Description

Technical Field

[0001] This application relates to the technical field of rainwater harvesting and utilization, and in particular to a sewage interception basket device. Background Technology

[0002] A storm drain basket is a basket-shaped container typically installed at storm drain manholes, storm drain hoppers, or the inlet of drainage pipes. Its main function is to intercept, collect, and temporarily store larger solid impurities, such as leaves and twigs, carried in rainwater or surface runoff.

[0003] The intercepting basket device includes a basket body and a filter plate installed on one side of the top of the basket body. The filter plate is arranged at the outlet to intercept larger impurities, and the basket body is used to collect the intercepted impurities. In rainwater harvesting systems, the basket body is usually placed at the inlet of the drainage pipe to perform preliminary filtration of debris such as leaves and branches in the rainwater.

[0004] Regarding the aforementioned technologies, rainwater harvesting systems are typically installed underground at considerable depths. They usually have inspection wells on the surface. When cleaning impurities from the intercepting basket device, the basket body is lifted by workers and removed from the inspection well. However, during the removal process, the basket body may shake, impact the well wall, and rub against it, which can easily cause damage and reduce its service life. Utility Model Content

[0005] In order to reliably remove the main body of the hanging basket from the inspection well, this application provides a sewage interception hanging basket device.

[0006] The sewage interception basket device provided in this application adopts the following technical solution: A sewage interception basket device includes a support base installed at the bottom of a rainwater collection well, a guide column installed at the top of the support base, and a basket body slidably installed on the guide column. The basket body includes a net basket, a filter baffle installed at the top of the net basket near the outlet, and a lifting hook installed at the top of the net basket. The net basket includes a support top ring and a filter net installed at the bottom of the support top ring. The inner side of the support top ring has a downward-curved edge, and the downward-curved edge has a through-hole for installation. The top of the filter net is provided with an installation sleeve that mates with the through-hole. The support top ring has a guide through-hole that mates with the guide column, and the lower part of the guide column has a positioning protrusion that abuts against the support top ring.

[0007] By adopting the above technical solution, the support base is installed at the bottom of the rainwater collection well, providing stable support for the entire device. The guide column is installed on top of the support base, engaging with the guide through-hole of the support top ring to guide the sliding of the basket body. The positioning protrusion abuts against the support top ring, limiting the downward movement of the basket body and thus positioning it. The filter basket of the net basket is installed at the bottom of the support top ring through an mounting sleeve that engages with the mounting through-hole on the lower flange of the support top ring, intercepting and collecting debris from the water. A filter baffle is installed on the top of the net basket near the outlet, further filtering larger impurities in the water; the intercepted impurities fall into the filter basket and are collected. A lifting hook is installed on the top of the support top ring for easy lifting of the net basket.

[0008] Optionally, the guide column is provided with a ball-head spring plunger, which is arranged on the upper side of the positioning protrusion, and the support top ring has a snap-fit ​​groove on the inner side wall of the guide through hole that cooperates with the ball-head spring plunger.

[0009] By adopting the above technical solution, the guide column is equipped with a ball-head spring plunger, and the inner wall of the guide through hole of the support top ring is opened with a snap-fit ​​groove to cooperate with it. When the bottom of the support top ring abuts against the positioning protrusion, the ball-head spring plunger can abut against the top of the support top ring, reducing the probability of the basket body floating due to water flow impact or water level changes, ensuring the stability of the basket body in the water, and not affecting the filtration effect.

[0010] Optionally, a sliding gap is formed between the supporting top ring and the side wall of the rainwater collection well for the net basket to be raised and lowered.

[0011] By adopting the above technical solution, a sliding gap is formed between the top support ring and the side wall of the rainwater collection well, which allows the main body of the hanging basket to move smoothly up and down in the rainwater collection well, reducing the probability of interference between the hanging basket and the well wall during the lifting process, and ensuring the normal use and maintenance of the sewage interception hanging basket device.

[0012] Optionally, the number of guide columns is at least two and they are arranged circumferentially on the top of the support base, and the guide through holes are arranged in a one-to-one correspondence with the guide columns.

