Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology in the environmental protection field, specifically a tubular automatic flushing door device. Background Technology

[0002] In existing technologies, the mainstream cleaning methods for urban pipeline networks include: physical pulse cleaning, high-pressure cleaning trucks, mechanical cleaning, and well-washing fluid cleaning. For example, the "Method and System for Removing Scale from Pipes" disclosed in Publication (Announcement) No. CN107931265A uses a pulsed water flow to flush the pipe to be cleaned, performing pulsed flushing and cleaning of the inner wall of the pipe. This method uses physical pulses to clean the pipe. However, the main disadvantages of existing physical pulse cleaning and high-pressure cleaning vehicles are: high initial investment, high requirements for the experience and professional level of operators, long pipe distances requiring segmented flushing, and the possibility of cracking or deformation of old pipes when flushed.

[0003] For example, the "An Angle-Adjustable Pipe Inner Wall Cleaning Device for Machining" disclosed in Publication No. CN111842364A allows users to rotate the cleaning mechanism, thus enabling omnidirectional adjustment of its angle. Through the coordination of a third motor, water tank, water pump, tee pipe, spray head, housing, spring, telescopic column, and brush, users can easily use the brush to perform omnidirectional rotating cleaning of the pipe's inner wall. This technical solution achieves pipe cleaning through mechanical cleaning; however, the main disadvantages of mechanical cleaning are: low cleaning efficiency, the need for personnel to enter the pipe in some scenarios posing safety hazards, and the need to shut off the flow in the pipe.

[0004] For example, the "Dual-Liquid Well Cleaning Machine with Air Flotation Separation Device" disclosed in Publication No. CN103894363A uses a bubble generating pipe connected to an air compressor. Air passes through small holes in the bubble generating pipe to form tiny bubbles that enter the alkaline water in the alkaline water tank, improving the oil-water separation rate and accelerating the separation time, thus significantly improving the cleaning effect and operating efficiency of the oil cleaning machine. However, cleaning with well cleaning fluid may cause risks such as pipeline corrosion and secondary pollution, and the cost of waste liquid treatment is high, making it not worthwhile.

[0005] Furthermore, all existing cleaning methods suffer from excessive investment, high costs, and the risk of damaging pipes during flushing. In addition, existing technologies pose safety hazards to operators, as well as low cleaning efficiency and environmental pollution.

[0006] Therefore, in order to solve the above problems, it is necessary to develop a tubular automatic flushing door device with a reasonable and stable structure that can effectively improve flushing efficiency and quality. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing a tubular automatic flushing door device; its technical solution is as follows: An automatic flushing gate device includes a water storage well with a pipe installed at the bottom; and a flushing gate seat is also installed at the bottom of the water storage well. A flushing gate plate is embedded in the flushing gate seat, and the position of the flushing gate plate corresponds to the position of the pipe opening. The pipe is placed horizontally, and the flushing gate plate is placed vertically and correspondingly blocks the pipe opening. The upper end of the flushing door panel is also connected to a large lifting buoy, and a small opening and closing buoy is correspondingly installed above the large lifting buoy. A connecting rod is installed at the lower end of the small opening and closing buoy, and a locking mechanism is installed at the end of the connecting rod after it extends vertically downward. The locking mechanism is connected to the large lifting buoy. Under the action of gravity, the small buoy locks the large buoy through a locking mechanism. When the small buoy rises under the action of buoyancy, the locking mechanism unlocks and lifts the large buoy. Lifting the large buoy causes the opening and closing flushing gate to rise, thereby opening the pipe opening.

[0008] Furthermore, tracks are provided on both sides of the flushing door seat, and the flushing door panel is embedded in the tracks on both sides, so that the flushing door panel can move up and down within the tracks on both sides.

[0009] Furthermore, bullseye bearings are installed on both sides of the flushing gate panel, which are embedded in the tracks on both sides of the flushing gate panel; and when the flushing gate panel rises with the lifting pontoon, a buffer pad is installed at the upper end of the track, which limits the rising distance of the flushing gate panel when the flushing gate panel rises with the lifting pontoon.

[0010] Furthermore, several upper and lower supports are installed on the inner wall of the water storage well. The connecting rod at the bottom of the opening and closing small buoy passes through the supports, and the positions of the opening and closing small buoy and the connecting rod are fixed by the supports; and the length of the connecting rod is adjustable.

[0011] Furthermore, the tracks on both sides of the flushing gate extend upwards, and the lifting pontoons are correspondingly installed within the tracks on both sides; the flushing gate plate is connected to the lifting pontoons via connecting plates.

