The present invention relates to a watch-type waterproof manhole buried underground, and more particularly, to provide a manhole structure that blocks the inflow of inflow into the manhole while leaking occurs when the external inflow into the manhole early The present invention relates to a supervised waterproof manhole that detects and leaks information wirelessly to prevent the inundation of expensive equipment installed inside the manhole and to maintain the best state inside the manhole.

Many types of coffins are intricately buried in urban roads. These pipes are continually being expanded, and underground spaces are installed everywhere to manage and control the pipes. In recent years, the need for more complex spaces for managing various electrical and electronic communication facilities required for industrial infrastructure construction is also increasing.

In the case of water supply and sewage pipelines, they are not buried underground only by connecting continuous pipes, but by installing additional facilities such as water valve, air valve, pressure reducing valve, safety valve, Ito pipe, hydrant, etc. It makes it easy to crack down and make things easier. These facilities need to be put together in one place for easy management and inspection, and according to their needs, a lid is placed on the ground and a space for people to enter the ground is the manhole. .

The water-removal valve installed inside the manhole body is used for the purpose of singularity in case of need for auxiliary and pipeline change work such as pipe rupture, leakage, construction, drainage of drainage pipe, branch of water supply pipe, etc. Also adjust the water pressure to make sure.

Because of this necessity, manholes are installed underground to install valves and operate the valves. Manhole construction in the ground is a variety of construction methods such as masonry construction method, but there is a problem in the perfect waterproof inside the manhole. In particular, there is an even greater problem in the manhole structure for systematic and integrated management of various electrical and electronic communication facilities installed in the manhole in order to construct various industrial infrastructures.

Therefore, when a leak occurs and external inflow water flows into the manhole, it detects it early and informs the leak information wirelessly to prevent intrusion of expensive equipment inside the manhole and to maintain the best state inside the manhole. Development of waterproof manhole technology is urgently needed.

The technical problem to be solved by the present invention is to install an antenna installation hole separately from the manhole hole to effectively prevent the inflow of external inflow into the manhole and to buried antenna that can stably transmit and receive radio waves buried underground It is to provide a surveillance waterproof manhole provided.

Monitoring type waterproof manhole according to the present invention for achieving the above technical problem, the manhole body buried underground and having a constant internal space; A manhole hole formed through one side of an upper surface of the manhole body; A manhole hole extension part extending upward from the manhole hole; A manhole cover covering and sealing the upper surface of the manhole hole extension and installed at the same height as the ground; An antenna installation hole formed through the upper surface of the manhole body on the other side where the manhole hole is formed; An antenna mounting extension extending upward from the antenna mounting; A sensing device for sensing a state inside the manhole body along a wall surface or a space inside the manhole body; A processing device for obtaining and storing information detected by the sensing device; It is installed on the antenna installation extension portion, the embedded antenna for transmitting and receiving information transmitted from the processing device with the outside; includes.

In the present invention, the buried antenna, the antenna installation member is installed on the upper surface of the antenna installation extension portion at the same height as the ground; It is preferably included in the antenna installation member, the antenna for transmitting and receiving to the outside.

Particularly, the antenna mounting member may include a frame providing a space in which the antenna may be installed in the center, and a protective sealing member filled in the frame. The antenna mounting member may waterproof the antenna and the manhole. It is more preferable because it can withstand the pressure at the top.

In the present invention, the antenna is a front directional antenna that radiates radio waves in a specific plane direction, and the plane directional antenna is installed to be inclined so as to have a constant inclination with the ground in the frame, so that it stably radiates radio waves. It is preferable because it can receive.

According to the present invention, since an antenna installation hole for installing a buried antenna is provided separately from a manhole hole through which an operator enters and exits, the inside of the manhole can be more reliably waterproofed and the antenna can be protected.

In addition, the buried antenna provided in the watch-type waterproof manhole of the present invention has a structure that can sufficiently withstand the pressure applied from the top, there is an advantage that can be stably transmit and receive radio waves even when buried underground.

