Description

Technical Field

[0001] This invention relates to an automatic fault alarm device and method, and more particularly to an automatic fault alarm device and method for solar photovoltaic panels. Background Technology

[0002] Existing photovoltaic panels are generally equipped with angle adjustment structures to ensure that the photovoltaic panels receive sufficient sunlight. However, long-term use will cause wear and tear and aging of the equipment, resulting in excessively large angle adjustment of the photovoltaic panels, making it impossible for them to automatically restore the angle and affecting the power generation efficiency of the photovoltaic panels.

[0003] Existing technology CN211791400U discloses a grid-connected power generation device for single-phase solar photovoltaic power generation, including a drive box. An equipment box, rectangular in shape, is fixedly mounted on the top of the drive box, with its bottom wall size matching the top wall size of the drive box. In this grid-connected power generation device for single-phase solar photovoltaic power generation, when the photovoltaic panel angle adjustment results in significant over-adjustment, a limiting plate will cause the main limiting rod to move backward. This causes the power transmission base block on the main limiting rod to disengage from the gap between the reserve power connection post and the power connection post of the telescopic adjustment control device. This results in the telescopic adjustment control device losing power, forcing the telescopic rod to stop moving. Simultaneously, the rear end of the main limiting rod will trigger the alarm switch of the alarm device, issuing an alarm command and promptly notifying relevant personnel for repairs.

[0004] The aforementioned device triggers an alarm when the photovoltaic panel's tilt angle is too large. However, it fails to issue an alarm when the photovoltaic panel stops rotating at any other angle, thus affecting the photovoltaic panel's power generation efficiency. Summary of the Invention

[0005] Purpose of the invention: The technical problem to be solved by the present invention is to provide an automatic alarm device and method for solar photovoltaic panel faults, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the present invention discloses an automatic alarm device and method for solar photovoltaic panel faults, wherein the device includes: a base, a rotating bracket fixed on the base, a base plate rotatably mounted on the base via the rotating bracket, the base plate being used to install the photovoltaic panel, and a solar sensor being provided on the base;

[0009] Furthermore, the driving component includes:

[0010] A drive motor mounted on the base drives a threaded rod horizontally mounted on the base to rotate. The threaded rod is threadedly connected to the lifting component. A limit plate is fixed on the base. The threaded rod and the limit plate cooperate to drive the lifting component to move up and down. The top of the lifting component is connected to the base plate through a detection component. The lifting component drives the photovoltaic panel on the base plate to rotate as it moves up and down.

[0011] The solar sensor is electrically connected to the drive motor to control the motor's rotation.

[0012] Furthermore, the lifting component includes a movable seat that is threadedly connected to the threaded rod, and the rotation of the threaded rod drives the movable seat to move horizontally;

[0014] The limiting plate is located on the side of the lifting seat and is equipped with a sliding groove;

[0016] Furthermore, the detection component includes a housing fixed to the top of the lifting component, the lower end of the bracket sliding with the housing (106) in the vertical direction and connected by an elastic component, and the upper end sliding with the base plate along its planar direction.

[0017] It also includes a pressure sensor positioned between the bracket and the housing to detect the pressure on the elastic component.

[0018] Furthermore, the elastic component includes a spring disposed inside the outer shell, the outer shell being a hollow structure, the two ends of the spring being fixedly connected to the top and bottom of the outer shell respectively, and an abutment plate being sleeved on the outer side of the middle part of the spring, the outer side of the abutment plate being fixedly connected to the bracket.

[0019] The pressure sensor is located inside the housing and is in contact with the spring to detect the pressure of the spring.

[0020] Furthermore, the detection component also includes an alarm component electrically connected to the pressure sensor, used to trigger an alarm based on the pressure value measured by the pressure sensor.

[0021] Furthermore, the alarm components include an alarm light, a buzzer, and a signal generator, all of which are electrically connected to the pressure sensor. When the pressure signal measured by the pressure sensor exceeds a threshold, the alarm light turns on and off in a preset manner, the buzzer sounds in a preset manner, and the signal generator sends out an alarm signal in a preset manner.

[0022] Furthermore, the movable seat includes: a threaded sleeve fitted on the threaded rod, a movable plate fixed in the horizontal direction on the threaded sleeve, a guide rod fixed vertically on the movable plate, and a lifting seat slidably connected to the guide rod.

[0023] Furthermore, the sliding groove is an upward-opening arc shape.

[0024] In addition, an automatic alarm method for solar photovoltaic panel faults is proposed, which uses the aforementioned automatic alarm device for solar photovoltaic panel faults and includes the following steps:

The buzzer 116 is fixedly connected to the base 101 and electrically connected to the pressure sensor 108, and is located on the side of the base 101 near the alarm light 115. The signal generator 117 is fixedly connected to the base 101 and electrically connected to the pressure sensor 108, and is located on one side of the base 101.

