Description

Technical Field

[0001] The invention relates to the technical field of water level monitoring, and in particular to an intelligent water level measuring gauge and a coating thereof. Background Art

[0002] Setting up multiple water gauges at equal distances from near to far at the edge of reservoirs, lakes and other water bodies is not only convenient for manual patrols to record the liquid level height, but also allows monitoring to be set up nearby to connect to the smart water management integrated platform to achieve long-distance monitoring and alarm of the water level. During use, monitoring often uses its capture and recognition function to perform image recognition on the scale on the water gauge, but because the outdoor light is unstable, it often affects the recognition of monitoring and the observation of manual patrols; although there are lamp beads set inside the water gauge to increase the brightness of the water gauge, the liquid surface will also refract the light submerged in the water, making it difficult to judge the junction of the liquid surface and the water gauge from a distance, causing difficulty in identification, so an intelligent measuring water gauge is needed. Summary of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide an intelligent measuring water gauge and its coating, which has the advantages of easy monitoring and manual identification, good pressure resistance, high measurement accuracy and self-cleaning.

[0004] To achieve the above-mentioned purpose, in the first aspect, the present invention provides an intelligent measuring water ruler, including a shell, a filter assembly, a buoyancy seat and an airtight platform. Among them, a scale is provided on one side of the shell and a light-transmitting hole is provided along the digital pattern on the scale, and the light-transmitting hole is filled with a light-transmitting substance; a plurality of water inlet holes are provided around the side wall of the bottom side of the shell, a water outlet hole is provided on the side wall of the top side of the shell, and a balancing air hole is provided on the top of the shell. The filter assembly is arranged in the shell and is located above the water inlet hole, and water enters the shell after passing through the filter assembly. The buoyancy seat can be movably arranged in the shell and is located above the filter assembly. The buoyancy seat includes a moving platform and a light-emitting component, and the light-emitting component is arranged above the moving platform. Under the action of the liquid level, the buoyancy seat reaches the scale line corresponding to the liquid level and transmits light from the inside of the shell. The airtight platform is slidably arranged in the shell and covers the water outlet in the absence of external force. When the liquid level submerges the scale, the liquid level supports the buoyancy seat to rise against the airtight platform until the airtight platform leaves the water outlet.

[0005] Furthermore, the water level gauge also includes a reinforcement component, the top ring of the airtight platform is provided with a sealing ring, the reinforcement component is respectively connected to the top of the shell and the top of the airtight platform, when the top of the airtight platform reaches the top of the shell, the reinforcement component pulls the airtight platform to abut against the top of the shell.

[0006] Furthermore, a fixing hole is provided on the top of the shell, the reinforcement assembly is arranged in the fixing hole, a boss extends in the fixing hole, the reinforcement assembly includes a sleeve rod and an inner cylinder member, one side of the sleeve rod is rotatably connected to one side of the inner cylinder member, the other side of the sleeve rod is rotatably connected to the boss and a first return spring is provided at the connection between the two, the other side of the inner cylinder member is rotatably connected to the top of the airtight platform and a second return spring is provided at the connection between the two, and the elastic force of the second return spring is greater than the elastic force of the first return spring.

[0007] Furthermore, the buoyancy seat also includes an elastic plate, an elastic layer and a resistance spring. The elastic plate is arranged below the moving platform and the two are connected by a number of resistance springs. The elastic layer is filled between the elastic plate and the moving platform. When the pressure applied to the elastic plate is greater than the elastic force of the resistance spring, the elastic layer deforms so that its side wall is squeezed out from the gap between the elastic plate and the moving platform.

[0008] Furthermore, the filter assembly includes a stepped outer shell and a filter medium. The bottom and side walls of the outer shell are both provided with a plurality of openings, and the filter medium is filled in the outer shell.

[0009] Furthermore, the left and right side walls of the shell are provided with cleaning holes at corresponding positions of the filter assembly, and a switch grid is slidably provided on the cleaning hole on the side close to the filter assembly. Connecting rods are provided on the left and right sides of the airtight platform, and the connecting rods are embedded in the inner wall of the shell and connected to the switch grid. The airtight platform moves up to align the hole on the switch grid with the cleaning hole, thereby realizing water flow on the side wall of the shell.

