Description

Technical Field

[0001] The present invention relates to the field of machinery, and particularly to a deluge valve detection device. Background Art

[0002] A deluge valve refers to a control valve that achieves automatic water supply by controlling the fire water supply pipeline, and can be opened by electric, hydraulic, pneumatic, and mechanical means. A water supply chamber, a control chamber, and a working chamber are provided inside the deluge valve. When a fire occurs, the detection device operates and relieves the pressure of the control chamber. The water pressure in the water supply chamber exceeds that in the control chamber, causing the valve flap in the control chamber to open. The water in the water supply chamber will pass through the working chamber and enter the corresponding pipeline to automatically spray water for fire extinguishing. Therefore, whether the deluge valve can work properly is related to people's life safety and property safety.

[0003] In order to ensure the normal operation of the deluge valve, before it is put into use or when it has not been used for a long time, it is necessary to detect and evaluate the health status of the deluge valve. Since the water pressure of the fire fighting water is relatively large compared to the water in general water pipes and has a high pressure bearing requirement for the inside of the deluge valve, a detection device that can detect the internal pressure bearing condition of the deluge valve is needed. Summary of the Invention

[0004] The purpose of the present invention is to provide a deluge valve detection device that can detect the maximum water pressure that the deluge valve can withstand, effectively recycle the detection water, and does not require too much effort to adjust the position of the deluge valve.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A deluge valve detection device includes a frame body, a plurality of detection seats, a main pipeline, and an injection pipeline. The main pipeline is arranged below the frame body, the detection seats are located above the main pipeline, and the side of the detection seat away from the main pipeline is an area where the deluge valve can be placed. A recovery channel for collecting liquid is provided inside the detection seat, and the recovery channel is communicated with the inside of the main pipeline; a pressing pipeline is arranged directly above the detection seat, a water pressure regulating device is arranged between the injection pipeline and the pressing pipeline, and an alarm component for detecting and feeding back the pressure bearing condition of the deluge valve and a transfer structure for transferring the deluge valve to the detection seat are also included.

[0007] Compared with the prior art, the deluge valve detection device adopting the above technical solutions has the following beneficial effects:

[0008] 1. By using the deluge valve detection device of the present invention, the deluge valve is placed between the detection seat and the downward pressure pipeline, and water in the liquid injection channel is injected into the downward pressure pipeline, so that the detection water enters the deluge valve. The internal water pressure is continuously increased by the water pressure regulating device. When the water pressure exceeds the bearing range of the deluge valve, the valve flap in the deluge valve will open, allowing water to pass through the deluge valve, and at the same time, the alarm component starts to operate and feedbacks to the staff.

[0009] 2. After the detection of the deluge valve is completed, the water will pass through the channel and enter the main pipeline, realizing the proper treatment of the detection water, thus avoiding the detection water flowing to the outside and causing the detection workshop to flood. And since each detection seat is relatively independent, multiple deluge valves can be detected simultaneously through multiple detection seats, effectively improving the detection efficiency of the staff.

[0010] 3. With the help of the transfer structure, the deluge valve can be directly placed above the detection seat, eliminating the cumbersome and inconvenient process of moving the relatively heavy deluge valve up and down, avoiding the energy consumption of the detection personnel when dealing with multiple deluge valves, and reducing the time consumed by the detection work.

[0011] Preferably, it further includes a control component for controlling the up and down displacement of the downward pressure pipeline. The control component includes a hydraulic cylinder, a movable rod and a docking seat. The hydraulic cylinder is connected to the frame body. The movable rod is movably arranged in the hydraulic cylinder, and the end of the movable rod away from the hydraulic cylinder is connected to the downward pressure pipeline through the docking seat. It also includes a sealing ring made of a resilient material, and the shape of the sealing ring is adapted to the base of the existing deluge valve. By controlling the downward displacement of the downward pressure pipeline to appropriately press the deluge valve, the clamping effect of the downward pressure pipeline and the detection seat on the deluge valve is realized, so that the downward pressure pipeline, the detection seat and the deluge valve are closely fitted. While injecting water into the deluge valve, the risk of detection water overflow is effectively reduced. And by using the control structure of the hydraulic cylinder, the movement process of the downward pressure pipeline is smooth and stable, which is conducive to the accurate control of the downward pressure degree. By arranging sealing rings between the deluge valve and the downward pressure pipeline, and between the deluge valve and the detection seat, an effective waterproof layer is formed, further reducing the risk of detection water overflow. And by using the characteristics of the resilient material, the service life of the sealing ring is increased, which is convenient for subsequent use.

