DETAILED DESCRIPTION

[0029] The utility model is further described below in conjunction with the accompanying drawings.

[0030] according to Figure 1 , Figure 2 As shown, an embodiment of the present application proposes a debris flow direction prediction device, including a prediction device body 3, a protective structure is arranged on the top of the prediction device body 3; the protective structure includes a connecting seat 4 rotatably arranged on the top of the prediction device body 3, the connecting seat 4 is fixedly provided with a wind direction sensing drive component 6, the connecting seat 4 is connected to a shielding component 5 for shielding one side of the prediction device body 3, and in a working state, the wind direction sensing drive component 6 senses the wind direction under the action of wind force and drives the connecting seat 4 to rotate, so that the shielding component 5 is on the windward side of the prediction device body 3, and the prediction device body 3 includes a fixed seat 1 that can be installed on a mountain, specifically, the fixed seat 1 can be a fixed cone with multiple spikes at the lower end, which can penetrate into the mountain so that the entire device remains fixed on the ground, and the upper end of the fixed seat 1 is connected to a support column 2, which can stably support the prediction device body 3.

[0031] It should be noted that the above-mentioned prediction device body 3 is an existing debris flow and flood monitoring station, and a mounting plate is arranged on the top of the prediction device. The above-mentioned mounting plate is rotatably connected to the connecting seat 4 by a bearing connection, so that the long-term rotation between the connecting seat 4 and the mounting plate is not easy to cause wear. At the same time, the above-mentioned wind direction sensing drive component 6 can be an existing wind direction sensor connected to the controller, and the controller is connected to the servo motor arranged on the connecting seat 4. The driving end of the servo motor can control the rotation of the connecting seat 4. The wind direction sensor converts the sensed physical signal of the wind direction into an electrical signal and sends it to the control circuit of the servo motor through the controller, so that the servo motor controls the above-mentioned connecting seat 4 to rotate until the shielding component 5 is on the windward side, thereby realizing the protective effect of the shielding component 5 on the prediction device body 3. In another embodiment, in order to reduce costs and simplify the structure, the above-mentioned wind direction sensing drive component 6 includes The invention also comprises a wind vane component connected to the connecting seat 4, wherein the wind vane component is provided with a pointing end 61 away from the connecting seat, and the shielding component 5 is connected to a side of the connecting seat 4 away from the pointing end 61. In a working state, the wind vane component rotates under the action of wind force and drives the shielding component 5 to be on the windward side of the prediction device body 3, and the wind vane component is provided with a pointing arrow, which points to the wind direction, plays a marking effect, and makes the shielding component 5 rotate to the windward side. Moreover, the wind vane component refers to the existing wind vane. The specific principle is that the wind receiving area of ​​one end is larger than that of the other end. If both ends are affected by wind, the end with a larger wind receiving area will be pushed back by the wind, so that the end with a smaller wind receiving area moves to the source of the wind. In this embodiment, the direction of the arrow at the pointing end 61 indicates the direction of the wind with a larger wind receiving area, and the shielding component provided on the connecting seat 4 away from the pointing end 61 is on the leeward side, thereby achieving a protective effect.

[0032] according to Figure 3-Figure 7 As shown, with regard to the installation structure of the connecting seat 4 and the prediction device body 3, a rotating column 10 is provided at the lower end of the connecting seat 4, and the rotating column 10 is rotatably connected to the top of the prediction device body 3. The rotating column 10 can ensure that there is a certain height difference between the connecting disk and the prediction device body 3. When the connecting seat 4 rotates relatively, no mutual obstruction or friction will occur, thereby ensuring that the connection part is not damaged and improving stability and service life.

[0033] With regard to the specific structure of the above-mentioned shielding component 5, the above-mentioned shielding component 5 includes a plurality of ribs 51 movably arranged on the side of the above-mentioned connecting seat 4 away from the above-mentioned pointing end 61, and a flexible shielding layer 52 is connected between two adjacent ribs 51. The above-mentioned connecting seat 4 is also provided with a wind receiving piece 7, and the above-mentioned wind receiving piece 7 is provided with a wind blocking surface 72, and a transmission component 8 is arranged between the above-mentioned wind receiving piece 7 and the above-mentioned ribs 51. The above-mentioned wind receiving piece 7 is driven by the above-mentioned transmission component 8 under the action of wind force to drive the plurality of the above-mentioned ribs 51 to move relatively away from and stretch the above-mentioned flexible shielding layer 52. That is to say, the wind blocking surface 72 of the wind receiving piece 7 generates displacement or force under the action of wind force, thereby driving the above-mentioned transmission component 8 to act on the plurality of ribs 51 to cause relative displacement away, thereby realizing the effect of opening the flexible shielding layer 52.

