Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features.

[0042] See also Figures 1 to 3The utility model provides an integrated pump station for dredging, which includes a pump station shell 1, an inlet pipe 2, an outlet pipe 3 and a rotary flushing unit 4. Specifically, a sewage holding chamber suitable for holding sewage is formed in the pump station shell 1, and a water inlet, a water outlet and a sewage outlet are formed on the pump station shell 1. The inlet pipe 2 can extend from the water inlet into the sewage holding chamber to guide the sewage into the sewage holding chamber, and the outlet pipe 3 extends from the water outlet into the sewage holding chamber to guide the sewage from the sewage holding chamber to the outside of the integrated pump station, and the sludge formed by the precipitation of sewage in the sewage holding chamber can be discharged through the sewage outlet, so that the sewage holding chamber can maintain an effective storage volume.

[0043] It should be noted that a first branch pipe 21 and a second branch pipe 22 may be provided at one end of the water inlet pipe 2 located in the sewage holding chamber, and a selection valve 23 is provided on the main pipe of the water inlet pipe 2 located in the sewage holding chamber, so that the main pipe can be selectively connected to the first branch pipe 21 or the second branch pipe 22 via the selection valve 23, and the water outlet end of the second branch pipe 22 is connected to the rotary flushing unit 4, and the sewage enters the rotary flushing unit 4 from the second branch pipe 22 and flows out from the water outlet end of the rotary flushing unit 4 to form a flushing jet directed toward the bottom of the sewage holding chamber, and the rotary flushing unit 4 can rotate under the drive of the water flow in the second branch pipe 22 to drive the contact point between the flushing jet and the bottom of the sewage holding chamber to rotate circumferentially around the bottom of the sewage holding chamber.

[0044] Based on the above structure, when the main pipeline is connected to the first branch pipe 21, the sewage can flow directly into the sewage holding chamber. When the sludge in the sewage holding chamber reaches the amount that needs to be cleaned, the main pipeline can be connected to the second branch pipe 22, so that the rotary flushing unit 4 can rotate under the drive of the water flow in the second branch pipe 22, so as to drive the contact point between the flushing jet and the bottom of the sewage holding chamber to rotate circumferentially around the bottom of the sewage holding chamber, so as to fully flush the sludge deposited at the bottom of the sewage holding chamber, so that the sludge can be diluted and discharged from the sewage outlet, thereby realizing dredging of the integrated pump station. In the dredging process, only the kinetic energy of the sewage flowing into the sewage holding chamber is needed to achieve flushing and dredging, without the need to introduce other energy from the outside, thereby reducing the overall energy consumption of the integrated pump station.

[0045] In addition, a flow detector (not shown in the figure) can be set on the water inlet pipe 2 and the water outlet pipe 3, so that the sludge content in the sewage holding chamber can be known through the flow difference between the water inlet pipe 2 and the water outlet pipe 3 and the flow monitoring time, so as to clean the sludge in time.

[0046] Furthermore, a partition 5 can be arranged in the sewage holding chamber to separate the sewage holding chamber into an upper maintenance space and a lower silt storage space via the partition 5, wherein the lower silt storage space is used to store sewage, and the upper maintenance space can allow maintenance personnel to enter the integrated pump station, and the partition 5 can be used as a maintenance platform. It can be understood that the water inlet should be connected to the silt storage space to discharge the sewage directly into the silt storage space, and a water level monitor 8 suitable for detecting the water level in the silt storage space can be arranged in the silt storage space. The water level monitor 8 can be an infrared distance sensor, which can be arranged below the partition 5 to monitor the liquid level of the sewage. An infrared distance sensor (or the distance of the partition 5, to ensure that the sewage does not flood the partition 5), to ensure that the sewage does not flood the partition 5, the water outlet is connected to the maintenance space, the water outlet end of the outlet pipe 3 is connected to the water outlet, the water inlet end of the outlet pipe 3 passes through the partition 5 and extends into the silt storage space to facilitate the extraction of sewage in the silt storage space, and a water pump 31 is connected to the portion of the outlet pipe 3 in the maintenance space. During maintenance, maintenance personnel can stand on the maintenance platform for maintenance, so that they are not easily exposed to sewage, and the water pump 31 is arranged in the maintenance space, which can make the water pump 31 less susceptible to erosion by sewage and can also facilitate maintenance personnel to repair the water pump 31.

