Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy construction technology, and in particular to a concrete pouring anti-segregation device for water conservancy construction. Background Technology
[0002] Hydraulic construction refers to a series of construction activities carried out during the construction of water conservancy projects. These activities aim to build, renovate, and maintain water conservancy facilities, including dams, reservoirs, rivers, irrigation and drainage systems, hydroelectric power stations, pumping stations, and water treatment plants. They are mainly used for various purposes such as water resource development and utilization, flood control, irrigation, hydroelectric power generation, water supply, and drainage. Concrete pouring refers to the process in building construction of pouring and filling pre-mixed concrete into pre-designed molds and structural parts using specific methods. It is a crucial step in concrete structure construction, involving the transportation of concrete materials from mixers and transport vehicles to the target location on the construction site, ensuring that the concrete is evenly distributed and solidifies into the desired structural form. Anti-segregation devices are equipment used to prevent segregation of concrete during the pouring process. Segregation refers to the separation of cement paste from aggregates (such as sand and gravel) in concrete, resulting in uneven concrete, with cement paste rising and aggregates sinking. In severe cases, this can affect the quality, strength, and durability of the concrete.
[0003] Concrete anti-segregation devices improve the fluidity, cohesion, and anti-segregation properties of concrete by increasing the amount of binder and using special additives. The increased binder helps strengthen the bond between cement and aggregate, thus reducing segregation. Special additives (such as air-entraining agents, water-reducing agents, and thickeners) optimize the concrete structure, making it more homogeneous, improving its stability during pouring, preventing separation of cement paste and aggregate, and ensuring the strength and durability of the concrete.
[0004] In existing technologies, some methods to prevent concrete segregation mainly involve altering the concrete mix proportions, increasing the amount of binder, and using special additives. However, these methods often require precise adjustments to the concrete mix proportions, are complex to operate, and can affect other properties of the concrete. Furthermore, these methods cannot completely prevent concrete segregation during the pouring process. Therefore, a concrete pouring anti-segregation device for hydraulic construction is proposed to address these issues. Utility Model Content

[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, by starting the motor and rotating the column, the connected rotating roller rotates inside the outer shell, causing the concrete inside the square funnel to fall into the groove on the rotating roller, realizing the quantitative feeding of concrete and preventing its segregation. Then, it rotates and is conveyed to the inside of the connecting pipe. When passing through, the barrier column separates the concrete under force to prevent its segregation. In addition, the bottom conveying pipe is curved, thereby preventing concrete segregation again.
[0025] 2. In this utility model, the rotating column two is rotated by starting the motor two, and the rotational force is transmitted to the screen funnel through the fixed plate. Because the rotating column two is connected to the sliding block, and there are springs on both sides of the sliding block, the force generated when the screen funnel rotates will drive the sliding block to slide on the connecting plate, and the spring reaction force will cause the sliding block to drive the screen plate to vibrate, thereby remixing the concrete poured into the square funnel and preventing segregation in the early stage.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0033] Reference Figure 1 , Figure 3 , Figure 4 One embodiment of this utility model is a concrete pouring anti-segregation device for water conservancy construction, which includes a square funnel 1. The square funnel 1 is generally in the shape of a square cone with a larger top and a smaller bottom. Its shape is regular and all four sides are isosceles trapezoids. The funnel is made of a sturdy and durable metal material with good wear resistance, such as high-quality carbon steel, which can withstand the large impact force generated during the pouring of concrete and the long-term friction, and is not easily deformed or damaged. The bottom of the square funnel 1 is fixedly connected to the outer shell 2. The outer shell 2 is a hollow cuboid shape and is also made of carbon steel, consistent with the square funnel 1, to ensure the structural strength and durability of the entire device. The bottom of the outer shell 2 is fixedly connected to the connecting hopper 3, and the outside of the connecting hopper 3 is fixedly connected to the metering mechanism. The metering mechanism includes a support plate 4, which is a rectangular plate structure made of a sturdy metal material, such as carbon steel, and is fixedly connected to the outside of the outer shell 2 by welding. The outside of the support plate 4 is fixedly connected to the outside of the outer shell 2, and the top of the support plate 4 is fixedly connected to a drive component that provides rotational power.
