Description

Technical Field

[0001] The invention relates to the technical field of intelligent float type flowmeters, in particular to an intelligent float type flowmeter with a heat insulation structure. Background Art

[0002] An intelligent float flowmeter is an instrument for measuring flow by moving a float up and down in a vertical tapered tube. It is suitable for flow measurement in a variety of fluid media and industrial fields, such as water, gas, and steam, and is widely used in industries such as power, chemical, petroleum, and water treatment.

[0003] In winter, the outdoor temperature is relatively low, and the intelligent float flowmeter needs to be insulated. The general insulation method of the existing intelligent float flowmeter is to manually wrap insulation material around its flow meter to prevent the water flow in the flow meter from freezing and ensure that the device works normally in winter. Some heating methods are to cover the flow meter with a shell and then heat the inside of the shell. However, the temperature of this heating method is uncontrollable. As the water flow in the pipeline and the temperature inside the shell alternate between hot and cold, the flow meter is prone to rupture. At the same time, as the heating time increases, the high temperature will also cause the flow meter to deform, thereby damaging the intelligent float flowmeter. It is impossible to ensure that the life of the intelligent float flowmeter is guaranteed while heating. Improvements are needed to address this problem.

[0004] Therefore, it is necessary to design an intelligent float flowmeter with a heat-insulating structure that is highly practical and can ensure its service life when the temperature is low in winter. Summary of the Invention

[0005] The object of the present invention is to provide an intelligent float flowmeter with a heat-insulating structure to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: an intelligent float-type flowmeter with a thermal insulation structure, comprising a flow meter, a heating mechanism, a heat dissipation mechanism and a blower mechanism, wherein a drive box is fixedly connected to the middle of the outer side of the flow meter, and a display is fixedly connected to the front end of the right side of the drive box.

[0007] Wherein, the heating mechanism comprises:

[0008] The fixed frame is fixedly connected to the middle of the front of the flow meter. A heating rod is provided on the front of the fixed frame. The right side of the fixed frame is fixedly connected to an insulation shell, and a gas guide thread is provided on the inner wall of the insulation shell.

[0009] According to the above technical solution, the heat dissipation mechanism includes a heat dissipation box, a movable plate, a guide pulley, a guide chute, a magnetic block, an electromagnet and a spring. The heat dissipation box is fixedly connected to the top outside the flow meter, the spring is fixedly connected to the left side of the bottom inside the heat dissipation box, the movable plate is fixedly connected to the top of the spring, the guide pulley is rotatably connected to the bottom of the front and back of the movable plate, the guide chute is fixedly connected to the inner wall of the front and back of the heat dissipation box, the magnetic block is fixedly connected to the top of the movable plate, and the electromagnet is fixedly connected to the left side of the top inside the heat dissipation box.

[0010] According to the above technical solution, the blowing mechanism includes a driving motor, an elliptical disc, an airbag, an extrusion plate, a blowing pipe and an air suction pipe. The driving motor is fixedly connected to the middle left side of the driving box. The driving motor has an output shaft. The elliptical disc is fixedly connected to the output shaft of the driving motor. The airbag is fixedly connected to the left side of the top of the driving box. The extrusion plate is fixedly connected to the bottom of the airbag. The blowing pipe is fixedly connected to the front side of the top of the airbag. The air suction pipe is fixedly connected to the rear side of the top of the airbag.

[0011] According to the above technical solution, the interior of the fixed frame is connected to the interior of the insulation shell, and the inner ring of the insulation shell is fitted with the outer wall of the flow meter, so that the air in the fixed frame can be filled into the insulation shell.

[0012] According to the above technical solution, interconnected ventilation grooves are provided on the left side of the heat dissipation box, the left side of the movable plate and the right side of the movable plate on the same horizontal line. The guide pulley is arranged in the guide slide groove. The movable plate is slidably connected to the guide slide groove through the guide pulley, so that the movable plate can be guided when it is raised or lowered.

[0013] According to the above technical solution, the top ends of the blowing pipe and the suction pipe both pass through the top of the drive box and the bottom of the heat dissipation box and extend into the heat dissipation box. A one-way valve 1 is provided in the top opening of the suction pipe, and the input end of the one-way valve 1 is on the rear side. A one-way valve 2 is provided in the top opening of the blowing pipe, and the input end of the one-way valve 2 is on the rear side. By setting the one-way valve 1 and the one-way valve 2, the blowing pipe can be controlled to blow air, and the suction pipe can inhale air.

[0014] According to the above technical solution, the front and back inner walls of the heat dissipation box are provided with heat-insulating materials, and the movable plate is made of hard rubber, which can insulate the interior of the heat dissipation box.

