Description

Technical Field

[0001] This utility model relates to a synchronous control device for the sliding construction of photovoltaic brackets, belonging to the field of photovoltaic system bracket technology. Background Technology

[0002] In recent years, with the rapid development of clean energy, photovoltaic power generation systems have been increasingly widely used in agriculture and animal husbandry. In particular, the construction of photovoltaic facilities within farms can achieve green power generation while saving land resources, offering significant economic and environmental benefits. However, installing photovoltaic brackets on existing farm roofs (such as chicken coops) often faces unique limitations, such as low roof structural strength and stringent waterproofing and sealing requirements. Since chicken coop roofs cannot withstand foot traffic during construction, and strict rainproofing and sealing performance must be ensured, the installation of photovoltaic brackets presents considerable difficulties.

[0003] To overcome these challenges, technical personnel have developed a modular installation and cumulative sliding construction method. This method involves first assembling the portal frame and upper photovoltaic modules on the ground, and then gradually moving the assembled modules to the designed position via a sliding mechanism. This avoids people stepping on the roof. However, the sliding construction process involves multiple modules that need to move synchronously. If the modules do not slide synchronously, it can lead to uneven stress on the structure, deviation of the sliding track, or even jamming or collision. This not only affects construction efficiency and quality but may also cause safety risks. Therefore, improvements are urgently needed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model designs a synchronous control device for the sliding construction of photovoltaic brackets, which can monitor the asynchronous sliding of multiple support points at all times, and can safely, efficiently and accurately assist in the implementation of photovoltaic bracket sliding construction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A synchronous control device for the sliding construction of a photovoltaic support includes multiple pairs of parallel sliding adjustment mechanisms. Each sliding adjustment mechanism includes a sliding frame, a sliding rail frame, a pull rope, and a mechanical winch. The sliding rail frame is fixedly installed on the ground, and the sliding frame is slidably installed on its top. The mechanical winch is located at the end of the sliding rail frame and installed on the ground. One end of the pull rope is connected to the output end of the mechanical winch, and the other end of the pull rope is connected to the sliding frame. The device also includes a gear counting sensor, a controller, and an audible and visual alarm. The gear counting sensor is installed on the drive gear of the mechanical winch and is used to emit an electrical signal when the drive gear rotates one revolution. The controller is electrically connected to the gear counting sensor, and the audible and visual alarm is electrically connected to the controller.

[0006] Furthermore, a base plate is fixedly installed at the bottom end of the mechanical winch.

[0007] Furthermore, a clamping and centering mechanism is provided at the bottom end of the base plate. The clamping and centering mechanism includes a support base, and the base plate is disposed at the top of the support base. A clamping assembly for clamping the base plate is installed on the support base. The clamping assembly includes two clamping discs symmetrically disposed on both sides of the support base and an adjusting assembly for adjusting the tightness of the clamping discs. The clamping discs are cylindrical structures with a right-angled trapezoidal cross-section.

[0008] Furthermore, the adjustment assembly includes two mounting plates respectively disposed on both sides of the support base, and a rotating shaft is rotatably connected between the two mounting plates. The rotating shaft rotatably passes through the support base, and both clamping discs are concentrically fixedly sleeved on the rotating shaft. One end of the rotating shaft rotatably passes through the mounting plate and is fixedly connected to a rotating handle.

[0009] Furthermore, the top of the support base has several pairs of bolt holes symmetrically arranged along the vertical axis of rotation, and a positioning pin is installed in one pair of bolt holes.

[0010] Furthermore, the slide rail frame is provided with scale markings at equal intervals along its length.

[0011] Compared with the prior art, this utility model has the following features and beneficial effects: This invention achieves real-time monitoring and comparison of displacement at multiple sliding points by setting up a gear counting sensor and controller. It is low in cost and highly reliable, making it very suitable for use in construction site environments. The audible and visual alarm system provides immediate and conspicuous warnings, ensuring that operators can detect any signs of asynchrony and stop the machine immediately, greatly improving the safety and controllability of the construction process. Furthermore, it has a simple structure, is easy to install and maintain, and does not change the main process of the original sliding construction, making it highly practical.

[0014] The present invention will now be described in more detail with reference to the embodiments.

[0015] like Figures 1 to 5 As shown, the synchronous control device for the sliding construction of the photovoltaic support in this embodiment includes multiple pairs of sliding adjustment mechanisms arranged in parallel, with each pair of sliding adjustment mechanisms located on both sides of the chicken house.

[0016] Specifically, the sliding adjustment mechanism includes a sliding frame 1, a slide rail frame 2, a pull rope 4, and a mechanical winch 5. The slide rail frame 2 is fixedly installed on the ground, the sliding frame 1 is slidably installed on the top of the slide rail frame 2, the mechanical winch 5 is located at the end of the slide rail frame 2 and installed on the ground, one end of the pull rope 4 is connected to the output end of the mechanical winch 5, and the other end of the pull rope 4 is connected to the sliding frame 1.

[0017] Each pair of sliding adjustment mechanisms has a sliding frame 1 that is pulled and moves synchronously by a mechanical winch 5 and a pull rope 4, which makes it easier to install photovoltaic brackets above the chicken house.

[0018] Please see Figure 1 In this embodiment, the sliding frame 1, the sliding rail frame 2, the pull rope 4 and the mechanical winch 5 are all schematic diagrams and do not represent their actual size or shape. The mechanical winch 5 is existing technology, and its principle will not be described in detail.

