Description

Technical Field

[0001] This application relates to the field of rainfall detection technology, and further to a detection device and outdoor equipment. Background Technology

[0002] Currently, commonly used outdoor rainfall detection devices typically consist of a water storage platform and two exposed electrodes. The electrodes determine whether rainfall has occurred based on changes in the water level. When rainwater accumulates to a certain level, a connection is formed between the electrodes, indicating the presence of rainfall and prompting the equipment to shut down. However, this type of device has a significant drawback: the water storage platform can only accumulate water and cannot drain it. For example, when the external rainfall is light but prolonged, the platform continuously accumulates water, causing the water level to rise and triggering electrode conductivity. This can lead to inaccurate rainfall readings, preventing the equipment from responding promptly to changes in the actual working environment and thus reducing the practicality and accuracy of the detection device. Utility Model Content

[0003] In view of the above-mentioned technical problems, the purpose of this application is to provide a detection device and outdoor equipment, which aims to solve the problem that the detection device in the prior art may produce erroneous detection results due to water accumulation.

[0004] To achieve the above objectives, this application provides a detection device installed in an outdoor device, comprising:

[0005] The water collection body has a water collection section and a guide slope. The water collection section is concave relative to the water collection body and is used to collect rainwater. The guide slope is provided on the upper surface of the water collection body and is connected to the water collection section, so that rainwater can be guided through the guide slope and then flow into the water collection section for rainfall detection.

[0006] At least two detection electrodes are spaced apart in the water collection section. After rainwater flows into the water collection section, at least part of the detection electrodes are submerged, so that the two corresponding detection electrodes are connected and generate a corresponding resistance value. The resistance value can change with the submerged area of ​​the detection electrodes to indicate the amount of rainfall.

[0007] A drainage structure is provided on at least one side or bottom of the water collection body and is connected to the bottom of the water collection part, so that rainwater in the water collection part can be discharged through the drainage structure to prevent water accumulation from causing false alarms in the detection device.

[0008] In some embodiments, the water collection section is located at the center of the water collection body, and the guide slope and the drainage structure are respectively centered on the water collection section and distributed around the water collection section, thus forming a ring array together.

[0009] In some embodiments, the guide slope includes a first slope and two second slopes, the first slope being directly opposite the opening of the water collection section and located between the two second slopes, wherein the slope of the first slope is greater than or less than the slope of any of the second slopes, the first slope being used to allow a portion of rainwater to flow into the water collection section at a first flow velocity, and the second slopes being used to allow a portion of rainwater to flow into the water collection section at a second flow velocity.

[0010] In some embodiments, a partition is provided between each of the second slopes and the adjacent drainage structure, the partition being used to prevent rainwater from flowing directly from the second slope into the drainage structure;

[0011] The partition portion has an inclined guide surface, which is located on the side of the partition portion near the water collection portion, for guiding at least a portion of the rainwater on the surface of the partition portion into the water collection portion.

[0012] In some embodiments, any one of the detection electrodes is not lower than the plane where the top of the water collection body is located;

[0013] And / or, the width of the drainage structure is less than or equal to half the width of the water collection section.

[0014] In some embodiments, the detection device further includes a plurality of water-breaking protrusions, which are disposed at the bottom of the water collection section and / or the drainage structure. When rainwater drips onto or flows through the water-breaking protrusions, the rainwater can be dispersed through the water-breaking protrusions to assist the flow of rainwater.

[0015] In some embodiments, the water-breaking protrusion is a cross-shaped column or a polygonal cone;

[0016] And / or, at least a portion of the water-breaking protrusions are arranged around the outer periphery of the detection electrode.

[0017] In some embodiments, the number of the guide slopes is at least two, the guide slopes are symmetrically distributed along the length of the water collection body, and the drainage structure is disposed between the ends of every two adjacent guide slopes.

[0018] In some embodiments, the water collection body is provided with two guide slopes and two drainage structures. The two drainage structures are arranged along the length of the water collection body and are located between the two guide slopes, thereby forming a cross-shaped flow path on the water collection body.

