Description

  The present invention relates to a separation determination device that determines whether or not an electric wire and various objects including the electric wire are separated from each other by a predetermined distance or more.

  In arranging the service line or the communication line, it is necessary to separate the service line from the communication line by a predetermined distance (for example, 30 cm) or more. This is stipulated in laws and technical standards concerning electrical and communication facilities. For this reason, when installing or inspecting a service line or a communication line, an operator checks whether or not the service line and the communication line are separated from each other by a predetermined distance or more.

  Currently, a method often used as a method for confirming whether or not the service line and the communication line are separated from each other by a predetermined distance or more is visual measurement. In addition to this, the ground height of each of the service line and the communication line and the distance on the same plane between the service line and the communication line are measured, and the distance between the service line and the communication line is calculated by using these measurement results. There is also a way to ask. There is also a method of finding a place where the lead-in line and the communication line are closest to each other, and measuring a distance between the lead-in line and the communication line at the place with a ruler. Further, as shown in Patent Documents 1 and 2 below, there is a method using a measuring instrument.

  However, it is not easy to visually check whether the lead-in line and the communication line are separated from each other by a predetermined distance or more, and accuracy is lacking. That is, since the lead-in line and the communication line are often arranged at a place away from the worker, such as a place high above the worker's head, visual inspection is difficult. In addition, the lead-in line and the communication line are not necessarily parallel to each other, and the extension direction of the lead-in line and the communication line are different from each other, and the two often cross each other three-dimensionally in the air. For this reason, it is difficult to accurately measure whether or not the lead-in line and the communication line are separated from each other by a predetermined distance or more.

  In addition, as described above, the ground height of each of the service line and the communication line and the distance on one plane between the service line and the communication line are measured, and the distance between the service line and the communication line is calculated using these measurement results. The method of obtaining by the above method requires a large number of work points and a lot of time because it requires many calculations and calculations. In addition, as described above, the method of finding the closest point between the lead-in line and the communication line and measuring the distance between the lead-in line and the communication line with the ruler accurately finds the point where the lead-in line and the communication line are closest to each other. Is difficult.

  In addition, the measuring instrument described in Patent Document 1 measures the distance between the high-voltage overhead line and the ground, then measures the distance between the building and the ground, and obtains the difference between the high-voltage overhead line and the building. It measures the separation distance. In the measuring method using this instrument, it is necessary to measure the ground height of two places, that is, the ground height of the high-voltage overhead line and the ground height of the building, which requires a large number of work steps. Moreover, when the lead-in line and the communication line are arranged apart from each other in the horizontal direction, it is difficult to measure the distance between the lead-in line and the communication line using this instrument.

  Moreover, in the measuring instrument described in Patent Document 2, confirmation is easy when the lead-in line and the communication line are arranged in parallel to each other, but the lead-in line and the communication line cross three-dimensionally. In some cases, confirmation is not easy. Also, in order to efficiently perform the confirmation work using this instrument, two workers are required to perform the work of attaching the instrument to the electric wire and the operation of moving the instrument in the direction of laying the electric wire. It becomes a big scale.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a separation determination device according to an embodiment of the present invention together with a service line, a communication line, and an operator. FIG. 2 shows a state in which the separation determination device, the lead-in line, the communication line, and the worker in FIG. 1 are viewed from above. FIG. 3 shows a state in which the rod unit is contracted and the spherical unit is removed from the arm unit in the separation determination device in FIG. FIG. 4 shows the detailed structure of the separation determination apparatus in FIG.

  In FIG. 1, a separation determination device 1 according to an embodiment of the present invention is a device that determines whether or not an electric wire and an object are separated from each other by a predetermined distance or more. In the present embodiment, the lead-in wire 2 is taken as an example of an electric wire, and the communication line 3 is taken as an example of an object. For example, an AC current of 100 V or 200 V flows through the lead-in wire 2. The communication line 3 is a weak electric wire, for example, a telephone line. In the case of such an example, since the lead-in wire 2 and the communication line 3 need to be separated from each other by 30 cm or more, the predetermined distance is 30 cm. Hereinafter, the predetermined distance is referred to as “minimum separation distance”.

  As shown in FIG. 1, the lead-in line 2 and the communication line 3 are located above the worker and away from the worker. For example, the lead-in line 2 and the communication line 3 are at a height of 5 to 6 m from the ground. Further, as shown in FIG. 2, the lead-in line 2 and the communication line 3 have different extension directions, and intersect each other in a three-dimensional manner. Further, the lead-in line 2 is disposed above the communication line 3.

