Description

Technical Field

[0001] The present invention relates to the technical field of slope detection, and in particular to a creep-type landslide warning and detection device. Background Art

[0002] Landslides on slopes are highly hazardous, and corresponding detection devices need to be installed on slopes prone to landslides for landslide detection and warning to ensure timely discovery and subsequent treatment in the event of a landslide.

[0003] After retrieval, a patent with the Chinese patent publication number CN111739260B discloses a landslide warning device for bauxite loess geological slopes, including a first insertion rod, a first mounting plate, a first connecting rod, a support rod, an arc-shaped track, a self-powered contact-type remote signal transmitter, etc.; the first insertion rod is inserted at the top of the slope, the top of the first insertion rod is provided with a first mounting plate, the right side of the first mounting plate is provided with a first connecting rod, and the right side of the top of the first connecting rod is provided with two support rods, and an arc-shaped track is connected between the left and right support rods.

[0004] The above patent has the following deficiencies: it uses the linear displacement during a landslide to drive the swing of a rotary swing rod to achieve detection and warning. However, since the device is fixed outdoors for a long time, on the one hand, the rotary swing rod may not be able to be rotated and started due to the action of the wind, and on the other hand, it is relatively exposed, and there will be situations such as sediment erosion outdoors for a long time, resulting in jamming, thus reducing the reliability.

[0005] Therefore, the present invention proposes a creep-type landslide warning and detection device. Summary of the Invention

[0006] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose a creep-type landslide warning and detection device.

[0007] To achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A creep-type landslide warning and detection device includes a fixing frame at the bottom of the slope and the slope surface, and a detection and warning part arranged at the top of the slope. One side of the fixing frame is fixed with a connecting steel strand, and the other end of the connecting steel strand is in transmission cooperation with the detection and warning part;

[0009] The detection and warning part includes a housing fixed at the top of the slope and a threaded multi-stage lifting assembly arranged inside the housing;

[0010] The threaded multi-stage lifting assembly includes a fixed housing, a plurality of lifting housings sequentially arranged inside the fixed housing, a main screw rod, and a plurality of externally threaded cylinders sequentially arranged. The fixed housing is connected to the lifting housing, the lifting housing to the lifting housing, the externally threaded cylinder to the main screw rod, and the externally threaded cylinder to the externally threaded cylinder through the clearance fit connection of a key and a keyway; the main screw rod is rotatably connected to the bottom inner wall of the fixed housing, and a winding drum is fixed to the outer wall of the bottom of the main screw rod; the other end of the connecting steel strand is wound around the outer wall of the winding drum.

[0011] The number of the externally threaded cylinders is one less than the number of the lifting housings, and a plurality of the externally threaded cylinders are respectively rotatably connected to the inner walls of the lifting housings except the middlemost one. Inner threaded sleeves are fixedly clamped to the inner side walls of the bottoms of all the lifting housings, and the inner threaded sleeves are threadedly connected to the outer walls of an externally threaded cylinder adjacent to the inner side of the inner threaded sleeve, and the inner threaded sleeve at the bottommost is threadedly connected to the outer wall of the main screw rod.

[0012] Preferably: An audible alarm is fixed to the top of the innermost lifting housing. A remote communicator for communicating with a monitoring personnel or a monitoring base station is arranged on the top of the audible alarm, and a protective housing with a mirror-like appearance is fixed to the outer wall of the lifting housing on the outer side of the remote communicator and the audible alarm.

[0013] Further: Sound transmission holes are formed in the side walls of the protective housing, and a cover is fixed to the outer wall of the top of the protective housing. The cover is in sealing cooperation with the top stop of the fixed housing.

[0014] On the basis of the foregoing solution: The detection and warning part and the fixed frame are both fixedly connected to the slope through multiple groups of fixing components. The fixing components include side ears fixed to the side walls of the detection and warning part and the fixed frame and inserting rods movably inserted inside the side ears. A limiting block larger than or equal to the size of the top of the side ear is fixed to the top of the inserting rod. A wrench opening is arranged on the inner wall of the top of the limiting block, and anti-slip lines are arranged on the outer wall of the top of the limiting block.

[0015] A better solution in the foregoing solution is: A main power supply, an integrated chip, and a backup power supply are respectively fixed to the inner wall of the outer housing. The main power supply and the backup power supply are connected to supply power to the integrated chip, and the integrated chip is controlled to be connected to the remote communicator and the audible alarm and controls the opening and closing of the remote communicator and the audible alarm.

