Description

Technical Field

[0001] The utility model belongs to the technical field of overtopping discharge measurement of seawall crest, and particularly relates to an automatic overtopping discharge measuring device for different cross-section tests in a flume. Background Art

[0002] Under the action of open-sea waves, the overtopping of a seawall is a complex hydrodynamics process. When the tide level outside the seawall is high and the waves are large, a part of seawater will cross the wave wall at the top of the seawall to form overtopping, which poses a threat to the buildings and human safety behind the seawall. Therefore, the overtopping discharge is one of the important factors for evaluating the safety of coastal structures such as seawalls, revetments, and breakwaters.

[0003] The existing Chinese invention with the application number 201710173980.9 discloses an automatic overtopping discharge measuring device for a seawall crest in a laboratory flume test. A seawall model is horizontally arranged in the flume, and a wave wall is arranged on the seawall model. The device is located behind the seawall model and includes a collecting trough, a collecting tank, a water level tracker, and a computer. The upper end of the collecting trough is vertically placed at the center of the top of the wave wall, and the lower end of the collecting trough is an outlet; the water inlet of the collecting tank is located below the outlet of the collecting trough; the water level tracker is fixed on the collecting tank and is used to measure the water level in the collecting tank; a data acquisition card is arranged in the computer, and the data acquisition card acquires the water level data in the water level tracker. The computer retrieves the water level data to generate a process curve of the water level changing with time, and performs display and storage. The measurement process of this invention does not require the intervention of staff and is automatically completed. The measurement result can truly reflect the overtopping discharge values generated by different sizes of waves in a wave train.

[0004] However, the above invention cannot fit tightly with wave walls of different shapes or angles, resulting in some water flowing out from the gap between the wave wall and the collecting trough and not flowing into the collecting tank, thereby leading to inaccurate measurement results and too single types of overtopping measured. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model further provides an automatic overtopping discharge measuring device for different cross-section tests in a flume.

Then, by rotating the first locking bolt, the water collecting tank is locked. Rubber strips can also be adhered to the surface of the water collecting tank to make the contact between the top end of the water collecting tank and the surface of the wave retaining wall closer, thereby reducing the water loss in overtopping measurement, making the measured value more accurate, and making the types of overtopping measured more diverse.

Detailed Embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described 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 creative efforts shall fall within the protection scope of the present utility model.

[0027] In the description of the present utility model, it should be understood that the terms "upper", "middle", "outer", "inner", etc. indicating orientation or position relationships are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0028] Example 1: In combination with Figures 1 to 3An automatic overtopping volume measuring device for different cross-section tests of a water tank is described. A seawall model 2 is arranged in the test water tank 1. A wave wall 3 is arranged on the seawall model 2. A collecting tank 5 is arranged on the seawall model 2. A water collecting tank 4 in contact with the wave wall 3 is rotatably connected to the top of the collecting tank 5. A flexible connecting belt 6 is arranged between the collecting tank 5 and the water collecting tank 4. First locking bolts 7 are symmetrically and threadedly connected to the collecting tank 5. A measuring box 8 is installed in the test water tank 1. A water level tracker 9 is installed in the measuring box 8 for measuring the water level in the measuring box 8. The water level tracker 9 is electrically connected to a computer.

[0029] Among them, the flexible connecting belt 6 is a water-impermeable soft surface connecting belt. One side of the flexible connecting belt 6 is installed together with the collecting tank 5, and the other side is installed together with the water collecting tank 4. The flexible connecting belt 6 is used to fill the gap between the collecting tank 5 and the water collecting tank 4. By rotating the water collecting tank 4 on the collecting tank 5, the top of the water collecting tank 4 is made flush with the top of the wave wall 3. Then the flexible connecting belt 6 will stretch or compress following the rotation of the water collecting tank 4, thereby preventing water from flowing out through the gap between the collecting tank 5 and the water collecting tank 4. The rotating top of the water collecting tank 4 can fit more closely to the top of the wave wall 3, and can fit more closely to wave walls 3 of different shapes or angles, preventing water from flowing out through the gap between the water collecting tank 4 and the wave wall 3. Then, by rotating the first locking bolt 7, the lower end of the first locking bolt 7 is brought into contact with the side surface of the water collecting tank 4, thereby locking the rotation angle of the water collecting tank 4 and preventing gaps from being generated when the water flow impacts, so that the overtopping volume of wave walls 3 of different shapes or angles can be measured, and the measured values are more accurate and the types of overtopping measured are more diverse.

