Description

Technical Field

[0001] This utility model belongs to the technical field of closed-type current measuring cableway, and in particular relates to a direction fixing device for the lead weight of a closed-type current measuring cableway. Background Technology

[0002] A closed-type flow measurement cableway is an equipment system used for river flow measurement. The lead weight is an important component of it. It is usually a fish-shaped weight that is suspended on the cableway to carry instruments such as flow meters into the water for measurement. The lead weight orientation fixing device is mainly to ensure that the lead weight can be stably placed in the water in a predetermined direction.

[0003] In existing closed-type current measurement cableway lead weights, most are lowered using a single cable. However, a single cable may cause the lead weight to rotate during lowering, making it impossible to fix the lowering position of the lead weight and potentially leading to instability in the water, as illustrated by the Chinese utility model patent "Closed-type Vertical Cruise Ship Puller Cableway" (Publication No. CN2851228Y). Therefore, we propose a direction fixing device for closed-type current measurement cableway lead weights. Utility Model Content

[0004] The purpose of this invention is to provide a closed-type current measuring cable lead weight direction fixing device. The device uses a motor to drive a rotating shaft to rotate, which in turn drives gear one to rotate. Gear one then causes gear two to rotate in the opposite direction, thereby lowering cable one and cable two together. This solves the problem of instability of existing lead weights during the lowering process.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a closed-type current measuring cable lead weight direction fixing device, comprising a housing, an internal stabilizing cable-laying mechanism, and a fixing mechanism at the bottom of the housing. The stabilizing cable-laying mechanism includes two connecting strips. The front of each connecting strip is fixedly connected to the back of the housing, and a connecting plate is fixedly connected to the back of the connecting strip. A fixing circular frame is fixedly connected to the back of the connecting plate, and a motor is fixedly connected to the inner wall of the fixing circular frame. The bottom output shaft of the motor is fixedly connected to a rotating shaft via a coupling. The front of the rotating shaft penetrates the outer surface of the housing and extends into the interior. A gear one is fixedly connected to the outer surface of the rotating shaft, and a gear two meshes with the right side of the gear one. A driven shaft is fixedly connected to the inner wall of the gear two, and the front of the driven shaft penetrates the outer surface of the housing and extends into the interior. A first wire roller is fixedly connected to the outer surface of the housing. The first wire roller is located inside the housing. A first cable is fixedly connected to the outer surface of the first wire roller and is located inside the first wire roller. A cylinder is fixedly connected to the back of the connecting plate. The inner wall of the cylinder is rotatably connected to the outer surface of the driven shaft. A second wire roller is fixedly connected to the outer surface of the driven shaft and is located inside the housing. The rotating shaft drives the first gear to rotate, and then the first gear drives the second gear to rotate, so that the first gear and the second gear rotate in opposite directions. This allows the first cable and the second cable to be lowered together. The two cables keep the lead weight stable during the lowering process, making it easier for the lead weight to enter the water. This achieves the effect of fixing the trajectory of the lead weight and fixing its direction in the water, enabling more accurate measurement of the water flow speed.

[0007] Furthermore, a rotating disk is fixedly connected to the side of the driven shaft away from the cylinder, and a circular groove is provided inside the housing. The inner wall of the circular groove is rotatably connected to the outer surface of the rotating disk. By connecting the circular groove to the rotating disk, the driven shaft is stabilized and rotates within the device.

[0008] Furthermore, a second cable is fixedly connected to the outer surface of the second roller, and the second cable is disposed inside the second roller. A second rotating disk is fixedly connected to the side of the rotating shaft away from the motor. By connecting the rotating shaft to the second rotating disk, the rotating shaft can drive the second rotating disk to rotate.

[0009] Furthermore, a circular groove is provided inside the housing, and the inner wall of the circular groove is rotatably connected to the outer surface of the rotating disk. By connecting the circular groove to the rotating disk, the rotating shaft can be made to rotate stably inside the device.

[0010] Furthermore, the fixing mechanism includes a fixing plate fixedly connected to the end of the cable one away from the first roller, the top of the fixing plate being fixedly connected to the end of the cable two away from the second roller, and a connecting rod one being fixedly connected to the bottom of the fixing plate. By connecting the fixing plate and the connecting rod one, the effect of the fixing plate pushing the connecting rod one is achieved.

[0011] Furthermore, there are two connecting rods in total. Connecting rod two is fixedly connected to the bottom of the fixed plate, and connecting block one is fixedly connected to the side of connecting rod one away from the fixed plate. A lead weight is fixedly connected to the bottom of connecting block one. By connecting block one and the lead weight, the lead weight can be moved.

