Description

Technical Field

[0001] The invention relates to the technical field of LED lamps, and in particular to an outdoor dustproof LED lamp. Background Art

[0002] Outdoor LED lamps refer to lamps that can be used in outdoor environments such as courtyards, streets, parking lots, and construction sites. Outdoor mobile lighthouses are one type of them. Outdoor mobile lighthouses are mainly used in construction sites, emergency rescue sites, disaster sites, etc.; this type of lamp is mainly composed of a lamp head (LED lamp group), a lamp pole (retractable or foldable), a base (wheeled chassis), etc.

[0003] Existing lamp heads are usually provided with lampshades to protect the internal LED light groups. When an outdoor mobile lighthouse is located in a windy and sandy area for emergency rescue, the external wind and sand will constantly impact the lampshade, and the light-transmitting part of the lampshade will be worn and scratched, making the outer surface of the light-transmitting part blurred, thus reducing the light transmittance and shortening the service life of such lighthouses. If the wind and sand contain tiny stones, the tiny stones will directly impact the light-transmitting part of the lampshade, causing the light-transmitting part of the lampshade to shatter, allowing the wind and sand to directly enter the lamp head, causing damage to the internal LED light group, and then the lighting function cannot be realized, which will directly affect the rescue mission and cause greater losses.

DETAILED DESCRIPTION

[0020] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which the presently preferred embodiments of the present invention are shown. However, the present invention can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for the sake of thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person, and the positions and movement directions of the parts in all the following schemes are given in the following manner. Figure 2 direction as the reference.

[0021] Embodiment 1: When the existing mobile LED lighthouse is in use, if the wind and sand from the outside directly blow the front side of the lampshade, the sand will cause wear and tear on the windward side of the lampshade, and scratches will appear, which will reduce the light transmittance of the lampshade and further reduce the lighting effect of the lighthouse. In order to reduce the wear and tear of the lampshade and extend its service life, an outdoor dustproof LED lamp is proposed, which is as follows: Reference Figure 1-Figure 3 As shown, it includes: a mobile platform 1, on which a telescopic frame 2 is installed; a protective shell 3, fixedly connected to the telescopic part of the telescopic frame 2, and an LED light group 4 is installed in the protective shell 3; a winding shaft 5, rotatably connected to the protective shell 3, and a first elastic member is fixedly connected between the two, and a fixed rod 6 is arranged on the outer side of the protective shell 3; a protective cloth 7, one end of which is fixedly connected to the fixed rod 6, and the winding shaft 5 is fixedly connected to the other end of the protective cloth 7; a winding mechanism, which is arranged on the protective shell 3 and is used to wind up the protective cloth 7; a wind direction detection mechanism, which is arranged on the protective shell 3 and is used to detect the wind direction.

[0022] In the above scheme, a method of protecting the lampshade on the LED lamp group 4 is proposed, so as to extend its service life and reduce the wear of the lampshade; the mobile platform 1 can be a trailer platform, which is convenient for driving the lamp to move; the telescopic frame 2 is a self-locking telescopic rod, which can stop lifting and lowering at any position; the LED lamp group 4 is an existing structure, which includes a lampshade and an LED lamp; the first elastic member on the winding shaft 5 and the protective shell 3 is a torsion spring, which is used to drive the winding shaft 5 to rotate and reset; the protective cloth 7 is a wear-resistant, highly elastic and high-strength transparent film, so as to strengthen the protection of the lampshade and reduce the probability of damage to the lampshade while ensuring the transmittance; the winding shaft 5 is detachably installed. After the protective cloth 7 is damaged, the winding shaft 5 can be removed to replace the protective cloth 7. The winding shaft 5, the fixed rod 6 and the protective cloth 7 can be a whole for unified mass production; the figure shows the protective cloth 7 unfolded to cover the LED lamp group 4.

[0023] For further explanation, see Figure 3-Figure 5 As shown, the winding mechanism includes: a first conical wheel 21, which is rotatably connected to the protective shell 3; a plurality of rotating shafts 22, all of which are rotatably connected to the protective shell 3, and the first conical wheel 21 and the rotating shaft 22 are connected through a pulley belt transmission; the number of first pull ropes 23 is consistent with the number of rotating shafts 22, one end of which is fixedly connected to the fixed rod 6, and the rotating shaft 22 is fixedly connected to the other end of the adjacent first pull rope 23; a driving assembly, which is arranged on the protective shell 3, and is used to drive the first conical wheel 21 to rotate.

