Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring instrument technology, specifically to an adjustment mechanism for an environmental monitoring instrument. Background Technology

[0002] Environmental monitoring instruments are used to monitor various parameters of indoor and outdoor environments. With social development, environmental monitoring is gradually moving towards automation, intelligence and networking. Various monitoring instruments are integrated and set up in exposed environments, and the monitoring data is collected through cables to achieve real-time monitoring of the environment. The support frame is a support device used to fix environmental protection monitoring instruments during installation.

[0003] Existing environmental monitoring instrument support frames are mostly simple column-shaped support rods, which cannot be flexibly adjusted during use, making installation and maintenance inconvenient. Generally, depending on the monitoring environment and the type of environmental monitoring instrument used, the height of the environmental monitoring instrument needs to be adjusted before monitoring begins to adapt to the monitoring requirements. Furthermore, as the monitoring cycle and monitoring targets change, the type of environmental monitoring instrument also needs to be changed. Therefore, when using existing support frames to install environmental monitoring instruments, external lifting equipment is required to raise the instrument to the predetermined height for replacement or maintenance, reducing maintenance convenience. Operators also need to use climbing tools, making operation more difficult. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide an adjustment mechanism for environmental monitoring instruments. This mechanism solves the problem that since each environmental monitoring instrument is integrated on the top of the support frame, it requires the assistance of external lifting equipment to raise the instruments to a certain height, and that staff need to use climbing tools to climb to the corresponding position to maintain the instruments.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustment mechanism for an environmental monitoring instrument, comprising a base, universal wheels installed at the four corners of the base bottom, a support frame at the top of the base, a lifting groove on the inner side of the support frame, a lifting motor at the bottom of the base, a lifting rod extending from the output end of the lifting motor into the lifting groove, the lifting rod being rotatably connected to the lifting groove, a lifting block threadedly connected to the lifting rod, the lifting block being slidably connected to the lifting groove, a support frame on the surface of the lifting block, a monitoring and control host at the top of the support frame, a monitoring instrument group at the top of the monitoring and control host, a locking cavity at the bottom of the lifting groove, a locking gear on the surface of the lifting rod, the locking gear being located inside the locking cavity, a sliding hole on the front of the support frame, a locking pin slidably connected inside the sliding hole, an arc-shaped semi-tooth block at the inner end of the locking pin, the semi-tooth block cooperating with the locking gear, a locking spring sleeved on the surface of the locking pin, the locking spring being located between the semi-tooth block and the locking cavity.

[0006] As a preferred embodiment of this utility model, the two sides of the semi-tooth block are symmetrically slidably connected with limit strips, and the limit strips are fixedly connected to the locking cavity. The inner wall of the limit strip is provided with a limiting groove, and the two sides of the semi-tooth block are symmetrically provided with limiting blocks, and the limiting blocks are slidably connected to the limiting grooves.

[0007] As a preferred embodiment of this utility model, the top of the semi-tooth block is provided with a fastening groove, the bottom of the lifting groove is provided with a fixing hole, the inner wall of the fixing hole is provided with a pressing groove, a fastening bolt is slidably connected inside the fixing hole, and the fastening bolt is used in conjunction with the fastening groove, the surface of the fastening bolt is provided with a pressing ring, and the pressing ring is slidably connected with the pressing groove, and a pressing spring is sleeved on the surface of the fastening bolt, and the pressing spring is located above the pressing ring.

[0008] As a preferred embodiment of the present invention, the interior of the lifting groove is provided with four mutually symmetrical sliding columns, and the surface of the lifting block is provided with four sliding openings, and the four sliding openings are respectively slidably connected to the four sliding columns.

[0009] As a preferred embodiment of this utility model, the top of the support frame is provided with a photovoltaic panel and a storage battery, and the two sides of the support frame are symmetrically provided with reflective strips.

[0010] As a preferred embodiment of this utility model, the top of the base is symmetrically threaded with a brake foot about the support frame, and the bottom of the brake foot is provided with a brake block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes casters at the bottom of the base to enable overall movement of the device, facilitating position adjustments for different monitoring scenarios. It is particularly useful in industrial parks where different locations have varying monitoring needs, allowing for direct relocation. A lifting motor drives the lifting rod to rotate, and a threaded lifting block moves the support frame, control unit, and monitoring instrument assembly up and down. The height is adjusted according to the specific requirements of the monitoring target. After adjustment, the locking gear and half-tooth block engage to ensure the lifting block reaches the target height. Then, a locking pin pushes the half-tooth block into the teeth of the locking gear, and a locking spring maintains the locked state, preventing the lifting rod from reversing due to external force and ensuring the overall structural stability after adjustment.

