Description

Technical Field

[0001] This invention relates to the field of prefabricated pumping station technology, specifically a prefabricated pumping station with self-cleaning function. Background Technology

[0002] Prefabricated pumping stations are integrated products that combine submersible pumps, pumping station equipment, sludge removal screens, control systems, and remote monitoring systems. Prefabricated pumping stations are characterized by their mobility, extremely short construction period, and ease of installation, making them a new trend in pumping station construction in China's municipal industry. However, in practice, we have found that existing prefabricated pumping stations accumulate large amounts of sludge after long-term use. If this sludge is not cleaned in time, it will affect the normal operation of the pumping station. Furthermore, manually entering the prefabricated pumping station to clean the sludge can lead to poisoning of workers due to toxic gases produced by sludge fermentation. Therefore, we propose a prefabricated pumping station with self-cleaning capabilities. Summary of the Invention

[0008] An auxiliary component is used to assist the ventilation components in stirring and cleaning the sewage inside the pump station body. The auxiliary component is installed inside the pump station body.

[0009] Further optimization measures for this technical solution are as follows:

As the blower pump draws in air, the transmission rod at its output end drives the first bevel gear to rotate. The second bevel gear, under the action of the first bevel gear, drives the rotating rod below it to rotate. This, in turn, causes the rotating rod to drive the brush at the bottom of the rotating rod to rotate, allowing the brush to scrub the water collection tank, thereby removing the sludge adhering to the sides and bottom of the water collection tank.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Please see Figures 1-9 The present invention provides a technical solution: a prefabricated pumping station with self-cleaning function, comprising a pumping station body 1 and a water collection tank 2 formed at the bottom of the pumping station body 1, and further comprising...

[0035] The brush 3 is used to scrub the sludge attached to the water collection tank 2. Multiple brushes 3 are provided, and the multiple brushes 3 are equally spaced above the water collection tank 2.

[0036] Ventilation component 4 is used to prevent sewage from settling inside the pump station body 1. Ventilation component 4 is installed inside the pump station body 1.

[0037] The scrubbing component 5 is used to scrub away the silt adhering to the water collection tank 2. The scrubbing component 5 is installed inside the water collection tank 2.

[0038] Auxiliary component 6 is used to assist the ventilation component 4 in stirring and cleaning the sewage inside the pump station body 1. Auxiliary component 6 is installed inside the pump station body 1.

[0039] The ventilation component 4 includes a blower pump 41 installed inside the pump station body 1. The blower pump 41 has an air inlet pipe 42 and an air outlet pipe 43. The end of the air inlet pipe 42 away from the blower pump 41 is located at the top of the pump station body 1, and the end of the air outlet pipe 43 away from the blower pump 41 is located inside the pump station body 1. When water begins to enter the pump station body 1, the blower pump 41 is turned on. The blower pump 41 will draw air from outside the pump station body 1 into the pump station body 1 through the air inlet pipe 42 and the air outlet pipe 43. The function of the blower pump 41 inflating the pump station body 1 is to prevent sewage from settling and to accelerate the discharge of toxic gases generated by sludge inside the pump station body 1.

[0040] The brushing assembly 5 includes a transmission component 7 installed at the output end of the blower pump 41 for transmission, a fixing component 8 installed above the water collection tank 2 for fixing the positions of multiple brushes 3, and a synchronizing component 9 installed between the multiple brushes 3 and the fixing component 8 for synchronously controlling the rotation of the multiple brushes 3.

[0041] The transmission component 7 includes a transmission rod 71 disposed at the output end of the blower pump 41. A first bevel gear 72 is disposed on the outer side of the transmission rod 71. When the blower pump 41 starts to work, the transmission rod 71 disposed at its output end will start to rotate under the action of the blower pump 41. When the transmission rod 71 rotates, the transmission rod 71 will drive the first bevel gear 72 disposed at the end away from the blower pump 41 to rotate. The function of the first bevel gear 72 is to transmit power to the second bevel gear 84, so that the brush 3 can work normally.

