Description

Technical Field

[0001] The invention relates to the technical field of outdoor distribution boxes, and in particular to a rainwater sensing alarm device for an outdoor distribution box. Background Art

[0002] Existing rain sensors for outdoor distribution boxes are mainly used to detect whether there is precipitation on the top of the distribution box. They are usually installed on the top or side of the distribution box, and trigger alarms or take corresponding protective measures by sensing the presence of rain. The working principles of these sensors are generally based on the principles of resistance change or capacitance change. Their basic function is to detect the arrival of rain by utilizing the physical changes of sensing sheets, sensing elements or electrodes when they come into contact with rain. The sensing elements in the rain sensors, such as the resistor sensing sheets, can maintain a high resistance value in the absence of rain, and when rain falls on the sensing sheets, the resistance will change due to the conductivity of water, and this change can be detected by the sensor.

[0003] In the prior art, many outdoor distribution boxes are equipped with rain sensors on top. These sensors are mainly used to detect the occurrence of precipitation and to warn or protect equipment from the direct impact of rain by sounding an alarm or taking protective measures. However, these traditional rain sensors are mostly focused on monitoring the presence of rain, and do not consider the control and management of moisture inside the distribution box. In extreme weather conditions such as rainstorms and heavy rains, although the rain sensor can identify precipitation in a timely manner, it cannot effectively prevent external rainwater from penetrating into the distribution box or avoid the accumulation of moisture caused by it. Typically, these rain sensors are not designed with additional protective measures to deal with moisture problems, and the accumulation of moisture is often ignored until the internal equipment of the distribution box fails or is damaged, and the problem is exposed.

[0004] Since rain sensors are limited to monitoring precipitation and ignore the impact of moisture on the internal environment of the distribution box, the penetration of external rainwater will cause the humidity inside the distribution box to increase, which in turn has a serious impact on the internal electronic components, lines and equipment. A continuous humid environment not only increases the risk of electrical failures and short circuits, but may also cause equipment corrosion, aging, and even cause serious safety hazards such as fire. In addition, if the distribution box is in a humid environment for a long time, the service life of the distribution box will be greatly shortened, and the frequency of repairing and replacing equipment will increase, resulting in higher maintenance costs. Therefore, the existing technology has failed to effectively solve the problem of moisture accumulation and protection in the distribution box, and further improvement and innovation are needed to take effective moisture-proof measures to improve the overall safety and reliability of the distribution box. Summary of the invention

On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully conveyed to those skilled in the art.

[0020] like Figures 1 to 15 As shown, an embodiment of the present invention provides a rainwater sensing alarm device for an outdoor distribution box, comprising: a housing 1 and a box seat 2 arranged below the housing 1, a cabinet door 3 is rotatably provided at the front end of the housing 1, a top cover 4 is fixedly provided above the housing 1, and further comprising: The rainwater sensing assembly 5 includes: a rainwater sensing box 501, which is fixed on the top cover 4 and has four chamfered sides; a resistance sensing sheet 502, which is fixed on the top of the rainwater sensing box 501 and is used for detecting the falling of rainwater; a trigger sensing sheet 503, which is fixed on the four chamfered sides of the top of the rainwater sensing box 501; a heating resistance sheet 504, which is fixed in the rainwater sensing box 501 and is used for heating the resistance sensing sheet 502; The induction protection component 7 includes: a limit rail seat 701, which is fixed above the top cover 4 and fixed to the outside of the rainwater sensor box 501; a protection slide cover 702, which slides on the limit rail seat 701 and has a silicone scraper 703 fixed inside for protecting the rainwater sensor component 5; The box protection component 8 includes: a closed blade 801, which has a plurality of closed blades 801 arranged at equal intervals, and the plurality of closed blades 801 rotate on both sides of the housing 1 to protect the distributor in the housing 1 and to play a role in heat dissipation; The dehumidification component 9 includes: a silica gel dehumidification cylinder 901, fixed on the inner side of the shell 1, for absorbing moisture from the outside air entering the shell 1; a heating tube 902, fixed on the inner side of the shell 1, for heating the gas in the shell 1; and a two-way air pump 903, fixed on the inner side of the box base 2.

[0021] A distribution rack 101 is fixed on the inner side of the outer shell 1, a temperature and humidity sensor 102 is fixed on the inner side of the outer shell 1, and a functional square tube 103 is fixed on the inner side of the outer shell 1. Two functional square tubes 103 are arranged, which are located on both sides of the outer shell 1. A heat dissipation hole 104 is opened on the outer side of the outer shell 1, and a ventilation hole 105 is opened on the outer side of the outer shell 1; an inclined block 505 is fixed on the outer side of the rain sensor box 501; a handle 6 is fixed on the outer side of the cabinet door 3; a mesh 9017 is fixed on the inner side of the silica gel dehumidification tube 901.