Hereinafter, with reference to the accompanying drawings will be described in detail a specific embodiment of the present invention.

As shown in FIG. 1, the supervised waterproof manhole according to the present embodiment includes a manhole body 10, a manhole hole 12, a manhole hole extension 14, a manhole cover 20, and an antenna installation hole 30. ), The antenna installation extension portion 32, the sensing device 60, the processing device 40 and the embedded antenna 50 is configured.

First, the manhole body 10 refers to a structure buried underground for installation of a pipe or an electric and electronic communication facility. The manhole body 10 may be made of a material such as concrete or FRP, and a certain sealed space is formed therein, and pipes are installed. The manhole body 10 may have various shapes such as a rectangular parallelepiped or a cylinder.

As shown in FIG. 1, the manhole hole 12, which is a passage through which an operator can enter and exit the manhole main body 10, is formed on the upper side of the manhole body 10. The manhole hole 12 is preferably formed to a minimum size that a worker can pass through, and the manhole hole 12 is further provided with a ladder (not shown in the drawing) or the like to facilitate movement of the worker. It may be installed.

The manhole hole 12 extends upward and opens to the ground surface. For this purpose, the manhole hole extension 14 extends to the ground surface. The upper opening of the manhole hole extension 14 is sealed by the manhole cover 20. In this case, the sealing member 22 may be further provided at the portion where the manhole hole extension 14 and the manhole cover 20 are in contact with each other in order to waterproof the inner space of the manhole body 10. Of course, if the waterproof function can be reliably made without the sealing member 22, the sealing member may not be installed.

The manhole cover 20 is detachably installed from the manhole hole extension 14. For example, lifting the manhole cover 20 from the upper side may have a structure that opens upward. In addition, since the manhole cover 20 is installed to be exposed to the ground surface, a vehicle or the like may pass over the manhole cover 20. Therefore, the manhole cover 20 should be made of a material which is not damaged even by such external pressure or impact, and the manhole hole extension 14 also has a load of the manhole cover 20 and an external load applied from the upper side of the manhole cover 20. It can be made of a material that can support all, for example, a concrete structure or a steel tube structure.

Next, as shown in FIG. 1, the antenna installation tool 30 is formed through the upper surface of the manhole body 10 on the other side where the manhole hole 12 is formed. This antenna installation port 30 is a structure that is formed only in the supervised waterproof manhole according to the present embodiment, unlike the general manhole in order to install the embedded antenna 50 to be described later. Installing the buried antenna 50 in the manhole hole 12 not only interferes with the entry and exit of the operator, but also may cause management problems, so that the antenna installation port 30 is separately formed. Since the antenna installation port 30 does not need to be passed by the operator, it may be formed in a size smaller than that of the manhole hole 12, and it is sufficient to have a size enough to install the antenna upward from the inside of the manhole body 10. Do.

Similar to the manhole hole 12, the antenna mounting tool extension portion 32 extends in this antenna mounting tool 30 in the upward direction. A buried antenna 50 is embedded in the upper surface of the antenna fitting extension portion 32. The upper surface of the embedded antenna 50 and the upper surface of the antenna installation extension portion 32 is completely in contact with each other so that water or air cannot pass through. The antenna fitting extension portion 32 is also a hard material sufficient to support the load by the buried antenna 50 and the external force that presses the buried antenna 50 from the top, for example, concrete or cast iron pipe It is preferable that it is made of.

And the upper portion of the antenna installation extension portion 32, as shown in Figures 1 and 2, the buried antenna 50 is installed. The embedded antenna 50 is a component that transmits and receives information transmitted from the processing device 40 to the outside in a state buried underground. To this end, in the present embodiment, the embedded antenna 50 includes an antenna mounting member and an antenna 56, as shown in FIG.

First, the antenna mounting member is a component that is installed at the same height as the ground on the antenna installation extension portion 32, serves to provide a space for installing the antenna 56 and to secure the installed antenna. In addition, the antenna is waterproof to prevent water from entering the installed antenna.

