[0024] In the disclosed embodiment, the rod body of the adjusting rod 202 is provided with a thread on the outside, and the adjusting rod 202 is screwed to the inside of the positioning seat 203 through the rod body thread. In use, the display screen 103 is installed on the screen mounting frame 205. The use angle of the display screen 103 can be changed by changing the pitch angle of the screen mounting frame 205, so that the inclination angle of the display screen 103 can be adjusted according to the actual setting height of the monitoring component 1 to facilitate the observation and recording of data by ground personnel. A positioning rack 2031 is provided on the side of the positioning seat 203, and a positioning gear 2051 is provided on the rotating shaft of the screen mounting frame 205. Under the action of the connecting tension spring 2062, the gear teeth of the positioning rack 2031 and the positioning gear 2051 are engaged and transmitted, and the transmission between the positioning rack 2031 and the positioning gear 2051 is The resistance is not enough to cause the connecting tension spring 2062 to deform, and there are two adjustment methods. One is to achieve regulation by controlling the forward and reverse rotation of the adjusting motor 204. In this method, when the adjusting motor 204 rotates, it can drive the adjusting rod 202 to rotate synchronously. When the adjusting rod 202 rotates, it can drive the positioning seat 203 to move up and down inside the connecting seat 201 through the rod body thread. When the positioning seat 203 moves, the positioning rack 2031 can drive the screen mounting frame 205 to rotate through the positioning gear 2051 to change the pitch angle. The second is to manually directly rotate the adjusting rod 202 to achieve it. This method is suitable for regulation when the power is off during maintenance. The use angle of the display screen 103 can be adjusted according to actual needs and the setting height of the monitoring component 1, and it is extremely flexible and adaptable.

[0025] In the embodiment of the present disclosure, a connecting tension spring 2062 is provided inside the positioning column 2061, and the two ends of the connecting tension spring 2062 are respectively fixedly connected to the inside of the positioning column 2061 and the inside of the connecting seat 201. In use, since the moving distance of the positioning seat 203 inside the track groove 2011 is limited, the adjustment range of the screen mounting frame 205 is also limited, but the connecting component 2 can adjust the adjustment range of the screen mounting frame 205. For example, when the screen mounting frame 205 is used vertically at zero degrees and the adjustment range is between positive forty-five degrees and negative forty-five degrees, when the screen mounting frame 205 is pulled, the connecting column 206 can be driven to move synchronously and the connecting tension spring 2062 can be lengthened, releasing the positioning The meshing relationship between the teeth of the positioning rack 2031 and the positioning gear 2051, that is, at this time, the screen mounting frame 205 loses the positioning function of the use angle of the screen mounting frame 205 when the adjusting rod 202 is matched with the thread and the positioning seat 203. Thereafter, the screen mounting frame 205 can be manually rotated to adjust the initial use angle of the screen mounting frame 205, that is, the screen mounting frame 205 is changed from a vertical state, and its initial state is no longer zero degrees, so that the effective adjustment range will also change. After the adjustment is completed, after the screen mounting frame 205 is released, the connecting component 2 restores the positioning state of the screen mounting frame 205 under the action of the connecting tension spring 2062 for subsequent adjustment and use.

[0026] The specific usage and function of this embodiment are as follows:

[0027] In the utility model, after the monitoring component 1 is installed, the data such as wind speed, wind direction and the amount of dust in the environment can be monitored, and the monitoring data can be displayed on the display screen 103 in real time. The display screen 103 is installed on the screen mounting frame 205. The use angle of the display screen 103 can be changed by changing the pitch angle of the screen mounting frame 205, so that the inclination angle of the display screen 103 can be adjusted according to the actual setting height of the monitoring component 1, so as to facilitate the observation and recording of data by ground personnel, and there are two adjustment methods, one of which is to control the forward and reverse rotation of the adjustment motor 204 to achieve The present regulation is carried out. In this mode, when the regulating motor 204 rotates, the regulating rod 202 can be driven to rotate synchronously. When the regulating rod 202 rotates, the positioning seat 203 can be driven to move up and down inside the connecting seat 201 through the rod body thread. When the positioning seat 203 moves, the positioning rack 2031 can drive the screen mounting frame 205 to rotate through the positioning gear 2051 to change the pitch angle. The second is to manually directly rotate the regulating rod 202 to achieve it. This mode is suitable for regulation in the case of power failure for maintenance. The display screen 103 can be adjusted according to actual needs and the setting height of the monitoring component 1. The angle is used for adjustment. Since the moving distance of the positioning seat 203 in the track groove 2011 is limited, the adjustment range of the screen mounting frame 205 is also limited. However, the connecting component 2 can adjust the adjustment range of the screen mounting frame 205. For example, when the screen mounting frame 205 is used vertically at zero degrees and the adjustment range is between positive forty-five degrees and negative forty-five degrees, when the screen mounting frame 205 is pulled, the connecting column 206 can be driven to move synchronously and the connecting tension spring 2062 can be lengthened, thereby releasing the meshing relationship between the positioning rack 2031 and the positioning gear 2051. That is, at this time, the screen mounting frame 205 is When the frame 205 loses the positioning function of the use angle of the screen mounting frame 205 by the matching relationship between the adjusting rod 202 and the positioning seat 203, the screen mounting frame 205 can be manually rotated thereafter, so as to adjust the initial use angle of the screen mounting frame 205, that is, the screen mounting frame 205 is changed from a vertical state, and its initial state is no longer zero degrees, so that the effective adjustment range will also change. After the adjustment is completed, after the screen mounting frame 205 is released, the connecting component 2 restores the positioning state of the screen mounting frame 205 under the action of the connecting tension spring 2062 for subsequent adjustment and use.

[0028] In another embodiment, the cross-sectional shape of the seat body of the positioning seat 203 is "T"-shaped, and a track groove 2011 is provided inside the connecting seat 201, the positioning seat 203 is inserted into the inside of the track groove 2011, and one end of the connecting column 206 is provided with a positioning column 2061 with a regular polygonal cross-section, and a positioning groove 2012 is provided inside the connecting seat 201, and the positioning column 2061 is inserted into the inside of the positioning groove 2012. This design limits the moving trajectory of the positioning seat 203 and the connecting column 206, so that the two will not be skewed or twisted during adjustment and use, causing the device to get stuck and fail, and the use is stable.
