Description

Technical Field

[0001] This invention belongs to the field of drainage technology, specifically a diversion device with a flexible interceptor. Background Technology

[0002] A diversion device is a flow-blocking facility used at the outlet or discharge point of a diversion well. Its structure typically includes an outer shell and a rubber sleeve, with a pressurized cavity formed between the outer shell and the rubber sleeve. By filling the pressurized cavity with pressurized gas, the rubber sleeve deforms under inward pressure, and its inner wall gradually closes, thereby completely cutting off the flow channel.

[0003] In existing technologies, the water flow at the outlet or discharge point of a diversion well typically carries impurities such as silt, sand, and fibrous debris. When the rubber sleeve is in an open state without flow interception, these impurities easily adhere to or deposit on the inner wall surface of the rubber sleeve. When the impurities accumulate to a certain amount, and pressurized gas is injected into the pressurization chamber, driving the rubber sleeve to deform inward and attempt to make the inner walls fit together to achieve flow interception, the impurity particles attached to the inner wall surface of the rubber sleeve will be trapped between the two mating surfaces, forming local gaps or microchannels. This prevents the inner walls of the rubber sleeve from completely sealing tightly, reducing the sealing performance, and allowing water to still leak through these gaps, thus affecting the flow interception effect and making it difficult to achieve complete flow interruption. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, the present invention proposes a diversion device with a flexible interceptor.

[0012] The segmented radial scraping assembly includes multiple radial rods evenly distributed circumferentially and slidably connected to one side surface of the chassis. One end of each radial rod is fixedly connected to a support column, and one side of the support column is slidably connected to a slide rod 1 and a slide rod 2. One end of slide rod 1 is fixedly connected to a push plate 1, and one end of slide rod 2 is fixedly connected to a push plate 2. Adjacent push plates 1 and 2 are slidably inserted into each other.

[0013] Preferably, a spring is sleeved on one end of the slide rod, one end of which is fixedly connected to the push plate and the other end is fixedly connected to the support column. A spring is sleeved on one side of the slide rod, one end of which is fixedly connected to the push plate and the other end is fixedly connected to the support column.

[0014] Preferably, a support column is fixedly connected to one end face of the chassis, a fixed plate is fixedly connected to one end of the support column, a lead screw is rotatably connected to one side of the fixed plate, the other end of the lead screw is rotatably connected to the middle of the chassis, the lead screw is threadedly connected to a threaded sleeve, and multiple connecting rods are evenly distributed and rotatably connected to the threaded sleeve along the circumference, and the end of each connecting rod away from the threaded sleeve is rotatably connected to the end of a radial rod.

[0015] Preferably, a motor is fixedly connected to one side of the fixed plate, and the output end of the motor is fixedly connected to one end of the lead screw.

[0016] Preferably, the chassis is equipped with an anti-caking and anti-edge-crossing component;

[0017] The anti-caking and edge-crossing component includes a support plate fixedly connected to one side of the chassis. A transverse column is slidably connected to one side surface of the support plate. A rotating shaft is rotatably connected to one end of the transverse column, and a blade is fixedly connected to one end of the rotating shaft.

[0018] Preferably, one end of the transverse column is threadedly connected to a lead screw two, both ends of the lead screw two are rotatably connected to a support plate, one end of the support plate is fixedly connected to a motor three, the output end of the motor three is fixedly connected to one end of the lead screw two, one end of the transverse column is fixedly connected to a motor four, the output end of the motor four is fixedly connected to one end of the rotating shaft, one end of the bracket is fixedly connected to a motor two, and the output end of the motor two is fixedly connected to one end of the rotating plate.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The diversion device with a flexible interceptor described in this invention utilizes an elastically adjustable scraping assembly to periodically remove impurities adhering to the inner wall of the rubber sleeve, effectively maintaining the cleanliness of the inner wall. This fundamentally avoids the problem of impurities adhering to or depositing on the surface of the inner wall of the rubber sleeve with the water flow, causing impurity particles to be trapped between the two contact surfaces when the rubber sleeve deforms and closes inward, forming local gaps or microchannels, thus resulting in poor sealing and inability to achieve complete flow interruption. Furthermore, during scraping of the inner wall of the rubber sleeve, the scraping pad and the base work together to achieve comprehensive circumferential coverage of the inner wall of the rubber sleeve, thoroughly removing impurities in a single scraping operation, resulting in high cleaning efficiency.

