Description

A dustproof housing for remote sensing check out test set

Technical Field

The utility model relates to a remote sensing check out test set technical field, concretely relates to dustproof housing for remote sensing check out test set.

Background

In recent years, with the release of the remote sensing detection method standard by the ministry of environmental protection, remote sensing detection formally enters legal procedures, and tail gas remote sensing detection equipment is widely accepted by the market and has also obtained great development opportunities. As shown in fig. 1, in the conventional remote exhaust gas detection device, a collector such as a lens unit 1 and a reflection unit 2 is used to collect energy radiated by a ground object such as exhaust gas, a laser beam expander 3 is used as a light emitting source of a detector, a photoelectric detection technology is used, a scanning imaging type sensor is used to acquire two-dimensional images in a time sequence manner point by point and line by line, signals collected by a processor 8 are processed, and the acquired data are output through a connected output device. A current tail gas remote sensing check out test set assembles a quick-witted case 4 outside collector, detector and treater 8, quick-witted case 4 is a casing, and casing 4 is a sealed housing encapsulation battery of lens group 1, speculum group 2 and laser beam expander 3's front end at battery of lens 1, speculum group 2 and laser beam expander 3, and reserves perspective window, and quick-witted case 4 sets the apron at lens unit 1, the rear end of speculum group 2 and laser beam expander 3, provides the condition for the maintenance of collector and detector, also can tentatively prevent dust to tail gas remote sensing check out test set.

However, the tail gas remote sensing detection equipment needs straight-face tail gas, and in the field use process, because the straight-face tail gas is used on the roadside for a long time, the environment where the tail gas remote sensing detection equipment is located is more because of the particulate matter of raise dust, the particulate matter of raise dust can enter the equipment through the gap of machine case 4, and because the lens is 45-degree inclined installation, easy deposition results in the weakening of received light energy, the measuring result is influenced, and then the maintenance and overhaul frequency of the remote sensing detection equipment is increased, and the maintenance cost is increased.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a cooperation is installed on quick-witted case, can prevent effectively that the dust from adhering to the lens, can increase lens life, reduces the plant maintenance flat road, and does not influence the dustproof housing of the maintenance and the change of laser instrument.

In order to achieve the above object, the utility model discloses a dustproof housing for remote sensing detection equipment, including remote sensing detection equipment's quick-witted case, still include dustproof housing, dustproof housing be connected with quick-witted case and with the quick-witted case is isolated lens unit and reflection unit and external contact jointly, dustproof housing tip respectively with quick-witted case detachably sealing connection.

Furthermore, the dustproof cover shell is connected with the case by dustproof cotton, and the dustproof cotton is fixed and compressed by a plurality of screws to achieve a good dustproof effect.

Furthermore, a U-shaped groove is formed in the position, where the dust-proof housing is installed, of the remote sensing detection device and the laser beam expander, and a U-shaped sealing strip is arranged on the U-shaped groove.

Further, the U-shaped sealing strip is a U-shaped rubber strip.

Compared with the prior art, the beneficial effects of the utility model are that: the dustproof cover shell is selected to be matched with the case in the existing design, and dustproof cotton is compressed between the connection parts of the dustproof cover shell and the case to achieve a better dustproof effect and is fixed and compressed through screws; set up U type groove on dustproof housing to expose laser beam expanding lens, the maintenance and the change of the laser beam expanding lens of being convenient for, and utilize the sealed dustproof of U type rubber strip.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Example 1

As shown in fig. 2-3, the utility model discloses a dustproof housing for remote sensing detection equipment, including remote sensing detection equipment's quick-witted case, be connected with quick-witted case 4 and with machine case 4 forms the dustproof housing 5 of isolated lens unit 1 and

reflection unit

2, 5 tip of dustproof housing respectively with quick-witted case 4 detachably sealing connection. The utility model discloses in, on current quick-witted case 4's basis, cooperation machine case 4 has set up the dustproof housing 5 that can dismantle sealing connection, can further separate deposition such as dust at lens unit 1 and reflection unit 2, can effectively avoid influencing the lens and receive light energy and influence measuring result.

The dustproof housing 5 is detachably and hermetically connected with the case 4 at the connecting part by using the dustproof cotton 6, and is fixed by a plurality of screws and tightly presses the dustproof cotton 6 to achieve a good dustproof effect.

And a U-shaped groove is formed in the mounting position of the dust-proof housing 5 and the laser beam expander 3 of the remote sensing detection equipment, and a U-shaped rubber strip 7 is arranged in the U-shaped groove.

The utility model discloses in, for the change to laser beam expanding lens 3 of being convenient for, the protrusion is reserved through the U type groove that dustproof housing 5 set up to laser beam expanding lens 3, and the change of the laser beam expanding device of being convenient for seals dustproof through U type rubber strip 7 simultaneously.

The utility model discloses, to the not enough of dustproof effect of remote sensing check out test set among the prior art, set up dustproof housing 5 and carry out the secondary dustproof, prevent effectively that the dust from adhering to on the lens, increased the life of lens, reduced the maintenance frequency of lens simultaneously; in addition, the design in U type groove does not influence the change and the maintenance of laser beam expanding lens, satisfies dustproof demand and convenient user demand.
