Technical Field
[0001] This invention relates to the field of steam curing technology for cement poles, and more particularly to a constant temperature and humidity energy-saving curing device for cement poles based on solar heating. Background Technology
[0002] The core of steam curing for cement pillars (i.e., cement poles) is completely consistent with the previously discussed process for cement poles. For long, mostly hollow cylindrical components like cement pillars, the selection of curing methods and automated control are particularly important in addition to the general process. Existing steam curing equipment can quickly generate a large amount of air through high-temperature heating, but since the water source for heating is usually room temperature water, heating it to a high temperature requires a lot of energy. Furthermore, the curing equipment lacks detection equipment and cannot adjust the temperature and humidity in real time, resulting in a low level of intelligence. Therefore, the present invention improves the existing equipment to address the above problems. Summary of the Invention

The solar power start / stop decision module determines the weather type based on the weather forecast and retrieves the power generation and consumption patterns under the same weather type from historical data. By comparing the power generation and consumption of each time period, the daytime is divided into two periods: "power accumulation" and "power consumption". Combining historical data and the energy demand of the day, a key "shortest qualified energy storage time" threshold is calculated, and the solar power mode is activated based on the threshold. The return water temperature control module calculates the heat lost by the hot water during the return process. When the high-temperature return water is about to enter the heat preservation tank, the system compares the temperature and volume of the return water with the water in the tank. If the return water temperature is higher and the volume is larger, the water in the tank is heated to the return water temperature first, and then the two are mixed to prevent the high-temperature water from being cooled down and wasting heat energy. Otherwise, they are mixed directly.

With power consumption ,Will The time periods marked are energy storage periods, and the rest are energy consumption periods; M2: Calculates the cumulative duration of the energy storage period under this weather condition. And its average value was calculated based on historical meteorological data of the same type. with standard deviation The first threshold is obtained. The second threshold is calculated based on the average daily required electricity consumption and the average net power generation during the energy storage period. Combined with the minimum continuous energy storage duration required by the system. Through weighting coefficients Calculate the final threshold ; M3: If the predicted energy storage period length under current meteorological conditions is greater than or equal to Then, the solar energy equipment will be turned on and off during the energy storage period.
[0006] Preferably, the data analysis steps of the reflux water temperature control module are as follows: N1: Collect ambient temperature and hot water return pipe inlet and outlet temperatures, perform data preprocessing to remove outliers; calculate pipe heat dissipation. Simultaneously calculate the heat loss of the water flow. ;verify And calculate the return water temperature ; N2: Obtain the water temperature inside the insulation tank With water volume ,like And return water volume and The difference exceeds the set threshold First, heat the water in the tank to... Then mix with the return water; otherwise, mix directly.
[0007] Preferably, the maintenance component includes a cover that is horizontally slidably mounted and fixed to the top surface of the maintenance chamber, and multiple temperature and humidity sensors are mounted and fixed around the cover.
[0008] Preferably, an installation frame is fixedly installed on the front and rear end faces inside the curing chamber, and multiple cement columns are horizontally mounted on the installation frame.
[0009] Preferably, the gas distribution assembly includes a water pump installed and fixed inside the bottom surface of the steam engine casing, and the output end of the water pump is connected to a heating chamber.
[0010] Preferably, a separation chamber is installed and fixed on the top surface of the heating chamber, and an air inlet pipe is connected to the top surface of the separation chamber, with the other end of the air inlet pipe connected to the interior of the curing chamber.
[0011] Preferably, the input end of the water pump is connected to a hot water inlet pipe, the other end of the hot water inlet pipe is connected to a heat preservation tank, the heat preservation tank is installed and fixed on the solar rack, multiple solar heating tubes are installed and fixed on the inclined surface of the solar rack, the input end of the heat preservation tank is connected to a hot water return pipe, and the other end of the hot water return pipe is connected to the lower part of the separation chamber.
