Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of construction methods, and specifically relates to a pool wall installation scaffold-free construction system. BACKGROUND

[0002] In modern architecture and water conservancy engineering, water pools are widely used in various places such as swimming pools, water storage pools, sewage treatment pools, etc. as an important infrastructure. The construction of water pools involves multiple links, including foundation excavation, steel bar binding, formwork installation, concrete pouring, waterproof treatment, etc. Especially in the construction process of the pool wall and pool bottom, a large amount of high-altitude work is involved, which puts forward higher requirements for the construction method. A water pool refers to a structure used for storing water or other liquids, widely used in the fields of architecture, water conservancy, municipal administration, etc. It can be indoor or outdoor, used for various purposes such as swimming pools, water storage pools, landscape pools, sewage treatment pools, etc. The pool wall refers to the side wall part of the water pool, used to enclose and support the water or other liquids in the water pool. Scaffold-free refers to a construction method that does not need to use traditional scaffolding during construction. This method replaces the role of scaffolding through other equipment or technical means to improve construction efficiency and safety.

[0003] In the traditional construction process of water pool wall installation, the following problems are usually encountered: the internal space of the water pool is relatively closed, especially in large water pools, the narrow internal space brings great inconvenience to construction. The traditional construction method needs to set up a large number of scaffolds inside the water pool to provide working platforms and passages. However, this approach not only occupies a lot of space, but also affects the normal progress of other procedures. The waterproof performance of the water pool is crucial, and any embedded fixing point design must take into account the waterproof requirement. The traditional construction method often needs to embed fixing points inside the water pool for fixing scaffolds or supporting structures. However, this method of embedding fixing points will damage the waterproof layer of the water pool, causing leakage and other problems. The construction of the pool wall usually needs to be carried out in the air, while the space inside the water pool is relatively limited, which greatly increases the difficulty of construction. The traditional scaffolding needs a lot of manpower and time, especially when working in the air, workers need to frequently climb the scaffolding, increasing the difficulty of construction and safety hazards.

[0004] Disadvantages of traditional scaffold-free construction systems for water tank walls: Traditional scaffolding construction methods are inefficient, especially in the construction of large water tanks, where the erection and dismantling of scaffolding consumes a significant amount of time and manpower. Furthermore, the presence of scaffolding forces other processes (such as concrete pouring and waterproofing) to bypass it, further impacting construction efficiency. The use of scaffolding inside the water tank increases safety risks. Workers climbing and working on scaffolding are prone to falls and collisions. In addition, the stability of the scaffolding is a major issue; loosening or collapse poses serious safety hazards to workers. The presence of scaffolding occupies valuable internal space, making the already cramped interior of the water tank even more congested. This not only affects the convenience of construction but may also prevent other processes from proceeding normally, further impacting the overall project schedule. Summary of the Invention

[0005] In view of this, the present invention provides a scaffold-free construction system for installing pool walls, which solves the problem of space constraints caused by the inability to pre-embed fixed points due to waterproofing requirements during pool construction. By adopting a hanging frame ladder cage system, a safe and reliable working passage and operating platform are provided, thereby improving construction efficiency.

[0006] This invention is implemented as follows:

[0007] This invention provides a scaffold-free construction system for installing water tank walls, comprising a hanging ladder cage. The hanging ladder cage includes a vertical ladder, horizontal supports, a working cage, and a fixing device. The vertical ladder comprises multiple splicable ladder segments, which are connected by bolts or welded together. The hanging ladder cage forms a vertical channel, and the vertical ladder is suspended from the top within the vertical channel. The horizontal supports are welded to the side of the vertical ladder near the tank wall and include at least one pair of parallel support rods. One end of each support rod is welded to or bolted to the vertical ladder, and the other end is fixed to the tank wall. The fixing device includes a tie rod safety clamp and a top hanging point, which is fixed to the top structure of the tank by drilling holes and using expansion bolts.

[0008] The vertical passage refers to the vertical space where the hanging ladder cage is located. The vertical ladder is installed in the vertical passage and fixed by suspension from the top to ensure the stability of the vertical ladder.