[0048] It is understandable that a ventilation port 12 connected to the maintenance space needs to be opened on the pump station shell 1 to allow fresh air from the outside to enter the maintenance space, to prevent the sludge in the silt storage space from accumulating for a long time and consuming the oxygen in the sewage holding chamber or producing a foul odor, so as to avoid suffocation of maintenance personnel and improve the maintenance work environment. Preferably, a ventilation duct 121 can be connected to the ventilation port 12, and the end of the ventilation duct 121 away from the ventilation port 12 extends toward the partition 5, and a blower is also provided in the ventilation port 12 or the ventilation duct 121, so as to actively blow air into the maintenance space or draw air from the maintenance space before and during maintenance, so as to realize a large circulation from the maintenance port 11 to the partition 5 and then to the ventilation port 12, which can have a better ventilation effect.

[0049] Furthermore, a coarse filter chamber 25 suitable for accommodating a coarse filter grid cage 24 is formed in the main pipe of the water inlet pipe 2 in the sewage holding chamber, and an insertion port connected to the coarse filter chamber 25 is opened at the upper part of the main pipe. The coarse filter grid cage 24 can be inserted into the coarse filter chamber 25 from the insertion port, and a sewage inlet 241 connected to the water inlet is opened on the coarse filter grid cage 24, so that sewage can enter the coarse filter grid cage 24 through the sewage inlet 241, so that large particles of impurities (for example, impurities with a diameter of more than 10 mm) in the sewage can be filtered out by the coarse filter grid cage 24, thereby reducing the situation where large particles of impurities block the water outlet pipe 3, the rotary flushing unit 4 and the sewage outlet.

[0050] It is understandable that if Figure 3 and Figure 4 As shown, a pair of relatively arranged tracks 7 can be further arranged in the sewage holding chamber, one end of the track 7 is inserted into the coarse filter chamber 25, the other end of the track 7 is connected to the top wall of the pump station shell 1, and a withdrawal port 13 is opened at a position corresponding to the track 7 on the top wall of the pump station shell 1, and a track 7 groove matching the track 7 is formed on the coarse filter grid cage 24, and a pulling rope (not shown in the figure) is connected to the coarse filter grid cage 24, the pulling rope can be extended from the pump station shell 1 from the withdrawal port 13, and the coarse filter grid cage 24 can be moved up along the track 7 and pass through the withdrawal port 13 under the traction of the pulling rope, so that the maintenance personnel can take out the coarse filter grid cage 24 without entering the sewage holding chamber, thereby facilitating the dumping of large particles of impurities in the coarse filter grid cage 24.

[0051] Furthermore, if Figure 5 As shown, the rotary flushing unit 4 may specifically include a volute 41, a rotating shaft 42 and a water outlet head 43. The water inlet end of the volute 41 is connected to the second branch pipe 22, the rotating shaft 42 is rotatably connected to the volute 41 and passes through the water outlet end of the volute 41 to be connected to the water outlet head 43, the water outlet end of the volute 41 is located at the lower part of the volute 41, the water outlet head 43 is located below the volute 41, and a fan blade structure 421 is provided on the rotating shaft 42. The sewage flows from the water inlet end of the volute 41 through the fan blade structure 421 and the water outlet end of the volute 41 in sequence and flows out from the water outlet head 43 to form a flushing jet, and when the sewage flows through the fan blade structure 421, it can drive the rotating shaft 42 to rotate along its own axial direction, thereby realizing the rotation of the water outlet head 43 and then realizing the circumferential rotation of the contact point between the flushing jet and the bottom of the sewage holding chamber around the bottom of the sewage holding chamber, so that the sludge at the bottom of the sewage holding chamber can be more evenly flushed and diluted, thereby having a better dredging effect.

[0052] It can be understood that a plurality of water diversion ports 431 are arranged along the circumference of the water outlet head 43, and the sum of the flow areas of the plurality of water diversion ports 431 can be set to be 60% to 90% of the flow area of ​​the second branch pipe 22, so that the sewage can have a higher water pressure when flowing out from the water diversion ports 431, thereby having a better flushing effect, and setting up a plurality of water diversion ports 431 can make the flushing efficiency higher.
