Description

Technical Field

[0001] This invention relates to the field of swimming pool maintenance and energy-saving equipment technology, specifically to an automatic swimming pool heat preservation and humidity control device based on solar energy. Background Technology

[0002] Swimming pools typically need to be covered with an insulating membrane when not in use to reduce water heat loss and prevent dust from falling in. Currently, the operation of taking down and putting up the swimming pool insulating membrane mainly relies on manual operation or simple electric membrane rolling equipment.

[0003] In practical applications, manual roll-up and unrolling are labor-intensive and inefficient, especially when the insulation film absorbs moisture, increasing its weight and requiring operators to expend considerable physical strength to complete the roll-up. Although some venues have introduced electric film rolling machines, most existing equipment still relies on wired mains power. This power supply method requires laying long power cables around the pool, which not only limits the equipment's mobility and flexibility but also poses safety hazards such as electrical leakage, short circuits, and tripping hazards for pedestrians in the damp, watery environment around the pool.

[0004] Furthermore, existing electric membrane winding devices typically only automate the membrane winding process. During the membrane covering operation, due to the softness of the insulation membrane, it cannot be pushed to the water surface by rotating the winding rod. It still requires manual pulling and traction to the other side of the pool, failing to achieve full automation and resulting in a poor user experience. At the same time, traditional membrane winding rods mostly adopt a fixed length structure, which cannot be adjusted according to the width of different lanes or pools, resulting in poor equipment versatility. Moreover, the fixed long rod structure occupies a lot of space during transportation and daily storage. Existing equipment also lacks the use of clean energy, which increases the operating costs of venues in the long run. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic pool heating and humidification device based on solar energy, which solves the problems of high labor intensity and low efficiency caused by the lack of bidirectional power in the traditional pool insulation film deployment and retraction operations.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: an automatic heat preservation and humidity control device for swimming pools based on solar energy, comprising: heat preservation film, pusher, film rolling rod, power distribution cabinet, universal wheel trolley and photovoltaic panel; The film-rolling rod is mounted on the omnidirectional trolley, the insulation film is wound around the film-rolling rod, the pusher is located on the upper part of the insulation film for pulling the insulation film, the power distribution cabinet is mounted on the omnidirectional trolley for driving the film-rolling rod to rotate, and the photovoltaic panel is electrically connected to the power distribution cabinet.

[0007] The pusher is used to pull the insulation film, and the power distribution cabinet is set on the universal wheel to drive the film rolling rod to rotate. The universal wheel facilitates the movement of the device.

[0008] Preferably, the actuator consists of a guide, a lithium battery body, a fixed base, and a propeller.

[0009] The lithium battery body provides independent power, ensuring that the thruster can operate wirelessly and over long distances without being restricted by power cords. The guide is responsible for signal reception and logic control, the propeller is responsible for converting electrical energy into hydrodynamic power, and the fixed base is responsible for transmitting power to the insulation film and maintaining structural stability.

[0010] Preferably, the fixed base is disposed below the insulation film, and the guide is used to receive remote control signals to control the propeller to pull the insulation film.

[0011] The fixed base is close to the bottom of the insulation film, which steadily transmits the thrust generated by the propeller to the front end of the insulation film, pulling the entire insulation film to slide forward on the water surface against the surface tension and resistance of the water, thereby achieving automatic deployment.

[0012] Preferably, the film winding rod consists of a telescopic rod and a gear, with the gear located at the end of the telescopic rod.

[0013] Its function is to provide a flat and firm substrate for the thermal insulation film. When the device is working, the telescopic rod rotates and rolls a large area of ​​flexible thermal insulation film flatly around its cylindrical surface, preventing the film from knotting, wrinkling or piling up, ensuring that it is neatly stored and easy to unfold for the next use.

[0014] Preferably, the telescopic rod adopts a two-layer telescopic design to adapt to swimming pools of different sizes.

[0015] For venues with pools of various sizes, there is no need to customize membrane roll rods for each pool, which improves the versatility of the equipment.

[0016] Preferably, the omnidirectional wheel vehicle consists of a support rod, a fixed rod, and a movable base frame, wherein the movable base frame consists of four omnidirectional wheels.

