Description

Technical Field

[0001] This invention relates to the field of photovoltaic module installation technology in the desert region, specifically to a working platform and installation method suitable for photovoltaic module installation in the desert region. Background Technology

[0002] Photovoltaic module installation is one of the most complex and safety-critical aspects of photovoltaic power plant construction in the desert region. Its construction efficiency and operational safety directly determine the construction cycle, investment cost, and subsequent operational stability of the entire photovoltaic base. Unlike distributed photovoltaic projects in plains areas, the desert region is characterized by soft, easily collapsing ground, complex undulating dune terrain, frequent strong winds and sandstorms, extremely large work areas, harsh on-site construction environments, and high ecological protection requirements. These characteristics place extraordinary demands on the work platforms and construction techniques for photovoltaic module installation, significantly exceeding those of conventional scenarios. Conventional installation equipment and processes have revealed significant technical deficiencies under these conditions.

[0003] Currently, the mainstream construction method for photovoltaic module installation in the desert area is to use steel pipe scaffolding to build a working platform. This method involves setting up a fixed working surface on-site using steel pipe scaffolding to allow workers to complete the module installation. However, under the special working conditions of desert and Gobi areas, this process has inherent defects that are difficult to overcome: First, the efficiency of scaffolding erection and relocation is extremely low. The working area of ​​desert and Gobi projects can span several kilometers, and the spacing between pile foundations is dynamically adjusted according to the terrain. After the construction of each working area is completed, the workers must descend, dismantle and move the scaffolding, level the ground again, and re-erect and level it. The proportion of non-working time is extremely high, which cannot meet the construction requirements of "short construction period and high density" of large-scale photovoltaic bases. Second, the safety risks are prominent. The ground surface in desert and Gobi areas is soft, and the scaffolding legs are very easy to sink into the sand dunes, causing the scaffolding to tilt and become unstable, resulting in workers falling from heights. In addition, a special person must be arranged on the ground to stabilize the scaffolding throughout the operation, which not only occupies a lot of manpower, but also poses secondary safety hazards due to human-machine coordination errors. Third, the terrain adaptability is extremely poor. Facing the uneven terrain of undulating sand dunes, the scaffolding is difficult to level and cannot flexibly adapt to the installation requirements of different pile foundation heights and different working spans.

[0005] This invention provides a working platform suitable for installing photovoltaic modules in desert areas, including a suspension support mechanism, a working platform mechanism, and a climbing ladder mechanism: The suspension support mechanism includes at least two sets of suspension hooks. The upper end of the suspension hook forms a hooking part that is adapted to the already fastened photovoltaic bracket. The lower end of the suspension hook is fixedly connected to both sides of the work platform mechanism, which is used to suspend the entire work platform without ground support on the installed and fastened photovoltaic bracket. The work platform mechanism is a telescopic platform assembly, which includes multiple platform units that are nested together in sequence. A locking device is provided between adjacent platform units. The locking device is used to lock the relative position of adjacent platform units after the telescopic platform assembly is extended or retracted into place, so as to form a stable work bearing surface. The climbing ladder mechanism is a telescopic ladder assembly. The upper end of the telescopic ladder assembly is detachably and fixedly connected to the work platform mechanism, and the lower end of the telescopic ladder assembly extends downward in the vertical direction to form a safe passage for workers to go up and down the work platform.

[0006] The work platform provided by this invention completely solves the industry problem of soft ground and easy sinking of outriggers in desert areas through its foundation-free suspended load-bearing structure. The retractable and lockable work platform mechanism allows for flexible adaptation of the work span, eliminating the need for repeated scaffolding erection and dismantling, significantly reducing the proportion of non-working time and improving construction efficiency. The matching retractable ladder assembly provides a dedicated safe access route, avoiding the safety risks of workers falling from heights and preventing deformation and damage to the installed supports caused by climbing. Furthermore, once the platform is suspended, no ground personnel are required for continuous support, greatly reducing on-site manpower input and perfectly meeting the construction requirements of "short construction period, high density, and strict standards" for large-scale photovoltaic bases in desert areas.

[0007] In one optional embodiment, the suspension hook is integrally bent from a steel bar, and the hooking part is a downward-opening C-shaped hook body. The opening size of the C-shaped hook body is adapted to the cross-sectional size of the horizontal or vertical beam of the photovoltaic bracket, and an anti-slip buffer pad layer is provided on the inner side of the C-shaped hook body.

