Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, in particular to a water conservancy pipeline silt removal and drainage device. Background Art

[0002] High-pressure pipe dredging machines generate water flow through high-pressure water pumps. High-pressure water pumps pressurize water flow to extremely high pressure, forming a strong water flow. This water flow can overcome the resistance in the pipeline and penetrate deep into the pipeline. Its high-speed impact force can effectively break up the sediment, scale and blockage in the pipeline, and clear some of the broken materials out of the pipeline.

[0003] The high-pressure pipe dredging machine is mainly composed of a high-pressure water pipe, a nozzle, a power source and working accessories. In the prior art, most of the garbage cannot be discharged from the pipe by the jet of water after the pipe is dredged. For example, some tangled and intertwined garbage, although this type of garbage is cut by water flow to reduce its adhesion in the pipe, requires repeated flushing to be completely flushed out. For another example, due to the pipe shape of the pipe, the garbage in the pipe cannot be easily flushed out. Therefore, the utility model proposes a water conservancy pipe dredging and drainage device. Utility Model Content

[0004] The purpose of the utility model is to provide a water conservancy pipeline desilting and drainage device, in which a nozzle rotatably installed at one end of a joint rotates under the drive of a rotary drive mechanism, thereby driving a garbage winding member to rotate, so as to stir and entangle the tangled garbage such as leaves, plant branches, weeds, etc. in the pipeline, so as to facilitate the fragmentation of the garbage. At the same time, when the nozzle is recycled, the garbage entangled on the garbage winding member can be taken out of the pipeline, thereby improving the cleaning efficiency of the pipeline. In order to achieve the above technical features, the purpose of the utility model is achieved as follows:

[0005] A water conservancy pipeline silt removal and drainage device comprises a joint, one end of which is rotatably mounted with a nozzle connected to a rotary drive mechanism, a plurality of garbage windings are mounted on the outer side of the nozzle, and the other end of the joint is connected to a high-pressure water supply system via a high-pressure water pipe.

[0006] The rotary drive mechanism comprises an impeller fixedly mounted in the inner cavity of the nozzle, the rotation axis of the impeller coincides with the central axis of the nozzle, and a first nozzle is provided on the front end of the nozzle away from the joint.

[0007] A second nozzle is provided on the nozzle near the joint end, and an angle formed by a water flow ejection direction of the second nozzle and an axis of the joint is an acute angle.

[0008] One end of the garbage winding piece is fixed to the outside of the nozzle, and the other end of the garbage winding piece is a hook-shaped structure bent inwardly.

[0010] The utility model has the following beneficial effects:

[0011] 1. The nozzle rotatably mounted on one end of the joint rotates under the drive of the rotary drive mechanism, thereby driving the garbage winding member to rotate, so as to stir and entangle the tangled garbage such as leaves, plant branches, weeds, etc. in the pipeline, so as to facilitate the fragmentation of the garbage. At the same time, when the nozzle is recycled, the garbage entangled on the garbage winding member can be taken out of the pipeline, thereby improving the cleaning efficiency of the pipeline;

[0012] 2. After entering the inner cavity of the nozzle from the joint, the high-pressure water is sprayed out through the first nozzle to impact the garbage in the pipe.

[0025] The embodiments of the present utility model are further described below in conjunction with the accompanying drawings.

[0026] See attached Figure 1-3 In order to realize the above technical features, the purpose of the utility model is achieved as follows:

[0027] A water conservancy pipeline desilting and drainage device comprises a joint 1, one end of which is rotatably mounted with a nozzle 2, the nozzle 2 is connected to a rotary drive mechanism, a plurality of garbage winding members 4 are mounted on the outside of the nozzle 2, and the other end of the joint 1 is connected to a high-pressure water supply system through a high-pressure water pipe 3. During operation, on the one hand, the high-pressure water supply system provides high-pressure water to the nozzle 1, and the high-pressure water is sprayed through the nozzle 1 to impact the sediment, scaling and blockage in the pipeline, thereby clearing some fragments out of the pipeline; on the other hand, the nozzle 2 rotatably mounted on one end of the joint 1 rotates under the drive of the rotary drive mechanism, thereby driving the garbage winding member 4 to rotate, so as to stir and entangle the tangled garbage such as leaves, plant branches, weeds, etc. in the pipeline, so as to facilitate the fragmentation of the garbage, and at the same time, when the nozzle 2 is recycled, the garbage wound on the garbage winding member 4 can be taken out of the pipeline, thereby improving the cleaning efficiency of the pipeline.