[0017] The mobile base, combined with four casters, allows the device to rotate freely 360 degrees. This makes it easy to push the device on narrow pool decks, allowing it to be flexibly moved from one lane to another, or pushed into a corner for storage when not in use. This directly solves the problems of traditional fixed devices taking up a lot of space and being unable to move.

[0018] Preferably, the support rod uses a snap-on design to fix the film roll rod, and the power distribution cabinet is fixed to the side of the support rod by welding; the fixing rod is used to maintain the stability of the omnidirectional wheel structure.

[0019] The support rod uses a snap-on design to secure the film reel, providing a quick release function. When it is necessary to replace the film reel with a different length to fit different lane widths, or when the film reel needs to be disassembled and stored separately during the off-season, operators do not need to use complex tools such as screwdrivers and wrenches; they can simply open the snap-on to complete the disassembly and assembly, improving the flexibility and ease of maintenance of the device. The power distribution cabinet is fixed to the side of the support rod by welding, providing the strongest level of rigidity. Since the device needs to be pushed on the ground and the motor will vibrate when it is running, welding ensures that the power distribution cabinet will not loosen or fall off due to vibration or movement.

[0020] Preferably, the power distribution cabinet consists of a motor, a frequency converter, and an energy storage battery.

[0021] The environment around swimming pools is characterized by high humidity, risk of water splashing, and corrosive chlorine. Installing the motor, frequency converter, and energy storage battery in the distribution cabinet can provide waterproofing, dustproofing, and corrosion protection, preventing electrical components from short-circuiting due to moisture or water ingress, and improving the safety and service life of the device in harsh environments.

[0022] Preferably, the motor is connected to a gear located at the end of the film winding rod via a gear rotor connector to drive the film winding rod to complete the automatic film winding function, and the frequency converter is used to adjust the speed of automatic film winding.

[0023] Through the mechanical transmission structure of motor and gear, electrical energy is converted into mechanical energy, generating sufficient torque to overcome the huge resistance and self-weight of the wet insulation film on the water surface, thus realizing the complete automation of the film collection process.

[0024] Preferably, the photovoltaic panel is connected to the energy storage battery, and the energy storage battery stores the green electricity generated by the photovoltaic panel.

[0025] By generating its own electricity through photovoltaic panels and storing it in batteries, the device is cut off from the external power grid. This means that when the device is moved and used by the poolside, there is no need to drag the power cable, eliminating the safety hazard of electric shock caused by wiring near water, and improving the flexibility and freedom of movement of the omnidirectional wheel.

[0026] This invention provides an automatic solar-powered swimming pool heating and humidity control device. It offers the following advantages: 1. This invention adopts integrated wireless remote control operation. Through the guide traction of the pusher and the automatic drive of the motor, it realizes one-click fully automatic covering and recycling of the pool insulation film. It changes the traditional manual pulling operation mode, which not only eliminates heavy manual labor and significantly reduces labor intensity, but also greatly shortens the time of a single film covering or recycling operation. It is especially suitable for large swimming venues, training centers and other scenarios with multiple lanes that need to cover and recycle film daily or frequently. It can quickly respond to usage needs and complete the operation.

[0027] 2. This invention optimizes the design of the membrane roll rod by adopting a two-layer telescopic structure, which allows the length to be freely adjusted according to the width of different swimming pools. This solves the problem of traditional membrane roll rods requiring customization and having poor versatility, and reduces equipment investment costs. At the same time, the end of the membrane roll rod adopts a gear linkage design, making disassembly, maintenance and replacement more convenient.

[0028] 3. This invention utilizes photovoltaic panels to convert solar energy into electrical energy and store it in energy storage batteries to power the entire automated device. This not only enables the device to operate off-grid and solves the problem of difficult wiring around the swimming pool, but also ensures that green electricity is used throughout the process, meeting the environmental protection requirements of energy conservation, emission reduction and zero carbon recycling.

[0031] 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, and 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.

