[0002] Flash flood disasters refer to floods, debris flows and landslides caused by rainfall in hilly areas. In recent years, flash flood disasters caused by sudden and localized extreme heavy rainfall in my country have caused a large number of casualties, accounting for an increasing proportion of the total number of deaths in flood disasters, and mass deaths and injuries occur from time to time. Existing flash flood warning equipment, such as the Chinese invention patent with the publication number CN116052380A and the name of a flash flood warning device, can ensure the overall stable operation of the device, protect the internal equipment from damage, and extend the service life. Due to the complex geographical conditions in mountainous areas and the difficulty in laying lines, once the existing warning equipment encounters a large-volume flash flood impact, it may even be overturned by the flash flood before it can issue a warning. Therefore, from the perspective of protecting the internal structure of the warning equipment, once the entire warning equipment is overturned by the flash flood, the internal equipment will naturally be damaged. Therefore, the existing warning equipment is far from meeting the needs of using the equipment in flash flood warning. Therefore, a small watershed flash flood warning device is designed and produced here to solve the above problems. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment, this embodiment provides a small watershed flash flood warning device, including a support base 1, a liquid storage cylinder 14 vertically fixed on the support base 1, and a receiving funnel 15 located at the upper end of the liquid storage cylinder 14, a bracket 2 is fixed to the side wall of the support base 1, a mounting seat 31 is fixed to the top of the bracket 2, a plurality of laser lamp beads 33 are fixed at the center position of the upper end of the mounting seat 31, and a solar panel 32 for powering the laser lamp beads 33 is installed on the upper end surface of the mounting seat 31, such as Figure 1 As shown, the installation position of the mounting base 31 usually needs to exceed the height of the treetops on the hillside, that is, the height of the bracket 2 must meet the height support requirement of the mounting base 31, so as to ensure that the solar panel 32 receives sunlight and performs photoelectric conversion. A secondary battery is built into the support base 1, which stores the electric energy converted by the solar panel 32 through voltage transformation and rectification to meet the power demand of the laser lamp beads 33.

[0025] Furthermore, a liquid guide tube 16 is connected to the bottom wall of the receiving funnel 15, and a plurality of water outlet holes are provided at the bottom end of the side wall of the liquid guide tube 16. A plug hole for slidingly plugging with the liquid guide tube 16 is provided at the upper end of the liquid storage tube 14. A bottom plate 17 is fixed to the bottom end of the liquid guide tube 16, and conductive columns 18 connected by wires are embedded on both sides of the upper end of the bottom plate 17. Docking grooves are provided on both sides of the top wall of the liquid storage tube 14, and a plurality of power connection blocks 110 are embedded in the inner walls of the two docking grooves. The two power connection blocks 110 located in the same horizontal direction in the two docking grooves form a group, and one of the two power connection blocks 110 in the same group is connected in series with one of the Razer lamp beads through a wire, and the other power connection block 110 is connected in series with the solar panel. That is to say, the same group of two power blocks 110 is the connection terminal of a laser lamp bead 33. As long as the two conductive posts 18 connected in series are in contact with the same group of two power blocks 110, the circuit of a single laser lamp bead 33 can be turned on, and the laser lamp bead 33 emits strong light visible to the naked eye. Figure 1 As shown, multiple laser lamp beads 33 are facing the sky. On cloudy days or rainy nights, monitoring personnel can clearly see the light of the laser lamp beads 33 from a long distance.

