Description

Technical Field

[0001] This utility model relates to the field of water pump technology, specifically to a water pump exhaust mechanism. Background Technology

[0002] The reliability of the water pump exhaust mechanism directly affects the equipment's lifespan and operational continuity. Especially in scenarios involving the transport of media containing trace impurities or easily crystallizing substances, the exhaust pipe is prone to mechanical blockage due to impurity accumulation or structural interference. Furthermore, since traditional exhaust mechanisms accelerate airflow by rotating a fixedly installed air guide fan, the fixed gap between the air guide fan and the inner wall of the pipe is easily filled with deposits over long-term operation, which can directly lead to mechanical failure, causing exhaust interruption or even equipment damage.

[0003] In existing technologies, the inner diameter of the pipe is usually increased or a filter device is added to alleviate blockage. However, this not only increases manufacturing costs but also reduces exhaust efficiency. In other words, the fixed installation mode of the air guide fan makes it unable to actively avoid the area where impurities are deposited, and the rigid connection between the rotating rod and the pipe lacks displacement compensation capability when heated or vibrated. Therefore, when impurities accumulate locally in the gap between the air guide fan and the pipe, the continuous rotation of the fixed air guide fan will accelerate wear and may even cause overload damage to the transmission mechanism due to a sudden increase in resistance.

[0004] In view of this, a water pump exhaust mechanism is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the fixed installation of the air guide fan in the traditional water pump exhaust mechanism is prone to mechanical blockage due to gap deposition, which leads to overload damage, and to provide a water pump exhaust mechanism.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a water pump exhaust mechanism, including a water pump body, an exhaust port on the water pump body, an exhaust pipe connected to the exhaust port, an air pump at the end of the exhaust pipe away from the water pump body, and a flow guiding component for improving the exhaust effect on the exhaust pipe.

[0007] The flow guiding assembly includes a mounting plate fixedly connected to the pipe, an electric push rod fixedly connected to the mounting plate, and a movable plate fixedly connected to the extended end of the electric push rod. Three rotating rods are rotatably connected to the movable plate. All three rotating rods penetrate the wall of the exhaust pipe, and a guide fan is fixedly connected to one end of each of the three rotating rods inside the exhaust pipe. A motor is fixedly connected to the movable plate. The motor drives the rotating rods to rotate the guide fan. The guide fan is used to improve the gas passage efficiency in the exhaust pipe when rotating, thereby improving the exhaust effect of the water pump.

[0008] Preferably, each of the three rotating rods is fixedly connected to a pulley and is linked by a transmission belt, so that when any rotating rod rotates, it can drive the other two rotating rods to rotate synchronously. Each of the three rotating rods is fixedly connected to a rotating ring with a T-shaped cross section, and the exhaust pipe is provided with a rotating groove for the rotating ring to rotate.

[0009] Preferably, a drive gear is fixedly connected to the output end of the motor, and a driven gear is rotatably connected to the pipe. The driven gear slides on any one of the three rotating rods, and the driven gear meshes with the drive gear and is rotatably connected to the pipe.

[0010] Preferably, a connecting rod is fixedly connected to the driven gear, the connecting rod is hollow and its cross-section is L-shaped, and a connecting groove adapted to the size of the connecting rod is opened on the exhaust pipe.

[0011] Preferably, a slide rod is fixedly connected to the driven gear, and one of the three rotating rods that is slidably disposed with the driven gear has a movable groove for sliding of the slide rod. The slide rod and the movable groove are used to enable the rotating rod to slide relative to the driven gear.

[0012] Preferably, the blades of the air guide fan are arc-shaped and tilted at an angle of 45°-60°. Both the blades of the air guide fan and the transmission belt are made of elastic silicone material, which is used to reduce gas turbulence and transmission vibration, thereby further improving exhaust efficiency.

[0013] Preferably, the electric push rod can drive the air guide fan to move a distance that is just enough to prevent the air guide fan from contacting the inner wall of the exhaust pipe, and the distance that the electric push rod drives the air guide fan to move is the same as the length of the movable groove.

