Description

Technical Field

[0001] The utility model relates to the technical field of measuring the creepage distance of an insulator, in particular to an insulator measuring pen. Background Art

[0002] Disc insulators are a type of insulator commonly used in power lines. Their creepage distance refers to the shortest distance between the surfaces of the insulators. This distance should be greater than or equal to the electrical clearance required by the working voltage and insulation level of the electrical equipment.

[0003] At present, when measuring the creepage distance of a disc insulator, a paper is first manually pasted on the insulator, and then the length of the paper is measured after the paper is removed. This measurement method is inefficient. Utility Model Content

[0004] In order to solve the disadvantage of low efficiency of the existing insulator creepage distance measurement method, the utility model provides an insulator measuring pen which can quickly measure the creepage distance.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An insulator measuring pen comprises a shell, an angle encoder is arranged in the shell, a rotating shaft of the angle encoder is coaxially and detachably connected with a measuring shaft, a through hole is arranged on one side of the shell, an end of the measuring shaft away from the angle encoder extends to the outside of the shell through the through hole and is sleeved with a rubber ring that can roll along the surface of the insulator, the outer diameter of the rubber ring is less than 10 mm, a controller that can calculate the creepage distance according to the angle data of the angle encoder is arranged in the shell, and the controller is connected to a display device that can display the creepage distance.

[0007] Through the above arrangement, the rubber ring is not easy to slip on the insulator; when measuring the creepage distance, there is no need to stick a sticker on the surface of the insulator. After the rubber ring rolls along the surface of the insulator, the user can intuitively obtain the creepage distance of the insulator through the display device; the outer diameter of the rubber ring is small, so that the rubber ring can smoothly enter and exit the narrow groove on the surface of the insulator along the surface of the insulator, thereby increasing the measurement accuracy.

[0008] Furthermore, a shaft sleeve is provided on the measuring shaft, one end of which is detachably connected to the housing, and a rubber bag is provided on the outer side of the shaft sleeve for easy gripping.

[0009] Through the above arrangement, the shaft sleeve increases the stability of the shaft; and the rubber coating increases the comfort of the user's grip.

[0010] Furthermore, a limiting annular groove adapted to the inner side of the rubber ring is arranged at one end of the measuring shaft away from the angle encoder, and the rubber ring is sleeved on the limiting annular groove.

[0011] Through the above arrangement, the contact area between the rubber ring and the measuring shaft can be increased to prevent slipping between the rubber ring and the measuring shaft, thereby improving the measurement accuracy; the limiting annular groove can also prevent the rubber ring from moving axially along the measuring shaft.

[0012] Furthermore, three rubber rings are arranged in sequence along the axial direction of the measuring shaft, and the rubber rings are in contact with each other.

[0013] Through the above arrangement, after increasing the number of rubber rings, it is possible to prevent the rubber rings from being separated from the surface of the insulator during measurement.

[0014] Furthermore, the display device is configured as a smart watch, the controller is integrated with a Bluetooth transceiver, the controller is connected to the smart watch via the Bluetooth transceiver, and the smart watch can receive data from the controller and display the measured creepage distance.

[0015] Furthermore, the measuring shaft includes a first shaft section, a second shaft section, and a connector that can pass through the through hole, which are arranged in sequence from the rubber ring to the angle encoder. The rubber ring is arranged at one end of the first shaft section away from the second shaft section. A slot is arranged on the rotating shaft of the angle encoder, and the connector is inserted into the slot. The outer diameter of the first shaft section is smaller than the outer diameter of the second shaft section, so that an annular boss is formed between the first shaft section and the second shaft section. A first rotating groove that is adapted to the first shaft section and a second rotating groove that is adapted to the second shaft section are arranged in the shaft sleeve. The first rotating groove transitions to the second rotating groove through an annular limiting surface. The first shaft section is rotatably connected in the first rotating groove, and the second shaft section is rotatably connected in the second rotating groove, and the annular boss is in contact with the annular limiting surface.

[0016] The above arrangement makes it easy to disassemble and assemble the measuring shaft so as to replace or repair the measuring shaft.

[0017] Furthermore, the shell includes an upper shell with an opening on one side, and a lower shell detachably connected to the opening, a through hole is arranged on the lower shell, and the shaft sleeve and the lower shell are detachably connected.

[0018] Furthermore, an end of the shaft sleeve close to the shell is vertically fixedly connected with an ear plate, and the ear plate is locked on the shell by a fastener. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0026] See also Figures 1 to 6 An insulator measuring pen comprises a shell 2, an angle encoder 4 is arranged in the shell 2, a measuring shaft 3 is coaxially and detachably connected to the rotating shaft of the angle encoder 4, a through hole 5 is arranged on one side of the shell 2, an end of the measuring shaft 3 away from the angle encoder 4 extends to the outside of the shell 2 through the through hole 5 and is sleeved with a rubber ring 6 that can roll along the surface of the insulator, the outer diameter of the rubber ring 6 is less than 10 mm, a controller 7 that can calculate the creepage distance according to the angle data of the angle encoder 4 is arranged in the shell 2, and the controller 7 is connected to a display device (not shown in the figure) that can display the creepage distance.

[0027] Through the above arrangement, the rubber ring 6 is not easy to slip on the insulator; when measuring the creepage distance, there is no need to stick a sticker on the surface of the insulator. After the rubber ring 6 rolls along the surface of the insulator, the user can intuitively obtain the creepage distance of the insulator through the display device; the outer diameter of the rubber ring 6 is small, so that the rubber ring 6 can smoothly enter and exit the narrow groove on the surface of the insulator along the surface of the insulator, thereby increasing the measurement accuracy. In addition, the insulator measuring pen is small in size, and is basically the size of a pen, which can be put into a pocket and is easy to carry.

