[0028] The embodiment of the present application proposes an efficient flushing device for moss at the cofferdam of the secondary sedimentation tank. When in use, the flushing device is installed on the first side wall 01. Taking a mounting plate 1 as an example, at this time, the walking wheel 2 is in conflict with the side of the first side wall 01 facing the mounting plate 1, and the positioning component 3 is in conflict with the inner and outer peripheries of the first side wall 01, that is, this mounting plate 1 is "clamped" to the first side wall 01 through the positioning component 3 and the walking wheel 2. Multiple mounting plates 1 are connected to the first side wall 01 in the above manner, and multiple mounting plates 1 are arranged in sequence along the circumference of the first side wall 01. After the flushing device is connected to the first side wall 01, the driving member 5 can be started. The driving member 5 drives a walking wheel 2 to rotate through the transmission assembly 4. When the walking wheel 2 rotates, it drives the corresponding mounting plate 1 and other mounting plates 1 to move along the circumference of the first side wall 01. When each mounting plate 1 moves, the water outlet cofferdam can be flushed through the flushing assembly 6. The flushing device can rotate around the water outlet cofferdam alone to flush the moss. Compared with relying on the rotation of the scraper to drive the rotation of the flushing device, the flushing device of the present application is easy to operate as a whole and has low energy consumption.

[0029] It should be understood that the second sedimentation tank is in the shape of a ring, that is, the first side wall 01 and the second side wall 02 of the outlet cofferdam are both in the shape of a ring, then the first side wall 01 has a circumferential direction and a radial direction, and the first side wall 01 is located outside the second side wall 02; in addition, the axial directions of the first side wall 01 and the second side wall 02 should coincide and be the same as the direction of gravity, then the above-mentioned mounting plate 1 is arranged above the first side wall 01, it can be clearly understood that the mounting plate 1 is located above the first side wall 01 in the direction of gravity.

[0030] Each mounting plate 1 is connected to the first side wall 01 via a walking wheel 2 and a set of positioning components 3. The more mounting plates 1 there are, the more stable the flushing device moves on the first side wall 01.

[0031] Furthermore, two rotating rods 9 are arranged between every two mounting plates 1. The two rotating rods 9 are rotatably connected by a pin shaft. The axial direction of the pin shaft is the same as the thickness direction of the mounting plate 1. At this time, the mounting plate 1 has the freedom to rotate around its own thickness direction. In this way, when multiple mounting plates 1 are connected to the first side wall 01, the multiple mounting plates 1 can be arranged at intervals along the circumference of the first side wall 01. At the same time, the length direction of each mounting plate 1 is the same as the radial direction of the first side wall 01, that is, the connection effect between the flushing device and the first side wall 01 is better.

[0032] refer to Figure 4In an exemplary embodiment, the positioning assembly 3 may include two first support portions 31, two first rotating shafts 32 and two positioning wheels 33, wherein the two first support portions 31 are relatively arranged on both sides of the walking wheel 2 in the length direction of the mounting plate 1; the two first rotating shafts 32 correspond one-to-one to the two first support portions 31 and are rotatably connected to the side of the corresponding first support portion 31 away from the mounting plate 1, the axial direction of the first rotating shaft 32 is the same as the thickness direction of the mounting plate 1, and the first rotating shaft 32 has the freedom to rotate around its own axial direction; the two positioning wheels 33 correspond one-to-one to the two first rotating shafts 32 and are sleeved on the outer periphery of the corresponding first rotating shafts 32, and the two positioning wheels 33 respectively contact the inner periphery and the outer periphery of the first side wall 01.

[0033] Specifically, when the flushing device moves along the circumference of the first side wall 01, taking a mounting plate 1 as an example, the two positioning wheels 33 respectively contact the inner periphery and the outer periphery of the first side wall 01, and at the same time, the two positioning wheels 33 rotate around the thickness direction of the mounting plate 1, so that the mounting plate 1 contacts the first side wall 01 through the walking wheel 2 and the two positioning wheels 33. On the premise of maintaining a stable connection between the mounting plate 1 and the first side wall 01, the friction mode between the mounting plate 1 and the first side wall 01 is rolling friction, which effectively reduces the wear caused by the positioning component 3 during operation and increases the service life of the flushing device.

[0034] The greater the difference in distance between the two positioning wheels 33 and the traveling wheel 2 in the gravity direction, the more stable the connection between the corresponding mounting plate 1 and the first side wall 01 .

