Description

Technical Field

[0001] The present invention relates to the technical field of street lamps, and more specifically, to a street lamp pole and an LED intelligent street lamp based on the street lamp pole. Background Art

[0002] With the proposal of the concept of smart city, intelligent street lamps, as a new type of lighting equipment, have been applied in many occasions. Intelligent street lamps not only provide basic lighting functions, but also integrate advanced technologies to achieve intelligent management and multi-functional services, providing strong support for the sustainable development of the city.

[0003] Intelligent street lamps are equipped with many devices and require more frequent maintenance. However, the general street lamps are relatively high. When the street lamps need to be maintained, it is very inconvenient for maintenance personnel to work at a high position. Extra tools or equipment need to be set up to approach the lighting part of the street lamp, which not only increases the complexity and time cost of maintenance, but also may lead to additional equipment investment and cost expenditure. Moreover, working at a high altitude poses a great safety hazard to maintenance personnel. In addition, when traditional intelligent street lamps are designed and produced, the configuration of their functional modules is often fixed. This means that the functions of the street lamp are determined at the time of factory shipment and it is difficult to flexibly adjust according to the actual application scenarios and requirements. Summary of the Invention

[0004] The present invention aims to overcome the defects of the prior art and provides a street lamp pole and an LED intelligent street lamp based on the street lamp pole.

[0005] To achieve the above object, the present invention provides the following technical solution: A street lamp pole, comprising a lamp pole, two fixed seats and two bracket units. The fixed seat includes a fixed sleeve fixedly connected to the lamp pole, a fixed block fixedly connected to the fixed sleeve, and two limiting side plates fixed at the fixed block. There is a fixed block groove at the fixed block, and a fixed seat guide roller is installed in the fixed block groove; One of the bracket units is installed at each fixed seat. The bracket unit includes an installation part, two connecting plates fixedly connected to the installation part, two limiting blocks respectively fixedly connected to the two connecting plates, and a bracket guide roller installed between the two connecting plates. The ends of the two connecting plates of the bracket unit are both hinged to the fixed sleeve; The two fixed seats are distributed vertically, namely the upper fixed seat and the lower fixed seat. The fixed seat guide roller at the upper fixed seat is the upper fixed seat guide roller, and the fixed seat guide roller at the lower fixed seat is the lower fixed seat guide roller. The two bracket units are respectively the upper bracket unit and the lower bracket unit. The bracket guide roller at the upper bracket unit is the upper bracket guide roller, and the bracket guide roller at the lower bracket unit is the lower bracket guide roller. A fixed pulley is installed at the top of the lamp pole. The lamp pole has a side opening, and an electric winding device facing the side opening is installed inside the lamp pole. The electric winding device winds a pulling rope. The pulling rope passes through the lower fixed seat guide roller, the lower bracket guide roller, the fixed pulley and the upper bracket guide roller, and the end of the pulling rope is connected to the upper fixed seat guide roller.

[0006] Further, the bottom of the lamp pole has a bottom flange.

[0007] Further, the street lamp pole can be in an installation state and a maintenance state. In the installation state, the two limiting blocks of the upper bracket unit and the two limiting blocks of the lower bracket unit both abut against the lamp pole, the pulling rope is in a taut state, and the pulling rope presses against the lower fixed seat guide roller, the lower bracket guide roller and the upper bracket guide roller; In the maintenance state, the two connecting plates of the lower bracket unit both abut against the lower fixed seat and are both located between the two limiting side plates of the lower fixed seat, and the two connecting plates of the upper bracket unit both abut against the upper fixed seat and are both located between the two limiting side plates of the upper fixed seat, and the pulling rope is in a relaxed state.

[0008] In some embodiments, the fixed pulley has an anti-detachment unit for preventing the pulling rope from detaching from the fixed pulley.

[0009] For example, a plurality of connecting rods are connected between the two side plates of the fixed pulley. Thus, the pulling rope is prevented from detaching from the fixed pulley.

[0010] Further, in the installation state, the pulling rope passes through the lower fixed seat guide roller, the lower bracket guide roller, the fixed pulley and the upper bracket guide roller in sequence.

[0011] Further, the upper fixed seat guide roller has a semi-circular ring, and the end of the pulling rope is connected to the semi-circular ring.

[0012] Thus, it is convenient to connect the end of the pull rope.

[0013] Furthermore, there is a gap between the two limit blocks of the bracket unit.

[0014] Thus, the pull rope can pass through the gap.

