Next, the camera unit 200 is provided with a lens to shoot and monitor the inside of the tank. FIG. 3 is a perspective view of the camera unit 200 of the orientation control apparatus 1000 of FIG. 1, and FIG. 5 is a camera. 6 is a side view of the unit 200, and FIG. 6 is a front view of the camera unit 200. As shown, the camera unit 200 is disposed on the camera body 210, the jig 230 to be disposed above the camera body 210 to support the camera body 210, and the top of the jig 230. And a fixing plate 250 having an opening formed at the center thereof. The camera body 210 is tilted upward or downward with respect to the jig 230, the jig 230 is panned leftward or rightward with respect to the fixing plate 250, and the fixing plate 250 is connected to the camera body 210 and the camera body 210. It is configured to lift in the vertical direction together with the jig 230.

The camera body 210 is not limited in kind as long as it is a camera provided with a photographing lens. In the present exemplary embodiment, left and right sides of the image capturing direction in which the photographing lens of the camera body 210 is disposed are defined as left and right sides of the camera body 210 for convenience of description. In this case, the camera body 210 may include a fixing part 213 to which one end of the tilting wire 310 is connected, a weight 217 having a predetermined load, and may further include a guide groove 215. .

That is, the left panning wire 351 is wound in one direction, for example, in a clockwise direction with respect to the rotating reel 270 with one end fixed to the rotating reel 270, and conversely, the right panning wire 353 is rotated at one end. While being fixed to the reel 270, the reel 270 is wound in the other direction, for example counterclockwise. Thus, when the left panning wire 351 is pulled upward, the left panning wire 351 is released from the rotary reel 270 while the rotary reel 270 rotates clockwise, and the right panning wire 353 is rotated reel. It is wound up at 270. As a result, the jig 230 coupled with the rotary reel 270 is panned in a clockwise direction. On the contrary, when the right panning wire 353 is pulled upward, the right panning wire 353 is released from the rotating reel 270 while the rotating reel 270 rotates counterclockwise, and the left panning wire 351 is rotated. The reel 270 is wound up. As a result, the rotary reel 270 rotates in the counterclockwise direction, and the jig 230 coupled with the rotary reel 270 is panned in the counterclockwise direction.

8A is a perspective view illustrating a winding form of the tilting wire 310 with respect to the roller unit 400, and FIG. 8B is a side view illustrating a winding form of the tilting wire 310 with respect to the roller unit 400. As shown, the tilting wire 310 may be wound on at least two fixing

rollers

411, 412, 413 and one moving roller (tilting system moving roller 451). The tilting system moving roller 451 is set to move relative to the two fixing rollers 410 on which the tilting wire 310 is wound when an operation of the tilting lever 530 is applied, and thus the tilting wire 310 Tow). On the contrary, when the tilting lever 530 operation is released, the tilting system moving roller 451 may return to an initial position by an external force, for example, a load of the camera unit 200 connected to the tilting wire 310. Specifically, in FIG. 8A or 8B, the tilting wire 310 extending from the wire drum 100 is cloud-supported by the first fixing roller 411 to be primarily changed in orientation, and subsequently rolling on the tilting system moving roller 451. After the support is secondarily changed in orientation, the second fixed roller 412 is rolled to support the third alignment. Additionally, the tilting wire 310 may extend outside the case 500 via the third fixing roller 413 and the direction changing roller 415.

The tilting control of the camera body 210 is performed by the interaction of the tilting lever 530, the tilting system moving roller 451, the tilting wire 310, and the camera body 210. In the initial stage when no external force is applied to the tilting wire 310 connected to the camera body 210, the camera body 210 is positioned so that the weight 217 is disposed at the lowermost portion. 217) (eg, downward in FIG. 5). In this case, a portion of the tilting wire 310 is wound around the outer circumferential surface of the camera body 210 along the guide groove 215. Thereafter, when the tilting lever 530 of the case 500 is rotated, the tilting movement roller 451 moves in a direction away from the two fixing

rollers

411 and 412 that support the tilting wire 310. The wire 310 is pulled upward. In the embodiment of FIG. 8B, the tilting wire 310 is pulled when the tilting system moving roller 451 moves to the left. At this time, if the traction force is greater than the gravity due to the load of the weight 217, the tilting wire 310 is pulled upward, and the fixed portion 213 coupled with one end of the tilting wire 310 also gradually rotates. Accordingly, the camera body 210 tilts upward or downward with respect to the jig 230 about the axis, and the imaging direction of the camera lens is adjusted. For example, in FIG. 5, the fixing part 213 coupled to one end of the tilting wire 310 rotates and the camera body 210 tilts downward.

