Description

Technical Field

[0001] This application belongs to the technical field of billboards, and particularly relates to an LED advertising light sign device. Background Technology

[0002] LED light billboards are used for shop fronts, company signs, and advertising. The billboards are equipped with LED lights, power supply components, and control systems, allowing posters to be displayed and advertised at night. Some billboards even have LED lights that flash to enhance the display effect. Some billboards also have solar panels installed on top to save power, and this technology is widely used.

[0003] A Chinese patent with publication number CN112309278B discloses an automatic cleaning solar LED advertising light sign device, which includes a display board and a water bladder mechanism. The top of the display board is provided with a crystalline silicon plate, the top right side is provided with a motor, and the bottom right side is provided with a bearing seat. A screw is installed between the bearing seat and the motor. A sweeping rod is installed on the front side of the display board, and the right end of the sweeping rod is engaged with the screw. When the screw rotates, it carries the sweeping rod to slide upward and downward, so that the sweeping rod completes the wiping action from top to bottom on the front surface of the display board.

[0004] While the aforementioned advertising light signs can clean solar panels, the water used for cleaning needs to be transported from elsewhere and cannot be directly collected from rainwater. Improvements are needed to address this issue. Summary of the Invention

[0005] The purpose of this application is to address the aforementioned technical problems by providing an LED advertising light sign that can achieve efficient cleaning of solar panels and save water.

[0006] This application provides an LED advertising light sign, including a light sign body and a solar panel, wherein the light sign body includes:

[0007] A water collection tank, located on top of the sign body, is used to collect rainwater, and the water collection tank is equipped with a water trough;

[0008] An adjustment component, which is installed and connected to the solar panel and used to move and adjust the solar panel;

[0009] The filter plate is placed in the water collection tank and is used to filter the water collected in the water collection tank.

[0010] A wiping assembly for wiping the surface of a solar panel, the wiping assembly being provided with foam;

[0011] A water delivery assembly is used to deliver water from a water tank to a wiping assembly, the water delivery assembly including a water pump and a connecting pipe;

[0012] The connecting pipe is connected to the foam, and two sets of solar panels are provided.

[0013] The water collection tank is located on top of the sign. When it rains, rainwater is collected through a trough. Solar panels are mounted on the collection tank via an adjustable assembly. When the assembly retracts, the solar panels close the opening of the collection tank, placing them parallel to the ground. This maximizes power generation efficiency when the sun is directly overhead. In the morning or evening, the tilt angle of the solar panels can be adjusted using the assembly to further improve efficiency. Opening the solar panels allows the trough to collect rainwater, which is then filtered. The water plate filters the water flowing into the water tank, and the clean water flows to the bottom of the water collection tank. The water in the water collection tank is transported through the water delivery component. A water pump draws water from the bottom of the water collection tank and transports it through a connecting pipe to the foam of the wiping component. The water moistens the dry and clumps of dust on the solar panel, and the dust is removed after wiping with the foam. By setting up two sets of solar panels, when the solar panels are arranged in an inverted V-shape, the efficiency of rainwater collection can be improved. The foam can reduce scratches and wear on the surface of the solar panels.

[0014] Furthermore, the wiping assembly includes:

[0015] The first motor is used for moving the foam.

[0016] The first lead screw is connected to the first motor;

[0017] A movable seat is adapted to the first lead screw, and the movable seat is installed and connected to the wiping assembly;

[0018] The drive cylinder is used to drive the first motor, the first lead screw, the moving seat, and the foam lifting mechanism;

[0019] A cleaning brush, placed in a water tank, is used to remove dirt from the foam.

[0020] The wiping assembly is driven by a first motor to rotate a first lead screw. The first lead screw is connected to a movable seat by a thread, allowing the movable seat to move along the first lead screw, thus cleaning the surface of the solar panel with foam. The foam is raised and lowered by a drive cylinder to adapt to the closed or open state of the solar panel. The foam comes into contact with the cleaning brush, and then the first motor drives the cleaning brush to move back and forth. The friction between the cleaning brush and the foam removes the dust adhering to the foam. When the solar panel is closed, the foam retracts into the water collection tank by the drive cylinder.

