[0034] Such as Figures 1 to 5As shown, a drinking water quality sampling and detection device provided by an embodiment of the utility model includes a sampling body 1; a water pump 2 is fixedly connected to the top of the sampling body 1, a hose 3 is fixedly connected to the input end of the water pump 2, one end of the hose 3 is fixedly connected to a support frame 4, and an adjustment mechanism is provided at one end of the outer wall of the support frame 4, the adjustment mechanism includes a telescopic combination tube 5 fixedly connected to the front of the support frame 4, the outer wall of the telescopic combination tube 5 is rotatably connected to a plurality of rotating shafts 6, the outer wall of the rotating shaft 6 is wrapped with a water pumping pipe 7, one end of the water pumping pipe 7 is fixedly connected to the inner cavity of the telescopic combination tube 5, and the end of the water pumping pipe 7 away from the telescopic combination tube 5 is fixedly connected to a hollow counterweight 8.

[0035] During operation, the sampling body 1 is placed beside the waterway that needs to be tested, the telescopic combined tube 5 is placed flat above the waterway, and then the support frame 4 is adjusted to make the telescopic combined tube 5 at a suitable angle. The length of the pumping pipe 7 wrapped around the outer wall of the rotating shaft 6 is adjusted by turning a plurality of rotating shafts 6 provided on its outer wall. The pumping pipe 7 is sunk into the waterway to a suitable depth as required by using the hollow counterweight 8 provided at one end of the pumping pipe 7. At the same time, the water pump 2 is started to draw water into the sampling body 1 through the pumping pipe 7, thereby solving the problem that the traditional drinking water quality sampling and testing equipment cannot collect water quality at different depths offshore the river during use.

[0036] The two ends of the telescopic combined pipe 5 are a sub-tube and a main tube respectively, and the inner wall of the main tube is threadedly connected with the outer wall of the sub-tube.

[0037] During operation, a corresponding number of telescopic combined pipes 5 are selected according to the measured river channel width. Since the two ends of the telescopic combined pipe 5 are a sub-pipe and a main pipe respectively, the sub-pipe and the main pipe are installed with each other, thereby increasing the length of the telescopic combined pipe 5.

[0038] An electric valve 9 is provided at one end of the telescopic combined tube 5 close to the rotating shaft 6, and the shape of the inner cavity of the telescopic combined tube 5 is an hourglass shape.

[0039] The electric valve 9 can be used to automatically adjust the water flow. Its working principle is to use an electric actuator to open or close the valve. Common electric valve types include ball valves, gate valves and butterfly valves. The electric valve can be controlled in different ways, such as by switches, timers or sensors to achieve automatic control.

[0040] During operation, when water quality at different depths and in different areas is collected, the electric valve 9 is started to open the corresponding telescopic combination tube 5, so that the sampled water quality flows into the water pump 2. Since the inner cavity of the telescopic combination tube 5 is in the shape of an hourglass, when the water pump 2 extracts the target water quality, the water in the telescopic combination tube 5 in other areas will accumulate on the other side due to the influence of gravity, thereby avoiding the mixing of water quality in different areas and causing deviation in the detection data.

[0041] The output end of the water pump 2 is fixedly connected to a detection chamber 10. The inner wall of the detection chamber 10 is fixedly connected to a solubility detector 11. The bottom of the detection chamber 10 is fixedly connected to a drain pipe 12. The bottom of the drain pipe 12 is provided with a sample bottle 13.

[0042] The solubility detector 11 is an instrument used to measure the solubility of substances in solutions. It can help determine the dissolution ability of solutes in solvents under specific conditions. Solubility detectors include spectroscopic detectors, conductivity detectors, turbidity detectors, and light scattering detectors.

[0043] Spectroscopic detectors infer solubility by measuring the absorbance of solutions. For example, ultraviolet-visible spectrometers (UV-Vis) can be used to detect the concentration of solutes in solutions, and thus calculate solubility. Conductivity detectors estimate the concentration of solutes by measuring the conductivity of solutions. The degree of ionization of solutes is related to the conductivity of solutions, so solubility can be indirectly deduced. Turbidity detectors judge the dissolution of solutes by measuring the turbidity of solutions (such as transmittance). It is usually used to detect whether the dissolution state of solutes reaches saturation. Light scattering detectors use the principle of light scattering to detect particles in solutions, thereby evaluating the solubility of solutes.

[0044] During operation, the water quality of the river channel is pumped into the detection chamber 10 by the water pump 2. The solubility detector 11 arranged in the detection chamber 10 is used to detect the water quality solubility. Subsequently, the detected water is discharged into the sample bottle 13 through the drain pipe 12 for sampling and storage.

[0045] The bottom of the sample bottle 13 is clamped with a tray 14. The bottom of the tray 14 is fixedly connected to a motor 15. The bottom of the motor 15 is fixedly connected to a baffle 16.

[0046] During operation, by setting the motor 15 on the top of the baffle 16, the motor 15 is used to drive the tray 14 to rotate, so that several sample bottles 13 on the top of the tray 14 are moved to the lower part of the drain pipe 12 in turn, which is convenient for batch and rapid detection and sealing of water quality, greatly reducing the working time.

