[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0027] When constructing infrastructure such as pipelines and roads on a slope, for example, for pipeline laying construction, the construction site is generally a remote area such as a mountainous area. When the construction site is a slope, a horizontal construction site for pipeline laying needs to be excavated on the slope, and then the construction personnel lay the pipeline on the horizontal construction site. In this process, the rolling stones on the slope above the construction site may roll down to the construction site, which not only damages the construction site but also endangers the personal safety of the construction personnel.

[0028] Currently, to solve the problem of rolling stones on the slope, the rolling stones on the slope are manually cleaned before and during construction. However, due to the long line of the construction site, the large area of the slope that needs to be cleaned, and the complex environment of the slope, manual cleaning is costly and difficult. Moreover, manual cleaning can only clean the rolling stones that can be predicted to roll down, and those hidden rolling stones are easily ignored, thus leaving a safety hazard and threatening the personal safety of the construction personnel.

[0029] Some intelligent alarm methods for rolling stones have been proposed in the prior art. However, these intelligent alarm methods have many components and complex connection relationships, and require a high level of environmental and network support due to the large number of electronic devices. However, for the construction phase of slope infrastructure construction, the intelligent rolling stone alarm device needs to be installed on the slope, which is easily affected by weather such as rain and snow. Moreover, due to the remote location, the network is unstable, resulting in low precision. Furthermore, slope infrastructure construction is carried out in sections, and after the current construction section is completed, the next section is constructed. At this time, the rolling stone alarm device installed on the slope corresponding to the current construction section needs to be disassembled and installed on the slope corresponding to the next construction section, which is a large workload and affects the progress of infrastructure construction. Therefore, the intelligent alarm method for rolling stones in the prior art is not suitable for the construction phase of slope infrastructure construction.

[0030] Therefore, to solve the above technical problems in the prior art, the application provides a slope rock rolling speed reduction, blocking, protection and safety alarm device for construction operation, which is characterized in that a first protection alarm device and a second protection alarm device are installed on a slope above a construction site, wherein the first protection alarm device comprises a plurality of first protection nets, each of which is provided with a first alarm device, and when a rock rolls onto the first protection net, the first alarm device sends a first alarm information; the second protection alarm device comprises a plurality of second protection nets, each of which is provided with a second alarm device, and when a rock rolls onto the second protection net, the second alarm device sends a second alarm information, so that when the construction personnel receive the first alarm information, they realize that a rock is rolling down, and quickly evacuate the current position, and when the second alarm information is received, the current position of the rock is known, so that the time for continuing construction is determined, not only the rock is blocked by the two protection nets, i.e. the first protection net and the second protection net, and the rolling speed of the rock is reduced, but also the rock is alarmed, and the slope rock rolling speed reduction, blocking, protection and safety alarm device for construction operation has a simple structure, is convenient to disassemble and assemble, and has low requirements for environment and network.

[0031] Figure 1 FIG. 1 is a front view of an installation scene of a slope rock rolling speed reduction, blocking, protection and safety alarm device for construction operation according to an embodiment of the application, Figure 2 FIG. 2 is a side view of an installation scene of a slope rock rolling speed reduction, blocking, protection and safety alarm device for construction operation according to an embodiment of the application. Figure 1 And Figure 2 As shown in FIGS. 1-2, the slope rock rolling speed reduction, blocking, protection and safety alarm device for construction operation comprises a first protection alarm device 100 and a second protection alarm device 200, wherein the first protection alarm device 100 and the second protection alarm device 200 are located on a slope 400 above a construction site 300, and are laid along the length direction of the construction site 300, and the first protection alarm device 100 is located above the second protection alarm device 200;

[0032] The first protection alarm device 100 comprises a plurality of first protection nets 110, each of which is provided with a first alarm device (not shown in the figure), and when a rock 500 rolls onto the first protection net 110, the first alarm device sends a first alarm information, which is used to prompt the construction personnel that a rock is rolling down, and start to evacuate the position;

[0033] The secondary protection alarm device 200 comprises a plurality of secondary protection nets 210, the plurality of secondary protection nets 210 are installed in one-to-one correspondence with the plurality of primary protection nets 110, and each of the plurality of secondary protection nets 210 is installed with a second alarm device (not shown in the figure), when the rolling stone 500 rolls onto the secondary protection net 210, the second alarm device sends a second alarm information, the second alarm information is used to prompt the current position of the rolling stone 500 to the construction personnel, so that the construction personnel determines the time of continuing construction according to the current position of the rolling stone 500.

[0034] The distance between the primary protection net 110 and the secondary protection net 210 located in the same vertical plane is a first distance, and the first distance is the time length within which the construction personnel can evacuate from the current position when the rolling stone rolls the first distance.