[0024] In the above scheme, a method of controlling the movement of the fixed rod 6 is mainly proposed, that is, to reel in the protective cloth 7; the outer side of the first conical wheel 21 is made of rubber; there are two rotating shafts 22 in this scheme, which are respectively located on the front and rear sides of the protective cloth 7, so that when the protective cloth 7 is pulled, the force on the protective cloth 7 is evenly distributed; the first pull rope 23 is made of a non-deformable material, such as a steel wire rope; the pulley belt between the first conical wheel 21 and the rotating shaft 22 can be replaced with a sprocket chain, and can also be replaced according to the actual use environment.

[0025] For further explanation, see Figure 2-Figure 5 As shown, the driving assembly includes: a first transmission member 31, which is rotatably connected to the protective shell 3, the first transmission member 31 is equipped with a magnetic coupler 32, and the magnetic coupler 32 is equipped with a second transmission member 33; a second conical wheel 34, which is splined to the first transmission member 31, and a second elastic member is arranged between the two, and the second conical wheel 34 is transmission-connected to the first conical wheel 21; a centrifugal detection assembly, which is arranged on the second transmission member 33, and is used to detect wind force and control the rotation of the second transmission member 33.

[0026] In the above scheme, a method of driving the first conical wheel 21 to rotate is proposed to realize the winding and releasing of the protective cloth 7; the magnetic coupler 32 is an existing device, which is located between the first transmission member 31 and the second transmission member 33 to ensure the power transmission between the two; the outer side of the second conical wheel 34 is also set to rubber material to ensure the stable transmission of power between the second conical wheel 34 and the first conical wheel 21, and the second elastic member between the second conical wheel 34 and the first transmission member 31 is a spring, which is used to drive the second conical wheel 34 to move upward, and the second elastic member between the second conical wheel 34 and the first transmission member 31 is initially in a compressed and stored state.

[0027] For further explanation, see Figure 4 As shown, the centrifugal detection assembly includes: a fixed shaft 41, which is rotatably connected to the second transmission member 33; a wind cup 42, which is installed on the fixed shaft 41; a limit block 43, which is slidably connected to the fixed shaft 41, and a third elastic member is arranged between the two, and the limit block 43 limits the second transmission member 33.

[0028] In the above scheme, the wind cup 42 is an existing structure, and there are four of them; the number of the limit blocks 43 in this scheme is ten, and they are distributed circumferentially, the limit blocks 43 are wedge-shaped blocks, and the direction of the inclined surface on the limit blocks 43 is opposite to its rotation direction; the third elastic member between the limit block 43 and the fixed shaft 41 is a tension spring, which is used to drive the limit block 43 to reset, and when the limit block 43 moves under the centrifugal force, the third elastic member between the limit block 43 and the fixed shaft 41 is stretched.

[0029] For further explanation, see Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, the wind direction detection mechanism includes: a wind vane 51, which is rotatably connected to the first transmission member 31; a support rod 52, which is fixed to the wind vane 51; a blocking block 53, which is splined to the protective shell 3, the support rod 52 is in contact with the blocking block 53, and the blocking block 53 is in contact with the second conical wheel 34; the blocking block 53 has a protrusion 531, a recessed portion 532 and a transition portion 533, and the sum of the central angles of the protrusion 531 and the transition portion 533 projected on the horizontal plane is 120°.

[0030] In the above scheme, the weather vane 51 is an existing structure, which is used to indicate the wind direction, so that when the wind blows towards the LED light group 4, the protective cloth 7 can block the LED light group 4; the blocking block 53 is used to determine when to use the protective cloth 7 to block the LED light group 4; the projection 531, the recessed portion 532 and the transition portion 533 in the horizontal direction are a complete circle, wherein the central angle corresponding to the projection 531 and the transition portion 533 is 120°, that is, when the wind vane 51 points to the left within a range of 120°, the support rod 52 contacts with the projection 531 or the transition portion 533, and if the wind vane 51 points to the right within a range of 240°, the support rod 52 contacts with the recessed portion 532.

[0031] Working principle: The state shown in the figure of this application is that the protective cloth 7 has blocked the LED light group 4, that is, the left side of the lamp is the wind-exposed side, and the following description is explained in the order from the protective cloth 7 in the rolled-up state to the unfolded state (that is, from not exposed to wind to exposed to wind), and the initial state takes the wind vane 51 facing the right side as an example.

