Description

Technical Field

[0001] This utility model relates to the field of water vapor sampling, specifically a multi-purpose sampling and analysis device. Background Technology

[0002] In the thermal power generation system, the quality of water and steam directly affects the performance of the heat engine. Therefore, it is necessary to continuously sample and analyze the water online to ensure the quality of water and steam, prevent corrosion and scaling of thermal equipment such as boilers, steam drums, and heat engines, and ensure the safe and economical operation of the system. Water and steam sampling devices are usually used for sampling. If the water sample under high temperature and high pressure is directly introduced into the analysis and detection instruments, the instrument panel will be severely damaged. Therefore, the water and steam sampling device is equipped with a pre-cooling device to lower the temperature of the water sample, and then the internal constant temperature cooling device lowers the temperature to the required temperature.

[0003] Traditional water vapor sampling devices are typically fixed to the ground, resulting in significant waste of manpower and resources each time they are moved, thus affecting the efficiency of relocation. Therefore, a new technical solution is needed to address this issue. Utility Model Content

Two sets of connecting frames are fixedly connected to the outside of two sets of connecting shafts respectively. The inner sides of each set of connecting frames are rotatably connected to a rotating shaft via bearings. A movable roller is fixedly connected to the outside of the rotating shaft.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1: A multi-purpose sampling and analysis device, see [link to example]. Figures 1 to 3 ,include: The sampling analyzer body 1 is used for water vapor sampling and analysis. The sampling analyzer body 1 includes a water vapor sampling module and an analysis and detection module. The sampling probe is inserted into the water vapor source (such as a pipe or atmospheric environment). The negative pressure pump is started to form an airflow channel. Water vapor enters the sampling chamber under the action of pressure difference. The water vapor entering the sampling chamber is condensed (if necessary) to remove excess moisture, or the moisture in the water vapor is adsorbed by the drying tube (depending on the detection requirements). Then, the flow controller is adjusted to a constant flow rate to ensure that the analysis module receives a stable sample flow rate. Then, the pre-treated water vapor enters the analysis module. Each sensor outputs an electrical signal according to the detection principle. After signal amplification and filtering, the microprocessor (MCU) performs data calculation and calibration. The analysis results are displayed in real time on the display screen and can be stored in the device memory or uploaded to the cloud (if a communication module is provided). The user can set the detection threshold through the operation interface. When the water vapor composition exceeds the preset range, the device will automatically alarm. A moving mechanism is provided at the bottom of the sampling analyzer body 1 to enable the moving of the sampling analyzer body 1; The moving mechanism includes: Two sets of connecting blocks 2 are fixedly connected to the bottom sides of the sampling analyzer body 1. Each set of connecting blocks 2 is rotatably connected to a connecting shaft 21 through a bearing. A worm gear 22 is fixedly connected to the outer side of the middle part of the connecting shaft 21. Two sets of connecting frames 26 are fixedly connected to the outer sides of two sets of connecting shafts 21 respectively. A rotating shaft 28 is rotatably connected between the inner sides of each set of connecting frames 26 through a bearing. A movable roller 27 is fixedly connected to the outer side of the rotating shaft 28. A drive assembly, disposed between the two worm gears 22, is used to drive the moving roller 27 to rotate and adjust the movement state of the sampling analyzer body 1.

[0016] During operation, a moving mechanism is installed at the bottom of the sampling analyzer body 1. The drive component drives the worm gear 23 to rotate, which in turn drives the worm wheel 22 and the connecting shaft 21 to rotate. This causes the moving roller 27 to rotate and contact the ground, and together with the connecting frame 26, lifts the sampling analyzer body 1. The rotation of the moving roller 27 facilitates the movement of the sampling analyzer body 1, thus changing the drawback of traditional devices that rely on manual handling. No additional hoisting equipment or multiple people are needed, which significantly reduces the manpower input during the movement process, avoids the risk of equipment collisions that may occur due to manual handling, and greatly improves the efficiency of device movement. This allows water vapor sampling operations to be carried out more flexibly in different areas.

