Description

Technical Field

[0001] This utility model relates to the field of sensor verification technology, and in particular to a portable temperature and humidity sensor verification auxiliary device. Background Technology

[0002] To ensure the accuracy, reliability, and consistency of temperature and humidity sensor measurement data and to guarantee the quality of meteorological observations, it is necessary to conduct on-site verification of outdoor temperature and humidity sensors using temperature and humidity standards.

[0003] Currently, in order to reduce construction costs and due to limitations such as site size, most field automatic weather stations (hereinafter referred to as automatic stations) that undertake unmanned observation tasks are not equipped with Stevenson screens for temperature and humidity observation. Therefore, the temperature and humidity sensors are actually installed in a temperature and humidity radiation shield fixed at the bottom of the wind mast in the observation field, with the sensing center of both sensors 1.5 meters above the ground.

[0004] Due to assembly size limitations, the bottom of the radiation shield has no additional insertion holes besides the inward insertion holes for the temperature and humidity sensors. This means that when conducting on-site verification (metrological comparison and calibration) of the temperature and humidity sensors, the sensors currently in use at the automatic station must be removed from their radiation shields and placed together with the corresponding on-site verification standard probes, exposed outside the radiation shield. Without the relatively stable temperature and humidity measurement environment inside the radiation shield, the temperature and humidity sensors and standard probes are frequently affected by irregular airflow, improper operation, and thermal radiation from different directions, resulting in significant fluctuations in the measured comparison values.

[0005] The built-in sensing element of the standard probe has the physical characteristic of responding quickly to environmental changes, while the sensor's response speed is relatively slow. Therefore, the waiting time for the temperature and humidity sensors and the standard to simultaneously measure the on-site temperature and humidity environmental values ​​to reach a relatively stable level that meets the comparison requirements is relatively long, which seriously affects the efficiency of on-site verification work. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of the aforementioned technologies and provide a portable temperature and humidity sensor verification auxiliary device.

[0007] Therefore, this utility model provides a portable temperature and humidity sensor verification auxiliary device, including a support plate and a multi-chamber ventilation box. A positioning plate is fixedly installed on the top of the ventilation box. The positioning plate has multiple positioning holes for placing sensors and standards. The support plate and the ventilation box are connected by a rope, and an adjustment component for adjusting the distance between the two is installed on the rope.

[0008] Preferably, the ventilation box includes a connecting rod and a disc, the disc having an inverted butterfly shape, and multiple discs are stacked on top of each other via the connecting rod, with a gap between adjacent discs.

[0009] Preferably, the disk includes an upper disk, a lower disk, and a middle disk. The upper disk and the lower disk are respectively disposed at the top and bottom of the middle disk. The upper disk has a circular hole corresponding to the positioning hole. The lower disk has a hole-free structure. The middle disk has a cavity one and a cavity two. The cavity two is arranged in a ring array around the cavity one. The sensor and the standard are inserted into the cavity one.

[0010] Preferably, the first cavity is a circular structure, and the second cavity is an elliptical structure or a circular arc groove structure.

[0011] Preferably, the adjusting component includes a clamping plate, a pressure plate, a bolt, and a nut. The rope and its end passing through the support plate are both located in the groove of the clamping plate. The pressure plate presses against the rope. The bolt passes through the clamping plate and the pressure plate in sequence and is fixed by the nut.

[0012] Preferably, the groove is an arc-shaped or trapezoidal structure.

[0013] Preferably, the top of the connecting rod passes through the positioning plate and is fixedly installed with a lifting ring, and the bottom of the rope is fixedly installed with a spring hook, which is connected to the lifting ring.

[0014] Preferably, the top of the support plate has a hole.

[0015] The beneficial effects of this utility model are as follows: This utility model provides a portable temperature and humidity sensor verification auxiliary device, which has the following beneficial effects.

