Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic heat meters, in particular to a heating pipeline monitoring flow meter based on electronic information. Background Art

[0002] In heating systems, ultrasonic heat meters serve as core monitoring equipment. They calculate fluid flow rate by using the time difference between the flowmeter transmitting and receiving ultrasonic waves, and combine this with temperature sensor data to measure heat energy. However, existing technologies have the following significant drawbacks: 1. Scale adhesion affects measurement accuracy: The fluid in the heating pipe is prone to scale during long-term operation. Scale adheres to the surface of the flow meter and temperature sensor, resulting in obstruction of ultrasonic signal transmission and temperature sensing deviation, ultimately causing distortion of thermal energy measurement data. 2. Lack of automatic descaling mechanism: Traditional equipment relies on manual disassembly and cleaning on a regular basis, which is costly and inconvenient to operate. It is also difficult to achieve real-time online descaling, affecting the continuous operation of the system. 3. Insufficient fluid quality regulation: Without a water quality treatment module, chemicals cannot be added to the pipeline regularly. The corrosive components in the fluid can easily cause corrosion of pipelines and equipment, shortening their service life and increasing the risk of leakage. Therefore, how to achieve automatic descaling and water quality adjustment of heating pipeline monitoring flow meters and improve measurement accuracy and equipment durability is a technical problem that needs to be solved urgently in this field. Summary of the Invention

The time statistics component calculates the usage time of the valve body, so that the dosing component regularly cleans the scale in the valve body.

[0005] Preferably, the purpose is to calculate the working time of the heat energy meter and regularly clean the scale in the valve body, the time statistics component includes a box body installed on the right end of the upper surface of the mounting plate, a timer is installed on the outer wall of the box body, and a first rotating shaft capable of rotation is installed at the center position of the bottom of the box body through a waterproof bearing, and a first bevel gear and a dial plate are installed at the upper and lower ends of the outer wall of the first rotating shaft respectively, and the dial plate can be rotated under the impact of the fluid passing through the valve body, and a slide groove is provided in the middle of the outer wall of the first rotating shaft, and a travel switch electrically connected to the timer is installed on the left inner wall of the box body, and the travel switch is inserted into the inner cavity of the slide groove, and a second rotating shaft capable of rotation is installed on the right inner wall of the box body through a bearing, and a second bevel gear and a cam are installed at the left and right ends of the outer wall of the second rotating shaft respectively, and the second bevel gear is meshed with the first bevel gear, so that the second rotating shaft remains stationary under the action of the gravity of the cam.

[0006] Preferably, both ends of the inner cavity of the chute are inclined surfaces.

[0007] Preferably, the purpose is to add liquid medicine to the fluid to change the water quality of the fluid, the dosing component includes a piston cylinder vertically installed on the left end of the upper surface of the mounting plate, the inner cavity of the piston cylinder is connected with a piston that can move up and down, the bottom of the piston is installed with an ultrasonic vibrating rod, and the ultrasonic vibrating rod is electrically connected to a timer, the high-frequency vibration of the ultrasonic vibrating rod will generate shock waves in the fluid, causing the scale layer on the inner wall of the valve body to fatigue and loosen, a one-way valve is vertically installed on the right end of the bottom of the piston cylinder, the one-way valve is conductive from top to bottom and cut off in the opposite direction, a limiting cylinder is vertically installed on the top of the piston cylinder, a limiting rod that can slide up and down is connected with the inner cavity of the limiting cylinder, and the bottom of the limiting rod is installed with the top of the piston, the piston is pulled up and down by the limiting rod, an insertion rod is installed on the top of the left wall of the limiting rod, and a rotating part is installed on the top of the left wall of the limiting cylinder, the insertion rod is toggled by the rotating part to make the limit rod move up and down, one end of the electromagnetic valve is installed in the middle of the outer wall of the piston cylinder, and the other end of the electromagnetic valve is installed with a medicine tank.

[0008] Preferably, a sealing ring is embedded in the lower surface of the piston cylinder, so that the ultrasonic vibration rod is in close contact with the sealing ring.

