Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower engineering technology, specifically to a safety protection device for water conservancy and hydropower engineering. Background Technology

[0002] During the construction and operation of water conservancy and hydropower projects, various water conveyance and diversion pipelines serve as core infrastructure, widely distributed in open-air operation areas, tunnel entrances and exits, and around key projects. These pipelines are exposed to complex environments for extended periods, not only bearing loads such as water flow pressure and geological settlement, but also facing threats from falling objects generated during construction or surrounding operations—for example, steel pipes and fasteners falling from scaffolding above, gravel rolling down during tunnel excavation, or tools and parts accidentally falling during maintenance and repair, all of which can impact the pipelines.

[0003] Currently, protective measures for pipelines in water conservancy and hydropower projects mainly focus on corrosion prevention, settlement resistance, and leakage prevention, with a significant lack of specific protective measures against falling objects from heights. Existing technologies sometimes involve laying simple plastic sheeting or tarpaulins over the pipelines, but these materials have extremely low strength and offer almost no resistance to falling metal components, stones, or other hard objects. They can only block a small amount of dust or rainwater, failing to provide effective protection. A few projects construct steel protective sheds; however, these are bulky, difficult to install and dismantle, and unsuitable for pipes of different diameters. Once fixed, they cannot be flexibly adjusted according to the pipeline's laying path. Especially in mountainous or complex terrain areas, the transportation and installation costs of steel protective sheds are extremely high, and they also hinder daily pipeline inspection and maintenance.

[0004] More importantly, none of the existing protection methods mentioned above have a specific design for catching and cushioning falling objects. When objects falling from a height impact pipelines, they can cause minor damage such as scratches on the outer wall and damage to the anti-corrosion layer, shortening the pipeline's service life. In severe cases, they can cause pipeline cracking, leakage, or even pipeline breakage. This can not only lead to the shutdown of water conservancy and hydropower projects and cause huge economic losses, but may also cause secondary disasters such as soil erosion and foundation collapse due to water leakage, seriously threatening the safety of the project and the surrounding environment. Therefore, there is an urgent need for a device that is highly adaptable, has reliable protective effects, and is easy to operate to solve the technical problem of falling objects from heights easily damaging pipelines and causing safety accidents in existing technologies. Utility Model Content

[0005] To overcome the above-mentioned defects, embodiments of this utility model provide a safety protection device for water conservancy and hydropower projects, which solves the technical problem in related technologies that falling objects from heights can easily damage pipelines and cause safety accidents.

[0006] According to one aspect, at least one embodiment of the present invention provides a safety protection device for water conservancy and hydropower projects, used for pipeline protection, comprising:

[0007] A support, which is mounted on the outer peripheral wall of the pipe;

[0008] A protective net is detachably installed above the support and extends along the axial direction of the pipe. The protective net is used to catch objects falling from above the pipe.

[0009] For example, in at least one embodiment of the present invention, a safety protection device for water conservancy and hydropower projects further includes:

[0010] The support rods are of several kinds, and all of the support rods are set on the bracket. The end of the support rod away from the bracket is detachably connected to the corner of the protective net.

[0011] There are two retaining rings, one of which is sleeved on the end of the support rod near the protective net, and the other retaining ring is fixedly sleeved on the end of the support rod near the bracket;

[0012] An elastic element is disposed between the two retaining rings, and both ends of the elastic element abut against the two retaining rings respectively.

[0013] For example, in a safety protection device for water conservancy and hydropower projects provided in at least one embodiment of the present invention, the bracket has a plurality of brackets, which are arranged at intervals along the axial direction of the pipeline, and each bracket is provided with at least two support rods.

[0014] For example, in a safety protection device for water conservancy and hydropower projects provided in at least one embodiment of this utility model, the bracket is inverted U-shaped, and the inner wall of the bracket abuts against the outer wall of the pipe.

[0015] For example, in a safety protection device for water conservancy and hydropower projects provided in at least one embodiment of this utility model, an installation ring is provided on the protective net, and the installation ring is sleeved on the support rod and abuts against the retaining ring at the top of the support rod.

