Description

Technical Field

[0001] This invention relates to the field of wastewater treatment, and more particularly to an in-situ interception component for treating black and odorous river wastewater. Background Technology

[0002] In the process of treating black water, interception devices are installed in the river channel in order to carry out segmented treatment. For example, Chinese patent CN201910653095.X discloses an environmentally friendly mechanical bar screen for sewage treatment.

[0003] Bar screens need to be installed in river channels. To enhance their impact resistance, inclined auxiliary supports are typically attached to the rear of the screen. However, in practical applications, the inclined auxiliary supports take up space and are difficult to install and fix in the river channel. Furthermore, the support points for the screen are too concentrated at the connection points. To increase the number of support points, multiple support supports with multiple points of support are needed, but the number of support points is still limited, and the numerous installation points complicate the installation process. Therefore, based on practical needs, we have developed and proposed an environmentally friendly mechanical bar screen facility for wastewater treatment. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies where, in order to enhance the impact resistance of bar screens, inclined auxiliary supports are connected to the rear end of the bar screen. However, in practical applications, the inclined auxiliary supports occupy space and are difficult to install and fix in the river channel. Furthermore, the support points of the bar screen are too concentrated at the connection point. In order to increase the support points, multiple support auxiliary supports need to be set up, but the support points are still limited, and the large number of installation points makes the installation complicated. Therefore, this invention proposes an in-situ interception component for treating black and odorous river sewage.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] In one aspect, an in-situ interception assembly for treating black and odorous river wastewater is provided. The in-situ interception assembly is segmented and installed within the river channel. The assembly includes multiple mounting brackets and multiple grids inserted between adjacent mounting brackets. Each grid has a hollow structure and is connected to an aeration pump. Aeration holes are provided on the sidewalls of the grid's through-holes. The assembly also includes:

[0007] A telescopic support member, comprising a first telescopic section and a second telescopic section slidably connected to the first telescopic section, wherein the first telescopic section is located on the rear side of the grille and its end is movably mounted on a mounting bracket, and the second telescopic section contacts the back of the grille;

[0008] The positioning component includes a one-way rotating gear, a rack, and a height limiting component that limits the bottom height of the second telescopic section. The rack is installed at the bottom of the back of two adjacent mounting brackets, and the one-way rotating gear is installed at the bottom of the second telescopic section and is height-limited by the height limiting component.

[0009] In the process of flipping the telescopic support to tilt it, the one-way rotating gear moves along the rack while maintaining a constant height. When the flipping stops, the one-way rotating gear cannot roll back due to its one-way limitation, thus maintaining the tilted state of the telescopic support after it has been flipped.

[0010] To address the issue that existing technologies often use inclined auxiliary supports to enhance the impact resistance of grilles, but in practice, these supports take up space and the support points are too concentrated at the connection points. While multiple support points are needed, the number of support points remains limited, leading to complex installation. The specific implementation process to solve this problem is as follows:

[0011] During the installation of the bar screen in the river channel, the bar screen is first inserted between two mounting brackets, and multiple screens are arranged sequentially from bottom to top, with the ends connected by insertion. After the bar screen is installed, the telescopic support members movably mounted on the mounting brackets are flipped, so that there are two telescopic support members distributed in an inverted V-shape on the rear side of the bar screen. During the flipping of the telescopic support members, the height limiting component will always limit the height of the bottom end of the second telescopic section, so that the height of the bottom end of the second telescopic section remains unchanged. As a result, the first and second telescopic sections of the telescopic support members will slide, and the whole will be stretched. Thus, the telescopic support members can contact multiple bar screens in the height direction. On the one hand, this increases the support area of ​​the entire bar screen, rather than providing scattered point support, which is conducive to improving the stability of the support. On the other hand, the unidirectional movement of the gear on the rack prevents the telescopic support members from flipping in the opposite direction during the flipping adjustment process, until the ideal tilt state is adjusted, which is convenient and quick.

[0012] Specifically, there are two telescopic support members between adjacent mounting brackets, and the telescopic support members between the two mounting brackets are symmetrically arranged.

[0013] As an optional technical solution, the second telescopic section specifically includes

[0014] The first connecting frame is slidably inserted into the surface of the first telescopic section, and the bottom end of the second connecting frame is unidirectionally rotatably connected to the unidirectional rotating gear.

