[0034] With the construction and development of the city, in order to facilitate the drainage of the city and the arrangement of the circuit, more underground space is developed and utilized for the construction of the city such as water discharge. In order to facilitate the detection of the underground space, a plurality of inspection wells are provided on the road surface so that the maintenance personnel can enter. However, due to the long time of the underground space in the sealed state and the flow of a large amount of sewage, the inside of the inspection well may accumulate a large amount of toxic and harmful gas, thereby threatening the life of the inspection personnel. How to detect the air condition in the inspection well in real time has become a problem in the process of city construction.

[0035] However, if a detection device is additionally arranged in the well cover or the inspection well, the power supply of the detection device becomes a big problem. Each well cover is in a mutually independent state and is far apart, and cannot be effectively connected by circuit. At the same time, due to the long time in the dark and humid environment, the power supply of the sensor through the internal and external lines of the inspection well will face the risk of damage. Even if the line is connected to the well cover, the power supply line will cause pulling when the well cover is opened, which is not conducive to the opening of the well cover.

[0036] Therefore, the embodiment of the patent provides a photovoltaic detection well cover to solve the above problems.

[0037] First embodiment

[0038] As shown in Figure 1 , Figure 2 and Figure 3 A photovoltaic detection well cover includes a cover body, a detection assembly and a solar panel. The cover body is arranged at the well mouth of the inspection well and covers the well mouth, and the bottom of the cover body is provided with a detection window. The detection assembly is arranged inside the cover body to detect the safety of the inspection well through the detection window, and the solar panel is arranged on the upper surface of the cover body and is electrically connected with the detection assembly to supply power to the detection assembly.

[0039] The cover body of the photovoltaic detection well cover can be installed at the well mouth of the inspection well to seal the inspection well to prevent pedestrians from falling into the inspection well by accident when walking. The detection assembly located in the cover body can detect the gas in the inspection well through the detection window located at the bottom of the cover body. The detection window is arranged to make the detection assembly directly contact with the air in the inspection well, ensuring the accuracy of the detected gas. The detection device analyzes the gas composition in the inspection well in real time and judges whether there is toxic and harmful gas such as methane and hydrogen sulfide in the inspection well or whether the oxygen content in the inspection well meets the standard for the inspection personnel to enter, thereby ensuring the safety of the inspection personnel when entering the inspection well.

[0040] The solar panel on the upper surface of the cover can convert solar energy into electricity after absorbing solar energy, and continuously supply power to the detection assembly to ensure the normal operation of the detection assembly. Further, a storage battery is arranged in the cover, and the storage battery is electrically connected with the solar panel and the detection assembly, for storing the electricity converted by the solar panel and supplying power to the detection assembly. The storage battery can store more electricity, and when the solar panel cannot obtain solar energy at night, the storage battery can continuously supply power to the detection assembly to ensure the normal operation of the detection assembly.

[0041] In addition, referring to Figure 4 The cover is provided with a containing groove, and the solar panel is detachably embedded in the containing groove.

[0042] In order to ensure that the solar panel can absorb more solar energy, the solar panel needs to be arranged above the cover of the well lid. After installation, pedestrians will walk above the well lid, which means that the solar panel needs to have the ability to withstand stepping. When the solar panel is embedded in the containing groove, it can be effectively fixed, and because of the limitation from the containing groove, the solar panel can be prevented from moving when pedestrians walk.

[0043] The depth of the containing groove is the same as the thickness of the solar panel. When the solar panel is placed in the containing groove, its surface will be in the same plane as the upper surface of the cover, which is convenient for pedestrians to walk above the well lid and avoids affecting the walking experience of pedestrians due to the concave or convex of the solar panel.

[0044] In order to maximize the solar absorption efficiency, the solar panel usually adopts cadmium telluride material and is equipped with an anti-reflection coating to reduce light loss. After strict mechanical strength test, the solar panel can ensure that it will not be broken or damaged even under heavy pressure.

