Description

Technical Field

[0001] This application belongs to the field of water level measurement technology, and specifically relates to a radar water level monitoring device. Background Technology

[0002] A level gauge is an instrument used to detect the position and boundary of a liquid. It measures and records the horizontal height of the liquid in a container through different working principles. There are many types of level gauges, the most common being magnetic float level gauges, magnetostrictive level gauges, radar level gauges, and ultrasonic level gauges.

[0003] Currently, radar sensors in radar level gauges are directly exposed to the measurement environment. This means the radar sensor is fixedly mounted above the measurement area using a bracket, as seen in utility model patents CN 220366222U (a self-recording radar level detector) and CN221223919U (a signal station radar level gauge). This external structure is ill-suited to the complex environment of paddy field water level monitoring. Dense rice paddies and abundant foliage can obstruct the radar sensor's measurement path, affecting radio wave transmission and reception, thus reducing the accuracy of water level measurements.

[0008] In some embodiments, the main housing is provided with a locking groove, and the filter plate is provided with vertically adjacent locking parts and clearance grooves. The filter plate can move vertically relative to the main housing to switch between a locked position and an unlocked position. In the locked position, the locking part is aligned and locked within the locking groove; in the unlocked position, the clearance groove is aligned with the locking groove, allowing the filter plate to be separated from the main housing.

[0011] In some embodiments, the power supply module further includes a solar panel fixed to the top of the waterproof housing, and the battery is electrically connected to the solar panel.

[0012] In some embodiments, the waterproof housing includes a main housing, a top housing, and a bottom housing, and waterproof gaskets are provided at the connection between the top housing and the main housing, as well as at the connection between the bottom housing and the main housing.

Detailed Implementation

[0019] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0020] This invention proposes a radar water level monitoring device for measuring the water level in paddy fields.

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figures 1 to 6 As shown, in a specific embodiment of this utility model, the radar water level monitoring device 100 includes a housing 10, a radar sensor 20, and a filter assembly 30. The housing 10 includes an inner cavity 10a and a water inlet that penetrates the outer wall of the housing 10. The radar sensor 20 is built into the inner cavity 10a and is used to measure the water level in the inner cavity 10a. The filter assembly 30 is detachably disposed in the housing 10 and is used to filter the liquid entering the inner cavity 10a from the water inlet.

[0023] The interior of the housing 10 is hollow, forming an inner cavity 10a to contain the liquid to be tested. An inlet is provided through the side wall of the housing 10 near the bottom to ensure that water from the paddy field can enter the inner cavity 10a through this inlet, and to maintain the water level in the inner cavity 10a consistent with the water level in the paddy field. The housing 10 can be a single main housing 11, or it can be formed by connecting an upper pipe 12 and a lower main housing 11. The pipe 12 and the main housing 11 are fixed together by welding, threaded connection, or snap-fit ​​connection. A reinforcing plate is provided at the connection between the pipe 12 and the main housing 11. The cavity of the pipe 12 and the inner cavity of the main housing 11 together form the inner cavity 10a. The tube 12 has a slender tube structure, and its cross-section can be circular or square. The purpose of adding the tube 12 is to increase the measuring range. That is, when the main box 11 alone cannot meet the high water level of the paddy field, the tube 12 extending upward from the top of the main box 11 can increase the measurable range in vertical height, thereby adapting to the measurement of different water levels. When the main box 11 is used alone, the radar sensor 20 is built into the top of the main box 11. When the tube 12 and the main box 11 are used, the radar sensor 20 is built into the top of the tube 12. A connector 13 is provided at the top of the tube 12 for fixing the radar sensor 20.

[0024] like Figure 4 and Figure 6 As shown, the radar sensor 20 includes an upper housing 21, a lower housing 22, a sensor, a radar data interface 23, and a level calibrator. The upper housing 21 is detachably connected to the connector 13 via threaded fasteners, and the upper housing 21 and the lower housing 22 are also connected via threaded fasteners. The sensor is installed within the cavity formed by the upper housing 21 and the lower housing 22, with the sensor's detection end facing the inner cavity 10a of the housing and used for water level measurement. The radar data interface 23 is installed on the outside of the lower housing 22 via a waterproof connector, which can be an aviation connector. The radar data interface 23 is electrically connected to the internal sensor and transmits data to an external system. The level calibrator is located in the middle of the upper housing 21 and is used to determine whether the installation position of the radar sensor 20 meets the level requirements.

[0025] The function of the filter assembly 30 is to filter the liquid entering the inner cavity 10a of the tank. Understandably, the water in the paddy field is prone to carrying branches, leaves, weeds, mud, sand or other floating objects. When the water carrying impurities enters the inner cavity 10a of the tank, it will also affect the measurement results of the radar sensor 20. When a large amount of debris accumulates in the inner cavity 10a of the tank, it will also cause the radar sensor 20 to malfunction. Therefore, it is quite necessary to set the filter assembly 30 at the water inlet. The filter assembly 30 is fixed at the water inlet of the tank 10 in a detachable connection manner, that is, the water in the paddy field must pass through the filter assembly 30 before entering the inner cavity 10a of the tank.

