Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of manhole covers, in particular to an integrated control board for controlling escape manhole covers. Background Art
[0002] The hydraulic intelligent manhole cover is an important device for the escape opening of the pipe gallery, responsible for functions such as personnel escape, access for maintenance personnel, and material entry and exit. The hydraulic intelligent manhole cover needs to use a wireless remote control switch and a button switch on-site, and also communicate with the background to realize the detection and control of the manhole cover by the background. The popularization and application of the hydraulic intelligent manhole cover help to improve the intelligent level of urban management, and at the same time can effectively enhance the safety and reliability of public facilities.
[0003] Currently, the control system of the escape manhole cover mainly consists of two major parts: a 24V high-power DC power supply and a control board based on a single-chip microcomputer. Among them, the 24V DC power supply is used to provide the electric energy required for the system operation. Especially when it is necessary to drive a micro hydraulic system to open or close the manhole cover, sufficient power supply must be ensured. The single-chip microcomputer control board is responsible for receiving external instructions, processing logical operations, and sending corresponding control signals to the hydraulic system to achieve precise control of the opening and closing of the manhole cover. When the escape manhole cover needs to be opened urgently, the system will instantaneously reach the maximum power demand, usually exceeding 350W. However, in the non-emergency state, that is, when the system is in the standby mode, even if no physical action is performed, the power consumption of the power supply is still as high as about 100W. This is mainly due to the control circuit and the basic energy consumption required to maintain the basic operation of the system. Whether in the standby or low-load state, the system always consumes relatively high energy. This not only causes great waste of energy but also increases the operation cost of the system. Especially in the case of no emergency for a long time, this inefficient energy use is particularly prominent, increasing the power use cost, and the continuous high power consumption may also have a negative impact on the life of the power supply module. The power supply in a high-load state for a long time is more likely to fail, thus reducing the reliability and stability of the entire system and increasing the maintenance cost.
[0004] Therefore, it is necessary to design an integrated control board for controlling escape manhole covers to solve the above problems. Summary of the Utility Model
[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose an integrated control board for controlling escape manhole covers.

This design greatly reduces energy waste, lowers the system operation cost, and also reduces the impact on the environment, embodying the concept of green energy conservation.
[0015] 2.

Detailed Embodiment
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0023] Embodiment 1
[0024] Referring to Figure 1 and Figure 4 , an integrated control board for escape manhole cover control, comprising a mounting plate 1. A control board 2 is provided on the side wall of the mounting plate 1. Four connecting rods 7 are fixed on the side wall of the control board 2. A slot 8 corresponding to the connecting rod 7 is provided on the mounting plate 1. A single-chip microcomputer module 5 for receiving control signals is installed on the control board 2. A switching power supply 3 for powering the device is also provided on the control board 2. The single-chip microcomputer module 5 includes a remote control part, a communication part and a sensor part. The sensor part is used to detect the opening and closing state of the manhole cover. Specifically, one end of the sensor is connected to the input port of the single-chip microcomputer module 5 for feeding back the current state of the manhole cover, and the other end is connected to the output end of the switching power supply 3. The switching power supply 3 has two output ends. One output end of the switching power supply 3 is configured as 5V / 20W, and the other output end is configured as 24V / 350W. And a rectifier bridge and a filter circuit are integrated inside the switching power supply 3, which can convert alternating current into direct current and can filter out the ripple in the direct current output to improve the power quality;
[0025] A control component for controlling the power supply is provided on the control board 2. The control component includes a miniature circuit breaker 4 installed on the control board 2. The input end of the miniature circuit breaker 4 is connected to an external AC power supply, and the output end of the miniature circuit breaker 4 is connected to the input end of the switching power supply 3. 220V alternating current is connected from the power grid and first passes through the miniature circuit breaker 4. The main function of the miniature circuit breaker 4 is to provide overload and short-circuit protection. Once the current in the circuit exceeds its rated value, the miniature circuit breaker 4 will automatically cut off the circuit to prevent safety accidents such as electrical fires. Select an appropriate rated current value for the miniature circuit breaker 4 to ensure that it can not only meet the maximum load requirements of the circuit but also respond quickly in case of overload or short circuit. One output end of the switching power supply 3 is connected to the power input end of the single-chip microcomputer module 5. Specifically, the output end of the switching power supply 3 configured as 5V / 20W is connected to the power input ends of the single-chip microcomputer module 5 and low-power components such as the indicator light on the manhole cover. A solid-state relay 6 is also provided on the control board 2. The other output end of the switching power supply 3 is connected to the control end of the solid-state relay 6. The output end of the switching power supply 3 configured as 24V / 350W is connected to the solid-state relay 6 through a wire. The selection of the solid-state relay 6 needs to meet the requirement of 24V DC control voltage and can withstand a load current of at least 350W. The output end of the single-chip microcomputer module 5 is connected to the control input end of the solid-state relay 6. The solid-state relay 6 is connected to the miniature hydraulic system on the manhole cover. In addition, an appropriate fuse or PTC self-resetting fuse is added to the circuit of the 24V DC output to the solid-state relay 6 to prevent overcurrent from damaging the circuit. Optionally, an emergency stop button is added and directly connected to the interrupt input of the single-chip microcomputer module 5 to cut off all power immediately in case of emergency.