[0032] Example: Please see the appendix Figure 1 -Appendix Figure 5 This invention provides an automatic heat preservation and humidity control device for swimming pools based on solar energy, comprising: a heat preservation film 1, a pusher 2, a film rolling rod 3, a power distribution cabinet 4, a universal wheel 5, and a photovoltaic panel 6; The film-rolling rod 3 is mounted on the omnidirectional wheel 5. The insulation film 1 is wound around the film-rolling rod 3. The pusher 2 is located on the upper part of the insulation film 1 for pulling the insulation film 1. The power distribution cabinet 4 is mounted on the omnidirectional wheel 5 for driving the film-rolling rod 3 to rotate. The photovoltaic panel 6 is electrically connected to the power distribution cabinet 4. The power distribution cabinet 4 consists of a motor 13, a frequency converter 14, and an energy storage battery 15. The photovoltaic panel 6 is connected to the energy storage battery 15, which stores the green electricity generated by the photovoltaic panel 6. The motor 13 is connected to the gear 12 located at the end of the film-rolling rod 3 through a gear 12 rotor connector to drive the film-rolling rod 3 to complete the automatic film winding function. The frequency converter 14 is used to adjust the speed of automatic film winding. The pusher 2 consists of a guide 7 and a lithium battery. The pool body 8, fixed base 9, and propeller 10 are composed of a fixed base 9 located below the insulation film 1. The guide 7 is used to receive remote control signals to control the propeller 10 to pull the insulation film 1. The film winding rod 3 is composed of a telescopic rod 11 and a gear 12. The gear 12 is located at the end of the telescopic rod 11. The telescopic rod 11 adopts a two-layer telescopic design to adapt to pools of different sizes. The omnidirectional wheel trolley 5 is composed of a support rod 16, a fixed rod 17, and a movable base frame 18. The movable base frame 18 is composed of four omnidirectional wheels. The support rod 16 adopts a snap-fit ​​design to fix the film winding rod 3. The power distribution cabinet 4 is fixed to the side of the support rod 16 by welding. The fixed rod 17 is used to maintain the stability of the omnidirectional wheel trolley 5 structure.

