Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering equipment technology, specifically a device for preventing mud and sand from flowing through water and preventing floating in water conveyance pipelines, which is suitable for flood protection of water conveyance pipelines in rainy areas. Background Technology

[0002] Traditional pipeline protection measures often employ single gravity ballast or simple filter structures, which have significant drawbacks in dealing with the influx of silt and sand and buoyancy imbalance caused by high-intensity rainfall. On the one hand, conventional filter screens have coarse pore sizes (usually >20mm), which can only intercept large particles of impurities and are insufficient in retaining suspended silt with a particle size of less than 0.1mm, leading to an accelerated rate of siltation in the pipeline. On the other hand, traditional ballast methods rely on concrete counterweights, which have problems such as long construction cycles, high costs, and weak impact resistance.

[0003] Therefore, a device for preventing mud and sand from flowing through water and preventing floating is proposed to address the current shortcomings. Utility Model Content

[0004] In order to solve the problems of the prior art, this utility model provides a device for preventing mud and sand from being blocked and preventing floating in water conveyance pipelines.

[0005] The technical problem to be solved by this utility model is to overcome the defects of the above-mentioned technology and provide a device for preventing mud and sand from flowing through water and preventing floating.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is a device for preventing mud and sand from flowing through water and preventing floating in water conveyance pipelines: including a main frame and a sand-blocking net;

[0007] The main frame is a hollow cylindrical structure with openings at both ends and can be fitted onto the outer wall of the water pipeline. The sand-blocking net is connected to the end of the main frame by welding. The main frame is equipped with a reinforcing frame on the outside of the sand-blocking net.

[0008] The main frame is located inside the sand-blocking net and is detachably equipped with at least one layer of filter screen that contacts the sand-blocking net. The main frame is equipped with multiple support rods on the outside.

[0009] As an improvement, the aperture of the sand-trapping mesh is 5-10mm.

[0010] As an improvement, the mesh size of the filter screen is in the range of 80-120 mesh.

[0011] As an improvement, the main frame is provided with a plurality of limiting screws in the circumferential direction to cooperate with the filter screen.

[0012] As an improvement, the number of support rods is one, and the connection point with the main frame is located at the 180° equidistant points of the lower circumference of the main frame.

[0013] As an improvement, the support rods on both sides of the main frame are installed obliquely, and the angle between them and the axis of the main frame is 45° - 60°. The support rods at the bottom of the main frame are installed vertically.

[0014] As an improvement, the support rods are made of scaffold pipes with a diameter of 48 mm.

[0015] As an improvement, the reinforcement frame is in a "rice" shape and its ends are connected to the main frame.

[0016] The advantages of the present utility model compared with the prior art are as follows:

[0017] 1. Adopting a socket-type main frame design, it is directly fixed to the outer wall of the water conveyance pipeline through a clamp, realizing rapid installation and disassembly. This structure avoids the need for pipeline modification, significantly reduces the construction cost, and at the same time facilitates the replacement of internal components (such as filter screens) during maintenance, greatly improving the maintainability of the device.

[0018] 2. Through the setting of the "rice" - shaped reinforcement frame, multiple triangular force - bearing units are formed by cross - bracing. The water flow impact force is decomposed into multi - directional component forces and evenly transmitted to the main frame, effectively suppressing vibration, torsion and local stress concentration in the turbulent flow environment, preventing the sand - intercepting net from deforming and breaking, and significantly extending the structural life.

[0019] 3. Adopting a hierarchical filtering structure composed of a sand - intercepting net + multi - layer filter screens, realizing the hierarchical interception of large - particle sediment, floating objects and fine suspended solids, significantly improving the sewage interception capacity and interception efficiency. At the same time, through the hierarchical design, the device disperses the interception pressure, extends the life of the single - layer filter screen, reduces the blockage frequency, and reduces the maintenance cost.

[0020] 4. The inclined and vertical support rods are arranged at the bottom and on both sides of the main frame, forming triangular force - bearing units, which jointly bear the lateral force and vertical force. The inclined support rods (45° - 60°) disperse the external lateral impact, and the vertical support rods provide vertical anchoring force, preventing the device from sinking or floating due to water flow impact. Through the multi - directional force - bearing system of the support rods, combined with the bottom weight area of the water conveyance pipeline and the self - weight of the device, double anti - buoyancy protection is achieved, adapting to complex water flow environments.

[0029] To make the objectives, technical solutions, and advantages of the utility model embodiments clearer, the technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. The components of the utility model embodiments described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0030] In the description of the embodiments of the utility model, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the utility model. Furthermore, terms such as "first," "second," and "third" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] Furthermore, the use of terms such as "horizontal," "vertical," and "sag" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0032] In the description of the utility model embodiments, "a plurality of" means at least two.

