Description

Technical Field

[0001] This utility model relates to the field of physical sampling technology, specifically a power plant steam and water on-site sampler. Background Technology

[0002] The steam-water system in a power plant is a crucial link in the steam circulation and water quality monitoring process during thermal power generation. Its on-site sampling device is used to collect steam-water samples in real time to analyze water quality parameters, which is essential for ensuring the safe operation of the equipment. In existing technologies, steam-water sampling operations largely rely on manual intervention, especially in the collection bottle replacement process, where there is a significant drawback. Operators must manually switch collection locations, resulting in poor continuity and low efficiency in the sampling process, making it difficult to meet the continuous monitoring needs of power plants.

[0003] The existing soft drink sampler's collection mechanism design is relatively simple, and the fixing and removal of the collection bottle is not convenient enough. Although some structures can achieve basic sampling functions, changing the collection bottle requires disassembling complex fixing devices, resulting in time-consuming and laborious operations. At the same time, the connection and positioning accuracy between the collection bottle and the sampling pipeline is insufficient, and liquid samples are prone to leakage during sampling due to shaking or displacement, which affects sampling accuracy and increases the workload of on-site cleanup. In addition, the manual switching of the collection bottle operation mode makes it difficult to ensure the uniformity of the sampling interval, and it is not well adapted to scenarios requiring high-frequency, continuous sampling. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an on-site sampler for steam and water in power plants. This solves the problem of liquid sample leakage during sampling due to shaking or displacement, which affects sampling accuracy and increases on-site cleanup workload. Furthermore, manually switching the collection bottle operation mode makes it difficult to ensure uniformity of sampling intervals, resulting in poor adaptability to scenarios requiring high-frequency, continuous sampling.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power plant steam and water on-site sampler, comprising: a base, a turntable, a control valve, and a condenser tube. The turntable is mounted on the upper end of the base, which provides stable support for the entire sampler, ensuring that the turntable does not shift or shake during rotation, thus laying the foundation for the accuracy of subsequent sampling operations. The control valve is connected to the upper end of the turntable, and can precisely control the flow rate and on / off state of steam and water entering the collection mechanism. The valve is opened when sampling is required and closed after sampling is completed, avoiding steam and water waste or leakage.

[0006] The control valve is connected to the water outlet of the condenser. After the condenser cools the steam and water, the cooled steam and water is delivered to the control valve through the water outlet. The control valve then distributes the steam and water to the corresponding collection mechanism to achieve orderly sampling of the steam and water. The turntable is uniformly equipped with collection mechanisms. The uniformly equipped collection mechanisms can sample multiple portions of steam and water at the same time, improving sampling efficiency and ensuring the independence and consistency of each sample, thus avoiding cross-contamination.

[0007] The collection mechanism includes a fixing component connected to a turntable. The fixing component serves to connect and secure the collection mechanism, ensuring its stable installation inside the turntable and preventing it from falling off or shifting during turntable rotation. An elastic component is connected to the top of the fixing component. This elastic component has a certain elastic expansion and contraction capacity. When the collection bottle is placed on the support component, the elastic component can adapt to the weight of the collection bottle, providing cushioning and protection to prevent damage from impact forces during placement. A support component is connected to the top of the elastic component, directly contacting the collection bottle and providing a stable support platform to ensure the bottle remains upright during sampling, preventing spillage.

[0008] The top of the support is equipped with a collection bottle, which is the core container for carbonated beverage sampling. It is used to store carbonated beverage samples delivered from the limiting sleeve, so that the composition and parameters of the carbonated beverage can be detected and analyzed later. The inlet of the collection bottle is equipped with a limiting sleeve, which can limit and guide the path of carbonated beverage into the collection bottle, ensuring that the carbonated beverage flows into the collection bottle accurately, while preventing the carbonated beverage from splashing out during the flow process, thus ensuring the accuracy of the sample volume.

[0009] The limiting sleeve is connected to the top of the inner cavity of the turntable. Through this connection, the limiting sleeve can receive the carbonated beverage delivered from above and transfer it to the collection bottle, thus ensuring smooth delivery of the beverage. A geared motor is installed on the top of the base. This motor provides power for the rotation of the turntable and has a speed reduction function, allowing precise control of the turntable's rotation speed and angle. This ensures that the turntable can smoothly and orderly drive the collection mechanism to the designated sampling position. The output end of the geared motor is connected to the turntable. Through this direct connection, the power of the geared motor can be directly transmitted to the turntable, ensuring efficient and stable power transmission and guaranteeing that the turntable rotates according to preset requirements.

