Description

Technical Field

[0001] The utility model belongs to the field of transformer substation cooling equipment, and in particular relates to an improved ventilation and cooling device for a power transformer substation. Background Art

[0002] A substation is a facility that transforms the high-voltage electric energy transmitted from the transmission line through a transformer, converting it into low-voltage electric energy suitable for power users. A substation is usually composed of transformers, switchgear, protection equipment, control equipment, etc., and is used to transmit electricity from the transmission line to the user's electrical equipment.

[0003] The substation will generate a high temperature during operation. In order to prevent the substation equipment from being damaged due to overheating, it is necessary to use ventilation and cooling devices to cool it down.

[0004] However, when performing maintenance work on the fan of a traditional ventilation and cooling device, the device needs to be disassembled as a whole to expose the fan for maintenance, which is cumbersome and inconvenient for personnel to use. Utility Model Content

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An improved ventilation and cooling device for a power substation comprises a main body, a shell, a fan arranged in the shell, and a protective net arranged at the front end of the shell; a maintenance mechanism, comprising a rotating component arranged between the shell and the protective net, and a limiting component arranged on the periphery of the shell; and a limiting mechanism, arranged between the protective nets.

[0008] Preferably, a fixing frame is provided between the fan and the housing, and a mounting plate is provided at the rear end of the housing.

[0009] Preferably, the rotating assembly includes fixed rods arranged on both sides of the protective net, and a rotating seat arranged between the fixed rods and the shell.

[0010] Preferably, the limiting assembly includes a movable shell arranged at the periphery of the shell, and an electric push rod arranged between the movable shell and the shell.

[0011] Preferably, the limiting mechanism includes a guide rail arranged on the protective net, a slider arranged in the guide rail, a boosting block arranged on the slider, and a rubber pad arranged on the inner side of the guide rail.

[0012] Preferably, two groups of the limiting mechanisms are provided, and the two groups of the limiting mechanisms are respectively located at the top and the bottom of the protective net, and the guide rail is slidably connected to the slider.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The utility model can drive the movable shell to move through the maintenance mechanism when the fan needs to be maintained, release the position limit of the protective net, and then rotate the protective net open through the rotating seat to expose the fan, making it convenient for personnel to perform maintenance work on the fan.

[0015] (2) The utility model can use the limiting mechanism to slightly push the slider after the fan maintenance is completed and the protective net is rotated closed, so that the slider is on two protective nets at the same time, so as to limit the position of the protective net and ensure the stability during subsequent work. The rubber pad can automatically limit the position of the slider after the adjustment is completed. The operation is simple and quick, and it is convenient for personnel to use.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] As attached Figure 1 To Attachment Figure 4 As shown:

[0023] Embodiment 1: The utility model provides an improved ventilation and cooling device for a power substation, comprising a main body 1, including a shell 101, a fan 104 arranged in the shell 101, and a protective net 105 arranged at the front end of the shell 101; a maintenance mechanism 2, comprising a rotating component arranged between the shell 101 and the protective net 105, and a limiting component arranged on the periphery of the shell 101; and a limiting mechanism 3, arranged between the protective nets 105.

[0024] Specifically, a fixing frame 103 is disposed between the fan 104 and the housing 101 , and a mounting plate 102 is disposed at the rear end of the housing 101 .

[0025] Furthermore, the rotating assembly includes fixed rods 203 disposed on both sides of the protection net 105 , and a rotating seat 204 disposed between the fixed rods 203 and the housing 101 .

[0026] Furthermore, the limiting assembly includes a movable shell 201 disposed on the periphery of the shell 101 , and an electric push rod 202 disposed between the movable shell 201 and the shell 101 .

[0027] As can be seen from the above, when in use, the device is installed at the vent of the substation through the mounting plate 102, and the fan 104 is started. The fan 104 will increase the air flow speed in the substation, thereby ventilating and cooling the substation equipment. The protective net 105 will protect the fan 104 to prevent it from being directly exposed to the outside and causing safety hazards. When maintenance work on the fan 104 is required, the electric push rod 202 can be started. The electric push rod 202 will drive the movable shell 201 to move back and forth on the shell 101, so that the movable shell 201 is separated from the protective net 105, so as to release the rotation restriction of the protective net 105 until the movable shell 201 and the protective net 105 are separated. The shell 101 is overlapped to expose the fan 104, and then the protective net 105 is pushed to rotate it toward both sides of the device with the rotating seat 204 as the axis to open the device. At this time, the fan 104 will be directly exposed in front of the staff, making it convenient for the staff to perform maintenance work on the fan 104. After the maintenance is completed, the protective net 105 is rotated in the initial direction until the two protective nets 105 are in contact and engaged, and then the electric push rod 202 is started to push the movable shell 201 to move in the initial direction until the movable shell 201 is in contact with the protective net 105, thereby limiting the position of the protective net 105 so that it cannot rotate, thereby ensuring stability during work.

[0028] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the limiting mechanism 3 includes a guide rail 301 arranged on the protective net 105, a slider 302 arranged in the guide rail 301, a booster block 303 arranged on the slider 302, and a rubber pad 304 arranged on the inner side of the guide rail 301.

[0029] Specifically, two groups of limiting mechanisms 3 are provided. The two groups of limiting mechanisms 3 are respectively located at the top and the bottom of the protection net 105 , and the guide rail 301 is slidably connected to the slider 302 .

[0030] As can be seen from the above, when it is necessary to perform maintenance work on the fan 104, the slider 302 can be pushed by the assisting block 303 to drive the slider 302 to move in the guide rail 301 until the slider 302 completely slides into the guide rail 301 and separates from the other protective net 105 to release the connection between the two protective nets 105. At this time, the protective net 105 can be rotated open by the rotating seat 204, which is convenient for personnel to perform maintenance work on the fan 104. When the maintenance is completed and the protective net 105 is rotated and closed to return to the initial position, the slider 302 can be pushed in the initial direction so that it is on the two protective nets 105 at the same time, so that the positions of the two protective nets 105 are limited by the close fit between its own bottom arc surface and the outer arc surface of the protective net 105, further ensuring the stability of the protective net 105 during work, and facilitating the use of personnel. After the adjustment of the slider 302 is completed, the rubber pad 304 will squeeze and limit the position of the slider 302 through its own elasticity, so that the slider 302 will be automatically limited after the adjustment is completed, without manual limitation, thereby improving work efficiency.
