[0033] The present application embodiment provides a reinforced concrete structure corrosion system, referring to Figure 1 , Figure 1The overall structure diagram of the reinforced concrete structure corrosion system is shown. The reinforced concrete structure corrosion system includes: a simulation mechanism 1, a liquid storage mechanism 2 and a control mechanism 3; wherein the simulation mechanism 1 is provided with a simulation space, and the test block 4 is placed in the simulation space; a simulation structure adapted to the test block 4 is provided in the simulation space to simulate the corrosion of the test block 4; the liquid storage mechanism 2 is provided with a containing space, and the containing space is used to contain the corrosive solution; a monitoring structure is provided in the containing space to monitor and adjust the state of the corrosive solution; the liquid storage mechanism 2 is connected with the simulation mechanism 1 to transport the corrosive solution into the containing space; the control mechanism 3 is provided with a switching structure, and the simulation mechanism 1 and the liquid storage mechanism 2 are electrically connected to the switching structure respectively, and the simulation mechanism 1 and / or the liquid storage mechanism 2 are adjusted to the corresponding state through the switching structure.

[0034] In an embodiment of the present application, the simulation mechanism 1 may be provided with a simulation space, and the simulation space may be used to provide an installation environment for the test block 4 and other structures; for example, the test block 4 and the simulation structure may be installed in the simulation space, the simulation structure and the test block 4 may be matched, and the corrosion of the test block 4 may be simulated using the simulation structure.

[0035] Exemplarily, taking the test block 4 as a reinforced concrete test block, other positions in the text are referred to as test block 4, and the simulation structure may include components with a hollow structure, such as a shell, etc. The hollow structure of the shell is the simulation space.

[0036] As another example, the simulation structure may be a structure capable of creating a wet environment and a dry environment, such as a spraying structure and a drying structure; by spraying a corresponding solvent on the test block 4 or creating a dry environment for the test block 4, the corrosive environment of the test block 4 is simulated.

[0037] In the embodiment of the present application, the liquid storage mechanism 2 can be provided with a holding space to provide storage space for the corrosive solution or the corrosive solution mixture; taking the storage of the corrosive solution mixture in the holding space as an example, a monitoring device adapted to the corrosive solution mixture can also be provided in the holding space to monitor the concentration, temperature and other indicators of the corrosive solution mixture, and then adjust it according to the set parameters; the liquid storage mechanism 2 can be connected to the simulation mechanism 1, so as to transport the corrosive solution mixture in the holding space to the simulation space.

[0038] Exemplarily, the liquid storage mechanism 2 may include a structure with a containing space, such as a box body, a case body, etc. Taking the case body as an example, the space inside the case body is the containing space, and the corrosive solution may be placed in the containing space.

[0039] Among them, the parts used for storing the corrosive solution have good corrosion resistance, and the corresponding parts can be selected according to the corrosive solution to be used and other requirements.

[0040] As another example, a monitoring structure, such as a temperature monitoring structure, a concentration detection structure, etc., may be provided in the accommodation space to monitor the temperature and concentration of the corrosion solution in the accommodation space, and to adjust the temperature and concentration of the corrosion solution.

[0041] It is understandable that the corrosion solution used to corrode the test block 4 may be a mixed solution, that is, a corrosion solution obtained by mixing the corrosion liquid with other solvents. The concentration of the corrosion solution may be adjusted by adding corresponding solvents or corrosion liquids to meet the simulation requirements.

[0042] As another example, the liquid storage mechanism 2 can be connected to the simulation mechanism 1 through a connecting pipe or other means, the corrosion solution in the liquid storage mechanism 2 is transported to the simulation mechanism 1, and the corrosion solution is brought into contact with the test block 4 to perform corrosion simulation on the test block 4.

[0043] In an embodiment of the present application, a switching structure may be provided in the control mechanism 3, and the simulation mechanism 1 and the liquid storage mechanism 2 may be electrically connected to the switching structure. The switching structure may control the opening and closing of the channels of the liquid storage mechanism 2 and the simulation mechanism 1, and may control the opening and closing of the corresponding simulation structure in the simulation mechanism 1, thereby realizing the switching of the simulation environment in the simulation mechanism 1.

