Description

Technical Field

[0001] This application relates to the field of photovoltaic bracket manufacturing technology, specifically a speed control device for a photovoltaic bracket production line. Background Technology

[0002] Photovoltaic brackets are structural devices used to support and fix solar panels in a solar photovoltaic power generation system. They are mainly made of materials such as steel and aluminum alloys and have the characteristics of stable support, wind and earthquake resistance, and corrosion resistance. Their core function is to fix the solar panels at the optimal angle and orientation to maximize the reception of solar radiation, while protecting the solar panels from the influence of the external environment. The photovoltaic bracket production line mainly covers machining, heat treatment, assembly and other parts. It is usually composed of uncoilers, punching devices, forming machines, cutting devices, unloading devices and other components to produce photovoltaic brackets of the required size for solar photovoltaic power generation systems.

[0003] However, in existing photovoltaic bracket production lines, it has been found that due to the different processing and transmission speeds between each piece of equipment, speed control devices are usually installed between two pieces of equipment to prevent the transmission speed of the steel plate by the front equipment from being too fast. However, due to the production line environment, dust accumulates on the infrared emitter of the infrared sensor, which directly affects the detection accuracy of the infrared sensor, resulting in inaccurate speed control. Summary of the Invention

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this application provides a speed control device for a photovoltaic bracket production line. This device controls the transmission speed of the steel plate by detecting the distance to the steel plate using an infrared sensor, while simultaneously blowing away dust from the surface of the infrared emitter of the infrared sensor using an exhaust airflow, thus preventing dust from affecting the detection accuracy. This solves the problem that dust accumulates on the infrared emitter of the infrared sensor due to the production line environment, affecting the detection accuracy of the infrared sensor and consequently the speed control precision.

[0006] To achieve the above objectives, this application provides the following technical solution: a speed control device for a photovoltaic support production line, comprising a ground, a base plate fixedly installed on the inner bottom wall of the ground, an infrared sensor fixedly installed on the upper surface of the base plate, an air pump fixedly installed on the upper surface of the ground, a hose fixedly connected to the output end of the air pump, a nozzle fixedly installed at the other end of the hose, a guide frame fixedly connected to the upper surface of the base plate, a sliding block slidably connected to the inner wall of the guide frame, an installation rod fixedly connected to the left side of the sliding block, the left end of the installation rod fixedly connected to the right side of the nozzle, the outer surface of the installation rod slidably connected to the inner wall of the guide frame, and a telescopic rod fixedly installed on the upper surface of the base plate, the output end of the telescopic rod fixedly connected to the inner wall of the sliding block.

[0007] The above scheme controls the transfer speed of the steel plate to prevent excessive sagging. Simultaneously, it improves detection accuracy by cleaning the infrared emitter of the infrared sensor. The infrared sensor is installed on the upper surface of the base plate. It emits infrared light to detect the distance to the steel plate. When the steel plate sagging excessively, the distance between the steel plate and the infrared sensor decreases. At this point, the front of the conveyor stops transporting the steel plate, while the rear continues to pull it. The sagging position of the steel plate slowly rises until the distance between the steel plate and the infrared sensor reaches the standard, allowing the front to continue transporting the steel plate. This achieves speed control and prevents excessive sagging. A telescopic rod is used to move the nozzle via a sliding block and mounting rod. An air pump, hose, and nozzle allow airflow to be sprayed onto the infrared emitter of the infrared sensor, blowing away dust from its surface and cleaning the sensor to prevent dust from affecting detection accuracy.

[0008] Furthermore, a connecting frame is fixedly installed on the upper surface of the base plate, and two square rods are fixedly installed on the upper surface of the connecting frame.

[0009] The above method involves installing the connecting frame on the upper surface of the base plate and fixing it with bolts to achieve the installation of the connecting frame, and then installing the square rod on the upper surface of the connecting frame to achieve the installation of the square rod.

[0010] Furthermore, a steel plate body is provided above the ground, and columns arranged at equal intervals are fixedly installed on the upper surface of the ground.

[0011] The above scheme involves placing the steel plate body above the ground, with a long groove on the ground surface. When the steel plate body is transferred, it can hang down in the middle position, allowing the column to be installed on the upper surface of the ground. The column is then fixed with bolt assemblies, allowing it to be installed at the edge of the groove.

[0012] Furthermore, there are connecting rods arranged at equal intervals above the ground, and both ends of each connecting rod are fixedly connected to the outer surface of the corresponding column.

[0013] The above method involves placing the connecting rod above the ground, connecting one end of the connecting rod to the corresponding column, and connecting the other end of the connecting rod to the corresponding column on the other side, thereby fixing the connecting rod.

