Description

Technical Field

[0001] This invention relates to the field of building construction technology, and specifically to an intelligent concrete curing system. Background Technology

[0002] With the rapid development of China's wind power industry and the continuous improvement of turbine power generation capacity, the requirements for foundations are also increasing. The insulation and moisture retention of large-volume concrete are crucial for ensuring the quality of wind turbine foundation construction. As a key structure bearing the weight of the entire turbine and transferring loads to the ground, the concrete strength and crack resistance of the wind turbine foundation directly affect the safe operating life of the unit. Due to the large volume and thickness of concrete in wind turbine foundations, a large amount of heat is released during cement hydration, causing a rapid rise in the internal temperature of the concrete, while the surface cools down quickly due to ambient temperature, easily creating a large temperature difference between the inside and outside. This temperature difference causes compressive stress inside the concrete and tensile stress on the surface. When the tensile stress exceeds the tensile strength of the concrete, temperature cracks will appear, seriously affecting the integrity and durability of the foundation.

[0003] In terms of moisture retention, after the large-volume concrete is poured, the surface needs to be kept moist to ensure that the cement is fully hydrated. This is especially true in high-altitude, high-latitude temperate arid continental climate regions where wind farms are located. The air is dry, the wind speed is high, and the rate of moisture evaporation is much faster than in ordinary areas. If only traditional covering and watering curing methods are used, it will not only be difficult to maintain a continuous moist state on the concrete surface, but uneven moisture evaporation may also lead to increased local shrinkage and increase the risk of cracking. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a concrete intelligent curing system. This invention installs a humidity sensor on the concrete foundation to detect whether the concrete foundation is dry. If it is dry, the control box controls the electric valve to open and water the concrete foundation through the curing water pipe.

[0005] A technical solution to achieve the above objectives is a concrete intelligent curing system, installed on a concrete foundation, wherein the curing structure includes:

[0006] The water tank is installed on the concrete foundation;

[0007] Several curing water pipes are installed on the concrete foundation, and the several curing water pipes are arranged at intervals on the concrete foundation. Several spray holes are formed at the bottom of the curing water pipes.

[0008] An outlet water pipe connects the water tank and several maintenance water pipes, and an electric valve is installed between the outlet water pipe and the water tank;

[0009] Several humidity sensors are installed on the concrete foundation;

[0010] A control box is installed on the concrete foundation. The control box is communicatively connected to the humidity sensor and the electric valve. The humidity sensor transmits humidity information of the concrete foundation to the control box, and the control box controls the opening and closing of the electric valve.

[0011] A curing film is placed on top of the concrete foundation, and the curing water pipe is located below the curing film.

[0012] Furthermore, the maintenance water pipe is composed of several water pipe unit segments spliced ​​together. One end of each water pipe unit segment has a socket ring with an installation slot. A rod is slidably disposed in the installation slot. An installation block is provided at the end of each water pipe unit segment away from the socket ring. The installation block forms a limiting groove corresponding to the rod. The installation block of the water pipe unit segment is inserted into the installation slot of another water pipe unit segment, and the rod is slid so that it slides into the limiting groove to fix the two water pipe unit segments.

[0013] Furthermore, the side of the insertion rod away from the water pipe unit segment has an inclined surface, and the side of the mounting block away from the water pipe unit segment has an arc-shaped surface. When the mounting block is inserted into the mounting slot, the inclined surface of the insertion rod slides along the arc of the arc-shaped surface and is inserted into the limiting groove.

[0017] A first sliding block is fixedly disposed on the outer ring of the fixed ring, and a first magnetic block is disposed on the side of the first sliding block near the water pipe unit section; and

[0018] A second sliding block is slidably disposed on the fixed ring. The second sliding block is disposed on the side of the first sliding block near the water pipe unit segment. By sliding the second sliding block, the mounting slot is formed between the first sliding block and the second sliding block. The second sliding block has a second magnetic block corresponding to the first magnetic block.

[0019] Furthermore, a mounting groove is formed on the side of the second sliding block away from the water pipe unit segment. A limit rod is slidably and adjustablely installed in the mounting groove. One end of the limit rod is fixedly installed on the first sliding block, and a limit spring is provided between the other end of the limit rod and the inner wall of the mounting groove.

