A liquid level detection liquid adding device

Abstract

The invention discloses a liquid level detection and liquid adding device, which relates to the field of liquid level detection and liquid adding technology. It is mainly aimed at the detection and liquid adding of the liquid level of a non-transparent shell, and utilizes the certain conductivity of the liquid. When the detection catheter contacts the liquid surface, an audible and visual alarm is issued, and the depth deviation of the actual liquid level from the specified liquid level is measured in conjunction with the scale on the catheter, so as to help the detection personnel to judge the liquid level depth. If liquid needs to be added, it can be directly added through the funnel on the catheter. When the liquid surface reaches the required depth, the liquid detector sends an audible and visual alarm to prompt that the liquid level has reached the limit. The invention changes the current situation that it is difficult or impossible to measure and judge the liquid level depth for non-transparent shells and small-aperture shells, and brings convenience to liquid level detection and liquid adding.

Description

Technical Field

[0001] The invention relates to liquid level depth detection and liquid addition, and in particular to liquid level detection and liquid addition for small boxes and small-caliber non-transparent shell containers. Background Art

[0002] At present, the liquid level depth detection solutions on the market are mainly aimed at tanks, boxes, ponds, rivers, lakes and other large-volume and wide-range liquid levels. Generally, float scales, depth sensors, pressure sensors, ultrasonic waves, lasers and other solutions are used. However, there is a lack of accurate and efficient detection solutions for small boxes and small-caliber non-transparent shell containers. For example, a certain type of battery, because it cannot accurately detect the liquid level and replenish pure water in time, will dry burn, smoke or even catch fire, causing fires and causing great property and personnel losses; because the liquid level cannot be observed directly or indirectly, it is inevitable that excess liquid will overflow when adding liquid, corroding and damaging equipment or causing certain harm to the human body. In summary, in order to avoid such accidents, the development of an accurate, efficient and practical liquid level detection and liquid adding device has become a very urgent and very important task. Summary of the invention

[0003] In view of the above-mentioned problems, the present invention provides an accurate, efficient and practical liquid level detection and liquid adding device. By using the principle of common liquid conductivity, the probe is inserted into the container. When the electrode contacts the liquid surface within the specified depth range, the liquid detector is turned on and an audible and visual alarm is emitted. The detector can know the deviation of the liquid level depth at the specified position through the scale or ruler on the detection catheter, so as to know the difference between the current liquid level and the specified liquid level and judge whether there is a lack of liquid; the detection depth can be adjusted through the scale adjustment ring to meet different detection depth requirements. Fix the detection catheter at the specified liquid level depth for liquid addition. When the liquid surface contacts the detection electrode, the liquid detector emits an audible and visual alarm, indicating that the liquid replenishment is terminated. When not in use, the power supply on the liquid detector can be turned off to save electricity.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A liquid level detection liquid adder includes a detection electrode, a detection conduit, a liquid detector, a funnel, a scale, a scale adjustment ring, etc. The detection conduit, liquid detector, funnel, scale, scale adjustment ring, etc. are made of insulating materials; the detection electrode, liquid detector, funnel, scale, scale adjustment ring, etc. use the detection conduit as a carrier and are fully or partially connected to the detection conduit; at least one end of the detection electrode exposes the lower end of the detection conduit; the scale and the scale adjustment ring are connected together and located at the lower part of the detection conduit; the liquid detector is located in the middle of the detection conduit, can detect various types of water and solutions, and can emit sound and light alarms; the funnel is closely connected to the detection conduit, located at the upper part of the detection conduit, and is used to replenish liquid.

[0006] Specifically, the liquid level detection function and the liquid adding function can be separated or used separately, or used in combination; it can not only measure the depth deviation of the actual liquid level from the specified liquid level, but also accurately add liquid. The funnel and the detection conduit are detachable structures or fixed integrated structures; when the funnel and the detection conduit are detachable structures, a flexible connection can be used.

[0007] The detection conduit can meet the requirements of different liquid level depths by changing the height of the conduit penetrating into the liquid surface; and can meet the requirements of different space usage by changing the horizontal length of the conduit. The detection conduit can be a curved tube or a straight tube according to measurement requirements.

[0008] The detection catheter is provided with a fixed or adjustable scale for facilitating identification of the liquid level depth; the scale can reflect the deviation of the liquid level from the required depth; the scale adjustment ring not only has the function of adjusting the scale, but also has the function of determining the insertion depth of the detection catheter and positioning the catheter; the diameter of the scale adjustment ring is larger than the detection caliber of the container, and has the functions of preventing falling in and self-stabilizing, and does not need to be held by hand.

[0009] The surface of the detection conduit is specially treated and has the function of not sticking to liquid and quickly shedding mucus; after the liquid level detection liquid adder detects the liquid, it is not necessary to wipe the surface of the detection conduit and the next detection can be carried out directly.

[0010] The detection electrode is a metal detection body that is resistant to acid, alkali and salt corrosion and oxidation; the two electrodes for detecting the liquid level are fixed on the surface of the detection catheter or embedded in the detection catheter; or one electrode for detecting the liquid level is fixed on the inner and outer surfaces of the detection catheter or embedded in the detection catheter, and the other detection electrode is connected to the liquid to be measured by other fixing methods.

[0011] In the liquid level detection liquid adder, one end of the detection electrode is connected to the liquid detector, and the other end is used as a measuring electrode.

[0012] The liquid detector can emit a sound or visible light prompt after contacting the liquid through the connected electrodes; the liquid detector has a switch control function.

[0013] The surface material of the liquid level detection liquid adder does not chemically react with the liquid to be detected or the liquid to be added.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0015] The liquid level detection liquid adder described in the present invention is small in size and easy to carry. It is very suitable for detecting the liquid level depth of a small-caliber non-transparent shell. The measurement is accurate and fast. For different depth requirements, the scale can be conveniently adjusted to achieve accurate measurement and easy adjustment. By adding liquid with this product, excessive liquid addition can be avoided to prevent liquid from overflowing, corroding equipment or human body, and avoiding damage. The promotion and application of the present invention will effectively avoid the adverse effects caused by lack of liquid, and bring great convenience to equipment maintenance work.
