According to an embodiment of the invention, the outer surface of the front end of the mounting block 11 is provided with a threaded hole 13, a bolt 14 penetrates through the threaded hole 13, the bolt 14 penetrates through the threaded hole 13 and extends to the inside of the notch 12 to be in threaded connection with the notch, and the bolt 14 penetrates through the threaded hole 13 to be in threaded connection with the mounting block 11, so that the stability of the stop block is improved, and the stop block is prevented from being separated from the slotted hole 8 due to large impact force of water flow in the device.

As an embodiment of the invention, the outer surface of the front end of the baffle 10 is provided with a fixing hole, and the inside of the fixing hole is fixedly connected with a transparent observation window 15, so that a worker can observe the filtering condition inside the horizontal connecting pipe 1 through the transparent observation window 15 conveniently, and the worker can clean the horizontal connecting pipe conveniently in time.

The working principle is as follows: by arranging the connecting mechanism 4, in the installation process, an operator holds the PVC pipe for main drainage by hands to enable the PVC pipe to be positioned inside the connecting ring 431 arranged at one end of the first vertical connecting pipe 2, then twists and turns the connecting block 41 to enable the metal elastic sheet 432 arranged inside the first mounting groove 43 to be tightly attached to the PVC pipe, and the PVC pipe extrudes the metal elastic sheet 432 in the process of moving towards the inside of the connecting ring 431 until the PVC pipe cannot move, then utilizes the heating plate 433 to heat the metal elastic sheet 432, the metal elastic sheet 432 is inserted into the PVC pipe under the action of high temperature, then enables the metal elastic sheet 432 to be naturally cooled, thereby enabling the metal elastic sheet 432 to be positioned inside the PVC pipe and be bonded and fixed with the PVC pipe, the device is convenient for connection between the PVC pipe and the PVC pipe joint, and compared with the direct threaded connection between the PVC pipe and the PVC pipe joint, the metal elastic sheet 432 can be inserted into the PVC pipe at high temperature to be connected, when the metal elastic sheet 432 is naturally cooled, the metal elastic sheet 432 is fixedly connected with the metal elastic sheet 432, so that the sealing performance of the device is improved; through setting up fixed establishment 5, operating personnel places the device level on ground when installation, then utilize and insert post 54 to run through mounting hole 53 and fix the device on ground, thereby improve the stability of device, simultaneously in-process when using, PVC pipe and device are when receiving water flow impact and producing the vibration, horizontal connecting pipe 1 promotes connecting plate 51 and removes in the inside of fixed frame 52, stopper 56 moves at the inside of movable groove 55 along connecting rod 57 under the promotion of connecting plate 51, and extrusion spring 58, the device, when utilizing to insert post 54 fixed to it, can effectually slow down the vibration, reduce the device and the junction of PVC pipe because water flow impact produces the cracked probability of vibration for a long time.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
