[0003] The above equipment can play a role in mixing the bottom mud and the medicine to a certain extent. However, the water outlet pipe is arranged on the right side of the rotating column. When the electric push rod pulls the rotating column to move to the left and rotates, the water outlet pipe sprays the medicine on the right side of the rotating column, which is not enough to make the medicine better penetrate into the bottom mud for mixing, thereby affecting the overall repair effect. Therefore, a stirring mechanism for in-situ repair of contaminated bottom mud is needed. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The contaminated sediment in-situ remediation stirring mechanism is one of the devices used to treat sediment pollution in water bodies. This mechanism is used to stir and treat sediment at the bottom of the water body to promote the reaction between pollutants in the sediment and chemical substances in the water body, thereby reducing water pollution and achieving treatment effects.

[0025] The existing equipment can fully mix the bottom mud and the medicine. However, the water outlet is set on the right side of the rotating column. When the electric push rod pulls the rotating column to move to the left and rotates, the water outlet sprays the medicine on the right side of the rotating column, which is not enough to effectively mix the bottom mud with the sprayed medicine, thus affecting the overall repair effect. Figure 1-Figure 4 , provides a stirring mechanism for in-situ remediation of contaminated sediment, including a bracket 1 and a top plate 2 fixed on the top of the bracket 1, and a medicine tank 3 is fixedly connected to the top of the top plate 2.

[0026] refer to Figure 2-Figure 4As shown, the effectiveness of sludge treatment depends largely on the contact area between the sludge and the medicine. At this time, the fixed stirring range of the stirring rod 4 will limit the contact area between the sludge and the medicine, resulting in the failure of the sludge to be effectively treated. In order to improve the repair effect, the following settings are made: a stirring rod 4 is arranged at the bottom of the top plate 2, and a stirring mechanism 5 is arranged at the bottom of the top plate 2 for driving the stirring rod 4 to move back and forth vertically and rotate forward and reversely to fully mix the medicine and the sludge. The stirring mechanism 5 includes a conversion head 52 and a rotary drum 53 rotatably connected to the bottom of the conversion head 52. The threads on the surface of the rotary drum 53 are threads of a specific angle, and the spacing between the threads is large. The bottom of the top plate 2 A cylinder 51 is provided, and a conversion head 52 is fixed on the telescopic end of the cylinder 51. The outer wall of the rotary drum 53 is threadedly connected with a vortex driver 54. The cylinder 51 is started to make the telescopic end drive the stirring rod 4 to move down and be placed on the bottom of the water. After being placed on the bottom of the water, the cylinder 51 pulls and pushes the stirring rod 4 back and forth vertically in a small range, so that the stirring rod 4 is threadedly connected with the vortex driver 54 through the rotary drum 53, so that the rotary drum 53 drives the stirring rod 4 to reciprocate vertically and rotate forward and backward to contact the bottom mud. In the process of riverbed mud treatment and repair, the vertical reciprocating and forward and reverse rotation of the stirring rod 4 can help to fully mix the bottom mud and the medicine, stir the bottom mud from the bottom into the water body, make it fully contact with the medicine, and ensure that the medicine can cover the entire area of ​​the bottom mud.

[0027] refer to Figure 3-Figure 4As shown, the spraying direction determines the contact area and mixing degree between the medicine and the bottom mud. However, the spraying direction of the medicine in the existing equipment is not enough to fully combine with the bottom mud, so that the pollutants in the bottom mud will continue to exist in the area not covered by the medicine, resulting in that some areas of the bottom mud cannot be effectively treated, and the pollutants continue to be released into the water body, thereby affecting the overall repair effect. In order to improve the effectiveness of the medicine covering the bottom mud, the following settings are made: a medicine supply mechanism 6 for spraying medicine on the bottom mud is provided at the bottom of the top plate 2, and the medicine supply mechanism 6 includes a medicine pump 61 fixed at the bottom of the top plate 2, the medicine pumping end of the medicine pump 61 is fixedly connected to the inside of the medicine tank 3, and the medicine outlet end of the medicine pump 61 is fixedly connected to a hose 62, and the end of the hose 62 away from the medicine outlet end of the medicine pump 61 is fixedly connected to the inside of the conversion head 52, and the stirring The stirring rod 4 is fixedly connected to the bottom end of the rotary drum 53, and a plurality of spray nozzles 63 are fixedly connected to the circumference of the stirring rod 4. The medicine extraction pump 61 is started to extract the medicine in the medicine tank 3, and the medicine is transmitted in sequence through the hose 62 to the conversion head 52-rotor 53-stirring rod 4 until it is sprayed out through the plurality of spray nozzles 63. When the stirring rod 4 moves downward and rotates forward, the medicine sprayed by the plurality of spray nozzles 63 at the bottom of the stirring rod 4 will impact the bottom mud, causing the bottom cement to float upward. During the floating process, the plurality of spray nozzles 63 on both sides of the stirring rod 4 are also spraying medicine, further strengthening the combination of the bottom mud and the medicine. While the floating bottom mud continues to float upward under the influence of buoyancy, the upward movement and reversal of the stirring rod 4 and the continuous spraying of the medicine can effectively spray the medicine to every corner and deep layer of the bottom mud, so that the bottom mud as a whole can be effectively treated.

[0028] refer to Figure 1As shown, a displacement mechanism 7 for driving the stirring mechanism 5 to move back and forth laterally is provided at the bottom of the top plate 2. The displacement mechanism 7 includes a mounting frame 71 fixed inside the bracket 1. An electric slide rail 72 is fixedly connected inside the mounting frame 71. A moving block 73 is slidably connected on the surface of the electric slide rail 72. The moving block 73 is slidably sleeved inside the mounting frame 71. The cylinder 51 is fixedly connected to the bottom of the moving block 73. Starting the electric slide rail 72 can cause the moving block 73 to move back and forth laterally, thereby driving the moving block 73 and the bottom stirring mechanism 5 to achieve large-scale stirring. Two chute grooves 8 are symmetrically arranged vertically on the opposite side of the bracket 1. A telescopic cylinder 82 is slidably connected inside the chute 8. A telescopic rod 81 is slidably sleeved inside the telescopic cylinder 82. One end of the telescopic rod 81 away from the telescopic cylinder 82 is fixedly connected to the circumference of the conversion head 52. When the conversion head 52 moves back and forth horizontally, the telescopic rod 81 on its side can be placed in or out of the telescopic cylinder 82 according to the displacement situation. At the same time, the telescopic cylinder 82 can be synchronously displaced according to the up and down movement of the stirring rod 4, thereby stabilizing the conversion head 52. Two telescopic cylinders 9 are symmetrically fixedly connected on the opposite side of the bracket 1. A telescopic rod 91 is slidably sleeved inside the two telescopic cylinders 9. One end of the telescopic rod 91 away from the telescopic cylinder 9 is fixedly connected to the circumference of the rotary drive 54. When the rotary drive 54 moves back and forth horizontally, the telescopic rod 91 on its side can be placed in or out of the telescopic cylinder 9 according to the displacement situation, thereby stabilizing the rotary drive 54.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
