Description

Technical Field

[0001] This utility model relates to the field of water level measurement equipment technology, and in particular to a water level measurement device. Background Technology

[0002] In hydrogeological surveys, groundwater level monitoring is a crucial task, and water level measuring devices are the key tools for accomplishing this task.

[0003] Among the many common water level measuring devices, a combination device is particularly practical. It mainly consists of a spool, a graduated rope, and a water sensor fixed to the end of the graduated rope. In actual operation, the user holds the spool firmly and then slowly rotates it. As the spool rotates, the graduated rope gradually descends along the pre-drilled water level hole. The water sensor at the end of the graduated rope also moves downwards. When the water sensor finally contacts the groundwater level, its built-in sensing element immediately captures this crucial information and quickly transmits the signal to the alarm installed on the surface of the measuring device. The alarm then emits a clear beep or illuminates a warning light to signal the user. At this point, the user only needs to stop rotating the spool, carefully observe and read the scale value on the graduated rope corresponding to the water level hole, and can accurately determine the depth of the groundwater level. This water level measuring device is simple to operate and intuitive, providing great convenience for groundwater level monitoring in hydrogeological surveys.

[0004] However, some current water level measuring devices have obvious inconveniences in operation. When lowering the scale rope, the user needs to manually and slowly rotate the spool, and the water sensor is gradually lowered along the pre-drilled water level hole. This operation is not only cumbersome, but if the user rotates the spool faster than the actual lowering speed of the water sensor, the scale rope is very likely to get tangled. This tangling will disrupt the normal line laying rhythm, increase the difficulty of operation, and thus seriously affect the efficiency and accuracy of the entire line laying work. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: a water level measuring device, comprising a frame, a spool rotatably mounted on the surface of the frame, a graduated rope wound around the surface of the spool, one end of the graduated rope being fixedly connected to the spool, and the other end of the graduated rope being fixedly connected to a water level sensor, a damping mechanism being connected to the surface of the frame via a support rod, the shaft end of the spool being located inside the damping mechanism, a transmission cylinder being fixedly connected to the shaft surface of the spool, a traction mechanism and a support frame being fixedly connected to the surface of the frame, a transmission belt being sleeved on the wheel surface of the transmission cylinder and the traction mechanism, and the graduated rope passing through the annular portion of the traction mechanism and the support frame.

[0006] As an improvement to the above technical solution, the damping mechanism includes a fixed frame, a threaded rod, a movable plate, a sliding rod, a spring, a pressing block, and a rubber pad. The fixed frame is connected to the surface of the frame via a support rod. A threaded rod is threadedly connected to the upper end of the fixed frame. A movable plate is rotatably connected to the lower end of the threaded rod. A spring is fixedly connected to the lower end of the movable plate. A pressing block is fixedly connected to the lower end of the spring. A rubber pad is provided at the lower end of the pressing block. The rubber pad is in contact with the shaft surface of the spool. Two sliding rods are fixedly connected to the upper end of the pressing block. The sliding rods pass through the movable plate and the fixed frame, and are slidably connected to the movable plate and the fixed frame.

[0007] As an improvement to the above technical solution, the traction mechanism includes a support plate, a limiting rod, a reciprocating threaded rod, a moving block, a traction ring, and a transmission wheel. Two support plates are fixedly connected to the surface of the frame, and a limiting rod is fixedly connected between the two support plates. A transmission wheel is rotatably connected to the end face of the support plate. A transmission belt is sleeved on the surface of the transmission wheel and the transmission cylinder. A reciprocating threaded rod is fixedly connected to the shaft end of the transmission wheel. One end of the reciprocating threaded rod is rotatably connected to the support plate. A moving block is threadedly connected to the surface of the reciprocating threaded rod. The limiting rod passes through the moving block and is slidably connected to the moving block. A traction ring is fixedly connected to the upper end of the moving block, and a graduated rope passes through the traction ring.

[0008] As an improvement to the above technical solution, the support frame includes a support inclined plate and a fixing ring. Two support inclined plates are fixedly connected to the surface of the frame body, and a fixing ring is fixedly connected between the two support inclined plates. The scale rope passes through the fixing ring.

[0009] As an improvement to the above technical solution, a fixing frame is fixedly connected to the upper end of the frame.

