Description
TECHNICAL FIELD
[0001] The present application relates to the field of concrete curing, in particular to a concrete intelligent heat preservation device and control system. BACKGROUND
[0002] Extreme cold weather in winter poses a severe challenge to concrete construction. Mass concrete (such as bridge piers, tunnel lining, water conservancy dam foundation and other structures) needs to go through a critical hardening period (usually 7-28 days) after pouring. Although the cement hydration reaction is significantly slowed down due to low temperature, the concrete still releases a small amount of hydration heat inside. However, the heat of the external environment is quickly lost, which easily leads to an extreme temperature difference between the inside and outside of the concrete, causing temperature and humidity imbalance, curing failure and other hazards.
[0003] In view of the winter concrete curing problem, the industry currently mainly relies on the following technologies: 1. Passive thermal insulation material covering: commonly used materials such as straw mats, cotton quilts or rock wool boards are directly covered on the surface of the concrete, which has a high thermal conductivity and limited thermal insulation efficiency. Moreover, the materials are easily blown away by strong winds and need to be reinforced frequently by hand. At night, the materials themselves cannot maintain the temperature of the concrete surface above 0℃, and additional coal / electric heating equipment is needed to assist in heating, but there are fire hazards and energy waste. Some projects use polyurethane foam boards to replace traditional thermal insulation materials, but the material is brittle and poorly adhered to the surface of the concrete, and does not have the function of active heating, so it is difficult to cope with sustained low temperatures relying only on its own heat accumulation.
[0004] 2. Simple heating and spraying system: Some projects use electric blankets or hot water pipes to directly contact the surface of the concrete for heating, but the electric blanket is easily overheated in some local areas due to the unevenness of the concrete surface, which destroys the balance of the hydration reaction. The hot water pipe has the problem of uneven heating, and the pipe is easily frozen and blocked. Moreover, the heat is easily conducted to the air instead of the concrete inside, resulting in low energy utilization.

[0022] The technical solution of the present invention will be clearly and completely described below with reference to preferred embodiments. 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.
[0023] like Figures 1 to 8 As shown, a concrete intelligent insulation device includes an insulation blanket, a water tank 10, a control box 9, and a first temperature sensor 5. Hollow bags 3 are detachably connected to all four sides of the insulation blanket. The hollow bags 3 are filled with an anti-freezing liquid, and a sealing plug 4 is detachably connected to the top of the inner cavity of the hollow bag 3. The hollow bags 3, when filled with the anti-freezing liquid, use their weight to fix the position of the insulation blanket, preventing it from warping due to wind or other factors during use. The sealing plug 4 seals the inner cavity of the hollow bag 3; when the sealing plug 4 is open, the liquid inside the hollow bag 3 can drain out, facilitating the storage of the device. The material of the anti-freezing liquid can be selected as needed and is not limited here.
[0024] The thermal insulation blanket adopts a modular and detachable structural design, including a blanket body 1. Adjacent blanket bodies 1 are stably spliced together through a quick-connect mechanism. With this design, the size of the thermal insulation blanket can be adjusted according to the area of the concrete to be insulated during actual use, improving the adaptability of the application. Furthermore, when a part of the thermal insulation blanket is damaged, only the problematic module needs to be disassembled for replacement or repair, improving maintenance convenience. During transportation and storage, the thermal insulation blanket can be disassembled into small pieces, improving transportation and storage convenience.
[0025] The top of the blanket body 1 is provided with sealing gasket 6 and sealing gasket 8. The seam between two adjacent blanket bodies 1 is sealed by sealing gasket 6 and sealing gasket 8, which reduces heat loss of the insulation blanket and improves the performance of the insulation blanket. In addition, sealing gasket 6 and sealing gasket 8 have the characteristics of being airtight and flame retardant, which can prevent air from entering the interior of the insulation blanket, reduce air circulation, reduce fire hazards, and improve the safety of the insulation blanket.
