Description

Technical Field

[0001] The utility model relates to dredging equipment, in particular to dredging equipment used for waterways. Background Art

[0002] In water conservancy projects, waterways are passages for ships in inland waters such as rivers and lakes. They are also important links connecting various water conservancy project facilities, transporting materials and personnel. During long-term use, dredging equipment will be used to clean the silt inside the waterway to ensure that ships can operate well.

[0003] Basic dredging equipment is generally fixedly installed on a dredging vessel, and the silt is pumped out and placed inside the vessel. For silt of different depths in the waterway, the equipment is often unable to perform elastic silt breaking treatment. The equipment is directly nailed into the silt, which can easily extract larger impurities in the silt and cause blockage. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a dredging device for a waterway, which can penetrate into the silt in the waterway and improve the dredging effect.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A dredging device for a waterway comprises a transmission cylinder, a rotating rod is installed in the transmission cylinder, the upper end of the rotating rod is driven by a reduction motor, and the lower end is fixedly connected to a mounting rod, wherein a displacement groove is provided in the mounting rod; a displacement processing mechanism is installed at the bottom of the transmission cylinder, the displacement processing mechanism comprises a mounting sleeve, the upper end of the mounting sleeve is elastically connected to the transmission cylinder, a second spiral blade is provided in the mounting sleeve, a displacement rod is fixed to the upper end of the second spiral blade, the displacement rod slides up and down in cooperation with the displacement groove and rotates circumferentially with the mounting rod.

[0007] A plurality of connecting rods are circumferentially installed on the top end of the mounting sleeve, and the connecting rods are located in the auxiliary groove formed by the transmission cylinder and the receiving plate.

[0008] The connecting rod is connected to the inner wall of the auxiliary groove through a spring.

[0009] The displacement groove limits the circumferential rotation of the displacement rod relative to the installation rod, and the displacement groove does not limit the axial movement of the displacement rod relative to the installation rod.

[0010] At least one set of waterproof motors is fixed outside the installation sleeve, and the output end of the waterproof motor is connected to the crushing rod through an auxiliary shaft.

[0011] One side of the upper portion of the transmission cylinder is connected to a sewage pipe.

[0012] The output end of the sewage pipe is arranged to be inclined downward.

[0013] A fixing frame is fixed on the sewage pipe, and a positioning hole is opened at the lower end of the fixing frame.

[0014] The utility model provides a dredging device for waterways, which has the following technical effects:

[0015] 1) By setting up a displacement processing mechanism, the transmission cylinder and the installation sleeve can be inserted into the silt in the waterway. Under the elastic support of the spring, for thicker silt layers, the second spiral blade directly contacts the silt. When the reduction motor is controlled to work, the second spiral blade transports and lifts the silt and impurities. Under the action of the rotating first spiral blade, the lighter silt mixed with water is continuously transported upward, achieving the purpose of preventing blockage and desilting.

[0016] 2) By setting up a crushing rod, thicker silt layers can be squeezed and crushed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] like Figure 1 As shown, a dredging device for waterways includes a transmission drum 1, a reduction motor 2 being bolted to the top of the transmission drum 1. A rotating rod 8 is fixedly connected to the output end of the reduction motor 2, located within the inner cavity of the transmission drum 1. The other end of the rotating rod 8 is fixedly connected to a mounting rod 10. First spiral blades 7 are fixedly sleeved on the surfaces of the rotating rod 8 and the mounting rod 10. A sewage pipe 4 is connected to the top of the right side of the inner cavity of the transmission drum 1. A receiving plate 11 is fixedly connected to the bottom of the outer ring of the transmission drum 1. A displacement processing mechanism 6 is installed at the bottom of the transmission drum 1.

[0024] The displacement processing mechanism 6 includes a displacement rod 602 and a connecting rod 603. The bottom of the connecting rod 603 is fixedly connected to a mounting sleeve 604. The lower end of the displacement rod 602 is located in the inner cavity of the mounting sleeve 604 and is fixed with a second spiral blade 605. By arranging the second spiral blade 605 and the first spiral blade 7, silt and water can be transported upward in a rotating state. Waterproof motors 606 are fixedly installed on both sides of the mounting sleeve 604.

[0025] like Figure 2-3 As shown, an auxiliary groove 12 is provided inside the storage plate 11 for use with the connecting rod 603, and a displacement groove 9 is provided at one end of the mounting rod 10 for use with the displacement rod 602. By setting the displacement groove 9 and the auxiliary groove 12, the storage space requirements for the displacement rod 602 and the connecting rod 603 can be met respectively.

