[0002] The slope monitoring alarm device is a device used to monitor the stability of the slope in real time and issue an alarm in time. Slope geological disasters (such as landslides, collapses, etc.) pose a serious threat to the safety of people's lives and property. Therefore, it is necessary to install a monitoring alarm device to timely discover and warn of potential risks. The existing process of installing a slope monitoring alarm device is usually as follows: first, select a suitable installation location on the slope to cast a base deep underground, then install the monitoring alarm device on the base and adjust the inclination angle of the video monitoring module of the monitoring alarm device so that the shooting range of the video monitoring module fully covers the slope surface. If there is rockfall or landslide on the slope, the monitoring alarm device will issue an alarm.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0022] Example 1: During the installation of the existing monitoring and alarm device, if the surface of the base is uneven, the monitoring and alarm device will be tilted at a certain angle when it is installed on the base, making it impossible to quickly determine the tilt angle of the video shooting module in the monitoring and alarm device. It is easy for the monitoring range of the video shooting module to fail to fully cover the slope surface, making it impossible to monitor some areas of the slope surface, increasing the risk of potential slope landslides and posing a safety hazard to surrounding residents and facilities.

[0023] A monitoring and alarm device for preventing and controlling geological disasters on slopes, please refer to the attached Figure 1 -Attached Figure 8 As shown, it includes: a mounting shell 1, on which a rotating frame 2 is rotatably connected, and the rotating frame 2 is limitedly and slidably connected to a connecting column 3, and a variety of modules are arranged on the connecting column 3 for monitoring a variety of data of the slope; two limit blocks 4, which are slidably connected in the connecting column 3, and a spring is fixedly connected between the limit block 4 and the connecting column 3, and the rotating frame 2 is provided with two blind holes, and the limit block 4 is limitedly matched with the blind holes of the rotating frame 2; a knob 5, which is rotatably connected to the rotating frame 2, and a damping is arranged between the knob 5 and the rotating frame 2, and the knob 5 is fixedly connected to a fixed block 6, and the rotating frame 2 is rotatably connected to a weight block 7, and the fixed block 6 is provided with a pressure sensing sheet that is pressed and matched with the weight block 7, and is used to set the inclination angle of the connecting column 3; an angle locking mechanism, which is arranged on the rotating frame 2, and is used to make the mounting shell 1 and the rotating frame 2 relatively fixed. Fixed; a protection mechanism is arranged in the mounting shell 1, and is used to protect the module on the connecting column 3. The contact surfaces of the mounting shell 1 and the rotating frame 2 are both spherical surfaces, which are used to ensure that the mounting shell 1 is always in a closed state during the rotation of the rotating frame 2. The angle locking mechanism includes: a hydraulic cylinder 201, which is rotatably connected to the mounting shell 1, and the hydraulic cylinder 201 is connected to a liquid guide tube 202. A liquid storage cylinder 203 is fixedly connected in the mounting shell 1, and the liquid storage cylinder 203 is connected to the liquid guide tube 202. A sliding plate 204 is sealed and slidably connected at the connection between the liquid guide tube 202 and the liquid storage cylinder 203. The sliding plate 204 is provided with a through hole that is connected to the liquid guide tube 202, and is used to relatively fix the mounting shell 1 and the rotating frame 2; an electric push rod 205, which is fixed in the mounting shell 1, and the telescopic end of the electric push rod 205 is fixedly connected to the sliding plate 204.

