The marine CCTV system according to the present invention may include an IP camera (1) that performs an operation according to an image signal, and a cable (2) that is formed at the lower end of the IP camera (1).

Referring to FIG. 1 , an IP camera 1 is a camera that transmits network-based HD images, and refers to a closed circuit television camera that provides HD-class resolution video, and typically displays 1280X720, 1920X1080 or higher high-resolution images at 15 seconds per second. ~30 frames can be provided. Also, like the IP method, the video stream can be encoded in MPEG4/H.264, etc. and exported through the cable (2).

Referring to FIG. 2 , the cable 2 is formed starting on the lower surface of the IP camera 1 and is formed at a 'C'-shaped angle. can be done to prevent damage to

3 to 5, the marine CCTV system is a cable (2) around a body (3), a blocking member (4), a cap (5), a cover (6), a coupling member (7), a cylinder ( 8) and a silicon member 9 may be further included. The cover 6 is formed in a 'ㅁ' shape surrounding the exterior of the cable 2 to protect the cable 2 by external shock or waterproof treatment, and includes a cap 5 and body 3 to be described later. It is possible to block the inflow of moisture or ultraviolet rays irradiated to the blocking member 4 by covering it. The blocking member 4 is provided on the upper surface of the body 3 and may be formed of NBR material. The cap 5 is connected to and fastened to the blocking member 4 and pressurizes the cable 2 at the same time as pressing to block the moisture flowing through the cable 2 . The coupling member 7 is installed on the cable 2 to be coupled to the cylinder 8 , and may include a silicone member 9 on its inner surface. The cylinder (8) is coupled to the coupling member (7) and connected to the end of the cable (2) so that it can be fastened including the silicone member (9) on the cable (2). The silicone member 9 can block the flowing moisture by pressing the cable 2 when the coupling member 7 and the cylinder 8 are coupled.

6 to 11 , in the moisture blocking module according to the present invention, the cable distribution box 500 may include a cable box 400 , a connection part 200 , and an insertion part 300 .

The connection part is a fixed tube 210 for accommodating the connection terminal C connected to the electrode body of the electric wire (L), an insertion tube 220 for movably receiving the fixed tube, and a movable and rotatably accommodating tube for accommodating the insertion tube. It may include a coupling pipe 230 .

The insertion part may include a coupling end 310 coupled to the coupling pipe of the connection part and a fixing ring 320 for fixing the coupling end to the cable distribution box.

The connection terminals are respectively connected to the electrode body of the electric wire, and are engaged with the connection terminal (C') to which the electric wire of the cable box is connected, and are energized. A linker (C1) for fixing is formed to protrude.

The fixed tube has a tubular shape in which a protrusion 211 is formed at one point of the circumferential surface, and the connecting terminal C is accommodated, and a locking protrusion 212 may be formed at an end thereof.

At this time, the connection terminal (C) is movably fixed in the fixing tube (210), the guide groove (213) for penetrating the linker (C1) is formed along the longitudinal direction.

The insertion tube 220 has a hollow tube shape into which the fixed tube 210 is movably inserted, and a guide groove ( 223) is formed, the protruding jaw 222 is formed on the central circumferential surface.

As a result, the guide groove 223 is formed along the longitudinal direction from the insertion end 221 to the protruding jaw 222 , and due to this structure, the projection 211 of the fixing tube 210 is the insertion end of the insertion tube 220 . It can move smoothly along the guide groove 223 in a protruding state within the range of the 221 and the protruding jaw 222 , and through this, the fixed tube 210 is inserted into the insertion tube 220 within the range of the guide groove 223 . ) and is movably fixed.

Referring to FIG. 10 ( a ), since the fixed tube 210 ′ must be movably accommodated in the insertion tube 220 , a certain gap may occur between the circumferential surface of the fixed tube 210 ′ and the inner surface of the insertion tube 220 . Inevitably, through this, the fixed tube 210 ′ and the insertion tube 220 can move relatively easily.

However, since the fixed tube 210 ′ according to the present invention has a unique function of limiting the rotation of the coupling tube 230 , the mobility of the fixed tube 210 ′ and the insertion tube 220 is reduced in order to effectively exhibit the function. should be somewhat limited.

Accordingly, the fixed tube 210 ′ and the insertion tube 220 should have a degree of adhesion that can ensure the minimum fixability to the extent that they do not move under their own weight.

