Description

Technical Field

[0001] This invention belongs to the field of buoy level gauge technology, and particularly relates to a positive-reading intelligent remote alarm buoy level gauge. Background Technology

[0002] Patent application CN202420864181.1 discloses a float level gauge with a shielding device, including a first pipe installed on the top of a storage tank and a second pipe installed on the side of the storage tank and parallel to the first pipe. The height of the second pipe is lower than that of the first pipe. Fixed pulleys are installed on the upper part of both the first and second pipes, and the two fixed pulleys are at the same height. A pull line is slidably supported by the two fixed pulleys. One end of the pull line enters the storage tank where the liquid level is to be measured through the first pipe, and a float is fixed at this end. The other end of the pull line enters the second pipe and is fitted with a counterweight. The weight of the counterweight is less than the buoyancy of the float. A shielding device is installed in the first pipe. However, the disadvantage of this technical solution is that it cannot be implemented because the actual design height of the tank may be very high. Ordinary float level gauges use the principle of equal-arm levers, and the liquid level scale used is also very high. Sometimes, it is inconvenient to read the liquid level scale if it is too high. Summary of the Invention

[0003] The purpose of this invention is to provide a positive-reading intelligent remote alarm float level gauge to solve the problem that it is not possible to read the liquid level gauge when the actual design height of the tank may be very high. Ordinary float level gauges use the principle of equal arm levers, and the liquid level scale used is also very high. Sometimes, it is inconvenient to read the liquid level gauge when it is too high.

[0004] To achieve the above objectives, the specific technical solution of the present invention for a positive-reading intelligent remote alarm buoy level gauge is as follows: A forward-reading intelligent remote alarm buoy level gauge includes a tank, a buoy level gauge assembly, a multiplier adjustment device, an indicator assembly, and a counterweight assembly. The buoy level gauge assembly is connected to the tank, the buoy level gauge assembly is connected to the counterweight assembly, the buoy level gauge assembly is connected to the multiplier adjustment device, and the multiplier adjustment device is connected to the indicator assembly.

[0005] Furthermore, the float level gauge assembly includes a lower mounting plate, a guide wire, a first limiting ring, a float, a level indicating ring, a transmission wire, a first steering pulley, an upper mounting plate, a housing, a second steering pulley, a third steering pulley, and a steering pulley shaft. The lower mounting plate is fixedly installed at the bottom of the tank's inner cavity, and one end of the guide wire is also fixedly installed on the lower mounting plate. The other end of the guide wire is installed on the upper cover of the tank via the first limiting ring. The guide wire slides in conjunction with the float. The tank contains liquid, and the float floats in the liquid within the tank. The transmission wire is installed on the float. A first steering pulley is rotatably mounted on the lower mounting plate, and the first steering pulley rolls in cooperation with the transmission steel wire. An upper mounting plate is fixedly mounted on the upper end cover of the tank, and a housing is fixedly mounted on the upper mounting plate. A second steering pulley is rotatably mounted inside the housing, and a steering pulley shaft is rotatably mounted on the housing. A third steering pulley is fixedly mounted on the steering pulley shaft. The transmission steel wire rolls in cooperation with both the second and third steering pulleys. The steering pulley shaft is connected to the ratio adjustment device, and the transmission steel wire is connected to the counterweight assembly. A liquid level indicator ring is installed on the float to be level with the liquid level inside the tank.

