Description

Technical Field

[0001] This utility model relates to the field of water conservancy equipment technology, and in particular to an anti-buoyancy water collection weir device. Background Technology

[0002] As a crucial hydraulic facility, the core function of a catchment weir is to precisely intercept water flow and guide it along a predetermined path, thereby efficiently achieving the goal of water resource collection or diversion. Generally, a catchment weir system consists of two main parts working together: a retaining weir and an overflow weir. The retaining weir plays a vital role in flexibly regulating water levels, while the overflow weir acts as a safety barrier, effectively preventing flooding and overflow. When designing and constructing a catchment weir, multiple factors such as topography, geological conditions, hydrological characteristics, and meteorological changes must be comprehensively considered to ensure its safe, stable, and efficient operation.

[0003] In the operation of water tanks or related water treatment facilities, weirs exhibit unique flow guidance and drainage functions, especially when the water level rises to overflow height, enabling them to quickly respond and activate the drainage mechanism. However, when the water tank is empty and begins to fill, as the water level gradually rises until it touches the bottom plate of the weir, the buoyancy effect will increase dramatically. During this process, the contact points between the weir and the two side walls of the tank will bear enormous pressure. Over time, this can easily lead to loosening, detachment, or deformation of the structural connections, thus posing a serious threat to the stability of the entire equipment. In addition, in existing technologies, the overall length of the structure on the weir used to block the water flow cannot be adjusted according to the pressure exerted by the water flow. When the water flow pressure changes, if the length of the structure blocking the water flow cannot be adjusted, it may lead to excessive stress in some parts of the structure while other parts experience less stress, resulting in uneven stress. Over time, this uneven stress will accelerate fatigue damage to the structure and may even cause structural failure.

[0004] Furthermore, we disclose an anti-buoyancy water collection weir device to solve the problems in the prior art where the structural connections are prone to loosening, falling off or deforming due to the buoyancy effect during water intake, and the structural length that blocks the water flow cannot be adjusted according to the water flow pressure, resulting in uneven stress, accelerated structural fatigue damage or even structural failure. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose an anti-buoyancy water collection weir device to solve the problems in the prior art where the structural connection is prone to loosening, falling off or deforming due to the buoyancy effect during water intake, and the structural length that blocks the water flow cannot be adjusted according to the water flow pressure, resulting in uneven stress, accelerated structural fatigue damage or even structural failure.

[0006] To achieve the above objectives, this utility model provides an anti-buoyancy water collection weir device, comprising a base plate, wherein a plurality of anti-buoyancy holes are evenly spaced in the middle of the base plate, the anti-buoyancy holes being used to reduce the buoyancy force of water on the base plate, a weir plate being fixedly connected to both ends of one end face of the base plate, the weir plate being U-shaped, baffles being provided on both sides of the base plate, and sliding plates being slidably connected to both ends of the base plate, a baffle being rotatably connected to the end of the sliding plate away from the base plate, and a fixing block being rotatably connected to one end of the baffle.

[0007] Preferably, the spacing between the anti-floating holes is 2 to 3 times the hole diameter.

[0008] Preferably, both ends of the base plate are provided with opening slots, the slide plate is slidably connected to the base plate through the opening slots, and an anti-spring is fixedly connected to the middle of the side face of the slide plate near the base plate. The end of the anti-spring away from the slide plate is fixedly connected to the inner sidewall of the opening slot.

[0009] Preferably, a bonding plate is fixedly connected to the side of the fixing block away from the baffle, and the side of the bonding plate away from the bottom plate is in contact with the inner wall of the weir plate.

[0010] Preferably, the bonding plate is a rubber plate.

[0011] Preferably, a fixing plate is fixedly connected to both ends of one side end face of the base plate, a telescopic spring is fixedly connected to the side end face of the fixing plate near the baffle, a mounting base is fixedly connected to one end of the telescopic spring, a ball sleeve is fixedly connected to the middle of the side of the mounting base near the baffle, a ball head is rotatably connected inside the ball sleeve, a slider is fixedly connected to the end of the ball head away from the ball sleeve, a sliding groove is opened in the middle of the baffle, and the end of the slider away from the ball head is slidably connected inside the sliding groove.

[0012] The beneficial effects of this utility model are:

[0013] This anti-buoyancy weir device creates multiple anti-buoyancy holes at even intervals in the middle of the base plate. When the water level rises to the height of the anti-buoyancy holes, the water flows through the holes to form a pressure relief channel that connects the inside and outside, reducing the water pressure below the base plate. This reduces the vertical upward component of buoyancy on the weir, effectively alleviating the shear stress between the weir and the pool wall, preventing the structure from deforming or falling off due to excessive buoyancy. This significantly improves the structural stability and reliability of the weir device in response to water level changes, and solves the structural safety hazards caused by buoyancy problems in existing technologies.

