Abstract
Description
Technical Field
[0001] This utility model belongs to the field of robotic arm technology, specifically relating to a robotic arm for dredging water diversion channels. Background Technology
[0002] Siltation in canals has increasingly affected their normal functioning in flood control, drainage, irrigation, and water supply. In order to restore the normal function of canals and promote the rapid and sustainable development of the economy and society, canal dredging and desilting projects are being carried out to make the river deeper and wider, the water clearer, and the production conditions and living environment of the people significantly improved.
[0003] The robotic arms commonly used for dredging channels are equipped with buckets at their front ends. However, during operation, the robotic arms cannot determine the depth to which the buckets will be lowered. This can easily damage the channel bed during dredging, leading to soil erosion and affecting the channel's usability in subsequent use. Utility Model Content
[0004] The purpose of this invention is to provide a robotic arm for dredging water diversion channels, which can avoid damage to the channel bed and solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a robotic arm for dredging water diversion channels, comprising a robotic arm body and a dredging cover, wherein the dredging cover is disposed at one end of the robotic arm body, and a detection component is disposed at the bottom of the dredging cover, wherein there are several detection components, which are equidistantly distributed around the axis of the dredging cover, and a dredging component is disposed at the top of the robotic arm body, wherein the bottom end of the dredging component extends through the top of the dredging cover to the bottom of the inner side of the dredging cover.
[0006] Furthermore, a mounting flange is fixedly connected to the bottom end of the outer wall of the sludge removal cover.
[0007] Furthermore, the detection assembly includes a cylinder fixedly connected to the top of the mounting flange, the top of the cylinder being closed, a sliding column being slidably connected to the bottom of the cylinder, a pressure sensor being fixedly connected to the top of the cylinder, and a standard spring being provided between the pressure sensor and the sliding column, with the two ends of the standard spring being fixedly connected to the bottom end of the pressure sensor and the top end of the sliding column, respectively.
[0008] Furthermore, a base plate is fixedly connected to the bottom end of the sliding column.
[0009] Furthermore, the dredging assembly includes a conveying cylinder fixedly connected to the top of the dredging hood, the bottom end of the conveying cylinder extending to the bottom of the inner side of the dredging hood, and a spiral rod rotatably connected inside the conveying cylinder.
[0010] Furthermore, a geared motor is fixedly connected to the top of the conveying cylinder, and the output shaft of the geared motor is fixedly connected to one end of the screw rod.
[0011] Furthermore, a discharge pipe is fixedly connected to the top of the side wall of the conveying cylinder.
[0012] Compared with the prior art, the beneficial effects of this utility model are: the dredging cover is sent to the bottom of the channel by the robotic arm body, and the detection component detects whether the bottom of the dredging cover has reached the bottom of the channel. When the dredging cover reaches the bottom of the channel, the dredging component pumps out the silt, which achieves the effect of dredging and can avoid damage to the channel bed.

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0020] like Figure 1 and 2 As shown, a robotic arm for dredging a water diversion channel includes a robotic arm body 1 and a dredging cover 2. The dredging cover 2 is located at one end of the robotic arm body 1. A detection component 3 is located at the bottom of the dredging cover 2. There are several detection components 3, which are equidistantly distributed around the axis of the dredging cover 2. A dredging component 4 is located at the top of the robotic arm body 1. The bottom end of the dredging component 4 extends through the top of the dredging cover 2 to the bottom of the inner side of the dredging cover 2.
[0021] According to the above structure, during use, the sludge removal cover 2 is sent to the bottom of the channel by the robotic arm body 1, and the detection component 3 detects whether the bottom of the sludge removal cover 2 has reached the bottom of the channel. When the sludge removal cover 2 reaches the bottom of the channel, the sludge is pumped out by the sludge removal component 4 to achieve the effect of sludge removal.
[0022] like Figure 3 and 4 As shown, an installation flange 21 is fixedly connected to the bottom of the outer wall of the sludge hood 2.
[0023] Based on the above structure, the mounting flange 21 is designed to facilitate the installation of the detection component 3.
