Description

Technical Field

[0001] The invention relates to the technical field of mast mechanisms, in particular to a mast mechanism capable of autonomously adjusting a lamp holder angle by detecting an environment. Background Art

[0002] In order to achieve the purpose of lighting, lamp holders are usually installed on masts. However, masts are generally long and easily affected by external wind, which causes the lamp holders to shake. The lamp holders are also easily affected by external dust, which reduces the service life of the lamp holders. Therefore, at present, there are mainly the following problems in installing lamp holders on masts: (1) The fixed clamping method is not convenient for adjusting the position next time; (2) There is no guide structure, and the lamp holder shakes for a long time, which brings adverse effects; (3) There is no internal dust removal mechanism, which reduces the service life. Summary of the invention

[0003] The object of the present invention is to provide a mast mechanism that detects the environment and autonomously adjusts the angle of a lamp holder, so as to solve the problems raised in the above-mentioned background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: including a lamp holder, a clamping mechanism is installed on the lamp holder, a pressurizing mechanism is installed on one side of the clamping mechanism, the pressurizing mechanism is connected to a dust removal box through a pipeline, the dust removal box is installed on the lamp holder, an identification mechanism is installed below the pressurizing mechanism, a lighting lamp is installed on one side of the identification mechanism, a guide cover is installed on one side of the lighting lamp, the clamping mechanism is used to clamp the mast, the pressurizing mechanism is used to pressurize the clamping mechanism and the dust removal box, the dust removal box is used to remove dust from the lamp holder, the adjustment mechanism adjusts the angle of the guide cover, and the identification mechanism is used to detect wind direction.

[0005] A partition is installed on the lamp holder, and the clamping mechanism is installed above the partition. The clamping mechanism includes a cam A. A driving motor is vertically installed on the lamp holder, and the cam A is installed on the output shaft of the driving motor. A driving disk is concentrically installed below the cam A, and a pawl A is rotatably installed on the driving disk. An electromagnet A is installed on one side of the pawl A. A driving gear is installed on the outer side of the driving disk, and a first ratchet tooth shape is arranged on the upper middle layer of the driving gear. The lower middle layer of the driving gear is installed on the output shaft of the driving motor through a bearing. A transmission belt is meshed on the outer side of the driving gear, and a driven gear B and a driven gear C are meshed on the inner side of the transmission belt. The driven gear B and the driven gear C are mirror-imaged, and the driven gears B and C are both installed on the partition through bearings. A cam B is installed above the driven gear B, and a cam C is installed above the driven gear C. A pushing mechanism is installed on one side of the cam B and the cam C.

[0006] The pushing mechanism includes a pushing plate A, a fixed plate is installed on the partition, a reciprocating rod A is slidably installed on the fixed plate, the pushing plate A is installed on one end of the reciprocating rod A, a return spring is installed on the reciprocating rod A, one end of the return spring is installed on the fixed plate, the other end of the return spring is installed on the reciprocating rod A, a positioning block A is installed on the other end of the reciprocating rod A, the positioning block A is hollow inside, a negative pressure port is provided on the positioning block A, the outer side of the positioning block A is made of rubber, a first control valve is installed on the negative pressure port, and the first control valve is connected to the pressurizing mechanism through a pipeline.

[0007] Press the start button on the control panel, the device is powered on, and the staff will place the device at the corresponding position of the mast. The clamping mechanism will start to work and lock the device on the mast. After that, the identification mechanism will identify the wind direction and adjust the angle of the air guide cover according to the wind direction to reduce the adverse effects of the wind on the lighting. The dust removal box, positioning block A, and air guide cover will be pressurized or negatively pressurized by the pressurizing mechanism.