[0008] In one optional embodiment, the lower end of the suspension hook is welded and fixed to the end side beam of the telescopic platform assembly, and multiple sets of suspension hooks are symmetrically distributed along the length direction of the telescopic platform assembly, with the hooking part of each set of suspension hooks at the same horizontal height.

[0010] In one optional embodiment, the locking device includes a pin seat, a locking pin, and multiple sets of locking holes formed on the side wall of the platform unit. The pin seat is fixed to the outer platform unit in the adjacent platform units, and the locking pin is insertably inserted into the pin seat and the locking holes to achieve telescopic locking of the adjacent platform units.

[0011] In one optional embodiment, the telescopic ladder assembly includes multiple ladder units that are nested together in sequence, with a ladder locking member provided between adjacent ladder units, and the surface of the step bar of the ladder unit is provided with anti-slip texture.

[0012] In one optional embodiment, the upper end of the telescopic ladder assembly is provided with a connecting hook, and the side beam of the work platform mechanism is provided with a hooking hole adapted to the connecting hook. The connecting hook is hooked into the hooking hole and is provided with an anti-detachment pin, so as to realize the detachable fixation of the telescopic ladder assembly and the work platform mechanism.

[0013] Secondly, this embodiment also provides an installation method for photovoltaic modules suitable for the desert region, implemented using the aforementioned work platform for installing photovoltaic modules in the desert region. The installation method includes the following steps: Photovoltaic bracket pre-installation: Complete the installation and fastening of photovoltaic brackets within the target work area to form a load-bearing base that can be attached to the work platform; Platform mounting: The suspension hook of the suspension support mechanism is attached to the already secured photovoltaic bracket, so that the platform mechanism is horizontally suspended without ground support at the working surface where the photovoltaic modules are to be installed; Adjustment of the working platform: Adjust the telescopic length of the telescopic platform assembly according to the span of the working surface to be installed. After adjustment, lock it with the locking device to form a stable working bearing surface. Ladder installation and adjustment: The upper end of the telescopic ladder assembly is fixedly connected to the work platform mechanism. The length of the telescopic ladder assembly is adjusted according to the suspension height of the work platform to form a safe passage for going up and down. Photovoltaic module installation: Workers climb onto the work platform via a telescopic ladder assembly and complete the installation of photovoltaic modules on the corresponding work surface on the telescopic platform assembly; Work platform relocation: After completing the installation work on the current work surface, the workers descend to the ground via the telescopic ladder assembly, disconnect the suspension hook from the photovoltaic bracket, and transfer the work platform to the next work surface. The process is repeated to attach the work platform to the photovoltaic module installation work, thus completing the installation of photovoltaic modules in the entire area.

[0014] In one optional embodiment, during the work platform mounting step, the suspension hook is attached to the top crossbeam of the photovoltaic bracket, and after the attachment is completed, the attachment part of the suspension hook is locked to prevent detachment.

[0015] In one optional implementation, during the photovoltaic module installation process, when the operator is working on the work platform mechanism, no ground personnel are required to assist in supporting the work platform.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Photovoltaic module installation is one of the most complex and safety-critical aspects of photovoltaic power plant construction in the desert region. Its construction efficiency and operational safety directly determine the construction cycle, investment cost, and subsequent operational stability of the entire photovoltaic base. Unlike distributed photovoltaic projects in plains areas, the desert region is characterized by soft, easily collapsing ground, complex undulating dune terrain, frequent strong winds and sandstorms, extremely large work areas, harsh on-site construction environments, and high ecological protection requirements. These characteristics place extraordinary demands on the work platforms and construction techniques for photovoltaic module installation, significantly exceeding those of conventional scenarios. Conventional installation equipment and processes have revealed significant technical deficiencies under these conditions.

[0021] Currently, the mainstream construction method for photovoltaic module installation in the desert area is to use steel pipe scaffolding to build a working platform. This method involves setting up a fixed working surface on-site using steel pipe scaffolding to allow workers to complete the module installation. However, under the special working conditions of desert and Gobi areas, this process has inherent defects that are difficult to overcome: First, the efficiency of scaffolding erection and relocation is extremely low. The working area of ​​desert and Gobi projects can span several kilometers, and the spacing between pile foundations is dynamically adjusted according to the terrain. After the construction of each working area is completed, the workers must descend, dismantle and move the scaffolding, level the ground again, and re-erect and level it. The proportion of non-working time is extremely high, which cannot meet the construction requirements of "short construction period and high density" of large-scale photovoltaic bases. Second, the safety risks are prominent. The ground surface in desert and Gobi areas is soft, and the scaffolding legs are very easy to sink into the sand dunes, causing the scaffolding to tilt and become unstable, resulting in workers falling from heights. In addition, a special person must be arranged on the ground to stabilize the scaffolding throughout the operation, which not only occupies a lot of manpower, but also poses secondary safety hazards due to human-machine coordination errors. Third, the terrain adaptability is extremely poor. Facing the uneven terrain of undulating sand dunes, the scaffolding is difficult to level and cannot flexibly adapt to the installation requirements of different pile foundation heights and different working spans.