[0044] The driving component 112 includes a threaded rod 201, a threaded sleeve 202, a drive motor 203, and a lifting component 204. The threaded rod 201 is rotatably connected to the base 101 and is located inside the base 101. The threaded sleeve 202 is threadedly connected to the threaded rod 201 and is sleeved on the threaded rod 201. The drive motor 203 is connected to the base 101 and is located on one side of the base 101. The output end of the drive motor 203 is connected to the threaded rod 201.

[0045] The lifting component 204 includes a movable seat 205, a lifting seat 206, a limiting plate 207, and a connecting rod 208. The movable seat 205 includes a movable plate 211, a guide rod 212, and a threaded sleeve 202. The movable plate 211 is fixedly connected to the threaded sleeve 202 and is located on one side of the threaded sleeve 202. The lifting seat 206 is slidably connected to the movable seat 205.

[0048] The automatic alarm device for solar photovoltaic panel faults of the present invention, when the base plate cannot rotate or the rotation resistance increases, the resistance of the bracket driving the base plate to rotate will increase, thereby causing the bracket to drive the abutment plate to move, causing the abutment plate to compress the spring above or below it. When the abutment plate abuts against the pressure sensor, the alarm component will issue an alarm, thereby achieving the purpose of timely detection and alarm issuance when the photovoltaic panel stops rotating at any angle.

[0049] Example:

[0050] First embodiment:

[0051] Please see Figures 1 to 3 ,in Figure 1 This is a schematic diagram of the overall structure of the automatic alarm device for solar photovoltaic panel faults. Figure 2 This is a structural diagram of the alarm components. Figure 3 This is a schematic diagram of the installation structure of the pressure sensor.

[0052] This invention provides an automatic alarm device for solar photovoltaic panel faults, comprising a base 101, a base plate 102, a photovoltaic panel 103, a solar sensor 104, and a driving component 112. The driving component 112 includes a detection assembly 105, which includes a housing 106, a contact plate 107, a spring 108, a pressure sensor 109, a bracket 110, and an alarm component 111. The bracket 110 includes a frame 113 and a rotating shaft 114. The alarm component 111 includes an alarm light 115, a buzzer 116, and a signal generator 117. The driving component 112 drives the housing 106 to perform an arc-shaped movement, thereby causing the housing 106 to move the contact plate 107 and the bracket 110, which in turn drives the base plate. The base plate 102 and the photovoltaic panel 103 rotate to adjust the angle of the photovoltaic panel 103. When the base plate 102 cannot rotate or the rotation resistance increases, the resistance when the bracket 110 drives the base plate 102 to rotate increases. At this time, the movement of the bracket 110 causes the abutment plate 107 to move up or down, so that the abutment plate 107 abuts against the pressure sensor 109 above or below, thereby causing the alarm component 111 to sound an alarm. It can be understood that the above solution can be used to adjust the angle of the photovoltaic panel 103, and can also be used to solve the problem that an existing grid-connected power generation device for single-phase solar photovoltaic power generation can only sound an alarm when the tilt angle of the photovoltaic panel 103 is too large, which affects the power generation efficiency of the photovoltaic panel 103.

[0053] In this specific embodiment, the solar sensor 104 is mounted on the base 101, the base plate 102 is rotatably mounted on the base 101, and the photovoltaic panel 103 is mounted on the base plate 102. The photovoltaic panel 103 is mounted on the base 101 via the base plate 102. The solar sensor 104 detects the position of the sun, and the detection component 105 drives the base plate 102 to rotate, thereby adjusting the angle of the photovoltaic panel 103 so that the photovoltaic panel 103 faces the sun, thus improving power generation efficiency.

