Abstract
Description
Technical Field

[0002] The RF capacitor switch is a high-performance switching device that can achieve fast and reliable changes in capacitance, thereby achieving precise control of RF signals. The RF capacitor level switch is a new type of control device in RF capacitor switch technology that can achieve accurate control of the material level. The RF capacitor level switch is based on the RF admittance measurement principle. When the material level changes, the admittance value changes accordingly. The circuit unit converts the measured admittance value into a level signal output to achieve level measurement.
[0003] In actual use, it is necessary to insert the RF capacitance level switch into the silo that needs to be detected for measurement. The RF capacitance level switch is simply inserted into the silo and relies on the supporting force of the material in the silo to maintain a vertical state. During use, the RF capacitance level switch is easy to slip and has poor fixity, which will affect the accuracy of detection. In addition, the cross-sectional area of the silo is large, and there is friction between the materials. The level changes of solid materials in various places in the silo are not uniform, and there will be a large gap between the levels at two places. The single-point setting of the RF capacitance level switch is not comprehensive enough for level detection in the silo. Utility Model Content

[0022] Embodiment 1
[0023] like Figure 1 , Figure 2 and Figure 3 As shown, a radio frequency capacitance switch comprises a wiring table 8 and at least one probe rod 15 electrically connected to the wiring table 8, wherein the probe rod 15 is provided with a capacitance level sensor, and further comprises a long rod 1 and a clamping mechanism, wherein the clamping mechanism comprises a fixed plate 2 fixedly connected to one end of the long rod 1, an adjusting screw 3 is rotatably provided on one side of the fixed plate 2, a knob 4 is provided on the adjusting screw 3, a rubber sleeve is sleeved on the knob 4 for convenient rotation of the adjusting screw 3, a movable plate 7 is threadedly connected to the adjusting screw 3, a guide rod 5 which is relatively arranged and passes through the movable plate 7 is fixedly connected to one side of the fixed plate 2, the guide rod 5 is fixedly connected to a limiting block 6 at one end relative to the fixed plate 2, so as to prevent the movable plate 7 from moving too far, the lower ends of the fixed plate 2 and the movable plate 7 are fixedly connected with a clamping plate 10 which cooperates with the side wall of the silo, and a bridging groove 9 which cooperates with the side wall of the silo is provided on the side relative to the fixed plate 2 in the long rod 1, so as to facilitate bridging the long rod 1 on the side wall of the silo.
[0024] Through the above structure, the distance between the two side clamps 10 can be adjusted by rotating the screw, so that the side wall of the silo can be clamped by the clamping mechanism, which can improve the fixity during use. How to realize multi-point comprehensive detection of the material level in the silo, the specific structure is as follows:
[0025] like Figure 3 and Figure 4 As shown, the long rod 1 is provided with at least one relatively arranged groove 11, the groove 11 is rotatably provided with a rotating rod 12, the rotating rod 12 is slidably provided with a telescopic rod 13, the rotating rod 12 is rotatably arranged in the groove 11 through a damping rotating shaft, the telescopic rod 13 is slidably arranged in the rotating rod 12 through a damping slide rail, and the telescopic rod 13 is fixedly connected with a relatively arranged anti-collision block 14 cooperating with the rotating rod 12, which can avoid the collision between the probe rod 15 and the rotating rod 12 during the movement of the telescopic rod 13, and each of the probe rods 15 is fixedly arranged at the lower end of different telescopic rods 13, and the wiring table 8 is fixedly set at the upper end of the long rod 1.
[0026] Through the above structure, the positions of the probe rods 15 can be adjusted by rotating the rotating rod 12 and adjusting the position of the telescopic rod 13, so that the material level in the silo can be detected at multiple points.
[0027] Embodiment 2
[0028] like Figure 1 As shown, the wiring table 8 is provided with a wireless data transmission module and a wireless data transmission antenna electrically connected to the wireless data transmission module.
[0029] Through the above structure, the wireless data transmission module and the wireless data transmission antenna can cooperate to remotely transmit the level data detected by each probe rod 15 to the supervisory staff.
[0030] When the utility model is implemented, the long rod is first installed on the silo during use. Specifically, the groove on the long rod is placed on one side of the silo, and the fixed plate is attached to the inner wall of the silo on the other side. Then, the knob and the adjusting screw are turned, and the movable plate can be driven to move toward the outer wall of the silo under the action of the guide rod until the clamping plates on both sides are tightly attached to the side walls of the silo, and the installation is completed. In this way, the probe rod inserted into the material is well fixed during the detection process, and the probe rod can be prevented from tilting or sliding.
[0031] Before installing the probe rod, according to the material position that needs to be detected, rotate the rotating rod to turn the rotating rod out of the groove, and slide the telescopic rod to adjust the distance between the probe rod and the rotating rod, so as to achieve the purpose of adjusting the position of each probe rod. In this way, during use, multiple probe rods can be used to detect the level of materials around the long rod, and level detection can be performed at multiple points at the same time, so as to perform more comprehensive level detection on materials with uneven height distribution in the silo. The probe rod transmits the detected data to the wiring table, and then transmits the data remotely to the staff who supervises the silo through the wireless data transmission module and the wireless data transmission antenna.
