Description

Technical Field

[0001] The present invention relates to the technical field of sewer manhole covers, and in particular to a manhole cover with an anti-theft function. Background Art

[0002] With the acceleration of urbanization, underground pipeline facilities are becoming increasingly complex. As part of urban infrastructure, manhole covers not only bear the responsibility of protecting underground pipelines and ensuring the safety of pedestrians and vehicles, but also face the risk of theft. In order to improve the safety and management efficiency of manhole covers, more and more cities have begun to adopt anti-theft manhole covers with intelligent monitoring systems. These systems usually include sensors (such as displacement sensors, vibration sensors, etc.), communication modules and central processing units. By monitoring the status of manhole covers in real time, once an abnormal situation occurs (such as the manhole cover is illegally moved), the system can immediately send an alarm message to the management center so that timely response measures can be taken.

[0003] However, in actual applications, this type of smart anti-theft manhole cover has encountered a major technical bottleneck - the power supply problem. Currently, there are two common solutions: one is to directly connect to the mains, and the other is to use a built-in battery. Although this method of connecting to the mains can provide stable power support, it will encounter many challenges during the specific implementation process. For example, the underground environment is complex and changeable, and there may be problems such as moisture and corrosion, which increases the difficulty of wiring and electrical safety risks. In addition, additional protective measures such as waterproofing and moisture-proofing need to be considered. In comparison, the use of built-in batteries is more flexible and convenient. However, in the long run, this solution has obvious limitations. When the battery is used up, it is difficult to continue to supply power. The staff needs to find the manhole cover and remove the built-in battery for replacement. This is not only time-consuming and labor-intensive, but also extremely difficult to operate in some inaccessible locations. Summary of the Invention

[0004] In view of this, the present invention provides a manhole cover with an anti-theft function, which can solve the shortcomings of existing smart anti-theft manhole covers in dealing with power supply problems. When connecting to the mains, it increases the difficulty of wiring and electrical safety risks, while using built-in batteries has high maintenance costs and is difficult to operate.

[0005] The technical solution is: a manhole cover with an anti-theft function, including a manhole mounting frame and a manhole cover, the manhole cover is installed on the manhole mounting frame, and through holes are spaced apart on the top of the manhole cover, which are used for drainage. It also includes a locking mechanism, electrical equipment, a connecting bucket, a micro-hydro generator, a connecting line and a convergence mechanism. The manhole cover is provided with a locking mechanism, which is used to lock the manhole cover on the wellhead mounting frame. The manhole cover is provided with an electrical equipment at the bottom, which includes a terminal controller and a battery, which supplies power to the terminal controller. The electrical equipment is connected to a connecting bucket, and the bottom of the connecting bucket is connected to a micro-hydro generator, which is electrically connected to the battery of the electrical equipment through a connecting line, and the battery is used to store electricity. The manhole cover is provided with a convergence mechanism, which is used to converge water discharged from the through hole into the connecting bucket, and the connecting bucket collects the water and discharges it into the micro-hydro generator for kinetic energy generation, and then the micro-hydro generator transmits the current to the battery of the electrical equipment through the connecting line.

[0006] Furthermore, the locking mechanism includes an electric push rod and a card block. The electric push rod is symmetrically arranged on the manhole cover. The telescopic rod of the electric push rod is connected to the card block. The wellhead mounting frame is symmetrically provided with card slots. The card block is inserted into the card slot to lock the manhole cover on the wellhead mounting frame.

[0007] Furthermore, the gathering mechanism includes a supporting plate and a spring piece. The supporting plate is arranged at a circular interval and rotates at the bottom of the manhole cover. The supporting plate is used to gather the water discharged from the through hole into the connecting bucket. The spring piece is connected between the supporting plate and the manhole cover.

[0008] Furthermore, a magnetic plate is included, and the bottom of the supporting plate is connected to the magnetic plate. The magnetic plate is used to be adsorbed on the bottom of the connecting bucket to limit the supporting plate.

[0009] Furthermore, a sensor is included. The manhole cover is installed with a sensor for receiving signals from the outside of the manhole cover.

