Description

Technical Field

[0001] This utility model relates to the field of natural disaster monitoring technology, specifically to a traffic natural disaster monitoring and early warning instrument. Background Technology

[0002] Natural disaster monitoring involves using sensor networks and data acquisition technologies to continuously track abnormal changes in the natural environment, such as geology and meteorology, in order to identify early warning signs of disasters. Based on this, the traffic natural disaster monitoring and early warning instrument is specifically designed for disaster risks around transportation facilities such as highways and railways. It integrates monitoring methods with early warning mechanisms, enabling it to detect dangerous signs such as landslides and collapses that may block traffic in real time and issue timely warnings. Displacement monitoring instruments deployed on mountain slopes are a specific implementation of this type of early warning system for landslide monitoring.

[0003] Existing displacement monitoring devices typically consist of a mounting pole, a monitor, a control cabinet, and an audible and visual alarm. The monitor is fixed to the top of the pole, while the control cabinet and alarm are located on opposite sides of the pole. During use, the monitor collects displacement data and transmits it to the control cabinet for threshold comparison. Once the limit is exceeded, an audible and visual alarm is triggered. However, existing monitors are usually rigidly mounted on the top of the pole using fixed brackets. The installation angle is determined during construction and cannot be flexibly adjusted according to the terrain or vegetation obstruction. This makes it difficult to align the sensor with the optimal monitoring position in rugged mountainous areas or complex slopes, reducing the representativeness of the data collected. Furthermore, calibration requires disassembly and reinstallation, making the process cumbersome. Utility Model Content

[0004] The purpose of this utility model is to provide a traffic natural disaster monitoring and early warning instrument, which solves the problem that in existing displacement monitoring instruments, the monitor is rigidly installed on the top of the pole by a fixed bracket, which makes it impossible to flexibly adjust the installation angle according to the site terrain conditions, resulting in insufficient data collection representativeness and low on-site deployment efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a traffic natural disaster monitoring and early warning device, comprising a mounting rod with side plates on both sides, a base on the lower surface of the mounting rod, an angle adjustment structure at the top of the mounting rod, a monitor mounted on the upper end of the angle adjustment structure, a control cabinet mounted on the upper surface of one of the side plates, and an audible and visual alarm mounted on the upper surface of the other side plate. The angle adjustment structure includes a mounting base, which is fixedly mounted on the upper surface of the mounting rod. A connecting seat is provided at the upper end of the mounting base, and the monitor is fixedly mounted on the upper surface of the connecting seat. A worm gear is provided on the upper surface of the mounting base, and two connecting plates are mounted on the lower surface of the connecting seat. A worm is rotatably connected between the two connecting plates, and the worm meshes with the worm wheel.

[0007] Furthermore, one end of the worm gear passes through one of the connecting plates and is equipped with a handle. Both ends of the mounting base are provided with sliding grooves. The lower surface of the connecting base is provided with two connecting rods. The two connecting rods are slidably connected inside the corresponding sliding grooves. Nuts are threadedly connected to the outer sides of the two connecting rods.

[0008] Furthermore, the mounting base has scale lines on its outer side, and the connecting base has a pointer mounted on its outer side, with the pointer located at the upper end of the scale lines.

[0009] Furthermore, the upper end of the mounting rod is provided with a protective cover, the upper surface of the mounting rod is provided with four mounting slots, the lower end of the protective cover is fixedly connected with four support rods, the four support rods are all fitted into the interior of the corresponding mounting slots, and a fixing structure is provided between each pair of adjacent support rods.

[0010] Furthermore, the fixing structure includes a mounting block, the upper surface of which has a groove, and two sliding plates are slidably connected inside the groove. A spring is fixedly installed between the two sliding plates, and a fixing block is installed at the other end of each of the two sliding plates.

[0011] Furthermore, a cover plate is installed on the upper surface of the mounting block, and an opening is provided in the middle of the cover plate. Two levers are slidably connected inside the opening, and both levers are fixedly installed on the upper surface of the corresponding slide plate. A placement groove is also provided on the upper surface of the mounting rod, and the mounting block is fitted inside the placement groove. A fixing groove is provided on one side of the support rod, and one end of the fixing block passes through the mounting block and the mounting rod in sequence and is fitted inside the fixing groove.

[0012] Furthermore, a sealing block is installed inside the opening, and the sealing block is located between the two levers.

