Description

Technical Field

[0001] The utility model relates to the technical field of ventilation and filtration, in particular to a ventilation unit filtration structure of a transformer substation. Background Art

[0002] In the power system, substations are key nodes for power conversion and distribution, and their stable operation is crucial. The equipment within substations generates a large amount of heat during operation, which requires ventilation systems to dissipate heat to ensure the equipment's normal operating temperature. However, substations are typically located outdoors or in relatively open environments. Airborne impurities such as dust and particulate matter can enter the substation through ventilation airflow, contaminating the equipment and potentially causing faults such as short circuits and overheating, seriously impacting the substation's safe operation.

[0003] While traditional substation ventilation unit filtration structures can block dust and particulate matter to a certain extent, they suffer from several significant drawbacks. First, after prolonged use, the filters are prone to accumulating large amounts of dust particles, which reduces filtration efficiency and can even clog ventilation ducts, affecting ventilation effectiveness. Second, these accumulated dust particles typically require regular manual cleaning, which not only increases maintenance costs but also can cause secondary contamination or damage to equipment during the cleaning process. Furthermore, traditional filtration structures often lack effective self-cleaning mechanisms, making it impossible to remove dust particles from the filters in real time, resulting in a gradual decrease in filtration effectiveness over time.

[0004] In response to the above problems, the utility model proposes a new substation ventilation unit filtration structure, which aims to achieve automatic cleaning of the filter through an innovative self-cleaning mechanism, reduce the frequency and difficulty of manual cleaning, and at the same time ensure continuous and efficient filtration of the filter to ensure the safe and stable operation of the substation. Utility Model Content

[0005] In order to overcome the problem that the filter screen of the traditional substation ventilation unit filter structure is prone to accumulate a large amount of dust particles after long-term use, resulting in a decrease in filtration efficiency and even clogging of the ventilation duct, affecting the ventilation effect; and the accumulated dust particles usually need to be manually cleaned regularly, which not only increases maintenance costs, but also may cause secondary pollution or damage to the equipment during the cleaning process; at the same time, traditional filter structures often lack effective self-cleaning mechanisms and cannot remove dust particles on the filter screen in real time, resulting in the problem that the filtration effect gradually decreases over time.

[0006] The technical solution of the utility model is: a substation ventilation unit filtering structure, comprising a mounting frame, a ventilation pipe, a primary filter assembly, a filter assembly, a fixing assembly, a discharge assembly and a material guide assembly; a ventilation pipe is arranged on the inner side of the mounting frame, two groups of ventilation pipes are arranged, a primary filter assembly is arranged at one end of the ventilation pipe, a filter assembly is arranged at the inner side of the ventilation pipe, a fixing assembly is arranged at the inner side of the ventilation pipe, a discharge assembly is arranged below the ventilation pipe, and a material guide assembly is arranged at the inner side of the discharge assembly; the filter assembly comprises a filter screen, a fixing frame, a fixing column, a connecting ring, a connecting rope and metal beads; a filter screen is arranged at the inner side of the ventilation pipe, a fixing frame is arranged at the inner side of the fixing frame, a connecting ring is arranged at the outer side of the fixing column, the connecting ring and the fixing column are rotatably connected, a connecting rope is arranged below the connecting ring, and a metal bead is arranged at one end of the connecting rope.

[0007] Preferably, fine dust particles are filtered through the filter, the position of the fixing column is fixed by the fixing frame, and the position of the connecting ring is fixed by the fixing column. When the filtering structure and the ventilation unit work together, the airflow flows through the ventilation pipe and drives the connecting rope to shake, and the shaking of the connecting rope drives the metal beads to shake. When the metal beads shake, they will continuously hit the filter, causing the filter to vibrate. The vibration of the filter will shake off the dust particles accumulated on the filter, thereby performing self-cleaning on the filter and reducing the frequency and difficulty of manual cleaning.