[0014] Furthermore, there are horizontal bars arranged at equal intervals above the ground, and both ends of each horizontal bar are fixedly connected to the outer surface of the corresponding column.

[0015] The above solution involves placing a horizontal bar above the ground, connecting one end of the horizontal bar to the corresponding upright, and connecting the other end of the horizontal bar to the corresponding upright, so that the upright, connecting rod, and horizontal bar can form a protective frame to prevent operators from stepping into the ditch and to warn operators.

[0016] Furthermore, the top of each square rod is fixedly connected to the bottom surface of the corresponding connecting rod, and a reset switch is fixedly installed on the bottom surface of one of the connecting rods.

[0017] The above method connects the top of the square rod to the bottom of the corresponding connecting rod, allowing the square rod, connecting rod, and connecting frame to be connected. The reset switch is then installed on the bottom of the connecting rod, thus achieving the installation of the reset switch.

[0018] Furthermore, the opening and closing end of the reset switch is connected to a suspension rope, and the bottom end of the suspension rope is connected to a counterweight.

[0019] The above scheme involves installing a hoisting rope at the opening and closing end of a reset switch and connecting it by knotting. The counterweight is then connected to the bottom end of the hoisting rope. By pulling the reset switch using the counterweight and hoisting rope, when the infrared sensor below fails, the steel plate continues to rise, causing its surface to contact the counterweight. At this point, the counterweight rises, releasing the pull on the reset switch, which then automatically resets. This stops the processing of the steel plate by the downstream device, while the upstream device transfers the steel plate until its drooping position moves away from the counterweight, causing the reset switch to be pulled.

[0020] Furthermore, the suspension rope is made of polyamide fiber.

[0021] The above solution uses polyamide fiber material for the suspension rope, which has high strength, wear resistance, and flexibility, and can be used for a long time to continuously suspend the counterweight.

[0022] Beneficial effects

[0023] This type of speed control equipment for photovoltaic bracket production line uses components such as infrared sensors, nozzles, and telescopic rods. The infrared sensors detect the distance to the steel plate. When the steel plate sags excessively, the front conveyor stops transporting the plate, while the rear conveyor continues to pull the plate, causing it to slowly rise until the distance between the steel plate and the infrared sensor reaches the target. Then, the front conveyor resumes transporting the plate, achieving speed control and preventing excessive sag. The telescopic rod moves the nozzle via a sliding block and mounting rod, spraying air onto the infrared emitter of the infrared sensor through an air pump, hose, and nozzle to blow away surface dust and prevent it from affecting detection accuracy. A counterweight and suspension rope are used. When the infrared sensor fails, the steel plate continues to rise until it lifts the counterweight. At this point, the suspension rope and counterweight release the tension on the reset switch, causing it to automatically reset. This stops the rear conveyor from processing the steel plate, while the front conveyor continues transporting the plate until its sag moves away from the counterweight, causing the reset switch to be pulled again, preventing the steel plate from being continuously pulled after the infrared sensor fails.

[0034] Please see Figure 1 , Figure 2 and Figure 3 A steel plate body 13 is provided above the ground 1. Columns 14 arranged at equal intervals are fixedly installed on the upper surface of the ground 1. The steel plate body 13 is placed above the ground 1. Long grooves are opened on the surface of the ground 1. When the steel plate body 13 is transferred, the steel plate body 13 can hang down in the middle position to install the columns 14 on the upper surface of the ground 1. The columns 14 are fixed by bolt assemblies so that the columns 14 can be installed at the edge of the groove.

[0035] Please see Figure 1 and Figure 3 Above the ground 1, there are connecting rods 15 arranged at equal intervals. Both ends of each connecting rod 15 are fixedly connected to the outer surface of the corresponding column 14. The connecting rods 15 are set above the ground 1, and one end of the connecting rod 15 is connected to the corresponding column 14, and the other end of the connecting rod 15 is connected to the corresponding column 14 on the other side, so as to fix the connecting rod 15.

[0036] Please see Figure 1 , Figure 2 and Figure 3Above the ground 1, there are horizontal bars 16 arranged at equal intervals. Both ends of each horizontal bar 16 are fixedly connected to the outer surface of the corresponding column 14. The horizontal bars 16 are set above the ground 1, one end of the horizontal bar 16 is connected to the corresponding column 14, and the other end of the horizontal bar 16 is connected to the corresponding column 14, so that the column 14, connecting rod 15 and horizontal bar 16 can form a protective frame to prevent operators from stepping into the ditch and to warn operators.

