Description

Technical Field

[0001] The invention relates to the technical field of water network monitoring, and in particular to a water network monitoring device for a thermal power plant. Background Art

[0002] Thermal power plants are the largest water-consuming industry in my country. At this stage, the country has begun to advocate water conservation and effective protection of water resources, and thermal power plants have begun to carry out relevant work on water conservation. The development of water conservation has enabled thermal power plants to achieve good industrial efficiency, and the power and water consumption of thermal power plants has gradually decreased. At present, thermal power plants mainly use human resources to test cooling water and sewage. This detection method will not only increase a lot of manpower workload, but also affect the accuracy of regulation, and ultimately lead to the feed water and sewage being unable to meet the basic rate control requirements of concentration. Therefore, it is necessary to strengthen the water management of thermal power plants, adopt the latest water resource treatment technology, and truly implement the important goals of saving water and protecting the environment.

[0003] However, there are usually some problems in the daily use of ordinary thermal power plant water network monitoring devices. With the development of science and technology, technical personnel in related fields have also carried out a lot of optimization on the thermal power plant water network monitoring devices. In order to make a more accurate comparison, a Chinese patent with publication number CN205773780U discloses a circulating cooling water dosing treatment system for a thermal power plant, including a dosing control device and a first dosing execution device, and also includes a pH value detection device, a residual chlorine detection device, an ORP measurement device, a conductivity measurement device and a dissolved oxygen measurement device electrically connected to the dosing control device; the signal acquisition ends of the pH value detection device, the residual chlorine detection device, the ORP measurement device, the conductivity measurement device and the dissolved oxygen measurement device are all located in the circulating water pool of the thermal power plant; the first dosing execution device is electrically connected to the dosing control device, and the output end of the first dosing execution device is connected to the circulating water pool of the thermal power plant via a first dosing pump. The above-mentioned prior art collects relevant data through the online monitoring function, and then feeds back the measurement signal to the dosing system to achieve automatic adjustment of concentration and dosage to complete the dosing, thereby reducing the workload and achieving the purpose of online dosing treatment of circulating cooling water in thermal power plants.

[0004] However, the above-mentioned circulating cooling water dosing treatment system of thermal power plants still has some shortcomings in actual use:

[0005] 1. The above-mentioned dosing treatment system for circulating cooling water in a thermal power plant collects relevant data through an online monitoring function, and then feeds back the measurement signal to the dosing system to achieve automatic adjustment of concentration and dosage and complete dosing, thus reducing the workload. To collect relevant data through online monitoring, various sensors need to be placed in various places of the water network. If a sensor is damaged, operators still need to reach the corresponding place for repair and replacement, thus increasing the workload.

[0006] 2. The above-mentioned dosing treatment system for circulating cooling water in a thermal power plant doses through a dosing actuator, with real-time monitoring and real-time control, faster response, and low labor cost; however, the dosing actuator cannot perform precise dosing ratio, which may cause under-dosing or over-dosing, and further damage the water network.

[0035] The following combines the attached Figures 1 to 10 The embodiments of the present invention will be described in detail below, but the present invention can be implemented in many different ways defined and covered by the claims.

[0036] An embodiment of the present application discloses a water network monitoring device for a thermal power plant. It should be noted that this application is mainly applied in the process of monitoring the water network of a thermal power plant. In terms of technical effects, it can intermittently extract the water in the water network and send the extracted water for detection, so as to realize the monitoring of the water network of the thermal power plant and facilitate the centralized maintenance of sensors by operators; especially when the water in the water network has problems and needs to be mixed with chemicals, by mixing the extracted and tested water with the chemicals and transmitting them into the water network, automatic chemical dosing and mixing of the water network are realized, reducing the operation steps of operators and preventing the outside water from affecting the water network; further, when dosing and mixing in this application, the chemicals and water are proportioned in a certain ratio to prevent over-dosing or under-dosing of chemicals during dosing and mixing, which may cause further damage to the water network.

