Description

An anti-corrosion soil detection system

Technical field

The invention relates to the technical field of soil detection, specifically an anti-corrosion soil detection system.

Background technique

Soil corrosion is the corrosion of metals in soil. Soil is a special solid electrolyte with capillary porosity. The cathodic process of soil corrosion is mainly oxygen depolarization. Since oxygen has to pass through the solid microporous electrolyte to reach the cathode, the process is complicated and proceeds slowly. Moreover, the structure and humidity of the soil have a great influence on the flow of oxygen. .

According to the patent publication number CN103630487A, a non-ferrous metal soil accelerated corrosion test device is used to detect and determine the corrosiveness of the soil in the experimental area to metal materials. The conductive container of this device is filled with corrosive medium. The upper and lower parts of the metal tube are plugged with upper and lower rubber plugs respectively. The metal tube is placed in the corrosive medium of the conductive container. The upper end of the metal tube is connected to the DC positive terminal and the DC positive wiring. The column is connected to the positive pole of the DC power supply through a wire; a DC negative pole terminal is provided on the outside of the conductive container, and the DC negative pole terminal is connected to the negative pole of the DC power supply through a wire. The invention accelerates the corrosion of non-ferrous metal soil by applying an external direct current and facilitates rapid determination of the corrosiveness of the soil in the experimental area to metal materials. Data related to metal soil corrosion (weight loss) can be quickly obtained in 24 hours. It has a simple structure, convenient measurement, is not subject to geographical restrictions, and is easy to carry. However, this device does not consider various environmental factors when testing metal soil corrosion. The resulting changes in the corrosion rate of metal soil result in the collected relevant data being single and unable to be used as accurate data. For this reason, we provide an anti-corrosion soil detection system.

The bottom of the material box 3 An electric push rod 901 is fixedly installed, and the electric push rod 901 passes through the vibration plate 502. The output shaft of the electric push rod 901 enters the inside of the material box 3 and is fixedly connected to a central axis rod 902. Both ends of the central axis rod 902 are fixed. A cross bar 903 is connected, and the cross bar 903 is slidingly connected to the inner wall of the material box 3. A groove 904 is provided inside the material box 3, and a limit rod 905 is fixedly installed inside the groove 904. The interior of the material box 3 is slidingly connected. There is an extrusion plate 906, and both ends of the extrusion plate 906 are slidably sleeved on the outside of the limit rod 905. A second compression spring 907 is sleeved on the outer side of the limit rod 905, and the extrusion plate 906 passes through the second compression spring. The spring 907 is in elastic contact with the material box 3, and the cross bar 903 can be in extrusion contact with both ends of the extrusion plate 906. Through the contraction of the electric push rod 901, the central axis rod 902 drives the cross bar 903 to move downward, and the cross bar 903 During the downward movement, the extrusion plate 906 will be squeezed, and the extrusion plate 906 will move downward by squeezing the second compression spring 907. During the downward movement of the extrusion plate 906, The sponge layer 802 will be squeezed, thereby squeezing out the water inside the sponge layer 802 and increasing the water absorption of the sponge layer 802, thus simulating the phenomenon in which water inside the soil can continue to penetrate downward after it stops raining in reality.

Please refer to Figure 5. Several grooves 904 are symmetrically formed on both sides of the material box 3, and the heights of the two adjacent grooves 904 are arranged in an arithmetic sequence. The two ends of the two adjacent extrusion plates 906 Connected in a snap-together manner.

Working principle: The collected soil enters the inside of the material box 3 from the feed hopper 2 and is accumulated in a corner of the material box 3. Through the work of the vibration motor 501, the vibration plate 502 is driven to vibrate the material box 3, thereby making the material box 3 vibrate. The soil vibration inside the material box 3 causes the soil to spread and spread out inside the material box 3, and the connecting nose 601 fixedly connected to the vibration plate 502 squeezes the first compression spring 603, thereby achieving the purpose of cushioning;

When the soil is flattened inside the material box 3, we start the water pump 102, and the water inlet end of the water pump 102 is fixedly connected to the water pipe of the external water tank to supply water to the water inlet pipe 101. The water inside the water inlet pipe 101 passes through the water spray head 103. The soil inside the material box 3 is sprayed to simulate the corrosion of soil by rainwater on rainy days;

When the water pump 102 continues to work with a small power, the water inside the water inlet pipe 101 is small at this time, so that when the water inside the water inlet pipe 101 circulates, only a very small part of the water enters the inside of the inclined pipe 1102 and flows smoothly. The inclined tube 1102 falls inside the water storage tube 1104. As time goes by, the water inside the water storage tube 1104 will increase, thereby increasing the weight of the water storage tube 1104. The water storage tube 1104 will squeeze the main extrusion block 1106 and the slave The extrusion blocks 1107 are staggered, so that the main extrusion block 1106 moves downward inside the cylinder 1101, and the slave extrusion block 1107 moves horizontally inside the horizontal tube 1103. As the weight of the water storage tube 1104 increases, it will push The closing plate 1109 at one end of the extrusion block 1107 enters the inside of the water inlet pipe 101, thereby reducing the inner diameter of the water pipe inside the water inlet pipe 101. When the main extrusion block 1106 comes into contact with the micro switch 12, the water pump 102 stops working. At this time The closing plate 1109 completely blocks the inside of the water inlet pipe 101, so that water cannot flow from the water inlet pipe 101 to the sprinkler head 103, thereby simulating the process of a rainy day in reality, where the amount of rainwater changes from large to small, and finally to none;

At the same time, water will penetrate into the soil, and the water will be filtered through the filter plate 7, thereby preventing the soil from being lost along with the water. Rainwater will fall on the sponge layer 802 through the filter plate 7, and the sponge layer 802 will The water droplets absorb, thus simulating the diversion effect of soil on water in real life, thereby better simulating the state of soil in real life and reducing the influence of external factors, so that the data collected after the experiment is more authentic;

When the water pump 102 stops working, the fluorescent lamp 13 starts to work. At this time, the fluorescent lamp 13 simulates normal sunlight, and in the process, the electric push rod 901 contracts, so that the central axis rod 902 drives the horizontal bar 903 to move downward. During the downward movement of the rod 903, it will squeeze the extrusion plate 906, causing the extrusion plate 906 to move downward by squeezing the second compression spring 907. During the downward movement of the extrusion plate 906 , the sponge layer 802 will be squeezed, so that the water inside the sponge layer 802 is squeezed out, increasing the water absorption of the sponge layer 802, thereby simulating the phenomenon that the water inside the soil can continue to penetrate downward after the weather does not rain in reality. ;

During the above process, the power supply 16 continuously energizes the positive terminal 14 and the negative terminal 15, thereby accelerating the metal corrosion rate inside the metal box 4, thereby ensuring the complete conduct of the experiment.
