Description

Technical Field

[0001] This application relates to the field of container house technology, and in particular to a multifunctional expandable container house. Background Technology

[0002] Container houses are widely used in temporary offices, field construction, and emergency shelters due to their modularity, ease of transportation, and rapid installation. To increase usable space, various expandable container houses have emerged in existing technologies, using sliding or flipping mechanisms to expand the internal space.

[0003] Patent CN223240834U discloses an expandable box-type house, including components such as a roof, a box body, an expandable top plate, and an expandable bottom plate. This patent achieves the house's spatial expansion function through mechanisms such as expansion top plate sliding grooves, flipping grooves, and rotating blocks, effectively solving the problem of fixed space in traditional box-type houses. However, its function is relatively simple, mainly focusing on spatial expansion. Although some solutions propose adding solar panels or rainwater harvesting devices, these functional modules are usually installed independently in fixed parts of the box body, lacking effective connection with the house's expansion. This leads to the following problems: First, activating the functional system requires additional operation, resulting in low intelligence; second, solar panels may be blocked by the box body's own structure, affecting power generation efficiency; third, the rainwater harvesting area is limited and cannot increase with roof expansion; fourth, the expansion area lacks targeted functional configurations. Utility Model Content

[0004] Therefore, it is necessary to provide a multifunctional expandable container house to overcome the shortcomings mentioned in the background art.

[0005] A multifunctional expandable box-type house includes a box body, a roof, an expandable top plate slidably installed within the roof, and an expandable bottom plate rotatably installed on the box body. A solar panel is fixedly installed on the upper surface of the expandable top plate, and a water collection trough is fixedly installed at the front edge of the expandable top plate. A water tank and a control box are installed inside the box body. The water collection trough is connected to the water tank through a pipe. A limit switch is installed on the roof. When the expandable top plate slides to the fully expanded position, the limit switch is triggered. The limit switch is electrically connected to the control box. After receiving the trigger signal from the limit switch, the control box connects the output circuit of the solar panel.

[0006] As a preferred embodiment of the multifunctional expandable container house of this utility model, a water pump is installed on the pipeline, the water pump is electrically connected to the control box, and when the limit switch is triggered, the control box controls the water pump to start.

[0007] As a preferred embodiment of the multifunctional expandable container house of this utility model, a liquid level sensor is installed in the water collection tank. The liquid level sensor is electrically connected to the control box. The control box is configured to start the water pump when it simultaneously receives a trigger signal from a limit switch and the liquid level sensor detects a valid water level.

[0008] As a preferred embodiment of the multifunctional expandable box house of this utility model, a waterproof surface layer is laid on the unfolded surface of the expandable base plate.

[0009] As a preferred embodiment of the multifunctional expandable container house of this utility model, when the expandable base plate is in the fully expanded position, a position sensor switch is provided on the supporting structure below it. The position sensor switch is electrically connected to the control box and is used to turn on the lighting device installed in the expandable area.

[0010] As a preferred embodiment of the multifunctional expandable box house of this utility model, the solar panel is a flexible solar panel, which is fixed to the upper surface of the expandable top plate by adhesive or mechanical fastener.

[0021] According to one aspect of this application, embodiments of this application provide a multifunctional expandable container house; see [link to relevant documentation]. Figure 1 The multifunctional expandable container house includes a container body 1, a roof 2, an expandable top plate 3, and an expandable bottom plate 4. A solar panel 6 is fixedly installed on the upper surface of the expandable top plate 3, and a water collection tank 5 is fixedly installed at the front edge of the expandable top plate 3. A water tank 7 and a control box 8 are installed inside the container body 1. The water collection tank 5 is connected to the water tank 7 through a pipe. A limit switch 9 is installed on the roof 2. When the expandable top plate 3 slides to the fully expanded position, the limit switch 9 is triggered. The limit switch 9 is electrically connected to the control box 8. After receiving the trigger signal from the limit switch 9, the control box 8 connects the output circuit of the solar panel 6.

[0022] When the container house of this utility model is in the transport or storage state, the extendable top panel 3 is retracted inside the cover 2, and the extendable bottom panel 4 is flipped up and retracted tightly against the side wall of the container 1. When needed, the extendable top panel 3 is slid outward from the cover 2 by manual or mechanical means, while the extendable bottom panel 4 is flipped down and laid flat to form an extended living space.

[0023] After the extended roof panel 3 is fully extended, its upper surface becomes an ideal rain-collecting surface. To achieve energy self-sufficiency, a flexible solar panel 6 is laid on the upper surface of the extended roof panel 3 by means of waterproof adhesive or clips. The flexible solar panel 6 is lightweight and has good toughness, and does not affect the sliding and storage of the extended roof panel 3.

[0024] A water collection trough 5 is bolted to the front edge of the extended top plate 3 at its farthest point. The water collection trough 5 is preferably made of U-shaped aluminum alloy profile, and its length matches the width of the front edge of the extended top plate 3.

[0025] A water tank 7 and a control box 8 are fixedly installed inside the housing 1. The drain outlet of the water collection tank 5 is connected to the inlet of the water pump through a flexible pipe, and the outlet of the water pump is connected to the water tank 7 through a pipe. The water pump is preferably a DC low-pressure water pump, which can be directly or indirectly driven by the solar panel 6.

[0026] Limit switch 9 is installed at the end of the slide rail inside the top cover 2. Its position is precisely calibrated to ensure that it will only be pressed or triggered when the extension top plate 3 slides to its fully extended limit position. Limit switch 9 is connected to control box 8 via wires. When the extension top plate 3 is pushed to the fully extended position, the limit switch 9 is triggered. Limit switch 9 sends a trigger signal to control box 8, which then performs the following operations: When the output circuit of solar panel 6 is turned on, the system begins to generate electricity using solar energy to power its own electrical equipment and stores excess energy in the battery.

[0027] Based on the preset logic, prepare or directly start the water pump.

[0028] To avoid collecting initial dust-laden rainwater or the pump running dry, the pump has the following two control modes: Mode 1: The control box 8 integrates a time-delay relay. Upon receiving a signal from the limit switch 9, the time-delay relay starts timing, and the water pump starts approximately 8 minutes later. This waiting period allows initial contaminants adhering to the roof to be washed away by rainwater, improving the quality of the collected water. Mode 2: A level sensor is installed in the water collection tank 5. The control box 8 is programmed with an AND logic control: that is, the water pump 154 ​​will only start immediately when two conditions are met simultaneously—the "deployed" signal from the limit switch 9 and the "water present" signal from the level sensor. This mode is energy-saving and can fundamentally prevent the water pump from running dry, extending the equipment's lifespan.

[0029] In one embodiment, a position sensor switch is installed on the support leg or foundation below the extension base 4. This switch is triggered when the extension base 4 is flipped to a fully horizontal use position. The position sensor switch is also connected to the control box 8, which automatically illuminates the lighting fixtures installed in the extension area for user convenience.

[0030] Once the user unfolds the house, the system enters standby mode. In case of rainfall, rainwater flows along the sloping surface of the extended roof panel 3 into the collection tank 5. At this time, the limit switch 9 is activated, and the system power is on. The water pump automatically starts according to the selected mode, transporting the collected rainwater to the water tank 7 for storage, which can be used for non-potable purposes such as flushing. Throughout the process, energy is primarily provided by the solar panels 6, achieving intelligent and integrated energy and water resource collection.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
