[0002] The main function of the leakage detection device for fire-fighting facilities is to ensure the safety of rescue personnel. During the fire-fighting and rescue process, after the electrical circuit insulation is damaged, a leakage phenomenon may occur, which will not only cause local substances to be charged, but also may bring serious or fatal electric shock hazards to rescue personnel. The leakage detection device can remind rescue personnel in the form of sound, light, etc. before they come into contact with the leakage object, so as to effectively avoid the occurrence of electric shock accidents and ensure the safety of rescue personnel.

[0003] After retrieving the existing published literature, the patent with the patent publication number CN109991506A discloses a detection device for a leakage detection device of fire-fighting facilities. In this detection device, a primary coil is wound around the magnetic conduction column in the middle of the mountain-shaped magnetic core, a secondary coil is wound around the magnetic conduction column beside the mountain-shaped magnetic core, and a rectangular movable magnetic conduction block is placed at the top ends of the three columns above the mountain-shaped magnetic core. The magnetic conduction block is connected to the movement control device. Through this invention, the detection of leakage detection devices with different leakage detection values can be realized by the same device. However, this detection device still has the following defects.

[0004] During the fire-fighting and rescue process, a leakage detection device is needed to detect some electrical parts with leakage. After knowing the existence of the leakage problem, when carrying out the rescue, the leakage problem will be dealt with first, so it is necessary to ensure the personal safety of rescue personnel. However, during the fire-fighting and rescue, the space at the rescue site is narrow, making it difficult for the leakage detection device to be adjusted in multiple directions according to the actual situation, which results in poor applicability of the leakage detection adjustment. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides the following technical solution: A leakage detection device for fire-fighting facilities, including a fixed frame, a vertical electric cylinder, and a connecting plate. The vertical electric cylinder is fixed on the upper surface of the fixed frame, the connecting plate is fixedly installed at the output end of the vertical electric cylinder, and a two-way leakage detection adjustment mechanism is provided at the bottom end of the connecting plate; the two-way leakage detection adjustment mechanism includes a connecting frame fixedly arranged at the bottom end of the connecting plate, and a transverse rod is fixedly connected to the inner wall of the connecting frame. Two socket sliders are slidably connected to the outer wall of the transverse rod. A vertical rod is slidably connected to the inner wall of each socket slider. The top end of the vertical rod is fixedly connected to a guiding vertical frame, and the socket slider and the guiding vertical frame are slidably connected to each other.

[0006] One side of the guiding vertical frame is slidably connected with a linkage sleeve plate, and a leakage detection end rod is installed inside the linkage sleeve plate. The inner wall of the fixed frame is rotatably connected with a bidirectional screw rod, and two threaded sleeve blocks are threadedly connected to the outer wall of the bidirectional screw rod. Both of the two threaded sleeve blocks are slidably connected to the fixed frame. The threaded sleeve block is fixedly connected to the guiding vertical frame. One end of the fixed frame is fixedly installed with an adjusting motor, which is used to drive the bidirectional screw rod to rotate. The two threads on the outer wall of the bidirectional screw rod are opposite and symmetrically arranged; a displacement leakage detection mechanism is arranged at the top of the outer wall of the leakage detection end rod; a rotation detection component is arranged on one side of the outer wall of the leakage detection end rod.

[0007] Preferably, both of the two socket sliders are slidably connected to the connecting frame, and there is a gap between the connecting frame and the fixed frame; the outer walls of the two socket sliders and the inner wall of the connecting frame are both smooth surfaces.

The socket slider is fixedly connected to the linkage sleeve plate, and the cross-sectional shape of the linkage sleeve plate is rectangular.

