Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rainfall detection, and further relates to a rainfall detection device and an outdoor equipment. BACKGROUND

[0002] At present, the rainfall detection device commonly used by outdoor equipment is usually composed of a water storage platform and two exposed electrodes. The electrodes determine whether precipitation occurs according to the change of the liquid level. When rainwater accumulates to a certain liquid level, conduction will occur between the electrodes, reflecting the existence of rainfall, and prompting whether the equipment needs to be shut down. However, such a device has a significant defect: when the external precipitation is small and lasts for a long time, the water storage platform may continuously accumulate water, causing the liquid level to rise and triggering the conduction of the electrodes. However, this does not necessarily mean that the actual precipitation has reached a sufficient degree to affect the normal operation of the equipment. Since the specific amount or intensity of precipitation cannot be accurately measured, the existing device is prone to false judgments, causing the equipment to fail to respond to the actual changes in the working environment in a timely manner, thereby reducing the practicality and accuracy of the device.

[0015] In some embodiments, the electrode assembly includes at least three electrodes;

[0016] In the electrodes, at least two of the electrodes have different heights, which are used to adapt to different liquid level heights in the water storage space, so that when the liquid level height in the water storage space changes, different resistance values are sampled through the conduction state of the electrodes of different heights to prompt the change of rainfall.

[0017] In some embodiments, the electrode assembly includes a first electrode, a second electrode, and a high electrode, the first electrode is the lowest in height among the electrodes, the height of the second electrode is greater than or equal to the height of the first electrode, and when the first electrode and the second electrode are conductive, the working condition is the first state.

[0018] The height of the high electrode is greater than the height of the second electrode, and the outer periphery of the high electrode is provided with an insulating material, the height of the insulating material is at least equal to the height of the second electrode, which is used to prevent misjudgment caused by the conduction of the high electrode in the first state.

[0019] In some embodiments, the electrode assembly includes four electrodes, the high electrode includes a first high electrode and a second high electrode, the height of the first high electrode is greater than the height of the second high electrode, and the height of the second high electrode is greater than the height of the second electrode.

[0020] In the use state, when the accumulated water in the water storage space conducts the first electrode and the first high electrode, a first specific resistance value is formed, which is used to determine that the outdoor equipment is in a heavy rain environment; when the accumulated water in the water storage space conducts the first electrode and the second high electrode, a second specific resistance value is formed, which is used to determine that the outdoor equipment is in a moderate rain or moderate heavy rain environment.

[0037] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0038] The rain detection device commonly used by existing outdoor equipment (such as communication base stations, power facilities, etc.) is generally composed of a water storage container and a pair of exposed detection electrodes. Its working principle is: when it rains, the water storage container collects the precipitation, and when the liquid level rises to a preset height, the electrodes are turned on, triggering the equipment shutdown protection. However, this traditional structure has significant defects, for example, in the case of persistent light precipitation (such as light rain for a long time), although the precipitation per unit time is low, the accumulated liquid level will still reach the trigger threshold, which cannot correctly judge the rainfall, and is easy to cause the outdoor equipment to produce false shutdown action, seriously affecting the rationality and efficiency of the equipment operation.

[0039] To solve the above problems, referring to the drawings attached to the specification Figure 1 A rain detection device is provided, which can avoid false judgment caused by existing devices due to accumulated water, and improve the rainfall detection accuracy and reliability of outdoor equipment.

[0040] In one embodiment, referring to the drawings attached to the specification Figure 1 A rain detection device is provided, which is widely used in various outdoor equipment, especially in complex weather conditions, for accurate detection of precipitation and determination of whether the equipment should stop working. The basic structure of the rain detection device includes a main body 1, an electrode assembly 2 and a control end.

[0041] First, the main body 1 is the core part of the rain detection device, as shown in the figure, the main body 1 is provided with an open water storage space 100, which is mainly used for collecting and containing rainwater. The size and volume of the water storage space 100 can be designed in different specifications according to actual needs to adapt to the precipitation measurement in different scenes.

