Description

Technical Field

[0001] This utility model relates to the technical field of floating barrier boxes in water conservancy projects, specifically to a steel structure floating barrier box for water conservancy projects. Background Technology

[0002] Floating barriers for water conservancy projects are specialized devices used to intercept floating objects in rivers, reservoirs, and other water bodies. They are typically made of high-strength, corrosion-resistant materials and are interconnected to form a barrier. The floating barriers can float on the water surface by their own buoyancy and use the gaps between the boxes or the box body to block floating branches, plastic waste, and other debris in specific areas for subsequent centralized dredging and cleaning, ensuring unobstructed water flow and protecting the normal operation of water conservancy facilities and the cleanliness of the water environment.

[0003] A search revealed Chinese Patent Publication No. CN222575429U, which discloses a steel structure floating barrier for hydraulic engineering. The floating barrier includes gate piers positioned on both sides of a river and a steel structure floating barrier positioned between the two gate piers for intercepting floating debris. By using this structure, the steel structure floating barrier can float vertically up and down to intercept drifting objects, thus improving the floating barrier's efficiency.

[0004] Existing technologies often have the following problems when used:

[0005] Currently, the floating barriers used in water conservancy projects are usually fixed structures. However, the direction of water flow and the distribution of floating objects in rivers vary greatly. Fixed-structure floating barriers cannot freely adjust their interception direction and angle, resulting in poor interception effectiveness. Furthermore, when facing floating objects of different depths in water, the floating barriers often only support floating up and down with the water level to intercept them, and cannot quickly and actively adjust their draft, resulting in low interception efficiency. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a steel structure floating barrier box for water conservancy projects, which can effectively solve the problems that the fixed structure of the floating barrier box in the existing technology is difficult to freely adjust the interception direction and angle, resulting in poor interception effect, and the floating barrier box cannot quickly and actively adjust the draft, resulting in low interception efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides a steel structure floating caisson for hydraulic engineering, comprising:

[0009] The central pontoon and two side pontoons are all composed of a steel frame and a floating net, and the side walls of the central pontoon and the two side pontoons are provided with interception openings.

[0010] Two steering adjustment assemblies, each of which includes two electric push rods fixedly installed on the outer wall of the central pontoon, the output ends of the two electric push rods being fixedly connected to hinge seats, two transverse slide rails being fixedly connected to the outer wall of the side pontoon, and T-shaped rotating blocks being slidably connected to the inner sides of the two transverse slide rails, with the two T-shaped rotating blocks being rotatably connected to the two hinge seats respectively.

[0011] A top plate is fixedly connected to the upper surface of the central pontoon, and a depth adjustment component is fixedly connected to the upper surface of the top plate.

[0012] Furthermore, a fixed traction rope is fixedly connected to the upper end of the steel structure frame in the central pontoon.

[0013] Furthermore, the depth adjustment assembly includes a bearing fixedly connected to the upper end face of the top plate, an adjusting screw rotatably connected to the upper end of the bearing, a slider threadedly connected to the adjusting screw, a pressure block fixedly connected to the outer wall of the slider, and a lateral limiting strip fixedly connected to the upper end face of the top plate. The pressure block is in contact and sliding fit with the top plate and the lateral limiting strip.

[0014] Furthermore, the depth adjustment assembly also includes a servo motor fixedly mounted on the upper surface of the top plate, and the output end of the servo motor is fixedly connected to one end of the adjustment screw.

[0015] Furthermore, a counterweight is fixedly connected to the upper surface of the top plate, and the counterweight and the servo motor are evenly distributed on both sides of the upper surface of the top plate.

[0016] Furthermore, each of the two side buoy boxes is fixedly connected to a pin on its outer wall, and each of the two pins is rotatably connected to a float plate on its outer peripheral wall.

[0017] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0018] This invention includes a steering adjustment component. By controlling several electric push rods to operate independently, the output ends of these electric push rods can push or pull the corresponding hinge seats and T-shaped rotating blocks, thereby causing the side float box to rotate toward the side where the electric push rod output ends extend the shortest distance. This allows the side float box to adjust the interception direction and angle of floating objects, adapting to floating objects with different water flow directions and distribution conditions.

[0019] This invention incorporates a depth adjustment component. By driving the pressure block to move to the front or rear of the central buoy, the gravity distribution of the central buoy is altered. This causes the central buoy and the two side buoys to rotate at a certain angle underwater or above water under the buoyancy support of the float plates. This allows for rapid active draft adjustment of the barrier buoy, enabling it to intercept floating objects at different water depths and improving its interception efficiency.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Example: Refer to Figures 1 to 4 A steel structure buoy for hydraulic engineering includes: a central buoy 1, two side buoys 2, and two steering adjustment components. A fixed traction rope 11 is fixedly connected to the upper end of the steel frame 3 in the central buoy 1. Pins 19 are fixedly connected to the outer walls of both side buoys 2, and float plates 20 are rotatably connected to the outer periphery of each pin 19. The central buoy 1 and the two side buoys 2 are both composed of a steel frame 3 and a floating net 4, and interception openings 5 ​​are provided on the side walls of both the central buoy 1 and the two side buoys 2. Each steering adjustment component includes two electric push rods 6 fixedly installed on the outer wall of the central buoy 1. Hinges 7 are fixedly connected to the output ends of the two electric push rods 6. Two transverse slide rails 8 are fixedly connected to the outer walls of the side buoys 2. T-shaped rotating blocks 9 are slidably connected to the inner sides of the two transverse slide rails 8, and the two T-shaped rotating blocks 9 are rotatably connected to the two hinges 7 respectively.

