Description

Technical Field

[0001] The invention relates to the field of drainage and energy dissipation, and in particular to an assembled drainage and energy dissipation structure and a use method thereof. Background Art

[0002] Drainage energy dissipation refers to measures taken in drainage and water delivery systems to consume or disperse the energy of water flow drop to prevent or reduce the scouring damage caused by water flow to hydraulic structures and their downstream riverbeds, riverbanks, etc. These measures are particularly important in discharge structures and drop structures because they can effectively protect the structures from damage caused by the impact of water flow, and also help protect downstream rivers and canals from damage.

[0003] The methods of drainage energy dissipation include but are not limited to installing energy dissipation devices, adopting specific pipe structures, and using silencers and energy dissipators. The purpose of these measures is to reduce drainage noise and energy by controlling the movement of the fluid, thereby reducing the scouring effect of water flow on building structures and riverbeds. The locations where energy dissipation is required are generally set in drainage pipes, drainage ditches or drainage channels in the drainage and water supply system.

[0004] In the pipeline drainage system, the energy dissipation method of installing energy dissipation nodes or multi-stage energy dissipation elbows is often used. Although it can achieve a certain energy dissipation effect, the energy dissipation effect is poor and is only suitable for small-sized pipelines. In addition, the existing pipeline energy dissipation structure needs to be replaced at multiple locations during maintenance, which is not convenient for later maintenance; For example, the pipeline-type waterfall energy dissipation drainage structure proposed in patent CN219731905U has a complex energy dissipation structure and is difficult to maintain and repair in the later stage.

[0005] In drainage ditches or drainage channels, energy dissipation methods such as waterfalls and energy dissipation pools are commonly used. However, the waterfall structure is relatively fragile and easily damaged after long-term use, and it is difficult to repair in the later stage. The energy dissipation pool has low space utilization rate and occupies a large area of ​​land, which is also not conducive to later maintenance. For example, the energy dissipation structure for water conservancy projects proposed in patent CN111997007A has an energy dissipation effect, but the structure is complex and subsequent maintenance and repair are also difficult.

DETAILED DESCRIPTION

[0027] Embodiment 1: like Figure 1 and 2 As shown, an assembled drainage energy dissipation structure and a method of using the same include an energy dissipation pipe 1, a first overflow top 101 is provided at one end of the energy dissipation pipe 1, a plurality of water inlet holes 102 are provided on the surface of the first overflow top 101, a flow diversion plate 103 is provided inside the energy dissipation pipe 1, and a water outlet pipe 104 is provided inside the energy dissipation pipe 1 away from the first overflow top 101. The high potential energy water flow first contacts the first overflow top 101, undergoes primary energy dissipation, and then enters the energy dissipation pipe 1 through the water inlet holes 102, and then flows through the flow diversion plate 103 to complete secondary energy dissipation, and then the water flow continues to flow after passing through the flow diversion plate 103; The water outlet pipe 104 is located inside the energy dissipation pipe 1, and a flow diversion cavity is formed between the water outlet pipe 104 and the energy dissipation pipe 1. A connecting sleeve 105 is provided at one end of the water outlet pipe 104 close to the diversion plate 103, and a second overflow top 106 is provided at one end of the connecting sleeve 105 close to the diversion plate 103. The connecting sleeve 105 is provided with a plurality of water holes 107. The water flow passing through the secondary energy dissipation contacts the second overflow top 106, completes the third level of energy dissipation through the second overflow top 106, and then enters the flow diversion cavity to complete the fourth level of energy dissipation, and finally passes through the water holes 107 and is discharged through the water outlet pipe 104.

[0028] Through multi-stage energy dissipation, the energy dissipation effect of high potential energy water flow can be guaranteed.

[0029] The energy dissipation pipe 1, the first overflow top 101, the water inlet 102, the flow plate 103, the water outlet pipe 104, the connecting sleeve 105, the second overflow top 106 and the water hole 107 do not require on-site construction. After being processed and formed, they can be directly carried to the construction site for installation for efficient construction. In addition, the energy dissipation structure is integrated into one, and does not require multiple connections, so that disassembly and assembly are more convenient.

[0030] The energy dissipation pipe 1, the first overflow top 101, the flow plate 103, the water outlet pipe 104, the connecting sleeve 105 and the second overflow top 106 are preferably made of PET material, which has low material cost and is easy to process. In addition, the energy dissipation structure made of PET material has high strength, good toughness, good stability and good durability.

[0031] In the preferred solution, the first flood roof 101 is divided into two sections with different slopes, the end with a larger slope is connected to the energy dissipation pipe 1, and the end with a smaller slope is conical, first passing through the conical section for diversion, and then flowing into the water inlet 102; The second diffuser top 106 is conical, and the edge diameter of the second diffuser top 106 is larger than the diameter of the connecting sleeve 105. As required, the edge of the second diffuser top 106 can be bent upward to complete the flow diversion on one side while diverting the flow, further increasing the energy dissipation effect; A water leakage hole is provided at the center of the diverting plate 103, so that the water flow diverted through the diverting plate 103 will gather at the water leakage hole to complete the hedging, that is, diverting hedging, thereby further increasing the energy dissipation effect.