[0010] Furthermore, it also includes a filter screen, which is arranged at intervals on the connecting bucket and is used to filter water.

[0011] Furthermore, it also includes an annular slide plate, which is slidably provided on the outer wall of the connecting bucket and is used to scrape off the debris adhering to the filter screen.

[0012] Furthermore, it also includes a hollow plastic ring, which is connected to the outer side of the annular slide and is used to drive the annular slide to float.

[0013] The present invention has the following advantages: 1. The present invention adopts a micro-hydroelectric generator combined with the drainage function of the manhole cover, uses the water flowing through the manhole cover to generate electricity, and provides power support for electrical equipment. This design effectively solves the challenges faced by traditional smart anti-theft manhole covers in power supply, avoids the complex wiring and electrical safety risks brought by direct access to the mains, and overcomes the problem of inconvenience in replacing built-in batteries.

[0014] 2. The present invention adopts a locking mechanism including an electric push rod and a card block, so that the manhole cover can be firmly locked on the wellhead mounting frame, which greatly improves the safety of the manhole cover and prevents it from being illegally disassembled or stolen. At the same time, the coordinated use of sensors and electrical equipment allows workers to conveniently open and close the manhole cover by carrying a specific signal transmitting device, which improves work efficiency and enhances the intelligence level of the system.

[0015] 3. The present invention not only ensures the effective discharge of accumulated water, but also realizes the automatic cleaning of debris entering the system, prevents the occurrence of blockage, and ensures the normal operation of the micro-hydrogenerator through the design of the support plate and spring piece in the convergence mechanism, and the combined use of the filter screen, the annular slide plate and the hollow plastic ring.

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example: A manhole cover with anti-theft function, see Figure 1-Figure 7 As shown, it includes a wellhead mounting frame 1 and a manhole cover 2; the wellhead mounting frame 1 is used to be installed on the sewer wellhead; the manhole cover 2 is placed on the wellhead mounting frame 1, and through holes 3 are spaced apart on the top of the manhole cover 2, and the through holes 3 are used for drainage; It also includes a locking mechanism, electrical equipment 5, a connecting bucket 6, a micro hydroelectric generator 7, a connecting line 8 and a convergence mechanism; a locking mechanism is provided on the manhole cover 2, which is used to lock the manhole cover 2 on the wellhead mounting frame 1 to prevent the manhole cover 2 from being removed and stolen; an electrical device 5 is provided at the bottom of the manhole cover 2, which includes a terminal controller and a battery. The terminal controller includes sensors (such as displacement sensors, vibration sensors, etc.), a communication module and a central processing unit. By monitoring the status of the manhole cover in real time, the system can immediately respond to any abnormal situation (such as the manhole cover being illegally moved) An alarm message is sent to the management center so that timely response measures can be taken; the electrical equipment 5 is connected to a connecting bucket 6, which is made of iron; the bottom of the connecting bucket 6 is connected to a micro-hydro generator 7; the micro-hydro generator 7 is electrically connected to the battery of the electrical equipment 5 through a connecting line 8; a converging mechanism is provided on the manhole cover 2, which is used to gather water discharged from the through hole 3 into the connecting bucket 6, and the connecting bucket 6 collects the water and discharges it into the micro-hydro generator 7 for kinetic energy generation, and then the micro-hydro generator 7 transmits the current through the connecting line 8 to the battery in the electrical equipment 5 for storage.

[0029] See Figure 2 and Figure 3As shown, the locking mechanism includes an electric push rod 401 and a block 402; the electric push rod 401 is symmetrically arranged on the left and right sides of the inner side of the manhole cover 2, and the electric push rod 401 is electrically connected to the electrical equipment 5; the telescopic rod of the electric push rod 401 is connected to the block 402, and the block 402 slides through the side wall of the manhole cover 2; the upper side of the wellhead mounting frame 1 is symmetrically provided with a slot 403, and the slot 403 is adapted to the size of the block 402. By inserting the block 402 into the slot 403, the manhole cover 2 can be locked on the wellhead mounting frame 1.

