Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring auxiliary equipment technology, specifically a fixed bracket for a portable exhaust pipe sampling gun. Background Technology

[0002] In the industrial production sector, chemical enterprises and other production units often discharge industrial waste gases through exhaust stacks. These waste gases often contain toxic and harmful air pollutants such as sulfur dioxide, nitrogen oxides, and volatile organic compounds. To effectively prevent enterprises from illegally discharging toxic waste gases and causing environmental pollution, it is necessary to conduct routine sampling and monitoring of the waste gases in the exhaust stacks in accordance with environmental protection regulations.

[0003] Currently, exhaust gas sampling and monitoring operations are mostly conducted outdoors, and in some cases, at high altitudes, facing complex weather conditions and stringent operational space limitations. According to industry standards, a single sampling monitoring session should typically last no less than two hours. To ensure the accuracy of the monitoring data, testing personnel must hold the testing gun or sampling gun for extended periods. However, due to the long monitoring time and harsh working environment, testing personnel are prone to fatigue, leading to deviations in the spatial position and angle of the sampling equipment. This ultimately introduces significant sampling errors, affecting the reliability and validity of the monitoring data.

[0004] Currently, most portable fixed pollution source particulate matter sampling supports on the market are mainly composed of a triangular support with branch pipes inserted inside the central tube, and a stock for supporting the sampling gun mounted on the upper end of the branch pipes. While this type of support reduces the intensity of manual operation and improves sampling accuracy to some extent, it has significant limitations in practical applications. On the one hand, this structure requires a large working platform area; on the other hand, its applicable scenarios require the sampling tube orifice of the exhaust stack to be horizontal. When the working platform area at the monitoring site is limited, or when the sampling tube orifice is vertically upward, downward, or oriented in other non-horizontal directions, this type of support cannot be used normally, greatly limiting its application range and flexibility. Utility Model Content

[0005] The purpose of this invention is to provide a fixed bracket for a portable exhaust pipe sampling gun to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixed bracket for a portable exhaust pipe sampling gun, comprising a base and a fixing mechanism and a clamping mechanism respectively disposed at both ends of the base length. The fixing mechanism is used to fix the sampling tube on the exhaust pipe, and the clamping mechanism is used to fix the sampling gun so that the sampling gun is facing the sampling tube for sampling.

[0007] Furthermore, the fixing mechanism includes a fixing frame fixed on the base and a top plate adjustable inside the fixing frame via a first linear drive member. The top plate is used to press the sampling tube against the outer wall of the base, and the first linear drive member is used to adjust the distance between the top plate and the outer wall of the base.

[0008] Furthermore, the first linear drive component is a screw threadedly connected to the fixed frame, with one end of the screw extending to the outside of the fixed frame and a knob fixed thereon, and the other end of the screw rotatably connected to the top plate.

[0009] Furthermore, the clamping mechanism includes a first bracket and a second bracket with opposite openings. The first bracket is fixedly connected to the base via a connecting plate. The first bracket and the second bracket are hinged to one side, and a fixing plate is provided on the other side of both the first bracket and the second bracket. The two fixing plates are fixedly connected by a locking member.

[0010] Furthermore, the clamping mechanism also includes a clamping plate disposed inside the first bracket and the second bracket, and a second linear drive member that drives the clamping plate to move back and forth radially along the first bracket or the second bracket.

[0011] Furthermore, the base includes an outer tube and an inner tube that is movably inserted into the outer tube. A positioning element is provided between the outer tube and the inner tube. The fixing mechanism and the clamping mechanism are respectively located at opposite ends of the outer tube and the inner tube.

[0012] Furthermore, the positioning element is a threaded rod fixed on the outer peripheral wall of one end of the inner tube. The outer wall of the outer tube is provided with a clearance sliding hole to accommodate the threaded rod sliding back and forth along the length of the outer tube. The threaded rod extends through the clearance sliding hole to the outside of the outer tube and is threadedly connected to a locking nut.

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

[0014] (1) The clamping and fixing design of the clamping mechanism completely replaces the traditional method of manually holding the sampling gun, effectively avoiding the displacement of the sampling equipment caused by human fatigue, thereby greatly reducing the labor intensity of the test personnel and significantly improving the accuracy and reliability of the sampling data.

[0015] (2) The breakthrough adopts a fixed mechanism locking installation method, which does not require the use of a working platform. It can be directly fixed to the outer wall of the exhaust pipe sampling tube in any direction. Whether the sampling tube is installed horizontally, vertically or inclined, it can be quickly installed and operated stably, which greatly expands the scope of applicable scenarios.

