Technical Field

[0001] The utility model relates to the technical field of fire detection, in particular to a portable fire line detection device. Background Art

[0002] Fire lines play a crucial role in ensuring the fire safety of buildings. However, in actual use, various faults such as open circuits, short circuits, poor contacts, and cable aging may occur in fire lines, which seriously affect the normal operation of the fire protection system and pose great potential safety hazards to fire safety.

[0003] At present, the detection work for fire lines faces many challenges, and traditional detection methods have certain drawbacks. For example, when using a line detector for segment-by-segment detection, the handheld operation cannot always adapt the detection device to the line, and it is also difficult to adapt to lines of various thicknesses. Therefore, there is an urgent need to design a portable fire line detection device to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a portable fire line detection device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A portable fire line detection device includes a housing. A connection frame is fixedly installed at the middle of one side of the housing, and a handle rod is fixed at one end of the connection frame. A wire groove is opened at the middle of the other side of the housing. Sliding seats are slidably arranged at the top and bottom of one inner wall of the housing, and an extrusion seat is fitted to one side of each sliding seat. An active frame is fixedly installed on one side of each extrusion seat. A displacement component for adjusting the position of the active frame is arranged on the connection frame and the handle rod. Two ends of the top of each sliding seat are fixedly provided with connecting plates passing through the active frame, and U-shaped frames are fixed at one ends of the connecting plates. Pulleys are rotatably arranged at the ends of the U-shaped frames. A mounting plate is fixed to one side of two of the U-shaped frames, and a detector body is fixedly installed on the mounting plate.

[0007] Further, one side of each sliding seat and one side of each extrusion seat are both designed to be inclined surfaces, a traction groove is opened at the inclined surface of the sliding seat, a traction block inserted into the traction groove is fixedly installed at the inclined surface of the extrusion seat, and the cross sections of the traction block and the traction groove are designed to be T-shaped.

[0008] Further, sliding grooves are opened at the other sides of the sliding seats, and sliding rails passing through the sliding grooves are fixedly installed on one inner wall of the housing.

[0009] Further, the active frame is designed to be "day" shaped.

[0010] Furthermore, the position of the detector body corresponds to the middle position of the pulley.

[0011] Furthermore, the displacement component includes a through hole located at the middle of one side of the handle, the middle of both ends of the connecting frame, and the middle of one side of the housing. A pull rod passing through the through hole is fixedly installed at the middle of one side of the movable frame. One end of the pull rod extends into the interior of the handle and a pressing plate is fixedly installed at one end of the pull rod. A fixing ring is fixed to one side of the outer wall of the pull rod, and a spring is fixedly installed on one side of the fixing ring and one end of the inner wall of the connecting frame.

[0012] Furthermore, a controller and a battery box are fixedly installed on the top and bottom of one side of the housing, respectively. An alarm is installed on the top of the controller, and a storage battery is installed inside the battery box. The storage battery, controller, detector body and alarm are electrically connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the entire device is integrated into the housing, and a handle is fixed to one side of the housing via a connecting frame, making it easy for operators to hold, carry, and move, meeting the requirements for portability. Simultaneously, the displacement component is adjusted via a pull rod, through a hole, and a spring. When the operator holds the handle, they can directly pull the pull rod to quickly adjust the position of the movable frame, thereby controlling the clamping state of the pulleys. When clamping the line, the pulleys can roll along with the line, reducing friction and preventing line deviation. The operation is simple and intuitive, suitable for handheld operation scenarios. Furthermore, when the line is stably clamped between the pulleys, the detector body can accurately align with the line detection point, ensuring the accuracy of the detection data.

[0015] In this invention, when the movable frame moves the extrusion seat, the inclined surface of the extrusion seat pushes the movable seat to slide along the slide rail, thereby changing the distance between the two sets of pulleys. This design enables the device to adapt to fire protection lines of different thicknesses, solving the problem of poor adaptability of traditional testing equipment to line diameter and improving the versatility of the equipment.

