[0032] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0033] Example 1

[0034] See also Figure 1 , this embodiment 1 provides a flow meter and solenoid valve control device with energy recovery.

[0035] First of all, it should be noted that this device is intended to control the flow rate of the target pipeline into which the fluid is passed. Since the target pipeline is placed underground, it is not possible to use solar energy, wind energy, etc. in the prior art to recover energy and power supply, so this device uses the kinetic energy of the fluid in the pipeline to recover energy and power supply. Of course, the use scenario of this device is not limited to underground: as long as there is fluid flowing through the pipeline, this device can be used to achieve power supply.

[0036] In this embodiment 1, the target pipeline is provided with a solenoid valve, and the solenoid valve is equipped with a solenoid valve controller. The target pipeline is provided with a flow detector. Specifically, the flow detector is a commercially available flow meter and is provided on the target pipeline.

[0037] In general, see Figure 1 , Figure 2 The device includes: a mounting tube, a control box 2, and a kinetic energy recovery component.

[0038] The installation pipe 1 is used to connect with the target pipeline. Generally, the two can be connected by flanges: for convenient connection, a flange seat 101 can be set at one end of the installation pipe 1, and a flange seat 2 102 can be set at the other end. The flange seat 101 and the flange seat 2 102 are determined according to the specifications of the target pipeline: they can be the same specifications or different specifications. In this way, the fluid entering the target pipeline will also flow through the installation pipe 1.

[0039] The control box 2 is arranged on the outer wall of the mounting tube 1; a DC generator is arranged in the control box 2. The DC generator can adopt a commercially available generator motor and realize power generation by using the principle of electromagnetic induction.

[0040] The kinetic energy recovery component is arranged in the mounting tube 1; the kinetic energy recovery component includes an impeller 401 and a drive shaft 402; the impeller 401 is connected to one end of the drive shaft 402, and the other end of the drive shaft 402 extends into the control box 2 and is connected to the drive end of the DC generator.

[0041] See also Figure 3 , a rectifier and a battery are also provided in the control box 2; the output end of the DC generator is electrically connected to the battery through the rectifier - that is, the DC generator is used to charge the battery.

[0042] Then, the impeller 401 drives the driving shaft 402 to rotate under the drive of the fluid, and the driving shaft 402 drives the DC generator to work. The DC generator generates electricity and generates a relatively stable charging current through the rectifier, thereby charging the battery.

[0043] Considering the uncertain flow rate of pipeline fluid, this device is recommended to be installed in a horizontal direction: Figure 2 As shown, when the mounting tube 1 is horizontally arranged, the control box 2 is located at the outer top of the mounting tube 1, and the impeller 401 is close to the inner bottom of the mounting tube 1, thereby ensuring that even when the flow rate is small, the fluid can contact the impeller 401 to achieve energy recovery.

[0044] The battery is used to power the solenoid valve controller and flow meter.

[0045] Specifically, the solenoid valve is located outside the control box 2, but the solenoid valve controller can be set inside the control box 2 and electrically connected to the battery. In order for the solenoid valve controller to control the solenoid valve, it is necessary to connect the solenoid valve controller to the solenoid valve through a control wire. In this way, the control box 2 needs to be processed with a wire opening 201 for the control wire to pass through.

[0046] Similarly, since the battery is placed in the control box 2 and the flow meter is located outside the control box 2, in order to electrically connect the flow meter to the battery, the flow meter needs to be connected to the flow meter through a power supply wire. In this way, the control box 2 needs to be processed with a wire opening 2 for the power supply wire to pass through.

[0047] Since both are used for wiring, the first wiring opening 201 and the second wiring opening can be located at the same position and be the same hole.

[0048] Example 2

[0049] This embodiment 2 provides another flow meter and solenoid valve control device with energy recovery.

[0050] First of all, it should be noted that this device is intended to control the flow rate of the target pipeline into which the fluid is passed. Since the target pipeline is placed underground, it is not possible to use solar energy, wind energy, etc. in the prior art to recover energy and power supply, so this device uses the kinetic energy of the fluid in the pipeline to recover energy and power supply. Of course, the use scenario of this device is not limited to underground: as long as there is fluid flowing through the pipeline, this device can be used to achieve power supply.

