DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0027] The present invention provides a river-type ecological restoration training device, such as Figures 1 to 6As shown, it includes a platform frame 1, an inner frame 2 is arranged on the inner side of the platform frame 1, and the top surfaces of the four corners of the inner frame 2 are fixedly connected to the inner top surface of the platform frame 1 by vertical rods 3, and multiple side panels 4 are fixed to the bottom of the two inner side surfaces of the inner frame 2, and a bottom plate 5 is correspondingly placed on the inner side of the inner frame 2, and the bottom surface of the bottom plate 5 is correspondingly fitted on the top surfaces of multiple side panels 4, and a threaded rod penetrating the side panels 4 is fixed on the bottom surface of the bottom plate 5, and a nut 6 is spirally sleeved on the bottom end of the threaded rod, and the top surface of the nut 6 is fitted with the bottom surface of the side panel 4, and the two sides of the front side of the bottom plate 5 are provided with collecting grooves 7, and the two collecting grooves are provided with collecting grooves 7. The grooves 7 are connected to each other through connecting pipes 8, and the top surfaces of the two collecting grooves 7 are flush with each other. A water storage barrel 9 is arranged at the bottom of the inner frame 2, and the top of the water storage barrel 9 corresponds to the bottom opening of the platform frame 1. The center of the bottom surface of the collecting groove 7 is connected to the water storage barrel 9 by a vertical pipe 10. The top end of the vertical pipe 10 is spirally clamped on the bottom surface of the collecting groove 7, and the bottom end of the vertical pipe 10 is inserted into the top of the water storage barrel 9. The front side of the bottom of the water storage barrel 9 is connected to a water inlet structure, and water is passed to the inside of the platform frame 1 through the water inlet structure. A supporting structure is installed on the top surface of the bottom plate 5, and a template 11 is installed on the top of the supporting structure. After the threaded rod on the bottom surface of the bottom plate 5 is aligned with the side plate 4, the bottom plate 5 corresponds to the top surface of multiple side plates 4 on the inner side of the inner frame 2, and the bottom end of the threaded rod penetrates the side plate 4, and the bottom plate 5 is fixedly installed on the inner side of the inner frame 2 by means of a screw fit between the nut 6 and the threaded rod. After the template 11 is defined by the supporting structure, the two collecting troughs 7 are respectively installed on the front and rear sides of the top of the inner frame 2, and the top of the vertical pipe 10 is screwed to the bottom of the collecting trough 7. At this time, the top of the water storage barrel 9 is correspondingly buckled at the bottom opening of the platform frame 1. At this time, the top of the water storage barrel 9 corresponds to blocking the bottom opening of the platform frame 1 to prevent water from leaking out of the platform frame 1, and a rubber pad is pasted on the outer side of the water storage barrel 9 to improve the effect of the water storage barrel 9 blocking the bottom opening of the platform frame 1.

[0028] After the water storage barrel 9 is installed at the bottom of the platform frame 1, the bottom end of the vertical pipe 10 is correspondingly inserted into the top of the water storage barrel 9 to ensure the connectivity between the collecting tank 7 and the water storage barrel 9. When the water level inside the platform frame 1 overflows the top opening of the collecting tank 7, the water inside the platform frame 1 enters the collecting tank 7, and the water inside the collecting tank 7 enters the water storage barrel 9 through the vertical pipe 10. At this time, the water inlet structure passes the water inside the water storage barrel 9 into the inside of the platform frame 1 to ensure the water circulation effect of the entire training device.

[0030] Various types of river scenes can be constructed through water circulation, templates 11 and supporting structures. Through the transformation process, the operator can display the effects of the river ecological restoration design plan before and after the transformation. Different river terrains, different bank slope types, different pollution source types, and different types of restoration measures can be combined at will. It can be closely combined with the prominent problems of real rivers, simulate boundary conditions such as hydraulics and terrain, and construct various forms of river scenes, solving the technical problems of traditional river devices that mainly display a single scene and cannot reflect the entire process of river transformation and ecological restoration. In addition, by adjusting the height of the supporting structure and matching the relevant templates 11, the water-passing components of ecological water conservancy structures can be constructed to conduct hydraulic experiments related to ecological water conservancy, solving the problem of inconvenient adjustment of water-passing structures in traditional water conservancy physical model experiments, and having better scalability.

