Description

Technical Field

[0001] The utility model relates to the technical field of water emergency rescue, in particular to a turning type one-pump double-flow channel structure. Background Art

[0002] Affected by extreme weather, the number of people trapped in floods has increased significantly, water rescue tasks have become increasingly arduous, and the rescue situation has become increasingly severe. For rescue personnel, traditional water rescue simulation training is limited to simulating rescue training such as drowning and flooding in natural river waters. Training in natural venues such as rivers is very dangerous, and emergency rescue units generally conduct less water rescue training. Therefore, water rescue simulation facilities have emerged;

[0003] For example, the Chinese invention patent with patent publication number CN115909837A discloses a hydraulic design method for a rapids waterway and a comprehensive training base for water rescue, which forms a water rescue training base by sequentially connecting rapids waterways with different flow patterns;

[0004] However, the water rescue training base covers a large area, and a lot of open space is idle due to unreasonable use; at the same time, whirlpool currents usually exist at bends in natural river waters, and the existing water rescue training base has not designed whirlpool currents at bends; in addition, rescue personnel will consume a lot of physical strength when training in intense flow channels. In actual use, it is found that there is physical exhaustion caused by continuously passing through multiple intense flow channels. If no safety rest area is set up, accidents are likely to occur when the user is physically exhausted; at the same time, if the safety rest area is not used reasonably, it will inevitably cause waste.

[0015] Preferably, the length of the first obstacle combination is 1 / 3-1 / 2 of the width of the right-angle flow channel.

[0016] Preferably, the minimum spacing between the symmetrically arranged second obstacle combinations is 1 / 4-1 / 3 of the width of the inlet flow channel.

[0017] Preferably, the second vortex flow channel includes a straight portion and a recessed portion arranged on one side of the straight portion, and a side wall of the straight portion away from the recessed portion is provided with a third obstacle combination extending toward the recessed portion.

[0018] Preferably, a fourth obstacle combination is arranged on the same side wall of the input end of the straight portion and the recessed portion, and a fifth obstacle combination is symmetrically arranged on two opposite side walls of the output end of the straight portion.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] The utility model adopts a one-pump dual-flow channel system, which does not require the construction of multiple independent water pools, saving the cost of building and maintaining water pump components. At the same time, through the design of dual flow channels, flow channel sections of various flow states such as boiling flow, vortex flow, V-shaped flow, etc. that meet the design requirements can be set in a limited space.

[0025] The first vortex flow channel is widened at the bend of the flow channel and combined with obstacles. The inner side allows trainees to simulate the vortex effect at a bend in the wild, and when they are exhausted, they flow outwards due to centrifugal force and come into contact with the outer wall, which prevents the trainees from continuing to flow downstream. The outer side provides a safer environment for temporary rest for trainees who are exhausted.

[0026] The straight section of the flow channel is widened to form a recessed portion, which not only has a lower water flow rate, providing a safer environment for trainees to temporarily rest, but also, in order to avoid wasting limited space, a second vortex flow channel is formed here through a combination of obstacles to improve space utilization.

[0034] Example:

[0035] A turning type one pump double flow channel structure, such as Figure 1 As shown, it includes an inlet pool 1, a flow channel 2 and an outlet stilling pool 3.

[0039] like Figure 1 , 2As shown, the flow channel 2 on the left side is provided with a right-angle turn, and the right-angle turn is horizontally widened to form a first vortex flow channel 21. The first vortex flow channel 21 includes a right-angle flow channel 211, an inlet flow channel 212 and an outlet flow channel 213 in a right-angle shape. The inlet flow channel 212 is connected to the input end of the right-angle flow channel 211 and the inner side walls are arranged in the same plane. The outlet flow channel 213 is connected to the output end of the right-angle flow channel 211 and the inner side walls are arranged in the same plane; the width of the outlet flow channel 213 is smaller than the width of the output end of the right-angle flow channel 211, the width of the inlet flow channel 212 is smaller than the width of the input end of the right-angle flow channel 211, and the width of the inlet flow channel 212 is smaller than the width of the upstream flow channel 2; the width of the outlet flow channel 213 is the same as the width of the flow channel 2, and the width of the right-angle flow channel 211 is larger than the width of the flow channel 2.

