Technical Field

[0001] The invention relates to the technical field of public facilities, and in particular to a public art lighting device capable of spraying and reducing dust. Background Art

[0002] Public art lighting, as an important part of urban landscape design, not only enhances the visual enjoyment of the city at night, but also injects vitality into the city.

[0003] Although public art lighting adds a different charm to the city night with its unique design concept and innovative means, it is only used for lighting and has no other additional functions. At night, except as an element of the city, it has no effect on improving the air environment. Summary of the invention

[0004] In order to solve the problems existing in the background technology, the present invention provides a public art lighting device capable of spraying and dust reduction, comprising a pole assembly, a lamp fixing assembly, a spray assembly, an upper rotating lamp assembly and a water-dynamic component, wherein the pole assembly comprises a pole and a bent rod, the spray assembly comprises a connecting outer seat and a spray main shell, the upper rotating lamp assembly comprises a rotating lamp body and a rotating central gear, and the water-dynamic component comprises a water-dynamic chamber and an inner water pipe;

[0005] The bent rod is fixedly connected to the upper end of the vertical pole to form a whole. The lamp fixing assembly is installed on the inner arc side of the bent rod. The connecting outer seat is fixedly connected to the top of the vertical pole. The spray main shell is fixedly arranged on the upper end of the connecting outer seat, and spray micro holes are opened on both sides of the outer lower side. The inner middle part of the rotating lamp body is screwed to the lower middle part of the spray main shell. The rotating center gear is fixedly connected to the outer middle part of the rotating lamp body. A rotating connecting gear is screwed to one side of the upper end of the connecting outer seat, and the rotating connecting gear is meshed with the rotating center gear.

[0006] The hydraulic chamber is fixedly connected to the inner cavity connected to the outer seat, the inner water pipe is buried in the inner hole formed by the vertical rod and the bent rod, and is connected to the inner cavity of the hydraulic chamber. The inner cavity of the hydraulic chamber is also horizontally connected to a hydraulic impeller, and a hydraulic bevel gear is inserted into the outer shaft end of the hydraulic impeller. The hydraulic bevel gear is transmission-connected to the rotating connecting gear, and the top end of the hydraulic chamber is connected to the inner cavity of the spray main shell.

[0007] The use process of the technical solution of the present invention is as follows:

[0008] The solid lamp body is a spherical structure, connected to the external power supply, and plays the role of daily lighting;

[0009] The rotating lamp body has the same outline shape as the spray main shell, and the rotating lamp body is rotated on the lower side of the spray main shell, and the rotating lamp body can be charged by solar energy;

[0010] Spray micro-holes are provided on both sides of the outer bottom surface of the spray main shell. The inner water pipe is connected with the inner cavity of the spray main shell through the water dynamic cavity, and can provide water supply with a certain pressure to the inner cavity of the spray main shell, so as to form spray downward from the spray micro-holes.

[0011] After the water supply enters the inner cavity of the hydraulic chamber, it will drive the rotation of the hydraulic impeller, and the hydraulic impeller can drive the rotation of the hydraulic bevel gear, so that the hydraulic bevel gear and the rotating connecting gear form a matching transmission, so that the rotating connecting gear and the rotating central gear can form a matching transmission, driving the rotating lamp body to rotate with the spray main shell as the reference;

[0012] When the rotating lamp body rotates, a dynamic lighting effect can be formed. When the rotating lamp body rotates relative to the spray main shell, the water mist sprayed from the spray micropores can be continuously cut off, so that the water mist sprayed from the spray micropores can also form a dynamic spraying effect.

[0013] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0014] (1) The present invention first uses the fixed integral structure formed by connecting the bent rod and the vertical rod as the basis to form a more beautiful structure, and installs the fixed lamp body on the bent rod, which can first play the role of daily lighting;

[0015] (2) The present invention not only has a spray main shell fixedly connected to the top of the vertical pole, but also has a rotating lamp body screwed to the lower side of the spray main shell. The rotating lamp body itself is powered by solar energy, which can save energy. When the external water supply provides water to the spray main shell through the inner water pipe, the water impeller will be driven to rotate in the process of passing through the inner cavity of the hydraulic chamber, so that the hydraulic bevel gear drives the rotation of the rotating center gear through the transmission mechanism, thereby driving the rotating lamp body to rotate around the spray main shell. The rotating action of the rotating lamp body can not only form its own dynamic lighting effect and improve the appreciation, but also can cut off the water mist sprayed from the spray micropores through continuous rotation, so that the water mist sprayed from the spray micropores can also be sprayed into the external environment in a dynamic form, further improving the artistic appreciation effect.