[0021] 2. The diversion device with a flexible flow-blocking component described in this invention utilizes a segmented radial scraping assembly. After the scraper pad is removed from the rubber sleeve, multiple push plates 1 and 2 move along the surface of the scraper pad and scrape off the impurities attached to its surface until the impurities fall off through the edge of the scraper pad. This achieves self-cleaning of the scraper pad surface, avoiding the problem of reduced edge flexibility and fit of the scraper pad due to long-term accumulation and hardening of impurities on the scraper pad surface. This ensures that the scraper pad can effectively scrape off the impurities attached to the inner wall of the rubber sleeve in each subsequent scraping operation, while preventing the squeezing and friction damage caused by impurity particles on the surface of the scraper pad to the inner wall of the rubber sleeve. This ensures the smoothness and sealing of the inner wall of the rubber sleeve, thereby maintaining a long-term stable flow-blocking effect.

[0022] Furthermore, push plates one and two correspond to the scraping pad portion between the two stretching blocks, and push plates one and two are tightly fitted to the scraping pad surface under the action of springs one and two. Compared to scraping with a single scraping tool, this segmented independent scraping combined with elastic adaptive fitting avoids the defect of a single flat scraping tool being unable to effectively fit the area due to local depressions on the scraping pad surface, thus preventing impurities from remaining. Under the action of springs one and two, each set of push plates one and two can automatically adjust the fitting state according to the undulations of the scraping pad surface, ensuring comprehensive scraping of all areas of the scraping pad surface, resulting in more thorough cleaning without dead corners. Moreover, during the scraping process, the size of the barrier formed by multiple push plates one and two continuously expands, thereby intercepting impurities from all directions and preventing impurities from moving to areas already scraped by the scraping pad, further ensuring the self-cleaning effect.

[0023] 3. The diversion device with a flexible intercepting component described in this invention utilizes an anti-caking and edge-crossing assembly. When the scraper pad scrapes impurities from the inner wall of the rubber sleeve, the blade performs a combined rotation and revolution motion. The blade cuts the hard clumps on the inner wall of the rubber sleeve into small, easily scraped fragments, thus eliminating the risk of the scraper pad edge bending and deforming due to excessively hard clumps, allowing it to cross over impurities. The chopped impurity fragments can be smoothly scraped away by the scraper pad as the chassis moves out, further ensuring the cleaning effect on the impurities on the inner wall of the rubber sleeve.

[0036] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1:

[0038] Please refer to Figures 1-10 The present invention provides a technical solution: a diversion device with a flexible interceptor, including an outer shell 1 and a rubber sleeve 3. The rubber sleeve 3 is disposed on the inner wall of the outer shell 1, and an air cavity is formed between the inner wall of the outer shell 1 and the outer wall of the rubber sleeve 3. An air nozzle 35 communicating with the air cavity is provided on one side of the outer shell 1, and includes an elastic adjustable scraping component for removing impurities from the inner surface of the rubber sleeve 3.

[0039] The elastically adjustable scraping assembly includes a chassis 20, which is axially aligned with the outer shell 1. A circular scraping pad 9 is fixedly fitted at the edge of the chassis 20. The scraping pad 9 is annular. Multiple rotating rods 31 are evenly distributed and rotatably connected to one side surface of the chassis 20. A tension block 30 is fixedly connected to one end of each rotating rod 31. The tension block 30 is fixedly connected to the scraping pad 9 by bolts. Before gas is injected into the inflation chamber, the chassis 20 extends into the inner cavity of the outer shell 1 and moves to its end. Multiple tension blocks 30 rotate simultaneously, causing the scraping pad 9 to deform and its edge to adhere to the inner wall of the rubber sleeve 3. The chassis 20 moves out along the original path, and the scraping pad 9 scrapes off the impurities adhering to the inner wall of the rubber sleeve 3.

[0040] like Figure 1 As shown, the outer casing 1 is provided with a lateral displacement mechanism for driving the chassis 20 to move;

[0041] The lateral displacement mechanism includes a bracket 2 that is slidably connected to one side of the outer wall of the outer shell 1. One end of the bracket 2 is rotatably connected to a rotating plate 7. Multiple connecting rods 8 are fixedly connected to one side end face of the rotating plate 7. The end of the connecting rod 8 away from the rotating plate 7 is fixedly connected to one side surface of the chassis 20.

