Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, specifically a convenient water quality testing and sampling device. Background Technology

[0002] In the field of water quality environmental monitoring, water quality testing devices are widely used and play a vital role in environmental protection, water quality detection, and water resource protection. The scope of water quality monitoring is very broad, including routine surface and groundwater monitoring, surveillance of production and domestic processes, and emergency accident monitoring. Water quality monitoring provides data and information for environmental management and serves as a basis for evaluating the condition of rivers and oceans. Therefore, water quality testing typically requires the use of sampling devices to collect water samples for subsequent testing.

[0003] For example, Chinese patent application CN201620384900.5 discloses a portable shallow water sampling device, which includes a water gun, a piston assembly, and a sampling bottle. The piston assembly is inserted into the water gun, and the sampling bottle is positioned below the water gun. This device is convenient to use and has a simple structure, including a water gun, a sampling bottle, and a stopper that matches the sampling bottle. It mainly solves the problems of existing water sampling devices, such as difficulty in controlling the sampling depth, the bottle body disrupting the water flow field during sampling resulting in unrepresentative test results, complex structure, high cost, and inconvenience in carrying.

[0004] However, in actual use, when the above-mentioned device is applied to water quality sampling in environments such as rivers, aquatic plants or mud are easily adsorbed onto the water sampling nozzle, causing blockage of the water sampling nozzle and affecting the water quality sampling effect, resulting in poor performance. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a convenient water quality testing and sampling device. An arc-shaped plate drives several blocking rods to rotate simultaneously around the sampling cylinder, isolating aquatic plants and sediment from the cylinder. Sampling is then achieved through several sampling holes, thus avoiding sampling blockage, ensuring more representative water quality samples, reducing sample pretreatment steps, and guaranteeing the smooth progress of the water quality sampling process. This effectively solves the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a convenient water quality testing and sampling device, including a main support frame, wherein a U-shaped handle is fixedly provided at the top of one end of the main support frame;

[0007] The other end of the main support frame is equipped with an adjustment component for sampling water quality in target water areas with different water depths and distances from the shore.

[0008] A sampling component is provided at the bottom of the other end of the main support frame to ensure the smooth progress of the water sampling process;

[0009] The sampling assembly includes a fixed cylinder located at the bottom of the other end of the main support frame. The bottom of the fixed cylinder is connected to a rotating shaft via a bearing. A sampling cylinder is located at the bottom of the rotating shaft. A disc is fixed on the rotating shaft. Arc-shaped plates are fixed on both sides of the bottom of the disc. Several evenly distributed blocking rods are fixed on the side of the arc-shaped plate away from the sampling cylinder to facilitate the isolation of aquatic plants and silt from the sampling cylinder.

[0010] Preferably, the top of the sampling tube is connected to a threaded cap by a thread, and a connecting rod is fixedly provided at the center of the top of the threaded cap. The top of the connecting rod is connected to the bottom of the rotating shaft by a bearing. The disc is located at the bottom of the fixed tube, which makes it easy to twist the sampling tube, remove it, and take out the water sample.

[0011] Preferably, the top of the sampling cylinder has several evenly distributed sampling holes, and a motor is fixedly installed inside the fixed cylinder. The output shaft of the motor passes through the bottom of the fixed cylinder and is fixedly connected to the top of the rotating shaft, so as to facilitate the motor to drive the rotating shaft to rotate.

[0012] Preferably, the adjusting component includes a threaded rod, the two ends of which are connected to the two ends inside the main support frame via bearings. A threaded block is threadedly connected to the threaded rod. A U-shaped connecting rod is fixedly provided on the top and bottom of one side of the threaded block. The two U-shaped connecting rods pass through the top and bottom of the other end of the main support frame, respectively. The same extension rod is fixedly provided between the ends of the two U-shaped connecting rods away from the threaded block, so that the threaded block can move horizontally along the threaded rod, thereby driving the U-shaped connecting rod and the extension rod to move horizontally.