Specifically, the antenna installation member is composed of a frame 52 and a protective sealing member 54. Frame 52 is a component that has a strong strength to withstand the pressure applied from the upper side and protects the antenna 56, for example, may be made of a material such as cast iron. In this embodiment, as shown in Fig. 2, the frame 52 penetrates through the center portion in the vertical direction, and through-holes are formed. The separation of the protective sealing member 54 to be described later is prevented without disturbing transmission and reception.

The protective sealing member 54 is filled in the through hole of the frame 52 and fills all other spaces inside the through hole as if the antenna 56 is installed to surround the antenna. To this end, the protective sealing member 54 is preferably formed by pressurizing and filling the frame 52 in a resin state with fluidity. When the resin is filled in the through hole of the frame 52 in the state of fluidity, it is caught by a plurality of comb-shaped protrusions formed in the through hole and is not separated from the frame. In this way, since the curing is completely in close contact with the frame 52, the protective sealing member 54 is not separated or separated from the frame 52.

The protective sealing member 54 may be made of various resins having properties of being filled in such a flowable state and cured after being filled, for example, may be made of an epoxy resin. In particular, the epoxy is preferably a colored epoxy because it improves the appearance.

Next, the antenna 56 is installed in the through hole of the frame 52 while being supported by the antenna support member 58. The antenna support member 58 has a structure that can be detached from the lower side of the frame 52. The antenna support member 58 is preferably detachably coupled to the frame 52 by bolts 51 or the like so that the antenna 56 can be separated or maintained from the lower side when maintenance of the antenna 56 is required.

In this embodiment, the antenna support member 58 preferably supports the antenna 56 at an angle as shown in FIG. 2. The antenna 56 is preferably composed of a front directional antenna that radiates radio waves in a specific plane direction. However, when the antenna 56 is directed upward, the emitted radio waves are inefficiently transmitted. Therefore, the antenna 56 is installed at an angle so that the radio wave is diverted to the correct radio wave receiver. In addition, an antenna cover may be further provided on the antenna 56.

Next, the sensing device 60 is a component that is installed along a wall surface or a space inside the manhole body 10 to detect an internal state of the manhole body 10. Specifically, as shown in FIG. 1, the detection device 60 includes a bottom surface leak detection unit 61, a middle layer leak detection unit 62, a manhole internal state detection unit 63, and a lid opening / closing detection unit 64. And it may be configured to include a control board (65). The bottom leak detector 61 and the middle floor leak detector 62 may be configured as a leak detection sensor that detects a leak of the middle floor where the manhole main body 10 and the inner bottom surface are installed. The internal state detecting unit 63 is mounted on the wall surface of the manhole main body 10 to check and detect temperature and humidity, gas, and vibration in the manhole. The lid opening and closing detection unit 64 is installed in the manhole hole 12 to detect whether the manhole cover 20 is open or closed. Finally, the control board 65 is connected to the sensing units 61, 62, 63, and 64 by wires to transmit and receive and control electrical signals.

Next, the processing device 40 is a component that acquires and stores the information detected through the sensing device 60. The processing device 40 transmits the obtained information to the antenna 56 and sends it to the outside. And it is preferable to store the obtained information because the storage means (not shown in the figure) itself is provided.

On the other hand, it is preferable that the solar power generation unit 90 is further provided in the watch type waterproof manhole according to the present embodiment. To this end, as shown in FIG. 1, the solar cell installation unit 90 is detachably installed adjacent to the embedded antenna 50. The solar cell installation unit 90 may be configured to include a solar cell installation box 96, the cell 92 and the solar cell protective device 94.

First, as shown in FIG. 3, the solar cell installation box 96 is provided with an upper surface open to be adjacent to the frame 52 of the buried antenna, and is a component made of a hard metal material. The solar cell installation box 96 may have various shapes such as a hexahedron. The solar cell installation box 96 has a constant internal space, the solar cell module 92 is installed in the space, the upper surface is open and covered with the solar cell protective device 94.