[0006] Furthermore, the magnification adjustment device includes a mounting housing, a rotating shaft 1, a transmission shaft 2, mating spur gears 1, 2, 3, and 4, a drive bracket, mating spur gears 5 and 6, a push-button slide, a limiting ring 3, a spring, an opening, positioning slots 1, 2, 3, and 4, and a positioning lever. The mounting housing is fixedly connected to the housing. The rotating shaft 1 and the transmission shaft 2 are rotatably mounted on the mounting housing. Mating spur gears 1, 2, 3, and 4 are fixedly mounted on the rotating shaft 1. Mating spur gear 6 is slidably mounted on the transmission shaft 2 and rotatably mounted on the drive bracket. On the frame, a spur gear five is rotatably mounted on the drive bracket. Spur gear five meshes with spur gear six for transmission, and spur gear six meshes with spur gear one, two, three, or four for transmission. An opening is made in the mounting housing, which also has positioning slot one, two, three, and four. A push-button slide rod is slidably mounted on the drive bracket and is limited by a limit ring three. A spring is provided between the push-button slide rod and the limit ring three. A positioning rod is fixedly mounted on the push-button slide rod and engages with positioning slot one, two, three, or four. Rotating shaft one is fixedly connected to the steering pulley shaft.

[0007] Furthermore, the diameters of the mating spur teeth one, two, three, and four decrease sequentially.

[0008] Furthermore, the display assembly includes a mounting end cap, a mounting roller, mounting bolts, mounting nuts, a roller shaft, a roller rope, a display connecting bracket, a display plate, and an indicator. The mounting end cap and the mounting roller are fixedly connected by mounting bolts and mounting nuts. A display connecting bracket is fixedly installed between the mounting end cap and the mounting roller. A roller shaft is rotatably installed between the mounting end cap and the mounting roller. A roller rope is wound on the roller shaft. One end of the roller rope is fixed to the mounting roller, and the other end of the roller rope is fixed to an indicator. The indicator is slidably installed on the display plate. The roller rope passes through the display connecting bracket, which is fixedly connected to the display plate. The mounting end cap is installed on the mounting housing by bolts, and the roller shaft is fixedly connected to the rotating shaft.

[0009] Furthermore, the maximum transmission ratio between the mating spur gear one and the mating spur gear six is ​​less than 1.

[0010] Furthermore, the display plate is provided with uniform graduations to indicate the liquid level in the tank.

[0011] Furthermore, the counterweight assembly includes a sliding bracket, a water pump, a counterweight sleeve, and a trapezoidal mating groove. The counterweight sleeve is fixedly installed on the sliding bracket, and a water pump is installed on the counterweight sleeve to increase or decrease the counterweight of the counterweight sleeve by controlling water inflow or outflow. A telescopic connecting pipe is installed on the water pump, and the other end of the connecting pipe is installed inside a water tank. The water tank is installed on the outside of the tank body. The counterweight sleeve is connected to a transmission steel wire. A trapezoidal slide rail is fixedly installed on the tank body, and a trapezoidal mating groove is opened on the sliding bracket. The trapezoidal mating groove and the trapezoidal slide rail are in sliding limit engagement.

[0012] The advantages of this invention are: 1. The tank is filled with liquid, and the float floats due to the buoyancy of the liquid. Under the weight of the counterweight, the liquid level indicator ring on the float is level with the liquid surface in the tank. Simultaneously, as the liquid level in the tank rises or falls, the float rises or falls accordingly. This friction between the transmission wire and the three-wheeled guide pulley causes the guide pulley shaft to rotate. The rotating guide pulley shaft is driven by the multiplier adjustment device, and the liquid level in the tank is indicated by the display component. Because the actual design height of the tank may be very high, ordinary float level gauges, which are based on the principle of equal-arm levers, also use very high liquid level scales. Sometimes, excessively high liquid level scales are inconvenient to read. Therefore, by using the multiplier adjustment device and the display component together, the actual design length of the liquid level scale can be reduced, making it easier to read the liquid level in tanks with a high actual design height. 2. When the steering pulley shaft rotates, it drives the rotating shaft one to rotate. The rotating shaft one simultaneously drives the mating spur gears one, two, three, and four to rotate. Initially, mating spur gear one meshes with mating spur gear five, which in turn drives mating spur gear six and transmission shaft two to rotate. Transmission shaft two drives the roller to rotate. Simultaneously, the roller rope drives the indicator to slide along the display plate, which displays the liquid level in the tank. At this time, the positioning lever engages with positioning hole four. The transmission ratio between mating spur gear one and mating spur gear six is ​​at its maximum, resulting in maximum sensitivity and accuracy. Because the maximum transmission ratio between mating spur gear one and mating spur gear six is ​​less than 1, the displayed value... The actual design length of the display plate is reduced to facilitate reading by the operator. When the positioning rod engages with positioning hole four, the rotation amplitude of transmission shaft two is at its maximum, resulting in the highest sensitivity of the indicator and suitability for precise readings. When the positioning rod engages with positioning hole one, the engagement gear four and engagement gear five mesh, resulting in the smallest transmission ratio between engagement gear four and engagement gear six. At this time, the rotation amplitude of transmission shaft two is also at its minimum, resulting in the smallest movement amplitude of the indicator along the display plate, suitable for coarse readings. The switching between different sensitivities can be adjusted according to actual needs. When the positioning rod engages with positioning hole two, the engagement gear three and engagement gear five mesh, and when the positioning rod engages with positioning hole three, the engagement gear two and engagement gear five mesh. 3. As the density of the liquid in the tank changes, the weight of the water in the counterweight sleeve is increased or decreased by controlling the water pump, so that the liquid level indicator ring is flush with the liquid level in the tank.

