Description

Technical Field

[0001] This utility model relates to the field of exhaust in drainage robots, specifically a drainage robot that prevents water from entering through its exhaust pipe. Background Technology

[0002] The drainage robot is equipped with a drainage pump inside a vehicle with electrically driven wheels. When the drainage pump is running, it can drain the water accumulated in low-lying areas. In order to avoid air blockage and air trapping, an exhaust nozzle is added to the drainage pump. The water and air are automatically separated by the difference in density. The air moves upward and enters the exhaust nozzle, and is discharged outward through the one-way exhaust valve on the exhaust nozzle.

[0003] The design of the aforementioned vent valve can cause blockage of the vent nozzle during drainage processes, as some water or silt splashes upwards and falls above it, preventing gas from being discharged smoothly. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-3In this embodiment of the utility model, a drainage robot that prevents water from entering through the exhaust pipe includes a vehicle body 1. A drainage pump is installed inside the vehicle body 1. An inlet pipe 2 extending to the outside of the vehicle body 1 is fixedly installed at the input end of the drainage pump. A drainage pipe 3 extending to the outside of the vehicle body 1 is fixedly installed at the output end of the drainage pump. A connecting pipe 4 is connected to the exhaust port of the drainage pump through a pipe. The connecting pipe 4 is fixedly installed at the top of the vehicle body 1 and extends upward. The end of the connecting pipe 4 that is not connected to the vehicle body 1 has a 90-degree bend structure. An anti-blocking mechanism is installed at the end of the connecting pipe 4 that is not connected to the vehicle body 1.

[0015] In this embodiment: after a rainstorm, when water accumulates in low-lying areas (such as underground garages), it is necessary to pump the water out of the low-lying areas through drainage methods. At this time, the device is started and moved towards the water accumulation location until the port of the water inlet pipe 2 is completely submerged in the water. Then, the drainage pump in the vehicle body 1 is started. The suction generated by the operation of the drainage pump draws in the water and discharges it through the drainage pipe 3. The water is then transported into the underground manhole through the delivery pipe connected to the drainage pipe 3. During the movement of the device, if the water inlet pipe 2 gradually rises above the water level due to the drop in water level, the vehicle body 1 is started again and moved into the water until the water inlet pipe 2 is completely submerged in the water again. Therefore, the device gradually moves into the accumulated water during the drainage process, and is not completely inserted into the deep water all at once. Thus, the connecting pipe 4 is located above the water level. During the operation of the drainage pump, due to the difference in density between water and air, the air in the drainage pump and drainage channel will move upward and exert a squeezing force on the air pressure valve of the exhaust nozzle on the drainage pump, so that the air enters the connecting pipe 4 through the pipe. As the air increases, the air pressure increases, exerting a squeezing force on the anti-clogging mechanism, thus enabling the air to be discharged outward. Since one end of the connecting pipe 4 is bent, when the anti-clogging mechanism is opened, it can prevent external impurities or water from entering the connecting pipe 4 when the anti-clogging mechanism is open, thereby avoiding the problem of blockage.

[0016] Please refer to this carefully. Figure 2 and Figure 3 The anti-blocking mechanism includes a connecting boss 5 integrally formed on the upper part of the bend of the connecting pipe 4. A sliding rod 11 is slidably installed on the inner wall of the connecting boss 5, extending through to the bottom end of the bend of the connecting pipe 4. The top of the sliding rod 11 extends above the connecting boss 5. A sealing plate 13 is fixedly installed at the bottom end of the sliding rod 11. A spring 12 is fixedly installed at the bottom end of the baffle mechanism and the top end of the connecting boss 5. The anti-blocking mechanism also includes a retaining ring 10 integrally formed on the inner wall of the bend of the connecting pipe 4. A sealing ring 14 is installed at the top end of the sealing plate 13. A mating groove 15 that matches the outer wall of the sealing ring 14 is opened at the bottom end of the retaining ring 10.

[0017] In this embodiment: as the air pressure in the connecting pipe 4 gradually increases, the air pressure acts on the top of the sealing plate 13. When the air pressure is greater than the return force of the spring 12, the spring 12 is compressed under the gas pressure. At this time, the sealing plate 13 drives the baffle mechanism to move downward through the sliding rod 11, and the spring 12 is compressed. At this time, the sealing plate 13 drives the sealing ring 14 to move downward synchronously and separate from the docking groove 15. At this time, the gas can move outward from the gap between the sealing plate 13 and the sealing ring 14. Since the top of the connecting pipe 4 is bent downward, when the anti-blocking mechanism is opened to vent, external water or impurities cannot enter the connecting pipe 4, thus avoiding the venting blockage problem caused by impurities or water entering.

[0018] Please refer to this carefully. Figure 2 and Figure 3 The baffle mechanism includes a stud 8 integrally formed on the top of the sliding rod 11 and extending upward. A disc 7 is inserted into the outer wall of the stud 8. The diameter of the stud 8 is smaller than the diameter of the sliding rod 11. A circular hole with the same outer diameter as the stud 8 is opened inside the disc 7. A locking nut 9 is threadedly connected to the outer wall of the stud 8. The locking nut 9 in the tightened state is used to press the top of the disc 7.

[0019] In this embodiment: when the spring 12 experiences metal fatigue and insufficient elasticity during prolonged use, the locking nut 9 can be loosened and disassembled by using a wrench. This allows the disc 7 to be pulled upwards and separated from the stud 8, enabling the spring 12 to be disassembled and replaced, thus maintaining the protective capability of the protective mechanism.

[0020] Please refer to this carefully. Figure 2 and Figure 3 A protective telescopic tube 6 is fixedly connected between the top of the connecting boss 5 and the bottom of the disc 7, and the protective telescopic tube 6 is sleeved on the outer periphery of the spring 12.

[0021] In this embodiment: the protective telescopic tube 6 is made of corrugated pipe to protect the spring 12 and prevent corrosion caused by long-term contact with water. The protective telescopic tube 6 is fixedly connected to both ends with adhesive. Therefore, after the protective telescopic tube 6 is disassembled, it can be fixed by reapplying adhesive.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
