Description

Technical Field

[0001] This utility model belongs to the technical field of gas monitoring equipment, specifically relating to an air humidity monitoring instrument for environmental monitoring. Background Technology

[0002] An air humidity monitoring instrument is an instrument that can measure the water vapor content in the air. It is commonly used in warehouses, cold chain logistics, archives, museums, laboratories and other places with strict requirements for temperature and humidity environment to conduct long-term temperature and humidity monitoring and data recording to ensure that the storage environment conditions of the items meet the requirements.

[0003] In the aforementioned indoor spaces, humidity levels can vary in certain areas due to differences in ventilation or shelf placement. Taller and densely packed objects can obstruct vertical airflow, causing moisture to accumulate near these obstacles and resulting in a difference in humidity between the local area and the surrounding environment. This can create a difference in humidity levels at the top and bottom.

[0004] Existing air humidity monitoring instruments are usually installed in fixed positions, which makes it impossible to sample and monitor the air at different heights. As a result, the final data obtained cannot reflect the overall air humidity situation. For paper archives and cultural relics with high humidity requirements, the inability to obtain accurate humidity data for each area can lead to misjudgments of the actual situation by the custodians, resulting in unnecessary economic losses. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an air humidity monitoring instrument for environmental monitoring.

[0006] The technical solution adopted to solve the above technical problems is: to provide an air humidity monitoring instrument for environmental monitoring, including a support plate, the top wall of the support plate having symmetrically arranged limiting grooves, a moving mechanism being rolledly connected in the limiting grooves, a lifting mechanism being provided at the top of the moving mechanism, the bottom end of the lifting mechanism being fixedly connected to the moving mechanism, a monitoring instrument body being fixedly connected at the top of the lifting mechanism, a limiting mechanism being provided on one side of the lifting mechanism, and the bottom end of the limiting mechanism being movably connected to the lifting mechanism.

[0007] The above technical solution uses a lifting mechanism to raise and lower the monitoring instrument body, thereby enabling humidity monitoring of air at different heights. The movement of the moving mechanism along the limiting groove allows for the overall displacement of the equipment, thus ensuring the monitoring coverage of different areas by the monitoring instrument body.

[0008] Furthermore, a limiting ring is fixedly connected to the side wall of the support plate, and the limiting rings are arranged sequentially along the axial direction of the support plate.

[0009] The above technical solution allows fasteners to be used to pass through the limiting ring and fix the support plate to the ground, so that the support plate can provide stable support for the other equipment on top.

[0010] Furthermore, the lifting mechanism includes a column, a first drive shaft is provided on one side of the column, the first drive shaft passes through the side wall of the column and is fixedly connected to a first gear, the first drive shaft is rotatably connected to the column, a second drive shaft is provided parallel to one side of the first drive shaft, one end of the second drive shaft is rotatably connected to the side wall of the column, a second gear is fixedly connected to the outer wall of the second drive shaft, the second gear meshes with the first gear, a third gear is provided parallel to one side of the second gear, the third gear is fixedly connected to the outer wall of the second drive shaft, a rack is provided on one side of the third gear, the rack meshes with the third gear, limit plates are slidably connected to both sides of the rack, the limit plates are "L" shaped, the limit plates are fixedly connected to the side wall of the column, and the top of the rack is fixedly connected to the monitoring instrument body.

[0011] With the above technical solution, when the first drive shaft rotates, the first gear starts to drive the second gear to rotate. At this time, the third gear starts to rotate synchronously with the second gear. Through the meshing transmission between the third gear and the rack, the rack starts to move linearly along the limiting plate. The rack rises and falls by the forward and reverse rotation of the third gear.

[0012] Furthermore, a first blocking plate is fixedly connected to the top of the column sidewall, and a second blocking plate is fixedly connected to the bottom of the rack sidewall.

[0013] With the above technical solution, the rack will not go beyond the column and separate from the column when it moves upward due to the limiting effect of the first and second blocking plates.

[0014] Furthermore, a handle is fixedly connected to the end of the first drive shaft away from the first gear, and a ratchet is fixedly connected to the outer wall of the first drive shaft.

[0015] The above technical solution enables the first drive shaft to rotate by turning the handle.

[0016] Furthermore, the limiting mechanism includes a limiting block, the inclined surface of which is in contact with the outer wall of the ratchet, a support ring is fixedly connected to the top of the limiting block, a lifting rod is fixedly connected to the top wall of the support ring, a support block is slidably connected to the outer wall of the lifting rod, the side wall of the support block is fixedly connected to the column, and a spring is sleeved on the outer wall of the lifting rod, the spring being located between the bottom wall of the support block and the top wall of the support ring.

