[0002] Most of the existing gas holders in our country use a simple structure of a horizontal pipe plus a scale to check the horizontal inclination, which requires personnel to observe during the patrol inspection; a small number of gas holders are improved to use a laser rangefinder to perform laser long-range ranging on the top of the gas holder, with large errors and being greatly affected by environmental factors (such as: foggy weather, large temperature difference weather is prone to condensation of water droplets or icing on the lens, and the laser reflection receiving board is affected by the oil stain in the gas holder and the signal transmission is incorrect, etc.).

[0003] The existing technology has problems that the horizontal inclination detection of the piston and the bridge of the gas holder cannot give timely feedback and alarm, or the detection error is large and it is easy to have false signals, resulting in accidents in production operation.

[0010] Further, there is a sealing flange between the top of the measuring liquid tank and the detector.

[0011] The detector is fixed on the sealing flange, and through this sealing flange, the detector and the measuring liquid tank are in a closed state.

In order to be able to understand the technical means of the present utility model more clearly and implement it in accordance with the content of the specification, the following takes the preferred embodiments of the present invention and combines with the attached drawings to describe in detail as follows. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the following will briefly introduce the drawings required to be used in the embodiments. It should be understood that the following drawings only show a certain embodiment of the present utility model, and therefore should not be regarded as a limitation of the scope. For those of ordinary skill in the art, without creative efforts, other relevant drawings can also be obtained based on these drawings.

[0025] The following combines the accompanying drawings and embodiments to further describe in detail the specific implementation mode of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0026] See Figure 1 , for this device for detecting horizontal inclination, its measuring liquid tank 1 is made of a hollow tank body. A plurality of measuring tank bodies 1 are fixed on the installation surface. There is a lower pipe 3 at its lower end, and the lower pipe 3 is communicated with other measuring tank bodies 1. A certain amount of water is injected into the measuring tank body 1. After the water flows through the lower pipe 3, it is evenly distributed in each measuring tank body 1. At this time, the detector 4 detects the height of the liquid level at this time and records it.

[0027] During the use process, due to various reasons, the liquid level height in the measuring tank body 1 changes. When there is a height deviation in the liquid level, it is the horizontal inclination / balance deviation of the detected part. After the deviation value reaches the process limit value of the detected part, corresponding alarms are given.

[0028] The bottom of the measuring liquid tank 1 is fixedly installed through the flange base 5, which is convenient for installation.

[0029] The detector 4 is installed on the measuring liquid tank 1 through the sealing flange 6, so that the top of the measuring liquid tank 1 is in a sealed state, which is convenient for detection.

[0030] The liquid connection valve 7 installed on the lower pipe 3 can be opened and closed. It is closed first during assembly and opened after the assembly is completed, which is convenient for the liquid to flow between the measuring liquid tanks 1.

[0031] The gas connection valve 8 on the upper pipe 2 is also convenient for the gas to flow between multiple measuring liquid tanks 1, so that the gas pressure between the measuring liquid tanks 1 is balanced.

[0032] There are two types of liquid level gauges 9 on the measuring liquid tank 1. One is to directly open a transparent window on the measuring liquid tank 1, attach high-strength glass to the inner wall of the window, and mark a scale on the glass.

[0033] The other is to connect a glass liquid column to the measuring liquid tank 1 through two upper and lower connecting heads. After the liquid flows into the glass liquid column, it is also convenient to observe the liquid level.

[0034] When workers observe the liquid level gauge 9, they can also find the situation of the liquid level difference, which is used for detection when the electronic facilities fail.

[0035] The working principle of the utility model is as follows:

[0036] In practical applications, the flange base 5 is installed and fixed horizontally and vertically on a large piston or bridge, and liquid is added after connection through a liquid-gas connecting pipe. In the pipeline path, care should be taken to maintain the horizontal error within ≤±5mm for every 2 meters. It is advisable to use 304 fluid delivery pipeline for the pipeline. After it is placed in a static horizontal position, the data is observed and recorded. Then, the detector 4 is installed, tightened and sealed, and the data is checked for comparison. The equipment that produces the error is adjusted during the debugging period and put into operation after the data is consistent. When the liquid level has a high and low deviation, it is the partial horizontal tilt / balance deviation of the detection.

[0037] The horizontal tilt detection equipment can check the internal liquid level height on the stainless steel tank body. During the inspection process, the liquid level data is directly observed and then detected by radar / laser. The data enters the logic controller for analysis to obtain the horizontal tilt of the current piston of the gas tank, thereby ensuring the safety of production operation. At the same time, the sealing of the structure prevents it from being affected by harsh environments, thereby reducing the frequency of personnel entering the danger zone and the number of maintenance times, thereby reducing the occurrence of danger.

[0038] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection. "upper", "lower", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may change;

[0039] Secondly: In the drawings of the embodiments disclosed in the present utility model, only the structures related to the embodiments disclosed in the present utility model are involved, and other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of the present utility model can be combined with each other;

[0040] Finally: The above description is only a preferred implementation mode of the present utility model and is not intended to limit the present utility model. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present utility model.
