[0015] An application method of heavy pollution control PID monitoring equipment:

[0016] S1: When in use, the user adjusts the adjustable hand-held bracket and then holds the adjustable hand-held bracket to place the main body of the PID monitoring device at the position to be monitored, or fixes the main body of the PID monitoring device at the position to be monitored by an external fixing component;

[0017] S2: When the PID monitoring device is monitoring, the gas at the monitoring position enters from the air inlet. When the outside air enters from the air inlet, the gas first passes through the corresponding port and then passes through the filter element corresponding to the air inlet to filter out dust and impurities before entering the PID monitoring device for detection;

[0018] S3: After the gas is processed by the filter mesh, it enters from the air inlet, causing the follower impeller to rotate, and then the transmission rod drives the bevel gear set to rotate the follower rod, and then the follower rod drives the collar to make the connecting arm perform a circular motion around the collar. When it performs a circular motion, the bristles at the bottom of the moving block rub against the filter mesh at the corresponding opening, thereby achieving a cleaning effect on the dust and the like at the filter mesh. At the same time, when the follower rod rotates, the driving plate drives the shaft body to rotate around the gear ring, and then the driven gear and the gear ring on the shaft body cooperate to make the shaft body rotate, and then the push block rotates, so that the push block pushes the L-shaped rod reciprocatingly, and the L-shaped rod makes the moving block reciprocate in the horizontal opening, so that the bristles perform linear reciprocating motion during the rotation process, thereby improving the cleaning quality of the filter mesh;

[0019] S4: At the same time, when the filter element at the corresponding air inlet is seriously clogged, the amount of gas entering from the air inlet becomes smaller, so that the pressure inside the air inlet becomes larger, so that the movable detection rod moves outward, so that the contact element contacts the sensor, and then the sensor sends a signal to make the rotating device drive the gear set to make the follower cylinder rotate a certain angle, so that the next set of filter elements corresponds to the air inlet;

[0020] S5: After long-term use, the filter element can be removed from the arc block for maintenance or replacement by removing the sealing plate and pulling the T-shaped rod to move outward.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1) When the PID monitoring device body is monitoring, the present invention allows the gas at the monitoring position to enter from the air inlet. When the external gas enters from the air inlet, the gas first passes through the corresponding port and then passes through the filter element corresponding to the air inlet to filter out dust and impurities before entering the PID monitoring device body for detection, thereby greatly avoiding the adsorption of external dust and impurities, ensuring the long-term monitoring quality and monitoring accuracy of the PID monitoring device body, and extending the service life of the PID monitoring device body;

[0023] 2) After the gas is processed by the filter mesh, it enters from the air inlet, causing the follower impeller to rotate, and then the transmission rod drives the bevel gear set to rotate the follower rod, and then the follower rod drives the collar to make the connecting arm perform a circular motion around the collar. When it performs a circular motion, the bristles at the bottom of the moving block rub against the filter mesh at the corresponding opening, thereby achieving a cleaning effect on the dust and the like at the filter mesh. At the same time, when the follower rod rotates, the driving plate drives the shaft body to rotate around the gear ring, and then the driven gear and the gear ring on the shaft body cooperate to make the shaft body rotate, and then the push block rotates, so that the push block reciprocates and pushes the L-shaped rod, and the L-shaped rod causes the moving block to reciprocate in the horizontal opening, so that the bristles perform linear reciprocating motion during the rotation process, thereby improving the cleaning quality of the filter mesh;

[0024] 3) In the present invention, when the filter element at the corresponding air inlet is seriously clogged, the amount of gas entering from the air inlet becomes smaller, causing the pressure inside the air inlet to increase, thereby causing the movable detection rod to move outward, causing the contact element to contact the sensor, and then the sensor sends a signal to cause the rotating device to drive the gear set to cause the follower cylinder to rotate a certain angle, so that the next set of filter elements corresponds to the air inlet, thereby ensuring the stability of the PID monitoring equipment body during long-term use.

A heavy pollution control PID monitoring device according to claim 1, characterized in that: T-shaped rods (26) are symmetrically and movably inserted on both sides of the arc block (25), and the outer wall of the filter element (24) is provided with an insertion hole that matches the T-shaped rod (26), and the outer wall of the T-shaped rod (26) is sleeved with a return spring.

4. The application method of a heavy pollution control PID monitoring device according to any one of claims 1 to 3 is characterized in that: S1: During use, a user adjusts the adjustable hand-held bracket (12) and then holds the adjustable hand-held bracket (12) so that the PID monitoring device body (11) is located at the position to be monitored, or fixes the PID monitoring device body (11) through an external fixing component so that the PID monitoring device is located at the position to be monitored; S2: When the PID monitoring device body (11) is monitoring, it allows the gas at the monitoring position to enter from the air inlet (13). When the outside air is allowed to enter from the air inlet (13), the gas first passes through the corresponding port (211) and then passes through the filter element (24) corresponding to the air inlet (13) to filter out dust and impurities before entering the PID monitoring device body (11) for detection; S3: After being processed by the filter element (24), the gas enters the air inlet (13), causing the follower impeller (220) to rotate, thereby causing the transmission rod (219) to drive the bevel gear set (218) to rotate the follower rod (212), and then the follower rod (212) drives the collar to cause the connecting arm (29) to perform a circular motion around the collar. When the collar performs a circular motion, the bristles (222) at the bottom of the moving block rub against the filter element (24) at the corresponding opening (211), thereby cleaning the dust and the like at the filter element (24). When the follower rod (212) rotates, the driving plate drives the shaft body to rotate around the gear ring (213), so that the driven gear (214) and the gear ring (213) on the shaft body cooperate to cause the shaft body to rotate, and then the push block (215) rotates, so that the push block (215) pushes the L-shaped rod (216) back and forth, and the L-shaped rod (216) causes the moving block to move back and forth in the horizontal opening, so that the bristles (222) move linearly back and forth during the rotation process, thereby improving the cleaning quality of the filter element (24); S4: At the same time, when the filter element (24) at the corresponding air inlet (13) is seriously clogged, the amount of gas entering from the air inlet (13) decreases, causing the pressure inside the air inlet (13) to increase, thereby causing the movable detection rod (2211) to move outward, causing the contact element to contact the sensor (2212), and then the sensor (2212) sends a signal so that the rotating device drives the gear set (23) to rotate the follower cylinder (22) by a certain angle, so that the next set of filter elements (24) corresponds to the air inlet (13); S5: After long-term use, the filter element (24) can be removed from the arc block (25) for maintenance or replacement by removing the sealing plate (27) and pulling the T-shaped rod (26) to move outward.
