Description

Technical Field

[0001] This application relates to the technical field of fire hydrant testing, and in particular to an indoor fire hydrant safety testing device. Background Technology

[0002] Indoor fire hydrants are an important component of indoor fire hydrant systems. They generally include fire hydrant boxes fixed to the wall, as well as fire hydrant valves, nozzles, fire hoses, hose reels, and fire hoses arranged in the fire hydrant boxes. They are often installed in indoor spaces such as factories, warehouses, high-rise buildings, public buildings, and ships.

[0003] After fire hydrants are assembled, pressure testing is required using a testing device to ensure a normal supply of fire-fighting water. During the reliability testing of the closure seal of indoor fire hydrant valves, not only routine sealing tests are necessary, but also tests must be performed to check for seal failure under strong water pressure.

[0004] In actual testing, the valve to be tested needs to be manually installed in the test water circuit, and the valve disc closure point needs to be observed for leakage. After the test is completed, the valve needs to be disassembled. The staff are prone to fatigue from long-term installation and disassembly, which slows down the process and results in low testing efficiency. Summary of the Invention

[0005] To improve testing efficiency, this application provides an indoor fire hydrant safety testing device.

[0006] The indoor fire hydrant safety testing device provided in this application adopts the following technical solution: An indoor fire hydrant safety testing device, comprising: Water injection pipe is used to inject water into the fire hydrant that needs to be tested. The water injection pipe is equipped with an electrically controlled valve to control the opening or closing of the water injection pipe. A connecting pipe is rotatably connected at the outlet of the water injection pipe. A base is set on one side of the water injection pipe, and the fire hydrant is installed on the base. The fire hydrant and the water injection pipe are threadedly compatible. The connecting assembly is used to connect the inlet of the fire hydrant to the outlet of the water injection pipe. The connecting assembly includes a rotating assembly and a feeding assembly. The feeding assembly is used to drive the base to move closer to or away from the water injection pipe, and the rotating assembly is used to drive the connecting pipe to rotate.

[0007] Using the above technical solution, the feeding component moves the fire hydrant to be tested towards the connecting pipe, while the rotating component rotates the connecting pipe, thereby connecting the connecting pipe to the fire hydrant. At this point, the electrically controlled valve opens, completing the fire hydrant test. Connecting or disconnecting the fire hydrant from the connecting pipe is done mechanically, without the need for manual operation. The operating speed of the mechanical structure does not decrease with prolonged working time, thus improving testing efficiency.

[0008] Optionally, a fixed seat is provided between the water injection pipe and the base, and a drive motor is installed on the fixed seat. The rotating component includes a drive sprocket, a driven sprocket and a transmission chain. The drive motor is used to drive the drive sprocket to rotate. The driven sprocket is fixedly connected to the connecting pipe, and the transmission chain passes around the drive sprocket and the driven sprocket. The feeding assembly is connected to the fixed base. The feeding assembly includes two feeding screws. One end of each feeding screw is rotatably connected to the fixed base, and the other end of each feeding screw passes through the base. Both feeding screws are threadedly connected to the base. A transmission assembly is provided between the drive motor and the feed assembly, and the drive motor drives the feed screw to rotate through the transmission assembly.

[0009] Using the above technical solution, after the drive motor starts, it causes the driving sprocket to rotate. The driving sprocket, through a transmission chain, causes the driven sprocket to rotate, thereby rotating the connecting pipe. Simultaneously, the drive motor, through a transmission assembly, causes the feed screw to rotate, which in turn moves the fixed seat closer to or away from the connecting pipe. When the fixed seat is close to the connecting pipe, the connecting pipe is connected to the fire hydrant; when the fixed seat is away from the connecting pipe, the fire hydrant is separated from the connecting pipe. This structure achieves the effect of connecting and disconnecting the connecting pipe from the fire hydrant.

