Description

Technical Field

[0001] The utility model belongs to the technical field of wind speed transmitters, and in particular relates to a laminar flow wind speed transmitter. Background Art

[0002] Wind speed transmitter is an instrument used to measure wind speed. It converts the physical quantity of wind speed into an electrical signal for use in industrial control systems or environmental monitoring equipment. Wind speed transmitters usually use mechanical or electronic sensors to detect wind speed and convert the detected wind speed information into standard current or voltage signals that can be recognized and processed by automation systems.

[0003] In current technical applications, laminar flow wind speed transmitter is a common instrument used to accurately measure the flow rate of fluid. However, when using this device, we usually encounter an inconvenience: the installation angle of the transmitter needs to be manually adjusted. This step not only increases the complexity of the operation, but also consumes extra time and manpower. This situation is particularly inconvenient in practical applications, especially in environments that require frequent adjustments or monitoring. Therefore, seeking a laminar flow wind speed transmitter that can automatically adjust the installation angle has become a direction of technical improvement in order to improve work efficiency and accuracy. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a laminar flow wind speed transmitter to solve the problem that the traditional laminar flow wind speed transmitter proposed in the above background technology requires manual adjustment of the installation angle of the transmitter. This step not only increases the complexity of the operation, but also consumes additional time and manpower. This situation is particularly inconvenient in practical applications, especially in environments that require frequent adjustment or monitoring.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a laminar wind speed transmitter, comprising a main structure, one side surface of the main structure is rotatably connected to a connecting structure via a second rotating shaft, the upper end of the connecting structure is rotatably connected to a first rotating shaft, the upper end of the first rotating shaft is rotatably connected to a wind cup, three wind cups are provided, the surface of the first rotating shaft is fixedly connected to a rotating disk, the surface of the rotating disk is penetrated by a positioning hole, the upper end of the one side surface of the main structure is fixedly connected to a telescopic rod, the output end of the telescopic rod is equipped with a connecting plate, the outer surface of the connecting plate is fixedly connected to a handle via a connecting rod, a spring structure is provided between the inner surface of the connecting plate and the side surface of the main structure, and one end of the inner surface of the connecting plate is fixedly connected to a positioning column.

[0006] Preferably, a display panel is installed on the upper end of one side surface of the main structure, and a display screen is installed on the surface of the display panel.

[0007] Preferably, the display panel is fixedly mounted on the surface of the main structure by means of mounting bolts.

[0008] Preferably, a control switch and a knob are respectively installed on the lower end of one side surface of the main structure.

[0010] Preferably, a plurality of positioning holes are provided.

[0011] Preferably, the cross-sectional shapes and sizes of the positioning holes and the positioning posts are equal.

[0012] Compared with the prior art, the utility model provides a laminar flow wind speed transmitter, which has the following beneficial effects:

[0013] 1. The utility model provides a first rotating shaft and a second rotating shaft. When in use, the wind cup senses the direction of the wind force, and the direction and angle of the structure at the wind cup are automatically adjusted by the first rotating shaft and the second rotating shaft, so as to automatically adjust the angle at which the laminar flow wind speed transmitter senses the wind force. This is more convenient and quicker than the traditional manual adjustment of the angle of the transmitter, and effectively avoids the need for the traditional laminar flow wind speed transmitter to manually adjust the installation angle of the transmitter. This step not only increases the complexity of the operation, but also consumes extra time and manpower. This situation is particularly inconvenient in practical applications, especially in environments that require frequent adjustment or monitoring.

[0014] 2. The utility model is provided with a positioning hole and a positioning column. When the wind cup senses the wind angle, the positioning column is pulled outward by the handle. At this time, the spring structure is in a stretched state. When the angle adjustment of the wind cup structure is completed, the handle is released, and the spring structure is reset. The positioning column slides toward the positioning hole through the reset elastic force of the spring structure, and the positioning column is connected to the inside of the positioning hole through the snap connection of the positioning column, thereby fixing the rotation angle at the second rotation axis;

[0015] 3. The utility model provides a handle to facilitate the use of the handheld laminar flow wind speed transmitter, and provides a knob and a control switch to facilitate the adjustment and debugging of the laminar flow wind speed transmitter, so as to more accurately measure the wind force and wind speed.
