Description

Technical Field

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

[0002] Water sampling refers to collecting water samples from a water body and analyzing them to obtain basic data on water pollution. Currently, water monitoring mainly relies on manual sampling followed by laboratory analysis, which is time-consuming and cannot provide real-time data. With increasingly stringent environmental regulations, the frequency and real-time requirements for monitoring water pollutants have significantly increased, and traditional technologies are no longer sufficient to meet these demands.

[0003] The existing patent (publication number: CN115326491B) discloses the drawbacks of existing water sampling devices, such as the inability to adjust the water sampling depth and the inconvenience of water sample extraction. This patent provides a stratified water sampler for water environment testing, belonging to the technical field of water sampling devices. It includes a vertical pipe with an air vent and a track. Multiple longitudinally distributed water sampling containers are detachably mounted on the vertical pipe, each with a fixed air vent. Each water sampling container also has a water inlet with a first valve. A flexible hose is detachably connected to the outer end of the water inlet, and a water inlet head slidably mounted on the track is connected to the hose. The water inlet head has a second valve. A transmission mechanism is also provided on the vertical pipe. An air outlet is also provided on the vertical pipe, higher than all the water sampling containers and the water inlet head.

[0004] In recent years, most automated sampling devices have focused on a single function. The separation of sampling and detection leads to low efficiency and requires manual sample transfer, which poses a risk of cross-contamination. Therefore, a water sampling and detection device is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a water sampling and testing device that integrates water sampling and testing, improving the convenience and efficiency of water sampling and testing. It solves the problems mentioned in the aforementioned prior art, such as sampling devices being concentrated on a single function, separation of sampling and testing leading to low efficiency, and the need for manual sample transport posing a risk of cross-contamination.

[0006] To achieve the above objectives, this application provides the following technical solution: a water sampling and detection device, comprising a sampling box, a detection box disposed on the top of the sampling box, a sampling device disposed inside the sampling box, a sampling tube threadedly connected to one end of the sampling device, a pushing device disposed inside the sampling box, one end of the pushing device threadedly connected to the sampling tube, a diversion pipe connected to the output end of the sampling device, a sampling chamber connected to the top of the diversion pipe, a driving device disposed inside the sampling box, a displacement mechanism threadedly connected to the output end of the driving device, a detection mechanism slidably connected to one side of the displacement mechanism, and a limit wedge fixedly connected inside the sampling box.

[0007] The above solution connects the output of the pushing device to the external extension of the sampling tube. The pushing device drives the sampling tube to automatically extend to the water sampling location. The sampling device provides driving force to the sampling tube, allowing it to quickly transport water from the water body to one side of the diversion pipe and finally into the sampling chamber. The driving device drives the displacement mechanism to move so that the detection mechanism can automatically move to the detection position in the sampling chamber and enter the sampling chamber for detection with the help of the limiting wedge. This integration of water sampling and detection improves the convenience and efficiency of water sampling and detection.

[0008] Furthermore, the sampling device includes a sampling impeller pump, an input pipe is provided at the input end of the sampling impeller pump, one end of the input pipe is threadedly connected to the sampling pipe, and an output pipe is provided at the top of the sampling impeller pump, the output pipe being connected to the interior of the diversion pipe.

[0009] The above scheme utilizes a sampling impeller pump to generate internal suction force, which, in conjunction with the connection between the input pipe and the sampling pipe, allows the sampling pipe to draw water from the water area into the diversion pipe, and finally into the sampling chamber for storage. This provides the driving force for water sampling, enabling the rapid acquisition of water samples for testing.

[0010] Furthermore, the sampling chambers are provided in two sets, and the bottom of both sets of sampling chambers is connected to an upper passage pipe, the upper passage pipe being equipped with a check valve.

[0011] The above scheme, by installing check valves on the upper pipe, allows for the collection and storage of different water samples in a sampling chamber on the other side when it is necessary to sample other water bodies. This is achieved by closing one set of check valves and using a diversion pipe to transport the different water samples to the sampling chamber on the other side.

[0012] Furthermore, the pushing device includes a hydraulic cylinder, the output end of which is provided with a pushing rod, and one end of the pushing rod is fixedly installed with a connecting pushing plate, which is connected to the external thread of the sampling tube.

[0013] The above scheme connects the push plate to the outside of the sampling tube. When the hydraulic cylinder is activated, it pushes the push rod to extend and retract, thereby extending the sampling tube to automatically extend to the required sampling area, so as to facilitate rapid sampling of the water body.