[0037] Embodiment 1:

[0038] Reference Figure 1 As shown, a water network monitoring device for a thermal power plant comprises a water network pipeline 1, on which a sealing ring 10 is sleeved, and the sealing ring 10 is used to prevent water leakage in the water network during sampling and drug addition; a sampling mechanism 2 is arranged on the top of the sealing ring 10, and the sampling mechanism 2 is used to intermittently extract water in the water network pipeline 1 and send the extracted water for detection, thereby realizing the monitoring of the water network of the thermal power plant and facilitating the operator to perform centralized maintenance of the sensor; a drug adding mechanism 3 is arranged below the sealing ring 10, and the drug adding mechanism 3 is used to make the drug and the water to be tested be proportioned in a certain proportion during drug addition and blending, so as to prevent further damage to the water network caused by adding too much or too little drug during drug addition and blending; a detection shell 11 is arranged between the sampling mechanism 2 and the drug adding mechanism 3, and the detection shell 11 and the drug adding mechanism 3 are connected by a connecting pipe 12, so that the water extracted by the drug taking mechanism can enter the detection shell 11, and the water in the detection shell 11 can enter the drug adding mechanism 3 through the connecting pipe 12.

[0039] In the specific implementation process, the water in the water network pipeline 1 is intermittently extracted through the sampling mechanism 2 and the extracted water is sent to the detection shell 11, so as to realize the monitoring of the water network of the thermal power plant and facilitate the operator to centrally maintain the sensor. Then the water in the detection shell 11 enters the dosing mechanism 3 through the connecting pipe 12. When there is a problem with the water in the water network pipeline 1 and it needs to be added with medicine for blending, the dosing mechanism 3 is used to make the medicine and the water for inspection be mixed in a certain proportion to prevent the water network from being further damaged by adding too much or too little medicine during the dosing and blending.

[0040] Reference Figure 2 and Figure 3As shown, it is the sampling mechanism 2 in the present application; specifically, the sampling mechanism 2 includes a sampling short tube 20, a sampling long tube 201, a first blocking plate 21, a moving ring 22, a C-shaped plate 23, a guide rod 24, a second blocking plate 25, a sampling chamber 26, a transmission chamber 27, a first spring 28, and a driving unit 29. A sampling short tube 20 is provided at the top of the sealing ring 10, and the water in the water network pipeline 1 can enter the sampling short tube 20; a connection is made between the sampling short tube 20 and the top of the detection housing 11 through the sampling long tube 201, and the sampling long tube 201 is sleeved on the sampling short tube 20. The water in the sampling short tube 20 can enter the sampling long tube 201, and the water in the sampling long tube 201 can enter the detection housing 11; a first blocking plate 21 located inside the sampling long tube 201 is hinged at the top of the sampling short tube 20, and the first blocking plate 21 is used to prevent the water in the sampling long tube 201 from flowing into the sampling short tube 20; a moving ring 22 is slidably provided inside the sampling long tube 201, and the moving ring 22 can slide under the restriction of the sampling long tube 201; a C-shaped plate 23 is provided at the bottom of the moving ring 22, and a guide rod 24 is slidably provided inside the C-shaped plate 23, and the guide rod 24 can slide under the restriction of the C-shaped plate 23; a second blocking plate 25 is provided at the top of the guide rod 24, and the second blocking plate 25 can move together with the guide rod 24 when the guide rod 24 moves; the space inside the sampling long tube 201 between the first blocking plate 21 and the second blocking plate 25 is the sampling chamber 26, the space inside the sampling long tube 201 between the second blocking plate 25 and the detection housing 11 is the transmission chamber 27, and a first spring 28 sleeved on the guide rod 24 is provided between the second blocking plate 25 and the C-shaped plate 23, and the first spring 28 can always provide an upward thrust to the second blocking plate 25; a driving unit 29 is further provided at the bottom of the moving ring 22, and the driving unit 29 is used to drive the moving ring 22 to reciprocally slide under the restriction of the sampling long tube 201.

