[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] When constructing infrastructure such as pipelines and roads on a slope, for example, for pipeline laying construction, the construction site is generally in a remote area such as a mountainous area. When the construction site is a slope, it is necessary to dig a horizontal construction site on the slope to facilitate pipeline laying, and then the construction workers lay the pipeline on the horizontal construction site. In this process, there is a problem that rocks on the slope above the construction site roll down to the construction site, which will not only damage the construction site, but also endanger the personal safety of the construction workers.

[0031] At present, the problem of rolling rocks on slopes is mainly solved by manual cleaning before and during construction. However, due to the long construction site, the large area of ​​slope to be cleaned and the complex slope environment, manual cleaning is costly and difficult. In addition, manual cleaning can only clean the rocks that are predicted to roll down, while those potential rocks that may roll down are easily overlooked, leaving safety hazards and threatening the personal safety of construction workers.

[0032] Among them, some existing technologies have also proposed some intelligent ways to alarm for rolling stones, but these intelligent alarm methods have many components and complex connection relationships. In addition, due to the large number of electronic devices, the requirements for the environment and network are relatively high. However, for the construction stage of slope infrastructure construction, the intelligent alarm equipment for rolling stones needs to be installed on the slope, which is easily affected by weather, such as rain and snow. Moreover, since it is generally located in a more remote area, the network is unstable, resulting in low accuracy. In addition, the slope infrastructure is constructed in sections. After the current construction section is completed, the next section is constructed. At this time, the rolling stone alarm equipment installed on the slope corresponding to the current construction section needs to be disassembled and then installed on the slope corresponding to the next construction section. The workload of equipment disassembly and assembly is large, which affects the progress of infrastructure construction. Therefore, the existing method of alarming rolling stones in an intelligent way is not suitable for the construction stage of slope infrastructure construction.

[0033] Therefore, in order to solve the technical problems in the above-mentioned prior art, the present application proposes a slope rock rolling deceleration, blocking protection and safety alarm device and method for construction operations, by installing a first-level protection alarm device and a second-level protection alarm device on the slope above the construction site, wherein the first-level protection alarm device includes multiple first-level protection nets, and the multiple first-level protection nets are all equipped with a first alarm device. When the rock rolls down onto the first-level protection net, the first alarm device sends out a first alarm message; the second-level protection alarm device includes multiple second-level protection nets, and the multiple second-level protection nets are installed in a one-to-one correspondence with the multiple first-level protection nets, and the multiple second-level protection nets are all equipped with a second alarm device. When the rock rolls down onto the secondary protection net, the second alarm device sends out a second alarm message. When the construction personnel receive the first alarm message, they will be aware of the rock rolling down and quickly evacuate the current position. When they receive the second alarm message, they will know the current position of the rock and determine the time to continue construction. Not only can the two-level protection nets, i.e., the primary protection net and the secondary protection net, be used to block the rock and reduce the speed of the rock rolling, but also an alarm for the rock rolling can be realized. In addition, the slope rock rolling deceleration, blocking protection and safety alarm device for construction operations proposed in this application has a simple structure, is easy to disassemble and assemble, and has low requirements on the environment and network.

[0034] Figure 1 This is a front view of an installation scene of a slope rolling stone deceleration, blocking, protection and safety alarm device for construction work provided by an embodiment of the present application. Figure 2 A side view of the installation scene of the slope rolling stone deceleration, blocking, protection and safety alarm device for construction work provided in one embodiment of the present application. Figure 1 and Figure 2As shown, the slope rolling stone deceleration blocking protection and safety alarm device for construction work includes: a primary protection alarm device 100 and a secondary protection alarm device 200, wherein the primary protection alarm device 100 and the secondary protection alarm device 200 are both located on the slope 400 above the construction site 300 and are laid along the length direction of the construction site 300, and the primary protection alarm device 100 is located above the secondary protection alarm device 200;

[0035] The primary protection alarm device 100 includes a plurality of primary protection nets 110, each of which is equipped with a first alarm device (not shown in the figure). When the rock 500 rolls down onto the primary protection net 110, the first alarm device sends out a first alarm message, which is used to remind the construction personnel that there is a rock rolling down and they start to evacuate their location.

[0036] The secondary protection alarm device 200 includes a plurality of secondary protection nets 210, which are installed one by one with the plurality of primary protection nets 110, and a second alarm device (not shown in the figure) is installed on each of the plurality of secondary protection nets 210. When the rolling stone 500 rolls onto the secondary protection net 210, the second alarm device sends a second alarm message, and the second alarm message is used to remind the construction personnel of the current position of the rolling stone 500, so that the construction personnel can determine the time to continue the construction according to the current position of the rolling stone 500.

