Technical Field

[0001] The present invention belongs to the technical field of smart water services, and in particular relates to a moisture-proof box for rainwater and sewage inspection well monitoring equipment. Background Art

[0002] Drainage pipe networks are important facilities for conveying sewage and discharging rainwater. They maintain urban environmental sanitation and public health, including effectively preventing urban waterlogging, protecting urban water environment and water quality, improving the overall environmental quality of cities, and promoting sustainable urban development. Therefore, the normal operation of urban drainage pipe networks plays a vital role in the healthy development of cities. In the development of urban drainage pipe networks, due to their deep underground burial and complex on-site working conditions, such as pipe network damage, mixed and wrong connection of rainwater and sewage pipe networks, the normal and healthy operation of drainage pipe networks is seriously affected, increasing the risks of urban waterlogging and combined system overflow pollution, and various types of water quality and hydrodynamic monitoring equipment are needed to assist in perception. However, since the urban drainage pipe network belongs to a severely humid environment, the equipment is placed inside the pipe network for a long time for measurement, and moisture is easy to invade the inside of the equipment. In addition, the rainwater and sewage pipes are affected by the mixing of external water, and there is a sudden temperature drop. High humidity and sudden temperature drop can easily cause circuit condensation, causing equipment short circuit, resulting in abnormal operation or even damage of the equipment. It has become the main cause of equipment loss in the field of water monitoring, causing a large amount of economic losses.

[0003] Therefore, how to provide a moisture-proof structure for a rainwater and sewage inspection well monitoring device to prevent moisture inside the monitoring equipment under conditions of large-scale water level fluctuations has become a technical problem that technical personnel in this field urgently need to solve.

The moisture-proof structure helps to keep the internal environment of the equipment dry, which helps to maintain the accuracy of the monitoring equipment and ensure that the various types of monitoring data obtained are accurate. Due to the effectiveness of the moisture-proof structure, the number of equipment failures and maintenance caused by humid environments is reduced, thereby reducing long-term maintenance costs.

[0029] The present invention has high water vapor absorption and condensation efficiency.

[0041] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0042] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0043] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0044] like Figure 1 to Figure 2 As shown, in one embodiment, the moisture-proof box for rainwater and sewage inspection well monitoring equipment of the present invention, the structure is suspended in the sewage pipe in the inspection well, and includes:

[0045] The box body 11 is a hollow structure and is arranged on the rainwater and sewage inspection well anti-fall net hook 21. Through the vertical freedom around the hook, through its own buoyancy and the buoyancy of the floating ring 14, it is used to prevent sewage immersion, reduce the infiltration of external water pressure and provide a certain buoyancy;

[0046] A hanging component 12, which is arranged on the outside of the box body 11, and is used to semi-fix the box body 11 in the inspection well to prevent it from being washed away by water flow, while retaining the vertical freedom to swing around the hook;

[0047] A condensation needle 13, which is disposed inside the box body 11 and is used to process condensed water vapor in the box body 11 and reduce the water vapor pressure;

[0048] The floating ring 14 is a porous structure and is arranged at the bottom of the box body 11 to provide additional buoyancy and display the historical record of the sewage immersion water level.

[0049] The box body is a hollow structure and is set in the rainwater and sewage inspection well to prevent sewage from entering. Specifically:

[0050] The box body includes a top cover, sides and bottom, and is in the shape of a cuboid. The size can be customized according to needs to adapt to the space in the rainwater and sewage inspection well. The box body is a hollow structure with sufficient internal space to accommodate monitoring equipment and related components. The box body is used to prevent sewage immersion and reduce external water pressure from penetrating into the box body through the vertical freedom around the hook, as well as its own buoyancy and the floating ring. Its surface is coated with an anti-rust coating to increase its durability in harsh environments. The box body is designed with a waterproof sealing strip to ensure that the interior can remain dry even in sewage environments.

