Description

Technical Field

[0001] The present invention relates to the technical field of drainage devices, and particularly to an underground drainage device for municipal engineering. Background Technique

[0002] Municipal infrastructure projects refer to the civil engineering, pipeline, and equipment installation projects of urban roads, public transportation, water supply, drainage, gas, heating, gardens, environmental sanitation, sewage treatment, garbage treatment, flood control, underground public facilities, and ancillary facilities. Among them, underground drainage is relatively important; since underground water contains a large amount of impurities such as garbage pollutants, before draining the underground water, it is necessary to filter and clean the underground water to avoid polluting the environment.

[0003] At present, the underground drainage devices generally filter by setting a filter screen. However, there are many different particulate impurities in the underground water, and the accumulation of sundries easily reduces the water passing cross-section of the drainage pipeline, thereby weakening the drainage capacity of the drainage pipeline. At the same time, the existing filter screen has a fixed position and a fixed filter hole size. During long-term use, suspended substances such as sediment and debris in the water are easily combined with oils or organic substances to form a dense cake on the filter screen. If the filter screen is not cleaned in time, sewage and sundries will adhere to the filter screen for a long time, forming stubborn stains, resulting in the blockage of the filter screen holes and affecting the drainage volume.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] In the present invention, through the arrangement of components such as the device housing, the filtering mechanism, and the moving mechanism, during the reciprocating movement of the moving mechanism driving the filtering mechanism, by reducing and increasing the aperture between the vertical rod and the horizontal rod, and the reciprocating movement of the installation frame, the attachment of sundries in the sewage to the aperture is reduced, avoiding the problem that the filter hole size structure of the existing drainage filtering device is fixed. When stains are long-term attached to the filter holes, stubborn stains are formed around the filter holes of the filter screen, and it is difficult to clean, easily causing the filter holes to be blocked and affecting the drainage volume.

[0014] In the present invention, through the arrangement of components such as the device housing, the filtering mechanism, and the moving mechanism, during the reciprocating movement of the filtering mechanism driven by the moving mechanism, when the filtering mechanism moves in the direction opposite to the water flow, the aperture of the filtering mechanism can be reduced, thereby better blocking impurities and preventing the impact of the water flow. The water flow flushes the impurities out of the larger filter holes, affecting filtration. When the water flow moves in the same direction as the filtering mechanism, the aperture of the filtering mechanism can be increased. When the moving speed of the filtering mechanism is close to the water flow velocity, the sundries will not pass through the filter screen, and the larger filter holes contribute to the flow of the water flow.

[0015] In the present invention, through the arrangement of components such as the moving mechanism, the collection assembly, and the scraping assembly, when the filtering mechanism pushes the filtered sundries to the position of the arc-shaped scraping blade, the sundries can be scraped towards the installation groove, causing the sundries to gather towards the installation groove. Under the impact of the water flow, the garbage can enter the collection cylinder through the installation groove for collection, avoiding the influence on the drainage efficiency due to the accumulation of sundries on the main drainage channel.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 to 13, the present invention provides a technical solution: an underground drainage device for municipal engineering, including a device housing 1. One side of the device housing 1 is fixedly connected with a water outlet joint 101, and the other side of the device housing 1 is fixedly connected with a water inlet joint 102. Inside the device housing 1, a filtering mechanism 2 for filtering sewage is provided. On one side inside the device housing 1, a moving mechanism 3 for driving the filtering mechanism 2 to reciprocate is provided. On one side of the inner bottom of the device housing 1, an installation groove 106 is opened, and a collection cylinder 5 is detachably installed inside the installation groove 106. It should be added here that a threaded groove is opened at one end of the installation groove 106, and the surface of one end of the collection cylinder 5 has an external thread that matches the end of the installation groove 106, so that the collection cylinder 5 is threadedly installed inside the installation groove 106. A collection assembly 4 for facilitating the collection of filtered debris is provided between the top wall of the device housing 1 and the moving mechanism 3.