[0028] Furthermore, the rotation drive mechanism includes an impeller 5 fixedly mounted in the inner cavity of the nozzle 2, the rotation axis of the impeller 5 coincides with the central axis of the nozzle 2, and a first nozzle 2a is provided on the front end of the nozzle 2 away from the joint 1. After high-pressure water enters the inner cavity of the nozzle 2 from the joint 1, it is sprayed out through the first nozzle 2a to impact the garbage in the pipeline. The high-pressure water flows through the surface of the impeller 5 and impacts the impeller 5, thereby driving the impeller 5, the nozzle 2 and the garbage winding member 4 to rotate, and realizing rotation drive using high-pressure water as the power medium.

[0029] Furthermore, a second nozzle 2b is provided on the nozzle 2 near the end of the joint 1, and the angle a formed by the water flow ejection direction of the second nozzle 2b and the axis of the joint 1 is an acute angle; in the process of the second nozzle 2b spraying high-pressure water, a reaction force is provided for the nozzle 2, thereby pushing the nozzle 2 to move along the pipeline and providing power for the linear movement of the nozzle 2.

[0030] Furthermore, one end of the garbage winding member 4 is fixed to the outside of the nozzle 2, and the other end of the garbage winding member 4 is a hook-shaped structure bent inwardly, so as to facilitate the hooking and collection of garbage.

[0031] Furthermore, a plurality of cutting blades 6 are provided on the outer side of each of the garbage winding members 4, so that the rotation of the garbage winding members 4 drives the cutting blades 6 to decompose the garbage entangled in the pipeline, so as to facilitate the cleaning of the garbage.

[0032] The impeller 5 includes a plurality of blades 5a. Figure 3-4 , the common plane that each blade 5a can contact is the rotation plane 7, and the rotation plane 7 is perpendicular to the central axis of the nozzle 2. Each blade 5a includes a first sub-blade 5a1 and a second sub-blade 5a2 formed by bending. The inclination angle formed by the first sub-blade 5a1 and the rotation plane 7 is controlled to be about 45°, and the inclination angle formed by the second sub-blade 5a2 and the rotation plane 7 is controlled to be about 95°. The dotted line b is the vertical line of the first sub-blade 5a1, the dotted line c is the vertical line of the second sub-blade 5a2, and the dotted line d is the vertical line of the rotation plane 7. The vertical lines of the first sub-blade 5a1 and the second sub-blade 5a2 intersect with the vertical line of the rotation plane 7 respectively to form an inclination angle. The water flow enters the inner cavity of the nozzle 2 perpendicular to the rotation plane 7. When the water flow flows through the impeller 5, the second blade 14 guides the water flow, so that the water flow obliquely hits the second sub-blade 5a2 and obliquely hits the first sub-blade 5a1, so that the blade and the nozzle rotate, thereby converting the water energy into rotational mechanical energy. It should be noted that the rotating plane 7 and the vertical line are not structures of the present invention, but are auxiliary planes and auxiliary lines introduced only for the convenience of description, and therefore are distinguished by dotted lines.

[0033] For further information, see Figure 5 The joint 1 is provided with a threaded section, which is used to be disassembled and connected to one end of the high-pressure water pipe 3. The inner cavity of the joint 1 is provided with a main channel 1a, a first branch channel 1b and a second branch channel 1c, the first branch channel 1b and the second branch channel 1c are both connected to the main channel 1a, the first branch channel 1b is used to guide the water flow to the impeller, and the second branch channel 1c is used to guide the water flow to flow from the gap of the impeller to the first nozzle 2a, so as to reasonably distribute the use of high-pressure water.
