Description

Technical Field

[0001] The present invention relates to the technical field of electric power devices, and more particularly to a prefabricated box-type transformer substation. Background Art

[0002] Prefabricated box-type substation is a power conversion device that converts high-voltage direct current into low-voltage or medium-voltage alternating current. It is generally used in various industries that require electricity resources, such as residential areas and factories. The prefabricated box-type substation converts the high-voltage direct current used for transmission into medium- and low-voltage alternating current for households or mechanical equipment.

[0003] In order to reduce the loss of power resources during transmission, high-voltage direct current is generally used for transmission during the power transmission process. When the power reaches the user's area, the high-voltage direct current cannot be directly applied to home appliances or equipment, and power conversion is required through a substation. In some remote areas, far away from the substation, laying lines is costly and has high maintenance costs. The problem can be solved by using a prefabricated box substation.

[0027] What needs to be specifically explained in this embodiment is that by modifying the door panel, it can be quickly opened during maintenance and operations over a larger area can be performed. By providing an opening structure 2, it can be quickly opened. By providing a door panel fixing pin 207, the door panel can be effectively fixed.

[0028] Reference Figure 7 and Figure 8The cooling structure 3 includes a drainage pipe 301, two water injection pipes 302 are arranged on the top of the drainage pipe 301, a door panel water inlet pipe 303 is arranged at the front of the water injection pipe 302, a spherical blocking body 3031 is arranged on the other side of the door panel water inlet pipe 303, a moving rod 3032 is arranged on the other side of the spherical blocking body 3031, a moving groove 3033 is arranged on the outer surround of the other side of the moving rod 3032, an ejection limit column 3034 is fixedly connected to the other side of the moving rod 3032, a flow limiting spring 3035 is fixedly connected to the other side of the ejection limit column 3034, a pulling rope 3036 is fixedly connected to the middle part of the other side of the ejection limit column 3034, and a door panel fixing pin 207 is fixedly provided on the other end of the pulling rope 3036.

[0029] What needs to be specifically explained in this embodiment is that by providing a cooling structure 3, the problem of internal heat dissipation is further effectively solved. By collecting rainwater and rotating it inside the device casing, the device casing is kept in a cooling state, thereby improving the internal heat dissipation effect.

[0030] Reference Figure 1 The main structure 101 and the door panel structure 103 are both hollow inside, and the top and bottom of the support seat 106 to which the top and bottom of the four support columns 107 are fixedly connected are respectively fixedly connected to the bottom of the cover structure 102 and the top of the inner side of the main structure 101.

[0031] What needs to be specifically explained in this embodiment is that the main structure 101 and the door panel structure 103 are both hollow inside, which can help the water flow to circulate, so that the device casing is in a low temperature state, so that it can interact with the internal heat in time, and its internal heat dissipation effect is better.

[0032] Reference Figure 3 and Figure 6 The first pulley 204 and the second pulley 206 are respectively located at two bends of the wire rope 205. The top end of the wire rope 205 is fixedly connected to the top of the limit plate 2073, and the bottom end of the wire rope 205 is fixedly connected to the back of the top of the toggle rod 2012. The diameter of the limit plate 2073 is matched with the internal slot size of the fixed shell 2071, and the ratio of the diameter of the ejection spring 2072 to the diameter of the limit plate 2073 is three to four.

[0033] What needs to be specifically explained in this embodiment is that, by the first pulley 204 and the second pulley 206 being respectively located at two bends of the wire rope 205, the position of its force can be changed to help the equipment open, and by the top end of the wire rope 205 being fixedly connected to the top of the limit plate 2073, and the bottom end of the wire rope 205 being fixedly connected to the back of the top of the toggle rod 2012, its force can act on the door panel fixing pin 207 to hit the door panel structure 103.

[0034] Reference Figure 4 , Figure 5 and Figure 6 The contact surface between the fixing rod 2034 and the toggle rod 2012 is round head-shaped, and the push spring 2032 is in a compressed state when not working. The fixing rod 2034 is against the middle of the outer back of the toggle rod 2012 when not working.