[0010] The beneficial effects of this utility model are as follows: By setting up a damping mechanism, the user only needs to turn its knob to easily adjust the damping effect of the damping mechanism on the line drum, thereby achieving precise control of the lowering speed of the water level sensor. This design not only eliminates the tedious operation of manually shaking the line drum to lower the line, but also significantly improves the stability and reliability of the lowering process of the water level sensor.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0016] Please see Figure 1-3 This utility model provides a technical solution: a water level measuring device, including a frame 1, a spool 2 rotatably mounted on the surface of the frame 1, a graduated rope 3 wound around the surface of the spool 2, one end of the graduated rope 3 being fixedly connected to the spool 2, and the other end of the graduated rope 3 being fixedly connected to a water level sensor 4, a damping mechanism 5 being connected to the surface of the frame 1 via a support rod, the shaft end of the spool 2 being located inside the damping mechanism 5, a transmission cylinder 7 being fixedly connected to the shaft surface of the spool 2, a traction mechanism 6 and a support frame 8 being fixedly connected to the surface of the frame 1, a transmission belt being sleeved on the wheel surface of the transmission cylinder 7 and the traction mechanism 6, and the graduated rope 3 passing through the loop portion of the traction mechanism 6 and the support frame 8.

[0017] In this implementation scheme, when carrying out the line laying operation, the user needs to rotate the knob of the damping mechanism 5 with a relatively gentle movement. As the knob is rotated, the damping effect of the damping mechanism 5 on the line drum 2 will gradually and smoothly decrease. During this process, the water level sensor 4 will slowly and steadily be lowered by its own weight.

[0018] At the same time, the spool 2 rotates due to traction, which in turn drives the transmission spool 7 to rotate synchronously. The transmission spool 7 is connected to the rotating part of the traction mechanism 6 through the transmission belt, thereby driving the rotating part to start running. The operation of the rotating part causes the ring body connected to it to move back and forth. Under the traction of the ring body, the scale rope 3 is released evenly and orderly, and slowly lowered along the ring part of the support frame 8.

[0019] When the water level sensor 4 touches the groundwater surface, it immediately transmits a signal to the onshore equipment. (The probe of the water level sensor 4 is made of stainless steel and has a water resistance contact point installed inside. The scale rope 3 is made of a steel ruler and a wire combined with plastic. When the contact point touches the water surface, it connects to the external signal receiving system on shore through the scale rope 3. When the probe's contact point touches the water surface, the receiver's speaker will emit a continuous buzzing sound. The working principle of the water level sensor 4 is a well-known principle of water level gauges and will not be elaborated here.) At this time, the user needs to rotate the knob of the damping mechanism 5 in the opposite direction to enhance the damping effect of the damping mechanism 5 on the reel 2, thereby effectively locking the reel 2. Subsequently, the user only needs to read the lowering scale on the scale rope 3 to accurately determine the depth of the groundwater level. Note: Components that directly contact the scale rope 3, such as the manually cranked reel 2, the traction ring 65, and the fixing ring 82, are all made of insulating material to avoid affecting signal transmission.

[0020] If the user needs to perform the winding operation, the user must first turn the knob of the damping mechanism 5 to release the damping restriction of the damping mechanism 5 on the spool 2. Then, turn the handle of the spool 2 to start the winding operation. During the winding process, the transmission drum 7 will also rotate due to the rotation of the spool 2, and drive the rotating part of the traction mechanism 6 through the transmission belt, thereby driving the ring body to move back and forth. Under the traction of the ring body, the graduated rope 3 can be evenly and tightly wound around the surface of the spool 2.

[0021] As can be seen, by setting up the damping mechanism 5, the user only needs to turn its knob to easily adjust the damping effect of the damping mechanism 5 on the line drum 2, thereby achieving precise control of the lowering speed of the water level sensor 4. This design not only eliminates the tedious operation of manually shaking the line drum 2 to lower the line, but also significantly improves the stability and reliability of the lowering process of the water level sensor 4.

