Description

Technical Field

[0001] This application relates to the field of manhole inspection well technology, and more specifically, to a plastic inspection well with a built-in trap basket. Background Technology

[0002] Plastic inspection wells with built-in trap baskets are a modern drainage system component, primarily used for inspection and maintenance of urban drainage networks. They effectively intercept debris in sewage, preventing pipe blockage.

[0003] Patent publication number CN222183614U discloses a sealed inspection well for a sewage interception system in a flood drainage channel. The well includes a well body positioned below the bottom of the channel. A flow channel is formed on the inner wall of the bottom of the well body, with pipes installed at both ends of the flow channel, extending out of the well body at both ends. Pipe holes are formed on both sides of the well body, and waterproof sleeves are installed within these holes. Flexible material is filled between the waterproof sleeves and the pipes. A well seat mounting groove is formed at the top of the well body, and a well seat is installed within the groove. A well cover is installed on the well seat. This disclosed sealed inspection well, positioned below the bottom of the flood drainage channel, utilizes key measures such as a reinforced concrete well body, waterproof sleeves, and a novel sealed well cover to construct a sewage sealed inspection well with good sealing performance, simple structure, safety, reliability, and convenient maintenance.

[0004] The aforementioned application document states that pipe holes are opened on both sides of the well body, and waterproof sleeves are installed inside the pipe holes. Flexible material components are filled between the waterproof sleeves and the pipes. However, this method cannot clean up the intercepted garbage, which may cause the pipes to become blocked and affect the subsequent interception effect. Therefore, it needs to be improved. Utility Model Content

[0005] To overcome the above-mentioned defects, embodiments of this application provide a plastic inspection well with a built-in interception basket, which solves the technical problem in the prior art that the pipe may become blocked, affecting the subsequent interception effect.

[0006] According to one aspect, at least one embodiment of this application provides a plastic inspection well with a built-in intercepting basket, comprising: an upper inspection well, a lower inspection well fixedly connected to the bottom of the upper inspection well, a well cover fixedly connected inside the upper inspection well, a water inlet on the circumferential surface of the upper inspection well, a water outlet on the circumferential surface of the lower inspection well, and a intercepting device disposed inside the upper inspection well; the intercepting device includes an intercepting cylinder, the intercepting cylinder being slidably connected to the inner wall of the lower inspection well, a first filter screen fixedly connected inside the intercepting cylinder, a second filter screen fixedly connected inside the intercepting cylinder, a sliding strip fixedly connected inside the upper inspection well, a sliding groove on the back side of the sliding strip, a slider slidably connected inside the sliding groove, and a limit block fixedly connected to the circumferential surface of the intercepting cylinder.

[0007] For example, in a plastic inspection well with a built-in intercepting basket provided in at least one embodiment of this application, a spring is fixedly connected inside the upper inspection well, and the end of the spring away from the upper inspection well is fixedly connected to the bottom of the slider. The function of the spring is to reduce the impact of the intercepting cylinder on the upper or lower inspection well when the sewage is collected and intercepted.

[0008] The bottom of the intercepting cylinder is fixedly connected to a telescopic rod, and the bottom of the telescopic rod is fixedly connected to a sludge settling box. The function of the sludge settling box is to store the sludge that settles in the sewage.

[0009] The circumferential surface of the intercepting cylinder is fixedly connected to a lifting ring, which is used to pull the intercepting cylinder out of the inspection well for cleaning.

[0010] The bottom of the first filter screen is located above the second filter screen, and the filter opening of the first filter screen is larger than that of the second filter screen. The number of each of the sliding strip, sliding groove, sliding block, limiting block, elastic spring, and telescopic rod is set to two, and they are symmetrical to each other along the vertical central axis of the intercepting cylinder. The purpose of the first filter screen being located above the second filter screen and the filter opening of the first filter screen being larger than that of the second filter screen is to allow for multiple filtrations. The purpose of setting the number of each of the sliding strip, sliding groove, sliding block, limiting block, elastic spring, and telescopic rod to two, and symmetrical to each other along the vertical central axis of the intercepting cylinder, is to better mitigate the impact on the upper or lower inspection well.

[0011] According to another aspect, at least one embodiment of this application also provides a plastic inspection well with a built-in intercepting basket, comprising: a cleaning device disposed inside the intercepting cylinder, the cleaning device including a slot, the slot being opened at the top of a first filter screen, a collection frame fixedly connected inside the slot, a water outlet being opened at the bottom of the collection frame, a rotating rod rotatably connected inside the collection frame, the circumferential surface of the rotating rod penetrating the well cover, the circumferential surface of the rotating rod being rotatably connected to the inner wall of the well cover, and a push plate fixedly connected to the circumferential surface of the rotating rod, the function of the push plate being to push larger debris on the first filter screen into the collection frame.

