Detailed ways

The technical solutions of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

A bridge field fixing device for improving stability, comprising a bridge deck and anti-collision walls 1 arranged on both sides of the top of the bridge deck, wherein a support seat 2 is poured on the outside of the anti-collision wall 1, and a light pole 3 is arranged on the support seat 2 for lighting.

As shown in FIG. 3 , the support base 2 is provided with a fixed channel 4 for the bottom end of the light pole 3 to pass through, and the size of the light pole 3 is adapted to the size of the fixed channel 4 , wherein the light pole 3 is provided with a fixed channel 4 located on the support base The support plate 5 at the top of the 2, and the support base 2 is poured with a screw 8 that penetrates the support plate 5. The support plate 5 is provided with a mounting hole 7 for the screw 8 to pass through, and the screw 8 on the top of the support plate 5 is screwed. The nut 9 is connected, and the support plate 5 is locked and fixed on the support base 2 by means of the nut 9 locking the screw rod 8, so as to realize the purpose of fixing the light pole 3 on the support base 2, and the fixing channel 4 is stuck at the same time. The bottom end of the light pole 3 expands the contact area between the two, so as to further prevent the light pole 3 from being skewed by the wind.

In this embodiment, the support plate 5 and the light pole 3 are integrally arranged, so that the support plate 5 covers the gap between the light pole 3 and the fixed channel 4 to prevent rainwater from entering the above-mentioned gap and accelerate the corrosion of the light pole 3. Thereby, the installation environment in the fixed channel 4 is improved, wherein the support base 2 on the outer side of the support plate 5 is provided with an inclined surface 6 inclined downward, so when the rainwater drops on the support plate 5 or the inclined surface 6, the rainwater will follow the inclined surface 6. Flow down to prevent rainwater from accumulating on the support base 2 and infiltrating into the gap between the lamp post 3 and the fixed channel 4 through the gap between the support plate 5 and the support base 2 .

The bottom end of the light pole 3 is located in the fixing channel 4, and the side wall of the bottom end of the light pole 3 is provided with a notch 10 for the wire 11 in the light pole 3 to pass through, and the side wall of the support base 2 is obliquely provided with a hole for the wire 11 to pass through. In this embodiment, the outlet 12 is located below the top of the notch 10 , and the top of the outlet 12 communicates with the fixed channel 4 . So that the external rainwater will not drip into the fixed channel 4 through the outlet 12 and affect its installation environment, and at the same time, the wire 11 can be clipped into the gap 10 and connected to the transmission line through the outlet 12 during installation.

As shown in FIG. 3 , a grille 13 is provided at the bottom end of the support base 2 , wherein the top of the grille 13 is provided with a coil 14 extending into the bottom end of the light pole 3 , and the inner side wall of the bottom end of the light pole 3 is provided with a The thread to which the solenoid 14 is screwed. Since the bottom end of the light pole 3 is located in the fixing channel 4, the bottom end of the light pole 3 will not abut against the grille 13 and prevent it from contacting the bottom end of the support base 2, and the grille 13 is connected to the bottom end of the light pole 3 through the solenoid 14. After screwing, the stability of the light pole 3 on the support base 2 can be further strengthened, and at the same time, the light pole 3 can be prevented from being pulled out from the fixing channel 4 without human intervention.

And because the bottom end of the light pole 3 is open and arranged, and the bottom end of the fixed channel 4 is communicated with the external space through the aperture of the grille 13, so that the outside air can flow into the fixed channel 4 and the inside of the light pole 3 through the aperture of the grille 13 to strengthen its interior. The air circulation can prevent the inner side walls of the above two from being wet and affect the installation environment, and the grille 13 can prevent small animals or impurities from entering the interior of the above two.

As a preferred solution, the top of the coil 14 is lower than the horizontal plane of the top of the notch 10 . This prevents the wire 11 from being pressed against the top of the notch 10 after the solenoid 14 is screwed onto the thread on the inner side wall of the lamp post 3, which will cause the wire 11 to be easily damaged.

The present invention has been described in detail above, but the above contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still belong to the scope of the patent of the present invention.