[0015] The top pressure frame is slidably sleeved on the surface of the first connecting frame, and guide grooves are provided on both sides. The guide grooves include a first horizontal groove, a first inclined groove and a second horizontal groove, and a first linkage pin is slidably arranged in the two second horizontal grooves.

[0016] Two clearance slots are respectively opened on both sides of the first connecting frame, and the first linkage pin passes through the clearance slot on the same side and is fixedly connected to the first telescopic section.

[0017] It should be understood that after the grille is inserted between the two mounting brackets, there is a certain distance between the back of the mounting brackets and the installed grille. Therefore, during the flipping and adjustment process, the telescopic support needs to actively conform to and support the installed grille. The specific implementation process is as follows:

[0018] During the flipping process of the telescopic support, the second telescopic section will slide on the surface of the first telescopic section, stretching the entire telescopic support. The first linkage pin on the first telescopic section will move from the first horizontal groove to the first inclined groove. During the movement in the first inclined groove, the top pressure frame will be pushed forward relative to the first connecting frame until the first linkage pin moves to the second horizontal groove and the top pressure frame is pressed against the grille.

[0019] Throughout the implementation process, before the grille was installed, the installation space between the two mounting brackets was kept unaffected by other components. After the grille was installed, the telescopic support was simply plugged in and then flipped for adjustment. During the flipping adjustment of the second telescopic section, the top pressure bracket was linked to and fitted the grille. Once fitted, the entire telescopic support was tilted, achieving a fit with the entire grille in both height and width. The inverted V-shaped distribution facilitated support for the middle part of the grille located below, moving the support points further away from the mounting brackets at both ends and bringing more support closer to the center, thus avoiding the situation where the center of the grille experiences excessive force but lacks support.

[0020] It should be further explained that when seawater overflows onto the grilles, the lower grilles experience a greater force than the upper grilles.

[0021] As a further preferred option, it also includes

[0022] The second connecting frame is disposed at the bottom end of the back of two adjacent mounting brackets, and the rack is connected to the second connecting frame.

[0023] Specifically, the height limiting component includes

[0024] A limiting rail is fixedly connected to the top of the second connecting frame, and a limiting pin is slidably disposed within the limiting rail, with the front end of the limiting pin connected to the surface of the first connecting frame.

[0025] As a further preferred option, it also includes

[0026] Two auxiliary support plates are symmetrically and rotatably connected to the top of the second connecting frame;

[0027] Two top-pressing components are respectively disposed at the rear end of the top-pressing frame at corresponding positions and in contact with the auxiliary support plate at corresponding positions.

[0028] By setting up auxiliary support plates, the rear end of the top pressure frame can be supported, thereby indirectly strengthening the support for the grid and enhancing its ability to withstand the pressure brought by the rising seawater.

[0029] Specifically, the top pressure assembly includes

[0030] A first threaded sleeve is rotatably connected to the rear end of the top pressure frame. A second threaded sleeve is threadedly connected to the inner wall of the first threaded sleeve. The second threaded sleeve is rotatably connected to the first connecting frame. A top-moving threaded rod is threadedly connected to the inner wall of the second threaded sleeve. A plug-in prism is slidably inserted into the end of the top-moving threaded rod. The plug-in prism is fixedly connected to the back of the first connecting frame.

[0031] It should be understood that during the process of the top pressure frame approaching the grid, the top pressure frame will drive the first threaded sleeve to move. The first threaded sleeve will then rotate the second threaded sleeve through the action of the thread. During the rotation of the second threaded sleeve, the thread will drive the threaded rod to slide on the plug-in prism and move closer to the auxiliary support plate until it is close to the auxiliary support plate and is supported by force.

[0032] As a further preferred embodiment, the auxiliary support plate also includes

[0033] The mounting groove is located at the top of the front side of the auxiliary support plate. A mating pressure plate is slidably installed on the inner wall of the mounting groove. A support spring is fixedly connected between the back of the mating pressure plate and the inner wall of the mounting groove.

[0034] It should be understood that as the top pressure frame rotates along with the telescopic support, it also moves synchronously and moves in an arc towards the auxiliary support plate. By setting a matching pressure plate, the gradually extending threaded rod on one side of the auxiliary support plate first contacts the matching pressure plate and then gradually presses it until the telescopic support completes its rotation, which also further strengthens the auxiliary support.

