Description

Technical Field

[0001] The utility model belongs to the technical field of offshore platform dredging tools, in particular to a low-pressure dredging tool for floor drains. Background Art

[0002] The deck drain of the offshore platform is used to collect rainwater and various equipment to discharge liquids such as dirty oil sludge. The deck drain is an open design. In daily production work, it is inevitable that impurities enter the pipeline through the open floor drain, causing pipeline blockage and causing trouble to daily production work. When the liquid entering the floor drain pipeline does not flow smoothly and there is a slight blockage in the floor drain pipeline, the existing bendable spring dredger is generally used for unblocking. However, the length of the bendable spring is limited and it is impossible to effectively dredge the deep part of the pipeline. Long-term blockage can easily lead to more and more serious blockage in the deep part of the pipeline, and eventually form a serious blockage. When the blockage is serious, it is necessary to entrust professionals to use special equipment to dredge the floor drain pipeline, which is not only time-consuming and labor-intensive, but also increases the production operation cost. Utility Model Content

[0003] In view of this, the utility model aims to provide a low-pressure floor drain dredging tool, which is easy to operate and can effectively solve the problem of dredging slight blockages in floor drain pipelines on offshore platform decks.

[0005] Furthermore, a gasket is sleeved on the lower end of the hollow screw, and the gasket is arranged between the lower end of the hollow screw and the rubber plug.

[0006] Furthermore, a gasket is sleeved on the upper end of the hollow screw, and the gasket is arranged between the nut and the rubber plug.

[0007] Furthermore, the gasket is a rubber gasket.

[0008] Furthermore, the hollow screw is a hollow structure, a hexagonal flange structure is arranged at its lower end, and a thread structure is arranged at its upper end.

[0009] Furthermore, the main body of the rubber stopper is a truncated cone structure, and the radius length of the upper bottom surface of the truncated cone structure is greater than the radius length of the lower bottom surface.

[0010] Compared with the prior art, the low-pressure floor drain dredging tool described in the utility model has the following advantages:

[0020] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0022] like Figure 1-Figure 3As shown, the utility model is a low-pressure dredging tool for floor drains, which uses a rubber plug 3 with a truncated cone structure to seal the open floor drain, a hollow screw is inserted into the middle of the truncated cone, and a nut 4 and a gasket 2 are combined to seal the space between the screw and the truncated cone. The top can be connected to an external pressure water source, so as to achieve the purpose of dredging the slightly blocked floor drain pipeline. Specifically, it includes a hollow screw 1, a rubber plug 3, a nut 4 and a joint 5, and a through hole is provided at the axial center position of the rubber plug 3. The hollow screw 1 is inserted in the through hole, that is, one end of the hollow screw 1 passes through the through hole from the lower end of the rubber plug 3, and then is connected to the nut 4 and the joint 5 which are sequentially arranged at the upper end of the rubber plug 3. In actual application, the joint 5 can be provided with specifications of different sizes so that rubber hoses 6 of different sizes can be connected accordingly, and the rubber hose 6 is an existing basis. The lower end of the hollow screw 1 is sleeved with a gasket 2, and the gasket 2 is arranged between the lower end of the hollow screw 1 and the rubber plug 3; the upper end of the hollow screw 1 is sleeved with a gasket 2, and the gasket 2 is arranged between the nut 4 and the rubber plug 3. The combination of the gasket 2 and the nut 4 can seal the space between the hollow screw 1 and the rubber plug 3 when tightened. Preferably, the gasket 2 is a rubber gasket. In the description of the present utility model, it should be understood that the terms "center", "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0023] The hollow screw 1 is a hollow structure, with a hexagonal flange structure at its lower end and a thread structure at its upper end. When the hollow screw 1 is connected to the rubber stopper 3, the flange structure at the lower end of the hollow screw 1 will stay outside the rubber stopper 3 and cannot enter the through hole of the rubber stopper 3.

[0024] The main part of the rubber stopper 3 is a truncated cone structure, and the radius length of the upper bottom surface of the truncated cone structure is greater than the radius length of the lower bottom surface. In other words, the main part of the rubber stopper 3 is like an inverted cone structure, except that the top part of the inverted cone is cut off, leaving a truncated cone structure. This structure can not only ensure that the rubber stopper 3 is suitable for floor drains of different calibers, but also ensure that the rubber stopper 3 and the open end of the floor drain can be effectively compressed and sealed.

[0025] In the actual working process, the operator places the gasket 2 on the end of the hollow screw 1 provided with the flange structure, then passes the hollow screw 1 through the rubber plug 3, and then places the gasket 2 and the nut 4 in sequence, and tightens the nut 4 to seal the space between the hollow screw 1 and the rubber plug 3. According to the actual working needs, the operator selects a connector 5 of a suitable size to connect the rubber hose 6 of a suitable size, and uses the connector 5 of a suitable size to connect to the external thread end of the hollow screw 1 and tighten it. After the assembly is completed, Figure 2 As shown. Figure 3 As shown, put the floor drain open and press it, connect the external low-pressure water source through the rubber hose 6, and the slightly blocked floor drain pipeline can be dredged. The offshore platform floor drain pipeline mainly adopts a 150-pound low-pressure pipeline. The dredging tool described in the present invention uses geothermal water or production sewage as the working pressure energy source, and the water pressure is maintained below 1.6MPa. No high-pressure power equipment is required, and the blocked floor drain can be dredged by the operator independently, and geothermal water or production sewage is the existing basis. Through water pressure impact and forming a channel at the blockage, the pipeline solidification and viscous soft blocking material are continuously flushed with high-velocity water flow, and the blockage is dredged to the open discharge tank, which is the existing basis. Because the continuous water flow can cover the entire pipeline, it can then realize the unblocking of the floor drain network and the floor drain extending longer, and the blockage distance is less limited, which is obvious compared to the traditional "ground rat" tool dredging advantage.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
