[0041] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0042] like Figure 1-5 As shown, according to an embodiment of this application, a low-power DC adjustable speed generator is proposed, comprising: a rotary motor assembly 100 having an output terminal, the rotary motor assembly 100 being used to drive the output terminal to rotate; a control circuit 200 electrically connected to the rotary motor assembly 100 for adjusting the rotation speed of the rotary motor assembly 100; a power supply system 300 electrically connected to the control circuit 200; and a speed gear 400 disposed at the output terminal of the rotary motor assembly 100.

[0043] The low-power DC adjustable speed generator provided in this application includes a rotating motor assembly 100, a control circuit 200, a power supply system 300, and a speed gear 400.

[0044] The rotary gear disk 400 is located at the output end of the rotary motor assembly 100. The control circuit 200 is electrically connected to the rotary motor assembly 100 and is used to regulate the current output to the rotary motor assembly 100. The power supply system 300 is electrically connected to the control circuit 200 and is used to provide energy to the control circuit 200.

[0045] During use, the rotation speed of the output end of the rotation motor assembly 100 is adjusted by adjusting the current output by the control circuit 200, so as to adjust the rotation speed of the rotation speed gear disk 400. The rotation speed probe is placed close to the rotation speed gear disk 400 to detect the rotation speed of the rotation speed gear disk 400. The detected rotation speed value by the rotation speed probe is compared with the rotation value of the output end of the rotation motor assembly 100. If the difference between the two is within the error range, the rotation speed probe is qualified; if the difference between the two exceeds the error range, the rotation speed probe needs to be repaired. At the same time, when inspecting the quality of the rotation speed probe, the output current of the control circuit 200 needs to be adjusted multiple times to achieve different rotation speeds of the rotation speed gear disk 400, and then the rotation speed of the rotation speed gear disk 400 at different rotation speeds is detected by the rotation speed probe, thereby further increasing the accuracy of the quality inspection of the rotation speed probe.

[0046] This technical solution provides a DC adjustable rotation speed generating device. By setting a rotation speed gear disk 400 that can determine the rotation speed, the integrity of the device of the rotation speed probe is detected, and there is no need to operate the equipment to rotate, which not only saves the procedures and energy consumed for verifying the integrity of the rotation speed probe, but also avoids the situation where the integrity of the rotation speed probe cannot be verified when the operating equipment does not have the condition for trial rotation. At the same time, this rotation speed generating device can adjust the rotation speed of the rotation speed gear disk 400. The rotation speed probe detects the rotation speed gear disk 400 at different rotation speeds and compares the detection result with the actual rotation speed, thereby further verifying the reliability of the rotation speed probe.

[0047] As Figure 1-5 As shown, the control circuit 200 includes: a DC motor speed regulator 210, which is electrically connected to the rotation motor assembly 100; a control knob 220, which is electrically connected to the DC motor speed regulator 210, and the control knob 220 is used to adjust the average current power output by the DC motor speed regulator 210; a first housing 230, the DC motor speed regulator 210 is arranged inside the first housing 230, and the control knob 220 is arranged outside the first housing 230; an output interface 240, which is arranged outside the first housing 230, and the output interface 240 is electrically connected to the DC motor speed regulator 210, and the control circuit 200 is connected to the rotation motor assembly 100 through the output interface 240.

[0048] In this technical solution, the control circuit 200 includes a DC motor speed regulator 210, a control knob 220, a first housing 230 and an output interface 240.

[0049] The DC motor speed controller 210 is electrically connected to the power supply system 300. The DC motor speed controller 210 is a device for regulating the speed of a DC motor. Since the DC motor has the characteristics of low speed and high torque, it cannot be replaced by an AC motor. Therefore, the DC motor speed controller 210 is set as a device for regulating the speed of the rotating motor assembly 100.

[0050] The DC motor speed controller 210, control knob 220, and output interface 240 are integrated into the first housing 230. The DC motor speed controller 210 is located inside the first housing 230 to prevent malfunctions caused by impacts or other issues. The control knob 220 is electrically connected to the DC motor speed controller 210 and is located outside the first housing 230. By rotating the control knob 220, the output current of the DC motor speed controller 210 can be adjusted. This arrangement facilitates the operator in adjusting the output speed of the rotating motor assembly 100. The output interface 240 is electrically connected to the DC motor speed controller 210 and is located outside the first housing 230. The output interface 240 is the output terminal of the control circuit 200 and is used for electrical connection to the rotating motor assembly 100.

[0051] like Figure 1-5 As shown, the power supply system 300 uses a low-voltage 12V power supply, or a 9V to 12V battery power supply.

