The sensor housing is provided with a receiving cavity, the circuit board is arranged in the receiving cavity, the sensor housing is fixedly connected to a limit block, and the sensor device is fixedly connected to the pole switch pointer through the limit block. The device is fixed on the pole switch pointer and moves with the pointer. When the angle of the pointer changes, the angle detected by the sensor device changes accordingly. Through the set angle range corresponding to the opening and closing of the switch, the sensor outputs the corresponding angle signal or the opening and closing signal, thereby judging the status of the pole switch.

[0012] For easy installation, preferably, the side wall of the insulating shell is fixedly connected with a mounting plate, and both ends of the mounting plate are fixedly connected with a clamping plate by bolts.

[0013] Compared with the prior art, the utility model provides a posture sensor device for monitoring the status of a switch on a column, which has the following beneficial effects:

[0014] 1. The attitude sensor device for monitoring the status of the switch on the column generates airflow and wind force in the heat dissipation pipe, so that the external airflow quickly flows into the heat dissipation pipe from the air inlet groove, and then enters the protective shell from the heat dissipation pipe along the air guide pipe.

The posture sensor device for monitoring the status of the switch on the column can first filter the dust contained in the airflow through the vibration spring and the inclined filter, thereby reducing the friction loss of the dust-laden airflow on the sensor body. Secondly, the airflow will cause the filter to move horizontally and shake, so that the dust attached to the filter is shaken off and slides down the filter, thereby ensuring the use effect of the filter.

[0024] Example:

[0025] Reference Figure 1-Figure 5 , a posture sensor device for monitoring the state of a pole switch, comprising an insulating shell 1, a protective shell 2 and a sensor body 3, the protective shell 2 is fixed in the insulating shell 1, the sensor body 3 is fixed in the protective shell 2, the side wall of the insulating shell 1 is fixedly connected with a mounting plate 9, both ends of the mounting plate 9 are fixedly connected with a clamping plate 91 by bolts, the mounting plate 9 and the clamping plate 91 are fixed to the knife switch by bolts, so that when the knife switch of the pole switch is closed or opened, the sensor body 3 will move with the knife switch, at this time, the detection angle of the sensor body 3 will change accordingly, and the sensor body 3 will also output a switch-on signal according to the pre-set angle range corresponding to the switch-on, so as to quickly judge the state of the pole switch, without manual field observation, reducing manpower requirements, and improving the accuracy and timeliness of the monitoring results, and also comprising: the side wall of the protective shell 2 is connected with an air duct 21, the outer wall of the insulating shell 1 is provided with an air inlet groove 4, and a heat dissipation part for promoting the rapid flow of airflow is connected between the air inlet groove 4 and the air duct 21; wherein a shielding part for filtering dust is arranged in the air inlet groove 4.

[0026] Reference Figure 3-Figure 5, wherein the heat dissipation part includes a heat dissipation pipe 5, two ends of the heat dissipation pipe 5 are fixedly connected with the air guide pipe 21 and the air inlet groove 4 respectively, a driving motor 51 is fixedly connected inside the heat dissipation pipe 5, and a heat dissipation fan blade 52 is fixedly connected to the output shaft of the driving motor 51, an air outlet hole 22 is opened on the side of the protective shell 2 away from the air guide pipe 21, and three groups of air outlet holes 22 are arranged at equal intervals, an air outlet groove 6 is fixedly connected to the outer wall of the insulating shell 1, a shielding plate 61 is rotatably connected inside the air outlet groove 6, and a limiting strip 62 is fixedly connected inside the air outlet groove 6. When the driving motor 51 is not turned on for heat dissipation, the shielding plate 61 is blocked by the limiting strip 62 and is in a vertical state at most to block the air outlet groove 6, thereby effectively preventing external dust from passing through the outlet The air groove 6 is used for entering and exiting, which effectively improves the dust-blocking effect, and three groups of air outlet grooves 6 are arranged at equal intervals; the driving motor 51 is turned on to drive the heat dissipation fan blades 52 to rotate in the heat dissipation tube 5, thereby generating airflow and wind force in the heat dissipation tube 5, so that the external airflow quickly flows into the heat dissipation tube 5 from the air inlet groove 4, and then enters the protective shell 2 from the heat dissipation tube 5 along the air guide pipe 21. At this time, the airflow will take away the heat generated by the sensor body 3 during operation, and enter the insulating shell 1 from the air outlet 22, and then push the baffle plate 61 to flip outward, and then open the air outlet groove 6, so that the airflow with heat is discharged, thereby quickly dissipating the heat of the sensor body 3, and effectively improving the durability of the sensor body 3.

[0027] Reference Figure 4 , Figure 5 The shielding part includes a filter screen 7, which is slidably connected to the inner wall of the air inlet groove 4. Through the setting of the filter screen 7, the dust contained in the air flow will be filtered, which effectively improves the cleanliness of the heat dissipation air flow and reduces the friction loss of the air flow with dust on the sensor body 3, further improving the durability of the sensor body 3. The air inlet surface of the filter screen 7 is inclined, and vibration springs 71 are fixedly connected between the two ends of the filter screen 7 and the air inlet groove 4.

The rain shield box 8 can effectively prevent rainwater from being drawn into the process of heat dissipation and air intake, thereby improving the protection effect of the sensor body 3.

[0028] Reference Figure 1-Figure 5In the utility model, when in use, first fix the protective shell 2 in the insulating shell 1, then fix the sensor body 3 in the protective shell 2, and then arrange the mounting plate 9 and the clamping plate 91 on both sides of the knife switch of the pole switch, and fix the mounting plate 9 and the clamping plate 91 on the knife switch by bolts, so that when the knife switch of the pole switch is closed or opened, the sensor body 3 will move with the knife switch, and the detection angle of the sensor body 3 will change accordingly. Through the pre-set angle range corresponding to the opening and closing of the switch, the sensor body 3 will also output the opening and closing signal, so as to quickly judge the state of the pole switch, without manual field observation, reducing the manpower demand and improving the accuracy and timeliness of the monitoring results;

[0029] And during the operation of the sensor body 3, the driving motor 51 is turned on to drive the heat dissipation fan blades 52 to rotate in the heat dissipation tube 5, thereby generating airflow and wind force in the heat dissipation tube 5, so that the external airflow quickly flows into the heat dissipation tube 5 from the air inlet groove 4, and then enters the protective shell 2 from the heat dissipation tube 5 along the air guide pipe 21. At this time, the airflow will take away the heat generated by the sensor body 3 during operation, and enter the insulating shell 1 from the air outlet 22. Then, as the airflow continuously enters the insulating shell 1, the air pressure in the insulating shell 1 will increase, thereby pushing the baffle plate 61 to flip outward, and then opening the air outlet groove 6, so that the airflow with heat is discharged. In this way, the sensor body 3 can be quickly cooled, and the durability of the sensor body 3 can be effectively improved. When the airflow flows in from the air inlet slot 4, the dust contained in the airflow can be filtered through the setting of the filter 7, which effectively improves the cleanliness of the heat dissipation airflow and reduces the friction loss of the dust-laden airflow on the sensor body 3, further improving the durability of the sensor body 3. When the airflow continuously passes through the filter 7, the setting of the vibration spring 71 can cause the filter 7 to move horizontally and shake, so that the dust attached to the filter 7 is shaken off and slides down the filter 7, thereby ensuring the use effect of the filter 7.