[0013] By adopting the above technical solution, the combination of multiple circumferentially arranged guide columns and corresponding guide through holes can make the sliding of the main body of the hanging basket on the guide columns more stable, ensure the smooth lifting and lowering of the main body of the hanging basket, and improve the overall stability and reliability of the device.

[0014] Optionally, the lifting hook includes a lifting hook and an installation rod connected to the lower end of the lifting hook; the top of the support ring is provided with a cross support frame, the center of the cross support frame is provided with an installation support column for installing the installation rod, the top of the installation support column is provided with an installation groove for inserting the installation rod, and the installation column is provided with a locking bolt that penetrates the side wall of the installation groove and is used to lock the installation rod.

[0015] By adopting the above technical solution, the lifting hook consists of a lifting hook and an installation rod. The top of the support ring is equipped with a cross support frame and an installation column. The installation column has an installation groove for the installation rod to be inserted and is locked by locking bolts, thus realizing a stable connection between the lifting hook and the support ring. This facilitates the lifting operation of the main body of the basket and ensures the stability of the main body of the basket during the lifting process.

[0016] Optionally, the end of the lifting hook is provided with a limiting protrusion on the side facing the mounting column to prevent the lifting rod from detaching.

[0017] By adopting the above technical solution, a limiting protrusion is set at the end of the lifting hook, which can restrict the lifting rod from coming out and improve the stability and safety of the main body of the hanging basket during the lifting process.

[0018] Optionally, the top of the lifting hook is provided with an abutting protrusion, and the abutting protrusion has an abutting groove for inserting a push rod.

[0019] By adopting the above technical solution, the top of the lifting hook is provided with an abutting protrusion and the abutting protrusion is provided with an abutting groove, which can provide a stable abutting structure when the push rod pushes the lifting hook downward, and facilitate the installation of the main body of the hanging basket.

[0020] Optionally, the bottom of the filter baffle has an outwardly flanged edge that mates with the supporting top ring.

[0021] By adopting the above technical solution, the outward flange at the bottom of the filter baffle is installed in conjunction with the support top ring, making the installation of the filter baffle more stable and enabling it to better perform its filtering function and ensure the interception effect of the sewage basket device. This installation method can reduce the probability of friction between the filter baffle and the well wall when the basket body is lifted upward.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. A sewage interception basket device, which can effectively intercept large impurities in rainwater by setting a net basket and a filter baffle, reducing the amount of impurities entering the water outlet pipe; the guide column provides stable guidance for the lifting and lowering of the basket body; 2. By installing ball-head spring plungers on the guide columns, the probability of the main body of the hanging basket floating due to water flow impact or water level changes can be reduced, ensuring the stability of the main body of the hanging basket in the water; 3. The installation of lifting hooks facilitates the lifting of the main body of the hanging basket from the rainwater collection well for cleaning. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a wastewater intercepting basket device. (Refer to...) Figure 1 The intercepting basket device includes a support base 1 installed at the bottom of the rainwater collection well, a guide column 2 vertically installed on the top of the support base 1, and a basket body 3 slidably installed on the guide column 2. This device is adaptable to rainwater collection wells of various cross-sectional shapes, such as circular or rectangular. In this embodiment, a rectangular collection well is used as an example. The support base 1 adopts a rectangular structure, matching the contour of the well bottom, and is firmly integrated with the well foundation through pre-embedding. The guide column 2 is vertically fixed to the top of the support base 1 by welding. Both the support base 1 and the guide column 2 are made of metal.

[0031] Reference Figure 1To ensure the stable lifting and lowering of the hanging basket body 3, the number of guide columns 2 is at least two and arranged circumferentially on the top of the support base 1. In this embodiment, the number of guide columns 2 is four, and the four guide columns 2 are respectively arranged at the four corners of the top of the support base 1.

[0032] Reference Figure 1 The main body 3 of the hanging basket includes a net basket 31, a filter baffle 32 installed on the top of the net basket 31 near the outlet, and a lifting hook 33 installed on the top of the net basket 31. The net basket 31 includes a supporting top ring 311 and a filter net 312 installed at the bottom of the supporting top ring 311. The supporting top ring 311 is made of metal with a thickness of no more than one centimeter. Guide holes 3111 are provided at the four corners of the supporting top ring 311 to cooperate with the guide posts 2. A sliding gap is formed between the supporting top ring 311 and the side wall of the rainwater collection well for the net basket 31 to rise and fall.