[0031] Through water circulation, random combination of templates 11 and supporting structures, water flow regulation and other elements, more training projects can be developed to enrich the training content. A set of training equipment can complete more developable teaching and learning, making the output effect and utilization rate of the entire training device higher.

[0032] exist Figure 2 and Figure 3 In the embodiment, the collecting tank 7 is installed on the top of the inner frame 2, and the front and rear sides of the inner frame 2 are provided with protrusions supporting the collecting tank 7. A screw penetrating the protrusion is fixed to the bottom of the collecting tank 7, and a screw sleeve is spirally sleeved on the bottom end of the screw, and the bottom surface of the collecting tank 7 is fitted with the top surface of the inner frame 2. The collecting tank 7 is placed on the top of the protrusion of the inner frame 2. At this time, the screw fixed on the bottom of the collecting tank 7 passes through the protrusion, and the collecting tank 7 is fixed to the top of the inner frame 2 by the spiral effect of the screw sleeve and the bottom end of the screw, so as to prevent the collecting tank 7 from shaking on the inner side of the platform frame 1, so that the horizontal plane where the top surface of the collecting tank 7 is located remains unchanged.

[0033] exist Figures 1 to 6In the figure, the water inlet structure includes a water inlet pipe 12 and a U-shaped pipe 13. The bottom end of the water inlet pipe 12 is connected to the bottom surface of the front side end of the water storage barrel 9. A water pump is installed in the middle of the water inlet pipe 12. The top of the water inlet pipe 12 is connected to the center of the front side of the U-shaped pipe 13. The U-shaped pipe 13 is placed on the top of the platform frame 1 accordingly. Platforms corresponding to the U-shaped pipe 13 are fixed on both sides of the top surface of the platform frame 1. Drain pipes 14 are arranged on the inner sides of the side pipes on both sides of the U-shaped pipe 13. Faucets are installed on the drain pipes 14. A transverse pipe 15 connecting multiple drain pipes 14 is arranged on the inner side of the side pipe. Openings are arranged at both ends of the transverse pipe 15. The U-shaped pipe 13 drains water to the inside of the transverse pipe 15 through the drain pipe 14, and the transverse pipe 15 discharges the received water to the inside of the platform frame 1. The water pump has an external working power supply and a controller. After the water pump is controlled by the controller, the water pump uses the water inlet pipe 12 to extract water from the water storage barrel 9. The water in the water storage barrel 9 enters the U-shaped tube 13 through the water inlet pipe 12 until the two side tubes of the U-shaped tube 13 are filled with water. By opening the faucets on the multiple drainage pipes 14, the multiple drainage pipes 14 can discharge the water in the side tubes into the cross pipe 15, and the cross pipe 15 can discharge the water into the platform frame 1. Through the cooperation of the multiple drainage pipes 14, the amount of water discharged to the inside of the platform frame 1 can be changed in real time.

[0034] exist Figures 4 to 6 In the embodiment, the openings at both ends of the U-shaped tube 13 are spirally sleeved with a rotating sleeve 16, and the openings at the ends of the U-shaped tube 13 are correspondingly blocked by the rotating sleeve 16. A plunger 17 is passed through the center of the rotating sleeve 16, and a retaining ring 18 is spirally sleeved on the outer end of the plunger 17. A circular plate 19 is fixed on the inner end of the plunger 17, and the plunger 17 drives the circular plate 19 to slide inside the side tube of the U-shaped tube 13. After the circular plate 19 is inserted into the inside of the side tube of the U-shaped tube 13, the rotating sleeve 16 is spirally sleeved at the opening of the side tube through the outer end of the plunger 17, and the retaining ring 18 is spirally sleeved on the outer end of the plunger 17. The spiral effect of the retaining ring 18 and the plunger 17 limits the circular plate 19, so as to prevent the circular plate 19 from impacting the front end of the U-shaped tube 13, and facilitate the control of the length of the plunger 17 entering the side tube.

