[0019] Preferably, a plurality of light strips are fixedly connected to the bottom side of the outer ring at equal intervals, and the light strips are located between two adjacent nozzles for illuminating the base column.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] By thickening the base pipe column and setting a water storage component inside the base pipe column, the anti-collision ability of the base pipe column itself is increased, while the occupation of the internal space of the base pipe column is reduced, ensuring the installation of street lamp components inside the base pipe column. At the same time, an anti-collision layer is set on the outside of multiple spiral water storage pipes. While ensuring the water storage capacity, the spiral water storage pipe adds a protective layer between the outer layer and the inner layer of the base pipe column to enhance the anti-collision ability. At the same time, even if it is hit, only the spiral water storage pipe at the hit position is broken, reducing the outflow of liquid when it is hit, and avoiding the damage to the internal components of the street lamp caused by a large amount of splashing liquid;

[0022] Rainwater is collected through the collection ring, and the rainwater is precipitated by the installation pipe. The rainwater is used for cooling and cleaning, which reduces the waste of water resources and the workload of manual water replenishment, ensuring the replenishment and use of the liquid inside the entire water storage component;

[0023] When the weight inside the water storage ring groove is greater than the supporting force of the support block, the sealing ring will be driven to move downward, thereby exposing the liquid inlet ring opening, and rainwater will be collected through the liquid inlet ring opening. The weight inside the sealing ring is reduced, and the sealing ring is reset and moved upward under the elastic support of the support block, and the liquid inlet ring opening is re-sealed, thereby avoiding evaporation of liquid inside the spiral water storage pipe, ensuring the collection of rainwater, and avoiding insufficient water when it is needed;

[0024] The sealing block can squeeze the liquid absorbed into the outlet pipe, so as to cool and clean the base pipe column under high temperature, and can cool and protect the internal components of the base pipe column. At the same time, there is no need to manually clean the base pipe column, so as to ensure the cleanliness of the street lamp;

[0025] After the collected rainwater is precipitated inside the spiral water storage pipe and the installation pipe, a large amount of precipitation will accumulate inside the installation pipe. When the evaporative liquid absorbs heat and evaporates, it drives the expansion bag to expand. The blocking ring will separate the precipitation and water inside the installation pipe to prevent the precipitation from moving up. When the expansion bag expands, it will drive the top rod to move down, contact and squeeze the sealing sheet to expose a certain space, so as to facilitate the sinking of the precipitation and avoid the accumulation of a large amount of precipitation inside the installation pipe, ensuring that the sprayed liquid has less impurities and avoiding a large amount of water marks after spraying;

[0026] Street lamps are used to illuminate the road, but some lamp holders cannot provide lighting below due to lack of light at night, rain or snow, which may cause pedestrians to collide with the lamps, posing a safety hazard. By setting light strips on the base column, light can be provided below the lamps, thereby improving the lighting effect at night and preventing collisions between pedestrians and lamps.

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] The terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not used to limit the scope of the present invention. Changes or adjustments to their relative relationships should be regarded as the scope of the present invention without substantially changing the technical content.

[0040] Reference Figure 1-Figure 10 , a street lamp holder protection device based on smart city, comprising: a mounting seat 1, a base column 2 fixedly connected above the mounting seat 1 and an opening and closing door 3 arranged on the bottom side of the base column 2, the opening and closing door 3 is used to open the inside of the base column 2 to repair the street lamp components inside, the base column 2 is provided with an installation cavity, the installation cavity is arranged on the upper side of the opening and closing door 3, a water storage component 4 is arranged inside the installation cavity, and a liquid inlet ring is opened on the upper side of the installation cavity;

[0041] The water storage assembly 4 includes a collecting ring 41, a plurality of spiral water storage pipes 42 and a plurality of mounting pipes 43. The collecting ring 41 is fixedly sleeved inside the mounting cavity and is located at the upper end of the mounting cavity. The plurality of spiral water storage pipes 42 are annularly fixedly connected to the bottom side of the collecting ring 41 and are in communication with the collecting ring 41. The plurality of spiral water storage pipes 42 form a protective pipe. The plurality of mounting pipes 43 are respectively fixedly connected to the bottom ends of the plurality of spiral water storage pipes 42.

[0042] A plurality of water spraying assemblies 5 are disposed between the installation tube 43 and the installation cavity. The plurality of water spraying assemblies 5 are respectively used to spray the liquid inside the plurality of installation tubes 43 onto the side wall of the base column 2 .

[0043] In the embodiment of applying the above technical solution,

[0044] The preferred technical solution in this embodiment is: by thickening the thickness of the base tube column 2 and setting a water storage component 4 inside the base tube column 2, the anti-collision ability of the base tube column 2 itself is increased, while the occupation of the internal space of the base tube column 2 is reduced, thereby ensuring the installation of street lamp components inside the base tube column 2.

[0045] At the same time, an anti-collision layer is set on the outside of the multiple spiral water storage pipes 42. While ensuring the water storage capacity, the spiral water storage pipes 42 add a protective layer between the outer layer and the inner layer of the base pipe column 2 to enhance the anti-collision ability. At the same time, even if it is hit, only the spiral water storage pipe 42 at the impacted position is broken, reducing the outflow of liquid when hit, and avoiding the damage to the internal components of the street lamp caused by a large amount of splashing liquid.

