Description

Technical Field

[0001] The utility model provides a magnetic encoding horizontal sensor, which relates to the technical field of horizontal sensors. Background Art

[0002] An electric adjustment bracket fixes a communication device on a tower. In order to radiate the signal of the communication device to the best position and angle, it is necessary to adjust the azimuth angle and pitch angle of the device through the electric adjustment bracket. The detection and feedback of the position angle of the device require the use of a position sensor. The position sensor can sense the position or angle of the measured object and convert it into an available output signal; the most commonly used position sensor is a potentiometer sensor.

[0003] The existing potentiometer sensor has a contact connected to a mechanical shaft. The movement of the mechanical shaft can be rotational or slider type, which will cause the resistance value between the slider and the two end connections to change, thereby generating an electrical signal output. There is a proportional relationship between the actual tap position on the resistance track and its resistance value. However, the existing potentiometer sensor measures the position and motion state of an object through the resistance value, so its service life will be affected by the change of the resistance value. Especially when used for a long time in a high-temperature or high-humidity environment, the potentiometer sensor is prone to aging and damage, resulting in a decrease in measurement accuracy and ultimately affecting its service life.

[0004] Therefore, it is necessary to provide a non-contact magnetic encoding horizontal sensor with reduced wear. Summary of the Utility Model

[0005] In order to overcome the defect that the existing potentiometer sensor measures the position and motion state of an object through the resistance value, and the measurement accuracy will decrease when the potentiometer sensor ages and is damaged, the utility model provides a non-contact magnetic encoding horizontal sensor with reduced wear.

[0006] To achieve the above object, the embodiments of the utility model provide the following technical solutions: A magnetic encoding horizontal sensor includes an upper cover, a base, a PCBA board and a cable. The PCBA board is installed on the base, the upper cover is rotatably arranged on the base, the PCBA board is located inside the upper cover, the cable is fixedly connected to the bottom of the base, and the cable is electrically connected to the PCBA board. It further includes a permanent magnet and a magnetic encoder. The magnetic encoder is installed on the PCBA board, the permanent magnet is installed inside the upper cover, the permanent magnet is magnetically connected to the magnetic encoder, and a certain distance is maintained between the permanent magnet and the magnetic encoder.

[0007] As an improvement to the above solution, it further includes two mounting boxes installed on the upper cover. A condensing pipe and a heating pipe are respectively fixedly connected inside the two mounting boxes. Mounting frames are installed on both of the two mounting boxes, and a fan is installed on the mounting frame. Air ducts are connected and communicated on both of the two mounting boxes. A connecting pipe is connected and communicated on the upper cover. The connecting pipe is sleeved and communicated with the two air ducts. An electric ball valve is rotatably arranged inside the connecting pipe, and a control center is installed on the electric ball valve.

[0008] As an improvement to the above solution, it further includes a positioning plate installed on the upper cover. Two connecting rods are slidably arranged on the positioning plate. An anti-collision plate is fixedly connected to the two connecting rods together. Elastic members are wound around both of the two connecting rods. The elastic members are used to buffer the impact received by the anti-collision plate and reset it.

[0009] As an improvement to the above solution, it further includes a support frame installed on the connecting pipe. A display instrument is installed on the support frame. A temperature measuring rod is installed on the display instrument. The temperature measuring rod is electrically connected to the control center.

[0010] As an improvement to the above solution, a pointer is fixedly connected to the upper cover.

[0011] As an improvement to the above solution, a protective plate is rotatably arranged on the display instrument.

[0012] As an improvement to the above solution, an isolation net is installed at the air inlet of the mounting frame.

[0013] Compared with the prior art, the horizontal sensor provided by the embodiment of the present utility model has the following advantages: 1. The upper cover drives the permanent magnet to rotate, so that the relative positions of the N / S poles of the permanent magnet change, thereby changing the magnetic field distribution on the base. At this time, the magnetic encoder senses the magnetic field of the permanent magnet, and then measures the angular change of the object, achieving the effects of reducing wear, accurate measurement and extending the service life.

[0014] 2. By starting the fan to draw external air into the mounting box, and controlling the condensing pipe or the heating pipe to cool or refrigerate the air, and controlling the control center to control the electric ball valve to rotate, so that the connecting pipe and the corresponding air duct are communicated, and the air enters the inside of the upper cover, achieving the effects of regulating the temperature and reducing the influence of the temperature on the measurement.

[0015] 3. The anti-collision plate receives the collision to prevent the upper shell from colliding, so that the anti-collision plate slides along the positioning plate toward the side close to the upper cover through the connecting rod. At this time, the elastic member is compressed and deformed by the force. The impact is buffered by the elastic member. When the impact force disappears, the elastic member pushes the anti-collision plate to reset, achieving the effects of buffering the impact and protecting the upper shell.

[0016] 4. Detect the temperature of the usage scenario through the temperature measuring rod, and display the temperature through the display instrument. When the temperature measuring rod detects unsuitable temperature, send a command signal to the control center, and then control the electric ball valve to rotate to connect the connecting pipe with the corresponding air duct, so as to achieve the effect of measuring the temperature of the usage scenario.

The PCBA board 3 is installed on the top of the base 2 by means of bolt connection. The upper cover 1 is rotatably arranged on the base 2. The PCBA board 3 is located inside the upper cover 1. The cable 4 is fixedly connected to the bottom of the base 2, and the cable 4 is electrically connected to the PCBA board 3. It also includes a permanent magnet 5 and a magnetic encoder 6. The magnetic encoder 6 is installed on the top of the PCBA board 3 by means of bolt connection. The permanent magnet 5 is installed on the inner top of the upper cover 1 by means of welding. The permanent magnet 5 and the magnetic encoder 6 are magnetically connected, and a certain distance is maintained between the permanent magnet 5 and the magnetic encoder 6.

[0028] When an object drives the upper cover 1 to rotate, the upper cover 1 drives the permanent magnet 5 to rotate, so that the relative positions of the N / S poles of the permanent magnet 5 change, thereby changing the magnetic field distribution on the base 2. At this time, the magnetic encoder 6 senses the magnetic field of the permanent magnet 5, and then measures the angular change of the object relative to the reference direction. Through steps such as modeling the magnetic field distribution, detecting the magnetic field change, signal processing, and angle calculation, accurate angle information of the rotating component relative to the fixed component is obtained; Since the permanent magnet 5 and the magnetic encoder 6 adopt a non-contact structure, there is no friction between them, and they have high reliability and long service life.

[0034] When the temperature measuring rod 22 detects the temperature of the usage scenario, it is displayed on the display instrument 21. When the temperature measuring rod 22 detects an inappropriate temperature, it sends a command signal to the control center 14, and then controls the electric ball valve 15 to rotate so that the connecting pipe 13 communicates with the corresponding air duct 12.
