Description

TECHNICAL FIELD

[0002] With the development of science and technology, fluid flow meters are widely used in many fields such as metallurgy, power, chemical industry, petroleum, transportation, environmental protection and daily life. The accurate measurement of flow meters is very important for improving production efficiency, ensuring production safety, reducing energy waste and fair trade settlement.

[0003] As a national legal measuring instrument, the flow meter is usually detected before leaving the factory to meet the measurement accuracy specified in the national standard or industry standard. However, after the installation and operation of the meter, the accuracy of the meter will change due to factors such as meter fouling, wear and tear, and decay of meter components, resulting in measurement errors or even measurement errors. For example, mechanical water meters will form scale inside the cavity, especially in northern China, which will cause the cavity to shrink, resulting in faster water flow and higher water pressure, causing the impeller to rotate faster, resulting in larger measurement errors, and even unfair trade settlement. However, due to the long-term lack of convenient and effective detection devices and methods for detecting the measurement accuracy of online running water meters, the measurement errors and errors of online running water meters have been ignored for a long time, seriously affecting the fairness of trade settlement. Similarly, oil meters and other fluid flow meters also have similar problems, so there is an urgent need for a portable or easily movable fluid flow meter detection device and method to regularly sample or inspect various online running fluid flow meters to ensure fair trade settlement.

[0054] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements.

[0055] As Figures 1 to 5 shown, the fluid flow meter detection device comprises a connecting joint 10, a standard flow meter 20 and an intelligent component 30.

[0056] The connecting joint 10 is connected with the input end of the standard flow meter 20, the connecting joint 10 is used for connecting the flow meter to be detected 002, the standard flow meter 20 is electrically connected with the intelligent component 30, and the intelligent component 30 is used for acquiring the flow value of the standard flow meter 20 to determine whether the flow meter to be detected 002 is accurate.

[0057] In the embodiment of the present application, since the connecting joint 10 is connected with the input end of the standard flow meter 20, when it is necessary to detect the flow meter to be detected 002, the connecting joint 10 can be directly connected with the flow meter to be detected 002, so that the fluid flowing through the flow meter to be detected 002 can flow into the connecting joint 10 and then flow to the standard flow meter 20 through the connecting joint 10, thereby the standard flow meter 20 can detect the flow of the fluid flowing through the flow meter to be detected 002. Since the standard flow meter 20 is electrically connected with the intelligent component 30, the intelligent component 30 can acquire the measurement value of the standard flow meter 20, and can compare the measurement value with the measurement value of the flow meter to be detected 002 to determine whether the flow meter to be detected 002 is accurate. That is, in the embodiment of the present application, by arranging the standard flow meter 20 and the intelligent component 30, when the standard flow meter 20 detects the fluid flowing through the flow meter to be detected 002, the intelligent component 30 can acquire the measurement value of the standard flow meter 20 in real time, and then can compare the measurement value with the measurement value of the flow meter to be detected 002 to determine whether the flow meter to be detected 002 is accurate. That is, in the embodiment of the present application, the fluid flow meter detection device can conveniently determine whether the flow meter to be detected 002 is accurate or has a fault.

[0058] It should be noted that in actual application, when it is necessary to detect the flow meter to be detected 002, a hose can be connected with the connecting joint 10, and the hose is connected on the outflow pipeline of the flow meter to be detected 002, so that the fluid flowing through the flow meter to be detected 002 can flow to the outflow pipeline, and then can flow to the connecting joint 10 through the hose, and then flow into the standard flow meter 20 through the connecting joint 10, which is equivalent to that the standard flow meter 20 and the flow meter to be detected 002 detect the same fluid, so that the measurement value of the standard flow meter 20 can be acquired by the intelligent component 30, and the intelligent component 30 can determine whether the flow meter to be detected 002 is accurate according to the measurement value of the standard flow meter 20.