[0051] In this embodiment 2, the target pipeline is provided with a solenoid valve, and the solenoid valve is equipped with a solenoid valve controller. The target pipeline does not need to be equipped with a flow detector, but the flow detector is integrated into the device.

[0052] In general, see Figure 1 , Figure 2 The device includes: a mounting tube 1, a control box 2, and a kinetic energy recovery component.

[0053] The installation pipe 1 is used to connect with the target pipeline. Generally, the two can be connected by flanges: for convenient connection, a flange seat 101 can be set at one end of the installation pipe 1, and a flange seat 2 102 can be set at the other end. The flange seat 101 and the flange seat 2 102 are determined according to the specifications of the target pipeline: they can be the same specifications or different specifications. In this way, the fluid entering the target pipeline will also flow through the installation pipe 1.

[0054] The control box 2 is arranged on the outer wall of the mounting tube 1; a DC generator is arranged in the control box 2. The DC generator can adopt a commercially available generator motor and realize power generation by using the principle of electromagnetic induction.

[0055] The kinetic energy recovery component is arranged in the mounting tube 1; the kinetic energy recovery component includes an impeller 401 and a drive shaft 402; the impeller 401 is connected to one end of the drive shaft 402, and the other end of the drive shaft 402 extends into the control box 2 and is connected to the drive end of the DC generator.

[0056] See also Figure 3 , a rectifier and a battery are also provided in the control box 2; the output end of the DC generator is electrically connected to the battery through the rectifier - that is, the DC generator is used to charge the battery.

[0057] Then, the impeller 401 drives the driving shaft 402 to rotate under the drive of the fluid, and the driving shaft 402 drives the DC generator to work. The DC generator generates electricity and generates a relatively stable charging current through the rectifier, thereby charging the battery.

[0058] Considering the uncertain flow rate of pipeline fluid, this device is recommended to be installed in a horizontal direction: Figure 2 As shown, when the mounting tube 1 is horizontally arranged, the control box 2 is located at the outer top of the mounting tube 1, and the impeller 401 is close to the inner bottom of the mounting tube 1, thereby ensuring that even when the flow rate is small, the fluid can still contact the impeller 401 to achieve energy recovery.

[0059] The control box 2 is provided with a flow detector. The battery is used to supply power to the solenoid valve controller and the flow detector.

[0060] Specifically, the solenoid valve is located outside the control box 2, but the solenoid valve controller can be set inside the control box 2 and electrically connected to the battery. In order for the solenoid valve controller to control the solenoid valve, it is necessary to connect the solenoid valve controller to the solenoid valve through a control wire. In this way, the control box 2 needs to be processed with a wire opening 201 for the control wire to pass through.

[0061] See also Figure 4The flow detector adopts an integrated design, including: a speed sensor and a flow calculator. The speed sensor and the flow calculator are both arranged in the control box 2 and are electrically connected to the battery. The speed sensor is electrically connected to the flow calculator; the speed sensor is arranged on the drive shaft 402 to measure the speed of the drive shaft 402; the flow calculator is used to convert the flow in the pipeline based on the speed of the drive shaft 402.

[0062] The flow detector of the second embodiment can be calibrated in advance: fluids of different flow rates are introduced into the installation pipe 1, and the corresponding rotation speed of the drive shaft 402 is obtained, so as to fit the relationship between the flow rate and the rotation speed. In this way, when it is used later, the rotation speed measured by the rotation speed sensor can be used to convert the flow rate in the pipeline based on the fitted relationship.

[0063] In addition, in order to facilitate users to obtain the conversion results, a wireless communicator can be added to the flow detector. The wireless communicator is electrically connected to the battery. The wireless communicator is electrically connected to the flow calculator and is used to transmit the flow conversion result of the flow calculator to the user end through wireless transmission. The wireless communicator can use one of the wireless communication protocols such as LoRa, Zigbee, Bluetooth, etc., which is selected according to the actual situation on site.

[0064] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
