Small animal swimming test device

Technical field:

The utility model relates to a kind of small animal swimming test device that is used for exercise physiological experiment.

Background technology:

In physiology of exercise research, standard animal movement mode and how to drive that the animal follow procedure moves be the problem that zoopery must solve how, and the swimming test of animal is wherein extremely important a kind of mode, but, the device that is used for big white mouse swimming at present mainly is pond and water-circulating pump, fetch water and water is entered the pond forms certain orientation from following outflow current from water surface high level with pump, big white mouse is stem all the time, but current have dead angle and not steady, simultaneously, flow velocity is non-adjustable, water temperature is uncontrollable, wants to increase the exercise load of animal, needs additional weight on its tail, in addition, device can't move.

Summary of the invention:

Main purpose of the present utility model is to overcome above deficiency and a kind of current that do not have dead angle and turbulent flow is provided, and current are adjustable, controlled water temperature, and device can freely be moved, and forms the small animal swimming test device in the hidden steady laminar flow waters that whirlpool is arranged.

The technical scheme that its technical problem that solves the utility model adopts is: it is made up of swimming pool and water pump, it is characterized in that: swimming pool is by inner core 1, urceolus 2, steel mesh 3, underframe 4, stay pipe 5 constitutes, urceolus 2 is supported on two fixing in the underframe 4 stay pipes 5, fix four wheels 6 below the underframe 4, the below of urceolus 2 keeps flat the steel mesh 3 of belt supporting frame, heart position perforate therein, put annular steel pipe 7 and welded together on the steel mesh 3,1 of inner core therein, the top of urceolus 2, cut four stay pipe 14 and fixed heads 12 that are mutually 90 °, in their centre connecting plate 13 is arranged, one side of connecting plate 13 is fixed on the fixed head 12 with screw, another side is welded on the stay pipe 14, is sidelong stay pipe 15 in the fixed head 12, and the suitable for reading of inner core 1 is supported in above it, four fixed heads 12 that are mutually 90 ° are connected with urceolus 2 usefulness bolt with inner core 1 respectively, at the bottom opening of urceolus 2 and underframe 4 and fixing impeller 8 respectively, leak-proof device 9, little synchronizing wheel 19, stepper motor 11 and big synchronizing wheel 10.

The utility model can also adopt following technical measures: the two ends of described stay pipe 14 should be cut into the identical shape of radian with inner core 1 and urceolus 2 barrels respectively.

Advantage and the good effect that the utlity model has are: because of inner core 1 and urceolus 2 for suit so form the swimming lane that goes in ring, current do not have dead angle and turbulent flow, and can form hidden stably whirlpool and not have the cavity, the flow velocity and the water temperature of current are adjustable, be convenient to control, device simple in structure, and random shift position.

Embodiment:

For further understanding summary of the invention characteristics of the present utility model and effect following examples for example now, and conjunction with figs. is described in detail as follows, and sees also Fig. 1-Fig. 3.

As shown in Figure 1: this device is made up of inner core 1, urceolus 2, steel mesh 3, underframe 4, stay pipe 5,14,15, wheel 6, fixed head 12, connecting plate 13, stepper motor 11, impeller 8, synchronizing wheel transmission, urceolus 2 is supported on two fixing stay pipes 5 of underframe 4 intermediate layers, be fixed with four wheels 6 below the underframe 4, below in the urceolus 2 keeps flat the steel mesh 3 of belt supporting frame, be used for preventing white mouse swimming excessive fatigue when power exhausts, scurry at the bottom of 2 of the urceolus and block impeller and rotate.Annular steel pipe 7 is installed on steel mesh 3, it is welded together with steel mesh 3, circular hole is opened at the middle position of steel mesh 3, size is identical with inner core 1 external diameter, above inner core 1 just is placed on, it can also prevent that inner core 1 is in urceolus 2, because of the effect of swirling water current field is rocked, inner core 1 is a suit with urceolus 2, water inlet and form annular swimming lane in the space of centre, go out urceolus 2 in order to prevent inner core 1 come-up, in their upper end, increase by four stay pipes 15 that are mutually 90 °, its two ends have radian respectively, and it is identical with the cylindrical shell radian of inner core 1 and urceolus 2, fixed head 12 usefulness bolt connect inner core 1 and urceolus 2, put annular brace pipe 15 at the inner crest face of fixed head 12, the crimping suitable for reading of inner core 1 rides over above it, one side of connecting plate 13 is connected with fixed head 12 with screw, another side is welded on the stay pipe 14, inner core 1 and urceolus 2 fuse like this, at the fixing impeller 8 of the bottom opening of urceolus 2, leak-proof device 9 and little synchronizing wheel 19, relevant position, bottom perforate at underframe 4, fixing with stepping motor 11, the toothed belt 20 of cover on big 10, two synchronizing wheels of synchronizing wheel is when stepper motor 11 drives impeller 8 rotations by the synchronizing wheel transmission, leak-proof device 9 can prevent that the interior water from outwards flowing out, impeller 8 fluctuation water flow along annular swimming lane, and current steadily do not have dead angle and turbulent flow, and white mouse is when extremely tired trip is motionless, still can drift about along swimming lane, because of under the effect of impeller rotation, the current rotation forms steadily, hidden whirlpool laminar flow again, because of there being stopping of inner core 1 not have the eddy current cavity, white mouse can be along whirlpool directly down, just equals to have increased heavy burden but white mouse must overcome the downward power that whirlpool causes, so help experiment.The adjusting of flow velocity and temperature controlling all adopt prior art, as shown in Figure 2: the rotating speed of stepper motor 11 is by 22 controls of current adjusting apparatus, urceolus 2 bottoms are fixed with water temperature controller 23, sensor 16 and thermoelectric heater 17, realize the automatic control of water temperature and kept water temperature constant, intake-outlet 18 is installed in the bottom of urceolus 2, realize water inlet with manually-operated gate, the water level height of water outlet and adjusting swimming pool, help the cleaning of swimming pool simultaneously, discharging white mouse class just and foreign material, four wheels 6 are installed on the underframe 4, can be as required, the position of mobile swimming pool at any time.Instrument control cabinet 21 as shown in Figure 3, be fixed on the interlude of urceolus 2 outer walls, interior dress current velometer 22, water temperature controller 23 and band lamp power switch 24, they are all controlled by panel, under the situation of certain water temperature and water flow velocity, can measure the white mouse physiological change after the large amount of exercise at short notice.Its advantage is: simple in structure, install easily, and long service life, conveniently moving, cost is low.
