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

[0003] In the prior art, the support frames used for installing and fixing environmental protection monitoring instruments are mostly support columns with a single structure. A mounting hole is preset on the ground, and the bottom end of the support column is inserted into the mounting hole so that the support column stands vertically on the ground. The environmental protection monitoring instrument is then locked and fixed to the top of the support column with a clamp or other equipment, so that the environmental protection monitoring instrument can monitor the surrounding environment in real time.

[0004] However, most environmental protection monitoring instruments are fixedly installed on the upper part of the support column. It is difficult to ensure that the center of gravity is in the same straight line as the support axis of the support column during installation, and the center of gravity of the overall structure is upward. After the lower end of the support column is inserted into the mounting hole and fixed, the support column will apply downward pressure on one side of the opening of the mounting hole, and the lower end of the support column will apply an upward lifting force to the other side of the bottom of the mounting hole. Under long-term squeezing, there is a risk of the opening of the mounting hole expanding, which increases the risk of the support column tipping over. Utility Model Content

[0035] See also Figure 1-6 The utility model provides a technical solution: an environmental protection monitoring instrument carrier, wherein a ball head 111 is formed by protruding outward from the middle of the support column 11, and a connecting ring 12 is arranged on the outer cover of the ball head 111, and an auxiliary supporting part for lifting the support column 11 is connected to the connecting ring 12, and the bottom end of the support column 11 is suspended under the lifting action of the auxiliary supporting part;

[0036] A counterweight is provided between the bottom end of the support column 11 and the connecting ring 12 , and the counterweight is rotatably mounted on the side of the support column 11 and can rotate around the axis of the support column 11 .

[0037] When installing the support frame, the environmental protection monitoring instrument 3 is fixed and locked to the support column 11 with a clamp or other equipment in advance, and a mounting hole is dug in the ground. After the bottom end of the support column 11 is inserted into the mounting hole, there is a gap between the outer wall of the support column 11 and the side wall of the mounting hole, so that the support column 11 can shake and swing in the mounting hole. The auxiliary support part includes a plurality of support legs 16, and the plurality of support legs 16 are arranged in a circular array with the axis of the connecting ring 12 as the center line. One end of the support leg 16 is hinged to the outer wall of the connecting ring 12. By rotating the support leg 16 on the connecting ring 12, the angles and positions of the plurality of support legs 16 can be adjusted to facilitate the plurality of support legs 16 to adapt to uneven ground. The ends of the plurality of support legs 16 facing away from the connecting ring 12 are fixed to the ground by expansion bolts or cement pouring, so that the support column 11 is lifted and lifted, and the support column 11 is naturally suspended.

[0038] The ball head 111 is rotatably connected to the connecting ring 12, wherein the connecting ring 12 is equivalent to a ball head seat and the ball head 111 constitute a ball joint structure, so that the support column 11 can shake freely on the connecting ring 12. The connecting ring 12 and the support column 11 constitute a lever structure, the connecting ring 12 serves as the rotation fulcrum of the support column 11, the section of the support column 11 located above the connecting ring 12 is a power arm, and the section of the support column 11 located below the connecting ring 12 is a resistance arm.

[0039] After the environmental protection monitoring instrument 3 is installed, the center of gravity of the upper end of the support column will be offset, causing the support column 11 to rotate with the connecting ring 12 as the fulcrum. At this time, the position of the counterweight installed on the support column 11 can be adjusted. The adjustment method is: rotate the counterweight around the support column 11 to balance the pressure applied to the support column 11 by the environmental protection monitoring instrument 3 perpendicular to the support column 11, and adjust the vertical line of the center of gravity of the counterweight to be parallel to the vertical line of the center of gravity of the environmental protection monitoring instrument 3 and the axis of the support column 11. In this state, the support column 11 is in a vertical state on the connecting ring 12.

[0040] Then, cement mortar is injected into the installation hole to fill the gaps around and below the bottom of the support column 11, and then the support column 11 is erected on the ground. By installing the support column 11 on the ground in a vertical state, the horizontal pressure of the environmental protection monitoring instrument 3 on the support rod is weakened or even offset by the horizontal pressure of the counterweight block 22, so as to reduce or eliminate the pressure of the support column 11 on the side wall of the installation hole, reduce the risk of the installation hole opening expanding, and thus reduce the risk of the support column 11 tipping over.

[0041] In this embodiment: the counterweight portion includes a sleeve 21 coaxially rotatably matched with the support column 11, and a counterweight block 22 is connected to the outer wall of the sleeve 21;

[0042] The sleeve 21 is provided with a locking portion for limiting the sleeve 21 from rotating on the support column 11 .

[0043] By connecting the counterweight 22 to the outer wall of the sleeve 21, the center of gravity of the counterweight 22 is moved away from the axis of the support column 11. As the sleeve 21 rotates on the support column 11, the direction of the pressure applied by the counterweight 22 on the support column 11 that is perpendicular to the support column 11 changes accordingly. When the counterweight 22 rotates to the side of the support column 11 that is away from the environmental protection monitoring instrument 3, the direction of the pressure applied by the counterweight 22 on the support column 11 that is perpendicular to the support column 11 is opposite to the direction of the pressure applied by the environmental protection monitoring instrument 3 on the support column 11, thereby weakening or offsetting each other, so that the support column 11 is in a vertical state, thereby reducing the risk of the support frame tipping over.

[0044] In this embodiment: a threaded hole 211 penetrating the side wall of the sleeve 21 is opened on the side wall of the sleeve 21, and the locking portion includes a fastening bolt 23, the threaded end of the fastening bolt 23 is inserted into the threaded hole 211 and connected by threaded fitting, and the threaded end of the fastening bolt 23 is against the outer cylindrical surface of the support column 11.

