Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rainwater purification devices, in particular to a sponge city rainwater retention and purification device. BACKGROUND

[0002] The sponge city rainwater retention and purification device is a purification structure arranged at the water inlet of a rainwater collection pool, which specifically comprises a collection pipe arranged at a slightly lower position than the ground of an underground inlet and connected to a rainwater collection pool water inlet pipe, and a plurality of filter screens arranged in the collection pipe for filtering rainwater.

[0003] However, since the purification structure is arranged underground and the filter screen is provided with multiple layers, when maintenance personnel need to determine whether the filter screen needs to be replaced, the filter screen needs to be taken out one by one for judgment, which is very troublesome. CONTENT OF THE UTILITY MODEL

[0004] In view of the deficiencies in the prior art, the purpose of the present application is to provide a sponge city rainwater retention and purification device to solve the technical problem that it is very troublesome to determine whether the filter screen needs to be replaced in the prior art.

[0005] The above-mentioned purpose of the present application is achieved by the following technical solution: a sponge city rainwater retention and purification device, comprising a mounting shell, a collection pipe vertically slidingly mounted in the mounting shell, and a filter assembly mounted in the collection pipe, wherein one side of the collection pipe is provided with an opening penetrating through the collection pipe, and the upper end of the collection pipe is inserted with a blocking door extending into the opening.

[0006] Further, the filter assembly comprises a placing flange arranged on the opposite sides of the collection pipe, a filter frame abutting on the placing flanges on both sides, and a filter screen fixedly arranged in the filter frame, and the filter assembly is provided with multiple groups along the height direction of the collection pipe.

[0007] By adopting the technical scheme, when the purification device is installed, only the installation shell is fixed to the ground to make the collecting pipe butt joint with the water inlet pipe of the rainwater collecting pool, so that when the maintenance personnel need to maintain the filter screen and determine whether it needs to be replaced, the collecting pipe is only pulled to slide upward to make the collecting pipe protrude from the ground, then the maintenance personnel can slide the blocking door upward, so that the maintenance personnel can observe the state of the filter screen inside the collecting pipe, when the filter screen needs to be replaced, only the filter frame corresponding to the filter screen is pulled to make it separate from the placing flange, then the maintenance personnel only need to take a new filter frame with a filter screen, place it on the placing flange and push it into the collecting pipe, so that the maintenance personnel can observe, maintain and replace the filter screen more conveniently.

[0008] Further, the bottom end of the installation shell is provided with a control structure facilitating the maintenance personnel to slide the collecting pipe.

[0009] Further, the control structure comprises a control plate fixedly arranged at the bottom end inside the installation shell and a control screw rod penetrating through the side wall of the collecting pipe from top to bottom and rotationally connected with the control plate, and the control screw rod is threadedly connected with the collecting pipe.

[0010] By adopting the technical scheme, although the slidingly arranged collecting pipe makes the maintenance personnel observe, maintain and replace the filter screen more conveniently, the maintenance personnel need to hold the collecting pipe to prevent it from falling down after pulling it upward each time, which leads to that two maintenance personnel need to cooperate to maintain the filter screen, which is very wasteful of human resources, and the arrangement of the control structure solves the technical problem, when the maintenance personnel need to pull the collecting pipe upward, only the control screw rod is rotated to make the collecting pipe threadedly connected with the control screw rod ascend along the thread of the control screw rod, and when the collecting pipe protrudes from the ground, the rotation is stopped, because the collecting pipe cannot fall down due to the limitation of the control screw rod, so one maintenance personnel can complete the maintenance, thereby saving the use of human resources, and when the collecting pipe needs to be reset, only the control screw rod is rotated in the reverse direction.

[0011] Further, the bottom end of the outside of the blocking door is provided with a handle.

[0012] By adopting the technical scheme, the maintenance personnel can pull the blocking door upward more conveniently.

[0013] Further, the opening is provided with a limiting structure arranged outside the collecting pipe and used for preventing the blocking door from descending.

