Abstract
Description
Technical Field
[0001] The utility model relates to the field of dredging tools, in particular to a floor drain dredging device. Background Art
[0002] Offshore oil platforms produce outdoors. To timely drain the deck sewage generated during the rainy season, each deck is designed with supporting floor drain openings and sewage pipelines. The branch sewer pipelines of each floor drain are all connected and finally converge to the main floor drain sewer network for discharging to the sea. During daily production and life, sundries such as sediment and rust slag often fall onto the deck surface. During rainy days or deck cleaning operations, sewage flows into the floor drain. Since the aperture of the floor drain filter is relatively large, it cannot effectively filter some fine sediment, and the branch pipelines of the floor drain water are long, small in size, and have many corners. Long-term accumulation of dirt easily causes blockage of the floor drain pipelines. If multiple floor drains on a single deck are blocked and cannot be cleaned, the floor drains in the entire area of that deck will not be able to achieve normal drainage function, and the accumulated water is difficult to drain. Long-term accumulation of water easily corrodes the platform deck surface and equipment skids. The conventional method to solve the problem of floor drain blockage is to connect a hose to the outlet of the public water pipeline, insert the hose into the floor drain opening, and flush and dredge the floor drain with public fresh water. This method has the following defects in practical applications:
[0003] (1) It is difficult to adapt the flushing hose to the floor drain diameter, the seal is not tight, and it cannot provide sufficient flushing pressure, so it cannot effectively dredge the floor drain with a high degree of blockage, and can only play a certain role in the floor drain with less serious blockage.
[0004] (2) The flushing direction is single, and it cannot generate positive and negative forces on some stubborn blockages, so it cannot loosen and fall off the blockages, and the dredging effect on the blockages with strong adhesion to the pipe wall is poor.
[0005] (3) The operation is inconvenient, and there are certain risks in the operation. The flushing hose cannot be effectively fixed at the floor drain opening. If the flushing water flow or air flow is too large, it is easy to cause the hose to rebound and injure people. Summary of the Utility Model

In particular, it can avoid the problem of deep water accumulation on the deck caused by poor drainage of the floor drain on rainy days.
[0029] In some embodiments, the floor drain dredging device includes a pipe body 10. A joint 20 is provided at the axial first end of the pipe body 10, and the joint 20 is used to connect to a fresh water supply system or a common gas supply system; a nozzle 30 is provided at the axial second end of the pipe body 10, and the inner cavity of the nozzle 30 is in communication with the inner cavity of the pipe body 10. A control valve 40 is provided on the pipe body 10, and the control valve 40 is arranged close to the joint 20.
[0030] A handle 50 is further provided on the outer periphery of the pipe body 10, and the handle 50 is arranged close to the axial first end of the pipe body 10. A sealing assembly 60 is further provided on the outer periphery of the pipe body 10, and the sealing assembly 60 is arranged close to the axial second end of the pipe body 10.
[0031] In some embodiments, the pipe body 10 has a hollow structure. The pipe body 10 can be in a circular tubular shape. The pipe body 10 may include a plurality of connecting pipes 11 that are detachably connected. The plurality of connecting pipes 11 can be connected by threads. For example, an external thread is provided on the outer periphery of one end of a connecting pipe 11, and an internal thread is provided in the inner cavity of one end of another connecting pipe 11, and the two are threadedly connected and fixed. Alternatively, adjacent two connecting pipes 11 are connected by a threaded sleeve 12. Of course, the pipe body 10 can also be an integral structure. Preferably, the pipe body 10 can be selected as a hollow steel pipe. The hollow steel pipe is made of stainless steel, a 1 / 2-inch pipeline, and the length can be 1000 mm. The pipe body 10 serves as a common gas / water medium flow-through channel. Of course, the structure, size, and material of the pipe body 10 can be selected and set according to actual needs, and no specific limitation is made here.
[0032] In some embodiments, the joint 20 can be a threaded quick joint made of stainless steel. The joint 20 is used to connect a fresh water supply system or a common gas supply system to supply gas or water into the pipe body 10.
