Description

Technical Field

[0001] This utility model relates to the field of wind turbine foundation concrete technology, specifically a closed-loop dual-control intelligent curing device for wind turbine foundation concrete. Background Technology

[0002] For the curing of large-volume concrete, the temperature difference between the inside and outside must be strictly controlled to not exceed 25℃. Current industry solutions include two types: one is a wireless temperature measurement system based on pre-embedded sensors to collect temperature data and issue alarms for exceeding limits; the other is manual curing, which regulates the temperature by sprinkling water or covering with insulation materials.

[0003] Currently, wind power foundation temperature monitoring devices use distributed temperature sensor networks and multi-level alarm mechanisms, but they do not integrate automatic handling functions for temperature anomalies. Maintenance actions rely entirely on manual execution, and the average time from temperature alarm to manual intervention is 120 minutes. This makes it impossible to suppress sudden temperature changes in time, and manual operation makes it difficult to ensure uniformity of maintenance. The temperature difference on the foundation surface can reach up to ±5℃. Manual maintenance in low-temperature environments (especially below -10℃) poses safety risks and is inefficient.

[0004] Based on this, this utility model proposes a closed-loop dual-control intelligent curing device for wind turbine foundation concrete. Utility Model Content

[0005] To address the aforementioned technical issues, this utility model proposes a closed-loop dual-control intelligent curing device for wind turbine foundation concrete. This device can construct an automatic closed-loop system for handling abnormal temperatures, compressing the response delay to within 3 minutes. Through the coordinated operation of a ring-shaped drip irrigation and heating unit, it achieves precise control of surface temperature difference ≤ ±1.5℃, reducing the frequency of manual intervention by more than 80% and improving adaptability to extreme working conditions.

[0006] The technical solution to achieve the purpose of this utility model is: a closed-loop dual-control intelligent curing device for wind turbine foundation concrete, comprising:

[0007] A ring-shaped layout unit, comprising drip irrigation tape and electric heating tape, wherein the drip irrigation tape and electric heating tape are laid parallel to each other on the base surface;

[0008] The sensing unit includes a temperature sensor group, which is embedded in the foundation and on its surface.

[0009] The execution unit includes a drip irrigation system and an electric heat tracing system, wherein the drip irrigation tape is connected to the external drip irrigation system and the electric heat tracing tape is connected to the external electric heat tracing system;

[0010] The control unit includes a central controller, which receives monitoring data from the temperature sensor group and drives the drip irrigation system or electric heat tracing system to start and stop based on a preset temperature difference threshold.

[0011] Preferably, the drip irrigation system includes a water pump, a solenoid valve, and a water supply network, and the electric heat tracing system includes a temperature control distribution cabinet and an armored heat tracing cable.

[0012] Preferably, the control unit has a built-in anti-false triggering module, which only triggers the execution unit to act when the temperature change rate continuously exceeds a set threshold.

[0013] Preferably, the execution unit is locked for a preset time after it is activated to prevent the drip irrigation system and electric heat tracing system from starting and stopping frequently.

[0014] Preferably, the drip irrigation tape and the electric heating tape are arranged in concentric circles and maintain a fixed spacing to cover the base surface without any blind spots.

[0015] Preferably, the temperature sensor group is a PT100 type sensor, and its signal output terminal is interlocked with the central controller.

[0016] Compared with existing technologies, the significant advantages of this invention are:

[0017] Firstly, by constructing a closed-loop dual-control intelligent maintenance system, the maintenance efficiency of wind turbine foundation concrete has been significantly improved. In terms of temperature control response, the system greatly reduces the delay time for handling abnormal temperatures, effectively inhibiting the formation of temperature stress cracks in concrete.

