Description

Technical Field

[0001] This application relates to the field of fire protection equipment technology, and in particular to a testing device for fire protection power supply and distribution systems. Background Technology

[0002] Fire protection power supply and distribution testing devices are specialized equipment used to test and evaluate the performance, safety, and reliability of fire protection power supply and distribution systems. These devices can monitor various parameters of the fire protection power supply and distribution system in real time, such as voltage, current, frequency, and grounding resistance, and issue alarms promptly when abnormalities are detected to ensure that fire protection equipment can be powered normally and function properly in emergencies.

[0003] Common testing equipment includes leakage current detectors, which measure the leakage current value of the equipment by measuring the positive and negative terminals to assess the safety performance of the equipment. Since the positive and negative wires need to be rolled up and stored after each test, during use, the wires may become tangled, which takes time to roll up the wires. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide a fire protection power supply and distribution system testing device to solve the above-mentioned technical problems.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: a fire protection power supply and distribution system testing device, including testing equipment and a positive detection line and a negative detection line fixedly connected to the testing equipment, wherein both the positive detection line and the negative detection line are provided with a winding device for winding the wire.

[0006] By adopting the above technical solution, when using the testing equipment, the positive and negative test lines are pulled to test the equipment. After the test is completed, you only need to let go, and the winding device can pull the wires to retract the positive and negative test lines.

[0007] Furthermore, the winding device includes a winding sleeve and a winding shaft rotatably connected in the middle of the winding sleeve. Both the upper and lower sides of the winding shaft are provided with spiral springs. The inner side of the spiral spring is fixedly connected to the winding shaft, and the outer side is fixedly connected to the winding sleeve. The positive electrode detection line and the negative electrode detection line both pass through the winding sleeve and are respectively wound on the winding shaft.

[0008] By adopting the above technical solution, when the positive and negative detection lines are pulled, the winding shaft will rotate in the winding sleeve, pulling the detection lines. After the detection is completed, when the positive and negative detection lines are released, the torque of the spiral spring will cause the winding shaft to rotate and rewind, thereby allowing the detection lines to be recovered.

[0009] Furthermore, the take-up sleeve is fixedly connected to the testing equipment.

[0010] By adopting the above technical solutions, the integration of the testing equipment and the winding device can be improved.

[0011] Furthermore, a temporary fixing device is provided on the winding sleeve.

[0012] By adopting the above technical solution, considering that the detection equipment needs to be used continuously in some cases, the winding device may affect the detection work. Therefore, this application also provides a temporary fixing device to solve this problem.

[0013] Furthermore, the temporary fixing device includes a connecting frame fixedly connected to the upper end of the take-up sleeve, a plug-in post vertically inserted into the connecting frame, a plug-in groove opened on the take-up sleeve, the plug-in groove extending to the upper end of the take-up shaft, a flange fixedly provided on the plug-in post, and a matching groove opened in the plug-in groove.

[0014] By adopting the above technical solution, when the take-up is not required, after pulling the positive and negative detection lines, the plug is inserted into the plug slot. At this time, the flange and groove will restrict the rotation of the take-up shaft, thereby temporarily fixing it.

[0015] Furthermore, a support bracket is provided at the bottom of the testing device, and the support bracket is fixedly connected to the bottom of the testing device.

[0016] Furthermore, the bottom of the support bracket is provided with an anti-slip pad for preventing slippage, and the anti-slip pad has anti-slip patterns.

[0017] By adopting the above technical solution and installing anti-slip pads under the support bracket, the detection equipment is prevented from moving when the positive and negative detection lines are pulled.

[0018] Furthermore, the anti-slip mat is made of flexible rubber.

[0019] In summary, this application offers the following beneficial technical effects: When using the testing equipment, users simply need to pull the testing cable for connection and testing. After testing, the winding device automatically pulls the cable, allowing for easy retraction. This design simplifies the operation process and reduces the time and effort users spend on cable management. The winding device prevents the testing cable from scattering on the ground, reducing tripping hazards. Simultaneously, the neatly wound testing cable reduces the risk of damage caused by external pulling, further improving the safety of the testing process. The winding device protects the testing cable from prolonged exposure and external pulling, thus extending its service life. This not only reduces maintenance costs but also ensures the continuity and reliability of testing operations. Attached Figure Description

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] Example, refer to Figure 1 , Figure 2 as well as Figure 3 A fire protection power supply and distribution system testing device includes a testing unit and two positive and negative testing wires 21 and 22, respectively fixedly connected to the testing unit 1. To improve ease of use and efficiency, both testing wires are equipped with automatic winding devices. During operation, workers simply pull the positive and negative testing wires 21 and 22 to easily extend them to the equipment to be tested. Once the testing task is completed, no additional winding steps are required; simply releasing the wires activates the built-in winding device, automatically pulling and winding the wires so that the positive and negative testing wires 21 and 22 can be quickly and neatly retracted to their initial state, saving space and improving work efficiency.