[0051] The floating ring is designed with a porous structure, which enables it to float on the water surface while having a certain mechanical stability. The porous structure of the floating ring will be filled with impurities in rainwater and sewage, and the color change of the floating ring allows the maximum historical immersion to be observed through the holes. This design allows the monitoring personnel to visually see the flooding state of the box, which is convenient for the operation and maintenance personnel to make a preliminary judgment on the state of the box. The porous structure also helps to reduce the use of materials, thereby reducing the overall weight and ensuring the buoyancy of the floating ring. The material is corrosion-resistant, lightweight and well-buoyant materials, such as high-density polyethylene (HDPE) or polypropylene (PP), which can not only resist chemicals that may be contained in sewage, but also ensure stability and durability in long-term use. The floating ring is set at the bottom of the box because the water level change inside the box usually starts from the bottom. By setting the floating ring at the bottom, it can be ensured that the immersion change can be recorded in time. The role of the floating ring is to achieve passive recording of the immersion state of the box through the deposition of impurities in the submerged water in the pores.

[0052] like Figure 2 As shown, Figure 2 The specific installation environment of the present invention is shown. Usually, a protective net is installed at the inspection well mouth, and the protective net is set by a hook 21 at the inspection well wall. In order to prevent the box body from being deeply submerged and under pressure, resulting in water entering the box body, the hook is designed to be able to be unhooked upwards. Since the hook is designed to be able to be unhooked upwards, this means that in the case of ultra-high water levels, the hook will be detached from the well wall due to buoyancy. In order to avoid this situation causing the equipment to be suspended and possibly lost, or to prevent the moisture-proof box from being flooded too deeply and causing water to enter, additional safety measures need to be taken. The role of tightening the rope is to serve as a backup safety measure to prevent adverse consequences caused by accidental unhooking of the hook.

[0053] The fastening rope can be fixed to a fixed point on the well wall and connected to the equipment hook. If the hook is accidentally unhooked, the fastening rope can prevent the equipment from being completely suspended or lost, and keep the equipment in a fixed position in the well. The moisture-proof structure for the rainwater and sewage inspection well monitoring equipment is suspended in the sewage pipe in the inspection well. At the same time, the box body needs to be suspended on the protective net through a connector and the hanging part of the box body to resist the vibration and impact that may be caused by the flow of sewage, ensuring the stability of the equipment and the durability of long-term operation.

[0054] The hanging component 12 is arranged on the outside of the box body 11, and the hanging component 12 is used to fix the box body 11 in the inspection well.

[0055] Specifically, Figure 3a-3c As shown, the hanging component 12 includes a well wall hook bracket 31 and an anti-tilt bracket 32; the well wall hook bracket 31 is a triangular structure, used to attach the box body 11 to the wall of the inspection well; the anti-tilt bracket 32 ​​is a trapezoidal structure, including an anti-excessive downward tilt bracket 321 and an anti-excessive upward tilt bracket 322; wherein, the anti-downward tilt bracket 321 is arranged at the bottom of the well wall hook bracket 31, for preventing the box body 11 from tilting excessively downward; the anti-upward tilt bracket 322 is arranged at the top of the well wall hook bracket 31, for preventing the box body from tilting excessively upward.

[0056] A through hole 33 is provided at the connection between the well wall hook bracket 31 and the anti-tilt bracket 32 ​​, and the box body 11 is fixed by passing a connecting piece through the circular hole 33 .

[0057] Well wall hook bracket: It has a hollow triangular structure, and its design enables it to be firmly attached to the well wall of the inspection well. The triangular structure is often used for support and fixation due to its stability. In the absence of water, the bracket 321 to prevent excessive downward tilting can prevent the box body 11 from tilting excessively downward. When the water level rises to the box body 11, the floating ring 14 provides a better floating support angle under the support of the bracket 321 to prevent excessive downward tilting. Furthermore, when the water level continues to rise, the bracket 322 to prevent excessive upward tilting also prevents the box body 11 from tilting excessively upward, reduces the friction between the through hole 33 and the hook part, and helps the box body 11 to be unhooked upward when it is not completely submerged, so as to avoid the box body from being deeply submerged and under pressure, resulting in water entering the box body.

