Referring to fig. 1 and 2, an embodiment of the present application provides a device 100 for detecting the waterproof performance of a lamp. The lamp waterproof property detection device 100 comprises a water storage tank 10, a sealing plate 20, a control valve 30, a vacuumizing mechanism 40 and a pressurizing mechanism 50.

The water storage tank 10 includes a tank body 11 and a lid body 12, the tank body 11 having an opening, the lid body 12 being for opening and closing the opening of the tank body 11. When the cover 12 is covered on the can 11, the cover 12 and the can 11 together form the accommodating chamber 13. The sealing plate 20 is arranged in the tank 11 through the opening, the accommodating cavity 13 can be divided into a water storage cavity 131 and a gas storage cavity 132, the water storage cavity 131 is arranged far away from the cover 12 relative to the gas storage cavity 132, and the water storage cavity 131 is used for placing a lamp. The sealing plate 20 is movable in the height direction within the can 11, i.e., when the sealing plate 20 is subjected to a force, it is movable in the height direction relative to the can 11.

The sealing plate 20 is provided with a communication port (not shown in the figure) for communicating the water storage chamber 131 with the air storage chamber 132, and the control valve 30 is arranged on the sealing plate 20 to control the opening and closing of the communication port.

Wherein, when the vacuumizing mechanism 40 works, the control valve 30 opens the communication port, so that the gas in the water storage cavity 131 is pumped out through the communication port; when the pressurizing mechanism 50 is operated, the control valve 30 closes the communication port, so that the sealing plate 20 moves relative to the tank 11 under the action of the pressurizing mechanism 50 to pressurize the gas in the water storage chamber 131.

In the lamp waterproof property detection device 100, when the lamp is detected by positive pressure, water is introduced into the water storage cavity 131, then the lamp is placed into the water storage cavity 131, the sealing plate 20 is placed into the tank 11 through the opening, the cover 12 is covered, and the control valve 30 controls the communication port to be closed. The pressurizing mechanism 50 applies a force to the sealing plate 20 such that the sealing plate 20 moves within the tank 11 to pressurize the gas located within the water storage chamber 131. Observing whether water enters the lamp, if so, judging that the waterproof performance of the lamp is not qualified; if no water enters the lamp, the waterproof performance of the lamp is proved to be qualified. When the lamp is subjected to negative pressure test, water is introduced into the water storage cavity 131, then the lamp is placed into the water storage cavity 131, the sealing plate 20 is placed into the tank 11 through the opening, the cover 12 is covered, and the control valve 30 controls the opening of the communication port. The vacuumizing mechanism 40 draws the gas in the gas storage chamber 132 and the gas storage chamber 131, so that the gas storage chamber 131 is maintained in a vacuum state. Observing whether bubbles are generated around the lamp, and if so, judging that the waterproof performance of the lamp is unqualified; if no bubbles are generated around the lamp, the waterproof performance of the lamp is proved to be qualified.

The lamp waterproof property detection device 100 provided by the embodiment of the application not only can detect positive pressure waterproof property of a lamp, but also can detect negative pressure waterproof property, and can simply and rapidly detect the waterproof property of the lamp with different sealing modes, so that the detection cost is reduced.

Further, the lamp waterproof performance detection device 100 further includes an operation panel 70, and corresponding operations are input through the operation panel 70, so that the controller controls the vacuum pumping mechanism 40, the control valve 30 and the pressurizing mechanism 50 to work.

Although the lamp waterproof property detection device 100 can detect the positive pressure waterproof property and the negative pressure waterproof property of the lamp, the lamp waterproof property detection device may be used for positive pressure detection or negative pressure detection, or may be used for only one of them, and is not limited thereto.

In some embodiments, referring to fig. 3 and 4, the tank 11 is provided with a plurality of spaced clamping portions 60, and the clamping portions 60 can clamp the cover 12, so that the cover 12 is fixed on the tank 11, so as to avoid the cover 12 from being separated from the tank 11 when the gas in the water storage cavity 131 is pressurized.

Further, in order to ensure the tightness of the cover 12, the waterproof shape detection device of the lamp further comprises a second sealing ring, and the second sealing ring is arranged between the cover 12 and the tank 11.

The driving member 51 is used for driving the driving rod 52 to move relative to the cover 12, so that the sealing plate 20 moves relative to the tank 11 to pressurize the gas in the water storage chamber 131. Specifically, in order to ensure the sealing effect of the sealing plate 20, water is prevented from overflowing from the water storage cavity 131 through the gap between the sealing plate 20 and the tank 11 when the sealing plate 20 moves relative to the tank 11, and the lamp waterproof property detection device 100 further comprises a first sealing ring, wherein the first sealing ring is arranged between the sealing plate 20 and the tank 11 in a sealing manner.

In other embodiments, the cover 12 is provided with a vent, and the pressurizing mechanism 50 is a compressed gas generating mechanism, and the compressed gas generating mechanism introduces compressed gas into the gas storage chamber 132 through the vent, so that the sealing plate 20 moves relative to the tank 11 to pressurize the gas in the gas storage chamber 131. Thus, when the gas in the gas storage cavity 132 needs to be pressurized, the compressed gas generating mechanism introduces compressed gas into the gas storage cavity 132 through the air vent, and under the action of the compressed gas, the sealing plate 20 moves in the tank 11 to pressurize the gas in the gas storage cavity 132.

Further, in order to detect the pressure of the gas in the gas storage chamber 132, the lamp waterproofing property detection device 100 further includes a pressure sensor.
