Description

Technical Field

[0001] This utility model relates to the field of low-voltage electrical technology, and in particular to a horizontal manual operating mechanism and power equipment. Background Technology

[0002] Circuit breakers are generally installed vertically or horizontally inside the housing of electrical equipment. The housing can be a distribution cabinet or a high-voltage box in the new energy industry. To facilitate the opening and closing of the circuit breaker, a manual operating mechanism is usually installed inside the housing. The circuit breaker's switch handle is activated by moving the manual operating mechanism.

[0003] In the field of new energy photovoltaics, after photovoltaic energy panels absorb energy and convert it into DC power, the power needs to be stored, converted and transmitted to the power grid. The high-voltage box is one of the main front-end integrated electrical appliances in the new energy field. It integrates many low-voltage components such as fuses, contactors, disconnectors, circuit breakers and so on, and is installed in series in the energy storage container. Due to miniaturization and compactness, the operating handle outside the high-voltage box is not only perpendicular to the circuit breaker or disconnector, but is installed and controlled at multiple angles such as horizontal and vertical according to the arrangement of the components inside the high-voltage box.

[0004] In existing technology, a lateral manual operating mechanism generally includes a mounting bracket, a rotating rod, and a swing plate. The mounting bracket is mounted on the circuit breaker, and the swing plate is swayably connected to and housed within the mounting bracket. The swing plate has a limit slot, which confines the switch handle within the limit slot. The rotating rod is connected to the swing plate, and rotating the rotating rod causes the swing plate to swing, thereby actuating the switch handle. Because the swing plate needs to swing, this structure requires the mounting bracket to have a certain height to avoid interference with the swing plate. Therefore, the overall height of the circuit breaker is excessive, occupying too much space within the housing. Utility Model Content

[0005] The purpose of this invention is to provide a horizontal manual operating mechanism and power equipment that reduces height and space occupation.

[0017] The transmission assembly further includes a connecting washer and a fastener. The connecting washer is disposed on the side of the mounting plate opposite to the gear. The fastener is used to connect the connecting washer to the first boss. The connecting washer can prevent the first boss from dislodging from the rotating hole.

[0018] As an alternative, the sliding plate includes a sliding main plate and a second connecting side plate that are perpendicular to each other. The sliding main plate is slidably connected to the mounting bracket and is provided with the limiting slot. The rack is connected to the second connecting side plate.

[0023] The first direction and the second direction are perpendicular to each other.

[0024] As an alternative, along the first direction, the sliding plate has folded edges on both sides of the limiting slot, and the folded edges are used to abut against the switch handle.

[0025] The electrical equipment includes a housing, a circuit breaker, and a lateral manual operating mechanism as described in any of the above embodiments, wherein the circuit breaker is disposed within the housing, and the rotating rod passes through the housing and extends to the outside of the housing.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0039] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] like Figures 1-7As shown, this utility model embodiment provides a horizontal manual operating mechanism 1, which is applied to a circuit breaker 2.

[0043] The horizontal manual operating mechanism 1 includes a mounting bracket 11, a sliding plate 12, and a rotating rod 13. The mounting bracket 11 is mounted on the circuit breaker 2 and has a clearance opening 1111 for avoiding the switch handle 21 of the circuit breaker 2. When the mounting bracket 11 is mounted on the circuit breaker 2, the switch handle 21 is located within the clearance opening 1111, preventing interference between the switch handle 21 and the mounting bracket 11 during opening and closing. The sliding plate 12 is mounted on and slidably connected to the mounting bracket 11. The sliding plate 12 has a limit slot 1211. The switch handle 21 passes through the clearance opening 1111 and is inserted into the limit slot 1211, allowing the switch handle 21 to follow the movement of the sliding plate 12. The rotating rod 13 and the sliding plate 12 are connected by a transmission assembly 14. Rotating the rotating rod 13 can make the sliding plate 12 slide relative to the mounting bracket 11 in a first direction (the first direction is the direction in which the switch handle 21 is turned when opening and closing the circuit). That is, rotating the rotating rod 13 clockwise or counterclockwise can make the sliding plate 12 slide back and forth in the first direction, and at the same time realize the sliding plate 12 driving the switch handle 21 to open and close the circuit.