Referring to FIG. 10( b ), the locking jaws 212 are protruded from one end of the fixing tube 210 so that the protruding locking jaws 212 are in close contact with the inner surface of the insertion tube 220 . Of course, in this case, as shown, one end of the fixing tube 210 on which the locking jaw 212 is located is subjected to pressure, and through this, the one end is bent and pressurizes the inner surface of the insertion tube 220 with its own restoring force.

This pressure may be a means for physically fastening the fixed tube 210 and the insertion tube 220 .

For reference, as shown in FIG. 10(b), in the portion where the locking jaw 212 is formed, forming a cutout so that the bending of the one end can be made without interference can prevent the inflow of rainwater and seawater from the sea. can be said to be desirable.

On the other hand, when a strong tension is applied from the outside, it is not possible to ensure a firm coupling of the fixed tube 210 and the insertion tube 220 only by the pressure applied by the locking jaw 212 to the inner surface of the insertion tube 220 .

In order to solve this problem, as shown in FIG. 10(a), when the fixing tube 210' is sufficiently inserted into the insertion tube 220, the locking jaw 212 passes through the insertion tube 220 to the outside. While exposed and caught, it is possible to prevent the fixed tube 210 from being separated from the insertion tube 220 even if it receives a large tension.

The coupling tube 230 is to rotatably and movably accommodate the insertion tube 220, and a coupling rod 231 having a screw thread 232b is provided on the inner surface, and the inner surface of one end of the insertion tube 220 is detached. A stopper 133 for prevention is formed to protrude, and a ratchet gear 234 for fixing the coupling between the connection part 200 and the insertion part 300 is formed on a surface facing the insertion part 300 .

The coupling band 231 has a shape through which the fixing pipe 210 can pass, and a guide groove 232a opened along the longitudinal direction so that the protrusion 211 of the fixing pipe 210 passes is formed.

Here, the screw thread 232b is not naturally formed at the opening point of the guide groove 232a, and the screw thread 311 formed at the coupling end 310 of the insertion part 300 is formed at a position facing the guide groove 232a. Therefore, even if the coupling tube 230 moves in engagement with the coupling end 310 of the insertion part 300 , the threads 232b and 211 do not interfere with each other.

Since the projection 211 of the fixed tube 210 moving along the guide groove 223 of the insertion tube 220 can move along the guide groove 232a of the coupling band 231, its linear movement is smooth, and the projection ( When a part of the 211 is inserted into the guide groove 223 of the protruding jaw 222 of the insertion tube 220 , the protrusion 211 is a combination of the protruding jaw 222 and the coupling tube 230 of the insertion tube 220 . While holding and supporting the stand 231, the insertion tube 220 and the coupling tube 230 are prevented from rotating with each other.

The coupling spring 240 has one end fixed to the coupling tube 230 and the other end fixed to the insertion tube 220 through elasticity so that the coupling tube 230 can rotate around the insertion tube 220 . apply rotational force.

On the other hand, since the coupling tube 230 is movably coupled to the insertion tube 220 , one end, the other end or both ends of the coupling spring 240 are movable with the insertion tube 220 or the coupling tube 230 . may be closely connected.

In the embodiment according to the present invention, the coupling spring 240 is a coil-shaped spring, and a groove is formed on the circumferential surface of the insertion tube 220 to which the coupling spring 240 is in contact, so that one end of the coupling spring 240 is It is fixed to the insertion tube 220 , and the other end is fixed to the inner surface of the coupling tube 230 .

Before the fixing tube 210, the insertion tube 220, and the coupling tube 230 are combined with the insertion part 300 in an assembled state, the coupling spring 240 must have its own elastic force.

To this end, during the assembly process of the fixed tube 210 , the insertion tube 220 , and the coupling tube 230 , the coupling spring 240 should be installed while maintaining the elastic force.

To this end, in the embodiment according to the present invention, a support protrusion 232c is formed on the outer surface of the coupling band 231, and the support protrusion 232c is formed on the inner surface of the coupling pipe 230 in which the coupling band 231 is inserted. to form an engaging groove 134 to be engaged with.

At this time, the support protrusion 232c is formed to protrude only a portion of the outer surface of the coupling bar 231 , so that the operator rotates the coupling bar 231 arbitrarily during assembly unless the coupling bar 231 is completely inserted into the coupling tube 230 . can do it

As a result, the fixed tube 210, the insertion tube 220, and the coupling tube 230 except for the coupling band 231 are coupled to each other, and in a state in which the coupling spring 240 is released (the state without elastic force), both ends are the insertion tube. When the 220 and the coupling pipe 230 are fixed to each other, the guide groove 232a of the coupling band 231 is aligned with the protrusion 211 and a part of the coupling band 231 is inserted into the coupling pipe 230 . When forcibly rotated, the insertion tube 220 is rotated by the protrusion 211 receiving the rotational force of the coupling band 231, and through this, the coupling spring 240 is twisted and has elastic force.

