Description

Technical Field

[0001] The present invention relates to the technical field of soil monitoring equipment, and in particular to a fixed-point monitoring equipment for soil and a use method thereof. Background Art

[0002] Sandy soil particles are large, and when they are naturally deposited or acted upon by external forces (such as water flow and wind), a certain degree of stratification will occur. Coarser sand particles may be deposited in the lower layer, while relatively finer sand particles and silt may be distributed in the upper layer. This layered structure will result in different soil particle compositions at different heights. In addition, sandy soil has a large porosity, and the distribution and movement of water and nutrients in the soil will also be affected by particle stratification. For example, near the surface, soil particles may be relatively loose due to factors such as wind and sun, while at deeper locations, soil particles may be relatively compact due to compaction. Therefore, it is necessary to test sandy soil particles at different heights.

[0003] When existing soil fixed-point monitoring equipment is used to detect sandy soil, it cannot monitor soil at different heights at the same time.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] See attached Figure 1-Figure 7 A fixed-point monitoring device for soil comprises a horizontal support plate 100 and a monitoring member 1 and a hollow vertical pipe 3 mounted on the horizontal support plate 100, a forward and reverse motor 2 is fixedly mounted on the horizontal support plate 100, a threaded drive shaft 7 located in the hollow vertical pipe 3 is fixedly mounted on the output end of the forward and reverse motor 2, a layered monitoring device is arranged in the hollow vertical pipe 3, and a stabilizing device 9 mounted on the hollow vertical pipe 3 is arranged at the end of the threaded drive shaft 7;

[0038] The layer monitoring device includes a detection seat 4 threadedly mounted on a threaded drive shaft 7 and capable of movement, one side of the detection seat 4 is slidably connected to the inner wall of the hollow standpipe 3, and the layer monitoring device also includes a plurality of sand retaining positioning mechanisms 5 equidistantly arranged on the wall of the hollow standpipe 3;

[0039] The detection seat 4 includes an oil cylinder 41, a force groove 42 is opened on the first side of the oil cylinder 41, a force rod 44 is arranged in the force groove 42, a push groove 43 is opened on the second side of the oil cylinder 41 and a push rod 45 is arranged in the push groove 43, a detection rod 200 is fixed to the push rod 45 at one end away from the oil cylinder 41, and the detection seat 4 also includes a pulling mechanism capable of pushing the detection rod 200 to move;

[0040] The sand retaining positioning mechanism 5 includes an opening 51 opened on the hollow vertical pipe 3 and a sand retaining sleeve 52 arranged around the opening 51. The sand retaining sleeve 52 is slidably installed outside the hollow vertical pipe 3. The inner wall of the sand retaining sleeve 52 is provided with a protruding plate 53 and a rubber tube 54 passing through the opening 51. The sand retaining positioning mechanism 5 also includes a position sensor 600 arranged on the hollow vertical pipe 3.

[0041] A layered monitoring device is formed by the detection seat 4 and the sand retaining positioning mechanism 5, so that the forward and reverse motor 2 can drive the threaded drive shaft 7 to rotate, so that the detection seat 4 can move on the hollow vertical pipe 3, so that the detection seat 4 passes through each sand retaining positioning mechanism 5 from top to bottom, and the position sensor 600 at each sand retaining positioning mechanism 5 can detect the moving position of the detection seat 4. When it is necessary to monitor at the height where the sand retaining positioning mechanism 5 is located, the detection seat 4 will stop, and the force-bearing groove 42 will be pushed to squeeze the oil cylinder 41 through the pulling mechanism, so that the pushing groove 43 pushes the detection rod 200 out of the detection seat 4, and at this time the sand retaining sleeve 52 will move, and when the detection rod 200 comes out, the rubber guide tube 54 will move to the detection rod 200, so that the detection rod 200 passes through the rubber guide tube 54 and comes out of the hollow vertical pipe 3 for monitoring;

[0042] In this method, a plurality of sand retaining positioning mechanisms 5 at different heights are arranged, and then the detection base 4 is moved to different heights, so that the detection base 4 and the sand retaining positioning mechanism 5 cooperate with each other, and then the detection rod 200 is used for monitoring, thereby realizing the requirement that one device can monitor different heights.

