Description

Technical Field

[0001] The utility model relates to the technical field of liquid level detection equipment, in particular to a sewage level detection device in a sewage pipeline well. Background Art

[0002] Sewage pipes are specially used to transport urban sewage. Sewage wells are set up at the intersection of sewage pipes. The function of sewage wells is to discharge and collect sewage and facilitate regular inspections, cleaning of debris and subsequent maintenance by maintenance personnel. In the daily maintenance of sewage pipe wells, it is necessary to conduct liquid level detection on the sewage inside the sewage pipe wells. The water level is the most intuitive factor reflecting the water conditions of the water body. Its changes are mainly caused by the increase or decrease of water volume in the water body. Liquid level detection equipment is an indispensable equipment in the liquid level detection process and can clearly reflect the changes in water level.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1-8 As shown, a sewage level detection device in a sewage pipe well includes a mesh tube 1 and a float mechanism. The bottom wall of the mesh tube 1 is fixedly connected to a connecting rod 9, the top of the connecting rod 9 is fixedly connected to a tube cover 3, and the float mechanism passes through the tube cover 3. The float mechanism includes a guide tube 401, the guide tube 401 is fixed to the top of the tube cover 3, a float rod 402 is slidably connected in the guide tube 401, and the bottom end of the float rod 402 extends into the mesh tube 1 and is fixed with a float ball 403.

[0029] The net cylinder 1 is provided with a force storage rebound mechanism and a cleaning mechanism 7, the cleaning mechanism 7 includes a mounting plate 701, and a plurality of knocking rods 702 and a water-dipping plate 703 are fixedly connected to one side of the mounting plate 701 close to the inner wall of the net cylinder 1. The force storage rebound mechanism includes a sleeve 602, which is arranged along the radial direction of the net cylinder 1, and a movable rod 603 is slidably connected in the sleeve 602. A spring 604 is fixed between the sleeve 602 and the movable rod 603, and the mounting plate 701 is fixedly connected to the movable rod 603. A rotating mechanism 2 is provided between the net cylinder 1 and the cylinder cover 3, and the rotating mechanism 2 is used to drive the sleeve 602 to perform a circular motion. The force storage rebound mechanism also includes a pressure-bearing component, which is used to retract the movable rod 603 into the sleeve 602. When the sleeve 602 and the movable rod 603 perform a circular motion, the movable rod 603 The spring 604 is retracted into the sleeve 602, and the spring 604 is compressed. With the circular motion of the movable rod 603, the spring 604 will be released, so that the movable rod 603 quickly extends out of the sleeve 602, and the movable rod 603 drives the mounting plate 701 to move quickly, so that the knocking rod 702 knocks on the inner wall of the net tube 1, causing the net tube 1 to vibrate, and at the same time, the water-diverting plate 703 digs the sewage, so that the sewage is flushed out from the inside of the net tube 1, thereby recoiled on the impurities on the outer wall of the net tube 1, especially for the plastic film, which is attached to the outer wall of the net tube 1. Since the plastic film is thin and under the action of water pressure, the plastic film may be flatly attached to the net tube 1. In this case, it is difficult to remove the plastic film. The sewage can be recoiled outward, which can cause wrinkles in the plastic film or flush the plastic film from the net tube 1, thereby improving the cleaning effect.

[0030] The cylinder cover 3 is provided with a power mechanism 5 for providing power to the rotating mechanism 2. The rotating mechanism 2 is fixedly connected with a scraper 8. The scraper 8 is attached to the outer wall of the net cylinder 1. The scraper 8 makes a circular motion along with the rotating mechanism 2. The scraper 8 scrapes the outer wall of the net cylinder 1. The knocking rod 702 knocks on the net cylinder 1 and the water-diverting plate 703 diverts the sewage for backflushing, so that the scraper 8 can scrape off impurities more easily and improve the impurity cleaning effect.

[0031] The pressure-bearing assembly includes a pressure ring 605, which is connected to the inner wall of the mesh tube 1 by screws. A plurality of pressure blocks 606 are fixedly connected to the inner wall of the pressure ring 605. The pressure block 606 is triangular as a whole, and the hypotenuse of the pressure block 606 faces the center of the pressure ring 605. The plurality of pressure blocks 606 are distributed equidistantly around the circumference. The movable rod 603 contacts the hypotenuse of the pressure block 606. During the circular motion of the movable rod 603, the movable rod 603 is squeezed by the hypotenuse of the pressure block 606, causing the movable rod 603 to retract into the sleeve 602. When the movable rod 603 is disengaged from the pressure block 606, the spring 604 rebounds, causing the movable rod 603 to quickly extend out of the sleeve 602.

