Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figure 1-4 The present invention provides the following technical solution: an infrared temperature measuring device for a hydro-generator, comprising an electric slide table 1, wherein two electric slide tables 1 are provided, an electric slider 2 is provided on the outer side of the electric slide table 1, a connecting cavity assembly 3 is provided between the two electric sliders 2, an infrared temperature measuring probe assembly 5 is installed at the upper position of the connecting cavity assembly 3, the connecting cavity assembly 3 is connected to the two electric sliders 2 by an adjusting lifting device 4, and an auxiliary support device 6 is fixedly installed below the electric slide table 1.

[0023] Specifically, the adjustment and lifting device 4 includes a connecting frame 41, a reduction motor 42, a guide rod 43, a moving block 44, a lead screw 45, and a lifting and lighting assembly 46. The connecting frame 41 is fixedly installed above the two electric sliders 2. The reduction motor 42 is fixedly installed on one side of the connecting frame 41. The lead screw 45 is fixedly installed on the side of the output end of the reduction motor 42 near the connecting frame 41. The moving block 44 is installed on the outer side of the lead screw 45 by thread. The guide rod 43 is fixedly installed on the inner side of the connecting frame 41 and above the lead screw 45. The lifting and lighting assembly 46 is installed between the moving block 44 and the connecting cavity assembly 3.

[0024] By adopting the above technical solution, the staff can further adjust the left and right positions of the infrared temperature measuring probe assembly 5 according to the size and model of the hydro-generator when needed, thereby ensuring that the infrared temperature measuring probe assembly 5 can contact the temperature measuring positions of the hydro-generator.

[0025] Specifically, the lifting lighting assembly 46 includes an electric telescopic rod 461 and a transparent shell 463. The transparent shell 463 is fixedly installed on the side of the connecting cavity assembly 3 near the moving block 44, and the transparent shell 463 is connected to the moving block 44 through the electric telescopic rod 461.

[0026] By adopting the above technical solution, the staff can further adjust the vertical position of the infrared temperature probe assembly 5 according to the size and model of the hydro-generator when needed, thereby ensuring that the infrared temperature probe assembly 5 can contact the temperature measurement positions of the hydro-generator.

[0027] Specifically, the lifting lighting assembly 46 also includes lighting lamps 462, and multiple lighting lamps 462 are fixedly installed on the inside of the transparent shell 463.

[0028] By adopting the above technical solution, staff can use the various lights 462 to provide auxiliary lighting to the surroundings when needed, thereby better coping with situations where there is insufficient light and ensuring the normal progress of work.

[0029] In this embodiment, when the device is needed to perform infrared temperature measurement on the hydro-generator, the operator places the device outside the hydro-generator, connects it to an external power source, and manipulates the two electric sliding tables 1 and two electric sliders 2 to adjust the position of the connecting cavity assembly 3 and other structures. Then, the operator manipulates the infrared temperature probe assembly 5 to rotate along the connecting cavity assembly 3 to the required position. If the infrared temperature probe assembly 5 cannot contact the temperature measurement position of the hydro-generator, the operator can activate the reduction motor 42 in the adjustment and lifting device 4 and the electric telescopic rod 461 in the lifting and lighting assembly 46. The reduction motor 42 drives the lead screw 45 to rotate, and the lead screw 45 connects with the connecting cavity assembly 3. The frame 41 is connected by bearings, the lead screw 45 is threadedly connected to the moving block 44, and the moving block 44 is slidably connected to the guide rod 43. Therefore, the lead screw 45 drives the moving block 44 and other structures to move, thereby adjusting the left and right position of the infrared temperature measuring probe assembly 5. The electric telescopic rod 461 drives the transparent shell 463 and other structures to move up and down, thereby adjusting the up and down position of the infrared temperature measuring probe assembly 5, so that the infrared temperature measuring probe assembly 5 contacts the temperature measuring position of the water turbine generator. Then, infrared temperature measurement can be performed through the infrared temperature measuring probe assembly 5. When needed, the staff can turn on the various lighting lamps 462 to provide auxiliary lighting for the surroundings.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the auxiliary support device 6 includes a vertical plate 61, screws 62, an L-shaped plate 64 and a support plate 65. The vertical plate 61 is fixedly installed below the electric slide table 1, and the support plate 65 is fixedly installed below the vertical plate 61. Multiple screws 62 are threadedly installed on the edge of the support plate 65, and the L-shaped plate 64 is installed on the outer side of the screws 62 through bearings.

