DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0026] The utility model provides a submersible motor testing device, such as Figures 1 to 4 As shown, it includes a body 1, a workbench 2 rotatably arranged on the top of the body 1, a simulation well 3 opened on one side of the body 1 and a driving cylinder 4 obliquely arranged on the other side of the body 1, a detector 5 is arranged on one side of the workbench 2, a rotating sleeve 6 is horizontally arranged on the output end of the detector 5, a fixing part 7 for fixing a submersible motor 25 is arranged on the other side of the workbench 2, the output end of the driving cylinder 4 is fixedly connected to a side of the workbench 2 close to the detector 5, and the driving cylinder 4 can push the workbench 2 to rotate 90°.

[0028] Furthermore, the connecting member 10 includes a first connecting hole 10a formed on the second fixing block 8 and a connecting rod 10b threadedly connected to the first connecting hole 10a, and the first fixing block 7a is provided with a second connecting hole 13 threadedly connected to the connecting rod 10b.

[0029] Furthermore, a first positioning block 14 cooperating with the submersible motor 25 is symmetrically arranged on the top of the third fixing block 11 .

[0030] Furthermore, the workbench 2 is symmetrically provided with a long strip of movable grooves 15, and movable blocks 16 matching the movable grooves 15 are arranged on both sides of the third fixed block 11. A movable rod 17 is threadedly connected to the movable block 16 along the vertical direction, and a plurality of third connecting holes 18 are evenly provided in the movable groove 15. The bottom of the movable rod 17 can be threadedly connected to the third connecting hole 18.

[0031] Furthermore, a positioning hole 19 is provided on the workbench 2 , and a second positioning block 20 is horizontally provided on the machine body 1 . When the second positioning block 20 moves through the positioning hole 19 , the workbench 2 is in a vertical direction.

[0032] Furthermore, a third positioning block 21 is vertically arranged at one end of the workbench 2 close to the detector. When the third positioning block 21 abuts against the machine body 1, the workbench 2 is in a horizontal direction.

[0033] Furthermore, a first elastic connection layer 22 is disposed at the bottom end of the third positioning block 21 .

[0034] Furthermore, the inner walls of the first fixing block 7 a and the second fixing block 8 are both provided with a second elastic connection layer 23 .

[0035] Furthermore, a rotating handle 24 is provided at one end of the connecting rod 10b.

[0036] When it is necessary to test the performance of the submersible motor 25 (mainly to test the speed of the rotor output of the submersible motor 25), first rotate the connecting rod 10b to separate the connecting rod 10b from the second connecting hole 13, and rotate the second fixing block 8 outward to place the submersible motor 25 on the first fixing block 7a of the workbench 2, push the submersible motor 25 forward to connect the rotating shaft sleeve 6 with the rotor of the submersible motor 25, and then make the base of the submersible motor 25 engage with the third fixing groove 12 on the third fixing block 11, and at the same time, the first positioning block 14 engages with the opening of the base of the submersible motor 25, connect the base end of the submersible motor 25 to the power supply, rotate the second fixing block 8 to make the top of the submersible motor 25 fit into the second fixing groove 9, and then rotate the connecting rod 10b to make the connecting rod 10b threadedly connected with the second connecting hole 13, so as to achieve the desired effect. The submersible motor 25 is fixed on the workbench 2, and then the driving cylinder 4 is turned on. The output end of the driving cylinder 4 pushes the side of the workbench 2 close to the detector 5 obliquely upward, thereby pushing the side of the workbench 2 close to the submersible motor 25 to rotate downward 90°, so that the base of the submersible motor 25 enters the simulated well 3 (in the actual working process, the simulated well 3 is dug from the ground to simulate the real working state of the submersible motor 25). Finally, the power is turned on, and the submersible motor 25 converts electrical energy into mechanical energy output. The detector 5 is mainly used to detect the speed output by the submersible motor 25; by setting the simulated well 3 and the driving cylinder 4, etc., the submersible motor 25 is driven in a vertical state for detection, simulating the real working state of the submersible motor 25, thereby realizing the simulation test of the submersible motor 25 and ensuring the accuracy and reliability of the test results.

[0037] By setting the first fixing block 7a, the second fixing block 8, etc., the submersible motor 25 is fixed between the first fixing block 7a and the second fixing block 8, and the base of the submersible motor 25 is engaged with the third fixing block 11, thereby achieving the fixation of the submersible motor 25, with a simple structure and convenient operation.

[0038] By setting the movable groove 15, the movable block 16, etc., the position of the third fixed block 11 can be adjusted according to the length of the submersible motor 25, so that the third fixed block 11 and the first positioning block 14 can always cooperate with the base of the submersible motor 25 to ensure the tightness of the connection between the submersible motor 25 and the workbench 2.

[0039] By setting the first positioning block 14, the first positioning block 14 is just engaged with the opening of the base of the submersible motor 25, so that the connection between the submersible motor 25 and the third fixing block 11 is tighter. At the same time, when the submersible motor 25 is in a vertical state, the base of the submersible motor 25 is in contact with the first positioning block 14 and the third fixing block 11, which can reduce the effect of the gravity of the submersible motor 25 on the first fixing block 7a and the second fixing block 8, so that the connection between the submersible motor 25 and the workbench 2 is more stable.

[0040] By setting the second positioning block 20 and the positioning hole 19, when the workbench 2 is in a vertical state, the second positioning block 20 passes through and fits into the positioning hole 19, which can not only limit the workbench 2, but also increase the connection between the workbench 2 and the body 1, so that the device is more stable when the workbench 2 is in a vertical state.

[0041] By providing the third positioning block 21 , when the workbench 2 is in a horizontal state, the third positioning block 21 abuts against the machine body 1 , thereby limiting the position of the workbench 2 and making the workbench 2 more stable.

[0042] By providing the second elastic connection layer 23 , the friction between the first fixing block 7 a and the second fixing block 8 and the submersible motor 25 is increased, so that the first fixing block 7 a and the second fixing block 8 have a better fixing effect on the submersible motor 25 .

[0043] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0044] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention.
