AI Technical Summary
The existing water conservancy irrigation canals are not easy to adjust, which causes water accumulation inside the canal to rise, and the middle of the lap bridge is easily submerged, affecting pedestrian use.
A overlapping bridge for water conservancy irrigation canal was designed, and a support mechanism was used, including a float ball and a bracket. As the water level inside the canal rises, the float ball pushes the bracket up, slowly lifting the middle of the overlapping bridge to avoid flooding.
It effectively avoids the flooding problem in the middle of the overlapping bridge caused by the increase in the water level inside the canal, ensures that pedestrians can use the overlapping bridge safely, and at the same time limit the bracket through the limit ring to prevent the overlapping bridge from tilting.

Technical Field
[0001] The utility model relates to the technical field of water conservancy and irrigation, in particular to a bridge for water conservancy and irrigation canals. Background Art
[0002] At present, with the continuous development of agriculture, water conservancy irrigation canals have been widely used, and bridges for water conservancy irrigation canals are an important part of them. There are many types of bridges for water conservancy irrigation canals on the market today, which can basically meet people's needs.
[0003] Among them, in order to facilitate farmers to cross the two sides of the canal to irrigate the crops on both sides of the canal, a bridge will be laid on the canal to facilitate farmers to walk.
[0004] Most of the common lap bridges on the market are built by building wooden bridges or concrete bridges, but such lap bridges are not easy to adjust, resulting in the accumulation of water inside the canal, which can easily submerge the middle part of the lap bridge. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content
[0005] The utility model aims to provide a bridge for water conservancy irrigation canals, which solves the problems raised in the background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bridge for a water conservancy irrigation canal, comprising a canal, bridge piers are fixedly installed on both sides of the top of the canal, mounting frames are fixedly installed inside two groups of the bridge piers, a bridge is fixedly installed between the two groups of the mounting frames, and a supporting mechanism is installed on the bottom side of the middle part of the bridge;
[0007] The support mechanism includes brackets fixedly installed on both sides of the bottom of the lap bridge, mounting plates fixedly installed at the bottom of the two groups of brackets, and floating balls fixedly installed inside the mounting plates. The mounting plates are fixedly installed with the floating balls via bolts.
[0008] As an optional solution of the technical solution of the present application, mounting holes are provided on both sides of the interior of the water channel, and positioning pins are fixedly installed inside the two groups of mounting holes to fix the positioning pins.
[0009] As an optional solution of the technical solution of the present application, limiting rings are fixedly installed on the tops of the two groups of positioning pins, and the two groups of limiting rings are movably connected to the two groups of brackets respectively, so as to limit the brackets.
[0010] As an optional solution of the technical solution of the present application, protective rubber pads are fixedly installed on the outer walls of the two groups of floats to increase the service life of the floats.
[0011] As an optional solution to the technical solution of the present application, a protective rope is fixedly installed between the tops of the two groups of piers, and multiple groups of equidistantly distributed guardrails are fixedly installed on the protective rope. The other ends of the multiple groups of guardrails are fixedly installed on the top of the lap bridge, so as to protect pedestrians on the lap bridge.
[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0013] 1. The technical solution of the present application is that when the accumulated water in the canal continues to rise, with the help of the float in the supporting mechanism, as the water level in the canal continues to rise, the float can be lifted up and the bracket on the top of the float can be pushed up to slowly lift up the middle part of the bridge, so as to prevent the water level in the canal from rising continuously and flooding the middle part of the bridge, making it impossible for pedestrians to use the bridge.
[0014] 2. The technical solution of the present application has limit rings fixedly installed on the top of two groups of positioning pins, and the two groups of limit rings are movably connected to the two groups of brackets respectively. When the accumulated water inside the canal is constantly rising and flowing, the limit rings are used to support the brackets, which can effectively limit the brackets and ensure that the float at the bottom of the bracket can only float up, thereby preventing the accumulated water inside the canal from flowing and causing the float and the bracket to deviate and pull the lap bridge to tilt, thereby increasing the danger of using the lap bridge.

