Description

Technical Field

[0001] This utility model relates to the field of trench drainage technology, specifically a drainage structure for substation transmission lines. Background Technology

[0002] A substation is a place in a power system that transforms voltage and current, receives electrical energy, and distributes electrical energy. The substation in a power plant is a step-up substation, whose function is to step up the electrical energy generated by the generator and feed it into the high-voltage power grid. With the development of science and technology in my country, the development of my country's power industry is getting better and better, and various power equipment and power buildings have emerged. Substations have played a significant role in people's daily lives and industrial production. There are also more and more protection measures in substations, including a drainage structure for substation transmission lines.

[0003] Existing drainage systems mostly use filters to prevent debris from entering the drain. However, this can lead to excessive debris buildup on top of the filters, reducing drainage efficiency and requiring manual cleaning. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a drainage structure for substation transmission lines. This solves the technical problem that current drainage structures mostly use filter screens to prevent garbage from entering the drainage ditch, which may result in excessive garbage on the top of the filter screen, leading to a decrease in drainage efficiency and requiring personnel to lift and clean it.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: A drainage structure for substation transmission lines is designed, comprising:

[0006] A drain pipe, wherein a filter screen is provided at the top inlet of the drain pipe;

[0007] Cleaning mechanism, the cleaning mechanism comprising:

[0008] A turbine blade is installed inside the drain pipe. One end of the turbine blade is fixedly connected to a rotating shaft. A support plate is rotatably sleeved on the outside of the rotating shaft through a sealed bearing. The bottom of the support plate is fixedly connected to the bottom of the inner cavity of the drain pipe.

[0009] The drive wheel is fixedly connected to the other end of the rotating shaft, and multiple baffles are equidistantly arranged on its outer circumference;

[0010] An elastic plate is fixed to the top of the filter screen. The end of the elastic plate away from the filter screen extends between two adjacent baffles. When the drive wheel rotates, the baffles actuate to generate elastic vibration, thereby achieving automatic cleaning of impurities on the surface of the filter screen.

[0011] Preferably, a connecting sleeve is fitted on the outer side of the turbine blade, and the outer side of the turbine blade moves against the inner wall of the connecting sleeve. A horn cover is fixedly connected to the end of the connecting sleeve away from the rotating shaft, and the outer side of the end of the horn cover away from the connecting sleeve is fixedly connected to the inner wall of the drain pipe.

[0012] Preferably, the length of the elastic plate is less than the distance between the drive wheel and the filter screen, and greater than the distance between the end of the baffle away from the drive wheel and the filter screen.

[0013] Preferably, the filter screen is arched, and the drain pipe and the filter screen together form a circular filtration structure.

[0014] Preferably, the filter screen has fixing bolts penetrating both sides of its surface, and the fixing bolts are threadedly connected to the surface of the drain pipe.

[0015] Preferably, the filter screen has mounting grooves on both sides of its surface, and the bottom of the mounting groove is flat, with the fixing bolt placed at the bottom of the mounting groove.

[0016] Preferably, the axis of the turbine blade, the axis of the rotating shaft, the axis of the drive wheel, and the axis of the drain pipe are coaxially arranged, and the turbine blade, the rotating shaft, and the drive wheel are all integrally formed from stainless steel.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. Automatic impurity removal: The turbine blades inside the drain pipe rotate under the impact of water flow, and drive the drive wheel to rotate synchronously through the rotating shaft. The outer baffle periodically actuates the elastic plate to generate vibration, and the vibration is transmitted to the filter screen surface, causing accumulated leaves, dust and other impurities to fall off with the water flow, avoiding the need for manual periodic cleaning and solving the problem of reduced drainage efficiency caused by excessive debris in existing filters.

[0019] 2. Maintaining drainage efficiency: Driven by natural water flow through the rotation of turbine blades, no additional power source is required, enabling simultaneous drainage and cleaning. Even during heavy rain, when water volume surges, the drive wheel speed increases and the vibration frequency of the elastic plate increases accordingly, enhancing the cleaning effect of the filter screen and ensuring that the drainage capacity does not decrease with the accumulation of impurities, significantly improving the long-term usability of the drainage structure.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] Example 1: A drainage structure for a substation transmission line, see [link / reference] Figures 1 to 4 ,include:

[0027] Drain pipe 1, wherein a filter screen 2 is provided at the top inlet of the drain pipe 1;

[0028] Cleaning mechanism, the cleaning mechanism comprising:

[0029] Turbine blade 3 is disposed inside the drain pipe 1. One end of the turbine blade 3 is fixedly connected to a rotating shaft 31. A support plate 32 is rotatably sleeved on the outside of the rotating shaft 31 through a sealed bearing. The bottom of the support plate 32 is fixedly connected to the bottom of the inner cavity of the drain pipe 1.

[0030] The drive wheel 33 is fixedly connected to the other end of the rotating shaft 31, and multiple baffles 34 are equidistantly arranged on its outer periphery.

