Description

Technical Field

[0001] The utility model relates to the technical field of sensor embedding, in particular to a sensor embedding device. Background Art

[0002] Preferred soil flow is a common phenomenon in geotechnical engineering monitoring, especially in geotechnical field tests. It is controlled by many factors, such as large voids in the soil, soil texture, initial soil moisture content, sensor cable burial, etc. Preferred flow refers to the phenomenon that water and solutes in a medium with large pores bypass the matrix and move rapidly through a dominant path. Although preferred soil flow is beneficial to soil irrigation or soil permeability under certain conditions, it will have a great impact on the test results in most geotechnical seepage tests. For example, when burying sensors on site for data monitoring, since the sensor cables are usually led from underground to the ground, if the sensor burial hole is not backfilled tightly around the sensor cable, rainwater can easily seep downward along the sensor cable to form a preferred flow, thereby affecting the sensor's measurement results.

[0003] At present, the method of burying sensors in field tests is: drilling holes on site, burying sensors at a specified soil depth, leading the sensor cables from the sensor burial location to the ground, and then backfilling the gap between the cables and the surrounding soil with backfill soil. In order to reduce the dominant flow of rainwater when burying sensors on site, cement slurry is usually used to fill and compact the gap between the cable and the soil from a certain depth to the ground, or bentonite slurry is used to pour the gap between the sensor cable and the soil, thereby reducing the dominant flow of external rainwater downward along the sensor cable during rainfall.

[0004] However, the existing solutions for reducing the dominant flow of field sensor burial have four shortcomings:

[0005] First, the existing scheme is prone to cement or bentonite cracking under repeated on-site weather conditions. Once cracked, the effect of reducing the dominant flow will be greatly weakened or even ineffective.

[0006] Second, the existing solution of using cement slurry or bentonite slurry to fill the cracks can only be operated in the shallow range below the ground, and it is difficult to operate in the deep soil layer;

[0007] Third, the existing solutions cannot actively control the construction process, and cannot detect the sealing effect after completion;

[0008] Fourth, the existing solutions cannot easily recover the sensors after the monitoring test is completed. Utility Model Content

[0009] The technical problem to be solved by the embodiment of the utility model is that the dominant flow affects the accuracy of sensor measurement and the steps for recovering the sensor are complicated.

[0010] In order to solve the above problems, the embodiment of the utility model discloses a sensor embedding device, which can achieve the technical effect of conveniently installing / recovering the sensor and improving the accuracy of sensor measurement.

[0011] The utility model provides a sensor embedding device, which includes a porous tube with multiple air holes; an elastic mechanism surrounding the porous tube; a shell including a top cap and a bottom cap, the top cap is respectively connected to the porous tube and the elastic mechanism, the bottom cap is respectively connected to the porous tube and the elastic mechanism, a sensor is provided at the bottom of the bottom cap, and the cable of the sensor passes through the porous tube, the top cap and the bottom cap respectively; and a sleeve surrounds the top cap, the elastic mechanism and the bottom cap respectively.

[0012] A further technical solution is that it also includes a sealing valve, the top cap is provided with an opening, the cable passes through the opening, and the sealing valve is arranged on the opening.

[0013] A further technical solution is that it also includes an air pressure detection device and an air valve, wherein the air valve is arranged on the sealing valve and connected to the detection device.

[0014] A further technical solution is that it also includes a wireless communication device, and the wireless communication device is connected to the air pressure detection device.

[0015] A further technical solution is that the porous tube includes an upper part, a middle part and a lower part, the middle part is respectively connected to the upper part and the lower part, a plurality of air holes are evenly arranged on the middle part, the upper part is embedded in the top cap, and the lower part is embedded in the bottom cap.

[0016] A further technical solution is that it also includes a first sealing ring and a second sealing ring, wherein the first sealing ring is connected to the elastic mechanism and the top cap respectively, and the second sealing ring is connected to the elastic mechanism and the bottom cap respectively.

[0017] A further technical solution is that it also includes a cable sleeve, which is arranged on the cable and connected to the sensor.

[0018] A further technical solution is that it also includes a third sealing ring, and the third sealing ring is respectively connected to the elastic mechanism, the cable sleeve and the sensor.

[0019] A further technical solution is that the diameter of the air holes ranges from 2 to 5 mm.

[0020] A further technical solution is that the elastic mechanism is an airbag, and the thickness of the airbag ranges from 0.5 to 2 mm.