[0022] Specifically, the resistance sensing sheet 502 is a resistive sensing sheet, which is usually composed of two electrodes. The resistance value between them will be affected by moisture. When rain drops onto the surface of the resistance sensing sheet 502, water molecules enter between the electrodes. Water has a certain conductivity, which will cause the resistance value to change. The water droplets enhance the conductivity between the electrodes, thereby reducing the resistance; this changed resistance value can be detected by the sensor; the limit slide rail seat 701 facilitates the sliding of the protective slide cover 702. The design of the protective slide cover 702 is mainly to prevent rain from directly contacting the rain sensor box 501, thereby avoiding the influence of rain on the sensor box and reducing its service life.

[0023] The chamfered design of the four corners on the top of the rain sensor box 501 has important functional advantages, especially in improving the sensing effect when it rains; the chamfered design is not only for aesthetics, but also for optimizing the flow of rainwater, ensuring that an electric bridge can be quickly and effectively formed between the two electrodes of the trigger sensor sheet 503, thereby triggering the operation of the system switch.

[0024] The trigger sensing sheet 503 is composed of two electrodes. Using the bridge principle, when rain drops onto the trigger sensing sheet 503, they form a bridge, allowing current to flow, thereby triggering a switch signal. The switch signal activates the protective slide 702 to cover the rain sensing box 501, triggering the heating resistor 504 to heat the resistor sensing sheet 502, evaporating the moisture on the outer surface of the evaporating resistor sensing sheet 502 until the resistance value of the resistor sensing sheet 502 returns to a normal state, so as to ensure the long-term reliability and accuracy of the resistor sensing sheet 502, and then triggers the opening and closing of the closed leaf plate 801 through the movement trajectory of the protective slide 702.

[0025] The silica gel dehumidification cylinder 901 is filled with water-absorbent silica gel; the air in the housing 1 is replaced by a two-way air pump 903.

[0026] The temperature and humidity sensor 102 is used to detect the temperature and humidity in the housing 1 , and the heat dissipation holes 104 are used to circulate the gas in the housing 1 .

[0027] In the actual application of this embodiment: a processing system is set up inside the outdoor distribution box to process the operation of the rain sensing component 5, the sensing protection component 7, the box protection component 8 and the dehumidification component 9; the system can be connected to the network to monitor the working status in the distribution box in real time, and issue an alarm through the network when an abnormality occurs; the network alarm will be triggered under the following conditions: when the rain sensing component 5 fails to detect the precipitation sensing protection component 7 and the box protection component 8 in time and cannot effectively start the protection measures, or the dehumidification component 9 fails to remove moisture normally; if the humidity inside the distribution box exceeds the set threshold, or the equipment fails, the system will automatically issue an alarm to remind relevant personnel to handle it in time.

[0028] When the resistor sensing sheet 502 detects rain, the system will send out an alarm notification through the network; rain drops onto the surface of the resistor sensing sheet 502, and water has a certain conductivity, causing the resistance value to change, thereby detecting whether it is raining; the two electrodes of the trigger sensing sheet 503 are connected by rain, and the rain is used as a bridge to allow current to flow, turning on the heating resistor sheet 504 for heating.

[0029] The present invention triggers the electrode of the sensing sheet 503 through rainwater communication, turns on the heating resistor sheet 504 to heat the resistance sensing sheet 502, and quickly evaporates the water on the resistance sensing sheet 502, which can effectively prevent the water from being retained on the surface of the sensing sheet for a long time, reduce the interference of the water on the sensor performance, and ensure that the sensing sheet can work continuously and accurately; at the same time, the protective sliding cover 702 covers the rainwater sensing box 501, and uses the heat dissipation motor 707 and the heat dissipation fan 708 to bring the water vapor out of the protective sliding cover 702.

[0032] A second air hole 7012 is provided on the inner side of the protective sliding cover 702, and the second air hole 7012 is located at the end away from the silicone scraper 703.

A travel groove 7014 is provided below the protective sliding cover 702, and the travel groove 7014 is located at the end away from the silicone scraper 703.