[0047] A chute 17 is opened at the center of the bottom inner wall of the sampling main body 1. The two ends of the baffle 16 are slidably connected to the inner wall of the chute 17.

[0048] During operation, by setting the chute 17 at the center of the bottom inner wall of the sampling main body 1, when the sample bottle 13 on the top of the tray 14 is filled with sample water quality, the baffle 16 is pulled, so that the baffle 16 together with the tray 14 and the sample bottle 13 are removed from the sampling main body 1, which is convenient for the staff to collect the sample bottle 13.

[0049] The four corners of the bottom of the sampling main body 1 are rotatably connected to fixed telescopic rods 18. The bottom of the fixed telescopic rods 18 is fixedly connected to a base 19.

[0050] During operation, the fixed telescopic rods 18 arranged at the four corners of the bottom of the sampling body 1 are adjusted to a suitable position, and the rivets are embedded in the base 19, so as to fix the sampling body 1 to prevent the sampling equipment from tipping over due to the pumping pipe 7 driven by the river water when encountering a turbulent river, thereby causing damage to the sampling equipment.

[0051] The outer wall of the fixed telescopic rod 18 is slidably connected to a limiting ring 20 , and one side of the outer wall of the limiting ring 20 is fixedly connected to a limiting frame 21 .

[0052] During operation, the sampling body 1 is placed in a suitable position, and the limiting ring 20 provided on the outer wall of the fixed telescopic rod 18 is moved to a suitable position. At this time, the limiting frame 21 is bent to support the fixed telescopic rod 18, thereby reinforcing the sampling body 1 and preventing the fixed telescopic rod 18 from loosening.

[0053] The working principle of the drinking water quality sampling and testing device provided by the utility model is as follows: by placing the sampling body 1 beside the waterway to be tested, adjusting the fixed telescopic rod 18 to a suitable position, embedding the rivet into the base 19, thereby fixing the sampling body 1, and moving the limit ring 20 provided on the outer wall of the fixed telescopic rod 18 to move it to a suitable position, at this time, bending the limit frame 21 to support the fixed telescopic rod 18, thereby reinforcing the sampling body 1 to prevent the fixed telescopic rod 18 from loosening, and to prevent the river water from driving the pumping pipe 7 to cause the sampling equipment to topple over when encountering a turbulent river, thereby causing damage to the sampling equipment. According to the measured width of the river channel, A corresponding number of telescopic combined tubes 5 are selected. Since the two ends of the telescopic combined tube 5 are a sub-tube and a main tube respectively, the sub-tube and the main tube are installed mutually, thereby increasing the length of the telescopic combined tube 5. The telescopic combined tube 5 is placed flat above the waterway, and then the support frame 4 is adjusted to make the telescopic combined tube 5 at a suitable angle. By turning a number of rotating shafts 6 arranged on its outer wall, the length of the water pumping pipe 7 wound around the outer wall of the rotating shaft 6 is adjusted. By using the hollow counterweight 8 arranged at one end of the water pumping pipe 7, the water pumping pipe 7 is sunk into the waterway at a suitable depth as required. At the same time, the water pump 2 is started to draw water into the sampling body 1 through the water pumping pipe 7, which solves the problem of traditional drinking water quality sampling and testing equipment being used in the waterway. During the process, the problem of being unable to collect water quality at different depths offshore the river is that when collecting water quality at different depths and in different areas, the electric valve 9 is started to open the corresponding telescopic combination tube 5, so that the sampled water quality flows into the water pump 2. Since the inner cavity of the telescopic combination tube 5 is in the shape of an hourglass, when the water pump 2 extracts the target water quality, the water in the telescopic combination tube 5 in other areas will accumulate on the other side due to the influence of gravity, so as to avoid the mixing of water quality in different areas and cause deviation in the detection data. The water quality of the river is pumped into the detection chamber 10 by the water pump 2, and the solubility detector 11 arranged in the detection chamber 10 is used to detect the solubility of the water quality. , then the tested water is discharged into the sample bottle 13 through the drainage pipe 12 for sampling and storage, and a motor 15 is arranged on the top of the baffle 16, and the motor 15 is used to drive the tray 14 to rotate, so that several sample bottles 13 on the top of the tray 14 are moved to the bottom of the drainage pipe 12, so as to facilitate batch and rapid detection and sealing of water quality, which greatly reduces the working time, and a slide groove 17 is arranged at the center of the bottom of the inner wall of the sampling body 1. When the sample bottle 13 on the top of the tray 14 is full of sample water, the baffle 16 is pulled, so that the baffle 16, the tray 14 and the sample bottle 13 are separated from the sampling body 1, which is convenient for the staff to collect the sample bottle 13.

[0054] It should be noted that although the above embodiments have been described in this text, it does not thereby limit the patent protection scope of the present utility model. Therefore, based on the innovative concept of the present utility model, any changes and modifications made to the embodiments described in this text, or equivalent structural or equivalent process transformations made using the content of the specification and drawings of the present utility model, and directly or indirectly applying the above technical solutions to other related technical fields, are all included within the patent protection scope of the present utility model.
