Technical Field

[0001] The utility model relates to the technical field of filter screen replacement, in particular to a drain outlet filter screen replacement mechanism. Background Art

[0002] Water conservancy projects are built to control, utilize and protect surface and underground water resources and the environment. Water conservancy is an integral part of river basin planning or regional water conservancy planning. The construction of a water conservancy project will have a great impact on the environment of its surrounding areas. It has both favorable aspects such as promoting benefits and eliminating harm, and unfavorable aspects such as flooding, inundation, immigration and relocation. Garbage will be generated during the water conservancy construction process, and this garbage needs to be filtered and cleaned. Generally, a filter screen is installed in the drainage pipe or flood outlet to filter the garbage through the filter screen.

[0020] The following is a further detailed description of a drain filter replacement mechanism of the present invention in conjunction with the accompanying drawings and embodiments of the present invention.

[0021] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0023] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0024] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0025] See also Figure 1-Figure 4 The utility model provides a technical solution: a drain outlet filter replacement mechanism, comprising: a drain pipe 1, a horizontal plate 2 is fixed on the inner wall of the outlet of the drain pipe 1, a mounting sleeve 3 is fixed on the horizontal plate 2, an extension rod 4 is provided on the inner side of the mounting sleeve 3, a return spring 5 is sleeved on the end of the extension rod 4 located in the mounting sleeve 3, a limiting cross bar 6 is installed on the end of the extension rod 4 located outside the mounting sleeve 3, a latch 7 is provided on the surface of the limiting cross bar 6, a filter frame 8 is provided in the outlet of the drain pipe 1, a filter screen 9 is provided in the filter frame 8, a notch 10 is opened on the filter frame 8, and a socket 11 is provided on the edge of the notch 10.

[0026] The horizontal plates 2 in this example are symmetrically distributed on the inner wall of the drain pipe 1, so that the horizontal plates 2 can cooperate with the limiting cross bars 6 to stably install the filter frame 8 and the filter screen 9.

[0027] The extension rod 4 in this example is a "T"-shaped structure, and the extension rod 4 and the mounting sleeve 3 form a telescopic structure. The two ends of the reset spring 5 are respectively pressed against one end of the extension rod 4 and the inner wall of the mounting sleeve 3, making it convenient to pull the extension rod 4 out of the mounting sleeve 3. When the extension rod 4 is no longer pulled, the reset spring 5 will push the extension rod 4 back into the mounting sleeve 3.

[0028] The extension rod 4 in this example is rotatably connected to the mounting sleeve 3, which facilitates the rotation of the limiting cross bar 6 on the mounting sleeve 3 through the extension rod 4, and is conducive to the limiting cross bar 6 being turned horizontally from a vertical state.

[0029] In this example, the limiting cross bar 6 is connected to the filter frame 8 through the notch 10 , which facilitates the limiting cross bar 6 to pass through the notch 10 and the filter frame 8 .

[0030] The latch 7 and the insertion hole 11 in this example correspond to each other. When the return spring 5 pushes the extension rod 4 to retract into the installation sleeve 3, the extension rod 4 can pull the limiting cross bar 6 to drive the latch 7 to be inserted into the insertion hole 11.

[0031] Working principle: According to Figure 1-Figure 4 When the filter screen 9 at the drain outlet position of the drain pipe 1 needs to be replaced, the limit cross bar 6 is first pulled away from the filter frame 8 until the pin 7 on the surface of the limit cross bar 6 is disconnected from the insertion hole 11, and then the limit cross bar 6 is turned to rotate. At this time, the limit cross bar 6 drives the extension rod 4 to rotate in the installation sleeve 3 until the limit cross bar 6 is aligned with the slot 10. At this time, the filter screen 9 together with the filter frame 8 can be taken out from the pipe outlet position of the drain pipe 1. When the new filter screen 9 together with the filter frame 8 is installed outside the cross plate 2, the limit cross bar 6 is turned to rotate horizontally, and the pulled limit cross bar 6 is released. At this time, the return spring 5 pushes the extension rod 4 to retract into the installation sleeve 3, and the extension rod 4 can pull the limit cross bar 6 to drive the pin 7 to be inserted into the insertion hole 11 until the pin 7 is aligned and stuck in the insertion hole 11. At this time, the filter screen 9 together with the filter frame 8 is restricted by the limit cross bar 6, and the installation is completed.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
