Description

Technical Field

[0001] The invention relates to the technical field of sprinkler detection, and in particular to a detection device for fire sprinkler pipelines. Background Art

[0002] A fire sprinkler is a type of sprinkler that automatically starts up within a predetermined temperature range under the action of heat, or is started up by a control device based on a fire signal, and sprays water to extinguish fire according to the designed spraying shape and flow rate. It is part of a sprinkler system. Fire sprinkler heads are used in fire sprinkler systems. When a fire occurs, water is sprayed through the sprinkler splash plate to extinguish the fire. They are divided into pendent sprinkler heads, upright sprinkler heads, ordinary sprinkler heads, side wall sprinkler heads, etc. After the fire sprinkler heads are produced, they need to be tested for water flow in order to verify their performance.

[0003] A fire sprinkler detection device is disclosed in the patent with the announcement number CN116026578B. The present invention relates to the technical field of detection devices, including a water tank and a fire sprinkler body. Two support plates are symmetrically fixedly installed on the upper surface of the water tank, a test tube is fixedly installed between the two support plates, and a connecting plate is detachably installed on the lower surface of the test tube. After the moving block moves away from the connecting block, the connecting block will push the sealing block to reset under the elastic force of the compression spring, close the opening of the test tube, and as the moving block continues to move, the water in the test tube can be passed into the fire sprinkler body in turn, so that multiple fire sprinkler bodies can be tested for water flow in turn at one time;

[0004] The above-mentioned related technologies have the following defects: when installing fire sprinklers, it is necessary to manually install each fire sprinkler on the connecting pipe in turn with the help of tools. The operation is cumbersome and the detection amount of fire sprinklers is large. The above-mentioned fire sprinkler installation method seriously affects the detection efficiency of fire sprinklers. Secondly, in order to avoid the mutual influence of fire sprinklers during water flow test, the above-mentioned technology adopts the method of testing each fire sprinkler one by one. This method will increase the time of fire sprinkler detection and also affect the detection efficiency. Even if the existing technology achieves the effect of simultaneous detection of each fire sprinkler by increasing the distance between fire sprinklers, when detecting more fire sprinklers at the same time, it will cause the detection device to occupy a larger area. For this reason, this scheme proposes a detection device for fire sprinkler pipes. Summary of the invention

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Example: See Figure 1 - Figure 7A detection device for a fire sprinkler pipe comprises a box 1, the top and bottom of the box 1 are both open structures, four column feet 4 are installed at the bottom of the box 1, and also comprises:

[0036] A main flow pipe 2 is rotatably connected to the inside of the box 1, and one end of the main flow pipe 2 is connected to the water supply equipment through a rotary connector 5;

[0037] The flow dividing mechanism is provided with multiple groups. In this embodiment, the flow dividing mechanism is provided with three groups. The multiple groups of flow dividing mechanisms are distributed in a ring array with the main flow pipe 2 as the center. The flow dividing mechanism includes multiple flow dividing pipes 3 installed on the main flow pipe 2. The multiple flow dividing pipes 3 are evenly distributed along the length direction of the main flow pipe 2;

[0038] A positioning mechanism, which is provided with multiple groups and corresponds to the shunt pipe 3, and is used to position the fire sprinkler 26, and the positioning mechanism includes a turntable 6, a positioning groove 7 penetrating the inside of the turntable 6, a cylinder 8 installed inside the turntable 6, and a limit block 9 fixed to the extended end of the cylinder 8;

[0039] The staff inserts the threaded end of the fire sprinkler 26 into the positioning groove 7 with the threaded end facing downward, and the threaded end of the fire sprinkler 26 extends to the outside of the positioning groove 7. The staff then controls the cylinder 8 to extend to drive the limit block 9 to move synchronously. The fire sprinkler 26 is limited by the limit block 9, so that when the support plate 13 is driven to revolve around the mainstream pipe 2, the fire sprinkler 26 will not move along the inside of the positioning groove 7, thereby ensuring the stability of the fire sprinkler 26.

[0040] The supporting mechanism is provided with multiple groups. The supporting mechanism in this embodiment is provided with three groups, and corresponds to the multiple diversion mechanisms. The supporting mechanism is used to support the positioning mechanism. The supporting mechanism includes a driving block 10 fixedly sleeved on the outside of the main flow pipe 2, two fixed blocks 11 fixedly connected to the outer wall of one side of the driving block 10, a plurality of sliding rods 12 fixedly connected between the two fixed blocks 11, and a supporting plate 13 slidably sleeved on the outside of the plurality of sliding rods 12. The turntable 6 is rotatably connected to the inside of the supporting plate 13 and is arranged through the supporting plate 13. The supporting plate 13 is a hollow structure.

