Description

Technical Field

[0001] The present invention relates to the technical field of concrete curing, and particularly relates to a concrete curing device at a construction site. Background Art

[0002] With the increasing construction demand, concrete plays an increasingly important role in the construction industry. During the use of concrete, in order to ensure that the concrete can achieve the expected strength, durability and overall performance, it is necessary to cure the concrete. During the concrete curing process, it is necessary to analyze the environment to optimize the curing effect. For example, compared with the concrete curing at non-construction sites, the environment where the concrete is located at the construction site is more complex. Especially, the dust at the construction site is more serious than that at non-construction sites. During the concrete curing process, the dust covering the concrete surface will prevent the full penetration of water, resulting in too fast surface drying, affecting the strength and durability, and the fine particles in the dust adhering to the concrete surface, forming a pollution layer, affecting the subsequent painting and the adhesion of the protective layer.

[0003] The existing concrete curing devices generally use spraying equipment to spray the formed concrete at fixed times and fixed points. This curing method can achieve good results for concrete without dust influence. However, for the concrete at the construction site, it is easy to generate dust and make the dust adhere to the concrete surface to form a pollution layer and an isolation layer, thereby reducing the curing effect of the concrete, and easily causing insufficient overall construction efficiency and waste of resources.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs.

[0046] The following specifically describes the specific scheme of a concrete curing device at the construction site provided by the present invention in conjunction with the accompanying drawings.

[0047] An embodiment of a concrete curing device at the construction site:

[0048] Please refer to Figure 1 , which shows a concrete curing device at the construction site provided by an embodiment of the present invention. The concrete curing device at the construction site in this embodiment is as shown in Figure 1 and Figure 2 . In the figure: 22 is the first dust sensor; 23 is the second dust sensor; 41 is the spray port; 42 is the dust removal motor; 44 is the air supply device, and 45 is the air supply port. The concrete curing device at the construction site in this embodiment includes a first dust sensor 22, a second dust sensor 23, a spray port 41, a dust removal motor 42, a dust removal port 43, an air supply device 44, an air supply port 45, an information collection module, a data calculation module, and an instruction execution module.

[0049] The information collection module is used to respectively obtain the first dust concentration and the second dust concentration in the environment where the concrete is located at the construction site during the current time period by using the first dust sensor 22 and the second dust sensor 23.

[0050] The data calculation module is used to obtain the first type of dust growth index for each moment according to the change situation of the first dust concentration at all moments before each moment during the current time period; combine the time interval between each moment and the next concrete curing during the current time period, the second dust concentration at each moment, and the first type of dust growth index to obtain the influence parameter of the second type of dust on concrete curing for each moment.

[0051] An instruction execution module, configured to adjust the operating power of the dust removal motor 42 and the air supply device 44 based on the difference between the second dust concentration at each moment and the current moment within the current time period; and adjust the water output of the spray nozzle 41 based on the difference between the influence parameter of the second type of dust on concrete curing at each moment and the current moment within the current time period.

[0052] The concrete curing equipment for the construction site provided in this embodiment is to effectively cure the concrete in the construction site environment and avoid the negative impact of the dust at the construction site on the concrete curing effect. Therefore, the main logic is as follows: The information acquisition module is used to collect the dust concentration data around the concrete to be cured at the construction site. Then, the data calculation module analyzes the influence state of the dust concentration data on concrete curing. Furthermore, the dust treatment system and the concrete curing system in the instruction execution module are used for concrete curing under the dust condition.