[0033] Specifically, when the heating resistor 504 heats the resistor sensing sheet 502, the heat dissipation motor 707 and the heat dissipation fan 708 are turned on to evaporate the moisture on the resistor sensing sheet 502. The formed water vapor is effectively discharged from the first air vent 7010 to prevent water vapor accumulation during the heating process and to prevent the water vapor from condensing and forming water droplets that return to the outer surface of the resistor sensing sheet 502.

[0034] In actual application of this embodiment: the heating resistor 504 heats the moisture on the outer surface of the resistor sensing plate 502, and the moisture evaporates to form water vapor. In order to prevent the water vapor from gathering at the top of the protective sliding cover 702, the airflow formed by the rotation of the cooling fan 708 is used to discharge the water vapor from the protective sliding cover 702.

[0035] The present invention drives the threaded rod 705 to rotate through the protection motor 704 and the transmission gear pair 706, drives the protection slide cover 702 to move toward the rainwater sensing box 501, and effectively scrapes the moisture on the resistance sensing sheet 502 and the trigger sensing sheet 503 through the silicone scraper 703, removes most of the moisture on the surface of the resistance sensing sheet 502 and the trigger sensing sheet 503, ensures that the resistance sensing sheet 502 and the trigger sensing sheet 503 can quickly restore their normal working state, and maintain sensitivity and accuracy.

[0040] The dehumidification component 9 also includes: a temperature sensor 9014, which is fixed on the inner side of the functional square tube 103 and is located below the heating tube 902; a first air pipe 9015, one end of which is fixed below the functional square tube 103, and the other end is fixed on the two-way air pump 903, and is located inside the box seat 2; a second air pipe 9016, one end of which is fixed on the two-way air pump 903, and the other end extends out of the inclined bottom plate 9011, and is located inside the box seat 2.

[0041] Specifically, the magnetic piston 908 is composed of a piston and a permanent magnet. The permanent magnet is placed inside the piston. The top of the inclined bottom plate 9011 is set at an inclined surface. When there is water at the bottom of the outdoor distribution box, it is convenient for the water to flow and collect in the water collecting box 9012, and then drain out from the water pipe 9013. The four induction coils 9010 sense the position of the magnetic piston 908, and the temperature sensor 9014 is used to detect the temperature inside the functional square cylinder 103.

[0044] Working principle: When it is not raining, the protective sliding cover 702 is separated from the rain sensor box 501, and the rain sensor box 501 senses in real time whether it is likely to rain.

[0045] When it rains, rain falls to the top of the rain sensor box 501 and falls on the resistor sensing sheet 502 and the trigger sensing sheet 503. The resistance value of the resistor sensing sheet 502 changes to sense rain. The rain connects the two electrodes of the trigger sensing sheet 503 to turn on the heating resistor sheet 504 to heat the resistor sensing sheet 502. The heating resistor sheet 504 can quickly evaporate the moisture on the resistor sensing sheet 502.

[0046] During the heating process of the heating resistor 504, the protection motor 704 is started, and the rotation of the protection motor 704 drives the rotation of the transmission gear pair 706, and the rotation of the transmission gear pair 706 drives the rotation of the threaded rod 705. The rotation of the threaded rod 705 drives the protection slide cover 702 to slide along the limiting slide rail seat 701, and the protection slide cover 702 moves toward the direction of the rainwater sensor box 501 until the limiting groove 7013 of the protection slide cover 702 moves to the limiting block 709, so that the protection slide cover 702 and the limiting slide rail seat 701 are combined to completely cover the rainwater sensor box 501, and when it rains again, the rainwater sensor box 501 is protected.

[0047] When the protective sliding cover 702 covers the rainwater sensing box 501, the silicone scraper 703 is used to scrape water from the resistance sensing sheet 502 and the trigger sensing sheet 503. The scraped water flows from the rainwater sensing box 501 to the inclined block 505, and then is discharged from the drainage groove 7011 by the inclined block 505. A large amount of water on the resistance sensing sheet 502 and the trigger sensing sheet 503 can be removed, which is convenient for rapid evaporation of water. When there is no rain to trigger the trigger sensing sheet 503 to open, the resistance sensing sheet 502 has less residual water, and the resistance sensing sheet 502 is dehydrated by turning on the heat dissipation motor 707 and the heat dissipation fan 708.

[0048] The heating resistor 504 evaporates the moisture on the resistor sensing sheet 502. The heat of the heating resistor 504 is diffused. The heat of the heating resistor 504 also evaporates the moisture on the trigger sensing sheet 503. The moisture forms water vapor, which is removed by starting the heat dissipation motor 707 and the heat dissipation fan 708. The heat dissipation fan 708 takes in air through the second air vent 7012 and then goes out from the first air vent 7010, forming an airflow in the protective sliding cover 702, and the airflow brings out the water vapor in the protective sliding cover 702.