[0017] With the above technical solution, when the handle drives the first drive shaft to rotate clockwise, the first drive shaft drives the ratchet to rotate synchronously. The limiting block fits against the outer wall of the ratchet through its inclined surface. Under the pressure of the ratchet, it generates an upward displacement and compresses the spring through the support ring. When the handle stops rotating, under the action of the spring's elastic force, the support ring drives the limiting block to move downward. At this time, the limiting block and the ratchet teeth form a locking connection. Through the limiting action of the vertical surface of the limiting block, the first drive shaft remains stable, thereby achieving the limiting of the rack.

[0018] Furthermore, the moving mechanism includes a connecting plate, the top wall of which is fixedly connected to the column, and a first rotating rod and a second rotating rod rotatably connected to both ends of the bottom wall of the connecting plate, respectively. A first limiting wheel and a second limiting wheel are fixedly connected to both ends of the first rotating rod and the second rotating rod, respectively. The first limiting wheel and the second limiting wheel are in rolling connection with the limiting groove. A driven gear is fixedly connected to the outer wall of the first rotating rod, and a motor is provided on one side of the driven gear. A drive gear is fixedly connected to the output end of the motor, and the drive gear meshes with the driven gear. The motor is fixedly connected to the bottom wall of the connecting plate.

[0019] With the above technical solution, when the motor starts, the drive gear fixed at the output end of the motor drives the driven gear fixed on the outer wall of the first rotating rod to rotate, thereby realizing the rotation of the first limit wheel fixed at both ends of the first rotating rod. Through the displacement of the first limit wheel and the second limit wheel along the limit groove, the movement of the moving mechanism is realized, thereby realizing the movement of the entire equipment.

[0020] The beneficial effects of this utility model are as follows:

[0021] This invention utilizes a lifting mechanism to raise and lower the monitoring instrument body, enabling humidity monitoring of air at different heights. Rotating the handle drives the first transmission shaft, which in turn drives the first and second gears. Simultaneously, the third gear meshes with a rack, causing the rack to move linearly up and down along a limiting plate. The forward and reverse rotation of the third gear controls the rack's ascent and descent, thus enabling sampling and monitoring of air at different altitudes. This provides more comprehensive and specific feedback data and helps storage personnel develop more targeted and effective storage plans. A drive gear fixed at the motor output drives a driven gear fixed to the outer wall of the first rotating rod, rotating the first limiting wheels fixed at both ends of the first rotating rod. The displacement of the first and second limiting wheels along the limiting grooves moves the moving mechanism, thereby moving the monitoring instrument body to achieve comprehensive monitoring coverage of different areas.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] like Figure 1 - Figure 5 As shown, an air humidity monitoring instrument for environmental monitoring includes a support plate 1. The top wall of the support plate 1 has symmetrically arranged limiting grooves 2. A moving mechanism 4 is rotatably connected in the limiting grooves 2. A lifting mechanism 3 is provided at the top of the moving mechanism 4. The bottom end of the lifting mechanism 3 is fixedly connected to the moving mechanism 4. The top end of the lifting mechanism 3 is fixedly connected to the monitoring instrument body 7. A limiting mechanism 5 is provided on one side of the lifting mechanism 3. The bottom end of the limiting mechanism 5 is movably connected to the lifting mechanism 3.

[0030] A limiting ring 6 is fixedly connected to the side wall of the support plate 1. The limiting rings 6 are arranged sequentially along the axial direction of the support plate 1. Fasteners are used to pass through the limiting rings 6 to fix the support plate 1 to the ground.

[0031] The lifting mechanism 3 includes a column 301. A first drive shaft 303 is provided on one side of the column 301. The first drive shaft 303 passes through the side wall of the column 301 and is fixedly connected to a first gear 312. The first drive shaft 303 is rotatably connected to the column 301. A second drive shaft 302 is arranged parallel to one side of the first drive shaft 303. One end of the second drive shaft 302 is rotatably connected to the side wall of the column 301. A second gear 311 is fixedly connected to the outer wall of the second drive shaft 302. The second gear 311 is connected to... The first gear 312 is engaged, and the third gear 304 is arranged parallel to one side of the second gear 311. The third gear 304 is fixedly connected to the outer wall of the second transmission shaft 302. A rack 305 is arranged on one side of the third gear 304 and meshes with the third gear 304. Limiting plates 306 are slidably connected to both sides of the rack 305. The limiting plates 306 are "L" shaped and are fixedly connected to the side wall of the column 301. The top of the rack 305 is fixedly connected to the main body 7 of the monitoring instrument.

