Description

Technical Field

[0001] The invention belongs to the technical field of debris flow slope protection devices, and in particular relates to a debris flow interception and protection device. Background Art

[0002] Debris flow is a torrent formed after heavy rain and floods dilute the soft soil mountains containing sand and gravel after saturation. It can be divided into mud flow, debris flow and water-rock flow according to the different solid matter components. Commonly used prevention and control measures mainly include gravity dam, grating dam, gabion stone cage dam and flexible protection system for debris flow to reduce the damage of debris flow to downstream buildings. Because the debris flow contains some large stones, after colliding with the interception dam at high speed together with the mud, it is easy to cause damage to the structure of the interception dam.

[0003] In addition, during the process of intercepting debris flow, the debris carried by the debris flow can easily block the reserved holes of the interception dam, causing its flood discharge capacity to decrease, resulting in high water levels, overflowing the dam and other problems. At this time, the interception dam will be difficult to guarantee the interception effect of solid materials such as slag and silt. In serious cases, it may also form a barrier lake due to the poor flow of gullies, and then burst, causing more serious secondary disasters; the slopes on both sides of the upstream of the interception dam are usually soil layers. Due to the lack of fixed structures, they are easily washed away and collapsed by debris flows when debris flows occur, becoming the material source conditions of debris flows. Existing debris flow protection measures also include flexible protective nets, but the ability of flexible protective nets to directly withstand impact loads is limited, and they are prone to failure when encountering large-scale debris flow impacts.

[0004] Therefore, this solution proposes a debris flow interception and protection device, which adopts a concept different from the existing technology and provides a new solution for the protection of debris flow. Summary of the invention

DETAILED DESCRIPTION

[0027] In order to more clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0028] See also Figure 1-Figure 8A debris flow interception and protection device comprises a buffer structure 1, a buffer structure 2 and a buffer structure 3 which are arranged and fixed on a hillside from top to bottom, a drainage component is arranged on the buffer structure 2, the drainage component is arranged between the buffer structure 1 and the buffer structure 2, and a suction component is arranged above the buffer structure 2; The buffer structure 1 is linked with the buffer structure 2 through the gear assembly 15 to prevent the buffer structure 2 from tilting. The buffer structure 2 is connected with the buffer structure 3 through the gear assembly 2 to limit the buffer structure 2 downward.

[0029] The buffer structure 1 includes a support column 2 11 vertically positioned on the sloping ground, a movable clamp 10 rotatably arranged on the top of the support column 2 11, an air bag tube 17 inserted into the movable clamp 10, and an air pump 1 connected to the air bag tube 17.

[0030] Support column 2 11 can be a concrete column, or a columnar structure of metal material or stone or wood. The following support column 1 2 and support column 3 14 are the same as support column 2 11; the movable clamp 10 is a prior art and will not be described in detail here. The attached figure is a schematic diagram for special explanation.

[0031] The buffer structure 2 includes two parallel tracks 1, a support column 2 fixedly supported at the bottom end of the track 1, a transfer box 3 movably arranged on the track 1, and a power wheel 4 arranged at the bottom end of the transfer box 3, and the power wheel 4 is movably arranged on the track 1; a release door 32 is arranged on one side of the transfer box 3, and two adjacent transfer boxes 3 are connected by a flexible rope 31.

[0032] When the transfer box 3 arrives at a specific place, the release door 32 is opened, and the debris flow automatically flows out to the area to be treated for storage or filtering. The treatment of debris flow belongs to the existing technology and can be performed according to the actual situation, which will not be described in detail here.

[0033] The buffer structure three includes a support column three 14 vertically positioned on the sloping ground, a movable clamp two 13 rotatably arranged at the top of the support column three 14, an air bag tube two 12 inserted into the movable clamp two 13, and an air pump two connected to the air bag tube two 12.

[0034] Air pump 1 and air pump 2 belong to the prior art and will not be described in detail here or shown in the drawings. During actual installation, they can be placed in a protective cover that is positioned underground or in a sheltered area.

[0035] The drainage assembly includes an inclined plate 5 with one end hinged on one side of the transfer box 3, an arc rod 51 with one end fixedly connected to the bottom surface of the inclined plate 5, and an arc spring 52 sleeved on the outside of the arc rod 51. The rotation center of the arc rod 51 is located on the hinge center of the inclined plate 5 and the transfer box 3, and the bottom end of the arc spring 52 rests on the outside of the transfer box 3.

[0036] The other end of the inclined plate 1 5 is hingedly connected to one end of the inclined plate 2 6, the bottom surface of the inclined plate 2 6 is fixedly connected to one end of the arc rod 1 62, the outer side of the arc rod 1 62 is sleeved with an arc spring 1 63, the other end of the arc rod 2 51 movably passes through the inclined plate 1 5, the other end of the arc rod 2 51 is fixed with a retaining ring 64, the retaining ring 64 and the arc spring 1 63 respectively abut against the two sides of the inclined plate 1 5; A support seat is fixed to the bottom end of the inclined plate 2 6, and a support wheel 61 is movably arranged on the support seat. The support wheel 61 can walk on the slope.

[0037] The suction assembly includes a vertical column 93 whose bottom end is fixed to the transfer box 3, a suction pipe 9 which is rotatably connected to the vertical column 93 at the side through a hinge shaft 92, a baffle 8 fixed to one end of the suction pipe 9, and a suction pump 91 connected to the side of the suction pipe 9, and the suction pump 91 rests on the vertical column 93.