[0037] The bent rod 104 in the vertical rod assembly 1 is fixedly connected to the upper end of the vertical rod 103 to form an integral structure. The fixed lamp assembly 2 is installed on the inner arc side of the bent rod 104 to play the main lighting role. The connecting outer seat 301 is fixedly connected to the top of the vertical rod 103. The spray main shell 303 is fixedly arranged at the upper end of the connecting outer seat 301, and spray microholes 305 are opened on both sides of the outer lower side. The inner middle part of the rotating lamp body 401 is screwed with the lower middle part of the spray main shell 303, and the spray main shell 303 and the rotating lamp body 401 are both C-shaped three-dimensional structures. The inner surface of the rotating lamp body 401 fits with the outer surface of the spray main shell 303. The rotating center gear 402 is fixedly connected to the middle part of the outer end of the rotating lamp body 401, and a rotating connecting gear 405 is screwed on one side of the upper end of the connecting outer seat 301, and the rotating connecting gear 405 is meshed with the rotating center gear 402, so that the rotating lamp body 401 can rotate relative to the spray main shell 303.

[0038] The hydraulic chamber 501 is fixedly connected to the inner cavity connected to the outer seat 301, and the inner water pipe 502 is buried in the inner hole formed by the vertical rod 103 and the curved rod 104, and is connected to the inner cavity of the hydraulic chamber 501. The inner cavity of the hydraulic chamber 501 is also horizontally connected to a hydraulic impeller 504, and the outer shaft end of the hydraulic impeller 504 is inserted with a hydraulic bevel gear 505. The hydraulic bevel gear 505 is transmission-connected to the rotating connecting gear 405, and the top of the hydraulic chamber 501 is connected to the inner cavity of the spray main shell 303.

[0039] Here’s how it works:

[0040] The device is installed outdoors and requires the support of electricity and water. It can be used for lighting and also forms a spray dust removal effect for the outdoor environment.

[0041] The lamp body 201 is a spherical structure, connected to an external power supply, and serves as daily lighting;

[0042] The rotating lamp body 401 has the same outline shape as the spray main shell 303, and the rotating lamp body 401 is rotatably arranged on the lower side of the spray main shell 303, and the rotating lamp body 401 can be charged by solar energy;

[0043] Spray micro holes 305 are provided on both sides of the outer bottom surface of the spray main shell 303. The inner water pipe 502 is connected with the inner cavity of the spray main shell 303 through the water dynamic cavity 501, and can provide water supply with a certain pressure to the inner cavity of the spray main shell 303, so as to form spray downward from the spray micro holes 305.

[0044] After the water supply enters the inner cavity of the water dynamic chamber 501, it will drive the rotation of the water dynamic impeller 504, and the water dynamic impeller 504 can drive the rotation of the water dynamic bevel gear 505, so that the water dynamic bevel gear 505 and the rotating connecting gear 405 form a matching transmission, so that the rotating connecting gear 405 and the rotating central gear 402 form a matching transmission, driving the rotating lamp body 401 to rotate with the spray main shell 303 as the reference;

[0045] When the rotating lamp body 401 rotates, a dynamic lighting effect can be formed. When the rotating lamp body 401 rotates relative to the spray main shell 303, the water mist sprayed from the spray microholes 305 can be continuously cut off, so that the water mist sprayed from the spray microholes 305 can also form a dynamic spraying effect.

[0047] The inner hole of the vertical rod 103 is connected to the inner cavity of the base 101;

[0048] A main controller 105 is also mounted and fixed on the bottom surface of the inner cavity of the base 101 to control the automatic operation of the device;

[0049] The lamp fixing base 106 is fixedly connected to the lower end of the inner arc side of the curved rod 104 , and the lamp fixing top base 107 is fixedly connected to the upper end of the inner arc side of the curved rod 104 .

[0054] An inner center seat 407 is fixed to the inner center of the rotating lamp body 401, and the rotating center gear 402 is installed and fixed to the outer side of the lower end of the inner center seat 407;

[0055] The rotating lamp body 401 is rotatably connected to the outside of the bottom connecting column 304 through the inner middle seat 407;

[0056] A transmission rotary seat 403 is fixedly mounted on the bottom of the main body of the cover plate 306, a transmission shaft 404 is rotatably connected in the transmission rotary seat 403, and a rotationally connected gear 405 is plugged and fixed on the top of the transmission shaft 404;

[0057] A sensing switch 406 is installed on one side of the inner surface of the rotating lamp body 401 and the outer side of the spray main shell 303, which can sense the position where the rotating lamp body 401 rotates to overlap with the spray main shell 303.

[0058] Solar panels 408 are fixedly mounted on the upper parts of both sides of the outer side of the rotating lamp body 401 . The solar panels 408 can not only provide power to the rotating lamp body 401 , but also provide power to the induction switch 406 .

