[0041] One embodiment of the present invention provides a wall-mounted water accumulation monitor, referring to Figures 1 to 8 ,include:

[0042] Power module 1;

[0043] A monitoring module 2 is electrically connected to the power module 1 and monitors the depth of accumulated water;

[0044] The inner shell 3 is provided with an installation cavity 31 for installing the power module 1 and the monitoring module 2;

[0045] The outer shell 4 is sleeved on the outside of the inner shell 3. The outer shell 4 is provided with a mounting hole 41. The mounting hole 41 is for screws to pass through and be embedded in the curb. The outer shell 4 is attached to the curb.

[0046] The wall-mounted water accumulation monitor of this embodiment is hung on a curb or a wall, so that the wall-mounted water accumulation monitor is located at the edge of the road and will not affect traffic. In addition, the wall-mounted water accumulation monitor fits the wall, avoiding damage to the road by drilling holes, reducing installation costs, and improving installation efficiency. The monitoring module 2 is fixed to the inner shell 3 and is used to monitor the water accumulation situation. The outer shell 4 is fixed on the outside of the inner shell 3. The outer shell 4 can protect the inner shell 3 monitoring module 2 and other items to prevent damage. A mounting hole 41 is provided on the side of the outer shell 4. One end of the screw is embedded in the curb or wall, and the other end is stuck on the inner side of the outer shell 4, so that the wall-mounted water accumulation monitor can be hung on the curb or wall, making it more beautiful and less prone to damage after installation than the traditional pole type and underground type. Specifically, the power supply module 1 is fixed in the mounting cavity 31 and is used to supply power to the monitoring module 2. The monitoring module 2 uses multiple monitoring methods to measure the real-time depth of water accumulation. A mounting hole 41 is opened on the side of the outer shell 4, and the screw is passed through the mounting hole 41. The radial width of the screw at one end on the inner side of the outer shell 4 is greater than the radial width of the mounting hole 41 to prevent the screw from detaching from the outer shell 4. It should be noted that the screws in this embodiment are not limited, and the screws can also be replaced by hooks set on the outer shell 4, and the hooks are hung on a pendant pre-set on the wall or curb.

[0047] Further, refer to Figure 4 and Figure 5 The housing 4 is provided with a fixing hole 42. The fixing hole 42 and the mounting hole 41 are respectively located on opposite sides of the housing 4 and aligned with each other. A mounting channel for the screw to pass through is formed between the fixing hole 42 and the mounting hole 41. The fixing hole 42 and the mounting hole 41 are respectively opened on opposite sides of the housing 4. The mounting hole 41 is located on one side of the housing 4 that is attached to the wall, and the fixing hole 42 is located on the other opposite side of the housing 4. At the same time, the fixing hole 42 and the mounting hole 41 are aligned with each other so that the axis of the fixing hole 42 and the axis of the mounting hole 41 are located on the same straight line. The mounting channel is for the screw to pass through. When installing a wall-mounted water accumulation monitor, the screw enters the mounting channel through the fixing hole 42 and passes through the mounting hole 41 along the mounting channel. The two ends of the screw are respectively located on both sides of the mounting hole 41, and one end of the screw is embedded in the curb or wall. The other end clamps the outer shell 4. In this embodiment, the installation channel is a non-enclosed channel between the fixing hole 42 and the mounting hole 41 for screws or installation tools to pass through. After the inner shell 3 is fixed inside the outer shell 4, the inner shell 3 is located outside the range of the installation channel, that is, the projection of the inner shell 3 on the plane where the mounting hole 41 is located is outside the projection range of the fixing hole 42 on the plane, so that the screw will not be blocked by the inner shell 3 when passing through the installation channel. It should be noted that, in other embodiments, the installation channel can also be a side enclosed channel connecting the fixing hole 42 and the mounting hole 41.

[0048] Furthermore, two mounting holes 41 are provided at intervals, one at each end of the housing 4 and at the same height. The two mounting holes 41 are located at either end of the housing 4, and two fixing holes 42 are provided, corresponding one-to-one with the mounting holes 41. The two mounting holes 41 are at the same height on the side of the housing 4, ensuring that the two screws remain at the same height after being inserted through the mounting holes 41, preventing one end of the wall-mounted water accumulation monitor from shifting. In this embodiment, the diameter of the fixing holes 42 is larger than that of the mounting holes 41. One mounting hole 41 extends vertically on the side of the housing 4, while the other extends horizontally on the side of the housing 4. This allows the screws to be adjusted within the mounting holes 41, maintaining the wall-mounted water accumulation monitor in a horizontal position.