[0035] In the embodiment, the primary protection alarm device 100 comprises a plurality of primary protection nets 110, by setting a plurality of primary protection nets 110, instead of using a large net, the volume and quantity of each primary protection net 110 can be reduced, and the disassembly, replacement and maintenance are facilitated.

[0036] The secondary protection alarm device 200 comprises a plurality of secondary protection nets 210, which is also to reduce the volume and quantity of each secondary protection net 210, and facilitate disassembly, replacement and maintenance.

[0037] The first distance is the time length within which the construction personnel can evacuate from the current position when the rolling stone rolls the first distance, and the first distance is the shortest rolling distance of the rolling stone from the primary protection net 110 to the secondary protection net 210, so that the first distance can ensure that the construction personnel can evacuate from the construction site 300 when the rolling stone 500 rolls onto the secondary protection net 210, thereby ensuring the safety of the construction personnel.

[0038] The primary protection net 110 is located above the secondary protection net 210, so as to avoid that the rolling stone 500 does not roll onto the primary protection net 110 but directly rolls onto the secondary protection net 210, thereby causing the construction personnel to be difficult to evacuate from the current position in time, thereby causing a safety accident to occur. In addition, the plurality of secondary protection nets 210 are installed in one-to-one correspondence with the plurality of primary protection nets 110, that is, the head and tail of the primary protection net 110 and the secondary protection net 210 are located on the same vertical plane.

[0039] The first alarm device is installed on each primary protective net 110. When the rolling stone 500 rolls and hits the primary protective net 110, the corresponding first alarm device sends a first alarm information. The construction personnel receive the first alarm information and know that the rolling stone 500 rolls. The construction personnel start to evacuate from the current position. At this time, the primary protective net 110 also blocks the rolling stone 500, reduces the rolling speed of the rolling stone 500, and even can intercept the rolling stone 500 in the primary protective net 110.

[0040] The second alarm device is installed on each secondary protective net 210. When the rolling stone 500 that is not blocked by the primary protective net 110 rolls and hits the secondary protective net 210, the corresponding second alarm device sends a second alarm information. The construction personnel receive the second alarm information and know that the rolling stone 500 has rolled to the secondary protective net 210. Then, the construction personnel can wait for the rolling stone to break through the secondary protective net 210 and roll to the construction site 300. If the rolling stone 500 has not rolled to the construction site 300 after a preset time, a construction personnel can be arranged to go to the construction site 300 to check the state of the rolling stone 500 and confirm whether the rolling stone 500 will roll from the secondary protective net 210 to the construction site 300. If the rolling stone 500 will not roll from the secondary protective net 210 to the construction site 300, the construction personnel can return to the construction site 300 to continue construction. The preset time can be obtained according to the test. At this time, the secondary protective net 210 also blocks the rolling stone 500, can intercept the rolling stone 500 in the secondary protective net 210, and further reduces the rolling speed of the rolling stone 500 that is not blocked, reduces the rolling speed of the rolling stone to the construction site 300, and reduces the damage to the construction site.

[0041] In the embodiment, the first protection alarm device 100 and the second protection alarm device 200 are installed on the slope 400 above the construction site 300, wherein the first protection alarm device 100 comprises a plurality of first protection nets 110, each of which is provided with a first alarm device, and when the rolling stone 500 rolls onto the first protection net 110, the first alarm device sends a first alarm information; the second protection alarm device 200 comprises a plurality of second protection nets 210, each of which is provided with a second alarm device, and when the rolling stone rolls onto the second protection net 210, the second alarm device sends a second alarm information, so that when the construction personnel receives the first alarm information, it is known that the rolling stone 500 rolls down, so as to quickly evacuate the current position, and when the second alarm information is received, the current position of the rolling stone is known, so as to determine the time for continuing construction, not only the rolling stone is blocked by the two protection nets, i.e. the first protection net and the second protection net, the rolling stone rolling speed is reduced, and the safety of the construction personnel is protected, but also the alarm of the rolling stone 500 is realized, the safety of the construction personnel is ensured, and the structure of the application is simple, easy to disassemble and assemble, and has low requirements on environment and network.

[0042] Optionally, as shown in Figure 1 , the slope rolling stone deceleration blocking protection and safety alarm device for construction work further comprises: a safety device 600, which is arranged at a position close to the slope 400 of the construction site 300. According to the rolling trajectory of the rolling stone, under the action of inertia, the rolling stone will fall in a parabolic curve to the construction site 300, therefore, the safety device 600 is arranged at the position close to the slope 400, and when the construction personnel know that the rolling stone hits the first protection net 110, they evacuate from the current position to the safety device, ensuring safety.

