The force-bearing plate is rotatably installed on the top of the swing rod, and the hollow rubber is fixedly installed on the surface of the circular frame. The limit plate slides through the swing rod, and the sealing frame is fixedly installed on the surface of the swing rod. The sealing frame is connected to the hollow rubber through a pipe, and the movable plate is slidably installed inside the sealing frame. The limiting rod is fixedly installed on the surface of the movable plate. When the limiting rod moves, it will be separated from the limiting plate, so that the limiting rod cannot limit the limiting plate. The limiting plate will move downward under the action of gravity, and the limiting plate will release the limit on the force-bearing plate to avoid damage to the force-bearing plate caused by excessive wind force.

The position of the positioning plate can be limited by the elastic plate, and the positioning plate can limit the position of the circular block to prevent the circular block from moving when the device body is installed.

[0010] According to the above technical scheme, it also includes a supporting device and a power-off device. The surface of the mounting frame is provided with a supporting device, and the supporting device includes a connecting frame, a piston plate, a contact plate, a hollow plate and an expansion rubber.

The expansion rubber is fixedly mounted inside the opening, so that the friction block contacts the ground and the device body moves downward at a slower speed, thereby improving the supporting and buffering effect of the friction block on the device body.

[0011] According to the above technical solution, an exhaust port is provided inside the connecting frame, a cover plate is rotatably installed on the outer side of the connecting frame, a through hole is provided on the surface of the cover plate, an arc plate is fixedly installed on the surface of the cover plate, a support plate is fixedly installed on the bottom of the device body, and an inclined block is fixedly installed on the surface of the support plate.

[0013] According to the above technical solution, the free end of the elastic telescopic rod contacts the plug wire, the inclined plate contacts the trapezoidal plate, and the flap contacts the inclined plate, so that the elastic force of the elastic telescopic rod pushes the plug wire to separate from the connecting seat.

[0014] The present invention provides a high-efficiency and energy-saving power transformer. It has the following beneficial effects:

[0015] (1) In the invention, the force-bearing plate is arranged on the top of the device body, so that natural wind from multiple directions can blow the force-bearing plate and the swing rod to rotate. When the swing rod rotates, it will push the movable frame and the contact rod to move. When the contact rod moves, it will push the rotating shaft and the fan blades to rotate. The rotation of the fan blades will improve the heat dissipation effect of the heat sink and the device body, so that the leeward position of the device body will also be cooled, thereby improving the heat dissipation effect of the device body. When the swing rod swings at an excessively large angle, it will squeeze the hollow rubber, so that the limit plate will release the limit on the force-bearing plate, thereby preventing the force-bearing plate from being damaged by excessive wind force.

[0016] (2) In this invention, when the device body tilts after long-term use, the circular block will roll inside the hollow frame. When the circular block rolls, it will push the trapezoidal block to move. When the trapezoidal block moves, the pushing plate will push the inclined block and the L-shaped plate to move to release the limit on the friction block. The rotating plate will drive the friction block to rotate, and the friction block will rest on the support column at the edge to prevent the device body from continuing to tilt and causing danger.

[0017] (3) In this invention, when the device body quickly hits the ground, the friction block and the rotating plate will have a buffering effect on the device body. When the rotating plate rotates upward, it will push the contact plate and the piston plate to move upward. When the piston plate moves upward, it will squeeze the air inside the connecting frame and discharge it from the exhaust port. When the exhaust port cannot discharge the gas in time, the air will enter the hollow plate and push the expansion rubber to expand and restrict the movement of the piston plate, thereby improving the support and buffering effect of the friction block on the device body. When the exhaust speed of the exhaust port is too fast, it will push the cover plate and the arc rod to move upward. The upward rotation of the arc plate will push the tilting block to move. When the tilting block moves, the support plate provides auxiliary support to the device body.

[0018] (4) In this invention, when the water level at the bottom of the device body is too high, the floating block will push the flap to rotate under the action of buoyancy, and the flap will push the inclined plate to move when it rotates. When the inclined rod moves, it will push the trapezoidal plate and the positioning block to move downward to release the limit on the plug wire. The elastic telescopic rod will push the plug wire to detach from the connecting seat, preventing the device body from being disconnected from the power supply in time when water enters the bottom of the device body, which may cause danger.

When the trapezoidal block 54 moves downward, it will drive the pushing plate 59 to move downward. When the pushing plate 59 moves downward, it will contact the inclined surface of the inclined block 58, so that when the pushing plate 59 moves downward, it will drive the inclined block 58 and the L-shaped plate 57 to move.

