Description

Technical Field

[0001] The utility model relates to the technical field of end water testing. More specifically, the utility model relates to a fire fighting end water testing device. Background Art

[0002] The end water testing device is usually installed at the nozzle of the most unfavorable point of the system pipe network, and is used to test the functions such as system startup, alarm and linkage. The end water testing device of the automatic sprinkler system is an important part of the sprinkler system, and plays a monitoring and detection role in the sprinkler system, which has very important significance.

[0003] At present, the end water testing device usually includes a valve before the meter, a pressure gauge, a water testing joint, a drain pipe, etc. In the prior art, due to the vibration of the pipeline during water testing, the water testing joint and the drain pipe are prone to dislocation, and the water splashing situation is very serious, wasting water resources. In order to solve the problem of water splashing during water testing, usually the water testing joint is fixed in the drain pipe, so that the water testing joint and the drain pipe are integrated. This method can well solve the problem of water splashing, but it also causes new problems, that is, when the water testing nozzle needs to be replaced, it cannot be replaced. The utility model patent with the application publication number CN210698590U discloses a spray end water testing bracket. The spray end water testing bracket connects the fire fighting pipe and the drain pipe through a support frame. When the drain pipe vibrates, the fire fighting pipe is driven to vibrate synchronously through the support frame to avoid the upper and lower drainage dislocation. However, when the support frame is in vibration for a long time, the expansion bolts connecting the support frame to the wall will also become loose, and the upper and lower drainage dislocation will still occur. Summary of the Invention

[0018] The second drain hopper part is arranged above the second drain hopper part. The water test joint is located in the space of the second drain hopper part. The material of the second drain hopper part is an elastic material. A long strip-shaped groove adapted to the long strip-shaped protrusion is arranged on the outer wall at the lower end of the second drain hopper part;

[0019] Wherein, the second drain hopper part is inserted into the first drain hopper part and the long strip-shaped protrusion is located in the long strip-shaped groove to detachably connect the second drain hopper part and the first drain hopper part.

And since the fire water pipe and the drain pipe are both connected to the first connecting plate, the fire water pipe and the drain pipe vibrate in the same frequency, and the up-and-down dislocation of the water test joint and the drain pipe is also avoided. In addition, a fire water pressure sensor is arranged between the normally open valve and the normally closed valve. If the water pressure in the fire water pipe is too high and reaches the set alarm value, an alarm signal will be sent to notify the patrol personnel to check.

[0032] Such as Figures 1 - 2As shown in the figure, an embodiment of the present utility model provides a fire-fighting end water testing device, including: a fire-fighting water pipe 1, which is vertically arranged, and a normally open valve 3, a fire-fighting water pressure sensor 19 and a normally closed valve 4 are sequentially arranged on the fire-fighting water pipe 1 from top to bottom. The lower end of the fire-fighting water pipe 1 is connected to a water testing joint 5; a drainage pipe 2, which is vertically arranged below the water testing joint 5, and a drainage funnel 6 is arranged at the upper end of the drainage pipe 2; a fixed support plate 7, which is vertically arranged on one side of the fire-fighting water pipe 1 and the drainage pipe 2, and a long groove 8 parallel to the central axis of the fire-fighting water pipe 1 is arranged on the fixed support plate 7. A plurality of first compression springs 10 are arranged on the opposite side walls of the long groove 8. A second compression spring 11 is arranged between two first compression springs 10 at the same height, and one end of each second compression spring 11 is fixed at the central axis position of the long groove 8; a first connecting plate 9, which is vertically arranged in the long groove 8, and the opposite side surfaces of the first connecting plate 9 are respectively connected to a plurality of first compression springs 10 on both sides. The side surface of the first connecting plate 9 away from the fire-fighting water pipe 1 is connected to a plurality of second compression springs 11; wherein, both the fire-fighting water pipe 1 and the drainage pipe 2 are connected to the first connecting plate 9.

