[0003] After checking the announcement number: CN212568696U, a multi-component gas detection and analysis device is disclosed, which includes a protective shell, a conductive tube is fixedly installed on the upper end of the inner side of the protective shell, a connecting sleeve is fixedly installed on the upper end of the protective shell, both sides of the connecting sleeve are provided with jacks, a limited square groove is provided on one side of the lower end of the jack, an adjustment column is slidably connected to the inner side of the jack, the lower end of the adjustment column is movably connected to the connecting column, the upper end of the adjustment column is fixedly installed with a support plate, one side of the support plate is fixedly installed with a connecting disk, and the upper end of the connecting disk is movably connected with a filter disk. The utility model detects gas entering through the ventilation sleeve, and the gas filters dust through the filter disk, so that the device has protective measures, which increases the service life of the device. When the ventilation sleeve needs to be replaced, when the support plate is lifted, the connecting disk will be pulled up at the same time, and the connecting disk drives the filter disk to move out of the inner side of the connecting sleeve, which is convenient for replacing the filter disk and ensuring the normal operation of the filter disk, making the device easy to use.

[0004] The filter plate is set at the air inlet of the gas detector to filter the dust in the gas and protect the gas detector to a certain extent. However, it is mainly used by hand during operation, and the detection range is limited. When it is necessary to detect the gas composition at a high altitude, the staff needs to use climbing equipment, which is cumbersome, time-consuming and laborious. Therefore, we propose a visual gas composition detection device to solve the above problems. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Please refer to Figure 1-6 The utility model provides a technical solution: a visual gas component detection device, comprising a gas detector 1, a multi-stage telescopic rod 14, a gas guide hose 14 is arranged on the air inlet of the gas detector 1, a mounting bracket 5 is fixedly installed on the back of the gas detector 1, and a winding roller 6 is movably installed inside the mounting bracket 5, and a gas guide hose 12 is wound around the outside of the winding roller 6. Through the gas guide hose 12, the gas at a high place can be introduced into the gas detector 1, so as to realize the suction detection of the gas at a high place and expand the detection range, and one end of the gas guide hose 12 is connected with the gas guide hose 14, and the other end is fixedly connected with the mounting hard pipe 13, and one end of the winding roller 6 is fixedly sleeved with an adjusting disk 10 , and a locking mechanism 9 is provided on the adjusting disk 10. When gas detection is performed, the gas hose 12 can be pulled to expand the detection range. After the detection, the gas hose 12 is reeled up by the reeling roller 6 to prevent the gas hose 12 from being scattered. At the same time, the reeling roller 6 is locked by the locking mechanism 9 and the locking hole 11. A plurality of locking holes 11 cooperating with the locking mechanism 9 are opened at one end of the mounting bracket 5 close to the adjusting disk 10. A plurality of elastic clips 15 cooperating with the mounting hard pipe 13 are fixedly sleeved at the end of the multi-stage telescopic rod 14. The mounting hard pipe 13 is clamped by the elastic clip 15 to ensure that the multi-stage telescopic rod 14 can drive the mounting hard pipe 13 to move synchronously, thereby realizing the suction detection of high-altitude gas.

[0026] As a further implementation scheme of the above technical scheme: a connecting elbow 7 is embedded in the end of the winding roller 6 away from the adjusting disk 10, and one end of the connecting elbow 7 is fixedly connected to the air guide hose 2 12, and the other end is fixedly connected to the rotary joint 8. When the winding roller 6 rotates, the connecting elbow 7 and the rotary joint 8 are used for conduction to ensure that the air guide hose 1 4 and the air guide hose 2 12 are still in a connected state, thereby ensuring the smooth flow of the air path, and at the same time the winding roller 6 can be rotated to retract and release the air guide hose 2 12.

[0027] As a further implementation scheme of the above technical scheme: the rotary joint 8 is located on the central axis of the winding roller 6, and the end of the rotary joint 8 away from the connecting elbow 7 is fixedly connected to the gas hose 4, and the position of the rotary joint 8 is restricted to ensure that when the winding roller 6 rotates, the gas hose 4 and the gas hose 2 12 are still in a connected state. The gas hose 14 is connected to the gas hose 2 12 through the rotary joint 8 and the connecting elbow 7. The gas sucked in the gas hose 2 12 can be introduced into the gas hose 4 through the rotary joint 8 and the connecting elbow 7, and then the gas enters the gas detector 1 for detection.

