Description

Technical Field

[0001] The utility model belongs to the technical field of drainage structures, and in particular relates to a multi-stage cascading drop energy dissipation drainage system. Background Art

[0002] The cascading drop energy dissipation drainage system refers to a drainage system with multiple water retaining structures between the upper water inlet and the lower water outlet, making the original direct and vigorous flushing drainage method safer. The above-mentioned multiple water retaining structures are successively close to the water outlet in the horizontal and vertical directions, and are generally arranged in a diagonal manner. This is the meaning of the above-mentioned "cascading drop". On the other hand, the above-mentioned water retaining structures are at least 2, corresponding to the "multi-stage" feature.

[0003] In addition, drainage pipes need to be arranged between the water retaining structures. When appropriate water retaining components are arranged in the drainage pipes, the drainage pipes also have the function of retaining water and dissipating energy, making the drainage system more in line with the above-mentioned "multi-level energy dissipation" requirements.

[0004] For example, a Chinese utility model patent with authorization announcement number CN219731905U and authorization announcement date 2023.09.22 discloses a pipeline-type waterfall energy dissipation drainage structure, including a sludge grid well, the left inner wall of the sludge grid well is fixedly connected to a first water blocking plate, the right inner wall of the sludge grid well is fixedly connected to a second water blocking plate, the bottom inner wall of the sludge grid well is fixedly connected to a water blocking scale plate, the side surface of the sludge grid well is provided with a first water outlet, and the right surface of the sludge grid well is fixedly connected to an energy dissipation pipe.

[0005] The energy dissipation drainage structure in this utility model patent has the following general structural principles and advantages: water is initially dissipated in the silt grid well through the inlet and outlet with a drop, different water-blocking plates in the silt grid well cooperate with each other to dissipate energy of the water flow, and the stepped water dissipation pipe prevents the water flow from being eroded by the energy dissipation well due to the large drop. The outlet bend plate arranged at the outlet of the energy dissipation well allows the outflowing water to hit the baffle and then be sent into the air by the outlet bend plate, so that the water flow dissipates energy again in the air before flowing into the river, thereby preventing the water flow from directly flowing into the river and causing erosion of the river bank due to incomplete energy dissipation.

[0006] However, in actual use, the energy dissipation and drainage structure still has at least the following two shortcomings, which are also the technical problems to be solved by the utility model, namely:

[0007] First, its direct energy dissipation structures such as water blocking plates and baffles can only be fixed on 1-3 sides when installed in the well, so there is a problem of low fixing strength, which is relatively easy to be impacted and fall off by water flow, and eventually lose the energy dissipation function;

[0008] Second, the spiral blade structure frequently expands and contracts when dissipating energy, which will continuously wear and impact the energy dissipation pipe, shortening the effective service life of the energy dissipation pipe. After the energy dissipation pipe is broken, it needs to be completely replaced, which is relatively costly.

[0009] So to sum up, there is an urgent need for a new multi-stage, cascading drop energy dissipation drainage system with relatively high installation stability in the direct energy dissipation part and spiral blades that are not easy to damage the connecting pipes during use. Utility Model Content

[0010] The utility model provides a multi-stage cascading drop energy dissipation drainage system, which can be arranged on the drainage well by means of a manhole cover, a drainage pipe, a spiral sheet, an energy dissipation cavity unit, a four-sided fixed energy dissipation plate unit, a barrier frame unit, and a dual-purpose pipeline unit for removing impurities and draining, so that: 1. the four-sided fixed energy dissipation plate unit has sufficient installation stability and is not easily washed away and dropped by the water flow, and the water-blocking and energy-dissipating effect is effective for a long time; 2. the spiral sheet is not easy to collide with or wear the drainage pipe, and the barrier frame unit is a wearing part, and the replacement cost is relatively low.

[0011] The technical solution adopted by the utility model to solve the above-mentioned problems is: a multi-level cascade drop energy dissipation drainage system, the structure of which includes a drainage well, a well cover, a drainage pipe, and a spiral sheet, and also includes an energy dissipation cavity unit arranged on the drainage pipe, a four-sided fixed energy dissipation plate unit arranged in the energy dissipation cavity unit, a barrier frame unit arranged in the drainage pipe and provided with the spiral sheet inside, and a debris removal and drainage dual-purpose pipe unit arranged on the energy dissipation cavity unit.