[0022] The following is combined Figures 1 to 2 The following describes embodiments of the present invention.

[0023] According to an embodiment of the present invention, in a first aspect, a working platform suitable for installing photovoltaic modules in desert areas is provided, comprising a suspension support mechanism, a working platform mechanism, and a climbing ladder mechanism. The suspension support mechanism includes at least two sets of suspension hooks 1, the upper end of which forms a hooking part adapted to the already fastened photovoltaic bracket, and the lower end of which is fixedly connected to both sides of the working platform mechanism, for suspending the entire working platform without ground support on the installed and fastened photovoltaic bracket. The working platform mechanism is a telescopic platform assembly, which includes multiple platform units 2 that are sequentially nested together. A locking device 4 is provided between adjacent platform units 2, which is used to lock the relative position of adjacent platform units 2 after the telescopic platform assembly is extended or retracted to its position, so as to form a stable working bearing surface. The climbing ladder mechanism is a telescopic ladder assembly 3, the upper end of which is detachably fixedly connected to the working platform mechanism, and the lower end of which extends downward in the vertical direction to form a safe passage for workers to go up and down the working platform.

[0024] This embodiment provides a working platform suitable for photovoltaic module installation in desert and Gobi areas. It can be applied to the installation and construction of photovoltaic modules in centralized photovoltaic power stations in desert, Gobi and arid areas, solving the problems of existing installation platforms being prone to ground support sinking, low relocation efficiency and high operational safety risks under special working conditions in desert and Gobi areas.

[0025] The work platform comprises three components: a suspension support mechanism, a work platform mechanism, and a climbing ladder mechanism. The suspension support mechanism includes at least two sets of suspension hooks 1. The upper end of each suspension hook 1 has a connecting part that is adapted to the already installed and secured photovoltaic support structure, enabling a stable connection. The lower end of each suspension hook 1 is fixedly connected to both sides of the work platform mechanism. The function of this suspension support mechanism is to suspend the entire work platform without ground support on the installed and secured photovoltaic support, ensuring that the entire load of the work platform is transferred to the photovoltaic support through the suspension hooks 1. This eliminates reliance on ground support and fundamentally avoids the problems of support structure subsidence and frame tilting instability caused by the soft ground surface in the desert region.

[0026] The working platform is a telescopic platform assembly. The telescopic platform assembly comprises multiple platform units 2 that are sequentially nested together, with locking devices 4 installed between adjacent platform units 2. During operation, the overlapping length of adjacent platform units 2 can be adjusted according to the lateral span requirements of the work surface to be installed, thereby achieving flexible adjustment of the overall length of the telescopic platform assembly. The locking devices 4 are used to lock the relative positions of adjacent platform units 2 after the telescopic platform assembly has been extended to the target working length, making the multiple nested platform units 2 form a rigid whole, providing a stable working surface for operators and meeting the standing and operation requirements for photovoltaic module installation.

[0027] The climbing mechanism is a telescopic climbing ladder assembly 3. The upper end of the telescopic climbing ladder assembly 3 is detachably and fixedly connected to the work platform mechanism, while the lower end extends vertically downwards, forming a safe passage for workers to move between the ground and the work platform mechanism. During operation, the overall length of the telescopic climbing ladder assembly 3 can be adjusted according to the suspension height of the work platform mechanism to accommodate different work heights. Workers can safely ascend and descend the work platform using this telescopic climbing ladder assembly 3 without needing to climb the photovoltaic support frame to complete the climbing operation.

[0028] The work platform provided in this embodiment solves the industry problem of soft ground and easy sinking of outriggers in the desert and Gobi areas through its foundation-free suspended load-bearing structure. The retractable and lockable work platform mechanism enables flexible adaptation of the work span, eliminating the need for repeated scaffolding erection and dismantling, reducing the proportion of non-working time, and improving construction efficiency. The matching telescopic ladder assembly 3 provides access to heights, avoiding the safety risk of workers falling from heights. At the same time, after the platform is suspended, no ground personnel are required to provide full support, reducing on-site manpower input and adapting to the construction requirements of "short construction period, high density, and strict standards" of large-scale photovoltaic bases in desert and Gobi areas.