[0013] In addition, it facilitates the lowering of the control host and monitoring instrument group to the lowest point, thereby making it easier to perform maintenance work without requiring staff to climb to higher ground, and the corresponding maintenance operations can be carried out on the ground.

[0014] Meanwhile, through the sliding cooperation of the limiting strip, limiting groove and limiting block, the half-tooth block is restricted to linear movement, thereby ensuring that it can only slide horizontally, so as to engage or disengage with the locking gear, avoid the half-tooth block from tilting during the locking process, improve the stability and reliability of the locking mechanism, and enhance the guiding of the half-tooth block, prevent the locking pin from jamming due to uneven force, and ensure smooth locking and unlocking operations.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, this utility model provides an adjustment mechanism for an environmental monitoring instrument, mainly used in outdoor scenarios and relatively fixed locations for monitoring various environmental parameters, such as key monitoring locations in industrial parks. Because the monitoring location needs to be changed or the instrument replaced as the monitoring progresses, it needs to be easily movable and allow for relative height adjustment of the instrument's position to meet monitoring requirements. Specifically, it includes a base 1 with casters at each of the four corners. A support frame 2 is located at the top of the base 1, and a lifting groove 3 is formed on the inner side of the support frame 2. A lifting motor 4 is located at the bottom of the base 1, and a lifting rod 5 extends from the output end of the lifting motor 4 into the lifting groove 3. The lifting rod 5 is rotatably connected to the lifting groove 3. A retractable protective sleeve is fitted onto the surface of the lifting rod 5, extending and retracting with the lifting rod 5 to cover the threaded parts, providing a certain degree of shielding for the lifting mechanism and effectively preventing dust and moisture from entering and causing rotational jamming. Specifically, a lifting block 6 is threadedly connected to the lifting rod 5, and the lifting block 6 is slidably connected to the lifting groove 3. A support frame 7 is provided on the surface of the lifting block 6. The lifting block 6 slides stably within the lifting groove 3, and the relative position of the lifting block 6 is rotated by the threaded engagement between the lifting rod 5 and the lifting block 6. It can also achieve preliminary self-locking after adjustment to ensure that the position of the lifting block 6 will not change significantly. At the same time, a monitoring and control host 8 is provided on the top of the support frame 7, and a monitoring instrument group 9 is provided on the top of the monitoring and control host 8. The monitoring and control host 8 is used for signal processing and transmission, and a conventional PLC control box can be used. The monitoring instrument group 9 mainly consists of sensors such as PM2.5 sensors, wind speed sensors, temperature sensors, humidity sensors, and specific harmful gas monitors, which can be directly integrated using existing mature products.

[0022] To further prevent the lifting motor 4 from rotating the lifting rod 5 due to misoperation, a locking structure is needed to limit this and avoid potential risks. Specifically, a locking cavity 10 is provided at the bottom of the lifting groove 3, and a locking gear 11 is provided on the surface of the lifting rod 5, with the locking gear 11 located inside the locking cavity 10. A sliding hole is provided on the front of the support frame 2, and a locking pin 12 is slidably connected inside the sliding hole. The inner end of the locking pin 12 is provided with an arc-shaped semi-tooth block 13, which works in conjunction with the locking gear 11. A locking spring 14 is fitted on the surface of the locking pin 12, and the locking spring 14 is located between the semi-tooth block 13 and the locking cavity 10.

[0023] refer to Figure 4 The two sides of the half-tooth block 13 are symmetrically connected to the limiting strip 15, and the limiting strip 15 is fixedly connected to the locking cavity 10. The inner wall of the limiting strip 15 is provided with a limiting groove 16. The two sides of the half-tooth block 13 are symmetrically provided with limiting blocks 17, and the limiting blocks 17 are slidably connected to the limiting groove 16.

[0024] As a technical optimization of this utility model, the sliding cooperation of the limiting strip 15, the limiting groove 16 and the limiting block 17 restricts the half-tooth block 13 to only move linearly, thereby ensuring that it can only slide horizontally, so as to engage or disengage with the locking gear 11, avoid the half-tooth block 13 from tilting during the locking process, improve the stability and reliability of the locking mechanism, and at the same time enhance the guiding of the half-tooth block 13, prevent the locking pin 12 from jamming due to uneven force, and ensure smooth locking and unlocking operations.

[0025] refer to Figure 3 and Figure 4 The top of the half-tooth block 13 is provided with a fastening groove 18, the bottom of the lifting groove 3 is provided with a fixing hole 19, the inner wall of the fixing hole 19 is provided with a pressing groove, the inside of the fixing hole 19 is slidably connected with a fastening bolt 20, and the fastening bolt 20 is used in conjunction with the fastening groove 18. The surface of the fastening bolt 20 is provided with a pressing ring 21, and the pressing ring 21 is slidably connected with the pressing groove. The surface of the fastening bolt 20 is fitted with a pressing spring 22, and the pressing spring 22 is located above the pressing ring 21.

