[0023] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5, the utility model provides an embodiment: a concrete durability simulation device based on a corrosive environment, comprising a concrete simulation device 1, wherein a simulation cavity is provided inside the concrete simulation device 1, an infusion box 3 19 is installed inside the concrete simulation device 1, a water pump 1 20 is installed on the bottom wall of the infusion box 3 19, a delivery pipe 18 is installed on the output end of the water pump 1 20, one end of the delivery pipe 18 is located in the simulation cavity, an electronic control valve 25 is installed on the outer surface of the delivery pipe 1 18, a delivery pipe 22 is installed on one side outer wall of the concrete simulation device 1, a water pump 21 is installed on one end of the delivery pipe 22, a connecting pipe 24 is installed on the output end of the water pump 21, one end of the connecting pipe 24 is located inside the infusion box 3 19, two sets of filter screens are installed inside the infusion box 3 19, the filter screens are located between the water pump 1 20 and the connecting pipe 24, an electronic control valve 1 23 is installed on the outer surface of the delivery pipe 22, and an ultraviolet lamp 30 is installed on the top wall of the simulation cavity;

[0024] The concrete sample to be tested is fixed with a clamping assembly, and then the simulation cavity can simulate various corrosion environments in order to conduct a real and accurate test of the durability characteristics of the sample, thereby improving the various situations of environmental simulation and expanding the application range of the device. The infusion tank 3 19 is filled with seawater or salt water with the same salinity as seawater. When conducting marine environment simulation, the water pump 1 20 and the electronic control valve 2 25 are turned on to allow the seawater in the infusion tank 3 19 to enter the simulation cavity. After the seawater in the simulation cavity completely submerges the sample, the water pump 1 20 is stopped from continuing to work to simulate the concrete being immersed in seawater. Then, the water pump 1 20, the electronic control valve 2 25, the electronic control valve 1 23 and the water pump 2 21 are turned on at the same time to enable the water pump 1 20 to pump the seawater in the infusion tank 3 19 into the simulation cavity. During the circulation process, the water pump 21 draws the seawater in the simulation cavity back to the infusion tank 3 19 to simulate the fluctuation of seawater. The filter in the infusion tank 3 19 is used to intercept impurities in the seawater returned from the simulation cavity to the infusion tank 3 19 to prevent the impurities from being drawn into the simulation cavity again by the water pump 1 20, thereby ensuring that the seawater entering the simulation cavity is always kept clean and reducing the interference of other factors. In addition, the ultraviolet lamp 30 is turned on regularly to irradiate the sample with ultraviolet light to simulate the environment in which the concrete is exposed to ultraviolet light during the day, thereby improving the dynamic reality of the marine environment simulation and helping to more accurately detect the durability characteristics of concrete in the actual marine environment. By dynamically simulating the seawater conditions and ultraviolet radiation conditions of the marine environment, the authenticity and applicability of the concrete corrosion environment simulation are improved.

[0025] Two groups of electric push rods three are installed on the inner wall of one side of the simulation chamber, and the output ends of the two groups of electric push rods three are installed with an atomizing nozzle one 10. A liquid storage tank two 4 is installed on the outer wall of one side of the concrete simulation device 1. The liquid storage tank two 4 is composed of a liquid storage chamber one and a liquid storage chamber two. The liquid storage chamber one is located in front of the liquid storage chamber two. A small water pump one 6 is installed on the bottom wall of the liquid storage chamber one, and a liquid infusion tube two 12 is installed on the output end of the small water pump one 6. One end of the liquid infusion tube two 12 is connected to the top of one group of atomizing nozzle one 10. A small water pump two 7 is installed on the bottom wall of the liquid storage chamber two, and a liquid infusion tube one 11 is installed on the output end of the small water pump two 7. One end of the liquid infusion tube one 11 is connected to the top of another group of atomizing nozzle one 10.

[0026] The top of the liquid storage tank 2 4 is equipped with a liquid inlet pipe 1 5 and a liquid inlet pipe 2 9. The liquid inlet pipe 2 9 is located behind the liquid inlet pipe 1 5. The liquid inlet pipe 1 5 is connected to the liquid storage chamber 1, and the liquid inlet pipe 2 9 is connected to the liquid storage chamber 2.

[0027] A low-temperature refrigerator 16 and a ventilator 17 are installed on one side of the outer wall of the concrete simulation device 1. The ventilator 17 is located above the low-temperature refrigerator 16, and the low-temperature refrigerator 16 is located behind the delivery pipe 18. The top of the low-temperature refrigerator 16 is installed with an air delivery pipe 15. A temperature and humidity sensor 26 is installed on one side of the inner wall of the simulation chamber by bolts.

