Description

Technical Field

[0001] The invention relates to a manhole cover water immersion monitoring terminal and an installation method thereof, and relates to the technical field of manhole cover monitoring. Background Art

[0002] Manhole covers are an important part of municipal infrastructure and are closely linked to the vital interests of the general public. With the increasing number of underground pipelines and manhole cover facilities on municipal roads, problems such as manhole cover theft, damage, displacement, and sinking have become increasingly prominent, directly threatening urban roads and the urban environment. As these problems continue to become more prominent, more and more urban pipe networks are replacing traditional manhole covers with smart manhole covers. Common smart manhole covers are ordinary manhole covers with water immersion monitoring terminals installed at the bottom to achieve the functions of smart manhole covers. Common water immersion monitoring terminals have manhole cover tilt detection, theft alarm, and water immersion functions. They are low-power, and their internal batteries can support the normal operation of the device for up to three years, resulting in a long maintenance cycle. At the same time, they can upload the terminal status to the public network base station through the NB-IOT module and forward it to the cloud, allowing users to centrally control data in the cloud.

[0003] In order to ensure the accuracy of data detection and the convenience of use, common manhole cover water immersion monitoring terminals are often installed at the bottom of the manhole cover. The bottom of the manhole cover generally corresponds to the city's sewage well, so it is necessary to ensure that the device will not fall into the sewage well due to external force. Current technology requires that when installing the device, the manhole cover must be removed and the bottom of the manhole cover must be facing upward. A suitable position must be selected and drilled with an electric drill before the device is installed with screws. During the entire installation process, not only does the manhole cover need to be destroyed, but special tools are also required and it takes a long time to complete the installation, making it impossible to quickly disassemble and assemble.

[0004] During normal use, the manhole cover water immersion monitoring terminal is usually installed normally at the bottom of the other manhole covers, and the monitoring terminal is reset before it can be turned on for normal use. However, after actual installation, it is often forgotten to reset it, and the measured data will have a large error. At the same time, after the device is disassembled, it is often forgotten to turn off the power, which will cause unnecessary power consumption of the device and reduce the battery life.

[0036] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0037] See Figures 1 to 8 , provides an easy-to-install manhole cover water immersion monitoring terminal, including a monitoring terminal body 1, a base component 2 arranged above the monitoring terminal body, and a power supply component (not shown) electrically connected to the monitoring terminal body 1.

[0038] The monitoring terminal body 1 is provided with a pull rod 4 in the middle, which passes through the monitoring terminal body 1 and can move relative to the monitoring terminal body 1. A movable plate 3 is provided on the side of the pull rod 4 away from the base assembly 2, and a tilt detection assembly 17 is connected to the movable plate 3.

A return spring 8 is sleeved on the pull rod 4, one end of the return spring 8 abuts against the monitoring terminal body 1, and the other end of the return spring 8 abuts against the movable seat 5. A plurality of first fixed seats 9 are fixedly installed at equal angles on the side of the monitoring terminal body 1 close to the base assembly 2. Each first fixed seat 9 is connected to a support rod 10, and a positioning rod 12 is provided above each support rod 10, and the positioning rod 12 corresponds to the positioning hole 205. A third fixed seat 14 is fixedly installed on the side of each support rod 10 close to the pull rod 4. The third fixed seat 14 and the movable seat 5 are located on the same horizontal line. A connecting rod 15 is connected between the third fixed seat 14 and the movable seat 5, and the connecting rod 15 can move relative to the third fixed seat 14 and the movable seat 5.

[0039] Among them, the base component 2 is used to fix to the manhole cover, and the base component 2 is provided with a positioning hole 205 for fixing to the monitoring terminal body 1. Before installing the device, the installation method needs to be determined according to the material type of the manhole cover. When the main material of the manhole cover is made of cast iron, it can be directly fixed by adsorption through the base component 2 to complete the installation. When the main material of the manhole cover is made of concrete or resin, it can be fixed using the screw mounting holes on the base component 2. After completing the pre-installation judgment, the battery power needs to be checked to prepare for installation. Since conventional manhole covers are made of cast iron for durability and cost considerations, this device can meet the quick installation requirements of most manhole covers.