[0026] As a technical optimization of this utility model, by cooperating with the fastening bolt 20 and the fastening groove 18, when the half-tooth block 13 is locked, the fastening bolt 20 is inserted into the fastening groove 18, and the half-tooth block 13 is pressed by the elastic force of the downward pressure spring 22, thereby forming a double locking structure, further preventing the half-tooth block 13 from loosening due to vibration and other factors, and improving the safety of the device in the working state. Then, the downward pressure ring 21 and the downward pressure groove are used to limit the movement range of the fastening bolt 20, avoid excessive pressure and damage to the parts, and at the same time ensure that the spring force of the downward pressure spring 22 can be evenly transmitted.

[0027] refer to Figure 1 and Figure 2The lifting groove 3 has four mutually symmetrical sliding columns 23 inside, and the lifting block 6 has four sliding openings on its surface, and the four sliding openings are slidably connected to the four sliding columns 23 respectively.

[0028] As a technical optimization of this utility model, the sliding column 23 and the sliding opening of the lifting block 6 form a guiding structure, which enhances the stability of the lifting block 6 during the lifting process, prevents the lifting block 6 from tilting due to the radial force of the threaded transmission of the lifting rod 5, ensures the vertical lifting of the monitoring instrument group 9, and avoids data acquisition deviation.

[0029] refer to Figure 1 and Figure 2 The top of the support frame 2 is equipped with photovoltaic panels 24 and a battery. Reflective strips are symmetrically arranged on both sides of the support frame 2 to indicate the location. The photovoltaic panels 24, using mature technology, absorb solar energy and generate electricity, which is then stored in the battery to ensure the normal operation of the environmental monitoring instrument in the event of a short power outage. Specifically, the power supply for the lifting motor 4 can be either from the mains or through a generator transported by the operator on-site. Generally, once the relative position is adjusted, no further adjustments are needed; adjustments are only made when the monitoring target needs to be changed.

[0030] refer to Figure 1 The top of the base 1 is symmetrically threaded with a brake foot 25 about the support frame 2, and a brake block 26 is provided at the bottom of the brake foot 25.

[0031] As a technical optimization of this utility model, the brake foot 25 and the brake block 26 are connected to the base 1 by threads. Rotating the brake foot 25 can make the brake block 26 contact the ground. The position of the device is fixed by friction. It can switch between "moving-fixed" mode with the universal wheel. It is suitable for scenarios that require stable monitoring.

[0032] The working principle and usage process of this utility model are as follows: When using this adjustment mechanism, first confirm that the brake foot 25 is in the retracted state, that is, the brake block 26 is in the off-ground state. Move the device to the target monitoring position via the universal wheels. Then rotate the brake foot 25 to press the brake block 26 against the ground and fix the position of the device. Then connect the power supply or use the battery for power. When it is necessary to adjust the height of the monitoring instrument group 9, first pull the fastening bolt 20 upward so that its surface is away from the half tooth block 13, and drive the lower pressure ring 21 to squeeze the lower pressure spring 22. Then pull the locking pin 12 outward to the maximum position so that it slides outward within the limit strip 15. At this time, the half tooth block 13 disengages from the locking gear 11. Then release the fastening bolt 20. Use the reaction force of the lower pressure spring 22 to push the fastening bolt 20 to engage with the fastening groove 18 on the half tooth block 13, and enable the locking spring 14 to start the lifting motor 4. Observe the height change of the monitoring instrument group 9. The motor stops when the required monitoring height, such as the pollution source height or standard monitoring height, is reached. At this point, the lifting block 6 is stationary in the lifting groove 3. The sliding column 23 is used to keep its movement stable. Then, the fastening bolt 20 is pulled upward again so that its surface leaves the fastening groove 18. At this time, the reaction force of the locking spring 14 pushes the half-tooth block 13 to mesh with the locking gear 11, thereby limiting the rotation of the locking gear 11 and locking the rotation of the lifting rod 5. Then, the fastening bolt 20 is released so that it is engaged with the rear side of the half-tooth block 13 by the reaction force of the downward spring 22, thereby blocking the movement trajectory of the half-tooth block 13 and improving the positioning effect of the half-tooth block 13. This allows the height of the monitoring instrument group 9 to be positioned after adjustment. In addition, when the lifting block 6 is lowered to the lowest point, the staff can directly inspect and maintain the control host 8 and the monitoring instrument group 9, which is convenient for the staff to use.
