DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] It should be noted that, in the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0020] It should be noted that the architecture described in the embodiment of the utility model is for more clearly illustrating the technical solution of the embodiment of the utility model, and does not constitute a limitation on the technical solution provided by the embodiment of the utility model. Ordinary technicians in this field can know that with the evolution of related industry technologies and the emergence of other equipment, the technical solution provided by the embodiment of the utility model is also applicable to similar technical problems.

[0021] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0022] In the field of measurement and control, flowmeter is a commonly used measuring device, which is an instrument used to measure the total amount of fluid within a selected time interval. Simply put, it is an instrument used to measure the flow rate of fluid in a pipeline or open channel. At present, there are generally two types of power supply methods for flowmeters in the industry, namely external power supply and built-in battery.

[0023] However, the external power supply solution needs to maintain continuous power supply, and long-term power supply will obviously cause energy waste. Also, the built-in battery solution requires frequent replacement of the flow meter's built-in dry batteries, which results in the flow meter being forced to interrupt its operation when the flow meter's dry batteries are insufficient or when the flow meter's batteries are replaced, which can easily cause the loss of flow data. In summary, the industry has not yet been able to provide a flow meter that does not require long-term external power supply and frequent replacement of dry batteries.

[0024] Therefore, in order to solve the above problems existing in the industry, the utility model proposes an energy-saving mass flow meter, which can use the flow of fluid in the pipeline to power itself for continuous operation.

[0025] In this way, when the mass flow meter provided by the utility model is working, the staff does not need to provide an external power supply for the mass flow meter, saving power loss; at the same time, there is no need to provide an internal dry battery for the mass flow meter, avoiding problems such as operation interruption and data loss caused by the exhaustion of dry battery power or replacement of dry battery. The mass flow meter provided by the utility model does not need to consider its energy supply problem once it is set up, realizing energy saving in the operation of the mass flow meter and bringing great convenience to the detection of mass flow.

[0026] The utility model provides an energy-saving mass flow meter, which comprises a flow measurement unit 1 , an energy recovery unit 2 , and a power storage unit 3 .

[0027] In one example, Figure 1 As shown, in the energy-saving mass flow meter provided by the utility model:

[0028] The flow measurement unit 1 is used to measure and display the flow conditions of the fluid in the pipeline.

[0029] Specifically, the flow measurement unit 1 can be divided into two parts: a measuring component 101 and a display component 102. The measuring component 101 is arranged in the pipeline; the display component 102 is arranged outside the pipeline and located above the measuring component 101, and can display the flow of the fluid in the pipeline.

[0030] It is understandable that the measuring component 101 can be implemented as an electromagnetic flowmeter, a turbine flowmeter, a mechanical flowmeter, an ultrasonic flowmeter, or other devices with a flow measurement function in actual applications.

[0031] The display component 102 may be an electronic display screen, a counter, a counting instrument, or other display devices capable of indicating the data currently detected by the measuring component 101 in actual applications, and the present invention does not make any specific limitation on this.

[0032] And, the energy recovery unit 2 is used to recover the kinetic energy inside the fluid pipeline and convert the kinetic energy into electrical energy and store it in the connected power storage unit 3. The energy recovery unit 2 specifically includes a transmission device 201 and a power generation device 202.

[0033] Optionally, the power generation device 202 may be implemented as a generator in actual applications.

[0034] For example, Figure 2As shown, the transmission device 201 can be divided into a rotating wheel 2011 and a transmission rod 2012 .

[0035] The impeller 2011 is arranged at the lower part of the inner cavity of the fluid pipeline. The impeller 2011 can rotate driven by the fluid flow and convert the kinetic energy of the fluid flow into electrical energy through the transmission rod 2012 and the power generation device 202 connected thereto.

[0036] One end of the transmission rod 2012 is connected to the rotating wheel, and the other end is connected to the power generation device. In addition, the transmission rod 2012 penetrates the fluid pipeline to connect to the power generation device 202 outside the pipeline.