[0042] like Figure 1 As shown, one end of the bracket 2 is threadedly connected to a lead screw 4, both ends of which are rotatably connected to the outer casing 1. A motor 5 is fixedly connected to one side of the outer wall of the outer casing 1, and the output end of the motor 5 is fixedly connected to one end of the lead screw 4.

[0043] like Figure 8 and Figure 9 As shown, the chassis 20 is provided with a synchronous transmission assembly for driving multiple rotating rods 31 to rotate simultaneously; the synchronous transmission assembly includes an electric push rod 32 fixedly connected to the middle of one side end face of the chassis 20, a connecting block 33 fixedly connected to the piston end of the electric push rod 32, and multiple connecting rods 34 evenly distributed and rotatably connected along the circumference of the connecting block 33, and the end of each connecting rod 34 away from the connecting block 33 is rotatably connected to the end of a rotating rod 31.

[0044] Specifically, in existing technologies, the water flow at the outlet or discharge point of the diversion well typically carries impurities such as silt, sand, and fibrous debris. When the rubber sleeve 3 is in an open state without interception, these impurities easily adhere to or deposit on the inner wall surface of the rubber sleeve 3 with the water flow. When the impurities accumulate to a certain amount, and pressurized gas is injected into the pressurization chamber to drive the rubber sleeve 3 to deform inward and attempt to make the inner walls fit together to achieve interception, the impurity particles attached to the inner wall surface of the rubber sleeve 3 will be trapped between the two mating surfaces, forming local gaps or microchannels. This prevents the inner walls of the rubber sleeve 3 from completely and tightly fitting together, reducing the sealing performance. Water can still leak through these gaps, thus affecting the interception effect and making it difficult to achieve complete flow interruption.

[0045] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0046] The outer casing 1 is installed at the outlet or drain of the diversion well. The specific method of connecting the air nozzle 35 to the inflation device to inject pressurized gas into the inflation chamber is a conventional technique in this field. For example, pressurized gas can be introduced into the inflation chamber through an inflation device consisting of an external air source such as an air compressor or air tank, an air pipeline, and a control valve assembly; its specific structure and working principle will not be elaborated here.

[0047] When there is no water flow or no need to cut off the flow, the inflation device does not fill the inflation chamber with pressurized gas, and the rubber sleeve 3 is in a naturally open state, forming a through flow channel between its inner walls, allowing water to flow normally.

[0048] When it is necessary to cut off the water flow, the inflation device fills the inflation chamber with pressurized gas. Under the action of gas pressure, the rubber sleeve 3 undergoes elastic deformation inward, and its inner wall gradually closes until the flow channel is completely sealed, thus achieving the interception.

[0049] Furthermore, in its initial state, the chassis 20 is located outside the rubber sleeve 3, not affecting the flow of water, and the outer edge of the scraper pad 9 is folded. Typically, on sunny days or at the beginning of rainfall, to prevent sewage or polluted initial rainwater from directly flowing into rivers, the channels to natural water bodies are completely closed. At this time, the interior of the outer casing 1 is in a state of no water flow or very little water flow, making it an ideal time for cleaning. The elastically adjustable scraping assembly can operate during this period. Motor 5 drives the lead screw 4 to rotate, causing the bracket 2 to move laterally along the outer wall of the outer casing 1, allowing the chassis 20 to extend into the inner cavity of the rubber sleeve 3 until it reaches the end of the inner cavity. Furthermore, since the outer edge of the scraper pad 9 is folded at this time, the outer edge of the scraper pad 9 will not touch the inner wall of the rubber sleeve 3.

[0050] Subsequently, the electric actuator 32 drives the connecting block 33 to move away from the chassis 20. The connecting block 33 drives multiple connecting rods 34 and rotating rod 31 to rotate synchronously. Multiple tensioning blocks 30 simultaneously drive the scraper pad 9 to deform and unfold. The unfolded scraper pad 9 is a regular circular ring, and the edge of the scraper pad 9 is in contact with the inner wall of the rubber sleeve 3. At this time, the chassis 20 is driven to move out of the rubber sleeve 3 along the original path. During the process, the scraper pad 9 will use its edge to scrape the impurities attached to the inner wall surface of the rubber sleeve 3 until the impurities are pushed out of the rubber sleeve 3. Thus, the removal of impurities attached to the inner wall of the rubber sleeve 3 is achieved. The above operation is repeated periodically to ensure the cleanliness of the inner wall of the rubber sleeve 3. This prevents impurities from adhering to or depositing on the surface of the inner wall of the rubber sleeve 3 with the water flow. This prevents impurity particles from being trapped between the two mating surfaces when the rubber sleeve 3 deforms inward, forming local gaps or microchannels. Consequently, the inner wall of the rubber sleeve 3 cannot be completely tightly fitted, affecting the flow interception effect and making it difficult to achieve complete flow interruption. Furthermore, when the scraper pad 9 scrapes the inner wall of the rubber sleeve 3, it works in conjunction with the base plate 20 to fully cover the cross-sectional area of ​​the rubber sleeve 3. A single scraping can thoroughly remove impurities, resulting in high cleaning efficiency.