[0014] Further, the limiting structure comprises two fixed plates fixedly arranged on the outside of the collecting pipe in left and right opposition, a rotating shaft located between the two fixed plates and rotationally connected with the fixed plates and a bent hook fixedly connected with the rotating shaft.

[0015] Through adoption of the above technical scheme, although the setting of the plugging door makes it more convenient for the maintenance personnel to observe, maintain and replace the filter screen, the maintenance personnel needs to hold the plugging door all the time when replacing the filter frame, which is very inconvenient, and the setting of the limiting structure solves this technical problem, through the setting of the limiting structure, after the maintenance personnel pulls the plugging door to rise, the plugging door is hooked by the handle by rotating the hook, so that the plugging door will not descend, and the maintenance personnel can conveniently replace the filter frame.

[0016] Further, the mounting shell upper end is provided with a shielding plate for blocking the interval between the mounting shell and the collecting pipe, and the shielding plate is provided with a screw which is screwed to the mounting shell through the shielding plate.

[0017] Through adoption of the above technical scheme, rainwater is prevented from flowing into the rainwater collection pool inlet pipe from the interval between the mounting shell and the collecting pipe.

[0018] In summary, the present application has at least one of the following beneficial technical effects:

[0019] Through the setting of the mounting shell and the filter assembly, when the maintenance personnel needs to maintain and replace the filter screen, the maintenance personnel only needs to pull the collecting pipe to slide upward, so that the collecting pipe protrudes from the ground, and then the maintenance personnel can slide the plugging door upward, so that the maintenance personnel can observe the state of the filter screen inside the collecting pipe, when the filter screen needs to be replaced, the maintenance personnel only needs to pull the filter frame corresponding to the filter screen to make it separate from the placement flange, and then the maintenance personnel only needs to take a new filter frame with a filter screen, place it on the placement flange and push it into the collecting pipe, so that the maintenance personnel can observe, maintain and replace the filter screen more conveniently.

DETAILED DESCRIPTION

[0023] The present application is further described in detail below with reference to the accompanying drawings.

[0024] Embodiment, refer to Figure 1 , Figure 2The utility model provides a kind of sponge city rainwater retention purification device, including one installation shell 1, one located inside installation shell 1 can slide along the vertical direction inside installation shell 1 collection pipe 10 and filter assembly 2 being arranged in collection pipe 10 inside.Collection pipe 10 side is provided with an opening 11 passing through whole pipe body.In the upper end of collection pipe 10, there is a blocking door 12 inserted in collection pipe 10, it can be inserted into opening 11 and block opening 11.

[0025] Filter assembly 2 is jointly formed by the placement flange 20 being arranged on the opposite sides inside collection pipe 10, the filter frame 21 being butted on two placement flanges 20 on two sides, and the filter screen 22 being fixedly connected inside filter frame 21.It is worth mentioning that such filter assembly 2 is provided with multiple groups along the height direction of collection pipe 10 to cope with different rainwater purification needs.

[0026] When installing such purification device, it is exceptionally simple to operate.Only need to be fixed firmly underground installation shell 1, ensure that collection pipe 10 can be accurately docked to the water inlet pipe of rainwater collection pool, and the whole device is declared installation complete.In this way, when maintenance personnel need to carry out routine inspection to filter screen 22 or judge whether it needs to be replaced, they only need to easily pull collection pipe 10, make it slide along installation shell 1 upwards, until part or all of collection pipe 10 protrude from ground surface.At this time, maintenance personnel can further operate, slide blocking door 12 upwards, open opening 11 of collection pipe 10, so that the actual state of filter screen 22 inside collection pipe 10 can be clearly observed.

[0027] Once it is found that filter screen 22 needs to be replaced due to damage or blockage, maintenance personnel only need to simply pull filter frame 21 corresponding to the position of filter screen 22, make it easily separate from placement flange 20.Subsequently, they can place prepared new filter frame 21 on placement flange 20, and gently push it, make it extend into collection pipe 10 stably.Such design undoubtedly greatly simplifies the work flow of maintenance personnel observation, maintenance and replacement of filter screen 22, so that they can more efficiently and conveniently complete various tasks.

