Description

Technical Field

[0001] This utility model relates to the field of regulating reservoir technology, and in particular to a vacuum chamber structure for dredging regulating reservoirs. Background Art

[0002] When cities experience rainfall, runoff often increases, and rainwater and sewage frequently converge, increasing the burden on urban drainage and sewage networks. This is especially true in the early stages of rainfall, when the initial rainwater contains a large amount of pollutants. If this initial rainwater is directly discharged into natural water bodies, it will cause serious pollution to the aquatic environment. Storage tanks are a common feature in municipal water system planning, playing an indispensable role in regulating urban drainage, rainwater, and wastewater. Vacuum chamber structures utilize vacuum technology to remove silt and impurities from the storage tank through suction, achieving a rapid, efficient, and environmentally friendly dredging effect.

[0003] A search revealed an intelligent vacuum cleaning system disclosed in publication number CN212772757U, comprising a water storage chamber, a storage tank, and a collection tank connected in sequence. A gap is provided at the bottom of the side wall between the water storage chamber and the storage tank, and a protrusion is fixedly installed at the bottom of the storage tank adjacent to the water storage chamber. The gap of the protrusion fits together to form a siphon unit. A vacuum valve is installed on the top of the water storage chamber. The bottom of the collection tank is lower than the bottom of the storage tank. A control cabinet is fixedly installed above the water storage chamber, and a vacuum pump is fixedly installed inside the control cabinet. The vacuum valve is connected to the sealing pipe of the vacuum pump. This utility model overcomes the shortcomings of the prior art. It effectively prevents impurities from entering the water storage chamber through the protrusion and the guide wall. The upper part of the first regulating tank is a closed structure, which blocks the sludge from flowing directly into the siphon unit and then into the water storage chamber, further ensuring the cleanliness of the water storage chamber. The bottom of the regulating tank is cleaned by vacuum suction in combination with the siphon principle. In this application, the vacuum chamber structure cleans the sludge at the bottom of the regulating tank through the siphon unit, but the sludge is not centrally treated. When rinsing the sludge, the sludge will mix with the water and then be discharged. Although the sludge at the bottom of the regulating tank is cleaned, the direct discharge of the sludge can easily cause environmental pollution. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a vacuum chamber structure for dredging storage tanks. The aim is to improve the vacuum chamber structure by using a siphon unit to clean the sludge at the bottom of the storage tank. However, the sludge is not centrally treated, and direct discharge of sludge can easily cause environmental pollution.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum chamber structure for dredging a water storage tank, comprising a water storage tank, a filter screen slidably connected inside the water storage tank, a collection box fixedly connected to the lower end of the outer wall of the water storage tank, a support fixedly connected to the upper surface of the collection box, a vacuum pump fixedly connected to the upper surface of the support, an air extraction pipe fixedly connected to the input end of the vacuum pump, the outer wall of the air extraction pipe fixedly connected to the inside of the collection box, a storage box slidably connected to the inner wall of the collection box, a handle fixedly connected to the outer wall of the storage box, a sealing ring fixedly connected to the outer wall of the storage box, multiple extraction pipes fixedly connected inside the collection box, the outer wall of the extraction pipe penetrating and disposed inside the storage box, the outer wall of the extraction pipe disposed inside the water storage tank, a connecting pipe fixedly connected to the outer wall of the extraction pipe, multiple suction nozzles fixedly connected to the top end of the connecting pipe, and a water inlet assembly disposed on the outer wall of the water storage tank.

[0006] Furthermore, the water inlet assembly includes a grinding chamber, with a water inlet pipe fixedly connected to the top of the grinding chamber and a water outlet pipe fixedly connected to the bottom of the grinding chamber. The outer wall of the water outlet pipe is fixedly connected to the interior of the water storage tank, and the outer wall of the grinding chamber is fixedly connected to the interior of the water storage tank.

[0007] Furthermore, a motor is fixedly connected to the outer wall of the crushing box, and a crushing roller is fixedly connected to the output end of the motor.

[0008] Furthermore, a gear is fixedly connected to the outer wall of the first crushing roller, and a second crushing roller is rotatably connected inside the crushing box. A gear is fixedly connected to the outer wall of the second crushing roller, and the first gear and the second gear mesh with each other.

