Description

Technical Field

[0001] The invention relates to the technical field of rockfall protection for dangerous rocks on a geotechnical engineering slope, and in particular to a rockfall protection system. Background Art

[0002] In slope protection projects, rockfall is a common natural disaster that not only poses a serious threat to the roads, buildings and pedestrians below, but may also cause significant economic losses. Existing slope rockfall protection buffer equipment is usually equipped with a buffer structure to ensure that the equipment can effectively absorb energy and disperse pressure when impacted by rockfall. When rockfall falls from above and hits the equipment, its weight will be applied to the bottom of the equipment, and the pre-set stable structure can withstand this additional pressure, thereby preventing the equipment from being displaced or overturned due to external forces.

[0045] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0046] like Figure 1 , Figure 2 , Figures 4 to 6 As shown, the present invention provides a rockfall protection system, including a main structure 1, a buffer device 2, a fixing device 3 and an early warning device 4, wherein the main structure 1 has a first side surface 11 and a second side surface 12 arranged opposite to each other, and a rockfall path 13 extending from the first side surface 11 to the second side surface 12; the buffer device 2 is slidably installed on the main structure 1, and the buffer device 2 is arranged on the rockfall path 13, aiming to guide the rockfall to move in a predetermined direction to ensure that it can roll until it contacts the buffer device 2; the main structure 1 is installed on the plane to be installed through the fixing device 3, ensuring that the entire protection system does not shift or overturn when facing the impact of rockfall, thereby maintaining its protection effectiveness; it can be understood that the plane to be installed can be a slope or a rock edge to be protected; the early warning device 4 includes a storage The electrolyte liquid comprises a liquid storage component 41, a telescopic component 42, a conductive component 43 and an early warning component 44, wherein the electrolyte liquid acts as a conductive medium in the system, the liquid storage component 41, the conductive component 43 and the early warning component 44 are installed on the second side 12, the conductive component 43 is installed on the liquid storage component 41, and the conductive component 43 is partially located in the liquid storage component 41, the input end of the conductive component 43 is externally connected to a power supply, and the output end is electrically connected to the early warning component 44, the telescopic component 42 is slidably installed on the main structure 1, and one side of the telescopic component 42 is abutted against the buffer device 2, and the other side is connected to the liquid storage component 41, so that when the telescopic component 42 is compressed by the pressure of the buffer device 2, the electrolyte liquid in the liquid storage component 41 is pumped to contact the conductive component 43 located in the liquid storage component 41.

[0047] Based on the above structure, the rockfall protection system is installed at a location such as a slope through a fixing device 3, and the first side surface 11 is arranged toward the slope. When the rockfall slides down the path, it will first hit the buffer device 2, which absorbs and disperses the impact energy brought by the rockfall, reducing the harm to the structure or personnel below. As the buffer device 2 is subjected to pressure, it slides backward and applies pressure to the telescopic component 42. As the telescopic component 42 is compressed, the telescopic component 42 pumps the electrolyte liquid in the liquid storage component 41 to the conductive component 43 located in the liquid storage component 41, so that the conductive component 43 forms a circuit closure through the electrolyte; at this time, the early warning component 44 receives the electrical signal from the conductive component 43, triggering an alarm mechanism, such as an audible and visual alarm, sending a remote notification, etc. This embodiment solves the problem that traditional slope rockfall protection equipment lacks an effective early warning method. Once a rockfall activity is detected, the system can respond immediately and provide a timely warning, so that relevant personnel can take measures quickly to avoid or reduce possible damage.

[0048] Furthermore, the main structure includes a structural base plate 14 and two groups of structural side panels 15 fixedly connected to the top of the structural base plate 14. The two groups of structural side panels 15 are symmetrically distributed on the top of the structural base plate 14. The top of the structural base plate 14 is fixedly connected with a second side surface 12. The two sides of the second side surface 12 are respectively connected to the structural side panels 15 and are vertically arranged with the structural side panels 15 to enclose a stone rolling path 13 with an opening at one end. A fixing device 3 is arranged on the outer side of the structural base plate 14. The buffer device 2 is arranged on the top of the structural base plate 14. The structural base plate 14 provides support for the buffer device 2 above it. The two groups of structural side panels 15 can limit falling rocks and the second side surface 12 can provide support for the subsequent installation of a monitoring device 6 of the device.

