Technical Field

[0001] This utility model belongs to the field of substation drainage technology, specifically relating to an integrated small drainage device for substations. Background Technology

[0002] During the flood season and periods of heavy rainfall, substations and their drainage systems may accumulate a large amount of impurities due to prolonged exposure to the environment, which can easily lead to blockages during the drainage process.

[0003] In the prior art, Chinese utility model patent document with authorization announcement number CN218438517U discloses a drainage device for substations, which is equipped with a water collection plate, a treatment box and a drainage pipe. It can collect, treat and discharge rainwater flowing down from a height, preventing rainwater from splashing into the substation's power distribution room or transformer room, causing water accumulation and affecting equipment operation. However, the filter plate has a limited filtration area, and after a period of use, impurities easily adhere to the filter plate, affecting water flow and requiring frequent cleaning. Furthermore, it is not easy to directly brush the filter side of the filter plate during cleaning, making it difficult to remove the adhered impurities.

[0004] Therefore, it is necessary to design an integrated small-scale drainage device for substations that increases the filtration area, reduces the frequency of cleaning and maintenance, ensures the filtration effect, and facilitates direct cleaning of the filter side to solve the current technical problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an integrated small-scale drainage device for substations that increases the filtration area, reduces the frequency of cleaning and maintenance, ensures filtration effectiveness, and facilitates direct cleaning of the filter side.

[0006] The technical solution of this utility model is as follows: an integrated small drainage device for substations, including a filter chamber with a cylindrical cavity structure, a filter cylinder fixedly installed coaxially inside the filter chamber, filter holes evenly opened around the circumference of the filter cylinder, a support cylinder fixedly installed at the top of the filter chamber corresponding to and connected to the filter cylinder, a water inlet pipe connected to one side of the support cylinder, a cleaning pipe fixedly installed at the bottom of the filter chamber corresponding to and connected to the filter cylinder, and a bottom cover detachably fixedly installed at the bottom end of the cleaning pipe; a drainage trough fixedly installed and connected to one side of the filter chamber, and a drain pipe fixedly installed at the bottom end of the drainage trough.

[0007] The support cylinder and the filter cylinder are equipped with a filter cylinder cleaning mechanism for cleaning the filter cylinder.

[0008] The filter cylinder has a rotating shaft inside and rotates along its axis. A cleaning plate that matches the inner wall of the filter cylinder is fixedly mounted on the outside of the rotating shaft by a support strip. A handwheel is fixedly mounted on the top of the rotating shaft.

[0009] Brush bristles are fixedly installed on the side of the cleaning plate corresponding to the inner wall of the filter cylinder.

[0010] A support top plate is fixedly installed at the top of the support cylinder, and the rotating shaft is rotatably connected to the support top plate. A cross bracket is fixedly installed at the bottom of the filter cylinder, and the rotating shaft is rotatably connected to the cross bracket.

[0011] The top of the bottom cover is fixedly provided with an internally threaded connecting pipe that is threaded to the inside of the cleaning pipe.

[0012] A handle is fixedly installed at the bottom of the bottom cover.

[0013] The bottom end of the cleaning tube is fixedly provided with a sealing ring corresponding to the bottom cover.

[0014] The beneficial effects of this utility model are:

[0015] (1) In this utility model, the filter cylinder has a large filtration area and a certain height. After impurities enter its interior, they will gradually accumulate from the bottom to the top under the flushing of water. After the impurities are generated, the upper section of the filter cylinder still has a large effective filtration area, ensuring the filtration effect and reducing the frequency of cleaning and maintenance.

[0016] (2) When cleaning is required, open the bottom cover. Some of the impurities in the filter cylinder will fall out directly under the action of gravity. Then, a brush can be used to clean the filter side of the filter cylinder to ensure the cleaning effect of the filter cylinder. Attached Figure Description

