Description

Technical Field

[0001] This utility model relates to the technical field of water emergency rescue, specifically to a wrinkle-flow waterway structure. Background Technology

[0002] Currently, water rescue has become an important part of emergency rescue missions. Common dangerous current patterns in water rescue include: tumbling currents, covering currents, frowning currents, smiling currents, whirlpools, and V-shaped currents. Training in particularly complex aquatic environments can easily lead to a decline in trainees' psychological resilience and judgment, resulting in anxiety, fear, and a reluctance to attempt the task, thus affecting training effectiveness. In recent years, my country has built or is building nearly ten rapids training facilities.

[0003] The formation of the flow pattern in a rapid waterway mainly depends on hydraulic conditions and boundary conditions. The most important factor in hydraulic conditions is the flow velocity or drop, while the most important factors in boundary conditions are the longitudinal slope of the waterway floor, the boundary line shape, and the shape of obstacles.

[0004] When the current waterway floor uses a fixed structure, the longitudinal slope and gradient of the floor cannot be changed. This means that the water level difference over a specific horizontal length is constant, and therefore the water flow velocity is also constant, resulting in only a uniform wrinkled flow pattern. However, in reality, due to different hydraulic and boundary conditions, the wrinkled flows encountered during actual rescue operations usually have different flow patterns. Therefore, designing waterways capable of generating different wrinkled flow patterns while reducing construction and operating costs is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

By setting a replaceable bottom plate module, the height and slope of the bottom plate can be adjusted according to the needs of the wrinkled flow pattern, and the longitudinal slope boundary line of the bottom plate can be changed to obtain different water flow velocities or drops, thereby changing the intensity of the wrinkled flow pattern and meeting the requirements of different training difficulties.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a wrinkled flow waterway structure, including a first blocking section, a slope section and a second blocking section arranged sequentially from upstream to downstream, wherein the bottom of the first blocking section is higher than the bottom of the second blocking section;

The first water-blocking module and the second water-blocking module are respectively located on opposite sides of the waterway structure, and the side of the second water-blocking module closer to the upstream side forms a wrinkle flow generation area.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the side of the base plate module closest to the upstream is in close contact with the first vertical surface, and the side of the base plate module closest to the downstream is in close contact with the second vertical surface.

[0013] Furthermore, a first locking element is pre-embedded at the bottom of the first blocking section, and the first locking element extends out of the top surface of the fixed base plate; the bottom of the first water-blocking module is detachably connected to the first locking element.

[0014] Furthermore, the first locking element is located at the downstream end of the first blocking section.

[0031] Example 1

[0032] A vortex flow channel structure includes a first blocking section 1, a ramp section 2, and a second blocking section 3 arranged sequentially from upstream to downstream. The bottoms of the first blocking section 1, the ramp section 2, and the second blocking section 3 are all horizontal. The bottom of the first blocking section 1 is higher than the bottom of the second blocking section 3, and the bottom of the ramp section 2 is lower than the bottom of the second blocking section 3. The bottom of the ramp section 2, near the upstream end, is connected to the bottom of the first blocking section 1 via a first vertical surface 22, and the bottom of the ramp section 2, near the downstream end, is connected to the bottom of the second blocking section 3 via a second vertical surface 23.

[0033] In addition, the waterway structure in this embodiment also includes a fixed base plate 4, which covers the bottom of the first blocking surface, the first vertical surface 22, the bottom of the slope surface, the second vertical surface 23, and the bottom of the second blocking surface.

[0034] A first locking element 11 is pre-embedded at the bottom of the first blocking section 1, and the first locking element 11 extends out of the top surface of the fixed base plate 4. In this embodiment, the first locking element 11 is located at the downstream end of the first blocking section 1.

[0035] A second locking member 31 is pre-embedded at the bottom of the second blocking section 3, and the second locking member 31 extends out of the top surface of the fixed base plate 4. In this embodiment, the second locking member 31 is located at the end of the second blocking section 3 near the upstream end.

[0036] By utilizing the first locking element 11 and the second locking element 31 to set water-blocking modules of different shapes in the first blocking section 1 and the second blocking section 3 respectively, different water flow patterns such as boiling lines, tumbling flows, furrowed flows, and vortex flows can be formed in the waterway structure under the action of different water-blocking modules. This design can reduce the construction scale and save construction and operating costs.

[0037] In this embodiment, a replaceable first water-blocking module 6 is provided in the first blocking section 1, and a replaceable second water-blocking module 7 is provided in the second blocking section 3. The bottom of the first water-blocking module 6 is detachably connected to the first locking fastener 11, and the bottom of the second water-blocking module 7 is detachably connected to the second locking fastener 31. The first water-blocking module 6 and the second water-blocking module 7 are respectively located on opposite sides of the waterway structure, and the side of the second water-blocking module 7 closer to the upstream side forms a wrinkled flow generation zone 8.

[0038] A third locking element 21 is pre-embedded at the bottom of the ramp section 2, extending beyond the top surface of the fixed base plate 4. The ramp section 2 is equipped with a replaceable base plate module 5, the bottom of which is detachably connected to the third locking element 21. The top of the base plate module 5 has an inclined surface 51. The upstream side of the base plate module 5 is in close contact with the first vertical surface 22, and the upstream end of the inclined surface 51 is flush with and connected to the bottom of the first blocking section 1. The downstream side of the base plate module 5 is in close contact with the second vertical surface 23, and the downstream end of the inclined surface 51 is flush with and connected to the second blocking section 3.

[0039] This invention, by incorporating a replaceable base plate module 5, a first water-blocking module 6, and a second water-blocking module 7, allows for adjustment of the base plate's height and slope to achieve different water flow velocities or drops, thereby altering the intensity of the resulting wrinkled flow and meeting varying training difficulty requirements. Furthermore, by modifying the longitudinal slope boundary line of the base plate and the shapes of the first and second water-blocking modules 6 and 7, the boundary conditions can be further altered, thus generating wrinkled flows with different flow patterns.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
