DETAILED DESCRIPTION

[0029] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0030] Reference Figures 1 to 9 As shown, the present invention provides an automatic anti-sedimentation drainage device for municipal bridges, comprising a transfer pool 1, a drainage pipe 2, and a fence plate 3. The fence plate is provided at the top of the transfer pool, and a plurality of drainage pipes are connected to the bottom of the transfer pool. It also comprises an anti-sedimentation device 4, a cleaning device 5, and a stacking device 6. Two sets of first horizontal chutes 7 and second horizontal chutes 8 at different heights are provided in the transfer pool, with the first horizontal chutes being higher than the second horizontal chutes. The anti-sedimentation device is detachably fixed in the first horizontal chute provided above the drainage pipe, and an anti-sedimentation device is provided between the drainage pipe and the transfer pool. The cleaning device is provided in the second horizontal chute in a sliding connection, with the bottom surface of the cleaning device in close contact with the bottom surface of the transfer pool. The stacking device is provided between the fence plate and the anti-sedimentation device to guide the sediment falling into the transfer pool to the middle position of the bottom of the transfer pool.

[0031] Furthermore, the anti-sedimentation device includes a limiting cylinder 402, a stirring disc 408, a connecting rod assembly, a motor 403, and a fixed bracket assembly. The limiting cylinder is located at the connection between the drain pipe and the transfer tank. A plurality of through holes 406 for connecting the drain pipe and the transfer tank are provided at the bottom of the limiting cylinder. Water flows from the transfer tank into the drain pipe through the through holes. The stirring disc is located in the limiting cylinder. One end of the connecting rod assembly is connected to the stirring disc, and the other end of the connecting rod assembly is connected to the output shaft of the motor. The motor is fixed to the fixed bracket assembly, and the fixed bracket assembly is detachably fixed in the first horizontal chute above the drain pipe. When the motor is started, the energy of the motor comes from the photovoltaic panel on the roadside. The motor will drive the connecting rod assembly to rotate, and the connecting rod assembly will drive the stirring disc to break up the sediment on the inner wall of the limiting cylinder. The broken sediment is impelled by the water flow, thereby facilitating the automatic processing of the sediment.

[0032] Furthermore, a concave limiting groove 401 is provided at the connection between the drain pipe and the transfer tank, and a protrusion corresponding to the concave is provided on the outer wall of the limiting cylinder. The limiting cylinder is clamped in the limiting groove through the concave and the protrusion.

[0033] Furthermore, the connecting rod assembly includes a stirring rod 407, a first spring 411, a sliding rod 410 and a screw block 409. The stirring rod adopts a hollow structure. One end of the sliding rod is fixedly connected to the output shaft of the motor through the screw block. The other end of the sliding rod is placed in the inner cavity of one end of the stirring rod, and the sliding rod can only move axially in the inner cavity of the stirring rod. The other end of the stirring rod is fixed on the stirring disk. One end of the first spring is fixed on the screw block, the middle part of the first spring is sleeved on the sliding rod, and the other end of the first spring is fixed on the stirring rod. The first spring is in a compressed state. By setting the first spring, the effect of driving the stirring rod to move away from the screw block is achieved. By setting the first spring, the first spring has the effect of driving the stirring rod to drive the stirring disk to fit on the bottom wall of the limiting cylinder, further improving the efficiency of crushing the sediment. The protrusion on the limiting cylinder is stuck into the inner wall of the limiting groove, reducing the phenomenon of torsion between the limiting cylinder and the limiting groove, and improving the stability of the sediment crushing process.

[0034] Furthermore, the fixed bracket assembly includes a slide 404, a rod 405, a pull block 413, and a second spring 414. The slides are symmetrically arranged, with the motor fixed in the middle of the slide, and the two ends of the slide are respectively located in the first horizontal slot. The rod, pull block, and second spring are symmetrically arranged at both ends of the slide, with a slot 412 defined in the first slot, located above the drain pipe. The rod is slidably connected to the slide, perpendicular to the first horizontal slot. One end of the rod is placed in the slot, and the other end is fixedly connected to the pull block. The second spring is sleeved on the rod, and the two ends of the second spring are respectively fixedly connected to the pull block and the slide, and the second spring is in a stretched state. Inserting the rod into the inner wall of the slot facilitates fixing the position of the slide after movement. The second spring serves to pull the pull block, driving the rod into the inner wall of the slot.

