[0027] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0028] See also Figures 1 to 4 This embodiment provides a pre-buried infrastructure structure for street lamps that prevents moisture penetration and corrosion, including:
[0029] The connector 1 includes a connecting screw 11, which is used for positioning and installing the street lamp pole. An external protective device 2 is provided outside the connector 1, and an internal protective component 3 is provided between the external protective device 2 and the connector 1. An embedded rod 12 is provided below the connecting screw 11, and a bent rod 13 is provided below the embedded rod 12.
[0030] The connecting screw rod 11, the embedded rod 12 and the bent rod 13 are formed by bending the same steel bar. The connecting screw rod 11 is threaded with a threading tool. The connecting screw rod 11 is used to connect with the street lamp.
[0031] Positioning plates 15 are provided at the top and bottom of the embedded rods 12 , and connecting ribs 14 are provided between the embedded rods 12 .
[0032] The positioning plate 15 is circular and has a through hole in the middle. The positioning plate 15 is welded to the embedded rod 12. The connecting ribs 14 are made of steel bars with a diameter thinner than the embedded rod 12, and the connecting ribs 14 are welded to the embedded rod 12. The embedded rods 12 are evenly arranged along the geometric center of the positioning plate 15.
[0033] The length of the bent rod 13 is three times the diameter of the embedded rod 12, and the bending radius of the bent rod 13 is three times the radius of the bent rod 13. A pressure equalizing plate 16 is provided at the bottom of the bent rod 13.
[0034] The thickness of the pressure balancing plate 16 is twice that of the positioning plate 15. The pressure balancing plate 16 is circular and has a through hole in the center. The pressure balancing plate 16 is welded to the bent rod 13. The gravity of the street lamp is transmitted to the connecting screw 11, and then to the bent rod 13 through the embedded rod 12, and finally to the pressure balancing plate 16 by the bent rod 13. The pressure balancing plate 16 is used to disperse the pressure transmitted by the bent rod 13.
[0035] The external protection device 2 is used to protect the internal protection component 3 and the connecting member 1 and disperse the weight of the street lamp post borne by the connecting member 1. The external protection device 2 includes a pressure-bearing base 21, a protection column 22 is provided on the top of the pressure-bearing base 21, and a threading hole 23 is provided in the center of the pressure-bearing base 21 and the protection column 22.
[0036] The pressure bearing base 21 and the protection column 22 are cast by concrete. The wire threading hole 23 is used for passing the wires of the street lamp.
[0037] The inner protection component 3 is used to isolate the connector 1 and the outer protection device 2 to prevent moisture erosion. The inner protection component 3 includes an end sheath 31 and a waterproof layer 32. The end sheath 31 is wrapped around the outside of the connecting screw 11, and the waterproof layer 32 is wrapped around the outside of the embedded rod 12, the bent rod 13 and the connecting rib 14.
[0038] The end sheath 31 is a plastic sheath. After the end sheath 31 is sheathed on the outside of the connecting screw 11, the end sheath 31 is shrunk by heating, thereby protecting the thread of the connecting screw 11.
[0039] The waterproof layer 32 is made of asphalt material, and the waterproof layer 32 evenly covers the outside of the embedded rod 12, the bent rod 13 and the connecting rib 14. The waterproof layer 32 can isolate the embedded rod 12, the bent rod 13 and the connecting rib 14 from contact with external water.
[0040] The inner protection assembly 3 further includes a plurality of zinc blocks 33 , which are evenly and fixedly mounted on the bottom surface of the positioning plate 15 .
[0041] The zinc block 33 is fixedly mounted on the bottom of the positioning plate 15 by welding. A galvanic cell can be formed between the zinc block 33 and the positioning plate 15. The zinc block 33 has a higher oxidizability than the positioning plate 15. When oxidation occurs, the zinc block 33 will be sacrificed, thereby protecting the positioning plate 15. Since the positioning plate 15 and the embedded rods 12 are welded, and the embedded rods 12 are fixedly connected by the connecting ribs 14, the connector 1 can be protected as a whole.
[0042] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
