Description

Technical Field

[0001] The present invention relates to the technical field of river safety equipment, in particular to a device for preventing mud and rock flows in a river. Background Art

[0002] For mountain rivers in areas with relatively harsh geological conditions, in order to ensure the safety of the rivers, existing technology will install devices such as barrier nets along the relevant areas of the river. In this way, when mudslides or falling rocks occur on the mountains, the damage caused by mudslides and falling rocks to the flood control dikes on the river banks can be minimized, and the mudslides and falling rocks can be prevented from blocking the river.

[0003] Current river channel debris flow prevention devices generally use multiple barrier mechanisms to mitigate the damage caused by debris flows and falling rocks to river channels. Although the multiple barrier mechanisms protect river channels to a certain extent, they are limited in functionality and still have some technical shortcomings. When a debris flow or rockfall occurs on site, the relevant remote management personnel are unaware of it. Specifically, they cannot understand the distance between the debris flow or rockfall and the barrier mechanism, whether the barrier mechanism is damaged or tilted, or the amount and nature of the debris flow at the time of occurrence (for example, they cannot distinguish whether the debris flow or rockfall is caused by water erosion or by a landslide). As a result, if the debris flow prevention devices used in the river channel are damaged and not repaired in a timely manner, or if the debris flow earthwork and falling rocks are not cleared away in a timely manner, the river channel debris flow prevention devices will subsequently be unable to effectively ensure the safety of the river channel. Summary of the Invention

[0004] In order to overcome the drawbacks of the existing river channel mud and rock flow prevention devices due to structural limitations as described in the background technology, the present invention provides a river channel mud and rock flow prevention device that can be set up in multiple ways under the joint action of relevant mechanisms to provide good protection for relevant positions of the river channel. When mud and rock flows, rock falls, blocking steel ropes break, blocking steel frames tilt, etc. occur on site, the relevant remote management personnel can be notified by SMS in the first time, and data on the distance between the mud and rock flows and rock falls and the approximate number and nature of the mud and rock flows and rock falls can be sent to the remote management personnel. The remote management personnel can intuitively grasp the corresponding data without going to the site, which brings convenience to the relevant management personnel, and provides favorable technical support for timely cleaning of the site or maintenance of the corresponding mechanisms, ensuring stable and reliable operation of the equipment and safety of the river channel.

These are also connected to a tension sensor T (T1 or T2) via wires.

The mercury in the mercury switch TN is positioned vertically at the lower end of the housing, with two terminals located at the upper end. The transmitter heads of laser ranging modules T5 and T6 face the front of the fixed frame, and the laser beams emitted by the transmitter heads of the two laser ranging modules are in a cross configuration. Wires connect the two poles of solar panel G1, the two poles of battery G2, the power input pins 1 and 2 of laser ranging modules T5 and T6, the power input pins 1 and 2 of SMS module T3, the power input pins 1 and 2 of analog signal isolation collector conversion module T4, the power input pins 1 and 2 of 4G module T7, the power input pins 1 and 2 of tension sensor T (or T2 or T3) for the three-way height detection circuit, the power input pins 1 and 2 of resistor R3 for the property detection circuit, the power input pins 2 and 3 of resistor R4 for the steel rope break detection circuit, the emitter of transistor Q3, and one end of the mercury switch TN for the power input of the 12-way tilt detection circuit.

