Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of flood control experiment simulation, and specifically relates to an experimental equipment for simulating comprehensive flood control and drought resistance of a river basin. BACKGROUND

[0002] The experimental equipment for simulating comprehensive flood control and drought resistance of a river basin can simulate different meteorological conditions, topographic features and hydrological processes to evaluate the effectiveness of water resource management and flood control and drought resistance measures within the river basin and provide an important experimental platform for the research of flood control and drought resistance.

[0003] For example, the utility model with publication number CN217403757U discloses a flood control and treatment experiment simulation device, which comprises movable wheels, a connecting bottom plate, an experiment box and a wave generator. The top of the movable wheels is fixedly connected to the bottom of the connecting bottom plate, the bottom of the experiment box is fixedly connected to the top of the connecting bottom plate, and the right side of the top of the experiment box is fixedly connected to the bottom of the wave generator. The water level detection control assembly can be used to adjust the required water level, and the water level adjusting assembly can be used to increase or extract water in the experiment box. This solves the problem that the user needs to increase or reduce water for flood control and treatment detection according to different water levels during the experiment. The user's water level adjustment efficiency is low, and the user needs to constantly observe the water level during adjustment to prevent too much or too little water, which reduces the experimental efficiency of the flood control and treatment experiment simulation device. The device can automatically add water to adjust the water level.

[0004] The above device improves the experimental efficiency by setting the water level adjusting assembly. However, in the simulation of comprehensive flood control and drought resistance of a river basin, mud is an important experimental material. In actual flood events, water flow carries a large amount of sediment, which affects the flow structure and energy loss of flood water. By adding sediment in the experimental equipment, the suspension, settlement and transport law of sediment in flood water flow can be studied. However, after the experiment is completed, the device does not have a component for cleaning and collecting the experimental mud, which makes it inconvenient to recycle the used mud. If the mud is not recycled, new experimental mud needs to be purchased for each experiment, which wastes resources and increases experimental costs. Therefore, an experimental equipment for simulating comprehensive flood control and drought resistance of a river basin is proposed to solve the problems in the background art.

DETAILED DESCRIPTION

[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the range of protection of the utility model.

[0022] As Figures 1 to 5The utility model provides a kind of experimental equipment for simulating integrated flood control and drought resistance of river basin, including pedestal 1, one end of pedestal 1 is fixedly connected with pivot 2, pivot 2 is hinged with experimental box 3 outside, the two sides of the end of pedestal 1 away from pivot 2 are all hinged with hydraulic rod 4, movable connection has baffle 5 and collection tank 6 in the inside of experimental box 3, filter screen plate 7 is provided on the side of experimental box 3 close to pivot 2, one side of baffle 5 is fixedly connected with pull rod 8, movable connection has limit block 9 in the inside of baffle 5, the surface of the upper and lower ends of limit block 9 is all provided with inclined slot 10, movable connection has first toothed plate 11 in the inside of baffle 5, the two ends of first toothed plate 11 are all fixedly connected with round bar 12, the upper and lower ends of limit block 9 are all fixedly connected with spring piece 13, second toothed plate 14 is provided on the inner wall of the side of experimental box 3 close to pull rod 8.

[0023] Adopt the above scheme: by pulling baffle 5 to the outside of pedestal 1 moves, so that baffle 5 removes the sealing of pivot 2 and collection tank 6, to further facilitate the water in the inside of experimental box 3 is discharged, by the setting of filter screen plate 7, to facilitate the mud in water is intercepted, then, by the upper end of hydraulic rod 4 drives experimental box 3, so that experimental box 3 is inclined, to further make mud can move to the direction of filter screen plate 7 under the action of experimental box 3 inclined plane force and clean water thrust after injecting clean water, to further make mud is collected to collection tank 6, while, water is separated from mud by filter screen plate 7, to facilitate the mud after use is recycled, to further save experimental cost.

[0024] As Figure 1 And Figure 2 The experimental box 3 rotates with pivot 2 as the axis, the top end of the hydraulic rod 4 is hinged to the top of the experimental box 3, the second toothed plate 14 is fixedly connected to the side of the baffle 5 away from the pull rod 8, the second toothed plate 14 is made of rubber material, the collection tank 6 is provided with a filter screen identical to the filter screen plate 7 on one side, and the baffle 5 seals the middle part of the experimental box 3 and the collection tank 6 in the initial state.

