Description

Technical Field

[0001] The utility model relates to the technical field of drain pipes, in particular to a bridge deck drain pipe device for bridges. Background Art

[0002] During the construction of a bridge, drain pipes need to be reserved for subsequent drainage of the bridge deck. The construction quality of the drain pipes has a significant impact on the life of the bridge during long-term use.

[0003] In the prior art, patent CN216864815U discloses a bridge deck drain pipe device. When the drain end of the drain pipe body is submerged in accumulated water, the sealing plate stretches the reset assembly under the action of water pressure, and the sealing plate opens from the pipe mouth of the diversion pipe, allowing the water stored in the drain pipe body to be discharged normally, thereby not affecting the drainage of the drain pipe and avoiding water accumulation on the bridge deck.

[0004] However, in actual use, the rainwater flowing on the bridge surface will carry some dust and dirt. Since the water flow is slow, the impact force is weak, and the impurities will accumulate on the top of the filter plate, causing the pipe to be blocked, thereby affecting the discharge of water on the bridge surface. Utility Model Content

[0005] The purpose of the utility model is to provide a bridge deck drain pipe device for a bridge, so as to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A bridge deck drain pipe device for a bridge comprises a pipe body, an annular seat, a receiving ring, a built-in filter plate and a built-in dredging plate. The receiving ring, the built-in filter plate and the built-in dredging plate are sequentially distributed inside the annular seat from top to bottom. A dredging plate pushing assembly for pushing the built-in dredging plate to move upward to dredge the built-in filter plate is provided below the receiving ring.

[0008] A positioning ring is fixedly connected to the inner wall of the annular seat, a buffer reset spring is fixedly connected to the upper surface of the positioning ring, and one end of the buffer reset spring away from the positioning ring is fixedly connected to the bottom surface of the receiving ring.

[0009] The bottom surface of the built-in filter plate is provided with filter holes, and the upper surface of the built-in dredging plate is fixedly connected with a dredging rod adapted to the filter holes.

[0010] A further improvement of the technical solution of the present utility model is that the dredging plate pushing assembly includes a first connecting rod whose top end is rotatably connected to the bottom of the built-in dredging plate, the bottom end of the first connecting rod is rotatably connected to a sliding ring, one end of the sliding ring is rotatably connected to a second connecting rod, the inner wall of the sliding ring is movably sleeved with a guide slide rod, and one end of the guide slide rod is fixedly connected to the inner wall of the annular seat.

[0011] A further improvement of the technical solution of the present utility model is that the bottom surface of the built-in filter plate is fixedly connected to the inner wall of the annular seat through a filter plate positioning rod, and the connecting end of the filter plate positioning rod and the inner wall of the annular seat is located below the positioning ring.

[0012] A further improvement of the technical solution of the present utility model is that the outer wall of the dredging rod is movably plugged into the inner wall of the filter hole.

[0013] A further improvement of the technical solution of the present utility model is that the outer wall of the receiving ring is movably connected to the inner wall of the annular seat.

[0014] A further improvement of the technical solution of the present utility model is that the number of the first connecting rods and the second connecting rods is at least four.

[0015] A further improvement of the technical solution of the present utility model is that: the receiving ring is tapered as a whole, and the inner wall of the receiving ring is movably sleeved with the outer wall of the built-in filter plate.

[0016] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

[0017] 1. The utility model provides a bridge deck drain pipe device for a bridge, which utilizes the coordinated use of a receiving ring, a buffer return spring and a dredging plate pushing assembly, so that the receiving ring can use the pressure received to push the assembly through the dredging plate to act on the built-in dredging plate, so that the built-in dredging plate moves up to dredge the built-in filter plate, thereby preventing the dust and mud mixed in the rainwater from causing blockage of the pipe body.

[0018] 2. The utility model provides a bridge deck drain pipe device for bridges, which utilizes the tapered structure of the receiving ring as a whole to make the contact surface of the receiving ring smoother and not too raised when pedestrians or vehicles pass by, thereby avoiding bumps and collisions during walking and ensuring the safety of the device when used on the road.