[0053] First, the information acquisition module of the concrete curing equipment for the construction site is used to collect the dust concentration data around the concrete to be cured at the construction site. The specific process is as follows: The influence of dust on concrete curing is mainly divided into two aspects. The first aspect is the direct influence item, that is, the dust covering the concrete surface, which will absorb part of the water and pollute the concrete surface during concrete curing. The second aspect is the airborne dust. This type of dust floats in the air and will eventually land on the ground due to gravity. Part of it will land on the concrete surface, forming pollution during curing. Therefore, in this embodiment, these two types of dust are detected separately to obtain two types of environmental dust concentration data. The acquisition method of the first type of environmental dust concentration data is: Use the first dust sensor 22 to detect the dust concentration in the environment where the concrete is located at the construction site to obtain the first dust concentration. The acquisition method of the second type of environmental dust concentration data is: Start the air supply device 44 in the instruction execution module to make the device generate wind and blow along the air outlet towards the concrete surface to stir up the deposited dust on the concrete surface. Then, use the second dust sensor 23 of the information acquisition module to detect the concentration of the deposited dust on the concrete surface stirred up by the air supply device 44 to obtain the second dust concentration. In this embodiment, the acquisition frequency of the first dust concentration and the second dust concentration is set to once per second, that is, a first dust concentration and a second dust concentration are collected every second. In specific applications, the implementer can set the acquisition frequency according to the specific situation. This embodiment uses the first dust sensor 22 and the second dust sensor 23 to collect the first dust concentration and the second dust concentration in the environment where the concrete is located at the construction site at each acquisition moment within the current time period. The current time period is a set of all historical moments whose time interval from the current moment is less than or equal to the preset duration. In this embodiment, the preset duration is 20 minutes. In specific applications, the implementer can set it according to the specific situation. It should be noted that: All moments mentioned later are acquisition moments.

[0054] In this embodiment, the models of the first dust sensor 22 and the second dust sensor 23 are SDS026 industrial dust sensors, and the specific parameter information is shown in Table 1:

[0055] Table 1 Parameter information table of SDS026 industrial dust sensor

[0056]

[0057] The states of the influence of the two types of dust concentration data on concrete curing can be specifically divided into multiple situations. The first type of dust can be continuously converted into the second type of dust, and the direct impact of the second type of dust on concrete curing is as follows:

[0058] First, in the case where the first type of floating dust is less, the growth trend is slower, and the second type of deposited dust is more. For the first type of floating dust, use the conventional irrigation amount to cure the concrete, and then cover it with a covering material. Because the floating dust is less and the growth rate is slower, the amount of dust finally falling on the concrete surface before the next irrigation is less, and the water absorption of the cured concrete is smaller. Therefore, the first type of floating dust has a smaller impact on the final curing effect of the concrete. And the second type of deposited dust is more, and the impact on concrete curing is that there is less effective curing water. Therefore, a higher power is required to remove the dust on the concrete surface, and a larger irrigation amount should be given to avoid incomplete removal of the deposited dust.

[0059] Secondly, in the case where the first type of floating dust is more, the growth trend is faster, and the second type of deposited dust is more. A large amount of the first type of floating dust will fall onto the concrete surface and be converted into more second type of deposited dust. Therefore, a larger irrigation amount and a higher dust removal power are required to remove the deposited dust on the concrete surface, and the wetness of the concrete surface should be maintained for a long time to avoid the dust falling after curing from affecting the curing effect.

[0060] Then, in the case where the first type of floating dust is less, the growth trend is not fast, and the second type of deposited dust is less. The conversion speed of the first type of dust to the second type of dust is insufficient, and the second type of deposited dust on the concrete surface is less. Therefore, it is sufficient to cure the concrete with the conventional irrigation amount and dust removal power.

[0061] Finally, in the case where the first type of floating dust is more, the growth trend is faster, and the second type of deposited dust is less. The first type of dust has a sufficient conversion speed to the second type of dust. Therefore, a larger irrigation amount is required to keep the concrete surface wet for a long time. Since the second type of deposited dust is less, it is sufficient to remove the dust on the concrete surface with the conventional dust removal power.

[0062] Based on the above features, the data calculation module evaluates the growth situation of the first type of dust according to the difference between the first dust concentration at each moment and its adjacent moment within the current time period.