[0020] Furthermore, a portion of the fixing ring extends toward the side away from the water pipe unit segment to form a sealing section, and a first sealing ring is provided on the outer ring of the sealing section;

[0021] The inner ring of the water pipe unit section near the socket ring is provided with a second sealing ring corresponding to the first sealing ring. By inserting the mounting block into the socket ring, the first sealing ring and the second sealing ring seal the gap between the sealing section and the other water pipe unit section.

[0022] Furthermore, the side wall of the water tank is connected to a water inlet pipe.

[0023] Furthermore, the top of the curing film is covered with geotextile.

[0024] Furthermore, the top of the geotextile is covered with insulating cotton.

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] See Figure 1 A concrete intelligent curing system is installed on a concrete foundation 1. The curing structure includes: a water tank 3 installed on the concrete foundation 1; a plurality of curing water pipes 6 installed on the concrete foundation 1, the plurality of curing water pipes 6 being arranged at intervals on the concrete foundation 1, and a plurality of spray holes 601 forming at the bottom of the curing water pipes 6; a water outlet pipe 4 connecting the water tank 3 and the plurality of curing water pipes 6, and an electric valve 5 being installed between the water outlet pipe 4 and the water tank 3; a plurality of humidity sensors 7 installed on the concrete foundation 1; a control box 12 installed on the concrete foundation 1, the control box 12 being communicatively connected to the humidity sensors 7 and the electric valve 5, the humidity sensors 7 transmitting the humidity information of the concrete foundation to the control box 12, and the control box 12 controlling the electric valve 5 to open or close; and a curing film 13 covering the top of the concrete foundation, with the curing water pipes 6 located below the curing film 13.

[0036] In a preferred embodiment of this invention, after the concrete foundation 1 is poured, a water tank 3 is placed inside the concrete foundation 1, and a curing water pipe 6 and a water outlet pipe 4 are arranged on the concrete foundation 1. Preferably, in this embodiment, the concrete foundation 1 is a circular structure that is low at both ends and high in the middle. An upper support platform is set at the center of the concrete foundation 1, and the water tank 3 and control box 12 are set on the top of the upper support platform. During the arrangement, the curing water pipe 6 is arranged into several rings of different sizes. The ring-shaped curing water pipes 6 are arranged sequentially from the outer periphery of the concrete foundation 1 to the center of the concrete foundation 1 in descending order of size. The curing water pipe 6 is elliptical in shape and is made of linear low-density polyethylene (LLDPE) or bio-based polyethylene (PE) polymer braided tape. Spray holes 60 are set at the bottom of the curing water pipe 6. 1. Multiple humidity sensors 7 are arranged in a ring along the curing water pipe 6 on the concrete foundation 1. The humidity sensors 7 can detect the humidity of the concrete foundation 1. In this embodiment, three humidity sensors 7 are provided. The three humidity sensors 7 are respectively located at the center of the upper platform, the middle of the concrete foundation 1, and the outer perimeter of the concrete foundation 1, so as to detect the humidity at different locations of the concrete foundation 1. The electric valve 5 and the humidity sensors 7 can be connected to the control box 12 via Bluetooth or via wire. The humidity sensor 7 detects whether the concrete foundation 1 is dry. If it is dry, the control box 12 controls the electric valve 5 to open and water the concrete foundation 1 through the curing water pipe 6. A curing film 13 is covered on the concrete foundation 1 to reduce the loss of water from the concrete foundation 1.

[0037] Furthermore, the humidity sensor 7 uses a capacitive HS1101 or a digital DHT22 as the sensing element. The sensor is connected to the Arduino Uno microcontroller via an I²C interface. The miniature electric valve 5 is connected to the Arduino Uno microcontroller via a relay module. The Arduino Uno microcontroller serves as the control core, presets the humidity threshold and hysteresis range (±5% to avoid frequent valve operation), reads the sensor data in real time and converts it into a humidity value. If the humidity is less than the lower threshold (90%), the relay is triggered to conduct, and the valve opens to replenish water. If the humidity is greater than the upper threshold (95%), the relay is deactivated, and the valve closes.

