Description
Technical Field
The utility model relates to a gaseous detection area, concretely relates to gaseous sensor protective structure that detects.
Background
The sensor of the gas detector must be in communication with the external environment, and therefore, the sensor is extremely susceptible to the external environment. The sensor may be affected or even damaged by the faster air flow, rain, etc.
Most gaseous detection sensor's on the market protective structure all is the integral type design at present, and inconvenient dismantlement during the sensor trouble is connected complicacy to calibration equipment when gaseous sensor marks, perhaps cushions the air chamber design alone in order to reduce the impact of very fast air current to the sensor.
Disclosure of Invention
For solving the problem that exists, the utility model provides a gaseous detection sensor protective structure who conveniently dismantles with gaseous detection sensor subassembly.
The technical scheme of the utility model is that: the utility model provides a gas detection sensor protective structure, includes shield casing, filter element and apron, the inside cavity that forms of shield casing, filter element passes through the apron with shield casing fixed connection, the shield casing is equipped with the internal thread.
Preferably, one end of the protective cover shell faces the cavity direction to form a concave part.
Preferably, the recess is provided with a first vent hole, and the first vent hole is communicated with the cavity.
Preferably, the filter member is placed in the recess.
Preferably, the filter part is a metal filter screen or a waterproof and breathable film.
Preferably, the cover plate is provided with a second vent hole, and the second vent hole and the first vent hole are concentric circles.
Preferably, the cover plate is provided with a threaded hole.
Preferably, the concave part of the protective cover shell is correspondingly provided with a threaded hole.
Preferably, the cover plate and the shield shell are fixedly connected through screws.
The utility model has the advantages that: the concave design of the protective cover shell effectively prevents rainwater from entering the gas detection sensor to interfere or damage the sensor, and the filtering component can also filter part of large-particle-size particles and water vapor in the gas to be detected; a gas detection buffer gas chamber is formed in a cavity inside the protective cover shell, so that the damage to the sensor caused by direct entering of external violent gas flow is avoided; gaseous detection sensor protective structure can dismantle with gaseous detection sensor subassembly and be connected, change or the maintenance to the sensor when making things convenient for the sensor trouble to when needs are calibrated gaseous detection sensor, dismantle this gaseous detection sensor protective structure and can conveniently be connected gaseous calibration device and gaseous detection sensor.
Drawings
Fig. 1 is an explosion schematic diagram of the gas detection sensor protection structure of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
As shown in fig. 1, as an embodiment of the utility model, the utility model provides a gas detection sensor protective structure, including shield casing 1, filter element 2 and apron 3, the inside cavity that forms of shield casing 1, filter element 2 passes through apron 3 with shield casing 1 fixed connection, shield casing 1 is equipped with the internal thread.
In a preferred embodiment, a concave portion is formed at one end of the shield case 1 facing the cavity, the concave portion is provided with a first vent hole, the first vent hole is communicated with the cavity, the filter element 2 is placed in the concave portion, the filter element 2 is a metal filter screen or a waterproof breathable film, the cover plate 3 is provided with a second vent hole, the second vent hole and the first vent hole are concentric circles, the cover plate 3 is provided with a threaded hole, the concave portion of the shield case 1 is correspondingly provided with a threaded hole, and the cover plate 3 is fixedly connected with the shield case 1 through a screw.
The sunken design of shield casing 1 has effectively avoided rainwater sputter to get into gaseous detection sensor and cause interference or damage to the sensor, and filter unit 2 also can filter some big particle diameter particulate matter and the aqueous vapor in the gas that awaits measuring.
The cavity in the protective cover shell 1 forms a gas detection buffer air chamber, and damage to the sensor caused by direct entering of external violent airflow is avoided.
Gaseous detection sensor protective structure can dismantle with gaseous detection sensor subassembly and be connected, change or the maintenance to the sensor when making things convenient for the sensor trouble to when needs are calibrated gaseous detection sensor, dismantle this gaseous detection sensor protective structure and can conveniently be connected gaseous calibration device and gaseous detection sensor.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the present invention.