[0021] Furthermore, the adjustment component includes:

[0022] The support frame is placed in the water collection tank and connected between the two opposite inner walls of the water tank;

[0023] The mounting bracket is placed on the support frame;

[0024] An adjusting rod is corresponding to and movably connected to the mounting bracket, and the adjusting rod is movably connected to the solar panel.

[0025] The second motor is mounted on the support frame;

[0026] The winding reel is mounted on the output shaft of the second motor;

[0027] The connecting rope connects the take-up reel to the adjusting rod;

[0028] The first spring is placed between the adjusting rod and the solar panel;

[0029] The solar panel has several support frames, and two mounting frames for the same solar panel are placed on the same support frame. The mounting frame is equipped with a limiting post that is compatible with the adjusting rod.

[0030] The support frame is connected between the two opposite inner walls of the water tank. The mounting frame is placed on the support frame. The two ends of the adjusting rod are hinged to the mounting frame and the solar panel. When the second motor drives the winding wheel to rotate, the adjusting rod is pulled by the connecting rope to make the adjusting rod parallel to the axis of the mounting frame, thereby raising the solar panel and opening the water tank. When the winding wheel rotates in the opposite direction, the connecting rope is unwound, and the solar panel is pulled back to its original position by the first spring. The rotation angle of the adjusting rod is limited by the limit post to prevent the included angle from being reversed.

[0031] Furthermore, the adjustment component also includes:

[0032] The third motor is mounted on the support frame;

[0033] The second lead screw is mounted on the output shaft of the third motor;

[0034] An adjusting seat is installed and connected to the mounting bracket. The adjusting seat is placed on the support frame and is adapted to the second lead screw.

[0035] The adjusting wheel is hinged to the inner adjusting rod and connected to the connecting rope;

[0036] The detection component is positioned between two corresponding adjusting rods;

[0037] A torsion spring is placed between the adjusting wheel and the adjusting rod to reset the adjusting wheel after it rotates.

[0038] A locking mechanism is used for locking the adjusting wheel and the adjusting rod, as well as locking the adjusting rod and the mounting bracket.

[0039] The support frame and mounting frame are equipped with guide wheels that are compatible with the connecting rope.

[0040] A third motor drives a second lead screw to rotate. The adjusting seat is threadedly connected to the second lead screw. Each mounting bracket corresponds to an individual adjusting seat. When the outermost adjusting seat moves, the corresponding adjusting rod forms an angle with the axis of the mounting bracket, while the other adjusting rod remains parallel to the axis of the mounting bracket, causing the solar panel to deflect outwards. When the innermost adjusting seat moves, the corresponding adjusting rod forms an angle with the axis of the mounting bracket, while the other adjusting rod remains parallel to the axis of the mounting bracket, causing the solar panel to deflect inwards. When the solar panels deflect in the same direction simultaneously, the third motor driving one solar panel corresponds to the inner adjusting rod, and the other solar panel... The third motor driving the solar panel corresponds to the outer adjusting rod. At this time, the deflection of the solar panel can improve the power generation efficiency. When the solar panel deflects inward at the same time, the adjusting seat corresponding to the adjusting rod near the inner side moves, which can improve the rainwater collection efficiency. When the solar panel is in this state of tilting, wiping can make the used water flow back into the water tank, realizing the recycling of water resources and saving water. When the adjusting rod near the inner side rotates, the connecting rope is unwound from the adjusting wheel through the adjusting wheel and locking mechanism to prevent the connecting rope from breaking. The torsion spring facilitates the reset of the adjusting wheel, the guide wheel guides the connecting rope, and the detection component is used to detect the deflection angle of the solar panel.

[0041] Furthermore, the detection component includes:

[0042] The outer casing is hinged to one of the adjusting rods;

[0043] The inner housing is hinged to another corresponding adjusting rod, and the inner housing is movably connected to the outer housing;

[0044] The second spring is placed between the outer shell and the inner shell, and on both sides of the inner shell;

[0045] The contact coil is wound around the outer surface of the inner housing;

[0046] The contacts, which abut against the contact coil, are used to connect the current, and the contacts are located on the inner wall surface of the housing.

[0047] The outer shell is provided with a telescopic hole that is adapted to the inner shell, and the inner shell is provided with an abutting part that abuts against the second spring.

