Description
Technical Field
The invention relates to a portable negative pressure automatic water drainage device suitable for coal mining operation.
Background
In coal mining, a large amount of gas contained in a coal seam needs to be drained, and in the gas drainage process, water in the coal seam and condensed water of mixed gas easily form accumulated water in a gas drainage pipeline, so that the pipeline is blocked, the gas drainage effect is influenced, and drainage interruption can be caused when the accumulated water is serious. The existing negative pressure automatic water drainage device has the defects of complex structure, large volume, inconvenient installation and carrying and the like.
Disclosure of Invention
The invention aims to provide a portable negative pressure automatic water discharger which has the advantages of simple structure, small volume, light weight and convenient installation and carrying.
The technical scheme of the invention is completed in the following way, and is characterized in that: it is including a vertical water container, upwards install a inlet tube from the container at the top cap center of container, bottom upwards installs an blast pipe on the center axis in the inlet tube, install a magnet on the blast pipe end opening, a float is installed to the lower half in the container, it has a guide bar to erect downthehole slidable mounting in the center of float, the lower extreme of guide bar inserts in the drain hole of container bottom, a lower magnet with last magnet matched with is installed on the top of guide bar, install a sealed pad on magnet down, one side at container top inlet tube is equipped with an intake valve, install the other branch pole that the root can insert in the intake valve at the top of guide bar, install a negative pressure door respectively at the bottom outlet of container and the end of inlet tube. A valve cover is mounted on top of the inlet valve. The container is formed by sealing and butting an upper part and a lower part into a whole.
The invention has the advantages of simple and reasonable structure, small volume, light weight and convenient installation and carrying.

Fig. 1 is a schematic structural view of the present invention.
Detailed Description
The embodiment is described in detail with reference to the accompanying drawings, and comprises a vertical water container 1, a water inlet pipe 2 is arranged at the center of a top cover of the container from the inside of the container upwards, an exhaust pipe 3 is arranged upwards at the bottom of the central axis in the water inlet pipe, an upper magnet 6-1 is arranged on the bottom opening of the exhaust pipe, a floater 9 is arranged at the lower half part in the container, a guide rod 8 is arranged in a central vertical hole of the floater in a sliding way, the lower end of the guide rod is inserted into a drainage port at the bottom of the container, a lower magnet 6-2 matched with the upper magnet is arranged at the top end of the guide rod, a sealing gasket 7 is arranged on the lower magnet, an inlet valve 5 is arranged on one side of the water inlet pipe on the top of the container, a side support rod 11 which can be inserted into the air inlet door is arranged at the top of the guide rod, and a negative pressure door 10 is respectively arranged at the bottom of the container, the water outlet and the tail end of the water inlet pipe. A valve cover 4 is mounted on the intake valve. The container is formed by sealing and butting an upper part and a lower part into a whole.
The water container is formed by injection molding of hard plastic, the floater is arranged at the lower part of the guide rod, when the floater in the container does not rise, the two magnets cannot be attracted, the exhaust pipe is communicated with the water inlet pipe in the container, the door cannot be completely closed even under the action of negative pressure, at the moment, the internal pressure of the container is in a balanced state, and water in the gas drainage pipeline flows into the container through the tail end outlet of the water inlet pipe under the action of self gravity. The negative pressure door at the lower part of the water inlet pipe and the container is in a closed state under the action of negative pressure. Along with the rising of the water level, the floater moves upwards along the guide rod, when the floater rises to the lower part of the side branch pipe, the floater pushes the side branch pipe to move upwards together, so that the two magnets are instantly attracted together to play a sealing role under the action of the sealing gasket, at the moment, the exhaust pipe and the container are sealed, the negative pressure pressing door on the outlet at the tail end of the water inlet pipe is attracted, the water inlet pipeline is sealed, the side branch rod on one side of the guide rod upwards pushes the air inlet valve, the external air enters the container, the negative pressure in the container is destroyed and changed into positive pressure, the negative pressure pressing door on the lower part of the container is opened under the gravity action of the water to start water drainage, when the water level drops to a certain position, the floater sinks to drive the guide rod to move downwards, the two magnets are separated, the sealing gasket is separated from the upper magnet, the exhaust pipe is communicated with the water inlet pipe, the container is in a, the water enters the container again, and the water is circulated in a reciprocating way, so that the aim of periodically and automatically discharging the water is fulfilled, and the water-saving water dispenser has the advantages of simple and compact structure, small volume, light weight, convenience in carrying and good use performance.
