Description

  The present invention relates to a patrol inspection device. More specifically, the inspection device according to the present invention is a device for observing power distribution equipment arranged at high places such as the upper part of the utility pole, so as to reduce the weight of the inspection device and improve the operability. It is a devised one.

  In the distribution line system, a transformer and a switch are provided on the upper part (high position) of the utility pole, and insulators are also used. Many of these power distribution devices (transformers, switches, insulators, etc.) are arranged at high places such as the upper part of the power pole. Since such a power distribution device deteriorates with age, there is a demand for observing the deteriorated state from the outside to grasp the deteriorated state.

If the power distribution device arranged at a high place is observed from the ground, only the vicinity of the bottom surface of the device can be observed, and the state of the side surface and top surface of the device cannot be observed. For this reason, in the conventional inspection, the distribution equipment was inspected from the top of the pillar or using an aerial work vehicle.
Therefore, various inspection inspection devices have been developed that can inspect the entire surface including the upper surface and side surfaces of power distribution equipment from the ground.

  A conventional inspection and inspection device is a device in which a camera is fixedly mounted in advance on the tip of a bag (see, for example, Patent Document 1). In order to use this conventional inspection and inspection device, a person supports the base end side of the kite, raises the tip of the kite upward, and locks the tip of the kite to the overhead wire (distribution line). The tip position is fixedly supported. In this state, the distribution device or the like was photographed with a camera and the appearance of the distribution device or the like was inspected to determine the aged deterioration state.

  By the way, since the distribution equipment used as an inspection object apparatus differs in installation height, in order to carry out an external appearance inspection of all the distribution equipment used as an inspection object in each work site, it is necessary to lengthen the eaves length to about 15 m.

  If the camera is fixedly mounted on the tip of the heel in advance as in the case of the prior art, the heel will be raised when the heel is raised upward or extended upward. The tip of the heel is shaken greatly by bending. If the tip of the heel is shaken greatly in this way, there arises a problem that an operation such as locking the heel to the overhead electric wire becomes extremely difficult. It was also difficult to hold the wrinkles during the examination.

Also, in order to prevent a large wobbling due to the warp of the heel, a thick heel having a strong and high rigidity must be used. However, when such a heavy kite is used, since the kite weight increases, there arises a problem that it becomes difficult to operate.
Furthermore, since the weight that can be operated by the operator is limited, the weight of the camera fixedly mounted on the tip of the heel is limited as the weight of the heel increases, which makes it impossible to mount a high-performance camera. Will also occur. Incidentally, in the prior art, the weight of a camera that can be used is limited to about 900 g. However, if the camera has good performance, the weight is about 2 kg.

  An object of the present invention is to provide a patrol inspection apparatus with good operability that can use an inspection apparatus such as a heavy camera while using a light and long scissors.

The configuration of the patrol inspection device of the present invention that solves the above problems is as follows.
Buttock,
A pedestal portion supporting the base end portion of the collar portion in a state in which the collar portion can rotate about its axis and the collar portion can tilt as a whole with the base end portion as a fulcrum;
An inspection device provided with the collar so as to be able to move along the longitudinal direction of the collar with an inspection device;
An inspection part moving mechanism for moving the inspection part along the longitudinal direction of the flange;
An electric wire locking part that is provided at the tip of the collar part and can be locked to an overhead electric wire;
It is characterized by having.

Moreover, the structure of the patrol inspection device of the present invention is as follows.
An insulating collar that is stretchable along the longitudinal direction;
A pedestal portion supporting the base end portion of the collar portion in a state in which the collar portion can rotate about its axis and the collar portion can tilt as a whole with the base end portion as a fulcrum;
A camera unit provided on the hook part so as to be movable along the longitudinal direction of the hook part, with a camera for inspection.
A pulley provided at a distal end portion of the flange portion, a reel mechanism provided at a proximal end side of the flange portion, and a reel mechanism that is fed out and wound by the reel mechanism and is fed out from the reel and then attached to the pulley. A camera part moving mechanism comprising a wire that is wound and reversed and the tip is connected to the camera part;
An insulative wire locking portion that is provided at the tip of the collar and can be locked to an overhead wire;
It is characterized by having.

