Description

Technical Field

[0001] The present invention belongs to the technical field of street lamps, and in particular relates to a multifunctional energy-saving smart lamp pole for a digital city. Background Art

[0002] With the rapid development of digital city construction, smart lamp poles, as an important part of urban infrastructure, have gradually attracted widespread attention. Smart lamp poles integrate multiple functions such as lighting, monitoring, communication, and environmental monitoring, which improves the level of intelligent urban management. For example, a multifunctional smart lamp pole disclosed in a Chinese patent document with publication number CN113944901A includes a first mounting member, and the first mounting member directly contacts the mounting wall; the smart lamp pole can conveniently adjust the length and installation angle of the lamp pole, is easy to adjust, and has good use effect.

[0003] However, when the above-mentioned lamp poles are applied in digital cities, the following technical problems still exist:

[0004] In the application of smart light poles in digital cities, the humidity will change with the changing seasons and weather, and the existing smart light poles cannot adjust the lighting intensity in real time according to the humidity. In high humidity environments such as rainy days or spring and summer, higher humidity will increase the moisture in the air, resulting in increased light scattering and refraction, which in turn reduces the lighting effect of the smart light poles. In low humidity environments such as sunny days or autumn and winter, the lighting effect is guaranteed, but the lighting intensity cannot be reduced to avoid unnecessary energy waste.

[0005] In addition, since smart light poles need to have vents to dissipate heat from internal electrical components, there is air flow between the outside air and the air inside the smart light poles. Therefore, changes in ambient humidity can easily affect the normal operation of smart light poles: when the humidity is high, it is easy to cause rust and corrosion to the electrical components and connecting parts inside the smart light poles. When the humidity is low, it is easy to cause static electricity accumulation, thereby interfering with the normal operation of the electronic equipment inside the smart light poles.

[0006] Therefore, there is an urgent need for a digital city multifunctional energy-saving smart lamp pole that can adjust the lighting intensity and the humidity inside the lamp pole in real time according to the humidity of the working environment. Summary of the invention

[0019] Compared with existing technologies, the advantages of this digital city multifunctional energy-saving smart lamp pole are:

[0020] 1. The present invention sets a brightness adjustment mechanism. In a high humidity environment such as rainy days or spring and summer, the humidity of the working environment is high, which causes the rubber spring to absorb moisture, thereby reducing its hardness and elastic modulus, reducing the elastic force of the rubber spring, and the lifting plate moves downward, driving the slider to slide on the resistance rod, so that the resistance value of the circuit where the lighting lamp is located is reduced, and the current is increased, thereby increasing the light intensity and the brightness to improve the clarity of vision and the lighting effect. In a low humidity environment such as sunny days or autumn and winter, the rubber spring will lose some moisture, thereby increasing the hardness and elastic modulus, increasing the elastic force of the rubber spring, reducing the current of the circuit where the lighting lamp is located, and reducing the light intensity. Under the premise of ensuring the lighting effect, the lighting intensity is reduced to avoid unnecessary energy waste.

[0021] 2. The present invention sets a humidity regulating component. When the humidity is high, the downward movement of the lifting plate will drive the hydraulic telescopic rod to be in an extended state, thereby allowing more hydraulic oil in the control frame to enter the hydraulic telescopic rod. The reduction of hydraulic oil in the control frame will cause the piston plate to move to the right in the control frame, thereby reducing the compression degree of the piston plate on the first spring and reducing the deformation of the first spring. Therefore, the elastic force of the first spring can be reduced, and the pressure between the active friction plate and the driven friction plate is reduced. The friction force is reduced, and the torque is reduced. When the power is fixed, the reduced torque will cause the speed to increase. Therefore, when the humidity is high, the speed of the transmission rod and the axial flow fan blades can be increased, and the air circulation can be increased to reduce the humidity, so as to prevent the high humidity environment from causing rust or corrosion of the electrical components and connecting parts inside the lamp pole, affecting the performance and safety. On the contrary, when the humidity is low, the hydraulic telescopic rod is in a compressed state, thereby reducing ventilation, maintaining moisture, and preventing the low humidity environment from causing static electricity accumulation, interfering with the normal operation of the electronic equipment inside the lamp pole body, and effectively preventing humidity changes from affecting the normal operation of the smart lamp pole.

[0022] 3. The present invention sets an auxiliary component. When the humidity of the external environment is high, the centrifugal force drives the slider to move to the outer position of the centrifugal chamber, so that the dehumidifier starts to work, to avoid the effect of reducing humidity being compromised when the air circulation is accelerated due to excessive humidity. When the humidity of the external environment is low, the slider is moved to the inner position of the centrifugal chamber under the elastic force of the second spring. At this time, the first electric contact block contacts the second electric contact block, so that the humidifier starts to work, and the humidity inside the lamp pole is increased, thereby ensuring the humidity regulation effect inside the lamp pole, and further ensuring the operation of the smart lamp pole.

