Description
Technical Field
The invention relates to the technical field of screens, in particular to a lamp post display screen for intelligently transforming a common street lamp.
Background
In 2019, with the advance of 5G micro base stations, the concept of the smart city is gradually popularized, the smart lamp posts are used as a representative product of the concept of the smart city, governments in various places are issued with policy plans to support the industrial development, and a batch of smart lamp post projects are built and put into use. The wisdom lamp pole not only has the illumination function in urban road construction, has convenient multi-functional such as charging, warning help seeking, video monitoring, information issuing, advertisement interaction, public wiFi, voice broadcast moreover, has greatly made things convenient for citizen's use.
The biggest difference between the intelligent street lamp and the common street lamp is that the intelligent street lamp is different from the common street lamp in functions and display screens, and due to the reason, the lamp post display screens and the intelligent street lamp are bound together. Can say that, beat the wisdom street lamp of lamp pole display screen and let management and operation become more convenient, the benefit also is the aggregate stone and increases. From the advertiser's perspective, having had the joining of lamp pole display screen, a novel, efficient advertisement input mode is just on the eye, and this kind has high-definition video dynamic picture and image, passes through wireless network control to customer's advertisement content, and the demonstration form that the long-range synchronous update is accurate to express out without mistake is favored by the advertiser.
However, the existing current situation of China is that street lamps in most areas are still only common street lamps, and compared with the street lamps in the whole country, the intelligent street lamps are still only a small part. For the vast majority of areas with ordinary street lights, it is obviously not advisable to replace all ordinary street lights with intelligent street lights, both from a financial and an engineering standpoint. Therefore, as a replacement scheme, the original common street lamp is subjected to 'intelligent' modification, so that the method has considerable feasibility.
As the most important component of the intelligent street lamp, namely the lamp post display screen, how to efficiently and inexpensively modify the intelligent street lamp for the common street lamp becomes the problem which needs to be solved urgently at present.
Disclosure of Invention
In order to realize the purpose of using a lamp post display screen for the intelligent transformation of a common street lamp with high efficiency and low cost, the invention provides a lamp post display screen for the intelligent transformation of a common street lamp, and the specific technical scheme is as follows:
the utility model provides a lamp pole display screen that is used for ordinary street lamp "intellectuality" to reform transform, comprises lamp pole display screen and the photoelectricity case that holds integrated circuit and the wiFi equipment of setting on the photoelectricity case.
The photoelectric box can be directly fixed on the existing common street lamp post through the positioning hoop, the structure of the original street lamp is not required to be changed, the installation process is convenient and fast, and the installation can be completed without professionals.
The lamp post display screen comprises a hollow display screen frame, the display screen frame is connected to the street lamp post through a positioning hoop, and the inner cavity of the display screen frame is rotatably connected with the LED lamp screen through a rotating shaft; the lower end of the LED lamp screen is connected with the rotary connector through a rotating shaft, and the upper end of the LED lamp screen is connected with the homing device through a rotating shaft.
Different from the display screen on the smart lamp pole on the market, the lamp pole display screen designed by the invention is a rotating structure capable of automatically returning. The rotating structure with the non-rigid connection enables the lamp pole display screen to have good wind resistance, the lamp pole display screen can be automatically rotated by blowing the strong wind in typhoon weather, the windward area is reduced, and the lamp pole display screen is prevented from being damaged by the strong wind.
Furthermore, the rotary connector is wrapped at the bottom end of the display screen frame and consists of a connecting female seat and a connecting male head; the top surface of the connecting female seat is concentrically provided with a contact ring, and the bottom surface of the connecting sub-head is provided with a contact point corresponding to the position of the contact ring.
The contact ring and the contact point are made of copper. When the connecting female base and the connecting male head are closed together, the contact ring and the contact point are in contact with each other, so that the circuit of the LED lamp screen is communicated. When the LED lamp screen rotates, the connecting sub-head rotates relative to the connecting female base, but the contact ring and the contact point are always in a contact state, so that a circuit of the LED lamp screen cannot be interrupted due to the rotation of the position of the circuit.
