Description

Technical Field

[0001] This invention relates to the field of fire hydrant technology, specifically to an intelligent transmission-type multi-purpose fire hydrant and its control system. Background Technology

[0002] Fire hydrants are water intake interfaces that connect to urban water supply systems. They are widely installed on roads, building exteriors, and underground spaces to provide high-pressure, high-flow-rate water for firefighting, pipeline testing, and maintenance. Common types include vertical hydrants, horizontal hydrants, high and low position hydrants, and indoor / intelligent hydrants. Key parameters include interface diameter, working pressure, corrosion resistance and protection level, as well as opening and closing methods and safety compliance requirements.

[0003] A smart transmission-type multi-purpose fire hydrant and its control system, disclosed in patent publication number CN111467723A, includes a fire hydrant base, a fire hydrant top seat mounted on the top of the base, a controller embedded in one end of the base, a GPRS transmitter embedded in one end of the base corresponding to the controller, and a placement base fixedly connected to the bottom of the base. This invention features a scientifically sound and reasonable structure, is safe and convenient to use, and allows for disassembly of the fire hydrant base and top seat via mounting bolts, mounting edges, fixing screws, positioning plates, and positioning grooves. This facilitates internal maintenance of the fire hydrant base and top seat, reducing the difficulty of fire hydrant maintenance. Furthermore, the inclusion of a connecting ring, filter grille, connecting screws, and collection ring plate prevents larger impurities in the water flow from entering the fire hydrant pipe, thus avoiding blockages and affecting water flow.

[0004] During peak and off-peak load periods in urban high-density pipe networks, fire hydrants may lack adaptive hydraulic management capabilities, making it difficult to quickly suppress peak pressure surges in the pipe network. This drawback is particularly pronounced when there is massive concurrent water usage or simultaneous activation of fire hydrants, potentially causing instantaneous pressure to exceed safe limits, affecting the normal operation of the pipe network structure and the efficiency of fire hydrant use. In complex pipe networks or under dynamic fire extinguishing requirements, if the adaptive capability to pressure and flow is limited, pressure fluctuations, insufficient output, or overshoot may easily occur, which could lead to decreased fire extinguishing efficiency, increased difficulty in on-site control, and increased risk of subsequent pipe network damage. Therefore, this invention is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent transmission-type multi-purpose fire hydrant and its control system to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent transmission-type multi-purpose fire hydrant, comprising a main body and a low-pressure liquid inlet mechanism and a high-pressure buffer mechanism installed inside the main body. A top cover and a mounting plate are respectively installed on the top and bottom of the main body. An opening and closing mechanism for actively controlling liquid inlet is installed inside the top cover and the main body. The low-pressure liquid inlet mechanism and the high-pressure buffer mechanism are mounted on the opening and closing mechanism via the mounting mechanism. The opening and closing mechanism includes a protective cover installed on the outer wall of the top of the top cover. A rotatable vertical rod is embedded in the top cover. A fixing ring is installed at the bottom of the inner wall of the main body. A valve plate connected to the bottom outer wall of the fixing ring is installed on the vertical rod. The valve plate has a top... A sealing ring is installed on the outer wall of the main body, and a sealing groove corresponding to the sealing ring is installed on the bottom outer wall of the fixing ring. A fixing plate is installed on the inner wall of the main body at the top of the drain pipe. A threaded structure is installed on the middle outer wall of the vertical rod, and the fixing plate is sleeved on the threaded structure of the vertical rod. The low-pressure liquid inlet mechanism includes a first liquid inlet component and a pressure boosting component. The first liquid inlet component includes several low-pressure processing pipes installed on the valve plate through an installation mechanism. The pressure boosting component is installed in the low-pressure processing pipes. The high-pressure buffer mechanism includes a second liquid inlet component and a pressure reducing component. The second liquid inlet component includes several high-pressure processing pipes installed on the valve plate through an installation mechanism. The pressure reducing component is installed in the high-pressure processing pipes.