[0059] The specific structure of the water dynamic component 5 is as follows: Figure 8 , Fig. 9 and Fig.10 As shown, the water inlet end of the inner water pipe 502 passes through the side wall of the base 101 and is connected to the external water channel. The water inlet valve 503 is fixedly installed at the water inlet end of the inner water pipe 502 and is electrically connected to the main controller 105. The main controller 105 can automatically control the opening of the water inlet valve 503 and the opening time of the water inlet valve 503, so that the inner water pipe 502 supplies water to the spray main shell 303 within a set time period.

[0060] The connecting bevel gear 506 is plugged and fixed at the bottom end of the transmission shaft 404, and meshes with the water-dynamic bevel gear 505, so that after the water-dynamic impeller 504 drives the water-dynamic bevel gear 505 to rotate, the water-dynamic bevel gear 505 and the connecting bevel gear 506 form a matching transmission, and the connecting bevel gear 506 can coaxially drive the rotation of the rotating connecting gear 405 through the transmission shaft 404, so that the rotating connecting gear 405 can form a matching transmission with the rotating central gear 402;

[0061] An outer rotating seat 507 and an inner rotating seat 508 are fixedly installed on both sides of the cavity wall of the hydraulic cavity 501. The inner shaft end of the hydraulic impeller 504 is rotatably connected to the inner rotating seat 508. The outer shaft end of the hydraulic impeller 504 is sealed and rotated out of the outer rotating seat 507 and fixedly connected to the hydraulic bevel gear 505.

[0062] The top outlet of the hydraulic chamber 501 is connected to a diffusion bucket 509, and a dispersion tube 510 is installed and fixed in the inner hole of the bottom connecting column 304 and connected to the upper end of the diffusion bucket 509. A dispersion hole 511 is arranged in a circular array in the main body of the dispersion tube 510, so that the pressurized water source flowing from the hydraulic chamber 501 into the diffusion bucket 509 will be evenly distributed from each group of dispersion holes 511 to the inner cavity of the spray main shell 303, so that the pressure of the water body at various locations in the inner cavity of the spray main shell 303 is relatively uniform, so that the water mist of each group of spray micropores 305 can be sprayed out evenly.

[0063] The electric drive component 6 connected to the outer seat 301 on the bottom surface of the inner cavity is as follows Fig.11 As shown, the telescopic electric cylinder 602 is installed and fixed on the bottom surface of the inner cavity connected to the outer seat 301, the outer shaft end of the water-dynamic impeller 504 is also plugged and fixed with a water-dynamic gear 601, the top of the telescopic rod of the telescopic electric cylinder 602 is fixedly installed with a driving motor 603, and the driving gear 604 is plugged and fixed in the rotating shaft of the driving motor 603, and under the operating condition that the telescopic electric cylinder 602 drives the driving motor 603 and the driving gear 604 to switch the operation, the driving gear 604 can be meshed and switched with the water-dynamic gear 601;

[0064] The driving motor 603 and the telescopic cylinder 602 are both electrically connected to the main controller 105 through the electric drive connection line 605. The electric drive connection line 605 passes through the main body connected to the outer seat 301 and enters the inner holes of the vertical rod 103 and the curved rod 104. The electric drive connection line 605 is also waterproof to prevent the water seeping from the inner water pipe 502 from causing a short circuit between the electric drive connection line 605 and the lamp fixing line 202.

[0065] The purpose of installing the electric drive component 6 in the device is not only to ensure that after the telescopic electric cylinder 602 drives the driving gear 604 to disengage from the water-dynamic gear 601, the electric drive component 6 will not interfere with the rotation of the water-dynamic bevel gear 505 driven by the water in the water-dynamic chamber 501 through the water-dynamic impeller 504, but also to ensure that in the absence of hydraulic drive, after the telescopic electric cylinder 602 drives the driving gear 604 to engage with the water-dynamic gear 601, the rotating lamp body 401 can still be driven to rotate relative to the spray main housing 303 through the transmission mechanism;

[0066] The purpose of setting up the electric drive component 6 is that when the device is not in use, the automatic rotation action formed by the driving motor 603 to drive the driving gear 604 and the hydraulic gear 601 can make the rotating lamp body 401 automatically rotate and stop relative to the spray main shell 303. In conjunction with the induction formed by the induction switch 406, the induction switch 406 can send a signal to the main controller 105 to stop the driving motor 603 after the rotating lamp body 401 rotates to a position that is opposite and overlaps with the spray main shell 303, so that when the device is not in use, the rotating lamp body 401 can be aligned and overlapped with the spray main shell 303.
