Description

Technical Field

[0001] This utility model relates to the technical field of gas detection and acquisition equipment, specifically a height-adjustable sampling probe bracket for high-altitude exhaust gas monitoring. Background Technology

[0002] Monitoring waste gas emissions is a crucial aspect of environmental protection supervision during industrial production.

[0003] Currently, the emission of exhaust gases at high altitudes (such as chimney emissions, etc.) is being addressed. Figure 1 As shown, chimneys currently have pre-installed structures at a certain height for sampling probes to insert for sampling (such as pre-drilled sampling holes). When conducting sampling monitoring, the sampling probes typically need to be fixed at a high location to accurately collect exhaust gas samples. However, most existing sampling probe supports are fixed structures, making it difficult to adjust the probe position after installation. When maintenance, calibration, or replacement of the probes is required, maintenance personnel often need to climb to a high position using aerial work platforms or scaffolding, which is not only cumbersome and inefficient but also poses significant safety risks associated with working at height. Furthermore, fixed supports are ill-suited to the sampling needs of chimneys of different heights, lacking flexibility.

[0004] Therefore, there is a need to provide a sampling probe bracket that is highly adjustable, easy to maintain and operate, and has good stability, in order to improve the safety and convenience of high-altitude exhaust gas monitoring. Utility Model Content

[0005] The purpose of this invention is to provide a height-adjustable sampling probe bracket for high-altitude exhaust gas monitoring, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A height-adjustable sampling probe bracket for high-altitude exhaust gas monitoring is characterized by comprising a base and a thick rod vertically fixed to the top surface of the base. The base is fixed to a horizontal bottom surface by ground anchors to keep the thick rod vertically stable. A thin rod is vertically fixed to the top surface of the thick rod, and symmetrical vertical grooves are formed on the front and back of the thin rod. A bearing device is slidably connected through the vertical grooves. The bearing device is also fixedly connected to a height adjustment mechanism installed on the probe bracket. The height adjustment mechanism pulls the bearing device to slide to adjust it to the required height.

[0008] Furthermore, the bearing device includes a horizontal bearing plate with a notch formed on one end face. Sliding blocks that are slidably connected to the sliding groove are fixedly installed on the inner walls of both ends of the notch. A sampling probe is installed on the top surface of the horizontal bearing plate through a moving mechanism. The moving mechanism drives the sampling probe to move horizontally to insert into the chimney that emits exhaust gas for exhaust gas sampling. An inverted U-shaped frame is also fixedly erected in the middle of the top surface of the horizontal bearing plate. The inverted U-shaped frame is fixedly connected to the height adjustment mechanism.

[0009] Furthermore, the moving mechanism includes a shaft frame fixedly mounted on the free end face of the horizontal bearing plate, a lead screw motor mounted on the top surface of the horizontal bearing plate, the lead screw end of the lead screw motor being rotatably connected to the shaft frame, the lead screw of the lead screw motor being threadedly connected to a mounting plate, and a sampling probe being mounted on the top surface of the mounting plate; a pair of guide rods coaxially arranged with the lead screw of the lead screw motor are fixedly connected between the top surface of the horizontal bearing plate and the shaft frame, and the guide rods are slidably connected.

[0010] Furthermore, the height adjustment mechanism includes an adjustment motor fixedly installed on the side of the thicker rod, a pair of guide wheel sets symmetrically fixedly installed on the top of the thinner rod, and a traction rope; one end of the traction rope is fixedly connected to the bearing device, the middle section of the traction rope is wound around the guide wheel set in sequence, and finally the other end of the traction rope is led out and fixedly connected to the winding drum of the adjustment motor.

[0011] Furthermore, the adjusting motor is mounted to the side of the thick rod via a suspension plate, the suspension plate is fixedly connected to the side of the thick rod, and the adjusting motor is fixedly mounted on the bottom surface of the suspension plate.

[0012] Furthermore, a protective cover is fixedly provided at the top of the thin rod, and the protective cover is placed directly above the thin rod to protect the height adjustment mechanism.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, by setting a height adjustment mechanism in conjunction with a sliding connection bearing device, can flexibly and accurately adjust the height position of the sampling probe according to monitoring needs. It is especially convenient to lower the probe to a lower position during maintenance, so that operators can complete the inspection, cleaning, calibration or replacement of the probe without climbing, which greatly reduces the risk of working at height and the labor intensity.