[0021] Compared with the prior art, the technical effects that can be achieved by the embodiments of the present invention include:

[0022] The air pressure in the elastic mechanism is used to compress the bentonite mud in the surrounding gaps, so that the bentonite mud can fully enter the large gaps in the surrounding soil, reducing the dominant flow of rainwater along the depth direction of the hole caused by drilling when burying the sensor. Since the bentonite mud around the elastic mechanism is always under the action of the air pressure of the elastic mechanism, the possibility of cracking of the bentonite mud is very small even in dry weather conditions. After the field test is completed, the sensor can be easily removed from the ground and recycled, which greatly saves the cost of field test monitoring. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] See also Figure 1-4 , the embodiment of the utility model provides a sensor embedding device. The sensor embedding device includes a porous tube 1, which is provided with a plurality of air holes 11; an elastic mechanism 2, which surrounds the porous tube 1; a shell 3, which includes a top cap 31 and a bottom cap 32, the top cap 31 is respectively connected to the porous tube 1 and the elastic mechanism 2, the bottom cap 32 is respectively connected to the porous tube 1 and the elastic mechanism 2, a sensor 91 is provided at the bottom of the bottom cap 32, and the cable of the sensor 91 passes through the porous tube 1, the top cap 31 and the bottom cap 32 respectively; a sleeve 4, which surrounds the top cap 31, the elastic mechanism and the bottom cap 32 respectively. The specific introduction of each component is as follows:

[0034] In this embodiment, the porous tube 1 can be made of plastic or metal material, one end of the porous tube 1 is embedded in the top cap 31, and the other end of the porous tube 1 is embedded in the bottom cap 32. The porous tube 1 is used to support the elastic mechanism 2 and apply air pressure to the elastic mechanism 2 through the air hole 11. The elastic mechanism 2 is made of elastic material such as silicone, latex, etc., including an air bag and an elastic film, which surrounds the porous tube 1. In this embodiment, the thickness of the elastic mechanism 2 is 1 mm, one end of the elastic mechanism 2 and one end of the porous tube 1 are embedded in the top cap 31, and the other end of the elastic mechanism 2 and the other end of the porous tube 1 are embedded in the bottom cap 32, so that a cavity is formed between the elastic mechanism 2 and the porous tube 1, and the cavity is connected with the inside of the porous tube 1 through the air vent 11. The elastic mechanism 2 can withstand high air pressure. When subjected to air pressure, the elastic mechanism 2 will bulge toward the surrounding area, thereby expanding the volume of the above-mentioned cavity. Usually, the maximum diameter of the elastic mechanism 2 after swelling is 2 times or more of the diameter of the casing 4. The casing 4 is cylindrical and is sleeved on the top cap 31, the elastic mechanism and the bottom cap 32. It is made of hard material and is used to prevent the hole from collapsing when the sensor 91 is buried and block the surrounding soil pressure. The bottom cap 32 is provided with a circular groove, and the sensor 91 is installed in the circular groove, and the sensor 91 can move up and down in the circular groove of the bottom cap 32. Usually, before the burying operation, the lower end of the sensor 91 is adjusted to extend 5 to 10 mm, for example 8 mm, beyond the lower end of the bottom cap 32, so as to achieve close contact between the sensor 91 and the surrounding soil, thereby improving the accuracy of the measurement.

[0035] The use process of the sensor embedding device is as follows:

[0036] Fix the sensor 91 on the bottom cap 32; put the elastic mechanism 2 on the outside of the porous tube 1, and install and fix the lower end of the elastic mechanism 2 and the lower end of the porous tube 1 in the bottom cap 32; install and fix the upper end of the elastic mechanism 2 and the upper end of the porous tube 1 in the top cap 31; place the bottom cap 32 installed with the sensor 91, the elastic mechanism 2 and the porous tube 1 in the sleeve 4, and complete the installation steps of the sensor embedding device.

[0037] A hole is drilled in the soil on site to the specified depth where the sensor 91 is to be buried. The diameter of the hole should be larger than the outer diameter of the casing 4. Then, a sensor embedding device is placed in the hole until it reaches the bottom of the hole, until the sensor 91 is in close contact with the soil at the bottom of the hole, and the top cap 31 is exposed from the soil surface, or the bottom surface of the top cap 31 is buried 5 to 10 mm below the soil surface; the space between the elastic mechanism 2 and the casing 4 is filled with bentonite slurry; the casing 4 is rotated and pulled out; air or nitrogen is injected into the elastic mechanism 2 to cause the elastic mechanism 2 to swell and compress the bentonite slurry on all sides, so that the bentonite slurry fills the large holes in the surrounding soil, and then the gap between the elastic mechanism 2 and the surrounding soil is completely filled and dense; after a period of stabilization, when the air pressure inside the elastic mechanism 2 squeezes the surrounding bentonite slurry out of the ground, the embedding step of the sensor 91 is completed.

[0038] After the monitoring of the sensor 91 is completed, the sensor 91 can be taken out from the porous tube 1 by rotating the cable, and the porous tube 1 and the elastic mechanism 2 are taken out, and finally the hole is backfilled to complete the recovery step of the sensor 91 and its related equipment.

[0039] The technical effects that can be achieved by the embodiments of the present utility model include:

[0040] The air pressure in the elastic mechanism 2 is used to compress the bentonite slurry in the surrounding gaps, so that the bentonite slurry fully enters the large gaps in the surrounding soil, reducing the dominant flow of rainwater along the depth direction of the hole caused by drilling when the sensor 91 is buried. Since the bentonite slurry around the elastic mechanism 2 is always under the action of the air pressure of the elastic mechanism 2, the possibility of the bentonite slurry cracking is very small even in dry weather conditions. After the field test is completed, the sensor 91 can be easily taken out from the ground and recycled, which greatly saves the field test monitoring cost.

