[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.
[0034] Example 1
[0035] Reference Figures 1 to 3 , this embodiment provides a waterproof circuit breaker cabinet external operating device.
[0036] The control mechanism 100 allows operators to directly operate and move the circuit breaker from outside the cabinet. An operating assembly 101 is fixed to the outside of the low-voltage cabinet. Operating assembly 101 is a small integrated platform that incorporates a rotating handle 102 and a pressing handle 103. These handles are located on either side of the operating assembly 101. When the pressing handle 103 is manually depressed, it unlocks with the limit mechanism 200. Once the limit mechanism 200 is unlocked, the rotating handle 102 inserts into the docking motion mechanism 300. Operators can rotate the rotating handle 102 to control the motion mechanism 300, operating the motion mechanism 300 for translation and placing the circuit breaker on it.
[0037] The limiting mechanism 200 can lock the adjustment rod 302 in the motion mechanism 300 in the default state. The matching frame 201 is located at the end of the pressing handle 103, inside the entire low-voltage cabinet, and between the control mechanism 100 and the motion mechanism 300.
[0038] An unlocking ring 202 is rotatably mounted on the inner wall of the mating frame 201. One side of the unlocking ring 202 is located outside the mating frame 201, facing the pressing handle 103. When the pressing handle 103 is pushed linearly toward the mating frame 201 by a staff member, it can contact the unlocking ring 202 and drive the unlocking ring 202 to rotate. A sliding block 203 is also located within the mating frame 201. The sliding block 203 itself can slide along the mating frame 201 and contact and cooperate with the unlocking ring 202. When the unlocking ring 202 rotates, it can drive the sliding block 203 to translate. In the default state, the sliding block 203 engages with the adjustment rod 302, locking the adjustment rod 302. Once the unlocking ring 202 rotates under the action of the pressing handle 103, it can drive the sliding block 203 to unlock the adjustment rod 302, thereby ensuring that the adjustment rod 302 can subsequently rotate and achieve translation of the motion mechanism 300.
[0039] Example 2
[0040] Reference Figures 1 to 6 This embodiment is based on the previous embodiment, and differs from the previous embodiment in that:
[0041] Auxiliary seals 104 are respectively provided on the outer walls of the rotating handle 102 and the pressing handle 103. The other end of the auxiliary seal 104 fits tightly against the inner wall of the operating assembly 101. The auxiliary seal 104 can ensure that the structure of the rotating handle 102 and the pressing handle 103 can still effectively isolate the external humid air. A main sealing ring 101a is fixedly installed at the bottom of the operating assembly 101, which can provide effective isolation and anti-seepage effect at the contact part between the operating assembly 101 and the low-voltage cabinet door panel.
[0042] A limiting platform 201a is fixedly installed on the inner wall of the matching frame 201, and a rotation groove 201a-1 is fixedly opened in the middle of the limiting platform 201a to accommodate the unlocking ring 202. Elastic torsion bars 202a are fixedly provided at both ends of the unlocking ring 202, and the other end of the elastic torsion bar 202a is rotationally connected to the inner wall of the rotation groove 201a-1. In the default state, the elastic force of the elastic torsion bar 202a plays a role, driving the unlocking ring 202 to rotate and stay in the initial state.
[0043] The outer wall of the unlocking ring 202 is fixedly extended with a docking protrusion 202b. The docking protrusion 202b passes through the matching frame 201 and faces the pressing handle 103. During the linear motion of the pressing handle 103, it can push the docking protrusion 202b, thereby driving the unlocking ring 202 to rotate. During the rotation of the unlocking ring 202, the elastic torsion bar 202a is also twisted, so that the elastic torsion bar 202a provides the elastic force for resetting. The other end of the outer wall of the unlocking ring 202 is also fixedly extended with a toggle protrusion 202c. The sliding block 203 itself is slidingly arranged along the inner wall of the matching frame 201. The sliding block 203 faces the side of the toggle protrusion 202c and is fixed with a slot 302a to cooperate with the toggle protrusion 202c. The toggle protrusion 202c extends into the slot 302a.