[0010] Optionally, the transmission assembly includes a transmission roller and a transmission belt. One end of the transmission roller is fixedly connected to the output shaft of the drive motor, and the other end of the transmission roller is fixedly connected to a main transmission wheel. A driven transmission wheel is fixedly connected to the feed screw, and the transmission belt passes over the main transmission wheel and the driven transmission wheel.

[0011] Using the above technical solution, after the drive motor starts, it causes the transmission roller to rotate. The transmission roller causes the driven roller to rotate through the main transmission wheel and the transmission belt, which in turn causes the feed screw to rotate. This achieves the effect of the drive motor driving the feed screw to rotate through the transmission assembly.

[0012] Optionally, a collection box is provided on the fixed base, and guide plates are fixedly connected to both sides of the collection box along the inclined direction, with the bottoms of the two guide plates close to each other.

[0013] Using the above technical solution, during the testing of fire hydrants, if a leak occurs, the leaked water falls onto the surface of the guide plate, and then slides down the guide plate into the collection box, thus achieving the effect of collecting the leaked water.

[0014] Optionally, a gravity sensor is installed inside the collection box. The gravity sensor is used to detect the weight inside the collection box and output a gravity signal. The output terminal of the gravity sensor is connected to a comparator. The comparator is used to compare the gravity signal with a reference value and output an execution signal. The output terminal of the comparator is connected to an alarm. The alarm is used in conjunction with the execution signal.

[0015] Using the above technical solution, if a leak occurs in the detected fire hydrant and the leaked water flows into the collection box, the gravity sensor outputs an execution signal through the comparator, which triggers the alarm corresponding to the fire hydrant, thus reminding the staff.

[0016] Optionally, a support is provided on the side of the base away from the fixed seat, and the end of the feed screw away from the fixed seat is rotatably connected to the support.

[0017] By adopting the above technical solution, the feed screw is supported by a support, thereby keeping the feed screw stable during rotation.

[0018] Optionally, the base is provided with a mounting seat, and the mounting seat has a mounting groove on the surface opposite to the base. The mounting seat has an annular cavity around the periphery of the mounting groove. The fire hydrant is installed in the mounting groove, and multiple mounting pieces are installed in the mounting groove. The mounting pieces are spaced apart around the central axis of the mounting groove. A trigger rod is fixedly connected to the side of the mounting piece opposite to the fire hydrant. The trigger rod passes through the mounting seat and extends into the annular cavity. An adjustment component for pressing the trigger rod is provided in the mounting seat.

[0019] Using the above technical solution, the trigger rod is pressed by the adjustment component, thereby causing the trigger rod to bring the mounting plate close to the fire hydrant until the mounting plate is pressed against the fire hydrant, thus installing the fire hydrant on the mounting base.

[0020] Optionally, the mounting base has a receiving groove annularly formed within the annular groove. The adjusting assembly includes a trigger cylinder, a gear ring, and a rack. The trigger cylinder is disposed within the receiving groove and is slidably fitted between the two. The trigger cylinder is used to press the trigger rod. The gear ring is sleeved on the trigger cylinder and the two are threadedly connected. The gear ring is rotatably connected to the mounting base. A through groove is formed through the mounting base and communicates with the receiving groove. The rack is disposed within the through groove and is slidably fitted between the two. The rack meshes with the gear ring and extends through the through groove to the outside. A rotating motor is mounted on the base, and a drive gear meshing with the rack is fixedly connected to the end of the output shaft of the rotating motor.

[0021] Using the above technical solution, after the rotating motor starts, the drive gear drives the rack to slide along the through groove. During the movement of the rack, the gear ring rotates, causing the trigger cylinder to move closer to or away from the trigger rod. When the trigger cylinder is close to the trigger rod, the trigger rod causes the mounting plate to press against the fire hydrant, thus fixing the fire hydrant to the mounting base. When the trigger cylinder moves away from the trigger rod, the fire hydrant can be removed from the mounting groove. Through this structure, the effect of fixing or removing the fire hydrant by moving the trigger rod is achieved.

