Description

Technical Field

[0001] This utility model relates to the field of cable trench facilities technology, and in particular to a prefabricated cable trench water-crossing bridge with anti-water accumulation function. Background Technology

[0002] In power engineering, cable trenches are crucial facilities for laying and protecting cables. Precast cable trench water-crossing bridges, as an important component of cable trenches, serve to facilitate the passage of personnel and vehicles and ensure a dry environment inside the trench. However, existing precast cable trench water-crossing bridges are prone to water accumulation on their surfaces during use. This water accumulation not only inconveniences pedestrians and vehicles but can also seep into the cable trench through gaps, leading to water accumulation inside the trench, affecting the normal operation of cables, and potentially even causing safety accidents.

[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: existing prefabricated cable trench water-crossing bridge plates are prone to water accumulation on the surface of the bridge plate during use. Water accumulation not only causes inconvenience to pedestrians and vehicles, but may also seep into the cable trench through gaps, causing water accumulation inside the cable trench, affecting the normal operation of the cable, and may even cause safety accidents; therefore, in order to address the above problems, a prefabricated cable trench water-crossing bridge plate with anti-water accumulation is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing prefabricated cable trench water-crossing bridge plates are prone to water accumulation on their surface during use. This water accumulation not only causes inconvenience to pedestrians and vehicles, but may also seep into the cable trench through gaps, leading to water accumulation inside the cable trench, affecting the normal operation of the cable, and even potentially causing safety accidents. Therefore, this utility model proposes a prefabricated cable trench water-crossing bridge plate with anti-water accumulation function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a prefabricated cable trench water-crossing bridge with anti-water accumulation, comprising a bridge body, the upper surface of the bridge body being provided with a guide slope inclined to both sides, the guide slope having an angle of 4-6 degrees with the horizontal plane, two water collection grooves being opened on the surface of the bridge body, and a number of drainage holes being opened on the inner wall of the water collection grooves, the number of drainage holes being opened through the bridge body.

[0006] The aforementioned components achieve the following effects: the guide slope on the upper surface of the bridge plate body can guide rainwater to flow to both sides, preventing water from accumulating on the surface; the water collection troughs on both sides can collect the guided rainwater; and the drainage holes on the inner wall of the water collection troughs penetrate the bridge plate body, allowing the collected rainwater to be quickly discharged to the outside of the bridge plate, thereby effectively preventing water accumulation on the surface of the bridge plate, ensuring a dry environment for the equipment in the cable trench, reducing equipment failures caused by water accumulation, and improving the practicality of the device.

[0007] Preferably, the bridge deck body is fixedly connected to two water baffles, and the outer side of the water baffles is provided with anti-slip texture.

[0008] The effects achieved by the above components are as follows: the water baffles on both sides of the bridge deck can prevent water from overflowing into non-drainage areas, and together with the guide slope, they form a directional drainage path to prevent rainwater from overflowing into the cable trench or surrounding areas. The anti-slip texture on the outside of the water baffle can increase the surface friction and improve the stability of the bridge deck during installation.

[0009] Preferably, the inner wall of the water collection tank is fixedly connected to a mounting bracket, the inner wall of the mounting bracket is slidably connected to a filter plate, the surface of the filter plate is fixedly connected to two sliding chambers, the inner wall of the water collection tank is provided with two fixed grooves, the inner cavity of the sliding chamber is slidably connected to a sliding rod, the size of the sliding rod is adapted to the size of the fixed groove, the arc surface of the sliding chamber is provided with a sliding groove, the arc surface of the sliding rod is fixedly connected to an operating plate, and the operating plate is slidably connected to the inner wall of the sliding groove of the sliding chamber.

[0010] The effects achieved by the above components are as follows: by setting up a filter plate, the filter plate can intercept impurities such as leaves and mud in rainwater, prevent the drainage holes from being blocked, and ensure smooth drainage. The cooperation between the sliding rod, the fixed groove, and the operating plate allows the filter plate to be quickly disassembled and assembled without tools, making it convenient to clean up debris, reducing maintenance time and labor costs, while ensuring that the filter plate is installed firmly, thus improving the practicality of the device.

[0011] Preferably, one end of the sliding rod is fixedly connected to a spring, and the other end of the spring is fixedly connected to the inner wall of the sliding chamber.

[0012] The effect achieved by the above components is that by setting a spring, the spring force makes the sliding rod tightly locked into the fixing groove, ensuring that the filter plate is stable and does not loosen, and can maintain a reliable working state even under the impact of water flow, thus improving the practicality of the device.

[0013] Preferably, two connecting blocks are fixedly connected to the side wall of the bridge plate body, and two connecting grooves are opened on the side of the bridge plate body away from the connecting blocks. The connecting blocks are trapezoidal blocks, and the connecting grooves are trapezoidal grooves that are adapted to the connecting blocks.

