Description

Technical Field

[0001] This utility model relates to the technical field of gas probe auxiliary equipment, and in particular to an adjustable gas probe installation device. Background Technology

[0002] In chemical storage facilities, various flammable and explosive chemicals or materials are stored. These substances may leak and release flammable gases. If these gases accumulate to a certain concentration in the air, they may cause fires or even explosions upon contact with ignition sources or high temperatures. Installing gas detectors in chemical storage facilities is one of the important means of preventing fires and explosions. Existing gas detectors have poor installation stability, often slipping or tilting, and their installation height is not adjustable. However, according to the "GB50493-2019 Design Code for Combustible and Toxic Gas Detection Alarms in Petrochemical Industry," the installation height of combustible gas detectors must be strictly controlled between 0.3 and 0.6 meters.

[0003] Therefore, it is necessary to improve the existing adjustable gas probe installation device. Utility Model Content

By setting a circumferential limiting protrusion at the extension end of the support rod, and having a first arc-shaped connecting section of the main fixing member in concave-convex cooperation with it, the installation stability of the gas probe is improved and the gas probe is prevented from tilting. The installation height of the gas probe can also be flexibly adjusted.

[0014] A preferred technical solution is that the first arc-shaped connecting segment is provided with a convex strip and / or a protrusion, the convex strip is oriented toward the interval between adjacent circumferential limiting protrusions, and the circumferential limiting protrusions are provided with limiting holes that correspond one-to-one with the protrusions and fit in a concave-convex manner on their circumferential sides.

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0027] like Figures 1-2As shown, the adjustable gas probe mounting device includes a base 1, a probe limiting member 3, and a main fixing member 4. The base 1 is provided with a support rod 2 perpendicular to its base surface 100. The probe limiting member 3, perpendicular to the support rod 2, has a mounting end 31 and a fixing end 32. The main fixing member 4 is used to connect the support rod 2 and the probe limiting member 3, and includes a first side section 41 and a first arc-shaped connecting section 40 sandwiched between the first side sections 41. The extension end 21 of the support rod 2 is provided with a plurality of circumferential limiting protrusions 20 arranged sequentially along the extension direction, with adjacent circumferential limiting protrusions 20 spaced apart. The first arc-shaped connecting section 40 is sleeved on the periphery of the circumferential limiting protrusions 20 and engages with them. The first side section 41 is connected to the fixing end 32, and the fixing end 32 abuts against the side wall of the extension end 21. The base 1 is bolted to the ground or other mounting objects through mounting holes 10.

[0028] A circumferential limiting protrusion 20 is provided at the extension end 21 of the support rod 2, and the first arc-shaped connecting section 40 of the main fixing member 4 is provided in a concave-convex fit with it. This not only improves the connection between the probe limiting member 3 and the support rod 2, thereby improving the installation stability of the gas probe, but also ensures the stability of the probe limiting member 3, thereby preventing the gas probe from tilting; and the installation height of the gas probe can be flexibly adjusted.

[0029] To simplify the structure of the probe limiting component 3, the mounting end 31 is provided with a mounting through hole 30, the extension direction of which is consistent with the extension direction of the support rod 2. A conventional gas probe is provided with a mounting head, which protrudes radially from its sidewall for easy installation. The mounting head and the mounting through hole 30 on the mounting end 31 are interlocked. Furthermore, the wall of the mounting through hole 30 is provided with at least one threaded through hole 301, extending along the diameter of the mounting through hole 30, for threaded engagement with a tightening screw (not shown). This not only improves the connection strength between the gas probe and the probe limiting component 3 but also adapts to gas probes with mounting heads of different diameters. To further improve the connection strength between the gas probe and the probe limiting component 3, the inner wall of the mounting through hole 30 is provided with an elastic layer (not shown) that adheres to it. The material of this elastic layer includes, but is not limited to, rubber.

[0030] In order to facilitate the installation, connection or disassembly and replacement of the main fixing part 4 and the support rod 2, and at the same time ensure that the contact area of ​​the connection part between the main fixing part 4 and the support rod 2 is larger, thereby improving the connection stability between the two, the inner diameter of the first arc-shaped connecting section 40 is equal to the outer diameter of the circumferential limiting protrusion 20, and the arc length corresponding to the inner diameter of the first arc-shaped connecting section 40 is equal to half the circumference of the circumferential limiting protrusion 20.

[0031] To achieve a proper fit between the first arc-shaped connecting section 40 and the circumferential limiting protrusion 20, improving the connection stability and ensuring the overall stability of the gas probe to prevent tilting, the first arc-shaped connecting section 40 is provided with a protrusion 401 and / or a protrusion (not shown). The protrusion 401 faces the gap between adjacent circumferential limiting protrusions 20, and the circumferential limiting protrusion 20 has limiting holes (not shown) that correspond one-to-one with the protrusions and fit in a proper fit. The cross-section of the protrusion can be any geometric shape. To facilitate the disassembly and replacement of the main fixing component 4, the protrusions are arranged in single groups along the extension direction of the support rod 2.

[0032] To ensure that the probe limiting component 3 remains horizontal, and to enhance support and stability and resist interference from severe weather, the device also includes an auxiliary fixing component 5. The second side section 52 of the auxiliary fixing component 5 is connected to a diagonal support base 50. The diagonal support base 50 is provided with a diagonal support component 51. One end of the diagonal support component 51 is connected to the rotating shaft of the diagonal support base 50, and the other end abuts against the bottom limiting groove 33 of the probe limiting component 3.

[0033] In order to optimize the structure of the main fixing component and the auxiliary fixing component and give full play to the role of the connecting support rod and the probe limiting component, the end faces of the first side section 41 and the second side section 52 are provided with connecting screws 42. The connecting screws 42 extend toward the mounting end 31. The fixing end 32 of the probe limiting component 3 and the inclined support base 50 are both provided with first through holes 320 corresponding to the connecting screws 42. The connecting screws 42 are threadedly engaged with the nuts (not shown).

[0034] The base 1 is also provided with a limiting strip 6 connecting the main fixing component and the auxiliary fixing component. The limiting strip 6 is provided with a second through hole 60 corresponding to the connecting screw 42. The limiting strip 6 is clamped between the fixed end 32 and the inclined support base 50 and the end face (not marked), or the fixed end 32 and the inclined support base 50 are clamped between the limiting strip 6 and the end face. Through the principle of triangular stability, the connection stability between the main fixing component 4, the support rod 2 and the probe limiting component 3 is further improved. Through the Pythagorean theorem, even if the installation position of the main fixing component 4 is changed along the extension direction of the support rod 2, and the installation height of the gas probe is adjusted, the limiting strip 6 limits the relative position between the auxiliary fixing component 5 and the main fixing component 4, ensuring that the inclined support component 51 and the bottom limiting groove 33 of the probe limiting component 3 always abut against each other, playing a role in strengthening the support.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