[0012] For example, in a plastic inspection well with a built-in intercepting basket provided in at least one embodiment of this application, the following is also included: a slide rail is provided on the top of the intercepting cylinder, a slide rod is slidably connected inside the slide rail, a fixing rod is fixedly connected to the circumferential surface of the slide rod, and the front side of the fixing rod is fixedly connected to the circumferential surface of the rotating rod. The function of the slide rail and the slide rod is to support and limit the rotating rod.

[0013] A handle is fixedly connected to the top of the rotating rod, and a through hole is provided on the top of the manhole cover. The purpose of the through hole is to allow the handle to pass through and lift the manhole cover.

[0014] A torsion spring is fixedly connected to the circumferential surface of the rotating rod. The end of the torsion spring away from the rotating rod is fixedly connected to the side of the collection frame. The function of the torsion spring is to allow the rotating rod to return to its original position when it is not rotating.

[0015] The bottom of the handle is located above the through hole, and the top of the collection frame is located below the push plate. The purpose of the bottom of the handle being above the through hole is to prevent the handle from blocking the manhole cover when it needs to be lifted. The purpose of the top of the collection frame being below the push plate is to push the garbage on the first filter screen into the collection frame when the push plate rotates.

[0016] The beneficial effects of the embodiments of this application are as follows:

[0017] 1. In this application, by setting up a sewage interception device, when sewage enters the sewage interception cylinder, it will pass through the first filter screen to filter out larger impurities in the sewage, and then pass through the second filter screen for further filtration, so as to prevent larger impurities from clogging the pipe. When the sewage inflow exceeds the outlet, the filtered sewage will be discharged from the sludge box through the outlet. At this time, the sludge deposited in the sludge box will remain in the sludge box.

[0018] 2. In this application, the cleaning device achieves the function of rotating the handle. When the handle is rotated, it drives the rotating rod to rotate. When the rotating rod rotates, it drives the fixed rod to rotate. When the fixed rod rotates, it drives the sliding rod to rotate in the slide rail, so that the rotating rod can be supported and limited. When the rotating rod rotates, it also drives the push plate to rotate, so that when the push plate rotates, it can push the impurities filtered out of the first filter screen into the collection box, thereby preventing impurities from clogging the first filter screen and slowing down the filtration effect.

[0030] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-5 As shown, a plastic inspection well with a built-in intercepting basket is provided in one embodiment of this application, including: an upper inspection well 1, a lower inspection well 2 fixedly connected to the bottom of the upper inspection well 1, a well cover 3 fixedly connected inside the upper inspection well 1, a water inlet 4 opened on the circumferential surface of the upper inspection well 1, a water outlet 5 opened on the circumferential surface of the lower inspection well 2, and a intercepting device 6 provided inside the upper inspection well 1; the intercepting device 6 includes an intercepting cylinder 61, the intercepting cylinder 61 is slidably connected to the inner wall of the lower inspection well 2, a first filter screen 62 is fixedly connected inside the intercepting cylinder 61, a second filter screen 63 is fixedly connected inside the intercepting cylinder 61, a sliding strip 64 is fixedly connected inside the upper inspection well 1, a sliding groove 65 is opened on the back side of the sliding strip 64, a slider 66 is slidably connected inside the sliding groove 65, and a limit block 67 is fixedly connected to the circumferential surface of the intercepting cylinder 61.

[0033] In some examples, an elastic spring 68 is fixedly connected inside the upper inspection well 1. The end of the elastic spring 68 away from the upper inspection well 1 is fixedly connected to the bottom of the slider 66. The function of the elastic spring 68 is to reduce the impact of the sewage intercepting cylinder 61 on the upper inspection well 1 or the lower inspection well 2 when the sewage is collected and the intercepting cylinder 61 is used.

[0034] The bottom of the intercepting cylinder 61 is fixedly connected to a telescopic rod 69, and the bottom of the telescopic rod 69 is fixedly connected to a sludge settling box 610. The function of the sludge settling box 610 is to store the sludge that settles in the sewage.

[0035] A lifting ring 611 is fixedly connected to the circumferential surface of the intercepting cylinder 61. The function of the lifting ring 611 is to pull the intercepting cylinder 61 out of the upper inspection well 1 for cleaning.

[0036] The bottom of the first filter screen 62 is located above the second filter screen 63. The filter opening of the first filter screen 62 is larger than the filter opening of the second filter screen 63. The number of sliders 64, grooves 65, sliders 66, limit blocks 67, springs 68, and telescopic rods 69 are each set to two, and they are symmetrical to each other along the vertical central axis of the intercepting cylinder 61. The purpose of the first filter screen 62 being located above the second filter screen 63 and the filter opening of the first filter screen 62 being larger than the filter opening of the second filter screen 63 is to allow for multiple filtrations. The purpose of the sliders 64, grooves 65, sliders 66, limit blocks 67, springs 68, and telescopic rods 69 being set to two, and being symmetrical to each other along the vertical central axis of the intercepting cylinder 61, is to better mitigate the impact on the upper inspection well 1 or the lower inspection well 2.