[0033] In the description of the embodiments of the utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the utility model according to the specific circumstances.

[0034] As shown in the attached drawings, a device for preventing mud and sand from flowing through water and preventing floating in a water pipeline includes a main frame 1 and a sand-blocking net 2.

[0035] The main frame 1 is a hollow cylindrical structure with openings at both ends and can be fitted onto the outer wall of the water supply pipe. The main frame 1 serves as the base of the device, providing fixation and support. By directly fitting the main frame 1 onto the water supply pipe, the stable operation of components such as the sand-blocking net 2 is ensured.

[0036] Meanwhile, the hollow cylindrical main frame 1 is easy to install and disassemble with the water pipe, facilitating maintenance and replacement of other components.

[0037] During implementation, the main frame 1 is made of corrosion-resistant and wear-resistant materials, such as stainless steel, galvanized steel or high-strength plastic, to ensure long-term stability in complex water flow environments.

[0038] In practical implementation, to ensure the firmness of the connection between the main frame 1 and the water supply pipe, the main frame 1 can be fixedly installed on the water supply pipe by clamps, ensuring the firmness of the connection between the device and the water supply pipe, and ensuring the convenience of disassembly. At the same time, since the main frame 1 is sleeved on the water supply pipe, when it is necessary to maintain or replace internal components (such as filter screen 4), the main frame 1 can be easily removed for maintenance or replacement and then reinstalled, which greatly improves the maintainability of the device.

[0039] Furthermore, a rubber pad that mates with the water supply pipe can be fitted onto the inner wall of the main frame 1. The length of the rubber pad is the same as the length of the main frame 1 to avoid damage to the anti-corrosion layer of the water supply pipe during installation and use.

[0040] The sand-blocking net 2 is welded to the end of the main frame 1. The sand-blocking net 2 is welded to the end of the main frame 1 and is located at the water inlet. It is used to intercept large particles of silt and floating objects, prevent them from entering the water pipeline, reduce the risk of pipeline blockage, and ensure the flow of water.

[0041] Specifically, the aperture of the sand interception net 2 can be set according to the actual situation. In this embodiment, the aperture of the sand interception net 2 is 5-10 mm, which can effectively intercept large particulate matter, prevent it from entering the interior of the water conveyance pipeline and causing blockage, and ensure the normal passage of water flow.

[0042] The main frame 1 is provided with a reinforcement frame 3 on the outer side of the sand interception net 2. In this implementation, the reinforcement frame 3 is in a "rice" shape and its end is connected to the main frame 1. Specifically, the reinforcement frame 3 is composed of multiple reinforcement arms radiating outward from the center point to form multiple support points, thereby enhancing the overall stability and bearing capacity.

[0043] Actually, the end of the reinforcement frame 3 is connected to the main frame 1 by welding to form a rigid support system, and its connection points are distributed in the circumferential direction of the main frame 1 to ensure uniform stress.

[0044] During implementation, when the water flow impacts the sand interception net 2, the impact force is dispersed to multiple directions of the main frame 1 through the cross-support structure of the "rice" shaped reinforcement frame 3, avoiding deformation or rupture caused by local stress concentration, and restricting the bending or torsional deformation of the main frame 1 in the dynamic water flow to maintain the structural integrity.

[0045] At the same time, the reinforcement frame 3 covers the outer side of the sand interception net 2 and indirectly protects the sand interception net 2 through the connection of its end to the main frame 1. The water flow impact force first acts on the reinforcement frame 3, and the reinforcement frame 3 decomposes the impact force into component forces in multiple directions through the "rice" shaped structure and transmits them to the main frame 1 through the end connection points to reduce the direct impact on the sand interception net 2.

[0046] In addition, in a turbulent or rapid flow environment, the reinforcement frame 3 is distributed in a "rice" shaped cross pattern to form multiple triangular force-bearing units. Through the stability of the triangular force-bearing units, the vibration or swaying of the main frame 1 is inhibited, preventing structural failure caused by dynamic loads.

[0047] When floating objects or large particulate sediment accumulate on the surface of the sand interception net 2, the covering structure of the reinforcement frame 3 restricts the lateral thrust on the sand interception net 2, avoiding tilting or local collapse of the sand interception net 2.

[0048] The main frame 1 is detachably provided with at least one layer of filter net 4 contacting the sand interception net 2 on the inner side of the sand interception net 2, that is, after the water flow passes through the sand interception net 2, it enters the filter net 4 area to intercept fine particulate matter, increasing the sewage interception capacity and reducing the blockage frequency of the water conveyance pipeline. At the same time, the mesh number range of the filter net 4 is 80-120 mesh.