[0028] Specifically, the angle encoder 4 can be purchased from the market and installed in the housing 2, which can protect the angle encoder 4; the controller 7 can adopt the existing PLC controller 7; in the present application, the outer diameter of the rubber ring 6 is 8 mm; when measuring, the housing 2 can be held to make the rubber ring 6 contact with one end of the insulator, so that the rubber ring 6 rolls along the surface of the insulator to the other end of the insulator. When the rubber ring 6 rolls, the rubber ring 6 drives the rotating shaft of the angle encoder 4 to rotate through the measuring shaft 3, and the angle encoder 4 can feed back the angle of rotation of the rubber ring 6 to the controller 7. The controller 7 automatically converts the distance rolled by the rubber ring 6 on the surface of the insulator according to the angle of rotation of the rubber ring 6 and the outer diameter of the rubber ring 6, that is, the creepage distance; the display device displays the creepage distance, and the user quickly knows the creepage distance of the insulator through the display device.

[0029] As an implementation method, a sleeve 8 is provided on the measuring shaft 3, one end of the sleeve 8 is detachably connected to the housing 2, and a rubber bag 9 for easy gripping is provided on the outer side of the sleeve 8.

[0030] Through the above arrangement, the shaft sleeve 8 increases the stability of the shaft; and the rubber coating 9 increases the comfort of the user's grip.

[0031] In the present application, the sleeve 8 can support the measuring shaft 3, and the measuring shaft 3 is not easy to shake left and right when rotating, thereby improving the measurement accuracy; the rubber package 9 can make the user hold the measuring pen more closely to the palm, thereby increasing the comfort of holding.

[0032] As an implementation method, a limiting annular groove 10 adapted to the inner side of the rubber ring 6 is provided at one end of the measuring shaft 3 away from the angle encoder 4 , and the rubber ring 6 is sleeved on the limiting annular groove 10 .

[0033] Through the above arrangement, the contact area between the rubber ring 6 and the measuring shaft 3 can be increased to prevent slipping between the rubber ring 6 and the measuring shaft 3, thereby improving the measurement accuracy; the limiting annular groove 10 can also prevent the rubber ring 6 from moving axially along the measuring shaft 3.

[0034] As an implementation mode, three rubber rings 6 are sequentially arranged along the axial direction of the measuring shaft 3 , and the rubber rings 6 are in contact with each other.

[0035] Through the above arrangement, after increasing the number of rubber rings 6, it is possible to prevent the rubber rings 6 from being separated from the surface of the insulator during measurement.

[0036] As an implementation method, the display device is set as a smart watch, and the controller 7 is integrated with a Bluetooth transceiver. The controller 7 is connected to the smart watch via the Bluetooth transceiver. The smart watch can receive data from the controller 7 and display the measured creepage distance.

[0037] In the present application, the smart watch can refer to the existing smart watch, which has Bluetooth function and a touch-sensitive LCD display; the controller 7 sends data to the smart watch in real time through the Bluetooth transceiver, and the smart watch displays the creepage distance through the LCD display for user convenience.

[0038] As an implementation method, the measuring shaft 3 includes a first shaft segment 31, a second shaft segment 32, and a connector 33 that can pass through the through hole 5, which are arranged in sequence from the rubber ring 6 to the angle encoder 4. The rubber ring 6 is set on the end of the first shaft segment 31 away from the second shaft segment 32. A slot 11 is set on the rotating shaft of the angle encoder 4, and the connector 33 is inserted into the slot 11. The outer diameter of the first shaft segment 31 is smaller than the outer diameter of the second shaft segment 32, so that an annular boss 34 is formed between the first shaft segment 31 and the second shaft segment 32. A first rotating groove 12 adapted to the first shaft segment 31 and a second rotating groove 13 adapted to the second shaft segment 32 are set in the shaft sleeve 8. The first rotating groove 12 transitions to the second rotating groove 13 through an annular limiting surface 14. The first shaft segment 31 is rotatably connected in the first rotating groove 12, and the second shaft segment 32 is rotatably connected in the second rotating groove 13, and the annular boss 34 is in contact with the annular limiting surface 14.

[0039] The above arrangement facilitates disassembly and assembly of the measuring shaft 3 so as to facilitate replacement or repair of the measuring shaft 3 .

[0040] In the present application, the measuring shaft 3 is an integrally formed structure; the cross-section of the connector 33 is basically D-shaped, the slot 11 and the connector 33 are adapted, and when the connector 33 is inserted into the slot 11, the connector 33 can drive the rotating shaft to rotate synchronously; when the annular boss 34 and the annular limiting surface 14 are in contact, the annular limiting surface 14 can make the connector 33 stably inserted into the slot 11, and the connector 33 and the rotating shaft are stably connected; when replacing the measuring shaft 3, first disassemble the sleeve 8 and the shell 2, and slide the sleeve 8 down along the measuring shaft 3. After the measuring shaft 3 and the sleeve 8 are separated, pull the measuring shaft 3 downward, and the connector 33 comes out of the slot 11 and is pulled out of the shell 2 through the through hole 5. After the new measuring shaft 3 is inserted into the slot 11 through the through hole 5, the sleeve 8 is sleeved on the measuring shaft 3, and the sleeve 8 is locked on the shell 2 again.
