Description

Technical Field

[0001] This utility model relates to the field of liquid level gauge technology, specifically a fixed structure for a liquid level gauge. Background Technology

[0002] The core function of a level gauge is to reflect changes in liquid level in real time through physical or electronic means. Based on their working principle, level gauges can be divided into various types, such as communicating vessel type, buoyancy type, hydrostatic type, radar type, and ultrasonic type. Among them, the communicating vessel level gauge has become a common choice for monitoring the liquid level of small and medium-sized containers due to its advantages such as simple structure, low cost, and no need for external power. Currently, the glass tube of the communicating vessel level gauge is usually directly exposed. The glass tube itself is fragile and has poor impact resistance. In the complex environment of industrial sites, it is very easy to break due to accidental situations such as collisions or drops of external objects, which reduces the service life of the communicating vessel level gauge.

[0003] As disclosed in the prior art, Chinese utility model publication CN221859664U discloses a fixing structure for a level gauge. This utility model has connecting bends movably installed at both ends of the glass tube body. Sealing sleeves are fitted at both ends of the outer wall of the glass tube body, and the outer wall of the glass tube body has graduations. Two connecting bends are connected to connecting pipes on the side opposite to the glass tube body. Both connecting bends are bent at 90 degrees and have a flared design on their opposite sides. Holes are opened at the opposite ends of both connecting bends, and nuts are embedded in them. The center points of the two nuts are aligned with the center point of the glass tube body. Sealing screws are threaded into the two nuts. In actual use, the glass tube body is exposed, resulting in poor impact resistance. In complex industrial environments, it is easily broken by collisions or drops of external objects, reducing the service life of the level gauge. Therefore, we need to propose a fixing structure for a level gauge. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing structure for a liquid level gauge. By setting a first protective shell and a second protective shell sleeved on the outer wall of the glass tube, and two sets of clamping components for positioning the two, it achieves the effect of blocking external impacts to extend the service life of the glass tube, ensuring the stability of the protective shell and facilitating disassembly and assembly, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fixing structure for a liquid level gauge includes: a liquid level gauge body, a first protective shell, a second protective shell, and a clamping assembly. The liquid level gauge body is mainly composed of a glass tube, a bend, a connecting tube, and a sleeved nut.

[0007] The first protective shell has a second protective shell hinged to one side, and both the first and second protective shells are fitted onto the outer wall of the glass tube.

[0008] Clamping components for positioning the first protective shell and the second protective shell, the two sets of clamping components are respectively disposed on the outer walls of the two sets of bends.

[0009] Preferably, the clamping assembly includes a threaded sleeve, which is fixedly connected to the outer wall of the bend. A sleeve is connected to the outer wall of the threaded sleeve, and a clamping protrusion is provided at the bottom of the sleeve. The clamping protrusion is sleeved on the outer walls of the first protective shell and the second protective shell.

[0010] Preferably, the thread of the sleeve is provided on its outer wall, and the top of the sleeve is threadedly connected to the outer wall of the sleeve.

[0011] Preferably, an anti-detachment ring is fixedly connected to the outer wall of the threaded sleeve.

[0015] Preferably, the dredging component includes an outer tube, which is fixedly connected to the outer wall of the bend, and the inner wall of the outer tube is provided with an internal thread, and the interior of the outer tube is connected to a sealing plug through the internal thread.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention, by setting a first protective shell and a second protective shell and fitting them onto the outer wall of the glass tube, forms a reliable physical barrier. This barrier can effectively block direct collisions and other accidental impacts from external objects, thus properly solving the problem of easy breakage of the glass tube exposed to the outside in traditional level gauges, and significantly extending the service life of the glass tube. At the same time, by using two sets of clamping components to position the first and second protective shells, it can not only ensure that the protective shells remain relatively fixed with the glass tube and the bend, preventing the protective shells from shifting due to vibration and shaking in the industrial environment, thus ensuring the stability of the protective effect, but also enable quick assembly and disassembly of the first and second protective shells, providing convenience for the maintenance and repair of the level gauge.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution:

[0025] A fixing structure for a level gauge includes: a level gauge body 1, a first protective shell 2, a second protective shell 3, and a clamping assembly 4. The level gauge body 1 is the core functional component of the device, mainly composed of a glass tube 101, a bend 102, a connecting pipe 103, and a sleeved nut 104. The bend 102 has a 90-degree bend, with its two ends fixedly connected to the top and bottom ends of the glass tube 101, forming a communicating vessel structure. The connecting pipe 103 is fixedly connected to the side of the bend 102 away from the glass tube 101, for connecting to the communication port of the container to be monitored. The sleeved nut 104 is installed at the end of the connecting pipe 103 away from the bend 102, achieving a sealed connection through external thread engagement with the container's communication port. By setting the above structure of the level gauge body 1, a communication loop is ensured between the level gauge and the container, enabling real-time display of the liquid level within the container and achieving accurate reflection of liquid level changes.