[0029] In one embodiment, the suspension hook 1 is integrally bent from a steel bar, and the hook part is a downward-opening C-shaped hook body. The opening size of the C-shaped hook body is adapted to the cross-sectional size of the horizontal or vertical beam of the photovoltaic bracket, and an anti-slip buffer pad layer is provided on the inner side of the C-shaped hook body.

[0030] In this embodiment, the suspension hook 1 adopts a steel bar integral bending and forming, with no splicing or welding of the split connection structure. The overall structure has strong continuity and excellent tensile and bending load resistance. It can stably bear the overall static load of the work platform and the dynamic load during the operation process. It is suitable for the operation stability requirements under strong wind and sand and strong gusts in the desert area. The structure avoids the safety risk of fracture failure of the split connection parts.

[0031] The upper part of the hanging hook 1 is a downward-opening C-shaped hook. The opening size of the C-shaped hook is adapted to the cross-sectional size of the horizontal or vertical beam of the photovoltaic support, so that the C-shaped hook can be completely fastened to the outside of the horizontal or vertical beam of the photovoltaic support. The inner wall of the hook and the outer wall of the support form a stable fit, avoiding the problem of loosening of the connection and platform shaking caused by excessive gaps, ensuring the horizontal stability of the work platform in the connected state, and eliminating the safety hazard of hook slippage during operation.

[0032] An anti-slip buffer pad can be installed on the inner side of the C-shaped hook, completely covering the contact interface between the C-shaped hook and the photovoltaic support. This anti-slip buffer pad significantly increases the static friction between the C-shaped hook and the photovoltaic support, further limiting the sliding displacement of the hook along the length of the support in the attached state, thus improving the attachment reliability of the work platform under strong wind disturbances. Furthermore, it forms a flexible isolation layer between the metal C-shaped hook and the photovoltaic support, preventing direct contact and friction between the metal hook and the support during attachment and relocation, protecting the galvanized anti-corrosion layer on the photovoltaic support surface. This solves the problem of existing suspended hangers easily wearing down the anti-corrosion layer of the support, leading to rapid corrosion and failure of the support in harsh desert environments.

[0033] In one embodiment, the lower end of the suspension hook 1 is welded and fixed to the end side beam of the telescopic platform assembly, and multiple sets of suspension hooks 1 are symmetrically distributed along the length direction of the telescopic platform assembly, with the hooking part of each set of suspension hooks 1 at the same horizontal height.

[0034] In this embodiment, the lower end of the suspension hook 1 is welded and fixed to the end side beam of the telescopic platform assembly. This welding method creates a rigid, integrated connection between the suspension hook 1 and the telescopic platform assembly, eliminating the gaps associated with separate connections. This allows the overall load of the work platform to be evenly and continuously transferred to the photovoltaic support via the suspension hook 1. It avoids the risks of loosening, detachment, and corrosion that can occur with detachable connections such as bolts and clips under strong winds, gusts, and continuous dynamic loads in desert environments, thus improving the long-term reliability and operational safety of the suspension support structure. Furthermore, the welded structure eliminates the need for on-site assembly of connectors, further simplifying the on-site construction process and improving work preparation efficiency.

[0035] In this embodiment, multiple sets of suspension hooks 1 are symmetrically distributed along the length of the telescopic platform assembly. This symmetrical arrangement design ensures that the self-weight load of the telescopic platform assembly, as well as the working load of personnel and materials, are evenly distributed to each set of suspension hooks 1, avoiding the problems of platform tilting due to concentrated load on one side and local hook overload breakage. Even if the personnel move along the length of the telescopic platform assembly, the symmetrically distributed multiple sets of suspension hooks 1 can always maintain the overall force balance of the platform.

[0036] In this embodiment, the attachment points of each set of suspension hooks 1 are at the same horizontal height. This design ensures that after all suspension hooks 1 have completed the attachment operation, the telescopic platform assembly can always remain horizontal, eliminating the safety hazards of workers slipping or falling due to uneven platform height, and providing a stable operating base for photovoltaic module installation. At the same time, the attachment points at the same horizontal height ensure that all suspension hooks 1 are subjected to force synchronously and evenly, avoiding the problem of individual hooks being overloaded and other hooks being loosely connected and not under load due to inconsistent attachment heights. This maximizes the load-bearing capacity of multiple sets of suspension hooks 1 and is suitable for long-term operation needs in the harsh working conditions of desert areas.