[0058] Anti-tilt bracket: It has a trapezoidal structure, which can withstand forces from different directions and keep the box balanced. It includes two parts, namely, the anti-downward excessive tilt bracket and the anti-upward excessive tilt bracket. These two parts work together to ensure that the box remains horizontal in the vertical direction and will not tilt due to external forces. The anti-downward tilt bracket is located at the top of the well wall hook bracket. Its function is to prevent the box from tilting downward due to gravity or external impact. This can protect the monitoring equipment in the box from damage and keep it working normally. Anti-upward tilt bracket: It is located at the bottom of the well wall hook bracket and is used to prevent the box from tilting upward due to external forces (such as water flow impact). This ensures the stability of the box and avoids unnecessary influence on the monitoring equipment. There are through holes at the connection between the well wall hook bracket and the anti-tilt bracket. By passing the connector through these round holes, the box can be fixed in the inspection well. This fixing method is not only structurally stable, but also easy to maintain and replace. In harsh environments such as sewage pipes, equipment needs to withstand various external forces, such as water flow impact, temperature changes, etc. In summary, the design of the anti-tilt bracket ensures the stability of the device in the vertical direction, preventing damage to the device or liquid leakage due to excessive tilting. By preventing damage to the device due to tilting, the anti-tilt bracket helps improve the durability of the device and ensure long-term stable operation.

[0059] In summary, the suspension components of the present invention constitute a semi-stable suspension system, and the design of the suspension components and connectors of the box body takes into account the vibrations that may be caused by the water flow. It is also possible to further absorb and reduce the impact of the water flow on the box body by using shock-absorbing materials and buffer devices to keep the box body stable. A floating balance system can also be further optimized between the float ring and the box body, so that the box body can automatically adjust its position when the water flow changes and maintain stability without affecting the accurate monitoring of the water level. In extreme cases, such as a sharp rise in the water level in the well, the float ring can provide sufficient buoyancy, and placing an inclined bracket can assist in complete unhooking, ensuring that the box body will not sink into the water and protecting the monitoring equipment from damage.

[0060] like Figure 4a-4d As shown, the condensation needle 13 is arranged inside the box body 11 through a fixed support 34 at the bottom of the box body 11, and includes a tank body 41, a thermal management module 42, and a cooling and drainage module 43;

[0061] The tank 41 is used to contain water droplets condensed into liquid;

[0062] The thermal management module 42 is connected to the cooling and drainage module 43 , and provides a cold source for the cooling and drainage module 43 through the principle of semiconductor refrigeration, and dissipates heat to the outside of the box body 11 .

[0063] The cooling and drainage module 43 is aligned with the center of the tank body 41 , and is used to absorb water vapor entering the box body 11 and condense it into liquid, and guide the liquid into the tank body 41 .

[0064] Furthermore, an anti-evaporation nozzle 411 is provided on the top of the tank body 41. The anti-evaporation nozzle 411 is a convergent mouth structure, which is used to reduce the secondary evaporation of water in the tank body and prevent liquid from overflowing through capillary phenomenon when the tank body is tilted; calcium chloride water-absorbing crystals 412 are provided at the bottom of the tank body 41 to absorb the liquid entering the tank body 41.

[0065] The tank is used to collect and contain liquid condensed from water vapor. The anti-evaporation nozzle is set at the top of the tank and has a convergent mouth structure to prevent the liquid in the tank from overflowing. This design ensures that when the amount of liquid in the tank increases, the liquid will not overflow from the tank, keeping the inside of the equipment clean. The calcium chloride water-absorbing crystals are located at the bottom of the tank to absorb the liquid entering the tank. Calcium chloride has strong hygroscopicity and can effectively absorb moisture in the tank to keep the environment inside the tank dry.