[0032] When using the lamp for lighting, the user moves the lamp to the target position and then turns on the LED light group 4. When wind blows, the wind blows toward the wind cup 42 and causes it to rotate. The wind cup 42 drives the limit block 43 to rotate through the fixed shaft 41. At this time, the fixed shaft 41 and the second transmission member 33 rotate relative to each other.

[0033] When the wind force gradually increases, the rotation speed of the wind cup 42 gradually increases, and the rotation speed of the fixed shaft 41 also gradually increases. The limit block 43 begins to move under the action of centrifugal force and stretches the third elastic member thereon. As the limit block 43 moves, until the limit block 43 moves to contact and enter the second transmission member 33, the limit block 43 drives the second transmission member 33 to start rotating. The second transmission member 33 drives the first transmission member 31 to rotate through the magnetic coupling 32, and the first transmission member 31 drives the second conical wheel 34 to rotate.

[0034] During the rotation of the wind cup 42, the wind vane 51 rotates due to the wind. Taking the front side of the lamp as an example, the wind blows the wind vane 51, and the arrow of the wind vane 51 points to the front side. The wind vane 51 drives the support rod 52 to rotate to the front side, and the support rod 52 slides along the recessed portion 532. Under the elastic action of the second elastic member between the second conical wheel 34 and the first transmission member 31, the second conical wheel 34 is located on the upper side. At this time, the second conical wheel 34 is not in contact with the first conical wheel 21, and the blocking block 53 is located on the upper side and fits with the support rod 52.

[0035] Taking the left side of the lamp as an example, the wind blows the wind vane 51, and the arrow of the wind vane 51 points to the left. The wind vane 51 drives the support rod 52 to rotate to the left. During the rotation of the support rod 52, the support rod 52 squeezes the transition portion 533, and the blocking block 53 gradually moves downward. The blocking block 53 drives the second conical wheel 34 to move downward, and the second elastic member between the second conical wheel 34 and the first transmission member 31 is compressed until the support rod 52 contacts the protruding portion 531, and the second conical wheel 34 contacts the first conical wheel 21. At this time, the second conical wheel 34 drives the first conical wheel 21 to rotate, and the first conical wheel 21 drives the rotating shaft 22 to rotate through the pulley belt, and the rotating shaft 22 reels the first pull rope 23. The first pull rope 23 drives the fixed rod 6 to move upward, and the fixed rod 6 stretches the protective cloth 7 upward. The protective cloth 7 gradually blocks the LED lamp group 4, and the protective cloth 7 drives the winding shaft 5 to rotate, and the winding shaft 5 and the first elastic member on the protective shell 3 accumulate force.

[0036] During the process of the fixing rod 6 moving upward, until the fixing rod 6 moves to the extreme position, the fixing rod 6 fully unfolds the protective cloth 7, and the protective cloth 7 completely blocks the left side of the LED lamp group 4. In this way, the protective cloth 7 blocks the LED lamp group 4, so that the external wind and sand will not directly contact the lampshade of the LED lamp group 4, thereby reducing the probability of damage to the LED lamp group 4 by the wind and sand. At the same time, the protective cloth 7 buffers the impact of the wind and sand, reduces the impact force on the LED lamp group 4, and thereby reduces the probability of the lampshade of the LED lamp group 4 being broken by the wind and sand.

[0037] When the fixing rod 6 moves to the extreme position, the first pull rope 23 and the rotating shaft 22 cannot rotate, that is, the first cone wheel 21 stops rotating and the second cone wheel 34 cannot rotate. At this time, the magnetic coupler 32 works to make the first transmission member 31 rotate normally.

[0038] When the wind stops, the reel 5 rotates in the opposite direction under the action of the first elastic member on the reel 5 and the protective shell 3 and reels the protective cloth 7, i.e., stops shielding the LED light group 4, reducing the probability of damage to the protective cloth 7 by external objects, thereby extending its service life.

[0039] Embodiment 2: Based on Embodiment 1, in order to improve the stability of the protective cloth 7 and prevent the protective cloth 7 from shaking or even being damaged by the side wind when shielding the LED light group 4, the following solution is proposed, specifically: Reference Figure 2 and Figure 10-12 As shown, it also includes: a tightening mechanism, which has two, both are arranged in the protective shell 3, and is used to tighten the protective cloth 7. The tightening mechanism includes: a first hydraulic rod 61, which has a row, and the number of the first hydraulic rods 61 in each row is two, and each row of the first hydraulic rods 61 is fixed in the protective shell 3; a first plate 62, which is fixed to the telescopic parts of all the first hydraulic rods 61; a second plate 63, which is slidably connected to the telescopic parts of all the first hydraulic rods 61, and the protective cloth 7 is located between the first plate 62 and the second plate 63, and a fourth elastic member is arranged between the second plate 63 and the protective shell 3; a trigger component, which is arranged on the protective shell 3, and is used to detect the position of the fixing rod 6.

