[0020] In order to make the above-mentioned purpose, features and advantages of the utility model more apparent and easy to understand, the specific implementation of the utility model is described in detail below with reference to the drawings.

[0021] In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the utility model, but the utility model can also be implemented in other ways different from the description, and those skilled in the art can make similar generalizations without departing from the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0022] Secondly, "one embodiment" or "embodiment" referred to herein can include specific features, structures or characteristics in at least one implementation of the utility model. "In one embodiment" does not refer to the same embodiment, nor is it a separate or alternative embodiment.

[0023] Thirdly, the utility model is described in detail in conjunction with the schematic diagram, and in the detailed description of the utility model embodiments, the cross-sectional view of the device structure is partially enlarged without the general proportion for the convenience of description, and the schematic diagram is only an example, which should not limit the scope of protection of the utility model here. In addition, the three-dimensional spatial dimensions of length, width and depth should be included in actual production.

[0024] REFERENCE Figs. 1-3 For one embodiment of the utility model, a gas turbine intake chamber water automatic drainage device is provided, which comprises "S" shape water seal pipe 1 and two groups of corrugated hoses 2, and the two groups of corrugated hoses 2 are fixedly connected to the pipe bodies on both sides of the water trap of the "S" shape water seal pipe 1 respectively, which is the same as the prior art, and the "S" shape water seal pipe 1 is connected to the bottom of the intake chamber water drainage tank during use, and the shape of "S" is adopted here, so that the communication end with the atmosphere is arranged downward, which can prevent foreign matters from falling into the interior thereof.

[0025] On the outer side of the "S"-shaped water seal pipe 1, between the two end points of the "S"-shaped water seal pipe 1 and the corrugated hose 2, a screw rod 3 is rotatably arranged to adjust the extension and contraction of the two groups of corrugated hoses 2 to control the capacity of the water trap of the "S"-shaped water seal pipe 1. At one end of the screw rod 3, there is a knob-shaped structure for facilitating the rotation of the screw rod 3. The rotation of the screw rod 3 adjusts the extension and contraction of the two groups of corrugated hoses 2, which can adjust the capacity of the water trap of the "S"-shaped water seal pipe 1, that is, the water seal height and the water seal strength of the "S"-shaped water seal pipe 1. According to the actual demand, the problem of water backflow or excessive water seal leading to a significant increase in drainage resistance can be avoided.

[0026] As shown in Figs. 1-3 , between the pipe bodies on both sides of the water trap of the "S"-shaped water seal pipe 1, on the upper and lower sides of the two groups of corrugated hoses 2, fixed plates 4 are fixedly connected. The screw rod 3 is rotatably arranged through one of the fixed plates 4 and threadedly arranged through the other fixed plate 4. When the screw rod 3 is rotated, the distance between the two fixed plates 4 can be adjusted, thereby adjusting the extension and contraction of the two groups of corrugated hoses 2.

[0027] As shown in Figs. 1-3 , two groups of inner sleeves 5 are fixedly connected to one of the fixed plates 4. The two groups of inner sleeves 5 are respectively sleeved on the outer sides of the two groups of corrugated hoses 2. The outer sides of the two groups of inner sleeves 5 are slidably sleeved with outer sleeves 6. The two groups of outer sleeves 6 are fixedly connected to the other fixed plate 4. The two groups of inner sleeves 5 and the two groups of outer sleeves 6 are used to maintain the stability of the device and prevent the two groups of corrugated hoses 2 from being twisted when the screw rod 3 is rotated. At the same time, they can also play a protective role for the two groups of corrugated hoses 2.

[0028] As shown in Fig. 1 , the outer side of the inner sleeve 5 is provided with a scale line in the axial direction. The scale line cooperates with the outer sleeve 6 to reflect the maximum water seal height of the water trap of the "S"-shaped water seal pipe 1 under the current extension and contraction of the two groups of corrugated hoses 2. The scale line is used to more conveniently adjust the device to meet the actual use requirements.

[0029] As shown in Figs. 1-3 , a water level rod 7 for indicating the water level in the "S"-shaped water seal pipe 1 is slidably arranged on the pipe body on the side of the water trap of the "S"-shaped water seal pipe 1 connected to the atmosphere. The end of the water level rod 7 located in the "S"-shaped water seal pipe 1 is fixedly connected with a float 8. The water level rod 7 cooperates with the float 8 to facilitate the operator to judge the actual water seal height in the "S"-shaped water seal pipe 1. On the end of the water level rod 7 away from the float, there is a block-shaped structure for preventing the water level rod 7 from falling into the "S"-shaped water seal pipe 1.

[0030] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
