Description

Technical Field

[0001] This utility model relates to the field of submersible pump depth measurement technology, specifically a depth measurement device for submersible pumps. Background Technology

[0002] When groundwater monitoring wells are built, the specific location of the filter pipes for the monitoring strata is marked. Most monitoring wells have filter pipes located somewhere between 100 and 600 meters underground. When collecting water samples in the monitoring well, the submersible pump needs to be lowered at a constant speed to the location of the filter pipe to avoid collision with the well wall and to ensure that the submersible pump can collect natural groundwater from the monitoring strata. In actual work, an effective measurement tool is needed to lower the submersible pump at a constant speed to the target filter pipe location. Currently, there are few tools for measuring the depth of the submersible pump at any location underground, and existing tools are difficult to use for measuring depths of several hundred meters, so their advantages are not very obvious.

[0003] The tool used to measure the burial depth of a well is a steel tape level gauge, while the tool used to measure the depth of a well is a well depth gauge. There is no dedicated tool for measuring the depth of a submersible pump well. The working principle of a steel tape level gauge is: when the probe touches the water surface, it triggers an alarm, at which point the water depth value on the tape can be read. The working principle of a well depth gauge is: when the probe touches the bottom of the well, it triggers an alarm, at which point the well depth value on the tape can be read. Based on the working principles of these two instruments, neither can be used to measure the depth of a submersible pump well.

[0004] First, consider adding a measuring rope to be attached to the submersible pump, and lowering it at a constant speed to the target filter pipe location. While the measuring rope can accurately place the submersible pump in the target position, the standard measuring rope length is 100 meters, requiring a custom-made rope of a specific length. The submersible pump is already attached to a nylon rope and a drain pipe; attaching another measuring rope would make the work more cumbersome, and deploying and retrieving several hundred meters of measuring rope would be troublesome, increasing the workload.

[0005] Secondly, consider marking the length on the nylon rope or drain pipe used to secure the submersible pump. However, when lowering and raising the submersible pump, the length markings are easily worn off when the nylon rope is held under stress. The markings on the drain pipe are also easily worn off when the pipe is submerged in water for a long time, and the drain pipe cannot be fully straightened in the well.

[0006] The above two considerations do not offer significant advantages when calculating the depth of submersible pump wells. Therefore, based on the working process and actual needs, a depth calculation device for submersible pumps was designed. Utility Model Content

[0007] To address the existing technical problem of needing an effective measurement tool to uniformly lower a submersible pump to the target water filter pipe, this invention provides a depth measurement device for submersible pumps.

[0008] This utility model is achieved using the following technical solution: a depth measuring device for a submersible pump, comprising a submersible pump body and a nylon rope. One end of the submersible pump body is fixedly connected to one end of the nylon rope. The nylon rope is externally movably connected to a first movable end and a second movable end. A limit rope is fixedly connected between the first movable end and the second movable end. The first movable end includes a first hand sleeve and a first rope loop. The inner side of the first rope loop is fixedly connected to the first hand sleeve. A magnet is fixedly connected to one end of the first rope loop. The second movable end includes a second hand sleeve and a second rope loop. The inner side of the second rope loop is fixedly connected to the second hand sleeve. An iron plate is fixedly connected to one end of the second rope loop. One side of the magnet is magnetically connected to one side of the iron plate. A magnet sensor is provided on one side of the iron plate. A counter is electrically connected to one end of the magnet sensor.

[0009] Preferably, the inner side of the first hand sleeve is movably connected to the outside of the nylon rope, and the first rope loop is movably connected to the outside of the nylon rope.

[0010] Preferably, a first gripping block is fixedly connected to one side of the first rope loop, and the first gripping block is movably connected to the outside of the nylon rope.

[0011] Preferably, the inner side of the second hand sleeve is movably connected to the outside of the nylon rope, and the second rope loop is movably connected to the outside of the nylon rope.

[0012] Preferably, a second gripping block is fixedly connected to one side of the second rope loop, and the second gripping block is movably connected to the outside of the nylon rope.