[0037] In one embodiment, the platform unit 2 is formed by welding galvanized square tubes to form a frame structure, and the upper surface of the frame structure is fixed with an anti-slip and wear-resistant tread. In the adjacent platform units 2, the platform unit 2 with a larger inner diameter is sleeved on the outer periphery of the platform unit 2 with a smaller inner diameter, and a sliding guide structure is provided between the two.

[0038] In this embodiment, platform unit 2 is constructed using galvanized square tubing welded together to form a frame structure. The galvanized square tubing substrate possesses the core characteristics of high strength and low weight. The welded frame structure forms a closed, rigid load-bearing system, capable of stably supporting the loads of workers, installation tools, and photovoltaic modules. Simultaneously, it meets the lightweight load-bearing requirements of suspended work platforms, avoiding excessive load on the suspension support mechanism. The galvanized anti-corrosion layer on the surface of the square tubing effectively resists corrosion and wear caused by strong winds, intense ultraviolet radiation, and high salinity in the Gobi Desert region, significantly extending the service life of platform unit 2 and meeting the long-term reusability requirements under harsh outdoor conditions in the Gobi Desert region.

[0039] The upper surface of the frame structure is fixed with anti-slip and wear-resistant treads, which completely cover the working area of ​​the upper surface of the frame structure, providing workers with a continuous and flat standing operating surface. The anti-slip design of the treads effectively avoids the risk of workers slipping and falling due to sand and sand falling on the tread surface during operations in desert areas; its wear-resistant properties can withstand the wear and tear caused by high-frequency personnel movement and the placement of tools and materials, ensuring the stability and safety of the working surface during long-term use, and solving the problem of existing simple suspended platforms that use photovoltaic brackets as footholds and are prone to falling due to insufficient support.

[0040] In adjacent platform units 2, the platform unit 2 with a larger inner diameter is nested around the outer periphery of the platform unit 2 with a smaller inner diameter, forming a nested telescopic fit structure. This nested design allows multiple platform units 2 to be smoothly telescopically adjusted along the axial direction, quickly adapting to installation requirements with different pile spacings and different working spans without disassembly and reassembly. At the same time, the platform unit 2 in the retracted state can significantly reduce the overall length, reduce the transport volume of the working platform, and adapt to the frequent relocation needs of the large photovoltaic base in the desert with a span of several kilometers, solving the problems of traditional steel pipe scaffolding being unable to telescopic and requiring repeated assembly and disassembly for relocation.

[0041] A sliding guide structure can be provided between two adjacent platform units 2, extending along the extension and retraction direction of the platform units 2. This sliding guide structure can precisely limit the extension and retraction movement of adjacent platform units 2, avoiding problems such as platform unit 2 tilting or jamming during the extension and retraction adjustment process. Even if sand and dust from desert areas enter the interlocking gap, the smoothness of the extension and retraction adjustment can still be guaranteed. At the same time, the sliding guide structure can limit the radial movement and swaying of adjacent platform units 2, further improving the overall rigidity and stability of the platform assembly after extension and retraction, ensuring that there is no significant shaking of the platform during operation, and providing a stable operating environment for photovoltaic module installation.

[0042] Specifically, the sliding guide structure is illustrated as follows: Linear guide rails are fixedly installed along the entire length of the platform unit 2 in the middle of the outer walls on both sides of the inner platform unit 2 (small inner diameter square tube frame). The length of the linear guide rails matches the maximum extendable stroke of the inner platform unit 2. Sliding sliders adapted to the linear guide rails are fixedly installed at corresponding positions on the inner walls on both sides of the outer platform unit 2 (large inner diameter square tube frame). The sliders are fitted onto the outer circumference of the linear guide rails, forming a sliding fit along the extension direction. Limiting blocks are provided at both ends of the linear guide rails to prevent the sliders from dislodging from the guide rails during extension.

[0043] In one embodiment, the locking device 4 includes a pin seat, a locking pin, and multiple sets of locking holes opened on the side wall of the platform unit 2. The pin seat is fixed to the outer platform unit 2 in the adjacent platform unit 2, and the locking pin is inserted and removed through the pin seat and the locking holes to realize the telescopic locking of the adjacent platform unit 2.