[0026] The first protective shell 2 is hinged to the second protective shell 3 on one side and can be opened and closed relative to each other. When closed, they are together fitted on the outer wall of the glass tube 101 to form a wrap-around protection for the glass tube 101. The clamping components 4 are used to position the first protective shell 2 and the second protective shell 3. The two sets of clamping components 4 are respectively set on the outer walls of the two sets of bent tubes 102.

[0027] There are two sets of clamping components 4, which are respectively installed on the outer walls of the two sets of bent tubes 102 at the top and bottom ends of the glass tube 101. Each set of clamping components 4 includes a threaded sleeve 401, a sleeve 402, a clamping protrusion 403, and an anti-disengagement ring 5: the threaded sleeve 401 is a cylindrical structure, and its inner wall is fixedly connected to the outer wall of the bent tube 102 (such as by welding or integral molding), and the outer wall is machined with external threads; the inner wall of the top end of the sleeve 402 is machined with an internal thread that matches the external thread of the threaded sleeve 401, and is threadedly fitted onto the outer wall of the threaded sleeve 401; the clamping protrusion 403 is an annular flange extending inward from the bottom of the sleeve 402, and its inner diameter is closed with the outer wall of the first protective shell 2 and the second protective shell 3. The diameter is adapted and it is fitted onto the outer wall of the protective shell (first protective shell 2 and second protective shell 3) to achieve a clamping effect; the anti-detachment ring 5 is an annular protrusion fixedly connected to the bottom of the outer wall of the threaded sleeve 401. Its outer diameter is larger than the inner diameter of the sleeve 402. It is used to limit the movement stroke of the sleeve 402. By setting the threaded sleeve 401, sleeve 402, clamping protrusion 403 and anti-detachment ring 5, the thread adjustment is used to achieve a stable clamping of the protective shell by the clamping protrusion 403. At the same time, the anti-detachment ring 5 prevents the sleeve from accidentally falling off, so as to ensure that the protective shell is installed firmly and is easy to disassemble and assemble.

[0028] The second protective shell 3 is provided with an observation window 6. By setting the first protective shell 2, the second protective shell 3 and the observation window 6 in a hinged manner, a physical protective barrier can be formed for the glass tube 101, and the liquid level can be observed directly without opening the protective shell, thus achieving the effect of balancing protection and observation convenience.

[0029] It also includes a sludge-removing component 7 to facilitate the cleaning of the inside of the glass tube 101 and prevent clogging. The sludge-removing component 7 is respectively disposed on the two sets of bends 102. There are two sets of sludge-removing components 7, which are respectively disposed on the outer wall of the two sets of bends 102 (preferably located at the corner where the bend 102 connects to the glass tube 101). The components include an outer tube 701 and a sealing plug 702: the outer tube 701 is a cylindrical tubular structure, one end of which is fixedly connected to the outer wall of the bend 102, and the other end is a free end, with internal threads machined on the inner wall; the sealing plug 702 is a cylindrical structure that matches the internal thread of the outer tube 701, with external threads machined on the outer wall. It seals the free end of the outer tube 701 by connecting to the thread, and the sealing plug 702 achieves a seal when its end face is flush with the free end of the outer tube 701. By setting an outer tube and a sealing plug, when blockage occurs inside the glass tube 101, the sealing plug 702 can be unscrewed, and cleaning fluid or a tool can be inserted into the bend 102 and the glass tube 101 through the outer tube 701 for cleaning. After cleaning, the sealing plug 702 is tightened to restore the seal, thus facilitating the maintenance of the unobstructed flow of the glass tube 101.

[0030] Working principle: First, the connecting pipe 103 is connected to the container opening through the sleeve nut 104, allowing the liquid in the container to enter the glass tube 101 through the connecting pipe 103 and the bend 102. Utilizing the principle of communicating vessels, the liquid level in the glass tube 101 is consistent with the liquid level in the container, thus achieving liquid level display. After the first protective shell 2 and the second protective shell 3 are closed, they are fitted onto the outer wall of the glass tube 101. Through the threaded engagement of the sleeve 402 of the clamping component 4 and the threaded sleeve 401, the clamping protrusion 403 tightly fits the outer wall of the protective shell, ensuring that the protective shell securely encases the glass tube 101 and blocks external impacts. At the same time, the liquid level can be directly observed through the observation window 6 of the second protective shell 3. When blockage occurs inside the glass tube 101 or the bend 102, the sealing plug 702 of the cleaning component 7 is unscrewed, and the blockage is cleaned through the outer tube 701. After cleaning, the sealing plug 702 is tightened to restore the seal, ensuring the normal operation of the liquid level gauge.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