[0049] The movement of the protective slide cover 702 drives the movement of the trigger rack 802, and the movement of the trigger rack 802 drives the rotation of the trigger gear 804. The rotation of the trigger gear 804 drives the rotation of the transmission rod 803. The rotation of the transmission rod 803 drives the rotation of the bevel gear pair 806. The rotation of the bevel gear pair 806 drives the rotation of the rotating shaft of the gear bracket 805. The rotation of the rotating shaft of the gear bracket 805 drives the rotation of the indirect gear 807. The indirect gear 807 is meshed with the curved tooth plate 808. The indirect gear 807 drives the curved tooth plate 808 to swing. The swing of the curved tooth plate 808 drives the opening and closing of the closed blade 801. The swing of the curved tooth plate 808 drives the displacement of the swing plate 809. The displacement of the swing plate 809 drives the torsion plate 8010 to drive the opening and closing of the closed blade 801. When it rains, the closed blade 801 closes the openings on both sides of the housing 1 to protect the inside of the housing 1.

[0050] The movement of the protective sliding cover 702 indirectly drives the swing plate 809 to move, and the displacement of the swing plate 809 drives the rocker 909 to move upward. The rocker 909 drives the opening and closing cylinder 905 in the magnetic piston 908 to move upward. The displacement height of the magnetic piston 908 exceeds the ventilation slot 907. The induction coil 9010 senses the position of the magnetic piston 908 and starts the two-way air pump 903.

[0051] Start the two-way air pump 903, and extract air from the functional square cylinder 103 through the two-way air pump 903. The outside air enters the functional square cylinder 103 from the ventilation hole 105. The air in the functional square cylinder 103 enters the opening and closing cylinder 905 from the ventilation slot 907, and then flows to the silica gel dehumidification cylinder 901 from the ventilation hole 906 of the opening and closing cylinder 905. The silica gel in the silica gel dehumidification cylinder 901 absorbs moisture from the outside air, and then flows to the bottom of the functional square cylinder 103 after absorbing moisture from the air. Then, the temperature and humidity in the housing 1 are detected by the temperature and humidity sensor 102, and the dehumidification cylinder 901 is started. Heating tube 902 heats the air below the functional square tube 103. The hot air enters the first air pipe 9015 and then flows from the second air pipe 9016 to the outer shell 1. The hot air removes moisture from the inner shell 1 and discharges it through the heat dissipation holes 104, thereby effectively removing moisture and ensuring that the inner shell 1 remains dry. When there is water in the outer shell 1, the water flows through the inclined surface of the inclined bottom plate 9011 to the water collecting box 9012, and the water in the water collecting box 9012 is discharged from the outer shell 1 through the water guide pipe 9013, thereby preventing the water from affecting the distributor in the outer shell 1.

[0052] The silica gel in the silica gel dehumidification cylinder 901 is reused repeatedly; the protective sliding cover 702 slides on the rain sensor box 501; the two-way air pump 903 draws the gas in the outer shell 1 into the silica gel dehumidification cylinder 901 through the second air pipe 9016, and the heat dissipated by the distributor in the outer shell 1 evaporates the moisture in the silica gel in the silica gel dehumidification cylinder 901; when the temperature sensor 9014 detects that the gas in the outer shell 1 is insufficient in heat, the heating tube 902 is started to further heat the gas in the outer shell 1, and the evaporated water vapor in the silica gel enters the upper part of the functional square tube 103 through the opening and closing tube 905, and then the water vapor is discharged from the ventilation hole 105, so that the silica gel in the silica gel dehumidification cylinder 901 can be reused repeatedly.

[0053] When the silica gel in the silica gel dehumidification cylinder 901 evaporates water, a low temperature of 50℃-70℃ is generally used, which does not affect the internal temperature of the outdoor distribution box, ensuring that the silica gel can effectively absorb moisture and evaporate the moisture after heating, while not destroying the structure and moisture absorption capacity of the silica gel, so as to achieve repeated use.

[0054] By protecting the synergistic effect of components such as the sliding cover 702, the heating resistor 504, the cooling fan 708, and the two-way air pump 903, it is ensured that the rain sensing alarm device can respond in time when it rains and effectively protect the electrical components inside the distribution box from the influence of moisture, thereby maintaining a dry environment inside the distribution box, improving the service life and stability of the distribution box, and enhancing the reliability and safety of the system.

[0055] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