[0044] In this embodiment, the locking device 4 includes a pin seat, a locking pin, and multiple sets of locking holes. The three work together to form a telescopic locking structure that can be operated quickly, adapting to the needs of rapid adjustment and stable locking of the platform span in photovoltaic installation operations in the desert area.

[0045] The pin holder is fixed to the outer platform unit of the adjacent platform unit 2, specifically to the end sidewall of the outer platform unit 2 near the socket opening. The pin holder has a through hole adapted to the outer diameter of the locking pin. The axis of this through hole is perpendicular to the extension / retraction direction of the platform unit 2, providing stable insertion support and positioning reference for the locking pin. Multiple sets of locking holes are formed on the sidewall of the inner platform unit of the adjacent platform unit 2. These locking holes are evenly spaced along the extension / retraction direction of the inner platform unit 2. The diameter of each locking hole is adapted to the outer diameter of the locking pin, and the axis of the locking hole is parallel to the axis of the through hole on the pin holder. This allows the inner platform unit 2 to move with the extension / retraction of the inner platform unit 2, forming a coaxial alignment with the through hole of the pin holder.

[0046] The locking pin is a rigid columnar structure that can be inserted and removed into the through hole and the aligned locking hole of the pin seat. When it is necessary to adjust the working length of the telescopic platform assembly, the locking pin is pulled out from the locking hole and the pin seat, releasing the position lock of the adjacent platform unit 2. The inner platform unit 2 can move freely in the telescopic direction to achieve the adjustment of the overall length of the platform. When the telescopic platform assembly is adjusted to the target working length and the through hole of the pin seat and the corresponding locking hole are coaxially aligned, the locking pin is inserted into the through hole and the corresponding locking hole of the pin seat in sequence. This completely restricts the relative telescopic displacement of the adjacent platform units 2, locking the multiple platform units 2 into a rigid whole and forming a stable working bearing surface.

[0047] In one embodiment, the telescopic ladder assembly 3 includes multiple ladder units that are nested together in sequence, with ladder locking components provided between adjacent ladder units, and the surface of the ladder unit's treads being provided with anti-slip textures.

[0048] In this embodiment, the telescopic ladder assembly 3 includes multiple ladder units nested together in sequence. Each ladder unit includes two parallel vertical side beams and multiple treads fixed at equal intervals along the length of the side beams. The two ends of the treads are rigidly connected vertically to the two side beams respectively, forming an integrated closed ladder frame structure with excellent vertical load-bearing capacity and anti-lateral sway performance. In adjacent ladder units, the side beam of the ladder unit with a larger inner diameter is fitted around the outer periphery of the side beam of the ladder unit with a smaller inner diameter, forming a nested vertical telescopic cooperation structure. The overall length of the ladder assembly can be smoothly adjusted in the vertical direction without disassembly and reassembly, flexibly adapting to the passage requirements of work platforms with different suspension heights. In the retracted state, the multiple ladder units can be completely nested and overlapped, significantly reducing the overall vertical size of the ladder and the transfer volume, adapting to the long-distance, high-frequency relocation operation requirements of the large photovoltaic base in the desert. The ladder unit is made of galvanized steel, which can effectively resist corrosion and wear caused by strong winds, strong ultraviolet rays, and high salinity in the Gobi Desert, ensuring the structural strength and service life for long-term outdoor use.

[0049] Ladder locking devices are installed between adjacent ladder units, such as existing ball-pin type ladder locking devices or clamp-type tightening ladder locking devices. These locking devices lock the relative positions of adjacent ladder units after the telescopic ladder assembly 3 is adjusted to the target working length, completely restricting their vertical telescopic displacement. During operation, once the ladder assembly has been telescopically adjusted according to the suspension height of the work platform, the operator can quickly lock it using the ladder locking devices. This ensures that the multi-section ladder units form a rigid, continuous overall ladder frame, preventing the ladder units from shifting or swaying during the climb, thus guaranteeing stability and safety. Unlocking the ladder locking devices allows for quick adjustment of the overall length of the ladder assembly. The entire operation requires no additional tools, adapting to the rapid construction pace required on photovoltaic project sites.