[0033] In the above embodiment, specifically, an automatic exhaust valve 13 is further arranged above the normally open valve 3 to discharge the gas in the fire-fighting water pipe 1. Only during the water testing, the normally closed valve 4 will be opened. The normally open valve 3 is usually in the open state all the time. The normally open valve 3 adopts a manual valve, and the normally closed valve 4 can adopt a manual valve or an automatic valve. If an automatic valve is adopted, when testing is required, the automatic valve can be controlled to open by an external device. Since the automatic exhaust valve 13, the normally open valve 3 and the normally closed valve 4 are all prior arts, no detailed description will be given here.

[0034] Since in this embodiment, a fixed support plate 7 is provided on one side of the fire hose 1 and the drainage pipe 2, and the fixed support plate 7 is fixed to the vertical wall 12 by expansion screws 14, the fixed support plate 7 can also be fixed to other fixed objects. A long groove 8 parallel to the central axis of the fire hose 1 is provided on the fixed support plate 7. A plurality of first compression springs 10 are provided on opposite side walls of the long groove 8. A second compression spring 11 is also provided between two first compression springs 10 at the same height. The number of the first compression springs 10 and the second compression springs 11 is not specifically limited in this embodiment. Preferably, it can be set to 6. Therefore, when the first connecting plate 9 is arranged in the long groove 8, opposite side surfaces of the first connecting plate 9 are respectively connected to the plurality of first compression springs 10 on both sides, and one side surface of the first connecting plate 9 away from the fire hose 1 is connected to the plurality of second compression springs 11, so that the first connecting plate 9 can move forward, backward, left or right. After connecting the fire hose 1 and the drainage pipe 2 to the first connecting plate 9, during the water test of the fire hose 1 and the drainage pipe 2, the vibration caused by excessive water pressure will be buffered under the action of the first compression springs 10 and the second compression springs 11, and the amplitude of the vibration will also be reduced. And since the fire hose 1 and the drainage pipe 2 are both connected to the first connecting plate 9, the fire hose 1 and the drainage pipe 2 vibrate at the same frequency, which also avoids the vertical misalignment of the water test joint 5 and the drainage pipe 2. In addition, a fire water pressure sensor 19 is provided between the normally open valve 3 and the normally closed valve 4. If the water pressure in the fire hose 1 is too high and reaches the set alarm value, an alarm signal will be sent to notify the patrol personnel to check. The fire water pressure sensor 19 can be an existing one. For example, the NB-IOT pressure sensor is a high-performance pressure monitoring device integrating pressure acquisition and wireless data communication developed according to market demand. Other types of fire water pressure sensors 19 can also be used. It should be noted that since the first connecting plate is arranged in the space surrounded by the plurality of first compression springs and the plurality of second compression springs, the natural elongation length of the second compression spring cannot exceed the first compression spring. If Figure 1 in the direction, the second compression spring is completely located on the left side of the first compression spring.

[0035] In one specific embodiment, the specific setting method for connecting the fire hose 1 and the drainage pipe 2 to the first connecting plate 9 is:

[0036] At least one first connecting rod 15, the first connecting rod 15 is horizontally arranged, one end of the first connecting rod 15 is fixedly connected to the first connecting plate 9, and the other end is connected to the fire hose 1. Among them, a first clamp 16 is provided at one end of the first connecting rod 15, and the fire hose 1 is located within the first clamp 16 so that the first clamp 16 tightly holds the fire hose 1;

[0037] At least one second connecting rod 17, the second connecting rod 17 is horizontally arranged, one end of the second connecting rod 17 is fixedly connected to the first connecting plate 9, and the other end is connected to the drainage pipe 2; a second clamp 18 is provided at one end of the second connecting rod 17, and the drainage pipe 2 is located within the second clamp 18 so that the second clamp 18 tightly holds the drainage pipe 2.

