[0049] Example:

[0050] As a preferred embodiment, Figures 1 to 9 As shown,

[0051] A semi-submersible flash flood warning device based on GIS technology, comprising a GIS signal transmitting unit 1, one end of which is provided with a semi-submersible flash flood warning monitoring unit 2, and the GIS signal transmitting unit 1 is electrically connected to the semi-submersible flash flood warning monitoring unit 2 through a wire;

[0052] The semi-submersible flash flood warning monitoring unit 2 includes a semi-submersible component 21, which is a hollow cylinder with openings at the top and bottom ends. The semi-submersible component 21 is provided with a hollow interlayer. A flash flood warning monitoring component 22 is provided on the semi-submersible component 21, and the flash flood warning monitoring component 22 is electrically connected to the GIS signal transmitting unit 1 through a wire.

[0053] The flash flood warning monitoring component 22 includes a first insulating plate 221, which is fixedly arranged on the side of the inner ring of the semi-submersible component 21. A metal joint group 222 is arranged on one side of the first insulating plate 221. An elastic reset component 223 is also arranged on the first insulating plate 221. The elastic reset component 223 and the metal joint group 222 are located on the same side. The other end of the elastic reset component 223 is connected to a second insulating plate 224, which is slidingly connected to the side of the inner ring of the semi-submersible component 21. A metal contact 225 is arranged on one side of the second insulating plate 224, and an elastic waterproof membrane 212 is arranged on the other side. The metal contact 225 is electrically connected to the metal joint group 222, and the metal joint group 222 is electrically connected to the GIS signal transmitting unit 1 through a wire.

[0054] In order to explain the present invention more clearly and specifically, in this embodiment, by setting up a GIS signal transmitting unit 1, a semi-submersible flash flood early warning monitoring unit 2 and other structures, the semi-submersible flash flood early warning monitoring unit 2 is used to monitor and warn flash floods, and the monitoring and early warning information is sent out through the GIS signal transmitting unit 1, which solves the technical defect of the prior art that flash floods cannot be automatically monitored and warned, and realizes the technology that can be automatically started when a flash flood breaks out.

[0055] In order to better illustrate the present invention, in this embodiment, the semi-submersible flash flood warning monitoring unit 2 is provided with a semi-submersible component 21, a flash flood warning monitoring component 22 and other structures, so that the present invention has the function of real-time warning of flash floods.

[0056] In order to further clarify and clearly explain the present invention, as a preferred embodiment, the working process of the flash flood warning monitoring component 22 is as follows: Figure 3 As shown, assuming that the present invention is impacted by a flood and the elastic waterproof membrane 212 is squeezed, the squeezing force borne by the elastic waterproof membrane 212 is transmitted to the second insulating plate 224, and the second insulating plate 224 moves toward the end of the first insulating plate 221. The metal contact 225 on the second insulating plate 224 contacts the metal joint on the first insulating plate 221 and forms a circuit structure in a power-on state. At this time, the elastic reset component 223 arranged between the first insulating plate 221 and the second insulating plate 224 is in a compressed state, and the GIS signal transmitting unit 1 arranged in the flash flood warning component will transmit the flash flood information detected in real time. When the flash flood recedes, the pressure borne by the compression reset component disappears, and the compression reset component in the energy storage state will eject the second insulating plate 224, thereby disconnecting the power supply 14 between the metal contact 225 and the metal joint.

[0057] It should be particularly and clearly stated that, as a preferred implementation, in this embodiment, the elastic reset component 223 can be one or more of the materials such as a reset spring and a reset rubber gasket.

[0058] In order to better realize the present invention, as a further description of the above technical scheme, the semi-submersible component 21 includes a counterweight bin 211, which is a hollow cylinder with openings at the top and bottom ends, and is a hollow sandwich structure. The bottom end of the hollow sandwich of the counterweight bin 211 is detachably connected with a disc, and the hollow sandwich of the counterweight bin 211 is filled with counterweights. The elastic waterproof membrane 212 is arranged in the inner ring of the counterweight bin 211, and the elastic waterproof membrane 212 protrudes toward the second insulating plate 224. The other end of the counterweight bin 211 is seamlessly connected to the GIS signal transmitting unit 1, and a detachable anchoring component 213 is arranged on the axial side of the counterweight bin 211, and the detachable anchoring component 213 anchors the counterweight bin 211 to the ground.

