Description

Technical Field

[0001] This utility model relates to the field of water level detection, specifically to a vertical well water level gauge. Background Technology

[0002] The float level gauge is a common water level measuring device. As a classic water level measuring instrument, the float level gauge has a long history of application in the field of hydrological monitoring.

[0003] Existing float-type water level gauges, as described in patent application CN201410463936.8, include a water level encoder, a water level wheel, a suspension cable, a float, and a pressure wheel. When the float is immersed in water, it moves up and down accordingly when the water level fluctuates. The float then moves the suspension cable, and the water level encoder detects this movement to determine the water level change within the shaft. However, in practical use, the length of the suspension cable needs to be adapted to the depth of the shaft to ensure the float can reach the water surface. This makes float-type water level gauges of the same specification unsuitable for shafts of different depths.

[0004] Therefore, how to adapt the float level gauge to vertical shafts of different depths is a technical problem that urgently needs to be solved. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a vertical shaft water level gauge to solve the technical problem that float water level gauges in the prior art are difficult to adapt to vertical shafts of different depths.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a vertical well water level gauge, which includes: support; A float assembly includes a first roller, a first suspension cable, and a float ball. The first roller is rotatably mounted on the bracket, and one end of the first suspension cable is wound around the first roller, while the other end is connected to the float ball. A counterweight assembly includes a second roller, a second suspension cable, and a counterweight. The second roller is rotatably mounted on the bracket. One end of the second suspension cable is wound around the second roller, and the other end is connected to the counterweight. The clutch has two ends that are respectively connected to the first roller and the second roller, and the clutch has a first state that establishes a transmission relationship between the first roller and the second roller, and a second state that disengages the first roller and the second roller from the transmission relationship.

[0007] In some embodiments, the clutch includes a first transmission part, a second transmission part, a third transmission part, and a base. The first transmission part and the second transmission part are coaxially connected to the first roller and the second roller, respectively. The third transmission part is rotatably mounted on the base. The base is movable relative to the bracket. By adjusting the base, the third transmission part can be connected to or disconnected from the first transmission part and the second transmission part, so that the clutch switches between the first state and the second state.

[0008] In some embodiments, the first transmission part includes a first gear, the second transmission part includes a second gear, and the third transmission part includes a third gear. The first gear is sleeved on the shaft of the first roller, the second gear is sleeved on the shaft of the second roller, and the third gear is rotatably mounted on the base. When the clutch is in the first state, the third gear meshes with the first gear and the second gear. When the clutch is in the second state, the third gear disengages from the first gear and the second gear.

[0009] In some embodiments, the bracket is provided with guide rails, and the base is slidably disposed on the guide rails.

[0010] In some embodiments, the bracket has a first screw hole and a second screw hole, and the base has a mating hole. A bolt passes through the mating hole and is screwed into the first screw hole to keep the clutch in the first state, and a bolt passes through the mating hole and is screwed into the second screw hole to keep the clutch in the second state.

[0011] In some embodiments, a first annular groove is formed on the outer periphery of the first roller, and one end of the first suspension cable is wound around and housed in the first annular groove. A second annular groove is formed on the outer periphery of the second roller, and one end of the second suspension cable is wound around and housed in the second annular groove.

[0012] In some embodiments, the buoy has a first shackle, and one end of the first suspension cable is attached to the first shackle.

[0013] In some embodiments, the counterweight includes a suspended basket and a plurality of counterweight blocks, one end of the second suspension cable is connected to the suspended basket, and the plurality of counterweight blocks are built into the suspended basket.

[0014] In some embodiments, the top of the suspended basket has a second lifting ring, and one end of the second suspension cable is tied to the second lifting ring.

[0015] In some embodiments, the bracket has a flange at each end.

[0016] Compared with the prior art, the vertical shaft water level gauge provided by this utility model has the following advantages: When installing a vertical shaft water level gauge, first fix the bracket to the top of the shaft. Adjust the clutch to the second position to release the first suspension cable until the float reaches the water surface. Then release the second suspension cable, suspending the counterweight inside the shaft. Adjusting the clutch to the first position then establishes a transmission relationship between the first and second rollers, balancing the weights of the first suspension cable, float, second suspension cable, and counterweight. The float's movement in response to water level changes within the shaft moves the first suspension cable (and the second suspension cable and counterweight), allowing the measurement of water level changes. Since the lengths of the lowered first and second suspension cables are adjustable, the gauge can accommodate shafts of varying depths, increasing its applicability. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] To address the technical problem that float-type water level gauges are difficult to adapt to vertical shafts of different depths, this utility model provides a vertical shaft water level gauge that, through adjustable length first and second suspension cables, can be adapted to vertical shafts of different depths, thus expanding the applicability of the vertical shaft water level gauge.

[0020] It should be noted that the vertical shaft water level gauge of this utility model is used for vertical shaft water level monitoring. For ease of explanation, this utility model will only be described in the context of the application of the vertical shaft water level gauge in a vertical shaft scenario.

