Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and specifically to an efficient water conservancy construction dredging device. Background Art

[0002] Water conservancy projects are projects built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating disasters and bringing benefits, and are also called water projects. Water is an indispensable precious resource for human production and life. However, its natural state does not fully meet the needs of humans. Only by building water conservancy projects can the water flow be controlled, flood disasters be prevented, and the regulation and distribution of water volume be carried out to meet the needs of people's lives and production for water resources. There are many water conservancy project equipment, and the water conservancy construction waterproof and drainage device is one of them.

[0003] Through mechanical equipment, the silt deposited at the bottom of the river is stirred into a turbid water state and flows away with the river water, thus playing a role in dredging. River silt accumulation will affect the normal functioning of various functions such as flood control, waterlogging drainage, irrigation, water supply, and navigation. Therefore, timely dredging is of great significance for people's living environment and production conditions.

[0004] In the existing technology during the dredging process, there is a large amount of water in the silt. The existing technology cannot separate the water in the silt in time, resulting in a large amount of sewage flowing wantonly during the stacking process of the dredged silt and being out of control. To solve this technical problem, an efficient water conservancy construction dredging device is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide an efficient water conservancy construction dredging device to solve the problems raised in the above background art.

[0008] A suction pipe provided on the device main body, the output end of the suction pipe is connected to the suction head, and the silt is sucked through the suction head;

[0009] A water removal component provided inside the device main body;

[0010] The feed inlet of the water removal component is communicated with the output end of the suction pipe, and the water removal component is used to press out the water in the silt;

[0011] The water removal component includes a housing, inside which a rotating shaft is eccentrically arranged. A plurality of telescopically arranged partition members are arrayed on the outer side of the rotating shaft. The partition members divide the interior of the housing into multiple independent spaces. Due to the eccentric arrangement of the rotating shaft, the space between adjacent partition members periodically becomes larger and smaller. A reverse osmosis layer is provided on the surface of the housing for discharging water to prevent water from reverse osmosis into the interior of the housing. An inlet and an outlet are provided on the housing. The inlet is arranged at the position where adjacent two partition members are in the large space, and the outlet is arranged at the position where adjacent two partition members are in the small space. The inlet is communicated with the output end of the straw.

[0012] In the present invention, when the straw sucks the sludge into the water removal component through the suction head, the rotating shaft inside the water removal component rotates under the push of the sludge, and then drives the partition members. During the rotation of the partition members, since the distance between adjacent two partition members is continuously decreasing, the sludge is continuously squeezed. During the squeezing process, the water in the sludge is discharged through the reverse osmosis layer. When the space becomes the smallest position, it is discharged through the inlet. In this way, the power of the sludge itself can be utilized to discharge the water in the sludge, saving energy. The present invention effectively discharges the water in the sludge and utilizes the power of the sludge itself, saving energy; the present invention effectively discharges the water in the sludge and utilizes the power of the sludge itself, saving energy.

[0013] As a further scheme of the present invention: A negative pressure pump is also provided on the straw.

[0014] As a further scheme of the present invention: The housing includes a multi-layer structure.

[0015] As a further scheme of the present invention: The housing is sequentially provided with a protective layer, a reverse osmosis layer, a conveying channel and a support shell. The protective layer is inside, and the support shell is outside for support.

[0016] As a further scheme of the present invention: The partition member includes a fixing plate fixedly installed on the rotating shaft. An activity plate is elastically arranged at one end of the fixing plate away from the rotating shaft, and one end of the activity plate away from the rotating shaft abuts against the inner wall of the housing.

[0017] As a further scheme of the present invention: A collecting pipe is connected between adjacent two activity plates, and a collecting pipe with an elastic structure is also connected between adjacent two fixing plates.

[0018] As a further scheme of the present invention: The collecting pipe is a multi-layer structure. The surface layer of the collecting pipe is an elastic support layer, and the interior of the collecting pipe is a reverse osmosis pipe made of a reverse osmosis membrane. The reverse osmosis pipe is arranged inside the elastic support layer.

[0019] As a further solution of the present invention: a filter screen is provided at the suction end of the straw, and a stone inlet is further provided on the material suction head, and the stone inlet is arranged below the filter screen.

[0020] As a further solution of the present invention: the stone inlet is communicated with a stone conveying cavity provided on the device main body, and a rotating conveying and cleaning roller is arranged in the conveying cavity, and a conveyor belt cooperating with the conveying and cleaning roller is also provided.

