Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure water jet dredging pumps, in particular to a support structure for a high-pressure water jet dredging pump group of a dredging ship. Background Art

[0002] Dredging pumps play an important role in many engineering projects, such as the maintenance and widening of ports and waterways, as well as the construction and maintenance of water conservancy facilities; the design and use of these pumps have greatly improved the efficiency and effect of dredging projects. Modern dredging pumps can not only cope with various complex underwater terrains and soil conditions, but also meet environmental protection requirements and reduce the negative impact on the environment; dredging pumps can eject water flow at high pressure through their internal pressurization mechanism and hydraulic design, combined with a fine control system, for cutting or removing underwater soil layers.

[0003] The prior art patent CN220185382U discloses an offshore engineering dredging pump, which includes a pump body, a pump chamber connector, a support seat, moving rollers, a vacuum generator, and an external pipeline. The top of the pump body is fixedly connected to one side of the pump chamber connector by clamping. The top of the support seat is threadedly connected to one end of the pump body. The top of the moving roller is fixedly connected to the bottom surface of the support seat. The input end of the vacuum generator is fixedly connected to one side of the external pipeline. A disassembly component is also provided at the connection between the pump chamber connector and the pump body. The disassembly component includes a fixed frame, an electric cylinder, a push rod, and a limit disc. The middle part of the limit disc is clamped to the output end of the pump body. The fixed frame is fixedly connected to the top surface of the pump body. The output end of the electric cylinder is fixedly connected to one end of the push rod. The outside of the push rod is fixedly connected to the surface of the limit disc. A jack matching the output end of the pump body is also provided inside the limit disc. A sealing pad is adhesively connected to the outside of the jack. A connecting pipe and a flange are also provided on the opposite side of the vacuum generator and the pump body. There are two groups of electric cylinders. During use, the external pipeline can be placed at the siltation area, and then the flange is used to screw the output end of the pump body and the connecting pipe to the flange in pairs through bolts and complete the fixation. During the suction process, the vacuum generator uses a nozzle to eject compressed air at high speed to form a jet flow at the nozzle outlet, generating entrainment flow; under the entrainment effect, the air around the nozzle outlet is continuously sucked away; the positive pressure air source in the use environment is processed through a series of reactions to obtain negative pressure, so as to suck the silt into the pump body. Under the pressurization of the pump body, the silt can be ejected from the outer nozzle of the pump chamber connector, thereby increasing the jet lift of the pump body and improving the silt suction effect.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where like or similar reference numerals denote like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0020] Please refer to Figures 1 to 5 , the present utility model provides a support structure for a high-pressure water jet dredging pump set of a dredging ship, which includes two fixing mechanisms, a bracket 1 and a support platform 2. The fixing mechanism includes a screw 3 and a connecting plate 4. One end of the screw 3 is provided with a limit ring 5, and the other end of the screw 3 is provided with a rotating disk 6. Both ends of the connecting plate 4 are provided with fixing rods 7, and the middle of the connecting plate 4 has a threaded groove 8. A connecting platform 9 is provided below the bracket 1, and a fixing platform 10 is provided below the support platform 2. Both sides of the support platform 2 have limit grooves 11. The two fixing rods 7 are respectively inserted into the connecting platform 9 and are located on both sides of the connecting platform 9, and also penetrate through the support platform 2. The screw 3 is threadedly connected to the connecting plate 4 and is located in the threaded groove 8. The screw 3 is also rotatably connected to the corresponding support platform 2 and is located on both sides of the support platform 2, and the limit ring 5 is located in the limit groove 11. The connecting platform 9 is slidably connected to the support platform 2 and is located inside the support platform 2. The support structure of this design is connected to the dredging ship by welding the fixing platform 10, and then the bracket 1 can be easily fixed under the action of the fixing mechanism, thereby forming a structure that can support the dredging pump. Moreover, this structure can also facilitate the subsequent disassembly of the dredging pump, thus improving the practicability.

[0021] Wherein, two buffer pads 12 are provided at one end of the support platform 2. The two buffer pads 12 respectively abut against the bracket 1 and are located at one end of the bracket 1. The buffer pads 12 can facilitate buffering the vibration generated during the operation of the dredging pump, thereby avoiding the impact of the dredging pump.

[0022] Secondly, two cushion plates 13 are provided between the support platform 2 and the fixing platform 10. A convex platform 14 is provided below the support platform 2, and the convex platform 14 is fixedly connected to the fixing platform 10 by bolts and is located inside the fixing platform 10. The cushion plates 13 can facilitate improving the buffering degree between the convex platform 14 and the fixing platform 10, thereby playing a role in protecting the dredging pump.

[0023] Again, the high-pressure water jet dredging pump group support structure of the dredging ship further includes a reinforcement mechanism. The reinforcement mechanism includes a holding block 15 and two sliding rods 16. A spring 17 is arranged on the sliding rod 16. The holding block 15 is slidably connected to the corresponding sliding rod 16, sleeved on the two sliding rods 16, and the spring 17 abuts against one end face of the holding block 15. The two sliding rods 16 are respectively fixedly connected to the support platform 2 and are located at the other end of the support platform 2.

[0024] Two holding pads 18 are arranged on the other end face of the holding block 15. The two holding pads 18 respectively abut against the bracket 1 and are located at the other end of the bracket 1. Through the continuous abutment of the spring 17, the holding block 15 can easily push the holding pad 18 to abut against the bracket 1, thereby improving the stability of the bracket 1 and further ensuring the stability of the dredging pump.

[0025] When using the present utility model to install the dredging pump, first weld the fixed platform 10 to the dredging ship, then slidably arrange the support platform 2 on the fixed platform 10, and at the same time connect the convex platform 14 to the fixed platform 10 through bolts. It should be noted that at this time, the bracket 1 and the dredging pump group have been welded into one body. Then lift the dredging pump group by a crane so that the bracket 1 is installed on the support platform 2, the connecting platform 9 enters the support platform 2, and then rotate the screw 3 clockwise. Under the action of the thread groove 8, the connecting plate 4 moves towards the support platform 2, and the two fixing rods 7 are inserted into the connecting platform 9, thereby completing the fixation of the dredging pump group. In this way, the technical problem that when the dredging pump is applied to the dredging ship, since it was not originally designed for the dredging ship, its original fixing structure cannot be used is solved.

[0026] What is disclosed above is only a preferred embodiment of the present utility model. Of course, it cannot be used to limit the scope of the rights of the present utility model. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present utility model still fall within the scope covered by the utility model.
