Description

TECHNICAL FIELD

[0001] The present application relates to the dredging technical field, specifically relates to a dredging equipment for water conservancy construction. BACKGROUND

[0002] Dredging refers to the process of removing silt or sediment from the bottom of a water body. This process is important for maintaining the cleanliness of water bodies, preventing water pollution, improving water storage capacity, and maintaining the health of aquatic ecosystems. Dredging is often required during water conservancy construction. Common dredging equipment includes dredging ships and other facilities. There are many types of dredging machines, each with its own specific application and advantages. Common types include chain bucket dredgers, cutter suction dredgers, drag suction dredgers, and grab dredgers.

[0003] In the prior art, such as the Chinese patent with publication number CN209144901U, titled "Silt suction pump for river dredging", the technical solution is described as follows: a pump body, a silt suction port, and a silt discharge port are provided. A filter screen is installed around the silt suction port at the bottom of the pump body. A silt stirring frame is fixed to the side wall of the pump body. A stirring vertical cylinder is fixed to the silt stirring frame. A silt stirring shaft is rotatably installed through the stirring vertical cylinder. Silt stirring blades are installed on the silt stirring shaft for stirring the silt. During dredging, the silt stirring blades agitate the silt that has settled and hardened on the river bottom. The silt and water are disturbed and dispersed into a mixture of mud and water. The silt is filtered through the filter screen and then pumped out by the pump body to achieve dredging. However, the thickness of the silt accumulated after a long period of sedimentation is usually quite thick. The position of the silt stirring blades relative to the pump body is fixed, which limits the stirring range of the silt stirring blades and affects the effect of disturbing and dispersing the silt. This may cause the undispersed silt to block the filter holes on the filter screen, thereby affecting the dredging effect. SUMMARY

[0004] The present application provides a dredging equipment for water conservancy construction to solve the above problems.

[0005] The dredging equipment for water conservancy construction of the present application adopts the following technical solution: a dredging equipment for water conservancy construction, comprising a connecting frame and a disturbing mechanism. The upper end of the connecting frame is connected to a moving mechanism, and the lower end is fixed with a suction pump. The inlet of the suction pump is downwardly arranged. A support disc with vertical axis is fixed on the inlet of the suction pump. A through hole is provided at the axis of the support disc. The through hole is in communication with the inlet of the suction pump. A protective cylinder is coaxially arranged below the support disc. The protective cylinder covers the outside of the through hole. The upper end of the protective cylinder is fixedly installed on the support disc. A plurality of suction holes are provided on the side wall of the protective cylinder. The protective cylinder prevents large pieces of silt from entering the suction pump and causing the suction pump to jam.

[0006] The disturbing mechanism is provided with a plurality of disturbing mechanisms distributed circumferentially along the protective cylinder; the disturbing mechanism comprises a disturbing shaft; the disturbing shaft is vertically arranged, and a pulley is coaxially and rotatably arranged at the upper end of the disturbing shaft; the pulley is slidably arranged at the lower end of the supporting disc around the axis of the supporting disc; a disturbing blade group is fixed at the lower end of the disturbing shaft; a driving mechanism is arranged between the disturbing shaft and the supporting disc; the driving mechanism is used to drive the disturbing shaft to drive the disturbing blade group to revolve around the axis of the protective cylinder while driving the disturbing shaft to drive the disturbing blade group to rotate around the axis of the disturbing shaft. By revolving around the protective cylinder while rotating, the disturbing area of the disturbing blade group is expanded, and the disturbance and dispersion of the sludge are promoted, so as to reduce the probability of the sludge blocking the suction hole and improve the dredging effect. The disturbing blade group comprises a plurality of disturbing blades distributed around the disturbing shaft; the disturbing blades are arranged in a radial direction of the disturbing shaft; the end of the disturbing blade away from the disturbing shaft is provided with a disturbing end; the disturbing ends of the plurality of disturbing blades are sequentially connected to enclose a circle in a cam shape. When the disturbing shaft rotates, the disturbing blade group in the cam shape is driven to eccentrically rotate. Due to the difference in the length of the disturbing blades, the linear speed of the disturbing ends of the disturbing blades is different, the disturbance of the sludge is promoted, and the dredging effect is improved. When the disturbing end far away from the disturbing shaft rotates and approaches the protective cylinder, the gap between the disturbing end and the protective cylinder is narrowed, so that the water flow fluctuates when the slurry flows through the gap between the disturbing end and the protective cylinder, the slurry impacts the protective cylinder and makes the protective cylinder vibrate, so as to shake off the sludge blocked at the suction hole, thereby preventing the suction hole from being blocked.

[0007] Further, the driving mechanism comprises a center gear ring, an outer gear ring, a planetary gear and a power structure; the center gear ring is coaxially arranged outside the protective cylinder and is rotatably arranged at the lower end of the supporting disc; the outer gear ring is coaxially arranged outside the center gear ring; the outer gear ring is fixed at the lower end of the supporting disc; the planetary gear is arranged between the center gear ring and the outer gear ring and below the pulley; the planetary gear is coaxially fixed on the disturbing shaft; the planetary gear and the center gear ring are engaged; the planetary gear and the outer gear ring are engaged. The power structure is used to drive the center gear ring to rotate, so as to drive the planetary gear to drive the disturbing shaft to rotate around the axis of the protective cylinder while revolving around the axis of the protective cylinder.

