Description

Technical Field

[0001] This utility model relates to the field of heat energy metering, and in particular to a heat metering system. Background Technology

[0002] In the heating industry, the current mainstream method for flow detection is to install turbine flow sensors on the pipeline. When the medium in the pipeline passes through the turbine sensor, it drives the turbine to rotate. The flow velocity of the medium in the pipeline is indirectly calculated by detecting the turbine speed.

[0003] To ensure accurate measurement, turbine flow sensors require that the medium passing through them be in a laminar flow state. Therefore, there are strict requirements for the installation location of eddy current sensors. They cannot be placed in bends, diameter changes, or other similar locations. In addition, it is necessary to ensure that the pipe diameter meets the requirements of the eddy current sensor.

[0004] The installation of eddy current sensors requires the system to be shut down before pipe cutting and welding can be performed, which is inconvenient and the shutdown of the entire system will affect the heating supply. This needs to be improved. Utility Model Content

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 , Figure 2 As shown, a heat metering system includes a mounting clip 1, a pair of clamps 2, an external flow sensor 3, and an external temperature sensor 4.

[0026] like Figure 1 , Figure 2 As shown, the mounting clip 1 is used to clamp and fix the pipe to the outside, and a pair of clamping plates 2 are arranged in an arc shape on the mounting clip 1 and are used to clamp the two sides of the pipe.

[0027] like Figure 1 , Figure 2 As shown, the external flow sensor 3 is embedded in the middle of a pair of clamps 2 and is used to fit against the outer wall of the pipe. One pair of external flow sensors 3 is a transmitter and receiver, one is responsible for transmitting ultrasonic signals and the other is responsible for receiving ultrasonic signals. When working, it measures the time difference of ultrasonic waves in the pipe liquid with and against the flow based on the time difference method, and converts the time information into velocity information through signal processing, and then converts it into the flow information corresponding to the fluid in the pipe.

[0028] like Figure 1 , Figure 2 As shown, the external temperature sensor 4 is embedded at both ends of a pair of clamps 2 and is used to fit the outer wall of the pipe. The external temperature sensor 4 preferably uses a PT1000 temperature probe to improve the stability of temperature measurement.

[0029] Therefore, when measuring the thermal energy of the medium in the pipeline, the mounting clip 1 is fixed to the outer wall of the pipeline, and a pair of clamps 2 are clamped and attached to both sides of the pipeline, so that the external flow sensor 3 and the external temperature sensor 4 are in contact with the outer wall of the pipeline, thereby realizing the detection of the flow rate and temperature of the medium in the pipeline.

[0030] Therefore, by setting up the combination of external flow sensor 3 and external temperature sensor 4, the flow rate and temperature of the medium in the pipeline can be conveniently measured, thereby enabling accurate and real-time measurement of heat energy without damaging the pipeline, stopping the machine, or interfering with the flow of heat energy.

[0031] In practical use, data collectors, data processors, network modules, backend servers, and cloud platform user interfaces can also be added.

[0032] The data acquisition unit receives flow data from the external flow sensor 3 and temperature data from the external temperature sensor 4. The data processor integrates and verifies the data received by the data acquisition unit. The network module connects to the backend server of the online flow meter and transmits the data processed by the data processor to the backend server via the network. The backend server stores the data returned by the network module. The cloud platform user interface displays the metering results and provides user interaction. Users can view heat flow data, historical records, and other information, and perform related operations through the interface.

[0033] like Figure 1 , Figure 2 As shown, the mounting clip 1 includes a handle 11, a pair of clamping rods 12, and a drive mechanism 5. Recording cards 13 and recording pens 14 are provided on both sides of the handle 11 for convenient manual recording of values ​​and data from subsequent tests, facilitating the tracking of measurement time and cycle.

[0034] like Figure 1 , Figure 2 As shown, a pair of clamping rods 12 are rotatably connected to the end of the handle 11 and distributed on both sides of the handle 11. A pair of clamping plates 2 are rotatably connected to the clamping rods 12 to adjust the angle position of the clamping plates 2 and achieve stable clamping of the pipe.

[0035] like Figure 1 , Figure 2 As shown, the drive mechanism 5 is disposed within the handle 11 and is used to control the pair of clamping rods 12 to move closer or further apart. The drive mechanism 5 includes a rack 51, a pair of gears 52, and a drive member 53. The rack 51 is slidably connected within the handle 11, and the pair of gears 52 are disposed at the rotating ends of the pair of clamping rods 12 and mesh with the rack 51.

[0036] like Figure 1 , Figure 2 As shown, the drive unit 53 is used to control the sliding and fixing of the rack 51. The drive unit 53 includes a screw 54 and a handwheel 55. The screw 54 is threaded to the handle 11 and rotatably connected to the rack 51. The handwheel 55 is located at the outer end of the screw 54.

[0037] like Figure 1 , Figure 2 As shown, a pair of clamping rods 12 are rotatably connected to a locking rod 6 at the middle position. One locking rod 6 has a threaded head 61 threaded to its end, and the other locking rod 6 has a threaded tube 62 for the threaded head 61 to be screwed into its end.

[0038] When it is necessary to measure the medium inside the pipeline, the control handwheel 55 drives the screw 54 to rotate. At this time, the screw 54 controls the rack 51 to slide, and the rack 51 drives the gear 52 and the clamping rod 12 to rotate. The clamping rod 12 drives the clamping plate 2 to move synchronously, so that the clamping plate 2 clamps and fits against the outer wall of the pipeline. Since the screw 54 is driving, it can automatically lock, thereby fixing the rack 51 and indirectly fixing the entire mounting clamp 1.

[0039] Subsequently, the pair of locking rods 6 can be rotated and aligned. Then, the threaded head 61 can be rotated to control the extension and retraction of the threaded head 61 and screw the threaded head 61 into the threaded tube 62, thereby tightening and fixing the pair of clamping rods 12, achieving secondary locking and increasing stability during use.

After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
