Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to an underwater bubble curtain sediment interception device. Background Technology

[0002] Today, river dredging is one of the important means of water conservancy construction. Its main functions are to increase the smooth flow of waterways, prevent floods and drain waterlogging, improve the aquatic ecological environment, and promote ecological self-repair. However, its disadvantages are that it has a long cycle, a large amount of engineering work, and a continuous impact on the surrounding water quality and environment. In traditional construction operations, dredging equipment causes severe disturbance to the bottom sediment, a large amount of silt is suspended, the turbidity of the surrounding water increases, and the muddy water spreads outward under the action of water flow and wind.

[0003] A search revealed Chinese patent publication number CN211340706U, which discloses an adjustable-aperture sediment interception device. The device includes an interception plate with several through-slots arranged in a matrix on its sidewalls. A filter screen is installed within each through-slot. Vertically symmetrical settling grooves are formed on both sides of the through-slots on the sidewalls of the interception plate. Sliding grooves are symmetrically formed on both sides of each settling groove. A support with an inverted "U" shape is mounted on the top surface of the interception plate. A connecting plate is located on one side of the top surface of the support. This adjustable-aperture sediment interception device uses a cylinder to move a crossbar up and down, allowing a disc to move up and down. The device allows for control of the trough's aperture, thus controlling the water discharge rate. As the disc moves up and down, its brushes contact the filter screen, preventing clogging. This solves the problems of not being able to control the water discharge rate and the time-consuming and laborious process of unclogging the filter screen. However, in actual use, while the device can prevent the spread of silt and sand in the water to a certain extent, its height can obstruct ship navigation, limiting its applicability. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an underwater bubble curtain sediment interception device, which aims to improve the problem that the device itself has a certain height, which will hinder the navigation of ships and limit its scope of use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an underwater bubble curtain sediment interception device, comprising a fixed plate, an air compressor fixedly connected to the top wall of the fixed plate, a flow meter fixedly installed on the bottom left side of the air compressor, a conveying pipe connected to the bottom end of the flow meter, a valve fixedly connected to the rear end of the conveying pipe, a connecting pipe connected to the rear end of the valve, a connecting shell connected to the rear end of the connecting pipe, a plurality of nozzles equidistantly connected to the top wall of the connecting shell, a base fixedly connected to the bottom of the connecting shell, limit components provided on the top left and right sides of the base, mounting components provided on the front and rear sides of the fixed plate, and a connecting mechanism provided on the left side of the base.

[0006] The above technical solution enables high-pressure airflow to be output through multiple nozzles to continuously release bubbles, thereby changing the surrounding flow field. This causes the surrounding water to move upwards with a large number of bubbles, and after reaching the water surface, the bubbles flow to both sides to form a surface horizontal flow. Continuous aeration will form a vertical circulation on both sides of the bubble curtain, and the sediment will be restricted to the turbid water side under the action of the circulation, thus avoiding obstruction of ship navigation. It has a wide range of applications.

[0007] As a further description of the above technical solution:

[0008] The connecting mechanism includes two mounting plates. The right sides of the two mounting plates are fixedly connected to the front and rear ends of the left side of the base, respectively. The front and rear ends of the right side of the base are provided with mounting slots. The left side of the mounting plate engages with the mounting slot. The front and rear ends of the right side of the top wall of the base are rotatably connected with locking plates. The front and rear ends of the left side of the top wall of the base are provided with locking slots. The bottom of the locking plate engages with the locking slot. The left side of the connecting shell is connected to a connecting valve. The rear side of the base is provided with a snap-fit ​​assembly.

[0009] The above technical solution enables the initial connection and engagement of the base through the connection between the mounting plate and the mounting groove. Then, the locking plate is flipped to fix the locking position, thereby improving the stability of the base connection. Subsequently, multiple connecting shells can be connected through the connecting valve, thereby increasing the number of bubble curtains and improving the effect of mud and sand interception.

[0010] As a further description of the above technical solution:

[0011] The limiting component includes two threaded rods, the bottom ends of which are rotatably connected to the left and right sides of the top wall of the base, respectively. A turntable is fixedly connected to the top of the threaded rods, and a lifting plate is threadedly connected to the outer wall of the threaded rods. Limiting cones are fixedly connected to the front and rear sides of the bottom wall of the lifting plate, and the middle parts of the plurality of limiting cones are slidably connected to the interior of the base.

