[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 in conjunction with 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 is convenient for the staff to directly operate and control the movement of the circuit breaker from outside the cabinet. An operating assembly 101 is fixedly arranged outside the low-voltage cabinet. The operating assembly 101 is a small integrated platform, which integrates a rotating handle 102 and a pressing handle 103. The rotating handle 102 and the pressing handle 103 are respectively located on both sides of the operating assembly 101. After the pressing handle 103 is manually pressed down, it can cooperate with the limit mechanism 200 to unlock. The rotating handle 102 is used to insert the docking motion mechanism 300 after the limit mechanism 200 is unlocked. The staff can rotate the rotating handle 102 to control the motion mechanism 300, operate the motion mechanism 300 to translate, and place the circuit breaker on the motion mechanism 300.

[0037] The limiting mechanism 200 can lock the adjusting rod 302 in the moving 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 the matching frame 201 is located between the control mechanism 100 and the moving mechanism 300.

[0038] The inner wall of the matching frame 201 is rotatably provided with an unlocking ring 202. One side of the unlocking ring 202 is located outside the matching frame 201 and faces the pressing handle 103. When the pressing handle 103 is pushed linearly toward the matching frame 201 by the staff, it can contact the unlocking ring 202 and drive the unlocking ring 202 to rotate. The sliding block 203 is also located in the matching frame 201. The sliding block 203 itself can slide along the matching 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 is engaged with the adjustment rod 302, so that the adjustment rod 302 is locked. 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 is subsequently rotated and the motion mechanism 300 is translated.

[0039] Example 2

[0040] Reference Figures 1 to 6 This embodiment is based on the previous embodiment, and is different from the previous embodiment in that:

[0041] The outer walls of the rotating handle 102 and the pressing handle 103 are respectively provided with auxiliary seals 104, and the other ends of the auxiliary seals 104 are tightly fitted against the inner wall of the operating assembly 101. The auxiliary seals 104 can ensure that the structures 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 arranged 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 comes into play, 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, which passes through the matching frame 201 and faces the pressing handle 103. The pressing handle 103 can push the docking protrusion 202b during the linear motion, 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 a resetting elastic force. 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 slidably arranged along the inner wall of the matching frame 201. The sliding block 203 faces the side of the toggle protrusion 202c, and a slot 302a is fixedly provided to cooperate with the toggle protrusion 202c, and the toggle protrusion 202c extends into the slot 302a.

[0044] When the unlocking ring 202 rotates, it can drive the toggle protrusion 202c to rotate synchronously, and the cooperation between the toggle protrusion 202c and the slot 302a can ensure the horizontal movement of the sliding block 203. The adjusting rod 302 has a slot 302a fixedly provided on one side of 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 slot 302a, and provides a locking limit for the adjusting rod 302.

[0045] Once the sliding block 203 leaves the slot 302a, the limiting effect of the adjusting rod 302 is released, and a socket end 102a is fixedly provided at the end of the rotating handle 102 to cooperate with the front end of the adjusting rod 302. The staff can directly push the rotating handle 102 to move in a straight line, so that the socket end 102a and the front end of the adjusting rod 302 are engaged, 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 is different from the previous embodiment in that:

[0048] Two blocking holes 302b are fixedly opened on the outer wall of the adjusting rod 302, one of the blocking holes 302b is located at the tail 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 set 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 board 301a is fixedly installed at the bottom of the conveying chassis 301. The terminal board 301a is used to connect the physical lines required for the operation of the entire low-voltage cabinet. A travel switch 301a-1 is fixedly installed inside the terminal board 301a. A conduction rod 301b is slidably connected to both ends of the travel switch 301a-1. The movement of the conduction rod 301b can pull the travel switch 301a-1 to open.

[0050] Two sections of toggle push plates 301c are also slidably arranged 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 arranged 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 opened at the end of the conductive rod 301b, and a convex rod 301c-2 is also fixedly arranged on the top of the toggle push plate 301c to correspond to the buffer groove 301b-1, and the convex rod 301c-2 is inserted through the buffer groove 301b-1.

[0051] When the adjustment rod 302 starts to move and is about to move to the maximum limit, the critical indicator rod 302b-1 is about to contact the matching groove 301c-1 on the top of the push plate 301c. After the adjustment rod 302 moves to the maximum limit, the critical indicator rod 302b-1 has also entered the matching groove 301c-1, and through the contact and cooperation between itself and the matching groove 301c-1, it drives the matching groove 301c-1 to move horizontally. The linear movement of the matching groove 301c-1 is also pulled by the transmission rod 301b to move through the cooperation of the protruding rod 301c-2 and the buffer groove 301b-1, thereby activating the travel switch 301a-1 in the wiring board 301a through the transmission rod 301b.

[0052] After the travel switch 301a-1 is activated, it can play the role of signal transmission, and transmit the signal that the adjustment rod 302 moves to the extreme position to the electronic components such as the protection device in the low-voltage cabinet, thereby realizing the effect of telemetry and remote control, which is convenient for the staff outside the cabinet to directly monitor the operation status in the cabinet. If the adjustment rod 302 returns to the opposite direction, the critical indicator rod 302b-1 at its tail will also follow the movement and cooperate with the toggle push plate 301c at the rear end of the conveying chassis 301, and the travel switch 301a-1 in the wiring board 301a can also be activated.

[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 rather than to limit it. 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, which should all be included in the scope of the claims of the present invention.