[0050] The ladder unit features anti-slip textured surfaces on its treads, extending continuously along the axial direction to completely cover the entire working surface. This texture significantly increases the static friction between the worker's shoes and the treads, greatly enhancing safety when ascending and descending the work platform. The anti-slip texture is manufactured using a one-piece roll forming process, forming a unified structure with the tread base. It eliminates the need for additional adhesive or welded components that could easily detach, exhibiting excellent wear resistance. This allows it to withstand the wear and tear from frequent climbing and treading, ensuring consistent anti-slip performance over long-term use, perfectly meeting the needs of the large-scale, long-term construction of the Shagohuang photovoltaic project.

[0051] This embodiment utilizes a nested telescopic ladder unit structure to achieve flexible adjustment of the overall ladder length, perfectly adapting to the dynamic changes in the suspension height of the work platform caused by the undulating terrain in desert areas. The ladder locking mechanism enables rapid and stable locking of the telescopic state, ensuring structural rigidity and safety during climbing. The anti-slip texture on the step surface specifically addresses the safety concern of slipping during climbing in the windy and sandy environment of desert areas, providing workers with a safe, convenient, and reliable dedicated passage to ascend and descend the work platform. This completely avoids the safety hazards and support deformation damage problems caused by climbing photovoltaic supports to ascend and descend the work surface in existing technologies.

[0052] In one embodiment, the upper end of the telescopic ladder assembly 3 is provided with a connecting hook, and the side beam of the work platform mechanism is provided with a hooking hole adapted to the connecting hook. The connecting hook is hooked into the hooking hole and is provided with an anti-detachment pin, so as to realize the detachable fixation of the telescopic ladder assembly 3 and the work platform mechanism.

[0053] In this embodiment, the connecting hook is made of rigid metal material and is rigidly fixed to the vertical load-bearing structure at the upper end of the telescopic ladder assembly 3 to form an integrated hanging load end; the hook body structure of the connecting hook is adapted to the hanging point of the working platform mechanism, which can realize tool-free quick hanging assembly, and is suitable for the working scenario in the desert area where there are no supporting construction auxiliary conditions.

[0054] The side beams of the work platform mechanism are provided with mounting holes that are compatible with the connecting hooks. The mounting holes are through holes that run along the thickness direction of the side beams, and their diameter is compatible with the outer diameter of the hook rod of the connecting hook. Multiple sets of mounting holes and connecting hooks are arranged in a one-to-one correspondence and symmetrical arrangement to ensure that the vertical load of the telescopic ladder assembly 3 can be evenly transferred to the main structure of the work platform mechanism after mounting, avoiding structural deformation and shaking caused by unilateral load.

[0055] The connecting hook is attached to the hook hole and equipped with an anti-detachment pin to achieve detachable fixing of the telescopic ladder assembly 3 and the work platform mechanism. The specific assembly and limiting method is as follows: During on-site assembly, the hook end of the connecting hook is inserted into the corresponding hook hole, so that the hook body and the side beam of the work platform mechanism form a stable load-bearing hook engagement, completing the initial positioning of the telescopic ladder assembly 3 and the work platform mechanism; after being hooked in place, the anti-detachment pin is inserted into the preset radial limiting through hole on the connecting hook. After being inserted, the anti-detachment pin is located on the outside of the side beam of the work platform mechanism, which can completely limit the displacement of the connecting hook along the direction of detachment from the hook hole, forming double anti-detachment protection.

[0056] The detachable fixing structure provided in this embodiment is designed for the special working conditions of photovoltaic installation operations in desert areas. The disassembly and assembly operations are convenient and efficient. Operators can assemble and disassemble the telescopic ladder assembly 3 and the work platform mechanism by hand without the need for any additional tools. This greatly shortens the on-site construction preparation time and perfectly adapts to the construction needs of large-scale photovoltaic bases with high-frequency relocation and fast-paced progress.

[0057] According to an embodiment of the present invention, in a second aspect, an installation method for photovoltaic modules suitable for the desert region is provided, which is implemented using a work platform suitable for installing photovoltaic modules in the desert region. The installation method includes the following steps: Photovoltaic bracket pre-installation: Complete the installation and fastening of photovoltaic brackets within the target work area to form a load-bearing base that can be attached to the work platform; In response to the challenging conditions of the desert region, characterized by undulating sand dunes, soft ground, and severe wind erosion, the project team completed the positioning and layout of photovoltaic (PV) brackets within the target work area, pile foundation construction, main bracket assembly, and full-point fastening operations according to the design drawings. The team controlled the verticality, horizontality, and fastener torque of the PV brackets to ensure that all pre-installed PV brackets met the design load-bearing requirements, forming a stable and reliable load-bearing base. This provided qualified mounting points for subsequent platform installations, preventing the risk of instability due to inadequate fastening of the brackets.

