Description

Technical Field

[0001] This invention belongs to the technical field of boiler water level monitoring equipment, and in particular relates to a multi-directional visual electrical contact water level monitoring and transmitting device. Background Technology

[0002] Currently, water level monitoring in coal-fired and gas-fired boilers widely uses electric contact level gauges with transmitting cylinders, most of which are made of metal. Traditional metal transmitting cylinders utilize the properties of metal, with the electric contact terminal connected to the positive terminal and the transmitting cylinder to the negative terminal, using the current flowing through the water level to provide feedback on the water level status. However, because metal is opaque, it is impossible to visually represent the process of water level changes within the cylinder and the corresponding relationship of the electric contact triggering. Furthermore, the traditional electric contact installation structure has limited adaptability, making it difficult to flexibly meet the precise layout requirements of multiple directional and threshold points. If non-metallic materials (such as acrylic) are used to make the transmitting cylinder, there are issues with the cylinder body being non-conductive and unable to be directly used as the negative terminal. Additionally, when simulating water level rises and falls, there is a lack of convenient water filling and draining devices, causing inconvenience for teaching demonstrations and functional debugging.

[0003] In teaching scenarios, metal transmitter cylinders make it difficult for trainees to clearly understand the working logic of electrical contacts under different water levels (such as positive and negative deviation values), and the operation of simulating water level changes is complicated. In actual operation and maintenance, maintenance personnel cannot quickly verify the matching of water level and electrical contact signals through visual means. Traditional base structures are complicated to process and have poor adaptability. Non-metallic cylinders such as acrylic cannot directly apply the original current conduction logic because they are non-conductive. Multiple problems hinder the accurate control of boiler water level and teaching demonstrations. There is an urgent need for a transmitter cylinder solution that combines visualization, customized base, multi-directional electrical contact layout, adaptability to the conductivity requirements of non-metallic cylinders, and convenient simulation of water level rise and fall. Summary of the Invention

[0004] This invention aims to solve the problems of traditional metal sending tanks not being able to intuitively observe water levels, adapting to the conductivity requirements of non-metallic tanks, and the inconvenience of simulating water level rise and fall. It provides a multi-directional visual electrical contact water level monitoring and sending device that combines visualization, a customizable base, multi-directional electrical contact layout, adaptability to the conductivity requirements of non-metallic tanks, and convenient simulation of water level rise and fall.

[0005] To achieve the above-mentioned objectives, the present invention provides a multi-directional visual electrical contact water level monitoring and transmitting device, characterized in that it comprises:

[0006] The main body of the delivery tank is made of transparent non-metallic material to hold and visually display the water level, and a water inlet is provided at the top;

[0007] Multiple electrical contact installation positions are distributed at different heights and orientations on the cylinder wall of the main body of the sending barrel;

[0008] A customized base is fixed to the outside of the main body of the sending barrel and connected to the corresponding electrical contact mounting position for installing electrical contacts;

[0009] The electrical contact terminal is connected to the positive terminal and the negative terminal is connected to the negative terminal, and the current is conducted through the water level.

[0010] The negative electrode rod is disposed inside the main body of the transmitting barrel and is installed vertically through the entire inner wall of the transmitting barrel, forming the negative electrode of the current circuit;

[0011] A drain device is installed at the bottom of the main body of the dispensing tank to control the discharge of liquid inside the tank.

[0012] Furthermore, the multiple electrical contact installation positions are arranged spirally downwards from the top in the left, back, right, and front directions along the four sides of the sending barrel wall, with a spacing of +200, +150, +100, +75, +50, +30, +15, 0, -15, -30, -50, -75, -100, -150, and -200mm, for a total of 15 threshold points.

[0013] Furthermore, the customized base is cut from an acrylic cylinder into multiple independent units, each unit having a threaded hole for installing electrical contact terminals, and is fixed to the electrical contact mounting position on the main body wall of the sending barrel by adhesive bonding.

[0014] Furthermore, the negative electrode rod is made of conductive material, its height is adapted to the internal height of the sending barrel body, and it is arranged along the inner wall of the barrel. The negative electrode wire is connected to the upper side of the negative electrode rod.

