[0002] After the prefabricated segments of the wind turbine hybrid tower are demoulded, they are usually stored in the open air for maintenance at the component factory. However, this traditional storage method faces many technical difficulties: limited stacking space in the factory leads to chaotic and disorderly storage; extensive maintenance methods result in untimely watering maintenance; and the mismatch between the production sequence of the prefabricated segments and the storage location affects management efficiency. These problems not only reduce the utilization rate of the factory space, but may also lead to the inability to ensure the later strength of the components. With the increase in the number of prefabricated segments, the traditional watering maintenance method consumes a lot of water resources and labor costs, and it is difficult to achieve accurate timed and quantitative spraying. Especially in extreme weather such as wind, rain or low temperatures, the open air storage environment seriously affects the quality of segment repair and surface spraying construction, thereby slowing down the construction progress of the entire wind turbine hybrid tower.

[0017] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0018] See also Figures 1 to 6 The present invention provides a storage and maintenance device for prefabricated segments, comprising: Base 2, comprising two parallel steel beams; Support units are arranged at intervals on the base 2. Each group of support units includes an arc-shaped channel steel 3 and a rubber pad 4 arranged thereon, which is used to support the prefabricated pipe segment 10; The spray unit 5 includes spray nozzles 51 disposed between adjacent support units and is used to spray water for curing the prefabricated segments 10; The monitoring unit includes a pressure sensor provided below the rubber pad 4 and a temperature and humidity sensor 7 on the side of the support unit; The control system is connected to the spray unit 5, the monitoring unit and the foldable tarpaulin assembly 8 by signals.

[0019] The storage and maintenance device for prefabricated pipe segments provided by the present invention adopts a support unit in conjunction with a monitoring unit to achieve precise positioning and stable support of the prefabricated pipe segments, greatly improving the site space utilization rate; the spray unit is combined with the monitoring unit to automatically adjust the spray parameters according to environmental conditions, which not only ensures the maintenance quality but also significantly saves water resources; the foldable tarpaulin assembly provides all-weather protection and effectively copes with various severe weather conditions; the control system realizes remote monitoring and management, allowing operators to grasp the status of the pipe segments at any time and make necessary adjustments; it not only significantly improves the maintenance quality and construction efficiency of the prefabricated pipe segments, but also reduces labor costs and water resource consumption, has outstanding economic and social benefits, and is suitable for the storage and maintenance needs of various prefabricated pipe segments.

[0020] The base 2 is made of high-strength materials such as channel steel or I-steel, and provides a basic carrier for the installation of the support unit, the spray unit 5 and the electric control pipeline, and the installation of the foldable tarpaulin assembly 8.

[0021] Furthermore, the support unit, consisting of curved channel steel 3, rubber pads 4, and a self-locking device, primarily supports the prefabricated segments 10. When a prefabricated segment 10 is placed on the support unit, the pressure triggers a pressure sensor, which provides feedback to the control interface, indicating that the position is occupied. Otherwise, it indicates that the position is unloaded. Furthermore, the curved channel steel 3 can be moved in four directions: forward, backward, left, and right, facilitating adjustment of the support unit based on segment size.

[0022] A continuous guide rail 9 is provided on the inner sidewall of the steel beam, and the support unit slides in engagement with the guide rail 9 via a slider. The slider of the support unit is also equipped with a magnetic self-locking device, comprising: a magnetic box fixedly mounted on the bottom of the slider; a neodymium iron boron permanent magnet embedded within the magnetic box; and a magnetic control switch located on the side of the magnetic box. The magnetic control switch switches the magnetic self-locking device on and off. When on, the neodymium iron boron permanent magnet generates magnetic attraction, tightly securing the slider to the guide rail 9; when off, the magnetic attraction is released, enabling sliding adjustment.

[0023] The spray unit 5 is mainly used for spraying water on the prefabricated pipe segments 10 for maintenance. The opening and closing of the spray unit 5 is controlled by a temperature and humidity sensor, and can also be controlled through a control interface.

[0024] The temperature and humidity sensor 7 is mainly used for real-time dynamic monitoring of the environment around the prefabricated pipe segment 10, and then controls the opening and closing of the spray unit 5, so as to achieve the purpose of no one guarding around the clock.