[0037] Please see Figure 3 and Figure 4 The top of each square rod 12 is fixedly connected to the bottom surface of the corresponding connecting rod 15. A reset switch 17 is fixedly installed on the bottom surface of one of the connecting rods 15. The top of the square rod 12 is connected to the bottom surface of the corresponding connecting rod 15 so that the square rod 12, the connecting rod 15 and the connecting frame 11 can be connected. The reset switch 17 is installed on the bottom surface of the connecting rod 15 to realize the installation of the reset switch 17.

[0038] Please see Figure 3 The opening and closing ends of the reset switch 17 are connected to a lifting rope 18, and the bottom end of the lifting rope 18 is connected to a counterweight 19. The lifting rope 18 is installed on the opening and closing ends of the reset switch 17 and connected by knotting. The counterweight 19 is connected to the bottom end of the lifting rope 18 to achieve the connection of the counterweight 19. The reset switch 17 is pulled by the counterweight 19 and the lifting rope 18. When the infrared sensor 3 below fails, the downward position of the steel plate continues to rise, so that the surface of the steel plate contacts the counterweight 19. At this time, the counterweight 19 rises, releasing the pull on the reset switch 17. The reset switch 17 automatically resets, which can stop the processing of the steel plate by the rear device. The front device will transfer the steel plate until the downward position of the steel plate is far away from the counterweight 19, so that the reset switch 17 is pulled.

[0039] Please see Figure 3 The suspension rope 18 is made of polyamide fiber. The suspension rope 18 is made of polyamide fiber, which has the characteristics of high strength, wear resistance and flexibility, and can be used for a long time to continuously suspend the counterweight 19.

[0040] This embodiment describes a speed control device for a photovoltaic support production line. It incorporates components such as an infrared sensor 3, a nozzle 6, and a telescopic rod 10. The infrared sensor 3 detects the distance between the steel plate and the sensor. When the steel plate sags excessively, the front conveyor stops transporting the plate, while the rear conveyor continues to pull the plate, slowly raising its sag position until the distance between the steel plate and the infrared sensor 3 reaches the target. Then, the front conveyor resumes transporting the plate, thus controlling the speed and preventing excessive sag. The telescopic rod 10 causes the sliding block 8 and the mounting rod 9 to move the nozzle 6. Airflow is then sprayed onto the infrared sensor 6 via an air pump 4, a hose 5, and the nozzle 6. The infrared emitter of sensor 3 blows away surface dust to prevent dust from affecting detection accuracy. A counterweight 19 and a suspension rope 18 are set up. When the infrared sensor 3 fails, the steel plate continues to rise until it lifts the counterweight 19. At this time, the suspension rope 18 and the counterweight 19 release the pull on the reset switch 17, so that the reset switch 17 automatically resets. This allows the rear device to stop processing the steel plate, and the front device to transfer the steel plate until the steel plate's drooping position is far away from the counterweight 19, so that the reset switch 17 is pulled again, preventing the steel plate from being continuously pulled after the infrared sensor 3 fails.

[0041] It should be noted that the telescopic rod 10 is electrically driven, which enables the sliding block 8 to move quickly and stably. The connecting frame 11 includes four connecting square tubes, which are connected by bolts. When the reset switch 17 is pulled by the counterweight 19, the device is not affected. When the counterweight 19 is raised and the hoisting rope 18 is retracted, the reset switch 17 is automatically reset, which can automatically stop the equipment behind and stop pulling on the steel plate.

[0042] The working principle of the above embodiments is as follows:

[0043] By installing an infrared sensor 3 on the upper surface of the base plate 2, the distance to the drooping position of the steel plate body 13 can be detected. When the steel plate droops excessively, the equipment in front stops, and the steel plate is no longer conveyed. The equipment behind continues to pull the steel plate, causing the drooping position of the steel plate to rise slowly until the distance between the steel plate and the infrared sensor 3 reaches the target. Then, the equipment in front continues to convey the steel plate, achieving speed control and preventing the steel plate from drooping excessively. The telescopic rod 10 causes the sliding block 8 and the mounting rod 9 to move the nozzle 6. The air pump 4, hose 5, and nozzle 6 spray air onto the infrared emitting end of the infrared sensor 3, blowing away surface dust and preventing dust from affecting the detection accuracy. When the infrared sensor... When device 3 fails, the steel plate continues to rise until it lifts the counterweight 19. At this point, the hoisting rope 18 and the counterweight 19 release the tension on the reset switch 17, causing the reset switch 17 to automatically reset. This allows the downstream device to stop processing the steel plate, while the upstream device continues to transport the steel plate until its downward position moves away from the counterweight 19, causing the reset switch 17 to be pulled again. This prevents the steel plate from being continuously pulled after the infrared sensor 3 fails, thus providing a protective effect. By setting up the column 14, connecting rod 15, and crossbar 16, a protective frame can be formed to prevent operators from stepping into the trench and to warn operators.
