Description

Technical Field

[0001] This utility model relates to the field of pipeline protection technology, specifically a pipeline protection device for dredging equipment in water conservancy projects. Background Technology

[0002] Utility model patent application CN207295820U discloses a dredging device for water conservancy projects, including a water pump. The water pump is connected to a water pump pipeline via a third clamp. A monitor cover is installed on the outside of the monitor. The water pump outlet is equipped with a water pump inlet cover, which has a mesh structure. A barrier net is installed on the outside of the water pump inlet cover. Motor covers are installed on both sides of the water pump, and a motor is installed inside the motor covers. A mud pump is installed on the outside of the motor covers.

[0003] The inlet of the mud pump is connected to the inlet pipe via a second clamp.

[0004] The advantages are: the use of modern electronic technology and the use of electric motors enable the dredging equipment to move and work underwater with seamless tracks. The addition of wire mesh protective structures at the slurry inlet and pump inlet can effectively prevent large particles of debris in the sludge from entering the pump and causing significant damage to the pump. It also prevents the equipment from stopping or experiencing abnormal operating conditions due to the ingestion of large particles of debris, thus extending the equipment's lifespan.

[0005] In the prior art including the aforementioned patents, the use of dredging equipment in water conservancy projects is prone to clogging after prolonged use due to the large amount of impurities in the silt. Since the inside of the equipment's pipes is difficult to clean, filter screens are generally used to protect and block impurities. However, this increases the risk of pipe blockage. Furthermore, if the inside of the pipes is not cleaned for a long time, it can easily lead to equipment problems and affect the operation of the equipment. Utility Model Content

[0006] The purpose of this utility model is to provide a pipeline protection device for dredging equipment in water conservancy projects, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pipeline protection device for a water conservancy project dredging equipment, comprising a housing, a motor installed on the inner wall of the housing, a rotating rod installed on the output end of the motor via a coupling, a turntable installed on the outer wall of the rotating rod via a coupling, a first connecting rod movably installed on the outer wall of the turntable, a second connecting rod movably connected to one end of the first connecting rod, a connecting rod installed on the outer wall of the first connecting rod, a roller installed on one end of the second connecting rod, and an adjusting rod movably installed on the inner wall of one end of the first connecting rod.

[0008] Furthermore, a connecting plate is mounted on one side of the turntable via a coupling, and an installation rod is provided on the outer wall of the connecting plate, with a brush head provided at one end of the installation rod.

[0009] Furthermore, a scraper is installed on the outer wall of the brush head, and a camera is movably installed at one end of the rotating rod.

[0010] Furthermore, one end of the first link and one end of the second link are connected by an adjusting rod, and the first link and the second link form a transmission connection through the adjusting rod.

[0011] Furthermore, a roller is installed at one end of the second connecting rod, and the roller is installed at an angle.

[0012] Furthermore, each of the brush heads is provided with a scraper blade on its outer wall, and the scraper blade is installed at an angle.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the pipeline protection device of this water conservancy engineering dredging equipment is reasonable and has the following advantages:

[0014] (1) This utility can be adjusted according to the diameter of different pipes. By rotating the adjustment rod and taking it out, rotate the second connecting rod until the roller is close to the inner wall of the pipe, and then reinsert the adjustment rod. This makes the equipment adaptable to pipes of various diameters, with strong versatility and flexibility. At the same time, only one motor is needed to control the equipment to move forward in the pipe. While this utility is moving forward, the brush head and scraper can be controlled by the motor to clean the inner wall of the pipe, thereby ensuring the cleanliness of the inside of the pipe and preventing equipment failure caused by pipe blockage due to the accumulation of impurities in the pipe. In addition, this utility has a simple structure, which not only reduces costs but also improves work efficiency. Users can also observe the situation inside the pipe through the camera.

