Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of street lamps, and more particularly to a smart street lamp with an electrically pluggable module. BACKGROUND

[0002] With the rapid development of smart city construction, as an important node of the city Internet of Things, the function of the smart street lamp has far exceeded the traditional lighting category. Modern smart street lamps generally integrate environmental monitoring sensors (such as temperature and humidity, air quality, noise), video acquisition units, information display screens, public broadcasting loudspeakers, and wireless communication units (such as 5G micro base stations, Wi-Fi hotspots) and other electronic devices. These devices all need to be electrically connected to the electrical installation plate. Since maintenance is required, the electrical installation plate is generally fixedly installed in the base, and the base has a maintenance door, so that the maintenance door is opened to facilitate the installation of the electrical installation plate.

[0003] However, this arrangement has the following problems: 1) In order to facilitate maintenance, the maintenance door is generally arranged at a lower position of the base, and therefore the electrical installation plate is also arranged at a lower position in the base. In this case, if the city is flooded or has accumulated water, the electrical installation plate at the lower position is at risk of being flooded. Moreover, since the maintenance door needs to be frequently opened and closed, if the maintenance door is not tightly sealed, the electrical installation plate is at risk of being damp in rainy weather. 2) The electrical installation plate is arranged at a lower position of the base and is generally rigidly connected to the base, so that if the base of the street lamp is hit by a vehicle, even a slight impact will have a great impact on the electrical installation plate. 3) The electrical installation plate generates heat during use, especially in high-temperature weather, and has a problem of insufficient heat dissipation capacity. The existing base lacks active heat dissipation equipment, and if a conventional air cooling heat dissipation method is used, there is a problem of air circulation between the inside and outside of the base, which causes the risk of moisture from the outside air. SUMMARY

[0004] The present application aims to overcome the defects of the prior art and provide a smart street lamp with an electrically pluggable module.

[0005] In order to achieve the above-mentioned purpose, the present application provides the following technical solution: a smart street lamp, comprising a base, a lamp pole fixedly connected to the base, an LED lighting unit installed at the lamp pole, a first mounting seat fixedly installed at the lamp pole, a second mounting seat fixedly installed at the lamp pole, a third mounting seat fixedly installed at the lamp pole, and a plurality of functional modules; each functional module is connected to a plug unit through an electric cable; the base has a first maintenance door and a second maintenance door, the base is provided with a mounting rack, the mounting rack is provided with an electrical installation plate, and the electrical installation plate is provided with a control module and a plurality of socket units.

[0010] Furthermore, a noise sensor and a micro base station unit are also installed at the light pole.

[0011] Further, the base includes a front panel, a back panel, and two side panels; a connecting horizontal plate and two connecting horizontal bars are fixedly connected between the two side panels, and a fixed vertical plate is connected between the two connecting horizontal bars; each side panel is fixed with a limit frame, the limit frame including two limit vertical bars, two limit horizontal bars, and a limit connecting block connecting the tops of the two limit vertical bars, forming a lifting limit channel between the two limit vertical bars, and a lifting frame installed between the two limit frames, the lifting frame including a lifting seat that can move up and down along the two lifting limit channels, a lifting vertical plate fixedly connected to the lifting seat, and a lifting horizontal plate connected to the lifting vertical plate, the lifting vertical plate having a top groove, and a guide roller installed in the top groove; both side panels have an inner rectangular groove and an outer rectangular groove, a silicone heat-conducting pad is installed in the inner rectangular groove, and a guide roller is installed in the outer rectangular groove. The device is equipped with a heat-conducting block; the connecting horizontal plate is hinged to a first hinge rod, the first hinge rod is hinged to a second hinge rod, and the second hinge rod is hinged to a lifting support plate; the mounting frame is connected to the lifting horizontal plate via a first spring and to the lifting support plate via a second spring; the back plate is connected to a first abutting plate via a third spring, the first abutting plate having two first abutting protrusions; the first maintenance door is fixed with a connecting frame, the connecting frame is connected to a second abutting plate via a fourth spring, the second abutting plate having two second abutting protrusions; both sides of the mounting frame have a top slot and a bottom slot, and both sides of the mounting frame are equipped with heat-conducting frames, the heat-conducting frames including a U-shaped heat-conducting seat, a top insert plate inserted into the top slot, a bottom insert plate inserted into the bottom slot, a fifth spring connected to the top insert plate, and a sixth spring connected to the bottom insert plate.

