DETAILED DESCRIPTION
[0026] like Figure 1-Figure 4 As shown, a rainproof electric energy metering box comprises an electric meter box 1, a box cover 4 is hinged at the opening of the electric meter box 1, a sealing gasket 24 is fixedly installed on the outer surface of the box cover 4, a partition 8 is fixedly installed on the top outer surface of the electric meter box 1, and a rainproof structure is fixedly installed on the top of the partition 8;
[0027] The rainproof structure includes a safety cover 15, which is fixedly mounted on one end of the top of the partition 8. A fixing plate 12 is fixedly mounted on one side of the outer surface of the safety cover 15 and the top of the partition 8. Two multi-section telescopic rods 6 are fixedly mounted on the top of the fixing plate 12. A motor 13 is fixedly mounted inside the safety cover 15. A fixed end of a rain cloth 21 is fixedly mounted on the top of the safety cover 15. Two openings 18 are opened on one side connected to the safety cover 15. A rolling structure is fixedly arranged in both openings 18. A rope drum 10 is fixedly mounted on the driving end of the motor 13. A rope 7 is wound around the outer surface of the rope drum 10.
[0028] The multi-section telescopic rod 6 includes multiple movable rods, and two adjacent movable rods are slidably connected, and the ends of the rope 7 are fixedly connected to the adjacent movable rods. The two movable rods at the ends are commonly fixedly connected to a storage structure, and the movable end of the storage structure and the top of the safety cover 15 are commonly fixedly connected to a rain cloth 21.
[0029] The outer surfaces of both sides of the electric meter box 1 are provided with a plurality of heat dissipation openings 19. The heat dissipation openings provided on both sides can dissipate the heat inside the electric meter box to prevent high temperature from being generated inside and causing danger.
[0030] like Figure 5 As shown, the storage structure includes a storage tube 20, a fixing rod 11 is fixedly installed inside the storage tube 20, a spiral spring 16 is fixed on the outer surface of the fixing rod 11, a tarpaulin 21 is fixedly connected to the connecting end of the spiral spring 16, and a groove 14 is opened on one side of the storage tube 20. The fixing rod fixes the internal spiral spring, and the spiral spring will tighten after the tarpaulin is pulled out of the groove, and then the spiral spring releases the elastic force to pull the tarpaulin back synchronously after the storage structure is pulled back by the rope, and then it is stored in the storage tube.
[0031] like Figure 6-Figure 7 As shown, the rolling structure includes a fixed column 22, which is fixedly mounted on the inner wall of the safety cover 15, and a guide wheel 23 is rotatably sleeved on the outer surface of the fixed column 22, and the guide wheel 23 is in contact with the surface of the rope 7. After the rope comes out of the rope drum, it will turn at the rolling structure, and the guide wheel of the rolling structure can guide the rope to prevent the rope from directly rubbing against the safety cover at the opening.
[0032] The two ends of the bottom of the electric meter box are respectively provided with an inlet and an outlet. The inlet and outlet arranged at the bottom can prevent rainwater from entering the inside of the electric meter box from top to bottom.
[0033] A remote switch 17 is fixedly installed on one side of the motor 13. The remote switch can be used to open the rainproof structure when it rains, and then the controller remotely controls the switch to turn on the motor to start the rainproof structure to run, and then protect against rain.
[0034] The meter box 1 and the box cover 4 are equipped with a lock buckle, which includes a mother buckle and a sub buckle, and the mother buckle is fixedly connected to the meter box 1, and the sub buckle is fixedly connected to the box cover 4. After the meter box and the box cover are closed, a lock is fastened at the middle hole of the mother lock and the sub lock to protect the meter box.
[0035] During use: when it rains, the controller controls the remote switch 17 to start the motor 13. After starting, the motor 13 will rotate the rope-taking drum 10 at the driving end, and the rope-taking drum 10 will release the rope 7 without providing tension to the rope 7. The rope 7 will turn under the action of the guide wheel 23 in the rolling structure. Then the storage structure connected to the end of the rope 7 will automatically fall down without the pulling of the rope 7, and will slide downward in an inclined manner under the support of the multi-section telescopic rod 6. In the process of the multi-section telescopic rod sliding the 6 storage structure downward, the rain cloth 21 will be pulled out from the groove 14. At this time, the rain cloth 21 will cause tension to the volute spring 16. The volute spring 16 will automatically tighten after being caused to have tension. After the multi-section telescopic rod 6 slides to a certain distance, the controller controls the remote switch 17 to turn off the motor 13. At this time, the motor 13 will no longer provide tension to the rope-taking drum 10. Drive, the rope reel 10 fixes the rope 7, and the rope 7 is no longer released. After the end of the multi-section telescopic rod 6 receives the pulling force of the rope 7, it stops sliding downward and is fixed. After the rain stops, the controller controls the remote switch 17 again to start the motor 13. The driving end of the motor 13 rotates the rope reel 10 to retract the rope 7. The rope 7 is turned by the guide wheel 23 at the rolling structure and pulls the end of the multi-section telescopic rod 6. The multi-section telescopic rod 6 slides upward after being subjected to the pulling force of the rope 7 and pulls the storage structure back together. At this time, the volute spring 16 in the storage structure no longer releases its own elastic force after being subjected to external pulling force, and then pulls the tarpaulin 21 back into the storage structure. Finally, the rope 7 pulls the multi-section telescopic rod 6 back to the initial position, and the controller controls the remote switch 17 to turn off the motor 13, and the rope reel 10 forms a pulling force to fix the rope 7 again.
[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