DETAILED DESCRIPTION

[0029] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0030] Example: Refer to Figures 1 to 5 , a digital city multifunctional energy-saving smart lamp pole, comprising:

[0031] A lamp pole body 1, a lamp board 11 is fixedly connected to the top of the lamp pole body 1, a lighting lamp 12 is arranged at the lower end of the lamp board 11, and a lamp pole seat 13 is fixedly connected to the lower end of the lamp pole body 1;

[0032] Among them, an integrated unit 3 is arranged on the lamp pole seat 13, and the integrated unit 3 includes components such as a camera and an air quality sensor (not marked in the figure). The integrated unit 3 is connected with the city management system, the traffic control system, etc. through the Internet of Things. Through the integrated unit 3, environmental parameters, traffic flow and urban safety conditions can be monitored in real time. Through data collection and analysis, it helps city managers optimize resource allocation, improve public service efficiency and enhance urban safety.

[0033] The brightness adjustment mechanism 2 is used to adjust the light intensity of the lighting lamp 12 according to the ambient humidity. The brightness adjustment mechanism 2 includes a control box 21 fixedly connected to the side wall of the lamp pole body 1. A through hole 22 is opened on the front and rear side walls of the control box 21. A lifting plate 23 is airtightly slidably connected inside the control box 21. The space below the lifting plate 23 in the control box 21 is connected to the outside through the through hole 22. A rubber spring 24 is provided between the lower wall of the lifting plate 23 and the inner bottom wall of the control box 21. An L-shaped rod 25 is fixedly connected to the upper end of the lifting plate 23. A resistor box 26 is fixedly connected to the outer wall of the control box 21. A resistor rod 27 is fixedly connected to the inside of the resistor box 26. A slide 28 is vertically slidably connected to the resistor rod 27. Two connecting rods 29 are fixedly connected between the slide 28 and the L-shaped rod 25. The lighting lamp 12 is connected in series with the power supply device inside the lamp pole body 1 through the resistor rod 27 and the slide 28.

[0034] Among them, polymer films, ceramic materials, rubber materials, and some fibers and composite materials are sensitive to humidity. The performance of these materials will change with changes in humidity. In the present application, the rubber spring 24 is made of a humidity-sensitive rubber material, and the elastic force of the rubber spring 24 changes with changes in humidity.

[0035] In view of the problem in the prior art that the humidity changes with the changing seasons and weather, and the existing smart lamp pole cannot adjust the lighting intensity in real time according to the humidity, the present invention sets a brightness adjustment mechanism 2 to automatically adjust the light intensity of the lamp pole according to the humidity of the working environment, which not only avoids safety hazards but also plays an energy-saving effect. The specific adjustment of the light intensity of the lamp pole is as follows:

[0036] In a high humidity environment such as rainy days or spring and summer, the humidity of the working environment is high, causing the rubber spring 24 to absorb moisture, thereby reducing its hardness and elastic modulus, so that the elastic force of the rubber spring 24 is reduced, and the lifting plate 23 moves downward, driving the slide 28 to slide on the resistance rod 27 through the L-shaped rod 25 and the connecting rod 29, so that the resistance value of the circuit where the lighting lamp 12 is located is reduced, and the current is increased, thereby increasing the light intensity, increasing the brightness to improve the clarity of vision, and improving the lighting effect;

[0037] On sunny days or in low humidity environments such as autumn and winter, the rubber spring 24 will lose some moisture, thereby increasing the hardness and elastic modulus, increasing the elastic force of the rubber spring 24, and the lifting plate 23 moves upward, driving the slider 28 to slide in the opposite direction on the resistance rod 27. The current in the circuit where the lighting lamp 12 is located is reduced, reducing the light intensity. Under the premise of ensuring the lighting effect, the lighting intensity is reduced to avoid unnecessary energy waste.

[0038] It also includes a ventilation mechanism 4 for dissipating heat for the electrical components inside the lamp pole body 1. The ventilation mechanism 4 includes a ventilation duct 41 arranged at the top of the lamp pole body 1 and connected to the inside of the lamp pole body 1. The side wall of the lamp pole body 1 is located below the control box 21 and is connected to two air inlets 42. The upper end of the ventilation duct 41 is fixedly connected to an exhaust duct 43. Specifically, a water filter membrane is provided inside the exhaust duct 43 to prevent rainwater from entering the inside of the lamp pole body 1 on rainy days and causing the electrical components inside the lamp pole body 1 to be damaged by moisture. The inside of the exhaust duct 43 is rotatably connected to a transmission rod 44 through a mounting plate. A plurality of axial flow fan blades 45 are fixedly connected to the transmission rod 44. A humidity adjustment component 5 for adjusting the humidity inside the lamp pole body 1 is provided on the outer wall of the exhaust duct 43.

