[0002] In sewage treatment, it is often necessary to filter sewage. Figure 1 The schematic diagram of the structure of a common filtering device mainly includes a filter chamber a1, a filter plate detachably installed in the filter chamber, a water inlet pipe connected to the filter chamber between the filter plate and the bottom of the filter chamber, and a drain valve installed at the bottom of the filter chamber. The drain valve includes a section of a water outlet pipe connected to the bottom of the filter chamber by a flange. The inner wall of the water outlet pipe has a plurality of annular grooves for installing a sealing ring. A plug with a lifting ring is inserted from the bottom of the filter chamber to the outside into the water outlet pipe and passes through the sealing ring to squeeze and contact with it to achieve sealing. After the filtering device has been used for a period of time, it needs to be cleaned. Currently, the cleaning is mostly done by manual brushing. Although no professional tools are required and the cleaning tool cost is not too high, it is time-consuming and labor-intensive. It is extremely inconvenient, especially for the inner wall and the water outlet pipe of the filtering device that need to be cleaned frequently. In particular, the water outlet pipe is extremely difficult to clean due to the presence of the sealing groove. If the cleaning is not thorough and the sealing ring is improperly installed, it will directly lead to leakage of the filtering device. Summary of the invention

[0003] The purpose of the present invention is to solve the above technical problems and provide a device for cleaning the inner wall of a sewage filtering device, which effectively solves the technical problem of inconvenience in cleaning the filtering device in the prior art.

[0004] The technical solution of the present invention is as follows: A device for cleaning the inner wall of a sewage filtering device comprises a brush head for scrubbing, a moving device, an elastic driving component, and a clamping assembly for clamping and fixing a water outlet pipe, wherein

[0005] The moving device comprises a moving shaft that can move up and down and a transmission member connected to the moving shaft, wherein the brush head that matches the shape of the inner cavity of the filter bin is installed at the bottom end of the moving shaft, so that the inner wall of the filter bin can be scrubbed when the moving shaft moves up and down; the transmission member can move up and down with the moving shaft, and a wavy undulating portion is arranged on one side surface of the transmission member extending in the vertical direction;

[0006] An elastic driving component comprises a supporting plate, an elastic plate, a contact plate and a driving rod which are connected end to end in sequence, wherein only the elastic plate is elastic and is in an "n" shape, the supporting plate is fixedly arranged, the elastic plate is located above the brush head and its opening is arranged toward the side where the moving shaft is located, the contact plate is in a hook-shaped structure and the outer surface of its hook portion is always in smooth contact with the undulating portion when the transmission member moves up and down, the free end of the contact plate passes through the supporting plate toward the side away from the moving shaft and is hinged to the driving rod, a scrubbing head is installed on the driving rod, and the scrubbing head can extend into the water outlet pipe and fill the water outlet pipe to scrub it.

[0007] The beneficial effects of the present invention are as follows: the present invention drives the brush head to clean the inner wall of the filter bin by moving the movable shaft up and down, and the elastic action of the "n"-shaped elastic plate in the elastic driving component cooperates with the contact plate and the undulating part on the surface of the transmission component to make the contact plate perform a shaking motion, thereby driving the driving rod to shake and carry the scrubbing head hinged thereto to quickly and thoroughly clean the inner wall of the water outlet pipe, avoiding the inconvenience of still scrubbing, saving time, and making the cleaning more automated and clean, and quickly cleaning the inner wall of the filter bin and the inner wall of the water outlet pipe at the same time.