[0045] Referring to Figure 1 With Figure 3 The detection assembly includes a detection surface. The detection surface has a display panel, and the containing groove is provided with an inspection window, and the display panel is located in the inspection window.

[0046] The detection table of the detection assembly can detect the air in the inspection well, and the detected value can be presented as a specific gas concentration value through the display panel, so that the maintenance personnel can timely obtain the air condition inside the inspection well. The maintenance window located on the accommodating groove facilitates the installation personnel to install the detection assembly inside the cover body. In order to ensure that the maintenance personnel can accurately read the value on the display panel, the display panel is arranged in the maintenance window, so that the maintenance personnel can conveniently view the information displayed by the display panel through the maintenance window. The embodiment of the patent further specially provides a high-brightness LCD display screen as part of the human-computer interaction interface. When the high-brightness LCD display screen is lighted, the maintenance personnel can read the displayed value through the screen even in the strong light environment of direct sunlight. In addition, since the maintenance window is opened above the accommodating groove, most of the space at the bottom of the accommodating groove can provide support for the solar panel, thereby ensuring the stability of the installation of the solar panel. It is worth noting that the entire device adopts a modular design concept, which means that it is extremely simple and fast to add new functions or replace old components. In particular, when it comes to a solar power supply system, only the upper solar panel needs to be lifted to access all the components below.

[0047] Further, referring to Figure 1 and Figure 3 , the solar panel is provided with an observation port corresponding to the position of the maintenance window, so as to observe the display panel from the outside.

[0048] When installing the photovoltaic detection well cover, in order to ensure that the solar panel can obtain sufficient solar energy, the solar panel will be arranged on the upper surface of the cover body so as to be more completely exposed to the range of sunlight. However, in this case, the solar panel covering the upper surface of the cover body will block the detection table, so that the maintenance personnel cannot read the value on the display panel. Therefore, an observation port is provided on the solar panel. When the solar panel is installed on the cover body, the maintenance personnel can read the gas data on the display panel through the observation port and the maintenance window. A tempered glass panel can be installed in the window frame of the observation window to better form protection.

[0049] In addition, referring to Figure 5 and Figure 6 , the cover body can further include a protection plate. The protection plate is arranged on the detection window and is used to protect the detection assembly accommodated in the detection window.

[0050] Since the detection assembly needs to detect the air inside the inspection well through the detection window located at the bottom of the cover body, the protection plate can provide additional protection for the detection assembly in the cover body.

[0051] Further, the protection plate comprises: an upper layer, a lower layer and a waterproof interlayer. The upper layer is arranged towards the inside of the cover body, and a plurality of first through holes are arranged on the upper layer. The lower layer is arranged towards the outside of the cover body, and a plurality of second through holes are arranged on the lower layer. The waterproof interlayer is arranged between the upper layer and the lower layer, and is used to at least partially isolate the moisture in the gas passing through the second through holes, and the first through holes have a smaller aperture than the second through holes.

[0052] The detection assembly is used to detect the gas composition inside the inspection well, but the inside of the inspection well cannot be directly irradiated by sunlight, and therefore is inevitably in a dark and humid environment for a long time. Regardless of the sensing end of the detection assembly, the main part thereof usually contains electronic elements with high environmental sensitivity, and when being in a dark and humid environment for a long time, there is a risk of shortened service life or damage. Strict waterproof, dustproof and moisture-proof treatment of the electronic elements themselves will undoubtedly increase the cost thereof. Therefore, the waterproof interlayer between the upper layer and the lower layer can isolate the moisture in the gas passing through the first through holes on the lower layer. The gas after removing the moisture contacts the detection assembly through the second through holes.

[0053] Since the gas contacted by the detection assembly is relatively dry, the service life of the assembly can be prolonged. Even if the sensing end is located inside the cover body, the accuracy of the detection result can still be ensured.

