Detailed Description
In order to make the aforementioned and other features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
As shown in fig. 1-2, an automatic drainage device comprises a closed box body 1, wherein one side of the bottom of the box body is provided with a water inlet pipe 2, the other opposite side is provided with a water outlet pipe 3, the middle part in the box body is provided with a floating ball 4 positioned above the water inlet pipe, the top of the floating ball is provided with a front pin shaft 5 and a rear pin shaft, the front pin shaft drives a valve 6 on the water outlet pipe to lift and open through a first connecting rod mechanism, the rear pin shaft drives a vertical air pressure plate 7 on the side of the top of the box body to lift through a second connecting rod mechanism, and the air pressure plate is used; when the valve is closed, a through-flow gap 9 is formed between the bottom end of the valve and the inner wall of the water outlet pipe; the water inlet pipe is connected with the flue.
The embodiment of the utility model provides an in, the vertical bottom open-ended drum 10 that has set firmly in box top, the floater top sets firmly a coaxial round bar 11 that inserts the drum inside, the front side perpendicular to axial of round bar has set firmly preceding round pin axle, the rear side perpendicular to axial of round bar has set firmly the back round pin axle, the vertical preceding gib block 12 that offers to be used for inlaying the round pin axle before establishing of the front side of drum, the vertical back gib block of offering to be used for inlaying the back round pin axle of establishing of the back of drum, preceding round pin axle is coaxial with the back round pin axle.
The embodiment of the utility model provides an in, first link mechanism includes that the middle part articulates the first connecting rod 13 on the box, the left end of first connecting rod is articulated through the groove strip and preceding round pin axle, the right-hand member of first connecting rod articulates there is downwardly extending's second connecting rod 14, the bottom of second connecting rod articulates on the groove strip of third connecting rod 15 right-hand member, the middle part of third connecting rod articulates on the box, the left end of third connecting rod is articulated through the round pin axle of groove strip with the valve top, the valve is vertical to be inserted and to be established on outlet pipe week portion slot and perpendicular with the outlet pipe axis.
The embodiment of the utility model provides an in, the second link mechanism includes that the middle part articulates the fourth connecting rod 16 on the box, and the right-hand member of fourth connecting rod is through the channel bar articulated with the back round pin axle, and the left end of fourth connecting rod is through the channel bar articulated with the round pin axle of aerostatic press bottom.
The embodiment of the utility model provides an in, the box is inside to set firmly a vertical curb plate 17 at the blow vent side, forms between vertical curb plate and the vertical face of blow vent place to be used for inserting the slot of establishing the atmospheric pressure board, also is equipped with the gas pocket 18 coaxial with the blow vent on the vertical curb plate.
The working method of the automatic drainage device comprises the following steps: (1) when the water level exceeds the water inlet pipe, the water level rises to the position of the floating ball in the box body, the buoyancy is increased, the floating ball rises to drive the front pin shaft and the rear pin shaft to rise, the fourth connecting rod rotates anticlockwise around the middle point, the air pressure plate descends to open the air vent, the box body is communicated with the outside at the moment, and the internal air pressure and the external air pressure are balanced; the first connecting rod rotates clockwise around the middle point, the second connecting rod descends, the third connecting rod rotates clockwise around the middle point, the ascending flow area of the valve is increased, water in the box body is discharged along the water outlet pipe, and the pipeline is not easy to block; (2) when the water level 19 is lower than the water inlet pipe, the water level is positioned below the floating ball in the box body, the vent hole and the valve can not be opened, water is discharged along the through-flow gap, gas exchange can not be realized inside and outside, thus internal toxic gas can not be leaked, and the vent hole and the valve can be opened only through the floating ball when the water flow is too large. Because the outside atmospheric pressure of flue is bigger, and the water level is withstood, is difficult to discharge from the outlet pipe, so we have adopted a valve, have the through-flow clearance between valve bottom and the outlet pipe inner wall when the valve is closed, also can say that a safeties, if rivers can normally discharge from the through-flow clearance, the blow vent can not be opened, inside and outside can't accomplish gas exchange, can guarantee like this that inside toxic gas can not leak, only can open when rivers are not discharged, at this moment the water level has surpassed the inlet tube, the water inlet liquid seal, can not do gas exchange equally.
The present invention is not limited to the above preferred embodiments, and any one can derive other automatic drainage devices of various forms according to the teaching of the present invention. All the equivalent changes and modifications made according to the claims of the present invention shall fall within the scope of the present invention.