[0040] The base assembly 2 includes a bottom plate 201, which is located at the top of the second fixed seat 11. A vertical plate 204 is fixedly installed at an equal angle at the bottom end of the bottom plate 201. One end of the vertical plate 204 is provided with a completely through positioning hole 205. The positioning rod 12 passes through the positioning hole 205 and is movably engaged with the positioning hole 205. A mounting groove 202 is provided in the middle of the top of the bottom plate 201. A permanent magnet 203 is fixedly installed inside the mounting groove 202. An ear plate 206 is fixedly installed at an equal angle on the outer side surface of the bottom plate 201. A completely through reserved hole 207 is provided inside the ear plate 206.

[0041] In this embodiment, in detail, the bottom end of the pull rod 4 passes through the bottom end of the monitoring terminal body 1 and is fixedly installed with a movable plate 3, and a tilt detection component 17 is provided below the movable plate 3. The top end of the pull rod 4 passes through the top end of the monitoring terminal body 1 and is fixedly installed with a movable seat 5, and the pull rod 4 can slide relative to the monitoring terminal body 1. Four first fixed seats 9 are fixedly installed at equal angles on the bottom end of the monitoring terminal body 1, and the bottom end of the first fixed seat 9 is movably connected to the support rod 10 through a rotating shaft. A third fixed seat 14 is fixedly installed in the middle of the inner side of the support rod 10, and the third fixed seat 14 is on the same horizontal line as the movable seat 5. Four fourth fixed seats 16 are fixedly installed on the outer side of the movable seat 5 at equal angles, one end of the fourth fixed seat 16 is movably connected to the connecting rod 15 through a rotating shaft, and the other end of the connecting rod 15 is movably connected to the third fixed seat 14 through a rotating shaft. The bottom end of the first fixed seat 9 is movably connected to the support rod 10 through a rotating shaft, and the bottom end of the support rod 10 is movably connected to the second fixed seat 11 through a rotating shaft, and the end of the second fixed seat 11 away from the movable seat 5 is fixedly installed with a positioning rod 12, which is made of rubber, and the outer side of the positioning rod 12 is provided with collapse grooves 13 at equal distances. It should be noted that the number of the first fixing seat 9, the second fixing seat 11, the third fixing seat 14 and the fourth fixing seat 16 can be modified, but it should be noted that the number of sets must correspond to each other. In other embodiments, each can be set with 5 or 6 or other numbers.

[0042] The tilt detection assembly 17 includes a mounting base 171, the top of the mounting base 171 is fixedly connected to the bottom of the movable plate 3, the inner side of the mounting base 171 is fixedly mounted with a connecting shaft 172, the outer side of the connecting shaft 172 is movably connected with a test pen 173, the test pen 173 can rotate relative to the connecting shaft 172, and the test pen 173 is always perpendicular to the ground. The tilt detection assembly 17 also includes a fixing ring 174, the inner side of the fixing ring 174 is fixedly mounted with a chip resistor 175 at an equal angle, and the test pen 1 The bottom end of the outer side surface of 73 contacts the outer side surface of the chip resistor 175. The NB-IOT module is built into the interior of the monitoring terminal body 1. The output end of the tester 173 is electrically connected to the input end of the NB-IOT module. The resistance value of each chip resistor 175 is different. Each chip resistor 175 located on the inner side surface of the fixing ring 174 is symmetrical to each other, and the resistance value decreases from the chip resistors 175 on the left and right ends of the fixing ring 174 to the chip resistor 175 in the middle of the fixing ring 174.

[0043] Among them, an extension rod 6 is fixedly installed on the top of the movable seat 5, and a touch switch 7 is fixedly installed on the top of the extension rod 6. The top of the touch switch 7 is in contact with the bottom of the base assembly 2, and the output end of the touch switch 7 is electrically connected to the power input end of the monitoring terminal body 1.