[0015] Furthermore, the end of the installation part close to the bracket guide roller has an arc chamfer.

[0016] Thus, the friction between the pull rope and the arc chamfer will not damage the pull rope.

[0017] Furthermore, both sides of the installation part are provided with strip-shaped sliding grooves. A sliding plate unit is installed at the installation part. The sliding plate unit includes two sliding side plates and a mounting plate connected between the two sliding side plates. A strip-shaped slider matched with the strip-shaped sliding groove is fixed at the sliding side plate. The strip-shaped slider is connected with a pressing block through a spring. Both ends of the strip-shaped sliding groove are closed. A pressure sensor is installed at one end of the strip-shaped sliding groove close to the bracket guide roller. The sliding plate unit is also fixedly connected with a U-shaped frame. A U-shaped frame guide roller is installed at the U-shaped frame. The pull rope passes through the U-shaped frame guide rollers of the two sliding plate units.

[0018] Furthermore, in the installation state, both U-shaped frame guide rollers abut against the pull rope, and the springs at the two sliding plate units are both compressed; in the maintenance state, each strip-shaped slider abuts against the end of the strip-shaped sliding groove far from the pressure sensor.

[0019] Furthermore, the weight of the bracket unit is greater than or equal to 5 times the weight of the sliding plate unit.

[0020] Furthermore, a mounting frame is fixed at the mounting plate. The mounting frame has a plurality of strip-shaped through grooves. A mounting seat is installed at the mounting frame. The mounting seat includes a seat body, a screw rod fixedly connected with the seat body, and a nut matched with the screw rod. The screw rod passes through the strip-shaped through groove and is matched with the nut to fix the mounting seat at the mounting frame.

[0021] Furthermore, the mounting frame includes two end plates and a base plate connecting the two end plates. A plurality of strip-shaped through grooves are located at the base plate; the number of strip-shaped through grooves at each base plate is greater than or equal to 5.

[0022] Furthermore, two magnetic attraction units are fixed at the lamp post. Each magnetic attraction unit includes a connecting seat fixed to the lamp post and a permanent magnet fixed to the connecting seat. The U-shaped frame is made of iron material. The two magnetic attraction units are respectively an upper magnetic attraction unit and a lower magnetic attraction unit. In the installed state, the end of the U-shaped frame of the upper support unit abuts and attracts the permanent magnet of the upper magnetic attraction unit, and the end of the U-shaped frame of the lower support unit abuts and attracts the permanent magnet of the lower magnetic attraction unit.

[0023] This application also discloses an LED intelligent street lamp based on the above-mentioned street lamp post. An LED lighting unit is installed at the installation part, and at least one of a control box, a WIFI unit, a broadcast unit, a video monitoring unit, an air quality sensor unit, and a base station unit is installed at the seat body.

[0024] Furthermore, two mounting seats are installed on the mounting frame of the upper support unit, and two mounting seats are installed on the mounting frame of the lower support unit.

[0025] Furthermore, a broadcast unit and a video monitoring unit are respectively installed on the two mounting seats of the upper support unit; an air quality sensor unit and a control box are respectively installed on the two mounting seats of the lower support unit. A control unit and a wireless communication unit are installed in the control box, and the electric winding device is controlled by the control unit.

[0026] Furthermore, in the installed state, the control unit controls such that when the measured values of more than one of the multiple pressure sensors are less than or equal to the set threshold value, the wireless communication unit is controlled to send an alarm signal.

[0027] Thus, when the pressure sensor is less than the set threshold value, it indicates that there is no longer a tight abutment between the U-shaped frame roller and the pull rope, which means that there is a problem with the installation of the sliding plate unit, and thus an alarm is given to remind for maintenance.

[0028] Beneficial effects:

[0029] 1. The street lamp of this application has an installed state and a maintenance state. In the installed state, the street lamp can be used for lighting. In the maintenance state, the two support units can be rotated downward, and the sliding plate unit can be further lowered, which is convenient for maintenance.

[0030] 2. For the street lamp of this application, multiple mounting seats can be installed on the mounting frame, so that each functional module of the intelligent street lamp can be selectively installed according to actual needs, making the street lamp more flexible in use and meeting the use requirements of a smart city.

