Description

Technical Field

[0001] This invention belongs to the field of geological testing technology, specifically an array displacement meter that is easy to use in the field. Background Technology

[0002] Displacement monitoring is a common method in geotechnical engineering monitoring and various slope monitoring applications, used to determine the magnitude of deep sliding surfaces and deep displacements. Array displacement gauges are frequently used; these are engineering surveying instruments applied to boreholes, tunnels, and similar locations to measure the displacement of tilting or converging settlements, as well as the horizontal displacement within soil layers or retaining structures along the vertical direction. They typically consist of one or more sensors arranged in a specific sequence, forming a functional unit. Through sensor integration, data acquisition and extraction within a given area can be achieved, facilitating subsequent big data analysis.

[0003] Existing array-type displacement detectors use multiple displacement gauges connected in series and then connected to a processor, such as... Figure 1 As shown, it can be bent arbitrarily according to actual needs to adapt to the monitoring requirements of special scenarios, making it a flexible inclinometer. Each displacement gauge is installed in a support tube, and the support tubes are flexibly connected by threads or flexible hoses, and can be wound on a winding frame, such as... Figure 2 As shown, the support tube is wound and retracted by manually rotating the winding frame, which supports the tube. However, this method has many problems, such as wasting manpower, being inconvenient to transport, being difficult to clean, and requiring an additional power supply mechanism, which greatly increases the inconvenience of on-site use. Summary of the Invention

[0004] In view of the above-mentioned shortcomings in the existing technology, the present invention provides an array displacement meter that is easy to use in the field. By redesigning its structure, especially the winding frame structure, it has better field adaptability and facilitates the workers' early transportation, later installation and use.

[0005] This invention is achieved through the following technical solution:

[0006] An array-type displacement gauge for easy field use includes a data collection box and multiple series-connected single-section displacement gauges. The data collection box is connected to the first single-section displacement gauge in sequence via cables and cable connectors. The first single-section displacement gauge is connected to the next single-section displacement gauge in sequence via a rotating mechanism and a flexible connector. A trigger locking mechanism is provided on the side of each single-section displacement gauge. The connection mode of each subsequent single-section displacement gauge is the same, and the number of single-section displacement gauges is at least two. Each single-section displacement gauge also has a winding frame. When not in use, the single-section displacement gauge is wound and fixed on the winding frame. When the single-section displacement gauge is in use, the winding frame serves as a fixing device for the remaining single-section displacement gauges. The winding frame contains a platform for fixing the data collection box and a power supply for powering the data collection box.

[0007] Furthermore, the winding frame body is a tetrahedral hollow structure. The main body of the winding frame body is a winding frame shell plate, and a storage battery is installed inside the winding frame shell plate. A spiral displacement gauge fixing groove is provided on the outer surface of the winding frame shell plate. The length and depth of the displacement gauge fixing groove on each side are adapted to a single displacement gauge. Two side plates larger than the winding frame body are provided at both ends of the winding frame body. One of the side plates has a rotating mechanism on the side away from the winding frame body and is connected to a flat plate through the rotating mechanism. The flat plate serves as a fixed platform plate, which allows the side plate to rotate circumferentially on the fixed platform plate.

[0008] Furthermore, hinges are provided on three of the four sides of the fixed platform plate, and three plates are connected by the hinges. These three plates serve as support plates. When the support plates rotate upward and fit against the two side plates, a connecting mechanism is provided between the three support plates. After locking the connecting mechanism, the support plates are closed. At this time, a surrounding plate is installed between the two unconnected support plates. This surrounding plate serves as a multi-functional table. The side of the multi-functional table has a groove, and a longitudinal protrusion is provided between the two opposing support plates. After the multi-functional table is installed, it cooperates with the three support plates to surround the outer periphery of the winding frame, fixing and protecting the single displacement gauge wound on the winding frame from the outside to avoid damaging the rotation mechanism on the single displacement gauge or triggering the locking mechanism.

