Technical Field

[0001] The utility model relates to the technical field of power supply and distribution protection, and more specifically to a power supply and distribution alarm device. Background Art

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), which are the end - level equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. To ensure the safe use of the distribution cabinet, an audible and visual alarm is generally installed on the distribution cabinet for alarming. Usually, the audible and visual alarm is connected to sensors such as smoke sensors. When the sensor detects an abnormality inside the cabinet body, an alarm will be issued through the audible and visual alarm.

[0003] Most of the existing audible and visual alarms are cylindrical. A hole is drilled in the distribution cabinet, and the audible and visual alarm is fixedly installed in the distribution cabinet through bolts. Therefore, when disassembling and assembling the audible and visual alarm, tools are required to disassemble and assemble the bolts, which is rather inconvenient. Content of the Utility Model

[0005] The utility model provides the following technical solution: A power supply and distribution alarm device includes an audible and visual alarm main body and a distribution cabinet. An installation hole is opened on the upper surface of the distribution cabinet. The audible and visual alarm main body passes through the installation hole, and a sealing ring is fixedly connected to the surface of the audible and visual alarm main body. A sealing ring is fixedly connected to the lower surface of the sealing ring, and the lower surface of the sealing ring abuts against the upper surface of the distribution cabinet. A rotating ring is rotatably connected to the surface of the audible and visual alarm main body. An installation plate is detachably installed on the surface of the rotating ring. A smoke sensor is fixedly connected to the lower surface of the installation plate. A fixing mechanism for fixing the position of the rotating ring is installed on the inner ring surface of the rotating ring;

[0006] Two fixing blocks are fixedly connected to the surface of the audible and visual alarm main body. A T - shaped groove is opened on the side surface of the fixing block. A T - shaped positioning block is slidably connected to the inner wall of the T - shaped groove. A first connecting spring is fixedly connected to the opposite surface of the T - shaped positioning block and the T - shaped groove. The lower surface of the T - shaped positioning block is arc - shaped, and the upper surface of the T - shaped positioning block abuts against the inner top wall of the distribution cabinet.

[0007] The solution is further that the fixing mechanism includes a T - shaped insertion rod. A T - shaped groove is opened on the inner ring surface of the rotating ring. The surface of the T - shaped insertion rod abuts against the inner wall of the T - shaped groove. A second connecting spring is fixedly connected to the opposite surface of the T - shaped insertion rod and the T - shaped groove. A number of positioning counter - bores adapted to the T - shaped insertion rod are opened on the surface of the audible and visual alarm main body. The surface of the T - shaped insertion rod abuts against the inner wall of the positioning counter - bore, and the end surface of the T - shaped insertion rod is arc - shaped.

[0008] The solution further is that a concave box is fixedly connected to the surface of the rotating ring, the surface of the mounting plate is lapped with the inner wall of the concave box, mounting grooves are formed in the front and back surfaces of the mounting plate, a T-shaped plug is slidably connected to the inner wall of the mounting groove, a return spring is fixedly connected between the opposite surfaces of the T-shaped plug and the mounting groove, both sides of the T-shaped plug are arc-shaped, a connecting groove adapted to the T-shaped plug is formed in the inner wall of the concave box, the surface of the T-shaped plug is lapped with the inner wall of the connecting groove, and the smoke sensor and the main body of the sound and light alarm are electrically connected through a connecting wire.

[0009] The technical effects and advantages of the present utility model:

[0010] 1. For this power supply and distribution alarm device, the main body of the sound and light alarm is passed through the mounting hole. At this time, the fixing block passes through the mounting hole, and the sealing ring abuts against the upper surface of the power distribution cabinet. The arc surface of the T-shaped positioning block is stressed and retracted, and the T-shaped positioning block presses the first connecting spring. When the T-shaped positioning block moves into the interior of the power distribution cabinet, the elastic force of the first connecting spring pushes out the T-shaped positioning block. Since the upper surface of the T-shaped positioning block is flat, the main body of the sound and light alarm cannot be pulled out at this time, and the installation of the main body of the sound and light alarm can be completed, thus achieving the effect of convenient installation.

[0011] 2. For this power supply and distribution alarm device, the mounting plate is inserted into the concave box. At this time, the arc surface of the T-shaped plug is stressed and retracted into the mounting groove. When the T-shaped plug moves to the connecting groove, the elastic force of the return spring pushes the T-shaped plug into the connecting groove, and the installation of the mounting plate can be completed. By directly pulling the mounting plate, the arc surface of the T-shaped plug is stressed and retracted, and the mounting plate can be directly pulled out, which can avoid the phenomenon that the mounting plate blocks and cannot pass through the mounting hole when installing the main body of the sound and light alarm.

