Description

Technical Field

[0001] The utility model relates to the technical field of trash rack cleaning, in particular to an adjusting component and an underwater trash rack cleaning device. Background Art

[0002] A trash rack is a grating structure consisting of multiple bars, beams, and a frame, with the bars spaced regularly apart. Its function is to intercept floating debris on the water surface, ensuring sufficient strength, rigidity, and stability. Installing a trash rack at the head of a hydropower station effectively prevents waste from the water from entering the turbines, ensuring their normal operation.

[0003] Cleaning a trash rack typically requires a gantry crane to lift it from its opening onto a platform. Operators then use high-pressure water jets to flush the sludge from the rack bars. While this method is quick and easy, due to the operator's limited attention span, some areas may be overlooked during the lengthy cleaning process, resulting in incomplete cleaning of the rack bars.

[0004] To overcome this problem, engineers often use underwater cleaning devices to achieve automated cleaning. After the operator removes the bars, the robot sets the route so that it repeatedly cleans the bars along the preset path, avoiding missing any areas.

[0005] However, over time, trash racks can accumulate oxides on their surfaces that are difficult to remove. Underwater cleaning equipment requires multiple uses of water jets, which is not only time-consuming but also significantly reduces cleaning efficiency when cleaning multiple trash racks. Utility Model Content

[0012] As a preferred solution of the adjustment assembly of the present invention, the movable frame is L-shaped, a sliding column is connected to the bottom of the movable frame, and a steel brush with an arc-shaped shape is installed at the bottom of the movable frame.

[0013] As a preferred solution of the adjustment assembly of the present invention, the bottom of the sliding column is slidably connected to the inner wall of the limiting groove, and the top of the sliding column is slidably connected to the inner wall of the inclined groove.

[0014] The beneficial effects of the utility model are as follows: when cleaning the trash rack, high-pressure water flow is injected into the connecting pipe, so that the steel brush, the connecting pipe and the rotating nozzle rotate simultaneously to jointly clean the debris and oxides on the trash rack, thereby improving the speed of cleaning the oxides on the trash rack;

[0015] At the same time, the rotating disk can be rotated to move the steel brush away from the rotating frame, thereby expanding the cleaning range of the steel brush and further accelerating the cleaning speed and efficiency of the trash rack.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1

[0037] Reference Figures 1 to 5 , which is the first embodiment of the present utility model, provides an adjustment component that can effectively clean oxides on the trash rack.

[0038] Specifically, the cleaning unit 100 includes a rotating frame 101, a connecting pipe 102 connected to the inner wall of the rotating frame 101, a rotating nozzle 103 arranged on one side of the connecting pipe 102, a connecting frame 104 rotatably connected to the top of the connecting pipe 102, a rotating disk 106 arranged on the top of the rotating frame 101, a limiting groove 107 opened on the top of the rotating frame 101 and a movable frame 109 arranged at the bottom of the rotating disk 106, wherein the rotating nozzles 103 are arranged on both sides of the bottom of the connecting pipe 102, and they are combined into a Y shape, and a water seal bearing is provided on the top of the connecting pipe 102, and the water seal bearing is placed at the bottom of the connecting frame 104, so that the connecting pipe 102 and the rotating nozzle 103 can rotate at the bottom of the connecting frame 104;

[0039] It should be noted that when the connecting frame 104 is connected to the water pipeline, water can be injected into the connecting pipe 102. Since the connecting pipe 102 and the rotating nozzle 103 are rotatable, when the high-pressure water flow enters the connecting pipe 102 and the rotating nozzle 103, the connecting pipe 102 and the rotating nozzle 103 will rotate under the power of the water flow. Here, when the connecting pipe 102 and the rotating nozzle 103 rotate, they will drive the rotating frame 101 to rotate.

[0040] It should be noted that the internal channels of the connecting pipe 102 and the rotating nozzle 103 are interconnected. At the same time, a pipeline running through the connecting frame 104 is also provided, and this pipeline is interconnected with the connecting pipe 102.

[0041] It should be added that there are four limiting grooves 107 , which are respectively arranged on the front, back, left and right sides of the top of the rotating frame 101 , and the four limiting grooves 107 are connected to form a “+” shape;

[0042] It should also be added that there are four movable racks 109 , and the placement positions of the four movable racks 109 are the same as the limiting slots 107 , and the initial positions of the movable racks 109 are in contact with the surface of the rotating frame 101 .