The sliding plate unit includes two sliding side plates 6.1 and a mounting plate 6.2 connected between the two sliding side plates 6.1. A strip-shaped slider 6.3 matching the strip-shaped sliding groove is fixed at the sliding side plate 6.1. The strip-shaped slider 6.3 is connected with a pressing block 6.5 through a spring 6.4. Both ends of the strip-shaped sliding groove are closed. A pressure sensor 3.6 is installed at one end of the strip-shaped sliding groove close to the support roller. The sliding plate unit is also fixedly connected with a U-shaped frame 6.6. A U-shaped frame roller 6.7 is installed at the U-shaped frame. The pull rope 5.1 passes through the U-shaped frame rollers 6.7 of the two sliding plate units; in the installation state, both U-shaped frame rollers abut against the pull rope 5.1, and the springs 6.4 at the two sliding plate units are compressed; in the maintenance state, each strip-shaped slider 6.3 abuts against the end of the strip-shaped sliding groove away from the pressure sensor. A mounting frame is fixed at the mounting plate 6.2. There are a plurality of strip-shaped through grooves at the mounting frame. A mounting seat is installed at the mounting frame. The mounting seat includes a seat body 8.1, a screw rod 8.2 fixedly connected with the seat body, and a nut 8.3 matching the screw rod. The screw rod passes through the strip-shaped through groove and is matched with the nut to fix the mounting seat at the mounting frame. The mounting frame includes two end plates 7.1 and a base plate 7.2 connecting the two end plates 7.1. A plurality of strip-shaped through grooves are located at the base plate; the number of strip-shaped through grooves at each base plate is greater than or equal to 5. Two magnetic attraction units are fixed at the lamp post. The magnetic attraction unit includes a connecting seat 9.1 fixed at the lamp post and a permanent magnet 9.2 fixed at the connecting seat. The U-shaped frame 6.6 is made of iron material; the two magnetic attraction units are respectively an upper magnetic attraction unit and a lower magnetic attraction unit. In the installation state, the end of the U-shaped frame of the upper support unit abuts against and attracts the permanent magnet of the upper magnetic attraction unit, and the end of the U-shaped frame of the lower support unit abuts against and attracts the permanent magnet of the lower magnetic attraction unit.

[0046] Two mounting seats are installed at the mounting frame of the upper support unit, and two mounting seats are installed at the mounting frame of the lower support unit. A broadcasting unit 8.4 and a video monitoring unit 8.5 are respectively installed at the two mounting seats of the upper support unit; an air quality sensor unit 8.6 and a control box 8.7 are respectively installed at the two mounting seats of the lower support unit. A control unit and a wireless communication unit are installed in the control box, and the electric winding device 5 is controlled by the control unit.

[0047] Working principle: The street lamp of the present application has an installation state and a maintenance state. In the installation state, as Figure 1As shown, the street lamp can be used for normal lighting. And one or more mounting seats can be selectively installed at the top of the bracket unit, so that the mounting seats can be used to install units such as control boxes, WIFI units, broadcast units, video surveillance units, air quality sensor units, base station units, etc., so as to achieve multi-functionality and meet the use of smart cities. The mounting seat is fixed by matching the screw and nut through the strip-shaped through groove, and the use and installation of the functional unit are very flexible. At this time, due to the tension of the pull rope, the pull rope pulls the U-shaped frame closer to the lamp post, thereby compressing the spring and enabling the pressure sensor to have a measured value. The control unit controls that when the measured values of more than one of the multiple pressure sensors are less than or equal to the set threshold, the wireless communication unit is controlled to send an alarm signal. When the pressure sensor is less than the set threshold, it means that there is no longer a tight contact between the U-shaped frame roller and the pull rope, which indicates that there is a problem with the installation of the sliding plate unit or the tension of the pull rope, so an alarm is given to remind maintenance. And in the normal installation state, due to the attraction and abutment fixation of the permanent magnet and the U-shaped frame, the position of the sliding plate unit can be further limited, thereby preventing the sliding plate unit from shaking due to the wind in nature.

[0048] When maintenance is required for the LED lighting unit or the above-mentioned functional unit, the control unit controls the electric winding device to slowly release the rope, so that the bracket unit will slowly descend due to its own gravity and descend to Figure 2 the position described. Continuing to release the rope, the sliding plate unit will slide down due to its own gravity, so as to reach Figure 3 the position shown. Thus, since the functional unit descends to a lower position, it is convenient for maintenance, greatly reducing the work difficulty and risk of maintenance personnel. After the maintenance is completed, by winding the rope of the electric winding device, the street lamp can be restored to Figure 1 the state shown.

[0049] Although the present invention has been illustrated and described with respect to the preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention as long as they do not exceed the scope defined by the claims of the present invention.