The six signal input terminals 6, 5, 4, 3, 8, and 7 of the analog signal isolation collector conversion module T4 and the other ends of the resistors R, R1, and R2 at the signal output ends of the three-way height detection circuit, the other end of the other copper sheet WN at the signal output end of the property detection circuit, and the signal output terminal 3 pins of the two sets of laser ranging modules T5 and T6 are respectively connected via wires; the three signal input terminals of the SMS module T3 and the collector of the transistor Q3 at the signal output end of the steel rope break detection circuit and the positive electrodes of the diodes VD, VD1, and VD2 at the signal output end of the three-way height detection circuit, and the other end of the mercury switch TN at the signal output end of the 12-way tilt detection circuit are connected via wires. Figure 1 、 2As shown, the present invention can be installed in multiple sets from front to back in areas requiring protection, providing enhanced protection for the river (fixed wire rope 7 and barrier wire rope 2 act as barriers against debris flows and falling rocks). Normally, solar panel G1, exposed to sunlight, generates approximately 12V of electricity to charge battery G2. This eliminates the need for power lines, saving costs and facilitating future management. Simultaneously, 12V battery G2 powers SMS module T3, analog signal isolation collector conversion module T4, 4G module T7, laser ranging modules T5 and T6, tilt detection circuit 3, height detection circuit 4, property detection circuit 5, and wire rope breakage detection circuit 9, enabling these circuits and modules to operate. After the wire rope break detection circuit is energized and working, if there is no debris flow, falling rocks, etc. to cause the wire rope to break, the metal wire X will not be disconnected, and the base and emitter of the transistor Q3 at both ends of the metal wire X will be short-circuited. The transistor Q3 will not be turned on, and the SMS module T3 will not send the first SMS message; if there is a debris flow, falling rocks, etc. to cause the wire rope to break, the metal wire X will be disconnected, and the base and emitter of the transistor Q3 at both ends of the metal wire X will no longer be short-circuited. The transistor Q3 will be turned on and the collector output will be low to the pin 3 of the SMS module T3. The SMS module T3 will then send out a SMS message stored internally (resistors R5 and R4 have the function of reducing voltage and limiting current). After the three-way height detection circuit is energized and working, when there is no debris flow falling on the front end of the barrier rope 2, the voltage signals output by the 3-pin of the three tension sensors T, T1, and T2 are relatively low. When there is debris flow falling on the front end of the barrier rope 2, since the barrier rope 2 is tightened, the voltage signals output by the 3-pin of the three tension sensors T or T1, T2 are relatively high. Specifically, when there is no debris flow falling on the front end of the barrier rope 2, the voltage signals output by the 3-pin of the tension sensor T or T1, T2 are relatively low (lower than 0.7V), and the transistor Q or Q1, Q2 will not be turned on. Then, the 4-pin of the SMS module T3 will not input a low-level signal and will not send the second SMS. When there is debris flow or falling rocks falling on the front end of the barrier rope 2 (mud and rock flow), the voltage signals output by the 3-pin of the tension sensor T or T1, T2 are relatively low (lower than 0.7V), and the transistor Q or Q1, Q2 will not be turned on. When the height of a debris flow or rockfall is relatively low, only the voltage signal output by the tension sensor T becomes high. When the height of a debris flow or rockfall is relatively high, the voltage signals output by the tension sensors T and T1 become high. When the height of a debris flow or rockfall is very high, the voltage signals output by the tension sensors T and T1 and T2 become even higher. The voltage signal output by pin 3 of the tension sensor T or T1 and T2 is relatively high, and the transistor Q or Q1 and Q2 will be turned on (resistors R, R1 and R2 have the function of voltage reduction and current limiting). The collector outputs a low level and enters pin 4 of the SMS module T3. Then, the SMS module T3 will send the second SMS message stored internally (through the above, as long as there is a debris flow or rockfall in front of the barrier rope 2, the SMS module will send the second SMS message).When the fixed frame 1 and the supporting frame 6 are not tilted, the mercury switch TN located at the upper end of the fixed frame 1 and the supporting frame 6 will not tilt, and the mercury liquid level of the mercury switch TN will not submerge the inner upper end terminal. In this way, the low level of the 12V power supply will not enter pin 5 of the SMS module T3, and then pin 5 of the SMS module T3 will not input a low-level signal and will not send the third SMS message; when any of the fixed frame 1 or the supporting frame 6 is tilted, the mercury switch TN located at the upper end of one or more of the fixed frame 1 or the supporting frame 6 will tilt, and the mercury liquid level of the mercury switch TN will submerge the inner upper end terminal. In this way, the low level of the 12V power supply will enter pin 5 of the SMS module T3, and then pin 5 of the SMS module T3 will input a low-level signal and the SMS module T3 will send the third SMS message stored internally.