[0008] The working process of the clamping mechanism is as follows: the driving motor drives the active disk to rotate, and the electromagnet A is energized (all the electromagnets mentioned below are push-pull electromagnets, and the telescopic rod is a reciprocating component on the electromagnet). The telescopic rod on the electromagnet A pushes the pawl A to engage with the first ratchet gear, that is, the active disk drives the active gear to rotate synchronously, and the active gear drives the driven gear B and the driven gear C to rotate synchronously through the transmission belt. The driven gear B and the driven gear C respectively drive the cam B and the cam C to rotate, and the cam B and the cam C both drive the pushing mechanism to move. The specific working process of the pushing mechanism is as follows: Bottom: When one side of cam B or cam C moves to the maximum push stroke, cam B will push the push plate A to move, and the push plate A will push the reciprocating rod A to move on the fixed plate. At the same time, the reciprocating rod A compresses the reset spring, and the reciprocating rod A drives the positioning block A to contact the outer surface of the mast. Under the joint action of cam B and cam C, the positioning blocks A on both sides clamp the mast to form the first repositioning clamping, and adsorb the mast through the negative pressure port on the positioning block A (see the negative pressure adsorption process below) to form the second repositioning clamping. The above double positioning process ensures the reliability of mast clamping;

[0009] The pressurization working process is as follows: the driving gear drives cam A to rotate. When one side of cam A moves to the maximum push stroke, cam A will first push the pressurization rod A to move. The pressurization rod A compresses the fourth spring. The pressurization rod A allows the air in the first pressurization chamber to enter the second pressurization chamber through the first pressurization port. After that, cam A will push the pressurization rod B to move and compress the air in the second pressurization chamber. At this time, the second control valve is opened and the third control valve is opened. The pressurized air enters the lower side of the deflector through the second pressurization port, the second control valve, the third control valve and the first guide port. When cam A has completed the maximum push stroke, the fourth spring is released, and the fourth spring pushes the pressurization rod A and the pressurization rod B to move in the opposite direction. In this process, The first pressurized chamber and the second pressurized chamber will generate negative pressure air, which is delivered to the positioning block A and the dust removal box through the second pressurized port and the second control valve. The specific delivery process is as follows: when the fourth control valve is opened, the negative pressure enters the dust removal box through the second control valve, the fourth control valve and the first negative pressure port, so that negative pressure is generated inside the dust removal box, and the dust inside the lamp holder enters the dust removal box through one side of the dust removal box, thereby achieving the dust removal effect and ensuring that there is no dust inside the lamp holder; when the fourth control valve is closed and the first control valve is opened, the negative pressure air is delivered to the negative pressure port through the second control valve, the first control valve and the pipeline, and the mast is adsorbed through the negative pressure port, thereby further improving the clamping and positioning effect of the clamping mechanism on the mast.

[0010] The working process of the identification mechanism is as follows: the driving motor drives the transmission disk to rotate, the electromagnet B is energized, and the telescopic rod on the electromagnet B pushes the pawl B to engage with the second ratchet gear. At the same time, the pawl B compresses the first torsion spring, that is, the transmission disk drives the control disk to rotate synchronously, and the control disk drives the rotating wheel, the lever A, and the lever B to rotate synchronously. During the above rotation process, the external wind blows the lever A and the lever B to rotate a certain angle, and the lever A drives the sliding block to slide on the annular shaft, and the sliding block compresses the annular spring. The sensor A detects the compressed force of the annular spring in real time and feeds back the data to the control system. The sensors A on both sides detect the force of the lever A and the lever B compressing the annular spring, and the pressure data is analyzed by the control system. When facing the wind direction, the sensor A is subjected to the greatest pressure. When facing away from the wind direction, the pressure is minimal. Through the above design, real-time detection of wind direction can be achieved, and the angle of the air deflector can be adjusted after analysis by the control system. The specific adjustment process is as follows: when the electromagnet B loses power, the first torsion spring is released, and the first torsion spring pushes the pawl B to disengage from the control disk. At this time, the electromagnet C is energized, and the telescopic rod on the electromagnet C pushes the pawl C to engage with the third ratchet gear. At the same time, the pawl C compresses the first torsion spring, that is, the transmission disk drives the control gear to rotate in the opposite direction, and the control gear drives the lifting gear to rotate synchronously through the control belt. The lifting gear drives the air deflector to rotate to a position facing the wind direction. At this time, the air deflector blocks the wind and guides the lighting lamp, reduces the influence of external wind force on the lighting lamp, and improves the stability and service life of the lighting lamp.

[0019] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0020] 1. The clamping mechanism is convenient for multiple position changes. When one side of cam B or cam C moves to the maximum push stroke, cam B will push the push plate A to move, and the push plate A will push the reciprocating rod A to move on the fixed plate. At the same time, the reciprocating rod A compresses the reset spring, and the reciprocating rod A drives the positioning block A to contact the outer surface of the mast.

