Description

Technical Field

[0001] This application relates to the field of density testing, and more specifically, to a multi-channel water injection device for density testing using the water injection method. Background Technology

[0002] The water injection method is a test method for determining the density of coarse-grained soil (such as gravel and crushed stone) and coarse-grained soil (such as pebbles and boulders) in the field. Its core principle is to inject water into the test pit, use the volume of water to estimate the volume of soil, and then calculate the density of the soil.

[0003] The existing water-filling method for density testing involves digging a cylindrical test pit with a diameter of about 150 mm on the surface of the soil to be tested, then laying a plastic film on the bottom and walls of the pit to prevent water from seeping into the soil pores, filling the pit with water until it is level with the ground, recording the volume of water injected, and finally estimating the volume of the soil based on the volume of water, and calculating the dry density and compaction degree of the soil in combination with the mass of the soil sample.

[0004] However, the existing water injection devices still have the following shortcomings in use: most of the existing water injection devices are single-channel water injection devices with only one water outlet, which means that the water injection device cannot inject water into multiple test pits at the same time, and can only test multiple test pits one by one, which reduces the testing efficiency of the water injection method. Utility Model Content

[0005] To overcome the above shortcomings, this application provides a multi-channel water injection device for compaction testing by water filling method, which aims to improve the problem that the water injection device cannot inject water into multiple test pits at the same time, and can only test multiple test pits one by one, thus reducing the testing efficiency of water filling method.

[0006] This application provides a multi-channel water injection device for compaction testing by water filling method, including a water tank, a base connected to the bottom of the water tank, a main valve connected to the output end of the water tank, a first conveying pipe connected to the output end of the main valve, an output mechanism for outputting water inside the water tank on one side of the base, and a lifting mechanism on one side of the base.

[0007] The output mechanism includes multiple sets of second conveying pipes, one end of which is connected to a first conveying pipe, and the other end of which is connected to a branch valve. The output end of the branch valve is connected to an output pipe.

[0008] In one specific implementation, the output mechanism further includes a base plate connected to the outer surface of the base, a first housing connected to the top of the base plate, a first motor connected to the top of the first housing, an output shaft of the first motor passing through the first housing and connected to a first screw, and the other end of the first screw being rotatably connected inside the first housing.

[0009] In the above implementation process, by setting the first motor, the output shaft of the first motor can be controlled to rotate, thereby driving the first screw to rotate inside the first housing.

[0010] In one specific implementation, the outer surface of the first screw is threadedly connected to a first threaded seat, and the first threaded seat is slidably connected inside the first housing.

[0011] In the above implementation process, by setting the first threaded seat, the first threaded seat can be driven to move up and down inside the first housing when the first screw rotates.

[0012] In one specific implementation, a Z-shaped component is connected to one side of the first threaded seat, and a track plate is connected to one end of the Z-shaped component. Multiple sets of sliding grooves are formed through one side of the track plate.

[0013] In the above implementation process, by setting the Z-shaped part, when the first threaded seat moves, the Z-shaped part can be driven to move up and down, thereby driving the track plate to move up and down.

[0014] In one specific implementation, the top of the base plate is connected to two sets of first vertical plates, one side of the first vertical plates is connected to a second vertical plate, and a first crossbar and a second crossbar are connected between the two sets of second vertical plates. The outer surface of the first crossbar is slidably connected to multiple sets of first sliding members, and the outer surface of the second crossbar is slidably connected to multiple sets of second sliding members.

[0015] In the above implementation process, by setting the first crossbar and the second crossbar, the first slider can slide on the outer surface of the first crossbar, the first crossbar defines the sliding direction of the first slider, and the second slider slides on the outer surface of the second crossbar, the second crossbar defines the sliding direction of the second slider.

[0016] In one specific implementation, a U-shaped component is connected to one side of the first slider, and the U-shaped component is connected to one side of the second slider.

[0017] In the above implementation process, by setting the U-shaped part, the first sliding part and the second sliding part can be driven to slide when the U-shaped part moves.