[0016] As a further solution of the present invention: A set of guiding and state sensing mechanisms for guiding and state monitoring of the connecting steel strand are respectively arranged on one side of the detection and warning part and the fixed frame, and the detection and warning part further includes a clamp-type locking assembly arranged inside the outer housing and used for pulling and locking the connecting steel strand.

[0017] Meanwhile, the guiding and state sensing mechanism includes a swing frame and at least two groups of pulleys rotatably connected to the inner side of the swing frame. Each group of pulleys is symmetrically arranged in two, and the connecting steel strand passes through the middle of the two pulleys. One end of the swing frame is rotatably connected to the outer shell and the fixing frame through a connecting shaft.

[0018] As a preferred embodiment of the present invention: Pressing and closing switches are fixedly embedded in the inner walls of the outer shell and the fixing frame on both sides of the swing frame. Among the four pressing and closing switches, classified according to their orientation relative to the swing frame, they are respectively:

[0019] The first left and the second left installed on the outer shell;

[0020] The first right and the second right installed on the fixing frame.

[0021] Meanwhile, the clamp-type locking assembly includes a chassis fixed inside the outer shell or fixed to the slope, and a clamping arm rotatably connected to the top of the chassis. One end of the chassis and the clamping arm are respectively located above and below the connecting steel strand. The other ends of the chassis and the clamping arm are respectively provided with an opposing electromagnet and a permanent magnet. The permanent magnet is fixed to the lower side of the clamping arm, the electromagnet is fixed to the upper side of the chassis, and the opposite sides of the electromagnet and the permanent magnet have the same magnetic poles.

[0022] As a more optimal solution of the present invention: The first left and the first right, and the second left and the second right among the pressing and closing switches are respectively connected in series to form two parallel paths and then connected in series to the power supply circuit of the electromagnet.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. In the present invention, on the one hand, the remote communicator, the protective shell, and the sound alarm for warning are driven in a lifting manner, so that when there is no landslide, a relatively enclosed space is formed with the outer shell, which will not be eroded by sediment, solving the jamming problem, and its longitudinal movement will not cause the situation of moving against the wind. On the other hand, by using the cooperation of the multi-stage lifting shell and the multi-stage external thread cylinder and the internal thread sleeve, its lifting is multi-stage lifting, so that the longitudinal dimension of the entire detection and warning part in the non-warning state can be smaller, reducing the windward area, preventing the fixation of the detection and warning part to the slope from being loosened by the wind. At the same time, the multi-stage lifting adopts a threaded fit, which is more compact than the hydraulic multi-stage lifting structure and the composition of each stage is simple, and the production and manufacturing costs are greatly reduced.

[0025] 2. In the present invention, by providing sound-permeable holes, it can achieve a sound-permeable effect, increase the warning range, and through the setting of a remote communicator, it can also realize the remote alarm function. At the same time, the protective shell is both a protective shell for the remote communicator and the sound alarm, and its outer surface is mirror-like, serving as a light alarm function. Meanwhile, by setting a cover, it can cooperate with the top of the fixed shell to be closed when not in alarm, making the top of the detection and warning part form a closed state, preventing sundries such as sediment from entering, further preventing situations such as jamming and erosion, and increasing reliability.

[0026] 3. In the present invention, it is fixed by multiple groups of fixing components, and the fixing components are composed of split side ears and insertion rods, so as to realize the carrying and transportation of the module. Meanwhile, spiral sheets are arranged on the outer side of the insertion rods, which can increase the mutual fixing force between the device and the slope and prevent loosening. At the same time, wrench openings and anti-slip patterns are set, and multiple forms can be used for fixing to achieve the functions of labor-saving and convenience.

[0027] 4. In the present invention, based on the characteristics that the connecting steel strands are in a straight line or "V" shape in case of landslide and accidental touch, combined with the electromagnetic drive locking of the clamp-type locking component, on the one hand, it can lock the connecting steel strands in case of accidental touch to prevent accidental triggering of the landslide alarm. On the other hand, the entire process realizes trigger recognition by relying on a simple push-button closing switch and a clever circuit combination structure. The combination structure is relatively simple while ensuring accuracy, and both the manufacturing cost and the usage cost are relatively low. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0037] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0038] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0039] Embodiment 1:

[0040] A creep - type landslide warning detection device, as Figure 1 - Figure 8 shown, includes a slope 1, a fixing frame 4 at the bottom of the slope surface, and a detection and warning part 2 arranged at the top of the slope 1. One side of the fixing frame 4 is fixed with a connecting steel strand 3, and the other end of the connecting steel strand 3 is in transmission cooperation with the detection and warning part 2.