When sufficient elastic force is ensured, the operator inserts the coupling rod 231 into the coupling tube 230 so that the support protrusion 232c is inserted into the groove, and through this, the insertion tube by the elastic force possessed by the coupling spring 240 . Prevents 220 from rotating.

The insertion part 300 is installed in the cable housing 400, is provided to be electrically and physically connected to the connection part 200, and a connection terminal (C') engaged with the connection terminal (C) of the connection part 200 is provided. It may include a fixing ring 320 for fixing the received coupling end 310 and the coupling end 310 to the cable housing 400 .

And a certain insertion groove 312 is formed between the inner surface of the coupling end 310 and the outer surface of the connecting terminal (C').

On the other hand, the insertion part 300 according to the present invention is to forcibly move the fixed tube 210 of the connecting portion 200, and the pressure bar 313 for smoothly facing the protrusion 211 of the fixed tube 210 is the front surface. is formed in

The coupling end 310 of the insertion unit 300 is inserted through the insertion tube 220 as mentioned above and has a guide groove 232a on the outer surface to engage with the screw thread 232b formed on the inner surface of the coupling bar 231 . A screw thread 311 is formed in the forming range of . Therefore, the screw thread 311 of the coupling end 310 is limitedly formed before the entire projection 211 of the fixing tube 210 is inserted into the guide groove 223 of the protruding jaw 222 part, the screw thread 232b of the coupling band 231. ) and do not engage.

The fixing ring 320 fixes the coupling end 310 to the cable housing 400, and when the coupling between the connection part 200 and the insertion part 300 is made, the hook 322 is coupled to prevent the coupling from being released. A plurality of surfaces are formed on the surface facing the ratchet gear 234 of the tube 230 .

The stopper 322 is installed in the groove 325 formed in the body 321 of the fixing ring 320 so as to protrude and rotate forward through the rotation shaft 324, and move forward by the elasticity of the elastic body 323. protrusion supported.

The description of the operation of the ratchet gear 234 and the stopper 322 will be described in detail while describing the binding process of the connection part 200 and the insertion part 300 .

Referring to FIG. 11 , the connection part 200 according to the present invention is mounted in the hollow of the coupling pipe 230 after the fixing tube 210 accommodating the connection terminal C is inserted and fixed into the insertion tube 220 . .

At this time, the protrusion 211 of the fixed tube 210 is formed to pass through the guide groove 223 of the insertion end 221 portion, so that the fixed tube 210 can move along the longitudinal direction of the insertion tube 220 but rotate. It is bound so that it cannot be done.

On the other hand, the projection 211 of the fixing tube 210 is inserted into the guide groove 232a of the coupling rod 231 and engaged, so that the fixing tube 210 and the coupling tube 230 can move with each other in the longitudinal direction, but not rotate. bound so as not to be

The coupling spring 240 for connecting the insertion tube 220 is installed so that its elasticity is maintained in a state in which the fixed tube 210 and the insertion tube 220 and the coupling tube 230 are coupled as shown.

The operator fits the connection terminal (C) located on the connection part (200) to the connection terminal (C') located on the insertion part (300) and inserts the connection part (200) into the insertion part (300).

At this time, the operator holds the coupling tube 230 of the connection part 200 and forcibly inserts the connection part 200 into the insertion part 300 .

If the insertion is continued, the connection terminal (C) of the connection part 200 is closely fitted to the connection terminal (C') of the insertion part 300 and is in close contact, and as shown, the tip of the coupling end 310 is coupled Inserted into the inside of the base 231, the fixed tube 210 engaged with the coupling bar 231 moves along the insertion tube 220 due to the pressure of the tip of the coupling end 310.

Here, since the projection 211 of the fixed tube 210 moves along the guide groove 223 of the insertion tube 220 and is continuously caught and fixed with the protrusion 222, the fixed tube 210 maintains linear movement without rotation. And, due to the pressure by the operator, the connection terminal (C) of the connection part 200 is further inserted into the connection terminal (C') of the insertion part 300 to be in close contact.

This structure prevents the coupling pipe 230 from rotating due to the elastic force of the coupling spring 240 even if the operator releases the hand holding the coupling pipe 230 .