[0044] Exemplarily, the switching structure can be a corresponding controller, and the type of controller is selected according to actual needs. The controller can control the opening and closing of part of the simulation structure in the simulation mechanism 1, or control the opening and closing of the delivery channel between the liquid storage mechanism 2 and the simulation mechanism 1 in the corresponding time period.

[0045] In the above embodiment, since the simulation mechanism 1 is provided, the environment required for corroding a reinforced concrete structure can be simulated through the simulation mechanism 1, and the simulation mechanism 1 can protect the test block 4 and reduce the influence of the external environment on the test block 4; since the liquid storage mechanism 2 is provided, the liquid storage mechanism 2 can protect the corrosive solution and reduce the influence of the external environment on the corrosive solution, and the corrosive solution can be kept in a constant state; since the control mechanism 3 is provided, different simulated corrosion environments can be switched through the control mechanism 3, the degree of automation is high, and the corrosion efficiency is improved.

[0046] In some embodiments of the present application, reference Figure 2 , Figure 2 A front view of a reinforced concrete structure corrosion system is shown, wherein the simulation mechanism 1 comprises a protective device 11, a supporting device 12 and a test device 13; the protective device 11 forms a simulation space, the supporting device 12 and the test device 13 are arranged in the simulation space, the test block 4 is placed on the supporting device 12, the test device 13 is arranged at a position on the protective device 11 corresponding to the test block 4, and the corrosion simulation of the test block 4 is performed by the test device 13.

[0047] Exemplarily, the simulation mechanism 1 can be configured as a structure including a protective device 11, a supporting device 12 and a test device 13. The protective device 11 can form a simulation space, for example, the protective device 11 can be configured as a structure including a protective component, and the protective component can be enclosed to form a receiving space.

[0048] Among them, the protective component can be a structural form including a test box 111, and an opening can be set on one side of the test box 111, through which the test block 4 is placed into the test box 111 or the test block 4 is taken out of the test box 111; a baffle is connected to the opening position, and the baffle is not marked in the figure. The test box 111 has a certain corrosion resistance, which reduces the probability of the inside of the test box 111 being corroded by the corrosive solution. In the embodiment of the present application, the material, molding method, etc. of the test box 111 are not specifically limited.

[0049] In another example, the support device 12 can be arranged in the simulation space, that is, the support device 12 can be arranged in the test box 111. For example, the support assembly can be arranged in a structural form including a support column 121 and a support plate 122. The number of the support columns 121 can be four, and the four support columns 121 are respectively placed on the bottom surface of the test box 111. The support columns 121 and the support plate 122 should meet the corrosion resistance requirements. The test block 4 can be placed on the support plate 122, and the test block 4 is supported by the support plate 122.

[0050] The support column 121 can be placed inside the test box 111, or the support column 121 can be installed inside the test box 111 by other connection methods, as long as the stability requirements are met. The support plate 122 can be placed on the top of the support column 121, or the support plate 122 can be integrally formed with the support column 121. The size of the support plate 122 can be selected according to the size of the test block 4, and the shape of the support plate 122 can be selected according to the shapes of the test block 4 and the test box 111.

[0051] In addition, the support plate 122 may be provided with filter holes, which are not marked in the figure, so that the corrosion solution on the test block 4 can flow to the bottom of the test box 111 through the filter holes, reducing the probability of affecting the corrosion efficiency due to the accumulation of the corrosion solution on the support plate 122.

[0052] In another example, the test device 13 can be installed on the inner wall of the test box 111, and the test block 4 is subjected to corrosion simulation by the test device 13. For example, the test device 13 can be configured to include a drying component, and the drying component can be an infrared lamp 131. The number of infrared lamps 131 can be 4, and the 4 infrared lamps 131 are respectively installed on the 4 inner walls of the test box 111, that is, the 4 infrared lamps 131 are arranged on the surrounding side of the test block 4. Such an arrangement can provide uniform heat to the test block 4. The embodiment of the present application does not specifically limit the number and installation position of the infrared lamps 131, and they are arranged according to actual conditions.

[0053] For another example, the test device 13 may be configured to include a spray plate 132 , which is installed inside the test box 111 and is located directly above the test block 4 , so that the spray plate 132 can spray the corrosion solution onto the test block 4 .

