Description

Technical Field

[0001] This utility model relates to the field of hydraulic dynamometer technology, specifically to the control mechanism of the inlet and outlet valves of a hydraulic dynamometer. Background Technology

[0002] A hydraulic dynamometer is a device that uses the energy transfer of water to measure power. The hydraulic dynamometer generates frictional torque through the interaction between water and a rotating rotor, thereby absorbing and transmitting the output power of the power machinery. The water inlet and outlet are precisely controlled by the hydraulic dynamometer's inlet and outlet valve control mechanism, so as to achieve precise measurement and adjustment of the output power of the power machinery.

[0003] The inlet and outlet pipes of existing hydraulic dynamometers are controlled by electric butterfly valves or ball valves to regulate the flow rate.

[0004] When adjusting the inlet and outlet flow rate of the existing hydraulic dynamometer inlet and outlet valve control mechanism, the inlet and outlet valves are separate, requiring adjustment of each valve separately, which increases the workload of the operator and is quite cumbersome. Therefore, we propose a hydraulic dynamometer inlet and outlet valve control mechanism. Utility Model Content

The rack plate 1 meshes with gear 1, and the rack plate 2 meshes with gear 2. Both rack plates 1 and 2 are installed in conjunction with drive gears. Both rack plates 1 and gear 1 are lower than the horizontal plane where rack plates 2 and gear 2 are located, transmitting driving force to adjust the inlet and drain valves.

[0009] Furthermore, the inlet and outlet valve control assembly also includes a spring, a sliding cylinder, and a fixed column. The fixed column is fixedly connected to the inner lower surface of the protective shell, the sliding cylinder is slidably connected to the outside of the fixed column, a spring is fixedly connected between the lower surface of the sliding cylinder and the fixed column, and the sliding cylinder is rotatably connected to the lower surface of the drive gear, automatically pushing the drive gear to move.

[0012] Furthermore, a worm gear is fixedly connected to the upper end of the outer surface of the limiting cylinder, and a worm is rotatably connected inside the protective shell. The worm meshes with the worm gear, causing the drive gear to rotate and lock.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figure 1-4 This embodiment provides a technical solution: a hydraulic dynamometer inlet and outlet valve control mechanism, including a protective shell 5, with an inlet pipe 1 and an outlet pipe 3 respectively provided on the lower left and right sides of the protective shell 5, an inlet valve 2 connected in series inside the inlet pipe 1, and an outlet valve 4 connected in series inside the outlet pipe 3, and also includes an inlet and outlet valve control component 14.

[0023] The inlet / outlet valve control assembly 14 includes a drive gear 1401, a sliding rod 1402, and a limiting cylinder 1403. The limiting cylinder 1403 is rotatably connected to the inside of the protective shell 5. The sliding rod 1402 is slidably connected within a slot inside the limiting cylinder 1403. The drive gear 1401 is fixedly connected to the lower surface of the sliding rod 1402. A worm gear 12 is fixedly connected to the upper end of the outer surface of the limiting cylinder 1403. A worm 13 is rotatably connected inside the protective shell 5, and the worm 13 meshes with the worm gear 12. It also includes a second knob 7, which is fixedly connected to the front end of the worm 13. A first gear 8 is rotatably connected to the left side of the inside of the protective shell 5. The lower surface of the first gear 8 is fixedly connected to the upper end of the valve stem inside the inlet valve 2. The right side of the inside of the protective shell 5... A second gear 10 is rotatably connected to the side. The lower surface of the second gear 10 is fixedly connected to the upper end of the valve stem inside the drain valve 4. A rack plate 9 and a rack plate 11 are slidably connected to the front and rear sides of the interior of the protective shell 5, respectively. The rack plate 9 meshes with a gear 8, and the rack plate 11 meshes with a gear 10. Both the rack plate 9 and the rack plate 11 are fitted with a drive gear 1401. The rack plate 9 and the gear 8 are both lower than the horizontal plane where the rack plate 11 and the gear 10 are located. The inlet and outlet valve control assembly 14 also includes a spring 1404, a sliding cylinder 1405, and a fixed column 1406. The fixed column 1406 is fixedly connected to the lower surface of the interior of the protective shell 5, and the sliding cylinder 1405 is slidably connected to the outside of the fixed column 1406. A spring 1404 is fixedly connected between the lower surface of the cylinder 1405 and the fixed post 1406. The sliding cylinder 1405 is rotatably connected to the lower surface of the drive gear 1401. When the drive gear 1401 moves downward, the sliding cylinder 1405 moves downward, and the spring 1404 contracts, causing the drive gear 1401 to mesh with the rack plate 9. At this time, rotating the knob 7 causes the worm gear 13 to rotate, which in turn drives the worm wheel 12 to rotate, causing the limit cylinder 1403 to rotate, which in turn drives the sliding rod 1402 to rotate, causing the drive gear 1402 to rotate, which in turn drives the rack plate 9 to move, causing the gear 8 to rotate, which in turn drives the valve stem of the inlet valve 2 to rotate, thereby adjusting the water inlet flow. At this time, the spring 1404 relaxes, pushing the sliding cylinder 1305 upward, which in turn drives the drive gear 1401 to move downward. The upward movement causes the drive gear 1401 to mesh with the rack plate 11. At this time, rotating the knob 7 rotates the worm gear 13, which in turn rotates the worm wheel 12, causing the limit cylinder 1403 to rotate. This, in turn, rotates the sliding rod 1402, causing the drive gear 1402 to rotate. This, in turn, causes the rack plate 11 to move, resulting in the rotation of the gear 10, which in turn rotates the valve stem of the drain valve 4, thereby adjusting the drainage volume. The inlet and outlet valve control assembly 14 also includes a movable block 1407, a fixed track cylinder 1408, a rotating track cylinder 1409, and a slider 1410. The fixed track cylinder 1408 is fixedly connected to the inside of the protective shell 5. A threaded groove is formed on the inner surface of the fixed track cylinder 1408, and the rotating track cylinder 1409 is rotatably connected inside the fixed track cylinder 1408.The outer surface of the rotating track cylinder 1409 has a track groove. A movable block 1407 is slidably connected inside the rotating track cylinder 1409. A slider 1410 is fixedly connected to the outer surface of the movable block 1407. The slider 1410 is slidably connected to both the track groove and the threaded slot. A knob 6 is fixedly connected to the upper surface of the rotating track cylinder 1409. Rotating the knob 6 causes the rotating track cylinder 1409 to rotate, which in turn causes the movable block 1407 to rotate, and consequently, the slider 1410 to rotate. Because the slider 1410 is limited by the threaded slot, it continues to rotate after leaving the horizontal track of the track groove. At this time, it is simultaneously subjected to… The threaded slot and the track groove limit the movement of slider 1410 downwards, causing movable block 1407 to move downwards. This causes the lower end of movable block 1407 to press against sliding rod 1402. When adjusting the drain valve flow, reverse knob 6. Rotating knob 6 causes rotating track cylinder 1409 to rotate, which in turn causes movable block 1407 to rotate, and slider 1410 to rotate. Because slider 1410 is limited by the threaded slot, it continues to rotate after leaving the horizontal track of the track groove. At this point, it is simultaneously limited by both the threaded slot and the track groove, causing slider 1410 to rotate upwards, thus moving movable block 1407 upwards.