[0030] Among them, the widths of the water collecting tank 4 and the collecting tank 5 are smaller than the width of the test water tank 1. There are gaps between the water collecting tank 4 and the collecting tank 5 and the test water tank 1, allowing water flow to pass through, which is convenient for the test personnel to observe the measurement situation of the overtopping test. The test water tank 1 is installed on the ground through a bracket. The bracket can level the plane of the test water tank 1 in the horizontal direction, reduce the influence of the slope on the test data, and thus improve the accuracy of the measured values.

[0031] In this application, a collection trough 5 is provided on the seawall model 2. A water collection trough 4 that contacts the wave-breaking wall 3 is rotatably connected to the top of the collection trough 5. A flexible connection belt 6 is provided between the collection trough 5 and the water collection trough 4. First locking bolts 7 are symmetrically and threadedly connected to the collection trough 5. A measurement box 8 is installed in the test water tank 1, and a water level tracker 9 is installed in the measurement box 8 for measuring the water level in the measurement box 8. The water level tracker 9 is electrically connected to a computer. The water level in the measurement box 8 is detected by the water level tracker 9, and then the data is displayed on the computer, so as to know the value of the overtopping volume measured. The water collection trough 4 rotatably connected to the top of the collection trough 5 is used to contact the top of the wave-breaking wall 3. When the angle or shape of the wave-breaking wall 3 changes, there is no need to reposition the collection trough 5. Only by rotating the water collection trough 4 to make the top of the water collection trough 4 contact the surface of the wave-breaking wall 3, the gap between the water collection trough 4 and the wave-breaking wall 3 can be reduced. Then, the water collection trough 4 is locked by rotating the first locking bolts 7. Rubber strips can also be adhered to the surface of the water collection trough 4 to make the contact between the top of the water collection trough 4 and the surface of the wave-breaking wall 3 closer, thereby reducing the water loss in overtopping measurement, making the measured value more accurate, and increasing the diversity of the overtopping types measured.

[0032] Embodiment 2: Based on Embodiment 1 and combined with Figure 3 it is described that the side surface of the water collection trough 4 is set as a sector.

[0033] In this application, by setting the side surface of the water collection trough 4 as a sector, the water collection trough 4 with a sector side surface can contact the collection trough 5 more closely when rotating, and the water collection trough 4 also fits more closely with the wave-breaking wall 3. The compression and stretching of the flexible connection belt 6 by the water collection trough 4 with a sector side surface during rotation are smoother, thereby extending the service life of the flexible connection belt 6, further reducing the gap between the water collection trough 4 and the wave-breaking wall 3, making the adjustment more convenient, and making the measured value more accurate.

[0034] Embodiment 3: Based on Embodiment 1 and combined with Figures 2 to 4 it is described that the collection trough 5 is a first collection platform 51. The first collection platform 51 is provided on the seawall model 2. The tail end of the first collection platform 51 is rotatably connected to a second collection platform 52, and a second locking bolt 53 is threadedly connected to the second collection platform 52.

[0035] Among them, the tail end of the second collection platform 52 is clamped on the measurement box 8, reducing the gap between the second collection platform 52 and the measurement box 8. Thus, when the water flow passes through, water loss can be reduced, and the connection between the second collection platform 52 and the measurement box 8 can also be made closer, preventing shaking when the water flow passes through. Therefore, the measured value is more accurate and the overall equipment is more stable.