[0021] Please see Figure 1 , Figure 1This is a schematic diagram of the structure of a vertical well water level gauge according to one embodiment of the present invention. The vertical well water level gauge includes a support 1, a float assembly 2, a counterweight assembly 3, and a clutch 4. The float assembly 2 includes a first roller 21, a first suspension cable 22, and a float 23. The first roller 21 is rotatably mounted on the support 1. One end of the first suspension cable 22 is wound around the first roller 21, and the other end is connected to the float 23. The counterweight assembly 3 includes a second roller 31, a second suspension cable 32, and a counterweight 33. The second roller 31 is rotatably mounted on the support 1. One end of the second suspension cable 32 is wound around the second roller 31, and the other end is connected to the counterweight 33. The clutch 4 is connected to the first roller 21 and the second roller 31 respectively. The clutch 4 has a first state that establishes a transmission relationship between the first roller 21 and the second roller 31, and a second state that disengages the transmission relationship between the first roller 21 and the second roller 31.

[0022] In this embodiment, when a vertical shaft water level gauge needs to be installed, the bracket 1 can be fixed to the top of the vertical shaft first. The clutch 4 is adjusted to the second state, releasing the first suspension cable 22 until the float 23 is lowered to the water surface. Then, the second suspension cable 32 is released, suspending the counterweight 33 inside the vertical shaft. At this point, adjusting the clutch 4 to the first state allows the first roller 21 and the second roller 31 to establish a transmission relationship, balancing the weights of the first suspension cable 22, float 23, second suspension cable 32, and counterweight 33. The float 23, as the water level changes within the vertical shaft, can move the first suspension cable 22 (second suspension cable 32 and counterweight 332), thus allowing the movement of the first suspension cable 22 (second suspension cable 32 and counterweight 332) to determine the water level change within the vertical shaft. Since the lengths of the lowered first suspension cable 22 and second suspension cable 32 are adjustable, it can adapt to vertical shafts of different depths, increasing the adaptability of the vertical shaft water level gauge.

[0023] In some embodiments, the clutch 4 includes a first transmission part 41, a second transmission part 42, a third transmission part 43, and a base 44. The first transmission part 41 and the second transmission part 42 are coaxially connected to the first roller 21 and the second roller 31, respectively. The third transmission part 43 is rotatably mounted on the base 44. The base 44 can move relative to the bracket 1. By adjusting the base 44, the third transmission part 43 can be connected to or disengaged from the first transmission part 41 and the second transmission part 42, so that the clutch 4 switches between a first state and a second state.

[0024] In the above embodiment, the movement of the base 44 relative to the support 1 drives the third transmission unit 43 to move synchronously, achieving precise docking or complete disengagement with the first transmission unit 41 and the second transmission unit 42, thereby switching between the two key stages of "establishing gravity balance" and "adjusting the suspension cable length". The coaxial connection design between the first transmission unit 41 and the first roller 21, and between the second transmission unit 42 and the second roller 31, minimizes eccentric loss and torque waste during power transmission, ensuring that the rotation of the first roller 21 can be completely and synchronously transmitted to the second roller 31 (or vice versa). When the float 23 undergoes a slight displacement due to water level changes, the transmission unit can quickly drive the counterweight 33 to move synchronously, improving the sensitivity of water level change feedback and making the monitoring data more real-time and accurate.

[0025] In some embodiments, the first transmission unit 41 includes a first gear 411, the second transmission unit 42 includes a second gear 421, and the third transmission unit 43 includes a third gear 431. The first gear 411 is sleeved on the shaft of the first roller 21, the second gear 421 is sleeved on the shaft of the second roller 31, and the third gear 431 is rotatably mounted on the base 44. When the clutch 4 is in the first state, the third gear 431 meshes with the first gear 411 and the second gear 421. When the clutch 4 is in the second state, the third gear 431 disengages from the first gear 411 and the second gear 421. The gear meshing transmission method has a fixed and precise transmission ratio, ensuring that the rotation angle and linear velocity of the first roller 21 and the second roller 31 are completely synchronized. When the float 23 moves the first suspension cable 22 due to the rise or fall of the water level, the second suspension cable 32 will also move the same distance synchronously, avoiding the imbalance of gravity caused by the unstable transmission ratio, ensuring the linear correspondence between water level changes and the amount of suspension cable movement, and improving the accuracy of water level monitoring.

[0026] In some embodiments, the bracket 1 is provided with a guide rail 11, and the base 44 is slidably disposed on the guide rail 11. The guide rail 11 provides a fixed trajectory for the movement of the base 44, ensuring that the base 44 always maintains a straight line during movement, avoiding lateral deviation or tilting, so that the third transmission part 43 can be accurately aligned with the first transmission part 41 and the second transmission part 42, ensuring that the teeth are completely aligned during meshing, and preventing problems such as tooth jamming or uneven wear, thus ensuring transmission stability and structural safety.

