Description

Technical Field

[0001] The present invention relates to the technical field of foundation soil detection devices, in particular to an indoor foundation soil detection device. Background Art

[0002] The foundation refers to the soil or rock mass that supports the foundation of a building. The soil layers used as building foundations are divided into rock, gravel soil, sand, silt, clay soil and artificial fill. There are two types of foundations: natural foundations and artificial foundations (composite foundations). Natural foundations are natural soil layers that do not require human reinforcement.

[0003] For example, Chinese patent publication number CN216900531U discloses a foundation soil erosion detection device comprising a loosening assembly mounted on a housing for loosening soil within the housing, a crushing assembly rotatably connected to the housing, and a detection assembly connected to the housing. By adding foundation soil to the housing and activating the loosening assembly, the loosening assembly can loosen the foundation soil. The loosening assembly, when rotating, can drive the crushing assembly to rotate within the housing via the connecting assembly.

[0004] However, the above solution has the following shortcomings: in the above patent, the foundation soil is loosened by the loosening component, and the crushing component is driven to rotate in the body by the connecting component, and then the foundation soil in the body can be effectively loosened under the action of the loosening component and the crushing component, and the detection component detects the foundation soil. However, in the actual operation process, since the device is reused and the soil properties in each environment to be detected are also different, when the soil of another environment remains in the device, it may be mixed with the new soil during the mixing process, resulting in inaccurate data during the test process.

[0034] A lifting plate 5 is movably connected to the inside of the detection box 1. The lower end of the lifting plate 5 is fixedly connected to a support spring 12. The lower end of the support spring 12 is fixedly connected to the inside of the detection box 1. The connecting column 15 is movably sleeved on the inside of the lifting plate 5.

[0035] A feeding mechanism is provided in the feeding trough 10, through which the crushed foundation soil is transported into the feeding trough 10. Two blocking mechanisms are provided in the connecting trough 33. When the lifting plate 5 moves upward, the two blocking mechanisms block the connecting trough 33 to prevent the soil on the upper end of the lifting plate 5 from entering the inner bottom of the detection box 1 through the connecting trough 33. A foundation soil collecting mechanism is movably installed on the upper end of the detection box 1 through a buckle. The foundation soil collecting mechanism is used to collect the foundation soil in the area to be tested.

When the connecting blocks 16 are rolled up, the protruding portion of the connecting block 16 farthest from the connecting post 15 stops rolling when it moves to the position of the clearance groove, preventing the connecting blocks 16 from being completely received into the receiving cavity 13, which would prevent the connecting blocks 16 from being unfolded.

[0038] The feeding mechanism includes a connecting roller 8, one end of the connecting roller 8 is movably connected to the feeding groove 10, a plurality of grooves 17 are provided on the outside of the connecting roller 8, a push rod 19 is movably connected in the groove 17, and the opposite ends of the plurality of push rods 19 are arranged in an arc shape and extend into the inside of the connecting roller 8.

By squeezing the push rod 19, the foundation soil remaining in the groove 17 is pushed out. When the push rod 19 is no longer in contact with the squeezing rod 20, the push rod 19 returns to its original position under the elastic force of the return spring 18;

[0039] One end of the connecting roller 8 extends into the external environment and is fixedly connected to the pulley 26. Several pulleys 26 are connected to each other by belts 25.

The blocking mechanism includes a T-shaped blocking plate 32. One end of the T-shaped blocking plate 32 extends into the connecting groove 33, and the other end is slidably connected to the sliding cavity 31. The sliding cavity 31 is opened in the lifting plate 5. A connecting spring 34 is fixedly connected to the sliding cavity 31. The other end of the connecting spring 34 is fixedly connected to the T-shaped blocking plate 32. When the lifting plate 5 moves downward to the inner bottom of the detection box 1, the T-shaped blocking plate 32 will be squeezed by the connecting roller 8 to move into the sliding cavity 31, and the T-shaped blocking plate 32 contacts the surface of the connecting roller 8, so that the excess foundation soil on the surface of the connecting roller 8 is scraped off;

[0040] The foundation soil collection mechanism includes a collection box 2, and a baffle 3 is movably connected in the collection box 2. The foundation soil of the area to be tested can be stored through the collection box 2. After the storage is completed, the baffle 3 is inserted into the collection box 2. The adjustable transmission mechanism includes an inner and outer gear ring 30, such as Figure 9As shown, the inner side of the inner and outer gear rings 30 is provided with a plurality of teeth, and the outer side is provided with a tooth groove. Through the setting of the tooth groove, the inner and outer gear rings 30 can drive the transmission gear 35 to move when moving. The inner and outer gear rings 30 are arranged in the connecting cavity 36. The inner and outer sides of the inner and outer gear rings 30 are provided with a plurality of teeth. The outer sides of the inner and outer gear rings 30 are meshed with the transmission gear 35. The transmission gear 35 is slidably connected to the outer side of the square rod 38. The upper end of the square rod 38 is movably connected to the connecting cavity 36, and the lower end is fixedly connected to the output end of the transmission motor 28. The transmission motor 28 is fixedly connected to the detection box 1. A plurality of electric telescopic rods 37 are fixedly connected to the lower end of the connecting cavity 36. The upper end of the electric telescopic rod 37 is movably connected to the lower end of the inner and outer gear rings 30.

