DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Reference Figure 1-Figure 4 The present invention provides a high-speed water curtain anti-abrasion device for debris flow drainage channel, comprising:

[0026] The water curtain pipe assembly 3 includes a plurality of high-speed water flow nozzles 6, which are embedded in the bottom plate of the debris flow drainage channel 1, and the water outlet ends of the high-speed water flow nozzles 6 are arranged flush with the bottom plate of the debris flow drainage channel 1. The plurality of high-speed water flow nozzles 6 are used to form a water curtain between the bottom plate of the debris flow drainage channel 1 and the debris flow 2;

[0027] The self-starting component includes a liquid level monitoring component arranged in the debris flow guide groove 1, the liquid level monitoring component is used to monitor the mud level of the debris fluid 2, and also includes an intelligent controller 5. When the liquid level monitoring component contacts the debris fluid 2, the intelligent controller 5 controls several high-speed water flow nozzles 6 to spray water.

[0028] Several high-speed water flow nozzles 6 are installed together when the debris flow drainage channel 1 is constructed to form a whole. When needed, several high-speed water flow nozzles 6 spray water at the same time to form a water curtain, isolating the debris fluid 2 and the bottom plate of the debris flow drainage channel 1, weakening the abrasive effect of the debris fluid 2 on the bottom plate concrete of the debris flow drainage channel 1, and increasing the service life of the debris flow drainage channel 1 structure; the main function of the liquid level height monitoring component is to monitor whether the height of the debris fluid 2 in the debris flow drainage channel 1 reaches the limit, and transmit the monitoring signal to the intelligent controller 5 when the debris fluid 2 reaches the height limit; the main function of the intelligent controller 5 is to control the several high-speed water flow nozzles 6 to spray water to form a water curtain. On the whole, the present invention installs a number of high-speed water flow nozzles together in the bottom plate of the debris flow drainage trough during the construction of the debris flow drainage trough, and sets a liquid level monitoring device. After the mud level of the debris fluid in the debris flow drainage trough increases to a certain level, the present invention automatically starts a number of high-speed water flow nozzles to spray water to form a water curtain between the debris fluid and the bottom plate of the debris flow drainage trough. The water curtain is used to support the debris fluid, weakening the contact between the debris fluid in a fast-flowing state and the bottom plate of the debris flow drainage trough, significantly reducing the abrasive effect of the debris flow on the concrete material of the bottom plate of the debris flow drainage trough, and helping to increase the service life of the debris flow drainage trough structure.

[0029] To further optimize the solution, the high-speed water flow nozzle 6 is set to a truncated cone shape, the large diameter end of the high-speed water flow nozzle 6 faces upward and the large diameter end of the high-speed water flow nozzle 6 is flush with the bottom surface of the debris flow guide trough 1, the large diameter end of the high-speed water flow nozzle 6 is the water outlet end, and the small diameter end of the high-speed water flow nozzle 6 is connected to the water inlet branch pipe 9.

[0030] like Figure 1 and Figure 2 As shown, the water inlet branch pipe 9 and the high-speed water flow nozzle 6 are embedded together in the bottom plate of the debris flow drainage channel 1, so that the high-speed water flow nozzle 6 is firmly fixed.

[0031] To further optimize the solution, when the upper surface of the bottom plate of the debris flow drainage guide trough 1 is arc-shaped, the end faces of the large diameter ends of several high-speed water flow nozzles 6 are arranged in accordance with the bottom plate of the debris flow drainage guide trough 1 to ensure that the large diameter ends of the high-speed water flow nozzles 6 are flush with the bottom plate of the debris flow drainage guide trough 1, avoiding the formation of a step surface and reducing the scouring damage of the debris flow to the debris flow drainage guide trough 1.

[0032] According to a further optimized solution, a nozzle cone top protection net 7 is fixedly connected to the inner side of the large diameter end of the high-speed water flow nozzle 6, and an opening is provided in the middle of the nozzle cone top protection net 7.

[0033] like Figure 2 As shown, in this embodiment, the nozzle cone top protection net 7 can be welded by steel bars.

[0034] According to a further optimized solution, the height of the high-speed water flow nozzle 6 is between 11 cm and 13 cm, and the diameter of the large-diameter end of the high-speed water flow nozzle 6 is between 4 cm and 6 cm.