[0016] For example, in a safety protection device for water conservancy and hydropower projects provided in at least one embodiment of this utility model, the outer peripheral wall of the bracket is provided with a mounting frame, the mounting frame is provided with a connecting component, and the support rod is connected to the mounting frame through the connecting component. The connecting component includes:

[0017] Mounting base, the mounting base is disposed on the mounting frame, and the mounting base is swiveled with a pawl;

[0018] A rotating rod is rotatably mounted on the mounting base. A ratchet is provided on the rotating rod, and the ratchet meshes with a pawl. The ratchet and pawl cooperate to limit the inclined support rod.

[0019] A snap-fit ​​element is provided on the rotating rod, and the bottom end of the support rod is snapped into the snap-fit ​​element.

[0020] For example, in a safety protection device for water conservancy and hydropower projects provided in at least one embodiment of this utility model, the protective net is arranged at an angle to one side of the pipeline.

[0021] For example, in a safety protection device for water conservancy and hydropower projects provided in at least one embodiment of the present invention, the bottom of the bracket is provided with a positioning anchor rod, which can be inserted into the ground so that the bracket is fixedly erected on the ground.

[0022] For example, in a safety protection device for water conservancy and hydropower projects provided in at least one embodiment of this utility model, the positioning anchor rod includes:

[0023] A positioning rod is mounted on the bracket, the positioning rod can pass through the bottom of the bracket, and the positioning rod is provided with a threaded portion; the positioning rod has a tip for inserting into the ground;

[0024] A locking nut is threadedly connected to the threaded portion of the positioning rod, and the locking nut is used to adjust the distance by which the positioning rod extends beyond the bottom of the bracket.

[0025] For example, in a safety protection device for water conservancy and hydropower projects provided in at least one embodiment of this utility model, the elastic element is a spring.

[0026] The beneficial effects of this utility model are as follows:

[0027] In this invention, the device provides stable support for the protective netting via supports erected on the outer wall of the pipeline. This allows the netting to cover the area above the pipeline and extend axially along the pipeline, forming a protective barrier above the pipeline. When objects fall from a height (such as construction debris, tool parts, scaffolding components, etc.), the protective netting directly catches them, preventing direct impact on the pipeline's outer wall, protecting the integrity of the pipeline structure, reducing the risk of cracking and leakage, and ensuring the stable operation of water conveyance and diversion systems in water conservancy and hydropower projects. The protective netting and supports are detachably connected. When the pipeline requires routine inspection, maintenance, or partial repairs, the protective netting can be quickly disassembled to avoid obstructing maintenance work. After maintenance is completed, the protective netting can be easily reassembled to restore its protective function. Attached Figure Description

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0035] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0036] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

[0039] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0040] like Figures 1-4 As shown, a safety protection device for water conservancy and hydropower projects according to an embodiment of the present invention is illustrated, including a support 1 and a protective net 2. The support 1 is mounted on the outer periphery of the pipeline, and its arrangement along the pipeline's extension direction ensures stable support for the protective net 2. The protective net 2 is detachably mounted above the support 1 and extends along the pipeline's axial direction, with its coverage area corresponding to the area above the pipeline susceptible to impact from falling objects.

[0041] Support 1 is mounted on the outer wall of the pipeline, allowing it to be installed directly against the pipeline without occupying a large amount of space around it. Protective netting 2 extends axially along the pipeline, matching the protected area to the pipeline length and providing continuous axial protection. The detachable connection between protective netting 2 and support 1 provides a structural basis for the installation, disassembly, and subsequent adjustments of the device. On one hand, when the pipeline requires inspection or maintenance, protective netting 2 can be quickly disassembled, preventing the protective device from obstructing maintenance operations and ensuring their smooth progress. On the other hand, when protective netting 2 is damaged or its protective position needs adjustment, it can be disassembled and replaced or adjusted independently without disassembling the entire support 1, reducing maintenance costs and operational complexity. The combined structure of support 1 and protective net 2 forms a protective barrier above the pipeline. When objects fall from a height, protective net 2 directly catches them, using its structural strength to resist impact and prevent direct collisions with the pipeline. This protects the pipeline's outer wall and reduces the probability of scratches, cracks, and leaks caused by falling objects, ensuring the stable operation of pipeline systems in water conservancy and hydropower projects and mitigating the risk of project shutdowns or secondary disasters due to pipeline damage. Furthermore, the structural coordination between support 1 and protective net 2 allows the device to adjust the spacing of support 1 and the extension length of protective net 2 according to the pipeline's laying path, adapting to different pipeline protection needs in various laying scenarios. Compared to fixed-structure protective devices, this enhances the device's adaptability to different pipeline protection scenarios.