[0054] In the above embodiment, since a protective component is provided, the test block 4 is protected by the protective component, thereby reducing the influence of external factors on the test block 4; since a supporting component is provided, the test block 4 is supported by the supporting component, and the test block 4 is convenient to take; since a test device 13 is provided, different environments can be provided by the test device 13 to simulate corrosion of the test block 4.

[0055] In some embodiments of the present application, reference Figure 3 , Figure 3 The schematic diagram of the electrical connection structure between the various parts is shown. Figure 2 and Figure 3 As shown, the liquid storage mechanism 2 includes a liquid storage device 21, a monitoring and adjusting device 22 and a conveying device 23; the liquid storage device 21 has a containing space; the monitoring and adjusting device 22 is connected to the liquid storage device 21 for monitoring and adjusting the concentration of the corrosion solution; the conveying device 23 is connected to the wetting component to spray the corrosion solution in the containing space onto the test block 4 through the wetting component.

[0056] Exemplarily, the liquid storage mechanism 2 can be configured to include a liquid storage device 21, a monitoring and regulating device 22, and a conveying device 23, wherein the liquid storage device 21 can be configured to include a liquid storage component, and the liquid storage component has a storage space; for example, the liquid storage component includes a water storage tank 211, and the top of the water storage tank 211 is provided with an opening, and a cover plate is connected to the position of the opening, and the cover plate is not marked in the figure. The water storage tank 211 and the cover plate should meet the corrosion resistance requirements.

[0057] In another example, the monitoring and regulating device 22 can be configured to include a temperature regulating component 221, a temperature monitoring component 222, and a concentration monitoring component 223. The temperature regulating component 221 can be installed on the inner bottom surface of the water storage tank 211, and the temperature monitoring component 222 and the concentration monitoring component 223 are installed on the inner side wall of the water storage tank 211. The temperature regulating component 221 can be electrically connected to the temperature monitoring component 222. When the temperature monitoring component 222 detects that the temperature in the water storage tank 211 is out of the predetermined parameters, the temperature regulating component 221 can be controlled to start and adjust the temperature of the corrosive solution in the water storage tank 211.

[0058] The temperature regulating member 221 may be a temperature regulating plate, and the size of the temperature regulating plate may be set according to the size of the water storage tank 211. The temperature monitoring member 222 may be a temperature sensor and controller, that is, the temperature monitoring member 222 has the functions of temperature sensing and temperature control, so that the temperature monitoring member 222 can monitor the temperature and control the opening and closing of the temperature regulating member 221 according to the monitored temperature.

[0059] In the above embodiment, since a liquid storage component is provided, the corrosive solution can be placed in a closed space through the provided liquid storage component, thereby reducing the probability that the corrosive solution is affected by exposure to the outside world; since a monitoring and adjustment device 22 is provided, the temperature, concentration, etc. of the corrosive solution can be monitored and adjusted through the provided monitoring and adjustment device 22, so that the corrosive solution in the liquid storage component is maintained in a constant state; since a conveying device 23 is provided, the conveying device 23 can convey the corrosive solution in the liquid storage component to the inside of the test box 111, so as to perform corrosion simulation on the test block 4.

[0060] In some embodiments of the present application, Figure 2 and Figure 3 As shown, the liquid storage component is connected to the storage component 25 and the water inlet component 24, the temperature adjustment component 221 is electrically connected to the temperature monitoring component 222, and the storage component 25 and the water inlet component 24 are both electrically connected to the concentration monitoring component 223; the conveying device 23 includes a conveying component, one end of the conveying component is connected to the liquid storage component, and the other end is connected to the wetting component.

[0061] In the embodiment of the present application, the liquid storage component can be connected to a storage component 25, and the storage component 25 is used to store corrosive reagents. The corrosive reagents in the storage component 25 can enter the liquid storage component; the liquid storage component can also be connected to a water inlet component 24, and other solutions can be transported to the liquid storage component through the water inlet component 24. The storage component 25 and the water inlet component 24 can be electrically connected to the concentration monitoring component 223, and the concentration monitoring component 223 can control the opening and closing of the storage component 25, and the concentration monitoring component 223 can control the opening and closing of the water inlet component 24. The conveying device 23 can be set to a structural form including a conveying component, one end of the conveying component can be connected to the liquid storage component, and the other end can be connected to the wetting component.

