Referring to fig. 1-3, the present invention provides a technical solution:

the utility model provides a concrete air discharge shaft, includes bottom plate 1, and 1 upside of bottom plate is equipped with the wall of a

well

2, and 2 middle parts of the wall of a well are equipped with

pipeline

3, and 3 middle part circumference outer walls one side of pipeline are equipped with valve 4, its characterized in that: draw-in groove 201 has been seted up to 2 upsides of the wall of a well, the inside card of draw-in groove 201 is equipped with well

lid

5, 5 upside middle part symmetries of well lid are equipped with two handles 6, exhaust chamber 501 has all been seted up to the 5 inside left and right sides of well lid, 5 bottom surfaces left and right sides of well lid have all been seted up and have all been equipped with quick-witted case 502, the inside motor 503 that is equipped with of machine case 502, the motor 503 output shaft passes quick-witted case 502 inner wall and extends to exhaust chamber 501 inside and has cup jointed sealed dish 504, two spacing grooves 505 have been seted up to sealed dish 504 circumference outer wall symmetry, sealed dish 504 circumference outside is equipped with two sealed pieces 506, sealed piece 506 outside lower extreme is connected with arc ring 507 through the round pin hub rotation, exhaust chamber 501 circumference inner wall symmetry intercommunication has two blast pipes 508, the inside bottom surface of exhaust chamber 501 is close to the edge and has seted up ring channel 509. The closely cooperate between the structure for the device is when using, through sealed dish 504 rotation, makes the inside gas of exhaust well dilute to the external world through the inside discharge of exhaust chamber 501, and has avoided the valve 4 periphery to reveal in the exhaust well, has avoided the emergence of potential safety hazard.

Specifically, the limiting groove 505 is slidably connected with the sealing block 506. The design of the limiting groove 505 enables the limiting groove to drive the sealing block 506 to rotate, and meanwhile, the limiting groove can adapt to the eccentric distance of the sealing block 506, so that the sealing block can be always kept in a sealing state.

Further, the arcuate ring 507 is slidably coupled to the annular groove 509. So that the arc-shaped ring 507 can only rotate in the annular groove 509, and the outer end of the sealing block 506 can always keep contact and sealing with the inner wall of the exhaust cavity 501.

Still further, the seal disc 504 is arranged in an eccentric structure, and the size of the seal disc 504 and the size of the seal block 506 are matched with the inner diameter of the exhaust cavity 501. The inside of the exhaust cavity 501 is sealed, when the sealing disc 504 rotates eccentrically, the space on one side inside the exhaust cavity 501 is increased to form negative pressure to suck the gas inside, and when the sealing disc rotates to the other side, the space can be reduced to discharge the gas inside the exhaust cavity 501 to the outside.

Furthermore, the outer end of one of the exhaust pipes 508 extends to the outside through the inner wall of the exhaust chamber 501, and the outer end of the other exhaust pipe 508 extends to the inside of the well wall 2 through the inner wall of the exhaust chamber 501. So that the gas inside can reach the outside.

The working principle is as follows: when this concrete air discharge well is required to exhaust, firstly, supply power through the inside battery that inlays of well lid 5, make motor 503 output shaft rotate through the controller, because motor 503 output shaft passes quick-witted case 502 inner wall and extends to the inside of exhaust chamber 501 and cup joints sealed dish 504, and sealed dish 504 is eccentric structure setting, the size of a dimension and exhaust chamber 501 internal diameter looks adaptation of sealed dish 504 and sealed piece 506, make the inside sealed state that forms of exhaust chamber 501, when sealed dish 504 carries out eccentric rotation, because sealed dish 504 circumference outer wall symmetry has seted up two spacing grooves 505, and spacing groove 505 and sealed piece 506 sliding connection, the design of spacing groove 505, it can drive sealed piece 506 and rotate to make it, and simultaneously, can adapt to the eccentric distance of sealed piece 506, and simultaneously, arc ring 507 and ring groove 509 sliding connection. Make the arc ring 507 can only rotate in ring channel 509 to make the outer end of seal block 506 can remain throughout and exhaust chamber 501 inner wall contact seal, thereby when seal block 506 carries out the eccentric rotation, make the space increase of the inside one side of exhaust chamber 501 form the negative pressure and inhale inside gas, when rotating the opposite side, the space can reduce the gas discharge external world with the inside of exhaust chamber 501.