[0012] Furthermore, the locking mechanism is in the shape of a "W", including two inner hinge plates and two outer locking plates. Hinges are installed at the joints between the locking plates and the hinge plates, and hinges are also installed between the two hinge plates. The connecting rod is installed downwards on the hinges between the two hinge plates. The ends of the two locking plates are also provided with locking hooks, and locking plates are correspondingly installed on both sides of the lifting float. The upper ends of the locking plates on both sides are hinged to the tracks on both sides of the flushing gate seat by pins, so that the locking plates on both sides can rotate around the position of the pins. The locking hooks are correspondingly engaged with the locking plates to fix the lifting float. When the locking hooks are flipped outward, the locking plates are unrestricted and the lifting float rises upward.

[0013] Furthermore, the lower end of the locking plate is configured as an inwardly and downwardly extending inclined structure; and the latch hook is provided with a corresponding inclined structure.

[0014] Beneficial effects: This utility model has the following beneficial effects: 1) This device can achieve pipeline flushing by opening and closing the small pontoon and raising the large pontoon. The structure is reasonable and the overall structure is easy to use. It can effectively reduce the initial investment cost and can complete the adaptive flushing work. Only water injection is required. There is no need for personnel to enter the pipeline or water storage well, which effectively reduces the safety hazards of personnel operation and improves work efficiency. 2) In the technical solution of this device, the pipeline cleaning can be automatically started when the water in the water storage well exceeds the opening and closing small float. The pipeline is flushed only by the water pressure in the water storage well, which can effectively reduce the risk of damage to the pipeline during flushing. 3) The technical solution in this device is to open and close the lifting pontoon by opening and closing the small pontoon, and to achieve linkage opening through the locking mechanism set in the middle. The structure is ingenious and reasonable, and is very convenient to use and operate. 4) The locking mechanism in this device has a reasonable structure, consisting of two inner hinge plates and two outer locking plates. It is linked to the opening and closing float via a connecting rod and is locked by the locking plates and locking hooks. The structure is reasonable. 5) The structure of the flushing gate seat, flushing gate plate and lifting pontoon in this device is reasonably set. First, the flushing gate plate and lifting pontoon are both embedded in the track of the flushing gate seat. Then, bullseye bearings are set in the flushing gate plate accordingly, which makes the structure reasonable. 6) The two locking plates of the locking mechanism in this device are hinged to the track by pins, and hook-shaped catches are provided to fix the large pontoon. The position of the large pontoon is stable, and it is very flexible in opening and closing. The structure is reasonable. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0017] like Figure 1 and Figure 2 As shown, a tubular automatic flushing gate device includes a water storage well 1, with a pipe 2 installed at the bottom of the water storage well 1; and a flushing gate seat 3 is also installed at the bottom of the water storage well 1, with a flushing gate plate 4 embedded in the flushing gate seat 3. The position of the flushing gate plate 4 corresponds to the position of the pipe opening of the pipe 2. The pipe 2 is placed horizontally, and the flushing gate plate 4 is placed vertically and correspondingly blocks the pipe opening of the pipe 2. The upper end of the flushing door panel 4 is also connected to a lifting pontoon 5, and a corresponding opening and closing pontoon 6 is installed above the lifting pontoon 5. A connecting rod 7 is installed at the lower end of the opening and closing pontoon 6. After the connecting rod 7 extends vertically downward, a locking mechanism is installed at the end of the rod. The locking mechanism is connected to the lifting pontoon 5. like Figure 3 and Figure 4 As shown, the small buoy 6, under the action of gravity, locks the large buoy 5 through the locking mechanism. When the small buoy 6 rises under the action of buoyancy, the locking mechanism unlocks and lifts the large buoy 5. Lifting the large buoy 5 drives the opening and closing flushing gate 4 to rise, thereby opening the pipe opening of the pipe 2.

[0018] The flushing door seat 3 is provided with tracks 8 on both sides, and the flushing door panel 4 is embedded in the tracks 8 on both sides, so that the flushing door panel 4 can move up and down within the tracks 8 on both sides.

[0019] Bullseye bearings 9 are installed on both sides of the flushing gate panel 4, and are embedded in the tracks 8 on both sides of the flushing gate panel 4. When the flushing gate panel 4 rises with the lifting float 5, a buffer pad is installed at the upper end of the track 8, and the rising distance of the flushing gate panel 4 is limited by the buffer pad.

[0020] The inner wall of the water storage well 1 is also equipped with several upper and lower supports 10. The connecting rod 7 at the bottom of the opening and closing small float 6 passes through the support 10, and the positions of the opening and closing small float 6 and the connecting rod 7 are fixed by the support 10. The length of the connecting rod 7 is adjustable. Specifically, the connecting rod 7 can be set as a telescopic structure to adjust the length accordingly.

[0021] The tracks 8 on both sides of the flushing gate 3 extend upwards, and the lifting pontoons 5 are correspondingly installed in the tracks 8 on both sides; the flushing gate 4 is connected to the lifting pontoons 5 through the connecting plate 18.