[0030] See Figure 5-Figure 7 As shown, the converging mechanism includes a supporting plate 901 and a spring piece 902; the supporting plate 901 is rotatably arranged at a circular interval on the bottom of the manhole cover 2; the spring piece 902 is connected between the supporting plate 901 and the manhole cover 2, and the supporting plate 901 is used to support the water discharged from the through hole 3. If the pressure of the water on the supporting plate 901 is less than the elastic force of the spring piece 902, the supporting plate 901 will gather the water discharged from the through hole 3 into the connecting bucket 6. If the pressure of the water on the supporting plate 901 is greater than the elastic force of the spring piece 902, the supported water squeezes the supporting plate 901 to rotate open, so that the supported water is quickly discharged into the sewer for discharge.

[0031] When in use, first install the wellhead mounting frame 1 on the sewer wellhead, then place the manhole cover 2 on the wellhead mounting frame 1, and align the clamping block 402 on the manhole cover 2 with the clamping slot 403 on the wellhead mounting frame 1, and then remotely control the terminal controller in the electrical device 5 to control the telescopic rod of the electric push rod 401 to extend, so that the electric push rod 401 drives the clamping block 402 to move into the clamping slot 403, so that the clamping block 402 is clamped into the clamping slot 403, and then the manhole cover 2 is locked on the wellhead mounting frame 1, so that the manhole cover 2 can be prevented from being dismantled and stolen, so that the manhole cover 2 has a certain anti-theft function; if the manhole cover 2 is dismantled and stolen by someone using violence, The terminal controller in the electrical device 5 will monitor the status of the manhole cover 2 in real time. Once an abnormal situation occurs (such as the manhole cover 2 is illegally moved), the system will immediately send an alarm message to the management center so that timely response measures can be taken; when there is water above the manhole cover 2, the accumulated water will be discharged into the bottom of the manhole cover 2 through the through hole 3. When the accumulated water falls on the supporting plate 901, the accumulated water will accumulate on the supporting plate 901. If the pressure of the accumulated water on the supporting plate 901 is less than the elastic force of the shrapnel 902, the accumulated water on the supporting plate 901 will flow into the micro-hydro generator 7 through the connecting bucket 6, so that the micro-hydro generator 7 uses the kinetic energy of the accumulated water to generate electricity. The accumulated water behind the micro hydroelectric generator 7 will be discharged into the sewer. When the micro hydroelectric generator 7 generates kinetic energy, the micro hydroelectric generator 7 will transmit the current through the connecting line 8 to the battery in the electrical device 5 for storage, so as to power the terminal controller in the electrical device 5, and at the same time, the battery in the electrical device 5 will power the electric push rod 401; if the pressure of the accumulated water on the support plate 901 is greater than the elastic force of the spring 902, the accumulated water on the support plate 901 will squeeze the support plate 901 to rotate open, causing the spring 902 to deform, and then the accumulated water on the support plate 901 will be directly discharged into the sewer to prevent the accumulated water on the support plate 901 from Excessive water will cause untimely discharge. Later, when the pressure of the accumulated water on the supporting plate 901 is less than the elastic force of the spring 902, the spring 902 will return to its original state, and the spring 902 will drive the supporting plate 901 to reverse and reset; later, when the manhole cover 2 needs to be repaired, it is only necessary to remotely control the terminal controller in the electrical equipment 5 to control the telescopic rod of the electric push rod 401 to shorten, so that the electric push rod 401 drives the block 402 to move and reset, thereby making the block 402 leave the slot 403, and then loosen the manhole cover 2 from the wellhead mounting frame 1, and then the staff will take the manhole cover 2 out of the wellhead mounting frame 1 for maintenance, and repeat the above operations for subsequent installations.

[0032] See Figure 5 As shown, a magnetic plate 10 is also included; a magnetic plate 10 is connected to one side of the bottom of the supporting plate 901 close to the connecting bucket 6, and the magnetic plate 10 is used to be adsorbed on the bottom of the connecting bucket 6 to limit the supporting plate 901.

