Description

Technical Field

[0001] The utility model belongs to the technical field of fire-fighting equipment, and specifically relates to a fire hydrant water pressure detection device for building fire-fighting facilities detection. Background Art

[0002] A fire hydrant is a fixed fire-fighting facility. Its main functions are to control combustibles, isolate combustion-supporting substances, and eliminate ignition sources. It is mainly used for fire trucks to draw water from the municipal water supply network or the outdoor fire-fighting water supply network to implement fire extinguishing. It can be connected to a water hose and a water gun to discharge water for fire extinguishing. Since a fire hydrant can only be used when needed for fire extinguishing and is usually idle at ordinary times, in order to ensure whether the water supply pressure of the fire hydrant meets the standard, a special detection device is required for water pressure detection.

[0003] For the existing fire hydrant water pressure detection device for building fire-fighting facilities detection, when it is detecting, due to the large impact force of water at the moment when the water gate is opened, it is easy to cause some impacts on the inside of the detection device, and it is easy to damage the internal components after a long time.

[0004] Moreover, since the fire hydrant is in an idle state for a long time, it is easy to rust inside, thus generating iron slag. When the detection device is detecting, the water carries the iron slag into the inside of the detection device, and it is impossible to collect the iron slag, which is easy to pollute the inside of the detection device, and will pollute the surrounding environment when discharged with the water flow. Content of the Utility Model

[0005] The purpose of the utility model is to solve the above problems. The utility model provides a fire hydrant water pressure detection device for building fire-fighting facilities detection, which has the advantages of buffering and removing iron slag.

[0006] To achieve the above object, the present utility model provides the following technical solutions: a fire hydrant water pressure detection device for building fire protection facilities detection, including a connecting pipe. In the middle of the outer end of the right side of the connecting pipe, an activity groove is opened. Along the circumference, a plurality of first springs are equidistantly installed inside the activity groove. The left end of the first spring is fixedly connected to a connecting plate located inside the activity groove. The right side of the connecting plate is fixedly connected to a detection pipe. At the top of the right end of the detection pipe, a water pressure detector is fixedly installed. The right side of the detection pipe is fixedly connected to a water storage tank. Inside the right end of the water storage tank, a plug rod is fixedly installed. The inside of the right end of the detection pipe is movably connected to a top plate. The right side of the top plate is fixedly connected to a cavity cylinder. In the middle of the right side of the top plate, a second spring located inside the cavity cylinder is fixedly connected. On the front and rear sides of the right end of the cavity cylinder, limiting plates are fixedly connected. First, the connector can be connected to the connection port on the fire hydrant. Then, the water gate of the fire hydrant is opened. The impact force generated by the instantaneously ejected water will push the detection pipe to move to the right. With the cooperation of a circle of elastic first springs and the connecting plate, a simple buffering effect can be achieved to weaken the impact force. At the same time, the water pressure detector can detect the water pressure of the fire hydrant and display it in the form of a numerical value on the display panel. At the same time, the water flow will push the top plate and the cavity cylinder to move to the right, thus cooperating with the plug rod to compress the second spring. The elastic second spring, in the form of pushing the top plate, can prevent the water flow from impacting the inside of the water storage tank. When the top plate enters the inside of the water storage tank, the water flow will overflow from the connection and enter the inside of the water storage tank for storage.

[0007] As a preferred technical solution of the present utility model, a connector is fixedly installed on the left side of the connecting pipe. Inside the right end of the water storage tank, a sealing cover plate is movably connected. The left end of the sealing cover plate is movably clamped with a connection seat. Along the circumference, four iron absorbing stone plates are equidistantly fixedly connected to the left side of the connection seat. The instantaneously ejected water flow will carry a large amount of iron slag. By pushing the top plate to move to the right and then entering the inside of the water storage tank from the connection, the iron absorbing stone plates can adsorb the iron slag mixed in the water. After the water pressure detection is completed and the water gate is closed, the elastic second spring will push the top plate to reset, thus blocking the detection pipe and preventing the water containing iron slag from flowing back. After being adsorbed by the iron absorbing stone plates, a large amount of iron slag mixed in the water can be adsorbed. Then, the sealing cover plate is rotated. Due to the existence of threads, the sealing cover plate can be removed and the connection seat and the iron absorbing stone plates can be removed from the inside of the water storage tank. The water without iron slag will be directly discharged, and then the iron slag adsorbed on the iron absorbing stone plates can be disposed of.