[0009] The top suspension and horizontal supports ensure the structural stability of the vertical ladder, improving the safety of the entire system. The work cage provides a safe and reliable working environment for workers, reducing operational risks. The horizontal supports enhance the structural stability of the vertical ladder, preventing swaying during use. The top hanging points are secured with expansion bolts, ensuring the structural stability of the vertical ladder. Pull-out safety clamps further secure the vertical ladder, preventing loosening during use.

[0010] Based on the above technical solution, the scaffold-free construction system for installing water tank walls according to the present invention can be further improved as follows:

[0011] The horizontal support is equipped with an adjustment mechanism for adjusting the length of the horizontal support. The adjustment mechanism includes one or more telescopic segments, each of which consists of two tubular components, an outer tube and an inner tube. The outer tube is fitted over the inner tube, and an adjustment bolt is provided between the outer tube and the inner tube. The extension and retraction of the telescopic segment are controlled by rotating the adjustment bolt.

[0012] The advantages of adopting the above-mentioned improved solution are as follows: the adjustable horizontal support can adapt to pool walls of different widths, thus increasing the system's applicability. The length of the horizontal support can be quickly adjusted by adjusting bolts or knobs, simplifying the installation and adjustment process.

[0013] Furthermore, the pull-out safety clamp includes two symmetrical clamping plates connected by a spring. One end of each clamping plate is fixed to both sides of the vertical ladder, and the other end is provided with an outwardly protruding hook-like structure. The hook-like structure grips the edge of the vertical ladder by the tension of the spring.

[0014] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the clamping plates and hook-like structures connected by springs enhance the fixing effect of the pull-out safety clamps. The design of the pull-out safety clamps improves the fixing stability of the vertical ladder.

[0015] Furthermore, the work cage is connected to the vertical ladder via a rope. One end of the rope is fixed to the vertical ladder, and the other end is connected to a buckle on the work cage. The buckle is designed as a quick-release buckle, and a spring locking device is provided below the quick-release buckle. The spring locking device includes a spring and a latch. The spring is located below the latch, and the latch is secured by the pressure of the spring. A manual locking button is provided on the quick-release buckle, located on one side of the quick-release buckle. The buckle is locked manually. The front end of the latch is designed at an angle to facilitate insertion into the slot of the vertical ladder; the rear end of the latch is designed at a right angle or with a barb to prevent it from coming off.

[0016] The advantages of adopting the above-mentioned improvement scheme are as follows: the quick-release buckle design makes it easier to adjust the height of the work cage, thus improving work efficiency. The connection between ropes and buckles ensures the stability of the work cage.

[0017] Furthermore, the vertical ladder has multiple fixing points, which are distributed at different heights of the vertical ladder. The fixing points are fixed by welding or bolt connection. One end of the fixing point is connected to the vertical ladder, and the other end is provided with a locking mechanism. The locking mechanism consists of two tubular components, an outer tube sleeved on the outside of the inner tube, and an adjusting bolt or knob is provided between the inner and outer tubes.

[0018] The fixed points are distributed at certain intervals at different heights of the vertical ladder, usually between 1 and 2 meters apart, depending on the actual working height requirements.

[0019] Multiple fixed points can be adjusted to meet different operational needs at varying heights, improving the system's flexibility and adaptability. The fixed points allow the work cage to be quickly adjusted to the required height, facilitating operations at different elevations.

[0020] Furthermore, each of the ladder segments is provided with a reinforcing rib at its bottom, and the reinforcing rib is welded perpendicularly to the ladder segment.

[0021] Furthermore, the work cage is welded from square steel pipes to form a rectangular frame structure. The rectangular frame structure is surrounded by a fence. The work cage has an opening design, which is located on one side of the work cage, and the opening is used for workers to enter and exit.

[0022] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the rectangular frame structure and the fence provide effective safety protection for workers and reduce operational risks. The frame structure formed by welding square steel pipes has high strength and stability.

[0023] Furthermore, the rope is a high-strength nylon rope or a steel wire rope.

[0024] Furthermore, each segment of the vertical ladder is provided with steps, and the steps are provided with anti-slip textures or anti-slip strips.