[0008] When the present technology is in use, the vertical electric cylinder pushes the connecting plate upward, the connecting frame makes the cross bar move upward, at the same time the socket slider slides upward along the outer wall of the vertical rod, the socket slider drives the linkage sleeve plate to move upward, and the two leakage detection end rods are synchronously moved upward. The adjusting motor drives the bidirectional screw rod to rotate, and the bidirectional screw rod drives the two threaded sleeve blocks to move away from each other under the action of the thread driving force. One threaded sleeve block moves leftward, and the other threaded sleeve block moves rightward. The guiding vertical frame drives the socket slider to move leftward, and at the same time the socket slider slides leftward along the inner wall of the connecting frame, and the linkage sleeve plate drives the leakage detection end rod to move leftward. The rotating shaft drives the conductive terminal to move leftward, the conductive terminal drives the contact terminal to move leftward, and the other contact terminal moves rightward.

[0009] Preferably, a displacement leakage detection mechanism is arranged at the top of the outer wall of the leakage detection end rod;

[0010] The displacement leakage detection mechanism includes an insulating block fixedly arranged at the top of the outer wall of the leakage detection end rod, and a horizontal electric cylinder is fixedly connected to one side of the insulating block, and a push rod is fixedly installed at the output end of the horizontal electric cylinder.

[0011] One end of the push rod is fixedly connected with a rack, and a conductive terminal is rotatably connected inside the leakage detection end rod. One end of the conductive terminal is fixedly connected with a contact terminal. A rotating shaft is fixedly installed at the top end of the conductive terminal. The rotating shaft is rotatably connected with the leakage detection end rod. An angle sensor is fixedly installed at the top end of the rotating shaft. A rotatably connected gear is arranged above the leakage detection end rod, and the gear is fixedly connected with the rotating shaft. A support block is installed on one side of the angle sensor, and both the leakage detection end rod and the angle sensor are fixedly connected with the support block.

[0012] When the present technology is in use, by starting two horizontal electric cylinders, the insulating block supports the horizontal electric cylinders, the horizontal electric cylinders push the push rod to move rightward, the rack drives the gear to rotate counterclockwise, the rotating shaft rotates counterclockwise inside the leakage detection end rod, and at the same time the rotating shaft rotates counterclockwise at the output end of the angle sensor, and the support block supports the angle sensor. The conductive terminal drives the contact terminal to rotate counterclockwise, and the other contact terminal rotates clockwise.

[0013] Preferably, the rotation detection assembly includes a conducting wire harness arranged on one side of the outer wall of the leakage detection end rod; a rotating disk is fixedly installed on one side of the fixed frame, and a rotating rod is fixedly connected to one end of the rotating disk. A rotating motor is fixedly installed at one end of the rotating rod, and a sleeve grip is fixedly installed on the outer wall of the rotating motor.

The vertical cross-sectional shapes of the two limiting rings are both circular rings, and the two conducting wire harnesses are symmetrically arranged with respect to the connecting wire harness.

[0015] When the present technology is in use, after turning on the leakage detector, the rotating motor drives the rotating rod to rotate, and the rotating disk drives the fixed frame to rotate, so that the fixed frame can perform vertical rotation operation. The two contact terminals conduct electricity to the two conductive terminals, and the two conductive terminals conduct electricity to the conducting wire. The leakage detection end rod conducts electricity to the conducting wire harness, the conducting wire harness conducts electricity to the connecting wire harness, and the leakage value can be viewed on the display screen of the leakage detector.

[0016] The technical effects and advantages of the present invention:

[0017] 1. Through the two-way leakage detection and adjustment mechanism of the present invention, the vertical electric cylinder pushes the connecting plate upward. The connecting plate drives the connecting frame upward. The transverse rod drives the two socket sliders to move upward synchronously. At the same time, the socket sliders slide upward along the outer wall of the vertical rod. The adjustment motor drives the bidirectional screw to rotate. The bidirectional screw drives the two threaded sleeve blocks to move away from each other under the action of the threaded driving force. The threaded sleeve block drives the guiding vertical frame to move leftward. The socket slider slides leftward along the inner wall of the connecting frame. The conductive terminal drives the contact terminal to move leftward, and the other contact terminal moves rightward. This can make the two contact terminals be vertically adjusted and the horizontal distance between the two contact terminals be adjusted. In this way, in the state of a narrow rescue detection space, multi-directional adjustment can be realized according to the actual situation, which makes the applicability of the leakage detection adjustment wider.