[0012] Therefore, the silicone thermal pad is located on the inside of the side panel, and the thermal block is located on the outside of the side panel, which is made of metal, thus achieving better heat conduction. Furthermore, the presence of the inner and outer rectangular grooves facilitates the installation of both the silicone thermal pad and the thermal block, and this area of ​​the side panel is enclosed.

[0013] Furthermore, the silicone thermal pad is flush with the inner wall of the side plate; the top and bottom of the U-shaped thermal base both have arc-shaped chamfers.

[0014] This makes it easier for the U-shaped heat sink to move downwards from the silicone heat pad and more easily to move upwards to contact the silicone heat pad.

[0015] Furthermore, a first fan unit and a second fan unit are installed at the mounting bracket, and the electrical mounting plate is located between the first fan unit and the second fan unit.

[0016] Furthermore, the two vertical limiting rods and two horizontal limiting rods of the limiting frame correspond one-to-one, and the corresponding vertical limiting rods and horizontal limiting rods are connected.

[0017] Furthermore, the two first abutting protrusions can respectively abut against the first hinge rod and the second hinge rod.

[0018] Furthermore, the two second abutting protrusions can respectively abut against the first hinge rod and the second hinge rod.

[0019] Furthermore, both first abutting protrusions and both second abutting protrusions have abutting arc surfaces.

[0020] Furthermore, the inner rectangular groove is located on the inner sidewall of the side plate, and the outer rectangular groove is located on the outer sidewall of the side plate.

The mounting frame also includes a vertical plate and two vertical rods, which are fixedly connected to the first, second, third, and fourth horizontal plates.

The cable fixing unit includes a sliding plate. The sliding plate has a horizontal groove that cooperates with the horizontal guide rail and a fixing bolt that cooperates with the threaded hole. The sliding plate has a rectangular through hole and multiple insertion holes. A clamping unit is installed at each insertion hole. The clamping unit includes an end cap connected to the sliding plate by a tension spring and a clamping rod connected to the end cap and inserted into the insertion hole.

[0023] The fixing bolts can adjust the distance between the sliding plate and the fixed vertical plate, thus enabling fine-tuning, and allowing the clamping rod to better clamp the fixed cable.

[0024] Furthermore, the cable corresponding to each functional module is abutted by the first clamping rod, passes over the connecting crossbar below, passes over the guide roller, and connects to a socket unit on the electrical mounting plate.

[0025] Furthermore, the end of the clamping rod has an abutting arc surface capable of abutting the cable.

[0026] Furthermore, the horizontal guide rail has four sections, and the threaded holes and fixing bolts each have four sections.

[0027] Furthermore, there are multiple first springs and multiple second springs.

[0028] Furthermore, the heat-conducting block has a plurality of first heat-conducting fins.

[0029] Furthermore, the U-shaped heat-conducting seat includes a top seat, a bottom seat, and a heat-conducting plate connecting the top seat and the bottom seat, wherein the heat-conducting plate has a plurality of second heat-conducting fins.

[0030] Furthermore, the fifth spring is connected to the closed end of the top slot, and the sixth spring is connected to the closed end of the bottom slot.

[0031] Furthermore, the base is fixedly connected to a bottom flange; the lifting seat includes an inverted U-shaped seat and two lifting blocks respectively fixed on both sides of the inverted U-shaped seat, the lifting blocks can move up and down along the lifting limit channel, and the lifting seat can abut against four limit crossbars and be supported by the four limit crossbars.

[0032] Furthermore, the multiple sockets at the sliding plate are divided into multiple first sockets and multiple second sockets. The multiple first sockets are located above the rectangular through hole and are distributed in a row with equal spacing, while the multiple second sockets are located below the rectangular through hole and are distributed in a row with equal spacing.