[0015] (2) This utility model uses a motor to drive the rotation of the brush head and scraper, so that the equipment can move in the pipe and perform effective cleaning work in the pipe. The inclined installation of the rollers allows them to stick to the inner wall of the pipe when rotating, providing forward power while removing debris and dirt in the pipe through the brush head and scraper. The brush head can brush away loose debris in the pipe, while the scraper can scrape away stubborn dirt attached to the inner wall of the pipe, so that the deposits can be washed away by the water flow after being scraped off. This can prevent impurities and dirt in the pipe from corroding the inner wall of the pipe, causing the pipe to age and crack, thereby improving the cleaning performance of the equipment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 The technical solution provided by this utility model is as follows:

[0024] Example 1:

[0025] In this embodiment, a pipeline protection device for a water conservancy engineering dredging equipment includes a housing 1. A motor 2 is installed on the inner wall of the housing 1. A rotating rod 3 is installed on the output end of the motor 2 via a coupling. A turntable 4 is installed on the outer wall of the rotating rod 3 via a coupling. A first connecting rod 5 is movably installed on the outer wall of the turntable 4. A second connecting rod 6 is movably connected to one end of the first connecting rod 5. A connecting rod 9 is installed on the outer wall of the first connecting rod 5. A roller 7 is installed on one end of the second connecting rod 6. An adjusting rod 8 is movably installed on the inner wall of one end of the first connecting rod 5.

[0026] In this embodiment, a connecting plate 10 is installed on one side of the turntable 4 via a coupling. An installation rod 11 is provided on the outer wall of the connecting plate 10. A brush head 12 is provided at one end of the installation rod 11. When the turntable 3 rotates, it will drive the installation rod 11 to rotate synchronously. When the installation rod 11 rotates, it will drive the brush head 12 to rotate synchronously.

[0027] In this embodiment, a scraper 13 is installed on the outer wall of the brush head 12, and a camera 14 is movably installed at one end of the rotating rod 3. When the connecting plate 10 rotates, it will drive the mounting rod 11 to rotate. When the mounting rod 11 rotates, the brush head 12 at one end can brush away the debris in the pipe. Then, the scraper 13 installed on the outer wall of the brush head 12 will rotate synchronously when the brush head 12 rotates. When the scraper 13 rotates, it can scrape away some dirt on the inner wall of the pipe.

[0028] In this embodiment, one end of the first link 5 and the second link 6 are connected by an adjusting rod 8. The first link 5 and the second link 6 are connected by the adjusting rod 8. The user can adjust the angle of the second link 6 by pulling out the adjusting rod 8. By adjusting the angle of the second link 6, the following can be achieved.

[0029] In this embodiment, a roller 7 is installed at one end of the second connecting rod 6. The roller 7 is installed at an angle. Because the roller 7 is installed at an angle, it will stick to the inner wall of the pipe when it rotates and provide the device with the power to move forward in the pipe.

[0030] In this embodiment, the outer wall of the brush head 12 is provided with scraper blades 13. The scraper blades 13 are installed at an angle. The brush head 12 can brush away debris in the pipe, while the scraper blades 13 on the outer wall of the brush head 12 can scrape away some dirt on the inner wall of the pipe.

[0031] Working principle: In use, the user can first adjust the force position of the device according to the diameter of different pipes. The specific adjustment method is that the user can rotate the adjusting rod 8, then remove the adjusting rod 8 and rotate the second connecting rod 6 until the roller 7 set at one end of the second connecting rod 6 can be tightly attached to the inner wall of the pipe. Then, rotate the adjusting rod 8 back in. After that, the user starts the motor 2. After the motor 2 starts, it will drive the rotating rod 3 to rotate. When the rotating rod 3 rotates, it will drive the turntable 4 to rotate. When the turntable 4 rotates, it will drive the first connecting rod 5 to rotate. The first connecting rod 5 will drive the roller 7 to rotate through the second connecting rod 6. At this time, the roller 7 will rotate in a circular motion. Since the roller 7 is installed at an angle, the roller 7 will be close to the inner wall of the pipe when it rotates, providing the device with the power to move forward in the pipe.

[0032] Finally, as the rotating rod 3 rotates, it also drives the connecting plate 10 to rotate. When the connecting plate 10 rotates, it drives the mounting rod 11 to rotate. When the mounting rod 11 rotates, the brush head 12 at one end will touch some debris in the pipe, such as algae. The brush head 12 can brush away the debris in the pipe. Then, the scraper 13 set on the outer wall of the brush head 12 will rotate synchronously when the brush head 12 rotates. When the scraper 13 rotates, it can scrape away some dirt on the inner wall of the pipe. After the scraped-off sediment is scraped off, the user can use water flow to flush it away. The user can observe the pipe in real time through the camera 14. At this point, the practical work is completed.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