[0038] Furthermore, a 5V / 100mA solar photovoltaic panel 9 is installed on the upper part of the water tank 3, tilted at an angle of 30° and facing southwest; the photovoltaic panel is connected to an 18650 lithium battery pack (2000mAh) through wires. The battery pack is equipped with a TP4056 power management IC and a 5V voltage regulator module to power the electric valve 5, humidity sensor 7 and control box 12.

[0039] Furthermore, the humidity sensor is connected to the control box 12 via data transmission line 8, the control box 12 is connected to the electric valve via valve control line 11, and the solar photovoltaic panel is connected to the electric valve, the control box 12, and the humidity sensor via power line 10.

[0040] Furthermore, the maintenance water pipe 6 is composed of several pipe unit segments spliced ​​together. One end of each pipe unit segment has a socket ring 602 with an installation slot. A rod 606 is slidably disposed within the installation slot. An installation block is provided at the end of each pipe unit segment away from the socket ring 602. The installation block forms a limiting groove corresponding to the rod 606. The installation block of one pipe unit segment is inserted into the installation slot of another pipe unit segment, and the rod 606 is slid into the limiting groove to fix the two pipe unit segments. Preferably, there are two installation slots, opposite each other on the socket ring 602. Two installation blocks are provided corresponding to the two installation slots. By fixing the two installation slots and the two installation blocks together, the two pipe unit segments can be more stably fixed.

[0041] Furthermore, the side of the insertion rod 606 away from the water pipe unit segment has an inclined surface, and the side of the mounting block away from the water pipe unit segment has an arc-shaped surface. When the mounting block is inserted into the mounting slot, the inclined surface of the insertion rod 606 slides along the arc of the arc-shaped surface and is inserted into the limiting groove. When the mounting block is inserted into the mounting slot, the inclined surface of the insertion rod 606 fits against the arc-shaped surface of the mounting block, causing the insertion rod 606 to slide along the arc of the arc-shaped surface, thereby allowing the insertion rod 606 to slide into the limiting groove.

[0042] Furthermore, a locking spring 603 is provided between the insertion rod 606 and the inner wall of the mounting slot. When the inclined surface of the insertion rod 606 is in contact with the arc-shaped surface of the mounting block, the insertion rod 606 moves along the arc-shaped surface and presses the locking spring 603, compressing the locking spring 603. When the insertion rod 606 moves to the position of the limiting groove, the locking spring 603 pushes against the insertion rod 606, so that the insertion rod 606 is inserted into the limiting groove.

[0043] Furthermore, the mounting block includes: a fixing ring 607 fixedly mounted on the end of the water pipe unit segment, the outer diameter of the fixing ring 607 being smaller than the inner diameter of the water pipe unit segment; a first sliding block 608 fixedly disposed on the outer ring of the fixing ring 607, the first sliding block 608 having a first magnetic block 614 disposed on the side near the water pipe unit segment; and a second sliding block slidably disposed on the fixing ring 607, the second sliding block being disposed on the side of the first sliding block 608 near the water pipe unit segment, and by sliding the second sliding block, the mounting slot is formed between the first sliding block 608 and the second sliding block, the second sliding block having a second magnetic block 613 corresponding to the first magnetic block 614. Preferably, when installing two water pipe unit segments, the first sliding block 608 and the second sliding block are first separated to form the mounting slot between them. Then, the insertion rod 606 of the mounting plug of the other water pipe unit segment is installed into the mounting slot to complete the splicing of the two water pipe unit segments. When it is necessary to remove the two water pipe unit segments, the second sliding block is slid away from the first sliding block 608 to increase the gap in the mounting slot. Then, the other water pipe unit segment is moved towards the second sliding block so that the inclined surface of the insertion rod 606 of the other water pipe unit segment is attached to the side wall of the second sliding block. The insertion rod 606 slides away from the second sliding block, and the locking spring 603 of the insertion rod 606 is compressed, thereby causing the insertion rod 606 to disengage from the mounting slot.

[0044] Furthermore, a mounting groove is formed on the side of the second sliding block away from the water pipe unit segment. A limiting rod 611 is slidably and adjustablely installed in the mounting groove. One end of the limiting rod 611 is fixedly installed to the first sliding block 608, and a limiting spring 612 is provided between the other end of the limiting rod 611 and the inner wall of the mounting groove. This limiting rod 611 prevents the second sliding block from moving too far away from the first sliding block 608.

