Description

Technical Field

[0001] This utility model relates to the field of wireless radar sensor technology, specifically a wireless radar sensor for water accumulation in urban utility tunnels. Background Technology

[0002] Urban integrated utility tunnels refer to underground tunnel spaces in cities that integrate various engineering pipelines such as electricity, communication, heating, and water supply. Above-ground structures include outlets and ventilation openings. They are crucial infrastructure and "lifelines" for ensuring urban operation. To guarantee the safety of urban integrated utility tunnel operations, water accumulation monitoring equipment such as wireless radar sensors is typically installed inside. Wireless radar sensors are high-performance liquid level / distance monitoring devices that integrate liquid level / distance acquisition and wireless data communication. They utilize low-power battery power (4G, NB-IoT) and other wireless communication protocols, with an STM32M4 core chip as the main control MCU. This high-precision ranging module can achieve ranging capabilities within a range of 0.05 to 40.0 meters, with millimeter-level accuracy. This series of wireless radar sensors features a built-in MCU and a low-power design, enabling wireless transmission of on-site water level and distance data to the cloud. They are widely used in water accumulation and flood control monitoring. Existing wireless radar sensors are listed in the instruction manual. Figure 4 and 5 .

[0003] Existing wireless radar sensors for urban utility tunnel water accumulation are typically mounted directly to the side wall of the tunnel using fixed brackets. However, they often encounter the following problems during use: 1. Some urban utility tunnels have sloping side walls. When the installation location is tilted, the wireless radar sensor itself may tilt, affecting its normal vertical downward monitoring. There is a lack of a flexible adjustment mechanism for the wireless radar sensor when installed in a tilted position, requiring manual adjustment with the help of shims or other materials, resulting in unsatisfactory flexibility. 2. The wireless radar sensor cannot be automatically cleaned of dust during monitoring. Over time, dust easily accumulates on the outside of the sensor, interfering with monitoring and reducing its stability. Therefore, this application proposes a wireless radar sensor for urban utility tunnel water accumulation to solve the above-mentioned problems. Utility Model Content

[0023] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 5 As shown in the figure, the wireless radar sensor for urban utility tunnel water accumulation proposed in this embodiment includes a wireless radar sensor body 1. An external threaded sleeve 101 is fixedly connected to the top of the wireless radar sensor body 1. An internal threaded sleeve 2 is threaded on the external threaded sleeve 101. A support rod 201 is fixedly connected to the right side of the internal threaded sleeve 2. An inclined adjustment component is fixedly connected to the right end of the support rod 201. The inclined adjustment component is used to flexibly adjust the wireless radar sensor body 1 in multiple directions when the installation position of the urban utility tunnel is tilted, so that it can perform stable vertical downward water accumulation monitoring without being affected by the on-site installation position.

[0025] An unobstructed rotating dust removal mechanism is installed on the outer side of the internal threaded sleeve 2. This mechanism includes a support sleeve 4 fixedly fitted at the bottom of the outer side of the internal threaded sleeve 2. The external threaded sleeve 101 and the wireless radar sensor body 1 are both located within the support sleeve 4. An external gear ring 405 is rotatably and sealingly fitted on the outer side of the support sleeve 4. Two sealed bearings 409 are fixedly fitted inside the external gear ring 405. The inner rings of the sealed bearings 409 are fixedly fitted to the outer side of the support sleeve 4, achieving a sealed rotatable installation of the external gear ring 405. A timer controller 408 and an electrically connected rotary drive assembly and air supply assembly are fixedly installed on the top of the support rod 201. The rotary drive assembly and the external... The right side of the gear ring 405 meshes and is used to drive the outer gear ring 405 to rotate. The right end of the air supply component extends into the outer gear ring 405 and is used to supply air into it. The right side of the outer gear ring 405 is fitted with a cleaning component that communicates with its interior. The cleaning component is located on the right side of the wireless radar sensor body 1 and is used to clean the dust from its sides and bottom. The rotary drive component is used to drive the outer gear ring 405 to rotate at regular intervals under the control of the timer controller 408. The air supply component is used to supply air into the outer gear ring 405 at regular intervals under the control of the timer controller 408. The cleaning component is used to clean the dust around the outside of the wireless radar sensor body 1 when the outer gear ring 405 rotates and air is supplied.

