[0029] Drainage pipes refer to the system composed of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater; including trunk pipes, branch pipes and pipes leading to treatment plants. No matter whether they are built on the streets or anywhere else, as long as they are pipes that serve the purpose of drainage, they should be counted as drainage pipes. The drainage network composed of drainage pipes is the drainage network. In order to calculate whether the pollution load of the water body exceeds the environmental capacity and evaluate the control effect, and to grasp the total amount of pollutants discharged by the pollution source and the amount of drainage, it is necessary to monitor the flow of water in the drainage pipe. The traditional method is mainly to monitor water bodies through ultrasonic detectors or radar detectors. However, when using ultrasonic detectors or radar detectors to monitor water bodies, there will be monitoring blind spots, which makes it impossible to conduct comprehensive monitoring.

[0030] Based on the above considerations, in order to solve the problem of blind spots in water body monitoring in related technologies, a flow meter is designed. The radar liquid measuring device and the ultrasonic liquid measuring device arranged on the flow meter can be used to monitor the water body alone, or the radar liquid measuring device and the ultrasonic liquid measuring device can be used to monitor the water body at the same time; and the radar water level probe is set on the first working surface, and the ultrasonic probe is set on the second working surface. Since the orientation of the first working surface and the orientation of the second working surface intersect, the monitoring range of the radar water level probe and the monitoring range of the ultrasonic probe can form an intersection, thereby effectively reducing the blind spots generated when the radar liquid measuring device and the ultrasonic liquid measuring device are used alone, and effectively improving the monitoring effect of the water body.

[0031] Below, the flow meter of the embodiment of the present application will be described in detail according to specific implementation methods.

[0032] Please refer to Figures 1 to 3 The embodiment of the present application provides a flow meter 100, including a substrate 10, a radar liquid measuring device 30 and an ultrasonic liquid measuring device 20; the substrate 10 has a first working surface 11 and a second working surface 12, and the orientation of the first working surface 11 and the orientation of the second working surface 12 intersect; the radar liquid measuring device 30 is arranged on the substrate 10, and the radar liquid measuring device 30 includes a radar water level probe 31, and the radar water level probe 31 is arranged on the first working surface 11; the ultrasonic liquid measuring device 20 is arranged on the substrate 10, and the ultrasonic liquid measuring device 20 includes an ultrasonic probe 21, and the ultrasonic probe 21 is arranged on the second working surface 12.

[0033] The base 10 is the main body of the flow meter 100 and is used for assembly and connection of other components.

[0034] Among them, the first working surface 11 and the second working surface 12 are two different end surfaces on the substrate 10; the orientation of the first working surface 11 refers to the direction perpendicular to the first working surface 11 and toward the outside of the substrate 10; the orientation of the second working surface 12 refers to the direction perpendicular to the second working surface 12 and toward the outside of the substrate 10.

[0035] The orientation of the first working surface 11 intersects with the orientation of the second working surface 12 , which means that a direction perpendicular to the first working surface 11 and toward the outside of the substrate 10 intersects with a direction perpendicular to the second working surface 12 and toward the outside of the substrate 10 .

[0036] The radar liquid measuring device 30 is a device that uses radar technology to measure water bodies; the radar liquid measuring device includes a radar water level probe 31, which can emit electromagnetic waves and receive reflected signals to measure the liquid level. The radar water level probe 31 is arranged on the first working surface 11, so that the radar water level probe 31 can emit electromagnetic waves outward on the first working surface 11 and receive reflected signals to monitor the water level.

[0037] The ultrasonic liquid measuring device 20 is a device that uses ultrasonic technology to measure the liquid level; the ultrasonic liquid measuring device 20 includes an ultrasonic probe 21, and the ultrasonic probe 21 measures the liquid level by emitting and receiving ultrasonic waves. The ultrasonic probe 21 is arranged on the second working surface 12, so that the ultrasonic probe 21 can emit and receive ultrasonic waves outward on the second working surface 12 to monitor the water level.

[0038] It can be understood that when the flow meter 100 is used to monitor the drainage pipe, the radar water level probe 31 can be used alone for monitoring. For example, when the water body in the drainage pipe is in a half-pipe state (that is, the water level is lower than the state of the radar water level probe 31), the radar water level probe 31 can be used to monitor the water level; or, the ultrasonic probe 21 can be used alone for monitoring. For example, when the water body in the drainage pipe is in a full pipe state (that is, the water level is higher than the state of the ultrasonic probe 21), the ultrasonic probe 21 can be used to monitor the water level; or, no matter what state the water body in the drainage pipe is in, the ultrasonic probe 21 and the radar water level probe 31 can be used simultaneously to jointly implement the monitoring operation.

