Description

Technical Field

[0001] This application relates to the technical field of jet suction dredgers, and in particular to a jet suction dredger with enhanced suction capacity. Background Technology

[0002] A jet suction dredger is a vessel specifically designed to extract sediment from the bottom of rivers, lakes, or oceans. This type of vessel utilizes a combination of jet propulsion and suction to extract sediment and transport it to a designated location. The general operating principle involves using a high-pressure water pump to generate a jet of sediment from the bottom, helping to suspend the sediment. Then, a suction pump adsorbs the suspended sediment through the suction head, drawing it up and transporting it through pipelines to the appropriate location for filtration, thus removing the sediment.

[0003] However, because it is necessary to extract silt, the filtration gaps cannot be too small. When filtering larger stones, some impurities, such as seaweed and plastic bags, will be adsorbed onto the filter screen during the filtration process. These debris will clog the filter screen, thus affecting the passage of silt and water. Due to the large gaps in the filter screen, some soft seaweed may pass through the filter screen and enter the sand pump along with the silt, causing it to become entangled on the pump impeller, resulting in pump blockage and affecting the normal operation of the pump. Utility Model Content

[0004] In order to solve the problems mentioned in the background art, this application provides a jet suction dredger with enhanced suction capacity.

[0005] This application provides a jet suction dredger with enhanced suction capacity, which adopts the following technical solution: A jet suction dredger with enhanced suction capacity includes a hull, a load-bearing frame is fixedly connected to one side of the hull, a winch is fixedly connected to the upper side of the hull, a lifting cable that cooperates with the load-bearing frame is provided on the winch, a load-bearing frame is fixedly connected to one end of the lifting cable, a suction head is fixedly connected to the lower side of the load-bearing frame, and a filter frame is fixedly connected to the lower end of the suction head.

A crushing blade located inside the filter frame is fixedly connected to the upper side of the extension plate.

[0007] A high-pressure jet assembly is installed between the hull and the sand suction head, and a sand-dredging assembly is installed on one side of the sand suction head.

[0010] Optionally, a lounge is fixedly connected to the upper side of the hull, and ventilation windows are provided on both sides of the lounge.

[0013] Optionally, the inner wall of the suction head is provided with a ceramic coating.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. This utility model, by setting a filter frame, can filter larger impurities. During the filtration process, a high-power motor is started to drive the cleaning rod to rotate. The L-shaped scraper can scrape the outside of the filter frame to remove impurities such as plastic bags and aquatic plants that may be adsorbed on the outside of the filter frame. Then, the extension plate rotates inside the filter frame to cut the aquatic plants that have entered the inside through the gaps of the filter frame, making them smaller and less likely to get tangled on the pump impeller, thereby reducing the risk of pump blockage and ensuring the suction effect of silt.

[0016] 2. By setting up impellers, the cleaning rod rotates while driving multiple impellers to rotate simultaneously. The rotation of the impellers can effectively increase the power of the fluid (i.e., the mixture of water or mud and sand). When the impellers rotate, they apply force to the fluid, causing it to flow faster, thereby improving the suction and conveying capacity of the entire sand suction system and thus increasing the suction capacity.

[0022] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0023] This application discloses a jet suction dredger with enhanced suction capacity. For example... Figure 1-4 As shown, the ship includes a hull 1, and a rest room 16 is fixedly connected to the upper side of the hull 1. Ventilation windows 17 are provided on both sides of the rest room 16. The rest room 16 is convenient for operators to rest, and the ventilation windows 17 improve the comfort inside.

[0024] Please see Figure 1 and Figure 3 The inner wall of the load-bearing frame 2 is rotatably fitted with a guide rod 18. Two limiting rings 19 that cooperate with the lifting cable 4 are fixedly connected to the guide rod 18. The guide rod 18 can guide the lifting cable 4, and the limiting rings 19 can limit and protect the two sides of the lifting cable 4 to reduce the possibility of deviation.

[0025] Please see Figure 1 A detachment block 20 is fixedly connected to one side of the inner wall of the load-bearing frame 2. The detachment block 20 cooperates with the limiting ring 19 and contacts the limiting ring 19, thereby limiting the lifting cable 4 and reducing the possibility of it detaching from the detachment block 20. A load-bearing frame 2 is fixedly connected to one side of the hull 1. A winch 3 is fixedly connected to the upper side of the hull 1. A lifting cable 4 that cooperates with the load-bearing frame 2 is installed on the winch 3. A load-bearing frame 5 is fixedly connected to one end of the lifting cable 4. A suction head 6 is fixedly connected to the lower side of the load-bearing frame 5.

