Description

Technical Field

[0001] This invention relates to the field of experimental chamber technology, and in particular to an experimental chamber volume adjustment system. Background Technology

[0002] The existing experimental chambers have a fixed and relatively large volume. When conducting experiments with small animals in small numbers, and when helium needs to be introduced into the chamber for experiments, the large volume of the chamber means that a lot of helium needs to be introduced. Since helium is expensive, this results in excessive helium costs and wastes valuable helium resources.

[0003] Currently, there is a lack of experimental cabins with adjustable internal space. Summary of the Invention

[0004] This invention addresses the problems and shortcomings of existing technologies by providing an experimental chamber volume adjustment system.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] The present invention provides an experimental chamber volume adjustment system, comprising an experimental chamber, characterized in that the experimental chamber comprises a chamber body, wherein a left sliding partition and a right sliding partition are slidably connected within the chamber body, and the inner cavity of the chamber body is divided into a left chamber chamber, a middle chamber chamber and a right chamber arranged sequentially from left to right by the left sliding partition and the right sliding partition.

[0007] The left end of the cabin is detachably connected to a left hatch corresponding to the left cabin chamber, the right end of the cabin is detachably connected to a right hatch corresponding to the right cabin chamber, and the middle part of the cabin is detachably connected to a middle hatch corresponding to the middle cabin chamber.

[0008] The left, middle, and right hatches are each equipped with an air inlet and an air outlet. The air inlets of the left, middle, and right hatches are equipped with electrically controlled air inlet valves, and the air outlets of the left, middle, and right hatches are equipped with electrically controlled air outlet valves.

[0009] The left chamber contains, from the inside out, a left telescopic cylinder, a left bellows, and a left telescopic drive mechanism for moving the left sliding partition. The left telescopic cylinder includes an inner left cylinder and an outer left cylinder, which are slidably connected. The left ends of the inner left cylinder and the left bellows are fixed to the inner wall of the left end of the chamber. The right ends of the outer left cylinder and the left bellows are fixed to the left sliding partition. The inner wall of the left telescopic cylinder serves as the inner wall of the left active cavity of the experimental animal.

[0010] The right chamber contains, from the inside out, a right telescopic cylinder, a right bellows, and a right telescopic drive mechanism for moving the right sliding partition. The right telescopic cylinder includes an inner right cylinder and an outer right cylinder, which are slidably connected. The right ends of the inner right cylinder and the bellows are fixed to the inner wall of the right end of the chamber. The left ends of the outer right cylinder and the bellows are fixed to the right sliding partition. The inner wall of the right telescopic cylinder serves as the inner wall of the right active cavity of the experimental animal.

[0011] The system also includes an external controller, which is used to control the extension and retraction of the left and right telescopic drive mechanisms according to different experimental space requirements.

[0012] The external controller is used to extend the left telescopic drive mechanism to increase the space of the left compartment when it receives an instruction that the left compartment is the current experimental compartment and the space of the left compartment needs to be increased; and to shorten the left telescopic drive mechanism to reduce the space of the left compartment when it receives an instruction that the left compartment is the current experimental compartment and the space of the left compartment needs to be reduced.

[0013] The external controller is used to control the right telescopic drive mechanism to extend to increase the space of the right compartment when it receives an instruction that the right compartment is the current experimental compartment and the right compartment needs to increase its space; and to control the right telescopic drive mechanism to shorten to reduce the space of the right compartment when it receives an instruction that the right compartment is the current experimental compartment and the right compartment needs to decrease its space.

[0014] The external controller is used to control the left telescopic drive mechanism and the right telescopic drive mechanism to either shorten or simultaneously shorten to increase the space of the central chamber when it receives an instruction that the central chamber is the current experimental chamber and the central chamber needs to be expanded; and to control the left telescopic drive mechanism and the right telescopic drive mechanism to either extend or simultaneously extend to reduce the space of the central chamber when it receives an instruction that the central chamber is the current experimental chamber and the central chamber needs to be reduced.

[0015] This invention enables the switching of different experimental environments in multiple chambers.

[0016] The positive and progressive effects of this invention are as follows:

[0017] This invention uses three independent chambers, which makes it easy to select different chambers for experiments according to different experimental needs, and introduce helium-containing gas into the chambers.

[0018] This invention increases or decreases the chamber space by extending and retracting an electric telescopic rod. By reducing the chamber space, the amount of helium used can be reduced, thus lowering the cost of helium and preventing the waste of precious helium resources. Attached Figure Description

Gas enters the left active chamber through the air intake on the left hatch 21. It receives the actual air pressure value detected by the left air pressure sensor 91. When the actual air pressure value in the left active chamber is greater than the corresponding set air pressure value and reaches the first set threshold, it controls the left electric telescopic rod 102 to start and the left door 101 to open so that the left active chamber and the middle active chamber are connected as the current experimental chamber. When the actual air pressure value detected by the left air pressure sensor 91 and the actual air pressure value detected by the middle air pressure sensor 92 both reach the corresponding set air pressure value, it controls the electric air intake valve on the left hatch 21 to close.

[0043] The external controller is used to control the electric intake valve on the right hatch 23 to open when it receives a direct air intake command for the right active chamber and the right active chamber is not set as the current experimental chamber.