[0009] Preferably, the sum of the heights of the piston and the ultrasonic vibration rod is less than or equal to the height of the inner cavity of the piston cylinder.

[0010] Preferably, the rotating part includes a support plate installed on the top of the left side wall of the limiting cylinder, a motor electrically connected to the timer is installed on the lower surface of the support plate, a column is installed at the output end of the motor, a guide groove is opened on the outer wall of the column, and the rod is inserted into the inner cavity of the guide groove.

[0011] Preferably, the guide grooves are distributed on the outer wall of the column in a wave shape.

[0012] The fluid impact force causes the dial to rotate, and the first shaft squeezes the travel switch when it rotates, allowing the timer to calculate the working time of the heat meter. When there is no fluid movement in the valve body, the cam rotates the second shaft under the action of its own gravity. The first shaft can be rotated by cooperating with the second bevel gear, and the travel switch no longer supplies power to the timer. When the internal set value of the timer is reached, the motor drives the cylinder to rotate a certain angle, allowing the guide groove curved surface to squeeze the rod downward, and the limit rod pulls the ultrasonic vibrator down and extends into the valve body. The ultrasonic vibrator shakes off the scale in the valve body, thereby descaling the surface of the flow meter and the temperature sensor, and improving the accuracy of thermal energy measurement.

[0013] When the motor drives the cylinder to rotate continuously, the guide groove can squeeze the rod reciprocatingly up and down, causing the piston to reciprocate up and down. When the piston moves upward, the medicine liquid in the medicine tank flows into the piston cylinder. When the piston moves downward, the piston injects the medicine liquid into the fluid through the one-way valve, changing the properties of the fluid. Therefore, it is possible to regularly and evenly add medicine to the fluid, adjust the water quality of the fluid, and prevent corrosion of pipelines and equipment.

[0014] The present invention proposes a heating pipeline monitoring flow meter based on electronic information, which has the following beneficial effects: 1. The time counting component rotates the first shaft through the impact of fluid on the dial, squeezing the travel switch to trigger the timer, accurately recording the heat meter's operating hours. When the valve body is depleted of fluid, the cam's deadweight rotates the second shaft, resetting the first shaft and stopping the timer. This prevents idling errors and ensures that the descaling cycle matches actual usage. The inclined surfaces at both ends of the slideway ensure that the travel switch automatically switches state as the shaft rotates, eliminating the need for additional power and resulting in a simple and reliable structure.

[0015] 2. When the set time is reached, the motor drives the cylinder to rotate, and the wavy guide groove squeezes the plunger, driving the limit rod downward, allowing the ultrasonic vibrator to extend into the valve body. The high-frequency vibration generates shock waves, which fatigue and loosen the scale layer. This achieves non-contact descaling without the need for chemicals, avoiding damage to the equipment surface. It also simultaneously cleans the flow meter and temperature sensor, significantly improving measurement sensitivity and data accuracy. A sealing ring on the underside of the piston cylinder ensures a sealed connection between the ultrasonic vibrator and the valve body, preventing fluid leakage and ensuring system safety.

[0016] 3. The dosing assembly's motor-driven cylinder rotates continuously, and the guide groove reciprocates to squeeze the rod, causing the piston to move up and down within the cylinder. When the piston moves upward, the solenoid valve opens, drawing the liquid from the tank into the cylinder through the solenoid valve. When the piston moves downward, the one-way valve opens, precisely pumping the liquid into the pipeline. The one-way valve's reverse cutoff function prevents fluid backflow, ensuring a stable and controllable dosing process. The combined height of the piston and ultrasonic vibrator does not exceed the height of the piston cylinder, ensuring that the vibrator can be fully retracted without obstructing normal fluid flow, enabling independent switching between dosing and descaling functions.