[0043] Among them, the safety device 600 can be a certain safety area, when selecting the safety area, the area corresponding to less rolling stones can be selected according to the characteristics of the slope 400, so as to reduce the probability of rolling stones rolling into the safety area and improve safety.

[0044] Optionally, the safety device 600 can be arranged at a position protruding to the slope 400 of the construction site 300. As shown in Figure 1 , the construction can be carried out towards the slope 400 at the position close to the slope 400, and a space protruding to the slope 400 is constructed, which is set as a safety area, which not only ensures the safety of the construction personnel, but also does not affect the construction.

[0045] Optionally, as shown in Figure 1As shown, the number of the safety devices 600 is determined according to the area of the construction site 300, so that the construction personnel can evacuate to the closest safety device 600 from the position of the construction personnel within the time length of the first distance of the rolling stone 500.

[0046] In this embodiment, the construction personnel are relatively dispersed during construction, and the area of the construction site 300 is relatively large, so if only one safety area is provided, it is difficult for the construction personnel to evacuate to the safety area within the time length of the first distance of the rolling stone 500. Therefore, generally, multiple safety areas need to be provided in the construction site 300.

[0047] Generally, the length of the construction site 300 is 200 meters, and the width can be ignored compared with the length. Therefore, the area of the construction site 300 can also be converted into the length of the construction site 300. According to the time length of the first distance of the rolling stone 500, the moving distance of the construction personnel within the time length is determined, so as to determine the position and number of the safety areas, and ensure the safety of the construction personnel.

[0048] Optionally, as shown in FIG. 1, the first protection net 110 and the second protection net 210 are arranged in a staggered manner. Figure 1 As shown, the first protection net 110 and the second protection net 210 are arranged in a staggered manner and the heads and tails are located on the same vertical plane.

[0049] The first protection net 110 and the second protection net 210 are arranged in a staggered manner and the heads and tails are located on the same vertical plane.

[0050] In this embodiment, the first protection net 110 and the second protection net 210 are installed one by one, that is, the head of the first protection net 110 and the head of the corresponding second protection net 210 are located on the same vertical plane, and the tail of the first protection net 110 and the tail of the corresponding second protection net 210 are located on the same vertical plane.

[0051] The first protection net 110 and the second protection net 210 are arranged in a staggered manner and the heads and tails are located on the same vertical plane.

[0052] Therefore, in the embodiment, the two adjacent first protective nets 110 are staggered up and down and have their heads and tails in the same vertical plane, and the two adjacent second protective nets 210 are staggered up and down and have their heads and tails in the same vertical plane. In this way, the animals can pass through the space between the staggered protective nets, and the rolling stones 500 on the slope 400 can also pass through the first protective nets 110 and the second protective nets 210 to trigger the alarm.

[0053] Optionally, the first alarm device comprises a first ringer, and the second alarm device comprises a second ringer.

[0054] The ringtones of the first ringer and the second ringer are different.

[0055] In the embodiment, considering that the slope is located in an open area, it is inconvenient to use intelligent electronic devices to monitor and alarm the rolling stones, and the rolling stones have the characteristics of suddenness and randomness, which is inconvenient for human observation. Therefore, the first ringer is installed on the first protective net 110, and the second ringer is installed on the second protective net 210. When the rolling stone 500 rolls and hits the first protective net 110, the first protective net 110 vibrates to drive the first ringer to vibrate and ring. When the rolling stone 500 rolls and hits the second protective net 210, the second protective net 210 vibrates to drive the second ringer to vibrate and ring. The first protective net 110 and the second protective net 210 select different ringers, so that the ringtones of the first ringer and the second ringer are different. In this way, the ringtones can not only convey the information of the rolling stone 500, but also convey the current position of the rolling stone 500.

[0056] It should be noted that when selecting the first ringer and the second ringer, a ringer with less interference is selected to avoid the problem that the first ringer and the second ringer are blown by the wind to ring.

[0057] Optionally, the first alarm device and the second alarm device each comprise a loudspeaker. When the first protective net 110 and the second protective net 210 are hit by the rolling stone 500, the loudspeaker is turned on and plays a voice corresponding to the installation position of the loudspeaker.

[0058] In the embodiment, each first protective net 110 and each second protective net 210 corresponds to a loudspeaker. The loudspeaker can be directly installed on the first protective net 110 and the second protective net 210. Each first protective net 110 and each second protective net 210 is numbered, and the voice of the loudspeaker installed on the first protective net 110 and the second protective net 210 corresponds to the number of the protective net at the installation position. The voice can be recorded in advance. For example, for the first first protective net, the voice of the corresponding loudspeaker can be "the first first protective net is hit by a rolling stone".

