Description

Technical Field

[0001] This application relates to the field of water supply and drainage pipelines, and particularly relates to an external protection structure for water supply and drainage pipelines. Background Art

[0002] Water supply and drainage pipelines are pipelines for transporting and distributing industrial water supply and domestic drinking water, as well as collecting, transporting, and discharging industrial wastewater, domestic sewage, and rainwater. Water supply and drainage pipelines are an inalienable part of the water supply and drainage system and play an important role in the entire water supply and drainage system. It includes the pipeline (channel) system itself and various structure works on the pipeline (channel) system (such as pumping stations, reservoirs, pipe bridges, gate wells, sewage inspection wells, rainwater inlets, etc.). The project investment accounts for most of the total investment of the water supply and drainage system project.

[0003] Currently, the Chinese patent with the patent publication number: CN211624499U discloses a water supply and drainage pipeline connection device. This utility model discloses a water supply and drainage pipeline, including a hollow pipe body. One end of the pipe body is provided with a male joint, and the other end of the pipe body is provided with a female joint; a conical head is provided at the front end of the male joint, a conical opening is provided at the front end of the female joint, and a conical sealing sleeve matching the conical head is sleeved in the conical opening; a first flange is sleeved on the circumference of the male joint near the front end, and a plurality of first card slots are provided on the rear end surface of the first flange along the circumferential direction, and first clamping plates are clamped in the first card slots; a second flange is sleeved on the circumference of the female joint near the front end, and a plurality of second card slots are provided on the rear end surface of the second flange along the circumferential direction, and second clamping plates are clamped in the second card slots; the male joint of the pipe body and the female joint of another pipe body are connected by a first stud passing through the first clamping plate, the first flange, the second flange, and the second clamping plate in sequence. The water supply and drainage pipeline of this utility model has a simple structure, convenient connection, good sealing effect, and strong practicability, and has a high popularization and application value.

[0004] Although the above solution has the above advantages, the disadvantage of the above solution is that when using water supply and drainage pipes, since some pipes are exposed, sometimes the water supply and drainage pipes will inevitably be accidentally impacted externally. The pipes have no external protection structure, and over time, the pipes are easily damaged and cracked. Some wrap some buffer parts, such as rubber, outside the pipes to provide protection for the pipes, but the protection effect of a single buffer part is poor. Moreover, when using the water supply and drainage pipes to drain water, sometimes due to the accumulation of some large floating objects inside the pipes, the pipes are blocked. At this time, the pipes need to be repaired, affecting the use of the pipes. Summary of the Utility Model

[0005] An external protection structure for water supply and drainage pipes provided by the present application protects the pipes when they are accidentally impacted externally during the use of the water supply and drainage pipes, preventing the pipes from being damaged and ruptured, affecting the drainage function, and having a good protection effect. When draining water using the water supply and drainage pipes, the floating objects in the water are cut and crushed to prevent their accumulation from causing pipe blockage and reducing the frequency of pipe maintenance.

[0006] To achieve the above object, the present application adopts the following technical solutions: An external protection structure for water supply and drainage pipes, the protection structure includes:

[0007] A pipe body and a first protection frame;

[0008] Two bosses are respectively arranged on both sides of the first protection frame by screws, and two first connecting shafts are fixedly arranged at the inner walls of the two bosses. By rotating the screws on the two bosses, the two bosses are fixed on the first protection frame or removed from the first protection frame;

[0009] Multiple transmission rods are respectively sleeved on the outer surfaces of the multiple first connecting shafts, and second connecting shafts are movably embedded on the outer surfaces of the multiple transmission rods. The multiple transmission rods can rotate around the multiple first connecting shafts or the multiple second connecting shafts;

[0010] Multiple sliding plates are respectively fixedly arranged at both ends of the multiple second connecting shafts, and the multiple sliding plates are divided into two groups in pairs. Support rods are movably embedded at the inner walls of the two groups of sliding plates, and the multiple sliding plates can slide on the outer surfaces of the two support rods;

[0011] Multiple bottom plates are respectively fixedly arranged at both ends of the two support rods, and a second protection frame is fixedly arranged on one side of the multiple bottom plates. The multiple transmission rods push the multiple sliding plates to slide on the outer surfaces of the two support rods, further causing the multiple sliding plates and the multiple bottom plates to respectively squeeze multiple second springs;

[0012] Two hollow cylinders are respectively fixedly arranged on the opposite sides of the first protection frame and the second protection frame, and circular plates are movably embedded at the inner walls of the two hollow cylinders. The two circular plates can respectively slide at the inner walls of the two hollow cylinders.

[0013] As a further improvement of the present application: Second springs are fixedly arranged on one side of the multiple sliding plates, and the multiple second springs are respectively sleeved on the outer surfaces of the two support rods. When the multiple second springs are squeezed, they will generate a reverse force, which will reduce the force received by the first protection frame or the second protection frame and improve the protection effect of the first protection frame and the second protection frame.