[0033] By setting up a magnetic plate 10 and using the magnetic plate 10 to be adsorbed on the bottom of the connecting bucket 6, the stability of the supporting plate 901 can be improved, so that the pressure of the accumulated water on the supporting plate 901 needs to be greater than the elastic force of the spring 902 and the magnetic force of the magnetic plate 10, the accumulated water can squeeze the supporting plate 901 to rotate open, and the supporting plate 901 drives the magnetic plate 10 to rotate, so that the magnetic plate 10 is separated from the bottom of the connecting bucket 6; thereafter, when the pressure of the accumulated water on the supporting plate 901 is less than the elastic force of the spring 902 and the magnetic force of the magnetic plate 10, the spring 902 will drive the supporting plate 901 to reverse and reset, and the supporting plate 901 drives the magnetic plate 10 to reverse and reset, so that the magnetic plate 10 contacts the bottom of the connecting bucket 6.

[0034] See Figure 2 and Figure 3 As shown, a sensor 11 is also included; the sensor 11 is installed on the manhole cover 2. When a machine that can send a signal is brought close to the sensor 11, the sensor 11 can receive the signal sent by the machine outside the manhole cover 2. The sensor 11 is electrically connected to the terminal controller in the electrical equipment 5.

[0035] By setting up the sensor 11, when the staff needs to repair the manhole cover 2, they can bring a machine that can send signals close to the sensor 11. When the signal sent by the machine is within the receiving range of the sensor 11, the sensor 11 will send a "successful reception" message to the terminal controller in the electrical device 5 after receiving the signal from the machine, and then the terminal controller in the electrical device 5 will control the telescopic rod of the electric push rod 401 to shorten, thereby loosening the manhole cover 2 from the wellhead mounting frame 1; after that, when the manhole cover 2 is repaired, when the staff moves away from the manhole cover 2, the signal sent by the machine will gradually leave the receiving range of the sensor 11. When the sensor 11 cannot receive the signal, the sensor 11 will send a "failed reception" message to the terminal controller in the electrical device 5, and then the terminal controller in the electrical device 5 will control the telescopic rod of the electric push rod 401 to extend, thereby locking the manhole cover 2 on the wellhead mounting frame 1. In this way, it is convenient for the staff to remove the manhole cover 2 for maintenance, and there is no need to remotely control the terminal controller in the electrical device 5 through the control center.

[0036] See Figure 8 and Figure 9 As shown, a filter screen 12 is also included; filter screens 12 are arranged at intervals on the connecting bucket 6, and the filter screens 12 are used to filter water.

[0037] By setting up the filter 12, when the support plate 901 gathers the accumulated water into the connecting bucket 6, the filter 12 will filter the accumulated water entering the connecting bucket 6, thereby blocking the debris in the accumulated water and blocking it on the outside of the filter 12, preventing the debris from entering the micro hydro generator 7 and causing blockage.

[0038] See Figure 9 and Figure 10 As shown, an annular slide 13 is also included; an annular slide 13 is slidably provided on the outer wall of the connecting bucket 6, and the annular slide 13 is used to scrape off the debris adhering to the filter screen 12.

[0039] See Figure 9 and Figure 10 As shown, a hollow plastic ring 14 is also included; a hollow plastic ring 14 is connected to the outside of the annular slide 13, and the hollow plastic ring 14 is made of a plastic material with a density less than that of water. The hollow plastic ring 14 is used to drive the annular slide 13 to float.

[0040] When water accumulates on the support plate 901, the water will drive the hollow plastic ring 14 to float, thereby driving the annular slide 13 to move upward; when the water accumulated on the support plate 901 is drained, the hollow plastic ring 14 and the annular slide 13 will naturally fall due to gravity, causing the annular slide 13 to scrape off the debris adhered to the outside of the filter screen 12, thereby preventing the debris from adhering to the filter screen 12 and causing blockage, and then automatically cleaning the debris adhered to the outside of the filter screen 12.

[0041] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
