Intelligent water saving and energy saving control device

Abstract

This application relates to the technical field of smart water management, and in particular to a smart water management energy-saving and water-saving control device, including a downpipe and a blade adjustment device. This solution uses an arc-shaped guide plate, with its concave surface facing the direction of water flow and its convex surface facing the impeller. This causes the water to flow along the arc-shaped surface during its descent, changing the water's trajectory and converging the dispersed water flow to guide it to the blades of the impeller. This enhances the impact force of the water flow on the impeller, improving energy conversion efficiency. The excess potential energy of the water flow is converted into electrical energy for utilization. Simultaneously, the rotating shaft drives gear two to rotate, gear two drives gear one to rotate, and gear one adjusts the angle of attack between the rotating shaft one and the impeller blades. At high flow rates, the angle of attack is reduced to avoid impeller overload, while at low flow rates, the angle of attack is increased to fully capture water flow energy, maintaining high energy conversion efficiency at both high and low flow rates.

Description

Technical Field

[0001] This application relates to the technical field of smart water management, and in particular to a smart water management energy-saving and water-saving control device. Background Technology

[0002] The municipal water supply network is an important part of urban infrastructure. It consists of underground and above-ground water supply pipelines that guarantee various aspects of residents' lives, enterprise production, public services, and fire protection. When supplying water to areas at higher elevations, the water is first stored in a high-altitude water tank, and then the water in the water tank is supplied downwards through water pipes.

[0003] A utility model patent with Chinese patent authorization announcement number CN222025172U discloses a smart water management energy-saving and water-saving control device, including a downpipe. A branch pipe is fixedly connected to one side of the downpipe, and a solenoid valve is installed on the branch pipe. A drive shaft is rotatably connected to the inner wall of the downpipe via a bearing. A force-bearing impeller is fixedly sleeved on the inner wall of the drive shaft within the downpipe. A generator is also fixedly installed on the outer wall of the downpipe. One end of the drive shaft extends out of the downpipe and is fixedly connected to the input end of the generator. An impact intensity monitoring and feedback mechanism is also fixedly installed on the drive shaft and the outer wall of the downpipe. This application can convert excess potential energy of water flow into electrical energy for utilization, thus saving energy and protecting the environment.

[0004] The proposed solution has the following problems: While it uses a drive shaft to rotate the input end of a generator, thus generating electricity and storing energy, converting excess potential energy of the water flow into electrical energy, this solution suffers from several issues. For example, the water flow in the downpipe directly impacts the impeller without a dedicated flow guidance structure. This results in the water flow being dispersed when impacting the impeller blades, failing to concentrate its force on the blades and causing some potential energy to be unutilized, leading to energy loss. Furthermore, the impeller blades and drive shaft are fixedly connected, with a fixed angle of attack that cannot be adjusted according to changes in water velocity. At high flow rates, the fixed angle of attack may cause excessive impact on the impeller, increasing energy loss and potentially affecting the device's lifespan. Conversely, at low flow rates, the fixed angle of attack makes it difficult to fully capture the water's potential energy, further reducing energy conversion efficiency.

[0005] Therefore, in order to solve the above problems, this application provides a smart water management energy-saving and water-saving control device. Utility Model Content

[0006] To address the problem that the blades of the load-bearing impeller are fixedly connected to the drive shaft, resulting in a fixed blade angle of attack that cannot be adjusted according to changes in water flow velocity, this application provides a smart water management energy-saving and water-saving control device.

[0007] This application provides a smart water management energy-saving and water-saving control device, including a downpipe and a blade adjustment device. A drive shaft is rotatably connected to the bottom end of the downpipe. Force-receiving impellers are arranged on all four sides of the drive shaft. A blade adjustment device is provided between the drive shaft and each of the four force-receiving impellers. The blade adjustment device includes:

[0008] A second mounting groove is provided through one side of the drive shaft, and a first mounting groove is provided through one side of the force-bearing impeller near the drive shaft. A second rotating shaft is located in the second mounting groove, and a second gear is fixedly connected to the middle of the second rotating shaft. A first rotating shaft is fixedly connected in the first mounting groove, and a first gear is fixedly connected to the middle of the first rotating shaft. The first gear meshes with the second gear.