[0042] The side wall of the main body 1 is provided with a drainage groove 10, which is arranged along the height direction of the water storage space 100 and is in communication with the water storage space 100. Its main function is to timely remove the excess accumulated water in the water storage space 100, prevent too much rainwater from accumulating, and affect the correctness of the rainfall detection. It can be understood that in the case of small precipitation, the drainage groove 10 can effectively drain excess accumulated water, maintain the stability of the liquid level, prevent the accumulated water from misdirecting the electrodes, and cause false judgment; of course, in the case of heavy rainfall, the design of the drainage groove 10 can effectively prevent the liquid level from being too high, and ensure the normal working state of the electrode assembly 2.

[0043] The electrode assembly 2 is arranged in the water storage space 100, and generally includes at least two electrodes, which can be flexibly designed in different embodiments in terms of arrangement position and electrical connection mode. The electrode assembly 2 serves to judge the change of precipitation amount through the change of liquid level. When the accumulated water in the water storage space 100 reaches a certain height, the conduction state between the electrodes will change, thereby changing the resistance value in the circuit. The control end can judge the state of the working condition by receiving the resistance value signal when the electrodes are turned on, and further judge the precipitation intensity.

[0044] In the embodiment, the function of the control end is to judge the working condition "first state" or "second state" according to the resistance value change when the electrodes are turned on. Specifically, the first state refers to the drainage speed of the accumulated water in the water storage space 100 being greater than the water storage speed, which indicates that the precipitation amount is small, for example, light rain, and the device can still operate normally. The second state refers to the drainage speed of the accumulated water in the water storage space 100 being less than or equal to the water storage speed, which generally indicates that the precipitation amount is large, for example, heavy rain, and the device should be selected to stop working according to actual needs.

[0045] It can be understood that the embodiment solves the problem of electrode misjudgment caused by the failure of rainwater to be discharged in time in the prior art by arranging the drainage groove 10. The design of the drainage groove 10 not only ensures that the accumulated water can be discharged in time in light rain to avoid affecting the judgment of the electrodes, but also effectively reduces the situation of high liquid level in heavy rain to avoid misjudgment caused by excessive accumulated water. Therefore, the device has high practicability and stability, and is especially suitable for the automatic management of various outdoor devices in different weather environments.

[0046] It should be noted that, first, the number and layout of the electrodes can be adjusted according to different application scenarios. For example, multiple electrodes can be arranged for liquid level detection at different heights to further improve the detection accuracy; or different electrode configurations can be designed according to the size of the water storage space 100 to adapt to outdoor devices of different specifications.

[0047] In addition, the control end can be connected with an external intelligent system to monitor the rainfall data in real time and automatically adjust the working state of the device according to the precipitation intensity. For some scenes that require more intelligentization, wireless communication technology can be used to transmit data to a remote monitoring platform to provide remote management and maintenance functions.

[0048] Based on the above embodiment, in one embodiment, the drainage groove 10 extends from the top to the bottom of the main body part 1, forming a drainage channel through the wall thickness of the main body part 1, thereby enhancing the drainage effect and improving the drainage efficiency. The bottom of the drainage groove 10 is flush with the bottom of the water storage space 100, so that the accumulated water in the water storage space 100 can be completely discharged through the drainage groove 10.

[0049] Specifically, the design of the drain groove 10 enables the accumulated water in the water storage space 100 to flow smoothly to the drain groove 10, avoiding the problem of water stagnation in the water storage space 100. Since the bottom of the drain groove 10 is flush with the bottom of the water storage space 100, it ensures that the water flow can pass through the drain channel unobstructed, effectively avoiding the situation of water accumulation during the drainage process, and ensuring the timely drainage of rainwater in the water storage space 100.

[0050] In the implementation process, the size and position of the drain groove 10 can be appropriately adjusted according to the actual volume of the water storage space 100 and the amount of rainwater that needs to be drained. For example, for a large-capacity water storage space 100, the opening area of the drain groove 10 can be appropriately increased to ensure faster drainage speed; for a smaller water storage space 100, the drain outlet of the drain groove 10 can be designed to be adjustable to meet the needs under different precipitation conditions.