[0048] The inner shell is placed inside the outer shell. When the solar panel deflects, the inner shell moves inside the outer shell and along the axial direction, causing the contact position between the contact point and the contact coil to move relative to each other, thereby changing the resistance of the contact coil and causing a change in the current. This allows the deflection angle of the solar panel to be calculated. The inner shell extends outward through the telescopic hole to hinge with the adjusting rod. The abutment part abuts against the second spring, so that the two adjusting rods are parallel to each other without any force.

[0049] Furthermore, the locking mechanism includes:

[0050] The clutch seat is mounted on the adjusting rod and located on one side of the adjusting wheel;

[0051] The clutch chamber is located on the adjusting rod;

[0052] The first piston is placed in the clutch chamber and is installed and connected to the clutch seat;

[0053] The first tooth is placed on the clutch seat;

[0054] The second tooth is placed on the adjusting wheel and is adapted to the first tooth;

[0055] The first electromagnet is installed in the clutch cavity;

[0056] The second electromagnet is mounted on the first piston and corresponds to the first electromagnet.

[0057] A return spring is used to control the first piston to be positioned in the middle of the clutch chamber;

[0058] The locking tongue is positioned on the adjusting rod;

[0059] The locking tongue is respectively placed on two adjusting rods. The mounting bracket is provided with a locking hole adapted to the locking tongue. The adjusting rod is provided with a locking cavity. The locking cavity is provided with a second piston. The second piston is provided with a telescopic column. The locking tongue is provided with a telescopic groove adapted to the telescopic column. A third spring is provided between the locking tongue and the second piston. The locking cavities on the two adjusting rods are respectively connected to the two ends of the clutch cavity.

[0060] The clutch seat moves within the clutch cavity via the first and second electromagnets. When the adjusting wheel needs to be locked, the first and second teeth on the clutch seat engage to lock the adjusting wheel. At this time, the space near the adjusting wheel in the clutch cavity is compressed, causing the locking tongue in the locking cavity connected to it to extend. This locking tongue is located on the adjusting rod near the inner side, allowing it to engage with the lock hole and keep the corresponding adjusting rod and mounting bracket locked, ensuring stable deflection of the solar panel. When the adjusting rod corresponding to the adjusting wheel rotates, the first and second electromagnets are controlled to unlock the adjusting wheel, and the corresponding locking tongue extends, locking the adjusting rod near the outer side and mounting bracket, ensuring stable deflection of the solar panel. The extension and retraction of the locking tongue is achieved by the movement of the second piston in the locking hole. The flexibility of the locking tongue during extension and retraction is improved and rigid compression is reduced by the telescopic column, telescopic groove, and third spring. When the first and second electromagnets do not interact, the first piston is placed in the middle position of the clutch cavity under the action of the return spring, thereby controlling the locking tongues on both adjusting rods to not engage with the lock hole.

[0061] Furthermore, the wiping assembly also includes:

[0062] The fourth motor is mounted on the movable base;

[0063] The first gear is mounted on the output shaft of the fourth motor;

[0064] The second gear is adapted to the first gear and is connected to the foam.

[0065] The limiting seat is movably mounted on the movable seat;

[0066] The fifth motor is mounted on the limit seat;

[0067] The third gear is mounted on the output shaft of the fifth motor;

[0068] The rack is arc-shaped and its axis is the same as that of the first lead screw. The rack is adapted to the third gear.

[0069] The pressure sensor is placed on the limit seat.

[0070] The fifth motor is electrically connected to the contact coil and contacts.

[0071] The fourth motor, the first gear, and the second gear are used to drive the foam to rotate and move. When it comes into contact with the pressure sensor on the limit seat, the foam is positioned. The fifth motor, the third gear, and the rack control the limit seat to move to the required position. The drive of the fifth motor is calculated by the current on the contact coil.

[0072] Furthermore, the specific steps of the solar panel deflection process include:

[0073] S1, start the second motor to make the connecting rope pull the adjusting rod, so that the solar panel moves horizontally upward;

[0074] S2, control the solar panels to deflect in the same direction. Of the two sets of solar panels, one set of solar panels is driven by the second motor to move the mounting frame with the adjustment wheel, and the other set of solar panels is driven by the second motor to move the mounting frame without the adjustment wheel.

[0075] S3 controls the solar panel to deflect so that the inner side moves downward, and drives the mounting bracket with the corresponding adjusting wheel to move via the second motor.