[0037] For example, such as Figures 1-5 As shown, firstly, when the inspection well needs to be used, the interceptor device 6 can be used to filter impurities in the sewage to prevent them from clogging the pipe. By connecting the sewage inlet pipe to the inlet 4, the sewage will flow into the interceptor cylinder 61 through the inlet 4. When the sewage enters the interceptor cylinder 61, it will pass through the first filter screen 62 to filter larger impurities, and then through the second filter screen 63 for further filtration to prevent larger impurities from clogging the pipe. After the sewage is filtered, it will enter the sedimentation box 610 in the lower inspection well 2. When the sewage inflow exceeds the outlet... At 5 o'clock, the filtered sewage will be discharged into the sedimentation box 610 through the outlet 5. The sludge deposited in the sedimentation box 610 will remain in the sedimentation box 610. When the sewage enters the intercepting cylinder 61, it will impact the intercepting cylinder 61. When the intercepting cylinder 61 is impacted, it will move downward. When the intercepting cylinder 61 moves downward, it will press the spring spring 68 through the slider 66 to move downward, thereby reducing the impact of the intercepting cylinder 61 on the upper inspection well 1 and the lower inspection well 2 after being impacted, thus increasing the service life of the intercepting cylinder 61, the upper inspection well 1 and the lower inspection well 2.

[0038] like Figures 1-5As shown, this application illustrates a plastic inspection well with a built-in intercepting basket in another embodiment. The intercepting cylinder 61 is equipped with a cleaning device 7, which includes a slot 71. The slot 71 is located at the top of the first filter screen 62. A collection frame 72 is fixedly connected inside the slot 71. A water outlet 73 is provided at the bottom of the collection frame 72. A rotating rod 74 is rotatably connected inside the collection frame 72. The circumferential surface of the rotating rod 74 penetrates the well cover 3 and is rotatably connected to the inner wall of the well cover 3. A push plate 75 is fixedly connected to the circumferential surface of the rotating rod 74. The function of the push plate 75 is to push larger debris on the first filter screen 62 into the collection frame 72.

[0039] In some examples, the top of the intercepting cylinder 61 is provided with a slide rail 76, and a slide rod 77 is slidably connected inside the slide rail 76. A fixing rod 78 is fixedly connected to the circumferential surface of the slide rod 77. The front side of the fixing rod 78 is fixedly connected to the circumferential surface of the rotating rod 74. The function of the slide rail 76 and the slide rod 77 is to support and limit the rotating rod 74.

[0040] A handle 79 is fixedly connected to the top of the rotating rod 74, and a through hole 710 is opened on the top of the manhole cover 3. The through hole 710 is used to allow the handle 79 to pass through and lift the manhole cover 3.

[0041] A torsion spring 711 is fixedly connected to the circumferential surface of the rotating rod 74. The end of the torsion spring 711 away from the rotating rod 74 is fixedly connected to the side of the collection frame 72. The function of the torsion spring 711 is to allow the rotating rod 74 to be reset when it is not rotated.

[0042] The bottom of the handle 79 is located above the through hole 710, and the top of the collection frame 72 is located below the push plate 75. The purpose of the bottom of the handle 79 being located above the through hole 710 is to prevent the handle 79 from blocking the manhole cover 3 when it is necessary to lift the manhole cover 3. The purpose of the top of the collection frame 72 being located below the push plate 75 is to push the garbage on the first filter screen 62 into the collection frame 72 when the push plate 75 is rotated.

[0043] For example, such as Figures 1-5 As shown, when using this device to intercept sewage, the cleaning device 7 can be used to clean the impurities filtered out of the first filter screen 62, preventing impurities from clogging the filter port of the first filter screen 62 and slowing down the filtration effect. By turning the handle 79, the rotating rod 74 will rotate, which in turn will drive the fixed rod 78 to rotate. When the fixed rod 78 rotates, the sliding rod 77 will rotate within the slide rail 76, thus supporting and limiting the rotating rod 74. When the rotating rod 74 rotates, it will also drive the push plate 75 to rotate, so that when the push plate 75 rotates, it can push the impurities filtered out of the first filter screen 62 into the collection frame 72, thereby preventing impurities from clogging the first filter screen 62 and slowing down the filtration effect.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application, and all such modifications and substitutions should be covered within the scope of the claims of this application.