Specific embodiments

[0018] A power supply and distribution alarm device, referring to Figures 1-5 , includes a main body 1 of the sound and light alarm and a power distribution cabinet 2. An installation hole is opened on the upper surface of the power distribution cabinet 2. The main body 1 of the sound and light alarm passes through the installation hole, and a sealing ring 3 is fixedly connected to the surface of the main body 1 of the sound and light alarm. A sealing gasket 4 is fixedly connected to the lower surface of the sealing ring 3. The lower surface of the sealing gasket 4 abuts against the upper surface of the power distribution cabinet 2. A rotating ring 5 is rotatably connected to the surface of the main body 1 of the sound and light alarm, and a mounting plate 6 is detachably installed on the surface of the rotating ring 5.

[0019] A concave box 13 is fixedly connected to the surface of the rotating ring 5. The surface of the mounting plate 6 abuts against the inner wall of the concave box 13. Installation grooves are opened on the front and back surfaces of the mounting plate 6. A T-shaped insertion block 14 is slidably connected to the inner wall of the installation groove. A reset spring 15 is fixedly connected between the T-shaped insertion block 14 and the opposite surface of the installation groove. Both sides of the T-shaped insertion block 14 are arc-shaped. A connection groove adapted to the T-shaped insertion block 14 is opened on the inner wall of the concave box 13. The surface of the T-shaped insertion block 14 abuts against the inner wall of the connection groove.

[0020] Insert the mounting plate 6 into the concave box 13. At this time, the arc surface of the T-shaped insertion block 14 is forced to be received in the installation groove. When the T-shaped insertion block 14 moves to the connection groove, the elastic force of the reset spring 15 pushes the T-shaped insertion block 14 into the connection groove, and the installation of the mounting plate 6 can be completed. Directly pull the mounting plate 6, and the arc surface of the T-shaped insertion block 14 can be directly pulled out by being forced to be received, which can avoid the phenomenon that the mounting plate 6 blocks and cannot pass through the installation hole when installing the main body 1 of the sound and light alarm.

[0021] A smoke sensor 7 is fixedly connected to the lower surface of the mounting plate 6. The smoke sensor 7 is electrically connected to the main body 1 of the sound and light alarm through a connecting wire. A fixing mechanism for fixing the position of the rotating ring 5 is installed on the inner ring surface of the rotating ring 5.

[0022] The fixing mechanism includes a T-shaped insertion rod 11. A T-shaped groove is opened on the inner ring surface of the rotating ring 5. The surface of the T-shaped insertion rod 11 abuts against the inner wall of the T-shaped groove.

A plurality of positioning counterbores adapted to the T-shaped insertion rod 11 are opened on the surface of the main body 1 of the sound and light alarm. The surface of the T-shaped insertion rod 11 abuts against the inner wall of the positioning counterbore, and the end face of the T-shaped insertion rod 11 is arc-shaped.

[0023] Rotating the rotating ring 5 can drive the mounting plate 6 to rotate, thereby adjusting the position of the smoke sensor 7. When the rotating ring 5 rotates, the arc surface of the T-shaped plug 11 is forced to be received in the T-shaped groove, and the second connecting spring 12 is compressed. At this time, the T-shaped plug 11 disengages from the positioning counterbore. When the rotating ring 5 rotates, the T-shaped plug 11 rotates. When the T-shaped plug 11 rotates to other positioning counterbores, the elastic force of the second connecting spring 12 pushes the T-shaped plug 11 into the positioning counterbore to fix the position of the rotating ring 5.

[0024] Two fixing blocks 8 are fixedly connected to the surface of the main body 1 of the sound and light alarm. A T-shaped groove is formed in the side surface of the fixing block 8. A T-shaped positioning block 9 is slidably connected to the inner wall of the T-shaped groove. A first connecting spring 10 is fixedly connected to the opposite surface of the T-shaped positioning block 9 and the T-shaped groove. The lower surface of the T-shaped positioning block 9 is arc-shaped, and the upper surface of the T-shaped positioning block 9 abuts against the inner top wall of the power distribution cabinet 2.

[0025] Pass the main body 1 of the sound and light alarm through the mounting hole. At this time, the fixing block 8 passes through the mounting hole, and the sealing ring 4 abuts against the upper surface of the power distribution cabinet 2. The arc surface of the T-shaped positioning block 9 is forced to be received, and the T-shaped positioning block 9 compresses the first connecting spring 10. When the T-shaped positioning block 9 moves to the inside of the power distribution cabinet 2, the elastic force of the first connecting spring 10 at this time pushes out the T-shaped positioning block 9. Since the upper surface of the T-shaped positioning block 9 is flat, the main body 1 of the sound and light alarm cannot be pulled out at this time, and the installation of the main body 1 of the sound and light alarm can be completed. Press the T-shaped positioning block 9 to be actively received in the T-shaped groove, and the main body 1 of the sound and light alarm can be pulled out, so as to achieve the effect of convenient installation.

[0026] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