[0019] Another aspect of this application also provides an outdoor device, including: the above-described detection device, used to detect the rainfall in the working environment of the outdoor device;

[0020] The detection device can determine whether the outdoor equipment is in a first state or a second state based on the resistance value. In the first state, the drainage speed of the water collection section is greater than the water accumulation speed, which is used to determine that the outdoor equipment is in a light rain environment. In the second state, the drainage speed of the water collection section is less than or equal to the water accumulation speed, which is used to determine that the outdoor equipment is in a moderate rain environment or a heavy rain environment.

[0021] Compared with the prior art, the detection device and outdoor equipment provided in this application have at least the following beneficial effects:

[0022] By setting up a water collection body with a guiding slope, spaced detection electrodes, and a drainage structure connected to the water collection section, the rainfall of outdoor equipment in its working environment can be detected. The guiding slope helps to guide rainwater to flow into the water collection section quickly, improving the detection response speed; the detection electrodes generate different resistance values ​​under different immersion states, which can dynamically reflect the intensity of rainfall and enhance the accuracy of detection; the drainage structure effectively prevents rainwater from accumulating for a long time and avoids misjudgment caused by continuous water accumulation in light rain, effectively improving the practicality and reliability of the detection device.

[0034] Currently, commonly used rainfall detection devices in outdoor equipment typically include a water storage platform and two exposed detection electrodes. The presence of precipitation is determined by whether rainwater is present between the electrodes. When precipitation occurs and the water level on the storage platform reaches a certain level, a conductive loop is formed between the two electrodes, thus confirming the presence of rainfall and indicating whether the equipment needs to enter a shutdown protection state.

[0035] However, existing devices generally lack drainage structures, making it difficult to drain rainwater in a timely manner once it accumulates. Especially when the external rainfall is light but prolonged, rainwater gradually accumulates in the water storage platform, eventually reaching the liquid level threshold that triggers electrode conduction. Even if the actual rainfall is not significant, it may be misjudged as heavy rainfall, causing equipment to stop erroneously or experience response delays, severely affecting the accuracy of detection and the rationality of equipment operation.

[0036] In one embodiment, refer to the appendix to the specification. Figure 1 The present application describes a detection device that can detect rainfall while avoiding false alarms due to rainwater retention.

[0037] Reference manual attached Figure 1 The present application provides a detection device for outdoor equipment, including a water collection body 1, a detection electrode 30, and a drainage structure 40.

[0038] The water collection body 1 is installed on the surface of the outdoor equipment or its compatible part to collect external rainfall. The water collection body 1 has a water collection section 10 and a guide slope 20. The water collection section 10 is concave relative to the water collection body 1 to facilitate the collection of rainwater. The guide slope 20 is provided on the upper surface of the water collection body 1 and is connected to the water collection section 10. It can effectively guide the rainwater falling on the guide slope 20 into the water collection section 10, thereby improving the water collection efficiency and shortening the response time of rainwater entering the detection area.

[0039] At least two detection electrodes 30 are spaced apart and disposed inside the water collection section 10. After rainwater enters the water collection section 10, the detection electrodes 30 are partially or completely submerged, forming an electrical connection and generating a corresponding resistance value. By measuring different resistance values, the rainwater level can be determined, thus reflecting the intensity and duration of rainfall. This design can not only detect whether rainfall has occurred but also dynamically respond to changes in rainfall, enhancing the accuracy of detection and environmental adaptability.

[0040] More importantly, to prevent rainwater from accumulating in the water collection section 10 for a long time and causing continuous flow that could lead to misjudgment, the water collection body 1 is also equipped with a drainage structure 40. The drainage structure 40 is located on at least one side or bottom of the water collection body 1 and is connected to the bottom of the water collection section 10, which enables rainwater to be discharged in a timely manner after detection, preventing abnormal rise in liquid level.

[0041] The drainage structure 40 can be a drainage hole, drainage trough, or similar drainage channel. In this embodiment, no specific limitation is made, and it can be flexibly configured according to the usage scenario and the relevant structure of the outdoor equipment.

[0042] Understandably, compared to traditional detection schemes, this detection device in this embodiment can achieve more accurate rainfall identification, effectively avoid false triggering caused by continuous water accumulation during light rain, and significantly improve the reliability and practicality of the detection device in complex outdoor environments.