[0035] As a further preferred embodiment, a positioning component is provided at the bottom end of the back side of the auxiliary support plate, the positioning component including...

[0036] Positioning hole, the first positioning hole is formed at the bottom end of the back of the auxiliary support plate;

[0037] A plug-in slot is provided on the back of the second connecting bracket;

[0038] The positioning pin has a top pin and a bottom pin, the top pin being inserted into a positioning hole and the bottom pin being inserted into a slot.

[0039] It should be understood that by inserting the top pin of the positioning pin into the positioning hole and the bottom pin of the positioning pin into the insertion groove, the state of the auxiliary support plate being vertical to the top surface of the second connecting frame after being flipped is maintained. Furthermore, during the process of the auxiliary support plate providing auxiliary support to the top pressure frame, the positioning pin can increase the support points between the auxiliary support plate and the second connecting frame.

[0040] As a further preferred embodiment, a height adjustment component is provided between the rack and the second connecting bracket, the height adjustment component specifically including...

[0041] A movable frame is fixedly connected to the bottom of the rack and slidably inserted into the top of the second connecting frame. The movable frame has a linkage cavity, and linkage grooves are provided on both sides of the linkage cavity. The linkage grooves include a third horizontal groove and a second inclined groove.

[0042] The mounting cavity is opened through the front end of the second connecting frame. The rear end of the mounting cavity is fixedly connected to the mounting plate. The rear end of the mounting plate is rotatably connected to the adjusting screw. The adjusting screw extends into the interior of the mounting cavity. A driving block that is slidably inserted into the interior of the mounting cavity is threadedly connected to the surface of the adjusting screw. Both ends of the driving block are fixedly connected to the second linkage pins. The two second linkage pins are slidably connected in the third horizontal grooves at corresponding positions.

[0043] It should be understood that during the removal of the grille, the adjusting screw can be rotated to move the drive block via the threaded drive, thereby moving the second linkage pin from the third horizontal groove to the second inclined groove, pulling the moving frame downward, causing the rack to disengage from the one-way rotating gear, removing the limit on the one-way rotating gear, and allowing the telescopic support to be smoothly reset and retracted.

[0044] Compared with the prior art, the present invention has the following beneficial effects:

[0045] This invention achieves continuous treatment of black and odorous river wastewater by installing in-situ interception components in sections within the river channel. The hollow design of the screens oxygenates the flowing wastewater, increasing its oxygen content. Simultaneously, wastewater treatment solvents are introduced into the river channel in sections through the screens, ensuring cross-sectional contact and effective treatment of the black and odorous wastewater. The segmented interception components provide gradient treatment, achieving in-situ interception and treatment of black and odorous river wastewater. To enhance the impact resistance of the interception components, the invention utilizes a reversible telescopic support member that contacts multiple screens. This increases the support area for the entire screen, rather than providing scattered point support, thus improving stability. Furthermore, the unidirectional movement of the gear on the rack prevents the telescopic support member from reversing during adjustment, allowing for quick and convenient adjustment to the desired tilt state.

[0046] The entire telescopic support is tilted, achieving a close fit with the entire grille in both height and width. Furthermore, the inverted V-shaped distribution helps to support the middle part of the grille located below, thus moving the support points further away from the mounting brackets at both ends and bringing more support closer to the center. This prevents the grille from being subjected to excessive force in the middle without receiving support.

[0047] As the top pressure frame rotates along with the telescopic support, it moves synchronously and arcs closer to the auxiliary support plate. By setting a matching pressure plate, the gradually extending threaded rod on one side of the auxiliary support plate first contacts the matching pressure plate and then gradually presses it until the telescopic support completes its rotation, thus further strengthening the auxiliary support.

[0062] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0063] As an optional embodiment, the following is provided: Figures 1 to 13The above describes an in-situ interception assembly for treating black and odorous river wastewater. The in-situ interception assembly is installed in sections within the river. The in-situ interception assembly includes multiple mounting brackets 1 and multiple grids 2 that are plugged into adjacent mounting brackets 1.

[0064] Specifically, a pressing assembly is provided between the mounting bracket 1 and the uppermost grille 2. The pressing assembly includes a plug plate 30, which is plugged into the side of the mounting bracket 1. A push screw 31 is threadedly connected to the top surface of the plug plate 30. The push screw 31 passes through the plug plate 30 and is rotatably connected to a pressing plate 32. The bottom surface of the pressing plate 32 contacts the uppermost grille 2.

