Description
Technical Field
[0001] This invention relates to the field of sensor technology, and in particular to a protective structure for a temperature and humidity sensor. Background Technology
[0002] A temperature and humidity sensor is a sensor capable of simultaneously measuring temperature and humidity, widely used in meteorology, agriculture, industry, and other fields. It can monitor environmental temperature and humidity in real time and synchronously, converting the detected data into electrical signals via electronic components, and finally displaying the data through a display element.
[0003] In the mining industry, temperature and humidity are crucial indicators in mining operations, making temperature and humidity sensors essential equipment. However, since particles frequently fall from the mine walls, and since temperature and humidity sensors are typically fixed to their housings, impacts can easily transmit equivalent vibrations, potentially causing damage. Therefore, a protective structure for temperature and humidity sensors is necessary. Summary of the Invention
[0004] The purpose of this invention is to solve the problems in the background art by proposing a protective structure for a temperature and humidity sensor.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a protective structure for a temperature and humidity sensor, comprising a U-shaped outer shell, a U-shaped first filter cotton inside the outer shell, two symmetrical mounting seats inside the first filter cotton, the outer shell, the first filter cotton and the mounting seats being fixedly mounted inside the outer shell by a first bolt, each mounting seat being provided with a buffer spring, and four buffer springs being provided on the same mounting seat, with the ends of the four buffer springs away from the mounting seats approaching each other, two connecting plates being provided between the two mounting seats, the ends of the buffer springs on the same side away from the mounting seats being fixedly connected to the connecting plates, and a sensor body being fixedly mounted between the two connecting plates;
[0006] Protective plates are provided on both sides of the outer shell, and several connecting seats are provided on the outer wall of the outer shell. The protective plates are fixedly installed on the connecting seats by the second bolts. Square frame-shaped slots are opened on both sides of the outer shell. A square frame-shaped retaining ring is fixedly installed on the side of the protective plate near the slot. The retaining ring is inserted into the slot. A second filter cotton is provided between the protective plate and the outer shell. The second filter cotton is engaged with the slot.
[0007] In the protective structure of the temperature and humidity sensor described above, several positioning blocks are fixedly installed on the inner wall of the outer shell. There are two sets of positioning blocks, and four positioning blocks in the same set. A support plate is provided inside the outer shell, and the support plate abuts against the positioning blocks.
[0008] In the protective structure of the temperature and humidity sensor described above, the positioning block has an arc-shaped notch, and the four corners of the support plate have through holes. Limiting rods are fixedly installed on the side of the two protective plates that are close to each other. There are four limiting rods on the same protective plate. The limiting rods on the same side pass through the through holes, and the limiting rods correspond one-to-one with the positioning blocks on the same side and abut against the notch.
[0009] In the protective structure of the temperature and humidity sensor described above, the outer shell is provided with a dust removal mechanism, which includes a dust removal fan and an outer cover. The dust removal fan is fixedly mounted on the outer shell, and the outer cover covers the outside of the dust removal fan. The bottom of the outer cover is fixedly mounted on the outer shell, and a dust blocking mechanism is provided inside the outer cover and located outside the dust removal fan.
[0010] In the protective structure of the temperature and humidity sensor described above, the dust blocking mechanism includes a first guide housing and a second guide housing. The first guide housing is fixedly installed on the inner wall of the outer cover, and the second guide housing is fixedly installed on the dust removal fan. An air inlet channel is provided between the first guide housing and the second guide housing, and a collection mechanism is provided on the outer cover.
[0011] In the protective structure of the temperature and humidity sensor described above, the collection mechanism includes a rotating ring, a brush, and an arc-shaped sliding cover. The rotating ring is rotatably connected to the outer ring wall of the second guide housing. The brush is evenly distributed on the outer ring wall of the rotating ring. The outer cover has a discharge port. The sliding cover is inserted into the outer cover. The arc-shaped surface of the sliding cover abuts against the second bolt. Two symmetrically arranged limiting blocks are fixedly installed on the outer wall of the sliding cover. The two limiting blocks abut against the two protective plates respectively.
[0012] In the protective structure of the temperature and humidity sensor described above, a partition plate is fixedly installed on the inner wall of the outer cover, and both sides of the partition plate are provided with an arc-shaped concave structure.
[0013] In the protective structure of the temperature and humidity sensor described above, two symmetrically arranged wind-driven plates are fixedly installed on the sensor body.
