Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically to a color matching device for adjusting the color difference of concrete. Background Technology

[0002] Uneven color variation is a common problem in the concrete surfaces of exposed equipment foundations, fair-faced concrete firewalls, converter transformer concrete plazas, and station perimeter walls within ultra-high-voltage converter stations. Sometimes spots and fine lines appear, and in severe cases, honeycomb-like pitting and cracks may occur, significantly impacting the appearance and quality of the concrete and the overall image of the converter station project. The causes of concrete color variation include impurities in raw materials such as cement, aggregates, water-cement ratio, and admixtures; the precipitation of calcium hydroxide during cement hydration, which readily reacts with carbon dioxide to form white calcium carbonate crystals; inadequate vibration during construction can create air bubbles and voids, leading to color variations; insufficient demolding time can cause cracks; and inadequate protection of finished products can result in concrete contamination and damage, also causing color variations.

[0003] To achieve color difference control during concrete repair, patent CN115324374A discloses a method for repairing concrete appearance defects. This method involves preparing repair agents of different colors, applying them to curing test blocks, and obtaining color cards of different colors after the repair agents have solidified and their colors no longer change. During repair, the different color cards are compared with the target color of the concrete structure, and the color card with the closest color is selected. Repair agents are then prepared based on the selected color card to repair the color difference areas. Existing color difference control methods can only repair areas to match the target color when the target color matches the prepared color card. However, the multiple possibilities of the target color for converter station concrete conflict with the limitations of preset color cards, making accurate color difference repair difficult and unfavorable for color difference repair on concrete surfaces.

[0004] In their patent "Control System and Method for Appearance Color Difference of Concrete in Converter Stations", the inventors' team provided a method for real-time acquisition of the color difference between the sample color of a color difference protectant sample and the target color of the target concrete. This method requires a color matching device that can conveniently and quickly extract a portion of the sample when preparing the color difference protectant sample. At present, such a matching color matching device is lacking. Summary of the Invention

[0005] One objective of this invention is to provide a color matching device for adjusting the color difference of concrete. This device is used to perform one or more samplings during the preparation of a color difference protection agent sample, in conjunction with a method for real-time acquisition of the color difference between the sample color and the target color.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A color matching device for adjusting the color difference of concrete includes a cylinder with a cover. The cover has a feeding port and a first motor. The output end of the first motor movably passes through the cover and is connected to a stirring paddle located inside the cylinder. The side wall of the cylinder also has a sampling port and a sampling valve assembly. The sampling valve assembly is used to install a sampling bottle and to open or close the sampling port.

[0008] In this technical solution, the cylinder is used to hold the color difference protectant sample, the first motor on the cover is used to drive the stirring paddle to rotate to stir the color difference protectant sample in the cylinder, and the feeding port on the cover is used to add the desired colorant, such as black colorant, into the cylinder to change the color of the color difference protectant sample.

[0009] In this technical solution, a sampling port is provided on the side wall of the cylinder, which connects the inner and outer sides of the cylinder. A sampling valve assembly is also provided on the cylinder, which has two states: open and closed. In the open state, the color difference protectant sample in the cylinder can enter the sampling bottle for collection through the sampling port and the sampling valve assembly. In the closed state, the sampling port is closed by the sampling valve assembly.

[0010] With the above settings, it is possible to take samples in real time as needed during the preparation of color difference protectant samples in the cylinder, so that staff can compare the color difference between the sample color of the color difference protectant sample and the required target color in real time, thereby improving the overall efficiency and accuracy of color difference protectant preparation and making the preparation process more controllable.

[0011] The sampling valve assembly can be installed on the side wall of the cylinder using an existing valve structure to open for sampling when needed. As a preferred structure of the sampling valve assembly in this invention, the assembly includes a slider with a through-hole for mounting the sampling bottle. The slider is movable along the outer wall of the cylinder to either an open or closed state. In the open state, the through-hole connects the sampling bottle and the sampling port; in the closed state, the slider blocks the sampling port.

[0012] In this technical solution, the connecting port on the slider of the sampling valve assembly penetrates the slider. The outer end face of the connecting port can be provided with an interface that matches the mouth of the sampling bottle, and the inner end face of the connecting port fits against the side wall of the cylinder or the sliding groove, thereby allowing the slider to move up and down along the side wall of the cylinder. When the slider moves to the point where the sampling port and the connecting port are connected, the sample prepared in the cylinder can be pressed into the sampling bottle for collection through the sampling port and the connecting port. Preferably, the sampling port is located near the bottom of the cylinder to allow some sample to be pressed into the sampling bottle for collection even when the sample liquid level in the cylinder is not high. After sampling is completed, the slider is moved to the point where the sampling port and the connecting port are not connected, and the sampling port is sealed by the inner wall surface of the slider.