[0054] The drive component 112 is mounted on the base 101. The housing 106 is connected to the base 101 via the drive component 112. The abutment plate 107 is slidably connected to the housing 106 and located inside the housing 106. One end of the spring 108 abuts against the abutment plate 107, and the other end of the spring 108 abuts against the housing 106. The spring 108 is located inside the housing 106. The pressure sensor 109 is fixedly connected to the housing 106 and located inside the housing 106. The bracket 110 is fixedly connected to the abutment plate 107 and slidably connected to the base plate 102, and is mounted on the abutment plate 107. The alarm component 111 is mounted on the base 101. The base 101 is electrically connected to the pressure sensor 109. Two limiting plates 207 are provided, and two springs 108 and two pressure sensors 109 are respectively provided on the upper and lower sides of the abutment plate 107. The bottom of the base plate 102 has a moving groove, allowing the bracket 110 to move within the groove. The driving member 112 drives the outer shell 106 to perform an arc-shaped movement, which in turn causes the outer shell 106 to drive the abutment plate 107 and the bracket 110 to perform an arc-shaped movement. When the bracket 110 is at the leftmost end, the base plate 102 tilts to the right; when the bracket 110 is at the rightmost end, the base plate 102 tilts to the left, thereby causing the base plate 102 to drive the photovoltaic... The plate 103 faces different angles. The springs 108 on both sides of the abutment plate 107 are elastic. The abutment plate 107 is positioned in the middle inside the outer shell 106 by the action of the two springs 108. When wear and aging occur between the bottom plate 102 and the base 101, causing the bottom plate 102 to be unable to rotate, the driving component 112 drives the outer shell 106, the abutment plate 107, and the bracket 110 to move. Since the bottom plate 102 cannot rotate, the bracket 110 will move up and down along the moving groove at the bottom of the bottom plate 102, thereby driving the abutment plate 107 to move up and down inside the outer shell 106. When the abutment plate 107 moves up or down and abuts against the inner... After the pressure sensor 109 is engaged, the pressure sensor 109 outputs a signal to the alarm component 111, which then issues an alarm to alert the staff of a malfunction. In the automatic alarm device for solar photovoltaic panel malfunctions of the present invention, when the base plate 102 cannot rotate or the rotational resistance increases, the resistance of the support 110 driving the base plate 102 to rotate increases, causing the support 110 to move the abutment plate 107. This causes the abutment plate 107 to compress the spring 108 above or below it. When the abutment plate 107 abuts against the pressure sensor 109, the alarm component 111 issues an alarm, thus enabling the photovoltaic panel 103 to stop rotating at any angle.The detection component 105 is capable of timely detection and issuing an alarm.

[0055] Secondly, the frame 113 is fixedly connected to the abutment plate 107 and is disposed on the abutment plate 107; the rotating shaft 114 is rotatably connected to the frame 113 and connected to the base plate 102 and is disposed on the base plate 102. There are two rotating shafts 114, which are respectively located on the left and right sides of the frame 113. By rotating the rotating shaft 114, the friction between the rotating shaft 114 and the base plate 102 is reduced, thereby improving the smoothness of the movement of the bracket 110 when driving the base plate 102.

[0056] Meanwhile, the alarm light 115 is fixedly connected to the base 101 and electrically connected to the pressure sensor 109, and is located on one side of the base 101; the buzzer 116 is fixedly connected to the base 101 and electrically connected to the pressure sensor 109, and is located on the side of the base 101 near the alarm light 115; the signal generator 117 is fixedly connected to the base 101 and electrically connected to the pressure sensor 109, and is located on one side of the base 101. When the abutment plate 107 abuts against the pressure sensor 109 above or below, the pressure sensor 109 generates a reading, and then outputs a signal to the alarm light, the buzzer 116 and the signal generator 117. At this time, the alarm light and the buzzer 116 are activated to sound an alarm, and the signal generator 117 sends an alarm to the backend to prevent staff from not being on-site and failing to detect the alarm in time.

[0057] When using the automatic alarm device for solar photovoltaic panel faults in this embodiment, the driving component 112 drives the outer casing 106 to move in an arc shape, thereby causing the abutment plate 107 and the support 110 to move. The support 110 drives the base plate 102 to rotate. When the base plate 102 cannot rotate, the support 110 moves along the moving groove at the bottom of the base plate 102, thereby causing the abutment plate 107 to move along the moving groove at the bottom of the base plate 102. The outer casing 106 continues to move along the arc. Since the rising or falling rate of the support 110 and the abutment plate 107 is faster than the rising or falling rate of the outer casing 106, the abutment plate 107 moves relative to the outer casing 106, thereby causing the abutment plate 107 to abut against the pressure sensor 109 above or below, thus causing the alarm component 111 to issue an alarm, achieving the purpose of timely alarming of faults and avoiding affecting the power generation efficiency of the photovoltaic panel 103.

[0058] Second embodiment:

[0059] Based on the first embodiment, please refer to Figures 4 to 6 , Figure 4 This is a structural schematic diagram of the lifting component in the second embodiment. Figure 5 This is a schematic diagram of the installation structure of the threaded rod in the second embodiment. Figure 6 This is a schematic diagram of the installation structure of the guide rod in the second embodiment. The driving component 112 in this embodiment includes a threaded rod 201, a threaded sleeve 202, a drive motor 203, and a lifting component 204. The lifting component 204 includes a movable seat 205, a lifting seat 206, a limiting plate 207, and a connecting rod 208. The movable seat 205 includes a movable plate 211 and a guide rod 212. The limiting plate 207 has a sliding groove 213.