[0012] A further preferred technical solution is that the energy dissipation chamber unit includes a box body, a cover plate arranged on the box body, an inlet and outlet hole arranged on the box body and used to install the drain pipe, and a dual-purpose opening arranged on the cover plate and used to install the debris removal and drainage dual-purpose pipe unit.

[0013] A further preferred technical solution is that the energy dissipation cavity unit further includes a reinforcing plug plate arranged on the outer side of the box body.

[0014] A further preferred technical solution is that the four-side fixed energy dissipation plate unit includes a water baffle plate with two side edges and a bottom edge arranged on the inner side surface of the box body, and a fixing rod arranged on the upper surface of the water baffle plate and used to connect the cover plate.

[0015] A further preferred technical solution is that the four-side fixed energy dissipation plate unit further includes vertical reinforcement rods, the upper and lower ends of which are respectively arranged on the cover plate and the box body and used to support the back water surface of the water retaining plate.

[0016] A further preferred technical solution is that: the four-side fixed energy dissipation plate unit also includes a water debris passage opening arranged on the bottom edge of the water retaining plate.

[0017] A further preferred technical solution is that the barrier frame unit includes a circular ring for supporting the spiral blade in the direction of water flow, and a barrier support rod arranged on the circular ring and located between the spiral blade and the drain pipe.

[0018] A further preferred technical solution is that 3-4 blocking support rods are provided on the ring.

[0019] A further preferred technical solution is that the dual-purpose pipeline unit for impurity removal and drainage includes a dual-purpose vertical pipe arranged on the dual-purpose opening, and a perforated cover plate arranged at the upper end opening of the dual-purpose vertical pipe.

[0020] A further preferred technical solution is that the dual-purpose pipeline unit for removing impurities and draining water also includes a reinforcing plug rod arranged on the outer annular surface of the dual-purpose vertical pipe. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0036] As attached Figure 1-9 As shown, a multi-stage cascade drop energy dissipation drainage system comprises a drainage well 11, a well cover 12, a drainage pipe 13, and a spiral sheet 14, and also comprises an energy dissipation cavity unit 1 arranged on the drainage pipe 13, a four-side fixed energy dissipation plate unit 2 arranged in the energy dissipation cavity unit 1, a barrier frame unit 3 arranged in the drainage pipe 13 and provided with the spiral sheet 14 inside, and a dual-purpose pipeline unit 4 for impurity removal and drainage arranged on the energy dissipation cavity unit 1.

[0037] In this embodiment, the bottom of the drainage well 11 is opened for installing the first section of the drainage pipe 13. The spiral blade 14 is made of elastic plastic or elastic stainless steel, and is used to dissipate energy of the water flow through its own expansion and contraction deformation.

[0038] Among them, the main structure of the energy dissipation cavity unit 1 is 6 plates at the top, bottom, left, right, front and back. The water flow impacts and swirls in the energy dissipation cavity unit 1, which already has a basic and relatively low energy dissipation effect.

[0039] In addition, each of the energy dissipation cavity units 1 is provided with a four-sided fixed energy dissipation plate unit 2, and each of the energy dissipation cavity units 1 is provided with a dual-purpose pipe unit 4 for removing impurities and draining water. The structural and functional characteristics of the four-sided fixed energy dissipation plate unit 2 are: stable installation, direct water flow blocking, and high energy dissipation strength. The structural and functional characteristics of the dual-purpose pipe unit 4 for removing impurities and draining water are: vertical setting, upper end exposed, reinforcement of the entire drainage system, upward hooking or suction for removing impurities, and downward auxiliary drainage.

[0040] In addition, the material of the barrier frame unit 3 is high-strength rubber or corrosion-resistant metal, and multiple ones are arranged in a single drain pipe 13, which are supported against each other, and their number and positions correspond one-to-one to the spiral blades 14, ensuring that the spiral blades 14 have the dual advantages of deformation energy dissipation and not touching the drain pipe 13.