[0014] In the protective structure of the temperature and humidity sensor described above, the bottom of the outer shell is provided with several evenly distributed first air outlets, and the first filter cotton is provided with several second air outlets. The first air outlets and the second air outlets correspond one-to-one. An elastic element is fixedly installed on the inner wall of the first air outlet, and one end of the elastic element abuts against the inner wall of the first air outlet.
[0015] In the protective structure of the temperature and humidity sensor described above, several moisture-absorbing cotton strips are fixedly installed on the inner wall of the filter cotton.
[0016] Compared with existing technologies, the advantages of this invention are as follows: 1. This invention designs a housing, mounting base, connecting plate and two sets of buffer springs. When the housing is impacted, the arrangement of four buffer springs on the same side facilitates the reduction of vibration of the sensor body in the vertical and front-back directions. When the sensor body vibrates left and right, the two sets of buffer springs between the two mounting bases reduce the vibration amplitude of the sensor body, thus preventing the sensor body from being damaged by vibration due to fixed connection.
[0017] 2. This invention designs a dust removal mechanism and a dust blocking mechanism. The dust removal mechanism cleans the dust accumulated inside the outer casing, and the dust blocking mechanism prevents larger particles from entering the dust removal fan, thereby preventing the dust removal fan from getting stuck.
[0018] 3. This invention incorporates a fan-driven plate and an elastic element. Airflow is introduced into the housing by a dust removal fan, and the force exerted on the fan-driven plate causes the sensor body to vibrate, further enhancing the dust removal effect. When the dust removal fan is not working, the first air outlet is sealed by the elastic element. When the dust removal fan is working, the elastic element bends downward under the push of the airflow. At this time, dust is carried away from the housing by the airflow through the second air outlet and the first air outlet. Attached Figure Description

[0032] Reference Figures 1-10A protective structure for a temperature and humidity sensor includes a U-shaped outer shell 1. A U-shaped first filter cotton 2 is disposed inside the outer shell 1. Two symmetrical mounting seats 4 are disposed inside the first filter cotton 2. The outer shell 1, the first filter cotton 2, and the mounting seats 4 are fixedly mounted inside the outer shell 1 by a first bolt. Each mounting seat 4 is provided with a buffer spring 401, and four buffer springs 401 are provided on the same mounting seat 4. The ends of the four buffer springs 401 furthest from the mounting seat 4 are close to each other. Two connecting plates 402 are disposed between the two mounting seats 4. The ends of the buffer springs 401 on the same side furthest from the mounting seat 4 are connected to the connecting plate 402. 02. Fixed connection: A sensor body 5 is fixedly installed between two connecting plates 402. Protective plates 6 are provided on both sides of the outer casing 1. Several connecting seats 601 are provided on the outer wall of the outer casing 1. The protective plates 6 are fixedly installed on the connecting seats 601 by second bolts. Square-shaped slots 101 are provided on both sides of the outer casing 1. A square-shaped retaining ring 602 is fixedly installed on the side of the protective plate 6 near the slot 101, and the retaining ring 602 is inserted into the slot 101. A second filter cotton 7 is provided between the protective plate 6 and the outer casing 1, and the second filter cotton 7 engages with the slot 101. Several positioning blocks 8 are fixedly installed on the inner wall of the outer casing 1. Two sets of positioning blocks 8 are provided, with four positioning blocks 8 in each set. A support plate 9 is provided inside the outer shell 1, which abuts against the positioning blocks 8. The positioning blocks 8 have an arc-shaped notch 801. Through holes 901 are provided at each of the four corners of the support plate 9. Limiting rods 802 are fixedly installed on the side of the two protective plates 6 that are close to each other. There are four limiting rods 802 on the same protective plate 6. The limiting rods 802 on the same side pass through the through holes 901. The limiting rods 802 correspond one-to-one with the positioning blocks 8 on the same side and abut against the notches 801. The first filter cotton 2 is used to filter dust, and the positioning blocks 8 are used to position the first filter cotton 2. The buffer spring 401 serves to buffer vibration. When the outer shell 1 is impacted, the arrangement of the four buffer springs 401 on the same side helps to reduce the vibration of the sensor body 5 in the vertical and front-back directions. When the sensor body 5 vibrates left and right, the two sets of buffer springs 401 between the two mounting bases 4 reduce the vibration amplitude of the sensor body 5, preventing the sensor body 5 from being damaged by vibration due to the fixed connection. The second filter cotton 7 is used to further enhance the protection against dust. The retaining ring 602 is used to fix the second filter cotton 7 on the support hole plate 9. The limiting rod 802 is used to limit the first filter cotton 2 to prevent it from vibrating and dislodging.