The above double positioning treatment ensures the reliability of mast clamping. Through the above design, it is convenient to change the position of the lamp holder multiple times to adapt to different environmental requirements.

[0021] 2. Divert external wind to reduce adverse effects on the lamp holder. The lifting gear drives the deflector to rotate to a position facing the wind direction. At this time, the deflector blocks the wind and diverts the lamp, reducing the impact of external wind on the lamp and improving the stability and service life of the lamp.

[0022] 3. Wind direction detection, real-time adjustment of the diversion angle to achieve the best diversion effect. External wind blows the lever A and lever B to rotate a certain angle, and lever A drives the sliding block to slide on the annular shaft, and the sliding block compresses the annular spring. Sensor A detects the force of the compressed annular spring in real time and feeds the data back to the control system. The force of lever A and lever B compressing the annular spring is detected by sensors A on both sides, and the pressure data is analyzed by the control system. When facing the wind direction, sensor A is subjected to the greatest pressure, and when facing away from the wind direction, it is subjected to the least pressure. The above design can realize real-time detection of wind direction, and adjust the angle of the deflector after analysis by the control system. The above design can adjust the diversion angle in real time, thereby reducing the adverse effects of external wind on the lamp holder and extending the service life of the lamp holder and lighting.

[0042] Press the start button on the control panel 1, the device is powered on, and the staff places the device at the corresponding position of the mast 12. The clamping mechanism starts to work and locks the device on the mast 12. After that, the identification mechanism identifies the wind direction and adjusts the angle of the air guide cover 16 according to the wind direction to reduce the adverse effect of the wind on the lighting lamp 15. The dust removal box 3, the positioning block A26, and the air guide cover 16 are pressurized or negatively pressurized by the pressurizing mechanism.

[0043] The working process of the clamping mechanism is as follows: the driving motor 2 drives the active disk 28 to rotate, and the electromagnet A282 is energized (all the electromagnets described below are push-pull electromagnets, and the telescopic rod is a reciprocating component on the electromagnet), and the telescopic rod on the electromagnet A282 pushes the pawl A281 to engage with the first ratchet gear, that is, the active disk 28 drives the active gear 211 to rotate synchronously, and the active gear 211 drives the driven gear B221 and the driven gear C231 to rotate synchronously through the transmission belt 241, and the driven gear B221 and the driven gear C231 respectively drive the cam B22 and the cam C23 to rotate, and the cam B22 and the cam C23 both drive the pushing mechanism to move. The specific working process of the pushing mechanism As follows: when one side of the cam B22 or the cam C23 moves to the maximum push stroke, the cam B22 will push the push plate A24 to move, and the push plate A24 will push the reciprocating rod A25 to move on the fixed plate 27. At the same time, the reciprocating rod A25 compresses the reset spring 251, and the reciprocating rod A25 drives the positioning block A26 to contact the outer surface of the mast 12. Under the joint action of the cam B22 and the cam C23, the positioning blocks A26 on both sides clamp the mast 12 to form the first repositioning clamping, and adsorb the mast 12 through the negative pressure port 261 on the positioning block A26 (the negative pressure adsorption process is described below) to form the second repositioning clamping. The above double positioning process ensures the reliability of the mast 12 clamping;

[0044] The pressurization working process is as follows: the driving gear 211 drives the cam A21 to rotate. When one side of the cam A21 moves to the maximum push stroke, the cam A21 will first push the pressurization rod A41 to move. The pressurization rod A41 compresses the fourth spring. The pressurization rod A41 allows the air in the first pressurization chamber to enter the second pressurization chamber through the first pressurization port. After that, the cam A21 will push the pressurization rod B42 to move and compress the air in the second pressurization chamber. At this time, the second control valve is opened and the third control valve is opened. The pressurized air enters the lower side of the deflector 16 through the second pressurization port, the second control valve, the third control valve, and the first guide port. When the cam A21 has completed the maximum push stroke, the fourth spring is released, and the fourth spring pushes the pressurization rod A41 and the pressurization rod B42 to move in the opposite direction. During the process, the first pressurized chamber and the second pressurized chamber will generate negative pressure air, and this part of the negative pressure air is transported to the positioning block A26 and the dust removal box 3 through the second pressurized port and the second control valve. The specific transportation process is as follows: when the fourth control valve is opened, the negative pressure enters the dust removal box 3 through the second control valve, the fourth control valve, and the first negative pressure port, so that negative pressure is generated inside the dust removal box 3, and the dust inside the lamp holder 11 enters the dust removal box 3 through one side of the dust removal box 3, thereby achieving the dust removal effect and ensuring that there is no dust inside the lamp holder 11; when the fourth control valve is closed and the first control valve is opened, the negative pressure air is transported to the negative pressure port 261 through the second control valve, the first control valve, and the pipeline, and the mast 12 is adsorbed through the negative pressure port 261, thereby further improving the clamping and positioning effect of the clamping mechanism on the mast 12.

