If these dusts cannot be timely controlled, not only the normal operation of the coal conveying equipment will be affected, but also serious harm to the surrounding environment and the health of personnel can be caused. Long-term accumulation of the dusts will cause the equipment components to be worn out intensively, reduce the service life of the machinery, and possibly cause the sensors to be blocked or malfunction, affecting the operation efficiency of the entire coal conveying system. In addition, the high-concentration dust environment can also reduce the heat dissipation performance of the equipment, increase the failure rate of the coal conveying system, and further affect the production safety and economic benefits of the enterprise.

[0003] From the environmental point of view, the dispersion of the coal dusts will cause air pollution and affect the air quality of the surrounding area. Especially in a closed or semi-closed coal conveying passage, the dust concentration is too high, which can cause damage to the respiratory system of the workers and increase the risk of occupational diseases such as pneumoconiosis. At the same time, the dusts are extremely easy to cause dust explosion when encountering open fire or static electricity discharge within a certain concentration range, which can cause serious safety accidents.

[0004] The dust gas detection equipment on the market currently has some problems in the installation and use process.

[0032] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0034] Steady mechanism includes hollow tube 6 and gravity ball 5, and the middle part of hollow tube 6 is fixedly connected in support 3, and the inside of hollow tube 6 is provided with rope 15, and the bottom of hollow tube 6 is threadedly connected with threaded column 16, and gravity ball 5 is fixedly connected at the bottom of threaded column 16, and one end of rope 15 is fixedly connected to the inner top wall of hollow tube 6, and the other end of rope 15 is fixedly connected to the top of threaded column 16, and the outside of support 3 is rotatably connected with rotating plate 4 through connecting column 18, and the outside of rotating plate 4 is fixedly connected with conical column 17. The detector main part 1 is used for detecting the dust and gas concentration in the coal conveying process, to ensure safe production and environmental monitoring. The inserted rod 11 is fixedly connected to the outside of the detector main part 1, which facilitates the installation of the detector main part 1 on the support 3. The support 3 is used for supporting and fixing the detector main part 1, to ensure its stable operation. The installation rod 2 is fixedly connected to the top of the support 3, and the inside of the installation rod 2 is provided with a fixed mechanism, which plays a role in fixing the detector main part 1.

[0035] Steady mechanism includes hollow tube 6 and gravity ball 5, wherein the middle part of hollow tube 6 is fixedly connected in support 3, and is used for bearing gravity ball 5. The inside of hollow tube 6 is provided with rope 15, and rope 15 is used for connecting gravity ball 5 and the inner top wall of hollow tube 6, so that gravity ball 5 is in a suspended state, which plays a role in increasing the gravity of the whole support 3, thereby playing a role in stability. The weight of gravity ball 5 can be selected according to actual conditions. Threaded column 16 is threadedly connected to the bottom of hollow tube 6 and is fixedly connected to the top of gravity ball 5, which is used for fixing gravity ball 5 on hollow tube 6 when gravity ball 5 is not used, to prevent shaking. One end of rope 15 is fixedly connected to the inner top wall of hollow tube 6, and the other end is fixedly connected to the top of threaded column 16, so that gravity ball 5 is connected to the middle part of support 3, to enhance the overall central gravity, thereby reducing the shaking amplitude of the detector when it is disturbed by the outside world, and improving the accuracy of detection.

[0036] The rotating plate 4 is rotatably connected to the outside of the support 3 through the connecting column 18, and is used to directly contact the ground. In combination with the conical column 17, the rotating plate 4 increases the contact area of the support 3 with the ground, thereby further improving the ability of the support 3 to prevent accidental tipping, and enabling the coal dust gas concentration detector of the coal conveying machine to work stably in a complex environment.

