Description

Technical Field

[0001] The present application relates to the technical field of pumped storage power stations, and in particular to a device for preventing clogging of inner pipes in flood gullies in mountainous areas. Background Art

[0002] The geographical factors of pumped storage power station construction are characterized by a long construction period and a wide construction area. The external environmental factors are characterized by spanning multiple flood seasons, with multiple rivers, gullies and streams flowing through the construction area. The project's own factors include material yards, slag piles, living camps, underground caverns and high slopes that are easily affected by the flood season. Continuous rainfall or short-term heavy rainfall in mountainous areas during the flood season can easily cause natural disasters such as flash floods, landslides and mud-rock flows.

[0003] Considering that there are more heavy rainfalls during the typhoon season, in order to ensure that the construction area passes the flood season smoothly, the project usually arranges culverts, culverts and other interception and drainage measures on site to divert rainwater and natural water bodies, and prevent natural disasters caused by long-term erosion of slag bodies, material yards, and high slopes by precipitation. However, since pumped storage power station construction projects are usually built in mountainous areas or near mountains, the water flow is likely to increase during heavy rainfall, and mud, dead wood, gravel and other debris will enter the culvert, resulting in blockage of the culvert entrance or failure to discharge in time after entering the culvert, affecting the discharge section. At this stage, manual cleaning is usually adopted, but due to unsafe factors such as the small space of the culvert itself, insufficient light and ventilation inside the culvert, and the duration of heavy rainfall, manual entry into the culvert for cleaning is high-risk and difficult, and it is easy to cause safety accidents such as drowning or falling from a height. Summary of the invention

[0004] An embodiment of the present application provides a device for preventing clogging of an inner pipe in a flood gully in a mountainous area. The device for preventing clogging of an inner pipe in a flood gully in a mountainous area can effectively reduce the entry of debris such as dead wood and gravel into the culvert.

[0005] The anti-clogging device for culverts in flood gullies in mountainous areas provided in an embodiment of the present application includes a collector body, which is arranged at the entrance of the culvert. The collector body includes a buoyancy bin and at least one collecting bin, and the collecting bin has a first cavity and a first opening, the first opening is connected to the first cavity, and the first opening faces the flow direction of the water; the buoyancy bin has a second cavity and a second opening, the second opening is connected to the second cavity, and a buoyancy device is arranged in the second cavity of the buoyancy bin, and the buoyancy device can generate buoyancy in water; the collector body also includes a limiting device, and the limiting device can limit the collector body to a preset position at the entrance of the culvert.

[0011] The beneficial effects of the embodiments of the present application are:

[0012] The culvert anti-clogging device for flood gullies in mountainous areas includes a buoyancy bin and at least one collecting bin.

[0020] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0021] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0022] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0023] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0024] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0025] like Figure 1-4As shown, an embodiment of the present application provides an anti-clogging device for an inner pipe in a flood gully in a mountainous area, which includes a collector body 1, which is arranged at the entrance of a culvert 2, and the collector body 1 includes a buoyancy bin 3 and at least one collecting bin 4, the collecting bin 4 has a first cavity 5 and a first opening 6, the first opening 6 is connected to the first cavity 5, and the first opening 6 faces the flow direction of the water; the buoyancy bin 3 has a second cavity 7 and a second opening, the second opening is connected to the second cavity 7, and a buoyancy device 8 is arranged in the second cavity 7 of the buoyancy bin 3, and the buoyancy device 8 can generate buoyancy in water; the collector body 1 also includes a limiting device, which can limit the collector body 1 to a preset position at the entrance of the culvert 2.

