Description

Technical Field

[0001] The present invention relates to the technical field of electric power engineering, and in particular to a primary-secondary integrated pole-mounted circuit breaker that is easy to assemble and disassemble. Background Art

[0002] With the rapid development of my country's economy and the continuous increase in electricity supply, coupled with the increasing dependence of various users on electricity, in order to effectively improve the stability and reliability of power supply of the power grid, pole-mounted circuit breakers are often used in the connection, segmentation and branch links of the power grid to strengthen the power supply guarantee capability of the power grid.

[0003] The pole-mounted circuit breakers currently sold on the market have certain inconveniences in the installation process. Normally, during installation, the bracket must be installed on the pole first, and then the circuit breaker is placed on the bracket and fixed to achieve the short-circuit protection function. However, given that the height of the poles is generally high, when placing the circuit breaker on the bracket, it is often necessary to use lifting equipment to lift it before placing it.

[0004] Since the bracket is usually made of metal and the bottom of the circuit breaker is also mostly made of metal, after the pole-mounted circuit breaker is placed, the circuit breaker is very likely to move during the operation of the staff, which in turn causes the installation position to deviate. Summary of the Invention

[0005] In response to the above technical problems, the present invention discloses a primary and secondary fusion pole-mounted circuit breaker that is easy to disassemble and assemble, which can effectively solve the problems in the background technology. During use and installation, the limiting base plate of the present invention can be telescopically expanded, thereby being able to adapt to different widths of the triangular bracket, so that the circuit breaker base is firmly installed on the triangular bracket. At the same time, after the limiting base plate is adjusted to the width corresponding to the triangular bracket, the clamping plate can be slid to both sides in a tool-free manner so that the round rod on the clamping plate is clamped into the round hole on the triangular bracket, thereby completing the fixation of the circuit breaker base. During use, the present invention does not need to rely on lifting equipment to install the device on the electric pole. The triangular bracket can be raised to a specified height by manually cranking a short worm gear. After reaching the specified height, the extrusion slider is clamped in the clamping slot of the connecting frame to squeeze and fix the connecting frame, so that the device will not fall.

[0031] In an optional implementation of the embodiment of the present invention, Figure 6 As shown, the outer surface of the roller 21 is made of hard rubber.

[0032] Working principle: When the present invention is used and installed, the limiting base plate 4 can be telescopically expanded, so as to adapt to different widths of the triangular bracket 1, so that the circuit breaker base 3 is firmly installed on the triangular bracket 1. At the same time, after the limiting base plate 4 is adjusted to the width corresponding to the triangular bracket 1, the clamping plate 10 can be slid to both sides in a tool-free manner, so that the round rod on the clamping plate 10 is clamped into the round hole on the triangular bracket 1, thereby completing the fixation of the circuit breaker base 3; when the present invention is in use, there is no need to use lifting equipment to install the device on the electric pole. It is only necessary to manually crank the short worm 23 to raise the triangular bracket 1 to a specified height. After reaching the specified height, the extrusion slider 18 is clamped in the slot of the connecting frame 15 to squeeze and fix the connecting frame 15, so that the equipment will not fall.

[0033] When the present invention is in use, the circuit breaker base 3 is first installed on the triangular bracket 1, and the circuit breaker base 3 is lifted onto the triangular bracket 1. The limiting base plate 4 will contact the gap between the triangular bracket 1. By adjusting the expansion width of the limiting base plate 4, it can be closely fitted with the triangular bracket 1. The long worm 12 is manually rotated to drive the cam 13 to rotate, so that the cam 13 pushes the limiting base plates 4 on both sides to both sides, so that the limiting base plates 4 are tightly fitted with the triangular bracket 1. Then, the threaded rod I 7 is rotated to drive the long connecting rod 8 to slide inward. The long connecting rod 8 drives the clamping plate 10 to expand to both sides through the short connecting rod 9. The round rod on the clamping plate 10 will expand to both sides, pass through the round hole on the limiting base plate 4, and clamp into the round hole on the triangular bracket 1, thereby fixing the limiting base plate 4 on the triangular bracket 1. The installation and disassembly are very convenient.

[0034] After the circuit breaker base 3 is installed, the triangular bracket 1 needs to be installed on the pole and raised to the specified height. First, the triangular bracket 1 and the fastening rod 14 are put on the pole and tightened. At this time, the pole will not be stuck. Then, the threaded rod III 25 is rotated. The threaded rod III 25 will rotate inward, thereby pushing the sliding frame 22 inward, so that the roller 21 is tightly fitted with the pole. By manually rotating the short worm 23, the driven worm gear 24 will be driven to rotate, thereby driving the roller 21 to rotate. The roller 21 is fitted with the pole, thereby driving the entire device to slide upward. When it slides to the specified height, the upper and lower threaded rods II 16 are rotated. The threaded rod II 16 drives the lifting slider 19 to slide, so that the extrusion slider 18 slides into the groove on the connecting frame 15 until the extrusion slider 18 is squeezed between the connecting frame 15 and the pole. The fixation is completed, and then the threaded rod III 25 is rotated to loosen the sliding frame 22 and release the contact between the roller 21 and the pole.
