Description

Technical Field

[0001] This utility model relates to the field of fire hydrant pressure detection technology, and in particular to a fire detection device. Background Art

[0002] Indoor fire hydrants are used to supply water to the fire scene from indoor pipe networks. They are fixed indoor fire protection facilities in factories, warehouses, high-rise buildings, public buildings, and ships. They are usually installed in fire hydrant boxes and used in conjunction with fire hoses and nozzles. Outdoor fire hydrants are water supply facilities installed on fire water supply networks outside buildings. They are mainly used by fire trucks to draw water from municipal water supply networks or outdoor fire water supply networks to extinguish fires. They can also be directly connected to hoses and nozzles to extinguish fires.

[0003] The existing announcement number is CN217645739U, entitled "A Fire Hydrant Water Pressure Testing Device for Fire Protection Facility Testing". This device works by placing a sealed cylinder inside the fire hydrant and connecting it to the hydrant. Then, the measuring cylinder moves along the inner side of the sealed cylinder, pushing it outwards to contact the inner side of the fire hydrant. This prevents water leakage during testing, thus avoiding inaccurate testing and inconvenient installation, and improves the efficiency of testing personnel.

[0004] However, when testing the aforementioned fire-fighting equipment, the on / off status of the warning light is used to determine the water pressure of the fire hydrant. But this type of fire hydrant water pressure testing device can only detect whether the water pressure meets the standard, and cannot display the specific water pressure value. This is not conducive to recording the water pressure of the fire hydrant later for adjustment. Utility Model Content

[0005] The purpose of this invention is to provide a fire detection device that aims to improve the aforementioned problems.

[0006] This utility model is implemented as follows:

[0007] A fire detection device includes a detection component and a support component. The detection component includes a water guide tube with an open end that is connected to and fixed to a fire hydrant. The other end of the water guide tube is vertically connected to and fixed to a piston cylinder. A pressure gauge is connected to and fixed on the outer circumferential surface of the water guide tube. A movable component is vertically slidably installed in the piston cylinder. A vertical plate is vertically fixed to the bottom of the outer circumferential surface of the piston cylinder. An insulating shell is vertically fixed to the bottom end of the vertical plate. Multiple conductive plates are horizontally fixed through the insulating shell along the vertical direction. A warning light is horizontally fixed to the outer end face of the conductive plates. The support component is vertically assembled below the water guide tube.

[0008] Furthermore, the movable component includes a piston plate, which is vertically slidably inserted into the piston cylinder, and a guide rod is vertically fixed on the bottom surface of the piston plate.

[0009] Furthermore, the guide rod slides vertically through and is inserted into the bottom surface of the piston cylinder, and a screw cylinder is vertically fixed on the bottom surface of the guide rod.

[0010] Furthermore, a spring is vertically sleeved on the outside of the guide rod, and the two ends of the spring are fixed to the top of the screw cylinder and the bottom surface of the piston cylinder, respectively.

[0011] Furthermore, a stud is threaded into the screw barrel, and a terminal block is vertically fixed on the bottom end face of the stud. A conductive terminal is horizontally fixed on the outer wall of the stud, and the conductive terminal is electrically connected to the conductive plate on the insulating shell.

[0012] Furthermore, the support includes a bracket, with rollers fixed on the bottom surface of the bracket, and a horizontal bracket installed above the bracket.

[0013] Furthermore, a sliding rod is vertically fixed on the bottom surface of the bracket, and the sliding rod is vertically slidably inserted into the bracket. A screw rod is vertically threaded through the middle of the top surface of the bracket, and the top end of the screw rod is rotatably connected to the bottom surface of the bracket.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, one end of the water guide tube is connected and fixed to the fire hydrant, and then the water guide tube is vertically supported by the support member. Then, the fire hydrant is opened and water is guided into the water guide tube. The pressure value of the water in the fire hydrant is displayed according to the reading of the pressure gauge. At the same time, the water pressure is introduced into the piston cylinder, and the water pressure squeezes the moving part to move vertically, lighting up the warning lights at different heights in sequence. This facilitates the recording of the water pressure of the fire hydrant and makes it convenient for later adjustments. Attached Figure Description

