Description

Technical Field

[0001] This application belongs to the field of construction, specifically to a power compartment and water communication compartment for a shared drainage pump. Background Technology

[0002] like Figure 1 As shown, the power compartment is generally located next to the water communication compartment. Traditionally, both the water communication compartment and the power compartment have their own independent drainage pumps, preventing them from being connected and creating a fireproof barrier. The pressure drain pipe of the pump in the power compartment extends outwards along the outside of the high-voltage cable. When the high-voltage cable is installed, the existing pressure drain pipe in the power compartment needs to be removed, and then reinstalled after the high-voltage cable is laid. This is because the power compartment needs drainage before and after the high-voltage cable is installed, but the pressure drain pipe needs to be removed during the installation of the high-voltage cable to facilitate its installation within the power compartment. This structure has two drawbacks:

[0003] 1. The secondary reinstallation of the pressure drain pipe caused repeated construction work and unnecessary losses in the amount of work completed.

[0004] 2. The power compartment is equipped with a separate drainage pump, and the number of drainage pumps is relatively large, which increases the operation and maintenance work. Utility Model Content

[0005] The purpose of this application is to address the shortcomings of existing technologies by using a connecting pipe to link the power compartment and the water communication compartment together. This design allows for a power compartment and water communication compartment that require only one drainage system, thus solving the problems of ensuring fireproof isolation between the power compartment and the water communication compartment while avoiding repeated construction and multiple drainage pumps.

[0006] To achieve the above objectives, the technical solution adopted in this application is:

[0007] A power compartment and a water communication compartment for a shared drainage pump include a power compartment and a water communication compartment. The power compartment is located on one side of the water communication compartment and is isolated from it. The bottom of the power compartment and the bottom of the water communication compartment are respectively provided with a first water collection pit and a second water collection pit. The first water collection pit and the second water collection pit are connected by a connecting pipe. A drainage pump is provided in the second water collection pit. One end of a pressure drainage pipe is connected to the outlet end of the drainage pump, and the other end extends out of the water communication compartment after passing through the water communication compartment. The height of the connecting pipe at the end in the first water collection pit is lower than the height of the connecting pipe at the end in the second water collection pit. There is a predetermined gap between the inner bottom wall of the first water collection pit and the end of the connecting pipe at the first water collection pit.

[0008] Preferably, a level gauge is provided in the second water sump, and the level gauge is signal-connected to the drainage pump.

[0009] Preferably, an alarm is installed in the second water accumulation pit, and the alarm signal is connected to the level gauge.

[0010] Preferably, the connecting pipe is inverted L-shaped, with the top of the vertical part of the connecting pipe connected to one end of the horizontal part. The vertical part of the connecting pipe is located in the first water-collecting pit, and the free end of the horizontal part of the connecting pipe extends from the first water-collecting pit into the second water-collecting pit. There is a preset distance between the free end of the vertical part of the connecting pipe and the inner bottom wall of the first water-collecting pit.

[0011] Preferably, the volume of the first water collection pit is smaller than the volume of the power compartment, and the volume of the second water collection pit is smaller than the volume of the water communication compartment.

[0012] Preferably, the volume of the first water-collecting pit is smaller than the volume of the second water-collecting pit.

[0013] Preferably, the opening of the first water sump faces upward, and a drainage ditch is provided on the inner bottom wall of the power compartment, with one end of the drainage ditch extending to the opening of the first water sump.

[0014] Compared with the prior art, this application has the following beneficial effects:

[0015] 1. This application adopts a method of connecting the power compartment and the water communication compartment together by connecting pipes, and designs a power compartment and water communication compartment that only require one drainage system, thereby solving the problem of how to ensure fireproof isolation between the power compartment and the water communication compartment while avoiding repeated construction and multiple drainage pumps.

[0016] 2. In this application, the lowest effective water level in the first water collection pit (the water collection pit inside the power compartment) is H+0.400, while the water level in the adjacent water and communications compartment where the drainage pump is stopped is H+0.300, and the lowest alarm water level is H+0.200. The bottom of the connecting pipe is 300mm below the lowest water level in the first water collection pit, i.e., at an elevation of H+0.100. When the water level in the first water collection pit is higher than H+0.400, water automatically flows into the adjacent second water collection pit through the connecting pipe and is discharged by the drainage pump; when the water level in the first water collection pit is lower than H+0.400, the water stops flowing and remains in the first water collection pit, thus forming an effective fireproof partition between the interior of the power compartment and the interior of the water and communications compartment, meeting the fireproof partition requirements between different fire compartments. Attached Figure Description

[0017] Figure 1 This is a schematic diagram of the structure of the power compartment and the water communication compartment in traditional technology;

[0018] Figure 2 This is a structural diagram of the power compartment and the water communication compartment in this application.

