Description

Technical Field

[0001] The utility model relates to the technical field of water pressure detection of fire-fighting facilities, in particular to a building fire-fighting water pressure detection device. Background Art

[0002] Fire hydrants, formally called fire hydrants, are a type of fixed fire-fighting facility. Their main function is to control combustibles, isolate combustible materials, and eliminate ignition sources. They are divided into indoor fire hydrants and outdoor fire hydrants. Fire hydrant sets are generally composed of a fire box + fire hose + water gun + connector + plug + clip. Fire hydrants are mainly used for fire trucks to take water from the municipal water supply network or the outdoor fire water supply network to implement fire extinguishing. They can also be directly connected to water hoses and water guns to discharge water for fire extinguishing. Ensure that the fire hydrants are in normal condition to avoid the fire hydrants from being unable to be used normally when an accidental fire occurs. Personnel are required to check the water pressure of the fire hydrants at regular intervals.

[0003] However, in order to reduce the problem of water leakage, most of the existing fire water pressure detection equipment fixes the pressure gauge to the fire hydrant through a connecting component. To ensure accurate readings of the fixed pressure gauge, the readings can only be recorded by standing in front of the pressure gauge. For the recorder who is not standing in front of the pressure gauge, additional movement is required to record the readings, which causes inconvenience in recording. Summary of the invention

[0004] In view of the deficiencies in the prior art, the utility model provides a building fire water pressure detection device, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions:

[0006] The utility model discloses a building fire water pressure detection device, comprising a connecting pipe,

[0007] The mounting hole is opened on the surface of the connecting pipe;

[0008] The pressure gauge is installed inside the mounting hole;

[0009] The elastic ball is fixed to the outer surface of the connecting rod at the bottom of the pressure gauge;

[0010] A fixing plate is fixed to the outer surface of the connecting rod of the pressure gauge and is located below the elastic ball;

[0011] A plate is provided and installed on the outer ring of the fixed plate;

[0012] The control part is mounted on the outer surface of one end of the pressure gauge away from the fixed plate.

[0013] Furthermore, an external interface is fixed at one end of the connecting pipe, the external interface is clamped with the water outlet of the fire hydrant, and an internal interface is fixed on the inner wall of the connecting pipe near the external interface.

[0014] Furthermore, an outer connecting sleeve is sleeved on the outer surface of the connecting pipe.

[0016] Furthermore, a filter screen is installed at one end of the bottom of the pressure gauge.

[0017] Furthermore, a ball valve is installed inside the end of the connecting pipe away from the external interface.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] The utility model opens a mounting hole on the surface of a connecting pipe, movably installs a pressure gauge inside the mounting hole, fixes an elastic ball on the outer surface of the pressure gauge, and fixes an opening plate on the bottom of the elastic ball, so that the pressure gauge can be confined in the mounting hole, and the mounting hole is blocked by the elastic ball to prevent water inside the connecting pipe from gushing out of the mounting hole. When a person who detects and records the water pressure value is not standing in front of the pressure gauge, the pressure gauge can be rotated to face the person working there, so that the problem of the person working there having to move back and forth is avoided.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-4 , including a connecting pipe 2, a mounting hole 8, which is opened on the surface of the connecting pipe 2; a pressure gauge 9, which is installed inside the mounting hole 8; an elastic ball 10, which is fixed to the outer surface of the connecting rod at the bottom of the pressure gauge 9, and the outer diameter of the elastic ball 10 is larger than the inner diameter of the mounting hole 8. Through the elasticity of the elastic ball 10, when the water pressure of the fire hydrant 1 is tested, the connecting rod of the pressure gauge 9 can be deeply inserted into the connecting pipe 2, and the elastic ball 10 can be inserted into the mounting hole 8, so that the pressure gauge 9 blocks the mounting hole 8, and the water inside the connecting pipe 2 exerts pressure on the pressure gauge. 9 is impacted to make the pointer of the pressure gauge 9 rotate, so that the pressure gauge 9 displays the water pressure value of the fire hydrant 1, and the outer surface of the elastic ball 10 can directly rotate in place after blocking the mounting hole 8. The elastic ball 10 during rotation can continue to seal the mounting hole 8 through elastic force to prevent water from flowing out of the mounting hole 8; the fixing plate 11 is fixed to the outer surface of the connecting rod of the pressure gauge 9 and is located below the elastic ball 10; the opening plate 12 is installed on the outer circle of the fixing plate 11, and each opening plate 12 overlaps each other , and the end of one of the opening plates 12 is connected to a control line; the control member 13 is installed on the outer surface of the end of the pressure gauge 9 away from the fixed plate 11, and the control member 13 is connected to the opening plate 12 by a pull rope, and the pull rope passes through the inside of the elastic ball 10. By pressing the control member 13, the control member 13 pulls the pull rope. When the elastic ball 10 is inserted into the installation hole 8, all the opening plates 12 are retracted, so that the opening plates 12 can pass through the installation hole 8 normally and enter the inside of the connecting pipe 2. When the elastic ball 10 is stuck in the installation hole 8, After being installed inside the hole 8, the opening plate 12 is pulled outward by the control part 13. Since each group of opening plates 12 overlaps with each other, when the opening plate 12 connected to the pull rope is pulled outward, the other opening plates 12 are also tilted up. The tilted opening plates 12 are in an unfolded state. After the opening plates 12 are unfolded, the outer diameter is larger than the inner diameter of the installation hole 8, so that the opening plates 12 are stuck inside the connecting pipe 2, avoiding the elastic ball 10 from pushing upward when the water pressure inside the connecting pipe 2 is high, preventing the pressure gauge 9 from automatically detaching from the connecting pipe 2.

[0028] An external interface 3 is fixed to one end of the connecting pipe 2, and the external interface 3 is clamped with the water outlet of the fire hydrant 1. An internal interface 4 is fixed to the inner wall of the connecting pipe 2 near one end of the external interface 3, and the internal interface 4 is inclined toward the inside of the connecting pipe 2. An elastic sealing sheet is installed at the bottom between the external interface 3 and the internal interface 4. When the external interface 3 is clamped with the water outlet of the fire hydrant 1, the internal interface 4 is inserted into the inside of the water outlet of the fire hydrant 1. When the water inside the fire hydrant 1 passes into the inside of the connecting pipe 2, resistance is caused by the internal interface 4, and the internal interface 4 is pushed by the water flow, so that the water outlet of the fire hydrant 1 is more tightly connected to the external interface 3. At the same time, the elastic sealing sheet installed between the external interface 3 and the internal interface 4 can change with the distance between the water outlet of the fire hydrant 1 and the external interface 3, thereby reducing the occurrence of water leakage during detection.

[0029] The outer surface of the connecting pipe 2 is sleeved with an outer connecting sleeve 5, which is made of a hard material. The outer surface of the outer connecting sleeve 5 is connected with a handle. After the connecting pipe 2 is folded, the detection device can be lifted by the handle, so as to facilitate the movement of the device. A tripod 6 is fixedly connected to one side of the outer surface of the outer connecting sleeve 5, and a telescopic support rod 7 is movably connected to the side of the tripod 6 away from the outer connecting sleeve 5. When the connecting pipe 2 is connected and installed with the fire hydrant 1, the tripod 6 can be supported by the telescopic support rod 7, and then the outer connecting sleeve 5 can be supported by the tripod 6, so that the connecting pipe 2 can be firmly located on the side of the fire hydrant 1, reducing the movement problem of the connecting pipe 2 and the fire hydrant 1 after installation.

[0030] A filter screen 14 is installed at one end of the bottom of the pressure gauge 9. The outer diameter of the filter screen 14 is smaller than the inner diameter of the mounting hole 8, which facilitates the disassembly and assembly of the filter screen 14 with the pressure gauge 9. The filter screen 14 can effectively prevent impurities from entering the interior of the pressure gauge 9, reduce the damage caused by impurities to the pressure gauge 9, and increase the service life of the pressure gauge 9.

[0031] A ball valve 15 is installed inside the end of the connecting pipe 2 away from the external interface 3. The ball valve 15 controls the flow of the connecting pipe 2, so that the static water pressure and the water outlet pressure can be detected respectively.

[0032] Working principle: when testing the water pressure of the fire hydrant 1, the telescopic support rod 7 can be rotated first to make the telescopic support rod 7 perpendicular to the ground, and the bottom of the telescopic support rod 7 is supported on the ground by stretching, and the top of the telescopic support rod 7 supports the external connecting sleeve 5 through the tripod 6, so that the connecting pipe 2 inside the external connecting sleeve 5 is stably supported, and the connecting pipe 2 is placed on one side of the water outlet of the fire hydrant 1, and the external interface 3 is clamped with the water outlet of the fire hydrant 1 to connect the fire hydrant 1 to the connecting pipe 2, and the pressure gauge 9 is inserted from the mounting hole 8 opened on the surface of the connecting pipe 2, so that the elastic ball 10 is clamped into the mounting hole 8, and the control part 13 is pressed to expand the opening plate 12, so as to prevent the pressure gauge 9 from being separated from the connecting pipe 2 due to water pressure, and the ball valve 15 is used to control the pressure gauge 9 and the connecting pipe 2. The circulation of the fire hydrant 1 is convenient for detecting the static water pressure and dynamic water pressure of the fire hydrant 1 respectively, and due to the obstruction of the opening plate 12, the pressure gauge 9 can be rotated when reading the pressure gauge 9, and the elastic ball 10 can protect the pressure gauge 9 while blocking the mounting hole 8, which can not only avoid water leakage at the port of the mounting hole 8, but also prevent the pressure gauge 9 from colliding with the connecting pipe 2. The rotatable pressure gauge 9 can also make it more convenient for the detection personnel to read the readings. After the detection is completed, the pressure gauge 9 can be disassembled from the connecting pipe 2, and the blockage of the filter screen 14 can be checked to determine whether it needs to be replaced. Then the telescopic support rod 7 can be retracted and folded on one side of the connecting pipe 2 to reduce the space occupied by the entire device. Finally, the entire detection device can be lifted and moved by the handle on the outside of the external connecting sleeve 5.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
