Description

Technical Field

[0001] The present application relates to the field of weak current technology for fire protection, and in particular to a weak current safety detection device for fire protection engineering. Background Art

[0002] As the name suggests, fire protection weak current refers to the weak current systems and equipment used in fire protection systems and fire protection projects. It is generally composed of various electronic sensors, circuit boards, IC modules, etc. combined into professional industrial computers. It detects the occurrence of fire through information provided by smoke and temperature probes, and the computer system analyzes it and then outputs a control electrical signal. The electrical signal then drives the solenoid valve and other electronic control components on the release gate of the professional fire extinguishing agent container to execute the action, and the fire extinguishing agent is released at the fire scene.

[0003] For example, the publication number "CN213210332U" discloses "a weak-current safety detection device for fire protection engineering, including an electric tester, wherein the upper outer surface of the electric tester is provided with a non-contact lamp... The elastic rubber sleeve is a truncated cone-shaped tubular structure". The insulating cover is provided, and when in use, it is rotated to be removed. First, check whether there is a safety resistor in the electric tester, and then visually check whether the electric tester is damaged, damp or water-logged. It can be used only after passing the inspection. After use, the electric tester and the insulating cover are tightly connected through the connecting thread. The insulating cover can effectively protect the internal sensor head, prevent water vapor in the air from entering the electric tester, reduce the threat of electric shock, and improve the safety factor of use.

[0004] Regarding the above-mentioned related technologies, the inventor believes that the connection between the insulating sleeve and the tester in the above device is relatively unstable. When placed in the tool bag, the staff shakes it back and forth, and the insulating sleeve is more likely to fall off, thereby losing its effect and increasing safety hazards. Therefore, a fire engineering weak current safety detection device is proposed to solve the above problems.

[0005] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0020] The following is combined with Figure 1-4 This application is described in further detail.

[0021] The embodiment of the present application discloses a weak current safety detection device for fire protection engineering. Figure 1-4 A fire protection engineering weak current safety detection device includes a detection shell 1, the outer wall of the detection shell 1 is provided with an internal sensing head 4 for detection, and the weak current of the fire protection engineering can be tested through the internal sensing head 4, so that it can be displayed on the detection shell 1. Two T-shaped slots 2 are provided on the outer walls of the detection shell 1 on both sides, and the outer wall of the detection shell 1 is provided with an insulating sleeve 3, and two sliders 14 are fixedly connected to the inner walls of the insulating sleeve 3 on both sides, and the two sliders 14 are slidably connected to the two T-shaped slots 2. The two sliders 14 on the insulating sleeve 3 are slidably connected to the two T-shaped slots 2 on the detection shell 1, so that the insulating sleeve 3 can slide back and forth on the detection shell 1, and then the insulating sleeve 3 can shrink back and forth, so that it can penetrate the internal sensing head 4. For protection, when in working state, the insulating sleeve 3 is retracted to the inside of the detection shell 1, thereby leaking the internal sensing head 4, which is convenient for it to perform detection work; when in non-working state, the insulating sleeve 3 is moved to the outside of the detection shell 1 to shield and protect the internal sensing head 4, and at the same time, the slider 14 is T-shaped and slidably connected to the T-slot 2 to avoid separation between the insulating sleeve 3 and the detection shell 1, and the outer wall of the insulating sleeve 3 is slidably connected with the lower protective sleeve 5, which is slidably connected to the insulating sleeve 3 through the lower protective sleeve 5, so that it is convenient to seal the opening of the insulating sleeve 3, thereby facilitating the improvement of the shielding and protection effect of the internal sensing head 4, and the outer wall of the lower protective sleeve 5 is provided with a fixing component, through which the lower protective sleeve 5 can be fixed on the insulating sleeve 3.

[0022] The outer wall of the insulating sleeve 3 is fixedly connected to a spur rack 8, and the outer wall of the detection shell 1 on one side of the spur rack 8 is rotatably connected to a gear 10, and the gear 10 is meshed with the spur rack 8. The outer wall of the gear 10 is fixedly connected to a turning handle 11. When a person turns the turning handle 11, the turning handle 11 drives the gear 10 to rotate, and the meshing between the gear 10 and the spur rack 8 makes it convenient for the gear 10 to drive the spur rack 8 to move back and forth, and then the spur rack 8 drives the insulating sleeve 3 to extend and retract back and forth.