[0037] Among them, the distance between the primary protection net 110 and the secondary protection net 210 located on the same vertical plane is the first distance, and the first distance is the time duration for the rolling stone to roll down the first distance, during which the construction workers can evacuate from their location.

[0038] In this embodiment, the first-level protection alarm device 100 includes multiple first-level protection nets 110. By setting multiple first-level protection nets 110 instead of using one large net, the volume and number of each first-level protection net 110 can be reduced, making it easier to disassemble, replace and maintain.

[0039] The secondary protection alarm device 200 includes a plurality of secondary protection nets 210, which is also for reducing the volume and quantity of each secondary protection net 210 to facilitate disassembly, assembly, replacement and maintenance.

[0040] Among them, considering that it takes a certain amount of time for construction workers to evacuate the construction site 300 from the time they discover that a rock has rolled down, when installing the primary protection net 110 and the secondary protection net 210, tests can be carried out on the corresponding slopes 400. The rolling time of the rock can be obtained through the test, so as to determine the installation positions of the primary protection net 110 and the secondary protection net 210, so that the vertical distance between the primary protection net 110 and the secondary protection net 210 is a first distance, wherein the first distance is the time length corresponding to the distance that the rock has rolled down, during which the construction workers can evacuate their current position. Since the first distance is the shortest rolling distance for the rock to roll from the primary protection net 110 to the secondary protection net 210, the setting of the first distance can ensure that the construction workers can evacuate the construction site 300 when they find that a rock 500 has rolled down to the secondary protection net 210, thereby ensuring the safety of the construction workers.

[0041] The primary protection net 110 is located above the secondary protection net 210 to prevent the rolling stone 500 from rolling directly onto the secondary protection net 210 instead of onto the primary protection net 110, thereby making it difficult for construction workers to evacuate their current location in time, thereby causing a safety accident. In addition, multiple secondary protection nets 210 are installed in a one-to-one correspondence with multiple primary protection nets 110, that is, the head and tail of the primary protection net 110 and the secondary protection net 210 are both located on the same vertical plane.

[0042] A first alarm device is installed on each primary protection net 110. When the rock 500 rolls down and hits the primary protection net 110, the corresponding first alarm device sends a first alarm message. The construction personnel receive the first alarm message, learn the current location of the rock 500, and start to evacuate. At this time, the primary protection net 110 also blocks the rock 500, reduces the rolling speed of the rock 500, and may even intercept the rock 500 in the primary protection net 110.

[0043] A second alarm device is installed on each secondary protection net 210. When a rolling stone 500 that is not intercepted by the primary protection net 110 rolls down and hits the secondary protection net 210, the corresponding second alarm device sends a second alarm message. After receiving the second alarm message, the construction personnel know that the rolling stone 500 has now rolled down onto the secondary protection net 210. Then, the construction personnel can wait for the rolling stone to break through the secondary protection net 210 and roll down to the construction site 300. If the rolling stone 500 has not rolled down to the construction site 300 after a preset time, a construction personnel can be arranged to check the status of the rolling stone 500 at the construction site 300 to confirm whether the rolling stone 500 will roll down from the secondary protection net 210 to the construction site 300. When it is confirmed that the rolling stone 500 will not roll down from the secondary protection 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 experiments. At this time, the secondary protection net 210 also blocks the rolling stones 500, and may intercept the rolling stones 500 in the secondary protection net 210, and further reduce the rolling speed of the rolling stones 500 that are not intercepted by it, reduce the speed of the rolling stones rolling to the construction site 300, and reduce the damage to the construction site.

[0044] In this embodiment, a primary protection alarm device 100 and a secondary protection alarm device 200 are installed on the slope 400 above the construction site 300, wherein the primary protection alarm device 100 includes a plurality of primary protection nets 110, each of which is equipped with a first alarm device. When the rolling stone 500 rolls down onto the primary protection net 110, the first alarm device sends out a first alarm message; the secondary protection alarm device 200 includes a plurality of secondary protection nets 210, each of which is installed in a one-to-one correspondence with the plurality of primary protection nets 110, and each of which is equipped with a second alarm device. When the boulder rolls down onto the secondary protection net 210, the second alarm device sends out a second alarm message, so that when the construction personnel receive the first alarm message, they will know that a boulder 500 has rolled down, and thus quickly evacuate the current position. When they receive the second alarm message, they will know the current position of the boulder, and thus determine the time to continue construction. Not only can the boulder be blocked by two levels of protection nets, namely the primary protection net and the secondary protection net, the rolling speed of the boulder is reduced, and the construction personnel are protected, but the boulder 500 can also be alarmed to ensure the safety of the construction personnel. In addition, the present application has a simple structure, is easy to disassemble and assemble, and has low requirements on the environment and network.