[0035] refer to Figure 4 In an exemplary embodiment, a slide groove 11 is provided on the side of the mounting plate 1 facing the corresponding walking wheel 2; the flushing device may also include a slider 71, a threaded rod 72 and a knob 73, wherein the slider 71 is slidably matched with the slide groove 11, and the slider 71 has the freedom to slide along the length direction of the mounting plate 1; the threaded rod 72 is axially the same as the length direction of the mounting plate 1 and is rotatably connected in the slide groove 11, the threaded rod 72 has the freedom to rotate around its own axis, and one end of the threaded rod 72 extends out of the mounting plate 1; the knob 73 is fixed to one end of the threaded rod 72 extending out of the mounting plate 1; wherein the slider 71 is fixedly connected to a first support portion 31.

[0036] Specifically, the threaded rod 72 is driven by manually turning the knob 73 to drive the threaded rod 72 to rotate around the axial direction of the threaded rod 72. The threaded rod 72 passes through the slider 71 and is threadedly connected to the slider 71. When the threaded rod 72 rotates, it drives the slider 71 to slide in the slide groove 11 along the length direction of the mounting plate 1. The two first support portions 31 are relatively arranged on both sides of the traveling wheel 2 in the length direction of the corresponding mounting plate 1. The slider 71 is fixed to a first support portion 31. When the knob 73 is turned to drive the slider 71 to slide along the length direction of the mounting plate 1, the slider 71 drives the corresponding first support portion 31 to slide along the length direction of the mounting plate 1. In this way, the distance between the two first support portions 31 can be adjusted, thereby adjusting the distance between the two positioning wheels 33. Further, the mounting plate 1 can be connected to the first side wall 01 of different thicknesses through the two positioning wheels 33 and the traveling wheel 2, so that the flushing device has a wider range of applications.

The transmission shaft 41 passes through the mounting plate 1 and is rotatably connected to the mounting plate 1. The transmission shaft 41 has the freedom to rotate around its own axial direction. The transmission shaft 41 rotates around its own axial direction in response to the driving force; the active bevel wheel 42 is sleeved on the outer periphery of the transmission shaft 41, and the active bevel wheel 42 is located on the side of the mounting plate 1 facing the corresponding walking wheel 2; the driven bevel wheel 43 is sleeved on the outer periphery of the second rotating shaft 82, and the driven bevel wheel 43 is meshed with the active bevel wheel 42; wherein the driving member 5 is arranged on the side of the mounting plate 1 away from the corresponding walking wheel 2, the driving member 5 is connected to the transmission shaft 41, and the driving member 5 provides driving force for the transmission shaft 41.

[0038] Specifically, the driving member 5 can be a motor, which can be connected to an external power supply or to a battery. The battery can be set on the mounting plate 1, and the output shaft of the motor is connected to the transmission shaft 41. When the motor rotates, it drives the transmission shaft 41 to rotate around its own axis, and the transmission shaft 41 drives the active bevel wheel 42 to rotate around its own axis. The active bevel wheel 42 is meshed with the driven bevel wheel 43, and the driven bevel wheel 43 is sleeved on the outer periphery of the second rotating shaft 82. When the active bevel wheel 42 rotates, it drives the driven bevel wheel 43 and the second rotating shaft 82 to rotate around the axial direction of the second rotating shaft 82. The second rotating shaft 82 further drives the walking wheel 2 to rotate. When the walking wheel 2 rotates, it cooperates with the corresponding two positioning wheels 33 to drive the corresponding mounting plate 1 and the remaining mounting plates 1 to move circumferentially along the first side wall 01.

[0039] Among them, on the mounting plate 1 without the transmission assembly 4 , the circumferential movement of the mounting plate 1 along the first side wall 01 drives the running wheel 2 and the second rotating shaft 82 to rotate circumferentially around the second rotating shaft 82 .