[0026] In Example 1, adjacent blankets 1 are connected by Velcro. Each of the four sides of the top of blanket 1 is provided with a sealing gasket 6, a sealing gasket 8, a Velcro 11, and another Velcro 11. Sealing gasket 6 is positioned opposite Velcro 11, and sealing gasket 8 is positioned opposite Velcro 11. The top and bottom of sealing gasket 6 and the bottom of sealing gasket 8 are each provided with Velcro tabs 40 that fit the Velcro 11. The Velcro tabs 40 and Velcro 11 allow for quick assembly and disassembly of adjacent blankets 1.
[0027] In Example 2, the hollow bag 3 and the thermal blanket are connected by Velcro. The bottom of the hollow bag 3 is provided with a connecting strip 2, and the bottom of the connecting strip 2 is provided with a Velcro female 11 or a Velcro female 40. With Velcro, the hollow bag 3 and the thermal blanket can be quickly assembled and disassembled. In addition, when using this application, the user can adjust the position and number of hollow bags 3 according to the needs, thereby improving the adaptability of this application.
[0028] The blanket body 1 has a multi-layer composite structure, which includes, from bottom to top, an isolation layer 16, a water spray and drainage hose layer 17, a heating cable layer 18, a heat insulation layer 19, and an airtight surface layer 20.
[0029] The isolation layer 16 has a mesh-like groove on its top, allowing water sprayed from the water spray hose layer 17 to be evenly distributed on the isolation layer 16. The isolation layer 16 also has uniformly distributed micro-permeable holes, and a perforated heat-conducting pad is located at its bottom. Through the isolation layer 16, the moisturizing liquid sprayed from the water spray hose layer 17 can be applied to the concrete through the micro-permeable holes and the perforated heat-conducting pad, thus moisturizing the concrete. The perforated heat-conducting pad, acting as a protective medium between the isolation layer 16 and the concrete, prevents the micro-permeable holes from clogging due to direct contact between the concrete and the isolation layer 16. Furthermore, its excellent thermal conductivity ensures even heat dissipation, significantly improving the uniformity of the concrete's insulation effect. The materials of the perforated heat-conducting pad and the isolation layer 16 can be customized according to requirements and are not limited here.
[0030] The water spray hose layer 17 includes a heat-conducting body 37, on which a water spray hose 23, a humidity sensor 21, and a second temperature sensor 22 are embedded. The humidity sensor 21 is arranged in a grid pattern, and the second temperature sensor 22 is evenly distributed on the heat-conducting body 37. The control system of this application uses the humidity sensor 21 to monitor the humidity of the concrete surface in real time. Based on the humidity status, the control system of this application can adjust the moisturizing measures according to the actual situation to ensure that the concrete is always under suitable humidity conditions, ensuring that the hydration reaction proceeds fully. The control system of this application uses the second temperature sensor 22 to detect the temperature of the concrete.
[0031] The bottom of the water spray hose 23 is uniformly provided with drainage holes 32, which are located in the outer area of the heat-conducting body 37. Water inside the water spray hose 23 can be sprayed out through the drainage holes 32. The inner cavity of the water spray hose 23 is provided with a cleaning assembly adapted to the drainage holes 32. The cleaning assembly includes a guide rod 33 connected to the top of the inner cavity of the water spray hose 23. The outer ring of the guide rod 33 is movably fitted with a cleaning block 31 adapted to the drainage hole 32. The cleaning block 31 is connected to the top of the inner cavity of the water spray hose 23 through a first spring 30. Electromagnets 28 are provided on both sides of the drainage hole 32. The electromagnets 28 are embedded in the pipe wall of the water spray hose 23. When the electromagnets 28 are energized, the electromagnets 28 and the cleaning block 31 are magnetically attracted to each other. With the setting of the cleaning assembly, this application can realize automatic cleaning of the drainage holes 32 during use, avoiding the impact of the uniformity of concrete moisture retention due to the blockage of the drainage holes 32. When electromagnet 28 is de-energized, it can be reset by the restoring force of the first spring 30, at which point the drain hole 32 is open for drainage. The material of the cleaning block 31 can be set according to requirements and is not limited here.
