Description

Technical Field

[0001] This invention relates to the field of subway drainage technology, and more specifically to installation components for an automated cleaning and maintenance subway drainage system. Background Technology

[0002] As a crucial component of urban rail transit infrastructure, the reliability of subway drainage systems directly impacts subway operational safety. Traditional subway drainage systems typically employ fixed drainage ditches and grating covers, which suffer from the following technical drawbacks: First, the grating openings are easily clogged by leaves, garbage, and other debris, requiring regular manual cleaning, resulting in low maintenance efficiency and affecting normal drainage function; second, the drainage rate of fixed covers is limited during heavy rain, easily leading to platform flooding; and third, existing systems lack emergency backflow prevention mechanisms, posing a risk of rainwater backflow during extreme weather conditions. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a reasonably designed and easy-to-use automatic cleaning and maintenance installation component for a subway drainage system. It achieves automatic drainage and anti-clogging through a flip-up drain cover and a cleaning mechanism, increases drainage volume and prevents backflow during heavy rain, and facilitates maintenance by using a screw lifting structure, thereby improving drainage efficiency and reducing manual maintenance costs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it comprises a drainage pool, a mounting plate, and a drain cover plate; the mounting plate is embedded in the outer bottom wall of the drainage pool, and a drain cover plate is embedded in the upper side of the interior of the drainage pool; drain outlets are provided on both the left and right side walls of the drainage pool; it further comprises:

[0005] The push screws consist of four screws, which are symmetrically connected to the front and rear side walls of the drainage pool in pairs via threads. The lower end of the push screw passes through the lower side wall of the drainage pool and is screwed into the mounting plate via bearings. The ends of two adjacent push screws located in the mounting plate are connected by a synchronous pulley transmission assembly.

[0006] A drive motor is embedded and fixed in the mounting plate, and the output shaft of the drive motor is connected to one of the drive screws through a synchronous pulley transmission assembly;

[0007] The flipping mechanism consists of two parts, which are respectively installed on both sides of one side wall of the drainage pool. The flipping mechanism is connected to the drain cover.

[0008] The cleaning mechanism is installed in the drainage pool and is configured to cooperate with the drain cover. The drain cover is equipped with a sealing mechanism, which is connected to the drainage pool.

[0009] The above technical solution utilizes a drainage cover to drain rainwater. When drainage is not required, the drainage cover is cleaned by a cleaning mechanism. When rainwater accumulates, a lifting mechanism rotates the drainage cover, opening the drainage pool and accelerating drainage. During rotation, the drainage cover can be sealed by a sealing mechanism to reduce the speed at which rainwater enters the subway. When maintenance or cleaning of the drainage pool is required, a drive motor is activated. The drive motor drives a lead screw through a synchronous wheel transmission assembly, which in turn drives three other lead screws to rotate. These lead screws move the drainage pool upwards, facilitating maintenance.

[0010] As a further improvement of the present invention, a sealing ring is sleeved and fixed on the upper side of the outer side of the drainage pool, and the sealing gasket of the bottom wall of the sealing ring is set to abut against the installation frame on the ground of the subway entrance.

[0011] The above technical solutions can increase the sealing between the outer wall of the drainage pool and the ground sewer opening.

[0012] As a further improvement of the present invention, the flipping mechanism includes:

[0013] A rotating shaft is fixed to the rear side of one side wall of the drain cover, and the rotating shaft is screwed into the two side walls of the drainage pool through bearings.

[0014] The drive shaft is screwed into the side wall of the drainage pool via bearings. The drive shaft is connected to the rotating shaft via a synchronous gear transmission assembly. A driven gear is sleeved and fixed on the drive shaft.

[0015] A rack is meshed with one side of the driven gear, and a push block is fixed to the lower side of the rack. The push block is movably disposed inside the side wall of the drainage pool.

[0016] An electric push rod is embedded and fixed in the side wall of the drainage pool, and the piston rod of the electric push rod is fixedly connected to the bottom wall of the push block.

