In this embodiment, the integrated base plate 160 can be placed without being locked and fixed on the base 110.
Referring to fig. 3, the horizontal table assembly 140 of the integrated environmental testing system 100 is a small horizontal table assembly disposed on the oil tank assembly 150, and includes a table body 142 and an oil protection frame 144. An oil protection frame 144 is disposed between the table body 142 and the tank assembly 150, and the oil protection frame 144 is used for preventing oil in the tank assembly from splashing out of the tank assembly. The table top main body 142 of the horizontal table top assembly 140 is provided with a groove for installing the sinking type limiting device, and the groove can be positioned and installed with the sinking type limiting device.
Referring to FIG. 4, the fuel tank assembly 150 of the environmental testing system 100 includes a tank 152 and a V-shaped rail 154 disposed within the tank 152. The V-shaped guide rails 154 guide the horizontal deck assembly 140 in a set path. The V-shaped guide 154 employs a large displacement guide to obtain a large displacement amount. Which is mounted within a tank 152 of the fuel tank assembly 150, and V-shaped rails 154 are used to support horizontal movement of the horizontal deck assembly 140. A limiting device 156 is fixed on the box body 152 of the oil tank assembly 150, the horizontal table top assembly 140 is fixed on the limiting device 156, and the limiting device 156 limits the movement of the horizontal table top assembly 140 along a set route.

The V-shaped guide rails 154, the stop 156, and the motorized table 120 cooperate to route the horizontal deck assembly 140.
Referring to fig. 4 and 5, a conflux gas blowing pipe 182 is disposed at a side of the tank body 152 of the oil tank assembly 150. The sink blow tube 182 blows moisture around the tank assembly 150 away from the tank assembly 150. The confluence blowing pipe 182 is fixed to the tank 152 of the tank assembly 150. The manifold air blowing pipe 182 includes a manifold body 182a, an air inlet joint 182b provided to the manifold body 182a, and an air blowing hole 182 c. Gas enters the manifold body from the gas inlet fitting 182b and is blown out of the gas blowing holes 182 c. Also, the opening direction of the blow hole 182c is directed away from the tank body 152 of the tank assembly 150 and toward the horizontal deck assembly 140. That is, the opening of the air blowing hole 182c is directed obliquely upward outside the case 152. This advantageously blows moisture from the environmental testing system 100 and prevents moisture from entering the tank 152 of the tank assembly 150.
Referring to fig. 6, the integrated environment test system 100 generates large displacement vibration through the large displacement electric vibration table 120, and transmits the large displacement vibration to the horizontal table assembly 140 mounted on the large displacement V-shaped guide rail 154, and thus to the test piece fixed on the horizontal table assembly 140, while the test piece is in the environment test box 170, thus forming a test system required for the integrated environment test of large displacement vibration and humidity.
When the integrated environmental test system 100 is in operation, the external power amplifier drives the moving coil of the electric oscillating table 120 to reciprocate, and the motion is transmitted to the horizontal table component 140 through the connector 130. The test piece mounted on the horizontal table assembly 140 may then be subjected to a vibration test. Meanwhile, the environmental test chamber 170 also performs a humidity test on the test piece existing in the closed space. During the experiment, sealed the assurance of carrying out the environmental test, this application adopts two rings of sealing washer to add one deck gas blowing device, and three-layer safeguard measure protects environmental test system and oil tank not destroyed, and concrete implementation is as follows.
A first seal 184 is disposed between the environmental test chamber 170 and the horizontal table assembly 140 of the integrated environmental test system 100. The first seal 184 forms a first layer of protection. Environmental test case 170 goes up to lock on can emboliaing the couple on the integration bottom plate 160 through hanging the knot, because the rigid connection is not enough to play sealed effect after the locking, two contact surfaces use first sealing washer 184 to obstruct external environment and internal environment this moment for the internal and external environment does not have temperature and humidity and exchanges the transmission, can guarantee that environmental test case 170 internal environment is experimental not disturbed by outside medium.
A second seal 186 is disposed between the horizontal deck assembly 140 and the integrated base plate 160 of the integrated environmental test system 100. The second seal 186 forms a second layer of protection. When the test is carried out, the upper end of the horizontal table top component 140 is tightly attached to the internal test environment of the environmental test box 170, the lower end of the horizontal table top component is the external environment, the condensed water generated by the temperature difference of humidity is attached to the back surface of the horizontal table top component 140, and the condensed water attached to the back surface of the horizontal table top component 140 along with the horizontal vibration is likely to flow into the oil tank component 150 to damage the internal environment of the oil tank component 150. Therefore, it is important to provide a second seal 186 between the horizontal deck assembly 140 and the integrated base plate 160. The upper end of the second sealing ring 186 is tightly attached to the lower end of the horizontal table component 140, so that when the horizontal table component 140 moves horizontally, the condensed water can be prevented from flowing into the tank body 152 of the oil tank component 150, and the function of keeping the internal environment of the oil tank component 150 stable within a required range is achieved.
When the second sealing ring 186 is damaged or the sealing effect of the second sealing ring 186 is weakened due to the long-time friction between the horizontal table component 140 and the second sealing ring 186, the flow converging and blowing pipe 182 is arranged for preventing the condensed water from flowing into the box body 152 along with the movement. Air supply continues to the air inlet connector 182b of the confluence air blowing pipe 182 through an external air source, and air is blown out along with the air blowing hole 182c of the confluence pipe body 182, so that condensed water is difficult to enter the tank body 152 of the oil tank assembly 150, the internal environment of the oil tank assembly 150 is well protected, and the comprehensive environment testing system 100 can effectively perform vibration and environment tests.
The comprehensive environment test system realizes large displacement test by adopting the matching of the large displacement electric vibration table, the large displacement V-shaped guide rail and other devices, adopts a tight three-layer protection sealing system for sealing so as to ensure the reliable and stable operation of the comprehensive environment test system, and integrally designs the electric vibration table and the environment test box so as to ensure compact integral structure and convenient installation and disassembly.
