Description

Technical Field

[0001] This utility model relates to the field of electrical protection technology, specifically to a building electrical undervoltage protection device and equipment. Background Technology

[0002] In a broad sense, building electrical engineering is an applied discipline that uses buildings as a platform and electrical technology as a means to create a humanized living environment within a limited space. In a narrow sense, it refers to the electrical systems used in buildings to create a humanized living environment by utilizing modern advanced scientific theories and electrical technologies (including power technology, information technology, and intelligent technology).

[0003] An undervoltage protection device is used to protect electrical equipment and lines from excessively low voltage. It primarily monitors the voltage level in a circuit, and when the voltage falls below a preset safety threshold, the protector will quickly activate, cutting off the circuit or taking other measures to prevent equipment damage. Some existing undervoltage protection devices are not easy to disassemble and reassemble quickly during maintenance. If the undervoltage protection device is installed at a high location or in a confined space, the maintenance difficulty is further increased.

[0004] In summary, existing building electrical undervoltage protection devices suffer from technical problems such as inconvenience in disassembly and maintenance. Utility Model Content

[0008] Protector body;

[0009] The mounting plate supports the protector body;

[0010] The first connecting component includes a first connecting block fixed to the bottom of the protector body and a second connecting block fixed to the side wall of the protector body. The side wall of the first connecting block has a first slot, and the side wall of the second connecting block has a second slot.

[0011] The second connecting assembly includes a rotating rod, a winding wheel, a first locking rod, a threaded rod, a threaded cylinder, and a second locking rod. The rotating rod is disposed in the inner cavity of the mounting plate and is fixedly connected to the winding wheel. The winding wheel is connected to the first locking rod via a pull rope. The first locking rod is embedded in the first locking groove. The threaded rod is coaxially fixedly connected to the rotating rod and the second locking rod, respectively. The threaded cylinder is fixed to the inner wall of the mounting plate and is threadedly connected to the threaded rod. The second locking rod is embedded in the second locking groove.

[0012] When the rotating rod is rotated downwards, the winding wheel retracts the pull rope, causing the first locking rod to move away from the first connecting block, and the threaded rod rotates downwards, causing the second locking rod to move away from the second connecting block.

[0013] In some embodiments of this application, a fixed plate, a movable plate, and a spring are also included. The fixed plate is fixedly connected to the inner wall of the mounting plate, and the movable plate elastically abuts against the fixed plate via the spring and is fixedly connected to the first clamping rod.

[0014] In some embodiments of this application, the fixed plate has a through hole, and the pull rope passes through the through hole and connects to the movable plate or the first clamp rod.

[0015] In some embodiments of this application, the mounting plate includes a horizontal plate and a vertical plate that are perpendicularly connected to each other. A first groove is formed on the surface of the horizontal plate, and a first connecting block is embedded in the first groove. A second groove is formed on the side wall of the vertical plate, and a second connecting block is embedded in the second groove.

[0016] In some embodiments of this application, the outlines of the first connecting block and the second connecting block are both convex blocks.

[0017] In some embodiments of this application, the convex block includes a first end and a second end opposite to each other, the first end being connected to the protector body, and the coverage area of ​​the first end being smaller than the coverage area of ​​the second end.

[0018] In some embodiments of this application, the movement direction of the first locking rod is perpendicular to the axis of the rotating rod and coincides with the axis of the first locking slot, and the first locking rod faces the opening direction of the first locking slot.

[0019] In some embodiments of this application, the movement direction of the second lever is parallel to the axis of the rotating rod and coincides with the axis of the second slot, and the second lever faces the opening direction of the second slot.

[0020] In some embodiments of this application, the mounting plate is provided with threaded mounting holes at its corners for fixing the mounting plate to a wall or electrical cabinet by bolts.

[0021] In some embodiments of this application, a rotating handle is provided at the end of the rotating rod away from the second lever.

[0022] Secondly, this application also provides a building electrical undervoltage protection device, including the building electrical undervoltage protection device as described in any embodiment of the first aspect.