[0010] Furthermore, a pressure-type water level sensor is provided on the top of the housing.

[0011] Furthermore, buffer rollers are symmetrically provided on both sides of the mobile platform, and the buffer rollers are telescopically connected to the buoyancy seat.

[0012] Furthermore, the water gauge also includes an interception cover, which is arranged around the bottom of the shell body, and a plurality of interception holes are equidistantly arranged on the interception cover.

[0013] In a second aspect, the present invention provides a coating for an intelligent water gauge, which covers the inner and outer surfaces of the measuring water gauge described above, and includes a solute and a solvent. The solute includes 60-80 parts of polysilazane and 20-40 parts of an auxiliary agent in terms of components, and the solvent is ethylene glycol butyl ether.

[0014] By adopting the above technical solution, the beneficial effects of the present invention are:

[0015] The present invention ensures the integrity of the water gauge shell and the pressure resistance of the water gauge by setting light-transmitting holes with scale patterns and filling them with light-transmitting materials. Light can only be emitted from the light-transmitting holes, which is convenient for judging the junction between the liquid level and the water gauge, and is beneficial for monitoring and manual identification. By setting the balancing air holes, a U-shaped tube is formed between the inside of the shell and the liquid level, ensuring that the liquid level inside the shell can be level with the external liquid level, thereby ensuring the measurement accuracy of the buoyancy seat. By making the buoyancy seat mark the liquid level, the laying of lamp beads is reduced, which is more energy-saving and power-saving, and reduces the number of times the battery in the water gauge is replaced. By setting an airtight platform, when the liquid level is about to submerge the water gauge, the air inside the water gauge is discharged in time and the balancing air holes are closed, thereby increasing the water pressure resistance of the water gauge.

[0016] The present invention arranges a reinforcement component, cooperates with a sealing ring, and utilizes mechanical parts to reinforce and seal the connection between the airtight platform and the shell; arranges a buoyancy seat with an elastic layer, and when the buoyancy seat is squeezed by water and the shell, the elastic layer of the inner layer of the buoyancy seat is extruded and squeezes the side wall of the shell, while supporting the airtight platform with a certain weight, and cooperating with the top of the shell to protect the luminous component clamped between the two, preventing the luminous component from malfunctioning due to excessive pressure when the water gauge is submerged, thereby improving the compressive strength of its internal functional components.

[0017] The present invention roughly filters the water entering the housing by setting a filter assembly, and sets cleaning holes on the left and right sides of the filter assembly. When the water gauge is submerged, the airtight platform drives the switch grid to open the cleaning holes on the housing. At this time, the horizontal water flow in the lake or reservoir can directly pass through the filter assembly to automatically clean the inside. The water pressure in the water gauge is accurately measured by setting a pressure water level sensor to achieve accurate measurement of the liquid level.

[0018] By setting a coating of polysilazane components and coating the inner and outer surfaces of the water ruler, its surface anti-aging, hydrophobic and self-cleaning functions are increased, making it better able to adapt to extreme outdoor weather.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but are not used to limit the present invention.

[0037] Reference Figure 1-10 The present invention provides a technical solution: an intelligent water level measuring gauge, comprising a shell 1, a filter assembly 2, a buoyancy seat 3, an airtight platform 4, a reinforcement assembly 5 and an interception cover 7.

[0038] A scale is provided on one side of the housing 1 and a light-transmitting hole 11 is provided along the digital pattern on the scale. The light-transmitting hole 11 is filled with a light-transmitting material, which may be acrylic, glass, etc., which is directly formed in the light-transmitting hole 11 after being melted. A plurality of water inlet holes 12 are provided around the side wall of the bottom side of the housing 1, a water outlet hole 13 is provided on the side wall of the top side of the housing 1, and a balancing air hole 14 is provided on the top of the housing 1.

[0039] The filter assembly 2 is arranged in the housing 1 and above the water inlet 12. Water enters the housing 1 after passing through the filter assembly 2. The filter assembly 2 includes a stepped housing 21 and a filter medium. The bottom and side walls of the housing 21 are provided with a plurality of openings 211. The filter medium is filled in the housing 21, and the filled volume is 2 / 3 of the volume of the housing 21. The filter medium is preferably sand and gravel, and the gaps between the sand and gravel are used to intercept large particles in the liquid.

