Description

Technical Field

[0001] This invention relates to the field of rectifiers, and more particularly to a rectifier. Background Technology

[0002] A rectifier is made of vacuum tubes, ignition tubes, solid silicon semiconductor diodes, mercury arcs, etc. Its main function is to convert alternating current into direct current, which is then filtered and supplied to the load, or to the inverter and to provide charging voltage for the battery. It can be used for power supply devices and to detect radio signals. Due to the limitations of the usage conditions, some rectifiers need to be installed outdoors. However, existing rectifiers do not have rainproof function. If rainwater enters the rectifier, it can easily cause a short circuit, affecting the rectifier and the equipment that needs to be powered. Summary of the Invention

[0003] In view of this, the technical problem to be solved by the present invention is to provide a rectifier that can automatically shield the rectifier during rainstorms.

The top rod can slide out inside the vent pipe. A spring is provided between the inner wall of the vent pipe and the top plate.

[0005] The expansion bag contains absorbent resin.

[0006] The outer part of the expansion bag is made of cotton cloth.

[0021] The present invention will be described in detail with reference to the accompanying drawings in the embodiments of the present invention.

[0022] See Figure 1-5 and Figure 9 The diagram illustrates an embodiment of the present invention that automatically blocks the rectifier during heavy rain. Further,

[0023] A rectifier includes a mounting frame 301 and a main body 101. The main body 101 is fixedly connected to the mounting frame 301 by bolts. A control panel 102 is provided on the main body 101. A baffle 201 is rotatably connected to the main body 101 via a shaft. Two torsion springs 203 are fixedly connected to the rotatable connection between the baffle 201 and the main body 101. A retaining plate 302 is fixedly connected to the mounting frame 301 by bolts. An elastic sheet 202 is fixedly connected to the baffle 201 by bolts. A vent pipe 401 is fixedly connected to 01 by bolts. Multiple vent grooves 402 are opened on the vent pipe 401. An expansion bag 403 is installed inside the vent pipe 401. One end of the expansion bag 403 is glued and fixedly connected to a top plate 404. The top plate 404 is slidably connected inside the vent pipe 401. A top rod 405 is fixedly connected to the top plate 404 by bolts. The top rod 405 can slide out inside the vent pipe 401. A spring 406 is provided between the inner wall of the vent pipe 401 and the top plate 404.

[0024] When using the rectifier, rotate the baffle 201 upwards so that the baffle 201 is in a horizontal state. At this time, the two torsion springs 203 are under force, so that the baffle 201 has a downward rotation tendency. The elastic sheet 202 on the baffle 201 contacts and contracts with the clamping plate 302. When the elastic sheet 202 is located at the lower end of the clamping plate 302, the elastic sheet 202 automatically extends, and then the elastic sheet 202 can be locked at the lower end of the clamping plate 302, so that the baffle 201 remains in a horizontal state, allowing the control panel 102 on the main body 101 to be exposed, which is convenient for the user to operate and observe.

[0025] When encountering heavy rain, rainwater seeps into the interior of the vent pipe 401 through multiple vent grooves 402. The expansion bag 403 absorbs the rainwater and expands, causing the top rod 405 to slide inside the vent pipe 401. This causes the top rod 405 to slide out, while the spring 406 is compressed. The top rod 405 extends and contacts the elastic plate 202, causing the elastic plate 202 to contract. As a result, the elastic plate 202 disengages from the clamping plate 302. Under the action of the two torsion springs 203, the cover 201 automatically rotates downward to shield the main body 101 and the control panel 102, preventing rainwater from entering the rectifier and causing a short circuit.

[0026] When the rainstorm ends, the moisture inside the expansion bag 403 evaporates naturally through multiple ventilation slots 402, and the volume of the expansion bag 403 decreases. As a result, the top rod 405 can automatically reset under the action of the spring 406. At this time, the user rotates the cover 201 upward, and the elastic piece 202 can be re-locked at the lower end of the plate 302, keeping the cover 201 in a horizontal state.