[0033] As the physical carrier of the entire device, the omnidirectional wheel trolley 5 provides the necessary structural support and mobility. The omnidirectional wheel trolley 5 is mainly assembled from a mobile base frame 18, support rods 16, and fixed rods 17. The mobile base frame 18 is the load-bearing foundation of the entire device and has a frame structure. To adapt to the high humidity, abundant water, and corrosive substances surrounding the swimming pool, the mobile base frame 18 is typically made of corrosion-resistant stainless steel or high-strength aluminum alloy. Omnidirectional wheels are installed at the four corners of the bottom of the mobile base frame 18. These four omnidirectional wheels form the mobile walking mechanism, enabling the device to move in all directions. Compared to traditional unidirectional wheels or fixed supports, the omnidirectional movement design allows operators to easily push the device to any position within the swimming pool. Beside the swimming lanes, or on the narrow pool deck, the device can be turned and fine-tuned in place. Once the device is moved to the designated working position, the operator locks the casters to ensure the device remains stationary during the film retraction and extension process, preventing accidental displacement due to force. A support rod 16 extends vertically upwards from the mobile base 18. The main function of the support rod 16 is to support the film reel 3, keeping it at an appropriate height above the pool surface. This ensures that the insulation film 1 will not rub against the ground and break due to excessive sag during retraction, while also facilitating daily inspection and maintenance by the operator. The top of the support rod 16 has a special snap-fit ​​structure designed to secure the bearings or shaft ends of the film reel 3. The snap-fit ​​connection, rather than traditional bolt fastening, aims to ensure... The quick assembly and disassembly of the film winding rod 3 allows for easy replacement, repair, or storage during the off-season to save space. Operators can disassemble the rod without wrenches or other complex tools, simply by unfastening the clips, greatly improving equipment maintenance convenience. To enhance the rigidity and stability of the overall structure, a fixing rod 17 is provided between the support rod 16 and the movable base frame 18. The fixing rod 17 acts as a crossbeam or diagonal brace, forming a stable triangular or rectangular frame structure together with the vertical support rod 16 and the horizontal base frame. When the device is under load, especially when the film winding rod 3 is wound with a heavy, moisture-soaked insulation film 1, the fixing rod 17 effectively disperses stress, preventing the support rod 1 from buckling. 6. The device is designed to prevent bending deformation or tilting due to center of gravity shift, ensuring structural safety during dynamic operation. The telescopic rod 11 consists of an inner tube and an outer tube, with length adjustment achieved through a sliding fit. This two-layer telescopic design directly solves the problem of existing fixed-length roll film rods 3 being unable to adapt to pools of different widths. For standard lanes, wide pools, and even irregularly shaped wading pools, operators only need to pull or retract the telescopic rod 11 to adjust it to the optimal length covering the pool width, and then fix it using the locking mechanism. Furthermore, in logistics and warehousing, the retracted telescopic rod 11 significantly reduces packaging volume, lowering the cost and risk of damage during long-item transportation. A gear 12 is installed at the end of the telescopic rod 11.The gear 12 is crucial for mechanical power transmission. Gear 12 transmission offers advantages such as accurate transmission ratio, high torque transmission, and reliable operation. It overcomes the significant static friction and gravity of the wet insulation film 1 during the initial winding. The winding power of the device comes from the distribution cabinet 4, which is securely mounted on the side of the support rod 16 of the omnidirectional wheel trolley 5. To cope with the vibrations during motor 13 operation and the bumps during movement, the distribution cabinet 4 is welded to the support rod 16. Welding provides the highest level of connection strength and rigidity, ensuring that the precision electrical components inside the cabinet will not be damaged due to loose connections. It also ensures the absolute fixation of the cabinet's position, thus maintaining precise alignment between the output shaft of the motor 13 and the gear 12 of the film winding rod 3. The distribution cabinet 4 integrates the motor 13... 3. The inverter 14 and energy storage battery 15, and the motor 13 are connected to the gear 12 at the end of the film winding rod 3 via the gear 12 rotor connector. When the motor 13 is powered on and rotates, it transmits the rotational torque to the gear 12 through the gear 12 rotor connector, thereby driving the entire telescopic rod 11 to rotate and winding the insulation film 1 floating on the water surface layer by layer onto the rod. The inverter 14 is the core of the motor 13 control. During the automatic film winding process, as the insulation film 1 is continuously wound in, the diameter of the film roll on the film winding rod 3 will gradually increase. If the motor 13 maintains a constant speed, the linear velocity of the film roll surface will become faster and faster. This will not only increase the water resistance, causing a surge in the load on the motor 13, but may also tear the insulation film 1 or damage the mechanical structure due to excessive tension. The inverter 14 plays a crucial role in this process. The inverter 14 is used to adjust the power supply frequency and voltage of motor 13 in real time, thereby controlling the speed and torque of motor 13. Through preset control logic, the inverter 14 can achieve soft start, that is, slow acceleration at the moment of start-up to avoid sudden pulling impact. At the same time, during the film take-up process, the speed is adjusted according to load changes or preset curves to maintain a relatively constant take-up linear speed, ensuring a smooth and stable take-up process. The energy storage battery 15 is installed at the bottom of the distribution cabinet 4. It is responsible for providing a stable DC power supply to motor 13, inverter 14 and control circuit. The presence of energy storage battery 15 allows the device to get rid of dependence on mains sockets and eliminates the safety hazards caused by dragging cables. In order to achieve energy self-sufficiency and green environmental protection, the device is equipped with photovoltaic panels 6. The photovoltaic panels 6 are installed on the device. The photovoltaic panel 6 is positioned to receive sunlight and is electrically connected to the energy storage battery 15 inside the power distribution cabinet 4 via cables. During the day, the photovoltaic panel 6 converts the received solar radiation energy into electrical energy. After being regulated by the charging controller, this electrical energy is stored in the energy storage battery 15. This design enables the device to operate off-grid. Whether in an outdoor open-air swimming pool or a well-lit indoor swimming pool, the device can utilize ambient light for power replenishment, reducing the frequency of manual charging and the venue's power operation costs. For equipment that is idle for a long time, solar power replenishment can also prevent the battery from being damaged by over-discharge, extending the service life of the equipment. The pusher 2 mainly consists of a guide 7, a lithium battery body 8, a fixed base 9, and a propeller 10. The fixed base 9 adopts a hydrodynamic optimization design.It is positioned below the front end of the insulation membrane 1. First, the propeller 10 is completely submerged in water, obtaining a continuous and stable water reaction force. Second, the insulation membrane 1 covering it acts as a float, providing necessary buoyancy support. Finally, the base located under the membrane effectively prevents the propeller 10 from accidentally damaging floating objects on the water surface, acting as a protective shield. The fixed base 9 is tightly connected to the edge of the insulation membrane 1, converting the thrust generated by the pusher 2 into a pulling force on the membrane. The lithium battery body 8 provides independent power to the pusher 2. Since the membrane covering process involves pulling the membrane to the opposite side of the pool, a considerable distance that cannot be connected by cables, the pusher 2 must have an independent power source. The built-in high-energy-density lithium battery ensures the propulsion... The propeller 2 has sufficient endurance to complete multiple mulching operations. The propeller 10 is the power output component, driven by a DC motor 13 to generate a backward water flow, thus providing forward thrust. The guide 7 is the control center of the propeller 2, integrating a wireless signal receiver. During mulching operations, the operator stands on the shore and sends commands via a handheld remote control. Upon receiving the signal, the guide 7 controls the start, stop, speed, and direction of the propeller 10. This makes the propeller 2 not just a simple power source, but also a controllable device. Operators can adjust the propeller 2's forward direction in real time according to wind direction, water flow, and lane position, ensuring the insulation membrane 1 unfolds straight along the lane centerline, preventing it from veering off course, hitting walls, or becoming entangled in the lane lines.