[0039] It is worth mentioning that through the ventilation mechanism 4, when the smart lamp pole is in use, the transmission rod 44 and the axial flow fan blades 45 can be rotated to drive the air inside the lamp pole body 1 to circulate, and the air inside the lamp pole body 1 first enters the lamp pole body 1 through the two air inlets 42 arranged at the bottom, and then the axial flow fan blades 45 rotate to discharge the air inside the lamp pole body 1 from the top to the outside of the lamp pole body 1 to dissipate heat for the internal electrical components. Filters can be set at the air inlet 42 and the ventilation duct 41 to filter dust in the air to prevent dust from entering the lamp pole body 1 and affecting the operation of the electrical components inside the lamp pole body 1.

[0040] The humidity regulating assembly 5 comprises a supporting plate 51 fixedly connected to the outer wall of the exhaust duct 43, a slide plate 52 is linearly slidably connected to the upper part of the supporting plate 51, a motor 53 is fixedly connected to the upper end of the slide plate 52, a driving rod 54 is fixedly connected to the output end of the motor 53, an active friction disc 55 is fixedly connected to the top end of the driving rod 54, a driven friction disc 56 which is in contact with the active friction disc 55 is fixedly connected to the top end of the transmission rod 44, a control frame 57 is fixedly connected to the upper end of the supporting plate 51, a piston plate 58 is sealingly slidably connected to the inner wall of the control frame 57, a push rod 59 is fixedly connected to the outer wall of the motor 53, a first spring 510 is provided between the push rod 59 and the piston plate 58, a hydraulic telescopic rod 511 is fixedly connected to the upper end of the lifting plate 23, a liquid infusion tube 512 is connected between the interior of the hydraulic telescopic rod 511 and the interior of the control frame 57, and an auxiliary component 6 for assisting in humidity regulation is provided inside the driven friction disc 56.

[0041] A liquid storage space is formed between a side wall of the piston plate 58 away from the first spring 510 and the inner wall of the control frame 57 , and the interior of the hydraulic telescopic rod 511 , the infusion tube 512 and the liquid storage space are filled with hydraulic oil.

[0042] In view of the problem that the change of ambient humidity in the prior art can easily affect the normal operation of the smart lamp pole: when the humidity is high, it is easy to cause rust and corrosion to the electrical components and connecting parts inside the smart lamp pole; when the humidity is low, it is easy to cause static electricity accumulation, thereby interfering with the normal operation of the electronic equipment inside the smart lamp pole. The present invention can adjust the humidity inside the lamp pole body 1 according to the change of ambient humidity by setting a humidity adjustment component 5. The specific adjustment process is as follows:

[0043] When the humidity is high, the downward movement of the lifting plate 23 will drive the hydraulic telescopic rod 511 to be in an extended state, thereby allowing more hydraulic oil in the control frame 57 to enter the hydraulic telescopic rod 511. The reduction of hydraulic oil in the control frame 57 will cause the piston plate 58 to move to the right in the control frame 57, thereby reducing the compression degree of the piston plate 58 on the first spring 510, and reducing the deformation of the first spring 510. Therefore, the elastic force of the first spring 510 can be reduced, reducing the pressure between the active friction plate 55 and the driven friction plate 56, reducing the friction force, and reducing the torque. The reasons are as follows:

[0044] Friction torque: Friction torque is determined by the friction force and the radius of the friction contact surface (or the distance from the axis). The friction torque (Mf) can be expressed as follows:

[0045] Mf=F*r

[0046] Among them, F is the friction force, r is the distance from the point of friction force to the axis of rotation;

[0047] When the power is fixed, the torque reduction will lead to an increase in speed for the following reasons:

[0048] Power (P) can be expressed as the product of torque (T) and speed (N):

[0049] P=T×ω

[0050] Where ω is the angular velocity (usually converted to RPM), which can be expressed as:

[0051]

[0052] Therefore, the power can be expressed as:

[0053]

[0054] In this case, if the power is fixed, when the torque increases, the speed will decrease, and conversely, when the torque decreases, the speed will increase;

[0055] Therefore, when the humidity is high, the rotation speed of the transmission rod 44 and the axial flow fan blades 45 can be increased to increase air circulation to reduce humidity, thereby preventing the high humidity environment from causing rust or corrosion of the electrical components and connecting parts inside the lamp pole, thereby affecting performance and safety;

[0056] When the humidity is low, the hydraulic telescopic rod 511 is in a compressed state, and the piston plate 58 moves to the left in the control frame 57. The deformation of the first spring 510 increases, and the elastic force increases, thereby increasing the friction between the active friction disk 55 and the driven friction disk 56, and increasing the torque. Therefore, when the humidity is low, the rotation speed of the axial flow fan blade 45 is reduced, ventilation is reduced, moisture is maintained, and static electricity accumulation caused by a low humidity environment is prevented, which interferes with the normal operation of the electronic equipment inside the lamp pole body, and effectively prevents humidity changes from affecting the normal operation of the smart lamp pole.

