Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a water conservancy engineering dredging device that is easy to collect. Background Technology

[0002] Dredging is a crucial task for maintaining the normal operation of water conservancy facilities such as rivers and reservoirs. During river construction, it's necessary to remove silt from the riverbed. This not only deepens the river, facilitating drainage and flood control, but also improves the cleanliness of the river water. However, the silt accumulated over a long period in the riverbed is highly viscous, making manual removal difficult.

[0003] To address the aforementioned issues, a search revealed a Chinese patent application (CN202323099849.2) disclosing a water dredging device. This device includes a mud pump and a pair of horizontally positioned pontoons. A fixing plate is fixedly connected between the tops of the pontoons, and the mud pump is tilted and fixedly connected above the fixing plate. The outer side of each pontoon has a recessed groove located below the pontoon, away from the mud pump's extraction end. This patent improves the device's convenience by completely inserting the mud pump's extraction end into the mud, eliminating the need to use tools to dig soil or stones to elevate the rear end of the dredging device. However, this patent has the following drawbacks: The insertion of the mud pump's extraction end into the mud via an adjustment mechanism relies on manual operation, requiring workers to be close to the water to manually operate the threaded rod. This adjustment is inefficient and unstable in complex riverbed environments, and can easily lead to falls into the water in slippery slope conditions. Therefore, it is inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water conservancy project dredging device that facilitates collection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A water conservancy project dredging device that is easy to collect includes a fixed base fixedly connected to the top surface of the hull, and the top surface of the fixed base is connected to a dredging and mud conveying assembly through a spacing adjustment structure.

[0007] The spacing adjustment structure includes a slide groove on the top surface of the fixed base, a stud rotatably connected to the inner wall of one side of the slide groove, a guide rod slidably connected to the inner wall of the slide groove, a support plate fixedly connected to the outer wall of one side of the fixed base, and a second motor fixedly connected to the top surface of the support plate. The output end of the second motor is connected to one end of the stud through a coupling, and the outer wall of the stud is connected to the inner wall of the support through threads.

[0008] As a further improvement of this utility model, a guide rod is fixedly connected to one side of the outer wall of the support, penetrating the inner wall of one side of the fixed seat.

[0009] As a further embodiment of this utility model: the dredging and sludge conveying assembly includes a cylinder, a conical crushing head rotatably connected to one end of the cylinder, a support plate fixedly connected to the other end of the cylinder, a motor fixedly connected to the top surface of the support plate, and a shaftless screw conveyor rotatably connected to the inner wall of one end of the cylinder, wherein the two main shafts of the shaftless screw conveyor are respectively connected to the output end of the motor and one end of the crushing head through connecting shafts.

[0010] The outer circumferential wall of the cylinder is connected to the top surface of the support by bolts.

[0011] As a further improvement of this utility model, the overall tilt angle of the cylinder is ≤15°.

[0012] As a further embodiment of this utility model: the outer circumferential walls of the cylinder near both ends are fixedly connected to an inlet and an outlet, respectively, upwards and downwards;

[0013] The cylinder body has a cylinder cover hinged to its outer circumference.

[0014] As a further improvement of this utility model: a collection box is provided on the bottom inner wall of the hull, and the same flexible hose is fixedly connected to one end of the inlet and outlet of the collection box.

[0015] The top edge of the collection box is hinged with a door.

[0016] As a further improvement of this utility model: a set of inclined composite pipes is fixedly connected to one side of the collection box. The composite pipes consist of a hollow column with filter holes inside the collection box and a drain pipe on the outer wall of one side of the collection box.

[0017] Compared with the prior art, this utility model provides a water conservancy project dredging device that is easy to collect, and has the following beneficial effects:

[0018] 1. This easy-to-collect dredging device for water conservancy projects, by setting up a spacing adjustment structure, lowers the dredging end of the cylinder into the silt area, controls the start of motor 2, drives the stud to rotate, and then causes the cylinder to move back and forth along the slide groove under the action of the guide rod, thereby adjusting the depth of the dredging and mud conveying component. It is easy to operate, reduces manual intervention, and improves the safety of use.

[0019] 2. This easy-to-collect dredging device for water conservancy projects controls the motor to start, which in turn drives the shaftless screw conveyor to rotate, so as to transport the silt entering the cylinder from the inlet upwards until it is output from the outlet. During the silt transport, the high-speed rotating crushing head drills and crushes the bottom of the riverbed, especially the hardened silt, and penetrates deep into the riverbed to ensure that the silt enters the inlet smoothly and improves the dredging effect.

[0020] 3. This easy-to-collect dredging device for water conservancy projects transports sludge through a dredging and conveying component, which is then guided by a hose to a collection box for temporary storage. Later, the box door can be opened to remove the sludge. After the sludge enters the collection box, the liquid in it seeps into the hollow filter column and is directly discharged through the drain pipe, thereby effectively reducing the water content in the sludge.