[0028] The liquid storage chamber 1 and the liquid storage chamber 2 in the liquid storage tank 2 4 are used to store pure water and salt solution respectively. The corrosion of concrete in a salty and humid environment is simulated by spraying salt mist. The low-temperature refrigerator 16 and the heating block 33 are used to simulate the effect of freeze-thaw cycles on concrete in cold areas. In addition, the two can be used in combination to simulate the corrosion of concrete during winter road deicing. The corrosion environment simulation can be performed separately or in combination to simulate a more complex corrosion environment, thereby achieving a more comprehensive environmental simulation to improve the simulation adaptability of the device to different corrosion environments. The salt solution is stored in the liquid storage chamber 2 and flows to the atomizing nozzle 10 under the action of the small water pump 27. The salt solution is formed into a mist under the action of the atomizing nozzle 10 and the salt mist is sprayed on the surface of the sample to evaluate the corrosion of concrete in a salty and humid environment. The small water pump 27 is turned on to send the water in the liquid storage chamber 1 to the atomizing nozzle 10. The atomized water is sprayed on the surface of the sample under the atomization action of the atomizing nozzle 10. Then the low-temperature refrigerator 16 is turned on to allow the temperature in the simulation chamber to drop rapidly. When the temperature drops to a certain level, When the temperature drops to zero, the cooling is stopped and the heating block 33 is turned on. The heating block 33 heats the sample, causing the frozen concrete to heat up and melt the ice on the sample surface. This process is repeated to simulate the freeze-thaw cycle of concrete to test the corrosion resistance of the concrete. In addition, atomized water can be sprayed on the sample surface first, and then the low-temperature refrigerator 16 is turned on to quickly freeze the sample. Then, salt spray is sprayed to thaw the frozen concrete, simulating the corrosion of concrete caused by the use of deicing salt during winter road deicing. The temperature of the simulation chamber can also be increased by the heating block 33. When the temperature rises to a certain level, the atomizing nozzle 10 sprays atomized water onto the sample surface. The temperature and humidity sensor 26 is used to detect the current temperature and humidity in the simulation chamber, making the simulation chamber a high temperature and high humidity environment to simulate the corrosion conditions in tropical or subtropical humid climates. The interaction between the heating block 33 and the low-temperature refrigerator 16 simulates the effects of day and night temperature differences and seasonal changes on concrete, greatly increasing the environmental conditions that can be simulated by the device and improving the scope of use of the device. The ventilator 17 is used to quickly replace the air in the simulation chamber after the test.

A liquid inlet pipe 3 14 is installed on the top of the liquid storage tank 3.

[0030] The liquid storage tank 3 is used to store the acidic solution. The acidic solution is pumped to the ultraviolet lamp 30 through a small water pump 3. Under the action of the ultraviolet lamp 30, the acidic solution is atomized and sprayed on the sample surface to simulate the corrosion of concrete in an acid rain environment.

[0031] The bottom wall of the simulation chamber is installed with a clamping assembly, which is used to clamp the concrete sample to be tested. The clamping assembly includes two sets of electric push rods 27 installed on the bottom wall of the simulation chamber, and the output end of the electric push rod 27 is installed with an electric push rod 31, and the output end of the electric push rod 31 is installed with a clamping plate 32. The bottom wall of the simulation chamber is installed with a heating block 33, which is located between the two sets of electric push rods 27 and below the clamping plate 32.

[0032] The second electric push rod 31 extends, driving the two clamping plates 32 to approach each other until the concrete sample is clamped between the two sets of clamping plates 32. In addition, the extension length of the electric push rod 1 27 can be adjusted according to the actual size and height of the concrete sample to better clamp and fix the sample.

[0033] A camera 28 is mounted on the top wall of the simulation chamber, and the camera 28 is located in front of the second atomizing nozzle 29.

[0034] The camera 28 is used to monitor the progress of the environmental simulation in real time.

The controller 8 is used to control and monitor the specific simulation situation of the device.

[0035] Working principle: The concrete sample to be tested is fixed with a clamping assembly, and then different corrosion environments are simulated according to the test requirements to test the durability of the concrete. When simulating the marine environment, the water pump 1 20 and the electronic control valve 2 25 are turned on to allow the seawater in the infusion tank 3 19 to enter the simulation cavity. After the seawater in the simulation cavity completely submerges the sample, the water pump 1 20 is stopped and continues to work to simulate the concrete being immersed in seawater. Then, the water pump 1 20, the electronic control valve 2 25, the electronic control valve 1 23 and the water pump 2 21 are turned on at the same time to realize the cycle process in which the water pump 1 20 pumps the seawater in the infusion tank 3 19 into the simulation cavity, and the water pump 2 21 pumps the seawater in the simulation cavity back to the infusion tank 3 19 to simulate seawater fluctuations.
