Description

Technical Field

[0001] This utility model relates to the technical field of interface float level gauges, specifically to interface float level gauges. Background Technology

[0002] Interface-type float level gauges operate based on the principles of buoyancy and magnetic coupling. They are level measuring instruments that use a magnetic float as the measuring element. Through magnetic coupling, the resistance within the sensor changes linearly, which is then converted into a standard current signal for measuring, displaying, and controlling the liquid level. Side-mounted float level gauges offer advantages such as wide applicability, convenient installation, clear readings, and high reliability. However, interface-type float level gauges inevitably encounter impurities and foreign objects in the liquid. When these impurities adhere to the float and rod, they can affect the float's movement and accuracy, causing errors and presenting certain shortcomings. Therefore, we have proposed the interface-type float level gauge. Utility Model Content

[0003] The present invention aims to solve the problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted by this utility model is as follows: an interface-type float level gauge, including a mounting base, a gauge body, a balance rod, a connecting rod, a float, a filter cover, and fasteners. The gauge body is arranged on the left side of the mounting base, the balance rod is arranged on the gauge body, the connecting rod is arranged on the mounting base, the float is arranged on the right side of the connecting rod, the filter cover is arranged on the right side of the mounting base, a gasket is provided on the left side of the filter cover, and the fasteners include a screw arranged on the left side of the gasket and a fastening knob threadedly connected to the screw.

[0005] Preferably, the bottom of the meter body is provided with an interface for connecting to a power source, and the outer side of the meter body is provided with a number of heat sinks for heat dissipation.

[0006] Preferably, the balance bar passes through the mounting base, and the balance bar is rotatably connected to the connecting rod.

[0007] Preferably, the connecting rod is composed of a pendulum rod, a pendulum arm, and a cue stick.

[0008] Preferably, two gaskets are provided, and a sealing ring for sealing is provided on the left side of each of the two gaskets.

[0009] Preferably, four fasteners are provided, and all four fasteners penetrate the mounting base.

[0010] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: By setting a filter cover, this utility model can prevent impurities and foreign objects in the liquid from affecting the movement and accuracy of the float ball due to their attachment to the float ball or rod, without affecting the use of the interface-type float level gauge. At the same time, by setting fasteners, it is convenient to install the filter cover, and the impurities and foreign objects on the filter cover can be removed by swinging. In use, the user can insert the screw of the fastener into the mounting base and rotate the fastening knob to fix it, so as to fix the filter cover for installation. After installation, the filter cover can block impurities and foreign objects in the liquid, preventing impurities and foreign objects from affecting the movement and accuracy of the float ball due to their attachment to the float ball or rod. When there are many impurities and foreign objects on the filter cover, the fastening knob can be loosened. After loosening, the screw can be moved. The moving screw will drive the filter cover to move linearly, which can shake off the impurities and foreign objects on the filter cover for cleaning. Attached Figure Description

[0022] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0023] The following describes some embodiments of the present invention with reference to the accompanying drawings, providing an interface-type float level gauge.

[0024] Example 1:

[0025] Reference Figure 1-3 This is the first embodiment of the present invention, which provides an interface-type float level gauge, including a mounting base 100, a gauge body 200, a balance bar 300, a connecting rod 400, a float 500, a filter cover 600, and fasteners 700.

[0026] Specifically, the meter body 200 is located on the left side of the mounting base 100. The bottom of the meter body 200 is provided with an interface 201 for connecting to the power supply, and the outer side of the meter body 200 is provided with several heat sinks 202 for heat dissipation. In use, the interface 201 can be connected to a cable for data transmission and power connection. The heat sinks 202 have good thermal conductivity for rapid heat dissipation.

[0027] Specifically, the balance bar 300 is installed on the body 200, passes through the mounting base 100, and is rotatably connected to the connecting rod 400. In use, the balance bar 300 serves as a connector between the float 500 and the sensor, transmitting the displacement of the float 500. When the liquid level changes, causing the float 500 to move up and down, the balance bar 300 will tilt accordingly. This change in tilt angle will be captured by the sensor and converted into a corresponding electrical signal.

[0028] Specifically, the connecting rod 400 is arranged on the mounting base 100. The connecting rod 400 is composed of a swing rod, a swing arm and a ball rod. In use, the connecting rod 400 is used to connect the float 500 and facilitate the up and down swing of the float 500 to measure the liquid level.

[0029] Specifically, the float 500 is positioned on the right side of the connecting rod 400. In use, the float 500 can float on the liquid surface to measure the liquid level.

[0030] Specifically, the filter cover 600 is located on the right side of the mounting base 100, and a gasket 601 is provided on the left side of the filter cover 600. There are two gaskets 601, and a sealing ring 602 for sealing is provided on the left side of each gasket 601. During use, the filter cover 600 can block impurities and foreign objects in the liquid, and prevent impurities and foreign objects from affecting the movement and accuracy of the float 500 due to their adhesion to the float or the rod. The sealing ring 602 can improve the sealing performance.

[0031] Specifically, the fastener 700 includes a screw 701 located on the left side of the gasket 601 and a fastening knob 702 threadedly connected to the screw 701. There are four fasteners 700, all of which pass through the mounting base 100. In use, the screw 701 of the fastener 700 can be inserted into the mounting base 100, and the fastening knob 702 can be rotated to fix it, thus fixing the filter cover 600 for installation. When there are many impurities or foreign objects on the filter cover 600, the fastening knob 702 can be loosened. After loosening, the screw 701 can be moved. The moving screw 701 will drive the filter cover 600 to move linearly, thus shaking off the impurities and foreign objects on the filter cover 600 for cleaning.

[0032] The working principle and usage process of this utility model are as follows: When in use, the user can insert the screw 701 of the fastener 700 into the mounting base 100 and rotate the fastening knob 702 to fix it, thereby fixing the filter cover 600 for installation. After installation, the filter cover 600 can block impurities and foreign objects in the liquid, preventing impurities and foreign objects from affecting the movement and accuracy of the float 500 due to their attachment to the float or the rod. When there are many impurities and foreign objects on the filter cover 600, the fastening knob 702 can be loosened. After loosening, the screw 701 can be moved. The moving screw 701 will drive the filter cover 600 to move linearly, thereby shaking off the impurities and foreign objects on the filter cover 600 for cleaning.
