Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shipbuilding application, in particular to a cylinder fixing device of a top-mounted liquid level gauge and a liquid level switch. Background Art
[0002] In general, liquid level is measured by level gauges, and level switches, also called water level switches and level sensors, are switches that control the on / off of circuits through liquid level. For top-mounted level gauges or level switches with a long length, shaking is easy to occur during the operation of the ship. Long-term shaking and friction will shorten their service life and may even break during operation. In order to solve the above problems, the current common practice is to add a pipe clamp to the lower end of the cylinder of the top-mounted level gauge or level switch, and fix the cylinder in a completely locked manner. For the pipe clamp fixed installation method, see Figure 1 Although this pipe clamp solution solves the problem of cylinder shaking, it brings new problems. During the inspection and disassembly of the level gauge and level switch, personnel must enter the cabin to loosen the pipe clamp in advance before they can pull it out smoothly from the top. This requires that the disassembly and inspection of the level gauge and level switch must be carried out after the cabin is emptied, which brings a lot of inconvenience to the maintenance of the equipment. Summary of the invention
[0003] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a cylinder fixing device for a top-mounted liquid level gauge or liquid level switch, which can not only support the cylinder of the top-mounted liquid level gauge or liquid level switch at the bottom end to prevent the cylinder from shaking violently, but also facilitate the direct pulling out of the cylinder without emptying the cabin during maintenance.

[0006] The inner diameter of the sleeve outer cylinder is larger than the outer diameter of the cylinder, and the cylinder is arranged at the center of the sleeve outer cylinder, so that the inner wall of the sleeve outer cylinder and the outer wall of the cylinder are evenly spaced; when the cylinder of the liquid level meter or liquid level switch is inserted into the sleeve outer cylinder, liquid medium flows into the space between the sleeve outer cylinder and the cylinder;
[0007] The auxiliary sleeve is in a trumpet shape, with a small-diameter end smoothly connected to the top of the sleeve-inserted outer cylinder, and a large-diameter end of the auxiliary sleeve-inserted outer cylinder being sleeved outside the cylinder.

[0022] To better understand the technical solution of the present utility model, the following will be described in detail in conjunction with relevant drawings. It should be understood that the following specific embodiments are not intended to limit the specific implementation modes of the technical solution of the present utility model, but are only implementation modes that the technical solution of the present utility model can adopt.

Embodiment 1
[0023] See Figures 2 - 5 , Figure 1 A structural schematic diagram of the present utility model is drawn. As shown in the figure, a cylinder fixing device for a top-mounted liquid level gauge and a liquid level switch according to the present utility model includes an inserted outer cylinder 1, an auxiliary sleeve 2, and a fixing seat 3. The inserted outer cylinder 1 is sleeved outside the cylinder 4 of the top-mounted liquid level gauge and the liquid level switch. An auxiliary sleeve 2 is arranged above the inserted outer cylinder 1, and a fixing seat 3 is connected to the outer wall of the inserted outer cylinder 1.
[0024] The inner diameter of the inserted outer cylinder 1 is 10 mm larger than the outer diameter of the cylinder 4. The cylinder 4 is arranged at the center of the inserted outer cylinder 1, so that the distance between the inner wall of the inserted outer cylinder 1 and the outer wall of the cylinder 4 is 5 mm; a liquid medium is arranged between the inserted outer cylinder 1 and the cylinder 4.
[0025] The auxiliary sleeve 2 is in the shape of a flared mouth. Its small-diameter end is smoothly connected to the top end of the inserted outer cylinder 1, and its large-diameter end assists the inserted outer cylinder 1 to be sleeved outside the cylinder 4; the included angle between the side wall of the auxiliary sleeve 2 and the outer wall of the cylinder 4 is 45°.
[0026] The fixing seat 3 includes a fixing seat body 31. The fixing seat body 31 is in the shape of a square tube. One side of the fixing seat body 31 is welded to the outer wall of the inserted outer cylinder 1. One end face of the fixing seat body 31 is provided with a connecting plate 32. The connecting plate 32 is vertically arranged on the end face of the fixing seat body 31. The fixing seat body 31 is fixed to the side of the hull structure through the connecting plate 32; the connecting plate 32 can adopt a triangular plate.
[0027] Working principle:
[0028] The present utility model provides a cylinder fixing device for a top-mounted liquid level gauge and a liquid level switch, which is composed of three parts: an inserted outer cylinder, a flared mouth-shaped auxiliary sleeve, and a fixing seat.
[0029] (1)The socketed cylinder is a simple cylindrical structure (made of seamless steel pipe). Its inner diameter is 5 mm larger than the outer diameter of the liquid level gauge and liquid level switch cylinders on each side. Under normal operating conditions of the ship, the cabin is filled with liquid medium. When the cylinders of the liquid level gauge and liquid level switch are inserted into the outer socketed cylinder, the liquid medium will flood into the 5-mm gap reserved on each side between the cylinder and the outer socketed cylinder. The 5-mm-thick medium is used as the buffer material between the cylinder and the outer socketed cylinder. Through tests, this 5-mm-thick liquid medium can not only isolate and buffer the collision and friction between the cylinder and the outer socketed cylinder well, but also play a good fixing role, ensuring that the maximum swing amplitude of the liquid level gauge / liquid level switch cylinder does not exceed 5 mm. It not only fixes and supports the equipment cylinder in the best and reasonable way, but also enables the cylinder to be pulled out of the outer socketed cylinder very quickly during disassembly and inspection.
[0030] (2)The flared auxiliary socket is also a capturing device, with a flared shape. Its main function is to facilitate capturing the end of the cylinder when the liquid level gauge and liquid level switch are reinstalled after disassembly and repair, so that the cylinder can be smoothly inserted into the outer socketed cylinder.
[0031] (3)The fixing seat is made of angle steel, aiming to connect and fix the outer socketed cylinder to the side of the ship structure.
[0032] The utility model has the characteristics of light structure, convenient installation, simplicity and flexibility in fixing the longer cylinder of the top-mounted liquid level gauge / liquid level switch.
[0033] The above are only specific application examples of the utility model, which do not constitute any limitation to the protection scope of the utility model. Any technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of the utility model's rights protection.
