Description

Technical Field

[0001] The utility model relates to the technical field of waste gas monitoring, in particular to a waste gas sampling support frame with a self-moving function. Background Art

[0002] Exhaust gas monitoring is an important part of environmental management. During the monitoring process, sampling is usually carried out first, and then sample analysis is performed to obtain the corresponding monitoring data. Exhaust gas sampling must be carried out in accordance with the requirements of GB / T16157-1996 for regular and fixed-point sampling, that is, multiple sampling points must be set according to the coverage width of the pollution source, and each sampling point must stay for no less than 3 minutes for sampling operations. Taking the chimney pollution source as an example, most people will use a smoke gun of a certain length for multi-point sampling. One end of the smoke gun is the sampling end, and most of the time a sensor is installed at this end to monitor the basic data of the chimney in real time, such as smoke temperature, flow rate, air volume, etc. The other end of the smoke gun is the collection end, and most of the time a sampling cylinder is connected to this end, and it is also connected to a host with a pump. When the pump is started, the smoke at the sampling end can be collected into the sampling cylinder through the smoke gun. When taking samples at fixed points at regular intervals, a support frame is usually used to support the middle area of ​​the pipe. The pipe is then manually controlled to control the time and move its position to cover the entire chimney outlet area. During this process, the pipe needs to be unlocked, moved, and fixed repeatedly, which is not only time-consuming and labor-intensive, but also the accuracy of the movement displacement cannot be guaranteed.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] like Figure 1-7 As shown, the exhaust gas sampling support frame with self-moving function includes a frame body 1, and a positioning and moving mechanism 9 is provided on the top of the frame body 1;

[0034] The positioning and moving mechanism 9 includes a lower card seat 97 and an upper card seat 91 detachably connected to the lower card seat 97. The top end of the lower card seat 97 is penetrated by a concave lower positioning slot 13, and the bottom end of the upper card seat 91 is penetrated by a concave upper positioning slot 6. The lower positioning slot 13 and the upper positioning slot 6 together form a sliding through hole that allows the cigarette gun to move.

[0035] The upper holder 91 is provided with a notch 94 communicating with the upper positioning slot 6;

[0036] A driven gear 95 located at the notch 94 is rotatably provided on the upper clamping seat 91 . A moving drive assembly for driving the driven gear 95 to rotate is also provided on the upper clamping seat 91 .

[0037] like Figure 2 As shown, the cigarette gun has a gun arm section 10, with a sampling section 103 at one end and a collection section at the other end. Gun arm section 10 is provided with a plurality of tooth grooves 101 that can cooperate with driven gear 95, and the plurality of tooth grooves 101 are arranged in a front-to-back manner on gun arm section 10.

[0038] When in use, the upper clamping seat 91 is connected to the lower clamping seat 97, the upper positioning sliding groove 6 and the lower positioning sliding groove 13 can jointly form a sliding through hole clamping the gun arm segment 10, at this time, the driven gear 95 is in meshing relationship with the specific tooth groove 101. Starting the moving driving assembly can drive the driven gear 95 to rotate by a specific angle, and through the meshing relationship between the driven gear 95 and the tooth groove 101, the gun arm segment 10 can be driven to advance or retreat by one unit, and after the sampling point is sampled for a specific time, the gun arm segment 10 is moved again through the moving driving assembly. When the driven gear 95 is not rotated, the position state of the gun arm segment 10 can be locked through the meshing relationship between the driven gear 95 and the tooth groove 101, so as to ensure the stability of sampling.

[0039] Preferably, the upper clamping seat 91 and the lower clamping seat 97 are detachably connected through bolts.

[0040] It can be seen that the embodiment can move the smoke gun to a specific position without disassembling and assembling the smoke gun, and can also position the smoke gun during sampling, which can effectively reduce the workload and improve the efficiency and quality of monitoring.

[0041] Preferably, the moving driving assembly comprises a moving driving device 93 installed on the upper clamping seat 91, and the output end of the moving driving device 93 is connected with a driving gear 96 engaged with the driven gear 95.

[0042] In the embodiment, the moving driving device 93 can be a speed reducer motor, and starting the speed reducer motor can drive the driving gear 96 to rotate, and through the meshing relationship between the driving gear 96 and the driven gear 95, the gun arm segment 10 can be driven to advance or retreat by one unit.

[0043] If the start and stop time of the speed reducer motor is set, the moving driving of the smoke gun can be realized in a specific time, which can further reduce the manual workload. The control of the speed reducer motor can be realized through a control panel arranged on the frame 1 or remote control, which will not be described here.

[0044] In order to avoid impurities entering the moving driving assembly, a cover 8 can be connected to the upper clamping seat 91 to shield the moving driving assembly.

[0045] Preferably, one end of the upper clamping seat 91 is hinged to one end of the lower clamping seat 97.

