[0034] The utility model is further described below in conjunction with the accompanying drawings:

[0035] like Figure 1-Figure 10 As shown, a sewage intercepting device for water conservancy projects includes a pull rope 1, a plurality of intercepting mechanisms 2 are connected in series on the outside of the pull rope 1, and a locking mechanism 3 is provided in the middle of the intercepting mechanism 2.

[0036] In this embodiment, the interception mechanism 2 includes two opposing floating cylinders 21, a plurality of fence rods 22 are arranged between the two floating cylinders 21, and the two floating cylinders 21 and the plurality of fence rods 22 form a cage structure, the end of the fence rod 22 close to the floating cylinder 21 is a swing end, and the end of the fence rod 22 away from the floating cylinder 21 is a contact end, and the sides of the two floating cylinders 21 close to each other are both provided with a turnover groove 24 and a spring fixing groove 25, and the spring fixing groove 25 is located on the side where the turnover groove 24 faces the floating cylinder 2. 1, a main shaft is fixed inside the turnover groove 24, and one end of the fence rod 22 extending into the turnover groove 24 is sleeved on the outside of the main shaft, a spring 23 is fixed at a position of the fence rod 22 near its swing end, and a limiting ring 26 is provided between the floating cylinders 21 and is sleeved on the contact ends of multiple fence rods 22. The two ends of the inner side of the limiting ring 26 are provided with inclined surfaces for tightening the contact ends of multiple fence rods 22. The end of the spring 23 away from the fence rod 22 is fixed on the inner side of the spring fixing groove 25, and three The support seats 262 are arranged in an annular manner, and an annular groove 261 penetrating through the three support seats 262 is provided on the outer side of the limiting ring 26. The interior of the floating cylinder 21 is a hollow structure, and a through hole for the pull rope 1 to pass through is provided at the center of the floating cylinder 21. The hollow structure of the floating cylinder 21 is used to make the whole float on the water surface, and the multiple interception mechanisms 2 strung together by the pull rope 1 are used to block the dirt on the water. Since the multiple fence rods 22 on the floating cylinder 21 are arranged in a conical structure, when the blocked dirt is large, the water As the impact force of the flow on the dirt increases, the contact end of the fence rod 22 that blocks the dirt will flip toward the inside of the limit ring 26 with the main axis of its swing end as the center. At this time, the flipped fence rod 22 will open an opening gap at the contact end and the limit ring 26, and then let the blocked dirt enter the cage structure composed of multiple fence rods 22 and two floating tubes 21. When the dirt completely enters between the multiple fence rods 22, the spring 23 pushes the fence rod 22 to flip and reset, and then completes the blocking and collection of the dirt.

[0037] In this embodiment: the locking mechanism 3 includes three supporting components, each supporting component is provided with a first gear 33, a rotating sleeve 35 is provided between the three first gears 33, and a second gear ring 34 for meshing with the three first gears 33 is fixed on the outer side of the rotating sleeve 35. Each supporting component is composed of two locking support rods 31 and a threaded sleeve 32. The two locking support rods 31 are respectively located at both sides of the threaded sleeve 32, and the end of the locking support rod 31 away from the threaded sleeve 32 is fixedly connected to the floating tube 21, and the end of the locking support rod 31 extending into the threaded sleeve 32 is provided with a thread, and the threaded sleeve 32 is fixedly connected to the first gear 33. The rotating sleeve 35 is rotatably connected in the annular groove 261 of the limiting ring 26, and the support seat 262 is provided with a thread for the threaded sleeve 32 to rotate The first gear 33 is located in the middle of the rotating hole of the support seat 262, and the rotating sleeve 35 is rotated along the annular groove 261 on the outer side of the limit ring 26 by toggling the rotating sleeve 35. The second gear ring 34 is driven by the rotating sleeve 35 to rotate the three first gears 33 meshing with it. Then the three first gears 33 respectively drive the three corresponding threaded sleeves 32 to rotate in the support seat 262, and the rotation of the threaded sleeve 32 is used to push the end of the locking support rod 31 inside it outward, and then the two floating cylinders 21 are pushed away from each other through the three groups of locking support rods 31. The floating cylinders 21 that are away from each other are used to allow the contact ends of multiple fence rods 22 to separate from the limit ring 26 to produce a certain opening gap. At this time, dirt can fall out from the gap between the contact ends of the fence rods 22 and the limit ring 26.

[0038] Working principle: When in use, first string a plurality of interception mechanisms 2 on the outside of the pull rope 1, and fix the two ends of the pull rope 1 on both sides of the river bank of the water conservancy project, and at the same time, let the plurality of interception mechanisms 2 be located at the pollution interception position of the river channel of the water conservancy project;

[0039] At this time, the dirt in the river channel of the water conservancy project will drift down with the water flow. At this time, the hollow structure of the floating tube 21 allows the whole to float on the water surface, and the multiple interception mechanisms 2 strung together by the pull rope 1 are used to block the dirt on the water. Since the multiple fence rods 22 on the floating tube 21 are arranged in a conical structure, when the blocked dirt is more, the impact force of the water flow on the dirt increases, and the resistance end of the fence rod 22 that blocks the dirt will be turned toward the inside of the limit ring 26 with the main axis of its swing end as the center. At this time, the turned fence rod 22 will open an opening gap at the resistance end and the limit ring 26, and then let the blocked dirt enter the cage structure composed of multiple fence rods 22 and two floating tubes 21. When the dirt completely enters between the multiple fence rods 22, the spring 23 pushes the fence rod 22 to turn and reset, and then the dirt is blocked and collected;

[0040] When it is necessary to clean the dirt in the interception mechanism 2, the two ends of the pull rope 1 are opened, and then one end of the pull rope 1 with the new interception mechanism 2 is fixed to the end of the pull rope 1 of the interception mechanism 2 to be cleaned by the traction device, and then the traction device drags the pull rope 1 of the interception mechanism 2 to be cleaned to move it to the river channel, and then the pull rope 1 of the new interception mechanism 2 is straddled on the river channel, and then the replacement of the entire dirt interception device can be quickly completed;

[0041] The interception mechanism 2 removed from the river channel of the water conservancy project is moved to the position for collecting waste, and then the rotating sleeve 35 is turned to rotate along the annular groove 261 outside the limit ring 26, and the rotating sleeve 35 is used to drive the second gear ring 34 to rotate the three first gears 33 meshing with it, and then the three first gears 33 respectively drive the three corresponding threaded sleeves 32 to rotate in the support seat 262, and the rotation of the threaded sleeve 32 is used to push outward the end of the locking support rod 31 inside it, and then the two floating cylinders 21 are pushed away from each other through the three sets of locking support rods 31. The floating cylinder 21 allows the contact ends of the multiple fence rods 22 to separate from the limiting ring 26 to generate a certain opening gap, at which time the dirt can fall out from the gap between the contact ends of the fence rods 22 and the limiting ring 26, and then the rotating sleeve 35 is rotated in the opposite direction to make the three first gears 33 and the three threaded sleeves 32 rotate in the opposite direction through the second gear ring 34, and then the end of the locking support rod 31 is screwed back into the inside of the threaded sleeve 32, and then the contact end of the fence rod 22 is pressed against the inner side of the limiting ring 26 again, and then the whole dirt cleaning process is completed, and then the interception mechanism 2 after cleaning can be put on the outside of the pull rope 1 again;

[0042] In addition, when there is no need to intercept river sewage of the water conservancy project, the fixation of the two ends of the pull rope 1 can be untied, and the multiple interception mechanisms 2 on the outer side of the pull rope 1 can be removed.