[0007] Furthermore, a filtration mechanism is installed inside the main body at the bottom of the drain pipe. The filtration mechanism includes a bottom plate fixedly connected to the inner wall of the main body, a rotatable top plate installed on the bottom plate, the bottom plate and the top plate being sleeved on the outer wall of the vertical rod, and several fan-shaped grooves are opened on the outer walls of the bottom plate and the top plate. Filter plates are installed in the fan-shaped grooves on the outer walls at both ends of the bottom plate and the top plate.

[0008] Furthermore, an adjustment mechanism is installed on the outer wall of the main body. The adjustment mechanism includes a semi-annular groove formed on the outer wall of the main body, an adjustment plate located in the semi-annular groove is installed on the outer wall of the top plate, and annular airbags are embedded in the top and bottom of the outer wall of the top plate. An air box connected to the annular airbags is installed on the outer wall of the main body.

[0009] Furthermore, a maintenance mechanism is installed on the outer wall of the main body. The maintenance mechanism includes a side groove formed on the outer wall of the main body, a side plate installed in the side groove, and ear plates installed at both ends of the outer walls of the main body and the side plates. The ear plates are provided with mounting grooves.

[0010] Furthermore, the booster assembly includes lugs installed at both ends of the inner wall of the low-pressure processing pipe, a vertical column installed between the two lugs, a vertical groove opened on the outer wall of the vertical column, a round block sleeved on the outer wall of the vertical column, and a telescopic assembly in which a piston rod is connected to the round block is embedded in the vertical column.

[0011] Furthermore, the voltage reduction assembly includes several side blocks installed on the inner wall of the high-pressure processing pipe, a top block inserted into the high-pressure processing pipe, a buffer spring installed between the side blocks and the top block, a first circular plate installed at the bottom of the inner wall of the high-pressure processing pipe, a connecting column driven by a drive motor installed on the bottom outer wall of the first circular plate, a second circular plate installed on the outer wall of the connecting column, and several circular grooves opened on both the first and second circular plates.

[0012] Furthermore, the installation mechanism includes several installation positions on the valve plate, where both the low-pressure treatment pipe and the high-pressure treatment pipe are located. An annular plate is installed on the top outer wall of both the low-pressure and high-pressure treatment pipes. Connecting rods are installed at both ends of the bottom outer wall of the annular plate, and protrusions are installed on the bottom outer wall of the connecting rods. An annular groove is formed on the top outer wall of the valve plate outside the installation positions. Slots corresponding to the protrusions are formed on the inner walls at both ends of the annular groove, and a bottom groove corresponding to the rotation trajectory of the protrusions is formed on the bottom inner wall of the annular groove. The low-pressure treatment pipe and the high-pressure treatment pipe are installed in the installation positions by inserting the protrusions into the slots and rotating them.

[0013] A smart transmission-type multi-purpose fire hydrant control system is provided, which uses the aforementioned smart transmission-type multi-purpose fire hydrant. The control system includes: a preset water pressure threshold; monitoring the opening and closing status of the protective cover; when the protective cover is open, acquiring the real-time water pressure; determining the relationship between the water pressure threshold and the real-time water pressure; when the real-time water pressure is greater than the water pressure threshold, using a high-pressure buffer mechanism for liquid inlet; when the real-time water pressure is less than the water pressure threshold, using a low-pressure liquid inlet mechanism for liquid inlet; and when the real-time water pressure is within the water pressure threshold, using an opening and closing mechanism for liquid inlet.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This intelligent transmission-type multi-purpose fire hydrant and its control system can filter water through a filtration mechanism to prevent impurities from clogging the pipes and hindering firefighting operations. A low-pressure inlet mechanism pressurizes the water supply when the pressure is low, delivering water to the main body. A high-pressure buffer mechanism reduces pressure when the supply pressure is excessive, suppressing pressure spikes in the pipeline network and lowering the probability of decreased firefighting efficiency, increased on-site control difficulty, and increased risk of subsequent pipeline damage. Furthermore, the low-pressure inlet mechanism, high-pressure buffer mechanism, and opening / closing mechanism are all independent structures, allowing for individual or simultaneous operation to adapt to different water pressure conditions and usage requirements.

