Description

Technical Field

[0001] The present invention relates to the technical field of lighting equipment, and more particularly to an energy-saving lighting device for building construction. Background Art

[0002] Lighting is a measure that uses various light sources to illuminate work and living places or individual objects. The use of sunlight and sky light is called "natural lighting"; the use of artificial light sources is called "artificial lighting". The primary purpose of lighting is to create good visibility and a comfortable and pleasant environment.

[0003] For construction sites that have not yet completed construction, since the power supply facilities are not yet complete, in the absence of sufficient natural light, they must rely on lighting equipment equipped with batteries to provide the necessary lighting to ensure that operations on the site can proceed smoothly.

[0004] In construction sites, due to the particularity of environmental conditions, the dust content is often high. Various heavy machinery and equipment used in the construction process, such as cranes, excavators, etc., will disturb the air and generate airflow. In addition, the handling and stacking of construction materials may also change the local airflow pattern and increase the wind speed. Therefore, this high-concentration dust environment can easily cause dust particles to adhere to the surface of the lighting lamp, forming a layer of dust cover, which will significantly reduce the lighting effect of the lighting lamp, making the light dim and unable to meet the construction site's demand for lighting brightness; therefore, in order to effectively improve the lighting effect and ensure the safety and work efficiency of the construction area, higher-power lighting lamps are usually used to compensate for the impact of dust on the lighting lamp. This is because more powerful lighting lamps can provide stronger light output and maintain sufficient light intensity even when covered in dust, thereby ensuring that the lighting needs of the construction site are met; however, for portable lighting devices powered by batteries, as the power of the lighting lamp increases, its power consumption will also increase significantly accordingly, which causes the battery to consume power faster and thus requires a higher charging frequency; this frequent charging demand not only increases the complexity of the operation, but the charging process takes time and requires special charging equipment and personnel to manage the process, which is especially inconvenient for the daily operation of the construction site in remote construction locations.

[0005] Therefore, an energy-saving lighting device for building construction is proposed. Summary of the invention

[0006] In view of the problems existing in the prior art, an object of the present invention is to provide an energy-saving lighting device for building construction, which can improve the convenience of using the lighting device.

[0007] To solve the above problems, the present invention adopts the following technical solutions.

[0008] An energy-saving lighting device for building construction comprises a frame, the frame is provided with wheels, so as to facilitate pushing the frame, a telescopic rod is rotatably mounted on the frame, a plurality of lamp heads are provided on the output end of the telescopic rod, and the lamp heads can be driven to rotate by rotating the telescopic rod, thereby changing the irradiation direction of the lamp heads; a storage battery for powering the lamp heads is provided in the frame, and the lamp heads are connected in series with the storage battery;

[0009] A mounting rod is fixedly mounted on the output end of the telescopic rod, a lampshade is detachably mounted on the mounting rod, and the lamp head is evenly mounted on the inner wall of the lampshade in a circular manner;

[0010] A lens is fixedly mounted on the surface of the lampshade, and the lens is used to protect the lamp holder and prevent dust from directly adhering to the surface of the lamp holder;

[0011] A sleeve is inserted and rotatably mounted on the side wall of the lens, a scraper for scraping the lens is fixedly mounted on the side wall of the sleeve, and a driving mechanism for driving the sleeve to rotate is arranged on the lampshade;

[0012] There are solar panels on the mounting poles, which are used to charge the batteries. Therefore, when there is sufficient light, the staff can push the frame into the sun to charge the batteries through the solar panels.

[0013] Among them, solar panels charging batteries is an existing technology and will not be described in detail;

[0014] A cavity is provided on the scraper, an air hole is provided on the side wall of the cavity close to the lens, an air supply mechanism for supplying air to the cavity is provided on the mounting rod, and a prompt mechanism matched with the lamp holder is provided on the vehicle frame.