[0062] Exemplarily, the storage assembly 25 can be configured to include a storage box 251. For example, the storage assembly includes a water storage tank 211. The storage box 251 can be installed on the side wall of the water storage tank 211. The storage box 251 is used to store corrosive reagents. The storage box 251 has good corrosion resistance. The embodiment of the present application does not specifically limit the number and size of the storage boxes 251, as long as they meet the work requirements.

[0063] It is understandable that the placement box 251 can be installed on the outer wall of the water storage tank 211 to facilitate the addition of the corrosive solvent into the placement box 251. The placement box 251 is detachably connected to a box cover, and the placement box 251 is sealed by the box cover to reduce the influence of external factors on the corrosive reagent in the placement box 251. A structure electrically connected to the concentration monitoring component 223 is provided at the location of the corrosive reagent outflow port on the placement box 251, and the opening of the placement box 251 can be controlled by the concentration monitoring component 223 and the mechanism.

[0064] In another example, the water inlet component 24 may include a first water pump 241, the water outlet end of the first water pump 241 may be connected to the water storage tank 211, the water inlet end of the first water pump 241 may be connected to a water inlet pipe, which is not marked in the figure, a first flow control valve 242 is installed at the water outlet end of the first water pump 241, and the water outlet end of the first water pump 241 is connected to the water storage tank 211, and the concentration monitoring component 223 is electrically connected to the first flow control valve 242, that is, the concentration monitoring component 223 can control the opening and closing of the first flow control valve 242.

[0065] In another example, the delivery assembly may include a second water pump 231, the water inlet end of the second water pump 231 may be connected to a second water inlet pipe 233, the second water inlet pipe 233 is connected to the water storage tank 211; the water outlet end of the second water pump 231 may be connected to a first connecting pipe 234, the first connecting pipe 234 may be connected to the spray plate 132. A second flow control valve 232 may be installed on the first connecting pipe 234, and the second flow control valve 232 may control the flow and closing of the first connecting pipe 234.

[0066] Among them, the second water inlet pipe 233 and the first connecting pipe 234 both have certain anti-rust function and corrosion resistance performance to improve the working efficiency of the reinforced concrete structure corrosion system.

[0067] It should be explained that the concentration monitoring component 223 can be a corrosion ion concentration detector and controller, that is, the concentration monitoring component 223 can detect the concentration of corrosion ions in the corrosion solution in the water storage tank 211, and compare the detected concentration with the set parameters to control the opening and closing of the first flow control valve 242 and the placement box 251.

[0068] In the above embodiment, since a storage component 25 and a water inlet component 24 are provided, the concentration of the corrosive solution in the liquid storage component can be adjusted to a constant state through the storage component 25, the water inlet component 24 and the concentration monitoring component 223; since a conveying component is provided, the corrosive solution in the liquid storage component can be conveyed to the simulation space through the conveying component.

[0069] In some embodiments of the present application, Figure 2 and Figure 3 As shown, a stirring member 5 is connected to a position on the liquid storage component corresponding to the temperature monitoring member 222 , and the stirring member 5 is electrically connected to the concentration monitoring member 223 .

[0070] In the embodiment of the present application, the liquid storage assembly may be provided with installation points or structures for installing the stirring member 5. The stirring member 5 is installed at a position corresponding to the temperature monitoring member 222, and the stirring member 5 can be electrically connected to the concentration monitoring member 223, that is, the concentration monitoring member 223 can control the opening and closing of the stirring member 5.

[0071] Exemplarily, the stirring member 5 may be a stirring fan blade. Taking the liquid storage component as the water tank 211 as an example, the stirring fan blade may be installed on the inner wall of the water tank 211 .

[0072] As another example, the stirring fan blades can be installed on the inner wall of the water tank 211 close to the inner bottom surface of the water tank 211. Such an arrangement makes it easier to stir the corrosive solution in the water tank 211 evenly.