[0049] It can be understood that the structural base plate 14 of this embodiment has a first side surface 11 on a side facing away from the second side surface 12 .

[0050] like Figure 7 and Figure 8 As shown, the liquid storage component 41 includes a liquid storage tank 411, a liquid outlet pipe 412 and a liquid storage cylinder 413. The liquid storage tank 411 serves as a container for storing electrolyte liquid. It is connected to the telescopic component 42, and its output end is connected to the liquid storage cylinder 413 through the liquid outlet pipe 412. The liquid storage cylinder 413 is used to receive the electrolyte liquid transported from the liquid storage tank 411 through the liquid outlet pipe 412, so that the electrolyte liquid in the liquid storage tank 411 flows into the liquid storage cylinder 413 through the liquid outlet pipe 412. This mechanism is triggered by a change in pressure. When the telescopic component 42 is compressed, the telescopic component 42 pumps the electrolyte liquid in the liquid storage tank 411 to the liquid storage cylinder 413. A sealing outer ring is installed on the outer side of the bottom end of the liquid outlet pipe 412 to improve the sealing of the connection between the liquid outlet pipe 412 and the liquid storage tank 411.

[0051] The conducting component 43 includes a power input conductive rod 431 and a power output conductive rod 432. The power input conductive rod 431 and the power output conductive rod 432 are relatively arranged at two ends of the liquid storage cylinder 413, and the power input conductive rod 431 is arranged to pass through the liquid storage cylinder 413, and its end outside the liquid storage cylinder 413 is connected to a power input line 435 to introduce power into the system. The power output conductive rod 432 is arranged to pass through the liquid storage cylinder 413, and its end outside the liquid storage cylinder 413 is electrically connected to the early warning component 44, which is used to transmit an electrical signal to the early warning component 44 to trigger an alarm.

[0052] The conduction component 43 of the present embodiment is intended to provide an electrical path that can be closed by the electrolyte liquid. Under normal conditions, there is no direct contact between the power input conductive rod 431 and the power output conductive rod 432, so the circuit is in an open state. However, after the electrolyte liquid in the liquid storage tank 411 is pumped into the liquid storage cylinder 413, since the electrolyte liquid has conductivity, it can be used as a bridge to connect the power input conductive rod 431 and the power output conductive rod 432, thereby forming a complete circuit. Once the circuit is closed, the current will flow in from the power input conductive rod 431, pass through the electrolyte liquid in the liquid storage cylinder 413, and then flow out from the power output conductive rod 432, and finally reach the early warning component 44, triggering the alarm, realizing the automatic early warning function.

[0053] The telescopic assembly 42 of this embodiment includes a telescopic sleeve 421, a contact plate 422 and a guide slider 423. The telescopic sleeve 421 is installed on one side of the liquid storage tank 411, and the contact plate 422 is provided on one side of the telescopic sleeve 421. Two groups of guide sliders 423 are provided at the bottom of the contact plate 422. The two groups of guide sliders 423 are symmetrically distributed at the bottom of the contact plate 422. Two groups of guide slides 16 (such as Figure 4 As shown in FIG. 1 , two sets of guide slots 16 are symmetrically distributed on the top of the structural bottom plate 14. The liquid storage tank 411 is in contact with the buffer plate 21 through the telescopic sleeve 421 and the contact plate 422. When a rockfall occurs, the liquid storage tank 411 can move backward with the buffer plate 21 to be compressed, thereby reducing the volume in the liquid storage tank 411 and increasing the pressure. The electrolyte is discharged from the liquid outlet pipe 412 through the pressure; wherein the two sets of guide sliders 423 can slide along the two sets of guide slots 16, thereby ensuring stability during telescopic movement.