[0015] Furthermore, the driving mechanism includes a flow guide tube evenly inserted on the inner side wall of the sleeve, the flow guide tube is located at a position where the sleeve extends outside the lampshade, the plurality of flow guide tubes are evenly distributed around the circumference, the number of the flow guide tubes is at least 6, and the flow guide tubes are inclined; the angle between the line between one end of the flow guide tube close to the center of the longitudinal section of the sleeve and the center of the longitudinal section of the sleeve and the flow guide tube is 60 degrees to 90 degrees;

[0016] The sleeve is a heat-insulating sleeve, and an inner heat-conducting rod extending into the lampshade is embedded on the inner wall of the sleeve near one end of the lampshade, so that the heat generated by the lamp head in the lampshade during operation will be transferred to the inside of the sleeve through the heat-conducting rod;

[0017] The flow guide pipe is a heat-insulating pipe, and a heat-conducting sheet extending to the outside of the sleeve is embedded on the inner end wall of the flow guide pipe;

[0018] The sleeve is filled with liquid, and the heat conducting sheet is fixedly embedded in the sleeve. The liquid in the sleeve is ether, and the liquid level in the sleeve is located below the horizontal plane where the center of the longitudinal section of the sleeve is located. The sleeve is in a sealed state, so the ether will not leak, thereby improving safety.

[0019] First, adjust the extension of the telescopic rod to make the lamp head reach the specified height, then turn on the switch to control the lamp head, and illuminate the construction location with the light emitted by the lamp head;

[0020] As the working time increases, the temperature of the lamp head gradually increases, and the temperature inside the lampshade also increases. Part of the heat in the lampshade is transferred to the sleeve through the heat conducting rod;

[0021] When the heat conducting rod transfers heat to the sleeve, the ether in the sleeve boils and turns into steam; at this time, the steam enters the guide tube located above the liquid surface, and the steam entering the guide tube contacts the heat conducting sheet and liquefies into small droplets;

[0022] At this time, the small droplets in the guide tube with the opening inclined upward will gather in the guide tube, so the weight of this part increases, and the small droplets in the guide tube with the opening inclined downward will flow out along the guide tube;

[0023] Therefore, the weight distribution on the left and right sides of the longitudinal section of the sleeve is uneven, so that the sleeve can rotate toward the heavier side, so that the sleeve can continue to rotate while the lamp head is working and heating up; thus, the scraper can be driven to move on the surface of the lens, and the dust attached to the surface of the lens can be scraped clean by the scraper, ensuring that the light emitted by the lamp head can be transmitted normally, thereby improving the lighting effect. Therefore, there is no need to replace the high-power lamp head, which reduces the power consumption of the battery, and can reduce the frequency of manual battery charging by the staff, thereby improving the convenience of work. Under the action of the air supply mechanism, the gas in the cavity is discharged through the air hole, so that the lens can be preliminarily cleaned before the scraper cleans the lens, thereby improving the cleaning effect of the lens, preventing a large amount of dust from entering the gap between the scraper and the lens, reducing the friction of the lens, and protecting the lens and ensuring that the light can be diffused normally. At the same time, under the action of the prompting mechanism, the staff can be prompted to transfer the frame, so that there is no need to increase the power of the lamp head during the construction process, thereby reducing the power consumption of the battery.

[0024] Furthermore, a sealing sleeve is fixedly mounted on the outer wall of the lens, and the sealing sleeve is movably mounted outside the sleeve. The sealing sleeve is used to prevent dust from entering the lampshade through a gap between the sleeve and the lens during the rotation of the sleeve.

[0025] Furthermore, the sealing sleeve is made of elastic material, and the air supply mechanism includes a pressurizing cavity evenly circumferentially opened on the sealing sleeve, and a through hole is opened on the side wall of the pressurizing cavity;

[0026] A small hole matching the through hole is provided on the side wall of the cavity;

[0027] The scraper includes a connecting plate and a shovel plate. The connecting plate is fixedly mounted on the side wall of the sleeve, and the shovel plate is fixedly mounted on the connecting plate. The cavity is opened on the shovel plate, and the side wall of the shovel plate is an arc shape that matches the outer ring side of the sealing sleeve.

[0028] Furthermore, a magnet is fixedly embedded on the shovel plate, a piston plate made of magnetic material is slidably installed in the pressurizing chamber, and the piston plate and the magnet attract each other, and an elastic member is installed between the side wall of the pressurizing chamber close to the sleeve and the piston plate.