[0009] Furthermore, a filter box is fixedly connected to the lower end of the outer wall of the water storage tank, and a filter plate is fixedly connected inside the filter box.

[0010] Furthermore, a water pump is fixedly connected to one side of the filter box, a water pumping pipe is fixedly connected to the input end of the water pump, a delivery pipe is fixedly connected to the output end of the water pump, and the outer wall of the delivery pipe is fixedly connected to the inside of the filter box.

[0011] Furthermore, the outer wall of the pumping pipe is located inside the water storage tank, and multiple suction nozzles are fixedly connected to the top end of the pumping pipe.

[0012] Furthermore, a drain pipe is fixedly connected inside the filter box, and a solenoid valve is installed inside the drain pipe.

[0013] The utility model has the following beneficial effects:

[0014] In this invention, the air inside the collection box is first drawn out by activating a vacuum pump, reducing the pressure inside the collection box. Then, through the cooperation of the extraction pipe, connecting pipe, and suction nozzle, the sludge inside the reservoir is quickly extracted. By pulling the handle, the sealing ring and storage box are moved out of the collection box, achieving the effect of quickly processing the collected sludge. This solves the problem that the direct discharge of sludge from the bottom of the storage tank using a siphon unit in a vacuum chamber structure can easily cause environmental pollution, thus improving the efficiency of the vacuum chamber structure in quickly processing sludge.

[0015] In this invention, rainwater is drained into the pulverizing chamber through the water inlet pipe. The motor is started to rotate the first pulverizing roller. Through the cooperation of the first pulverizing roller, the first gear, and the second gear bracket, the second pulverizing roller rotates in the opposite direction to the first pulverizing roller. This achieves the effect of fully pulverizing larger impurities such as stones and branches inside the rainwater, preventing the pipe from being blocked when transporting rainwater, and improving the practicality of the vacuum chamber structure.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1-3 This utility model provides an embodiment of a vacuum chamber structure for dredging a water storage tank, comprising a water storage tank 1, a filter screen 22 slidably connected inside the water storage tank 1, a collection box 2 fixedly connected to the lower end of the outer wall of the water storage tank 1, a support 3 fixedly connected to the upper surface of the collection box 2, a vacuum pump 4 fixedly connected to the upper surface of the support 3, an air extraction pipe 5 fixedly connected to the input end of the vacuum pump 4, the outer wall of the air extraction pipe 5 fixedly connected to the inside of the collection box 2, a storage box 6 slidably connected to the inner wall of the collection box 2, a handle 7 fixedly connected to the outer wall of the storage box 6, a sealing ring 8 fixedly connected to the outer wall of the storage box 6, multiple extraction pipes 9 fixedly connected inside the collection box 2, the outer wall of the extraction pipes 9 penetrating and disposed inside the storage box 6, the outer wall of the extraction pipes 9 disposed inside the water storage tank 1, a connecting pipe 10 fixedly connected to the outer wall of the extraction pipes 9, multiple suction nozzles 11 fixedly connected to the top end of the connecting pipe 10, and a water inlet assembly disposed on the outer wall of the water storage tank 1.

[0025] Specifically, the filter screen 22 inside the water storage tank 1 filters the silt inside the rainwater. This filter screen 22 can effectively remove impurities and silt from the water, ensuring the cleanliness and smooth flow of rainwater. When the filter screen 22 needs cleaning, the vacuum pump 4 on the upper surface of the bracket 3 is activated. The vacuum pump 4 quickly removes the air inside the collection box 2 through the air extraction pipe 5, creating a vacuum environment inside the collection box 2. This environment can generate a strong suction force, which helps the extraction pipe 9 to extract the air inside the connecting pipe 10. In the vacuum environment, the suction nozzle 11 generates suction force due to the decrease in pressure. This suction force can quickly suck the silt on the surface of the filter screen 22 into the inside of the collection box 2.

[0026] Reference Figure 4 The water inlet assembly includes a grinding box 12, with a water inlet pipe 13 fixedly connected to the top of the grinding box 12 and a water outlet pipe 14 fixedly connected to the bottom of the grinding box 12. The outer wall of the water outlet pipe 14 is fixedly connected to the inside of the water storage tank 1. The outer wall of the grinding box 12 is fixedly connected to the inside of the water storage tank 1. A motor 15 is fixedly connected to the outer wall of the grinding box 12. A first grinding roller 16 is fixedly connected to the output end of the motor 15. A first gear 17 is fixedly connected to the outer wall of the first grinding roller 16. A second grinding roller 19 is rotatably connected inside the grinding box 12. A second gear 18 is fixedly connected to the outer wall of the second grinding roller 19. The first gear 17 and the second gear 18 mesh with each other.

