Description

Technical Field

[0001] The utility model relates to the technical field of hydroelectric power generation equipment, in particular to a micro hydroelectric generator for a pipeline. Background Art

[0002] Taking into account the inconvenience of replacing batteries and the environmental and energy-saving effects of using converted alternating current, micro-generators are currently installed on power-consuming products such as induction faucets, temperature-sensing faucets, temperature-displaying faucets, touch-type faucets or pipelines for self-generation. However, the current micro-generators are all installed entirely on the waterway inside the faucet or pipe. For example, the prior art with patent number: CN105202257B, on the one hand, requires corresponding modifications to the faucet or pipe, which is large in size and inconvenient to assemble. At the same time, because the water flows directly over the generator components, it is easy to damage the generator's electronic components, and the materials are prone to aging and deterioration, resulting in a short generator life and affecting the water quality.

[0017] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0018] See also Figure 1-4 The utility model provides an embodiment: a micro hydroelectric generator for a pipeline, comprising a housing 1, a mounting cavity 4 is provided on the housing 1, and a generator 5 is provided in the mounting cavity 4; the motor shaft of the generator 5 passes through the mounting cavity 4 and is connected to the impeller 7 provided, and the impeller 7 is located in the first connecting member 2 provided at one end of the housing 1; water flow is introduced into the first connecting member 2 through a water channel 8 provided outside the mounting cavity 4 to promote the impeller 7 to rotate in the first connecting member 2 to provide power for the rotation of the generator 5; through the above scheme, since the generator 5 is located in the mounting cavity 4 and the water flow flows to the impeller 7 through the water channel 8, the generator 5 will not contact with the water flow, firstly, the service life of the generator 5 is guaranteed; secondly, the installation and maintenance of the generator 5 is facilitated; and thirdly, the influence of the generator 5 on the water quality is avoided. Among them, the water channel 8 is arranged between the housing 1 and the mounting cavity 4, so that the water flow passes through the first connecting member 2 of the outer flow channel of the mounting cavity 4 to impact the impeller 7.

[0019] Furthermore, since the housing 1 is provided with a second connection member 3 at one end away from the first connection member 2, the first connection member 2 and the second connection member 3 are connected to the water pipeline to install the device on the water pipeline. In summary, the device is connected to the water pipeline using two connection parts, so that the device can be directly installed on the water pipeline, so that the device can be independently installed outside the faucet, thereby solving the problem that the existing generator needs to be installed in the faucet housing, which causes inconvenience in installation and maintenance.

[0020] In order to facilitate the assembly of the device, especially to facilitate the replacement of the two connecting parts; the housing 1 is also provided with a fastener 9, and the fastener 9 passes through the housing 1 and is connected to the first connecting part 2, so as to fix the first connecting part 2 at one end of the housing 1. The fastener 9 is preferably a bolt, and a sealing ring is used to seal the fastener 9 and the housing 1. Based on this, tightening the fastener 9 can ensure the reliable connection between the two connecting parts and the housing 1; loosening the fastener 9 can remove the two connecting parts from the housing 1. This facilitates the installation and replacement of the connecting parts.

[0021] In addition, the connection form between the first connector 2 and the second connector 3 and the water pipeline is selected according to the material of the water pipeline; for example, when the water pipeline is a hose, the first connector 2 and the second connector 3 are connected to the water pipeline through the provided insert 23. When the water pipeline is a stainless steel pipe, the insert 23 can be set as an external thread column, and the nut on the water pipeline is connected to the external thread column to fix the device on the water pipeline.

[0022] On the basis of the above scheme, since an impeller chamber 20 for accommodating the impeller 7 is also provided in the first connecting member 2, and the impeller chamber 20 is connected to the water channel 8 through the guide port 21, the impeller chamber 20 can be used to provide a reliable working range for the impeller 7, and the guide port 21 can also be used to collect water flow to impact the impeller 7, thereby ensuring that the impeller 7 can rotate normally.

[0023] Furthermore, since a guide plate 22 is also provided on the outside of the guide port 21, wherein the guide plate 22 cooperates with the guide port 21 to guide the water flow to impact the impeller 7, the guide port 21 and the guide plate 22 can cooperate to guide the water flow to impact the impeller 7. Specifically, the guide port 21 and the guide plate 22 guide the water surface of the water flow to impact between two adjacent blades to provide efficient and reliable power for the rotation of the impeller 7.

[0024] Furthermore, since a temperature probe 6 is also provided in the installation cavity 4, and the temperature probe 6 contacts the water flow in the water channel 8 after passing through the shell 1; specifically, the generator 5 is used to power the temperature probe 6, so the temperature probe 6 can be used to obtain the water temperature inside the shell 1 in real time.

[0025] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
