Description

Technical Field

[0001] This disclosure relates to the field of transformer substation base technology, and in particular to an emergency oil storage base for new energy transformer substations. Background Technology

[0002] In recent years, my country's new energy power generation industry has developed rapidly. While pursuing economic benefits, social benefits have also been given equal importance. Some solar and wind power generation projects select sites based on operational safety and energy distribution considerations, often in sparsely populated, undeveloped areas. However, oil-immersed transformer accidents, such as transformer oil leaks and fires, cause significant environmental damage.

[0003] In existing technologies, emergency oil storage bases for new energy transformer substations generally include: a tray body with a concave support structure, made of carbon steel or stainless steel (such as 304 / 316L), with anti-corrosion treatment on the surface as the basic load-bearing platform; a guide slope with a certain inclination angle (usually 1%-3%); an oil collection pit / tank located at the lowest point of the tray, with a cover or filter screen, and connected to an oil drain pipe at the bottom; a sealing dike with raised baffles (height ≥15cm) around its perimeter, welded and sealed without gaps; a discharge pipeline connecting the oil collection pit to an external oil storage tank / emergency pool, equipped with valves (manual / automatic); a sensor interface, which can be equipped with a liquid level sensor and a temperature sensor to connect to a monitoring system for real-time monitoring of oil leakage; and a reinforcing frame.

[0004] However, when the above-mentioned devices are in use, the transformer box is usually placed outdoors. As the usage time increases, dust will float on the filter screen on the tray body. The dust flows with the oil, increasing the viscosity of the oil and causing more solid condensation in the pipeline, which affects the subsequent flow of oil. Even if the dust is filtered, the dense dust will clog the filter screen, affecting the subsequent oil filtration operation. Utility Model Content

[0005] To solve the above-mentioned technical problems, this disclosure provides an emergency oil storage base for new energy transformer substations, including a base tray, an oil collection trough on the top of the base tray, a discharge port on the bottom inner wall of the oil collection trough, a dust removal mechanism on the side of the base tray, and a filter mechanism inside the oil collection trough.

[0006] The ash removal mechanism includes a filter fan, which is fixed to the side of the base tray. An airflow port surrounding the oil collection tank is provided in the base tray. The airflow port has a U-shaped structure. The air outlet of the filter fan is connected to the airflow port. Several ash extraction ports extending into the oil collection tank are provided on the inner wall of the airflow port.

[0007] In some embodiments, a flexible filter screen is fixedly connected to the top of the base tray, the flexible filter screen is distributed around the oil collection tank, and the flexible filter screen surrounds the outer shell of the new energy transformer.

[0008] In some embodiments, the top of the inner wall of the flexible filter is fixedly connected with a Velcro strap, which is bonded to the adhesive tape of the outer shell of the new energy transformer substation.

[0009] In some embodiments, a discharge pipe is fixedly connected to the bottom of the base tray, the discharge pipe is connected to the discharge port, and the discharge pipe has a serpentine structure.

[0010] In some embodiments, the filtration mechanism includes a filter screen, and a connecting groove is provided on the side of the base tray, the inner wall of the connecting groove forming a translational sliding fit with the filter screen.

[0011] In some embodiments, the side of the base tray has an opening extending into the connecting groove, and one side of the base tray is hinged with an opening door that covers the opening.

[0012] In some embodiments, a first magnetic block is fixedly connected to one side of the opening and closing door, and a second magnetic block is fixedly connected to one side of the base tray. The second magnetic block is embedded in the base tray, and the first magnetic block and the second magnetic block are magnetically connected.

[0013] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0014] 1. By discharging air through the outlet of the filter fan, the airflow passes through the air inlet. When the clean airflow flows through the air inlet, the air pressure is high and the air velocity is fast. This allows the air in the oil collection tank to be drawn into the air inlet through the dust extraction port and eventually discharged. This reduces the amount of dust mixed into the oil. After part of the air in the oil collection tank is extracted, the dust can be effectively removed, thus ensuring that the discharge pipe is unobstructed.