[0016] Meanwhile, the established maintenance mechanism facilitates routine maintenance of the filtration mechanism, low-pressure inlet mechanism, and high-pressure buffer mechanism, reducing maintenance difficulty and extending their service life. When filtration is required, the positions of the bottom and top plates are adjusted using the adjustment mechanism until the filter plates on the top plate cover the fan-shaped grooves on the bottom plate, or vice versa. When there is a high water demand, the filtration effect can be disabled by adjusting the filter plates on the bottom and top plates to be connected. After the top plate position is adjusted, the air pump is activated to fill the annular airbag until it is in full contact with the inner wall of the main body, thereby improving the sealing performance.

[0017] Meanwhile, the circular groove can filter out impurities, preventing them from affecting the operation of components in the high-pressure treatment tube. The installation and maintenance mechanisms further facilitate maintenance of the low-pressure inlet and high-pressure buffer mechanisms. When disassembling the low-pressure and high-pressure treatment tubes, simply rotate them to remove them from their mounting positions. Magnetic structures can also be added to the final resting positions of the low-pressure and high-pressure treatment tubes in the bottom groove to improve their fixation during installation.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] During the use of fire hydrants, routine maintenance is required. Key aspects of routine maintenance include visual inspection, functional testing, antifreeze and anti-corrosion treatment, and comprehensive record-keeping. In smart fire protection, fire hydrants can be remotely monitored, analyzed, and controlled via the Internet of Things, improving emergency response and maintenance efficiency. Fire hydrants are essential for firefighting operations. The fire hydrant provided by this invention is specifically designed for firefighting operations that require power to cope with excessive or insufficient water pressure. Before using this fire hydrant for firefighting operations, the components requiring power should be powered and regularly maintained to ensure the normal operation of the fire hydrant. Example 1:

[0029] like Figures 1-8As shown, the present invention provides a technical solution: an intelligent transmission type multi-purpose fire hydrant, including a main body 1 and a low-pressure liquid inlet mechanism 9 and a high-pressure buffer mechanism 10 installed inside the main body 1. A top cover 2 and a mounting plate 7 are respectively installed on the top and bottom of the main body 1. An opening and closing mechanism 3 for actively controlling the liquid inlet is installed inside the top cover 2 and the main body 1. The low-pressure liquid inlet mechanism 9 and the high-pressure buffer mechanism 10 are mounted on the opening and closing mechanism 3 through the mounting mechanism 13. The opening and closing mechanism 3 includes a protective cover 301 installed on the outer wall of the top of the top cover 2. A rotatable vertical rod 302 is embedded in the top cover 2. A fixing ring 304 is installed at the bottom of the inner wall of the main body 1. A valve plate 305 connected to the bottom outer wall of the fixing ring 304 is installed on the vertical rod 302. A sealing ring 12 is installed on the top outer wall of the valve plate 305. A sealing groove corresponding to the sealing ring 12 is installed on the bottom outer wall of the fixing ring 304. A fixing plate 303 is installed on the inner wall of the main body 1 at the top of the drain pipe. A threaded structure is installed on the middle outer wall of the vertical rod 302. The fixing plate 303 is sleeved on the threaded structure of the vertical rod 302. Several drain pipes are installed on the outer wall of the main body 1. The low-pressure liquid inlet mechanism 9 includes a first liquid inlet component and a pressure boosting component. The first liquid inlet component includes several low-pressure processing pipes 901 installed on the valve plate 305 through the mounting mechanism 13. The pressure boosting component is installed in the low-pressure processing pipes 901. The high-pressure buffer mechanism 10 includes a second liquid inlet component and a pressure reducing component. The second liquid inlet component includes several high-pressure processing pipes 1001 installed on the valve plate 305 through the mounting mechanism 13. The pressure reducing component is installed in the high-pressure processing pipes 1001.