[0042] The workflow is as follows: In pipeline protection operations, support 1 is first erected on the outer perimeter of the pipeline to complete the positioning and fixation of support 1; then, protective net 2 is unfolded along the pipeline axis and detachably connected to support 1 above it, so that protective net 2 is in the preset protection position above the pipeline; when a falling object falls towards the pipeline, protective net 2 directly catches the falling object, preventing the falling object from contacting the pipeline, thus protecting the pipeline; when it is necessary to inspect, maintain or adjust the protected area of ​​the pipeline, protective net 2 can be removed from support 1, and after the operation is completed, protective net 2 can be reconnected to support 1 to restore the protective function.

[0043] Specifically, this device also includes support rods 3, retaining rings 4, and elastic elements 5. Several support rods 3 are provided, all of which are set on the bracket 1. The end of the support rod 3 away from the bracket 1 is detachably connected to the corner of the protective net 2. For example, the protective net 2 can be tied to the support rod 3 with ropes, or hooks can be installed at the corner of the protective net 2 to install the protective net 2 on the support rod 3, or hanging rings can be installed at the corner of the protective net 2 and the hanging rings can be put on the support rod 3. Two retaining rings 4 are provided, one is fitted on the end of the support rod 3 near the protective net 2, and the other is fixedly fitted on the end of the support rod 3 near the bracket 1. The elastic element 5 is set between the two retaining rings 4, and the two ends of the elastic element 5 abut against the two retaining rings 4 respectively.

[0044] The detachable connection of several support rods 3 to the corners of the protective net 2 not only provides multi-point support for the protective net 2 but also enhances its structural stability and facilitates its disassembly and replacement. The two retaining rings 4 serve as the mounting base for the elastic element 5. The elastic element 5, positioned between the two retaining rings 4, utilizes its elasticity to buffer the impact of falling objects. When a falling object impacts the protective net 2, the net 2 transmits the impact force to the support rods 3. The support rods 3 cause the retaining rings 4 near one end of the net 2 to slide down along the support rods 3, compressing the elastic element 5. The elastic element 5 deforms, absorbing part of the impact force, thus buffering the impact and preventing the falling object from breaking the protective net 2.

[0045] Specifically, several supports 1 are provided, spaced apart along the axial direction of the pipeline. This spacing prevents excessive stress on a single support 1, which could lead to localized pressure damage to the pipeline, and also enhances the overall stability of the device along the pipeline's axial direction. Each support 1 has at least two support rods 3, which are arranged upwards and extend obliquely upwards towards the outside of the pipeline to facilitate the opening of the protective net 2. This enhances the stability of the connection between the protective net 2 and the support 1.

[0046] Specifically, the support 1 is in the shape of an inverted U, with the inner wall of the support 1 abutting against the outer wall of the pipe, which improves the stability of the connection between the support 1 and the pipe, and uses the pipe's own structure and the ground to provide positioning for the support 1.

[0047] Furthermore, the protective net 2 is equipped with an installation ring 6, which is fitted onto the support rod 3 and abuts against the retaining ring 4 at the top of the support rod 3. By fitting the installation ring 6 onto the support rod 3, the protective net 2 and the support rod 3 can be detachably connected. Furthermore, the installation ring 6, in conjunction with the retaining ring 4, can limit the position of the protective net 2 on the support rod 3, thereby adjusting the installation position of the protective net 2 on the support rod 3. When it is necessary to disassemble the protective net 2, the installation ring 6 can be directly removed from the support rod 3. When a falling object impacts the protective net 2, the installation ring 6 transmits the impact force to the retaining ring 4 at the top of the support rod 3. The retaining ring 4 slides downwards, compressing the elastic element 5, thus cushioning the impact of the protective net 2.

[0048] Furthermore, a mounting frame 7 is provided on the outer peripheral wall of the bracket 1, and a connecting component 8 is provided on the mounting frame 7. The connecting component 8 includes a mounting base 81, a rotating rod 82, a ratchet 83, a pawl 84, and a locking member 85. The mounting base 81 is mounted on the mounting frame 7, and the pawl 84 is oscillatingly mounted on the mounting base 81. The rotating rod 82 is rotatably mounted on the mounting base 81, and the ratchet 83 is provided on the rotating rod 82. The ratchet 83 and the pawl 84 mesh with each other. It should be noted that the ratchet 83 and the pawl 84 are existing technologies and will not be described in detail here. The locking member 85 is provided on the rotating rod 82. The locking member 85 is a clamp or a retaining ring. The bottom of the support rod 3 is locked with the locking member 85. The lower end of the support rod 3 is provided with a boss. The lower end face of the boss can abut against the upper end face of the locking member 85, thereby restricting the downward sliding of the support rod 3.