[0026] Please see Figure 4The inner wall of the suction head 6 is provided with a ceramic coating 21. The ceramic coating 21 not only improves wear resistance, but also provides a smooth surface, reduces friction, and thus improves the suction capacity to a certain extent. The lower end of the suction head 6 is fixedly connected to a filter frame 7. The suction head 6 itself has a high gravity and will not be affected by the high-pressure jet assembly 14 when submerged in water. A high-power motor 8 is fixedly connected to the upper side of the inner wall of the load-bearing frame 5. The output end of the high-power motor 8 is fixedly connected to a cleaning rod 9. Multiple impellers 10 that cooperate with the inner wall of the suction head 6 are fixedly connected to the cleaning rod 9. The lower end of the cleaning rod 9 is fixedly connected to an L-shaped scraper 11 that cooperates with the outer side of the filter frame 7. An extension plate 12 is fixedly connected to the cleaning rod 9. A crushing blade 13 located inside the filter frame 7 is fixedly connected to the upper side of the extension plate 12. A high-pressure jet assembly 14 is installed between the hull 1 and the suction head 6. A sand-dredging assembly 15 is installed on one side of the suction head 6.

[0027] Please see Figure 2 and Figure 3 as well as Figure 4 The high-pressure jet assembly 14 includes a high-pressure jet pump 141 fixedly connected to one side of the hull 1, a jet hose 142 fixedly connected to the output end of the high-pressure jet pump 141, a hollow ring 143 fixedly connected to the suction head 6 and cooperating with the jet hose 142, and multiple spray holes 144 opened on the lower side of the inner wall of the hollow ring 143. Water is drawn by the high-pressure jet pump 141 and then injected into the hollow ring 143 through the jet hose 142. It is then sprayed downward through the multiple spray holes 144 to disperse the mud and sand at the bottom.

[0028] Please see Figure 1 and Figure 2 The sand dredging assembly 15 includes an extraction port 151 opened on one side of the inner wall of the suction head 6, a sand dredging hose 152 fixedly connected to the inner wall of the extraction port 151, a sand dredging pump 153 fixedly connected to the upper side of the hull 1 and cooperating with the sand dredging hose 152, and a sand discharge pipe 154 fixedly connected to the output end of the sand dredging pump 153. By starting the sand dredging pump 153, suction is generated in the extraction port 151, and the mud and sand are extracted from the suction head 6, extracted from the sand dredging hose 152, and discharged through the sand dredging pump 153 and the sand discharge pipe 154.

[0029] The implementation principle of the jet suction dredger with enhanced suction capacity in this application embodiment is as follows: In use, the hull 1 is first floated on the water surface and moved to the corresponding position and fixed. Then, the lifting cable 4 is released by the winch 3. Under the action of the load-bearing frame 2, the suction head 6 sinks to a suitable position in the water. Then, the high-pressure spray pump 141 is started to inject water into the hollow ring 143 through the spray hose 142. The water is sprayed out from the spray hole 144 inside the hollow ring 143, which disperses the mud and sand at the bottom and makes it float. At the same time, the dredging pump 153 is started to generate suction inside the suction head 6 through the dredging hose 152, and the mud, sand and water are extracted and discharged to the corresponding screening position through the sand outlet pipe 154. After filtering the water and mud, the dredging action is completed.

[0030] During the sand dredging process, the filter frame 7 can filter larger stones, plastic bags, or large seaweed. Due to the suction principle, large plastic bags and seaweed may be adsorbed on the outside of the filter frame 7. By starting the high-power motor 8 to drive the cleaning rod 9 to rotate, the L-shaped scraper 11 can scrape the outside of the filter frame 7 to remove impurities such as plastic bags and seaweed that may be adsorbed on the outside of the filter frame 7. Then, through the extension plate 12 rotating inside the filter frame 7, the seaweed that enters through the gaps of the filter frame 7 can be cut accordingly, making it smaller and less likely to get tangled on the pump impeller 10, thereby reducing the risk of pump blockage and ensuring the absorption effect of the sediment.

[0031] During the rotation of the cleaning rod 9, multiple impellers 10 will also rotate simultaneously. The rotation of the impellers 10 can effectively increase the power of the fluid (i.e., the mixture of water or mud and sand). When the impellers 10 rotate, they will exert force on the fluid, causing it to flow faster, thereby increasing the suction and conveying capacity of the entire sand suction system and thus increasing the suction capacity.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
