Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] The preferred embodiment of the high-efficiency water conservancy construction dredging device provided by the utility model is as follows Figures 1 to 5 As shown: A highly efficient desilting device for water conservancy construction, comprising a vehicle body 2, a fixed box 4 is fixedly connected to one side of the top of the vehicle body 2, a drainage groove 12 running through the vehicle body 2 is provided at the middle position of the bottom end of the fixed box 4, an anti-blocking component 5 is provided inside the fixed box 4, the top of the fixed box 4 is fixedly connected to a shell 10, drainage holes 11 are provided at equal intervals on one side of the bottom end of the shell 10, a mud discharge pipe 7 is fixedly connected to the other side of the bottom end of the shell 10, a driving motor 8 is fixedly connected to the other side of the shell 10, the output end of the driving motor 8 extends to the interior of the shell 10 and is fixedly connected to a spiral extrusion rod 9 through a coupling, a sludge pump 1 is fixedly connected to the other side of the top of the vehicle body 2, the output end of the sludge pump 1 is communicated with one side of the top end of the shell 10 through a conduit, the input end of the sludge pump 1 is fixedly connected to a mud suction hood 3 through a conduit, and a filter component 13 is provided at the bottom end of the mud suction hood 3.

[0031] The anti-blocking component 5 includes a mounting seat 503, which is fixedly connected to the upper end of the inner wall of the fixed box 4 at equal intervals. The bottom end of the mounting seat 503 is fixedly connected to a waterproof electric push rod 504, and the output end of the waterproof electric push rod 504 is fixedly connected to a sliding frame 502. The top of the sliding frame 502 is fixedly connected to a top rod 501 at equal intervals. When the inside of the drainage hole 11 is accidentally blocked by a small amount of silt, the top rod 501 can be slid up and down to achieve dredging of the inside of the drainage hole 11, thereby preventing it from being accidentally blocked and affecting the efficiency of subsequent drainage of the drainage hole 11.

[0032] In this embodiment, the length of the top rod 501 is greater than the depth of the drainage hole 11, and the top rod 501 corresponds to the drainage hole 11 one by one. Using the longer and one-to-one corresponding top rod 501, it is convenient to fully clear and prevent blockage inside the drainage hole 11.

[0033] In this embodiment, sliding grooves 505 are provided on both sides of the inner wall of the fixed box 4, and sliders 506 that slide with the inside of the sliding grooves 505 are fixedly connected on both sides of one end of the sliding frame 502. The sliding of the sliders 506 in the sliding grooves 505 makes the sliding up and down sliding of the sliding frame 502 more stable.

[0034] In this embodiment, the shape of the sliding frame 502 in the top view is comb-shaped, and the top of the sliding frame 502 and the bottom of the top rod 501 are welded into an integrated structure.

[0036] Example 2

[0037] On the basis of Example 1, the preferred embodiment of the high-efficiency water conservancy construction desilting device provided by the present invention is as follows: Figures 1 to 5 As shown: the filter assembly 13 includes a slot 1302, which is opened on both sides of the bottom end of the mud suction cover 3, and the bottom end of the mud suction cover 3 is rotatably connected to a rotating block 1303 at an equal angle, the bottom end of the inside of the mud suction cover 3 is movably connected to a sieve plate 1301, and the two sides of the sieve plate 1301 are fixedly connected to a slot 1307, and the bottom end of the sieve plate 1301 is fixedly connected to a fixed block 1306 at an equal angle. The sieve plate 1301 can prevent some larger solids and other impurities in the sludge from being sucked into the mud suction cover 3 and causing damage to the sludge pump 1. At the same time, the rotating block 1303 can be engaged with the fixed block 1306, and the fixing bolt 1305 can be matched with the thread inside the bolt hole 1304 to realize the disassembly and assembly between the sieve plate 1301 and the bottom end of the mud suction cover 3, thereby facilitating the thorough cleaning or replacement of the sieve plate 1301.

[0038] In this embodiment, a locking structure is formed between the rotating block 1303 and the lower end inside the fixed block 1306, and the cross-section of the fixed block 1306 is L-shaped. The locking of the rotating block 1303 and the lower end inside the L-shaped fixed block 1306 is used to achieve preliminary locking and disassembly between the screen plate 1301 and the bottom end of the mud suction hood 3.

[0039] In this embodiment, both sides of one end of the rotating block 1303 are arc-shaped, and there are three rotating blocks 1303 distributed at equal angles. The use of the arc-shaped rotating block 1303 makes it easier for the user to use his fingers to rotate the rotating block 1303 so that it is stuck inside the fixed block 1306 or separated from it.

[0040] In this embodiment, one end of the fixed block 1306 is movably connected with a fixing bolt 1305, and one end of the rotating block 1303 is provided with a bolt hole 1304 that is threadedly matched with the fixing bolt 1305. The fixing bolt 1305 is threadedly matched with the thread inside the bolt hole 1304 to ensure that the rotating block 1303 and the inside of the fixed block 1306 are firmly engaged, thereby ensuring that the screen plate 1301 and the bottom end of the mud suction hood 3 are firmly installed.

[0041] In this embodiment, a locking structure is formed between the block 1307 and the inside of the slot 1302, and the shape of the slot 1302 and the block 1307 in the top view is convex. The locking of the convex block 1307 with the inside of the slot 1302 is used to improve the stability of the initial locking between the screen plate 1301 and the bottom end of the mud suction hood 3.

[0042] The working principle and use process of the utility model are as follows: first, the vehicle body 2 is moved to the designated operation position, and then the mud suction cover 3 is placed inside the sludge, and then the sludge pump 1 is started to suck the sludge through the mud suction cover 3. At this time, the sieve plate 1301 can be used to prevent some larger solid impurities in the sludge from being sucked into the mud suction cover 3 and causing damage to the sludge pump 1, thereby extending its service life;

[0043] After that, the initially filtered sludge enters the interior of the housing 10. At this time, the driving motor 8 is started to drive the spiral extrusion rod 9 to rotate, thereby spirally extruding the sludge, so that the squeezed water enters the interior of the fixed box 4 through the drainage hole 11, and is then guided by the inclined guide plate 6 to be discharged faster and more thoroughly through the drainage groove 12. The mud cake produced by the spiral extrusion rod 9 can be discharged through the mud discharge pipe 7, realizing automatic solid-liquid separation of the sludge, avoiding the cumbersome and inconvenient traditional method of stopping the machine to clean the sludge, and improving the efficiency of dredging;

[0044] At the same time, when the drain hole 11 is accidentally clogged by a small amount of silt, the waterproof electric push rod 504 can be activated to drive the sliding frame 502 to rise, thereby causing the top rod 501 to rise and insert into the drain hole 11. After that, the waterproof electric push rod 504 drives the sliding frame 502 to descend, so that the top rod 501 is completely separated from the drain hole 11, thereby achieving dredging of the drain hole 11, avoiding accidental blockage and affecting the subsequent drainage efficiency of the drain hole 11;

[0045] The fixing bolt 1305 can be rotated by a tool such as a screwdriver until it is completely disengaged from the inside of the bolt hole 1304, and then the corresponding rotating block 1303 can be rotated until it is completely disengaged from the inside of the fixed block 1306. After that, the screen plate 1301 can be removed from the bottom end of the mud suction hood 3, which facilitates the thorough cleaning or replacement of the screen plate 1301.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