[0027] Example 1

[0028] A water conservancy project dredging device that is easy to collect, such as Figure 1-3As shown, the device includes a triangular fixing seat 1 that is bolted to the top surface of the hull 100. The top surface of the fixing seat 1 is connected to a dredging and conveying assembly via a spacing adjustment structure. The dredging and conveying assembly includes a cylinder 2, a conical crushing head 3 rotatably connected to one end of the cylinder 2, a support plate bolted to the other end of the cylinder 2, a motor 6 bolted to the top surface of the support plate, and a shaftless screw conveyor 601 rotatably connected to the inner wall of one end of the cylinder 2. The two main shafts of the shaftless screw conveyor 601 are respectively connected to the output end of the motor 6 and one end of the crushing head 3 via connecting shafts.

[0029] Preferably, the structure and operation of the shaftless screw conveyor 601 can be referred to the existing Is300 shaftless screw conveyor, which will not be described in detail here.

[0030] Preferably, the overall tilt angle of the cylinder 2 is ≤15° to ensure effective transport of sludge.

[0031] Furthermore, the outer circumferential walls of the cylinder 2 near both ends are respectively fixed with an inlet 201 and an outlet 203 upwards and downwards by bolts. When the dredging end of the cylinder 2 is lowered into the silt area, the control motor 6 is started during operation, which drives the shaftless screw conveyor 601 to rotate, so as to transport the silt entering the cylinder 2 from the inlet 201 upwards until it is output from the outlet 203. Moreover, during the silt transport, the high-speed rotating crushing head 3 will drill and crush the bottom of the riverbed, especially the compacted silt, and penetrate deep into the riverbed to ensure that the silt enters the inlet 201 smoothly and improve the dredging effect.

[0032] Furthermore, a cylinder cover 202 is hinged to the outer circumference of the cylinder 2; after the operation is completed, the cylinder cover 202 can be opened to clean the inside of the cylinder 2.

[0033] Furthermore, the spacing adjustment structure includes a groove on the top surface of the fixed base 1, a stud 801 rotatably connected to the inner wall of one side of the groove, a guide rod 5 slidably connected to the inner wall of the groove, a support plate fixed to the outer wall of one side of the fixed base 1 by bolts, and a motor 8 fixed to the top surface of the support plate by bolts. The output end of the motor 8 is connected to one end of the stud 801 through a coupling. The outer wall of the stud 801 is connected to the inner wall of the support 4 by threads. The outer circumference of the cylinder 2 is connected to the top surface of the support 4 by bolts.

[0034] Furthermore, a guide rod 5 that penetrates the inner wall of one side of the fixed seat 1 is fixed to one side of the outer wall of the support 4 by bolts; the guide rod 5 provides auxiliary support and improves the stability of the cylinder 2 when it is displaced.

[0035] The control motor 8 starts, driving the stud 801 to rotate, which in turn causes the cylinder 2 to move back and forth along the slide groove under the action of the guide rod 5, thereby adjusting the depth of the dredging and mud conveying component. The operation is convenient.

[0036] Working principle: The control motor 8 starts, driving the stud 801 to rotate. This causes the cylinder 2, driven by the guide rod 5, to move back and forth along the slide groove under the action of the spiral, thereby adjusting the depth of the dredging and conveying assembly. When the dredging end of the cylinder 2 is lowered into the silt area, the control motor 6 starts, driving the shaftless screw conveyor 601 to rotate so as to convey the silt entering the cylinder 2 from the inlet 201 upwards until it is output from the outlet 203. During the silt conveying, the high-speed rotating crushing head 3 drills and crushes the bottom of the riverbed, especially the compacted silt.

[0037] Example 2

[0038] A water conservancy project dredging device that is easy to collect, such as Figure 1-3 As shown, in order to reduce the water content in the silt, this embodiment makes the following improvements based on embodiment 1: a collection box 7 is placed on the bottom inner wall of the hull 100, and the inlet and outlet 203 of the collection box 7 are fixed to the same hose 9 by bolts; a box door 701 is hinged to the top edge of the collection box 7; the silt transported by the dredging and sludge conveying assembly is guided to the collection box 7 through the hose 9 for temporary storage, and the box door 701 can be opened later to uniformly remove the silt.

[0039] Furthermore, a set of inclined composite pipes is fixed to one side of the collection box 7 near the top with bolts. The composite pipes consist of a filter hole hollow column 702 set inside the collection box 7 and a drain pipe set on the outer wall of one side of the collection box 7. After the sludge enters the collection box 7, the liquid in it seeps into the filter hole hollow column 702 and is directly discharged through the drain pipe, thereby effectively reducing the water content in the sludge.

[0040] Working principle: During operation, the control motor 6 starts, which in turn drives the shaftless screw conveyor 601 to rotate, so as to transport the silt entering the cylinder 2 from the inlet 201 upwards until it is output from the outlet 203. During the silt transportation, the high-speed rotating crushing head 3 drills and crushes the riverbed bottom, especially the compacted silt, when it comes into contact with it. The silt transported by the dredging and conveying assembly is guided to the collection box 7 through the hose 9 for temporary storage. Later, the silt can be uniformly removed by opening the box door 701.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