[0038] In the above embodiment, the fire hose 1 is fixedly connected to the first connecting plate 9 through the first connecting rod 15, and the drainage pipe 2 is fixedly connected to the first connecting plate 9 through the second connecting rod 17. And a first clamp 16 is provided at one end of the first connecting rod 15 so that the fire hose 1 is located therein, and a second clamp 18 is provided at one end of the second connecting rod 17 so that the drainage pipe 2 is located therein. The settings of the first clamp 16 and the second clamp 18 facilitate both the fixation and disassembly of the first connecting rod 15 and the second connecting rod 17. When specifically setting, preferably, 2 to 3 first connecting rods 15 can be provided, and 2 to 3 second connecting rods 17 can also be provided.

[0039] In one specific embodiment, the drain funnel 6 includes:

[0040] A first drain part 61, which is fixedly connected to the end of the drainage pipe 2. The lower vertical section of the first drain part 61 is a symmetric arc, and the upper vertical section is a symmetric vertical line. A plurality of long strip-shaped protrusions are arranged at equal intervals on the inner wall of the upper end of the first drain part 61, and the long strip-shaped protrusions are vertically arranged;

[0041] A second drain part 60, which is arranged above the second drain part 60. The test water joint 5 is located in the space of the second drain part 60. The material of the second drain part 60 is an elastic material. Preferably, rubber is used, and other elastic hard materials can also be used. Long strip-shaped card slots adapted to the long strip-shaped protrusions are arranged on the outer wall of the lower end of the second drain part 60;

[0042] Among them, the second drain part 60 is inserted into the first drain part 61 and the long strip-shaped protrusions are located in the long strip-shaped card slots to detachably connect the second drain part 60 and the first drain part 61.

[0043] In the above embodiment, the drain funnel 6 is provided as a first drain funnel part 61 and a second drain funnel part 60 that are detachably connected. When it is necessary to replace the water test joint 5, the second drain funnel part 60 is moved upward to disengage the second drain funnel part 60 from the first drain funnel part 61, thereby exposing the water test joint 5 for replacement. After replacement, the second drain funnel part 60 is moved downward to connect the second drain funnel part 60 to the first drain funnel part 61. In addition, since the water test joint 5 is located in the space of the second drain funnel part 60, the water flowing out of the water test joint 5 directly enters the drain funnel 6, and the splashed water will also flow into the drain pipe 2 along the inner walls of the second drain funnel part 60 and the first drain funnel part 61, further avoiding the water splashing problem caused by the misalignment of the water test joint 5 and the drain pipe during the water test. When the water pressure is too high, although the fire hose 1 and the drain pipe 2 are both fixed on the first connecting plate 9 and vibrate at the same frequency, it is inevitable that the water test joint 5 and the drain funnel 6 will be slightly misaligned. The second drain funnel part 60 is made of an elastic material. When the water test joint 5 contacts the second drain funnel part 60, the elastic second drain funnel part 60 will also reduce the collision damage of the water test joint 5 to the second drain funnel part 60.

[0044] In one specific embodiment, as Figure 3 shown, the fire water pressure sensor 19 is connected to the signal input end of the controller through a signal line, and the controller is communicatively connected to the fire control center to transmit the alarm signal sent by the fire water pressure sensor 19 to the fire control center.

[0045] In the above embodiment, the fire water pressure sensor 19 is connected to the controller, and the controller is communicatively connected to the fire control center. Wireless communication or wired communication can be used. The alarm signal sent by the fire water pressure sensor 19 is transmitted to the controller, and the controller then transmits the alarm signal to the fire control center. The duty personnel in the fire control center can arrange fire inspection personnel to check the cause and restore water supply in time. The setting of the fire water pressure sensor 19 can timely detect whether the water pressure in the fire hose 1 is lower than the set allowable value, thereby eliminating potential hazards.

[0046] The number of devices and the processing scale described here are used to simplify the description of the present invention. The application, modification, and variation of the present invention are obvious to those skilled in the art.

[0047] Although the embodiments of the present utility model have been disclosed as above, it is not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present utility model. For those familiar with the field, additional modifications can be easily made.