[0032] In this embodiment, as Figures 1 to 13 shown, the filtering mechanism 2 includes an installation frame 201. The installation frame 201 is movably installed inside the device housing 1. The middle of the installation frame 201 has a circular through groove to facilitate the flow of sewage. Sliding sleeves 202 are fixedly installed around the installation frame 201, and one side of the sliding sleeve 202 is slidably installed on the inner wall of the device housing 1. It should be added here that sliding grooves are opened around the inner wall of the device housing 1, and one side of the sliding sleeve 202 is slidably installed in the adjacent sliding groove. A number of vertical rods 203 are slidably installed at equal intervals in the vertical direction on one side of the installation frame 201, and a number of horizontal rods 204 are slidably installed at equal intervals in the horizontal direction on one side of the installation frame 201. It should be noted that moving grooves are opened around one side of the installation frame 201, and both ends of the vertical rods 203 and the horizontal rods 204 are slidably installed in the corresponding moving grooves. During the movement of the vertical rods 203 and the horizontal rods 204, the stability of their movement is improved, and the horizontal rods 204 are arranged on one side of a number of vertical rods 203. A number of vertical rods 203 and a number of horizontal rods 204 are arranged in a staggered manner. In addition, the other side of the vertical rod 203 is arranged on the surface of one side of the installation frame 201, and through the staggered arrangement of the vertical rods 203 and the horizontal rods 204, a grid structure is formed to block debris in the underground sewage of municipal engineering. On the periphery of one side of the installation frame 201, movable plates 205 are provided, and a number of guide grooves 2051 are opened at equal intervals on the surface of the movable plates 205. Both ends of the vertical rods 203 and the horizontal rods 204 are slidably installed in the corresponding guide grooves 2051. An adjusting assembly 206 for adjusting the distance between the vertical rods 203 and the horizontal rods 204 is provided inside the sliding sleeve 202.

[0033] In this embodiment, as Figures 1 to 13As shown in the figure, the adjusting assembly 206 includes a movable rod 2061 which movably passes through the mounting frame 201. One end of the movable rod 2061 is fixedly connected to one end of the adjacent movable plate 205. The other end of the movable rod 2061 is fixedly connected with a pressing block 2062, and the pressing block 2062 is of a trapezoidal structure. A first spring 2063 is sleeved on the surface of the other end of the movable rod 2061, and both ends of the first spring 2063 are fixedly installed between the surface of one end of the pressing block 2062 and the outer wall of the mounting frame 201. Jack holes 2064 are formed on both sides of the other end of the pressing block 2062. An installation rod 2067 is fixedly installed on the inner wall of the sliding sleeve 202, and a locking pin 2065 is slidably installed on the installation rod 2067. One end of the locking pin 2065 is placed on the surface of the pressing block 2062, and guide rods 2066 are symmetrically and fixedly installed at the other end of the locking pin 2065 and penetrate to the outer wall of the sliding sleeve 202. A second spring 2068 is sleeved on the surface of the installation rod 2067, and both ends of the second spring 2068 are fixedly installed between the surface of one end of the installation rod 2067 and the inner wall of the sliding sleeve 202. Thrust rods 103 are fixedly installed around the inner wall of one side of the device housing 1, and the thrust rods 103 cooperate with the adjacent pressing blocks 2062. Pressing plates 104 are fixedly installed around the inner wall of the other side of the device housing 1, and the pressing plates 104 cooperate with the adjacent guide rods 2066.