[0066] Further, the thermal management module 42 includes a hot end 421, a cold end 422, a thermal grease 423, and a cold end insulation tank 424;

[0067] The thermal conductive silicone grease 423 is disposed on the lower surface of the top cover of the box body 11, and is used to connect the condensation needle 13 and the box body 11 and assist in heat dissipation;

[0068] The hot end 421 is arranged at the bottom of the thermal conductive silicone grease 423, and the thermal conductive silicone grease 423 is in close contact with the box body 11. The hot end 421 and the cold end 422 together form a semiconductor cooling plate, which is driven by electricity. The thermal conductive silicone grease 423 of the hot end 421 conducts the internal heat out of the box body, and the temperature of the cold end 422 drops, providing coldness for the cooling and drainage module 43;

[0069] The cold end 422 is disposed at the bottom of the hot end 421 to provide coldness to promote condensation of water vapor into liquid;

[0070] The cold end insulation groove 424 is disposed around the bottom of the cold end 422 to maintain the temperature of the cold end 422 and prevent condensation of water vapor.

[0071] Since the inside of the detection equipment needs to be kept dry to protect sensitive electronic components and ensure the normal operation of the equipment. By promoting condensation of water vapor, the moisture in the air can be converted into liquid water, thereby removing moisture from the inside of the equipment. For rainwater and sewage inspection well monitoring equipment, condensed water vapor helps to maintain the stability of the internal environment of the equipment, thereby improving the accuracy of monitoring data. Since there is always a certain amount of water vapor in the air, the cold end insulation tank maintains a low temperature inside, while the external ambient temperature is usually high, so the outer surface temperature of the insulation tank will be lower than the temperature of the surrounding air. When warm and humid air contacts the cold outer surface of the insulation tank, the temperature of the air will decrease. If the surface temperature is lower than the dew point temperature of the air (the temperature at which water vapor in the air begins to condense into liquid water), the water vapor will condense into water droplets. If water vapor condenses into dew on the external surface of the equipment, it may cause corrosion of metal parts and affect the service life and appearance of the equipment. If condensation occurs on the external surface of the cold end, moisture may penetrate into the insulation material, reducing its insulation performance and increasing energy consumption. Condensation may provide conditions for the growth of bacteria and mold, which may pollute the internal environment of the equipment. Preventing condensation helps keep the outside of the equipment dry, which is very necessary for the long-term stable operation and maintenance of the equipment.

[0072] Based on this, the thermal management module of the present invention is used to control and adjust the heat of a device or system to ensure that the device operates within a suitable temperature range, specifically:

[0073] Thermal grease is provided on the lower surface of the top cover of the box body, and is used to connect the condensation needle and the box body and assist in heat dissipation. The thermal grease plays a dual role here: first, it acts as a heat-conducting medium to help better transfer heat between the condensation needle and the top cover; second, it acts as a tape to fix the needle on the top cover to achieve auxiliary heat dissipation.

[0074] The hot end is located at the bottom of the thermal grease and is slightly larger than the thermal grease. The hot end is the main part that generates heat, and its area is slightly larger to ensure that the heat can be evenly transferred to the thermal grease and then conducted to the top cover.

[0075] The cold end is located at the bottom of the hot end, with a slightly smaller area than the hot end, and is surrounded by the cold end insulation groove. The cold end is the end point of heat transfer, and its slightly smaller area helps to concentrate the cold and improve the heat conduction efficiency.

[0076] The cold end insulation tank is located at the bottom of the cold end and surrounds the cold end. The design of the cold end insulation tank helps maintain the temperature of the condensed water, prevents heat from entering from the outside, and ensures that the condensed water will not re-evaporate due to the increase in temperature during the processing process, thereby ensuring condensation efficiency. With good insulation performance, it can significantly reduce the heat exchange between the condensed water and the environment, and reduce the energy consumption of the system. On the outer surface of the cold end insulation tank, due to the high external ambient temperature, condensation may form on the surface of the insulation tank. The design of the insulation tank can reduce condensation, keep the equipment dry, and avoid corrosion problems caused by condensation. At the same time, the insulation tank can also protect the cold end and prevent the intrusion of external impurities and dust.