[0041] The detection and warning part 2 includes an outer housing 6 fixed at the top of the slope 1 and a threaded multi - stage lifting component 7 arranged inside the outer housing 6;

[0042] The threaded multi-stage lifting assembly 7 includes a fixed housing 13, a plurality of lifting housings 14 sequentially arranged inside the fixed housing 13, a main screw rod 21, and a plurality of outer threaded cylinders 19 sequentially arranged. The fixed housing 13 and the lifting housing 14, the lifting housing 14 and the lifting housing 14, the outer threaded cylinder 19 and the main screw rod 21, and the outer threaded cylinder 19 and the outer threaded cylinder 19 are connected by the clearance fit of a key and a keyway, which ensures that the two connected components can only slide axially relative to each other and cannot rotate relative to each other. The main screw rod 21 is rotatably connected to the bottom inner wall of the fixed housing 13, and a winding drum 23 is fixed to the outer wall of the bottom of the main screw rod 21. The other end of the connecting steel strand 3 is wound around the outer wall of the winding drum 23.

[0043] The number of the outer threaded cylinders 19 is one less than the number of the lifting housings 14, and a plurality of the outer threaded cylinders 19 are respectively rotatably connected to the inner walls of the lifting housings 14 except the middlemost one. Inner threaded sleeves 20 are fixedly clamped to the inner side walls of the bottoms of all the lifting housings 14, and the inner threaded sleeves 20 are threadedly connected to the outer walls of one outer threaded cylinder 19 adjacent to the inner side of the inner threaded sleeves 20. And the inner threaded sleeve 20 at the bottommost is threadedly connected to the outer wall of the main screw rod 21.

[0044] An audible alarm 18 is fixed to the top of the innermost lifting housing 14. A remote communicator 16 for communicating with monitoring personnel or a monitoring base station is arranged at the top of the audible alarm 18. And a protective housing 17 fixed to the outer wall of the lifting housing 14 and having a mirror-like appearance is arranged outside the remote communicator 16 and the audible alarm 18.

[0045] When in use, when a landslide occurs, the fixed frame 4 will descend, thereby pulling the connecting steel strand 3. The connecting steel strand 3 drives the winding drum 23 to rotate, thereby driving the main screw rod 21 to rotate. When the main screw rod 21 rotates, on the one hand, it will make the outermost inner threaded sleeve 20 drive the outermost lifting housing 14 to rise through the threaded connection effect. On the other hand, it will also drive all the outer threaded cylinders 19 to rotate. Therefore, the outermost outer threaded cylinder 19 has a movement of rotating and rising with the lifting housing 14. Then, by using the rotation of the outer threaded cylinder 19, the second outermost inner threaded sleeve 20 and the lifting housing 14 are made to rise, which in turn drives the outer threaded cylinder 19 on the next inner side to rotate and rise. Thus, the function of the outer threaded cylinder 19 and the inner threaded sleeve 20 is utilized again for transmission, realizing the multiple-speed rise of the innermost lifting housing 14.

[0046] On the one hand, this device drives the remote communicator 16, the protective case 17, and the sound alarm 18 for warning in a lifting manner. Thus, when there is no landslide, it forms a relatively enclosed space with the outer shell 6 and will not be eroded by sediment, solving the jamming problem. Moreover, since it moves longitudinally, there will be no situation of moving against the wind. On the other hand, by using the cooperation of the multi-stage lifting shell 14 with the multi-stage external thread cylinder 19 and the internal thread sleeve 20, its lifting is in a multi-stage manner, so that the longitudinal storage dimension of the entire detection and warning part 2 in the non-warning state can be smaller, reducing the windward area, preventing the fixation of the detection and warning part 2 to the slope 1 from being loosened by the wind. At the same time, the multi-stage lifting adopts a threaded fit, which is more compact than the hydraulic multi-stage lifting structure and the composition of each stage is simple, greatly reducing the production and manufacturing costs.

[0047] Sound transmission holes 22 are provided on the side wall of the protective case 17, and a cover 15 is fixed to the outer wall of the top of the protective case 17. The cover 15 is in sealing cooperation with the top stop of the fixed case 13.

[0048] In this device, by providing the sound transmission holes 22, it can achieve a sound transmission effect and increase the warning range. And through the setting of the remote communicator 16, the remote alarm function can also be realized. At the same time, the protective case 17 is both a protective case for the remote communicator 16 and the sound alarm 18, and its appearance is mirror-like, playing a light alarm function. At the same time, by providing the cover 15, it can cooperate with the top of the fixed case 13 to be closed when there is no alarm, making the top of the detection and warning part 2 form a closed state, preventing sundries such as sediment from entering, further preventing situations such as jamming and erosion from occurring, and increasing the reliability.

