Description

Technical Field

[0001] This utility model relates to the technical field of sludge cleaning equipment, specifically a river sludge cleaning device. Background Technology

[0002] River sludge accumulation can cause multiple hazards, such as polluting water bodies, raising the riverbed and reducing flood control capacity, increasing the risk of flooding, hindering navigation and emitting foul odors, and damaging the riverside landscape and living environment. Therefore, it is necessary to clean up the river sludge.

[0003] In the prior art, the cleaning of river sludge is carried out by using a robotic arm to drive a bucket to excavate and clean the sludge in the river, such as the river dredging bucket proposed in patent application number "CN202322540228.7", which includes a bucket; this design facilitates the discharge of sewage in the bucket by cleaning the trough at the bottom of the bucket, which is beneficial to the river dredging operation.

[0004] However, in existing technologies, the bucket opening of river cleaning is open. When cleaning a flowing river, the flowing water in the river will wash away the sludge in the bucket, causing the sludge to be lost from the bucket, resulting in a reduction in the amount of sludge cleaned and the spread of pollutants in the sludge. Utility Model Content

[0005] The purpose of this invention is to provide a river sludge cleaning device to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A river sludge cleaning device includes a bucket mounted on an external robotic arm for scooping river sludge. A movable sealing plate is provided above the open end of the bucket. The inclination of the sealing plate is the same as that of the open end of the bucket. The sealing plate is used to seal the open end of the bucket after the bucket has scooped the sludge. The bottom of the sealing plate extends into the interior of the bucket.

[0008] A waterproof motor is fixedly installed on the top of the bucket, and a control screw is fixedly connected to the output end of the waterproof motor. A control plate is fixedly connected to one side of the top of the sealing plate. The control screw and the control plate are threaded together and used to drive the control plate and the sealing plate to tilt in the direction of the bucket opening.

[0009] Preferably, the sealing plate has grooves arranged in a linear array on both sides to form a comb-like structure on both sides of the sealing plate.

[0010] Preferably, a fixing rod is fixedly connected to the top of the bucket, and a top positioning sleeve and a bottom positioning sleeve are fixedly connected to the top and bottom of the fixing rod, respectively. The bottom of the top positioning sleeve and the top of the bottom positioning sleeve are both designed with an arc shape.

[0011] Both sides of the control panel are fixedly connected to connecting plates, and positioning holes are opened on the connecting plates. The top positioning sleeve and the bottom positioning sleeve are adapted to the positioning holes.

[0012] Preferably, a limiting ring is fixedly connected to the bottom positioning sleeve, and the limiting ring is used to limit the downward movement distance of the connecting plate and the control plate.

[0013] Preferably, an L-shaped fixing plate is fixedly connected to the top of the fixing rod, a pressure spring is fixedly connected to the L-shaped fixing plate, a positioning pressure plate is fixedly connected to one end of the pressure spring, and a guide plate inclined away from the connecting plate is fixedly connected to the bottom of the positioning pressure plate.

[0014] Preferably, the top of the positioning plate and the top of the L-shaped fixing plate are slidably connected.

[0015] The beneficial effects of this utility model are:

[0016] This invention, by using a bucket driven by an external robotic arm to excavate sludge, can activate a waterproof motor to move a control plate downwards. The control plate then moves a sealing plate downwards to seal the opening of the bucket. This prevents water flow from impacting the sludge inside the bucket when cleaning sludge in a flowing river, reducing sludge loss and preventing the spread of pollutants from the sludge, thus increasing the amount of sludge that can be cleaned.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 A river sludge cleaning device includes a bucket 1 mounted on an external robotic arm for sludge removal. The external robotic arm can be an excavator robotic arm or a robotic arm capable of rotation and extension in the prior art. The movement of the robotic arm is prior art and will not be described in detail here.

[0026] A movable sealing plate 2 is provided above the opening end of the bucket 1. The inclination of the sealing plate 2 is the same as that of the opening end of the bucket 1, so that the sealing plate 2 can move parallel to the opening end of the bucket 1. The sealing plate 2 is used to seal the opening end of the bucket 1 after the bucket 1 has scooped up sludge. The bottom of the sealing plate 2 extends into the interior of the bucket 1, and the top of the bucket 1 has an opening to facilitate the passage of the sealing plate 2.

[0027] like Figure 1 and Figure 2 A waterproof motor 3 is fixedly installed on the top of the bucket 1. The waterproof motor 3 is an IP68-rated FT85135 waterproof motor in the prior art. It is powered by a waterproof cable connected to an external mechanism. A control screw 4 is fixedly connected to the output end of the waterproof motor 3. A control plate 5 is fixedly connected to one side of the top of the sealing plate 2. The control screw 4 and the control plate 5 are threaded together and used to drive the control plate 5 and the sealing plate 2 to tilt in the direction of the opening end of the bucket 1.