[0019] In this embodiment, a gear counting sensor 501, a controller 7, and an audible and visual alarm 8 are also included. The gear counting sensor 501 is installed on the drive gear of the mechanical winch 5 and is used to generate an electrical signal when the drive gear rotates one revolution. In this embodiment, the gear counting sensor 501 can generate a pulse electrical signal. The controller 7 is electrically connected to the gear counting sensor 501, and the audible and visual alarm 8 is electrically connected to the controller 7.

[0020] During construction, operators simultaneously activate each mechanical winch 5, using the winding rope 4 to pull the sliding frame 1 and photovoltaic modules forward along the slide rail 2. During this sliding process, each gear counting sensor 501 monitors the number of rotations of the corresponding drive gear in real time and converts the rotation count signal into a displacement signal, which is then sent to the controller 7.

[0021] The controller 7 is used to monitor displacement data. Once it is found that the difference between the displacement of a certain mechanical winch 5 and the displacement of other mechanical winches 5 exceeds a preset allowable threshold (the allowable threshold in this embodiment is 5mm), the controller 7 will immediately send a command to the audible and visual alarm 8.

[0022] Upon receiving the signal, the audible and visual alarm 8 simultaneously activates a buzzer and a red flashing light, providing a clear and urgent warning to the on-site operators. Upon hearing or seeing the alarm, operators can immediately stop operation and manually fine-tune the lagging or leading mechanical winch 5 to align its displacement with the other mechanical winches 5. This allows for early intervention, effectively preventing serious accidents such as track jamming and structural deformation caused by accumulated errors.

[0023] When there are no abnormal conditions, the audible and visual alarm 8 will not emit a sound and will light up a green light.

[0024] Furthermore, a base plate 502 is fixedly installed at the bottom of the mechanical winch 5. The base plate 502 provides a larger contact area and mounting surface, which allows the mechanical winch 5 to be installed more stably on the ground, preventing it from overturning or shifting when under force, and ensuring the stability of the traction process.

[0025] Furthermore, a clamping and centering mechanism 6 is provided at the bottom end of the base plate 502. The clamping and centering mechanism 6 includes a support base 604, with the base plate 502 positioned at the top of the support base 604. A clamping assembly for clamping the base plate 502 is installed on the support base 604. The clamping assembly includes two clamping discs 603 symmetrically arranged on both sides of the support base 604 and an adjusting assembly for adjusting the tightness of the clamping discs 603. The clamping discs 603 are cylindrical structures with a right-angled trapezoidal cross-section. The clamping and centering mechanism 6 can position and clamp the mechanical winch 5, ensuring the effective transmission of traction force.

[0026] Specifically, the adjustment assembly includes two mounting plates 602 respectively disposed on both sides of the support base 604. A rotating shaft 607 is rotatably connected between the two mounting plates 602. The rotating shaft 607 is rotatably disposed through the support base 604, and two clamping discs 603 are concentrically fixedly sleeved on the rotating shaft 607. One end of the rotating shaft 607 is rotatably disposed through the mounting plate 602 and fixedly connected to a rotating handle 606. By rotating the rotating handle 606, the rotating shaft 607 can be rotated, thereby adjusting the position of the clamping discs 603. When the thicker side of the clamping disc 603 is close to the base plate 502, the base plate 502 can be clamped.

[0027] In this embodiment, the bottom ends of both sides of the support base 604 are vertically fixedly connected to the fixing base 601, and the mounting plate 602 is vertically fixedly installed on the fixing base 601.

[0028] To ensure effective clamping of the clamping disc 603, the two clamping discs 603 are arranged symmetrically.

[0029] Furthermore, the top of the support base 604 has several pairs of bolt holes symmetrically arranged along the vertical axis 607. One pair of bolt holes is fitted with a positioning post 605. Each pair of bolt holes is symmetrically arranged. Depending on the size of the base plate 501, a suitable pair of bolt holes can be selected. The positioning post 605 is then installed in the bolt holes to limit the position of the base plate 501. The clamping plate 603 is then used to clamp the base plate 501. Since the two clamping plates 603 are symmetrically arranged, they can limit the position of the base plate 501 at the same time, thus playing a centering role. Under the premise that the fixed base 601 ensures the correct installation position, it can effectively ensure that the mechanical winch 5 at the top of the base plate 501 can pull the rope 4 along the slide rail frame 2 to prevent deviation.

[0030] Furthermore, the slide rail 2 is provided with equally spaced scale markings 3 along its length, providing operators with an intuitive visual reference. During the sliding process, in addition to monitoring with electronic sensors, operators can also directly observe the scale positions of each slide rail 1 on the slide rail 2 for auxiliary manual comparison, thus doubly verifying the synchronization of the sliding and improving the redundancy, safety, and reliability of the system.

[0031] The working principle of this utility model is as follows: During construction, the operator simultaneously starts each mechanical winch 5, and pulls the upper sliding frame 1 and photovoltaic module forward along the slide rail frame 2 by winding the pull rope 4. During the sliding process, each gear counting sensor 501 monitors the number of rotations of the corresponding drive gear in real time, and converts the rotation count signal into a displacement signal and sends it to the controller 7.

[0032] The controller 7 is used to monitor displacement data. Once it is found that the difference between the displacement of a certain mechanical winch 5 and the displacement of other mechanical winches 5 exceeds a preset allowable threshold (the allowable threshold in this embodiment is 5mm), the controller 7 will immediately send a command to the audible and visual alarm 8.

[0033] Upon receiving the signal, the audible and visual alarm 8 simultaneously activates a buzzer and a red flashing light, providing a clear and urgent warning to the on-site operators. Upon hearing or seeing the alarm, operators can immediately stop operation and manually fine-tune the lagging or leading mechanical winch 5 to align its displacement with the other mechanical winches 5. This allows for early intervention, effectively preventing serious accidents such as track jamming and structural deformation caused by accumulated errors.