[0023] Compared with the prior art, the beneficial technical effects of the technical solution provided in this application include:

[0024] This application utilizes a linked design of the first and second connecting components, allowing for rapid disassembly of the protector body by simply rotating the rotating rod, simultaneously releasing the first and second locking rods from their fixation. The use of a slot-and-locking rod mating structure eliminates the need for additional tools, significantly reducing the operational difficulty for maintenance personnel. The rotating rod synchronously controls the displacement of the first and second locking rods via a winding wheel and threaded rod, enabling the release of multi-directional fixations in a single operation, avoiding the tedious process of step-by-step disassembly and improving maintenance efficiency. This solves the problem of difficult disassembly and assembly of traditional undervoltage protection devices at heights or in confined spaces, making it particularly suitable for maintenance scenarios at heights or in restricted spaces.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0032] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose a building electrical undervoltage protection device and equipment to solve the technical problem of inconvenient disassembly and maintenance in the prior art.

[0033] To achieve the above-mentioned technical objectives, this application adopts the following technical solution:

[0034] like Figure 1 and Figure 2 As shown. In a first aspect, this application provides a building electrical undervoltage protection device, including a protector body 1, a mounting plate 2, a first connecting assembly, and a second connecting assembly.

[0035] Mounting plate 2 supports the protector body 1.

[0036] The first connecting component includes a first connecting block 3 fixed to the bottom of the protector body 1 and a second connecting block 4 fixed to the side wall of the protector body 1. The side wall of the first connecting block 3 is provided with a first slot, and the side wall of the second connecting block 4 is provided with a second slot.

[0037] The second connecting assembly includes a rotating rod 5, a winding wheel 6, a first locking rod 7, a threaded rod 9, a threaded cylinder 10, and a second locking rod 11. The rotating rod 5 is disposed in the inner cavity of the mounting plate 2 and is fixedly connected to the winding wheel 6. The winding wheel 6 is connected to the first locking rod 7 via a pull rope 8. The first locking rod 7 is embedded in the first locking groove. The threaded rod 9 is coaxially fixedly connected to the rotating rod 5 and the second locking rod 11, respectively. The threaded cylinder 10 is fixed to the inner wall of the mounting plate 2 and is threadedly connected to the threaded rod 9. The second locking rod 11 is embedded in the second locking groove. When the rotating rod 5 is rotated downward, the winding wheel 6 retracts the pull rope 8, causing the first locking rod 7 to move away from the first connecting block 3. The threaded rod 9 rotates downward, causing the second locking rod 11 to move away from the second connecting block 4.

[0038] Initial fixed state: The first locking rod 7 is inserted into the first slot of the first connecting block 3 to fix the bottom of the protector body 1. The second locking rod 11 is inserted into the second slot of the second connecting block 4 to fix the side wall of the protector body 1. At this time, the protector body 1 is firmly fixed to the mounting plate 2 by limiting it in two directions, ensuring normal operation.

[0039] Disassembly process (rotating lever 5): When it is necessary to disassemble the protector body 1, the operator rotates lever 5, which drives two mechanisms to operate simultaneously. Lever 5 drives the winding wheel 6 to rotate, winding the pull rope 8, causing the first locking lever 7 to move outward, disengaging from the first locking groove and releasing the bottom fixation. Lever 5 is coaxially fixed with the threaded rod 9, and the threaded rod 9 rotates in conjunction with the threaded cylinder 10, causing the second locking lever 11 to retract axially, disengaging from the second locking groove and releasing the side wall fixation. Because the two mechanisms operate synchronously, only one rotation operation is needed to simultaneously release the bottom and side wall fixation, allowing the protector body 1 to be easily removed.

[0040] This application utilizes a linked design of the first and second connecting components, allowing for rapid disassembly of the protector body 1 by simply rotating the rotating rod 5 to simultaneously release the fixation of the first locking rod 7 and the second locking rod 11. Due to the use of a slot and locking rod mating structure, disassembly and assembly can be completed without additional tools, significantly reducing the operational difficulty for maintenance personnel. The rotating rod 5 synchronously controls the displacement of the first locking rod 7 and the second locking rod 11 via the winding wheel 6 and the threaded rod 9, enabling the release of multi-directional fixation in a single operation, avoiding the cumbersome process of step-by-step disassembly and improving maintenance efficiency. This solves the problem of difficult disassembly and assembly of traditional undervoltage protection devices at high altitudes or in confined spaces, making it particularly suitable for maintenance scenarios at heights or in confined spaces.

[0041] In some embodiments of this application, a fixed plate 12, a movable plate 13, and a spring 14 are also included. The fixed plate 12 is fixedly connected to the inner wall of the mounting plate, and the movable plate 13 elastically abuts against the fixed plate 12 through the spring 14 and is fixedly connected to the first clamping rod 7.

