Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of density gradient columns, in particular to a mobile density float precision salvaging tool. Background Art
[0002] A density gradient column is a device used to measure the density of a sample. It primarily measures the density of a sample by comparing the densities of different liquids. During measurement, the density gradient column is filled with liquids of different densities. Liquids of different densities will then stratify, with the denser the liquid, the closer it will be to the bottom of the column, while the smaller the density, the closer it will be to the top.
[0003] Floats of different densities are placed in the density gradient column. The floats will float in the liquid of corresponding density according to their own density. Then the sample is placed in the density gradient column. The sample will float in the liquid of corresponding density according to its own density. The density of the sample is then determined based on the float flush with the sample.
[0004] When the floats are sent for inspection, the density of each float needs to be confirmed and placed in the corresponding protective bottle. However, the salvage tool configured by the instrument can only salvage all the floats and samples together, and cannot distinguish the density of a single float. As a result, the density of each float needs to be tested again, which increases the subsequent operation steps and makes it inconvenient to use. Therefore, we propose a mobile density float precision salvage tool. Utility Model Content

When the overshot net A is lowered, the baffle will open, and the float can be salvaged by the overshot net A at this time.

[0022] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.
[0023] See also Figure 1-7 The utility model provides a technical solution: a mobile density float precision salvage tool, including a support frame 1, the top and bottom ends of the support frame 1 are metal rings, and three support rods are arranged between the two metal rings for support. When in use, the support frame 1 can be sleeved outside the density gradient column, and the top of the support frame 1 is fixedly connected to the load-bearing frame 11, and the bottom of the load-bearing frame 11 is fixedly connected to the mounting frame 12. The mounting frame 12 is rotatably connected to a winding rod 13, and one side of the mounting frame 12 is rotatably connected to a pulley A14, and the pulley A14 is fixedly docked with the end of the winding rod 13, and a traction rope 3 is wound on the winding rod 13. The traction rope 3 is a high-toughness thin wire of the fishing line type, which has a strong load-bearing capacity. At the same time, during the process of salvaging the float, it will not affect the operator's line of sight. The bottom end of the traction rope 3 is fixedly connected to a salvage tube net A4, which is a cylindrical net bag and can be used to salvage a single float.
[0024] Furthermore, in the process of salvaging a single float, the support frame 1 is placed outside the density gradient column, and then the reeling rod 13 is rotated to lower the traction rope 3, so that the overshot net A4 enters the density gradient column. As the overshot net A4 descends, according to the height of the required salvaged float, the overshot net A4 is lowered to the position below the float, and then the overshot net A4 is controlled to move directly below the float by the traction rope 3. Then the reeling rod 13 is rotated in the opposite direction to reel in the traction rope 3. During the reeling process, the traction rope 3 will pull the overshot net A4 to rise. At this time, the overshot net A4 can be used to salvage the single float located directly above it, and then the reeling rod 13 is used to continue to reel in the traction rope 3 until the overshot net A4 is removed from the density gradient column, and the single float in the overshot net A4 can be taken out.
[0025] Combined with attachment Figure 1 、 Figure 2 and Figure 3 As shown, the top of the load-bearing frame 11 is fixedly connected to the fixing frame 2, and the side of the fixing frame 2 close to the pulley A14 is rotatably connected to the pulley B21. A transmission belt 22 is provided between the pulley B21 and the pulley A14. The side of the load-bearing frame 11 away from the pulley B21 is fixedly connected to the motor 23. A reduction mechanism is provided inside the motor 23 to reduce the speed of the motor 23 to avoid excessive speed of the motor 23, which causes the overshot net A4 to rise too fast and causes the liquid in the density gradient column to become chaotic. The output end of the motor 23 is fixedly docked with the rotating shaft of the pulley B21.
[0026] Furthermore, when controlling the winding rod 13 to rotate, the motor 23 is started to drive the pulley B21 to rotate. At this time, the pulley B21 can drive the pulley A14 to rotate through the transmission belt 22. The rotating pulley A14 is used to drive the winding rod 13 to rotate, thereby improving the stability of the overshot net A4 during the lifting process. By controlling the forward and reverse rotation of the motor 23, the rotation direction of the winding rod 13 can be changed, thereby controlling the winding rod 13 to reel in or lower the traction rope 3.
[0027] Combined with attachment Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, both sides of the top of the overshot net A4 are fixedly connected to the limit frames 5, and the limit frames 5 are rotatably connected to the mounting rods 51. The mounting rods 51 are fixedly connected to the end of the overshot net A4 close to the baffle 52. The baffles 52 are all fan-shaped structures. A gap is set between the two baffles 52. The gap between the baffles 52 is smaller than the diameter of the float. The baffles 52 of the fan-shaped structure can complete the opening and closing work more quickly, so that the top opening of the overshot net A4 can complete the opening and closing state more quickly, and the single float can be salvaged more stably. The baffles 52 are all located above the overshot net A4. A connecting rod 6 is rotatably connected in the mounting rod 51. The bottom end of the connecting rod 6 is rotatably connected to the transmission rod 61. The bottom ends of the two transmission rods 61 are connected. A loading tray 62 is rotatably connected, and a number of counterweights 63 are placed in the loading tray 62. The counterweights 63 have a certain weight. According to the height position of the required salvage float, a certain amount of counterweights 63 are loaded into the loading tray 62 to increase the weight of the loading tray 62. When the loading tray 62 is stationary in the density gradient column, the increased weight of the counterweights 63 can cause the loading tray 62 to slowly sink, thereby slowly closing the baffle 52. During this process, the float to be salvaged is loaded into the overshot net A4, and then the overshot net A4 is lifted. At this time, the resistance of the liquid on the top of the loading tray 62 and the weight of the loading tray 62 itself can quickly close the baffle 52. The top of the loading tray 62 is threadedly connected to a sealing cover 64.