  As shown in FIG. 1, the separation determination device 1 includes a spherical unit 11, a rod portion 12 that supports the spherical unit 11, and connects the spherical unit 11 to the rod portion 12 and positions the spherical unit 11 with respect to the rod portion 12. The arm part 13 to determine and the contact detection part 14 which detects that the spherical unit 11 contacted the lead-in wire 2 are provided.

  The spherical unit 11 includes a sphere 21 and a detection terminal portion 51 that covers the surface of the upper hemisphere of the sphere 21. The sphere 21 is a true sphere, and is formed of a lightweight insulating material such as foamed polystyrene. By making the sphere 21 lightweight, it is possible to facilitate the operation of determining whether or not the lead-in wire 2 and the communication line 3 are separated from each other by a minimum separation distance or the separation determination device 1.

  The diameter of the sphere 21 is set to a value corresponding to the minimum separation distance. For example, the diameter of the sphere 21 is set to a value equal to the minimum separation distance. The diameter of the sphere 21 may be set to a value obtained by subtracting the radius of the lead-in wire 2 and the communication line 3, the thickness of the detection terminal portion 51, the allowable error, and the like from the minimum separation distance. Further, the diameter of the sphere 21 may be set to a value obtained by adding a predetermined adjustment value to the minimum separation distance.

  As shown in FIG. 4, the sphere 21 is attached to the arm portion 13 through the shaft member 22 together with the detection terminal portion 51. That is, a small-diameter shaft insertion hole 21A penetrating along the diameter of the sphere 21 is formed, and the shaft member 22 is inserted into the shaft insertion port 21A so as to be fitted. The shaft member 22 is formed in a cylindrical shape from a lightweight metal material such as aluminum, and female screws are formed at both ends thereof. The detection terminal portion 51 is covered on the upper side of the sphere 21 into which the shaft member 22 is inserted, and the positions of the small-diameter holes 51 </ b> A formed at the two peripheral portions of the detection terminal portion 51 are formed at both ends of the shaft member 22. The male screw 23 is inserted and fastened to one female screw, and the male screw 41 of the arm 13 is inserted and fastened to the other female screw. Thereby, the spherical body 21 is attached to the arm portion 13 together with the detection terminal portion 51.

  Further, as shown in FIG. 3, the spherical unit 11 can be detached from the arm portion 13 and can be separated from the rod portion 12. The spherical unit 11 may be separated by rotating the spherical unit 11 together with the shaft member 22 around the axis of the shaft member 22 and removing the other female screw of the shaft member 22 from the male screw portion 41 of the arm portion 13. For example, when carrying or storing the separation determination device 1, the spherical unit 11 is removed from the arm portion 13. This facilitates transportation and storage. In addition, it is good also as a structure which maintains the state to which the spherical unit 11 and the arm part 13 were connected, and removes the arm part 13 from the rod part 12. FIG.

  As shown in FIG. 1, the rod portion 12 is a long rod-like member, and is configured by connecting a plurality of (for example, three) cylindrical members 31, 32, and 33. Each cylindrical member 31, 32, 33 is formed of a lightweight material having strength such as aluminum or carbon fiber. Moreover, the rod part 12 is formed so that expansion-contraction is possible. The rod portion 12 has a length of, for example, about 1.5 m to 2 m when contracted as shown in FIG. 3, but has a length of, for example, about 4 m to 6 m when extended as shown in FIG. 1. The worker can determine the interval between the lead-in wire 2 and the communication wire 3 at a position away from the worker by extending the rod portion 12. Specifically, the operator can determine the distance between the lead-in wire 2 and the communication line 3 having a ground height of about 5 m to 6 m while standing on the ground. In addition, the operator can easily carry and store the separation determination device 1 by contracting the rod portion 12.

  As the expansion / contraction structure of the rod portion 12, for example, a well-known structure that is employed in a swing bar, a multistage extension tripod, or the like can be used. For example, the cylindrical members 31, 32, and 33 are nested as shown in FIG. 3, and when the rod portion 12 is extended as shown in FIG. 1, the upper end of the cylindrical member 31 and the lower end of the cylindrical member 32 are mutually connected. The upper end of the cylindrical member 32 and the lower end of the cylindrical member 33 are fixed to each other by being fitted or fastened. The cylindrical members 31, 32, and 33 are separated from each other, threaded portions are formed at the upper end of the cylindrical member 31, both ends of the cylindrical member 32, and the lower end of the cylindrical member 33, respectively. It is good also as a structure which connects the cylindrical member 32 and connects the cylindrical member 32 and the cylindrical member 33. FIG.