[0029] When the shovel plate is away from the pressurized chamber, under the action of the elastic member, the piston plate is located at one end of the pressurized chamber close to the sleeve. When the sleeve drives the connecting plate to rotate, the end face of the shovel plate fits against the side wall of the sealing sleeve.

[0030] During the rotation of the shovel plate, the pressurized chamber gradually moves to the extension line of the shovel plate. During this process, the attraction between the magnet and the piston plate gradually increases. When the pressurized chamber is located on the extension line of the shovel plate, the small hole is connected with the through hole. At the same time, the piston plate is attracted and moves toward the direction close to the shovel plate. Therefore, the gas in the pressurized chamber will quickly pass through the through hole and the small hole into the cavity, which plays a role in supplying air to the cavity. The piston plate hits the sealing sleeve, and the impact force is transmitted to the shovel plate, which can then transmit the impact force to the dust attached to the surface of the shovel plate, shake off the dust, and automatically clean the shovel plate.

[0031] Furthermore, an elastic airbag is installed evenly around the inner wall of the lampshade, and heat dissipation openings are opened evenly around the side wall of the elastic airbag, and the heat dissipation openings correspond to the lamp caps one by one.

[0032] Furthermore, the heat conducting rod extends into the lampshade, and the heat conducting rod cooperates with the elastic airbag.

[0033] In the process of the sleeve driving the heat conducting rod to make circular motion, the heat conducting rod intermittently squeezes the elastic airbag. When the elastic airbag is squeezed, the gas in the elastic airbag is discharged through the heat dissipation port. The gas discharged from the heat dissipation port impacts the lamp head, thereby accelerating the air flow rate around the lamp head and making the high-temperature gas around the lamp head contact with the heat conducting rod, thereby improving the cooling effect on the lamp head, thereby preventing the increase of power consumption when the lamp head is working, and playing a role in saving electricity; at the same time, it can accelerate the rotation speed of the sleeve, shake off the dust attached to the scraper surface, and improve the cleaning effect of the lens.

[0034] Furthermore, the prompting mechanism includes a driving module arranged on the frame, and the driving module is used to drive the telescopic rod to rotate;

[0035] A human detection module and an alarm module are provided on the output end of the telescopic rod;

[0036] A distance detection module is provided on the lamp head;

[0037] The humanoid detection module sends the detected data to the driving module;

[0038] The distance detection module sends the detected data to the alarm module.

[0039] Furthermore, the driving module is a servo motor, the output end of the servo motor is fixedly connected to the telescopic rod, and the rotation angle of the output end of the servo motor is controlled by a program, which is a prior art and will not be described in detail.

[0040] The human shape detection module is used to detect the position of the staff and send the position data of the staff to the driving module, so that the servo motor drives the telescopic rod to rotate, so that the lamp head can automatically turn to the construction position of the staff; and the human shape detection module can adopt the human shape detection and tracking module used in the existing surveillance camera, which is the existing technology and will not be repeated;

[0041] The distance detection module is used to detect the distance between the staff and the frame, and send the measured data to the alarm module. The distance detection module is an ultrasonic distance measurement module. The ultrasonic distance measurement module is a prior art and will not be described in detail. By setting the distance detection module at the top of the telescopic rod, the influence of ground debris on the detection result can be reduced, thereby improving the accuracy of the detection.

[0042] The alarm module calculates the received data;

[0043]

[0044] D=d 实际 -d 灯

[0045] Where: L is the distance between the top of the telescopic rod and the worker detected by the distance detection module;

[0046] H is the height from the top of the telescopic rod to the ground, which is the preset value;

[0047] d 实际 is the distance between the staff and the frame, in meters;

[0048] d 灯 It is the distance between the farthest effective distance of the light emitted by the lamp head on the ground and the frame, which is the preset value in meters;

[0049] When D≥0, the alarm module works, prompting the staff to adjust the position of the frame so that the construction location can have sufficient light to ensure normal construction of the staff;

[0050] Under the cooperation of the human detection module, the driving module, the distance detection module and the alarm module, compared with increasing the lamp head power and expanding the irradiation range of the lamp head, by timely moving the lamp head to the vicinity of the construction location, the power consumption of the battery can be reduced, the number of charging times can be reduced, and the cost can be saved;

[0051] When D < 0, the alarm module does not work and the staff works normally.

