Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a gate opening and closing force balancing and adjusting device for water conservancy projects. Background Technology

[0002] Gates are commonly used in water conservancy projects. They are control facilities used to close and open water discharge channels and are an important part of hydraulic structures. They can be used to intercept water flow, control water level, regulate flow, and discharge silt and floating objects. Therefore, gate drive devices are needed in water conservancy projects to meet the usage requirements.

[0003] Patent document CN221741180U discloses a flood control gate for water conservancy projects, including a concrete layer and a fixing plate fixed inside it, and further including: an installation groove opened inside the fixing plate, and a rotating valve connected to the top of the fixing plate; while the gate plate moves downward, the gate plate is supported by a support mechanism and a wedge block, thereby improving the gate plate's ability to resist water flow, and solving the problems of current flood control gates being inconvenient to clean foreign objects and having poor flood control effect.

[0004] The flood control gates for water conservancy projects proposed in the above patent documents, like some valves in existing technology, use a screw drive to raise and lower the gate for opening and closing. However, the screw's long-term contact with water and air can easily cause corrosion and wear on its surface, leading to uneven force distribution during gate opening and closing, and reducing the smoothness and stability of the gate's raising and lowering process. Therefore, it is necessary to improve the existing valves used in water conservancy projects. Utility Model Content

[0005] This utility model discloses a gate opening and closing force balancing and adjusting device for water conservancy projects. To achieve the above objectives, this utility model adopts the following technical solution:

[0006] A gate opening and closing force balancing and adjusting device for water conservancy projects includes a gate frame, a gate body slidably disposed on the inner side of the gate frame, a support frame fixedly connected to the top of the gate frame, a protective shell fixedly connected to the upper surface of the support frame, and a lifting mechanism and a lubrication mechanism disposed inside the protective shell.

[0007] The lifting mechanism is used to drive the gate body to lift and open / close. The lifting mechanism includes two winding reels rotatably connected to the inner wall of the protective shell. A steel cable is wound around the surface of the winding reel. The end of the steel cable away from the winding reel extends to the outside of the protective shell and is fixedly connected to the upper surface of the gate body.

[0008] The lubrication mechanism is used to lubricate the surface of the steel cable. The lubrication mechanism includes an oil spray pipe fixedly connected to the inner wall of the protective shell, and an oil spray nozzle is fixedly embedded on the surface of the oil spray pipe.

[0009] A drive box is fixedly connected to the back of the protective shell. The drive box contains a drive mechanism that drives the two winding reels to rotate in opposite directions.

[0010] In a preferred embodiment, the inner wall of the protective shell is rotatably connected to two guide wheels, the steel cable is slidably connected to the surface of the guide wheels, and the lower surface of the support frame has two through holes, the positions of which correspond to the steel cable.

[0011] In a preferred embodiment, an oil reservoir is fixedly connected to the inner wall of the protective shell, and an injection pump is fixedly installed on the side of the oil reservoir. The input end of the injection pump extends into the interior of the oil reservoir, and the output end of the injection pump is fixedly connected to an oil guide pipe. The end of the oil guide pipe away from the injection pump extends into the interior of the injection pipe.

[0012] In a preferred embodiment, the drive mechanism includes a drive motor fixedly mounted on the inner wall of the drive housing, a transmission rod fixedly connected to the output shaft of the drive motor, two worm gears fixedly connected to the surface of the transmission rod, a linkage shaft fixedly provided on the surface of the take-up reel, one end of the linkage shaft extending into the interior of the drive housing and fixedly connected to a worm wheel.

[0016] As can be seen from the above, the hydraulic engineering gate opening and closing force balancing adjustment device provided by this utility model has the following technical effects.

[0017] Firstly, the top of the gate in the water conservancy project is equipped with a lifting mechanism. When opening and closing the gate, the drive motor can drive two worm gears with opposite threads to rotate, which in turn drives two winding reels to rotate in opposite directions. The two winding reels are then used to wind up and unwind the steel cable, achieving simultaneous raising and lowering of the gate. This ensures that the top of the gate is subjected to a balanced tension, improving the smoothness and stability of the gate during the raising, lowering, opening, and closing process.

[0018] Secondly, by setting up a lubrication mechanism inside the protective shell, the lubricating oil in the oil storage box can be input into the oil spray pipe by the oil injection pump, and then the oil spray nozzle on the surface of the oil spray pipe can be used to spray oil onto the surface of the steel cable, so that the steel cable is kept lubricated during contact with the guide wheel, improving the smoothness of the steel cable during the moving and winding process, realizing the protection of the steel cable, and helping to improve the service life of the steel cable.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1 and Figure 2A gate opening and closing force balancing and adjusting device for water conservancy projects includes a gate frame 1, a gate body 2 slidably disposed on the inner side of the gate frame 1, a support frame 3 fixedly connected to the top of the gate frame 1, a protective shell 4 fixedly connected to the upper surface of the support frame 3, and a lifting mechanism 5 and a lubrication mechanism 6 disposed inside the protective shell 4.

[0030] It should be noted that two limiting scrapers 10 are fixedly connected to the left and right inner sides of the gate frame 1. The limiting scrapers 10 are symmetrically distributed on the front and rear sides of the gate body 2. Several scraping through holes 11 are opened on the surface of the limiting scrapers 10. The several scraping through holes 11 are distributed in a straight line and perpendicularly on the surface of the limiting scrapers 10.

