Abstract

[0001] This utility model relates to the field of ultrasonic application technology, specifically to an ultrasonic liquid level monitoring device. Background Technology
[0002] In the pultrusion process, resin impregnation is a crucial step. The original impregnation process used a tuning fork level alarm to monitor the resin level. However, over time, the resin at the position of the tuning fork inserted into the resin hardens, affecting the monitoring effect and rendering it ineffective, thus hindering normal production.
[0003] Using ultrasonic level monitoring allows for non-contact detection of resin levels, which is more efficient. However, existing ultrasonic level monitoring devices are usually fixed in one place to monitor the resin level. This prevents the ultrasonic level monitoring device from simultaneously monitoring storage tanks at different heights, which necessitates the installation of multiple ultrasonic level monitoring devices for simultaneous monitoring, increasing the cost of use.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example:
[0025] Please refer to Figures 1-4. An ultrasonic liquid level monitoring device in this embodiment includes a rectangular base plate 1. A frame 2 is fixedly connected to the top of the rectangular base plate 1. A sliding groove 3 is opened on the side of the frame 2. A sliding groove 4 is opened on the adjacent side of the sliding groove 3. A slider 5 is slidably connected to the inner wall of the sliding groove 3. A slider 6 is slidably connected to the inner wall of the sliding groove 4. A liquid storage tank 7 is fixedly connected to the top of the rectangular base plate 1. An ultrasonic detection device body 8 is arranged above the liquid storage tank 7.
[0026] The rectangular base plate 1 is equipped with a transmission mechanism via the ultrasonic testing device body 8, including an electric telescopic rod 10, an electric telescopic rod 21, and a moving plate 9.
[0027] The bottom of the movable plate 9 is fixedly connected to the guide rail 13, and the movable plate 9 is equipped with an adjustment component through the guide rail 13;
[0028] When monitoring the resin liquid in the storage tank 7, the ultrasonic detection device body 8 is first activated to monitor the resin liquid in the storage tank 7. The ultrasonic sensor probe emits an ultrasonic signal, which is then reflected by the liquid surface and received by the probe. The distance from the probe to the liquid surface is proportional to the time it takes for the ultrasonic wave to travel. When the liquid level rises or falls, the distance between the emitted and received ultrasonic waves will also change accordingly. These changing signals are then converted into analog voltages. The received voltage signals are sent to the microcontroller for processing and the measurement results are displayed. The microcontroller sets upper and lower limit reference nodes and compares and adjusts the output online to achieve the monitoring and alarm function. When monitoring storage tanks 7 at different heights at the same time, the electric telescopic rod 10 and the electric telescopic rod 2 11 are activated. Through the transmission mechanism, the moving plate 9 will drive the ultrasonic detection device body 8 to move along the x and y axes, thereby simultaneously monitoring storage tanks 7 at different heights or liquid levels.
[0029] At this time, the liquid level in the storage tank 7 is monitored, and multiple storage tanks 7 with different heights and liquid levels can be monitored at the same time without the need to set up multiple ultrasonic detection device bodies 8 to monitor at the same time, thus reducing production costs.
[0030] The bottom of the electric telescopic rod 10 is fixedly connected to the side of the slider 5, and the bottom of the electric telescopic rod 21 is fixedly connected to the side of the slider 26.
[0031] The movable plate 9 is located above the ultrasonic testing device body 8. One side of the movable plate 9 is fixedly connected to the output end of the electric telescopic rod 11, and the other side of the movable plate 9 is fixedly connected to the output end of the electric telescopic rod 10.
[0032] When simultaneously monitoring storage tanks 7 at different heights or liquid levels, the electric telescopic rod 10 is activated first, which moves the moving plate 9. Since the electric telescopic rod 11 is fixedly connected to the moving plate 9 and the slider 6, the moving plate 9 moves the slider 6 on the sliding groove 4. Then, the electric telescopic rod 11 is activated, moving the moving plate 9. Since the electric telescopic rod 10 is fixedly connected to the moving plate 9 and the slider 5, the moving plate 9 moves the slider 5 on the sliding groove 3. At this time, the x-axis and y-axis positions of the ultrasonic detection device body 8 are adjusted, allowing the ultrasonic detection device body 8 to simultaneously monitor different storage tanks 7.
[0033] At this point, the position of the ultrasonic detection device body 8 was adjusted so that the ultrasonic detection device body 8 could simultaneously monitor the liquid storage tanks 7 at different locations, thereby improving the utilization rate of the ultrasonic detection device body 8 and reducing production costs.
[0034] The adjustment assembly includes a slider 14 that is slidably connected to the inner wall of the guide rail 13, and a movable plate 12 that is fixedly connected to the top of the ultrasonic testing device body 8.
[0035] The side of the second movable plate 12 is fixedly connected to the side of the third slider 14. The bottom of the first movable plate 9 is rotatably connected to a threaded rod 15, which passes through the second movable plate 12 and is threadedly connected to the second movable plate 12.
[0036] A rotating shaft 16 is rotatably connected to the bottom of the movable plate 9. The rotating shaft 16 is located on the side of the threaded rod 15. A gear 17 is fixedly connected to the outer wall of the rotating shaft 16.
[0037] A second gear 18 is fixedly connected to the outer wall of the threaded rod 15. The second gear 18 meshes with the first gear 17. A motor 19 is provided below the moving plate 9. The bottom of the rotating shaft 16 is fixedly connected to the output end of the motor 19.
[0038] When facing liquid tanks 7 of different heights, if the height of the liquid tank 7 is greater than the original position of the ultrasonic detection device body 8, the motor 19 is started. The motor 19 will drive the rotating shaft 16 to rotate. The rotation of the rotating shaft 16 will cause the gear 17 to rotate. At this time, because the gear 17 and the gear 2 are meshed, the threaded rod 15 will also rotate when the rotating shaft 16 rotates. Since the threaded rod 15 is threadedly connected to the moving plate 2 12, under the limiting action of the guide rail 13 on the slider 3 14, the moving plate 2 12 will move up and down with the rotation of the threaded rod 15. At this time, the rotation direction of the motor 19 is controlled so that the moving plate 2 12 drives the ultrasonic detection device body 8 to move upward. At this time, the distance between the ultrasonic detection device body 8 and the liquid tank 7 can be recalculated to monitor the liquid level. Moreover, the ultrasonic detection device body 8 will not be unable to monitor because the height of the liquid tank 7 is greater than the original height of the ultrasonic detection device body 8. The position of the ultrasonic detection device body 8 in terms of height can be adjusted.
[0039] At this point, the height of the ultrasonic detection device body 8 was adjusted. When facing liquid storage tanks 7 of different heights, the height of the ultrasonic detection device body 8 can be flexibly adjusted, improving the flexibility of the device.
[0040] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