[0041] Continue to see Figure 1-4 In this embodiment, a sealing valve 5 is also included. The top cap 31 is provided with an opening, the cable passes through the opening, and the sealing valve 5 is arranged on the opening.

[0042] Furthermore, it also includes an air pressure detection device 61 and an air valve 62. The air valve 62 is arranged on the sealing valve 5 and connected to the detection device.

[0043] Specifically, an opening is provided in the top cap 31, and the diameter of the opening is larger than the outer diameter of the cable sleeve 8. The cable sleeve 8 can extend through the opening to the outside atmosphere. A sealing valve 5 is installed at the outlet of the opening. The sealing valve 5 is provided with two holes, one hole is used to pass the cable and seal, and the other hole is used to install the pore valve. There is a mounting hole for the air pressure detection device 61 at the connection between the top cap 31 and the pore valve. The mounting hole is fixed by threading the air pressure detection device 61. The air pressure detection device 61 includes a barometer for real-time monitoring of changes in air pressure in the airbag. One end of the pore valve is connected to the opening, and the other end is connected to an external air source (such as an air compressor or a gas cylinder). The function of the pore valve is to inflate or deflate the elastic mechanism 2. The sealing valve 5 and the top cap 31 are fixedly connected by threads, and the pore valve and the sealing valve 5 are fixed by threads.

[0044] The air pressure in the elastic mechanism 2 can be actively controlled through the air hole valve to achieve active control of reducing the dominant flow, and the air pressure value can be intuitively displayed through the air pressure detection device 61, which is easy to operate.

[0045] In this embodiment, the use process of the sensor embedding device is as follows:

[0046] Fix the sensor 91 on the bottom cap 32; put the elastic mechanism 2 on the outside of the porous tube 1, and install and fix the lower end of the elastic mechanism 2 and the lower end of the porous tube 1 in the bottom cap 32; install and fix the upper end of the elastic mechanism 2 and the upper end of the porous tube 1 in the top cap 31; place the bottom cap 32 installed with the sensor 91, the elastic mechanism 2 and the porous tube 1 in the sleeve 4, and complete the installation steps of the sensor embedding device.

[0047] A hole is drilled in the soil on site to the specified depth where the sensor 91 is to be buried. The diameter of the hole should be larger than the outer diameter of the casing 4. Then, a sensor embedding device is placed in the hole until it reaches the bottom of the hole, until the sensor 91 is in close contact with the soil at the bottom of the hole, and the top cap 31 is exposed from the soil surface, or the bottom surface of the top cap 31 is buried 5 to 10 mm below the soil surface; the space between the elastic mechanism 2 and the casing 4 is filled with bentonite slurry; the casing 4 is rotated and pulled out; air or nitrogen is injected into the elastic mechanism 2 to cause the elastic mechanism 2 to swell and compress the bentonite slurry on all sides, so that the bentonite slurry fills the large holes in the surrounding soil, and then the gap between the elastic mechanism 2 and the surrounding soil is completely filled and dense; after a period of stabilization, when the air pressure inside the elastic mechanism 2 squeezes the surrounding bentonite slurry out of the ground, the embedding step of the sensor 91 is completed.

[0048] When the air pressure in the elastic mechanism 2 measured by the barometer reaches stability, the increase in air pressure can be stopped and the air hole valve on the top cap 31 can be closed at this time; in one embodiment, during the test, the air pressure detection device 61 in the top cap 31 can be connected via remote communication to monitor the air pressure in the elastic mechanism 2 in real time. If the measurement data of the barometer of the top cap 31 is repeatedly unstable, it can be determined that a dominant flow is formed near the elastic mechanism 2. At this time, it can be corrected by increasing the air pressure of the elastic mechanism 2; completing the step of regulating the air pressure in the elastic mechanism 2 to reduce the influence of the dominant flow.

[0049] After the monitoring of the sensor 91 is completed, the sensor 91 can be taken out from the porous tube 1 by rotating the cable, and the porous tube 1 and the elastic mechanism 2 are taken out, and finally the hole is backfilled to complete the recovery step of the sensor 91 and its related equipment.

[0050] Furthermore, it also includes a wireless communication device, which is connected to the air pressure detection device 61.

[0051] Specifically, the air pressure detection device 61 is connected to a wireless communication device to realize remote communication. The wireless communication device includes a Wi-Fi module, a 5G module, and a Bluetooth module. It has the function of collecting data measured by the air pressure detection device 61 and sending the data to a wireless terminal, so as to realize real-time monitoring and regulation of the air pressure. For example: if the measurement data of the air pressure detection device 61 is monitored to be repeatedly unstable, it can be determined that a dominant flow is formed near the elastic mechanism 2, and it can be corrected by increasing the air pressure of the elastic mechanism 2.