[0065] It should be understood that the grilles 2 are connected end to end by rotating the screw 31. The screw 31 moves relative to the plug plate 30 under the action of the threaded connection, thereby driving the pressing plate 32 to approach and contact the uppermost grille 2 until it is pressed tightly. The pressing component then stabilizes the connection between the grilles 2, preventing loosening during the partitioning process.

[0066] The screen 2 has a hollow structure and is connected to an aeration pump. Aeration holes 201 are provided on the side wall of the screen 2 through holes. By setting up in-situ interception components for black and odorous river sewage treatment in sections within the river channel, continuous treatment of black and odorous river sewage is achieved. The hollow design of the screen 2 oxygenates the flowing river sewage, increasing the oxygen content in the sewage. At the same time, sewage treatment solvents, such as coagulants, polyaluminum chloride, aluminum sulfate, and ferric chloride, can be added to the river channel in sections through the screen 2. This allows the added solvents to fully contact the river sewage in a cross-sectional manner, which can better treat the flowing black and odorous sewage. By setting up interception components in sections within the river channel for gradient treatment, in-situ interception and treatment of black and odorous river sewage is achieved.

[0067] To improve the impact resistance of grating 2 in the river channel, it also includes

[0068] The telescopic support includes a first telescopic section 3 and a second telescopic section 4 that is slidably connected to the first telescopic section 3. The first telescopic section 3 is located on the rear side of the grille 2 and its end is movably mounted on the mounting bracket 1. The second telescopic section 4 is in contact with the back of the grille 2.

[0069] The positioning component includes a one-way rotating gear 5, a rack 6, and a height limiting component that limits the bottom height of the second telescopic section 4. The rack 6 is installed at the bottom of the back of two adjacent mounting brackets 1, and the one-way rotating gear 5 is installed at the bottom of the second telescopic section 4 and is height-limited by the height limiting component.

[0070] During the process of flipping the telescopic support to tilt it, the one-way rotating gear 5 moves along the rack 6 while maintaining a constant height. When the flipping stops, the one-way rotating gear 5 cannot roll back due to its one-way limitation, thus maintaining the tilted state of the telescopic support after it has been flipped.

[0071] To address the issue that existing technologies often use inclined auxiliary supports to enhance the impact resistance of grilles, but in practice, these supports take up space and the support points are too concentrated at the connection points. While multiple support points are needed, the number of support points remains limited, leading to complex installation. The specific implementation process to solve this problem is as follows:

[0072] During the installation of the grating in the river channel, the grating 2 is first inserted between two mounting brackets 1, and multiple gratings are arranged sequentially from bottom to top, with the ends connected by insertion. After the grating 2 is installed, the telescopic support members movably mounted on the mounting brackets 1 are flipped, so that there are two telescopic support members distributed in an inverted V-shape on the rear side of the grating 2. During the flipping of the telescopic support members, the height limiting component will always limit the height of the bottom end of the second telescopic section 4, so that the height of the bottom end of the second telescopic section 4 remains unchanged. As a result, the first telescopic section 3 and the second telescopic section 4 of the telescopic support members will slide, and the whole will be stretched. Thus, the telescopic support members can contact multiple gratings 2 in the height direction. On the one hand, it increases the support area of ​​the entire grating, rather than the scattered point support, which is conducive to improving the stability of the support. On the other hand, through the one-way rotation of the gear 5 on the rack 6, the reverse flipping of the telescopic support members is restricted during the flipping adjustment until the ideal tilt state is adjusted, which is convenient and quick.

[0073] As an optional embodiment, there are two telescopic supports between adjacent mounting brackets 1, and the telescopic supports between the two mounting brackets 1 are symmetrically arranged.

[0074] As an optional embodiment, the second telescopic segment 4 specifically includes

[0075] The first connecting frame 401 is slidably inserted into the surface of the first telescopic section 3, and the bottom end of the second connecting frame 7 is unidirectionally rotatably connected to the one-way rotating gear 5.

[0076] Specifically, the one-way rotating gear 5 can be connected to the bottom end of the second connecting frame 7 through a one-way bearing to achieve one-way rotation restriction.