[0049] In this example, as Figure 1 As shown, all support rods 3 are tilted to the right, causing the protective net 2 to tilt to the right as well. The combination of the mounting bracket 7 and the connecting component 8, in conjunction with the support rods 3, enables the adjustment and limiting of the tilt angle of the support rods 3. The mounting base 81 is fixed to the mounting base 81 with bolts, ensuring that the connecting component 8 does not shift under force. The rotation of the rotating rod 82 and the mounting base 81 allows the tilt angle of the support rods 3 to be adjusted according to protection requirements, adapting to protection scenarios of different heights and ranges. Compared with a support rod 3 with a fixed angle, this improves the adaptability of the device. The engagement and limiting of the ratchet 83 and the pawl 84 can fix the angle of the support rods 3 after they are adjusted to a suitable angle, preventing the angle of the support rods 3 from changing when receiving the impact of falling objects, and ensuring the stability of the support rods 3 in supporting the protective net 2. The snap-fit ​​component 85 enables the snap-fit ​​between the support rods 3 and the rotating rod 82, facilitating the quick installation, disassembly, and replacement of the support rods 3, and reducing maintenance costs. Furthermore, this structure makes the installation and angle adjustment of the support rod 3 more flexible. The tilt angle of the support rod 3 can be changed according to the actual falling direction of the falling object, further improving the bearing efficiency of the protective net 2 and enhancing the protective effect of the device.

[0050] Specifically, the protective net 2 is tilted towards one side of the pipe, which allows the falling objects to slide down to one side of the pipe under the action of gravity, preventing the falling objects from accumulating on the protective net 2 and preventing the protective net 2 from being damaged due to excessive stress caused by long-term accumulation of falling objects.

[0051] Falling objects can automatically slide down the inclined protective netting 2 under the influence of gravity, preventing them from accumulating on it and thus avoiding deformation or damage due to excessive weight, thereby extending the service life of the netting 2. This also reduces the frequency of manual cleaning of the netting 2, lowering maintenance costs. Furthermore, the fact that falling objects slide towards one side of the pipeline prevents them from falling from the edge of the netting 2 into other areas around the pipeline, reducing potential threats to surrounding facilities or personnel. Compared to a horizontally installed protective netting 2, this further enhances the safety and practicality of the device.

[0052] Specifically, the bottom of the support frame 1 is equipped with a positioning anchor rod 9, which can be inserted into the ground. The anchor rod 9's insertion into the ground enhances the overall stability of the support frame 1, preventing it from tipping over or shifting under load. The connection between the positioning anchor rod 9 and the bottom of the support frame 1 provides both support from the pipe's outer wall and fixation to the ground, improving overall structural stability. Furthermore, the positioning anchor rod 9 allows the support frame 1 to be stably erected even in slightly undulating terrain, expanding the applicability of the device and improving its reliability in complex environments.

[0053] Specifically, the positioning anchor rod 9 includes a positioning rod 91 with a tip 92 and a locking nut 93. The positioning rod 91 has a threaded portion. The positioning rod 91 can be inserted into the ground after passing through the mounting hole on the bottom of the bracket 1. The tip 92 is located at the end of the positioning rod 91 that is inserted into the ground, reducing the difficulty of inserting the positioning rod 91 into the ground. At least two locking nuts 93 are provided on the positioning rod 91. The two locking nuts 93 are located at the top and bottom of the bottom horizontal plate of the bracket 1, respectively. The two locking nuts 93 can lock the positioning rod 91 onto the bottom horizontal plate of the bracket 1. The engagement between the locking nuts 93 and the threaded portion of the positioning rod 91 allows the length of the positioning rod 91 extending beyond the bottom of the bracket 1 to be fixed by tightening the locking nuts 93, thereby adjusting the insertion depth of the positioning rod 91 into the ground. When it is necessary to adjust the insertion depth of the positioning rod 91, loosen the locking nuts 93, adjust the extension length of the positioning rod 91, and then tighten the locking nuts 93 to fix it.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