[0051] Example 2:

[0052] like Figure 4 and Figure 5As shown, the chassis 20 is provided with a segmented radial scraping assembly for removing impurities adhering to the surface of the scraper pad 9;

[0053] The segmented radial scraping assembly includes multiple radial rods 12 that are evenly distributed circumferentially and slidably connected to one side surface of the chassis 20. One end of each radial rod 12 is fixedly connected to a support column 21. One side of the support column 21 is slidably connected to a slide rod 22 and a slide rod 36. One end of the slide rod 22 is fixedly connected to a push plate 10, and one end of the slide rod 36 is fixedly connected to a push plate 11. Adjacent push plates 10 and 21 are slidably inserted into each other.

[0054] like Figure 5 As shown, a spring 23 is fitted on one end of the slide rod 22. One end of the spring 23 is fixedly connected to the push plate 10, and the other end is fixedly connected to the support column 21. A spring 37 is fitted on one side of the slide rod 36. One end of the spring 37 is fixedly connected to the push plate 11, and the other end is fixedly connected to the support column 21.

[0055] like Figure 6 and Figure 7 As shown, a support column 25 is fixedly connected to one end face of the chassis 20. A fixing plate 29 is fixedly connected to one end of the support column 25. A lead screw 28 is rotatably connected to one side of the fixing plate 29. The other end of the lead screw 28 is rotatably connected to the middle of the chassis 20. A threaded sleeve 24 is threadedly connected to the lead screw 28. Multiple connecting rods 27 are evenly distributed and rotatably connected along the circumference of the threaded sleeve 24. The end of each connecting rod 27 away from the threaded sleeve 24 is rotatably connected to the end of a radial rod 12.

[0056] like Figure 6 and Figure 7 As shown, a motor 26 is fixedly connected to one side of the fixed plate 29, and the output end of the motor 26 is fixedly connected to one end of the lead screw 28.

[0057] Specifically, in the above embodiments, although the scraper pad 9 can be used to remove impurities adhering to the inner wall of the rubber sleeve 3, since the scraper pad 9 is made of elastic material, impurities also easily adhere to its surface. Over time, impurities will gradually accumulate and harden on the surface of the scraper pad 9, resulting in a decrease in the flexibility and fit of the scraper pad 9 edges. When the scraper pad 9 unfolds again and scrapes along the inner wall of the rubber sleeve 3 with the chassis 20, the edges of the scraper pad 9, which are already covered with impurities, not only fail to completely clean the inner wall of the rubber sleeve 3, but may also scratch or wear the inner wall surface of the rubber sleeve 3 due to the squeezing and friction of the surface impurity particles, damaging its smoothness and sealing performance. Once the inner wall of the rubber sleeve 3 is damaged, impurities are more likely to hide in the damaged area during subsequent pressurization and closure, forming leakage channels that are more difficult to eliminate, ultimately leading to closure failure.

[0058] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0059] In the initial state, multiple push plates 10 and 11 are located at the edge of the chassis 20. These push plates cooperate to form a perimeter around the edge of the chassis 20. After the scraper pad 9 is deployed, the push plates 10 and 11, under the action of springs 23 and 37, adhere tightly to the surface of the scraper pad 9. Furthermore, impurities located on the upper side of the inner wall of the rubber sleeve 3 are scraped off and fall onto the perimeter surface.

