Description

Technical Field

[0001] The invention relates to the technical field of pipeline drainage, and in particular to an automatic cleaning device for crystals in a pipeline. Background Art

[0002] Drainage pipes play a key role in urban infrastructure. They effectively discharge sewage, rainwater and wastewater from cities and industrial areas to appropriate locations such as sewage treatment plants or rivers to protect the environment and public health. By preventing sewage from accumulating in public areas, drainage pipes reduce the risk of disease transmission and maintain urban hygiene. At the same time, they help prevent urban waterlogging and flooding and reduce disaster losses. This system supports the normal operation and development of cities, improves the quality of life of residents, and provides security for commerce and industry. Therefore, it is crucial in maintaining urban safety, environmental protection, economic benefits and social welfare. However, field surveys have found that there is an increasingly prominent problem of crystal blockage in the drainage system in my country's pipelines. Drainage pipe blockage is mainly manifested in the continuous accumulation of crystals in the drainage pipes, which gradually increases over time. If these crystals are not handled in time, the drainage pipes will be blocked, the water pressure will continue to increase, and leakage of varying degrees may occur. Therefore, the drainage pipes must be unobstructed during operation to ensure their safe operation, the safety of people's lives and property, and the order of urban operation.

[0003] There is a patent in the prior art, patent number CN201611264591.9, the present invention discloses a pipe cleaner, including: a body, a support wheel assembly, a cleaning brush assembly and a rubber cup; the body includes: a vibration assembly and a power assembly connected to the vibration assembly; the vibration assembly includes: a mandrel, a sleeve, a vibration spring, a piston terminal and a first housing; the power assembly includes: an end cover, a rotating shaft, a second housing, turbine blades, a fixed valve and a moving valve; the support wheel assembly is installed on the outer wall of the first housing and / or the second housing. The beneficial effect brought by the present invention is that it can efficiently complete the cleaning work inside the pipeline.

[0004] At present, the cleaning methods of crystals inside pipelines mainly include power robot cleaning, wind cleaning, chemical cleaning and ultrasonic cleaning instead of manual cleaning. However, the existing technologies have certain problems: 1. The pipeline cleaning procedure is complicated and the cleaning frequency is high; 2. The cleaning process may cause corrosion, fatigue, damage or other adverse effects on the materials inside the pipeline; 3. Manual cleaning is inefficient, time-consuming and labor-intensive, and the cleaning range is not large enough; 4. The cleaning equipment itself is expensive, and requires professional personnel to operate and maintain it, and requires external forces such as electricity to drive it, which makes the cleaning cost too high. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide an automatic cleaning device for crystals in pipelines to solve the problems of complex, time-consuming and labor-intensive procedures for cleaning crystals in pipelines.

[0006] In order to achieve the above object, the present invention provides the following technical solutions: A device for automatically cleaning crystals in a drainage pipe, characterized in that it comprises: turbine blades, a first circular shaft, a first bearing, a vertical rod, a connecting rod, a second circular shaft, a second bearing, a transmission rod, a crank, a shaft rod, a slide rail, bristles and a base; wherein the first circular shaft and the turbine blades are of an integrated design; a first bearing is provided at the center of the first circular shaft; the upper end of the first circular shaft is fixedly connected to the inner wall of the pipe through a vertical rod, and the lower end is fixedly connected to the upper end of the connecting rod; the lower end of the connecting rod is fixedly connected to the second circular shaft; a second bearing is provided at the center of the second circular shaft, and the second circular shaft is fixedly connected to the bottom of the pipe through a base; a transmission rod is sleeved on the connecting rod; both ends of the transmission rod are sleeved on the shaft rod; the shaft rod and the crank are of an integrated design; the crank is arranged and mounted on a slide rail fixedly connected to the side wall of the pipe; bristles are evenly installed at the bottom of the crank.

[0007] The beneficial effect of adopting the above technical solution is that when liquid passes through the pipeline, the liquid impacts the turbine blades, the turbine blades begin to generate circular motion, and the first circular shaft fixed inside the turbine blades begins to rotate, so that the second circular shaft connected to the first circular shaft by a connecting rod simultaneously rotates, and the transmission rod sleeved on the second circular shaft rotates around the sleeve point, thereby promoting the linear motion of the crank hinged on the transmission rod, so that the bristles evenly arranged on the lower part of the crank begin to clean the inner wall of the pipeline.

[0008] Furthermore, the diameters of the first circular shaft and the second circular shaft are equal, and reserved circular holes are provided at the same position near the edge inside the first circular shaft and the second circular shaft. The upper and lower ends of the connecting rod pass through the reserved circular holes and are fixedly connected to the first circular shaft and the second circular shaft respectively. The first circular shaft and the second circular shaft can rotate synchronously, and a transmission rod is sleeved on the connecting rod.

[0009] The beneficial effect of adopting the above technical solution is that the design enables the first circular axis and the second circular axis to have the same angular velocity to ensure that the two axes remain synchronized during movement, thereby ensuring that the transmission rod can convert circular motion into linear reciprocating motion, making the overall system more stable during operation.

[0010] Furthermore, the transmission rod is composed of two middle straight rods and three smooth round shafts, and the three smooth round shafts are respectively fixedly connected to both ends of the two middle straight rods to form the transmission rod.

[0011] The beneficial effect of adopting the above technical solution is that: the functional requirement that the smooth round shaft part of the transmission rod can rotate is met, making the structure of the transmission rod more stable, and at the same time meeting the functional requirement of converting circular motion into linear reciprocating motion.