[0027] Specifically, collected rainwater is introduced into the pulverizing chamber 12 through the inlet pipe 13. The rainwater flows into the pulverizing chamber 12 through the pipe, preparing for the subsequent pulverizing process. Next, the motor 15 is started to drive the pulverizing roller 16 to rotate. The pulverizing roller 16 is connected to the gear 17, so its rotation also drives the rotation of the gear 17. The gear 17 is connected to the meshing gear 18, so the rotation of the gear 17 also drives the rotation of the gear 18. The rotation of the gear 18, in turn, drives the rotation of the pulverizing roller 19. Through the cooperation between the pulverizing roller 16 and the pulverizing roller 19, they jointly complete the pulverizing effect of the rainwater. This cooperation ensures that larger debris is pulverized into smaller particles by the interaction of the two pulverizing rollers, thereby preventing debris from clogging the pipe.

[0028] Reference Figure 5 A filter box 20 is fixedly connected to the lower end of the outer wall of the water storage tank 1. A filter plate 26 is fixedly connected inside the filter box 20. A water pump 21 is fixedly connected to one side of the filter box 20. A water pump pipe 23 is fixedly connected to the input end of the water pump 21. A delivery pipe 25 is fixedly connected to the output end of the water pump 21. The outer wall of the delivery pipe 25 is fixedly connected to the inside of the filter box 20. The outer wall of the water pump pipe 23 is located inside the water storage tank 1. Multiple suction nozzles 24 are fixedly connected to the top end of the water pump pipe 23. A drain pipe 27 is fixedly connected inside the filter box 20. A solenoid valve 28 is installed inside the drain pipe 27.

[0029] Specifically, after the water pump 21 is started, the rainwater filtered by the filter screen 22 is drawn through the water pumping pipe 23 and the suction nozzle 24. This rainwater is transported to the delivery pipe 25 and then discharged into the filter box 20. Inside the filter box 20, the rainwater is filtered again through the filter plate 26 to ensure that the water quality is purer. Finally, the solenoid valve 28 connected to the drain pipe 27 is opened, and the filtered rainwater is discharged through the drain pipe 27. This process ensures the effective use of rainwater and also guarantees the safety and purity of the water quality.

[0030] Working Principle: When the device is needed, the collected rainwater is first discharged into the pulverizing tank 12 through the inlet pipe 13. The motor 15 is started, which drives the pulverizing roller 16 to rotate. The pulverizing roller 16 drives the gear 17 to rotate, which in turn drives the meshing gear 18 to rotate. The gear 18 then drives the pulverizing roller 19 to rotate. Through the cooperation between the pulverizing roller 16 and the pulverizing roller 19, larger debris inside the rainwater is pulverized, preventing large debris from clogging the pipes and affecting the use of the water storage tank 1. The filter screen 22 inside the water storage tank 1 filters the silt inside the rainwater. Then, the vacuum pump 4 on the upper surface of the bracket 3 is started, and the air inside the collection tank 2 is quickly pumped out through the air extraction pipe 5. The air is drawn away, creating a vacuum environment inside the collection box 2. Then, the air inside the connecting pipe 10 is drawn out through the extraction pipe 9, causing the suction nozzle 11 to generate suction due to the reduced pressure. This quickly draws the sludge on the surface of the filter screen 22 into the collection box 2. By pulling the handle 7, the storage box 6 is moved out of the collection box 2, facilitating the cleaning of the sludge inside the storage box 6. Next, the water pump 21 is started to draw out the rainwater filtered by the filter screen 22 through the water extraction pipe 23 and the suction nozzle 24. The rainwater is then discharged into the filter box 20 through the delivery pipe 25, where it is filtered again by the filter plate 26 inside the filter box 20. Finally, the filtered rainwater is discharged through the drain pipe 27 by opening the solenoid valve 28 connected to the drain pipe 27.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