[0013] This utility model has the following beneficial effects:

[0014] (1) This utility model drives the worm to rotate by rotating the handle. The worm drives the connecting seat to swing around the horizontal axis through the worm wheel, realizing the stepless adjustment of the monitor's pitch angle. This allows the monitor to be flexibly adjusted to the optimal monitoring position according to the undulation of the terrain and the obstruction of vegetation. At the same time, the meshing of the worm and the worm wheel has a self-locking characteristic, which can keep the monitor's pitch angle stable after the angle adjustment is completed, and avoid deviation due to its own weight or wind force. This solves the problem in the existing displacement monitor that the monitor is rigidly installed on the top of the pole by a fixed bracket and the installation angle cannot be flexibly adjusted according to the terrain conditions. This improves the representativeness of data collection and the efficiency of on-site deployment.

[0015] (2) This utility model has a fixed structure, including an installation block, a sliding plate, a spring, a fixing block, a lever, and a sealing block. During installation, the lever is moved in opposite directions to retract the fixing block. After the installation block and the support rod are placed in, the force on the lever is removed. The spring pushes the fixing block to extend and insert it into the fixing groove on the outside of the support rod, thus completing the quick locking and fixing of the protective cover. During disassembly, the sealing block is removed and the lever is moved to remove the fixing block from the fixing groove, and the protective cover can be lifted up. The installation and removal of the protective cover can be completed without the aid of tools. The sealing block closes the opening under the normal use state of the protective cover to prevent external debris from entering the groove, further improving the convenience of maintenance operations.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 As shown, this utility model is a traffic natural disaster monitoring and early warning device, including a mounting rod 1, side plates 101 on both sides of the mounting rod 1, a base 102 on the lower surface of the mounting rod 1, an angle adjustment structure 2 at the top of the mounting rod 1, a monitor 3 installed at the upper end of the angle adjustment structure 2, a control cabinet 4 installed on the upper surface of one side plate 101, and an audible and visual alarm 5 installed on the upper surface of the other side plate 101.

[0027] The mounting rod 1 is vertically installed to support the monitor 3 at a set height. Two side plates 101 are fixedly installed on both sides of the mounting rod 1 to provide a mounting base for the control cabinet 4 and the audible and visual alarm 5. The base 102 is fixedly installed at the lower end of the mounting rod 1 to fix the mounting rod 1 to the ground at the monitoring point. The angle adjustment structure 2 is installed at the top of the mounting rod 1 to adjust the pitch angle of the monitor 3. The monitor 3 is installed at the upper end of the angle adjustment structure 2 to collect slope displacement data. The control cabinet 4 is installed on the upper surface of one of the side plates 101 to receive the displacement data collected by the monitor 3 and perform threshold comparison. The audible and visual alarm 5 is installed on the upper surface of the other side plate 101 to issue an audible and visual alarm signal when the displacement data exceeds the limit.

[0028] The angle adjustment structure 2 includes a mounting base 201, which is fixedly mounted on the upper surface of the mounting rod 1. A connecting base 202 is provided at the upper end of the mounting base 201. The monitor 3 is fixedly mounted on the upper surface of the connecting base 202. A worm gear 203 is provided on the upper surface of the mounting base 201. Two connecting plates 204 are installed on the lower surface of the connecting base 202. A worm 205 is rotatably connected between the two connecting plates 204. The worm 205 is meshed with the worm gear 203.

[0029] The mounting base 201 is fixedly installed on the upper end of the mounting rod 1 to provide a mounting base for the angle adjustment structure 2. The connecting base 202 is set on the upper end of the mounting base 201 and can rotate relative to the mounting base 201 around a horizontal axis. The monitor 3 is fixedly installed on the upper surface of the connecting base 202 and rotates synchronously with the connecting base 202. The worm gear 203 is fixedly installed on the upper surface of the mounting base 201 and remains stationary. The two connecting plates 204 are fixedly installed on the lower surface of the connecting base 202 and extend downward. The worm 205 is rotatably connected between the two connecting plates 204 and rotates around its own axis. The helical teeth of the worm 205 mesh with the external teeth of the worm gear 203. When the worm 205 rotates, it drives the connecting base 202 to swing relative to the worm gear 203 around a horizontal axis, thereby realizing the adjustment of the pitch angle of the monitor 3.