[0022] Optionally, a mounting spring is fixedly connected to the side of the mounting plate away from the fire hydrant, and the end of the mounting spring away from the mounting plate is fixedly connected to the mounting base.

[0023] Using the above technical solution, when the trigger cylinder moves away from the trigger rod, the spring releases its elastic force, causing the mounting plate to move away from the fire hydrant, thereby achieving the effect of automatically resetting the mounting plate and releasing the fire hydrant.

[0024] Optionally, the base is provided with a placement groove that is compatible with the mounting seat for insertion.

[0025] By adopting the above technical solution, the position of the mounting base can be quickly located by placing the slot, thereby saving the time of the staff in positioning the mounting base and improving the efficiency of the test.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. After the drive motor starts, it rotates the driving sprocket, which in turn rotates the driven sprocket via a transmission chain, thus rotating the connecting pipe. Simultaneously, the drive motor rotates the feed screw via a transmission assembly, causing the fixed seat to move closer to or away from the connecting pipe. When the fixed seat is close to the connecting pipe, the connecting pipe connects to the fire hydrant, and the electrically controlled valve opens to complete the fire hydrant detection. When the fixed seat moves away from the connecting pipe, the fire hydrant separates from the connecting pipe. The connection and disconnection of the fire hydrant from the connecting pipe are both accomplished through a mechanical structure, thereby improving detection efficiency.

[0027] 2. After the motor starts, the drive gear drives the rack to slide along the through groove. During this movement, the rack rotates the gear ring, causing the trigger cylinder to move closer to or away from the trigger rod. When the trigger cylinder is close to the trigger rod, the trigger rod causes the mounting plate to press against the fire hydrant, thus fixing the fire hydrant to the mounting base. When the trigger cylinder moves away from the trigger rod, the mounting spring releases its force, causing the mounting plate to move away from the fire hydrant, thereby allowing the fire hydrant to be removed from the mounting groove. This structure achieves the effect of fixing or removing the fire hydrant. Attached Figure Description

The number of fire hydrants 10 is the same as the number of water injection pipes 1 and corresponds one-to-one.

[0033] Workers pre-install fire hydrants 10 on mounting bases 8. After the previous batch of fire hydrants 10 has been tested, workers first remove the mounting base 8 with the tested fire hydrant ring from the base 2, and then place the mounting base 8 with the fire hydrant 10 to be tested into the placement slot 22. During the testing process, workers install the next batch of fire hydrants 10 to be tested onto another mounting base 8.

[0034] refer to Figure 1 and Figure 2 The upper surface of the mounting base 8 has the same number of mounting grooves 81 as the water injection pipe 1. The fire hydrants 10 are installed in the mounting grooves 81 and correspond one-to-one. Multiple mounting pieces 83 are installed in the mounting grooves 81. The multiple mounting pieces 83 are evenly spaced around the central axis of the mounting groove 81. The mounting pieces 83 are arc-shaped, and the concave surface of the mounting pieces 83 is pressed against the bottom of the fire hydrant 10 inserted into the mounting groove 81.

[0035] refer to Figure 2 and Figure 3 The mounting base 8 has an annular cavity 82 around the mounting groove 81. The mounting base 8 has a receiving groove 85 on the inner bottom wall of the annular groove. A trigger rod 84 is fixedly connected to the convex surface of the mounting piece 83. The trigger rod 84 passes through the mounting base 8 and extends into the annular cavity 82. The trigger rod 84 is slidably adapted to the mounting base 8. An inclined surface is provided at the end of the trigger rod 84 that extends into the annular cavity 82. A mounting spring 87 is sleeved at one end of the trigger rod 84 in the mounting groove 81. The two ends of the mounting spring 87 are fixedly connected to the mounting piece 83 and the mounting base 8, respectively.