[0014] Furthermore, the driving device includes a drive motor, an output screw is fixedly installed at the output end of the drive motor, the displacement mechanism includes a displacement block, a spring is fixedly connected to the top of the displacement block, the top of the spring is connected to the inner wall of the detection mechanism, and the detection mechanism is slidably connected to the outside of the displacement block.

[0015] The above scheme involves starting the drive motor to drive the output screw to rotate, thereby driving the displacement block to move laterally and moving the detection mechanism together. This provides displacement driving force to the detection mechanism, allowing it to automatically approach the sampling chamber.

[0016] Furthermore, the detection mechanism includes a detection probe, a housing is fixedly connected to the top of the detection probe, a slider is fixedly installed on the back of the housing, the slider is slidably connected to the outside of the displacement block, and a second wedge is fixedly installed on one side of the housing.

[0017] With the above scheme, when the displacement block moves, it drives the housing to move until it moves close to the limit wedge. Then, the second wedge continues to move and contacts the limit wedge, where it is pushed and restricted. Through the elastic extension and contraction of the spring, the slider is pushed to move the housing downward, so that the detection probe at the bottom can extend into the water sample in the sampling chamber for detection. The sensor set inside the housing and the detection box simultaneously record the water detection data. This integrates water sampling and detection, enabling fast and efficient sampling and recording of water samples.

[0018] Furthermore, the bottom of the sampling box is provided with wheels, and the number of wheels is set to several sets.

[0019] The above solution, with the addition of wheels, enables the sampling box to be movable, making its use more flexible.

[0020] Furthermore, a positioning frame is provided inside the sampling box, and the hydraulic cylinder is located inside the positioning frame.

[0021] With the above solution, the positioning frame is located at the bottom inside the sampling box, which facilitates the positioning and fixing of the hydraulic cylinder.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This water sampling and detection device connects the output end of a pushing device to the external extension end of a sampling tube. Driven by the pushing device, the sampling tube automatically extends towards the water sampling location. The sampling device provides driving force to the sampling tube, rapidly transporting water from the body to one side of a diversion pipe and ultimately into the sampling chamber. A displacement mechanism is driven by the driving device to automatically move the detection mechanism to the detection position within the sampling chamber and, with the help of a limiting wedge, enters the chamber for detection. This integrated approach combines water sampling and detection, improving the convenience and efficiency of water sampling and detection. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of a water sampling and detection device includes a sampling box 1, a detection box 2 on top of the sampling box 1, a sampling device 3 inside the sampling box 1, a sampling tube 4 threadedly connected to one end of the sampling device 3, a pushing device 5 inside the sampling box 1, one end of the pushing device 5 threadedly connected to the sampling tube 4, a diversion pipe 6 connected to the output end of the sampling device 3, a sampling chamber 7 connected to the top of the diversion pipe 6, a driving device 8 inside the sampling box 1, a displacement mechanism 9 threadedly connected to the output end of the driving device 8, a detection mechanism 10 slidably connected to one side of the displacement mechanism 9, and a limit wedge 11 fixedly connected inside the sampling box 1. The output end of the pushing device 5 is connected to the external extension end of the sampling tube 4. Through the driving action of the pushing device 5, the sampling tube 4 can automatically extend and expand towards the water sampling position. In conjunction with the sampling device 3, the sampling tube 4 can be driven to quickly transport the water in the water body to one side of the diversion pipe 6 and finally to the interior of the sampling chamber 7. The displacement mechanism 9 is driven by the driving device 8 to move so that the detection mechanism 10 can automatically move to the detection position of the sampling chamber 7 and enter the interior of the sampling chamber 7 for detection in conjunction with the limiting wedge 11. This combination integrates water sampling and detection, improving the convenience and efficiency of water sampling and detection.