[0034] It should be noted here that since sliding grooves are formed around the inner wall of the device housing 1, the sliding sleeve 202 is slidably installed in the sliding grooves, and the thrust rods 103 are fixedly installed at one end of the sliding grooves, and the pressing plates 104 are fixedly installed at the other end of the sliding grooves. After the filtering mechanism 2 moves in place to one end of the sliding grooves, the thrust rods 103 will press the pressing blocks 2062 in the sliding sleeve 202. At this time, the pressing blocks 2062 move so that the end of the locking pin 2065 is inserted into the corresponding jack holes 2064, locking the position of the pressing blocks 2062, thereby reducing the distance between the vertical rod 203 and the horizontal rod 204. After the filtering mechanism 2 moves in place to the other end of the sliding grooves, the guide rods 2066 press on the pressing plates 104, and the guide rods 2066 drive the locking pin 2065 to move on the installation rod 2067, so that the locking pin 2065 is disengaged from the insertion into the jack holes 2064, thereby releasing the locking of the position of the pressing blocks 2062 and increasing the distance between the vertical rod 203 and the horizontal rod 204.

[0035] During the movement of the filtering mechanism 2 driven by the moving mechanism 3, when the filtering mechanism 2 moves in place in the direction away from the water inlet joint 102, the inclined surfaces of the extrusion blocks 2062 around the mounting frame 201 are extruded against the corresponding ejector rods 103. At this time, the first spring 2063 is extruded and contracted, and the extrusion blocks 2062 approach the surface of the mounting frame 201. At the same time, the movable plates 205 around the mounting frame 201 move towards the middle. Under the guidance of the guide grooves 2051, the vertical rods 203 and the horizontal rods 204 reduce the distance between the vertical rods 203 and the horizontal rods 204. After the extrusion blocks 2062 move in place, the two jacks 2064 on the extrusion blocks 2062 are aligned with the corresponding locking pins 2065. At the same time, under the elastic push of the second spring 2068, the locking pins 2065 approach the inner wall of the sliding sleeve 202, so that the ends of the locking pins 2065 are inserted into the corresponding jacks 2064, completing the locking of the position of the movable plate 205, ensuring that after the distance between the vertical rods 203 and the horizontal rods 204 is reduced, the reduced aperture remains unchanged, and the two guide rods 2066 on the locking pins 2065 extend to the outside through the holes on the sliding sleeve 202. At this time, the moving mechanism 3 drives the filtering mechanism 2 to approach the water inlet joint 102, and the filtering mechanism 2 moves in the direction opposite to the water flow. At this time, the reduction of the aperture can better block impurities and prevent the impact of the water flow. The water flow flushes the impurities out of the larger filter holes, affecting the filtration. When the moving mechanism 3 drives the filtering mechanism 2 to move in place in the direction of the water inlet joint 102, the guide rods 2066 on the locking pins 2065 are extruded against the corresponding extrusion plates 104, and the locking pins 2065 move, so that the ends of the locking pins 2065 are disengaged from the insertion of the jacks 2064. At this time, the first spring 2063 elastically resets, pushing the extrusion blocks 2062 to move upward, so that the movable plates 205 around the mounting frame 201 move in the opposite direction at the same time. Under the guidance of the guide grooves 2051, the aperture between the vertical rods 203 and the horizontal rods 204 becomes larger. Then, during the movement of the moving mechanism 3 driving the filtering mechanism 2 in the direction away from the water inlet joint 102, the water flow moves in the same direction as the filtering mechanism 2, and by setting the moving speed of the filtering mechanism 2, it is made close to the water flow velocity, so that the sundries will not pass through the filter screen, and the larger filter holes contribute to the water flow. At the same time, by reducing and increasing the aperture between the vertical rods 203 and the horizontal rods 204, and the reciprocating movement of the mounting frame 201, the attachment of sundries in the sewage to the aperture is reduced, avoiding the problem that the filter hole size structure of the existing drainage filtering device is fixed. When stains adhere to the filter holes for a long time, stubborn stains are formed around the filter holes of the filter screen, and it is difficult to clean, easily causing filter hole blockage and affecting the drainage volume.