[0021] As a further solution of the present invention: the conveying and cleaning roller includes a rotating shaft with a rotating shaft installed on the device main body, a plurality of driving blades are arranged in an array on the surface of the rotating shaft, a plurality of drain holes are arranged in an array on the surface of the driving blade, and a brush is arranged at the bottom of the driving blade.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: when the straw sucks the silt into the water removal component through the material suction head, the rotating shaft inside the water removal component rotates under the push of the silt, and then drives the isolation member. During the rotation of the isolation member, since the distance between two adjacent isolation members is continuously decreasing, the silt is continuously squeezed in this way. During the squeezing process, the water in the silt is discharged through the reverse osmosis layer. When the space reaches the minimum position, it is discharged through the feed port. In this way, the power of the silt itself can be utilized to discharge the water in the silt, saving energy. The present invention effectively discharges the water in the silt and utilizes the power of the silt itself, saving energy. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 to 3 , in the embodiments of the present invention, it is a structural diagram of an efficient water conservancy construction dredging device provided for the embodiments of the present invention, including: device main body 1; material suction head 2 provided on the device main body 1;

[0031] Suction pipe 3 provided on the device main body 1, the output end of the suction pipe 3 is connected to the material suction head 2, and the silt is sucked through the material suction head 2;

[0032] Water removal component 4 provided inside the device main body 1;

[0033] The feed port 46 of the water removal component 4 is communicated with the output end of the suction pipe 3, and the water removal component 4 is used to press out the water in the silt;

[0034] Specifically, the water removal component 4 includes a housing 41, a rotating shaft 42 is eccentrically arranged inside the housing 41, a plurality of telescopically arranged isolation members are arrayed outside the rotating shaft 42, and the isolation members divide the inside of the housing 41 into a plurality of independent spaces. Due to the eccentric arrangement of the rotating shaft 42, the space between adjacent isolation members periodically becomes larger and smaller. The surface of the housing 41 is provided with a reverse osmosis layer 412 for discharging water to prevent water from reverse osmosis into the inside of the housing 41; the housing 41 is provided with a feed port 46 and a discharge port 45, the feed port 46 is arranged at the position where adjacent two isolation members are in a large space, and the discharge port 45 is arranged at the position where adjacent two isolation members are in a small space; the feed port 46 is communicated with the output end of the suction pipe 3.

[0035] Specifically, when the suction pipe 3 sucks the sludge into the water removal component 4 through the suction head 2, the rotating shaft 42 inside the water removal component 4 rotates under the push of the sludge, thereby driving the isolation component. During the rotation of the isolation component, the distance between two adjacent isolation components continuously decreases, so as to continuously squeeze the sludge. During the squeezing process, the water in the sludge is discharged through the reverse osmosis layer 412. When the space reaches the minimum position, it is discharged through the feed port 46. In this way, the power of the sludge itself can be utilized to discharge the water in the sludge, saving energy. The present invention effectively discharges the water in the sludge and utilizes the power of the sludge itself, saving energy.

[0036] As a preferred embodiment of the present invention, a negative pressure pump 32 is further provided on the suction pipe 3, and the negative pressure pump 32 is provided to provide power for transporting the sludge.

[0037] As Figure 2 shown, as a preferred embodiment of the present invention, the housing 41 includes a multi-layer structure. Specifically, the housing 41 is sequentially provided with a protective layer 411, a reverse osmosis layer 412, a conveying channel 413, and a support shell 414. The protective layer 411 is inside, and the support shell 414 is outside for support; the protective layer 411 is used to protect the reverse osmosis layer 412, and the sewage enters the conveying channel 413 through the reverse osmosis layer 412, and then the conveying channel 413 is connected to an external pipeline for discharge. In this way, during the squeezing process of the sludge, the water can be discharged through the reverse osmosis layer 412 and the conveying channel 413.

[0038] As Figure 1 、 3 shown, as a preferred embodiment of the present invention, the isolation component includes a fixing plate 43 fixedly installed on the rotating shaft 42. An activity plate 44 is elastically provided at one end of the fixing plate 43 away from the rotating shaft 42. One end of the activity plate 44 away from the rotating shaft 42 abuts against the inner wall of the housing 41. The internal cross-sectional area of the housing 41 can be set to be circular or elliptical. This setting realizes the telescopic mechanism of the isolation component.

[0039] As Figure 4 shown, as a preferred embodiment of the present invention, in order to further improve the drainage effect, the fixing plate 43 and the activity plate 44 can be set to have the same structure as the housing 41, so that drainage can be carried out at each position inside the water removal space, and thus the drainage effect can be improved.

[0040] The activity plate 44 is installed on the fixing plate 43 through an elastic telescopic rod. In this way, elastic installation is realized.