[0060] After the scraper pad 9 is removed from the rubber sleeve 3, the motor 26 drives the lead screw 28 to rotate, which moves the threaded sleeve 24. The threaded sleeve 24 drives multiple connecting rods 27 to rotate, and multiple radial rods 12 move simultaneously away from the axis of the chassis 20. Multiple push plates 10 and 11 move along the surface of the scraper pad 9 and scrape off the impurities attached to its surface until the impurities fall off the edge of the scraper pad 9. This achieves self-cleaning of the scraper pad 9 surface and avoids the problem of reduced edge flexibility and fit of the scraper pad 9 due to long-term accumulation and hardening of impurities on the scraper pad 9 surface. This ensures that the scraper pad 9 can effectively scrape off the impurities attached to the inner wall of the rubber sleeve 3 in each subsequent scraping operation, while preventing the squeezing and friction damage caused by the impurity particles on the surface of the scraper pad 9 to the inner wall of the rubber sleeve 3. This ensures the smoothness and sealing of the inner wall of the rubber sleeve 3, and thus maintains a long-term stable interception effect.

[0061] Furthermore, a set of push plates 10 and 11 correspond to the scraping pad 9 between the two stretching blocks 30, and push plates 10 and 11 are tightly attached to the surface of the scraping pad 9 under the action of springs 23 and 37. Compared with the method of scraping using a single scraping tool, this segmented independent scraping combined with elastic adaptive attachment avoids the defect of a single flat scraping tool being unable to effectively adhere to the area due to local concavity on the surface of the scraping pad 9, thus preventing the residue of impurities. Under the action of springs 23 and 37, each set of push plates 10 and 11 can automatically adjust the attachment state according to the undulation of the scraping pad 9 surface, ensuring that all areas of the scraping pad 9 surface are thoroughly scraped, resulting in a more thorough cleaning without dead corners. Moreover, during the scraping process, the size of the barrier formed by multiple push plates 10 and 11 continuously expands, thereby intercepting impurities from all directions and preventing impurities from moving to the areas already scraped by the scraping pad 9, further ensuring the self-cleaning effect.

[0062] Example 3:

[0063] like Figure 2 and Figure 3 As shown, the chassis 20 is equipped with an anti-caking and edge-crossing component;

[0064] The anti-caking and edge-crossing component includes a support plate 13 fixedly connected to one side of the chassis 20, a transverse column 14 slidably connected to one side surface of the support plate 13, a rotating shaft 19 rotatably connected to one end of the transverse column 14, and a blade 15 fixedly connected to one end of the rotating shaft 19.

[0065] like Figure 3 As shown, one end of the transverse column 14 is threadedly connected to a lead screw 16, both ends of which are rotatably connected to the support plate 13. One end of the support plate 13 is fixedly connected to a motor 17, the output end of which is fixedly connected to one end of the lead screw 16. One end of the transverse column 14 is fixedly connected to a motor 18, the output end of which is fixedly connected to one end of the rotating shaft 19. One end of the bracket 2 is fixedly connected to a motor 6, the output end of which is fixedly connected to one end of the rotating plate 7.

[0066] Specifically, in the above embodiments, although the scraper pad 9 can be used to scrape off the impurities attached to the inner wall of the rubber sleeve 3, when the impurities are hard lumps, the edge of the scraper pad 9 may bend and deform due to the obstruction of the impurities, and thus pass over the impurities, resulting in the impurities not being effectively removed and affecting the cleaning effect.

[0067] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0068] Initially, the blade 15 is positioned at the edge of the scraper pad 9. When the scraper pad 9 scrapes impurities from the inner wall of the rubber sleeve 3, the motor 18 drives the rotating shaft 19 and the blade 15 to rotate. Simultaneously, the motor 6 drives the rotating plate 7 to rotate, causing the chassis 20 and the scraper pad 9 to rotate synchronously. This causes the blade 15 to perform a combined rotation and revolution motion. Since the blade 15 is located at the edge of the scraper pad 9 and does not contact the inner wall of the rubber sleeve 3, it will break down hard clumps into small, easily scraped debris. This eliminates the risk of the scraper pad 9 bending or deforming due to excessively hard clumps, allowing it to pass over impurities. The chopped debris can be easily scraped away by the scraper pad 9 as the chassis 20 moves out, further ensuring the cleaning effect on the inner wall of the rubber sleeve 3.

[0069] Furthermore, when the scraper pad 9 is removed from the rubber sleeve 3, the motor 3 17 drives the lead screw 2 16 to rotate, causing the transverse column 14 to move, and the blade 15 to move away from the scraper pad 9, without affecting the movement of the push plate 1 10 and the push plate 2 11.
