[0001] The utility model relates to the technical field of condensate drainage of air conditioner cabinets, and particularly relates to a condensate drainage device for an anti-static direct current room air conditioner cabinet. Background Technique

[0002] In an anti-static direct current room, numerous rectifying devices and inverter devices operate continuously, generating a large amount of heat. If the temperature is not reduced in time, the devices will have a high failure rate when operating at high temperature for a long time, seriously affecting the reliability of the direct current system and indirectly affecting the reliable operation of the protection devices of the power system. Using the refrigeration function of a cabinet air conditioner to control the temperature in the anti-static direct current room within a certain temperature range has become the most effective way. However, when the cabinet air conditioner leaks water and is not dealt with in time, it will be long-term, seeping through the gaps in the anti-static floor to the lower part of the floor. When the seepage affects the insulation of the direct current cables used by the power system protection devices and the cable insulation drops to cause multi-point grounding, it will cause misoperation or refusal to operate of the power system protection devices, resulting in accidents.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only one embodiment of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] To make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] In the following description, references to "an embodiment", "embodiments", "an example", "examples", etc. indicate that the embodiments or examples so described may include specific features, structures, characteristics, properties, elements, or limitations, but not every embodiment or example necessarily includes the specific features, structures, characteristics, properties, elements, or limitations. Additionally, repeated use of the phrase "according to an embodiment of the present application" may, although not necessarily, refer to the same embodiment.

[0020] As Figure 1-2 shown, the present utility model discloses a drainage device for an anti-static direct current room air conditioner cabinet, which includes a water collecting tank 1 and a drainage assembly 2. The water collecting tank 1 is arranged below the air conditioner cabinet for collecting the leaked water of the air conditioner cabinet. The drainage assembly 2 includes a jacket pipe 21, a check valve 22, and a drain pipe 23. The jacket pipe 21 includes an outer pipe 211 and an inner pipe 212, and there is a gap between the outer pipe 211 and the inner pipe 212. The first end of the outer pipe 211 is connected to the side wall of the water collecting tank 1 and is in communication with the water collecting tank 1. The first end of the inner pipe 212 passes through the first end of the outer pipe 211 and is located in the water collecting tank 1 and is in communication with the water collecting tank 1. The port of the second end of the inner pipe 212 is lower than the port of the first end of the inner pipe 212 and higher than the port of the second end of the outer pipe 211. The water inlet of the check valve 22 is in communication with the second end of the outer pipe 211, and the drain pipe 23 is in communication with the water outlet of the check valve 22.

[0021] When the air conditioner cabinet leaks water, the water collecting tank 1 collects all the leaked water generated by the air conditioner cabinet; when the water surface height reaches the port of the first end of the outer pipe 211 of the jacket pipe 21, water enters the outer pipe 211, that is, water enters the gap between the outer pipe 211 and the inner pipe 212. Under the action of the check valve 22, the water surface in the jacket pipe 21 is raised to submerge the port of the second end of the inner pipe 212 in the jacket pipe 21. By adjusting the check valve 22, the water surface height in the jacket pipe 21 is increased until the inner pipe 212 can generate a siphon effect. Then, the check valve 22 is opened, and the leaked water of the air conditioner cabinet collected in the water collecting tank 1 is discharged through the drain pipe 23 by the siphon effect of the inner pipe 212, so as to quickly discharge the leaked water of the air conditioner cabinet in the water collecting tank 1.

[0022] The present utility model collects all the leaked water of the air conditioner cabinet by arranging the water collecting tank 1 and the drainage assembly 2, and at the same time, the leaked water of the air conditioner cabinet in the water collecting tank 1 can be discharged through the siphon effect, preventing the leaked water of the air conditioner cabinet from leaking through the gaps of the anti-static floor to the lower part of the floor, and avoiding the insulation degradation of the DC cables used in the power system protection device, which may cause misoperation or refusal of the protection device and lead to accidents.