[0024] In the above scheme, the problem that the tilt angle of the video shooting module of the monitoring alarm device installed on the base cannot be accurately adjusted when the base surface is tilted is solved. The rotating frame 2 is located at the upper part of the mounting shell 1. The mounting shell 1 is provided with a solar panel and a control box. The modules on the connecting column 3, the pressure sensing sheet on the fixed block 6 and the angle locking mechanism are electrically connected to the control box. The modules on the connecting column 3 include: a sensor module, a communication module, an alarm module and a video monitoring module, etc. The sensor module is installed with different types of sensors according to monitoring requirements, such as a displacement sensor, a stress strain sensor, a hydrological sensor, etc. The center of the spherical surface of the rotating frame 2 is located on its rotation axis, so that the mounting shell 1 remains sealed during the rotation of the rotating frame 2 to prevent external impurities from entering the mounting shell 1 and corroding the parts in the device. A notch is provided on the mounting shell 1 at the right side of the rotating frame 2. The width of the notch is equal to the width of the connecting column 3, so that the connecting column 3 can smoothly enter the mounting shell as the rotating frame 2 rotates. 1, due to the damping between the knob 5 and the rotating frame 2, the knob 5 can rotate relative to the rotating frame 2 only when it is manually rotated, which is convenient for setting the inclination angle of the connecting column 3 (the set inclination angle is calculated in advance by the operator according to the inclination angle and area of ​​the slope, combined with the position of the monitoring alarm device installed at the lower part of the slope, so that the device can fully monitor the surface of the slope after installation), the angle between the fixed block 6 and the weight block 7 is equal to the inclination angle of the video monitoring module in the device, initially, the liquid guide tube 202 and the liquid storage cylinder 203 are connected through the through hole of the sliding plate 204, the telescopic end of the hydraulic cylinder 201 can be freely extended and retracted, and the rotating frame 2 can be locked at any time during the rotation process through the communication cooperation between the through hole of the sliding plate 204 and the liquid guide tube 202, and the accurate positioning of the inclination angle of the video monitoring module is completed through the cooperation of the fixed block 6 and the weight block 7, so as to ensure the comprehensiveness of the slope surface monitoring during the use of the device and reduce the possibility of potential safety hazards.

[0025] Workflow: First, the operator inserts the connecting column 3 into the rotating frame 2, the inclined surface of the limit block 4 squeezes the rotating frame 2, the limit block 4 moves into the connecting column 3 and compresses the connected spring, when the limit block 4 is aligned with the blind hole of the rotating frame 2, the limit block 4 moves and inserts into the blind hole of the rotating frame 2 under the elastic force of the connected spring, the connecting column 3 is fixed on the rotating frame 2, and the auxiliary fixing assembly assists the connecting column 3 to be fixed in the rotating frame 2, then the operator turns the knob 5 to a certain angle to clamp the fixing block 6 and the weight block 7. The angle is the set angle, the knob 5 drives the fixed block 6 to rotate synchronously, the weight block 7 is always in a vertical state under the action of gravity, and then the operator swings the connecting column 3 to the right, the connecting column 3 drives the rotating frame 2 to rotate clockwise (from front to back), the rotating frame 2 drives the fixed block 6 to rotate synchronously through the knob 5, the telescopic end of the hydraulic cylinder 201 is pulled out, the hydraulic cylinder 201 rotates adaptively, and the hydraulic oil in the liquid storage cylinder 203 enters the hydraulic cylinder 201 through the through hole of the sliding plate 204 and the liquid guide tube 202.

[0026] During the rotation of the rotating frame 2, if the pressure sensing piece on the fixed block 6 contacts the weight block 7, the inclination angle of the video monitoring module on the connecting column 3 is the set angle, and the pressure sensing piece feeds back a signal to the control box, which starts the electric push rod 205, and the telescopic end of the electric push rod 205 extends and drives the sliding plate 204 to move forward. The through hole on the sliding plate 204 is misaligned with the liquid guide tube 202, and the liquid guide tube 202 is blocked. The telescopic end of the hydraulic cylinder 201 stops moving, and the mounting shell 1 and the rotating frame 2 are relatively locked. At this point, all installation operations of the device are completed. The device monitors the slope, and performs emergency alarm processing when rockfall or landslide occurs on the slope, alerts nearby personnel, and ensures the life safety of nearby personnel. After the device is used for a long time, if the module on the connecting column 3 fails, the operator manually moves the two limit blocks 4 closer to each other, and the limit blocks 4 compress the connected springs and move out of the blind hole of the rotating frame 2. The relatively fixed contact between the rotating frame 2 and the connecting column 3 can directly remove the connecting column 3 for maintenance.

[0027] During the use of the device, if the slope has a landslide, the operator releases the connection between the telescopic end of the hydraulic cylinder 201 and the rotating frame 2 through the protection mechanism. At the same time, the control box controls the rotating frame 2 to rotate clockwise (from front to back) through the protection mechanism. The rotating frame 2 drives the connecting column 3 into the installation shell 1 for storage protection to prevent the landslide from directly hitting the module on the connecting column 3, thereby ensuring the security of the data in the module on the connecting column 3 and facilitating the subsequent analysis by the operator based on the monitoring data.