[0044] When the unlocking ring 202 rotates, it drives the toggle protrusion 202c to rotate synchronously. The cooperation between the toggle protrusion 202c and the locking slot 302a ensures the horizontal movement of the sliding block 203. The adjustment rod 302 has a fixed locking slot 302a on one side facing the sliding block 203 to limit and lock the sliding block 203. Before the sliding block 203 is driven to translate by the toggle protrusion 202c, the sliding block 203, under the action of the elastic torsion bar 202a, is tightly fitted with the locking slot 302a, while providing a locking limit for the adjustment rod 302.
[0045] Once the sliding block 203 leaves the slot 302a, the limiting effect of the adjusting rod 302 is released, and the end of the rotating handle 102 is fixedly provided with a socket end 102a to cooperate with the front end of the adjusting rod 302. The staff can directly push the rotating handle 102 for linear motion, so that the socket end 102a and the front end of the adjusting rod 302 engage with each other, thereby driving the adjusting rod 302 to rotate by rotating the rotating handle 102. The adjusting rod 302 can be a threaded structure such as a screw rod, which is arranged through the conveying chassis 301. The rotation of the adjusting rod 302 can achieve a translation effect on the conveying chassis 301.
[0046] Example 3
[0047] Reference Figures 1 to 10 This embodiment is based on the previous embodiment, and differs from the previous embodiment in that:
[0048] Two blocking holes 302b are fixedly provided on the outer wall of the adjusting rod 302, one of the blocking holes 302b is located at the tail end of the adjusting rod 302, and the other is located in the middle section of the adjusting rod 302. A critical indicator rod 302b-1 is fixedly provided in each blocking hole 302b. When the adjusting rod 302 starts to rotate and move, the critical indicator rod 302b-1 will also follow the adjusting rod 302 to perform the same movement.
[0049] A terminal block 301a is fixedly installed at the bottom of the conveying chassis 301. The terminal block 301a is used to connect the physical lines required for the operation of the entire low-voltage cabinet. A limit switch 301a-1 is fixedly installed inside the terminal block 301a. A conduction rod 301b is slidably connected to both ends of the limit switch 301a-1. The movement of the conduction rod 301b can pull the limit switch 301a-1 to open.
[0050] Two sections of toggle push plates 301c are also slidably provided at the bottom of the conveying chassis 301, and the toggle push plates 301c are respectively located at the front end and the rear end of the conveying chassis 301. The toggle push plates 301c can slide in a direction perpendicular to the adjustment rod 302. A matching groove 301c-1 is fixedly provided on the top of each toggle push plate 301c, and the matching groove 301c-1 is used to contact and cooperate with the critical indicator rod 302b-1. A buffer groove 301b-1 is fixedly provided at the end of the conduction rod 301b, and a protruding rod 301c-2 is fixedly provided on the top of the toggle push plate 301c to correspond to the buffer groove 301b-1, and the protruding rod 301c-2 is inserted through the buffer groove 301b-1.
[0051] When the adjustment rod 302 begins to move and is about to reach its maximum limit, the critical indicator rod 302b-1 is about to contact the mating groove 301c-1 at the top of the push plate 301c. After the adjustment rod 302 has moved to its maximum limit, the critical indicator rod 302b-1 has also entered the mating groove 301c-1. Through its contact with the mating groove 301c-1, it drives the mating groove 301c-1 to move horizontally. The linear movement of the mating groove 301c-1, through the interaction between the protruding rod 301c-2 and the buffer groove 301b-1, pulls the conductive rod 301b to move, thereby actuating the limit switch 301a-1 in the terminal block 301a through the conductive rod 301b.
[0052] When activated, limit switch 301a-1 transmits a signal indicating that the adjustment rod 302 has reached its limit position to electronic components within the low-voltage cabinet, such as protective devices. This enables remote sensing and remote control, allowing personnel outside the cabinet to directly monitor internal operations. If the adjustment rod 302 returns to its original position in the opposite direction, the critical indicator rod 302b-1 at its rear end will follow suit and cooperate with the push plate 301c at the rear end of the conveyor chassis 301 to similarly activate limit switch 301a-1 within the terminal block 301a.
[0053] A protective cabinet plate 105 is fixedly installed between the operating assembly 101 and the matching frame 201, which can play a protective and observation role. A moving part 304 is rotatably arranged on the side wall of the conveying chassis 301 to facilitate the rapid movement of the conveying chassis 301 through the moving part 304. The moving part 304 can be set to a variety of auxiliary movement structures.
[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