[0008] As a preferred technical solution of the present utility model, a display panel is fixedly installed on the top of the right end of the water storage tank. The plug rod is installed in the middle of the inside of the right end of the water storage tank through four fixing plates. The water pressure detector can detect the water pressure of the fire hydrant and display it in the form of a numerical value on the display panel, which is convenient for viewing. The plug rod can be limited and fixed in the middle through the four fixing plates.

[0009] As a preferred technical solution of the present utility model, limiting sliding grooves are provided on the front and rear inner walls at the left end of the water storage tank. The inner diameter value of the connecting pipe is greater than that of the detection pipe, and the inner diameter value of the detection pipe is smaller than that of the water storage tank. Due to the existence of the limiting sliding grooves and the limiting plates, the cavity cylinder can be ensured to be more stable during lateral movement; the water flow ejected instantaneously will push the detection pipe to move rightward, and the elastic first spring cooperates with the connecting plate to pull the detection pipe, which can provide a good buffering effect to weaken the impact force.

[0010] As a preferred technical solution of the present utility model, threads are engraved on the outer surface of the inner end of the sealing cover plate and the inner wall of the right end of the water storage tank. The installation position of each magnetic iron plate is located between every two fixing plates. Due to the existence of the threads, the sealing cover plate can be rotated to install and disassemble with the water storage tank. The magnetic iron plates are equidistantly distributed, which is convenient for adsorbing iron slag in water to the greatest extent.

[0011] As a preferred technical solution of the present utility model, lifting handles are fixedly installed on the left side of the upper end of the water storage tank and the middle of the right side of the sealing cover plate. The inner diameter value of the left end of the insertion rod is adapted to the inner diameter value inside the cavity cylinder. The whole device can be conveniently carried through the lifting handle, and the installation and disassembly of the sealing cover plate are also convenient; the insertion rod can well squeeze the second spring inside the cavity cylinder.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The present utility model realizes the advantage of buffering through the cooperation of structures such as the detection pipe, the first spring, and the connecting plate. First, the connection head can be connected to the connection port on the fire hydrant, and then the water gate of the fire hydrant is opened. The impact force generated by the instantaneously ejected water will push the detection pipe to move rightward. Under the cooperation of a circle of elastic first springs and the connecting plate, a simple buffering effect to weaken the impact force can be achieved. At the same time, the water pressure detector can detect the water pressure of the fire hydrant and display it in numerical form on the display panel; at the same time, the water flow will push the top plate and the cavity cylinder to move rightward, thereby cooperating with the insertion rod to squeeze the second spring. The elastic second spring can prevent the water flow from impacting the inside of the water storage tank in the form of pushing the top plate. When the top plate enters the inside of the water storage tank, the water flow will overflow from the connection and enter the inside of the water storage tank for storage, so that the purpose of buffering can be achieved.

[0014] 2. The utility model realizes the advantage of removing iron slag through the cooperation of structures such as the top plate, the iron-absorbing stone plate and the connecting seat. The water flow ejected instantaneously will carry a large amount of iron slag. By pushing the top plate to move to the right and then entering the interior of the water storage tank from the connection, the iron-absorbing stone plate can adsorb the iron slag mixed in the water. After the water pressure is detected, the water gate is closed, and the elastic second spring will push the top plate to reset, thus blocking the detection pipe and preventing the water containing iron slag from flowing back. Through the adsorption of the iron-absorbing stone plate, a large amount of iron slag mixed in the water can be adsorbed. Then rotate the sealing cover plate. Due to the existence of the thread, the sealing cover plate can be removed and the connecting seat and the iron-absorbing stone plate can be removed from the interior of the water storage tank. The water from which the iron slag has been removed will be directly discharged, and then the iron slag adsorbed on the iron-absorbing stone plate can be disposed of. In this way, the purpose of removing iron slag can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

On the front and rear sides of the right end of the cavity cylinder 11, limiting plates 16 are fixedly connected. First of all, the connector 2 can be connected to the connection port on the fire hydrant. Then, open the sluice of the fire hydrant. The impact force generated by the instantaneously ejected water will push the detection pipe 3 to move to the right. With the cooperation of the first spring 8 with elasticity and the connecting plate 9, a simple buffering effect can be achieved to weaken the impact force. At the same time, the water pressure detector 4 can detect the water pressure of the fire hydrant and display it in the form of a numerical value on the display panel. At the same time, the water flow will push the top plate 10 and the cavity cylinder 11 to move to the right, so as to cooperate with the plug rod 13 to squeeze the second spring 12. The elastic second spring 12 can prevent the water flow from impacting the inside of the water storage tank 5 in the form of pushing the top plate 10. When the top plate 10 enters the inside of the water storage tank 5, the water flow will overflow from the connection and enter the inside of the water storage tank 5 for storage.