[0057] The auxiliary component 6 includes a centrifugal chamber 61 opened inside the driven friction disk 56, and a slider 62 is slidably connected inside the centrifugal chamber 61. A second spring 63 is provided between a side wall of the slider 62 and the inner wall of the centrifugal chamber 61, and a first electric contact 64 is provided at the upper end of the slider 62. A second electric contact 65 and a third electric contact 66 that cooperate with the first electric contact 64 are respectively provided on the inner top walls on both sides of the centrifugal chamber 61. A humidifier controlled by the second electric contact 65 and a dehumidifier controlled by the third electric contact 66 are provided inside the lamp pole body 1.

[0058] The humidifier is connected in series with the power supply device inside the lamp pole body 1 through the first electric contact block 64 and the second electric contact block 65 , and the dehumidifier is connected in series with the power supply device inside the lamp pole body 1 through the first electric contact block 64 and the third electric contact block 66 .

[0059] In addition, in order to ensure the effect of regulating the humidity inside the lamp pole body 1, the present invention sets an auxiliary component. When the humidity of the external environment is high, it is necessary to increase the rotation speed of the axial flow fan blades 45 to increase the air flow. At this time, the slider 62 is driven by the action of centrifugal force to move to the outer position of the centrifugal chamber 61, and further through the contact between the first electric contact block 64 and the third electric contact block 66, the dehumidifier starts to work to avoid the effect of reducing humidity when the air circulation is accelerated due to excessive humidity. When the humidity of the external environment is low, the rotation speed of the axial flow fan blades 45 is reduced to maintain moisture. At this time, the reduction in centrifugal force will cause the slider 62 to move to the inner position of the centrifugal chamber 61 under the elastic force of the second spring 63. At this time, the first electric contact block 64 and the second electric contact block 65 are in contact, so that the humidifier starts to work, which increases the humidity inside the lamp pole body 1, ensures the effect of regulating the humidity inside the lamp pole body 1, and further guarantees the operation of the smart lamp pole.

[0060] The present invention can be explained by the following operation mode:

[0061] In rainy days or high humidity environments such as spring and summer, the humidity of the working environment is high, causing the rubber spring 24 to absorb moisture, thereby reducing its hardness and elastic modulus, reducing the elastic force of the rubber spring 24, and the lifting plate 23 moves downward, driving the slide 28 to slide on the resistance rod 27 through the L-shaped rod 25 and the connecting rod 29, so that the resistance value of the circuit where the lighting lamp 12 is located is reduced, and the current is increased, thereby increasing the light intensity, increasing the brightness to improve the clarity of vision, and improving the lighting effect. At the same time, the downward movement of the lifting plate 23 will drive the hydraulic telescopic rod 511 to be in an extended state, thereby making the hydraulic oil in the control frame 57 more Entering the hydraulic telescopic rod 511, the reduction of hydraulic oil in the control frame 57 will cause the piston plate 58 to move to the right in the control frame 57, thereby reducing the compression degree of the piston plate 58 on the first spring 510, and reducing the deformation of the first spring 510. Therefore, the elastic force of the first spring 510 can be reduced, reducing the pressure between the active friction plate 55 and the driven friction plate 56, increasing the torque, increasing the rotation speed of the transmission rod 44 and the axial flow fan blade 45 when the humidity is high, and increasing air circulation to reduce humidity, so as to prevent the electrical components and connecting parts inside the lamp pole from rusting or corroding due to the high humidity environment;

[0062] In a low humidity environment such as a sunny day or in autumn and winter, the rubber spring 24 will lose some moisture, thereby increasing the hardness and elastic modulus, increasing the elastic force of the rubber spring 24, and moving the lifting plate 23 upward, driving the slider 28 to slide in the opposite direction on the resistor rod 27. The current in the circuit where the lighting lamp 12 is located is reduced, reducing the light intensity. Under the premise of ensuring the lighting effect, the lighting intensity is reduced to avoid unnecessary energy waste. At the same time, the hydraulic telescopic rod 511 is in a compressed state, and the piston plate 58 moves to the left in the control frame 57. The deformation of the first spring 510 increases, and the elastic force increases, thereby increasing the friction between the active friction disk 55 and the driven friction disk 56, and increasing the torque, thereby reducing the rotation speed of the axial flow fan blade 45 when the humidity is low, reducing ventilation, maintaining moisture, and preventing static electricity accumulation caused by a low humidity environment, which interferes with the normal operation of the electronic equipment inside the lamp pole body.

[0063] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
