Description

Technical Field

[0001] This utility model relates to a conductivity testing device, and more particularly to a conductivity testing device for aluminum poles used in overhead conductors, belonging to the field of overhead conductor aluminum pole testing technology. Background Technology

[0002] Aluminum poles are the raw material for manufacturing overhead conductors, and the conductivity of these poles directly affects the final quality of the overhead conductor. Therefore, before production, the conductivity and other properties of the aluminum poles must be randomly inspected to ensure they meet requirements. Existing conductivity testing devices for aluminum poles typically involve manually clamping both ends of the pole to connect it to the testing device. This method is inconvenient, and manual clamping can easily lead to errors in the length of the clamped ends, resulting in inaccurate conductivity test results. Furthermore, the lack of a fixed anchor point poses a safety hazard when energized. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a device for detecting the conductivity of aluminum rods in overhead conductors, which is convenient and safe to operate and has small error.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A conductivity testing device for overhead conductor aluminum rods includes a base plate, a first aluminum rod clamp, a second aluminum rod clamp, and a conductivity testing mechanism. The first and second aluminum rod clamps are respectively disposed at both ends of the base plate. The conductivity testing mechanism is disposed on the base plate, and its two poles are respectively connected to the first and second aluminum rod clamps. The first and second aluminum rod clamps each include a clamp support, a first clamp slide, a second clamp slide, and an elastic mechanism. The first and second clamp slides are slidably disposed on both sides of the clamp support, and the elastic mechanism is disposed between the first and second clamp slides.

[0006] Furthermore, the upper end of the opposite side of the first clamp slide and the second clamp slide has a U-shaped groove that matches the aluminum rod.

[0007] Furthermore, the inner side of the clamp bracket has grooves that match the first clamp slide and the second clamp slide, and the first clamp slide and the second clamp slide are respectively slidably disposed in the grooves on both sides of the clamp bracket.

[0008] Furthermore, the lower ends of the first clamp slide and the second clamp slide are configured as wedge-shaped structures, and the bottom of the grooves on both sides of the clamp bracket are provided with inclined surfaces that match the wedge-shaped structures at the lower ends of the first clamp slide and the second clamp slide.

[0009] Furthermore, two pins are provided at the upper ends of the front and rear sides of the first and second clamp slides away from the aluminum rod, and guide grooves matching the pins are opened on the inner wall of the groove of the clamp bracket, and the guide grooves are set parallel to the inclined surface at the bottom of the groove.

[0010] Furthermore, the elastic mechanism includes a return spring, and the first clamp slide and the second clamp slide have blind holes that match the return spring on opposite sides, and the blind holes are located on the lower side of the U-shaped groove. The two ends of the return spring are respectively embedded in the blind holes of the first clamp slide and the second clamp slide.

[0011] Furthermore, the bottom of the blind hole of the first clamp slide and the second clamp slide is provided with a columnar protrusion. The columnar protrusion is arranged along the axial direction of the blind hole and the diameter of the columnar protrusion is smaller than the inner diameter of the return spring. The two ends of the return spring are respectively sleeved on the outside of the columnar protrusion of the blind hole on both sides.

[0012] Furthermore, the conductivity detection mechanism includes a housing, a power supply, an ammeter, a voltmeter, and a switch. The power supply, the switch, the first aluminum rod clamp, the second aluminum rod clamp, and the aluminum rod form a circuit. The ammeter collects the circuit current, and the voltmeter collects the voltage across the aluminum rod.

[0013] Compared with the prior art, this utility model has the following advantages and effects: This utility model provides a conductivity testing device for aluminum poles of overhead conductors. Through the unique structural design of the aluminum pole clamp, the aluminum pole only needs to be placed directly in the U-shaped groove of the clamp, and the clamp can automatically lock and fix the aluminum pole, and then perform conductivity testing. After the test is completed, the aluminum pole can be directly removed. The clamp does not require any cumbersome opening and locking operations, which is convenient and quick.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Furthermore, the technical means or technical features in the embodiments of this utility model can be replaced without creative effort. The utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 As shown, the present invention discloses an overhead conductor aluminum rod conductivity testing device, comprising a base plate 1, a first aluminum rod clamp 2, a second aluminum rod clamp 3, and a conductivity testing mechanism 4. The first aluminum rod clamp 2 and the second aluminum rod clamp 3 are respectively disposed at both ends of the base plate 1, and the conductivity testing mechanism 4 is disposed on the base plate 1, with its two poles connected to the first aluminum rod clamp 2 and the second aluminum rod clamp 3 respectively.

