Description

Technical Field

[0001] This invention relates to the field of water supply equipment technology, and in particular to a protective door mechanism for cleaning the water storage tank of a secondary water supply equipment. Background Technology

[0002] Secondary water supply equipment refers to equipment used to treat water from the original water source and to store, pressurize, and distribute the treated water. In cities, secondary water supply networks distribute pressurized water to various user areas and connect it to the building's water pipe system. At the same time, they measure and monitor the water supply so that users and management departments can understand the water usage and water supply quality.

[0003] Water storage tanks are used to store treated water to meet peak demand or for temporary water outages and maintenance. A protective door is required on top of the water storage tank to protect the hygiene of the water inside. The protective door is usually electrically controlled to open and close. Due to the long-term storage of water in the tank, the water inside can corrode the sliding track of the protective door, affecting its service life and potentially causing obstruction to its opening and closing. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a protective door mechanism for cleaning the water storage tank of a secondary water supply equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The system includes a frame assembly, and further comprises: a first fixed rail and a second fixed rail, both mounted on the frame assembly; the first fixed rail is vertically fixed to the frame assembly, and the second fixed rail is horizontally fixed to the frame assembly; a protective door panel, slidably connected to the frame assembly, wherein multiple sets of protective door panels are provided, with two mutually opposing protective door panels forming a set; a first support rod and a second support rod are respectively provided at both ends of the protective door panel; a first bearing roller, rotatably connected to both ends of the first support rod; a second bearing roller, rotatably connected to both ends of the second support rod; a concave groove one, mounted on the first fixed rail, in which the first bearing roller rolls; a concave groove two, mounted on the second fixed rail, in which the second bearing roller rolls; a crescent-shaped plate, slidably mounted on the concave groove one, the crescent-shaped plate being in contact with the outer surface of the first bearing roller; and a U-shaped abrasive block, slidably connected in the concave groove one, for cleaning the surface of the concave groove one.

[0007] Preferably, the rack assembly is provided with a top cover, which is used to isolate the interior of the rack assembly from the outside.

[0008] Preferably, the frame assembly is provided with an electric push rod, the crossbar at the top of the frame assembly is fixedly connected to the output end of the electric push rod, and the bottom of the electric push rod is fixedly connected to the edge of the protective door panel.

[0009] Preferably, the frame assembly is provided with a lead screw, one end of which is rotatably connected to a first fixed rail, and a threaded block is threadedly connected to the lead screw.

[0010] Furthermore, a long groove is provided on the first fixed rail, and the threaded block is fixedly connected to the U-shaped abrasive block through the long groove.

[0011] Preferably, a triangular shovel is fixedly connected to one end of the U-shaped abrasive block near the first bearing roller, and the triangular shovel is in contact with the bottom surface of the concave groove.

[0012] Preferably, the frame assembly is provided with a drive unit and a plug block, which is fixedly connected to the output end of the drive unit.

[0013] Furthermore, the first support rod has a slot, and when the protective door is fully closed, the plug is inserted into the slot.

[0014] Preferably, the insert block is provided with two connecting rods, which are opposite to each other, and the crescent-shaped plate is fixedly connected to the connecting rods, and the two crescent-shaped plates completely enclose the first bearing roller.

[0015] Furthermore, an opening is provided in the middle of the first fixed rail. When the protective door is fully closed, the two first bearing rollers are placed in the opening, and a scraper is fixedly connected to the crescent-shaped plate.

[0016] Compared with the prior art, the present invention provides a protective door mechanism for cleaning the water storage tank of a secondary water supply equipment, which has the following beneficial effects:

[0017] 1. The protective door mechanism for cleaning the water storage tank of secondary water supply equipment controls the opening and closing of the protective door by pushing or pulling the edge of the protective door panel. During the opening and closing of the protective door panel, the U-shaped abrasive block polishes and cleans the surface of the concave groove, so that the protective door panel can open and close normally.

[0018] 2. The protective door mechanism for cleaning the water storage tank of the secondary water supply equipment uses a U-shaped abrasive block to move within the concave groove. This not only allows the U-shaped abrasive block to grind and remove rust from the surface of the concave groove, but also allows the triangular scraper to scrape away dust and other dirt from the concave groove.

[0019] 3. The protective door mechanism for cleaning the water storage tank of the secondary water supply equipment can fix the protective door plate by controlling the insertion of the plug into the slot. The crescent plate can also clean the surface of the first bearing roller. When the plug is removed from the slot, the scraper can also remove dust and other dirt in the concave groove, keeping the inside of the concave groove clean, so that the protective door plate can open and close more smoothly.

