Description

Technical Field

[0001] This utility model relates to the field of water conservancy dredging technology, and in particular to a floating pontoon type riverbed dredging device. Background Technology

[0002] With the continuous acceleration of urbanization and the increasing demands of people for the quality of the aquatic ecological environment, the problem of silt accumulation at the bottom of rivers, lakes, reservoirs, and artificial waterways is becoming increasingly serious. Long-term sediment deposition not only significantly reduces the cross-sectional area and water storage capacity of river channels, affecting flood control and drainage functions, but may also become a secondary source of pollutants, leading to water quality deterioration, mosquito breeding, and disruption of the aquatic ecosystem balance. Therefore, regular riverbed dredging is of great significance for ensuring the safe operation of water conservancy facilities and improving the quality of the aquatic environment.

[0003] Patent CN206851786U discloses a high-efficiency fishpond dredging device. The device includes a propeller, a transmission rod, a dredging pump, a dredging connector, a one-way valve, floats, a transmission cylinder, a motor, a handle, a support frame, and a fixing ring. Two floats are connected in the middle by the support frame, and their tops are fastened to the right end of the support frame by the fixing ring. The handle is welded to the middle of the right end of the support frame. The transmission cylinder is welded through and to the top of the right end of the support frame, with the motor locked to the right end and the dredging pump locked to the left end. The transmission rod is fastened through and to the left end of the dredging pump, and the dredging connector is locked to its top. A fixing ring is welded to the left end of the transmission rod. The device features three propellers and a one-way valve bonded to the right end of the sludge discharge connector. A motor drives a transmission cylinder, which in turn drives the sludge pump and transmission rod. The pump draws in sludge, which is then discharged through the sludge discharge connector by opening a spring-loaded baffle on the one-way valve. When the pump stops, the valve automatically closes to prevent backflow of sludge, thus improving the safety and convenience of the equipment. However, some shortcomings remain in practical applications. The device lacks effective adjustment components, making it impossible to flexibly adjust the working position of the sludge removal components according to different water depths and riverbed topography, thus limiting sludge removal efficiency.

[0004] Therefore, there is an urgent need to provide a floating riverbed dredging device that can flexibly adjust its working height according to different water depths and terrain conditions. Utility Model Content

[0005] In order to overcome the shortcomings of existing dredging devices that lack effective height adjustment function and cannot flexibly adjust the working position of the dredging components according to different water depth conditions and riverbed topography, resulting in limited dredging efficiency, this utility model provides a floating riverbed dredging device that can flexibly adjust the working height according to different water depth and topography conditions.

[0006] To address the aforementioned problems, this utility model adopts the following technical solution: a floating pontoon-type riverbed dredging device, comprising a floating pontoon, an installation pontoon, a support base, a waterproof motor, a connecting rod, a collection box, a suction wheel, a discharge pipe, and an adjustment assembly. The floating pontoons are of two symmetrical arrangement. An installation pontoon is connected between the two floating pontoons via the adjustment assembly. A support base is provided at the bottom of the installation pontoon. A waterproof motor is installed at one end of the installation pontoon, with its output shaft extending into the installation pontoon and connected to a connecting rod at its end. A collection box is provided at the other end of the installation pontoon, and a suction wheel is installed inside the collection box. The suction wheel is fixedly connected to the connecting rod. A mud discharge pipe is provided on the top of the collection box, and the mud discharge pipe communicates with the inside of the collection box. The adjustment assembly consists of a mounting frame, a guide rod, a screw, and a U-shaped handle. Each floating cylinder is provided with two symmetrically distributed mounting frames. The tops of two adjacent mounting frames are jointly provided with a U-shaped handle. Three of the mounting frames are fixedly connected with vertically arranged guide rods, which pass through the support base and form a sliding connection with it. The remaining mounting frame is rotatably provided with a vertically arranged screw, which passes through the support base and forms a threaded connection with it.

[0007] To further explain, the mounting cylinder is arranged at an angle, with the top higher than the bottom.

[0008] To further explain, the end of the mud outlet pipe adopts a retractable flexible hose structure.

[0009] To further explain, it also includes a fixing plate, a first screw, and a stirring rod. The suction wheel is provided with multiple fixing plates evenly spaced along its circumference. Each fixing plate is fastened to the outer edge of the suction wheel by a first screw and is radially distributed. A stirring rod is fixedly connected to each fixing plate.

[0010] To further explain, it also includes cutting blades, with each of the agitator bars having a cutting blade.

[0011] To further explain, it also includes a locator and a second screw, with the locator fixedly mounted on the mounting cylinder by the second screw.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By setting an adjustment component that combines guide rod and screw, the working position of the suction wheel can be conveniently and quickly adjusted according to different water depth conditions and riverbed topography. This design not only improves the adaptability of the equipment to different working environments, but also effectively improves the dredging efficiency.

[0013] 2. The suction wheel is equipped with a stirring rod and a cutting blade. During rotation, it can not only effectively stir the sludge, improve its fluidity, and facilitate rapid suction, but also cut debris in the sludge to prevent foreign objects from clogging the suction wheel and ensure the continuous and stable operation of the equipment.