[0060] In this specific embodiment, the threaded rod 201 is rotatably connected to the base 101 and is located inside the base 101; the threaded sleeve 202 is threadedly connected to the threaded rod 201 and is sleeved on the threaded rod 201; the drive motor 203 is connected to the base 101 and is located on one side of the base 101, and the output end of the drive motor 203 is connected to the threaded rod 201.

[0061] The movable seat 205 is fixedly connected to the threaded sleeve 202 and is located on one side of the threaded sleeve 202; the lifting seat 206 is slidably connected to the movable seat 205 and is disposed on the movable seat 205; the two ends of the connecting rod 208 are fixedly connected to the lifting seat 206 and the outer shell 106 respectively, and the connecting rod 208 is located on the side of the lifting seat 206 near the outer shell 106; the limiting plate 207 is fixedly connected to the base 101 and connected to the lifting seat 206, and is located on one side of the base 101.

[0062] Secondly, the sliding groove 213 is disposed on the limiting plate 207, passes through the limiting plate 207, and cooperates with the sliding shaft 210.

[0063] The drive motor 203 is electrically connected to the solar sensor 104 and the pressure sensor 109, respectively. The solar sensor 104 detects the sun's position and controls the drive motor 203 to rotate. When the pressure sensor 109 is abutted by the abutment plate 107, the drive motor 203 stops rotating, and the lifting seat 206 can slide inside the sliding groove 213 on the limiting plate 207. The sliding groove 213 is arc-shaped. There are two limiting plates 207, located on the lifting seat 206 respectively. On both sides, the operation of the drive motor 203 drives the threaded rod 201 to rotate, which in turn drives the threaded sleeve 202 to move. The threaded sleeve 202 drives the moving seat 205, the lifting seat 206, and the connecting rod 208 to move, which in turn drives the outer shell 106 to move. At the same time, the lifting seat 206 is raised and lowered under the action of the sliding groove 213, thereby achieving the purpose of driving the outer shell 106, the abutment plate 107, and the bracket 110 to perform arc-shaped movements.

[0064] Meanwhile, the seat 209 is slidably connected to the movable seat 205 and is disposed on the movable seat 205; the sliding shaft 210 is rotatably connected to the seat 209 and connected to the limiting plate 207, and is located on one side of the seat 209. There are two sliding shafts 210, which are respectively located on the left and right sides of the seat 209. By rotating the sliding shaft 210 and the seat 209, the friction between the sliding shaft 210 and the limiting plate 207 is reduced.

[0065] In addition, the seat 209 is slidably connected to the movable seat 205 and is disposed on the movable seat 205; the sliding shaft 210 is rotatably connected to the seat 209 and connected to the limiting plate 207, and is located on one side of the seat 209; two guide rods 212 are provided and are respectively located on both sides of the seat 209. The guide rods 212 guide the lifting and lowering of the seat 209, so that the seat 209 can only be lifted and lowered along the direction of the guide rods 212, thereby improving the stability of the seat 209 when it moves.

[0066] Third embodiment:

[0067] An automatic alarm method for solar photovoltaic panel faults, such as Figure 7 As shown, it includes the following steps:

[0068] S101: The solar sensor 104 controls the movement of the drive component 112, so that the drive component 112 drives the outer shell 106, the abutment plate 107 and the bracket 110 to move.

[0069] S102: The support 110 drives the base plate 102 to rotate, so that the base plate 102 drives the photovoltaic panel 103 to face the sun;

[0070] S103: When the base plate 102 can no longer rotate, the bracket 110 and the outer shell 106 move relative to each other;

[0071] S104: The bracket 110 drives the abutment plate 107 to move inside the housing 106, and the abutment plate 107 abuts against the pressure sensor 109;

[0072] S105: After the pressure sensor 109 detects the pressure, it sends a signal to the alarm component 111, causing the alarm component 111 to sound an alarm.

[0073] When the base plate 102 becomes unable to rotate, the movement of the bracket 110 cannot drive the base plate 102 to rotate. Consequently, the bracket 110 can only move along the moving groove at the bottom of the base plate 102. At this time, the outer shell 106 is still moving in an arc under the action of the driving member 112. As a result, the lifting rate of the bracket 110 and the abutment plate 107 is greater than the lifting rate of the outer shell 106. This causes the abutment plate 107 to move inside the outer shell 106. When the abutment plate 107 comes into contact with the pressure sensor 109, the alarm member 111 sounds an alarm, thereby achieving timely fault detection and improving the power generation efficiency of the photovoltaic panel 103.

[0074] This invention provides a concept and method for an automatic alarm device for solar photovoltaic panel faults. Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of the invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technologies.