[0012] Preferably, the liquid injection pipeline is internally connected to the downward pressure pipeline through a water injection pipe, and the water pressure regulating device is arranged at the connection of the liquid injection pipeline and the water injection pipe. By setting a separate water injection pipe and a water pressure device, the water injection and pressure detection operations for a single detection seat can be realized, so as to meet the detection requirements for deluge valves in different conditions at the same time.

[0013] Preferably, the alarm component includes a flow sensor, a control unit, and an alarm. The flow sensor is disposed inside the channel, and the control unit and the alarm are both arranged in the detection seat. The control unit is respectively connected to the flow sensor and the alarm. Through real-time monitoring of the inside of the channel of the detection seat, when water passes through the channel, it indicates that the water pressure borne by the detected deluge valve has exceeded the range, and the alarm starts to operate, so as to quickly find the deluge valve that needs to suspend the detection and remind the staff to check and record.

[0014] Preferably, the transfer structure includes a lifting platform, a fixed seat, and a clamping arm. The lifting platform is disposed on one side of the detection seat away from the liquid injection pipeline, and the fixed seat is disposed on one side of the detection seat away from the lifting platform. The clamping arm is movably disposed in the lifting platform through a positioning rod. The clamping arm can be rotatably connected and clamped to the positioning rod. A guide rail for the displacement of the positioning rod is provided between the lifting platform and the fixed seat. An activity frame and an adjustment component for controlling the up and down displacement of the activity frame are provided in the lifting platform, and the displacement of the activity frame drives the positioning rod to move synchronously. By controlling the up and down movement of the activity frame, the height of the deluge valve placed on it is changed, and the positioning rod and the clamping arm are transferred through the guide rail. Since the guide rail is located on the side of the detection seat, while driving the positioning rod and the clamping arm to move, the force on the clamped deluge valve is transferred above the detection seat.

[0015] Preferably, an activity groove and a liquid storage bin for storing hydraulic oil are provided in the lifting platform. The activity frame slides up and down in the activity groove and the lifting platform. The adjustment component includes a liquid extraction channel, a liquid inlet channel, a liquid return channel, an adjustment channel, and a pedal. The liquid extraction channel, the liquid inlet channel, the liquid return channel, and the adjustment channel are all arranged in the lifting platform. One end of the liquid extraction channel and one end of the liquid inlet channel are jointly connected to the adjustment channel. The end of the liquid extraction channel away from the adjustment channel is connected to the liquid storage bin, and the end of the liquid inlet channel away from the adjustment channel is connected to the activity groove. The liquid return channel is provided between the liquid storage bin and the activity groove, and one-way valves are provided in both the liquid inlet channel and the liquid return channel. A blocking member is provided in the liquid return channel, and a pull button connected to the blocking member is movably provided on the lifting platform. The pedal is movably disposed on one side of the lifting platform through a telescopic rod. A piston is provided in the adjustment channel, and a linkage component is provided between the telescopic rod and the piston. Stepping on or releasing the pedal controls the reciprocating displacement of the piston in the adjustment channel.

[0016] Only by stepping on the pedal can the piston be driven to move in the adjustment channel, achieving a pumping and pushing effect similar to that of a syringe, and then transferring the hydraulic oil in the liquid storage chamber to the movable groove, pushing the movable frame upward to raise the clamping arm and the deluge valve. It has the characteristics of convenient and efficient use. During the operation of controlling the displacement by stepping, the inspector's line of sight can directly observe the height of the deluge valve to pause or continue the raising operation in time. The displacement of the plug can be driven by the pull button, so that the hydraulic oil in the movable groove returns to the liquid storage chamber through the liquid return channel to lower the height of the deluge valve. Moreover, there is no need to manually carry up and down the nearly ten-kilogram deluge valve, which can save the time and energy of the inspector to handle more deluge valve detections.

