Description

Technical Field

[0001] The invention relates to the technical field of fire-fighting electronic detectors, in particular to an electronic detector protection device for building fire-fighting equipment. Background Art

[0002] Building fire fighting equipment is a general term for equipment and facilities such as automatic fire alarm systems, automatic sprinkler systems, and fire hydrant systems used to prevent and extinguish building fires. Building fire fighting equipment is an important facility to ensure building fire safety and personnel evacuation safety. It is an important part of modern buildings and plays an important role in protecting buildings. It effectively protects the lives of citizens and the safety of national property. Electronic detectors are an important building fire fighting equipment that can detect the occurrence of fire in a timely manner and then sound an alarm, allowing people in the building to have more reaction time.

[0003] When the fire is uncontrollable, it will damage the electronic detector, resulting in a certain degree of waste. If the electronic detector can be protected after it sounds an alarm, this waste can be avoided. The existing conventional protection scheme is mainly based on two points. One is to cut off the wires after the fire occurs and the alarm is sounded to prevent the circuit from burning and causing damage to it. The second is to set a protective box on the outside so that it can play a protective role. If the box is sealed, the electronic detector will not be able to effectively sense the fire, and the protective box with an opening has a lot of room for improvement in its protection effect. Therefore, how to achieve dual protection in daily life and when a fire occurs is a technical problem that needs to be solved now. In this regard, the present invention provides an electronic detector protection device for building fire protection equipment to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 7 The present invention provides a technical solution: an electronic detector protection device for building fire protection equipment, comprising a mounting plate 1, a support plate 2 is fixed to the front of the mounting plate 1, an electronic detector body 301 is fixed to the top of the support plate 2, a cable 302 is fixed to the input end of the electronic detector body 301, a protective shell 4 is fixed between the front of the mounting plate 1 and the top of the support plate 2, a protective mechanism 600 is installed on the front of the mounting plate 1, and a protective component is installed on the outer side of the protective shell 4;

[0033] In the above-mentioned embodiment, the use of protective components improves the effect of daily protection, so that the electronic detector body 301 can be well protected in daily life without affecting normal monitoring work. Through the use of the protective mechanism 600, the interior of the protective shell 4 can be separated from the outside world, achieving the effect of blocking and isolating, and can play an effective fire-proof and heat-insulating role for the outside of the electronic detector body 301, making it difficult to be damaged or burned in a fire, and convenient for repeated use after recovery.

[0034] In this embodiment, the protection mechanism 600 is a structure for protecting the electronic detector when a fire occurs.

[0035] like Figure 1 , Figure 3 and Figure 7 As shown, the protection mechanism 600 includes an equipment box 601 fixed to the top of the protection shell 4, a placement cavity 602 opened inside the protection shell 4 and with openings on both sides of the front, a protection frame 603 slidably connected to the inner side of the placement cavity 602, a connecting plate 604 fixed to the top of the protection frame 603, a round rod 605 fixed to the top of the connecting plate 604, a driven wheel 606 sleeved on the outside of the round rod 605, a driving wheel 607 rotatably connected to the top of the protection shell 4 through a rotating shaft, a mounting frame 608 fixedly installed on the top of the protection shell 4, and a driving mechanism 609 fixedly installed on the inner side of the mounting frame 608.

[0036] It should be noted that if Figure 1 and Figure 2As shown, a top guard plate 5 located on the outside of the top of the protective shell 4 is fixed to the front of the mounting plate 1, a sliding ring 610 is fixed between the top of the support plate 2 and the front of the protective shell 4, and a sliding groove 611 with openings on both sides of the front for the sliding ring 610 to be inserted and slide is provided at the bottom of the protective frame 603. The sliding ring 610 is located on the side of the arc-shaped fixed frame 701 close to the electronic detector body 301, so that the protective frame 603 can move normally on the outside of the sliding ring 610 without affecting the normal state of the arc-shaped fixed frame 701. At the same time, the protective frame 603, the inner side of the arc-shaped fixed frame 701, the outer side of the sliding ring 610 and the inner side of the protective shell 4 are all located at the same center.

[0037] In addition, if Figure 1 and Figure 3 As shown, a placement groove 612 for the cable 302 to pass through and be placed is provided on the right side of the front of the protective housing 4 and the right side of the front of the protective frame 603. A blade 613 is fixedly installed on the inner side of the placement cavity 602 and the front of the protective frame 603. The blade 613 on the inner side of the placement cavity 602 is located on the right side of the electronic detector body 301 and on the side of the inner side of the placement cavity 602 close to the outside. The blade 613 on the front of the protective frame 603 is fixedly installed on the left side of the front of the protective frame 603, and the positions of the two blades 613 are consistent with the placement groove. The positions of 612 correspond to each other, and the two blades 613 can be tangent to each other during the movement. Specifically, the protection frame 603 can drive the corresponding blade 613 to move when rotating, and then use the tangency of the two blades 613 to simulate scissors, so as to quickly cut the cable 302, and the outer side of the cable 302 is connected to the outer side of the protective shell 4 by bolts, so that the cable 302 can be stably located on the inner side of the placement groove 612 and the blade 613 can be cut, preventing the cable 302 from being driven to move and unable to be cut normally.