[0036] In this application, the collection trough 5 is set as the first collection platform 51, and the first collection platform 51 is arranged on the seawall model 2. The tail end of the first collection platform 51 is rotatably connected to the second collection platform 52, and the second collection platform 52 is threadedly connected with a second locking bolt 53. The first collection platform 51 and the second collection platform 52 form a two-stage collection trough 5. By rotating the second collection platform 52, the second collection platform 52 can be made to fit more closely to the surface of the seawall model 2. Thus, the first collection platform 51 and the second collection platform 52 can be applied to different seawall models 2. The head end of the second collection platform 52 extends under the tail end of the first collection platform 51, enabling the second collection platform 52 to fully receive the overtopping waves flowing down from the first collection platform 51. As a result, the measured values are more accurate, applicable to different seawall models 2, and the types of overtopping waves measured are more diverse.

[0037] Example 4: Based on Example 3 and combined with Figure 3 it is described that a support frame 54 is slidably connected to the first collection platform 51, a first stabilizing seat 55 is installed on the support frame 54, and a third locking bolt 56 is threadedly connected to the first collection platform 51.

[0038] In this application, a support frame 54 is slidably connected to the first collection platform 51, a first stabilizing seat 55 is installed on the support frame 54, and a third locking bolt 56 is threadedly connected to the first collection platform 51. The first stabilizing seat 55 does not contact the surface of the seawall model 2, and there is a gap between them to prevent the first stabilizing seat 55 from damaging the structure of the seawall model 2 and affecting the test effect. Then, the first stabilizing seat 55 can be installed on both sides of the test water tank 1 through a suction cup or bolts to support the rear end of the first collection platform 51. After that, the first collection platform 51 is slid up and down on the support frame 54 to adjust the height of the first collection platform 51, and then the third locking bolt 56 is tightened to lock the first collection platform 51 on the support frame 54. Through the mutual cooperation between the first stabilizing seat 55 and the support frame 54, the first collection platform 51 can be more stable when the water flow passes through, with less shaking, improving stability. It can also adjust the distance between the first collection platform 51 and the seawall model 2, making the collection trough 4 fit more closely to the wave wall 3, further improving the accuracy of the measured overtopping values, and the types of overtopping waves measured are more diverse.

[0039] Example 5: Based on Example 4 and combined with Figure 4 it is described that two fourth locking bolts 57 are symmetrically threadedly connected to the second collection platform 52, and the same second stabilizing seat 58 is rotatably connected between the two fourth locking bolts 57.

[0040] In this application, a fourth locking bolt 57 is symmetrically thread - connected to the second collection table 52, and a same second stabilizing seat 58 rotates between the two fourth locking bolts 57. The second stabilizing seat 58 does not contact the surface of the seawall model 2, and there is a gap between them to prevent the second stabilizing seat 58 from damaging the overall structure of the seawall model 2 and affecting the test effect. Then, the second stabilizing seat 58 can also be installed on both sides of the test water tank 1 through a suction cup or bolts. After that, the fourth locking bolt 57 is tightened to make the second stabilizing seat 58 and the second collection table 52 stationary relative to each other, so that the second collection table 52 is more stable when there is water flow passing by, reducing the gap generated between it and the test water tank 1 due to shaking, preventing water loss, and thus making the measured over - wave value more accurate.

[0041] Example 6: Based on Example 1 or 2, it is further described as follows Figure 5 In the measuring box 8, a plurality of flexible wave - dissipating plates 10 are installed, and a plurality of wave holes 11 are formed on the flexible wave - dissipating plates 10. In this application, by installing a plurality of flexible wave - dissipating plates 10 in the measuring box 8 and forming a plurality of wave holes 11 on the flexible wave - dissipating plates 10, after the water flow passes through the second collection table 52 and enters the measuring box 8, the flexible wave - dissipating plates 10 can prevent the splashing of the water flow, and can also relieve the impact force of the water flow entering the measuring box 8, reducing the shaking of the water in the measuring box 8. The wave holes 11 can further weaken the splashing of the water, thereby preventing water loss. By reducing the shaking time of the water in the measuring box 8, the water level tracker 9 can more quickly measure the water level entering the measuring box 8, improving the measurement efficiency.