[0026] The working principle of this invention is as follows: The radar water level monitoring device 100 is placed in the paddy field water area to be monitored. External water enters the inner cavity 10a of the tank through the inlet. The incoming water first passes through the filter assembly 30, thus effectively intercepting impurities. The liquid entering the inner cavity 10a is relatively clean, providing a better measurement environment for the radar sensor 20. The radar sensor 20 transmits radio waves to the water surface in the inner cavity 10a and receives the returned radio waves to calculate the water level. Because the radar sensor 20 is built-in and the water entering the inner cavity 10a is filtered, the measurement results are not affected by the external environment, thereby improving measurement accuracy.

[0027] like Figure 6 and Figure 7 As shown, in an embodiment of this utility model, the filter assembly 30 includes a filter plate 31 and a sedimentation tank 32. The filter plate 31 is used to cover the water inlet and has multiple filter holes 311. The sedimentation tank 32 is used for sediment deposition and is located at the bottom of the main tank 11.

[0028] The filter plate 31 and the sedimentation tank 32 can be either an integrated structure or a separate structure. When using an integrated structure, the bottom end of the filter plate 31 is fixedly connected to the top of the sedimentation tank 32, which can be achieved through welding, snap-fit ​​connection, or fasteners. The filter plate 31 and sedimentation tank 32 are installed or disassembled as a single unit. When using a separate structure, installation or disassembly is performed sequentially. During installation, the sedimentation tank 32 is first placed at the bottom of the main housing 11, followed by the installation of the filter plate 31. The bottom end of the filter plate 31 abuts against the top of the sedimentation tank 32, providing a limiting and pressing effect. During disassembly, the filter plate 31 is first separated from the main housing 11 to release the constraint on the sedimentation tank 32, and then the sedimentation tank 32 is removed from the bottom of the main housing 11. Because the filter assembly 30 is in long-term contact with water, both the filter plate 31 and the sedimentation tank 32 are made of corrosion-resistant materials.

[0029] like Figure 6 and Figure 7 As shown, the filter plate 31 has a flat structure, and its shape is adapted to the shape of the water inlet on the main box 11. The filter plate 31 covers the water inlet from the outside of the main box 11. The filter plate 31 has a number of evenly distributed filter holes 311. The filter holes 311 are used to filter impurities in the paddy field water, such as branches, leaves, weeds or other floating objects. The shape of the filter holes 311 can be round or strip-shaped. The size of the opening can filter impurities without affecting the flow of water.

[0030] like Figure 6 and Figure 7 As shown, the sedimentation tank 32 is a structure of the tank body 10, placed at the bottom of the main tank body 11 to collect settled sediment. The sedimentation tank 32 is a one-piece molded structure. The horizontal projection of the sedimentation tank 32 matches the cross-section of the main tank body 11, meaning that all sediment settling from the main tank body 11 can fall into the sedimentation tank 32, preventing sediment from accumulating in the gap between the main tank body 11 and the sedimentation tank 32 and becoming difficult to clean. The top of the sedimentation tank 32 has multiple circular holes arranged in a matrix. When the water entering the inner cavity 10a of the tank body is mixed with sediment, the sediment settles downwards due to gravity and enters the sedimentation tank 32 through the multiple circular holes for temporary collection. The bottom of the sedimentation tank 32 is sloped, which guides and collects the sediment. The front side of the sedimentation tank 32 has a hook near the top, which is hung on the main tank body 11 for positioning. The rear side of the sedimentation tank 32 forms an opening, through which sediment can be poured out after the sedimentation tank 32 is removed. The sedimentation tank 32 can serve as a temporary collection point for sediment. Maintenance personnel only need to clean the sedimentation tank 32 during the planting season, which greatly reduces maintenance costs.

[0031] like Figure 5 , Figure 6 and Figure 7As shown in the embodiment of this utility model, the main housing 11 is provided with a locking groove 111, and the filter plate 31 is provided with a vertically adjacent locking part 312 and a clearance groove 313. The filter plate 31 can move vertically relative to the main housing 11 to switch between a locked position and an unlocked position. In the locked position, the locking part 312 is aligned and locked in the locking groove 111. In the unlocked position, the clearance groove 313 is aligned with the locking groove 111, so that the filter plate 31 can be separated from the main housing 11.