[0059] For any loudspeaker, its control switch can be controlled by the vibration movement of the protective net, for example, when the rolling stone 500 hits the first protective net 110, the first protective net 110 vibrates and opens the loudspeaker through the vibration movement. The playing voice of the loudspeaker is automatically stopped after a preset time length, wherein the time length of the playing voice of the loudspeaker can be set in advance. Thus, by setting the loudspeaker, timely alarm is given when the rolling stone 500 rolls down, and the safety of the construction personnel is ensured.

[0060] Optionally, the slope rolling stone deceleration blocking protection and safety alarm device for construction work further comprises a collision detection device, at least one collision detection device is installed on the first protective net 110 and the second protective net 210, and the collision detection device is connected with the loudspeaker.

[0061] The collision detection device is used to detect the triggering of the loudspeaker when the first protective net 110 and the second protective net 210 are hit by the rolling stone 500.

[0062] In this embodiment, the first protective net 110 is taken as an example for description:

[0063] The collision detection device can be a pressure sensor, which is installed in front of the first protective net 110. According to the length of the first protective net 110, multiple pressure sensors can be installed, so that when the rolling stone 500 rolls onto the first protective net 110, it contacts the pressure sensor, so that the pressure sensor detects the pressure and thus opens the loudspeaker. At this time, due to the staggered arrangement of the adjacent two first protective nets 110 and the staggered arrangement of the adjacent two second protective nets 210, the probability of the animal touching the protective net is small according to the animal's instinct, and thus the risk of the animal mistakenly touching the pressure sensor is small.

[0064] The process of opening the loudspeaker through the pressure sensor, for example, can be that the pressure sensor converts the pressure signal into an electric signal, controls the relay to be turned on through the electric signal, and thus controls the loudspeaker to be opened through the relay. The specific process can refer to the prior art, and will not be described here. It should be noted that although this method uses electronic devices, the number of electronic devices is relatively small, the connection is simple, the disassembly and assembly are convenient, the influence on the construction period is small, and the alarm accuracy can be improved by using this method.

[0065] Optionally, the collision detection device comprises an acceleration sensor.

[0066] The acceleration sensor is used to detect the impact force when the first protective net 110 and the second protective net 210 are hit by the rolling stone 500, and to control the volume of the loudspeaker according to the impact force, wherein the volume of the loudspeaker is positively correlated with the impact force.

[0067] In the embodiment, the pressure sensor adopts an acceleration sensor. When the rolling stone 500 collides with the first protective net 110, the rolling stone 500 passes through the acceleration sensor. The pressure detected by the acceleration sensor is related to the weight and speed of the rolling stone 500. The pressure is converted into an electric signal corresponding to the pressure. The switch of the loudspeaker is controlled by the knob. The knob can not only turn on the loudspeaker, but also adjust the volume of the loudspeaker by rotating the knob. Therefore, after the acceleration sensor converts the pressure into an electric signal, the electric signal is connected to the single-chip microcomputer. The motor is controlled by the single-chip microcomputer, so as to turn on the loudspeaker and control the volume of the loudspeaker. Therefore, the construction personnel can not only know that the rolling stone rolls down, but also know the size and speed of the rolling stone 500 according to the volume of the loudspeaker, so as to infer the risk brought by the rolling stone, thereby improving the alarm efficiency and practicability of the application.

[0068] It should be noted that although the acceleration sensor, the single-chip microcomputer, the motor and other electronic devices are used in the embodiment, the functions are single, easy to realize, and the electronic devices are small in size and easy to disassemble and assemble.

[0069] Figure 3 A flow chart of the slope rolling stone deceleration blocking protection and safety alarm method for construction operation provided by the embodiment is shown in FIG. 1. Figure 3 As shown in FIG. 1, the method comprises the following steps.

[0070] S301, when the first protective net is hit by the rolling stone, the first alarm device sends the first alarm information. The first alarm information is used to prompt the construction personnel that the rolling stone rolls down and to start to evacuate the position.

[0071] S302, when the second protective net is hit by the rolling stone rolling down from the first protective net, the second alarm device sends the second alarm information. The second alarm information is used to prompt the construction personnel the current position of the rolling stone, so that the construction personnel can determine the time for continuing construction according to the current position of the rolling stone.

[0072] The slope rolling stone deceleration blocking protection and safety alarm method for construction operation provided by the embodiment can be applied to the slope rolling stone deceleration blocking protection and safety alarm device provided by any of the above embodiments. The implementation principle and beneficial effects are similar, and will not be repeated here.