[0052] Furthermore, a storage module and a display module are provided on the frame, and the display module is a display screen;

[0053] The alarm module sends the calculation result to the storage module. When D is less than 0, the storage module sorts the calculation data from small to large. For the sorting result, the maximum value of D is sent to the display module, and the display module displays the calculation result. A storage box is installed on the frame, and the storage box is used to load construction tools. Therefore, when the staff takes the construction tools, they can understand the distance between the farthest construction position and the lighting device through the display module, and then they can move the position of the lighting device when taking the construction tools, reducing the number of times the position of the lighting device is deliberately moved, that is, reducing the workload of the staff, and playing a role in improving work efficiency. Placing the construction tools in the storage box can prevent the loss of tools and facilitate the staff to take them, further improving work efficiency.

[0054] Compared with the prior art, the present invention has the following beneficial effects:

[0055] (1) This solution is provided with a sleeve, a driving mechanism, and a scraper; the scraper moves on the surface of the lens and scrapes off the dust attached to the surface of the lens, thereby ensuring that the light emitted by the lamp head can be transmitted normally and improving the lighting effect. Therefore, there is no need to replace the high-power lamp head, reducing the power consumption of the battery, and reducing the frequency of manual battery charging by the staff, thereby improving the convenience of work.

[0056] (2) This scheme is provided with a sealing sleeve, a shovel plate, a magnet, and a piston plate; the piston plate is attracted to move toward the shovel plate, so that the gas in the pressurized chamber will quickly pass through the through hole and the small hole into the cavity, playing the role of supplying air to the cavity, and the piston plate hits the sealing sleeve, and the impact force is transmitted to the shovel plate, which can then be transmitted to the dust attached to the surface of the shovel plate, shaking off the dust, playing the role of automatically cleaning the shovel plate, and ensuring that the light can be transmitted normally.

[0057] (3) This scheme is implemented by providing an elastic airbag and a heat-conducting rod. The heat-conducting rod intermittently squeezes the elastic airbag. When the elastic airbag is squeezed, the gas in the elastic airbag is discharged through the heat dissipation port. The gas discharged from the heat dissipation port impacts the lamp head, thereby accelerating the air flow rate around the lamp head and making the high-temperature gas around the lamp head contact with the heat-conducting rod, thereby improving the cooling effect on the lamp head and preventing the increase of power consumption when the lamp head is working, thus playing a role in saving electricity. At the same time, it can accelerate the rotation speed of the sleeve, shake off the dust attached to the scraper surface, and improve the cleaning effect on the lens.

[0068] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0069] Embodiment 1:

[0070] See also Figures 1 to 8An energy-saving lighting device for building construction comprises a frame 1, on which wheels 14 are provided, so as to facilitate pushing the frame 1, a telescopic rod 2 is rotatably mounted on the frame 1, and a plurality of lamp holders 3 are provided on the output end of the telescopic rod 2, and the lamp holders 3 can be driven to rotate by rotating the telescopic rod 2, thereby changing the irradiation direction of the lamp holders 3; a battery 4 for powering the lamp holders 3 is provided in the frame 1, and the lamp holders 3 are connected in series with the battery 4;

[0071] A mounting rod 5 is fixedly mounted on the output end of the telescopic rod 2, a lampshade 6 is detachably mounted on the mounting rod 5, and the lamp holder 3 is evenly mounted on the inner wall of the lampshade 6 in a circular manner;

[0072] A lens 7 is fixedly mounted on the surface of the lampshade 6, and the lens 7 is used to protect the lamp holder 3 and prevent dust from directly adhering to the surface of the lamp holder 3;

[0073] A sleeve 8 is inserted and rotatably mounted on the side wall of the lens 7, a scraper 9 for scraping the lens 7 is fixedly mounted on the side wall of the sleeve 8, and a driving mechanism for driving the sleeve 8 to rotate is disposed on the lampshade 6;

[0074] A solar panel 10 is provided on the mounting rod 5, and the solar panel 10 is used to charge the storage battery 4; therefore, when there is sufficient light, the staff can push the frame 1 into the sunlight to charge the storage battery 4 through the solar panel 10;

[0075] Among them, the solar panel 10 is used to charge the battery 4, which is a prior art and will not be described in detail.