[0015] According to the above technical solution, a battery is fixedly connected to the bottom of the heat dissipation box, and the battery is electrically connected to the heating rod and the electromagnet, so that the battery can power the heating rod and the electromagnet. A timer is provided on the back of the heat dissipation box.

[0016] Compared with the prior art, the present invention has the following beneficial effects: when the interface end of the intelligent float flowmeter needs to be kept warm, the heating rod is turned on. When the heating rod is working, the fixing frame and the insulation shell are heated, so that the temperature inside the fixing frame and the insulation shell is increased. At the same time, after the temperature is increased, the insulation shell transmits the temperature to the flow meter through the inner ring, thereby performing insulation and heating work on the inside of the flow meter, preventing the temperature inside the flow meter from being too low and causing the internal water to freeze, thereby ensuring the normal operation of the display instrument;

[0017] When heat preservation is needed, the battery supplies power to the electromagnet. At this time, the electromagnet produces magnetic attraction on the magnetic block, causing the magnetic block to rise. At the same time, the spring is stretched to cause the movable plate to rise. At this time, the movable plate rises in the guide chute through the guide pulley, which can guide the rise of the movable plate. At the same time, due to the rise of the movable plate, the heat dissipation box and the ventilation slots on the movable plate are misaligned. At the same time, the movable plate blocks the ventilation slots, which can reduce the temperature loss in the heat dissipation box. In order to avoid deformation and damage caused by overheating of the pipeline when the flow measuring instrument is continuously heated, a timer can be set to regularly cool the temperature in the heat dissipation box. After the timer expires, the battery cuts off power to the electromagnet. At this time, the magnetic attraction force between the electromagnet and the magnetic block is less than the elastic rebound force of the spring, causing the movable plate to fall. At this time, the movable plate is connected with the ventilation slots on the heat dissipation box, which can cool the heat dissipation box and ensure the service life of the flow measuring instrument.

[0018] When it is necessary to evenly distribute the temperature on the outer wall of the flow meter, turn on the drive motor. The drive motor can drive the elliptical disc to rotate when working. When the elliptical disc rotates, the elliptical disc contacts and squeezes the extrusion plate, so that the air bag on the upper side of the extrusion plate is squeezed. At this time, the air in the air bag is blown through the one-way valve 2 in the blowing pipe, so that the air in the fixed frame and the insulation shell contacts the gas guide thread on the inner wall of the insulation shell, which can guide the air and make it rotate and rise to the top of the insulation shell. At this time, when the hot air moves upward around the gas guide thread, it evenly sweeps the inner wall of the inner ring of the insulation shell, so that the temperature on the inner wall of the insulation shell can be more uniform, thereby avoiding damage to the flow meter due to excessive heating temperature at the heating rod, and ensuring the service life of the flow meter.

[0028] 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.

[0029] See also Figure 1-5 The present invention provides a technical solution: an intelligent float-type flowmeter with a heat-insulating structure, comprising a flow meter 1, a heating mechanism 4, a heat dissipation mechanism 6 and a blower mechanism 7. A drive box 3 is fixedly connected to the middle of the outer side of the flow meter 1, and a display 5 is fixedly connected to the front end of the right side of the drive box 3.

[0030] Wherein, the heating mechanism 4 includes:

[0031] The fixing frame 401 is fixedly connected to the middle of the front of the flow meter 1. A heating rod 402 is provided on the front of the fixing frame 401. An insulation shell 403 is fixedly connected to the right side of the fixing frame 401. A gas guide thread 404 is provided on the inner wall of the insulation shell 403.

[0032] The heat dissipation mechanism 6 includes a heat dissipation box 601, a movable plate 602, a guide pulley 603, a guide chute 604, a magnetic block 605, an electromagnet 606 and a spring 607. The heat dissipation box 601 is fixedly connected to the top outside the flow meter 1, the spring 607 is fixedly connected to the left side of the bottom inside the heat dissipation box 601, the movable plate 602 is fixedly connected to the top of the spring 607, the guide pulley 603 is rotatably connected to the bottom of the front and back of the movable plate 602, the guide chute 604 is fixedly connected to the inner wall of the front and back of the heat dissipation box 601, the magnetic block 605 is fixedly connected to the top of the movable plate 602, and the electromagnet 606 is fixedly connected to the left side of the top inside the heat dissipation box 601.

[0033] The interior of the fixing frame 401 is connected to the interior of the insulation shell 403 , and the inner ring of the insulation shell 403 fits the outer wall of the flow meter 1 , so that the air in the fixing frame 401 can be filled into the insulation shell 403 .

[0034] The left side of the heat dissipation box 601, the left side of the movable plate 602, and the right side of the movable plate 602 are all provided with interconnected ventilation slots on the same horizontal line. The guide pulley 603 is arranged in the guide chute 604. The movable plate 602 is slidably connected to the guide chute 604 through the guide pulley 603, which can guide the movable plate 602 when it is raised or lowered.