[0043] It should be noted that, specifically, when the outdoor equipment is in light rain, rainwater gradually falls into the water collection section 10. Due to the low rainfall intensity, the amount of rainwater accumulated per unit time is limited. At this time, the drainage structure 40 may drain water at a rate greater than the water collection rate, resulting in the water level in the water collection section 10 remaining at a low level. The resistance value between the detection electrodes 30 remains in a relatively high range. By continuously collecting the resistance value change data, the control terminal can determine whether there is light rainfall or no significant water accumulation, thus avoiding triggering false alarms.

[0044] When the rainfall intensifies into moderate or heavy rain, the rate at which rainwater flows into the collection section 10 increases significantly, exceeding the drainage capacity of the drainage structure 40. This causes the water level to rise continuously, increasing the contact area between the rainwater and the detection electrode 30. Consequently, the system resistance value decreases, and the obtained resistance value can be compared with the preset multi-level resistance reference value to identify different intensity levels of rainfall.

[0045] Based on the design of this embodiment, in other alternative embodiments, the outer periphery of the detection electrode 30 can be further covered with an insulating structure to partially shield its conductive area. The insulating structure is preferably made of an electrically insulating material, possessing a certain thickness and weather resistance, capable of covering the electrode surface so that the electrode only contacts and conducts electricity in partially exposed areas. By adjusting the covering height or area of ​​the insulating structure, different triggering conditions can be effectively created, thereby forming a multi-level resistance response based on the liquid level height.

[0046] For example, by setting up multiple detection electrodes 30 and covering them with insulating material at different heights, when the rainwater level is low, only some of the lower-level electrodes are conductive. As the level rises, more electrode areas are gradually exposed and come into contact with the rainwater, creating multi-level resistance changes. This structural design helps improve detection resolution, enabling the device not only to determine whether it is raining but also to identify different levels of rainfall intensity, thereby enhancing the accuracy and adaptability of the overall monitoring system.

[0047] In addition, the insulation structure can also protect areas of the detection electrode 30 that may be affected by external impurities, moisture, or splashing water, further enhancing the environmental stability and anti-false alarm capabilities of the device. Meanwhile, the drainage structure 40 can be equipped with a filter to block debris, improving the long-term stability and ease of maintenance of the device.

[0048] Based on the above embodiments, in one embodiment, refer to the appendix to the specification. Figure 2Each detection electrode 30 is not lower than the top plane of the water collection body 1. That is, the setting height of all detection electrodes 30 is higher than or at least level with the reference horizontal plane of the upper surface of the water collection body 1, thereby ensuring that rainwater can make effective contact with at least one set of detection electrodes 30 when it reaches any liquid level in the water collection part 10, thereby achieving accurate detection of different liquid level states.

[0049] Understandably, through the configuration of this embodiment, not only can the detection electrode 30 cover the maximum liquid level range that the entire water collection space may reach, but it also ensures that the device can identify various working conditions, including initial water accumulation during light rain, stable water accumulation during moderate rain, and rapid rise in liquid level during heavy rain, in the actual working process, thereby achieving full-process and full-threshold rainfall recognition capability.

[0050] In one embodiment, please refer to the appendix to the specification. Figure 1 and Figure 3 The water collection section 10 is located at the center of the water collection body 1 and is used to collect rainwater that gathers from the outside. Around the outer periphery of the water collection section 10, multiple guide slopes 20 and drainage structures 40 are provided. The guide slopes 20 and drainage structures 40 are arranged along a ring path, for example, alternating with each other or arranged in a certain pattern, together forming a ring array.

[0051] The guide slope 20 extends inward from the periphery of the water collection body 1 and is directly connected to the water collection section 10 to guide rainwater into the water collection area; the drainage structure 40 is located adjacent to the guide slope 20 and is also connected to the water collection section 10 to drain the water accumulated at its bottom in a timely manner.