[0025] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the anti-slip texture or anti-slip strip design increases friction during climbing, reducing the risk of slipping. The anti-slip design improves the safety performance of vertical hanging ladders.

[0026] Furthermore, a visual operation assistance system is installed inside the work cage, including a camera, a display screen, and a controller. The camera is installed on the top of the work cage, and the display screen is located inside the work cage. The camera and the display screen are installed in a single encapsulated housing. The camera and the display screen are connected to the controller via a wired connection. The controller is used to receive the images captured by the camera and display them on the display screen in real time through video transmission technology. At the same time, it processes AR information and overlays guidance information on the video image on the display screen.

[0027] Camera: High-definition webcam, waterproof and dustproof, suitable for outdoor use.

[0028] Model: For example, DS-2CD2T25FWD-I5 is a high-definition webcam that supports 1080p resolution, has wide dynamic range and night vision capabilities, and is suitable for use in various environments.

[0029] Display: High-brightness LCD monitor with touch operation support.

[0030] Model: For example, the ELO 1725L 17-inch touchscreen monitor, which features high brightness and wide viewing angles, making it suitable for use in bright light, and supports multi-touch operation.

[0031] The waterproof housing is made of waterproof materials, such as stainless steel or aluminum alloy, and is equipped with a sealing ring to ensure overall airtightness.

[0032] Controller model: Embedded computing device.

[0033] Model: Raspberry Pi 4 Model B or NVIDIA Jetson Nano development board.

[0034] Raspberry Pi 4 Model B: Supports multiple operating systems (such as Raspbian and Ubuntu), has 4GB of memory and a gigabit Ethernet interface, and is suitable for video processing and data transmission.

[0035] NVIDIA Jetson Nano Development Board: Built-in GPU supports high-performance computing and graphics processing, suitable for complex AR information processing.

[0064] 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.

[0065] like Figure 3 , Figure 4 The image shows a first embodiment of a scaffold-free construction system for installing pool walls provided by the present invention. In this embodiment, the construction preparation is as follows:

[0066] 1. Determine the required length and quantity of the hanging ladder cages according to construction needs. Taking the construction of the sewage treatment station of the high-end agricultural equipment intelligent manufacturing project as an example, the required hanging ladder length is 6 meters and the quantity is 4.

[0067] 2. Procurement of materials such as 40mm carbon steel rectangular tubing and 20mm round steel, based on the length and quantity of the ladder cage, will be delivered to the site.

[0068] 3. Fabricate the hanging frame, ladder cage, and safety accessories;

[0069] 4. Purchase fall arrestors, ropes, expansion bolts, and other necessary materials.

[0070] 5. Personnel preparation:

[0071] (1) The installation of the hanging frame, ladder cage and sewage tank is a high-altitude operation. The operators must pass the physical examination of a hospital of Grade II or above, and have no high blood pressure, heart disease or mental illness that cannot be controlled. The operators must be between 18 and 45 years old and be able to adapt to high-altitude operations.

[0072] (2) Personnel shall be assigned to assist in the installation of each set of ladder cage brackets, and only one person is allowed to work on the same ladder cage bracket at the same time.

[0073] (3) Workers must undergo project safety education and safety technical briefing by a special engineer.

[0074] Fabrication of hanging frame ladder cage:

[0075] 1. Construction of a vertical hanging ladder:

[0076] The vertical ladder of the hanging frame is made entirely of 40mm carbon steel rectangular tubing. Taking the sewage treatment pond in the Frontier Science and Technology City as an example, the vertical ladder is 6 meters long. To reduce the overall weight of the ladder, the ladder step distance is 40 centimeters, and the top of the ladder is supported by 20mm round steel. Horizontally, two horizontal braces, each 30 centimeters long, are installed every 2 meters along the ladder.

[0077] 2. Making the hanging cage:

[0078] The entire ladder cage is made of 40 carbon steel rectangular tubing, with dimensions of 50 cm × 50 cm × 50 cm. The top of the ladder cage is made of 20 round steel hooks, as shown in the figure. The bottom is made of 40 carbon steel rectangular tubing with two horizontal supports.

