Description

Technical Field

[0001] This invention relates to the field of solution concentration detection technology, specifically a rapid solution concentration detection device for high school chemistry experiments. Background Art

[0002] Solution concentration detection is a quantitative analytical process that determines the concentration of a solution by measuring the relative amounts of solute and solvent in the solution using specific methods and techniques. It is a core, fundamental operation in fields such as chemical experiments, industrial production, environmental monitoring, and pharmaceutical research and development, with the aim of obtaining precise concentration data of the solute in the solution.

[0003] In high school chemistry experiments, although traditional methods such as titration and colorimetry are the main means of detecting solution concentration, with the development of experimental equipment, we will also come into contact with some instruments specifically designed for solution concentration detection, so as to quickly determine the concentration.

[0004] In existing technologies, liquid concentration sensors can be used to quickly detect the concentration of solutions in chemical experiments. The conventional detection method involves personnel manually inserting the probe of the concentration sensor into the glass bottle containing the solution for detection. Usually, only one glass bottle of solution can be detected at a time. However, in chemical experiment teaching, it is necessary to detect multiple glass bottles containing solutions. This detection method is inefficient and increases the workload of personnel. Therefore, we propose a rapid solution concentration detection device for high school chemistry experiments to solve the shortcomings of the existing technology. Summary of the Invention

[0009] The present invention is further configured such that the positioning component includes a fixed plate, a screw, a drive motor, and a movable plate. The bottom end of the fixed plate is fixedly connected to the top end of the detection platform. One end of the screw is rotatably connected to the outside of the fixed plate. The bottom end of the drive motor is fixedly connected to the top end of the top of the detection platform. The output shaft of the drive motor is fixedly connected to one end of the screw. The inner wall of the movable plate is threadedly connected to the surface of the screw.

[0011] The present invention is further configured such that the positioning component includes a movable rod, a clamping rod, an anti-slip pad, and a rotating shaft. One end of the movable rod is rotatably connected to one end of the connecting rod, one end of the clamping rod is rotatably connected to the other end of the movable rod, the outer side of the anti-slip pad is fixedly connected to the outer side of the clamping rod, the bottom end of the rotating shaft is fixedly connected to the top of the detection platform, and the two clamping rods are rotatably connected through the rotating shaft.

[0012] The present invention is further configured such that the lifting assembly includes a movable groove and a guide bar, the movable groove being formed inside the bracket, and the guide bar being fixedly connected to the inner walls on both sides of the movable groove.

[0015] Beneficial effects:

[0016] I. This invention, through its positioning components, can simultaneously fix multiple glass bottles. The glass bottles containing the solution to be tested are placed on the placement platform. By activating the drive motor, the screw, moving plate, connecting rod, movable rod, and clamping rod work together to rotate the two clamping rods around the pivot, causing the two anti-slip pads to move closer together, thus clamping and fixing the glass bottles.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1-5 As shown, the present invention provides a technical solution: a rapid detection device for solution concentration in high school chemistry experiments, including a detection platform 1, a positioning component 2 at the top of the detection platform 1, four placement platforms 3 fixedly connected to the top of the detection platform 1, a glass bottle 4 at the top of the placement platform 3, a bracket 5 fixedly connected to the outer side of the detection platform 1, a lifting component 6 at the inner side of the bracket 5, a connecting arm 7 fixedly connected to the output end of the lifting component 6, a mounting plate 8 fixedly connected to one end of the connecting arm 7, four concentration sensors 9 fixedly mounted at the top of the mounting plate 8, and a detection probe 10 fixedly connected to the bottom end of the concentration sensor 9.

[0027] The glass bottle 4 containing the solution to be tested is placed on the placement platform 3. Four glass bottles 4 can be placed at a time. The positioning component 2 can fix multiple glass bottles 4 at the same time, which can improve stability and facilitate subsequent testing. On the other hand, the glass bottle 4 can be centered to ensure that the detection probe 10 can be inserted into the glass bottle 4 for testing. The lifting component 6 can drive the concentration sensor 9 and the detection probe 10 to move downward to detect the concentration of the solution in the glass bottle 4.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the positioning assembly 2 includes a fixed plate 201, a screw 202, a drive motor 203, a moving plate 204, a guide rail 205, a slider 206, a connecting rod 207, a movable rod 208, a clamping rod 209, an anti-slip pad 210, and a rotating shaft 211. The bottom end of the fixed plate 201 is fixedly connected to the top end of the testing table 1. One end of the screw 202 is rotatably connected to the outside of the fixed plate 201. The bottom end of the drive motor 203 is fixedly connected to the top end of the testing table 1. The output shaft of the drive motor 203 is fixedly connected to one end of the screw 202. The inner wall of the moving plate 204 is threadedly connected to the surface of the screw 202. The outer side of the guide rail 205 is fixedly connected to the top of the testing table 1. The inner wall of the slider 206 is slidably connected to the outer side of the guide rail 205. The outer side of the slider 206 is fixedly connected to the outer side of the moving plate 204. One end of the connecting rod 207 is fixedly connected to the outer side of the moving plate 204. One end of the movable rod 208 is rotatably connected to one end of the connecting rod 207. One end of the clamping rod 209 is rotatably connected to the other end of the movable rod 208. The outer side of the anti-slip pad 210 is fixedly connected to the outer side of the clamping rod 209. The bottom end of the rotating shaft 211 is fixedly connected to the top of the testing table 1. The two clamping rods 209 are rotatably connected through the rotating shaft 211.