[0054] It should be noted that, in this embodiment, a power input conductive rod 431 is provided with a conductive terminal at one end outside the liquid storage cylinder 413, a wiring copper nose 433 is provided at one end of the conductive terminal, a tightening bolt 434 is threadedly connected to the outer locking end of the wiring copper nose 433, a power input line 435 is installed on one side of the wiring copper nose 433, a sealing jacket 436 is provided on the outer side of the conductive terminal, and an early warning component 44 is installed on one side of the second side 12, as shown in FIG. Figure 6As shown, the early warning component 44 includes an early warning light box 441, a sealed back cover 442, a light box controller 443, a light box terminal 444 and an early warning unit wireless signal transmitter 445. A sealed back cover 442 is provided on one side of the early warning light box 441, a light box controller 443 is installed inside the sealed back cover 442, two groups of light box terminals 444 are provided on one side of the light box controller 443, the two groups of light box terminals 444 are symmetrically distributed on one side of the light box controller 443, and the early warning unit wireless signal transmitter 445 is plugged into the other side of the light box controller 443.

[0055] The power input conductive rod 431 and the power output conductive rod 432 are both made of conductive materials, and are connected to the power input line 435 and the warning component 44 through the use of the wiring copper nose 433 and the tightening bolt 434, wherein the warning component 44 can be connected to the power output conductive rod 432 through the power output line, and when the telescopic sleeve 421 is compressed, the electrolyte can be injected into the liquid storage cylinder 413, so that the electrolyte can fill the liquid storage cylinder 413 and connect the power input conductive rod 431 and the power output conductive rod 432 through the conductivity of the electrolyte, further connecting the power input line 435 and the power output line, and energizing the light box controller 443, so that the lamp body in the warning light box 441 emits light to remind the staff and surrounding personnel; wherein the two groups of light box terminal 444 are the wiring units of the warning light box 441; wherein the use of the warning unit wireless signal transmitter 445 can transmit the light emission of the warning light box 441 to the remote device to remind the staff.

[0056] like Figure 1 , Figure 3 and Figure 4As shown, the main structure 1 has a first slide groove 17, and the buffer device 2 includes a buffer plate 21, an anti-dropping top plate 22, a first slide bar 23 and a plurality of buffer components 24. The buffer plate 21 is arranged on the top of the structural bottom plate 14, and includes a third side surface 211 facing the rolling stone path 13 and a fourth side surface 212 away from the rolling stone path 13. The third side surface 211 of the buffer plate 21 is arc-shaped, so that the falling stone can roll along the arc-shaped surface and provide a larger surface area to disperse the pressure when in contact, which helps to reduce the local impact force on the buffer plate 21, thereby improving its durability. The fourth side surface 212 is connected to the second side surface 12 through the buffer component 24, and the fourth side surface 212 is connected to the telescopic component 42 Abutment, when the buffer plate 21 is impacted and slides backward, it will compress the telescopic component 42, thereby triggering the early warning component 44; multiple groups of buffer components 24 are arranged at intervals along the first direction, aiming to absorb and disperse the impact energy caused by falling rocks, while maintaining the stability and effectiveness of the system, the buffer plate 21 is slidably installed on the first slide groove 17 through the first slide bar 23, the first slide groove 17 serves as a guide track on the main structure 1, and is used to guide the buffer device 2 to slide thereon, ensuring that the buffer device 2 can move along a predetermined path when impacted by falling rocks, and the anti-detachment top plate 22 is installed on the top of the buffer plate 21 to prevent falling rocks from accidentally escaping from the buffer plate 21, thereby increasing the safety of the entire system.

[0057] The first slide bar 23 of this embodiment is a T-shaped structure, and two groups of first slide bars 23 of the T-shaped structure are symmetrically distributed at the bottom of the buffer plate 21, and the two groups of first slide grooves 17 opened on the top of the structural bottom plate 14 are also symmetrically distributed on the top of the structural bottom plate 14. It should be noted that the first direction of this embodiment is the length direction of the second side surface 12.