[0042] This embodiment further optimizes the reset mechanism of the first locking rod 7. When the rotating rod 5 is rotated, the winding wheel 6 tightens the pull rope 8, causing the first locking rod 7 to disengage from the first locking slot. At this time, the moving plate 13 moves with the first locking rod 7 and compresses the spring 14. When the rotating rod 5 is rotated in the opposite direction, the winding wheel 6 releases the pull rope 8, and the elastic restoring force of the spring 14 pushes the moving plate 13 to reset, thereby causing the first locking rod 7 to re-lock into the first locking slot.

[0043] This design makes the reset action of the first locking lever 7 more reliable, eliminating the need for gravity or manual assistance and ensuring that it automatically returns to the locked state after disassembly. Meanwhile, the spring 14's cushioning effect reduces mechanical impact and extends the service life of the components.

[0044] In some embodiments of this application, the fixed plate 12 has a through hole, and the pull rope 8 passes through the through hole and connects to the movable plate 13 or the first clamp 7.

[0045] The through holes on the fixing plate 12 provide a precise guide path for the pull rope 8, ensuring that the pull rope 8 always moves along the predetermined trajectory during the winding and unwinding process, avoiding friction or entanglement with surrounding components.

[0046] The through-hole structure ensures the smooth transmission of the rope 8 while limiting its range of motion, preventing the mechanism from jamming due to excessive displacement.

[0047] In some embodiments of this application, the mounting plate 2 includes a horizontal plate and a vertical plate that are perpendicularly connected to each other. A first groove is formed on the surface of the horizontal plate, and the first connecting block 3 is embedded in the first groove. A second groove is formed on the side wall of the vertical plate, and the second connecting block 4 is embedded in the second groove.

[0048] Mounting plate 2 precisely positions the first connecting block 3 and the second connecting block 4 via the first and second grooves, respectively. When the protector body 1 is installed, the first connecting block 3 is embedded in the first groove of the horizontal plate to achieve lateral limitation, and the second connecting block 4 is embedded in the second groove of the vertical plate to achieve longitudinal limitation. This double-groove structure gives the protector body 1 higher stability after installation, effectively preventing vibration displacement during equipment operation, while ensuring that the first locking rod 7 and the second locking rod 11 can be accurately aligned with the corresponding slot positions.

[0049] In some embodiments of this application, the outlines of the first connecting block 3 and the second connecting block 4 are both convex blocks.

[0050] The device employs a convex block design, whose contour precisely matches the groove on the mounting plate 2. When the protector body 1 is installed, the convex block embeds into the corresponding groove, and the sidewall of the convex structure fits tightly against the inner wall of the groove, achieving multi-point contact limiting. The guiding effect of the convex block makes the installation process smoother, further improving installation accuracy and connection stability while maintaining quick assembly and disassembly characteristics.

[0051] In some embodiments of this application, the convex block includes a first end and a second end opposite to each other, the first end being connected to the protector body 1, and the coverage area of ​​the first end being smaller than the coverage area of ​​the second end.

[0052] The larger coverage area of ​​the second end creates stronger resistance to displacement within the groove, significantly improving vibration and loosening resistance. The increased contact area results in more uniform stress distribution, avoiding localized stress concentration and extending service life.

[0053] In some embodiments of this application, the movement direction of the first locking rod is perpendicular to the axis of the rotating rod 5 and coincides with the axis of the first slot, and the first locking rod faces the opening direction of the first slot.

[0054] The direction of movement of the first lever is perpendicular to the axis of the rotating rod 5 and coincides with the axis of the first slot. This orthogonal layout design allows the first lever to be precisely inserted into or removed from the first slot along a straight path.

[0055] The arrangement of the first locking lever facing the slot opening ensures that the linear alignment during insertion results in surface contact rather than point contact, improving connection strength and vibration resistance. This avoids the uneven wear issues that can occur with traditional rotary locking mechanisms.

[0056] In some embodiments of this application, the movement direction of the second lever is parallel to the axis of the rotating rod 5 and coincides with the axis of the second slot, and the second lever faces the opening direction of the second slot.

