[0040] Embodiment 1

[0041] This embodiment provides a test box drainage device, such as Figure 1-Figure 2 As shown, the test box drainage device includes a sump 100, a drainage pump 200, a water collecting tank 300 and a first liquid level detection component 400. The sump 100 is used to collect condensed water discharged from the test box. One end of the drainage pump 200 is connected to the water outlet of the sump 100, and the other end is connected to the water inlet of the water collecting tank 300. The first liquid level detection component 400 is arranged in the sump 100 and is communicatively connected with the drainage pump 200. The first liquid level detection component 400 is used to detect the liquid level in the sump 100. When the liquid level in the sump 100 reaches a preset height, the drainage pump 200 is started, and the drainage pump 200 transports the condensed water in the sump 100 to the water collecting tank 300. There is no need to set a floor drain or lay a long drainage pipe at the installation site, which avoids excavation and damage to the ground, and maintains the flatness and overall aesthetics of the ground at the installation site, thereby simplifying the installation process of the test box drainage device, reducing the complexity of construction, and saving installation costs.

[0042] Optionally, the test box drainage device in this embodiment includes a controller, and the first liquid level detection component 400 and the drainage pump 200 are respectively connected to the controller for communication. When the liquid level in the sump 100 rises and triggers the first liquid level detection component 400, the first liquid level detection component 400 transmits the liquid level signal to the controller, and the controller starts the drainage pump 200 to drain the water in the sump 100 into the water collecting tank 300. The drainage pump 200 starts and stops after a preset time, completing the drainage work.

[0043] It should be noted that the controller can be a centralized or distributed controller. For example, the controller can be a single microcontroller or a distributed plurality of microcontrollers. The microcontroller can run a control program. The specific control program is a mature technical means in this field and will not be elaborated here.

[0044] Alternatively, if Figure 2 As shown, the test box drainage device also includes an alarm component, which includes a second liquid level detection component 520 and an audible and visual alarm component 510. The second liquid level detection component 520 is arranged in the water collecting tank 300. The second liquid level detection component 520 is used to detect the liquid level in the water collecting tank 300. The second liquid level detection component 520 and the audible and visual alarm component 510 are respectively communicated with the controller. When the liquid level in the water collecting tank 300 triggers the second liquid level detection component 520, the controller activates the audible and visual alarm component 510 to prompt the operator to clean up the condensed water in the water collecting tank 300 in time to prevent the condensed water from overflowing from the water collecting tank 300, thereby ensuring the dryness of the test environment and the normal operation of the equipment.

[0045] Optionally, the second liquid level detection component 520 includes a first detection liquid level and a second detection liquid level, the second detection liquid level is higher than the first detection liquid level, and the liquid level in the water collecting tank 300 is higher than the first detection liquid level, the sound and light alarm component 510 is activated, prompting the operator to clean up the accumulated water in the water collecting tank 300 in time to prevent the water level from further rising and causing overflow; when the liquid level in the water collecting tank 300 is lower than the first detection liquid level, the sound and light alarm component 510 stops, reducing unnecessary alarms; when the liquid level in the water collecting tank 300 reaches the second detection liquid level, the drainage pump 200 stops working to prevent the condensed water in the water collecting tank 300 from overflowing, thereby protecting the test site environment from water immersion and keeping the test environment clean and safe.

[0046] In this embodiment, the second liquid level detection component 520 is set with a first detection liquid level and a second detection liquid level. When the liquid level in the water collecting tank 300 is between the first detection liquid level and the second detection liquid level, the sound and light alarm component 510 is activated, providing the operator with a buffer time for processing, so as to avoid the situation where the water in the water collecting tank 300 has reached a state of overflowing when the sound and light alarm component 510 is activated, thereby improving the reliability and safety of the drainage device of the test box.

[0047] Optionally, the first liquid level detection member 400 and the second liquid level detection member 520 are both float liquid level switches. The float liquid level switch has a simple mechanical structure, a low failure rate, and low maintenance requirements. It can operate stably for a long time, reducing maintenance and replacement costs. By separately setting the first float liquid level switch and the second float liquid level switch, dual liquid level protection can be achieved. Specifically, when the liquid level in the water collection tank 100 reaches a set value, the first float liquid level switch can start the drainage pump 200; and when the liquid level in the water collection tank 300 reaches a set value, the second float liquid level switch can trigger an alarm or stop the drainage pump 200, further improving the safety and reliability of the drainage device of the test box.

[0048] Optionally, the sound and light alarm element 510 is an alarm light, and the flashing of the alarm light provides an intuitive visual signal, so that the operator can quickly identify the water level in the water collecting tank 300 and take corresponding measures in time to prevent condensed water from overflowing from the water collecting tank 300.

[0049] In one embodiment, the sound and light alarm element 510 is a buzzer alarm, which provides a sound alarm so that the operator can promptly know the water level in the water collecting tank 300 even if he does not pay attention to the visual signal, thereby improving the effectiveness and timeliness of the alarm.

[0050] In another embodiment, an alarm light and a buzzer alarm may be provided at the same time to provide a dual alarm mechanism, thereby further improving the reliability of the test chamber drainage device and ensuring that operators can respond in a timely manner to prevent potential overflow risks.

[0051] Optionally, the drainage pump 200 in this embodiment is a diaphragm pump, which can prevent liquid from flowing back when it stops working, protect the drainage system from being affected by liquid backflow, and ensure the safe operation of the drainage device of the test box.

[0052] Optionally, a first drain port 310 is provided at the bottom of the water collecting tank 300, and a drain switch is provided at the first drain port 310. Turning on the drain switch can conveniently drain the condensed water in the water collecting tank 300. Specifically, when draining, a container such as a basin or a bucket is placed at the first drain port 310, and the drain switch is turned on. Optionally, the drain switch can be a ball valve or a faucet.

[0053] Optionally, the volume of the water collecting tank 300 is greater than or equal to twice the volume of the water collecting tank 100, which can reduce the frequency of cleaning the water collecting tank 300. For example, if drainage is performed once or twice a day, the volume of the water collecting tank 100 is 30L, and the volume of the water collecting tank 300 can be 60L, so as to avoid the user repeatedly cleaning the condensed water in the water collecting tank 300. It should be noted that in this embodiment, the volume of the water collecting tank 300 and the volume of the water collecting tank 100 are not specifically limited, and can be adaptively changed according to actual drainage needs.

[0054] Optionally, the test box drainage device further includes a bracket, which is used to support the water collecting box 300 , thereby raising the height of the water collecting box 300 to facilitate the water in the water collecting box 300 to be discharged through the first drainage port 310 at the bottom of the water collecting box 300 .

[0055] Optionally, the test box drainage device further includes a drainage drawer, and a receiving space is provided on the bracket, and the drainage drawer is placed in the receiving space, and the drainage drawer is used to collect condensed water discharged from the water collecting tank 300. By providing a space on the bracket and placing the drainage drawer in the receiving space, the structure of the test box drainage device can be made more compact; the provision of the drainage drawer makes it unnecessary to find other containers when draining water, making the drainage process more convenient.

[0056] Optionally, the height of the water inlet of the water collecting tank 300 is less than or equal to the lift height of the drainage pump 200. The matching of the water inlet height of the water collecting tank 300 and the lift height of the drainage pump 200 prevents damage to the drainage pump 200 and keeps the drainage pump 200 running stably.
