Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, and specifically relates to an automatic detection device for the integrity of a glass ball of a sprinkler nozzle. Background Art

[0002] Most public places need to install glass ball sprinkler heads for fire fighting. The glass ball of the glass ball sprinkler head is filled with liquid, and there is a bubble in the liquid. When a fire occurs, when the temperature rises to the operating temperature of the glass ball, the glass ball breaks, the plug of the glass ball sprinkler head opens and sprays water to extinguish the fire. Therefore, the integrity of the glass ball is related to whether the glass ball sprinkler head can spray water to extinguish the fire in time when a fire occurs. However, there is no equipment in the current production process of glass balls to test the integrity of the glass ball. Sprinkler heads that have not been tested for integrity are directly put into use. If the glass ball of the sprinkler head is not intact, the sprinkler head will not be able to respond in time when a fire occurs or the glass ball will malfunction when there is no fire, which will seriously threaten people's lives and property safety.

[0003] In the prior art, for example, a Chinese patent for a glass ball sprinkler head glass ball integrity test device, with announcement number CN212308722U, effectively tests the integrity of the glass balls by arranging a heating box, an initial shooting device, an experimental shooting device, and a final shooting device on a transmission line. However, the test device has a low degree of automation and does not have a device for screening qualified and unqualified products. The test relies too much on manual labor, which reduces the test efficiency. Utility Model Content

DETAILED DESCRIPTION

[0019] The following describes the specific implementation of the utility model in detail in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the utility model. Although the utility model is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative, rather than limiting the scope of the utility model.

[0020] Specific embodiment 1: Please refer to Figure 1-2 The invention discloses an automatic detection device for the integrity of a sprinkler glass ball, comprising: a base 1 and an inlet imaging component 2, a heating component 3, a high-temperature imaging component 4, a high-temperature rejection component 5, an air-cooling component 6, a normal-temperature imaging component 7, a normal-temperature rejection component 8, a material receiving component 9, a turntable 10, a control box 11, a display 12 and a servo motor installed on the base 1, wherein the output end of the servo motor is connected to the turntable 10, and the servo motor can drive the turntable 10 to rotate at a certain speed when working, and the inlet imaging component 2, the heating component 3, the high-temperature imaging component 4 , high temperature rejection component 5, air cooling component 6, normal temperature imaging component 7, normal temperature rejection component 8, and material receiving component 9 are arranged in sequence in a counterclockwise direction around the axis of the turntable 10. In addition, a controller is provided in the control box 11. The controller is connected to the inlet imaging component 2, the heating component 3, the high temperature imaging component 4, the high temperature rejection component 5, the air cooling component 6, the normal temperature imaging component 7, the normal temperature rejection component 8, the material receiving component 9, the display 12 and the servo motor through circuits. The controller can control the components to work together to improve the efficiency of the integrity test of the glass balls.

[0021] Specifically, the entrance imaging component 2, high temperature imaging component 4, and normal temperature imaging component 7 have the same structure. Taking the entrance imaging component 2 as an example, the entrance imaging component 2 includes a mounting frame and a camera. The camera is mounted on the upper side of the turntable 10, and the camera is connected to the controller through a circuit.

[0022] The high temperature rejection component 5, the normal temperature rejection component 8 and the material receiving component 9 have the same structure. Taking the high temperature rejection component 5 as an example, the high temperature rejection component 5 includes a mounting frame and a push rod cylinder. The push rod cylinder is mounted on the upper side of the turntable 10 through the mounting frame. At the same time, the push rod cylinder is connected to the controller through a circuit.

[0023] The heating component 3 is composed of a fan, a heater and an air duct. The fan can transport the high-temperature gas generated by the heater into the air duct. The air duct is at least partially arranged on the turntable 10. The air duct at the corresponding position of the turntable 10 is also provided with an inlet 31 and an outlet 32. The stroke between the inlet 31 and the outlet 32 ​​can at least cover one-third of the turntable 10. During the test, the sprinkler head is placed on the turntable 10. Driven by the servo motor, the sprinkler head enters the air duct from the inlet 31 as the turntable 10 rotates, and then exits the air duct from the outlet 32 ​​after being heated. Sufficient stroke can make the sprinkler head entering the air duct fully heated to reach a predetermined temperature, thereby improving the test efficiency.

[0024] A plurality of slots are provided at the upper end of the turntable 10, the sizes of which match the sizes of the sprinkler heads, and the slots are evenly distributed around the axis of the turntable 10; the provision of the slots not only allows the sprinkler heads placed on the turntable 10 to be more stable, but also provides operators with accurate placement positions, which can improve test efficiency; further, the slots are U-shaped slots opening outward, and the opening outward can guide the removal action of the removed parts, which is convenient for the recovery or collection of the sprinkler heads.

[0025] In this embodiment, the material discharging area is between the material receiving component 9 and the inlet imaging component 2. During the test, the sprinkler head is manually placed on the card slot of the turntable 10, and the turntable is rotated by the servo motor to drive the sprinkler head to rotate. The size of the bubble of the glass ball of the sprinkler head at room temperature is recorded through the inlet imaging component 2. The sprinkler head continues to rotate to pass through the air duct with a specific temperature, so that the temperature of the glass ball of the sprinkler head reaches a predetermined value. The high-temperature imaging component 4 records the size of the bubble of the glass ball after the air duct is discharged. The software of the controller analyzes the data changes between the high-temperature imaging component 4 and the inlet imaging component 2, and the data that does not meet the standard is kicked out by the high-temperature rejection component 5. The qualified nozzles will continue to flow to the air-cooling component 6, which will work to reduce the temperature of the glass ball of the sprinkler nozzle to room temperature, and then flow to the room-temperature imaging component 7. The room-temperature imaging component 7 records the size of the glass ball bubbles. The controller compares the data of the room-temperature imaging component 7 with the data of the high-temperature imaging component 4. The bubbles in the glass ball under room temperature conditions should be restored to their original state. If not, they will be kicked out by the room-temperature rejection component 8. The remaining nozzles are all qualified products. When the qualified products move to the receiving component 9, the qualified sprinkler nozzles are kicked out of the detection equipment by the receiving component 9 and flow to the unloading station, and the whole detection process is completed.

[0026] In summary, by installing the inlet imaging component, heating component, high-temperature imaging component, high-temperature rejection component, air-cooling component, normal temperature imaging component, normal temperature rejection component, material receiving component, turntable, control box, display and servo motor and other components on the base, when the sprinkler heads are tested, the detection equipment can automatically screen unqualified and qualified sprinkler heads, thereby reducing labor effort and improving test efficiency.