[0015] Furthermore, the sewage discharge device includes a drain hole opened at the bottom of the main body of the discharge tank, a connecting base fixed at the drain hole, and a ball valve installed below the connecting base.

[0016] Furthermore, the electrical contact mounting position is adapted to DJ-3 type electrical contacts.

[0017] Beneficial effects of this invention:

[0018] Visual monitoring is achieved: Utilizing high-transmittance acrylic material, changes in water level inside the cylinder and the triggering status of electrical contacts are clearly visible. Whether for teaching demonstrations or fault diagnosis, it provides the most intuitive visual evidence, fundamentally improving the transparency and reliability of monitoring. Trainees can intuitively observe the correspondence between different orientations and different threshold water levels (e.g., +200mm to -200mm) and the triggering of electrical contacts.

[0019] Combining transparency and conductivity: The innovative introduction of an independent negative electrode rod within the transparent cylinder successfully reconstructs the current loop (electrode → water level → negative electrode rod), perfectly solving the conductivity problem of the non-metallic cylinder body, and enabling the visualization design to be realized without changing the core monitoring principle.

[0020] Flexible electrical contact layout and easy installation: A modular, custom-designed base is used. Acrylic cylinders are cut and tapped into independent bases, which can be flexibly attached to any designated location on the cylinder wall like building blocks. This design supports arbitrary placement of points in all four directions of the cylinder, and is simple to process (requiring only cutting and tapping), offering excellent adaptability and easily meeting the needs of multi-threshold, high-density monitoring.

[0021] Convenient water level simulation function: An integrated drain device (ball valve) at the bottom, combined with the water inlet at the top, forms a complete water level simulation system. The entire process of water level rise and fall can be easily and controllably simulated by adding water at the top and draining it at the bottom, making teaching demonstrations more vivid and equipment debugging and function verification more efficient.

[0022] Economic efficiency and compatibility: The core material, acrylic, is low-cost and easy to process; the design is fully compatible with the universal DJ-3 type electrical contacts; and the conductive logic is consistent with traditional systems. This means that users can upgrade to use this device without changing the monitoring system of the boiler body, gaining multiple advantages such as visualization, flexible deployment, and convenient debugging at a lower cost, making it highly valuable for promotion.

[0029] To better understand the purpose, structure, and function of this invention, the following detailed description of a multi-directional visual electrical contact water level monitoring and transmitting device is provided in conjunction with the accompanying drawings.

[0030] This invention develops a multi-directional visual electrical contact water level monitoring and transmitting device, enabling intuitive observation of water levels and accurately presenting the correspondence between multiple directions (four directions) and multiple thresholds (15 points including ±200mm) of electrical contacts and water levels. A customized acrylic base ensures stable installation of the electrical contacts, and a built-in negative electrode rod solves the problem of non-conductivity in the acrylic cylinder, restoring the current conduction logic.

This device meets the high-precision monitoring needs of boiler water levels, improving the convenience and accuracy of operation and maintenance.

[0033] Sending barrel 1: In this embodiment, acrylic material is used, but other transparent non-metallic materials can also be used. The sending barrel has a total height of 600mm, an outer diameter of 90mm, and a wall thickness of 5mm. It has high light transmittance and is used for direct observation of water level changes. A water inlet is provided at the top.

[0034] Electrical contact installation position 3: Along the four sides of the sending tank wall, spiral downwards from the top in the directions of left, back, right, and front, with 15 threshold points set at intervals of +200, +150, +100, +75, +50, +30, +15, 0, -15, -30, -50, -75, -100, -150, and -200mm.

Each part is tapped with an M6×1.5 tap to install electrical contact terminals, thus making a mounting base adapted to electrical contacts. Finally, it is glued and fixed to the electrical contact mounting position 3 of the delivery bucket with acrylic glue.

[0036] Negative electrode rod 4: Since the acrylic cylinder body is non-conductive, a negative electrode rod with a height of 600mm is installed inside the barrel. It is installed vertically through the entire inner wall of the sending barrel. The negative electrode wire is connected to the upper side of the negative electrode rod to form a current conduction circuit and restore the working logic of "the electrical contact terminal is connected to the positive terminal, the negative electrode rod is connected to the negative terminal, and the current is conducted through the water level".