[0035] By setting up an anti-sedimentation device, the energy of the motor comes from the photovoltaic panels on the roadside. When the motor is started, the motor will drive the stirring rod to rotate, and the water flowing through the fence plate will flow into the transfer pool. The impurities in the water in the transfer pool will be filtered through the through-holes on the limit cylinder. The stirring rod on the motor will drive the stirring plate to rotate, and the stirring plate will break up the mud, dead leaves and other impurities on the inner wall of the limit cylinder. At this time, the water flow will easily wash away the broken sediment through the through-hole, thereby achieving the effect of automatic cleaning of the sediment, thereby reducing the phenomenon of sediment accumulation in the drain pipe. When the limit cylinder needs to be maintained or the through-hole needs to be cleaned, the screw block on the output end of the motor can be turned out, and the two pull blocks can be pulled to the side close to each other. The pull block will drive the rod to be pulled out from the inner wall of the slot. At this time, The slide is slid inside the transfer pool, and the stirring rod together with the limit cylinder can be taken out for maintenance and cleaning. Similar to the above steps, after the limit cylinder is maintained and cleaned, the limit cylinder is inserted into the inner wall of the limit groove, and the slide is slid. When the insertion rod inside the slide slides to the position corresponding to the slot, the pull block will be driven by the tension of the second spring on the inner wall of the slide to drive the insertion rod to be stuck in the inner wall of the slot. At this time, the position of the slide after movement can be fixed, which facilitates the docking work between the screw block and the motor. By setting an anti-sedimentation device, the motor is used to drive the stirring rod to break up the sediment at the connection position of the drain pipe and the transfer pool in time and use the water flow to easily wash away the broken sediment, thereby reducing the accumulation of sediment in the drain pipe and causing blockage of the drain pipe, and further improving the drainage effect of the drain pipe.

[0036] Furthermore, the cleaning device includes a limit frame 53, a telescopic rod 54, a third spring 55, and a scraper structure. The limit frame is arranged horizontally within the second horizontal chute, and the limit frame slides horizontally within the first horizontal chute. One end of the telescopic rod is located at the bottom of the limit frame, and the other end is located at the top of the scraper structure. The bottom end of the scraper structure is closely attached to the bottom surface of the transfer tank, and the two ends of the scraper structure are against the side walls of the transfer tank. The third spring is sleeved on the telescopic rod and is arranged in a compressed state between the limit frame and the scraper structure. The scraper mechanism slides within the transfer tank along with the limit frame. The provision of the third spring serves to drive the scraper to adhere to the bottom wall of the transfer tank.

[0037] Furthermore, the scraper structure includes a T-shaped scraper 51, a plurality of sharp blocks 52, and a sponge block 56. The bottom surface of the T-shaped scraper is attached to the bottom surface of the transfer tank, and the two side ends are against the side walls of the transfer tank. The sharp blocks are spaced apart on the side walls of the T-shaped scraper and extend to the side walls of the transfer tank. The tips of the sharp blocks face outward, and the bottoms of the sharp blocks are flush with the bottom end of the T-shaped scraper. A rectangular groove is provided in the middle of the bottom end of the T-shaped scraper. The length of the rectangular groove is consistent with the width of the transfer tank. The sponge block is clamped into the rectangular groove of the T-shaped scraper. The provision of the sharp blocks facilitates the treatment of some sediments adhering to the bottom wall of the transfer tank, thereby improving the drainage effect of the drainage device. The provision of the sponge block facilitates the wiping of the bottom wall of the transfer tank after the sediment is cleaned.

