Description

Technical Field

[0001] This utility model relates to the field of meteorological equipment technology, and in particular to a cleaning device for a forced ventilation temperature measuring instrument. Background Technology

[0002] With the development of environmental monitoring technology, forced ventilation temperature measuring instruments have emerged. These instruments are characterized by their high efficiency and accuracy in measuring temperature, and have thus become an important device in the field of meteorological monitoring.

[0003] In related technologies, when forced ventilation temperature measuring instruments are used in the field, more and more dust will accumulate at the air inlet. Under long-term accumulation, the dust becomes very difficult to remove. At the same time, when the dust accumulates to a certain extent, it will affect the ventilation effect. The ventilation speed at the sensor sensing part will be lower than the minimum wind speed, affecting the functional requirements of the measuring instrument. Therefore, in order to maintain the measurement accuracy of forced ventilation temperature measuring instruments, the accumulated dust is usually removed by manually wiping the external air inlet regularly.

[0004] However, the above-mentioned manual wiping method has the problems of being cumbersome, time-consuming and labor-intensive, and difficult to guarantee the wiping frequency and effect. Utility Model Content

[0005] In response to the shortcomings of the existing production technology, the applicant provides a cleaning device for a forced ventilation temperature measuring instrument, thereby replacing manual operation with automatic operation, effectively cleaning dust, avoiding manual operation, improving maintainability, and enhancing the product quality of meteorological observation equipment.

[0010] The transmission mechanism includes a disc, a connecting rod, and a guide member. One end of the connecting rod is connected to the outer surface of the disc, and the other end is connected to a brush holder, forming a crank-slider structure.

[0011] The driving component is connected to the disk via the driving end and is used to drive the disk to rotate via the connecting rod to drive the brush holder to reciprocate linearly along the guide, so that the brush performs reciprocating linear cleaning motion relative to the filter element.

[0012] As a further improvement to the above technical solution:

[0013] Preferably, it also includes an air inlet housing, which is disposed at the bottom of the cleaning mechanism, and the bottom surface of the air inlet housing has at least one air inlet.

[0014] More preferably, the number of air inlets is multiple and evenly distributed on the bottom surface of the air inlet housing, in order to prevent operators from accidentally injuring themselves by the transmission mechanism when they put their hands into the air inlet housing during the transmission process.

[0015] Preferably, it also includes an installation mechanism, which includes a first installation block and a second installation block, which cooperate to form a clamp structure to surround and fix to the outer wall of the forced ventilation temperature measuring instrument, and the bottom of the first installation block is fixedly connected to the drive component.

[0016] Preferably, an adjustment element is provided vertically on the first mounting block. The adjustment element is used to adjust the vertical position of the first mounting block to change the distance between the brush and the filter element, thereby adjusting the cleaning force.

[0017] Preferably, the adjusting component is an adjusting bolt, which adjusts the vertical position of the first mounting block through threaded engagement.

[0018] Preferably, the guide component is a linear module, fixed on a guide mounting base, which is located below the disc.

[0019] Preferably, the filter element is configured as a screen structure;

[0020] More preferably, the mesh size of the sieve structure is 8 mesh.

[0021] Preferably, the driving component is a stepper motor or a servo motor, and the output shaft of the driving component is coaxially connected to the disk.

[0022] The beneficial effects of this utility model are as follows:

[0023] This utility model is easy to operate, replacing manual operation with automatic operation to realize the automation of equipment cleaning and maintenance; the cleaning mechanism of this utility model adopts a crank-slider transmission structure for transmission, so that the brush performs reciprocating linear cleaning motion relative to the filter element, automatically removing dust, which can easily and timely clean the dust, avoid manual operation, improve maintainability, and at the same time improve the product quality level of meteorological observation equipment.

[0024] This utility model also has the following advantages:

[0025] This utility model adopts a design of drive motor plus transmission mechanism, and uses a compact crank-slider mechanical mechanism for transmission to drive the brush strip to perform reciprocating wiping dust operation.
