Description
Technical Field
[0001] This utility model relates to the field of liquid level gauge technology, and in particular to a liquid level gauge with good sealing performance. Background Technology
[0002] A level gauge is an instrument used to measure the height of liquid in a container. It is widely used in industrial production processes such as petroleum, chemical, metallurgy, pharmaceutical, food, and power industries. Currently, most common level gauges require drilling holes in the water tank for installation, which can easily lead to water leakage. At the same time, some level gauges that do not require drilling have a relatively complex structure, such as magnetic float level gauges. The flipping mechanism of its core component, the magnetic reed plate, is relatively complex and prone to mechanical failures or jamming during use. If maintenance is not performed for a long time, the magnetic reed plate may malfunction or even be damaged. To address this, a level gauge with good sealing performance is proposed. It does not require drilling for installation, has a simple structure, and can be used repeatedly for a long time. Utility Model Content
[0003] The purpose of this invention is to further address the shortcomings of existing technologies by providing a liquid level gauge with good sealing performance.
[0004] This device is further configured to achieve the above objectives, and the present invention adopts the following technical solution:
[0005] A well-sealed level gauge includes a first limiting component and a second limiting component, which are respectively disposed on both sides of a plastic housing. The first limiting component includes a measuring shell, with a cover plate installed on the upper end of the measuring shell. The cover plate is removable. A sliding groove is provided on the measuring shell, and the sliding groove has an irregular cross-sectional structure. A water inlet is provided on the outer wall of the measuring shell away from the second limiting component, and the water inlets are arranged in an orderly manner. A float made of plastic is provided inside the measuring shell and is slidably installed in the sliding groove inside the measuring shell. A groove is provided on the side of the float away from the water inlet, and a strong magnet is installed in the groove. The level gauge also includes an indicator ball, which is slidably installed in the second limiting component. The first limiting component and the second limiting component are glued to the inner and outer walls of the plastic housing with glass glue.
[0006] As a further improvement of this utility model: the indicator ball is made of metal, the indicator ball is hollow, and the surface of the indicator ball is coated with colored fluorescent paint.
[0007] As a further embodiment of this utility model: the second limiting component includes a measuring shell, a sliding groove is provided inside the measuring shell, the sliding groove has a circular cross-section, the diameter of the sliding groove is slightly larger than the diameter of the indicator ball, the indicator ball is slidably installed in the sliding groove, and a cover plate is installed above the measuring shell, the cover plate being detachable.
[0008] As a further improvement of this utility model: an opening is provided on the outer wall of the measuring shell two away from the first limiting component, a transparent plate is provided at the opening, and scale bars are provided on the transparent plate, the scale bars being arranged in a specific order.
[0009] As a further improvement of this utility model: the level gauge also includes a fastening component, and a strip-shaped through hole is provided on the transparent plate of the measuring shell, and the fastening component is slidably installed at the through hole.
[0010] As a further embodiment of this utility model: the fastening component includes a handle, an annular part is provided at the end of the handle near the indicator ball, and a pointer is installed at the end of the handle near the scale bar.
[0011] As a further embodiment of this utility model: the fastening component further includes a fixing member, which is installed on the outer wall of the handle away from the pointer. The fixing member is provided with a threaded hole, and a fastening screw is installed in the threaded hole. A rubber pad is provided at the end of the fastening screw near the measuring shell.
[0012] As a further improvement of this utility model: the first limiting component also includes a baffle, which is installed on the outer wall of the measuring shell near the water inlet by fixing bolts, and the baffle is provided with a plurality of filter holes.
[0013] The beneficial effects of this utility model are as follows:
[0014] The first limiting component is installed on the inner wall of the plastic box, and the second limiting component is installed on the outer wall of the plastic box near the first limiting component. The indicator ball is placed in the measuring shell, and water is poured into the plastic box. Under the buoyancy of the water, the float floats up. Due to the irregular shape of the float, the side with the strong magnet always faces the second limiting component. Under the action of the strong magnet, the indicator ball is attracted to the strong magnet, so that the indicator ball can rise with the float. Because the indicator ball is hollow and the strong magnet is strong, the indicator ball and the strong magnet have a strong magnetic attraction. After the water surface stabilizes, the float remains stationary, and the water level in the tank can be roughly checked. There is no need to drill holes in the plastic box. After the plastic box is sealed, it is completely isolated from the outside world to prevent water leakage. At the same time, it is easy to install the level gauge and the operation is simple.
[0015] After the water level in the plastic tank stabilizes, the ring at the end of the sliding lever is brought into contact with the indicator ball, making it easy to record the height using a pointer. If water is poured quickly into the plastic tank, the indicator ball may not follow the float's movement immediately. The lever can be used to lift and slide the indicator ball. After sliding a certain height, the magnetic attraction will cause the operator to feel a change in weight when holding the lever, and resistance will be felt when raising the indicator ball. At this point, the lever should be stopped, thus solving the problem of the indicator ball not following the movement during rapid water pouring. Attached Figure Description

[0023] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.
[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0025] A well-sealed level gauge, such as Figure 1 As shown, the device includes a first limiting component 1 and a second limiting component 2, which are respectively located on both sides of a plastic box 3. The side with the first limiting component 1 is the side of the plastic box 3 used to hold water. The first limiting component 1 includes a measuring shell 4, with a cover plate 5 installed on the upper end of the measuring shell 4. The cover plate 5 is removable. A sliding groove 19 is formed inside the measuring shell 4. The sliding groove 19 has an irregular cross-sectional structure. Multiple water inlets are provided on the outer wall of the measuring shell 4 away from the second limiting component 2. The measuring housing 4 has multiple inlets 6 arranged along its length. A float 9, made of plastic, is installed inside the measuring housing 4 and slidably mounted in a groove 19 within the measuring housing 4. A groove is provided on the side of the float 9 away from the inlets 6, and a strong magnet 22 is installed in the groove. The level gauge also includes an indicator ball 10, which is slidably mounted in the plastic housing 3. The first limiting component 1 and the second limiting component 2 are adhered to the inner and outer walls of the plastic housing 3 with silicone sealant.
