Description

Technical Field

[0001] This application relates to the field of communication infrastructure technology, specifically to an intelligent anti-theft manhole cover and manhole cover assembly. Background Technology

[0002] Pipeline resources are a crucial strategic resource for operators, but manholes are essentially "dumb" resources, unable to automatically report their operational status. When pipelines are occupied, operators cannot intervene immediately. Furthermore, due to the lack of efficient monitoring methods for pipeline resources, operators face high costs for daily maintenance, inspection, repair, and management of manholes. Additionally, missing, incompletely closed, or improperly restored manhole covers can pose safety hazards to pedestrians and vehicles on the road.

[0003] Therefore, existing manhole covers lack effective monitoring methods. When a manhole cover is stolen or forcibly opened, the operator cannot promptly understand the specific situation of the manhole cover, which requires further improvement. Utility Model Content

[0036] The features and exemplary embodiments of various aspects of the present invention will now be described in detail. Furthermore, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.

[0037] The intelligent anti-theft manhole cover of this application embodiment will be further described below with reference to the accompanying drawings.

[0038] Figure 1 The overall disassembly structure of an intelligent anti-theft manhole cover 100 provided in the first aspect embodiment of this application is shown.

[0039] Please see Figure 1 In one aspect, embodiments of this application provide an intelligent anti-theft manhole cover 100, including a main cover 10, a secondary cover 20, and a detection component 30.

[0040] The main cover 10 includes a mounting groove 11 and a locking structure 12. The mounting groove 11 is located on the side wall of the main cover 10, and the locking structure 12 is installed in the mounting groove 11. The secondary cover 20 includes a locking tongue 21, which is located on the side wall of the secondary cover 20. The detection component 30 is embedded in a reserved slot on the side wall of the main cover 10 and / or the covered side wall.

[0041] In the locked state, the detection component 30 is in a safe state, and the locking tongue 21 extends into the mounting groove 11 and is locked and fixed with the locking structure 12.

[0042] When unlocked, the detection component 30 is activated and sends back an alarm message.

[0043] Firstly, in the intelligent anti-theft manhole cover 100 provided in this application embodiment, when locked, the signal detected by the detection component 30 fluctuates within a preset threshold and is in a safe state when the locking structure 12 and the locking tongue 21 on the main cover 10 and the secondary cover 20 are locked; while in the unlocked state, when the locking relationship between the main cover 10 and the secondary cover 20 is released, the signal detected by the detection component 30 exceeds the preset threshold and sends back an alarm message, and is in an active state. This realizes the linkage between the safe mode and the active mode of the detection component 30 and the locked and unlocked states of the intelligent anti-theft manhole cover 100 achieved by the locking structure 12 and the locking tongue 21. Operators can remotely know the opening and closing status of the intelligent anti-theft manhole cover 100, realize real-time monitoring of the opening and closing status, and reduce operation and maintenance costs.

[0044] The intelligent anti-theft manhole cover 100 provided in the first aspect of this application utilizes the installation space with a certain thickness of the main cover 10 and the secondary cover 20. An installation groove 11 is provided on the side wall of the main cover 10, a locking tongue 21 is provided on the side wall of the secondary cover 20, and a slot is reserved for the detection component 30 on the side wall. This can make full use of the existing manhole cover structure and realize a reasonable layout of the installation positions of the locking structure 12, the locking tongue 21 and the detection component 30.

[0045] First, the locking structure 12 and the locking tongue 21 are installed on the side walls of the main cover 10 and the secondary cover 20, which makes it easy for the main cover 10 and the secondary cover 20 to achieve a stable locking connection during actual use, and the connection between the locking structure 12 and the locking tongue 21 is not easily affected by other external interference factors.

[0046] Secondly, the detection component 30 is embedded in the reserved slot on the side wall of the main cover 10 and / or the secondary cover 20. The installation position is concealed and not easy to be removed in advance. At the same time, the installation position of the detection component 30 is closer to the edge of the main cover 10 and / or the secondary cover 20, so that when the intelligent manhole cover switches between the locked and unlocked states, the signal fluctuations that the detection component 30 can detect are more obvious and the detection sensitivity is higher.

[0047] In this embodiment, the "safe state" and "active state" of the detection component 30 should be understood as the detection component 30 employing a negative triggering mechanism. When the signal detected by the detection component 30 fluctuates within a preset threshold range, the detection component 30 is in a safe state and will not trigger the corresponding alarm function; when the signal detected by the detection component 30 exceeds the preset threshold range, the detection component 30 switches to an active state and sends back an alarm message.

[0048] For example, the detection components 30 are respectively disposed in the reserved slots on the side walls of the main cover 10 and the secondary cover 20. The signals of the detection components 30 located on the side wall of the main cover 10 and the detection components 30 located on the side wall of the secondary cover 20 interact with each other, so that the detection components 30 are kept in a safe state.

[0049] When the intelligent anti-theft manhole cover 100 is opened, the positions of the main cover 10 and the secondary cover 20 deviate, and the signals interacting between the two deviate. When the signal deviation exceeds the preset threshold, the detection component 30 embedded in the reserved slots on the side walls of the main cover 10 and the secondary cover 20 can detect the abnormality at the first moment when the intelligent anti-theft manhole cover 100 is opened, enter the activation state, and send back an alarm message.

[0050] An embodiment in which the detection component 30 is arranged on both the main cover 10 and the secondary cover 20 will be further described in other embodiments provided in the first aspect of this application below.

[0051] Optionally, the detection component 30 is separately set in a reserved slot on the side wall of the main cover 10. The detection component 30 can be set as an accelerometer or a tilt sensor. The detection component 30 embedded in the reserved slot on the side wall of the main cover 10 is more sensitive because it is located at the edge of the main cover 10. It can detect the abnormality at the first time when the intelligent anti-theft manhole cover 100 is opened, enter the activation state and send back an alarm message.

[0052] Optionally, the detection component 30 is separately set in a reserved slot on the side wall of the sub-cover 20. The detection component 30 can be set as an accelerometer or a tilt sensor. The detection component 30 embedded in the reserved slot on the side wall of the sub-cover 20 is more sensitive because it is located at the edge of the sub-cover 20. It can detect the abnormality at the first time when the intelligent anti-theft manhole cover 100 is opened, enter the activation state and send back an alarm message.

[0053] Please continue reading. Figure 1In some embodiments, the main cover 10 and the secondary cover 20 are square manhole covers. The mounting groove 11, the locking structure 12 and the locking tongue 21 include two sets. The two mounting grooves 11 and the locking structure 12 on the main cover 10 are located on the same side wall, and the two locking tongues 21 on the secondary cover 20 are located on the same side wall. The main cover 10 and the secondary cover 20 are arranged side by side. The detection component 30 is located between the two mounting grooves 11, and / or the detection component 30 is located between the two locking tongues 21.

[0054] In these embodiments, the cooperation between the locking structure 12 and the locking tongue 21 and the setting position of the detection component 30 can further realize the stable locking of the intelligent anti-theft manhole cover 100 in the locked state, and further avoid the risk of the detection component 30 being removed in advance. When the intelligent anti-theft manhole cover 100 is in the unlocked state, the detection component 30 can further detect the abnormality and send back an alarm message as soon as possible.

[0055] For example, the main cover 10 and the secondary cover 20 are square manhole covers. After the main cover 10 and the secondary cover 20 are arranged side by side, the length of the side walls of the two are more sufficient. After the locking structure 12, the latch 21 and the detection component 30 are arranged according to the arrangement of this embodiment, the detection component 30 is located between the locking structure 12 and the latch 21 for locking and fixing, and the anti-theft effect can be better achieved.

[0056] For example, the main cover 10 and the secondary cover 20 are used in a communication hand well, that is, the size of the well opening 220 is limited to the size range that allows an operator to enter the well for operation.

[0057] Optionally, the main cover 10 and the secondary cover 20 are also used in communication manholes, i.e., the size of the manhole opening 220 is limited to the size range that allows one operator to enter the manhole for operation.

[0058] Figure 2 It shows Figure 1 Enlarged structure at the positions of mounting slot 11 and fixing base 120.

[0059] Please see Figure 1 and Figure 2 In some embodiments, the mounting groove 11 is provided through the main cover 10 along the thickness direction Z. The locking structure 12 includes a fixing seat 120 and a lock 121. The fixing seat 120 is installed on one side of the mounting groove 11 along the thickness direction Z. The lock 121 is fixed on the fixing seat 120 and extends through the reserved hole on the fixing seat 120 to the other side of the mounting groove 11 along the thickness direction Z.

[0060] In the locked state, the bolt 21 extends into the lock 121 and is locked and fixed with the lock 121.

[0061] In these embodiments, a mounting base 120 for fixing the lock 121 is provided in the mounting groove 11. The lock 121 can extend from the side of the mounting groove 11 where the mounting base 120 is installed to the other side of the mounting groove 11 along the thickness direction Z. This allows the locking arrangement of the latch 21 on the sub-cover 20 and the corresponding locking arrangement of the lock 121 to have a certain operational redundancy space, increasing the allowable error range of operation, thereby improving assembly efficiency and further reducing maintenance costs.

[0062] Please continue reading. Figure 1 and Figure 2 In some embodiments, the latch 21 includes two protruding ends 211 that extend along a first direction X. The lock 121 includes a lock head 121a, an extension shaft 121b, and a lock body 121c connected along the thickness direction Z. The lock head 121a is located on the side of the mounting base 120 away from the mounting groove 11. The extension shaft 121b passes through a reserved hole on the mounting base 120 and extends. The lock body 121c is located in the mounting groove 11 on the side opposite to the mounting base 120 along the thickness direction Z.

[0063] In the locked state, the extension shaft 121b is located between the two protruding ends 211, and the lock 121 rotates until the lock body 121c extends along the second direction Y, where the first direction X and the second direction Y intersect.

[0064] In the unlocked state, the lock 121 rotates until the lock body 121c extends along the first direction X.

[0065] In these embodiments, the intelligent anti-theft manhole cover 100 provided in this application embodiment can switch between locked and unlocked states by rotating the extension direction of the lock body 121c between the first direction X and the second direction Y.

[0066] The operator rotates the lock head 121a in the lock 121. The rotation of the lock head 121a drives the extension shaft 121b to rotate, which in turn drives the lock body 121c to rotate. When the lock body 121c extends along the second direction Y, the operator attempts to open the intelligent anti-theft manhole cover 100 provided in this application embodiment. The lock body 121c and the lock tongue 21 extend into the protruding ends 211 on both sides of the extension shaft 121b along the first direction X. The lock body 121c and the protruding ends 211 interfere with each other, and the intelligent anti-theft manhole cover 100 provided in this application embodiment remains in the locked state.

[0067] When the lock body 121c is rotated to extend along the first direction X, the operator attempts to open the intelligent anti-theft manhole cover 100 provided in this application embodiment. The lock body 121c and the extended end 211 can avoid the risk of mutual interference and switch the intelligent anti-theft manhole cover 100 provided in this application embodiment to the locked state.

[0068] For example, the lock body 121c is a crossbar structure, and the lock body 121c and the extension shaft 121b form an inverted "T" shaped structure, which is simple and reliable.

[0069] For example, the extension shaft 121b is a threaded rod, and the lock 121 can pass through the fixing seat 120 through the threaded structure on the extension shaft 121b. When further secure fixing is required, a nut or other parts can be added to achieve a more secure and reliable installation.

[0070] For example, the length of the protruding end 211 is less than the depth of the mounting groove 11, and the width of the mounting groove 11 is greater than the width of the lock 121, so as to reserve a certain amount of redundant space for the assembly of the lock 121 and the protruding end 211.

[0071] For example, to make it clear, the first direction X and the second direction Y are perpendicular to each other.

[0072] The designation of the directions as the first direction X and the second direction Y is merely for illustrative purposes. The intelligent anti-theft manhole cover 100 provided in the first aspect embodiment of this application does not impose any restrictions on the specific settings of the first direction X and the second direction Y. It is only necessary to ensure that the first direction X and the second direction Y intersect and are not the same or opposite directions.

[0073] Meanwhile, in this embodiment, the lock body 121c extends along the first direction X, or the lock body 121c extends along the second direction Y. It should be understood that due to the low precision of manual operation by the operator, and the rotation of the lock head 121a to drive the extension shaft 121b to rotate the lock body 121c, the lock body 121c extends at an angle that offsets to both sides by no more than a preset error value with the first direction X or the second direction Y as a reference. The lock body 121c is regarded as extending along the first direction X or the second direction Y.

[0074] In fact, since there is a certain preset width between the two protruding ends 211, even if there is a deviation in the angle within a certain range, the lock body 121c and the protruding ends 211 can still keep the intelligent anti-theft manhole cover 100 provided in this application embodiment in a locked or unlocked state.

[0075] Figure 3 The side view of the main cover 10 structure of another intelligent anti-theft manhole cover 100 provided in the first aspect embodiment of this application is shown.

[0076] Please see Figure 3 In some embodiments, the lock 121 also includes a lock key 121d, the shape of which is adapted to the shape of the lock head 121a. In the unlocked state, the lock key 121d is engaged with the lock head 121a and drives the lock 121 to rotate.

[0077] In these embodiments, the operator can only rotate and drive the lock head 121a by using a lock key 121d that matches the shape of the lock head 121a, thereby enabling the intelligent anti-theft manhole cover 100 to switch between the locked and unlocked states. This further enhances the anti-theft security performance of the intelligent anti-theft manhole cover 100, while providing the lock key 121d can further help the operator improve work efficiency and further reduce maintenance costs.

[0078] Figure 4 The module principle of the detection component 30 of another intelligent anti-theft manhole cover 100 provided in the first aspect of this application is shown.

[0079] Please see Figure 4 In some embodiments, the detection component 30 includes a communication module 33, a receiver 32, and a transmitter 31. The receiver 32 is disposed on the side wall of one of the main cover 10 and the secondary cover 20, and the transmitter 31 is disposed on the side wall of the other.

[0080] In the locked state, the transmitter 31 and receiver 32 are physically coupled continuously, the detection component 30 is in a safe state, and the communication module 33 is in a sleep mode.

[0081] In the unlocked state, the physical coupling between the transmitter 31 and the receiver 32 is interrupted, the detection component 30 is activated, and the communication module 33 is activated and sends back an alarm message.

[0082] In these embodiments, the detection component 30 adopts a negative feedback operation combining the transmitter 31 and the receiver 32. In the safe mode, the receiver 32 continuously receives the signal from the transmitter 31 so that the communication module 33 remains in sleep mode.

[0083] When the intelligent anti-theft manhole cover 100 is opened, the receiver 32 cannot receive the signal from the transmitter 31. After the connection is interrupted, in the activation mode, the communication module 33 is activated and sends back an alarm message. This further realizes the linkage between the security mode and activation mode of the detection component 30 and the locking and unlocking states of the intelligent anti-theft manhole cover 100 through the locking structure 12 and the locking tongue 21, further improving the anti-theft security performance of the intelligent anti-theft manhole cover 100 and further reducing the operation and maintenance costs.

[0084] The “physical coupling” here should be understood as the interaction between the receiver 32 and the transmitter 31 through physical signals. That is, the receiver 32 continuously receives physical signals emitted by the transmitter 31, so that the detection component 30 is kept in a safe state. Physical signals refer to optical, electrical, magnetic signals, etc.

[0085] "Physical coupling interruption" means that the transmitter 31 is unable to send the corresponding physical signal, or the receiver 32 is unable to receive the corresponding physical signal sent by the transmitter 31, and the interaction between the physical signals of the transmitter 31 and the receiver 32 is interrupted.

[0086] Through the physical coupling of the transmitter 31 and receiver 32 in the detection component 30, the detection component 30 can monitor the opening and closing status of the intelligent anti-theft manhole cover 100 in real time. When the intelligent anti-theft manhole cover 100 is opened, the communication module 33 in the detection component 30 is activated and sends back an alarm message. Operators can rush to the scene to intervene as soon as possible, realizing the automatic monitoring function of pipeline resources.

[0087] Alternatively, a receiver 32 and a transmitter 31 are provided on the side walls of both the main cover 10 and the secondary cover 20. The two sets of receivers 32 and transmitters 31 are physically coupled at the same time, thereby further improving the anti-theft security performance of the intelligent anti-theft manhole cover 100 and further reducing the operation and maintenance costs.

[0088] In some embodiments, the transmitter 31 is a magnet and the receiver 32 is a reed switch. In the locked state, the receiver 32 continuously receives the magnetic field signal from the transmitter 31 and is in a closed state. Alternatively, the transmitter 31 is an infrared transmitter and the receiver 32 is an infrared receiver. In the locked state, the receiver 32 continuously receives the infrared signal from the transmitter 31.

[0089] In these embodiments, the receiver 32 and transmitter 31, which use infrared or magnetic signals to interact, are more concealed. At the same time, the infrared or magnetic signals are less susceptible to interference from external factors. This allows for real-time monitoring of the opening and closing status of the intelligent anti-theft manhole cover 100 at low cost, further improving the anti-theft security performance of the intelligent anti-theft manhole cover 100 and thus further reducing maintenance costs.

[0090] For example, the transmitter 31 is a magnet and the receiver 32 is a reed switch. In the locked state, the receiver 32 continuously receives the magnetic field signal from the transmitter 31 and is in a closed state, and the communication module 33 is in a sleep mode. In the unlocked state, the magnetic field signal received by the receiver 32 from the transmitter 31 is interrupted, the communication module 33 is activated and sends back an alarm message.

[0091] For example, the transmitter is an infrared transmitter and the receiver 32 is an infrared receiver. In the locked state, the receiver 32 continuously receives the infrared signal from the transmitter 31 and sends a suppression signal to the communication module 33, which is in sleep mode. In the unlocked state, the infrared signal received by the receiver 32 from the transmitter 31 is interrupted, the communication module 33 is activated and sends back an alarm message.