[0035] After the water in the water inlet pipe 12 enters the U-shaped tube 13, the impact force of the water drives the plug rod 17 to move through the circular plate 19, and the plug rod 17 gradually moves out from the inside of the side tube, and the circular plate 19 absorbs part of the impact force of the water to prevent the water from directly impacting the inside of the rotating sleeve 16. A plurality of spring pieces 20 are fixed in parallel at equal distances on the top and bottom of the inner wall of the side tube, and the distance between the inner ends of two relative spring pieces 20 is less than the diameter of the circular plate 19. A spring 21 is sleeved on the surface of the plug rod 17, and the front end of the spring 21 is connected to the circular plate 19, and the rear end of the spring 21 is in contact with the front side surface of the rotating sleeve 16. When the impact of water causes the circular plate 19 to approach the rotating sleeve 16, the circular plate 19 squeezes the spring 21 when moving inside the side tube, and the spring 21 is used to absorb the impact force of water on the circular plate 19. When the rear side of the circular plate 19 contacts the spring piece 20 inside the side tube, the impact force of water on the circular plate 19 is further absorbed by multiple spring pieces 20 until the circular plate 19 stops moving inside the side tube. The circular plate 19 and multiple spring pieces 20 can reduce the impact force of water on the rotating sleeve 16, thereby increasing the service life of the U-shaped tube 13.

[0036] exist Figure 3 , Figure 4 , Figure 7 and Figure 8 In the embodiment, the support structure includes a plurality of outer tubes 22 vertically fixed on the top surface of the bottom plate 5, an inner tube 23 is inserted inside the outer tube 22, a plurality of inner tubes 23 are paved with waterproof cloth 24 on top, and the surface of the waterproof cloth 24 is provided with through holes corresponding to the inner tubes 23, the bottom surface of the template 11 is laid flat on the top surface of the waterproof cloth 24, an insert 25 is fixed on the bottom surface of the template 11, and the bottom end of the insert 25 is correspondingly inserted into the top of the inner tube 23 through the through hole, and the template 11 and the top of the inner tube 23 clamp the waterproof cloth 24. The surface of the outer tube 22 is equidistantly provided with a plurality of screw holes, and a limiting rod 26 is screwed in the screw hole, and the inner side end of the limiting rod 26 is pressed and fitted on the surface of the inner tube 23. When the limiting rod 26 is twisted and moved out of the screw hole, the inner end of the limiting rod 26 is separated from the outer side of the inner tube 23, and the inner tube 23 is pulled up and down until the top of the inner tube 23 reaches a relative height, and the limiting rod 26 is twisted in the opposite direction until the inner end of the limiting rod 26 is pressed on the surface of the inner tube 23, and the inner tube 23 is limited. The template 11 is correspondingly plugged into the top of the inner tube 23 through the insertion tube 25. At this time, a through hole corresponding to the top of the inner tube 23 is opened on the surface of the waterproof cloth 24. At this time, the bottom end of the insertion tube 25 is correspondingly plugged into the top of the inner tube 23 through the through hole, and the waterproof cloth 24 is tightly sleeved on the surface of the insertion tube 25 through the through hole. At this time, the template 11 and the inner tube 23 cooperate to clamp the waterproof cloth 24, and the waterproof cloth 24 is made of a waterproof and highly plastic plastic material.

[0037] By limiting the spiral effect of the rod 26 and the screw hole, the lifting height of the top end of the inner tube 23 is controlled, so that the inner tube 23 can be extended and retracted up and down by 35 cm, and the extension accuracy is within 2.5 cm, so as to facilitate the adjustment of the real-time height of the template 11 inside the platform frame 1.

[0038] The inner tube 23 , the outer tube 22 and the bottom plate 5 are all made of stainless steel, the insert tube 25 is made of PVC (PolyvinylChloride) material, and the outer side surface of the bottom end of the insert tube 25 is tightly fitted with the inner wall of the inner tube 23 .

[0039] Working principle of the present invention:

[0040] Reference Figures 1 to 8 As shown, when the limiting rod 26 is twisted and the limiting rod 26 is moved out from the screw hole, the inner end of the limiting rod 26 is separated from the outer side of the inner tube 23, and the inner tube 23 is pulled up and down until the top of the inner tube 23 reaches a relative height, and the limiting rod 26 is twisted in the opposite direction until the inner end of the limiting rod 26 is pressed on the surface of the inner tube 23, and the inner tube 23 is limited. The template 11 is correspondingly plugged into the top of the inner tube 23 through the insert 25. At this time, a through hole corresponding to the top of the inner tube 23 is opened on the surface of the waterproof cloth 24. At this time, the bottom end of the insert 25 is correspondingly plugged into the top of the inner tube 23 through the through hole, and the waterproof cloth 24 is tightly sleeved on the surface of the insert 25 through the through hole. At this time, the template 11 and the inner tube 23 cooperate to clamp the waterproof cloth 24. The lifting height of the top of the inner tube 23 is controlled by the spiral effect of the limiting rod 26 and the screw hole, so as to facilitate the adjustment of the real-time height of the template 11 inside the platform frame 1.

