Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting and rescue, in particular to an inner flood and river water flow simulation facility. Background Technique

[0002] Inner flood and river water flow refer to a typical geological disaster caused by the collapse of bank embankments, dikes, etc. due to water flow scouring, especially during floods; bank collapse of the river bank is the result of the interaction between river water flow and the soil body of the river bank. Man-made dams, blockers of different structures and shapes in the river, as well as blockers formed by garbage blockages, will change the flow direction of the water body to form an internal reflux area, greatly increasing the difficulty of fire fighting and rescue;

A water outlet is arranged on the side of the first accommodation space far from the inlet, and a second flow valve is arranged at the water outlet. By adjusting the flow rates of the inlet and the water outlet through the first flow valve and the second flow valve, the flow scouring of floods at different water levels can be simulated, increasing the authenticity and diversity of the experiment;

[0004] However, the above-mentioned flume test device for simulating external floods and inner floods still has the following problems in actual use: Although the scouring effect of different water level flows is achieved through the annular experimental device, in the actual rivers of external floods and inner floods, in addition to the scouring of the water flow, the water flow will also be affected by man-made objects such as dams and blockers of different structures. And the rescue methods are different when facing man-made dams and blockers. It is difficult to comprehensively simulate and demonstrate different types of rescue situations only through the annular experimental device, thereby reducing the cognitive effect of effectively coping with rescue situations.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0032] Please refer to Figures 1-7 , the present utility model provides the following technical solutions:

[0033] Embodiment 1: To solve the problems existing in the use of the existing facility body 4, therefore, through the following technical solutions in this embodiment, the waterlogging and river water flow simulation facility includes a bearing base 1 and a water storage cavity 2 opened inside the bearing base 1, and a suction water pump 3 is fixedly installed inside the water storage cavity 2; it also includes: a facility body 4 is fixedly installed on the top surface of the bearing base 1, and a partition cross plate 5 is fixedly installed below the interior of the facility body 4, and the right side inside the facility body 4 is clamped and slidably connected to the outer end of the water retaining vertical plate 6; wherein, a water inlet slot hole 7 is opened on the left side inside the bottom surface of the facility body 4, and a drainage slot opening 8 is opened on the right side inside the bottom surface of the facility body 4; wherein, the water inlet slot hole 7 on the left side inside the bottom surface of the facility body 4 is connected through to the top end of the water inlet pipe 19, and the bottom end of the water inlet pipe 19 is connected through to the suction water pump 3 inside the bearing base 1;

[0034] The length of the facility body 4 is greater than the length of the partition cross plate 5, and the gap between the left end of the partition cross plate 5 and the facility body 4 is connected through to the opened water inlet slot hole 7, and the water flow is guided to the gap between the left end of the partition cross plate 5 and the facility body 4 through the water inlet slot hole 7, and the water flow sucked by the facility body 4 is blocked by the partition cross plate 5 and the water retaining vertical plate 6 on the right side; the bottom end of the partition cross plate 5 is attached to the top surface of the right end of the partition cross plate 5 inside the facility body 4, and the rising of the slidably clamped partition cross plate 5 enables the water body above the partition cross plate 5 to flow to the drainage slot opening 8 opened on the right side of the bottom surface of the facility body 4, and the water body is discharged back into the water storage cavity 2 inside the bearing base 1 through the drainage slot opening 8;

[0035] A sound insulation and noise reduction layer is laid on the inner wall of the water storage cavity 2 opened inside the bearing base 1 to reduce the noise generated when the suction water pump 3 inside the water storage cavity 2 is operating, and a rubber sealing strip is provided between the top end of the bearing base 1 and the bottom end of the facility body 4 to reduce the noise during the operation of the bearing base 1 and the facility body 4, improve the sealing effect, and avoid interference of noise to the simulation demonstration operator;

[0036] Such as Figures 2-3 and Figure 6As shown in the figure, during the process of using the facility body 4 for simulation, first, water is injected into the water storage cavity 2 opened inside the bearing base 1, and then the water body is sucked through the suction water pump 3 and the connected inlet pipe 19, so as to convey the sucked water body upward through the inlet pipe 19, and the water flow is conveyed by the inlet pipe 19 into the inlet slot 7 opened on the left side inside the bottom surface of the facility body 4 connected through;

[0037] Furthermore, after the water body enters the facility body 4 and is stored, and when the water level is higher than the partition cross plate 5 below the facility body 4, it is blocked by the water retaining vertical plate 6 slidably arranged at the right end of the facility body 4, so that the water body can be stored above the partition cross plate 5. At the same time, by manually controlling the distance between the bottom end of the water retaining vertical plate 6 and the top surface of the partition cross plate 5, the water body can be discharged to the right side of the facility body 4 through the gap, and the discharged water body flows through the drainage slot 8 opened below it, so as to return to the water storage cavity 2 inside the bearing base 1 again, thereby achieving the effect of reciprocating cycle and avoiding waste of water resources;

[0038] At the same time, the inner wall of the water storage cavity 2 opened in the bearing base 1 is provided with a sound insulation and noise reduction layer to reduce the noise generated by sucking water through the suction water pump 3. At the same time, the rubber sealing strips arranged at the top end of the bearing base 1 and the bottom surface of the facility body 4 fill the gap between the two to reduce the noise during the operation of the bearing base 1 and the facility body 4 and improve the sealing effect;