[0038] By setting a cleaning device, when sediment formed by dust accumulation in the transfer pool, the fence plate on the transfer pool is opened and the stirring rod is removed from the motor, and the limit frame on the inner wall of the transfer pool is slid. The scraper will always be fitted to the bottom wall of the transfer pool by the elastic force of the third spring on the limit frame, which improves the tightness of the fit between the scraper and the transfer pool. At this time, the scraper can scrape the sediment on the bottom wall of the transfer pool. The setting of the pointed block facilitates the scraping of some mud blocks that are tightly adhered to the bottom wall of the transfer pool, thereby improving the effect of scraping sediment, and the sponge block can wipe the bottom wall of the transfer pool after scraping, thereby improving the cleaning effect of the bottom wall of the transfer pool. The scraper can be lifted and the sponge block on the inner wall of the rectangular groove of the scraper can be replaced, thereby improving the wiping effect of the bottom wall of the transfer pool. By setting a cleaning device, it is convenient to clean the sediment on the bottom wall of the transfer pool, thereby further improving the drainage effect of the drainage device.

[0039] Furthermore, the stacking device includes barbed hooks 62, a gauze connecting rope assembly, and a pressure rod assembly. The barbed hooks are arranged at intervals at the bottom of the fence board, and the barbed hooks are arranged along the length direction of the fence board; the two sides of the gauze connecting rope assembly are respectively hung between the barbed hooks on both sides of the fence board; two groups of pressure rod assemblies are arranged in parallel and at intervals in the transfer pool, and the pressure rod assemblies are arranged along the length direction of the transfer pool; the top of the pressure rod assembly is fixed to the bottom of the fence board assembly, and the bottom of the pressure rod assembly is pressed on the gauze or the connecting rope assembly. Under the action of the pressure rod assembly, the gauze connecting rope assembly forms a structure with a trapezoidal cross-section and a hollow bottom surface.

[0040] Furthermore, the gauze connecting rope assembly includes two pieces of gauze 61 and a plurality of connecting ropes 65. One side of the gauze is hung on the barbed hook on one side of the fence plate, and the other side of the gauze is fixed with a plurality of connecting ropes at intervals. The number of connecting ropes is consistent with the number of barbed hooks on the other side of the fence plate, and the other side of the gauze is connected to the barbed hook on the other side of the fence plate through the connecting rope. The pressure rod assembly is supported on the connecting rope gauze or the connecting rope. There is a certain gap between the connecting rope sides of the two pieces of gauze, and the gap between the gauze is located above the middle of the transfer pool. By providing the gauze connecting rope assembly, the sediment flowing through the fence plate is diverted, thereby facilitating the centralized treatment of the sediment and reducing the phenomenon that the sediment is concentrated in the corners of the transfer pool and is inconvenient to treat.

[0041] Furthermore, the pressure rod assembly includes a telescopic rod 64, a pressure rod 63, a screw 67 and a screw barrel 66, and the pressure rod is arranged along the length direction of the transfer pool; a number of telescopic rods are arranged at intervals on the pressure rod, and one end of the telescopic rod is fixed on the pressure rod, and the other end is fixed on the bottom surface of the fence plate; one end of the screw barrel is fixed on the bottom surface of the fence plate, and the other end is connected to the screw by a threaded connection; a through hole is provided on the pressure rod, and the other end of the screw passes through the through hole, and a limit head is provided at the other end of the screw, the size of the limit head is larger than the tube through hole, and the distance between the pressure rod and the fence plate is adjusted by the screw.

[0042] By setting up a stacking device, the gauze hook is hung on the surface of the barbed hook. At this time, the two gauze and the connecting rope can form a "V"-shaped structure. The screw inside the screw barrel is rotated, and the screw will drive the pressure rod to squeeze the gauze, squeezing the gauze and the connecting rope into an isosceles trapezoidal structure. At this time, the sediment flowing through the fence plate can flow along the gauze to the bottom wall position in the middle of the transfer pool, which is convenient for the centralized treatment of the sediment and reduces the phenomenon that the sediment accumulates at the corners of the transfer pool and is inconvenient to treat. By setting up a stacking device, the stacking of the sediment flowing through the fence plate is facilitated, thereby facilitating the centralized treatment of the sediment and reducing the phenomenon that the sediment is concentrated at the corners of the transfer pool and is inconvenient to treat.