Detailed Implementation

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] Example 1 like Figure 1-3 As shown in Figure 23, a forward-reading intelligent remote alarm buoy level gauge includes a tank 1, a buoy level gauge assembly 2, a multiplier adjustment device 3, an indicator assembly 4, and a counterweight assembly 5. The buoy level gauge assembly 2 is connected to the tank 1, the buoy level gauge assembly 2 is connected to the counterweight assembly 5, the buoy level gauge assembly 2 is connected to the multiplier adjustment device 3, and the multiplier adjustment device 3 is connected to the indicator assembly 4.

[0017] Example 2 like Figure 5-7 As shown, the float level gauge assembly 2 includes a lower mounting plate 2-1, a guide wire 2-2, a limiting ring 2-3, a float 2-4, a level indicator ring 2-5, a transmission wire 2-6, a first steering pulley 2-7, an upper mounting plate 2-8, a housing 2-9, a second steering pulley 2-10, a third steering pulley 2-11, and a steering pulley shaft 2-12. The lower mounting plate 2-1 is fixedly installed at the bottom of the inner cavity of the tank body 1. The lower mounting plate 2-1 is also fixedly installed at one end of the guide wire 2-2. The other end of the guide wire 2-2 is installed on the upper cover of the tank body 1 through the limiting ring 2-3. The guide wire 2-2 slides against the float 2-4. In a dynamic configuration, tank 1 contains liquid, and buoy 2-4 floats in the liquid within tank 1. A transmission steel wire 2-6 is installed on buoy 2-4. A first steering pulley 2-7 is rotatably mounted on the lower mounting plate 2-1, and the first steering pulley 2-7 rolls with the transmission steel wire 2-6. An upper mounting plate 2-8 is fixedly mounted on the upper end cover of tank 1, and a housing 2-9 is fixedly mounted on the upper mounting plate 2-8. A second steering pulley 2-10 is rotatably mounted inside the housing 2-9, and a steering pulley shaft 2-12 is rotatably mounted on the housing 2-9. A third steering pulley 2-11 is fixedly mounted on the steering pulley shaft 2-12. The transmission steel wire 2-6 simultaneously rotates with the rotating pulley shaft 2-10. The pulleys 2-10 and 2-11 roll in coordination. The shaft 2-12 of the 2-11 steering pulley is connected to the scaling adjustment device 3. The transmission wire 2-6 is connected to the counterweight assembly 5. A level indicator ring 2-5 is installed on the float 2-4 to be level with the liquid surface inside the tank 1. With this configuration, when the tank 1 is filled with liquid, the float 2-4 floats due to the buoyancy of the liquid, and under the gravity of the counterweight assembly 5, the level indicator ring 2-5 on the float 2-4 is level with the liquid surface inside the tank 1. Simultaneously, as the liquid level in the tank 1 rises or falls, the float 2-4 rises or falls accordingly, and this movement is transmitted through the transmission wire 2-6 to the 2-11 steering pulley 2-11. The friction between 11 causes the steering pulley 2-11 to drive the steering pulley shaft 2-12 to rotate. The rotating steering pulley shaft 2-12 is driven by the multiplier adjustment device 3 and the display component 4 to display the liquid level in the tank 1. Since the actual design height of the tank 1 may be very high, the liquid level scale of ordinary float level gauges is also very high because it is based on the principle of equal arm lever. Sometimes it is inconvenient to read the liquid level scale if it is too high. Therefore, by using the multiplier adjustment device 3 and the display component 4 together, the actual design length of the liquid level scale can be reduced, making it easier to read the liquid level in the tank 1 with a higher actual design height.