[0026] Specifically, the tilting adjustment assembly includes a fixed base 3. The right side of the fixed base 3 has four rectangular mounting holes. A ball sleeve 301 with an open left side is fixedly connected to the left side of the fixed base 3. A universal ball 303 is fitted inside the ball sleeve 301. The outer side of the universal ball 303 is covered with an anti-slip rubber sheet that makes contact with the inner wall of the ball sleeve 301. A knob-type bolt 302 makes contact with the bottom of the anti-slip rubber sheet. A threaded hole for threaded connection with the knob-type bolt 302 is located at the bottom of the ball sleeve 301. The left side of the universal ball 303 extends outside the ball sleeve 301 and is fixedly connected to the right end of the support rod 201. The fixed base 3, ball sleeve 301, universal ball 303, anti-slip rubber sheet, knob-type bolt 302, and threaded hole work together to fix the fixed base 3 to the wall of the urban utility tunnel or other carrier using external bolts. This is particularly useful when the installation location is on an inclined surface. When the entire structure is tilted, the wireless radar sensor body 1 needs to be adjusted to be vertically downward. During adjustment, rotate the knob bolt 302 in the opposite direction to move it downward and release the lock on the universal ball 303. At this time, the support rod 201 can be rotated up, down, forward, or backward to make the internal threaded sleeve 2 tilt and rotate. The internal threaded sleeve 2 drives the wireless radar sensor body 1 to rotate through the external threaded sleeve 101. When the wireless radar sensor body 1 is rotated and adjusted to be vertically downward, rotate the knob bolt 302 in the forward direction to press it upward against the anti-slip rubber, thereby locking the universal ball 303. By utilizing the multi-directional rotation adjustment of the universal ball 303, flexible multi-directional adjustment can be made to the wireless radar sensor body 1 when the installation position of the urban utility tunnel is tilted, so that it can perform stable vertical downward water accumulation monitoring work regardless of the on-site installation position, thus improving the flexibility of use.

[0027] Furthermore, the rotary drive assembly includes a motor 402 fixedly mounted on the top of the support rod 201 and electrically connected to the timer controller 408. The output shaft of the motor 402 extends to the bottom of the support rod 201 and is fixedly connected to a gear 401 that meshes with the right side of the external gear ring 405. The motor 402 and gear 401 are configured to cooperate, and the timer controller 408 is used to pre-set the start and stop times of the motor 402 according to the on-site cleaning requirements. When the cleaning time is reached, the timer controller 408 controls the motor 402 to start, causing it to drive the gear 401 to rotate. The gear 401 drives the external gear ring 405 that meshes with it to rotate. When the stop time is reached, the timer controller 408 controls the motor 402 to stop.

[0028] Furthermore, the air supply assembly includes a small air pump 403 fixedly installed on the top left side of the support rod 201 and electrically connected to the timer controller 408. The air outlet of the small air pump 403 extends into the support sleeve 4 and is connected to an L-shaped tube 404. The right end of the L-shaped tube 404 is located between two sealed bearings 409 and extends into the outer gear ring 405. A through hole is provided on the inner right side wall of the support sleeve 4 for fixed connection with the outer side of the L-shaped tube 404. The two sealed bearings are provided. 409 also serves to block and restrict the gas above and below the right end of the L-shaped tube 404; the small air pump 403 and the L-shaped tube 404 are designed to work together, and the start and stop times of the small air pump 403 are preset by the timer controller 408 according to the on-site cleaning requirements. When the cleaning time is reached, the timer controller 408 controls the small air pump 403 to start and supply air to the outer gear ring 405 through the L-shaped tube 404. When the stop time is reached, the timer controller 408 controls the small air pump 403 to stop.

