Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of charging devices, in particular to a wireless charging mechanism for an inclinometer. Background Art
[0002] An inclinometer is an in-situ monitoring instrument mainly used to measure the apex angle and azimuth angle of engineering structures such as drill holes, foundation pits, foundation bases, walls, and dam slopes. By measuring the component of the earth's gravity in the measurement direction, the inclinometer can simultaneously measure the inclination changes in both the X / Y directions and calculate the inclination direction and angle at that point. This instrument is widely used in the fields of water conservancy and hydropower, mining and metallurgy, transportation, and urban construction geotechnical engineering, and plays an important role in ensuring the design, construction, and use safety of geotechnical engineering. The types of inclinometers include intelligent inclinometers such as resistance strain type, accelerometer type, and electronic meter type, and these different types of inclinometers play a key role in ensuring project quality and safety.
[0003] An inclinometer generally consists of a sensor and a controller (collector). The controller and the sensor are connected by a wire. During operation, the signal collected by the sensor is output to the controller for analysis and processing, and then the slope data of the relevant area is obtained. Since the structure and shape of the controller are relatively large, the length of the wire connecting the controller and the sensor is relatively long. Affected by factors such as the harsh on-site measurement environment, it is inconvenient for the measurement personnel to retract and release the wire, and there is a probability that the wire will be entangled, pulled, or even broken by other objects. Therefore, in existing inclinometers with more advanced functions, the sensor and the controller communicate wirelessly through a wireless communication module (the data detected by the sensor is sent through a built-in WiFi data sending module, and the controller receives and processes the data through a WiFi data receiving module). Although the inclinometer with a wireless communication method has achieved the advantages of convenient use and improved work efficiency to a certain extent, due to structural limitations, there are still some technical problems. Specifically, the external shape structure of the sensor is small for detection needs, so the capacity of the built-in battery is relatively small and the sensor consumes a lot of power. Therefore, the battery needs to be charged after working for a period of time. The current charging method for the sensor battery is to insert an external charger plug into the charging socket of the sensor. In this way, due to the existence of the jack of the charging plug, it is relatively difficult to achieve the full-sealed effect of the sensor, because the sensor is prone to contact with water (including rain on-site) during operation, increasing the probability of water entering the sensor and damaging its internal electronic components. With the development of charging technology, wireless charging technology has also made progress. Therefore, it is very necessary to provide a wireless charging mechanism based on a wireless charging transmitting and receiving module that can realize wireless charging of the sensor and reduce the probability of water entering the sensor. Summary of the Utility Model
[0004] In order to overcome the drawback that sensors used in existing inclinometers are charged in a wired manner, and there is a risk that external water and the like enter the sensor interior through the charging socket jacks, resulting in an increased probability of damage to internal electronic components and the like, the present utility model provides a wireless charging mechanism for an inclinometer based on a wireless charging transmitter and a wireless charging receiver module body. The wireless charging receiver module is installed at the front end inside the sensor detection tube. During application, it can conveniently charge the battery inside the sensor, and during charging, it can achieve automatic on / off control of the wireless charging transmitter module end. On the basis of achieving automatic control, it also achieves the purpose of energy conservation.
[0005] The technical solution adopted by the present utility model to solve its technical problems is as follows:
[0006] A wireless charging mechanism for an inclinometer includes a wireless charging transmitter module, a wireless charging receiver module body, a charging bin, and a detection switch; it is characterized in that it further has a prompting circuit and a fixing mechanism; there is a fixing groove horizontally inside the charging bin, the detection switch is installed on one side inside the fixing groove, the wireless charging transmitter module and the prompting circuit are installed inside the charging bin; there is an installation groove at the upper end of the fixing groove, the fixing mechanism includes a guiding tube, a spring, and a positioning bead. The lower end of the guiding tube is an open structure, the spring and the steel ball are located inside the guiding tube from top to bottom, there is a limiting ring outside the lower end of the guiding tube, and the guiding tube is installed in the installation groove; the wireless charging receiver module is installed inside one side end of the probe tube of the inclinometer sensor, and the power output end of the wireless charging receiver module is electrically connected to the power input end of the battery of the sensor; there is a fixing ring outside the probe tube; the wiring terminal of the detection switch is electrically connected between one of the power input ends of the wireless charging transmitter module.