[0009] A drive assembly is provided on one side of each of the two adjacent blade adjustment devices.

[0010] Preferably, both ends of the first rotating shaft are fixedly connected to a first fixing ring, both ends of the second rotating shaft are fixedly connected to a second fixing ring, and a connecting rod is fixedly connected between the two first fixing rings and the second fixing ring.

[0011] Preferably, the inner wall of the downpipe is provided with an arc-shaped guide plate, which is located at the top of the force-bearing impeller.

[0012] Preferably, the concave surface of the arc-shaped guide plate faces the direction of the water flow, and the convex surface of the arc-shaped guide plate faces the impeller under force.

[0013] Preferably, a water distribution pipe is connected to one side of the top of the downpipe, and a solenoid valve is installed on the water distribution pipe.

[0014] Preferably, the driving component includes:

[0015] One end of each of the two rotating shafts is fixedly connected to a bevel gear, and a bevel gear is provided on one side of each of the two bevel gears. The bevel gears mesh with each other, and an installation groove is provided between the two bevel gears. A dual-axis motor is provided in the installation groove, and the output end of the dual-axis motor is fixedly connected to the bevel gear through a connecting shaft.

[0016] Preferably, the top and bottom of the dual-axis motor are both provided with L-shaped slots, and the first bevel gear and the second bevel gear are located in the L-shaped slots.

[0017] Preferably, the two drive components are arranged in a cross shape.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] 1. In this utility model, by setting an arc-shaped guide plate with its concave surface facing the direction of water flow and its convex surface facing the impeller, the water flow is made to flow along the arc-shaped surface during its descent, changing the trajectory of the water flow. This gathers the dispersed water flow and guides it to the blades of the impeller, thereby enhancing the impact force of the water flow on the impeller and improving the energy conversion efficiency. After acting on the impeller, the excess potential energy of the water flow is converted into electrical energy for utilization. At the same time, the second shaft drives the second gear to rotate, the second gear drives the first gear to rotate, and the first gear drives the first shaft to adjust the angle of attack of the blades of the impeller. At high flow rates, the angle of attack is reduced to avoid impeller overload, and at low flow rates, the angle of attack is increased to fully capture the energy of the water flow. It can maintain a high energy conversion efficiency at both high and low flow rates, further increasing power generation and enhancing the energy-saving characteristics of the device.

[0020] 2. In this utility model, a dual-shaft motor drives the connecting shafts at the top and bottom to rotate. The two connecting shafts drive two bevel gears to rotate, which in turn drive bevel gear one to rotate. The two bevel gears one then drive the rotating shaft two to rotate, thereby driving gear two to rotate. This provides stable and balanced power for adjusting the blade angle of attack, making the blade angle adjustment more precise and responsive under different water flow velocities. The blade angle of attack can be optimized in real time according to the actual impact intensity of the water flow in the downpipe. When the water flow velocity is high, the angle of attack can be quickly reduced to reduce the impeller load and avoid component wear caused by excessive impact. When the water flow velocity is low, the angle of attack can be increased in time to fully capture the water flow potential energy and improve the generator's efficiency in converting water flow energy.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1, as Figure 1-5 As shown, this utility model provides a smart water management energy-saving and water-saving control device, including a downpipe 1, a blade adjustment device, and a drive assembly. A drive shaft 5 is rotatably connected to the bottom end of the downpipe 1. Force-receiving impellers 6 are provided on all four sides of the drive shaft 5. Four blade adjustment devices are provided, each including: a second mounting groove 20 extending through one side of the drive shaft 5; a first mounting groove 7 extending through the side of the force-receiving impellers 6 near the drive shaft 5; a second rotating shaft 16 rotating within the second mounting groove 20; a second gear 14 fixedly connected to the middle of the second rotating shaft 16; a first rotating shaft 10 fixedly connected within the first mounting groove 7; a first gear 9 fixedly connected to the middle of the first rotating shaft 10; and the first gear 9 meshing with the second gear 14. Both ends of the 0 are fixedly connected to a fixing ring 8, and both ends of the rotating shaft 16 are fixedly connected to a fixing ring 15. A connecting rod 11 is fixedly connected between the two fixing rings 8 and the fixing ring 15. An arc-shaped guide plate 4 is provided on the inner wall of the downpipe 1. The arc-shaped guide plate 4 is located on the top of the force-bearing impeller 6. The concave surface of the arc-shaped guide plate 4 faces the direction of water flow, and the convex surface of the arc-shaped guide plate 4 faces the force-bearing impeller 6. This allows the water to flow along the arc-shaped surface during the fall, changing the trajectory of the water flow. The dispersed water flow is then gathered and guided to the blades of the force-bearing impeller 6, thereby enhancing the impact force of the water flow on the impeller and improving the energy conversion efficiency. A water distribution pipe 2 is connected to one side of the top of the downpipe 1. A solenoid valve 3 is installed on the water distribution pipe 2.