[0015] 2. The support structure of this utility model adopts a combination of thick and thin rods, and achieves overall stable installation through ground anchors, ensuring the stability of the support under the influence of external factors such as high-altitude winds; at the same time, the bearing device integrates a moving mechanism for horizontally movable probes, enabling the probes to accurately extend into the chimney for sampling, improving the accuracy and reliability of monitoring data.

Detailed Implementation

[0023] 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.

[0024] like Figures 1 to 6As shown, this utility model provides a height-adjustable sampling probe bracket for high-altitude exhaust gas monitoring. Its core feature is the ability to adjust the height of the sampling probe 100, facilitating ground maintenance. Specifically, the bracket includes a base 1 for providing stable support. Preferably, the base 1 adopts a plate-like structure with a certain weight and area to enhance overall stability. A thick rod 2 is vertically fixed to the top surface of the base 1, serving as the main support for the entire bracket. Furthermore, to ensure that the thick rod 2 always remains vertically stable, ground anchors 3 are provided on the base 1. Specifically, the ground anchors 3 can be expansion bolts or embedded parts, etc., which securely fix the base 1 to a horizontal ground surface, such as a concrete platform or a specially cast foundation.

[0025] A thin rod 4 is vertically fixed to the top surface of the thick rod 2. The thin rod 4 and the thick rod 2 together form the upright part of the support. This combination of thick and thin rods ensures the strength of the bottom support while reducing the weight of the top structure. Furthermore, symmetrical vertical grooves 5 are machined on the front and rear sides of the thin rod 4. These vertical grooves 5 serve as guide rails, through which a support device 6 is slidably connected to the thin rod 4. Specifically, the support device 6 is used to install and support the sampling probe 100 and its related moving parts.

[0026] To drive the support device 6 to move up and down along the vertical slide 5, this invention is equipped with a height adjustment mechanism 7. Specifically, the height adjustment mechanism 7 is fixedly installed on the probe bracket and fixedly connected to the support device 6. By controlling the height adjustment mechanism 7, the support device 6 can be pulled up and down along the slide 5, thereby adjusting the sampling probe 100 installed on it to the height position required for monitoring, or lowering it to a lower position for convenient operation during maintenance.

[0027] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the specific structure of the supporting device 6 is further refined: it includes a horizontally positioned horizontal supporting plate 61. A notch is formed on one end face of the horizontal supporting plate 61, allowing the supporting plate to better fit against the thin rod 4. Slider blocks 62 are fixedly mounted on the inner walls at both ends of the notch. Preferably, the sliders 62 can be made of wear-resistant materials, such as nylon or oil-impregnated bearings, which form a sliding fit with the vertical grooves 5 on the thin rod 4, ensuring smooth and stable lifting of the supporting device 6. A moving mechanism 63 is installed on the top surface of the horizontal supporting plate 61, and the sampling probe 100 is mounted on the moving mechanism 63. The moving mechanism 63 can drive the sampling probe 100 to move horizontally, allowing it to be inserted into the chimney 200 emitting exhaust gas for sampling as needed, and then retracted after sampling to avoid long-term exposure. Furthermore, an inverted U-shaped frame 64 is fixedly erected across the middle of the top surface of the horizontal supporting plate 61. The inverted U-shaped frame 64 serves as a connection point, with its top fixedly connected to the aforementioned height adjustment mechanism 7, allowing the traction force to be effectively applied to the entire load-bearing device 6. Furthermore, in practical applications, the moving mechanism 63 and the sampling probe 100 need to be electrically connected to the main control system located on the ground (the electrical connection structure is not shown in the attached diagram) to achieve data transmission and control. Therefore, when setting up the electrical connection wires, a certain length of wire should be reserved to accommodate height adjustments and prevent damage from pulling.

