Description

Technical Field

[0001] This utility model relates to the field of sampling equipment technology, and in particular to a smoke and dust sampling device. Background Technology

[0002] In fields such as environmental monitoring and industrial emission detection, dust sampling devices are important equipment for collecting pollutants such as particulate matter and dust in the air. As a key component of dust sampling devices, the stability and positional accuracy of the sampling gun during the sampling process directly affect the reliability of the sampling data. Currently, sampling guns usually need to be supported by a bracket to ensure that they maintain a fixed posture during the sampling process and avoid sampling errors caused by manual handling or unstable support.

[0003] The support structures (such as clamping parts and support grooves) of some existing sampling gun holders are mostly designed with fixed dimensions, which can only be adapted to sampling guns of specific diameters or lengths. When the specifications of the sampling gun (such as tube diameter and weight) change, it is impossible to achieve stable support by adjusting the dimensions of the support structure. For example, if the tube diameter of the sampling gun is large, the fixed-size arc groove may not fit tightly, causing the sampling gun to shake. If the tube diameter is small, it may fall off due to loose clamping.

[0004] Therefore, developing a device that facilitates the support of sampling guns is of significant practical value and technical importance in addressing the technical bottlenecks faced by the industry. Summary of the Invention

[0005] The purpose of this invention is to provide a smoke and dust sampling device that is applicable to sampling guns of different specifications.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a dust sampling device, comprising a dust sampler body, a sampling tube, a sampling gun, and a support assembly. One side of the sampling tube is fixedly connected to the dust sampler body, and the other side of the sampling tube is fixedly connected to the sampling gun. The support assembly is placed on one side of the dust sampler body to support the sampling gun. The support assembly includes a tripod and a support body. The support body is mounted on the tripod. An adjusting rod is slidably connected within the support body. A locking mechanism for fixing the position of the adjusting rod is provided between the support body and the adjusting rod. An adjusting frame is fixed to one end of the adjusting rod. Two arc-shaped supports are provided on the adjusting frame, forming an arc-shaped channel for supporting the sampling gun between the two arc-shaped supports. An arc-shaped plate is fixed to the rear end of the support body for placing the sampling gun. An adjusting mechanism for adjusting the position of the two arc-shaped supports is provided within the adjusting frame. A connecting mechanism for mounting the support body is provided between the support body and the tripod.

[0007] Preferably, the locking mechanism includes a limiting bolt, a first through hole is provided on the bracket body, and a second through hole is provided on the adjusting rod. When the first through hole on the bracket body and any of the second through holes on the adjusting rod are aligned, they are fixedly connected by the limiting bolt.

[0008] Preferably, the adjustment mechanism includes a bidirectional lead screw rotatably mounted inside the adjustment frame, and sliders are fixed at the lower ends of the two arc-shaped supports. The sliders are slidably connected within the adjustment frame and threadedly connected to the bidirectional lead screw.

[0009] Preferably, one end of the bidirectional lead screw passes through the adjustment frame and is fixed with a handle.

[0010] Preferably, the connecting mechanism includes a limiting rod fixed to the rear end of the support body, a limiting hole is opened at the upper end of the tripod, the limiting rod is installed in the limiting hole, and a limiting mechanism for limiting the limiting rod is provided on the tripod.

[0011] Preferably, a support plate is fixed to the front end of the tripod, and an arc-shaped rod is fixed to the lower end of the support body, with the arc-shaped rod overlapping the support plate.

[0012] Preferably, the limiting mechanism includes a fastening knob, and a threaded hole is provided on one side of the limiting hole on the tripod. The fastening knob is threadedly connected to the threaded hole on the tripod and then tightly fits against the limiting rod.

[0013] Compared with existing technologies, the advantages of this invention are as follows: By designing an adjustable arc-shaped bracket, it can adapt to sampling guns of different diameters or lengths, solving the problem that existing brackets, due to their fixed dimensions, cannot accommodate various specifications of sampling guns. This makes the device more flexible in meeting different sampling needs, improving its versatility and practicality. Through the design of the tripod and bracket body, as well as the slidingly connected adjusting rod and locking mechanism within the bracket body, the device can ensure the stability and positional accuracy of the sampling gun during the sampling process. This avoids sampling errors caused by manual handling or unstable support, improving the reliability of the sampling data. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0017] like Figure 1-5 As shown, a dust sampling device includes a dust sampler body 1, which is fixedly connected to a sampling gun 3 via a sampling tube 2 to form a sampling path. A support assembly is disposed on one side of the dust sampler body 1, including a tripod 4 and a support body 5.

[0018] The tripod 4 has a triangular support structure at its bottom to ensure that the device remains stable during sampling. A limiting hole 8 is opened at its upper end for mounting the support body 5. A limiting rod 7 is fixed at the rear end of the support body 5. The limiting rod 7 is inserted into the limiting hole 8 of the tripod 4 to achieve initial positioning.

[0019] The tripod 4 is equipped with a fastening knob 9, whose threaded hole is connected to the limiting hole 8. Rotating the fastening knob 9 to press it against the limiting rod 7 can fix the position of the support body 5 and prevent shaking. The front end of the tripod 4 is fixed with a support plate 12, and the arc-shaped rod 11 at the lower end of the support body 5 overlaps on the support plate 12. The arc-shaped surface contact enhances the support stability and prevents the support body 5 from tilting forward.

[0020] An adjusting rod 6 is slidably connected inside the support body 5. The adjusting rod 6 can move up and down along the support body 5 to adjust the support height of the sampling gun 3. The support body 5 has a first through hole 18, and multiple second through holes 19 are evenly distributed along the length of the adjusting rod 6. When the adjusting rod 6 moves to the target height, the first through hole 18 is aligned with the corresponding second through hole 19. The limiting bolt 20 is then inserted and tightened to fix the position of the adjusting rod 6.