[0014] Compared with the prior art, this utility model has the following beneficial effects:

[0015] The water pump exhaust mechanism provided by this utility model can drive the air guide fan to move horizontally in the exhaust pipe through the linkage between the electric push rod and the movable plate, so that the air guide fan actively avoids the area where impurities are deposited. At the same time, by adjusting the distance between the air guide fan and the inner wall of the pipe, it can effectively prevent mechanical blockage caused by the accumulation of deposits in the gap, and greatly improve the exhaust continuity and equipment life.

[0016] The water pump exhaust mechanism provided by this utility model uses a design that links the pulleys of three rotating rods with the transmission belt. Combined with the 45°-60° arc tilt angle of the air guide fan blades and the elastic silicone material, it significantly reduces gas turbulence loss and transmission vibration, thereby enhancing exhaust efficiency while reducing wear and achieving stable operation with low noise and high energy efficiency.

[0017] The water pump exhaust mechanism provided by this utility model has the ability to compensate for axial displacement when the rotating rod drives the air guide fan to rotate through the sliding cooperation of the driven gear, slide rod and movable groove. This avoids the problem of rigid connection overload caused by thermal expansion and contraction or impurity resistance, and further ensures the reliability and impact resistance of the transmission mechanism.

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Please see Figure 1-6 .

[0029] This utility model's water pump exhaust mechanism includes a water pump body 1, an exhaust port 11 on the water pump body 1, an exhaust pipe 12 connected to the exhaust port 11, an air pump 13 at the end of the exhaust pipe 12 away from the water pump body 1, and a flow guide component 2 for improving the exhaust effect on the exhaust pipe 12. That is, through the cooperation of the flow guide component 2 and the air pump 13, the airflow path can be actively adjusted during the exhaust process, avoiding the monotony of the traditional fixed flow guide structure, adapting to different gas distribution conditions, and improving the exhaust response speed. In specific implementation, devices such as air pressure sensors can be added to optimize airflow monitoring.

[0030] The flow guiding assembly 2 includes a mounting plate 21 fixedly connected to the pipe, an electric push rod 23 fixedly connected to the mounting plate 21, and a movable plate 22 fixedly connected to the extended end of the electric push rod 23. Three rotating rods 24 are rotatably connected to the movable plate 22. All three rotating rods 24 are set through the wall of the exhaust pipe 12, and one end of each of the three rotating rods 24 located inside the exhaust pipe 12 is fixedly connected to a guide fan 25. A motor 26 is fixedly connected to the movable plate 22. The motor 26 is used to drive the rotating rods 24 to drive the guide fan 25 to rotate. The guide fan 25 is used to improve the gas passage efficiency in the exhaust pipe 12 when rotating, thereby improving the exhaust effect of the water pump. This arrangement allows the movable plate 22 to move horizontally through the electric push rod 23, driving the three guide fans 25 to adjust their positions synchronously. This can actively avoid areas where impurities are deposited and optimize the airflow coverage. At the same time, the motor 26 drives the guide fan 25 to rotate and accelerate the exhaust, achieving the dual functions of dynamic flow guiding and efficient exhaust.

[0031] Secondly, pulleys 212 are fixedly connected to each of the three rotating rods 24 and are linked by a transmission belt 213, so that when any rotating rod 24 rotates, it can drive the other two rotating rods 24 to rotate synchronously. A rotating ring 214 with a T-shaped cross section is fixedly connected to each of the three rotating rods 24. A rotating groove 216 for rotating the rotating ring 214 is opened on the exhaust pipe 12. In other words, through the linkage design of the pulleys 212 and the transmission belt 213, the three air guide fans 25 can be ensured to rotate synchronously, avoiding the problem of uneven torque when a single motor 26 drives multiple rotating rods 24. At the same time, the T-shaped rotating ring 214 and the rotating groove 216 cooperate to allow the rotating rod 24 to move axially with the movable plate 22, while limiting radial offset, ensuring the stability of the air guide fan 25 when it moves.

[0032] Furthermore, a drive gear 27 is fixedly connected to the output end of the motor 26, and a driven gear 28 is rotatably connected to the pipe. The driven gear 28 slides on any one of the three rotating rods 24. The driven gear 28 is meshed with the drive gear 27 and rotatably connected to the pipe. Through gear meshing transmission, the power of the motor 26 can be stably transmitted to the rotating rod 24. The sliding fit design between the driven gear 28 and the rotating rod 24 allows the rotating rod 24 to maintain the continuity of power transmission when it moves horizontally, solving the displacement limitation problem caused by traditional rigid connection.