Furthermore, the homing device is composed of a rotating rod connected with the LED lamp screen through a rotating shaft and a positioning rod connected with the street lamp pole through a positioning hoop.
The invention is arranged on the original common street lamp post by using the positioning hoop, and the destructive refitting such as drilling and the like is not needed for the original street lamp post, so the acid resistance, water resistance and wind resistance of the original common street lamp are not reduced. The use of the positioning hoop can not only not destroy the structure of the original common street lamp, but also greatly reduce the working difficulty of the new equipment, reduce the working strength of the installation personnel and shorten the transformation period of the common street lamp.
Furthermore, the permanent magnets are arranged at the corresponding positions of the two ends of the rotating rod and the positioning rod, the rotating rod and the positioning rod can be always kept in parallel by the mutual attraction between the permanent magnets, and the rotating rod is connected with the LED lamp screen through the rotating shaft, so that the LED lamp screen can be automatically reset.
Furthermore, the horizontal distance between the rotating rod and the display screen frame is 15-20cm, and the distance between the rotating rod and the display screen frame is kept to avoid electromagnetic interference of the permanent magnet on the LED lamp screen, so that the LED lamp screen is snowy and white. According to the test, when the horizontal distance between the rotating rod and the display screen frame is larger than 15cm, the electromagnetic interference phenomenon can be effectively avoided.
Further, the rotating rod is made of an insulating material. When the permanent magnets at the two ends of the rotating rod rotate in the magnetic fields of the permanent magnets at the two ends of the positioning rod, current can be generated, in order to avoid the interference effect of the current on the LED display screen, the rotating rod is made of insulating materials, and the magnetic current can be effectively blocked.
Further, unlike coastal areas, the frequency of typhoon and hurricane weather in inland areas is very low, so that the wind speed facing the lamp post display screen is usually low in normal use, and a magnetic homing device with a more complicated structure is not needed, and a torsion spring is used for replacing the magnetic homing device. Although the torsion spring is used as the homing device, the limitation of the maximum rotation angle exists, the torsion spring is preferably used as the homing device when the ordinary lamp pole in the inland area is transformed intelligently because the inland area rarely has strong wind weather and the manufacturing cost and the installation cost of the torsion spring are far lower than those of the magnetic homing device.
Furthermore, the locating hoop is an annular metal hoop, a circle of rubber gasket is arranged on the inner wall of the locating hoop, a fixing head used for tightening the locating hoop is arranged on one side of the outer wall, and a connecting port is arranged on one side, opposite to the fixing head, of the outer wall of the locating hoop.
When the lamp pole display screen is installed to needs, need not to drill the lamp pole of ordinary street lamp, only need open the location hoop, the card is on the lamp pole of ordinary street lamp, because of the location hoop inner wall is provided with the rubber pad, consequently along with the tightening of bolt on the fixed head, the location hoop can firmly grasp the lamp pole, provides the fixed point for the installation of lamp pole display screen.
Further, as an alternative to the positioning collar, the positioning collar is a square ferrule. In some areas of China, the style of the street lamp post is not a constant cylinder, and a prism-shaped lamp post also exists.
The working principle of the invention is as follows:
1) when the wind speed in the external environment is increased but the typhoon degree is not reached, the LED lamp screen rotates by a certain angle under the action of wind power, then gradually returns due to the restoring force provided by the magnetic force of the permanent magnet, and finally, when the external wind speed is stable, the LED lamp screen is still in the display screen frame.
2) When the wind speed in the external environment reaches the typhoon degree, powerful wind power can make LED lamp screen take place 360 continuous rotations in the display frame, and LED lamp screen is through rotating the pressure of release wind-force on the windward side, avoids the strong wind directly to blow bad lamp pole display screen. When external wind power is weakened, the LED lamp screen is finally stabilized in the display screen frame under the restoring force provided by the permanent magnet.
Compared with the existing intelligent transformation scheme of the common street lamp, the invention has the beneficial effects that:
1) the lamp post display screen is of a rotatable structure, and can automatically deflect and adjust the angle when facing strong wind weather, so that the windward area is reduced, the acting force of wind power on the lamp post display screen is reduced, the damage of the lamp post display screen caused by strong wind blowing is avoided, and the service life of equipment is greatly prolonged.