[0013] Preferably, one end of the first rope loop is fixedly connected to a fixing block, one side of the fixing block is fixedly connected to one end of the limiting rope, one end of the second rope loop is fixedly connected to an automatic rope retractor, and the other end of the limiting rope is wound inside the automatic rope retractor.

[0014] Compared with the prior art, the beneficial effects of this utility model are: In use, this invention involves moving the first movable end to the point where the submersible pump body connects to the nylon rope, while the second movable end moves in the opposite direction until the nylon rope and the limiting rope are taut. After that, the second movable end remains stationary, and the first movable end is moved to one end of the second movable end until they connect. The counter then counts once. At this point, the first movable end remains stationary, and the second movable end is moved to taut the nylon rope and the limiting rope. Then, the first movable end is moved to contact the second movable end. This process is repeated to slowly lower the submersible pump body to the depth required for water intake. Finally, the depth of the submersible pump body in the well is calculated.

[0015] When in use, this device calculates the descent depth of the submersible pump body during the uniform descent process, while avoiding damage caused by collisions with the outside world due to excessively rapid retrieval. The numerical calculation is convenient and does not add extra workload; it has high applicability, and the length of the limiting rope can be adjusted according to the individual's arm span; the device is compact and easy to use and store.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] Example 1: Please refer to Figure 1 - Figure 3 This embodiment of a depth measuring device for a submersible pump includes a submersible pump body 1 and a nylon rope 2. One end of the submersible pump body 1 is fixedly connected to one end of the nylon rope 2. The nylon rope 2 is externally movably connected to a first movable end 3 and a second movable end 4. A limit rope 5 is fixedly connected between the first movable end 3 and the second movable end 4. The first movable end 3 includes a first hand sleeve 6 and a first rope loop 7. The inner side of the first rope loop 7 is fixedly connected to the first hand sleeve 6. A magnet 9 is fixedly connected to one end of the first rope loop 7. The second movable end 4 includes a second hand sleeve 10 and a second rope loop 11. The inner side of the second rope loop 11 is fixedly connected to the second hand sleeve 10. An iron plate 13 is fixedly connected to one end of the second rope loop 11. One side of the magnet 9 is magnetically connected to one side of the iron plate 13. A magnet sensor 14 is provided on one side of the iron plate 13. A counter 15 is electrically connected to one end of the magnet sensor 14. The length of the limiting rope 5 can be adjusted according to an individual's arm span, with 10 centimeters as the minimum adjustable length. The limiting rope 5 is set to 1.5 meters. Multiple marks are evenly spaced on the nylon rope 2, with a spacing of 10 centimeters between the marks. The counter 15 works as follows: the magnet 9 is a permanent magnet (such as a neodymium iron boron magnet), and the iron plate 3 is a low-carbon steel plate that can be magnetized. When the two moving ends come into contact, the magnet 9 and the iron plate 13 are attracted by magnetic force (magnetic connection), forming physical contact and triggering the nearby magnet sensor 14. The magnet sensor 14 is a Hall sensor (or magnetoresistive) that can sense sudden changes in magnetic field strength. When there is no contact, the magnet sensor 14 is in a no-magnetic-field (or weak-magnetic-field) environment and outputs a low-level signal. When the magnet 9 is close, the magnetic field strength increases sharply (exceeding the threshold), and the magnet sensor 14 outputs a high-level signal as the electrical signal source for counting triggering. The counter 15 has a built-in microcontroller and counting circuit, which is electrically connected to the magnet sensor 14 through a wire. It receives the level signal of the sensor in real time and sets "high level signal lasting ≥0.5 seconds" as an effective trigger (to avoid accidental touch). Each time an effective signal is received, the number on the display screen (15) automatically increments by 1 (the initial value is 0). In use, move the first moving end 3 to the position where the submersible pump body 1 is connected to the nylon rope 2, and move the second moving end 4 in the opposite direction until the nylon rope 2 and