Description

Technical Field

[0001] This utility model relates to the field of fire rescue technology, and in particular to a dangerous water flow simulation device. Background Technology

[0002] River rescue is a common task in fire and rescue operations. Due to the complex and changeable river environment, various dangerous water currents often form, such as turbulent currents, whirlpools, inverted V-shaped currents, smiling currents, upright V-shaped currents, and frowning currents. If firefighters cannot accurately assess the water conditions, not only will it be difficult to carry out effective rescue operations, but it may also endanger the safety of the firefighters themselves.

[0003] However, in current firefighting training, firefighters often lack a direct understanding of the formation conditions and specific characteristics of various dangerous water flows. Therefore, there is an urgent need to develop a dangerous water flow simulation device that can simulate and reproduce various dangerous water flow scenarios, helping firefighters to gain a deeper understanding of the formation mechanisms and characteristics of different dangerous water flows, thereby improving rescue capabilities and safety levels. Utility Model Content

[0004] To address the aforementioned technical problems, this invention provides a dangerous water flow simulation device. This device can simulate and reproduce various dangerous water flow scenarios, helping firefighters to gain a deeper understanding of the formation mechanisms and characteristics of different dangerous water flows, thereby improving rescue capabilities and safety levels.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a dangerous water flow simulation device, characterized in that:

[0006] It includes a first ramp and a first observation box. The outlet of the first ramp is connected to the first observation box, and the outlet of the first ramp is higher than the outlet of the first observation box to form a height difference. When the water flows into the first observation box through the first ramp, it forms a tumbling flow through the height difference.

[0007] It includes a second ramp and a second observation box. The outlet of the second ramp is connected to the second observation box. A baffle is installed in the second observation box at the position relative to the outlet of the second ramp. When the water flows into the second observation box through the second ramp, it hits the baffle and forms a vortex flow.

[0008] The device includes a triangular obstacle, which is installed on any ramp. The flat end of the triangular obstacle faces the direction of the water flow on the ramp, and the pointed end faces the direction of the water flow out. When the water flows through the triangular obstacle, it hits the flat end and then forms an inverted V-shaped flow through the pointed end.

[0009] It includes a cylindrical obstacle, which is set on any ramp. When water flows through the cylindrical obstacle, it impacts the cylindrical obstacle to form a smile flow.

[0010] It includes a left obstacle and a right obstacle, which are respectively set on the left and right sides of any ramp. There is a gap between the left obstacle and the right obstacle. Water flows through the gap between the left obstacle and the right obstacle to form a positive V flow.

[0011] The system includes a sloping barrier and a flat barrier. The sloping barrier and the flat barrier are installed on any ramp and are arranged sequentially along the direction of water flow. The sloping barrier and the side wall of the ramp form a narrowing opening facing the direction of water flow. The flat barrier is located adjacent to the narrowing opening and is positioned directly opposite to the narrowing opening. After the water flows through the narrowing opening, it accelerates and impacts the flat barrier to form a wrinkled flow.

[0012] It includes multiple bottom-mounted barriers, which are set on the bottom surface of any ramp. When water flows through the bottom-mounted barriers, it forms bubbles.

[0013] As a further improvement of this utility model, the first ramp, the first observation box, the second ramp, and the second observation box are arranged in descending order and are connected in sequence, so that the water flows through the first ramp, the first observation box, the second ramp, and the second observation box in sequence.

[0014] As a further improvement of this utility model, it also includes a water storage tank, a water pump, and a water outlet tank. The water storage tank stores water, and the water pump is installed on the water storage tank and connected to the water outlet tank through a pipe for drawing water from the water storage tank to the water outlet tank. The first ramp is provided with a water inlet, and the water outlet tank is connected to the water inlet of the first ramp.

[0015] As a further improvement of this utility model, it also includes a bracket, which is set on the water storage tank, and the water outlet tank, observation box and ramp are set on the bracket.

[0016] As a further improvement of this utility model, the bottom of the water storage tank is provided with casters.

[0017] As a further improvement of this utility model, it also includes a third ramp, a fourth ramp, and a fifth ramp. The triangular obstacle and the cylindrical obstacle are arranged on the third ramp, the left obstacle, the right obstacle, the oblique barrier obstacle, and the flat barrier obstacle are arranged on the fourth ramp, and the bottom-mounted obstacle is arranged on the fifth ramp.

[0018] As a further improvement of this utility model, the second observation box, the third ramp, the fourth ramp and the fifth ramp are arranged in descending order and are connected in sequence, so that the water flows through the second observation box, the third ramp, the fourth ramp and the fifth ramp in sequence.

[0019] As a further improvement of this utility model, the observation box is a transparent glass box; the ramp is a transparent glass ramp.

[0020] As a further improvement of this utility model, the ramp is inclined from top to bottom, with the upper side of the ramp being the water inlet and the lower side being the water outlet, and the water flow is from the water inlet to the water outlet.