[0020] The parts of the protective door mechanism for cleaning the water storage tank of the secondary water supply equipment that are not involved are the same as or can be implemented using existing technology. The present invention can remove rust from the first fixed rail on which the protective door plate is installed, and at the same time remove dirt from the first fixed rail, thus protecting the hygiene of the water source in the water storage tank.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] In the description of this invention, 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 invention 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 invention.

[0032] Example 1:

[0033] Reference Figures 1-8 The system includes a frame assembly 1, and further includes: a first fixed rail 5 and a second fixed rail 6, both mounted on the frame assembly 1; the first fixed rail 5 is vertically fixed to the frame assembly 1, and the second fixed rail 6 is horizontally fixed to the frame assembly 1; a protective door panel 4, slidably connected to the frame assembly 1, with multiple sets of protective door panels 4, two opposing protective door panels 4 forming a set; a first support rod 14 and a second support rod 15 respectively at both ends of the protective door panel 4; a first bearing roller 7, rotatably connected to both ends of the first support rod 14; and a second shaft... The bearing roller 18 is rotatably connected to both ends of the second support rod 15; the concave groove 502 is set on the first fixed rail 5, and the first bearing roller 7 rolls in the concave groove 502; the concave groove 601 is set on the second fixed rail 6, and the second bearing roller 18 rolls in the concave groove 601; the crescent plate 13 slides on the concave groove 502, and the crescent plate 13 is in contact with the outer surface of the first bearing roller 7; the U-shaped abrasive block 16 is slidably connected in the concave groove 502 and is used to clean the surface of the concave groove 502.

[0034] In this invention, when the protective door panel 4 is closed, by pushing one end of the protective door panel 4 with the second support rod 15, the first bearing roller 7 drives the first support rod 14 to slide towards the center of the first fixed rail 5, and the second bearing roller 18 drives the second support rod 15 to move downwards towards the second fixed rail 6. When the second bearing roller 18 moves to the bottom end of the second fixed rail 6, the protective door panel 4 is completely closed. Each pair of opposing protective door panels 4 cooperate with each other, and multiple sets of such protective door panels 4 can jointly cover the top of the water storage tank to prevent dust and other debris from falling into the water storage tank and protect the hygiene of the water used in the water storage tank.

[0035] When the protective door panel 4 is opened, by pulling one end of the protective door panel 4 with the second support rod 15, the first bearing roller 7 drives the first support rod 14 to slide towards the end of the first fixed rail 5, and the second bearing roller 18 drives the second support rod 15 to move upward towards the second fixed rail 6. By controlling the upward movement distance of the second bearing roller 18 in the concave groove 601, the degree of opening of the protective door panel 4 is controlled. Due to the obstruction of the U-shaped frosted block 16, the first bearing roller 7 will not slide to the outermost end of the first fixed rail 5.

[0036] When the protective door panel 4 is opened and closed, the U-shaped abrasive block 16 slides in the concave groove 502. The U-shaped abrasive block 16 can polish and remove rust from the surface of the concave groove 502. The outer surface of the U-shaped abrasive block 16 can be made of a fine sandpaper-like material, which can polish minor rust.

[0037] Due to the obstruction of the U-shaped abrasive block 16, the first bearing roller 7 will not slide to the outermost edge of the concave groove 502, but the U-shaped abrasive block 16 can reach the outermost edge of the concave groove 502. The two U-shaped abrasive blocks 16 in the concave groove 502 cooperate with each other to polish and remove rust from the entire concave groove 502.

[0038] The protective door panel 4 can be smoothly opened and closed via the first bearing roller 7 and the second bearing roller 18.

[0039] When the protective door panel 4 is opened and closed, the U-shaped abrasive block 16 can move synchronously with the protective door panel 4 or it can not move synchronously with the protective door panel 4. When the protective door panel 4 is closed, the U-shaped abrasive block 16 can slide in the concave groove 502 on its own to polish and remove rust from the surface of the concave groove 502.

[0040] Example 2:

[0041] Reference Figures 1-8 The frame assembly 1 is provided with a top cover 2, which is used to isolate the interior of the frame assembly 1 from the outside world; the frame assembly 1 is provided with an electric push rod 3, the crossbar at the top of the frame assembly 1 is fixedly connected to the output end of the electric push rod 3, and the bottom of the electric push rod 3 is fixedly connected to the side of the protective door panel 4.

[0042] In this invention, the top cover 2 is located at the top of the frame assembly 1. The top cover 2 serves as the first line of protection for the water storage tank, and at the same time, the top cover 2 can also protect the lifting platform and the transverse module inside the frame assembly 1.

[0043] When the electric push rod 3 is working, it pulls and pushes the edge of the protective door panel 4 to open or close the protective door panel 4.