[0034] Specifically, the specific structure of the transmission assembly 8 can be a plurality of guide rods, and the ribs 51 can achieve horizontal displacement on one side of the connecting block 54 through a slide groove or other connection methods. The plurality of guide rods correspond to and are connected to the plurality of ribs 51 one by one. The moving force generated by the wind receiving member 7 drives the plurality of ribs 51 to move through the existing driving mechanism, and two adjacent ribs 51 have a movement trend away from each other. The ribs 51 act on the flexible shielding layer 52, so that the flexible shielding layer 52 is expanded to achieve a shielding effect. In another preferred embodiment, an arc-shaped guide rod 53 is provided on the side of the connecting seat 4 away from the pointing end 61. The outer wall of the arc-shaped guide rod 53 is slidably sleeved with a plurality of connecting blocks 54, and the plurality of connecting blocks 54 correspond one to one with the plurality of ribs 51. One end of the rib 51 close to the connecting seat 4 is connected to the connecting block 54, and a tension spring 55 is connected between two adjacent connecting blocks 54. The driving end of the transmission assembly 8 is respectively connected to the two connecting blocks 54 at both ends, that is, the rib 51 slides on the arc-shaped guide rod 53 through the connecting blocks 54, and the displacement effect is more stable. In addition, the arrangement of the arc-shaped guide rod 53 enables the rib 51 and the flexible shielding layer 52 to form an arc-shaped umbrella-shaped shielding surface after stretching, and the shielding area is larger, thereby improving the protection effect.

[0035] Moreover, the arrangement of the tension spring 55 allows the tension spring 55 to contract when the wind is relatively small or there is no wind, so that two adjacent connecting blocks 54 are brought closer together, thereby reducing the area of ​​the shielding layer formed by the ribs 51 and the flexible shielding material, thereby reducing the impact on the operation of the prediction device body 3. The arrangement of the tension spring 55 can also ensure that all connecting blocks 54 can be stretched synchronously by acting only on the two connecting blocks 54 at both ends, thereby reducing the distribution area of ​​the transmission assembly 8 and reducing the difficulty of processing.

[0036] The flexible shielding layer 52 is generally a shielding cloth formed of tensile fibers, which has good impact resistance and a small mass, and thus has little hindrance to the normal rotation of the connecting seat 4 .

[0037] In order to further improve the stability of the movement of the umbrella rib 51, the side wall of the above-mentioned connecting seat 4 away from the above-mentioned pointing end 61 is provided with an arc groove 41 adapted to the shape of the above-mentioned arc guide rod 53, the above-mentioned arc guide rod 53 is located in the above-mentioned arc groove 41, the connecting block 54 moves in the arc groove 41, and the arc groove 41 is only provided on one side of the connecting seat 4, which can limit the position of the connecting block 54 and the umbrella rib 51 on one side of the connecting seat 4, ensuring that the umbrella rib 51 is extended and retracted within the area on one side of the connecting seat 4, and preventing the shielding layer formed by the umbrella rib 51 and the flexible shielding material from arbitrarily displacing on the connecting seat 4 and causing instability in the shielding position.