[0033] Furthermore, the first row of sockets and the second row of sockets are staggered.

[0034] This allows for the secure clamping and fixing of multiple cables.

[0035] Furthermore, the first maintenance door is installed on the panel, and the second maintenance door is installed on the back panel; the mounting bracket can be in a first state and a second state. In the first state, the lifting seat abuts against two limiting connecting blocks, two first abutting protrusions abut against the first hinge rod and the second hinge rod respectively, two second abutting protrusions abut against the first hinge rod and the second hinge rod respectively, and two U-shaped heat-conducting seats abut against two silicone heat-conducting pads respectively; in the second state, the first maintenance door is open, the lifting seat abuts against four limiting crossbars, and the mounting bracket faces the maintenance opening where the first maintenance door is located.

[0038] Furthermore, in the first state, the hinge positions of the first hinge rod and the second hinge rod protrude towards the back plate; in the second state, the hinge positions of the first hinge rod and the second hinge rod extend out of the maintenance opening corresponding to the first maintenance door.

[0039] Beneficial effects:

[0040] 1. The smart street light of this application has a lower risk of getting wet in rainy weather because the mounting bracket is located in a higher position inside the base when maintenance is not required and does not face the first maintenance door. Even if the first maintenance door is not sealed properly due to aging or improper operation, the risk of the electrical mounting plate getting wet is also low.

[0041] 2. In the smart street light of this application, the top, bottom and sides of the mounting bracket are buffered by springs when no maintenance is required. Therefore, when the light pole is subjected to a slight impact, the internal mounting bracket can be buffered, making the impact less severe.

[0042] 3. In the smart street light of this application, when the electrical mounting plate is in use, the first fan unit and the second fan unit can form a circulating airflow surrounding the electrical mounting plate, so that the heat of the electrical mounting plate is transferred to the U-shaped heat conduction seat and then transferred to the outside through heat conduction, avoiding direct convection with the outside air, thereby further preventing moisture.

[0063] Working Principle: The smart street light of this application has multiple functional modules, enabling monitoring of the surrounding environment, such as temperature, humidity, and air quality. It also provides video surveillance, information display, and audio broadcasting functions, and can wirelessly communicate with a remote control center. An electrical mounting plate is installed within the base, allowing for easy installation and maintenance by connecting the various functional modules and the electrical mounting plate via plug and socket units. The base has a first maintenance port and a second maintenance port; a first maintenance door closes the first maintenance port, and a second maintenance door closes the second maintenance port.

[0064] And as Figure 6 As shown, when maintenance is not required, the mounting bracket is in its first state. In this state, the two first abutting protrusions and the two second abutting protrusions limit the movement of the first and second hinge rods. The mounting bracket is supported by the lifting horizontal plate and the lifting support plate, and both the top and bottom ends are spring-buffered. The heat-conducting seats on both sides are also buffered by the fifth and sixth springs, thus protecting the mounting bracket. Even if the base is subjected to a slight impact, the impact on the mounting bracket is relatively small. Furthermore, under the action of the first and second fan units, a ring-shaped cooling airflow can be formed. This ring-shaped cooling airflow creates heat conduction between the mounting bracket and the two U-shaped heat-conducting seats, and the U-shaped heat-conducting seats transfer heat to the heat-conducting blocks, thereby transferring it to the outside environment.

[0065] When the mounting bracket requires maintenance, the first maintenance door can be opened, allowing the bracket to descend to face the first maintenance opening, facilitating maintenance of the electrical mounting plate. Furthermore, due to the structure of the cable fixing unit and guide rollers, sufficient cable slack is provided between the cable fixing unit and the electrical mounting plate, preventing cable pulling during bracket descent and avoiding cable tangling during bracket ascent, as the cables bypass the connecting crossbar and guide rollers below. The second maintenance door can also be opened for maintenance of the cable fixing unit as a whole; however, once the cable fixing unit is set up to secure each cable, it generally does not require special maintenance, therefore the second maintenance door is opened less frequently. Typically, the second maintenance door is opened less frequently than the first maintenance door.

[0066] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention without departing from the scope defined by the claims.