[0052] In this technical solution, the power supply system 300 can be powered by a low-voltage 12V power supply or a 9V to 12V battery power supply. When the working site has power supply conditions, this DC adjustable speed generator can be powered by a low-voltage 12V power supply. When the working site does not have power supply conditions, it can be powered by a 9V to 12V battery power supply. This setting makes the use of the adjustable speed generator more flexible and not limited to the usage scenario with power supply conditions.

[0053] like Figure 1-5 As shown, the maximum rated current of the DC motor speed controller is 5A.

[0054] like Figure 1-5 As shown, the rotating motor assembly 100 includes: a motor body 110, which is a DC brushless motor with a speed range of 0 to 7200 r / pm; and a quick-connect connector 120, which is electrically connected to the motor body 110. The rotating motor assembly 100 is connected to the control circuit 200 through the quick-connect connector 120.

[0055] In this technical solution, the rotating motor assembly 100 includes a motor body 110 and a quick-connect wiring interface 120.

[0056] The motor body 110 has a speed range of 0 to 7200 r / pm, which can meet the requirements of the operating speed of the simulated operation equipment and further increase the reliability of the speed probe test.

[0057] The quick-connect connector 120 is electrically connected to the motor body 110. The quick-connect connector 120 is used to connect to the control circuit 200, thereby realizing the adjustment of the output speed of the motor body 110 through the control circuit 200.

[0058] like Figure 1-5 As shown, it also includes: an interface line, one end of which is used to connect to the quick-connect interface 120, and the other end is connected to the control circuit 200. The end of the interface line used to connect to the quick-connect interface 120 is a quick-connect connector, and the end of the interface line used to connect to the control circuit 200 is a three-head connector.

[0059] In this technical solution, the rotating motor assembly 100 and the control circuit 200 are connected by an interface cable. In this embodiment, when the interface cable is connected to the rotating motor assembly 100, it is actually connected to the quick-connect wiring interface 120. When the interface cable is connected to the control circuit 200, it is actually connected to the output interface 240 of the control circuit 200. The two ends of the interface cable connected to the quick-connect wiring interface 120 and the output interface 240 respectively use different connectors, which can effectively prevent misinsertion in actual operation.

[0060] like Figure 1-5 As shown, the rotating motor assembly 100 further includes a second housing 130, which includes a lower housing, an upper cover, and a rotating shaft. The upper cover is connected to the lower housing via the rotating shaft. When the lower housing and the upper cover are fastened together, the motor body 110 and the speed gear 400 are both located inside the second housing 130. An observation port is provided on one side of the second housing 130.

[0061] In this technical solution, the rotating motor assembly 100 also includes a second housing 130, which includes a lower housing, an upper cover, and a rotating shaft. During use, the upper cover is first opened, and the motor body 110 and the rotating gear 400 are placed inside the lower housing. Then the upper cover is fastened. This arrangement can protect the rotating gear 400 and prevent it from being damaged by impact or causing injury.

[0062] The second outer casing 130 has an observation port on its front side, through which the rotation speed probe can detect the rotation of the rotation speed disk 400.

[0063] like Figure 1-5As shown, it also includes: a mounting bracket, which includes a first mounting bracket and a second mounting bracket, the first mounting bracket being used to mount the second housing 130, and the second mounting bracket being used to mount the speed probe.

[0064] In this technical solution, the adjustable speed generating device also includes a mounting bracket, which includes a first mounting bracket and a second mounting bracket. During use, the second housing 130 is mounted on the first mounting bracket, and the speed probe is mounted on the second mounting bracket. It can be understood that after installation, the speed probe can observe the speed of the speed gear 400 through the observation port of the second housing 130.

[0065] This setup uses a first mounting bracket and a second mounting bracket to mount the rotating motor assembly 100 and the speed probe, eliminating the need for staff to hold the speed probe during testing, thus reducing the workload of staff. The speed probe is also more stable during the testing process, improving the testing results.

[0066] like Figure 1-5 As shown, the mounting bracket further includes a slide rail, with the first mounting bracket disposed at one end of the slide rail and the second mounting bracket slidably disposed on the slide rail.

[0067] In this technical solution, the mounting bracket also includes a slide rail. The first mounting bracket is fixedly set at one end of the slide rail, and the second mounting bracket is slidably set on the slide rail. After the rotating motor assembly 100 and the speed probe are installed, the distance between the speed probe and the speed gear 400 can be adjusted by sliding the second mounting bracket, making it easier to adjust the position of the speed probe to achieve the optimal observation distance and reducing the time cost of debugging the speed probe.

[0068] like Figure 1-5 As shown, the rotating gear disk 400 is a double-toothed disk.

[0069] In this technical solution, the rotation speed disk 400 adopts a double-tooth shape. This setting makes the rotation of the rotation speed disk 400 more obvious and easier to monitor, thereby further improving the accuracy of the speed probe detection and making it easier to control the integrity of the speed probe.