[0041] Finally, there are two main ways to install the drainage system:

[0042] First, as attached Figure 2 As shown, the whole is installed in the foundation a, the manhole cover 12 and the upper end of the impurity removal and drainage dual-purpose pipe unit 4 are exposed on the upper surface of the foundation a, and the outlet of the last section of the drainage pipe 13 is exposed on the side of the foundation a, so that the above-mentioned stacking height difference and energy dissipation drainage effect can be effectively achieved;

[0043] Second, as attached Figure 3 As shown, the whole is installed on the high platform plate b, wherein the drainage pipe 13, the energy dissipation cavity unit 1 and the impurity removal and drainage dual-purpose pipe unit 4 can be further reinforced and connected to the support column c, so as to obtain the stacking height difference and energy dissipation and drainage effect.

[0044] The energy dissipation chamber unit 1 includes a box body 101, a cover plate 102 arranged on the box body 101, an inlet and outlet hole 103 arranged on the box body 101 and used to install the drainage pipe 13, and a dual-purpose opening 104 arranged on the cover plate 102 and used to install the debris removal and drainage dual-purpose pipeline unit 4.

[0045] In this embodiment, the box body 101 is composed of four side panels and a bottom panel, which are integrally formed. The cover plate 102 is screwed to the box body 101 or is directly placed thereon and is pressed and fixed by the foundation a.

[0046] There are two water inlet and outlet holes 103, which are symmetrically located and correspond to two drainage pipes 13, respectively, so that water can effectively enter and exit the box 101. The dual-purpose opening 104 is connected and fixed with the dual-purpose pipe unit 4 for impurities removal and drainage with high strength and is fully sealed, so that: if the drainage system is used in the foundation a, it is prevented from generating gaps there and leaking into the soil; if the drainage system is used on the high platform plate b, it is ensured that the dual-purpose pipe unit 4 for impurities removal and drainage can suspend and fix the energy dissipation cavity unit 1 to prevent the latter from falling.

[0047] The energy dissipation cavity unit 1 further includes a reinforcing plug plate 105 arranged on the outer side of the box body 101 .

[0048] In this embodiment, when the drainage system is used in foundation a, the reinforcing plug plate 105 can be inserted into the soil layer to reinforce the entire energy dissipation cavity unit 1. When the drainage system is used on the high platform plate b, the reinforcing plug plate 105 can be connected to the support column c, which also reinforces the energy dissipation cavity unit 1 and the entire drainage system.

[0049] The four-side fixed energy dissipation plate unit 2 includes a water baffle 201 with two side edges and a bottom edge arranged on the inner side of the box body 101 , and a fixing rod 202 arranged on the upper surface of the water baffle 201 and used to connect the cover plate 102 .

[0050] In this embodiment, the water retaining plate 201 is fixed at all four sides, so it has sufficient water flow resistance. The gap left by the fixing rod 202 is an effective drainage position.

[0051] Accordingly, the water retaining and energy dissipation effect of the four-side fixed energy dissipation plate unit 2 is generally inversely proportional to the degree of drainage smoothness, and the length and number of the fixing rods 202 can be set as needed. For example, when the water retaining and energy dissipation effect needs to be relatively large, the fixing rods 202 can be set short and more, so that the water retaining plate 201 is larger in size and the effective drainage area is smaller in size.

[0052] The four-side fixed energy dissipation plate unit 2 further includes a vertical reinforcement rod 203 , the upper and lower ends of which are respectively arranged on the cover plate 102 and the box body 101 and used to support the back water surface of the water retaining plate 201 .

[0053] In this embodiment, the length of the vertical reinforcing rod 203 is the distance between the lower surface of the cover plate 102 and the inner bottom surface of the box body 101 , and it abuts against the water retaining plate 201 to prevent the water retaining plate 201 from being separated from the box body 101 .

[0054] The four-side fixed energy dissipation plate unit 2 further includes a water debris passage opening 204 arranged on the bottom edge of the water retaining plate 201 .

[0055] In this embodiment, the position of the dual-purpose opening 104 corresponds to the upstream side of the water flow of the water baffle 201, where most of the debris in the water is intercepted, so that the dual-purpose debris removal and drainage pipe unit 4 has sufficient suction and hooking debris removal effects.

