Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

Example 1:

a novel automatic ware that drains for putting pipe drilling is taken out to picture 1-3 shows, including box 10 and apron 16, the appearance of box 10 is cylindric, and apron 16 is circular, and apron 16 passes through bolted connection at the top of box 10, and three supporting legs 11 of bottom welding of box 10. The bottom of the box body 10 is connected with a first outlet pipe 12 and a second outlet pipe 13, a water discharging automatic valve 121 is installed in the first outlet pipe 12, and a manual ball valve 131 is installed in the second outlet pipe 13; the cover plate 16 is connected with an air inlet pipe, and an air inlet automatic valve 171 is arranged in the air inlet pipe; the middle part of the box body 10 is fixed with a filter screen 15 at the part right below the air inlet automatic valve 171, a filter residue cleaning port 14 is arranged at the position corresponding to the filter screen 15 on the box body 10, and a blind plate 141 is connected to the filter residue cleaning port 14 through a bolt.

The earth particles entering the interior of the box body 10 are filtered by the filter screen 15, silt flows downwards along with water, and the arrangement of the filter residue cleaning port 14 facilitates cleaning of the earth particles on the filter screen 15.

In order to further facilitate the cleaning of the filter screen 15, as shown in fig. 1 and fig. 3, the outer shape of the filter screen 15 is a "shovel-shaped disc", a fixing plate 151 is fixed at the left end of the filter screen 15, the fixing plate 151 is in threaded connection with the filter residue cleaning port 14 through a movable screw 152, a fixing screw 155 is fixed at the inner top of the filter residue cleaning port 14, a pulley 154 is fixed on a part above the filter residue cleaning port 14 on the left inner side wall of the box body 10, a rope 153 is fixed at the upper right end of the filter screen 15, the other end of the rope 153 passes through the pulley 154 and then is bound on the fixing screw 155, in order to facilitate the sliding of the rope 153, and the top of the filter residue cleaning port 14 is chamfered at the connection with the box body 10.

In the process of installing the filter screen 15, firstly, the left end of the filter screen 15 is limited by the movable screw 152, and in order to improve the load bearing capacity of the filter screen 15, the other end of the rope 153 passes through the pulley 154 and then is bound on the fixing screw 155, so that the stability of the filter screen 15 is improved; after soil particles on the filter screen 15 are fully piled, the fixing plate 151 is pressed by hand, the movable screw 152 is unscrewed, the rope 153 is untied, the filter screen 15 can be horizontally moved out of the box body 10 leftwards through the fixing plate 151, the soil particles on the filter screen 15 are poured out, and then the filter screen 15 is installed again.

The liquid level monitoring mechanism is arranged inside the box body 10, as shown in fig. 1-2, the liquid level monitoring mechanism comprises a floating ball 21, a screw rod 20 arranged in the vertical direction is coaxially fixed inside the box body 10, the floating ball 21 is sleeved on the screw rod 20, an internal thread matched with an external thread on the screw rod 20 is arranged on the floating ball 21, the internal thread and the external thread are not self-locked, and a stirring paddle 22 arranged in the horizontal direction is fixed on the outer side wall of the floating ball 21.

As shown in fig. 1, a first switch 23 is installed in the center of the bottom of the tank 10, a contact of the first switch 23 is vertically arranged upward, a second switch 24 is installed on the screw rod 20 below the filter screen 15, a contact of the second switch 24 is vertically arranged downward, the first switch 23 and the second switch 24 can be pressed in the process of up-and-down floating of the floating ball 21, and both the first switch 23 and the second switch 24 are electrically connected with the automatic intake valve 171 and the automatic drain valve 121 through the same controller.

When the automatic water discharge valve 121 is in a normally closed state, water and silt flow to the bottom of the tank 10 and cannot flow out of the water discharger immediately, the liquid level in the tank 10 rises to make the floating ball 21 rise, and when the floating ball 21 rises to press the second switch 24 to be aligned, the second switch 24 controls the automatic water discharge valve 121 to be opened and the automatic air inlet valve 171 to be closed through the controller, so that the tank 10 discharges water and gas is prevented from entering the tank 10; as the tank 10 is discharged, the liquid level in the tank 10 drops, the float 21 drops, and when the float 21 drops to press the first switch 23, the first switch 23 controls the discharge automatic valve 121 to be closed and the intake automatic valve 171 to be opened by the controller.

Meanwhile, in the process that the floating ball 21 floats upwards under the buoyancy of water, the internal thread and the external thread are matched to drive the floating ball 21 to rotate slowly and positively, and the floating ball 21 drives the stirring paddle 22 to rotate slowly and positively; in-process of drainage, along with the decline rapidly of liquid level, floater 21 is the downstream fast under self gravity, and the quick antiport of interior external screw thread cooperation drive floater 21, floater 21 drive stirring rake 22 is the antiport fast, and stirring rake 22 stirs the inside silt of box 10 and the mixture of water, discharges silt as much as possible, avoids silt to condense in the bottom of case and the needs manual work that leads to clear up the silt that condenses bottom box 10. The principle of rotation of the paddles 22 is similar to that of a rotating mop.

The above process is repeated continuously. The gas is pumped out by the gas pump through the gas pipe at the upper end of the automatic water discharger regardless of whether the automatic water discharge valve 121 is opened or closed, and cannot enter the tank 10, thereby preventing the gas from leaking.

In special cases manual draining of the interior of the tank 10 can be achieved by manually opening the ball valve 131.

The above description is only the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention, therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