[0058] like Fig. 9As shown, the buffer assembly 24 includes a spring sleeve 241, a movable spring plate 242, a plurality of damping shock absorbers 243 and a buffer spring 244. The spring sleeve 241 is connected to the movable spring plate 242 through the damping shock absorber 243. The spring sleeve 241 is installed on the second side 12. The spring sleeve 241 serves as a fixed end to provide a stable foundation for the entire buffer assembly 24. The movable spring plate 242 is installed on the fourth side 212. It serves as a movable end. When the buffer plate 21 is impacted by falling rocks, it compresses the damping shock absorber 243 and the buffer spring 244 to play a buffering role, thereby achieving energy absorption. The plurality of damping shock absorbers 243 are spaced along the length direction of the spring sleeve 241. The buffer spring 244 is set to effectively absorb and consume a part of the impact energy during the compression process, and limit the excessive displacement of the movable spring plate 242, so as to ensure that the buffering process is smooth and controllable; each buffer spring 244 is sleeved on the outer periphery of the corresponding damping shock absorber 243. When the damping shock absorber 243 is compressed, the buffer spring 244 will also be compressed to further absorb the remaining impact energy. At the same time, the buffer spring 244 provides a restoring force to help the movable spring plate 242 return to its original position after the impact, so as to prepare for the next possible impact. That is, in this embodiment, through the coordinated work of the damping shock absorber 243 and the buffer spring 244, the buffer assembly 24 can effectively absorb the impact energy caused by falling rocks.

[0059] like Figure 2 As shown, the fixing device 3 includes a plurality of groups of resistance cones 31 and two groups of relatively arranged plug-in components 32. The plurality of groups of resistance cones 31 are arranged at the bottom of the main structure 1 (that is, the bottom of the structural base plate 14). The resistance cones 31 can penetrate into the surface of the slope and penetrate into the slope to provide strong grip, thereby effectively preventing the main structure 1 from horizontal displacement or overturning, and will not move easily even if subjected to strong external forces (such as rockfall impact); in addition, the plurality of resistance cones 31 are evenly distributed, which can disperse the pressure from above to a larger area, reduce local stress concentration, and thus improve the durability and reliability of the overall structure. One group of plug-in components 32 is installed on the first side 11, and the other group of plug-in components 32 is installed on the second side 12, providing additional mechanical locking points, further enhancing the connection strength between the main structure 1 and the slope, and ensuring the stability of the system.

[0060] It should be noted that the multiple groups of resistance cones 31 are distributed in a rectangular shape at the bottom of the structural base plate 14 to increase the friction between the structural base plate 14 and the ground, thereby improving the installation and fixing effect.

[0061] like Figure 3 and Figure 4As shown, the plug-in assembly 32 includes a first plate 321, a second plate 322, a third plate 323 and a fixing tooth 324.

The slide rail 51 is a guide rail to ensure that the positioning rod 53 can slide smoothly along a predetermined path, while limiting the lateral movement of the positioning rod 53 to ensure the consistency of its movement direction. The outer peripheral side of the positioning rod 53 is provided with a spiral blade 54. When the positioning rod 53 rotates, the spiral blade 54 will spirally cut into the slope to provide additional grip and anchoring effect; the drill bit 55 is arranged at one end of the positioning rod 53 for drilling into the slope surface to further enhance the fixing ability of the positioning rod 53, and the other end of the positioning rod 53 is externally connected to a driving device to drive the positioning rod 53 to move.

[0064] It can be understood that the external drive device of this embodiment provides power for the positioning rod 53, so that it can slide and / or rotate along the slide rail 51, thereby firmly fixing the positioning rod 53 on the slope. The drive device can be selected as an electric, hydraulic or manual form as needed, and its type is not particularly limited here. The drive device is a conventional drive structure.

[0065] In this embodiment, the spiral blades 54 and the drill bit 55 on the positioning rod 53 can create a stable fixed point on the slope surface to ensure that the main structure 1 will not be horizontally displaced or overturned. In addition, since the positioning rod 53 is slidably connected to the slide rail 51 through the second slide bar 52, the position of the positioning rod 53 can be adjusted according to actual conditions to ensure the best fixing effect, thereby increasing the flexibility of the system and enabling it to adapt to different terrain conditions.