[0077] The top pressure frame 402 is slidably sleeved on the surface of the first connecting frame 401, and guide grooves are provided on both sides. The guide grooves include a first horizontal groove 403, a first inclined groove 404 and a second horizontal groove 405. A first linkage pin 406 is slidably arranged in the two second horizontal grooves 405.

[0078] Two clearance slots 407 are respectively opened on both sides of the first connecting frame 401. The first linkage pin 406 passes through the clearance slot 407 on the same side and is fixedly connected to the first telescopic section 3.

[0079] It should be understood that after the grille 2 is inserted between the two mounting brackets 1, there is a certain distance between the back of the mounting bracket 1 and the installed grille 2. Therefore, during the flipping and adjustment process, the telescopic support needs to actively conform to and support the installed grille 2. The specific implementation process is as follows:

[0080] During the flipping process of the telescopic support, the second telescopic section 4 slides on the surface of the first telescopic section 3, elongating the entire telescopic support. The first linkage pin 406 on the first telescopic section 3 moves from the first horizontal groove 403 to the first inclined groove 404. During its movement within the first inclined groove 404, it pushes the top pressure frame 402 forward relative to the first connecting frame 401 until the first linkage pin 406 moves to the second horizontal groove 405. Then, the top pressure frame 402 adheres tightly to the grille 2, achieving the desired effect. Figure 2 The state;

[0081] Throughout the implementation process, before the grille 2 is installed, the installation space between the two mounting brackets 1 is kept unaffected by other components. After the grille 2 is installed, the telescopic support is simply plugged in and then flipped for adjustment. During the flipping and adjustment of the second telescopic section 4, the top pressure bracket 402 is linked to fit the grille 2. After the fit is completed, the entire telescopic support is tilted, achieving fit with the entire grille in both height and width. Furthermore, the inverted V-shaped distribution helps to support the middle position of the grille 2 located below, moving the support points further away from the mounting brackets 1 at both ends and bringing more support closer to the middle, thus avoiding the situation where the middle of the grille 2 is subjected to excessive force but does not receive support.

[0082] It should be further explained that when seawater overflows the grille, the lower grille 2 experiences a higher force than the upper grille.

[0083] As a further embodiment, it also includes

[0084] The second connecting frame 7 is located at the bottom of the back of two adjacent mounting brackets 1, and the rack 6 is connected to the second connecting frame 7.

[0085] Specifically, a connecting groove is made at the bottom of the back of the mounting bracket 1, the second connecting bracket 7 is slidably inserted into the connecting groove, and then the mounting bracket 1 and the second connecting bracket 7 are positioned by fastening bolts through the mounting bracket 1 and the second connecting bracket 7.

[0086] As an optional embodiment, the height limiting component specifically includes

[0087] The limiting rail 8 is fixedly connected to the top of the second connecting frame 7. A limiting pin 9 is slidably provided inside the limiting rail 8, and the front end of the limiting pin 9 is connected to the surface of the first connecting frame 401.

[0088] As an optional embodiment, the front end of the limiting pin 9 is fixedly connected or rotatably connected to the surface of the first connecting frame 401.

[0089] It should be understood that when the limiting pin 9 is always sliding on the limiting track 8, the height of the limiting pin 9 will always be limited, and it can only slide laterally. The height of the bottom end of the first connecting frame 401 on the second telescopic section 4 connected to the limiting pin 9 is also limited, so that the bottom end of the first connecting frame 401 is always located at the bottom of the back of the entire grille.

[0090] As a further embodiment, it also includes

[0091] Two auxiliary support plates 10 are symmetrically and rotatably connected to the top of the second connecting frame 7;

[0092] Two top-pressure components are respectively set at the rear end of the top-pressure frame 402 at the corresponding position and in contact with the auxiliary support plate 10 at the corresponding position.

[0093] By setting the auxiliary support plate 10, the rear end of the top pressure frame 402 can be supported, thereby indirectly strengthening the support of the grid 2, which is conducive to strengthening the grid 2's ability to withstand the pressure brought by the overflowing seawater.

[0094] As an optional embodiment, the top pressure assembly specifically includes

[0095] A first threaded sleeve 11 is rotatably connected to the rear end of the top pressure frame 402. A second threaded sleeve 12 is threadedly connected to the inner wall of the first threaded sleeve 11. The second threaded sleeve 12 is rotatably connected to the first connecting frame 401. A top threaded rod 13 is threadedly connected to the inner wall of the second threaded sleeve 12. A plug-in prism 14 is slidably inserted into the end of the top threaded rod 13. The plug-in prism 14 is fixedly connected to the back of the first connecting frame 401.