[0020] Figure 1 、 2As shown, when debris flow or falling rocks fall on the front end of the barrier steel rope 2, the voltage signal output by pin 3 of the tension sensor T or T1, T2 will enter pins 6, 5, and 4 of the analog signal isolation collector conversion module T4 through the resistor R or R1, R2 for voltage reduction and current limiting. The heavier the debris flow or falling rocks, the higher the signal voltage entering pins 6 or 5, 4 of the analog signal isolation collector conversion module T4. Conversely, the lighter the debris flow or falling rocks, the lower the signal voltage entering pins 6 or 5, 4 of the analog signal isolation collector conversion module T4. When the two laser ranging modules T5 and T6 are powered on, the closer the distance between their transmitter heads and the debris flow or fallen rocks is, the higher the signal voltage output from pins 3 of the two laser ranging modules, T5 and T6, to pins 8 and 7 of the analog signal isolation collector and converter module T4, respectively, becomes. Conversely, the farther the distance between the transmitter heads of the two laser ranging modules T5 and T6 is from the debris flow or fallen rocks, the lower the signal voltage output from pins 3 of the two laser ranging modules, T5 and T6, to pins 8 and 7 of the analog signal isolation collector and converter module T4, respectively, becomes. When the property detection circuit is powered on, if the debris flow or fallen rocks contact the two copper sheets TN, the resistance between the two sheets TN will be relatively low (the output voltage signal will be relatively high). Conversely, if the debris flow is relatively low in moisture, the resistance between the two sheets TN will be relatively high (the output voltage signal will be relatively low). This dynamically changing voltage signal will be input to pin 3 of the analog signal isolation collector and converter module T4. After the analog signal isolation collector conversion module T4 is powered on, it will convert the dynamically changing analog voltage signal input from the 3rd pin of the tension sensor T or T1, T2, the dynamically changing voltage signal input from the two laser ranging modules T5, T6, and the dynamically changing voltage signal input from the property detection circuit into a digital signal, and then transmit the digital signal wirelessly via the 4g module T7. After the application software unit in the smartphone or PC of the remote relevant personnel receives the data, they can view various data intuitively through the screen of the mobile phone or PC (displayed as digital or waveform).

[0021] Figure 1 、 2As shown above, the present invention can install multiple sets from front to back in the area where the river needs to be protected, so as to better protect the river. When mud and rock flows, rock falls, the blocking steel rope breaks, the blocking steel frame (fixed frame or support frame) tilts, etc. occur on site, the relevant remote management personnel can be notified by text message at the first time. After the remote relevant personnel receive the corresponding text message on their mobile phone, they can understand the specific on-site situation at the first time (the text message content will respectively display "mud and rock flows and rock falls", "blocking steel rope breaks", "blocking steel frame is tilted"). Through the Internet of Things technology, the present invention can also send data on the distance between the mud-rock flow and the falling rocks and the river channel to remote management personnel (the larger the number displayed on the mobile phone or PC screen, the farther the laser ranging module and the fixed frame, the blocking steel rope, etc. are from the mud-rock flow or the falling rocks, and vice versa, the closer the distance is; the remote management personnel can thereby understand the distance between the mud-rock flow or the falling rocks and the river channel edge), the approximate number of mud-rock flow and the falling rocks (when the height of the falling rocks or mud-rock flow in front of the lower end of the blocking steel rope is detected to be low, the voltage signal output by the tension sensor T at the lower end displayed on the mobile phone or PC screen is high; when the height of the falling rocks or mud-rock flow in front of the blocking steel rope is detected to be relatively high, the voltage signals output by the tension sensor T at the lower end and the sensor T1 in the middle are high; when the height of the falling rocks or mud-rock flow in front of the blocking steel rope is detected to be very high, the tension sensor T at the lower end and the sensor T2 in the middle are high. The voltage signals output by the force sensor T, the middle sensor T1, and the upper sensor T2 are high; remote personnel can use this to judge the height of the debris flow or rockfall) and property data (the greater the water content of the debris flow, the larger the data displayed on the mobile phone or PC screen, and conversely, the smaller the water content of the debris flow, the smaller the data displayed on the mobile phone or PC screen; remote managers can use this to understand the water content of the debris flow. When the water content is smaller, it tends to be rockfall or landslide. When the water content is higher, it tends to be a debris flow on site). Remote managers can use their smartphones or PCs to intuitively grasp the corresponding data without going to the site, which brings convenience to relevant managers and provides favorable technical support for timely cleaning of the site or maintenance of relevant institutions to ensure stable and reliable equipment and river safety.
