[0036] The technical solution of the present utility model embodiment is described in detail below with reference to the accompanying drawings. The spray device for sedimentation tank includes: a water collection tank 5 installed on the sedimentation tank, a booster pump 1 configured below the water collection tank 5, and a spray pipe 2 connected to the booster pump 1. The water collection tank 5 can continuously collect water to provide a stable water source for cleaning the sedimentation tank.

[0037] The water source in the water collection tank 5 is pressurized by the booster pump 1 and then input into the spray pipe 2, so that the multiple spray holes 21 of the spray pipe 2 can have sufficient output water pressure to achieve a large-area spraying effect.

[0038] A pressurizing mechanism 3 is provided at the end output position of the spray pipe 2. The pressurizing mechanism 3 includes a pressurizing gear set 31 and a pressurizing valve 33. The water flow inside the spray pipe 2 is pressurized by the pressurizing gear set 31 and then outputs pressurized water flow from the pressurizing valve 33 at the end of the spray pipe 2.

[0039] The water flow at the end of the spray pipe 2 is pressurized by the booster gear set 31, so that the output water pressure at the end of the spray pipe 2 meets the requirements for flushing away stubborn moss.

[0040] The beneficial effects of this embodiment:

[0041] In this technical solution, a booster pump 1 is installed in the water collection tank 5. The booster pump 1 increases the water pressure of the water flow inside the spray pipe 2, thereby achieving overall pressurization. This ensures that the water pressure at the outlet of the spray hole 21 meets the spraying requirements, improving the spraying and rinsing effect and removing low-viscosity moss and sludge. Then, based on the booster mechanism 3 at the end of the spray pipe 2, the water pressure at the end is further increased to achieve local pressurization, meeting the rinsing requirements of stubborn moss and sludge. The gradation pressurization meets the rinsing pressure requirements of different cleaning objects.

[0042] Specifically, the booster pump 1 is equipped with a drive motor, and the sedimentation tank is equipped with an electrical connection mechanism. The drive motor is electrically connected to an external power supply based on the electrical connection mechanism. The booster pump 1 is driven by the drive motor to extract water from the water collection tank 5 and supply it to the spray pipe 2 by pressurization to meet the long-distance transportation needs of the spray pipe 2.

[0043] By using an electric booster pump 1, the overall configuration of the booster pump 1 can be simplified, making the sedimentation tank spray device simple in structure and easy to install and maintain.

[0044] Specifically, the power supply mechanism includes a sliding contact line 41 and a copper brush. The sedimentation tank is also equipped with a wire groove 4, in which the sliding contact line 41 is installed. The copper brush is fixed on the water collection tank 5 and slides in contact with the sliding contact line 41. The output end of the copper brush is electrically connected to the drive motor. The sliding contact line 41 is embedded in the wire groove 4. Based on the fact that the sliding contact line 41 is electrically connected to an external power supply with a working voltage of 220V, the 220V working voltage can meet the electrical drive requirements of the booster pump 1 motor. Furthermore, the cooperation between the sliding contact line 41 and the copper brush allows for a flexible power connection structure configuration for the sedimentation tank spraying device.

[0045] Specifically, the sedimentation tank is equipped with a sludge scraper to scrape off and clean the moss on the inner wall of the sedimentation tank. The water collection trough 5 is connected to the steel frame structure of the sludge scraper, and the water collection trough 5 rotates with the sludge scraper, that is, the copper brush can rotate with the water collection trough 5. Based on the sliding cooperation between the copper brush and the sliding contact line 41, the rotational movement requirements of the copper brush are met.

[0046] Specifically, the end of the spray pipe 2 is provided with several spray holes 21. The several spray holes 21 are evenly arranged along the axial direction of the spray pipe 2. Based on the multiple spray holes 21, the spray pipe 2 can form a large area spraying effect in the axial direction.

[0047] Specifically, the end of the spray pipe 2 is provided with a receiving cavity to accommodate the booster gear set 31, and the receiving cavity is divided into a booster cavity 35 and an output cavity 36 based on the booster gear set 31. By dividing the booster cavity 35 and the output cavity 36, the end water flow is filled in the booster cavity 35 and the output cavity 36, and the output water flow is boosted based on the gear movement, which can achieve high-efficiency boosting.

[0048] The pressurizing mechanism 3 is provided with an input port 32, which is connected to the pressurizing chamber 35, so that the water flow inside the spray pipe 2 can flow into the pressurizing chamber 35 through the input port 32. The opening connecting the pressurizing chamber 35 and the pressurizing gear set 31 is larger than the opening connecting the pressurizing gear set 31 and the output chamber 36, so that after the pressurizing is boosted by the rotation of the pressurizing gear set 31, the pressurized water flow can fill the output chamber 36.

[0049] Specifically, the booster gear set 31 includes a driving gear 311 and a driven gear 312. The driving gear 311 and the driven gear 312 mesh with each other, and the driving gear 311 rotates counterclockwise while the driven gear 312 rotates clockwise. This causes the side connected to the booster chamber 35 to move away from each other based on the driving gear 311 and the driven gear 312, forming a low-pressure water flow that drives the water flow to be transported along the side wall of the gears. The side of the driving gear 311 and the driven gear 312 connected to the output chamber 36 moves closer to each other and meshes, forming a high-pressure water flow that is transported to the output chamber 36.

[0050] Furthermore, a drive mechanism is provided on the outside of the spray pipe 2. The drive mechanism drives the active gear 311 to rotate, which in turn drives the driven gear 312 to rotate. This allows the booster gear set 31 to continuously draw in and output water, so that the end of the spray pipe 2 can achieve a stable output effect, and the water flow at the end of the spray pipe 2 can have a suitable output pressure for flushing.

[0051] Specifically, the booster valve 33 is hinged to the end of the spray pipe 2, and a torsion spring 34 is configured on the outside of the booster valve 33. Based on the torsion spring 34, the booster valve 33 is in the closed state. When the water flow pressure at the end of the spray pipe 2 is greater than the torsion of the torsion spring 34 of the booster valve 33, the water flow output at the end of the spray pipe 2 can achieve the effect of high-pressure flushing.

[0052] Furthermore, when the pressure boosting valve 33 is squeezed by the water flow in the output chamber 36 and overcomes the torque of the torsion spring 34, the static pressure of the water flow at the end of the spray pipe 2 overcomes the torque of the torsion spring 34, causing the pressure boosting valve 33 to open and maintaining a stable dynamic pressure of the water flow at the end of the spray pipe 2 to spray out from the pressure boosting valve 34, thereby achieving the effect of washing away stubborn moss and silt.

[0053] The working principle of this technical solution is as follows: Rainwater collected in the water collection tank 5 and greywater from the sedimentation tank are used to provide cleaning water to the sedimentation tank spraying device. An electric booster pump 1, located below the water collection tank 5, pressurizes the water flow and supplies it to the spray pipe 2. This ensures that the water pressure inside the spray pipe 2 meets the spraying requirements of several spray holes 21, resulting in sufficient water pressure for a large-area spraying effect. A booster gear set 31 at the end of the spray pipe 2 further compresses and pressurizes the water flow, driving a booster valve 33 to achieve a pressurized output at the end of the spray pipe 2. This higher pressure water flow washes away stubborn moss and silt.