[0032] By adopting the above technical solution, the staff can adjust the height of each L-shaped plate 64 by manipulating each screw 62 when needed, thereby keeping the device stable on uneven ground and ensuring the normal operation of the work.

[0033] Specifically, the auxiliary support device 6 also includes an anti-slip rubber pad 63, which is fixedly installed under the L-shaped plate 64.

[0034] By adopting the above technical solution, the device can enhance the friction between itself and the ground through the anti-slip rubber pad 63, thereby reducing the possibility of the device moving unexpectedly and ensuring the normal operation of the work.

[0035] In this embodiment, when the device is placed on an uneven surface, the operator can rotate the screws 62 in the two auxiliary support devices 6 according to the surface conditions. The screws 62 are threadedly connected to the support plate 65, and the screws 62 are also connected to the L-shaped plates 64 by bearings. The inner sides of each L-shaped plate 64 are in contact with the outer sides of the support plate 65, so each screw 62 drives each L-shaped plate 64 to move, thereby adjusting the height of each L-shaped plate 64 and the anti-slip rubber pad 63 below it, thus keeping the device stable. The upright plate 61 plays a supporting role.

[0036] The structure and principle of the electric slide table 1, electric slider 2, connecting cavity assembly 3 consisting of a connecting cavity, slide rail, and driven rack, and infrared temperature measuring probe assembly 5 consisting of a sliding rod, movable block, rotating shaft, driving gear, servo motor, slider, infrared temperature measuring probe, and ball bearings in this utility model have been disclosed in an infrared temperature measuring device for a hydro-generator set disclosed in Chinese Patent Application No. 201822140709.8. Its working principle is that during use, the connecting cavity can be placed outside the generator set via a support frame. When it is necessary to detect the temperature of the generator set, the electric slider can be moved to the electric slide table. The connecting cavity is adjusted forward and backward by relative sliding, allowing it to move at the top of the generator set. An infrared temperature sensor measures the temperature of the generator set. Simultaneously, a servo motor can be started, which drives the drive gear to rotate inside the movable block via a rotating shaft. The drive gear meshes with the driven rack inside the connecting cavity, causing the movable block to slide along the slide rail via a sliding rod and slider. This movement of the movable block drives the infrared temperature sensor to measure the temperature of each end face of the generator set inside the connecting cavity. It is simple, practical, and convenient.

[0037] The working principle and usage process of this utility model are as follows: When it is necessary to use the device to perform infrared temperature measurement on a hydro-generator, the operator places the device outside the hydro-generator, connects it to an external power source, and manipulates the two electric sliding tables 1 and two electric sliders 2 to adjust the position of the connecting cavity assembly 3 and other structures. Then, the operator manipulates the infrared temperature measuring probe assembly 5 to rotate along the connecting cavity assembly 3 to the required position. If the infrared temperature measuring probe assembly 5 cannot contact the temperature measuring position of the hydro-generator, the operator can activate the reduction motor 42 in the adjusting and lifting device 4 and the electric telescopic rod 461 in the lifting and lighting assembly 46. The reduction motor 42 drives the lead screw 45 to rotate. The lead screw 45 is connected to the connecting frame 41 by a bearing, and the lead screw 45 is threadedly connected to the moving block 44. The moving block 44 is slidably connected to the guide rod 43. Therefore, the lead screw 45 drives the moving block 44 and other structures to move, thereby adjusting the left and right position of the infrared temperature measuring probe assembly 5. The electric telescopic rod 461 drives... The transparent shell 463 and other structures move up and down to adjust the vertical position of the infrared temperature probe assembly 5, thereby bringing the infrared temperature probe assembly 5 into contact with the temperature measurement position of the hydro-generator. Then, infrared temperature measurement can be performed through the infrared temperature probe assembly 5. When needed, the staff can turn on the various lighting lamps 462 to provide auxiliary lighting to the surroundings. When the device is on uneven ground, the staff can rotate the screws 62 in the two auxiliary support devices 6 according to the ground conditions. The screws 62 are threadedly connected to the support plate 65, and the screws 62 are connected to the L-shaped plates 64 by bearings. The inner sides of each L-shaped plate 64 are in contact with the outer sides of the support plate 65, so each screw 62 drives each L-shaped plate 64 to move, thereby adjusting the height of each L-shaped plate 64 and the anti-slip rubber pad 63 below it, thus keeping the device stable. The upright plate 61 plays a supporting role.