In addition, the insertion end 221 of the insertion tube 220 is inserted into the hollow insertion groove 312 of the coupling end 310 , the pressure bar 210 for efficient contact with the projection 211 is provided at the insertion end 221 . ) to prevent the insertion tube 220 from rotating with respect to the fixed tube 210 while being inserted through the guide groove 223 formed in the .

On the other hand, the screw thread 311 of the coupling end 310 corresponding to the screw thread 232b of the coupling band 231 is a surface or guide groove ( 231a) is formed only on the surface facing, so that the screw threads (132b, 211) do not interfere when moving between the coupling bar (231) and the coupling end (310).

As the operator continues the insertion, when the projection 211 of the fixing tube 210 is completely separated from the guide groove 231a of the coupling bar 231 as shown, the physical between the coupling pipe 230 and the fixing pipe 210 The binding is released, and when the operator releases the hand holding the coupling pipe 230 , the coupling pipe 230 rotates as shown by the elastic force of the coupling spring 240 .

At this time, the coupling pipe 230 moves along the coupling end 310 while the screw thread 232b of the coupling band 231 and the screw thread 311 of the coupling end 310 are coupled, and eventually the coupling pipe 230 is formed. The connection part 200 and the insertion part 300 are automatically physically coupled as a medium.

When the coupling pipe 230 continues to move along the coupling end 310 , the ratchet gear 234 formed on one surface of the coupling pipe 230 comes into contact with the stopper 322 located at the front of the fixing ring 320 .

When the coupling pipe 230 continues to be connected to the coupling end 310 due to the elasticity of the coupling spring 240 , the stopper 322 is in contact with the ratchet gear 234 formed in the coupling pipe 230 . move backwards

That is, the stopper 322 does not interfere with the movement of the coupling pipe 230 when the coupling pipe 230 proceeds in a direction to be coupled with the coupling end 310 .

When the coupling pipe 230 continues to move to the coupling end 310 and the coupling pipe 230 and the fixing ring 320 come into contact with each other and can no longer move, the ratchet gear 234 formed in the coupling pipe 230 and The stoppers 322 formed on the fixing ring 320 are engaged with each other.

When the stopper 322 is engaged with the ratchet gear 234 , it cannot move in the opposite direction to the coupling direction of the coupling pipe 230 .

In order to more reliably engage the stopper 322 and the ratchet gear 234 , a plurality of the hangers 322 are formed on one surface of the fixing ring 320 facing the ratchet gear 234 .

As in the above operation, the release of the coupling between the connection part 200 and the insertion part 300 is prevented by the elastic force of the coupling spring 240, so that the binding between the connection part 200 and the insertion part 300 is more stably ensured. It has an excellent effect in preventing the inflow of rainwater from manatees or seawater from waves.

12 to 19 , in the present invention, a wind power module may be included. The wind power module has a housing 10 installed on the ground, a generator 11 installed inside the housing 10, and a rotating shaft 12 provided in the generator 11 so that one end is exposed to the outer side of the housing 10 . and a wind power module 100 coupled to the rotating shaft 12 .

The wind power module 100 is coupled to the rotating shaft 12 and rotated with the rotating shaft 12 , the case 110 , the main wing 120 provided on the outer surface of the case 110 , and each main wing 120 rotates. and a subwing 130 that is possibly coupled thereto.

The fluid passage 121 of the main wing 120 is opened and closed through the sub wing 130 rotated by the force of wind, and for this purpose, the sub wing 130 is fixed to the upper side of the fluid passage 121 and is coupled to it. Ribs 123 are formed to protrude.

In addition, the main wing 120 is formed to have a curve to transmit more wind force.

The sub wing 130 for opening and closing the plurality of fluid passages 121 of the main wing 120 is a fluid passage according to the direction of the wind blowing into the case 110 when the case 110 is rotated by the wind. (121) is fixed to only one surface of the main wing 120 so as to open and close only in one direction.

To this end, the main wing 120 is formed to be larger than the width of the fluid passage 121 , and is rotatably coupled to the coupling rib 123 of the main wing 120 through a fixing pin 133 .

In addition, auxiliary ribs 131 are protruded from the front surface of the sub wing 130 so that a greater force is transmitted to the sub wing 130 when the wind blows.

Meanwhile, the wind power module 100 may freely change the size and shape of the main wing 120 according to the size of the windmill coupled to the rotation shaft 12 .