[0076] A cavity 11 is formed on the scraper 9 , and an air hole 12 is formed on the side wall of the cavity 11 close to the lens 7 . An air supply mechanism for supplying air to the cavity 11 is provided on the mounting rod 5 , and a prompt mechanism cooperating with the lamp holder 3 is provided on the vehicle frame 1 .

[0077] The driving mechanism includes a guide tube 13 uniformly inserted on the inner wall of the sleeve 8, the guide tube 13 is located at the portion where the sleeve 8 extends outside the lampshade 6, a plurality of guide tubes 13 are uniformly distributed around the circumference, the number of the guide tubes 13 is at least 6, and the guide tubes 13 are arranged obliquely; the angle between the line between one end of the guide tube 13 close to the center of the longitudinal section of the sleeve 8 and the center of the longitudinal section of the sleeve 8 and the guide tube 13 is 60 degrees to 90 degrees;

[0078] The sleeve 8 is a heat-insulating sleeve, and an inner heat-conducting rod 15 extending into the lampshade 6 is embedded on the inner side wall of the sleeve 8 near one end of the lampshade 6, so that the heat generated by the lamp head 3 in the lampshade 6 during operation will be transferred to the inside of the sleeve 8 through the heat-conducting rod 15;

[0079] The flow guide pipe 13 is a heat preservation pipe, and a heat conducting sheet 16 extending to the outside of the sleeve 8 is embedded on the inner end wall of the flow guide pipe 13;

[0080] The sleeve 8 is filled with liquid, and the heat conducting sheet 16 is fixedly embedded in the sleeve 8. The liquid in the sleeve 8 is ether, and the liquid level in the sleeve 8 is below the horizontal plane where the center of the longitudinal section of the sleeve 8 is located. The sleeve 8 is in a sealed state, so the ether will not leak, thereby improving safety.

[0081] First, adjust the extension amount of the telescopic rod 2 so that the lamp head 3 reaches the specified height, then turn on the switch controlling the lamp head 3, and illuminate the construction position with the light emitted by the lamp head 3;

[0082] As the working time increases, the temperature of the lamp holder 3 gradually increases, and at this time the temperature inside the lampshade 6 also increases, and part of the heat inside the lampshade 6 is transferred to the sleeve 8 through the heat conducting rod 15;

[0083] When the heat conducting rod 15 transfers heat to the sleeve 8, the ether in the sleeve 8 boils and turns into steam; at this time, the steam enters the flow guide tube 13 located above the liquid surface, and the steam entering the flow guide tube 13 contacts the heat conducting sheet 16 and liquefies into small droplets;

[0084] At this time, the small droplets in the flow guide tube 13 with the opening inclined upward will gather in the flow guide tube 13, so the weight of this part increases, and the small droplets in the flow guide tube 13 with the opening inclined downward will flow out along the flow guide tube 13;

[0085] Therefore, the weight distribution on the left and right sides of the longitudinal section of the sleeve 8 is uneven, so that the sleeve 8 can rotate toward the heavier side, so that the sleeve 8 can continue to rotate during the operation and heating of the lamp head 3; thus, the scraper 9 can be driven to move on the surface of the lens 7, and the dust attached to the surface of the lens 7 can be scraped clean by the scraper 9, ensuring that the light emitted by the lamp head 3 can be transmitted normally, thereby improving the lighting effect. Therefore, there is no need to replace the high-power lamp head 3, which reduces the power consumption of the battery 4, and can reduce the frequency of manual charging of the battery 4 by the staff, thereby improving the convenience of work. Under the action of the air supply mechanism, the gas in the cavity 11 is discharged through the air hole 12, so that the lens 7 can be preliminarily cleaned before the scraper 9 cleans the lens 7, thereby improving the cleaning effect of the lens 7, preventing a large amount of dust from entering the gap between the scraper 9 and the lens 7, reducing the friction force on the lens 7, and protecting the lens 7 and ensuring that the light can be diffused normally. At the same time, under the action of the prompting mechanism, the staff can be prompted to transfer the frame 1, so that there is no need to increase the power of the lamp head 3 during the construction process, thereby reducing the power consumption of the battery 4.