[0076] When the solar panels are tilted in the same direction, they can receive sunlight better. When the solar panels are tilted inward, they can improve the efficiency of rainwater collection. At the same time, wiping the surface of the solar panels makes it easier for water to flow back into the water tank, realizing the recycling of water resources and improving water conservation.

[0077] The beneficial effects of this application are:

[0078] 1. By adjusting the tilt angle of the solar panels using the adjustment components, the efficiency of solar power generation is improved. The solar panels are opened by adjusting the components, allowing the water tank to collect rainwater. The collected rainwater is filtered through the filter plate, and the clean water flows to the bottom of the water collection tank.

[0079] 2. Water in the water collection tank is transported through the water delivery component. Water is drawn from the bottom of the water collection tank by a water pump and transported through a connecting pipe to the foam of the wiping component. The water moistens the dry and clumps of dust on the solar panel, and the dust is removed by wiping with the foam.

[0080] 3. The foam comes into contact with the cleaning brush, and then the first motor drives the cleaning brush to move back and forth. The dust adhering to the foam is brushed off by the friction between the cleaning brush and the foam. When the solar panel closes, the foam is retracted into the water collection tank by the drive cylinder.

[0081] 4. When the solar panels deflect in one direction simultaneously, the third motor driving one solar panel corresponds to the inner adjustment rod, and the third motor driving the other solar panel corresponds to the outer adjustment rod. This deflection of the solar panels can improve power generation efficiency. When the solar panels deflect inward simultaneously, the adjustment seat corresponding to the adjustment rod closer to the inner side moves, which can improve the rainwater collection efficiency.

All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0093] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more.

[0094] The embodiments of this application are described in detail below with reference to the accompanying drawings, through specific examples and application scenarios.

[0095] Example 1:

[0096] like Figures 1-3 As shown, this application embodiment provides an LED advertising light sign, including a light sign body 100 and a solar panel 200. The light sign body 100 includes:

[0097] A water collection tank 300 is placed on top of the light sign body 100 and is used to collect rainwater. The water collection tank 300 is equipped with a water holding trough 310.

[0098] Adjustment component 400 is installed and connected to solar panel 200 and is used to move and adjust solar panel 200;

[0099] The filter plate 320 is placed in the water collection tank 300 and is used to filter the water collected by the water collection tank 300.

[0100] Wiping assembly 500 is used to wipe the surface of solar panel 200, and the wiping assembly 500 is provided with foam 510;

[0101] A water delivery assembly is used to deliver water from the water tank 310 to the wiping assembly 500. The water delivery assembly includes a water pump 301 and a connecting pipe.

[0102] The connecting pipe is connected to the foam 510, and two sets of solar panels 200 are provided.

[0103] A water collection tank 300 is placed on top of the sign body 100. When it rains, rainwater is collected through a water trough 310. A solar panel 200 is installed on the water collection tank 300 via an adjustment component 400. When the adjustment component 400 retracts, the solar panel 200 closes the opening of the water collection tank 300, making the solar panel 200 parallel to the ground. The solar power generation efficiency is highest when the sun is directly overhead. In the morning or evening, the tilt angle of the solar panel 200 can be adjusted using the adjustment component 400 to improve the solar power generation efficiency. Opening the solar panel 200 via the adjustment component 400 allows the water trough 310 to collect rainwater. The collected rainwater is then... The filter plate 320 filters the water flowing into the water tank 310. The clean water flows to the bottom of the water collection tank 300. The water in the water collection tank 300 is transported through the water conveying component. The water pump 301 draws water from the bottom of the water collection tank 300 and transports it through the connecting pipe to the foam 510 of the wiping component 500. The water moistens the dry and clumps of dust on the solar panel 200. The dust is then removed by wiping with the foam 510. By setting up two sets of solar panels 200, when the solar panels 200 are arranged in an inverted V-shape, the efficiency of rainwater collection can be improved. The foam 510 can reduce the scratching and wear on the surface of the solar panel 200.

[0104] Example 2:

[0105] like Figure 2 As shown, this application embodiment provides an LED advertising light sign, which, in addition to including the above-mentioned technical features, further includes the wiping component 500 comprising:

[0106] The first motor 520 is used to move the foam 510;

[0107] The first lead screw 530 is connected to the first motor 520;

[0108] The movable seat 540 is adapted to the first lead screw 530, and the movable seat 540 is installed and connected to the wiping assembly 500;

[0109] The drive cylinder 501 is used to drive the first motor 520, the first lead screw 530, the moving seat 540, and the foam 510 to lift and lower.

