Description

Technical Field

[0001] This utility model relates to the field of river water sampling technology, and in particular to a quantitative injection device for river water sampling. Background Technology

[0002] Water resources are an essential resource for human survival; however, river pollution is a frequent occurrence due to wastewater discharge and chemical spills. To protect the safety and purity of water resources, regular monitoring of river water is crucial. Currently, river water sampling and testing primarily relies on traditional manual sampling methods. This method has several problems. First, it suffers from inaccurate sampling; manual operation makes it difficult to control the sampling time and quantity, often resulting in inaccurate results. Second, it is inconvenient, requiring frequent entry and exit from the river for sampling, which is not only time-consuming and labor-intensive but may also disturb the surrounding environment.

[0003] During the use of the filling device, river water needs to be sampled due to pollution. Therefore, the river water needs to be automatically drawn. The drawn river water also needs to be stored in a container in a certain quantity. Otherwise, if there is too much or too little water in the container, the detected data will be inaccurate. Utility Model Content

[0004] This disclosure relates to a river water sampling and quantitative dispensing device. A telescopic tube automatically inserts into the river to extract water, which is then injected into a quantitative cup. The volume of water in the cup can be accurately determined based on the markings. The water in the quantitative cup is then injected into a corresponding container, allowing for quantitative sampling and storage of the river water in the container. This facilitates subsequent testing of the river water in the container, ensuring that the quantitative river water data collected each time is accurate and error-free, thus guaranteeing the accuracy and reliability of the river water testing data.

[0025] Example 1: Please refer to Figures 1 to 4 :

[0026] This utility model proposes a river water sampling and quantitative injection device, comprising: a floating body 1; four threaded grooves are formed at the bottom of the inner cavity of the floating body 1; the floating body 1 is moved to the middle of the river surface for sampling using a wooden paddle; a support block 101 is fixedly installed at the upper edge of the floating body 1, and the top of the support block 101 is fixedly supported at the bottom of the bearing plate 4 to provide stable support for the bearing plate 4; a foam board 102 is fixedly installed at the lower end of the outer annular sidewall of the floating body 1 to assist the floating body 1 in floating on the river surface; and the bottom of the inner cavity of the floating body 1... A base plate 2 is fixedly installed at the left end of the floating body 1, and five slots are provided at the right end of the base plate 2; three grooves are provided at the top of the base plate 2; a fixed upright plate 3 is fixedly installed at the bottom of the floating body 1, and a fixed slot is provided at the upper end of the fixed upright plate 3; a small water pump 301 is fixedly installed at the fixed slot of the fixed upright plate 3; a through water pump 302 is connected to the right end of the small water pump 301, and a telescopic pipe 303 is connected to the right end of the water pump 302; the telescopic pipe 303 passes through the middle of the threaded cylinder 405, and the lower end of the telescopic pipe 303 passes through the threaded cylinder. At the lower end of 405, a through discharge pipe 304 is connected to the left end of the small water pump 301. The lower end of the discharge pipe 304 corresponds vertically to the metering cup 203. At the same time, the telescopic tube 303 in the threaded cylinder 405 is also inserted into the river water. The small water pump 301 is started, and the river water is pumped up using the telescopic tube 303 at the right end of the pumping pipe 302. Then, the water flows from the lower end of the discharge pipe 304 into the metering cup 203 below, filling the metering cup 203 with river water. According to the requirement of quantitative river water sampling, the river water in the metering cup 203 is scooped out with a spoon and discharged from the metering cup 203. The scale on the side wall accurately indicates the water volume. Symmetrical auxiliary plates 305 are fixedly installed on the side wall at the lower end of the fixed upright plate 3. Through screws are rotatably installed at both ends of the auxiliary plates 305. The screws on the auxiliary plates 305 are rotated and inserted into the threaded grooves of the floating body 1 to fix and restrict the auxiliary plates 305 and the fixed upright plate 3. This way, the fixed upright plate 3 will not tilt when touched. A bearing plate 4 is fixedly installed on the right side wall of the fixed upright plate 3. A through round hole is opened at the right end of the bearing plate 4, and a rotating groove is opened on the inner side wall of the round hole of the bearing plate 4.