[0017] 4. The timer is linked to the motor, and the dosing cycle can be preset according to the operating rules of the heating system, so as to realize the timed and quantitative addition of liquid medicine, effectively adjust the pH or ion concentration of the fluid, inhibit scale formation and equipment corrosion, extend the life of the pipeline, and reduce maintenance costs. The medicine tank and the piston cylinder are connected by a solenoid valve, which can quickly replace different types of medicines to meet the diverse water quality treatment needs and improve system compatibility.

[0018] 5. The descaling mechanism is integrated with the valve body, which does not require additional space and is easy to install. The time statistics component is driven by fluid kinetic energy, which does not require external power supply and is energy-saving and environmentally friendly. The ultrasonic vibration and piston pumping are both controlled by a timer to achieve automatic operation, reduce manual intervention, and improve the intelligence level of the heating system.

[0019] In summary, the present invention realizes the integrated functions of descaling and dosing of the heating pipeline monitoring flow meter through the synergistic effect of mechanical transmission and electronic control, significantly improves the thermal energy measurement accuracy and system reliability, and has significant engineering application value and economic benefits.

DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1-8 The present invention provides a technical solution: a heating pipeline monitoring flow meter based on electronic information, comprising a valve body 1, two flow meters 2, a heat energy meter 3 and a temperature sensor 4. The two flow meters 2 are installed on the outer wall of the valve body 1 at a 45-degree angle, and the two flow meters 2 are positioned correspondingly. The heat energy meter 3 is installed at the center of the outer wall of the valve body 1, and the temperature sensor 4 is installed at the right end of the outer wall of the valve body 1. The flow meters 2 and the temperature sensor 4 are both electrically connected to the heat energy meter 3. The two flow meters 2 can both transmit and receive each other's ultrasonic waves. Affected by the fluid flow rate, there is a time difference between the two flow meters 2 receiving the ultrasonic waves. The heat energy meter 3 uses the time difference to calculate the fluid flow rate. The microprocessor in the heat energy meter 3 calculates the thermal energy through the information provided by the flow meters 2 and the temperature sensor 4. A descaling mechanism 5 is installed on the left side of the outer wall of the valve body 1.

[0024] The descaling mechanism 5 includes a mounting plate 51 installed on the left side of the outer wall of the valve body 1. A dosing component 53 and a time statistics component 52 are respectively installed on the left and right ends of the upper surface of the mounting plate 51. The time statistics component 52 calculates the usage time of the valve body 1, and the dosing component 53 regularly cleans the scale in the valve body 1.

[0025] As a preferred solution, further, the time statistics component 52 includes a box body 521 installed on the right end of the upper surface of the mounting plate 51, and a timer 522 is installed on the outer wall of the box body 521. The working time of the heat meter 3 is counted by the timer 522. A first rotating shaft 523 that can rotate is installed at the center position of the bottom of the box body 521 through a waterproof bearing. The upper and lower ends of the outer wall of the first rotating shaft 523 are respectively installed with a first bevel gear 524 and a dial plate 525. The dial plate 525 can rotate under the impact of the fluid passing through the valve body 1. A slide groove 526 is opened in the middle of the outer wall of the first rotating shaft 523. Both ends of the inner cavity of the slide groove 526 are inclined surfaces. When the first rotating shaft 523 rotates, The limit switch 527 can switch freely between the slide groove 526 and the outer wall of the first rotating shaft 523. The limit switch 527 electrically connected to the timer 522 is installed on the left inner wall of the box body 521, and the limit switch 527 is inserted into the inner cavity of the slide groove 526. The right inner wall of the box body 521 is provided with a rotatable second rotating shaft 528 through a bearing. The left and right ends of the outer wall of the second rotating shaft 528 are respectively provided with a second bevel gear 529 and a cam 5210, and the second bevel gear 529 is meshed with the first bevel gear 524. Under the action of gravity of the cam 5210, the second rotating shaft 528 remains stationary, and the cam 5210 serves as the source of rotational power for the second rotating shaft 528.