[0017] For details, see Figure 1 It also includes a support mechanism, which includes connecting cylinders 3 fixedly connected to the four corners of the bottom of the sampling analyzer body 1. Each of the four connecting cylinders 3 has a support column 31 at its bottom. The length of the connection between the connecting cylinder 3 and the support column 31 is greater than the height of the connecting block 2. When the sampling analyzer body 1 is in use, the driving component drives the moving roller 27 to be placed horizontally and detached from the support surface, so that the support column 31 contacts the support surface, thereby forming a stable four-point support structure for the sampling analyzer body 1, improving the stability of the equipment during sampling analysis, ensuring the accuracy of the analysis data, and solving the problem of equipment shaking caused by the moving roller 27 supporting the sampling analyzer body 1.

[0018] Further, see Figure 1 The support column 31 is threadedly connected inside the connecting cylinder 3. A shock-absorbing pad 32 is fixedly connected to the end of the support column 31 away from the connecting cylinder 3. The shock-absorbing pad 32 is a rubber pad. Through the threaded connection design between the support column 31 and the connecting cylinder 3, the extension length can be adjusted by rotating the support column 31 to adapt to the support requirements of different ground flatness. This structure can not only ensure the stable support of the equipment on flat ground, but also compensate for the unevenness of the ground by adjusting the height of the support column 31, avoiding the tilting of the equipment due to uneven ground, improving the adaptability of the equipment in different working environments, and enhancing the ease of use. When the moving roller 27 rotates and disengages from the support surface, the shock-absorbing pad 32 contacts the support surface, thereby buffering the vibration generated by the descent of the sampling analyzer body 1 and its contact with the support surface. This avoids the vibration caused by the support column 31 directly contacting the support surface rigidly, which could damage the sampling analyzer body 1. It can also absorb the vibration generated by the sampling analyzer body 1 during operation, reducing the vibration of the sampling analyzer body 1 during operation, further improving the stability of the sampling analyzer body 1, and ensuring the accuracy of the analysis data.

[0019] It is worth noting that, see Figure 2 The drive assembly includes fixed plates 24 fixedly connected to both sides of the bottom of the sampling analyzer body 1. A worm gear 23 is rotatably connected between the two fixed plates 24 via bearings, and the worm gear 23 meshes with two worm wheels 22. A drive motor 25 is fixedly connected to the outer side of one of the fixed plates 24, and the drive end of the drive motor 25 is connected to the worm gear 23 via a coupling. By driving the worm gear 23 to rotate through the drive motor 25, the rotation of the two moving rollers 27 can be synchronously controlled, thereby improving the stability of the sampling analyzer body 1 when the moving rollers 27 contact the support surface and lift it up. Furthermore, since the lead angle (i.e., the helix angle) of the worm gear 23 is less than or equal to the equivalent friction angle of the worm wheel 22 and worm gear 23 pair materials, the position can be automatically locked when the adjustment of the moving rollers 27 is stopped, preventing the weight of the sampling analyzer body 1 from causing the moving rollers 27 to reset and affecting the movement of the sampling analyzer body 1.

[0020] It is worth noting that, see Figure 1 A nut 33 is fixedly connected to the outside of the support column 31 above the shock-absorbing pad 32. The nut 33 allows personnel to rotate the support column 31 with a wrench, thereby facilitating the adjustment of the length of the connection between the connecting cylinder 3 and the support column 31.

[0021] It is worth mentioning that, see Figure 2 and Figure 3 A fixing bolt 5 is rotatably passed through one end of the outer side of the connecting frame 26. The fixing bolt 5 is threadedly connected to the connecting frame 26 and contacts the end face of the moving roller 27. The fixing bolt 5 on the outer side of the connecting frame 26 is threadedly connected through the connecting frame 26 and contacts the end face of the moving roller 27 to form an adjustable mechanical locking structure. When the equipment needs to be stopped during the movement process, the moving roller 27 is limited to prevent the equipment from being displaced due to ground tilt or external force collision, which could cause damage.

[0022] It is worth mentioning that, see Figure 1 The sampling analyzer body 1 is fixedly connected to both ends of a handle 4, and the handle 4 is symmetrically distributed on both sides of the sampling analyzer body 1. The handle 4 symmetrically arranged at both ends of the sampling analyzer body 1 provides convenient force points for the operator, making it easy for the operator to push and move the sampling analyzer body 1.