[0042] The fixing component 8 includes multiple fixing rods 81 equidistantly arranged above the water collection tank 2. Each fixing rod 81 is equipped with a bearing 82, and each bearing 82 contains a rotating rod 83. The bottom of each rotating rod 83 is located on the top of an adjacent brush 3. A second bevel gear 84 is located on the top of one rotating rod 83 near the first bevel gear 72, and the first bevel gear 72 meshes with the second bevel gear 84. When the first bevel gear 72 rotates, the second bevel gear 84 meshing with the first bevel gear 72 will rotate under the action of the first bevel gear 72, thereby causing the second bevel gear 84 to drive the rotating rod 83 to rotate in the bearing 82 on the fixing rod 81. When the rotating rod 83 starts to rotate, the brush 3 located at the bottom of the rotating rod 83 will rotate with the rotating rod 83, thereby causing the brush 3 to brush the sides and bottom of the water collection tank 2. The function of the fixing rod 81 is to position the height of the rotating rod 83, so that the brush 3 at the bottom of the rotating rod 83 is at the normal working height.

[0043] The synchronizing element 9 includes synchronizing gears 91 respectively disposed at the bottom of multiple rotating rods 83. A synchronizing belt 92 is disposed on the outer side of the multiple synchronizing gears 91, and multiple locking teeth 93 meshing with the multiple synchronizing gears 91 are disposed inside the synchronizing belt 92. Two pressing elements 94 are disposed at the bottom of each fixed rod 81 located in the middle. Each pressing element 94 includes two auxiliary rods 941 disposed at the bottom of the fixed rod 81. Auxiliary wheels 942 are rotatably disposed at both ends of each auxiliary rod 941 via a rotating shaft, and the four auxiliary wheels 942 are respectively disposed on both sides of the transmission belt. When the rotating rod 83 rotates, the synchronizing gears 91 disposed on the outer side of the rotating rod 83 will rotate together with the rotating rod 83. When the synchronizing gears 91 rotate, they will... Under the action of multiple teeth 93 set on the synchronous belt 92, multiple synchronous gears 91 are driven to rotate together, so that multiple brushes 3 brush the sides and bottom of the water collection tank 2. When the synchronous belt 92 moves, the auxiliary rod 941 set on the fixed rod 81 will squeeze the outside of the synchronous belt 92 by rotating the auxiliary wheels 942 set at both ends of the auxiliary rod 941, thereby preventing the synchronous gear 91 in the middle from being unable to mesh with the multiple teeth 93 when the synchronous gear 91 rotates. The function of the auxiliary rod 941 is to control the auxiliary wheels 942 set at both ends of it to squeeze the synchronous belt 92, ensuring that the multiple teeth 93 on the synchronous belt 92 can drive the multiple synchronous gears 91 to rotate synchronously.

[0044] The auxiliary component 6 includes a stirring element 10 installed inside the pump station body 1 for stirring sewage, and a water storage element 11 installed inside the pump station body 1 for storing clean water.

[0045] The mixing component 10 includes a waterproof cover 101 disposed on one side of the blower pump 41. A mixing motor 102 is disposed inside the waterproof cover 101. A mixing rod 103 is disposed at the output end of the mixing motor 102. A mixing blade 104 is disposed at the end of the mixing rod 103 away from the mixing motor 102. When the sewage entering the pump station body 1 exceeds the height of the mixing blade 104, the mixing motor 102 is turned on. The mixing motor 102 drives the mixing rod 103 to rotate, thereby causing the mixing rod 103 to drive the mixing blade 104 disposed at one end to rotate. When the mixing blade 104 rotates, the mixing blade 104 will agitate the sewage, keeping the water flow active and preventing sewage sedimentation, which would cause a large amount of sludge to adhere to the inner wall of the pump station body 1. The function of the waterproof cover 101 is to prevent water from entering the mixing motor 102 and causing damage to the mixing motor 102.