[0026] More specifically, the timing is activated: when fluid flows through valve body 1, the fluid's impact force pushes the paddle 525, causing the first rotating shaft 523 to rotate. The first bevel gear 524 then drives the second bevel gear 529 and the cam 5210 to rotate synchronously. At this point, the chute 526 rotates with the rotating shaft, and its inclined surface presses against the contact rod of the travel switch 527, triggering the timer 522 to begin counting the operating time of the heat meter 3.

[0027] Timing stop: When the fluid stops flowing, the cam 5210 drives the second rotating shaft 528 to rotate in the opposite direction under the action of gravity, and the first rotating shaft 523 is reset through gear engagement. The touch rod of the limit switch 527 slides into the slide groove 526, and the timer 522 stops timing to avoid idling and miscounting.

[0028] Periodic triggering: When the timer 522 reaches a preset time, a signal is sent to the dosing component 53 to start the descaling or dosing process to achieve automated maintenance.

[0029] As a preferred solution, further, the dosing component 53 includes a piston cylinder 531 vertically mounted on the left end of the upper surface of the mounting plate 51, and a piston 532 that can move up and down is inserted into the inner cavity of the piston cylinder 531. When the piston 532 moves up and down, the liquid medicine can be pumped into the valve body 1 from the one-way valve 534. An ultrasonic vibrating rod 533 is installed at the bottom of the piston 532, and the ultrasonic vibrating rod 533 is electrically connected to the timer 522. The high-frequency vibration of the ultrasonic vibrating rod 533 will generate shock waves in the fluid, causing the scale layer on the inner wall of the valve body 1 to fatigue and loosen. A sealing ring is embedded in the lower surface of the piston cylinder 531, so that the ultrasonic vibrating rod 533 is in close contact with the sealing ring to prevent leakage of the fluid in the valve body 1. A one-way valve 534 is vertically mounted on the right end of the bottom of the piston cylinder 531. 34. The one-way valve 534 is conductive from top to bottom and cuts off in the opposite direction. A limit cylinder 535 is vertically installed on the top of the piston cylinder 531. A limit rod 536 that can slide up and down is inserted into the inner cavity of the limit cylinder 535, and the bottom of the limit rod 536 is installed with the top of the piston 532. The piston 532 is pulled up and down by the limit rod 536. A plug rod 537 is installed on the top of the left side wall of the limit rod 536. The plug rod 537 is circular in shape, which allows the plug rod 537 to slide smoothly with the guide groove 5384. A rotating part 538 is installed on the top of the left side wall of the limit cylinder 535. The plug rod 537 is moved by the rotating part 538 to make the limit rod 536 move up and down. One end of the electromagnetic valve 539 is installed in the middle of the outer wall of the piston cylinder 531, and the other end of the electromagnetic valve 539 is installed with a medicine tank 5310.

[0030] As a preferred solution, further, the sum of the heights of the piston 532 and the ultrasonic vibrating rod 533 is less than or equal to the inner cavity height of the piston cylinder 531, ensuring that the ultrasonic vibrating rod 533 can be completely received in the piston cylinder 531, preventing the ultrasonic vibrating rod 533 from obstructing the flow of fluid.

[0031] As a preferred embodiment, further, the rotating part 538 includes a support plate 5381 installed on the top of the left side wall of the limiting cylinder 535, and a motor 5382 electrically connected to the timer 522 is installed on the lower surface of the support plate 5381, and a column 5383 is installed at the output end of the motor 5382. A guide groove 5384 is provided on the outer wall of the column 5383, and the insertion rod 537 is inserted into the inner cavity of the guide groove 5384. The guide groove 5384 is distributed in a wave shape on the outer wall of the column 5383. When the motor 5382 drives the column 5383 to rotate, the curved surface of the guide groove 5384 can alternately squeeze the insertion rod 537 upward and downward, thereby causing the limiting rod 536 to reciprocate up and down.