[0086] like Figure 2 , Figure 5 , Figure 7 As shown, a sealing sleeve 17 is fixedly mounted on the outer wall of the lens 7, and the sealing sleeve 17 is movably sleeved outside the sleeve 8. The sealing sleeve 17 is used to prevent dust from entering the lampshade 6 through the gap between the sleeve 8 and the lens 7 during the rotation of the sleeve 8.

[0087] like Figure 2 , Figure 6 As shown, the sealing sleeve 17 is made of elastic material, and the air supply mechanism includes a pressurizing chamber 18 uniformly circumferentially opened on the sealing sleeve 17, and a through hole 19 is opened on the side wall of the pressurizing chamber 18;

[0088] A small hole 20 is provided on the side wall of the cavity 11 to match the through hole 19;

[0089] The scraper 9 includes a connecting plate 901 and a shovel plate 902 . The connecting plate 901 is fixedly mounted on the side wall of the sleeve 8 . The shovel plate 902 is fixedly mounted on the connecting plate 901 . The cavity 11 is opened on the shovel plate 902 . The side wall of the shovel plate 902 is an arc shape that matches the outer ring side of the sealing sleeve 17 .

[0090] A magnet 21 is fixedly embedded on the shovel plate 902, a piston plate 22 made of magnetic material is slidably installed in the pressurizing chamber 18, and the piston plate 22 and the magnet 21 attract each other, and an elastic member 23 is installed between the side wall of the pressurizing chamber 18 close to the sleeve 8 and the piston plate 22.

[0091] When the shovel plate 902 is away from the pressurizing chamber 18, under the action of the elastic member 23, the piston plate 22 is located at one end of the pressurizing chamber 18 close to the sleeve 8. When the sleeve 8 drives the connecting plate 901 to rotate, the end surface of the shovel plate 902 is in contact with the side wall of the sealing sleeve 17.

[0092] During the rotation of the shovel plate 902, the pressurized chamber 18 gradually moves to the extension line of the shovel plate 902. During this process, the attraction between the magnet 21 and the piston plate 22 gradually increases. When the pressurized chamber 18 is located on the extension line of the shovel plate 902, the small hole 20 is connected with the through hole 19; at the same time, the piston plate 22 is attracted and moves toward the direction close to the shovel plate 902, so the gas in the pressurized chamber 18 will quickly pass through the through hole 19 and the small hole 20 into the cavity 11, which plays a role in supplying air to the cavity 11, and the piston plate 22 hits the sealing sleeve 17, and the impact force is transmitted to the shovel plate 902, which can then transmit the impact force to the dust attached to the surface of the shovel plate 902, shake off the dust, and automatically clean the shovel plate 902.

[0093] like Figure 4 , Figure 7 As shown, an elastic air bag 24 is evenly installed on the inner side wall of the lampshade 6, and a heat dissipation opening is evenly opened on the side wall of the elastic air bag 24, and the heat dissipation opening corresponds to the lamp holder 3 one by one.

[0094] The heat conducting rod 15 extends into the lampshade 6 , and the heat conducting rod 15 cooperates with the elastic airbag 24 , and the heat conducting rod 15 is eccentrically arranged.