[0033] The outer casing 1 is equipped with a dust removal mechanism 10, which includes a dust removal fan 11 and an outer cover 12. The dust removal fan 11 is fixedly mounted on the outer casing 1, and the outer cover 12 covers the outside of the dust removal fan 11. The bottom of the outer cover 12 is fixedly mounted on the outer casing 1. A dust blocking mechanism 13 is provided inside the outer cover 12 and outside the dust removal fan 11. The dust blocking mechanism 13 includes a first guide housing 14 and a second guide housing 15. The first guide housing 14 is fixedly mounted on the inner wall of the outer cover 12, and the second guide housing 15 is fixedly mounted on the dust removal fan 11. An air inlet channel 122 is provided between the first guide housing 14 and the second guide housing 15. A collection mechanism 16 is provided on the outer cover 12. The collection mechanism 16 includes... The rotating ring 17, brush 18, and arc-shaped sliding cover 19 are rotatably connected to the outer ring wall of the second guide housing 15. The brush 18 is evenly distributed on the outer ring wall of the rotating ring 17. The outer cover 12 has a discharge port 121. The sliding cover 19 is inserted into the outer cover 12. The arc-shaped surface of the sliding cover 19 abuts against the second bolt. Two symmetrically arranged limiting blocks 20 are fixedly installed on the outer wall of the sliding cover 19. The two limiting blocks 20 abut against the two protective plates 6 respectively. The dust removal fan 11 rotates, so that the air enters the interior from the outer cover 12 to remove dust from the sensor body 5. The dust blocking mechanism 13 filters out particulate impurities to a certain extent. The collection mechanism 16 stores the particulate impurities inside for easy removal.
[0034] A partition plate 21 is fixedly installed on the inner wall of the outer cover 12. Both sides of the partition plate 21 are provided with arc-shaped concave structures. The partition plate 21 is used to reduce blind spots in cleaning.
[0035] Two symmetrically arranged fan plates 22 are fixedly installed on the sensor body 5. When the dust removal fan 11 blows air into the sensor body 5, the fan plates 22 are subjected to force and drive the sensor body 5 to vibrate, causing the dust on the surface to fall off and improving the dust removal effect on the sensor body 5.
[0036] The bottom of the outer casing 1 has several evenly distributed first air outlets 23, and the first filter cotton 2 has several second air outlets 24. The first air outlets 23 and the second air outlets 24 correspond one-to-one. An elastic element 25 is fixedly installed on the inner wall of the first air outlet 23. One end of the elastic element 25 abuts against the inner wall of the first air outlet 23. The elastic element 25 is used to seal the first air outlet 23. When the dust removal fan 11 is working, the elastic element 25 is bent downward under the action of the airflow, so that the first air outlet 23 is connected to the outside. At this time, the dust inside is discharged through the first air outlet 23 and the second air outlet 24 under the drive of the airflow.
[0037] Several moisture-absorbing cotton strips 3 are fixedly installed on the inner wall of the filter cotton. The moisture-absorbing cotton strips 3 are used to prevent the inside of the outer shell 1 from being too damp, thus causing a mismatch with the external humidity.
[0038] The working principle and usage of this invention are explained in detail below: When the outer casing 1 is impacted and vibrates, the deformation of the buffer spring 401 reduces the vibration amplitude, thereby reducing the vibration amplitude of the sensor body 5. Simultaneously, when environmental vibration generates dust particles, the first filter cotton 2 and the second filter cotton 7 prevent most of the dust from entering the outer casing 1. When larger particles enter the outer cover 12 from the top, the airflow driven by the dust removal fan 11 causes them to fall along the top of the first guide member into the annular space between the first guide member and the outer cover 12. Under the action of the second guide and gravity, the particulate matter is kept inside the outer cover 12, while the airflow enters the outer shell 1 through the air inlet channel 122, removing the small amount of dust accumulated on the sensor body 5. When the dust removal fan 11 blows air into the interior, the fan plate 22 is forced to vibrate the sensor body 5, causing the dust on the surface to fall off, thus improving the dust removal effect on the sensor body 5. At the same time, under the action of the airflow, the elastic member 25 is bent downward, so that the first air outlet 23 is connected to the outside. At this time, under the action of the airflow, the dust inside is discharged through the first air outlet 23 and the second air outlet 24.
[0039] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.
[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