[0110] Cleaning brush 502, placed in water tank 310, is used to remove dirt from foam 510.

[0111] The wiping assembly 500 is driven by the first motor 520 to rotate the first lead screw 530. The first lead screw 530 is connected to the movable seat 540 by a thread, so that the movable seat 540 moves along the first lead screw 530, so that the foam 510 cleans the surface of the solar panel 200. The foam 510 is raised and lowered by the drive cylinder 501 to adapt to the closed or open state of the solar panel 200. The foam 510 contacts the cleaning brush 502, and then the first motor 520 drives the cleaning brush 502 to move back and forth. The dust adhering to the foam 510 is brushed off by the friction between the cleaning brush 502 and the foam 510. When the solar panel 200 is closed, the foam 510 is retracted into the water collection tank 300 by the drive cylinder 501.

[0112] Example 3:

[0113] like Figure 3 As shown, this application embodiment provides an LED advertising light sign, which, in addition to including the above-mentioned technical features, further includes the following adjustment component 400:

[0114] The support frame 410 is placed in the water collection tank 300 and connected between two opposite inner side walls of the water holding tank 310.

[0115] Mounting bracket 420 is placed on support bracket 410;

[0116] Adjusting rod 430 corresponds to and is movably connected to mounting bracket 420, and adjusting rod 430 is movably connected to solar panel 200;

[0117] The second motor 401 is mounted on the support frame 410;

[0118] The winding reel 402 is mounted on the output shaft of the second motor 401;

[0119] The connecting rope 403 is connected between the winding reel 402 and the adjusting rod 430;

[0120] The first spring 440 is positioned between the adjusting rod 430 and the solar panel 200;

[0121] The solar panel 200 has several support frames 410, and the same solar panel 200 has two mounting frames 420 placed on the same support frame 410. The mounting frame 420 is equipped with a limiting post 421 that is adapted to the adjusting rod 430.

[0122] The support frame 410 is connected between the two opposing inner walls of the water tank 310. The mounting frame 420 is placed on the support frame 410. The two ends of the adjusting rod 430 are hinged to the mounting frame 420 and the solar panel 200. When the second motor 401 drives the winding wheel 402 to rotate, the connecting rope 403 pulls the adjusting rod 430 so that the adjusting rod 430 is parallel to the axis of the mounting frame 420, thereby raising the solar panel 200 and opening the water tank 310. When the winding wheel 402 rotates in the opposite direction, the connecting rope 403 unwinds, and the first spring 440 pulls the solar panel 200 back to its original position. The limiting post 421 limits the rotation angle of the adjusting rod 430 to prevent the included angle from being reversed.

[0123] Furthermore, the adjustment component 400 also includes:

[0124] The third motor 450 is mounted on the support frame 410;

[0125] The second lead screw 451 is mounted on the output shaft of the third motor 450;

[0126] An adjusting seat 452 is installed and connected to the mounting bracket 420. The adjusting seat 452 is placed on the support bracket 410 and is adapted to the second lead screw 451.

[0127] The adjusting wheel 460 is hinged to the inner adjusting rod 430 and connected to the connecting rope 403;

[0128] The detection component 470 is positioned between two corresponding adjusting rods 430;

[0129] Torsion spring 461 is placed between adjusting wheel 460 and adjusting rod 430, and is used to reset the adjusting wheel 460 after it rotates.

[0130] The locking mechanism 600 is used for locking the adjustment wheel 460 and the adjustment rod 430, and for locking the adjustment rod 430 and the mounting bracket 420.

[0131] The support frame 410 and the mounting frame 420 are equipped with guide wheels 404 that are compatible with the connecting rope 403.