[0043] Specifically, the pulling mechanism includes a mounting platform 61 mounted on the horizontal support plate 100, a ring 62 is rotatably mounted in the mounting platform 61, a telescopic rod 64 is fixed to the bottom of the ring 62, and the pulling mechanism also includes a deformable plate 66 that can move in the detection seat 4, one side of the deformable plate 66 extends out of the detection seat 4 along the lateral direction of the detection seat 4, a power plate 65 is fixedly mounted on one side of the deformable plate 66, the end of the telescopic rod 64 is fixedly connected to the power plate 65, a pull-back assembly is provided on both sides of the detection rod 200, and a return assembly is provided between the opening 51 and the hollow riser 3;

[0044] The pulling mechanism also includes an arc-shaped cavity 67 opened in the detection seat 4, the deformable plate 66 includes a shaped arc-shaped portion located in the arc-shaped cavity 67, and also includes a force-bearing portion located outside the detection seat 4, the force-bearing portion is arranged around the outside of the detection seat 4, the power plate 65 and the force-bearing portion of the deformable plate 66 are fixedly connected, the arc-shaped cavity 67 and the force-bearing groove 42 are connected, and the connection between the two is an arc shape. A plurality of balls 68 are arranged between the arc-shaped cavity 67 and the force-bearing groove 42, an arc stopper 69 is installed outside the detection seat 4, and the shaped arc of the deformable plate 66 The connection between the arc-shaped part and the force-bearing part is blocked by the arc-shaped stopper 69, the forward and reverse motor 2 is fixed at the bottom of the mounting platform 61, the monitoring component 1 is fixed at the top of the forward and reverse motor 2, a pull rod 63 is fixed on the circular ring 62, the pull rod 63 and the telescopic rod 64 are located on the same horizontal line, the hollow riser 3 is fixed under the horizontal support plate 100, the hollow riser 3 is provided with an arc-shaped movable opening 8 that passes through the horizontal support plate 100, the telescopic rod 64 passes through the arc-shaped movable opening 8, and the power plate 65 and the pushing end of the telescopic rod 64 are fixedly connected.

[0045] During the specific operation, the telescopic rod 64 will extend as the detection seat 4 continues to descend. When the detection seat 4 descends, the sensor 600 set by the sand blocking positioning mechanism 5 can monitor its position. When it is necessary to stop, the sensor 600 at this location transmits information to the monitoring component 1, so that the monitoring component 1 controls the forward and reverse motor 2 to stop, and during the descent of the detection seat 4, the telescopic rod 64 will extend. When the sand blocking positioning mechanism 5 stops at a certain place, the power plate 65 moves from bottom to bottom and just contacts the protruding plate 53 of the sand blocking positioning mechanism 5 at this location. At this time, the pulling mechanism is operated to make the detection rod 200 work;

[0046] Specifically, the staff pulls the pull rod 63 to rotate the ring 62, thereby driving the telescopic rod 64 to rotate, so that the telescopic rod 64 can pull the power plate 65 to move. When the power plate 65 is forced to move, it will push the force-bearing part of the deformable plate 66 to move along the outer wall of the detection seat 4, so that it can push the fixed arc portion to move in the arc cavity 67 to the force-bearing groove 42, so that it will push the ball 68 to squeeze and push the force-bearing rod 44 to move into the oil cylinder 41, so that the oil in the oil cylinder 41 is squeezed, so that the oil will push the push rod 45 out, so that the detection rod 200 can be pushed out of the push groove 43;

[0047] At the same time, the power plate 65 will push the protruding plate 53 to move, so that the protruding plate 53 will drive the sand retaining sleeve 52 to move, so that the rubber tube 54 will continue to move toward the detection rod 200. When the power plate 65 moves to the arc stopper 69, the movement stops. At this time, the rubber tube 54 will dock with the detection rod 200, and the detection rod 200 will come out of the rubber tube 54 to detect the soil at the height position.

[0048] It should be noted that the rubber tube 54 is made of rubber material, and the end thereof facing the detection rod 200 is flared, which can sufficiently ensure that the detection rod 200 will go out of the rubber tube 54, and any slight error will be eliminated by the rubber tube 54 after being squeezed and deformed by the detection rod 200;

[0049] In addition, a locking piece is provided at the pull rod 63 to ensure that the position of the pull rod 63 will not move, so that the detection seat 4 and the sand blocking positioning mechanism 5 will be fixed and will not move.