[0096] It should be understood that during the process of the top pressure frame 402 approaching the grid 2, the top pressure frame 402 will drive the first threaded sleeve 11 to move. The first threaded sleeve 11 will rotate the second threaded sleeve 12 through the action of the thread. During the rotation of the second threaded sleeve 12, it will drive the top threaded rod 13 to slide on the plug-in prism 14 through the thread, and move closer to the auxiliary support plate 10 until it is close to the auxiliary support plate 10 and is supported by force.

[0097] As a further embodiment, the auxiliary support plate 10 also includes

[0098] Mounting groove 15 is located at the top of the front of the auxiliary support plate 10. A mating pressure plate 16 is slidably mounted on the inner wall of the mounting groove 15. A support spring 17 is fixedly connected between the back of the mating pressure plate 16 and the inner wall of the mounting groove 15.

[0099] It should be understood that as the top pressure frame 402 rotates with the telescopic support, it also moves synchronously and moves in an arc shape to approach the auxiliary support plate 10. By setting the mating pressure plate 16, the gradually extending push threaded rod 13 on one side of the auxiliary support plate 10 first contacts the mating pressure plate 16 and then gradually presses it until the telescopic support is rotated, which also achieves further strengthening of the auxiliary support.

[0100] As a further embodiment, a positioning component is provided at the bottom end of the back side of the auxiliary support plate 10, the positioning component including...

[0101] Positioning hole 18, the first positioning hole 18 is opened at the bottom end of the back of the auxiliary support plate 10;

[0102] Insertion slot 19, the insertion slot 19 is opened on the back of the second connecting bracket 7;

[0103] The positioning pin 20 has a top pin and a bottom pin. The top pin is inserted into the positioning hole 18, and the bottom pin is inserted into the insertion groove 19.

[0104] It should be understood that by inserting the top pin of the positioning pin 20 into the positioning hole 18 and the bottom pin of the positioning pin 20 into the insertion groove 19, the state in which the auxiliary support plate 10 is flipped and perpendicular to the top surface of the second connecting frame 7 is maintained. In the process of the auxiliary support plate 10 providing auxiliary support to the top pressure frame 402, the positioning pin 20 can increase the support points between the auxiliary support plate 10 and the second connecting frame 7.

[0105] As a further embodiment, a height adjustment assembly is provided between the rack 6 and the second connecting bracket 7, the height adjustment assembly specifically including...

[0106] The movable frame 21 is fixedly connected to the bottom of the rack 6 and slidably inserted into the top of the second connecting frame 7. The movable frame 21 has a linkage cavity 22, and linkage grooves are provided on both sides of the linkage cavity 22. The linkage grooves include a third horizontal groove 23 and a second inclined groove 24.

[0107] The mounting cavity 25 is opened through the front end of the second connecting frame 7. The rear end of the mounting cavity 25 is fixedly connected to the mounting plate 26. The rear end of the mounting plate 26 is rotatably connected to the adjusting screw 27. The adjusting screw 27 extends into the interior of the mounting cavity 25. The surface of the adjusting screw 27 is threaded with a drive block 28 that is slidably inserted into the interior of the mounting cavity 25. Both ends of the drive block 28 are fixedly connected to the second linkage pins 29. The two second linkage pins 29 are slidably connected in the third horizontal groove 23 at the corresponding positions.

[0108] It should be understood that during the removal of the grille, the adjusting screw 27 can be rotated to move the drive block 28 via the threaded drive, thereby moving the second linkage pin 29 from the third horizontal groove 23 to the second inclined groove 24, thereby pulling the moving frame 21 downward, causing the rack 6 to disengage from the one-way rotating gear 5, canceling the limit on the one-way rotating gear 5, and allowing the telescopic support to be smoothly reset and retracted.

[0109] Before installing the in-situ interception components, concrete foundation piles need to be set on both sides of the river channel. Adjustable span suspensions are fixed on the foundation piles. Then, the assembled in-situ interception components are inserted into the river channel in an inverted manner, and the base of the mounting bracket 1 is fixed on the suspension.

[0110] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