[0041] In a specific implementation process, when the driving unit 29 drives the moving ring 22 to slide downward under the restriction of the sampling long tube 201, the space of the sampling chamber 26 becomes larger, resulting in a decrease in the pressure inside the sampling chamber 26. The first blocking plate 21 rotates under the action of the pressure in the water network pipeline 1, so that the water in the water network pipeline 1 enters the sampling chamber 26 through the sampling short tube 20; then the driving unit 29 drives the moving ring 22 to slide upward, making the space of the sampling chamber 26 smaller and the pressure larger, forcing the water in the sampling chamber 26 to overcome the pressure of the first spring 28 and push the second blocking plate 25 to move downward under the restriction of the guide rod 24. Furthermore, the water in the sampling chamber 26 enters the transmission chamber 27, and the water in the transmission chamber 27 can flow into the detection housing 11. During this process, due to the increase in the pressure inside the sampling chamber 26, the first blocking plate 21 rotates, and the water in the sampling chamber 26 cannot enter the sampling short tube 20, realizing the intermittent extraction of the water in the water network pipeline 1 and sending the extracted water for detection, thereby realizing the monitoring of the water network in a thermal power plant and facilitating the centralized maintenance of the sensors by the operator.

The fixed rods 290 are symmetrically arranged at the bottom of the moving ring 22. When the fixed rods 290 move, the moving ring 22 can be driven to move together; the fixed rods 290 are connected by a T-shaped plate 291, and when the T-shaped plate 291 moves, the fixed rods 290 can be driven to move together; a mounting shell 292 is arranged on the side of the sampling long tube 201 away from the sealing ring 10, and a reciprocating screw rod 293 is rotatably arranged in the mounting shell 292, and the other side of the T-shaped plate 291 is sleeved on the reciprocating screw rod 293, and when the reciprocating screw rod 293 rotates, it can drive the T-shaped plate 291 to reciprocate up and down; a driving motor 294 is arranged between the reciprocating screw rod 293 and the detection shell 11 through the motor housing, and when the driving motor 294 rotates, it can drive the reciprocating screw rod 293 to rotate together.

[0043] In the specific implementation process, when the driving motor 294 rotates, it can drive the reciprocating screw 293 to rotate together. When the reciprocating screw 293 rotates, it can drive the T-shaped plate 291 to move back and forth up and down under the restriction of the reciprocating screw 293. When the T-shaped plate 291 moves, it can drive the fixed rod 290 to move together. When the fixed rod 290 moves, it can drive the moving ring 22 to move together, thereby driving the moving ring 22 to slide back and forth under the restriction of the sampling long tube 201.

[0047] In the specific implementation process, the water sent for inspection at the top of the connecting plate 32 can flow into the water storage chamber 3401 through the water inlet hole 33. When the water sent for inspection enters the water storage chamber 3401, it can flow to the bottom of the floating plate 3402 through the connecting hole 3403. Then the floating plate 3402 moves with the water level in the water storage chamber 3401. During this process, the floating plate 3402 can always remain level through the balancing ball 3404.

[0055] Embodiment three:

[0056] Reference Fig. 9 and Fig.10As shown, on the basis of the first and second embodiments, in order to more accurately discharge a certain amount of medicine from the medicine outlet slot 3412 and realize the accurate ratio of medicine and water, in the specific embodiment of the present scheme, a medicine discharging mechanism 6 is provided in the medicine storage chamber 3411; specifically, the medicine discharging mechanism 6 includes a baffle 60, a guide bevel block 61, an obstruction plate 62, a sliding groove 63, a second spring 64, a rack 1 65, an incomplete gear 66, a second rack 67, a pressure plate 68 and a third spring 69, and a portion of the L-shaped partition 3400 is provided at the bottom thereof, which is located away from the bar 3414 on the telescopic plate 3414. The baffle 60 on one side of the partition 3410, the top of the inner wall of the medicine adding shell 30 is provided with a guide inclined block 61 located on the side of the medicine adding inclined plate 3415 away from the strip partition 3410, the space formed between the guide inclined block 61, the L-shaped partition 3400 and the medicine adding shell 30 is used to store medicine, and the medicine on the top of the guide inclined block 61 is driven to move along the inclined edge of the guide inclined block 61 by the guide inclined block 61; the baffle 60 is slidably provided with an obstruction plate 62 cooperating with the guide oblique block 61, and the obstruction plate 62 is used to prevent the medicine from flowing out of the gap between the baffle 60 and the guide oblique block 61; the baffle A sliding groove 63 is provided in 60 for the blocking plate 62 to slide, and a plurality of springs 64 are provided between the sliding groove 63 and the blocking plate 62. The springs 64 can always provide a downward thrust for the blocking plate 62. A rack 65 penetrating the bottom of the dosing shell 30 is symmetrically provided at the bottom of the dosing inclined plate 3415. When the dosing inclined plate 3415 moves, the rack 65 can be driven to move together. An incomplete gear 66 cooperating with the rack 65 is rotatably provided at the bottom of the dosing shell 30. When the rack 65 moves, the incomplete gear 66 can be driven to rotate. The incomplete gear 66 cooperates with the rack 2 67, and the rack 2 67 penetrates the guide bevel 61 and the bottom of the dosing shell 30 and extends downward. When the incomplete gear 66 rotates, it can drive the rack 2 67 to move in the opposite direction of the moving direction of the rack 1 65; a pressure plate 68 is slidingly arranged above the guide bevel 61, and the pressure plate 68 is used to drive the medicine above the guide bevel 61 to flow out of the gap between the baffle 60 and the guide bevel 61 in a quantitative manner; the pressure plate 68 and the L-shaped partition 3400 are connected by a spring 3 69, and the spring 3 69 can always provide a downward thrust for the pressure plate 68.

