Disclosure of Invention

In view of the above, the present invention provides an electricity larceny prevention metering cabinet convenient to install, which is convenient to install, wherein instrument equipment is installed on a transverse plate and then ascended to a proper height without transporting the equipment to a high place for installation; the setting of infrared remote alarm can open remote alarm when the cabinet door at the electricity stealing person, improves staff's irritability.

In order to achieve the purpose, the invention adopts the following technical scheme:

an anti-electricity-theft metering cabinet convenient to mount comprises a cabinet body with an opening at one end, a cabinet door is hinged at the opening of the cabinet body, a plurality of transverse plates are arranged in the cabinet body, infrared remote alarms are arranged on the transverse plates, push rods are symmetrically inserted in the transverse plates, sliding grooves for the push rods to slide up and down are arranged on the inner side wall of the cabinet body, folding rods are hinged between the push rods in the transverse plates, driving components for driving the folding rods to unfold and fold are arranged on the transverse plates, threaded rods I are arranged on two sides of the transverse plates and are connected with threaded sleeves in a threaded mode, arc-shaped grooves matched with the outer peripheral surfaces of the threaded sleeves are arranged at the end portions of the push rods, bearings I are sleeved outside the threaded rods, inner rings of the bearings I are fixedly connected with the threaded sleeves, outer rings of the bearings I are fixedly connected with the, and the control end of the direct drive motor is electrically connected with the output end of the PLC.

Furthermore, drive assembly is threaded rod two, the folding rod comprises two connecting blocks and the connecting rod that articulates in the connecting block both sides, and one of them connecting block threaded connection threaded rod two, another connecting block internal rotation connecting threaded rod two.

Furthermore, the two ends of the threaded rod are detachably connected with a crank.

Furthermore, the first threaded rod is detachably connected with the direct drive motor.

Further, a lifter is arranged below the direct drive motor, a placing groove for placing the lifter is formed in the inner bottom surface of the cabinet side plate, a connecting column is fixedly arranged on the direct drive motor, and the top end of the connecting column is connected with a key groove in the bottom end of the threaded rod.

Furthermore, the outer side wall of the cabinet body is provided with a mounting hole communicated with the direct drive motor, and the outside of the mounting hole is hinged with a closed door.

Furthermore, high-friction coatings are arranged on the outer surface of the threaded sleeve and the inner concave surface of the arc-shaped groove, and the first bearing is a deep groove ball bearing.

The metering cabinet is usually arranged in a user area, and lawless persons can open the metering cabinet, change internal connecting lines to steal electricity, and cause bad influence on a power supply party and other users; when the measuring cabinet is installed, various devices need to be conveyed to each transverse plate, for the transverse plates located at the high positions, the devices need to be moved to the high positions, and installation is difficult.

The invention has the beneficial effects that:

1. when a person stealing electricity opens the cabinet door, the infrared remote alarm on the transverse plate sends an alarm signal to a worker remotely, so that the worker can know the occurrence place of the electricity stealing behavior rapidly and can arrive at the site rapidly, and the stress of the worker is improved; and starting the direct drive motor, synchronously rotating the direct drive motor under the control of the PLC, and synchronously rotating the threaded rod. After the instrument equipment is installed on the transverse plate at the top, the crank is rotated, the folding rod extends under the driving of the second threaded rod, the two push rods are separated, the arc-shaped groove is tightly pressed and attached to the outer surface of the threaded sleeve, at the moment, the first bearing inner ring cannot rotate under the constraint of static friction between the arc-shaped groove and the threaded sleeve, the first bearing outer ring cannot rotate under the fixing action of the connecting rod, at the moment, the first threaded rod is rotated, the transverse plate moves upwards along the track of the slide way, after the transverse plate moves upwards to a proper height, the crank is rotated anticlockwise, the folding rod is shortened, the two push rods move oppositely, the arc-shaped groove is separated from the threaded sleeve, the arc-shaped groove loses the limiting effect on the threaded sleeve, the first bearing inner ring is not subjected to the force for blocking rotation, at the moment, the first threaded rod is rotated with the first bearing inner ring, the transverse plate is kept at the original height, the instrument equipment, instrument equipment is installed on the transverse plate at a lower position, then the transverse plate is lifted, the instrument equipment does not need to be transported to a high place for installation, and installation is convenient.

2. After the installation of measurement cabinet is accomplished, directly drive the motor and shelve the deactivation for a long time, threaded rod one can dismantle with directly driving the motor and be connected, can take out directly driving the motor, saves the cost, only rotates four threaded rods one simultaneously and can just unscrew the diaphragm, hardly realizes under the condition that does not directly drive the motor, effectively places the personnel of stealing the electricity and moves down the diaphragm, destroys measurement cabinet internal plant.

3. The elevator is arranged below the direct-drive motor, the placing groove for placing the elevator is formed in the bottom surface of the slide way, the fixed connecting column is arranged on the direct-drive motor, the top end of the connecting column is connected with a key groove in the bottom end of the threaded rod, the key groove is simple in connecting structure and reliable in operation, and the elevator is convenient to place the direct-drive motor.

4. The outer side wall of the cabinet body is provided with a mounting hole communicated with the direct-drive motor, the mounting hole is externally hinged with the closed door, the closed door is opened, and a user can directly place the direct-drive motor in the lower part of the threaded rod from the side surface, so that the placement is more convenient.

5. The high-friction coating is arranged on the outer surface of the threaded sleeve and the inner concave surface of the arc-shaped groove, so that the friction force between the outer surface of the threaded sleeve and the inner concave surface of the arc-shaped groove is greatly increased, an inner ring of the bearing is effectively limited, and the working reliability of the device is improved; the first bearing is a deep groove ball bearing which can bear large axial force and is suitable for the device.