[0041] When the driving mechanism drives the main pipe 2 to rotate, the driving block 10, the fixing block 11 and the slide bar 12 drive the support plate 13 to perform an orbital motion around the main pipe 2. During this process, the relative position between the branch pipe 3 and the turntable 6 does not change.

[0042] A displacement mechanism, which is installed on the supporting mechanism, is used to drive the positioning mechanism and the fire sprinkler 26 to move. The input end of the fire sprinkler 26 is a threaded structure, and a threaded groove is provided inside the shunt pipe 3, so the fire sprinkler 26 can be screwed into the inside of the shunt pipe 3. The displacement mechanism includes a first transmission shaft 14 rotatably connected to the inside of the driving block 10, a second transmission shaft 15 rotatably connected to the inside of one of the fixed blocks 11, and a reciprocating screw 16 fixedly sleeved on the outside of the second transmission shaft 15, wherein the first transmission shaft 14 can also be directly driven by a motor, that is, one more motor is provided to directly drive the first transmission shaft 14 to rotate forward or reverse. When one more motor is provided, the one-way gear 24 and the inner gear ring 23 can be cancelled. The outsides of the first transmission shaft 14 and the second transmission shaft 15 are fixedly sleeved with bevel gears 17, and the two bevel gears 17 are meshed with each other. The support plate 13 is screwed on the outside of the reciprocating screw 16, and the first transmission shaft 14 is connected to the driving mechanism;

[0043] In this embodiment, two adjacent fire sprinkler heads 26 are spaced apart after installation so as not to affect each other during detection;

[0044] The first transmission shaft 14 is driven to rotate by the driving mechanism, and the second transmission shaft 15 is driven to rotate by the meshing action between the two bevel gears 17, and the reciprocating screw 16 rotates accordingly, thereby driving the support plate 13 to move toward the diversion pipe 3, thereby driving the turntable 6 and the fire sprinkler 26 inside it to move synchronously.

[0045] The linkage mechanism is installed on the supporting mechanism and is used to drive the moving fire sprinkler 26 to rotate so that the fire sprinkler 26 is connected to the shunt pipe 3. The linkage mechanism includes a telescopic shaft 18 rotatably connected to one of the fixed blocks 11, a first gear 19 fixed to the extended end of the telescopic shaft 18, and an outer gear ring 20 fixedly sleeved on the outside of one of the turntables 6. The first gear 19 is meshed with the outer gear ring 20. The bottom ends of the second transmission shaft 15 and the telescopic shaft 18 are both fixedly connected with second gears 21. The two second gears 21 are meshed with each other. The two adjacent turntables 6 are connected by a transmission member 22. The transmission member 22 includes synchronous wheels fixedly sleeved on the outside of the two turntables 6 and synchronous belts connected to the outside of the two synchronous wheels.

[0046] When the second transmission shaft 15 rotates, the telescopic shaft 18 is driven to rotate through the meshing action between the two second gears 21, and the turntable 6 is driven to rotate through the meshing action between the first gear 19 and the outer gear ring 20, so that when the turntable 6 drives the fire sprinkler 26 to rotate and move toward the diversion pipe 3, the threaded connection between the fire sprinkler 26 and the diversion pipe 3 is realized.

[0047] A driving mechanism is installed on the housing 1 and is used to drive the displacement mechanism and the main flow pipe 2 to operate. The driving mechanism includes an inner gear ring 23 fixedly connected to the inner wall of one side of the housing 1, a one-way gear 24 installed outside the first transmission shaft 14, and a motor 25 installed on the outer wall of one side of the housing 1. The output end of the motor 25 is fixedly connected to the other end of the main flow pipe 2.

