Description

Technical Field

[0001] The present invention belongs to the technical field of building structures, and in particular relates to a bracket and an installation method for photovoltaic installation outside an existing building. Background Art

[0002] my country boasts a vast stock of existing multi-story buildings. Most of these buildings date back to different historical periods, with diverse design styles and structural features, but they all face the need for green retrofitting and energy efficiency improvements. Utilizing photovoltaic technology for grid-connected power generation has become a key approach to greening existing buildings. Existing high-rise buildings typically install photovoltaics on the rooftops of multi-story buildings for grid-connected power generation. In actual installations, some relatively square and regular multi-story buildings have smaller rooftops, so the amount of power generated by rooftop photovoltaics is relatively limited. While these buildings have large areas on their exterior facades where photovoltaics can be applied, the current development of photovoltaic technology and construction methods for exteriors of existing multi-story buildings has been slow.

[0003] To address this problem, existing technical solutions have proposed a structural form of installing photovoltaic brackets on the parapet. This structural form requires drilling holes in the parapet and inserting fixing rods in the holes, connecting the mounting frame through the fixing rods, and installing photovoltaic panels on the mounting frame. Although the installation of photovoltaic panels can be completed in this way, this structural form will weaken the bearing capacity and stability of the parapet, and the height of the parapet is limited, which in turn results in a small number of installed photovoltaic panels, that is, the electricity obtained through photovoltaics is limited; at the same time, after the photovoltaic panels are installed on the parapet through the mounting frame, the bearing capacity of the parapet is increased. When encountering severe weather (such as strong winds), the parapet structure may be damaged, and the photovoltaic equipment on the parapet may fall from a height, causing serious damage to pedestrians and equipment below the building. Summary of the Invention

[0027] The third connecting steel strand is connected to a fixed base, and the fixed base is fixed on the photovoltaic panel. The photovoltaic panel is adjusted between the first mounting components of two adjacent levels. After the control terminal in the control system obtains the photovoltaic panel from the unit controller to reach the preset position, it is fixed through the fixed base.

[0028] Compared with the prior art, the present invention has the following beneficial technical effects:

[0029] The present invention proposes a bracket for photovoltaic installation on the outside of an existing building. The bracket ensures that the bracket can remain stable in the face of various external factors through the combination of the corner connecting block and the second connecting steel strand, and the connection of the reinforcement rod between the first mounting components of the adjacent two levels, thereby providing a high-strength mounting bracket. The overall construction and installation are simple and light, and will not impose excessive load on the roof of the existing building. The second movable connecting block and the first fixing clamp in the second mounting component are connected by the third connecting steel strand, which not only increases the flexibility of the bracket and facilitates the installation and removal of the photovoltaic panel, but also makes the operation and maintenance of the photovoltaic bracket more convenient. The communication connection between the unit controller and the control terminal realizes real-time monitoring and remote control of the status of each component of the bracket, greatly reducing the operation and maintenance cost and improving the operation and maintenance efficiency. Through this bracket, photovoltaic panels can be installed on the entire outer surface of the building, increasing the number of photovoltaic panels installed on the outer side of the building and improving power generation efficiency. The second mounting component allows the photovoltaic panels to be installed or removed by sliding on the second vertical connecting steel strand, ensuring the convenience and safety of workers' operation.

[0030] Furthermore, the bracket is fixed to the top end surface of the building body at the corner of the parapet through an installation base, which ensures the stability and reliability of the suspension component, makes full use of the building space, and effectively avoids the impact of the bracket on the building appearance. The stability of the bracket support is increased by the suspension arm, and the sliding part allows the second connecting steel strand to slide freely along the guide rail on the suspension arm. The position of the second connecting steel strand can be adjusted according to the preset position, which improves the convenience of installation. The first drive motor is connected to the unit controller, and the installer can remotely control the position of the sliding part through the control terminal. The installer does not need to use tools to install it outside the building, which improves the safety of the installation.

[0031] Furthermore, in this bracket, the cooperation between the second drive motor and the unit controller can accurately control the moving position of the corner connecting block on the second connecting steel strand, thereby improving the convenience of the installation of the photovoltaic bracket and enabling the bracket to be fine-tuned as needed. During the installation process, the second drive motor and the unit controller are used to make the corner connecting block move along the second connecting steel strand, reducing the workload of the installers. This bracket allows photovoltaic panels to be installed on the entire outside of the building, increasing the number of installed photovoltaic panels and improving power generation efficiency.

[0032] Furthermore, the drive motor and screw rod of the fixed base in this bracket, combined with the third connecting steel strand, provide stable support and adjustment functions for the photovoltaic panel, reducing the installation difficulty for the installers during the installation process and speeding up the installation efficiency.

[0033] Furthermore, there are multiple reinforcement rods in this bracket, and the multiple reinforcement rods are located on the same side end face of the outer wall of the building. The two reinforcement rods in the first mounting components of the two adjacent levels are connected by a mosaic buckle, so that the two reinforcement rods form an "X"-shaped support structure. The "X"-shaped support structure increases the supporting strength of the first mounting components of the two adjacent levels, thereby increasing the wind resistance stiffness of the bracket, thereby preventing the bracket from colliding with the building body after being subjected to a large wind load.