[0017] With the above technical solution, when it is necessary to open the leak cover, the electric push rod is activated. The electric push rod drives the rack to move upward through the push block. The rack drives the drive shaft to rotate through the driven gear. The drive shaft drives the rotating shaft to rotate through the synchronous wheel transmission assembly. The rotating shaft drives the leak cover to rotate.

[0018] As a further improvement of the present invention, several protruding strips are fixed at equal intervals on the upper surface of the drain cover plate, and the two ends of the lower side wall of the protruding strips are engaged with the top wall of the drainage pool. Water level sensors are symmetrically arranged on one side wall of the protruding strips, and the water level sensors are connected to the electric push rod.

[0019] With the above technical solution, when water accumulates on the leak cover and the water level is at the position of the water level sensor, the water level sensor transmits a signal to the electric push rod, thus eliminating the need for manual operation of the electric push rod.

[0020] As a further improvement of the present invention, the cleaning mechanism includes:

[0021] The movable plate is located inside the drainage tank. The front and rear side walls of the movable plate abut against the front and rear inner walls of the drainage tank, respectively. Several rotating tubes are equidistantly connected to the movable plate by bearings.

[0022] The cleaning rods are of several types, and each type is installed in a corresponding manner inside the rotating tube. The brush at the upper end of the cleaning rod is inserted into the strip groove on the drain cover.

[0023] The drive rod is screwed into the movable plate via bearings, and the drive rod is connected to several rotating tubes in a one-to-one correspondence via several worm gear pairs;

[0024] A drive mechanism is provided inside the drainage pool and is connected to a drive rod and a moving plate.

[0025] Through the above technical solution, the drive mechanism drives the moving plate to move. During the movement of the moving plate, the drive mechanism drives the drive rod to rotate. The drive rod drives the rotating tube through the worm gear pair. The rotating tube drives the cleaning rod to rotate. During the rotation of the cleaning rod, the moving plate drives it to move, which facilitates the cleaning of the leak cover and avoids the phenomenon of the leak cover becoming blocked.

[0026] As a further improvement of the present invention, the driving mechanism includes:

[0027] Support bars, there are two support bars, which are symmetrically inserted through both sides of the movable plate. The two side walls of the support bars are respectively fixed to the left and right inner walls of the drainage pool.

[0028] The drive screw is embedded inside the support bar on one side. The nut on the drive screw passes through the strip groove on the lower side wall of the support bar and is fixedly connected to the moving plate. The two ends of the drive screw are screwed into the two side walls of the drainage pool through bearings.

[0029] The drive motor is embedded and fixed in one side wall of the drainage pool, and the output shaft of the drive motor is fixedly connected to one end of the drive screw.

[0030] The linkage gear is sleeved and fixed on one end of the drive rod, and the upper side of the linkage gear is meshed in the tooth groove at the bottom of the adjacent support bar.

[0031] With the above technical solution, the drive motor is started, which drives the drive screw to rotate. The drive screw drives the moving plate to move through the screw nut on it. The moving plate drives the cleaning rod and the drive rod to move. During the movement, the linkage gear on the drive rod meshes with the tooth groove on the support bar, thereby causing the linkage gear to rotate. The linkage gear drives the drive rod to rotate.

[0032] As a further improvement of the present invention, the lower end of the cleaning rod passes through the lower end of the rotating tube and is suspended on the lower side of the moving plate. The strip groove on the inner ring wall of the rotating tube is inserted into the strip groove on the outer ring wall of the cleaning rod. An installation strip is provided on the lower side of the moving plate. The installation strip is screwed to the lower end of the cleaning rod through a bearing. The front and rear sides of the upper surface of the installation strip abut against the guide frame respectively. The two ends of the guide frame are inclined downward. Several tension springs are fixed at equal intervals on the top wall of the guide frame. The tension springs are sleeved on the lower end of the cleaning rod one by one. The upper end of the tension springs is fixed on the bottom wall of the moving plate.

[0033] With the above technical solution, when the movable plate moves, the cleaning rod drives the installation strip to move. The installation strip abuts against the guide frame. When cleaning is not required, the movable plate is moved to one side inside the drainage pool. At this time, the installation strip moves downward under the guidance of the inclined side of the guide frame. The installation strip drives the cleaning rod to move downward, so that the cleaning rod moves out of the drain cover, thus not affecting the rotation of the drain cover.