[0034] When the pool needs to be covered, the operator first pushes the caster 5 to the designated position at one end of the pool and locks the casters. At this time, the membrane roll rod 3 is in a free-rotating state or the motor 13 is disengaged. The operator starts the pusher 2 and issues a forward command via remote control. The pusher 2, located below the front end of the insulation membrane 1, receives the command, and the propeller 10 rotates to generate thrust. This thrust pulls the leading edge of the insulation membrane 1, causing the entire membrane roll to be passively unrolled from the caster 3. The pusher 2 drags the insulation membrane 1 across the water surface, moving towards the opposite bank of the pool. During this process, the operator fine-tunes the direction via remote control, and the guide 7 executes the steering logic to ensure that the covering path is straight. When the pusher 2 reaches the opposite bank, the propeller 10 stops, and the insulation membrane 1 completely covers the water surface, completing the covering operation. When the pool needs to be used, the operator first removes the pusher 2 or puts it in a follow-up state. Then, the operator operates the control panel on the power distribution cabinet 4 or remote control. The controller initiates the film winding process. The energy storage battery 15 supplies power to the frequency converter 14, which in turn controls the motor 13 to start. The motor 13 drives the gear 12 at the end of the film winding rod 3 through the rotor connector of the gear 12, causing the telescopic rod 11 to start rotating. The rotating telescopic rod 11 generates torque, pulling the insulation film 1 on the water surface back and winding it onto the rod. In the initial stage of film winding, due to the long length of the pulled film and the high water resistance, the frequency converter 14 controls the motor 13 to output a large low-speed torque to achieve a smooth start. As film winding progresses, the roll diameter increases, and the frequency converter 14 automatically adjusts the speed to maintain a stable linear speed during the winding process. At the same time, the squeezing action during the winding process will squeeze most of the water on the film surface back into the pool. When the insulation film 1 is completely wound onto the rod, the motor 13 stops, and the film winding operation is completed. At this time, the device can be pushed away from the poolside by the universal wheel 5 and stored in a designated area. During this period, the photovoltaic panel 6 continuously replenishes the battery with power to prepare for the next operation.

[0035] Working principle: The device uses photovoltaic panels 6 to collect solar energy and convert it into electrical energy, which is stored in the energy storage battery 15 in the power distribution cabinet 4 to achieve green power supply. During operation, the device is moved to the edge of the pool by the mobile base frame 18 of the omnidirectional wheel trolley 5, and the length of the telescopic rod 11 of the film winding rod 3 is adjusted to fit the size of the pool. During the heat preservation and moisture retention operation, the pusher 2 located at the front end of the heat preservation film 1 is controlled by remote control. The guide 7 receives the signal and controls the lithium battery body 8 to drive the propeller 10 to rotate. The fixed base 9 pulls the heat preservation film 1 to automatically cover the water surface. During the film retraction operation, the energy storage battery 15 supplies power to the motor 13. After the speed is adjusted by the frequency converter 14, the motor 13 drives the gear 12 at the end of the film winding rod 3 to rotate, automatically winding and retracting the heat preservation film 1, thus completing the fully automatic covering and retraction operation.