[0032] The water flow can be guided to the surroundings through the second overflow top 106, and then gathered in the connecting sleeve 105 through the water hole 107 after being diverted by the diversion cavity, completing the diversion and hedging for the second time, and the energy dissipation effect is better.

[0033] In the preferred embodiment, Figure 3 As shown, the outside of the energy dissipation pipe 1 is sleeved with a connecting pipe 2, and a retaining ring 3 is provided inside the connecting pipe 2. The outlet pipe 104 in the energy dissipation pipe 1 is close to the retaining ring 3. When in use, the energy dissipation pipe 1 can be placed in the connecting pipe 2. The outer diameter of the connecting pipe 2 can be determined according to the size of the connection at the installation position. The inner diameter of the connecting pipe 2 is adapted to the energy dissipation pipe 1, and the connection is more convenient through the connecting pipe 2.

[0034] For example, the end of the connecting pipe 2 is connected to the drain pipe through a pipe clamp in the prior art, and no additional connecting structure is required, and no heterosexual connection or switching is required. While ensuring the energy dissipation effect, it is easy to disassemble and assemble.

[0035] Embodiment 2: like Figure 1 , 2 , 4, 5, 10, 11 and 13, as shown, the circumferential surface of the connecting pipe 2 is provided with a limiting groove 201, and a mounting buckle 5 is provided in the limiting groove 201; The connecting pipe 2 is arranged in the drain ditch 4, and the drain ditch 4 refers to the existing drain ditch or drainage channel. The drain ditch 4 is provided with an installation groove 401, and the installation buckle 5 extends into the installation groove 401. The present application can not only be connected to the drain pipe, but also to the drain ditch 4, so as to adapt to different installation requirements, have better adaptability, and be easy to disassemble and assemble. It is convenient to replace after long-term use and easy to maintain.

[0036] In the preferred scheme, the mounting buckle 5 includes a bottom buckle arranged in the mounting groove 401, the bottom buckle extends to the inside of the limiting groove 201, the bottom buckle is connected to a top buckle, the top buckle extends to the inside of the limiting groove 201, and is connected in the limiting groove 201 by a combination of the bottom buckle and the top buckle. While clamping the connecting pipe 2, the connecting pipe 2 can be prevented from sliding relative to the bottom buckle and the top buckle. At the same time, the bottom buckle is located in the mounting groove 401, which can prevent the connecting pipe 2 from sliding relative to the drain ditch 4. When in use, the connecting pipe 2 is placed on the bottom buckle, and then the top buckle is connected to complete the fixing of the connecting pipe 2 and the installation of the energy dissipation pipe 1. Otherwise, it can be disassembled, which is convenient for the installation of the connecting pipe 2 in the drain ditch 4 and the drainage channel. No on-site construction is required, only unified modular installation is required, which is more efficient and more convenient for later maintenance.

[0037] In a further embodiment, the bottom buckle is a circular bottom buckle 501 or a square bottom buckle 504 or a heterogeneous bottom buckle, which is determined according to the actual situation of the actual drainage ditch 4 or drainage channel.

[0038] In a further embodiment, the top buckle is a first top buckle 502, and both ends of the first top buckle 502 are connected to the bottom buckle through a connecting piece; The top buckle or the second top buckle 505, one end of the second top buckle 505 is hinged to the bottom buckle through a hinge shaft 506, and the other end is connected to the bottom buckle through a connecting piece; When in use, the first top buckle 502 or the second top buckle 505 is selected according to actual conditions and needs, so as to have better adaptability.

[0039] When in use, the first top buckle 502, the second top buckle 505, the round bottom buckle 501, the square bottom buckle 504 or the opposite bottom buckle can be combined as needed.

[0040] In a further embodiment, the connecting member is a screw 503, which passes through the top buckle and is threadedly connected to the bottom buckle; The connecting piece may be a guide rod 507, which is connected to the bottom buckle and passes through the top buckle. The guide rod 507 may be tilted, vertical or curved as required, and it is necessary to ensure that it does not affect the placement of the top buckle. When in use, screws 503 or guide rods 507 can be selected as connecting pieces according to different needs.