[0021] The rear end of the support body 5 is fixed with an arc plate 10, the curvature of which matches the outer wall of the sampling gun 3. This plate can serve as an auxiliary support point to share the weight of the sampling gun 3.

[0022] An adjustment frame 13 is fixed at the top of the adjustment rod 6. Two arc-shaped supports 14 are set on the adjustment frame 13, forming an arc-shaped channel between them for holding the sampling gun 3. A bidirectional lead screw 16 is rotatably installed inside the adjustment frame 13, with the threads at both ends in opposite directions. Slider 15 is fixed at the lower ends of the two arc-shaped supports 14 respectively. The slider 15 is threadedly connected to the bidirectional lead screw 16 and can slide inside the adjustment frame 13.

[0023] Rotating the handle 17 at one end of the bidirectional lead screw 16 causes the sliders 15 on both sides to move the arc-shaped support 14 inward or outward simultaneously, thereby adjusting the width of the arc-shaped channel. For example, when the diameter of the sampling gun 3 is relatively large, rotating the handle 17 counterclockwise expands the arc-shaped support 14; when the diameter is relatively small, rotating the handle 17 clockwise retracts the arc-shaped support 14 until it fits tightly against the outer wall of the sampling gun 3.

[0024] The device uses a sampling tube 2 to fix the dust sampler body 1 and the sampling gun 3 together, forming a pollutant collection path. The support assembly, as the core stabilizing structure, consists of a tripod 4 and a support body 5: the tripod 4 provides basic support, and the support body 5 provides dynamic support for the sampling gun 3 through components such as an adjusting rod 6 and an adjusting frame 13. The support assembly and the sampler body are placed side-by-side and mechanically connected to form a complete sampling system.

[0025] The tripod 4 has three legs at its bottom that support the ground to resist external interference. Its upper limit hole 8 cooperates with the limit rod 7 of the support body 5 to achieve initial positioning. The front support plate 12 overlaps with the arc-shaped rod 11 of the support body 5, and the arc-shaped surface contact forms a support structure to prevent the support body 5 from tilting forward and ensure the stability of the overall structure.

[0026] The adjusting rod 6 inside the support body 5 can slide axially, and the second through holes 19 evenly distributed on its surface form a height adjustment interface with the first through hole 18 of the support body 5. When it is necessary to adjust the height of the sampling gun 3, the adjusting rod 6 is manually moved up and down to align the through holes at the target height.

[0027] The limiting bolt 20 serves as the core locking component. After being inserted into the aligned through hole, it is tightened, and the adjusting rod 6 is fixed inside the bracket body 5 by the friction between the bolt and the hole wall.

[0028] The two-way lead screw 16 inside the adjustment frame 13 has opposite threads at both ends. When the handle 17 is turned, the lead screw drives the sliders 15 on both sides to move towards or away from each other. The sliders 15 are fixedly connected to the arc-shaped bracket 14, thereby driving the arc-shaped bracket 14 to adjust the spacing synchronously. When the handle 17 is turned counterclockwise, the two-way lead screw 16 causes the sliders 15 to move to both sides, and the arc-shaped bracket 14 expands outward, increasing the width of the arc-shaped channel to accommodate the large-diameter sampling gun 3. When the handle 17 is turned clockwise, the sliders 15 drive the arc-shaped bracket 14 to retract inward, reducing the channel width until the inner wall is tightly attached to the outer wall of the sampling gun 3.

[0029] The arc-shaped plate 10 at the rear end of the support body 5 and the arc-shaped bracket 14 form a double support structure. The arc-shaped plate 10 fixes and supports the middle of the sampling gun 3 and shares the weight. The arc-shaped bracket 14 dynamically adjusts the clamping force. The combination of the two ensures that the sampling gun 3 remains stable in both the horizontal and vertical directions.

[0030] The limiting rod 7 is inserted into the limiting hole 8 of the tripod 4 to complete the initial positioning. At this time, the arc rod 11 naturally overlaps on the support plate 12 to form an initial stable structure. The fastening knob 9 is pressed against the limiting rod 7 through the threaded hole. When the knob is rotated, radial pressure is generated to fix the limiting rod 7 in the limiting hole 8, preventing the support body 5 from rotating or shifting horizontally, and ensuring that the support assembly does not shake during the sampling process.

[0031] When in use, place the tripod 4 on a stable ground, install the bracket body 5 through the limit rod 7 and the fastening knob 9, and ensure that the arc rod 11 overlaps the support plate 12. According to the height requirements of the sampling gun 3, adjust the height of the adjusting rod 6 and lock it through the limit bolt 20. Turn the handle 17 to adjust the spacing of the arc bracket 14 so that the sampling gun 3 is placed stably between the arc channel and the arc plate 10.

[0032] During sampling, the weight of the sampling gun 3 is supported by the arc-shaped bracket 14 and the arc-shaped plate 10 to prevent shaking caused by hand. If the sampling position changes, the support height and tube diameter clamping force can be quickly adjusted by the adjusting rod 6 and the two-way screw 16 to ensure the accuracy of the sampling data.

[0033] By combining the bidirectional lead screw 16 with the arc-shaped bracket 14, it can be adapted to sampling guns with different pipe diameters such as φ20mm-φ50mm, thus overcoming the limitations of existing fixed-size brackets. The tripod 4, the arc-shaped rod 11 and the support plate 12 form a triangular support structure. Combined with the double locking of the limit bolt 20 and the fastening knob 9, it ensures that the device does not shake during the sampling process.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