[0012] Furthermore, the cleaning device is a symmetrical structure along the cross-section of the pipeline, and a shaft rod and a crank are arranged on the front and rear sides of the second circular shaft. The smooth circular shaft in the middle of the transmission rod is sleeved on the connecting rod, and the smooth circular shafts on both sides are sleeved on the shaft rod, and the shaft rod and the smooth circular shaft are hingedly connected.

[0013] The beneficial effect of adopting the above technical solution is that the symmetrical structure design enables the inner wall of the pipeline in front and behind the second circular axis to be effectively cleaned, which greatly increases the cleaning range of the device and improves the cleaning efficiency.

[0014] Furthermore, the lower surface of the second circular shaft is evenly and equidistantly fixedly connected with bristles, which can clean the crystals located at the lower part thereof, and is fixedly connected to the bottom of the pipeline through a base.

[0015] The beneficial effect of adopting the above technical solution is that the inner wall of the pipeline located below the second circular axis can be effectively cleaned synchronously, thereby further increasing the cleaning range of the device.

[0016] Furthermore, the turbine blades can utilize the impact force of the water flow inside the pipeline to drive the first circular shaft to rotate. The rotation of the first circular shaft drives the second circular shaft to rotate through the connecting rod. The rotation of the second circular shaft drives the crank through the transmission rod to achieve automatic reciprocating linear motion. The device does not require other external forces such as electricity to drive it.

[0017] The beneficial effects of adopting the above technical solution are: the pipeline cleaning procedure is simple, no professional personnel are required for operation and maintenance, and the cleaning process will not cause corrosion, fatigue, breakage or other adverse effects on the internal materials of the pipeline; the device has high efficiency in the cleaning process, and at the same time has a simple structure and low manufacturing cost; at the same time, the device does not require external energy such as electricity to drive, so it saves costs during use; the design of the entire device is based on mechanical principles, and is driven by fluid pressure or mechanical movement in the pipeline, ensuring simple operation and high stability, and is suitable for various types of pipeline cleaning tasks.

[0018] Furthermore, the crank is composed of an intermediate shell and sliders at both ends. The side ends of the sliders are fixedly connected to the side ends of the intermediate shell. The slider includes a plurality of balls inside. The lower end of the slider is mounted on a slide rail. The intermediate shell is an arc-shaped structure. The lower surface of the bottom of the intermediate shell is evenly and equidistantly fixedly connected to the bristles.

[0019] The beneficial effects of adopting the above technical solution are: the crank adopts a separate design, and when the slider is irreparably damaged, only the slider needs to be replaced without replacing the entire crank; the slider includes a number of ball bearings inside to reduce the friction between the slider and the slide rail interface and reduce energy loss; the arc-shaped structure design of the intermediate shell is conducive to the structure to better fit the inner wall of the pipeline, thereby improving the pipeline cleaning effect.

[0020] Furthermore, the slide rail is fixedly mounted on the inner wall of the pipe by a plurality of screws, and reserved grooves are provided on both sides; and a sliding block is installed on the reserved groove.

[0021] The beneficial effect of adopting the above technical solution is that: the functional requirement of the slide rail being fixedly connected to the inner wall of the pipe is met, and the reserved groove is conducive to the sliding of the slider and the stability of the structure.

[0022] Furthermore, the length of the slide rail along the tube length direction is slightly greater than the diameter of the second circular axis, and the slide rail is symmetrically arranged along the tube length and tube diameter direction, and is arranged under each slider, and there are four slide rails in total.

[0023] The beneficial effect of adopting the above technical solution is that the use of four slide rails with a length greater than the diameter of the second circular shaft reduces the length of the slide rails while meeting the basic functional requirements of the sliding of the slider, which is conducive to cost saving.

[0024] The working principle and beneficial effects of the present invention are: The present invention includes a driving mechanism, a transmission mechanism and a cleaning mechanism, and is a symmetrical structure along the cross section of the pipeline. When liquid passes through the pipeline, the liquid impacts the turbine blades, and the turbine blades begin to generate circular motion, driving the first circular shaft fixedly connected to the inside of the turbine blades to start rotating, so that the first circular shaft and the second circular shaft fixedly connected by the connecting rod rotate synchronously, and the bristles located at the bottom of the second circular shaft begin to clean, and at the same time, the transmission rod sleeved on the connecting rod rotates around the sleeve point, thereby prompting the crank hinged on the transmission rod to generate synchronous linear reciprocating motion. The crank adopts a separate design, and the intermediate shell is designed in an arc-shaped structure, so that the bristles evenly arranged at the bottom of the crank simultaneously start to repeatedly clean the inner wall of the pipeline, thereby achieving the purpose of automatically cleaning crystals in the pipeline.

[0025] This method has the following advantages: the pipeline cleaning procedure is simple, the cost is low, the stability is high, the cleaning efficiency is high, and it is suitable for various types of pipeline cleaning tasks; the first circular axis and the second circular axis have the same angular velocity to ensure that the two axes remain synchronized during movement, thereby ensuring that the transmission rod can convert the circular motion into linear reciprocating motion, making the overall system more stable during operation; the symmetrical structure and the design of the bristles under the second circular axis enable the inner wall of the pipeline below the front and rear of the second circular axis to be effectively cleaned, greatly increasing the cleaning range of the device and improving the cleaning efficiency.
