Description

Technical Field

[0001] This application relates to the technical field of pole-mounted circuit breakers, and in particular to a primary-secondary integrated complete pole-mounted circuit breaker. Background Art

[0002] A primary-secondary integrated complete pole-mounted circuit breaker is an intelligent power equipment integrating primary equipment and secondary equipment. The primary equipment uses the circuit breaker body, and the secondary equipment uses intelligent terminals such as measurement, control, and protection.

[0003] In the related art, a primary-secondary integrated complete pole-mounted circuit breaker includes a circuit breaker housing. Components such as an operating mechanism are arranged inside the circuit breaker housing, and a support plate is arranged below the circuit breaker housing.

[0004] During the process of installing the pole-mounted circuit breaker onto a cement seat cast with cement, the pole-mounted circuit breaker needs to be installed horizontally. In the case of non-horizontal installation, it will affect the operation of the operating mechanism and so on, that is, it will affect the reliability of the pole-mounted circuit breaker. However, since the cement seat is usually cast in advance, it is difficult to ensure the levelness of the upper surface of the cement seat, that is, it is difficult to ensure the levelness of the pole-mounted circuit breaker after it is installed on the cement seat. Summary of the Invention

[0005] In order to improve the levelness of the pole-mounted circuit breaker installed on the cement seat, this application provides a primary-secondary integrated complete pole-mounted circuit breaker.

[0006] A primary-secondary integrated complete pole-mounted circuit breaker provided by this application adopts the following technical solutions: A primary-secondary integrated complete pole-mounted circuit breaker includes a housing and also includes a bottom plate. The housing is arranged on the bottom plate. A first accommodation groove is opened on the end surface of the bottom plate along the length direction, and a first level gauge is arranged in the first accommodation groove. A second accommodation groove is opened on the end surface of the bottom plate along the width direction, and a second level gauge is arranged in the second accommodation groove. Four support feet are arranged below the bottom plate, and an adjusting structure for adjusting the position of the support feet is arranged on the bottom plate.

[0007] By adopting the above technical solutions, first install the pole-mounted circuit breaker on the cement seat, observe the position of the bubble in the first level gauge, and adjust the position of the support feet through the adjusting structure until the position of the bubble in the first level gauge is centered; similarly, observe the position of the bubble in the second level gauge, and adjust the position of the support feet through the adjusting structure until the position of the bubble in the second level gauge is centered, so as to realize the horizontal installation of the pole-mounted circuit breaker on the cement seat.

[0008] Optionally, the adjusting structure includes a mounting rod disposed on the support leg. A receiving hole for threaded connection of the mounting rod is formed in the lower end surface of the base plate. An adjusting nut is externally threaded on the mounting rod and located above the base plate. An adjusting spring is sleeved outside the mounting rod and located below the base plate. The adjusting spring is in a compressed state. One end of the adjusting spring abuts against the adjusting nut, and the other end of the adjusting spring abuts against the base plate.

[0009] By adopting the above technical solution, driving the mounting rod to rotate can make the mounting rod move along the axis direction of the receiving hole, so that the pole-mounted circuit breaker is horizontally installed on the cement seat. By applying a force to the adjusting nut and the base by the adjusting spring, it can play an anti-loosening effect between the mounting rod and the base.

[0010] Optionally, the support leg includes a fixed seat rotatably connected to the mounting rod. A fixing plate is rotatably connected to the side of the fixed seat away from the mounting rod. The rotation axis of the fixed seat is perpendicular to the rotation axis of the fixing plate.

[0011] By adopting the above technical solution, driving the fixed seat to rotate around the axis of the mounting rod and then driving the fixed seat to rotate can make the fixing plate fit more closely to the upper surface of the cement seat, improve the contact surface between the support leg and the horizontal seat, and make the pole-mounted circuit breaker more stable on the cement seat.

[0012] Optionally, a receiving groove communicating with the receiving hole is formed in the lower end surface of the base plate. The adjusting structure further includes a mounting tube rotatably disposed in the receiving groove. A mounting hole is formed in the end surface of the mounting tube. The mounting rod passes through the receiving hole. When the mounting tube is perpendicular to the bottom wall of the receiving groove, the mounting hole is aligned with the receiving hole.