[0049] Specifically, the filter net 4 is closely attached to the inner side of the sand interception net 2 to ensure that the water flow passes through the sand interception net 2 and the filter net 4 in sequence to form a layered filtration.

[0050] Furthermore, the number of filter screens 4 can be set according to the actual situation. In this embodiment, the number of filter screens 4 is 2-3 layers, and the dirt interception capacity is increased by stacking the filter screens 4. At the same time, the mesh size of each layer of filter screens 4 can be gradually reduced to form gradient filtration.

[0051] During implementation, filter screen 4 intercepts fine particles (such as silt and suspended solids) that the sand-blocking screen 2 fails to filter through its high mesh size, preventing them from entering the water supply pipeline. Moreover, the layered filtration design of the sand-blocking screen 2 and filter screen 4 disperses the interception pressure and extends the service life of a single-layer filter screen.

[0052] In practice, filter screen 4 is made of corrosion-resistant, high-strength metal mesh (such as stainless steel) or synthetic fiber mesh.

[0053] Furthermore, the main frame 1 is provided with multiple limiting screws 6 around its circumference that cooperate with the filter screen 4 to fix the position of the filter screen 4, ensuring that the filter screen 4 and the sand-blocking net 2 fit tightly together and prevent sand leakage through gaps.

[0054] Specifically, the limiting screw 6 is connected to the main frame 1 through the threaded hole. After being screwed in, its spiral section contacts the filter screen 4 to form a rigid fixation, thereby realizing the fixed connection between the filter screen 4 and the main frame 1.

[0055] During implementation, the setting of the limiting screw 6 ensures that there is no gap between the filter screen 4 and the sand trap 2, preventing unblocked particles from entering the water supply pipe through the gap. Furthermore, the tight fit between the filter screen 4 and the sand trap 2 reduces turbulence or eddies in the water flow between the filter screen 4 and the sand trap 2, thereby reducing water flow resistance and improving interception efficiency.

[0056] Multiple support rods 5 are provided on the outer side of the main frame 1. Specifically, the support rods 5 are connected to the main frame 1 by welding to form a rigid support system. In this embodiment, there are 3 support rods 5, and the connection points with the main frame 1 are located at the 180° equidistant points of the lower circumference of the main frame 1.

[0057] In practice, the support rods 5 located on both sides of the main frame 1 are installed at an angle of 45° to 60° with the axis of the main frame 1. This can decompose the impact of water flow or external lateral force into a component force along the direction of the support rod 5 and transmit it to the foundation, thereby reducing the risk of lateral displacement of the device.

[0058] Meanwhile, the inclined support rod 5 and the main frame 1 form a triangular support system, which significantly enhances the device's anti-overturning ability.

[0059] The support rod 5 located at the bottom of the main frame 1 is installed vertically to provide vertical support and prevent the device from sinking or detaching from the foundation.

[0060] The support rods 5, which are vertically installed at the bottom of the main frame 1, directly transmit the weight of the device and the impact force of the water flow to the ground in the vertical direction, preventing the device from sinking or detaching from the foundation due to excessive load.

[0061] In scenarios with high groundwater levels or strong water flow impact, the vertically installed support rod 5 can provide additional vertical anchoring force to prevent the device from floating due to buoyancy.

[0062] In practical implementation, the inclined support rod 5 bears the lateral force, and the vertical support rod 5 bears the vertical force. The two work together to form a multi-directional force system, which improves the overall stability and adaptability of the device.

[0063] In this embodiment, the support rod 5 is made of a frame tube with a diameter of 48mm, which provides sufficient strength and rigidity to effectively support the weight of the device and resist impacts from water flow and external sources.

[0064] In specific implementation of this utility model:

[0065] Water carrying silt, floating debris, and other impurities enters the device from the inlet of the water supply pipe. It first enters the area of ​​the sand-blocking net 2, which is welded to the end of the main frame 1. The sand-blocking net 2 has a hole diameter of 5-10mm and intercepts large particles of silt (such as gravel, branches, etc.) and floating debris to prevent them from entering the interior of the water supply pipe.

[0066] The water that has passed through the sand trap 2 enters the filter area 4. The filter 4 is close to the inside of the sand trap 2 and uses a high mesh (80-120 mesh) metal mesh to intercept fine particles (such as silt and suspended solids) in layers.

[0067] After filtration, the water flows into the water supply pipe and forms a counterweight zone at the bottom of the pipe, which counteracts buoyancy and enhances the overall stability together with the weight of the device itself. At the same time, it works in conjunction with the anchoring force of the support rod 5 to prevent the device from floating due to buoyancy, ensuring long-term stable operation.

[0068] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
