[0002] At present, downhole turbine generators are used as power supply for high-temperature wireless inclinometers while drilling, rotary steering, electromagnetic wave and other instruments. Compared with lithium battery power supply, they are not limited by battery life, have high power, save costs, and are clean energy.

[0003] During the production and maintenance process of underground turbine generators, inspection equipment is required to test their overall performance parameters to ensure that the underground turbine generators can provide stable and reliable electricity when working. The overall performance testing equipment of underground turbine generators usually includes a carrier tool, a drive motor, a motor inverter, a clamping device, a speed sensor and a speed display, etc. The working principle is that the motor inverter changes the speed of the drive motor, the drive motor drives the turbine of the underground turbine generator to rotate, and the speed sensor detects the turbine speed and displays it on the speed display.

[0004] The existing downhole turbine generator overall performance testing equipment has the following shortcomings or deficiencies: 1. The driving motor directly drives the turbine of the downhole turbine generator to rotate. If the turbine of the downhole turbine generator cannot move relative to the generator body due to a fault, it is easy to cause damage to the instrument and even personal injury; 2. The existing testing equipment can only detect and display one parameter, the speed of the downhole turbine generator, and the function is single; 3. The driving motor, motor inverter, clamping device, etc. in the existing testing equipment are inseparable from the carrying tool as an integrated structure, and the clamping device is relatively low, which is inconvenient to operate. Therefore, the existing testing equipment cannot meet the actual needs. Utility Model Content

[0005] The utility model aims to provide a downhole turbine generator test bench for a high-temperature wireless inclinometer while drilling, which can overcome the shortcomings of the prior art and provide a highly efficient, comprehensive and easy-to-operate test bench.

[0006] The technical solution adopted by the utility model is:

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figure 1 and 2 As shown, the utility model includes a tool cart 6, a carrier plate 5 arranged on the tool cart 6, a drive motor 1 arranged on the carrier plate 5, a clamping device 3, a speed sensor 4, a motor inverter 10 and a three-phase multifunctional ammeter 7.

[0020] The clamping device 3 is composed of a coupler 11, a limit ring 12, an outer cylinder 13, and a locking ring 14. The downhole turbine generator 2 is fixedly arranged in the outer cylinder 13. The turbine power generation end of the downhole turbine generator 2 is fixedly arranged with the inner wall of the outer cylinder 13 through the limit ring 12. The output end of the downhole turbine generator 2 is arranged outside the outer cylinder 13 and fixedly matched with the outer cylinder 13 through the locking ring 14.

[0021] The motor frequency converter 10 controls the drive motor 1, and the output shaft of the drive motor 1 is rotationally connected to the coupler 11 through a synchronous wheel and a synchronous belt. The output end of the downhole turbine generator 2 is connected to the input end of the three-phase multi-function meter 7 for displaying parameters such as voltage, current, and frequency;

[0022] It also includes a speed display 9 and an alarm 8 . The output end of the speed sensor 4 is connected to the input end of the speed display 9 , and the output end of the speed display 9 is connected to the input end of the alarm 8 .

[0023] It also includes a tool panel, which is vertically arranged on one side of the carrier plate. The three-phase multifunctional electric meter 7, the alarm 8, the speed display 9, and the motor inverter 10 are respectively fixed on the tool panel, which makes operation and data reading more convenient.

[0024] The carrying plate 5 and the tool cart 6 are detachably arranged, and the carrying plate 5 is fixed to the tool cart by a limiting fixing part. There are multiple limiting fixing parts on the tool cart 6, which are used to adjust the height of the upper layer of the tool cart 6, and then adjust the test height. In actual use, the carrying plate 5 is placed on different workbenches to adapt to more inspection and testing scenarios. The carrying plate 5 is fixed to the upper layer of the tool cart 6. By adjusting the height of the upper layer of the tool cart 6, the test height can be adjusted, and the operation is more convenient.

[0025] When the utility model is actually used, the downhole turbine generator 2 is installed in the outer cylinder 13 of the clamping device 3 and is positioned by the limiting ring 12. The locking ring 14 is connected to the outer cylinder 13 through a thread. The locking ring 14 is rotated to shrink the tail of the outer cylinder 13, thereby locking the downhole turbine generator 2.

[0026] During specific operation, the motor inverter 10 controls the driving motor 1 to rotate, and the driving motor 1 rotates the coupler 11 in the clamping device 3 through the synchronous wheel and the synchronous belt. The coupler 11 is fixed on the outer cylinder 13 through the bearing. When the coupler rotates, the outer cylinder 13 and the downhole turbine generator 2 are stationary. The rotation of the coupler 11 drives the internal rotor of the downhole turbine generator 2 to rotate by magnetic coupling, so that the downhole turbine generator 2 generates electrical energy. The speed sensor 4, the speed display 9, and the alarm 8 are connected together through wires. The speed sensor 4 senses the speed of the coupler 11 and transmits the speed signal to the speed display 9 for display. The speed display 9 can set the speed threshold. When the speed is too low or too high, the alarm 8 flashes and emits an alarm sound.

[0027] The utility model adjusts the output speed of the driving motor 1 by the knob on the motor frequency converter 10, thereby changing the speed of the coupler 11. The coupler 11 replaces the turbine of the downhole turbine generator 2, and drives the internal rotor of the downhole turbine generator 2 to rotate by magnetic coupling, thereby simulating different working conditions of the downhole turbine generator 2. The three-phase multifunctional ammeter 7 is connected to the output end of the downhole turbine generator 2 through a wire. The electric energy data output by the downhole turbine generator 2 under different speed working conditions, including parameters such as voltage, current, and frequency, are displayed by the three-phase multifunctional ammeter 9. The overall performance parameters of the downhole turbine generator 2 are determined by analyzing the electric energy data, thereby achieving the purpose of testing and inspecting the downhole turbine generator 2.

[0028] In the utility model, the downhole turbine generator is installed on the clamping device, and the motor frequency converter controls the operation of the driving motor. By adjusting the knob on the motor frequency converter, the driving motor is controlled to output different speeds. The driving motor drives the coupler in the clamping device to rotate. The coupler replaces the turbine of the downhole turbine generator and has no direct contact with the downhole turbine generator. The internal rotor of the downhole turbine generator is rotated by magnetic coupling to enable the downhole turbine generator to output electrical energy. Furthermore, the rotation signal of the coupler is received by the speed sensor, and the speed of the coupler is displayed by the speed display. The three-phase multifunctional meter detects the electrical energy output by the downhole turbine generator at different speeds, and displays parameters such as voltage, current, and frequency. The overall performance parameters of the downhole turbine generator are judged by analyzing the electrical energy data, and then the test is completed. The overall convenience and speed!