[0031] An elastic plate 35 is fixed to the top of the filter screen 2. One end of the elastic plate 35 away from the filter screen 2 extends between two adjacent baffles 34. When the drive wheel 33 rotates, the baffles 34 actuate to generate elastic vibration, thereby automatically cleaning impurities on the surface of the filter screen 2. The elastic plate 35 is made of a corrosion-resistant elastic material, including but not limited to stainless steel sheets, weather-resistant rubber, or glass fiber reinforced plastic.

[0032] This device, through its cleaning mechanism, achieves the following during use:

[0033] Automatic impurity removal: The turbine blades 3 inside the drain pipe 1 rotate under the impact of water flow, and drive the drive wheel 33 to rotate synchronously through the rotating shaft 31. The outer peripheral baffle 34 periodically actuates the elastic plate 35 to generate vibration, and the vibration is transmitted to the surface of the filter screen 2, causing accumulated leaves, dust and other impurities to fall off with the water flow, avoiding manual periodic cleaning and solving the problem of reduced drainage efficiency of the existing filter screen 2 due to excessive garbage.

[0034] Maintaining drainage efficiency: The rotation of turbine blades 3 relies on natural water flow for driving, eliminating the need for an additional power source and enabling simultaneous drainage and cleaning operations. Even during heavy rain, when water volume surges, the drive wheel 33 rotates faster, and the vibration frequency of the elastic plate 35 increases synchronously, enhancing the cleaning effect of the filter screen 2 and ensuring that drainage capacity does not decrease with the accumulation of impurities, significantly improving the long-term usability of the drainage structure.

[0035] For details, see Figure 3 A connecting cylinder 4 is sleeved on the outer side of the turbine blade 3. The outer side of the turbine blade 3 moves against the inner wall of the connecting cylinder 4. A horn cover 41 is fixedly connected to the end of the connecting cylinder 4 away from the rotating shaft 31. The outer side of the end of the horn cover 41 away from the connecting cylinder 4 is fixedly connected to the inner wall of the drain pipe 1. The horn cover 41 is flared at the end away from the connecting cylinder 4, which can guide the water flow upstream of the drain pipe 1 to converge to the turbine blade 3, increase the impact area and driving torque, and ensure that the water flow can drive the turbine blade 3 to rotate. Furthermore, the inner wall of the connecting cylinder 4 moves against the outer side of the turbine blade 3 to form a flow channel to constrain the direction of water flow, reduce the lateral deviation when the blade rotates, and ensure the stable rotation of the turbine blade 3.

[0036] Further, see Figure 2 The length of the elastic plate 35 is less than the distance between the drive wheel 33 and the filter screen 2, and greater than the distance between the end of the baffle 34 away from the drive wheel 33 and the filter screen 2. This ensures that when the drive wheel 33 rotates, the baffle 34 can move the elastic plate 35. This not only prevents the elastic plate 35 from vibrating because the baffle 34 cannot pass over it when rotating due to its excessive length, but also prevents the baffle 34 from vibrating because it is too short and cannot contact the elastic plate 35 when rotating.

[0037] It is worth noting that, see Figure 1 The filter screen 2 is arched, and the drain pipe 1 and the filter screen 2 together form a circular filtration structure. The arc-shaped surface of the arched filter screen 2 can guide impurities to slide down the inclined surface, reducing the accumulation of impurities on the plane. In addition, the arched design of the filter screen 2 can disperse the vertical pressure of the water flow on the filter screen 2, reducing the deformation or damage of the filter screen 2 caused by long-term load. Combined with the rigid support of the circular drain pipe 1, it can meet the long-term use requirements of the complex outdoor environment of the substation.

[0038] It is worth noting that, see Figure 4The filter screen 2 has fixing bolts 22 penetrating both sides of its surface, and the fixing bolts 22 are threadedly connected to the surface of the drain pipe 1. The filter screen 2 has mounting grooves 21 on both sides of its surface, and the bottom of the mounting grooves 21 is flat. The fixing bolts 22 are placed at the bottom of the mounting grooves 21 and are threadedly connected to the drain pipe 1, so that the filter screen 2 can be quickly disassembled for inspection or replacement. The flat bottom of the mounting grooves 21 increases the contact area between the head of the fixing bolts 22 and the bottom of the inner cavity of the mounting grooves 21, thereby improving the firmness of the fixing bolts 22 in fixing the filter screen 2.

[0039] It is worth mentioning that, see Figure 2 The axis of the turbine blade 3, the axis of the rotating shaft 31, the axis of the drive wheel 33 and the axis of the drain pipe 1 are coaxially arranged, and the turbine blade 3, the rotating shaft 31 and the drive wheel 33 are all integrally formed of stainless steel to ensure that the water flow impact force is uniformly applied to the turbine along the axis, avoid blade wobble or bearing wear caused by eccentric load, and improve the smoothness of turbine rotation and service life.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
