Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline dredging mechanisms, in particular to a device for indoor pipeline dredging. Background Technique
[0002] Buildings including residential buildings, office buildings, etc. will be installed with sewage pipes, etc., and the wastewater generated in areas such as bathrooms and kitchens will be discharged into the sewage tank in time by gravity. When the sewage pipe is attached with discharged sundries or blocked by other foreign objects (such as when washing kitchen tableware, the discharged animal grease gradually adheres to the inner wall of the pipe and the thickness gradually increases, which in turn causes the sewage discharge capacity of the pipe to become worse or even completely blocked; when there are too many foreign objects such as feces or paper in the toilet or squat toilet in the bathroom, which causes the sewage discharge capacity of the pipe to become worse or even completely blocked, etc.), it will affect the normal sewage discharge function of the sewage pipe, and even completely lose its function, and the sewage will flow back into the room, resulting in dirty indoor floors, etc.
[0003] In the prior art, when the sewage pipe is blocked, the dredging personnel generally dredge it by means of a manual stirring rod device or an electric stirring rod device, etc. Specifically, the staff inserts the front end of the stirring rod (with an elastic and variable structure) into the blocked part, and then rotates the stirring rod manually or by electric drive. Then, the stirring rod separates the blocked object from the inside of the pipe, so as to achieve the purpose of dredging the blocked sewage pipe. Although the above mode realizes the dredging needs to a certain extent, due to structural limitations, there are still the following technical problems to be solved urgently. First: The manual method requires the staff to continuously stir the stirring rod. When the sewage pipe is blocked severely, due to the long dredging time, it will bring inconvenience to the staff, and it is not conducive to improving work efficiency. Moreover, when the blockage is severe, due to the relatively limited force applied manually, it cannot guarantee effective dredging of the pipe. Second: Although the electric stirring rod device does not require the staff to operate the stirring rod manually and the applied force is relatively large, which can bring convenience to the staff and achieve a good dredging effect accordingly. However, when dredging, due to the lack of water entry, the effect of the stirring rod alone in dredging the pipe is also relatively limited. More importantly, the length of the stirring rod is limited. If the blocked object is located deep in the sewage pipe, the front end of the stirring rod cannot contact the blocked object, so the dredging purpose cannot be achieved. In summary, it is particularly necessary to provide a device that can dredge the sewage pipe synchronously through compressed air and tap water. Content of the Utility Model
[0004] In order to overcome the drawbacks described in the background, which exist in the existing manual stirring rod equipment and electric stirring rod equipment for dredging indoor sewage pipes due to structural limitations, the present utility model provides an equipment for dredging indoor pipes. Through the combined action of relevant mechanisms, it can conveniently seal and connect the lower connecting pipe to the upper part of the pipe or fixture to be dredged (such as the water inlet or fecal inlet of a toilet or squat toilet, and the sewage pipe inlet) by means of expansion. By using high-pressure compressed air or a synchronous method of air and pressurized water (including hot water) output by an air compressor, the blockage can be dredged. Thus, a relatively good dredging effect can be achieved for the blockage including deep inside the pipe, which brings convenience to the staff and correspondingly improves the work efficiency.
[0005] The technical solution adopted by the present utility model to solve its technical problems is as follows:
[0006] An equipment for dredging indoor pipes, including an electric air compressor, a sleeve joint, a valve, a lower connecting pipe, and a flange. It is characterized in that it also has an expansion mechanism; there is a limiting plate on the outer side of the upper end of the lower connecting pipe, and there are openings on the side ends of the limiting plate and the flange. The flange is sleeved on the outer side end of the lower connecting pipe and is located below the limiting plate; the expansion mechanism includes a jacking pipe, a sealing plate, and an air inlet pipe. There are fixing holes on both side ends of the sealing plate, and a guiding hole on the sealing plate. The upper end of the jacking pipe is installed at the lower end of the guiding hole of the sealing plate, and the lower end of the air inlet pipe is installed at the upper end of the guiding hole of the sealing plate. The flange, the limiting plate, and the sealing plate are connected together by bolts; one end of the air inlet pipe and the two valves are respectively connected in parallel. The other end of the first valve, the other end of the second valve, the lower end of the sleeve joint, and the exhaust pipe of the air storage tank of the air compressor are respectively connected by pipes.
[0007] Further, the sleeve joint is made of rubber and has an open structure at the upper end. A self-locking clamp is installed on the outer side end of the sleeve, and a branched pipe is integrally formed at the lower end of the sleeve.
[0008] Further, the outer diameters of the flange, the limiting plate of the lower connecting pipe, and the sealing plate are the same.