[0013] With the above settings, the sampling valve assembly not only enables convenient and rapid real-time sampling during the preparation process, but also ensures that the sampling process does not significantly affect the stirring of the sample inside the cylinder, and the sample collected in the sampling bottle is more uniform. Moreover, the sample inside the cylinder is forced into the sampling bottle under liquid pressure until the sampling bottle is full of small samples, thus achieving basic consistency in the sampling amount each time without additional control, simplifying the overall preparation process, improving the accuracy of sampling, and facilitating further clarification of the sample composition ratio.

[0014] Furthermore, a groove is provided on the outer wall of the cylinder, and the slider is installed in the groove and can move up and down along the groove. In this technical solution, the groove is used to define the upper and lower limits of the slider's stroke, so that the upper or lower limit of the slider's stroke can be set to an open or closed state.

[0015] Furthermore, a guide groove is provided within the slide groove, and a guide rod is slidably disposed within the guide groove, the guide rod being fixedly connected to the slider. In this technical solution, the guide rod fixed on the slider can move along the guide groove, and the guide groove limits the movement of the guide rod, making the movement of the slider along the guide groove more reliable. In one or more embodiments, the guide rod can be made of metal, and a magnet can be provided at the bottom of the guide groove to position the guide rod within the guide groove when the end face of the guide rod approaches the guide groove, thereby fixing the slider in an open or closed state.

[0016] Furthermore, a spring is provided within the slide groove, and the spring is connected to the slider. When it is necessary to enter the open or closed state, the slider can be pushed to overcome the elastic force of the spring to switch states. When it is necessary to return to the closed or open state, the elastic force can be used to quickly switch states.

[0017] Furthermore, the cover is provided with an observation window. The observation window allows for real-time observation of the stirring process inside the cylinder, and a colorimeter can also be used to collect sample colors in real time through the observation window or an open observation window.

[0018] Another objective of this invention is to provide a color matching device for adjusting the color difference in concrete. This device can not only take samples in real time during the preparation of color difference protection agent samples, but also simultaneously prepare small-volume supplementary samples during the sample preparation process. This allows for the addition of supplementary samples with a volume and ratio basically consistent with the sampled sample to the cylinder after each sampling, thereby reducing the error in the final amplified preparation and improving the accuracy of color matching.

[0019] The objective of this utility model is achieved through the following technical solution:

[0020] A sample preparation device includes a cylindrical body with a cover. The cover has a feeding port and a first motor. The output end of the first motor movably passes through the cover and is connected to a stirring paddle located inside the cylindrical body. A groove is also provided on the side wall of the cylindrical body. The groove has a sampling port communicating with the interior of the cylindrical body and a slider that moves along the groove. The slider has a connection port passing through it for mounting a sampling bottle. The slider can move along the outer wall of the cylindrical body to an open or closed state. In the open state, the connection port connects the sampling bottle and the sampling port; in the closed state, the slider blocks the sampling port.

[0021] The supplementary equipment includes a base on which at least one station for installing a supplementary bottle is provided, the volume of the supplementary bottle being equal to the volume of the sampling bottle.

[0022] During the preparation of the color difference protectant sample inside the cylinder, multiple samplings are required as different colored toners are added. However, after each sampling, the total volume of the color difference protectant sample will decrease, and the volume ratio of each toner of the same volume added subsequently in the color difference protectant sample will increase. This results in a large error between the actual ratio of the final color difference protectant sample and the recorded volume of added toner. This error will be further amplified when preparing color difference protectant samples on a larger scale based on the color difference protectant sample, leading to inaccurate color difference protectant sample preparation.

[0023] To address this issue, this technical solution also includes supplementary equipment, which includes a base. One or more stations for installing supplementary bottles can be set on the base, depending on the estimated number of sampling attempts. The volume of the supplementary bottle must be equal to the volume of the sampling bottle.

[0024] In use, after adding the initial color difference protectant sample (e.g., 500 ml) to the cylinder, add an equal volume of the reduced color difference protectant sample (e.g., 50 ml) to the replenishment bottle. Subsequently, each time toner is added to the color difference protectant sample, the same volume ratio of toner is added to the replenishment bottle. For example, when adding 2 ml of black toner to the cylinder, 0.2 ml of black toner is added dropwise to the replenishment bottle. In this way, the color difference protectant sample in the replenishment bottle maintains a substantially consistent ratio with the color difference protectant sample in the cylinder, and the color difference protectant in the replenishment bottle does not require stirring.