[0040] The buoyancy seat 3 is movably arranged in the shell 1 and is located above the filter assembly 2. The density of the buoyancy seat 3 is less than that of water, so that it can rise as the liquid level in the shell 1 rises. The buoyancy seat 3 includes a moving platform 31 and a light-emitting component 32. The light-emitting component 32 is arranged above the moving platform 31. A light-emitting lamp bead and a power supply are arranged in the light-emitting component 32. If necessary, a photoelectric sensor can be arranged on the outer surface of the water level to control the light-emitting condition of the light-emitting component 32. In the case of poor light, the buoyancy seat 3 reaches the scale line corresponding to the liquid level due to the action of the liquid level and transmits light from the inside of the shell 1, which is convenient for monitoring and manual identification of readings. In order to ensure the smooth movement of the moving platform 31, buffer rollers 36 are symmetrically arranged on both sides of the moving platform 31, and the buffer rollers 36 are telescopically connected to the buoyancy seat 3.

[0041] The airtight platform 4 can be slidably arranged in the shell 1 and cover the water outlet 13 in the absence of external force. The sliding method can be to set rollers on both sides of the airtight platform 4, and then set sliding grooves at corresponding positions in the shell 1 to limit the movement of the airtight platform 4. The airtight platform 4 has a certain dead weight. When the liquid level submerges the scale, the buoyancy seat 3 inside the shell 1 rises and pushes the airtight platform 4 until the airtight platform 4 completely leaves the water outlet 13. At this time, the gas in the shell 1 is completely discharged from the balance air hole 14 at the top of the shell 1 under the pressure of the airtight platform 4. The setting of the airtight platform 4 can not only prevent debris from entering the shell 1 when the water gauge is not in use, but also increase the bearing capacity of the top of the shell 1 when the water gauge is completely submerged, thereby increasing the pressure resistance of the internal structure of the water gauge.

[0042] In the present invention, in order to increase the connection strength between the airtight platform 4 and the shell 1 when submerged in water, a reinforcement component 5 is arranged between the two, and an elastic plate 33 and an elastic layer 34 are arranged below the buoyancy seat.

[0043] Among them, the reinforcement component 5 is respectively connected to the top of the shell 1 and the top of the airtight platform 4. When the top of the airtight platform 4 reaches the top of the shell 1, the reinforcement component 5 pulls the airtight platform 4 to abut against the top of the shell 1. In order to increase the sealing effect of the airtight platform 4 on the balance air hole 14, a sealing ring 41 can be set on the top ring of the airtight platform 4. The sealing ring 41 is made of rubber. The reinforcement method of the reinforcement component 5 is: a fixing hole 15 is set on the top of the shell 1, and the reinforcement component 5 is set in the fixing hole 15. The reinforcement assembly 5 includes a sleeve rod 51 and an inner cylinder member 52. One side of the sleeve rod 51 is rotatably connected to one side of the inner cylinder member 52. A boss 151 extends in the fixing hole 15. The other side of the sleeve rod 51 is rotatably connected to the boss 151 and a first return spring is provided at the connection between the two. The other side of the inner cylinder member 52 is rotatably connected to the top of the airtight platform 4 and a second return spring is provided at the connection between the two. The first spring and the second spring respectively give the sleeve rod 51 and the inner cylinder member 52 pre-rotation forces in opposite directions, and the rotation radius of the sleeve rod 51 is smaller than the rotation radius of the inner cylinder member 52. The elastic force of the first return spring is greater than the elastic force of the second return spring. Figure 9-10 During the rising process of the airtight platform 4, the sleeve rod 51 pulls the inner cylinder 52 to swing until the connection point between the inner cylinder 52 and the sleeve rod 51 passes the connection point between the sleeve rod 51 and the boss 151. The greater the water pressure on the sleeve rod 51, the smaller the angle between it and the top of the shell 1, thereby making the contact between the airtight platform 4 and the shell 1 tighter. When the water level is exposed to the water surface, the pressure above the sleeve rod 51 is lost. At this time, the second return spring in the sleeve rod 51 works to cooperate with the airtight platform 4 with a certain dead weight, so that the inner cylinder 52 rotates to cause the airtight platform 4 to descend and reset.

