Abstract
Description
Technical Field
[0001] The utility model is applicable to the technical field of water supply and drainage of green buildings, and particularly relates to a drainage anti-blocking structure. Background Art
[0002] At present, in order to prevent rainwater from accumulating on the ground inside the courtyard of a family house, causing the road surface to be slippery for a long time and affecting safety, corresponding drainage pipes are often set inside the courtyard to drain the accumulated rainwater.
[0003] However, when drainage pipes are used to drain rainwater accumulated on the ground in the courtyard, in order to ensure the normal entry of rainwater, the top of the drainage pipe is often opened. Although this setting increases the discharge speed of rainwater, it cannot block large debris such as fallen leaves and stones, which can easily cause solid impurities to block the water inlet of the pipe. Once the debris accumulates inside the pipe, it will not only affect the discharge flow speed of rainwater, but also affect the subsequent cleaning efficiency. Therefore, we propose a drainage anti-blocking structure. Utility Model Content
[0004] The main purpose of the utility model is to provide a drainage anti-blocking structure, which can effectively solve the problems in the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A drainage anti-blocking structure comprises a connecting plate, a blocking rod is fixedly installed on the bottom surface of the connecting plate, and the blocking rods are in a plurality of groups, a first fixing ring is fixedly installed between the outer sides of the middle ends of the blocking rods, and a second fixing ring is fixedly installed between the outer sides of the bottoms of the blocking rods;
[0007] A fixing plate is fixedly mounted on the outer surface of the bottom of the second fixing ring, and the number of the fixing plates is four groups, a guide rod is fixedly mounted on the middle end surface of the side of each fixing plate, a sliding sleeve is fixedly and slidably sleeved on the outer surface of each guide rod, a push rod is hingedly mounted on the top surface of each sliding sleeve through a rotating shaft, a transmission rod is fixedly mounted on the outer end surfaces of each sliding sleeve, and a tightening arc plate is fixedly mounted between the ends of each two groups of transmission rods away from the sliding sleeve;
[0008] The middle end of the connecting plate is screwed with an adjusting bolt through a thread, the bottom of the adjusting bolt is rotatably mounted with a lifting plate through a bearing, and the top surface of the push rod is hinged with the bottom surface of the lifting plate through a rotating shaft.
[0009] By adopting the above technical solution, through the transmission conversion action of the push rod and the blocking action of multiple sets of blocking rods, it is ensured that the arc plate can stably fit the inner wall of the pipe to be installed, so that the multiple sets of blocking rods can block debris outside the drainage pipe, so that rainwater can flow normally through the blocking rods while the debris mixed inside it will not flow into the pipe at will and cause blockage.
[0010] As an optional solution of the technical solution of the present application, sliding grooves are provided inside both ends of the side edges of each of the fixing plates, and the transmission rod is slidably installed inside the sliding groove.
[0011] By adopting the above technical solution, the movement stability of the transmission rod is ensured by the guiding sliding action of the sliding groove on the transmission rod.
[0012] As an optional solution of the technical solution of the present application, guide grooves are provided at both ends of the inner side of each sliding sleeve, and guide blocks are fixedly installed on the outer end surfaces of each guide rod, and the guide blocks are slidably inserted into the guide grooves.
[0013] By adopting the above technical solution, the movement stability of the sliding sleeve is ensured by the guiding sliding action of the guide groove on the guide block.
[0014] The lifting plate is located inside the blocking rod, and the push rod is tilted between the bottom of the lifting plate and the top of the sliding sleeve.
[0015] By adopting the above technical solution, the vertical moving force of the lifting plate can be converted into a horizontal driving force on the sliding sleeve through the structural setting of the pushing rod.
[0016] Compared with the prior art, the utility model has the following beneficial effects:
[0017] 1. A drainage anti-blocking structure of the technical solution of the present application, by arranging multiple groups of arc-shaped blocking rods at the bottom of the connecting plate, and combining the rotating shaft to connect the two ends of the pushing rod with the lifting plate and the sliding sleeve respectively, so that after the operator screws the adjusting bolt to drive the lifting plate to move vertically, the pushing rod can convert the vertical movement force of the lifting plate into a horizontal pushing force for the sliding sleeve, thereby allowing the multiple groups of tight arc plates to move synchronously towards or relative to each other under the second fixing ring, ensuring that the tight arc plates can stably fit the inner wall of the pipe to be installed, so that the multiple groups of blocking rods can block debris from the outside of the drainage pipe, so that rainwater can flow normally through the blocking rods while the debris mixed inside them will not flow into the pipe at will to cause blockage.
[0018] 2. A drainage anti-blocking structure of the technical solution of the present application, by slidingly inserting the guide block into the guide groove, combined with the guiding sliding action of the guide groove on the guide block, enables the sliding sleeve to move only along the outer side of the guide rod after being pushed without being offset, thereby ensuring that the arc plate can fully fit the inner wall of the pipe and provide sufficient stability for the installation of the entire mechanism.
