Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and specifically relates to a river channel cleaning device for water conservancy projects. Background Art

[0002] River channel dredging generally refers to the treatment of river channels, which belongs to water conservancy projects. 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, thereby playing a role in dredging. River channel dredging belongs to a category of river treatment. By cleaning the silt at the bottom of the river and reducing the accumulation of garbage at the bottom of the river, it plays a very important role in dredging the river.

[0003] The existing river channel cleaning devices do not have the structure or function of lifting garbage. For example, the invention patent with the publication number CN104563075B discloses a river channel cleaning device, which includes a fixed body. A connecting body is provided on the side surface of the fixed body. A number of grooves are provided on the fixed body, and a telescopic elbow is provided in each groove. One end of each elbow is fixedly connected with an adjusting rod. The fixed body and the connecting body are made of rigid foam, and the elbow and the adjusting rod are of an integral hollow structure. The main body of this patent is made of floating foam materials, and elbows for gathering floating objects are provided on these floating materials. This setting method can clean the river channel in a large area in a carpet-like manner.

[0004] However, when the above patent is used, the garbage accumulated on the river bed still stays on the river bed or is discharged to the bank side as the river channel cleaning device advances, causing water quality pollution on the near-shore side of the river channel. These garbage need to be salvaged twice, consuming manpower, material resources and time, and having great limitations.

[0005] Therefore, designing a river channel cleaning device for water conservancy projects with the structure or function of lifting garbage to avoid problems such as secondary salvage and the stench of water quality on the near-shore side after dredging is the primary problem that those skilled in the art should solve at present. Summary of the Invention

[0007] The technical solution of the present invention is: A river channel cleaning device for water conservancy projects includes a motor box, and side sealing plates are fixedly installed at both ends of the motor box. It also includes;

[0008] Two interception nets, which are used to block garbage and larger silt blocks. The two interception nets are respectively arranged at the upper and lower ends of the two side sealing plates, and each interception net is fixedly connected with the two side sealing plates;

[0009] An end-edge sealing plate, both ends of the end-edge sealing plate are fixedly connected to two side-edge sealing plates, and a plurality of through holes are opened on the end-edge sealing plate;

[0010] A plurality of output shafts, the plurality of output shafts are fixedly connected to the motor box through couplings, and one ends of the plurality of output shafts all penetrate through the through holes and extend to the outer ends of the end-edge sealing plate. Auger blades are arranged on the circumferential outer walls of the plurality of output shafts, and the inner diameter of the through hole is larger than the diameter of the auger blade.

[0011] Preferably, positioning plates are fixedly installed on both of the two side-edge sealing plates, and connecting holes are opened at equidistant intervals inside the two positioning plates.

[0012] Preferably, a water pumping mechanism is installed inside each of the plurality of connecting holes. The water pumping mechanisms are all installed in the connecting holes, and the water pumping mechanisms are used to pump the water in the area surrounded by the motor box, the side-edge sealing plates and the end-edge sealing plate.

[0013] Preferably, each of the water pumping mechanisms includes a water pumping rubber plug and a water pumping pipe. The water pumping rubber plug adopts a cap-shaped structure and is hollow inside.

[0014] Preferably, the narrow end of the water pumping rubber plug is fixedly installed at the inner port of the connecting hole, and the center position of the wide end of the water pumping rubber plug is fixedly connected to the water pumping pipe.

[0015] Preferably, a first water pumping cone sleeve is fixed to the inner wall of the middle of the water pumping pipe, and a second water pumping cone sleeve is fixed to the inner wall of the outer port of the water pumping pipe. A third water pumping cone sleeve is fixed to the inner wall of the second water pumping cone sleeve.

[0016] Preferably, the taper of the first water pumping cone sleeve is greater than the taper of the second water pumping cone sleeve, and the directions of the first water pumping cone sleeve and the second water pumping cone sleeve are the same.

