[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] like Figure 1 As shown: The utility model is a leakage detection device for fire protection facilities, comprising a detection frame 1, a detector 2 is fixedly installed on the top of the detection frame 1, two connecting wires 7 are fixedly connected to the port of the detector 2, and the other ends of the two connecting wires 7 are fixedly installed with a contact plate 13; a receiving frame 10 is fixedly installed inside the detection frame 1, two flip frames 3 are fixedly installed on the top of the receiving frame 10, and the interiors of the two flip frames 3 are rotated with contact frames 5 through transfer pins 4, and the two contact plates 13 are respectively connected to the upper parts of the corresponding contact frames 5, and the upper parts of the two contact frames 5 are provided with contact protection components 8; a detection contact component 6 is provided above the receiving frame 10, and a separation component 9 connected to the detection contact component 6 is provided inside the detection frame 1.

[0020] like Figure 2 、 3As shown, the detection contact assembly 6 includes a vertical rod 601, a lifting plate 602, a support frame 603, a support wheel 604 and a return spring 605; two vertical rods 601 are connected between the top plate of the detection frame 1 and the receiving frame 10, and a lifting plate 602 is slidably sleeved between the two vertical rods 601; both sides of the lifting plate 602 are fixedly connected to the support frame 603, and the outer and inner sides of any of the support frames 603 are rotatably connected to the support wheel 604, and the contact frame 5 is located between the two support wheels 604. Two return springs 605 are fixedly connected between the receiving frame 10 and the detection frame 1. By lifting the lifting plate 602, the support wheels 604 inside the support frame 603 can tighten the two contact frames 5.

[0021] like Figure 4 As shown, the separation assembly 9 includes a movable frame 901, a stretching belt 902, a connecting ring 903, a threaded barrel 904, a lifting screw 905, and a rotating handle 906. The movable frame 901 is fixedly installed inside the detection frame 1. The movable frame 901 is equipped with a stretching belt 902, a connecting ring 903, and a lifting screw 905 connected in sequence from top to bottom. The bottom of the movable frame 901 is fixedly sleeved with a threaded barrel 904. The stretching belt 902 is connected to the top of the movable frame 901. The lifting screw 905 passes through the lifting screw 905 and is threadedly sleeved with the lifting screw 905. The bottom end of the lifting screw 905 is fixedly connected to the rotating handle 906. By pressing down the lifting plate 602, the two support wheels 604 move downward, eliminating the vertical support for the contact frame 5, and quickly completing the separation of the two contact frames 5, so as to facilitate the replacement of fire protection equipment leakage detection at different locations.

[0022] like Figure 4 As shown, the interior of the movable frame 901 is fixedly sleeved with an extension tube 11, and the stretching belt 902 is rotatably connected to the movable frame 901 through the extension tube 11. This design enables the stretching belt 902 to enter the movable frame without restriction.

[0023] like Figure 5 As shown, the contact protection assembly 8 includes a contact carriage 801, a contact head 802, a contact piece 803, and a take-up spring 804. The contact carriage 801 is inserted into the contact frame 5. The contact carriage 801 is U-shaped, with both ends facing inward and the lower end of the U bent downward. The contact head 802 is connected to the upper end of the contact carriage 801, and the contact piece 803 is fixedly connected to the outer side of the lower end of the contact carriage 801. Each contact piece 803 corresponds to a contact plate 13. A take-up spring 804 is installed between the notch of the contact carriage 801 and the contact frame 5. This design reduces friction between the contact plate 13 and the fire protection equipment during detection, preventing damage to the contact plate 13 that could render the detector 2 inoperable.

[0024] like Figure 1 As shown, two handle frames 12 arranged front and back are installed at the bottom of the detection frame 1, and the two handle frames 12 are symmetrically distributed with the axis of the detection frame 1 as the center, so as to facilitate the detection frame 1 to be carried and supported.

[0025] Working principle: First, the detector 2 is fixedly installed on the top of the detection frame 1, and then two contact frames 5 are rotatably sleeved inside the detection frame 1, and then the contact plate 13 is rotatably supported.

[0026] By fixedly connecting a connecting wire 7 between the contact plate 13 and the detector 2, leakage detection of the fire-fighting equipment in contact is achieved, and a contact slide 801 is movably sleeved inside the two contact frames 5, and a contact head 802 and a contact piece 803 are fixedly installed on the outer wall of the contact slide 801, so that the contact piece 803 and the contact plate 13 are located in the same horizontal plane, and the contact head 802 is in contact with the fire-fighting equipment; then a tightening spring 804 is fixedly connected between the contact slide 801 and the contact frame 5, thereby pushing the contact slide 801 to separate the contact piece 803 from the contact plate 13 when not detecting, and then protecting the contact plate 13, reducing the scratches on the contact plate 13 when moving the contact frame 5, and preventing the contact plate 13 from being damaged, which makes the detector 2 unusable. By movably sleeved with a lifting plate 602 on the outside of the two vertical poles 601, the support frame 603 is slidably supported, so that the support wheel 604 inside the support frame 603 contacts the contact frame 5, and then supports the contact frame 5; a reset spring 605 is fixedly installed between the lifting plate 602 and the detection frame 1, so that the support wheel 604 moves upward to retract the two contact frames 5 and contact the fire-fighting equipment; and then a lifting screw 905 is threadedly sleeved on the internal of the movable frame 901, so that the tensile belt 902 at the top of the lifting screw 905 is connected to the lifting plate 602, thereby driving the lifting plate 602 to move downward by rotating the lifting screw 905, so that the two support wheels 604 move downward; after canceling the vertical support for the contact frame 5, the two contact frames 5 are quickly separated, so as to facilitate the replacement of leakage detection of fire-fighting facilities at different positions.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