[0018] Example 3 like Figure 8-14As shown, the magnification adjustment device 3 includes a mounting housing 3-1, a rotating shaft 3-2, a transmission shaft 3-3, a mating spur gear 3-4, a mating spur gear 2, a mating spur gear 3-6, a mating spur gear 4, a drive bracket 3-8, a mating spur gear 5, a mating spur gear 6, a pressing slide rod 3-11, a limiting ring 3-12, a spring 3-13, an opening 3-14, a positioning hole 1 3-15, a positioning hole 2 3-16, a positioning hole 3 3-17, and a positioning... The mounting housing 3-1 is fixedly connected to the housing 2-9, with a four-hole 3-18 and a positioning rod 3-19. A rotating shaft 3-2 and a transmission shaft 3-3 are rotatably mounted on the mounting housing 3-1. A set of mating spur gears 3-4, 3-5, 3-6, and 3-7 are fixedly mounted on the rotating shaft 3-2. A set of mating spur gears 3-10 is slidably mounted on the transmission shaft 3-3. The set of mating spur gears 3-10 is rotatably mounted on the drive bracket 3-8. On the drive bracket 3-8, a mating spur gear 3-9 is rotatably mounted. The mating spur gear 3-9 meshes with the mating spur gear 3-10. The mating spur gear 3-10 meshes with either the mating spur gear 3-4, 3-5, 3-6, or 3-7. An opening 3-14 is provided on the mounting housing 3-1. The mounting housing 3-1 also has positioning holes 3-15, 3-16, 3-17, and 3-18. A push rod 3-11 is slidably mounted on the drive bracket 3-8 and is limited by the limit ring 3-12. A spring 3-13 is provided between the push rod 3-11 and the limit ring 3-12. A positioning rod 3-19 is fixedly mounted on the push rod 3-11. The positioning rod 3-19 cooperates with the positioning hole 1 3-15, the positioning hole 2 3-16, the positioning hole 3-17, or the positioning hole 4 3-18. The rotating shaft 1 3-2 is fixedly connected to the steering pulley shaft 2-12.

[0019] Among them, the diameters of the mating spur teeth 1-4, 2-5, 3-6, and 4-7 decrease sequentially.