[0063] Specifically, the average value of the first dust concentration at each moment and its adjacent moment within the current time period is used as the first average value corresponding to that moment, that is, each moment within the current time period corresponds to a first average value. Next, taking a moment within the current time period as an example for illustration, the method provided in this embodiment can be used to process other moments within the current time period. Denote any moment within the current time period as the candidate moment. According to the overall difference between the first average values of all moments before the candidate moment and the first dust concentration of the candidate moment within the current time period, the first type of dust growth index of the candidate moment is obtained. Specifically, calculate the difference between the first average value of each moment before the candidate moment and the first dust concentration of the candidate moment within the current time period, and denote it as the first difference between each moment before the candidate moment and the candidate moment within the current time period; the average value of the first differences between all moments before the candidate moment and the candidate moment within the current time period is determined as the first type of dust growth index of the candidate moment.

[0064] In this embodiment, a specific calculation formula for the first type of dust growth index is given. The first type of dust growth index at the t-th moment within the current time period can be expressed as:

[0065]

[0066] Where, represents the first type of dust growth index at the t-th moment within the current time period, represents the first dust concentration at the -th moment before the t-th moment within the current time period, represents the first dust concentration at the -th moment before the t-th moment within the current time period, represents the first dust concentration at the +1-th moment before the t-th moment within the current time period, represents the first dust concentration at the t-th moment within the current time period.

[0067] represents the first average value at the -th moment before the t-th moment within the current time period, represents the first difference between the -th moment before the t-th moment and the t-th moment within the current time period, is used to characterize the overall difference between the first average values of all moments before the t-th moment and the first dust concentration of the t-th moment within the current time period.

[0068] Since the impact of the first type of dust on concrete curing has a lag, specifically manifested as the continuous dust in the current environment partially landing on the surface of the concrete to form the second type of dust, the impact of the dust amount at the t-th moment in the current time period on concrete curing is only a start, and it is necessary to consider the change of the first type of dust amount after the t-th moment. Therefore, the data calculation module uses the first dust concentration in the historical moments before the t-th moment to simply predict the change trend of the concentration data of the first type of dust after the -th moment, so as to obtain the growth trend of the first type of dust concentration after the

[0069] -th moment, which is recorded as the first type of dust growth index at the t-th moment.

[0070] The impact of the first type of dust on concrete curing is indirectly continuous. Therefore, judge the interval between the current curing time and the next curing time. The longer the current curing time is from the next curing time, the greater the first dust concentration at the current moment, and the more obvious the continuous growth trend is. Then, the more the first type of dust is converted into the second type of dust after this curing of the concrete, and the more serious the impact on this curing is.

[0071] Next, according to the first dust concentration at the candidate moment, the first type of dust growth index at the candidate moment, and the time interval between the candidate moment and the next concrete curing, the influence parameter of the first type of dust on concrete curing at the candidate moment is obtained; specifically, the negative correlation normalization result of the first type of dust growth index at the candidate moment is obtained; according to the first dust concentration at the candidate moment, the time interval between the candidate moment and the next concrete curing, and the negative correlation normalization result, the influence parameter of the first type of dust on concrete curing at the candidate moment is obtained, and both the first dust concentration and the time interval are positively correlated with the influence parameter of the first type of dust on concrete curing at the candidate moment, and the negative correlation normalization result is negatively correlated with the influence parameter of the first type of dust on concrete curing at the candidate moment.

[0072] According to the first eigenvalue corresponding to the candidate moment and the influence parameter of the first type of dust on concrete curing at the candidate moment, the influence parameter of the second type of dust on concrete curing at the candidate moment is obtained, and both the first eigenvalue and the influence parameter of the first type of dust on concrete curing are positively correlated with the influence parameter of the second type of dust on concrete curing. The first eigenvalue corresponding to the candidate moment is the ratio between the second dust concentration at the candidate moment and the average value of the second dust concentrations at all moments within the current time period.