[0009] Further, the inner diameter of the flange is greater than the outer diameter of the lower connecting pipe.
[0010] Further, the lower connecting pipe is made of rubber, and the flange and the expansion mechanism are made of metal.
[0011] Further, the upper and lower ends of the jacking pipe are of an open structure, and the outer diameter of the upper end of the jacking pipe is greater than that of the lower end. The outer side from the upper end to the lower end of the jacking pipe is a smoothly tapered structure.
[0012] Further, the outer diameter of the lower end of the jacking pipe is smaller than the inner diameter of the lower connecting pipe, and the outer diameter of the part above the lower end is greater than the inner diameter of the lower connecting pipe.
[0013] Furthermore, the outer diameters of the limiting plate and the sealing plate of the flange and the lower connecting pipe are larger than the outer diameter of the sewage pipe inlet, and the outer diameter of the lower connecting pipe is smaller than the inner diameter of the sewage pipe inlet.
[0014] Furthermore, there are multiple sets of the lower connecting pipes. The inner diameters of each set of lower connecting pipes are the same, and the outer diameters of each set of lower connecting pipes are different.
[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the staff needs to dredge the water inlet, the fecal inlet of the toilet or squat toilet, and the sewage pipe inlet, the staff sleeved the corresponding type of lower connecting pipe into the relevant water inlet, fecal inlet, and sewage pipe inlet, and then the staff tightened the two nuts, and the jacking pipe moved downward. Since the outer side from the upper end to the lower end of the jacking pipe is a smoothly-transitioned conical structure, in this way, due to the extrusion effect, the outer diameter of the outer end of the lower connecting pipe becomes larger from top to bottom, and it is tightly sealed and fixed together with the relevant water inlet, fecal inlet, and sewage pipe inlet. By separately controlling the two valves, the high-pressure compressed air or air and pressurized water (including hot water) output by the air compressor are in a synchronous manner to dredge the blockage. Therefore, a relatively good dredging effect can be achieved on the blockage including the deep part of the pipeline, which brings convenience to the staff and correspondingly improves the work efficiency.

[0019] Figure 1 、 2As shown in the figure, the equipment for dredging indoor pipelines includes an electric air compressor (not shown in the figure, 2KW), a sleeve joint 1, manual valves 21 and 22, a lower connecting pipe 3, a hollow flange 4, and also has an expansion mechanism; there is an integrally formed annular limiting plate 31 on the outer side of the upper end of the lower connecting pipe 3, and there is an opening 5 in the middle of both side ends of the limiting plate 31 and the flange 4. The flange 4 is sleeved on the outer side end of the lower connecting pipe 3 from top to bottom and is located below the limiting plate 31; the expansion mechanism includes a jacking pipe 61, a sealing plate 62, and an air inlet pipe 63. There is a fixing hole 64 at both side ends of the circular sealing plate 62, and there is a guiding hole 65 in the middle of the sealing plate. The upper end of the jacking pipe 61 is welded to the lower end of the guiding hole 65 of the sealing plate, and the lower end of the air inlet pipe 63 is welded to the guiding hole 65 of the sealing plate. Two bolts 7 are led out upward through the openings at both side ends of the flange 4, the openings at both side ends of the limiting plate 31, and the fixing holes 64 at both side ends of the sealing plate 62. Two nuts 8 are respectively screwed into the upper ends of the two bolts 7 to connect the expansion mechanism and the lower connecting pipe 3 together; a tee joint 9 is welded to the upper end of the air inlet pipe 63. There are two valves. The upper end and the right end of the tee joint and one end of the two valves 21 and 22 are respectively connected by threads. The other end of the first valve 21 is connected to the lower branch pipe of the sleeve joint 1 through a first hose 10 with greater strength, and the other end of the second valve 22 is connected to the exhaust pipe of the air storage tank of the air compressor through a second hose 11 with greater strength.