[0021] The beneficial effects of this utility model are as follows: By setting up different observation boxes, ramps and obstacles, this utility model can highly simulate and intuitively display various dangerous water flow patterns, enabling firefighters to clearly observe the formation conditions and characteristics of different flow patterns in the laboratory or training ground, avoiding the safety risks brought about by directly entering natural water areas for training. It is suitable for firefighter water rescue training, emergency rescue drills and teaching demonstrations. Firefighters can repeatedly observe and analyze the formation process of different flow patterns through this device, deepen their understanding of dangerous water flows, and thus improve their rescue judgment and emergency response capabilities.

Detailed Implementation

[0024] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0025] like Figure 1 As shown, a dangerous water flow simulation device includes a water storage tank 1, a water pump 2, a support 3, an outlet tank 4, multiple observation boxes, and multiple ramps. The water storage tank 1 stores water. The water pump 2 is mounted on the water storage tank 1 and connected to the outlet tank 4 via a pipe, used to pump water from the water storage tank 1 to the outlet tank 4. The outlet tank 4, multiple observation boxes, and multiple ramps are fixed to the support 3, which is fixed to the water storage tank 1. The bottom of the water storage tank 1 is equipped with casters 101, which facilitate the overall movement of the device.

[0026] The water outlet tank 4, first ramp 5, first observation box 6, second ramp 7, second observation box 8, third ramp 9, fourth ramp 10, and fifth ramp 11 are arranged sequentially from high to low and are interconnected. Each ramp is inclined downwards at a slope of 5-30°. The upper side of the ramp is the water inlet, and the lower side is the water outlet. Water flows from the water inlet to the water outlet. Through this arrangement, water flow is achieved. Water pump 2 draws water to the water outlet tank 4, which is connected to the water inlet of the first ramp 5. The water flows sequentially through the first ramp 5, first observation box 6, second ramp 7, second observation box 8, third ramp 9, fourth ramp 10, and fifth ramp 11. The opening of the fifth ramp 11 is located on the water storage tank 1, ultimately causing the water to return to the water storage tank 1, thus achieving water circulation.

[0027] All observation boxes and ramps are made of transparent glass or transparent acrylic to facilitate observation of water flow patterns.

[0028] All obstacles are made of stones or slabs and are placed on the ramp for easy modular installation. They can also be glued to the ramp.

[0029] The outlet 501 of the first ramp 5 is connected to the first observation box 6, and the outlet of the first ramp 5 is at least 15cm higher than the outlet 601 of the first observation box 6 to form a height difference. When the water flows into the first observation box 6 through the first ramp 5, it forms a tumbling flow through the height difference.

[0030] The outlet 701 of the second ramp 7 is connected to the second observation box 8. The second observation box 8 is equipped with a baffle 801 at the position of the outlet 701 of the second ramp 7. When the water flows into the second observation box 8 through the second ramp 7, it hits the baffle 801 and then swirls along both sides of the baffle 801 to form a vortex flow.

[0031] The triangular obstacle 12 is set on the third ramp 9. The flat end of the triangular obstacle 12 faces the direction of the water flow on the ramp, and the pointed end faces the direction of the water flow out. When the water flows through the triangular obstacle 12, it hits the flat end and splits along the pointed end to form an inverted V-flow.

[0032] A cylindrical obstacle 13 is installed on the third ramp 9. The cylindrical obstacle 13 is used to simulate a bridge pier. When the water flows through the cylindrical obstacle 13, it impacts the cylindrical obstacle 13 to form a smile flow.

[0033] The left obstacle 14 and the right obstacle 15 are respectively set on the left and right sides of the fourth ramp 10. There is a 10cm gap between the left obstacle 14 and the right obstacle 15. After the water flows through the gap between the left obstacle 14 and the right obstacle 15, it forms a positive V flow.

[0034] The inclined barrier 16 and the flat barrier 17 are installed on the fourth ramp 10, and the inclined barrier 16 and the flat barrier 17 are arranged sequentially along the water flow direction. The inclined barrier 16 forms a 45° angle with the side wall of the ramp, so that a narrow opening 1601 facing the water flow direction is formed between the two. The flat barrier 17 is 15cm away from the narrow opening 1601 and is set directly opposite the narrow opening 1601. After the water flows through the narrow opening 1601, it accelerates and hits the flat barrier 17 to form a wrinkled flow.

[0035] Multiple bottom-mounted obstacles 18 are provided. These obstacles are irregularly shaped stones and are densely distributed on the bottom surface of the fifth ramp 11. When water flows through the bottom-mounted obstacles 18, bubbles are formed. These bubbles can be used to determine whether there are densely distributed obstacles under the water flow.

[0036] The above structure can highly simulate and intuitively demonstrate various dangerous water flow patterns, making it suitable for firefighter water rescue training, emergency rescue drills, and teaching demonstrations.

[0037] The above-described embodiments are merely illustrative of this utility model. Any equivalent embodiments made by those skilled in the art without departing from the technical features disclosed in this utility model, and without departing from the technical features of this utility model, shall still fall within the scope of the technical features of this utility model.