[0057] In the specific implementation process, when the dosing inclined plate 3415 moves downward, it can drive the rack 1 65 to move together. When the rack 1 65 moves, it can drive the incomplete gear 66 to rotate. When the incomplete gear 66 rotates, it can drive the rack 2 67 to move upward. When the rack 2 67 moves, it can make the obstruction plate 62 overcome the thrust of the spring 2 64 and move upward, so that the obstruction plate 62 no longer hinders the drug from flowing out from the gap between the baffle 60 and the guide bevel block 61. Then, the pressure plate 68 drives the drug above the guide bevel block 61 to move quantitatively from the gap between the baffle 60 and the guide bevel block 61 to the top of the dosing inclined plate 3415, so as to more accurately discharge a certain amount of drug from the drug outlet groove 3412 and achieve a precise ratio of drug and water.

[0058] When working: the first step, when the driving motor 294 rotates, it can drive the reciprocating screw 293 to rotate together. When the reciprocating screw 293 rotates, it can drive the T-shaped plate 291 to move up and down under the restriction of the reciprocating screw 293. When the T-shaped plate 291 moves, it can drive the fixed rod 290 to move together. When the fixed rod 290 moves, it can drive the moving ring 22 to move together. When the moving ring 22 slides downward under the restriction of the sampling long tube 201, the space of the sampling chamber 26 becomes larger, resulting in a decrease in the pressure in the sampling chamber 26. The blocking plate 1 21 rotates under the action of the pressure in the water network pipe 1, so that the water in the water network pipe 1 enters the sampling chamber 26 through the sampling short tube 20; then the moving ring 22 slides upward, so that the space of the sampling chamber 26 becomes smaller and the pressure becomes larger, forcing the water in the sampling chamber 26 to overcome the pressure of the spring 1 28 and push the blocking plate 2 25 on the guide rod 24. , so that the water in the sampling chamber 26 enters the transmission chamber 27, and the water in the transmission chamber 27 can flow into the detection shell 11. In this process, the pressure in the sampling chamber 26 increases, causing the blocking plate 21 to rotate, and the water in the sampling chamber 26 cannot enter the sampling short tube 20. When the water in the transmission chamber 27 flows into the detection shell 11, the conductivity of the water in the water network pipe 1 is detected by the conductivity detector 5, the temperature of the water in the water network pipe 1 is detected by the water temperature sensor 50, and various impurities in the water in the water network pipe 1 are detected by the water quality sensor 51. Then, the detection results are displayed on the display screen, which is convenient for operators to better monitor the water network, realize intermittent extraction of water in the water network pipe 1 and send the extracted water for detection, thereby realizing the monitoring of the water network of the thermal power plant and facilitating the operators to centrally maintain the sensors.

