Description

Technical Field

[0001] The utility model relates to the technical field of fire equipment detection, in particular to an auxiliary detection mechanism for fire equipment. Background Technique

[0002] The standards of fire water pressure are related to factors such as the height of the building and the degree of crowd density. Generally speaking, the water pressure standard for public places is 0.1 MPa, the water pressure standard for places with a large flow of people is 0.13 MPa, and the pressure test standard for other places is 0.07 MPa. At the same time, for every 10 meters increase in the building, the water pressure standard should be increased by 0.1 MPa accordingly.

[0003] The existing publication number: CN218729387U discloses a leakage detection mechanism for indoor fire equipment, including a fire box. A cabinet door is arranged on the front outer surface of the fire box, a fire equipment is arranged on the front inner surface of the fire box, a detection mechanism is arranged on one side of the fire equipment, and the detection mechanism includes an inclined plate, a controller, an alarm, an installation frame, a placement groove, a hole groove, a key plate, a fixing rod, a lifting groove, a spring, a T-shaped plate, a handle, a cover plate, a rubber pad, a key groove and an ultrasonic detector. The controller is located on the outer surface of one side of the fire box. The disclosed leakage detection mechanism for indoor fire equipment can conveniently detect and alarm leaks. The alarm can timely remind the staff to carry out maintenance, is convenient for installing and disassembling the ultrasonic detector, is convenient for limiting the ultrasonic detector, and at the same time, the installation frame can protect the ultrasonic detector and improve the service life of the ultrasonic detector.

[0004] The above existing problems: Insufficient water pressure of fire equipment will lead to poor fire extinguishing effect, while too high water pressure may damage the equipment or affect normal use. Therefore, regularly detecting the fire water pressure can ensure that it always remains within the standard range. In the comparison case, installing and protecting the ultrasonic detector cannot directly detect; thus, it does not meet the existing needs. For this reason, we propose an auxiliary detection mechanism for fire equipment. Content of the Utility Model

[0005] The purpose of the utility model is to provide an auxiliary detection mechanism for fire equipment to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An auxiliary detection mechanism for fire equipment, including: a docking head in a tee shape, one pipe head of the docking head is connected with a fire nozzle, the other pipe head is connected with a switch assembly, and a water pressure mechanism is sleeved at the middle part of the docking head.

[0007] The water pressure mechanism includes an upper block and a lower arc-shaped plate; the upper block has an arc-shaped groove, and together with the lower arc-shaped plate, it clamps the docking head; on both sides of the upper block, there are accommodation grooves, and the lower arc-shaped plate has clamping bars, which extend into the accommodation grooves and are locked by internal hexagonal bolts 9;

[0008] The upper block has a central hole, and the pipe head in the middle of the docking head extends into this central hole. A water pressure gauge is screwed into this central hole, and the water pressure gauge is communicated with the docking head;

[0009] The right side of the fire fighting nozzle is communicated with the fire pump through a water hose;

[0010] When it is necessary to measure the water pressure of the fire pump, directly dock the fire fighting nozzle with the fire pump and turn on the pump to measure; when it is necessary to measure the water pressure during fire fighting, turn on the switch assembly to measure.

[0011] As a preferred technical solution of this application, both sides of the upper opening respectively have integral horizontal bars, and accommodation grooves are opened on the horizontal bars; on both sides of the lower arc-shaped plate, corresponding clamping bars are respectively arranged through corresponding support plates.

[0012] As a preferred technical solution of this application, the lower end of the water pressure gauge has a connecting ring, and the connecting ring is in threaded fit with the central hole of the upper block; a sealing ring is sleeved on the pipe head in the middle of the docking head, and when the pipe head is inserted into the central hole, it is hermetically connected through the sealing ring.

[0013] As a preferred technical solution of this application, the upper end face of the pipe head in the middle of the docking head is opposite to the lower end face of the connecting ring, and a sealing ring gasket is placed between the two.

[0014] As a preferred technical solution of this application, the switch assembly includes a valve body, the left side of the docking head is movably connected with the valve body, and the right side of the valve body is movably connected with a handle through a rotating shaft.

[0015] This utility model has at least the following beneficial effects:

[0016] 1. By inserting and fixing the fire fighting nozzle with the docking head, then holding the upper block and clamping it from top to bottom on the top of the docking head so that the water pressure gauge extends into the inside of the docking head, and then taking out the lower arc-shaped plate and sleeving it from bottom to top on the bottom of the docking head. The upward movement of the lower arc-shaped plate drives the support plate and the clamping bar to move accordingly. The upward movement of the clamping bar deepens into the inside of the horizontal bar. Then take out the internal hexagonal bolt and insert it from bottom to top through the clamping bar in sequence and extend into the inside of the horizontal bar, and rotate the internal hexagonal bolt clockwise to tighten to complete the connection between the lower arc-shaped plate and the upper block. The upper block remains fixed on the surface of the docking head so that the water pressure gauge will not be loosened by the pressure during use and affect the accuracy of the detection data;

[0017] And the structure is simple.