[0036] In this embodiment, as Figures 1 to 13As shown in the figure, the moving mechanism 3 includes a motor 301. The motor 301 is fixedly installed on the outer wall of the device housing 1. The output end of the motor 301 is fixedly connected to a rotating shaft 302. The rotating shaft 302 is rotatably installed horizontally inside the device housing 1. It should be noted here that sealing bearings are provided on the surfaces at both ends of the rotating shaft 302. The inner ring of the sealing bearing is fixedly connected to the surface of the rotating shaft 302, and the outer ring of the sealing bearing is fixedly connected to the inside of the device housing 1, which improves the rotational stability of the rotating shaft 302 and at the same time improves the sealing performance inside the device housing 1. Symmetrically fixed on the surface of the rotating shaft 302 are cam discs 303. And on one side of the cam disc 303 is provided a movable block 304. Both ends of the movable block 304 are rotatably installed with guide wheels 305. One side of the two guide wheels 305 is respectively placed on the inner wall and the outer wall of the cam disc 303. One end of the movable block 304 is hingedly installed with a moving rod 306. And one end of the moving rod 306 is fixedly installed on the surface of one side of the installation frame 201. A positioning block 307 is sleeved on the surface of the moving rod 306. And one side of the positioning block 307 is fixedly installed on the inner wall of the device housing 1.

[0037] During the reciprocating movement of the filtering mechanism 2 driven by the moving mechanism 3, the two cam discs 303 on the rotating shaft 302 driven by the output end of the motor 301 rotate. Since the end of the moving rod 306 fixedly connected to one side of the installation frame 201 is hinged with the movable block 304, and at the same time both ends of the movable block 304 are rotatably installed on the edges of the inner wall and the outer wall of the cam disc 303 through the guide wheels 305. When the cam disc 303 rotates, the movable block 304 does not rotate around the cam disc 303, but drives the moving rod 306 to move reciprocally, so that the moving rod 306 drives the installation frame 201 to move reciprocally, so as to realize the reciprocating movement of the filtering mechanism 2.

[0038] In this embodiment, as Figures 1 to 13As shown, the collection component 4 includes an L-shaped push rod 401. One side of the top wall of the device housing 1 is provided with a movable slot 105. The L-shaped push rod 401 is movably arranged through the inside of the movable slot 105. One end of the L-shaped push rod 401 penetrates to the other side inside the device housing 1. The other end of the L-shaped push rod 401 is fixedly connected with an extrusion rod 402. On the other side of a group of cam disks 303, a push block 403 is fixedly connected, and the push block 403 is matched with the extrusion rod 402. A third spring 404 is sleeved on the surface of the other end of the L-shaped push rod 401, and both ends of the third spring 404 are respectively fixedly connected between one side of the upper end of the extrusion rod 402 and the inner wall of the movable slot 105. It should be noted here that when the extrusion of the push block 403 by the extrusion rod 402 is released, the third spring 404 drives the L-shaped push rod 401 to move back to its original position. One end of the L-shaped push rod 401 is fixedly connected with a rack 405. On the other side inside the device housing 1, a rotating rod 406 is rotatably installed. It should be noted that the bottom of the rotating rod 406 is rotatably installed inside the device housing 1 through a bearing, and a guide block is rotatably installed at the upper end of the rotating rod 406. The guide block is fixedly installed on the inner wall of the device housing 1, and a gear 407 is fixedly connected to the top of the rotating rod 406. The surface of the gear 407 is meshed with the surface of the rack 405. A baffle 408 is fixedly installed at the bottom of the rotating rod 406, and one side of the baffle 408 is attached to the upper side of the installation slot 106. A scraping component 6 for scraping the filtered sundries is arranged between the surface of the upper end of the rotating rod 406 and the inner wall of the device housing 1.

[0039] During the reciprocating movement of the filtering mechanism 2 driven by the moving mechanism 3, when the filtering mechanism 2 first moves in place towards the water inlet joint 102 and then is about to move away from the water inlet joint 102, the push block 403 on a group of cam disks 303 will squeeze and push the extrusion rod 402 at the end of the L-shaped push rod 401 through rotation, causing the third spring 404 to be squeezed and contracted under force. At the same time, the rack 405 fixed on the L-shaped push rod 401 is meshed with the gear 407 on the rotating rod 406, causing the rotating rod 406 to rotate. The baffle 408 at the bottom of the rotating rod 406 flips and releases the blockage of the installation slot 106. Since the filtering mechanism 2 moves in place towards the water inlet joint 102, the sundries filtered out on one side of the filtering mechanism 2 are pushed to the position of the arc-shaped scraping piece 604 through the movement of the filtering mechanism 2. Under the impact of water flow, the garbage can enter the collection cylinder 5 through the installation slot 106 for collection.