[0012] The above technical solution enables the threaded rod to rotate synchronously with the turntable. Then, under the restriction of the lifting plate of the limiting cone, the lifting plate drives the limiting cone to rise and fall, thereby allowing the limiting cone to penetrate deep into the ground and achieve the effect of limiting and fixing the base.

[0013] As a further description of the above technical solution:

[0014] The snap-fit ​​assembly includes multiple snap-fit ​​posts, and multiple snap-fit ​​slots are equally spaced on the rear side of the base. The rear ends of the snap-fit ​​posts engage with the snap-fit ​​slots.

[0015] The above technical solution enables the longitudinal connection of the base by connecting the snap-fit ​​post and the snap-fit ​​slot, thereby increasing the length of the bubble curtain.

[0016] As a further description of the above technical solution:

[0017] The mounting assembly includes multiple mounting bases, with adjacent sides of each mounting base fixedly connected to the outer wall of the fixing plate, and mounting holes provided on the top wall of each mounting base.

[0018] The above technical solution allows for easy selection of the mounting position of the fixing plate by setting the mounting base and mounting holes.

[0019] As a further description of the above technical solution:

[0020] A control switch is fixedly connected to the right side of the top wall of the fixed plate. The control switch is electrically connected to the air compressor, flow meter and valve respectively.

[0021] The above technical solution enables the device to be turned on and off by connecting the control switch.

[0022] As a further description of the above technical solution:

[0023] The connecting mechanism also includes a sealing ring, the inner wall of which is fixedly connected to the outer wall of the connecting valve, the outer wall of which is fixedly connected to the left side of the connecting shell, and rubber rings are fixedly connected to the outer walls of both mounting plates.

[0024] The above technical solution improves the sealing effect at the connection between the connecting valve and the connecting shell by using a sealing ring, and enhances the fixing effect of the mounting plate by using a rubber ring.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the airflow output of the air compressor is used to output high-pressure airflow through multiple nozzles to produce bubbles. The continuously released bubbles can change the surrounding flow field. The surrounding water moves upward with a large number of bubbles. After reaching the water surface, it flows to both sides to form a surface horizontal flow. Continuous aeration will form a vertical circulation on both sides of the bubble curtain. The sediment will be restricted to the turbid water side under the action of the circulation, thereby avoiding obstruction of ship navigation. It has a wide range of applications.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of an underwater bubble curtain sediment interception device, comprising a fixed plate 1, with an air compressor 3 fixedly connected to the top wall of the fixed plate 1, enabling airflow delivery via a flow meter 4 and a delivery pipe 5 under the operation of the air compressor 3. A flow meter 4 is fixedly installed on the bottom left side of the air compressor 3, with the bottom end of the flow meter 4 connected to the delivery pipe 5. A valve 6 is fixedly connected to the rear end of the delivery pipe 5, and a connecting pipe 7 is connected to the rear end of the valve 6. A connecting shell 8 is connected to the rear end of the connecting pipe 7, and multiple nozzles 9 are equidistantly connected to the top wall of the connecting shell 8. When the valve 6 is opened, the high-pressure airflow is output through the connecting shell 8 and the multiple nozzles 9, thereby forming continuous bubbles. This alters the surrounding flow field, and under continuous aeration, the water flow forms a vertical circulation on both sides of the bubble curtain. Consequently, sediment is confined to the turbid water side under the action of the circulation, achieving interception. The effect of mud and sand is that the bottom of the connecting shell 8 is fixedly connected to the base 10. The top left and right sides of the base 10 are provided with limit components. The front and rear sides of the fixed plate 1 are provided with installation components. The left side of the base 10 is provided with the connecting mechanism 2. The limit component includes two threaded rods 11. The bottom ends of the two threaded rods 11 are rotatably connected to the left and right sides of the top wall of the base 10, respectively. The top of the threaded rods 11 is fixedly connected to the turntable 12. Under the rotation of the turntable 12, the threaded rods 11 can complete the rotation. Thus, the lifting plate 13 is restricted to rotate by the limit cone 14. The outer wall of the threaded rod 11 is threadedly connected to the lifting plate 13. The front and rear sides of the bottom wall of the lifting plate 13 are fixedly connected to the limit cone 14. The lifting plate 13 will not rotate with the threaded rod 11, thereby achieving the purpose of driving the limit cone 14 to rise and fall, thereby improving the stability of the device during use. The middle parts of the multiple limit cones 14 are respectively slidably connected to the inside of the base 10.

