Description

Technical Field

[0001] This utility model relates to the field of dredging equipment, and in particular to a reservoir dredging device. Background Technology

[0002] Traditional dredging methods in reservoirs mainly include manual labor or excavator operations, and grab bucket dredging. However, these traditional methods have various drawbacks in actual construction. First, manual labor or excavator operations require water release, which affects the reservoir's normal water storage and supply functions during construction, and also results in high construction costs and long construction periods. Second, grab bucket dredging is inconvenient to enter when facing independent water areas, limiting the water volume that can be used.

[0003] Existing technologies also include dredging methods that use pumping, but the pumping effect is unsatisfactory when the sludge at the bottom of the pool is viscous or unevenly distributed. Currently, there is a lack of corresponding solutions to these problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a reservoir dredging device that is simple to use, requires no drainage, has a good sludge removal effect, and is especially suitable for small reservoir dredging operations.

[0005] The equipment includes a reciprocating traction unit, a float plate, and a pumping unit; The reciprocating traction unit includes two pulleys, with a traction steel cable wound between the two pulleys, and each pulley is equipped with a power unit. The traction steel cable is connected to the float plate. The pumping unit includes a slurry pump and a sludge crushing structure; the slurry pump is fixedly mounted on a floating plate, and a power supply module is provided on the floating plate, the power supply module being poweredly connected to the slurry pump. The slurry pump inlet is connected to a sludge pumping pipeline, and its outlet is connected to a sludge conveying pipeline; a sludge crushing structure is installed below the float via a suspension steel cable.

[0006] The effect achieved is that the movement of a pulley in the reciprocating traction unit causes the float to move in the direction of the pulley. As the float moves, the sludge breaking structure at its bottom goes deeper into the sludge and loosens the viscous sludge. The sludge pumping pipe at the rear then pumps out the sludge to achieve the sludge removal action. By adjusting the position of the reciprocating traction unit, a comprehensive sludge removal operation can be achieved in the water body.

[0007] The beneficial effects of this utility model are: it solves the problem of inconvenient reservoir dredging in the prior art, and provides a dredging method based on the problem of viscous silt by pumping. The construction process does not affect the normal water storage and supply function of the reservoir, and the construction is convenient and can be carried out at any time. It is especially suitable for small reservoir dredging projects, and the equipment structure is simple with low cost and maintenance. Attached Figure Description

Detailed Implementation

[0009] Reference Figure 1 , Figure 2 The reservoir dredging device described in this utility model includes a reciprocating traction unit 1, a floating plate 2, and a pumping unit; The reciprocating traction unit 1 includes two pulleys 11, with a traction steel cable wound between the two pulleys 11, and each of the two pulleys 11 is equipped with a power unit; The traction steel cable is connected to the float 2. The pumping unit includes a slurry pump 3 and a sludge crushing structure 4; the slurry pump 3 is fixedly mounted on the floating plate 2, and the floating plate 2 is equipped with a power supply module, which is poweredly connected to the slurry pump 3. The slurry pump 3 is connected to the sludge pumping pipe 5 at its inlet and to the sludge conveying pipe at its outlet; a sludge crushing structure 4 is installed below the float 2 by means of a suspension steel cable.

[0010] The effect achieved is that when one of the reciprocating pullers 11 moves, the float 2 moves towards the puller 11. As the float 2 moves, the silt breaking structure 4 at its bottom goes deeper into the silt and loosens the viscous sludge. The silt pumping pipe 5 at the rear then pumps out the sludge to achieve the sludge removal action. By adjusting the position of the reciprocating puller 1, the sludge removal operation in the water body can be achieved.

[0011] In Example 1, the power unit includes a motor, a reducer, and a clutch mechanism; the motor is powered by the reducer, and the reducer is powered by the pulley 11 through the clutch mechanism.

[0012] This is achieved by enabling the gearbox to be equipped with a smaller motor, thereby ensuring stable stroke.

[0013] Furthermore, refer to the accompanying drawings in the instruction manual. Figure 3 The clutch mechanism is configured in the following form: The reel 11 is fixedly connected to the drive shaft 111, and the output end of the reducer is fixedly connected to the drive shaft 113 via a coupling. Both the drive shaft 113 and the drive shaft 111 are splined shafts. A spline sleeve 112 is slidably arranged between the drive shaft 113 and the drive shaft 111, and a position locking component is also provided between the spline sleeve 112 and the drive shaft 113 and the drive shaft 111.

[0014] Preferably, the position locking component is a hard limit bolt.

[0015] The effect achieved is that the power transmission can be quickly engaged or disengaged through the displacement of the spline sleeve 112. That is, when a single power unit moves, its opposite power unit stops moving and the transmission is separated through the displacement of the spline sleeve 112, thus avoiding mechanical self-locking and motion interference.

[0016] In embodiment 2, a support plate 12 is fixedly connected to the bottom of the spool 11, and a traveling wheel 13 is also provided under the support plate 12. At least three traveling wheels 13 are provided, and the direction of the traveling wheels 13 is perpendicular to the winding and unwinding direction of the spool 11. Anchor holes are also provided on the support plate 12, and anchor rods 14 are inserted into the anchor holes.

[0017] The effect achieved is to ensure the stability of the position of the reciprocating traction unit 1 during equipment operation.

[0018] In Example 3, the floating plate 2 is provided with a water-blocking side plate.

[0019] This achieves the effect of preventing water from entering the float plate 2.

[0020] Example 4: The power supply module is one of a gasoline engine, an oil pumping machine, or an electric motor. When the power supply module is an electric motor, a waterproof power supply is integrated on the float 2 and the motor is a waterproof motor.

[0021] The effect achieved in this way is to ensure the safe operation of the equipment.

[0022] Example 5, refer to the accompanying drawings in the specification. Figure 1 The slurry pump 3 is centrally located on top of the float 2, and the suspension cable is centrally located on the bottom surface of the float 2; thus, the float 2 operates stably. The sludge pumping pipe 5 is equipped with a hoop at the front, and the hoop is connected to the sludge crushing structure 4 by rope tension.

[0023] The effect achieved is that the pipe opening of the sludge pumping pipe 5 is always close to the sludge crushing structure 4, thereby enabling immediate pumping of the sludge after crushing.

[0024] In Example 6, the width of the sludge crushing structure 4 is greater than the opening of the sludge pumping pipe 5, and its thickness is no more than one-third of the sludge pumping pipe 5.

[0025] Preferably, the sludge crushing structure 4 includes a centrally located assembly ring, and the outer surface of the assembly ring is uniformly arrayed with multiple disturbance spikes.

[0026] This achieves the effect of preventing the heavy ball from clogging the pipe opening and affecting the pumping effect.