[0077] The hot end and the cold end together form a semiconductor refrigeration plate, which can be driven by electricity to transfer heat from one end to the other end; for example, if the internal heat is transferred to the hot end on the outside, the hot end will export the internal heat out of the box, and the temperature of the cold end will drop, providing cooling for the cooling and drainage module; by reversing the direction of the current, the external heat can also be transferred to the cold end on the inside, heating the hydrated calcium chloride crystals to lose their bound water, which can be regenerated to provide a water absorption medium for the next operation.

[0078] In summary, the thermal management module connects the condensation needle and the box body through thermal grease to achieve effective heat transfer. This helps to maintain the temperature balance of the entire structure. The cold end insulation groove surrounds the bottom of the cold end. Its main function is to maintain the temperature of the cold end, prevent external heat from entering, and avoid condensation of water vapor on the surface of the cold end. This helps to keep the internal environment of the equipment dry and prevent corrosion and pollution problems caused by condensation. The thermal management module plays a vital role in the entire structure. It ensures the normal operation and effective moisture-proofing of the rainwater and sewage inspection well monitoring equipment by precisely controlling and transferring heat, thereby improving the reliability of the equipment and the stability of long-term operation.

[0079] In one embodiment, inside the rainwater and sewage inspection well monitoring equipment, water vapor is generated due to the contact between water vapor in the air and the condensation needle. These water vapors may come from the moisture in the sewage pipe, or be generated by the inside of the equipment. The area of ​​the hot end is slightly larger than the thermal grease to ensure that the heat can be evenly transferred and dissipated outward. The area of ​​the cold end is slightly smaller than the hot end, which helps to concentrate the cold amount and improve the efficiency of heat conduction. At the same time, the low temperature of the cold end provides cold capacity to improve the efficiency of condensing water vapor into liquid in the cooling and drainage module 43. The cold end insulation tank surrounds the bottom of the cold end, which helps to maintain the condensation temperature and prevent heat from entering from the outside. The design of the cold end insulation tank helps to reduce condensation, keep the equipment dry, and avoid corrosion problems caused by condensation. At the same time, the insulation tank can also protect the cold end to prevent the intrusion of external impurities and dust.

[0080] Further, such as Figure 4c-4dAs shown, the cooling and drainage module 43 includes a preset number of condensing fins 431, cooling and drainage needles 432, and condensed water diversion grooves 433;

[0081] The condensation fins 431 are respectively arranged on the cold drainage needles 432, and are used to absorb the water vapor entering the box body 11 and condense it into liquid; the bottom of the condensation fins 431 near the cold drainage needles 432 is provided with slots, which facilitate the fine water droplets on the condensation fins 431 to quickly enter the slots through capillary phenomena. The slots are aligned with the guide gaps of the cold drainage needles 432 and are connected as a whole. Condensed water can be quickly guided to the lower end of the cold drainage needles 432 through the slits.

[0082] The cooling guide needle 432 passes through the cold end insulation groove 424 and the anti-evaporation nozzle 411 and is located on the same axis. The cooling guide needle 432 is composed of two semi-cylinders with a guide gap of no more than 0.5 mm, and the middle gap plays a drainage role. The lower end of the cooling guide needle 432 is a semi-conical structure, which is conducive to the formation of condensed water droplets. It is used to guide the water vapor condensed into liquid into the tank body 41 through the condensed water guide groove 433.