[0054] Notably, the first through holes have a smaller aperture than the second through holes, so that the exchange law of the gas at the first through holes is greater than that at the second through holes when the gas passes through the protection plate, which can prolong the time for the gas to stay in the waterproof interlayer and better ensure the waterproof effect.

[0055] Second embodiment

[0056] In the first embodiment of the present application, a photovoltaic inspection well cover is given. The inspection well cover continuously supplies power to the detection assembly through the solar panel, so that the detection assembly located inside the cover body can continuously obtain electric energy. At the same time, in order to protect the detection assembly from being affected by humid gas, a protection plate with a waterproof interlayer is arranged. However, in order to more accurately detect the gas inside the inspection well, a detection assembly with a detection probe capable of extending into the inspection well can be selected.

[0057] Therefore, the second embodiment of the present application improves the first embodiment in that a detection hole is arranged on the protection plate, the detection end of the detection assembly passes through the detection hole and extends into the inspection well, and a sealing element is arranged between the detection end and the detection hole.

[0058] In order to obtain more accurate gas data in the inspection well, the detection end of the detection assembly is inserted through the detection hole on the protection plate, so that the detection end can extend into the interior of the inspection well and directly contact with the gas, thereby obtaining more accurate gas parameters. At the same time, the sealing element between the detection end and the detection hole can effectively block the water vapor in the gas from contacting other components of the detection assembly through the gap between the detection end and the detection hole, thereby effectively preventing the main element of the detection assembly from being damaged due to long-term exposure to a humid environment, protecting the detection assembly and improving the detection sensitivity of the detection assembly for the gas in the inspection well.

[0059] Third embodiment

[0060] In the first and second embodiments of the present application, a photovoltaic detection well cover is provided, which can detect the gas in the inspection well and supply power to the detection assembly in the well cover through a solar panel. Since the solar panel is located on the upper surface of the well cover, pedestrians need to step on the solar panel when walking. The upper surface of the ordinary solar panel is relatively smooth, and the friction between the sole and the solar panel is small when a person walks.

[0061] Therefore, with reference to Figure 1 , Figure 2 and Figure 3 the third embodiment of the present application improves the first and second embodiments. The upper surface of the solar panel is provided with an anti-skid unit, which is protruded or recessed on the upper surface of the solar panel, and the width of the anti-skid unit increases first and then decreases along the length direction of the anti-skid unit.

[0062] When the anti-skid unit is provided on the solar panel, the protruded anti-skid unit on the sheet-shaped body can directly contact with the sole of the pedestrian, and the recessed anti-skid unit can make part of the sole pattern sink and be clamped, thereby increasing the friction between the sole of the pedestrian and the solar panel. It can be understood that the arrangement of multiple anti-skid units increases the roughness of the panel surface and improves the friction coefficient.

[0063] In addition, the special shape design of the anti-skid unit in the present embodiment not only enhances the anti-skid effect, but also cleverly balances the anti-skid performance and light transmittance. The protruded or recessed design provides a three-dimensional structure for the anti-skid unit, further enhancing the anti-skid effect. At the same time, this design can also disperse incident light to a certain extent, reduce glare, and improve the comfort of the observer.

[0064] On the premise of meeting the condition that the anti-skid units are arranged in a shape whose width increases first and then decreases along the length direction of the shape, the anti-skid units can be arranged in various shapes such as crescent, rhombus, ellipse, etc. Such shapes have many advantages, for example, the anti-skid units in the shape of ellipse or rhombus have a larger contact area in the direction perpendicular to the length direction, thus being able to generate a larger friction force in this direction, thereby improving the directional anti-skid effect.

[0065] Meanwhile, at least N anti-skid units are arranged in sequence along a first direction on the upper surface of the solar panel, forming an anti-skid unit group, and at least M anti-skid unit groups are arranged in sequence along a second direction on the upper surface of the solar panel, forming an anti-skid unit array. Wherein, N is a natural number greater than or equal to 2, and M is a natural number greater than or equal to 2; the first direction and the second direction are perpendicular to each other.