[0028] Please refer to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 5 -Attached Figure 7 and attached Fig. 9As shown, the protection mechanism includes: a motor 301, which is fixed to the mounting shell 1, the output shaft of the motor 301 is rotatably connected to the mounting shell 1, the upper part of the mounting shell 1 is rotatably connected to a rotating ring 302, and the output shaft of the motor 301 and the rotating ring 302 are transmitted through gears and gear rings; a connecting bent rod 303, which is slidably connected to the rotating frame 2, the telescopic end of the hydraulic cylinder 201 is slidably and rotatably connected to the connecting bent rod 303, a spring is fixed between the connecting bent rod 303 and the rotating frame 2, and the rotating ring 302 is fixed to a fixed rod 304, which is extruded and matched with the connecting bent rod 303 to release the connection between the telescopic end of the hydraulic cylinder 201 and the rotating frame 2; a closing component, which is arranged in the rotating frame 2 and is used to control the connection state between the space inside the mounting shell 1 and the outside world; an auxiliary fixing component , arranged on the rotating frame 2, used to stably fix the connecting column 3 in the rotating frame 2 and enable it to be quickly replaced, the closing component includes: a fixed plate 401, fixedly connected to the rotating frame 2, used to protect the connecting column 3 from being squeezed; two sliding baffles 402, slidably connected to the mounting shell 1, the fixed plate 401 and the sliding baffle 402 are squeezed and matched, a spring is fixed between the sliding baffle 402 and the mounting shell 1, the sliding baffle 402 is used to close the space in the mounting shell 1, the width of the fixed plate 401 gradually increases from bottom to top, the maximum width of the fixed plate 401 is greater than the maximum width of the upper part of the connecting column 3, used to prevent the connecting column 3 from being squeezed by the sliding baffle 402, the fixed plate 401 is provided with two inclined surfaces, the inclined surfaces of the fixed plate 401 are squeezed and matched with the sliding baffle 402.

[0029] In the above scheme, it is intended to solve the problem that the monitoring alarm device is easily damaged when a landslide occurs on the slope, which is not conducive to the operator's recovery of the monitoring data in the monitoring alarm device. The output shaft of the motor 301 only drives the rotating ring 302 to rotate clockwise (from front to back) through the gear and the gear ring. The fixed rod 304 is an inclined rod. The inclination direction of the fixed rod 304 is upward from back to front. After the fixed rod 304 pushes the connecting bent rod 303 into the rotating frame 2 to the limit, the front end of the connecting bent rod 303 is still located outside the spherical surface of the rotating frame 2 (see Figure 2). Fig. 9The fixing rod 304 and the connecting bent rod 303 are in a state where they are not squeezed against each other. The front part of the connecting bent rod 303 is located outside the spherical surface of the rotating frame 2. The fixing rod 304 pushes the connecting bent rod 303 into the rotating frame 2 during the rotation of the rotating ring 302. The fixing rod 304 is always in contact with the rotating frame 2 during the rotation of the rotating ring 302. The horizontal cross section of the fixing plate 401 is an isosceles triangle. The cross section area of ​​the fixing plate 401 gradually increases from bottom to top. The moving track of the rightmost edge line of the fixing plate 401 is located on the vertical plane where the contact surfaces of the two sliding baffles 402 are located. The fixing plate 401 is located on the right part of the connecting column 3. The sliding baffles 402 are located on the right side of the connecting column 3. The movable baffle plate 402 is located at the right part of the mounting shell 1, and the inclined surface of the fixed plate 401 squeezes the two sliding baffle plates 402 to make the two move away from each other, thereby ensuring that the connecting column 3 smoothly enters the mounting shell 1 for storage. Initially, the plane where the upper end of the fixed plate 401 is located is higher than the plane where the upper end of the connecting column 3 is located. The connecting column 3 is driven to rotate by the fixed rod 304 and the connecting bent rod 303. Combined with the movement of the sliding baffle plate 402, the connecting column 3 enters the mounting shell 1 for storage protection, preventing the landslide of the slope from directly impacting the connecting column 3, and effectively protecting the monitoring data of the device, which is convenient for the subsequent recovery and analysis of the monitoring data.