When the tilting lever 530 is rotated in reverse, the tilting system moving roller 451 gradually returns to the initial position, and the fixing part 213 also rotates in the opposite direction due to the restoring force of gravity of the weight 217. Accordingly, the tilting wire 310 is pulled downward, and the camera body 210 is tilted to the initial position. 5, the fixing part 213 coupled to one end of the tilting wire 310 rotates, and the camera body 210 tilts upward. Of course, when no force is applied to the tilting lever 530, the tilting movement roller 451 may naturally return to the initial position by the gravity of the weight 217 or the camera body 210, and thus the tilting wire ( 310 may be towed off.

[Panning Wire 350]

4 is a conceptual diagram illustrating a method in which the panning wire 350 is wound around the rotary reel 270. 9A and 9B show the winding form of the left panning wire 351 for the roller portion 400, and FIGS. 10A and 10B show the winding form of the right panning wire 353 for the roller portion 400. . As shown in FIGS. 9A and 9B, the left panning wire 351 may be wound on at least two fixing

rollers

411, 412, 413 and the left panning wire winding roller 453L of the panning movement roller 453. have. The panning system moving roller 453 is set to move in position with respect to the two fixing

rollers

411 and 412 on which the left panning wire 351 is wound, when an operation of the panning lever 550 is applied, and thus the left panning wire 351 is moved. The panning wire 351 is towed. Specifically, the left panning wire 351 extending from the wire drum 100 is cloud-supported by the first fixing roller 411 to be primarily changed in orientation, and subsequently the left panning wire winding roller of the panning system moving roller 453. After rolling support at 453L and the orientation is changed secondarily, rolling is supported by the second fixing roller 412 and the orientation is changed in third order. In addition, the left panning wire 351 may extend outside the case 500 via the third fixing roller 413 and the turning roller 415.

On the other hand, Figure 10a or 10b shows the winding form of the right-panning wire 353 for the roller portion 400. As shown in FIGS. 10A and 10B, the right panning wire 353 may be wound on at least two fixing

rollers

412, 413, 414 and the right panning wire winding roller 453R of the panning system moving roller 453. have. The panning system moving roller 453 is set to move relative to the two fixed

rollers

413 and 414 on which the right panning wire 353 is wound when an operation of the panning lever 550 is applied. Towing panning wire 353. Specifically, the right panning wire 353 extending from the wire drum 100 is first cloud-supported by the second fixing roller 412 to be firstly changed in orientation, followed by secondly by the third fixing roller 413. Is changed. Thereafter, the right panning wire winding roller 453R of the panning system moving roller 453 is cloud-supported, and the orientation is changed in the third, and is then cloud-supported by the fourth fixing roller 414, thereby changing the orientation in the fourth. In addition, the left panning wire 351 may extend to the outside of the case 500 via the direction changing roller 415.

At this time, as illustrated in FIGS. 9B and 10B, the winding direction of the left panning wire 351 with respect to the left panning wire winding roller 453L is the right panning wire 353 with respect to the right panning wire winding roller 453R. Is the opposite of the winding direction.

Panning of the camera body 210 is performed by the interaction between the panning lever 550, the panning movement roller 453, the left panning wire 351 and the right panning wire 353, and the camera body 210. There are two cases of panning direction, leftward or rightward, so these two cases will be described separately.

First, when the panning lever 550 of the case 500 is rotated (for example, left-turned), the panning movement roller 453 moves in the first direction away from the two fixed rollers supporting the left panning wire 351. The positional movement moves the left panning wire 351 upward. For example, in the embodiment of FIG. 9B, the panning system moving roller 453 is moved to the left direction away from the first and second fixing

rollers

411 and 412, and thus the left panning wire 351 is pulled. At this time, the length is extended downward to correspond to the upward traction of the left panning wire 351. At this time, the direction in which the panning system moving roller 453 moves away from the fixing

rollers

411 and 412 for supporting the left panning wire 351 is closer to the fixing

rollers

413 and 414 for supporting the right panning wire 353. Direction, the right panning wire 353 is released to the contrary to the left panning wire 351. Accordingly, while the left panning wire 351 is released from the rotary reel 270 and the right panning wire 353 is wound around the rotary reel 270, the jig 230 connected to the rotary reel 270 is fixed plate 250. Panning left against.