[0073] In the above embodiment, since the stirring member 5 is provided, when the solvent in the storage component 25 or the water inlet component 24 enters the liquid storage component, the stirring member 5 can be started to stir the corrosion solution in the liquid storage component evenly, thereby improving the corrosion efficiency.

[0074] In some embodiments of the present application, Figure 2 and Figure 3 As shown, the control mechanism 3 includes a time controller 31, and the conveying component and the drying component are both electrically connected to the time controller 31.

[0076] Exemplarily, the time controller 31 can be arranged on one side of the second water pump 231, so that it is convenient to connect with the second water pump 231. The time controller 31 can be connected to the second water pump 231 through a wire 8, the time controller 31 can be connected to the second flow control valve 232 through a wire 8, and the time controller 31 can be connected to the infrared lamp 131 through a wire 8.

[0077] In the above embodiment, since the time controller 31 is provided, the time controller 31 can switch different stages to perform corrosion simulation on the test block 4, thereby improving the automation level of the reinforced concrete structure corrosion system.

[0078] In some embodiments of the present application, Figure 2 and Figure 3 As shown, a reflux component 6 is arranged between the protective component and the liquid storage component; one end of the reflux component 6 is connected to the protective component, and the other end is connected to the liquid storage component; a liquid level monitoring component 61 is installed on the protective component, and the liquid level monitoring component 61 is electrically connected to the reflux component 6 so that the liquid in the protective component can flow back into the liquid storage component.

[0079] In the embodiment of the present application, a reflux component 6 can be provided between the protection component and the liquid storage component, and the corrosive solution in the protection component can be refluxed into the liquid storage component through the reflux component 6. One end of the reflux component 6 can be connected to the protection component, and the other end can be connected to the liquid storage component. A liquid level monitoring component 61 can be installed in the protection component, and the liquid level in the protection component can be monitored by the liquid level monitoring component 61, and the liquid level monitoring component 61 can be electrically connected to the reflux component 6, and the opening and closing of the reflux component 6 can be controlled by the liquid level monitoring component 61.

[0080] Exemplarily, the reflux component 6 may include a third water pump 62. Taking the example of the protection component including the test box 111 and the liquid storage component including the water tank 211, the water inlet end of the third water pump 62 is connected to the test box 111 through a water pipe, and the water outlet end of the third water pump 62 is connected to the water tank 211 through a water pipe. The water pipe is not marked in the figure, and a solenoid valve 63 can be installed on the water pipe connecting the third water pump 62 and the water tank 211.

[0081] As another example, the liquid level monitoring component 61 may be a liquid level height sensor and controller, that is, the liquid level monitoring component 61 may monitor the liquid level height, and may also control the opening and closing of the solenoid valve 63 according to the monitored liquid level height.

[0083] In the above embodiment, since a liquid level monitoring component 61 is provided, the liquid level height in the protective component can be monitored by the provided liquid level monitoring component 61; since a reflux component 6 is provided, when the liquid level in the protective component is higher than the set parameter, the reflux component 6 can return the corrosive solution in the protective component to the liquid storage component for recycling, thereby reducing the probability of the corrosion effect being affected by excessive corrosive solution in the protective component.

[0084] In some embodiments of the present application, Figure 2 and Figure 3 As shown, the reinforced concrete structure corrosion system also includes a main control component 7; the temperature monitoring component 222, the concentration monitoring component 223, the time controller 31 and the liquid level monitoring component 61 are all electrically connected to the main control component 7.

[0085] In the embodiment of the present application, the reinforced concrete structure corrosion system can be configured to include a structure that also includes a general control component 7; wherein the temperature monitoring component 222, the concentration monitoring component 223, the time controller 31 and the liquid level monitoring component 61 are all electrically connected to the general control component 7, that is, these components are generally controlled by the general control component 7.

[0087] As another example, taking the case where the main control unit 7 is a computer, standard parameters can be set on the computer, and various parameters can be displayed through the computer, or the reinforced concrete structure corrosion system can be generally controlled through the computer.

[0088] In the above embodiment, since the general control component 7 is provided, overall control can be achieved through the provided general control component 7, thereby further improving the automation level of the reinforced concrete structure corrosion system and further improving the work efficiency.