[0026] According to the monitoring requirements, the above monitoring equipment is set up at different positions on the mountain, that is, the support base 1 is used as the basis for supporting the entire equipment and installed on the hillside. An embedded steel chisel 13 is fixed on the bottom wall of the support base 1, and the embedded steel chisel 13 is embedded in the deep soil of the hillside to assist in stabilizing the entire equipment. A plurality of floating bags 19 are fixedly connected to the bottom wall of the bottom plate 17, and the plurality of floating bags 19 are located in the same vertical plane. Figure 3 As shown, the rain is received by the receiving funnel 15 and enters the liquid storage cylinder 14 through the water outlet hole of the liquid guide tube 16. Figure 4 As shown, as the liquid level continues to rise, the float 19 generates corresponding buoyancy, which lifts the receiving funnel 15, the liquid guide tube 16, the bottom plate 17 and the conductive column 18 upward. The two conductive columns 18 follow the liquid guide tube 16 and are inserted into the corresponding docking grooves respectively, contacting each power connection block 110 from bottom to top, and conducting the circuit of each laser lamp bead 33 to form a multi-level control and early warning system. Through real-time monitoring of rainfall, a multi-level control and early warning system is set up, and the number of laser lamp beads 33 flashes is used to assist the staff in determining the amount of rainfall in the area. That is to say, at the same monitoring position, the more flashes of the laser lamp beads 33, the greater the rainfall, and the greater the possibility of flash floods, so as to assist the staff in observing the dynamics of the hillside from a distance, and can technically assist the monitoring personnel in grasping the speed of soil sliding, so as to evacuate the downstream residents in time. The problem of signal shielding in the existing technology that most mountainous areas use remote signal transmission modules for monitoring is solved. The overall structure is simple, a large number of intelligent devices are not used, and the cost is low.

[0027] It should be noted that both the liquid conduit 16 and the plug hole are N-sided structures, where N is not less than four, and preferably four, in order to prevent the liquid conduit 16 from rotating in the plug hole, causing the conductive column 18 to be misaligned with the docking slot, thus affecting the conduction of the laser lamp bead 33 circuit.

[0028] In addition, when the conductive column 18 is inserted into the docking groove and contacts the power connection block 110, in order to increase the contact force and ensure normal circuit connection, the power connection block 110 is set to a hollow elliptical structure, and a recessed portion for accommodating the power connection block 110 is opened on the inner wall of the docking groove, such as Figure 5 As shown, after the conductive column 18 is inserted into the docking groove, it contacts the side wall of the power connection block 110, which will squeeze the hollow elliptical power connection block 110, causing it to deform into the recessed portion and generate rebound potential energy to ensure close contact.

[0029] After the rain stops, the water in the liquid storage cylinder 14 needs to flow out. For this purpose, a drainage hole is provided at the bottom of the side wall of the liquid storage cylinder 14, and the rainwater in the liquid storage cylinder 14 is drained through the drainage hole. However, it is required to be limited that the diameter of the drainage hole is less than 5-10 times the diameter of the water outlet hole. That is, the diameter of the water outlet hole is much larger than the diameter of the drainage hole. In this way, when it rains, the rainwater entering the liquid storage cylinder 14 will flow out faster than the rainwater, so as to ensure that there is enough rainwater in the liquid storage cylinder 14 to assist the monitoring operation, but at the same time, after the rain stops, the rainwater in the liquid storage cylinder 14 will be drained for subsequent use.

[0030] Further, such as Figure 1 As shown, it also includes a support mechanism arranged on the side of the support base 1 for straightening the support base 1. The support mechanism is used to assist in supporting the side of the support base 1 with a lower terrain to prevent the support base 1 from tilting.

[0031] Specifically, a plurality of limit clamping strips 11 are fixed to the side wall of the support base 1, and the limit clamping strips 11 are arranged in a vertical structure. A plurality of clamping columns 12 are fixed to the side wall of the limit clamping strip 11. The support mechanism includes a U-shaped block 21 with a clamping hole, a support rod 3 fixed to the side wall of the U-shaped block 21, and a foot 22 fixed to the bottom end of the support rod 3. Figure 2 As shown, the U-shaped block 21 is tightly connected to the corresponding clamping column 12 on the limiting clamping strip 11 on the relatively lower side of the support base 1 through the clamping hole, and the support rod 3 and the base foot 22 at its bottom end play an auxiliary support role on the side of the support base 1 to prevent the overall equipment from tilting or shaking due to unstable center of gravity.

[0032] Furthermore, the foot 22 is a spherical structure, and the outer wall of the foot 22 is provided with a plurality of protruding teeth, and the protruding teeth are provided to prevent the foot 22 from sliding sideways. Alternatively, a through hole is provided in the foot 22, and a positioning rod 23 is inserted into the through hole, and the bottom end of the positioning rod 23 passes through the through hole and is nailed into the deep soil of the hillside, which also prevents the foot 22 from sliding sideways.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