[0035] The front and back inner walls of the heat dissipation box 601 are provided with heat-insulating materials, and the movable plate 602 is made of hard rubber, which can keep the inside of the heat dissipation box 601 warm.

[0036] A battery is fixedly connected to the bottom of the heat dissipation box 601 , and the battery is electrically connected to the heating rod 402 and the electromagnet 606 , so that the battery can power the heating rod 402 and the electromagnet 606 . A timer is provided on the back of the heat dissipation box 601 .

[0037] When the interface end of the intelligent float flowmeter needs to be kept warm, the heating rod 402 is turned on. When working, the heating rod 402 heats the fixing frame 401 and the insulation shell 403, thereby increasing the temperature inside the fixing frame 401 and the insulation shell 403. At the same time, after the temperature is increased, the insulation shell 403 transmits the temperature to the flowmeter 1 through the inner ring, thereby keeping the flowmeter 1 warm and heating the inside, thereby preventing the temperature inside the flowmeter 1 from being too low and causing the internal water to freeze, thereby ensuring the normal operation of the display 5.

[0038] When heat preservation is needed, the battery supplies power to the electromagnet 606. At this time, the electromagnet 606 produces magnetic attraction to the magnetic block 605, causing the magnetic block 605 to rise. At the same time, the spring 607 is stretched, causing the movable plate 602 to rise. At this time, the movable plate 602 rises in the guide slot 604 through the guide pulley 603, which can guide the rise of the movable plate 602. At the same time, due to the rise of the movable plate 602, the ventilation slots on the heat dissipation box 601 and the movable plate 602 are misaligned. At the same time, the movable plate 602 blocks the ventilation slots, which can reduce the temperature in the heat dissipation box 601. In order to prevent the flow meter 1 from being deformed and damaged due to overheating of the pipe when it is continuously heated, a timer can be set to regularly dissipate heat in the heat sink 601. After the timer expires, the battery cuts off the power to the electromagnet 606. At this time, the magnetic attraction between the electromagnet 606 and the magnetic block 605 is less than the elastic rebound force of the spring 607, causing the movable plate 602 to drop. At this time, the movable plate 602 is connected to the ventilation slot on the heat sink 601, which can dissipate heat in the heat sink 601 and ensure the service life of the flow meter 1.

[0039] See also Figure 6-7 The present invention provides a technical solution: the blowing mechanism 7 includes a driving motor 701, an elliptical disc 702, an airbag 703, an extrusion plate 704, a blowing pipe 705 and an air suction pipe 706. The driving motor 701 is fixedly connected to the middle of the left side of the driving box 3. The driving motor 701 has an output shaft. The elliptical disc 702 is fixedly connected to the output shaft of the driving motor 701. The airbag 703 is fixedly connected to the left side of the top of the driving box 3. The extrusion plate 704 is fixedly connected to the bottom of the airbag 703. The blowing pipe 705 is fixedly connected to the front side of the top of the airbag 703. The air suction pipe 706 is fixedly connected to the rear side of the top of the airbag 703.

[0040] The top ends of the blowing pipe 705 and the suction pipe 706 both pass through the top of the drive box 3 and the bottom of the heat sink 601 and extend into the heat sink 601. A one-way valve 1 is provided in the top opening of the suction pipe 706, and the input end of the one-way valve 1 is on the rear side. A one-way valve 2 is provided in the top opening of the blowing pipe 705, and the input end of the one-way valve 2 is on the rear side. By setting the one-way valve 1 and the one-way valve 2, the blowing pipe 705 can be controlled to blow air, and the suction pipe 706 can be controlled to inhale air.

[0041] When the temperature on the outer wall of the flow meter 1 needs to be evenly distributed, the drive motor 701 is turned on. The drive motor 701 can drive the elliptical disc 702 to rotate when working. When the elliptical disc 702 rotates, the elliptical disc 702 contacts and squeezes the extrusion plate 704, so that the air bag 703 on the upper side of the extrusion plate 704 is squeezed. At this time, the air in the air bag 703 is blown through the one-way valve 2 in the blowing pipe 705, so that the air in the fixed frame 401 and the insulation shell 403 contacts the gas guide thread 404 on the inner wall of the insulation shell 403, which can guide the air and make the air rotate and rise to the top of the insulation shell 403. At this time, when the hot air moves upward around the gas guide thread 404, it evenly sweeps the inner wall of the inner ring of the insulation shell 403, so that the temperature on the inner wall of the insulation shell 403 can be made more uniform, avoiding damage to the flow meter 1 due to excessive heating temperature at the heating rod 402, thereby ensuring the service life of the flow meter 1.
