[0053] The working principle and use process of the present invention are as follows: first, a concrete block cast from rice husk concrete is placed on the top of the placement slot plate 301, and then the limiting slider 311 is pulled to make the limiting slider 311 overcome the elastic force of the supporting spring 310, so that the limiting slider 311 slides upward on the outside of the limiting slide rod 309, so as to drive the bottom fixing frame 312 to slide out from the inner side of the limiting slot 307, release the limiting effect of the bottom fixing frame 312 on the sliding sleeve 305, and then slide the sliding sleeve 305 to clamp the rice husk concrete block at the top of the placement slot plate 301, and then release the limiting slider 311 to reinsert the bottom fixing frame 312 into the inner side of the limiting slot 307 , thereby clamping the rice husk concrete block, and then turning on the torque motor 303 to drive the winding rod 302 to rotate, so that the winding rod 302 starts to wind up and tighten the steel cable 304, and then pulls the placement slot plate 301 to move to the inside of the test chamber 202, and by winding up and tightening the steel cable 304, the rice husk concrete block can be quickly and labor-savingly moved to the inside of the test chamber 202, so that researchers can quickly and labor-savingly move rice husk concrete blocks of different weights and specifications to the inside of the test device, thereby improving the test efficiency, and the sliding of the clamping plate 306 can clamp and fix rice husk concrete blocks of different specifications, further increasing the use range of the detection device;

[0054] Next, the tester rotates the turntable 215 to drive the sealing threaded rod 214 to rotate inside the threaded groove barrel 212, thereby continuously driving the sealing opening and closing plate 213 to move toward the test box 1. After the sealing threaded rod 214 is fully tightened, the test box 1 is sealed. At this time, the sealing cover 203 is opened, and then a large amount of ice cubes are put into the inner side of the ice adding groove 201, and then the sealing cover 203 is closed. At this time, the temperature inside the test chamber 202 will continue to drop under the action of the temperature equalizing tank 206, thereby testing the antifreeze performance of the rice husk concrete. As time goes by, the ice will melt and produce a lot of ice water. At this time, the ice water will be collected into the inner side of the water tank 207 through the bottom guide groove 208. Then, in a closed environment, the concrete slab inside the test chamber 202 will be in a relatively humid environment. At this time, the anti-alkali ability of the concrete block will be tested by connecting the test chamber 202 and the water tank 207 through the anti-alkali water outlet 211. At this time, the anti-alkali degree of the concrete can be observed through the double-layer glass 218, so as to obtain the anti-alkali ability of the rice husk concrete block. The anti-alkali capacity data is obtained by finally loosening the sealing threaded rod 214, thereby moving the sealing opening and closing plate 213 to a certain distance on one side of the rice husk concrete block. At this time, the mounting plate 216 is started, and the mounting plate 216 will spray the water inside the water tank 207 to the rice husk concrete block through the water outlet hose 210 and the nozzle 220. As the distance between the sealing opening and closing plate 213 and the concrete block changes, the water permeability data of multiple concrete blocks can be obtained. By putting a large amount of ice cubes into the inner side of the ice adding tank 201, the anti-freezing performance of the rice husk concrete is tested, and then the anti-alkali capacity of the concrete block is tested by connecting the test chamber 202 and the water tank 207 through the anti-alkali water outlet tank 211. Then, by changing the distance between the sealing opening and closing plate 213 and the rice husk concrete block and the spraying of the nozzle 220, the water permeability of the concrete block is further tested. Thus, the device tests multiple indicators of the durability of the concrete, improves the test efficiency, reduces the unnecessary movement of the concrete block, further saves the test time, and also saves a lot of resources required for the test, thereby improving the comprehensive use efficiency of the device;

[0055] Finally, the rice husk concrete block is moved from the inner side of the test chamber 202 to the bottom of the spray barrel 402 by placing the groove plate 301. At this time, a large amount of yellow sand is put into the inner side of the sand barrel 406, and then the solenoid valve 404 is opened, so that the external high-pressure gas will be blown to the power turbine 411 through the high-pressure air intake pipe 403 and then drive the power turbine 411 to rotate, thereby driving the rotating rod 409 and the auger blade 410 to rotate, so as to guide the yellow sand inside the sand barrel 406 to the inner side of the spray barrel 402, and then blown to the rice husk concrete block with the external high-pressure gas to simulate the erosion of the rice husk concrete block by blowing sand, so as to detect the weathering resistance of the rice husk concrete block, further increase the validity and integrity of the durability test results of the rice husk concrete block, thereby improving the diversity of the test data, which is conducive to people's further understanding of the various data of rice husk concrete, thereby helping people to further make up for the poor performance of rice husk concrete and further improve the overall quality of rice husk concrete.
