[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] See also Figure 1-3 The utility model provides the following technical solutions: a wear-resistant water pump body, comprising a base plate 1, a pulley mounting position adjustment mechanism 2 is installed inside the base plate 1, a mounting plate 3 is installed on the upper end of the base plate 1, a wear-resistant protective cover 6 is installed on the upper end of the mounting plate 3, a submersible pump body fixing mechanism 7 is installed inside the mounting plate 3, a submersible pump body 5 is installed inside the wear-resistant protective cover 6, and a drive shaft 4 is installed on the output end of the submersible pump body 5.

The mounting block 22 is mounted at the inner corner of the bottom plate 1, the pulley 24 is rotatably connected and mounted at the lower end of the mounting block 22, a mounting groove 29 is provided at the inner corner of the bottom plate 1, a slide plate 28 is installed inside the side of the mounting groove 29, a spring 27 is installed on one side of the slide plate 28, a fixing rod 1 23 is installed on the upper end of the other side of the slide plate 28, a fixing rod 26 is installed on the lower end of the other side of the slide plate 28, and a fixing hole 25 is provided on the side of the mounting block 22.

[0023] By adopting the above technical solution, when the fixing hole 25 on the side of the mounting block 22 is correspondingly plugged into the fixing rod 26, the pulley 24 is in contact with the ground, so that relative sliding can be generated between the pulley 24 and the ground. When the device moves to the bottom of the water, the sliding slide 28 is used to drive the spring 27 to compress and drive the fixing rod 26 to slide out from the inside of the fixing hole 25, and then the mounting block 22 is slid upward. When the fixing rod 1 23 is aligned with the fixing hole 25, the spring 27 rebounds, thereby driving the fixing rod 1 23 to be inserted into the inside of the fixing hole 25 to achieve the installation and fixation of the mounting block 22. At this time, the pulley 24 is located inside the bottom plate 1, thereby ensuring the stability of the device at the bottom of the water.

[0024] Specifically, a sliding groove 21 corresponding to the sliding plate 28 is provided at the inner corner of the bottom plate 1 and is slidably connected thereto.

[0026] When the present embodiment is in use, when the fixing hole 25 on the side of the mounting block 22 is correspondingly plugged with the fixing rod 26, the pulley 24 is in contact with the ground, so that relative sliding can be generated between the pulley 24 and the ground. When the device moves to the bottom of the water, the sliding plate 28 drives the spring 27 to compress, and drives the fixing rod 26 to slide out from the inside of the fixing hole 25, and then the mounting block 22 slides upward. When the fixing rod 1 23 is aligned with the fixing hole 25, the spring 27 rebounds, thereby driving the fixing rod 1 23 to be inserted into the inside of the fixing hole 25, so as to realize the installation and fixation of the mounting block 22. At this time, the pulley 24 is located inside the bottom plate 1, so as to ensure the stability of the device under water.

A bidirectional screw rod 76 is rotatably connected and installed on one side of the inner side of the mounting plate 3. A turning handle 74 is installed on one end of the bidirectional screw rod 76. Two groups of nut blocks 75 are symmetrically installed on the surface of the bidirectional screw rod 76. An H-shaped connecting plate 73 is installed on the upper end of the nut block 75. A connecting rod 78 is installed on the side edge of the H-shaped connecting plate 73. The other end of the connecting rod 78 is located inside the wear-resistant protective cover 6 and is installed with an arc-shaped clamping plate 77. The connecting rod 78 and the wear-resistant protective cover 6 are slidably connected through a through hole.

[0029] By adopting the above technical solution, by rotating the handle 74, the rotation of the handle 74 drives the bidirectional screw rod 76 to rotate, and the rotation of the bidirectional screw rod 76 drives the two groups of nut blocks 75 to approach each other, and the sliding of the two groups of nut blocks 75 drives the H-shaped connecting plate 73 to slide, and the sliding of the H-shaped connecting plate 73 drives the connecting rod 78 to move, and the movement of the connecting rod 78 drives the arc-shaped clamping plate 77 to fix the submersible pump body 5.

[0030] Specifically, the submersible pump body fixing mechanism 7 further includes a slider 71 and a slider 72. The slider 71 is installed on the other side of the lower end of the H-shaped connecting plate 73. The slider 71 is installed through the inside of the slider 71.

[0031] By adopting the above technical solution, when the H-shaped connecting plate 73 slides, it can drive the sliding block 71 to slide on the surface of the sliding rod 72, thereby improving the stability of the sliding process of the H-shaped connecting plate 73.

[0032] Specifically, a sliding groove corresponding to the nut block 75 and the slider 71 is opened at the upper end of the mounting plate 3 and is slidably connected thereto.

[0033] By adopting the above technical solution, when the H-shaped connecting plate 73 slides, it can drive the nut block 75 and the sliding block 71 to slide inside the sliding groove, thereby further improving the stability of the sliding process of the H-shaped connecting plate 73.

[0034] When the present embodiment is in use, by rotating the turning handle 74, the turning handle 74 drives the bidirectional screw rod 76 to rotate, and the rotation of the bidirectional screw rod 76 drives the two sets of nut blocks 75 to approach each other, and the two sets of nut blocks 75 slide and drive the H-shaped connecting plate 73 to slide, and the sliding of the H-shaped connecting plate 73 drives the connecting rod 78 to move, and the movement of the connecting rod 78 drives the arc clamping plate 77 to fix the submersible pump body 5, and at the same time, when the H-shaped connecting plate 73 slides, it drives the slider 71 to slide on the surface of the slide rod 72, thereby improving the stability of the sliding process of the H-shaped connecting plate 73.

[0035] Working principle and use process of the utility model: When the utility model is in use, when the fixing hole 25 on the side of the mounting block 22 is correspondingly plugged into the fixing rod 26, the pulley 24 is in contact with the ground, so that relative sliding can be generated between the pulley 24 and the ground. When the device moves to the bottom of the water, the sliding plate 28 is used to compress the spring 27, and drive the fixing rod 26 to slide out from the inside of the fixing hole 25, and then the mounting block 22 is slid upward. When the fixing rod 1 23 is aligned with the fixing hole 25, the spring 27 rebounds, thereby driving the fixing rod 1 23 to be inserted into the inside of the fixing hole 25, so as to realize the installation and fixation of the mounting block 22. At this time, the pulley 24 is located inside the bottom plate 1. Thereby ensuring the stability of the device at the bottom of the water, through the provision of the wear-resistant protective cover 6, it is convenient to protect the submersible pump body 5, thereby improving the wear resistance and protection of the submersible pump body 5; by rotating the handle 74, the rotation of the handle 74 drives the bidirectional screw 76 to rotate, and the rotation of the bidirectional screw 76 drives the two groups of nut blocks 75 to approach each other, and the sliding of the two groups of nut blocks 75 drives the H-type connecting plate 73 to slide, and the sliding of the H-type connecting plate 73 drives the connecting rod 78 to move, and the movement of the connecting rod 78 drives the arc clamping plate 77 to fix the submersible pump body 5, and at the same time, when the H-type connecting plate 73 slides, it will drive the slider 71 to slide on the surface of the slide rod 72, thereby improving the stability of the sliding process of the H-type connecting plate 73.