[0095] In the process of the sleeve 8 driving the heat conducting rod 15 to make a circular motion, the heat conducting rod 15 intermittently squeezes the elastic airbag 24. When the elastic airbag 24 is squeezed, the gas in the elastic airbag 24 is discharged through the heat dissipation port. The gas discharged from the heat dissipation port impacts the lamp holder 3, thereby accelerating the air flow rate around the lamp holder 3, making the high-temperature gas around the lamp holder 3 contact with the heat conducting rod 15, improving the cooling effect on the lamp holder 3, and then preventing the increase of power consumption when the lamp holder 3 is working, playing a role in saving electricity; at the same time, it can accelerate the rotation speed of the sleeve 8, shake off the dust attached to the surface of the scraper 9, and improve the cleaning effect on the lens 7.

[0096] like Figure 1 , Figure 2 , Figure 8 As shown, the prompt mechanism includes a driving module 25 disposed on the frame 1, and the driving module 25 is used to drive the telescopic rod 2 to rotate;

[0097] A human detection module 26 and an alarm module 27 are provided on the output end of the telescopic rod 2;

[0098] A distance detection module 28 is provided on the lamp head 3;

[0099] The human shape detection module 26 sends the detected data to the driving module 25;

[0100] The distance detection module 28 sends the detected data to the alarm module 27 .

[0101] The driving module 25 is a servo motor, the output end of the servo motor is fixedly connected to the telescopic rod 2, and the rotation angle of the output end of the servo motor is controlled by a program, which is a prior art and will not be described in detail.

[0102] The human shape detection module 26 is used to detect the position of the staff and send the position data of the staff to the driving module 25, so that the servo motor drives the telescopic rod 2 to rotate, so that the lamp head 3 can automatically turn to the construction position of the staff; and the human shape detection module 26 can adopt the human shape detection and tracking module used in the existing surveillance camera, which is the existing technology and will not be repeated;

[0103] The distance detection module 28 is used to detect the distance between the staff and the frame 1, and send the measured data to the alarm module 27, and the distance detection module 28 is an ultrasonic distance measurement module, which is a prior art and will not be described in detail; by setting the distance detection module 28 at the top of the telescopic rod 2, the influence of ground debris on the detection result can be reduced, thereby improving the accuracy of the detection;

[0104] The alarm module 27 calculates the received data;

[0105]

[0106] D=d 实际 -d 灯

[0107] Wherein: L is the distance between the top of the telescopic rod 2 and the staff member detected by the distance detection module 28;

[0108] H is the height from the top of the telescopic rod 2 to the ground, which is a preset value;

[0109] d 实际 is the distance between the staff and the frame 1, in meters;

[0110] d 灯 The distance between the farthest effective distance of the light emitted by the lamp head 3 on the ground and the frame 1 is a preset value in meters;

[0111] When D≥0, the alarm module 27 works, prompting the staff to adjust the position of the frame 1 so that the construction position can have sufficient light to ensure normal construction of the staff;

[0112] Under the cooperation of the human detection module 26, the driving module 25, the distance detection module 28 and the alarm module 27, compared with increasing the power of the lamp head 3 to expand the irradiation range of the lamp head 3, by timely moving the lamp head 3 to the vicinity of the construction location, the power consumption of the battery 4 can be reduced, the number of charging times can be reduced, and the cost can be saved;

[0113] When D<0, the alarm module 27 does not work and the staff works normally.

[0114] like Figure 1 As shown, a storage module 29 and a display module 30 are provided on the frame 1, and the display module 30 is a display screen;

[0115] And the alarm module 27 sends the calculation result to the storage module 29. When D is less than 0, the storage module 29 sorts the calculation data from small to large. For the sorting result, the maximum value of D is sent to the display module 30, and the display module 30 displays the calculation result. A storage box 31 is installed on the frame 1, and the storage box 31 is used to load construction tools. Therefore, when the staff takes the construction tools, they can understand the distance between the farthest construction position and the lighting device through the display module 30, and then they can move the position of the lighting device when taking the construction tools, which reduces the number of times the lighting device position is deliberately moved, that is, it reduces the workload of the staff, and plays a role in improving work efficiency. And placing the construction tools in the storage box 31 can prevent the loss of tools and facilitate the staff to take them, which further improves work efficiency.

[0116] The above is only a preferred specific implementation of the present invention; however, 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 solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