[0030] It should be noted that the low-pressure inlet mechanism 9 and the high-pressure buffer mechanism 10 are quickly assembled and disassembled on the opening and closing mechanism 3 via the installation mechanism 13. The low-pressure inlet mechanism 9 and the high-pressure buffer mechanism 10, in conjunction with the opening and closing mechanism 3, handle water pressure over-rush, insufficient water pressure, and normal water pressure during use. When this fire hydrant is needed, it must first be installed at the designated location and connected to the main water supply pipe via the mounting plate 7, providing necessary adjustments for hydrant operation. The opening and closing mechanism 3 allows for active control of water intake. Specifically, by connecting the fire pipe requiring water to the drain pipe, and then actively introducing water via the opening and closing mechanism 3, firefighting operations can be carried out. Before the water enters the drain pipe, the filter mechanism 8 filters the water to prevent impurities from clogging the pipe and hindering firefighting operations. The low-pressure inlet mechanism 9 pressurizes the water supply when the water pressure is low, delivering water to the main body 1. The high-pressure buffer mechanism 10 controls the water supply when the water pressure is excessive. The buffer and pressure reduction operation helps to suppress the impact of peak pressure in the pipeline network, reducing the probability of decreased fire extinguishing efficiency, increased on-site control difficulty, and increased risk of subsequent pipeline damage. The low-pressure liquid inlet mechanism 9, the high-pressure buffer mechanism 10, and the opening and closing mechanism 3 are all independent structures that can operate individually or simultaneously to adapt to different water pressure conditions and usage requirements. Liquid is introduced through the first and second liquid inlet components. When the opening and closing mechanism 3 is needed, the protective cover 301 is removed, and the vertical rod 302 is rotated. Through the threaded structure and the action of the fixing plate 303, the gap between the valve plate 305 and the fixing ring 304 can be adjusted, thereby adjusting the water inlet space. The sealing ring 12 and the sealing groove can improve the overall sealing performance when water inlet is stopped. The vertical rod 302 can also be designed to be electrically driven, specifically a motor driven, according to actual usage requirements. Pressure sensors and temperature sensors can be installed inside the main body 1 to monitor the water status in the main body 1 in real time and transmit the information to the staff so that the staff can remotely understand the working environment of the fire hydrant. Example 2:

[0031] like Figure 4 As shown, a filter mechanism 8 is installed inside the main body 1 at the bottom of the drain pipe. The filter mechanism 8 includes a bottom plate 802 fixedly connected to the inner wall of the main body 1, a rotatable top plate 801 installed on the bottom plate 802, and the bottom plate 802 and the top plate 801 are sleeved on the outer wall of the vertical rod 302. Several fan-shaped grooves 803 are opened on the outer walls of the bottom plate 802 and the top plate 801. Filter plates 804 are installed in the fan-shaped grooves 803 on the outer walls at both ends of the bottom plate 802 and the top plate 801.

[0032] It should be noted that when the filter mechanism 8 is used for filtration, the positions of the bottom plate 802 and the top plate 801 are adjusted by the adjustment mechanism 4 until the filter plate 804 on the top plate 801 covers the fan-shaped groove 803 on the bottom plate 802. Conversely, when there is a high water demand, the filtration effect can also be eliminated by adjusting the filter plate 804 on the bottom plate 802 and the filter plate 804 on the top plate 801 to be connected by the adjustment mechanism 4. Example 3:

[0033] like Figure 3 and Figure 4 As shown, an adjustment mechanism 4 for adjusting whether the filter mechanism 8 is filtering is installed on the outer wall of the main body 1. The adjustment mechanism 4 includes a semi-annular groove 401 opened on the outer wall of the main body 1. An adjustment plate 402 located in the semi-annular groove 401 is installed on the outer wall of the top plate 801. Annular airbags 11 are embedded in the top and bottom of the outer wall of the top plate 801. An air box 6 connected to the annular airbag 11 is installed on the outer wall of the main body 1. The maintenance mechanism 5 includes a side groove opened on the outer wall of the main body 1. A side plate 501 is installed in the side groove. Ear plates 502 are installed at both ends of the outer walls of the main body 1 and the side plate 501. The ear plates 502 have mounting grooves.