[0057] The second locking lever adopts a linear motion design parallel to the axis of the rotating rod 5, and its motion trajectory completely coincides with the axis of the second locking slot. This coaxial layout allows the second locking lever to precisely extend and retract along the axial direction of the threaded rod 9. When the rotating rod 5 rotates, it directly drives the second locking lever to insert or retract into the second locking slot via threaded transmission. The arrangement of the second locking lever facing the opening of the locking slot ensures that its end is always aligned with the locking position, forming a three-dimensional locking effect in conjunction with the vertical movement of the first locking lever. This design enables the simultaneous control of two orthogonal locking mechanisms by a single-axis rotation of the rotating rod 5, maintaining ease of operation while improving the mechanical efficiency of the second locking point through direct axial force transmission.

[0058] In some embodiments of this application, the mounting plate 2 is provided with threaded mounting holes at its corners for fixing the mounting plate 2 to a wall or electrical cabinet by bolts.

[0059] In some embodiments of this application, a rotating handle 15 is provided at the end of the rotating rod 5 away from the second locking rod 11.

[0060] The rotating handle 15 at the end of the lever 5 significantly reduces the torque required for disassembly by increasing the operating lever arm, allowing the operator to easily complete the installation and removal of the protector. The anti-slip texture on the handle surface enhances grip during operation. The handle's integrated design, coaxial with the lever 5, ensures that rotational force is directly transmitted to the winding wheel 6 and the threaded rod 9, preventing energy loss.

[0061] The rotating rod 5 has a screw groove on its side wall, and a locking bolt 16 is located at the bottom of the mounting plate 2. When the rotating rod 5 is rotated to the locked position, the locking bolt 16 is screwed into the screw groove of the rotating rod 5, forming a mechanical interlock. This design effectively solves the problem of the rotating rod 5 rotating on its own in vibration environments that may occur in traditional protection devices. The frictional force generated by the thread engagement can resist accidental rotation caused by gravity or external forces. The locking bolt 16 adopts a standard thread specification, which not only ensures sufficient locking force but also facilitates operation with conventional tools. While maintaining the advantage of quick assembly and disassembly, this structure significantly improves the working reliability of the device in building electrical vibration environments, prevents the protector body 1 from loosening due to accidental rotation of the rotating rod 5, and ensures long-term stable operation of the equipment. It is particularly suitable for applications with continuous vibration, such as high-rise buildings or industrial plants.

[0062] Secondly, this application also provides a building electrical undervoltage protection device, including the building electrical undervoltage protection device as described in any embodiment of the first aspect.

[0063] When the rotating rod 5 is rotated, on the one hand, the winding wheel 6 and the pull rope 8 drive the first locking rod 7 to disengage from the slot in the first convex block, while simultaneously compressing the spring 14; on the other hand, the threaded rod 9 and the threaded cylinder 10 work together to drive the second locking rod 11 to disengage from the slot in the second convex block, thus completely releasing the restriction on the protector body 1. During installation, simply place the protector body 1 on the mounting plate 2, allowing the convex block to enter the mounting plate 2, and then rotate the rotating rod 5 in the opposite direction to complete the fixation. The threaded mounting holes on the mounting plate 2 facilitate wall mounting. This device simplifies the disassembly and assembly process through the double locking rod linkage mechanism, significantly improving maintenance efficiency. Simultaneously, the locking structure ensures stability after installation, making it particularly suitable for the maintenance needs of building electrical equipment.

[0064] Compared with the prior art, the beneficial technical effects of the technical solution provided in this application include:

[0065] This application utilizes a linked design of the first and second connecting components, allowing for rapid disassembly of the protector body 1 by simply rotating the rotating rod 5 to simultaneously release the fixation of the first locking rod 7 and the second locking rod 11. Due to the use of a slot and locking rod mating structure, disassembly and assembly can be completed without additional tools, significantly reducing the operational difficulty for maintenance personnel. The rotating rod 5 synchronously controls the displacement of the first locking rod 7 and the second locking rod 11 via the winding wheel 6 and the threaded rod 9, enabling the release of multi-directional fixation in a single operation, avoiding the cumbersome process of step-by-step disassembly and improving maintenance efficiency. This solves the problem of difficult disassembly and assembly of traditional undervoltage protection devices at high altitudes or in confined spaces, making it particularly suitable for maintenance scenarios at heights or in confined spaces.

[0066] Those skilled in the art will understand that the steps, measures, and schemes in the various operations, methods, processes, and procedures discussed in this application can be alternated, modified, rearranged, decomposed, combined, or deleted.

[0067] The specific embodiments described above do not constitute a limitation on the scope of protection of this application.