[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. By combining the curing components and the gas distribution components, the device can utilize solar radiation to heat the steam water source, thereby reducing the energy consumption of water source heating and improving the energy efficiency of the device. At the same time, the temperature and humidity sensors can detect and control the curing temperature and humidity in real time, which improves the intelligence of the device and realizes the intelligent energy-saving capability of the device. Ultimately, it solves the problems of low intelligence and high energy consumption of existing equipment. 2. The solar energy start-stop decision module performs refined analysis based on weather forecasts and historical data, dynamically divides the "energy storage period" and "energy consumption period", and intelligently determines whether to activate the solar energy mode based on a multi-threshold fusion mechanism. Through adaptive adjustment of weight coefficients, the system can gradually optimize the decision strategy during trial operation, so as to maximize the use of solar energy under different weather conditions and effectively avoid maintenance interruptions caused by insufficient power supply. 3. The return water temperature control module accurately calculates the heat loss of the pipeline and the return water temperature. Based on the temperature and volume difference between the return hot water and the water in the tank, it intelligently selects a strategy of heating first and then mixing or mixing directly. This effectively avoids the heat loss caused by the high-temperature return water directly mixing with the low-temperature water in the tank, reduces the energy consumption of secondary heating, and thus improves the overall thermal efficiency of the solar thermal utilization system.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0016] Example 1: See Figures 1 to 4 The present invention discloses a constant temperature and humidity energy-saving maintenance device for cement poles based on solar heating, comprising a maintenance chamber 1 installed and fixed on the ground, a maintenance component on the maintenance chamber 1, a steam engine shell 3 on one side of the maintenance component, and an air distribution component inside the steam engine shell 3; the maintenance component includes a cover 2 horizontally slidably installed and fixed on the top surface of the maintenance chamber 1, multiple temperature and humidity sensors 8 are installed and fixed around the cover 2, and mounting frames 6 are installed and fixed on the front and rear end faces inside the maintenance chamber 1, with multiple cement columns 7 horizontally mounted on the mounting frames 6.
[0017] In this invention, to address the problems of low intelligence and high energy consumption in existing equipment, the following technical solution is adopted: The gas distribution component includes a water pump 10 installed and fixed inside the bottom surface of the steam engine casing 3. The output end of the water pump 10 is connected to a heating chamber 11. A separation chamber 12 is installed and fixedly connected to the top surface of the heating chamber 11. An air inlet pipe 13 is connected to the top surface of the separation chamber 12. The other end of the air inlet pipe 13 is connected to the interior of the curing chamber 1. The input end of the water pump 10 is connected to a hot water inlet pipe 9. The other end of the hot water inlet pipe 9 is connected to a heat preservation tank 4. The heat preservation tank 4 is installed and fixedly mounted on a solar rack 5. The solar rack 5 is installed and fixed outdoors. Multiple solar heating tubes 15 are installed and fixedly mounted on the inclined surface of the solar rack 5. The input end of the heat preservation tank 4 is connected to a hot water return pipe 14. The other end of the hot water return pipe 14 is connected to the lower part of the interior of the separation chamber 12. Through the cooperation of the curing component and the gas distribution component, the device can utilize solar radiation to heat the steam water source, thereby reducing the heating energy consumption of the water source and improving the energy efficiency of the device. At the same time, the temperature and humidity sensor 8 is used to detect and control the curing temperature and humidity in real time, improving the intelligence of the device.