[0034] As a further improvement of the present invention, a support frame is fixed on the upper side inside the drainage pool. The support frame is arranged in a "U" shape, and the top wall of the support frame is engaged with the bottom wall of the drain cover.

[0035] The above technical solution allows the drain cover to be supported by a support frame, increasing its service life.

[0036] As a further improvement of the present invention, the blocking mechanism includes:

[0037] The sealing plate consists of several plates, which are equidistantly embedded in the drain cover plate. The sealing plate is inserted into the strip groove on the drain cover plate to cooperate with it.

[0038] The sealing screws consist of two screws, which are symmetrically connected to the two sides of the leak cover plate via bearings. The two sides of the sealing plate are respectively connected to the sealing screws on both sides via threads. The two sealing screws are connected to each other via a synchronous pulley transmission assembly.

[0039] The fixing rod is located inside a rotating shaft on one side. One end of the fixing rod passes through one end of the rotating shaft and is fixed to the inner wall of the drainage pool. The other end of the fixing rod passes through the rotating shaft and is located on the drain cover. The rotating shaft is connected to the adjacent sealing screw through a worm gear pair.

[0040] With the above technical solution, when the leak cover rotates, it drives the sealing screw to rotate around the axis of the rotating shaft. At the same time, with the cooperation of the worm gear pair, the sealing screw rotates on its own axis. During the rotation, it can drive the sealing plate to one side of the strip-shaped leak groove, so that the sealing plate seals the strip-shaped leak groove. After the leak cover rotates upward, it forms a sealing plate, preventing rainwater from flowing into the subway.

[0041] As a further improvement of the present invention, a guide plate is fixed on the inner bottom wall of the drainage pool, and the two sides of the upper surface of the guide plate are inclined downward and located on the lower side inside the drainage outlet.

[0042] The above technical solution facilitates the guiding and discharge of water from inside the drainage tank.

[0043] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0044] 1. The drain cover allows rainwater to drain, and the cleaning mechanism automatically cleans debris from the gaps; when water accumulates, the flip-up mechanism quickly opens the drain cover, and the sealing mechanism simultaneously prevents backflow, improving drainage efficiency and safety.

[0045] 2. The water level sensor monitors the water level and automatically triggers the electric push rod to lift the leak cover, accelerating drainage during heavy rain and reducing the risk of water entering the subway without manual operation;

[0046] 3. The pump motor lifts and lowers the drainage tank for easy inspection of the internal structure; the sealing ring fits snugly against the ground mounting frame to prevent leakage, balancing ease of maintenance and waterproof performance.

[0047] 4. The rotating brush cleaning cover is driven by a linkage gear, and the guide frame automatically extends and retracts the cleaning rod without affecting the cover's flipping. The structure is compact and the functions are complete. Attached Figure Description

[0083] Example 5:

[0084] See Figure 8 As shown, based on Embodiment 2, the blocking mechanism 8 includes:

[0085] The sealing plate 8-1 consists of several pieces, which are equidistantly embedded in the drain cover plate 3. The sealing plate 8-1 is inserted into the strip groove on the drain cover plate 3.

[0086] The sealing screws 8-2 are two in number and are symmetrically connected to the two sides of the leak cover plate 3 by bearings. The two sides of the sealing plate 8-1 are respectively connected to the sealing screws 8-2 on both sides by threads. The two sealing screws 8-2 are connected to each other by a synchronous pulley transmission assembly.

[0087] The fixing rod 8-3 is located inside the rotating shaft 6-1 on one side.

The rotating shaft 6-1 is connected to the adjacent sealing screw 8-2 through a worm gear pair.