[0024] like Figure 3 and 4 As shown, the detection component 3 includes a cylinder 31 fixedly connected to the top of the mounting flange 21. The top of the cylinder 31 is closed, and a sliding column 32 is slidably connected to the bottom of the cylinder 31. A pressure sensor 35 is fixedly connected to the top of the cylinder 31. A standard spring 34 is provided between the pressure sensor 35 and the sliding column 32. The two ends of the standard spring 34 are fixedly connected to the bottom end of the pressure sensor 35 and the top end of the sliding column 32, respectively. A base plate 33 is fixedly connected to the bottom end of the sliding column 32.
[0025] According to the above structure, during use, the sludge removal cover 2 is lowered to the bottom of the channel by the robotic arm body 1. When the bottom of the sludge removal cover 2 is still in the silt layer, the support force provided by the silt is small, so the retraction of the bottom plate 33 and the sliding column 32 is small. After the bottom plate 33 passes through the silt layer and touches the bottom, the bottom of the channel generates a large support force on the bottom plate 33, so that the bottom plate 33 and the sliding column 32 continue to retract. At this time, the standard spring 34 is compressed. When the top of the bottom plate 33 contacts the bottom of the mounting flange 21, the standard spring 34 is compressed to a certain length. At this time, the pressure of the standard spring 34 on the pressure sensor 35 corresponds to the length of the standard spring 34 retraction. The pressure sensor 35 is electrically connected to the external controller. By the pressure value reflected by the pressure sensor 35, it can be determined that the bottom of the mounting flange 21 has reached the bottom of the silt layer, which is convenient for sludge removal without damaging the bottom of the channel.
[0026] like Figure 3 and 4 As shown, the dredging assembly 4 includes a conveying cylinder 41 fixedly connected to the top of the dredging cover 2. The bottom end of the conveying cylinder 41 extends to the bottom of the inner side of the dredging cover 2. A screw rod 42 is rotatably connected inside the conveying cylinder 41. A reduction motor 43 is fixedly connected to the top of the conveying cylinder 41. The output shaft of the reduction motor 43 is fixedly connected to one end of the screw rod 42. A discharge pipe 44 is fixedly connected to the top of the side wall of the conveying cylinder 41.
[0027] According to the above structure, when the bottom end of the mounting flange 21 reaches the bottom end of the sludge layer, the screw rod 42 is rotated by starting the reduction motor 43, thereby conveying the sludge inside the sludge hood 2 upward. When the sludge reaches the top of the conveying cylinder 41, it flows downward along the discharge pipe 44. In actual use, a pipe can be connected to one end of the discharge pipe 44 to discharge the sludge in a directional manner.
[0028] The working principle of this utility model is as follows: During use, the sludge removal cover 2 is lowered to the bottom of the channel by the robotic arm body 1. When the bottom of the sludge removal cover 2 is still in the silt layer, the supporting force provided by the silt is small, so the retraction of the bottom plate 33 and the sliding column 32 is small. After the bottom plate 33 passes through the silt layer and touches the bottom, the bottom of the channel generates a large supporting force on the bottom plate 33, thereby causing the bottom plate 33 and the sliding column 32 to continuously retract. At this time, the standard spring 34 is compressed. When the top of the bottom plate 33 contacts the bottom of the mounting flange 21, the standard spring 34 is compressed to a certain length. At this time, the pressure of the standard spring 34 on the pressure sensor 35 is equal to that of the standard spring 34. The pressure sensor 35 is electrically connected to the controller of the external device according to the length of the spring 34 retraction. The pressure value reflected by the pressure sensor 35 can be used to determine that the bottom end of the mounting flange 21 has reached the bottom end of the silt layer, which is convenient for sludge removal without damaging the bottom end of the channel. When the bottom end of the mounting flange 21 reaches the bottom end of the silt layer, the screw rod 42 is rotated by starting the reduction motor 43, thereby conveying the silt inside the sludge removal hood 2 upward. When the silt reaches the top of the conveying cylinder 41, it flows downward along the discharge pipe 44. In actual use, a pipe can be connected to one end of the discharge pipe 44 to discharge the silt in a directional manner.
[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