[0033] In some embodiments, the nozzle 30 may include a housing 31. The housing 31 is generally in a frustum shape. The housing 31 can be threadedly connected and fixed to the pipe body 10, and the inner cavity of the housing 31 is communicated with the inner cavity of the pipe body 10. A plurality of nozzle parts 32 are arranged at intervals on the housing 31, and the nozzle parts 32 are communicated with the inner cavity of the housing 31. The outlet of the nozzle part 32 is in a strip shape. The nozzle part 32 can be generally in a flat structure. The outlet of the nozzle part 32 is in a strip shape or a flat shape, which can increase the impact pressure of the common gas or water outlet. Preferably, the medium flow-through pipe of the nozzle part 32 can also be in a tapered or flat shape, which can increase the impact pressure. Preferably, the number of the nozzle parts 32 can be two, three, or any other number, and no specific limitation is made here.
[0034] In some other embodiments, the end of the second axial end of the pipe body 10 can form a medium outlet. Of course, the end of the second axial end of the pipe body 10 can be a closed structure, and it can be flushed by the nozzle 30.
[0035] In some embodiments, the control valve 40 can be selected to be made of stainless steel. Further, the control valve 40 includes a ball valve. Specifically, for example, the control valve 40 can be selected to adopt a 1 / 2-inch ball valve, which is used to control the flow direction of common gas / water into the pipe body 10.
[0036] In some embodiments, the handle 50 includes two columnar portions 51. The two columnar portions 51 are fixed to the outer periphery of the tube body 10 and are coaxially arranged. The handle 50 facilitates the staff to hold and operate. The columnar portion 51 can be generally cylindrical, or can also be a square columnar or prismatic structure. The outer surface of the handle 50 can also be an anti-slip structure, which can be a pattern, texture or concave-convex structure, etc. Preferably, the handle 50 is made of stainless steel, with a length of 200 mm and a diameter of 10 mm, and is used for pushing and pulling the floor drain dredging device by hand.
[0037] In some embodiments, the sealing assembly 60 includes a first limiting member 61, a second limiting member 62 and a sealing member 63. The sealing member 63 is clamped between the first limiting member 61 and the second limiting member 62, and the peripheral edge of the sealing member 63 protrudes from the peripheral edges of the first limiting member 61 and the second limiting member 62. Both the first limiting member 61 and the second limiting member 62 can be circular ring plate-like structures, and their structures can be the same, so as to reduce the manufacturing cost and improve the installation error tolerance rate. The first limiting member 61 and the second limiting member 62 can be fixedly connected to the tube body 10 by threading. For example, both the first limiting member 61 and the second limiting member 62 have through holes with internal threads to be fixedly connected to the external threads of the tube body 10. Alternatively, the tube body 10 is provided with a limiting convex portion. After the sealing assembly 60 is installed on the tube body 10, the nozzle 30 can cooperate with the limiting convex portion to clamp the sealing assembly 60, and the relative fixation of the sealing assembly 60 can also be achieved.
[0038] The sealing member 63 can be a circular ring plate-like structure, and the outer diameter of the sealing member 63 can be larger than the outer diameters of the first limiting member 61 and the second limiting member 62. Further, both the first limiting member 61 and the second limiting member 62 are metal parts, such as stainless steel parts, and the sealing member 63 is a rubber part, such as an anti-aging rubber pad.
[0039] It can be understood that the sealing assembly 60 is composed of the first limiting member 61, the second limiting member 62 and the sealing member 63. In terms of structural layout, the sealing member 63 (which can be a rubber pad) is in the middle, and has a certain interference fit with the inner diameter of the floor drain pipeline, which can effectively play a sealing role. The first limiting member 61 and the second limiting member 62 are sized to match the inner diameter of the floor drain and are arranged on both sides of the sealing member 63 to increase the structural strength of the sealing device.
[0040] As Figure 3 and Figure 4 shown, in some embodiments, the floor drain dredging device further includes an adjusting and supporting assembly 70, and the adjusting and supporting assembly 70 is arranged on the part of the tube body 10 between the handle 50 and the sealing assembly 60.
[0041] In some embodiments, the adjustment and support assembly 70 can be located in the inner cavity of the floor drain and abuts against the inner wall of the floor drain, which can reduce the reaction force during the dredging of the floor drain with high-pressure air flow or water flow and improve the operation stability of the floor drain dredging device.
[0042] It includes a sleeve 71, and several mounting parts 72 extend from the outer periphery of the sleeve 71. The several mounting parts 72 are arranged at intervals along the circumferential direction of the sleeve 71. Further, an internal thread is provided on the inner wall of the sleeve 71, and an external thread is provided at the end of the connecting pipe 11, so that the sleeve 71 can function as a connecting piece.
