Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0035] As Figures 1-4 shown, the present invention provides an atmospheric corrosion monitoring device, and the device includes a bracket 1, a lower detection mechanism, and an upper detection mechanism mounted on the bracket 1. Among them,

[0036] The lower detection mechanism includes a measurement frame 2, a detection block 3, and a moving mechanism. Among them, the moving mechanism is disposed on the measurement frame 2 and is used to drive the detection block 3 to move up and down; a first measurement plate 4 is provided on the measurement frame 2;

[0037] The upper detection mechanism is used to drive the detection block 3 to move up, and measure the pressure of the first measurement plate 4 after being corroded and before being squeezed and broken by the moving mechanism; among them,

[0038] The upper detection mechanism includes a gas frame 5, a pressing mechanism and a film stopper 31 arranged in the gas frame 5. Among them, the opening of the gas frame 5 is connected to the top of the measurement frame 2. The pressing mechanism is used to press the first measurement plate 4, and a corrosive gas 6 is arranged in the gas frame 5.

[0039] A detailed description will be given below.

[0040] In this embodiment, the bracket 1 includes a first frame 7 and a support frame. Among them,

[0041] The support frame includes a support plate 8 and a support rod 9 connected to the bottom of the support plate 8. The bottom of the support rod 9 is fixed to the bottom inside the first frame 7, and the moving mechanism is arranged on the support plate 8. Among them, the moving mechanism includes a cylinder seat 20 and a second hydraulic cylinder 21. Among them,

[0042] The cylinder seat 20 is fixed on the support plate 8, the second hydraulic cylinder 21 is installed on the cylinder seat 20, and the output end of the second hydraulic cylinder 21 is connected to the detection block 3. Therefore, through the moving mechanism, the left - right movement of the detection block 3 can be controlled. Since the moving mechanism can also drive the detection block 3 to move up and down, a chute plate 33 can be arranged at the output end of the second hydraulic cylinder 21. A chute is arranged on the chute plate 33. The detection block 3 can move in the up - down direction through a slide rod (the slide rod is installed in the chute) installed on the detection block 3. Thus, the detection block 3 can move up and down under the drive of the moving mechanism.

[0043] In this embodiment, the measurement frame 2 includes a second frame 10 and a frame cover 11. Among them,

[0044] The opening of the second frame 10 faces upward, and the opening of the frame cover 11 faces downward;

[0045] The bottom of the second frame 10 is connected to the first frame 7, and one side wall of the second frame 10 is connected to the support plate 8;

[0046] The top of the frame cover 11 is connected to the first frame 7. An inner hole is opened on the frame cover 11, and the first measurement plate 4 is installed in the inner hole. The first measurement plate 4 can be used as a simulated corrosion sample of a conventional measurement plate.

[0047] In this embodiment, the top of the detection block 3 can contact the bottom of the frame cover 11. Among them,

[0048] A first notch is arranged on the upper surface of the detection block 3. The first notch is filled with first sand 18. The first notch is located directly below the first measurement plate 4. The other end of the detection block 3 is connected to the moving mechanism.

[0049] In this embodiment, the baffle film 31 divides the interior of the gas frame 5 into a first cavity 22 and a second cavity 23, where,

[0050] the second cavity 23 is located below the first cavity 22 and above the first measurement plate 4; the second cavity 23 is filled with a corrosive gas 6, and the corrosive gas 6 in this embodiment is the waste gas discharged industrially. The waste gas discharged industrially can accelerate the corrosion rate of metal objects. In this embodiment, when the first measurement plate 4 is in the inner hole of the frame cover 11, it can contact the corrosive gas 6 in the second cavity 23 and thus be corroded under the action of the corrosive gas 6.

[0051] In addition, in this embodiment, a connecting pipe 27 is provided on the side wall of the gas frame 5. One end of the connecting pipe 27 communicates with the second cavity 23, and the other end of the connecting pipe 27 passes through the gas frame 5 and is connected to a pump body 28. The pump body 28 is fixed on the top of the mounting frame one 7, and the pump body 28 is communicated with the gas tank 29 on the frame one 7 through an air outlet pipe.

[0052] In this embodiment, the extrusion mechanism is arranged in the first cavity 22, where,

[0053] the extrusion mechanism includes a third hydraulic cylinder 24. The third hydraulic cylinder 24 is located in the first cavity 22 and connected to the top inside the gas frame 5. A pressing plate 25 is provided at the bottom of the third hydraulic cylinder 24, and a heating wire is provided inside the pressing plate 25. After the specified time for the first time, the corrosive gas 6 in the second cavity 23 can be pumped out through the pump body 28.