[0052] Understandably, this embodiment forms a ring-shaped layout around the water collection section 10, meaning that the drainage and flow paths are coordinated within the outer ring area of ​​the water collection section 10, allowing the water collection and drainage processes to be spatially distributed in an orderly manner. This effectively improves the overall rainwater runoff efficiency while maintaining smooth drainage, avoiding problems such as uneven water collection or delayed drainage.

[0053] In a preferred embodiment, the guide slope 20 can be a wedge-shaped or fan-shaped area, which is inclined from the outer edge inward. Its inner edge is connected to the water collection part 10, and its outer edge is higher than the plane where the water collection part 10 is located. The drainage structure 40 can be a drainage hole or a thin pipe, one end of which is also connected to the periphery of the water collection part 10, and the other end can lead to the drainage channel or external water storage module at the bottom of the water collection body 1.

[0054] The number, spacing, and sequence of the aforementioned diversion slope 20 and drainage structure 40 can be adjusted according to specific usage requirements. For example, they can be set as uniformly distributed repeating segments of "diversion slope 20 - drainage structure 40 - diversion slope 20" to facilitate modular structural design.

[0055] In one embodiment, further, such as Figure 1 As shown, the guide slope 20 further includes a first slope 201 and two second slopes 202. The first slope 201 faces the opening of the water collection section 10 and is positioned between the two second slopes 202. The three together form an integrated guide unit. The slope of the first slope 201 is greater than that of the two second slopes 202, meaning the inclination angle of the first slope 201 is relatively steeper. This allows rainwater falling on its surface to slide down quickly at a first flow velocity and flow into the water collection section 10. The two second slopes 202, due to their gentler slopes, allow rainwater to enter the water collection section 10 at a second flow velocity, which is relatively lower. In other words, the first flow velocity is greater than the second flow velocity.

[0056] Through the above structural design, the rainwater diversion path is graded and diverted, that is, some rainwater can flow into the water collection section 10 via a fast path to form an initial liquid level, while the other part of the rainwater is gradually introduced via a slow path to achieve a stable increase in the liquid level. This effectively regulates the rhythm of rainwater entering the water collection section 10, avoids a sudden rise in liquid level caused by a large amount of rainwater rushing in in a short period of time, and improves the stability of the response of the detection electrode 30 and the accuracy of rainfall judgment.

[0057] Understandably, since the first slope 201 and the second slope 202 control different water flow paths, the system can quickly form a conduction signal in the initial response stage of rainwater, while the second slope 202 slowly replenishes rainwater, which improves the overall detection device's ability to identify the intensity and duration of rainfall.

[0058] In practical implementation, the first slope 201 and the second slope 202 can be integrally formed on the upper surface of the water collection body 1. Their surfaces can be provided with drainage grooves to further guide the water flow direction and enhance drainage efficiency. Furthermore, to adapt to the rainfall characteristics of different areas, the slope parameters, length ratios, and position angles of the first slope 201 and the second slope 202 can be flexibly configured according to actual working conditions.

[0059] In contrast to the previous embodiment, in another embodiment, the slope of the first slope 201 is less than the slope of the two second slopes 202, and the first flow velocity is less than the second flow velocity; in other words, the first slope 201 is relatively gentle, while the second slopes 202 on both sides are relatively steep.

[0060] Understandably, the first slope 201 serves as a guide path directly facing the water collection section 10. Its gentler slope allows rainwater falling in this area to enter the water collection section 10 at a slower and more stable flow rate, which helps to achieve precise control of rainwater flow and effectively avoids false alarms caused by rainwater directly impacting the detection electrode 30, thereby enhancing the stability of the detection results.

[0061] The two second slopes 202, due to their greater gradient, primarily serve a rapid diversion function. In other words, the second slopes 202 can quickly divert rainwater from the edge areas to the collection section 10, thereby improving collection efficiency to some extent and assisting in responding to rapid changes in liquid level.

[0062] Based on the above embodiments, in one embodiment, such as Figure 1 As shown, each second slope 202 is provided with a partition 50 between it and the adjacent drainage structure 40. The partition 50 acts as a physical barrier between the second slope 202 and the drainage structure 40, preventing rainwater from sliding directly into the drainage structure 40 and being prematurely discharged before flowing into the water collection section 10. This partition structure ensures that rainwater falling into the second slope 202 is preferentially guided into the water collection section 10, effectively enhancing the continuity and controllability of liquid level accumulation.