[0010] The condenser tube has an internal tube body, which serves as the main channel for the flow of steam and water within the condenser tube. This tube body provides cooling space, allowing the steam and water to fully exchange heat with the external cooling medium, thus achieving temperature reduction. An external spiral water pipe is installed around the tube body. This spiral structure significantly increases the contact area between the spiral water pipe and the tube body. When cooling water flows through the spiral water pipe, it can more efficiently absorb the heat from the steam and water within the tube body, improving the condensation and cooling effect and rapidly reducing the steam and water temperature. A spring is installed between the limiting sleeve and the spiral water pipe. The spring acts as an elastic buffer between the limiting sleeve and the spiral water pipe. When the turntable rotates or the equipment is subjected to slight vibration, the spring can offset part of the vibration impact force, preventing the connection between the limiting sleeve and the spiral water pipe from becoming loose or damaged, and ensuring the stability of the steam and water conveying channel. The left side of the pipe body is connected to a short pipe through a corrugated pipe. The corrugated pipe has good flexibility and extensibility. The connection between the corrugated pipe and the short pipe can adapt to possible installation deviations or slight displacements between the pipe body and the short pipe, while reducing the impact of vibration on the connection part, ensuring the sealing and smoothness of the steam and water conveying, and preventing steam and water leakage.

[0011] Preferably, the turntable has a top plate, and assembly arms are evenly distributed around its exterior. A water inlet is located on the top of the turntable and is connected to a limiting sleeve. The top plate protects the components on the top of the turntable, preventing external dust and impurities from falling in and affecting the sampling purity.

[0012] The assembly arm can be used to install additional auxiliary components or marking structures to facilitate operator identification and operation; the connection design between the inlet and the limiting sleeve ensures that the water sample passes smoothly from the condenser tube through the control valve, through the inlet and the limiting sleeve into the collection bottle, ensuring a smooth sampling path.

[0013] The condenser tube has an internal tube body, and the tube body is externally fitted with a spiral water pipe. The tube body is used to transport the vapor-water sample to be collected. The spiral water pipe allows for heat exchange between the vapor-water sample and the tube body through flowing cooling water. The spiral structure increases the cooling area and cooling time, efficiently condensing the vapor-water sample into a liquid state, which facilitates subsequent sampling and testing.

[0014] The base has an annular guide groove at its top, and a guide block is slidably connected to the inner cavity of the annular guide groove. The guide block is connected to the turntable, and a bracket connects the geared motor to the base. The cooperation between the annular guide groove and the guide block guides and limits the rotation of the turntable, preventing it from shifting or wobbling during rotation and ensuring the smoothness and accuracy of the turntable's rotation. The bracket provides stable support for the geared motor, ensuring its stability during operation and preventing motor vibration from affecting the overall operation of the equipment.

[0015] Preferably, a control module is externally mounted on the control valve, and a sealing ring is provided between the control valve and the condenser pipe. The control module can automatically or remotely control the on / off state of the control valve, improving the convenience and accuracy of operation; the sealing ring enhances the sealing performance at the connection between the control valve and the condenser pipe, preventing leakage of steam and water during transportation and ensuring the accuracy of the sampling amount and the purity of the sample.

[0016] Preferably, the elastic element is a compression spring, and both ends of the compression spring are welded and fixed to the fixing element and the support element, respectively. As an elastic element, the compression spring has good elastic recovery performance and can continuously provide upward elastic force to the support element, ensuring that the collection bottle and the limiting sleeve are in close contact; the welding and fixing method at both ends can ensure the firmness of the connection between the elastic element and the fixing element and the support element, and prevent loosening or falling off during long-term use.

[0017] Preferably, the support member has an internal threaded groove at its top and the collection bottle has an external thread at its bottom, and the collection bottle and the support member are connected by threads. The threaded connection makes the installation and disassembly of the collection bottle and the support member more convenient and quick, allowing operators to replace the collection bottle for sampling or clean and disinfect it in a timely manner. At the same time, the threaded connection has good sealing and stability, which can prevent the collection bottle from tipping over or leaking during the sampling process.

[0018] Preferably, the limiting sleeve is made of silicone material, and the inner wall of the limiting sleeve is provided with annular protrusions, which are interference-fitted with the water inlet of the collection bottle. Silicone material has good elasticity and sealing properties, and can adapt to slight dimensional changes in the water inlet of the collection bottle; the interference fit between the annular protrusions and the water inlet of the collection bottle further enhances the sealing effect between the two, effectively preventing sample leakage during sampling and ensuring sampling accuracy.

[0019] Preferably, the geared motor is fitted with a protective shell, which is bolted to the base. The surface of the protective shell has ventilation holes. The protective shell effectively prevents external dust and moisture from corroding the geared motor, protecting internal components and extending its service life. The bolted connection facilitates the installation and removal of the protective shell, making motor inspection and maintenance convenient. The ventilation holes dissipate heat generated during motor operation, preventing overheating from affecting normal operation.