At the same time, the pawl B181 compresses the first torsion spring, that is, the transmission disk 18 drives the control disk 35 to rotate synchronously, and the control disk 35 drives the rotating wheel 34, the lever A32, and the lever B33 to rotate synchronously. During the above rotation process, the external wind blows the lever A32 and the lever B33 to rotate a certain angle, and the lever A32 drives the sliding block 36 to slide on the annular shaft 38, and the sliding block 36 compresses the annular spring 39. The sensor A37 detects the force of the compressed annular spring 39 in real time and feeds back the data to the control system. The sensors A37 on both sides detect the force of the lever A32 and the lever B33 compressing the annular spring 39, and the pressure data is analyzed by the control system. When facing the wind direction, the sensor A37 is affected The pressure is the largest when facing away from the wind direction, and the pressure is the smallest. Through the above design, real-time detection of wind direction can be achieved, and after analysis by the control system, the angle of the air deflector 16 can be adjusted. The specific adjustment process is as follows: the electromagnet B182 loses power, the first torsion spring is released, and the first torsion spring pushes the pawl B181 to disengage from the control disk 35. At this time, the electromagnet C184 is energized, and the telescopic rod on the electromagnet C184 pushes the pawl C183 to engage with the third ratchet gear tooth shape. At the same time, the pawl C183 compresses the first torsion spring, that is, the transmission disk 18 drives the control gear 171 to rotate in the opposite direction, and the control gear 171 drives the lifting gear 162 to rotate synchronously through the control belt 17, and the lifting gear 162 drives the air deflector 16 to rotate to a position facing the wind direction. At this time, the air deflector 16 blocks the wind and guides the lighting lamp 15, reduces the influence of external wind force on the lighting lamp 15, and improves the stability and service life of the lighting lamp 15.

[0053] A control panel 1 is mounted on the lamp holder 11 , and an encoder is built into the driving motor 2 .

[0054] Working principle of the present invention:

[0055] Press the start button on the control panel 1, the device is powered on, and the staff places the device at the corresponding position of the mast 12. The clamping mechanism starts to work and locks the device on the mast 12. After that, the identification mechanism identifies the wind direction and adjusts the angle of the air guide cover 16 according to the wind direction to reduce the adverse effect of the wind on the lighting lamp 15. The dust removal box 3, the positioning block A26, and the air guide cover 16 are pressurized or negatively pressurized by the pressurizing mechanism.

[0056] The working process of the clamping mechanism is as follows: the driving motor 2 drives the active disk 28 to rotate, and the electromagnet A282 is energized (all the electromagnets described below are push-pull electromagnets, and the telescopic rod is a reciprocating component on the electromagnet), and the telescopic rod on the electromagnet A282 pushes the pawl A281 to engage with the first ratchet gear, that is, the active disk 28 drives the active gear 211 to rotate synchronously, and the active gear 211 drives the driven gear B221 and the driven gear C231 to rotate synchronously through the transmission belt 241, and the driven gear B221 and the driven gear C231 respectively drive the cam B22 and the cam C23 to rotate, and the cam B22 and the cam C23 both drive the pushing mechanism to move. The specific working process of the pushing mechanism As follows: when one side of the cam B22 or the cam C23 moves to the maximum push stroke, the cam B22 will push the push plate A24 to move, and the push plate A24 will push the reciprocating rod A25 to move on the fixed plate 27. At the same time, the reciprocating rod A25 compresses the reset spring 251, and the reciprocating rod A25 drives the positioning block A26 to contact the outer surface of the mast 12. Under the joint action of the cam B22 and the cam C23, the positioning blocks A26 on both sides clamp the mast 12 to form the first repositioning clamping, and adsorb the mast 12 through the negative pressure port 261 on the positioning block A26 (the negative pressure adsorption process is described below) to form the second repositioning clamping. The above double positioning process ensures the reliability of the mast 12 clamping;