[0073] Among them, the positive correlation relationship means that the dependent variable increases as the independent variable increases and decreases as the independent variable decreases, and it can be an additive relationship, a multiplicative relationship, etc., which is determined by the actual application; the negative correlation relationship means that the dependent variable decreases as the independent variable increases and increases as the independent variable decreases, and it can be a subtractive relationship, a divisive relationship, etc.

[0074] In this embodiment, specific calculation formulas for the influence parameter of the first type of dust on concrete curing and the influence parameter of the second type of dust on concrete curing are given. The influence parameter of the first type of dust on concrete curing and the influence parameter of the second type of dust on concrete curing at the t-th moment within the current time period can be expressed as:

[0075]

[0076]

[0077] Among them, represents the influence parameter of the first type of dust on concrete curing at the t-th moment within the current time period, represents the first dust concentration at the t-th moment within the current time period, represents the first type of dust growth index at the t-th moment within the current time period, represents the current moment, represents the serial number of the moment within the current time period, The symbol "|" represents the absolute value symbol, and T represents the number of moments within the current time period. represents the second dust concentration at the t-th moment within the current time period. represents the influence parameter of the second type of dust on concrete curing at the t-th moment within the current time period, and e represents the natural constant.

[0078] represents the negative correlation normalization result of the first type of dust growth index at the t-th moment within the current time period. When calculating the influence parameter of the second type of dust on concrete curing, not only the size of the second type of dust data itself needs to be considered, but also the conversion situation of the first type of dust into the second type of dust needs to be considered. Therefore, in this embodiment, the influence parameter of the first type of dust on concrete curing is used as the adjustment value of the influence parameter of the second type of dust on concrete curing, and the relative size of the second type of dust at the t-th moment to the second type of dust at historical moments is used as the main body to obtain the influence parameter of the second type of dust on concrete curing. The larger this value is, the more covering dust there is on the concrete surface at the t-th moment, and there will be more dust covering the concrete surface at future moments.

[0079] Thus, the influence parameter of the second type of dust on concrete curing at each moment is obtained by using the method provided in this embodiment.

[0080] Finally, the execution parameters of different systems in the concrete curing instruction execution module are obtained according to the influence of dust on concrete curing.

[0081] The curing of concrete in the concrete curing equipment mainly uses the spray nozzle 41, dust removal motor 42, dust removal port 43, and air supply equipment 44 in the instruction execution module to achieve surface dust removal and surface spraying of concrete, which can be specifically divided into two aspects. The first aspect is the dust removal system, and the second aspect is the spraying system.

[0082] The purpose of the dust removal system is only to remove the dust on the current concrete surface. Therefore, only the second type of covering dust on the current concrete surface needs to be considered, and there is no need to consider the problem of the subsequent conversion of the first type of dust into the second type of dust. It is only necessary to compare the concentration data of the second type of dust with the data at historical moments.

[0083] The difference between the second dust concentration at the current moment and the second dust concentration at each moment within the current time period is denoted as the second difference between the current moment and each moment within the current time period; calculate the first normalization value of the average value of the second differences between the current moment and all moments within the current time period, and subtract the preset adjustment parameter from the first normalization value to obtain the power parameter. The power parameter can be expressed as:

[0084]

[0085] Wherein, W represents a power parameter, T represents the number of moments within the current time period, represents the second dust concentration at the t-th moment within the current time period, represents the second dust concentration at the current moment, is a preset adjustment parameter, represents a normalization function.

[0086] In this embodiment, the preset adjustment parameter is 0.5. In specific applications, the implementer can set it according to specific circumstances.

[0087] The greater the dust concentration at the t-th moment within the current time period, the stronger the power is required to handle the dust on the concrete surface corresponding to the current moment; represents the second difference between the current moment and the t-th moment within the current time period, represents the average value of the second differences between the current moment and all moments within the current time period, and the first normalization value of the average value of the second differences between the current moment and all moments within the current time period. When the first normalization value is greater, stronger power is required to handle the dust on the concrete surface corresponding to the current moment, that is, the power parameter is greater.