[0013] Preferably, the front and rear sides of the end of the extension rod away from the U-shaped connecting rod are connected by a bearing to the same rotating rod. The front end of the rotating rod passes through the front side of the extension rod and is fixedly provided with a turntable. A connecting seat is fixedly provided on the rotating rod, and the connecting seat is located at the end of the extension rod away from the U-shaped connecting rod, so as to facilitate the rotation of the rotating rod to drive the connecting seat to rotate.

[0014] Preferably, one end of the main support frame is connected to a crank handle via a bearing. One end of the crank handle passes through one side of the main support frame and is fixedly connected to one end of a threaded rod. Both the crank handle and the turntable are threadedly connected with bolts for fixing the crank handle and the main support frame, and the turntable and the extension rod, respectively. This makes it easy to tighten one bolt to fix the crank handle and the main support frame, and easy to tighten the other bolt to fix the turntable and the extension rod.

[0015] Preferably, a telescopic rod is fixedly provided at the bottom of the connecting seat, and a fixed cylinder is fixedly provided at the bottom end of the telescopic rod, which facilitates driving the fixed cylinder to move.

[0016] Compared with the prior art, this utility model provides a convenient water quality testing and sampling device, which has the following beneficial effects:

[0017] 1. This utility model uses a motor-driven rotating shaft to rotate a disc and an arc-shaped plate. The arc-shaped plate then rotates several blocking rods around the sampling cylinder simultaneously, isolating aquatic plants and sediment from the sampling cylinder. This prevents aquatic plants and sediment from clogging the sampling holes, allowing the sampled water to flow into the sampling cylinder through the sampling holes. Finally, the sampling cylinder is unscrewed from the bottom of the threaded cap to collect water samples. This method avoids sampling blockage, ensures that the collected water is more representative, reduces sample pretreatment steps, and guarantees the smooth progress of the water sampling process.

[0018] 2. This utility model adjusts the distance between the main support frame and the extension rod, then rotates the turntable to drive the rotating rod and connecting seat to rotate around the front end of the extension rod, adjusts the appropriate angle, and then adjusts the length of the telescopic rod, thereby facilitating accurate access to target water areas with different water depths and distances from the shore. This ensures that spatially representative water samples can be collected safely and efficiently even in complex terrain, while avoiding the risk of personnel directly wading into the water, significantly improving the adaptability of the sampling range and the safety of operation.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-5 As shown, this utility model provides a convenient water quality testing and sampling device, including a main support frame 1, and a U-shaped handle 5 is fixedly provided at the top of one end of the main support frame 1.

[0028] like Figure 1-4 As shown, a sampling component 3 is provided at the bottom of the other end of the main support frame 1 to ensure the smooth progress of the water quality sampling process. The sampling component 3 includes a fixed cylinder 31, which is located at the bottom of the other end of the main support frame 1. A rotating shaft 33 is connected to the bottom of the fixed cylinder 31 through a bearing. A sampling cylinder 36 is provided at the bottom of the rotating shaft 33. A disc 32 is fixed on the rotating shaft 33. Arc plates 38 are fixed on both sides of the bottom of the disc 32. Several evenly distributed blocking rods 39 are fixed on the side of the arc plate 38 away from the sampling cylinder 36 to facilitate the isolation of aquatic plants and silt from the sampling cylinder 36.

[0029] The top of the sampling cylinder 36 is connected to a threaded cap 35 by a thread. A connecting rod 34 is fixedly provided at the center of the top of the threaded cap 35. The top of the connecting rod 34 is connected to the bottom of the rotating shaft 33 by a bearing. The disc 32 is located at the bottom of the fixed cylinder 31, which facilitates the unscrewing of the sampling cylinder 36 and its removal for easy water sample extraction. The top of the sampling cylinder 36 has several evenly distributed sampling holes 37. A motor 310 is fixedly provided inside the fixed cylinder 31. The output shaft of the motor 310 passes through the bottom of the fixed cylinder 31 and is fixedly connected to the top of the rotating shaft 33, which facilitates the motor 310 to drive the rotating shaft 33 to rotate.