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a fire detection device includes a detection component 1 and a support component 2. The detection component 1 includes a water guide tube 11, one end of which is open and connected to a fire hydrant. The other end of the water guide tube 11 is vertically connected to and fixed to a piston cylinder 13, and a pressure gauge 12 is connected and fixed to the outer circumference of the water guide tube 11. A movable component 14 is vertically slidably installed in the piston cylinder 13, and a vertical plate 15 is vertically fixed to the bottom of the outer circumference of the piston cylinder 13. An insulating shell 16 is vertically fixed to the bottom end of the vertical plate 15, and a horizontally penetrating part is fixed to the insulating shell 16 along the vertical direction. Multiple conductive plates 17 are provided, with warning lights 18 horizontally fixed on the outer end face of each conductive plate 17. A support member 2 is vertically assembled below the water guide tube 11. During use, one end of the water guide tube 11 is connected and fixed to the fire hydrant. The support member 2 is then used to vertically support the water guide tube 11. The fire hydrant is then opened to guide water into the water guide tube 11. The pressure value of the water in the fire hydrant is displayed according to the reading of the pressure gauge 12. At the same time, the water pressure is introduced into the piston cylinder 13, and the water pressure squeezes the moving part 14 to move vertically, lighting up the warning lights 18 at different heights in sequence. This facilitates the recording of the water pressure of the fire hydrant and makes it convenient for later adjustments.

[0024] Please see Figure 3 and Figure 4 The movable component 14 includes a piston plate 141, which is vertically slidably inserted into the piston cylinder 13. A guide rod 142 is vertically fixed on the bottom surface of the piston plate 141. The guide rod 142 is vertically slidably inserted into the bottom surface of the piston cylinder 13. A screw cylinder 144 is vertically fixed on the bottom surface of the guide rod 142. A spring 143 is vertically sleeved on the outside of the guide rod 142. The two ends of the spring 143 are respectively fixed to the top end of the screw cylinder 144 and the bottom surface of the piston cylinder 13. A stud 145 is threaded into the screw cylinder 144. A terminal block 146 is vertically fixed on the bottom surface, and a conductive terminal 147 is horizontally fixed on the outer wall of the stud 145. The conductive terminal 147 is electrically connected to the conductive sheet 17 on the insulating shell 16. During use, the terminal block 146 is electrically connected to the power cable. When water pressure is introduced into the piston cylinder 13, the water pressure squeezes the piston plate 141 to move vertically. When the conductive terminal 147 on the stud 145 comes into contact with the conductive sheet 17 on the insulating shell 16, the power supply line of the warning light 18 is connected, causing the warning light 18 to light up to indicate the water level.

[0025] Please see Figure 5The support 2 includes a bracket 21, with rollers 25 fixed on the bottom surface of the bracket 21, and a bracket 22 horizontally arranged above the bracket 21. A sliding rod 23 is vertically fixed on the bottom surface of the bracket 22, and the sliding rod 23 is vertically slidably inserted into the bracket 21. A screw 24 is vertically threaded through the middle of the top surface of the bracket 21, and the top end of the screw 24 is rotatably connected to the bottom surface of the bracket 22. When rotating the screw 24 on the bracket 21, the bracket 22 is vertically pushed to slide vertically on the bracket 21, thereby lifting the water guide tube 11 upward.

[0026] Working principle: During use, one end of the water guide tube 11 is connected and fixed to the fire hydrant. Then, the water guide tube 11 is vertically supported by the support member 2. Then, the fire hydrant is opened and water is guided into the water guide tube 11. The pressure value of the water in the fire hydrant is displayed according to the reading of the pressure gauge 12. At the same time, the water pressure is introduced into the piston cylinder 13. The terminal 146 is electrically connected to the power cable. When the water pressure is introduced into the piston cylinder 13, the water pressure squeezes the piston plate 141 to move vertically. When the conductive terminal 147 on the stud 145 comes into contact with the conductive piece 17 on the insulating shell 16, the power supply line of the warning light 18 is connected, so that the warning light 18 lights up to indicate the water level. The warning lights 18 at different heights are lit in sequence.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