[0040] refer to Figure 3 and Figure 4 In an exemplary embodiment, the flushing assembly 6 may include a water pump 61, a water inlet pipe 62, two shunt pipes 63 and a plurality of nozzles 64, wherein the water pump 61 is arranged on the side of the mounting plate 1 away from the corresponding running wheel 2, and the water pump 61 has a water inlet and a water outlet; one end of the water inlet pipe 62 is connected to the water inlet of the water pump 61; the two shunt pipes 63 are arranged in parallel on the side of the mounting plate 1 facing the corresponding running wheel 2 in the length direction of the mounting plate 1, and the two shunt pipes 63 are located at the first Between the side wall 01 and the second side wall 02, the water outlet of the water pump 61 is connected to the two diversion pipes 63 respectively; a plurality of nozzles 64 are arranged at intervals on the outer periphery of the diversion pipe 63 in the axial direction of the diversion pipe 63; wherein, the two diversion pipes 63 are respectively close to the first side wall 01 and the second side wall 02, and the nozzle 64 arranged on the diversion pipe 63 close to the first side wall 01 faces the first side wall 01, and the nozzle 64 arranged on the diversion pipe 63 close to the second side wall 02 faces the second side wall 02.

[0041] Specifically, the water pump 61 sucks water from the water inlet pipe 62 and transports it to the two branch pipes 63, and the water is further sprayed out by multiple nozzles 64 on the two branch pipes 63. The nozzles 64 arranged on the branch pipe 63 close to the first side wall 01 are directed toward the first side wall 01, and the nozzles 64 arranged on the branch pipe 63 close to the second side wall 02 are directed toward the second side wall 02. In this way, the water is sprayed by the nozzles 64 on the two branch pipes 63 to the inner periphery of the first side wall 01 and the outer periphery of the second side wall 02, thereby flushing the first side wall 01 and the second side wall 02 of the water outlet cofferdam.

[0042] Furthermore, the water inlet pipe 62 can be submerged in the water in the outlet cofferdam, so that no additional water source is required when the flushing device is working; of course, the water inlet pipe 62 can also be connected to an external water source.

[0043] refer to Figure 2 and Figure 4 In an exemplary embodiment, a first support portion 31 corresponding to a positioning wheel 33 abutting against an inner periphery of the first side wall 01 is fixed to a slider 71; the flushing assembly 6 may further include a connecting rod 65 and a telescopic rod 66, wherein the connecting rod 65 is fixedly connected to the first support portion 31 fixed to the slider 71, wherein a shunt pipe 63 close to the first side wall 01 passes through the connecting rod 65 and is fixed to the connecting rod 65; the telescopic rod 66 extends along the length direction of the mounting plate 1, and both ends of the telescopic rod 66 are respectively connected to the connecting rod 65 and the shunt pipe 63 close to the second side wall 02, and the telescopic rod 66 has the freedom to extend along the length direction of the mounting plate 1.

[0044] Specifically, when the distance between the corresponding two positioning wheels 33 is adjusted according to the thickness of the first side wall 01, the first support part 31 fixed to the slider 71 moves, which will drive the connecting rod 65 to move synchronously. Then, when the connecting rod 65 moves, it drives the diverter pipe 63 close to the first side wall 01 to move synchronously. In this way, the distance between the diverter pipe 63 close to the first side wall 01 and the first side wall 01 remains unchanged. No matter on which water outlet cofferdam of the second sedimentation tank the flushing device is installed, the nozzle 64 on the diverter pipe 63 close to the first side wall 01 is convenient for flushing the first side wall 01; further, by adjusting the telescopic length of the telescopic rod 66, the distance between the other diverter pipe 63 and the second side wall 02 can be adjusted. No matter on which water outlet cofferdam of the second sedimentation tank the flushing device is installed, the distance between a diverter pipe 63 and the second side wall 02 can be adjusted, so that the nozzle 64 on the corresponding diverter pipe 63 is convenient for flushing the second side wall 02.

[0046] Specifically, the water pump 61 pumps water from the water inlet pipe 62 to the connecting pipe 67 , and the water further flows through the three-way valve 68 to the two hoses 69 and the corresponding diversion pipes 63 .

[0047] Furthermore, when the telescopic rod 66 reaches the maximum stroke, the hose 69 is in a relaxed state. In this way, no matter to what length the telescopic rod 66 is extended, water can still be transported to the diversion pipe 63, and the hose 69 will not affect the extension and retraction process of the telescopic rod 66.

[0048] refer to Figure 3 In an exemplary embodiment, the flushing device may further include a counterweight 12, which is fixed to the side of the mounting plate 1 facing the water pump 61. At this time, the weight of the mounting plate 1 on both sides of the first side wall 01 is not much different, which effectively prevents the mounting plate 1 from tipping over because most of the components of the flushing assembly 6 are located between the first side wall 01 and the second side wall 02.

[0049] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
