Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Example 1: A negative pressure sewage collection system, such as Figures 1-6 As shown, it includes a gravity collection cylinder 2, a collection system, a vacuum pipeline system, and a processing system.

[0031] The collection system includes a receiving riser 1, which is used for gravity flow guidance support of sewage.

[0032] The vacuum pipeline system includes a vacuum valve well 3, a vacuum branch pipe 4, a vacuum main pipe 5, and a vacuum pump station 6. The vacuum valve well 3 is connected to the vacuum main pipe 5 through the vacuum branch pipe 4. Several vacuum branch pipes 4 are connected to the vacuum main pipe 5. The vacuum pump station 6 is located outside the vacuum main pipe 5.

[0033] Vacuum pump station 6 also constitutes a separate processing system.

[0034] An automatic discharge system is installed between the collection system and the vacuum pipeline system, and the automatic discharge system is located inside the gravity collection cylinder 2.

[0035] The specific operating procedure of the device is as follows: First, the device is installed in shallow underground to avoid engineering problems, effectively preventing issues such as deep digging, road breaking, interference with pipeline distribution, and groundwater. Second, the collection system is installed at each sewage discharge point. Under its own gravity, the wastewater flows a short distance and continuously flows into the gravity collection cylinder 2 through the receiving riser 1. When the liquid level reaches the set value, the automatic discharge system inside the gravity collection cylinder 2 transmits an operation signal to the vacuum pipeline system. Then, the vacuum pipeline system automatically starts, drawing the wastewater into the vacuum pipeline system, which then flows through the vacuum valve well 3, vacuum branch pipe 4, and vacuum main pipe 5 to the vacuum pump station 6. Finally, the wastewater is processed in the treatment system. This allows the device to have a multi-point collection and automatic suction negative pressure treatment mode. Furthermore, with the support of the powerful vacuum pipeline system, sewage blockage and siltation are effectively avoided, improving the efficiency of sewage treatment.

[0036] like Figures 1-6As shown, a water pump and a control terminal are installed inside the vacuum valve well 3, and a control terminal is installed inside the vacuum pump station 6. The control terminal is used to receive signals sent by the automatic discharge system and control the operation of the water pump. The well port of the vacuum valve well 3 is sealed to the water pump suction port.

[0037] The gravity collection cylinder 2 is connected to the vacuum valve well 3 through a pipe, and the main vacuum pipe 5 is connected to the vacuum pump station 6 through the vacuum branch pipe 4.

[0038] With the separate or simultaneous operation of water pumps inside multiple vacuum valve wells 3, and with the connection and support between vacuum branch pipes 4 and external pipes, the power for sewage suction at each discharge point is stable and the sewage flow is smooth, thus ensuring continuous and efficient overall pumping power of the device. Furthermore, with the signal transmission connection between the control terminal in the vacuum valve wells 3 and the vacuum pump station 6 and the automatic discharge system, the control process can be processed accurately and quickly, improving the accuracy of its automatic operation and further enhancing the efficiency of the device in sewage treatment.

[0039] like Figures 1-6 As shown, the automatic discharge system includes an isolation shell 7 for water-proof protection support, a floating support block 14 for movable support, an operation signal transmitter 12 for switching signal transmission, and a shutdown signal transmitter 19. The upper end of the floating support block 14 is threadedly connected to an adjustment rod 13, and the upper end of the adjustment rod 13 is threadedly connected to an adjustment U-shaped tube 10. The end of the adjustment U-shaped tube 10 away from the adjustment rod 13 is threadedly connected to an adjustment guide rod 9. The adjustment guide rod 9 and the adjustment rod 13 are slidably disposed on both sides inside the isolation shell 7. A pressing block 11 for pressing the operation signal transmitter 12 is installed in the middle of the upper half of the adjustment U-shaped tube 10, and a pressing plate 18 for pressing the shutdown signal transmitter 19 is provided below the adjustment guide rod 9.

[0040] The automatic emission system also includes a movable frame 8 for guidance and support, a sliding assembly 15, an outer guide rail 16 for guidance assistance, and an inner guide groove 17. The outer guide rail 16 is disposed through the upper and lower ends of the outer side of the isolation shell 7. The two inner guide grooves 17 are symmetrically opened on the inner wall of the isolation shell 7. The rollers on the sliding assembly 15 are slidably disposed inside the outer guide rail 16. The guide plates on opposite sides of the movable frame 8 are slidably disposed inside the inner guide grooves 17. The pressing plate 18 is installed on the lower half of the outer side of the movable frame 8.

[0041] The movable frame 8 is threadedly connected to the adjusting guide rod 9, the floating support block 14 is fixedly connected to the sliding assembly 15, and a rotating ring is provided in the middle of the adjusting rod 13. The upper and lower ends of the rotating ring are rotatably connected to the upper and lower parts of the adjusting rod 13, respectively.

[0042] Based on the buoyancy support of the outer buoyancy ring of the floating support block 14, when the liquid level rises, the buoyancy generated causes the floating support block 14 to move upward. This, connected by the adjusting U-shaped tube 10, drives the adjusting rods 13 on both sides and the adjusting guide rod 9 to move synchronously. This causes the pressing block 11 to move towards the operation signal transmitter 12 and press it, sending signals to the two control terminals to control the water pump and vacuum pump station 6 to operate and pump. When the liquid level continues to drop, under the weight of the device itself, the pressing plate 18 moves towards the shut-off signal transmitter 19, making the pressing plate 18 contact and press the shut-off signal transmitter 19, sending signals to the control terminals. This causes the control terminals to stop the operation of the water pump and vacuum pump station 6, and the operation and shutdown settings of the vacuum pump station 6 are set later than those of the water pump to ensure stable sewage extraction. At the same time, the combined use of multiple sets of guiding components ensures the accuracy of the device's floating movement and automatic reset.

[0043] like Figures 1-6 As shown, two symmetrically distributed L-shaped support frames 21 are installed on the upper half of the inner wall of the isolation shell 7. The horizontal part of the L-shaped support frame 21 is a connecting plate, and the vertical part of the L-shaped support frame 21 is a connecting cylinder. A guide groove is provided on the side of the connecting cylinder. A reset spring 23 is installed inside the connecting cylinder, and a reset connecting frame 20 is provided below the reset spring 23.

[0044] At least two limiting components 22 are installed on the upper end of the reset connecting frame 20. The limiting components 22 themselves are symmetrical structures. The middle part of the limiting components 22 is a guide shaft. The guide shaft has symmetrically distributed limiting disks at both ends below. A guide block is installed on the outer side of the upper guide disk. The guide shaft extends into the inside of the connecting cylinder. The upper limiting disk is fixedly connected to the reset spring 23. The guide block is slidably disposed in the guide groove. The lower limiting disk is installed on the upper surface of the reset connecting frame 20.

[0045] When the movable frame 8 is supported by the buoyancy force on one side and continues to move upward, when the movable frame 8 contacts the reset connecting frame 20, the volume of sewage is relatively large. The buoyancy generated drives the reset connecting frame 20 and the limiting component 22 to move towards the L-shaped support frame 21, causing the reset spring 23 to continuously contract. When the sewage is sucked in, the buoyancy gradually decreases. Based on the elastic support of the reset spring 23 itself, it pushes the movable frame 8 to reset and provides it with the power to move downward, thereby providing a limit for the upward movement of the movable frame 8 and providing power support for the reset of the movable frame 8, further improving the efficiency and accuracy of the device.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