[0019] See also Figure 1-2 The utility model provides a technical solution: a bridge for a water conservancy irrigation canal, comprising a canal 1, bridge piers 11 are fixedly installed on both sides of the top of the canal 1, mounting frames 12 are fixedly installed inside two groups of bridge piers 11, a bridge 13 is fixedly installed between the two groups of mounting frames 12, and a supporting mechanism is installed on the bottom side of the middle part of the bridge 13;
[0020] The supporting mechanism includes brackets 23 fixedly installed on both sides of the bottom of the lap bridge 13, mounting plates 25 fixedly installed at the bottom of the two groups of brackets 23, and floats 24 fixedly installed inside the mounting plates 25. The mounting plates 25 are fixedly installed with the floats 24 by bolts inside. Protective rubber pads are fixedly installed on the outer walls of the two groups of floats 24 to increase the service life of the floats 24.
[0021] In this technical solution, when the accumulated water inside the canal 1 continues to rise, in conjunction with the float 24 in the supporting mechanism, as the water level inside the canal 1 continues to rise, the float 24 can be lifted up and the bracket 23 on the top of the float 24 can be pushed up to slowly lift the middle part of the lap bridge 13, thereby preventing the water level inside the canal 1 from continuing to rise and flooding the middle part of the lap bridge 13, making it impossible for pedestrians to use the lap bridge 13.
[0022] In some technical solutions, limiting rings 22 are fixedly installed on the tops of the two groups of positioning pins 21, and the two groups of limiting rings 22 are movably connected to the two groups of brackets 23 respectively, so as to limit the brackets 23.
[0023] In this technical solution, when the accumulated water inside the water channel 1 is constantly rising and flowing, the support 23 is supported by the limiting ring 22, which can effectively limit the support 23 and ensure that the float 24 at the bottom of the support 23 can only float up, thereby preventing the accumulated water inside the water channel 1 from flowing and causing the float 24 and the support 23 to deviate and pull the lap bridge 13 to tilt, thereby increasing the danger of using the lap bridge 13.
[0024] In some technical solutions, mounting holes 2 are provided on both sides of the water channel 1 , and positioning pins 21 are fixedly installed inside the two groups of mounting holes 2 , so that the positioning pins 21 can be fixed.
[0025] In this technical solution, the positioning pin 21 is firmly fixed inside the mounting hole 2 , which can ensure that the positioning pin 21 is firmly fixed inside the water channel 1 .
[0026] In some technical solutions, a protective rope 3 is fixedly installed between the tops of the two groups of bridge piers 11, and multiple groups of equidistantly distributed guardrails 31 are fixedly installed on the protective rope 3. The other ends of the multiple groups of guardrails 31 are fixedly installed on the top of the lap bridge 13, so as to protect pedestrians on the lap bridge 13.
[0027] In this technical solution, when the operator moves on the bridge 13 , the guardrail 31 installed in conjunction with the protective rope 3 can protect pedestrians on the bridge 13 .
[0028] When a bridge for a water conservancy irrigation canal is used, it should be noted that the utility model is a bridge for a water conservancy irrigation canal, and each component is a universal standard part or a component known to technical personnel in this field, and its structure and principle can be known to technical personnel through technical manuals or through conventional experimental methods.
[0029] When in use, the bridge piers 11 are first fixedly installed on both sides of the water channel 1, and the bridge 13 is installed between the fixedly installed bridge piers 11, so that pedestrians can cross the water channel 1 easily. At the same time, when the accumulated water in the water channel 1 continues to rise, the floating ball 24 in the supporting mechanism can be used to lift up the floating ball 24 as the water level in the water channel 1 continues to rise, and the bracket 23 on the top of the floating ball 24 can be pushed up to slowly lift up the middle part of the bridge 13, so as to prevent the water level in the water channel 1 from constantly rising and flooding the middle part of the bridge 13, so that pedestrians cannot cross the bridge 13. The bracket 23 can be used for water channel 1, and the limiting rings 22 are fixedly installed on the tops of the two groups of positioning pins 21, and the two groups of limiting rings 22 are movably connected with the two groups of brackets 23 respectively. When the accumulated water in the water channel 1 is constantly rising and flowing, the limiting rings 22 are used to support the bracket 23, which can effectively limit the bracket 23 and ensure that the floating ball 24 at the bottom of the bracket 23 can only rise and float, thereby preventing the accumulated water in the water channel 1 from flowing and causing the floating ball 24 and the bracket 23 to deviate and pull the lap bridge 13 to tilt, thereby increasing the danger of using the lap bridge 13.