[0032] The water spray hoses 23 of adjacent blanket bodies 1 are directly connected through quick-connect couplings to form a continuous water supply path. The quick-connect couplings include a first connector 15 and a second connector 14. One end of the water spray hose 23 is provided with the first connector 15, and the other end of the water spray hose 23 is provided with the second connector 14. The fluid delivery port of the first connector 15 is provided with an insertion tube 24, and the bottom end of the insertion tube 24 is uniformly provided with drainage holes 25. The top of the inner cavity of the second connector 14 is provided with a through hole adapted to the insertion tube 24. The inner cavity of the second connector 14 is connected to a sealing plate 26 through a second spring 27 and a guide rod 29. The sealing plate 26 is adapted to the through hole. When the insertion tube 24 is inserted into the through hole, the insertion tube 24 will squeeze the sealing plate 26, and the sealing plate 26 will move away from the through hole. When the insertion tube 24 is fully inserted into the through hole, the drain hole 25 is located in the inner cavity of the second connector 14. Through the drain hole 25, the inner cavity of the first connector 15 and the inner cavity of the second connector 14 are in a state of communication. There is damping between the insertion tube 24 and the through hole. Under the action of this damping force, the restriction on the insertion tube 24 is released, and the position of the insertion tube 24 can remain unchanged. When the first connector 15 and the second connector 14 are separated, the sealing plate 26 can be reset under the action of the rebound force of the second spring 27, thereby achieving the sealing of the second connector 14. In addition, when this application is in use, the unused first connector 15 can be sealed by the first sealing cover 7, thereby preventing water from leaking through the unused first connector 15 and the unused second connector 14 when water is injected into the water supply passage.
[0033] The heating cable layer 18 includes heating cables 38 and heat-conducting blocks 39. The heat-conducting blocks 39 are filled between the heating cables 38, and the heating cables 38 are in contact with the heat-conducting body 37. The heat-conducting blocks 39 and the heat-conducting body 37 ensure that the heat generated when the heating cables 38 are energized is evenly distributed within the insulation blanket, improving the uniformity of concrete insulation. The materials of both the heat-conducting blocks 39 and the heat-conducting body 37 can be chosen according to requirements and are not limited here. A flame-retardant coating is provided on the top of the water spray hose layer 17 and the bottom of the insulation layer 19. This flame-retardant coating inhibits combustion reactions and improves the safety of the insulation blanket.
[0034] The outlet of the water tank 10 is connected to the inlet of the insulation blanket via a quick-connect coupling. The connecting pipe 35 between the outlet and inlet of the water tank 10, as well as the outer surface of the water tank 10, are covered with insulation pads. The water tank 10 integrates a heating module and a third temperature sensor 36. Through the third temperature sensor 36 and the heating module, this application uses the third temperature sensor 36 to detect the water temperature in the water tank 10 during use. When the water temperature is lower than a preset threshold, the control system can control the heating module to operate. The heat emitted by the heating module when powered on heats the water, preventing it from freezing. Furthermore, the connecting pipe 35 integrates a heating wire. When it is necessary to keep the concrete moist, the heating wire heats the water injected into the insulation blanket, preventing the sprayed water temperature from affecting the concrete's insulation.
[0035] A water pump is installed inside the water replenishment tank 10, which pumps the water in the water replenishment tank 10 to the water supply channel of the insulation blanket.
[0036] One end of the blanket body 1 is provided with a connecting plug 13, and the other side of the blanket body 1 is provided with a connecting socket 12. The connecting plug 13 and the connecting socket 12 in the blanket body 1 are electrically connected through wires. Two adjacent blanket bodies 1 are connected by a direct connection between the connecting plug 13 and the connecting socket 12. The power supply lines of the heating cable 38 and the electromagnet 28 are integrated into the plug-in system composed of the connecting plug 13 and the connecting socket 12. The power supply lines of the heating cable 38 and the electromagnet 28 are provided with dual-channel relay modules to realize independent on / off control. With this configuration, the control system of this application can control the on / off of the heating cable 38 and the electromagnet 28 through the dual-channel relay modules.