[0019] The present invention hereby provides a river cleaning device for water conservancy projects through improvement. Compared with the prior art, it has the following improvements and advantages:

[0020] First, the interception net of the present invention has small and dense meshes, which can pass water flow and block garbage and larger silt blocks. When the device is lifted, the water in the device flows down from the interception net, and the garbage remains in the interception net and rises with the lifting of the device until it is out of the river surface.

[0022] Thirdly, the pumping rubber plug of the present invention has the functions of buffering and storing water. When water is stored inside the pumping rubber plug, the pumping rubber plug can maintain the balance of internal and external water pressures to prevent water from flowing back into the device from the connecting hole through the water storage capacity of the pumping rubber plug.

[0023] Fourthly, three barrier structures are arranged in the pumping pipe of the present invention, namely the first pumping cone sleeve, the second pumping cone sleeve and the third pumping cone sleeve. The stacked structural arrangement of the first pumping cone sleeve, the second pumping cone sleeve and the third pumping cone sleeve can effectively intercept debris and garbage in the water, that is, only water is pumped out without pumping away too much garbage and debris. At the same time, it can prevent larger waste and garbage from clogging the pumping mechanism, thereby ensuring the river cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. 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 belong to the scope of protection of the present invention.

[0032] The present invention provides a river cleaning device for water conservancy projects through improvement. The technical solution of the present invention is as follows:

[0033] As Figures 1 - 4 shown, a river cleaning device for water conservancy projects includes a motor box 1, and side sealing plates 6 are fixedly installed at both ends of the motor box 1. It also includes;

[0034] Two intercepting nets 18, the intercepting nets 18 are used to block garbage and larger silt blocks. The two intercepting nets 18 are respectively arranged at the upper and lower ends of the two side sealing plates 6, and each intercepting net 18 is fixedly connected to the two side sealing plates 6; the intercepting nets 18 have small and dense mesh holes, can pass water flow, block garbage and larger silt blocks. During the process of lifting the device, the water in the device flows down along the intercepting nets 18, while the garbage remains in the intercepting nets 18 and rises with the device until it is lifted out of the river surface. The garbage is lifted up, and the intercepting nets 18 can be opened to clean the garbage, thus avoiding problems such as secondary salvage and the stench of the water quality on the near-shore side after dredging.

[0035] An end sealing plate 16, the two ends of the end sealing plate 16 are fixedly connected to the two side sealing plates 6, and a plurality of through holes 17 are opened on the end sealing plate 16; the through holes 17 are used to pass silt, branches, leaves and other garbage and enter the two intercepting nets 18.

[0036] A plurality of output shafts, the plurality of output shafts are fixedly connected to the motor box 1 through couplings, and one end of each of the plurality of output shafts penetrates through the through hole 17 and extends to the outer side end of the end sealing plate 16. Screw blades 15 are arranged on the circumferential outer walls of the plurality of output shafts, and the inner diameter of the through hole 17 is larger than the diameter of the screw blades 15; with the above structure, the output shafts and the screw blades 15 are driven to start by the motor in the motor box 1. The screw blades 15 rotate, can extract silt, branches, leaves and other garbage outside the device, and the silt and garbage can enter the inner side of the device from the through hole 17, so as to be collected and convenient for lifting; at the same time, under the action of the screw blades 15, the through hole 17 can be prevented from being blocked, and some waste garbage can be squeezed and crushed to further facilitate the subsequent cleaning of the waste garbage.

[0037] As a further solution of the present invention, positioning plates 7 are fixedly installed on both side sealing plates 6, and connecting holes 8 are arranged at equal distances inside the two positioning plates 7.

[0038] Further, a pumping mechanism 9 is installed inside each of the multiple connecting holes 8. The pumping mechanisms 9 are all installed in the connecting holes 8. The pumping mechanism 9 is used to pump the water in the area surrounded by the motor box 1, the side sealing plate 6 and the end sealing plate 16, so that there is a large space in the device to carry as much river bottom garbage as possible.

