The ball distributing device is also arranged in the ball storage barrel 1 and comprises a rotating base 4 which takes the circle center of the bottom surface of the ball storage barrel 1 as a shaft for rotating, a ball distributing driving plate 5 fixed on the inner wall of the ball storage barrel 1 and a ball distributing motor 6 used for driving the rotating base 4.
The ball outlet of the bottom surface of the ball storage barrel 1 is close to the side wall, similarly, the ball separating port 7 on the rotating base 4 is also close to the side wall, and the electric piston cavity 2 is also connected to the position far away from the center of the ball storage barrel 1, so that the position is reserved for the ball separating motor 6.
The ball outlet, the ball inlet, the ball distributing port 7 and the ball distributing dial 5 are matched with the ball discharging ball to be thrown in a rotating mode, but the ball discharging port, the ball distributing port and the ball distributing dial are larger in size, so that the ball discharging balls are prevented from being clamped inside.
The ball distributing dial 5 is positioned right above the ball outlet, and the height of the ball distributing dial 5 is consistent with that of the rotary base 4, so that the ball distributing opening 7 can be covered when the ball distributing opening 7 rotates to the ball outlet.
As shown in fig. 5, when the balls are separated, firstly the ball separating port 7 and the ball outlet are staggered, one row of balls to be soaked falls into the ball separating port 7, and the bottom of the ball storing barrel 1 is the bottom surface, so that the balls cannot fall, and the ball separating port 7 is matched with the row of balls to be soaked, wherein only one row of balls to be soaked can be obtained.
Then the ball distributing port 7 rotates towards the ball outlet, redundant foam volleyballs can be blocked by the ball distributing drive plate 5, when the ball distributing port 7 rotates to the position of the ball outlet, the ball distributing drive plate 5 is blocked on the ball distributing port 7 to prevent the redundant foam volleyballs from entering the ball distributing port, and the foam volleyballs in the ball distributing port 7 fall into the electric piston cavity 2 through the ball outlet and the ball inlet.
The ball throwing pipeline is sequentially connected with an upper ball valve 20 and a lower ball valve 9 from top to bottom, the ball throwing pipeline between the upper ball valve 20 and the lower ball valve 9 is a pressure detection section, and the pressure detection section is respectively connected with an emptying port 10 and a middle bin pressure sensor 8.
The upper ball valve 20 and the lower ball valve 9 are in a closed state initially, when a ball is to be thrown, the upper ball valve 20 is opened, the foam volleyballs enter a ball throwing pipeline and then fall on the lower ball valve 9, namely, in a pressure detection section, and at the moment, the pressure in the pressure detection section is zero.
The vent 10 is an external pipeline when foreign matters or other wells need to be vented in the pit, the vent 10 is opened to vent the wells, and the vent is closed during normal pitching operation.
Closing the upper ball valve 20, opening the lower ball valve 9, enabling the foam volleyball to fall into the well, wherein the pressure in the pressure detection section is high pressure in the well, and the pressure in the well is always kept to be isolated from the part of the ball storage barrel 1 above the pressure detection section.
The electric piston cavity 2 is also connected with an exhaust elbow 11, and the exhaust elbow 11 is positioned above the ball throwing pipeline.
When throwing the ball again, because pressure is high pressure in the pit in the pressure detection section, the bubble volleyball does not well fall into the pressure detection section, consequently opens ball valve 20, and high-pressure gas discharges through exhaust elbow 11, and the pressure detection section pressure release finishes, the follow-up of being convenient for throw the ball.
An exhaust elbow 11 is also connected above the electric piston cavity 2 corresponding to the ball throwing pipeline and is used for exhausting gas in the pressure detection section between the upper ball valve 20 and the lower ball valve 9, so that the pressure in the pressure detection section returns to zero. In the course of the work, under the non-bowling state, go up ball valve 20 and ball valve 9 closed state down, because pressure release has accomplished, the pressure measurement section should be zero pressure, but ball valve 9 fault leakage back down will lead to becoming the high pressure in the pressure measurement section, at this moment if throw the ball again and will lead to the whole leakages of formation pressure, consequently well storehouse pressure sensor 8 detects pressure and is zero, can carry out the operation of bowling, ball valve 9 gas leakage under explaining when non-zero, report to the police and stop the operation of bowling, wait for the maintenance.
The rotary base 4 is divided into a flat base 4-1 with a horizontal upper surface and an inclined base 4-2 with an inclined upper surface, the ball distributing port 7 is positioned on the flat base 4-1, and the height of the upper surface of the inclined base 4-2 is gradually reduced towards the direction of the ball distributing port 7.
The rotary base 4 is divided into two parts, one part is an inclined base 4-2 with an inclined upper surface, the other part is a flat base 4-1, and the height of the inclined surface of the inclined base 4-2 is gradually reduced towards the direction of the ball distributing port 7 until the height of the inclined surface is consistent with that of the flat base 4-1. As shown in fig. 2, the inclined base 4-2 is highest at the left side and gradually decreases in height towards the ball distributing port 7 at the right side until the inclined base is consistent with the flat base 4-1.
Therefore, after one foam volleyball falls down, other foam volleyballs can move to the ball distributing opening on the flat base 4-1 along the inclined plane, and the utilization efficiency of the foam volleyball is improved.
The inclined base 4-2 is provided with a desiccant tube groove, and a desiccant tube 12 is connected to the desiccant tube groove.