[0036] refer to Figure 2 An adjustment component 9 is provided inside the annular cavity 82. The adjustment component 9 includes a trigger cylinder 91 and a gear ring 92. The trigger cylinder 91 is set in the receiving groove 85 and the two are slidably adapted to each other. The inner wall of the trigger cylinder 91 near the trigger rod 84 has an inclined surface. The inclined surface of the trigger cylinder 91 is used to press the inclined surface of the trigger rod 84. The gear ring 92 is sleeved on the trigger cylinder 91 and the two are threadedly connected. The gear ring 92 is rotatably connected to the inner bottom wall of the mounting base 8 at the annular cavity 82.

[0037] refer to Figure 2 The mounting base 8 has a through groove 86 that is connected to the storage groove 85. The adjustment component 9 also includes a rack 93, which is set in the through groove 86 and the two slide together. The rack 93 meshes with the gear ring 92 and extends through the through groove 86 to the outside.

[0038] refer to Figure 1 A rotating motor 21 is installed on one side of the base 2, and a drive gear 211 that meshes with the rack 93 is fixedly connected to the end of the output shaft of the rotating motor 21.

[0039] Workers place the fire hydrant 10 into the installation slot 81 one by one, and then place the mounting base 8 into the placement slot 22. At this time, the rotating motor 21 is started. After the rotating motor 21 starts, it drives the drive gear 211 to rotate. The drive gear 211 drives the rack 93 to slide along the through slot 86. During the sliding process, the rack 93 drives the gear ring 92 to rotate. As a result, the gear ring 92 drives the trigger cylinder 91 to press the trigger rod 84. The trigger rod 84 drives the mounting plate 83 to press against the fire hydrant 10. At this time, the mounting spring 87 is in a stretched state, thereby fixing the fire hydrant 10 to the mounting base 8.

[0040] refer to Figure 1 A fixed seat 5 is provided between the water injection pipe 1 and the base 2. A drive motor 51 is installed at both ends of the fixed seat 5. A connecting assembly is provided between the water injection pipe 1 and the mounting base 8. The connecting assembly includes a feeding assembly 4, which is connected to the fixed seat 5. The feeding assembly 4 includes two feeding screws 41. One end of each feeding screw 41 passes through the fixed seat 5 and is rotatably connected to the fixed seat 5. A drive wheel 411 is fixedly connected to one end of the feeding screw 41 that passes through the fixed seat 5. The ends of each feeding screw 41 that are away from the fixed seat 5 pass through the base 2. Both feeding screws 41 are threadedly connected to the base 2. A support 7 is provided on the side of the base 2 away from the fixed seat 5. The ends of each feeding screw 41 that are away from the fixed seat 5 are rotatably connected to the support 7.

[0041] refer to Figure 4 A transmission assembly 6 is provided between the drive motor 51 and the feed assembly 4. The transmission assembly 6 includes a transmission roller 61 and a transmission belt 62. Both ends of the fixed base 5 are fixedly connected to a first support plate 88, which is arranged vertically. The transmission roller 61 is rotatably connected inside the first support plate 88. One end of the transmission roller 61 is fixedly connected to the output shaft of the drive motor 51, and the other end of the transmission roller 61 is fixedly connected to a main transmission wheel 611. The transmission belt 62 passes over the main transmission wheel 611 and the driven transmission wheel 411.

[0042] The drive motor 51 starts and drives the transmission roller 61 to rotate. The transmission roller 61 drives the main transmission wheel 611 to rotate. The main transmission wheel 611 drives the driven wheel 411 to rotate through the transmission belt 62. The driven wheel 411 drives the feed screw 41 to rotate. Thus, the feed screw 41 drives the base 2 to move. The base 2 drives the fire hydrant 10 to move through the mounting seat 8.

