DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In describing the present embodiment, the same designations and the same reference numerals are used for the same components, and further description thereof will be omitted.

1 is a view showing a structure of a tubular electricity generating device 100 according to a first embodiment of the present invention.

1, a tubular electric power generating apparatus 100 according to a first embodiment of the present invention includes a rotary tube 110, a power generation unit 130, and a Tesla unit 140. In this embodiment, the flange 120 is provided at both ends of the rotary pipe 110.

The rotary pipe 110 is connected between piping 50, which is constructed so as to allow the fluid to flow, and a hollow 111 through which the fluid flowing through the pipe 50 flows, as shown in FIG. 2, .

At this time, in the rotary pipe 110, a first blade 112 having an inclined shape is formed around the inner circumferential surface. Accordingly, the fluid flowing into the hollow 111 collides with the first blade 112, and the rotating tube 120 rotates about the center axis by the pressing force generated at this time.

However, this is only one embodiment, and the shape of the first blade 112 can be used in any form as long as it can rotate the rotary tube 120 by pressurizing the fluid.

A magnetic force may be applied to the rotary pipe 110 so that an induction electromotive force may be generated through the power generation unit 130. At this time, the rotary pipe 110 may be formed of a permanent magnet and a magnetic force may be added, or a magnet may be formed of an electromagnet.

In the case of this embodiment, as described in the Korean Patent No. 10-1387155 mentioned in the technical section of the background of the present invention, in the rotary pipe 110, a plurality of permanent magnets are arranged so that the N pole and the S pole are alternately contacted along the outer periphery As shown in FIG.

The power generation unit 130 is provided around the rotary tube 110 and generates an induced electromotive force according to the rotation of the rotary tube 110. In the present embodiment, the power generation unit 130 has a shape including a support 132 and a coil 134.

More specifically, the support rods 132 are spaced apart from each other, and a plurality of the coils 134 are provided between the pair of supports 132 along the outer circumferential surface of the rotary tube 110.

That is, in this embodiment, the induction electromotive force is generated in the power generation unit 130, particularly, the coil 134 according to the rotation of the rotary pipe 110. The principle that electricity is generated between the rotary pipe 110 and the power generation unit 130 is a conventional technique such as a power generation using a rotor and a stator, so that a detailed description thereof will be omitted.

3, the connection structure between the flange portion 120 and the rotary pipe 110 and the pre-installed pipe 50 is shown.

As shown in FIG. 3, the flange portion 120 is provided around both ends of the rotary pipe 110 to rotatably support the rotary pipe 110. The pipe 50 is inserted into the inside of the rotary pipe 110 so that the hollow 51 of the pipe 50 communicates with the hollow 111 of the rotary pipe 111.

The flange portion 120 is in surface contact with the flange 52 of the pipe 50. Although not shown, the flange portion 120 can be fastened to each other by bolt connection or the like.

A bearing module 125 is installed between the flange part 120 and the rotary pipe 110 and between the pipe 50 and the rotary pipe 110. In this case, . At this time, the bearing module 125 may assist the smooth rotation of the rotary pipe 110 and also perform the sealing function of the fluid flowing in the pipe 50.

4 to 6, a view of the Tesla unit 140 is shown.

4 to 6, in the present embodiment, the Tesla unit 140 includes a housing 141, a rotating rim 142, a second blade 144, branch flow paths 150 and 152, .

The branched flow paths 150 and 152 are components for branching a part of the fluid flowing in the pipe 50 and have a shape including an inflow pipe 150 and a discharge pipe 152 in the present embodiment.

1, the inflow pipe 150 is connected to the pipe 50 to branch a part of the fluid before passing through the first blade 112 to flow toward the housing 141 side, Is connected to a pipe (50) through which the fluid passing through the first blade (112) flows to discharge the fluid from the housing (141).

In this embodiment, the discharge pipe 152 is connected to the pipe 50 so that the branched fluid is flowed back into the pipe 50. However, the discharge pipe 152 is not limited to the pipe, And may be discharged to the outside.

The rotation rim 142 is received in the housing 141 and is rotatable so as to surround the circumference of the rotary tube 110. Accordingly, the rotating rim 142 can be rotated by the flow of the fluid introduced into the housing 141.

A plurality of second blades 144 are provided around the rotating rim 142 and the second blades 144 rotate the rotating rim 142 as the fluid hits the rotating rim 142, (142) rotates the rotary pipe (110).

At this time, the angle formed with respect to the flow direction of the fluid may be larger than the angle formed by the first blade 112 with respect to the flow direction of the fluid.

Particularly, in the present embodiment, the second blade 144 is formed in a direction perpendicular to the flow of the fluid flowing into the branched passages 150 and 152, and is curved in the opposite direction, So that the maximum rotational force can be obtained.

