For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The following will further describe the embodiments of the present utility model in detail with reference to the drawings:

[0027] Please refer to Figures 1-7 ​The utility model provides an embodiment: an in-situ passivation and repair device for riverbed mud, comprising a repair shell 10, the interior of the repair shell 10 is hollow, which is convenient for storing substances used for the passivation and repair of riverbed mud, including chemical passivation: adding chemical agents, such as lime, iron salts, aluminum salts, phosphates, etc., which can form insoluble precipitates with heavy metals, thereby reducing their bioavailability and mobility; using materials such as polymers, clay minerals or activated carbon to adsorb organic pollutants to reduce their re-release into the water body; and microbial passivation: introducing specific microorganisms or microbial enzymes, which can degrade organic pollutants in the mud, such as petroleum hydrocarbons and PAHs, and a hose 11 is fixedly connected to the feed inlet on the upper end surface of the repair shell 10, and the repaired substance is transported into the repair shell 10 from the outside through the hose 11, and a repair pipe 19 is fixedly installed at the discharge port at the bottom of the repair shell 10, and the repair pipe 19 is inserted into the The repair tube 19 is inserted into the bottom mud of the river channel, and the repair material is discharged from the repair tube 19 to act on the inside of the bottom mud to passivate and repair the bottom mud. When the repair tube 19 is inserted into the bottom mud of the river channel, it may be unstable due to the action of the river channel water flow. Therefore, a fixed ring plate 16 is fixedly sleeved on the outer end face of the repair shell 10, and notches 20 are evenly distributed at the outer end edge of the fixed ring plate 16. A fixed column 18 is respectively arranged in each of the notches 20, and a strip chute 17 is provided through each of the fixed columns 18. A cylindrical portion 21 is fixedly installed between the side walls of each of the notches 20, and the cylindrical portion 21 passes through the corresponding strip chute 17. An annular water cylinder 13 is slidably installed on the outer ring end face of the repair shell 10, and a raised ring strip 23 is fixedly arranged on the lower end face of the annular water cylinder 13. A groove 22 is respectively arranged on the upper end face of each of the fixed columns 18, and the raised ring strip 23 is slidably embedded in the groove 22;

[0028] When the repair pipe 19 is inserted into the bottom mud, the surrounding fixing columns 18 are also inserted into the bottom mud to fix the repair shell 10. At the same time, water can be added to the inner cavity of the annular water cylinder 13 through the water pipe 12 connected to the upper end of the annular water cylinder 13, so that the counterweight of the annular water cylinder 13 becomes heavier, thereby pressing the fixing columns 18 to be inserted downward into the bottom mud again, so that the stability of the repair shell 10 is better, and it can effectively cope with water flows with different flow rates.

[0029] It should be noted that, for the convenience of taking out the device from the sediment in the later stage, in this embodiment, a protruding ring part is provided on the annular water cylinder 13. The lower end surface of the protruding ring part is equidistantly provided with water bag parts 14 corresponding to the fixed columns 18. Each water bag part 14 is fixedly connected to the outer side end surface of the corresponding fixed column 18. A corrugated part 15 is provided on the outer side surface of the water bag part 14. The inner cavity of the water bag part 14 is communicated with the annular water cylinder 13. The whole water bag part 14 is attached to the outer side end surface of the fixed column 18. Once water is injected into the annular water cylinder 13, the water will fill into each water bag part 14, so that the water bag part 14 bulges. The bulging water bag part 14 can greatly improve the friction with the sediment by using the corrugated part 15 on the surface layer, thereby further improving the stability during passivation repair. After the repair is completed, only the water in the annular water cylinder 13 needs to be pumped out, and the water bag part 14 will naturally deflate, so that a cavity appears between the fixed column 18 and the sediment, which is convenient for pulling out.

[0030] During specific implementation, the repair housing 10 is placed in the river channel, so that the repair pipe 19 is inserted into the sediment, and the surrounding fixed columns 18 are also inserted into the sediment to fix the repair housing 10. At the same time, water can be added to the inner cavity of the annular water cylinder 13 through the water pipe 12 communicated with the upper end of the annular water cylinder 13, so that the weight of the annular water cylinder 13 becomes heavier, thereby pressing the fixed column 18 to insert deeper into the sediment again, making the stability of the repair housing 10 better and effectively coping with water flows of different velocities. Once water is injected into the annular water cylinder 13, the water will fill into each water bag part 14, so that the water bag part 14 bulges. The bulging water bag part 14 can greatly improve the friction with the sediment by using the corrugated part 15 on the surface layer, thereby further improving the stability during passivation repair. When the repair substance is transported into the repair housing 10 through the hose 11 from the outside, a repair pipe 19 is fixedly installed at the discharge port at the bottom of the repair housing 10. The repair pipe 19 is inserted into the sediment of the river channel, and the repair substance is discharged from the repair pipe 19 and acts on the inside of the sediment to perform passivation repair on the sediment. After the repair is completed, only the water in the annular water cylinder 13 needs to be pumped out, and the water bag part 14 will naturally deflate, so that a cavity appears between the fixed column 18 and the sediment, which is convenient for pulling out.

[0031] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manners. Any other implementation manners obtained by those skilled in the art according to the technical solutions of the present invention also belong to the scope of protection of the present invention.