[0026] This device is further configured such as Figure 4 As shown, the indicator ball 10 is made of metal. To reduce weight, the indicator ball 10 is hollow. In addition, to make the indicator ball 10 easy to spot, the surface of the indicator ball 10 is coated with colored fluorescent paint.
[0027] The first limiting component 1 is installed on the inner wall of the plastic box 3, and the second limiting component 2 is installed on the outer wall of the plastic box 3 at the position corresponding to the first limiting component 1. The float 9 and the indicator ball 10 are placed in the groove 19 inside the measuring shell 4. Water is poured into the plastic box 3. Under the action of the buoyancy of the water, the float 9 floats up. Due to the irregular structure of the float 9, the side of the float 9 with the strong magnet 22 always faces the second limiting component 2. Under the action of the strong magnet 22, the indicator ball 10 is attracted to the strong magnet 22, so that the indicator ball 10 can rise with the float 9. Because the indicator ball 10 is a hollow structure and the strong magnet 22 is a strong magnet, the indicator ball 10 and the strong magnet 22 can have a strong magnetic attraction. After the water surface is stable, the float 9 remains stationary, and the water level in the bucket can be roughly checked. There is no need to drill holes in the plastic box 3. After the plastic box 3 is sealed, it is completely isolated from the outside world to prevent the plastic box 3 from leaking water.
[0028] This device is further configured such as Figure 3As shown, the second limiting component 2 includes a measuring shell 21, in which a sliding groove 21 is provided. The sliding groove 21 has a circular cross-section and its diameter is slightly larger than that of the schematic ball 10. The schematic ball 10 is slidably installed in the sliding groove 21. A cover plate 20 is installed above the measuring shell 21 and is detachable.
[0029] This device is further configured such as Figure 3 As shown, the measuring shell 11 has an opening on its outer wall away from the first limiting component 1. A transparent plate is provided at the opening, and scale bars 12 are provided on the transparent plate. The scale bars 12 are arranged in an orderly manner. The height of the indicator ball 10 can be observed by using the scale bars 12.
[0030] This device is further configured such as Figure 3 As shown, the level gauge also includes a fastening component 13. A strip-shaped through hole is provided on the transparent plate of the measuring shell 11, and the fastening component 13 is slidably installed at the through hole.
[0031] This device is further configured such as Figure 5 As shown, the fastening component 13 includes a handle 14. An annular component is provided at the end of the handle 14 near the indicator ball 10, and a pointer 15 is installed at the end of the handle 14 near the scale bar 12. After the water level in the plastic tank 3 stabilizes, the handle 14 is slid to bring the annular component at its end into contact with the indicator ball 10, facilitating the recording of the current height using the pointer 15. Simultaneously, if water is rapidly poured into the plastic tank 3, the indicator ball 10 cannot follow the float 9 in time. The handle 14 can be used to lift and slide the indicator ball 10. After sliding a certain height, the magnetic attraction will cause the operator to feel a change in weight when holding the handle 14, and resistance will be felt when raising the indicator ball 10. At this point, the lifting of the handle 14 is stopped, solving the problem of the indicator ball 10 not following the movement during rapid water pouring.
[0032] This device is further configured such as Figure 5 As shown, the fastening component 13 further includes a fixing member 16, which is installed on the outer wall of the handle 14 away from the pointer 15. The fixing member 16 has a threaded hole, in which a fastening screw 17 is installed. A rubber pad 18 is provided at the end of the fastening screw 17 near the measuring housing 11. When it is necessary to fix the handle 14, the fastening screw 17 is rotated, causing the rubber pad 18 to press against the transparent plate of the measuring housing 11, thus fixing the handle 14 under the action of friction.
[0033] This device is further configured such as Figure 2As shown, the first limiting component 1 also includes a baffle 7, which is installed on the outer wall of the measuring housing 4 near the water inlet 6 by fixing bolts 8. The baffle 7 is provided with a plurality of filter holes. By setting the baffle 7, objects in the water in the plastic tank 3 can be prevented from entering.
[0034] Working principle: The first limiting component 1 is installed on the inner wall of the plastic box 3, and the second limiting component 2 is installed on the outer wall of the plastic box 3 at the position corresponding to the first limiting component 1. The indicator ball 10 is placed in the measuring shell 4, and water is injected into the plastic box 3. Under the action of buoyancy, the float 9 floats up. Due to the irregular structure of the float 9, the side of the float 9 with the strong magnet 22 always faces the second limiting component 2. Under the action of the strong magnet 22, the indicator ball 10 is attracted to the strong magnet 22, so that the indicator ball 10 can rise with the float 9. After the water surface stabilizes, the float 9 remains stationary. By sliding the lever 14, the lever 14 can be moved... The annular part at the end is attached to the indicator ball 10, making it easy to record the height at this time using the pointer 15. If water is poured into the plastic box 3 quickly, the indicator ball 10 cannot slide with the float 9 in time. The handle 14 can be used to lift and slide the indicator ball 10. After sliding to a certain height, the magnetic attraction will make the staff feel the change in weight when holding the handle 14. At the same time, resistance will be felt when raising the indicator ball 10. At this time, stop raising the handle 14. When it is necessary to fix the handle 14, turn the fastening screw 17 to make the rubber pad 18 press against the transparent plate of the measuring shell 11, and fix the handle 14 under the action of friction.

However, the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