[0044] During installation, the permanent magnet 203 can be used to adsorb and connect with the middle part of the bottom end of the manhole cover, or the reserved hole 207 opened on the ear plate 206 can be used to fix it with the bottom end of the manhole cover with screws. After the base assembly 2 is fixed, the movable plate 3 can be pulled outward to drive the movable plate 3 and the pull rod 4 to move downward, and the return spring 8 can be compressed. At this time, the movable seat 5 moves downward. Since one end of the movable seat 5 is connected to the connecting rod 15 and one end of the connecting rod 15 is connected to the support rod 10 and the support rod 10 cannot move up and down, and the overall length of the connecting rod 15 remains unchanged, the connecting rod 1 5 deflects downward, and the inner side of the support rod 10 is subjected to a pulling force from below, which drives the support rod 10 to rotate relative to the first fixing seat 9. The support rod 10 then deflects inward and further drives the four second fixing seats 11 to approach the center of the circle and drives the positioning rod 12 to move inward. At this time, the positioning rod 12 is aligned with the positioning hole 205. By loosening the movable plate 3, the reset spring 8 automatically resets and drives the positioning rod 12 to insert into the interior of the positioning hole 205 to complete the engagement. The installation is completed by fixing the four positioning rods 12. Otherwise, the monitoring terminal body 1 can be disassembled. Because the bonding and fixing method of the permanent magnet 203 and the cast iron is a prior art, it will not be described in detail here.

[0045] By utilizing the magnetically adsorbed base assembly 2, it can adapt to most manhole cover installations, and at the same time, the four positioning rods 12 and the positioning holes 205 are used to realize four-point fixation of the monitoring terminal body 1. The monitoring terminal body 1 can be quickly installed by pulling and releasing, and vice versa, it can be disassembled, avoiding the problems of traditional installation requiring special tools for multi-point drilling and long installation time, greatly reducing the installation time and in most cases, the installation can be completed without carrying special tools, significantly improving the installation efficiency, and being suitable for use in large-scale installations.

[0046] When the device is installed, the reset spring 8 automatically restores its deformation without being affected by external force, driving the movable seat 5 to automatically reset. At this time, the extension rod 6 at the top of the movable seat 5 and the touch switch 7 automatically return to their initial positions. At this time, the top of the touch switch 7 is in contact with the bottom of the base plate 201, and the switch of the touch switch 7 is in a closed state. At this time, the monitoring terminal body 1 can be reset and the power is connected. When the device is disassembled, since the monitoring terminal body 1 and the base assembly 2 are in a separated state, the top of the touch switch 7 is no longer in contact with the bottom of the base plate 201. At this time, the power of the monitoring terminal body 1 is disconnected, realizing automatic closing and disconnection of the power supply.

[0047] By directly corresponding the device power on and off by utilizing the device state after installation and the device state after disassembly, the device is in the power-on state after installation is completed and in the power-off state after disassembly, avoiding the problem that traditional devices often forget to reset and power on after installation and power off after disassembly. It can automatically reset and power on after installation and automatically power off after disassembly, reducing the number of operating steps, having a high degree of automation and effectively reducing the power consumption that may be caused when idle.

[0048] When the device is installed, the test pencil 173 is automatically in a vertical relationship with the ground under the action of gravity. At this time, the bottom end of the test pencil 173 contacts the chip resistor 175 in the middle of the fixing ring 174. At this time, the resistance value is in a constant state. When the manhole cover is opened, the manhole cover is in a tilted state, and the test pencil 173 rotates relative to the connecting shaft 172. At this time, the test pencil 173 deflects in the opposite direction of the tilt of the manhole cover, that is, it contacts other chip resistors 175. As the resistance value increases, the current of the test pencil 173 is smaller due to the constant voltage of the test pencil 173. The degree of tilt can be judged by the change in the current value, and the manhole cover opening alarm is completed by transmission through the remote module.

[0049] By utilizing the plumb bob, the electrician's pencil 173 is always perpendicular to the ground, and the always vertical electrician's pencil 173 is brought into contact with the chip resistor 175 of different resistance values, thereby changing the current value of the electrician's pencil 173. Different current values ​​are used to indicate the degree of inclination of the manhole cover, thereby avoiding the problem that traditional devices can only alarm when the manhole cover is opened but cannot monitor the opening angle of the manhole cover. It also avoids the false alarm phenomenon caused by a slight tilt of the manhole cover, and allows it to determine whether the manhole cover is in a larger open state by the tilt angle. It can more accurately monitor the special state of the manhole cover, reduce the survey time of on-site personnel, and improve work efficiency.

