Description

An anti-wobble structure for driving stability of the submersible pump

The present invention relates to a fixed support structure for driving stability of a submersible pump, and more particularly, a submersible pump installed inside a column pipe to transport a fluid is firmly fixed to the inside of a column pipe, and is configured to facilitate maintenance after installation It relates to a fixed support structure for the driving stability of the submersible pump.

In general, a submersible pump is installed inside a large-diameter column pipe installed to pump up the fluid stored in a water storage tank or water collection tank to the ground or outside, or to supply it to another fluid transfer pipe.

As is known, the submersible pump includes an impeller for suctioning and discharging fluid by centrifugal force by high-speed rotation, a motor for rotatingly driving the impeller, a housing for sealing the motor, and a power supply for supplying power to the motor It consists of a configuration including a cable and a sensor cable for monitoring the operating state of the motor.

In general, a large-diameter column pipe is installed to transport the fluid stored in the water storage tank or water collection tank in a large capacity, and a large-capacity submersible pump is installed near the lower end of the column pipe filled with the fluid inside, that is, near the bottom surface of the water storage tank or water collecting tank. By actuation, the fluid stored in the water storage tank or the water collecting tank is supplied to the ground, the outside, or another fluid transfer pipe through the column pipe.

Most of the submersible pumps are installed in the center of the column pipe installed in an upright position so that the fluid can be discharged to the upper part so that the fluid can be smoothly discharged from the inside of the column pipe.

On the other hand, the submersible pump installed at the inner center of the large-diameter column pipe is also very large in volume to have a large-capacity fluid discharge ability, and thus is composed of a heavy body. It is difficult to accurately install the submersible pump in the inner center of the column pipe later, but it is most important to install the submersible pump stably so that the submersible pump does not flow due to vibrations generated during operation of the submersible pump after installing the submersible pump inside the column pipe.

In order to solve all these problems, the 'submersible pump with support' of Patent Registration No. 10-1107509 (registration date: 2012.01.12) has been devised.

In the case of the above patent, a plurality of deploying members deployed toward the inner circumferential surface of the column pipe at the upper end of the casing of the submersible pump, and a support provided with a screw rod for moving the deploying member in the axial direction are radially arranged to operate the column pipe during operation of the submersible pump. It was designed to prevent the vibration or vibration of the submersible pump from being generated by the deployment member in contact with the inner circumferential surface.

In addition, a driving unit including a main gear, a bevel gear, and a subordinate bevel gear is provided to rotate the screw rod by power to drive the deployment member so that the deployment member is easily deployed, so that the submersible pump is stable inside the column pipe It is configured to operate with the posture maintained.

However, the 'submersible pump with support' of the above-mentioned patent has a disadvantage in that it is difficult to install it in submersible pumps of various capacities (sizes).

That is, the submersible pump is manufactured in various sizes (external) depending on the purpose of use, installation area, discharge amount, inner diameter of column pipe, etc. Also, there was the inconvenience of having to separately manufacture and install each submersible pump according to the specifications or size.

In addition, since the length of the screw rod and the unfolding member must be made to have almost the same or similar lengths, the amount of rotation of the screw rod is inevitably large when the unfolding member is expanded and contracted. It takes time, and there is an inconvenience in the operability of the handle for rotating the main gear when the driving unit is operated for the operation of the deployment member.

That is, as described above, since the submersible pump is installed at the inner lower end of a column pipe of a certain length that is installed upright on the bottom surface of the water storage tank or water collecting tank, the submersible pump provided at the inner lower end of the column pipe from the upper end of the column pipe. There was a disadvantage in that it is very inconvenient to turn the handle while applying a constant rotational force to the handle of the driving unit of the pump.

In addition, since the submersible pump is in close contact with the inner circumferential surface of the column pipe by the deploying member, sufficient supporting force can be secured during initial operation. There was a risk of additional noise and vibration occurring as the gear coupling of the driving part was loosened or released by direct transmission, and the screw coupling force between the screw rod and the deployment member connected to the driven bevel gear side was also loosened.

In addition, a power cable necessary for driving the motor and a sensor cable for monitoring the operating state of the motor are connected to the upper part of the casing of the submersible pump, and are drawn out to the upper part of the column pipe. It is provided radially with respect to the center and has a structure in which the screw rod is coupled in the transverse direction to the rod coupling part. There was a problem that the assembly workability of the submersible pump was inconvenient because it had to be inconvenient.

Therefore, the present applicant improves the assembly workability of the submersible pump and the installation convenience for easy installation inside the column pipe by improving the problems of the above-mentioned patent, and the rotational vibration of the motor or the fluid during long-term use after installation inside the column pipe The present invention was devised by recognizing the necessity of developing a fixed support structure for a submersible pump that can improve the durability of the submersible pump and increase the efficiency of maintenance of the submersible pump by damping the vibration generated by the impact of the submersible pump.

