Description

Technical Field

[0001] This invention relates to the field of mobile home technology, and in particular to a photovoltaic box-type mobile home for multiple users. Background Technology

[0002] Prefabricated modular houses are widely used as temporary buildings in scenarios involving multiple users, such as field operations and emergency resettlement. The integration of photovoltaic systems further enhances their energy self-sufficiency.

[0003] Traditional photovoltaic mobile houses have many drawbacks. The solar panels, which are the main source of electricity, are easily covered by snow in rainy or snowy weather, causing a sharp drop in power generation efficiency or even stopping operation. Currently, there is a lack of low-power automatic snow removal solutions that are integrated with the building structure. Manual cleaning is usually required, which poses safety hazards and is inefficient. The steel structure is mostly fixed by welding or bolts, and the disassembly and assembly process is cumbersome and cannot meet the needs of rapid relocation. Exposed metal connectors are susceptible to rust from rainwater, making disassembly difficult and reducing service life. Cleaning and maintaining the surface of the solar panels is difficult, affecting power generation efficiency and posing risks of working at height. Therefore, we propose a photovoltaic box-type mobile house for multiple users. Summary of the Invention

[0008] As a preferred embodiment of the present invention, the fuel injection structure includes a fuel injector fixedly installed on the side of a sliding fuel reservoir, the interior of the fuel injector being in communication with the interior of the sliding fuel reservoir, two fuel injection pipes fixedly installed at the output end of the fuel injector, a fixed pressure sensor being provided on the side of the fuel injector, and a fixing block being fixedly installed on the upper side of the fixing rod, the fixing block being an "L" shaped block.

[0009] As a preferred embodiment of the present invention, a first mounting cavity is provided on one side of each of the two corresponding support columns. One end of the limiting column extends into the interior of the first mounting cavity. A threaded hole is provided on the bottom side of the limiting column. A rotating screw is threaded into the threaded hole on the bottom side of the limiting column. The rotating screw has a "T" shaped cross-section.

[0012] As a preferred embodiment of the present invention, a guide plate is fixedly installed on the side of the beam frame, a second guide groove is provided on the side of the guide plate, a guide rod is fixedly installed on the upper side of the sliding block, passing through the guide cavity and the second guide groove, a rack is fixedly installed on the side of the guide rod, and a gear sleeve that meshes with the rack is fixedly installed on the side of the rotating tube corresponding to the position of the rack.

[0013] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. A sliding oil reservoir, mounted above a fixed rod and slidable along an electric sliding track, along with a sliding block driven by a guide block on its side and sliding on a connecting plate, provides a reciprocating motion source for the snow removal system without additional power. The sliding block, through its guide rod and rack, meshes with a gear sleeve on the rotating tube. This allows the sliding oil reservoir to synchronously drive the rack to reciprocate during maintenance movements, such as triggering lubrication of the injector. This, in turn, drives the gear sleeve and rotating tube to periodically rotate in both directions. Compressed air is introduced into the connecting tube, or airflow is introduced and ejected through spray holes on the side of the rotating tube. The rotating spray holes sweep the airflow across the surface of the solar cell structure, effectively removing loose snow and achieving automated cleaning of light daily snow accumulation. For thick snow accumulation... In the event of snow or ice, a rotating motor drives a threaded rod, which in turn moves a movable block and groove fixed to the snowplow along the path limited by the obstruction block, causing the snowplow to scrape away the snow. During this process, the continuously rotating tube simultaneously drives the knocking brush, which is slidably mounted on its side, to rotate and move downward. The rotating knocking brush continuously impacts and scrapes the ice layer on the surface of the solar cell structure, achieving mechanical ice breaking. This invention achieves full-scene snow and ice removal functions, from blowing away loose snow and scraping thick snow to breaking ice layers, by integrating the sliding oil storage box and guide block of the maintenance lubrication component's motion mechanism with the rack, gear sleeve, rotating tube of the snow removal actuator, and the snowplow and knocking brush of the powerful ice removal mechanism. This greatly ensures the continuity of power generation of the photovoltaic system under severe weather conditions, and the structure is compact, energy-efficient, and highly automated.

[0014] 2. This invention achieves rapid positioning and stable assembly of the prefabricated house through a modular design of the installation frame, support columns, installation boxes, and installation blocks. The installation frame serves as the load-bearing foundation, and its internal "U"-shaped installation rack can quickly lay the installation plate to form a complete base plate. The support columns are fixed to the upper side of the installation frame. Vertical support is achieved by directly fitting the installation box with its lower opening onto the top of the corresponding support column. The "L"-shaped installation block is snapped onto the top of the installation box to achieve lateral positioning. The "T"-shaped positioning column passes through the third guide hole, the second guide hole, and the first guide hole in sequence to achieve precise vertical positioning. This modular snap-fit ​​design allows the prefabricated house frame to be initially assembled without professional tools. The components work together to form a clear force transmission path, laying the foundation for subsequent fastening operations and significantly improving assembly efficiency and initial stability. It is particularly suitable for multi-user scenarios that require frequent relocation.