[0039] Embodiment 2: In order to solve the problems existing in the use of the existing facility body 4, therefore, in this embodiment, through the following technical solutions, pier simulators 9, dam simulators 10, sluice hole simulators 11 and width simulators 12 are slidably arranged at equal distances inside the facility body 4, and clamping limit strips 13 are fixedly installed at the front and rear ends of the pier simulators 9, dam simulators 10, sluice hole simulators 11 and width simulators 12, and the pier simulators 9, dam simulators 10, sluice hole simulators 11 and width simulators 12 are slidably clamped inside the facility body 4 through the clamping limit strips 13 at the front and rear ends;

[0040] The dam simulator 10 inside the facility body 4 is arranged in a right trapezoidal structure. A simulated sluice opening 17 is provided at the center of the bottom surface of the sluice opening simulator 11. A water-blocking grille 15 is slidably attached to the left side of the sluice opening simulator 11. The top end of the water-blocking grille 15 is connected to the top surface of the sluice opening simulator 11 through a contact spring 18, so as to simulate a water conservancy sluice station in a river channel through the lifting of the water-blocking grille 15 in cooperation with the sluice opening simulator 11; the width simulator 12 is arranged in a right triangle structure distributed front and back. The top surface of the width simulator 12 is rotatably connected to the outer end of the positioning cross plate 16, and the width simulator 12 is rotated through the positioning cross plate 16 to simulate waterlogging and river channels that change from narrow to wide and from wide to narrow under different conditions;

[0041] As Figure 1 , Figures 4-5 , Figure 7 As shown, when it is necessary to simulate the influence of different dams, arresters, etc. on water flow in the middle of a river channel inside the facility body 4, the pier simulator 9, dam simulator 10, sluice opening simulator 11, and width simulator 12 are snap-fitted and installed above the inside of the facility body 4 through the snap-fitting limit strip 13, and are pressed downward to fit against the top surface of the partition cross plate 5 according to human needs, so as to simulate the influence of different dams, arresters, etc. on water flow in the middle of a river channel and the demonstration of rescue;

[0042] Furthermore, for example, when the pier simulator 9 enters the water through the limit bottom plate 14 rotatably connected to the bottom surface, when the flowing water body encounters the pier simulator 9 placed at different angles, water flow will form backflow areas with different angles and sizes on the front and back sides behind the pier simulator 9. When the dam simulator 10 crosses the water flow, its inclined surface and vertical surface will also cause water flow to form backflow areas with different sizes and flow velocities near the dam simulator 10. The water flows in these backflow areas impact each other, making it difficult for a person falling into the water to escape by rotating in this area. Therefore, the facility body 4 simulates the flood conditions of different river channels to simulate rescue for this situation;

[0043] Based on the simulation solution disclosed in Embodiment 2, which is to conduct simulation inside the facility body 4 through the pier simulator 9, the dam simulator 10, the sluice opening simulator 11, and the width simulator 12, another simulation solution is disclosed in this embodiment. The pier simulator 9, the dam simulator 10, the sluice opening simulator 11, and the width simulator 12 are slidably arranged at equal distances inside the facility body 4. In the initial state, the pier simulator 9, the dam simulator 10, the sluice opening simulator 11, and the width simulator 12 are engaged with the upper part inside the facility body 4 through the protrusions at the outer ends of the clamping limit strips 13. After the pier simulator 9, the dam simulator 10, the sluice opening simulator 11, and the width simulator 12 descend, they are attached to the top surface of the partition cross plate 5. Moreover, a limit bottom plate 14 is rotatably arranged at the bottom surface of the pier simulator 9, which facilitates the rotation of the pier simulator 9 to simulate piers blocking water in different directions.

[0044] Main magnetic attraction blocks 20 are fixedly installed at the bottom surfaces of the pier simulator 9, the dam simulator 10, the sluice opening simulator 11, and the width simulator 12. A secondary magnetic attraction block 21 is fixedly installed inside the partition cross plate 5. Through the attraction between the secondary magnetic attraction block 21 and the main magnetic attraction block 20, the situations where the pier simulator 9, the dam simulator 10, the sluice opening simulator 11, and the width simulator 12 float and displace when impacted by water flow are avoided.

[0045] As Figures 4-5 shown, the pier simulator 9, the dam simulator 10, the sluice opening simulator 11, and the width simulator 12 in the facility body 4 can be arranged at equal distances, so as to be engaged with the upper part inside the facility body 4 through the protrusions of the clamping limit strips 13 at the front and rear ends. Or the required simulator, such as the dam simulator 10, can be separately arranged inside the facility body 4 through the clamping limit strip 13. And the left - right position of the dam simulator 10 inside the facility body 4 can be adjusted according to actual usage requirements. Thus, during the process of simulating floods through the dam simulator 10, visual occlusion will not occur, and the demonstration can be made more intuitive. The main magnetic attraction block 20 arranged at the bottom surface of the dam simulator 10 and the secondary magnetic attraction block 21 inside the partition cross plate 5 attract each other to prevent the situation of floating displacement when impacted by water flow.

[0046] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