[0040] In the above scheme, a method of pulling the unfolded protective cloth 7 is proposed to make it in a taut state, so as to improve the stability of the protective cloth 7 and enhance the protection effect of the LED light group 4; the two tightening mechanisms are respectively located on the front and rear sides of the LED light group 4; the first hydraulic rod 61 is filled with hydraulic oil, and there are two of them, which are respectively distributed on the upper and lower sides of the protective cloth 7; the positions of the two second plates 63 correspond to the two first plates 62, and the fourth elastic member between the second plate 63 and the protective shell 3 is a spring, which is used to drive the first plate 62 to reset.

[0041] For further explanation, see Figure 2 , Figure 6 , Fig.10 , Fig.13 and Fig.14 As shown, the trigger assembly includes: a trigger telescopic rod 71, which is fixed to the side of the protective shell 3 close to the fixed rod 6; a ring plate 72, which is rotatably connected to the second transmission member 33, and the ring plate 72 is fixed with a pushing telescopic rod 73, and the fixed part of the pushing telescopic rod 73 is connected to the fixed part of the trigger telescopic rod 71 through a connecting pipe; a fixed plate 74, which is fixed to the telescopic part of the pushing telescopic rod 73 and is slidably connected to the protective shell 3, and the fixed plate 74 is rotatably connected to the limiting frame 75, and a fifth elastic member is arranged between the limiting frame 75 and the second transmission member 33, and the limiting frame 75 is slidably connected to the second transmission member 33; a transmission assembly, which is arranged on the second transmission member 33, and is used to drive the telescopic part of the first hydraulic rod 61 to move.

[0042] In the above scheme, when the fixed rod 6 moves to the limit position, the telescopic part of the trigger telescopic rod 71 is compressed to the limit; the fixed part of the trigger telescopic rod 71 and the fixed part of the push telescopic rod 73 are filled with hydraulic oil; when the telescopic part of the trigger telescopic rod 71 contracts, the hydraulic oil therein is pumped to the fixed part of the push telescopic rod 73, pushing the telescopic part of the telescopic rod 73 to extend; the limit frame 75 is composed of a circular plate and a plurality of circular rods; the fifth elastic member between the limit frame 75 and the second transmission member 33 is a tension spring, which is used to drive the limit frame 75 to move and reset; the fixed plate 74 is slidably connected to the protective shell 3 through the bracket (such as Fig.13 as shown).

[0043] For further explanation, see Figure 4 As shown, the transmission assembly includes: a centrifugal block 81, which has a plurality of them, all of which are slidably connected to the second transmission member 33, and a sixth elastic member is fixedly connected between the centrifugal block 81 and the second transmission member 33, and a limit frame 75 limits the centrifugal block 81; a rotating ring 82, which is slidably connected to the second transmission member 33, and a second pull rope 83 is fixedly connected between the centrifugal block 81 and the rotating ring 82; a transmission frame 84, which is slidably connected to the second transmission member 33 and is rotatably connected to the rotating ring 82; a second hydraulic rod 85, which is fixedly connected to the protective shell 3 and is connected to all the first hydraulic rods 61, and the telescopic part of the second hydraulic rod 85 is fixedly connected to the transmission frame 84.

[0044] In the above scheme, the number of centrifugal blocks 81 is four, the number of round rods on the limiting frame 75 is also four, an inclined surface is arranged on the lower side of the round rods on the limiting frame 75, a groove is arranged on the upper side of the centrifugal block 81, and the round rods of the limiting frame 75 are used to limit the grooves of the centrifugal block 81; the sixth elastic member between the centrifugal block 81 and the second transmission member 33 is a tension spring, which is used to drive all the centrifugal blocks 81 to move in opposite directions; the second pull rope 83 is made of a non-deformable material, such as a steel wire rope; the second hydraulic rod 85 is filled with hydraulic oil, and when the telescopic part of the second hydraulic rod 85 moves upward, all the hydraulic oil in the first hydraulic rod 61 enters the second hydraulic rod 85, and the telescopic part of the first hydraulic rod 61 retracts.