[0051] In addition, the material and surface treatment method of the drain groove 10 can also be selected according to the actual application scenario to ensure that it can resist corrosion and aging when exposed to outdoor environments for a long time, and maintain good drainage performance. Common materials such as stainless steel, plastic, or corrosion-resistant treated metals can meet this demand.

[0052] Based on the above, when the drain groove 10 drains the accumulated water in the water storage space 100, the water level in the water storage space 100 has dropped to the lowest, and the conduction state between the electrodes will change, and the electrodes will be in a non-conduction state. At this time, the control end does not collect the resistance signal, which indicates that the water level in the water storage space 100 has returned to the initial state and there is no continuous water accumulation. Therefore, the control end can determine that the external rainwater has stopped, thereby further adjusting the working state of the device.

[0053] In one embodiment, as shown in FIG. 1, the drain groove 10 is arranged at the bottom of the water storage space 100, and the drain groove 10 is connected to the water storage space 100 through a drain channel 12. Figure 2 Specifically, the drain groove 10 is designed to enable the accumulated water in the water storage space 100 to flow smoothly to the drain groove 10, avoiding the problem of water stagnation in the water storage space 100. Since the bottom of the drain groove 10 is flush with the bottom of the water storage space 100, it ensures that the water flow can pass through the drain channel unobstructed, effectively avoiding the situation of water accumulation during the drainage process, and ensuring the timely drainage of rainwater in the water storage space 100.

[0054] Specifically, the connection between the guide section 11 and the bottom of the water storage space 100 forms a communication channel, enabling the water flow to naturally flow along the inclined direction. The design of the inclination angle can be adjusted according to actual needs to optimize the speed and path of water flow discharge, ensuring effective drainage under various precipitation conditions.

[0055] In addition, the arrangement of the guide section 11 makes the water flow more concentrated, avoiding the dispersion of water flow in the water storage space 100, and further improving the utilization efficiency of the drainage channel.

[0056] In the specific implementation process, the inclination angle of the guide section 11 can be adjusted as needed to adapt to different precipitation amounts and water storage space 100 volumes. For example, for a smaller water storage space 100, the guide section 11 can be set to a larger angle to speed up the drainage of accumulated water; for a larger water storage space 100, the angle can be adjusted appropriately to achieve the best drainage effect.

[0057] The drawings accompanying the specification Figure 1 In the drawings of the present application, the number of drainage grooves 10 is set to two. In fact, in other embodiments, more, such as three, four, etc., can be provided. In the specific implementation process, the number and position of the drainage grooves 10 can be adjusted according to different equipment sizes and needs. For example, in smaller equipment, only two drainage grooves 10 may be needed, while in larger capacity equipment, the number of drainage grooves 10 can be increased to ensure faster drainage speed. The number and position of the drainage grooves 10 should be reasonably designed according to the actual precipitation amount and the volume of the water storage space 100.

[0058] At the same time, the drainage grooves 10 are symmetrically distributed on the peripheral wall of the main body 1. The symmetric distribution design of the drainage grooves 10 ensures that the accumulated water in the water storage space 100 can be uniformly discharged through multiple drainage channels, optimizing the water flow discharge path in the water storage space 100, so that the accumulated water can be quickly and uniformly discharged.

[0059] Through the cooperative work of multiple drainage grooves 10, the drainage speed can be improved, avoiding excessive accumulation of water in the water storage space 100 under heavy rainfall conditions, which affects the working state of the electrode. The symmetric distribution design makes the use of the drainage grooves 10 more uniform, reducing the poor drainage caused by the concentration of water flow on one side.

[0060] In one embodiment, the electrode assembly 2 includes at least three electrodes. To adapt to different liquid levels in the water storage space 100, at least two electrodes in the electrode assembly 2 have different heights. These electrodes sample different resistances through the conduction state of electrodes of different heights according to the change of the liquid level, thereby reflecting the accumulation of rainwater in the water storage space 100 and achieving accurate detection of rainfall changes.

