Description

[0001] Double-acting water pump drive unit [

The present invention relates to a double-action type amphibious pump drive apparatus, and more particularly, to a double-action type amphibious pump drive apparatus having an improved structure for pumping groundwater by the movement of an electromagnet and a permanent magnet.

Generally, as shown in Fig. 1, the amphibious pump pumps the groundwater with suction force from the ground.

In the case of submersible pumps, the groundwater can be pumped at a deeper depth than the amphibious pump. However, as the depth of sampling increases, the capacity and size of the pump must be increased. Since the pump should be installed inside the borehole, , There was a practical limit to increase the capacity and depth of the pump.

In order to pump deeper groundwater from a small borehole, several electric sampling devices of an inertial pump type have been developed. Typical examples are an inertial ball (Korean Patent No. 10-0770051) or an opening and closing unit (Korean Patent No. 10-1124075 The groundwater is collected by up and down movement.

However, there is a problem in that the above-mentioned devices can not insert the iron core in the electromagnet because the groundwater intake pipe is positioned at the center of the pump.

That is, there is a limitation in increasing the strength of the electromagnet, and it does not provide sufficient power to reciprocate the inertial ball or the separating unit so that the groundwater can be pumped.

In addition, since an inertial ball or an opening / closing unit is used, there is a problem that the amount of pumped water is very small.

In order to solve such a problem, 10-2015-0075889 (name: Bupdong electronic pump) was filed.

A first electromagnet disposed on one side of the housing; a second electromagnet disposed on the other side of the housing, the second electromagnet having a polarity different from that of the first electromagnet; And a piston having permanent magnets installed so as to be movable.

And includes a housing 11, a first electromagnet 12, a second electromagnet 12, and a piston 13, as shown in Fig.

The piston 13 having a permanent magnet is moved inside the housing by the first electromagnet 12 and the second electromagnet 12 to discharge the groundwater to the outside.

Although the conventional double acting electromagnetic pump having such a principle has been filed, it is necessary to develop a product having high precision of operation and high product completion.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a double-acting pumping pump driving apparatus capable of improving the precision of a double-acting electromagnetic pump using an electromagnet.

In order to accomplish the above object, a double-action type amphibious pump drive apparatus according to an embodiment of the present invention is driven to pump groundwater, and includes: a tubular pipe member vertically installed below the ground surface; A pair of electromagnets disposed to face each other in a state of being spaced from each other in the tubular member; A flow path forming member disposed between the pair of electromagnets and fixed to the inside of the tubular member to form a flow path allowing fluid to flow in and out; And a piston disposed on the inner side of the flow path forming member and having a first side connected to the piston and another side passing through the flow path forming member and facing the respective electromagnets, A mobile unit including a pair of rods relatively moved; And a plurality of check valves opened and closed in accordance with movement of the mobile unit.

Wherein the flow path forming member includes an inner cylinder portion having an annular flow path formed between an outer cylinder portion fixed to the tube member and the outer cylinder portion and having a space communicating with the flow path on the inner side thereof, And the other side of each of the rods is disposed to face the respective electromagnets through the inner cylinder.

The check valve includes a pair of inlet valves and a pair of outlet valves. The inner tube has a pair of communication holes communicating with the outer tube, Only one of the pair of communication openings, the inlet valves and the outlet valves enables a positive number, and only the other one is opened in accordance with the opposite movement of the piston in the opposite direction, thereby enabling a repetitive positive number .

The rod includes a contact portion formed at a front end facing the electromagnet and made of a material capable of contacting with the electromagnet. When the contact portion moves in a direction in which the contact portion contacts the electromagnet, an elastic force is applied to the contact portion. And an elastic member disposed between the contact portion and the flow path forming member.

According to the embodiment of the present invention, there is an effect that the outer groundwater can be pumped continuously and continuously while the piston moves by the electromagnets.

According to the flow path forming member employed in the embodiment of the present invention, the piston of the mobile unit is guided by penetrating the inner cylinder of the flow path forming member, thereby improving the precision of the pump.

Therefore, according to the flow path forming member employed in the embodiment of the present invention, since the annular flow path is formed between the inner tube portion and the outer tube portion of the flow path forming member, The pumping operation time can be shortened and the pumping capacity can be increased by having the structure in which the groundwater flows into the other flow path first without waiting.

3 to 6, the double-acting type amphibious pump driving apparatus according to an embodiment of the present invention is driven to pump groundwater, and includes a pipe member 100, a pair of electromagnets 200, A flow path forming member 300, a moving unit 400, and a check valve 500.