[0035] It should be specifically explained in this embodiment that the contact surface between the fixing rod 2034 and the toggle rod 2012 is round-headed, which can help to better fix the device and also facilitate the resetting of the device.

[0036] Reference Figure 7 and Figure 8 The height of the drainage pipe 301 is located at two-thirds of the height of the bottom of the main structure 101. The tops of the two water injection pipes 302 are connected to the direction groove opened at the top of the main structure 101, and the bottoms are connected to the groove dug inside the main structure 101. The bottom of the door panel water inlet pipe 303 is connected to the door panel, and the top of the door panel water inlet pipe 303 is connected to the direction groove opened at the top of the main structure 101. The bottoms of the two door panel structures 103 are provided with hoses connected to the internal grooves of the main structure 101.

[0037] It should be specifically explained in this embodiment that the height of the drainage pipe 301 is located at two-thirds of the height of the bottom of the main structure 101, so that water can be stored at the bottom in non-rainy weather, so that the bottom of the device continues to be in a cool state, and the heat inside the device can be dissipated to protect the operation of the device.

[0038] Reference Figure 7 and Figure 8 A groove is provided at the bend of the door panel water inlet pipe 303, and its size is the same as that of the spherical plug 3031. The size of the spherical plug 3031 is the same as the size of the internal pipe of the door panel water inlet pipe 303. The other end of the pulling rope 3036 is fixedly connected to the top of the limit plate 2073 inside the door panel fixing pin 207.

[0039] What needs to be specifically explained in this embodiment is that by making the size of the spherical blocking body 3031 the same as the internal pipe size of the door panel water inlet pipe 303, it can prevent water from continuing to flow along the board when the equipment is being repaired on rainy days, causing water accumulation inside the door panel structure 103 and water outflow when the door panel structure 103 is opened. It can also prevent water from continuing to flow down from the bottom of the door panel water inlet pipe 303 when the equipment is being repaired on rainy days, causing maintenance difficulties.

[0040] The device of the present invention collects rainwater through the directional grooves opened on the top of the main structure 101, so that the rainwater flows into the grooves inside the main structure 101 and the door panel structure 103 through two water injection pipes 302 and the door panel water inlet pipe 303, thereby cooling the internal temperature, achieving a water heat dissipation effect, and protecting the internal temperature from being too high and causing damage to the equipment.

[0041] When the inside of the equipment needs to be inspected on a rainy day, the lock body 202 is opened with a key so that it no longer locks the opening box 201, the opening plate 2011 is opened, and the lever 2012 is pushed downward. The lever 2012 is pushed downward so that the connecting blocks 2015 on both sides of the lever 2012 move downward. The lever 2012 moves downward so that it no longer supports the fixing rod 2034. The fixing rod 2034 is no longer supported by force, so that the push-open spring 2032 is released. The push-open spring 2032 pushes the limit disc 2033 to move, the limit disc 2033 moves and drives the fixed rod 2034 to move, the limit disc 2033 moves and pulls the push-open spring 2032, the push-open spring 2032 moves and pulls the pendant 2036, when the toggle rod 2012 moves to the bottom limit, the fixed rod 2034 is fully extended to make it stuck to the toggle rod 2012, the toggle rod 2012 moves downward and pulls the wire rope 205, the wire rope 205 05 is stretched at one end to move the other end of the wire rope 205. The wire rope 205 is stretched to pull up the limit plate 2073. The limit plate 2073 moves to compress the ejection spring 2072. The limit plate 2073 moves to drive the ejection fixing rod 2074 to move. The ejection fixing rod 2074 moves so that it no longer fixes the door panel structure 103. The limit plate 2073 moves toward the top to relax the pulling rope 3036. The pulling rope 3036 relaxes so that the current limiting spring 3035 is no longer forced to pop out. The current limiting spring 3035 pops out and pushes the ejection limit column 3034 to move. The ejection limit column 3034 moves to push the moving groove 3033 to move. The moving groove 3033 moves to push the spherical blocking body 3031 to move. The spherical blocking body 3031 moves to block the door panel water inlet pipe 303 so that it is no longer filled with water. After waiting for 5 seconds, the water flow inside the door panel structure 103 is exhausted, and the door panel structure 103 is opened for maintenance.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