[0009] There are also horizontal protrusions on the two opposing support plates. When the three support plates are flipped down and contacted and fixed again, the multi-functional table is fixed to the horizontal protrusions. At this time, the three support plates are erected, so that the entire winding frame keeps the two side plates in the positions of the upper and lower sides respectively. At this time, the multi-functional table serves as a tabletop for placing the data collection box.

[0010] Furthermore, the multi-functional tabletop is equipped with a work area, which is a hollow structure with a flip-up cover. Multiple wires and data cables are placed inside, which can provide power and data transmission for the data collection box connection. On the other side of the multi-functional tabletop, there is a circuit that can be connected to a battery.

[0011] Furthermore, the fixed platform plate is equipped with four movable wheels located at the four corners. The wheel rods of the two movable wheels closest to the multi-functional table are connected to the storage battery. When the multi-functional table is used as a desktop and inserted into place, the circuit of the multi-functional table makes contact with the two wheel rods, thereby connecting the power supply and allowing the work area to provide power to the data collection box.

[0012] Furthermore, a wiping rod is provided on the multi-functional table. The wiping rod can rotate on the multi-functional table. A U-shaped groove is provided at the end of the wiping rod. A wiping section is provided in the U-shaped groove. When the single displacement gauge passes through the U-shaped groove, the outer peripheral surface of the single displacement gauge will be wiped.

[0013] The multi-functional table is equipped with a power cord for connecting the air gun and a place to hang the air gun.

[0014] Furthermore, a solar panel connected to the fixed platform plate on one side by a hinge is provided on the side plate. The solar panel is connected to the battery through an electrical circuit. An air bladder is provided between the solar panel and the side plate as a lifting air bladder. The outside of the lifting air bladder is provided with a lifting air inlet. By inserting an air gun to inject different amounts of air, the tilt angle of the solar panel can be adjusted. Combined with the adjustment of the rotation mechanism, the solar panel can be oriented at different angles.

[0015] Furthermore, a water bag is fixed to the underside of the fixed platform plate between the moving wheels. The water bag has a water injection hole and a water drainage hole. After water is injected into the water bag, it can support the support plate from the inside out and achieve counterweight.

[0016] Furthermore, the side plate near the fixed platform plate serves as a crash barrier. The crash barrier includes a rotating base plate and a ring of crash barrier air cushions on the outer side of the rotating base plate. When inflated, the crash barrier air cushions can unfold into a ring of air cushions, preventing the single displacement gauges on the winding frame shell plate above from directly hitting the rotating base plate during lowering and retrieval, thus avoiding damage.

[0017] Furthermore, the rotating mechanism on the single-section displacement gauge includes a fixed ring, a bearing, and a rotating spindle; the fixed ring is welded to the inner wall of the single-section displacement gauge, and the rotating spindle, fixed ring, and bearing are coaxially assembled. The rotating spindle is assembled inside the fixed ring, and the two are connected together by the bearing to achieve free rotation.

[0018] The sensor module consists of a sensor mounting connector, small screws, large screws, and a sensor. The sensor integrates a triaxial accelerometer and a magnetometer. It is fixed to the sensor mounting connector by the large screw. One end of the sensor mounting connector has a through hole, and the end face of the flexible connector has a threaded hole. The small screw passes through the through hole to fix the entire sensor module to one end of the flexible connector.

[0019] The flexible joint consists of a rigid joint and a hydraulic tube containing four layers of steel wire. Rigid fasteners are fixed on the rigid joints at both ends of the flexible joint. The rigid fasteners are connected together by locking screws. When the hydraulic tube deforms, the flexible joint can bend on the same plane. The flexible joint is connected to the rotating structure at the end of the array displacement gauge steel tube by threads. One end face of the flexible joint has two threaded holes, which are fixed to the sensor module by small screws.

[0020] The trigger locking mechanism includes a main shaft, spring plate, push rod, dynamic compression spring, and trigger shaft. When the array displacement gauge enters the designated position in the pipeline, the trigger locking mechanism fixed on it is triggered under a certain force. The top of the trigger shaft is pushed, which drives the compression spring to move together. Under the action of the compression spring, the push rod will also move. At this time, the spring plate fixed on the main shaft and the push rod will deform and expand outward to lock the steel pipe on the inner wall of the pipeline. When the position of the array displacement gauge is fixed, the push rod on the main shaft also reaches the limit position.