[0038] With regard to the connection structure between the wind receiving member 7 and the transmission assembly 8, specifically, the connection seat 4 is provided with a guide groove 81 extending in the direction of the pointing end 61, a guide rod 82 is provided in the guide groove 81, a slider 83 is slidably provided in the guide groove 81, the slider 83 is slidably sleeved on the guide rod 82, a return spring 84 is sleeved on the side of the guide rod 82 close to the rib 51, the two ends of the return spring 84 are respectively connected to the slider 83 and the inner wall of the guide groove 81, the upper end of the slider 83 is connected to the wind receiving member 7, the transmission assembly 8 includes a driving block 85 connected to the lower end of the slider 83, the driving block 85 is connected to two pull ropes 86, and the two pull ropes 86 are respectively connected to the two ends. Two connecting blocks 54, that is, the wind-blocking surface 72 of the wind-receiving member 7 moves under the action of wind force and drives the slider 83 to slide on the guide rod 82, and at the same time the slider 83 compresses the return spring 84 in the guide groove 81. Since the wind-blocking surface 72 is on the same side as the shielding component 5, the wind-receiving member 7 moves away from the shielding component 5, and the driving block 85 pulls the stretching to move away from the ribs 51 and the connecting blocks 54, so that the two connecting blocks 54 at both ends are stretched outward and moved, and through the action of multiple tension springs 55, the adjacent ribs 51 are stretched in both directions, so that the flexible shielding layer 52 is stretched open, and a stable shielding layer is formed on the windward side of the prediction device body 3 to ensure a stable shielding effect.

[0039] Regarding the above-mentioned wind receiving part 7, in a specific implementation manner, in order to improve the force stability of the wind blocking surface 72, the above-mentioned wind receiving part 7 includes a box body 71 with a single-sided opening, and the opening of the above-mentioned box body 71 is located on one side of the above-mentioned wind blocking surface 72. The shape of the above-mentioned box body 71 can be a cube or a polygon, and the opening surface of the box body 71 is the wind blocking surface 72, and the opening is in the same direction as the shielding component 5, so that when the opening of the box body 71 is against the wind, wind is poured into the box body 71, forming a stabilizing effect on the box body 71.

[0040] In addition, in actual work, there is no wind or the wind is weak in most cases, and the prediction device body 3 needs to detect and predict various directions. It is possible that when detecting the direction where the shielding component 5 is located, the shielding component 5 may affect the prediction accuracy. In order to reduce the risk of the above problem, according to Figure 8-Figure 10 As shown, an adjusting component 9 for driving the connecting seat 4 to rotate is also provided at the top of the prediction device body 3. That is to say, in a windless or low wind environment, the adjusting component 9 can be driven to adjust the orientation of the connecting seat 4 to reduce the impact.

[0041] Furthermore, the adjustment component 9 may be a manual adjustment structure, or for the convenience of operation, a mechanical structure controlled by a remote wired or wireless electrical signal, with an electronic drive structure capable of driving the connection seat 4 to rotate.

[0042] Specifically, the adjustment component 9 includes a first motor 91 arranged on the prediction device body 3, the first motor 91 is provided with a connecting arm 92, a second motor 94 is provided at one end of the connecting arm 92 away from the first motor 91, a driving end of the second motor 94 is connected with a driving gear 93, and the connecting seat 4 is connected with a driven gear 95 for driving the connecting seat 4 to rotate. In the working state, the driving gear 93 and the driven gear 95 are meshed. In the case of no wind or weak wind, when the shielding component 5 affects the prediction work in a certain direction, the first motor 91 is rotated by remote control, so that the connecting arm 92 drives the driving gear 93 and the second motor 94 to rotate, so that the driving gear 93 rotates along the axis of the driving shaft of the first motor 91 to the position where the driven gear 95 engages, and then the second motor 94 is started to run forward and reverse, so as to adjust the rotation of the connecting seat 4 relative to the prediction device body 3 and adjust the reasonable direction. When there is strong wind, the first motor 91 is controlled to control the connecting arm 92 to reverse, so that the driving gear 93 and the driven gear 95 are disengaged, so that the rotation process of the connecting seat 4 sensing the drive component 6 with the wind direction is not affected.

[0043] Moreover, the first motor 91 and the second motor 94 are both servo motors, which can ensure stable and accurate forward and reverse rotation and emergency stop brake action, thereby ensuring stable and accurate adjustment effect of the adjustment component 9.

[0044] In summary, the embodiment of the present application proposes a debris flow direction prediction device, including a prediction device body 3, a protective structure is arranged on the top of the prediction device body 3; the protective structure includes a connecting seat 4 rotatably arranged on the top of the prediction device body 3, a wind direction sensing drive component 6 is fixedly arranged on the connecting seat 4, and a shielding component 5 for shielding one side of the prediction device body 3 is connected to the end of the connecting seat 4 away from the wind direction sensing drive component 6.