[0050] Furthermore, the two parts of the deformable plate 66 are integrally formed and are both made of steel material, which has high plasticity and toughness. After the deformable plate 66 is formed, it will be subjected to stress shaping treatment;

[0051] In addition, the arc stopper 69 can ensure the normal transmission of force at the intersection of the two parts. In addition, the arc-shaped setting at the connection between the force groove 42 and the arc cavity 67 can ensure that the first spring 48 is pushed toward the force groove 42 normally without getting stuck.

[0052] The pulling back assembly includes a pulling back groove 46 opened on both sides of the ejection groove 43, an ear plate 47 located in the pulling back groove 46 is provided at the end of the detection rod 200, a first spring 48 is fixed between the ear plate 47 and the pulling back groove 46, a return assembly is provided between the opening 51 and the hollow vertical pipe 3, which includes a slide groove 300 opened on the outer wall of the hollow vertical pipe 3, a slider 500 is fixed in the sand retaining sleeve 52, the slider 500 is slidably installed in the slide groove 300, and a fourth spring 400 is fixed between the slide groove 300 and the slider 500.

[0053] By setting the pull-back assembly and the return assembly, it is ensured that after the detection rod 200 completes the operation, the detection seat 4 and the sand blocking positioning mechanism 5 can return to their original positions normally, laying the foundation for the next operation;

[0054] Specifically, when monitoring the sand blocking positioning mechanism 5 at a certain location, when the detection rod 200 is extended, the ear plate 47 will move to stretch the first spring 48, and the movement of the sand blocking sleeve 52 will cause the slider 500 to move in the slide groove 300, so that the slider 500 squeezes the fourth spring 400, which will cause the fourth spring 400 to contract. When the monitoring operation of the sand blocking positioning mechanism 5 at a certain location is completed, it is necessary to monitor the next sand blocking positioning mechanism 5;

[0055] At this time, the locking piece of the pull rod 63 is opened, so that the staff can manually pull the pull rod 63 back to its original position. When the pull rod 63 is returned to its original position, the ring 62 will be driven to rotate in the opposite direction, so that the telescopic rod 64 will pull the deformable plate 66 out of the arc cavity 67. At this time, the pushing force of the first spring 48 on the force-bearing groove 42 disappears, and the lifting force of the push-out groove 43 on the detection rod 200 also disappears. At this time, the first spring 48 of the pull-back assembly will shrink, so that the detection rod 200 will enter the push-out groove 43 again, and at this time the protruding plate 53 no longer has the push and obstruction of the power plate 65, so that the squeezed fourth spring 400 will rebound, and the rebounded fourth spring 400 will push the slider 500 to move, thereby driving the sand retaining sleeve 52 to move back to its original position, thus laying a good foundation for the next operation.

[0056] See attached Figure 1 , Figure 3 , Figure 4 , Figure 8 and Fig. 9 A stabilizing device 9 is installed at the bottom of the hollow vertical pipe 3. The stabilizing device 9 includes a mounting tube 91 fixed at the bottom of the hollow vertical pipe 3. The threaded drive shaft 7 extends into the mounting tube 91. The extended portion of the threaded drive shaft 7 is threadedly mounted with a cylindrical seat 92. The thread pitch of the extended portion of the threaded drive shaft 7 is smaller than the thread pitch of the portion located in the hollow vertical pipe 3. The cylindrical seat 92 is located in the mounting tube 91. The cylindrical seat 92 is slidably connected to the inner wall of the mounting tube 91. The end of the cylindrical seat 92 is a cut-out tube 98.

[0057] It should be noted that the thread pitch of the threaded drive shaft 7 in the mounting tube 91 is smaller than the thread pitch of the threaded drive shaft 7 in the hollow riser 3, so that the detection seat 4 moves faster and the cylindrical seat 92 moves slower. Specifically, in the present embodiment, when the detection seat 4 moves to the bottom sand retaining positioning mechanism 5, the detection seat 4 moves to the end of the stroke, and at this time, the cylindrical seat 92 also moves to the end of the stroke.

