Meanwhile, in order to improve the stability of the supporting plate 341 during lifting, two limiting angle steels 345 are vertically and fixedly connected to the corner positions of the supporting plate 341, and the inner side walls of the limiting angle steels 345 are attached to the corners of the supporting plate 341. Two limiting angle steels 345, the directional rod 342 and the threaded rod 343 are respectively positioned at four corner positions of the supporting plate 341.
One of the two second driving members 313 is fixed on the directional rod 342, and the other is fixed on the angle-limiting angle 345 far away from the moving section 311.
The movable trolley 6 is placed in the breeding room, and the breeding cage to be replaced after cleaning is stacked on the movable trolley 6. When the laboratory mouse is replaced by a worker, the movable trolley 6 is pushed to the position of the breeding cage to be replaced, and the laboratory mouse is taken out from the table top of the movable trolley 6 and placed into a new breeding cage.
A positioning assembly 7 is arranged in the breeding room, the positioning assembly 7 comprises a plurality of first distance measuring instruments 71 and second distance measuring instruments 72, the first distance measuring instruments 71 are installed on the wall of the moving area 1 far away from the continuation section 312, and the first distance measuring instruments 71 horizontally face the other end of the moving area 1.
The second distance measuring instrument 72 is located directly above the first measuring instrument for measuring the real-time position of the air curtain box 4, so as to regulate the position of the air curtain box 4.
It should be noted that, the embodiment of the present application is only illustrated by using a laboratory mouse, and does not represent that only the laboratory mouse is used, and equivalently, the breeding room in the present application can be arranged and the cage changing operation can be performed when other laboratory animals are bred.
The implementation principle of the experimental animal breeding room in the embodiment of the application is as follows: the mobile area 1 of the breeding room is of a straight strip corridor-shaped structure, and breeding cages for breeding experimental animals in multiple rows are placed in the breeding areas 2 on two sides.
When the cage operation is changed to experimental animals, the staff can promote the removal shallow 6 that is equipped with clean breed cage and move in removal district 1, after first distance measuring instrument 71 recorded the position of travelling car and staff, air curtain case 4 can be along with the travelling car simultaneous movement, and produce the clean air curtain after the filtration disinfection around travelling car and staff, with the contact that reduces the microorganism in the breed room and staff, make the staff can stop at any time and change the cage, the work load of staff has been reduced, and the work efficiency is improved.
On the other hand, the cage changing system of the experimental animal breeding room comprises a main control module, a movable trolley 6 and an air curtain box 4, wherein the main control module is used for receiving information and performing data processing and controlling the air curtain box 4 to move along with the movable trolley 6;
the sensing module is connected with the main control module, comprises a first distance measuring instrument 71 for measuring the position of the mobile cart 6, and transmits the position information of the mobile cart 6 to the main control module;
and the driving module is connected with the main control module, is controlled by the main control module, and comprises a first driving part 48, a second driving part 313 and a third driving part 344, and is used for controlling the movement of the air curtain box 4.
When the cage of the worker is changed in the moving area 1, the sensing module measures the distance between the sensing module and the moving trolley 6 at any time, and transmits the position information of the moving trolley 6 to the main control module. The main control module controls the start and stop of the first driving member 48 by calculation, so that the air curtain box 4 can continuously move along with the moving cart 6, and thus, the air curtain box can be kept right above the moving cart 6.
When the air curtain box 4 needs maintenance, the air curtain box 4 is moved to the position of the continuation section 312 by controlling the first driving member 48, then the second driving member 313 is started to separate the continuation section 312 from the air curtain box 4 until the air curtain box 4 is completely overlapped on the supporting plate 341, and then the third driving member 344 is started to drive the air curtain box 4 to descend to a proper height so that a worker can maintain the air curtain box 4.
The sensing module further comprises a second distance meter 72 for determining the position of the air curtain box 4. The main control module compares the data transmitted by the first distance measuring instrument 71 and the second distance measuring instrument 72, and adjusts the position of the air curtain box 4, so that the moving error of the position of the air curtain box 4 can be effectively reduced, and the clean air curtain is maintained around the movable trolley 6 or the staff.
The cage changing system further comprises a cruising module communicated with the main control module and used for monitoring the electric quantity of the air curtain box 4 and sending the electric quantity information to the main control module. When the electric quantity of the air curtain box 4 is low, the main control module can control the air curtain box 4 to move to the socket 5 until a plug on the air curtain box 4 is inserted into the socket 5 for charging.
The embodiment of the application provides an experimental animal the cage replacing system of the culture room has the implementation principle that:
in the case of a moving area 1 without obstacles (staff or moving carts 6), the first distance measurement-the measured distance-is equivalent to the length of the cultivation room. At this time, the main control system controls the air curtain box 4 to reciprocate on the moving track 3 through the first driving member 48, so as to sterilize and filter the air in the cultivation room, thereby ensuring a clean environment in the cultivation room.
When the battery electric quantity that the module of continuing a journey detected air curtain case 4 is lower, can transmit electric quantity information to host system, host system control air curtain case 4 removes 5 departments of socket and carries out automatic charging.
After the staff enters the moving area 1, the distance measured by the first distance measuring instrument 71 changes, and the main control system adjusts the moving track of the air curtain box 4, so that the air curtain box 4 forms a clean air curtain around the staff along with the staff to ensure the cleanness of the surrounding environment of the staff in the cultivation room.
When the worker needs to maintain the air curtain box 4, a maintenance command is input to the main control module, the main control module temporarily suspends receiving of information transmitted by the first distance measuring instrument 71, the air curtain box 4 is moved to the continuation section 312 by controlling the driving module, the bearing plate 341 in which the air curtain box 4 is placed is lowered after the continuation section 312 is rotated and opened, and then the worker maintains the air curtain box 4.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