[0032] This detachable structure is applicable to both integrated and split-type filter assemblies 30. When using an integrated structure, the filter plate 31 and the sedimentation box 32 are treated as a whole. That is, when the filter plate 31 moves vertically relative to the main housing 11, the sedimentation box 32 moves synchronously to achieve installation or disassembly. When using a split structure, when the filter plate 31 moves vertically relative to the main housing 11 until the clearance groove 313 aligns with the locking groove 111, the filter plate 31 is first separated from the main housing 11, and then the sedimentation box 32 is removed from the bottom of the main housing 11.

[0033] Taking the integrated filter assembly 30 as an example, during installation, first align the clearance groove 313 of the filter plate 31 with the locking groove 111. At this time, the sedimentation box 32 is located inside the main housing 11. Then, move the filter assembly 30 downwards until the locking part 312 of the filter plate 31 is aligned and locked in the locking groove 111. At this time, the sedimentation box 32 also moves downwards to the bottom of the main housing 11. The installation process is simply switching from the unlocked position to the locked position. During disassembly, first move the filter assembly 30 upwards until the clearance groove 313 of the filter plate 31 is aligned with the locking groove 111. At this time, the filter plate 31 can be separated from the main housing 11. When the filter plate 31 is separated, the sedimentation box 32 also separates from the bottom of the main housing 11 simultaneously, achieving overall disassembly. The disassembly process is simply switching from the locked position to the unlocked position.

[0034] like Figure 6 and Figure 7 As shown, in order to facilitate the disassembly of the filter plate 31, the filter plate 31 is also provided with a handle 314, which is located at the top of the filter plate 31.

[0035] like Figure 6 and Figure 7 As shown, the opposite sides of the filter plate 31 are bent to form guide portions, which cooperate with the main housing 11 to improve the accuracy of the vertical movement of the filter plate 31.

[0036] like Figure 1 , Figure 2 and Figure 4As shown in the embodiment of this utility model, the radar water level monitoring device 100 further includes a control gateway 40. The control gateway 40 includes a power supply module 41, a communication and data processing module 42, and a waterproof housing 43. The power supply module 41 includes a battery 411 electrically connected to the radar sensor 20; the communication and data processing module 42 is electrically connected to the radar sensor 20; the waterproof housing 43 is connected to the housing 10, and the battery 411 and the communication and data processing module 42 are installed inside the waterproof housing 43. Specifically, the radar data interface 23 of the radar sensor 20 is electrically connected to the communication and data processing module 42, and the bottom of the waterproof housing 43 is fixed to the connector 13 by fasteners.

[0037] like Figure 4 and Figure 5 As shown, specifically, the power supply module 41 also includes a solar panel 412 fixed to the top of the waterproof housing 43, and the battery 411 is electrically connected to the solar panel 412. The top of the waterproof housing 43 is provided with a groove for placing the solar panel 412. The solar panel 412 is fixed in the groove with waterproof adhesive. The top end face of the solar panel 412 is flush with the top of the waterproof housing 43. The waterproof housing 43 has a wire hole, through which the wires of the solar panel 412 pass into the waterproof housing 43 and are electrically connected to the battery 411.

[0038] like Figure 1 and Figure 4 As shown, the waterproof outer casing 43 includes a main casing 431, a top casing 432, and a bottom casing 433. Waterproof rubber rings are provided at the connections between the top casing 432 and the main casing 431, and between the bottom casing 433 and the main casing 431. The main casing 431 and the top casing 432, as well as the main casing 431 and the bottom casing 433, are detachably connected via threaded fasteners. The communication module 42 uses 4G communication and is mounted inside the top casing 432 via fasteners. The battery 411 is placed inside the main casing 431.

[0039] like Figure 1 and Figure 4 As shown, the control gateway 40 also includes an external output module 44 for connecting to external devices. The external output module 44 is electrically connected to the communication and data processing module 42. The external output module 44 is installed on the outer wall of the main housing 431 and collects the data acquired by the communication and data processing module 42 and outputs it to external devices.

[0040] like Figure 1 and Figure 4 As shown, the control gateway 40 also includes: Emergency charging module 45 for emergency charging; And / or, a power display module 46 for displaying the remaining power; And / or, a switching module 47 for controlling the on / off state of the circuit.

[0041] The emergency charging module 45 is installed on the outer wall of the main housing 431. In one embodiment, the connector of the external output module 44 and the connector of the emergency charging module 45 are both installed at the bottom of the main housing 431 and are located on the left and right sides of the main housing 431, respectively.

[0042] The power display module 46 is installed on the front of the main housing 431. Placing the power display module 46 in a prominent position on the control gateway 40 allows for easy observation and monitoring of the remaining power of the battery 411 at any time.

[0043] The switch module 47 is also mounted on the front of the main housing 431 for easy operation and control of the product's circuit switching.

[0044] This utility model features an integrated control gateway 40 on the top of the housing 10. By optimizing the spatial layout, it enhances the integration of the product, thereby reducing the overall size of the product and increasing its applicability.