[0014] As a further improvement of the present application: First springs are fixedly arranged on the inner walls of the two hollow cylinders, and one sides of the two first springs are respectively fixedly arranged on the opposite sides of the two circular plates. The two first springs are compressed to generate reverse acting forces, reducing the forces received by the first protection frame or the second protection frame, and further improving the protection effects of the first protection frame and the second protection frame.

[0015] As a further improvement of the present application: Connecting rods are fixedly arranged on the opposite sides of the two circular plates, and arc-shaped pressing plates are fixedly arranged on the opposite sides of the two connecting rods. The elastic forces generated by the two first springs compress the two circular plates, and through the two connecting rods, the two arc-shaped pressing plates are closely attached to the outer surface of the pipeline body.

[0016] As a further improvement of the present application: A plurality of fixing rods are fixedly arranged on the inner wall of the pipeline body, and collar rings are fixedly arranged at one ends of the plurality of fixing rods. The plurality of fixing rods support the collar rings, so that the collar rings and the pipeline body are connected together.

[0017] As a further improvement of the present application: A rotating rod is arranged on the inner wall of the collar ring through a bearing, and a turbine blade is installed at one end of the rotating rod. A bearing is fixedly sleeved on the inner wall of the collar ring, and the inner wall of the bearing is sleeved on the outer surface of the rotating rod. When the rotating rod rotates, the collar ring does not rotate. The water discharged from the pipeline will flow through the turbine blade, and the kinetic energy of the water flow will be transmitted to the turbine blade. The collar ring can rotate through the bearing, and at this time, the turbine blade rotates.

[0018] As a further improvement of the present application: A connecting ring is fixedly arranged at the end of the turbine blade away from the turbine blade, and a plurality of blades are fixedly arranged on the outer surface of the connecting ring. The connecting ring supports the plurality of blades, so that the plurality of blades and the rotating rod are connected together. When the plurality of blades rotate, the cutting edges on the rotating blades cut the floating objects in the water, making the volume of the floating objects smaller and then discharging them, preventing their accumulation from causing pipeline blockage and reducing the frequency of pipeline maintenance.

[0019] As a further improvement of the present application: The inner walls of the two arc-shaped pressing plates are arranged on the outer surface of the pipeline body. When using the protection structure, the two arc-shaped pressing plates are respectively closely attached to the outer surface of the pipeline body. At this time, the screw nails on the two bosses are rotated, so that the two bosses are fixed on the first protection frame. The elastic forces generated by the two first springs compress the two circular plates, and through the two connecting rods, the two arc-shaped pressing plates are closely attached to the outer surface of the pipeline body to support the protection structure.

[0020] Compared with the prior art, the advantages and positive effects of the present application are as follows.

[0021] 1. In this application, when using the protection structure, two arc-shaped pressing plates are respectively pressed against the outer surface of the pipeline body. At this time, turn the threaded nails on the two bosses so that the two bosses are fixed on the first protection frame. When the pipeline is accidentally impacted externally, the first protection frame and the second protection frame provide a protection effect for the pipeline body, preventing the pipeline body from directly contacting the stress point, protecting the pipeline body from being damaged by the impact. Multiple transmission rods can rotate respectively around multiple first connecting shafts or multiple second connecting shafts. When the first protection frame or the second protection frame is impacted, the force received causes the positions of the multiple transmission rods to change. Multiple sliding plates can slide on the outer surfaces of the two support rods. At this time, the multiple transmission rods push the multiple sliding plates to slide on the outer surfaces of the two support rods, further causing the multiple sliding plates and the multiple bottom plates to respectively squeeze the multiple second springs. At this time, the multiple second springs will generate a reverse force when being squeezed, which will reduce the force received by the first protection frame or the second protection frame and improve the protection effect of the first protection frame and the second protection frame. The two circular plates can slide on the inner walls of the two hollow cylinders respectively. When the first protection frame or the second protection frame is impacted, it will push the two hollow cylinders to move, further causing the two circular plates and the inner walls of the two hollow cylinders to squeeze the two first springs. The two first springs will also generate a reverse force when being squeezed, which will also reduce the force received by the first protection frame or the second protection frame and further improve the protection effect of the first protection frame and the second protection frame. Moreover, the elastic force generated by the two first springs squeezes the two circular plates, and through the two connecting rods, the two arc-shaped pressing plates are pressed against the outer surface of the pipeline body to support the protection structure. Thus, when using a water supply and drainage pipeline and the pipeline is accidentally impacted externally, the pipeline is protected to prevent it from being damaged and ruptured, affecting the drainage function, and the protection effect is better.