[0038] At the same time, if Figure 4 As shown, the protection frame 603 includes a fireproof layer 6031, a first thermal insulation layer 6032 and a second thermal insulation layer 6033; the first thermal insulation layer 6032 is located between the opposite sides of the fireproof layer 6031 and the second thermal insulation layer 6033, the fireproof layer 6031 is located on the side away from the electronic detector body 301, the fireproof layer 6031 and the opposite side of the first thermal insulation layer 6032 are fixedly connected, the first thermal insulation layer 6032 and the opposite side of the second thermal insulation layer 6033 are fixedly connected, so that the fireproof layer 6031 can first block the fire in the external environment, and then perform auxiliary insulation through the first thermal insulation layer 6032 and the second thermal insulation layer 6033, the fireproof layer 6031 is a fireproof board, the first thermal insulation layer 6032 is a silicate fiber insulation board, and the second thermal insulation layer 6033 is a polystyrene foam board, so that it can have good fireproof and heat-insulating effects.

[0039] In addition, a rotating cavity is opened inside the protective shell 4 for the connecting plate 604 to rotate and is connected to the inside of the placement cavity 602, so that the connecting plate 604 can rotate normally. The top of the round rod 605 passes through the top of the protective shell 4, and the outer side of the round rod 605 is rotatably connected to the top of the protective shell 4 through a bearing, so that the round rod 605 can rotate stably.

[0040] It should also be noted that the driven wheel 606, the driving wheel 607 and the driving mechanism 609 are all located inside the equipment box 601. The output shaft of the driving mechanism 609 is fixedly connected to the top of the driving wheel 607. The driving wheel 607 and the driven wheel 606 are meshed with each other on opposite sides, so that the driving mechanism 609 can drive the driving wheel 607 to rotate, and then the driven wheel 606 can rotate. The driving mechanism 609 can be a servo motor.

[0041] In this embodiment, the protection component is a structure used to protect the electronic detector in daily life.

[0042] like Figure 5 and Figure 6 As shown, the protection component includes an arc-shaped fixed frame 701 fixed between the front side of the protective shell 4 and the top of the support plate 2, two connecting blocks 702 respectively fixed to the left and right sides of the front side of the arc-shaped fixed frame 701, a movable frame 703 fixed between the opposite sides of the two connecting blocks 702, a plurality of elastic members 704 fixed between the movable frame 703 and the opposite sides of the arc-shaped fixed frame 701, a plurality of supporting members 705 fixed between the movable frame 703 and the opposite sides of the arc-shaped fixed frame 701, and a plurality of through holes 706 opened between the movable frame 703 and one side of the front side of the arc-shaped fixed frame 701.

[0043] It should be noted that the connecting block 702 and the supporting member 705 are both high-temperature resistant elastic rubber blocks, which can allow the movable frame 703 to move appropriately under the connection of the two connecting blocks 702. The movable frame 703 is made of fireproof plastic, which can play a certain fireproof role while also being able to undergo a certain deformation, making it easier to block debris. The supporting member 705 can play a role of elastic support for the movable frame 703, allowing it to move more stably.

[0044] It should also be noted that the protective shell 4 and the arc-shaped fixing frame 701 are both made of the same material combination as the protection frame 603, so that they can play a good fire retardant and heat insulating effect after being closed.

[0045] The working principle of the above embodiment is:

[0046] In daily life, the movable frame 703 can withstand external impacts, thereby protecting the arc-shaped fixed frame 701, and the elastic member 704 and the support member 705 can also absorb the impact force to a certain extent, thereby improving the effect of daily protection, and the through hole 706 will not affect the entry of smoke. When a fire occurs, the electronic detector body 301 detects the air entering through the through hole 706 and then sends a fire signal to the main server, so that the relevant staff can quickly judge the current situation, start the driving mechanism 609, and drive the driving wheel 607 to rotate. The driven wheel 606 rotates and drives the connecting plate 604 to rotate through the round rod 605, so that the protective frame 603 moves out from the inner side of the placement cavity 602, so that it can cover the through hole 706, and quickly and stably cut the cable 302 through the two tangent blades 613, so that the interior of the protective shell 4 can be separated from the outside world. Under the cooperation of the fireproof layer 6031, the first thermal insulation layer 6032 and the second thermal insulation layer 6033, the outer side of the electronic detector body 301 can be effectively fireproofed and heat-insulated, so that it can be effectively protected in the event of a fire, and is easy to reuse.

[0047] Compared with the prior art, the electronic detector protection device for building fire protection equipment can withstand external impacts through the movable frame 703, thereby protecting the arc-shaped fixed frame 701, and can also absorb the impact force to a certain extent elastically under the cooperation between the elastic member 704 and the support member 705, thereby improving the effect of daily protection, so that the electronic detector body 301 can be well protected in daily life without affecting the normal monitoring work, and through the cooperative transmission of the driving wheel 607 and the driven wheel 606, the protection frame 603 can shield the through hole 706, and through The two tangent blades 613 quickly and stably cut the cable 302, thereby isolating the interior of the protective shell 4 from the outside world, thereby achieving the effect of blocking and isolating. The fireproof layer 6031, the first thermal insulation layer 6032 and the second thermal insulation layer 6033 cooperate with each other to effectively prevent and heat-insulate the outside of the electronic detector body 301, making it less likely to be damaged or burned in the event of a fire, and making it easy to recycle and reuse, thereby solving the problem that the electronic detector protection device of existing building fire protection equipment cannot provide both daily protection and fire protection effects.