[0030] Workflow: When the slope has landslide or rockfall, if the device detects that the connecting column 3 is about to be impacted, the monitoring data in the module on the connecting column 3 may be lost, the control box starts the motor 301, and the output shaft of the motor 301 drives the rotating ring 302 to rotate clockwise (from front to back) through the gear and the gear ring, and the rotating ring 302 drives the fixed rod 304 to move synchronously, and the fixed rod 304 squeezes and pushes the connecting bent rod 303 to move backward, and the connecting bent rod 303 compresses the connected spring, and the connecting bent rod The connection between 303 and the telescopic end of the hydraulic cylinder 201 is released. When the connecting bent rod 303 moves backward to the limit, the rotating ring 302 drives the rotating frame 2 to rotate synchronously through the fixed rod 304 and the connecting bent rod 303, and the rotating frame 2 drives the connecting column 3 to move synchronously. The right edge line of the fixed plate 401 is inserted between the two sliding baffles 402. The inclined surface of the fixed plate 401 pushes the sliding baffle 402 to move. The sliding baffle 402 compresses the connected spring, and the two sliding baffles 402 move away from each other, and the space inside the installation shell 1 is opened.

[0031] As the rotating frame 2 rotates, the connecting column 3 gradually enters the mounting shell 1, and then the sliding baffle 402 loses its extrusion and moves back to its original position under the elastic force of the connected spring, and the space inside the mounting shell 1 is re-closed. When the connecting column 3 swings to a vertical state, the control box turns off the motor 301, and the connecting column 3 is isolated and protected in the mounting shell 1 to prevent the soil and stones sliding down the slope from directly hitting the connecting column 3, thereby protecting the security of the monitoring data of the device and facilitating the operator to conduct disaster analysis based on the data.

[0032] Please refer to the attached Figure 3 and attached Figure 4 As shown, the auxiliary fixing component includes: a rotating circular plate 501, which is rotatably connected to the rotating frame 2, and a support plate 502 is slidably connected in the rotating frame 2, and the support plate 502 is pressed and matched with the connecting column 3. A spring is fixedly connected between the rotating circular plate 501 and the support plate 502, which is used to fix the relative position of the rotating frame 2 and the connecting column 3; two sliding blocks 503 are respectively slidably connected to the corresponding blind holes of the rotating frame 2, and the sliding blocks 503 are pressed and matched with the limit blocks 4. The auxiliary fixing component also includes: a stopper 601, which is slidably connected to the mounting shell 1, and a spring is fixedly connected between the stopper 601 and the mounting shell 1. The stopper 601 is limited and matched with the blind hole on the rotating frame 2, which is used to keep the rotating frame 2 fixed when the connecting column 3 is installed.

[0033] In the above scheme, the purpose is to ensure the stability of the state of the connecting column 3 during the use of the device, to prevent the connecting column 3 from shaking in strong winds or other situations, and to affect the stability of the video monitoring module shooting picture. The side of the sliding block 503 is an arc surface and coincides with the spherical surface of the side wall of the rotating frame 2, so as to ensure that the rotating frame 2 is not hindered during the rotation of the mounting shell 1. The block 601 is provided with an inclined surface inclined to the left from top to bottom, and cooperates with the blind hole on the rotating frame 2 so that the rotating frame 2 can only rotate clockwise (from front to back). The elastic coefficient of the spring connected to the block 601 is less than the elastic coefficient of the spring connected to the limit block 4. After the limit block 4 enters the blind hole of the rotating frame 2, the sliding block 503 pushes the block 601 out of the blind hole of the rotating frame 2, and the block 601 releases the limit on the rotating frame 2. The rotating frame 2 is limited by the block 601, and the connecting column 3 is pushed in combination with the support plate 502 to ensure the stability of the connecting column 3 in the fixed state in the rotating frame 2.

[0034] Working process: before the operator prepares to insert the connecting column 3 into the rotating frame 2, the stopper 601 is located in the blind hole of the rotating frame 2, the rotating frame 2 is limited, and the rotating circular plate 501 is located at the lower part of the rotating frame 2. Then the operator inserts the connecting column 3 into the rotating frame 2. The stopper 601 ensures that the position of the rotating frame 2 remains stable when the connecting column 3 is installed, so that the connecting column 3 can be accurately installed. The connecting column 3 squeezes and pushes the support plate 502 to move downward, and the support plate 502 compresses the connected spring. When the limit block 4 enters the blind hole of the rotating frame 2, the support plate 502 is limited by the elastic force of the connected spring and the limit block 4, so that the relative position of the rotating frame 2 and the connecting column 3 is stably fixed. Then, the above-mentioned operation of relatively fixing the installation shell 1 and the rotating frame 2 is repeated to ensure the stability of the state of the connecting column 3 after installation, and reduce the interference of strong wind weather on the monitoring state of the device.

