Description

Technical Field

[0001] This utility model relates to the field of liquid level gauge protection, specifically a simple adjustable liquid level gauge protection device. Background Technology

[0002] Level gauges are instruments that automatically measure and record the water level of rivers, lakes, and irrigation canals. They have advantages such as good stability, corrosion and wear resistance, and convenient installation, and are widely used in water level measurement for domestic and industrial wastewater. Although level gauges have the advantage of wear resistance, their non-fixed installation allows a large number of solid particles in the wastewater to be in direct contact with them for a long time, further abrading them under relative movement. A large number of suspended solids in the medium interfere with the accuracy of the level gauge and significantly reduce its service life. In municipal and industrial wastewater treatment scenarios, traditional level gauges, due to their fixed installation mode, are difficult to adapt to water level fluctuations and are directly exposed to wastewater containing solid particles, fibers, and corrosive media, making them susceptible to wear, leading to decreased measurement accuracy and shortened lifespan. Furthermore, the rigid, integrated structure makes installation and maintenance inconvenient and occupies a large space. While existing technologies such as adjustable supports and protective sleeves have improved this, they still have drawbacks such as easy loosening of the adjustment mechanism, insufficient sealing protection, and poor space adaptability. Utility Model Content

[0003] The purpose of this utility model is to provide a simple adjustable liquid level gauge protection device. The height can be adjusted by a fixed bracket, an L-shaped cantilever and a threaded cantilever guide rail. The protective sleeve with a grid isolates the liquid level gauge from the sewage medium. With the help of gaskets and sealing rings, it can dynamically adapt to water level changes and protect the liquid level gauge from wear to extend its service life.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A simple adjustable liquid level gauge protection device includes a fixed bracket, characterized in that the fixed bracket is plate-shaped with a bent upper part and a plurality of fixing holes; the lower part of the fixed bracket is provided with one or more straight slots, on which a cantilever is fixedly installed; the other end of the cantilever is provided with a cantilever guide rail, the cantilever guide rail includes a placement groove, and a protective sleeve is installed in the placement groove.

[0006] The cantilever is L-shaped with openings on its side, and is fixedly connected to the straight groove through the openings by bolts and nuts.

[0007] The cantilever guide rail is threaded at its end, and the cantilever is threaded at its end. The cantilever guide rail and the cantilever are installed by threaded engagement.

[0008] The upper end of the fixed bracket has an opening and is fixed to the box body with screws or installed vertically against the wall.

[0009] A gasket is provided between the placement groove and the protective sleeve.

[0010] A grid is installed at the bottom of the protective sleeve.

[0011] The level gauge and its wires are placed inside the protective sleeve.

[0012] This simple adjustable level gauge protection device is fixed to the housing or wall via a bent upper structure on a fixed bracket. An L-shaped cantilever is bolted to the lower straight slot, and the other end of the cantilever is threaded to a cantilever guide rail, allowing for height adjustment. A protective sleeve is installed within the slot of the cantilever guide rail using washers. A grid at the bottom of the sleeve blocks large particles, while the sleeve houses the level gauge and its wiring. The sleeve isolates solid particles, fibers, and corrosive media from the wastewater. Washers and sealing rings enhance sealing and buffering. When the water level changes, the cantilever is loosened from the threaded connection to the guide rail to adjust the height and then locked back in place. Washers at the slot of the fixed bracket protect the wiring from breakage, achieving dynamic positioning, three-dimensional protection, and convenient maintenance of the level gauge, improving its stability and service life under complex operating conditions.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] With adjustable height and strong adaptability to working conditions, the installation height of the level gauge can be adjusted by bolting the straight groove of the fixed bracket to the cantilever and threading the cantilever to the cantilever guide rail. It can flexibly adapt to different water level fluctuation scenarios and meet the needs of changing working conditions without disassembling and reassembling the equipment. It solves the problem of measurement blind spots caused by water level changes in traditional fixed-installation level gauges.

[0015] The protective sleeve completely encloses the level gauge, isolating it from the direct impact and abrasion of solid particles, fibers, and mildly corrosive media in the sewage. The bottom grid further blocks large particulate impurities, reducing contact damage to the probe.

[0016] The gaskets between the placement tank and the protective sleeve, and the sealing rings at the cantilever connection, absorb equipment vibration and water flow impact through elastic materials, avoiding mechanical damage to the level gauge caused by rigid connection, compared to traditional unprotected structures.

[0017] With its compact structure and high space utilization, the fixed bracket adopts a plate-shaped bending design, which can be reliably installed on the wall or fixed to the side of the box, occupying little space. The L-shaped structure of the cantilever and guide rail is reasonably arranged, realizing the adjustment function in a limited space, and is suitable for narrow working conditions.

[0023] like Figure 1-3 As shown, a simple adjustable liquid level gauge protection device includes a fixed bracket 1. The fixed bracket 1 is plate-shaped with a bent upper part and several fixing holes. The lower part of the fixed bracket 1 is provided with one or more straight slots 11, and a cantilever 2 is fixedly installed on the straight slot. The other end of the cantilever 2 is provided with a cantilever guide rail 3. The cantilever guide rail 3 includes a placement groove, and a protective sleeve 4 is installed in the placement groove.

[0024] The cantilever 2 is L-shaped with openings on its side, and is fixedly connected to the straight groove 11 through the openings by bolts and nuts.

[0025] The cantilever rail 3 is threaded at one end, and the cantilever 2 is threaded at one end. The cantilever rail 3 and the cantilever 2 are installed by threaded engagement.

[0026] The upper end of the fixed bracket 1 is opened and fixed to the box body with screws or installed vertically against the wall.

[0027] A gasket 5 is provided between the placement groove and the protective sleeve 4.

[0028] A grille is provided at the bottom of the protective sleeve 4.

[0029] The level gauge and its wire 6 are placed inside the protective sleeve 4.

[0030] In practical implementation, the fixed bracket 1 is a plate-shaped component. Its upper bent structure is connected to the box with screws through fixing holes or installed vertically against the wall with expansion bolts. The lower straight groove 11 is used to install the L-shaped cantilever 2. The side opening of the cantilever is fixed to the straight groove with bolts and nuts to realize the lateral position adjustment. The threaded hole at the other end of the cantilever 2 is threaded with the end of the cantilever guide rail 3. The height can be adjusted vertically by rotating the cantilever guide rail. After the level gauge and its wire 6 are placed in the protective sleeve 4, the sleeve is placed in the placement groove of the cantilever guide rail. The gasket 5 between the placement groove and the sleeve is used for sealing and buffering. The grid at the bottom of the sleeve blocks large particles of impurities. The wire is led out from the groove at the upper bend of the fixed bracket. An auxiliary gasket can be added to the groove for protection. After installation, the level gauge probe is positioned in a suitable measuring position by adjusting the lateral position of the cantilever and the longitudinal height of the guide rail. During maintenance, the threaded connection can be loosened to disassemble the sleeve for cleaning or to replace the wire.
