Description

Technical Field

[0001] The present invention relates to the technical field of flood prevention and drainage, in particular to a flood prevention emergency drainage device for a transformer substation. Background Art

[0002] Substations, as the core hub of regional power grids, typically utilize a drainage system consisting of pre-buried drainage pipes and fixed pump sets for their underground cable layers, equipment pits, and cable trenches. However, in the context of frequent extreme weather events, such as heavy rain, the drainage system's efficiency is insufficient to quickly drain water, necessitating the installation of emergency drainage devices.

[0003] The drainage pipes of existing emergency drainage devices are prone to blockage, and there are a large number of dead leaves and branches in the cable trench. The current measure is to install a filter at the water inlet end of the drainage pipe, but this will cause dead leaves and branches to accumulate at the filter, thereby affecting the drainage effect.

[0004] In view of the above problems, the present invention provides a substation flood prevention emergency drainage device to solve the above problems. Summary of the Invention

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a substation flood control emergency drainage device, characterized in that it includes:

[0020] Furthermore, preferably, the blades of the crushing leaf 1 and the crushing leaf 2 are arranged at an angle to divert water and dead leaves.

[0021] Further, preferably, the first filter assembly includes:

[0022] A filter cartridge is rotatably disposed in the housing and has a water inlet at one end thereof close to the water pump;

[0023] A driving motor is fixed in the housing, and an output end thereof is fixedly connected to the filter cartridge;

[0024] The first filter hole is configured as a plurality of equidistantly arranged on the filter cartridge;

[0034] Compared with the prior art, the present invention provides a substation flood control emergency drainage device with the following beneficial effects:

[0035] In the present invention, a two-stage crushing structure is adopted in conjunction with inclined blades to actively cut dead leaves and branches, and at the same time guide the direction of water flow to avoid the accumulation of debris from the source.

Moreover, after filtering for a period of time, the position of the filter cartridge is adjusted by the driving motor so that the filter holes between the next group of partitions can be filtered, avoiding accumulation and clogging caused by filtering at the same position for a long time. When the water volume is large, the centrifugal force generated by the driving motor to rotate the filter cartridge can accelerate the separation of impurities and improve the filtration efficiency. The adjustment slot of the second filter component can prevent the water flow from always falling at the same position of the filter screen, thereby improving the utilization rate of the filter screen and avoiding clogging of the filter screen due to accumulation.

[0041] Reference Figure 1-Figure 4 The present invention provides a technical solution: a substation flood control emergency drainage device, comprising:

[0042] Base 1, fixed above the cable trench;

[0043] The housing 2 is fixed to the upper end surface of the base 1;

[0044] A drainage assembly 3 is slidably arranged on the base 1;

[0045] A lifting cylinder 5 is fixed on the base 1, and its output end is fixed to the drainage assembly 3;

[0046] A water pump 6 is fixed to one side of the housing 2, and its water inlet is connected to the drainage assembly 3 via a connecting pipe 4;

[0047] A first filter assembly 7 is installed in the housing 2 and is connected to the water outlet of the water pump 6;

[0048] The second filter assembly 8 is fixed on one side of the base 1 .

[0049] It should be noted that a protective shell (not shown in the figure) is fixed to the outside of the device to prevent rainwater from entering the interior of the device.

[0050] In this embodiment, the drainage component 3 includes:

[0051] A drain pipe 31 is slidably provided on the base 1 and fixed to the output end of the lifting cylinder 5 , and the drain pipe 31 is slidably connected to the connecting pipe 4 ;

[0052] A crushing chamber 32 is fixed on the drain pipe 31;

[0053] The first bracket 33 is configured as a plurality of brackets and is circumferentially arranged on the side wall of the crushing chamber 32, and a crushing motor 1 is fixed in the middle of the first bracket 33;

[0054] Crushing blade 1 34, rotatably mounted on the bracket 1 33 and driven by the crushing motor 1;

[0055] The second bracket 35 is fixed to the bottom of the drain pipe 31, and the second crushing motor is fixed in the middle position;

[0056] The second crushing blade 36 is rotatably mounted on the second bracket 35 and is driven by the second crushing motor.