[0016] (1) Place the support plate on the top of the radiation shield and hang the ventilation box below. With the help of the adjustment components, make the vertical length of the ropes distributed on the support plate consistent to meet the verticality requirements of the ventilation box. At the same time, reserve the installation space for the sensor and the standard. First, install the standard, and then take the sensor out of the radiation shield and quickly install it to start the on-site verification work. This shortens the waiting time, makes the verification results more accurate and reliable, greatly improves work efficiency, and ensures the quality of meteorological observation.

[0017] (2) The ventilation box forms a multi-cavity structure by stacking multiple butterfly-shaped discs, which can eliminate the effects of solar heat radiation and rain in all directions; the reasonable gap between the discs ensures smooth and timely airflow exchange between the inside and outside of the ventilation box, ensuring that the sensors and standards installed in the box can detect changes in the detection environment in real time and quickly.

[0018] (3) The support plate and rope hanging structure enable the device to be installed quickly and easily at the verification site, saving a lot of installation and adjustment time and improving installation efficiency;

[0019] (4) This device is characterized by its small size, light weight, easy cleaning, robust structure, and portability, which reduces the workload and difficulty for front-line verification personnel. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products. Example

[0032] like Figures 1 to 8 As shown, this utility model provides a portable temperature and humidity sensor verification auxiliary device, including a support plate 1 and a multi-cavity ventilation box 2. The support plate 1 has a triangular structure, which ensures support stability and is also easy to handle.

[0033] A positioning plate 3 is fixedly installed on the top of the ventilation box 2. A mounting bracket is fixedly installed on the positioning plate 3 for installing sensors and standards. The positioning plate 3 has multiple positioning holes 4 for placing sensors and standards. In this embodiment, the positioning holes 4 include a first positioning hole 41, a second positioning hole 42, a third positioning hole 43, and a fourth positioning hole 44. The first positioning hole 41 is used to insert a temperature sensor, the second positioning hole 42 is used to insert a humidity sensor, the third positioning hole 43 is used to insert a humidity standard, and the fourth positioning hole 44 is used to insert a temperature standard. The connecting lines of the temperature sensor and the temperature standard are arranged in a cross pattern with the humidity sensor and the humidity standard to reduce signal interference and optimize the spatial layout.

[0034] The support plate 1 and the ventilation box 2 are connected by a rope 5, and an adjustment component 6 for adjusting the distance between the two is installed on the rope 5.

[0035] Furthermore, the ventilation box 2 includes a connecting rod 21 and a disc 22. The disc 22 has an inverted and hollow butterfly-shaped structure. Multiple discs 22 are stacked on top of each other through the connecting rod 21. A gap is left between two adjacent discs 22 to ensure smooth and timely airflow exchange between the inside and outside of the ventilation box 2, so as to ensure that the sensors and standards installed in the box can detect changes in the detection environment in real time and quickly.

[0036] Furthermore, the disk 22 includes an upper disk 221, a lower disk 222, and a middle disk 223, with multiple middle disks 223. The upper disk 221 and the lower disk 222 are respectively disposed at the top and bottom of the middle disk 223. The upper disk 221 has a circular hole 7 corresponding to the positioning hole 4. The lower disk 222 has a hole-free structure. The middle disk 223 has a cavity 1 8 and a cavity 2 9. The cavity 2 9 is arranged in a ring array around the cavity 1 8. The sensor and the standard are inserted into the cavity 1 8.

[0037] Furthermore, cavity 8 is a circular structure, and cavity 9 is an elliptical structure or a circular arc groove structure. Compared with circular or square structures, the elliptical or circular arc groove structure of cavity 9 can form a more complex airflow path, which helps the air to be distributed more evenly in the ventilation box 2, thereby ensuring that the ambient temperature and humidity conditions of the sensor and the standard are more consistent, and improving the accuracy of on-site verification.

