[0018] This embodiment provides an automatic diagnostic system for the airtightness of grain pest and insect gas pipelines, including an in-warehouse gas pipeline system and an insect gas detection system, wherein...

Each air passage includes an internal air collection pipe, an internal air outlet, a control ball valve, and an air pipe connector. The internal air collection pipe, internal air outlet, control ball valve, and air pipe connector are connected sequentially.

The gas detection channel includes a gas detection solenoid valve, a first filter, a displacement solenoid valve, a second filter, a one-way throttle valve, a carbon dioxide sensor, an oxygen sensor, a phosphine sensor, a diagnostic solenoid valve, and a small air pump. One side of the insect detection ball valve is connected to the first T-shaped tee via a pipeline, and the other side of the insect detection ball valve is sequentially connected to the insect counting module, the insect collection bottle, and the air pump via pipelines. The output end of the air pump is connected to the internal space. One side of the first filter is connected to the first T-shaped tee via a pipeline, and the other side of the first filter is connected to the gas measuring solenoid valve. One side of the second filter is connected to the outside via a pipeline, and the other side of the second filter is connected to the displacement solenoid valve. The gas measuring solenoid valve and the displacement solenoid valve are connected to the second T-shaped tee. The other end of the second T-shaped tee is connected in sequence to a one-way throttle valve, a carbon dioxide sensor, an oxygen sensor, a phosphine sensor, a diagnostic solenoid valve, and a small air pump. The output end of the small air pump is connected to the outside.

[0021] This utility model enables real-time detection of gas, pests, and airtightness in grain depots and silos. The controller integrates the system to detect the airtightness of each gas pipeline and perform self-diagnosis, reporting the results to management personnel. If any leaks are detected, necessary measures are taken promptly, increasing the safety of staff and reducing economic losses.

[0022] Working principle:

[0023] (1) Insect detection function: After the insect detection ball valve is opened, the gas detection solenoid valve is closed, the displacement solenoid valve is closed, the atmospheric pump is opened, and the selected ball valves are opened in sequence, the insect detection function of each selected pipeline is performed in sequence, and the pressure gauge value is read / displayed.

[0024] (2) Gas measurement function:

[0025] A) The insect detection ball valve and the replacement solenoid valve are closed. The gas detection solenoid valve, the diagnostic solenoid valve, and each selector ball valve are opened in sequence. After the small air pump is turned on for 30 seconds, the gas detection data of each selector pipeline is read and the pressure gauge value is read / displayed.

[0026] B) Replacement Function: The replacement solenoid valve and diagnostic solenoid valve open, while other ball valves and solenoid valves close. The small air pump operates for 30 seconds to perform a fresh air replacement function for the three gas sensors. The replacement function is only performed after the pH3 test is completed.

[0027] (3) Air tightness diagnostic function:

[0028] A) All selector ball valves, insect detection ball valves, and displacement solenoid valves are closed;

[0029] B) After the gas measuring solenoid valve and diagnostic solenoid valve are opened and the small air pump has been running for about 30 seconds, wait for the pressure gauge reading to stabilize.

[0030] C) Diagnose the problem: 2 seconds after the solenoid valve closes, the small air pump shuts down, and read the pressure gauge value A1.

[0031] D) After 30 seconds, read the pressure gauge value A2;

[0032] E) Judgment: 100Pa≥A2-A1≥0 indicates that the airtightness performance is qualified.

[0033] When A2-A1≥100Pa, the airtightness performance is unqualified.

[0034] (4) Leak test: If the air tightness performance is not up to standard, a leak test can be performed.

[0035] A) Automatic Leak Detection Test: With the displacement solenoid valve continuously closed and the small air pump continuously operating, the diagnostic solenoid valve is opened. After closing the gas testing solenoid valve, the pressure gauge reading remains unchanged, indicating that there is no leak at the front end of the gas testing solenoid valve. After reopening the gas testing solenoid valve and closing the diagnostic solenoid valve, the pressure gauge reading changes, indicating that there is a leak in the gas testing sensor.

[0036] B) Manual leak detection test: If a leak is found in a certain section of the trachea after step A, you can block a certain opening in that section of the trachea with your hand and continue to look for the leak.

[0037] (5) After all the above functions are completed, all ball valves, solenoid valves, air pumps and small air pumps will be restored to the power-off state.

[0038] This invention enables real-time gas detection inside a grain silo, pest detection, counting, statistical early warning, and gas pressure detection and diagnosis. The control center independently controls each control ball valve, allowing selective detection of 15 gas channels within the silo. All 15 gas channels are connected to a main gas pipe connector via gas pipe connectors, and further connected to a first T-shaped tee and an electronic pressure gauge. The first T-shaped tee directs gas into the pest and gas detection channels. The electronic pressure gauge performs real-time pressure monitoring, enabling airtightness detection and diagnosis of each gas channel. The pest detection channel enables pest counting detection, with a large atmospheric pump returning the gas to the silo (used during fumigation and controlled atmosphere processing). The gas detection channel detects carbon dioxide, oxygen, and phosphine in each gas channel within the silo. Each electromagnetic ball valve can be controlled by the controller system to open any gas channel, completing pest detection, gas detection, and airtightness detection and diagnosis of each channel.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