[0022] 2. In this application, when using the pipeline, multiple fixing rods support the collar, enabling the collar to be connected to the pipeline body, and the collar can rotate through a bearing. The water discharged from the pipeline will flow through the turbine blades, and the kinetic energy of the water flow will be transmitted to the turbine blades. At this time, the turbine blades rotate, further driving the rotating rod to rotate, and driving the blade to rotate through the connecting ring. When the multiple blades rotate, the cutting edges on the rotating blades cut the floating objects in the water, making the volume of the floating objects smaller and then discharging them. Thus, when draining water using a water supply and drainage pipeline, the floating objects in the water are cut and crushed to prevent them from accumulating and causing pipeline blockage, reducing the frequency of pipeline maintenance.

[0032] In order to more clearly understand the above-mentioned objects, features and advantages of this application, the following further describes this application in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other.

[0033] Many specific details are set forth in the following description in order to fully understand this application. However, this application can also be implemented in other ways different from those described herein. Therefore, this application is not limited by the specific embodiments disclosed in the following specification.

[0034] Embodiment 1, as Figures 1 to 8 shown, this application provides an external protection structure for water supply and drainage pipes, and this protection structure includes:

[0035] Pipe body 1 and first protection frame 2;

[0036] Two bosses 201 are respectively arranged on both sides of the first protection frame 2 by screws, and two first connecting shafts 202 are fixedly arranged at the inner walls of the two bosses 201. By rotating the screws on the two bosses 201, the two bosses 201 are fixed on the first protection frame 2 or removed from the first protection frame 2;

[0037] Multiple transmission rods 203 are respectively sleeved on the outer surfaces of multiple first connecting shafts 202, and multiple second connecting shafts 204 are movably embedded on the outer surfaces of the multiple transmission rods 203. The multiple transmission rods 203 can rotate respectively with the multiple first connecting shafts 202 or the multiple second connecting shafts 204 as axes;

[0038] Multiple sliding plates 205 are respectively fixedly arranged at both ends of the multiple second connecting shafts 204, and the multiple sliding plates 205 are divided into two groups in pairs. Support rods 206 are movably embedded at the inner walls of the two groups of sliding plates 205, and the multiple sliding plates 205 can slide on the outer surfaces of the two support rods 206;

[0039] Multiple bottom plates 207 are respectively fixedly arranged at both ends of the two support rods 206, and a second protection frame 208 is fixedly arranged on one side of the multiple bottom plates 207. The multiple transmission rods 203 push the multiple sliding plates 205 to slide on the outer surfaces of the two support rods 206, further causing the multiple sliding plates 205 and the multiple bottom plates 207 to respectively squeeze multiple second springs 214;

[0040] Two hollow cylinders 209 are respectively fixedly arranged on the opposite sides of the first protection frame 2 and the second protection frame 208, and circular plates 210 are movably embedded at the inner walls of the two hollow cylinders 209. The two circular plates 210 can respectively slide at the inner walls of the two hollow cylinders 209.

[0041] As Figures 1 to 8 shown, second springs 214 are fixedly arranged on one side of the multiple sliding plates 205. The multiple second springs 214 are respectively sleeved on the outer surfaces of the two support rods 206. When the multiple second springs 214 are squeezed, they will generate a reverse force, which will reduce the force received by the first protection frame 2 or the second protection frame 208, improving the protection effect of the first protection frame 2 and the second protection frame 208.

[0042] As Figures 1 to 8 shown, first springs 213 are fixedly arranged at the inner walls of the two hollow cylinders 209. One sides of the two first springs 213 are respectively fixedly arranged on the opposite sides of the two circular plates 210. When the two first springs 213 are squeezed, they generate a reverse force, reducing the force received by the first protection frame 2 or the second protection frame 208, and further improving the protection effect of the first protection frame 2 and the second protection frame 208.

[0043] As Figures 1 to 8As shown in the figure, connecting rods 211 are fixedly arranged on one side of each of the two circular plates 210 facing each other. Arc-shaped pressing plates 212 are fixedly arranged on one side of each of the two connecting rods 211 facing each other. The elastic forces generated by the two first springs 213 squeeze the two circular plates 210, and through the two connecting rods 211, the two arc-shaped pressing plates 212 are closely attached to the outer surface of the pipeline body 1.

[0044] As Figures 1 to 8 shown in the figure, a plurality of fixing rods 3 are fixedly arranged at the inner wall of the pipeline body 1. Sleeve rings 301 are fixedly arranged at one end of each of the plurality of fixing rods 3. The plurality of fixing rods 3 support the sleeve rings 301, so that the sleeve rings 301 are connected to the pipeline body 1 together.