[0020] Preferably, the tube body is made of stainless steel, and a spiral guide plate is provided inside the tube body. Stainless steel has good corrosion resistance and high temperature resistance, making it suitable for use in complex environments for steam and water sampling and extending the service life of the tube body. The spiral guide plate can change the flow path of steam and water in the tube body, prolong the residence time of steam and water in the tube, and allow steam and water to have more complete heat exchange with the spiral water pipe outside the tube body, thereby improving the condensation effect.

[0021] Compared with the prior art, this utility model provides an on-site sampler for steam and water in power plants, which has the following advantages:

[0022] This on-site steam and water sampler for power plants utilizes a geared motor to drive a turntable, which in turn rotates a fixed component connected to the turntable, thus driving the entire collection mechanism. When the collection bottle rotates to the bottom position of the limiting sleeve, an elastic element drives the support component and the top collection bottle to rise, achieving precise engagement between the collection bottle and the limiting sleeve. This ensures the stability of fluid delivery during sampling and effectively prevents fluid leakage from affecting sampling accuracy. Simultaneously, during the engagement process, the rising motion of the collection bottle impacts the slidingly connected tube inside the limiting sleeve. This impact generates momentum for the fluid inside the tube, accelerating its flow and improving the efficiency of fluid discharge, reducing fluid residue inside the tube, and ensuring the accuracy of the sample volume.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides a technical solution, please refer to Figure 1 and Figure 2 A power plant steam and water on-site sampler includes: a base 1, a turntable 2, a control valve 4, and a condenser tube 5. The turntable 2 is mounted on the upper end of the base 1. The control valve 4 is connected to the upper end of the turntable 2 and is connected to the water outlet end of the condenser tube 5. A collection mechanism 3 is evenly arranged inside the turntable 2. The collection mechanism 3 includes a fixing member 31. A spring is provided on the outside of the condenser tube 5. The other end of the spring is connected to the connection end of the condenser tube 5. The condenser tube 5 can move. When the condenser tube 5 is displaced, it can be returned to its original position by the spring.

[0031] The fixing member 31 is connected to the turntable 2. The top of the fixing member 31 is connected to the elastic member 32. The top of the elastic member 32 is connected to the support member 33. The top of the support member 33 is provided with a collection bottle 34. The inlet of the collection bottle 34 is fitted with a limiting sleeve 35. The limiting sleeve 35 is connected to the top of the inner cavity of the turntable 2. The top of the base 1 is provided with a reduction motor 13. The inlet of the collection bottle 34 is designed with rounded corners. As the collection bottle 34 rotates to the bottom of the limiting sleeve 35, it will be driven down by the outside of the limiting sleeve 35. When it rises to the inside of the limiting sleeve 35, it will also be driven down by the inside of the limiting sleeve 35 when it rotates, thus ensuring normal movement.

[0032] Please see Figure 3 , Figure 4 and Figure 5 The output end of the geared motor 13 is connected to the turntable 2. When the geared motor 13 is working, it can drive the turntable 2 to rotate smoothly, thereby realizing the sequential switching of multiple collection bottles 34, meeting the needs of continuous multiple sampling, and improving sampling efficiency; the elastic element 32 can provide a buffer for the collection bottle 34 through its own elastic deformation, ensuring that the water inlet of the collection bottle 34 and the limiting sleeve 35 are always tightly fitted, avoiding leakage during the sampling process; the cooperation of the various components of the collection mechanism 3 can stably support the collection bottle 34, ensuring the stability of the sampling process.

[0033] The turntable 2 has a top plate 21 on its top, and assembly arms 22 are evenly distributed on its exterior. A water inlet is located on the top of the turntable 2 and is connected to a limiting sleeve 35. The top plate 21 protects the components on the top of the turntable 2, preventing external dust and impurities from falling in and affecting the sampling purity. An annular groove is formed at the bottom of the top plate 21, and the interior of the annular groove can slide to connect with the water inlet of the collection bottle 34, thereby ensuring the stability of the collection bottle 34 during movement.

[0034] The assembly arm 22 can be used to install additional auxiliary components or marking structures to facilitate operator identification and operation; the connection design between the water inlet and the limiting sleeve 35 ensures that the water sample can smoothly enter the collection bottle 34 from the condenser tube 5 through the control valve 4, passing through the water inlet and the limiting sleeve 35, thus ensuring a smooth sampling path.