[0029] By controlling several electric push rods 6 to operate independently, the output ends of several electric push rods 6 can push or pull the corresponding hinge seats 7 and T-shaped rotating blocks 9 respectively, so as to drive the side float box 2 to rotate toward the side with the shorter extension distance of the output end of the electric push rod 6, thereby adjusting the interception direction and angle of the side float box 2 on the floating object, and adapting to floating objects with different water flow directions and different distribution conditions.

[0030] Specifically, the electric actuator 6 uses model ANT-26, with a waterproof and dustproof rating of IP67M, enabling it to work stably in water. Furthermore, the electric actuator 6 is equipped with an external remote control module and a time relay, allowing multiple electric actuators 6 to operate independently via remote control.

[0031] A top plate 10 is fixedly connected to the upper end face of the central pontoon 1. A depth adjustment assembly is fixedly connected to the upper end face of the top plate 10. The depth adjustment assembly includes a bearing 12 fixedly connected to the upper end face of the top plate 10. An adjusting screw 13 is rotatably connected to the upper end of the bearing 12. A slider 14 is threadedly connected to the adjusting screw 13. A pressure block 15 is fixedly connected to the outer wall of the slider 14. A lateral limiting strip 16 is fixedly connected to the upper end face of the top plate 10. The pressure block 15 contacts and slides with the top plate 10 and the lateral limiting strip 16. The depth adjustment assembly also includes a servo motor 17 fixedly installed on the upper end face of the top plate 10. The servo motor 17 is an 80DK-M07725. The output end of the servo motor 17 is fixedly connected to one end of the adjusting screw 13. A counterweight 18 is fixedly connected to the upper end face of the top plate 10. The counterweight 18 and the servo motor 17 are evenly distributed on both sides of the upper end face of the top plate 10.

[0032] By moving the driving block 15 to the front or rear of the central pontoon 1, the gravity distribution of the central pontoon 1 is changed, so that the central pontoon 1 and the two side pontoons 2 rotate at a certain angle underwater or above water under the buoyancy support of the float plate 20. This allows for rapid active draft adjustment of the barrier box, enabling it to intercept floating objects at different water depths and improving the interception efficiency of the barrier box.

[0033] Specifically, the outer surfaces of the drive source and transmission connection components are coated with a waterproof coating to ensure the efficient operation of the floatation box in the water.

[0034] Specifically, the counterweight 18 has the same mass as the servo motor 17, so the counterweight 18 can offset the gravity exerted by the servo motor 17 on the central pontoon 1, so that the central pontoon 1 can maintain its floating stability. At the same time, the float plate 20 is rotatably connected to the side pontoon 2, which can further ensure the floating stability of the central pontoon 1 and the two side pontoon 2 on the water surface when the central pontoon 1 and the side pontoon 2 rotate towards the water or above the water, thus ensuring the efficient and stable operation of the bollard.

[0035] Specifically, the pressure block 15 is made of brass, which can have a large mass despite its small size and is corrosion resistant. When the pressure block 15 is adjusted to the front of the central buoy 1, the front of the central buoy 1 has a large gravity, which causes the central buoy 1 and the side buoy 2 to rotate towards the water at a certain angle, thereby increasing the draft of the interception port 5. Conversely, when the pressure block 15 is adjusted to the rear of the central buoy 1, the central buoy 1 and the side buoy 2 will rotate towards the surface, thereby reducing the draft of the interception port 5.

[0036] The working principle of this utility model is as follows:

[0037] In use, the central buoy 1 is first fixed in a predetermined position in the water using the fixed traction rope 11. When it is necessary to adjust the interception direction and angle of the floating object, several electric push rods 6 are controlled to operate independently, so that the output ends of the electric push rods 6 can push or pull the corresponding hinge seat 7 and T-shaped rotating block 9 respectively. Since the T-shaped rotating block 9 is rotatably engaged with the hinge seat 7 and can slide freely in the transverse slide rail 8, the side buoy 2 can be driven to rotate toward the side with the shorter extension distance of the output end of the electric push rod 6, so as to adjust the interception direction and angle of the side buoy 2 against the floating object.

[0038] If the interception depth needs to be adjusted according to the depth of the floating object, the servo motor 17 can be started. The servo motor 17 drives the adjusting screw 13 to rotate, so that the slider 14, which is threadedly connected to the adjusting screw 13, can move along the axis of the adjusting screw 13. This, in turn, drives the pressure block 15 to move, so that the pressure block 15 can be adjusted to the front or rear position of the central buoy box 1 to change the gravity distribution of the central buoy box 1. This allows the central buoy box 1 and the two side buoy boxes 2 to rotate at a certain angle underwater or above water under the buoyancy support of the float plate 20, thereby quickly realizing the active draft adjustment of the intercepting float box.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