As described above, according to the tubular electric power generating apparatus of the present invention, since the Tesla unit 140 further raises the rotation speed of the rotary pipe 110, the amount of electric power generated compared to the case of rotating the rotary pipe with only the first blade 112 Can be increased.

The first embodiment of the present invention has been described above. As described above, since the Tesla unit 140 is provided in the present invention, it is possible to maximize the amount of generated electricity as compared with the conventional tubular power generation apparatus.

On the other hand, in the case of the first blade 112 provided in the rotary pipe 110 (see FIG. 2), the thrust is generated by the linear momentum. Since thrust generation can not recover the kinetic energy and angular momentum, the thrust generation process can not be 100% efficient due to the energy conservation law. Hereinafter, this will be referred to.

2, the uppermost portion of the rotary tube 110 is referred to as a first region, the tip portion of the first blade 112 is referred to as a second region, the rear portion of the first blade 112 is referred to as a third region, ) Is the fourth region, the Bernoulli equation applied to the first region to the fourth region is as follows.

(p: pressure, ρ: air density, v: air velocity, g: gravitational acceleration, z:

The inlet flow rate in the first region and the flow rate in the fourth region are equal to each other in the actual flow as a whole. And, when there is no height difference between the first and fourth regions, the position energy is zero, so gz ₁ and gz ₄ in the above equation can be canceled.

Here, the Bernoulli equation is applied to the second region and the first region as follows.

The Bernoulli equation is applied to the third and fourth regions as follows.

Therefore, the thrust acting on the first blade 112 is given by the following equation.

(F _T : thrust, A: cross-sectional area of pipe, m: mass flow rate)

From the momentum equation using the relative velocity

(u: speed of the area)

If we put the two relational expressions about F _T as equations,

And can be summarized as follows.

As a result, as the pressure decreases from the first region to the second region, the speed is increased, and the pressure is rapidly increased while passing through the first blade 112, thereby lowering the speed. Eventually, half of the total pressure difference between the second and third regions occurs in the second region and the other half occurs in the third region and is canceled.

Due to the progress of the process, the flow in the interior is maintained in a steady state.

Hereinafter, other embodiments of the present invention will be described.

That is, in the case of the present embodiment, the tubular power generation apparatus includes a first Tesla unit 140a and a second Tesla unit 140b, which are provided on both sides of the power generation unit 130, respectively. These structures are the same as those of the first embodiment, and thus a detailed description thereof will be omitted.

In this embodiment, the branch flow paths 150, 151, and 152 are formed to sequentially pass the Tesla units 140a and 140b. Specifically, the branch passages 150, 151, and 152 include an inlet pipe 150, a discharge pipe 152, and a connection pipe 151. The connection pipe 151 connects the first Tesla unit 140a, And the second Tesla unit 140b are connected to communicate with each other.

The fluid branched and flowed from the upstream pipe 50 sequentially passes through the first Tesla unit 140a and the second Tesla unit 140b and can be rejoined to the downstream pipe 50 .

8 is a view illustrating a tubular electricity generating apparatus according to a third embodiment of the present invention.

In the case of the third embodiment of the present invention shown in Fig. 8, all components are formed in the same manner as the above-mentioned second embodiment. In particular, a plurality of Tesla units 140a and 140b are included, including a first Tesla unit 140a and a second Tesla unit 140b.

However, this embodiment is different from the second embodiment in that the branched flow paths 150a, 150b, 152a, and 152b are formed in a plurality of paths so that the Tesla units 140a and 140b pass independently.

Specifically, in the present embodiment, the branched passages 150a, 150b, 152a and 152b include a first inlet pipe 150a, a first outlet pipe 152a, a second inlet pipe 150b, and a second outlet pipe 152b do.

The first inlet pipe 150a and the first outlet pipe 152a are connected to the first Tesla unit 140a and the second inlet pipe 150b and the second outlet pipe 152b are connected to the second Tesla unit 140a. (140b).

That is, in this embodiment, since the plurality of Tesla units 140a and 140b are provided independently of each other to form a separately formed flow path of the fluid, there is an advantage that the power generation amount can be secured without loss of the flow velocity.

FIG. 9 is a view showing a state in which the present invention is applied to a sewage end treatment plant, as an example to which the tubular electricity generating device 100 according to the embodiments of the present invention is applied.

As shown in FIG. 9, the tubular electricity generating device 100 according to the present invention is installed between piping that flows from the sewage storage tank 200 to the purifying structure 250 side. It has the advantage of being able to do.

As described above, it can be seen that the tubular electric power generation apparatus of the present invention can be applied to various facilities. That is, the present invention can be applied to any facility provided that the piping is installed and the fluid can be transferred.