[0018] 2. The present invention adopts a variable-position leakage detection mechanism. The leakage detection end rod supports the insulating block. The transverse electric cylinder pushes the push rod rightward. The push rod drives the rack rightward. The gear drives the rotating shaft to rotate counterclockwise. The rotating shaft rotates counterclockwise inside the leakage detection end rod. The conductive terminal drives the contact terminal to rotate counterclockwise, and the other contact terminal rotates clockwise. The two contact terminals are horizontally rotated and adjusted, and multi-directional adjustment can be realized according to the actual situation, which makes the applicability of the leakage detection adjustment wider.

[0019] 3. The present invention utilizes a rotation detection component. The rotation motor drives the rotating rod to rotate. The rotating rod drives the rotating disk to rotate. The rotating disk drives the fixed frame to rotate. In this way, the fixed frame can realize vertical rotation operation. When the two contact terminals are butted at the position of the fire-fighting facilities, the two contact terminals conduct electricity to the two conductive terminals, the two conductive terminals conduct electricity to the conductive wire, the conductive wire conducts electricity to the leakage detection end rod, and the conducting wire harness conducts electricity to the connecting wire harness. This makes the applicability of the leakage detection adjustment wider.

[0020] Due to the mutual influence of the above multiple functions, first, the rotating disk drives the fixed frame to rotate, so that the fixed frame can realize vertical rotation operation, and the rotation operation is realized through the two contact terminals. Secondly, the two contact terminals are vertically adjusted and the horizontal distance between the two contact terminals is adjusted. Finally, the two contact terminals are horizontally rotated and adjusted. In summary, in the state of a narrow rescue detection space, multi-directional adjustment, horizontal rotation adjustment and vertical rotation can be realized according to the actual situation, making the applicability of the leakage detection adjustment wider.

The rack 17 is slidably connected to the leakage detection end rod 10, and both the conductive terminal 18 and the contact terminal 19 are made of copper material.

[0037] In this technical solution, as shown in the attached Figure 7 -attached Figure 8 figures, the rotation detection assembly includes a conduction wire harness 30 provided on one side of the outer wall of the leakage detection end rod 10; a rotating disk 25 is fixedly installed on one side of the fixed frame 1, and one end of the rotating disk 25 is fixedly connected to a rotating rod 26. One end of the rotating rod 26 is fixedly installed with a rotating motor 27, and a socket grip cylinder 28 is fixedly installed on the outer wall of the rotating motor 27.

[0038] Two limiting rings 29 are fixedly connected to the outer wall of the socket grip cylinder 28. A connection wire harness 31 is fixedly installed between the two conduction wire harnesses 30. One end of the connection wire harness 31 is fixedly installed with a leakage detector 32; a storage battery 33 is fixedly connected to the lower surface of the leakage detector 32, and a hanging rope 34 is fixedly connected to the upper surface of the leakage detector 32. The rotating motor 27 is used to drive the rotating rod 26 to rotate, and the center point of the rotating rod 26 and the center point of the rotating disk 25 are on the same horizontal line. The vertical cross-sectional shapes of the two limiting rings 29 are both circular rings, and the two conduction wire harnesses 30 are symmetrically arranged with respect to the connection wire harness 31.

[0039] The working principle of the leakage detection device for the fire-fighting facilities of the present invention is as follows:

[0040] Step 1: During rotation detection, the hand is held on the outer wall of the socket grip cylinder 28. At the same time, the two limiting rings 29 can limit and protect the hand. At the same time, the storage battery 33 supplies power to the leakage detector 32, and the hanging rope 34 is hung around the user's neck. In this way, after the leakage detector 32 is turned on and the rotating motor 27 is started, the rotating motor 27 drives the rotating rod 26 to rotate, the rotating rod 26 drives the rotating disk 25 to rotate, and the rotating disk 25 drives the fixed frame 1 to rotate. In this way, the fixed frame 1 can achieve vertical rotation operation.