[0040] In this embodiment, as Figures 1 to 13As shown in the figure, the scraping component 6 includes a curved groove 601, which is opened on the surface of the upper end of the rotating rod 406. A slider 602 is slidably installed on the surface of the upper end of the rotating rod 406 through the curved groove 601, and one side of the slider 602 is slidably installed on the inner wall of the device housing 1. The inner wall of the slider 602 has a guide block, and the slider 602 is slidably installed on the curved groove 601 of the rotating rod 406 through the guide block on the inner wall. The other side of the slider 602 is hingedly installed with a hinge rod 603, and one end of the hinge rod 603 is hingedly installed with an arc-shaped scraping blade 604. The bottom of the arc-shaped scraping blade 604 is rotatably installed on the inner wall of the device housing 1.

[0041] In order to improve the collection of sundries, during the rotation of the rotating rod 406, the slider 602 slidably installed at the upper end of the rotating rod 406 moves downward along the rotating rod 406 under the guidance of the curved groove 601. At this time, the hinge rod 603 hinged on the slider 602 deflects, pushing the hinged arc-shaped scraping blade 604 to deflect and swing downward with the bottom of the arc-shaped scraping blade 604 as the center of the circle, scraping the sundries towards the position of the installation groove 106. At this time, the sundries gather towards the installation groove 106, thereby further increasing the collection efficiency of the sundries.

[0042] In this embodiment, as Figures 1 to 13 shown, a sealing ring 501 is installed on the surface of the end of the collection cylinder 5 away from the baffle 408, and the outer ring of the sealing ring 501 fits with the inner wall of the installation groove 106. Through the setting of the sealing ring 501, the sealing performance between one end of the collection cylinder 5 and the device housing 1 is improved. When cleaning the sundries in the collection cylinder 5, only need to screw out the collection cylinder 5 from one end of the installation groove 106, and the sundries can be poured out, which is convenient for cleaning the sundries.

[0043] In this embodiment, as Figures 1 to 13 shown, a number of through holes are equidistantly arranged in an array on the surface of the collection cylinder 5, and a connection port 107 is opened on one side of the lower end inside the device housing 1. The through holes are communicated with the inside of the device housing 1 through the connection port 107.

[0044] After the baffle 408 is opened, the filtered sundries flow into the collection cylinder 5 inside the installation groove 106 under the impact of water flow. The excess water in the collection cylinder 5 flows into the device housing 1 through the through holes and the connection port 107. The aperture of the through holes is relatively small, which blocks the sundries. Through this collection of sundries, it is avoided that during the drainage process of municipal engineering, the drainage efficiency is affected due to the accumulation of sundries on the main drainage channel.

[0045] The usage method and advantages of the present invention: The underground drainage device for municipal engineering works as follows:

[0046] As Figures 1 to 13As shown in the figure, in the underground drainage of municipal engineering, sewage enters the interior of the device through the water inlet joint 102. The motor 301 is started, and two cam discs 303 on the rotating shaft 302 driven by the output end of the motor 301 rotate. Since the end of the moving rod 306 fixedly connected to one side of the installation frame 201 is hinged with the movable block 304, and at the same time, both ends of the movable block 304 are rotatably installed on the edges of the inner wall and the outer wall of the cam disc 303 through guide wheels 305. When the cam disc 303 rotates, the movable block 304 does not rotate around the cam disc 303, but drives the moving rod 306 to move reciprocally, thereby driving the installation frame 201 to move reciprocally by the moving rod 306;