Moreover, the structure of the patrol inspection device of the present invention is as follows.
An inclination adjusting screw for adjusting the upper surface of the pedestal portion horizontally with respect to the installation surface is provided on the pedestal portion.

  According to the present invention, the hook portion is extended and the electric wire is locked by the electric wire locking portion provided at the tip of the hook portion, and then the camera portion is moved by the operation of the camera portion moving mechanism using the hook portion as a guide. I try to pull it up to the tip of the buttocks. In this way, by supporting the lower end of the collar part with the pedestal part and supporting the upper end of the collar part with the overhead electric wire, even if the rigidity and strength of the collar part itself are low, the cage supported in such a state is supported. The part became strong as a guide, and the heavy camera part could be lifted.

  And when extending the buttock or leaning the buttock against the electric wire, the camera moving mechanism, which is a heavy object, is positioned below the buttock, so that the shake of the buttock can be suppressed, and the operation It will be easy. Moreover, since the rigidity of the collar part itself may be small, it is possible to reduce the weight of the collar part and thus the weight of the entire apparatus.

  The best mode for carrying out the present invention will be described below in detail based on examples.

  FIG. 1 is a schematic diagram showing a patrol inspection apparatus according to an embodiment of the present invention, and FIGS. 2 and 3 are detailed configuration diagrams thereof.

[Description of inspection inspection device configuration]
First, referring to FIG. 1, a schematic configuration of a patrol inspection apparatus 1 according to an embodiment of the present invention will be described first. The patrol inspection device 1 includes a pedestal unit 10, a collar unit 20, a camera unit (inspection unit) 30, a camera unit movement mechanism (inspection unit movement mechanism) 40, and an electric wire locking unit 50. .
Assembling (connecting) and disassembling (disconnecting) the pedestal part 10, the collar part 20, the camera part 30, the camera part moving mechanism 40, and the wire locking part 50 that constitute the patrol inspection device 1 is simple. You can do it.

  The pedestal portion 10 supports the proximal end portion (lower end portion) of the flange portion 20. In addition, the pedestal 10 supports the base end of the collar 20 so that the collar 20 can rotate about its axis, and the collar 20 can tilt and move as a whole with the base end serving as a fulcrum. And it is tiltably supported).

  In this example, the collar portion 20 has a stretchable collar structure, but it is also possible to use a long collar (total length of about 15 m) that cannot be stretched. The flange 20 is made of an insulating material such as glass fiber (FRP). In FIG. 1, the collar part 20 is in the extended state.

  The camera unit 30 can slide along the collar unit 20. In this example, when the camera unit 30 surrounds the periphery of the collar unit 20, in other words, the camera unit 30 is provided in the collar unit 20 with the collar unit 20 penetrating the center of the camera unit 30. The camera unit 30 can move along the longitudinal direction of the collar unit 20.

  The camera unit moving mechanism 40 is a mechanism for moving the camera unit 30 along the longitudinal direction of the collar unit 20. The camera unit moving mechanism 40 includes an electric reel mechanism 41, a pulley 42, and a wire 43. In this example, the electric reel mechanism 41 is disposed at the lower end portion of the flange portion 20, but may be disposed on the base 10. The pulley 42 is disposed at the distal end portion of the flange portion 20. The wire 43 is fed out and wound from the electric reel mechanism 41, and the wire 43 fed out from the electric reel mechanism 41 is reversed after being wound around the pulley 42, and the tip of the wire 43 is the camera unit 30. It is connected to.

  The wire locking portion 50 is formed of an insulating member having a T shape. In addition, in the present Example, although it is set as the T-shaped electric wire latching | locking part, it is not restricted to this shape.

  Next, with reference to FIG. 2 and FIG. 3 which is a III arrow view of FIG. 2, the detailed structure of the patrol inspection apparatus 1 according to the present embodiment will be described. 2 and 3, the collar portion 20 is in a degenerated state.

  As shown in FIGS. 2 and 3, tilt adjustment screws 12 are provided at the four corners of the base plate 11 of the base portion 10. By rotating the inclination adjusting screw 12, a downward protrusion amount with respect to the base plate 11 changes. For this reason, even if the installation surface is not a horizontal surface, the pedestal surface 11 can be held in a horizontal state by rotating the inclination adjusting screw 12 to adjust the downward protrusion amount.