[0132] The third motor 450 drives the second lead screw 451 to rotate. The adjusting seat 452 is threadedly connected to the second lead screw 451. Each mounting bracket 420 corresponds to an adjusting seat 452. When the outer adjusting seat 452 moves, the axis between the corresponding adjusting rod 430 and the mounting bracket 420 forms an angle, while the other adjusting rod 430 remains parallel to the axis of the mounting bracket 420, causing the solar panel 200 to deflect outward. When the inner adjusting seat 452 moves, the axis between the corresponding adjusting rod 430 and the mounting bracket 420 forms an angle, while the other adjusting rod 430 remains parallel to the axis of the mounting bracket 420, causing the solar panel 200 to deflect inward. When the solar panels 200 deflect in one direction simultaneously, the third motor 450 driving one solar panel 200 corresponds to the inner adjusting rod 430, while the other... The third motor 450 driving the solar panel 200 corresponds to the outer adjusting rod 430. When the solar panel 200 deflects, it can improve the power generation efficiency. When the solar panel 200 deflects inward at the same time, it moves the adjusting seat 452 corresponding to the adjusting rod 430 near the inner side, which can improve the rainwater collection efficiency. When the solar panel 200 is in this state of tilting, it can be wiped, and the used water can flow back into the water tank 310, realizing the recycling of water resources and saving water. When the adjusting rod 430 near the inner side rotates, the connecting rope 403 is unwound from the adjusting wheel 460 through the adjusting wheel 460 and the locking mechanism 600 to prevent the connecting rope 403 from breaking. The torsion spring 461 facilitates the reset of the adjusting wheel 460. The guide wheel 404 guides the connecting rope 403. The detection component 470 is used to detect the deflection angle of the solar panel 200.

[0133] Example 4:

[0134] like Figure 4 As shown, this application embodiment provides an LED advertising light sign, which, in addition to including the above-mentioned technical features, further includes the detection component 470 comprising:

[0135] The outer casing 471 is hinged to one of the adjusting rods 430;

[0136] The inner housing 472 is hinged to another corresponding adjusting rod 430, and the inner housing 472 is movably connected to the outer housing 471;

[0137] The second spring 473 is placed between the outer shell 471 and the inner shell 472, and is located on both sides of the inner shell 472;

[0138] Contact coil 474 is wound around the outer surface of inner housing 472;

[0139] Contact 475 abuts against contact coil 474 and is used to connect current. Contact 475 is located on the inner wall surface of housing 471.

[0140] The outer shell 471 is provided with a telescopic hole 476 adapted to the inner shell 472, and the inner shell 472 is provided with an abutment part 477 that abuts against the second spring 473.

[0141] The inner housing 472 is placed inside the outer housing 471. When the solar panel 200 deflects, the inner housing 472 moves inside the outer housing 471 and moves along the axial direction, causing the contact position between the contact point 475 and the contact coil 474 to move relative to each other, thereby changing the resistance of the contact coil 474 and causing the current to change. This allows the deflection angle of the solar panel 200 to be calculated. The inner housing 472 extends outward through the telescopic hole 476 to hinge with the adjusting rod 430. The abutment part 477 abuts against the second spring 473, so that the two adjusting rods 430 are parallel to each other without the action of force.

[0142] Example 5:

[0143] like Figure 3 , Figure 5 , Figure 6 As shown, this application embodiment provides an LED advertising light sign, which, in addition to including the above-mentioned technical features, further includes the locking mechanism 600 comprising:

[0144] The clutch seat 610 is mounted on the adjusting rod 430 and is located on one side of the adjusting wheel 460;

[0145] The clutch chamber 620 is positioned on the adjusting rod 430;

[0146] The first piston 630 is placed in the clutch chamber 620 and is installed and connected to the clutch seat 610;

[0147] The first tooth 611 is placed on the clutch seat 610;

[0148] The second tooth 462 is placed on the adjusting wheel 460 and is adapted to the first tooth 611;

[0149] The first electromagnet 640 is installed in the clutch cavity 620;

[0150] The second electromagnet 641 is mounted on the first piston 630 and corresponds to the first electromagnet 640.

[0151] The return spring 650 is used to control the first piston 630 to be placed in the middle position of the clutch chamber 620;

[0152] Locking tongue 660 is placed on adjusting rod 430;

[0153] The locking tongue 660 is respectively placed on two adjusting rods 430. The mounting bracket 420 is provided with a locking hole 422 adapted to the locking tongue 660. The adjusting rod 430 is provided with a locking cavity 670. The locking cavity 670 is provided with a second piston 680. The second piston 680 is provided with a telescopic column 681. The locking tongue 660 is provided with a telescopic groove 661 adapted to the telescopic column 681. A third spring 690 is provided between the locking tongue 660 and the second piston 680. The locking cavities 670 on the two adjusting rods 430 are respectively connected to both ends of the clutch cavity 620.