[0043] When the sleeve 71 is generally in a cylindrical structure, several mounting parts 72 radially extend from the outer periphery of the sleeve 71. The number of the mounting parts 72 can be any number of two, three or more than three. Preferably, the number of the mounting parts 72 is three, and the three mounting parts 72 are evenly distributed along the circumferential direction of the sleeve 71. The adjustment and support assembly 70 further includes several support members 73 that are movably installed in the mounting parts 72. The support members 73 can include but are not limited to bolts and fixing pins. Preferably, the support members 73 can be selected as fixing pins. The outer end of the fixing pin has a triangular structure, which is convenient for manual adjustment and can increase the contact area between the fixing pin and the pipe wall of the floor drain, reducing the reaction force during the dredging of the floor drain with high-pressure air flow or water flow. Further, the mounting part 72 has a threaded groove, and the fixing pin is threadedly connected to the threaded groove to facilitate the relative length dimension between the two.
[0044] The application of the floor drain dredging device is as follows:
[0045] (1) First, select a sealing assembly 60 adapted to the inner diameter of the floor drain opening for installation. Connect the joint 20 of the floor drain dredging device to a water supply hose or a gas supply hose, then insert the second end of the pipe body 10 into the floor drain opening, open the control valve 40 to fill the floor drain with water. At this time, hold the handle 50 and push down forcefully to generate a large positive pressure between the floor drain opening and the blockage. Then quickly pull up forcefully from the squeezed state to form a negative pressure in the pipeline. The positive and negative pressures and the impact water flow generate a large pressure and thrust on the stored water and blockage in the pipeline, making the attached dirt and sediment loose and pushing the blockage out to achieve the effect of unclogging the floor drain.
[0046] (2) After repeating the pushing and pulling actions multiple times, observe the dredging effect. If the dredging effect is not good, adjust the adjustment and support assembly 70 to fit and lock the floor drain dredging device to the pipe wall of the floor drain pipeline to form a fixed support function. Then connect the joint 20 to a high-pressure gas hose and dredge by increasing the dredging pressure. At the same time, the control valve 40 can be cooperated to perform a phased opening and closing action to form an intermittent dredging air flow to promote the loosening and falling off of the dirt.
[0047] Compared with the existing conventional water pipe flushing, the floor drain dredging device of the present application has the following advantages:
[0048] 1) The floor drain dredging device is provided with a sealing component 60 to improve the sealing performance. At the same time, it increases the functions of air supply and water supply, can provide sufficient flushing pressure, and effectively dredges the blockages with strong adhesion to the inner wall of the floor drain.
[0049] 2) Optimize the flushing method. Through forward extrusion and reverse suction operations, positive and negative forces are generated on the blockage, making the blockage loose and fall off, and improving the dredging effect.
[0050] 3) Add an adjustable support component. During the pressure compensation flushing, the adjustable support 73 can be closely attached to the inner wall of the floor drain, reducing the reaction force during pressure compensation, and improving the stability and safety performance of the equipment.
[0051] When applying this floor drain dredging device, the following effects are produced:
[0052] 1) Solve the blockage problems of the deck floor drains at multiple locations (about 20 in actual operation) and the floor drains in multiple (about 3 in actual operation) equipment skids on the offshore oil platform, and realize the normal drainage function of the floor drains.
[0053] 2) Solve the problem of corrosion caused by long-term water accumulation on the deck surface and the structure of the equipment skid due to the blockage of the floor drain.
[0054] 3) Solve the blockage of the floor drain in the key equipment skid in the narrow area, resulting in water accumulation and causing the cable to be soaked in water, leading to damage to the protective layer.
[0055] 4) Save the maintenance cost of about 100,000 yuan for outsourcing the replacement of the floor drain pipeline due to the blockage of the floor drain, which has great significance for popularization.
[0056] It can be understood that the above embodiments only represent the preferred embodiments of the present invention, and the description is relatively specific and detailed. However, it should not be construed as a limitation to the scope of the patent of the present invention; it should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can also be made, which all belong to the protection scope of the present invention; therefore, all equivalent transformations and modifications made to the scope of the claims of the present invention shall fall within the scope covered by the claims of the present invention.