[0063] The partition 50 is preferably a protruding structure with a certain height and width, which is distributed in a regular manner along the outer edge of the water collection part 10, and works in conjunction with the arrangement of the second slope 202 to achieve intermittent water blocking.

[0064] Furthermore, to prevent rainwater from accumulating in the partition 50, an inclined guide surface 501 is provided on the side near the water collection section 10. This inclined guide surface 501 is arranged in an inward inclined manner, that is, inclined towards the water collection section 10, so that the rainwater received on the surface of the partition 50 can be guided into the water collection section 10, forming a smooth flow path. This not only solves the water storage problem caused by the partition, but also enhances the efficiency of recovering small amounts of rainwater.

[0065] Understandably, through the design of this embodiment, on the one hand, the partition 50 blocks the path of rainwater flowing directly from the second slope 202 into the drainage structure 40, enabling the system to collect rainfall more completely and improving the detection capability of low-intensity precipitation such as light rain and drizzle; on the other hand, the setting of the inclined guide surface 501 ensures that the partition 50 itself does not become a water accumulation hazard, but effectively guides the rainwater received on its surface back into the water collection part 10, thereby improving the closed-loop performance and rainwater utilization efficiency of the overall water guiding system.

[0066] In different application scenarios, the partition 50 can be modified according to actual needs. For example, its shape can be arc-shaped, wedge-shaped, or trapezoidal. It can be integrally injection molded with the water collection body 1 or assembled using a modular snap-fit ​​method, which facilitates maintenance and replacement. The angle and surface treatment of the inclined guide surface 501 can also be optimized and adjusted according to the precipitation characteristics of the area. For example, a hydrophobic coating or flow channel texture can be applied to enhance the rainwater guiding effect.

[0067] In one embodiment, the width of the drainage structure 40 is less than or equal to half the width of the water collection section 10. By limiting the structural proportions, the drainage structure 40 has effective drainage capacity without being too wide, which would cause rainwater in the water collection section 10 to drain out too quickly, thus affecting the stability and accuracy of rainfall detection.

[0068] The key to this embodiment lies in achieving a balance between drainage efficiency and detection sensitivity. Specifically, if the drainage structure 40 is too wide, rainwater in the water collection section 10 may be discharged before it can effectively submerge the detection electrode 30, resulting in the device being unable to form an effective conduction resistance, leading to delays or misjudgments in the rainwater signal detection. On the other hand, if the drainage structure 40 is set too narrow, it may cause rainwater to stagnate, reducing drainage efficiency, and even causing false alarms or excessive alarms due to a continuously high liquid level.

[0069] Thus, by limiting the width of the drainage structure 40 to a certain proportion (e.g., half or less) of the width of the water collection section 10, it is possible to ensure that the detection electrode 30 remains submerged for a sufficient time within the effective liquid level range while ensuring the basic drainage function, so that the system can identify the change process of the rainfall based on the continuous change of the resistance value.

[0070] In one embodiment, combined Figure 1 and Figure 3 As shown, the detection device also includes several water-breaking protrusions 60, which are disposed at the bottom of the water collection section 10 and / or the drainage structure 40. When rainwater drips directly onto the water-breaking protrusions 60, or flows over their surface, it can be effectively dispersed into multiple water flow units under the disturbance effect of the water-breaking protrusions 60, thereby changing the state of the continuous water film or concentrated water column that it might have formed, which is conducive to the smoother flow and diffusion of rainwater inside the detection device.

[0071] It should be noted that the structural design in this embodiment mainly improves water collection or drainage efficiency and stabilizes the distribution of rainwater on the surface of the water collection section 10 by intervening in the natural adhesion path of the water flow through microstructures. Especially in scenarios with low rainfall or strong water adhesion, rainwater often moves slowly along the bottom surface due to surface tension, or even stagnates locally, affecting its coverage distribution in the area where the detection electrode 30 is located.