After the water pressure detection is completed and the sluice is closed, the elastic second spring 12 will push the top plate 10 to reset, thus blocking the detection pipe 3 to prevent the water containing iron slag from flowing back. After being adsorbed by the iron absorbing slate plates 14, a large amount of iron slag mixed in the water can be adsorbed. Then rotate the sealing cover plate 6. Due to the existence of the thread, the sealing cover plate 6 can be removed and the connection seat 15 and the iron absorbing slate plates 14 can be removed from the inside of the water storage tank 5. The water with the iron slag removed will be directly discharged, and then the iron slag adsorbed on the iron absorbing slate plates 14 can be disposed of.

[0024] Among them, on the top of the right end of the water storage tank 5, a display panel is fixedly installed. The plug rod 13 is installed in the middle of the inside of the right end of the water storage tank 5 through four fixing plates.

[0025] Among them, limiting sliding grooves are provided on the front and rear inner walls at the left end of the water storage tank 5. The inner diameter value of the connecting pipe 1 is greater than that of the detection pipe 3, and the inner diameter value of the detection pipe 3 is less than that of the water storage tank 5. Due to the existence of the limiting sliding grooves and the limiting plates 16, the cavity cylinder 11 can be ensured to be more stable when moving horizontally; the instantaneously ejected water flow will push the detection pipe 3 to move rightward, and the elastic first spring 8 and the connecting plate 9 cooperate to pull the detection pipe 3, which can provide a good buffering effect to weaken the impact force for the detection pipe 3.

[0026] Among them, threads are engraved on the outer surface of the inner side end of the sealing cover plate 6 and the inner wall of the right end of the water storage tank 5. The installation position of each magnetic iron plate 14 is located between every two fixing plates. Due to the existence of the threads, the sealing cover plate 6 can be rotated to install and disassemble with the water storage tank 5. The positions of the magnetic iron plates 14 are equally distributed, which is convenient for adsorbing iron slag in the water to the greatest extent.

[0027] Among them, lifting handles are fixedly installed on the left side of the upper end of the water storage tank 5 and the middle part of the right side of the sealing cover plate 6. The inner diameter value of the left end of the insertion rod 13 is adapted to the inner diameter value inside the cavity cylinder 11. It is convenient to carry the whole device through the lifting handle, and it is also convenient for the installation and disassembly of the sealing cover plate 6; the insertion rod 13 can well squeeze the second spring 12 inside the cavity cylinder 11.

[0029] First of all, the connector 2 can be connected to the connection port on the fire hydrant, and then the water gate of the fire hydrant is opened. The impact force generated by the instantaneously ejected water will push the detection pipe 3 to move rightward. Under the cooperation of a circle of elastic first springs 8 and the connecting plate 9, a simple buffering effect to weaken the impact force can be achieved. At the same time, the water pressure detector 4 can detect the water pressure of the fire hydrant and display it in the form of a numerical value on the display panel;

[0030] At the same time, the water flow will push the top plate 10 and the cavity cylinder 11 to move rightward, so as to cooperate with the insertion rod 13 to squeeze the second spring 12.

When the top plate 10 enters the inside of the water storage tank 5, the water flow will overflow from the connection and enter the inside of the water storage tank 5 for storage;

[0031] Then, the electromagnet plate 14 can adsorb the iron slag mixed in the water. After the water pressure detection is completed, the sluice gate is closed, and the elastic second spring 12 will push the top plate 10 to reset, thereby blocking the detection pipe 3, preventing the water containing iron slag from flowing back. Through the adsorption of the electromagnet plate 14, a large amount of iron slag mixed in the water can be adsorbed. Then, rotate the sealing cover plate 6. Due to the existence of the thread, the sealing cover plate 6 can be removed, and the connecting seat 15 and the electromagnet plate 14 can be removed from the inside of the water storage tank 5.