[0030] In this embodiment, water flows down from the drain pipe 1 and passes through the arc-shaped guide plate 4. The concave surface of the arc-shaped guide plate 4 faces the direction of the water flow, and the convex surface faces the impeller 6. This causes the water to flow along the arc-shaped surface during its descent, changing the trajectory of the water flow. The dispersed water flow is then gathered and guided to the blades of the impeller 6, thereby increasing the impact force of the water flow on the impeller and improving the energy conversion efficiency. After acting on the impeller 6, the excess potential energy of the water flow is converted into electrical energy for utilization. At the same time, the rotating shaft 16 drives the gear 14 to rotate, the gear 14 drives the gear 9 to rotate, and the gear 9 drives the rotating shaft 10 to adjust the angle of attack of the blades of the impeller 6. Meanwhile, the fixing ring 8, the fixing ring 15, and the connecting rod 11 fix the impeller 6 and the transmission shaft 5 together. This maintains a high energy conversion efficiency under both high and low flow rates, further increasing the power generation.

[0031] Example 2, as Figure 1-5 As shown, the drive assembly includes: two rotating shafts 16, one end of which is fixedly connected to a bevel gear 12; a bevel gear 13 is provided on one side of the two bevel gears 12; the bevel gears 12 and 13 mesh with each other; a mounting groove is provided between the two bevel gears 13; a dual-axis motor 17 is provided in the mounting groove; the output end of the dual-axis motor 17 is fixedly connected to the bevel gear 13 via a connecting shaft 18; an L-shaped groove 19 is provided at both the top and bottom of the dual-axis motor 17; the bevel gears 12 and 13 are located in the L-shaped groove 19; and the two drive assemblies are arranged in a cross shape.

[0032] In this embodiment, the dual-axis motor 17 is started, which drives the connecting shafts 18 at the top and bottom to rotate. The two connecting shafts 18 drive the two bevel gears 13 to rotate, the bevel gears 13 drive the bevel gears 12 to rotate, and the two bevel gears 12 drive the rotating shaft 16 to rotate, thereby driving the gear 14 to rotate, which can drive the impeller 6 to adjust the blade angle of attack.

[0033] Working principle: During use, water flows down from the drain pipe 1, passes through the arc-shaped guide plate 4, with the concave surface of the guide plate 4 facing the direction of water flow and the convex surface facing the impeller 6. This causes the water to flow along the arc-shaped surface during its descent, changing the trajectory of the water flow and converging the dispersed water flow before guiding it to the blades of the impeller 6. This enhances the impact force of the water flow on the impeller and improves the energy conversion efficiency. After acting on the impeller 6, the excess potential energy of the water flow is converted into electrical energy for utilization. Simultaneously, the dual-shaft motor 17 is started, driving the connecting shaft 1 between the top and bottom. The rotation of shaft 8 drives two bevel gears 13 to rotate, which in turn drives bevel gear 12 to rotate. The two bevel gears 12 drive shaft 16 to rotate, which in turn drives gear 14 to rotate. Gear 14 drives gear 9 to rotate, which in turn drives shaft 10 to adjust the angle of attack of the blades of the impeller 6. At the same time, the fixing ring 8, fixing ring 15, and connecting rod 11 fix the impeller 6 to the drive shaft 5, maintaining high energy conversion efficiency under both high and low flow rates, further increasing power generation.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