[0008] Further, the disturbing mechanism further comprises a matching blade group and a transmission assembly; the matching blade group is arranged above the disturbing blade group; the transmission assembly is used to drive the matching blade group to rotate around the disturbing shaft, and the rotating direction of the matching blade group is opposite to the rotating direction of the disturbing blade group, so as to make the flowing directions of the upper and lower layers of the sludge opposite, form an impact wave between the upper and lower layers of the sludge, make the sludge more dispersed and easier to be sucked and removed, and reduce the vortex formed by rotation and the concentration of impurities near the suction hole.

[0009] Further, the matching blade group comprises a matching cylinder; the matching cylinder is coaxially sleeved on the disturbing shaft and is above the disturbing blade; the matching cylinder is rotationally installed on the disturbing shaft; a plurality of matching blades are arranged at the lower end of the matching cylinder; the plurality of matching blades are distributed in the circumferential direction of the matching cylinder; the matching blades are arranged in the radial direction of the disturbing shaft; the end of the matching blades away from the disturbing shaft is provided as a matching end; the matching ends of the plurality of matching blades are sequentially connected to enclose a circle in the circumferential direction of the disturbing shaft and are in the shape of a cam.

[0010] Further, the transmission assembly comprises a transmission frame, an upper bevel gear, a lower bevel gear and a middle bevel gear; the transmission frame is rotationally matched with the disturbing shaft and is slidably installed on the lower end of the support disc around the axis of the protection cylinder; the upper bevel gear is coaxially fixed on the side wall of the disturbing shaft and is above the matching cylinder; the lower bevel gear is below the upper bevel gear and is coaxially fixed on the upper end of the matching cylinder; the middle bevel gear is arranged between the upper bevel gear and the lower bevel gear; the axis of the middle bevel gear is arranged in the radial direction of the disturbing shaft; the middle bevel gear is rotationally installed on the transmission frame; the middle bevel gear is meshed with the upper bevel gear; the middle bevel gear is meshed with the lower bevel gear. When the central gear ring rotates, the disturbing shaft is driven to rotate around the axis of the protection cylinder while revolving around the axis of the protection cylinder; in this process, the disturbing shaft drives the middle bevel gear to rotate through the upper bevel gear, the middle bevel gear drives the lower bevel gear to rotate, the lower bevel gear drives the matching cylinder to rotate, and the rotating direction of the matching cylinder is opposite to that of the disturbing shaft, so that the rotating direction of the matching blade is opposite to that of the disturbing blade.

[0011] Further, the disturbing blade and the matching blade are arranged in an inclined manner.

[0012] Further, a T-shaped groove is arranged at the lower end of the support disc; the T-shaped groove is annular; the vertical cross section of the pulley is in the shape of T; and the pulley is slidably installed in the T-shaped groove.

[0013] Further, the power structure comprises a power motor and a power gear ring; the power gear ring is coaxially fixed on the upper end surface of the central gear ring; the power motor is fixed on the support disc; an intermediate gear is fixed on the output shaft of the power motor; and the intermediate gear is meshed with the power gear ring.

[0014] Further, the connecting frame is fixed with a protection frame on the outer side.

[0015] The beneficial effects of the present application are as follows:

[0016] 1. The driving mechanism drives the stirring shaft to drive the stirring blade group to revolve around the axis of the protection cylinder while rotating around the axis of the stirring shaft. The disturbing blade group revolves around the protection cylinder while rotating, which expands the disturbing area of the silt and promotes the disturbance and dispersion of the silt, thereby reducing the probability of the undispersed silt blocking the suction hole and improving the dredging and desilting effect.

[0017] 2. When the disturbance shaft rotates, the cam-shaped disturbance blade group rotates eccentrically. Because the lengths of the blades are different, the linear velocities at the disturbance ends of the blades are different, which promotes the disturbance of the sludge and improves the effect of dredging. When the disturbance ends far from the disturbance shaft rotate and approach the protective cylinder, the gap between the disturbance ends and the protective cylinder narrows, so that when the sludge flows through the gap between the disturbance ends and the protective cylinder, water flow fluctuation is generated, the sludge impacts the protective cylinder and makes the protective cylinder vibrate, so as to prevent the sludge from being blocked in the suction hole.

[0018] 3. The rotating direction of the cooperation blade group is opposite to the rotating direction of the disturbance blade group, so that the flowing directions of the upper and lower layers of the sludge are opposite, impact fluctuation is formed between the upper and lower layers of the sludge, the sludge is more dispersed and easier to be sucked and removed, and the vortex formed by rotation is reduced, and the impurities are reduced to be concentrated near the suction hole.