The top of the positioning rod 53 is fixedly connected with a hexagonal docking joint 58, which is docked with an electric device (that is, a driving device), thereby facilitating the user's drilling operation.

The laser speed meter 63 adopts the principle of laser ranging. It emits a laser beam to the object to be measured, receives the reflected wave of the laser beam, and records the time difference, so as to determine the distance between the object to be measured and the test point. Laser speed measurement is a method of obtaining the moving distance of the object being measured within two specific time intervals through laser ranging. The moving distance of the object being measured within the time period is obtained, thereby obtaining the moving speed of the object being measured, which is used to monitor the speed of falling rocks in real time and provide accurate speed data. When an abnormally high speed is detected, the early warning mechanism can be triggered immediately to buy time for emergency response. The principles of the three-dimensional scanner 64 mainly include the structured light scanning principle and the laser scanning principle. The structured light scanning principle projects a specific pattern of light onto the surface of an object, and then constructs a three-dimensional model by analyzing the reflected light. The laser scanning principle uses a laser beam to scan the surface of an object, and obtains the three-dimensional information of the object by measuring the reflection time or phase change of the laser beam, so as to perform three-dimensional modeling of falling rocks and provide detailed shape, size and motion trajectory information to help assess their potential degree of harm.

The side of the base 69 away from the second side surface 12 has a plurality of locking holes 692 corresponding to the through holes 671. The locking member 610 is inserted into the locking hole 692 through the through hole 671 to lock the base 69 and the adjustment disk 67, so that the adjustment disk 67 is fixed at the desired position to ensure that the monitoring angle remains unchanged, thereby realizing the angle rotation adjustment of the motion identification monitor 651 subsequently installed thereon.

One end of the motion identification monitor 651 is equipped with multiple groups of fill lights 652, which are distributed in a ring shape at one end of the motion identification monitor 651. The use of multiple groups of fill lights 652 can fill in the falling rocks, thereby improving the monitoring effect; the other end of the motion identification monitor 651 is plugged with an identification unit wireless signal transmitter 653. Based on the characteristics of radio wave transmission and electromagnetic waves, the identification unit wireless signal transmitter 653 modulates the audio and video signals onto radio waves and then transmits them through the antenna.

When abnormal behavior is detected, the system will immediately issue an early warning and mark it. The above monitoring method can also be implemented by conventional methods and is not specifically limited here. In addition, the above abnormal behavior can be set according to actual needs and is not specifically limited here.

[0073] In this embodiment, the photovoltaic panel 611 collects solar energy and converts it into electrical energy. The monitoring device 6 is self-powered and reduces dependence on the traditional power grid. At the same time, the double-headed servo motor 615 cooperates with the driving gear 616 and the driven gear 614, so that the photovoltaic panel 611 can automatically adjust the angle according to the lighting conditions to ensure maximum energy collection efficiency.

The structural liquid outlet plate 73 and the structural ring 76 are fixedly connected to the inner wall of the check inner tube 71. The two ends of the retraction spring 74 are respectively abutted against the structural liquid outlet plate 73 and the movable sealing structure 75. The structural liquid outlet plate 73 provides support for the upper component, which is connected to the movable sealing structure 75 through the retraction spring 74. A plurality of groups of limiting blocks 751 are fixedly connected to the outer side of the movable sealing structure 75.

[0076] The movable sealing structure 75 includes a movable sealing plate 752 and a sealing inner ring 753. The top of the retraction spring 74 is fixedly connected to the movable sealing plate 752. The top of the structural ring 76 is installed with a sealing inner ring 753. The inner wall of the check inner tube 71 is provided with a plurality of structural wall blocks 713. The plurality of structural wall blocks 713 are distributed in an annular shape on the inner wall of the check inner tube 71 to limit the retraction spring 74. The outer side of the movable sealing plate 752 is fixedly connected to a plurality of limiting blocks 751. The plurality of limiting blocks 751 are distributed in an annular shape on the outer side of the movable sealing plate 752. The retraction force of the retraction spring 74 presses the movable sealing plate 752 against the structural ring 76 and the sealing inner ring 753, thereby realizing the sealing inside the check inner tube 71. When the pressure in the liquid storage tank 411 increases, the movable sealing plate 752 can be pushed to overcome the retraction force of the retraction spring 74 and move upward, so that the liquid wall groove 712 can be opened to allow the electrolyte to be discharged, and when the pressure in the box is reduced, the retraction force of the retraction spring 74 can be used to reset the movable sealing plate 752 and reseal it, so as to prevent the electrolyte from flowing back and ensure the early warning effect.