[0013] By adopting the above technical solution, when the mounting tube and the mounting rod are both received in the receiving groove, the mounting tube and the mounting rod are stored, reducing the occupied space of the pole-mounted circuit breaker and facilitating the transportation of the pole-mounted circuit breaker. Rotating the mounting tube to be perpendicular to the bottom wall of the receiving groove and then rotating the mounting rod into the receiving hole to lock the mounting rod, making the mounting tube not easy to rotate. In addition, driving the mounting rod to move along the axis direction of the receiving hole can adjust the position of the support leg.

[0014] Optionally, a first blocking structure for blocking the first storage groove is provided on the base plate. Two first blocking chutes are formed in the bottom wall of the first storage groove and are distributed along the length direction of the base plate. The first storage groove is located between the two first blocking chutes. First blocking sliding holes communicating with the first storage groove are formed in the inner walls of the two first blocking chutes close to each other. The first blocking structure includes two first blocking strips. The two first blocking strips are respectively slidably disposed in one first blocking chute. First blocking plates penetrating through the first blocking sliding holes are disposed on the end faces of the two first blocking strips close to each other. When the two first blocking plates are in contact with each other, the first storage groove is in a blocked state.

[0015] By adopting the above technical solution, the two first plugging plates are attached to plug the first storage groove, so that dust and foreign objects are not easily introduced into the first storage groove, and at the same time, the first level is not easily contacted with the outside world, reducing the probability of damage to the first level.

[0016] Optionally, a rope body is arranged on the installation pipe, and one end of the rope body away from the installation pipe is connected to the first plugging strip.

[0017] By adopting the above technical solution, when the installation pipe rotates, it drives the rope body to move, and the rope body pulls the first plugging strip, so that the first plugging strip no longer plugs the first storage groove, enabling the construction personnel to observe the first level on the bottom plate, and enabling the staff to horizontally install the pole-mounted circuit breaker on the cement seat through the first level.

[0018] Optionally, a slot is formed in the end face of the first plugging strip away from the axis of the first storage groove, a plug rod is inserted into the slot, a deformable clamping block is arranged on the end face of the plug rod away from the bottom wall of the first plugging chute, and a clamping groove capable of allowing the clamping block to be inserted is formed in the installation pipe.

[0019] By adopting the above technical solution, during the process of the installation pipe rotating out of the accommodating groove to the outside of the accommodating groove, the installation pipe drives the first plugging strip to move by means of the rope body, that is, drives the plug rod and the clamping block to move until the clamping block abuts against the installation pipe. At this time, the installation pipe has not yet rotated to be perpendicular to the bottom wall of the accommodating groove. Continuing to drive the installation pipe to rotate, the clamping block deforms during the process of continuing to move. When the clamping block is aligned with the clamping groove, the clamping block resets and is inserted into the clamping groove, and the clamping block can limit the reverse rotation of the installation pipe.

[0020] Optionally, a plugging spring is arranged in the first plugging chute. The plugging spring is located on the side of the first plugging strip away from the first plugging plate, and the plugging spring is in a compressed state. One end of the plugging spring is fixedly connected to the inner wall of the first plugging chute away from the first plugging sliding hole, and the other end of the plugging spring is fixedly connected to the first plugging strip. A linkage chute in the shape of a long strip groove is formed on the outer circumferential surface of the installation pipe, the length direction of the linkage chute is consistent with the axis direction of the installation pipe, a linkage slider is slidably arranged in the linkage chute, the side of the rope body away from the first plugging strip is connected to the linkage slider, and a positioning member for restricting the sliding of the linkage slider is arranged on the installation pipe; when the clamping block is inserted into the clamping groove, the installation pipe is perpendicular to the bottom wall of the accommodating groove.

[0021] By adopting the above technical solution, when the positioning member limits the linkage slider, the rotation of the mounting tube can drive the first blocking strip to move, and at the same time, the movement of the first blocking strip drives the blocking spring to compress and deform, and the blocking spring applies a force to the first blocking strip in the direction of the first blocking slide hole; when the mounting tube is perpendicular to the bottom wall of the accommodating groove and the card block is inserted into the card groove, the positioning member is driven to release the limit on the linkage slider, and at this time, the blocking spring resets and drives the first blocking strip to move in the opposite direction, so that the first blocking plate can re-seal the first storage groove.