[0010] Preferably, the fixing assembly further includes a connecting plate and an anti-slip pad; a connecting plate is provided at one end of the electric telescopic rod, and an anti-slip pad is provided on one side of the connecting plate.

[0011] Preferably, the discharging assembly includes a discharging rack and a discharging port; the discharging rack is provided below the ventilation pipe, and the discharging port is provided below the discharging rack.

[0012] Preferably, the material guiding assembly includes a motor and a rotating shaft; the motor is provided on one side of the discharging rack, and the rotating shaft is provided on the output end of the motor.

[0013] Preferably, the material guiding assembly further comprises an auger; an auger is provided on the outer side of the rotating shaft.

[0014] Beneficial effects of the utility model:

[0015] 1. Compared with the traditional substation ventilation unit filter structure, which often requires manual regular cleaning to remove dust particles accumulated on the filter screen, the utility model utilizes the shaking of the connecting rope driven by the air flow through the ventilation pipe, thereby causing the metal beads to generate impact force, continuously knocking on the filter screen, thereby realizing the function of automatically shaking off dust particles. This self-cleaning mechanism significantly reduces the frequency and difficulty of manual cleaning, while ensuring the continuous and efficient filtration of the filter screen, and extending the service life of the filter structure.

When in use, the primary filter holes 102 on the primary filter plate 101 can initially block large particles of dust, reduce the filtering burden of the built-in filter structure, and extend the service life of the filter structure. The fixing assembly includes a fixing block 301 and an electric telescopic rod 302; a fixing block 301 is provided on one side of the ventilation pipe 2, and an electric telescopic rod 302 is provided on the inner side of the fixing block 301.

When in use, the connecting plate 303 is driven to move linearly by the telescopic movement of the electric telescopic rod 302, and the anti-skid pad 304 is driven to move linearly by the linear movement of the connecting plate 303. The two groups of anti-skid pads 304 follow the linear movement of the connecting plate 303 to clamp and fix the metal beads 206, so as to prevent the metal beads 206 from swinging with the airflow and hitting the filter screen 201 to generate noise when self-cleaning is not required.

[0024] The discharge assembly includes a discharge rack 401 and a discharge port 402; the discharge rack 401 is provided below the ventilation pipe 2, and the discharge port 402 is opened below the discharge rack 401, and the material guide assembly includes a motor 501 and a rotating shaft 502; a motor 501 is provided on one side of the discharge rack 401, and a rotating shaft 502 is provided at the output end of the motor 501, and the material guide assembly also includes an auger 503; an auger 503 is provided on the outside of the rotating shaft 502.

[0025] During operation, the primary filter holes 102 on the primary filter plate 101 can initially block large particles of dust, thereby reducing the filtering burden of the built-in filter structure.

When the metal beads 206 shake, they continuously hit the filter 201, causing the filter 201 to vibrate. The vibration of the filter 201 shakes off the dust particles accumulated on the filter 201.

[0027] After the dust particles are shaken off the filter 201, they are guided into the inner side of the discharge rack 401 through the curved inner wall of the ventilation pipe 2 when the dust particles on the filter 201 fall. The rotating shaft 502 is driven to rotate by starting the motor 501, and the auger 503 is driven to rotate by the rotation of the rotating shaft 502.

[0028] Through the above steps, the filter 201 is used to filter fine dust particles, the fixing frame 202 is used to fix the position of the fixing column 203, and the fixing column 203 is used to fix the position of the connecting ring 204. When the filtering structure and the ventilation unit work together, the airflow flows through the ventilation pipe 2 and drives the connecting rope 205 to shake. The shaking of the connecting rope 205 drives the metal beads 206 to shake. When the metal beads 206 shake, they will continuously hit the filter 201, causing the filter 201 to vibrate. The vibration of the filter 201 will shake off the dust particles accumulated on the filter 201 from the filter 201, thereby performing self-cleaning on the filter 201 and reducing the frequency and difficulty of manual cleaning.