[0083] Specifically, the condensing fins are installed on the cooling drainage needles. This design helps to increase the surface area, thereby improving the absorption and condensation efficiency of water vapor. The fins are made of materials with good thermal conductivity to promote heat transfer. The cooling drainage needle passes through the cold end insulation groove and the anti-evaporation nozzle, and guides the water vapor condensed into liquid into the tank body through the condensation water diversion groove. The gap between the cooling drainage needle and the anti-evaporation nozzle is less than 1.5mm. The anti-evaporation nozzle is a convergent mouth structure. The reduced orifice and the needle cooperate with each other. Relying on the surface tension of water, it can reduce the secondary evaporation of water in the tank body to a certain extent, and prevent tilting and overflowing through capillary phenomenon when the tank body is tilted. The condensation water diversion groove is designed to guide the condensed liquid to flow to the tank body. So that the liquid will not be lost or overflow during the diversion process.

[0084] In one embodiment, a cooling and drainage module of the present invention is installed inside the box of the rainwater and sewage inspection well monitoring device. The module includes a preset number of condensing fins, cooling and drainage needles, and condensed water diversion grooves. When water vapor enters the box, it is absorbed by the condensing fins and condensed into liquid. The liquid is guided by the cooling and drainage needles, passes through the cold end insulation groove and the anti-evaporation nozzle, enters the condensed water diversion groove, and finally flows into the tank.

[0085] In summary, in the process of water vapor absorption and condensation, the design and installation method of the condensing fins increase the surface area in contact with water vapor, and improve the absorption and condensation efficiency of water vapor on the condensing fins. The close fit between the cold drainage needle and the anti-evaporation nozzle prevents the tilting overflow of the liquid and ensures that the liquid after the condensation of water vapor can be effectively guided into the tank. The design of the cold end insulation tank helps to maintain the low temperature of the cold end, thereby improving the efficiency of water vapor condensation, while preventing water vapor from condensing on the cold end surface, ensuring the dry environment of the equipment. For system efficiency and reliability, the design of the cold drainage module takes into account the efficiency and reliability of water vapor treatment, and improves the processing capacity of the overall system by optimizing the number and size of fins and the layout of the cold drainage needles. Therefore, the cold drainage module of the present invention has the function of water vapor absorption and condensation. Through these components and designs, the cold drainage module plays a vital role in the moisture-proof structure of the entire rainwater and sewage inspection well monitoring equipment. It ensures that the equipment can effectively handle water vapor and maintain a dry and clean environment, thereby improving the reliability of the equipment and the stability of long-term operation.

[0086] In one embodiment, the specific use steps of the moisture-proof box for rainwater and sewage inspection well monitoring equipment of the present invention are as follows:

[0087] S1. When the moisture-proof structure is used for the first time, about 1 / 5 volume of calcium chloride crystals are introduced into the bottom of the tank 41;

[0088] S2. When the moisture-proof structure is used again, cover the box body 11 and introduce reverse current to the thermal management module 42. At this time, the functions of the hot end 421 and the cold end 422 are reversed. The hot end 421 cools and conducts the cold to the outside of the box body 11 through the thermal grease 423. The cold end 422 heats and heats the box body 11 through the cold conduction and drainage module 43 to keep the temperature of the box body 11 higher than 35°C. The process lasts for 1 hour to reduce the bound water content of the calcium chloride crystals.

[0089] S3. When the internal temperature drops to room temperature, lock the box body 11 and install the box body 11 on the protective net hook 21. Under normal circumstances, the thermal management module 42 inside the box body 11 is not in operation. Only when the temperature drops by more than 2°C compared with the highest temperature in the past 7 days or the humidity of the box body 11 is greater than 70%, the thermal management module 42 introduces a forward current, the hot end 421 generates heat, and conducts heat to the outside of the box body 11 through the thermal grease 423. The cold end 422 cools and collects condensed liquid through the cold conduction and drainage module 43.

[0090] S4: When the maximum temperature drops by less than 2°C or the humidity of the box body 11 is less than 70%, the thermal management module 42 stops working. Figure 5 As shown, the thermal management module worked from minute 1175 to minute 1198 of the year, and the overall event working time was 23 minutes.