[0079] 3. Safety accessory fabrication:

[0080] Fall arrestors should be purchased as finished products based on the working height.

[0081] Back-pulling anti-slip hook. Welded from 20mm round steel, dimensions are 25cm wide and 40cm long.

[0082] Installation of hanging frame ladder cage:

[0083] 1. Vertical ladder installation. First, use a hand drill to drill two holes, each at least 3cm deep and 2cm in diameter, above the water tank where the ladder will be installed. These holes will be used for suspending the ladder. Figure 3 As shown. Two installers attached ropes to both sides of the bottom of the ladder, and together with two other workers, lifted the ladder from the top to the hanging position. The four workers then worked together to suspend the ladder in the designated position, as shown. Figure 4 As shown. After the vertical ladder is suspended, immediately pull the anti-slip hook to prevent the ladder from shifting and falling. The back hook is not under any force under normal circumstances, and only plays a supporting role if the ladder slips.

[0084] 2. Cage Installation. Two installers attach large ropes to both sides of the bottom of the ladder, lower the cage to the suspension position above the pool, and then finely adjust the hook position using the large ropes to install the cage onto the ladder.

[0085] 3. Installation of the fall arrestor. The fall arrestor is secured using #12 hook expansion bolts and installed on the top of the pool.

[0086] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The image shows a second embodiment of a scaffold-free construction system for installing a pool wall according to the present invention. In this embodiment, a hanging frame ladder cage is included. The hanging frame ladder cage includes a vertical ladder 10, a horizontal support 20, a working hanging cage 30, and a fixing device 40. The vertical ladder 10 includes multiple splicable ladder segments 11. The ladder segments 11 are connected by bolts or welded together. The hanging frame ladder cage forms a vertical channel. The vertical ladder 10 is suspended from the top in the vertical channel. The horizontal support 20 is welded to the side of the vertical ladder 10 near the pool wall. The horizontal support 20 includes at least a pair of parallel support rods 21. One end of the support rod 21 is welded to the vertical ladder 10 or fixed by bolts, and the other end is fixed to the pool wall. The fixing device 40 includes a pull-out safety clamp 41 and a top hanging point 42. The top hanging point 42 is fixed to the top structure of the pool by drilling holes and using expansion bolts.

[0087] The top mounting points are secured to the pool's roof structure by drilling holes and using expansion bolts. The mounting point is typically a metal plate or ring with holes. Expansion bolts are inserted into pre-drilled holes, and then the nuts are tightened, causing the bolts to expand within the holes and firmly securing the top mounting point to the concrete structure at the top of the pool. The positions of the mounting points need to be measured and marked beforehand to ensure all points are on the same horizontal line, guaranteeing the verticality of the ladder.

[0088] like Figure 6 As shown, in the above technical solution, the horizontal support 20 is provided with an adjustment mechanism 22. The adjustment mechanism 22 is used to adjust the length of the horizontal support 20. The adjustment mechanism 22 includes one or more telescopic segments. Each telescopic segment consists of two tubular components, including an outer tube and an inner tube. The outer tube is sleeved outside the inner tube. An adjustment bolt is provided between the outer tube and the inner tube. The extension and contraction of the telescopic segment are controlled by rotating the adjustment bolt. Specifically, the setting of the adjustment mechanism can refer to a multi-functional RV storage top telescopic bracket (publication number: CN219749972U) with application number CN202320967568.5, wherein: the telescopic bracket is located at the rear end of the U-shaped frame 3, the telescopic bracket includes a crossbeam 6, a second hydraulic cylinder 5, a telescopic rod 8, and a telescopic sleeve 7, the telescopic sleeve 7 is fixed on the rear end of the U-shaped frame 3, one end of the telescopic rod 8 is fixed on the crossbeam 6, and the other end of the telescopic rod is slidably connected to the telescopic sleeve 7, one end of the piston rod in the second hydraulic cylinder 5 is connected to the crossbeam 6, the cylinder body in the second hydraulic cylinder 5 is hinged to the front end of the U-shaped frame 3, and bicycle mounting seats 9 are provided at both ends of the crossbeam 6.