[0035] When the embodiment is working, the flow of natural wind will blow the force-bearing plate 46 and the swing rod 43 to swing. When the swing rod 43 swings, it will push the moving frame 44 to move. When the moving frame 44 moves, it will drive the contact rod 45 to move. When the contact rod 45 moves inside the spiral groove, it will push the rotating shaft 42 to rotate. When the rotating shaft 42 rotates, it will drive the fan blades to rotate. When the fan blades rotate, they will blow wind in the direction of the heat sink 2.

When the rotating plate 55 rotates upward, it pushes the contact plate 63 and the piston plate 62 to move upward. When the piston plate 62 moves upward, it squeezes the air on the top of the piston plate 62. The air on the top of the piston plate 62 enters the interior of the hollow plate 64. The increase in the air pressure inside the hollow plate 64 pushes the expansion rubber 65 to expand.

A support plate 68 is fixedly installed on the bottom of the device body 1, and a tilting block 69 is fixedly installed on the surface of the support plate 68. When exhaust is discharged from the exhaust port, the cover plate 66 and the arc plate 67 will be blown to rotate upward, and when the arc plate 67 rotates upward, it will contact the inclined surface of the tilting block 69, so that when the arc plate 67 rotates upward, it will push the tilting block 69 and the support plate 68 to rotate. A No. 4 torsion spring is provided between the support plate 68 and the device body 1, and a No. 3 spring is provided between the piston plate 62 and the connecting frame 61.

When the flap 72 rotates, it pushes the inclined plate 73 to move. When the inclined plate 73 moves, it contacts the inclined surface of the trapezoidal plate 75, so that when the inclined plate 73 moves, it pushes the trapezoidal plate 75 and the locking rod 74 to move downward. When the locking rod 74 moves downward, it disengages from the plug wire 77 to release the limit of the plug wire 77, and the floating block 71 slides through the hollow frame 51. At the bottom of the hollow frame 51, the flap 72 is rotatably mounted inside the hollow frame 51, the inclined panel 73 slides through the inner and outer walls of the hollow frame 51, the positioning rod 74 is slidably mounted inside the mounting frame 3, the trapezoidal plate 75 is fixedly mounted on the surface of the positioning rod 74, the connecting seat 76 is fixedly mounted on the surface of the device body 1, the plug wire 77 is plugged into the inside of the connecting seat 76, and the elastic telescopic rod 78 is fixedly mounted on the surface of the device body 1 to prevent the device body 1 from being electrically disconnected in time when water enters the bottom of the device body 1, thereby preventing the device body 1 from being dangerous when water is not discharged from the bottom of the device body 1.

[0040] The free end of the elastic telescopic rod 78 contacts the plug wire 77, the inclined plate 73 contacts the trapezoidal plate 75, and the flap 72 contacts the inclined plate 73, so that the elastic force of the elastic telescopic rod 78 pushes the plug wire 77 to disengage from the connecting seat 76.

[0041] When the present embodiment is working, when the mounting frame 3 and the device body 1 fall to the ground, the friction block 56 and the rotating plate 55 will support and cushion the device body 1. After the friction block 56 contacts the ground, the friction block 56 will rotate toward the device body 1. When the rotating plate 55 rotates upward, it will push the contact plate 63 and the piston plate 62 to move upward. When the piston plate 62 moves upward, it will squeeze the air on the top of the piston plate 62. The air on the top of the piston plate 62 will enter the interior of the hollow plate 64. The increase in the air pressure inside the hollow plate 64 will push the expansion rubber 65 to expand. When the expansion rubber 65 expands, it will limit the piston plate 62 and the contact plate 63 from moving upward, so that the contact plate 63 will reduce the speed of the rotating plate 55 and the friction block 56 rotating upward. When the piston plate 62 moves upward, it will squeeze the air to be discharged from the exhaust port. When the exhaust port is exhausted, it will blow the cover plate 66 and the arc plate 67 to rotate upward. When the arc plate 67 rotates upward, it will contact the inclined surface of the tilting block 69, so that when the arc plate 67 rotates upward, it will push the tilting block 69 and the support plate 68 to rotate, so that the support plate 68 can improve the effect of supporting and buffering the device body 1;

[0042] When water accumulates at the bottom of the device body 1, the height of the accumulated water will increase and push the floating block 71 to move upward. When the floating block 71 moves upward, it will push the flap 72 to rotate. When the flap 72 rotates, it will contact the inclined surface of the inclined plate 73, so that when the flap 72 rotates, it will push the inclined plate 73 to move. When the inclined plate 73 moves, it will contact the inclined surface of the trapezoidal plate 75, so that when the inclined plate 73 moves, it will push the trapezoidal plate 75 and the locking rod 74 to move downward. When the locking rod 74 moves downward, it will disengage from the plug wire 77 to release the limit on the plug wire 77, so that the elastic force of the elastic telescopic rod 78 will push the plug wire 77 to disengage from the connecting seat 76 to disconnect the power supply of the device body 1.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