[0027] In some embodiments, the bracket 1 has a first screw hole 12 and a second screw hole 13, and the base 44 has a mating hole 441. A bolt passes through the mating hole 441 and is screwed into the first screw hole 12 to keep the clutch 4 in a first state. A bolt passes through the mating hole 441 and is screwed into the second screw hole 13 to keep the clutch 4 in a second state. By passing the bolt through the mating hole 441 of the base 44 and screwing it into the first screw hole 12 or the second screw hole 13 of the bracket 1, the base 44 can be firmly fixed in a designated position. The thread locking force of the bolt can effectively resist the influence of vibration, external impact, and other factors, and prevent the base 44 from moving accidentally, which could lead to erroneous switching of the clutch 4's state.

[0028] In some embodiments, the outer periphery of the first roller 21 is provided with a first annular groove 211, one end of the first suspension cable 22 is wound around and housed in the first annular groove 211, and the outer periphery of the second roller 31 is provided with a second annular groove 311, one end of the second suspension cable 32 is wound around and housed in the second annular groove 311.

[0029] The first annular groove 211 and the second annular groove 311 limit and protect the first suspension cable 22 and the second suspension cable 32, so that the first suspension cable 22 wound on the first roller 21 is hidden in the first annular groove 211, and the second suspension cable 32 wound on the second roller 31 is hidden in the second annular groove 311.

[0030] In some embodiments, the float 23 has a first lifting ring 231, and one end of the first suspension cable 22 is tied to the first lifting ring 231. After the first suspension cable 22 is connected to the first lifting ring 231 by tying or buckling, the stress point is concentrated and uniform, avoiding the risk of the suspension cable slipping due to the smooth surface and irregular shape of the float 23 when directly tying it. Especially when the float 23 is immersed in water for a long time and the suspension cable is damp and aged, the connection can still be maintained firmly, ensuring that the float 23 will not fall to the bottom of the shaft, avoiding equipment damage and monitoring interruption.

[0031] In some embodiments, the counterweight 33 includes a basket 331 and several counterweight blocks 332. One end of the second suspension cable 32 is connected to the basket 331, and the several counterweight blocks 332 are built into the basket 331. By increasing or decreasing the number of counterweight blocks 332 in the basket 331, the weight of the counterweight can be precisely adjusted, perfectly adapting to floats 23 of different specifications and vertical shafts of different depths (the greater the depth, the greater the weight of the suspension cable, and the more counterweight needs to be added accordingly). This solves the problem that traditional fixed-weight counterweights 33 cannot adapt to various scenarios, allowing the same water level gauge to be applied to vertical shafts of different depths, expanding the adaptability range by more than 80% and improving the product's versatility.

[0032] In some embodiments, the top of the suspended platform 331 has a second lifting ring 3311, and one end of the second suspension cable 32 is tied to the second lifting ring 3311. The second lifting ring 3311 is located directly above the geometric center of the suspended platform 331. After the suspension cable is connected, the weight of the counterweight 33 can be evenly distributed on the lifting ring and the structure of the suspended platform 331, avoiding tilting or deformation of the suspended platform 331 caused by force offset. This ensures that the counterweight 33 is vertically suspended in the shaft and will not collide or rub against the shaft wall, reducing the lateral tension of the suspension cable and ensuring the service life of the suspension cable and the suspended platform 331. At the same time, it avoids the imbalance of gravity caused by the tilting of the counterweight 33.

[0033] In some embodiments, the bracket 1 has a flange 14 at each end. The flange 14 is integrally formed with the bracket 1 or connected with high-strength bolts. The multiple bolt holes on the flange 14 can evenly fix the bracket 1 to the mounting surface at the top of the shaft (such as a concrete platform or steel structure frame). The fixing points are evenly distributed and the force is balanced, which can effectively resist the influence of external forces such as vibration, wind, and water flow impact in the shaft environment, ensuring that the bracket 1 is not loose or tilted after installation. Compared with the welding fixing method, disassembly is more convenient, and the fixing strength can be adjusted by the bolt preload to adapt to installation scenarios with different strength requirements.

[0034] To better understand this utility model, the following is combined with... Figures 1 to 2 The technical solution of this utility model is described in detail below: When installing a vertical shaft water level gauge, first fix bracket 1 to the top of the shaft. Adjust clutch 4 to the second state, releasing the first suspension cable 22 until the float 23 is lowered to the water surface. Then release the second suspension cable 32, suspending the counterweight 33 inside the shaft. Adjusting clutch 4 to the first state at this point allows the first and second rollers 21 to establish a transmission relationship, balancing the weights of the first suspension cable 22, float 23, second suspension cable 32, and counterweight 33. The float 23, as the water level changes within the shaft, moves the first suspension cable 22, allowing the movement of the first suspension cable 22 to determine the water level. Since the lengths of the lowered first and second suspension cables 22 are adjustable, the gauge can adapt to shafts of varying depths, increasing its applicability.

[0035] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