[0032] When the first drive shaft 303 rotates, the first gear 312 starts to drive the second gear 311 to rotate. At this time, the third gear 304 starts to rotate synchronously with the second gear 311. Through the meshing transmission between the third gear 304 and the rack 305, the rack 305 starts to move linearly along the limiting plate 306. The upward and downward movement of the rack 305 is realized by the forward and reverse rotation of the third gear 304.

[0033] A first blocking plate 307 is fixedly connected to the top of the side wall of the column 301, and a second blocking plate 308 is fixedly connected to the bottom of the side wall of the rack 305. Through the limiting effect of the first blocking plate 307 and the second blocking plate 308, the rack 305 will not go beyond the column 301 and separate from the column 301 when it moves upward.

[0034] A handle 309 is fixedly connected to the end of the first drive shaft 303 away from the first gear 312. A ratchet 310 is fixedly connected to the outer wall of the first drive shaft 303. The first drive shaft 303 is driven to rotate by rotating the handle 309.

[0035] The limiting mechanism 5 includes a limiting block 505, the inclined surface of which is in contact with the outer wall of the ratchet 310. A support ring 504 is fixedly connected to the top of the limiting block 505. A lifting rod 502 is fixedly connected to the top wall of the support ring 504. A support block 501 is slidably connected to the outer wall of the lifting rod 502. The side wall of the support block 501 is fixedly connected to the column 301. A spring 503 is sleeved on the outer wall of the lifting rod 502. The spring 503 is located between the bottom wall of the support block 501 and the top wall of the support ring 504.

[0036] When the handle 309 drives the first drive shaft 303 to rotate clockwise, the first drive shaft 303 drives the ratchet 310 to rotate synchronously. The limiting block 505 fits against the outer wall of the ratchet 310 through its inclined surface. Under the pressure of the ratchet 310, it generates an upward displacement and compresses the spring 503 through the support ring 504. When the handle 309 stops rotating, under the elastic force of the spring 503, the support ring 504 drives the limiting block 505 to move downward. At this time, the limiting block 505 and the ratchet 310 form a locking connection through the tooth gap. Through the limiting effect of the vertical surface of the limiting block 505, the first drive shaft 303 remains stable, thereby realizing the limiting of the rack 305.

[0037] The moving mechanism 4 includes a connecting plate 401. The top wall of the connecting plate 401 is fixedly connected to the column 301. A first rotating rod 402 and a second rotating rod 403 are rotatably connected to both ends of the bottom wall of the connecting plate 401. A first limiting wheel 404 and a second limiting wheel 405 are fixedly connected to both ends of the first rotating rod 402 and the second rotating rod 403, respectively. The first limiting wheel 404 and the second limiting wheel 405 are in rolling connection with the limiting groove 2. A driven gear 406 is fixedly connected to the outer wall of the first rotating rod 402. A motor 408 is provided on one side of the driven gear 406. A drive gear 407 is fixedly connected to the output end of the motor 408. The drive gear 407 meshes with the driven gear 406. The motor 408 is fixedly connected to the bottom wall of the connecting plate 401.

[0038] When the motor 408 starts, the drive gear 407 fixed at the output end of the motor 408 drives the driven gear 406 fixed on the outer wall of the first rotating rod 402 to rotate, thereby realizing the rotation of the first limiting wheel 404 fixed at both ends of the first rotating rod 402. Through the displacement of the first limiting wheel 404 and the second limiting wheel 405 along the limiting groove 2, the moving mechanism 4 is moved, thereby realizing the movement of the entire equipment.

[0039] In use, the support plate 1 is first placed in the area to be tested. Then, the handle 309 is rotated, causing the first transmission shaft 303 to rotate. When the first transmission shaft 303 rotates, the first gear 312 drives the second gear 311 to rotate. Simultaneously, the third gear 304 rotates synchronously with the second gear 311. Through the meshing of the third gear 304 and the rack 305, the rack 305 begins to move linearly along the limiting plate 306. When the rack 305 raises the monitoring instrument body 7 to a suitable position, the handle 309 stops rotating. At this point, under the elastic force of the spring 503, the support ring 504 drives the limiting block. 505 moves downward, and the limiting block 505 engages with the ratchet 310 through the tooth gap. The first transmission shaft 303 remains stable due to the limiting effect of the vertical surface of the limiting block 505, thereby limiting the rack 305. At this time, the motor 408 is started, and the driven gear 406 fixed on the outer wall of the first rotating rod 402 rotates through the drive gear 407 fixed at the output end of the motor 408. This causes the first limiting wheel 404 fixed at both ends of the first rotating rod 402 to rotate. Through the displacement of the first limiting wheel 404 and the second limiting wheel 405 along the limiting groove 2, the moving mechanism 4 moves, thereby moving the monitoring instrument body 7.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