Further, the tilting shaft 13 of the pedestal portion 10 rotatably supports the base end portion (lower end portion) of the flange portion 20. For this reason, the collar part 20 can be tilted (oscillated) as a whole with the base end part as a fulcrum.
Furthermore, the rotary bearing 14 of the base part 10 supports the base end part (lower end part) of the collar part 20 rotatably. For this reason, the collar part 20 can rotate around the axis.

The flange portion 20 is configured by concentrically arranging a plurality of divided cylindrical tubes having different outer diameter dimensions. To be precise, the shape of each cylindrical tube is a tapered cylindrical tube shape in which the diameter on the upper side of the cylindrical tube is slightly smaller than the diameter on the lower side.
When stretched, the relatively inner cylindrical tube is stretched upward relative to the relatively outer cylindrical tube, the innermost cylindrical tube becomes the distal end side (upper end side), and the outermost cylindrical tube is the proximal end. Side (lower end side). Moreover, the connection between the relatively upper cylindrical tube and the relatively lower cylindrical tube is locked. The upper and lower cylindrical tubes can be locked and unlocked manually by the operator.

  And when an operator draws out each cylindrical tube, the collar part 20 is extended | stretched and the length becomes long. For example, the total length of the ridge is about 15 m. In addition, when the operator pushes back each cylindrical tube in a state where the locks between the cylindrical tubes are released, the collar portion 20 is degenerated and the length thereof is shortened.

  The main body casing 31 of the camera unit 30 is provided in the collar unit 20 so as to surround the periphery of the collar unit 20. That is, the main body casing 31 is provided in the flange section 20 in a state where the flange section 20 penetrates the central portion of the main body casing 31.

The body housing 31 of the camera unit 30 incorporates a holding / moving mechanism 32 that slides the body housing 31 along the longitudinal direction of the flange 20 while holding the peripheral surface of the flange 20 from the outer peripheral side. ing. The holding / moving mechanism 32 includes a plurality of rods 32b each having a roller 32a that slides on the outer peripheral surface of the flange portion 20, a link mechanism 32c, and an urging member (spring or cylinder) 32d. Has been. By the urging force of the urging member 32d, the roller 32a is pressed against the outer peripheral surface of the flange portion 20, whereby the plurality of rods 32b clamp (hold) the flange portion 20. The plurality of rods 32b are arranged on the upper side and three on the lower side, and the upper three rods 32b and the lower three rods 32b are radially centered around the flange portion 20, respectively. Is arranged.
As a result, the camera unit 30 can slide along the longitudinal direction of the collar part 20 while sandwiching the outer peripheral surface of the collar part 20.

The main body casing 31 of the camera unit 30 is provided with an inspection camera (inspection device) 33 for photographing the power distribution device, and a wireless device 34.
An image captured by the camera 33 is transmitted as a wireless signal by the wireless device 34. This wireless signal is received by a receiver (not shown) placed on the ground, and the received image is displayed on a monitor (not shown) placed on the ground.

  In addition, you may make it transmit the image | video image | photographed with the camera 33 to a ground monitor etc. by a wire communication.

  The electric reel mechanism 41 of the camera unit moving mechanism 40 winds and feeds the wire 43. That is, a winding switch (not shown) is attached to the electric reel mechanism 41, and when the winding switch is turned on (ON) by an operator, the electric motor is driven to wind the wire. Further, the electric reel mechanism 41 is attached with a restraint torque adjuster (not shown) for adjusting the restraint torque. When the torque for pulling out the wire 43 becomes larger than the restraining torque set by the restraining torque adjuster, the wire 43 is fed out from the electric reel mechanism 41.

  The wire 43 fed out from the electric reel mechanism 41 is wound around the pulley 42 and reversed, and the tip of the wire is connected to the camera unit 30.

[Description of inspection operation of inspection equipment]
Next, with reference to FIG. 4A to FIG. 4F, an inspection operation by the inspection inspection device 1 having the above-described configuration will be described.