[0088] When using this invention, rainwater is drained through the drain cover 3. When drainage is not required, the drive mechanism 7-5 moves the moving plate 7-1. During the movement of the moving plate 7-1, the drive motor 7-5-3 is activated. The drive motor 7-5-3 drives the drive screw 7-5-2 to rotate. The drive screw 7-5-2, through its nut, drives the moving plate 7-1 to move. The moving plate 7-1 drives the cleaning rod 7-3 and the drive rod 7-4 to move. During the movement of the drive rod 7-4, the linkage gear 7-5-4 on it meshes with the tooth groove on the support bar 7-5-1, thereby causing the linkage gear 7-5-4 to rotate. -4 drives the drive rod 7-4 to rotate, and the drive rod 7-4 drives the rotating tube 7-2 through the worm gear pair. The rotating tube 7-2 drives the cleaning rod 7-3 to rotate. During the rotation, the cleaning rod 7-3 moves through the moving plate 7-1, which facilitates the cleaning of the drain cover 3 and prevents it from becoming blocked. When rainwater accumulates and the drain cover 3 needs to be opened, the moving plate 7-1 moves, which in turn drives the mounting strip 12 to move through the cleaning rod 7-3. The mounting strip 12 abuts against the guide frame 13. When cleaning is not required, the moving plate 7-1 is moved to one side inside the drainage tank 1. At this time, the mounting strip 12 is tilted on one side of the guide frame 13. Guided by the side, it moves downward, and the mounting strip 12 drives the cleaning rod 7-3 downward, so that the cleaning rod 7-3 moves out of the drain cover 3, thus not affecting the rotation of the drain cover 3. The electric push rod 6-6 is activated, and the electric push rod 6-6 drives the rack 6-4 upward through the push block 6-5. The rack 6-4 drives the drive shaft 6-2 to rotate through the driven gear 6-3. The drive shaft 6-2 drives the rotating shaft 6-1 to rotate through the synchronous gear transmission assembly. The rotating shaft 6-1 drives the drain cover 3 to rotate, so that the drainage pool 1 is in a fully open state, which speeds up the drainage speed. When the drain cover 3 rotates, it drives the sealing screw 8-2 to rotate the shaft 6-1. The shaft rotates around a center point, and with the cooperation of the worm gear pair, the sealing screw 8-2 rotates. During the rotation, it drives the sealing plate 8-1 to one side of the strip-shaped leakage channel, thereby sealing the strip-shaped leakage channel. After the leakage cover plate 3 rotates upward, the sealing plate 8-1 is formed, reducing the speed at which rainwater enters the subway. When maintenance and cleaning of the drainage pool 1 are required, the drive motor 5 is started. The drive motor 5 drives the drive screw 4 to rotate through the synchronous wheel transmission assembly. The drive screw 4 drives the other three drive screws 4 to rotate through the synchronous wheel transmission assembly. The drive screw 4 drives the drainage pool 1 to move upward, thus facilitating maintenance.

[0089] Compared with the prior art, the beneficial effects of this specific embodiment are as follows:

[0090] 1. Daily rainwater drainage is achieved through the drain cover 3, and the cleaning mechanism 7 automatically removes debris from the gaps in the cover to prevent blockage. When water accumulates, the flipping mechanism 6 quickly opens the cover to increase the drainage volume, and the sealing mechanism 8 simultaneously prevents rainwater from flowing back in, significantly improving drainage efficiency and safety.

[0091] 2. The water level sensor 11 on the leak cover 3 monitors the water level in real time and automatically triggers the electric push rod 6-6 to drive the lifting mechanism 6 without manual intervention, ensuring timely and accelerated drainage during heavy rain and reducing the risk of subway flooding.

[0092] 3. The motor 5 drives the screw to lift the drainage tank 1, which facilitates the inspection and maintenance of the internal structure; the sealing ring 9 fits tightly with the ground mounting frame to effectively prevent rainwater leakage, and takes into account both maintenance convenience and long-term waterproof performance.

[0093] 4. The cleaning mechanism 7 uses a linkage gear 7-5-4 and worm gear transmission to drive the rotating brush to thoroughly clean the cover plate; the guide frame 13 is designed to automatically extend and retract the cleaning rod 7-3, which not only ensures the cleaning effect but also does not hinder the flipping of the cover plate. The structure is compact and the functions are complete.