[0050] This embodiment also provides a method for installing a manhole cover water immersion monitoring terminal, including the following steps:

[0051] (1) Fix the base assembly to the manhole cover;

[0052] (2) During installation, the movable plate is pulled away from the manhole cover, and the movable plate drives the pull rod to move, compresses the reset spring and drives the movable seat to move away from the manhole cover. The movable seat drives the connecting rod to move synchronously, and drives the support rod to move toward the movable seat, and the positioning rod is aligned with the positioning hole. The movable plate is released, and the reset spring automatically resets and drives the support rod and the positioning rod to move away from the movable seat. When the positioning rod is inserted into the positioning hole, the fixation is completed;

[0053] (3) During disassembly, the movable plate is pulled away from the manhole cover, and the movable plate drives the pull rod to move, compresses the reset spring and drives the movable seat to move away from the manhole cover. The connecting rod is deflected synchronously and drives the support rod to move toward the movable seat, drives the positioning rod away from the positioning hole, releases the fixation, and takes out the monitoring terminal body away from the manhole cover to complete the disassembly.

[0054] It should be noted that the manhole cover water immersion monitoring terminal of this embodiment can be installed on manhole covers of different materials. Before step (1), the installation method must be determined according to the material type of the manhole cover. When the manhole cover is made of cast iron, it is installed by direct adsorption, and when the manhole cover is made of concrete or resin, it is fixed with screws to complete the judgment before installation.

[0055] Step (1) is as follows: when the manhole cover is made of cast iron, the base assembly 2 is fixed by directly adsorbing the permanent magnet 203 and the manhole cover by selecting the middle part of the bottom end of the manhole cover; if the manhole cover is made of concrete or resin material, the base assembly 2 can be fixed by drilling holes at the corresponding positions of the reserved holes 207 and then fixing them with screws, thus completing the preparations before installation;

[0056] Step (2) is to pull the movable plate 3 toward the outside of the device to pull the pull rod 4 toward the outer side of the device. At this time, the return spring 8 is compressed and further drives the movable seat 5 to move downward, and the connecting rod 15 deflects downward, and drives the support rod 10 to deflect inward, and finally drives the four second fixed seats 11 to move closer inward, and makes the positioning rod 12 correspond to the positioning hole 205. At this time, the movable plate 3 is released, and the return spring 8 automatically resets without being affected by external force, and finally drives the second fixed seat 11 and the positioning rod 12 to move outward. When the positioning rod 12 is inserted into the interior of the positioning hole 205, the fixation is completed;

[0057] In step (3), when disassembling, the movable plate 3 can be pulled outward, so that the pull rod 4 and the movable seat 5 are displaced downward. At this time, the support rod 10 deflects inward, and drives the second fixed seat 11 and the positioning rod 12 to deflect inward, and finally drives one end of the positioning rod 12 to leave the inside of the positioning hole 205, releases the fixation, and pulls out the monitoring terminal body 1 downward to separate the device and complete the disassembly.

[0058] In summary, the present application provides a manhole cover water immersion monitoring terminal, including a base assembly and a monitoring terminal body. The monitoring terminal body and the base assembly are fixed by the clamping connection of the positioning rod and the positioning hole. The monitoring terminal body can be quickly installed by the compression and recovery of the reset spring, avoiding the problem of traditional installation requiring special tools for multi-point drilling and long installation time. The installation time is greatly reduced, and the installation can be completed without carrying special tools, which significantly improves the installation efficiency and is suitable for large-scale installation. The reset spring is used to achieve the conjugate energy of automatic reset. The monitoring terminal is installed and fixed. With the reset spring reset, the monitoring terminal automatically resets and then turns on the switch to use normally. There will be no error in the measurement data caused by forgetting to reset.

[0059] The present application also provides an installation method for the manhole cover water immersion monitoring terminal as described above, in which the state of the manhole cover water immersion monitoring terminal after installation and the state after removal directly correspond to the on and off of the device power supply, so that the device is in the power-on state after installation is completed, and in the power-off state after removal, avoiding the problem that traditional devices often forget to reset and turn on the power after installation and turn off the power after removal, so that the device can automatically reset and turn on the power after installation and automatically turn off the power after removal, reducing the operating steps, having a high degree of automation and effectively reducing the power consumption that may be caused when idle.