[0089] The following is an explanation of the use of a reinforced concrete structure corrosion system provided by the present application. When in use:

[0090] S100: First, enter the preparation stage before the corrosion test: open the opening of the test box 111, put the test block 4 on the support plate 122, and close the opening of the test box 111 with a baffle after the placement is completed. Configure each high-concentration corrosion reagent as needed and add it to the corresponding placement box 251, and cover the liquid filling port of the placement box 251 with a box cover after the addition is completed. Preset the liquid level limit in the test box 111, the temperature of the corrosion solution in the water tank 211, the concentration of each corrosion ion in the water tank 211, the water inlet of the water tank 211, the dry-wet cycle period and the number of cycles and the corrosion solution flow rate in the wet stage through the main control unit 7 as needed.

[0091] S200: After the preparation work is completed, the automatic configuration of the corrosion solution stage is entered: the first water pump 241 automatically draws a set amount of deionized water from the outside into the water tank 211. The concentration monitoring component 223 controls the flow of a certain amount of high-concentration corrosion solvent from the placement box 251 into the water tank 211 according to the set concentration of each corrosion ion. In the process of the corrosion solvent in the placement box 251 flowing into the water tank 211, the stirring component 5 rotates and stirs the corrosion solution in the water tank 211, so that the corrosion solution in the water tank 211 can be mixed evenly. The temperature monitoring component 222 can drive the temperature adjustment component 221 to open and close, thereby adjusting the temperature of the corrosion solution in the water tank 211.

[0092] In this process, the concentration monitoring component 223 can control the opening and closing of the first flow control valve 242 or the opening of the placement box 251 according to the concentration of the corrosive solution in the water tank 211. For example, when the concentration monitoring component 223 detects that the concentration of the corrosive solution in the water tank 211 is higher than the set standard, the concentration monitoring component 223 will control the first flow control valve 242 to open, the first water pump 241 to work, and the stirring component 5 to rotate, and draw a certain amount of deionized water from the outside into the water tank 211 as needed. When the concentration of the corrosive solution in the water tank 211 reaches the set concentration, the concentration monitoring component 223 controls the first flow control valve 242 to close, the first water pump 241 to stop working, and the stirring component 5 to stop rotating.

[0093] Alternatively, when the concentration monitoring component 223 detects that the concentration of the corrosive solution in the water tank 211 is lower than the set standard, the concentration monitoring component 223 will control the opening of the placement box 251 to open, and a certain amount of corrosive reagent will flow out of the placement box 251 and enter the water tank 211, and the stirring component 5 will rotate. When the concentration of the corrosive solution in the water tank 211 reaches the set concentration, the concentration monitoring component 223 controls the opening of the placement box 251 to close, and the stirring component 5 stops rotating.

[0094] S300: After the configuration of the corrosion solution is completed, the automatic dry-wet cycle corrosion phase is entered: the wetting phase is performed first: the time controller 31 controls the second water pump 231 and the second flow control valve 232 to continuously extract a fixed amount of corrosion solution from the water storage tank 211 until the set wetting phase ends. In this process, the corrosion solution enters the test box 111 along the first connecting pipe 234, and the corrosion solution is sprayed on the surface of the test block 4 through the spray plate 132. A part of the corrosion solution remains on the surface of the test block 4, and a part passes through the support plate 122 and flows to the inner bottom of the test box 111. When the liquid level monitoring component 61 detects that the corrosion solution at the inner bottom of the test box 111 accumulates to the set liquid level height limit, the liquid level monitoring component 61 controls the third water pump 62 and the solenoid valve 63 to guide the corrosion solution in the test box 111 back to the water storage tank 211.

[0095] After the wet stage is over, the time controller 31 controls the infrared lamp 131 to turn on and enter the drying stage until the set drying stage is over. After the drying stage is over, the time controller 31 controls the infrared lamp 131 to turn off, the second water pump 231 and the second flow control valve 232 to open, and enter the next wet stage. This cycle is repeated until the set number of dry-wet cycles is all over. It can be understood that in the automatic dry-wet cycle corrosion stage, the reinforced concrete structure corrosion system provided by the present application can automatically keep the characteristics of the corrosion solution constant.
