A gearbox 111 is fixedly mounted on the rack bracket 109, and the input end of the gearbox 111 is fixedly connected to the input gear 110. A pointer 112 is fixedly mounted on the output end of the gearbox 111. A dial 113 is fixedly mounted on the housing 114, and the dial 113 and the pointer 112 are rotatably matched. A buzzer 116 is also fixedly mounted on the housing 114, and the dial 113 is covered with a transparent cover 115, which is snapped onto the housing 1 14, the arc frame supporting magnetic block 122 is fixedly installed on the dial 113, the arc frame 119 is fixedly connected to the arc frame supporting magnetic block 122, the magnetic sheet 118 is slidably matched with the arc frame 119, the magnet 120 is slidably matched with the arc frame 119, and the limit block 117 is also fixedly installed on the dial 113, the limit block 117 is in contact with the magnetic sheet 118, the magnet 120 is magnetically matched with the arc frame supporting magnetic block 122, the magnetic sheet 118 is magnetically matched with the pointer 112, the detection chamber 102 is fixedly installed on the air inlet 101, and the air inlet 101 is fixedly installed on the ball valve 3.

[0028] like Figure 8-Figure 10 As shown, the energy recovery component includes a side panel 201, a turbine housing 202 is fixedly mounted on the side panel 201, a power disk 204 is rotatably mounted inside the turbine housing 202, the power disk 204 is connected to the generator, one end of the turbine housing 202 is connected to the ball valve 3, and an air intake port 203 is fixedly mounted on the other end of the turbine housing 202.

[0029] The working principle of the tank sealing detection device disclosed in the present invention is as follows: the user installs the air inlet 101 on the tank to be detected, connects the vacuum pump to the air inlet 203, opens the ball valve 3, and then starts the vacuum pump to evacuate the tank into a negative pressure state. When the pressure in the tank reaches the set value, close the ball valve 3, and then separate the vacuum pump from the air inlet 203. Figure 4 As shown, at the same time, the detection piston 103 moves downward under the action of atmospheric pressure, and at the same time drives the spring plate 104 to bend downward. At this time, the sliding block 105 will also move downward. The downward movement of the sliding block 105 will drive one end of the power arm 107 to swing downward. At this time, the other end of the power arm 107 will swing upward, and the arc rack 108 will also swing synchronously. The arc rack 108 makes a circular motion to drive the input gear 110 to rotate. The rotation of the input gear 110 will drive the pointer 112 to rotate through the gearbox 111. When the pressure reaches the set value, the pointer 112 rotates to contact the magnetic sheet 118, and the magnetic sheet 118 is adsorbed onto the pointer 112.

[0030] When the sealing of the tank is poor and the pressure leaks, the detection piston 103 will move upward, and synchronously, the pointer 112 will swing to the initial position. At this time, the pointer 112 will drive the magnetic sheet 118 to move synchronously, and the magnetic sheet 118 will drive the magnet 120 to move, and the magnet 120 will drive the trigger bar 121 to move. When the trigger bar 121 contacts the contact 123, the buzzer 116 is triggered to sound an alarm, indicating that the pressure leak exceeds the standard. It should be noted that the magnet 120 and the arc frame supporting magnetic block 122 repel each other, and the repulsive force between the magnet 120 and the arc frame supporting magnetic block 122 only provides the magnet 120 to return to Figure 8 As shown in the position, the magnetic force between the magnetic sheet 118 and the pointer 112 is greater than the maximum repulsive force when the magnet 120 and the arc-shaped frame supporting magnetic block 122 are close to each other. When the trigger bar 121 contacts the contact 123, the magnetic sheet 118 can no longer continue to move with the pointer 112. At this time, the magnetic sheet 118 is separated from the pointer 112, and the magnetic sheet 118 will return to its initial position under the action of the repulsive force between the magnet 120 and the arc-shaped frame supporting magnetic block 122.

[0031] When the test is completed, when the pressure in the tank needs to be balanced with the external atmospheric pressure, the ball valve 3 is slowly opened, and the external pressure enters the tank through the air inlet 203. Fig.10As shown, since air is a viscous fluid, the air will drive the power disk 204 to rotate, and then flow into the tank through the center hole. In this process, the power disk 204 will be subjected to the horizontal viscous force of the air along the tangential direction of the power disk 204, and the power disk 204 will rotate at this time. Because there is friction between the air attached to the surface of the power disk 204 and the power disk 204, the rotation of the power disk 204 will drive the air to rotate, and the rotation of the air will generate centrifugal force, because the shortest distance for the air flow is the straight-line distance from the air intake 203 to the center through hole of the turbine housing 202. At this time, the air is driven to rotate by the power disk 204, so the actual distance traveled by the air is a spiral path, that is, the path traveled by the air becomes longer, and the path traveled by the air on the power disk 204 becomes longer. Further, the power disk 204 rotates faster, and at the same time, the centrifugal force received by the air attached to the power disk 204 will be greater, so the density of the actual spiral path will also increase, so the friction will further increase until the rated power is reached. The rotation of the power disk 204 drives the generator to generate electricity, thereby recovering part of the electric energy consumed by the vacuum pump.