[0016] In this invention, the entire device integrates a battery box, a controller, and an alarm, and all components are electrically connected. When the detector detects a circuit fault such as an open circuit or short circuit, the controller can quickly trigger the alarm to promptly remind the operator, thus improving the efficiency of troubleshooting.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5, in the embodiment of the utility model, a portable fire line detection device includes a housing 1. A connection frame 3 is fixedly installed at the middle of one side of the housing 1, and a handle rod 4 is fixed at one end of the connection frame 3. A wire slot 2 is provided at the middle of the other side of the housing 1. Sliding seats 11 are slidably arranged at the top and bottom of one inner wall of the housing 1, and pressing seats 17 are fitted to one side of each sliding seat 11. One side of the sliding seat 11 and one side of the pressing seat 17 are both designed to be inclined surfaces. A traction groove 20 is provided at the inclined surface of the sliding seat 11, and a traction block 19 inserted into the traction groove 20 is fixedly installed at the inclined surface of the pressing seat 17. The cross sections of the traction block 19 and the traction groove 20 are designed to be T-shaped. A same movable frame 10 is fixedly installed on one side of the pressing seat 17. The movable frame 10 is designed to be in the shape of "day". A displacement component for adjusting the position of the movable frame 10 is arranged on the connection frame 3 and the handle rod 4. Two ends of the top of the sliding seat 11 are both fixedly provided with connecting plates 16 passing through the movable frame 10, and a U-shaped frame 24 is fixedly installed at one end of each connecting plate 16. Pulleys 9 are rotatably arranged at the ends of the U-shaped frames 24. A same mounting plate 18 is fixed on one side of two of the U-shaped frames 24, and a detector body 14 is fixedly installed on the mounting plate 18. The position of the detector body 14 corresponds to the middle position of the pulley 9, which is convenient for the operator to hold, carry and move, meeting the requirements of portability. At the same time, the line is stably clamped between the pulleys 9, so that the detector body 14 can accurately align with the line detection point, ensuring the accuracy of the detection data.

[0025] Specifically, sliding grooves 15 are provided on the other side of each sliding seat 11, and sliding rails 12 passing through the sliding grooves 15 are fixedly installed on one inner wall of the housing 1. The movement track of the sliding seat 11 is restricted by the sliding connection between the sliding groove 15 and the sliding rail 12, ensuring its translational stability.

[0026] Specifically, the displacement component includes through holes 21 provided at the middle of one side of the handle rod 4, at the middle of both ends of the connection frame 3 and at the middle of one side of the housing 1. A pull rod 5 passing through the through hole 21 is fixedly installed at the middle of one side of the movable frame 10. One end of the pull rod 5 extends into the handle rod 4, and a pressing plate 6 is fixedly installed at one end of the pull rod 5. A fixed ring 22 is fixed on one outer wall side of the pull rod 5, and a spring 13 is fixedly installed between one side of the fixed ring 22 and the inner wall of one end of the connection frame 3. Press the pressing plate 6 in the displacement component, pull the pull rod 5 to move in the through hole 21,带动 the movable frame 10 to move,从而带动 the pressing seat 17 to move synchronously. The pressing seat 17 presses the sliding seat 11 to slide along the sliding rail 12. At the same time, the U-shaped frame 24 is带动 to move synchronously through the connecting plate 16, so that the two groups of pulleys 9 approach each other, facilitating the clamping of the fire line.

[0027] Specifically, a controller 7 and a battery box 23 are fixedly installed on the top and bottom of one side of the housing 1, respectively. An alarm 8 is installed on the top of the controller 7, and a storage battery is installed inside the battery box 23. The storage battery, controller 7, detector body 14 and alarm 8 are electrically connected. When the detector body 14 detects a circuit fault such as an open circuit or short circuit, the controller 7 can quickly trigger the alarm 8 to alert the operator in time, thus improving the efficiency of fault diagnosis.

[0028] The working principle of this utility model is as follows: When in use, the operator holds the handle 4 and inserts the fire protection line through the wire groove 2 into the housing 1, so that it is between the two sets of pulleys 9. Pressing the pressing plate 6 in the displacement component, pulling the pull rod 5 to move in the through hole 21, driving the movable frame 10 to move, thereby driving the pressing seat 17 to move synchronously. The inclined surface of the pressing seat 17 contacts the inclined surface of the movable seat 11. Due to the cooperation of the inclined surfaces of the two, and the traction block 19 on the pressing seat 17 is inserted into the traction groove 20 of the movable seat 11, the movable seat 11 will be pushed to slide along the slide rail 12. When the movable seat 11 moves, the U-shaped frame 24 is driven to move through the connecting plate 16, so that the two sets of pulleys 9 come closer to each other and clamp the fire protection line. At this time, the detector body 14 installed on the mounting plate 18 corresponds to the line and detects the line.

[0029] If a fault is found in the circuit during the detection process, the detector body 14 will transmit a signal to the controller 7, and the controller 7 will control the alarm 8 to issue an alarm.

[0030] After the test is completed, when the pull rod 5 is released, the movable frame 10 returns to its original position under the action of the spring 13, the pressing seat 17 no longer presses the movable seat 11, the movable seat 11 drives the pulley 9 to return to its original position, and the circuit is released.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