[0040] A first obstacle assembly 214 is provided on the inner side wall of the input end of the right-angle flow channel 211. The first obstacle assembly 214 extends from the inner side wall of the input end of the right-angle flow channel 211 to the outer side wall of the input end. The length of the first obstacle assembly 214 is 1 / 3-1 / 2 of the width of the input end of the right-angle flow channel 211. The first obstacle assembly 214 is perpendicular to the inner side wall of the input end of the right-angle flow channel 211.

[0041] The second obstacle assembly 215 is symmetrically arranged on the inner and outer side walls of the inlet flow channel 212. The second obstacle assembly 215 is in an "eight" shape. The spacing between the second obstacle assemblies 215 symmetrically arranged along the direction of water flow gradually decreases, and the minimum spacing is 1 / 4-1 / 3 of the width of the inlet flow channel 212.

[0042] like Figure 1 , 3 As shown, the straight section of the flow channel 2 is provided with a second vortex flow channel 22, and the second vortex flow channel 22 includes a straight portion 221 and a recessed portion 222 provided on one side wall of the straight portion 221, the straight portion 221 is equivalent to the other non-widened portion of the flow channel 2, the width of the recessed portion 222 is substantially equal to the width of the straight portion 221, and a third obstacle assembly 223 extending toward the recessed portion 222 is vertically provided on the side wall of the straight portion 221, the third obstacle assembly 223 is relatively located in the middle of the recessed portion 222, and the length of the third obstacle assembly 223 is 2 / 3-1 of the width of the straight portion 221 of the flow channel 2;

The fifth obstacle assembly 225 is relatively located downstream of the recessed portion 222. The length of the fifth obstacle assembly 225 is 1 / 4-1 / 3 times the width of the flow channel 2 / straight portion 221. The fifth obstacle assembly 225 can be arranged in two groups symmetrically.

[0045] The top wall of the obstacle combination is higher / lower than the water surface and can be adjusted according to needs. Figure 2 , 3 The red lines in the figure mark the flow trajectory of the water.

[0046] Working principle:

[0047] The water pump assembly in the water inlet pool 1 delivers water to the output ports on both sides thereof and enters two flow channels 2 respectively. The flow channels 2 are designed with rapid flow channels of various shapes for simulation training, and the water flow finally flows into the outlet stilling pool 3.

[0048] The water flow in the outlet stilling pool 3 flows into the rescue simulation training pool 5, and the rescue simulation training pool 5 can be designed into various training simulation scenes.

[0049] The water pump assembly draws water from the front pool 51 in the rescue simulation training pool 5 into the water inlet pool 1 to achieve circulation.

[0050] The space combination in the two flow channels 2 forms various water rescue training simulation scenes.

[0051] When water flows from an area with a smaller width to an area with a larger width, the flow rate decreases, providing a buffer space for trainees.

[0052] like Figure 2 As shown, the upstream water flow increases the flow velocity through the narrowed inlet flow channel 212, and the second obstacle combination 215 realizes a high flow velocity in the middle and a low flow velocity on both sides; then, under the blocking effect of the first obstacle combination 214, the water flow is guided to flow quickly to the outer wall of the right-angle flow channel 211, while the flow velocity of the water flow (inside) behind the first obstacle combination 214 is relatively slow to form a speed difference, and the right-angle flow channel 211 is a right-angle shape so that a vortex is formed therein, and the water flow in the right-angle flow channel 211 flows to the narrowed outlet flow channel to further improve the vortex effect behind the first obstacle combination 214. This setting is conducive to training firefighters in ship control skills in right-angle turns with vortices.

[0053] like Figure 3 As shown, the upstream water flow is blocked by the fourth obstacle combination 224, so that the flow velocity on the left side of the downstream of the fourth obstacle combination 224 is slow and the flow velocity on the right side is fast; it continues to flow downward and is guided to flow rapidly to the concave area 222 under the action of the third obstacle combination 223, and the above cooperation forms a first vortex on the upper part of the concave area 222;

[0054] The water flow continues to flow downward, and under the blocking effect of the fifth obstacle combination 225, a second vortex is formed in the area between the third obstacle combination 223 and the fifth obstacle combination 225, and the first vortex and the second vortex rotate in opposite directions. This setting is conducive to training firefighters to control the ship in two consecutive vortices with different rotation directions.
