Description

Technical Field

[0001] This utility model relates to the field of waterway dredging simulation technology, specifically a waterway dredging simulation device. Background Technology

[0002] Portable channel dredging simulation test device is a device that uses model technology to simulate a silted channel on a test device to conduct channel dredging tests, thereby deriving targeted and efficient dredging solutions. This avoids prolonging the construction period by testing various dredging solutions during actual construction and improves the efficiency of channel dredging.

[0003] In the prior art, Chinese utility model application number CN202222778912.4 discloses a portable channel dredging simulation test device, including a shock-absorbing spring base, a frame, and a bearing shaft. Wheels are mounted on the lower surface of the shock-absorbing spring base. A motor is installed at one end of the frame, and the output end of the motor is connected to a chain via a gear disc. A compound gear is engaged with one side of the chain via gear meshing. A slider is connected to the surface of a sliding rod, and a simulation device box is connected to one side of the slider via a support. A slurry pump is connected to a suction head via a slurry pipe. A robotic arm is mounted above the slide, and the robotic arm is connected to a grab bucket via a steel-like hinge rope. This portable channel dredging simulation test device is equipped with a shock-absorbing spring base and wheels, allowing for convenient movement of the device. Simultaneously, the shock-absorbing effect of the spring base protects the simulation device box inside the frame, preventing damage during movement.

[0004] While the above-mentioned technical solution utilizes a base and wheels to facilitate the transfer of the simulation device and improve convenience, the wheels are not fixed during the channel dredging simulation test, which may cause the entire frame to shake. The device may shake, affecting the water flow and thus the accuracy of the channel dredging simulation test results. Therefore, we need to propose a channel dredging simulation device.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model mainly improves the stability of the simulation device body during waterway dredging simulation tests by coordinating the protective box, drive mechanism, simulation device body, transmission mechanism, and support mechanism.

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 1-3 This utility model provides a technical solution: a channel dredging simulation device, including a protective box 1, a simulation device body 4 is provided in the inner cavity of the protective box 1, a drive mechanism 3 for lifting and lowering the simulation device body 4 is provided on one side of the inner cavity of the protective box 1, two sets of transmission mechanisms 5 driven by the drive mechanism 3 are provided at the bottom of the inner cavity of the protective box 1, and a support mechanism 6 driven by the two sets of transmission mechanisms 5 is provided below the protective box 1.

[0024] The drive mechanism 3 includes a motor 31, the output shaft of the motor 31 is connected to a rotating shaft 32, and both ends of the rotating shaft 32 are provided with first bevel gears 33;

[0025] The transmission mechanism 5 includes two sets of bearing seats 51 and a transmission shaft 52 rotatably disposed between the two sets of bearing seats 51. Both ends of the transmission shaft 52 are provided with second bevel gears 53, one of which meshes with the first bevel gear 33.

[0026] The support mechanism 6 includes a vertical shaft 61 rotatably mounted on the lower surface of the protective box 1. The upper end of the vertical shaft 61 is located in the inner cavity of the protective box 1 and is fixedly connected to a third bevel gear 62 that meshes with the second bevel gear 53. The lower end of the vertical shaft 61 has an external thread on its outer side. The lower end of the vertical shaft 61 is threadedly connected to a threaded sleeve 63. The lower end of the threaded sleeve 63 is fixedly connected to a support base plate 64.

[0027] The support base plate 64 is arranged in a cross shape. Multiple sets of telescopic rods 65 are fixedly connected to the upper surface of the support base plate 64. The upper ends of the multiple sets of telescopic rods 65 are all fixedly connected to the lower surface of the protective box 1. The lower surface of the support base plate 64 is provided with anti-slip pads, which improves the stability of the support protective box 1.

[0028] The lower surface of the protective box 1 is provided with multiple sets of shock-absorbing moving wheels 7. The height of the multiple sets of shock-absorbing moving wheels 7 is greater than the height of the threaded sleeve. The multiple sets of shock-absorbing moving wheels 7 facilitate the rapid movement of the protective box 1, thereby improving the convenience of the mobile simulation device body 4.

[0029] The drive mechanism 3 also includes a connecting shaft 36 rotatably disposed inside the protective box 1. A second sprocket 37 is disposed in the middle of the connecting shaft 36, and a first sprocket 34 is disposed in the middle of the rotating shaft 32. A synchronous chain 35 is disposed between the first sprocket 34 and the second sprocket 37. Two sets of toothed plates 41 are disposed on one side of the simulation device body 4. Both ends of the connecting shaft 36 are provided with compound gears 38 that mesh with the toothed plates 41. The first sprocket 34 and the first bevel gear 33 are synchronously driven by the rotating shaft 32, so as to facilitate the lifting of the simulation device body 4 and the unfolding of the support mechanism 6, thereby facilitating the maintenance of the stability of the device during teaching.

[0030] A guide plate 42 is fixedly connected to the bottom of the simulation device. Multiple sets of guide rods 8 are fixedly connected to the inner cavity of the protective box 1 for sliding of the guide plate 42. The lower ends of the multiple sets of guide rods 8 are fixedly connected to limit seats 81. The guide plate 42 is provided with sliding holes for sliding of the multiple sets of guide rods 8, which improves the stability of the simulation device body 4 in raising and lowering. The limit seats 81 support the simulation device body 4, preventing the simulation device body 4 from contacting the vertical shaft 61 and improving the overall service life of the device.

[0031] A cover 2 is rotatably mounted on one end of the upper surface of the protective box 1. The opening of the protective box 1 is larger than the cross-section of the simulation device. The cover 2 can protect the simulation device body 4 when it is transported, thereby improving its service life.

[0032] The simulation device body 4 includes a box, a slide, a robotic arm, a mud pump, and a grab bucket. The box is transparent, and the robotic arm is installed on the slide. The simulation device body 4 can simulate the process of waterway dredging, which is convenient for teaching and improves its practicality. At the same time, it is easy to store in the protective box 1, which improves its service life.

[0033] In use, the entire device is moved to the designated location by the shock-absorbing moving wheels 7 under the protective box 1. When conducting channel dredging simulation, the box cover 2 is opened and the motor 31 is started. The motor 31 drives the rotating shaft 32 to rotate the first sprocket 34 and the first bevel gear 33. The first sprocket 34 rotates the second sprocket 37 on the connecting shaft 36 through the synchronous chain 35, thereby causing the compound gear 38 to drive the toothed plate 41. The simulation device body 4 located inside the box is raised along the guide rod 8, which facilitates the removal of the simulation device from the protective box 1 and makes it easier to observe during channel dredging simulation. At the same time, the first bevel gear 33 meshes with the second bevel gear 53 at one end of the transmission shaft 52, thereby causing the second bevel gear 53 at the other end of the transmission shaft 52 to mesh with the third bevel gear 62 on the vertical shaft 61, causing the vertical shaft 61 to drive the screw sleeve 63 to descend. Under the restraint of multiple sets of telescopic rods 65, the supporting base plate 64 touches the ground while the shock-absorbing moving wheels 7 are lifted off the ground, thereby improving the stability of the simulation device body 4 during channel dredging simulation and improving the accuracy of the channel dredging simulation test results.
