[0018] The present invention provides a wood corrosion resistance detection device based on wood science and engineering through improvement, which has the following improvements and advantages compared with the prior art:

[0019] First, the present invention sets a transmission mechanism. When the first telescopic rod is started to lift the wood, as the transmission seat and the fixed plate move upward, the first gear is meshed with the transmission rack, and the first gear will then rotate on the transmission rack. The first gear will then drive the transmission shaft to rotate, and then can drive another transmission shaft to rotate through the transmission bevel gear, and the transmission shaft will drive the second gear to rotate, the second gear is meshed with the third gear, and the third gear will be driven by the second gear to rotate, and the third gear will drive the fourth gear to rotate. The fourth gear can drive the installation shaft to rotate through the transmission belt and another fourth gear, and the installation shaft can finally drive the fixed plate to rotate. The rotation of the fixed plate can make the wood rotate when it is removed from the solution, and then the solution remaining on the surface of the wood can be thrown off the wood through centrifugal force, so as to achieve the effect of facilitating the removal of the wood from the solution, and at the same time, the solution on the surface of the wood can be automatically cleaned off, which is convenient for subsequent observation.

[0020] Secondly, the present invention provides a fixing mechanism. When the wood needs to be fixed, the wood can be placed on the top of the fixing plate, and then the adjusting shaft is rotated. The adjusting shaft is threadedly connected to the two transmission blocks, which will cause the two transmission blocks to move closer to or away from each other, thereby driving the clamping blocks to clamp the wood, thereby achieving the effect of fixing wood of different sizes.

[0021] Thirdly, the present invention arranges a liquid replenishing mechanism. When the transmission seat moves upward, the transmission seat can drive the cross bar and the push rod to move upward. When the push rod moves to contact with the push rod, as the push rod continues to move, the push rod will be squeezed by the push rod, thereby driving the movable plate to move upward. When the movable plate moves upward, the lower liquid port will be opened. At this time, the solution above the movable plate will flow to the bottom of the liquid replenishing tank through the lower liquid port, and then flow to the inside of the detection box through the liquid replenishing pipe, thereby replenishing the solution inside the detection box, thereby achieving the effect of automatically replenishing the solution while checking the state of the wood.

[0022] Fourthly, in the present invention, through the setting of the drainage mechanism, when the wood is taken out of the solution and the solution inside the detection box is to be drained, the second telescopic rod can be started, and the second telescopic rod drives the lifting rod to move to the bottom of the flip rod. When the transmission seat moves upward, it will drive the lifting rod to move upward, and the lifting rod can then squeeze the flip rod. After the flip rod is subjected to force, the force applied to the flip rod is less than the force of the torsion spring shaft, which will drive the first sealing plate to move upward. At this time, the drainage port is opened, and the solution inside the detection box can be discharged to the inside of the collection box through the drainage port and the drainage pipe. When the first sealing plate moves to the top of the inside of the sealing seat, the force applied to the flip rod is The force of the lifting rod on the flip rod is smaller than the force of the torsion spring shaft but greater than the magnetic force of the positioning magnet. At this time, the first sealing plate will be reset downward to seal the drain port again. If the solution inside the first sealing plate does not need to be drained when the wood is taken out of the solution, it is only necessary to control the second telescopic rod so that the lifting rod does not contact the flip rod, thereby achieving the effect of automatically discharging and cleaning the used solution when the wood is taken out.

[0023] Fifth: In the present invention, when the solution inside the detection box is discharged into the interior of the collection box through the drain pipe, the second sealing plate will be impacted by the solution and then move downward inside the drain pipe. Subsequently, the solution can enter the interior of the collection box, and the filter can filter the solution, thereby filtering out the impurities inside the solution and collecting them inside the collection box. At the same time, the second sealing plate will squeeze the pressure rod while moving downward, and the pressure rod will then drive the filter to move downward and squeeze the reset spring at the same time. When the filtration is completed, the filter will reset under the elastic force of the reset spring, causing the filter to vibrate, thereby preventing the filter from being blocked by impurities.