[0035] like Figure 2 As shown, the height of the high-speed water flow nozzle 6 is h. In this embodiment, the height h is 12 cm. At the same time, the diameter of the large diameter end of the high-speed water flow nozzle 6 is d. In this embodiment, d is 5 cm.

[0036] To further optimize the solution, a number of high-speed water flow nozzles 6 are arranged in a matrix on the bottom plate of the debris flow drainage guide trough 1, and along the width direction of the debris flow drainage guide trough 1, the two high-speed water flow nozzles 6 located at the two ends are respectively arranged close to the two opposite edges of the bottom plate of the debris flow drainage guide trough 1.

[0037] Further optimization scheme, along the width direction of debris flow drainage channel 1, the spacing between two adjacent high-speed water flow nozzles 6 is between 10cm and 15cm, along the length direction of debris flow drainage channel 1, the spacing between two adjacent high-speed water flow nozzles 6 is between 10cm and 15cm.

[0038] like Figure 3 As shown, a plurality of high-speed water flow nozzles 6 are arranged in a matrix on the bottom plate of the debris flow drainage guide trough 1. Along the width direction of the debris flow drainage guide trough 1, the spacing between two adjacent high-speed water flow nozzles 6 is a, and the value of a is between 10cm and 15cm. Along the length direction of the debris flow drainage guide trough 1, the spacing between two adjacent high-speed water flow nozzles 6 is b, and b is between 10cm and 15cm.

[0039] To further optimize the solution, in the same debris flow drainage channel project, the spacing a and the spacing b take the same value.

[0040] According to a further optimized solution, the liquid level monitoring component includes a trigger switch component fixedly connected to the side wall of the debris flow guide channel 1. When the debris fluid 2 contacts the trigger switch component, the trigger switch component sends a signal to the intelligent controller.

[0041] As a further optimization solution, in this embodiment, the trigger switch element may be a contact sensor 4 . When the debris fluid 2 contacts the contact sensor 4 , the contact sensor 4 sends a monitoring signal to the intelligent controller 5 .

[0042] According to a further optimized solution, the distance between the trigger switch and the bottom plate of the debris flow drainage channel 1 is 1.5 m.

[0043] A further optimized solution also includes a water tank 8, which is connected to a water pump (not shown in the figure). The water outlet of the water pump is connected to several water inlet branches 9 through an inlet pipe 10, and the intelligent controller 5 is electrically connected to the water pump.

[0044] like Figure 1 As shown, the main function of the water reservoir 8 is to store enough water for the water spraying of a plurality of high-speed water flow nozzles 6. The water reservoir 8 is arranged at a safe position near the debris flow drainage channel 1 project.

[0045] According to a further optimization scheme, the water pressure generated by a single high-speed water flow nozzle 6 is between 4.5kN and 6.0kN, and the uniformly distributed load q of the high-speed water curtain formed by several high-speed water flow nozzles 6 at the bottom plate of the debris flow drainage channel 1 is between 30kPa and 40kPa.

[0046] The working process of this embodiment is as follows:

[0047] After a debris flow erupts, the debris within the debris flow ditch rapidly converges into the debris flow drainage channel 1 for discharge. As the depth of the debris flow 2 within the debris flow drainage channel 1 increases, when the mud level reaches the point of contact with the contact sensor 4, the contact sensor 4 promptly senses the debris flow 2 and transmits a monitoring signal to the intelligent controller 5. The intelligent controller 5 immediately activates a water pump, which pumps water from a reservoir 8 to a number of high-speed water nozzles 6. All of the high-speed water nozzles 6 simultaneously spray high-speed water, forming a high-speed water curtain that lifts the debris flow 2 within the debris flow drainage channel 1 upward. While the high-speed water curtain lifts the debris flow 2, the rapidly flowing debris flow 2 essentially avoids contact with the bottom plate of the debris flow drainage channel 1, significantly reducing the abrasive effect of the debris flow on the concrete material of the bottom plate of the debris flow drainage channel 1, thereby effectively protecting the bottom plate of the debris flow drainage channel 1 from debris flow abrasion.