[0049] Further, refer to Figures 2 to 8 The inner shell 3 includes a front shell 32 and a side plate 33 connected to each other, the installation cavity 31 is formed in the front shell 32, the side plate 33 covers and closes the opening of the installation cavity 31, and the outer shell 4 is fixed to the side plate 33. The power supply module 1 and the monitoring module 2 can be installed in the installation cavity 31 through the opening of the installation cavity 31. The side panels 33 close the installation cavity 31 to form a closed space in the installation cavity 31 to prevent accumulated water from entering the installation cavity 31. The side panels 33 are fixed to the front shell 32 by screws. It can be understood that the front shell 32 and the side panels 33 can also be fixed by waterproof adhesive. In this embodiment, when the front shell 32 and the side panels 33 are installed to the inside of the outer shell 4, the left and right ends of the side panels 33 abut against the left and right inner walls of the outer shell 4 to ensure that the front shell 32 and the side panels 33 will not shake relative to the outer shell 4. Avoidance notches 331 are respectively provided at both ends of the side panels 33 to avoid the installation channel. The length of the front shell 32 is smaller than the length of the side panels 33. There is a gap between the left and right side surfaces of the front shell 32 and the left and right inner walls of the outer shell 4 to avoid the installation channel.

[0050] Further, reference 3 to Figure 5 The side panels 33 have positioning grooves 332 formed on their surfaces, and an elastically bendable positioning piece 43 is provided on the side of the outer shell 4 proximal to the side panels 33. A mounting opening 44 for the inner shell 3 to enter is provided at the bottom of the outer shell 4. The positioning piece 43 snaps into the positioning groove 332, securing the outer shell 4 relative to the inner shell 3. In this embodiment, the side panels 33 facing away from the front shell 32 have positioning grooves 332, and the side of the outer shell 4 that abuts the side panels 33 is provided with positioning pieces 43. When the inner shell 3 enters the interior of the outer shell 4 through the mounting opening 44 at the bottom of the outer shell 4, the positioning piece 43 elastically bends and snaps into the positioning groove 332, thereby securing the outer shell 4 relative to the side panels 33.

[0051] Furthermore, the positioning piece 43 extends in the direction from the bottom to the top of the outer shell 4, and the extended end of the positioning piece 43 is in a suspended state. The positioning piece 43 is tilted toward the inside of the outer shell 4 during the extension process. In this embodiment, one end of the positioning piece 43 is connected to the side of the outer shell 4, and the positioning piece 43 extends in the direction from the bottom to the top of the outer shell 4. The extended part of the positioning piece 43 is in a suspended state. At the same time, the positioning piece 43 is tilted. In the extension direction from the bottom to the top of the outer shell 4, the positioning piece 43 is tilted toward the inside of the outer shell 4. When the inner shell 3 enters the inner shell 4 through the installation opening 44, the positioning piece 43 is squeezed by the side plate 33 and deformed in the direction away from the inside of the outer shell 4. The inner shell 3 is continuously pushed upward. The positioning piece 43 is located on the moving path of the positioning groove 332, so that the positioning piece 43 is stuck in the positioning groove 332. At the same time, the positioning piece 43 bends toward the inside of the outer shell 4 to restore the deformation. At this time, the inner shell 3 just fits with the top of the outer shell 4, the inner shell 3 and the outer shell 4 are positioned relative to each other, and the suspended end of the positioning piece 43 abuts the upper groove wall of the positioning groove 332 to prevent the inner shell 3 from falling off the outer shell 4 through the mounting opening 44. It should be noted that the extension direction of the suspended end of the positioning piece 43 in this embodiment can be adjusted according to the position of the mounting opening 44. In addition, in other embodiments, the positioning piece 43 may not be set to a form in which one end is suspended. For example, both ends of the positioning piece 43 are connected to the side surfaces of the outer shell 4, and the middle part of the positioning piece 43 bulges toward the interior of the outer shell 4. The bulge structure can be deformed under the pressure of the side plate 33 and elastically snapped into the positioning groove 332, thereby positioning the inner shell 3 relative to the outer shell 4.

[0052] Furthermore, two positioning grooves 332 are provided on the surface of the side panel 33 at intervals, and two positioning pieces 43 are provided corresponding to the positioning grooves 332 at intervals. The two positioning grooves 332 are provided at both ends of the side panel 33, and the number and position of the positioning pieces 43 correspond to the positioning grooves 332. When the inner shell 3 enters the inner shell 3 through the installation opening 44 and the top of the inner shell 3 is aligned with the top of the outer shell 4, the two positioning pieces 43 are simultaneously snapped into the two positioning grooves 332. It should be noted that the cooperation of the two positioning pieces 43 and the two positioning grooves 332 can make the snap-fit ​​and positioning between the inner shell 3 and the outer shell 4 more secure. It is understood that the number of positioning grooves 332 and positioning pieces 43 can also be three or four, etc.