[0023] In one embodiment, the inner tube 212 includes a siphon tube 2121 and a connecting tube 2122. The siphon tube 2121 is located in the water collecting tank 1, and the port of the first end is arranged parallel to the bottom surface of the water collecting tank 1. When the water level in the water collecting tank 1 rises to the same height as the port of the first end of the siphon tube 2121, it is convenient for water to enter the siphon tube 2121. The connecting tube 2122 is arranged in the outer tube 211, and its first end is connected to the second end of the siphon tube 2121. This is convenient for staff to use and install. At the same time, by adjusting parameters such as the length and diameter of the siphon tube 2121 and the connecting tube 2122, different drainage requirements and environmental conditions can be flexibly responded to.

[0024] In one embodiment, the distance between the port of the first end of the siphon tube 2121 and the bottom surface of the water collecting tank 1 is 1 mm. As the water level in the water collecting tank 1 continues to rise, the water level in the siphon tube 2121 also rises accordingly, which helps to ensure that the siphon tube 2121 can make full use of the water level difference to start the siphon effect, and at the same time reduces the accumulated water in the water collecting tank 1.

[0025] In one embodiment, it further includes a support base 3 for placing an air-conditioning cabinet. The support base 3 is of a frame structure, and the water collecting tank 1 is installed inside the support base 3. In this embodiment, the support base 3 is made of a metal frame, and its shape is a cube. The length and width dimensions of the top surface are larger than the bottom surface of the air-conditioning cabinet, and a set of diagonal supports are provided, which can place various air-conditioning cabinets smaller than the size of the top surface of the metal frame.

[0026] In one embodiment, the water collecting tank 1 is made of a plastic material. The support base 3 can be used as a support hub for the water collecting tank 1, enhancing the functionality and flexibility of the entire device.

[0027] In one embodiment, an observation hole 4 is opened on the water collecting tank 1, which is convenient for staff to timely discover whether there is water leakage, so as to report for repair in the first time.

[0028] In one embodiment, the check valve 22 is an adjustable resistance check valve 22.

[0029] The working principle of the embodiment of the present utility model is as follows:

[0030] Place various models of air conditioner cabinets smaller than the top size of the support base 3 in the center of the support base 3. When the air conditioner cabinet leaks water, the water collecting tank 1 collects all the leaked water generated by the air conditioner cabinet. When the water level in the water collecting tank 1 rises to the same height as the port of the first end of the siphon pipe 2121, water enters the siphon pipe 2121. As the water level in the water collecting tank 1 continues to rise, the water level in the siphon pipe 2121 also rises accordingly. When the water level reaches the port of the first end of the outer pipe 211 of the jacket pipe 21, water enters the outer pipe 211, that is, water enters the gap between the outer pipe 211 and the inner pipe 212. Under the blocking action of the adjustable resistance check valve 22, the water level in the jacket pipe 21 is raised to submerge the port of the second end of the inner pipe 212 of the jacket pipe 21, that is, to submerge the port of the second end of the connecting pipe 2122. Through the resistance of the adjustable resistance check valve 22, the water level in the jacket pipe 21 is raised until the inner pipe 212 can generate a siphon effect, and then the adjustable resistance check valve 22 can be opened. The leaked water of the air conditioner cabinet collected in the water collecting tank 1 is discharged through the drain pipe 23 by the siphon effect of the inner pipe 212, so as to quickly discharge the leaked water of the air conditioner cabinet in the water collecting tank 1.

[0031] The utility model collects all the leaked water of the air conditioner cabinet by setting the water collecting tank 1 and the drainage component 2. At the same time, the leaked water of the air conditioner cabinet in the water collecting tank 1 can be discharged by the siphon effect, preventing the leaked water of the air conditioner cabinet from leaking through the anti-static floor gap to the lower part of the floor, avoiding the reduction of the insulation of the DC cable used in the power system protection device, and preventing the protection device from malfunctioning or refusing to operate, resulting in accidents.

[0032] The above description of the disclosed embodiments enables those skilled in the art to implement or use the utility model. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the utility model. Therefore, the utility model will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