[0043] It can be seen that a flange is provided on the top of the connecting frame 104, and through holes can be provided on the flange to connect bolts, so that the entire cleaning piece 100 can be installed on the underwater cleaning device through the connecting frame 104.

[0044] The rotating frame 101 is cylindrical in shape, and a plurality of through holes are opened on the outer wall of the rotating frame 101. The limiting groove 107 is a linear groove. A limiting ring 105 is provided on the top of the rotating frame 101. The shape of the limiting ring 105 is close to that of a pulley, and its cross-section is an "I" shape.

[0045] It should be added that the overall shape of the rotating frame 101 is barrel-shaped, and when the cleaning member 100 is installed on the underwater cleaning device, its opening faces downward.

[0046] The middle outer wall of the rotating disk 106 is rotatably connected to the outer wall of the limiting ring 105, the inclined groove 110 is located above the limiting groove 107, the inclined groove 110 is inclined, and an arc groove 108 is provided on the top of the rotating frame 101. The outer wall of the bolt 111 is slidably connected to the inner wall of the arc groove 108, wherein the rotating disk 106 has a disc-shaped shape, and the outer wall of the rotating disk 106 is provided with an inclined groove 110, and a bolt 111 threadedly connected to one side of the rotating disk 106, wherein a hole is provided in the middle of the rotating disk 106, which is sleeved in the middle position of the limiting ring 105. Because the cross-sectional shape of the limiting ring 105 is an "I" shape, the upper and lower sides of the limiting ring 105 will clamp the rotating disk 106, thereby supporting the rotating disk 106 above the rotating frame 101;

[0047] It should be noted that the rotating disk 106 can rotate on the limiting ring 105. When the rotating disk 106 rotates, it will drive the bolt 111 to rotate. When the rotating disk 106 rotates to a suitable position, the nut of the bolt 111 is set above the top of the rotating disk 106. When the nut is tightened, the nut will squeeze the rotating disk 106, so that the rotating disk 106 is fixed at the specified position.

[0048] The movable frame 109 is L-shaped in shape, and a sliding column 112 is connected to the bottom of the movable frame 109. A steel brush 113 with an arc-shaped shape is installed at the bottom of the movable frame 109, wherein the cross-sectional shape of the sliding column 112 is an "I" shape, and a steel wire is provided at the bottom of the steel brush 113. When the rotating frame 101 rotates, the steel brush 113 also rotates, so that when the steel brush 113 contacts the trash rack, it can quickly scrub the oxide on the trash rack, thereby speeding up the cleaning speed of the trash rack and improving the efficiency of cleaning the trash rack.

[0049] The bottom of the sliding column 112 is slidably connected to the inner wall of the limiting groove 107, and the top of the sliding column 112 is slidably connected to the inner wall of the inclined groove 110. The outer wall with a smaller diameter in the middle of the sliding column 112 is slidably connected to the limiting groove 107 and the inclined groove 110 respectively. In this way, when the rotating disk 106 rotates, the inclined groove 110 can push the sliding column 112 to move, so that the position of the steel brush 113 can be adjusted, so that the cleaning range of the steel brush 113 can be expanded, thereby speeding up the cleaning speed of the trash rack.

[0050] In summary, after the underwater cleaning device is installed with the cleaning member 100, the connecting frame 104 is connected to the high-pressure water pipe. When cleaning the trash rack, high-pressure water is injected into the connecting pipe 102, causing the rotating frame 101, the connecting pipe 102 and the rotating nozzle 103 to rotate to flush the debris and oxides on the trash rack. At this time, the steel brush 113 will also rotate to clean the oxides on the steel brush 113, thereby accelerating the cleaning speed of the trash rack and improving the efficiency of the trash rack cleaning. At the same time, by rotating the rotating disk 106, the inclined groove 110 pushes the sliding column 112 to move, so that the steel brush 113 moves away from the rotating frame 101, expanding the cleaning range of the steel brush 113 and accelerating the cleaning speed of the trash rack.

[0051] Example 2

[0052] Reference Figures 6 to 9 , which is the second embodiment of the present utility model, provides an underwater cleaning device for a trash rack, which can protect the underwater cleaning device for the trash rack from being washed away by water.