[0041] Step 2: When performing two-way leakage detection and adjustment, start the vertical cylinder 2. The vertical cylinder 2 pushes the connecting plate 3 upward. The connecting plate 3 drives the connecting frame 4 upward. The connecting frame 4 causes the cross bar 5 to move upward. The cross bar 5 drives the two socket sliders 6 to move upward synchronously. At the same time, the socket sliders 6 slide upward along the outer wall of the vertical rod 7 and slide upward along the inner wall of the vertical rod 7. And the socket sliders 6 drive the linkage sleeve plate 9 upward. The linkage sleeve plate 9 drives the leakage detection end rod 10 upward. The two leakage detection end rods 10 move upward synchronously. At the same time, start the adjustment motor 13. The adjustment motor 13 drives the bidirectional screw 11 to rotate. The bidirectional screw 11 drives the two threaded sleeve blocks 12 to move away from each other under the action of the threaded driving force. One threaded sleeve block 12 moves leftward, and the other threaded sleeve block 12 moves rightward. The threaded sleeve block 12 drives the guiding vertical frame 8 to move leftward. The guiding vertical frame 8 drives the socket slider 6 to move leftward. The socket slider 6 slides leftward along the outer wall of the cross bar 5. At the same time, the socket slider 6 slides leftward along the inner wall of the connecting frame 4. In this way, the vertical rod 7 drives the linkage sleeve plate 9 to move leftward. The linkage sleeve plate 9 drives the leakage detection end rod 10 to move leftward.

[0042] At the same time, the leakage detection end rod 10 drives the rotating shaft 20 to move leftward. The rotating shaft 20 drives the conductive terminal 18 to move leftward. The conductive terminal 18 drives the contact terminal 19 to move leftward. The other contact terminal 19 moves rightward. It can make the two contact terminals 19 perform vertical adjustment and horizontal distance adjustment.

[0043] Step 3: When performing variable-position leakage detection, start the two horizontal cylinders 14. The leakage detection end rod 10 supports the insulating block 15. The insulating block 15 supports the horizontal cylinder 14. The horizontal cylinder 14 pushes the push rod 16 to move rightward. The push rod 16 drives the rack 17 to move rightward. The rack 17 drives the gear 23 to rotate counterclockwise. The gear 23 drives the rotating shaft 20 to rotate counterclockwise. The rotating shaft 20 rotates counterclockwise inside the leakage detection end rod 10. The rotating shaft 20 drives the conductive terminal 18 to rotate counterclockwise. At the same time, the rotating shaft 20 rotates counterclockwise at the output end of the angle sensor 21. The leakage detection end rod 10 provides a supporting force for the support block 22. The support block 22 supports the angle sensor 21. The conductive terminal 18 drives the contact terminal 19 to rotate counterclockwise. The other contact terminal 19 rotates clockwise. In this way, the two contact terminals 19 perform horizontal rotation adjustment.

[0044] Step 4: During the leakage display detection, then dock the two contact terminals 19 at the position of the fire-fighting facilities. Then, the two contact terminals 19 conduct electricity to the two conductive terminals 18, and the two conductive terminals 18 conduct electricity to the conductive wire 24. The conductive wire 24 conducts electricity to the leakage detection end rod 10, the leakage detection end rod 10 conducts electricity to the conduction wire harness 30, the conduction wire harness 30 conducts electricity to the connection wire harness 31, and the connection wire harness 31 conducts electricity to the leakage detector 32. In this way, the display screen on the leakage detector 32 can view the leakage value. If there is a leakage value, it means that there is a leakage problem with the fire-fighting facilities. If there is no leakage problem, the fire-fighting facilities are in a qualified state.

Conventional equipment can be used. In this technical solution, since the electrical control components not mentioned belong to the prior art, they are not shown in the figure and will not be described here either.

[0046] The above are only the preferred embodiments of the present invention and are not used to limit the present invention.