[0027] The base plate 2 has three recessed slots where containers 201 are placed. A top cover is installed at the opening of each container 201, and a through-hole is formed in the center of the top cover. A delivery pipe 204 is inserted into the container 201 through the hole in the top cover. Vertically upward support rods 202 are fixedly installed in five slots on the base plate 2. Metering cups 203 are fixedly installed at the upper ends of the five support rods 202. Graduation marks are evenly distributed on the outer sidewall of the metering cups 203. The containers 201 and metering cups 203... All three are transparent. Three through-feed tubes 204 are inserted into the bottom of the metering cup 203. Valves are installed at the upper ends of the three tubes 204 respectively. The lower ends of the tubes 204 are inserted into the corresponding containers 201. When the valves on the tubes 204 are opened, the river water in the metering cup 203 will flow into the corresponding containers 201 through the tubes 204. The river water in the metering cup 203 is injected into the containers 201 in a metered manner. The river water in the metering cup 203 is added to the containers 201 each time it enters them.

[0028] A cantilever frame 401 is fixedly installed at the bottom right end of the bearing plate 4, and a motor 402 is fixedly installed in the middle of the cantilever frame 401. The shaft of the motor 402 passes through the shaft hole 404, and a toothed disc 403 is fixedly installed on the shaft of the motor 402. The teeth on the toothed disc 403 mesh with the grooves on the toothed disc 406. When the motor 402 is started, the toothed disc 403 on the shaft will rotate, driving the toothed disc 406 to rotate. The toothed disc 406 rotates on the threaded cylinder 405, which will move the threaded cylinder 405 downward. At this time, the threaded cylinder 405... The lower end will be inserted into the river water. A through shaft hole 404 is opened on the bearing plate 4. A through threaded cylinder 405 is inserted into the round hole at the right end of the bearing plate 4. A toothed disc 406 is rotatably installed on the annular side wall of the threaded cylinder 405. A through threaded hole is opened in the middle of the toothed disc 406. A rotating ring is fixedly installed at the lower end of the toothed disc 406. The rotating ring at the lower end of the toothed disc 406 is rotatably installed in the rotating groove of the bearing plate 4. When the toothed disc 406 rotates, the rotating ring is restricted by the rotating groove and will not move up and down. The rotation of the toothed disc 406 will drive the threaded cylinder 405 to move up and down.

[0029] Example 2, based on Example 1, such as Figure 1 and Figure 4 As shown, symmetrical auxiliary plates 305 are fixedly installed on the side wall at the lower end of the fixed upright plate 3, and through screws are respectively installed at both ends of the auxiliary plates 305. After removing the auxiliary plates 305 and screws, the fixed upright plate 3 is fixedly glued to the floating body 1 to stabilize and restrict the fixed upright plate 3. This prevents the fixed upright plate 3 from tilting when touched, prevents the screws from loosening after long-term use and making it impossible to continue fixing the fixed upright plate 3, and also saves on parts costs.

[0030] The working principle of this embodiment is as follows: During use, the floating body 1 is moved to the middle of the river surface for sampling using a wooden paddle. The serrations on the serrated disc 403 mesh with the grooves on the grooved disc 406. When the motor 402 is started, the serrated disc 403 on the shaft will rotate. The serrated disc 403 drives the grooved disc 406 to rotate. The grooved disc 406 rotates on the threaded cylinder 405, which moves the threaded cylinder 405 downward. At this time, the lower end of the threaded cylinder 405 will be inserted into the river water. At the same time, the telescopic tube 303 in the threaded cylinder 405 will also be inserted into the river water. The small water pump 3 is then started. 01. Use the telescopic pipe 303 at the right end of the pumping pipe 302 to pump the river water up, and then let it flow from the lower end of the discharge pipe 304 into the metering cup 203 below. Fill the metering cup 203 with river water. According to the requirement of quantitative sampling of river water, use a spoon to scoop out the river water from the metering cup 203. The water volume can be accurately determined from the scale on the side wall of the metering cup 203. Then open the valve on the delivery pipe 204. The river water in the metering cup 203 will flow into the corresponding container 201 through the delivery pipe 204. The river water in the metering cup 203 is quantitatively injected into the container 201.