[0024] The working principle of the hydraulic dynamometer inlet and outlet valve control mechanism provided by this utility model is as follows: The inlet pipe 1 is connected in series with the water injection pipe of the external hydraulic dynamometer, and the outlet pipe 3 is connected in series with the water outlet pipe of the external hydraulic dynamometer. When using this hydraulic dynamometer inlet and outlet valve control mechanism to adjust the inlet valve flow rate, the knob 6 is rotated. The rotation of knob 6 drives the rotating track cylinder 1409 to rotate, which in turn drives the movable block 1407 to rotate, and then drives the slider 1410 to rotate. Because the slider 1410 is limited by the threaded slot, the slider 1410 disengages from the horizontal track of the track groove. After the track continues to rotate, it is simultaneously limited by the threaded slot and the track groove, causing the slider 1410 to rotate and move downwards, driving the movable block 1407 to move downwards. The lower end of the movable block 1407 presses against the sliding rod 1402, causing the drive gear 1401 to move downwards, which in turn causes the sliding cylinder 1405 to move downwards. The spring 1404 contracts, causing the drive gear 1401 to mesh with the rack plate 9. At this point, rotating the knob 7 causes the worm gear 13 to rotate, driving the worm wheel 12 to rotate, causing the limiting cylinder 1403 to rotate, which in turn drives the sliding rod 1402 to rotate, causing... The drive gear 1402 rotates, causing the rack plate 9 to move, which in turn rotates the gear 8, causing the valve stem of the inlet valve 2 to rotate, thereby adjusting the inlet water flow. When adjusting the drain valve flow, the reverse knob 6 rotates, causing the rotating track cylinder 1409 to rotate, which in turn rotates the movable block 1407, causing the slider 1410 to rotate. Because the slider 1410 is limited by the threaded slot, it continues to rotate after leaving the horizontal track of the track groove. At this time, it is simultaneously limited by the threaded slot and the track groove, causing the slider 1410 to rotate. The steering wheel moves upward, causing the movable block 1407 to move upward. At this time, the spring 1404 relaxes, pushing the sliding cylinder 1305 upward, which in turn drives the drive gear 1401 to move upward, so that the drive gear 1401 meshes with the rack plate 11. Then, the knob 7 is rotated, causing the worm gear 13 to rotate, which in turn drives the worm wheel 12 to rotate, causing the limit cylinder 1403 to rotate, which in turn drives the sliding rod 1402 to rotate, causing the drive gear 1402 to rotate, which in turn drives the rack plate 11 to move, causing the gear 10 to rotate, which in turn drives the valve stem of the drain valve 4 to rotate, thereby adjusting the amount of drainage.

[0025] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