[0030] One end of the worm gear 205 passes through one of the connecting plates 204 and is equipped with a handle 206. Both ends of the mounting base 201 are provided with sliding grooves. The lower surface of the connecting base 202 is provided with two connecting rods 207. Both connecting rods 207 are slidably connected to the inside of the corresponding sliding grooves. Nuts 208 are threadedly connected to the outside of both connecting rods 207.

[0031] The handle 206 is fixedly installed at the extended end of the worm gear 205, allowing the operator to hold it and apply rotational driving force to drive the worm gear 205 to rotate. The slide groove is opened at both ends of the mounting base 201 and extends along an arc trajectory. The connecting rod 207 is fixedly installed on the lower surface of the connecting base 202 and extends downward into the corresponding slide groove. The connecting rod 207 slides along the slide groove to provide guidance and limit the swing range during the swing of the connecting base 202. The nut 208 is threadedly connected to the lower extended end of the connecting rod 207 and is used to tighten it after the angle of the monitor 3 is adjusted, further locking and fixing the connecting base 202 and the mounting base 201.

[0032] The mounting base 201 has a scale line 209 on its outer side, and the connecting base 202 has a pointer 210 on its outer side, with the pointer 210 located at the upper end of the scale line 209.

[0033] The scale line 209 is set along the outer arc surface of the mounting base 201 to indicate the pitch angle value of the monitor 3. The pointer 210 is fixedly installed on the outside of the connecting base 202 and rotates synchronously with the connecting base 202. The pointer 210 points to the corresponding position of the scale line 209 to indicate the current pitch angle during the adjustment process, which is convenient for the operator to adjust and record accurately.

[0034] The upper end of the mounting rod 1 is provided with a protective cover 6. The upper surface of the mounting rod 1 is provided with four mounting slots. The lower end of the protective cover 6 is fixedly connected with four support rods 601. The four support rods 601 are all installed in the corresponding mounting slots. A fixing structure 7 is provided between each pair of adjacent support rods 601.

[0035] The protective cover 6 is located at the upper end of the mounting rod 1 and covers the outside of the monitor 3 to provide protection for the monitor 3 and prevent damage from sun exposure, rain, and external impact. Four support rods 601 are fixedly installed at the lower end of the protective cover 6 and extend downward to support the protective cover 6 at the upper end of the mounting rod 1. The mounting groove is opened on the upper surface of the mounting rod 1 to accommodate the lower end of the support rod 601. The fixing structure 7 is located between two adjacent support rods 601 to lock the support rod 601 inside the mounting groove.

[0036] The fixing structure 7 includes a mounting block 701. The upper surface of the mounting block 701 has a groove. Two sliding plates 702 are slidably connected inside the groove. A spring 703 is fixedly installed between the two sliding plates 702. A fixing block 704 is installed at the other end of each of the two sliding plates 702.

[0037] The mounting block 701 is disposed between two adjacent support rods 601 and embedded in the upper surface of the mounting rod 1, providing mounting space for the slide plate 702 and the spring 703. The two slide plates 702 are slidably mounted inside the groove and move back and forth in the horizontal direction. The spring 703 is disposed between the two slide plates 702, and its elastic force pushes the two slide plates 702 to move away from each other. The fixing block 704 is fixedly mounted on the end of the slide plate 702 away from the spring 703 and moves synchronously with the slide plate 702, extending out of the mounting block 701 and inserting into the fixing groove on the outside of the support rod 601.

[0038] A cover plate 705 is installed on the upper surface of the mounting block 701. An opening is provided in the middle of the cover plate 705. Two levers 706 are slidably connected inside the opening. Both levers 706 are fixedly installed on the upper surface of the corresponding slide plate 702. A placement groove is also provided on the upper surface of the mounting rod 1. The mounting block 701 is installed in the placement groove. A fixing groove is provided on one side of the support rod 601. One end of the fixing block 704 passes through the mounting block 701 and the mounting rod 1 in sequence and is installed in the fixing groove.

[0039] The cover plate 705 is fixedly installed on the upper surface of the mounting block 701 to close the upper opening of the groove and limit the sliding plate 702. The lever 706 passes through the opening and extends upward. The lower end of the lever 706 is fixedly connected to the upper surface of the sliding plate 702, so that the operator can hold it and apply external force to drive the two sliding plates 702 to move towards each other against the elastic force of the spring 703, so that the fixing block 704 is removed from the fixing groove. The placement groove is opened on the upper surface of the mounting rod 1 to accommodate the mounting block 701. The fixing groove is opened on the outside of the support rod 601 to accommodate the end of the fixing block 704.