[0026] In this embodiment, the winding device includes a winding sleeve 2 and a winding shaft 23 rotatably connected to the middle of the winding sleeve 2. Both the upper and lower sides of the winding shaft 23 are provided with spiral springs 26. The inner side of the spiral springs 26 is fixedly connected to the winding shaft 23, and the outer side is fixedly connected to the winding sleeve 2. The positive electrode detection line 21 and the negative electrode detection line 33 both pass through the winding sleeve 2 and are respectively wound around the winding shaft 23. When the positive electrode detection line 21 and the negative electrode detection line 22 are pulled, the winding shaft 23 will rotate within the winding sleeve 2, pulling the detection lines. After the detection is completed, when the positive electrode detection line 21 and the negative electrode detection line 22 are released, the torque of the spiral springs 26 will cause the winding shaft 23 to rotate and wind up, thereby recovering the detection lines.

[0027] In this embodiment, the take-up sleeve 2 is fixedly connected to the detection device 1, thereby improving the integration of the detection device 1 and the take-up device.

[0028] In this embodiment, a temporary fixing device is provided on the winding sleeve 2. Considering that the detection device 1 needs to be used continuously in some cases, the winding device may affect the detection work. Therefore, this application also provides a temporary fixing device to solve this problem.

[0029] In this embodiment, the temporary fixing device includes a connecting frame 4 fixedly connected to the upper end of the take-up sleeve 2. A plug post 41 is vertically inserted into the connecting frame 4. The take-up sleeve 2 has a plug groove 24 that extends to the upper end of the take-up shaft 23. A flange 42 is fixedly provided on the plug post 41. A matching groove 25 is provided in the plug groove 24. When take-up is not required, after pulling the positive detection line 21 and the negative detection line 22, the plug post 41 is inserted into the plug groove 24. At this time, the flange 42 and the groove 25 will restrict the rotation of the take-up shaft 23, thereby temporarily fixing it.

[0030] In this embodiment, a support bracket 3 is provided at the bottom of the testing device 1, and the support bracket 3 is fixedly connected to the bottom of the testing device 1. An anti-slip pad 31 is provided at the bottom of the support bracket 3 for anti-slip purposes, and anti-slip textures 32 are formed on the anti-slip pad 31. By providing the anti-slip pad 31 under the support bracket 3, the testing device 1 is prevented from moving when the positive electrode detection line 21 and the negative electrode detection line 22 are pulled. The anti-slip pad 31 is made of flexible rubber.

[0031] Specific implementation process: The positive and negative detection wires pass through the take-up sleeve 2 and are wound around their respective take-up shafts 23. When the user pulls the detection wires, the take-up shaft 23 will rotate inside the take-up sleeve 2, releasing the wires; and when the detection task is completed, simply release the detection wires, and the torque of the spiral spring 26 will drive the take-up shaft 23 to rotate in the opposite direction, automatically retracting the wires.

[0032] To enhance the overall integrity of the inspection device 1 and the winding device, the winding sleeve 2 is directly and fixedly connected to the inspection device 1. Furthermore, considering that the inspection device 1 may require continuous use in certain inspection scenarios, and the winding device might interfere with the inspection work, the device is also equipped with a temporary fixing device. This device consists of a connecting frame 4, a plug-in post 41, and a flange 42. The connecting frame 4 is fixedly connected to the upper end of the winding sleeve 2. The plug-in post 41 can be vertically inserted into the connecting frame 4, and the winding sleeve 2 has a plug-in slot 24 that matches the plug-in post 41. The plug-in post 41 is fixed with a flange 42, and the plug-in slot 24 has a corresponding groove 25. When the wire winding is not required, the user can insert the plug-in post 41 into the plug-in slot 24. At this time, the flange 42 and the groove 25 will jointly restrict the rotation of the winding shaft 23, achieving temporary fixing.

[0033] To ensure the stability of the testing equipment 1 during use, a support bracket 3 is installed at the bottom of the equipment, which is also fixedly connected to the testing equipment 1. The bottom of the support bracket 3 is equipped with an anti-slip pad 31, which is made of flexible rubber and engraved with anti-slip texture 32, designed to prevent the testing equipment 1 from moving when the testing line is pulled.

[0034] In summary, this fire protection power supply and distribution system testing device is not only compact and comprehensive in function, but also user-friendly in design, significantly improving the efficiency and safety of fire protection power supply and distribution system testing. Users can easily deploy and retract the testing cable and secure the equipment with simple operation, allowing them to focus more on the testing task itself.

[0035] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
