Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation doors for transformer substations, in particular to a sound insulation door device for transformer substations. Background Art

[0002] Electricity is one of the indispensable energy sources in people's lives. With the rapid development of the power sector, the problem of high-voltage power transportation has been gradually solved. One of the indispensable equipment in the power transportation process is the substation. The substation is a place in the power system to transform voltage and current, receive electric energy and distribute electric energy. Only with the existence of substations can electricity be converted between high or low voltage and supplied for use between cities and villages.

[0003] The substation itself is a high-voltage power conversion site. There are a variety of protection measures inside the substation to ensure the safety of power conversion. Among them, the substation's own structure and door body are the most powerful guarantees. The traditional substation door body has multiple sound insulation functions, but because the substation door body needs to be set up with a pressure relief, it is difficult to completely isolate the sound inside the substation door body, resulting in noise pollution. Therefore, it is urgent to design a sound insulation door device for substations to solve the above problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a soundproof door device for a substation. A soundproof sealing plate that can rise and fall with the pressure is provided inside the pressure relief gas chamber inside the soundproof door body. During normal use of the door body, the noise transmitted from the pressure relief gas chamber can be isolated from the outside through the lower soundproof sealing plate, thereby completing the noise blocking inside the substation, and can release the high-pressure gas inside the substation while improving the noise prevention.

[0005] The utility model provides a sound insulation door device for a substation:

[0006] The invention comprises a door frame, a soundproof door body is hingedly connected inside the door frame, a pressure relief air chamber is opened inside the soundproof door body, a sound insulation layer is fixed inside the position where the pressure relief air chamber is connected to the back of the soundproof door body, a flame retardant filter layer is connected to the surface of the sound insulation layer, the upper part of the side of the flame retardant filter layer away from the sound insulation layer is communicated with the outside of the soundproof door body, a sound insulation sealing plate is slidably fitted under the side where the pressure relief air chamber is connected to the front of the soundproof door body, a symmetrical reset push rod is fixed on the top of the sound insulation sealing plate, and the middle part of the position where the surface of the pressure relief air chamber is fitted to the soundproof door body is communicated with the outside of the soundproof door body.

[0007] Preferably, the upper front portion of the soundproof door body is provided with equidistantly distributed air leakage holes, the air leakage holes are connected to the upper space of the soundproof sealing plate, and the surface of the reset push rod is connected to the air leakage holes.

[0008] The vent hole on the upper front side of the soundproof door body can vent the air in the reset push rod position when the high-pressure gas flows inside the pressure relief air chamber, ensuring that the soundproof sealing plate can stably receive the thrust and move upward to complete the pressure relief.

[0009] Preferably, a pressure relief outlet is provided at the lower part of the pressure relief air bin connected to the front side of the sound insulation door body, the sound insulation sealing plate is attached to the inner surface of the pressure relief outlet, and a pressure relief inlet is provided at the upper part of the pressure relief air bin connected to the back side of the sound insulation door body. The arrangement of the pressure relief outlet and the pressure relief inlet on the front and back sides of the sound insulation door body can complete the release of high-pressure gas inside the substation. At the same time, the flow airway inside the pressure relief air bin can block the leaked gas impurities, and the high-pressure gas can be used to drive the sound insulation sealing plate.

[0010] Preferably, a reset spring is provided on the inner side of the reset push rod, and the upper and lower ends of the reset spring are respectively fixed on the upper and lower surfaces inside the reset push rod. The reset spring inside the reset push rod can automatically close the door body air release channel after the high-pressure gas inside the substation is depressurized, thereby preventing the internal dangerous condition from spreading to the outside.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0023] Please see attached Figure 1-Figure 4 The utility model provides a sound insulation door device for a substation, and the sound insulation door device for a substation includes:

[0024] The door frame 1 has a soundproof door body 2 hinged on its inner side. A hinge piece 84 is fixed at the position where the soundproof door body 2 is connected to the door frame 1. A hinge seat 85 matching the hinge is fixed at the position where the door frame 1 is connected to the soundproof door body 2. A hinge rod 83 is penetrated inside the hinge seat 85 and the hinge piece 84 for hinge-connecting the door frame 1 and the soundproof door body 2. The hinge-connecting of the door frame 1 and the soundproof door body 2 by the hinge rod 83 can facilitate the disassembly and use of the soundproof door body 2. It only needs to pull out the hinge rod 83. At the same time, the hinge rod 83 is located on the inner side of the soundproof door body 2, which can ensure the safety of the door body.