[0016] (3) The bracket is also characterized by its simple structure, convenient assembly and disassembly, and easy portability. It adopts standardized component design, which effectively reduces manufacturing costs and has good market promotion value and economic benefits. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example 1, please refer to Figure 1-2This utility model provides an embodiment of a fixed bracket for a portable exhaust pipe sampling gun, comprising a base 1 and a fixing mechanism 2 and a clamping mechanism 3 respectively disposed at both ends of the base 1. The fixing mechanism 2 is used to fix the sampling tube 401 on the exhaust pipe 4. The fixing mechanism 2 includes a fixing frame 201 fixed on the base 1 and a top plate 203 adjustablely disposed inside the fixing frame 201 via a first linear drive member 202. The top plate 203 is used to press the sampling tube 401 against the outer wall of the base 1. The first linear drive member 202 is used to adjust the distance between the top plate 203 and the outer wall of the base 1. In this embodiment, the first linear drive member 202 is a screw threaded to the top of the fixing frame 201, and one end of the screw extends to the outer side of the fixing frame 201 and is fixed with a knob. The other end of the screw is rotatably connected to the top plate 203. By rotating the first linear drive member 202, the top plate 203 can be moved closer to or further away from the outer wall of the base 1, so that the base 1 can be clamped and fixed on sampling tubes 401 of different diameters. The top plate 203 has an arc-shaped plate structure. To improve its stability, an anti-slip rubber pad can be installed at the end of the top plate 203 near the sampling cylinder 401. To improve the stability of the linear movement of the top plate 203, a guide rod (not shown in the figure) parallel to the first linear drive component 202 can also be installed on the top plate 203. The guide rod is slidably connected to the fixing frame 201 to prevent rotation during the adjustment of the top plate 203. Through the fixing mechanism 2, the base 1 can be directly fixed to the outer wall of the sampling cylinder 401 on the exhaust pipe 4 in any orientation without relying on the working platform. Whether the sampling cylinder 401 is installed horizontally, vertically, or at an angle, it can be quickly installed and stably operated, greatly expanding the range of applicable scenarios.

[0023] The clamping mechanism 3 is used to fix the sampling gun so that the sampling gun is directly facing the sampling cylinder 401 for sampling. In this embodiment, the clamping mechanism 3 includes a first bracket 301 and a second bracket 302 with opposite openings. Both the first bracket 301 and the second bracket 302 are arc-shaped structures with a semi-circular cross-section. The two are spliced ​​together to form a cylindrical structure with both ends through, and its axis is parallel to the length direction of the base 1. The bottom end of the first bracket 301 is rigidly fixed to the base 1 by two connecting plates 303. The first bracket 301 and the second bracket One side of bracket 302 is hinged, and the other side of both the first bracket 301 and the second bracket 302 is provided with a fixing plate 304. The two fixing plates 304 are fixedly connected by a locking member 305, which can be a bolt and nut. Both fixing plates 304 are provided with through holes to accommodate bolts. When installing the sampling gun, the sampling gun is placed between the first bracket 301 and the second bracket 302, and then the bolt is passed through the through hole on the fixing plate 304. Finally, the nut is used to lock the sampling gun in place. To improve the clamping firmness, anti-slip rubber pads are provided on the inner sidewalls of the first bracket 301 and the second bracket 302. By setting up the clamping mechanism 3, the traditional method of manually holding the sampling gun is replaced, effectively avoiding displacement of the sampling equipment caused by human fatigue, thereby significantly reducing the labor intensity of the testing personnel and significantly improving the accuracy and reliability of the sampling data.

[0024] To facilitate fixing sampling guns of different lengths, in this embodiment, the base 1 is a length-adjustable structure, including an outer tube 101 and an inner tube 102 that is movably inserted into the outer tube 101. A positioning element is provided between the outer tube 101 and the inner tube 102. The fixing mechanism 2 and the clamping mechanism 3 are respectively located at the ends of the outer tube 101 and the inner tube 102 that are far apart from each other. Specifically, the positioning component is a threaded rod 103 fixed on the outer peripheral wall of one end of the inner tube 102. The outer wall of the outer tube 101 is provided with a clearance sliding hole 1011 to accommodate the threaded rod 103 sliding back and forth along the length of the outer tube 101. The threaded rod 103 extends through the clearance sliding hole 1011 to the outside of the outer tube 101 and is threadedly connected to a locking nut 104. When adjusting the length, the threaded rod 103 can slide inside the clearance sliding hole 1011 to play a limiting role. After the adjustment is completed, tightening the locking nut 104 can fix the outer tube 101 and the inner tube 102 relatively. The operation is convenient and quick, and the length of the base 1 can be adjusted according to the length of the sampling gun.

[0025] Working principle: Insert the sampling tube 401 into the inner side of the fixing frame 201, rotate the first linear drive component 202, and drive the top plate 203 to move closer to the sampling tube 401. The top plate 203 presses the sampling tube 401 against the top of the base 1, realizing the relative fixation of the base 1 and the exhaust pipe 4. Loosen the locking nut 104 to adjust the length of the inner tube 102 inserted into the outer tube 101. The threaded rod 103 slides inside the clearance sliding hole 1011 to play a limiting role. The length of the base 1 can be adjusted according to the length of the sampling gun. After adjustment, tighten the locking nut 104 to fix the inner tube 102. Then remove the locking component 305, place the sampling gun between the first bracket 301 and the second bracket 302, and then lock the first bracket 301 and the second bracket 302 with the locking component 305 to clamp and fix the sampling gun. At this time, the sampling head of the sampling gun is facing the sampling tube 401 for sampling.

[0026] Example 2, please refer to Figure 3 Based on Embodiment 1, this embodiment further includes a clamping plate 306 disposed inside the first bracket 301 and the second bracket 302, and a second linear drive 307 that drives the clamping plate 306 to move back and forth along the radial direction of the first bracket 301 or the second bracket 302. The clamping plate 306 has an arc-shaped plate structure, and the second linear drive 307 is a screw threadedly connected to the first bracket 301. The top end of the screw extends to the outside of the first bracket 301 and is fixed with a knob. Its bottom end is located inside the first bracket 301 and is rotatably connected to the clamping plate 306. By rotating the second linear drive 307, the clamping plate 306 is driven to move back and forth along the radial direction of the first bracket 301, which can clamp and fix sampling guns of different sizes. In order to improve the positioning effect, an anti-slip rubber pad is provided on the inner side wall of the clamping plate 306.
