The filtering component includes a filtering box and a floating plate assembled at the bottom of the filtering box. A crushing motor is installed in the utility model. When the staff puts the water pump connecting pipe and the silt extraction cover into the water, the silt extraction cover drives the water pump connecting pipe to sink to the bottom of the water. The aperture of the filter mesh installed inside the silt extraction cover can provide space for the silt to enter and can block larger impurities. The crushing motor installed inside the silt extraction cover drives the connecting rod installed at the output end to rotate. The rotation of the connecting rod drives the crushing blade and the feeder installed outside to rotate. When the water pump draws the silt into the pipeline, the crushing blade can break up the silt. After breaking up, the feeder assists the water pump to extract the silt. The crushing blade cooperates with the feeder to prevent the pipeline from being blocked due to dense silt, thereby affecting the normal working process.

[0004] In the above-mentioned prior art, the dredging equipment is sent to the bottom of the water area for dredging by means of suspension. However, there is an undercurrent at the bottom of the water area, which makes it difficult to place the suspended equipment to the designated location, resulting in the problem of inaccurate dredging position.

[0025] The following will be combined with the drawings in 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 in 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.

[0026] See also Figure 1-6 A desilting and remediation device for water conservancy construction includes a transmission device 1 and a diving device 2. The transmission device 1 transmits the diving device 2 to the bottom of the water and is connected to the diving device 2 through an extraction device to clean the silt. The transmission device 1 includes a connecting support frame 101, which is installed on a ship or a floating object. A limiting sleeve 102 is installed at the end of the connecting support frame 101, and a power gear box 103 is installed at the connection between the connecting support frame 101 and the limiting sleeve 102;

[0027] The diving device 2 includes a diving tube 201, the outer surface of which is provided with a rack groove 202, which is engaged with the power gear box 103 and is driven up and down by the power gear box 103. The bottom of the diving tube 201 is fixedly connected with a limit tube 204, and the bottom of the limit tube 204 is fixedly connected with a bell mouth 205 to increase the dredging area. A rotatable silt-releasing impeller 206 is installed at the bottom of the bell mouth 205. A connecting joint 207 is provided at the top of the diving tube 201, and the connecting joint 207 is connected to a hose or a hard pipe, and the hose or the hard pipe is connected to an extraction device to extract silt.

[0028] Through the above technical solution, a connecting support frame 101 is set to support the limiting casing 102, and the power gear box 103 cooperates with the rack groove 202 to drive the submersible pipe 201 to rise and fall, so that the bottom of the submersible pipe 201 penetrates into the water bottom and contacts the silt, and then the extraction device and the connecting joint 207 are respectively connected through the connecting pipe to enable the bell mouth 205 at the bottom of the submersible pipe 201 to extract the silt. Because the submersible pipe 201 is a hard pipe and is lifted and lowered vertically, it can be accurately positioned, thereby achieving the effect of accurate dredging.

[0029] Specifically, the power gearbox 103 includes a power device 1031 for transmitting power. The power device 1031 is transmission-connected with a transmission worm 1032 . The transmission worm 1032 is meshed with a transmission gear 1033 . The transmission gear 1033 extends to the interior of the limiting sleeve 102 and meshes with the rack groove 202 .

[0030] Through the above technical solution, the power equipment 1031 is used to drive the transmission worm 1032 to transmit the transmission gear 1033, so that the angle of the transmission gear 1033 can be limited by the self-locking characteristics of the transmission worm 1032, thereby achieving the accuracy of the lifting and lowering of the submersible tube 201 and avoiding the submersible tube 201 driving the transmission gear 1033 to rotate under the action of gravity.

[0031] Specifically, the inner wall of the limiting sleeve 102 is fixedly connected with the limiting strip 105 , the outer surface of the diving tube 201 is provided with a limiting groove 203 , and the limiting strip 105 is plugged into the limiting groove 203 .

[0032] Through the above technical solution, the limit bar 105 is used to further limit the diving tube 201, so as to prevent the diving tube 201 from rotating during the lifting process, which may cause the transmission gear 1033 to be easily damaged due to tooth collision.

[0033] Specifically, a pipe release opening 104 is opened on the top of the limiting sleeve 102 , and the pipe release opening 104 occupies half of the diameter of the limiting sleeve 102 .

[0034] Through the above technical solution, the pipe outlet 104 is opened to facilitate the connection of the hard pipe. When the water level is deep, the single submersible pipe 201 cannot deliver the bell mouth 205 to the location of the silt. Therefore, it is necessary to connect the hard pipe at the location of the connecting joint 207 for extension. The hard pipe is connected to the connecting joint 207 by bolts, and then the extraction device is connected behind the hard pipe, so that the bell mouth 205 can penetrate into the silt location.

[0035] Specifically, the structure of the hard pipe is the same as that of the submersible pipe 201 , and a rack groove 202 and a limit groove 203 are also formed on the outer surface of the hard pipe.

[0036] Through the above technical solution, the style of the hard pipe is set so that the hard pipe can cooperate with the transmission gear 1033 and the limiting strip 105 like the diving pipe 201, thereby realizing the limiting and lifting of the hard pipe.

[0037] Specifically, the silt-releasing impeller 206 includes a connecting ring 2061, the inner wall of which is fixedly connected with an impeller blade 2062, the connecting ring 2061 is limited by the inner wall of the bell mouth 205, and the impeller blade 2062 protrudes from the bottom of the bell mouth 205, the impeller blade 2062 is a bevel blade, and the impeller blade 2062 is driven by the water flow.

[0038] Through the above technical solution, the connecting ring 2061 is used to connect with the inner bottom of the bell mouth 205 to achieve the purpose of limiting and rotating, and the impeller blades 2062 are used to break up the silt. When the water flows through the gap between the impeller blades 2062, the water pressure will push the impeller blades 2062 to cause the entire silt loosening impeller 206 to rotate.

[0039] When in use, the limiting sleeve 102 is supported by setting a connecting support frame 101, and the power gear box 103 cooperates with the rack groove 202 to drive the submersible pipe 201 to rise and fall, so that the bottom of the submersible pipe 201 penetrates into the water bottom and contacts the silt, and then the extraction device and the connecting joint 207 are respectively connected through the connecting pipe to make the bell mouth 205 at the bottom of the submersible pipe 201 extract the silt. Because the submersible pipe 201 is a hard pipe and is lifted and lowered vertically, it can be accurately positioned, achieving the effect of accurate dredging;

[0040] By installing a rotatable silt-loosening impeller 206 at the inner bottom of the bell mouth 205, when the extraction equipment extracts silt, the water flow will drive the silt-loosening impeller 206 to rotate, thereby breaking up the extracted silt and preventing the agglomerated silt from clogging the inside of the submersible pipe 201. The rotating silt-loosening impeller 206 can also break up the silt on the bottom of the water, thereby achieving the effect of preventing the inside of the submersible pipe 201 from being blocked.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