[0061] Specifically, when the liquid level in the water storage space 100 changes, different electrodes in the electrode assembly 2 will sequentially or simultaneously enter a conductive or non-conductive state. Based on the conductivity of different electrodes, the control unit can collect the resistance changes between the electrodes in real time and determine the current rainfall status based on these resistance changes. For example, when the liquid level is low, only the lower-positioned electrodes are conductive; as the liquid level gradually rises, the higher-positioned electrodes begin to conduct, and the control unit can determine the amount of rainfall by comparing the conductivity states of different electrodes.

[0062] In addition, the multiple electrodes enable the device to cope with different rainfall intensities. Whether it is light rain or heavy rain, the system can accurately sense changes in rainfall by observing the conductivity of the electrodes, avoiding the misjudgment or delayed response problems that may be caused by traditional single-electrode designs.

[0063] It should be noted that, in practical applications, the number and height of electrodes in electrode assembly 2 can be adjusted according to the needs of different devices. For example, in smaller rainfall detection devices, only two or three electrodes may be needed, while for larger capacity devices, the number of electrodes can be further increased to improve the accuracy of rainfall detection.

[0064] Furthermore, based on the above embodiments, such as Figure 3 As shown, electrode assembly 2 includes three electrodes: a first electrode 21, a second electrode 22, and a high electrode. The first electrode 21 is the shortest electrode, the second electrode 22 has a height greater than or equal to the height of the first electrode 21 and is the first to conduct when the liquid level rises, and the high electrode has a height greater than the second electrode 22.

[0065] Meanwhile, to prevent the high electrode from being misactivated when there is little external precipitation (i.e., the first state), this application provides an insulating material 4 around the high electrode. Specifically, the height of the insulating material 4 around the high electrode is at least equal to the height of the second electrode 22. This is to prevent the high electrode from being misactivated when the water accumulation has not yet reached the height of the high electrode in the first state (i.e., a light rain environment with little external precipitation), thereby avoiding misjudging the state as heavy or moderate rain.

[0066] The number of high-level electrodes in this paper is not limited to one; multiple high-level electrodes can be set according to actual needs to adapt to different rainfall variations. For example, when the liquid level is low, the first electrode 21 and the second electrode 22 are connected, generating a specific resistance value, indicating that the external precipitation is small. As the liquid level rises, the first electrode 21 and the first high-level electrode are connected, generating a different resistance value, indicating that the external precipitation is large. As the rainfall increases, more high-level electrodes are connected to the first electrode 21. Based on the multiple resistance values ​​generated by the connected electrode combinations, the system can more accurately determine the precipitation status of heavy rain or torrential rain.

[0067] It can be understood that by adjusting the number of high electrodes, the device can determine different rain intensity changes through multiple resistance changes. Moreover, with the increase of the number of high electrodes, the system can support more rain intensity level determination, adapt to different use environments and needs. However, although the number of high electrodes can be increased to support multiple rain intensity determination, in order to avoid excessive number of electrodes leading to complex internal circuit, rising cost and difficult maintenance, the number of electrodes is still kept within a proper range, ensuring the simplicity and reliability of the system.

[0068] On the basis of the above embodiment, in one embodiment, the electrode assembly 2 includes four electrodes, specifically, the number of high electrodes is two, which are the first high electrode 23 and the second high electrode 24, the height of the second high electrode 24 is less than that of the first high electrode 23, and greater than that of the second electrode 22, thereby forming at least three electrodes of different heights in the detection device.

[0069] When the accumulated water in the water storage space 100 reaches a certain height and the first electrode 21 and the first high electrode 23 are conducted, the system forms a first specific resistance value for determining that the outdoor equipment is in a heavy rain environment. When the accumulated water in the water storage space 100 conducts the first electrode 21 and the second high electrode 24, the system forms a second specific resistance value for determining that the outdoor equipment is in a moderate rain or heavy rain environment. Similarly, when the accumulated water conducts the first electrode 21 and the second electrode 22, a third specific resistance value is formed, indicating a light rain environment.

[0070] By setting only four electrodes, the system can realize accurate rain intensity determination, while avoiding the complexity of excessive electrodes, ensuring the stability and easy maintenance of the equipment. Each pair of conducting electrodes can produce a unique resistance value, thereby realizing accurate precipitation intensity determination and ensuring that the equipment makes appropriate responses in different rain environments.