[0030] By setting up the sampling component 3, when water quality sampling is required, the sampling tube 36 is submerged in the water. Then, the control panel 4 controls the motor 310 inside the fixed tube 31 to work. The motor 310 drives the rotating shaft 33 to rotate, which in turn drives the disc 32 and the arc plate 38 to rotate, causing the arc plate 38 to rotate around the sampling tube 36. At the same time, it drives several blocking rods 39 on the arc plate 38 to rotate around the sampling tube 36, isolating aquatic plants and silt from the sampling tube 36 and preventing them from clogging the sampling holes 37. This allows the water quality to flow into the sampling tube 36 through the sampling holes 37. Finally, the sampling tube 36 is unscrewed from the bottom of the threaded cap 35, thus enabling water quality sampling. This avoids sampling blockage, ensures that the collected water quality is more representative, reduces sample pretreatment steps, and ensures the smooth progress of the water quality sampling process.

[0031] like Figure 1-3As shown in Figure 5, the other end of the main support frame 1 is provided with an adjustment component 2 for water quality sampling of target water areas with different water depths and distances from the shore. The adjustment component 2 includes a threaded rod 21. The two ends of the threaded rod 21 are connected to the two ends inside the main support frame 1 through bearings. A threaded block 22 is threadedly connected to the threaded rod 21. A U-shaped connecting rod 23 is fixedly provided on the top and bottom of one side of the threaded block 22. The two U-shaped connecting rods 23 pass through the top and bottom of the other end of the main support frame 1, respectively. The same extension rod 24 is fixedly provided between the ends of the two U-shaped connecting rods 23 away from the threaded block 22, so that the threaded block 22 can move horizontally along the threaded rod 21 to drive the U-shaped connecting rod 23 and the extension rod 24 to move horizontally.

[0032] The extension rod 24, away from the U-shaped connecting rod 23, has a common rotating rod 25 connected to its front and rear sides via bearings. The front end of the rotating rod 25 passes through the front side of the extension rod 24 and is fixedly mounted on a turntable 27. A connecting seat 26 is fixedly mounted on the rotating rod 25, located at the end of the extension rod 24 away from the U-shaped connecting rod 23, facilitating rotation of the rotating rod 25 to drive the connecting seat 26 to rotate. One end of the main support frame 1 is connected to a crank handle 29 via a bearing. One end of the crank handle 29 passes through one side of the main support frame 1 and... The crank handle 29 and the turntable 27 are both fixedly connected to one end of the threaded rod 21. Bolts are threadedly connected to the crank handle 29 and the main support frame 1, and the turntable 27 and the extension rod 24, respectively. This makes it easy to tighten one bolt to fix the crank handle 29 and the main support frame 1, and easy to tighten the other bolt to fix the turntable 27 and the extension rod 24. The bottom of the connecting seat 26 is fixedly provided with a telescopic rod 28, and the fixed cylinder 31 is fixedly provided at the bottom end of the telescopic rod 28, which makes it easy to drive the fixed cylinder 31 to move.

[0033] By setting the adjustment component 2, according to the distance and depth between the staff and the target water area, the bolts on the crank handle 29 and the turntable 27 are loosened respectively. The crank handle 29 is manually turned to drive the threaded rod 21 to rotate. The rotation of the threaded rod 21 causes the threaded block 22 on it to drive the U-shaped connecting rod 23 to move horizontally along the threaded rod 21, which makes it easy to expand the extension rod 24 from inside the main support frame 1. This facilitates the adjustment of the distance between the main support frame 1 and the extension rod 24. After adjustment, the bolts on the crank handle 29 are tightened to fix its overall length. Then, the turntable 27 is rotated to drive the rotating rod 25 and the connecting seat 26 to rotate around the front end of the extension rod 24. After adjusting the angle, the length of the telescopic rod 28 is adjusted, which facilitates accurate access to the target water area with different water depths and distances from the shore. This ensures that spatially representative water samples can be collected safely and efficiently even in complex terrain, while avoiding the risk of personnel directly wading into the water. This significantly improves the adaptability of the sampling range and the safety of operation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