[0045] Optional, such as Figure 1As shown, the construction work slope rolling stone deceleration blocking protection and safety alarm device also includes: a risk avoidance 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 to the construction site 300 in a parabola. Therefore, the risk avoidance device 600 is arranged at a position close to the slope 400. When the construction personnel know that the rolling stone hits the primary protection net 110, they evacuate from the current position to the risk avoidance device to ensure safety.

[0046] Among them, the risk avoidance device 600 can be a determined risk avoidance area. When selecting the risk avoidance area, an area with fewer rolling stones can be selected according to the characteristics of the slope 400 to reduce the probability of rolling stones rolling into the risk avoidance area and improve safety.

[0047] Optionally, the risk avoidance device 600 may be arranged at a position where the construction site 300 protrudes from the slope 400. Figure 1 As shown, construction can be carried out toward the slope 400 at a position close to the slope 400 to build a space protruding from the slope 400, and the space can be set as a refuge area, which can not only ensure the safety of the construction workers but also will not affect the construction.

[0048] Optional, such as Figure 1 As shown, the number of the risk avoidance devices 600 is determined according to the area of ​​the construction site 300, so that the construction workers can evacuate to the risk avoidance device 600 closest to the location of the construction workers within the duration of the rolling stone 500 rolling down the first distance.

[0049] In this embodiment, the construction workers are relatively dispersed during construction, and the area of ​​the construction site 300 is relatively large. Therefore, if only one refuge area is set up, it is difficult for the construction workers to evacuate to the refuge area within the time it takes for the rolling stone 500 to roll down the first distance. Therefore, multiple refuge areas generally need to be set up in the construction site 300.

[0050] Among them, the general length of the construction site 300 is 200 meters, and the width is negligible compared to the length. Therefore, the area of ​​the construction site 300 can also be converted into the length of the construction site 300. The moving distance of the construction workers within the first distance is determined according to the time it takes for the rolling stone 500 to roll down, thereby determining the location and number of the safe havens to ensure the safety of the construction workers.

[0051] Optional, such as Figure 1 As shown, two adjacent primary protection nets 110 are staggered up and down and their ends are on the same vertical plane;

[0052] Two adjacent secondary protection nets 210 are staggered up and down and their ends are on the same vertical plane.

[0053] In this embodiment, the first-level protection net 110 and the second-level protection net 210 are installed in a one-to-one correspondence, that is, the head of the upper first-level protection net 110 and the head of the corresponding second-level protection net 210 are located on the same vertical plane, and the tail and the tail of the corresponding second-level protection net 210 are located on the same vertical plane.

[0054] Connecting multiple primary protection nets 110 in series in a row and multiple secondary protection nets 210 in series in a row can ensure that when a rock 500 on the slope 400 corresponding to the construction section rolls down, an alarm is sounded through the primary protection net 110 and the secondary protection net 210, and there will be no situation where the rock 500 rolls down but does not touch the primary protection net 110 and the secondary protection net 210. However, since the slope is located in a remote area, animals may move on it, and the construction section is generally 200 meters long, this installation method will not only affect animal activities, but also cause damage to the protection net, for example, animals may be stuck in the protection net, and the animals may damage the protection net when they break free from it.

[0055] Therefore, in this embodiment, two adjacent primary protection nets 110 are staggered up and down and their ends are on the same vertical plane, and two adjacent secondary protection nets 210 are staggered up and down and their ends are on the same vertical plane. In this way, animals can pass through the space between the staggered protection nets, and it is also ensured that when the rolling stone 500 on the slope 400 rolls down, the primary protection net 110 and the secondary protection net 210 will sound an alarm.

[0056] Optionally, the first alarm device includes a first bell, and the second alarm device includes a second bell;

[0057] The ring tones of the first ring and the second ring are different.

[0058] In this embodiment, considering that the slope is located in an open area, it is not convenient to use intelligent electronic devices to monitor and alarm the rolling stones, and the sudden and random characteristics of the rolling stones make it difficult to observe manually. Therefore, a first bell is installed on the primary protection net 110, and a second bell is installed on the secondary protection net 210. When the rolling stone 500 rolls down and hits the primary protection net 110, the primary protection net 110 vibrates, thereby driving the first bell to vibrate and emit a ringing sound. When the rolling stone 500 rolls down and hits the secondary protection net 210, the secondary protection net 210 vibrates, thereby driving the second bell to vibrate and emit a ringing sound. Among them, the primary protection net 110 and the secondary protection net 210 select different bells, so that the ringing sounds of the first bell and the second bell are different. In this way, the ringing sound can not only transmit the information of the rolling stone 500, but also the information of the current position of the rolling stone 500.

