Detailed Description
The embodiment of the invention discloses an assembled accident oil pool which does not need to occupy a large amount of manpower, material resources and time, so that the commissioning speed and efficiency of a mobile substation are improved.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention discloses an assembled accident oil pool which comprises an oil receiving pool, wherein the oil receiving pool is arranged around the circumference of a trailer bottom plate 4. The oil receiving tank is used for receiving oil discharged from the transformer 5. The oil receiving tank specifically comprises an oil tank bottom plate 1 and a side baffle 2. The side baffle 2 is arranged on one side of the oil pool bottom plate 1 and is used for blocking accident oil discharged onto the oil pool bottom plate 1. One side of the oil pool bottom plate 1 far away from the side baffle plate 2 is locked on the trailer bottom plate 4 through bolts.
In the invention, the oil pool bottom plate 1 and the side baffle plate 2 can be prefabricated in the factory in advance and assembled after arriving at the site. Because oil sump bottom plate 1 passes through the bolt to be connected with trailer bottom plate 4, consequently only need with oil sump bottom plate 1 locking on trailer bottom plate 4 can, the equipment is convenient, swift, need not occupy a large amount of manpower, material resources and time to the speed of commissioning and the efficiency of mobile substation have been improved.
Specifically, the side of the oil pool bottom plate 1 far away from the side baffle 2 is provided with an ear plate 6. The surface of the ear plate 6 is jointed with the side end surface of the trailer bottom plate 4. The ear plate 6 is provided with a first bolt hole, and the side end face of the vehicle bottom plate is provided with a second bolt hole matched with the first bolt hole. When the oil pool bottom plate 1 is installed, the lug plate 6 is attached to the side end face of the trailer bottom plate 4, the first bolt hole and the second bolt hole are aligned, and then the bolts are screwed.
The lug plate 6 extends along the up-down direction, the number of the first bolt holes is two, and the two first bolt holes are arranged up and down. Correspondingly, two second bolt holes are arranged on the side end face of the trailer bottom plate 4. One bolt is screwed in each first bolt hole. So, the fastness of being connected of oil sump bottom plate 1 and trailer bottom plate 4 has been ensured.
The oil receiving pool is formed by assembling a plurality of L-shaped plates. The horizontal plates of the L-shaped plates form the sump floor 1. The vertical plates of the L-shaped panels constitute side dams 2. Two adjacent L-shaped plates are connected through bolts. During the manufacturing process in the factory, the L-shaped plates are produced in batches, and after the L-shaped plates arrive at the site, the L-shaped plates with corresponding quantity are assembled into the oil receiving pool around the trailer bottom plate 4 according to the actual size of the trailer bottom plate 4.
The assembled accident oil pool of the present invention comprises an oil collecting tank 3 in addition to the oil collecting tank. The oil collecting tank 3 is arranged right below the oil receiving pool and is arranged along the circumferential direction. The accident oil in the oil receiving pool can flow into the oil collecting tank 3 through the oil pool bottom plate 1. In this way, the accident oil discharged from the transformer 5 first falls into the oil receiving tank, and then flows into the oil collecting tank 3 below and is collected.
In the present invention, the oil receiving sump is closely arranged around the trailer floor 4, and the oil collecting sump 3 is arranged on the ground and is located right below the oil receiving sump. Because the oil receiving pool is tightly arranged around the trailer bottom plate 4, the oil collecting tank 3 right opposite to the oil receiving pool has a smaller outward expansion range relative to the trailer bottom plate 4, so that the occupied area is reduced, and the installation of the assembly type accident oil pool is facilitated.
The oil collecting grooves 3 are formed by splicing groove plates, and the adjacent oil collecting grooves 3 are connected through bolts.
In order to ensure that the accident oil in the oil receiving pool can fall into the oil collecting tank 3 below, the invention limits the downward projection of the oil receiving pool to fall into the area of the oil collecting tank 3.
In one embodiment of the present invention, the horizontal plate of the L-shaped plate has a width of 1m, a length of 1m, and a thickness of 5 cm. The height of the vertical plate of the L-shaped plate is 1 m. And the L-shaped plate is a stainless steel plate. The width of the slot plate is 1.1m, the height is 1m, the length is 1m, and the thickness is 5 cm.
Next, the specific structure of the oil sump floor 1 of the oil sump will be described: the oil pool bottom plate 1 specifically comprises an upper layer bottom plate and a lower layer bottom plate. An upper layer oil unloading hole is formed in the upper layer bottom plate, and a lower layer oil unloading hole is formed in the lower layer bottom plate. A plurality of fireproof blocks are arranged in an interlayer formed by the upper layer bottom plate and the lower layer bottom plate. Gaps for accident oil to pass through are formed among the fire-proof blocks.
The accident oil that unloads from transformer 5 at first falls into and connects the oil bath, and the accident oil enters into the intermediate layer that upper floor bottom plate and lower floor bottom plate formed through upper oil discharge hole, because the fire prevention bulk has the fire prevention effect, even consequently accident oil has burnt, accident oil when through the fire prevention bulk, the fire can extinguish. Then the accident oil falls into the oil collecting tank 3 through the lower layer oil discharging hole. So, can prevent that oil charge electrical equipment such as transformer 5 from damaging the back, accident oil leaks and arouses that the conflagration etc. makes the accident enlarge, and simultaneously more environmental protection is convenient.
The fireproof blocks are cobblestones, and gaps for accident oil to pass through are formed between adjacent cobblestones. The cobblestones have strong cooling and isolating functions, so that the accident can be prevented from being expanded. The fire-resistant block is not particularly limited, and is within the scope of the present disclosure, as long as the fire-resistant block can extinguish the accident oil fire and allow the accident oil to pass through.
The upper floor is in particular an upper grid plate 11 and the lower floor is in particular a lower grid plate 12. The grid plates are readily available and the grid structure is capable of allowing the passage of incident oil.
In conclusion, the assembled accident oil pool provided by the invention has the following beneficial effects:
firstly, the method comprises the following steps: the oil receiving pool is formed by assembling L-shaped stainless steel plates, the oil collecting tank 3 is formed by assembling stainless steel trough plates, the L-shaped stainless steel plates and the stainless steel trough plates are processed in advance and then assembled on site, and therefore the commissioning speed and efficiency of the mobile substation can be improved.
Secondly, the method comprises the following steps: between the L type corrosion resistant plate to and through bolted connection between L type corrosion resistant plate and the trailer bottom plate 4, the equipment is convenient, and sound construction.
Thirdly, the method comprises the following steps: an oil receiving pool is arranged around the trailer bottom plate 4, an oil collecting tank 3 is arranged below the oil receiving pool, cobblestones are arranged in the oil receiving pool bottom plate 1 of the oil receiving pool, the oil receiving pool is used for receiving accident oil unloaded from the transformer 5, the accident oil falls into the oil collecting tank 3 after passing through the cobblestones, and the whole assembly type accident oil receiving pool is clear, concise and compact in structure and convenient to install and maintain.