[0053] Specifically, it includes an installation component 200, including a mobile platform 201 connected to the top of the cleaning component 100, tracks 202 arranged on both sides of the mobile platform 201, an assembly part 203 connected to the top of the mobile platform, and an umbilical cable 204 and a water pipe 205 arranged on the outer wall of the same side of the mobile platform 201. Among them, the mobile platform 201 is equipped with electronic components and machinery required for the underwater cleaning device of the trash rack, and its inner wall is also equipped with a motor to drive the track wheel, and the outer cover of the track wheel is connected to the track 202. When using the underwater cleaning device of the trash rack, the operator uses a wireless remote control to wirelessly connect to the wireless communication equipment set in the mobile platform 201, so that the operator can use the wireless remote control to control the components on the underwater cleaning device of the trash rack to work.

[0054] The umbilical cable 204 is used for power transmission and control. The water pipe 205 is a high-pressure water pipe, which is used to transport high-pressure water flow to the connecting pipe 102 and the rotating nozzle 103.

[0055] The assembly 203 includes a first mounting plate 203a connected to the top of the mobile platform 201, a dehooking device 203b connected to the top of the first mounting plate 203a, and a protective cover 203c connected to the top of the dehooking device 203b. When the trash rack underwater cleaning device needs to be placed underwater for cleaning, it is necessary to protect the trash rack underwater cleaning device from being washed away by the water flow. Therefore, the dehooking device 203b is installed on the assembly 203 and can be used to connect the lifting equipment and the rope. In this way, when the trash rack underwater cleaning device is underwater, the rope will protect the trash rack underwater cleaning device from being washed away by the water flow.

[0056] It should be noted that a base for connecting to the protective cover 203c is provided at the bottom of the dehooker 203b, and a structure is provided on the two to enable the two to engage with each other. At the same time, grooves should be provided on the same side of the two. When the protective cover 203c is engaged with the base, the two grooves will be combined to form a circular hole. In this way, after the rope is tied to the dehooker 203b, the rope can pass through this circular hole and extend out of the protective cover 203c.

[0057] In summary, before placing the trash rack underwater cleaning device underwater, it is necessary to remove the protective cover 203c, then tie the rope to the unhooking device 203b, and then cover the protective cover 203c. In this way, when the trash rack underwater cleaning device is controlled by the remote control to work underwater, there will be a rope to protect it from being washed away by the water flow. When the rope needs to be removed, the protective cover 203c is removed and the rope is directly removed from the unhooking device 203b.

[0058] Example 3

[0059] Reference Figures 6 to 9 , is the third embodiment of the present utility model, which is based on the previous embodiment, except that,

[0060] A lighting assembly 300 is provided on one side of the mobile platform 201. The lighting assembly 300 includes a second mounting plate 301 connected to one side of the mobile platform 201, a camera 302 connected to the top of the second mounting plate 301, and a searchlight 303 connected to the outer wall of the second mounting plate 301. Three searchlights 303 and a camera 302 are provided on the second mounting plate 301. The camera 302 adopts a 1080P high-definition camera and is equipped with a wireless connection device inside. The wireless connection device can be connected to the pan-tilt head to transmit the picture captured by the camera 302 to other display devices in real time. When the camera 302 is shooting, the three searchlights 303 will provide sufficient light source for the camera 302.

[0061] An auxiliary cleaning assembly 400 is provided on the outer wall of the mobile platform 201. The auxiliary cleaning assembly includes a mounting groove 401 connected to the bottom of the mobile platform 201, a fixing column 402 connected to the top of the mounting groove 401, and a spray gun 403 connected to the top of the fixing column 402. When underwater, due to the large water flow resistance, the forward speed of the trash rack underwater cleaning device driven by the crawler 202 is relatively slow. At this time, the spray gun 403 can spray high-pressure water to propel the trash rack underwater cleaning device forward rapidly underwater, so that the trash rack underwater cleaning device can quickly reach the designated location for cleaning work. At the same time, when facing trash racks at different angles, the spray gun 403 can also be used to spray high-pressure water to clean the trash rack.

[0062] It should be noted that the spray gun 403 here is also connected to the water pipe 205, and a corresponding electric gate valve is provided on the water pipe 205, which is used to control the water output of the spray gun 403 and the rotating nozzle 103.

[0063] In summary, when working underwater, the underwater environment is photographed by the camera 302 on the mobile platform 201, and the image is fed back to the display device on the shore. At this time, the operator can start the spray gun 403 according to needs, so that the spray gun 403 sprays high-pressure water to push the trash rack underwater cleaning device forward quickly underwater, so that the trash rack underwater cleaning device can quickly reach the designated location for cleaning work.