DETAILED DESCRIPTION

[0024] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. 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 internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0025] The present invention is further described in detail below with reference to the embodiments:

[0026] Example 1

[0027] like Figure 1-4 As shown, the utility model provides a bridge deck drain pipe device, comprising a pipe body 1, an annular seat 2, a receiving ring 3, a built-in filter plate 5, and a built-in dredging plate 6. The receiving ring 3, the built-in filter plate 5, and the built-in dredging plate 6 are sequentially distributed inside the annular seat 2 from top to bottom. A dredging plate pushing assembly 7 for pushing the built-in dredging plate 6 upward to dredge the built-in filter plate 5 is provided below the receiving ring 3. The coordinated use of the receiving ring 3, the buffer return spring 4, and the dredging plate pushing assembly 7 enables the receiving ring 3 to act on the built-in dredging plate 6 through the dredging plate pushing assembly 7 with the help of the pressure received, so that the built-in dredging plate 6 moves upward to dredge the built-in filter plate 5, thereby preventing the dust and mud mixed in the rainwater from clogging the pipe body 1.

[0028] A positioning ring 8 is fixedly connected to the inner wall of the annular seat 2. A buffer return spring 4 is fixedly connected to the upper surface of the positioning ring 8. The end of the buffer return spring 4, which is away from the positioning ring 8, is fixedly connected to the bottom surface of the receiving ring 3. As the receiving ring 3 moves downward, it compresses the buffer return spring 4. When the pressure on the receiving ring 3 disappears, the receiving ring 3 is pushed back to its original position under the reaction force of the buffer return spring 4.

[0029] The bottom surface of the built-in filter plate 5 is provided with a filter hole 10, and the upper surface of the built-in dredging plate 6 is fixedly connected with a dredging rod 9 adapted to the filter hole 10. The built-in dredging plate 6 is provided with multiple groups of drainage holes for drainage to avoid unnecessary obstruction to the drainage work.

[0030] The dredging plate pushing assembly 7 includes a first connecting rod 12 whose top end is rotatably connected to the bottom of the built-in dredging plate 6, and the bottom end of the first connecting rod 12 is rotatably connected to a sliding ring 13, and one end of the sliding ring 13 is rotatably connected to a second connecting rod 15. The inner wall of the sliding ring 13 is movably connected to a guide slide rod 14, and one end of the guide slide rod 14 is fixedly connected to the inner wall of the annular seat 2.

[0031] The number of the first connecting rods 12 and the second connecting rods 15 is at least four.

[0032] Example 2

[0033] like Figure 1-4 As shown, based on Example 1, the utility model provides a technical solution: preferably, the bottom surface of the built-in filter plate 5 is fixedly connected to the inner wall of the annular seat 2 through the filter plate positioning rod 11, and the connection end between the filter plate positioning rod 11 and the inner wall of the annular seat 2 is located below the positioning ring 8.

[0034] The outer wall of the dredging rod 9 is movably connected to the inner wall of the filter hole 10.

[0035] The outer wall of the receiving ring 3 is movably connected to the inner wall of the annular seat 2 .

[0036] The receiving ring 3 is tapered as a whole, and the inner wall of the receiving ring 3 is movably connected to the outer wall of the built-in filter plate 5. The tapered structure of the receiving ring 3 as a whole makes the contact surface of the receiving ring 3 smoother and not too raised when pedestrians or vehicles pass by, thereby avoiding bumps and collisions during walking and ensuring the safety of the device when used on the road.

[0037] The working principle of the bridge deck drain pipe device for the bridge will be specifically described below.

[0038] like Figure 1-4As shown, during use, when a vehicle or pedestrian passes by, the receiving ring 3 moves downward under gravity. During the downward movement, the receiving ring 3 will push the first connecting rod 12 to deflect and move downward around its connecting axis. Then the first connecting rod 12 will push the sliding collar 13 to slide toward the center position on the outer wall of the guide slide rod 14. During the sliding process, the sliding collar 13 will push the second connecting rod 15 forward. Since the second connecting rod 15 is rotatably connected to the outer wall of the sliding collar 13, the second connecting rod 15 will deflect upward around the connection axis with the sliding collar 13 during the forward movement. The second connecting rod 15 deflects upward during the forward movement, which will push the built-in dredging plate 6 to move up. After the built-in dredging plate 6 moves up, it will drive the dredging rod 9 to move up and insert into the filter hole 10, thereby removing the dust and dirt accumulated in the filter hole 10, avoiding clogging of the built-in filter plate 5, and thus ensuring the normal drainage of the annular seat 2.

[0039] It should be noted that, in this document, relational terms such as first and second, etc., are used solely to distinguish one entity or operation from another, and do not necessarily require or imply any actual relationship or order between these entities or operations. Furthermore, the terms "comprise," "include," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or device comprising a set of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. Without further limitation, an element defined by the phrase "comprising a..." does not preclude the presence of other identical elements in the process, method, article, or device comprising the element. While the present invention has been generally described above, modifications or improvements based on this invention are readily apparent to those skilled in the art. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of this invention.