Induction horizontal plate 124 is provided at the upper end and lower end of the main wing 120 so that the wind power module 100 can obtain a greater rotational force by the wind, respectively.

The induction horizontal plate 124 is formed in a circular shape, and prevents the wind flowing into the main wing 120 from being discharged to the upper and lower sides of the main wing 120 so that the wind power module 100 obtains greater rotational force. .

In addition, since the main wing 120 is supported by the induction horizontal plate 124, the main wing 120 is prevented from being damaged by the wind.

In addition, a plurality of induction vertical plates 123 are further attached to the outer surface of the induction horizontal plate 124 at regular intervals in the circumferential direction so that the wind can more effectively flow into the main wing 120 side.

And, when installing only the induction vertical plate 123 in the wind power module 100, it is preferable to install the induction vertical plate 123 to be spaced apart from the fixed blades by a predetermined distance to be fixed to one surface of the IP camera.

This is to reduce the weight of the wind power module 100 by installing the induction vertical plate 123 on the outside of the wind power module 100, and to fix the induction vertical plate 123 more stably.

The wind power module 100 according to the first embodiment of the present invention configured as described above, the front of the main wing 120 installed along the circumferential direction of the wind power module 100 is located in the wind direction, In the main wing 120 , a greater force is transmitted to the wind by the sub wing 130 .

That is, since the sub wing 130 has a large fluid passage 121 of the main wing 120 and is installed on the front side of the main wing 120 , rotation by the wind is prevented.

At this time, the main wing 120 with the rear surface of the wind power module 100 positioned in the wind direction is rotated by the force of the wind, and the wind passes through the fluid passage 121 as the sub-wing 130 rotates. resistance will decrease.

As a result, the sub-wing 130 of the main wing 120 opens and closes the fluid passage 121 of the main wing 120 while rotating by the force of the wind according to the direction in which the wind blows. The rotational force is further increased. That is, in the wind power module 100, the main wing 120 provided on one side according to the direction in which the wind blows, the greater the wind force is transmitted by the sub wing 130, and the main wing 120 provided on the other side is blown by the wind. As the sub wing 130 rotates, the wind is discharged through the fluid passage 121, so that the resistance of the wind is reduced, so that the rotational force of the wind power module 100 is further increased.

Referring to FIG. 18 , the wind power module 100 includes the sub wing 130 installed in the main wing 120 so that the sub wing 130 is rotated more easily by the wind to open and close the fluid passage 121 . ) further comprises an auxiliary rotation member 140 for elastically supporting the opening direction in the fluid passage (121).

In addition, a driving body 150 is installed inside the wind power module 100 to restrict rotation or rotation of the auxiliary rotation member 140 .

The auxiliary rotation member 140 is coupled to the hinge 141 of the sub wing 130 and rotates together with the hinge 141, the hinge plate 142, the support plate 143 attached to the case 110, the support plate ( It may include an elastic body 145 provided between the bolt 144 and the hinge plate 142 so that the bolt 144 and the hinge plate 142 movably fastened to the bolt 144 are elastically supported toward the bolt 144. there is.

The hinge 141 is coupled to the center of the hinge plate 142 to rotate together with the sub wing 130 when the hinge plate 142 is rotated, and is coupled to each of the sub wings 130 .

The hinges 141 coupled to each sub-wing 130 are connected in the form of a universal joint so as to be simultaneously operated according to the rotation of the hinge plate 142 .

The hinge plate 142 is formed in a circular shape, and a rotating shaft 151 connected to the driving body 150 is coupled to one side thereof to communicate with the driving body 150 .

One end of the rotation shaft 151 is located inside the case 110 and is connected to the driving body 150 .

A support plate 143 bonded to the case 110 is installed on one side of the hinge plate 142 to elastically support the hinge plate 142 .

A bolt 144 is fastened to the support plate 143 to adjust the elasticity of the elastic body 145 , and the bolt 144 moves through rotation on the support plate 143 to tension or compress the elastic body 145 .

One side of the elastic body 145 is coupled to the hinge plate 142 and the other side is connected to the bolt 144 to elastically support the hinge plate 142 toward the front side of the main wing 120, and tension and compressed

It is preferable to use a tension spring as the elastic body 145 according to the present embodiment.

Since the wind power module 100 receives a certain elasticity toward the front side of the main wing 120 by the auxiliary rotation member 140 , the sub wing 130 , when the wind blows from the rear surface of the main wing 120 , the sub wing As the 130 is rotated more easily, the fluid passage 121 is opened.