[0028] like Figure 1 The sealing plate 2 has grooves 201 arranged in a linear array on both sides to form a comb-like structure on both sides of the sealing plate 2. Through the comb-like structure on both sides of the sealing plate 2, the sealing plate 2 can close the opening end of the bucket 1. After the bucket 1 digs up the silt, the water and some fine sludge inside the bucket 1 can flow out, increasing the proportion of sludge dug out by the bucket 1 and reducing the water content in the sludge.

[0029] like Figure 2 , Figure 3 and Figure 4 The top of the bucket 1 is fixedly connected to a fixing rod 6. The fixing rod 6 is inclined and has the same inclination as the control screw 4. The top and bottom of the fixing rod 6 are respectively fixedly connected to a top positioning sleeve 7 and a bottom positioning sleeve 8. The bottom of the top positioning sleeve 7 and the top of the bottom positioning sleeve 8 are both designed with arc shape, making it easier for the top positioning sleeve 7 and the bottom positioning sleeve 8 to pass through the positioning hole 901.

[0030] Both sides of the control board 5 are fixedly connected to the connecting plate 9. The connecting plate 9 has a positioning hole 901. The top positioning sleeve 7 and the bottom positioning sleeve 8 are adapted to the positioning hole 901. The surfaces of the top positioning sleeve 7 and the bottom positioning sleeve 8 are covered with rubber pads, which can increase the friction between the top positioning sleeve 7 and the bottom positioning sleeve 8 and the connecting plate 9 when they pass through the positioning hole 901, thus assisting in the positioning of the connecting plate 9 and the control board 5.

[0031] like Figure 2 , Figure 3 and Figure 4 A limit ring 10 is fixedly connected to the bottom positioning sleeve 8. The limit ring 10 is used to limit the downward movement distance of the connecting plate 9 and the control plate 5. When the control plate 5 and the connecting plate 9 move downward, the bottom of the connecting plate 9 will touch the upper part of the limit ring 10. At this time, the control plate 5 and the connecting plate 9 will not continue to move downward.

[0032] like Figure 2 , Figure 3 and Figure 4 An L-shaped fixing plate 11 is fixedly connected to the top of the fixing rod 6. A pressure spring 12 is fixedly connected to the L-shaped fixing plate 11. A positioning pressure plate 13 is fixedly connected to one end of the pressure spring 12. A guide plate 131 inclined away from the connecting plate 9 is fixedly connected to the bottom of the positioning pressure plate 13. The pressure spring 12 presses the positioning pressure plate 13 towards the connecting plate 9.

[0033] like Figure 3 and Figure 4 The top of the positioning plate 13 and the top of the L-shaped fixing plate 11 are slidably connected;

[0034] The positioning plate 13 has a protrusion on its top, and the L-shaped fixing plate 11 has a horizontal groove below its top. The protrusion on the top of the positioning plate 13 is located in the horizontal groove, so as to realize the sliding connection between the top of the positioning plate 13 and the top of the L-shaped fixing plate 11 (not shown in the figure).

[0035] The working principle of the river sludge cleaning device provided by this utility model is as follows:

[0036] After the bucket 1 excavates sludge under the drive of the external robotic arm, the waterproof motor 3 drives the control screw 4 to rotate clockwise, which in turn drives the control plate 5 to move down. The control plate 5 then drives the sealing plate 2 to move down, which in turn seals the open end of the bucket 1, thus sealing the excavated sludge inside the bucket 1. At this time, during the upward lifting of the bucket 1, the flowing water in the river will not impact the sludge inside the bucket 1, and the sludge inside the bucket 1 will not be lost due to the water flow.

[0037] When it is necessary to release the sludge in bucket 1, the waterproof motor 3 drives the control screw 4 to rotate counterclockwise, which drives the control plate 5 to move upward. The control plate 5 then drives the sealing plate 2 to move upward. At this time, the sealing plate 2 no longer seals the opening end of bucket 1, and the sludge in bucket 1 can be released.

[0038] As the control plate 5 and the sealing plate 2 move upward, the connecting plate 9 will move upward together. The connecting plate 9 presses against the inclined surface of the guide plate 131 and gets stuck between the two positioning plates 13. The pressure spring 12 presses against the positioning plates 13, and the positioning plates 13 press against the connecting plate 9 and the control plate 5, which helps to position the sealing plate 2.

[0039] Compared with related technologies, the river sludge cleaning device provided by this utility model has the following beneficial effects:

[0040] This invention, by excavating sludge with the help of an external robotic arm, can activate a waterproof motor 3 to move the control plate 5 downwards. The control plate 5 then moves the sealing plate 2 downwards to seal the opening of the bucket 1. This prevents the water flow from impacting the sludge inside the bucket 1 when cleaning sludge in a flowing river, reducing the loss of sludge inside the bucket 1, preventing the spread of pollutants in the sludge, and increasing the amount of sludge cleaned.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
