The other mounting hole is welded with a fixed pipe 8 in communication with the air supplement pipeline 2. The circumferential inner wall of the fixed pipe 8 is provided with a limiting groove 17. A piston is slidably connected in the limiting groove 17. The top end of the piston is welded with a sliding rod 5.

[0022] The outer side of the slide rod 5 is fixed with a sliding frame 10 through bolts, the bottom of the sliding frame 10 is welded with two springs 14, and the springs 14 are fixed with the protruding blocks 3, the top of the protruding blocks 3 is welded with two guide rods 7, the two guide rods 7 are welded with a fixed ring 12, and the slide rod 5 passes through the fixed ring 12, the bottom of the fixed ring 12 is fixed with two third induction sensors 13 through bolts, the sliding frame 10 is fixed with two second induction sensors 11 penetrating the sliding frame 10 through bolts, the top of the fixed pipe 8 is fixed with two first induction sensors 9 through bolts, the pressure of the gas in the air supplement pipeline 2 is proportional to the stretching force of the spring 14, when the air pressure is small, the pressure of the air pressure is not proportional to the stretching force of the spring 14, and the force for shrinking the spring 14 is not enough, so that the spring 14 in the stretching state pulls the sliding frame 10 to move downwards along the guide rod 7, the sliding frame 10 drives the slide rod 5 to move into the limiting groove 17, and the slide rod 5 drives the piston to move downwards, when the sliding frame 10 moves downwards to the second induction sensor 11 and the first induction sensor 9 are in contact, the first induction sensor 9 sends a signal to the electromagnetic valve 6, so that the electromagnetic valve 6 is opened, the air supplement pipeline 2 in the communication pipe 4 is used for conveying the gas to increase the pressure of the gas, and since the pressure of the gas in the air supplement pipeline 2 gradually increases, the slide rod 5 is pushed upwards under the action of the gas pressure, the slide rod 5 drives the sliding frame 10 to move upwards, and the sliding frame 10 lengthens the spring 14, when the sliding frame 10 moves upwards to the second induction sensor 11 and the third induction sensor 13 are in contact, the third induction sensor 13 sends a signal to the electromagnetic valve 6, so that the electromagnetic valve 6 is closed, and the communication pipe 4 does not convey the gas into the air supplement pipeline 2, so that the air supplement can be automatically started and stopped according to the size of the air pressure, the waste of energy is reduced, and the energy consumption is saved.

[0023] In the utility model, the first induction sensor 9 and the third induction sensor 13 are electrically connected with the electromagnetic valve 6, the second induction sensor 11 is electrically connected with the first induction sensor 9 and the third induction sensor 13, the two guide rods 7 are arranged in the two springs 14 respectively, the guide rod 7 passes through the sliding frame 10, the limiting ring 18 for resisting the piston is fixed at the position at the bottom in the limiting groove 17 through bolts, when the sliding frame 10 moves downwards to the second induction sensor 11 and the first induction sensor 9 are in contact, the limiting ring 18 resists the piston, thereby assisting the support of the slide rod 5, the annular groove 15 is formed in the position above the limiting groove 17 in the fixed pipe 8, the sealing ring 16 for sealing the gap between the slide rod 5 and the fixed pipe 8 is bonded in the annular groove 15, the sealing ring 16 seals the gap between the slide rod 5 and the fixed pipe 8, thereby avoiding the leakage of the gas in the air supplement pipeline 2 from the gap between the slide rod 5 and the fixed pipe 8, and the sealing property of the air supplement device is improved.

[0024] The working principle is that when the air pressure is small, the air pressure is not proportional to the stretching force of the spring 14, and the force is not enough to offset the contraction of the spring 14, so the spring 14 in the stretching state pulls the sliding frame 10 to move downward along the guide rod 7, the sliding frame 10 drives the sliding rod 5 to move into the limiting groove 17, the sliding rod 5 drives the piston to move downward, when the sliding frame 10 moves downward to the second inductive sensor 11 and the first inductive sensor 9 is in contact, at this time the first inductive sensor 9 sends a signal to the electromagnetic valve 6, so as to open the electromagnetic valve 6 to transport the gas in the air supplement pipeline 2 in the communication pipe 4 to increase the pressure of the gas, at the same time the limiting ring 18 resists the piston, thereby assisting the support of the sliding rod 5, and because the pressure of the gas in the air supplement pipeline 2 gradually increases, under the action of the gas pressure, the sliding rod 5 is pushed upward, the sliding rod 5 drives the sliding frame 10 to move upward, the sliding frame 10 elongates the spring 14, when the sliding frame 10 moves upward to the second inductive sensor 11 and the third inductive sensor 13 is in contact, at this time the third inductive sensor 13 sends a signal to the electromagnetic valve 6, so as to close the electromagnetic valve 6, so that the communication pipe 4 does not transport the gas into the air supplement pipeline 2, at the same time the pressure of the gas supports the sliding rod 5 and the pressure of the gas is proportional to the stretching force of the spring 14, so that the sliding frame 10 cannot move downward under the action of the force of the spring 14, thereby the automatic start-stop air supplement according to the size of the air pressure can be realized, the waste of energy is reduced, and the energy consumption is saved.

For example, it can be fixed connection, detachable connection, or integral structure; it can be mechanical connection or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or internal communication between two devices, elements or components. Those skilled in the art can understand the specific meaning of the above terms in the present application according to the specific circumstances.