[0014] The effects achieved by the above components are as follows: the connection stability and installation convenience between the bridge plate bodies are enhanced by the cooperation of the connecting block and the connecting groove. The connecting block and the connecting groove adopt a suitable trapezoidal structure, which can be quickly and accurately aligned by the inclined surface during installation, effectively improving the installation efficiency. At the same time, the wedge-like action of the trapezoid makes it difficult for the bridge plates to move laterally or longitudinally after splicing, thus improving the practicality of the device.

[0015] Preferably, the surface of the connecting block is covered with a waterproof sealing strip.

[0016] The effects achieved by the above components are as follows: the waterproof sealing strip on the surface of the connecting block can effectively fill the gaps in the splicing of the bridge plate body, achieving the effects of waterproof sealing and shock absorption. The waterproof sealing strip can tightly fit the connecting block and the connecting groove, preventing rainwater and sewage from seeping into the bridge plate joints and avoiding water flow into the cable trench to corrode cables and equipment. At the same time, the elastic properties of the strip can buffer the vibration and friction caused by external forces at the splicing of the bridge plate body, reduce component wear, and extend the service life of the bridge plate body.

[0017] Preferably, the bottom surface of the bridge plate body is fixedly connected with reinforcing ribs, which are distributed in a mesh pattern.

[0018] The effects achieved by the above components are as follows: the mesh structure of the reinforcing ribs evenly distributes the force on the bottom surface of the bridge deck body, effectively enhancing the overall compressive and deformation resistance of the bridge deck body. Even when subjected to heavy vehicle crushing or long-term water flow impact, the structure can remain stable. At the same time, the reinforcing ribs can also improve the bending strength of the bridge deck body, prevent the middle of the bridge deck body from denting or breaking due to force, and improve the practicality of the device.

[0019] In this invention, the guide slope on the upper surface of the bridge plate body can guide rainwater to flow to both sides, preventing water from accumulating on the surface. The water collection troughs on both sides can collect the guided rainwater, and the drainage holes on the inner wall of the water collection troughs penetrate the bridge plate body, so that the collected rainwater can be quickly discharged to the outside of the bridge plate. This effectively prevents water accumulation on the surface of the bridge plate, ensures a dry environment for the equipment in the cable trench, reduces equipment failure caused by water accumulation, and improves the practicality of the device.