[0037] Unused connectors 13 and 12 can be sealed by the second sealing cover 34, and both connectors 13 and 12 are waterproof.
[0038] The inner wall of the insulation layer 19 is provided with a reflective coating, which reflects heat and improves the insulation performance of the insulation blanket. The materials of the insulation layer 19 and the airtight surface layer 20 can be selected according to requirements and are not limited here. With the setting of the airtight surface layer 20, this application can reduce heat and humidity loss during use, utilize the heat and moisture retention of concrete, and at the same time, reduce oxygen entry to a certain extent, reduce the risk of fire inside the blanket, and improve the safety of the insulation blanket during use.
[0039] This invention also proposes a concrete intelligent thermal insulation control system, which is applied in a concrete intelligent thermal insulation device. The system includes a data acquisition module, a data processing and analysis module, and an execution module. The data acquisition module uses multi-source sensors to collect real-time temperature and humidity data of the concrete, temperature data of the surrounding environment of the concrete, and temperature data of the water in the water tank, and uploads the collected data to the data processing and analysis module. The first temperature sensor 5, humidity sensor 21, second temperature sensor 22, and third temperature sensor 36 together constitute the data acquisition module.
[0040] The data collected by the data acquisition module is transmitted to the data processing and analysis module via wireless communication and other means. Based on the collected ambient temperature data around the concrete, the data processing and analysis module selects a preset concrete curing mode, determines the temperature and humidity required for the concrete under this curing mode, and determines whether the water in the water tank needs to be heated. The data processing and analysis module compares the concrete temperature and humidity data collected by the data acquisition module with the temperature and humidity data required under the specific curing mode to determine whether the concrete needs to be kept warm and moist, and issues corresponding control commands.
[0041] The execution module consists of a dual-channel relay module, a heating module, a heating wire, and a water pump. The execution module receives commands via wireless communication and precisely executes concrete insulation and moisture retention operations, as well as heating operations in the water supply tank, achieving remote, intelligent, and automated control of the curing process and improving the curing effect of concrete in cold weather.
[0042] In summary, when using this intelligent concrete insulation device and control system, the user lays the insulation blanket on top of the concrete to be oxidized, connects the hollow bag 3 to the insulation blanket, and injects anti-freezing liquid into the hollow bag 3 to fix the position of the insulation blanket. The first temperature sensor 5 detects the ambient temperature, and the third temperature sensor 36 detects the temperature of the water in the water supply tank 10. Based on the detection results, when the water temperature is lower than a set threshold, the control system uses the heating module to heat the water in the water supply tank 10 to prevent the water in the water supply tank 10 from freezing. Based on the ambient temperature, the control system can select a preset concrete curing mode to ensure that the concrete can be well cured under various environmental conditions. When the concrete needs insulation, the control system activates the dual-channel relay module on the power supply line of the heating cable 38, energizing the heating cable 38. The heat emitted by the energized heating cable 38 insulates the concrete, and the second temperature sensor 22 monitors the concrete temperature in real time to ensure it remains within the optimal temperature range under the current curing mode, thus ensuring sufficient hydration and achieving the required structural performance. When the concrete needs moisture retention, the control system activates the water pump, pumping water from the water tank 10 to the spray hose 23 within the insulation blanket. The water is then sprayed onto the isolation layer 16 through the drain hole 32. The sprayed water is then applied to the concrete through micro-permeable holes in the isolation layer 16, achieving moisture retention. During the spraying process, the humidity sensor 21 monitors the concrete humidity in real time to ensure it remains within the optimal humidity range under the current curing mode, thus ensuring sufficient hydration and achieving the required structural performance.