[0072] The water-breaking protrusion 60 in this embodiment can physically "break" the continuity of water flow, prompting rainwater to spread and be guided to the vicinity of the detection electrode 30 more quickly, thereby improving the transmission efficiency of rainwater signals and enhancing the sensitivity of detection response.

[0073] Furthermore, the water-breaking protrusions 60 can be configured as several regularly or irregularly arranged protrusions. In addition, the spacing and size between the water-breaking protrusions 60 can be flexibly determined according to the geometric characteristics of the water collection section 10 or the drainage area. For example, densely arranged small protrusions in the central area of ​​the water collection section 10 help to enhance the local turbulence effect; while larger protrusions are arranged in the drainage structure 40 area to stabilize the water flow rhythm and prevent water flow turbulence.

[0074] In addition, the water-breaking protrusion 60 can be further optimized by combining material selection, such as using a hydrophobic coating, so that rainwater can break and roll on the surface more easily rather than linger, effectively preventing water accumulation or stain adhesion, thereby improving the long-term stability and self-cleaning ability of the detection device.

[0075] Please refer to the instruction manual attached. Figure 3 At least some of the water-breaking protrusions 60 are arranged around the outer periphery of the detection electrode 30. On the one hand, this prevents rainwater from forming a water film layer with strong surface tension around the electrode, thus preventing local water accumulation from affecting the accuracy of the resistance response between the electrodes. On the other hand, it also helps to guide rainwater to cover the detection area more quickly and fully, improving the sensitivity of liquid level identification under different rainfall intensities. Especially in cases of light rainfall and limited water accumulation, the surrounding arrangement of water-breaking protrusions 60 can significantly improve the local disturbance capability of the catchment area, enhance the ability to identify initial rainfall, and prevent response delays caused by the lag of small amounts of water accumulation.

[0076] In a further optimization, the aforementioned water-breaking protrusions 60 can be arranged in a regular manner according to the geometry of the water collection section 10, forming a single or multiple array structure. The arrangement direction is set in combination with the slope inclination direction, so that rainwater will come into contact with the water-breaking protrusions 60 multiple times during the flow process, thereby ensuring that they form a dynamic flow inside the device and fully contact the detection area, improving the response range and accuracy of the device in various scenarios such as light rain, light rain to heavy rain.

[0077] Based on the above embodiments, in an optional embodiment, the water-breaking protrusion 60 is a cross-shaped column, such as the arrangement shown in the attached figures, or a polygonal cone structure (not shown in the attached figures). This type of configuration maintains a moderate protrusion height while possessing strong turbulence-disrupting capabilities.

[0078] Among them, the cross-shaped column, due to its intersecting edge structure, can quickly disperse the concentrated flow pattern of rainwater upon contact, causing the rainwater to flow in multiple directions, which helps to achieve rapid spreading and uniform diffusion. The polygonal cone structure, through its multiple inclined surfaces, creates disturbance at the point of rainwater impact, causing the water flow to exhibit a natural branching tendency, further improving the efficiency of rainwater film breaking and diversion.

[0079] In one embodiment, the number of guide slopes 20 is at least two, preferably an even number, and the guide slopes 20 are symmetrically distributed along the length of the water collection body 1, so that each guide slope 20 is a mirror image of the water collection section 10. This arrangement helps to improve the overall symmetry and structural balance of the water collection body 1, and can ensure that precipitation is uniformly guided into the water collection section 10 in actual environments with multi-directional and multi-angle rainfall, preventing the risk of uneven distribution of rainwater in the water collection area due to structural offset, thereby causing detection delays or misjudgments.

[0080] Furthermore, a drainage structure 40 is provided between the ends of each pair of adjacent guide slopes 20. That is, with the water collection part 10 as the center, multiple guide slopes 20 and drainage structures 40 are alternately arranged in the direction of the guide slopes 20 on its outer periphery, so that the guide slopes 20 and drainage structures 40 are arranged in an alternating manner around the water collection part 10.

[0081] It is understandable that the configuration of this embodiment not only enhances the multi-directional flow capability of the water collection section 10, but also improves the efficiency of rainwater dispersion and discharge, so that the water collection section 10 can maintain a dynamically adjustable liquid level balance range under different rainfall conditions, which makes it convenient for the detection system to use the resistance value as the identification standard to judge the rainfall in real time.