[0027] See Figure 4-5 The diagram shows an embodiment in which the expansion bag 403 according to the present invention has good water absorption performance. Further,

[0028] The expansion bag 403 contains absorbent resin, which has good water absorption properties and the absorbed water can evaporate naturally.

[0029] See Figure 5 The diagram shows an embodiment in which the expansion bag 403 according to the present invention has good air and water permeability. Further,

[0030] The outer part of the expansion bag 403 is made of cotton fabric, which has good air and water permeability, making it easy for the absorbent resin to absorb and evaporate moisture.

[0031] See Figure 6 and Figure 10 A schematic diagram of an embodiment of the present invention, which enables the transmission of converted direct current, is shown. Further,

[0032] The lower end of the main body 101 is provided with a connection port, into which a connector 103 is inserted, and a connecting wire 107 is fixedly connected to the connector 103.

[0033] Insert connector 103 into the connector port on main body 101. The main body 101 converts AC power into DC power, which is then transmitted and used through connector 103 and connector 107.

[0034] See Figure 10 A schematic diagram of an embodiment of the present invention that enables automatic power-off is shown. Further,

[0035] The lower end of the cover 201 is fixedly connected to a support rod 205 by bolts, and a contact plate 204 is fixedly connected to the support rod 205 by bolts. The lower end of the connector 103 is fixedly connected to a contact rod 105 by bolts.

[0036] When the shield 201 is affected by heavy rain and rotates downward automatically, the shield 201 drives the support rod 205 and the contact plate 204 to rotate downward. When the shield 201 covers the main body 101, the contact plate 204 comes into contact with the contact rod 105 at the lower end of the connector 103. The contact plate 204 drives the contact rod 105 to move backward, so that the contact rod 105 drives the connector 103 to disengage from the connection port on the main body 101, thereby realizing the function of automatic power cut-off and avoiding the impact of heavy rain on equipment that needs power supply.

[0037] See Figure 10 A schematic diagram of an embodiment of the present invention capable of receiving connector 103 is shown. Further,

[0038] The lower end of the main body 101 is fixedly connected to a receiving platform 107 by bolts. A limiting groove 104 is opened on the receiving platform 107, and the contact rod 105 is slidably connected in the limiting groove 104.

[0039] When the contact plate 204 contacts the contact rod 105, the contact rod 105 slides within the limiting groove 104, ensuring that the connector 103 can move linearly backward and disengage from the connection port.

[0040] The receiving platform 107 serves to receive the connector 103. When the connector 103 is detached from the connector port, it will automatically fall onto the receiving platform 107 and will still be protected by the cover 201.

[0041] See Figure 7 A schematic diagram of an embodiment according to the present invention is shown, which can prevent damage to the connection between the connector 103 and the connector port. Further,

[0042] The support rod 205 is made of elastic rubber. When the contact plate 204 comes into contact with the contact rod 105, the support rod 205 can bend adaptively to ensure that the connector 103 moves backward in a straight line and prevent damage to the connection between the connector 103 and the connection port.

[0043] See Figure 8 A schematic diagram of an embodiment in which the shield 201 is made rust-resistant according to the present invention is shown. Further,

[0044] The cover 201 is made of plastic, which has rust-proof properties and can prevent rainwater corrosion.

[0045] See Figure 7-8 This illustrates an embodiment of the invention in which the elastic sheet 202 possesses good elasticity. Further,

[0046] The elastic sheet 202 is made of spring steel. The elastic sheet 202 made of spring steel has good elasticity, which can extend the service life of the elastic sheet 202.

[0047] See Figure 3 This illustrates an embodiment of the invention in which the fixing bracket 301 can be fixed. Further,

[0048] The mounting bracket 301 has multiple mounting holes. By inserting bolts into the mounting holes, the mounting bracket 301 can be fixed to an outdoor wall or bracket.