[0041] The sample pressing detection mechanism includes an experimental chamber 9, which is opened in the detection box 1. A pressure plate 7 is slidably connected in the experimental chamber 9, and the pressure plate 7 is fixedly connected to the output end of the telescopic cylinder 6. The telescopic cylinder 6 is fixedly installed in the detection box 1. A blocking plate 11 is movably installed at one end of the experimental chamber 9, and an observation window 29 is fixedly installed on one side of the detection box 1, and a scale is provided on the outside of the observation window 29.

[0042] Working principle: when in use, the foundation soil of the area to be tested can be stored through the collection box 2. After the storage is completed, the baffle 3 is inserted into the collection box 2, and the collection box 2 containing the foundation soil is carried to the laboratory. When the foundation soil needs to be tested, the collection box 2 is installed on the upper end of the detection box 1 through the buckle. During the installation process, the lower end of the collection box 2 will squeeze the connecting rod 4, and at this time the lifting plate 5 will move downward. When the installation is completed, the lifting plate 5 moves to the inner bottom of the detection box 1;

[0043] Open the two electric telescopic rods 37 to drive the inner and outer gear rings 30 to move downward, so that they mesh with the connecting gear 24. During the movement of the inner and outer gear rings 30, the transmission gear 35 will follow and move. Turn on the transmission motor 28 to drive the square rod 38 to start rotating. The rotation of the square rod 38 drives the transmission gear 35 to start rotating. Since the transmission gear 35 is engaged with the inner and outer gear rings 30, the inner and outer gear rings 30 will rotate with the transmission gear 35. At this time, the connecting gear 24 will start to rotate clockwise. Through the clockwise rotation of the connecting gear 24, Several connecting blocks 16 are extended into the external environment. When all of them are extended, the transmission motor 28 is turned off. By controlling the electric telescopic rod 37 to move upward, the inner and outer gear rings 30 are driven to engage with the gear ring 23. The transmission motor 28 drives the connecting column 15 to rotate clockwise. Under the obstruction of the limit plate 21, the several connecting blocks 16 moving in the clockwise direction will not bend. The baffle 3 is pulled out. At this time, the foundation soil in the collection box 2 will enter the detection box 1, and the foundation soil is broken up by the several clockwise rotating connecting blocks 16.

[0044] Turn on the connecting motor 27 to drive the pulley 26 connected to it to rotate. Under the connection of the belt 25, several pulleys 26 rotate synchronously. At this time, the connecting roller 8 will start to rotate, and the crushed foundation soil will enter the groove 17. At this time, under the rotation of the connecting roller 8, the foundation soil in the groove 17 will pass through the feeding trough 10 and enter the experimental chamber 9. Under the limit of the squeezing rod 20, the push rod 19 moved to the lower side will be continuously squeezed. By squeezing the push rod 19, the foundation soil remaining in the groove 17 is pushed out. When the push rod 19 is no longer in contact with the squeezing rod 20, the push rod 19 returns to its original position under the elastic force of the return spring 18.

[0045] After the foundation soil has filled the experimental cavity 9, the connecting motor 27 is turned off to stop the connecting roller 8 from rotating, and the telescopic cylinder 6 is opened to drive the pressing plate 7 to move. The foundation soil in the experimental cavity 9 is squeezed by the moving pressing plate 7. The compression distance of the foundation soil sample can be observed through the observation window 29 and the scale on its surface. By setting up multiple groups of experiments, the erosion degree of different foundation soils can be tested.

[0046] After the inspection is completed, the foundation soil after the experiment can be taken out by opening the blocking plate 11. According to the above method, the winding column 14 is rotated counterclockwise to reel several connecting blocks 16 into the storage cavity 13, and the collection box 2 is removed. At this time, under the elastic force of the support spring 12, the lifting plate 5 moves upward to clean the connecting column 15 and the inside of the inspection box 1. At the same time, when the T-shaped blocking plate 32 no longer contacts the connecting roller 8, under the elastic force of the connecting spring 34, the two T-shaped blocking plates 32 block the connecting groove 33 to prevent the hanging soil from falling into the bottom of the inspection box 1 through the connecting groove 33. When the lifting plate 5 moves to the upper protrusion of the connecting column 15, the lifting plate 5 stops moving, and the operator can clean the surface of the lifting plate 5.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