Detailed Implementation

[0021] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0022] Example 1: Please refer to Figures 1-4A floating dredging device for riverbeds includes a floating cylinder 1, an installation cylinder 2, a support base 201, a waterproof motor 3, a connecting rod 4, a collection box 5, a suction wheel 6, a discharge pipe 7, and an adjustment assembly. Two floating cylinders 1 are arranged symmetrically to provide stable buoyancy support for the entire device. An installation cylinder 2 is connected between the two floating cylinders 1 via the adjustment assembly. The installation cylinder 2 is inclined at the top and lower at the bottom, which facilitates effective dredging by keeping its lower end close to the riverbed, and also allows for elevation adjustments. The waterproof motor 3 is positioned to reduce the risk of water ingress. A support base 201 is provided at the bottom of the mounting cylinder 2. The waterproof motor 3 is mounted at one end of the mounting cylinder 2, and its output shaft extends into the mounting cylinder 2, with a connecting rod 4 connected to its end. A collection box 5 is provided at the other end of the mounting cylinder 2. A suction wheel 6 is installed inside the collection box 5, and the suction wheel 6 is fixedly connected to the connecting rod 4. The waterproof motor 3 can drive the suction wheel 6 to rotate and suck the silt from the riverbed into the collection box 5. The top of the collection box 5... A mud discharge pipe 7 is provided, which is connected to the inside of the collection box 5, for transporting the sucked-in sludge to the shore or transport equipment. In addition, the end of the mud discharge pipe 7 adopts a telescopic hose structure to adapt to the needs of different sludge discharge positions and working heights. The adjustment component consists of a mounting frame 8, a guide rod 802, a screw 803, and a U-shaped handle. Each floating cylinder 1 is provided with two mounting frames 8 symmetrically distributed front and rear. The tops of two adjacent mounting frames 8 are jointly provided with a U-shaped handle for easy operation and movement by the operator. The device includes three mounting brackets 8 with vertically arranged guide rods 802 fixedly connected to them. The guide rods 802 pass through the support base 201 and are slidably connected thereto. The remaining mounting bracket 8 has a vertically arranged screw 803 rotatably arranged on it. The screw 803 passes through the support base 201 and is threaded thereto. By rotating the screw 803, the entire mounting cylinder 2 can be driven to move up and down along the guide rod 802, thereby adjusting the working height of the sludge suction assembly to adapt to different water depths and riverbed topography changes.

[0023] Please see Figure 6 It also includes a locator 13 and a second screw 14. The locator 13 is fixedly installed on the mounting cylinder 2 by the second screw 14. It is used to accurately locate the working position of the dredging device and helps the operator to monitor the specific coordinates and movement trajectory of the equipment in the water in real time.

[0024] When in use, the device provides sufficient buoyancy through two floating cylinders 1, allowing it to float stably on the water surface. Then, the operator manually rotates the screw 803 according to the actual water depth and riverbed topography. Since the screw 803 is threadedly connected to the support base 201, and the other three points are slidably connected to the support base 201 through the guide rod 802, rotating the screw 803 can drive the entire mounting cylinder 2 to move up and down along the guide rod 802, thereby adjusting the height of the suction wheel 6 from the riverbed to adapt to different water depths and topographical conditions, ensuring maximum dredging efficiency. After the height adjustment is completed, the waterproof motor 3 is started. The waterproof motor 3 drives the suction wheel 6 to rotate at high speed through the connecting rod 4, generating a negative pressure effect, thereby sucking the silt from the riverbed into the collection box 5. Finally, the silt in the collection box 5 is discharged through the mud outlet pipe 7 at the top and transported to a designated location, such as a riverbank collection pool or a transport vehicle, completing the dredging operation.

[0025] Example 2: Based on Example 1, please refer to... Figure 5 It also includes a fixing plate 9, a first screw 10, a stirring rod 11, and a cutting blade 12. The suction wheel 6 is evenly spaced with five fixing plates 9 along its circumference. Each fixing plate 9 is fastened to the outer edge of the suction wheel 6 by the first screw 10 and is radially distributed. Each fixing plate 9 is fixedly connected with a stirring rod 11 to enhance the disturbance ability of water flow and silt. Each stirring rod 11 is equipped with a cutting blade 12 for cutting debris, aquatic plants, plastic waste and other foreign objects during the suction process.

[0026] During the dredging operation, the waterproof motor 3 drives the suction wheel 6 to rotate at high speed. The suction wheel 6 drives the fixed plate 9 and the stirring rod 11 on it to rotate synchronously. At this time, the stirring rod 11 stirs the silt at the bottom of the riverbed during rotation, so that the originally dense silt is loosened and mixed with the water, thereby improving the fluidity of the silt. This helps the suction wheel 6 to suck the silt into the collection box 5 more efficiently, avoiding the phenomenon of poor suction or even blockage caused by the silt being sticky or clumpy. At the same time, the cutting blade 12 set on the stirring rod 11 can perform preliminary crushing of the silt entering the suction chamber during the suction process. Especially when the silt contains large particles such as branches, water plants, and plastic bags, the cutting blade 12 can effectively cut or crush them, preventing these foreign objects from getting entangled or stuck inside the suction wheel 6, thereby improving the operational stability and continuous operation capability of the entire dredging system.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