[0077] like Fig.14As shown, it also includes a heat dissipation device 8, which includes a water pump 81, a water outlet pipe 82, a heat dissipation pipe 83, a heat exchange fin 84, a reflux pipe 85 and a reflux solenoid valve 86. The water pump 81 is installed on the outside of the liquid storage cylinder 413, and the water pump 81 is connected to the bottom of the liquid storage cylinder 413 through the water pump pipe, and the water pump 81 is connected to one end of the heat dissipation pipe 83 through one end of the water outlet pipe 82, and the other end of the heat dissipation pipe 83 is connected to the top of the liquid storage cylinder 413.

A reflux solenoid valve 86 is installed on the outside of the reflux pipe 85. The reflux solenoid valve 86 is opened to make the reflux pipe 85 unobstructed, thereby realizing the withdrawal of electrolyte in the liquid storage cylinder 413 and re-injecting the electrolyte into the liquid storage tank 411 for reuse.

[0078] It should be noted that the heat dissipation pipe 83 is a serpentine structure. The heat dissipation device 8 of this embodiment also includes an assembly base plate 87, assembly bolts 88 and a pipe support plate 89.

[0079] When the water pump 81 is powered on, the electrolyte in the liquid storage cylinder 413 can be pumped out through the water pump pipe, and the electrolyte can be injected into the heat dissipation pipe 83 through the water outlet pipe 82. The heat exchange with the air is achieved through the contact between the heat dissipation pipe 83 and multiple sets of heat exchange fins 84 and the air, so that the electrolyte can be cooled to avoid the increase of pressure in the cylinder and the occurrence of dangerous situations caused by the heating of the electrolyte when the power is turned on.

[0080] Working principle:

[0081] The user places the structural base plate 14 at the designated position, and then the user drives the second plate 322, the first plate 321 and the fixing teeth 324 into the soil by using a hammer or other tool. Then the user inserts the hexagonal drill rod of an electric drill or other equipment into the hexagonal joint 58 at the top of the positioning rod 53 and rotates the positioning rod 53 on the sliding bearing rod 56 by using the electric drill. The positioning rod 53 is moved downward along the second slide groove 57 and penetrates into the soil by using the outer spiral blade 54 and the bottom drill bit 55 of the positioning rod 53, thereby achieving the fixation of the entire device.

[0082] Then the user adjusts the angle of the upper motion recognition monitor 651 and the photovoltaic panel 611 by the movable connection between the adjustment disk 67 at the bottom of the rod seat 613 and the base 69 and the insertion of the locking piece and the locking hole 692, and adjusts the elevation angle of the motion recognition monitor 651 by the movable connection between the deflection head 662 and the deflection seat 661 and the locking of the locking bolt 663, and drives the driving gear 616 on the driving shaft to rotate through the double-headed servo motor 615, and the driven gear 614 on the shaft 612 is engaged with the driving gear 616, so that the elevation angles of the two sets of photovoltaic panels 611 can be synchronously adjusted, thereby completing the adjustment function of the device;

[0083] During use, the falling rocks roll onto the structural bottom plate 14 through the first inclined surface 3231, and the falling rocks are buffered by the arc surface on the buffer plate 21 and the multiple groups of damping shock absorbers 243 and buffer springs 244 in the spring sleeve plate 241, thereby realizing its protective function;

[0084] When a rockfall occurs, the laser speed meter 63 will monitor the speed of the rockfall, the three-dimensional scanner 64 will monitor the size of the rockfall, and the motion recognition monitor 651 can monitor the rockfall and transmit the signal to the control unit cabinet 62 and the mobile device of the staff through the wireless signal transmitter for recording and reminder;