[0059] It should be noted that when selecting the first bell and the second bell, the bell that is less susceptible to interference should be selected to avoid the problem of the first bell and the second bell being blown by the wind and making ringing sounds.

[0060] Optionally, both the first alarm device and the second alarm device include a speaker. When the primary protection net 110 and the secondary protection net 210 are hit by the rolling stone 500, the speaker is turned on and plays a voice corresponding to the installation position of the speaker.

[0061] In this embodiment, each first-level protection net 110 and each second-level protection net 210 corresponds to a speaker, and the speaker can be directly installed on the first-level protection net 110 and the second-level protection net 210. Each first-level protection net 110 and each second-level protection net 210 are numbered. Accordingly, the voice of the speaker installed on the first-level protection net 110 and the second-level protection net 210 corresponds to the number of the protection net corresponding to the installation position, wherein the voice can be recorded in advance. For example, for the first-level protection net No. 1, the voice of the corresponding speaker can be "There is a rolling stone rolling down at the first-level protection net No. 1."

[0062] For any speaker, its control switch can be controlled by the vibration movement of the protection net. For example, when the rolling stone 500 hits the primary protection net 110, the primary protection net 110 vibrates, and the speaker is turned on by the vibration movement. After the speaker plays the voice for a preset time, it automatically stops playing. The time for the speaker to play the voice can be set in advance. Therefore, by setting up the speaker, when the rolling stone 500 rolls down, an alarm is issued in time to ensure the safety of the construction workers.

[0063] Optionally, the slope rolling stone deceleration blocking protection and safety alarm device for construction work further includes a collision detection device, at least one collision detection device is installed on the primary protection net 110 and the secondary protection net 210, and the collision detection device is connected to a speaker;

[0064] The collision detection device is used to detect when the primary protection net 110 and the secondary protection net 210 are hit by the rolling stone 500 and trigger the speaker to turn on.

[0065] In this embodiment, the first-level protection net 110 is taken as an example for description:

[0066] The collision detection device may be a pressure sensor, which is installed in front of the primary protection net 110. Multiple pressure sensors may be installed according to the length of the primary protection net 110, so that when the rolling stone 500 rolls onto the primary protection net 110, it contacts the pressure sensor, so that the pressure sensor detects the pressure and turns on the speaker. At this time, since two adjacent primary protection nets 110 are staggered up and down and two adjacent secondary protection nets 210 are staggered up and down, according to the instinct of the animal, the probability of the animal touching the protection net is small, and therefore, the risk of the animal accidentally touching the pressure sensor is small.

[0067] Among them, the process of turning on the speaker through the pressure sensor can be, for example: the pressure sensor converts the pressure signal into an electrical signal, controls the relay to turn on through the electrical signal, and thus controls the speaker to turn on through the relay. The specific process can refer to the prior art and will not be repeated here. It should be noted that although this method uses electronic devices, the number of electronic devices is relatively small, the connection is simple, and it is easy to disassemble and assemble, which has little impact on the construction period, and this method can improve the accuracy of the alarm.

[0068] Optionally, the collision detection device includes: an acceleration sensor;

[0069] The acceleration sensor is used to detect the impact force of the primary protection net 110 and the secondary protection net 210 when they are hit by the rolling stone 500, and control the volume of the speaker according to the impact force, wherein the volume of the speaker is positively correlated with the impact force.

[0070] In this embodiment, the pressure sensor adopts an acceleration sensor. When the rolling stone 500 collides with the primary protection 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, and the pressure is converted into an electrical signal corresponding to the pressure size. The switch of the speaker is controlled by a knob. The knob can not only turn on the speaker, but also adjust the volume of the speaker by turning the knob. Therefore, after the acceleration sensor converts the pressure into an electrical signal, it is connected to the single-chip microcomputer, and the motor is controlled by the single-chip microcomputer to turn on the speaker and control the volume of the speaker. In this way, the construction personnel can not only know that the rolling stone has rolled down, but also know the size and speed of the rolling stone 500 according to the volume of the speaker, thereby inferring the risks brought by the rolling stone, thereby improving the alarm efficiency and practicality of the present application.

[0071] It should be noted that although electronic devices such as acceleration sensors, single-chip microcomputers, and motors are used in this embodiment, they have a single function and are easy to implement. In addition, these electronic devices are small in size and easy to assemble and disassemble.