[0027] Reference Figure 1-6As shown, this utility model provides a technical solution: a prefabricated cable trench water-crossing bridge with anti-water accumulation function, including a bridge body 1. The upper surface of the bridge body 1 is provided with a guide slope 2 inclined to both sides, the angle between the guide slope 2 and the horizontal plane is 4-6 degrees. Two water collection grooves 3 are opened on the surface of the bridge body 1. The inner wall of the water collection grooves 3 is provided with a plurality of drainage holes 4, which are opened through the bridge body 1. The guide slope 2 on the upper surface of the bridge body 1 can guide rainwater to flow to both sides, avoiding water accumulation on the surface. The water collection grooves 3 on both sides can collect the guided rainwater. The drainage holes 4 on the inner wall of the water collection grooves 3 are opened through the bridge body 1, which can quickly discharge the collected rainwater to the outside of the bridge, thereby effectively preventing water accumulation on the surface of the bridge and protecting the cable trench. The dry environment inside the equipment reduces equipment malfunctions caused by water accumulation, improving the practicality of the device. Two water-blocking plates 5 are fixedly connected to the bridge plate body 1. The outer side of the water-blocking plates 5 has anti-slip textures. The water-blocking plates 5 on both sides of the bridge plate body 1 can prevent water from overflowing into non-drainage areas, forming a directional drainage path with the guide slope 2, preventing rainwater from overflowing into the cable trench or surrounding areas. The anti-slip textures on the outer side of the water-blocking plates 5 increase surface friction, improving the stability of the bridge plate body 1 during installation. A mounting bracket 6 is fixedly connected to the inner wall of the water collection tank 3. A filter plate 7 is slidably connected to the inner wall of the mounting bracket 6. Two sliding chambers 8 are fixedly connected to the surface of the filter plate 7. Two fixed grooves are opened on the inner wall of the water collection tank 3. A sliding rod 9 is slidably connected to the inner cavity of the sliding chamber 8. The dimensions of the moving rod 9 are matched with the dimensions of the fixed groove. A sliding groove is provided on the arc surface of the sliding chamber 8. An operating plate 10 is fixedly connected to the arc surface of the moving rod 9. The operating plate 10 is slidably connected to the inner wall of the sliding groove in the sliding chamber 8. By setting a filter plate 7, the filter plate 7 can intercept impurities such as leaves and mud in rainwater, preventing blockage of the drainage hole 4 and ensuring smooth drainage. The cooperation between the moving rod 9, the fixed groove, and the operating plate 10 allows the filter plate 7 to be quickly disassembled and assembled without tools, facilitating cleaning and reducing maintenance time and labor costs. It also ensures the filter plate 7 is securely installed, improving the practicality of the device. A spring 11 is fixedly connected to one end of the moving rod 9, and the other end of the spring 11 is fixedly connected to the inner wall of the sliding chamber 8. By setting the spring 11, the elastic force of the spring 11 causes the sliding rod 9 to slide... Rod 9 is tightly inserted into the fixing groove, ensuring that the filter plate 7 is stable and does not loosen, maintaining a reliable working state even under water flow impact, thus improving the practicality of the device. Two connecting blocks 13 are fixedly connected to the side wall of the bridge plate body 1. Two connecting grooves 12 are opened on the side of the bridge plate body 1 away from the connecting blocks 13. The connecting blocks 13 are trapezoidal blocks, and the connecting grooves 12 are trapezoidal grooves adapted to the connecting blocks 13. Through the cooperation of the connecting blocks 13 and the connecting grooves 12, the connection stability and installation convenience between the bridge plate bodies 1 are enhanced. The connecting blocks 13 and the connecting grooves 12 adopt a compatible trapezoidal structure, which can be guided by the inclined surface to quickly and accurately align during installation, effectively improving installation efficiency. At the same time, the wedge-like action of the trapezoid makes it difficult for the bridge plates to undergo lateral or longitudinal displacement after splicing, improving the practicality of the device.The surface of the connecting block 13 is covered with a waterproof sealing strip 14. The waterproof sealing strip 14 effectively fills the gaps in the splicing joints of the bridge plate body 1, achieving waterproof sealing and shock absorption. The waterproof sealing strip 14 can tightly fit the connecting block 13 and the connecting groove 12, preventing rainwater and sewage from seeping into the bridge plate joints and avoiding water flow into the cable trench to corrode cables and equipment. At the same time, the elastic properties of the strip can buffer the vibration and friction caused by external forces at the splicing joints of the bridge plate body 1, reduce component wear, and extend the service life of the bridge plate body 1. The bottom surface of the bridge plate body 1 is fixedly connected with reinforcing ribs 15. The reinforcing ribs 15 are distributed in a mesh pattern. The mesh structure of the reinforcing ribs 15 evenly distributes the force on the bottom surface of the bridge plate body 1, effectively enhancing the overall compressive and deformation resistance of the bridge plate body 1. Even when subjected to heavy vehicle crushing or long-term water flow impact, the structure can remain stable. At the same time, the reinforcing ribs 15 can also improve the bending strength of the bridge plate body 1, preventing the middle of the bridge plate body 1 from denting or breaking due to force, thus improving the practicality of the device. ,

[0028] Working principle: The guide slope 2 on the bridge plate body 1, inclined at an angle of 4-6 degrees, quickly directs rainwater to the water collection tanks 3 on both sides. The drainage holes 4 on the inner wall of the water collection tanks 3 penetrate the bridge plate body 1, allowing rainwater to drain quickly and preventing water accumulation on the surface of the bridge plate body 1, thus creating a dry environment for the cable trench equipment. The water baffle 5, in conjunction with the guide slope 2, forms a directional drainage path to prevent water overflow. Its outer anti-slip texture increases friction, ensuring the passage of personnel and equipment and the stability of the bridge plate body 1 during installation. The filter plate 7 inside the water collection tank 3 can be quickly disassembled and assembled without tools with the cooperation of the sliding rod 9, the operating plate 10, and the spring 11. The filter plate 7 intercepts impurities such as leaves and mud in the rainwater, preventing the drainage holes 4 from becoming clogged. The spring 11 causes the sliding rod 9 to engage in the fixing groove, ensuring the filter plate 7 is stable and guaranteeing the long-term smooth operation of the drainage system. When the bridge plate body 1 is spliced, the trapezoidal connecting block 13 and the connecting groove 12 are precisely aligned through the inclined surface, making installation convenient. Its wedge structure effectively prevents the bridge plate body 1 from shifting laterally and longitudinally. The waterproof sealing strip 14 on the surface of the connecting block 13 fills the gaps, providing both waterproofing and shock absorption, preventing corrosion and wear of equipment and components in the cable trench. The mesh reinforcing ribs 15 on the bottom surface of the bridge plate body 1 evenly distribute the force, enhancing the bridge plate body 1's resistance to pressure, deformation, and bending. This ensures that the bridge plate body 1 remains structurally stable under complex working conditions such as heavy-load crushing and water flow impact, extending its service life and comprehensively guaranteeing the safe and efficient operation of the cable trench water-crossing bridge plate body 1.