[0015] 3. This invention achieves integrated and efficient fastening of the entire frame of the prefabricated house through the synergistic action of threaded columns, locking threaded holes, locking nuts, and extrusion structures. This fastening mechanism uses threaded columns to rotate downwards within the locking threaded holes of the fixing rods. The inner ring block and outer ring sleeve push the first connecting block, causing the connecting plate to press down on the mounting block. Simultaneously, the locking nut on the threaded column is tightened. The extrusion connecting rod drives the extrusion structure composed of the second connecting block and the rotating screw, powerfully pulling all the "T"-shaped limit columns downwards synchronously. The two actions together form a uniformly distributed vertical clamping force. Through the force transmission path from the connecting plate to the mounting block to the mounting box to the support column, all modules are tightly locked into a high-rigidity whole, greatly enhancing the structural stability and safety performance of the prefabricated house under multiple users and in severe weather conditions.

[0016] 4. This invention effectively solves the problem of rust prevention and maintenance of key connection parts through an automatic lubrication system consisting of a sliding oil reservoir, an oil injector, an oil injection pipe, and a pressure sensor. The sliding oil reservoir moves within the electric sliding groove of the fixed rod. When the pressure sensor on its side contacts the "L"-shaped fixed block, it automatically triggers the oil injector, which precisely sprays lubricating oil to two key parts through two oil injection pipes: the threaded engagement between the threaded column and the locking threaded hole, and the movable connection between the inner ring block and the outer ring sleeve. This fixed-point automatic lubrication can form a protective oil film on the metal surface, effectively isolating air and moisture, and preventing the threaded pair and rotating joint from rusting and seizing due to long-term exposure. This design not only extends the service life of the core connection parts, but also ensures that each component can be easily disassembled when relocation and maintenance are required, significantly reducing maintenance difficulty and long-term operating costs.

[0017] 5. This invention achieves efficient and automated cleaning of solar cell structures through the linkage design of sliding blocks, cleaning brushes, guide blocks, and sliding oil storage boxes. The cleaning brushes are fixed at equal intervals on the side of the sliding blocks, and the sliding blocks are rigidly connected to the sliding oil storage boxes through the guide blocks. When the sliding oil storage boxes perform lubrication tasks and move on the electric slide, they synchronously drive the guide blocks and sliding blocks to move, causing the cleaning brushes to sweep across the surface of the solar cell structure, effectively removing dust, leaves, and other debris. This ingenious mechanical linkage allows photovoltaic module cleaning to be completed automatically during routine maintenance without additional power equipment or manual intervention, significantly improving the power generation efficiency of the solar cell structure and avoiding the risks and maintenance costs of high-altitude operations for specialized cleaning.

[0018] 6. This invention achieves precise positioning and reinforced locking of the prefabricated house through the cooperation of the "T"-shaped limiting post, connecting rod, and the compression structure composed of the second connecting block and rotating screw. The cooperation between the "T"-shaped limiting post and the "T"-shaped third guide hole completely restricts the movement between the mounting block and the mounting box in the horizontal direction, ensuring the precise alignment of the upper structure. The connecting rod connects the limiting posts on both sides into an integral frame, so that the locking force is evenly distributed. When the locking nut presses the connecting rod, the force is converted into a downward pulling force on the limiting post through the second connecting block and rotating screw. This force not only further presses the contact surface between the mounting block and the mounting box, but also generates huge static friction between the limiting post and the walls of each guide hole, completely eliminating vertical displacement gaps. This multi-dimensional constraint mechanism combining horizontal limiting and vertical locking greatly enhances the node stiffness and improves the wind and earthquake resistance of the overall structure, providing a reliable guarantee for the long-term safe use of the prefabricated house in complex environments.