[0044] At the same time, in order to prevent the water inside the shell 1 from squeezing the light-emitting element 32, the buoyancy seat 3 also includes an elastic plate 33, an elastic layer 34 and a resistance spring 35. The elastic plate 33 is arranged below the moving platform 31 and the two are connected by a number of resistance springs 35. The resistance spring 35 is used to offset the deadweight of the buoyancy seat 3 and the friction between the buoyancy seat 3 and the shell 1. The elastic layer 34 is filled between the elastic plate 33 and the moving platform 31. The elastic layer 34 can be silica gel or an air bag. When the water submerges the water gauge, the pressure on the elastic layer 34 is greater than the elastic force of the resistance spring 35. At this time, the elastic layer 34 is deformed by force and its side wall is squeezed out from the gap between the elastic plate 33 and the moving platform 31 to fill the gap between the buoyancy seat 3 and the shell 1. At this time, the buoyancy seat 3 is fixed in the shell 1 under the action of the elastic layer 34, which increases the support for the airtight platform 4 while preventing the water in the shell 1 from entering the surrounding of the light-emitting element 32 and causing damage.

[0045] Because the water gauges are set at equal distances on the shore, some of the water gauges will be immersed in water for a long time. At this time, the lateral flow channel of water is used to realize the self-cleaning of the filter assembly 2 in the water gauge. Specifically, the left and right side walls of the shell 1 are provided with cleaning holes 16 at the corresponding positions of the filter assembly 2. The cleaning hole 16 is slidably provided with a switch grid 17 on the side close to the filter assembly 2. The size and spacing of the holes on the grid are consistent with the cleaning holes 16. When the holes on the switch grid 17 and the cleaning holes 16 are staggered, the side wall of the shell 1 remains closed. Connecting rods 42 are provided on the left and right sides of the airtight platform 4. The connecting rods 42 are embedded in the inner wall of the shell 1 and connected to the switch grid 17. The airtight platform 4 moves up to align the holes on the switch grid 17 with the cleaning holes 16, so as to realize the flow of water on the side wall of the shell 1.

[0046] In order to realize the intelligent water level test of the water gauge, a pressure water level sensor 6 can be provided on the top of the housing 21 of the filter assembly 2. The pressure water level sensor 6 converts the water pressure into the water level depth, and the accuracy can reach 2mm. The maximum water depth can reach 300 meters, which can achieve the purpose of high-precision and continuous water level measurement. The diffused silicon piezoresistive pressure sensor with high stability, high reliability and high precision is selected to accurately measure the liquid static pressure proportional to the liquid depth. After a high-reliability amplification circuit and precision temperature compensation, it is converted into a standard voltage or current signal output. The output signal has a linear correspondence with the depth of the liquid, and the liquid level depth can be measured, realizing both electronic measurement and manual monitoring.

[0047] The interception cover 7 is arranged around the bottom of the shell 1 , and a plurality of interception holes 71 are arranged at equal intervals on the interception cover 7 . The interception cover 7 can increase the fixing strength of the water gauge and can also perform preliminary interception on the water inlet 12 .

[0048] In the second aspect, in order to increase the service life of the water gauge, the present invention provides a coating for an intelligent water gauge, which covers the inner and outer surfaces of the water gauge described above, and includes a solute and a solvent, wherein the solute includes 60-80 parts of polysilazane and 20-40 parts of an auxiliary agent, and the solvent is ethylene glycol butyl ether. The auxiliary agent may be an epoxy resin or a polyester, which is used to increase the softness of the polysilazane.

[0049] The coating was sprayed on the surface of the water gauge for performance testing. During the spraying process, the dry film thickness was controlled at 20-150μm and the curing time was 24h. The performance table of the coating can be obtained as follows:

[0050] Table 1: Summary of coating characterization

[0052] Therefore, it can be judged that the coating in the present invention has the advantages of good hydrophobic effect, poor electrical conductivity, and good resistance to artificial aging, and is more suitable for use in water gauges that are exposed to the outdoors for a long time.

[0053] Working principle: At the place where the test is required, multiple water gauges are fixed in sequence from near to far at equal distances. When the liquid level reaches the water gauge, the buoyancy seat 3 in the shell 1 illuminates and moves inside the shell 1 until it reaches the scale line, realizing the luminous mark of the liquid level height.
