[0022] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 6 As shown in the figure, the present invention provides a dredging device for water conservancy construction, including a body 1, an output end 2, a connecting pipe 3, and a conveying hose 4. The output end 2 is fixedly connected to the lower right side of the body 1 and communicates with the body 1. The connecting pipe 3 is fixedly connected to the right end of the output end 2 and communicates with the output end 2. The conveying hose 4 is sleeved on the upper end of the connecting pipe 3 and is movably connected to the connecting pipe 3. A connecting device 5 is provided on the upper end of the connecting pipe 3. The connecting device 5 is fixedly connected to the connecting pipe 3.

[0024] refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 A sealing groove 6 is provided on the upper circumference of the connecting pipe 3.

[0025] The above solution involves creating a sealing groove 6 around the upper circumference of the connecting pipe 3. This groove 6 works in conjunction with the clamping ring 542 and the rubber sealing gasket 543 to compress the conveying hose 4 into the sealing groove 6 when clamping it, thereby enhancing the sealing effect.

[0026] refer to Figure 1 , Figure 2 and Figure 3The connecting device 5 includes a box body 51, a spacer ring 52, a movable groove 53, a clamping assembly 54, a linkage assembly 55, and a control assembly 56.

The linkage assembly 55 is sleeved on the outside of the four clamping assemblies 54. The control assembly 56 is located at the upper right side inside the box body 51.

[0027] The above solution involves setting a connecting device 5 to fix the conveying hose 4, connecting and fixing the conveying hose 4 to the surface of the connecting pipe 3. This facilitates the quick connection and disassembly of the conveying hose 4 and improves the efficiency of connection and fixing.

[0028] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The clamping assembly 54 includes a pressure block 541, a clamping ring 542, a rubber sealing gasket 543, and a tension spring 544. The pressure block 541 is disposed inside the movable groove 53, and its left and right ends extend out of the movable groove 53 and are slidably connected to it. The clamping ring 542 is fixedly connected to the left side of the pressure block 541, and the rubber sealing gasket 543 is fixedly connected to the left side surface of the clamping ring 542. The rubber sealing gasket 543 and the clamping ring 542 are both corresponding to and adapted to the sealing groove 6. There are two tension springs 544, which are respectively disposed at the front and rear ends of the right side of the clamping ring 542. The left and right ends of the two tension springs 544 are fixedly connected to the right surface of the clamping ring 542 and the right inner wall of the spacer ring 52, respectively.

[0029] The above solution is adopted: by setting up a clamping component 54, the delivery hose 4 is clamped and fixed to the surface of the connecting pipe 3, and the delivery hose 4 is clamped and squeezed into the sealing groove 6, thereby fixing and sealing.

[0030] refer to Figure 2 , Figure 3 and Figure 4 The linkage component 55 includes a rotating ring 551, a rotating block 552, and a toothed ring 553. The rotating ring 551 is located inside and outside the box body 51 and is rotatably connected to the box body 51. There are four rotating blocks 552, which are evenly and fixedly connected to the inner wall of the rotating ring 551. The positions of the four rotating blocks 552 and the four pressing blocks 541 correspond to each other and are compatible. The toothed ring 553 is fixedly connected to the upper surface of the rotating ring 551.

[0031] The above solution is adopted: by setting up a linkage component 55, it is used to drive the clamping component 54, and has the function of simultaneously linking four clamping components 54 for clamping.

[0032] refer to Figure 1 , Figure 2 and Figure 3 The control component 56 includes a motor 561, an output shaft 562, and a gear 563. The motor 561 is fixedly connected to the right side of the upper surface of the housing 51. The output shaft 562 is fixedly connected to the output end 2 of the motor 561. The lower end of the output shaft 562 extends into the housing 51 and is rotatably connected to the housing 51. The gear 563 is sleeved on the lower end surface of the output shaft 562 and is fixedly connected to the output shaft 562. The gear 563 meshes with the gear ring 553.

[0033] The above scheme is adopted: by setting up a control component 56, it is used to drive and control the linkage component 55, and has the function of driving the linkage component 55 to rotate to link the four clamping components 54.

[0034] refer to Figure 3 , Figure 4 and Figure 5 Limiting blocks 7 are fixedly connected to the upper and lower surfaces of the pressure block 541, and the two limiting blocks 7 are slidably connected to the movable groove 53.

[0035] The above solution is adopted: by fixing limit blocks 7 on the upper and lower surfaces of the pressure block 541 respectively, which cooperate with the movable groove 53 to limit the pressure block 541 and ensure the stable movement of the clamping assembly 54.

[0036] The working principle of this utility model:

[0037] During connection and fixing, the conveying hose 4 is inserted from the upper end of the connecting pipe 3 until it reaches the bottom of the box 51. At this time, the conveying hose 4 will wrap around the sealing groove 6. Then, the motor 561 is controlled to drive the output shaft 562 to rotate. The rotation of the output shaft 562 drives the gear 563 to rotate. The rotation of the gear 563 drives the gear ring 553 that meshes with it to rotate. The rotation of the gear ring 553 drives the rotating ring 551 to rotate. The rotation of the rotating ring 551 drives the four rotating blocks 552 to rotate. When the rotating blocks 552 rotate to the right end of the pressure block 541... During compression, the upper end of the pressure block 541 is pressed into the movable groove 53 and moves towards the connecting pipe 3. At the same time, the limiting block 7 moves within the movable groove 53 to limit the movement and ensure stability. The movement of the pressure block 541 causes the clamping ring 542 to move towards the connecting pipe 3. As the clamping ring 542 moves, it stretches the tension spring 544. Simultaneously, the clamping ring 542 drives the rubber sealing gasket 543 to clamp and compress the conveying hose 4, squeezing the conveying hose 4 into the sealing groove 6. The inner wall of the sealing groove 6 clamps and fixes the conveying hose 4, thereby completing the fixation and sealing.

[0038] When the connection is subsequently released, the control motor 561 drives the output shaft 562 to rotate in the opposite direction. The reverse rotation of the output shaft 562 drives the gear ring 553 to rotate in the opposite direction through the engagement of the gear 563 and the gear ring 553. At the same time, the gear ring 553 drives the rotating ring 551 to rotate. The rotation of the rotating ring 551 drives the four rotating blocks 552 to rotate, so that the rotating blocks 552 rotate away from the position of the pressure block 541, so that the pressure block 541 is no longer squeezed by the rotating blocks 552. At this time, the tension spring 544 will rebound, pulling the clamping ring 542 outward, so that the clamping ring 542 drives the rubber sealing gasket 543 to release the clamping and squeezing of the delivery hose 4, thereby releasing the fixation. Then, the delivery hose 4 can be pulled upward from the surface of the connecting pipe 3 to release the connection fixation.

[0039] In summary, this dredging device for water conservancy construction, through the coordinated use of a body 1, output end 2, connecting pipe 3, conveying hose 4, connecting device 5, box 51, spacer ring 52, movable groove 53, clamping assembly 54, pressure block 541, clamping ring 542, rubber sealing gasket 543, tension spring 544, linkage assembly 55, rotating ring 551, rotating block 552, gear ring 553, control assembly 56, motor 561, output shaft 562, gear 563, sealing groove 6, and limit block 7, improves or solves to a certain extent the problem of existing dredging pumps using a method of tightening bolts to connect and fix the conveying hose to the connecting pipe. This method requires external tools to repeatedly tighten and disassemble the bolts, which is not only time-consuming and labor-intensive but also affects work efficiency.
