Description

Technical Field

[0001] The utility model relates to the technical field of electric shock protection, in particular to a mounting structure for a direct current electric shock protection device. Background Art

[0002] Anti-power sway technology refers to the technology that prevents the power supply voltage from temporarily dropping or disappearing, so that the power supply voltage will not be interrupted in a very short time. This technology is generally used in industrial process equipment because these devices are particularly sensitive to voltage drops. Any component in the equipment will cause the entire process to stop operating due to power supply problems. Power sway protection devices are mostly placed directly in the external environment.

[0003] After searching in the public (announcement) number: CN211151735U, a mounting structure for a DC current shaking protection device is disclosed, including a mounting plate, a protection device body and a clamping device, the clamping device is fixedly installed inside the mounting plate, the protection device body is clamped with the front of the mounting plate through the clamping device, a placement plate is fixedly installed on the bottom of the mounting plate, and the bottom of the protection device body is in contact with the top of the placement plate. The mounting structure for the DC current shaking protection device can make the two clamping plates move toward or away from each other by rotating the motor, so that the mounting mechanism can clamp the shaking protection device of different specifications, and the practicability of the mounting mechanism is improved while completing the clamping of the shaking protection device. The entire installation process only needs to start the motor, avoiding the need to tighten bolts when disassembling the shaking protection device, thereby achieving the advantage of convenient installation and solving the problem of inconvenient disassembly and assembly.

[0004] Although the above scheme avoids the need to tighten bolts when disassembling and assembling the electric shock protection device, thereby achieving the advantage of convenient installation, the electric shock protection device is easily damaged due to the lack of protective measures in the external environment and is corroded by dust and rain. Therefore, we propose an installation structure for a DC electric shock protection device. Utility Model Content

[0005] The main purpose of the utility model is to provide an installation structure for a DC current sway protection device, which solves the problem that when there is a lack of protective measures in the external environment, the sway protection device is corroded by dust and rain and is easily damaged by the erosion.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A mounting structure for a DC current sway protection device, comprising a main unit, a clamping unit arranged in the main unit, a protection unit arranged above the main unit, and an auxiliary unit and a connection unit arranged on the surface of the main unit;

[0008] The clamping unit comprises a threaded shaft movably arranged in the main unit and provided with two sections of threads with opposite rotation directions, a driving motor installed at the input end of the threaded shaft, a moving groove provided on the surface of the main unit, a moving part installed on the threaded shaft, and a clamping plate installed on the side wall of the moving part and movably passing through the moving groove;

[0009] The protection unit includes a storage slot opened on the top of the main unit, a protection main board movably arranged in the storage slot, a folding slot opened on the top of the protection main board, a side panel movably arranged in the folding slot, and a flip handle installed on the surface of the protection main board.

[0010] Preferably, the main unit comprises a mounting plate, a driving cavity provided in the mounting plate, a support seat installed on the surface of the mounting plate, and a protection device body arranged on the support seat.

[0011] Preferably, the clamping unit further comprises a limiting washer installed on the inner side wall of the driving cavity, and the limiting washer is sleeved on the peripheral side surface of the threaded shaft.

[0012] Preferably, the protection unit further comprises a limit block mounted on the surface of the mounting plate, and the limit block is located above the protection device body.

[0013] Preferably, there are two groups of the integral structures consisting of the side plates and the limiting blocks, and the two groups of the integral structures consisting of the side plates and the limiting blocks are symmetrically arranged with respect to the protective device body.

[0014] Preferably, the auxiliary unit comprises an adjustment slot provided on the top of the support seat, a spring installed on the inner side wall of the adjustment slot, and a contact plate installed on the side wall adjacent to the spring and the mounting plate.

[0015] Preferably, the connection unit comprises a connection hole opened on the surface of the mounting plate, and a relay protection shell installed on the side wall of the mounting plate and located outside the drive motor.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In the utility model, by providing the clamping unit and the protection unit, when the protection device needs to be installed, the contact plate is first pressed so that the contact plate compresses the spring. At this time, the protection device body can be conveniently placed on the support seat, and then the force applied to the contact plate is removed. Under the elastic force of the spring, the contact plate fits and contacts the protection device body. At this time, the driving motor is started to drive the threaded shaft to rotate. Since the threaded shaft is provided with threads at both ends rotating in opposite directions, the two moving parts can drive the clamping plates to move along the threaded shaft in the direction of approaching each other until the clamping plates are completely aligned with the protection device. The device stops when the side wall of the device body is in contact, thus completing the contact and clamping of the protection device body. It can adapt to the installation of electric shock protection devices of different sizes. When disassembly is required, just repeat the above operation in reverse. After the installation is completed, the flip handle can be turned downward so that the flip handle is completely facing downward. At this time, the protection main board is located directly above the protection device body. Then, the side panel is turned out from the folding groove on the top of the protection main board so that the side panel touches the limit block and stops, thereby shielding the top of the protection device body, reducing the erosion of dust and rain, and extending the service life of the electric shock protection device.