[0053] Furthermore, the inner shell 3 also includes a waterproof ring 34 disposed between the front shell 32 and the side panels 33. The waterproof ring 34 is disposed around the opening edge of the mounting cavity 31. The shape of the waterproof ring 34 is consistent with the shape of the opening of the mounting cavity 31, so that the waterproof ring 34 can completely fit the opening edge of the mounting cavity 31. The waterproof ring 34 is a rubber ring. The side panels 33 cover the opening of the mounting cavity 31. The waterproof ring 34 seals the gap between the side panels 33 and the opening edge of the mounting cavity 31 to prevent moisture from entering the interior of the mounting cavity 31 through this gap. It should be noted that in other embodiments, the waterproof ring 34 can also be replaced by a sealant.

[0054] Furthermore, the housing 4 is made of metal. The metal material can be stainless steel, aluminum alloy, titanium alloy, nickel-based alloy, etc. The housing 4 can resist erosion by moisture and corrosive substances, protect the circuits and sensors inside the monitor, and extend the service life of the device. In addition, the housing 4 is made of metal to ensure that it has great hardness and strength to prevent accidental impact or knocks that may cause damage to the inner housing 3 and other devices.

[0055] Further, refer to Figures 6 to 8 The monitoring module 2 includes a main board 21, a contact electrode 22, a static pressure sensor 23 and an ultrasonic sensor 24. The contact electrode 22 is installed at the bottom of the shell, and the contact electrode 22 is used to detect the conductivity of rainwater. The static pressure sensor 23 is installed at the bottom of the shell, and the static pressure sensor 23 is used to detect the static pressure of accumulated water. The ultrasonic sensor 24 is installed at the top of the shell, and the ultrasonic sensor 24 is used to detect the height of the shell submerged by accumulated water.

[0056] In this embodiment, a plurality of contact electrodes 22 are provided and are respectively arranged on the bottom and side surfaces of the front shell 32. The contact electrodes 22 on the side surfaces of the front shell 32 are arranged at intervals along the height direction, and can be used for monitoring at different water levels. When the contact electrode 22 comes into contact with the accumulated water, the two contacts on the contact electrode 22 form a closed circuit, and current can flow between the contacts. At this time, the contact electrode 22 sends an electrical signal to the main board 21, and the main board 21 controls the static pressure sensor 23 to start. Conversely, when the contact electrode 22 detects that the accumulated water has subsided, it sends an electrical signal to the main board 21, and the main board 21 controls the static pressure sensor 23 to turn off. The static pressure sensor 23 is provided at the bottom of the front shell 32 and By detecting the static pressure of the accumulated water, the height of the accumulated water is calculated according to the ratio of pressure and density. When the static pressure sensor 23 detects that the height of the accumulated water submerges the front shell 32, the static pressure sensor 23 sends an electrical signal to the mainboard 21. The mainboard 21 controls the ultrasonic sensor 24 to start. The ultrasonic sensor 24 is fixed on the top of the front shell 32. The ultrasonic sensor 24 is provided with an ultrasonic transmitting device and an ultrasonic receiving device. The height of the accumulated water submerging the front shell 32 is detected by calculating the time difference between the emission and reception of the ultrasonic wave. Specifically, in this embodiment, the wall-mounted water accumulation monitor is miniaturized as a whole. The length of the device is 166 mm, the width is 84.5 mm, and the thickness is 49.5 mm.

[0057] The wall-mounted water accumulation monitor also includes a communication system 5, which transmits the detection data of the monitoring module 2 to the monitoring platform in real time; the communication system 5 includes a mobile communication module 51 and a LoRa communication module 52, and the mobile communication module 51 and the LoRa communication module 52 are simultaneously arranged on the mainboard 21, and the two do not interfere with each other. The installer can choose to activate according to the signal conditions of the installation point without having to re-disassemble the communication module. The communication system 5 also includes an antenna 53, which is used to receive and send wireless signals so that the wall-mounted water accumulation monitor can communicate with the remote monitoring platform. The mobile communication module 51 generally includes but is not limited to 4G and 5G networks. It should be noted that in this embodiment, since the outer shell 4 is made of metal, the outer shell 4 is mounted on the outside of the inner shell 3, which will provide certain signal shielding for the antenna 53. The outer shell 4 is provided with a signal avoidance opening 45 at a position opposite to the antenna 53.

[0058] The power module 1 includes a battery 11, a wired charging assembly 12, and a wireless charging assembly 13, both of which are electrically connected to the battery 11. The battery 11 can be a rechargeable lithium battery 11. The combination of the wired charging assembly 12 and the wireless charging assembly 13 provides the wall-mounted water accumulation monitor with multiple charging options, improving battery life and making charging more convenient.