[0044] With the output end of the electric actuator 3 facing upwards, the amount of water vapor from the water tank entering the electric actuator 3 can be reduced, which can extend the service life of the electric actuator 3 and make the electric actuator 3 work more reliably.

[0045] Example 3:

[0046] Reference Figures 1-8 The frame assembly 1 is provided with a lead screw 8, one end of which is rotatably connected to the first fixed rail 5. A threaded block 9 is threadedly connected to the lead screw 8. A long groove 501 is provided on the first fixed rail 5, and the threaded block 9 is fixedly connected to the U-shaped abrasive block 16 through the long groove 501.

[0047] In this invention, a servo motor drives the lead screw 8 to rotate on the frame assembly 1. When the lead screw 8 rotates, the threaded block 9, which is threaded onto the lead screw 8, moves on the lead screw 8. By controlling the rotation direction of the lead screw 8, the threaded block 9 is controlled to move left and right. The square threaded block 9 fits against the first fixed rail 5 and cooperates with the long groove 501, so that the threaded block 9 does not rotate with the lead screw 8. When the threaded block 9 moves, it drives the U-shaped abrasive block 16 to move synchronously, so that the U-shaped abrasive block 16 polishes and removes rust from the surface of the concave groove 502, so as to avoid rust on the surface of the concave groove 502 and affect the opening and closing of the protective door panel 4.

[0048] Example 4:

[0049] Reference Figures 1-8 A triangular shovel plate 17 is fixedly connected to one end of the U-shaped abrasive block 16 near the first bearing roller 7. The triangular shovel plate 17 is in contact with the bottom surface of the concave groove 502.

[0050] In this invention, when the U-shaped abrasive block 16 moves to polish and remove rust from the surface of the concave groove 502, it can also remove dust and other dirt from the surface of the concave groove 502.

[0051] When the U-shaped abrasive block 16 moves toward the center of the concave groove 502, the triangular shovel 17 can push the dust and other dirt on the surface of the concave groove 502 to the center of the concave groove 502. Since the end of the triangular shovel 17 near the center of the concave groove 502 is inclined, when the triangular shovel 17 moves away from the center of the concave groove 502, the dust and other dirt will not follow the triangular shovel 17, so that the dust and other dirt will only remain in the center of the concave groove 502.

[0052] Example 5:

[0053] Reference Figures 1-8 The frame assembly 1 is provided with a drive unit 10 and a plug 11, which is fixedly connected to the output end of the drive unit 10. The first support rod 14 has a slot 20. When the protective door 4 is completely closed, the plug 11 is inserted into the slot 20. The plug 11 is provided with two connecting rods 12, which are opposite to each other. The crescent plate 13 is fixedly connected to the connecting rod 12. The two crescent plates 13 completely enclose the first bearing roller 7. The first fixed rail 5 has an opening 19 in the middle. When the protective door 4 is completely closed, the two first bearing rollers 7 are placed in the opening 19. The crescent plate 13 is fixedly connected with a scraper 21.

[0054] In this invention, the drive unit 10 can be a cylinder or an electric actuator, used to control the insertion block 11 to be inserted into or disengaged from the slot 20;

[0055] When the protective door 4 is completely closed, the insert block 11 is inserted into the slot 20 to fix both ends of the protective door 4. When the water bubbles in the water tank clean the inside of the water tank, the water flow impacts the protective door 4, but it will not cause the protective door 4 to open or generate large vibrations, thus protecting the lifting platform and transverse module on the frame assembly 1.

[0056] When the insert 11 is inserted into the slot 20, the two moon plates 13 also wrap around the first bearing roller 7, which can clean the surface of the first bearing roller 7, ensuring that the first bearing roller 7 rolls smoothly, thereby making the protective door panel 4 open and close smoothly without jamming.

[0057] When the insert 11 is disengaged from the slot 20, the two moon plates 13 drive the scraper 21 to disengage. The scraper 21 removes the dust and other dirt left in the center of the concave groove 502. A collection device can be provided at the opening 19 to collect the dust and other dirt. The scraper 21 is made of soft material and can abut against the triangular scraper 17. When the U-shaped abrasive block 16 is placed in the center of the concave groove 502, the scraper 21 can move in and out without being blocked by the triangular scraper 17. At the same time, the scraper 21 can also remove the dust attached to the scraper 21 and keep the triangular scraper 17 clean.

[0058] The crescent plate 13 may have a channel. By introducing lubricating oil into the channel, lubricating oil can be applied to the surface of the first bearing roller 7 when the insert block 11 is inserted into or removed from the slot 20, so that the first bearing roller 7 rolls more smoothly.

[0059] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