[0046] The other end of the upper clamping seat 91 is provided with a buckle 92, and the other end of the lower clamping seat 97 is provided with a clamping groove 98 matched with the buckle 92.

[0047] In the embodiment, the hinge relationship between the upper clamping seat 91 and the lower clamping seat 97 can facilitate the assembly and disassembly of the smoke gun, and the clamping cooperation between the buckle 92 and the clamping groove 98 can facilitate the detachable connection between the upper clamping seat 91 and the lower clamping seat 97.

[0048] In order to improve the stability of the engagement between the buckle 92 and the slot 98, preferably, locking protrusions 99 are provided on both sides of the end of the buckle 92;

[0049] The locking slot 98 is provided with a locking groove 911 that cooperates with the locking protrusion 99 .

[0050] In this embodiment, the locking protrusion 99 can be made of an elastic material, such as rubber, silicone, etc. When the buckle 92 is inserted into the slot 98, the locking protrusion 99 deforms and fits into the locking groove 911, locking the buckle 92 in place and preventing the upper base 91 from accidentally separating from the lower base 97.

[0051] Preferably, a locking rod 910 is threadedly connected to the lower clamping seat 97 , the inner end of the locking rod 910 can pass through the wall of the lower clamping seat 97 and be located in the clamping groove 98 , and the outer end of the locking rod 910 is connected to a locking knob 915 .

To enhance the abutment and locking effect, the side end surface of the buckle 92 can be provided with a locking groove 916 that partially accommodates the locking rod 910.

[0053] As another preferred locking method, after the locking rod 910 is placed in the card slot 98, it is located above the locking groove 911. In this way, if the buckle 92 moves upward accidentally, the locking rod 910 will also block the upward movement of the locking protrusion 99.

[0054] Preferably, a recessed limiting groove 12 is formed on the wall surface of the lower positioning slot 13 , and the limiting groove 12 passes through the front and rear ends of the lower clamping seat 97 .

[0055] In this embodiment, the gun arm section 10 should be provided with a limiting protrusion that can be inserted into the limiting groove 12. In this way, when the gun arm section 10 moves in the sliding through hole, the stability of the movement of the gun arm section 10 can be improved through the cooperation between the limiting protrusion and the limiting groove 12.

[0056] Preferably, a flexible gasket layer 14 is provided on the bottom surfaces of the upper positioning chute 6 and the lower positioning chute 13 .

[0057] In this embodiment, the provision of the flexible gasket layer 14 can prevent the gun arm section 101 from being scratched.

[0058] Preferably, a positioning drive device 912 is provided on the upper card seat 91 , and an output end of the positioning drive device 912 is connected to a positioning rod 913 that can pass through the upper card seat 91 up and down and can be located in the area of ​​the upper positioning slot 6 .

The positioning drive device 912 can be a motor lock or the like.

[0060] In order to improve the positioning stability of the gun arm section 10 , preferably, a brake pad 914 is connected to the end of the positioning rod 913 .

[0061] Preferably, the positioning movement mechanism 9 is arranged on the top of the frame 1 through an adjustment component;

[0062] The adjustment assembly includes a fine-tuning seat assembly, the top of which is provided with a support seat 15, and the lower clamping seat 97 is rotatably connected to the support seat 15;

[0063] The adjustment assembly also includes a fixing rod 7 for fixing the state of the lower clamping seat 97. The inner end of the fixing rod 7 passes through the lower clamping seat 87 and is threadedly connected to the support seat 15. The outer end of the fixing rod 7 is connected to a fixing knob 16.

[0064] In this embodiment, after the frame 1 is placed, the working area covered by the sampling section 103 can be adjusted by adjusting the angular position of the lower clamping base 97 relative to the supporting base 15 .

[0065] Preferably, the fine-tuning seat assembly includes an upper fixing plate 5 connected to the bottom end of the support seat 15 and a lower fixing plate 2 connected to the top end of the frame 1, the top end of the lower fixing plate 2 is provided with a universal seat 11, and the bottom end of the upper fixing plate 5 is provided with a universal ball 3 that can roll with the universal seat 11;

[0066] The fine-tuning seat assembly further includes a plurality of fine-tuning drive devices 4 , the fixed end of the fine-tuning drive device 4 is hinged to the top end of the lower fixed plate 2 , and the telescopic end of the fine-tuning drive device 4 is hinged to the bottom end of the upper fixed plate 5 .

[0067] In this embodiment, when the area where the frame 1 is placed is non-planar, or when the frame 1 is non-horizontal after being extended, the horizontal position of the cigarette gun 10 can be adjusted using the fine-tuning seat assembly. Specifically, the extension and retraction of the fine-tuning drive device 4 is adjusted accordingly according to the tilt angle. The universal ball 3 and universal seat 11 cooperate to provide adaptive support for the various angles of the upper fixing plate 5. The fine-tuning drive device 4 can optionally be an electric push rod, etc.