2) In the process of realizing the intellectualization of the street lamp, the old common street lamp does not need to be dismantled, the old street lamp can be directly reformed, and the municipal expenditure is greatly reduced.
3) When the old common street lamp is reformed, the destructive reforming such as drilling and the like on the original street lamp post is not needed, so that the acid resistance, water resistance and wind resistance of the original common street lamp are not reduced. And greatly reduced the installation degree of difficulty, alleviateed installer's working strength, shortened ordinary street lamp's transformation cycle.

Detailed Description
To further illustrate the manner in which the present invention is made and the effects achieved, the following description of the present invention will be made in detail and completely with reference to the accompanying drawings.
Example one
As shown in fig. 1, a lamp post display screen for "intelligent" modification of a common street lamp is composed of a lamp post display screen 1, a photoelectric box 2 for accommodating an integrated circuit, and WiFi equipment 3 arranged on the photoelectric box 2.
The photoelectric box 2 can be directly fixed on the existing ordinary street lamp pole through the positioning hoop 16, the structure of the original street lamp is not required to be changed, the installation process is convenient and fast, and the installation can be completed without professionals.
As shown in fig. 2, the lamp post display screen 1 includes a hollow display screen frame 11, the display screen frame 11 is connected to the street lamp post 4 through a positioning hoop 16, and an inner cavity of the display screen frame 11 is rotatably connected to the LED lamp screen 12 through a rotating shaft 14; the lower end of the LED lamp screen 12 is connected with a rotary connector 13 through a rotating shaft 14, and the upper end is connected with a homing device 15 through the rotating shaft 14.
Different from the display screen on the smart lamp pole on the market, the lamp pole display screen 1 designed by the invention is a rotating structure capable of automatically returning. The rotating structure with the non-rigid connection enables the lamp pole display screen 1 to have good wind resistance, and the lamp pole display screen can rotate by itself by blowing the strong wind in typhoon weather, so that the windward area is reduced, and the lamp pole display screen is prevented from being damaged by the strong wind.
As shown in fig. 5 and 6, the rotary connector 13 is wrapped at the bottom end of the display screen frame 11 and is composed of a female connector 131 and a male connector 132; the top surface of the female connector 131 is concentrically provided with a contact ring 1311, and the bottom surface of the male connector 132 is provided with a contact point 1321 corresponding to the position of the contact ring 1311.
The contact ring 1311 and the contact point 1321 are made of copper. When the female connector 131 and the male connector 132 are closed, the contact ring 1311 and the contact point 1321 contact each other, so that the circuit of the LED panel 12 is connected. When the LED panel 12 rotates, the connector sub-head 132 rotates relative to the connector female socket 131, but since the contact ring 1311 and the contact point 1321 are always in a contact state, the circuit of the LED panel 12 is not interrupted due to the rotation of the position.
As shown in fig. 2, the homing device 15 is composed of a rotation rod 151 connected to the LED panel 12 through the rotation shaft 14 and a positioning rod 152 connected to the light pole 4 through the positioning hoop 16.
The invention is arranged on the original common street lamp pole by using the positioning hoop 16, and the destructive refitting such as drilling and the like is not needed for the original street lamp pole, so the acid resistance, water resistance and wind resistance of the original common street lamp are not reduced. The positioning hoop 16 is used, so that the structure of the original common street lamp is not damaged, the working difficulty of new equipment is greatly reduced, the working strength of installation personnel is reduced, and the modification period of the common street lamp is shortened.
The permanent magnets 153 are arranged at the corresponding positions of the two ends of the rotating rod 151 and the positioning rod 152, the rotating rod 151 and the positioning rod 152 can be always kept at the parallel position by the mutual attraction between the permanent magnets 153, and the rotating rod 151 is connected with the LED lamp screen 12 through the rotating shaft 14, so that the LED lamp screen 12 can be automatically returned.
