Abstract

This utility model discloses a water level probe with an alarm function, including a measuring rod. A positioning sleeve is slidably connected to the surface of the measuring rod. The positioning sleeve has a height adjustment structure inside and an automatic reading structure on its surface. A water level alarm structure is provided at the bottom of the measuring rod. This utility model provides a water level probe with an alarm function. By setting up an automatic reading structure, when observing data, the distance to the positioning plate is first measured using a laser rangefinder. This is used as the first observation data. By rotating a knob in conjunction with a shaft, a friction wheel is driven to rotate. Simultaneously, the friction wheel rotates, allowing the measuring rod to slide up and down inside the positioning sleeve until the bottom of the probe contacts the water surface.

This effectively reduces the workload of operators and increases measurement accuracy.

Description

Technical Field

[0001] This utility model relates to the field of water level measuring needle technology, and in particular to a water level measuring needle with an alarm function. Background Technology

[0002] A water level probe is a water level measuring instrument consisting of a vertically movable measuring rod and a probe. It determines the water level height by measuring the force exerted by the water level on the probe and is typically used to accurately measure the position of the free surface of a liquid.

[0003] For example, Chinese Patent Publication No. (CN222617981 U) discloses a novel water level probe, which describes: "It includes a support base, the support base is provided with a sliding hole, the support base is slidably fitted onto the measuring rod through the sliding hole, at least three limiting lugs are evenly distributed in a ring on the outer wall of the support base, the support rod and the limiting lugs are hinged by a pin, the support base is also provided with a limiting screw hole, and the limiting screw is screwed into the limiting screw hole. This novel water level probe has a simple structure and is easy to store and carry."

[0004] In summary, the device also has the following technical problems: the water level probe currently used obtains water level change data by observing the difference between two water levels. Existing probes generally use mechanical positioning combined with human visual observation for data observation. The water level probe is usually installed at a low position, and the observer needs to lower their posture to observe. Even when lowering their posture, the observation is often done at an angle, which can lead to deviations in data acquisition. Therefore, it is necessary to propose a water level probe with an alarm function to provide a new technical solution to solve the technical problems mentioned in the above patent. Utility Model Content

[0005] Therefore, it is necessary to provide a water level probe with an alarm function to address the aforementioned technical problems. By setting up an automatic reading structure, when observing data, the distance to the measuring positioning plate is first measured using a laser rangefinder. This serves as the first observation data. By rotating the knob in conjunction with the shaft, the friction wheel is driven to rotate. As the friction wheel rotates, the measuring rod slides up and down inside the positioning sleeve until the bottom of the probe contacts the water surface. The distance to the measuring positioning plate is then observed using a laser rangefinder. The difference between the two distances is the change in water level. This effectively reduces the workload of operators and increases the accuracy of the measurement.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A water level measuring needle with an alarm function.

[0008] The water level probe with alarm function specifically includes a measuring rod, a positioning sleeve slidably connected to the surface of the measuring rod, a height adjustment structure inside the positioning sleeve, an automatic reading structure on the surface of the positioning sleeve, and a water level alarm structure at the bottom of the measuring rod.

[0009] A probe is fixedly connected to the bottom end of the measuring rod, a reading frame is provided on the surface of the positioning sleeve, and a positioning frame is fixedly connected to one side of the positioning sleeve.

[0010] As a preferred embodiment of the water level probe with alarm function provided by this utility model, the positioning sleeve has an clearance groove inside, and a shaft is rotatably arranged inside the clearance groove, with one end of the shaft extending to the outside of the positioning sleeve.

[0011] In a preferred embodiment of the water level probe with alarm function provided by this utility model, a friction wheel is fixedly connected to the surface of the shaft, the friction wheel is disposed inside the clearance groove, and the clearance groove is in close contact with the surface of the measuring rod. A knob is fixedly connected to one end of the shaft extending to the outside of the positioning sleeve.

[0012] As a preferred embodiment of the water level measuring needle with alarm function provided by this utility model, the automatic reading structure includes a laser rangefinder fixedly connected to the surface of the positioning sleeve, a top rod fixedly connected to the top of the measuring rod, a ranging positioning plate fixedly connected to the surface of the top rod, and the ranging positioning plate being vertically arranged with the laser rangefinder.

[0013] As a preferred embodiment of the water level probe with alarm function provided by this utility model, the water level alarm structure includes a positioning ring fixedly connected to the bottom end of the measuring rod, a control circuit board fixedly connected to the surface of the positioning ring, and two wires fixedly connected to the surface of the probe, the wires being electrically connected to the control circuit board.

[0014] In a preferred embodiment of the water level probe with alarm function provided by this utility model, the control circuit board includes a buzzer, a controller and an indicator light, and the wires are electrically connected to the controller.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The water level probe with alarm function provided by this utility model has an automatic reading structure. When observing data, it first measures the distance to the measuring positioning plate using a laser rangefinder, which serves as the first observation data. By rotating the knob in conjunction with the shaft, the friction wheel is driven to rotate. As the friction wheel rotates, the measuring rod slides up and down inside the positioning sleeve until the bottom of the probe contacts the water surface. The distance to the measuring positioning plate is then observed using the laser rangefinder. The difference between the two distances is the change in water level. This effectively reduces the workload of operators and increases the accuracy of measurement.