[0021] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0022] (1) The solution provided by the present invention can be conveniently opened and installed on site, and the single displacement meter can be conveniently unfolded and retrieved, and the single displacement meter can also be conveniently fixed in the working area; especially in use, keeping the entire winding frame rotating horizontally can ensure that the single displacement meter on it can be more conveniently removed and retrieved, so as to avoid the unstable rotation speed or difficulty of rotation caused by its own gravity when rotating vertically as commonly used in the prior art.

[0023] (2) The support plate and multi-functional tabletop are set up to protect the single displacement meter during transportation. The support plate and multi-functional tabletop can also serve as a support and tabletop. Compared with the existing technology, the data collection box can be installed and fixed more conveniently while reducing space occupation.

[0024] (3) By designing the structure of the winding frame, it can generate and store electricity, and provide power and data transmission services for equipment such as laptops, which is convenient for on-site use; and the power generation is carried out by solar panels. Compared with the solar panels of the prior art, the solution of the present invention can be integrated into one body, directly using its own rotation function to adapt to the angle of sunlight, and can adjust the tilt angle by inflation to achieve efficient use of sunlight. In the process, there is no need to move the array displacement meter as a whole, but only to rotate the winding frame, which greatly reduces the trouble caused by moving and ensures stable data transmission during the operation.

[0025] (4) By setting up a wiping rod on the multi-functional table, the single displacement gauge can be cleaned and guided, improving the convenience of lowering and recycling, and ensuring that the single displacement gauge is cleaner after use and recycling. Attached Figure Description

[0050] The present invention will be further described below with reference to embodiments. It should be noted that, in this document, terms such as "upper" and "lower" are used merely for the convenience of describing the drawings and are not intended to limit the direction in actual use, nor do they necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0051] like Figure 1-13 As shown, an array-type displacement gauge for easy field use includes a data collection box 01 and multiple series-connected single-section displacement gauges 03. The data collection box 01 is connected sequentially to the first single-section displacement gauge 03 via a cable 07 and a cable connector 02. The first single-section displacement gauge 03 is connected sequentially to the next single-section displacement gauge 03 via a rotating mechanism 04 and a flexible connector 05. A trigger locking mechanism 06 is provided on the side of each single-section displacement gauge 03. The connection mode of each subsequent single-section displacement gauge 03 is the same, and the number of single-section displacement gauges 03 is at least two. Each single-section displacement gauge 03 also has a winding frame 1. When not in use, the single-section displacement gauge 03 is wound and fixed on the winding frame 1. When the single-section displacement gauge 03 is in use, the winding frame 1 serves as a fixing device for the remaining single-section displacement gauges 03. A platform for fixing the data collection box 01 is provided inside the winding frame 1, and a power supply for powering the data collection box 01 is also provided. The winding frame 1 is a tetrahedral hollow structure. The main body of the winding frame 1 is the winding frame shell plate 101. A storage battery 102 is installed inside the winding frame shell plate 101. A spiral displacement gauge fixing groove 1011 is provided on the outer surface of the winding frame shell plate 101. The length and depth of the displacement gauge fixing groove 1011 on each side are adapted to the single displacement gauge 03. The single displacement gauge can be placed in the displacement gauge fixing groove 1011. When the single displacement gauge 03 is not in use, a layer of cloth or film can be wrapped around the outermost side after the single displacement gauge 03 is placed to ensure that the single displacement gauge 03 will not fall out of the displacement gauge fixing groove 1011. Two side plates 2 with a size larger than the winding frame 1 are provided at both ends of the winding frame 1. One of the side plates 2 has a rotating mechanism on the side away from the winding frame 1 and is connected to a flat plate through the rotating mechanism. The flat plate serves as a fixed platform plate 7, which allows the side plate 2 to rotate circumferentially on the fixed platform plate 7. The rotating mechanism preferably uses a disc bearing 203, and a connecting rod can be set at the center of the disc bearing to ensure that the side plate 2 and the fixed platform plate 7 do not detach. Unlike the horizontal rotation method of the winding frame 08 and bracket 09 used in the prior art, circumferential rotation is adopted, which saves space and facilitates installation and storage. Its installation process is as follows: Figure 10 As shown, it's convenient and quick.