In addition, vertical supports 10 and 12 are installed on both sides of the upper end of the submersible pump P to which the fixed support structure 100 is to be installed, and the mounting bracket 20 is coupled to the inner surface of the vertical supports 10 and 12 . In this state, the base member 30 is seated on the upper surface of the mounting table 20 and the fastening bolts are coupled to the fastening holes provided at both ends of the base member 30, thereby fixing the support structure on the top of the submersible pump (P). (100) is assembled.

Of course, since it is necessary to set the height of the fixed support structure 100 according to another configuration on the upper side of the submersible pump (P), after fixing the vertical supports (10, 12) to both upper sides of the submersible pump (P), the vertical After grasping the coupling position of the mounting base 20 installed on the inner surface of the supports 10 and 12, the mounting base 20 is fixed to the vertical supports 10 and 12, and the variable driving unit is attached to the fixed mounting base 20. (60) and the variable support member (60) and the lower support member (40) are coupled to the base member (30) can be assembled.

In addition, as shown in the installation state diagrams shown in FIGS. 7 and 8 in the process of seating the base member 30 on the mounting table 20, the power supply cable 110 or the sensor connected to the upper end of the submersible pump (P). When the variable support member 50 arranged in all directions is caught according to the position where the cable 112 is drawn out, the support fixing piece 41 of the lower support member 40 is fitted to the fastening bolt 34 of the base member 30 . Since the fastening hole 45 formed in the circumferential direction is long and rectangular, the lower support member 40 is rotated within the penetration length of the fastening hole 45 so that the upper variable support member 50 is not in contact with the cable. It can be adjusted so as not to be fixed to the base member 30 .

Of course, if the dimensions of the submersible pump are different and the left and right widths of the vertical support coupled to the upper end of the submersible pump are varied, the position of the mounting bracket fastening hole of the base member fitted to the vertical fixing bolt 22 of the mounting table should be varied, In the case of the present invention, since the seat fastening hole 32 is formed in a long rectangular shape in the radial direction of the submersible pump, even if the left and right widths of the vertical support are changed within a certain displacement, there is no problem in coupling the base member. It is also possible to assemble a fixed support structure to the submersible pump.

7 shows a state in which the submersible pump (P) to which the fixed support structure 100 shown in FIG. 6 is assembled is installed inside the column pipe (C).

In general, the submersible pump (P), as shown in the drawing, has an upper end motor (M) and an impeller (I) portion at its lower end installed in the vertical direction from the inside of the column pipe (C) in the lower end. It is configured to discharge the fluid in an upward direction.

7, when the submersible pump (P) is positioned at the inner lower end of the column pipe (C), the power supply cable 110 and the sensor cable 112 connected to the upper end of the submersible pump (P) are connected to the column. It is drawn out through the upper end of the pipe (C), and rotates in one direction by inserting the long rod-shaped rotation operation mechanism 90 into the rotation operation rod 66 protruding upward from the center of the fixed support structure 100 . As the variable support member 50 deployed in all directions extends in the radial direction of the submersible pump, the contact plate provided at the tip of the second variable support is in close contact with the inner surface of the column pipe (C) to firmly fix the submersible pump (P). will support

On the other hand, after positioning the submersible pump (P) inside the column pipe (C) to extend or contract the variable support member (50) located at the lower inner side of the column pipe (C) from the outside of the column pipe (C) In order to rotate the rotation operation rod 66, it is necessary to use a rod-shaped rotation operation mechanism 90 having a predetermined length, but it is rather difficult to insert the rotation operation mechanism 90 into the rotation operation rod 66.

Therefore, in the present invention, as shown in FIG. 8, the fitting guide member 80 in the shape of a hollow pipe slightly larger than the outer diameter of the rotary operation rod 66 is installed on the outer periphery of the rotation operation rod 66, and the column When it is drawn out of the pipe (C), if the operator inserts and lowers the rotation operation mechanism 90 into the inside of the fitting guide member 80, if necessary, the rotation operation mechanism 90 on the rotation operation rod 66 can be easily combined, so that the expansion and contraction operation of the variable support member 50 can be made easily, thereby making it easy to fix, disassemble, maintain and repair the submersible pump.

Of course, it is natural that the rotation operation mechanism 90 is made of a prismatic hollow pipe according to the outer shape of the rotation operation rod 66 .

In the above, the embodiment of the present invention has been described in detail with reference to one embodiment shown in the accompanying drawings, but those skilled in the art may implement various modified embodiments through simple design changes within the scope of the technical spirit of the present invention.
