Description

Technical Field

[0001] The utility model relates to the technical field of waterway environmental protection dredging construction, in particular to a drainage device for inland river mud barges. Background Art

[0002] In the construction of waterway dredging, it is usually necessary to use a mud barge to transport the cleared earth and rocks to a temporary dock, and then use a long-arm excavator to landfill the earth and rocks. However, the dredged soil excavated into the mud barge by equipment such as backhoes usually contains a large amount of water, which not only occupies the limited mud barge space, reduces transportation efficiency and increases costs; moreover, the dredged soil is mixed with water in the mud barge for a long time, which increases the water content of the dredged soil, reduces the efficiency of landing the dredged soil and drying and dehydration, and increases the project cost. Therefore, the drainage device plays an important role in the cleaning work of the mud barge.

[0003] The current mud barge drainage device can separate the water in the silt from the solidified silt under the power of pumping, thereby achieving effective drainage of the silt, reducing the number of silt transportation times, and improving transportation efficiency.

[0004] For example, the Chinese patent with the authorization announcement number CN218492599U discloses a sludge drainage device for a mud barge, which belongs to the technical field of dredging construction. The sludge drainage device includes a water filter assembly, a pumping device and a diversion pipe; the water filter assembly is placed in the sludge storage space of the mud barge, and is used to filter the water in the sludge, including a pipe network, a filter pipe, a filter membrane and an outlet pipe; there are multiple filter pipes, the upper ends of which are connected to the same side of the pipe network and communicated with the pipe network, the lower ends of which are closed to be immersed in the sludge, and the outer periphery of each filter pipe is provided with a plurality of water-permeable holes; the filter membrane is arranged one by one with the filter pipe, and the filter membrane is wrapped around the outer periphery of the filter pipe with the water-permeable holes; one end of the outlet pipe is connected to the pipe network and communicated with the pipe network; the pumping device is connected to the end of the outlet pipe away from the pipe network; one end of the diversion pipe is connected to the pumping device, and the other end extends out of the mud barge to discharge the water pumped out by the pumping device. The sludge drainage device can be widely applied to existing mud barges, without the need to modify the mud barge, and has high drainage efficiency.

[0005] Although the above-mentioned silt drainage device proposes a method of using drainage pipes densely distributed in the mud barge compartment and then draining the water in the mud barge compartment through pumping equipment, which is of certain significance for reducing the water content of the silt in the mud barge, the dense drainage pipes in the compartment will affect the efficiency of subsequent dredged soil landing and are not suitable for this type of construction process. Therefore, the study of a mud barge rapid drainage device is of great significance to the rapid development of waterway dredging projects. Utility Model Content

[0028] The mud barge storage cabin in the embodiment of the utility model is the working equipment of the drainage device. The mud barge at the bottom of the storage cabin can be pumped into the mud-water separator by the pumping device 4 in the drainage device to separate the mud and water. The two roller steel water baffles 1 are arranged in parallel inside the mud barge cabin, so that the unfiltered mud barge can be stored in the middle of the two steel water baffles 1. By the arrangement of the anti-filter screen 101 and the drainage hole 102 on the steel water baffle 1, the mud barge can be firstly filtered, and then the existing sludge pumping technology can be applied. The pump body on the pumping device 4 can pump the filtered mud barge into the pumping pipe 5, and it can be transported to the discharge position through the pumping pipe 5. The use of the conveying seat facilitates the convenient collection or discharge of the discharged water.

[0029] like Figures 1 to 5 As shown, two steel water retaining plates 1 are vertically arranged inside the mud barge storage cabin, and the steel water retaining plates 1 are in contact with the inner wall of the mud barge storage cabin, so that the two steel water retaining plates 1 and the inner wall of the mud barge storage cabin form a sealed space for primary drainage of the drainage device.

[0030] Furthermore, the number of the drainage holes 102 is a plurality of groups, and the plurality of groups of drainage holes 102 are arranged in an array.

[0031] By using the side fixing block 3, it is convenient to set the anti-filter 101 on the steel water retaining plate 1. Furthermore, the side fixing block 3 includes a fitting block 301 arranged on both sides of the anti-filter 101, and the middle of the two fitting blocks 301 is penetrated by the same tightening bolt 302, and the tightening bolt 302 is penetrated by the steel water retaining plate 1 and the anti-filter 101.
