Description

Technical Field

[0001] The utility model relates to the technical field of ammonia concentration detection, in particular to an ammonia concentration early warning system for the environmental facilities of an animal laboratory. Background Technique

[0002] Laboratory animal facilities operate continuously, and various environmental factors are constantly changing, and regular monitoring and maintenance are also required. For the environmental conditions of laboratory animal facilities, there are national standardized regulations, and the detection items include temperature, relative humidity, ammonia concentration, noise, illuminance, air change rate, etc.

[0003] The patent document with the publication number of "CN207923831U" discloses an ammonia concentration early warning system for laboratory animal environmental facilities, which is installed in a breeding room. A plurality of breeding racks are arranged in the breeding room, and each group of breeding racks at least includes a plurality of breeding boxes arranged in sequence from bottom to top, etc.

[0004] Although there are ammonia concentration early warning devices for laboratory animal environmental facilities in the prior art, most of the existing alarms are fixed on the wall by screws, resulting in inconvenient installation and disassembly of the alarms. Content of the Utility Model

[0005] The purpose of the utility model is to solve the following disadvantages in the prior art. Most of the existing alarms are fixed on the wall by screws, resulting in inconvenient installation and disassembly of the alarms, and an ammonia concentration early warning system for the environmental facilities of an animal laboratory is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] An ammonia concentration early warning system for the environmental facilities of an animal laboratory includes an alarm and two bumps, and the two bumps are respectively fixedly connected to both sides of the alarm;

[0008] A fixing component is installed on the alarm, and the fixing component includes a suction cup, a circular cavity, an air delivery pipe, a hinged plate, and a second airbag. The circular cavity is fixedly connected to the alarm, the suction cup is fixedly communicated with the circular cavity, the two hinged plates are respectively hinged to the bumps, the second airbag is fixedly connected between the two hinged plates, and the air delivery pipe is fixedly communicated between the second airbag and the circular cavity.

[0009] Preferably, the fixing component further includes a spring and a pull rod. The spring is fixedly communicated between the two hinged plates, the pull rod is fixedly connected to the alarm, and both ends of the pull rod are respectively slidably connected to the hinged plates.

[0010] Preferably, two wires are electrically connected to the alarm. A disc is slidably connected to the alarm, and positive and negative wires are respectively provided on the disc.

[0011] Preferably, a first airbag is fixedly connected between the disc and the alarm.

[0012] Preferably, a cylinder is slidably connected to one of the hinge plates. A piston is slidably connected inside the cylinder, and the piston is fixedly connected to one end of the pull rod.

[0013] Preferably, a connecting pipe is fixedly connected and communicated between the cylinder and the first airbag.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. The lower ends of the two hinge plates are separated from each other to stretch the second airbag. During the stretching process of the second airbag, a negative pressure is formed inside the suction cup, and the suction cup can tightly adsorb on the wall to fix the alarm. At the same time, when the hinge plate presses the second airbag again, the gas in the second airbag can be transmitted to the inside of the suction cup through the air delivery pipe. There is no negative pressure inside the suction cup, so it will not have an adsorption force on the wall, thus realizing the effect of quickly installing and disassembling the alarm.

[0016] 2. Since the disc is made of magnetic material, it can be adsorbed on the alarm. At the same time, the positive and negative poles on the disc can be respectively attached to and connected to the wires on the alarm, so that after the alarm is fixed, the alarm can be electrically connected to an external controller through the wires and work.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Terms such as "upper", "lower", "left", "right", "middle", and "one" cited in the present invention are only for the convenience of clear narration, rather than to limit the scope of implementation of the present invention. The change or adjustment of their relative relationship, without substantial change in technical content, should also be regarded as the scope of implementation of the present invention.

[0023] Referring to Figures 1 - 3 , an ammonia concentration warning system for an animal laboratory environmental facility, includes an alarm 1 and two bumps 2, and the two bumps 2 are respectively fixedly connected to both sides of the alarm 1.