[0035] The condenser tube 5 has a tube body 51 inside, and a spiral water pipe 52 is installed outside the tube body 51. The tube body 51 is used to transport the steam and water to be sampled. The spiral water pipe 52 can exchange heat with the steam and water inside the tube body 51 through the flowing cooling water. The spiral structure increases the cooling area and cooling time, which can efficiently condense the steam and water into a liquid state, which is convenient for subsequent sampling and testing.

[0036] The top of the base 1 is provided with an annular guide groove 11, and a guide block 12 is slidably connected to the inner cavity of the annular guide groove 11. The guide block 12 is connected to the turntable 2, and a bracket is connected between the geared motor 13 and the base 1. The cooperation between the annular guide groove 11 and the guide block 12 can guide and limit the rotation of the turntable 2, preventing the turntable 2 from deviating or shaking during rotation, and ensuring the smoothness and accuracy of the rotation of the turntable 2. The bracket can stably support the geared motor 13, ensuring its stability during operation and avoiding the impact of motor vibration on the operation of the overall equipment.

[0037] A control module is externally mounted on the control valve 4, and a sealing ring is installed between the control valve 4 and the condenser pipe 5. The control module can automatically or remotely control the on / off state of the control valve 4, improving the convenience and accuracy of operation; the sealing ring enhances the sealing performance at the connection between the control valve 4 and the condenser pipe 5, preventing leakage of steam and water during transportation and ensuring the accuracy of the sampling amount and the purity of the sample.

[0038] The elastic element 32 is a compression spring, and its two ends are welded and fixed to the fixing element 31 and the support element 33, respectively. As the elastic element 32, the compression spring has good elastic recovery performance and can continuously provide upward elastic force to the support element 33, ensuring that the collection bottle 34 is in close contact with the limiting sleeve 35; the welding and fixing method at both ends can ensure the firmness of the connection between the elastic element 32 and the fixing element 31 and the support element 33, and prevent loosening or falling off during long-term use.

[0039] The support member 33 has an internal threaded groove at its top, and the collection bottle 34 has an external thread at its bottom. The collection bottle 34 and the support member 33 are connected by threads. The threaded connection makes the installation and removal of the collection bottle 34 and the support member 33 more convenient and quick, allowing operators to replace the collection bottle 34 for sampling or to clean and disinfect it in a timely manner. At the same time, the threaded connection has good sealing and stability, preventing the collection bottle 34 from tipping over or leaking during the sampling process.

[0040] The limiting sleeve 35 is made of silicone, and its inner wall has an annular protrusion that is interference-fitted with the inlet of the collection bottle 34. The silicone material has good elasticity and sealing properties, allowing it to adapt to slight dimensional changes in the inlet of the collection bottle 34. The interference fit between the annular protrusion and the inlet further enhances the sealing effect, effectively preventing sample leakage during sampling and ensuring sampling accuracy.

[0041] The geared motor 13 is fitted with a protective shell, which is bolted to the base 1. The protective shell has ventilation holes on its surface. The protective shell effectively prevents external dust and moisture from corroding the geared motor 13, protecting the internal components and extending the motor's service life. The bolted connection facilitates the installation and removal of the protective shell, making it convenient for motor inspection and maintenance. The ventilation holes dissipate the heat generated during motor operation, preventing overheating and ensuring normal operation.

[0042] The tube body 51 is made of stainless steel and has a spiral guide plate inside. Stainless steel has good corrosion resistance and high temperature resistance, making it suitable for use in complex environments for steam and water sampling and extending the service life of the tube body 51. The spiral guide plate can change the flow path of steam and water in the tube body 51, prolong the residence time of steam and water in the tube, and allow steam and water to have more complete heat exchange with the spiral water pipe 52 outside the tube body 51, thereby improving the condensation effect.

[0043] This scheme first connects the condenser tube 5 to the outlet of the steam pipeline in the power plant. When steam water needs to be sampled for testing, the valve of the steam pipeline is opened. At this time, the steam enters the interior of the condenser tube 5 and is cooled into liquid by the condenser tube 5. The liquid sample enters the interior of the collection bottle 34 through the control valve 4 and the limiting sleeve 35 for sampling. When one collection bottle 34 has been collected, the reduction motor 13 is started to drive the turntable 2 to rotate, and the control valve 4 is closed. The other set of collection bottles 34 is rotated to the bottom of the control valve 4, which will collide with the control valve 4, thereby causing the control valve 4 and the condenser tube 5 to vibrate, increasing the flow rate of the sample and preventing the sample from being stuck inside the condenser tube 5. The collection bottle 34 with the collected sample is pressed down to make it detach from the limiting sleeve 35, and then the collection bottle 34 is taken out, completing the sample collection.

[0044] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