[0028] For the preferred implementation scheme of mobile mechanism 63, see [link to relevant documentation]. Figure 2 and Figure 5 Specifically, the moving mechanism 63 includes a shaft frame 631 fixedly mounted on the free end face of the horizontal support plate 61 (i.e., the end away from the thin rod 4). A lead screw motor 632 is mounted on the top surface of the horizontal support plate 61. The lead screw end of the lead screw motor 632 is rotatably connected to the shaft frame 631. A mounting plate 633 is threadedly connected to the lead screw of the lead screw motor 632, and the sampling probe 100 is fixedly mounted on the top surface of this mounting plate 633. When the lead screw motor 632 operates, it drives the lead screw to rotate, thereby causing the mounting plate 633 and the probe to move horizontally along the lead screw axis. Simultaneously, to ensure the smoothness of the movement and prevent the mounting plate 633 from rotating or shifting, a pair of guide rods 634 are fixedly connected between the top surface of the horizontal support plate 61 and the shaft frame 631. This pair of guide rods 634 are coaxially arranged with the lead screw of the lead screw motor 632, and the mounting plate 633 is slidably connected to the guide rods 634. The guide rods 634 provide good guidance and support.

[0029] like Figures 1 to 5As shown, a preferred embodiment of the height adjustment mechanism 7 includes: an adjustment motor 71 fixedly mounted on the side of the thicker rod 2, a pair of guide wheel sets 72 symmetrically fixedly mounted on the top of the thinner rod 4, and a traction rope 73. One end of the traction rope 73 is fixedly connected to the inverted U-shaped frame 64 of the bearing device 6. The middle section of the traction rope 73 is wound around the pair of guide wheel sets 72 in sequence. The guide wheel sets 72 change the direction of the traction rope 73 and distribute the lifting force evenly. Finally, the other end of the traction rope 73 is led down and fixedly connected to the winding drum of the adjustment motor 71. By controlling the forward and reverse rotation of the adjustment motor 71, the traction rope 73 can be wound or released, thereby raising or lowering the bearing device 6. To ensure the stability of the installation of the adjustment motor 71, the adjustment motor 71 is further mounted to the side of the thicker rod 2 via a suspension plate 8. Specifically, one end of the suspension plate 8 is fixedly connected to the side of the thicker rod 2, and the adjustment motor 71 is fixedly mounted on the bottom surface of the suspension plate 8. This suspended installation saves space and has a compact structure.

[0030] Furthermore, it's worth noting that after installing the sampling probe bracket, the first use still requires manual climbing to align the sampling probe 100 with the chimney 200 at the correct sampling height. Then, a mark should be made at a suitable position on the traction rope 73 (e.g., ...). Figure 3 As shown in one embodiment: a horizontal mark is drawn at the position of the traction rope 73 flush with the suspension plate 8. Subsequent maintenance can be carried out by adjusting the sampling height of the sampling probe 100 and the chimney 200 through this mark.

[0031] This invention is typically used outdoors, and its main components, such as the sampling probe 100 and the regulating motor 71, are usually waterproof and sunproof.

[0032] However, considering outdoor environmental factors, in order to protect components such as the guide wheel assembly 72 and the traction rope 73 in the height adjustment mechanism 7 from corrosion by rain, snow, dust, etc., it is preferable that a protective cover 9 is also fixedly installed at the top of the thin rod 4, such as... Figure 2 , Figure 4 and Figure 6 As shown. Preferably, the protective cover 9 is made of metal or engineering plastic, and its size is larger than the cross-section of the thin rod 4, completely covering the thin rod 4 to form a certain protective barrier.

[0033] The working process of this utility model is as follows: First, the base 1 is securely installed on the ground near the monitoring point using the ground anchor 3, ensuring that the thick rod 2 and the thin rod 4 are in a vertical position. Connect the power supply and control lines. During sampling, the traction rope 73 is released by controlling the adjusting motor 71 of the height adjusting mechanism 7, allowing the bearing device 6 to descend to its initial low position along the vertical slide 5 under gravity. The sampling probe 100 is installed on the mounting plate 633 of the moving mechanism 63. Then, the adjusting motor 71 is controlled to wind up the traction rope 73, which is guided by the guide wheel group 72 to pull the bearing device 6 upward until the sampling probe 100 reaches a height approximately level with the sampling port of the chimney 200. Next, the screw motor 632 of the moving mechanism 63 is started, driving the mounting plate 633 to move the sampling probe 100 horizontally, so that its probe part extends into the chimney 200 to sample the exhaust gas. After sampling is completed, first control the lead screw motor 632 to reverse, causing the sampling probe 100 to exit the chimney 200. Then control the adjusting motor 71 to lower the supporting device 6 to a lower position or the ground, allowing for convenient maintenance, replacement, or data reading of the sampling probe 100. Throughout the process, operators do not need to climb to high places, making it safe and convenient.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