The pipe member 100 has a tubular shape and is vertically provided below the earth surface. A pair of electromagnets 200, a flow path forming member 300, a moving unit 400, and a check valve are accommodated in the pipe member 100. The tubular member 100 of the present invention can be implemented in a detachable manner, so that it is possible to replace the internal structure.

The pair of electromagnets 200 are arranged to face each other within the tube member 100 in a spaced apart relationship.

The flow path forming member 300 is disposed between the pair of electromagnets 200 and is fixed to the inside of the tube member 100 to form a flow path for allowing fluid to flow in and out.

The movable unit 400 includes a piston 410 disposed on the inner side of the flow path forming member 300 and one end connected to the piston 410 and the other end passing through the flow path forming member 300, 200 and a pair of rods 420 that are moved relative to the flow path forming member 300 by interaction with the electromagnet 200.

In addition, the plurality of check valves 500 serve to open and close the flow path according to the movement of the mobile unit 400.

Therefore, according to the embodiment of the present invention, there is an advantage that the external groundwater can be continuously and pumped continuously while the piston is moved by the electromagnets 200.

4, the flow path forming member 300 employed in an embodiment of the present invention includes an outer cylinder 310 and an inner cylinder 320. As shown in FIG.

The outer tube 310 is fixedly installed inside the tube member 100.

The inner cylinder 320 has an annular passage 301 between itself and the outer cylinder 310 and a space 303 communicating with the passage 301 on the inner side.

According to the passage forming member 300 employed in the embodiment of the present invention, the piston 410 of the moving unit 400 is disposed in the communication space 303 of the inner cylinder 320, and each rod 420 Is disposed to face the electromagnets 200 through the inner cylinder 320 and can move up and down between the communication spaces 303 of the inner cylinder 320. [

Therefore, according to the flow path forming member 300 employed in the embodiment of the present invention, the piston 410 of the moving unit 400 penetrates the inner cylinder portion 320 of the flow path forming member 300, And the accuracy of the pump can be improved.

According to the flow path forming member 300 employed in the embodiment of the present invention, the annular flow path 301 is formed between the inner cylinder portion 320 and the outer cylinder portion 310 of the flow path forming member 300 Accordingly, when the pump 301 is operated in the double-acting mode, the groundwater flows into the other flow path 301 without waiting for the groundwater to flow into the flow path 301, thereby shortening the pumping driving time and increasing the pumping capacity There are advantages.

5 to 7, a check valve 500 employed in an embodiment of the present invention includes a pair of inlet side valves and a pair of outlet side valves, and the inner cylinder portion 320 have a pair of communication holes communicating with the outer tube 310.

In one embodiment of the present invention, it is preferable that the diagonal inlet valve and the outlet valve operate in pairs, as shown in FIG.

Thus, the diagonal inlet valve and outlet valve are opened. At this time, the piston 410 moves upward by the upper electromagnet 200 and the lower electromagnet 200.

At this time, as the piston 410 moves upward, groundwater existing in the upper part of the communication space 303 is discharged to the outside through the upper discharge side valve, and groundwater flows into the other flow passage 301 through the lower inlet side valve And then flows into the communication space 303.

Thereafter, when the electromagnet 200 is reversely operated, the piston 410 moves downward in the inner cylinder 320 as shown in FIG. At the same time, the opposite valve is opened.

Then, groundwater below the inner cylinder 320 is pushed by the piston 410, and groundwater pushed by the piston 410 is discharged to the outside through the other discharge side valve.

At this time, the groundwater flowing through the other inlet-side valve flows into the upper portion of the inner cylinder 320 through the oil passage 301.

In other words, the check valve 500 adopted in the embodiment of the present invention is capable of opening a pair of communication openings, inlet valves, and discharge valves according to the unidirectional movement of the piston 410, And the other one of the pistons 410 is opened in the other direction opposite to the one direction, thereby enabling a repetitive positive number.

8 is a view for explaining another embodiment of the flow path forming member 300 employed in an embodiment of the present invention.

8, the rod 420 includes a contact portion 421 formed at a front end facing the electromagnet 200 and made of a material capable of contacting the electromagnet 200, and the contact portion 421 Further includes an elastic member 600 disposed between the contact portion 421 and the flow path forming member 300 so as to apply an elastic force to the contact portion 421 when the movable member 421 moves in a direction to contact the electromagnet 200 .

As described above, since the elastic member 600 is disposed between the contact portion 421 and the flow path forming member 300, there is an advantage that the driving of the piston 410 can be supplemented.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but is capable of numerous modifications and variations, It is obvious.