[0007] Furthermore, the prompting circuit includes a resistor and a light-emitting diode that are electrically connected, and one end of the resistor is connected to the positive pole of the light-emitting diode.
[0008] Furthermore, the lower end of the positioning bead is located outside the lower side of the limiting ring, and the lower end of the limiting ring and the lower end of the installation groove are in the same plane.
[0009] Furthermore, the detection switch is a normally open micro-motion push-button power switch.
[0010] Furthermore, the outer diameter of the probe tube of the sensor is smaller than the inner diameter of the fixing groove.
[0011] Furthermore, the width of the fixing ring is greater than the outer diameter of the lower end of the positioning bead.
[0012] Furthermore, the upper and lower ends of one side of the probe tube of the sensor respectively have limiting rods, and the upper and lower ends inside the fixing groove respectively have guiding openings horizontally. After the probe tube of the sensor enters the fixing groove, the limiting rods at the upper and lower ends of the probe tube of the sensor are respectively located inside the two guiding openings.
[0013] The beneficial effects of the present utility model compared with the prior art are as follows: (1) Based on the wireless charging transmitting and wireless charging receiving module bodies, the wireless charging receiving module is installed at the front end inside the sensor detection head. During application, it can conveniently charge the battery inside the sensor. Since the sensor itself does not have a power socket and is completely sealed, the probability of external water entering the sensor is reduced; (2) During charging, after the probe tube of the sensor is inserted into the fixing groove, the internal contacts of the detection switch are closed, and then the wireless charging transmitting module will be powered on and work. Moreover, the steel ball will enter the fixing circle to effectively fix the charging part (correspondingly, due to the fixed positions of the wireless charging receiving module and the wireless charging transmitting module, the charging efficiency can be improved). Since the automatic on / off control of the wireless charging transmitting module can be controlled during charging, on the basis of realizing automatic control, the purpose of energy saving is also achieved. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] The present utility model will be further described below with reference to the drawings and embodiments.
[0015] Figure 1 It is a schematic diagram of the overall structure of the present utility model.
[0016] Figure 2 It is a circuit diagram of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] Figure 1 、 2 As shown in the figure, an inclinometer wireless charging mechanism includes a wireless charging transmitting module A1, a wireless charging receiving module body A2, a charging bin 1, and a detection switch S1; it also has a prompting circuit 2 and a fixing mechanism 3. There is a fixing groove 101 (the left end is an open structure) horizontally inside the charging bin 1. The detection switch is installed in the middle of the right end inside the fixing groove 101, and its button is located on the left side. The wireless charging transmitting module A1 and the prompting circuit 2 are installed on the upper part of the lower end inside the charging bin 1. There is an upward convex installation groove 102 at the upper middle part of the fixing groove 101. The fixing mechanism 3 includes a guiding tube 31, a spring 32, and a positioning steel ball 33. The lower end of the guiding tube 31 is an open structure, and the spring 32 and the steel ball 33 are located inside the guiding tube 31 from top to bottom. There is a limiting ring 34 with an inner diameter smaller than the outer diameter of the steel ball outside the lower end of the guiding tube 31. The guiding tube 31 is installed in the installation groove 102. The wireless charging receiving module A2 is hermetically installed at the lower end inside the right side of the probe tube 4 of the inclinometer sensor. The power output end of the wireless receiving module body A2 and the power input end of the sensor A3 (including the two poles of the battery G1) are connected by wires. There is a ring-shaped concave fixing circle 5 on the outer right side of the probe tube 4. The power input end of the wireless charging transmitting module A1 and the two poles of the AC 220V power supply are respectively connected by wires. The two wiring terminals S1 of the detection switch are connected by wires between one pole of the AC power supply and one of the power input ends of the wireless charging transmitting module A1.