Also, referring to FIG. 19 , by adjusting the elasticity of the elastic body 145 using the bolt 144 , rotation of the sub wing 130 may be adjusted according to the strength of the wind.

If the wind is weak, rotate the bolt 144 to tension the elastic body 145 so that the tensile force of the elastic body 145 acts on the sub wing 130 so that the sub wing 130 is easily opened even in a weak wind. do.

And when the wind blows strongly, the sub wing 130 rotates only when the bolt 144 is rotated to compress the elastic body 145 so that the tensile force of the elastic body 145 acts on the sub wing 130 to be small and receives a greater force. will be.

Furthermore, when a strong wind blows enough to fear damage to the main wing 120 due to deterioration of marine weather such as typhoons or tsunamis, the bolt 144 is rotated to minimize the force of the wind transmitted to the main wing 120 to minimize the elastic body 145 ) is stretched to the maximum, the sub wing 130 is rotated in the main wing 120 to open the fluid passage 121 .

At this time, even when the wind power module 100 is rotated, the sub wing 130 is supported by the elastic body 145 to prevent the fluid passage 121 from being sealed, so that the force of the wind transmitted to the main wing 120 is reduced. The wind power module 100 is prevented from being damaged.

Meanwhile, the wind power module 100 opens and closes the fluid passage 121 more easily and conveniently while the sub wing 130 is forcibly rotated by the driving body 150 .

The driving body 150 is installed inside the case 110 and rotates the sub wing 130 so that the sub wing 130 rotates according to the wind direction.

At this time, the driving body 150 operates the sub-wing 130 while rotating together with the wind power module 100 .

Specifically, the driving body 150 includes a hinge plate 142 fixed to the hinge 141, a rotation shaft 151 coupled to the hinge plate 142, a linkage 152 for moving and constraining the rotation shaft 151, It may include a cylinder 160 provided inside the case 110 to operate the linkage 152 .

The rotating shaft 151 is provided on one side of the hinge plate 142 , and is installed through the case 110 so that one end is positioned inside the case 110 .

The rotating shaft 151 is connected to an interlocking body 152 at one end of which is installed movably up and down inside the case 110 .

The linkage body 152 is formed in a cylindrical shape, is coupled to the rotation shaft 12 to move up and down, and long holes 152a into which each rotation shaft 151 is inserted are formed on the outer surface.

The insertion of the rotary shaft 151 into the long hole 152a of the linkage 152 is caused by the rotation of the main wing 120 when the linkage 152 does not restrict the movement of the rotary shaft 151. This is to prevent being caught in the linkage body 152 when it is rotated together.

That is, the linkage 152 may selectively constrain or release the operation of the rotation shaft 151 by the long hole 152a.

For example, if it is located in the center of the long hole 152a of the rotation shaft 151, even if it is rotated by the sub wing 130, its operation is not constrained by the linkage 152 and is freely operated in the long hole 152a.

However, when the rotary shaft 151 comes into contact with the inner surface of the long hole 152a while the linkage 152 is moved upward, the operation is restricted, and if the linkage 152 is further moved in this state, the linkage 152 As the rotation shaft 151 is moved by the , the hinge plate 142 is rotated, and accordingly, the sub wing 130 is rotated.

That is, the sub-wing 130 may be rotated regardless of the wind direction by using the linkage 152 , and the sub-wing 130 may be rotated more effectively according to the wind direction.

The linkage 152 may be installed by freely adjusting the number of the actuators 150 according to the number of the main wings 120 .

Cylinders 160 and 155 for moving the linkage body 152 up and down are mounted on the support plate 111 provided on the inner surface of the case 110 , while the cylinder 160 rod is positioned below the linkage body 152 . bound to the outside.

If the effect of one embodiment on the wind power module 100 of the present invention is described in detail, since the environment in which the IP camera is installed is the sea, a situation accompanied by strong waves and wind power is frequently experienced. Therefore, in order to use such wind energy, the IP camera may be provided with a wind power module. When the wind direction of the sea is consistently blown, the main wing, fluid passage and sub wing of the wind power module operate and rotate to operate the generator of the wind power module. At this time, by providing the induction vertical plate and the induction horizontal plate to the wind power module, it can bring about the effect of concentrating offshore wind energy density, so that there is a cohesive force that can operate the generator compared to the wind energy on the ground. In addition, there is an advantage in that the wind energy that is lost can be minimized by preventing the Bernoulli effect acting on the wind power module due to the vertical movement of the cylinder 160 .