[0025] After each sampling, a small sample of color difference protectant is poured into the cylinder to prevent significant changes in the ratio within the cylinder. This allows for a sufficiently large sample volume, reducing errors during sample preparation or color difference testing. Furthermore, it significantly reduces the discrepancy between the actual and recorded ratios of the final color difference protectant sample, resulting in a more consistent color with the desired target color when the color difference protectant sample is subsequently amplified from the original sample.

[0026] Furthermore, it also includes a color mixing bottle, the bottom of which is provided with at least one discharge port, and the interior of which is provided with a rotary valve for opening or closing the discharge port; a bracket is provided on the base, and a second motor is provided on the bracket, the output end of which is connected to a rotating rod, and the rotating rod is connected to each rotary valve.

[0027] In this technical solution, the bracket on the base is used to mount the second motor, which is preferably a servo motor. The second motor drives the rotating rod to rotate at a certain angle, which in turn causes each rotating valve on the rotating rod to rotate synchronously at a certain angle, such as 90 degrees. This allows all the outlets at the bottom of the same colorant bottle to open or close simultaneously, thereby adding the same volume of colorant to all replenishment bottles at the same time. This further improves the consistency between the sample ratio in the replenishment bottles and the sample ratio in the current cylinder, and simplifies the sample preparation process.

[0028] Furthermore, it also includes a feeding hopper, the inlet of which is connected to the outlet of the color bottle, and the outlet of which is connected to the refill bottle. The feeding hopper is a separate component, allowing for adjustments to the number and type of color bottles as needed. It also facilitates the easy installation and removal of refill bottles.

[0029] Furthermore, the volume of the replenishment bottle is 0.05 to 0.1 times the volume of the color difference protectant sample prepared in the cylinder. If the volume of the replenishment bottle is too large, it will result in a large sampling amount, exceeding the material requirements for subsequent color patch preparation, leading to material waste; if the volume of the replenishment bottle is too small, it is prone to producing large errors.

[0030] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0031] 1. This utility model enables real-time sampling as needed during the preparation of color difference protectant samples inside the cylinder, allowing staff to compare the color difference between the sample color and the desired target color in real time, thereby improving the overall efficiency and accuracy of color difference protectant preparation and making the preparation process more controllable.

[0032] 2. The sampling valve assembly of this utility model not only enables convenient and rapid real-time sampling during the preparation process, but also does not significantly affect the stirring of the sample inside the cylinder, and the sample collected in the sampling bottle is more uniform. Moreover, the sample inside the cylinder is forced into the sampling bottle under liquid pressure until the sampling bottle is full of small sample, so that the sample volume can be basically consistent each time without additional control, simplifying the overall preparation process, improving the accuracy of sampling, and facilitating the subsequent determination of the sample composition ratio.

[0033] 3. This utility model can simultaneously prepare a small volume of supplementary sample during the sample preparation process, thereby allowing a supplementary sample with a volume and ratio basically consistent with the sample to be added to the cylinder after each sampling, reducing the error in the final scale-up preparation and improving the accuracy of color matching.

[0034] 4. This utility model can enable all the outlets at the bottom of the same color mixing bottle to be opened or closed at the same time, thereby adding the same volume of colorant to all the replenishment bottles at the same time, further improving the consistency of the sample ratio in the replenishment bottle with the sample ratio in the current cylinder, and simplifying the sample preparation process.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0045] Example 1:

[0046] like Figures 1 to 3 A color matching device for adjusting the color difference of concrete is shown, including a cylinder 1, a cover 2 on the cylinder 1, a feeding port 5 and a first motor 3 on the cover 2, the output end of the first motor 3 movably passes through the cover 2 and is connected to a stirring paddle 4 located inside the cylinder 1, and a sampling port 11 and a sampling valve assembly 6 are also provided on the side wall of the cylinder 1. The sampling valve assembly 6 is used to install a sampling bottle 7 and to open or close the sampling port (11).

[0047] The sampling valve assembly 6 includes a slider 61 with a connecting port 62 extending through it. The connecting port 62 is used to install the sampling bottle 7. The slider 61 can move along the outer wall of the cylinder 1 to an open or closed state. In the open state, the connecting port 62 connects the sampling bottle 7 and the sampling port 11. In the closed state, the slider 61 blocks the sampling port 11.