[0046] The water storage unit 11 includes a water storage tank 111 located on the side of the blower pump 41 away from the stirring motor 102. A water storage chamber 112 is provided inside the water storage tank 111. A water outlet pipe 113 is located on the side of the water storage tank 111 closest to the water collection tank 2. A solenoid valve 115 is installed at the top of the water outlet pipe. A water filling pipe 114 is installed at the top of the water storage tank 111, with one end of the water filling pipe 114 away from the water storage tank 111 located at the top of the pump station body 1. The water storage chamber 112 inside the water storage tank 111 can hold a large volume of water. After the sewage in the pump station body 1 is pumped out, the water storage tank 112 is opened by the solenoid valve 115, so that the clean water in the water storage tank 112 flows into the pump station body 1 through the water outlet pipe 113, so that the clean water cleans the pump station body 1 again. When there is not enough clean water in the water storage tank 112, clean water can be injected through the water filling pipe 114. The function of the water storage tank 112 is to store enough clean water, so as to reduce the sludge in the pump station body 1 through the flushing of clean water.

[0047] During operation, when water begins to enter the pump station body 1, the blower pump 41 is turned on. The blower pump 41 draws air from outside the pump station body 1 into the pump station body 1 through the air inlet pipe 42 and the exhaust pipe 43. When the blower pump 41 starts working, the transmission rod 71 at its output end will start to rotate under the action of the blower pump 41. When the transmission rod 71 rotates, it will drive the first bevel gear 72 located at the end away from the blower pump 41 to rotate. When the first bevel gear 72 rotates, the second bevel gear 84 meshing with the first bevel gear 72 will rotate under the action of the first bevel gear 72, thereby... The second bevel gear 84 drives the rotating rod 83 to rotate within the bearing 82 on the fixed rod 81. When the rotating rod 83 starts to rotate, the brush 3 located at the bottom of the rotating rod 83 rotates along with it, thus allowing the brush 3 to scrub the sides and bottom of the water collection tank 2. As the rotating rod 83 rotates, the synchronizing gear 91 located on the outside of the rotating rod 83 also rotates along with it. When the synchronizing gear 91 rotates, it is driven by multiple locking teeth 93 located on the synchronizing belt 92, causing multiple synchronizing gears 91 to rotate together, thus allowing multiple brushes 3 to scrub the water collection tank 2. The sides and bottom are brushed. When the synchronous belt 92 moves, the auxiliary rod 941 set on the fixed rod 81 will squeeze the outside of the synchronous belt 92 by rotating the auxiliary wheels 942 set at both ends of the auxiliary rod 941, thereby preventing the synchronous gear 91 located in the middle from being unable to mesh with the multiple locking teeth 93 when the synchronous gear 91 rotates. When the sewage entering the pump station body 1 exceeds the height of the stirring fan blade 104, the stirring motor 102 is turned on. The stirring motor 102 will drive the stirring rod 103 to rotate, thereby causing the stirring rod 103 to drive the stirring fan blade 104 set at one end to rotate. When the stirring fan... When the blade 104 rotates, the stirring blade 104 will drive the sewage to move, so that the water flow is active and the sewage will not settle, causing a large amount of sludge to adhere to the inner wall of the pump station body 1. The water storage tank 112 opened in the water storage tank 111 can store a large amount of clean water. When the sewage in the pump station body 1 is pumped out, the water storage tank 112 is opened by the solenoid valve 115, so that the clean water in the water storage tank 112 flows into the pump station body 1 through the water outlet pipe 113, so that the clean water cleans the pump station body 1 again. When there is not enough clean water in the water storage tank 112, clean water can be injected through the water filling pipe 114.

[0048] Example 2

[0049] Please see Figures 1-10 The present invention provides a technical solution: Unlike embodiment 1, a filter plate 12 is provided at the end of the exhaust pipe 43 away from the blower pump 41. When the water level in the pump station body 1 is lower than the height of the exhaust pipe 43, the filter plate 12 can isolate branches, fallen leaves or other large-volume garbage that may exist in the sewage, so as to avoid damage to the blower pump 41.