[0045] As Figures 1 to 8 shown in the figure, a rotating rod 302 is arranged on the inner wall of the sleeve ring 301 through a bearing. A turbine blade 305 is installed at one end of the rotating rod 302. A bearing is fixedly sleeved on the inner wall of the sleeve ring 301, and the inner wall of the bearing is sleeved on the outer surface of the rotating rod 302. When the rotating rod 302 rotates, the sleeve ring 301 does not rotate. The water discharged from the pipeline will flow through the turbine blade 305, and the kinetic energy of the water flow will be transmitted to the turbine blade 305. The sleeve ring 301 can rotate through the bearing, and at this time, the turbine blade 305 rotates.

[0046] As Figures 1 to 8 shown in the figure, a connecting ring 303 is fixedly arranged at one end of the turbine blade 305 away from the turbine blade 305. A plurality of blades 304 are fixedly arranged on the outer surface of the connecting ring 303. The connecting ring 303 supports the plurality of blades 304, so that the plurality of blades 304 are connected to the rotating rod 302 together. When the plurality of blades 304 rotate, the cutting edges on the rotating blades 304 cut the floating objects in the water, making the volume of the floating objects smaller and then discharging them, preventing their accumulation from causing pipeline blockage and reducing the frequency of pipeline maintenance.

[0047] As Figures 1 to 8 shown in the figure, the inner walls of the two arc-shaped pressing plates 212 are arranged on the outer surface of the pipeline body 1. When using the protection structure, the two arc-shaped pressing plates 212 are respectively closely attached to the outer surface of the pipeline body 1. At this time, turn the threaded nails on the two bosses 201 so that the two bosses 201 are fixed on the first protection frame 2. The elastic forces generated by the two first springs 213 squeeze the two circular plates 210, and through the two connecting rods 211, the two arc-shaped pressing plates 212 are closely attached to the outer surface of the pipeline body 1 to support the protection structure.

[0048] Working principle: When using the protection structure, the two arc-shaped pressing plates 212 are respectively pressed against the outer surface of the pipeline body 1. At this time, the threaded nails on the two bosses 201 are rotated so that the two bosses 201 are fixed on the first protection frame 2. When the pipeline is accidentally impacted externally, the first protection frame 2 and the second protection frame 208 provide a protection effect for the pipeline body 1, preventing the pipeline body 1 from directly contacting the force point, protecting the pipeline body 1 from being damaged by the impact. The multiple transmission rods 203 can rotate respectively around the multiple first connecting shafts 202 or the multiple second connecting shafts 204. When the first protection frame 2 or the second protection frame 208 is impacted, the force received causes the positions of the multiple transmission rods 203 to change. The multiple sliding plates 205 can slide on the outer surfaces of the two support rods 206. At this time, the multiple transmission rods 203 push the multiple sliding plates 205 to slide on the outer surfaces of the two support rods 206, further causing the multiple sliding plates 205 and the multiple bottom plates 207 to respectively squeeze the multiple second springs 214. At this time, the multiple second springs 214 will generate a reverse force when being squeezed, which will reduce the force received by the first protection frame 2 or the second protection frame 208, improving the protection effect of the first protection frame 2 and the second protection frame 208. The two circular plates 210 can slide on the inner walls of the two hollow cylinders 209 respectively. When the first protection frame 2 or the second protection frame 208 is impacted, it will push the two hollow cylinders 209 to move, further causing the two circular plates 210 and the inner walls of the two hollow cylinders 209 to squeeze the two first springs 213. The two first springs 213 will also generate a reverse force when being squeezed, which will also reduce the force received by the first protection frame 2 or the second protection frame 208, further improving the protection effect of the first protection frame 2 and the second protection frame 208. And the elastic force generated by the two first springs 213 squeezes the two circular plates 210, and through the two connecting rods 211, the two arc-shaped pressing plates 212 are pressed against the outer surface of the pipeline body 1, supporting the protection structure. Thus, when using the water supply and drainage pipeline and the pipeline is accidentally impacted externally, the pipeline is protected to prevent the pipeline from being damaged and ruptured, affecting the drainage function, and the protection effect is good. When using the pipeline, the multiple fixing rods 3 support the collar 301, so that the collar 301 is connected to the pipeline body 1, and the collar 301 can rotate through the bearing. The water discharged from the pipeline will flow through the turbine blades 305, and the kinetic energy of the water flow will be transmitted to the turbine blades 305. At this time, the turbine blades 305 rotate, further driving the rotating rod 302 to rotate, and driving the blade 304 to rotate through the connecting ring 303. When the multiple blades 304 rotate, the cutting edges on the rotating blades 304 cut the floating objects in the water, making the volume of the floating objects smaller and then discharging them. Thus, when draining water using the water supply and drainage pipeline, the floating objects in the water are cut and crushed to prevent them from accumulating and causing pipeline blockage, reducing the frequency of pipeline maintenance.

[0049] The above are only the preferred embodiments of the application, and are not intended to limit the present utility model in other forms. Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as they do not depart from the technical solution content of the present utility model, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