[0032] Descaling Mode: When the timer 522 reaches the descaling trigger time, the motor 5382 drives the cylinder 5383 to rotate a certain angle. The wavy guide groove 5384 squeezes the insertion rod 537 downward, causing the limit rod 536 and piston 532 to descend synchronously. The ultrasonic vibrating rod 533 then passes through the sealing ring and extends into the valve body 1. At this point, the ultrasonic vibrating rod 533 is energized and vibrates at a high frequency, generating shock waves that loosen the scale layer on the inner wall of the valve body 1. After descaling is complete, the motor 5382 rotates in the opposite direction, and the limit rod 536 drives the vibrating rod back into the piston cylinder 531.

[0033] Dosing mode: When water quality needs to be adjusted, the solenoid valve 539 opens, and the medicine tank 5310 is connected to the piston cylinder 531. The motor 5382 continuously drives the cylinder 5383 to rotate, and the guide groove 5384 reciprocates to squeeze the insertion rod 537, so that the limit rod 536 drives the piston 532 to reciprocate up and down: Liquid medicine inhalation: When the piston 532 moves upward, the volume of the inner cavity of the piston cylinder 531 increases, and the liquid medicine in the medicine tank 5310 enters the piston cylinder 531 through the solenoid valve 539 under the action of negative pressure; Liquid medicine injection: When the piston 532 moves downward, the one-way valve 534 is opened, and the liquid medicine is injected into the fluid of the valve body 1 through the one-way valve 534 under the thrust of the piston. The reverse cut-off function of the one-way valve 534 prevents the fluid from flowing back into the piston cylinder 531.

[0034] The sealing ring ensures fluid sealing during the lifting and lowering of the ultrasonic vibrating rod 533. The sliding fit between the circular plug 537 and the wavy guide groove 5384 reduces the transmission resistance. The type of medicine in the medicine tank 5310 can be replaced to adapt to different water quality treatment requirements.

[0035] The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process. The specific operations are as follows.

[0036] Step 1: Under fluid flow conditions, there is a time difference between the signals received by the two flow meters 2. The heat energy meter 3 analyzes the signals fed back by the flow meters 2 and the temperature sensor 4 to calculate the heat energy. In step 2, the impact force of the fluid pushes the dial plate 525 to rotate, thereby rotating the first rotating shaft 523, causing the limit switch 527 to disengage from the chute 526. The first rotating shaft 523 squeezes the limit switch 527 to trigger, and the timer 522 counts the working time of the heat energy meter 3. Under the transmission conditions of the first hammer gear 524 and the second bevel gear 529, the cam 5210 is rotated. When there is no fluid movement in the valve body 1, the cam 5210 rotates the second rotating shaft 528 under the action of its own gravity, and the first rotating shaft 523 rotates. The limit switch 527 enters the chute 526, and the timer 522 stops working, thereby calculating the working time of the heat energy meter 3. Step 3: The motor 5382 is started regularly by the timer 522. The cylinder 5383 rotates a certain angle, and the curved surface of the guide groove 5384 presses the insertion rod 537 downward, causing the limiting rod 536 to slide down along the inner wall of the limiting cylinder 535. The ultrasonic vibrating rod 533 is removed from the piston cylinder 531, and the ultrasonic vibrating rod 533 vibrates. The impact force generated by the ultrasonic wave shakes off the scale on the inner wall of the valve body 1, achieving regular descaling of the valve body 1, improving the sensitivity of the flow meter 2 and the temperature sensor 4, and thus ensuring the accuracy of the data of the heat meter 3. Step 4. When the fluid needs to be purified, the medicine tank 5310 is connected to the piston cylinder 531 through the solenoid valve 539, and the motor 5382 drives the cylinder 5383 to rotate continuously. The curved surface of the guide groove 5384 squeezes the insertion rod 537 back and forth, thereby causing the piston 532 to reciprocate up and down in the piston cylinder 531. When the piston 532 rises, the medicine liquid in the medicine tank 5310 flows into the piston cylinder 531. When the piston 532 descends, the piston 532 squeezes the medicine liquid from the one-way valve 534, evenly adding medicine to the fluid, purifying the fluid and extending the service life of the fluid and pipeline.
