Description

Technical Field

[0001] The utility model relates to the field of geotechnical engineering monitoring, in particular to an inclinometer installation protection device. Background Technique

[0002] An inclinometer is an in-situ monitoring instrument for measuring the inclination angle and azimuth angle of a borehole. Abroad, in the 1950s, inclinometers were used for in-situ monitoring of geotechnical engineering such as earth-rock dams, roadbeds, slopes, and tunnels. In China, since the 1980s, inclinometers produced in the United States, Japan, the United Kingdom and other countries have been introduced to conduct in-situ monitoring of some major geotechnical engineering projects, and good results have been achieved. Subsequently, some related research institutions developed intelligent inclinometers such as resistance strain type, accelerometer type and electronic meter type. All kinds of inclinometers are widely used in the fields of water conservancy and hydropower, mineral metallurgy, transportation and urban construction geotechnical engineering, and play an important role in ensuring the design, construction and use safety of geotechnical engineering.

[0003] The utility model patent with the publication number CN213397056U discloses an inclinometer, which includes a moving device, a supporting device, a rotating device, a detecting device and a collecting device. The moving device includes legs, the supporting device includes a bottom plate and a supporting shaft, the upper surfaces of several legs are welded to the lower surface of the bottom plate, the rotating device includes a disc, a cable and a plug, the disc is rotationally matched with the supporting shaft, the detecting device includes a detecting cylinder, one end of the detecting cylinder is connected to one end of the cable, the collecting device includes a reading instrument, the lower surface of the reading instrument is connected to the upper surface of the bottom plate, a jack is arranged on one surface of the reading instrument, and the plug is slidably matched with the jack. In this utility model, by setting the supporting shaft, the disc and the connecting column, the cable can be conveniently stored, saving the storage time, and solving the problem that the cable of the existing inclinometer is inconvenient to store. By setting the display screen and the operator, the device can calculate the inclination more intelligently.

[0004] In the above technical solution, the cable is spirally wound on the rotating device, so there will be different cable pulling angles during the retracting and extending process, resulting in the cable being easily physically damaged by pulling, twisting or excessive bending, especially when operating in complex terrain or harsh environments. In some cases, the cable may even be pulled and broken, affecting continuous measurement. Moreover, the pulling end of the cable is directly connected to the detecting device, and the pulled cable is in frictional contact with the ground, which is likely to cause cable damage or breakage over time. Once the cable breaks or snaps, it will not only result in the loss or error of measurement data, but also may cause the equipment to stop, seriously affecting the project progress and the accuracy and reliability of the measurement work. Therefore, further improvement is needed. Content of the Utility Model

[0019] Compared with the prior art, the beneficial effects of the technical solution of the present utility model are as follows:

[0020] By installing a cable protection device on the bottom plate in the present utility model, namely a sliding seat fixed on the bottom plate, a chute formed on the sliding seat, and a sliding mechanism (lower slider + upper bracket) slidably engaged with the chute. A rotating column is arranged inside the bracket. The pulling end of the cable (referring to the control cable of the inclinometer in this article) is movably supported on the rotating column inside the bracket and extends out of the bracket and then connected to the detection component. When a person pulls the cable during the measurement operation, the sliding mechanism is driven by the cable to slide along the chute with the pulling angle of the cable, adapting to different winding positions of the cable on the coiling device, which is beneficial to avoiding physical damages such as the cable being pulled, twisted or excessively bent.

[0021] By arranging rollers on the left and right side walls of the lower horizontal part of the slider that are in rolling cooperation with the inner side wall of the chute in the present utility model, the smoothness of the slider in the chute is improved, avoiding jamming and affecting the cable pulling.

[0022] In this utility model, the winding reel is threadedly connected to the limiting circular plate through the support plate at one end, ensuring the stability of the winding reel during operation, preventing the cable from being unevenly stressed and breaking due to vibration or loosening, and improving the operation reliability of the device in harsh environments. In addition, the annular turning handles designed at both ends of the winding reel not only make the operation of winding and unwinding the cable more convenient, but also improve the operation comfort through an ergonomic design, reducing the physical consumption of the operator during long-term operation.