[0017] The water level probe with alarm function provided by this utility model has a water level alarm structure. When the water level reaches the two wires and comes into contact with the bare wires at the bottom of the wires, the resistance of the wires increases. The internal controller of the control circuit board monitors the water level and then controls the buzzer to sound an alarm. In this way, the real-time changes in water level can be monitored.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] As in the background technology, the water level probes currently used obtain water level change data by observing the difference between two water levels. Existing methods generally use mechanical positioning combined with human visual observation for data observation. The water level probes are usually installed at a low position, and the observers need to lower their posture to make observations. Even after lowering their posture, the observation is often done at an angle, which can lead to deviations in data acquisition.

[0028] To solve this technical problem, this utility model provides a water level probe with an alarm function.

[0029] For details, please refer to Figures 1-3 The water level probe with alarm function specifically includes a measuring rod 1, a positioning sleeve 2 slidably connected to the surface of the measuring rod 1, a height adjustment structure 6 inside the positioning sleeve 2, an automatic reading structure 7 on the surface of the positioning sleeve 2, and a water level alarm structure 8 at the bottom of the measuring rod 1.

[0030] A probe 5 is fixedly connected to the bottom end of the measuring rod 1, a reading frame 4 is provided on the surface of the positioning sleeve 2, and a positioning frame 3 is fixedly connected to one side of the positioning sleeve 2.

[0031] The water level probe with alarm function provided by this utility model, through the setting of automatic reading structure 7, first measures the distance to the measuring positioning plate 15 by laser rangefinder 13 when observing data. This is used as the first observation data. By rotating knob 12 in conjunction with shaft 10, the friction wheel 11 is driven to rotate. While the friction wheel 11 is rotating, the measuring rod 1 can slide up and down inside the positioning sleeve 2 until the bottom of the probe 5 contacts the water surface. The distance to the measuring positioning plate 15 is observed by laser rangefinder 13. The difference between the two is the change value of water level. This can effectively reduce the workload of operators and increase the accuracy of measurement.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] Example 1:

[0034] Please refer to Figures 1-4 A water level probe with an alarm function includes a measuring rod 1, a positioning sleeve 2 slidably connected to the surface of the measuring rod 1, a height adjustment structure 6 inside the positioning sleeve 2, an automatic reading structure 7 on the surface of the positioning sleeve 2, and a water level alarm structure 8 at the bottom end of the measuring rod 1.

[0035] A probe 5 is fixedly connected to the bottom end of the measuring rod 1, a reading frame 4 is provided on the surface of the positioning sleeve 2, and a positioning frame 3 is fixedly connected to one side of the positioning sleeve 2.

[0036] Specifically, the positioning sleeve 2 has an clearance groove 9 inside, and a shaft 10 is rotatably installed inside the clearance groove 9, with one end of the shaft 10 extending to the outside of the positioning sleeve 2.

[0037] Specifically, a friction wheel 11 is fixedly connected to the surface of the shaft 10. The friction wheel 11 is located inside the clearance groove 9, and the clearance groove 9 is in close contact with the surface of the measuring rod 1. A knob 12 is fixedly connected to one end of the shaft 10 that extends to the outside of the positioning sleeve 2.

[0038] Specifically, the automatic reading structure 7 includes a laser rangefinder 13 fixedly connected to the surface of the positioning sleeve 2, a top rod 14 fixedly connected to the top of the measuring rod 1, a ranging positioning plate 15 fixedly connected to the surface of the top rod 14, and the ranging positioning plate 15 is vertically arranged with the laser rangefinder 13.

[0039] With the above structural design, when using the device, first fix the positioning frame 3 to a certain place on the water surface. After that, turn the knob 12. When the knob 12 turns, it drives the shaft 10 to turn. When the shaft 10 turns, it rubs against the measuring rod 1. The measuring rod 1 slides up and down inside the positioning sleeve 2 through the friction of the friction wheel 11 until the lowest end of the probe 5 moves to be parallel to the water surface. At this time, turn on the laser rangefinder 13 to measure the distance to the ranging positioning plate 15 and record it. This can be used as the first observation data.

[0040] After a period of time, rotate knob 12 to move the bottom of probe 5 to be parallel to the water surface. After completion, control laser rangefinder 13 to observe the distance to the ranging positioning plate 15. This can be used as the second data. Observe the comparison between the first data and the second data, and the difference between the two is the water level change data.

[0041] Example 2:

[0042] The water level probe with alarm function provided in Example 1 has been further optimized, specifically, as follows: Figures 2-5 As shown, the water level alarm structure 8 includes a positioning ring 16 fixedly connected to the bottom end of the measuring rod 1. A control circuit board 17 is fixedly connected to the surface of the positioning ring 16. Two wires 18 are fixedly connected to the surface of the probe 5. The wires 18 are electrically connected to the control circuit board 17.

[0043] Specifically, the control circuit board 17 includes a buzzer, a controller, and an indicator light, and the wire 18 is electrically connected to the controller.

[0044] With the above structural design, when the water level alarm structure 8 is in use, the knob 12 is rotated. As the knob 12 rotates, the measuring rod 1 and the probe 5 are raised. Since the bottom end of the wire 18 is parallel to the bottom end of the probe 5, the bottom end of the probe 5 is moved to the preset height by rotating the knob 12. If the water level reaches the preset height, the resistance of the two wires 18 increases. After monitoring by the controller inside the control circuit board 17, the buzzer is controlled to sound an alarm.