[0048] In some embodiments, the color matching device may further include a color difference tester, which can be any existing color difference tester. The color difference tester is used to collect the color characteristics of the color difference protectant sample in the current cylinder in real time to determine whether sampling is necessary. In one or more embodiments, the color difference tester and the color matching device may be a set of devices or two independent sets of devices.

[0049] In some embodiments, a groove 12 is provided on the outer wall of the cylinder 1, and the slider 61 is installed in the groove 12 and can move up and down along the groove 12.

[0050] In some embodiments, such as Figure 2 and Figure 3 As shown, a guide groove 13 is provided in the slide groove 12, and a guide rod 64 is slidably disposed in the guide groove 13. The guide rod 64 is fixedly connected to the slider 61.

[0051] In one or more embodiments, a spring 63 is provided inside the slide 12, and the spring 63 is connected to the slider 61. In some preferred embodiments, the lower limit of the slide's stroke is in the open state, and the spring is located above the slider. When the sampling valve assembly is in the closed state, the spring is in the stretched state. When it is necessary to switch the sampling valve assembly to the open state, a sampling bottle is installed on the connection port. The weight of the sampling bottle causes the slider to overcome the elastic force and move downward to its lower limit of stroke. After the sample fills the sampling bottle, the sampling bottle is removed, and the slider returns to the closed state under the action of the elastic force, and the connection port is sealed.

[0052] In one or more embodiments, the cover 2 is provided with an observation window 14. The observation window allows for real-time observation of the stirring process inside the cylinder, and also allows for real-time acquisition of sample color using a colorimeter through the observation window or an open observation window.

[0053] Example 2:

[0054] like Figures 1 to 5 The color matching device shown is for adjusting color difference in concrete, comprising:

[0055] A sample preparation device includes a cylindrical body 1, a cover 2 on the cylindrical body 1, a feeding port 5 and a first motor 3 on the cover 2, the output end of the first motor 3 movably passing through the cover 2 and connected to a stirring paddle 4 located inside the cylindrical body 1, and a sliding groove 12 on the side wall of the cylindrical body 1, the sliding groove 12 having a sampling port 11 communicating with the inside of the cylindrical body 1, and a slider 61 moving along the sliding groove 12, the slider 61 having a connecting port 62 passing through the slider 61. The connection port 62 is used to install the sampling bottle 7; the slider 61 can move along the outer wall of the cylinder 1 to an open state or a closed state. In the open state, the connection port 62 connects the sampling bottle 7 and the sampling port 11. In the closed state, the slider 61 blocks the sampling port 11. The supplementary device includes a base 81, on which at least one station 88 for installing a supplementary bottle 9 is provided. The volume of the supplementary bottle 9 is equal to the volume of the sampling bottle 7.

[0056] In use, after adding the initial color difference protectant sample (e.g., 500 ml) to the cylinder, add an equal volume of the reduced color difference protectant sample (e.g., 50 ml) to the replenishment bottle. Subsequently, each time toner is added to the color difference protectant sample, the same volume ratio of toner is added to the replenishment bottle. For example, when adding 2 ml of black toner to the cylinder, 0.2 ml of black toner is added dropwise to the replenishment bottle. In this way, the color difference protectant sample in the replenishment bottle maintains a substantially consistent ratio with the color difference protectant sample in the cylinder, and the color difference protectant in the replenishment bottle does not require stirring.

[0057] In some embodiments, a color mixing bottle 85 is also included. The bottom of the color mixing bottle 85 is provided with at least one discharge port. A rotary valve 87 is provided inside the color mixing bottle 85. The rotary valve 87 is used to open or close the discharge port. A bracket 82 is provided on the base 81. A second motor 83 is provided on the bracket 82. A rotating rod 84 is connected to the output end of the second motor 83. The rotating rod 84 is connected to each rotary valve 87.

[0058] In one or more embodiments, multiple color mixing bottles can be set at the same time, and each color mixing bottle corresponds to a rotary valve and a second motor. When it is necessary to add a certain color of toner, the corresponding rotary valve can be driven to rotate and open.

[0059] In some embodiments, a feeding hopper 86 is also included, the feeding end of which is connected to the discharge port of the color mixing bottle 85, and the discharge end of the feeding hopper 86 is connected to the replenishment bottle 9.

[0060] In some embodiments, the volume of the replenishment bottle is 0.05 to 0.1 times the volume of the color difference protectant sample prepared in the cylinder 1.