DETAILED DESCRIPTION

[0014] The following is a description of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0016] like Figure 2 As shown, this embodiment provides a device for cleaning the inner wall of a sewage filtration device, including a brush head 5 for scrubbing, a moving device, an elastic driving component, and a clamping assembly 11 for clamping and fixing a water outlet pipe. Among them: the moving device includes a moving shaft 1 that can move up and down and a transmission member 2 connected to the moving shaft 1, and a brush head 5 for cleaning that is adapted to the shape of the inner cavity of the filter bin is installed at the bottom end of the moving shaft 1, so that the inner wall of the filter bin can be scrubbed when the moving shaft 1 moves up and down. The above-mentioned transmission member 2 can move up and down with the moving shaft 1, and a wavy undulating portion is arranged on one side surface of the transmission member 2 extending in the vertical direction. Elastic driving component, see Figure 2-3 , which includes a support plate 6, an elastic plate 7, a contact plate 8 and a driving rod 9 connected in sequence end to end, wherein only the elastic plate 7 is elastic and the elastic plate 7 is in an "n" shape to enhance the elastic restoring force, the support plate 6 is fixedly arranged, the elastic plate 7 is located above the brush head 5 and its opening is arranged toward the side where the moving shaft 1 is located, the contact plate 8 is a hook-shaped structure and the outer surface of the hook portion is always in smooth contact with the undulating portion when the transmission member 2 moves up and down, the free end of the contact plate 8 passes through the support plate 6 toward the side away from the moving shaft 1 and is hinged to the driving rod 9, and a scrubbing head 10 is installed on the driving rod 9, and the scrubbing head 10 can extend into the water outlet pipe and fill the water outlet pipe to scrub it. When in use, the movable shaft 1 moves up and down to scrub the inner wall of the filter bin below it, and the brush head 5 contacts and fits with the inner wall of the filter bin to quickly wipe and clean it; at the same time, when the movable shaft 1 moves up and down, the transmission member 2 also moves up and down accordingly, and the undulating part on the transmission member 2 has a wavy and uneven structure, so that the hook part of the above-mentioned contact plate 8 in contact with it also fluctuates along the undulating part, thereby causing the contact plate 8 to shake, and finally causing the scrubbing head 10 to wipe back and forth in the water pipe, and due to the swing of the driving rod 9, the wiping movement amplitude is larger. Compared with the scrubbing head 10 connected with only an axially movable piston rod, the scrubbing head 10 of this embodiment can wipe the inner wall of the water outlet pipe more fully, and is less likely to get stuck, and the cleaning is efficient and thorough, which is similar to the cleaning principle of a vibration wiping, with a simple structure and easy implementation, but good cleaning efficiency and effect.

[0017] As a specific implementation, see Figure 4-5The scrubbing head 10 of this embodiment includes a cylindrical scrubbing body 1001, which can be wedged with the inside of the water outlet pipe, and has a plurality of annular grooves arranged along the axial direction on the outer cylindrical surface of the scrubbing body 1001, and a circular elastic inflatable ring 1002 is embedded in the annular groove, and the elastic inflatable ring 1002 is exposed outside the cylindrical surface of the scrubbing body 1001, and the inflatable hose 12 connected with the elastic inflatable ring 1002 extends out of the scrubbing body 1001 along the axial direction of the scrubbing body 1001. When in use, a certain amount of compressed air is filled into the elastic inflatable ring 1002 through the hose, so that the collision of the elastic inflatable ring 1002 becomes larger, and the tightness of the elastic inflatable ring 1002 with the water outlet pipe can be adjusted, thereby improving the cleaning and wiping effect, especially more fully contacting with the sealing groove on the inner wall of the water outlet pipe, and cleaning more cleanly. In order to further improve the cleaning effect, especially the cleaning of the above-mentioned sealing groove, to ensure the sealing performance after cooperation with the sealing ring, the outer surface of one end of the scrubbing body 1001 extending out of the water outlet pipe is sleeved with a driven gear ring and this end is socket-connected with the end of the driving rod 9 and allows the scrubbing body 1001 to rotate in the water outlet pipe. During the specific production, the end of the driving rod 9 is made into an enlarged shape, for example, the shaft section at the end is made larger, and the enlarged end is installed in the scrubbing body 1001 and cooperates with the stepped hole in the scrubbing body 1001, so that the scrubbing body 1001 can rotate in the water outlet pipe and can be rotatably connected with the driving rod 9. The driven gear ring is connected to an external driving device with a gearbox to drive the scrubbing body 1001 to rotate; and in particular, after the movable shaft 1 of this embodiment stops moving and resets, the elastic inflatable rings 1002 of the scrubbing body 1001 are just located in the sealing groove of the inner wall of the outlet pipe. At this moment, starting the driving device can allow the elastic inflatable rings 1002 to fully and thoroughly clean the difficult-to-clean sealing grooves.

[0018] More specifically, in this embodiment, the transmission member 2 is slidably connected to the moving shaft 1, such as Figure 2 , a mounting plate 4 is fixedly provided below the transmission member 2, the moving shaft 1 can slide through the transmission member 2 and the mounting plate 4, and cylindrical springs 3 are sleeved on the moving shaft 1 between the hydraulic cylinder or pneumatic cylinder driving the moving shaft 1 and the transmission member 2, and between the mounting plate 4 and the transmission member 2. This design enables the transmission member 2 to have a restoring force when it moves up and down, so as to return to a natural state, and the two cylindrical springs 3 can also play a role in applying a flexible pressure to the transmission member 2 and improving the shaking effect of the transmission member 2 when it moves, and at the same time, the shaking effect of the contact plate 8 is also improved.

[0019] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