[0031] It is worth noting that by setting the limiting scraper 10, not only can the gate body 2 be moved and limited by the limiting scraper 10, but the debris adsorbed on both sides of the gate body 2 can also be scraped off by the limiting scraper 10, and the scraped impurities can be discharged by the scraping through hole 11, so as to avoid the blockage between the two sides of the gate body 2 and the gate frame 1 and improve the smoothness of the gate opening and closing.

[0032] Reference Figure 3 In a preferred embodiment, the lifting mechanism 5 is used to drive the gate body 2 to lift and open / close. The lifting mechanism 5 includes two winding reels 501 rotatably connected to the inner wall of the protective shell 4. A steel cable 502 is wound around the surface of the winding reel 501. One end of the steel cable 502 away from the winding reel 501 extends to the outside of the protective shell 4 and is fixedly connected to the upper surface of the gate body 2.

[0033] It is worth noting that a lifting mechanism 5 is installed at the top of the water conservancy project gate. When opening and closing the gate, the drive motor 801 can drive the two reverse-threaded worm gears 803 to rotate, which in turn drives the two worm wheels 805 to rotate. The two worm wheels 805 drive the two winding reels 501 to rotate in opposite directions through the linkage shaft 804. The two winding reels 501 are then used to wind up and unwind the steel cable 502, realizing the simultaneous lifting and lowering of the gate. This ensures that the top of the gate is subjected to a balanced tension, improving the smoothness and stability of the gate during the lifting, opening and closing process.

[0034] Reference Figure 5 In a preferred embodiment, the lubrication mechanism 6 is used to lubricate the surface of the steel cable 502. The lubrication mechanism 6 includes an oil spray pipe 601 fixedly connected to the inner wall of the protective shell 4. An oil spray nozzle 602 is fixedly embedded on the surface of the oil spray pipe 601. The oil spray nozzle 602 faces the position of the steel cable 502 and the guide wheel 503, so that the oil spray nozzle 602 sprays lubricating oil onto the surface of the steel cable 502 and the guide wheel 503, so that the steel cable 502 can maintain smooth movement.

[0035] It should be noted that an oil reservoir 603 is fixedly connected to the inner wall of the protective shell 4, and an injection pump 604 is fixedly installed on the side of the oil reservoir 603. The input end of the injection pump 604 extends into the interior of the oil reservoir 603, and an oil guide pipe 605 is fixedly connected to the output end of the injection pump 604. The end of the oil guide pipe 605 away from the injection pump 604 extends into the interior of the injection pipe 601.

[0036] It is worth noting that by setting a lubrication mechanism 6 inside the protective shell 4, the lubricating oil in the oil storage box 603 can be input into the oil spray pipe 601 through the oil guide pipe 605 by the oil injection pump 604. Then, the oil spray nozzle 602 on the surface of the oil spray pipe 601 sprays oil onto the surface of the steel cable 502, so that the steel cable 502 remains lubricated during contact with the guide wheel 503. At the same time, it can improve the smoothness of the steel cable 502 during the moving and winding process, play a protective role for the steel cable 502, and help to improve the service life of the steel cable 502.

[0037] It should be noted that a drive box 7 is fixedly connected to the back of the protective shell 4. The drive box 7 contains a drive mechanism 8, which is used to drive the two winding reels 501 to rotate in opposite directions.

[0038] Reference Figure 4 In a preferred embodiment, the drive mechanism 8 includes a drive motor 801 fixedly mounted on the inner wall of the drive housing 7. The output shaft of the drive motor 801 is fixedly connected to a transmission rod 802. Two worm gears 803 are fixedly connected to the surface of the transmission rod 802. A linkage shaft 804 is fixedly provided on the surface of the take-up reel 501. One end of the linkage shaft 804 extends into the interior of the drive housing 7 and is fixedly connected to a worm wheel 805. The position of the worm wheel 805 corresponds to that of the worm gear 803. The worm gear 803 meshes with the worm wheel 805, and the thread directions on the surfaces of the two worm gears 803 are opposite to each other. By utilizing the opposite threads of the two worm gears 803, while the two worm gears 803 rotate in the same direction, the two worm wheels 805 meshing with them can be driven to rotate in the opposite direction. Thus, the take-up reel 501 can be used to perform synchronous take-up and unwinding operations of the steel cable 502.

[0039] It should be further explained that the inner wall of the protective shell 4 is rotatably connected to two guide wheels 503, and the steel cable 502 is slidably connected to the surface of the guide wheels 503. The lower surface of the support frame 3 has two through holes 9, the positions of which correspond to the steel cable 502. The steel cable 502 extends from the inside of the protective shell 4 to the top of the gate body 2 below through the through holes 9.

[0040] Working principle: When opening the gate, the drive motor 801 first drives the transmission rod 802 to rotate, which in turn drives the two worm gears 803 to rotate. The two worm gears 803 drive the two worm wheels 805 and the linkage shaft 804 to rotate, which in turn drives the two winding reels 501 to wind up the steel cable 502. The two steel cables 502 drive the gate body 2 to move upward inside the gate frame 1, thereby opening the gate. While the gate body 2 is rising or falling, the limiting scrapers 10 on the front and rear sides can limit the gate body 2 to prevent it from swaying back and forth, thus improving the stability of the gate body 2 during opening and closing.

[0041] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