[0021] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0022] Example: Figures 1 to 10As shown in the figure, a photovoltaic box-type movable house for multiple people to use includes an installation frame 111. Six fixed support columns 112 are provided on the upper side of the installation frame 111. Removable installation boxes 211 are provided on two mutually corresponding support columns 112. Two installation blocks 311 are provided above one installation box 211. A fixed roof beam frame 313 is provided between the four installation blocks 311. A fixed solar cell structure 315 is provided above the roof beam frame 313. A fixed connecting plate 314 is provided between two mutually corresponding installation blocks 311. A fixed fixing rod 246 is provided between two mutually corresponding support columns 112. A locking threaded hole 214 is opened at the middle position of the fixing rod 246. A fixed first connecting block 221 is provided at the bottom side of the connecting plate 314. A threaded column 222 is movably installed below the first connecting block 221. The threaded column 222 is threadedly connected inside the locking threaded hole 214. An electric chute is opened above the fixing rod 246. A sliding oil storage box 241 is slidably installed in the electric chute above the fixing rod 246. An oil spraying structure is provided at the output end of the sliding oil storage box 241. A snow removing structure is slidably provided above the connecting plate 314. A third guiding hole 312 is opened on the upper side of the installation block 311. The third guiding hole 312 is a "T" - shaped hole. A second guiding hole 212 is opened at the position corresponding to the third guiding hole 312 on the upper side of the installation box 211. A first guiding hole 114 is opened at the upper end of the support column 112. A limiting column 231 is provided inside the third guiding hole 312, the second guiding hole 212 and the first guiding hole 114. The limiting column 231 is a "T" - shaped column. An extrusion structure for driving the limiting column 231 to move downward is provided on the side surface of the limiting column 231. A "hui" - shaped installation frame is fixedly installed inside the installation frame 111. A number of installation plates 113 are equidistantly installed above the installation frame inside the installation frame 111.

[0023] More specifically, during use, the mounting frame 111 and support column 112 are transported to a suitable position using a crane. The mounting box 211 is then installed above the two corresponding support columns 112. After the two mounting boxes 211 are installed, the mounting block 311 and the roof beam frame 313 are assembled above the two mounting boxes 211. The threaded column 222 is rotated inside the locking threaded hole 214, and the limiting column 231 is inserted into the third guide hole 312, the second guide hole 212, and the first guide hole 114 to determine the overall position of the prefabricated house. As the threaded column 222 rotates inside the locking threaded hole 214, it moves downwards, carrying the first connecting block 221 and the connecting plate 314 downwards. The connecting plate 314, along with the mounting block 311, presses against the mounting box 211, which in turn presses against the support column 112 for fastening. Simultaneously, the pressing structure drives the limiting column 231 downward, ensuring that the limiting column 231 always has a downward force to improve the effect. When maintenance is required, the sliding oil storage box 241 is moved. Once the sliding oil storage box 241 is in the appropriate position, the oil spraying structure is activated. The oil spraying structure sprays oil onto the movable connection between the first connecting block 221 and the threaded column 222, as well as the threaded connection between the threaded column 222 and the locking threaded hole 214, to achieve rust prevention and facilitate the disassembly of the entire mobile house. The mounting plates 113 are then evenly arranged in the "U"-shaped mounting frame inside the mounting frame 111 for flooring installation.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, specifically, the mounting box 211 is a rectangular box with an opening at the bottom, and the mounting block 311 is an "L"-shaped block and is positioned above the mounting box 211.

[0025] More specifically, a mounting box 211 is supported by two support columns 112, the lateral movement of the mounting block 311 is restricted by locking the mounting block 311 above the mounting box 211, and the longitudinal movement of the mounting block 311 is constrained by passing a limiting column 231 through the interior of the third guide hole 312, the second guide hole 212 and the first guide hole 114.

[0026] like Figure 5 and Figure 6As shown, specifically, the fuel injection structure includes a fuel injector 242 fixedly installed on the side of the sliding fuel reservoir 241. The interior of the fuel injector 242 is connected to the interior of the sliding fuel reservoir 241. Two fuel injection pipes 243 are fixedly installed at the output end of the fuel injector 242. The two fuel injection pipes 243 are distributed in a "V" shape. A fixed pressure sensor 244 is provided on the side of the fuel injector 242. A fixing block 245 is fixedly installed on the upper side of the fixing rod 246. The fixing block 245 is an "L" shaped block.

[0027] More specifically, the sliding oil reservoir 241 slides above the fixed rod 246. When the sliding oil reservoir 241 slides with the oil injector 242 and the pressure sensor 244, the pressure sensor 244 presses against the fixed block 245, causing the oil injector 242 to spray the lubricating oil inside the sliding oil reservoir 241 through the two oil injection pipes 243 to the connection between the threaded post 222 and the locking threaded hole 214, as well as the connection between the inner ring block 253 and the outer ring sleeve 252, to lubricate them and prevent corrosion.