[0040] Specifically, an air compressor 3 is fixedly installed on the top wall of the fixed plate 1. When the air compressor 3 is working, it generates compressed airflow, which is used to monitor the airflow rate through the connection of the flow meter 4. The bottom end of the air compressor 3 is connected to the delivery pipe 5 to transmit the airflow. The rear end of the delivery pipe 5 is connected to the valve 6, which can control the flow of airflow. When the valve 6 is open, the airflow enters the connecting pipe 7 connected to the rear end through the delivery pipe 5, and is then transmitted to the connecting shell 8 through the connecting pipe 7. The top wall of the connecting shell 8 is connected to multiple nozzles 9, which spray out high-pressure airflow to form continuous bubbles. These bubbles can change the surrounding flow field. Under the action of continuous aeration, the water flow forms a vertical circulation on both sides of the bubble curtain. Using the force of this circulation, the sediment is restricted to the turbid water side, realizing the sediment interception function. The base 10 fixedly connected to the bottom of the connecting shell 8 provides a supporting foundation for the entire device. The limiting components on the left and right sides of the top of the base 10 are composed of two threaded rods 11. The bottom ends of the threaded rod 11 are rotatably connected to the left and right sides of the top wall of the base 10. The turntable 12 fixed at the top facilitates manual rotation of the threaded rod 11 by the operator. The outer wall of the threaded rod 11 is threadedly connected to the lifting plate 13. The limiting cones 14 fixed on the front and rear sides of the bottom wall of the lifting plate 13 slide in cooperation with the inside of the base 10. Under the restriction of the limiting cones 14, the lifting plate 13 will not rotate with the threaded rod 11, but can only move along the axial direction of the threaded rod 11. By rotating the turntable 12, the threaded rod 11 is rotated, thereby realizing the lifting of the lifting plate 13, which in turn drives the limiting cones 14 to rise and fall, so that the limiting cones 14 can be inserted into or removed from the ground, enhancing the stability of the device during use and ensuring that the device remains stable when intercepting mud and sand. At the same time, the mounting components set on the front and rear sides of the fixed plate 1 are used to connect and fix the fixed plate 1 to the external structure. The connecting mechanism 2 set on the left side of the base 10 is used to connect and cooperate with other related equipment or components.

[0041] Reference Figure 1 , Figure 3 and Figure 5 The connecting mechanism 2 includes two mounting plates 201. The right sides of the two mounting plates 201 are fixedly connected to the front and rear ends of the left side of the base 10. The front and rear ends of the right side of the base 10 are provided with mounting grooves 202. By engaging the mounting plates 201 with the mounting grooves 202, the base 10 completes the initial engagement during connection. The left side of the mounting plates 201 engages with the mounting grooves 202. The front and rear ends of the right side of the top wall of the base 10 are rotatably connected with locking plates 203. Subsequently, as the locking plates 203 rotate, they can lock with the corresponding locking grooves 204. The front and rear ends of the left side of the top wall of the base 10 are provided with locking grooves 204. The bottom of the locking plates 203 engages with the locking grooves 204, thereby improving the connection effect when the base 10 is connected. The left side of the connecting shell 8 is connected to a connecting valve 208. The rear side of the base 10 is provided with a snap-fit ​​assembly.

[0042] Specifically, two mounting plates 201 are fixedly connected to the front and rear ends of the left side of the base 10, and mounting slots 202 are opened at the front and rear ends of the right side. When the base 10 is spliced, the mounting plates 201 and mounting slots 202 of adjacent base 10 engage with each other to achieve initial positioning and fixation. The left side of the mounting plate 201 is embedded in the mounting slot 202 to restrict the relative displacement of the base 10 in the horizontal direction. A locking plate 203 is rotatably connected to the front and rear ends of the right side of the top wall of the base 10, and a locking slot 204 is opened at the front and rear ends of the left side. The locking plate 203 is rotated around its rotation connection point so that its bottom is engaged in the corresponding locking slot 204. Through this engaging structure, the connection between adjacent base 10 is further strengthened, preventing the spliced ​​base 10 from loosening and separating, and effectively improving the overall stability and reliability of the base 10 when connected. In addition, the connecting valve 208 connected to the left side of the connecting shell 8 is used to connect other equipment and provide an interface for gas transmission function, which facilitates the expansion connection of the device according to actual use needs.