[0045] A friction plate is fixedly connected to the end surface of the threaded end of the fastening bolt 23, and the friction plate abuts against the outer circumferential surface of the support column 11. The friction force between the friction plate and the outer circumferential surface of the support column 11 limits the relative rotation between the sleeve 21 and the support column 11.

[0046] In this embodiment: a sliding groove 212 is provided on the outer wall of the sleeve 21 along the axial direction of the sleeve 21, and one end of the counterweight block 22 is inserted into the sliding groove 212 and slides in cooperation;

[0047] A screw rod parallel to the sleeve 21 is provided in the slide groove 212, the bottom end of the screw rod is inserted into the bottom wall of the slide groove 212 and rotated, the top end passes through the counterweight block 22 and the top wall of the slide groove 212 in turn and extends out of the slide groove 212, and the screw rod is connected to the counterweight block 22 by threaded cooperation.

[0048] By setting a slide groove 212 and sliding the counterweight block 22 and the slide groove 212 along the axial direction of the shaft sleeve, the distance between the counterweight block 22 and the connecting ring 12 can be changed. Since the support column 11 and the mounting ring form a lever structure, the environmental protection monitoring instrument 3 serves as the force application point on the power arm, and the counterweight block 22 serves as the force application point on the resistance arm. The force application point and gravity of the environmental protection monitoring instrument 3 on the support column 11 remain unchanged, and the gravity of the counterweight block 22 also remains unchanged. Therefore, it is only necessary to drive the counterweight block 22 to slide on the slide groove 212 to change the position of the force application point on the resistance arm until the lever force is balanced and the support column 11 is in a vertical state.

[0049] During use, when the support column 11 needs to be adjusted to a vertical state, the relevant technician gently holds the support column 11 with one hand and unscrews the fastening bolt 23 with the other hand, visually observes the tilting direction of the support column 11, and rotates the sleeve 21 so that the counterweight 22 is located on the side of the support column 11 facing away from the environmental protection monitoring instrument 3, and then tightens the fastening bolt 23 to limit the rotation of the sleeve 21 on the support column 11; observe whether the support column 11 rotates, if the support column 11 does not rotate, rotate the screw rod forward, the screw rod pushes the counterweight 22 to slide downward in the slide groove 212, and increases the distance from the force application point on the resistance arm to the fulcrum until the support column 11 rotates to a vertical state; if the support column 11 rotates but tilts to the side of the counterweight 22, rotate the screw rod in the reverse direction, the screw rod drives the counterweight 22 to slide upward in the slide groove 212, shortening the distance from the force application point on the resistance arm to the fulcrum until the support column 11 rotates to a numerical state.

[0050] In this embodiment: a level 24 is fixedly connected to the top surface of the counterweight block 22, and when the level 24 is in a horizontal state, the support column 11 is in a vertical state.

[0051] The level 24 is a bubble level 24 , which is arranged on the top surface of the counterweight 22 . The inclination of the support column 11 can be intuitively obtained by observing the position of the bubble on the bubble level 24 , which facilitates the adjustment of the support column 11 .

[0052] In this embodiment, the support column 11 is a hollow structure with an opening at the bottom. A movable column 13 is provided at the bottom of the support column 11. One end of the movable column 13 is inserted into the support column 11 and slidably fits.

[0053] By setting a movable column 13, and inserting the movable column 13 into the support column 11 and slidingly connecting it, when adjusting the inclination angle of the support column 11, the movable column 13 is retracted into the support column 11 so that the bottom end of the support column 11 is suspended away from the ground, so that the support column 11 can rotate freely on the connecting ring 12, thereby providing convenience for the adjustment of the support column 11.

[0054] In this embodiment: a rotating sleeve 14 is provided on the outer sleeve of the bottom end of the support column 11, the top end of the rotating sleeve 14 is coaxially rotatable with the support column 11, and the bottom end is connected to the movable column 13 through threaded cooperation.

[0055] The top of the movable column 13 is in the shape of a rectangular block, and the inside of the support column 11 is in the shape of a rectangular hole adapted to the rectangular block, so that the movable column 13 and the support column 11 slide together in a single degree of freedom along the axial direction of the support column 11. A rotating sleeve 14 is provided at the bottom of the support column 11, and the movable column 13 is pushed out of the support column 11 or retracted and embedded in the support column 11 by rotating the rotating sleeve 14 in a forward or reverse direction, which is simple and convenient to operate.

[0056] In this embodiment, a conical head 15 which is larger at the top and smaller at the bottom is fixedly connected to the bottom of the movable column 13 , and the outer diameter of the bottom of the movable column 13 is smaller than the outer diameter of the top of the conical head 15 .

[0057] The movable column 13 is fixed to the ground by arranging a conical head 15 at the bottom end of the movable column 13, inserting the movable column 13 and the conical head 15 into the mounting hole, and filling the mounting hole with cement mortar. The cement mortar is hooked by the top surface of the conical head 15 to improve the grip of the support frame and further reduce the risk of the support frame tipping over.

[0058] Among them, the environmental protection monitoring instrument 3 can be a micro environmental air quality monitoring station (DH-AQMS-1000) for monitoring air quality; a dust and noise online monitoring system (S-CGRY) for monitoring dust and noise; a PC-2-T2 photovoltaic power station environmental monitoring system for monitoring ambient temperature and humidity, component temperature, wind speed and direction, and air pressure, etc.