[0025] The foldable tarpaulin assembly 8 consists of a foldable frame 82 and a tarpaulin, which is slidably connected to the base 2. The foldable frames 82 are a downward-facing, shaped structure, and the tarpaulin is fixedly covered on the outer surfaces of the foldable frames 82. The upper flange of the steel beam is provided with a slide rail, and the ends of the foldable frames 82 are slidably connected to the slide rail via rollers 81. The foldable tarpaulin assembly 8 is normally stowed and can be unfolded as needed to provide full coverage of the pipe segments within the entire device, thereby creating a suitable and stable working environment and reducing the impact of external factors on the quality of the components.

[0026] The control system includes: a control box 1 located at a corner of the base 2; a PLC controller located inside the control box 1, which is signal-connected to the spray unit 5, the monitoring unit and the foldable tarpaulin assembly 8; a touch screen display located on the surface of the control box 1; a 5G communication module integrated in the PLC controller; and a warning light 6 located on the outer surface of the control box 1.

[0027] The control system is mainly used to control the output display, input control, opening and closing of the sprinkler system, and opening and closing of the foldable tarpaulin of the entire device. It can also be interconnected with the APP in the mobile phone through 5G technology to realize remote monitoring and management by management personnel.

[0028] The control interface realizes two-way interaction of output and input through the touch screen display. While displaying values such as vacancy, segment number, production date, temperature and humidity, the control system can be called through interface operation to realize different functions of the device.

[0029] The alarm device is a red warning light. When you need to locate the position of a certain pipe segment, you can place an order with one click through the mobile phone APP. At this time, the red warning light will light up, which plays a role in quick positioning.

[0030] The present invention further provides a method for storing and curing prefabricated segments, which is performed using the above-mentioned storage and curing device for prefabricated segments 10 and includes the following steps: S1. Adjust the spacing between the support units, hoist the prefabricated segments 10 above the support units, and confirm their position using pressure sensors. S2. Inputting information of the prefabricated segments 10 through the control system and starting the curing process, and recording the curing data; S3. Control the opening and closing of the spray unit 5 and the foldable tarpaulin assembly 8 according to the data of the monitoring unit, and lift the prefabricated pipe segment 10 after the curing process is completed.

[0031] Furthermore, the spray unit 5 adopts an intermittent mode, and the spraying duration and interval are dynamically adjusted according to the maintenance stage. Maintenance data is transmitted to mobile terminals in real time via the 5G network for remote monitoring and emergency control.

[0032] The specific implementation of the device in this application is as follows: First, assemble the steel base 2 and secure it to a predetermined location within the factory. A support unit consisting of curved channel steel 3 and rubber pads 4 is connected to the guide rails 9 on the inner side of the steel beam of the base 2 via sliders, forming an adjustable segment support structure. Based on the dimensions of the prefabricated segments 10, the support unit is slid along the guide rails 9 to adjust the spacing to the desired position and then locked securely.

[0033] The prefabricated segment 10 is hoisted onto the support unit, ensuring that the bottom of the segment is fully aligned with the rubber pad 4. The segment's position is confirmed by a pressure sensor embedded below the rubber pad 4. Basic information about the prefabricated segment 10, such as its serial number and production date, is then entered through the touchscreen display of the control box 1. The control system automatically begins recording the curing age.

[0034] During operation, temperature and humidity sensors 7 located on the sides of the support units monitor environmental parameters in real time. When the humidity is detected to be below a set threshold, the control system automatically activates the spray unit 5, spraying and curing the prefabricated segments 10 through adjustable spray nozzles 51 between adjacent support units. When the temperature drops below a set threshold, the foldable tarpaulin assembly 8 is deployed along the slide rails on the upper flange of the steel beam, creating a thermally insulated curing space. The tarpaulin assembly consists of multiple sets of ⌚-shaped frames connected in series via hinged axes. When deployed, it forms a continuous, all-around covering structure, creating a suitable and stable working environment and minimizing the impact of external factors on component quality.

[0035] During maintenance, operators can remotely monitor the status of the segments through a control system integrated with a 5G communication module. When a precast segment 10 reaches its scheduled maintenance age, the system triggers a flashing warning light 6 and sends a notification via a mobile app, facilitating quick location and lifting operations.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. If these modifications and variations fall within the scope of the claims of the present invention and their equivalent technologies, they should be considered to be within the scope of protection of the present invention.
