As shown in fig. 7, in the present embodiment, the seal 15 may be a rectangular elastic seal ring. Wherein, in order to avoid the sealing member 15 influencing the opening or closing of the cover plate 4, the size of the outer ring of the sealing member 15 should be smaller than that of the window 3.

For the sake of easy viewing, in fig. 2-4, the lamp post 1, the cover plate 4, the protrusion 14 and the sealing member 15 are sectioned.

As shown in fig. 2, the cover 4 is in the open position and the sound level meter 5 is in the extended position, and at this time, after the sound level meter 5 is opened, the microphone of the sound level meter 5 can receive the sound in the environment outside the lamp post 1, so that whether the noise exists can be detected.

The microphone of the sound level meter 5 needs to be protected from water ingress, otherwise abnormal conditions such as failure of noise detection may occur. In order to protect the sound level meter 5 and the microphone thereof, when the weather of rain and snow occurs, the second driving mechanism can drive the sound level meter 5 to move to the accommodating position, and then the first driving mechanism drives the cover plate 4 to move to the closing position, so that the sound level meter 5 and the microphone thereof are prevented from water entering, and the sound level meter 5 is protected.

In order to automatically detect rain and snow weather, a rain and snow sensor and a main control module can be fixedly arranged on the lamp pole 1. The rain and snow sensor is arranged outside the lamp post 1, and the position of the rain and snow sensor can be set according to requirements, but the rain and snow sensor is prevented from being shielded by components such as a lamp holder and the like; the main control module can be installed inside the lamp post 1. In this embodiment, the rain and snow sensor, the controller of the first driving mechanism, and the controller of the second driving mechanism are all electrically connected to the main control module.

Referring to fig. 2, 3 and 4, the control flow for the cover plate 4 and the sound level meter 5 when it encounters rainy or snowy weather is roughly as follows:

when the rain and snow sensor detects rain or snow, the main control module sends a first control instruction to the controller of the second driving mechanism to start the second driving mechanism, so that the sound level meter 5 is driven to move to the storage position;

when the sound level meter 5 is moved to the proper position, the main control module sends a second control instruction to the controller of the first driving mechanism, so that the first driving mechanism is started, and the cover plate 4 is driven to move to the closed position.

Sound level meter 5 on the street lamp has the function of detecting the noise, in order to realize after detecting the noise, can remind the people who sends the noise, can be provided with light reminding device on lamp pole 1, wherein, when the sound intensity that sound level meter 5 detected was greater than when predetermineeing the sound intensity, then start light reminding device.

In this embodiment, the light reminding device may be a projection lamp, and after the projection lamp is started, a text or/and a pattern for reminding the user of stopping the noise may be projected onto the ground, thereby reminding the user of the noise. After the street lamp is installed, the projection direction of the projection lamp can be debugged in advance, so that the light and shadow can be transmitted at a striking position after the street lamp is started.

When running into the weather of blowing, sound level meter 5 also probably detects the noise, in order to guarantee the degree of accuracy of detection, avoids appearing the condition of erroneous judgement, in this embodiment, can set up the anemoscope on lamp pole 1, wherein, when the wind speed that the anemoscope detected was greater than when predetermineeing the wind speed, then closed sound level meter 5.

The street lamp can be installed in areas such as a residential quarter, a square and a hotel, and under the general condition, the street lamp only needs to detect the sound at night. To detect whether noise exists in a specific time period, the following steps are performed:

step S1, acquiring the current time, and determining the relationship between the current time and a preset time period;

step S211, when the current time is the starting time of a preset time interval, judging whether the weather is rainy or snowy;

step S212, if the weather is not rainy or snowy: the first driving mechanism is started to drive the cover plate 4 to move from the closed position to the open position; when the cover plate 4 moves to the opening position, the second driving mechanism is started to drive the sound level meter 5 to move from the accommodating position to the extending position;

step S221, when the current time is within a preset time period, the cover plate 4 is kept at the opening position and the sound level meter 5 is kept at the extending position;

step S231, when the current time is not the end time of the preset time period, the second driving mechanism is started to drive the sound level meter 5 to move from the extension position to the storage position; when the sound level meter 5 moves to the storage position, the first driving mechanism is started to drive the cover plate 4 to move from the opening position to the closing position.