  As shown in FIG. 4, the arm portion 13 is formed in a rod shape from aluminum, stainless steel, resin, or the like. The lower end side of the arm portion 13 is fixed to the upper end side of the cylindrical member 33 of the rod portion 12. A male screw portion 41 is formed at the upper end portion of the arm portion 13. As described above, the spherical unit 11 is attached to the upper end side of the arm portion 13 by inserting and fastening the female screw of the shaft member 22 inserted into the spherical body 21 into the male screw portion 41.

  Further, the lower end portion of the arm portion 13 is positioned on the axis P of the rod portion 12 in a state of being fixed to the upper end side of the rod portion 12 (cylindrical member 33). On the other hand, the upper end side of the arm portion 13 is curved in a direction away from the axis P of the rod portion 12. As a result, the upper end portion of the arm portion 13 is at a position deviated from the axis P of the rod portion 12. As shown in FIG. 4, the degree of curvature of the arm portion 13 is such that the angle R at which the axis P intersects the straight line Q is, for example, 15 degrees to 75 degrees when the straight line passing through the lower end and the upper end of the arm section 13 is Q. The angle is preferably set to 45 degrees.

  As described above, the contact detection unit 14 detects that the spherical unit 11 has contacted the lead-in wire 2. The contact detection unit 14 includes a detection terminal unit 51 and a notification unit 52. The detection terminal portion 51 is formed in a cup shape from a conductive material, and is attached to the sphere 21 so as to cover, for example, the entire surface of the upper hemisphere portion of the sphere 21 as shown in FIG.

  The notification unit 52 is attached to the cylindrical member 31 of the rod unit 12. The notification unit 52 includes an LED (light emitting diode) 53 as a visual information output unit, a buzzer 54 as an audio information output unit, and a control circuit 55. The LED 53 and the buzzer 54 are electrically connected to the control circuit 55. It is connected. Further, the detection terminal unit 51 is electrically connected to the control circuit 55 via a wiring 56. The wiring 56 is disposed inside the arm portion 13 and the rod portion 12. The arm part 13 and the rod part 12 are made of a conductive material, the detection terminal part 51, the arm part 13 and the rod part 12 are brought into contact with each other, and the rod part 12 and the input terminal of the control circuit 55 are connected via wiring. Thus, the electrical connection between the detection terminal unit 51 and the control circuit 55 may be realized.

  When the detection terminal unit 51 comes into contact with the lead-in wire 2, an electrical signal is input from the detection terminal unit 51 to the control circuit 55, and in response to this, the control circuit 55 causes the LED 53 to blink and the buzzer 54 to output an alarm sound. As the electrical configuration of the contact detection unit 14, an electrical configuration of a voltage detector can be employed. Further, as the electrical configuration of the contact detection unit 14, an electrical configuration of a capacitive touch sensor may be employed. Further, a display device may be provided instead of the LED 53, or a speaker may be provided instead of the buzzer 54.

  The position where the notification unit 52 is attached is preferably a position where an operator who works with the rod unit 12 can easily check the blinking of the LED 53. For example, it is desirable to arrange the notification unit 52 at a position that is approximately the same height as the eyes of an operator who works with the rod portion 12.

  The worker uses the separation determination device 1 to determine, for example, as follows whether the lead-in wire 2 and the communication line 3 are separated from each other by a minimum separation distance or more. First, the operator attaches the spherical unit 11 to the arm portion 13 and extends the rod portion 12. Subsequently, as shown in FIG. 1, the worker stands below a portion where the lead-in wire 2 and the communication wire 3 intersect three-dimensionally, grips the lower end side of the rod portion 12, and connects the spherical unit 11 to the lead-in wire 2. An attempt is made to insert it between the communication line 3. When the spherical unit 11 passes between the lead-in line 2 and the communication line 3 without touching both the lead-in line 2 and the communication line 3, the lead-in line 2 and the communication line 3 are separated from each other by a minimum separation distance or more. Can be determined. On the other hand, when the spherical unit 11 comes into contact with both the service line 2 and the communication line 3 and cannot pass between the service line 2 and the communication line 3, the service line 2 and the communication line 3 are separated from each other by a minimum distance. It can be determined that they are not separated from each other.

