Description

Technical Field

[0001] The utility model relates to the technical field of leakage detection, in particular to a fire protection leakage detection device for electrical equipment. Background Art

[0002] During construction projects, it is necessary to conduct fire leakage detection on electrical equipment. There are many types of leakage detection devices, including leakage detectors. Leakage detectors refer to equipment used to detect leakage phenomena. They can detect the operating current of current-type electric shock protectors and detect unbalanced leakage currents that are less than the operating current of current-type electric shock protectors.

[0003] After searching, the patent with announcement number CN215375728U discloses a fire leakage detection device for electrical equipment, which solves the problem that the leakage detector in the prior art is directly used by manually holding the probe to touch the part to be detected. Since this traditional method makes the user close to the area to be detected, it is easy to get an electric shock accident. A fire leakage detection device for electrical equipment includes a base, a detector body is fixedly connected to one side of the top of the base, and a detection line is fixedly connected to one side of the detector body.

[0004] Although the fire protection leakage detection device for electrical equipment mentioned above improves the safety of the leakage detection device when in use, the adjustment process of the probe is relatively cumbersome, inconvenient to use, and it is not convenient to move the entire device to perform leakage detection in a larger area.

[0005] In view of the above problems, the present utility model document proposes a fire protection leakage detection device for electrical equipment. Utility Model Content

[0006] The utility model provides a fire protection leakage detection device for electrical equipment, which solves the shortcomings of the prior art that the adjustment process of the probe is complicated, the use is inconvenient, and it is inconvenient to move the entire device to perform leakage detection in a larger area.

[0007] The utility model provides the following technical solutions:

[0008] A fire protection leakage detection device for electrical equipment, comprising:

[0009] A hollow tube, a leakage sensor is fixedly installed at the tube mouth at the top of the hollow tube, a plurality of warning lights are fixedly installed in a ring array at the upper end of the outer wall of the hollow tube, and the plurality of warning lights are electrically connected to the leakage sensor through wires, and a switch button is fixedly installed on the hollow tube, and the switch button is electrically connected to the leakage sensor through a wire;

[0010] An extension tube is provided below the hollow tube, and the hollow tube is slidably installed in a notch at the top of the extension tube. A plurality of adjusting threaded holes are equidistantly provided on the hollow tube and the extension tube, and a pair of the adjusting threaded holes are threadedly connected with hand-tightened bolts.

[0011] In a possible design, the hollow tube and the extension tube are both made of polyethylene.

[0012] In a possible design, two limit sliders are symmetrically fixedly arranged on the outer wall of the hollow tube, and a limit slideway for slidingly installing the limit sliders is provided on the extension tube, and the limit sliders are arranged to penetrate the limit slideway.

[0013] In one possible design, a lithium battery block is fixedly installed at the bottom of the inner wall of the extension tube, and the lithium battery block is electrically connected to the leakage sensor through a wire. A charging connector is fixedly installed at the bottom of the extension tube, and the charging connector is electrically connected to the lithium battery block through a wire.

[0014] In a possible design, an annular groove is provided on the outer wall of the extension tube, and an anti-slip sleeve is provided inside the annular groove, and the anti-slip sleeve is made of high-density sponge material.

[0015] In a possible design, a rope ring is fixedly provided at the lower end of the outer wall of the extension tube, and the rope ring is made of rubber material.

[0016] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0017] In the present application, when in use, the user holds the extension tube and uses the leakage sensor to detect leakage of electrical equipment. If leakage is detected, the leakage sensor transmits an electrical signal to the warning light, and the warning light flashes continuously to warn and remind. The user can move arbitrarily during the detection process, which is convenient to use and is conducive to improving the efficiency of leakage detection in a larger area. In addition, since the hollow tube and the extension tube made of polyethylene have good insulation properties, the risk of direct contact between the user and the device to be detected can also be reduced, thereby improving the safety protection of the user.

[0018] When it is necessary to perform leakage detection on equipment at a deeper level, the hand-tightening bolts can be unscrewed, the hollow tube can be pulled out for a certain distance, and then the hand-tightening bolts can be used to fix it, thereby extending the use length of the entire device and helping to improve the practicality of the device.

[0019] The utility model has the following beneficial effects:

[0020] The utility model adopts a walking stick structure, which is convenient for users to take and use. It can be moved arbitrarily during the detection process and is easy to use. It is beneficial to improve the efficiency of leakage detection in a larger area. The hollow tube and the extension tube are made of polyethylene with good insulation properties, which can also reduce the risk of direct contact between the user and the equipment to be detected, thereby improving the safety protection of the user.

[0021] The use length of the overall device of the utility model can be extended, which helps to improve the practicality of the device, and the maximum moving distance of the hollow tube is limited by the limit slider and the limit slideway to prevent the hollow tube from detaching from the extension tube, and at the same time prevent the hollow tube from rotating left and right, thereby facilitating the alignment of the adjustment threaded hole on the hollow tube and the adjustment threaded hole on the extension tube.

[0022] The utility model utilizes a lithium battery block to power the leakage sensor, thus avoiding the use of dry batteries for power supply, which is prone to battery leakage and causes circuit board damage. At the same time, the lithium battery block can be charged through a charging connector without the need to replace the battery, and is easy to use.

[0023] The utility model provides an anti-skid cover made of high-density sponge material, which is insulated and anti-skid and also has a good sweat-absorbing effect. By providing a rope ring, it can be wrapped around the arm to prevent the device from accidentally falling to the ground during use, thereby further improving the safety protection of the device.