[0043] refer to Figure 1 and Figure 4An electrically controlled valve 11 is installed on the water injection pipe 1. The electrically controlled valve 11 opens or closes the water injection pipe 1 by electrical control. A second support plate 89 is fixedly connected to the surface of the fixed base 5 in the vertical direction. The number of second support plates 89 is the same as the number of water injection pipes 1 and they correspond one-to-one. A connecting pipe 12 is rotatably connected inside the second support plate 89. One end of the connecting pipe 12 is rotatably connected to the outlet of the water injection pipe 1. The inner wall of the connecting pipe 12 is provided with internal threads. The inner wall of the inlet end of the fire hydrant 10 is provided with external threads that are compatible with the internal threads.

[0044] refer to Figure 4 The connecting assembly also includes a rotating assembly 3, which includes a drive sprocket 31, a driven sprocket 32 ​​and a transmission chain 33. The drive sprocket 31 is mounted on the output shaft of the drive motor 51 and the two are fixedly connected. The driven sprocket 32 ​​is mounted on the connecting pipe 12 and the two are fixedly connected. The transmission chain 33 passes around the drive sprocket 31 and the driven sprocket 32.

[0045] The drive motor 51 starts and drives the drive sprocket 31 to rotate. The drive sprocket 31 drives the driven sprocket 32 ​​to rotate through the transmission chain 33. The driven sprocket 32 ​​drives the connecting pipe 12 to rotate. When the mounting base 8 moves the fire hydrant 10 closer to the connecting pipe 12, the water inlet end of the fire hydrant 10 is screwed into the connecting pipe 12, and then the electric control valve 11 is activated to open the water injection pipe 1. When the mounting base 8 moves the fire hydrant 10 away from the connecting pipe 12, the electric control valve 11 is activated to close the water injection pipe 1, and the water inlet end of the fire hydrant 10 is screwed out from the connecting pipe 12.

[0046] refer to Figure 4 The upper surface of the fixed base 5 is provided with a collection box 52. The number of collection boxes 52 is the same as the number of connecting pipes 12 and they correspond one-to-one. Both sides of the collection box 52 are fixedly connected with guide plates 521 along the inclined direction, and the bottoms of the two guide plates 521 are close to each other.

[0047] refer to Figure 4 and Figure 5 A gravity sensor is installed inside the collection box 52. The gravity sensor is used to detect the weight inside the collection box 52 and output a gravity signal. The output terminal of the gravity sensor is connected to a comparator. The comparator is used to compare the gravity signal with a reference value and output an execution signal. The output terminal of the comparator is connected to an alarm. The alarm is used in conjunction with the execution signal.

[0048] When the fire hydrant 10 leaks, the leaking water falls onto the surface of the guide plate and then slides down into the collection box 52. Once the water enters the collection box 52, the gravity sensor detects the weight and outputs a gravity signal. If the gravity signal is greater than the comparator's reference value, the comparator sends an execution signal, and the alarm starts sounding upon receiving the execution signal. When there is no water in the collection box 52, the gravity signal equals the comparator's reference value, the comparator sends a stop signal, and the alarm does not sound.

[0049] The implementation principle of an indoor fire hydrant safety testing device according to an embodiment of this application is as follows: After the operator places the fire hydrant 10 into the installation slot 81, the rotating motor 21 is started. The rotating motor 21 drives the rack 93 to rotate the gear ring 92 through the drive gear 211. As a result, the gear ring 92 presses the trigger rod 84 through the trigger cylinder 91, thereby fixing the fire hydrant 10 through the installation plate 83. After the drive motor 51 is started, the rotating assembly 3 drives the connecting pipe 12 to rotate. At the same time, through the transmission assembly 6 and the feeding assembly 4, the base 2 moves the fire hydrant 10 closer to the connecting pipe 12, thereby screwing the water inlet end of the fire hydrant 10 into the connecting pipe 12. At this time, the electric control valve 11 is activated to open the water injection pipe 1, thereby completing the testing of the fire hydrant 10.

[0050] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