[0041] As Figure 3As shown, as a preferred embodiment of the present invention, in order to enable the water in the sludge inside the housing 41 to be fully absorbed, a collecting pipe 48 is connected between two adjacent movable plates 44, and a collecting pipe 48 with an elastic structure is also connected between two adjacent fixing plates 43. Specifically, the collecting pipe 48 is a multi-layer structure. The surface layer of the collecting pipe 48 is an elastic support layer, and the inside of the collecting pipe 48 is a reverse osmosis pipe made of a reverse osmosis membrane. The reverse osmosis pipe is arranged inside the elastic support layer, and the reverse osmosis pipe is output through a connecting pipe 47 arranged inside the fixing plate 43 and the movable plate 44. In this way, when the collecting pipe 48 can drain the water in the sludge in the middle position, the drainage efficiency is effectively improved, and the water in the sludge is effectively removed completely.

[0042] As a preferred embodiment of the present invention, the output end of the connecting pipe 47 is connected to the rotating shaft 42, and the conveying channel 413 on the housing 41 is also communicated with the internal flow channel of the rotating shaft 42. In this way, the water is discharged through the rotating shaft 42. The connecting pipe 47 is an elastic pipe.

[0043] As Figure 1 shown, as a preferred embodiment of the present invention, since there are stones in the sludge, in order to separate the stones from the sludge to facilitate the protection of the suction pipe 3, a filter screen 31 is provided at the suction end of the suction pipe 3, and a stone opening 21 is also provided on the suction head 2. The stone opening 21 is arranged below the filter screen 31. In this way, when the sludge passes through the filter screen 31, the filter screen 31 filters the sludge to separate the stones from the sludge.

[0044] As Figure 1 shown, as a preferred embodiment of the present invention, the bottom wall of the suction head 2 is inclined upward, so as to guide the sludge, so that the movement direction of the sludge is upward towards the inlet of the suction pipe 3, so that the sludge can be completely sucked into the suction pipe 3; at the same time, the stones hit the filter screen 31 on the suction pipe 3, and then fall into the stone opening 21 under their own gravity and are conveyed away.

[0045] In order to connect the stone opening 21 with a stone conveying cavity 22 provided on the device main body 1, a rotating conveying and cleaning roller 5 is arranged in the conveying cavity 22, and a conveyor belt 6 is also provided in cooperation with the conveying and cleaning roller 5; the conveying and cleaning roller 5 is used to convey the stones onto the conveyor belt 6. The conveyor belt 6 is used to output the stones.

[0046] As Figure 1 、 5As shown, as a preferred embodiment of the present invention, the conveying and cleaning roller 5 includes a rotating shaft 51 installed on the device body 1, a plurality of driving blades 52 are arranged in an array on the surface of the rotating shaft 51, a plurality of drainage holes are arranged in an array on the surface of the driving blade 52, and a brush 53 is arranged at the bottom of the driving blade 52, so that the stones can be cleaned, which is convenient for the secondary recycling of the stones.

[0047] As a preferred embodiment of the present invention, a flow channel is arranged inside the rotating shaft 51, and the flow channel inside the rotating shaft 51 is used to provide cleaning water for the drainage holes on the surface of the driving blades 52; the flow channel inside the rotating shaft 51 is connected with the flow channel inside the rotating shaft 42 through a pipeline, and the rotating shaft 42 transfers the water generated during the sludge extrusion process to the rotating shaft 51, thereby realizing the secondary utilization of the squeezed water. A drainage pump is also arranged inside the device body 1 to discharge the water after cleaning.

[0048] like Figure 1 As shown, as a preferred embodiment of the present invention, a rotating joint 421 for water supply is provided on the rotating shaft 42, and the rotating joint 421 is connected to the output end of the rotating shaft 51, so that the water collected in the water removal component 4 is transported to the transport cleaning roller 5 to clean the stones.

[0049] The working principle of the present invention is:

[0050] When the negative pressure pump 32 on the suction pipe 3 is powered on, the sludge is sucked into the water removal component 4 through the suction head 2. The rotating shaft 42 inside the water removal component 4 rotates under the push of the sludge, thereby driving the fixed plate 43 and the movable plate 44. During the rotation process, the distance between the two adjacent isolation members of the fixed plate 43 and the movable plate 44 is continuously reduced, so the sludge is continuously squeezed. During the squeezing process, the water in the sludge is discharged through the reverse osmosis layer 412 on the shell 41 and multiple collection pipes 48. When the space becomes the minimum position, it is discharged through the feed port 46. The squeezed water is input into the conveying and cleaning roller 5 through the 4 stone ports 21 on the rotating shaft 42. The conveying and cleaning roller 5 rotates to transport and clean the stones separated by 3. During the transportation process, the driving blade 52 sprays the cleaning water brush 53 to wipe the surface of the stone. In this way, the stone is cleaned in practice, and the cleaned stone is transported through the conveyor belt 6. In this way, the power of the sludge itself can be used to discharge the water in the sludge, saving energy. The present invention effectively discharges the water in the sludge and simultaneously recycles the water.