[0043] Reference Figure 3 , Figure 4 and Figure 5 The snap-fit ​​assembly includes multiple snap-fit ​​posts 205, and multiple snap-fit ​​grooves 206 are equidistantly provided on the rear side of the base 10. The rear ends of the snap-fit ​​posts 205 engage with the snap-fit ​​grooves 206. The connecting mechanism 2 also includes a sealing ring 209. The inner wall of the sealing ring 209 is fixedly connected to the outer wall of the connecting valve 208, and the outer wall of the sealing ring 209 is fixedly connected to the left side of the connecting shell 8. Rubber rings 207 are fixedly connected to the outer walls of the two mounting plates 201. A control switch 15 is fixedly connected to the right side of the top wall of the fixing plate 1. The control switch 15 is electrically connected to the air compressor 3, the flow meter 4, and the valve 6, respectively.

[0044] Specifically, the engagement of the snap-fit ​​post 205 and the snap-fit ​​groove 206 enables the device to be longitudinally spliced, increasing the length of the water vapor curtain. Under the connection of the sealing ring 209, the sealing performance between the connecting valve 208 and the connecting shell 8 is improved. Through the control switch 15, which is electrically connected to the air compressor 3, the flow meter 4 and the valve 6 respectively, the control switch 15 can complete the opening and closing of the equipment.

[0045] Reference Figure 1 , Figure 2 and Figure 3 The mounting assembly includes multiple mounting bases 16, with each adjacent side of the mounting bases 16 fixedly connected to the outer wall of the fixing plate 1. The top wall of the mounting base 16 is provided with mounting holes 17. Side baffles 19 are fixedly connected to the top of both the left and right sides of the connecting shell 8, and rubber rings 18 are fixedly connected to the front end of the outer wall of the connecting pipe 7.

[0046] Specifically, the connection between the mounting base 16 and the mounting hole 17 facilitates the flexible installation of the fixing plate 1, the side baffle 19 reduces the damage of mud and sand on the left and right sides to the nozzle 9, and the rubber ring 18 protects the connection point at the front end of the connecting pipe 7.

[0047] Working principle: After the air compressor 3 starts, the high-pressure airflow output first passes through the flow meter 4 installed on the bottom left side to monitor the flow rate, and then is transmitted through the delivery pipe 5 connected to the bottom. The valve 6 at the rear end of the delivery pipe 5 controls the airflow. After the valve 6 is opened, the airflow passes through the connecting pipe 7 and the connecting shell 8 in sequence, and is finally output by multiple nozzles 9 evenly distributed on the top wall of the connecting shell 8, forming a continuous bubble flow. As these continuously released bubbles rise, they change the flow field of the surrounding water. The water carries the bubbles upward to the water surface and then disperses to both sides, forming a surface horizontal flow. Subsequently, under the action of continuous aeration, vertical circulation is generated on both sides of the bubble curtain. The force generated by the circulation will lift the mud. The sand is confined to the muddy water side to prevent silt from spreading to the waterway area and ensure normal navigation of ships. The base 10 fixed at the bottom of the connecting shell 8 provides support for the device. The limiting components on the left and right sides of the top of the base 10 are composed of a threaded rod 11 rotatably connected to its top wall, a turntable 12 at the top, a lifting plate 13 threadedly connected to the threaded rod 11, and a limiting cone 14 on the bottom wall of the lifting plate 13. Rotating the turntable 12 drives the threaded rod 11 to rotate. Because the limiting cone 14 slides in the base 10, it restricts the rotation of the lifting plate 13, so that it can only move along the axial direction of the threaded rod 11, thereby realizing the lifting and lowering of the limiting cone 14, inserting it into the soil or removing it from the soil, and enhancing the stability of the device during use.

[0048] Furthermore, when splicing the two bases 10, the mounting plate 201 fixedly connected to the front and rear ends of the left side of one base 10 engages with the mounting groove 202 of the other base 10, thus achieving initial positioning and fixation of the two bases 10. After the initial engagement is completed, the locking plate 203 is flipped to rotate around the rotating connection point, and the bottom of the locking plate 203 is engaged into the corresponding locking groove 204 on the front and rear ends of the left side of the top wall of the base 10. This engagement and locking structure further enhances the connection strength between adjacent bases 10, prevents the bases 10 from loosening and separating during use, and effectively improves the overall stability of the bases 10 after splicing. Subsequently, the connecting valve 208 can connect to other connecting shells 8. After connecting different connecting shells 8 to each other through the connecting valve 208, the nozzles 9 on the top walls of multiple connecting shells 8 can work together, which is convenient for setting up multi-layer bubble curtains. Compared with single-layer bubble curtains, multi-layer bubble curtains generate a wider range and greater intensity of flow field and vertical circulation, which can more effectively confine sediment to the turbid water area, thereby improving the sediment interception effect and meeting the sediment interception needs in different scenarios.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