[0037] The sub-units included in the energy recovery unit 2 are introduced above.

[0038] The power storage unit 3 is used to supply power to the mass flow meter. The connection between the power storage unit 3 and the mass flow meter is an electrical connection, and the connection between the power storage unit 3 and the power generation device 202 is also an electrical connection.

[0039] Specifically, the power storage unit 3 may be a battery pack in practical applications, or other equipment with charging and discharging functions, which is not specifically limited in the present invention.

[0040] It can be understood that after the impeller 2011 rotates driven by the fluid flow and converts the kinetic energy of the fluid flow into electrical energy through the transmission rod 2012 and the power generation device 202 connected thereto, the power storage unit 3 can store the converted electrical energy through the electrical connection with the power generation device 202 to continuously power the mass flow meter.

[0041] And, the electric control valve 4 is arranged on the fluid pipeline and located upstream of the measuring component 2 .

[0042] The electric control valve 4 is used to block the flow of the fluid in the pipeline when the flow is abnormal; or, after the staff eliminates the fault and the abnormal flow is eliminated, restore the flow of the fluid in the pipeline.

[0043] It is understandable that a control switch may be provided on the body of the electric-controlled valve 4 , or the electric-controlled valve 4 may be communicatively connected with a remote control device, so that a worker may remotely control the electric-controlled valve 4 to open or close.

[0044] Based on the above technical solution, the energy-saving mass flow meter provided by the utility model can use the flow of fluid in the pipeline to power itself for continuous operation. In this way, when the mass flow meter provided by the utility model is working, there is no need to provide an external power supply for the mass flow meter, saving power loss; at the same time, there is no need to provide an internal dry battery for the mass flow meter, avoiding problems such as operation interruption and data loss caused by the exhaustion of dry battery power or replacement of dry battery. The mass flow meter provided by the utility model does not need to consider its energy supply problem once it is set up, which realizes energy saving in the operation of the mass flow meter and brings great convenience to the detection of mass flow.

[0045] In another example, Figure 3 As shown, the energy-saving mass flow meter provided by the utility model may further include: a local alarm module 5.

[0046] The local alarm module 5 is connected to the energy recovery unit 2 and is arranged on one side of the flow measurement unit 1 for local alarm. It should be noted that the alarm mode of the local alarm module 5 can be sound and light alarm or other alarm modes, which is not limited in the present invention.

[0047] That is to say, when the flow of the fluid in the pipeline is abnormal, the local alarm module 5 will also, under the control of the energy recovery unit 2, issue an alarm on one side of the flow measurement device to ensure that when there are no remote staff, the on-site staff can notice the abnormal flow of the pipeline here.

[0048] In a possible implementation, the energy-saving mass flowmeter provided by the utility model further includes a master control switch and a sub-control switch.

[0049] Among them, the master control switch is used to control the power on or off of the mass flow meter to save energy.

[0050] Sub-control switches are used to control the operation of various components in the mass flow meter to save energy.

[0051] Optionally, the sub-control switches can be divided into flow measurement unit 1 control switch, energy recovery unit 2 control switch, power storage unit 3 control switch, electric control valve 4 control switch, and local alarm module 5 control switch, which respectively control the opening or closing of the flow measurement unit 1, energy recovery unit 2, power storage unit 3, electric control valve 4, and local alarm module 5.

[0052] It should be pointed out that Figure 1 , Figure 2 , Figure 3 The composition structure shown in the figure does not constitute a limitation on the energy-saving mass flow meter, except Figure 1 , Figure 2, Figure 3 In addition to the components shown, the energy-saving mass flow meter may include more or fewer components than shown, or combine certain components, or arrange the components differently.

[0053] It should be noted that the terms "first" and "second" in the specification, claims and drawings of the utility model are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0054] It should be understood that in the present utility model, "at least one (item)" means one or more, "more than one" means two or more, "at least two (items)" means two or three and more than three, and "and / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist at the same time, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or plural.

[0055] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