[0057] As a preferred embodiment, the blades of the crushing blade 1 34 and the crushing blade 2 36 are arranged at an angle to divert water and dead leaves.

[0058] That is to say, the dual-stage crushing structure of the crushing blade 1 34 and the crushing blade 2 36 in combination with the inclined blades can actively cut dead leaves and branches, while guiding the direction of water flow to avoid accumulation of debris from the source.

[0059] In this embodiment, the first filter assembly 7 includes:

[0060] The filter cartridge 71 is rotatably disposed in the housing 2 and has a water inlet 73 at one end thereof close to the water pump 6;

[0061] The driving motor 72 is fixed in the housing 2, and the output end is fixedly connected to the filter cartridge 71;

[0062] The first filter hole 74 is configured as a plurality of equidistantly opened on the filter cartridge 71;

[0063] The partitions 75 are configured in plurality and are circumferentially arranged in the filter cartridge 71 .

[0064] As a preferred embodiment, when the driving motor 72 operates in a reciprocating motion, the distance of each reciprocating motion is the distance between the two partitions 75 .

[0065] That is to say, when drainage operations are being performed, the driving motor 72 operates in a reciprocating motion, so that the water entering the water inlet 73 falls between the two partitions 75, and the reciprocating motion of the filter cartridge 71 can automatically disperse impurities, forming dynamic filtration. After filtering for a period of time, the position of the filter cartridge 71 is adjusted by the driving motor 72, so that the filter hole 74 between the next group of partitions 75 is filtered, avoiding accumulation and blockage caused by long-term filtering at the same position. At this time, when the water volume continues to increase, the filter cartridge 71 is rotated by the driving motor 72 to generate centrifugal force to accelerate the separation of impurities and improve the filtration efficiency.

[0066] As a preferred embodiment, the second filter assembly 8 includes:

[0067] The water outlet trough 81 is fixed to the lower end surface of the housing 2 and is located below the filter cartridge 71;

[0068] A water outlet 82 is provided on the water outlet trough 81;

[0069] The filter chamber 83 is fixed on one side of the base 1, and a filter screen is fixed on its upper end surface, and a plurality of filter holes 84 are opened on the filter screen;

[0070] The fixing plate 85 is fixed to one side of the filter chamber 83 close to the water outlet 82, and the regulating cylinder is fixed to the lower end;

[0071] The adjusting groove 86 is slidably provided on the fixing plate 85 and driven by the adjusting cylinder. Two drain ports 87 are symmetrically provided at both ends of the adjusting groove 86 .

[0072] It should be noted that the regulating cylinder can drive the regulating groove 86 to perform reciprocating motion, thereby moving the two drain outlets 87 on the filter bin 83, preventing the water flow from always falling at the same position of the filter bin 83, improving the utilization rate of the filter screen, and avoiding blockage of the filter screen due to accumulation.

[0073] As a preferred embodiment, the aperture of the first filter hole 74 is larger than the aperture of the second filter hole 84 .

[0074] That is to say, the first filter component (with a larger pore size) prioritizes intercepting large particles of debris, and the second filter component (with a smaller pore size) performs fine filtration. The graded processing reduces the single-stage load and extends the life of the filter.

[0075] Specifically, when the water level in the cable trench reaches the set safety value, the emergency drainage device is started. First, the drainage component 3 is extended into the water through the lifting cylinder 5, and then the water pump 6, crushing motor 1 and crushing motor 2 are turned on to flow the water and crush the dead leaves and branches in the water to avoid clogging the pipe. Then, the first filter component 7 and the second filter component 8 perform double filtration, and the filtered water is discharged into the sewer to avoid clogging the sewer with dead leaves and branches in the water. The crushed dead leaves and branches can then be collected and utilized to save energy.

[0076] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