  Here, FIG. 5 and FIG. 6 show a mode of work (separation judgment work) in which an operator uses the separation judgment device 1 to judge whether or not the lead-in line 2 and the communication line 3 are separated from each other by a minimum separation distance or more. Show. In the separation determination device 1, it is determined whether or not the lead-in wire 2 and the communication line 3 are separated from each other by a minimum separation distance using a sphere 21 having a diameter corresponding to the minimum separation distance. That is, a part that provides a criterion for determining whether or not the distance is the minimum separation distance is a sphere 21. As a result, as shown in FIG. 5, regardless of the angle at which the spherical unit 11 is inserted between the lead-in line 2 and the communication line 3, the lead-in line 2 and the communication line 3 are separated from each other by a minimum separation distance or more. Whether or not can be accurately determined. Therefore, even if the operator tilts the rod portion 12 to one side as shown in FIG. 5 (1) or to the other side as shown in FIG. 5 (2), the separation determination of the lead-in wire 2 and the communication line 3 is performed. Work can be done. For example, even if there is an obstacle directly below the point where the service line 2 and the communication line 3 intersect three-dimensionally and the worker cannot enter the place, It is possible to check whether or not the spherical unit 11 passes between the lead-in line 2 and the communication line 3 by pointing the spherical unit 11. As described above, according to the separation determination device 1, the workability of the separation determination work can be improved by using the sphere 21 as the portion that provides the determination criterion as to whether or not the distance is the minimum separation distance.

  As shown in FIG. 4, in the separation determination device 1, the angle R between the straight line Q passing through the lower end and the upper end of the arm portion 13 and the axis P of the rod portion 12 is, for example, 45 degrees. (The center of the sphere 21) is determined at a position deviating from the axis P of the rod portion 12. Therefore, as shown by arrows A1 to A4 in FIG. 6, even when the worker stands directly below a place where the lead-in wire 2 and the communication wire 3 intersect three-dimensionally, the spherical unit 11 communicates with the lead-in wire 2. It can be inserted between the lines 3 from various directions to check whether the spherical unit 11 passes between them. Therefore, even when there is an obstacle around the portion where the lead-in wire 2 and the communication line 3 intersect three-dimensionally, the worker can avoid the obstacle and place the spherical unit 11 between the lead-in wire 2 and the communication line 3. The direction in which insertion can be performed is arbitrarily selected, and the separation determination work can be performed. Thereby, the workability | operativity of a separation determination work can be improved.

  Moreover, although the space | interval of the lead-in wire 2 and the communication line 3 is not more than the minimum separation distance, the spherical unit 11 bends the lead-in wire 2 or the communication wire 3 and spreads both, the lead-in wire 2 and the communication wire 3 It is thought that it will pass through between. In such a case, the detection terminal unit 51 contacts the lead-in wire 2, the LED 53 blinks, and an alarm sound is output from the buzzer 54. Thereby, the operator can determine that the lead-in line 2 and the communication line 3 are not separated from each other by a minimum separation distance or more. Thus, according to the separation determination device 1, even when the distance between the lead-in line 2 and the communication line 3 is close to the minimum separation distance, it is possible to determine with high accuracy whether or not both are separated from each other by at least the minimum separation distance. it can.

  In particular, in the separation determination device 1, since the detection terminal portion 51 is provided on the surface of the upper hemisphere portion of the sphere 21, the operator can surely check the contact between the spherical unit 11 and the lead-in wire 2. That is, the lead-in line 2 is disposed above the communication line 3. For this reason, when the worker is standing and working under the place where the lead-in wire 2 and the communication line 3 cross three-dimensionally, the worker can connect the spherical unit 11 between the lead-in wire 2 and the communication wire 3. When inserted in between, the contact between the spherical unit 11 and the lead-in wire 2 cannot be confirmed directly with eyes. This is because the location where the spherical unit 11 and the lead-in wire 2 come into contact with each other is hidden behind the spherical unit 11, and the operator cannot see this location with his eyes. According to the separation determination device 1, when the spherical unit 11 and the lead-in wire 2 come into contact, the detection terminal unit 51 detects this, the LED 53 blinks, and an alarm sound is output from the buzzer 54. The contact between the spherical unit 11 and the lead-in wire 2 can be reliably confirmed by the LED 53 or the buzzer 54. Since the operator can directly confirm the contact between the spherical unit 11 and the communication line 3 with the eyes, if the contact between the spherical unit 11 and the lead-in line 2 can be confirmed with the LED 53 or the buzzer 54, the lead-in line 2 It is possible to reliably determine whether or not the communication lines 3 are separated from each other by at least the minimum separation distance.

