Description

Technical Field

[0001] This utility model relates to the field of electrical corrosion resistance testing technology, and in particular to a testing box for the corrosion resistance performance of electrical appliances in warehouses. Background Technology

[0002] Grain fumigation is a crucial pest control procedure in grain storage. It involves burying specific chemicals to generate highly toxic gases that kill pests. When pest infestations in grains (including finished grains, raw grains, oilseeds, dried sweet potatoes, and seed grains) reach a certain level, a certain amount of aluminum phosphide is buried in the grain pile under sealed conditions. This phosphide absorbs moisture from the gaps in the grain pile and the grain itself, causing a chemical reaction that releases highly toxic phosphine gas, effectively killing various pests and their eggs. Grain storage warehouses are typically equipped with electrical systems to automate operations. However, phosphine gas is corrosive to these electrical components. To ensure stable operation, the purchased electrical equipment needs to undergo phosphine gas corrosion resistance testing. Existing corrosion resistance testing equipment struggles to maintain stable phosphine gas concentrations and control their concentration, making it difficult to determine the accuracy of the test results. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of some existing corrosion resistance testing equipment, which makes it difficult to ensure the stability of phosphine gas concentration and control the concentration of phosphine gas when testing its corrosion resistance, thus making it difficult to determine the accuracy of experimental results. This invention provides a corrosion resistance testing box for warehouse electrical appliances.

[0004] The purpose of this utility model is achieved through the following technical solution: a warehouse electrical corrosion resistance testing box, including a box body and a box cover, the box cover being detachably installed on the box body, multiple sets of drug decomposition tanks being installed inside the box body, multiple sets of equidistantly arrayed volatilization holes being opened on the drug decomposition tanks, a pneumatic ball valve being installed on the box cover, the inlet end of the pneumatic ball valve being equipped with a drug inlet, the outlet end of the pneumatic ball valve extending into the box body and corresponding to the inlet end of the drug decomposition tank, by setting the drug inlet and the pneumatic ball valve, it is convenient to add drugs into the drug decomposition tanks, when the display shows that the phosphine gas concentration inside the box is lower than the set standard, drugs can be added into the drug decomposition tanks through the drug inlet and the pneumatic ball valve to control the phosphine gas concentration inside the box to maintain it within a stable range, thereby achieving control of the phosphine gas concentration inside the box and ensuring the accuracy of subsequent test results;

[0005] The enclosure is equipped with an industrial control panel and a junction box for the electrical appliance under test. The junction box for the electrical appliance under test has multiple sets of terminals located inside the enclosure. The industrial control panel is equipped with a power on / off numbered switch connected to the junction box for the electrical appliance under test. The power on / off numbered switch is used to control the opening and closing of the terminals on the junction box for the electrical appliance under test. The industrial control panel is equipped with a power supply connected to the power on / off numbered switch. By setting the power on / off numbered switch, the opening and closing of the terminals on the junction box for the electrical appliance under test can be controlled from outside the enclosure, improving the convenience of operation.

[0006] The enclosure contains a phosphine gas concentration sensor, and the control panel has a display screen connected to the phosphine gas concentration sensor. The display screen is used to show the gas concentration data monitored by the phosphine gas concentration sensor.

[0007] A further technical solution is to install multiple sets of equally spaced mounting slots on the inner side wall of the chamber. The drug decomposition pool can be detachably snapped into the mounting slot. By setting the mounting slot, it is easy to remove the drug decomposition pool from the chamber, and it is convenient to clean up the waste in the drug decomposition pool after the test.

[0008] A further technical solution is to install sealing strips on the inner wall of the enclosure that correspond to the enclosure lid. By setting the sealing strips, the sealing effect at the connection between the enclosure and the lid can be improved, preventing phosphine gas from escaping through the connection between the enclosure and the lid and causing environmental pollution, thus ensuring the health of the staff.

[0009] A further technical solution is that the cover is connected to the box body by a snap fastener. The snap fastener makes it easy to install the cover onto the box body, making the cover easy to remove and install, and making it easy to place the electrical appliance to be tested into the box body.

[0010] A further technical solution is to have a shelf inside the enclosure for placing the electrical appliance under test. The inner wall of the enclosure is equipped with a locking block, and the shelf is secured to the inner wall of the enclosure by the locking block. By setting the shelf and the locking block in cooperation, the number of shelf units installed can be easily adjusted according to the number of electrical appliances under test. When the volume of the electrical appliance under test is large, some shelf units can be removed to meet the usage requirements, thereby improving the applicability of the enclosure.

[0011] A further technical solution is to have equidistant ventilation holes on the shelf. By setting ventilation holes, the flow of phosphine gas in the chamber can be improved, thereby ensuring the accuracy of the experimental results.

[0012] A further technical solution is to install a transparent observation window on the side of the enclosure, which allows for easy observation of the operation of the electrical appliance under test inside the enclosure.

[0013] A further technical solution is to install self-locking casters on the bottom of the box. By setting self-locking casters, the mobility of the box can be improved, making the box easy to move and improving the convenience of use.

[0014] A further technical solution is to install an air pump on the chamber, with both the air inlet and outlet located inside the chamber. The air inlet is located at the bottom of the chamber, and the air outlet is located at the top. By setting up the air pump, the phosphine gas inside the chamber can be circulated, thereby ensuring the uniform distribution of the phosphine gas inside the chamber and guaranteeing the accuracy of the experimental results.

[0015] This invention has the following advantages: By setting a dosing port and a pneumatic ball valve, it is easy to add drugs to the drug decomposition tank. When the display shows that the concentration of phosphine gas in the tank is lower than the set standard, drugs can be added to the tank through the dosing port and the pneumatic ball valve to control the concentration of phosphine gas in the tank and maintain it within a stable range. This achieves control over the concentration of phosphine gas in the tank, ensuring the accuracy of subsequent test results. The sealing strip improves the sealing effect at the connection between the tank body and the lid, preventing phosphine gas from escaping through the connection and causing environmental pollution, thus protecting the health of the staff.
