Description

Technical Field

[0001] The utility model relates to the technical field of sewage pump couplers, in particular to a surface contact coupling device for a sewage pump. Background Art

[0002] A sewage pump is a pump product that is connected to a motor and works underwater at the same time. Compared with general horizontal pumps or vertical sewage pumps, the sewage pump has a compact structure and occupies a small area. It is easy to install and maintain. Large sewage pumps are generally equipped with automatic coupling devices for automatic installation, which is very convenient for installation and maintenance. The continuous operation time is long. When the sewage pump is in use, it needs to be connected to the coupling device to optimize operation, facilitate maintenance, safety and extend the life of the equipment.

[0003] After searching the Chinese patent "A surface contact coupling device for a sewage pump", the publication number is "CN219570322U". This patent can generate pulling force on the coupling frame by pulling the sewage pump. The coupling frame can drive the guide slide groove to slide on the surface of the guide rod under the pulling force. In this way, when the sewage pump moves upward to the water surface, the sewage pump can be removed and repaired. Through this structure, the sewage pump is evenly stressed when pulled and is more stable. However, the installation of the sewage pump and the coupling device is more troublesome and unstable when connected, and it is not convenient to install the coupling device quickly and stably, which reduces the use effect of the device.

[0004] Therefore, a sewage pump surface contact coupling device is proposed to solve the above problems. Utility Model Content

[0007] Preferably, the installation mechanism also includes a compression spring arranged at one end of the first clamping block, and one end of the sewage pump body is provided with a plurality of evenly distributed first clamping grooves. The first clamping block is clamped with the first clamping grooves, so that the sewage pump can be quickly installed, thereby improving the use effect of the device.

[0008] Preferably, the other end of the inner wall of the sewage pump body is slidably connected to a fixing ring, one end of the fixing ring is fixedly connected to several evenly distributed fixing rods, the other end of the sewage pump body is rotatably connected to a threaded rod, and the threaded rod is threadedly connected to the fixing ring, so that the sewage pump can be quickly disassembled and repaired.

[0009] Preferably, the other end of the sewage pump body is threadedly connected with several evenly distributed fixing nuts, and one end of the fixing nuts is threadedly connected with the flange and the coupler body respectively, so that the sewage pump, the coupler and the flange can be quickly and stably installed and fixed, thereby improving the stability of the device.

[0010] Preferably, two positioning pins are provided on both sides of the bottom of the coupler body, so that the coupler can be quickly fixed.

[0011] Preferably, the fixing assembly includes a mounting ring rotatably connected to one end of the inner wall of the coupler body, one end of the mounting ring is fixedly connected to two second clamping blocks, and the other end of the flange is provided with two second clamping grooves matching the second clamping blocks, so that the coupler can be quickly installed, thereby improving the use effect of the device.

[0012] Preferably, a push plate is fixedly connected to the top end of the mounting ring, which can drive the second clamping block of the fixed ring fan to rotate.

[0013] Preferably, a limit rod is provided at the other end of the coupler body, one end of which passes through the coupler body and extends to the inner wall of the push plate, so as to fix the fixing ring and prevent the second clamping block from loosening during use.

[0014] The beneficial effects of the utility model are:

[0015] By setting up the installation mechanism, when the coupling device and the sewage pump are installed, one end of the first clamping block is an arc surface. When the sewage pump is installed, the first clamping block cooperates with the compression spring and moves into the flange, and is inserted into the first clamping groove to quickly install the sewage pump. The threaded rod is rotated to cooperate with the fixing ring to drive the fixing rod to squeeze the first clamping block in the first clamping groove, so that the sewage pipe can be quickly disassembled. The fixing nut can be rotated to install and fix the sewage pipe and the coupler, and its stability can be improved. The positioning nail can support and fix the coupler, and the sewage pump and the coupler can be quickly installed to improve the use effect of the device.

[0016] By setting up a fixing component, when installing the coupler, the coupler drives the two second clamping blocks to be inserted into the second clamping slot through the mounting ring, and the second clamping block is L-shaped. The mounting ring is rotated to drive the second clamping block to be clamped in the second clamping slot to quickly install and fix the coupler. The mounting ring can be driven to rotate by pulling the push plate, and the push plate can be quickly limited and fixed by the limit rod. The coupler can be quickly installed, which improves the convenience of its maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