[0085] When a rockfall occurs, the rockfall squeezes the buffer plate 21, and the buffer plate 21 drives the contact plate 422 and the telescopic sleeve 421 to retract and move backward, thereby reducing the volume of the liquid storage box 411 and increasing the hydraulic pressure in the box, so that the electrolyte can overcome the retraction force of the movable sealing plate 752 in the check inner tube 71 and the retraction force of the retraction spring 74 to move upward to the top of the check inner tube 71, so that the liquid outlet wall groove 712 is opened, and the electrolyte is injected into the liquid storage cylinder 413 from the liquid outlet pipe 412. After the hydraulic pressure in the box is reduced, the retraction force of the retraction spring 74 can drive the movable sealing plate 752 to reset and reseal the check inner tube 71, so that the liquid outlet pipe 41 2. The electrolyte is blocked and remains in the liquid storage cylinder 413. Since the internal volume of the liquid storage cylinder 413 is smaller than the telescopic sleeve 421 of the liquid storage box 411, the electrolyte will fill the liquid storage cylinder 413 after being injected into the liquid storage cylinder 413. Through the conductive property of the electrolyte, the power input conductive rod 431 and the power output conductive rod 432 are connected, and the power input line 435 and the power output line are connected, thereby completing the power supply to the early warning light box 441, so that the early warning light box 441 emits light to remind the staff and surrounding personnel, and transmits the signal through the early warning unit wireless signal transmitter 445 on the light box controller 443, thereby realizing its early warning function;

[0086] When the electrolyte in the liquid storage cylinder 413 is conductive, the user needs to energize the water pump 81. When the water pump 81 is energized, the electrolyte will be pumped into the heat dissipation pipe 83 through the water pump pipe, and then re-injected into the liquid storage cylinder 413 after heat exchange with the air through the heat dissipation pipe 83 and the heat exchange fins 84, thereby cooling the electrolyte and ensuring the stability of the device. Finally, after dealing with the fallen rocks, the user can open the reflux solenoid valve 86 on the reflux pipe 85, and re-inject the electrolyte into the liquid storage tank 411 through the water pump 81 for reuse, thereby realizing the early warning protection function of a slope dangerous rock and rock fall protection system that can be monitored and warned.

[0087] In summary, the embodiment of the present invention provides a rockfall protection system, which changes the volume of the box body when the telescopic sleeve 421 outside the liquid storage box 411 is squeezed, so that the electrolyte hydraulic pressure in the box increases, so that the electrolyte can be squeezed from the liquid outlet pipe 412 into the liquid storage cylinder 413, and the power input conductive rod 431 and the power output conductive rod 432 are connected through the conductivity of the electrolyte, and the power input line 435 is further connected with the power output line and supplies power to the early warning light box 441, and an alarm threshold is set through the light box controller 443, and the early warning information can be sent to the monitoring personnel and the protected person through 5G+Beidou mode and sending text messages, and the surrounding personnel are reminded in this way, so as to realize the early warning function of the device. In addition, the rolling speed, volume size and movement trajectory of the stone are monitored by the laser speed meter 63, the three-dimensional scanner 64, the motion recognition monitor 651 and the identification unit wireless signal transmitter 653, and the speed and height of the rolling process of the rockfall are displayed, so as to facilitate the staff to monitor and record the protection operation. Furthermore, the present invention extracts the electrolyte in the liquid storage cylinder 413 through the water pump 81, and cools the electrolyte through contact heat exchange between the serpentine heat dissipation pipe 83 and the heat exchange fins 84 and the air, thereby preventing the temperature increase of the electrolyte after power is turned on and affecting the air pressure in the cylinder and the stability of the early warning structure; in addition, the present invention also fixes the entire device by fixing the plug plate and the guide plug plate deep into the soil, and the spiral leaves and the drill bit 55 on the positioning rod 53 drill into the soil, and the buffer protection against falling rocks is achieved through the guidance of the arc surface of the buffer plate 21 and the multiple groups of damping shock absorbers 243 and buffer springs 244 in the spring sleeve plate 241.

[0088] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