[0041] Embodiment 3, like Figure 6 ,7 As shown in FIG8 , a slag removal mechanism is provided inside the drainage ditch 4 to handle large-sized impurities and prevent the energy dissipation pipe 1 from being blocked; The slag removal mechanism includes a buffer tank 402 disposed inside the drainage ditch 4, and a filter plate 7 is disposed inside the buffer tank 402. The filter plate 7 is used to isolate large impurities in the water flow to prevent the impurities from clogging the energy dissipation pipe 1. A fixing rod 601 is provided on the inner wall of the drainage ditch 4, and the fixing rod 601 is located between the filter plate 7 and the energy dissipation pipe 1. A fixing sleeve 602 is provided in the middle of the fixing rod 601, and a rotating shaft 603 is rotatably connected in the fixing sleeve 602. One end of the rotating shaft 603 is provided with a fan blade 604 located on the side of the fixing sleeve 602. One end of the rotating shaft 603 passes through the filter plate 7 and is provided with a rotating block 605. A plurality of connecting rods 606 are provided on the side of the rotating block 605, and the connecting rods 606 are away from the rotating block 605. A scraper 607 is provided at one end, and the rotating block 605 is connected to the rotating shaft 603 by bolts. In the process of drainage, water flows through the drainage ditch 4, and the fan blade 604 is affected by the water flow and rotates, thereby driving the rotating shaft 603 to rotate, thereby driving the rotating block 605, the connecting rod 606 and the scraper 607 to rotate. The scraper 607 can scrape away the impurities blocked by the filter plate 7, and in the process of the scraper 607 rotating, it will have a certain impact on the water flow, causing the water flow to be disturbed, and play an energy dissipation role; A slag removal port 403 connected to the buffer tank 402 is provided on the side of the drainage ditch 4. A collection chamber 404 is provided on the side of the drainage ditch 4. Impurities brought up by the scraper 607 can enter the collection chamber 404 through the slag removal port 403 and be collected. The collection chamber 404 can be dug into a pit or prefabricated collection box as needed, and the staff can handle the impurities regularly. like Fig. 9 As shown, an elastic rod 608 is connected between the connecting rod 606 and the scraper 607. The elastic rod 608 is preferably a rubber rod. The elastic rod 608 is bent. When in use, the elastic force of the elastic rod 608 enables the scraper 607 to always be close to the inner wall of the buffer groove 402 to ensure the impurity scraping effect.

[0042] Example 4 like Fig.15 , 16As shown in FIG. 17 , a fixed shaft 801 is further provided inside the drainage ditch 4. A central sleeve 802 is rotatably sleeved in the middle of the fixed shaft 801. A plurality of rotating plates 803 are provided along the circumference of the central sleeve 802. At least one rotating plate 803 is ensured to be located below the water surface. Side sleeves 804 are rotatably sleeved at both ends of the fixed shaft 801. A plurality of guide plates 805 are provided along the circumference of the side sleeve 804. A movable shaft 806 is rotatably connected to the outside of the fixed shaft 801. The movable shaft 806 is A driving tooth 807 is provided on the side away from the fixed shaft 801, and the driving tooth 807 is located between the central sleeve 802 and the side sleeve 804. A driven tooth 808 is provided on the side away from the fixed shaft 801. First crown gears 809 are provided at both ends of the central sleeve 802, and the first crown gears 809 mesh with the driving tooth 807. A second crown gear 810 is provided on the side of the side sleeve 804 close to the central sleeve 802, and the second crown gear 810 meshes with the driven tooth 808. The number of teeth of the active teeth 807 is smaller than that of the driven teeth 808, so as to ensure that the rotation of the rotating plate 803 can drive the guide plate 805 to rotate; When the rotating plate 803 rotates to the lowest position, the rotating plate 803 is located near the center of the water flow cross section. During drainage in the gutter or drainage channel, the water flow velocity near the center of the cross section is greater, and the potential energy is greater, while the water flow velocity near the edge of the cross section is lower. Therefore, the rotating plate 803 located at the center position will be subject to the maximum potential energy of the water flow, ensuring that the rotating plate 803 can rotate and drive the guide plate 805 to rotate.

[0043] The rotating plate 803 is a V-shaped plate, and the guide plate 805 is set at an angle. Under the influence of the V-shaped plate, the central water flow can be guided to both sides. The guide plate 805 can also guide the water flow to both sides, thereby avoiding excessive potential energy in the center of the water flow and achieving the purpose of energy dissipation. Since the potential energy in the center of the water flow is greater, the impact of the water flow on buildings and the like will be concentrated in the center, causing greater impact and damage. It is applied to guide the central water flow to both sides and generate turbulence to disperse the potential energy, thereby ultimately reducing the impact of the water flow on the building.

[0044] When in use, as the high-potential-energy water flow passes through, the central high-potential-energy water flow will push the rotating plate 803, thereby driving the central sleeve 802 to rotate, and then driving the first crown gear 809, the driving tooth 807, the driven tooth 808 and the second crown gear 810 to rotate in sequence, which can drive the side sleeve 804 and the guide plate 805 to rotate. When the rotating plate 803 is pushed, it will guide the flow while being pushed, generating turbulence, while the guide plate 805 rotates in the opposite direction and contacts the water flow during rotation, which will guide the flow while dissipating energy, guiding the central high-velocity water flow to the edge and generating turbulence, while dissipating energy and reducing the water flow in the center of the water flow, thereby reducing the impact on the building.

[0045] The angles of the rotating plate 803 and the guide plate 805 are determined according to the actual situation. Protective plates are fixed at both ends of the fixed shaft 801 , and the protective plates are arranged close to the inner wall of the drainage ditch 4 .

[0046] Embodiment 5: A method for using an assembled drainage and energy dissipation structure comprises the following steps: S1, put the energy dissipation pipe 1 into the connecting pipe 2, and put the end close to the water outlet pipe 104 first, until the energy dissipation pipe 1 abuts against the retaining ring 3; S2, determining the approximate installation position of the connecting pipe 2 at the drainage position; S3. Debug the installation position and calculate:
