Description

Technical Field

[0001] The invention relates to the technical field of cable installation, and in particular to an adjustable intelligent cable trench cover. Background Art

[0002] Cable trench covers are objects used to form a seal above the cable trench; they are generally available in concrete, metal, and non-metal forms. While being sealed, they have good insulation and safety. Non-metallic cable trench covers are currently widely used. During the use of cables, regular or periodic inspections and maintenance are required, and timely feedback and processing are required when abnormalities are found.

[0003] At present, conventional cable trench covers only have a protective effect and cannot provide assistance for cable inspection and other operations. Therefore, people have designed some intelligent cable trench covers in combination with Internet of Things technology and sensor technology. For example, the patent with application number "2022231452556" discloses an intelligent cable trench cover; it includes a panel, a plurality of reinforcing ribs are fixed at the bottom of the panel, a plurality of reinforcing ribs are designed with through holes, steel bars are fixed in the through holes, the steel bars and concrete are cast and fixed, the panel and concrete are fixed with a first edge and a second edge, and an electronic control module, a smoke sensor module, a temperature sensor module, a water immersion module, a power supply module and a network communication module are installed at the bottom of the reinforcing ribs; the introduction of an electronic information control system can detect the temperature, fireworks and water immersion in the cable trench at any time. The patent with application number "2024200124022" discloses an intelligent cable trench cover, including a main body and an intelligent mechanism. The intelligent mechanism is arranged inside the main body, and a bottom protective cover is arranged under the main body. Through the setting of the control component, it can cooperate with other components to work. Once an abnormal situation is found, it is also convenient for personnel to monitor the internal cables. Through the setting of the anti-theft component, the cable line can be protected from unauthorized access and damage, which helps to ensure the safe operation of the cable and reduce potential criminal activities. At the same time, through the setting of the alarm component, in the event of an emergency, the infrared monitoring component can be used to monitor the real-time status of the cable line through infrared to avoid damage to the cable line and cause losses. Through the setting of the environmental monitoring component, the working environment of the cable line can be monitored in real time, so that the staff can find and solve the problem in the first time.

[0048] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0049] Reference Figure 1-25 , an adjustable intelligent cable trench cover, comprising two end plates 1 and a middle plate 2 sandwiched between the two end plates 1, and a long strip structure formed by three plates; when in use, the cable trench covers are arranged in sequence; Figure 1 , Figure 2 , Figure 3 As shown, the cable trench cover is arranged above the cable trench, and its two ends are supported on the cable trench to form a stable placement.

[0050] Among them, a telescopic structure 3 that cooperates with each other is set at the lower end of the end plate 1; thereby, the distance between the two end plates 1 is adjusted; and a middle plate 2 of appropriate size is placed between the two end plates 1 to form a complete cover plate structure.

[0051] Furthermore, the middle plate 2 is transparent (eg, highly transparent acrylic); thus, the internal conditions of the cable trench can be observed without opening the cover, which is extremely convenient for inspection operations; and can assist operators to promptly discover problems inside the cable trench.

[0052] It should be noted that, when the operator is inspecting, light can be irradiated inward through the middle plate 2 (eg, using a flashlight) to better observe the internal cable conditions.

[0053] In addition, a solar panel 4 is embedded in the middle plate 2 ; and the area of ​​the solar panel 4 is smaller than that of the middle plate 2 , and a portion of the middle plate 2 forms a perspective area; thus, the solar panel 4 provides energy supply to each component.

[0054] It should be noted that the solar panel 4 embedded in the middle plate 2 has its top surface protected by the middle plate 2, can absorb light, and will not be damaged by the external environment; preferably, a groove is opened on the lower end surface of the middle plate 2 to embed and install the solar panel 4.

[0055] In some embodiments, both sides of the end plate 1 are respectively provided with mutually matching bite structures 5, so that the adjacent cover plates are tightly combined, and the overall effect is better.

[0056] Furthermore, electrical contacts 6 are provided on the opposite surfaces of the bite structure 5 .

[0057] Thus, each cable trench cover is interconnected; even if the cable trench covers in a certain area have insufficient energy storage due to light or other reasons, they can supply each other to ensure the coordinated use of all cable trench covers.

[0058] In addition, the electrical contacts 6 can not only realize the coordination of power supply, but also transmit information to each other; thereby, the various cable trench covers are interacted and combined to realize the collection of distributed data.