[0034] It should be noted that when the adjustment mechanism 4 is needed, the position of the filter plate 804 on the top plate 801 can be adjusted by moving the adjustment plate 402 in a circular motion, thereby adapting to different usage needs. The air box 6 is connected to an external component with a pumping function, specifically a pumping air pump. After the position of the top plate 801 is adjusted by starting the pumping air pump, the annular air bag 11 is filled with air until it is in full contact with the inner wall of the main body 1, thereby improving the sealing performance. Conversely, adjusting the position of the top plate 801 can improve the sealing performance. Bolts can be installed in the mounting groove on the ear plate 502 to install the side plate 501 on the side groove of the main body 1. Specifically, the contact part between the side plate 501 and the side groove needs to be filled with a sealing gasket to improve the sealing performance. The detachable side plate 501 facilitates the corresponding treatment of the filter mechanism 8, the low-pressure liquid inlet mechanism 9, and the high-pressure buffer mechanism 10 during maintenance. Example 4:

[0035] like Figure 3 As shown, a maintenance mechanism 5 is installed on the outer wall of the main body 1. The maintenance mechanism 5 includes a side groove opened on the outer wall of the main body 1, a side plate 501 installed in the side groove, and ear plates 502 installed at both ends of the outer walls of the main body 1 and the side block 1004. The ear plates 502 are provided with mounting grooves.

[0036] It should be noted that the maintenance mechanism 5 facilitates routine maintenance of the filter mechanism 8, low-pressure liquid inlet mechanism 9, and high-pressure buffer mechanism 10 by staff, reducing maintenance difficulty and extending their service life. The detachable side plate 501 facilitates appropriate maintenance of the filter mechanism 8, low-pressure liquid inlet mechanism 9, and high-pressure buffer mechanism 10.

[0037] like Figure 7 As shown, the low-pressure liquid inlet mechanism 9 includes several low-pressure processing pipes 901 mounted on the valve plate 305 via the mounting mechanism 13. Both ends of the inner wall of the low-pressure processing pipe 901 are equipped with lugs 902. A vertical column 903 is installed between two lugs 902. A vertical groove is opened on the outer wall of the vertical column 903. A round block 904 is sleeved on the outer wall of the vertical column 903. A telescopic assembly that connects the piston rod and the round block 904 is embedded in the vertical column 903.

[0038] It should be noted that when using the low-pressure liquid inlet mechanism 9, the telescopic component drives the circular block 904 to move up and down on the vertical column 903, which can simulate the effect of drilling a water well, providing an active water supply effect and improving the efficiency of water intake when the water pressure is low. When the circular block 904 moves upward (water intake stage): the central hole opens, a negative pressure is formed below, and the water flows through the hole into the upper cavity of the circular block 904 (similar to syringe suction). The low-pressure treatment pipe 901 located at the bottom of the vertical column 903 can be made of a flexible hose for easy maintenance. Specifically, a sealing ring can be added to the contact part between the circular block 904 and the low-pressure treatment pipe 901 to improve the sealing performance and enhance the water supply effect.

[0039] like Figure 8 As shown, the high-pressure buffer mechanism 10 includes several high-pressure processing tubes 1001 mounted on the valve plate 305 via the mounting mechanism 13. Several side blocks 1004 are mounted on the inner wall of the high-pressure processing tubes 1001. A top block 1002 is inserted into the high-pressure processing tubes 1001. Buffer springs 1003 are installed between the side blocks 1004 and the top block 1002. A first circular plate 1005 is mounted at the bottom of the inner wall of the high-pressure processing tubes 1001. A connecting column 1007 driven by a drive motor is mounted on the bottom outer wall of the first circular plate 1005. A second circular plate 1006 is mounted on the outer wall of the connecting column 1007. Several circular grooves are opened on both the first circular plate 1005 and the second circular plate 1006.