[0039] The flow meter 100 provided in the embodiment of the present application includes a base 10 and a radar liquid measuring device 30 and an ultrasonic liquid measuring device 20 arranged on the base 10. The radar liquid measuring device 30 and the ultrasonic liquid measuring device 20 can be used to monitor the water body alone, or the radar liquid measuring device 30 and the ultrasonic liquid measuring device 20 can be used to monitor the water body at the same time; and the radar water level probe 31 is set on the first working surface 11, and the ultrasonic probe 21 is set on the second working surface 12. Since the orientation of the first working surface 11 and the orientation of the second working surface 12 intersect, the monitoring range of the radar water level probe 31 and the monitoring range of the ultrasonic probe 21 can form an intersection, thereby effectively reducing the blind spot generated when the radar liquid measuring device 30 and the ultrasonic liquid measuring device 20 are used alone, and effectively improving the monitoring effect of the water body.

[0040] Please refer to Figures 1 to 3 In some embodiments, the base 10 further includes a third working surface 13, and opposite ends of the third working surface 13 are respectively connected to the first working surface 11 and the second working surface 12; the third working surface 13 is arranged to be inclined.

[0041] The third working surface 13 is used to connect the first working surface 11 and the second working surface 12 . The third working surface 13 is an intermediate transition surface between the first working surface 11 and the second working surface 12 .

[0042] It can be understood that the third working surface 13 is set to be inclined, that is, the third working surface 13 is inclined relative to the horizontal plane. When the water body flows toward the third working surface 13, the third working surface 13 can drain the water body to reduce the silt and sewage in the water body so that it can flow more smoothly without stopping, thereby reducing the impact of impurities in the water body on the flow meter 100.

[0043] Please refer to Figures 1 to 3 In some embodiments, the radar liquid measuring device 30 further includes a radar speed measuring module (not shown in the figure), which is disposed in the base 10 , and the sensing end of the radar speed measuring module faces the third working surface 13 .

[0044] The radar speed measurement module is used to measure the flow rate of water. The radar speed measurement module can emit electromagnetic waves and receive the signal reflected from the flowing water through the sensing end to monitor the flow rate of the water.

[0045] In this configuration, the radar liquid measuring device 30 also includes a radar speed measuring module, so that while monitoring the water level of the water body, it can also monitor the flow rate of the water body, effectively improving the monitoring range of the flow meter 100, and further improving the application range of the flow meter 100.

[0046] Please refer to Figures 1 to 3 In some embodiments, the first working surface 11, the second working surface 12 and the third working surface 13 are located on the same side of the base 10; in the gravity direction G, the first working surface 11, the third working surface 13 and the second working surface 12 are arranged in sequence.

[0047] Among them, the first working surface 11, the second working surface 12 and the third working surface 13 are located on the same side of the base 10, so that the radar water level probe 31, the ultrasonic probe 21, and the radar speed measurement module can monitor the water body on the same side of the base 10. At the same time, the first working surface 11, the third working surface 13 and the second working surface 12 are arranged in sequence along the gravity direction G, that is, the first working surface 11 is located at the top in the gravity direction G, and the radar water level probe 31 arranged on the first working surface 11 can emit electromagnetic waves at the upper part of the base 10 in the gravity direction G; the ultrasonic probe 21 can emit ultrasonic signals at the lower part of the base 10 in the gravity direction G, so as to monitor the water body more comprehensively, thereby effectively reducing the blind area of ​​the flow meter 100.

[0048] Please refer to Figures 1 to 3In some embodiments, the first working surface 11 faces the gravity direction G, and the third working surface 13 faces the horizontal direction M.

[0049] It should be understood that the gravity direction G and the horizontal direction M are perpendicular to each other.

[0050] It can be understood that the first working surface 11 faces the gravity direction G. Optionally, the normal of the first working surface 11 can be parallel to the gravity direction G, or the normal of the first working surface 11 can form an acute angle with the gravity direction G. When the radar water level probe 31 is arranged on the first working surface 11, the radar water level probe 31 can face the gravity direction G and emit electromagnetic waves more comprehensively around, which effectively improves the monitoring range of the radar water level probe 31.