[0052] Hinges are provided on three of the four sides of the fixed platform plate 7, and three plates are connected by the hinges. These three plates serve as support plates 3. When the support plates 3 are rotated upward and attached to the two side plates 2, as... Figure 8As shown, a connecting mechanism (not shown in the figure) is provided between the three support plates 3. The connecting mechanism can be fixed by means of pins, bolts, etc., so as to connect and disassemble. Alternatively, a whole plate can be used and the plate can be connected to the end of the support plate 3. After locking the connecting mechanism, the support plates 3 are closed. At this time, a surrounding plate is installed between the two unconnected support plates 3. This surrounding plate serves as a multi-functional table 4. The side of the multi-functional table 4 is provided with grooves, and longitudinal protrusions are provided between the two opposing support plates 3. After the multi-functional table 4 is installed, it cooperates with the three support plates 3 to surround the outer periphery of the winding frame 1, and fixes and protects the single displacement gauge 03 wound on the winding frame 1 from the outside to avoid damaging the rotating mechanism 04 on the single displacement gauge 03 or triggering the locking mechanism 06. Preferably, the length of the support plate 3 is greater than that of the winding frame 1 to ensure that the support plate can exceed the top height of the upper side plate of the winding frame 1.

[0053] like Figure 14 As shown, there are also horizontal protrusions on the two opposing support plates 3. When the three support plates 3 are flipped down and contacted and fixed again, the multi-functional table 4 is fixed to the horizontal protrusions. At this time, the three support plates 3 are erected, so that the entire winding frame 1 keeps the two side plates 2 in the positions of the upper and lower sides respectively. At this time, the multi-functional table 4 serves as a desktop for placing the data collection box 01.

[0054] like Figure 11 As shown, the multi-functional tabletop 4 is provided with a work area 401. The work area 401 is a hollow structure with a flip-up cover. Multiple wires and data cables are placed inside, which can provide power and data transmission for the data collection box 01. On the other side of the multi-functional tabletop 4, there is a circuit that can be connected to the storage battery 102.

[0055] like Figure 9As shown, four casters 6 are located below the fixed platform plate 7, at the four corners, allowing for easy transport to a suitable position before opening the support plate 3. The two casters 6 closest to the multi-functional tabletop 4 have their wheel rods connected to the battery 102. When the multi-functional tabletop 4 is inserted into place as a desktop, the height of the horizontal protrusion 302 ensures that the circuitry of the tabletop 4 contacts these two wheel rods, connecting the power supply and allowing the work area 401 to provide power to the data collection box 01. Therefore, the casters 6 not only serve a basic transportation function but also function as a conductive mechanism, eliminating the need for an additional conductive mechanism. The casters 6 also act as a limit switch to ensure proper installation. To prevent power loss during connection, a connection lock can be installed on the multi-functional tabletop 4 to keep it locked after connection, preventing it from disengaging from the wheel rods. This facilitates power supply to the data collection box 01, which has a housing clip 10 for installing chips and other electrical components, requiring a stable current supply.

[0056] A wiping rod 402 is provided on the multi-functional tabletop 4. The wiping rod 402 can rotate on the multi-functional tabletop 4. A U-shaped groove is provided at the end of the wiping rod 402. A wiping section is provided in the U-shaped groove. The wiping section can be a loop with an open top, allowing the single-section displacement gauge to be inserted and kept in 360-degree contact with the loop. When the single-section displacement gauge 03 passes through the U-shaped groove, the outer peripheral surface of the single-section displacement gauge 03 will be wiped. The loop is a replaceable structure and can be removed for cleaning when it gets dirty. The multi-functional tabletop 4 also has a power cord for connecting an air gun and a place 403 for hanging the air gun. The air gun can assist in impact cleaning the loop.