[0059] In addition, in the embodiments of the present application, the intelligent component 30 can be a circuit board with control function. Of course, the intelligent component 30 can also be of other types, for example, the intelligent component 30 is a chip with control function, and for another example, the intelligent component 30 is an upper computer with control function. The specific type of the intelligent component 30 is not limited in the embodiments of the present application.

[0060] In addition, in some embodiments, as shown in Figure 4 In addition, in some embodiments, as shown in

[0061] Since the verification component 40 is located at the lower side of the fluid outflow end of the standard flowmeter 20, the standard flowmeter 20 can be verified by the verification component 40, that is, whether the standard flowmeter 20 is accurate is verified by the verification component 40, so that in actual application, when the fluid flowmeter detection device is used to detect the to-be-detected flowmeter 002 in the resident's home, once the resident doubts the detection of the standard flowmeter 20, the standard flowmeter 20 can be detected on site by the verification component 40, so as to ensure the accuracy of the measurement value detected by the standard flowmeter 20, and thus the resident can be convinced of the measurement value detected by the fluid flowmeter detection device.

[0062] In addition, in some embodiments, as shown in Figure 3 or Figure 4 In addition, in some embodiments, as shown in

[0063] Since the containing member 41 is arranged above the weighing member 42, the fluid outflow end of the standard flowmeter 20 is towards the containing member 41, thus, when detecting the flowmeter 002 to be detected, the fluid flowing through the flowmeter 002 to be detected flows through the standard flowmeter 20, and then the fluid outflowing from the standard flowmeter 20 can flow into the containing member 41, and the weighing member 42 can weigh the containing member 41 and the fluid in the containing member 41, to determine the mass of the containing member 41 and the fluid in the containing member 41, and then according to the mass weighed by the weighing member 42, the flow value of the standard flowmeter 20, the measurement time length, and the mass per unit volume of the fluid, to verify whether the standard flowmeter 20 is accurate. The weighing member 42 is electrically connected with the intelligent assembly 30, and the mass weighed by the weighing member 42 can be acquired by the intelligent assembly 30 in real time, and the intelligent assembly 30 can automatically verify whether the standard flowmeter 20 is accurate according to the mass weighed by the weighing member 42. That is, by arranging the containing member 41 and the weighing member 42, it is convenient to determine whether the standard flowmeter 20 is accurate.

[0064] It should be noted that after the intelligent assembly 30 acquires the mass weighed by the weighing member 42, the intelligent assembly 30 can determine the flow rate, flow value and the like of the fluid outflowing from the standard flowmeter 20 according to the mass and the measurement time length, and the flow value determined by the intelligent assembly 30 is accurate, and then the intelligent assembly 30 can compare the determined flow value with the measurement value of the standard flowmeter 20 to determine whether the standard flowmeter 20 is accurate. Specifically, if the flow value determined by the intelligent assembly 30 is equal to the measurement value of the standard flowmeter 20, or the difference between the two is less than or equal to a set threshold value, it indicates that the standard flowmeter 20 is accurate, otherwise, if the difference between the two is greater than the set threshold value, it indicates that the standard flowmeter 20 is inaccurate.

[0065] In addition, in the embodiment of the present application, as shown in Figure 4 The containing member 41 can be further connected with a first valve 140, when the first valve 140 is opened, the fluid in the containing member 41 can flow out of the containing member 41 through the first valve 140, and when the first valve 140 is closed, the fluid in the containing member 41 can be stored in the containing member 41, that is, the fluid in the containing member 41 cannot flow out of the first valve 140.

[0066] Of course, in the embodiment of the present application, the verification assembly 40 can also be of other types, as long as the verification assembly 40 can directly or indirectly determine the flow value of the standard flowmeter, and the specific type of the verification assembly 40 is not limited in the embodiment of the present application.