[0020] Example 4 like Figure 15-20As shown, the display assembly 4 includes a mounting end cap 4-1, a mounting roller frame 4-2, mounting bolts 4-3, mounting nuts 4-4, a roller 4-5, a roller rope 4-6, a display connecting bracket 4-7, a display plate 4-8, and an indicator 4-9. The mounting end cap 4-1 and the mounting roller frame 4-2 are fixedly connected by the mounting bolts 4-3 and the mounting nuts 4-4. The display connecting bracket 4-7 is fixedly installed between the mounting end cap 4-1 and the mounting roller frame 4-2. The roller 4-5 is rotatably installed between the mounting end cap 4-1 and the mounting roller frame 4-2. The roller rope 4-6 is wound around the roller 4-5. One end of the roller rope 4-6 is fixed to the mounting roller frame 4-2, and the other end of the roller rope 4-6 is fixed to the indicator 4-9. The indicator 4-9 is slidably installed. On the display plate 4-8, the roller rope 4-6 passes through the display connecting bracket 4-7, which is fixedly connected to the display plate 4-8. The mounting end cover 4-1 is bolted to the mounting housing 3-1. The roller 4-5 is fixedly connected to the rotating shaft 3-2. With this configuration, when the steering pulley shaft 2-12 rotates, it drives the rotating shaft 3-2 to rotate. The rotating shaft 3-2 simultaneously drives the mating spur gears 3-4, 3-5, 3-6, and 3-7 to rotate. In the initial position, the mating spur gear 3-4 meshes with the mating spur gear 3-9, and through the mating spur gear 3-9, it drives the mating spur gear 3-10 and the transmission shaft 3-3 to rotate. Drive shaft 2 3-3 drives roller 4-5 to rotate. Simultaneously, roller rope 4-6 drives indicator 4-9 to slide along display plate 4-8, displaying the liquid level in tank 1. At this time, positioning rod 3-19 engages with positioning hole 4-18. The transmission ratio between engaging spur gear 1 3-4 and engaging spur gear 6 3-10 is at its maximum, resulting in maximum sensitivity and accuracy. Because the maximum transmission ratio between engaging spur gear 1 3-4 and engaging spur gear 6 3-10 is less than 1, the actual design length of display plate 4-8 is reduced, facilitating reading by operators. When positioning rod 3-19 engages with positioning hole 4-18, drive shaft 2 3-3 rotates at its maximum amplitude, maximizing the sensitivity of indicator 4-9. The highest sensitivity is suitable for precise readings. When the positioning lever 3-19 is engaged with the positioning hole 3-15, the engaging spur gear 3-7 and the engaging spur gear 3-9 mesh and transmit power. At this time, the transmission ratio between the engaging spur gear 3-7 and the engaging spur gear 3-10 is the smallest, and the rotation amplitude of the transmission shaft 3-3 is the smallest, so that the indicator 4-9 moves along the display plate 4-8 with the smallest amplitude. This is suitable for coarse readings. The switching between different sensitivities can be adjusted according to actual needs. When the positioning lever 3-19 is engaged with the positioning hole 3-16, the engaging spur gear 3-6 and the engaging spur gear 3-9 mesh and transmit power. When the positioning lever 3-19 is engaged with the positioning hole 3-17, the engaging spur gear 3-5 and the engaging spur gear 3-9 mesh and transmit power.

[0021] The maximum transmission ratio between the mating spur gear 3-4 and the mating spur gear 3-10 is less than 1.

[0022] The indicator plates 4-8 are provided with uniform scales to indicate the liquid level in the tank 1.

[0023] Example 5 like Figure 21-23 As shown, the counterweight assembly 5 includes a sliding bracket 5-1, a water pump 5-2, a counterweight sleeve 5-3, and a trapezoidal fitting groove 5-4. The counterweight sleeve 5-3 is fixedly installed on the sliding bracket 5-1. The water pump 5-2, which is used to increase or decrease the counterweight of the counterweight sleeve 5-3 by controlling the water inlet or outlet, is installed on the counterweight sleeve 5-3. A telescopic connecting pipe is installed on the water pump 5-2, and the other end of the connecting pipe is installed in a water tank. The water tank is installed on the outside of the tank body 1. The counterweight sleeve 5-3 is connected to the transmission steel wire 2-6. A trapezoidal slide rail 1-1 is fixedly installed on the tank body 1. The trapezoidal fitting groove 5-4 is opened on the sliding bracket 5-1. The trapezoidal fitting groove 5-4 is slidably limited and engaged with the trapezoidal slide rail 1-1. As the liquid density in the tank body 1 changes, the weight of the water in the counterweight sleeve 5-3 is increased or decreased by controlling the water pump 5-2, so that the liquid level indicator ring 2-5 is flush with the liquid level in the tank body 1.