[0059] In order to explain the present invention more clearly and specifically, as a preferred implementation mode, in this embodiment, the semi-submersible component 21 is provided with a counterweight bin 211 structure which is a hollow cylinder with openings at the top and bottom and a hollow interlayer, and the second insulating plate 224 and the elastic waterproof membrane 212 in the flash flood warning component are both installed in the hollow cylinder of the counterweight bin 211. Through this scheme, the structure of the present invention is made more compact, and the practicality of the present invention is effectively improved.

[0060] As a further description of the above technical solution, the detachable anchoring component 213 includes an anchor rod 2131, and the anchor rod 2131 has an expansion shell end and a connecting end. The expansion shell end and the rod body of the anchor rod 2131 are anchored in the geological body, and a support plate 2132 is arranged on the connecting end of the anchor rod 2131. A plurality of vertical spur racks 2133 are arranged in an annular array on the support plate 2132, and circular gears 2134 are meshed on the vertical spur racks 2133. The circular gears 2134 are rotatably set on a U-shaped ring 2135, and the U-shaped ring 2135 is fixedly set on the outer surface of the counterweight bin 211.

[0061] In order to explain the present invention more clearly and explicitly, as a preferred embodiment, in this embodiment, the working principle of the detachable anchoring component 213 is as follows: when there is no flash flood in the area where the present invention is used, the present structure carrying the GIS signal transmitting unit 1 is set on the anchoring component, and the anchoring component is anchored in the geological body. When a flash flood occurs in the area where the present invention is used, the elastic waterproof membrane 212 in the flash flood early warning monitoring device is squeezed by the flood. At this time, the device is in a semi-submerged state, the water level rises, and the device follows the water level to raise the altitude. At this time, the circular gear 2134 moves vertically upward along the spur rack and finally falls off the spur rack, which finally enables the present invention to drift with the flood.

[0062] As a further description of the above technical solution, the metal joint group 222 includes at least two metal joints, the metal joints are insulated from each other, and the metal joints are all connected with wires.

[0063] As a further description of the above technical solution, the GIS signal transmitting unit 1 includes a supporting protective structure 11, the outer side of the supporting protective structure 11 is sealed with a waterproof insulating layer 12, and a signal transmitter 13 and a power supply 14 are arranged inside the supporting protective structure 11. The signal transmitter 13, the power supply 14, the metal joint group 222 and the metal contact 225 are electrically connected in sequence through wires to form a passage structure.

[0064] In order to explain the present invention more clearly and explicitly, as a preferred implementation mode, in this embodiment, the working process of the GIS signal transmitting unit is as follows: first, the flash flood warning monitoring device is impacted by the flood and squeezes the elastic waterproof component, the elastic waterproof component squeezes the second insulating plate 224 and makes the metal contact 225 provided on the second insulating plate 224 electrically connected to the metal connector, and the GIS signal transmitter 13 detects and obtains the flood information at the altitude and transmits it to the rear server and stores it.

[0065] As a further description of the above technical solution, the supporting and protective structure 11 includes a vertical supporting tube 111, a plurality of disc supports 112 are arranged on the outer wall of the vertical supporting tube 111, a waterproof insulating layer 12 is arranged on the outer side of the disc support 112, and a signal transmitter 13 and a power supply 14 are arranged on the disc support 112.

[0066] In order to explain the present invention more clearly and specifically, as a preferred implementation mode, in this embodiment, the supporting and protective structure is provided with a disc support 112, so that when the new type is hit by foreign objects in a flood, the device will not malfunction due to deformation.

[0067] In order to better illustrate the present invention, as a preferred implementation mode, in this embodiment, by providing a waterproof insulating layer 12, all components of the present invention can work normally during use, thereby further improving the practicality of the present invention.

[0068] In order to better realize the present invention, as a preferred embodiment, Figures 1 to 5 As shown, the workflow of the present invention is: first, select a monitoring section and measure and determine each installation position of the present invention at a unified monitoring section, anchor the anchor rod 2131 in the geological body of each installation position, install the present invention on the anchor rod 2131, put the balancing material into the balancing weight bin 211, and complete the installation.

[0069] In order to explain the present invention more clearly and explicitly, as a preferred implementation mode, the present invention is further explained in this embodiment. When the flood reaches the large monitoring section, the device at the lowest altitude is first submerged. The device switch is closed under the action of external water pressure. At this time, the device at this location transmits a position signal to the server to realize the flood warning at this altitude of the section. When the flood volume is large enough, the device will drift with the water flow. The device switch is always in a closed state under the action of external water pressure. The GIS transmitter in the device sends the real-time position to the server and stores it through the BDS (BeiDou Navigation Satellite System) or GPS (GlobalPositioning System) device. The platform calculates the flow rate of the flood by obtaining the position and time interval of the device, and realizes the tracking of the development of the flood.

