Description

Technical Field

[0001] The utility model relates to the field of in-situ testing equipment, in particular to an in-situ testing device for geotechnical engineering investigation. Background Art

[0002] Nowadays, geotechnical engineering surveys require performance testing of geotechnical materials in their original positions or close to their original states. Generally, a piezometer is used for in-situ testing. Since it is not very convenient to move the piezometer during the test, it is installed on a mobile trolley or bracket, which is an in-situ testing device. However, during the test, rock and soil will stick to the piezometer, which will affect subsequent detection at other locations.

[0003] At present, most in-situ test devices are equipped with a cleaning structure to clean the surface of the instrument. However, the cleaning structure can only clean and remove dust from the upper surface of the instrument, but cannot clean the bottom of the instrument. In addition, the instrument is generally exposed to the outside and cannot be well hidden and protected. After a long time, a large amount of dust will accumulate on the surface of the instrument, thus affecting the results of the in-situ test.

[0004] Therefore, most of the existing in-situ testing devices are unable to hide and protect the instrument body, and are unable to completely clean the dust and dirt on the bottom of the instrument, resulting in certain deviations in the results during subsequent testing. Utility Model Content

[0008] Preferably, the upper surface of the base is provided with grooves corresponding to the driving gear and the driven gear, and a driving motor is fixedly installed on the upper end of the driving gear. When the driving motor is turned on, it drives the driving gear to rotate, and the rotation of the driving gear drives the driven gear to rotate. During the rotation of the driven gear, the cleaning sleeve will also rotate, so that the cleaning brush can clean the dirt on the surface of the side pressure device during the up and down movement of the side pressure device.

At the same time, after the main body of the barometer is retracted into the protective cover, the flushing component can flush the surface of the main body of the barometer from the bottom side, which can flush away the dirt on the bottom and surface of the main body of the barometer, and can prevent dirt from adhering to the bottom of the instrument, so as to avoid affecting the subsequent test results;

[0015] 2.

[0024] See also Figure 2-Figure 5 The flushing assembly 8 includes an electric push rod 801, which is fixedly mounted on the lower end surface of the support platform 3. A nozzle 802 is arranged at the movable end of the electric push rod 801, and evenly distributed water outlet holes 803 are opened on the surface of the nozzle 802.

After the solenoid valve is opened, the water in the water storage box 804 will flow into the nozzle 802 through the water outlet pipe 805, and then be ejected from the water outlet hole 803, thereby flushing the pressure relief device body 7.

[0025] See also Figure 1-Figure 4 The cleaning component 14 includes a driving gear 1402, a driven gear 1403 is arranged on the side of the driving gear 1402, the driving gear 1402 and the driven gear 1403 are meshed and connected, a cleaning sleeve 1404 is fixedly installed on the inner wall of the driven gear 1403, and a cleaning brush 1405 is arranged on the inner wall of the cleaning sleeve 1404.

The upper surface of the base 1 is provided with grooves corresponding to the driving gear 1402 and the driven gear 1403. A driving motor 1401 is fixedly installed on the upper end of the driving gear 1402. After the driving motor 1401 is turned on, it drives the driving gear 1402 to rotate, and the driving gear 1402 rotates to drive the driven gear 1403 to rotate. During the rotation of the driven gear 1403, the cleaning sleeve 1404 will also rotate, so that the cleaning brush 1405 can clean the dirt on the surface of the side pressure device during the up and down movement of the side pressure device.

[0026] See also Figure 1-Figure 3 A connecting plate 601 is fixedly installed inside the protective cover 6, and an electric push rod 602 is fixedly installed on the upper end of the connecting plate 601. A fixed head 603 is provided at the movable end of the electric push rod 602. The side pressure device body 7 is fixedly installed at the lower end of the fixed head 603. The electric push rod 602 can push the fixed head 603 to the lower end, thereby changing the position of the side pressure device body 7 in the protective cover 6. The upper end of the base 1 is fixedly installed with evenly distributed fixed blocks, and a lifting cylinder 11 is fixedly installed on the upper surface of the fixed block. A supporting foot 12 is provided at the movable end of the lifting cylinder 11. The lifting cylinder 11 can push the supporting foot 12 downward, thereby raising the entire base 1 to avoid the universal wheel 13 contacting the ground during the detection process and causing the base 1 to deviate.

The armrest frame 15 can be used for grasping, so as to facilitate the movement of the entire case.

[0027] When working, first hold both hands on the handrail 15, and then move the entire device to the position that needs to be surveyed in the geotechnical engineering. After determining the position, first open the jacking cylinder 11 to push the supporting foot 12 downward, thereby raising the entire base 1, and then open the hydraulic cylinder 5 to push the protective cover 6 downward to the upper end surface of the base 1, and then open the electric push rod 2 602 to push the fixed head 603 to the lower end, thereby pushing the side pressure device body 7 downward, and open the side pressure device body 7 for testing. After the test is completed, first turn on the drive motor 1401, The driving gear 1402 is driven to rotate, and the rotation of the driving gear 1402 drives the driven gear 1403 to rotate. During the rotation of the driven gear 1403, the cleaning sleeve 1404 will also rotate. Then the hydraulic cylinder 5 is opened to move the pressure gauge body 7 upward. During the movement, the cleaning brush 1405 will clean the dust on the surface of the pressure gauge body 7. When the pressure gauge moves to the inside of the protective sleeve 6, the electric push rod 801 is opened to push the nozzle 802 to move below the protective sleeve 6. Then the solenoid valve is opened, and the nozzle 802 will spray water to wash the pressure gauge body 7.

[0028] Through the above steps, the protective cover 6 is used to hide the barometer body 7 inside, which can avoid dust accumulation on the surface of the barometer body 7 and avoid damage to the barometer body 7 caused by impact from foreign objects. At the same time, after the barometer body 7 is retracted into the protective cover 6, the flushing component 8 can flush the surface of the barometer body 7 from the bottom side, and the dirt on the bottom and surface of the barometer body 7 can be flushed away, which can avoid dirt adhering to the bottom of the instrument, so as to solve the problem that most devices cannot hide and protect the instrument body, and cannot completely clean the dust and dirt on the bottom of the instrument, resulting in a certain deviation in the results during the subsequent detection process.