[0044] In this transverse manual operating mechanism 1, the rotating rod 13 and the sliding plate 12 are connected by a transmission assembly 14, and the sliding plate 12 is slidably connected to the mounting bracket 11. This enables the rotating rod 13 to drive the sliding plate 12 to slide in the first direction, thereby driving the switch handle 21 to open and close the circuit breaker. This avoids the problem of driving the switch handle 21 to open and close the circuit breaker by a swing plate in the prior art, reduces the height of the protruding circuit breaker 2 of the transverse manual operating mechanism 1, and reduces the space occupied.

[0045] Optionally, such as Figure 2 As shown, the transmission assembly 14 includes a gear 141 and a rack 142 that mesh with each other. The gear 141 is sleeved on one end of the rotating rod 13 and is rotatably connected to the mounting bracket 11. The rack 142 is connected to one end of the sliding plate 12 along the second direction. Through the meshing of the gear 141 and the rack 142, when the rotating rod 13 drives the gear 141 to rotate, the rack 142 can be driven to slide back and forth along the first direction. Since the rack 142 is connected to the sliding plate 12, the rack 142 drives the sliding plate 12 to slide back and forth along the first direction.

[0046] Specifically, refer to Figure 2 and combined Figure 4 As shown, a second boss 1412 is provided on one side of the gear 141. The second boss 1412 is provided with a blind hole. One end of the rotating rod 13 passes through the blind hole to realize the connection between the rotating rod 13 and the gear 141.

[0047] More specifically, the cross-sections of the rotating rod 13 and the blind hole are square. By setting the cross-sections of the rotating rod 13 and the blind hole to square, relative rotation between the rotating rod 13 and the gear 141 is avoided, making the structure more stable.

[0048] To facilitate the rotation of the rotating rod 13, refer to... Figure 1 The other end of the rotating rod 13 is provided with a rotating handle 16. Rotating the handle 16 makes the rotating rod 13 rotate, which reduces the rotational force of the rotating rod 13 and makes rotation easier.

[0049] Optionally, such as Figures 3-5 As shown, the mounting bracket 11 includes a mounting main board 111, a mounting side plate 113, and two first connecting side plates 112. The two first connecting side plates 112 are disposed at both ends of the mounting main board 111 along a first direction, and the mounting side plate 113 is disposed at one end of the mounting main board 111 along a second direction. Both the first connecting side plates 112 and the mounting side plate 113 extend toward the circuit breaker 2, and both first connecting side plates 112 are connected to the housing of the circuit breaker 2. The gear 141 is rotatably connected to the mounting side plate 113. By connecting the two first connecting side plates 112 to the housing of the circuit breaker 2, the mounting bracket 11 is mounted on the circuit breaker 2, and the mounting side plate 113 is rotatably connected to the gear 141.

[0050] The first direction (X-axis shown in the figure) and the second direction (Y-axis shown in the figure) are perpendicular to each other.

[0051] Specifically, the mounting side plate 113 is provided with a rotating hole 1131, and the gear 141 is provided with a first boss 1411 on the side opposite to the rotating rod 13. The first boss 1411 is rotatably disposed in the rotating hole 1131 so as to realize the rotatable connection between the gear 141 and the mounting side plate 113.

[0052] More specifically, the first boss 1411 is configured as a stepped structure. When the first boss 1411 is rotatably positioned within the rotating hole 1131, the mounting side plate 113 abuts against the stepped surface of the first boss 1411, and the end face of the first boss 1411 protrudes from the rotating hole 1131, meaning the end face of the first boss 1411 is higher than the mounting side plate 113. The transmission assembly 14 also includes a connecting washer 143 and a fastener 144. The connecting washer 143 is located on the side of the mounting side plate 113 away from the gear 141, and the fastener 144 is used to connect the connecting washer 143 to the end face of the first boss 1411. The connecting washer 143 can prevent the first boss 1411 from dislodging from the rotating hole 1131. In this structure, by setting the first boss 1411 to protrude from the rotating hole 1131, a certain gap is created between the connecting washer 143 and the mounting side plate 113, ensuring that the connecting washer 143 does not affect the rotation of the gear 141.

[0053] Optionally, the fastener 144 includes multiple screws, the connecting washer 143 is provided with multiple through holes, and the end face of the first boss 1411 is provided with multiple threaded holes corresponding to the through holes. The multiple screws are respectively inserted into the multiple through holes and threadedly connected to the corresponding threaded holes to realize the connection between the connecting washer 143 and the first boss 1411.