[0059] In some embodiments, a battery 11 is installed at the lower end of the end plate 1, and a vibration sensor, a temperature sensor, a humidity sensor, etc. are installed below the end plate 1 to collect environmental information for monitoring. For example, continuous vibration is very likely to produce adverse effects, and abnormal temperature and humidity may be caused by cable overheating, flooding, etc.

[0060] It can be understood that in order to realize the corresponding information collection and other functions, each cable trench cover needs to be equipped with a control board; each control board has certain computing and processing capabilities; in the above setting, they are connected into a group of cable trench covers, and their collected data can be comprehensively analyzed to obtain more accurate and reliable information.

[0061] For example, based on the temperature or humidity changes at various locations, the area where the abnormality occurs can be preliminarily analyzed; based on the vibration range and intensity, the location of the influencing source can be preliminarily determined; and so on.

[0062] In some embodiments, a reinforcement strip is provided at the lower end of the end plate 1; Figure 6 , Figure 8 As shown, the reinforcing strips are multiple crisscrossing ribs, which cooperate with the panel to significantly improve the overall strength; and, compartments are formed between the reinforcing strips, which can be used to assemble sensors, batteries and other components.

[0063] In some embodiments, light sensors 12 are respectively disposed on both sides of the lower side of the end plate 1 close to the outer end.

[0064] It should be noted that, under normal circumstances, the inside of the cable trench is relatively dark, and the changes in internal illumination are relatively regular; therefore, a light sensor 12 is provided on both sides of the end to monitor abnormal external illumination changes; such as, the cable trench cover being lifted, open flames appearing in the cable trench, etc.

[0065] In addition, the light sensor 12 of the cable trench cover can also cooperate with the fill light operation; for example, a light bar is provided at the lower end of the end plate 1; the light sensor 12 controls the brightness of the light bar according to the monitoring information, so that the interior is always in a good observation state; combined with the transparent middle plate 2, it is more convenient for inspection operations; and, the present application is powered by solar energy, and the energy supply of the light bar generally will not be a problem.

[0066] Among them, the light strips are arranged around the cables to obtain a better visual environment.

[0067] It is understandable that the light strip adopts a flexible form and can be freely and reasonably arranged.

[0068] In some embodiments, the telescopic structure 3 includes: an inserting tube portion 31 located at the lower end of one end plate 1 , and a latch portion 32 located at the lower end of the other end plate 1 .

[0069] like Figure 6 , Figure 8 , Fig. 9 As shown; the latch portion 32 is integrally arranged at the lower end of one end plate 1 and extends inward; the latch portion 32 is inserted into the insert tube portion 31 of the other end plate 1 and slides to form a connection relationship and a supporting form in the middle position.

[0070] Optionally, a pressing bolt 33 is provided near the inner end of the latch portion 32 to lock the telescopic shape.

[0071] Furthermore, the telescopic structure 3 also includes: an internal threaded barrel 34 located below the end plate 1 and opening toward the middle, and a positive and negative threaded rod 35 cooperating with the internal threaded barrel 34; through the threaded connection form, the telescopic adjustment form can be simply locked.

[0072] Furthermore, a multi-edge section 36 is provided in the middle of the positive and negative threaded rod 35 to facilitate operation thereof.

[0073] When in use, the two end plates 1 are driven to move by rotating the forward and reverse screw rods 35 ; depending on the shape of the forward and reverse screw rods 35 , the two end plates 1 are relatively close to or far away from each other.

[0074] It should be noted that the middle plate 2 is installed after the interval between the two end plates 1 is adjusted; through the adjustable form of the present application, it is only necessary to design an end plate 1 of one specification and then match it with different middle plates 2 to achieve spans of various specifications.

[0075] It should be noted that various sensors, control panels, batteries and other components are designed on the end plate 1; if the specifications of the end plate 1 are adjusted, many components need to be redesigned accordingly; in the solution of the present application, a middle plate 2 that does not require the coordination of many components is used, which greatly simplifies the adaptation cost of cable trenches of different specifications.

[0076] In some embodiments, the lower end of the end plate 1 is equipped with a hook 7 facing outward; thereby, in conjunction with the telescopic adjustment of the present application, better placement, fixation, and a certain degree of theft prevention can be achieved.

[0077] It should be noted that a slot is provided on the side wall of the cable trench corresponding to the hook 7 .

[0078] Preferably, the hook 7 comprises: a mounting plate, a vertical section, an arc section and a horizontal section.

[0079] Among them, the assembly plate cooperates with the lower end of the end plate 1; preferably, a flat plate is used in combination with bolts for assembly; the vertical section is integrally arranged at the lower end of the assembly plate to form a downward extension; the horizontal section is fitted into the side wall slot of the cable trench; the arc section connects the vertical section and the horizontal section.