[0032] The rotating mechanism 2 includes a swivel 201, and the top and bottom of the swivel 201 are respectively slidably connected with a first fixed ring 202 and a second fixed ring 203. The first fixed ring 202 is fixedly connected to the cylinder cover 3, and the second fixed ring 203 is fixedly connected to the net cylinder 1. The force storage rebound mechanism also includes a connecting plate 601, which is fixedly connected to the bottom of the swivel 201, the sleeve 602 is fixed on the connecting plate 601, and the scraper 8 is fixedly connected to the outer wall of the swivel 201.

[0033] The power mechanism 5 includes a waterproof shell 501, which is fixed to the top of the barrel cover 3. A motor 502 is arranged in the waterproof shell 501, and the motor 502 is connected to the barrel cover 3 by screws. The output shaft of the motor 502 is fixedly connected to the gear 503, and the gear 503 is engaged with the inner ring gear 504. The inner ring gear 504 is fixedly connected to the inner wall of the rotating ring 201. The motor 502 drives the inner ring gear 504 to rotate through the gear 503, and the inner ring gear 504 drives the rotating ring 201 to rotate. The rotating ring 201 drives the connecting plate 601 to move in a circular motion, and the connecting plate 601 drives the sleeve 602 to move in a circular motion.

[0034] A steel ball 204 is provided between the swivel 201 and the first and second fixed rings 202 and 203. The steel ball 204 is movably embedded in the swivel 201. The provision of the steel ball 204 reduces the friction between the swivel 201 and the first and second fixed rings 202 and 203, so that the swivel 201 can rotate smoothly and steadily.

[0035] The vertical plane where the knock rod 702 is located and the vertical plane where the scraper 8 is located have a certain angle, such as Figure 7As shown, the movement direction of the knock rod 702 and the scraper 8 is clockwise, and the scraper 8 has a hysteresis relative to the movement of the knock rod 702, that is, the knock rod 702 first hits the Figure 7 Point B of the middle mesh tube 1 is knocked, and then the scraper 8 moves to point B for scraping. In this arrangement, the knocking rod 702 and the water-spraying plate 703 first knock and recoil the mesh tube 1 to loosen the impurities, and then the scraper 8 is used to scrape them, which can improve the cleaning effect.

[0036] The water-diverting plate 703 is arc-shaped and both ends of the water-diverting plate 703 are bent toward the inner wall of the net cylinder 1. Such an arrangement enables the water-diverting plate 703 to increase the diverting force of the sewage, thereby increasing the recoil force of the sewage on the net cylinder 1 and improving the cleaning effect.

[0037] Working principle: When in use, place the net tube 1 inside the sewage well and fix the net tube 1. Sewage enters the net tube 1. The float 403 rises and falls with the liquid level. The float 403 drives the float rod 402 to move up and down. The height of the float rod 402 is used to judge the liquid level.

[0038] The impurities in the sewage remain on the outer wall of the net cylinder 1, and the motor 502 drives the gear 503 to rotate, the gear 503 drives the inner ring gear 504 to rotate, the inner ring gear 504 drives the swivel 201 to rotate, the swivel 201 drives the scraper 8 to make a circular motion, and the scraper 8 scrapes the impurities on the outer wall of the net cylinder 1. At the same time, the swivel 201 drives the connecting plate 601 to make a circular motion, and the connecting plate 601 drives the sleeve 602 and the movable rod 603 to make a circular motion. During the movement of the movable rod 603, after the movable rod 603 contacts the inclined surface of the pressure block 606, the movable rod 603 gradually retracts into the sleeve 602, and the spring 604 is compressed. When the movable rod 603 contacts the bearing block 606, the spring 604 is compressed. After the pressure block 606 is disengaged, the spring 604 rebounds, causing the movable rod 603 to quickly extend out of the sleeve 602, and the movable rod 603 drives the mounting plate 701 to move quickly, causing the knocking rod 702 to knock on the mesh cylinder 1, and the mesh cylinder 1 vibrates to loosen impurities, and the water-dipping plate 703 digs the sewage, causing the sewage to rush out of the mesh cylinder 1, causing impurities such as plastic film or paper attached to the mesh cylinder 1 to move, for example, causing the plastic film to produce a certain deformation, so that it can be scraped by the scraper 8, and even the recoil of the sewage on the impurities can directly wash away the impurities. In summary, through the cooperation of the scraper 8, the knocking rod 702 and the water-dipping plate 703, impurities can be cleaned more effectively.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
