[0020] See also Figures 1 to 3 , which is the first embodiment of the utility model, and this embodiment provides a technical solution: a multifunctional hydraulic water pump for oilfield well repairing operation, comprising a pump body 1 and a water inlet 2 arranged at the bottom end of the pump body 1, a metal mesh cover 3 is installed at the bottom of the water inlet 2, which has a certain filtering function and can prevent some larger foreign matter from entering the interior of the pump body 1 when water is inletted, a pipe connection port 4 is arranged on one side of the water inlet 2, a hydraulic motor 5 is installed at the top end of the pump body 1, an integrated annular seat 21 is arranged on the bottom surface of the water inlet 2, the top end of the metal mesh cover 3 is sleeved on the surface of the annular seat 21, and a quick disassembly mechanism 6 is arranged between the metal mesh cover 3 and the annular seat 21;

[0021] The quick disassembly mechanism 6 includes an inner seat block 61 welded and fixed to the inner wall of the metal mesh cover 3, an inner slide groove 62 is provided in the inner seat block 61, a spring 63 and an inner slide block 64 are provided in the inner slide groove 62, two side rods 65 are fixed to one side of the inner slide block 64, the ends of the two side rods 65 penetrate the surface of the inner seat block 61 and are fixed with a clamping plate 66, the top end of the clamping plate 66 is inserted into the inner side of the annular seat 21, and a limiting clamping block 67 is welded and fixed to the top surface of the clamping plate 66, and a limiting clamping groove 68 corresponding to the limiting clamping block 67 is provided on the inner wall of the annular seat 21, and the limiting clamping block 67 is inserted into the limiting clamping groove 68, which can be The inner seat block 61 and the metal mesh cover 3 are stably limited to achieve a stable connection between the metal mesh cover 3 and the annular seat 21. A pressure block 69 is fixed to the other side surface of the inner slider 64, and the end of the pressure block 69 passes through the outside of the metal mesh cover 3. Subsequently, it is only necessary to press the pressure block 69 to move the inner slider 64 sideways to compress the spring 63, and to move the side rod 65 sideways with the card plate 66 until the limiting card block 67 moves out of the limiting card slot 68, so that the limiting of the inner seat block 61 and the metal mesh cover 3 can be released. At this time, the metal mesh cover 3 can be moved down, and the separation of the metal mesh cover 3 and the water inlet 2 can be quickly completed, which is convenient for subsequent inspection and maintenance.