[0047] During the movement of the installation frame 201 driven by the moving mechanism 3, when the installation frame 201 moves in place in the direction away from the water inlet joint 102, the inclined surfaces of the extrusion blocks 2062 around the installation frame 201 are extruded on the corresponding ejector rods 103. At this time, the first spring 2063 is extruded and contracted, and the extrusion blocks 2062 approach the surface of the installation frame 201. At the same time, the movable plates 205 around the installation frame 201 move closer to the middle. Under the guidance of the guide grooves 2051, the vertical rods 203 and the horizontal rods 204 are such that the distance between the vertical rods 203 and the horizontal rods 204 is reduced. After the extrusion blocks 2062 move in place, the two jacks 2064 on the extrusion blocks 2062 are aligned with the corresponding locking pins 2065. At the same time, under the elastic push of the second spring 2068, the locking pins 2065 approach the inner wall of the sliding sleeve 202, so that the ends of the locking pins 2065 are inserted into the corresponding jacks 2064, completing the locking of the position of the movable plate 205, ensuring that after the distance between the vertical rods 203 and the horizontal rods 204 is reduced, the reduced aperture remains unchanged, and the two guide rods 2066 on the locking pins 2065 extend to the outside through the holes on the sliding sleeve 202. At this time, the moving mechanism 3 drives the filtering mechanism 2 to approach the water inlet joint 102, and when the filtering mechanism 2 moves in the direction opposite to the water flow, the reduction of the aperture at this time can better block impurities and prevent the impact of water flow, and the water flow flushes the impurities out of the larger filter holes;

[0048] When the moving mechanism 3 drives the installation frame 201 to move in place in the direction of the water inlet joint 102, the guide rods 2066 on the locking pins 2065 are extruded on the corresponding extrusion plates 104, and the locking pins 2065 move, so that the ends of the locking pins 2065 are disengaged from the insertion of the jacks 2064. At this time, the first spring 2063 elastically resets and pushes the extrusion blocks 2062 to move upward, so that the movable plates 205 around the installation frame 201 move in the opposite direction at the same time. Under the guidance of the guide grooves 2051, the aperture between the vertical rods 203 and the horizontal rods 204 becomes larger. Then, when the moving mechanism 3 drives the filtering mechanism 2 to move in the direction away from the water inlet joint 102, the water flow moves in the same direction as the filtering mechanism 2, and by setting the moving speed of the filtering mechanism 2, it is made close to the water flow velocity, so that the sundries will not pass through the filter screen, and the larger filter holes are helpful for the water flow to flow;

[0049] In addition, when the filtering mechanism 2 first moves in place towards the water inlet joint 102 and then is about to move away from the water inlet joint 102, the push block 403 on a set of cam disks 303 rotates and squeezes the extrusion rod 402 at the end of the L-shaped push rod 401, causing the third spring 404 to be squeezed and contracted. At the same time, the rack 405 fixed on the L-shaped push rod 401 meshes with the gear 407 on the rotating rod 406, causing the rotating rod 406 to rotate. The baffle 408 at the bottom of the rotating rod 406 flips and releases the blockage of the installation groove 106. Since the filtering mechanism 2 moves in place towards the water inlet joint 102, the sundries filtered out on one side of the filtering mechanism 2 are moved by the movement of the filtering mechanism 2 and pushed to the position of the arc-shaped scraping blade 604;

[0050] At the same time, during the rotation of the rotating rod 406, the slider 602 slidably installed at the upper end of the rotating rod 406 moves towards the lower end of the rotating rod 406 under the guidance of the curve groove 601. At this time, the articulated rod 603 hinged on the slider 602 deflects, pushing the articulated arc-shaped scraping blade 604 to deflect and swing downward with the bottom of the arc-shaped scraping blade 604 as the center, scraping the sundries towards the position of the installation groove 106. At this time, the sundries gather towards the installation groove 106, and under the impact of the water flow, the garbage can enter the collection cylinder 5 through the installation groove 106 for collection.