  Further, in the separation determination device 1, the detection terminal portion 51 is formed in a cup shape and covers the entire surface of the upper hemisphere portion of the sphere 21 so that the contact between the spherical unit 11 and the lead-in wire 2 can be detected. Is wide. Therefore, as shown in FIG. 5, even when the angle at which the spherical unit 11 is inserted between the lead-in wire 2 and the communication wire 3 is varied, the contact between the lead-in wire 2 and the detection terminal portion 51 can be reliably detected. it can.

  Further, according to the separation determination device 1, when the lead-in wire 2 and the communication line 3 are arranged on the same plane, the spherical unit 11 is inserted between the lead-in wire 2 and the communication line 3 in a spherical shape. By moving the unit 11 in the direction in which the lead-in line 2 and the communication line 3 extend, it is possible to easily find a place where the lead-in line 2 and the communication line 3 are closest to each other, and quickly determine the distance between the two at that point. be able to. Moreover, according to the separation determination device 1, the separation determination work can be easily performed by one worker.

  As described above, according to the separation determination device 1 according to the embodiment of the present invention, it is possible to easily and accurately determine whether or not the lead-in wire 2 and the communication line 3 are separated from each other by at least the minimum separation distance. Furthermore, as described above, the workability and determination accuracy of the separation determination work can be improved.

  In the above-described embodiment, the angle R between the straight line Q passing through the lower end and the upper end of the arm portion 13 and the axis P of the rod portion 12 is set to 45 degrees, for example, so that the spherical shape attached to the upper end of the arm portion 13 Although the case where the position of the unit 11 is determined at a position deviated from the axis P of the rod portion 12 is taken as an example, the present invention is not limited to this. As shown in the arm portion 61 shown in FIG. 7, the degree of bending of the arm portion can be changed, the tip side can be raised and lowered with respect to the lower end side of the arm portion, and the angle R in FIG. 4 is changed. It may be possible. Thereby, the position of the spherical unit 11 with respect to the rod part 12 can be changed according to the electric wire and the object to be subjected to the separation determination work, or the arrangement thereof, and high workability can be realized in various situations. it can. Thus, the arm part 61 which can change the grade of curvature can be implement | achieved using a flexible shaft, for example.

  Moreover, the arm part 13 is not limited to the shape which curves and draws a circular arc as shown in FIG. For example, the arm portion may have a shape in which a substantially middle portion thereof is bent like an arm portion 62 shown in FIG. 8 (1), or the rod portion 12 like an arm portion 63 shown in FIG. 8 (2). It is good also as a shape extended in linear form, inclining with respect to the axis line P from the front-end | tip part of (cylindrical member 33).

  Further, as shown in FIG. 9, the spherical unit 11 may be provided with a rotation mechanism 64 so that the spherical unit 11 can rotate around the shaft member 22. Thereby, the detection terminal part 51 provided in the upper hemisphere part of the spherical unit 11 can be moved to the horizontal side or the lower side by rotating the spherical unit 11. FIG. 9 shows a state where the detection terminal portion 51 has moved downward. Thus, by making the spherical unit 11 rotatable, it is possible to ensure good workability of the separation determination work according to the arrangement of the electric wire and the object.

  Moreover, in the said embodiment, although the case where it was determined by the separation | spacing determination apparatus 1 whether the drawing wire 2 and the communication line 3 were separated from each other more than the minimum separation distance was mentioned as an example, this invention is not limited to this. The separation determination device 1 may determine whether another electric wire and another object are separated from each other by a predetermined distance or more. For example, the separation determination device 1 may determine whether the service line and the building are separated from each other by a predetermined distance or more. In this case, if the minimum separation distance between the lead-in line and the building is defined as, for example, 50 cm, the diameter of the sphere 21 is set to a value corresponding to 50 cm (for example, a value equal to 50 cm). Alternatively, a plurality of spheres 21 having different diameters may be prepared, an appropriate sphere 21 may be selected according to the object of separation determination, and the separation determination operation may be performed by attaching the selected sphere 21 to the arm unit 13.

Further, the present invention can be appropriately changed without departing from the gist or concept of the invention that can be read from the claims and the entire specification, and the separation determination device with such a change is also a technical concept of the present invention. include.
Further, the above embodiment is a separation determination device for determining whether or not the electric wire and the object are separated from each other by a predetermined distance, a sphere having a diameter corresponding to the predetermined distance, and a long rod shape And a rod portion that supports the sphere on the tip side thereof, and is a specific example of the separation determination device, and is provided on a part of the surface of the sphere in the separation determination device. It is also a specific example of the separation determination device characterized by comprising contact detection means for detecting contact with the electric wire.
