Description

Technical Field

[0001] The present application relates to the technical field of municipal bridge drainage pipes, and specifically to a municipal bridge rapid drainage pipe. Background Art

[0002] A Chinese patent (publication number: CN 215721681 U) discloses a municipal bridge rapid drainage pipe, which has a buffering protection to avoid pipeline failure caused by collision or geological changes. By setting a connecting part, the connection between the pipe and the ground is more stable and convenient for disassembly and assembly. By setting a welding part, the drainage pipe and the water inlet pipe are connected to each other, which improves the airtightness of the equipment and prevents water seepage. However, in the above document, the filter plate is clamped in the grooves on both sides of the mounting part by two sets of clamping parts, so that the filter plate is clamped on the inner side of the mounting part. However, because the two sets of clamping parts are clamped in the grooves, since sufficient space is not reserved in the mounting part, it is more troublesome and laborious for the staff to disassemble the filter plate. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] See also Figure 2-3 The limiting assembly in this embodiment includes two groups of positioning blocks 62, support blocks 63 fixedly installed at the upper and lower ends of the positioning blocks 62, and a pulling reset assembly fixedly installed on the right sides of the two positioning blocks 62 in the same group.

[0031] Among them, the support plate 5 is ring-shaped, and four placement grooves are opened on the right side of the support plate 5. The connecting block 61 is located inside the placement groove and plugged therein, so that the filter plate 6 can be stably placed on the inner side of the support plate 5 through the four connecting blocks 61, so that the support plate 5 can support the filter plate 6.

[0032] In addition, positioning grooves are provided on the upper and lower walls of the inner cavity of the placement groove, and the positioning block 62 is inserted into the interior of the positioning groove. By moving the positioning block 62 into the positioning groove in the placement groove, the front and rear connecting blocks 61 can be fixed in the placement groove of the support plate 5, so that the filter plate 6 can be fixed to the inner side of the support plate 5, and through holes are provided at the upper and lower ends of the connecting block 61. The positioning block 62 can be moved out of the interior of the connecting block 61 through the through holes and can be moved into the positioning groove in the placement groove.

[0033] In addition, two sliding grooves are provided on the left and right walls of the inner cavity of the front and rear connecting blocks 61, and the support block 63 is slidably connected to the inside of the sliding groove so that the support block 63 can support the positioning block 62 to prevent it from falling out, thereby reducing the positioning block 62 from falling out from the inside of the connecting block 61.

[0034] See also Figure 3 The pull reset assembly in this embodiment includes a pull block 68, two concave rods 66, a sleeve rod 64, and a pull plate 67 fixedly installed and hinged between the upper and lower ends of the pull block 68. The outer surface of the sleeve rod 64 is sleeved with a reset spring 65.

[0035] Secondly, a sliding hole is opened at the right end of the front and rear connecting blocks 61, and the pulling block 68 is slidably connected to the inside of the sliding hole, so that the pulling block 68 can move into or out of the interior of the connecting block 61 through the sliding hole.

[0036] In addition, the upper and lower positioning blocks 62 are hollow inside and one side opposite to the other is missing, so that the positioning blocks 62 can slide outside the sleeve rod 64 , so that the two positioning blocks 62 can squeeze the return spring 65 .

[0037] Moreover, sliding grooves are provided on the opposite sides of the front and rear pull plates 67, and the concave rod 66 is slidably connected to the sliding grooves so that the pull plate 67 is connected to the concave rod 66, and the concave rod 66 is fixed to the right side wall of the positioning block 62, so that the pull plate 67 can pull the positioning block 62 to move through the concave rod 66.

[0038] See also Figure 4 The protection assembly 4 in this embodiment includes two protection plates 41, two connecting plates 42, and the two connecting plates 42 are respectively fixed to the upper and lower ends of the drain pipe 1, three connecting rods 43 fixedly installed on the opposite sides of the two protection plates 41, and a pressure plate 44 fixedly installed on the outside of the three connecting rods 43 in the same group, and the outer surface of the connecting rod 43 is adjusted with a buffer spring 45.

[0039] At the same time, anti-drop blocks are fixed at the opposite ends of the two groups of connecting rods 43, and three through holes are opened on the opposite sides of the two connecting plates 42. The connecting rods 43 are slidably connected to the inner sides of the through holes, so that the connecting rods 43 can move into the interior of the connecting plates 42 through the through holes, and the diameter of the through holes is smaller than the diameter of the anti-drop blocks, which can prevent the connecting rods 43 from falling off from the connecting plates 42.

[0040] Furthermore, three communication holes are formed at opposite ends of the two pressing plates 44 , and the connecting rod 43 is fixed inside the communication holes so that the pressing plates 44 can be fixed outside the connecting rod 43 .

[0041] The working principle of the above embodiment is:

[0042] When in use, when the filter plate 6 needs to be disassembled, the staff pulls the two pulling blocks 68 to move rightward, so that the two pulling blocks 68 pull the upper and lower groups of concave rods 66 to move backwards through the two groups of pulling plates 67, so that the upper and lower groups of concave rods 66 move backwards and drive the upper and lower groups of positioning blocks 62 to move backwards, so that the positioning blocks 62 can be moved out of the positioning grooves in the placement grooves and moved into the interior of the connecting block 61. When the upper and lower groups of positioning blocks 62 move backwards, the sleeve rod 64 gradually moves into the interior of the two positioning blocks 62 of the same group, so that the upper and lower positioning blocks 62 can squeeze the reset spring 65, and the staff can pull the filter plate 6 out from the inner side of the support plate 5 and the inside of the water inlet pipe 3, which is convenient for cleaning and replacement of the filter plate 6;

[0043] When impacted, the protective plate 41 pushes the three connecting rods 43 of the same group into the interior of the connecting plate 42, so that the connecting plate 42 cooperates with the pressure plate 44 to squeeze the buffer spring 45, thereby providing a buffer for the drainage pipe 1 and avoiding pipeline failure caused by collision or geological changes.