[0025] Adopt the above scheme: the second toothed plate 14 is made of rubber material, which effectively controls the mud and water in the experimental box 3 during the simulation of integrated flood control and drought resistance of river basin, and the second toothed plate 14 abuts against the inner wall of the experimental box 3. Since the rubber material has good elasticity and sealing property, the second toothed plate 14 can fill the small gap between the baffle 5 and the inner wall of the experimental box 3, thereby improving the sealing effect of the baffle 5 on the experimental box 3 and preventing the mud and water from leaking during the experiment.

[0026] As Figure 4 And Figure 5As shown, the limiting block 9 penetrates the outer wall of the baffle 5 and extends to the inside of the pull rod 8, the circular rod 12 is movably connected in the inside of the chute 10, the first toothed plate 11 penetrates the outer wall of the baffle 5 and extends to the outside of the baffle 5, the first toothed plate 11 is connected with the second toothed plate 14 in the initial state, the inner wall of the baffle 5 is provided with a sliding groove matched with the first toothed plate 11, so that the first toothed plate 11 forms a linear motion pair in the sliding groove, and the limiting block 9 is elastically connected with the baffle 5 through the elastic sheet 13.

[0027] By the above scheme: the design of the elastic sheet 13, when the mud collection is completed, the baffle 5 needs to be reset, at this time, the operator pushes the base 1 towards the inside of the base 1, so that the baffle 5 drives the second toothed plate 14 to abut against the inner wall of the experimental box 3 again, then the pressing of the limiting block 9 is released, so that the limiting block 9 is reset under the action of the pulling force of the elastic sheet 13, then the circular rod 12 is driven by the chute 10 to move towards the second toothed plate 14, then the first toothed plate 11 is driven by the circular rod 12 to be connected with the second toothed plate 14 again, so that the position of the baffle 5 is fixed, and then the baffle 5 is sealed to the rotating shaft 2 again, so that the next simulation of the comprehensive flood control and drought resistance experiment of the river basin is facilitated.

[0028] The working principle and use process of the utility model: when the experiment is completed, at this time, the limiting block 9 is pressed towards the direction of the pull rod 8, so that the circular rod 12 slides in the inside of the chute 10, and because the first toothed plate 11 is limited by the inner wall sliding groove of the baffle 5, the circular rod 12 can only drive the first toothed plate 11 to shrink to the inside of the baffle 5 along the track of the chute 10, so that the first toothed plate 11 is disconnected with the second toothed plate 14, and at the same time, the limiting block 9 is completely shrunk to the inside of the pull rod 8, so that the baffle 5 is moved towards the outside of the experimental box 3 through the pull rod 8, and then the baffle 5 is disconnected with the experimental box 3 and the collecting box 6, then the water in the experimental box 3 flows out through the filter screen plate 7, and the mud contained in the water is blocked by the filter screen plate 7;

[0029] When the water inside the experimental box 3 is discharged, the operator issues a start command to the two hydraulic rods 4 through the remote control system (the control system issues a start command, which is a prior art and common knowledge), so that the hydraulic rods 4 push one end of the experimental box 3 to move upwards, and then the experimental box 3 rotates around the rotating shaft 2, and the bottom end of the hydraulic rod 4 also rotates around the hinge with the base 1 as the axis, when the experimental box 3 is rotated to the predetermined position by the hydraulic rod 4, the operator injects clean water into the experimental box 3, so that the clean water generates a pushing force on the mud remaining on the model and the bottom of the experimental box 3, and then the mud is pushed by the clean water to move towards the filter screen plate 7, so as to clean the mud inside the experimental box 3, finally, the mud is collected in the collecting box 6 under the action of the inclination of the experimental box 3, and the water is separated from the mud through the filter screen of the collecting box 6 and the filter screen plate 7, so as to collect the used mud, then the collecting box 6 is pulled outwards of the experimental box 3, so as to take out the collecting box 6, so as to recycle the mud, thereby saving the overall cost of the experiment.