[0022] The locking mechanism has a "W" shaped structure, including two inner hinge plates 11 and two outer locking plates 12. Hinges assemblies 13 are installed at the joints between the locking plates 12 and the hinge plates 11. Hinges assemblies 13 are also installed between the two hinge plates 11, and the connecting rod 7 is installed downward on the hinge assembly 13 between the two hinge plates 11. like Figure 5 and Figure 6 As shown, the ends of the two locking plates 12 are also provided with locking hooks 14, and the sides of the lifting float 5 are respectively installed with locking plates 15. The upper ends of the locking plates 12 on both sides are hinged to the rails 8 on both sides of the flushing gate seat 3 by pins 16, so that the locking plates 12 on both sides can rotate around the position of the pins 16 as the center. The locking hooks 14 are respectively locked on the locking plates 15 to fix the lifting float 5. When the locking hooks 14 are flipped outward, the locking plates 15 are unrestricted and the lifting float 5 floats upward.

[0023] The lower end of the locking plate 12 is provided with an inwardly and downwardly extending inclined structure 17; and the latch hook 14 is provided with a corresponding inclined structure 17.

[0024] The main technical feature of this device is that both the opening and closing signals and the opening and closing operations are driven by buoyancy, unlike existing flushing devices where buoyancy is only used as the opening and closing signal, and the opening and closing operations are driven by water flow. This device can adjust the water storage capacity by adjusting the length of the connecting rod 7. This invention does not require specific structural requirements for the front end of the flushing device pipeline, making it suitable for situations where the water storage well is large and the flushing pipeline is long. In practical use, this invention mainly relies on the coordination of the lifting large float 5 and the opening and closing small float 6 to achieve flushing of the pipeline 2. The opening and closing small float 6... It is mainly designed for opening and closing the large pontoon 5. In the initial state, both the small pontoon 6 and the large pontoon 5 fall down under the action of gravity. The lower end of the large pontoon 5 is connected to the flushing gate plate 4 by a connecting plate. The large pontoon 5 and the flushing gate plate 4 are respectively embedded in the tracks 8 on both sides of the flushing gate seat 3. In the original state, the connecting rod 7 at the lower end of the small pontoon 6 extends downward and is connected to the locking mechanism. In this utility model, the locking mechanism is mainly used to realize the locking and unlocking of the large pontoon 5.

[0025] like Figure 5 As shown, the locking mechanism includes two inner hinge plates 11 and two outer locking plates 12. The plates are connected by hinge components 13 and installed accordingly. The connecting rod 7 is also installed between the two hinge plates 11. The setting of the locking mechanism in this utility model is very important. The structural setting of the two outer locking plates 12 is also very important. First, locking hooks are set at the ends of the locking plates 12. In addition, locking plates 15 are set on both sides of the lifting float 5. The position of the locking plates 15 corresponds to the position of the locking hooks. More importantly, the locking plates 12 need to be hinged and fixed to the track 8 by pins 16 so that the locking plates 12 on both sides have a pivot point for rotation.

[0026] When cleaning water is poured into the reservoir 1, and the water level submerges the large lifting pontoon 5, even though the large lifting pontoon 5 rises due to buoyancy, the locking plate 15 is locked onto the locking hook due to the locking mechanism, and the position of the large lifting pontoon 5 remains fixed. However, when clean water continues to be poured in, and the water level rises to the position of the small opening and closing pontoon 6, the small opening and closing pontoon 6 will rise with the water level under the action of buoyancy, such as... Figure 6 As shown, when the small buoy 6 rises, it drives the connecting rod 7 to rise, causing the two inner hinge plates 11 and the two outer locking plates 12 to move together, causing the locking plates 12 to flip outwards. This, in turn, causes the locking hooks to flip outwards, releasing the lifting mechanism of the large buoy 5. When the locking plate 15 is unrestrained, the lifting float 5 rises under the action of buoyancy, thereby driving the flushing gate 4 to open the pipe opening, and water enters the pipe 2 to flush the pipe 2.

[0027] Furthermore, since the flushing gate plate 4 is embedded in the tracks 8 on both sides of the flushing gate seat 3 through the bullseye bearing 9, when the flushing gate plate 4 is raised to open the pipe opening, the upper end of the track 8 is equipped with a buffer pad. Under the restriction of the buffer pad, the position is fixed until the water level drops to the position of the lifting float 5. The lifting float 5 resets under the action of gravity, which drives the flushing gate plate 4 to seal the pipe opening. The locking mechanism also resets accordingly, and the next water injection and flushing of the water storage well 1 continues. The overall structure can realize the flushing of the pipe 2, and the structural design is reasonable.

[0028] The above-described specific embodiments are merely preferred embodiments of this utility model and are not intended to limit the implementation of this utility model or the scope of the claims. All equivalent changes and modifications made in accordance with the scope of protection of this utility model patent application should be included within the scope of this utility model patent application.