[0040] A sealing block 707 is also installed inside the opening, and the sealing block 707 is located between two levers 706;

[0041] The sealing block 707 is located inside the opening and between the two levers 706. It is used to close the opening when the protective cover 6 is in normal use to prevent external debris from entering the groove. When the protective cover 6 needs to be disassembled, the sealing block 707 is removed first, and then the two levers 706 can be moved.

[0042] In use, first, fix the mounting rod 1 to the monitoring point on the mountain slope through the base 102. Then, adjust the pitch angle of the monitor 3 according to the terrain undulation and vegetation obstruction. Hold the handle 206 and rotate the handle 206. The handle 206 drives the worm gear 205 to rotate. The worm gear 205 drives the connecting seat 202 to swing around the horizontal axis relative to the mounting seat 201 through the worm wheel 203. The connecting seat 202 drives the monitor 3 to swing synchronously. At the same time, the connecting rod 207 slides along the slide groove. The pointer 210 rotates with the connecting seat 202 and points to the corresponding position of the scale line 209. When the monitor 3 is rotated to the optimal monitoring position, stop rotating the handle 206, tighten the nut 208 at the lower end of the connecting rod 207, and lock the connecting seat 202 and the mounting seat 201 to complete the angle adjustment of the monitor 3.

[0043] After the angle adjustment is completed, install the protective cover 6 on the upper end of the mounting rod 1. Hold the two levers 706 and move them towards each other. The two levers 706 drive the two sliding plates 702 to move towards each other against the elastic force of the spring 703. The sliding plates 702 drive the fixing block 704 to move closer to the spring 703, causing the fixing block 704 to retract into the mounting block 701. Then, place the mounting block 701 into the placement slot and insert the four support rods 601 downwards, aligning them with the four mounting slots on the upper surface of the mounting rod 1. The lower end of 1 enters the mounting groove. The fixing groove on the outside of the support rod 601 corresponds to the position of the fixing block 704. Then, the force on the push block 706 is released. The spring 703 pushes the two slide plates 702 to move away from each other. The slide plates 702 drive the fixing block 704 to extend out of the mounting block 701. The fixing block 704 passes through the mounting rod 1 in sequence and is inserted into the fixing groove on the outside of the support rod 601, completing the locking and fixing of the protective cover 6 and the mounting rod 1. Then, the sealing block 707 is installed inside the opening to close the opening.

[0044] When it is necessary to disassemble the protective cover 6, first take out the sealing block 707, then hold the two levers 706 and move them in opposite directions. The two levers 706 drive the two sliding plates 702 to move in opposite directions against the elastic force of the spring 703. The sliding plates 702 drive the fixing block 704 to exit from the fixing groove, releasing the lock on the support rod 601. Then, the protective cover 6 can be lifted upwards, and the support rod 601 can be pulled out from the mounting groove to complete the disassembly.

[0045] After the angle adjustment of the monitor 3 and the installation of the protective cover 6 are completed, the monitor 3 starts to work, collects slope displacement data in real time and transmits it to the control cabinet 4. The control cabinet 4 compares the received displacement data with the preset threshold. When the displacement data exceeds the limit, the control cabinet 4 triggers the audible and visual alarm 5 to issue an audible and visual alarm signal.

[0046] The stepless adjustment of the pitch angle of the monitor 3 is achieved through the meshing of the worm gear 205 and the worm wheel 203. This meshing has a self-locking characteristic; that is, the worm gear 205 can drive the worm wheel 203 to rotate, but the worm wheel 203 cannot drive the worm gear 205 to rotate in the opposite direction. After the angle adjustment is completed, the pitch angle of the monitor 3 remains stable, preventing angle deviation due to its own weight or wind force. The interaction between the pointer 210 and the scale 209 facilitates the operator in reading and recording the current angle value during the adjustment process. With high adjustment precision, the threaded engagement between the nut 208 and the connecting rod 207 further locks the connecting seat 202 after angle adjustment, preventing the monitor 3 from shifting due to vibration during long-term use. The fixing structure 7 achieves quick installation and removal of the protective cover 6 through the insertion and engagement of the fixing block 704 and the fixing groove, which can be completed without the aid of tools. The sealing block 707 seals the opening under normal use of the protective cover 6 to prevent external debris from entering the groove. When it is necessary to remove the protective cover 6, the sealing block 707 can be removed to move the lever 706.