[0092] Figure 5This invention illustrates an overall disassembly structure of another intelligent anti-theft manhole cover 100 provided in the first aspect embodiment of this application. Figure 6 It shows Figure 5 The first cover 20a has a structure at another angle.

[0093] Please see Figure 5 and Figure 6 In some embodiments, the secondary cover 20 further includes a first secondary cover 20a and a second secondary cover 20b. The locking tongue 21 is located on the first secondary cover 20a. The first secondary cover 20a includes a insertion hole 22, which is disposed on the other side wall of the first secondary cover 20a opposite to the locking tongue 21. The second secondary cover 20b further includes a insertion part 23, which is located on the side wall of the second secondary cover 20b.

[0094] In the locked state, the first cover and the second cover 20b are arranged side by side, the plug part 23 extends into the plug hole 22, and the first cover 20a and the second cover 20b are spliced ​​together.

[0095] In these embodiments, the first sub-cover 20a and the second sub-cover 20b are connected by insertion and splicing. If the operator wants to unlock them in the locked state, he still needs to first unlock the locking structure 12 between the first sub-cover 20a and the main cover 10 and the locking tongue 21 before the first sub-cover 20a and the second sub-cover 20b can be unlocked. This further improves the anti-theft security performance of the intelligent anti-theft manhole cover 100, thereby further reducing the operation and maintenance costs.

[0096] Optionally, the intelligent anti-theft manhole cover 100 includes multiple second auxiliary covers 20b. The second auxiliary covers 20b are all located on the side of the first auxiliary cover 20a away from the main cover 10. The multiple second auxiliary covers 20b are also connected sequentially by plugging and splicing each other. This allows the intelligent anti-theft manhole cover 100 to adapt to manholes 220 of different sizes. When the intelligent anti-theft manhole cover 100 is locked, to unlock it, one must first unlock the locking relationship between the lock 121 and the locking tongue 21 between the first auxiliary cover 20a and the main cover 10, and then unlock the first auxiliary cover 20a and the second auxiliary covers 20b, as well as the splicing relationship between the second auxiliary covers 20b. This further improves the anti-theft security performance of the intelligent anti-theft manhole cover 100, thereby further reducing maintenance costs.

[0097] Please see Figure 1 or Figure 5 In some embodiments, the main cover 10 and the secondary cover 20 also include a body portion 100a and an edge-sealing structure 100b. The edge-sealing structure 100b is disposed around the side wall of the body portion 100a, and the fixing seat 120 is welded to the portion of the edge-sealing structure 100b located in the mounting groove 11.

[0098] In these embodiments, the edge-sealing structure 100b not only enhances the external structure of the main cover 10 and the secondary cover 20, but also provides space for the installation of the fixing seat 120, enabling the fixing seat 120 to be firmly welded, and further improving production efficiency.

[0099] For example, the main body 100a is formed by casting concrete, the edging structure 100b is a steel sheet, and the fixing seat 120 can be directly welded to a portion of the edging structure 100b at the position of the mounting groove 11.

[0100] Figure 7 The overall structure of a manhole cover assembly 200 provided in a second aspect embodiment of this application is shown.

[0101] Please see Figure 7 Secondly, embodiments of this application provide a manhole cover assembly 200, including an intelligent anti-theft manhole cover 100 and a manhole base 210 provided in any of the first aspects of this application. The manhole base 210 encloses to form a manhole opening 220. In the locked state, the main cover 10 and the secondary cover 20 are embedded in the manhole base 210 and seal the manhole opening 220.

[0102] The manhole cover assembly 200 provided in the second aspect of this application includes the intelligent anti-theft manhole cover 100 provided in any of the first aspect of this application, and therefore has the beneficial effects of the intelligent anti-theft manhole cover 100 provided in any of the first aspect of this application, which will not be repeated here.

[0103] The manhole cover assembly 200 has a manhole seat 210 that provides a pre-embedded part for the side of the pipeline near the ground. The operator only needs to bury the manhole seat 210 into the ground to complete the construction of the manhole.

[0104] On the other hand, the size of the intelligent anti-theft manhole cover 100 and the opening size of the manhole base 210 are adapted to each other during the production process, so that the main cover 10 and the auxiliary cover 20 can be smoothly embedded into the manhole base 210 and seal the manhole opening 220 during subsequent installation, which further improves production efficiency and further reduces maintenance costs.