[0029] By starting the drive motor 203, the screw 202 rotates, which in turn moves the moving plate 204 horizontally. When the moving plate 204 moves, it moves the connecting rod 207 horizontally, causing one end of the connecting rod 207 to push two movable rods 208. The movable rods 208 then push the clamping rods 209, causing the two clamping rods 209 to rotate around the rotating shaft 211. This causes the two anti-slip pads 210 to move closer to each other, clamping and fixing the glass bottle 4. Multiple glass bottles 4 can be fixed at the same time.

[0030] like Figure 1 , Figure 4 and Figure 5 As shown, the lifting assembly 6 includes a movable groove 601, a guide bar 602, a lifting motor 603, a second screw 604, a lifting plate 605, and a sliding plate 606. The movable groove 601 is opened inside the bracket 5. The guide bar 602 is fixedly connected to the inner walls of both sides of the movable groove 601. The bottom end of the lifting motor 603 is fixedly connected to the top end of the bracket 5. The upper and lower ends of the second screw 604 are rotatably connected to the inner wall of the movable groove 601. The top end of the second screw 604 is fixedly connected to the output shaft of the lifting motor 603. The inner wall of the lifting plate 605 is threadedly connected to the outer side of the second screw 604. The outer side of the lifting plate 605 is fixedly connected to one end of the connecting arm 7. The sliding plate 606 is fixedly connected to both sides of the lifting plate 605. The inner wall of the sliding plate 606 is slidably connected to the outer side of the guide bar 602.

[0031] By starting the lifting motor 603, the screw 604 rotates, which in turn drives the lifting plate 605 to move up and down. At the same time, it drives the concentration sensor 9 and the detection probe 10 to move downward, so that the detection probe 10 can be inserted into the glass bottle 4 to detect the solution concentration. This allows multiple glass bottles 4 to be tested at the same time, improving work efficiency and ensuring that the insertion depth of the detection probe 10 is consistent.

[0032] Working principle: When in use, place the glass bottle 4 containing the solution to be tested on the placement platform 3. Four glass bottles 4 can be placed at a time. After placement, start the drive motor 203 to drive the screw 202 to rotate, which will drive the moving plate 204 to move horizontally. When the moving plate 204 moves, it can drive the connecting rod 207 to move horizontally, so that one end of the connecting rod 207 pushes two movable rods 208. The movable rods 208 push the clamping rods 209, so that the two clamping rods 209 rotate around the rotating shaft 211, causing the two anti-slip pads 210 to move closer to each other, clamping and fixing the glass bottle 4. Multiple glass bottles 4 can be fixed at the same time, which can improve stability and facilitate subsequent testing. On the other hand, the glass bottle 4 can be centered to ensure that the detection probe 10 can be inserted into the glass bottle 4 for testing.

[0033] Once the glass bottle 4 is fixed, the lifting motor 603 is started, which drives the screw 604 to rotate, causing the lifting plate 605 to move up and down. At the same time, the sliding plate 606 slides on the guide bar 602. When the lifting plate 605 moves downward, it can drive the connecting arm 7 and the mounting plate 8 to move downward, which in turn drives the concentration sensor 9 and the detection probe 10 to move downward, so that the detection probe 10 can be inserted into the glass bottle 4 to detect the solution concentration. The detection result is displayed on the display screen of the concentration sensor 9, which is convenient for personnel to understand intuitively. Multiple glass bottles 4 can be detected at the same time, improving work efficiency.

[0034] It is worth noting that the specific model of the concentration sensor 9 is the MSDR-PRT liquid concentration sensor. It directly contacts the liquid through the detection probe 10 to sense the concentration change, and then converts the chemical signal into an electrical signal. The electrical signal is then analyzed, calibrated, and outputs the concentration value.

[0035] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