[0038] Furthermore, the adjusting component 6 includes a clamping plate 61, a pressure plate 62, a bolt 63, and a nut 64. The rope 5 and its end passing through the support plate 1 are both located within the groove 10 of the clamping plate 61. The pressure plate 62 presses against the rope 5. The bolt 63 passes through the clamping plate 61 and the pressure plate 62 in sequence and is fixed by the nut 64. The rope 5 passes around both sides of the bolt 63. The bolt 63 can provide a good guide for the movement path of the rope 5, preventing the rope 5 on both sides of the bolt 63 from crossing and getting tangled, thus affecting the normal adjustment of the rope 5.

[0039] Furthermore, the groove 10 has an arc-shaped or trapezoidal structure. In this embodiment, the groove 10 has a trapezoidal structure, which not only allows the rope 5 to pass through smoothly, but also facilitates the installation of the bolt 63 and enhances the firmness of the rope 5's position.

[0040] Furthermore, a connecting block 14 is fixedly installed at the end of the rope. The connecting block 14 prevents the end of the rope from detaching from or entering the clamping plate 61, making adjustment difficult.

[0041] Furthermore, the top of the connecting rod 21 passes through the positioning plate 3 and is fixedly installed with a lifting ring 11, and the bottom of the rope 5 is fixedly installed with a spring hook 12, which is connected to the lifting ring 11.

[0042] Furthermore, a hole 13 is provided at the top center of the support plate 1 to facilitate removal and installation.

[0043] The working principle is as follows:

[0044] The inspectors pass through the holes 13 on the support plate 1 and place the support plate 1 on the top surface of the radiation shield of the temperature and humidity sensor. The ropes 5 are evenly distributed around the temperature and humidity radiation shield. The ventilation box 2 is hung on the lower part of the lower edge of the temperature and humidity radiation shield. The length of the rope 5 is adjusted by pulling the end of the rope. After the adjustment is completed, the nut 64 on the bolt 63 is turned to make the pressure plate 62 press the rope 5 to fix it. The rope 5 meets the requirements of the length of the ropes 5 spanning around the radiation shield and the verticality of the ventilation box 2, and the installation space of the sensor and standard probe is reserved.

[0045] Install the temperature and humidity standard probes on the mounting bracket and insert them into positioning hole 4 and cavity 8, then allow them to acclimatize to the environment. After approximately 5-15 minutes (the duration is set according to the temperature difference between the device and the automatic station site), remove the temperature and humidity sensors to be verified from the radiation shield and quickly place them into ventilation box 2. Begin the on-site verification of the temperature and humidity sensors according to the verification procedure.

[0046] Because the standard's sensing element responds quickly to environmental changes, the standard is first placed in cavity 8. After a certain period of time, when the temperature and humidity of cavity 8 become the same as the outside environment, the standard can quickly sense the environmental change. Then, the sensor is quickly removed from the radiation shield and placed in cavity 8. Because the sensor's sensing speed is relatively slow, the sensor will retain the values ​​inside the radiation shield for a short period of time, making it convenient to use the standard to verify the sensor. Example

[0047] like Figures 9-10 As shown, based on Embodiment 1, this utility model provides a portable temperature and humidity sensor verification auxiliary device. The connecting rod 21 includes a first connecting rod 211 and a second connecting rod 212. The first connecting rod 211 and the second connecting rod 212 are detachably connected for easy storage and to reduce space occupation. The first connecting rod 211 is used to fix multiple discs 22 and passes through the top of the discs 22. The second connecting rod 212 and the first connecting rod 211 are fixedly connected by a fixing component. A hanging ring 11 is fixedly installed on the top of the second connecting rod 212.

[0048] Furthermore, the fixing component includes a nut 15, a protrusion 16, and a protrusion 17. The top of the connecting rod 211 is fixedly mounted with the protrusion 16, and the bottom of the connecting rod 212 is fixedly mounted with the protrusion 17. The protrusion 16 and the protrusion 17 are joined together, and the diameter of the joined parts is the same as the diameter of the connecting rod 21. The threads on the connecting rod 211, the protrusion 16, the connecting rod 212, and the protrusion 17 are continuous. The protrusion 16 and the protrusion 17 are fixedly connected by the nut 15.