[0028] like Figure 5 and Figure 7 As shown, specifically, two corresponding support columns 112 have a first mounting cavity 115 on one side of each other. One end of the limiting column 231 extends into the interior of the first mounting cavity 115. A threaded hole is provided on the bottom side of the limiting column 231. A rotating screw 261 is threaded into the threaded hole on the bottom side of the limiting column 231. The rotating screw 261 has a "T" shaped cross section. A detachable second connecting block 262 is provided between the limiting column 231 and the rotating screw 261. A connecting rod 232 is fixedly installed between two corresponding second connecting blocks 262. A circular through hole is provided in the middle position of the connecting rod 232 corresponding to the position of the threaded column 222. The threaded column 222 passes through the circular through hole of the connecting rod 232 downwards. A locking nut 233 is threadedly connected to the outside of the threaded column 222 corresponding to the top of the connecting rod 232.

[0029] More specifically, rotating the locking nut 233 compresses the connecting rod 232, causing the connecting rod 232 to pull the second connecting block 262 downwards. The second connecting block 262 pulls the limiting post 231 downwards, thus locking the limiting post 231. Furthermore, the locking nut 233 compresses the connecting rod 232 to further lock the threaded post 222, thus performing a fastening operation.

[0030] like Figure 4 , Figure 5 , Figure 8 , Figure 9 and Figure 10As shown, specifically, the snow removal structure includes a sliding block 411 slidably mounted above the connecting plate 314; a guide cavity 215 is provided on the upper side of the mounting box 211; a guide block 413 is fixedly mounted on the bottom side of the sliding block 411; one end of the guide block 413 away from the sliding block 411 passes through the guide cavity 215 and is fixedly mounted on the side of the sliding oil storage box 241; a connecting pipe 511 is fixedly mounted on the upper end of the roof beam frame 313; rotating pipes 512 are equidistantly arranged on the side of the connecting pipe 511; several spray holes 513 are provided on the side of the rotating pipes 512; a sliding snowplow 514 is provided above the roof beam frame 313; several tapping brushes 515 are slidably arranged on the rotating pipes 512 corresponding to the side of the snowplow 514; a third mounting cavity 531 is provided on the upper side of the roof beam frame 313; a rotary motor 53 is provided on the side of the third mounting cavity 531. 2. A movable block 534 is slidably installed inside the third mounting cavity 531. A groove 535 is fixedly installed on the bottom side of the snowplow 514. A threaded rod 533 is fixedly installed at the output end of the rotary motor 532. The threaded rod 533 is threadedly connected to the movable block 534. A groove 535 is provided on the side of the movable block 534. A blocking block 536 that penetrates the groove 535 is fixedly installed inside the third mounting cavity 531. A guide plate 521 is fixedly installed on the side of the roof beam frame 313. A second guide groove 522 is provided on the side of the guide plate 521. A guide rod 523 that penetrates the guide cavity 215 and the second guide groove 522 is fixedly installed on the upper side of the sliding block 411. A rack 524 is fixedly installed on the side of the guide rod 523. A gear sleeve 525 that meshes with the rack 524 is fixedly installed on the side of the rotating tube 512 at the position corresponding to the rack 524.

[0031] More specifically, when the sliding oil reservoir 241 reciprocates, it drives the guide block 413 to move. The guide block 413 then drives the sliding block 411 to move. When snow accumulates only a thin layer on the solar cell structure 315, the reciprocating motion of the sliding block 411 drives the rack 524 to reciprocate. The rack 524 meshes with the gear sleeve 525. Gas is injected into the rotating tube 512 through the connecting pipe 511. The reciprocating motion of the rack 524 drives the gear sleeve 525 and the rotating tube 512 to rotate. The rotating tube 512 drives the injection hole 513 to rotate. Gas then passes through the rotating tube 51... 2. Airflow is used to blow air onto the solar cell structure 315 to remove loose snow from it. When snow accumulates on the solar cell structure 315, the snowplow 514 is moved to push the snow off the solar cell structure 315. When ice forms on the solar cell structure 315, the solar cell structure 315 is slowly moved downward while the rotating tube 512 is rotated. The rotating tube 512 drives the striking brush 515 to rotate. The striking brush 515 moves downward with the snowplow 514, and the rotating striking brush 515 continuously impacts the ice surface to break up the ice.

[0032] like Figure 4 , Figure 5 and Figure 6 As shown, specifically, a first guide groove 213 is provided on the upper side of the first connecting block 221, the first connecting block 221 passes through the interior of the first guide groove 213, a second mounting cavity 251 is provided on the bottom side of the first connecting block 221, a fixed outer ring sleeve 252 is provided inside the second mounting cavity 251, an inner ring block 253 is movably installed inside the outer ring sleeve 252, and a threaded post 222 is fixedly installed below the inner ring block 253.