[0024] A fixing component is installed on the alarm 1. The fixing component includes a suction cup 12, a circular cavity 13, an air delivery pipe 14, a hinged plate 3, and a second airbag 10. The circular cavity 13 is fixedly connected to the alarm 1, the suction cup 12 is fixedly communicated with the circular cavity 13, the two hinged plates 3 are respectively hinged on the bumps 2, and the hinged plate 3 can swing with the connection point with the bump 2 as the fulcrum. The second airbag 10 is fixedly connected between the two hinged plates 3, and the air delivery pipe 14 is fixedly communicated between the second airbag 10 and the circular cavity 13. The fixing component also includes a spring 9 and a pull rod 11. The spring 9 is fixedly communicated between the two hinged plates 3, the pull rod 11 is fixedly connected to the alarm 1, and both ends are respectively slidably connected to the hinged plate 3. A long oval through groove is opened at the lower end of the hinged plate 3, and the end of the pull rod 11 slides in the through groove. The pull rod will not affect the flipping of the hinged plate 3. Two wires 7 are electrically connected to the alarm 1. A disc 6 is slidably connected to the alarm 1. Positive and negative wires are respectively provided on the disc 6. When the disc 6 is adsorbed to the alarm 1, the positive and negative poles on the disc 6 are respectively butted against the two wires 7, so as to realize the electrical connection between the alarm 1 and an external controller.

[0025] A cylinder 4 is slidably connected to one of the hinged plates 3. A piston 15 is slidably connected in the cylinder 4. The right end of the cylinder 4 is not in a sealed state. Therefore, when the piston 15 moves to the right in the cylinder 4, it will not be affected. The piston 15 is fixedly connected to the pull rod 11. A first airbag 8 is fixedly connected between the disc 6 and the alarm 1. A connecting pipe 5 is fixedly communicated between the cylinder 4 and the first airbag 8. When the lower ends of the two hinged plates 3 move to the middle, the piston 15 can move from the right end to the left end of the cylinder 4 and squeeze the gas in the cylinder 4 to enter the first airbag 8 through the connecting pipe 5. As the gas in the first airbag 8 increases, the disc 6 is pushed to move away from the alarm 1 and separate from each other. At the same time, the positive and negative poles are also separated from the wire 7, which is convenient for the movement of the alarm 1.

[0026] In the present utility model, during use, first, the positive and negative electrodes on the disc 6 are electrically connected to the controller in the external warning system respectively. Then, the lower ends of the two hinged plates 3 are pushed to move centrally, compressing the spring 9. Since the suction cup 12 is located in the north of the alarm 1, after the suction cup 12 is attached to a smooth wall, the hinged plates 3 are released. The hinged plates 3 are flipped under the elastic force of the spring 9, causing the lower ends of the two hinged plates 3 to move away from each other and stretching the second airbag 10. Since the second airbag 10 is connected to the suction cup 12 through the air delivery pipe 14, the inside of the suction cup 12 is in negative pressure during the stretching process of the second airbag 10. Therefore, the suction cup 12 can tightly adsorb on the wall, realizing the fixing effect on the alarm 1. At the same time, when the second airbag 10 is squeezed by the hinged plates 3 again, the gas in the second airbag 10 can be transmitted to the inside of the suction cup 12 through the air delivery pipe 14, and there is no negative pressure in the suction cup 12. Therefore, there is no adsorption force on the wall either, thus realizing the effect of quickly installing and disassembling the alarm.

[0027] When the lower ends of the two hinged plates 13 move away from each other, one of the hinged plates 13 can push the cylinder 4 to slide on the piston 15. At this time, when the piston 15 slides from the left side to the right side of the cylinder 4, the gas in the first airbag 8 can be sucked in through the connecting pipe 5. Thus, when there is no gas in the first airbag 8 anymore, since the disc 6 is made of magnet material, it can adsorb on the alarm 1. At the same time, the positive and negative electrodes on the disc 6 can be respectively attached to and connected with the wires 7 on the alarm 1. Therefore, after the alarm 1 is fixed, the alarm 1 can be electrically connected to the external controller through the wires 7 and work.

[0028] In the present utility model, unless otherwise clearly specified and limited, terms such as "installation", "connection", "linkage", "fixation" and the like shall be understood in a broad sense.

[0029] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitution or change, and all should be covered within the protection scope of the present utility model.