[0022] Optionally, a positioning cavity is provided on the bottom wall of the linkage slide slot, and the positioning cavity extends in a direction away from the mounting axis. A socket connected to the positioning cavity is provided on the circumferential surface of the mounting tube. The positioning member includes a positioning plate and a positioning spring arranged in the positioning cavity. The positioning spring is in a compressed state. One end of the positioning spring is fixedly connected to the inner wall of the positioning cavity away from the linkage slide slot, and the other end of the positioning spring is fixedly connected to the positioning plate. The end of the positioning plate away from the positioning spring is provided with a positioning block inserted into the linkage slide slot and a button passed through the socket.

[0023] By adopting the above technical solution, a force is applied to the button in the direction of the axis of the installation tube, and the button drives the positioning plate and the positioning block to move together, and at the same time the positioning spring is compressed and deformed until the positioning block is separated from the linkage slide slot and the positioning block no longer limits the linkage slide block. Optionally, the end surfaces of the two first blocking plates close to each other are each provided with a first groove, a first magnet is arranged in the first groove, and the two first magnets can cooperate with each other by magnetic attraction.

[0024] By adopting the above technical solution, when the two first blocking plates block the first storage slot, the two first magnets are magnetically attracted to each other to improve the stability of the connection between the two, so that the two first blocking plates are not easily separated due to accidental touch.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. First install the pole-mounted circuit breaker on the cement base, observe the position of the bubble in the first level, and adjust the position of the support leg by adjusting the structure until the bubble in the first level is centered; similarly, observe the position of the bubble in the second level, and adjust the position of the support leg by adjusting the structure until the bubble in the second level is centered, so that the pole-mounted circuit breaker can be horizontally installed on the cement base; 2. The mounting tube and the mounting rod are rotated into the receiving groove to store the mounting tube and the mounting rod. BRIEF DESCRIPTION OF THE DRAWINGS

When the second magnets 722 are magnetically attracted and matched, that is, the two second sealing plates 72 are attached to each other to seal the second storage groove 22.

[0070] Refer to Figure 5 and Figure 8 , an operation hole 28 is formed in the end face of the bottom plate 2 along the length direction, and the operation hole 28 communicates with the second sealing sliding groove 27. The operation hole 28 is in the shape of a horizontal long strip hole. An operation block 281 is slidably arranged in the operation hole 28, and one end of the operation block 281 is fixedly connected to the second sealing strip 71.

[0071] The implementation principle of Embodiment 3 is as follows: First, the installation pipe 44 is rotated out of the accommodation groove 24. Since the positioning member 6 limits the movement of the linkage slider 444, the installation pipe 44 drives the linkage slider 444 to move. The linkage slider 444 drives the first sealing strip 51, the first sealing plate 52, the insertion rod 514, and the clamping block 515 to move together, so that the first sealing plate 52 no longer seals the first storage groove 21. At the same time, the sealing spring 26 is compressed and deformed until the clamping block 515 abuts against the installation pipe 44. Continuing to drive the installation pipe 44 to rotate causes the clamping block 515 to deform. When the installation pipe 44 is perpendicular to the bottom wall of the accommodation groove 24 and the clamping block 515 is aligned with the card slot 447, the clamping block 515 resets and inserts into the card slot 447. Then, the operation block 281 is driven to move, so that the second sealing plate 72 no longer seals the second storage groove 22. Then, the installation rod 41 is rotated into the accommodation hole 23, and the first level 211 and the second level 221 are observed, and the levelness of the pole-mounted circuit breaker on the cement base is adjusted. Finally, the button 63 is pressed, so that the positioning block 62 no longer limits the movement of the linkage slider 444, and the sealing spring 26 resets to drive the first sealing strip 51 and the first sealing plate 52 to move, so that the first sealing plate 52 reseals the first storage groove 21, and the second sealing plate 72 is driven by the operation block 281 to reseal the second storage groove 22.