[0046] Rainwater is collected by the collecting ring 41 and precipitated by the installing pipe 43, and the rainwater is used for cooling and cleaning, thereby reducing the waste of water resources and the workload of manual water replenishment, and ensuring the replenishment and use of the liquid inside the entire water storage component 4.

[0047] The present invention can reduce the use space of the water storage component and increase the impact resistance of the lamp holder.

[0048] Reference Figure 2-4 A sealing assembly 6 is provided above the collecting ring 41, and the sealing assembly 6 is used to seal the liquid inlet ring; the sealing assembly 6 includes a plurality of supporting blocks 61 and a sealing ring 62, and the plurality of supporting blocks 61 are fixedly connected to the upper side of the collecting ring 41 in an equidistant ring shape, and the sealing ring 62 is fixedly connected to the upper side of the plurality of supporting blocks 61, and is clamped inside the liquid inlet ring.

[0049] The sealing ring 62 is provided with a water storage ring groove for collecting liquid. The support block 61 has a V-shaped cross section with the tip facing the outside of the base column 2. The support block 61 is made of elastic material.

[0050] When it rains, rainwater will slide down the street lamp and accumulate inside the water storage ring groove. When the weight inside the water storage ring groove is greater than the supporting force of the support block 61, the sealing ring 62 will be driven to move downward, thereby exposing the liquid inlet ring port, and rainwater will be collected through the liquid inlet ring port. After it rains, due to the contact between the water storage ring groove and the air, the evaporation rate of the water inside the water storage ring groove will be greater than the water inside the spiral water storage pipe 42, so that the weight inside the sealing ring 62 is reduced. The sealing ring 62 is reset and moved upward under the elastic support of the support block 61, and the liquid inlet ring port is re-seald, thereby avoiding the evaporation of the liquid inside the spiral water storage pipe 42, ensuring the collection of rainwater, and avoiding insufficient water for use when it is needed.

[0051] Especially in summer, there are often thunderstorms. After a short period of rainfall, it is necessary to avoid evaporation of the collected rainwater. The spiral water storage pipe 42 increases the water storage capacity while reducing the evaporation area at the upper end, thereby achieving the water storage effect to the greatest extent.

[0052] Reference Figure 3-5 The water spray assembly 5 includes an outer ring 51, a liquid guide tube 52, a liquid outlet pipe 53 and a nozzle 54. The outer ring 51 is fixedly sleeved on the upper end of the base pipe column 2. A bottom ring groove is provided at the bottom of the installation cavity close to the outer side of the base pipe column 2. The liquid outlet pipe 53 is provided on the upper side of the bottom ring groove. One end of the liquid outlet pipe 53 is provided on the lower side of the outer ring 51, and the other end is provided on the upper side of the bottom ring groove. One end of the liquid guide tube 52 is fixedly connected to the upper end of the installation tube 43, and the other end is fixedly connected to the side of the upper end of the liquid outlet pipe 53.

[0053] The nozzle 54 is installed through the outer ring 51. The spraying end of the nozzle 54 is set at an angle. A controllable one-way valve is set inside the nozzle 54 to control the opening and closing of the nozzle 54. When spraying, it will act on the base pipe column 2. The liquid is extracted from the inside of the installation pipe 43 through the liquid guide tube 52, and the liquid is filled into the liquid outlet pipe 53. Under high temperature conditions, the liquid in the liquid outlet pipe 53 is squeezed and sprayed out through the nozzle 54 to cool down and clean the base pipe column 2.

[0054] Reference Figure 6-7 An extrusion assembly 7 is provided inside the bottom ring groove, and the extrusion assembly 7 is used to squeeze and spray the liquid inside the liquid outlet pipe 53 through the nozzle 54.

[0055] The extrusion assembly 7 includes a liquid ring 71, an expansion tube 72 and a sealing block 73. The liquid ring 71 is arranged inside the bottom ring groove and contains evaporative liquid. The expansion tube 72 is arranged inside the liquid outlet pipe 53 and the bottom end is fixedly connected to the liquid ring 71. The sealing block 73 is fixedly connected to the upper end of the expansion tube 72 and is used to squeeze the liquid inside the liquid outlet pipe 53.

[0056] During the water spraying process, the liquid outlet pipe 53 is originally filled with liquid. After the liquid is sprayed, when the nozzle 54 is closed, the negative pressure inside the liquid outlet pipe 53 will extract the liquid from the connecting pipe 91. The liquid ring 71 is made of a heat-absorbing material, which can ensure that it absorbs heat under high temperature conditions, so that the evaporative liquid inside the liquid ring 71 evaporates. When the evaporative liquid inside the liquid ring 71 absorbs heat and evaporates, the evaporative liquid can be alcohol or mercury, etc., which will drive the expansion tube 72 to expand, causing the expansion tube 72 to extend. Through the deformation of the expansion tube 72, the sealing block 73 can squeeze the liquid absorbed into the liquid outlet pipe 53. Since the installation tube 43 and the liquid guide tube 52 are already filled with liquid, the squeezed liquid can only be sprayed out through the nozzle 54, so that the base column 2 is cooled and cleaned under high temperature conditions, and the internal components of the base column 2 can be cooled and protected. At the same time, there is no need to manually clean the base column 2 to ensure the cleanliness of the street lamp.