[0026] like Figure 2-3 As shown, the connection between the connecting rod 603 and the auxiliary groove 12, and the connection between the displacement rod 602 and the installation rod 10 are in sliding contact and sealed. By setting the connecting rod 603, the displacement of the installation sleeve 604 can be guided to ensure the stability of the installation sleeve 604.

[0027] like Figure 2-3 As shown, a spring 601 is installed on the surface of the connecting rod 603 and in the inner cavity of the auxiliary groove 12. One end of the spring 601 is fixedly connected to the inner wall of the auxiliary groove 12, and the other end of the spring 601 is fixedly connected to the surface of the connecting rod 603. By setting the spring 601, the connecting rod 603 can be elastically supported to maintain the connecting rod 603 in an extended state in the absence of external force.

[0028] like Figure 2-3 As shown, the top of the right side of the transmission cylinder 1 is fixedly connected with a fixing frame 3, and a positioning hole 5 is opened through the top of the fixing frame 3. By setting the fixing frame 3 and the positioning hole 5, the transmission cylinder 1 can be fixedly installed at a suitable position on the dredging ship with the cooperation of bolts, and the installation requirement of the sewage pipe 4 is met, thereby improving the overall stability of the equipment.

[0029] like Figure 2-3 As shown, the outer ring of the sewage pipe 4 is fixedly connected to the connection of the fixing frame 3, and the sewage pipe 4 is arranged to be inclined downward.

[0030] like Figure 2-3 As shown, the output end of the waterproof motor 606 is fixedly connected to an auxiliary shaft 607, and a crushing rod 608 is fixedly sleeved on the surface of the auxiliary shaft 607. By setting the auxiliary shaft 607 and the crushing rod 608, the crushing rod 608 can squeeze and crush thick silt layers under the drive of the waterproof motor 606.

[0031] like Figure 2-3As shown, the top of the inner cavity of the mounting sleeve 604 is fixedly connected to an auxiliary frame; the surface of the displacement rod 602 and the inner cavity of the displacement groove 9 are rectangular in design, which is used to make the rotating rod 8, the mounting rod 10 and the displacement rod 602 rotate synchronously under the drive of the reduction motor 2. The surface of the displacement rod 602 and the inner cavity of the mounting sleeve 604 are cylindrical, which not only meets the fixed installation requirements of the second spiral blade 605, but also can be movably connected to the auxiliary frame through a sealed bearing, so that the displacement rod 602 moves up and down together with the mounting sleeve 604.

[0032] In actual application, due to the complex water environment in the waterway, in order to improve the waterproof level of the waterproof motor 606 and prevent the waterproof motor 606 from being corroded and contaminated, a waterproof shell is fixedly installed on the surface of the mounting sleeve 604 and outside the waterproof motor 606.

[0033] Working principle and process:

[0034] 1) Before use, the silt layer in the waterway is cleared to prevent plastic impurities from entanglement and blockage between the second spiral blade 605 and the first spiral blade 7. During use, all components are in their initial installation state, with the mounting sleeve 604 and transmission cylinder 1 sunk into the waterway. Supported by the spring 601, the connecting rod 603 is extended and inserted into the silt layer via the mounting sleeve 604.

[0035] 2) Then, the reduction motor 2 is controlled to operate, driving the rotating rod 8 to rotate. With the cooperation of the displacement slot 9, the mounting rod 10, and the displacement rod 602, the first spiral blade 7 and the second spiral blade 605 rotate synchronously. The rotation of the second spiral blade 605, located in the silt layer, will simultaneously transport larger rocks and impurities up and down along with the silt. Since the rocks and impurities are heavier, they will fall quickly. The operation of the first spiral blade 7 absorbs and transports the raised silt impurities, which are ultimately discharged through the sewage pipe 4.

[0036] 3) As the silt layer is cleaned, the second spiral blade 605 can still keep in good contact with the silt layer under the elastic support of the spring 601, thereby ensuring cleaning efficiency. In actual use, for thicker silt layers, the waterproof motor 606 can be synchronously controlled to drive the auxiliary shaft 607 and the crushing rod 608 to rotate and perform auxiliary crushing of the silt layer, which is beneficial to subsequent silt clearing operations.