[0045] Furthermore, a portion of the fixing ring 607 extends away from the water pipe unit segment to form a sealing section, and a first sealing ring 610 is provided on the outer ring of the sealing section; a second sealing ring 605 is provided on the inner ring of the water pipe unit segment near the socket ring 602, corresponding to the first sealing ring 610. By inserting the mounting block into the socket ring 602, the first sealing ring 610 and the second sealing ring 605 seal the gap between the sealing section and the other water pipe unit segment. The tight fit between the first sealing ring 610 and the second sealing ring 605 increases the waterproof effect between the second sealing ring 605 and the first sealing ring 610, thereby preventing water leakage between the water pipe unit segments.

[0046] Furthermore, the side wall of the water tank 3 is connected to a water inlet pipe 2. Preferably, a liquid level sensor is installed inside the maintenance water tank 3. When the water level is below 1 / 3, the control box 12 controls a water inlet device, such as a water truck, located outside the concrete foundation 1. This water inlet device is connected to the water inlet pipe 2 and replenishes water through the water inlet pipe 2. Water inlet stops when the water tank 3 is full.

[0047] Furthermore, the top of the curing film 13 is covered with geotextile 14.

[0048] Furthermore, the top of the geotextile 14 is covered with thermal insulation cotton 15.

[0049] The following describes the usage process of the intelligent concrete curing system of the present invention.

[0050] After the concrete foundation 1 structure is poured and reaches initial setting, the surface of the concrete foundation 1 is smoothed to ensure a flat surface, providing a foundation for the subsequent laying of the curing water pipes 6 and the covering layer. Multiple layers of curing water pipes 6 are evenly laid in a ring around the conical slope of the concrete foundation 1. Each curing water pipe 6 is assembled from several pipe unit segments to form a closed ring. After the curing water pipes 6 are laid, a curing film 13 is laid on the surface of the concrete foundation 1. This curing film 13 is made of 0.12mm thick polyethylene film, covering the entire concrete surface and the curing water pipes 6. The edge of the curing film 13 extends 50cm beyond the edge of the concrete foundation 1 and is fixed. Then, geotextile 14 is laid on top of the curing film 13, adhering tightly to it and with sealed edges. Insulation cotton 15 is then laid on top of the geotextile 14. A 5cm thick geotextile 14 is used to cover the concrete foundation 1, with weights used to press the edges to prevent wind displacement. Three humidity sensors 7 are installed inside the curing film 13, located at the center, middle ring, and outer ring of the concrete foundation 1, respectively. The sensors are capacitive HS1101 type and connected to the control box 12 via waterproof cables. A large-capacity water tank 3 is installed at the top of the center of the concrete foundation 1. A water outlet is installed at the bottom of the water tank 3, which is connected to the curing water pipe 6 and the outlet pipe via a miniature electric valve 5. A water inlet is installed at the top, connected to the water inlet pipe 2 located outside the foundation. The end of the water inlet pipe 2 is equipped with a quick connector for water truck replenishment. The electric valve 5 is powered by DC 12V and connected to the microcontroller in the control box 12 via a relay module. A 5V / 100mA cable is installed on top of the water tank 3. The solar photovoltaic panel 9 is tilted at a 30° angle, facing southwest. A preset humidity threshold is set in the control box 12: lower limit 90%, upper limit 95%, hysteresis ±5%. The data transmission function of the humidity sensor 7 is tested to ensure real-time upload of humidity data to the control box 12. The opening and closing response of the electric valve 5 is tested to verify the logic of "valve opening when humidity < 90%, valve closing when humidity > 95%" is normal. The humidity sensor 7 monitors the humidity inside the curing film 13 in real time, and the data is transmitted to the control box 12 via the I²C interface. When the detected humidity is below 90%, the control box 12 triggers a relay to open the electric valve 5, and water from the water tank 3 is evenly dripped onto the concrete surface through the spray holes 601, forming a closed, moisturizing environment through the curing film 13. When the humidity is above 95%, the relay disconnects, the electric valve 5 closes, and water supply stops to prevent excessive moisture.

[0051] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