[0033] In addition, a connecting rod 211 is fixedly connected to the driven gear 28. The connecting rod 211 is hollow and has an L-shaped cross section. A connecting groove 215 that matches the size of the connecting rod 211 is provided on the exhaust pipe 12. The cooperation between the L-shaped connecting rod 211 and the connecting groove 215 can ensure the stability of the driven gear 28 on the pipe and ensure that the driven gear 28 is always meshed with the drive gear 27.

[0034] Among them, a slide rod 29 is fixedly connected to the driven gear 28. Among the three rotating rods 24, the rotating rod 24 that is slidably disposed with the driven gear 28 has a movable groove 210 for sliding the slide rod 29. The slide rod 29 and the movable groove 210 are used to enable the rotating rod 24 to slide relative to the driven gear 28. Since the sliding cooperation between the slide rod 29 and the movable groove 210 provides axial displacement compensation space for the rotating rod 24, when the pipeline is heated and expands or the air guide fan 25 is resisted, the rotating rod 24 can adaptively adjust its position to avoid jamming or overload damage to the transmission mechanism caused by rigid connection.

[0035] Furthermore, the blades of the air guide fan 25 are arc-shaped with an inclination angle of 45°-60°. Both the blades of the air guide fan 25 and the transmission belt 213 are made of elastic silicone material, which is used to reduce gas turbulence and reduce transmission vibration, thereby further improving exhaust efficiency. Since the inclination angle of the arc-shaped blades optimizes the tangential flow of gas, it can reduce eddy current energy loss. The elastic silicone material has both flexibility and wear resistance, which can not only buffer transmission vibration, but also withstand long-term friction from impurity particles, thus extending service life.

[0036] Specifically, the electric push rod 23 can drive the air guide fan 25 to move a distance that ensures the air guide fan 25 does not contact the inner wall of the exhaust pipe 12. In other words, the stroke design of the electric push rod 23 must ensure that the air guide fan 25 always maintains a safe gap with the inner wall of the pipe when moving horizontally, and the distance that the electric push rod 23 drives the air guide fan 25 to move is the same as the length of the movable groove 210. This setting can ensure that the air guide fan 25 always maintains a safe gap with the inner wall of the pipe when moving horizontally by limiting the matching relationship between the moving distance of the air guide fan 25 and the length of the movable groove 210, which avoids friction damage and makes full use of the displacement margin of the movable groove 210 to adapt to different working conditions.

[0037] When the exhaust mechanism of this water pump is working, the motor 26 transmits power to the rotating rod 24 through the meshing of the drive gear 27 and the driven gear 28, driving the air guide fan 25 to rotate at high speed to accelerate the gas discharge. At the same time, the electric push rod 23 pushes the movable plate 22 to move horizontally along the axial direction of the exhaust pipe 12, so that the air guide fan 25 can adjust its position in real time according to the gas distribution or impurity accumulation, avoiding the accumulation of fixed gaps. The three rotating rods 24 are linked by the transmission belt 213 to ensure that the air guide fan 25 rotates synchronously. The sliding fit design of the slide rod 29 and the movable groove 210 provides axial displacement compensation for the rotating rod 24, eliminating stress concentration caused by thermal expansion and contraction or vibration.

[0038] It is important to note that during use, the wear condition of the elastic silicone material of the air guide fan 25 blades should be checked regularly to ensure its anti-turbulence and vibration reduction performance. It is also necessary to monitor the matching relationship between the stroke of the electric push rod 23 and the movable groove 210 to prevent the air guide fan 25 from displacing beyond the limit and contacting the inner wall of the pipe. At the same time, the gear meshing parts and the transmission belt 213 should be lubricated and maintained regularly to avoid transmission jamming caused by impurities. In addition, when conveying media that are prone to crystallization or have high impurities, the position adjustment cycle of the air guide fan 25 should be shortened to actively avoid areas with deposition risk, so as to maintain exhaust efficiency and long-term stable operation of the equipment.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