[0012] Furthermore, a connecting block two is fixedly connected to the side of the connecting rod two away from the fixed plate. The bottom of the connecting block two is fixedly connected to the top of the lead fish. By connecting the connecting rod two to the connecting block two, the effect of making the lead fish move stably is achieved.

[0013] Furthermore, a speed sensor is fixedly connected to the inner wall of the lead fish, a diverter block is fixedly connected to the bottom of the lead fish, and fins are fixedly connected to both the front and back of the lead fish. By pushing the fixing plate with cables one and two, the lead fish can be smoothly placed into the water flow. Since connecting rod one and connecting rod two form a triangle, the lead fish has a certain stability in the water. Then, the diverter block at the bottom of the lead fish can break the water, allowing the lead fish to enter the water more smoothly. This achieves the effect of diverting the water flow, making it easier for the lead fish to enter the water. Then, connecting rod one and connecting rod two maintain the stability of the lead fish in the water.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model incorporates a gear 1. The motor causes the rotating shaft to rotate, which in turn drives gear 1 to rotate. Gear 1 then drives gear 2 to rotate, which in turn drives the driven shaft to rotate. As the rotating shaft rotates, it also drives rotating disk 2 to rotate within the circular groove 2. Simultaneously, the rotating shaft causes the wire roller 1 to rotate, thus lowering cable 1. The rotating shaft drives gear 1 to rotate, which in turn drives gear 2 to rotate in opposite directions. This allows cable 1 and cable 2 to be lowered together. The combined weight of the cables keeps the lead weight stable during descent, facilitating its entry into the water more smoothly. This design achieves the effect of fixing the trajectory of the lead weight and its direction in the water, enabling more accurate measurement of water flow velocity.

[0016] 2. This utility model incorporates a fixing plate that causes connecting rod one and connecting rod two to move downwards. This, in turn, causes connecting rod one and connecting rod two to move the lead weight downwards via connecting blocks one and two. The diverting block below the lead weight then contacts the water surface first, breaking up the water flow, allowing the lead weight to enter the water. The fins on both sides of the lead weight help maintain its stability. The pushing action of cables one and two on the fixing plate ensures the lead weight is smoothly placed into the water. Because connecting rod one and connecting rod two form a triangle, the lead weight has a certain degree of stability in the water. The diverting block at the bottom of the lead weight breaks up the water, allowing the lead weight to enter the water more smoothly. This design achieves the effect of diverting the water flow, making it easier for the lead weight to enter the water, and the connecting rods one and two maintain the lead weight's stability in the water.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A connecting plate 210 is fixedly connected to the back of the connecting bar 209, and a fixing circular frame 201 is fixedly connected to the back of the connecting plate 210. The motor 202 is fixedly connected to the inner wall of the fixing circular frame 201. The fixing circular frame 201 connects to the motor 202, preventing the motor 202 from generating its own... The bottom output shaft of motor 202 is fixedly connected to a rotating shaft 203 via a coupling. The front of rotating shaft 203 penetrates the outer surface of housing 101 and extends into the interior. Gear 1 204 is fixedly connected to the outer surface of rotating shaft 203. Gear 225 meshes with gear 204 on its right side. Motor 202 connects to rotating shaft 203, causing rotating shaft 203 to rotate, thereby rotating gear 1 204.

The first cable 208 is fixedly connected to the outer surface of the first roller 207 and is located inside the first roller 207. A cylinder 211 is fixedly connected to the back of the connecting plate 210. The inner wall of the cylinder 211 is rotatably connected to the outer surface of the driven shaft 206. The cylinder 211 is connected to the connecting plate 210, and then the driven shaft 206 will rotate inside the cylinder 211, so that the driven shaft 206 can rotate stably. A second roller 212 is fixedly connected to the outer surface of the driven shaft 206 and is located inside the housing 101. The driven shaft 206 is located away from the cylinder 211. A rotating disk 214 is fixedly connected to the side. A circular groove 213 is opened inside the housing 101. The rotating disk 214 is connected to the rotating disk 214 through a driven shaft 206.

The cable 215 is set inside the roller 212. A rotating disk 216 is fixedly connected to the side of the rotating shaft 203 away from the motor 202. The cable 215 is connected to the driven shaft 206. The driven shaft 206 will drive the cable 215 to rotate, so that the cable 215 can be lowered.

[0029] The motor 202 can be started, which will cause the rotating shaft 203 to rotate. The rotating shaft 203 will then drive the gear 1 204 to rotate, which in turn drives the gear 2 205 to rotate. Then the rotating shaft 203 and the driven shaft 206 will drive the roller 1 207 and the roller 2 212 to rotate, thereby moving the lead fish 306.