[0028] As a further implementation plan of the above technical scheme: the locking mechanism 9 includes a locking rod 91, a compression spring 92 and a limit plate 93. When the winding roller 6 winds up the air guide hose 12, the adjusting disk 10 and the winding roller 6 can be locked by the locking mechanism 9 to ensure the stability of the air guide hose 12 after winding. The locking mechanism 9 is movably installed on the adjusting disk 10, and the outer movably sleeve of the locking rod 91 is provided with a compression spring 92. The outer fixed sleeve of the locking rod 91 is provided with a limit plate 93, and the limit plate 93 is clamped on the outer end surface of the adjusting disk 10. The locking rod 91 is pulled to move outward. When the limit plate 93 is completely separated from the adjusting disk 10, the locking rod 91 is rotated ninety degrees so that the locking rod 91 is clamped on the end of the adjusting disk 10, and the locking mechanism 9 is released from the winding roller 6, which is convenient for stretching the air guide hose 12.

[0029] As a further implementation plan of the above technical solution: the compression spring 92 is located between the adjusting disk 10 and the mounting bracket 5, and the compression spring 92 can continuously apply elastic force to the locking rod 91. The end of the locking rod 91 can be inserted into the locking hole 11 under the elastic force of the compression spring 92. After the winding roller 6 winds up the air guide hose 12, the compression spring 92 applies elastic force to the locking rod 91, so that the end of the locking rod 91 is clamped into the locking hole 11 at the corresponding position, so as to lock the adjusting disk 10 and the winding roller 6 and prevent the air guide hose 12 from becoming scattered.

[0030] As a further implementation scheme of the above technical scheme: a positioning ring cooperating with the elastic clip 15 is arranged on the outside of the installation hard tube 13, and the installation hard tube 13 is restricted by the positioning ring to ensure the stability of the installation hard tube 13 after being clamped in the elastic clip 15. The installation hard tube 13 is clamped at the end of the multi-stage telescopic rod 14 by the elastic clip 15. The installation hard tube 13 is clamped by the elastic clip 15 to ensure that the multi-stage telescopic rod 14 can drive the installation hard tube 13 to move synchronously, thereby realizing the suction detection of high-altitude gas.

[0031] As a further implementation scheme of the above technical scheme: one end of the gas guide hose 4 close to the air inlet of the gas detector 1 is fixedly connected with a connector 2, and the air inlet of the gas detector 1 is provided with a threaded tube that cooperates with the connector 2. The connector 2 is threadedly connected to the air inlet of the gas detector 1 to facilitate cleaning and replacement of the filter disc 3. The filter disc 3 is clamped inside the connector 2. When detecting the gas composition, impurities such as dust in the gas can be filtered through the filter disc 3 to prevent the impurities from affecting the gas detector 1.

[0032] Working principle:

[0033] When using the utility model, the gas detector 1 sucks the gas along the connecting head 2, the gas hose 1 4, the connecting elbow 7, the gas hose 2 12 and the installation hard pipe 13 during operation to detect the gas composition, and displays the detection data through the display screen of the gas detector 1. At the same time, when the gas enters the gas detector 1, the dust and other impurities in the gas are filtered through the filter disc 3 to prevent the impurities from affecting the gas detector 1. The connecting head 2 is unscrewed along the air inlet of the gas detector 1, and the filter disc 3 can be cleaned or replaced; when detecting the gas at a high altitude, the locking rod 91 is pulled to move outward. When the limit plug plate 93 is completely separated from the adjusting disk 10, the locking rod 91 is rotated ninety degrees so that the locking rod 91 is clamped at the end of the adjusting disk 10, the locking mechanism 9 is released from the lock of the winding roller 6, and the gas hose 2 12 is pulled to the required length as needed. The gas hose 14 is connected to the gas hose 2 12 through the rotary joint 8 and the connecting elbow 7. When the winding roller 6 rotates, it is ensured that the gas hose 14 and the gas hose 2 12 are still in a connected state. The multi-stage telescopic rod 14 is extended according to the detection height. The multi-stage telescopic rod 14 is held and drives the installation hard pipe 13 to move. The installation hard pipe 13 is moved to the detection height to realize the suction detection of high-altitude gas and expand the detection range of the gas detector 1; after the gas component is detected, the winding roller 6 is driven to rotate by the adjusting disk 10 to rewind and reset the gas hose 2 12 to prevent the gas hose 2 12 from being scattered. When the adjusting disk 10 rotates the winding roller 6 into place, the rotating locking rod 91 drives the limit plug plate 93 to rotate and reset, and the elastic force is applied to the locking rod 91 by the compression spring 92, so that the end of the locking rod 91 is clamped in the corresponding locking hole 11, and the adjusting disk 10 and the winding roller 6 are locked.