[0063] The technical solution proposed in the present invention is only applicable to multi-story and high-rise buildings with rectangular structural shapes. The reason is that the oblique reinforcement rods 11 on the four building facades can provide wind-resistant stiffness for the bracket of the present application, that is, no matter from which angle the wind blows towards the bracket structure of the present application, the bracket structure of the present application will not undergo significant deformation.

[0064] The present invention proposes a method for installing a bracket for photovoltaic installation outside an existing building, comprising the following steps:

[0065] Install a suspension assembly 2 on the top end surface of the building body at the corner area of ​​the parapet 1, and vertically install a second connecting steel strand 6 on the suspension assembly 3;

[0066] Specifically, the bottom of the mounting base 20 is fixed to the top end surface of the building body at the corner position of the parapet 1, and the suspension arm 21 is installed on the mounting base 20. The bottom end surface of the suspension arm 21 is connected to one end of the second connecting steel strand 6, and the first controller and the first sensor in the unit controller are communicatively connected to the control terminal;

[0067] The control terminal in the control system controls the unit controller installed on the suspension assembly 2, and drives the suspension assembly 2 through the unit controller so that the second connecting steel strand 6 is parallel to the building facade and moves the second connecting steel strand 6 to a preset position;

[0068] Specifically, the control terminal in the control system obtains the position information collected by the first sensor, and the installer determines the preset position through the position information, and sends a control signal to the first controller through the control terminal to control the first drive motor 221 to start. The first drive motor 221 drives the roller 222 to rotate, so that the U-shaped sliding block 220 moves along the guide rail under the cooperation of the limit block 223 and the limit guide groove 211. During the movement, the position information is obtained in real time by the first sensor and sent to the control terminal. When the first sensor obtains in real time that the second connecting steel strand 6 moves to the preset position, the control terminal sends a control signal to the first controller, and the first controller controls the first drive motor 221 to stop, and at the same time controls the electric push rod 230 in the first locking member 23 to push the block 231 into the corresponding slot 212 to fix the position of the second connecting steel strand 6.

[0069] A plurality of corner connection blocks 40 are installed on each second connecting steel strand 6. The control system obtains the position of the corner connection blocks 40 through the unit controller and adjusts the position of the corner connection blocks 40 based on the position of the corner connection blocks 40 so that the plurality of corner connection blocks 40 are installed at equal intervals. A first connecting steel strand 5 is connected between two adjacent corner connection blocks 40 at the same height on different second connecting steel strands 6. The corner connection blocks 40 connected at the same height form a first installation assembly 4 of a first level.

[0070] Specifically, a plurality of corner connection blocks 40 are installed on each second connecting steel strand 6, and a unit controller, that is, a second controller and a second sensor, is installed on the corner connection block 40. A first connecting steel strand 5 is connected between two adjacent corner connection blocks 40 at the same height on different second connecting steel strands 6. The control terminal in the control system obtains the position information collected by the second sensor, and the installer determines the preset position through the position information. The control terminal sends a control signal to the second controller to control the second drive motor 410 to start, and the second drive motor 410 drives the drive wheel 411 to rotate, so that the corner connection block 40 moves to the preset position along the second connecting steel strand 6, and the multiple corner connection blocks 40 on the same second connecting steel strand 6 are arranged at equal intervals. When the second sensor obtains in real time that the corner connection block 40 moves to the preset position Afterwards, the control terminal sends a control signal to the second controller, and the second controller controls the second drive motor 410 to stop, and at the same time controls the rotating member 420 to drive the roller 421 to rotate, so as to retract and release the steel belt 422, so that the anti-slip protrusion 423 on the steel belt 422 is tightly fitted to the outer wall of the second connecting steel strand 6, thereby fixing the corner connecting block 40 on the second connecting steel strand 6; the first connecting steel strand 5 is connected to the first movable connecting block 7, and the first movable connecting block 7 is installed on the side end surface of the corner connecting block 40, and the corner 40 connecting blocks connected at the same height form a first-level mounting assembly 4, and the control terminal controls the third sensor to obtain the sagging information of the first connecting steel strand, and sends a control signal to the third controller based on the sagging information of the first connecting steel strand 5, so that the tightening motor 72 in the first movable connecting block works to tighten the first connecting steel strand 5;

[0071] Connect the reinforcement rods 11 to the first connecting steel strands 5 located on the same side of the building outer wall in the first mounting assemblies 4 of the two adjacent levels;

[0072] Specifically, two reinforcement rods 11 are connected to the first connecting steel strand 5 located on the outer wall of the same side of the building in the first installation assembly 4 of two adjacent levels. The center positions of the two reinforcement rods 11 are connected by an interlocking buckle 12, so that the two reinforcement rods 11 form an "X"-shaped support structure. The upper ends of the two reinforcement rods 11 are connected to a second fixing clamp 13, and the second fixing clamp 13 is fixed to the first connecting steel strand 5 to fix one end of the reinforcement rod 11. The other side ends of the two reinforcement rods 11 are connected to the first movable connecting block 7.