[0017] Preferably, the linkage assembly includes a convex tooth portion and an adjustment gear. The adjustment gear is rotatably arranged on the side wall of the lifting platform. Convex tooth portions are provided on the side walls of the telescopic rod and the piston, and the convex tooth portion is meshed and connected with the adjustment gear. A return spring or an elastic block is provided at the bottom of the telescopic rod. Since the convex tooth structures on the convex tooth portion and the adjustment gear are evenly spaced, the stability of the displacement of the telescopic rod is effectively increased, and the precise adjustment of the lifting amplitude of the deluge valve is facilitated.

[0018] Preferably, an electronic control unit is provided in the fixed seat. An electronically controlled rod connected to the electronic control unit is slidably arranged in the guide rail. A limiting groove is provided at the end of the electronically controlled rod facing the lifting platform. A limiting block is provided on one side of the positioning rod facing the guide rail. The positioning rod moves up and down to make the limiting block enter and exit the limiting groove. By using the cooperation relationship between the limiting block and the limiting groove, when the positioning rod and the electronically controlled rod are on the same horizontal plane, the displacement of the electronically controlled rod can directly drive the positioning rod into the guide rail to achieve the purpose of driving the deluge valve to translate.

[0019] Preferably, a micro switch is provided in the guide rail. When the limiting block moves and contacts the micro switch, the electronically controlled rod receives a stop signal synchronously. By using the characteristics of the micro switch being sensitive and fast in response, after the deluge valve is displaced to the required position, the electronic control unit immediately pauses the displacement action of the electronically controlled rod, so that the deluge valve is accurately placed in the detection area, improving the accuracy of the detection result and avoiding the accident of water leakage caused by the wrong placement of the deluge valve.

[0020] Preferably, the fixed seat is provided with a sliding groove for the displacement of the guide rail, and the electronic control unit controls the upward displacement of the guide rail. By using the cooperation relationship between the sliding groove and the guide rail, during the process of controlling the translation of the deluge valve, the height of the deluge valve can be further finely adjusted to increase the accuracy of the placement position of the deluge valve.

[0041] The lifting platform 5 is provided with a movable groove 51 and a liquid storage bin 52 for storing hydraulic oil. The movable frame 50 slides up and down in the movable groove 51 and the lifting platform 5. The lifting platform 5 is provided with a movable frame 50 and an adjusting assembly for controlling the up and down displacement of the movable frame 50.

[0044] The fixed seat 6 is provided with an electronic control unit and corresponding control buttons. An electronic control rod 80 and a micro switch 82 connected to the electronic control unit are slidably arranged in the guide rail 8. A limit groove 81 is arranged at the end of the electronic control rod 80 facing the lifting platform 5. A limit block 71 is arranged on one side of the positioning rod 70 facing the guide rail 8. The positioning rod 70 moves up and down so that the limit block 71 enters and exits the limit groove 81. When the limit block 71 moves and contacts the micro switch 82, the electronic control unit sends a stop signal to the electronic control rod 80.

[0045] The fixed seat 6 is provided with a sliding groove 60 for the displacement of the guide rail 8. When the limit block 71 contacts the micro switch 82, the electronic control unit controls the guide rail 8 to move upward.

[0046] The following is the usage method of this embodiment:

[0047] First, a sealing ring 4 is placed on the test seat 10, and the tester uses an existing trolley to move the rain valve 0 to one side of the lifting platform 5, and translates the rain valve 0 to the middle of the lifting platform 5. Then, the clamping arm 7 and the positioning rod 70 are fixed together by the connection method of the clamping arm 7 and the positioning rod 70, and the concave part of the clamping arm 7 is located at the concave part of the rain valve 0.

