[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] like Figure 1 As shown:

[0025] A drainage, pressure-reducing and anti-floating device for an underground structure comprises a base layer 1.

[0026] In this implementation scheme: the existing {public announcement number}: CN216041365U discloses a water discharge and pressure relief structure used for basement anti-floating. This patent discloses a foundation. The base layer 1 in the present application document adopts the same technical means in this prior art. This technical means will not be described one by one here. For details about the improvement of this prior art, please refer to the disclosed technology below; to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the device lacks a filtering function. When the water under the base layer 1 is discharged, the impurities inside it may cause equipment failure, thereby affecting its service life, and also causing water accumulation in the basement and resulting in property loss". In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve the above problems, an installation pipe 2 and a water-permeable trough 3 are added on this basis.

[0027] More specifically:

[0028] like Figure 1 - Figure 5 As shown:

[0029] In combination with the above content: it also includes an installation pipe 2, a permeable groove 3, a water filter pipe 4, a water filter groove 5, a filter element 6, a drain valve 7 and a water pump 8 arranged on one side of the base layer 1, the inner surface of the base layer 1 is fixedly installed with the installation pipe 2, and the surface of the installation pipe 2 is provided with a permeable groove 3, and the inner surface of the installation pipe 2 is also slidably connected to the surface of the water filter pipe 4, the surface of the water filter pipe 4 is provided with a water filter groove 5, and the water filter groove 5 and the filter element 6 are fittedly connected, and the end of the water filter pipe 4 away from the installation pipe 2 is fixedly connected to the drain valve 7, and one side of the drain valve 7 is also provided with a water pump 8 fixedly connected to the surface of the base layer 1.

[0030] In this embodiment: when a large amount of water infiltrates into the bottom of the base layer 1, the water flow will penetrate through the base layer 1 to the position of the mounting tube 2 and reach the position of the water filter pipe 4 and the filter element 6 through the water permeable groove 3 opened on the surface of the mounting tube 2. At this time, the filter element 6 installed inside the water filter groove 5 will filter the water flow and pump it to the inside of the base layer 1 through the drain valve 7. Then the water pump 8 can be started to discharge the water inside the base layer 1. When the filter element 6 may be blocked after filtering for a period of time, the water filter pipe 4 and the drain valve 7 can be rotated 30 degrees. During this process, the blocked filter element 6 will rotate to the inside of the mounting tube 2, and a part of the clean filter element 6 originally located on the inside of the mounting tube 2 will be rotated to the position of the water permeable groove 3 and overlap with the water permeable groove 3. At this time, the clean filter element 6 will continue to filter and control impurities in the water, thereby reducing the load of the water pump 8 and increasing its service life.

[0031] Going further:

[0032] In an optional embodiment, the shape of the installation tube 2 is a hollow cylinder, and the inner surface diameter of the installation tube 2 is the same as the diameter of the water filter tube 4 .

[0033] In this embodiment: by installing the pipe 2 and the water filter pipe 4 with the same diameter, stable rotation of the two can be achieved, so that the alternating filtering work of the filter element 6 installed on the surface of the water filter pipe 4 can be stably realized, and further ensure that the alternating work can be carried out quickly when a part of the filter element 6 is blocked.

[0034] Going further:

[0035] In an optional embodiment, the water-permeable grooves 3 are opened at equal angles on the surface of the mounting pipe 2, and a total of six water-permeable grooves 3 are provided.

[0036] In this embodiment: the water-permeable grooves 3 opened at equal angles on the surface of the mounting tube 2 can enable the water-filter grooves 5 and the filter element 6 to be connected with the water-permeable grooves 3 opened on the surface of the mounting tube 2 before and after the water-filter tube 4 and the filter element 6 are rotated, thereby ensuring that the filtering work of the filter element 6 can be carried out stably.

[0037] Going further:

[0038] In an optional embodiment, the filter grooves 5 are opened at equal angles on the surface of the filter pipe 4, and the angle between each filter groove 5 is 30 degrees.

[0039] In this embodiment: the water filter grooves 5 opened at equal angles can simultaneously drive the filter element 6 and the water-permeable grooves 3 opened on the surface of the mounting tube 2 to be misaligned when the water filter pipe 4 drives it to rotate, thereby enabling the filter element 6 installed inside the water filter grooves 5 to achieve alternating filtering work.

[0040] Going further:

[0041] In an optional embodiment, the filter element 6 is in the shape of a fan-shaped column, and the filter element 6 and the water filter tank 5 have the same shape.

[0042] In this embodiment: the filter element 6 having the same shape as the water filter trough 5 can form a complete cylinder when connected to the water filter pipe 4 and the water filter trough 5, so that when the water enters the water filter pipe 4 through the installation pipe 2 and the permeable groove 3, it can be filtered by the filter element 6, and the pumping pressure of the water pump 8 can be reduced, so that the service life of the water pump 8 can be extended.

[0043] Going further:

[0044] In an optional embodiment, the height of the drain valve 7 is higher than the height of the water pump 8 , and the water pump 8 is close to the bottom surface of the base layer 1 .

[0045] In this embodiment: the water pump 8 below the drain valve 7 can smoothly discharge the water through the drain valve 7 when the drain valve 7 discharges the water into the interior of the base layer 1, thereby ensuring that the water inside the space can be smoothly pumped out, thereby preventing the water outside the building from penetrating into the interior.

[0046] The working principle and use process of the utility model are as follows: when a large amount of water infiltrates into the bottom of the base layer 1, the water flow will penetrate through the base layer 1 to the position of the installation pipe 2 and reach the position of the water filter pipe 4 and the filter element 6 through the water permeable groove 3 opened on the surface of the installation pipe 2. At this time, the filter element 6 installed inside the water filter groove 5 will filter the water flow and pump it to the inside of the base layer 1 through the drain valve 7. Then the water pump 8 can be started to discharge the water inside the base layer 1. When the filter element 6 may be blocked after filtering for a period of time, the water filter pipe 4 and the drain valve 7 can be rotated 30 degrees. During this process, the blocked filter element 6 will rotate to the inside of the installation pipe 2, and a part of the clean filter element 6 originally located on the inside of the installation pipe 2 will be rotated to the position of the water permeable groove 3 and overlap with the water permeable groove 3. At this time, the clean filter element 6 will continue to filter and control impurities in the water, thereby reducing the load of the water pump 8 and increasing its service life.

[0047] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