[0033] More specifically, when the threaded column 222 is rotated, it moves downward while rotating inside the locking threaded hole 214. The threaded column 222 drives the inner ring block 253 downward, the inner ring block 253 drives the outer ring sleeve 252 downward, the outer ring sleeve 252 carries the first connecting block 221 downward, and the first connecting block 221 carries the connecting plate 314 downward.

[0034] Working principle: First, a crane transports the mounting frame 111, with the support columns 112 already fixed, to the designated position. Mounting plates 113 are then laid at equal intervals on the U-shaped mounting frame inside the mounting frame 111, quickly forming a complete floor. Next, two rectangular mounting boxes 211 with open bottom ends are respectively fitted onto the tops of the corresponding support columns 112. Then, the mounting blocks 311, with the beam frame 313 and solar cell structure 315 already fixedly connected, are hoisted as a whole, so that the four L-shaped mounting blocks 311 are respectively positioned above the two mounting boxes 211. At this point, the L-shaped structure of the mounting blocks 311 achieves initial lateral positioning with the mounting boxes 211. Finally, T-shaped limiting posts 231 are inserted into the mounting blocks 31 from top to bottom. In the "T"-shaped third guide hole 312 of 1, the second guide hole 212 of the mounting box 211, and the first guide hole 114 of the support column 112, this step completes the precise centering and initial vertical positioning of all vertically stacked components, preventing them from moving horizontally. The threaded column 222 is pressed down and rotated, causing it to rotate and move downward within the locking threaded hole 214 of the fixing rod 246. The threaded column 222 drives the inner ring block 253 at its top downward. The inner ring block 253 moves within the outer ring sleeve 252 and pushes it downward, thereby driving the first connecting block 221 and the connecting plate 314 fixed thereto to move downward as a whole. The connecting plate 314 presses the mounting block 311 downward, and the mounting block 311 then transmits the force to the mounting box 2. The threaded column 222 and support column 112 form a downward clamping force. Simultaneously, as the threaded column 222 moves downward, the locking nut 233 on it is tightened. The locking nut 233 presses downward against the connecting rod 232. The connecting rod 232, through the compression structure composed of the second connecting blocks 262 at both ends and the rotating screw 261, powerfully pulls all the "T"-shaped limiting columns 231 downward synchronously. This action generates a huge static friction force between the limiting columns 231 and the walls of each guide hole, further pressing the contact surfaces of each component, forming a strong and evenly distributed vertical locking force. This tightly presses all modular components into a high-rigidity whole, achieving the final stability of the mobile house. When cleaning or routine maintenance is required, the electric slide is activated to drive the sliding mechanism. The oil reservoir 241 moves along the fixed rod 246. The movement of the sliding oil reservoir 241 is transmitted to the sliding block 411 through the guide block 413 fixed on its side. The guide block 413 slides in the guide cavity 215 on the upper side of the mounting box 211 to ensure smooth movement. During the movement of the sliding oil reservoir 241, when the pressure sensor 244 on its side contacts the "L"-shaped fixed block 245 fixed on the fixed rod 246, the sensor is triggered. This signal controls the injector 242 to start, accurately and evenly spraying the lubricating oil in the sliding oil reservoir 241 through the two injection pipes 243 to the two most critical parts: the threaded connection between the threaded post 222 and the locking threaded hole 214, and the movable connection between the inner ring block 253 and the outer ring sleeve 252.This directional automatic lubrication forms an oil film on the metal surface, effectively preventing corrosion and ensuring that all fasteners can be easily unscrewed when relocation or disassembly is required. This greatly reduces the difficulty and cost of long-term maintenance. When snow accumulates only a thin layer on the solar cell structure 315, the reciprocating motion of the sliding block 411 drives the rack 524 to reciprocate. The rack 524 meshes with the gear sleeve 525. Gas is injected into the interior of the rotating tube 512 through the connecting pipe 511. The reciprocating motion of the rack 524 drives the gear sleeve 525 and the rotating tube 512 to rotate. The rotating tube 512 drives the injection hole 513 to rotate. The rotating tube 512 blows air onto the solar cell structure 315, removing loose snow from it. When snow accumulates on the solar cell structure 315, the snowplow 514 is moved to push the snow off. When ice forms on the solar cell structure 315, it is slowly moved downwards while the rotating tube 512 is rotated. The rotating tube 512 drives the striking brush 515 to rotate, and the striking brush 515 moves downwards along with the snowplow 514. The rotating striking brush 515 continuously impacts the ice surface to break up the ice.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