[0014] This device, through the sliding connection between the sliding plate and the opening groove, the elastic action of the contact spring, and the cooperation of the telescopic spring, ball sleeve, ball head, slider, and groove, allows the baffle to flexibly adjust the length of the overall water-blocking structure according to changes in water pressure. When the water pressure increases, the baffle can overcome the spring force and slide outward, increasing the water-blocking length; when the water pressure decreases, the baffle slides inward under the action of the spring force, shortening the water-blocking length. This adjustment mechanism enables the water collection weir to better adapt to different water pressures, ensure uniform stress on the structure, reduce structural damage caused by uneven stress, improve the performance and lifespan of the water collection weir device under different working conditions, and effectively solve the defect of existing water-blocking structures that cannot adapt to changes in water pressure.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0023] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

[0024] like Figures 1 to 4 As shown, an anti-buoyancy water collection weir device includes a base plate 2. Multiple anti-buoyancy holes 1 are evenly spaced in the middle of the base plate 2. The anti-buoyancy holes 1 are used to reduce the buoyancy of the water on the base plate 2. Weir plates 3 are fixedly connected to both ends of one end face of the base plate 2. The weir plates 3 are U-shaped. Baffles 6 are provided on both sides of the base plate 2. Slide plates 7 are slidably connected to both ends of the base plate 2. The end of the slide plate 7 away from the base plate 2 is rotatably connected to the baffle 6. A fixing block 5 is rotatably connected to one end of the baffle 6. The spacing between the anti-buoyancy holes 1 is 2 to 3 times the hole diameter.

[0025] The anti-buoyancy weir device effectively reduces the impact of buoyancy on the bottom plate 2: when the water level rises to the height of the anti-buoyancy holes 1, the water flow can smoothly pass through the multiple anti-buoyancy holes 1 evenly spaced in the middle of the bottom plate 2, forming a pressure relief channel that connects the inside and outside. This design significantly reduces the water pressure below the bottom plate 2, thereby reducing the vertical upward component of buoyancy on the weir. In this way, the shear stress between the weir and the pool wall is effectively relieved, avoiding structural deformation or detachment caused by excessive buoyancy, thus significantly improving the overall stability and safety of the weir device.

[0026] Furthermore, such as Figures 3 to 4 As shown, both ends of the base plate 2 are provided with opening slots 13. The slide plate 7 is slidably connected to the base plate 2 through the opening slots 13. A contact spring 14 is fixedly connected to the middle of the end face of the slide plate 7 near the base plate 2. The end of the contact spring 14 away from the slide plate 7 is fixedly connected to the inner wall of the opening slot 13. A bonding plate 16 is fixedly connected to the side of the fixing block 5 away from the baffle 6. The side of the bonding plate 16 away from the base plate 2 is in contact with the inner wall of the weir plate 3. The bonding plate 16 is a rubber plate.

[0027] This anti-buoyancy weir device achieves the function of adjusting the overall length of the water-retaining structure according to the water flow pressure: the opening slots 13 at both ends of the base plate 2 are slidably connected to the sliding plate 7, providing a movable support base for the sliding plate 7; the anti-collision spring 14 fixed in the middle of the end face of the sliding plate 7 near the base plate 2 has one end fixedly connected to the inner wall of the opening slot 13, and the elastic force of the spring makes the sliding plate 7 tend to move to both sides, but can remain stable within a certain range; when the water flow pressure changes, the water flow exerts a force on the baffle 6, and the baffle 6 drives the sliding plate 7 to overcome the anti-collision through the rotation connection. The spring 14 slides along the opening groove 13, thereby changing the distance between the two baffles 6, and thus adjusting the length of the water-blocking structure formed by the baffles 6, the sliding plate 7, and the base plate 2. At the same time, the bonding plate 16 fixed on the side of the fixing block 5 away from the baffle 6 contacts the inner wall of the weir plate 3. During the adjustment process, the bonding plate 16 can slide along the inner wall of the weir plate 3. The bonding plate 16 is a rubber plate, which not only plays a certain sealing role, but also ensures the stability of the adjustment process, so that the length of the overall water-blocking structure can be flexibly adjusted according to the change of water pressure to adapt to different working conditions.

[0028] Furthermore, such as Figure 2 As shown, a fixing plate 4 is fixedly connected to both ends of one side end face of the base plate 2. A telescopic spring 8 is fixedly connected to the side end face of the fixing plate 4 near the baffle 6. A mounting base 9 is fixedly connected to one end of the telescopic spring 8. A ball sleeve 10 is fixedly connected to the middle of the side of the mounting base 9 near the baffle 6. A ball head 11 is rotatably connected inside the ball sleeve 10. A slider 12 is fixedly connected to the end of the ball head 11 away from the ball sleeve 10. A groove 15 is opened in the middle of the baffle 6. The end of the slider 12 away from the ball head 11 is slidably connected inside the groove 15.

[0029] The anti-buoyancy weir device improves the rotational stability of the baffle 6 through the following structural cooperation: On the fixed plate 4 fixedly connected to both ends of one side end face of the base plate 2, a telescopic spring 8 is fixed on the side end face near the baffle 6. One end of the telescopic spring 8 is connected to the mounting base 9. A ball sleeve 10 is provided in the middle of the side of the mounting base 9 near the baffle 6. A ball head 11 is rotatably connected inside the ball sleeve 10. The end of the ball head 11 away from the ball sleeve 10 is connected to the slider 12. A groove 15 is opened in the middle of the baffle 6. The end of the slider 12 away from the ball head 11 is slidably connected inside the groove 15. When the baffle 6 rotates under the force of the water flow, the slider 12 slides in the groove 15. This sliding fit restricts the rotation trajectory of the baffle 6, making it only able to rotate around a specific axis. At the same time, the extension spring 8 applies a force to the mounting base 9 through its own elastic force, which is then transmitted through the ball sleeve 10, ball head 11 and slider 12 to form a certain constraint on the baffle 6. This effectively buffers the impact force of the water flow on the baffle 6, reduces the swaying and offset of the baffle 6 during rotation, and thus significantly improves the stability of the baffle 6 rotation.