[0018] Secondly, this utility model adopts a structural design in which drip irrigation tape and electric heating tape are laid in a parallel ring, which reduces the temperature difference on the base surface from ±5℃ in traditional manual operation to ±1.5℃, completely avoiding the generation of local micro-cracks. The electric heating system has an IP68 protection rating and can operate stably in extreme low temperature environments of -30℃, significantly improving the adaptability to harsh working conditions such as high humidity and low temperature. The precise spraying of the drip irrigation system saves 38% more water than manual watering, realizing efficient use of resources. Attached Figure Description

[0025] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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 protection scope of the present invention.

[0026] This utility model provides an improved closed-loop dual-control intelligent curing device for wind turbine foundation concrete. The technical solution of this utility model is as follows:

[0027] like Figures 1-3 As shown, a closed-loop dual-control intelligent curing device for wind turbine foundation concrete includes:

[0028] The ring-shaped layout unit includes drip irrigation tape 101 and electric heating tape 102, both of which are laid parallel to the base surface.

[0029] The sensing unit includes a temperature sensor group 103, which is embedded in the foundation and on its surface.

[0030] The execution unit includes a drip irrigation system 104 and an electric heat tracing system 105. The drip irrigation tape 101 is connected to the external drip irrigation system 104, and the electric heat tracing tape 102 is connected to the external electric heat tracing system 105.

[0031] The control unit includes a central controller 106, which receives monitoring data from the temperature sensor group 103 and drives the drip irrigation system 104 or the electric heat tracing system 105 to start and stop based on a preset temperature difference threshold. This device reduces the frequency of manual maintenance by more than 80% by intelligently replacing manual intervention, directly reducing labor costs and avoiding operational safety risks in extreme environments. It also greatly reduces the delay in handling abnormal temperatures and effectively inhibits the formation of temperature stress cracks in concrete.

[0032] Furthermore, such as Figure 3 As shown, the drip irrigation system 104 includes a water pump, a solenoid valve, and a water supply network. The water pump needs to meet the pressure requirements of large-area spraying. The electric heat tracing system 105 includes a temperature control distribution cabinet and an armored heat tracing cable. The temperature control distribution cabinet can be adapted to heat tracing cables of different power. The outer layer of the armored heat tracing cable is made of stainless steel woven mesh to resist mechanical damage and chemical corrosion.

[0033] Furthermore, such as Figure 2 and Figure 3 As shown, the control unit has a built-in anti-false triggering module. This module only triggers the execution unit to operate when the temperature change rate continuously exceeds a set threshold, thus preventing the execution unit from starting frequently.

[0034] Furthermore, such as Figure 2 As shown, after the execution unit performs an action, it is forcibly locked for a preset time to prevent the drip irrigation system 104 and the electric heating system 105 from starting and stopping frequently. After the action stops, it is locked for 10 minutes to protect the motor life and reduce energy consumption by 35%.

[0035] Furthermore, such as Figure 1 As shown, the drip irrigation tape 101 and the electric heating tape 102 are arranged in concentric circles and maintain a fixed spacing to cover the base surface without dead corners. The drip irrigation tape (101) is made of ring-shaped flexible PVC material with a spacing of 10cm to achieve water-saving atomized spraying.

[0036] Furthermore, such as Figure 1 As shown, the temperature sensor group 103 is a PT100 type sensor, and its signal output terminal is interlocked with the central controller 106. The temperature sensor group 103 is used to synchronously monitor the temperature gradient between the core and the surface.

[0037] The specific working method is as follows: the temperature sensor group 103 monitors the temperature difference data inside and outside the foundation in real time and transmits it to the central controller 106; when the temperature difference exceeds the preset threshold, the controller judges the temperature status - if the external temperature is too high, the drip irrigation system 104 is started to spray and cool down; if the external temperature is too low, the electric heat tracing system 105 is activated to heat and keep warm; the execution continues until the temperature difference returns to the threshold range and stops automatically; then the system enters a forced lock state to prevent the execution unit from starting and stopping frequently; after the lock is released, it re-enters the monitoring cycle, forming a fully automatic closed-loop temperature control maintenance.

[0038] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