[0067] In addition, in some embodiments, as shown in Figure 5As shown, the fluid flow meter detection device can further include a mobile frame 50; the mobile frame 50 includes a frame body 51 and rolling wheels 52 connected to the frame body 51, the frame body 51 has a first accommodating member 511 and a second accommodating member 512, in the direction of gravity, the first accommodating member 511 is above the second accommodating member 512; the weighing member 42 is arranged on the second accommodating member 512, and the connecting joint 10, the standard flow meter 20, the pressure gauge 110, the temperature gauge 120 and the intelligent assembly 30 are arranged on the first accommodating member 511.

[0068] Since the weighing member 42 is arranged on the second accommodating member 512, and the connecting joint 10, the standard flow meter 20 and the intelligent assembly 30 are arranged on the first accommodating member 511, it is equivalent that the standard flow meter 20 is above the weighing member 42 in the direction of gravity, that is, the standard flow meter 20 is above the containing member 41, so that when the to-be-detected flow meter 002 is detected, once the fluid flowing through the to-be-detected flow meter 002 flows through the standard flow meter 20, the fluid flowing out of the standard flow meter 20 can directly flow into the containing member 41 by gravity, that is, the fluid flowing out of the standard flow meter 20 can be conveniently flowed into the containing member 41, thereby facilitating the verification of the standard flow meter 20. In addition, the frame body 51 is connected with the rolling wheels 52, so that the frame body 51 can be moved by moving the rolling wheels 52, and the components such as the standard flow meter 20 are moved, so that when the to-be-detected flow meter in the resident's home is detected, the operator can move the mobile frame 50 to move the components such as the standard flow meter 20 to the resident's home for detection.

[0069] It should be noted that the rolling wheels 52 can be universal wheels. In addition, the number of rolling wheels 52 can be set according to actual needs, for example, the number of rolling wheels 52 is 4, and for example, the number of rolling wheels 52 is 8. For this, the embodiments of the present application are not limited here.

[0070] In addition, a fluid hole can be arranged on the first accommodating member 511, the containing member 41 faces the fluid hole, and the fluid outlet end of the standard flow meter 20 faces the fluid hole, so that the fluid flowing out of the standard flow meter 20 can flow into the containing member 41 through the fluid hole.

[0071] In addition, in some embodiments, as shown in Figure 5 As shown, the frame body 51 can be connected with a dragging assembly 60, and the dragging assembly 60 is used to drag the frame body 51 to move.

[0072] Since the frame body 51 is connected with the dragging assembly 60, when the mobile frame 50 needs to be moved, the frame body 51 can be directly dragged to move by the dragging assembly 60. That is, by arranging the dragging assembly 60, the mobile frame 50 can be conveniently moved, and the components such as the standard flow meter 20 can be conveniently moved.

[0073] It should be noted that in the embodiments of the present application, the dragging assembly 60 can be a telescopic dragging assembly. Specifically, the dragging assembly 60 can be formed by an electric telescopic rod. Of course, the dragging assembly 60 can also be formed by a non-electric telescopic rod. Of course, the dragging assembly 60 can also be non-telescopic, that is, the dragging assembly 60 includes a dragging rod, and the dragging rod cannot be telescopic.

[0074] In addition, in some embodiments, as shown in Figure 1 or Figure 3 The fluid flow meter detection device can further include a box 70 and a display module 80. The display module 80 is arranged in the box 70. The connecting joint 10 and the standard flow meter 20 are located in the box 70. The box 70 is provided with a first through hole facing the connecting joint 10. The intelligent assembly 30 is electrically connected with the display module 80.

[0075] Since the display module 80 is arranged in the box 70, and the intelligent assembly 30 is electrically connected with the display module 80, the intelligent assembly 30 can control the display module 80 to display, so that the display module 80 can display corresponding information, for example, the display module 80 displays information about whether the standard flow meter 20 is accurate, and for another example, the display module 80 displays the mass weighed by the weighing piece 42. In addition, the angle of the display module 80 relative to the box 70 can be adjusted according to actual needs, so that the operator can see the content displayed by the display module 80.