[0048] After that, the inspector begins to step on the pedal 57, the return spring 93 is forced to contract and the telescopic rod 90 is forced to move downward, so that the convex tooth portion 91 located at the telescopic rod 90 drives the adjusting gear 92 to rotate synchronously. At the same time, due to the meshing connection between the adjusting gear 92 and the convex tooth portion 91 on the piston 560, the piston 560 is forced to move in a direction away from the adjusting channel 56, achieving the effect of pumping the piston 560. At this time, due to the increase in space and decrease in pressure in the adjusting channel 56, the hydraulic oil in the liquid storage tank 52 and the pumping channel 53 is displaced in the direction of the adjusting channel 56, and the one-way valve at the pumping channel 53 is forced to open, while the one-way valve located at the liquid inlet channel 54 is blocked. When the pedal 57 is released, the return spring 93 drives the telescopic rod 90 to return to its original position, causing the piston 560 to move toward the regulating channel 56. At this time, the one-way valve located at the pumping channel 53 is blocked by force, and the one-way valve located at the liquid inlet channel 54 is opened, so that part of the hydraulic oil in the regulating channel 56 passes through the liquid inlet channel 54 and enters the movable groove 51. According to Pascal's law, the movable frame 50 will be pushed upward, so that the rain valve 0, the positioning rod 70 and the clamping arm 7 are moved upward synchronously.

[0049] If it is necessary to lower the height of the clamping arm 7, the button 580 is directly pulled upward to drive the blocking member 58 to move synchronously, so that a channel is formed inside the liquid storage tank 52, the return liquid channel 55 and the movable groove 51, and part of the hydraulic oil in the movable groove 51 will pass through the return liquid channel 55 and return to the liquid storage tank 52, and the movable frame 50 will move downward at the same time.

[0050] When the positioning rod 70 is displaced and is in the same horizontal plane as the guide rail 8, Figure 8 As shown, when the limit block 71 at the end of the positioning rod 70 enters the limit groove 81 at the end of the electric control rod 80, the control button relative to the fixed seat 6 is pressed, and the electric control rod 80 drives the positioning rod 70 to move synchronously, and the positioning rod 70 enters the guide rail 8. After the electric control rod 80 moves a specific distance, the electric control rod 80 stops moving, and the electric control unit drives the guide rail 8 to move upward appropriately, so that the rain shower valve 0 is appropriately lifted above the sealing ring 4 on the detection seat 10; then the electric control rod 80 is controlled to move until the end of the positioning rod 70 contacts the micro switch 82 in the guide rail 8. At this time, the electric rod stops moving, and the electric control unit drives the guide rail 8 to move downward appropriately, so that the rain shower valve 0 is placed on the sealing ring 4 on the detection seat 10.

[0051] When the transfer operation of the deluge valve 0 is completed, another sealing ring 4 is placed above the deluge valve 0. Then, the movable rod 31 is controlled by the hydraulic cylinder 30 to move downward, and the lower end of the downward pressure pipe 12 is pressed toward the deluge valve 0. At this time, the detection seat 10 and the downward pressure pipe 12 clamp the deluge valve 0.

[0052] Open the control valve at the water pressure regulating device 20, and the water in the injection channel will pass through the water injection pipe 21 and the pressure pipe 12 in sequence until the water is injected into the deluge valve 0. The water pressure is gradually increased by the water pressure regulating device 20. If the water pressure exceeds the limit that the deluge valve 0 can withstand, the valve disc in the deluge valve 0 will be opened, and the water will pass through the deluge valve 0, pass through the detection seat 10, and enter the main pipeline 11. The flow sensor feeds back the flow of water to the control unit, and the control unit controls the alarm to start running. At the same time, the alarm part of the deluge valve 0 also starts to run. The staff can learn the pressure bearing capacity of the deluge valve 0 based on the corresponding data of the water pressure regulating device 20.

[0053] The above is a preferred embodiment of the present invention. A person skilled in the art may make several modifications and improvements without departing from the principle of the present invention, and these modifications and improvements shall also be considered as the protection scope of the present invention.