[0054] After the corrosive gas 6 is pumped out, by controlling the third hydraulic cylinder 24, the pressing plate 25 moves downward, and the heating wire in the pressing plate 25 is heated (the pressing plate 25 is made of a metal material with better heat transfer effect), so that the pressing plate 25 is heated and can penetrate through the baffle film 31 (the baffle film 31 is made of a thin film material), thereby squeezing the first measurement plate 4. Among them, the baffle film 31 only plays a role in protecting the pressing plate 25 from being corroded by the corrosive gas 6 after the specified time for the first time (because the specified time for the first time is relatively long, so the pressing plate 2 needs to be protected).

[0055] In this embodiment, the moving mechanism includes a connecting plate 12, a first hydraulic cylinder 13 and four moving plates 14. Among them, the first hydraulic cylinder 13 is installed at the bottom inside the frame two 10 (a buffer pipe 34 is provided at the bottom inside the frame two 10, a pressure sensor is provided inside the buffer pipe 34, a spring is provided at the bottom of the first hydraulic cylinder 13, and the bottom of the first hydraulic cylinder 13 is inserted into the buffer pipe 34), the connecting plate 12 is connected to the output end of the first hydraulic cylinder 13, and the four moving plates 14 are connected to the four side walls of the connecting plate 12.

[0056] The frame two 10 has four side walls, each side wall is provided with an inner groove 15, and a pressure sensor 16 is installed in each inner groove 15; the bottoms of the four movable plates 14 are respectively inserted into the four inner grooves 15, and a spring 17 is provided at the bottom of each movable plate 14; the bottom of the detection block 3 can contact the bottoms of the four movable plates 14. Therefore, when the first measuring plate 4 is squeezed, the force when the first measuring plate 4 is squeezed can be obtained through the five pressure sensors. If at this time, the first measuring plate 4 is broken (after being broken, the first measuring plate 4 broken into two sections will be pressed into the first sand 18), then according to the thickness of the first measuring plate 4 recorded in advance, it can be known how much is the maximum pressure that the first measuring plate 4 can withstand before being broken after the first corrosion at the specified time, which is convenient for the subsequent targeted design of the first measuring plate 4 (as for how to design, it is not within the protection scope of the present invention and will not be elaborated again).

[0057] In this embodiment, a second notch is further provided on the upper surface of the detection block 3, the second notch is filled with second sand 19, the second notch is located inside the bracket 1, and a second measuring plate 30 is further provided on the detection block 3, and the second measuring plate 30 is located above the second notch.

[0058] After the first measuring plate 4 is broken, by starting the first hydraulic cylinder 13, the entire detection block 3 descends under the action of gravity, the first measuring plate 4 disengages from the inner hole of the frame cover 11, and then the second hydraulic cylinder 21 is started, so that the entire detection block 3 can move to the left. When the second measuring plate 30 can align with the inner hole of the frame cover 11, then the first hydraulic cylinder 13 is started. After the second measuring plate 30 is inserted into the inner hole of the frame cover 11, the pump body 28 is controlled to re-inject the corrosive gas 6 in the gas tank 29 into the second cavity 23, and then the corrosion experiment of the first measuring plate 4 is repeated. Since part of the sulfate-reducing bacteria in the corrosive gas 6 has been consumed, therefore, after the specified time of the second time (the specified time of the second time is greater than the specified time of the first time), the above corrosion experiment of the first measuring plate 4 is repeated, so that it can be obtained how much is the maximum pressure that the second measuring plate 30 can withstand before being broken after the second corrosion at the specified time of the second measuring plate 30. It should be noted that by knowing how much is the maximum pressure that the second measuring plate 30 can withstand before being broken, it can be estimated how much is the bearing capacity of the double-layer measuring plate buried underground after being corroded by sulfate-reducing bacteria in the soil.

[0059] In addition, in this embodiment, an air inlet pipe 26 is provided on the side wall of the gas frame 5, the air inlet pipe 26 is communicated with the second cavity 23, the air inlet pipe 26 is used for introducing the corrosive gas 6, and an air inlet cover 32 is provided on the air inlet pipe 26. Through the air inlet pipe 26, the corrosive gas 6 can be injected into the second cavity 23.