[0056] However, debris in the water may also be carried by the water flow to the other side of the water retaining plate 201. Figure 4 , which is the right side of the figure. At this time, the water debris passage opening 204 allows debris to pass through, ensuring that the debris removal and drainage dual-purpose pipeline unit 4 is more thoroughly cleared.

[0057] Of course, even if some debris remains in the box 101, it does not affect the overall drainage effect and energy dissipation effect of the drainage system. Similarly, even if some debris is always entangled on the spiral sheet 14, it does not affect its deformation energy dissipation function and drainage effect.

[0058] The barrier frame unit 3 includes a ring 301 for supporting the spiral sheet 14 in the direction of water flow, and a barrier support rod 302 disposed on the ring 301 and located between the spiral sheet 14 and the drain pipe 13 .

[0059] In this embodiment, the single section of the drain pipe 13 can be a straight pipe or a bent pipe. The length of a single barrier frame unit 3 and the outline length of a single spiral sheet 14 are both significantly smaller than the length of the drain pipe 13 .

[0060] Therefore, a plurality of the barrier frame units 3 need to be stacked together with the spiral sheets 14 in the drain pipe 13 for use, that is, the barrier support rods 302 support the ring 301 of the previous barrier frame unit 3 .

[0061] On the other hand, the barrier frame unit 3 and the spiral sheet 14 both have a certain bending elasticity, so after the two are plugged together, they can be used at the bend of the drain pipe 13 and can be plugged in and out smoothly.

[0062] Three to four blocking support rods 302 are disposed on the circular ring 301 .

[0063] In this embodiment, the 3-4 blocking support rods 302 are evenly spaced and arranged in a circular arrangement on the ring 301 to prevent the spiral blades 14 from colliding with and wearing the drain pipe 13 .

[0064] In addition, the inner diameter of the circular ring 301 is smaller than the outer diameter of the spiral sheet 14 , so that the spiral sheet 14 does not pass through the circular ring 301 .

[0065] The dual-purpose pipeline unit 4 for impurity removal and drainage includes a dual-purpose vertical pipe 401 disposed on the dual-purpose opening 104 , and a perforated cover plate 402 disposed at the upper end opening of the dual-purpose vertical pipe 401 .

[0066] In this embodiment, the length of the dual-purpose vertical pipe 401 depends on the distance between the corresponding energy dissipation cavity unit 1 and the ground or the high platform plate b, and it is sufficient to ensure that the perforated cover plate 402 is exposed.

[0067] In addition, when the perforated cover plate 402 is not opened, the dual-purpose pipe unit 4 for removing impurities and draining water is used to drain water downward, and its function is similar to that of the drainage well 11. When the drainage speed of the drainage system drops significantly, the perforated cover plate 402 needs to be opened, and the impurities intercepted in the energy dissipation cavity unit 1 are hooked or sucked upward, so that the energy dissipation and drainage function becomes effective again.

[0068] On the other hand, the debris entangled and accumulated on the spiral blade 14 will generally be carried into the energy dissipation cavity unit 1 downstream thereof by the impact of the water flow. The amount of debris thereon is generally relatively small and will not cause a significant reduction in the drainage speed of the drainage system. The debris thereon does not need to be removed specifically.

[0069] The dual-purpose pipeline unit 4 for removing impurities and draining water further includes a reinforcing plug rod 403 arranged on the outer annular surface of the dual-purpose vertical pipe 401 .

[0070] In this embodiment, the role of the reinforcing rod 403 is similar to that of the reinforcing plate 105, which can be inserted into the soil layer or connected to the support column c, thereby directly reinforcing the dual-purpose pipe unit for debris removal and drainage 4 and indirectly reinforcing the entire drainage system.

[0071] Finally, the outlet of the drainage system is the last section of the drainage pipe 13. At this time, the water flows through multiple stages of energy dissipation and is discharged at a relatively slow speed to avoid significant erosion of the soil layer at the outlet, or to avoid significant impact on pedestrians and vehicles passing by the outlet.

[0072] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the utility model.