[0023] The fixing assembly includes a fixing hole 6, which is opened on the outer wall of one end of the lower protective cover 5. The outer wall of the insulating cover 3 is provided with a fixing bolt 7 adapted thereto. By sliding the lower protective cover 5 onto the insulating cover 3, the fixing hole 6 corresponds to the fixing bolt 7. By rotating the fixing bolt 7, the fixing bolt 7 is threadedly connected to the fixing hole 6 to complete the fixation of the lower protective cover 5.

[0024] The detection shell 1 has two threaded holes 9 on its side outer wall, the insulating sleeve 3 has a docking hole 12 on its outer wall, and a fixing screw 13 is provided on one side of the threaded hole 9, and the fixing screw 13 is threadedly connected to the two threaded holes 9. When the insulating sleeve 3 blocks and protects the internal sensing head 4, the docking hole 12 is connected to the threaded hole 9 on the outside, so that the fixing screw 13 is passed through the docking hole 12 and threadedly connected to the threaded hole 9 to complete the fixation of the insulating sleeve 3 and prevent it from sliding. When the insulating sleeve 3 does not block and protect the internal sensing head 4, the docking hole 12 corresponds to the inner threaded hole 9, so that the fixing screw 13 is passed through the docking hole 12 and threadedly connected to the threaded hole 9 to fix the insulating sleeve 3.

[0025] The outer wall of the detection shell 1 is provided with a display component 15 for sensing. The display component 15 includes a non-contact light, a contact indicator light, a network cable detection end and an LED night vision screen. When in use, the network cable is directly connected to the detection end at the rear end of the tester, and the finger is pressed on the touch gear to determine whether the cable is energized by observing the indicator light. When the network cable detection end is connected to a charged object, the current forms a power circuit through the charged object, the sensing head, the human body and the earth. As long as the potential difference between the charged object and the earth exceeds 60V, the connection indicator light on the detection shell 1 will light up, and the front LED night vision display screen will display the specific voltage value.

[0026] The implementation principle of a weak current safety detection device for fire protection engineering in the embodiment of the present application is as follows: first, when the detection shell 1 is not in use, the worker rotates the handle 11, and the handle 11 drives the gear 10 to rotate, thereby making the gear 10 mesh with the spur rack 8, so that the gear 10 drives the spur rack 8 to move, and then drives the insulating sleeve 3 to move along the trajectory of the T-slot 2, so that the docking hole 12 on the insulating sleeve 3 is docked with the threaded hole 9 at the end of the detection shell 1, and then the fixing screw 13 is threadedly connected with the docking hole 12 through the fixing screw 13, and the insulating sleeve 3 is fixed on the detection shell 1, completing the shielding of the internal sensing head 4 by the insulating sleeve 3, and then the fixing hole 6 is connected with the groove opened by the insulating sleeve 3, and the fixing hole 6 is pushed to block the opening of the insulating sleeve 3, so that the fixing hole 6 is connected with the hole position on the insulating sleeve 3, and then the fixing bolt 7 is rotated to fix the fixing bolt 7. The bolt 7 is threadedly connected to the fixing hole 6 to fix the lower protective cover 5, thereby completing the protection of the internal sensing head 4. At the same time, when the detection shell 1 is used to perform weak current engineering machinery detection, the fixing hole 6 and the insulating cover 3 are separated by loosening the fixing bolt 7 to fix the lower protective cover 5, and then the fixing screw 13 is rotated to separate the fixing screw 13 from the docking hole 12, thereby loosening the fixation of the insulating cover 3, and then rotating the handle 11 to make the handle 11 drive the gear 10 to rotate, and then the gear 10 drives the spur rack 8 to move, so that it drives the insulating cover 3 to shrink, so that the internal sensing head 4 is exposed to the air, which is convenient for the internal sensing head 4 to work. When the docking hole 12 on the insulating cover 3 corresponds to the threaded hole 9 on the inner side, the fixing screw 13 is passed through the docking hole 12 and connected to the threaded hole 9 for fixing, thereby preventing the insulating cover 3 from sliding and affecting the work when the detection shell 1 is working.