[0028] Furthermore, according to the required height of the salvage float, the sealing cover 64 is opened, and then an appropriate amount of counterweights 63 are placed in the loading tray 62. Then, the sealing cover 64 is closed, and the overshot net A4 is placed in the density gradient column. During the descent of the overshot net A4, the bottom of the loading tray 62 is relatively wide, and the contact surface with the liquid in the density gradient column is large, so that the loading tray 62 will encounter greater resistance as it follows the descent of the overshot net A4. At this time, the loading tray 62 will move upward due to the resistance, and the loading tray 62 will drive the transmission rods 61 on both sides thereof to move upward together. At this time, the upwardly moved transmission rod 61 cooperates with the connecting rod 6 to push the baffle 52 upward, and the top of the overshot net A4 is now open. In the open state, when the overshot net A4 moves to the bottom of the desired salvage float, the overshot net A4 is controlled to rise. At this time, the float will enter the overshot net A4 through the top opening of the overshot net A4. As the overshot net A4 continues to rise, the top of the loading tray 62 will be subjected to the resistance of the liquid. At the same time, with the weight of the counterweight plate 63 in the loading tray 62, the loading tray 62 can be quickly lowered. During the lowering process of the loading tray 62, the transmission rod 61 and the connecting rod 6 can be used to cooperate to lower the baffle 52, and the baffle 52 is used to block the top two sides of the overshot net A4. At this time, when the overshot net A4 passes the float above, the baffle 52 will be used to squeeze the float away, thereby completing the salvage work of only a single float.
[0029] When multiple floats and samples are salvaged simultaneously, multiple operations are required to salvage them using the overshot net A4, which can easily reduce the salvage efficiency. Figure 2 As shown, a further embodiment of the present invention is shown: when multiple floats are salvaged, the overshot net A4 is replaced with the overshot net B41. The diameter of the overshot net B41 is the same as that of the overshot net A4, but the height and depth of the overshot net B41 are greater than those of the overshot net A4. When all the floats and samples in the density gradient column are salvaged, the overshot net B41 is sunk to the bottom of the density gradient column and is located directly below the floats. The reeling rod 13 is then used to reel in the traction rope 3 to raise the overshot net B41. During the rising process of the overshot net B41, each float and sample can be salvaged from bottom to top until the overshot net B41 is removed from the density gradient column. At this time, all the floats and samples in the density gradient column are arranged in the overshot net B41 in the order in which they were in the density gradient column. After that, all the floats and samples can be removed from the overshot net B41.
[0030] Working principle: First, according to the height of the required salvage float, the sealing cover 64 is opened, and then an appropriate amount of counterweights 63 are placed in the loading tray 62, and then the sealing cover 64 is closed. In the process of salvaging a single float, the support frame 1 is placed outside the density gradient column, and the motor 23 is started to drive the pulley B21 to rotate. At this time, the pulley B21 can drive the pulley A14 to rotate through the transmission belt 22, and the rotating pulley A14 drives the winding rod 13 to rotate. At this time, the winding rod 13 can lower the traction rope 3, so that the overshot net A4 enters the density gradient column. As the overshot net A4 descends, according to the height of the required salvage float, the overshot net A4 is lowered to a position below the float, and then the overshot net A4 is controlled by the traction rope 3 to move directly below the float.
[0031] During this process, the bottom of the loading tray 62 is relatively wide, and the contact surface with the liquid in the density gradient column is large. As a result, the loading tray 62 encounters greater resistance as it descends with the overshot net A4. Due to this resistance, the loading tray 62 moves upward, driving the transmission rods 61 on both sides of it to move upward together. At this time, the upwardly moving transmission rods 61 cooperate with the connecting rod 6 to push the baffle 52 upward, and the top of the overshot net A4 is now open.
[0032] Then, the motor 23 is controlled to rotate in the opposite direction, and the pulley B21, the transmission belt 22 and the pulley A14 cooperate with each other to drive the reeling rod 13 to rotate in the opposite direction, and the reeling rod 13 is used to reel in the traction rope 3, so that the overshot net A4 begins to rise. During the rising process of the overshot net A4, the float located on it can be loaded into the overshot net A4. As the overshot net A4 continues to rise, the top of the loading tray 62 will be subjected to the resistance of the liquid. At the same time, with the weight of the counterweight plate 63 in the loading tray 62, the loading tray 62 can be quickly lowered. During the lowering process of the loading tray 62, the transmission rod 61 and the connecting rod 6 can be used to cooperate to lower the baffle 52, and the baffle 52 is used to block the top two sides of the overshot net A4. At this time, when the overshot net A4 passes the float above, the baffle 52 will squeeze the float apart, thereby completing the salvage work of only a single float.
[0033] When multiple floats are salvaged, the overshot net A4 is replaced with the overshot net B41. The diameter of the overshot net B41 is the same as that of the overshot net A4, but the height and depth of the overshot net B41 are greater than those of the overshot net A4. When all the floats and samples in the density gradient column are salvaged, the overshot net B41 is sunk to the bottom of the density gradient column and is located directly below the floats. The reeling rod 13 is then used to reel in the traction rope 3 to raise the overshot net B41. During the rising process of the overshot net B41, each float and sample can be salvaged from bottom to top until the overshot net B41 is removed from the density gradient column. At this time, all the floats and samples in the density gradient column are arranged in the overshot net B41 in the order in which they were in the density gradient column. Then, all the floats and samples can be taken out of the overshot net B41.