[0057] When the temperature drops and the evaporated liquid recovers, the closing of the nozzle 54 and the sliding down of the sealing block 73 will cause the inside of the liquid outlet pipe 53 to become negative pressure again, and the liquid is extracted from the inside of the mounting tube 43 through the liquid guide tube 52 again, thereby replenishing the liquid outlet pipe 53 with water to ensure subsequent water spraying.

[0058] Reference Figure 6-9 The bottom ends of the plurality of mounting tubes 43 are fixedly connected with a second collecting ring 8, the inside of the second collecting ring 8 is provided with a collecting cavity for collecting impurities, the bottom of the second collecting ring 8 is provided with a slag discharge pipe, the slag discharge pipe is used to discharge and clean the collected precipitates, the collecting cavity is connected with the mounting tube 43 through a chip guide port, the inside of the chip guide port is provided with an opening and closing ring 10, the inside of the opening and closing ring 10 is provided with a plurality of annular sealing sheets.

[0059] The installation tube 43 is provided with a guide assembly 9 inside, and the guide assembly 9 is used to guide the sediment inside the installation tube 43 into the second collecting ring 8 .

[0060] The outlet assembly 9 includes a connecting tube 91, an expansion bag 92, a blocking ring 93 and a push rod 94. The connecting tube 91 is an arc-shaped tube, and one end of the connecting tube 91 is connected to the liquid ring 71, and the other end is located inside the mounting tube 43. The expansion bag 92 is fixedly connected to the end of the connecting tube 91 located inside the mounting tube 43. The blocking ring 93 is fixedly sleeved on the expansion bag 92. The push rod 94 is fixedly connected to the bottom of the expansion bag 92 and is located directly above the center of the opening and closing ring 10.

[0061] In the process of collecting rainwater, since there is a lot of dust in the rainwater, if the base column 2 is cleaned and cooled directly by the collected rainwater, it is easy to cause a lot of water marks on the base, affecting the appearance and heat dissipation effect of the base.

[0062] After the collected rainwater is precipitated inside the spiral water storage pipe 42 and the mounting pipe 43, a large amount of precipitation will accumulate inside the mounting pipe 43. When the evaporative liquid absorbs heat and evaporates, it will be introduced into the expansion bag 92, thereby driving the expansion bag 92 to expand. When the expansion bag 92 drives the blocking ring 93 to expand and deform, the blocking ring 93 will separate the precipitation and water inside the mounting pipe 43 to prevent the precipitation from moving up. After the expansion bag 92 expands, it will drive the push rod 94 to move downward, so that the push rod 94 contacts the opening and closing ring 10, contacts and squeezes the sealing sheet, exposing a certain space, thereby facilitating the sinking of the precipitation. The settled precipitation will fall into the second collecting ring 8, and the precipitation will be collected by the second collecting ring 8 to avoid a large amount of precipitation from accumulating inside the mounting pipe 43, thereby ensuring that the sprayed liquid contains fewer impurities and avoiding a large amount of water marks after spraying.

[0063] The second collecting ring 8 is provided to collect the sediment, and the opening and closing ring 10 is used to block the sediment collected below, so as to prevent the sediment below from being impacted during the collection of rainwater and causing the transfer of the sediment.

[0064] Reference Figure 6 A placement space is provided at the bottom of the installation cavity, and a temperature regulating device 11 is provided inside the placement space. The regulating end of the temperature regulating device 11 is located inside the liquid ring 71 and is used to regulate the temperature inside the liquid ring.

[0065] The temperature regulating device 11 adjusts the temperature inside the liquid ring 71. The temperature regulating device 11 includes a condensation plate, a copper plate and a control module, which are used to absorb and release heat. The control module is digitally controlled to control the temperature inside the liquid ring. The temperature is effectively controlled. In summer, the outside temperature is high, resulting in continuous vaporization of the liquid inside the entire liquid ring 71, which makes it impossible to spray water intermittently and effectively cool the base pipe column. The condensation plate absorbs heat and intermittent water spraying can be performed for cooling. In winter, the copper plate can be used for heating to increase the temperature of the base pipe column 2 to prevent the base pipe column 2 from freezing and cracking.

[0066] Reference Fig.10 A plurality of light strips 12 are fixedly connected to the bottom side of the outer ring 51 at equal intervals. The light strips 12 are located between two adjacent nozzles 54 and are used to illuminate the base column 2 .

[0067] During the use of street lamps, they are used to illuminate the road. However, due to the lack of light at night, some street lamp holders cannot provide light below when it rains or snows, which can easily cause pedestrians to collide with the street lamps, posing a safety hazard. By arranging a light strip 12 on the base column 2, light can be provided below the street lamp, thereby improving the lighting effect at night and preventing pedestrians from colliding with the street lamp.

[0068] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