the limiting rope 5 are taut. Then, keep the second moving end 4 still and move the first moving end 3 to one end of the second moving end 4 so that the two are connected. The counter 15 will count once. At this time, keep the first moving end 3 still and move the second moving end 4 to make the nylon rope 2 and the limiting rope 5 taut. Then move the first moving end 3 to contact the second moving end 4. Repeat this action to slowly lower the submersible pump body 1 to the depth required for water intake. Then, when reading the value, the length of the limit rope 5 x the value of the counter 15 + the length of the submersible pump body 1 is the depth of the submersible pump body 1 in the well. Furthermore, the inner side of the first palm sleeve 6 is movably connected to the outside of the nylon rope 2, the first rope loop 7 is movably connected to the outside of the nylon rope 2, a first gripping block 8 is fixedly connected to one side of the first rope loop 7, the first gripping block 8 is movably connected to the outside of the nylon rope 2, the inner side of the second palm sleeve 10 is movably connected to the outside of the nylon rope 2, the second rope loop 11 is movably connected to the outside of the nylon rope 2, a second gripping block 12 is fixedly connected to one side of the second rope loop 11, and the second gripping block 12 is movably connected to the outside of the nylon rope 2. The first hand sleeve 6 and the second hand sleeve 10 have the same structure. Each hand sleeve has two drawstring loops at both ends. The first hand sleeve 6 has a magnet at one end, and the second hand sleeve 10 has a counter at one end. The first grip block 8 and the second grip block 12 are made of soft material and can be deformed. By gripping the first grip block 8, the first moving end 3 can be fixed. By gripping the second grip block 12, the second moving end 4 can be fixed. Furthermore, one end of the first rope loop 7 is fixedly connected to a fixing block 16, one side of the fixing block 16 is fixedly connected to one end of the limiting rope 5, one end of the second rope loop 11 is fixedly connected to an automatic rope retractor 17, the other end of the limiting rope 5 is wound inside the automatic rope retractor 17, one end of the first palm sleeve 6 is fixedly connected to one end of the limiting rope 5 through the fixing block 16, and the other end of the limiting rope 5 is retracted inside the fixing block 16; The automatic rope retractor 17 is existing technology. Its working principle is as follows: the rope is wound on the spool inside the automatic rope retractor 17. The spool surface has anti-slip textures or grooves to prevent the rope from loosening. The spring coil is installed inside the spool and is the key component that provides power for automatic retrieval. When the rope is pulled out, the spring coil is twisted and stores power. When the rope is released, the spring rebounds and drives the spool to reverse, so as to realize the automatic winding and retrieval of the rope. Secondly, after the first moving end 3 and the second moving end 4 are connected and counted, the first moving end 3 is fixed and the second moving end 4 is moved. The limiting rope 5 will be pulled out from the inside of the automatic rope retractor 17. When the first moving end 3 moves closer, the spring inside the automatic rope retractor 17 contracts and drives the limiting rope 5 to retract and wind.

[0020] Working principle: By moving the first moving end 3 to the connection position between the submersible pump body 1 and the nylon rope 2, the second moving end 4 moves in the opposite direction until the nylon rope 2 and the limiting rope 5 are taut. Then, the second moving end 4 remains stationary, and the first moving end 3 is moved to one end of the second moving end 4, where they connect. The counter 15 counts once. At this time, the first moving end 3 remains stationary, and the second moving end 4 is moved to taut the nylon rope 2 and the limiting rope 5. Then, the first moving end 3 is moved to contact the second moving end 4. This action is repeated to slowly lower the submersible pump body 1 to the depth required for water intake. This device calculates the lowering depth of the submersible pump body 1 while lowering it at a constant speed, and avoids damage caused by collisions with the outside world due to excessively rapid lowering and retraction. The numerical calculation is convenient and does not add extra workload. It has high applicability, and the length of the limiting rope 5 can be adjusted according to the individual's arm span. The device is compact and easy to use and store.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