[0015] 2. By pulling open the door, the first magnetic block and the second magnetic block separate. After the door is opened, the operator can hold the handle and pull the filter screen through the inner wall of the connecting groove to replace the filter screen. When installing the filter screen, insert it into the connecting groove. Attached Figure Description

Detailed Implementation

[0023] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0024] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0025] Reference Figure 1-4 As shown in some embodiments of this application, an emergency oil storage base for a new energy transformer substation is provided, including a base tray 1, an oil collection trough 2 is provided on the top of the base tray 1, a discharge port 3 is provided on the bottom inner wall of the oil collection trough 2, an ash removal mechanism is provided on the side of the base tray 1, and a filter mechanism is provided in the oil collection trough 2.

[0026] The ash removal mechanism includes a filter fan 4, which is fixed to the side of the base tray 1. An airflow port 5 is provided in the base tray 1, which surrounds the oil collection tank 2. The airflow port 5 has a U-shaped structure. The air outlet of the filter fan 4 is connected to the airflow port 5. Several ash extraction ports 6 extending into the oil collection tank 2 are provided on the inner wall of the airflow port 5.

[0027] By setting the outlet of the filter fan 4, the airflow can pass through the airflow port 5. When the clean airflow flows in the airflow port 5, the air pressure is high and the airflow speed is fast. This allows the air in the oil collection tank 2 to be drawn into the airflow port 5 through the dust extraction port 6 and finally discharged. This reduces the amount of dust mixed into the oil. After part of the air in the oil collection tank 2 is extracted, the dust can be effectively removed, thus ensuring that the discharge pipe 15 is unobstructed.

[0028] In some embodiments, a flexible filter screen 7 is fixedly connected to the top of the base tray 1. The flexible filter screen 7 is distributed around the oil collection tank 2 and surrounds the outer shell of the new energy transformer. A Velcro 8 is fixedly connected to the top of the inner wall of the flexible filter screen 7 and is bonded to the Velcro of the outer shell of the new energy transformer.

[0029] The flexible filter 7 filters the air, preventing dust from circulating. It can be installed with Velcro 8 and its flexibility makes it easy to fit transformers of different sizes.

[0030] In some embodiments, a discharge pipe 15 is fixedly connected to the bottom of the base tray 1, the discharge pipe 15 is connected to the discharge port 3, and the discharge pipe 15 has a serpentine structure.

[0031] The serpentine discharge pipe 15 increases the number of bends in the pipeline, allowing dust to remain at the bends and reducing the amount of dust entering the final oil storage tank.

[0032] In some embodiments, the filtering mechanism includes a filter screen 9, and a connecting groove 10 is provided on the side of the base tray 1. The inner wall of the connecting groove 10 forms a translational sliding fit with the filter screen 9.

[0033] The filter screen 9 can be replaced by pulling it out through the inner wall of the connecting groove 10. When installing it, simply insert the filter screen 9 into the connecting groove 10.

[0034] In some embodiments, the side of the base tray 1 is provided with an opening 11 extending into the connecting groove 10, and an opening door 12 is hinged to one side of the base tray 1. The opening door 12 covers the opening 11. A first magnetic block 13 is fixedly connected to one side of the opening door 12, and a second magnetic block 14 is fixedly connected to one side of the base tray 1. The second magnetic block 14 is embedded in the base tray 1, and the first magnetic block 13 and the second magnetic block 14 are magnetically connected.

[0035] By opening the door 12, the first magnetic block 13 and the second magnetic block 14 are separated. After the door 12 is opened, the operator can hold the handle and pull the filter screen 9 out through the inner wall of the connecting groove 10.

[0036] Working principle: When in use, start the filter fan 4. The air outlet of the filter fan 4 will allow the airflow to pass through the air outlet 5. When the clean airflow flows in the air outlet 5, the air pressure is high and the air velocity is fast. This allows the air in the oil collection tank 2 to be drawn into the air outlet 5 through the dust extraction port 6 and finally discharged. This reduces the amount of dust mixed into the oil. After part of the air in the oil collection tank 2 is drawn away, the flexible filter screen 7 can filter the air, which can prevent the dust from circulating. Therefore, the dust can be effectively removed, ensuring that the discharge pipe 15 is unobstructed.

[0037] After a period of use, the operator can open the opening and closing door 12. At this time, the first magnetic block 13 and the second magnetic block 14 separate. After the opening and closing door 12 is opened, the operator can hold the handle and pull out the filter screen 9 through the inner wall of the connecting groove 10 to replace the filter screen 9. When installing it, simply insert the filter screen 9 into the connecting groove 10.

[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