[0030] The housing 101 has a circular groove 217 inside, and the inner wall of the circular groove 217 is rotatably connected to the outer surface of the rotating disk 216. The fixing mechanism 3 includes a fixing plate 301 fixedly connected to the end of the cable 208 away from the roller 207. The top of the fixing plate 301 is fixedly connected to the end of the cable 215 away from the roller 212. The rotating disk 216 is connected through the circular groove 217, and the rotating disk 216 will rotate within the circular groove 217, thereby enabling the rotating shaft 203 to rotate stably.

The connecting block 304 is fixedly connected to the side of the connecting rod 302 away from the fixed plate 301. The bottom of the connecting block 304 is fixedly connected to the lead weight 306. The fixed plate 301 connects to the connecting rod 302. Then the fixed plate 301 will drive the connecting rod 302 to move together, thereby moving the lead weight 306.

[0031] When the motor 202 drives the rotating shaft 203 to rotate, the rotating shaft 203 will also drive the rotating disk 216 to rotate in the circular groove 217, so that the rotating shaft 203 rotates stably in the device. Then, the cable 1 208 and the cable 2 215 will first lower the fixing plate 301, so that the lead fish 306 can move and enter the water.

[0032] Connecting block 305 is fixedly connected to the side of connecting rod 303 away from fixing plate 301. The bottom of connecting block 305 is fixedly connected to the top of lead fish 306.

Speed ​​sensor 307 is connected through lead fish 306, and then speed sensor 307 will detect water speed inside lead fish 306.

[0033] When the fixed plate 301 moves downward, it will drive the connecting rod 1 302 and the connecting rod 2 303 to move downward together. Then the connecting rod 1 302 will drive the connecting block 1 304 to move downward, and at the same time the connecting rod 2 303 will also drive the connecting block 2 305 to move downward. Then the connecting blocks 1 304 and the connecting blocks 2 305 will cause the lead weight 306 to move downward, so that the lead weight 306 enters the water stably.

[0034] One specific application of this embodiment is:

[0035] When the equipment is needed, the worker first places the lead weight 306 into the water via the stabilizing line-laying mechanism 2. Then, the motor 202 is started, causing the rotating shaft 203 to rotate. This rotating shaft 203 then drives gear one 204 to rotate, which in turn drives gear two 205 to rotate. Gear two 205 then drives the driven shaft 206 to rotate. As the rotating shaft 203 rotates, it also drives the rotating disk two 216 to rotate within the circular groove two 217. Simultaneously, the rotating shaft 203 also causes the line roller one 207 to rotate, thus lowering the cable one 208. Because gear one 204 and gear two 205 are meshed together, gear two 205 will... The driven shaft 206 rotates in the opposite direction to gear 204, causing the driven shaft 206 to rotate the rotating disk 214 within the circular groove 213. Simultaneously, the driven shaft 206 also drives the line roller 212 to rotate, thus lowering the cable 215. The rotating shaft 203 then drives gear 204 to rotate, which in turn drives gear 205 to rotate in opposite directions. This allows cable 208 and cable 215 to be lowered together. The weight of the two cables stabilizes the sinker 306 during descent, facilitating its entry into the water and ensuring a smoother lowering process. The trajectory of the lead weight 306 is fixed, thus fixing its direction in the water and enabling more accurate measurement of water flow velocity. The lead weight 306 is then placed stably in the water using the fixing mechanism 3. As cables 208 and 215 move downwards, the fixing plate 301 also moves downwards. This causes connecting rods 302 and 303 to move downwards, which in turn, through connecting blocks 304 and 305, move the lead weight 306 downwards. The diverting block 308 below the lead weight 306 then contacts the water surface first, breaking up the water flow before the lead weight 306 enters the water. The fins 309 on both sides of the lead weight 306 also help keep the lead weight 306 stable. Finally, the speed sensor 307 measures the water flow speed. Through the push of the fixing plate 301 by cable 1 208 and cable 2 215, the lead weight 306 can be smoothly put into the water flow. Since the connecting rod 1 302 and connecting rod 2 303 form a triangle, the lead weight 306 has a certain stability in the water. Then, the diverting block 308 at the bottom of the lead weight 306 can break the water, allowing the lead weight 306 to enter the water more smoothly. This achieves the effect of diverting the water flow, allowing the lead weight 306 to enter the water more smoothly. Then, the connecting rod 1 302 and connecting rod 2 303 keep the lead weight 306 stable in the water.