Next, the solar cell 92 is installed at the same height or higher than the upper surface of the solar cell installation 96 inside the solar cell installation 96, and performs solar power generation to the embedded antenna 50. It is a component that supplies power to the sensing device and processing device 40. The solar cell 92 generally requires a commercially available solar cell module, and various solar cell modules may be used as necessary.

Next, the solar cell protector 94 is made of a transparent material, and is a component installed to surround the solar cell 92 on the solar cell installation box 96. Since the solar cell protective device 94 must protect the solar cell from external pollution or external force and transmit solar light without loss, it is preferable that the solar cell protective device 94 is made of a transparent material having excellent strength. For example, it may be made of a transparent plastic material such as tempered glass or PMMA.

In this embodiment, the solar cell protective device 94 is configured to completely cover the upper surface of the solar cell mounting box 34, as shown in Figure 3, the shape is made of a parabolic (parabolic) shape of the solar It is preferable to make it advantageous for condensing.

In addition, in the present embodiment, the light of the wavelength suitable for photovoltaic power generation of the solar cell 92 passes through the surface of the solar cell protective device 94, and the light of the remaining wavelength is further formed to form a beam splitting coating. desirable. Beamsplit coatings are coatings that allow light of a particular wavelength to pass and reflect light of another wavelength.

Specifically, the spectral characteristics of sunlight in a specific wavelength region of the beam splitting coating are a pair of a thin film made of one of HfO, ZrO ₂ , TiO ₂ and TaO ₂ and a protective coating film made of SiO ₂ . This is achieved by a method of laminating as a specific number of times. When coating the beam splitter for forming a reflective film for a hot mirror or a cold mirror, the material is formed of any one of Hfo, ZrO ₂ , TiO ₂ and TaO ₂ . It is common to make a reflective surface by coating a thin film 1/4 times the wavelength of the wavelength to be reflected. When a protective coating film made of transparent SiO ₂ is coated on it, the coating is protected and the sun according to a specific wavelength range is applied. The light may be selectively separated according to the wavelength range by the thickness of the protective coating layer or the number of laminations.

More specifically, SiO ₂ is deposited on a thin film of any one of Hfo, ZrO ₂ , TiO ₂ and TaO ₂ to selectively disperse sunlight having a desired coating wavelength band in the beam splitting coating. If the protective coating film formed is coated with one composite coating layer, the composite coating layer is coated on the surface of the beam splitting coating unit in a plurality of times.

In the present embodiment, the beam splitting coating film may be configured differently according to the solar cell 92 to be installed. For example, when the solar cell 92 includes a crystalline solar cell, light having a low absorbance of crystalline silicon of 1100 nm or more is reflected and light having a wavelength of less than 1100 nm that can be used for power generation is allowed to pass. A beam splitting coating film can be prepared.

On the other hand, when the cell 92 is provided with a thin-film solar cell, the beam splitting coating preferably allows light having a wavelength of less than 900nm to pass through and reflects light of 900nm or more.

Meanwhile, the anti-fouling dustproof coating surface (not shown) may be further formed on the surface of the solar cell protective device 94. When the surface of the solar cell protective device 94 is contaminated by external dust or the like to reduce the transmittance of the solar light, the power generation efficiency of the solar cell is rapidly decreased. Therefore, the surface of the solar cell protection device 94 should be kept clean, but it is very difficult to periodically clean the plurality of solar cell protection devices.

Therefore, by forming an antifouling dust-proof coating surface (not shown in the figure) on the surface of the solar cell protective device 94, it is to prevent contamination by default. The antifouling dust-proof coating surface may be configured in various ways, for example, may be composed of a film having a very small number of properties. The superhydrophobic surface is coated with a hydrophobic material or formed with a structure having fine protrusions of 100 nm or less, so that the contact angle with water is larger than 150 °. When coated with a superhydrophobic film in this way, the external contaminants do not adhere to the surface of the solar cell protection device, and some attached contaminants are naturally washed by rain or the like.