[0061] Example 3:

[0062] Based on the aforementioned embodiments, a matching method for controlling the apparent color difference of concrete using the aforementioned color matching device includes the following steps:

[0063] Prepare a color difference protection agent sample and obtain the first color difference between the sample color of the color difference protection agent sample and the target color of the target concrete;

[0064] When the first color difference is lower than the first threshold, a sample is taken from the color difference protectant sample and the ratio of the color difference protectant sample is recorded. A color block is made based on the sample taken, and the second color difference between the color block color and the target color is obtained.

[0065] When the second color difference is lower than the second threshold, the final color block is obtained, and the color difference protection agent is prepared according to the ratio of the color difference protection agent sample corresponding to the final color block;

[0066] The color difference protectant is sprayed onto the area to be repaired.

[0067] In some preferred embodiments, the volume of the color difference protectant sample should not be too small; otherwise, uneven mixing and insufficient toner addition will lead to significant errors. This will result in a color difference protectant with even greater errors after scaling up the preparation according to the final color patch ratio. Conversely, preparing an excessively large volume of color difference protectant sample will significantly increase preparation costs. Similarly, the volume of each sample should not be too small to avoid large errors, while larger sample volumes require larger volumes of color difference protectant sample. Therefore, the volume of the color difference protectant sample is preferably 0.02 to 0.1 times the final required volume. For example, if 40 liters of color difference protectant needs to be prepared, the volume of the color difference protectant sample can be controlled at 1 liter. The sample volume for each color patch preparation is preferably 0.05 to 0.1 times the volume of the color difference protectant sample, for example, 50 milliliters.

[0068] In some preferred embodiments, the target color of the target concrete and the color of the color difference protection agent sample can be acquired using a colorimeter. Based on the Lab and Lch principles of the CIE color space, the first color difference between the target color and the sample color is measured, such as ΔE or ΔLab values. Whether the first color difference is lower than a preset first threshold determines whether the sample color has met the requirements for extracting a portion of the sample to create a color patch. The first threshold corresponds to the difference in lightness, red / green, yellow / blue, and / or total color difference between the sample color and the target color. The second threshold corresponds to the total color difference between the color patch color and the target color. In this embodiment, both the first and second thresholds can be the total color difference. One or more color patches are determined by setting the values ​​of the first and second thresholds. The first threshold can also be, for example, Δa and Δb equal to 0, and ΔL a positive or negative value close to 0; or Δa and ΔL equal to 0, and Δb a positive or negative value close to 0; or Δb and ΔL equal to 0, and Δa a positive or negative value close to 0. This provides more samples to create color patches, using multiple color patches of different colors to reduce color difference changes during the color patch drying process, resulting in a more consistent color difference protectant sample. In some preferred embodiments, when adjusting the brightness difference, red / green difference, or yellow / blue difference between the sample color and the target color, at least three color patches are obtained.

[0069] In this technical solution, the color adjustment of the color difference protection agent sample is achieved by adding a colorant to the sample. For example, black, yellow, or red colorants can be added to the sample to gradually reduce the color difference between the sample color and the target color until the first color difference is below a first threshold, indicating that the current sample color is relatively close to the target color. At this point, a certain amount of sample can be taken from the color difference protection agent sample to prepare a corresponding color block, and the color matching corresponding to the color block is recorded, i.e., the initial volume of the color difference protection agent sample and the type and volume of the currently added colorant. By presenting the taken sample on the color block, the color that appears after the current color matching is applied to the concrete and the color no longer changes can be obtained, i.e., the color of the color block. By comparing the second color difference between the color block color and the target color, the color of the prepared color difference protection agent sample after being applied to the concrete surface can be intuitively presented, reducing the influence of color changes caused by concrete material, temperature, and pigments during the drying process on the color applied to the concrete, thereby making the color of the prepared color difference protection agent sample closer to the desired concrete surface color.

[0070] In this technical solution, when the second color difference between the color of a certain color block and the target color is lower than the second threshold, it indicates that the sample color presented on the color block meets the requirements of the target color. This color block is the final color block, and the color composition of the sample corresponding to the final color block can be scaled up to prepare a large number of color difference protection agents.

[0071] The above control method can adjust the sample color of the color difference protectant sample based on the target color, so that the prepared sample color is closer to the target color and the prepared color is more accurate. At the same time, after obtaining one or more sample colors with a first color difference lower than the first threshold, by taking out a portion of the sample to make color blocks, the influence of color changes caused by factors such as concrete material and pigments on the final color difference during the drying process of the color applied to the concrete can be reduced, which significantly improves the color consistency between the color difference protectant and the target color.