[0076] In addition, in the embodiments of the present application, the display module 80 can be movable relative to the box 70, and the display module 80 can also be covered on the box 70, that is, when the fluid flow meter detection device is not needed, the display module 80 is covered on the box 70, that is, the display module 80 is in contact with the box 70. When the fluid flow meter is used, the display module 80 is unfolded, that is, the display module 80 is away from the box 70, so that the operator can watch the display module 80. Of course, the display module 80 can also be fixed on the box 70.

[0077] In addition, the connecting joint 10 and the standard flow meter 20 are located in the box 70, so that the operator can directly move the standard flow meter 20 and other components to the required position by carrying the box 70, and the box 70 can protect the standard flow meter 20, avoiding the problem that the standard flow meter 20 can be easily damaged. In addition, the box 70 is provided with a first through hole facing the connecting joint 10. Through such a design, when the to-be-detected flow meter 002 needs to be detected, the connecting joint 10 can be directly connected with the to-be-detected flow meter 002, avoiding the problem that the connecting joint 10 is blocked and not easy to connect.

[0078] It should be noted that in the embodiments of the present application, the display module 80 can be an LED display screen, of course, the display module 80 can also be of other types, for example, the display module 80 is an LCD display screen. The specific type of the display module 80 is not limited in the embodiments of the present application.

[0079] In addition, in the embodiments of the present application, the display module 80 and the box body 70 can be hingedly connected, so that the display module 80 is movable relative to the box body 70.

[0080] In addition, in the embodiments of the present application, the connecting joint 10 can be flush with the outer wall of the box body 70, that is, the box body 70 can have a recess, the bottom of the recess is provided with a first through hole, the connecting joint 10 can pass through the first through hole, and the connecting joint 10 is located in the recess and flush with the outer wall of the box body 70, or the connecting joint 10 is recessed in the recess, which can effectively avoid the problem that the connecting joint 10 protrudes from the outer wall of the box body 70, causing the connecting joint 10 to be easily damaged.

[0081] In addition, in the embodiments of the present application, the smart component 30 can be located in the box body 70, so that the box body 70 can protect the smart component 30, avoiding the problem that the smart component 30 is easily damaged.

[0082] In addition, in some embodiments, as shown in Figure 1 The box body 70 is movably connected with a box cover 71, the display module 80 is fixed to the surface of the box cover 71 facing the box body 70, and the box cover 71 can drive the display module 80 to move relative to the box body 70.

[0083] Since the display module 80 is fixed to the surface of the box cover 71 facing the box body 70, and the box body 70 is movably connected with the box cover 71, the box cover 71 can be moved to drive the display module 80 to move, that is, the display module 80 is movable relative to the box body 70. Specifically, in actual application, if the fluid flow meter detection device is not needed, the box cover 71 can be closed on the box body 70, and the box cover 71 can protect the display module 80, avoiding the problem that the display module 80 is easily damaged; when the fluid flow meter detection device is needed, the box cover 71 can be opened, which is equivalent to unfolding the display module 80 relative to the box body 70, and the operator can watch the content displayed on the display module 80.

[0084] It should be noted that the box cover 71 and the box body 70 can be connected by a hinge, so that the box cover 71 is movable relative to the box body 70.

[0085] In addition, in some embodiments, as shown in Figure 3As shown, the fluid flow meter detection device can further include an input module 90, the input module 90 is arranged on the outer wall of the box 70, and the input module 90 is electrically connected with the intelligent component 30, and the input module 90 is used for inputting information and instructions to the intelligent component 30.

[0086] Since the input module 90 is arranged on the outer wall of the box 70, and the input module 90 is electrically connected with the intelligent component 30, when the fluid flow meter detection device is used, the operator can input information and instructions to the intelligent component 30 through the input module 90, so that the intelligent component 30 performs corresponding control. That is, by arranging the input module 90, the operator can input information and instructions to the intelligent component 30.

[0087] It should be noted that the input module 90 can be an input keyboard.