[0051] The third working surface 13 faces the horizontal direction M. Optionally, the normal of the third working surface 13 may be parallel to the horizontal direction M, or the normal of the third working surface 13 may form an acute angle with the horizontal force direction. When the ultrasonic probe 21 is arranged on the third working surface 13, the ultrasonic probe 21 can transmit and receive ultrasonic waves in the horizontal direction M to achieve the purpose of monitoring the water body.

[0052] Please refer to Figures 1 to 3 In some embodiments, the normal of the third working surface 13 forms an angle α with the horizontal direction M, wherein -3°≤α≤3°.

[0053] It should be understood that the normal direction of the third working surface 13 refers to a direction perpendicular to the third working surface 13 .

[0054] The angle α formed by the normal of the third working surface 13 and the horizontal direction M is limited to between -3° and 3°; illustratively, the angle α formed by the normal of the third working surface 13 and the horizontal direction M can be but is not limited to -3°, -2°, -1°, 0°, 1°, 2°, 3°, etc.

[0055] With such a configuration, the third working surface 13 can play a role in diverting the water body and reducing the accumulation of sewage, silt, etc. in the water body; at the same time, by adjusting the angle α between the normal of the third working surface 13 and the horizontal direction M, the monitoring range between the ultrasonic probe 21 and the radar water level probe 31 can be further adjusted to improve the monitoring range of the flow meter 100.

[0056] Please refer to Figures 1 to 3 In some embodiments, a guide groove 131 is provided on the third working surface 13 , and the guide groove 131 is connected to the outside along the gravity direction G.

[0057] Optionally, the number of the guide grooves 131 may be one, two, or any number greater than two.

[0058] The guide groove 131 is connected to the outside along the gravity direction G; with such a configuration, when impurities such as silt in the water body flow to the third working surface 13, the guide groove 131 can guide the silt and other impurities from the guide groove 131 along the gravity direction G to the outside of the third working surface 13, further reducing the accumulation of silt, thereby further reducing the monitoring impact of silt on the flow meter 100.

[0059] Please refer to Figures 1 to 3 In some embodiments, the base 10 also includes a fourth working surface 14, which is connected to the third working surface 13, and the fourth working surface 14 faces the gravity direction G; a mounting hole 141 is opened on the fourth working surface 14, and at least one of a water temperature sensor (not shown in the figure) and a pressure detector (not shown in the figure) is arranged in the mounting hole 141.

[0060] Optionally, the fourth working surface 14 may be the bottom surface of the base body 10 located at the bottommost side in the gravity direction G.

[0061] The fourth working surface 14 is provided with a mounting hole 141. Optionally, the number of the mounting holes 141 may be one, two, or more than two. A water temperature sensor may be arranged in the mounting hole 141 to monitor the water temperature of the water body; or a pressure detector may be arranged in the mounting hole 141 to monitor the water pressure of the water body; or a water temperature sensor and a pressure sensor may be arranged in the mounting hole 141 to monitor the temperature and pressure of the water body at the same time.

[0062] Please refer to Figures 1 to 3 In some embodiments, the substrate 10 includes a shell 101, an end cover 102 and a waterproof rubber ring (not shown in the figure), the end cover 102 is sealed on the shell 101, and the waterproof rubber ring is clamped between the end cover 102 and the shell 101.

[0063] The base 10 includes a housing 101 and an end cover 102. Various components can be installed and accommodated in the housing 101, and the end cover 102 is covered on the housing 101 to achieve sealing. The base 10 also includes a waterproof rubber ring, which is sandwiched between the end cover 102 and the housing 101. Therefore, when the end cover 102 and the housing 101 are covered, the waterproof rubber ring can fill the gap between the end cover 102 and the housing 101, thereby further improving the sealing performance between the end cover 102 and the housing 101.

[0064] Please refer to Figures 1 to 3 In some embodiments, the housing 101 is further provided with a connection hole 103 for plugging in the power cord 40 , and the connection hole 103 is filled with sealant.

[0065] It can be understood that the connection hole 103 is used for plugging the power cord 40 to electrically connect components such as the radar liquid measuring device 30 and the ultrasonic liquid measuring device 20. By filling the connection hole 103 with sealant, the sealant can fill the gap between the power cord 40 and the connection hole 103, thereby effectively improving the sealing of the connection hole 103.

[0066] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