[0058] The stabilizing device 9 also includes a supporting mechanism, which includes a plurality of arc plates 93 located at the bottom of the hollow riser 3, and the plurality of arc plates 93 are equidistantly distributed around the hollow riser 3. One end of the arc plate 93 is hinged to the outer wall of the bottom of the hollow riser 3, and a stabilizing tilt component 94 is fixed between the middle part of the arc plate 93 and the outer wall of the mounting tube 91. A plurality of pushing components are provided on the circumference of the cylindrical seat 92. The stabilizing tilt component 94 includes a stabilizing tilt cylinder 941 fixed on the mounting tube 91, and also includes a stabilizing tilt column 942 slidably installed in the stabilizing tilt cylinder 941. A second spring 943 is fixed between one end of the stabilizing tilt column 942 and the stabilizing tilt cylinder 941, and the other end of the stabilizing tilt column 942 is hinged to the bottom of the arc plate 93. The pushing component includes a mounting hole 96 opened on the cylindrical seat 92, and a round-headed push column 95 is slidably installed in the mounting hole 96, and a third spring 97 is fixed between the round-headed push column 95 and the mounting hole 96.

[0059] When the whole device is in operation, the land to be monitored is first detected, and a hole for the hollow riser 3 to enter is drilled in the land by a drilling rig. This is an operation step well known in the art, so it will not be described in detail.

[0060] Then the hollow standpipe 3 is inserted into the hole. Because the looseness of the sandy soil will compact the sides of the hollow standpipe 3, the hollow standpipe 3 is fixed. When the layer monitoring device is in operation, the forward and reverse motor 2 will generate vibration when it is driven. In order to prevent the vibration force from collapsing the hole in the sandy soil, the threaded drive shaft 7 rotates to drive the cylindrical seat 92 to move downward, so that the cut-out tube 98 of the cylindrical seat 92 will be inserted into the deeper soil, which will make the hollow standpipe 3 more firmly fixed.

[0061] At this time, when the cylindrical seat 92 comes out of the installation tube 91, the round-headed push column 95 is not blocked by the installation tube 91, and the extension force of the third spring 97 will directly extend the round-headed push column 95 from the installation hole 96, and the pop-up round-headed push column 95 will form a thrust on the bottom of the arc plate 93, so that the end of the arc plate 93 is pushed to become a vertical shape. At this time, the stabilizing column 942 is pulled to extend the second spring 943, and the arc plates 93 distributed at the bottom of the hollow riser 3 and in a vertical shape at this moment will form support for the bottom side wall of the hole in the sandy soil, thereby improving the stability of the hole and preventing it from collapsing, and each sand retaining sleeve 52 will also support the outer wall of the hole at that location. Combined with this, the safety of the hole is protected, providing a guarantee for the smooth progress of the monitoring operation.

[0062] The present invention also discloses a method for using a fixed-point monitoring device for soil, comprising the following steps:

[0063] S1: Preparation stage, the land to be monitored is detected, and a hole for the hollow riser 3 to enter is drilled in the land to be monitored;

[0064] S2: During the installation phase, the hollow riser 3 is inserted into the hole. When the hollow riser 3 touches the bottom, the installation is completed.

[0065] S3: During the use phase of the layered monitoring device, the forward and reverse motors 2 are started to drive the threaded drive shaft 7 to rotate, so that the detection seat 4 moves downward. When passing through a certain sand retaining positioning mechanism 5 during the movement, the forward and reverse motors 2 are turned off as needed to stop the detection seat 4 from moving downward. The location of the sand retaining positioning mechanism 5 at this location is the monitoring operation area. Subsequently, the detection rod 200 is moved through the rubber conduit 54 and out of the hollow vertical pipe 3 through the pulling mechanism. The detection rod 200 contacts the soil at the monitoring operation area to perform monitoring operations, and the monitoring data is transmitted to the monitoring component 1 in real time.

[0066] S4: The stabilizing device is in use. When the forward and reverse motors 2 drive the threaded drive shaft 7 to rotate so that the detection base 4 moves downward, the threaded drive shaft 7 drives the stabilizing device 9 to operate.

[0067] It should be noted that, in this embodiment, in step S2, when the device is manually picked up to insert the hollow riser 3 into the hole, after the hollow riser 3 touches the bottom, the horizontal support plate 100 is located on the ground outside the hole, and then the fixing nails provided on the horizontal support plate 100 are driven into the ground to stabilize the device;

[0068] In addition, it should be noted that in step S4, specifically, when the forward and reverse motors 2 drive the threaded drive shaft 7 to rotate so that the detection seat 4 moves downward, the cylindrical seat 92 will also move downward and be inserted into the soil at the bottom of the hole through the cut tube 98. When the cylindrical seat 92 moves downward, the round-headed push pin 95 will pop out to apply pressure to the end of the arc plate 93 to make it vertical. Several vertical arc plates 93 will form support for the bottom side wall of the hole in the sandy soil.

[0069] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