[0049] To solve the fixation problem; as Figure 8 As shown, both the detection and warning part 2 and the fixing frame 4 are fixedly connected to the slope 1 through multiple fixing components. The fixing components include side ears 32 fixed to the side walls of the detection and warning part 2 and the fixing frame 4 and insertion rods 36 movably inserted inside the side ears 32. A limiting block 35 with a size greater than or equal to the top size of the side ear 32 is fixed to the top of the insertion rod 36. A wrench opening 33 is provided on the inner wall of the top of the limiting block 35, and an anti-slip pattern 34 is provided on the outer wall of the top of the limiting block 35.

[0050] A spiral piece 11 is fixed to the outer wall of the insertion rod 36, and the longitudinal section profile of the spiral piece 11 is in an inverted conical shape.

[0051] The main power supply 8, the integrated chip 9, and the backup power supply 10 are respectively fixed to the inner wall of the outer shell 6. The main power supply 8 and the backup power supply 10 are connected to supply power to the integrated chip 9, and the integrated chip 9 is controlled to be connected to the remote communicator 16 and the sound alarm 18 and controls the opening and closing of the remote communicator 16 and the sound alarm 18.

[0052] During fixation, the detection and warning part 2 and the fixing frame 4 can be positioned first and then placed on the surface of the slope 1. Then, hold the limiting block 35 by hand and insert the inserting rod 36 through the side ear 32 and into the slope 1. After a part of the spiral piece 11 is inserted into the inserting rod 36, rotate the limiting block 35 through the anti-slip lines 34, and use the thread of the spiral piece 11 to achieve self-tapping entry. At the same time, when the rotation resistance is large, the inserting rod 36 can be rotated by a wrench in cooperation with the wrench opening 33 until the bottom of the limiting block 35 fits against the top of the side ear 32.

[0053] This device is fixed by multiple groups of fixing components, and the fixing components are composed of the split side ear 32 and the inserting rod 36, so that the module can be carried and transported. And a spiral piece 11 is arranged on the outer side of the inserting rod 36, which can increase the mutual fixing force between the device and the slope 1 and prevent loosening. At the same time, the wrench opening 33 and the anti-slip lines 34 are provided, and multiple forms can be used for fixing to achieve the function of labor saving and convenience.

[0054] During the fixation of this embodiment, the detection and warning part 2 and the fixing frame 4 can be positioned first and then placed on the surface of the slope 1. Then, hold the limiting block 35 by hand and insert the inserting rod 36 through the side ear 32 and into the slope 1. After a part of the spiral piece 11 is inserted into the inserting rod 36, rotate the limiting block 35 through the anti-slip lines 34, and use the thread of the spiral piece 11 to achieve self-tapping entry. At the same time, when the rotation resistance is large, the inserting rod 36 can be rotated by a wrench in cooperation with the wrench opening 33 until the bottom of the limiting block 35 fits against the top of the side ear 32. When in use, in case of a landslide, the fixing frame 4 will descend, thereby pulling the connecting steel strand 3, driving the winding drum 23 to rotate through the connecting steel strand 3, and then driving the main screw rod 21 to rotate. When the main screw rod 21 rotates, on the one hand, it will drive the outermost inner thread sleeve 20 to drive the outermost lifting shell 14 to rise through the thread connection, and on the other hand, it will also drive all the outer thread cylinders 19 to rotate. Therefore, the outermost outer thread cylinder 19 has the movement of rotating and rising along with the lifting shell 14. Then, by using the rotation of this outer thread cylinder 19, the second outermost inner thread sleeve 20 and the lifting shell 14 are made to rise, which in turn drives the outer thread cylinder 19 on the inner side of the second outermost side to rotate and rise. Thus, the action of the outer thread cylinder 19 and the inner thread sleeve 20 is used for transmission again to realize the multiple-speed rise of the innermost lifting shell 14. The lifting shell 14 drives the remote communicator 16, the protective shell 17, and the sound alarm 18 to rise synchronously. The sound alarm 18 emits a beep and at the same time the remote communicator 16 conducts remote communication for alarm, and the mirror surface of the protective shell 17 can also conduct optical alarm, which is also convenient for searching and positioning.