[0088] After obtaining the power parameter, take the product of the power parameter and the operating power of the dust removal motor 42 at the current moment as the new operating power of the dust removal motor 42; take the product of the power parameter and the operating power of the air supply device 44 at the current moment as the new operating power of the air supply device 44.

[0089] The purpose of the spraying system is to keep the concrete continuously moist before the next spraying. Therefore, it is necessary to consider the covering dust at the current moment and the influence of the subsequent conversion of the first type of dust into the second type of dust on the subsequent concrete surface. Therefore, the influence parameter of the second type of dust on concrete curing is used for calculation.

[0090] Specifically, record the difference between the influence parameter of the second type of dust on concrete curing at the current moment and the influence parameter of the second type of dust on concrete curing at each moment within the current time period as the third difference between the current moment and each moment within the current time period; calculate the second normalization value of the average value of the third differences between the current moment and all moments within the current time period, and subtract the preset adjustment parameter from the second normalization value to obtain the water output parameter. The water output parameter can be expressed as:

[0091]

[0092] Wherein, S represents the water output parameter, represents the influence parameter of the first type of dust on concrete curing at the current moment.

[0093] represents the third difference between the current moment and the t-th moment within the current time period, represents the average value of the third differences between the current moment and all moments within the current time period, represents the second normalization value of the average value of the third differences between the current moment and all moments within the current time period. When the second normalization value is larger, the water output parameter is larger.

[0094] After obtaining the water output parameter, the product of the water output parameter and the water output of the spray nozzle 41 at the current moment is used as the new water output of the spray nozzle 41. As Figure 3 shown, this figure is a schematic diagram of the data processing flow corresponding to the concrete curing equipment at the construction site.

[0095] So far, the new operating power of the dust removal motor 42, the new operating power of the air supply device 44, and the new water output of the spray nozzle 41 have been obtained by using the above method. The instruction execution module adjusts them. The air supply device 44 operates at the new operating power to stir up the dust on the concrete surface; then the dust removal motor 42 absorbs the stirred-up dust through the dust removal port 43 at the new operating power, and the spray nozzle 41 sprays the concrete with the new water output.

[0096] The concrete curing equipment at the construction site provided in this embodiment includes a first dust sensor 22, a second dust sensor 23, a spray nozzle 41, a dust removal motor 42, a ventilation device 44, an information collection module, a data calculation module, and an instruction execution module. The information collection module collects the first dust concentration and the second dust concentration in the environment where the concrete is located at the construction site during the current time period. The first dust concentration is used to reflect the concentration of dust in the air, and the second dust concentration is used to reflect the concentration of dust covering the concrete surface. Since the impact of the first type of dust on the curing of concrete has a lag, specifically manifested as the continuous dust in the current environment partially lands on the concrete surface and then forms the second type of dust. The data calculation module simply predicts the change trend of the concentration data of the first type of dust based on the change situation of the first dust concentration at all previous moments during the current time period, and obtains the growth index of the first type of dust, which is used to reflect the growth trend of the first dust concentration. Then, by combining the time interval between each moment and the next concrete curing during the current time period, the second dust concentration at each moment, and the growth index of the first type of dust, the influence parameter of the second type of dust on the concrete curing at each moment is obtained. The instruction execution module adjusts the operating power of the dust removal motor 42 and the ventilation device 44 based on the difference in the second dust concentration between each moment and the current moment during the current time period, and adjusts the water output of the spray nozzle 41 based on the difference in the influence parameter of the second type of dust on the concrete curing between each moment and the current moment during the current time period, thereby completing the curing work of the concrete, improving the curing effect of the concrete, and avoiding waste of resources.

[0097] It should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the principles of the present invention shall be included within the protection scope of the present invention.