[0034] The drive assembly includes a motor 5, which is cylindrical in shape and made of robust and well-ventilated aluminum alloy. Internally, it houses high-precision stators, rotors, windings, and bearings. These components undergo rigorous quality testing and meticulous assembly processes to ensure stable and efficient output of rotational power from the motor 5. The bottom of the motor 5 is fixedly connected to the top of the support plate 4. A rotating column 6, slender cylindrical in shape and made of high-strength alloy steel, is fixedly connected to the drive end of the motor 5. The rotating column 6 is rotatably connected to the inside of the connecting bucket 3. A rotating roller 7, also cylindrical in shape and made of a wear-resistant and corrosion-resistant metal such as stainless steel, is fixedly connected to the drive assembly. Its smooth surface is specially treated to reduce concrete adhesion. The rotating roller 7 is rotatably connected to the inside of the outer shell 2 and slidably connected to the bottom of the square funnel 1. The rotating roller 7 is externally slidably connected to the top of the connecting hopper 3. The rotating roller 7 has a groove 8 on its outside. The spiral groove 8 can make the concrete form a certain flow pattern on its surface, further enhancing the control effect of the concrete flow rate, so that the concrete can enter the connecting pipe 9 according to the predetermined flow rate and speed. The connecting pipe 9 is fixedly connected to the bottom of the connecting hopper 3. The connecting pipe 9 is a tubular structure and is made of carbon steel. The anti-segregation component is fixedly connected inside the connecting pipe 9. The anti-segregation component includes multiple barrier columns 10. The barrier columns 10 are cylindrical in shape and are made of elastic and wear-resistant rubber. When the concrete flows through the connecting pipe 9, the barrier columns 10 will have a certain obstruction and disturbance effect on the concrete, so that the various components in the concrete can be fully mixed and the segregation phenomenon caused by excessive flow rate and unstable factors in the flow process can be avoided. The barrier columns 10 are externally fixedly connected to the inside of the connecting pipe 9. The bottom of the connecting pipe 9 is fixedly connected to a bent pipe 11.
[0035] Reference Figures 1 to 3A connecting plate 12 is fixedly connected to the top of the square funnel 1. The connecting plate 12 is a flat rectangular plate structure made of a sturdy metal material, such as carbon steel. The left and right sides of the inside of the connecting plate 12 are fixedly connected to the outside of the spring 13. The inside of the sliding block 14 is rotatably connected to the outside of the rotating column 16. A vibration mechanism is slidably connected inside the connecting plate 12. The vibration mechanism includes the sliding block 14, which is a block structure made of a high-quality and wear-resistant metal material, such as carbon steel. The outside of the sliding block 14 is slidably connected to the inside of the connecting plate 12. Springs 13 are fixedly connected to the left and right sides of the sliding block 14. The springs 13 and the sliding block 14 together form an elastic vibration system. When the sliding block 14 is subjected to an external force, it will reciprocate under the elastic force of the spring 13. The vibration is transmitted to the square funnel 1 through the sliding block 14, which in turn causes the concrete in the square funnel 1 to vibrate accordingly, promoting the flow and mixing of the concrete. A power component that provides rotational force is fixedly connected to the top of the sliding block 14.
[0036] The power assembly includes a second motor 15, which is cylindrical in shape and made of robust and well-ventilated aluminum alloy. Internally, it houses a high-precision stator, rotor, windings, and bearings. The bottom of the second motor 15 is fixedly connected to the top of the sliding block 14. A rotating column 16, slender and cylindrical in shape, is made of high-strength alloy steel. The bottom of the rotating column 16 is fixedly connected to the top of a fixed plate 17. The power assembly is also fixedly connected to the fixed plate 17, which is... The disc-shaped structure is made of a metal material with good strength and toughness, such as carbon steel. A screen funnel 18 is fixedly connected to the top of the fixed disc 17. The screen funnel 18 is shaped like a funnel with a larger top and a smaller bottom. It is made of a metal material with strength and wear resistance, such as stainless steel. The inner wall of the screen funnel 18 has multiple holes, which can screen and redistribute large aggregate particles in the concrete, making the concrete more uniform before entering the bottom of the square funnel 1. The inside of the square funnel 1 is rotatably connected to the outside of the fixed disc 17, and the inside of the square funnel 1 is fixedly connected to the outside of the screen funnel 18.
[0037] Working principle: First, concrete is poured into square funnel 1. Due to the funnel's own weight and shape, the concrete will naturally flow downwards. Motor 2 15 starts, driving sliding block 14 to reciprocate through rotating column 2 16. Sliding block 14 transmits vibration to square funnel 1 via spring 13, causing the concrete to vibrate within the funnel, promoting its flow and mixing. During this process, the screening funnel 18 adjusts the distribution of large aggregate particles in the concrete, making the concrete more uniform.
[0038] Then, motor 5 starts, driving rotating roller 7 to rotate via rotating column 6. The spiral grooves 8 on rotating roller 7 push concrete into connecting hopper 3 at a predetermined flow rate and speed, and then into connecting pipe 9. As the concrete flows through connecting pipe 9, barrier columns 10 obstruct and disturb the concrete, ensuring thorough mixing of its components and preventing segregation due to excessive flow rate and instability. Finally, the concrete flows through connecting pipe 9 into curved pipe 11, again preventing segregation, and is then poured into the designated location. Throughout the process, quantitative concrete feeding and control of the concrete flow effectively prevent segregation and improve the quality of concrete pouring.
[0039] 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.