[0057] The pressurization working process is as follows: the driving gear 211 drives the cam A21 to rotate. When one side of the cam A21 moves to the maximum push stroke, the cam A21 will first push the pressurization rod A41 to move. The pressurization rod A41 compresses the fourth spring. The pressurization rod A41 allows the air in the first pressurization chamber to enter the second pressurization chamber through the first pressurization port. After that, the cam A21 will push the pressurization rod B42 to move and compress the air in the second pressurization chamber. At this time, the second control valve is opened and the third control valve is opened. The pressurized air enters the lower side of the deflector 16 through the second pressurization port, the second control valve, the third control valve, and the first guide port. When the cam A21 has completed the maximum push stroke, the fourth spring is released, and the fourth spring pushes the pressurization rod A41 and the pressurization rod B42 to move in the opposite direction. During the process, the first pressurized chamber and the second pressurized chamber will generate negative pressure air, and this part of the negative pressure air is transported to the positioning block A26 and the dust removal box 3 through the second pressurized port and the second control valve. The specific transportation process is as follows: when the fourth control valve is opened, the negative pressure enters the dust removal box 3 through the second control valve, the fourth control valve, and the first negative pressure port, so that negative pressure is generated inside the dust removal box 3, and the dust inside the lamp holder 11 enters the dust removal box 3 through one side of the dust removal box 3, thereby achieving the dust removal effect and ensuring that there is no dust inside the lamp holder 11; when the fourth control valve is closed and the first control valve is opened, the negative pressure air is transported to the negative pressure port 261 through the second control valve, the first control valve, and the pipeline, and the mast 12 is adsorbed through the negative pressure port 261, thereby further improving the clamping and positioning effect of the clamping mechanism on the mast 12.

[0058] The working process of the identification mechanism is as follows: the driving motor 2 drives the transmission disk 18 to rotate, the electromagnet B182 is energized, and the telescopic rod on the electromagnet B182 pushes the pawl B181 to engage with the second ratchet gear. At the same time, the pawl B181 compresses the first torsion spring, that is, the transmission disk 18 drives the control disk 35 to rotate synchronously, and the control disk 35 drives the rotating wheel 34, the lever A32, and the lever B33 to rotate synchronously. During the above rotation process, the external wind blows the lever A32 and the lever B33 to rotate a certain angle, and the lever A32 drives the sliding block 36 to slide on the annular shaft 38, and the sliding block 36 compresses the annular spring 39. The sensor A37 detects the force of the compressed annular spring 39 in real time and feeds back the data to the control system. The sensors A37 on both sides detect the force of the lever A32 and the lever B33 compressing the annular spring 39, and the pressure data is analyzed by the control system. When facing the wind direction, the sensor A37 is affected The pressure is the largest when facing away from the wind direction, and the pressure is the smallest. Through the above design, real-time detection of wind direction can be achieved, and after analysis by the control system, the angle of the air deflector 16 can be adjusted. The specific adjustment process is as follows: the electromagnet B182 loses power, the first torsion spring is released, and the first torsion spring pushes the pawl B181 to disengage from the control disk 35. At this time, the electromagnet C184 is energized, and the telescopic rod on the electromagnet C184 pushes the pawl C183 to engage with the third ratchet gear tooth shape. At the same time, the pawl C183 compresses the first torsion spring, that is, the transmission disk 18 drives the control gear 171 to rotate in the opposite direction, and the control gear 171 drives the lifting gear 162 to rotate synchronously through the control belt 17, and the lifting gear 162 drives the air deflector 16 to rotate to a position facing the wind direction. At this time, the air deflector 16 blocks the wind and guides the lighting lamp 15, reduces the influence of external wind force on the lighting lamp 15, and improves the stability and service life of the lighting lamp 15.

[0059] The drive motor 2 is internally provided with an encoder, which can detect the angle and position during the above-mentioned rotation process.