[0026] After the mountain flood gully culvert anti-blocking device in this embodiment is installed, the first opening 6 of the collecting bin 4 faces the flow direction of the water flow, so that dead wood, gravel and other debris can enter the first cavity 5, and thus be intercepted outside the culvert 2, effectively preventing the debris in the gully and river from entering the culvert 2 and causing the culvert 2 to be blocked; in addition, the buoyancy device 8 in the buoyancy bin 3 can generate buoyancy in the water so that the collecting bin 4 can better intercept floating debris without affecting the normal flow of the flood discharge channel, further reducing the risk of blockage of the culvert 2. After the mountain flood gully culvert anti-blocking device is deployed to intercept debris, it is only necessary to actively clean the device regularly or after heavy rainfall on both sides of the flood discharge channel by mechanical and manual methods, which not only reduces the probability of accidents caused by manual cleaning, but also ensures the normal flow capacity of the culvert 2.

[0027] like Figure 2-4 As shown, in a specific embodiment, the collector body 1 has a plurality of mesh walls, the mesh walls include angle steels 9 and wire meshes 10, the angle steels 9 enclose a rectangular frame structure, and the wire meshes 10 are arranged in the frame structure. It should be noted that the mesh size of the mesh wall can be preset according to the actual environment, so it is not specifically limited in this article.

[0028] like Figure 1-3 As shown, in a specific embodiment, a steel wire mesh 10 is welded to the angle steel 9, the steel wire mesh 10 is a galvanized steel wire mesh, at least a portion of the warehouse wall of the buoyancy warehouse 3 is provided with a dense steel wire mesh 11, and the buoyancy warehouse 3 is provided with a warehouse door capable of opening and closing the second cavity 7 at the position of the second opening, and the second cavity 7 can be opened through the warehouse door to perform operations such as placing or replacing the buoyancy device 8. In addition, in order to reduce the impact of floods on the warehouse door, the direction of the second opening can be set to a different side from the first opening 6.

[0029] like Figure 1-3As shown, in a specific embodiment, the limiting device includes a plurality of limiting rods 12, a movable lock buckle 13 is provided on the side wall of the collector body 1, and a pre-buried ring 15 is provided on the side wall 14 of the flood discharge channel close to the culvert 2, one end of the limiting rod 12 is connected to the collector body 1 through the movable lock buckle 13, and the other end is connected to the side wall 14 of the flood discharge channel through the pre-buried ring 15. Generally speaking, the limiting rod 12 can be a steel pipe, which can ensure the limiting strength and reduce the use cost. The limiting rod 12 can make the collector body 1 adjust its height up and down with the water flow when the water level rises without displacement in the direction of the water flow.

[0030] like Figure 1-3 As shown, in a specific embodiment, the number of collecting bins 4 is at least two, and at least two collecting bins 4 are respectively located on both sides of the buoyancy bin 3 in the height direction, and the buoyancy device 8 includes a rubber inflatable airbag. Specifically, when the water level is low, the collector body 1 automatically falls to the bottom, and the slag is intercepted by the collecting bin 4 at the bottom of the buoyancy bin 3; when the water level rises due to heavy rainfall, the buoyancy device 8 in the buoyancy bin 3 generates buoyancy, and automatically adjusts its position through the limit device according to the height of the water level, and uses the collecting bins 4 on the upper and lower sides of the buoyancy bin 3 to intercept floating debris together without affecting the normal flow of the flood discharge channel, thereby reducing the risk of blockage of the culvert 2.

[0031] After the rainfall, the dead wood, branches and other debris in the collection bin 4 are cleaned up by mechanical lifting and manual disassembly and cleaning, which effectively improves the efficiency of slag cleaning and changes the slag cleaning method from passive response to active prevention. The gully debris is "intercepted" at the first time, the flood discharge capacity is fully released, and the potential safety hazards of manual slag cleaning are eliminated.

[0032] In addition, the device is easy to install, low cost, safe and effective, and easy to promote. Collectors of different sizes and shapes can be used according to the width of the river channel and gully channel; for river channels and gullies without side walls, a limit rod 12 (fixed vertical rod) can be used on the side bank to connect the wire rope and the collector body 1 for fixation; in summary, the device can be widely used in the interception of gullies and river debris in water conservancy and hydropower projects such as pumped storage power stations.

[0033] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