[0071] Although the current scheme uses four electrodes, by simply adjusting and increasing the number of electrodes, it can adapt to different liquid level detection needs, increase more rain intensity determination standards, and improve the flexibility of the device.

[0072] In one embodiment, the electrode assembly 2 is electrically connected to the control end by a wire, and the wire is made of weather-resistant material to ensure reliable connection in various weather conditions. The change of the conducting state detected by the electrode assembly 2 is transmitted to the control end through the wire, and the control end determines the strength of the rain according to different resistance values. When electrodes of different liquid levels are detected, the control end will determine that the current rainfall is in a light rain, moderate rain or heavy rain environment, and take corresponding measures accordingly.

[0073] Further, the rain detection device is equipped with a sealing structure, wherein the sealing structure at least partially wraps the control terminal, so as to ensure that the electrical components inside the control terminal are not affected by moisture, thereby adapting to the use requirements of the outdoor equipment under various environmental conditions.

[0074] Based on the above, the rain detection device can be used in combination with the outdoor equipment as shown in the accompanying drawings. Figure 1 The rain detection device further comprises a connecting portion 3, which is arranged at one end of the main body portion 1 and away from the opening of the water storage space 100, and is used for fixing the rain detection device to a predetermined position.

[0075] The connecting portion 3 can be a buckle structure, which can be used to connect the rain detection device to a predetermined position of the outdoor equipment, and then connect the rain detection device to the control terminal through wireless communication or wired communication, so as to control the start and stop of the outdoor equipment according to the rain intensity. Specifically, the buckle structure can include at least one pair of symmetrically distributed elastic clamping arms and a limiting protrusion matched with the elastic clamping arms. The inner side of the elastic clamping arm is provided with a guide slope, and the outer side is provided with an anti-dropping barb. The elastic clamping arm can be quickly clamped to the predetermined installation position of the outdoor equipment through the deformation restoring force without tools.

[0076] In one embodiment, the connecting portion 3 is integrated with a cable channel and / or a wireless communication module. When wired communication is used, the cable channel is embedded with a waterproof joint, and the shielded cable is used to realize electrical connection with the control terminal of the outdoor equipment. When wireless communication is used, for example, through a built-in Bluetooth module, the rain intensity level data is periodically sent to the control terminal. The control terminal dynamically adjusts the working mode of the outdoor equipment according to the received rain gradient signal (such as light rain, moderate rain, heavy rain level), including multi-level response strategies such as delay shutdown, power reduction operation or emergency power-off.

[0077] In one embodiment, according to another aspect of the present application, the present application further provides an outdoor equipment comprising the rain detection device according to any one of the above embodiments.

[0078] The outdoor equipment obtains the ratio relationship between the drainage speed and the water storage speed in the water storage space 100 through the electrode assembly 2 in real time. When the drainage speed is less than or equal to the water storage speed (second state), the operator or the terminal can determine that the working condition of moderate rain / heavy rain is entered and trigger the shutdown protection. When the drainage speed is greater than the water storage speed (first state), it is identified as a light rain environment and the equipment operation is maintained, thereby solving the rain misjudgment problem caused by water accumulation in the traditional device and avoiding the equipment from being incorrectly shut down under the condition of bearable light rain.

[0079] The drainage groove 10 arranged on the side wall of the main body part 1 extends along the height direction of the water storage space 100, forming a gradient drainage channel: when it is light rain, rainwater is quickly discharged through the drainage groove 10, and the electrode assembly 2 corresponds to the low liquid level state in the water storage space 100; when it is moderate or heavy rain, the liquid level rises to the electrode conduction threshold due to the insufficient flux of the drainage groove 10, so that the outdoor equipment can independently adjust the balance between storage and drainage according to the actual precipitation intensity, and the rainfall grading detection can be realized without additional sensors.

[0080] It should be noted that the above embodiments can be freely combined as needed. The above is only a preferred embodiment of the application, and it should be pointed out that for ordinary skilled persons in the art, without departing from the principles of the application, a number of improvements and refinements can be made, which should be considered as the protection scope of the application.