[0073] The two reinforcing rods 11 in the first installation component 4 near the bottom level of the building form an "X"-shaped support structure. During construction, construction workers are required to use a slender clamp to clamp the two end portions of the first connecting steel strand 5 in the first installation component 4 near the bottom level of the building, and apply a reverse force to cooperate with the first movable connecting block 7 to tighten the first connecting steel strand 5 in the first installation component 4 near the bottom level of the building. During the construction process, it is also necessary to note that the second connecting steel strand 6 should always remain vertical. Specifically, it can be judged by whether the projections of the position information obtained by the first sensor and the second sensor on the horizontal plane coincide with each other. If they coincide, it can be judged that the second connecting steel strand 6 remains vertical. In order to prevent the second connecting steel strand 6 from tilting after the first movable connecting block 7 in the first installation component 4 near the bottom level of the building tightens the first connecting steel strand 5.

[0074] The second-level first connecting steel strand 5, which is positioned from low to high, also requires construction workers to use a slender clamp to cooperate with the first connecting steel strand 5 to tighten it, and then install the second fixing clamp 13 after tightening. The specific installation of the second fixing clamp 13 can be achieved by construction workers standing on the edge of the parapet 1 with the help of tools. It is easy to operate and has low construction safety hazards, so that the "X"-shaped support structure of the lowest level can be stably formed. When the remaining "X"-shaped support structures are constructed, it is ensured that the second connecting steel strand 6 does not tilt.

[0075] A first fixing clamp 9 is connected to the first connecting steel strand 5 in the first installation component 4 close to the suspension component 2, and a second movable connecting block 8 is connected to the first connecting steel strand 5 in the first installation component 4 farthest from the suspension component 2. A third connecting steel strand 10 is connected between the second movable connecting block 8 and the first fixing clamp 9. A second installation component is formed by the first fixing clamp 10, the second movable connecting block 8 and the third connecting steel strand 10. The position of the second movable connecting block 8 is obtained by the fourth sensor on the second movable connecting block 8. The control terminal sends a control signal to the fourth controller based on the position of the second movable connecting block 8. The fourth controller controls the third drive motor 82 to start, and the third drive motor 82 drives the moving wheel 81 to move the second movable connecting block 8 to a preset position. Then the fourth controller controls the third drive motor 82 to stop, so that a photovoltaic panel 3 is stably installed 4 between the first installation components of two adjacent levels.

[0076] During construction, the first fixing clamp 9 also needs to be equipped with a sensor, and the first fixing clamp 9 and the fourth sensor of the second movable connecting block 8 need to cooperate simultaneously to ensure that the third connecting steel strand 10 is installed vertically.

[0077] The third connecting steel strand 10 is connected to the fixed base 14, and the fixed base 14 is fixed on the photovoltaic panel 3. The photovoltaic panel 3 is adjusted to between the first mounting assemblies 4 of two adjacent levels. After the control terminal in the control system obtains the information that the photovoltaic panel 3 has reached the preset position through the fifth sensor in the unit controller, the photovoltaic panel 3 is fixed between the first mounting assemblies 4 of two adjacent levels through the fixed base 14.

[0078] Specifically, a mounting seat 141 is installed on the photovoltaic panel 3, and the mounting seat 141 is connected to the fixing seat 144 through a screw rod 142, and the mounting seat 141 and the fixing seat 144 embrace the third connecting steel strand 10, and the control lock 15 is connected through a slender rod. The control terminal obtains the position of the photovoltaic panel 3 through the fifth sensor, and the installer pushes the slender rod to cooperate with the fixing seat 141 and the mounting seat 144 to embrace the third connecting steel strand 10, so that the photovoltaic panel 3 moves downward on the third connecting steel strand 10 and moves to between the first mounting components 4 of the two adjacent levels. At this time, the fifth sensor obtains that the position of the photovoltaic panel 3 reaches the preset position, and the control terminal sends a control signal to the fifth controller. The fifth controller controls the drive motor 143 to work, and the drive motor 143 drives the screw rod 142 to rotate, reducing the distance between the mounting seat 141 and the fixing seat 144, and tightly embraces the third connecting steel strand 10 with the mounting seat 141 and the fixing seat 144, thereby fixing the photovoltaic panel 3 on the third connecting steel strand 10.

[0079] The principle of the patent application is as follows: The bracket structure of the present application is not connected to the main body of the building. The overall control terminal uses GPS to control the movement of the corner connecting block 4, the first movable connecting block 7, the second movable connecting block 8, and the second connecting steel strand 6, thereby forming a bracket structure. The overall construction and installation are simple and light, and will not impose excessive load on the existing building roof. At the same time, the photovoltaic panel 3 is installed or removed by sliding on the second vertical connecting steel strand 10 by controlling the lock 15 and cooperating with the fixing seat 14, ensuring the convenience and safety of workers' operation. The installation of the present application does not require any workers to work outside the building outline, which can reduce construction risks.
