Description

Technical Field

[0001] The utility model belongs to the technical field of magnetostrictive liquid level gauges, in particular to a waveguide wire supporting frame for magnetostrictive liquid level gauges. Background Art

[0002] Magnetostrictive level gauges are primarily used for industrial level measurement and control in various liquid tanks, including those used for petroleum, chemical raw material storage, industrial processes, biochemicals, pharmaceuticals, food and beverages, tank farm management, and underground storage at gas stations. They consist of a meter head electronics compartment, a probe rod, and a float. The probe rod houses a waveguide containing a waveguide wire made of a special magnetostrictive material. During measurement, the meter head's circuit unit generates a current pulse, which travels down the waveguide wire and creates a circular magnetic field. A float, mounted on the probe rod, moves up and down along the rod as the liquid level changes. The float, equipped with a permanent magnet, generates a magnetic field. When the current magnetic field meets the float's magnetic field, a "distorted" pulse is generated. The time difference between this pulse and the current pulse is converted into a pulse signal, which is then used to calculate the float's actual position and measure the liquid level.

[0003] As a critical component, the waveguide wire's installation quality directly impacts the overall quality of the device and test accuracy. During installation, the waveguide wire is tensioned. The upper end of the waveguide wire extends into the electronics compartment and is tightened by a tensioning mechanism, while the lower end is secured by a fixing mechanism at the bottom of the waveguide tube. Because different applications require different probe rod lengths, increasing probe rod length can make it difficult to maintain a straight, taut waveguide wire if only tightened at both ends, potentially impacting the tube's inner wall and affecting measurement results. Utility Model Content

[0004] In view of this, in order to solve the above technical problems, the utility model proposes a waveguide wire support frame for a magnetostrictive liquid level gauge, which is used to improve the straightness of the waveguide wire and reduce the risk of accidental bending of the waveguide wire touching the inner wall of the tube, so as to solve the above technical problems.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0006] A waveguide wire support frame for a magnetostrictive liquid level gauge, comprising:

[0007] The frame unit includes two symmetrically arranged support rods, a support seat sleeved on the two support rods, and an upper socket detachably plugged into the upper ends of the two support rods; the support seat is provided with a middle hole for the waveguide to pass through, and the support seat has one or more holes; the upper socket is annular, and its upper and lower end surfaces are provided with plug-in grooves for plugging the support rods;

[0008] The lower socket has the same structure as the upper socket, and the lower socket is detachably connected to the lower ends of the two support rods.

[0009] The waveguide wire support frame is placed as a whole in the waveguide tube; the upper end extends into the electronic compartment and is tightened by the tensioning mechanism, and the waveguide wire at the lower end is fixed by the fixing mechanism at the bottom of the waveguide tube and passes through the middle hole. The support seat plays the role of limiting the position of the waveguide wire. When used in conjunction with the tensioning mechanism and the fixing mechanism, the waveguide wire can be kept in a straight and tightened state, avoiding the situation where the waveguide wire is too long, bends and touches the inner wall, and affects the measurement results.

[0010] Furthermore, the support seat includes a ring, a rubber column arranged in the inner cavity of the ring, and connecting arms symmetrically arranged at both ends of the outer side of the ring; the middle hole is opened on the central axis of the rubber column; the connecting arm is provided with a socket for being mounted on the support rod, and the inner side wall of the socket is provided with an anti-slip pad layer.

[0011] The ring in the support seat is made of hard plastic, and the inside is made of a rubber column with a certain degree of flexibility and elasticity to avoid damaging the waveguide wire; the support seat is inserted into the support rod through the jacks on the connecting arms on both sides. The support seat can be located at any position of the support rod. Due to the presence of the anti-slip pad, when it is moved to the desired position, it can be fixed in this position under the action of friction.

[0012] Furthermore, the plug-in slot and the support rod are detachably connected via threads.

[0013] Furthermore, there are one or more frame units; multiple frame units are connected in series in sequence by inserting the lower end of the support rod of the previous frame unit into the plug-in groove on the upper end surface of the upper plug-in seat of the next frame unit, and the lower plug-in seat is plugged into the lower end of the support rod of the last frame unit.

[0014] According to the actual production length requirements of the magnetostrictive level gauge, multiple frame units are connected in series to form any length to meet different production requirements.

[0015] Furthermore, it also includes end covers, which are two in number and are detachably fastened to the upper socket and the end of the lower socket where the support rod is not installed; the end covers are in the shape of circular ring covers.

[0016] The end cover is buckled on the upper socket and the lower socket to protect the upper socket and the lower socket.

[0017] Furthermore, the end cover is provided with a cavity adapted to the end face of the upper socket, and is provided with an internally threaded mounting hole matching the socket slot, and the inner side wall of the socket slot is also provided with an internal thread; after the end cover is buckled onto the end of the upper socket and the lower socket where the support rod is not installed, it is fixed by inserting bolts into the socket slot and the mounting hole.

[0018] Furthermore, an external thread or an anti-slip pad is provided on the outer side wall of the end cover.

[0019] The waveguide wire support frame is placed as a whole in the waveguide tube, and the outer wall of the end cover is in contact with the inner wall of the waveguide tube. In order to prevent the waveguide wire support frame from sliding, an anti-slip pad is provided on the outer wall of the end cover; an internal thread can also be provided at the corresponding position of the waveguide tube, and an external thread can be provided on the outer wall of the end cover, and the waveguide wire support frame and the waveguide tube can be fixed by a threaded connection.

[0021] (1) The structure of the waveguide wire support frame for the magnetostrictive liquid level gauge described in the utility model is reasonably designed. The waveguide wire passes through the middle hole and is used in conjunction with the tensioning mechanism in the electronic compartment and the fixing mechanism at the bottom of the waveguide tube. When facing a long waveguide wire, it can ensure that the waveguide wire is in a straight and tightened state, avoiding the waveguide wire from bending and touching the inner wall, which affects the measurement results;

[0022] (2) The waveguide wire support frame for the magnetostrictive liquid level gauge described in the utility model can be connected into any length by connecting multiple frame units in series, so as to meet the production requirements of magnetostrictive liquid level gauges of different lengths, and has strong adaptability and easy assembly.