[0089] Furthermore, in the above technical solution, the pull safety clamp 41 includes two symmetrical clamps connected by a spring. One end of the clamp is fixed to both sides of the vertical ladder 10, and the other end is provided with an outwardly protruding hook structure. The hook structure grips the edge of the vertical ladder 10 by the tension of the spring.

[0090] The clamp is also equipped with an adjustment knob, which can be rotated to adjust the tension of the spring to meet different fixing requirements.

[0091] like Figure 9As shown, further in the above technical solution, the work cage 30 is connected to the vertical ladder 10 via a rope. One end of the rope is fixed to the vertical ladder 10, and the other end is connected to a buckle on the work cage 30. The buckle is designed as a quick-release buckle, and a spring locking device is provided below the quick-release buckle. The spring locking device includes a spring and a latch. The spring is located below the latch, and the latch is secured by the pressure of the spring. A manual locking button is provided on the quick-release buckle, located on one side of the quick-release buckle. The buckle is locked manually. The front end of the latch is designed at an angle to facilitate insertion into the slot of the vertical ladder; the rear end of the latch is designed at a right angle or with a barb to prevent it from coming out. The purpose of designing the front end of the latch at an angle is mainly to facilitate insertion into the slot of the vertical ladder, reduce resistance during insertion, and ensure that the latch can smoothly enter the slot. The angle range of the angle should be within a reasonable range to ensure both easy insertion and sufficient stability. Typically, the tilt angle should be between 10° and 30°.

[0092] The manual lock button consists of the following components:

[0093] Button: Used to control the action of the locking mechanism by rotating or pressing.

[0094] The locking mechanism includes a latch locking block, a locking spring, and a rotating shaft.

[0095] Locking block for latch: Located above or to the side of the latch, used to fix the position of the latch.

[0096] Locking spring: Located below or inside the latch locking block, the latch is fixed by the pressure of the spring.

[0097] Rotary shaft: Used to connect buttons and locking mechanisms, transmitting force through rotational motion.

[0098] Transmission mechanisms include connecting rods, gears, or racks:

[0099] Linkage: Connects the button and the latch locking block, transmitting rotational or pressing actions.

[0100] Gears or racks: used to convert rotary motion into linear motion, or to directly transmit linear motion.

[0101] Main locking mechanism: The aforementioned spring lock and manual lock button serve as the main locking mechanism, ensuring a secure connection of the latches.

[0102] Auxiliary locking mechanism: An auxiliary locking mechanism, such as an additional hook or clip, is added to the buckle as a double safety measure. The auxiliary locking mechanism can be a small hook or clip that is fixed to one side of the buckle. After the main locking mechanism locks, the auxiliary locking mechanism further locks the buckle, enhancing stability.

[0103] Rotary locking:

[0104] Rotation operation: When the button is rotated, the rotational force is transmitted to the latch locking block through the linkage or gear mechanism.

[0105] Locking process: When the rotary button is turned clockwise, the locking block moves downward, and the locking spring fixes the latch in the slot of the vertical ladder.

[0106] Unlocking process: When the rotary button is turned counterclockwise, the locking block moves upward, releasing the latch and allowing it to be removed from the slot of the vertical ladder.

[0107] Press to lock:

[0108] Pressing operation: When the button is pressed, the pressing force is transmitted to the latch locking block through the linkage.

[0109] Locking process: When the button is pressed, the locking block moves downward, and the locking spring fixes the latch in the slot of the vertical ladder.

[0110] Unlocking process: When the button is released, the locking block moves upward, releasing the latch, allowing the latch to be removed from the slot of the vertical ladder.

[0111] The quick-release buckle includes a mounting base and a movable locking arm. The mounting base is fixed to one side of the ladder cage, and the movable locking arm is connected to the mounting base via a hinge. The mounting base has an internal groove whose shape matches the locking slot on the vertical ladder. The movable locking arm has a latch that engages with the locking slot on the vertical ladder. The movable locking arm also has a locking handle; rotating the locking handle secures the latch within the locking slot, thus fixing the ladder cage to the vertical ladder. When the height of the ladder cage needs to be adjusted, rotating the locking handle in the opposite direction releases the latch, allowing for easy adjustment of the ladder cage's position.