The horizontal distance between the rotating rod 151 and the display screen frame 11 is 15cm, and the distance between the rotating rod 151 and the display screen frame 11 is kept to avoid electromagnetic interference of the permanent magnet 153 on the LED lamp screen 12, so that the LED lamp screen 12 is snow-white. According to the test, when the horizontal distance between the rotating rod 151 and the display screen frame 11 is larger than 15cm, the electromagnetic interference phenomenon can be effectively avoided.
The rotation rod 151 is made of an insulating material. When the permanent magnet 153 at both ends of the rotating rod 151 rotates in the magnetic field of the permanent magnet 153 at both ends of the positioning rod 152, current can be generated, and in order to avoid the interference effect of the current on the LED display screen, the rotating rod 151 is made of an insulating material, so that the magnetic current can be effectively blocked.
As shown in fig. 7, the positioning hoop 16 is an annular metal hoop, and a ring of rubber gasket 161 is disposed on the inner wall thereof, and a fixing head 162 for tightening the positioning hoop 16 is disposed on one side of the outer wall, and a connection port is disposed on the side of the outer wall of the positioning hoop 16 opposite to the fixing head 162.
When the lamp pole display screen 1 needs to be installed, drilling is not needed to be carried out on the lamp pole of the common street lamp, the positioning hoop 16 is only needed to be opened and clamped on the lamp pole of the common street lamp, and the rubber pad 161 is arranged on the inner wall of the positioning hoop 16, so that the positioning hoop 16 can firmly grasp the lamp pole along with the tightening of the bolt on the fixing head 162, and a fixing point is provided for the installation of the lamp pole display screen 1.
Example two
Example two is identical to example one except that:
as an alternative to the homing device 15, as shown in fig. 3, the homing device 15 is formed by a torsion spring 154 disposed inside the upper end of the display panel frame 11 and sleeved on the rotation shaft 14.
Unlike coastal areas, inland areas have very low typhoon and hurricane weather frequency, so that the lamp post display screen 1 usually faces a smaller wind speed in use, and therefore, a magnetic homing device with a more complicated structure is not required to be used, and the torsion spring 154 is used for replacing the magnetic homing device. Although the torsion spring 154 is used as the homing device, there is a limitation on the maximum rotation angle, but because the inland area rarely has strong wind weather, and the manufacturing cost and the installation cost of the torsion spring 154 are far lower than those of the magnetic homing device, the torsion spring 154 is preferably used as the homing device when the ordinary lamp pole in the inland area is transformed in an intelligent way.
EXAMPLE III
Example three and example one the same except for the following differences:
as an alternative to the positioning collar 16, as shown in fig. 8, the positioning collar 16 is a square ferrule. In some areas of China, the style of the street lamp post is not a constant cylinder, and a prism-shaped lamp post also exists.
The horizontal distance between the rotating rod 151 and the display screen frame 11 is 20cm, and the distance between the rotating rod 151 and the display screen frame 11 ensures that the permanent magnet 153 cannot cause electromagnetic interference on the LED lamp screen 12.
Application example one
The first application example is explained based on the structure in the first embodiment, and specifically, the following is performed:
when the wind speed in the external environment increases but does not reach the typhoon level, as shown in fig. 9, the LED lamp 12 rotates by a certain angle under the action of the wind, then gradually returns due to the restoring force provided by the magnetic force of the permanent magnet 153, and finally, when the external wind speed is stabilized, the LED lamp 12 is still in the display frame 11.
Application example two
The second application example is explained based on the structure in the first embodiment, and specifically, the following is provided:
when the wind speed in the external environment reaches the typhoon degree, as shown in fig. 10, the strong wind force can make the LED lamp screen 12 continuously rotate for 360 degrees in the display frame 11, and the LED lamp screen 12 releases the pressure of the wind force on the windward side through rotation, so as to avoid the strong wind directly blowing the lamp post display screen 1. When the external wind is weakened, the LED screen 12 is finally stabilized in the display screen frame 11 by the restoring force provided by the permanent magnet 153.
Finally, it should be noted that: the above examples are only for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
