 14 in the water. During the adjustment, adjust the limiting sleeve 16 outside the rubber tube 14 to move it away from the float 15. After the adjustment is in place, move the upper and lower sets of limiting sleeves 16 closer to the upper and lower sides of the float 15. Use the frictional resistance generated by the limiting sleeves 16 and the rubber tube 14 to position the float 15. Then, throw the counterweight sinker 17 into the water. In the process, the conical structure at the lower end of the counterweight sinker 17 can reduce the water inlet resistance. The counterweight sinker 17 uses its gravity to pull the rubber tube 14 to sink vertically, while the float 15 floats stably on the water surface by buoyancy, ensuring that the counterweight sinker 17 is suspended in the target water layer. Then, the water pump 11 is started, and the water enters the rubber tube 14 after being filtered by the side water inlets 19 of the filter screens 110 on both sides of the counterweight sinker 17. Then, it is transmitted to the outlet pipe 18 by the water pump 11 to complete the water sample collection of the target water layer.

[0034] When carrying the device, the rubber tube 14 is tightly wound around the outside of the fixed cylinder 23. The screw head 24 drives the threaded rod 26 to rotate, and the inner circular plate 25 is driven to move axially through the threaded transmission, which drives the slider 28 to move along the guide groove 27. This causes the limiting ring 21 to move towards the fixed circular plate 22. As the threaded rod 26 continues to rotate, the distance between the limiting ring 21 and the fixed circular plate 22 continuously decreases, forming a bidirectional clamping force on the wound rubber tube 14, clamping and fixing it to prevent the rubber tube 14 from loosening during carrying. Then, the water pump 11 can be lifted by the handle 13 to carry the device.