[0112] like Figure 8 As shown, further, in the above technical solution, the vertical ladder 10 has multiple fixing points, which are distributed at different heights of the vertical ladder 10. The fixing points are fixed by welding or bolt connection. One end of the fixing point is connected to the vertical ladder 10, and the other end is provided with a locking mechanism 211. The locking mechanism 211 consists of two tubular components, an outer tube sleeved on the outside of the inner tube, and an adjusting bolt or knob is provided between the inner and outer tubes.

[0113] The rotating lock is a feature where a rotating locking device is installed at one end of the telescopic rod. The length of the telescopic rod is locked by rotating a knob on the locking device. The locking device includes a threaded knob that is connected to the inner and outer tubes of the telescopic rod via threads. Rotating the knob adjusts the length of the telescopic rod, and tightening the knob locks the length.

[0114] Operation: When the knob is turned to loosen, the length of the telescopic rod can be adjusted; when the knob is turned to tighten, the telescopic rod is locked in the current position.

[0115] Button Locking: A button locking device is provided at one end of the telescopic rod, which locks the length of the telescopic rod by pressing the button. The locking device includes a button and a set of spring locking pins. The button is located on the outer tube of the telescopic rod, and the spring locking pins are located on the inner tube.

[0116] Operation: When the button is pressed, the spring locking pin retracts, allowing adjustment of the telescopic rod's length; when the button is released, the spring locking pin pops out, locking the telescopic rod in its current position.

[0117] The form of the fixed point:

[0118] Hole-type fixing points: Holes of a certain diameter are drilled in the uprights of the vertical ladder. The holes can be circular or elliptical, and their size is determined by the size of the connecting parts (such as pins, bolts, etc.). The edges of the holes are ground to prevent wear on the connecting parts.

[0119] Hook-type fixing point: Metal hooks are welded or bolted to the uprights of the vertical ladder. The hooks can be designed in U-shape or L-shape to facilitate the quick attachment of ropes or other connecting parts.

[0120] Specialized fixing devices: Specialized fixing clamps or clips are designed to be fixed to the ladder uprights by welding or bolting. This type of fixing device can provide a larger contact area and enhance the connection strength.

[0121] Furthermore, in the above technical solution, each ladder segment 11 is provided with a reinforcing rib at its bottom, and the reinforcing rib is welded perpendicularly to the ladder segment 11.

[0122] Furthermore, in the above technical solution, the work cage 30 is welded from square steel pipes to form a rectangular frame structure. The rectangular frame structure is surrounded by a fence. The work cage 30 has an opening design, which is located on one side of the work cage 30 and is used for workers to enter and exit.

[0123] The opening features a door frame upon which a door leaf is mounted. The door leaf is connected to the door frame via hinges and can be opened outwards. The door leaf is equipped with a safety lock, consisting of a lock body and a latch. The lock body is fixed to the door frame, and the latch is attached to the door leaf. When the door is closed, the latch inserts into the lock body, securing the door leaf in the closed position via a locking device (such as a key lock or electromagnetic lock), preventing accidental opening during use. Additionally, the door leaf has a handle for easy opening and closing by workers. For enhanced safety, a sealing strip is installed around the door leaf to prevent moisture from entering the cage. An emergency unlock button is also located on the inside of the door leaf, allowing for quick escape in emergencies.

[0124] Furthermore, in the above technical solution, the rope is a high-strength nylon rope or a steel wire rope.

[0125] Furthermore, in the above technical solution, each ladder segment 11 of the vertical ladder 10 is provided with steps, and the steps are provided with anti-slip textures or anti-slip strips.

[0127] Specific implementation steps

[0128] Step 1: Video Acquisition and Transmission

[0129] Camera capture: The camera captures images of the work site and transmits the video stream to the controller via wired or wireless means.

[0130] Video compression: The controller uses H.264 / H.265 encoding algorithms to compress the video stream and reduce the amount of data.