[0048] When the fire sprinkler 26 located in each turntable 6 inside the top support plate 13 is installed, the main flow pipe 2 is driven to rotate 120° in the forward direction by controlling the motor 25, thereby driving the support plate 13 on the next drive block 10 to face upward. In this process, the one-way gear 24 is driven to rotate through the meshing effect between the inner gear ring 23 and the one-way gear 24, but the first transmission shaft 14 does not rotate therewith. After the support plate 13 on the next drive block 10 faces upward, the staff will install the fire sprinkler in each turntable 6 inside the current support plate 13 in turn, and then control the motor 25 to drive the main flow pipe 2 to rotate 120° in the forward direction, and install the fire sprinkler in each turntable 6 inside the support plate 13 in turn, thereby achieving the effect of quickly installing multiple fire sprinkler 26 to be tested;

[0049] When it is necessary to establish a connection between the fire sprinkler 26 and the shunt pipe 3, the main pipe 2 is driven to rotate 120° in the opposite direction by controlling the motor 25. In this process, the first transmission shaft 14 is driven to rotate through the meshing effect between the one-way gear 24 and the inner gear ring 23, thereby driving the displacement mechanism to operate, driving the support plate 13 and the turntable 6 inside it and the fire sprinkler 26 to move toward the shunt pipe 3, and at the same time cooperating with the linkage mechanism to drive the fire sprinkler 26 to rotate, so that one end of the fire sprinkler 26 is screwed into the inside of the shunt pipe 3, thereby establishing a connection between the fire sprinkler 26 and the shunt pipe 3;

[0050] When the fire sprinkler 26 is inspected, the motor 25 is controlled to stop every time the main flow pipe 2 rotates 120° in the forward direction, thereby realizing the inspection of the fire sprinkler 26 on each support plate 13 in sequence.

[0051] Working principle: When in use, the staff will place all the fire sprinkler heads 26 in the turntable 6 inside the support plate 13 currently located at the top, and drive the limit block 9 to move and fix the fire sprinkler head 26 inside the positioning groove 7, and drive the main flow pipe 2 to rotate 120° in the positive direction by controlling the motor 25, and then drive the support plate 13 on the next drive block 10 to face upward. In this process, the one-way gear 24 is driven to rotate through the meshing effect between the inner gear ring 23 and the one-way gear 24, but the first transmission shaft 14 does not rotate accordingly, and the support plate 13 on the next drive block 10 faces upward. After the fire sprinkler is installed, the staff will install the fire sprinkler heads in turn inside each turntable 6 inside the current support plate 13, and then control the motor 25 to drive the main flow pipe 2 to rotate 120° in the forward direction, and install the fire sprinkler heads in turn inside each turntable 6 inside the support plate 13, thereby achieving the effect of quickly installing multiple fire sprinkler heads 26 to be tested, and then control the motor 25 to drive the main flow pipe 2 to rotate 120° in the reverse direction. In this process, the first transmission shaft 14 is driven to rotate through the meshing effect between the one-way gear 24 and the inner gear ring 23, and then the meshing between the two bevel gears 17 is used to drive the first transmission shaft 14 to rotate. The second transmission shaft 15 is driven to rotate, and the reciprocating screw 16 rotates accordingly, thereby driving the support plate 13 to move toward the direction of the shunt pipe 3, thereby driving the turntable 6 and the fire sprinkler 26 inside it to move synchronously. At the same time, when the second transmission shaft 15 rotates, the telescopic shaft 18 is driven to rotate through the meshing effect between the two second gears 21, and the turntable 6 is driven to rotate through the meshing effect between the first gear 19 and the outer gear ring 20, so that the turntable 6 drives the fire sprinkler 26 to rotate while moving toward the shunt pipe 3, so that the fire sprinkler 26 and the shunt pipe 3 are connected. After all the fire sprinklers 26 are installed and connected to the shunt pipe 3, the main pipe 2 is pressurized and supplied with water through the water supply equipment, and the liquid inside the main pipe 2 is sprayed out through each shunt pipe 3 and each fire sprinkler 26. At the same time, the motor 25 is controlled to drive the main pipe 2 to rotate 120° in the forward direction and pause for a while. The staff observes the downward fire sprinklers 26 in turn to confirm whether each sprinkler is discharging water normally and the water discharge area, thereby achieving the effect of simultaneous observation and detection of multiple fire sprinklers 26, and improving the detection efficiency of the fire sprinklers 26;

[0052] In addition, in order to reduce the loss of water used for detection, a solenoid valve can be installed on the diversion pipe 3. When the fire sprinkler 26 rotates downward, the solenoid valve on the diversion pipe 3 connected to the current fire sprinkler 26 is controlled to open, and the solenoid valves on the other two rows of diversion pipes 3 are in a closed state. When the detection of the current fire sprinkler 26 is completed and turned away, the solenoid valve is controlled to close, and the above operation is repeated to detect each row of fire sprinkler 26 in turn.