[0037] With reference to Figure 1 - Figure 3 The fixing mechanism includes the outer shell 10 fixedly connected to the inside of the mounting rod 2, the inner shell 8 fixedly connected to the inside of the outer shell 10, the latch 7 slidably connected to the inside of the inner shell 8, the spring 14 sleeved outside the latch 7, the locking assembly provided outside the latch 7, the insertion rod 11 slidably connected to the inside of the mounting rod 2, and the latch 7 inserted into the inside of the insertion rod 11. The fixing mechanism is used to ensure the stable connection of the detector main body 1 in the mounting rod 2 and facilitate disassembly and adjustment. The fixing mechanism includes the outer shell 10 fixedly connected to the inside of the mounting rod 2, which plays a role in protecting and supporting the internal components and improves the overall stability of the fixing mechanism.

[0038] The inner shell 8 is fixedly connected to the inside of the outer shell 10, and is used to provide a sliding space for the latch 7 and limit the movement range thereof, so as to ensure that the latch 7 can be smoothly inserted and separated. The latch 7 is slidably connected to the inside of the inner shell 8, and is used to be inserted into the insertion rod 11 to fix the detector main body 1. The spring 14 is sleeved outside the latch 7, and provides an elastic force, so that the latch 7 always remains inserted into the insertion rod 11 when not subjected to an external force, thereby ensuring the stable fixation of the detector main body 1.

[0039] The locking assembly is provided outside the latch 7, and is used to temporarily lock the latch 7 after being pulled out, so that the detector main body 1 can be conveniently operated when adjustment or disassembly is required without having to pull the latch 7 all the time.

[0040] With reference to Figure 2 and Figure 3The locking assembly includes a backing plate 13 and a clamping block 12. The backing plate 13 is fixedly connected to the outside of the bolt 7, and the clamping block 12 is fixedly connected to the outside of the backing plate 13. A U-shaped clamping groove 9 is formed on the outside of the inner shell 8, and the clamping block 12 is slidingly connected inside the U-shaped clamping groove 9. The clamping block 12 is slidingly connected inside the outer shell 10, and the backing plate 13 is slidingly connected inside the inner shell 8. One end of the spring 14 is fixedly connected to the top of the backing plate 13, and the other end of the spring 14 abuts against the inner wall of the inner shell 8. The backing plate 13 is used to fix the clamping block 12 and also to transmit the elastic force of the spring 14 to the bolt 7. The clamping block 12 cooperates with the U-shaped clamping groove 9. When the bolt 7 is pulled out, the clamping block 12 can be clamped into the U-shaped clamping groove 9 by rotating the bolt 7, thereby temporarily locking the bolt 7. When unlocking is needed, the bolt 7 can be rotated by slightly pulling it, and then the clamping block 12 can slide in the U-shaped clamping groove 9 by rotating the bolt 7 in the opposite direction, thereby unlocking the bolt 7.

[0041] Working principle: Before using the detector main body 1, first of all, the support 3 needs to be stably placed in a suitable position. Then, rotate each rotating plate 4 on the outside of the support 3, so that the conical column 17 is stably inserted into the ground, thereby enhancing the stability of the support 3. Next, unscrew the gravity ball 5, which will naturally hang in the middle of the support 3 under the traction of the rope 15, thereby increasing the central gravity of the support 3 and effectively preventing the equipment from toppling due to external forces, thereby improving overall stability.

[0042] Next, pull the bolt 7 out of the fixed position and rotate it so that the clamping block 12 is precisely inserted into the U-shaped clamping groove 9. At this time, the bolt 7 enters a temporary locking state without the need for continuous external force to maintain its position, making the installation process more convenient. Then, stably insert the insertion rod 11 on the outside of the detector main body 1 into the installation rod 2 to ensure correct docking of the equipment.

[0043] After completing the insertion of the insertion rod 11, slightly pull the bolt 7 so that it can rotate freely, and then rotate it in the opposite direction so that the clamping block 12 smoothly slides in the U-shaped clamping groove 9. Finally, release the bolt 7, which will automatically return to its original position under the elastic force of the spring 14, precisely inserting it into the insertion rod 11, thereby firmly fixing the detector main body 1 and completing the entire installation process.

[0044] When the detector is in operation, if the dust gas concentration detected exceeds the set threshold value, the alarm system on the equipment will immediately issue a warning signal to remind relevant personnel to take appropriate measures in a timely manner to ensure the safety and stability of the coal conveying environment.

[0045] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