[0039] Further, each pumping mechanism 9 includes a pumping rubber plug 10 and a water suction pipe 11. The pumping rubber plug 10 adopts a cap-like structure and is hollow inside. With the above structure, the pumping rubber plug 10 has the functions of buffering and storing water. When there is water stored inside the pumping rubber plug 10, the pumping rubber plug 10 can maintain the internal and external water pressure balance and prevent water from flowing back into the device through the connecting hole 8.

[0040] As a further solution of the present invention, the narrow end of the pumping rubber plug 10 is fixedly installed at the inner port of the connecting hole 8, and the center position of the wide end of the pumping rubber plug 10 is fixedly connected to the water suction pipe 11.

[0041] As a further solution of the present invention, a first water suction cone sleeve 12 is fixed to the inner wall of the middle of the water suction pipe 11, and a second water suction cone sleeve 13 is fixed to the inner wall of the outer port of the water suction pipe 11. A third water suction cone sleeve 14 is fixed to the inner wall of the second water suction cone sleeve 13.

[0042] Further, the taper of the first water suction cone sleeve 12 is greater than the taper of the second water suction cone sleeve 13, and the directions of the first water suction cone sleeve 12 and the second water suction cone sleeve 13 are the same. The directions of the third water suction cone sleeve 14 and the first water suction cone sleeve 12 and the second water suction cone sleeve 13 are all opposite. With the above structure, three blocking structures are arranged inside the water suction pipe 11, namely the first water suction cone sleeve 12, the second water suction cone sleeve 13 and the third water suction cone sleeve 14. By using the layered structure arrangement of the first water suction cone sleeve 12, the second water suction cone sleeve 13 and the third water suction cone sleeve 14, the sundries and garbage in the water are effectively intercepted, that is, only water is pumped out externally, and too much garbage and sundries will not be pumped away. At the same time, it can prevent larger waste garbage from blocking the pumping mechanism 9, so as to ensure the river cleaning effect.

[0043] As a further solution of the present invention, a mounting seat 2 is fixedly installed at one end of the motor box 1 away from the intercepting net 18, and a mounting groove 3 is opened at the middle axis of the outer side wall of the mounting seat 2 away from the motor box 1.

[0044] Further, a rotating plate 4 is rotatably connected to the mounting groove 3 through a movable shaft, and a connecting plate 5 is fixedly installed on the outer side wall of the rotating plate 4. The connecting plate 5 is connected to an external propulsion machine. The rotating plate 4 can rotate flexibly in the mounting groove 3 to smoothly adjust the angle of the entire device relative to the propulsion machine, avoiding the problem that the device directly falls into the water, is directly inserted or obliquely inserted into the riverbed at a large angle, resulting in device damage or difficult propulsion.

[0045] The specific working method is as follows: First, connect the device to a propulsion machine, such as a hull. The connection part between the device and the propulsion machine is the connecting plate 5. Under the rotational mating structure between the rotating plate 4 and the installation groove 3, the connecting plate 5 can flexibly adjust the angle, so that after the device falls into the water and contacts the riverbed, it can be tilted or directly laid flat. After the device falls into the water and contacts the riverbed, start the motor in the motor box 1, and each output shaft drives the auger blade 15 to rotate. As the hull advances, the device moves along the riverbed. During the rotation of the auger blade 15, it stirs the river bottom silt and various wastes. Driven by the auger blade 15, these wastes enter the interception net 18 through the through hole 17. To ensure that the device can wrap as much waste as possible at one time, draw the water in the interception net 18 through the pipeline connected to the outer end of the connection hole 8. The water, together with the wastes and garbage, approaches the pumping mechanism 9. When passing through the water suction pipe 11, it is successively blocked by the first water suction cone sleeve 12, the second water suction cone sleeve 13, and the third water suction cone sleeve 14. The waste and garbage cannot pass through the water suction pipe 11 and can only remain in the interception net 18. At the same time, it can prevent larger waste and garbage from blocking the pumping mechanism 9. Finally, lift the device out of the water. The water flows out through the interception net 18, while the waste and garbage are intercepted by the interception net 18 and stored in the interception net 18. The waste and garbage are lifted up, and opening the interception net 18 can clean the waste and garbage.

[0046] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
