[0021] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-7As shown, a device for automatic silting of a sedimentation tank comprises a retractable silting box provided at the bottom of a sedimentation tank 6, wherein the front side of the retractable silting box is connected to a traction device, and the two sides of the top are each connected to a lifting device, and the retractable silting box comprises a lower metal trough 1 and an upper metal trough 2 slidably connected thereto, the front end of the lower metal trough 1 is detachably connected to the first connecting member 9 of the traction device, the top of the lower metal trough 1 is detachably connected to the second connecting member 13 of one of the lifting devices, and the top of the upper metal trough 2 is detachably connected to the second connecting member 13 of the other lifting device.

[0023] Preferably, if Figures 1 to 4 As shown, the inner surface of the lower metal trough 1 is provided with a spring hook 5, and the surface of the upper metal trough 2 is provided with a positioning hole 4 that cooperates with the spring hook 5. Through the cooperation process of the spring hook 5 and the positioning hole 4, after determining the appropriate telescopic silt removal box according to the size of the bottom surface of the sedimentation tank 6, the corresponding spring hook 5 and positioning hole 4 are selected for snap-fitting, so that the length of the telescopic silt removal box can be adapted to different sedimentation tanks 6.

[0024] Preferably, the lower metal trough 1 is composed of a bottom plate and side plates on both sides to form a U-shaped trough structure, and the upper metal trough 2 is composed of a bottom plate, side plates on both sides and a rear plate at the rear end to form a U-shaped trough structure with a closed rear end.

[0025] Preferably, if Figure 2 As shown, the upper metal trough 2 is provided with a guide rail on its side, and the lower metal trough 1 is provided with a guide groove on its side that is slidably connected to the guide rail. The cooperation between the guide rail and the guide groove makes the sliding process between the upper metal trough 2 and the lower metal trough 1 smoother. At the same time, during the raising and lowering process of the upper metal trough 2 and the lower metal trough 1, the guide rail can limit the guide groove, preventing the upper metal trough 2 and the lower metal trough 1 from relative displacement in the vertical direction.

[0026] Preferably, a pulley mechanism 3 is provided at the bottom of the lower metal trough 1 and the bottom of the upper metal trough 2. By providing the pulley mechanism 3, the friction force of the upper metal trough 2 and the lower metal trough 1 moving on the surface of the sedimentation tank 6 can be reduced.

[0027] Preferably, if Figure 5 As shown, the traction device includes a traction winch 7 , and the rope on the winch wheel of the traction winch 7 passes around a fixed pulley 8 provided on the side wall of the sedimentation tank 6 and is connected to a first connecting member 9 .

[0028] More preferably, the first connecting member 9 is an electromagnet structure that magnetically engages with the first connecting iron plate 1.1 fixed to the front end of the lower metal trough 1. When the first connecting member 9 is an electromagnet structure, the magnetic force of the first connecting member 9 can be controlled to be turned on and off. When turned on, the first connecting member 9 can be magnetically attracted to the first connecting iron plate 1.1 at the front end of the lower metal trough 1. In this way, after the entire telescopic silt cleaning box is adjusted to the desired length and placed at the bottom of the sedimentation tank 6, the traction winch 7 is activated to rotate its winch wheel, driving the rope to pull the first connecting member 9 to move, and the telescopic silt cleaning box scrapes the silt, thereby collecting the silt at the bottom of the sedimentation tank 6 into the telescopic silt cleaning box.

[0029] Preferably, if Figure 6 and 7 As shown, the lifting device includes four steel columns 10 fixedly arranged on the top of the sedimentation tank 6. The top of the steel column 10 is fixedly connected to the steel plate 12. A lifting winch 11 is provided on the steel plate 12. The rope of the lifting winch 11 is connected to the second connecting member 13.

[0030] More preferably, the second connecting member 13 is an electromagnet structure, wherein one second connecting member 13 is magnetically matched with the second connecting iron plate 1.2 fixed to the top of the lower metal slot 1, and the other second connecting member 13 is magnetically matched with the third connecting iron plate 2.1 fixed to the top of the upper metal slot 2. When the second connecting member 13 is an electromagnet structure, the magnetic force of the second connecting member 13 can be controlled to be turned on and off. After being turned on, one of the second connecting members 13 can be magnetically attracted to the second connecting iron plate 1.2 fixed to the top of the lower metal trough 1, and the other second connecting member 13 can be magnetically attracted to the third connecting iron plate 2.1 fixed to the top of the upper metal trough 2; by starting the two lifting winches 11, the winch wheel can be rotated, driving the rope to pull the second connecting member 13 upward, so that the entire telescopic dredging box rises and leaves the water surface. After reaching a certain height, one of the lifting winches 11 is stopped, and the other lifting winch 11 continues to work, so that the entire telescopic dredging box can be tilted, thereby pouring the silt into the pre-prepared silt receiving tray.

[0031] The working principle of this embodiment is as follows:

[0032] Before desilting the sedimentation tank 6, the spring buckle 5 and the positioning hole 4 are matched to determine the appropriate retractable desilting box according to the size of the bottom surface of the sedimentation tank 6. Then, the corresponding spring buckle 5 and the positioning hole 4 are selected for snap-fitting, so that the length of the retractable desilting box can be adapted to different sedimentation tanks 6. By controlling the magnetic force of the first connecting member 9 to be turned on, the first connecting member 9 can be magnetically adsorbed to the first connecting iron plate 1.1 at the front end of the lower metal trough 1. In this way, when the entire retractable desilting box is adjusted to a good length and placed at the bottom of the sedimentation tank 6, the traction winch 7 is started to rotate the winch wheel, driving the rope to pull the first connecting member 9 to move, and the retractable desilting box scrapes the silt, thereby collecting the silt at the bottom of the sedimentation tank 6 into the retractable desilting box. By controlling the magnetic force of the first connecting member 9 to be turned off, the first connecting member 9 can be magnetically disconnected from the first connecting iron plate 1.1 at the front end of the lower metal trough 1. By controlling the magnetic force of the second connecting member 13 to activate, one of the second connecting members 13 can be magnetically attached to the second connecting iron plate 1.2 fixed to the top of the lower metal trough 1, and the other second connecting member 13 can be magnetically attached to the third connecting iron plate 2.1 fixed to the top of the upper metal trough 2. By activating the two lifting winches 11, the winch wheels can be rotated, driving the rope to pull the second connecting member 13 upward, thereby raising the entire telescopic dredging box out of the water surface. After reaching a certain height, one lifting winch 11 is stopped, while the other lifting winch 11 continues to operate, causing the entire telescopic dredging box to tilt, thereby pouring the silt into a pre-prepared silt receiving tray. Finally, the entire telescopic dredging box is removed from the second connecting member 13, cleaned, and returned to its original position at the bottom of the sedimentation tank 6, awaiting the next desilting operation.

The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. Equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