[0054] Optionally, such as Figure 6 As shown, the sliding plate 12 includes a sliding main plate 121 and a second connecting side plate 122 that are perpendicularly connected to each other. The sliding main plate 121 is slidably connected to the mounting main plate 111. The sliding main plate 121 is provided with a limit slot 1211. The second connecting side plate 122 extends away from the circuit breaker 2, and the rack 142 is connected to the second connecting side plate 122. The sliding plate 12 has a simple structure and is easy to manufacture.

[0055] Optionally, the mounting main plate 111 of the mounting bracket 11 is provided with a sliding hole 1112 extending along a first direction; the sliding main plate 121 of the sliding plate 12 is provided with a connecting hole 1213 corresponding to the sliding hole 1112. A connecting shaft 15 passes through the connecting hole 1213 and the sliding hole 1112 to allow the sliding main plate 121 and the mounting main plate 111 to be slidably connected. By sliding the connecting shaft 15 within the sliding hole 1112, the sliding plate 12 can slide relative to the mounting bracket 11 along the first direction via the connecting shaft 15.

[0056] Specifically, such as Figure 7 As shown, the connecting shaft 15 includes a first cylindrical portion 151, a second cylindrical portion 152, and a third cylindrical portion 153 arranged sequentially with gradually decreasing diameters. The second cylindrical portion 152 is slidably disposed within the sliding hole 1112. The first cylindrical portion 151 is used to abut against the mounting main board 111 to prevent the second cylindrical portion 152 from dislodging from the sliding hole 1112. The outer circumferential surface of the third cylindrical portion 153 is provided with a groove 1531. The third cylindrical portion 153 passes through the connecting hole 1213. The sliding main board 121 abuts against the second cylindrical portion 152, and a shaft retainer is provided in the groove 1531 to prevent the third cylindrical portion 153 from dislodging from the connecting hole 1213, thereby limiting the sliding main board 121. This connecting shaft 15 structure realizes the connection with the sliding main board 121 and the sliding connection with the mounting main board 111.

[0057] Furthermore, a first limiting washer is fitted on the second cylindrical portion 152, and the first limiting washer is disposed between the first cylindrical portion 151 and the mounting main board 111; a second limiting washer is fitted on the third cylindrical portion 153, and the second limiting washer is disposed between the sliding main board 121 and the shaft clip.

[0058] Optionally, such as Figures 2-3 and combined Figure 6As shown, the mounting motherboard 111 is provided with a plurality of spaced sliding holes 1112 along the second direction, and the sliding motherboard 121 is provided with a plurality of sets of connecting holes 1213 corresponding one-to-one with the sliding holes 1112. By providing a plurality of sliding holes 1112 and a plurality of sets of connecting holes 1213, the sliding motherboard 121 is made more stable when sliding, and shaking is avoided when sliding.

[0059] In this embodiment, three sliding holes 1112 are provided.

[0060] Furthermore, each set of connection holes 1213 includes at least two connection holes 1213, and each connection hole 1213 is provided with a connection shaft 15 to further improve the sliding stability of the sliding main board 121.

[0061] In this embodiment, two connecting shafts 15 are provided on the sliding holes 1112 on both sides along the second direction, and three connecting shafts 15 are provided on the sliding hole 1112 in the middle.

[0062] To prevent the sliding main board 121 from scratching the switch handle 21 at the edge of the limiting slot 1211, the sliding main board 121 is provided with folded edges 1212 on both sides of the limiting slot 1211 along the first direction. When the sliding main board 121 slides back and forth along the first direction, the folded edges 1212 on both sides can abut against the switch handle 21, effectively preventing the sharp edge of the limiting slot 1211 from scratching the switch handle 21.

[0063] This utility model embodiment also provides a power equipment, including a housing (the housing can be the distribution cabinet of a distribution cabinet or a high-voltage box in the new energy industry), a circuit breaker 2, and the aforementioned horizontal manual operating mechanism 1. The circuit breaker 2 is disposed inside the housing, and the rotating rod 13 passes through the housing and extends outside the housing, that is, the rotating handle 16 is located outside the housing, making it more convenient for the operator to operate the rotating handle 16. By setting the aforementioned horizontal manual operating mechanism 1, this power equipment can reduce the overall space occupied.

[0064] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
