Embodiment 1

[0028] Taking the water supply pipe network of a large city as an example, the water supply pressure range of the water supply pipe network is 30-60m, and the water flow velocity range in the pipe is 0.4-0.8m / s. The self-generating device described in the present invention is installed on a DN400 On the water distribution pipeline, supply power to the online residual chlorine meter installed on the pipeline, and the power supply pressure requirement of the residual chlorine meter is DC24V.

[0029] Such as figure 1 As shown, a self-generating device for an online monitoring instrument of a water supply pipe network is composed of a junction box 1, a sleeve 2, an impeller shaft 3, a ring 4 and a blade 5; the ring 4 is fixed on the bottom of the sleeve 2, and the The casing 2 is fixed on the impeller shaft 3 ; one end of the blade 5 is fixed on the bottom of the impeller shaft 3 , and the other end is fixed on the ring 4 . The power management module of the junction box include...

Embodiment 2

[0034] Such as Figure 4 and Figure 5 As shown, the self-generating device can also be applied to the bypass pipe, the specific method is:

[0035] a. Insert the self-generating device into the pipe section until the bottom of the impeller shaft 3 reaches the bottom of the pipe section; push the sleeve 2 to push the ring 4 into the pipe section, and the blade 5 fixed on the ring 4 is deformed into a spiral shape under force; put the sleeve 2. It is fixed on the outside of the pipe section by screw connection, welding or flange connection, and it is leak-proof treated to obtain a pipe section pre-installed with a self-generating device; the pipe section is packaged as a butt-joint short joint, and the joint The diameter is DN100~250, and the interface is threaded, flanged or clamped;

[0036] b. Drill holes before and after the valve on the main water supply pipe to install the bypass pipe. The diameter of the bypass pipe is DN100-250. The connection between the bypass pipe ...

Abstract

The invention belongs to the technical field of water transmission and distribution, and in particular relates to a self-generating device for an online monitoring instrument of a water supply pipe network and its application. The self-generating device is composed of a junction box, a sleeve, an impeller shaft, a ring and blades; the ring is fixed on the bottom of the sleeve, and the sleeve is sleeved on the impeller shaft; one end of the blade is fixed on the bottom of the impeller shaft , one end is fixed on the ring. The specific application method is: punch holes under pressure on the water supply pipe network in normal operation, the hole diameter is the same as the outer diameter of the ring; insert the self-generating device into the pipe until the bottom of the impeller shaft reaches the bottom of the pipe; push the sleeve to push the ring into Inside the pipeline, the blade fixed on the ring deforms into a spiral shape under force; the sleeve is fixed outside the pipeline. The self-generating device of the present invention can be directly installed on the water supply network in normal operation, which is convenient and fast, and the power output can ensure the real-time data transmission of the online monitoring instrument, which provides a favorable guarantee for the intelligent management of the water supply network.

Description

technical field [0001] The invention belongs to the technical field of water transmission and distribution, and in particular relates to a self-generating device for an online monitoring instrument of a water supply pipe network and its application. Background technique [0002] The online monitoring data reflects the operation status of the water supply network and is the basis for the intelligent management of the water supply network. The real-time transmission of the data directly affects the success or failure of the intelligent management of the water supply network. The biggest problem restricting the real-time transmission of the online monitoring data is Online monitoring instrument power supply problems. [0003] There are three main power supply methods for online monitoring instruments in China: AC power supply, solar power supply and battery power supply. For various online monitoring instruments with scattered layout, it is extremely difficult to use AC power ...
