[0022] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The utility model embodiment is a plant growth regulator production liquid level detection device, which includes a container 1, a C-shaped fixed plate 2 is fixedly connected to one side of the container 1, a scale 8 is provided on one side of the fixed plate 2, a floating plate 4 is provided inside the container 1, a counterweight plate 5 is fixedly connected to the top of the floating plate 4, a connecting rope 6 is connected to the top of the counterweight plate 5, an indicator needle 12 is movably connected to one side of the fixed plate 2 close to the scale 8, the other end of the connecting rope 6 extends to the top of the container 1 and then passes through the top of the fixed plate 2 and is fixedly connected to the indicator needle 12, the buoyancy of the floating plate 4 is greater than that of the counterweight plate 5, and the gravity of the indicator needle 12 is less than that of the counterweight plate 5. The interior of the container 1 can be used to store plant growth regulators. When producing plant growth regulator, the rise and fall of the liquid level of the regulator in the container 1 will drive the counterweight plate 5 to move up and down in the container 1 through the buoyancy of the floating plate 4. The counterweight plate 5 that moves up and down can realize the opposite movement of the indicator needle 12 through the connecting action of the connecting rope 6, so that the current liquid level can be quickly and accurately understood through the position of the indicator needle 12 at the scale 8, thereby realizing real-time and intuitive detection of the liquid level of the regulator in the container 1, which is intuitive and easy to use, and has a simple overall structure and occupies a small space. It can be easily integrated into the existing plant growth regulator production equipment, reducing the production cost and installation difficulty, and ensuring the reliability and stability of the liquid level detection.

[0024] Reference Figure 3 and Figure 4 A micro switch 15 is installed on the side of the fixed plate 2 away from the container 1 and at both ends close to the scale 8. A touch plate 13 that can contact the micro switch 15 is fixedly connected to the side of the indicator needle 12 close to the micro switch 15. The micro switches 15 are arranged at the upper and lower ends of the fixed plate 2. When the indicator needle 12 moves upward to the top, the upper micro switch 15 can be triggered by the touch plate 13. When the indicator needle 12 moves downward to the bottom, the lower micro switch 15 can be triggered by the touch plate 13. Therefore, under the action of the two micro switches 15, the highest liquid level in the container 1 can be detected. The highest point and the lowest point of the liquid level are monitored. Monitoring the highest point of the liquid level can ensure that the liquid will not overflow the container 1, thereby avoiding possible safety issues such as environmental pollution, equipment damage and personal injury. Monitoring the lowest point of the liquid level can ensure that the liquid supply in the production process will not be interrupted, thereby avoiding equipment shutdown or production accidents caused by too low a liquid level. A warning light 11 is fixedly connected to the top of the fixed plate 2. The micro switch 15 can be electrically connected to the warning light 11 to control the operation of the warning light 11 through the trigger signal of the micro switch 15. The warning light 11 can be used to remind personnel.

[0025] Reference Figure 3 and Figure 4A U-shaped mounting plate 9 is fixedly connected to the top of the fixing plate 2, and two rollers 10 are installed on the inner side of the mounting plate 9. The connecting rope 6 is slidably connected to the middle of the roller 10. When the connecting rope 6 moves, it slides on the roller 10, which can make the connecting rope 6 move more smoothly, so that the indicator needle 12 can move more flexibly.

[0026] Reference Figure 2 , Figure 3 and Figure 4 A first guide rod 3 is fixedly connected to the bottom of the inner wall of the container 1, and the floating plate 4 and the counterweight plate 5 are both slidably connected to the first guide rod 3. When the floating plate 4 and the counterweight plate 5 move up and down, they are slidably connected to the first guide rod 3, which can make the movement of the counterweight plate 5 more stable, and is also beneficial to the stability of the contact between the connecting rope 6 and the roller 10. A second guide rod 7 is fixedly connected to the inner side of the fixed plate 2, and the indicator needle 12 is slidably connected to the second guide rod 7. When the indicator needle 12 moves up and down, it slides on the outside of the second guide rod 7, which is beneficial to ensure the stability of the up and down movement of the indicator needle 12, so as to ensure the coordinated use of the indicator needle 12 and the scale 8.

[0027] Reference Figure 3 and Figure 4 , the two micro switches 15 are connected to the fixed plate 2 through an adjusting component, the adjusting component includes an L-shaped connecting plate 14, a screw 16 threadedly connected to the inside of the connecting plate 14 and a knob 17 fixedly connected to one end of the screw 16, the end of the screw 16 opposite to the knob 17 is in contact with the outer side of the fixed plate 2, the micro switch 15 is fixedly connected to the connecting plate 14, and the screw 16 is rotated by rotating the knob 17 to rotate and fit the outer side of the fixed plate 2, so that the micro switch 15 can be positioned on the fixed plate 2 through the connecting plate 14, and the screw 16 can be separated by rotating the knob 17, so as to facilitate the adjustment of the position of the connecting plate 14, so as to facilitate the adjustment of the position of the micro switch 15 according to the requirements of the liquid level monitoring height, and it is flexible to use.

[0028] The top of the scale 8 is set as the zero scale, and the zero scale starts from the top of the scale 8. The position of the indicator needle 12 is the height of the liquid level inside the container 1, which is convenient for reading the liquid level data.

[0029] Working principle: The interior of container 1 can be used to store plant growth regulators. The rise and fall of the regulator liquid level in container 1 will drive the counterweight plate 5 to move up and down in container 1 through the buoyancy of the float plate 4. The counterweight plate 5 that moves up and down can realize the opposite movement of the indicator needle 12 through the connection of the connecting rope 6, so that the current liquid level can be quickly and accurately understood through the position of the indicator needle 12 at the scale 8, thereby realizing real-time and intuitive detection of the regulator liquid level in container 1. It is intuitive and easy to use, and the overall structure is simple, occupies a small space, and can be easily integrated into existing plant growth regulator production equipment, reducing production costs and installation difficulty, and ensuring the reliability and stability of liquid level detection.