[0018] In one specific implementation, the U-shaped member has a protrusion inside, which is slidably connected inside the sliding groove.

[0019] In the above implementation process, by setting the protrusion, when the track plate moves up and down, the protrusion can be driven to slide inside the sliding groove, thereby driving the U-shaped part to move, adjusting the position of multiple sets of output pipes, and simultaneously injecting water into multiple sets of test pits through multiple sets of output pipes.

[0020] In one specific implementation, the lifting mechanism includes a second housing, a second motor connected to the top of the second housing, an output shaft of the second motor passing through the second housing and connected to a second screw, and the other end of the second screw being rotatably connected inside the second housing.

[0021] In the above implementation process, by setting up the second motor, the output shaft of the second motor can be controlled to rotate, thereby driving the second screw to rotate inside the second housing.

[0022] In one specific implementation, the outer surface of the second screw is threadedly connected to a second threaded seat, which is slidably connected inside the second housing.

[0023] In the above implementation process, by setting the second threaded seat, the second threaded seat can be driven to move up and down inside the second housing when the second screw rotates.

[0024] In one specific implementation, a movable member is connected to one side of the second threaded seat, and the second feed tube passes through the top of the movable member and is connected inside the movable member.

[0025] In the above implementation process, by setting the moving part, when the second threaded seat moves, the moving part can be driven to move, and the height of the output pipe can be adjusted. This can solve the problem of different horizontal heights of multiple test pits, adjust the output pipe to an appropriate height, and the length of the second material conveying pipe is long enough to allow the moving part to move up and down and left and right.

[0026] Compared with the prior art, the beneficial effects of this application are as follows: By setting up the output mechanism and the lifting mechanism, the position of multiple sets of output pipes can be adjusted by controlling the first motor, and multiple sets of test pits can be injected with water at the same time, which speeds up the detection efficiency of the water injection method. Furthermore, by controlling the second motor, the height of the output pipes can be adjusted. When the horizontal heights of multiple sets of test pits are different, the output pipes can be adjusted to an appropriate height, thereby solving the problem that the water injection device cannot inject water into multiple test pits at the same time, and can only test multiple test pits one by one, which reduces the detection efficiency of the water injection method.

[0037] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0038] Please see Figure 1 This application provides a multi-channel water injection device for density testing by water filling method, including a water tank 1.

[0039] Please see Figure 1 and Figure 2The bottom of the water tank 1 is connected to a base 4. The output end of the water tank 1 is connected to a main valve 6. The output end of the main valve 6 is connected to a first conveying pipe 5. An output mechanism 2 for outputting water from the inside of the water tank 1 is provided on one side of the base 4. A lifting mechanism 3 is provided on one side of the base 4.

[0040] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The output mechanism 2 includes multiple sets of second conveying pipes 204. One end of the second conveying pipe 204 is connected to the first conveying pipe 5, and the other end of the second conveying pipe 204 is connected to the branch valve 2019. The output end of the branch valve 2019 is connected to the output pipe 2020.

[0041] In a specific configuration, the output mechanism 2 also includes a base plate 201, which is connected to the outer surface of the base 4. The top of the base plate 201 is connected to a first housing 203, and the top of the first housing 203 is connected to a first motor 2015. The output shaft of the first motor 2015 passes through the first housing 203 and is connected to a first screw 2016. The other end of the first screw 2016 is rotatably connected inside the first housing 203. By configuring the first motor 2015, the first screw 2016 can be rotated inside the first housing 203 by controlling the rotation of the output shaft of the first motor 2015.

[0042] In a specific configuration, the outer surface of the first screw 2016 is threadedly connected to a first threaded seat 2017, which is slidably connected inside the first housing 203. The first threaded seat 2017 can move up and down inside the first housing 203 when the first screw 2016 rotates.

[0043] In a specific configuration, a Z-shaped component 2013 is connected to one side of the first threaded seat 2017, and a track plate 205 is connected to one end of the Z-shaped component 2013. Multiple sliding grooves 2014 are formed through one side of the track plate 205. The Z-shaped component 2013 can move up and down when the first threaded seat 2017 moves, thereby moving the track plate 205 up and down.