[0023] like Figures 1 to 4 As shown, an integrated small-scale drainage device for substations is disclosed, including a filter chamber 1 with a cylindrical cavity structure. A filter cylinder 13 is fixedly installed coaxially inside the filter chamber 1. Filter holes 14 are evenly distributed around the filter cylinder 13. A support cylinder 5, corresponding to and connected to the filter cylinder 13, is fixedly installed at the top of the filter chamber 1. A water inlet pipe 2, connected to the support cylinder 5, is installed on one side of the support cylinder 5. A cleaning pipe 11, corresponding to and connected to the filter cylinder 5, is fixedly installed at the bottom of the filter chamber 1. A bottom cover 12 is detachably fixed at the bottom end of the cleaning pipe 11. A drainage trough 4, connected to the filter chamber 1, is fixedly installed on one side of the filter chamber 1. A drain pipe 3 is fixedly installed at the bottom end of the drainage trough 4. In this embodiment, the top end of the water inlet pipe 2 is connected to the bottom of a water collection plate on the top of the substation. Water accumulated in the water collection plate flows into the water inlet pipe 2. Water enters the support cylinder 5 through the inlet pipe 2 and falls into the filter cylinder 13. The filter cylinder 13 retains impurities inside, while the accumulated water passes through the filter holes 14 into the space between the filter chamber 1 and the filter cylinder 13. It then enters the drainage trough 4 and is discharged outward from the drain pipe 3 at its bottom. The filter cylinder 13 has a large filtration area and a certain height. After impurities enter its interior, they will gradually accumulate from the bottom to the top under the flushing of the water flow. Even after impurities are generated, the upper section of the filter cylinder 13 still has a large effective filtration area, ensuring the filtration effect and reducing the frequency of cleaning and maintenance. When cleaning is required, the bottom cover 12 is opened, and some of the impurities in the filter cylinder 13 fall out directly under the action of gravity. Then, a brush can be used to clean the filter side of the filter cylinder 13 to ensure the cleaning effect of the filter cylinder 13.

[0024] In some embodiments, the support cylinder 5 and the filter cylinder 13 are provided with a filter cylinder cleaning mechanism 6 for cleaning the filter cylinder 13. The filter cylinder cleaning mechanism 6 can clean the inside of the filter cylinder 13 without the need to prepare a brush to clean the inside of the filter cylinder 13, thus improving the convenience of maintenance.

[0025] In some embodiments, a rotating shaft 62 is rotatably mounted inside the filter cylinder 13 along its axial direction. A cleaning plate 61 matching the inner wall of the filter cylinder 13 is fixedly mounted on the outer side of the rotating shaft 62 by a support strip 64. A handwheel 63 is fixedly mounted on the top of the rotating shaft 62. When the bottom cover 12 is open, the rotating shaft 62 is rotated by the handwheel 63. The rotating shaft 62 drives the cleaning plate 61 to rotate inside the filter cylinder 13 through the support strip 64, thereby cleaning the inside of the filter cylinder 13. There is no need to prepare a brush to clean the inside of the filter cylinder 13, which improves the convenience of maintenance.

[0026] In some embodiments, such as Figure 4 As shown, a brush bristle 66 is fixedly installed on the side of the cleaning plate 61 corresponding to the inner wall of the filter cylinder 13. The brush bristle 66 can better remove impurities in the filter hole 14 and improve the cleaning effect. Specifically, the brush bristle 66 is made of nylon filaments.

[0027] In some embodiments, a support top plate 51 is fixedly provided at the top of the support cylinder 5, and the rotating shaft 62 is rotatably connected to the support top plate 51. A cross bracket 65 is fixedly provided at the bottom of the filter cylinder 13, and the rotating shaft 62 is rotatably connected to the cross bracket 65. The upper end of the rotating shaft 62 is rotatably supported by the support top plate 51, and the lower end of the rotating shaft 62 is rotatably supported by the cross bracket 65, thus ensuring the stability of the rotating shaft 62.

[0028] In some embodiments, the top of the bottom cover 12 is fixedly provided with an internally threaded connecting pipe 122 that is internally threaded to the cleaning pipe 11. The bottom cover 12 can be removed from the bottom end of the cleaning pipe 11 or reinstalled at the bottom end of the cleaning pipe 11 by screwing on the bottom cover 12.

[0029] In some embodiments, a handle 121 is fixedly provided on the bottom of the bottom cover 12, and the bottom cover 12 can be easily screwed on by means of the handle 121. The handle 121 is a strip-shaped protrusion structure that is integral with the bottom of the bottom cover 12.

[0030] In some embodiments, a sealing ring 123 corresponding to the bottom cover 12 is fixedly provided at the bottom end of the cleaning tube 11. The sealing ring 123 can improve the sealing between the bottom cover 12 and the cleaning tube 11 and prevent water leakage between the bottom cover 12 and the cleaning tube 11.