[0042] Example 7: Based on Example 6, it is further described as follows Figure 5 The wave holes 11 on adjacent flexible wave - dissipating plates 10 are arranged to be staggered with each other. In this application, by arranging the wave holes 11 on adjacent flexible wave - dissipating plates 10 to be staggered with each other, the mutually staggered wave holes 11 can further reduce the impact force of the water and further improve the measurement efficiency.

[0043] Example 8: Based on Example 6, it is further described as follows Figure 5 and Figure 6 A water outlet pipe 12 is installed on the measuring box 8. A rubber block 13 is slidably connected to the water outlet pipe 12. A slider 14 is installed on the rubber block 13. The slider 14 is slidably connected to the water outlet pipe 12, and a fifth locking bolt 15 is thread - connected to the slider 14.

[0044] In this application, a water outlet pipe 12 is installed on the measurement box 8. A rubber block 13 is slidably connected to the water outlet pipe 12. A slider 14 is installed on the rubber block 13. The slider 14 is slidably connected to the water outlet pipe 12. A fifth locking bolt 15 is threadedly connected to the slider 14. After loosening the fifth locking bolt 15, the rubber block 13 is driven by the slider 14 to move backward, so that the rubber block 13 no longer blocks the rectangular opening formed in the water outlet pipe 12, and the water in the measurement box 8 flows out from the rectangular opening. A return pipe is connected below the water outlet pipe 12. The water flowing out from below the water outlet pipe 12 can flow back into the test water tank 1 again through the action of the return pipe and the water pump for the overtopping experiment, thereby saving water resources, preventing test errors caused by water level changes, being more convenient to operate, and reducing labor intensity.

[0045] Embodiment 9: Based on Embodiment 8 and combined with Figure 6 it is described that when the rubber block 13 blocks the water outlet pipe 12, it is flush with the inner wall of the measurement box 8. By setting the rubber block 13 to be flush with the inner wall of the measurement box 8 when blocking the water outlet pipe 12, the rubber block 13 flush with the inner wall of the measurement box 8 will not damage the free volume inside the measurement box 8, can make the detection of the water level tracker 9 more standard, make the measured overtopping value more accurate, and the operation more convenient.

[0046] Embodiment 10: Based on Embodiment 1 and combined with Figure 1 and Figure 5 it is described that both the test water tank 1 and the measurement box 8 are made of transparent acrylic. By making both the test water tank 1 and the measurement box 8 made of transparent acrylic, it is convenient for experimenters to observe the water levels in the test water tank 1 and the measurement box 8, and can also observe the experimental changes during the overtopping process, thus being convenient for recording and the operation more convenient.

[0047] Working process:

[0048] When measuring the overtopping amount, the first stabilizing seat 55 and the second stabilizing seat 58 are installed on both sides of the test water tank 1. Then, the position of the first collection table 51 on the support frame 54 is adjusted. After moving to a suitable position, the second locking bolt 53 is tightened to keep the first collection table 51 and the support frame 54 stationary relative to each other. Then, the second collection table 52 and the second stabilizing seat 58 are rotated so that the second stabilizing seat 58 does not contact the surface of the seawall model 2. Then, the third locking bolt 56 and the fourth locking bolt 57 are tightened. Then, the water collection tank 4 is rotated so that the water collection tank 4 contacts the surface of the wave-breaking wall 3, and the first locking bolt 7 is tightened to lock the water collection tank 4. Therefore, the operation is convenient, it can be applied to wave-breaking walls 3 with different angles or shapes, the measured overtopping values are more accurate, and the measured overtopping types are more diverse.