  First, as shown in FIG. 4A, the inspection inspection device 1 is assembled at the inspection target site, or the assembled inspection inspection device 1 is arranged at the inspection target site.

Next, as shown in FIG.4 (b), an operator extends the collar part 20 upwards manually, and makes the front-end | tip of the collar part 20 higher than the height of an overhead electric wire. At this time, the restraint torque set by the restraint torque adjuster of the electric reel mechanism 41 is made small so that the wire 43 is fed out as the collar portion 20 extends, and the camera portion 30 remains in the lower position. To maintain.
As described above, it is important in the operation of the inspection inspection device 1 to keep the camera unit 30 in the lower position even when the collar unit 20 is extended.

Next, as shown in FIG. 4 (c), the extended flange 20 is tilted, and the flange 20 is leaned against the overhead electric wire L.
At this time, since the camera unit 30 which is a heavy object is located at the lower position, the deflection of the flange portion 20 (especially the deflection at the tip portion) is reduced, and the tilting operation of the flange portion 20 can be easily performed. .

The operator moves the pedestal portion 20 to a position directly below the overhead electric wire L, and gradually reduces the length of the heel portion 20 while returning the inclination of the heel portion 20 (returning to the vertical direction). The overhead electric wire L is locked by the electric wire locking portion 50. FIG. 4F shows a state in which the overhead electric wire L is locked by the wire locking portion 50.
Also at this time, since the camera unit 30 which is a heavy object is located at the lower position, the movement of the collar part 20 (especially the vibration at the tip part) is reduced, and the operation of returning the collar part 20 to the vertical direction, The locking operation to the overhead electric wire L by the wire locking portion 50 can be easily performed.

  In the state of FIG. 4D, since the lower end portion of the flange portion 20 is supported by the pedestal 10 and the upper end portion is engaged and supported by the overhead electric wire L, the flange portion 20 is supported at two locations on the upper and lower sides. become. For this reason, even if the collar part 20 itself has small rigidity and is easily bent, when the state shown in FIG. 4D is reached, the deflection of the collar part 20 becomes extremely small and becomes a strong guide member.

Next, even if the restraint torque set by the restraint torque adjuster of the electric reel mechanism 41 is increased and a pulling torque corresponding to the weight of the camera unit 30 acts on the wire 43, the wire 43 is fed out from the electric reel mechanism 41. Do not.
Then, as shown in FIG. 4E, when the winding switch of the electric reel mechanism 41 is turned on (ON), the wire 43 is wound around the electric reel mechanism 41, and accordingly, the camera unit 30 moves the flange portion 20. Is moved upward as a guide member. At this time, since the flange portion 20 is a strong guide member that is supported at the vertical position, the camera portion 30 can be easily lifted (suspended) even if the weight of the camera portion 30 is heavy.
For this reason, as the camera 33 mounted on the camera unit 30, a high-performance heavy camera (for example, a weight of 2 kg) can be used.
The weight of the camera unit 30 or the like is supported by the flange unit 20 and the overhead electric wire L.

In this state, the camera 33 can photograph and check the power distribution device arranged at a high place. That is, it is possible to determine an aged deterioration state or the like by projecting an image sent from the camera 33 on a monitor or the like and visually inspecting the appearance of the power distribution device.
Note that in order to change the shooting direction of the camera 33 (an angle along the circumferential direction of the collar 20), the operator manually rotates the entire collar 20 along the circumferential direction so that the orientation of the camera 30 is changed. As a result, the shooting direction of the camera 33 is changed.

  When the inspection is completed, the restraining torque of the electric reel mechanism 41 is made smaller than the weight of the camera unit 30. Then, due to the weight of the camera unit 30, the wire 43 is drawn out from the electric reel mechanism 41, and the camera unit 30 is lowered along the collar unit 20. When the camera unit 30 is lowered to the lower end position of the collar unit 20 (returns to the state of FIG. 4D), the state returns to the state of FIG. 4C, and then returns to the state of FIG. The unit 20 is degenerated to return to the state of FIG.

  In this way, the inspection inspection device 1 can efficiently perform the appearance inspection of the power distribution equipment at a high place.