[0055] Embodiment 2:

[0056] A creep-type landslide early warning detection device, such as Figure 1 - Figure 8As shown, when the entire device is set up in the wild during actual use, people or other animals may occasionally move on the slope surface of the slope 1. If a person or other animal touches the connecting steel strand 3, it will also cause the connecting steel strand 3 between the detection and warning part 2 and the fixing frame 4 to move, thereby pulling the connecting steel strand 3 at the transmission and cooperation part of the detection and warning part 2. At this time, false warnings of landslides will occur. Based on this; the following improvements are made in this embodiment on the basis of Embodiment 1: A set of guiding and state sensing mechanisms 5 for guiding and monitoring the state of the connecting steel strand 3 are respectively arranged on one side of the detection and warning part 2 and the fixing frame 4, and the detection and warning part 2 further includes a clamp type locking component 12 arranged inside the outer shell 6 and used for locking and stopping the pulling of the connecting steel strand 3.

[0057] The guiding and state sensing mechanism 5 includes a swing frame 29 and at least two groups of pulleys 28 rotatably connected inside the swing frame 29. Each group of pulleys 28 is symmetrically arranged in two. The connecting steel strand 3 passes through the middle of the two pulleys 28. One end of the swing frame 29 is rotatably connected to the outer shell 6 and the fixing frame 4 through a connecting shaft 30.

[0058] Pressing and closing switches 31 are fixedly embedded on the inner walls of the outer shell 6 and the fixing frame 4 on both sides of the swing frame 29. Among the four pressing and closing switches 31, classified according to the orientation relative to the swing frame 29, they are respectively:

[0059] Installed at the left one and left two of the outer shell 6;

[0060] Installed at the right one and right two of the fixing frame 4.

[0061] The clamp type locking component 12 includes a chassis 26 fixed inside the outer shell 6 or fixed to the slope 1, and a clamping arm 27 rotatably connected to the top of the chassis 26. One end of the chassis 26 and the clamping arm 27 are respectively located above and below the connecting steel strand 3. The other ends of the chassis 26 and the clamping arm 27 are respectively provided with an opposing electromagnet 25 and a permanent magnet 24. The permanent magnet 24 is fixed to the lower side of the clamping arm 27, the electromagnet 25 is fixed to the upper side of the chassis 26, and the opposite sides of the electromagnet 25 and the permanent magnet 24 have the same magnetic poles.

[0062] Among the pressing and closing switches 31, the left one and the right one, and the left two and the right two are respectively connected in series to form two parallel paths and then connected in series to the power supply circuit of the electromagnet 25.

[0063] When this embodiment is in use, during a landslide, since there is no external force acting on the middle part of the connecting steel strand 3, the connecting steel strand 3 between the detection and warning part 2 and the fixing frame 4 must be in a straight state. If the straight connecting steel strand 3 is parallel to the slope section of the slope 1, all four pressing and closing switches 31 are in the off state, the electromagnet 25 is not activated, and the connecting steel strand 3 can be freely pulled. If the straight connecting steel strand 3 is not parallel to the slope section of the slope 1, there will be a lateral displacement of the detection and warning part 2 and the fixing frame 4 relative to the slope. Since the detection and warning part 2 and the fixing frame 4 are located at both ends of the connecting steel strand 3 respectively, their inclination directions relative to the connecting steel strand 3 are opposite, similar to the characteristics of a parallelogram. At this time, the left one and the right two or the left two and the right one are squeezed and conducted by the swing frame 29, but the power supply path of the electromagnet 25 will not be conducted, and the connecting steel strand 3 can still be freely pulled. However, when a person or an animal accidentally touches the connecting steel strand 3, the connecting steel strand 3 between the detection and warning part 2 and the fixing frame 4 will be in a "V" shape, which will cause the left one and the left two or the right one and the right two to be squeezed and conducted by the swing frame 29. At this time, the power supply of the electromagnet 25 is conducted, and the electromagnet 25 generates the same magnetic field as the permanent magnet 24. As a result, the permanent magnet 24 is repelled and moves upward, and then the base frame 26 and the clamping arm 27 at the other end, which act as a lever, clamp and lock the connecting steel strand 3, and the connecting steel strand 3 cannot be stretched and cannot trigger the landslide alarm.

[0064] This device, based on the characteristics of the connecting steel strand 3 being in a straight line or "V" shape in the case of landslides and accidental touches, combined with the electromagnetic drive lock of the clamp-type locking component 12, can, on the one hand, lock the connecting steel strand 3 during accidental touches to prevent accidental triggering of the landslide alarm. On the other hand, the entire process realizes trigger recognition relying on simple pressing and closing switches 31 and a clever circuit combination structure. The combination structure is relatively simple while ensuring accuracy, and both the manufacturing cost and the use cost are relatively low.

[0065] The above is only a preferred specific embodiment 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 inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