[0080] Preferably, each end plate 1 is equipped with no less than two hooks 7 to achieve a balanced clamping configuration.

[0081] It can be understood that when in use, the two end plates 1 in the pre-state are relatively close; they are initially placed above the cable trench, and then the distance between the two end plates 1 is adjusted by the telescopic structure 3, so that the hooks 7 at both ends are gradually placed in the slots; then, the middle plate 2 is assembled in place.

[0082] Preferably, a clamping plate 13 with an opening or a hole is horizontally arranged on opposite sides of the two end plates 1 , and a clamping column inserted into the clamping plate 13 is arranged at the lower end of the middle plate 2 .

[0083] like Figure 8-Figure 12 As shown; the card plate 13 forms a support, and its upper end surface is flush with the upper end surface of the latch portion 32, and together they form a support for the middle plate 2; the card column of the middle plate 2 is inserted into the card plate 13 to form a fixed.

[0084] In addition, screws may be arranged above the middle plate 2 to form a threaded connection with the clamping plate 13; in this case, the opening of the clamping plate 13 is a threaded hole.

[0085] In some embodiments, a triangular support bracket having a flat support surface is mounted on the positive and negative threaded rods 35 to further strengthen the support for the centering plate 2 .

[0086] The support bracket includes: a first support bracket 37 and a second support bracket 38 ; the central opening of the first support bracket 37 cooperates with the multi-edge section 36 ; the central opening of the second support bracket 38 cooperates with the outer diameter of the positive and negative threaded rod 35 .

[0087] In the installed state, the first support bracket 37 is sleeved on the multi-edge section 36 ; the second support bracket 38 is sleeved on the positive and negative threaded rods 35 .

[0088] It should be noted that since the rotational position of the positive and negative screw rods 35 is uncertain, before being adjusted into place, the first support bracket 37 is mounted on the positive and negative screw rods 35, and its central opening is larger than the outer diameter of the positive and negative screw rods 35; after the overall length is adjusted into place, the first support bracket 37 is mounted on the multi-sided section 36.

[0089] In addition, in order to better match the rotational position of the positive and negative threaded rods 35, the multi-edge section 36 has no less than six edges, so that it is easier to match and adjust the first support bracket 37 to form a horizontal support surface.

[0090] In some embodiments, two electric contact strips 41 connected to the solar panel 4 are disposed at the lower end of the middle plate 2 ; and the extension direction of the electric contact strips 41 is consistent with the axial direction of the positive and negative threaded rods 35 .

[0091] In addition, an electrical contact 6 is provided at the upper end of the support bracket in cooperation with the electrical contact strip 41 to achieve connection with the solar panel 4 .

[0092] It can be understood that the lower end of the support bracket is provided with an electric wire connected to the battery 11 and is provided with a charging plate in cooperation therewith.

[0093] In the arrangement of the present application, the cooperation of the middle plate 2 is further simple, convenient and reliable.

[0094] It should be noted that the electric wires can be arranged on any one of the support brackets; similarly, the electric wires can also be arranged on multiple support brackets to form a multi-level guarantee, which is more stable and reliable.

[0095] In some embodiments, the interlocking structure 5 includes: a lower slat 51 on one side, and an upper slat 52 on the other side; wherein the opposing surfaces of the lower slat 51 and the upper slat 52 are inclined surfaces; in the mating state, the inclined surfaces are used to pull the two cable trench covers closer to each other so that they fit tightly.

[0096] Furthermore, sealing grooves are provided on the opposite surfaces of the upper slat 52 and the end plate 1 ; correspondingly, sealing strips are provided on the sealing grooves of the upper slat 52 or the end plate 1 to achieve a good sealing effect and reduce the entry of rainwater into the interior of the bite structure 5 .

[0097] Furthermore, a countersunk hole is formed on the top surface of the upper plate 52 and is provided with a positioning nail 53 penetrating downward.

[0098] Thus, high-reliability occlusal docking is achieved through the positioning pins 53; preferably, the positioning pins 53 can be screws, and threaded holes are provided on the lower strips 51 to cooperate with and connect with the screws.

[0099] In some embodiments, at least two pressure sensors 14 are disposed on the end elevation of the end plate 1; correspondingly, the top of the cable trench is grooved, and the end plate 1 is placed inside; the pressure sensor 14 is placed on the side wall of the top groove of the cable trench.