[0037] Sewage discharge device 5: A 10mm hole is made at the bottom of the sending tank, and an acrylic connecting base is attached. A ball valve 6 is connected to the lower side of the base. When the simulated water level rises, water is added at the upper opening. When the simulated water level drops, the ball valve is opened to drain water, realizing convenient water level simulation control.

[0038] 2. Production process

[0039] The multi-directional visual electrical contact water level monitoring and transmitting device of the present invention is designed in strict accordance with the functional requirements of the original metal electrical contact transmitting cylinder of the company's gas furnace, and includes a customized acrylic transmitting cylinder, matching base, built-in negative electrode rod and bottom sewage discharge device.

[0040] Materials required: Acrylic tubing with an outer diameter of 90mm, a wall thickness of 5mm, and a length of 600mm; acrylic cylinder with a length of 450mm and a diameter of 30mm; DJ-3 type electrical contact assembly; acrylic glue; M6×1.5 tap; sealing gasket; matching screws; negative electrode rod with a height of 600mm (conductive material, such as a metal rod); negative electrode wire; 10mm hole acrylic connecting base; ball valve, etc.

[0041] Tools required: cutting equipment, high-precision drilling machine, tapping tools, multimeter (for circuit testing), glue application tools, negative electrode rod installation and fixing tools, ball valve installation tools, etc.

[0042] Base processing: The acrylic cylinder (450mm long and 30mm in diameter) is evenly cut into 15 equal parts to ensure that each part is the same size; each part is tapped through with an M6×1.5 tap to make an electrical contact mounting base;

[0043] Dispatch barrel processing: Cut acrylic tubing to a length of 600mm, grind off the edge burrs to form the main body of the dispatch barrel; precisely mark the opening positions on the acrylic barrel body according to four directions and 15 threshold points (+200 to -200mm), and drill holes using a drilling machine; use acrylic adhesive to attach the 15 processed bases to the openings of the dispatch barrel, ensuring a firm and sealed bond;

[0044] Install the negative electrode rod: Install the 600mm high negative electrode rod through the inner wall of the sending tank, ensuring that it is centered and firmly fixed, and connect the negative electrode wire to the top.

[0045] Bottom drain installation: Drill a 10mm hole at the bottom of the discharge tank, attach an acrylic connecting base, and connect a ball valve to the underside of the base to ensure a tight seal and prevent water leakage;

[0046] Electrical contact installation: Install the DJ-3 type electrical contact through the tapping hole of the base, add a sealing gasket and tighten it to ensure the sealing of the cylinder body;

[0047] System access and debugging: Install the sending tank to the corresponding position on the boiler, connect the water level monitoring circuit, connect the electrical contact terminal to the positive terminal and the negative terminal to the negative terminal;

[0048] The system simulates a rise in water level by adding water through the top opening and a drop in water level by opening the ball valve to drain water, covering the full range of water level changes. A multimeter is used to monitor the electrical contact signal feedback to verify the matching between the water level and the signal.

[0049] 3. Explanation of Innovation Points

[0050] Acrylic is used instead of metal to achieve water level visualization, accurately control the size of the sending tank (600mm high, 90mm outer diameter, etc.), and ensure structural adaptability;

[0051] The first customized acrylic base: through cutting and tapping (M6×1.5) processing, it can be adapted to 15 threshold points and DJ-3 type electrical contacts, solving the problem of poor compatibility of traditional bases;

[0052] Built-in negative electrode design: In view of the non-conductive properties of acrylic, a negative electrode with a height of 600mm is added to restore the current conduction logic (electrical contact is connected to the positive electrode, negative electrode is connected to the negative electrode, and water level conducts current), which is compatible with the original monitoring principle.

[0053] Bottom drainage device: The bottom 10mm hole, together with the acrylic connecting base and ball valve, can easily realize the simulation of water level rise and fall (water addition and drainage) to meet the needs of teaching demonstration and functional debugging.

[0054] Multi-directional layout: Four directions and 15 threshold points (±200mm full range) cover complex water level change scenarios, combining innovation and practicality.