[0020] Figure 1 , 2 As shown in the figure, the sleeve joint 1 is made of rubber material with strength (the upper end is an open circular structure, slightly smaller than the outer diameter of the valve nozzle of the faucet). A self-locking clamp 101 (existing mature technology) is installed in the middle of the outer side end of the sleeve. There is an integrally formed branch pipe 102 (communicating with the inside of the sleeve) at the lower end of the sleeve. A metal fixing pipe is tightly sleeved on the outer side end of the branch pipe 102 (which plays a role in strengthening the strength of the branch pipe). The outer diameters of the flange 4, the limiting plate 31 on the outer side of the upper end of the lower connecting pipe, and the sealing plate 62 are the same. The inner diameter of the hollow part of the flange 4 is larger than the outer diameter of the lower connecting pipe 3. The lower connecting pipe 3 is made of rubber material, and the flange 4, the expansion mechanism, and the tee pipe 9 are made of metal material. The upper and lower ends of the jacking pipe 61 are open structures, and the outer diameter of the upper end of the jacking pipe 61 is larger than that of the lower end. The outer side from the upper end to the lower end of the jacking pipe 61 is a smoothly tapered structure. The outer diameter of the lower end of the jacking pipe 61 is smaller than the inner diameter of the lower connecting pipe 3, and the outer diameter of the part above the lower end of the jacking pipe 61 is larger than the inner diameter of the lower connecting pipe 3. The outer diameters of the flange 4 and the limiting plate 31 of the lower connecting pipe and the sealing plate 62 are larger than the outer diameters of the water inlet, the feces inlet of the toilet or squat toilet, and the sewage pipe inlet (not shown in the figure). The outer diameter of the lower connecting pipe 3 is slightly smaller than the inner diameters of the water inlet, the feces inlet of the toilet or squat toilet, and the sewage pipe inlet. There are multiple sets of lower connecting pipes 3. The inner diameters of each set of lower connecting pipes 3 are the same, and the outer diameters of each set of lower connecting pipes 3 are different and slightly smaller than the outer diameters of the water inlets, the feces inlets of different toilets or squat toilets, and the sewage pipe inlets.
[0021] Figure 1 , 2 As shown, when the present innovation needs to dredge the water inlet and the fecal inlet of a toilet or a squatting pan (the lower end is connected to the sewage pipe), and the sewage pipe inlet (such as the sewage pipe connecting the sink in the kitchen), the staff sets the lower connecting pipe 3 of the corresponding model in the relevant water inlet, fecal inlet, and sewage pipe inlet; then the staff uses a wrench to screw down two nuts 8 respectively, and the jacking pipe 61 moves downward. Since the outer side from the upper end to the lower end of the jacking pipe 61 is a smoothly tapered structure, in this way, due to the extrusion effect, the outer diameter of the lower connecting pipe 3 becomes larger from top to bottom on the inner side, and it is tightly and hermetically fixed together with the relevant water inlet, fecal inlet, and sewage pipe inlet. Then the staff sets the upper part of the sleeve joint 1 on the lower end of the water nozzle of the faucet, and uses a screwdriver to tighten the fixing bolt of the clamp 101. The clamp 101 tightly sleeves the sleeve joint 1 under the faucet (this function is optional. If it is not convenient to connect to the faucet, etc., this function can also not be used). After the staff separately opens the valve 22, the highly compressed air output by the air compressor dredges the blockage. The staff can also separately open the valve 21, and the high-pressure tap water output by the faucet dredges the blockage. If the faucet is connected to a water heater with a hot water output function, then the hot water can play a better role in melting and discharging the animal fat and the like adhering to the inner wall of the sewage pipe (the two valves can also be opened simultaneously, and the high-pressure tap water and the high-pressure air enter the sewage pipe simultaneously to flush the blockage). Specifically, the staff can first open the valve 21, close the valve 21 after the sewage pipe is filled with water, and then open the valve 22. In this way, the highly compressed air output by the air compressor and the pressurized water dredge the blockage in a synchronous manner (the staff controls the size of the valve core of the valve 22 to control the air pressure entering the sewage pipe. Since the pressure output by the air compressor is large, it can effectively flush open the blockage; the staff controls the size of the valve core of the valve 21 to control the tap water pressure entering the sewage pipe. Since the tap water also has a relatively large pressure, it can relatively effectively flush open the blockage). After the work is completed, the staff uses a wrench to loosen the two nuts 8 upward respectively, and the jacking pipe 61 moves upward. In this way, the downward extrusion effect on the lower connecting pipe 3 is reduced. After the lower end of the jacking pipe 61 is separated from the upper end of the lower connecting pipe 3, the outer diameter of the lower connecting pipe 3 becomes smaller and is no longer fixed together with the relevant water inlet, fecal inlet, and sewage pipe inlet, and the staff can take out the expansion mechanism upward. Then the staff uses a screwdriver to loosen the fixing bolt of the clamp 101. The clamp 101 no longer tightly sleeves the sleeve joint 1 under the faucet. After removing the sleeve joint 1, the function of clearing the blockage in the sewage pipe is completed. Since the present innovation flushes open the blockage by means of compressed air and high-pressure tap water, etc., the blockage deep in the sewage pipe will also be effectively removed, which brings convenience to the staff and correspondingly improves the work efficiency.
