As shown in fig. 8-10, the energy recovery assembly comprises a side panel 201, a turbine housing 202 is fixedly mounted on the side panel 201, a power disc 204 is rotatably matched with the turbine housing 202, the power disc 204 is connected with a generator, one end of the turbine housing 202 is communicated with a ball valve 3, and an air suction port 203 is fixedly mounted at the other end of the turbine housing 202.
The invention discloses a tank tightness detection device, which has the following working principle: the user installs the air inlet 101 on the tank to be detected, connects the vacuum pump with the air suction port 203, opens the ball valve 3, then starts the vacuum pump, pumps the tank into a negative pressure state, closes the ball valve 3 when the pressure in the tank reaches a set value, and then separates the vacuum pump from the air suction port 203. As shown in fig. 4, at the same time, the detecting piston 103 moves downward under the action of atmospheric pressure, and drives the spring plate 104 to bend downward, at the same time, the sliding block 105 also moves downward, the sliding block 105 moves downward, and then one end of the power arm 107 swings downward, at the same time, the other end of the power arm 107 swings upward, the arc-shaped rack 108 also follows the swing synchronously, the arc-shaped rack 108 moves in an arc manner and drives the input gear 110 to rotate, the input gear 110 rotates and drives the pointer 112 to rotate through the gearbox 111, when the pressure reaches a set value, the pointer 112 rotates to be in contact with the magnetic sheet 118, and the magnetic sheet 118 is adsorbed onto the pointer 112.
When the tightness of the tank is poor, and the pressure leaks, the detecting piston 103 moves upwards, synchronously, the pointer 112 swings towards the initial position, at this time, the pointer 112 drives the magnetic sheet 118 to move synchronously, the magnetic sheet 118 drives the magnet 120 to move, the magnet 120 drives the touch spring 121 to move, when the touch bar 121 contacts the contact 123, the buzzer 116 is triggered to give an alarm, the pressure leakage is prompted to exceed the standard, it is noted that the magnet 120 and the arc-shaped frame supporting magnetic block 122 repel each other, and the repulsive force of the magnet 120 and the arc-shaped frame supporting magnetic block 122 only provides the magnet 120 to restore to the position shown in fig. 8, and the magnetic force of 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, when the touch bar 121 contacts the contact 123, the magnetic sheet 118 cannot move continuously along with the pointer 112, at this time, the magnetic sheet 118 is separated from the pointer 112, and the initial position is restored under the repulsive force of the magnet 120 and the arc-shaped frame supporting magnetic block 122.
When the pressure in the tank body and the external atmospheric pressure need to be balanced after the detection is completed, the ball valve 3 is slowly opened, at this time, the external pressure enters the tank body through the air suction port 203, as shown in fig. 10, because the air is a viscous fluid, at this time, the air drives the power disc 204 to rotate, and then flows into the tank body through the central hole, in the process, the power disc 204 can receive the horizontal viscous force of the air along the tangential direction of the power disc 204, at this time, the power disc 204 can rotate, and because friction exists between the air attached to the surface of the power disc 204 and the power disc 204, the rotation of the power disc 204 drives the air to rotate, the air rotation generates centrifugal force, and because the closest distance of the air flow is the straight line distance from the air suction port 203 to the central through hole of the turbine housing 202, at this time, the air is driven by the power disc 204 to rotate, so that the path of the air actually runs is a spiral path, that is longer, the path of the air running on the power disc 204 rotates faster, and at the same time, the centrifugal force of the air attached to the power disc 204 is larger until the actual spiral path is more dense, and the friction density is increased, and the rated power is further reached. Rotation of the power disc 204 drives the generator to generate electricity, thereby recovering the electric energy consumed by the partial vacuum pump.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