[0154] The clutch seat 610 is controlled to move within the clutch cavity 620 by the first electromagnet 640 and the second electromagnet 641. When it is necessary to keep the adjusting wheel 460 locked, the first tooth 611 on the clutch seat 610 engages with the second tooth 462 to lock the adjusting wheel 460. At this time, the space near the adjusting wheel 460 in the clutch cavity 620 is compressed, causing the locking tongue 660 in the locking cavity 670 connected to it to extend. The locking tongue 660 is located on the adjusting rod 430 near the inner side, so that the locking tongue 660 engages with the lock hole 422, keeping the corresponding adjusting rod 430 and the mounting bracket 420 in a locked state, ensuring the stable deflection of the solar panel 200. When the adjusting rod 430 corresponding to the adjusting wheel 460 rotates, the first electromagnet 610 is controlled to move within the clutch cavity 620. The first electromagnet 640 and the second electromagnet 641 unlock the adjusting wheel 460, and the corresponding locking tongue 660 extends, locking the adjusting rod 430 near the outside to the mounting bracket 420, ensuring the stable deflection of the solar panel 200. The extension and retraction of the locking tongue 660 is achieved by the movement of the second piston 680 in the locking hole. The extension and retraction of the locking tongue 660 is improved by the extension column 681, the extension groove 661, and the third spring 690, and the rigid compression is reduced. When the first electromagnet 640 and the second electromagnet 641 do not interact, the first piston 630 is placed in the middle position of the clutch cavity 620 under the action of the return spring 650, thereby controlling the locking tongue 660 on the two adjusting rods 430 to not cooperate with the locking hole 422.

[0157] The fourth motor 550 is mounted on the movable base 540;

[0158] The first gear 551 is mounted on the output shaft of the fourth motor 550;

[0159] The second gear 552 is adapted to the first gear 551 and is connected to the foam 510;

[0160] The limiting seat 560 is movably mounted on the movable seat 540;

[0161] The fifth motor 561 is mounted on the limit seat 560;

[0162] The third gear 562 is mounted on the output shaft of the fifth motor 561;

[0163] The rack 563 is arc-shaped and its axis is the same as that of the first lead screw 530. The rack 563 is adapted to the third gear 562.

[0164] Pressure sensor 564 is placed on limit seat 560.

[0165] The fifth motor 561 is electrically connected to the contact coil 474 and the contact 475.

[0166] The fourth motor 550, the first gear 551, and the second gear 552 are used to drive the foam 510 to rotate and move. When it comes into contact with the pressure sensor 564 on the limit seat 560, the position of the foam 510 is positioned. The fifth motor 561, the third gear 562, and the rack 563 are used to control the limit seat 560 to move to the required position. The drive of the fifth motor 561 is calculated by the current on the contact coil 474.

[0167] Example 7:

[0168] like Figure 9 As shown, this application embodiment provides an LED advertising light sign, which, in addition to including the above-mentioned technical features, further includes the following specific steps in the deflection process of the solar panel 200:

[0169] S1, start the second motor 401, so that the connecting rope 403 pulls the adjusting rod 430, so that the solar panel 200 moves horizontally upward;

[0170] S2, control the solar panels 200 to deflect in the same direction. Of the two sets of solar panels 200, one set of solar panels 200 is driven by the second motor 401 to move the mounting frame 420 corresponding to the adjusting wheel 460, and the other set of solar panels 200 is driven by the second motor 401 to move the mounting frame 420 corresponding to the one without the adjusting wheel 460.

[0171] S3, control the solar panel 200 to deflect so that the inner side moves downward, and drive the mounting bracket 420 with the corresponding adjusting wheel 460 to move through the second motor 401.

[0172] When the solar panel 200 is controlled to deflect in the same direction, it is used to better receive sunlight. When the solar panel 200 is controlled to deflect inward, it improves the efficiency of rainwater collection. At the same time, wiping the surface of the solar panel 200 makes it easier for water to flow back into the water tank 310, realizing the recycling of water resources and improving water conservation.