[0019] The components include: 1. Power compartment; 2. Water and communication compartment; 3. First water collection pit; 4. Second water collection pit; 5. Connecting pipe; 6. Drainage pump; 7. Level gauge; 8. Drainage ditch; and 9. Pressure drain pipe. Detailed Implementation

[0020] like Figure 2 As shown, a power compartment and a water communication compartment for a shared drainage pump include a power compartment 1 and a water communication compartment 2. The power compartment 1 is located on one side of the water communication compartment 2 and is isolated from it. The bottom of the power compartment 1 and the bottom of the water communication compartment 2 are respectively provided with a first water collection pit 3 and a second water collection pit 4. The first water collection pit 3 and the second water collection pit 4 are connected by a connecting pipe 5. A drainage pump 6 is provided in the second water collection pit 4. One end of a pressure drainage pipe 9 is connected to the outlet end of the drainage pump 6, and the other end extends out of the water communication compartment 2 after passing through the water communication compartment 2. The height of the end of the connecting pipe 5 in the first water collection pit 3 is lower than the height of the end of the connecting pipe 5 in the second water collection pit 4. There is a preset gap between the inner bottom wall of the first water collection pit 3 and the end of the connecting pipe 5 in the first water collection pit 3.

[0021] In this embodiment, water from the power compartment 1 enters the first water sump 3 and then flows through the connecting pipe 5 into the water communication compartment 2. It is then drained by the drainage pump 6 within the water communication compartment 2. Since both the water communication compartment 2 and the power compartment 1 share the same drainage pump 6 within the water communication compartment 2, the first water sump 3 does not require a separate drainage pump 6, thus reducing the number of pumps needed. Furthermore, the power compartment 1 does not require the installation of a pressure drain pipe 9, eliminating the need to disassemble the pressure drain pipe 9 during high-voltage cable installation, reducing workload and avoiding redundant construction. Because the height of the connecting pipe 5 at one end in the first water sump 3 is lower than the height of its end in the second water sump 4, when not draining, the water in the first water sump 3 seals off the connecting pipe 5 at one end, effectively creating an airtight barrier between the water communication compartment 2 and the power compartment 1, thus providing a fireproof barrier.

[0022] As a preferred embodiment, a level gauge 7 is installed in the second sump 4, and the level gauge 7 is signal-connected to the drainage pump 6. After installing the level gauge 7, as... Figure 2 As shown, the water level at which the drainage pump 6 starts and the water level at which it stops can be designed as needed. This is because a certain amount of water needs to be retained in the second sump 4.

[0023] As a preferred embodiment, the second sump 4 is equipped with an alarm, the alarm signal of which is connected to the level gauge 7. By installing the alarm, when the level gauge 7 malfunctions and the drain pump 6 fails to start, the alarm will alert the worker to manually start the drain pump 6; conversely, when the drain pump 6 should be shut down but is not, the alarm will alert the worker to manually shut it down. Figure 2 As described: the lowest effective water level in the first water collection pit 3 (the water collection pit inside the power compartment 1) is H+0.400, while the water level in the adjacent water and communication compartment 2 where the drainage pump 6 is stopped is H+0.300, and the lowest alarm water level is H+0.200. The bottom of the connecting pipe 5 is 300mm below the lowest water level in the first water collection pit 3, i.e., at an elevation of H+0.100. When the water level in the first water collection pit 3 is higher than H+0.400, water automatically flows into the adjacent second water collection pit 4 through the connecting pipe 5 and is discharged by the drainage pump 6; when the water level in the first water collection pit 3 is lower than H+0.400, the water stops flowing and remains in the first water collection pit 3, thus forming an effective fireproof partition between the interior of the power compartment 1 and the interior of the water and communication compartment 2, meeting the fireproof partition requirements between different fire compartments.

[0024] As a preferred embodiment, the connecting pipe 5 is inverted L-shaped, with the top of the vertical portion of the connecting pipe 5 connected to one end of the horizontal portion. The vertical portion of the connecting pipe 5 is located within the first water-collecting pit 3, and the free end of the horizontal portion of the connecting pipe 5 extends from the first water-collecting pit 3 into the second water-collecting pit 4. A predetermined distance is maintained between the free end of the vertical portion of the connecting pipe 5 and the inner bottom wall of the first water-collecting pit 3. This arrangement ensures that the height of the end of the connecting pipe 5 within the first water-collecting pit 3 is lower than the height of the end of the connecting pipe 5 within the second water-collecting pit 4, thus providing a fireproof barrier between the power compartment 1 and the water-communication compartment 2. Alternatively, the connecting pipe 5 can be designed as a straight line installed at an angle, so that the height of the end of the connecting pipe 5 within the first water-collecting pit 3 is lower than the height of the end of the connecting pipe 5 within the second water-collecting pit 4.

[0025] As a preferred embodiment, the volume of the first water collection pit 3 is smaller than the volume of the power compartment 1, and the volume of the second water collection pit 4 is smaller than the volume of the water communication compartment 2. This arrangement reduces the amount of construction work required.

[0026] As a preferred approach, since a drainage pump 6 is not required in the first water collection pit 3, the volume of the first water collection pit 3 is smaller than the volume of the second water collection pit 4. This reduces the amount of construction work and lowers costs.

[0027] As a preferred embodiment, the opening of the first water collection pit 3 faces upward, and a drainage ditch 8 is provided on the inner bottom wall of the power compartment 1. One end of the drainage ditch 8 extends to the opening of the first water collection pit 3 and communicates with it. By providing the drainage ditch 8, water on the inner bottom wall of the power compartment 1 is diverted into the first water collection pit 3.