[0059] Step 2: After the water to be inspected in the detection shell 11 is inspected, it enters the top of the inclined partition 31 in the dosing shell 30 through the connecting pipe 12. The water to be inspected is stored in the space formed by the top of the inclined partition 31, the top of the connecting plate 32 and the dosing shell 30, and the water to be inspected is concentrated on the top of the connecting plate 32 through the inclined partition 31. The water to be inspected on the top of the connecting plate 32 flows into the water storage chamber 3401 through the water inlet hole 33. When the water to be inspected enters the water storage chamber 3401, it can flow under the floating plate 3402 through the connecting hole 3403, and then the floating plate 3402 moves with the water level in the water storage chamber 3401. When the water in the water storage chamber 3401 is at the highest water level, the floating plate 3402 conflicts with the connecting plate 32. When a certain amount of water needs to be added, When the water is to be discharged, the stepper motor 3409 is started. When the stepper motor 3409 rotates, it can drive the rotating shaft 3406 to rotate together. When the rotating shaft 3406 rotates, it drives the L-shaped support plate 3407 to rotate together. When the L-shaped support plate 3407 rotates, the water in the water storage chamber 3401 flows out through the water outlet groove 3405, and when the L-shaped support plate 3407 rotates, the long end of the L-shaped support plate 3407 conflicts with the bottom of the floating plate 3402, hindering the movement of the floating plate 3402, so that the floating plate 3402 is always in conflict with the connecting plate 32, and the cooperation between the connecting hole 3403 and the water inlet hole 33 prevents the water on the top of the connecting plate 32 from entering the water storage chamber 3401, so as to achieve the goal of discharging a certain amount of water between the inclined partition plate 31 and the bottom of the inner wall of the dosing shell 30.

[0060] Step 3: During this process, when the floating plate 3402 moves upward with the water level in the water storage chamber 3401, the floating plate 3402 can drive the T-shaped moving plate 3413 to move together, and the T-shaped moving plate 3413 can drive the L-shaped connecting rod 3416 to move together, and the L-shaped connecting rod 3416 can drive the dosing inclined plate 3415 to move together, and the dosing inclined plate 3415 can drive the medicine on its top to move together, and at the same time, the T-shaped moving plate 3413 can drive the telescopic plate 3414 to shrink when the floating plate 3402 moves. When plate 3402 moves to the highest point, the telescopic plate 3414 no longer hinders the medicine on the top of the dosing inclined plate 3415 from entering the medicine outlet groove 3412, so that the medicine on the top of the dosing inclined plate 3415 enters the medicine outlet groove 3412 and is discharged through the medicine outlet groove 3412 to between the inclined partition 31 and the bottom of the inner wall of the dosing shell 30, thereby discharging a certain amount of medicine, and then achieving the mixing of medicine and water in a certain proportion during the dosing and blending, thereby preventing the addition of too much or too little medicine during the dosing and blending, which would cause further damage to the water network.

[0061] Step 4: After the discharge of a drug is completed, the dosing inclined plate 3415 moves downward under the drive of the floating plate 3402. When the dosing inclined plate 3415 moves downward, it can drive the rack 1 65 to move together. When the rack 1 65 moves, it can drive the incomplete gear 66 to rotate. When the incomplete gear 66 rotates, it can drive the rack 2 67 to move upward. When the rack 2 67 moves, it can make the obstruction plate 62 overcome the thrust of the spring 2 64 and move upward, so that the obstruction plate 62 no longer hinders the drug from flowing out from the gap between the baffle 60 and the guide bevel block 61. Then, the drug above the guide bevel block 61 is driven by the pressure plate 68 to move quantitatively from the gap between the baffle 60 and the guide bevel block 61 to the top of the dosing inclined plate 3415, so as to more accurately discharge a certain amount of drug from the drug outlet slot 3412 and achieve a precise ratio of drug and water.

[0062] Step 5: When the water in the water storage chamber 3401 and the medicine in the medicine storage chamber 3411 enter between the inclined partition 31 and the bottom of the inner wall of the medicine adding shell 30, the water in the water storage chamber 3401 will impact the stirring plate 41, causing the stirring plate 41 to rotate under the restriction of the stirring shaft 40. When the stirring plate 41 rotates, it can drive the medicine to rotate together, thereby achieving full fusion of the medicine and water. The fully fused medicine flows into the water network pipe 1 through the medicine adding pipe 42, so that the water and medicine extracted and sent for inspection are mixed and transmitted to the water network, realizing automatic medicine adding and blending of the water network, reducing the operating steps of the operator and preventing the external water from affecting the water network.