[0030] The drawings are only for illustrative purposes and should not be construed as a limitation of this patent;

[0031] To better illustrate this embodiment, some components in the drawings are omitted, enlarged, or reduced, and do not represent the dimensions of the actual product;

[0032] For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0033] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and defined, the terms "arrangement" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be said that there is a connection inside two components.

The orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "front", "rear", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0034] The technical solution of the present utility model will be further described below in conjunction with the drawings and embodiments.

[0035] As Figure 1 、 Figure 2 shown is an inclinometer installation protection device according to an exemplary embodiment of the present utility model, which includes a rectangular movable bottom plate 100 and a wire coiling device 200. The bottom plate 100 can be conveniently moved on the ground of various measurement environments through four casters installed at the four corners of its bottom surface, ensuring the portability and flexibility of the use of the inclinometer, and facilitating the reduction of possible damage to the cable during the movement process. The wire coiling device 200 is installed in the middle of the bottom plate 100, and its axis is parallel to the short side direction of the bottom plate. A cable 320 is spirally wound thereon. The two ends of the cable 320 are respectively used to connect the detection component 310 and the acquisition component 330 of the inclinometer, and the acquisition component 330 is installed on the bottom plate 100. Here, the detection component, the cable, and the acquisition component are all basic configurations of the inclinometer and are common knowledge in the art, so their structures and connections will not be described in detail here. For details, reference can be made to the prior art.

[0036] The inclinometer installation protection device further includes a cable protection device 400 installed on the bottom plate 100, and the wire coiling device 200 is located between the cable protection device 400 and the acquisition component 330. The cable protection device 400 includes a sliding seat 410 extending parallel to the axis of the wire coiling device 200. A chute 411 is opened in the sliding seat 410 along its extending direction. A sliding mechanism is slidably connected in the chute 411. The pulling end of the cable 320 is movably supported and passes through the inside of the sliding mechanism to connect the detection component 310. That is to say, the pulling end of the cable is connected to the detection component after passing through the cable protection device. In this way, when a person pulls the cable 320 during the measurement operation, the sliding mechanism can slide along the chute 411 with the pulling angle of the cable, adapting to different winding positions of the cable 320 on the wire coiling device 200.

[0037] As Figure 2 , Figure 3 shown, the sliding mechanism includes a slider 420 and a bracket 430. The slider 420 is slidably connected to the chute 411. The bracket 430 includes two vertical plates relatively fixed to the top surface of the slider 420, and the two vertical plates are arranged at intervals in the front and rear directions along the sliding direction of the slider. Optionally, a base plate is connected between the bottoms of the two vertical plates to form a concave frame structure, and the concave frame structure is fixed to the top surface of the slider 420 through the base plate to ensure the stable fixation of the bracket 430. A rotating column 440 is rotatably connected between the two vertical plates. The axis of the rotating column 440 is parallel to the axis of the wire coiling device 200. The pulling end of the cable 320 is movably supported on the rotating column 440 and extends out between the two vertical plates.

[0038] As Figure 3 , Figure 4 shown, a transverse cover plate 431 is further installed between the two vertical plates. The transverse cover plate 431 is located above the rotating column 440, and one end is hinged to the top of one of the vertical plates, such as by a hinge, and the other end is detachably fixed to the top of the other vertical plate. For example, threaded connection, snap connection, lock connection, etc. can be adopted. In this embodiment, a connecting portion 4311 extends and protrudes from the other end of the transverse cover plate 431, and a concave connecting groove 432 is formed on the top of the corresponding vertical plate. Rotate the transverse cover plate 431 until the connecting portion 4311 is fitted and embedded in the connecting groove 432, and then fix it through the connecting holes respectively opened in the connecting portion and the connecting groove by a bolt 433 (a through hole is opened in the connecting portion 4311, threaded holes and through holes are respectively opened on the two groove walls of the connecting groove 432, the bolt 433 is sequentially inserted into the through hole of the connecting groove and the through hole of the connecting portion, and is screwed into the threaded hole of the connecting groove by thread matching, and the tail end is screwed with a nut for fixation). In this way, the transverse cover plate 431 and the bracket 430 can be effectively fixedly connected to form a rectangular frame structure (the rotating column 440 is located therein), avoiding the transverse cover plate 431 from being opened due to loosening or displacement during operation, and the pulling end of the cable 320 falling out of the bracket 430, ensuring the stable and reliable cable protection effect of the cable protection device 400.