[0070] Through the above scheme, the flash flood warning device can be self-starting when encountering a flash flood. At the same time, by setting an anchor component and slidingly connecting a semi-submersible flash flood warning unit equipped with a GIS signal transmitting unit to the anchor component, the flash flood warning device can drift with the flash flood when encountering a flash flood, thereby realizing the technology of monitoring the flash flood flow and direction.

[0071] A flash flood warning method for a semi-submersible flash flood warning device based on GIS technology, wherein a semi-submersible flash flood warning device group is vertically installed as a unit in the same section of a monitoring area, the monitoring section of the semi-submersible flash flood warning device group intersects with the central axis of the water flow direction of the detection area, the semi-submersible flash flood warning device group includes at least two semi-submersible flash flood warning devices for simultaneously warning and monitoring flash floods, the semi-submersible flash flood warning devices are installed at different altitudes in the same monitoring section, and the semi-submersible flash flood warning devices immersed in the flash flood drift with the flash flood;

[0072] The specific steps are as follows:

[0073] S1. Collect and analyze regional geological features and precipitation information, determine several sections to be monitored based on the analysis results, and name and number each section to be monitored in sequence to form a naming and numbering group. At the same time, determine the accurate monitoring positions at different altitudes on each section to be monitored based on the terrain conditions of the same section and the local precipitation conditions;

[0074] S2, setting a data transmission time interval of the same length for each semi-submersible flash flood warning device to be installed, and then installing a semi-submersible flash flood warning device at each monitoring position, and placing it in a waiting state;

[0075] S3, the semi-submersible flash flood warning device that first contacts the flash flood enters the working state under the combined effect of water pressure and its own counterweight, and the GIS signal transmitting unit 1 sends the GIS information of the initial position to the back-end database; as the water level rises, the semi-submersible flash flood warning device changes from a fixed state to an active state and drifts with the flood, and the drifting semi-submersible flash flood warning device sends the real-time GIS information of its location to the back-end database at regular intervals;

[0076] S4. The back-end database calculates the size of the flash flood flow based on the real-time GIS information regularly transmitted by the semi-submersible flash flood warning device and distributes the calculation results to various display terminals.

[0077] In order to explain this method more clearly and explicitly, in this embodiment, Figure 6 As shown in the figure, firstly, the regional geological and geomorphological information is collected by using GIS equipment, and at the same time, several sections to be monitored are analyzed and determined according to the longitude and latitude of the area and the precipitation data within the period. After the monitoring sections are determined, each section to be monitored is named and numbered in sequence immediately. Next, the accurate monitoring positions at different altitudes are determined on each section to be monitored according to the terrain conditions and local precipitation conditions of the same section, and then the data transmission time interval of the same length is set for each semi-submersible flash flood warning device to be installed. After the time setting is completed, the semi-submersible flash flood warning device is installed at each monitoring position, and each semi-submersible monitoring device is in a waiting state. Assuming that the semi-submersible flash flood warning device has been installed When a flash flood breaks out in the monitoring area of ​​the warning device, the semi-submersible flash flood warning device that first contacts the flash flood enters the working state under the combined effect of water pressure and its own counterweight, and the GIS signal transmitting unit 1 sends the GIS information of the initial position to the back-end database; as the water level rises, the semi-submersible flash flood warning device changes from a fixed state to an active state and drifts with the flood, and the drifting semi-submersible flash flood warning device periodically sends the real-time GIS information of its location to the back-end database, and after receiving the data information sent back by the semi-submersible flash flood warning device, the back-end database calculates the flash flood flow size according to the real-time GIS information regularly transmitted by the semi-submersible flash flood warning device and distributes the calculation results to various display terminals.

[0078] In order to better illustrate this method, as a further optimization of the above technical solution, Figure 7 As shown, step S2 has the following steps:

[0079] S21, firstly, set the same data transmission time interval on each GIS signal transmitting unit 1 to be installed and test each device to ensure that it can work normally;

[0080] S22, vertically drilling holes at the set monitoring positions and pre-embedding anchor rods 2131, while making the anchor rods 2131 in a pull-out resistant state;

[0081] S23, installing the semi-submersible flash flood warning monitoring unit 2 equipped with the GIS signal transmitting unit 1 on the anchor rod 2131, and detecting whether the semi-submersible flash flood warning monitoring unit 2 can slide up and down along the vertical spur rack 2133;

[0082] S24. Calculate the required buoyancy value of each semi-submersible flash flood warning monitoring unit 2 in a semi-submersible drifting state according to the precipitation information, determine how many counterweights to set according to the required buoyancy value, and place the counterweights in the counterweight bins 211 of each semi-submersible flash flood warning monitoring unit 2.