[0057] like Figure 13 As shown, a solar panel 201 is provided on one side of the side plate 2 away from the fixed platform plate 7, and the solar panel 201 is connected to the battery 102 through a circuit. An airbag is provided between the solar panel 201 and the side plate 2 as a lifting airbag 2011. The outer side of the lifting airbag 2011 is provided with a lifting air inlet 2012. By inserting an air gun and injecting different amounts of air, the tilt angle of the solar panel 201 can be adjusted. Combined with the adjustment of the rotation mechanism, the solar panel 201 can be oriented at different angles in order to obtain the best solar energy.

[0058] like Figure 9 and 13 As shown, a water bag 5 is fixed to the lower side of the fixed platform plate 7 between the moving wheels 6. The water bag 5 is provided with a water injection hole 501 and a drain hole 502. After water is injected into the water bag 5, it can support the support plate 3 from the inside out and achieve counterweight. When not needed, the water can be drained through the drain hole 502, so that it can be stored and folded in the area above the moving wheels 6 to avoid affecting the use of the moving wheels 6.

[0059] like Figure 13 As shown, the side plate 2 near the fixed platform plate 7 serves as a crash barrier 202. The crash barrier 202 includes a rotating base plate 2021 and a ring of crash barrier air cushions 2022 disposed on the outer side of the rotating base plate 2021. After the crash barrier air cushions 2022 are inflated, a ring of air cushions can be deployed to prevent the single displacement gauge 03 on the winding frame shell plate 101 above from directly hitting the rotating base plate 2021 during lowering and retrieval, so as to avoid damage.

[0060] like Figure 4-7 As shown, the rotating mechanism 04 on the single-section displacement gauge 03 includes a fixed ring 11, a bearing 12, and a rotating spindle 13. The fixed ring 11 is welded to the inner wall of the single-section displacement gauge 03. The rotating spindle 13, the fixed ring 11, and the bearing 12 are coaxially assembled. The rotating spindle 13 is assembled inside the fixed ring 11. The two are connected together by the bearing 12 to achieve free rotation.

[0061] The sensor module consists of a sensor mounting connector 14, a small screw 15, a large screw 16, and a sensor 17. The sensor 17 integrates a triaxial accelerometer and a magnetometer and is fixed to the sensor mounting connector 14 by the large screw 16. One end of the sensor mounting connector 14 is provided with a through hole, and the end face of the flexible connector is provided with a threaded hole. The small screw 15 passes through the through hole to fix the entire sensor module to one end of the flexible connector 05.

[0062] The flexible joint 05 consists of a rigid joint 18 and a hydraulic tube 19 containing four layers of steel wire. Rigid fasteners 20 are fixed on the rigid joints 18 at both ends of the flexible joint 05. The rigid fasteners 20 are connected together by locking screws 21. When the hydraulic tube 19 deforms, the flexible joint 05 can bend on the same plane. The flexible joint 05 is connected to the rotating structure 04 at the end of the array displacement gauge steel tube 03 by threads. One end face of the flexible joint 05 is provided with two threaded holes, which are fixed together with the sensor module by small screws 15.

[0063] The trigger locking mechanism 06 includes a main shaft 22, a spring plate 23, a push rod 24, a dynamic compression spring 25, and a trigger shaft 26. When the array displacement gauge enters the designated position in the pipeline, the trigger locking mechanism 06 fixed on it is triggered under a certain force. The top of the trigger shaft 26 is pushed, which drives the compression spring 25 to move together. Under the action of the compression spring 25, the push rod 24 will also move. At this time, the spring plate 23 fixed on the main shaft 22 and the push rod 24 will deform and expand outward to lock the steel pipe 03 on the inner wall of the pipeline. When the position of the array displacement gauge is fixed, the push rod 24 on the main shaft 22 also reaches the limit position.

[0064] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still be considered improvements to the technical solution of the present invention.