[0045] Working principle: During the movement of the fixed rod 6, when the fixed rod 6 contacts the telescopic part of the trigger telescopic rod 71, the fixed rod 6 begins to squeeze the telescopic part of the trigger telescopic rod 71, and the hydraulic oil in the trigger telescopic rod 71 gradually flows into the telescopic rod 73, pushing the telescopic part of the telescopic rod 73 to extend and drive the fixed plate 74 to move upward, and the fixed plate 74 drives the limit frame 75 to move and stretch the fifth elastic member, and the round rod of the limit frame 75 moves upward and disengages from the groove of the centrifugal block 81.

[0046] During the rotation of the above-mentioned second transmission member 33, the second transmission member 33 drives the centrifugal block 81 and the rotating ring 82 to rotate synchronously, and the rotating ring 82 and the transmission frame 84 rotate relative to each other. When the limit frame 75 releases the limit on the centrifugal block 81, the centrifugal block 81 begins to move due to the centrifugal force and stretches the sixth elastic member between the centrifugal block 81 and the second transmission member 33. All the centrifugal blocks 81 move in reverse and pull the adjacent second pull rope 83 to move. The second pull rope 83 drives the rotating ring 82 to move upward, and the rotating ring 82 drives the transmission frame 84 to move. The transmission frame 84 drives the telescopic part of the second hydraulic rod 85 to move upward. The second hydraulic rod 85 extracts the hydraulic oil in all the first hydraulic rods 61, and the telescopic part of the first hydraulic rod 61 begins to retract.

[0047] During the retraction of the telescopic portion of the first hydraulic rod 61, the telescopic portion of the first hydraulic rod 61 drives the first plate 62 to move backward, and the second plate 63 cannot move due to the action of the fourth elastic member thereon. The telescopic portion of the first hydraulic rod 61 moves relative to the second plate 63, and the distance between the first plate 62 and the second plate 63 gradually decreases.

[0048] After the first plate 62 and the second plate 63 are tightly fitted with the protective cloth 7, the first plate 62 and the second plate 63 clamp the protective cloth 7, and as the telescopic part of the first hydraulic rod 61 retracts, the first plate 62 and the second plate 63 jointly drive the front and rear sides of the protective cloth 7 to move to the right (the fourth elastic member between the second plate 63 and the protective shell 3 is compressed), and at the same time the protective cloth 7 begins to stretch slowly, and the front and rear sides of the protective cloth 7 gradually move to the front and rear sides of the protective shell 3 respectively, and at the same time the protective cloth 7 is fitted with the left side of the protective shell 3, and the front and rear sides of the protective cloth 7 block the gap between the protective cloth 7 and the protective shell 3, thereby reducing the side wind entering between the protective cloth 7 and the protective shell 3 and causing the protective cloth 7 to shake, thereby improving the stability of the protective cloth 7, and further improving the protection effect on the LED lamp group 4.

[0049] After the wind stops, the telescopic portion of the first hydraulic rod 61 is reset, and the first plate 62 and the second plate 63 release the clamping of the protective cloth 7 .

[0050] Embodiment 3: Based on Embodiment 2, in order to ensure the buffering effect of the protective cloth 7 on the impact of wind and sand, the following scheme is proposed, specifically: Reference Figure 10-12As shown, it also includes: two support columns 91, both of which are fixed to one side of the protective shell 3 close to the winding shaft 5, and the support columns 91 are located between the protective cloth 7 and the LED lamp group 4, the support columns 91 are used to support the protective cloth 7, the two support columns 91 are located between the two first plates 62, and the outer side of the support columns 91 is a smooth surface, so as to reduce the wear of the protective cloth 7, and in the process of the first plate 62 and the second plate 63 driving the side of the protective cloth 7 to move backward, when the protective cloth 7 contacts the support columns 91, the support columns 91 block the protective cloth 7, so that the unbent part of the protective cloth 7 stops moving, and then the front and rear sides of the protective cloth 7 continue to move to the right, so that the protective cloth 7 is deformed into a U shape, and under the blocking action of the two support columns 91, a distance is left between the left side of the protective cloth 7 and the protective shell 3, and this gap is used to buffer the impact of wind and sand, thereby reducing the impact of wind and sand on the lampshade on the LED lamp group 4.

[0051] While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