[0083] It needs to be particularly clarified and explained that, as a preferred implementation mode, in this embodiment, after the installation of the anchor rod 2131 is completed, the anchoring of the anchor rod 2131 needs to be subjected to a pull-out test to ensure that the anchor rod 2131 can work normally. After the pull-out test of the anchor rod 2131, the semi-submersible flash flood warning device is installed on the anchor rod 2131, and a counterweight with a calculated mass is placed in the counterweight bin 211 of the semi-submersible flash flood warning device. After completing the above steps, the semi-submersible flash flood warning device with the counterweight placed is pulled upward, and the semi-submersible flash flood warning device is subjected to a semi-submersible working status detection technology.

[0084] In order to explain this method more clearly and explicitly, as a further optimization of the above technical solution, in this embodiment, Figure 8 As shown, step S3 has the following steps:

[0085] S31, the buoyancy generated by the rising flash flood water level triggers the elastic waterproof membrane 212 of the semi-submersible flash flood warning device, the elastic waterproof membrane 212 causes the second insulating plate 224 to move toward the end of the first insulating plate 221 and puts the circuit in a powered-on state, and the GIS signal transmitter 13 in the powered-on state sends the real-time GIS information of the initial state to the back-end database;

[0086] S32, the water level continues to rise, the semi-submersible flash flood warning device changes from a fixed state to a semi-submersible state, and floats up along the anchoring component along with the rising water level;

[0087] S33. The semi - submersible mountain flood warning device detaches from the anchoring component and enters a drifting state. The semi - submersible mountain flood warning device in drifting periodically sends real - time GIS information of its location to the backend database.

[0088] To more clearly and explicitly elaborate on this method, as a preferred embodiment, in this example, when the semi - submersible mountain flood warning device is soaked by the mountain flood and in the initial working state, it sends the GIS information in the initial state to the backend database through the GIS signal transmitting unit 1. When the semi - submersible mountain flood warning device slides off the anchor rod 2131 under the action of the flood buoyancy and enters the drift state, the semi - submersible mountain flood warning device periodically sends the real - time GIS information of its location. Through the comparison and calculation of the GIS information, the mountain flood flow rate can be obtained, and the mountain flood flow direction can be obtained according to the positional relationship shown by the GIS information of the location.

[0089] It needs to be specifically clarified and stated that, as a preferred embodiment, in this example, as Fig. 9 shown, the conditions in the figure are as follows: F represents the drainage weight of the device, and △H represents the height of the liquid level above the top of the fixed device (the bottom position of the monitoring device). The external force required to trigger the device switch is F1, and the self - weight of the device is G.

[0090] The start - up and the process of detaching from the anchor rod 2131 of the semi - submersible mountain flood warning device are as follows: The mountain flood water level rises to the bottom of the semi - submersible mountain flood warning device and contacts the elastic waterproof membrane 212. As the water level rises, the buoyancy generated by the mountain flood squeezes the elastic waterproof membrane 212. As the water level continues to rise, when the liquid level height reaches △H1, the buoyancy of the entire device is F1, the test trigger device switch is activated, and a warning is issued. At this time, F < G, that is, the buoyancy generated by the flood is transmitted through the elastic waterproof membrane 212 to the second insulating plate 224, and the metal contact 225 arranged on the second insulating plate 224 contacts the metal joint arranged on the first insulating plate 221. At this time, the semi - submersible mountain flood warning device is in the working state and sends the GIS information in the initial state to the backend database; Next, the water level continues to rise. When the liquid level height reaches △H2, the drainage weight of the device is equal to the self - weight of the device, that is, F = G. At this time, the device is just at the floating critical state; When the liquid level height reaches △H3, the device floats and detaches from the fixed device. At this time, the device is at the critical point of the drifting state, that is, the semi - submersible mountain flood warning device moves upward along with the mountain flood water level line and finally detaches from the vertical straight rack 2133 fixed to the anchor rod 2131, thus realizing the technology of drifting along with the flood.

[0091] Through the above - mentioned solution, the technology of real - time active warning of mountain floods and real - time monitoring of mountain flood flow rate, flow direction, etc. is realized by means of the semi - submersible mountain flood warning device drifting along with the mountain flood.

[0092] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