[0041] After the threaded rod on the bottom surface of the bottom plate 5 is aligned with the side plate 4, the bottom plate 5 corresponds to the top surface of multiple side plates 4 on the inner side of the inner frame 2, and the bottom end of the threaded rod penetrates the side plate 4, and the bottom plate 5 is fixedly installed on the inner side of the inner frame 2 by means of a screw fit between the nut 6 and the threaded rod. After the template 11 is defined by the supporting structure, the two collecting troughs 7 are respectively installed on the front and rear sides of the top of the inner frame 2, and the top of the vertical pipe 10 is screwed to the bottom of the collecting trough 7. At this time, the top of the water storage barrel 9 is correspondingly buckled at the bottom opening of the platform frame 1. At this time, the top of the water storage barrel 9 corresponds to blocking the bottom opening of the platform frame 1 to prevent water from leaking out of the platform frame 1, and a rubber pad is pasted on the outer side of the water storage barrel 9 to improve the effect of the water storage barrel 9 blocking the bottom opening of the platform frame 1.

[0042] After the water storage barrel 9 is installed at the bottom of the platform frame 1, the bottom end of the vertical pipe 10 is correspondingly plugged into the top of the water storage barrel 9 to ensure the connection between the collection tank 7 and the water storage barrel 9. When the water level inside the platform frame 1 overflows the top opening of the collection tank 7, the water inside the platform frame 1 enters the collection tank 7, and the water inside the collection tank 7 enters the water storage barrel 9 through the vertical pipe 10. The water pump uses the water inlet pipe 12 to extract the water inside the water storage barrel 9, and the water inside the water storage barrel 9 enters the U-shaped tube 13 through the water inlet pipe 12 until the two side tubes of the U-shaped tube 13 are full of water. By opening the faucets on the multiple drainage pipes 14, it is convenient for the multiple drainage pipes 14 to discharge the water inside the side tubes into the inside of the transverse pipe 15, and it is convenient for the transverse pipe 15 to discharge the water into the platform frame 1. Through the cooperation of the multiple drainage pipes 14, the drainage volume discharged to the inside of the platform frame 1 can be changed in real time.

[0043] After the water inside the water inlet pipe 12 enters the U-shaped tube 13, the impact force of the water drives the plug rod 17 to move through the circular plate 19, and the plug rod 17 gradually moves out from the inside of the side tube. The circular plate 19 is used to absorb part of the impact force of the water to prevent the water from directly impacting the inner side of the rotating sleeve 16. When the impact of the water makes the circular plate 19 close to the rotating sleeve 16, the circular plate 19 squeezes the spring 21 when moving inside the side tube, and the spring 21 is used to absorb the impact force of the water on the circular plate 19. When the rear side of the circular plate 19 contacts the spring piece 20 inside the side tube, the impact force of the water on the circular plate 19 is further absorbed by multiple spring pieces 20 until the circular plate 19 stops moving inside the side tube. The circular plate 19 and multiple spring pieces 20 can reduce the impact force of water on the rotating sleeve 16, thereby improving the service life of the U-shaped tube 13.

[0044] Various types of river scenes can be constructed through water circulation, templates 11 and supporting structures. Through the transformation process, the operator can display the effects of the river ecological restoration design plan before and after the transformation. Different river terrains, different bank slope types, different pollution source types, and different types of restoration measures can be combined at will. It can be closely combined with the prominent problems of real rivers, simulate boundary conditions such as hydraulics and terrain, and construct various forms of river scenes, solving the technical problems of traditional river devices that mainly display a single scene and cannot reflect the entire process of river transformation and ecological restoration. In addition, by adjusting the height of the supporting structure and matching the relevant templates 11, the water-passing components of ecological water conservancy structures can be constructed to conduct hydraulic experiments related to ecological water conservancy, solving the problem of inconvenient adjustment of water-passing structures in traditional water conservancy physical model experiments, and having better scalability.

[0045] It should be pointed out that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit it.