[0029] Furthermore, the cleaning assembly includes a cleaning tube 406 embedded and fixed to the right side of the outer gear ring 405 and connected to its interior. The bottom end of the cleaning tube 406 is laterally aligned with the bottom of the wireless radar sensor body 1. Multiple air-blowing heads 407, tilted downwards and to the left, are fixed to the left side of the cleaning tube 406 and are located on the right side of the wireless radar sensor body 1. The cleaning tube 406 and air-blowing heads 407 work together, causing the cleaning tube 406 to rotate around the wireless radar sensor body 1 when the outer gear ring 405 rotates, thus driving multiple air-blowing heads to rotate. The head 407 rotates around the wireless radar sensor body 1. After the gas is supplied into the outer gear ring 405, it enters the cleaning pipe 406. Part of the gas is blown out through the bottom end of the cleaning pipe 406 to clean the bottom of the wireless radar sensor body 1, and another part of the gas is blown out through multiple air blowing heads 407 to clean the outside of the wireless radar sensor body 1. With the rotation, the bottom and outside of the wireless radar sensor body 1 are cleaned by blowing around it, which reduces the amount of dust and impurities covering the outside and affects the normal monitoring operation of the wireless radar sensor body 1, and improves the stability of use.

[0030] The usage method of this embodiment is as follows: When in use, the fixing base 3 is installed and fixed on the urban utility tunnel wall or other carriers by external bolts. When the whole body is tilted due to factors such as the installation position being on an inclined surface, the wireless radar sensor body 1 needs to be adjusted to be vertically downward. During adjustment, the knob bolt 302 is rotated in the opposite direction to make it move downward and release the lock on the universal ball 303. At this time, the support rod 201 can be rotated up, down, forward or backward to make it drive the inner threaded sleeve 2 to tilt and rotate. The inner threaded sleeve 2 drives the wireless radar sensor body 1 to rotate through the outer threaded sleeve 101. When the wireless radar sensor body 1 is rotated and adjusted to be vertically downward, the knob bolt 302 is rotated in the forward direction to make it press against the anti-slip rubber, thereby locking the universal ball 303. By using the multi-directional rotation adjustment of the universal ball 303, the wireless radar sensor body 1 can be flexibly adjusted in multiple directions when the installation position of the urban utility tunnel is tilted, so that it can perform stable vertical downward water accumulation monitoring work without being affected by the on-site installation position, improving the flexibility of use and making it convenient for installation work on various inclined surfaces.

[0031] The start and stop times of the control motor 402 and the small air pump 403 are preset using the timer controller 408 according to the on-site cleaning requirements. When the cleaning time is reached, the timer controller 408 controls the motor 402 and the small air pump 403 to start. The motor 402 drives the gear 401 to rotate, and the gear 401 drives the outer gear ring 405 meshing with it to rotate. When the outer gear ring 405 rotates, it drives the cleaning pipe 406 to rotate around the wireless radar sensor body 1. The cleaning pipe 406 drives multiple air blowing heads 407 to rotate around the wireless radar sensor body 1. When the small air pump 403 starts, it supplies air into the outer gear ring 405 through the L-shaped pipe 404. After the air is supplied into the outer gear ring 405, it enters the cleaning pipe 406. A part of the air is blown out through the bottom end of the cleaning pipe 406 to blow air onto the bottom of the wireless radar sensor body 1. In addition to dust removal, another portion of the gas is blown out through multiple air nozzles 407 to remove dust from the outside of the wireless radar sensor body 1. Combined with the rotation of the cleaning pipe 406 and the air nozzles 407, this achieves a complete surrounding dust removal operation on the bottom and outside of the wireless radar sensor body 1. When the closing time is reached, the timer controller 408 controls the motor 402 and the small air pump 403 to shut down, waiting for the next cleaning time to restart the rotating surrounding dust removal operation. This achieves the effect of automatically and periodically cleaning the bottom and outside of the wireless radar sensor body 1, reducing the phenomenon of large amounts of dust and impurities adhering and covering the outside, affecting the normal monitoring operation of the wireless radar sensor body 1. Furthermore, the air-blowing dust removal method does not interfere with the wireless radar sensor body 1, improving operational stability.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