[0100] Therefore, the placement status of the cable trench cover can be monitored in real time through the data of the two pressure sensors 14; and can be coordinated with the vibration sensor to assist in determining the location of the vibration source; for example, if the pressure sensor 14 at one end of the cable trench cover changes more obviously, the vibration source is more likely to appear on that side.

[0101] Furthermore, no less than two pressure sensors 14 are provided in the support contact area of ​​the end plate 1; the pressure sensors 14 cooperate with each other to monitor the placement state of the cable trench cover.

[0102] In some embodiments, a countersunk hole is formed on the outer end surface of the end plate 1 and an elastic rod 8 is installed thereon.

[0103] like Figure 4 , Figure 6 As shown, the elastic rod 8 extends outwards to further enhance the stability of placement.

[0104] In addition, holes can be optionally opened on the side walls of the top slot of the cable trench to facilitate the insertion of the elastic rod 8, thereby further enhancing the stability of placement.

[0105] It can be understood that the elastic rod is pushed outward by the spring; Fig.21 As shown, one end of the spring presses against the bottom of the countersunk hole, and the other end presses against the limiting ring of the elastic rod; the elastic rod is pushed outward.

[0106] Furthermore, the rear end of the elastic rod 8 penetrates to the inner end and is equipped with an adjusting nut.

[0107] like Fig. 20 , Fig.21 As shown; by adjusting the nut, the maximum extension of the elastic rod can be controlled.

[0108] In some embodiments, a near field communication sensing area 15 is disposed on the upper end surface of the end plate 1 .

[0109] Preferably, the near field communication sensing area 15 adopts RFID technology; the operator communicates with it after interactive identification through the inspection terminal; the inspection terminal can realize sign-in, and the near field communication sensing area 15 can send recent collected data to the inspection terminal.

[0110] In addition, a Bluetooth module can also be provided in the near-field communication sensing area 15 to realize a senseless connection between the inspection terminal and the cable trench cover and perform data communication.

[0111] In some embodiments, a fluorescent strip 16 is disposed at the upper edge of the end plate 1 .

[0112] like Figure 7 The fluorescent strips 16 at both ends strengthen the identification and indication.

[0113] In some embodiments, a warning LED light 17 is embedded in the upper end surface of the end plate 1 .

[0114] It is understandable that the warning LED light 17 is off in normal state, or is set to one color, indicating normal operation; when an abnormal situation occurs, the light is turned on for prompting.

[0115] In some embodiments, a through observation hole 18 is provided on the end plate 1; the operator can use an endoscope camera or other mechanism to penetrate the cable trench cover plate to conduct inspection and other operations in-depth inside without opening the cover plate.

[0116] It is understandable that, under normal conditions, a plug 19 is installed in the observation hole 18 to form a blockage.

[0117] Preferably, a plurality of observation holes 18 are provided to make the use more flexible and convenient.

[0118] In some embodiments, the end plate 1 is provided with an expansion connection port 9 connected to the lower end, which is used for assembling different expansion components 91 according to requirements.

[0119] Preferably, the top end of the extended connection port 9 protrudes from the end plate 1, which can reduce the occurrence of rainwater and the like penetrating into the interior.

[0120] In normal state, a sealing plate is installed in the extension connection port 9 to form a closed state.

[0121] In some embodiments, the extended connection port 9 is an internally threaded cylinder, and the extended component 91 is installed on the internal thread of the extended connection port 9 .

[0122] like Fig.19 As shown, the extension component 91 is an exhaust pipe; wherein the exhaust pipe includes: a lower thread ring and a cone top connected together by a connecting section.

[0123] In some embodiments, an edge sealing member 10 is mounted on the lower plate strip 51 of the cable trench cover at the edgemost position.

[0124] like Figure 23-Figure 25 The inner side of the edge banding member 10 cooperates with the lower strip 51 and is also provided with an electrical contact 6 and is equipped with a positioning nail 53.

[0125] It should be noted that the edge sealing member 10 is also a type of expansion component; when the cable trench covers are interconnected, a communication module is provided in the edge sealing member 10 to aggregate the data of the cable trench covers and send them to the cloud.

[0126] It can be understood that the cable trench cover provides power to the edge sealing member 10 for communication interaction, and the communication module can be a suitable product on the market and encapsulated in the edge sealing member 10.

[0127] In addition, a storage module, as well as an on-site communication and / or wired communication interface can also be set in the edge sealing member 10; thus, after a certain period of time, the edge sealing member 10 can be removed and the internal storage information can be read; it can be understood that the information of each cable trench cover is summarized and stored in the edge sealing member 10.