[0040] It should be noted that when using the high-pressure buffer mechanism 10, the starting of the drive motor drives the connecting column 1007 to rotate, so that the circular grooves on the first circular plate 1005 and the second circular plate 1006 are connected. At this time, water will enter the interior of the main body 1 through the high-pressure treatment pipe 1001. The buffer spring 1003 set inside the high-pressure treatment pipe 1001, in conjunction with the top block 1002, can buffer the water pressure surge, reduce the damage to the interior of the main body 1 and the fire pipe, and suppress the peak pressure impact of the pipeline network. At the same time, the circular groove can also filter impurities, preventing impurities from affecting the operation of the components in the high-pressure treatment pipe 1001. In addition, in order to improve the stability of the components, the components that come into direct contact with water need to be rust-proofed, and the electronic components need to be sealed. For example, the drive motor is driven by a sealed bearing, and the telescopic component is externally fitted with an airbag, such as an airbag made of highly elastic rubber. The specific treatment depends on the actual use.

[0041] like Figure 6 and Figure 7 As shown, the installation mechanism 13 includes several installation positions on the valve plate 305. The low-pressure treatment pipe 901 and the high-pressure treatment pipe 1001 are both located in the installation positions. An annular plate 1303 is installed on the top outer wall of both the low-pressure treatment pipe 901 and the high-pressure treatment pipe 1001. Connecting rods 1305 are installed at both ends of the bottom outer wall of the annular plate 1303. A protrusion 1304 is installed on the bottom outer wall of the connecting rod 1305. An annular groove 1301 is opened on the top outer wall of the valve plate 305 outside the installation position. The inner walls at both ends of the annular groove 1301 are provided with slots 1302 corresponding to the protrusions 1304. The bottom inner wall of the annular groove 1301 is provided with a bottom groove corresponding to the rotation trajectory of the protrusions 1304. The low-pressure treatment pipe 901 and the high-pressure treatment pipe 1001 are installed in the installation position by inserting the protrusions 1304 into the slots 1302 and rotating them.

[0042] It should be noted that by using the installation mechanism 13 in conjunction with the maintenance mechanism 5, it is easier for staff to maintain the low-pressure liquid inlet mechanism 9 and the high-pressure buffer mechanism 10. When disassembling the low-pressure treatment tube 901 and the high-pressure treatment tube 1001, they can be removed from the installation position simply by rotating the low-pressure treatment tube 901 and the high-pressure treatment tube 1001. Specifically, a magnetic structure can be added to the final stopping position of the low-pressure treatment tube 901 and the high-pressure treatment tube 1001 in the bottom tank to improve the fixing effect of the low-pressure treatment tube 901 and the high-pressure treatment tube 1001 during installation.

[0043] A smart transmission-type multi-purpose fire hydrant control system includes: a preset water pressure threshold; monitoring the opening and closing status of a protective cover 301; when the protective cover 301 is open, acquiring the real-time water pressure; determining the relationship between the water pressure threshold and the real-time water pressure; when the real-time water pressure is greater than the water pressure threshold, using a high-pressure buffer mechanism 10 to allow liquid inlet; when the real-time water pressure is less than the water pressure threshold, using a low-pressure inlet mechanism 9 to allow liquid inlet; and when the real-time water pressure is within the water pressure threshold range, allowing liquid inlet through an opening and closing mechanism 3.

[0044] It is important to note that the water pressure threshold is a range value, which is set by the staff according to the actual situation. The process of monitoring the opening and closing status of the protective cover 301 determines whether the fire hydrant needs to be used. When the protective cover 301 is removed, it is determined that the fire hydrant needs to be used. By obtaining the real-time water pressure supplied to the water supply pipeline connected to the mounting plate 7, it is determined which mechanism to use for water intake. When the real-time water pressure is greater than the water pressure threshold, the high-pressure buffer mechanism 10 is used for liquid intake. When the real-time water pressure is less than the water pressure threshold, the low-pressure liquid intake mechanism 9 is used for liquid intake. When the real-time water pressure is within the water pressure threshold, liquid intake is carried out through the opening and closing mechanism 3. By determining the water intake method through real-time response, the water supply pressure can be increased when the water supply pressure is low, and buffered and depressurized when the water supply pressure is too high, thus suppressing the peak pressure impact of the pipeline network and reducing the decrease in fire extinguishing efficiency due to insufficient water supply pressure.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended embodiments and their equivalents.