[0033] Reference Figure 2 The inner side of the supporting top ring 311 has a downwardly extending flange 3112, and the flange 3112 has a through-hole 3113 extending through the side. The top of the filter bag 312 is provided with a mounting sleeve 3121 that mates with the mounting through-hole 3113. In this embodiment, the supporting top ring 311 has a rectangular cross-sectional shape, and the four sides of its flange 3112 are provided with mounting through holes 3113 to achieve uniform circumferential installation and fixation of the filter bag 312.

[0034] Reference Figure 2 Each of the four guide columns 2 has a positioning protrusion 21 at its lower part that abuts against the support top ring 311. In this embodiment, the positioning protrusion 21 is integrally formed on the guide column 2. The positioning protrusion 21 is located below the water inlet and restricts the downward movement of the basket body 3, thereby positioning the basket body 3.

[0035] Reference Figure 3 and Figure 4 The guide column 2 is also equipped with a ball-head spring plunger 22, which is arranged on the upper side of the positioning protrusion 21. The support top ring 311 has a snap-fit ​​groove 3114 on the inner wall of the guide through hole 3111 that mates with the ball-head spring plunger 22. The ball-head spring plunger 22 includes a plunger housing 221, a plunger ball 222 installed inside the plunger housing 221, and a plunger spring 223 installed inside the plunger housing 221 to support the plunger ball 222. When the bottom of the support top ring 311 abuts against the positioning protrusion 21, the top of the support top ring 311 abuts against the bottom of the ball-head spring plunger 22, and the ball-head spring plunger 22 prevents the basket body 3 from floating due to water flow impact or water level changes.

[0036] Reference Figure 5The lifting hook 33 includes a lifting hook 331 and a mounting rod 332 connected to the lower end of the lifting hook 331. A cross support frame 3115 is provided on the top of the supporting top ring 311, and a vertically upward mounting post 3116 for mounting the mounting rod 332 is provided at the central intersection of the cross support frame 3115. In this embodiment, the cross support frame 3115 is installed on the top of the supporting top ring 311 by welding, and the mounting post 3116 is also installed on the cross support frame 3115 at the central intersection by welding.

[0037] Reference Figure 5 The mounting support 3116 has a mounting groove 3117 at its top that matches the diameter of the mounting rod 332. A threaded hole communicating with the mounting groove 3117 is formed on the side wall of the mounting support 3116, where a locking bolt is fitted. The lower part of the mounting rod 332 has a through-side groove that mates with the locking bolt. When the mounting rod 332 is inserted into the mounting groove 3117, the locking bolt is tightened so that its end is embedded in the groove, forming a reliable axial and circumferential double fixation. To prevent the lifting rod from detaching, a limiting protrusion 3311 is provided on the side of the lifting hook 331 facing the mounting support 3116 to limit the detachment of the lifting rod. In this embodiment, the limiting protrusion 3311 is integrally formed on the lifting hook 331.

In this embodiment, the cross-section of the abutment groove 3313 is arc-shaped. When the basket body 3 is installed into the well, the push rod will abut against the abutment groove 3313 of the abutment protrusion 3312, pushing the basket body 3 to slide down stably.

[0039] Reference Figure 2 The filter baffle 32 has an outward flange 321 at its bottom that mates with the support top ring 311. The outward flange 321 extends horizontally outward along the bottom edge of the filter baffle 32, and its shape matches the top contour of the support top ring 311. During installation, the outward flange 321 fits tightly against the top surface of the support top ring 311, and a secure connection is achieved through bolts.

[0040] Combination Figures 1 to 5The implementation principle of the intercepting basket device in this application embodiment is as follows: the guide column 2 provides guidance for the sliding of the net basket 31, enabling the net basket 31 to move up and down along the guide column 2. When rainwater flows into the rainwater collection well, the net basket 31 and the filter baffle 32 intercept larger impurities in the rainwater and collect them inside the net basket 31. When it is necessary to clean the impurities, the net basket 31 is removed from the rainwater collection well by the lifting hook 33, and after cleaning, it is put back into its original position along the guide column 2.

[0041] The above are all 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.