[0025] A disassembly-assisting structure is provided on one side of the position where the door frame 1 is connected to the hinge seat 85, and the disassembly-assisting structure includes a winding capstan 81, the bottom end of which is fixed to the outer surface of the door frame 1, and the capstan body is rotatably connected to the inner side of the door frame 1, and a winding transmission wire 82 is connected to the inside of the winding capstan 81, and the other end of the transmission wire 82 is connected to the top of the hinge rod 83. By rotating the winding capstan 81, the hinge rod 83 can be pulled to complete the disassembly of the hinge rod 83, thereby avoiding the situation where the hinge rod 83 is too tightly connected to the inside of the hinge seat 85 and is difficult to disassemble.

[0026] It should be noted that: a direction-adjusting seat is provided directly above the hinge rod 83, and the transmission wire 82 is passed through the inner side of the direction-adjusting seat, so that the transmission wire 82 can have a vertical upward pulling force when it is retracted, thereby ensuring the pulling of the hinge rod 83.

[0027] A pressure relief gas chamber 3 is provided inside the sound insulation door body 2 for releasing the high-pressure gas inside the substation. At the same time, a vertical partition is connected to the middle of the inner side of the pressure relief gas chamber 3, so that the pressure relief of the pressure relief gas chamber 3 forms a channel-type flow pressure relief. A pressure relief air outlet 31 is provided at one end of the pressure relief gas chamber 3 connected to the front of the sound insulation door body 2. The pressure relief air outlet 31 is provided below the sound insulation door body 2, and a pressure relief air inlet 32 ​​is provided at the position where the pressure relief gas chamber 3 is connected to the back of the sound insulation door body 2. The pressure relief air inlet 32 ​​is provided at the upper part of the sound insulation door body 2. A sound insulation layer 4 is provided on one side of the pressure relief gas chamber 3 connected to the back of the sound insulation door body 2 for blocking the noise inside the substation. A flame retardant filter layer 5 is connected to the side of the sound insulation layer 4. The flame retardant filter layer 5 can block the internal flame and filter the high-pressure gas that needs to be released when an accident occurs in the substation.

[0028] A sound insulation sealing plate 6 that fits and slides in a sealing manner is provided at the bottom of the pressure relief air chamber 3 near the front of the sound insulation door body 2. The sound insulation sealing plate 6 fits the inner side of the pressure relief air outlet 31 to block the pressure relief air outlet 31 and isolate the noise inside the pressure relief air chamber 3. A symmetrical reset push rod 7 is connected to the top of the sound insulation sealing plate 6. The reset push rod 7 can use the internal reset spring 71 to push the sound insulation sealing plate 6 downward and reset it after use.

[0029] When the internal pressure of the pressure relief gas chamber 3 is sufficient, the high-pressure gas will push the sound insulation sealing plate 6 upward to complete the pressure relief of the gas.

[0030] It should be noted that blades are connected to the inner sides of the pressure relief air outlet 31 and the pressure relief air inlet 32 ​​to block the pressure relief air outlet 31 and the pressure relief air inlet 32 ​​to prevent impurities from entering.

[0031] Usage process:

[0032] When the soundproof door body 2 is removed, the soundproof door body 2 is opened, and the winding winch 81 inside the door frame 1 is rotated to pull the transmission wire 82 to complete the pulling out of the hinge rod 83. At this time, the soundproof door body 2 can be separated from the door frame 1.

[0033] When the sound insulation door body 2 is in normal use, the sound insulation sealing plate 6 will block the pressure relief outlet 31, thereby improving the noise blocking performance of the sound insulation door body 2. When an emergency occurs inside the substation, the high pressure inside the substation will pass through the pressure relief air chamber 3 and the flame retardant filter layer 5 to push the sound insulation sealing plate 6 upward, open the pressure relief outlet 31, and complete the pressure release. When the pressure relief is completed, the sound insulation sealing plate 6 will automatically close to ensure the safety of the outside of the substation.

[0034] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0035] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
