Description

Technical Field

[0001] This utility model relates to the field of power engineering testing equipment technology, specifically a voltage testing device for power engineering construction. Background Technology

[0002] In the process of power engineering construction, voltage detection is a key link to ensure construction safety and normal equipment operation. Whether it is line laying, equipment installation or later commissioning, accurate detection of voltage parameters of the power system is required.

[0003] Existing voltage testing equipment commonly available on the market mainly includes multimeters, clamp meters, and dedicated voltage testers. These devices can meet basic voltage testing needs to a certain extent. However, when performing voltage testing at higher locations, construction personnel need to frequently climb to higher places to conduct voltage testing, which affects the convenience of voltage testing at multiple points. Furthermore, the test leads are easily corroded by the environment when exposed for a long time, affecting their testing accuracy. It is also not convenient to make quick and accurate contact tests when testing voltage on cables at high locations. When testing voltage on circuits on a flat surface, it is difficult to control the contact pressure. Excessive contact pressure can damage the circuit, which is not conducive to voltage testing in different locations. Therefore, it is necessary to design a voltage testing device for power engineering construction to solve the above problems. Utility Model Content

[0007] Preferably, a limiting protrusion is fixedly connected to the outer side of the inner movable rod of the telescopic support rod, and a locking bolt is spirally connected to the upper right end of both the outer tube and the middle tube of the telescopic support rod, with the inner end face of the locking bolt fitting against the limiting protrusion.

[0011] Preferably, the lower end face of the mounting plate is provided with a V-shaped groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This voltage detection equipment for power engineering construction allows the extension or retraction of the telescopic support rod by tightening or loosening the locking bolts, thereby adjusting the height of the top frame. This enables different height supports for voltage detection in circuit construction at different heights, eliminating the need for construction personnel to repeatedly climb to high altitudes, thus improving construction safety.

During use, adjusting the screw rotates the lifting sleeve, which moves the sliding support plate and detection pen upwards for easy voltage detection.

[0013] 2. This voltage testing equipment for power engineering construction can quickly suspend cables at heights for voltage testing using a hanging plate. The lifting and lowering of the testing pen allows for rapid contact testing of the cables. When testing voltage on planar circuits, the rotating plate can be rotated by removing the positioning bolts, allowing the elastic telescopic rod and insulating pad to be positioned at the top. The positioning bolts are then screwed into the corresponding threaded holes, allowing them to contact the plane. The extension and retraction of the elastic telescopic rod allows the testing pen to slowly contact the circuit, preventing excessive pressure from damaging the circuit on the plane.

[0017] Example 1 Please refer to Figure 1-6 As shown, this utility model provides a voltage detection device for power engineering construction, including a telescopic support rod 1 and a handle 11. The upper end of the telescopic support rod 1 is fixedly connected to a top frame 2. The height of the top frame 2 can be adjusted by telescopically adjusting the telescopic support rod 1. A sliding support plate 3 is slidably connected to the middle position inside the top frame 2. A detection pen 4 is fixedly connected to the upper end of the sliding support plate 3. A rotating cover 5 is rotatably connected to the upper inner side of the top frame 2. The top frame 2 and the rotating cover 5 can seal and protect the detection pen 4. A rotating plate 6 is rotatably connected to the left end of the top frame 2, and a hanging plate 7 is fixedly connected to the upper right side of the rotating plate 6. The hanging plate 7 enables rapid suspension when voltage testing of cables at heights, ensuring control stability during high-altitude cable testing. An elastic telescopic rod 8 is fixedly connected to the lower front end of the rotating plate 6, and an insulating pad 9 is fixedly connected to the front end of the elastic telescopic rod 8. The elastic telescopic rod 8 and the insulating pad 9 can abut against the plane, and the extension and retraction of the elastic telescopic rod 8 allows the testing pen 4 to slowly contact the circuit, avoiding excessive pressure that could damage the circuit on the plane.

[0018] Specifically, a touch screen 10 is fixedly connected to the front of the lower end of the telescopic support rod 1. The touch screen 10 is electrically connected to the detection pen 4. A handle 11 is fixedly connected to the lower end of the telescopic support rod 1, which facilitates hand-holding and control of the device.

[0019] Specifically, a limiting protrusion 12 is fixedly connected to the outer side of the inner movable rod of the telescopic strut 1. Locking bolts 13 are spirally connected to the upper right end of the outer tube and the middle tube of the telescopic strut 1. The inner end face of the locking bolt 13 fits against the limiting protrusion 12. The limiting protrusion 12 can limit the inner rod of the telescopic strut 1, and the telescopic strut 1 can be extended or retracted by tightening or loosening the locking bolt 13.

[0020] Specifically, a motor 14 is fixedly connected to the lower end of the top frame 2. The motor 14 is electrically connected to the touch screen 10. An adjusting screw 15 is fixedly connected to the upper end of the output shaft of the motor 14. A lifting sleeve 16 is screwed to the outer side of the adjusting screw 15. The lifting sleeve 16 is fixedly connected to the sliding support plate 3. A rubber pad 17 is fixedly connected to the lower end face of the rotating cover 5. A torsion spring 18 is sleeved on the rotating shaft surface between the rotating cover 5 and the top frame 2. The outer torsion arm of the torsion spring 18 is fixedly connected to the rotating cover 5 and the top frame 2 respectively. By driving the motor 14 to rotate, the adjusting screw 15 can rotate, which in turn allows the lifting sleeve 16 to drive the sliding support plate 3 and the detection pen 4 to move upward and push the rotating cover 5 upward to facilitate voltage detection.

[0021] Specifically, a positioning bolt 19 is spirally connected to the lower left side of the rotating plate 6. The positioning bolt 19 is spirally connected to the top frame 2. A positioning threaded hole 20 is provided on the upper side of the left end face of the top frame 2. The positioning bolt 19 can be easily installed and removed to facilitate positioning after the rotating plate 6 rotates.

[0022] Specifically, the lower end face of the mounting plate 7 is provided with a V-shaped groove 21, which makes it easy to hang the mounting plate 7 on the outside of cables of different thicknesses.

[0023] Working Principle: This utility model is a voltage detection device for power engineering construction. When performing voltage detection in power engineering construction, the hanging plate 7 allows for rapid suspension of cables at heights, ensuring control stability during high-altitude cable testing. When detecting voltage on planar circuits, the rotating plate 6 can be rotated by removing the positioning bolt 19, allowing the elastic telescopic rod 8 and insulating pad 9 to be positioned at the top. The positioning bolt 19 is then screwed into the corresponding positioning threaded hole 20, thus contacting the plane. The extension and retraction of the elastic telescopic rod 8 allows the detection pen 4 to slowly contact the circuit, preventing excessive pressure from damaging the circuit on the plane. This allows the detection device to adapt to different circuit locations. For voltage testing, the telescopic support rod 1 can be extended or retracted by tightening or loosening the locking bolt 13, thereby adjusting the height of the top frame 2. This allows for different height support for voltage testing at different circuit construction locations, eliminating the need for construction personnel to repeatedly climb to high altitudes, thus improving construction safety. The top frame 2 and rotating cover 5 also protect the testing pen 4. During use, the touch screen 10 controls the motor 14 to rotate, which in turn rotates the adjusting screw 15. This causes the lifting sleeve 16 to move the sliding support plate 3 and the testing pen 4 upwards, and pushes the rotating cover 5 upwards for voltage testing, thereby greatly improving the efficiency of voltage testing at different locations.