[0044] In a specific configuration, two sets of first vertical plates 202 are connected to the top of the base plate 201, and a second vertical plate 206 is connected to one side of the first vertical plate 202. A first horizontal bar 208 and a second horizontal bar 2010 are connected between the two sets of second vertical plates 206. Multiple sets of first sliding members 209 are slidably connected to the outer surface of the first horizontal bar 208, and multiple sets of second sliding members 2011 are slidably connected to the outer surface of the second horizontal bar 2010. Through the configuration of the first horizontal bar 208 and the second horizontal bar 2010, the first sliding member 209 can slide on the outer surface of the first horizontal bar 208, and the first horizontal bar 208 defines the sliding direction of the first sliding member 209. The second sliding member 2011 slides on the outer surface of the second horizontal bar 2010, and the second horizontal bar 2010 defines the sliding direction of the second sliding member 2011.

[0045] In a specific configuration, a U-shaped component 207 is connected to one side of the first slider 209, and the U-shaped component 207 is connected to one side of the second slider 2011. The U-shaped component 207 allows the first slider 209 and the second slider 2011 to slide when the U-shaped component 207 moves.

[0046] In the specific setup, the U-shaped part 207 is internally connected to a protrusion 2012, which is slidably connected inside the sliding groove 2014. The protrusion 2012 can slide inside the sliding groove 2014 when the track plate 205 moves up and down, thereby moving the U-shaped part 207 and adjusting the position of the multiple sets of output pipes 2020. Water is then injected into multiple test pits simultaneously through the multiple sets of output pipes 2020.

[0047] In a specific configuration, the lifting mechanism 3 includes a second housing 301. A second motor 302 is connected to the top of the second housing 301. The output shaft of the second motor 302 passes through the second housing 301 and is connected to a second screw 303. The other end of the second screw 303 is rotatably connected inside the second housing 301. By configuring the second motor 302, the output shaft of the second motor 302 can be controlled to rotate, thereby driving the second screw 303 to rotate inside the second housing 301.

[0048] In a specific configuration, the outer surface of the second screw 303 is threadedly connected to a second threaded seat 304, which is slidably connected inside the second housing 301. The second threaded seat 304 can move up and down inside the second housing 301 when the second screw 303 rotates.

[0049] In a specific configuration, a movable component 2018 is connected to one side of the second threaded seat 304. The second feed pipe 204 passes through the top of the movable component 2018 and is connected inside the movable component 2018. The movable component 2018 can be moved when the second threaded seat 304 moves, thereby adjusting the height of the output pipe 2020. This can solve the problem of different horizontal heights in multiple test pits, allowing the output pipe 2020 to be positioned at an appropriate height. Furthermore, the length of the second feed pipe 204 is long enough to allow the movable component 2018 to move up and down and left and right.

[0050] The working principle of this multi-channel water injection device for compaction testing using the water injection method is as follows: When using the multi-channel water injection device for compaction testing using the water injection method, the first motor 2015 drives the first screw 2016 to rotate, which in turn drives the first threaded seat 2017 to move inside the first housing 203, which in turn drives the Z-shaped part 2013 to move, which in turn drives the track plate 205 to move up and down, which in turn drives the protrusion 2012 to slide inside the sliding groove 2014, which in turn drives the U-shaped part 207 to move, adjusting the position of the multiple sets of output pipes 2020, and so on. Simultaneously, water is injected into multiple test pits to accelerate the testing efficiency of the water injection method. Furthermore, by controlling the second motor 302 to drive the second screw 303 to rotate, the second threaded seat 304 to move inside the second housing 301, and the moving part 2018 to move, the height of the output pipe 2020 can be adjusted. When the horizontal heights of multiple test pits are different, the output pipe 2020 can be adjusted to an appropriate height, thereby solving the problem that the water injection device cannot inject water into multiple test pits at the same time, and can only test multiple test pits one by one, which reduces the testing efficiency of the water injection method.

[0051] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