[0038] The ejection end of the suction pipe 91 may be distributed at an angle to the moving direction of the debris flow, that is, the ejection end of the suction pipe 91 is curved, which helps to disperse the debris flow.

[0039] The gear assembly 15 includes a fixing seat 111 disposed on the supporting column 2 11, a connecting rod 112 hingedly connected at one end to the fixing seat 111, a gear rod 113 hingedly connected at one end to the other end of the connecting rod 112, a gear 114 meshingly connected to the outer side of the gear rod 113, a gear rod 2 115 meshingly connected to the outer side of the gear 114, a vertical gear rod 153 fixedly connected at the bottom end to the end of the gear rod 2 115, and an embedded column 154 vertically fixed to the top end of the vertical gear rod 153; The gear rod 113 and the gear rod 2 115 are movably arranged on the limiting rod 116 , and the embedded column 154 is embedded in the lower end of the track 1 .

[0040] The movement of the gear rod 1 113 drives the gear rod 2 115 to move in the opposite direction, thereby causing the vertical gear rod 153 and the embedded column 154 to resist against the track 1 .

[0041] Gear assembly 2 includes gear 2 155 meshingly connected to the outer side of the vertical gear rod 153, an inclined gear rod 152 meshingly connected to gear 2 155, and a fixed rod 151 with one end fixedly connected to the inclined gear rod 152, and the other end of the fixed rod 151 is fixedly connected to the support column 3 14.

[0042] When the buffer structure 3 is impacted by the debris flow, it tends to rotate. At this time, the inclined gear rod 152 exerts force on the gear 2 155, and the gear 2 155 exerts force on the vertical gear rod 153 to make it downward.

[0043] It should be noted that due to the reinforcement effect, when actually impacted by a debris flow, in most cases, gear one 114 and gear two 155 will not actually rotate significantly, but only play a role in transmitting force, thereby ensuring overall stability.

[0044] The specific working process of the present invention is as follows: When the interception and protection device is in use, it is fixed on a hillside where debris flow is prone to occur. Buffer structure 1, buffer structure 2 and buffer structure 3 can be designed as an annular structure, so that the movement of the transfer box 3 can be repeated to transfer the debris flow from one place to another place to be processed. For example, a filtering system can be designed to filter and process the debris flow after transfer.

[0045] In this scheme, buffer structure 1, buffer structure 2 and buffer structure 3 are designed, and the three cooperate with each other. The airbag tube 1 7 and the airbag tube 2 12 are inflated by an air pump, so that the airbag tube 1 7 contacts the inner side of the movable clamp 1 10, and the airbag tube 2 12 contacts the inner side of the movable clamp 2 13. The movable clamp 10 and the movable clamp 2 13 are both existing technologies and will not be described in detail here; the flexible barrier of the airbag tube 1 7 and the airbag tube 2 12 helps to reduce the movement speed of the debris flow and avoid the expansion of the area of ​​the debris flow; A buffer structure 2 is provided. In addition to having a buffering effect, the principle of track 1 transportation is utilized to transfer the debris flow to other locations, disperse the debris flow, and thereby avoid greater damage to a single area due to excessive concentration of debris flow. Such an invention concept does not appear in the current prior art. What is important is that the construction of a simple track 1 transportation on the hillside is a low-cost investment. When no debris flow disaster occurs, it can also be used as external transportation to facilitate travel for people in mountainous areas.

[0046] Multiple buffer structures 1, 2 and 3 are arranged on the hillside to form a multi-layer buffer, which can avoid the expansion of the debris flow area to the greatest extent; specifically, when the debris flow just begins to form, the movement speed and volume of the debris flow are relatively small. At this time, part of the debris flow is transported out. Since the buffer structure 2 is a ring-shaped structure, the transportation process can be carried out continuously.

[0047] A drainage assembly is provided, and the inclined plate 1 5 and the inclined plate 2 6 are both movable parts. Under the action of the arc rod 1 62, the arc spring 1 63, the arc rod 2 51, and the arc spring 2 52, they can automatically rotate up and down according to the terrain conditions. On the one hand, the debris flow can be diverted into the transfer box 3 to reduce the impact of the debris flow on the outside of the transfer box 3. On the other hand, the movable adjustment of the inclined plate 1 5 and the inclined plate 2 6 can be adaptively adjusted according to the actual terrain of the hillside; A suction assembly is provided in the transfer box 3, which helps to increase the overall counterweight of the transfer box 3 and improve the impact resistance of the transfer box 3; under the action of the suction pump 91, the debris flow enters from one end of the suction pipe 9 and is sprayed out from the other end in a scattered manner, thereby avoiding the debris flow from causing greater impact damage due to excessive concentration; Gear assembly 1 15 and gear assembly 2 are provided, so that buffer structure 1 and buffer structure 2 are linked together. When buffer structure 1 is impacted by a debris flow, it is converted into an anti-tilt limit for buffer structure 2. At the same time, buffer structure 2 and buffer structure 3 are linked together. When buffer structure 3 is impacted by a debris flow, it is converted into a downward pressure limit for buffer structure 2, thereby ensuring the stability of the entire system.

[0048] Technical features not described in the present invention can be achieved through or by adopting existing technologies and will not be described in detail here. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