[0018] 2. By tightening the valve body on the left side of the docking head, the valve body is installed with the docking head through threads and the handle is rotated clockwise. The rotation of the handle drives the ball valve inside the valve body to rotate and close the inside of the valve body. When the fire pump starts to generate water pressure, the water pressure is transmitted through the fire nozzle to the inside of the valve body and cannot rush out, ensuring that the water pressure gauge can accurately obtain whether the water pressure inside the fire nozzle is normal.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0028] It includes a docking head 2 in the shape of a three-way tube. One tube head of the docking head 2 is connected with a fire nozzle 1, and the other tube head is connected with a switch assembly 4. A water pressure mechanism 3 is sleeved in the middle of the docking head 2; the right side of the fire nozzle 1 is connected to a fire pump through a water hose;

[0029] Among them, the water pressure mechanism 3 includes an upper block 31 and a lower arc plate 36; the upper block 31 has an arc groove, which together with the lower arc plate 36 clamps the docking head 2; accommodation grooves 5 are provided on both sides of the upper block 31, and the lower arc plate 36 has clamping strips 38, and the clamping strips 38 extend into the accommodation grooves 5 and are locked by internal hexagonal bolts 39;

[0030] Moreover, the upper block 31 has a central hole, and the pipe head in the middle of the docking head 2 extends into this central hole, and a water pressure gauge 34 is screwed into this central hole, and the water pressure gauge 34 communicates with the docking head 2;

[0031] When it is necessary to measure the water pressure of the fire pump, directly dock the fire hose nozzle 1 with the fire pump and turn on the pump to measure it; when it is necessary to measure the water pressure during fire extinguishing, turn on the switch assembly 4 to measure it.

[0032] Refer to Figure 3 and Figure 4 In this embodiment, integral cross bars 35 are respectively provided on both sides of the upper opening 31, and accommodation grooves 5 are formed in the cross bars 35; clamping strips 38 are respectively provided on both sides of the lower arc plate 36 through corresponding support plates 37.

[0033] Refer to Figure 3 In this embodiment, the lower end of the water pressure gauge 34 has a connection ring 33, and the connection ring 33 is in threaded fit with the central hole of the upper block 31; a sealing ring 6 is sleeved on the pipe head in the middle of the docking head 2, and when the pipe head is inserted into the central hole, it is hermetically connected through the sealing ring 6; in addition, in order to dock and seal more simply, a sealing ring gasket is placed on the upper end face of the pipe head in the middle of the docking head 2, opposite to the lower end face of the connection ring 33. When measuring the water pressure, due to the action of the sealing ring 6 and the sealing ring gasket, through this simple structure, the water in the docking head 2 can smoothly enter the water pressure gauge 34 to complete the measurement of the pressure.

[0034] Refer to Figure 5 In this embodiment, the switch assembly 4 includes a valve body 41, the left side of the docking head 2 is movably connected with the valve body 41, and the right side of the valve body 41 is movably connected with a handle 42 through a rotating shaft.

[0035] When the auxiliary detection mechanism of the present utility model is working:

[0036] The user connects the fire hose nozzle 1 to the fire pump, then plugs the docking head 2 on the left side of the fire hose nozzle 1, and then holds the upper block 31 to move the whole and place it on the top of the docking head 2. The upper block 31 is fitted and sleeved on the surface of the docking head 2. Then, the upper block 31 makes the pressure gauge 34 accurately inserted into the inside of the docking head 2 through the connecting block 32 and the connecting ring 33. Then, hold the lower arc plate 36 and sleeve it on the surface of the docking head 2 from bottom to top, so that the support plate 37 and the clamping strip 38 move along with it. When the lower arc plate 36 fits the bottom of the docking head 2, the clamping strip 38 is inserted into the receiving groove 5 of the cross bar 35. Then, take out the hexagon socket head bolt 39, and the hexagon socket head bolt 39 is inserted into the inside of the clamping strip 38 and the cross bar 35 from bottom to top through the screw hole, and rotate the hexagon socket head bolt 39 clockwise to fix the clamping strip 38 and the cross bar 35. The fixing of the clamping strip 38 and the cross bar 35 makes the upper block 31 on the top and the lower arc plate 36 on the bottom of the docking head 2 firmly fixed on the docking head 2. Then, take out the valve body 41 and screw it tightly with the left side of the docking head 2 through the thread 7, and rotate the handle 42 to close the valve body 41. Finally, turn on the fire pump to work. The air pressure generated by the fire pump enters the inside of the docking head 2 and the valve body 41 through the fire hose nozzle 1. The air pressure is restricted by the closed valve body 41 and cannot leak out, so that the pressure gauge 34 can accurately read the air pressure inside the fire hose nozzle 1. Manually record the data to complete the detection, and turn off the fire pump and reverse the operation to remove all components and restore the fire hose nozzle 1;

[0037] The fire hose nozzle 1 is completed with the plug-in fixation of the docking head 2. Take out the valve body 41 and screw it tightly with the left side of the docking head 2 through the thread 7. The valve body 41 is fixed on the left side of the docking head 2 and then rotate the handle 42 clockwise. The rotation of the handle 42 makes the ball head inside the valve body 41 rotate to close the internal space of the valve body 41. When the air pressure inside the fire hose nozzle 1 rushes into the valve body 41 through the docking head 2, it is restricted by the closed space so that the air pressure will not leak, which is convenient for the pressure gauge 34 to accurately detect;

[0038] Screw holes are provided on the left and right sides of the surfaces of the cross bar 35 and the clamping strip 38 and corresponding to the positions of the hexagon socket head bolts 39; Through the setting of the receiving groove 5, the clamping strip 38 can completely enter the inside of the cross bar 35 through the receiving groove 5, avoiding the phenomenon that the clamping strip 38 is stuck inside the cross bar 35 due to the too narrow width of the receiving groove 5.

[0039] It should be noted that the material of the lower arc plate 36 is stainless steel, and the diameter of the lower arc plate 36 is larger than the diameter of the docking head 2; Through the setting of the lower arc plate 36, the corrosion resistance of the lower arc plate 36 can be increased, avoiding the phenomenon that the lower arc plate 36 is rusted and oxidized due to the influence of water stains.

[0040] This application also discloses an auxiliary detection mechanism for fire fighting equipment. If the water pressure of the fire fighting equipment is insufficient, the fire extinguishing effect will be poor, and if the water pressure is too high, it may damage the equipment or affect the normal use.