[0032] Please see Figure 2 and Figure 3 The sampling device 3 includes a sampling impeller pump 301. An input pipe 302 is provided at the input end of the sampling impeller pump 301, and one end of the input pipe 302 is threadedly connected to the sampling pipe 4. An output pipe 303 is provided at the top of the sampling impeller pump 301, and the output pipe 303 is connected to the interior of the diversion pipe 6. The pushing device 5 includes a hydraulic cylinder 501. A pushing rod 502 is provided at the output end of the hydraulic cylinder 501. A connecting push plate 503 is fixedly installed at one end of the pushing rod 502, and the connecting push plate 503 is threadedly connected to the exterior of the sampling pipe 4. By activating the sampling impeller pump 301, a suction force is generated inside, which, in conjunction with the connection between the input pipe 302 and the sampling pipe 4, allows the sampling pipe 4 to draw water from the water area into the interior of the diversion pipe 6, and finally into the interior of the sampling chamber 7 for storage, thus providing driving force for water sampling. It can quickly obtain water samples for testing. By connecting the push plate 503 to the outside of the sampling tube 4, when the hydraulic cylinder 501 is activated, the push rod 502 is pushed to extend and retract, thereby pushing the sampling tube 4 to extend and retract, so that it automatically extends to the required sampling area, so as to facilitate rapid sampling of the water.

[0033] Please see Figure 3 and Figure 4The driving device 8 includes a drive motor 801, and an output screw 802 is fixedly installed at the output end of the drive motor 801. The displacement mechanism 9 includes a displacement block 901, and a spring 902 is fixedly connected to the top of the displacement block 901. The top of the spring 902 is connected to the inner wall of the detection mechanism 10. The detection mechanism 10 is slidably connected to the outside of the displacement block 901. By starting the drive motor 801, the output screw 802 is driven to rotate, thereby driving the displacement block 901 to move laterally, so as to drive the detection mechanism 10 to move together, providing displacement driving force for the detection mechanism 10, so that it automatically approaches the sampling chamber 7.

[0034] Please see Figure 4 and Figure 5 The detection mechanism 10 includes a detection probe 1011. A housing 1012 is fixedly connected to the top of the detection probe 1011. A slider 1013 is fixedly installed on the back of the housing 1012. The slider 1013 is slidably connected to the outside of the displacement block 901. A second wedge 1014 is fixedly installed on one side of the housing 1012. When the displacement block 901 moves, it drives the housing 1012 to move until it moves close to the limit wedge 11. After it continues to move, the second wedge 1014 contacts the limit wedge 11 and is pushed and restricted. Through the elastic extension and contraction of the spring 902, the slider 1013 is pushed to drive the housing 1012 to move downward, so that the detection probe 1011 at the bottom extends into the water sample of the sampling chamber 7 for detection. It also works with the sensor set inside the housing 1012 to synchronously record the water detection data with the detection box 2. This integrates water sampling and detection, enabling rapid and efficient sampling and recording of water samples.

[0035] This embodiment of a water sampling and detection device utilizes a hydraulic cylinder 501 to drive and extend / retract a push rod 502, enabling the sampling tube 4 to automatically extend and retract. In conjunction with a sampling impeller pump 301 and an input pipe 302, the sampling tube 4 rapidly draws water from the water area into a diversion pipe 6, ultimately storing it in a sampling chamber 7, achieving rapid sampling. The drive motor 801 and output screw 802 provide driving force to the drive displacement block 901, indirectly providing displacement driving force to the housing 1012. This causes the detection probe 1011 to automatically approach the sampling chamber 7, and, with the help of the limiting wedge 11 and the second wedge 1014, pushes the housing 1012 to slide downwards into the water in the sampling chamber 7 for detection. After detection, the displacement block 901 reverses its movement, causing the detection probe 1011 to automatically rise and reset. This integrated approach combines water sampling and detection, improving both sampling and detection efficiency.

[0036] The working principle of the above embodiments is as follows:

[0037] By connecting the push plate 503 to the outside of the sampling tube 4, when the hydraulic cylinder 501 is activated, the push rod 502 is pushed to extend and retract, thereby pushing the sampling tube 4 to extend and retract, so that it automatically extends to the required sampling area. The sampling impeller pump 301 is activated to generate a suction force inside, which works with the input pipe 302 and the sampling tube 4 to draw water from the water area into the diversion pipe 6, and finally input into the sampling chamber 7 for storage. The drive motor 801 is activated to drive the output screw 802 to rotate, thereby driving the displacement block 901 to move laterally. When the displacement block 901 moves, it drives the housing 1012 to move until it moves close to the limit wedge 11. Then, it continues to move. The second wedge 1014 contacts the limit wedge 11 and is pushed and restricted. Through the elastic extension and retraction of the spring 902, the slider 1013 is pushed to move the housing 1012 downward, so that the detection probe 1011 penetrates into the sampling chamber 7. Together with the sensor and detection box 2 inside the housing 1012, the water data is recorded.