[0022] like Figure 3 As shown, the damping mechanism 5 includes a fixed frame 51, a threaded rod 52, a movable plate 53, a sliding rod 54, a spring 55, a pressing block 56, and a rubber pad 57. The fixed frame 51 is connected to the surface of the frame 1 via a support rod. The upper end of the fixed frame 51 is threadedly connected to the threaded rod 52, which passes through it. The lower end of the threaded rod 52 is rotatably connected to the movable plate 53. The lower end of the movable plate 53 is fixedly connected to the spring 55. The lower end of the spring 55 is fixedly connected to the pressing block 56. The lower end of the pressing block 56 is provided with a rubber pad 57, which is in contact with the shaft surface of the spool 2. The upper end of the pressing block 56 is fixedly connected to two sliding rods 54. The sliding rods 54 pass through the movable plate 53 and the fixed frame 51, and are slidably connected to the movable plate 53 and the fixed frame 51.

[0023] In this embodiment, the user rotates the knob of the threaded rod 52, causing the threaded rod 52 to move downwards. This causes the moving plate 53 to slide downwards on the surface of the sliding rod 54, thereby compressing the spring 55. The elastic force of the spring 55 is transmitted to the compression block 56. The compression block 56 compresses the shaft end of the spool 2 through the rubber pad 57, thereby increasing the damping effect on the spool 2 and reducing the lowering speed of the water level sensor 4. Similarly, the user rotates the knob of the threaded rod 52 in the opposite direction, thereby reducing the compression force on the spring 55, and thus reducing the elastic force of the spring 55. This reduces the compression effect of the rubber pad 57 on the shaft end of the spool 2, thereby increasing the lowering speed of the water level sensor 4. Thus, the lowering speed of the water level sensor 4 can be controlled by adjusting the damping effect on the spool 2.

[0024] like Figure 2 As shown, the traction mechanism 6 includes a support plate 61, a limiting rod 62, a reciprocating threaded rod 63, a moving block 64, a traction ring 65, and a transmission wheel 66. Two support plates 61 are fixedly connected to the surface of the frame 1, and a limiting rod 62 is fixedly connected between the two support plates 61. A transmission wheel 66 is rotatably connected to the end face of the support plate 61. A transmission belt is sleeved on the surface of the transmission wheel 66 and the transmission cylinder 7. A reciprocating threaded rod 63 is fixedly connected to the shaft end of the transmission wheel 66. One end of the reciprocating threaded rod 63 is rotatably connected to the support plate 61. A moving block 64 is threadedly connected to the surface of the reciprocating threaded rod 63. The limiting rod 62 passes through the moving block 64 and is slidably connected to the moving block 64. A traction ring 65 is fixedly connected to the upper end of the moving block 64, and a scale rope 3 passes through the traction ring 65.

[0025] In this embodiment, when reeling in the line, the user rotates the handle of the spool 2, causing the spool 2 to rotate. As the spool 2 rotates, the graduated rope 3 can be reeled in. At the same time, the transmission spool 7 rotates synchronously. The transmission spool 7 drives the transmission wheel 66 to rotate via the transmission belt, which in turn drives the reciprocating threaded rod 63 to rotate. The reciprocating threaded rod 63 drives the moving block 64 to move back and forth. Thus, under the traction of the traction ring 65, the graduated rope 3 is evenly wound around the surface of the spool 2.

[0026] like Figure 2 As shown, the support frame 8 includes a support inclined plate 81 and a fixing ring 82. Two support inclined plates 81 are fixedly connected to the surface of the frame body 1, and a fixing ring 82 is fixedly connected between the two support inclined plates 81. The scale rope 3 passes through the fixing ring 82.

[0027] In this embodiment, when the scale rope 3 slides inside the fixed ring 82, the cooperation between the supporting inclined plate 81 and the fixed ring 82 can guide the scale rope 3. During the lowering and retrieval process, the limiting effect of the fixed ring 82 and the guiding effect of the supporting inclined plate 81 can reduce the occurrence of the scale rope 3 colliding with the inner wall of the water level hole, thereby protecting the scale on the scale rope 3 and improving the service life of the scale rope 3.

[0028] like Figure 1 As shown, a fixed frame 9 is fixedly connected to the upper end of the frame 1.

[0029] In this embodiment, the user can lift the entire device by lifting the fixed frame 9, which makes it easy for the user to move the entire device.

[0030] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