[0019] like Figure 2 As shown, the first aluminum rod clamp 2 and the second aluminum rod clamp 3 respectively include a clamp support 5, a first clamp slide 6, a second clamp slide 7 and an elastic mechanism 8. The first clamp slide 6 and the second clamp slide 7 are slidably disposed on both sides of the clamp support 5, and the elastic mechanism 8 is disposed between the first clamp slide 6 and the second clamp slide 7.

[0020] The upper end of the opposite side of the first clamp slide 6 and the second clamp slide 7 has a U-shaped groove 9 that matches the aluminum rod.

[0021] The inner side of the clamp bracket 5 has a groove 10 that matches the first clamp slide 6 and the second clamp slide 7. The first clamp slide 6 and the second clamp slide 7 are respectively slidably disposed in the grooves 10 on both sides of the clamp bracket 5.

[0022] The lower ends of the first clamp slide 6 and the second clamp slide 7 are configured as wedge-shaped structures, and the bottom of the grooves 10 on both sides of the clamp bracket 5 are provided with inclined surfaces that match the wedge-shaped structures at the lower ends of the first clamp slide 6 and the second clamp slide 7.

[0023] Two pins 11 are provided on the upper end of the front and rear sides of the first clamp slide 6 and the second clamp slide 7 away from the aluminum rod. A guide groove 12 matching the pins 11 is opened on the inner wall of the groove 10 of the clamp bracket 5. The guide groove 12 is set parallel to the inclined surface at the bottom of the groove 10.

[0024] like Figure 3As shown, the elastic mechanism 8 includes a return spring 13. The first clamp slide 6 and the second clamp slide 7 have blind holes 14 that match the return spring 13 on opposite sides, and the blind holes 14 are located on the lower side of the U-shaped groove 9. The two ends of the return spring 13 are respectively embedded in the blind holes of the first clamp slide 6 and the second clamp slide 7.

[0025] The bottom of the blind hole 14 of the first clamp slide 6 and the second clamp slide 7 is provided with a columnar protrusion 15. The columnar protrusion 15 is arranged along the axial direction of the blind hole 14 and the diameter of the columnar protrusion 15 is smaller than the inner diameter of the return spring 13. The two ends of the return spring 13 are respectively sleeved on the outside of the columnar protrusion 15 of the blind hole 14 on both sides.

[0026] The conductivity testing mechanism 4 includes a housing, a power supply, an ammeter, a voltmeter, and a switch. The power supply, switch, first aluminum rod clamp, second aluminum rod clamp, and aluminum rod form a circuit. The ammeter collects the circuit current, and the voltmeter collects the voltage across the aluminum rod. The power supply uses AC mains power, and the required voltage type is obtained through an internal transformer and rectifier. Alternatively, a battery can be used.

[0027] The working principle of the overhead conductor aluminum rod conductivity testing device of this utility model is as follows: The aluminum rod is directly placed in the U-shaped groove 9 of the first aluminum rod clamp 2 and the second aluminum rod clamp 3. Under its own weight, the aluminum rod presses down the first clamping slide 6 and the second clamping slide 7 of the first aluminum rod clamp 2 and the second aluminum rod clamp 3. Since the lower end of the first clamping slide 6 and the second clamping slide 7 is a wedge-shaped structure, the first clamping slide 6 and the second clamping slide 7 slide downward along the inclined surface at the bottom of the groove 9 and simultaneously slide inward and tighten. When the two side walls of the U-shaped groove 9 contact the two sides of the aluminum rod, the aluminum rod is clamped and fixed. At this time, the lower half of the aluminum rod is clamped in the U-shaped groove 9 and in close contact with the first clamping slide 6 and the second clamping slide 7. The first clamping slide 6 and the second clamping slide 7 are made of conductive material and form a circuit with the power supply and switch. After the switch is closed, the circuit is conductive. The ammeter collects the circuit current and the voltmeter collects the voltage at both ends of the aluminum rod. The conductivity of the aluminum rod is obtained by dividing the voltage by the current.

[0028] This utility model provides a conductivity testing device for aluminum poles used in overhead power lines. Through the unique structural design of the aluminum pole clamp, the aluminum pole only needs to be placed directly into the U-shaped groove of the clamp, and the clamp will automatically lock and fix the aluminum pole, and then perform conductivity testing. After the test is completed, the aluminum pole can be directly removed. The clamp does not require any cumbersome opening and locking operations, which is convenient and quick. In addition, the aluminum pole is fixed on the insulating base plate during the testing process, which enhances safety. The fixed spacing between the clamps also reduces measurement errors.