[0043] Working principle of the present invention:

[0044] The energy of the motor comes from the photovoltaic panels on the roadside. When the motor is started, the motor will drive the stirring rod to rotate. The water flowing through the fence plate will flow into the transfer pool. The impurities in the water in the transfer pool will be filtered through the through holes on the limit cylinder. The stirring rod on the motor will drive the stirring plate to rotate. The stirring plate will break up the mud, dead leaves and other impurities on the inner wall of the limit cylinder. At this time, the water flow will easily flush away the broken sediment through the through holes, thereby achieving the effect of automatically cleaning the sediment, thereby reducing the phenomenon of sediment accumulation in the drain pipe.

[0045] When it is necessary to maintain the limit cylinder or clean the through hole, the screw block on the output end of the motor can be turned out, and the two pull blocks can be pulled toward the side close to each other. The pull block will drive the rod to be pulled out from the inner wall of the slot. At this time, the slide can be slid inside the transfer pool. At this time, the stirring rod can be taken out together with the limit cylinder for maintenance and cleaning. Similar to the above steps, after maintenance and cleaning the limit cylinder, the limit cylinder is inserted into the inner wall of the limit slot, and the slide is slid. When the rod inside the slide slides to the position corresponding to the slot, the pull block will be pulled by the second spring on the inner wall of the slide to drive the rod to be stuck in the insert The inner wall of the groove can now fix the position of the sliding frame after movement, which facilitates the docking work between the screw block and the motor. By setting the first spring, the first spring has the effect of driving the stirring rod to drive the stirring plate to fit the bottom wall of the limiting cylinder, further improving the efficiency of breaking up the sediment, and the protrusion on the limiting cylinder is stuck into the inner wall of the limiting groove, which reduces the torsion phenomenon between the limiting cylinder and the limiting groove, and improves the stability of the sediment breaking process. When sediment formed by dust accumulates in the transfer pool, the fence plate on the transfer pool is opened and the stirring rod is removed from the motor. By setting up an anti-sedimentation device, the motor is used to drive the stirring rod to break up the sediment at the connection position of the drain pipe and the transfer pool in time and use the water flow to easily wash away the broken sediment, thereby reducing the phenomenon of sediment accumulation in the drain pipe causing blockage of the drain pipe, and further improving the drainage effect of the drain pipe.

[0046] The limit frame on the inner wall of the sliding transfer pool will always cause the scraper to fit the bottom wall of the transfer pool under the elastic force of the third spring on the limit frame, thereby improving the tightness of the fit between the scraper and the transfer pool. At this time, the scraper can scrape the sediment on the bottom wall of the transfer pool. The setting of the pointed block facilitates the scraping of some mud blocks that are tightly adhered to the bottom wall of the transfer pool, thereby improving the effect of scraping the sediment. The sponge block can wipe the bottom wall of the transfer pool after scraping, thereby improving the cleaning effect of the bottom wall of the transfer pool. The scraper can be lifted to replace the sponge block on the inner wall of the rectangular groove of the scraper, thereby improving the wiping effect of the bottom wall of the transfer pool. By setting up the cleaning device, the cleaning of the sediment on the bottom wall of the transfer pool is facilitated, thereby further improving the drainage effect of the drainage device.

[0047] Hang the gauze hook on the surface of the barbed hook. At this time, the two gauze and the connecting rope can form a "V"-shaped structure. Turn the screw inside the screw barrel, and the screw will drive the pressure rod to squeeze the gauze, squeezing the gauze and the connecting rope into an isosceles trapezoidal structure. At this time, the sediment flowing through the fence plate can flow along the gauze to the bottom wall position in the middle of the transfer pool, which is convenient for the centralized treatment of the sediment and reduces the phenomenon that the sediment accumulates at the corners of the transfer pool and is inconvenient to treat. By setting up a stacking device, it is convenient to stack the sediment flowing through the fence plate, thereby facilitating the centralized treatment of the sediment and reducing the phenomenon that the sediment is concentrated at the corners of the transfer pool and is inconvenient to treat.

[0048] The above are only preferred embodiments of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope of protection of the present invention.
