Description

Technical Field

[0001] The utility model belongs to the field around the smoke sensor of the belt conveyor, and particularly relates to a device for testing whether the smoke sensor at the head of the belt conveyor is normal. Background Art

[0002] The function of the smoke protection device is that when a fire is caused by friction or the like of the belt of the belt conveyor and smoke is generated around and reaches a certain concentration, the protector automatically gives out an audible and visual alarm and automatically cuts off the power supply of the belt conveyor to achieve smoke protection.

[0003] The smoke protection sensor should be installed directly above the upper belt at a position 5 m to 15 m downwind of the head of the belt conveyor, and the distance from the roof should not be greater than 300 mm. The smoke protection should be checked and simulated tested once a day. The replaced sensor should be tested on the ground test bench with smoke to simulate the on-site test, and those with insensitive actions should be repaired in time for standby.

[0004] The smoke sensor at the head of the belt conveyor in a certain mine is only 20 cm from the roof. Every time a test is carried out, personnel need to climb onto the belt rack for the test, which is very troublesome to operate and there is a risk of personnel falling. Content of the Utility Model

[0030] The upper end of the force-bearing rope 12 is fixedly connected to the lower end of the pressing rod 11. The lower end of the force-bearing rope 12 extends downward along the test support rod 10 and is arranged close to the lower end of the test support rod 10.

A conversion hole is formed in the outer end of the conversion rod 13 for the lower end of the force-bearing rope 12 to pass through and extend toward the lower end of the test support rod 10.

[0031] The lower end of the force-bearing rope 12 is used to move downward under an external force, so that the force-bearing rope 12 generates a pulling force perpendicular to the test support rod 10 and away from the test support rod 10 under the action of the conversion rod 13, thereby pulling the lower end of the pressing rod 11 to move in a direction perpendicular to the test support rod 10 and away from the test support rod 10, so that the upper end of the pressing rod 11 moves in a direction perpendicular to the test support rod 10 and close to the test support rod 10, and presses the nozzle of the smoke detection reagent bottle 15 to force the smoke detection reagent bottle 15 to spray the reagent to test the smoke sensor near the top of the roadway.

[0032] The utility model further includes a force control rod 14. The force control rod 14 is located at the lower end of the test support rod 10. The force control rod 14 is composed of an upper support rod 16 and a lower support rod 17. The upper end of the upper support rod 16 is hinged to the test support rod 10.

[0039] The utility model adopts the principle of a lever. The smoke detection reagent bottle 15 is fixed to the upper end of the test support rod 10. By only pressing the control force rod 14, the smoke detection reagent bottle 15 can be pressed through the force-bearing rope 12, and the smoke detection reagent bottle 15 is forced to eject the reagent to test the smoke sensor, which is very convenient. It not only improves the test efficiency of the smoke sensor, but also does not require the test personnel to climb onto the belt rack for testing, ensuring the safety of the test personnel.