Subsequently, when the panning lever 550 of the case 500 is rotated in the opposite direction, the panning movement roller 453 moves in the opposite direction, that is, in a direction away from the two fixing rollers supporting the right panning wire 353. The right panning wire 353 is pulled upward. For example, in the embodiment of FIG. 10B, the panning system moving roller 453 is moved in the right direction away from the third and fourth fixing

rollers

413 and 414, and thus the right panning wire 353 is pulled out. At this time, the direction in which the panning system moving roller 453 moves away from the fixing

rollers

413 and 414 supporting the right panning wire 353 is closer to the fixing

rollers

411 and 412 supporting the left panning wire 351. Direction, the left panning wire 351 is released to the contrary to the right panning wire 353. Accordingly, while the right panning wire 353 is released from the rotary reel 270 and the left panning wire 351 is wound around the rotary reel 270, the jig 230 connected to the rotary reel 270 is fixed plate 250. Panning to the right relative to.

[Lifting wire 370]

11A is a perspective view illustrating a winding form of the lifting wire 370 with respect to the roller 400, and FIG. 11B is a side view illustrating a winding form of the lifting wire 370 with respect to the roller 400. As shown, the lifting wire 370 can be wound on at least two fixing

rollers

411, 414, but not on the moving

rollers

451, 453. Specifically, in FIG. 11A or FIG. 11B, the lifting wire 370 extending from the wire drum 100 is cloud-supported by the first fixing roller 411 to change its orientation primarily, and subsequently to the second fixing roller 412. Supported and the orientation is changed secondarily. In addition, the lifting wire 370 may extend outside the case 500 via the turning roller 415.

Lifting operation of the camera body 210 by the orientation control device 1000 of the present invention is made by the interaction of the lifting lever 510, the wire drum 100 and the lifting wire 370. Specifically, the wire drum 100 is rotated by the operation of the lifting lever 510, and the lifting wire 370 is wound around the wire drum 100 by the rotation of the wire drum 100. 370 is pulled upward, and the guide plate 290 and the camera unit 200 connected to the lifting wire 370 vertically move upward.

[Breaking mechanism]

The braking mechanism is achieved by the interaction of the lifting wire 370, the guide plate 290 and the brake cam 700. As described above, in the orientation adjusting device 1000 of the present invention, the guide plate 290 and the camera unit 200 connected to the lifting wire 370 are upwardly supported by the pulling force of the lifting wire 370, If the lifting wire 370 is cut, the guide plate 290 and the camera unit 200 are in danger of falling down the housing 600. Accordingly, the present invention can further install the brake cam 700 on the guide plate 290 for the purpose of stability of the device.

As shown in FIGS. 12 and 13, the brake cam 700 is a plate-shaped device having a special contour, and is pivotally installed at a side end portion of the guide plate 290, such that the guide plate 290 and the housing 600 are provided. Is placed in the space between the inner surface of the. The brake cam 700 is pivotally coupled to the guide plate 290 in a vertical direction, and pivots upward from below the inner surface of the housing 600. At this time, the spring member is interposed between the brake cam 700 and the side end of the guide plate 290, the brake cam 700 is configured to be forced to the inner surface of the housing 600 by the elastic force of the spring member. . However, one end of the brake cam 700 is connected to the lifting wire 370 passing through the guide plate 290 under the guide plate 290, and the brake cam 700 may be pulled out by the tension of the lifting wire 370. One end maintains the state joined below the guide plate 290 against the elastic force of the spring member. In this state, the other end of the brake cam 700 is spaced apart from the inner surface of the housing 600.

At this time, when the tensile force of the lifting wire 370 is extinguished by damage such as cutting of the lifting wire 370, the brake cam 700 pivots toward the inner surface of the housing 600 by the elastic force of the spring member, and thus lifting One end of the brake cam 700 which has been joined to the lower side of the guide plate 290 by the tension force of the wire 370 is released from the lower side of the guide plate 290. Subsequently, the other end of the brake cam 700 abuts on the inner surface of the housing 600 by the pivoting motion, and generates frictional force between the inner surface of the housing 600 and the brake cam 700. A plurality of protrusions and the like may be formed on the other end surface of the brake cam 700 that is in contact with the inner surface of the housing 600 to reinforce the braking force.

With this structure, when the accident occurs that the lifting wire 370 is damaged or worn and cut during use of the orientation adjusting device 1000 of the present invention, the brake cam 700 reflects the inner surface of the housing 600 reflexively. Pivoting toward the inner surface of the housing 600, so that the guide plate 290 coupled to the lifting wire 370 and the camera unit 200 coupled thereto are moved downward of the housing 600. The occurrence of falling accidents can be prevented.

As mentioned above, although embodiment of this invention was described, the person of ordinary skill in the art should add, change, delete, add, etc. the component within the range which does not deviate from the idea of this invention described in the claim. The present invention may be modified and changed in various ways, and it should be understood that the present invention is included in the scope of the present invention.