[0018] Working Principle: In the use of this invention, firstly, power is supplied to the entire equipment to ensure the normal operation of each component. Then, the cement column 7 to be cured is stably installed on the mounting frame 6 fixed to the front and rear ends inside the curing chamber 1 using a hoisting method. After loading the cement column 7, the cover 2, horizontally slidable on the top surface of the curing chamber 1, is slid open to a closed state, forming a sealed curing space within the curing chamber 1. Next, the water pump 10, installed and fixed inside the bottom surface of the steam engine casing 3, and the heating chamber 11 connected to the output end of the water pump 10 are started. The water pump 10 draws pre-stored hot water from the insulated tank 4, installed and fixed on the solar rack 5, into the heating chamber 11 through the hot water inlet pipe 9 connected to its input end. The hot water is heated by the heating chamber 11 to generate a high-temperature water-gas mixture. This mixture then enters the separation chamber 12, which is connected and fixed to the top surface of the heating chamber 11. After separation and processing by the separation chamber 12, dry steam is obtained. The dry steam is transported to the inside of the curing chamber 1 through the air inlet pipe 13 connected to the top surface of the separation chamber 12, thus achieving curing of the cement column 7. Steam curing of cement column 7 on frame 6; during this process, the high-temperature water separated in separation chamber 12 will flow back to the heat preservation tank 4 through the hot water return pipe 14 connected to the lower part of its interior. The water in the heat preservation tank 4 will circulate in multiple solar heating tubes 15 fixed on the inclined surface of solar frame 5 under the action of hot fluid self-circulation, and achieve heating with the help of outdoor solar radiation. This cycle can make full use of solar energy resources and effectively reduce equipment energy consumption. During the entire curing stage, multiple temperature and humidity sensors 8 fixed around the cover 2 will collect temperature and humidity data in the curing chamber 1 in real time, and automatically adjust the steam supply and heating temperature of heating chamber 11 according to the collected data to ensure that the curing chamber 1 always maintains a constant temperature and humidity environment that meets the curing requirements of cement column 7. After the cement column 7 has completed curing, the water pump 10, heating chamber 11 and other related equipment are turned off, the power supply is disconnected, and then the cover 2 is slid open to lift and remove the cured cement column 7 from the mounting frame 6, completing the entire curing operation process.
[0019] Example 2: See Figure 5 The controller of the maintenance equipment is equipped with a solar-powered start / stop decision module and a return water temperature control module. The solar power start / stop decision module determines the weather type based on the weather forecast and retrieves the power generation and consumption patterns under the same weather type from historical data. By comparing the power generation and consumption of each time period, the daytime is divided into two periods: "can store electricity" and "will consume electricity". Combining historical data and the energy demand of the day, a key "shortest qualified energy storage time" threshold is calculated, and the solar power mode is activated based on the threshold. The return water temperature control module calculates the heat lost by the hot water during the return process. When the high-temperature return water is about to enter the heat preservation tank, the system compares the temperature and volume of the return water with the water in the tank. If the return water temperature is higher and the volume is larger, the water in the tank is heated to the return water temperature first, and then the two are mixed to prevent the high-temperature water from being "cooled down" and wasting heat energy. Otherwise, they are mixed directly. Based on weather forecasts, meteorological conditions were obtained, and the solar radiation intensity under corresponding historical conditions was acquired. The period from 6:00 AM to 6:00 PM was divided into three equal time periods, and each time period was further divided into four sub-periods. The power generation per unit time within each sub-period was then calculated. The calculation; based on historical data, the power consumption per unit time during the maintenance process. To acquire, to The time periods are marked as power consumption periods; The time period is marked as the energy storage time period; Historical power generation and power consumption data are marked with timestamps and then categorized according to meteorological conditions. The length of the energy storage period under the corresponding meteorological conditions is obtained. If the length of the energy storage period is less than the preset time length threshold (the time length of a single maintenance), it is determined that the meteorological conditions are not suitable for solar energy-saving operations, and the meteorological conditions are marked. For unmarked meteorological conditions, the start and stop points of the energy storage period are obtained. Under the corresponding meteorological conditions, the solar equipment starts working when the start point is reached and stops working when the stop point is reached. Obtain the cumulative duration of the energy storage period within a day under the corresponding weather conditions. Retrieve historical data within a specified time period from the current time point. Data, and perform mean of data and standard deviation The calculation sets a preset time length threshold. , For safety factor; Obtain the total stored electricity within a day under the corresponding weather conditions. Calculate the difference between total power generation and total power consumption data. If the difference is positive, the average daily required power consumption is calculated. The value equals the difference (daily required electricity consumption refers to the amount supplemented by the grid or energy storage); if it is negative, it is the daily required electricity consumption. Equal to zero; average net power generation during the energy storage period Then the preset time length threshold ; Based on historical data analysis, the minimum continuous energy storage time required to activate the solar power mode is determined. Taking all the above factors into account, a preset time length threshold is set. , These are the weighting coefficients; Initial settings During trial operation, if there are many power supply abnormalities after a set period of time, increase... If solar energy utilization is low, reduce Until The value is stable, and the stability under the corresponding meteorological conditions is recorded. The value is used under the corresponding meteorological conditions.