[0131] Video transmission: The compressed video stream is transmitted to the display screen via the RTSP protocol.

[0132] Step 2: Image Recognition and Pose Estimation

[0133] Image recognition: The controller uses libraries such as OpenCV to perform image recognition on video frames and identify key objects.

[0134] Pose estimation: The SLAM algorithm is used to estimate the camera pose and determine the position of the object.

[0135] Information extraction: Based on the recognition results, extract the information that needs to be displayed.

[0136] Step 3: Information Overlay and Display

[0137] Information overlay: Using rendering engines such as OpenGL or Unity to overlay extracted information onto the video frame.

[0138] Real-time display: The controller decompresses the processed video footage and displays it on the screen in real time.

[0139] Step 4: User Interaction and Feedback

[0140] User input: If the system supports voice input, NLP technology is used to convert voice commands into visual guidance information.

[0141] Feedback shows that displaying user input results in a visual format on the screen helps operators understand and perform tasks.

[0142] A drainage hole is provided at the bottom of the waterproof casing so that even if a small amount of water gets in, it can be drained in time. The drainage hole should be equipped with a waterproof mesh to prevent foreign objects from entering.

[0143] Waterproof cable:

[0144] Type: Uses waterproof cables to connect the camera and display screen, ensuring the cable's waterproof performance in pool environments.

[0145] Materials: The cable is made of waterproof materials, such as waterproof PVC sheath, and is equipped with waterproof connectors.

[0146] Specifically, the principle of this invention is:

[0147] Vertical ladder design:

[0148] Top suspension: The vertical ladder is fixed to the top structure of the pool by top suspension, ensuring the vertical stability of the ladder;

[0149] Horizontal support: One end of the horizontal support is welded to the vertical ladder or fixed by bolts, and the other end is fixed to the pool wall, which enhances the structural stability of the vertical ladder;

[0150] Adjustable design: The length of the horizontal support is adjustable via a telescopic rod, adapting to pool walls of different widths and ensuring system flexibility;

[0151] Design of the hanging cage for operation:

[0152] Rectangular frame structure: The working cage is welded from square steel pipes to form a rectangular frame structure, and is surrounded by a fence, providing a safe and reliable working environment for workers;

[0153] Quick-release buckles: The work cage is connected to the vertical ladder by ropes, and the buckles are designed to be quick-release, which makes it easy to quickly adjust the height of the work cage.

[0154] Door locking mechanism: A door is provided on one side of the work cage, and a safety lock is installed on the door to ensure the safety of workers when entering and exiting;

[0155] Design of the fixing device:

[0156] Pull-out safety clamp: The pull-out safety clamp consists of two symmetrical clamping plates connected by a spring. One end of the clamping plate is fixed to both sides of the vertical ladder, and the other end has an outward-protruding hook-like structure. The tension of the spring tightly grips the edge of the vertical ladder, enhancing the fixing effect.

[0157] Top hanging point: The top hanging point is fixed to the top structure of the pool by drilling holes and using expansion bolts, which ensures the structural stability of the vertical hanging ladder;

[0158] Anti-slip design:

[0159] Anti-slip steps: Each section of the vertical ladder is equipped with steps, which have anti-slip textures or strips to enhance friction during climbing and reduce the risk of slipping.

[0160] Anti-slip clamps: The clamps of the safety clamps are equipped with rubber pads or other anti-slip materials, which increases the friction between the clamps and the vertical hanging ladder and prevents slippage.

[0161] Visualized task assistance system:

[0162] Cameras and displays: The system is equipped with cameras and displays, which use video transmission technology to display the scene of the work site to the workers in real time, thus enhancing the workers' field of vision.

[0163] AR technology: The system integrates AR technology to overlay guidance information onto the video screen, improving the accuracy and efficiency of the operation;

[0164] Video compression and transmission: The controller uses the H.264 or H.265 video compression standard to process the video stream and transmits it via the RTSP protocol, ensuring high efficiency in video transmission;

[0165] Image recognition and pose estimation: The system integrates OpenCV image recognition algorithm and SLAM pose estimation algorithm, and superimposes guidance information on the video image to improve the system's intelligence.