[0018] Figure 1 , 2 As shown, the prompting circuit includes a resistor R1 and a light-emitting diode VL connected by circuit board wiring. One end of the resistor R1 is connected to the positive pole of the light-emitting diode VL, and the light-emitting surface of the light-emitting diode VJ is located outside the upper end of the charging bin 1. The lower end of the steel ball 33 is located outside the lower side of the limiting ring 34, and the lower end of the limiting ring 34 and the lower end of the installation groove 102 are in the same plane. The detection switch S1 is a normally open push-button micro power switch. The outer diameter of the probe tube 4 of the sensor is slightly smaller than the inner diameter of the fixed groove 101. The width of the fixing ring 5 (the upper outer sides of the left and right ends are inclined structures to facilitate the steel ball to enter or escape from the fixing ring) is slightly larger than the outer diameter of the lower end of the steel ball 33. When the right end of the probe tube 4 of the sensor is at the right stop point of the fixed groove 101, the lower end of the steel ball 33 and the fixing ring 5 are in a vertical plane from top to bottom, the lower end of the steel ball 33 is located inside the upper end of the fixing ring 5, the right side of the probe tube 4 of the sensor contacts the button of the detection switch S1, and the internal contacts of the detection switch S1 are closed. The upper and lower ends of the right side of the probe tube 4 of the sensor are respectively provided with a limiting rod 6 higher than the probe tube, and the middle parts of the upper and lower ends in the fixed groove 101 are respectively provided with a guiding port 7 horizontally. After the probe tube 4 of the sensor enters the fixed groove 101, the limiting rods 6 at the upper and lower ends of the right side of the probe tube 4 of the sensor are respectively located in the two guiding ports 7.
[0019] Figure 1 , 2As shown in the figure, this new device is based on the wireless charging transmitting module A1 and the wireless charging receiving module A2 body. The wireless charging receiving module A2 is installed at the lower front end inside the sensor probe tube 4. During application, it can conveniently charge the battery G1 inside the sensor. Since the sensor itself does not have a power socket and is completely sealed, the probability of external water entering the sensor is reduced. Specifically, during charging, after the user inserts the probe tube 4 of the sensor into the fixing slot 101 by hand, the limiting rods 6 at the upper and lower ends on the right side of the probe tube 4 of the sensor are respectively located inside the two guiding ports 7. Due to the limiting effect of the limiting rod 6 and the guiding port 7 (the limiting rod 6 can only move horizontally left and right along the guiding port 7 and will not rotate), it prevents the wireless charging receiving module A2 from not being located at the lower end and the distance between the wireless charging transmitting module A1 and the wireless charging receiving module A2 from being too large, resulting in a reduction in charging efficiency. During the process of inserting the probe tube 4 of the sensor into the fixing slot, the probe tube 5 will push the steel ball 33 upward, and the steel ball 33 enters inside the upper end of the fixing ring 5. Since the steel ball 33 entering the fixing ring can effectively fix the charging part and prevent the probe tube 4 from being disengaged from the fixing slot 101, correspondingly, due to the fixed positions of the wireless charging receiving module and the wireless charging transmitting module, the charging efficiency is further ensured. After the lower end of the steel ball 33 is located inside the upper end of the fixing ring 5, the right side of the probe tube 4 of the sensor contacts the button of the detection switch S1, and the internal contacts of the detection switch S1 are closed. In this way, the 220V power supply enters the power input terminal of the wireless charging transmitting module A1 (at the same time, the power supply will enter the power input terminal of the light-emitting diode VL after being stepped down and current-limited by the resistor R1, and the light-emitting diode VL is powered on and emits light to prompt the user that the device has entered the charging state). The wireless charging transmitting module A1 emits a wireless energy signal. After the wireless charging receiving module A2 (the outer end of the detection tube here can be marked with a color, and the staff can accurately insert the detection tube into the fixing slot 101 according to the prompted direction) receives the wireless energy signal, it converts it into a DC 5V power supply to charge the battery G1. After charging, the probe tube can be pulled out (when pulling out the probe tube to the left outer end, the fixing ring 5 will cause the steel ball to move upward against the elastic force of the spring during movement, and then the steel ball is located at the upper end of the non-fixing ring part of the probe tube, making it convenient to pull out the probe tube). Since after charging, the right side of the probe tube is separated from the contact switch and the internal contacts of the contact switch are open, in this way, the wireless charging transmitting module A1 will lose power and stop working. Therefore, automatic on / off control of the wireless charging transmitting module end can be realized, and on the basis of automatic control, the purpose of energy saving is also achieved. Figure 2 Among them, the light-emitting diode VL is a red light-emitting diode; the resistance value of the resistor R1 is 110K; the wireless charging transmitting module A1 and the wireless charging receiving module A2 body are finished products of wireless charging transmitting and receiving components with a power of 20W. The above components are mature industrial products, and this application will not elaborate on their working principles one by one.