[0066] Since the foot of a pedestrian walking on the road surface may not necessarily be exactly in the middle of the solar panel, but may be randomly stepped on any position of the solar panel. The anti-skid units arranged along the first direction and the second direction can cover the surface of the solar panel, providing all-round anti-skid protection. No matter which direction the pedestrian walks from, the pedestrian can contact the appropriate anti-skid structure.

[0067] In actual application, the specific values of N and M can be flexibly adjusted according to the size of the solar panel and the expected use environment. For example, for a larger size panel, larger values of N and M can be selected to ensure that the entire surface is adequately covered with anti-skid units. For a smaller panel, the values of N and M can be appropriately reduced to avoid excessive density of anti-skid units affecting the aesthetics or light transmission.

[0068] In addition, by adjusting the values of N and M, as well as the design of the anti-skid units themselves, customized solutions can be provided for different application scenarios. For example, in public places with heavy pedestrian traffic, the values of N and M can be increased to increase the density of anti-skid units; while in some areas with high landscape requirements, the values of N and M can be appropriately reduced to make the arrangement of anti-skid units more sparse, thereby reducing the impact on the overall visual effect.

[0069] Finally, the upper surface of the cover body can also be provided with lifting holes, which are distributed at the vertices of the upper surface of the cover body.

[0070] When the staff needs to maintain and troubleshoot the inside of the inspection well, sometimes it is necessary to open the inspection well cover and enter the inspection well through the inspection well opening. Therefore, the lifting holes located on the cover body can facilitate the maintenance personnel to insert the lifting hooks into the lifting holes and lift the photovoltaic detection well cover, facilitating the opening of the photovoltaic detection well cover.

[0071] Fourth embodiment

[0072] The fourth embodiment of the present application provides a photovoltaic detection well lid; the fourth embodiment is an improvement of any one of the first to third embodiments, and the improvement is that the detection assembly comprises a detection sensor and a communication module.

[0073] The detection sensor is used for detecting the gas composition in the inspection well.

[0074] Since the inspection wells are distributed relatively dispersedly in the city, the well covers covering the respective well mouths are also relatively dispersed. By relying on the low-power Internet of Things technology, the communication module sends the gas composition in the inspection well obtained by the detection sensor to the terminal, so that the operator can obtain the information obtained by the detection sensor in all well covers in real time through the terminal.

[0075] Since the user does not need to traverse all the inspection wells and observe the values displayed by the respective detection assemblies by naked eyes, the labor cost is significantly reduced, the work efficiency is improved, and the omission or error that may occur during manual checking can be avoided.

[0076] Further, the detection assembly further comprises a control module and an alarm device.

[0077] The control module is in communication connection with the detection sensor, the control module obtains the gas data detected by the detection sensor, and judges whether there is toxic and harmful gas. The alarm device is in communication connection with the control module, and the alarm device responds to the alarm signal of the control module and alarms.

[0078] After obtaining the gas data detected by the detection sensor, the control module can compare the obtained gas data with the internal preset safe gas data, and judge whether the toxic and harmful gas in the inspection well exceeds the standard limit value. The control module can send the calculation result through the communication module, and the user obtains the real-time detection result through the terminal. In addition, the control module is also in communication connection with the alarm device, and when the control module judges that the toxic and harmful gas in the inspection well exceeds the standard according to the detection data, the control module will send an alarm signal to the alarm device, and the alarm device will start and alarm after obtaining the alarm signal. Through the work of the alarm device, the staff can be reminded, the timely maintenance is facilitated, and the personnel near the inspection well can also be warned to avoid or emergency disposal.

[0079] The above-described specific embodiments further specifically describe the purpose, technical solutions and advantages of the present application, and it should be understood that the above-described specific embodiments are only specific embodiments of the present application and are not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