[0026] Working principle: First, 220V AC power is connected from the power grid and undergoes primary protection through the miniature circuit breaker 4 to avoid the risks of overload or short circuit. Subsequently, the AC power is fed into the switching power supply 3, where the internal rectifier bridge and filter circuit convert it into stable and reliable DC power, generating outputs of 5V / 20W and 24V / 350W respectively. The 5V DC power mainly supplies power to low-power components such as the single-chip microcomputer module 5 and the indicator lights, while the 24V DC power is controlled by the solid-state relay 6 and is specifically prepared for driving the miniature hydraulic system. Under normal operating conditions, only the DC 5V power supply system in the system is working to keep the single-chip microcomputer module 5 operating. When the decision is made to start the hydraulic system, the single-chip microcomputer module 5 will send a control signal to the solid-state relay 6 to trigger the solid-state relay 6 to conduct, so that the 24V DC current flows to the hydraulic pump motor to drive the hydraulic system to operate and control the opening or closing of the manhole cover. When the system detects that the action of opening or closing the manhole cover is completed, the 24V DC voltage system is automatically turned off. This can not only provide sufficient power for the miniature hydraulic system well but also achieve the purpose of energy conservation when the system is in the standby state. In this way, the high-power DC power supply, since it is not in a long-term working state, is also very beneficial to the aging and lifespan of the system.
[0027] Embodiment 2
[0028] Embodiment 2 includes the content of Embodiment 1, and the technical features disclosed in Embodiment 1 are also applicable to this embodiment. The technical features already disclosed in Embodiment 1 will not be repeatedly described in the specification. The following further details the implementation manner of the integrated control board for escape manhole cover control with reference to the drawings.
[0029] Refer to Figure 2 and Figure 3 , a fixing component is provided between the mounting plate 1 and the control board 2. The fixing component includes a driving groove 9 opened on the side wall of the connecting rod 7. A plug 11 is slidably connected inside the driving groove 9. An inclined surface is provided on the side of the plug 11. A slot 10 corresponding to the plug 11 is opened inside the slot 8. An airbag one 12 is jointly fixed between the plug 11 and the driving groove 9. A connecting pipe one 13 is communicated with the airbag one 12. A cavity 14 is provided inside the control board 2. A rotating rod 17 is provided inside the cavity 14, and the top end of the rotating rod 17 extends to the outside of the control board 2. A sliding plate 16 is rotatably sleeved on the rotating rod 17. The sliding plate 16 is slidably connected with the inner side of the cavity 14, and the cross-section of the sliding plate 16 is in a rectangular structure. An airbag two 15 is jointly fixed between the sliding plate 16 and the inner top surface of the cavity 14, and all four connecting pipes one 13 are communicated with the airbag two 15;
[0030] The fixing component further includes a reinforcing member, which includes an airbag III 18 embedded in the side wall of the insertion block 11. A connecting pipe II 20 is communicated with the airbag III 18. A pressing rod 21 is fixed to the side wall at the bottom end of the rotating rod 17. An airbag IV 19 is fixed to the inner bottom surface of the cavity 14. The cross section of the pressing rod 21 is an inverted L-shaped structure, and the bottom end of the pressing rod 21 is a hemispherical structure, which reduces the wear between the pressing rod 21 and the airbag IV 19.
[0031] Working principle: The mounting plate 1 is mounted on the bottom of the manhole cover by means of screws or welding. When the control board 2 needs to be mounted on the mounting plate 1, the four connecting rods 7 are respectively inserted into the four slots 8. During the insertion process, under the action of the inclined surface of the insertion block 11, the mounting plate 1 presses the insertion block 11 so that the insertion block 11 can retract into the driving groove 9. At this time, the airbag I 12 is pressed by the insertion block 11, and the air inside it returns through the connecting pipe I 13 into the airbag II 15, causing the sliding plate 16 and the rotating rod 17 to move downward together. When the driving groove 9 corresponds to the insertion slot 10, under the elastic force of the airbag I 12 and the airbag II 15, the air in the airbag II 15 returns to the airbag I 12 again, and the airbag I 12 will push the insertion block 11 to slide so that a part of the insertion block 11 can be located in the insertion slot 10, thereby realizing the fixation between the connecting rod 7 and the mounting plate 1. On the contrary, when the staff needs to disassemble the control board 2 for maintenance, the rotating rod 17 is pushed, causing a negative pressure state to be generated in the airbag II 15 and sucking the air in the airbag I 12 into it. The airbag I 12 contracts, causing the insertion block 11 to retract into the driving groove 9, that is, realizing the separation between the connecting rod 7 and the mounting plate 1, realizing a fast and convenient disassembly and assembly operation, which improves the maintenance efficiency.
[0032] Further, during the above installation process, after the insertion block 11 moves into the insertion slot 10, the staff rotates the rotating rod 17 so that the pressing rod 21 can rotate and press the airbag IV 19. The air in the airbag IV 19 can enter the airbag III 18 through the connecting pipe II 20. The inflation and expansion of the airbag III 18 will fill the gaps between the insertion block 11 and the insertion slot 10 and the driving groove 9, which can improve the overall structural stability of the device and enhance the fixation of the control board 2.
[0033] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