[0058] Platform mounting: The suspension hook 1 of the suspension support mechanism is attached to the photovoltaic bracket that has been tightened, so that the platform mechanism is horizontally suspended without ground support at the working surface where the photovoltaic modules are to be installed; After the photovoltaic support bracket is pre-installed and passes inspection, the suspension hooks 1 of the work platform's suspension support mechanism are attached to the corresponding load-bearing points of the already secured photovoltaic support bracket. During the attachment process, it is ensured that all suspension hooks 1 form a stable and effective attachment with the photovoltaic support bracket, without any loose connections, uneven loads, or unilateral force. After attachment, the entire work platform mechanism achieves horizontal suspension without ground support through the suspension hooks 1. All the load of the work platform is transferred to the photovoltaic support bracket through the suspension hooks 1, completely independent of the soft ground surface of the desert area for support, avoiding the core safety hazards of traditional scaffolding leg sinking and frame tilting. At the same time, the suspension height of the work platform mechanism is precisely matched with the working surface height of the photovoltaic modules to be installed, adapting to the standing installation operation needs of the workers.

[0059] Adjustment of the working platform: Adjust the telescopic length of the telescopic platform assembly according to the span of the working surface to be installed. After adjustment, lock it with locking device 4 to form a stable working bearing surface. Based on the lateral span of the work surface to be installed, i.e., the design spacing between adjacent pile foundations and adjacent photovoltaic supports in the Shagohuang photovoltaic project, the overall telescopic length of the telescopic platform assembly is adjusted to ensure that the platform's horizontal work coverage fully matches the component installation requirements of the current work surface. After adjustment and when the platform length reaches the target work value, the relative positions of adjacent platform units 2 are locked using the locking device 4 between them, completely restricting the telescopic displacement of platform units 2. This allows the multi-section interlocking platform units 2 to form a rigid integral structure, providing a stable and undulating work surface for workers and preventing the platform from telescopically shifting or swaying during operation, thus ensuring the stability of the work process.

[0060] Ladder installation and adjustment: The upper end of the telescopic ladder assembly 3 is fixedly connected to the work platform mechanism. The length of the telescopic ladder assembly 3 is adjusted according to the suspension height of the work platform to form a safe passage for going up and down. After adjusting and locking the work platform, the upper end of the telescopic ladder assembly 3 is fixedly connected to the work platform mechanism to ensure a stable and reliable connection without the risk of loosening or displacement. Then, based on the current suspension height of the work platform mechanism, the overall length of the telescopic ladder assembly 3 is adjusted so that the lower end of the ladder extends close to the ground, forming a continuous and complete safe passage for workers to ascend and descend between the ground and the work platform mechanism. This eliminates the need for workers to climb the photovoltaic support frame to perform height operations, avoiding the risk of falls and preventing deformation or damage to the installed support frame.

[0061] Photovoltaic module installation: Operators climb onto the work platform via the telescopic ladder assembly 3 and complete the photovoltaic module installation work on the corresponding work surface on the telescopic platform assembly; Workers, carrying installation tools and the photovoltaic modules to be installed, safely ascend the work platform via the telescopic ladder assembly 3. On the locked working surface of the telescopic platform assembly, they carry out the entire installation process, including moving, aligning, fastening, and wiring the photovoltaic modules within the corresponding work area. During the operation, workers can move freely horizontally on the telescopic platform assembly without frequently climbing up and down the platform or adjusting their work positions. This allows for the continuous installation of multiple photovoltaic modules within the current work area, significantly reducing non-working time and improving overall construction efficiency.

[0062] Work platform relocation: After completing the installation work on the current work surface, the workers descend to the ground via the telescopic ladder assembly 3, disconnect the suspension hook 1 from the photovoltaic bracket, and transfer the work platform to the next work surface. The process is repeated to attach the work platform to the photovoltaic module installation work, thus completing the installation of photovoltaic modules in the entire area.

[0063] In one embodiment, during the platform mounting step, the suspension hook 1 is attached to the top crossbeam of the photovoltaic bracket, and after the attachment is completed, the attachment part of the suspension hook 1 is locked to prevent detachment.

[0064] In one embodiment, during the photovoltaic module installation process, when the operator is working on the work platform mechanism, no ground personnel are required to assist in supporting the work platform. The operator can move horizontally on the locked telescopic platform assembly to complete the continuous installation of multiple sets of photovoltaic modules.

[0065] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