[0035] Example 2: Based on Example 1, please refer to the attached Figure 1 -Attached Figure 4 and attached Fig.10As shown, it also includes: a quick disassembly mechanism, which is arranged on the rotating circular plate 501 and is used to quickly release the connection state between the rotating frame 2 and the connecting column 3. The quick disassembly mechanism includes: a rotating pull rod 701, which is fixed to the rotating circular plate 501, and the rotating pull rod 701 passes through the rotating circular plate 501 and the support plate 502. The lower part of the connecting column 3 is provided with a blind hole, and the rotating pull rod 701 is slidably connected to the support plate 502; a limiting rod 702, which is fixed to the rotating pull rod 701, and the limiting rod 702 is limitedly matched with the blind hole on the connecting column 3, so that the rotating pull rod 701 and the connecting column 3 are connected. The lower part of the blind hole on the connecting column 3 is provided with four protrusions, and the limiting rod 702 is pressed and matched with the protrusions in the blind hole of the connecting column 3, so that the rotating pull rod 701 drives the connecting column 3 to move through the limiting rod 702, and the limiting block 4 is provided with an inclined surface, and the spacing between the inclined surfaces of the two limiting blocks 4 gradually decreases from top to bottom, so as to release the connection between the rotating frame 2 and the connecting column 3.

[0036] In the above scheme, it is intended to enable the connection column 3 to be quickly installed, replaced and disassembled, and reduce the convenience of operators to recover monitoring data. The protrusions in the blind hole of the connection column 3 are evenly distributed in the circumferential direction, and two mirror-distributed grooves are arranged on the rotating circular plate 501, so that the rotating circular plate 501 can lose the connection with the rotating frame 2 after rotating to a set angle. The area of ​​the projection of the connection column 3 on the horizontal plane is smaller than the area of ​​the middle space of the rotating frame 2, so that the connection column 3 can be moved out of the device through the rotating frame 2. When the connection column 3 is installed, the uppermost limit rod 702 is set The end is fitted with the upper side surface of the blind hole of the connecting column 3, the lower side surface of the limiting rod 702 coincides with the plane where the upper side surface of the protrusion in the blind hole of the connecting column 3 is located, the lowermost part of the rotating rod 701 is a handle, and the lowermost end of the rotating rod 701 is located within the spherical range where the side wall of the rotating frame 2 is located, so that the rotating rod 701 does not contact with any parts during the rotation of the rotating frame 2. By rotating the rotating rod 701, the connection state between the rotating circular plate 501 and the rotating frame 2 is changed, so as to achieve the purpose of quickly taking away the monitoring data of the device, and ensure the rapidity of data recovery when the device is used.

[0037] Working process: when the connecting column 3 is inserted into the rotating frame 2, the limiting rod 702 is inserted into the blind hole of the connecting column 3, and the limiting rod 702 does not contact the protrusion in the blind hole of the connecting column 3. When a landslide disaster occurs, the rotating circular plate 501 rotates to the uppermost side of the rotating frame 2, and the connecting column 3 is stored and protected in the mounting shell 1. If the operator needs to recover the monitoring data of the device, the operator only needs to dig out the uppermost end of the device. The operator holds the rotating pull rod 701 and rotates it. The rotating pull rod 701 drives the rotating circular plate 501 to rotate synchronously. When the groove on the rotating circular plate 501 forms a set angle with the rotating frame 2, the rotating circular plate 501 is connected to the rotating frame 2. The relationship is released, the limit rod 702 cooperates with the protrusion in the blind hole of the connecting column 3, the operator lifts the rotating pull rod 701, and the rotating pull rod 701 drives the connecting column 3 to move synchronously through the limit rod 702. The limit block 4 is inclined and squeezes the edge of the blind hole of the rotating frame 2. The limit block 4 moves into the connecting column 3 and compresses the connected spring. The connecting column 3 moves out of the device through the middle of the rotating frame 2. The limit block 4 moves and resets under the elastic force of the connected spring. The recovery of the monitoring data in the device is now completed. If the device is continued to be used in the future, all parts will be restored to their initial positions, and the above-mentioned installation and angle adjustment operations of the connecting column 3 can be repeated, and the device can continue to be used to monitor the slope.