[0039] In some embodiments, the middle circumferential surface of the rotating column 440 is a cable support position 441, and the radial dimension of the rotating column gradually increases from the cable support position to both ends. In this way, the arc-shaped curved surface of the rotating column is used to support the pulling end of the cable, which can avoid excessive bending of the cable; in addition, the gradually increasing column diameter at both ends has a certain limiting effect on the pulling end of the cable (in the axial direction of the rotating column), which can avoid contact between the cable and the bracket, reduce wear, and is conducive to the cable driving the slider to slide adaptively, reducing excessive pulling of the cable during the measurement process.

[0040] In some embodiments, the outer contour of the slide 410 is a cuboid; the slide groove 411 is an inverted T-shaped groove, and the notch is opened on the upper surface of the slide 410; the slider 420 is an I-shaped block, and its vertical part and lower horizontal part are slidably matched in the slide groove 411, and the upper horizontal part is slidably matched on the upper surface of the slide 410. The structure is simple and easy to process and shape.

[0041] Furthermore, the left and right side walls of the lower transverse portion along the sliding direction of the slider are rollingly matched with the corresponding side walls in the slide groove 411 through the rollers 421. Specifically, the lower transverse portion is provided with a left-right through-accommodation cavity, and a plurality of rollers 421 are installed in the accommodating cavity, for example, four rollers are symmetrically installed in the accommodating cavity, two of which are partially exposed outside the through-opening on the left side of the accommodating cavity and rollingly matched with the corresponding side walls in the slide groove, and the other two rollers are partially exposed outside the through-opening on the right side of the accommodating cavity and rollingly matched with the corresponding side walls in the slide groove.

[0042] like Figure 5 As shown, in some embodiments, the wire winding device 200 includes a winding drum 210 and two support plates 220 symmetrically installed on the base plate 100, and the two support plates 220 are provided with corresponding circular mounting holes. The outer surfaces of the disks at both ends of the winding drum 210 are respectively fixed with rotating shafts that rotate with the mounting holes along the axis of the winding drum. After the two rotating shafts pass through the corresponding mounting holes respectively, the ends are fixedly connected to the limiting circular plates 230, and the winding drum 210 is axially limited by the limiting circular plates 230 to ensure that the rotational connection between the winding drum and the two support plates is stable and reliable.

[0043] Furthermore, one of the plates 220 has a stop screw hole 221 on the outside of the mounting hole, and the corresponding limiting circular plate 230 is provided with a plurality of insertion holes 231 to cooperate with the stop screw 240 to stop the winding drum 210 from rotating, so as to prevent the winding drum from accidentally loosening or shaking due to vibration (such as uneven ground) or external force, and to avoid forced pulling of the cable in an unstable state, thereby reducing the risk of cable breakage. Specifically, when it is necessary to prevent the winding drum 210 from accidentally rotating during operation, the winding drum 210 is slightly rotated as needed to align one of the insertion holes 231 with the stop screw hole 221, and then the stop screw 240 is inserted into the aligned insertion hole 231, and screwed into the stop screw hole 221 with threaded engagement, and the tail end is screwed with a nut to fix it.

[0044] In some embodiments, a plurality of fixed rods 211 are connected between the inner sides of the discs at both ends of the winding drum 210, and the plurality of fixed rods 211 are evenly distributed on the outer side of the winding roller of the winding drum 210. The cable 320 is spirally wound on the circular surface formed by the plurality of fixed rods 211. In this way, compared with winding the cable directly on the winding roller, the winding diameter is increased, which can avoid excessive squeezing between the cables and is also convenient for personnel to operate.

[0045] In some embodiments, annular turning handles 212 are installed on the circumferences of the disks at both ends of the take-up reel 210, facilitating the easy rotation and operation of the take-up reel by personnel to wind and unwind the cable, thus improving the convenience and comfort of the operation.

[0046] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