[0028] Although the sliding collection tube 10 makes it more convenient for maintenance personnel to observe, repair, and replace the filter screen 22, each time the collection tube 10 is pulled up, the maintenance personnel need to hold the collection tube 10 to prevent it from falling. This means that it takes two maintenance personnel to repair the filter screen 22, which is a waste of human resources. To solve this technical problem, this embodiment has a control structure 3 at the bottom of the mounting housing 1 to facilitate the sliding of the collection tube 10 by maintenance personnel. The control structure 3 includes a control plate 30 fixedly installed at the bottom of the mounting housing 1 and a control plate that passes through the collection tube 10 from top to bottom. The control screw 31 of the control plate 30 is connected to the wall and rotates. The control screw 31 is threadedly connected to the collection pipe 10. When the maintenance personnel need to move the collection pipe 10 upward, they only need to rotate the control screw 31 so that the collection pipe 10 threadedly connected to the control screw 31 rises along the thread of the control screw 31. When the collection pipe 10 protrudes above the ground, the rotation stops. Because of the restriction of the control screw 31, the collection pipe 10 will not fall. In this way, the maintenance personnel can complete the maintenance, thereby saving manpower. When the collection pipe 10 needs to be reset, the control screw 31 can be rotated in the opposite direction.

[0029] In this embodiment, a handle 13 is provided at the bottom outer side of the sealing door 12 so that maintenance personnel can pull the sealing door 12 up.

[0030] Although the sealing door 12 makes it easier for maintenance personnel to observe, repair, and replace the filter screen 22, it is very inconvenient for them to hold the sealing door 12 while replacing the filter frame 21. To solve this technical problem, this embodiment provides a limiting structure 4 above the opening 11, installed on the outside of the collection pipe 10, to prevent the sealing door 12 from falling. The limiting structure 4 includes two fixed plates 40 fixedly arranged on the outside of the collection pipe 10, a rotating shaft 41 located between the two fixed plates 40 and rotatably connected to the fixed plates 40, and a hook 42 fixedly connected to the rotating shaft 41. With the limiting structure 4, after the maintenance personnel pull the sealing door 12 up, they can hook the handle 13 by rotating the hook 42, so that the sealing door 12 will not fall, and the maintenance personnel can easily replace the filter frame 21.

[0031] In this embodiment, the upper end of the mounting housing 1 is provided with a baffle plate 14 for blocking the gap between the mounting housing 1 and the collection pipe 10. The baffle plate 14 is provided with a screw 15, which passes through the baffle plate 14 and is threaded to the mounting housing 1 to prevent rainwater from flowing into the rainwater collection tank inlet pipe from the gap between the mounting housing 1 and the collection pipe 10.

[0032] Specific implementation process: When installing the purification device, simply fix the installation housing 1 underground so that the collection pipe 10 connects to the rainwater collection tank inlet pipe. Then, install the baffle 14 on the installation housing 1 using screws 15. When maintenance personnel need to inspect whether the filter screen 22 needs to be replaced, they must first remove the baffle 14, and then rotate the control screw 31 so that the collection pipe 10 connected to the control screw 31 rises along the thread of the control screw 31. When the collection pipe 10 protrudes above the ground, stop rotating, then pull the sealing door 12 to rise, and then rotate the hook 42 to hook the handle 13. In this way, maintenance personnel can observe the status of the filter screen 22 inside the collection pipe 10. When encountering a filter screen 22 that needs to be replaced, simply pull the filter frame 21 corresponding to the filter screen 22 to disengage it from the placement flange 20. Then, maintenance personnel only need to take the new filter frame 21 with the filter screen 22, place it on the placement flange 20, and push it into the collection pipe 10.

[0033] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