[0082] Through the above structure, rainwater flows rapidly into the water collection section 10 along the slope when passing through the guide slope 20. When the water in the water collection section 10 gradually rises to a set threshold, excess rainwater can be discharged through the drainage structure 40 set between the guide slopes 20, thereby avoiding the continuous rise of the liquid level and causing erroneous conduction. In addition, since the drainage structure 40 and the guide slope 20 are not centrally arranged, but distributed symmetrically, it can prevent the problem of unstable water level in the detection area caused by excessive flow velocity in the drainage path, and ensure that a stable and identifiable liquid level resistance change is formed between the detection electrodes 30.

[0083] In practice, the guide slope 20 can be flat, arc-shaped or curved, and its surface roughness or surface treatment can be optimized according to the surface tension of rainwater to improve the sliding speed of rainwater.

[0084] Based on the above embodiments, in an optional embodiment, referring to the accompanying drawings, the water collection body 1 is provided with two guide slopes 20 and two drainage structures 40. The two guide slopes 20 are respectively arranged along the width direction of the water collection body 1, and the two drainage structures 40 are arranged along the length direction of the water collection body 1 and positioned between the two guide slopes 20. Through this arrangement, the guide slopes 20 and drainage structures 40 are staggered and symmetrically arranged, so that the overall structure together forms a cross-shaped rainwater flow path on the surface of the water collection body 1.

[0085] Two guide slopes 20 are located on both sides of the water collection body 1 and are inclined toward the water collection section 10 to guide rainwater falling onto their surface in the width direction to the water collection section 10 in the middle; while two drainage structures 40 run through the guide slopes 20 and are located in the length direction of the water collection body 1, so that when rainwater accumulates to a certain height, excess water can be smoothly discharged along the length direction.

[0086] Understandably, through the configuration of this embodiment, not only are two sets of orthogonal water flow channels formed structurally to achieve the coordination of flow guidance in the width direction and drainage in the length direction, but the dynamic distribution and discharge path of rainwater in different directions are also optimized functionally, so that rainwater can be quickly collected and discharged in a timely manner within a limited device volume.

[0087] Furthermore, this design achieves superior water collection and drainage efficiency with a smaller number of diversion and drainage components, thanks to a rational geometric distribution and functional path planning. This simple structure, fewer components, and centralized layout significantly simplify the processing and assembly of the device, reducing manufacturing costs.

[0088] In one embodiment, according to another aspect of this application, this application further provides an outdoor device including the detection device in any of the above embodiments, for detecting the rainfall in the working environment of the outdoor device, and can effectively prevent rainwater from accumulating for a long time through the setting of the drainage structure 40, avoiding misjudgment caused by continuous water accumulation due to light rain.

[0089] The detection device can determine whether the outdoor equipment is in a first state or a second state by measuring the resistance value. In the first state, the drainage speed of the water collection part 10 is greater than the water accumulation speed, which is used to determine whether the outdoor equipment is in a light rain environment. In the second state, the drainage speed of the water collection part 10 is less than or equal to the water accumulation speed, which is used to determine whether the outdoor equipment is in a moderate rain environment or a heavy rain environment.

[0090] Specifically, the detection device determines the current rainfall status of the equipment by measuring the resistance value between the detection electrodes 30 and combining this with the dynamic balance between water accumulation and drainage. Preferably, the detection device is equipped with a signal module that communicates with the main control unit. When a change in the immersion state of the detection electrodes 30 causes a change in the resistance value, the signal module can send a corresponding value to the main control unit as a basis for judgment.

[0091] In the first state, since the drainage structure 40 can drain rainwater in time, the electrode immersion area is limited and the resistance value changes little. Based on this, the main control unit can determine that the equipment can continue to work without protection or shutdown. In the second state, as the liquid level rises, the electrode is gradually submerged and the resistance value shows a significant downward trend. Based on this, the main control unit can trigger a shutdown command or enter the protection mode to prevent outdoor equipment from being damaged by harsh environments.

[0092] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
